  5. The social surplus of broadband initiatives in compulsory education

    Directory of Open Access Journals (Sweden)

    David Peter Parsons

    2016-10-01

    Full Text Available In 2010, the New Zealand government embarked upon an ambitious programme of broadband infrastructure investment, a process that will continue until at least 2019. Part of this investment is specifically targeted at compulsory education, with initiatives that include bringing fibre connections to the school gate, supporting on-site network upgrades (including wireless and providing teaching, learning and support services delivered through these networks. Such investments are not made without some projections of the likely rate of return, but calculating return on investment (ROI in educational broadband is complex, as it encompasses a range of factors. This article reports on an interview-based study engaging a range of stakeholders in educational broadband provision. The study utilises a research model that considers the various elements of social surplus, namely; producer surplus (savings, producer surplus (profit and consumer surplus (perceived value over and above cost, to explore the elements of social surplus that have been used to define educational broadband ROI calculations and justify the scale of investment. The results indicate that all three components of social surplus are relevant, though the concept of profit can only be seen in the broader context of long term contributions to the economy. A note of caution is that projections of ROI based only on positive returns fail to acknowledge the potential for some innovations to actually increase costs. Further, purely quantitative models do not properly take into account qualitative components of consumer surplus.

    The purpose of this paper is to provide the Department of Energy's (DOE) safeguards and security community with some insights on an important management initiative by the Office of Security Evaluations (OSE). The paper will present the ''what, where, who, when, and why'' of a new Evaluation Program. The Evaluation Program will be comprised of a continuing series of regular and special evaluations of DOE safeguards and security programs and policies. The evaluations will be integrative and ''crosscutting,'' i.e. will extend across DOE organizational lines. Evaluations will be offered as positive advisories to DOE managers with safeguards and security responsibilities and will not be rated. They will complement the ongoing OSE Inspection Program of inspections conducted by OSE's Inspection Division. The purpose for the evaluations is to establish an accurate and current assessment of the effectiveness and status of safeguards and security programs and policies and to provide DOE managers with required information on program and policy effectiveness

  15. A Hybrid Genetic Programming Method in Optimization and Forecasting: A Case Study of the Broadband Penetration in OECD Countries

    Directory of Open Access Journals (Sweden)

    Konstantinos Salpasaranis

    2012-01-01

    Full Text Available The introduction of a hybrid genetic programming method (hGP in fitting and forecasting of the broadband penetration data is proposed. The hGP uses some well-known diffusion models, such as those of Gompertz, Logistic, and Bass, in the initial population of the solutions in order to accelerate the algorithm. The produced solutions models of the hGP are used in fitting and forecasting the adoption of broadband penetration. We investigate the fitting performance of the hGP, and we use the hGP to forecast the broadband penetration in OECD (Organisation for Economic Co-operation and Development countries. The results of the optimized diffusion models are compared to those of the hGP-generated models. The comparison indicates that the hGP manages to generate solutions with high-performance statistical indicators. The hGP cooperates with the existing diffusion models, thus allowing multiple approaches to forecasting. The modified algorithm is implemented in the Python programming language, which is fast in execution time, compact, and user friendly.

  2. Alberta industrial synergy CO2 programs initiative

    International Nuclear Information System (INIS)

    Yildirim, E.

    1998-01-01

    The various industrial sectors within Alberta produce about 350,000 tonnes of CO 2 per day. This presentation was concerned with how this large volume and high concentration of CO 2 can be used in industrial and agricultural applications, because every tonne of CO 2 used for such purposes is a tonne that does not end up in the atmosphere. There is a good potential for an industrial synergy between the producers and users of CO 2 . The Alberta Industrial Synergy CO 2 Programs Initiative was established to ultimately achieve a balance between the producers of CO 2 and the users of CO 2 by creating ways to use the massive quantities of CO 2 produced by Alberta's hydrocarbon-based economy. The Alberta CO 2 Research Steering Committee was created to initiate and support CO 2 programs such as: (1) CO 2 use in enhanced oil recovery, (2) creation of a CO 2 production inventory, (3) survey of CO 2 users and potential users, (4) investigation of process issues such as power generation, oil sands and cement manufacturing, and (5) biofixation by plants, (6) other disposal options (e.g. in depleted oil and gas reservoirs, in aquifers, in tailings ponds, in coal beds). The single most important challenge was identified as 'rationalizing the formation of the necessary infrastructure'. Failing to do that will greatly impede efforts directed towards CO 2 utilization

    Dooraghi, Michael [National Renewable Energy Lab. (NREL), Golden, CO (United States)

    2015-09-01

    The Atmospheric Radiation Measurement program (ARM) maintains a fleet of monitoring stations to aid in the improved scientific understanding of the basic physics related to radiative feedback processes in the atmosphere, particularly the interactions among clouds and aerosols. ARM obtains continuous measurements and conducts field campaigns to provide data products that aid in the improvement and further development of climate models. All of the measurement campaigns include a suite of solar measurements. The Solar Radiation Research Laboratory at the National Renewable Energy Laboratory supports ARM's full suite of stations in a number of ways, including troubleshooting issues that arise as part of the data-quality reviews; managing engineering changes to the standard setup; and providing calibration services and assistance to the full fleet of solar-related instruments, including pyranometers, pyrgeometers, pyrheliometers, as well as the temperature/relative humidity probes, multimeters, and data acquisition systems that are used in the calibrations performed at the Southern Great Plains Radiometer Calibration Facility. This paper discusses all aspects related to the support provided to the calibration of the instruments in the solar monitoring fleet.

    1996-01-01

    The Reduced Enrichment for Research and Test Reactors (RERTR) program has been successful in furthering efforts to reduce and eventually eliminate highly enriched uranium (HEU) from international commerce. Three key policy initiatives are underway to further promote the RERTR program. The first initiative is implementation of a new nuclear weapons nonproliferation policy concerning foreign research reactor spent nuclear fuel. Under this policy, the United States will accept over the next 13 years research reactor spent fuel from 41 countries that have converted or plan to convert to use LEU fuels. The second initiative is to pursue cooperative efforts to expand the RERTR program to new regions of the globe, including Russia and China. The third initiative is to restart the advanced LEU fuels development program at the Argonne National Laboratory in order to increase the number of reactors that can convert to use LEU without significant detriment to their performance

    Cambridge, M.; Wolfenden, A.K.

    1996-12-31

    California`s Expedited Remedial Action Program (ERAP) created a comprehensive program that promotes an equitable and expedited approach for redevelopment of properties contaminated with hazardous substances. This bill embodies an emerging trend in environmental policy that permits flexibility, cooperation and creativity without compromising protection to public health or the environment. Within the California Environmental Protection Agency, the Department of Toxic Substances Control (DTSC) is promoting a number of programs to facilitate the restoration of contaminated properties as part of its Brownfields initiative. ERAP represents a potentially more efficient process to remediate sites by minimizing economic risks through a clearly identified liability scheme, indemnifying future owners through a covenant not to sue, and providing risk based cleanups that are based on the permanent use of the site.

    2007-06-01

    In the absence of formal registry data, the volume and causes of organ failure in Syria are difficult to establish with certainty. However, we evaluated in this study the extent of organ failure by collecting data from health care authorities in different medical institutions who are involved in caring for patients with organ failure. Subsequently, we assessed the problem of the widening gap between organ supply and demand in our country and we highlighted the obstacles to initiating a national deceased donation program as a viable option to address the challenge of organ shortage. The estimated prevalence of corneal blindness in Syria is 2.3 per one thousand population. The estimated incidence of viral-induced cirrhosis is 49 - 67 per one million population (pmp); these include both HCV and HBV, which constitute the leading causes of liver failure. We estimated the incidence of end-stage renal disease (ESRD) to be from 80 - 100 pmp. Obstacles to initiating a national deceased donation program include lack of awareness of the public at large and health care professionals to the importance of organ donation and transplantation. Other obstacles include lack of adequate resources in terms of finance, personnel and services and the unavailability of a national center for organ transplantation that influences public attitude, sets national guidelines and supervises all activities related to organ donation and transplantation.

    2016-12-30

    The Sun Grant Initiative partnered with the US Department of Energy (DOE) in 2008 to create the Regional Biomass Feedstock Partnership Competitive Grants Program. The overall goal of this project was to utilize congressionally directed funds to leverage the North Central Regional Sun Grant’s Competitive Grant program at South Dakota State University (SDSU) to address key issues and research gaps related to development of the bioeconomy. Specific objectives of this program were to: 1. Identify research projects through a Regional Competitive Grants program that were relevant to the sustainable production, harvest, transport, delivery, and processing/conversion of cost-competitive, domestically grown biomass. 2. Build local expertise and capacity at the North Central Regional Sun Grant Center at SDSU through an internal selection of key bioenergy research projects. To achieve these, three nationwide Request for Applications (RFA) were developed: one each in 2008, 2009, and 2010. Internal, capacity building projects at SDSU were also selected during each one of these RFAs. In 2013 and 2015, two additional Proof of Concept RFAs were developed for internal SDSU projects. Priority areas for each RFA were 1) Biomass feedstock logistics including biomass harvesting, handling, transportation, storage, and densification; 2) Sustainable biomass feedstock production systems including biomass crop development, production, and life-cycle analysis; 3) Biomass production systems that optimize biomass feedstock yield and economic return across a diverse landscape while minimizing negative effects on the environment and food/feed production; and 4) Promotion of knowledge-based economic development in science and technology and to advance commercialization of inventions that meet the mission of the Sun Grant Initiative. A total of 33 projects were selected for funding through this program. Final reports for each of these diverse projects are included in this summary report

    Sawyer, J. C., Jr.

    1993-01-01

    The activities of the joint NASA/DOE/DOD Nuclear Propulsion Program Technical Panels have been used as the basis for the current development of safety policies and requirements for the Space Exploration Initiatives (SEI) Nuclear Propulsion Technology development program. The Safety Division of the NASA Office of Safety and Mission Quality has initiated efforts to develop policies for the safe use of nuclear propulsion in space through involvement in the joint agency Nuclear Safety Policy Working Group (NSPWG), encouraged expansion of the initial policy development into proposed programmatic requirements, and suggested further expansion into the overall risk assessment and risk management process for the NASA Exploration Program. Similar efforts are underway within the Department of Energy to ensure the safe development and testing of nuclear propulsion systems on Earth. This paper describes the NASA safety policy related to requirements for the design of systems that may operate where Earth re-entry is a possibility. The expected plan of action is to support and oversee activities related to the technology development of nuclear propulsion in space, and support the overall safety and risk management program being developed for the NASA Exploration Program.

    The 3D Elevation Program (3DEP) initiative is accelerating the rate of three-dimensional (3D) elevation data collection in response to a call for action to address a wide range of urgent needs nationwide. It began in 2012 with the recommendation to collect (1) high-quality light detection and ranging (lidar) data for the conterminous United States (CONUS), Hawaii, and the U.S. territories and (2) interferometric synthetic aperture radar (ifsar) data for Alaska. Specifications were created for collecting 3D elevation data, and the data management and delivery systems are being modernized. The National Elevation Dataset (NED) will be completely refreshed with new elevation data products and services. The call for action requires broad support from a large partnership community committed to the achievement of national 3D elevation data coverage. The initiative is being led by the U.S. Geological Survey (USGS) and includes many partners—Federal agencies and State, Tribal, and local governments—who will work together to build on existing programs to complete the national collection of 3D elevation data in 8 years. Private sector firms, under contract to the Government, will continue to collect the data and provide essential technology solutions for the Government to manage and deliver these data and services. The 3DEP governance structure includes (1) an executive forum established in May 2013 to have oversight functions and (2) a multiagency coordinating committee based upon the committee structure already in place under the National Digital Elevation Program (NDEP). The 3DEP initiative is based on the results of the National Enhanced Elevation Assessment (NEEA) that was funded by NDEP agencies and completed in 2011. The study, led by the USGS, identified more than 600 requirements for enhanced (3D) elevation data to address mission-critical information requirements of 34 Federal agencies, all 50 States, and a sample of private sector companies and Tribal and local

    At present, broadband radiometric measurements of LEDs with uniform and low-uncertainty results are not available. Currently, either complicated and expensive spectral radiometric measurements or broadband photometric LED measurements are used. The broadband photometric measurements are based on the CIE standardized V(λ) function, which cannot be used in the UV range and leads to large errors when blue or red LEDs are measured in its wings, where the realization is always poor. Reference irradiance meters with spectrally constant response and high-intensity LED irradiance sources were developed here to implement the previously suggested broadband radiometric LED measurement procedure [1, 2]. Using a detector with spectrally constant response, the broadband radiometric quantities of any LEDs or LED groups can be simply measured with low uncertainty without using any source standard. The spectral flatness of filtered-Si detectors and low-noise pyroelectric radiometers are compared. Examples are given for integrated irradiance measurement of UV and blue LED sources using the here introduced reference (standard) pyroelectric irradiance meters. For validation, the broadband measured integrated irradiance of several LED-365 sources were compared with the spectrally determined integrated irradiance derived from an FEL spectral irradiance lamp-standard. Integrated responsivity transfer from the reference irradiance meter to transfer standard and field UV irradiance meters is discussed.

    A growing number of children are experiencing marital transition. The effects of divorce on children have typically been considered deleterious, although factors can buffer the difficulty of postdivorce adjustment. One of these factors is a positive relationship with a parental figure. Unfortunately, divorce often overwhelms parents with a series of changes that compromise their parenting skills. One new approach to improving parenting after divorce is mindful parenting, which aims to enhance interpersonal and emotional connection in the parent-child relationship. This program is intended to facilitate parents' self-awareness, their mindfulness, and their intentionality in responding to their child's needs. The present study reports on the implementation of the Mindful Parenting Program, delivered in two groups to 12 recently divorced parents with preschool-aged children. Program effectiveness was conducted on two levels. First, mindfulness measured by the Toronto Mindfulness Scale revealed significant increases over the intervention and posttest period. Second, in-home behavioral observations conducted pre- and postintervention revealed no changes in parent-child relationships. These findings are discussed within the larger context of facilitating effective parenting postdivorce.

    1989-01-01

    Unique extraction optics (90 x 90 mrads) at the NSLS U4IR line offer high brightness beams at up to mm wavelengths with a ∼1ns pulse structure. Radiation from this port has now been carefully characterized and agrees well with calculations, making it 100--1000 times brighter than conventional sources in the middle and far infrared regions. Using rapid scan Michelson interferometers with liquid He cooled bolometer detectors we have been able for the first time to measure molecule substrate vibrations in surface science. We have also made the first measurements of the transmission of a film of the high Tc material YBaCuO in the BCS gap region. These initial experiments have demonstrated the advantages of the superior signal to noise available from this infrared beamline. 19 refs., 6 figs

  16. Broadband Liner Optimization for the Source Diagnostic Test Fan

    2012-01-01

    The broadband component of fan noise has grown in relevance with the utilization of increased bypass ratio and advanced fan designs. Thus, while the attenuation of fan tones remains paramount, the ability to simultaneously reduce broadband fan noise levels has become more appealing. This paper describes a broadband acoustic liner optimization study for the scale model Source Diagnostic Test fan. Specifically, in-duct attenuation predictions with a statistical fan source model are used to obtain optimum impedance spectra over a number of flow conditions for three liner locations in the bypass duct. The predicted optimum impedance information is then used with acoustic liner modeling tools to design liners aimed at producing impedance spectra that most closely match the predicted optimum values. Design selection is based on an acceptance criterion that provides the ability to apply increased weighting to specific frequencies and/or operating conditions. Typical tonal liner designs targeting single frequencies at one operating condition are first produced to provide baseline performance information. These are followed by multiple broadband design approaches culminating in a broadband liner targeting the full range of frequencies and operating conditions. The broadband liner is found to satisfy the optimum impedance objectives much better than the tonal liner designs. In addition, the broadband liner is found to provide better attenuation than the tonal designs over the full range of frequencies and operating conditions considered. Thus, the current study successfully establishes a process for the initial design and evaluation of novel broadband liner concepts for complex engine configurations.

    1980-03-01

    The State Energy Conservation Program was established in 1975 to promote energy conservation and to help states develop and implement their own conservation programs. Base (5) and supplemental (3) programs required states to implement programs including: mandatory thermal-efficiency standards and insulation requirements for new and renovated buildings; mandatory lighting efficiency standards for public buildings; mandatory standards and policies affecting the procurement practices of the state and its political subdivisions; program measures to promote the availability and use of carpools, vanpools, and public transportation; a traffic law or regulation which permits a right turn-on-red; and procedures to carry out a continuing public education effort to increase awareness of energy conservation; procedures which promote effective coordination among local, state, and Federal energy conservation programs; and procedures for carrying out energy audits on buildings and industrial plants. All 50 states and Puerto Rico, Guam, the Virgin Islands, American Samoa, and the District of Columbia participated in the program. The total 1980 energy savings projected by the states is about 5.9 quadrillion Btu's or about 7% of the DOE projected 1980 baseline consumption of just under 83 quads. The detailed summary is presented on the following: information the SECP evaluation; DOE response to the SECP; DOE's role in the program management process; the effectiveness of the states in managing the SECP; the status of program measure implementation; innovative state energy conservation programs; and the evaluation methodology.

    2016-01-01

    Local health department (LHD) vector control programs have experienced reductions in funding and capacity. Acknowledging this situation and its potential effect on the ability to respond to vector-borne diseases, the U.S. Centers for Disease Control and Prevention and the Public Health Foundation partnered on a performance management initiative for LHD vector control programs. The initiative involved 14 programs that conducted a performance assessment using the Environmental Public Health Performance Standards. The programs, assisted by quality improvement (QI) experts, used the assessment results to prioritize improvement areas that were addressed with QI projects intended to increase effectiveness and efficiency in the delivery of services such as responding to mosquito complaints and educating the public about vector-borne disease prevention. This article describes the initiative as a process LHD vector control programs may adapt to meet their performance management needs. This study also reviews aggregate performance assessment results and QI projects, which may reveal common aspects of LHD vector control program performance and priority improvement areas. LHD vector control programs interested in performance assessment and improvement may benefit from engaging in an approach similar to this performance management initiative.

    Abraham, Jean Marie; Crespin, Daniel J; Rothman, Alexander J

    2015-09-01

    To investigate the initiation and maintenance of participation in an employer-based wellness program that provides financial incentives for fitness center utilization. Using multivariate analysis, we investigated how employees' demographics, health status, exercise-related factors, and lifestyle change preferences affect program participation. Forty-two percent of eligible employees participated in the program, and 24% earned a $20 incentive at least once by utilizing a gym eight times or more in a month. On average, participants utilized fitness centers 7.0 months each year and earned credit 4.5 months. Participants' utilization diminished after their first year in the program. Factors associated with initiation and maintenance of fitness center utilization were similar. Declining utilization over time raises concern about the long-run effectiveness of fitness-focused wellness programs. Employers may want to consider additional levers to positively reinforce participation.

    Liang, Changwei; Wu, You; Zuo, Lei

    2016-09-01

    A novel electromagnetic pendulum energy harvester with mechanical motion rectifier (MMR) is proposed and investigated in this paper. MMR is a mechanism which rectifies the bidirectional swing motion of the pendulum into unidirectional rotation of the generator by using two one-way clutches in the gear system. In this paper, two prototypes of pendulum energy harvester with MMR and without MMR are designed and fabricated. The dynamic model of the proposed MMR pendulum energy harvester is established by considering the engagement and disengagement of the one way clutches. The simulation results show that the proposed MMR pendulum energy harvester has a larger output power at high frequencies comparing with non-MMR pendulum energy harvester which benefits from the disengagement of one-way clutch during pendulum vibration. Moreover, the proposed MMR pendulum energy harvester is broadband compare with non-MMR pendulum energy harvester, especially when the equivalent inertia is large. An experiment is also conducted to compare the energy harvesting performance of these two prototypes. A flywheel is attached at the end of the generator to make the disengagement more significant. The experiment results also verify that MMR pendulum energy harvester is broadband and has a larger output power at high frequency over the non-MMR pendulum energy harvester.

  9. The Father Friendly Initiative within Families: Using a logic model to develop program theory for a father support program.

    Gervais, Christine; de Montigny, Francine; Lacharité, Carl; Dubeau, Diane

    2015-10-01

    The transition to fatherhood, with its numerous challenges, has been well documented. Likewise, fathers' relationships with health and social services have also begun to be explored. Yet despite the problems fathers experience in interactions with healthcare services, few programs have been developed for them. To explain this, some authors point to the difficulty practitioners encounter in developing and structuring the theory of programs they are trying to create to promote and support father involvement (Savaya, R., & Waysman, M. (2005). Administration in Social Work, 29(2), 85), even when such theory is key to a program's effectiveness (Chen, H.-T. (2005). Practical program evaluation. Thousand Oaks, CA: Sage Publications). The objective of the present paper is to present a tool, the logic model, to bridge this gap and to equip practitioners for structuring program theory. This paper addresses two questions: (1) What would be a useful instrument for structuring the development of program theory in interventions for fathers? (2) How would the concepts of a father involvement program best be organized? The case of the Father Friendly Initiative within Families (FFIF) program is used to present and illustrate six simple steps for developing a logic model that are based on program theory and demonstrate its relevance.

    Intensifying detection of tuberculosis (TB) symptomatic patients is a priority for Cambodia's National Tuberculosis Program, in a country where two-thirds of the population has latent TB infection. In 2005, the National Tuberculosis Program initiated a public-private mix (PPM) collaborative program with external and local stakeholders to identify and refer persons with TB symptoms from private sector pharmacies to public sector clinics for diagnosis and treatment. This qualitative study conducted in-depth interviews with organizational stakeholders to assess their perceptions of PPM program collaboration and its sustainability in the long term. Results showed that stakeholders perceived that collaboration and efficient management had contributed to positive program performance. However, stakeholders expressed anxiety over program sustainability should external resources be reduced. Recent developments in pharmacy undergraduate education and recognition of pharmacy providers' contribution to public health interventions may challenge PPM stakeholders to shift the paradigm from dependence on external agencies to confidence in local expertise and infrastructure. © 2013 APJPH.

    2017-12-12

    A passive, linear arrangement of a sonic crystal-based apparatus and method including a 1D sonic crystal, a nonlinear medium, and an acoustic low-pass filter, for permitting unidirectional broadband ultrasound propagation as a collimated beam for underwater, air or other fluid communication, are described. The signal to be transmitted is first used to modulate a high-frequency ultrasonic carrier wave which is directed into the sonic crystal side of the apparatus. The apparatus processes the modulated signal, whereby the original low-frequency signal exits the apparatus as a collimated beam on the side of the apparatus opposite the sonic crystal. The sonic crystal provides a bandpass acoustic filter through which the modulated high-frequency ultrasonic signal passes, and the nonlinear medium demodulates the modulated signal and recovers the low-frequency sound beam. The low-pass filter removes remaining high-frequency components, and contributes to the unidirectional property of the apparatus.

    Colorectal cancer is the third most frequently diagnosed cancer worldwide. Prevention of colorectal cancer initiation represents the most effective overall strategy to reduce its associated morbidity and mortality. Activating KRAS mutation (KRASmut) is the most prevalent oncogenic driver in colorectal cancer development, and KRASmut inhibition represents an unmet clinical need. We apply a systems-level approach to study the impact of KRASmut on stem cell signaling during human colon cancer initiation by performing gene set enrichment analysis on gene expression from human colon tissues. We find that KRASmut imposes the embryonic stem cell-like program during human colon cancer initiation from colon adenoma to stage I carcinoma. Expression of miR145, an embryonic SC program inhibitor, promotes cell lineage differentiation marker expression in KRASmut colon cancer cells and significantly suppresses their tumorigenicity. Our data support an in vivo plasticity model of human colon cancer initiation that merges the intrinsic stem cell properties of aberrant colon stem cells with the embryonic stem cell-like program induced by KRASmut to optimize malignant transformation. Inhibition of the embryonic SC-like program in KRASmut colon cancer cells reveals a novel therapeutic strategy to programmatically inhibit KRASmut tumors and prevent colon cancer.

    Corporate community initiatives (CCI) are often established via cross-sector partnerships with nonprofit agencies to address critical social problems. While there is a growing body of literature exploring the effectiveness and social impact of these partnerships, there is a limited evaluative research on the implementation and execution processes of CCIs. In this paper, we examined the implementation and operational processes in the delivery of a professional sport organization's CCI initiative using program theory evaluation. The findings showed discrepancies between the associate organization and the implementers regarding understanding and fulfilling responsibilities with performing certain aspects (maintaining accurate records and program marketing) of the service delivery protocol. Despite program stakeholders being satisfied overall with the program delivery, contradictions between program stakeholders' satisfaction in the quality of program delivery was found in critical components (marketing and communications) of the service delivery. We conclude that ongoing evaluations are necessary to pinpoint the catalyst of the discrepancies along with all partners valuing process evaluation in addition to outcome evaluation.

    Many adolescents have poor mental health literacy, stigmatising attitudes towards people with mental illness, and lack skills in providing optimal Mental Health First Aid to peers. These could be improved with training to facilitate better social support and increase appropriate help-seeking among adolescents with emerging mental health problems. teen Mental Health First Aid (teen MHFA), a new initiative of Mental Health First Aid International, is a 3 × 75 min classroom based training program for students aged 15-18 years. An uncontrolled pilot of the teen MHFA course was undertaken to examine the feasibility of providing the program in Australian secondary schools, to test relevant measures of student knowledge, attitudes and behaviours, and to provide initial evidence of program effects. Across four schools, 988 students received the teen MHFA program. 520 students with a mean age of 16 years completed the baseline questionnaire, 345 completed the post-test and 241 completed the three-month follow-up. Statistically significant improvements were found in mental health literacy, confidence in providing Mental Health First Aid to a peer, help-seeking intentions and student mental health, while stigmatising attitudes significantly reduced. teen MHFA appears to be an effective and feasible program for training high school students in Mental Health First Aid techniques. Further research is required with a randomized controlled design to elucidate the causal role of the program in the changes observed.

    2009-06-01

    Full Text Available The principal-subordinate hierarchical multi-objective programming model of initial water rights allocation was developed based on the principle of coordinated and sustainable development of different regions and water sectors within a basin. With the precondition of strictly controlling maximum emissions rights, initial water rights were allocated between the first and the second levels of the hierarchy in order to promote fair and coordinated development across different regions of the basin and coordinated and efficient water use across different water sectors, realize the maximum comprehensive benefits to the basin, promote the unity of quantity and quality of initial water rights allocation, and eliminate water conflict across different regions and water sectors. According to interactive decision-making theory, a principal-subordinate hierarchical interactive iterative algorithm based on the satisfaction degree was developed and used to solve the initial water rights allocation model. A case study verified the validity of the model.

    2012-05-01

    Planarians are capable of regenerating any missing body part and present an attractive system for molecular investigation of regeneration initiation. The gene activation program that occurs at planarian wounds to coordinate regenerative responses remains unknown. We identified a large set of wound-induced genes during regeneration initiation in planarians. Two waves of wound-induced gene expression occurred in differentiated tissues. The first wave includes conserved immediate early genes. Many second-wave genes encode conserved patterning factors required for proper regeneration. Genes of both classes were generally induced by wounding, indicating that a common initial gene expression program is triggered regardless of missing tissue identity. Planarian regeneration uses a population of regenerative cells (neoblasts), including pluripotent stem cells. A class of wound-induced genes was activated directly within neoblasts, including the Runx transcription factor-encoding runt-1 gene. runt-1 was required for specifying different cell types during regeneration, promoting heterogeneity in neoblasts near wounds. Wound-induced gene expression in neoblasts, including that of runt-1, required SRF (serum response factor) and sos-1. Taken together, these data connect wound sensation to the activation of specific cell type regeneration programs in neoblasts. Most planarian wound-induced genes are conserved across metazoans, and identified genes and mechanisms should be important broadly for understanding wound signaling and regeneration initiation.

    1983-01-01

    A broadband data communications network has been implemented at BNL for control of the Alternating Gradient Synchrotron (AG) proton accelerator, using commercial CATV hardware, dual coaxial cables as the communications medium, and spanning 2.0 km. A 4 MHz bandwidth Digital Control channel using CSMA-CA protocol is provided for digital data transmission, with 8 access nodes available over the length of the RELWAY. Each node consists of an rf modem and a microprocessor-based store-and-forward message handler which interfaces the RELWAY to a branch line implemented in GPIB. A gateway to the RELWAY control channel for the (preexisting) AGS Computerized Accelerator Operating system has been constructed using an LSI-11/23 microprocessor as a device in a GPIB branch line. A multilayer communications protocol has been defined for the Digital Control Channel, based on the ISO Open Systems Interconnect layered model, and a RELWAY Device Language defined as the required universal language for device control on this channel

  10. Heterogeneous broadband network

    1995-11-01

    Although the vision for the future Integrated Broadband Communication Network (IBCN) is an all optical network, it is certain that for a long period to come, the network will remain very heterogeneous, with a mixture of different physical media (fiber, coax and twisted pair), transmission systems (PDH, SDH, ADSL) and transport protocols (TCP/IP, AAL/ATM, frame relay). In the current work towards the IBCN, the ATM concept is considered the generic network protocol for both public and private network, with the ability to use different underlying transmission protocols and, through adaptation protocols, provide the appropriate services (old as well as new) to the customer. One of the major difficulties of heterogeneous network is the restriction that is usually given by the lowest common denominator, e.g. in terms of single channel capacity. A possible way to overcome these limitations is by extending the ATM concept with a multilink capability, that allows us to use separate resources as one common. The improved flexibility obtained by this protocol extension further allows a real time optimization of network and call configuration, without any impact on the quality of service seen from the user. This paper describes an example of an ATM based multilink protocol that has been experimentally implemented within the RACE project 'STRATOSPHERIC'. The paper outlines the complexity of introducing an extra network functionality compared with the added value, such as an improved ability to recover an error due to a malfunctioning network component.

  11. Broadband transmission EPR spectroscopy.

    Directory of Open Access Journals (Sweden)

    Wilfred R Hagen

    Full Text Available EPR spectroscopy employs a resonator operating at a single microwave frequency and phase-sensitive detection using modulation of the magnetic field. The X-band spectrometer is the general standard with a frequency in the 9-10 GHz range. Most (biomolecular EPR spectra are determined by a combination of the frequency-dependent electronic Zeeman interaction and a number of frequency-independent interactions, notably, electron spin - nuclear spin interactions and electron spin - electron spin interactions, and unambiguous analysis requires data collection at different frequencies. Extant and long-standing practice is to use a different spectrometer for each frequency. We explore the alternative of replacing the narrow-band source plus single-mode resonator with a continuously tunable microwave source plus a non-resonant coaxial transmission cell in an unmodulated external field. Our source is an arbitrary wave digital signal generator producing an amplitude-modulated sinusoidal microwave in combination with a broadband amplifier for 0.8-2.7 GHz. Theory is developed for coaxial transmission with EPR detection as a function of cell dimensions and materials. We explore examples of a doublet system, a high-spin system, and an integer-spin system. Long, straigth, helical, and helico-toroidal cells are developed and tested with dilute aqueous solutions of spin label hydroxy-tempo. A detection limit of circa 5 µM HO-tempo in water at 800 MHz is obtained for the present setup, and possibilities for future improvement are discussed.

    2018-05-01

    Transition into undergraduate education programs is stressful and impacts students' well-being and academic achievement. Previous research indicates nursing students experience stress, depression, anxiety, and poor lifestyle habits which interfere with learning. However, nursing students' experience of transition into nursing programs has not been well studied. Incongruence exists between this lack of research and the desire to foster student success. This study analyzed students' experiences of initial transition into a nursing program. An embedded mixed method design. A single site of a direct-entry, four year baccalaureate Canadian nursing program. All first year nursing students enrolled in the fall term of 2016. This study combined the Student Adaptation to College Questionnaire (SACQ) with a subset of participants participating in qualitative focus groups. Quantitative data was analyzed using descriptive statistics to identify statistically significant differences in full-scale and subscale scores. Qualitative data was analyzed utilizing thematic analysis. Significant differences were seen between those who moved to attend university and those who did not, with those who moved scoring lower on the Academic Adjustment subscale. Focus group thematic analysis highlighted how students experienced initial transition into a baccalaureate nursing program. Identified themes included reframing supports, splitting focus/finding focus, negotiating own expectations, negotiating others' expectations, and forming identity. These findings form the Undergraduate Nursing Initial Transition (UNIT) Framework. Significance of this research includes applications in faculty development and program supports to increase student success in the first year of nursing and to provide foundational success for ongoing nursing practice.

    2016-01-01

    The unique properties of narrowband and broadband terahertz Bessel beams have led to a number of their applications in different fields, for example, for the depth of focusing and resolution enhancement in terahertz imaging. However, broadband terahertz Bessel beams can probably be also used for the diffraction minimization in the short-range broadband terahertz communications. For this purpose, the study of spatial-temporal dynamics of the broadband terahertz Bessel beams is needed. Here we present a simulation-based study of the propagating in non-dispersive medium broadband Bessel beams generated by a conical axicon lens. The algorithm based on scalar diffraction theory was used to obtain the spatial amplitude and phase distributions of the Bessel beam in the frequency range from 0.1 to 3 THz at the distances 10-200 mm from the axicon. Bessel beam field is studied for the different spectral components of the initial pulse. The simulation results show that for the given parameters of the axicon lens one can obtain the Gauss-Bessel beam generation in the spectral range from 0.1 to 3 THz. The length of non-diffraction propagation for a different spectral components was measured, and it was shown that for all spectral components of the initial pulse this length is about 130 mm.

    2015-09-07

    Lean as a management system has been increasingly adopted in health care settings in an effort to enhance quality, capacity and safety, while simultaneously containing or reducing costs. The Ministry of Health in the province of Saskatchewan, Canada has made a multi-million dollar investment in Lean initiatives to create "better health, better value, better care, and better teams", affording a unique opportunity to advance our understanding of the way in which Lean philosophy, principles and tools work in health care. In order to address the questions, "What changes in leadership practices are associated with the implementation of Lean?" and "When leadership practices change, how do the changed practices contribute to subsequent outcomes?", we used a qualitative, multi-stage approach to work towards developing an initial realist program theory. We describe the implications of realist assumptions for evaluation of this Lean initiative. Formal theories including Normalization Process Theory, Theories of Double Loop and Organization Leaning and the Theory of Cognitive Dissonance help understand this initial rough program theory. Data collection included: key informant consultation; a stakeholder workshop; documentary review; 26 audiotaped and transcribed interviews with health region personnel; and team discussions. A set of seven initial hypotheses regarding the manner in which Lean changes leadership practices were developed from our data. We hypothesized that Lean, as implemented in this particular setting, changes leadership practices in the following ways. Lean: a) aligns the aims and objectives of health regions; b) authorizes attention and resources to quality improvement and change management c) provides an integrated set of tools for particular tasks; d) changes leaders' attitudes or beliefs about appropriate leadership and management styles and behaviors; e) demands increased levels of expertise, accountability and commitment from leaders; f) measures and

    This book examines the reasons why various groups around the world choose not to adopt broadband services and evaluates strategies to stimulate the demand that will lead to increased broadband use. It introduces readers to the benefits of higher adoption rates while examining the progress that developed and emerging countries have made in stimulating broadband demand. By relying on concepts such as a supply and demand gap, broadband price elasticity, and demand promotion, this book explains differences between the fixed and mobile broadband demand gap, introducing the notions of substitution and complementarity between both platforms. Building on these concepts, ‘Driving Demand for Broadband Networks and Services’ offers a set of best practices and recommendations aimed at promoting broadband demand.  The broadband demand gap is defined as individuals and households that could buy a broadband subscription because they live in areas served by telecommunications carriers but do not do so because of either ...

    Patient portals have shown potential for increasing health care quality and efficiency. Internet access and other factors influencing patient portal use could worsen health disparities. Observational study of adults with 1 or more visits to the outpatient clinics of an urban public health care system from 2012 to 2015. We used mixed effects logistic regression to evaluate the association between broadband internet access and (1) patient portal initiation (whether a patient logged in at least 1 time) and (2) messaging, controlling for demographic and neighborhood characteristics. There were 243 248 adults with 1 or more visits during 2012-2015 and 70 835 (29.1%) initiated portal use. Portal initiation was 34.1% for whites, 23.4% for blacks, and 23.8% for Hispanics, and was lower for Medicaid (26.5%), Medicare (23.4%), and uninsured patients (17.4%) than commercially insured patients (39.3%). In multivariate analysis, both initiation of portal use (odds ratio [OR] = 1.24 per quintile, 95% confidence interval [CI], 1.23-1.24, P  internet access. The majority of adults with outpatient visits to a large urban health care system did not use the patient portal, and initiation of use was lower for racial and ethnic minorities, persons of lower socioeconomic status, and those without neighborhood broadband internet access. These results suggest the emergence of a digital divide in patient portal use. Given the scale of investment in patient portals and other internet-dependent health information technologies, efforts are urgently needed to address this growing inequality. © The Author 2017.

    Results for single- and multi-bunch instabilities can be significantly affected by the precise model that is used for the broadband impendance. This paper discusses three aspects of broadband impendance modeling. The first is an observation of the effect that a seemingly minor change in an impedance model has on the single-bunch mode coupling threshold. The second is a successful attempt to construct a model for the high-frequency tails of an r.f cavity. The last is a discussion of requirements for the mathematical form of an impendance which follow from the general properties of impendances

    The capability to detect optical signals over a broad wavelength band is highly important for practical device applications. However, high speed responsive across entire wavelength band within a single photodetector remains challenge. Here we demonstrated a broadband photodetector using a single quantum-dot-doped polyaniline nanowire with a broadband responsive at 350-700 nm (see schematic). The high responsivity is attributed to the high density of trapping states at the enormous interfaces formed in polyaniline and quantum dots. The interface trapping can effectively reduce the recombination rate, promote the separation of photogenerated carriers, and then enhance the efficiency for optical detection.

  4. Heavy-Section Steel Technology Program: Recent developments in crack initiation and arrest research

    Technology for the analysis of crack initiation and arrest is central to the reactor pressure vessel fracture-margin-assessment process. Regulatory procedures for nuclear plants utilize this technology to assure the retention of adequate fracture-prevention margins throughout the plant operating license period. As nuclear plants age and regulatory procedures dictate that fracture-margin assessments be performed, interest in the fracture-mechanics technology incorporated into those procedures has heightened. This has led to proposals from a number of sources for development and refinement of the underlying crack-initiation and arrest-analysis technology. This paper presents an overview of ongoing Heavy-Section Steel Technology (HSST) Program research aimed at refining the fracture toughness data used in the analysis of fracture margins under pressurized-thermal-shock loading conditions. 33 refs., 13 figs

    To acquire, improve, and pass on expertise in the operating room and at the bedside is the essential mission of the neurosurgeon. However, this is not sufficient. Learning scientific reasoning with an eye turned to applied research is the key to continually evolving neurosurgery, which should occur in close interaction with the dynamics of the fundamental neurosciences. The current reorganization of the education program should make this official and budget a systematic initiation to research during training, essential for the future of French neurosurgery.

  7. Fluctuations of quasars and other astronomical sources: final report on New Research Initiatives Program W-210

    New Research Initiatives Program W-210 produced a number of scientific results, publications, colloquia, and talks. Investigations under this program dealt with power spectra of fluctuating light sources, the apparent expansion rates of astronomical sources exploding at relativistic speed, the limits on fluctuation rates of such expanding (and nonexpanding) light sources, and related matters. Probably the most important result was a study of the time history of such an exploding light source, which showed that a widely held belief that unusually rapid fluctuations of light output would be produced in this case is not correct. This result has an important bearing on the interpretation of the redshifts of quasars and BL Lac objects, indicating that cosmological distance is very difficult to reconcile with the observations of rapid variations of luminosity. These results, and the power-spectrum results, are also of considerable interest in the study of astronomical x-ray sources. A list of publications is included

    The promotion of physical activity and health has become a universal challenge. The Sotkamo Physical Activity as Civil Skill Program was implemented to increase students' physical activity by promoting supportive psychological and physical school environment. The aim of this study was to evaluate the effectiveness of the school-initiated physical activity program on secondary school students' self-reported physical activity. The sample included 847 students (experimental condition school = 208, control school = 639) at the age of 12 to 14 years from northeast and central Finland. The program was conducted across 1 academic year and 2 measurement phases were carried out using self-report questionnaires in April 2011 and 2012. The findings highlighted that the program appeared to be effective as an approach to change the sharp decline in the pattern of Grade 7 students' self-reported physical activity across 1 school year. Specifically, change in the experimental condition students' self-reported physical activity was 13.4% higher compared the students in the control condition. On the basis of current findings, increased opportunities for school day physical activities have the potential to affect large number of students and are an efficient strategy for promoting regular physical activity. © 2015, American School Health Association.

    Family caregivers of older adults with progressive dementia (e.g., Alzheimer's disease) are confronted with a variety of challenges in providing assistance to their loved ones, such as dealing with persistent, repetitive questions, managing episodes of agitation and aggressive responding, as well as monitoring hygiene and self-care activities. Although professional and governmental organizations have called for the creation of community-based education and support programs, a significant proportion of dementia caregivers in the United States continue to receive little or no formal instruction in responding effectively to these anxiety-provoking situations. This paper describes the development and implementation of Alzheimer's Caregiver Support Online (also known as AlzOnline), an Internet- and telephone-based education and support network for caregivers of individuals with progressive dementia. An outcome analysis of a Robert Wood Johnson Foundation-funded strategic marketing initiative to promote the use of AlzOnline is reviewed, followed by a presentation of the findings of an initial program evaluation. Finally, future directions for online caregiver evaluation research are proposed.

    Short-term results have shown that transanal total mesorectal excision is safe and effective for patients with mid to low rectal cancers. Transanal total mesorectal excision is considered technically challenging; thus, adoption has been limited to a few academic centers in the United States. The aim of this study is to describe outcomes after the initiation of a transanal total mesorectal excision program in the setting of an academic colorectal training program. This is a single-center retrospective review of consecutive patients who underwent transanal total mesorectal excision from December 2014 to August 2016. This study was conducted at an academic center with a colorectal residency program. Patients with benign and malignant diseases were selected. All transanal total mesorectal excisions were performed with abdominal and perineal teams working simultaneously. The primary outcomes measured were pathologic quality, length of hospital stay, 30-day morbidity, and 30-day mortality. There were 40 patients (24 male). The median age was 55 years (interquartile range, 46.7-63.4) with a median BMI of 29 kg/m (interquartile range, 24.6-32.4). The primary indication was cancer (n = 30), and tumor height from the anal verge ranged from 0.5 to 15 cm. Eighty percent (n = 24) of the patients who had rectal cancer received preoperative chemoradiation. The most common procedures were low anterior resection (67.5%), total proctocolectomy (15%), and abdominoperineal resection (12.5%). Median operative time was 380 minutes (interquartile range, 306-454.4), with no change over time. For patients with malignancy, the mesorectum was complete or nearly complete in 100% of the specimens. A median of 14 lymph nodes (interquartile range, 12-17) were harvested, and 100% of the rectal cancer specimens achieved R0 status. Median length of stay was 4.5 days (interquartile range, 4-7), and there were 6 readmissions (15%). There were no deaths or intraoperative complications. This study

    This Special Issue of AIDS Research and Human Retroviruses features results from the HIV Cure Initiative, funded by the California HIV/AIDS Research Program (CHRP). As a publicly funded grant maker, CHRP has served for more than three decades as a unique resource for innovative researchers in California, whose work seeks to address all aspects of the HIV epidemic and the communities affected by it. Early initiatives at CHRP pioneered what would become enduring cornerstones of HIV science: isolation of the virus; efficacy and toxicities of the first HIV treatments; the emergence of drug resistance; the first biospecimen banks for HIV-related research; the first community-based laboratory service for HIV diagnostic serology; and the first longitudinal case-control study of progression from HIV to AIDS-The San Francisco General Hospital Cohort. More recently, CHRP-funded conceptual studies of zinc-finger nuclease-mediated disruption of CCR5 genomic sequences and the safety of solid organ transplantation for HIV-positive patients have progressed from brilliant ideas to clinical realities, and CHRP is currently funding the first multisite trial of HIV preexposure prophylaxis for transgender persons in the United States. The present article outlines the founding of CHRP, our current grantmaking process, and our impact on HIV research over time. In 2013, CHRP launched a new initiative aimed at moving the then nascent frontier of HIV cure science forward: the CHRP HIV Cure Initiative provided over $1.4 million to multiple basic biomedical research projects, and selected results are presented in this Special Issue.

    The scientific evidences show that the content, baking methods, and types of bread can make health impacts. Bread, as a major part of Iranian diet, demonstrates a significant potential to be targeted as health promotion subject. Healthy Food for Healthy Communities (HFHC) was a project of Isfahan Healthy Heart Program (IHHP), consisting of a wide variety of strategies, like Healthy Bread (HB) Initiative. The HB Initiative was designed to improve the behaviour of both producers and consumers, mainly aiming at making high-fibre, low-salt bread, eliminating the use of baking soda, providing enough rest time for dough before baking (at least one hour), and enough baking time (at least one minute in oven). A workshop was held for volunteer bakers, and a baker-to-baker training protocol under direct supervision was designed for future volunteers. Cereal Organization was persuaded to provide less refined flour that contained more bran. Health messages in support of new breads were disseminated by media and at bakeries by health professionals. Evaluation of the HB Initiative was done using before-after assessments and population surveys. While HB was baked in 1 (0.01%) bakery at baseline, 402 (41%) bakeries in the intervention area joined the HB Initiative in 2009. Soda was completely eliminated and fibre significantly increased from 4 +/- 0.4 g% before study to 12 +/- 0.6 g% after the intervention (p < 0.001). The preparation and baking times remarkably increased. Wastage of bread decreased from 13 +/- 1.8 g% to 2 +/- 0.5 g% and was expressed as the most important advantage of this initiative by consumers. People who lived in Isfahan city consumed whole bread 6 times more than those who lived in reference area Arak (p < 0.001). The HB Initiative managed to add new breads as a healthy choice that were compatible with local dishes and made a model to solve the longstanding problems of bread. It used various health promotion approaches but was best consistent with Beattie

    The Robert Wood Johnson Foundation Nurse Faculty Scholars (RWJF NFS) program was developed to enhance the career trajectory of young nursing faculty and to train the next generation of nurse scholars. Although there are publications that describe the RWJF NFS, no evaluative reports have been published. The purpose of this study was to evaluate the first three cohorts (n = 42 scholars) of the RWJF NFS program. A descriptive research design was used. Data were derived from quarterly and annual reports, and a questionnaire (seven open-ended questions) was administered via Survey Monkey Inc. (Palo Alto, CA, USA). During their tenure, scholars had on average six to seven articles published, were teaching/mentoring at the graduate level (93%), and holding leadership positions at their academic institutions (100%). Eleven scholars (26%) achieved fellowship in the American Academy of Nursing, one of the highest nursing honors. The average ratings on a Likert scale of 1 (not at all supportive) to 10 (extremely supportive) of whether or not RWJF had helped scholars achieve their goals in teaching, service, research, and leadership were 7.7, 8.0, 9.4, and 9.5, respectively. The majority of scholars reported a positive, supportive relationship with their primary nursing and research mentors; although, several scholars noted challenges in connecting for meetings or telephone calls with their national nursing mentors. These initial results of the RWJF NFS program highlight the success of the program in meeting its overall goal-preparing the next generation of nursing academic scholars for leadership in the profession.

    The Science Technology Engineering and Math Student Experiences Aboard Ships (STEMSEAS) program was created as a response to NSF's call (through GEOPATHS) for improving undergraduate STEM education and enhancing diversity in the geosciences. It takes advantage of unused berths on UNOLS ships during transits between expeditions. During its 2016 pilot year - which consisted of three transits on three different research vessels in different parts of the country, each with a slightly different focus - the program has gained significant insights into how best to create and structure these opportunities and create impact on individual students. A call for applications resulted in nearly 900 applicants for 30 available spots. Of these applicants, 32% are from minority groups underrepresented in the geosciences (Black, Hispanic, or American Indian) and 20% attend community colleges. The program was able to sail socioeconomically diverse cohorts and include women, veterans, and students with disabilities and from two- and four-year colleges. Twenty-three are underrepresented minorities, 6 attend community colleges, 5 attend an HBCU or tribal college, and many are at HSIs or other MSIs. While longer term impact assessment will have to wait, initial results and 6-month tracking for the first cohort indicate that these kinds of relatively short but intense experiences can indeed achieve significant impacts on students' perception of the geosciences, in their understanding of STEM career opportunities, their desire to work in a geoscience lab setting, and to incorporate geosciences into non-STEM careers. Insights were also gained into the successful makeup of mentor/leader groups, factors to consider in student selection, necessary pre- and post-cruise logistics management, follow-up activities, structure of activities during daily life at sea, increasing student networks and access to mentorships, and leveraging of pre-existing resources and ship-based opportunities

    Recently, an interdisciplinary group of faculty from the University of Idaho was awarded a major internal grant for their project "Water of the West (WoW)" to launch an interdisciplinary Water Resources Graduate Education Program. This Water Resources program will facilitate research and education to influence both the scientific understanding of the resource and how it is managed, and advance the decision-making processes that are the means to address competing societal values. By educating students to integrate environmental sciences, socio-economic, and political issues, the WoW project advances the University's land grant mission to promote economic and social development in the state of Idaho. This will be accomplished through novel experiential interdisciplinary education activities; creation of interdisciplinary research efforts among water resources faculty; and focusing on urgent regional problems with an approach that will involve and provide information to local communities. The Water Resources Program will integrate physical and biological sciences, social science, law, policy and engineering to address problems associated with stewardship of our scarce water resources. As part of the WoW project, faculty will: (1) develop an integrative problem-solving framework; (2) develop activities to broaden WR education; (3) collaborate with the College of Law to offer a concurrent J.D. degree, (4) develop a virtual system of watersheds for teaching and research, and (5) attract graduate students for team-based education. The new program involves 50 faculty from six colleges and thirteen departments across the university. This university-wide initiative is strengthened by collaboration with the Idaho Water Resources Research Institute, and participation from off-campus Centers in Idaho Falls, Boise, Twin Falls, and Coeur d'Alene. We hope this presentation will attract university faculty, water resources professionals, and others for stimulating discussions on

    The visible light broadband perfect absorbers based on the silver (Ag) nano elliptical disks and holes array are studied using finite difference time domain simulations. The semiconducting indium silicon dioxide thin film is introduced as the space layer in this sandwiched structure. Utilizing the asymmetrical geometry of the structures, polarization sensitivity for transverse electric wave (TE)/transverse magnetic wave (TM) and left circular polarization wave (LCP)/right circular polarization wave (RCP) of the broadband absorption are gained. The absorbers with Ag nano disks and holes array show several peaks absorbance of 100% by numerical simulation. These simple and flexible perfect absorbers are particularly desirable for various potential applications including the solar energy absorber.

    Interoperability and data-exchange are critical for the survival of government information management programs. E-government initiatives are transforming the way the government interacts with the public. More information is to be made available through web-enabled technologies. Programs such as the NASA's Scientific and Technical Information (STI) Program Office are tasked to find more effective ways to disseminate information to the public. The NASA STI Program is an agency-wide program charged with gathering, organizing, storing, and disseminating NASA-produced information for research and public use. The program is investigating the use of a new protocol called the Open Archives Initiative (OAI) as a means to improve data interoperability and data collection. OAI promotes the use of the OAI harvesting protocol as a simple way for data sharing among repositories. In two separate initiatives, the STI Program is implementing OAI In collaboration with the Air Force, Department of Energy, and Old Dominion University, the NASA STI Program has funded research on implementing the OAI to exchange data between the three organizations. The second initiative is the deployment of OAI for the NASA technical report server (TRS) environment. The NASA TRS environment is comprised of distributed technical report servers with a centralized search interface. This paper focuses on the implementation of OAI to promote interoperability among diverse data repositories.

    The robotic surgical platform is being utilized by a growing number of hospitals across the country, including academic medical centers. Training programs are tasked with teaching their residents how to utilize this technology. To this end, we have developed and implemented a robotic surgical curriculum, and share our initial experience here. Our curriculum was implemented for all General Surgical residents for the academic year 2014-2015. The curriculum consisted of online training, readings, bedside training, console simulation, participating in ten cases as bedside first assistant, and operating at the console. 20 surgical residents were included. Residents were provided the curriculum and notified the department upon completion. Bedside assistance and operative console training were completed in the operating room through a mix of biliary, foregut, and colorectal cases. During the fiscal years of 2014 and 2015, there were 164 and 263 robot-assisted surgeries performed within the General Surgery Department, respectively. All 20 residents completed the online and bedside instruction portions of the curriculum. Of the 20 residents trained, 13/20 (65 %) sat at the Surgeon console during at least one case. Utilizing this curriculum, we have trained and incorporated residents into robot-assisted cases in an efficient manner. A successful curriculum must be based on didactic learning, reading, bedside training, simulation, and training in the operating room. Each program must examine their caseload and resident class to ensure proper exposure to this platform.

    The Strong Rural Communities Initiative (SRCI) was created to address the health needs of rural Wisconsin communities through a multifaceted partnership that included the Medical College of Wisconsin (MCW), University of Wisconsin School of Medicine and Public Health (UWSMPH), the Rural Health Development Council (RHDC), and hospitals, public health departments, and businesses in 6 rural communities in Wisconsin. The SRCI provided a broad framework of leadership to assist each of the 6 rural communities in developing and implementing new, collaborative interventions that addressed the specific health needs of the community. Separate assessments were conducted for the communities that partnered with each respective medical school and focused on the processes of community collaboration and partnership function. Assessment approaches included formative and outcome evaluation. Each community independently reported positive outcomes associated with the partnership process and various aspects of community collaboration, including the successes and health impacts of the workplace wellness programs implemented. Assessment data also revealed challenges related to conducting effective community-academic partnerships. The SRCI was established to execute statewide programs in rural communities with the goal to improve the health of people living in those communities. We have gained applicable knowledge regarding the types of challenges that exist in establishing a rural-based community research network between academic partners and community leaders.

    Safeguards by Design (SBD) is defined as the incorporation of safeguards features early in the design phase of a new nuclear facility in order to avoid the need to redesign the facility at a later date, or retrofit the completed facility. Not only can SBD avoid the need for redesign or retrofit, but consideration of safeguards features early in the facility design effort can provide for a more efficient and effective safeguards design. A program has been initiated by the United States Department of Energy during the past several years to develop, demonstrate and institutionalization SBD. This plan has been developed in parallel with a similar effort at the IAEA while taking into account their achievements and future plans. The United States SBD program is focused on (1) identification of best practices that satisfy existing safeguards requirements, (2) identification of advanced concepts where best practices can be improved, and (3) institutionalizing SBD by gaining its acceptance as a global norm for the design of new nuclear facilities. SBD guidance documents are being prepared as an aid to industry for their design activities, to describe the relationship between requirements, best practices, and advanced concepts. SBD 'lessons learned' studies have been conducted to help identify the existing best practices and potential areas for improvement. Finally, acceptance as a global norm is being pursued by way of international workshops, engagement with industry and the IAEA, and setting an example by way of its use in new nuclear facilities in the United States.

    Color vision is commonly assumed to rely on photoreceptors tuned to narrow spectral ranges. In the ommatidium of Drosophila, the four types of so-called inner photoreceptors express different narrow-band opsins. In contrast, the outer photoreceptors have a broadband spectral sensitivity and were thought to exclusively mediate achromatic vision. Using computational models and behavioral experiments, we demonstrate that the broadband outer photoreceptors contribute to color vision in Drosophila. The model of opponent processing that includes the opsin of the outer photoreceptors scored the best fit to wavelength discrimination data. To experimentally uncover the contribution of individual photoreceptor types, we restored phototransduction of targeted photoreceptor combinations in a blind mutant. Dichromatic flies with only broadband photoreceptors and one additional receptor type can discriminate different colors, indicating the existence of a specific output comparison of the outer and inner photoreceptors. Furthermore, blocking interneurons postsynaptic to the outer photoreceptors specifically impaired color but not intensity discrimination. Our findings show that receptors with a complex and broad spectral sensitivity can contribute to color vision and reveal that chromatic and achromatic circuits in the fly share common photoreceptors.

    The presence of a scientist or other STEM expert in secondary school science classroom can provide fresh new ideas for student learning. Through the Initiating New Science Partnerships in Rural Education (INSPIRE) program sponsored by NSF Graduate STEM Fellows in K-12 Education (GK-12), scientists and engineers at Mississippi State University work together with graduate students and area teachers to provide hands-on inquiry-based learning to middle school and high school students. Competitively selected graduate fellows from geosciences, physics, chemistry, and engineering spend ten hours per week in participating classrooms for an entire school year, working as a team with their assigned teacher to provide outstanding instruction in science and mathematics and to serve as positive role models for the students. We are currently in the second year of our five-year program, and we have already made significant achievements in science and mathematics instruction. We successfully hosted GIS Day on the Mississippi State University campus, allowing participating students to design an emergency response to a simulated flooding of the Mississippi Delta. We have also developed new laboratory exercises for high school physics classrooms, including a 3-D electric field mapping exercise, and the complete development of a robotics design course. Many of the activities developed by the fellows and teachers are written into formal lesson plans that are made publicly available as free downloads through our project website. All participants in this program channel aspects of their research interests and methods into classroom learning, thus providing students with the real-world applications of STEM principles. In return, participants enhance their own communication and scientific inquiry skills by employing lesson design techniques that are similar to defining their own research questions.

    In the early postwar years, beginning in 1949 and extending to the mid-1960s, U.S. Atomic Energy Commission (AEC) research on the fate and effects of radionuclides in the environment was driven by distinct environmental concerns-- the releases of radioactive materials around production sites, fallout from nuclear weapons tests, and radiation effects from both external and internal exposures. These problem areas spawned development of the scientific field of radioecology. To understand the perspectives in the 1950s of the United States on the issues of nuclear energy and the environment, we have reviewed the early research programs. Keeping to the theme of the papers in this environmental session, we will focus on the first area of concern -- the scientific studies to understand the environmental consequences of nuclear production and fuel reprocessing at the three primary production sites: the Hanford Works in the state of Washington, Clinton Laboratories in Oak Ridge, Tennessee, and the Savannah River Plant in South Carolina. The driving environmental issue was the fate and effects of waste products from nuclear fuel production and reprocessing -- concern about entry into environmental pathways. Early operational monitoring and evaluation by health physicists led to realization that additional emphasis needed to be placed on understanding environmental fate of radionuclides. What followed was forward-thinking R and D planning and development of interdisciplinary research teams for experimentation on complex environmental systems. What follows is a review of the major U.S. AEC radioecology research programs initiated during the 1950s, the issues leading to the establishment of these programs, early results, and their legacies for environmental protection and ecological research in the following decades

  12. Combination of broadband diffuse optical spectroscopy with magnetic resonance imaging

    Merritt, Sean Isaiah

    Broadband diffuse optical spectroscopy (DOS) is an emerging optical technique used to measure absorption and scattering of bulk tissue non-invasively within the near-infrared (600--1050 nm). The ultimate aim of my advisors group is for broadband DOS to become an established medical diagnostic technique used clinically on various tissue types including breast, muscle and bone. The specific goal for my research is to use established magnetic resonance (MR) techniques for the purpose of continued development and validation of broadband DOS. The initial studies carried out were a validation of broadband DOS through a direct comparison with MRI. Both techniques are sensitive to signals produced by water and lipids in tissue. There is also sensitivity to blood flow, which MRI measures using exogenous contrast agents and broadband DOS is sensitive through measurement of total hemoglobin content (THC) and tissue oxygen saturation (StO2). These validation studies were compared initially in a rat tumor model in which both techniques were used simultaneously. A qualitative correlation was found between the MR images of water content and blood perfusion compared with the DOS water and THC values. A more quantitative comparison was made between measuring absolute water and lipid content in phantoms and in human tissue, which showed a strong correlation. The in vivo study also validated that broadband DOS was interrogating bone marrow in the tibia. The second half of this thesis is focused on developing new capabilities of broadband DOS and the MRI literature is used as a guide. When a water molecule hydrogen bonds to another molecule, the absorption spectrum in the near-infrared which is due to the vibrational overtone of the OH bond will change. The expected changes were observed in tissue and an algorithm was developed to fit for a tissue bound water parameter. Also, as tissue temperature changes, the fraction of water bound to other water molecules changes and can be used to

    Key component of the Next Generation Safeguards Initiative (NGSI) launched by the National Nuclear Security Administration is the development of human capital to meet present and future challenges to the safeguards regime. An effective university-level education in safeguards and related disciplines is an essential element in a layered strategy to rebuild the safeguards human resource capacity. Two pilot programs at university level, involving 44 students, were initiated and implemented in spring-summer 2008 and linked to hands-on internships at LANL or LLNL. During the internships, students worked on specific safeguards-related projects with a designated Laboratory Mentor to provide broader exposure to nuclear materials management and information analytical techniques. The Safeguards and Nuclear Material Management pilot program was a collaboration between the Texas A and M University (TAMU), Los Alamos National Laboratory (LANL) and Lawrence Livermore National Laboratory (LLNL). It included a 16-lecture course held during a summer internship program. The instructors for the course were from LANL together with TAMU faculty and LLNL experts. The LANL-based course was shared with the students spending their internship at LLNL via video conference. A week-long table-top (or hands-on) exercise on was also conducted at LANL. The student population was a mix of 28 students from a 12 universities participating in a variety of summer internship programs held at LANL and LLNL. A large portion of the students were TAMU students participating in the NGSI pilot. The International Nuclear Safeguards Policy and Information Analysis pilot program was implemented at the Monterey Institute for International Studies (MIIS) in cooperation with LLNL. It included a two-week intensive course consisting of 20 lectures and two exercises. MIIS, LLNL, and speakers from other U.S. national laboratories (LANL, BNL) delivered lectures for the audience of 16 students. The majority of students

    2008-05-01

    The Research Scholars Program (RSP) was created at the Oregon College of Oriental Medicine (OCOM) to provide faculty development in research literacy, research-informed clinical practice, and research participation skills. The RSP is part of a broad effort, funded by a National Institutes of Health/National Center for Complementary and Alternative Medicine R25 education grant, to infuse an evidence-based perspective into the curriculum at schools of complementary and alternative medicine. The RSP arose from the realization that this curriculum reform would first necessitate faculty training in both research appreciation and pedagogy. OCOM's grant, Acupuncture Practitioner Research Education Enhancement, is a partnership with the Oregon Health & Science University School of Nursing (OHSU SON). The RSP was developed initially as a collaborative effort among the OCOM Dean of Research (R.H.), OCOM Director of Research Education (S.F.), and an OHSU SON education specialist (K.L.). The 9-month, 8 hours per month seminar-style RSP provides the opportunity for a cohort of OCOM faculty and staff to explore research-related concepts and content as well as pedagogical practices that emphasize interactive, learner-centered teaching. The RSP adheres to a competency-based approach as developed by the Education Committee of the grant. As a tangible outcome, each Research Scholar designs a sustainable learning activity that infuses a research perspective into their courses, clinic supervision, or other sphere of influence at the college. In this paper, we describe the creative process and the lessons learned during the planning and initial implementation of the RSP. We view the early successes of the RSP as encouraging signs that research literacy and an evidence-based perspective are becoming increasingly accepted as needed skill sets for present-day practitioners of acupuncture and Oriental medicine.

    2013-01-01

    The US Department of Energy Office of Environmental Management (DOE-EM) oversees one of the largest and most technically challenging cleanup programs in the world. The mission of DOE-EM is to complete the safe cleanup of the environmental legacy from five decades of nuclear weapons development and government-sponsored nuclear energy research. Since 1995, Florida International University's Applied Research Center (FIU-ARC) has supported the DOE-EM mission and provided unique research capabilities to address some of these highly technical and difficult challenges. This partnership has allowed FIU-ARC to create a unique infrastructure that is critical for the training and mentoring of science, technology, engineering, and math (STEM) students and has exposed many STEM students to 'hands-on' DOE-EM applied research, supervised by the scientists and engineers at ARC. As a result of this successful partnership between DOE and FIU, DOE requested FIU-ARC to create the DOE-FIU Science and Technology Workforce Development Initiative in 2007. This innovative program was established to create a 'pipeline' of minority STEM students trained and mentored to enter DOE's environmental cleanup workforce. The program was designed to help address DOE's future workforce needs by partnering with academic, government and private companies (DOE contractors) to mentor future minority scientists and engineers in the research, development, and deployment of new technologies and processes addressing DOE's environmental cleanup challenges. Since its inception in 2007, the program has trained and mentored 78 FIU STEM minority students. Although, the program has been in existence for only six years, a total of 75 internships have been conducted at DOE National Laboratories, DOE sites, DOE Headquarters and field offices, and DOE contractors. Over 100 DOE Fellows have participated in the Waste Management (WM) Symposia since 2008 with a total of 84 student

  18. Reactive Carbonyl Species Activate Caspase-3-Like Protease to Initiate Programmed Cell Death in Plants.

    Reactive oxygen species (ROS)-triggered programmed cell death (PCD) is a typical plant response to biotic and abiotic stressors. We have recently shown that lipid peroxide-derived reactive carbonyl species (RCS), downstream products of ROS, mediate oxidative signal to initiate PCD. Here we investigated the mechanism by which RCS initiate PCD. Tobacco Bright Yellow-2 cultured cells were treated with acrolein, one of the most potent RCS. Acrolein at 0.2 mM caused PCD in 5 h (i.e. lethal), but at 0.1 mM it did not (sublethal). Specifically, these two doses caused critically different effects on the cells. Both lethal and sublethal doses of acrolein exhausted the cellular glutathione pool in 30 min, while the lethal dose only caused a significant ascorbate decrease and ROS increase in 1-2 h. Prior to such redox changes, we found that acrolein caused significant increases in the activities of caspase-1-like protease (C1LP) and caspase-3-like protease (C3LP), the proteases which trigger PCD. The lethal dose of acrolein increased the C3LP activity 2-fold more than did the sublethal dose. In contrast, C1LP activity increments caused by the two doses were not different. Acrolein and 4-hydroxy-(E)-2-nonenal, another RCS, activated both proteases in a cell-free extract from untreated cells. H 2 O 2 at 1 mM added to the cells increased C1LP and C3LP activities and caused PCD, and the RCS scavenger carnosine suppressed their activation and PCD. However, H 2 O 2 did not activate the proteases in a cell-free extract. Thus the activation of caspase-like proteases, particularly C3LP, by RCS is an initial biochemical event in oxidative signal-stimulated PCD in plants. © The Author 2016.

    The Basin of Mexico (19°30'N, 99°W, 9600 km2, 2240 m asl) is a hydrologically-closed basin in the TransMexican Volcanic Belt. The emergence of the Chichinautzin volcanic field after ~780 ka is linked to basin closure and initiation of the development of a lake system within the basin. Continued subsidence accommodated accumulation of a long lacustrine sediment sequence. Radiocarbon chronologies indicate sedimentation rates of ~40 cm/kyr since ~40ka; application of this rate to the entire lacustrine sequence suggests a basal age of ~800 ka, consistent with the Chichinautzin volcanic age. To investigate the environmental history contained in Basin of Mexico sediments, the MexiDrill Program recovered a long lacustrine sedimentary sequence contained in the Lake Chalco basin on the southern outskirts of Mexico City. These sediments have the potential to provide a >500,000 year record of North American climate. Chalco is well suited for reconstruction and investigation of interannual through orbital-scale variations in the North American Monsoon and hydrologic variations of the neotropics. Ongoing work suggests that the system records environmental responses to both Milankovitch- and millennial-scale climate forcing.

    UCLA Health embarked to transform care by integrating lean methodology in a key clinical project, Readmission Reduction Initiative (RRI). The first step focused on assembling a leadership team to articulate system-wide priorities for quality improvement. The lean principle of creating a culture of change and accountability was established by: 1) engaging stakeholders, 2) managing the process with performance accountability, and, 3) delivering patient-centered care. The RRI utilized three major lean principles: 1) A3, 2) root cause analyses, 3) value stream mapping. Baseline readmission rate at UCLA from 9/2010-12/2011 illustrated a mean of 12.1%. After the start of the RRI program, for the period of 1/2012-6/2013, the readmission rate decreased to 11.3% (pservice- and location-based interventions into strategies with broader approach. As elucidated, a systematic clinical approach grounded in lean methodologies is a viable solution to this complex problem. Copyright © 2017 Elsevier Inc. All rights reserved.

    The aims of this retrospective, descriptive study were to describe clients served by a buprenorphine program in a community-based recovery center and to present initial treatment outcomes. A record review was conducted for clients treated from July 2010 to August 2011. Client demographic, health, substance use, and treatment history data were abstracted from the records of the first 78 clients served. Buprenorphine and opiate use data were collected via urine toxicology reports, collected weekly among clients who remained enrolled in treatment. The average percentages of weeks spent opiate free and buprenorphine compliant were 83% (SD = 26%) and 95% (SD = 13%), respectively. When positive heroin toxicology and negative buprenorphine toxicology were replaced for the missing/unknown data, the average percentages of opiate-abstinent weeks and buprenorphine compliance were 60% (SD = 34%) and 74% (SD = 28%), respectively. Roughly half of all clients (49%) were successfully transitioned to continue treatment with buprenorphine in a primary care setting. Findings from this study demonstrate that buprenorphine treatment for opiate dependence can be incorporated into a community-based recovery center with high rates of opiate abstinence and treatment adherence.

    Maternal factors initiate the zygotic developmental program in animal embryos. In embryos of the chordate, Ciona intestinalis, three maternal factors-Gata.a, β-catenin, and Zic-r.a-are required to establish three domains of gene expression at the 16-cell stage; the animal hemisphere, vegetal hemisphere, and posterior vegetal domains. Here, we show how the maternal factors establish these domains. First, only β-catenin and its effector transcription factor, Tcf7, are required to establish the vegetal hemisphere domain. Second, genes specifically expressed in the posterior vegetal domain have additional repressive cis-elements that antagonize the activity of β-catenin/Tcf7. This antagonizing activity is suppressed by Zic-r.a, which is specifically localized in the posterior vegetal domain and binds to DNA indirectly through the interaction with Tcf7. Third, Gata.a directs specific gene expression in the animal hemisphere domain, because β-catenin/Tcf7 weakens the Gata.a-binding activity for target sites through a physical interaction in the vegetal cells. Thus, repressive regulation through protein-protein interactions among the maternal transcription factors is essential to establish the first distinct domains of gene expression in the chordate embryo.

    2018-02-01

    Thermal cracking on concrete dams depends upon the rate at which the concrete is cooled (temperature drop rate per day) within an initial cooling period during the construction phase. Thus, in order to control the thermal cracking of such structure, temperature development due to heat of hydration of cement should be dropped at suitable rate. In this study, an attempt have been made to formulate the relation between cooling rate of mass concrete with passage of time (age of concrete) and water cooling parameters: flow rate and inlet temperature of cooling water. Data measured at summer season (April-August from 2009 to 2012) from recently constructed high concrete dam were used to derive a prediction model with the help of Genetic Programming (GP) software “Eureqa”. Coefficient of Determination (R) and Mean Square Error (MSE) were used to evaluate the performance of the model. The value of R and MSE is 0.8855 and 0.002961 respectively. Sensitivity analysis was performed to evaluate the relative impact on the target parameter due to input parameters. Further, testing the proposed model with an independent dataset those not included during analysis, results obtained from the proposed GP model are close enough to the real field data.

  5. The path from ITER to a power plant - initial results from the ARIES ''Pathways'' program

    Najmabadi, F.

    2007-01-01

    The US national power plant studies program, ARIES, has initiated a 3-year integrated study, called the ''Pathways Program'' to investigate what the fusion program needs to do, in addition to successful operation of the ITER, in order to transform fusion into a commercial reality. The US power industry and regulatory agencies view the demonstration power plant, DEMO, as a device which is build and operated by industry, possibly with government participation, to demonstrate the commercial readiness of fusion power. As such, the ''Pathways'' programs will investigate what is needed, in addition to successful operation of ITER, to convince industry to move forward with a fusion DEMO. While many reports exists that provide a strategic view of the needs for fusion development; in the ITER era, a much more detailed view is needed to provide the necessary information for program planning. By comparing the anticipated results from ITER and existing facilities with the requirements for a power plant in the first phase of the Pathways study, we will develop a comprehensive list of remaining R and D items for developing fusion, will identify metrics for distributing resources among R and D issues, and will identify which of those items can/should be done in existing or simulation facilities. In the second phase of the study, we will develop potential embodiments for the fusion test facility (ies) and explore their cost/performance parametrically. An important by-product of this study is the identification of key R and D issues that can be performed and resolved in existing facilities to make the fusion facility cheaper and/or a higher performance device. This paper summarizes the results from the first phase of our study. We have adopted a ''holistic'' or integrated approach with the focus on the needs of the customer. In such an approach, the remaining R and D should generate all of the information needed by industry to move forward with the DEMO, i.e., data needed to

Access can be delivered by means of many different technology solutions described in the paper. This means a greater degree of competition and affects the kind of policy measures to be applied. The paper concludes that other policy measure than the classical universal service obligation are in play, and discusses various policy measures taking the Lisbon process as a point of departure. Available policy measures listed in the paper include, universal service obligation, harmonization, demand stimulation, public support for extending the infrastructure, public private partnerships (PPP, and others.

  8. POTS to broadband ... cable modems.

    Kabachinski, Jeff

    2003-01-01

    There have been 3 columns talking about broadband communications and now at the very end when it's time to compare using a telco or cableco, I'm asking does it really matter? So what if I can actually get the whole 30 Mbps with a cable network when the website I'm connecting to is running on an ISDN line at 128 Kbps? Broadband offers a lot more bandwidth than the connections many Internet servers have today. Except for the biggest websites, many servers connect to the Internet with a switched 56-Kbps, ISDN, or fractional T1 line. Even with the big websites, my home network only runs a 10 Mbps Ethernet connection to my cable modem. Maybe it doesn't matter that the cable lines are shared or that I can only get 8 Mbps from an ADSL line. Maybe the ISP that I use has a T1 line connection to the Internet so my new ADSL modem has a fatter pipe than my provider! (See table 1). It all makes me wonder what's in store for us in the future. PC technology has increased exponentially in the last 10 years with super fast processor speeds, hard disks of hundreds of gigabytes, and amazing video and audio. Internet connection speeds have failed to keep the same pace. Instead of hundreds of times better or faster--modem speeds are barely 10 times faster. Broadband connections offer some additional speed but still not comparable growth as broadband connections are still in their infancy. Rather than trying to make use of existing communication paths, maybe we need a massive infrastructure makeover of something new. How about national wireless access points so we can connect anywhere, anytime? To use the latest and fastest wireless technology you will simply need to buy another $9.95 WLAN card or download the latest super slick WLAN compression/encryption software. Perhaps it is time for a massive infra-restructuring. Consider the past massive infrastructure efforts. The telcos needed to put in their wiring infrastructure starting in the 1870s before telephones were useful to the

    1988-01-01

    A limited number of high-priority research initiatives are recommended for early implementation as part of the U.S. contribution to the preparatory phase of the International Geosphere-Biosphere Program. The recommendations are based on the committee's analysis of the most critical gaps in the scientific knowledge needed to understand the changes that are occurring in the earth system not being addressed by existing programs. The report articulates a number of important key issues and interactions that characterize global change in the geosphere-biosphere system on time scales of decades to centuries; identifies the knowledge that is the most urgently needed to improve understanding of those issues and interactions; and formulates initial priorities for initial U.S. contributions to the IGBP, recognizing the contributions of other ongoing and proposed programs.

    The Human Capital Development (HCD) subprogram of the U.S. Next Generation Safeguards Initiative (NGSI) is developing sustainable academic and technical programs that support the recruitment, education, training, and retention of the next generation of international safeguards professionals. This wide-ranging HCD effort endeavors to develop additional human resources to address current shortfalls, encourage U.S. experts to seek employment at the IAEA, and identify and train a new cadre of safeguards experts to meet the needs of both the United States and the IAEA for decades to come. In recent years, a convergence of factors has challenged the IAEA's ability to carry out its safeguards mission effectively. A staffing study shows that less than 20% of the international safeguards specialists in the U.S. workforce are 44 years of age or younger and that over 80% of the international safeguards specialists at the National Laboratories will be retired or otherwise resigned within 15 years. An aging workforce nearing retirement and growing workload, coupled with a safeguards budget that has remained essentially flat in real terms for nearly two decades, have posed particular challenges to the IAEA's Department of Safeguards. Recognizing the trends, the National Nuclear Security Administration's (NNSA) Office of Nonproliferation and International Security (NIS) launched NGSI in the fall of 2007. Since that time, the HCD subprogram of NGSI has sponsored over 300 safeguards internships at U.S. National Labs, organized eight annual short safeguards policy and technical courses, worked with ten universities to develop new undergraduate and graduate course-work on international safeguards and nonproliferation, established a highly competitive graduate fellowship program, and completed a human capital requirements study that closely examined the safeguards workforce within the U.S. National Lab complex. Of past NGSI students and interns, nearly four in ten pursue multiple NGSI

    In FY2008, the U.S. Department of Defense (DoD) initiated the Computational Research and Engineering Acquisition Tools and Environments (CREATE) program, a $360M program with a two-year planning phase and a ten-year execution phase. CREATE will develop and deploy three computational engineering tool sets for DoD acquisition programs to use to design aircraft, ships and radio-frequency antennas. The planning and execution of CREATE are based on the 'lessons learned' from case studies of large-scale computational science and engineering projects. The case studies stress the importance of a stable, close-knit development team; a focus on customer needs and requirements; verification and validation; flexible and agile planning, management, and development processes; risk management; realistic schedules and resource levels; balanced short- and long-term goals and deliverables; and stable, long-term support by the program sponsor. Since it began in FY2008, the CREATE program has built a team and project structure, developed requirements and begun validating them, identified candidate products, established initial connections with the acquisition programs, begun detailed project planning and development, and generated the initial collaboration infrastructure necessary for success by its multi-institutional, multidisciplinary teams

    2012-07-12

    Thousands of cylinders containing uranium hexafluoride (UF{sub 6}) move around the world from conversion plants to enrichment plants to fuel fabrication plants, and their contents could be very useful to a country intent on diverting uranium for clandestine use. Each of these large cylinders can contain close to a significant quantity of natural uranium (48Y cylinder) or low-enriched uranium (LEU) (30B cylinder) defined as 75 kg {sup 235}U which can be further clandestinely enriched to produce 1.5 to 2 significant quantities of high enriched uranium (HEU) within weeks or months depending on the scale of the clandestine facility. The National Nuclear Security Administration (NNSA) Next Generation Safeguards Initiative (NGSI) kicked off a 5-year plan in April 2011 to investigate the concept of a unique identification system for UF{sub 6} cylinders and potentially to develop a cylinder tracking system that could be used by facility operators and the International Atomic Energy Agency (IAEA). The goal is to design an integrated solution beneficial to both industry and inspectorates that would improve cylinder operations at the facilities and provide enhanced capabilities to deter and detect both diversion of low-enriched uranium and undeclared enriched uranium production. The 5-year plan consists of six separate incremental tasks: (1) define the problem and establish the requirements for a unique identification (UID) and monitoring system; (2) develop a concept of operations for the identification and monitoring system; (3) determine cylinder monitoring devices and technology; (4) develop a registry database to support proof-of-concept demonstration; (5) integrate that system for the demonstration; and (6) demonstrate proof-of-concept. Throughout NNSA's performance of the tasks outlined in this program, the multi-laboratory team emphasizes that extensive engagement with industry stakeholders, regulatory authorities and inspectorates is essential to its success.

  20. Customer Churn Prediction for Broadband Internet Services

    Science.gov (United States)

    Huang, B. Q.; Kechadi, M.-T.; Buckley, B.

    Although churn prediction has been an area of research in the voice branch of telecommunications services, more focused studies on the huge growth area of Broadband Internet services are limited. Therefore, this paper presents a new set of features for broadband Internet customer churn prediction, based on Henley segments, the broadband usage, dial types, the spend of dial-up, line-information, bill and payment information, account information. Then the four prediction techniques (Logistic Regressions, Decision Trees, Multilayer Perceptron Neural Networks and Support Vector Machines) are applied in customer churn, based on the new features. Finally, the evaluation of new features and a comparative analysis of the predictors are made for broadband customer churn prediction. The experimental results show that the new features with these four modelling techniques are efficient for customer churn prediction in the broadband service field.

  6. Robust excitation power spectrum design for broadband impedance spectroscopy

    International Nuclear Information System (INIS)

    Sanchez, B; Rojas, C R

    2014-01-01

    This paper focuses on the robust design of broadband impedance spectroscopy (IS) experiments. This contribution extends the optimal IS experiment design presented in previous work (Sanchez et al 2012 Meas. Sci. Technol. 23 085702) in order to design a robust broadband excitation which gives relatively good estimation performance over a large number of possible impedance models. To this end, we assume as prior knowledge that the parameters of the impedance model lie in a compact set. Then, we pose the experiment design problem as a convex optimization program, which gives the excitation signal of bounded power that minimizes the worst value of a given scalar function of the Fisher information matrix, as the parameters range over the given compact set. Supported by numerical simulations, our results reveal the robust excitation for impedance experiments has a discrete power spectrum, e.g. (periodic) multisine signals. (paper)

    To describe the implementation of a robotic thoracic surgery program at a public tertiary teaching hospital and to analyze its initial results. This was a planned interim analysis of a randomized clinical trial aimed at comparing video-assisted thoracoscopic surgery and robotic surgery in terms of the results obtained after pulmonary lobectomy. The robotic surgery program developed at the Instituto do Câncer do Estado de São Paulo, in the city of São Paulo, Brazil, is a multidisciplinary initiative involving various surgical specialties, as well as anesthesiology, nursing, and clinical engineering teams. In this analysis, we evaluated the patients included in the robotic lobectomy arm of the trial during its first three months (from April to June of 2015). Ten patients were included in this analysis. There were eight women and two men. The mean age was 65.1 years. All of the patients presented with peripheral tumors. We performed right upper lobectomy in four patients, right lower lobectomy in four, and left upper lobectomy in two. Surgical time varied considerably (range, 135-435 min). Conversion to open surgery or video-assisted thoracoscopic surgery was not necessary in any of the cases. Intraoperative complications were not found. Only the first patient required postoperative transfer to the ICU. There were no deaths or readmissions within the first 30 days after discharge. The only postoperative complication was chest pain (grade 3), in two patients. Pathological examination revealed complete tumor resection in all cases. When there is integration and proper training of all of the teams involved, the implementation of a robotic thoracic surgery program is feasible and can reduce morbidity and mortality.

    Many developing countries have shown interest in embracing telemedicine and incorporating it into their healthcare systems. In 2000, the U.S. Army Yuma Proving Ground (YPG) initiated a program to assist the Republic of Panama in establishing a demonstration Panamanian rural telemedicine program. YPG engaged the Arizona Telemedicine Program (ATP) to participate in the development and implementation of the program. The ATP recommended adoption of a "top-down" strategy for creating the program. Early buy-in of the Panamanian Ministry of Health and academic leaders was regarded as critical to the achievement of long-term success. High-level meetings with the Minister of Health and the Rectors (i.e., Presidents) of the national universities gained early program support. A telemedicine demonstration project was established on a mountainous Indian reservation 230 miles west of Panama City. Today, three rural telemedicine clinics are linked to a regional Ministry of Health hospital for teleconsultations. Real-time bidirectional videoconferencing utilizes videophones connected over Internet protocol networks at a data rate of 768 kilobits per second to the San Felix Hospital. Telepediatrics, tele-obstetrics, telepulmonology, teledermatology, and tele-emergency medicine services became available. Telemedicine services were provided to the three sites for a total of 1,013 cases, with numbers of cases increasing each year. These three demonstration sites remained in operation after discontinuation of the U.S. involvement in September 2009 and serve as a model program for other telemedicine initiatives in Panama. Access to the assets of a partner-nation was invaluable in the establishment of the first model telemedicine demonstration program in Panama. After 3 years, the Panamanian Telemedicine and Telehealth Program (PTTP) became self-sufficient. The successful achievement of sustainability of the PTTP after disengagement by the United States fits the Latifi-Weinstein model

    To evaluate therapeutic efficacy upon augmenting the initial communication to patients regarding the diagnosis of psychogenic nonepileptic seizures (PNES) with a novel, brief group psychoeducation administered by the same team that provided the video-electroencephalography (VEEG) confirmed diagnosis and within 4 weeks of the diagnosis. Prior to discharge from the epilepsy monitoring unit (EMU), a standardized communication strategy was utilized to explain the diagnosis of PNES to all patients prior to enrollment. Enrolled patients were then randomized to either participation in three successive and monthly group psychoeducational sessions (intervention group), or routine seizure clinic follow-up visits (control group). Both groups completed questionnaires at time of enrollment, and then at approximately 3 months (follow-up 1) and 6 months (follow-up 2) after discharge, assessing for: (1) primary outcomes that include a measure of psychosocial functioning, as well as interval difference in seizure frequency/intensity; and (2) secondary outcomes that include interval seizure-related emergency room visits or hospitalizations, development of new and medically unexplained symptoms, and results of an internal measure of knowledge and perception outcomes. The majority (73%) of patients from the intervention group commenced on therapy sessions within 4 weeks after learning of the diagnosis. Although we did not observe significant group difference in seizure frequency/intensity, patients from the intervention group showed significant improvement on the Work and Social Adjustment Scale (WSAS) scores at both follow-up 1 (p = 0.013) and follow-up 2 (p = 0.038) after discharge from the EMU. In addition, we observed a trend toward lesser likelihood for seizure-related emergency room visits or hospitalizations for the intervention group (p = 0.184), as well as meaningful insights from an internal measure of intervention outcomes. These findings suggest that our cost

    Abstract Background The core elements provide a framework for nursing homes (NH) to establish antibiotic stewardship programs (ASP). We report on implementation and sustainability of ASP through a hospital-NH partnership. Methods Since 2014, a hospital-based team (HBT) assisted 9 NH in Monroe County, NY in implementing ASP. Enrollment was staggered; data are currently available from 2 NH: Facility X (470 beds, full-time medical director and Infection Preventionist (IP)) and Facility Y (288 beds, part-time medical director and IP). The HBT analyzed antibiotic data to develop initial interventions focusing on reducing urinary tract infection (UTI) treatment and quinolone use. Activities included (1) regular presentation of antibiotic days of therapy (DOT), urine culture rates and treatment appropriateness; (2) coaching on interpretation and use of data to expand interventions; (3) creation of citywide guideline for diagnosis and treatment of common infections; and (4) education of nurses, providers, and families. Results The HBT provided drug expertise and support throughout the project; however, involvement of NH staff varied. The Facility X IP assumed responsibility for the review and feedback of urine culture data and education and the medical director educated clinicians and families on treatment guidelines. Facility Y’s ASP was led by the medical director and focused mainly on education of clinicians. Facility X saw significant reductions in all metrics in 2016. Facility Y significantly reduced their quinolone use and urine culture rate; however, this did not translate into a reduction in DOT for UTI (Table 1). Table 1.

    The process of starting a new program in computer science and engineering, heavily based on applied mathematics and only open to women, is described in this paper. The program was introduced into an educational system without any tradition in single-sex education. Important observations made during the process included the considerable interest in mathematics and curiosity about computer science found among female students at the secondary school level, and the acceptance of the single-sex program by the staff, administration, and management of the university as well as among male and female students. The process described highlights the importance of preparing the environment for a totally new type of educational program.

    2015-10-01

    In 2011, a small pilot bike share program was established in the town core of Kailua, Hawai'i, with funding from the Hawai'i State Department of Health. The Kailua system consisted of two stations with 12 bicycles, and the goal was to secure additional funding to expand the station network in the future. Community feedback consistently indicated support for the bike share program. However, system metrics showed low levels of usage, averaging 41.5 rides per month (2011-2014). From observational data, users were primarily tourists. With minimal local staff, the bike share program had limited resources for promotion and education, which may have hindered potential use by local residents. Management of station operations and bike maintenance were additional, ongoing barriers to success. Despite the challenges, the pilot bike share program was valuable in several ways. It introduced the bike share concept to Hawai'i, thereby helping to build awareness and connect an initial network of stakeholders. Furthermore, the pilot bike share program informed the development of a larger bike share program for urban Honolulu. As limited information exists in the literature about the experiences of smaller bike share programs and their unique considerations, this article shares lessons learned for other communities interested in starting similar bike share programs.

    Studies have documented performance on the United States Medical Licensing Examination® (USMLE) Step 1 exam as an important factor that residency program directors consider when deciding which applicants to interview and rank. Therefore, success on this exam, though only one aspect of applicant evaluation, is important in determining future career prospects for medical students. Unfortunately, mean test scores at the University of Illinois College of Medicine at Chicago (UIC) have historically been below the national average. This retrospective and quasi-experimental mixed-methods study describes the development, evaluation, and effects of a student-initiated USMLE Step 1 preparatory program at UIC. The program provided second year students with First Aid for the USMLE Step 1 at the beginning of the academic year, as well as a six month subscription to the USMLE World question bank midyear. In addition, optional peer review sessions covering basic sciences and organ systems were taught by high-performing upperclassmen. The goals of the program were to raise mean USMLE Step 1 exam scores and increase the percentage of students passing the exam on their first time. The program premiered during the 2012-13 academic year. Data from this cohort as well as four others (N = 830; 2010-2014 examinees) were gathered. Performances between preintervention (2010-12 examinees) and postintervention (2013-14 examinees) cohorts of students were compared. Focus groups and interviews with staff and students were conducted, recorded, and analyzed to investigate the impact that the program had on student interactions and perceptions of the learning environment. There was a significant difference in exam performance pre- versus postintervention, with average USMLE Step 1 scores improving by 8.82 points following the implementation of the student-initiated program, t(5.61) = 828, p < .001. The average first-attempt pass rate also increased significantly by 8%, χ 2 (1) = 23.13, p < .001

    To assess the experiences of a veteran initiated horticultural therapy garden during their 28-day inpatient Substance Abuse Residential Rehabilitation Treatment Program (SARRTP). Retrospective study. Veterans Affairs Medical Center (VAMC), Salem, Virginia, USA INTERVENTIONS: Group interviews with veterans from the last SARRTP classes and individual interviews with VAMC greenhouse staff in summer of 2016. Time spent in garden, frequency of garden visits, types of passive and active garden activities, words describing the veterans' emotional reactions to utilizing the garden. In 3 summer months of 2016, 50 percent of the 56 veterans interviewed visited and interacted with the gardens during their free time. Frequency of visits generally varied from 3 times weekly to 1-2 times a day. Amount of time in the garden varied from 10min to 2h. The veterans engaged in active and/or passive gardening activities during their garden visits. The veterans reported feeling "calm", "serene", and "refreshed" during garden visitation and after leaving the garden. Although data was secured only at the end of the 2016 growing season, interviews of the inpatient veterans revealed that they used their own initiative and resources to continue the horticulture therapy program for 2 successive growing years after the original pilot project ended in 2014. These non-interventionist, therapeutic garden projects suggest the role of autonomy and patient initiative in recovery programs for veterans attending VAMC treatment programs and they also suggest the value of horticulture therapy as a meaningful evidence- based therapeutic modality for veterans.

    2010-09-01

    Full Text Available During the last few years, users all over the world have become more and more familiar to the availability of broadband access. When users want broadband Internet service, they are generally restricted to a DSL (Digital Subscribers Line, or cable-modem-based connection. Proponents are advocating worldwide interoperability for microwave access (WiMAX, a technology based on an evolving standard for point-to multipoint wireless networking. Scheduling algorithms that support Quality of Service (QoS differentiation and guarantees for wireless data networks are crucial to the deployment of broadband wireless networks. The performance affecting parameters like fairness, bandwidth allocation, throughput, latency are studied and found out that none of the conventional algorithms perform effectively for both fairness and bandwidth allocation simultaneously. Hence it is absolutely essential for an efficient scheduling algorithm with a better trade off for these two parameters. So we are proposing a novel Scheduling Algorithm using Fuzzy logic and Artificial neural networks that addresses these aspects simultaneously. The initial results show that a fair amount of fairness is attained while keeping the priority intact. Results also show that maximum channel utilization is achieved with a negligible increment in processing time.

  5. Broadband RF Interferometric and Polarization Observations of Lightning Discharge Processes

    Shao, X. M.; Ho, C.; Caffrey, M.; Graham, P.; Haynes, H.; Dingus, B.

    2017-12-01

    Broadband radio frequency interferometry was first introduced in 1996 for detailed lightning mapping studies [Shao et al., 1996], and the technique has since been improved significantly and has been increasingly widely used in the lightning research community. Due to continuously advancing data acquisition and computer capabilities, it is now possible to capture and process continuous broadband interferometer data for individual lightning flashes. In addition to the interferometric mapping of the lightning sources, we now introduce a broadband polarization capability that measures simultaneously the full polarization state of the corresponding broadband RF sources. Polarization observation provides another level of understanding of the discharge processes. For instance, a coherent breakdown process (e.g., relativistic runaway electron avalanches) is expected to produce highly polarized RF emissions, while an incoherent process related to thermal electrons is expected to produce randomly polarized RF emissions. For polarized emissions, the direction of the polarization is expected to aligned with the direction of the local electric field, and therefore can be used to understand the electric field structure at the breakdown locations. In the early summer of 2017, this new lightning system was tested in Los Alamos with a number of nearby lightning storms, and the system will be deployed in the late summer to the High Altitude Water Cherenkov Gamma-Ray Observatory (HAWC) on the flanks of the Sierra Negra volcano in Mexico at an altitude of 4.1km. HAWC is designed to observe high energy celestial gamma rays and cosmic rays with hundreds of water tanks. The goal of the collaborative lightning and HAWC observations is to understand the physics behind the lightning-related gamma-ray flashes (TGFs) and the initiation of the lightning discharges. We will report the new results from both the test observations and the HAWC observations. *Shao, X., D. Holden, and C. Rhodes

  6. Global Biogeochemical Fluxes Program for the Ocean Observatories Initiative: A Proposal. (Invited)

    Science.gov (United States)

    Ulmer, K. M.; Taylor, C.

    2010-12-01

    The overarching emphasis of the Global Biogeochemical Flux Ocean Observatories Initiative is to assess the role of oceanic carbon, both living and non-, in the Earth climate system. Modulation of atmospheric CO2 and its influence on global climate is a function of the quantitative capacity of the oceans to sequester organic carbon into deep waters. Critical to our understanding of the role of the oceans in the global cycling of carbon are the quantitative dynamics in both time and space of the fixation of CO2 into organic matter by surface ocean primary production and removal of this carbon to deep waters via the “biological pump”. To take the next major step forward in advancing our understanding of the oceanic biological pump, a global observation program is required that: (i) greatly improves constraints on estimates of global marine primary production (PP), a critical factor in understanding the global CO2 cycle and for developing accurate estimates of export production (EP); (ii) explores the spatiotemporal links between PP, EP and the biogeochemical processes that attenuate particulate organic carbon (POC) flux; (iii) characterizes microbial community structure and dynamics both in the surface and deep ocean; (iv) develops a comprehensive picture of the chemical and biological processes that take place from the surface ocean to the sea floor; (v) provides unique time-series samples for detailed laboratory-based chemical and biological characterization and tracer studies that will enable connections to be made between the operation of the biological pump at present and in the geologic past. The primary goal is to provide high quality biological and biogeochemical observational data for the modeling and prediction efforts of the global CO2 cycle research community. Crucial to the realization of the GBF-OOI is the development of reliable, long-term, time-series ocean observation platforms capable of precise and controlled placement of sophisticated

    2014-01-01

    Complementary and alternative medicine (CAM) services, such as Reiki, continue to be offered to consumers in many hospitals and other health care organizations. There is growing interest among nurses, doctors, and other health care providers for the integration of CAM therapies into traditional settings. Health care organizations are responding to this need but may not know how to start CAM programs. Starting a Reiki program in a health care setting must be envisioned in a business model approach. This article introduces nurses and other health care providers to the basic concepts of business plan development and important steps to follow when starting a Reiki or CAM program.

  8. Green power programs in Canada : 2002 : Overview of Government green power policies, utility green power development programs, green power and certificate marketing initiatives, and their benefits

    Bramley, M.; Boustie, S.; Vadgama, J.; Wieler, C.; Pape-Salmon, A.; Holmes, R.

    2003-11-01

    Green power is generally defined as electricity produced from renewable sources, and whose production has low adverse impacts on the environment, human health and communities. Green power has near-zero greenhouse gas (GHG) emissions and includes sources such as wind, hydro, and solar power. Green power offers several environmental benefits, as well as the enhancement of energy security, regional development, economic diversification and the creation of skilled jobs. There are four categories of programs related to green power development in Canada: government green power policies, utility green power development programs, green power marketing initiatives, and green power certificate marketing initiatives. Most of the activities associated with these four categories in 2002 were discussed in this report. However, difficulties with quantification prevented the inclusion of some green power activities in the report, such as (1) the generation of green power not certified or identified by the generator as green power, (2) industry or residential self-generation, (3) net metering, and (4) small government programs. Each category was presented in detail. The information included in the report was based on surveys sent to each program proponent. Follow-up communications and other publicly available information was also included. New programs operating in 2003 or currently under development were listed. refs., 8 tabs

  10. Ionomer Dynamics: Insights from Broadband Dielectric Spectroscopy

    2015-03-01

    Ionomers (polymers containing ionic functionality) have been traditionally used as packaging materials and in molding applications, and are now of increasing interest as candidate single ion conductors for energy storage devices, in energy conversion, and for other electroactive materials applications. The focus of this presentation is on the insight that broadband dielectric (impedance) spectroscopy brings to our understanding of ion and polymer dynamics of this family of materials. As an example of our recent work on relatively conductive ionomers, the first portion of the presentation will focus on anion conducting polyphosphazene ionomers, in which polymer bound cations are quaternized with either short alkyl or short ether oxygen chains. The low Tg, amorphous nature, and cation-solvating backbone distinguish polyphosphazenes as promising materials for ion conduction, the iodide variants being of particular interest in solar cells. In the second part of this overview, the first findings on the molecular dynamics of linear precise polyethylene-based ionomers containing 1-methylimidazolium bromide pendants on exactly every 9th, 15th, or 21st carbon atom will be summarized. In order to develop a robust interpretation of the dynamics of these materials, it is imperative to develop a thorough understanding of microphase separation (e.g. ion aggregation), and each of the above studies is complimented by multiangle X-ray scattering experiments.

    To evaluate rates and predictors of retention into hepatocellular carcinoma (HCC) surveillance beyond initial screening among underserved cirrhosis patients. Although initial HCC screening among cirrhosis patients remains low, few studies have evaluated retention to HCC surveillance beyond initial screening. We retrospectively evaluated all consecutive adults with cirrhosis from 2014 to 2017 at a single underserved safety net hospital system to determine rates of HCC surveillance at 6 months and at 1 year beyond initial screening. Rates of HCC surveillance was stratified by sex, race/ethnicity, and etiology of liver disease. Multivariate Cox proportional hazards models evaluated predictors of retention into HCC surveillance. Among 235 cirrhosis patients [hepatitis C virus: 35.7%, hepatitis B virus (HBV): 15.7%, alcoholic cirrhosis: 36.2%, nonalcoholic steatohepatitis (NASH): 8.1%], mean age of cirrhosis diagnosis was 54.2±8.9 years. Overall, 74.8% received initial screening within 1 year of cirrhosis diagnosis. Among those who completed initial screening, 47.6% [95% confidence interval (CI), 41.4-54.2) received second surveillance within 1 year. On multivariate analyses, patients with NASH and HBV were significantly more likely to receive second HCC surveillance compared with hepatitis C virus, HBV (hazard ratio, 2.32; 95% CI, 1.18-4.56; P=0.014) and NASH (hazard ratio, 2.49; 95% CI, 1.22-5.11; P=0.012). No sex or race-specific/ethnicity-specific differences in HCC surveillance retention were observed. Although overall rates of initial HCC screening among cirrhosis patients is nearly 75%, retention into continued HCC surveillance is poor, with less than half of patients undergoing subsequent HCC surveillance. Cirrhosis patients with HBV and NASH were more likely to be retained into HCC surveillance.

    McDermott-Levy, Ruth; Fazzini, Carol

    2010-01-01

    Hospitals in the United States generate more than 6600 tons of trash a day and approximately 85% of the waste is nonhazardous solid waste such as food, cardboard, and plastic. Treatment and management of hospital waste can lead to environmental problems for the communities that receive the waste. One health system's shared governance model provided the foundation to develop a nurse-led hospital waste reduction program that focused on point-of-care waste management. Waste reduction program development required working with a variety of departments within and external to the health system. The interdisciplinary approach informed the development of the waste reduction program. This article identifies the key departments that were necessary to include when developing a hospital waste reduction program.

    Project TRIP (Transforming Relationships through Intergenerational Programs) was developed as a sustainable intergenerational community project involving child care participants and elders attending an elder care program or volunteering at the children's program. The project focused on staff development of evidence-based intergenerational practices. To enhance available intervention research, contact theory provided a theoretical framework to explore how staff members' and administrators' perceptions of the intervention influenced their ability to implement programming in social care settings. We used a directed content analysis approach to analyze small group and individual interviews with 32 participants from 6 program sites over 5 years. Participants highlighted inherent challenges and subsequent benefits of academic-community partnerships. Greater on-site presence, open communication, and relationship-building proved critical to improve community partnerships, project fidelity, and program sustainability. When interactions reflected contact theory tenets, collaborators reported positive attitudes toward and interactions with research partners. Contact theory provided a useful framework to understand the researcher-practitioner partnership. Researchers should plan for partnerships that: (a) are supported by authority figures, including staff and participants, (b) utilize a shared expertise approach where partners have equal group status, (c) involve close cooperation; (d) align research and program goals, and (e) foster positive communication through frequent contact using practitioners' preferred methods and including in-person contact. We recommend future intergenerational programming interventions build on a foundation of both theory and practice. © The Author(s) 2017.

    1983-01-01

    A broadband data communications network has been implemented at BNL for control of the Alternating Gradient Synchrotron (AGS) proton accelerator, using commercial CATV hardware, dual coaxial cables as the communications medium, and spanning 2.0 km. A 4 MHz bandwidth Digital Control Channel using CSMA-CA protocol is provided for digital data transmission, with 8 access nodes available over the length of the RELWAY. Each node consists of an rf modem and a microprocessor-based store-and-forward message handler which interfaces the RELWAY to a branch line implemented in GPIB. A gateway to the RELWAY control channel for the (preexisting) AGS Computerized Accelerator Operating System has been constructed using an LSI-11/23 microprocessor as a device in a GPIB branch line. A multilayer communications protocol has been defined for the Digital Control Channel, based on the ISO Open Systems Interconnect layered model, and a RELWAY Device Language defined as the required universal language for device control on this channel

  4. Interpreting Flux from Broadband Photometry

    Science.gov (United States)

    Brown, Peter J.; Breeveld, Alice; Roming, Peter W. A.; Siegel, Michael

    2016-10-01

    We discuss the transformation of observed photometry into flux for the creation of spectral energy distributions (SED) and the computation of bolometric luminosities. We do this in the context of supernova studies, particularly as observed with the Swift spacecraft, but the concepts and techniques should be applicable to many other types of sources and wavelength regimes. Traditional methods of converting observed magnitudes to flux densities are not very accurate when applied to UV photometry. Common methods for extinction and the integration of pseudo-bolometric fluxes can also lead to inaccurate results. The sources of inaccuracy, though, also apply to other wavelengths. Because of the complicated nature of translating broadband photometry into monochromatic flux densities, comparison between observed photometry and a spectroscopic model is best done by forward modeling the spectrum into the count rates or magnitudes of the observations. We recommend that integrated flux measurements be made using a spectrum or SED which is consistent with the multi-band photometry rather than converting individual photometric measurements to flux densities, linearly interpolating between the points, and integrating. We also highlight some specific areas where the UV flux can be mischaracterized.

    Jamin, Olivier

    2014-01-01

    This book discusses the trade-offs involved in designing direct RF digitization receivers for the radio frequency and digital signal processing domains.  A system-level framework is developed, quantifying the relevant impairments of the signal processing chain, through a comprehensive system-level analysis.  Special focus is given to noise analysis (thermal noise, quantization noise, saturation noise, signal-dependent noise), broadband non-linear distortion analysis, including the impact of the sampling strategy (low-pass, band-pass), analysis of time-interleaved ADC channel mismatches, sampling clock purity and digital channel selection. The system-level framework described is applied to the design of a cable multi-channel RF direct digitization receiver. An optimum RF signal conditioning, and some algorithms (automatic gain control loop, RF front-end amplitude equalization control loop) are used to relax the requirements of a 2.7GHz 11-bit ADC. A two-chip implementation is presented, using BiCMOS and 65nm...

  6. Broadband electromagnetic environments simulator (EMES)

    International Nuclear Information System (INIS)

    Pollard, N.

    1977-01-01

    A new test facility has been developed by Sandia Laboratories for determining the effects of electromagnetic environments on systems and components. The facility is capable of producing uniform, vertically polarized, continuous wave (CW) and pulsed fields over the frequency range of dc to 10 GHz. This broadband capability addresses the electromagnetic radiation (EMR) threat and is ideally suited to computer controlled sweeping and data acquisition. EMES is also capable of producing uniform transient fields having the wave shape and magnitude characteristic of a nuclear electromagnetic pulse (EMP) and near lightning. The design consists of a truncated, triplate, rectangular coaxial transmission line. The spacing between the flat center conductor and the ground planes is 4 meters. The line is terminated in its characteristic impedance of 50 ohms. At frequencies below the first resonance of the facility it behaves as a typical coaxial system. Above resonance, a wall of electromagnetic absorbing material provides a nonreflecting termination. Thus, EMES essentially combines the elements of a transmission line and an anechoic chamber. It will not radiate electromagnetic energy into the surrounding area because it is a shielded transmission line

    2005-01-01

    Most research to assess amphibian declines has focused on local-scale projects on one or a few species. The Amphibian Research and Monitoring Initiative (ARMI) is a national program in the United States mandated by congressional directive and implemented by the U.S. Department of the Interior (specifically the U.S. Geological Survey, USGS). Program goals are to monitor changes in populations of amphibians across U.S. Department of the Interior lands and to address research questions related to amphibian declines using a hierarchical framework of base-, mid- and apex-level monitoring sites. ARMI is currently monitoring 83 amphibian species (29% of species in the U.S.) at mid- and apex-level areas. We chart the progress of this 5-year-old program and provide an example of mid-level monitoring from 1 of the 7 ARMI regions.

  14. Digital Divides and the 'First Mile': Framing First Nations Broadband Development in Canada

    Directory of Open Access Journals (Sweden)

    Rob McMahon

    2011-05-01

    Full Text Available Across Canada, rural and remote First Nations face a significant 'digital divide'. As self-determining autonomous nations in Canada, these communities are building broadband systems to deliver public services to their members and residents. To address this challenge, First Nations are working towards a variety of innovative, locally driven broadband development initiatives. This paper contributes a theoretical discussion that frames our understanding of these initiatives by drawing on the paradigm of the 'First Mile' (Paisley & Richardson, 1998. We argue that broadband development policy in Canada must be re-framed to address the specific needs of First Nations. The First Mile position foregrounds community-based involvement, control, and ownership: a consideration we suggest has particular resonance for First Nations. This is because it holds potential to move beyond the historical context of paternalistic, colonial-derived development policies, in the context of broadband systems development. We argue First Nations broadband projects offer on-the-ground examples of a First Mile approach, and call for more research in this area.

    The freshman academic year is one of the most difficult years that a medical student experiences in his/her academic life at a medical school. Freshmen are frequently faced with several challenges, such as adaptation to a new academic environment and its associated different methods of teaching, learning, skills, and assessment. The aim of this study was to describe a 4-wk innovative summer premedical program developed by senior medical students at the College of Medicine, Alfaisal University, in an attempt to improve/smooth the experience(s) of prospective freshmen. This report describes the objectives/strategies/methodologies used to tackle the top three identified freshman challenges, namely, 1) advancement of the academic/scholastic/educational background, 2) the development of college-required skills to succeed and excel in the freshman year, and 3) adaption to the college environment. At the end of the program, a survey was conducted to evaluate the effectiveness of the summer premedical program. Seventy-two students attended this program over the past three summers from 2010 to 2012, and twenty-nine students answered the survey with a response rate of 74.1%. Overall, >90% of the survey respondents reported an improvement in their understanding of basic medical science, integration, presentation skills, medical terminology, and junior-senior relationships. Furthermore, the survey highlighted the need for more focus on skills such as time management, participation in large-group discussions, and use of electronic resources, as >50% of respondents reported no improvement in these areas. In conclusion, this is the first report, to our knowledge, that describes a program developed by senior medical students to improve the experience of freshmen.

    The slowing pace of performance improvement in the commonly available processors is a cause of concern amongst many computational scientists. This combined with the ever increasing need for computational power has caused us to turn to alternative architectures in search of performance gains. Two main candidates were the Compute Unified Device Architecture (CUDA) and the Cell Broadband Engine (CELL BE) architecture. This paper focuses on the latter, outlining the architecture and basic programming paradigms, and also contains performance comparison of algorithms currently developed by our team.

    Although private forest use in Brazil has been regulated at least since the Forest Code of 1965, cumulative deforestation in the Brazilian Amazon reached 653,000 km2 by 2003 (INPE 2004). Much of this deforestation is illegal. In 1999, the State Foundation of the Environment (FEMA) in Mato Grosso introduced an innovative licensing and enforcement system to increase compliance with land use regulations. If successful, the program would deter deforestation that contravenes those regulations, inc...

  7. Can faith-based correctional programs work? An outcome evaluation of the innerchange freedom initiative in Minnesota.

    Science.gov (United States)

    Duwe, Grant; King, Michelle

    2013-07-01

    This study evaluated the effectiveness of the InnerChange Freedom Initiative (InnerChange), a faith-based prisoner reentry program, by examining recidivism outcomes among 732 offenders released from Minnesota prisons between 2003 and 2009. Results from the Cox regression analyses revealed that participating in InnerChange significantly reduced reoffending (rearrest, reconviction, and new offense reincarceration), although it did not have a significant impact on reincarceration for a technical violation revocation. The findings further suggest that the beneficial recidivism outcomes for InnerChange participants may have been due, in part, to the continuum of mentoring support some offenders received in the institution and the community. The results imply that faith-based correctional programs can reduce recidivism, but only if they apply evidence-based practices that focus on providing a behavioral intervention within a therapeutic community, addressing the criminogenic needs of participants and delivering a continuum of care from the institution to the community. Given that InnerChange relies heavily on volunteers and program costs are privately funded, the program exacts no additional costs to the State of Minnesota. Yet, because InnerChange lowers recidivism, which includes reduced reincarceration and victimization costs, the program may be especially advantageous from a cost-benefit perspective.

    Introduction: NASA has played an influential role in bringing the enthusiasm of space science to schools across the United States since the 1980s. The evolution of this public outreach has led to a variety of NASA funded education programs designed to promote student interest in science, technology, engineering, math, and geography (STEM-G) careers. Purpose: This paper investigates the educational outreach initiatives, structure, and impact of two of NASA's largest educational programs: the NASA Explorer School (NES) and NASA Spaceward Bound programs. Results: Since its induction in 2003 the NES program has networked and provided resources to over 300 schools across the United States. Future directions include further development of mentor schools for each new NES school selected, while also developing a longitudinal student tracking system for NES students to monitor their future involvement in STEM-G careers. The Spaceward Bound program, now in its third year of teacher outreach, is looking to further expand its teacher network and scientific collaboration efforts, while building on its teacher mentorship framework. ?? 2009 Elsevier Ltd.

    Satisfaction with information on medication is linked to adherence, but patients are often dissatisfied with information about medication. Information about treatment with fingolimod is important for MS patients since an active role in managing treatment is required from them. To facilitate optimal treatment initiation, a nurse-led patient education program on fingolimod was implemented in a Swiss MS center. To evaluate the impact of the evidence-based comprehensive patient education program on knowledge, self-efficacy and patient satisfaction. Knowledge gain, subjective perception of being informed about the new treatment, self-efficacy in handling it and satisfaction with the program were evaluated in a pretest-posttest design. Patient reported outcomes were collected before and after an educational session on the first-dose day at the MS Center in a consecutive sample of 98 people with MS. Data was analyzed descriptively, score comparisons were done by Wilcoxon tests, and associations were estimated with Spearman's correlation coefficient. Knowledge increased significantly from pre- to posttest. Similarly, perception of being informed and self-efficacy increased significantly. Satisfaction with the program was high. Pretest-differences in knowledge concerning gender and marital status were balanced after the educational session. Results did not differ between patients with fingolimod as first treatment and those switching from other MS treatments. At posttest perception of being informed and self-efficacy were significantly related to satisfaction. An evidence-based comprehensive treatment education program is suitable to satisfy MS patients' information needs at treatment initiation. It enhances short-term treatment knowledge and self-efficacy in handling a new treatment in daily life. MS Nurses can thus contribute to effective treatment education and potentially to medication safety and adherence. Copyright © 2015 Elsevier B.V. All rights reserved.

    Education and training are key elements of disaster management. Despite national and international educational programs in disaster management, there is no standardized curriculum available to guide the European Union (EU) member states. European- based Disaster Training Curriculum (DITAC), a multiple university-based project financially supported by the EU, is charged with developing a holistic and highly-structured curriculum and courses for responders and crisis managers at a strategic and tactical level. The purpose of this study is to qualitatively assess the prevailing preferences and characteristics of disaster management educational and training initiatives (ETIs) at a postgraduate level that currently exist in the EU countries. An Internet-based qualitative search was conducted in 2012 to identify and analyze the current training programs in disaster management. The course characteristics were evaluated for curriculum, teaching methods, modality of delivery, target groups, and funding. The literature search identified 140 ETIs, the majority (78%) located in United Kingdom, France, and Germany. Master level degrees were the primary certificates granted to graduates. Face-to-face education was the most common teaching method (84%). Approximately 80% of the training initiatives offered multi- and cross-disciplinary disaster management content. A competency-based approach to curriculum content was present in 61% of the programs. Emergency responders at the tactical level were the main target group. Almost all programs were self-funded. Although ETIs currently exist, they are not broadly available in all 27 EU countries. Also, the curricula do not cover all key elements of disaster management in a standardized and competency-based structure. This study has identified the need to develop a standardized competency-based educational and training program for all European countries that will ensure the practice and policies that meet both the standards of care and

    Transthoracic echocardiography (TTE) is a non-invasive diagnostic modality for children with suspected heart disease. The American College of Cardiology published Appropriate Use Criteria (AUC) for an initial outpatient pediatric TTE in 2014 to promote effective care and improve resource utilization. The objective was to determine the appropriateness of TTE per the published AUC in a single academic pediatric cardiology clinic as a baseline performance quality measure. The echocardiography database was used to identify initial outpatient TTE in children during January-March 2014. TTE indications (appropriate [A], may be appropriate [M], or rarely appropriate [R]) and findings (normal, incidental, or abnormal) were recorded. The effect of AUC and age groups on yield of abnormal TTE findings was analyzed. Of the 2166 screened studies, our study cohort consisted of 247 TTEs. Indications rated A, M, and R were found in 129, 27, and 90, respectively, and 1 was unclassifiable. Majority of TTE (n = 183) were normal, although incidental findings were noted in 32 and abnormal findings in 32 cases. Abnormal findings were noted in 26/129 of A, 2/27 of M, and 4/90 of R. Indications rated A were significantly associated with yield of abnormal TTE findings, adjusted by age group. Infants and adolescents were more likely to have abnormal TTE findings compared to young children. Recently published AUC were validated for initial TTE in the outpatient pediatric cardiology clinic. Appropriateness rated by AUC was highly associated with yield of abnormal TTE findings and worked best in infants and adolescent.

    The aims of the study were to evaluate the long-term effects of a home-based smoking prevention program 'Smoke-free Kids' during preadolescence on smoking initiation during adolescence and to test the potential moderating role of parental smoking, socioeconomic status, and asthma. In 2008, 1478 9-11year old children and their mothers were recruited from 418 elementary schools in the Netherlands. An independent statistician randomly allocated schools to one of the two conditions using a 1:1 ratio (single blind): 728 children in the intervention and 750 in the control condition. The intervention condition received five activity modules, including a communication sheet for mothers, by mail at four-week intervals and one booster module one year after baseline. The control condition received a fact-based intervention only. Intention-to-treat analysis was performed on 1398 non-smoking children at baseline. In the intervention 10.8% of the children started smoking compared to 12% in the control condition. This difference was non-significant (odds ratio=0.90, 95% confidence interval=0.63-1.27). No moderating effects were found. No effects on smoking initiation after 36months were found. Perhaps, the program was implemented with children that were too young. Programs closer to the age of smoking onset should be tested. Copyright © 2013 Elsevier Inc. All rights reserved.

    Green power is defined as electricity produced from renewable sources, and whose production has low adverse impacts on the environment, human health and communities. Green power has near-zero greenhouse gas (GHG) emissions and includes sources such as wind, hydro, and solar power. It offers several environmental benefits, as well as the enhancement of energy security, regional development, economic diversification and the creation of skilled jobs. There are four categories of programs related to green power development in Canada: government green power policies, utility green power development programs, green power marketing initiatives, and green power certificate marketing initiatives. Most of the activities in Canada associated with these four categories in 2003 were discussed in this report. However, difficulties with quantification prevented the inclusion of some green power activities such as (1) the generation of green power not certified or identified by the generator as green power, (2) industry or residential self-generation, (3) net metering, and (4) small government programs. Green power generation facilities in 2003 totaled 775 MW of capacity compared to 539 MW in 2002. Hydro capacity represented 41 per cent, followed by wind capacity at 40 per cent and wood waste at 17 per cent. Most of the green power generation facilities in 2003 were located in Alberta, followed by British Columbia, Ontario and Quebec. 230 refs., 8 tabs., 1 fig

    Full Text Available Summary: Therapies targeting epidermal growth factor receptor (EGFR have variable and unpredictable responses in breast cancer. Screening triple-negative breast cancer (TNBC patient-derived xenografts (PDXs, we identify a subset responsive to EGFR inhibition by gefitinib, which displays heterogeneous expression of wild-type EGFR. Deep single-cell RNA sequencing of 3,500 cells from an exceptional responder identified subpopulations displaying distinct biological features, where elevated EGFR expression was significantly enriched in a mesenchymal/stem-like cellular cluster. Sorted EGFRhi subpopulations exhibited enhanced stem-like features, including ALDH activity, sphere-forming efficiency, and tumorigenic and metastatic potential. EGFRhi cells gave rise to EGFRhi and EGFRlo cells in primary and metastatic tumors, demonstrating an EGFR-dependent expansion and hierarchical state transition. Similar tumorigenic EGFRhi subpopulations were identified in independent PDXs, where heterogeneous EGFR expression correlated with gefitinib sensitivity. This provides new understanding for an EGFR-dependent hierarchy in TNBC and for patient stratification for therapeutic intervention. : Savage et al. demonstrate that sensitivity to EGFR inhibitor, gefitinib, in triple-negative breast cancer is paradoxically associated with EGFR heterogeneity. Using single-cell RNA sequencing in conjunction with functional assays, they identify TNBC tumors in which EGFR expression identifies cells with tumor-initiating capacity whose proliferative expansion is sensitive to EGFR inhibition.

    In 1991, the Superconducting Super Collider Laboratory (SSCL) instituted a program to qualify specific superconductor manufacturers for production of cable acceptable for use in both Collider Dipole (CDM) and Quadrupole (CQM) magnets. The SSCL Vendor Qualification Program (VQP) was designed with two Phases. Phase 1 was divided into two additional phases, 1A and 1B, which ran concurrently. In Phase 1B, each vendor was directed to manufacture roughly 3000 kg of cable using a ''baseline'' process. The baseline process was agreed to by both the SSCL and the vendor at the beginning of the VQP. In this phase, process control was closely monitored with the use of statistical methods and each vendor was graded based on these results. Phase 1A, known as the R ampersand D phase, was developed to allow each vendor an opportunity to optimize and improve on their baseline process in terms of both cost and manufacturability. In this phase, multifilament billets were designed to explore several key variables such as alternate alloy sources, process modifications and improved billet designs. At the end of Phase 1, the results from both 1A and 1B were evaluated at a review between the SSCL and each vendor, and a final Phase 2 process was generated and fixed using the best results. In Phase 2, each vendor is required to manufacture roughly 6000 kg of superconducting cable under a firm fixed price contract which can then be used to create an accurate price estimate for competitive bidding on the full rate production CDM and CQM contracts. At the end of Phase 2, each vendor must meet the minimum requirements outlined in the contract to become a qualified superconducting cable supplier. For one requirement, critical process variables identified by the SSCL Conductor Department at the beginning of the VQP will be evaluated to determine the quality and uniformity of the material produced during Phase 2 of the program

    Introduction Annually, especially in poor resourced countries, significant amount of money is spent to treat chronic diseases. The money instead could be saved by spending on health promotion programs for preventing chronic diseases. Aim To conduct cost-effectiveness analysis of various intervention modules in the “Smoking Cessation” program conducted in Universiti Sains Malaysia (USM). Materials and Methods This was an observational study design. Cost-effectiveness analysis was used to assess the costs and outcomes of the intervention. Data were collected retrospectively from medical records of all clients (n= 129) and then all the participants were followed-up for at least 6 months from the date of participation. Data were analysed descriptively using frequency (%) and mean (sd). Kolmogorov-Smirnov test was carried out to test for normality. Chi-square and Kruskal-Wallis tests were used at alpha level of 0.05. All analyses were done using SPSS version 19. Results The findings of the study showed that the majority of participants were Malays (n= 108; 83.7%), males (n= 128; 99.2%), USM’s staff (n= 71; 55.0%) and within an age group of 23 years or less (n= 38; 29.5%). Among those who successfully quit were male (n= 30; 100%), Malays (n= 29; 96.7%), staff (n= 19; 63.3%), moreover, their age ranged from 35 to 56-year-old (n= 15; 50.0%). Further analysis of data showed that there were significant associations between success rate and modules of intervention, occupation, motivation factors, and frequency of counselling. Total cost of the Smoking Cessation Program was MYR 38,634.66 (during a period of 34.5 months), with a success rate equal to 29.1%. The most cost-effective module of intervention was counselling alone (CE ratio equal to MYR360.00 per 1% of success rate). The study found counselling with patch was ineffective during the study period. Conclusion Counselling alone module was the most cost-effective in Smoking Cessation program conducted in USM

  19. Identifying Broadband Rotational Spectra with Neural Networks

    Zaleski, Daniel P.; Prozument, Kirill

    2017-06-01

    A typical broadband rotational spectrum may contain several thousand observable transitions, spanning many species. Identifying the individual spectra, particularly when the dynamic range reaches 1,000:1 or even 10,000:1, can be challenging. One approach is to apply automated fitting routines. In this approach, combinations of 3 transitions can be created to form a "triple", which allows fitting of the A, B, and C rotational constants in a Watson-type Hamiltonian. On a standard desktop computer, with a target molecule of interest, a typical AUTOFIT routine takes 2-12 hours depending on the spectral density. A new approach is to utilize machine learning to train a computer to recognize the patterns (frequency spacing and relative intensities) inherit in rotational spectra and to identify the individual spectra in a raw broadband rotational spectrum. Here, recurrent neural networks have been trained to identify different types of rotational spectra and classify them accordingly. Furthermore, early results in applying convolutional neural networks for spectral object recognition in broadband rotational spectra appear promising. Perez et al.

    2013-06-01

    Studies of one-to-one programs consistently report lower use of laptops in mathematics classrooms compared to other subjects but do not elaborate reasons for these observations. This mixed-method study investigated the experiences and beliefs of 28 mathematics teachers at five secondary schools during the second year of the New South Wales Digital Education Revolution laptop program. While some mathematics teachers planned for students to use their laptops up to once a week, most reported less frequent use in the classroom. Teachers were grouped into categories "Non Adopters," "Cautious Adopters," and "Early Adopters" according to reported classroom use of laptops, then analysed for differences in confidence, knowledge, and beliefs relating to technology for teaching and learning mathematics. A prevalent belief limiting laptop use is that students authentically learn mathematics only using pen and paper. Cautious Adopters and Non Adopters expressed beliefs that laptops exacerbate classroom management problems, especially for lower-achieving students. In the context of ability-streamed classes these beliefs effectively ruled out use of laptops for entire classrooms.

    Kellams, Joni R; Maye, John P

    Nurse practitioners (NPs) now have prescriptive authority for controlled substances in all 50 states in the United States. Florida, the last state to grant NPs DEA licensure, has been wrought with prescription diversion practices for a number of years as pill mills, doctor shopping, and overprescribing proliferated. Prescription Drug Monitoring Programs (PDMPs) help curb drug diversion activity and play a key role in reducing the abuse of controlled substances. The primary objective of this education improvement initiative was to increase knowledge of actively licensed NPs in the state of Florida regarding the state's PDMP. The main themes included the drug abuse problem, description and progression of the PDMP, and how to use the Florida PDMP. Upon approval from the institutional review board, this education improvement initiative gauged NP knowledge of the PDMP and main themes before and after an educational PowerPoint intervention. A pretest/posttest questionnaire was administered for assessment of all knowledge questions. One hundred forty-five NPs with active advanced registered NP licenses in Florida completed both the pretest and posttest questionnaires. Descriptive statistics and paired t tests were used for statistical significance testing. Knowledge of the PDMP and the main themes of the education improvement initiative significantly increased (p < .001) from pretest to posttest results. This education improvement initiative had positive effects for NPs on the knowledge of the Florida PDMP and the main themes. This indicated that Florida NPs are able to acquire greater comprehension of the PDMP by an education intervention.

    Broadband seismometers deployed at Aso volcano in Japan have detected a hydrothermal reservoir 1 to 1.5 kilometers beneath the crater that is continually resonating with periods as long as 15 seconds. When phreatic eruptions are observed, broadband seismograms elucidate a dynamic interplay between the reservoir and discharging flow along the conduit: gradual pressurization and long-period (~20 seconds) pulsations of the reservoir during the 100 to 200 seconds before the initiation of the discharge, followed by gradual deflation of the reservoir concurrent with the discharging flow. The hydrothermal reservoir, where water and heat from the deeper magma chamber probably interact, appears to help control the surface activity at Aso volcano.

    We present the analytical design and experimental realization of a scheme based on multi-arm coiling slits to generate the stable acoustic vortices in a broadband. The proposed structure is able to spiral the acoustic wave spatially and generate the twisted acoustic vortices with invariant topological charge for a long propagation distance. Compared with conventional methods which require the electronic control of a bulky loudspeaker, this scheme provides an effective and compact solution to generate acoustic vortices with controllable topological charge in the broadband, which offers more initiatives in the demanding applications.

    Reduction of greenhouse gas emissions that have built up over a century is a long-term challenge which requires long-term, sustainable solutions. The solutions include the increasing need for Canadians to use less carbon intensive fuels, such as natural gas. There are no economically and socially acceptable quick fixes that will produce dramatic results on a large scale. The endorsement of the Voluntary Climate Change Challenge and Registry Program (VCR) by the Canadian Gas Association (CGA), and subsequent approval of the Memorandum of Understanding, are indicative of commitments by the Association and its member companies to environmentally responsible actions and measures to ensure efficient energy usage. While CGA and members continue to reduce emissions, it must be recognized that significant progress will take time. Given the benefits of a long-term sustainable approach, the Voluntary Challenge represents the most logical way to proceed to reduce greenhouse gas emissions from Canadian sources without causing severe economic dislocation.

    Pharmacists and pharmacy technicians have an opportunity to impact the quality of the medication histories and improve patient safety by ensuring accurate medication lists are obtained and complete reconciliation has occurred with the admission medication orders by owning the admission medication reconciliation process. To compare the quality of a pharmacy-based medication reconciliation program on admission utilizing pharmacists and technicians to the usual multidisciplinary process. This was a retrospective chart review process improvement study at a 186-bed tertiary care inpatient facility. Primary outcomes included both the accuracy of pre-admission medications listed and the reconciliation of those medications with admission inpatient orders. Technicians obtained patient medication histories. Pharmacists checked the technician-obtained medication histories and ensured reconciliation of those medications with admission orders. Medication accuracy increased from 45.8% to 95% per patient (P process improvement data collection.

    Background Mental Health First Aid (MHFA) training was developed in Australia to teach members of the public how to give initial help to someone developing a mental health problem or in a mental health crisis situation. However, this type of training requires adaptation for specific cultural groups in the community. This paper describes the adaptation of the program to create an Australian Aboriginal and Torres Strait Islander Mental Health First Aid (AMHFA) course and presents an initial evaluation of its uptake and acceptability. Methods To evaluate the program, two types of data were collected: (1) quantitative data on uptake of the course (number of Instructors trained and courses subsequently run by these Instructors); (2) qualitative data on strengths, weaknesses and recommendations for the future derived from interviews with program staff and focus groups with Instructors and community participants. Results 199 Aboriginal people were trained as Instructors in a five day Instructor Training Course. With sufficient time following training, the majority of these Instructors subsequently ran 14-hour AMHFA courses for Aboriginal people in their community. Instructors were more likely to run courses if they had prior teaching experience and if there was post-course contact with one of the Trainers of Instructors. Analysis of qualitative data indicated that the Instructor Training Course and the AMHFA course are culturally appropriate, empowering for Aboriginal people, and provided information that was seen as highly relevant and important in assisting Aboriginal people with a mental illness. There were a number of recommendations for improvements. Conclusion The AMHFA program is culturally appropriate and acceptable to Aboriginal people. Further work is needed to refine the course and to evaluate its impact on help provided to Aboriginal people with mental health problems. PMID:19490648

    Physical activity can prevent or delay the onset of physical functional limitations in older adults. There are limited data that evidence-based physical activity interventions can be successfully translated into community programs and result in similar benefits for physical functioning. The purpose of this study is to measure the effects of the Active Living Every Day program on physical functioning and physical functional limitations in a diverse sample of older adults. As a part of the Active for Life initiative, the Council on Aging of Southwestern Ohio implemented Active Living Every Day (ALED), a group-based lifestyle behavior change program designed to increase physical activity. Performance-based physical functioning tests (30-s Chair Stand Test, eight Foot Up-and-Go Test, Chair Sit-and-Reach Test, 30-Foot Walk Test) were administered to participants at baseline and posttest. Baseline to post-program changes in physical functioning and impairment status were examined with repeated measures analysis of covariance. Interactions tested whether change over time differed according to race/ethnicity, body mass index (BMI), and baseline impairment status. Participants significantly increased their performance in all four physical functioning tests. The percentage of participants classified as "impaired" according to normative data significantly decreased over time. Physical functioning improved regardless of BMI, race/ethnicity, or baseline impairment status. ALED is an example of an evidenced-based physical activity program that can be successfully translated into community programs and result in significant and clinically meaningful improvements in performance-based measures of physical functioning.

    A formal research program enhances resident training experience, productivity and hones critical appraisal skills. This initiative sought to investigate if an academic orthopaedic surgery department could implement a clinical research program, with the goal of increasing resident scholarly activity, a requirement of the Resident Review Committee, and achieve a parallel aim of enhancing the research focus of faculty. A multifaceted intervention including a needs assessment, appropriation of dedicated research staffing, development of tracking tools and policies, and a formalized research curriculum, followed by additional research time for residents was planned and implemented. The impact of all of these efforts is measured with specific outcomes, pre and post implementation. The North Shore-LIJ Orthopaedic Surgery Department is a high volume clinical and education program with 17 fulltime core faculty and 18 residents at 2 tertiary hospitals. Residents were the focus of the intervention. The participation of faculty as principal investigators and sponsors was a key component to ensure success. The following outcomes were observed post intervention: increases in institutionally-required research training for faculty/residents, number of IRB protocols submitted, abstracts submitted to national meetings, percentage of time faculty report they spend on research activities, additional hours allocated to the new Department sponsored research curriculum and an additional research rotation for trainees. The official inception of a formalized program (2012) with a structured research process, invigorated faculty and trainees to formulate clinical research inquiries, generate hypotheses, create protocols and design and implement protocols. Structured tools, an experienced clinical research "champion" and commitment from departmental leadership were demonstrated as effective in transforming the focus of a clinical department into one with a nascent clinical research program

    Background U.S. state AIDS Drug Assistance Programs (ADAPs) are federally funded to provide antiretroviral therapy (ART) as the payer of last resort to eligible persons with HIV infection. States differ regarding their financial contributions to and ways of implementing these programs, and it remains unclear how this interstate variability affects HIV treatment outcomes. Methods We analyzed data from HIV-infected individuals who were clinically-eligible for ART between 2001 and 2009 (i.e., a first reported CD4+ <350 cells/uL or AIDS-defining illness) from 14 U.S. cohorts of the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD). Using propensity score matching and Cox regression, we assessed ART initiation (within 6 months following eligibility) and virologic suppression (within 1 year) based on differences in two state ADAP features: the amount of state funding in annual ADAP budgets and the implementation of waiting lists. We performed an a priori subgroup analysis in persons with a history of injection drug use (IDU). Results Among 8,874 persons, 56% initiated ART within six months following eligibility. Persons living in states with no additional state contribution to the ADAP budget initiated ART on a less timely basis (hazard ratio [HR] 0.73, 95% CI 0.60–0.88). Living in a state with an ADAP waiting list was not associated with less timely initiation (HR 1.12, 95% CI 0.87–1.45). Neither additional state contributions nor waiting lists were significantly associated with virologic suppression. Persons with an IDU history initiated ART on a less timely basis (HR 0.67, 95% CI 0.47–0.95). Conclusions We found that living in states that did not contribute additionally to the ADAP budget was associated with delayed ART initiation when treatment was clinically indicated. Given the changing healthcare environment, continued assessment of the role of ADAPs and their features that facilitate prompt treatment is needed. PMID:24260137

  11. Group velocity effects in broadband frequency conversion on OMEGA. 1998 summer research program for high school juniors at the University of Rochester's Laboratory for Laser Energetic. Student research reports

    The powerful lasers needed for ICF can only produce light in the infrared wavelengths. However, the one micron wavelength produced by the neodymium glass that powers OMEGA and other lasers used for fusion research does not efficiently compress the fuel pellet. This happens because the infrared light is not well absorbed by the target, and because of the creation of suprathermal electrons. These suprathermal electrons preheat the fuel, adding extra resistance to compression. To eliminate these problems associated with longer wavelengths of light, the process of frequency converting the laser beam was invented. This process efficiently converts the initial beam to a beam which has three times the frequency and one third the wavelength. The third-harmonic beam, in the UV range, has a better absorption rate. The PV-WAVE computer program that the author has written has shown that increasing the frequency of SSD (Smoothing by Spectral Dispersion) on OMEGA to approximately 10 GHz as planned will not hurt the third harmonic generation conversion efficiency significantly. The increased bandwidth and increased frequency of SSD will make the laser beams that strike the target on OMEGA much smoother and more uniform than ever before. Therefore it is both safe and advisable to add a second tripler crystal to the OMEGA system and decrease the SSD time cycle to around 100 picoseconds. Since the conversion efficiency remains high up to approximately 30 GHz, more experiments on OMEGA may be carried out with even higher modulation frequencies. These modifications to the existing OMEGA laser should make target irradiation more uniform, leading to more uniform compression and hopefully, a higher energy yield

  12. Initial Findings from a Novel School-Based Program, EMPATHY, Which May Help Reduce Depression and Suicidality in Youth.

    Full Text Available We describe initial pilot findings from a novel school-based approach to reduce youth depression and suicidality, the Empowering a Multimodal Pathway Towards Healthy Youth (EMPATHY program. Here we present the findings from the pilot cohort of 3,244 youth aged 11-18 (Grades 6-12. They were screened for depression, suicidality, anxiety, use of drugs, alcohol, or tobacco (DAT, quality-of-life, and self-esteem. Additionally, all students in Grades 7 and 8 (mean ages 12.3 and 13.3 respectively also received an 8-session cognitive-behavioural therapy (CBT based program designed to increase resiliency to depression. Following screening there were rapid interventions for the 125 students (3.9% who were identified as being actively suicidal, as well as for another 378 students (11.7% who were felt to be at higher-risk of self-harm based on a combination of scores from all the scales. The intervention consisted of an interview with the student and their family followed by offering a guided internet-based CBT program. Results from the 2,790 students who completed scales at both baseline and 12-week follow-up showed significant decreases in depression and suicidality. Importantly, there was a marked decrease in the number of students who were actively suicidal (from n=125 at baseline to n=30 at 12-weeks. Of the 503 students offered the CBT program 163 (32% took part, and this group had significantly lower depression scores compared to those who didn't take part. There were no improvements in self-esteem, quality-of-life, or the number of students using DAT. Only 60 students (2% of total screened required external referral during the 24-weeks following study initiation. These results suggest that a multimodal school-based program may provide an effective and pragmatic approach to help reduce youth depression and suicidality. Further research is required to determine longer-term efficacy, reproducibility, and key program elements.ClinicalTrials.gov NCT

    Costs for active double-star fiber networks for local exchange service are compared with the costs of copper twisted-pair single-star networks and copper coaxial-line tree networks with switching at the customer's premises. For both existing and new neighborhoods, it appears that delivery of broadband services through tree networks (possibly using fiber) and delivery of narrow band services through copper twisted-pair star networks will be the minimum cost approach for low market penetrations of the broadband service market. For near 100 percent market penetrations there is relatively little difference in the costs of the two approaches.

  14. Conclusions from the Oak Ridge EPR studies and initiation of the TNS program. A brief summary

    International Nuclear Information System (INIS)

    Roberts, M.

    1977-03-01

    This ORNL study has resulted in an evaluated reference design that does satisfy the technical objectives set out for a Tokamak Experimental Power Reactor (EPR). Because of this design's large size, high cost, and poor extrapolation to a demonstration reactor, the basic physics and range of technical objectives have been reconsidered. This has led to an intermediate step and new design, The Next Step (TNS) after TFTR, having a higher benefit/cost than EPR. The TNS program, now in the early design phases, is focused on a device with smaller size and considerably higher power output than the EPR design. This device's improved performance is made possible by a projection of operation at higher plasma density than that assumed for EPR. This more optimistic plasma performance projection is based on a reexamination of basic physics assumptions and of current plasma physics experiments; a focused experimental and theoretical effort will be required in the near future to validate this projection. With this improved performance, the TNS designs can be extrapolated to an economically viable fusion reactor

    The purpose of this project was to enhance the knowledge of the bedside nurse in diabetes management. A forum for ongoing support and exploration of clinical problems, along with the distribution of educational tools were the components of this program. Diabetes accounts for 30% of patients admitted to the hospital. It has become more challenging to manage as the treatment choices have increased. There are a number of researchers who have identified nurse and physician knowledge of diabetes management principles as suboptimal. DESCRIPTION OF THE INNOVATION: Staff nurses are educated for a role as a Diabetes Management Mentor and are expected to educate/dialogue with peers monthly, model advocacy and diabetes patient education skills, facilitate referrals for diabetes education, and direct staff to resources for diabetes management. Diabetes Management Mentors feel more confident in their knowledge of diabetes and their ability to resolve clinical issues as they arise. The Diabetes Management Mentor role is another avenue for nurses to refine their clinical knowledge base and acquire skills to share with colleagues while remaining at the bedside. The clinical nurse specialist is expertly prepared to foster the professional development of bedside nurses while simultaneously making a positive impact on disease management. Opportunity for future investigation includes efficacy of teaching tools on diabetes mastery, the effect of clinical nurse specialist mentoring on a select group of bedside nurses, and the Diabetes Management Mentor's impact on prevention of near-miss events.

  17. Quality Oncology Practice Initiative Certification Program: measuring implementation of chemotherapy administration safety standards in the outpatient oncology setting.

    Gilmore, Terry R; Schulmeister, Lisa; Jacobson, Joseph O

    2013-03-01

    The Quality Oncology Practice Initiative (QOPI) Certification Program (QCP) evaluates individual outpatient oncology practice performance in areas that affect patient care and safety and builds on the American Society of Clinical Oncology (ASCO) QOPI by assessing the compliance of a practice with certification standards based on the ASCO/Oncology Nursing Society standards for safe chemotherapy administration. To become certified, a practice must attain a benchmark quality score on certification measures in QOPI and attest that it complies with 17 QCP standards. Structured on-site reviews, initially performed in randomly selected practices, became mandatory beginning in September 2011. Of 111 practices that have undergone on-site review, only two were fully concordant with all of the standards (median, 11; range, seven to 17). Most practices were subsequently able to modify practice to become QOPI certified. The QCP addresses the call from the Institute of Medicine to close the quality gap by aligning evidence-based guidelines and consensus-driven standards with requirements for oncology practices to develop and maintain structural safety components, such as policies and procedures that ensure practice performance. On-site practice evaluation is a high-impact component of the program.

  18. EPA program to demonstrate mitigation measures for indoor radon: initial results

    Henschel, D.B.; Scott, A.G.

    1986-01-01

    EPA has installed radon mitigation techniques in 18 concrete block basement homes in the Reading Prong region of eastern Pennsylvania. Three alternative active soil ventilation approaches were tested: suction on the void network within the concrete block basement walls; suction on the footing drain tile system; and suction on the aggregate underneath the concrete slab. The initial 18 mitigation installations were designed to demonstrate techniques which would have low to moderate installation and operating costs. Where effective closure of major openings in the block walls is possible, suction on the wall voids has proved to be extremely effective, able to reduce homes having very high radon Working Levels (up to 7 WL) to 0.02 WL and less. However, where inaccessible major openings are concealed within the wall, it is more difficult and/or more expensive to develop adequate suction on the void network, and performance is reduced. Testing is continuing to demonstrate the steps required to achieve high performance with wall suction in homes with such difficult-to close walls. Drain tile suction can be very effective where the drain tiles completely surround the home; drain tile suction is the least expensive and most aesthetic of the active soil ventilation approaches, but appears susceptible to spikes in radon levels when the basement is depressurized. Sub-slab suction as tested in this study - with one or two individual suction points in the slab - does not appear adequate to ensure sustained high levels of reduction on block wall basement homes; it appears to effectively treat slab-related soil gas entry routes so long as a uniform layer of aggregate is present, but it does not appear to effectively treat the wall-related entry routes. Closure of major openings might have improved sub-slab suction performance. 5 figures, 3 tables

  1. Initial employment experiences of 1997 graduates of radiation oncology training programs

    International Nuclear Information System (INIS)

    Bushee, Gerald R.; Sunshine, Jonathan H.; Simon, Carol; Schepps, Barbara

    2001-01-01

    Purpose: To inform the profession of current trends in the job market, the American College of Radiology (ACR) sought to detail the job-hunting experiences and outcomes of 1997 graduates of radiation oncology training programs. Methods and Materials: In early 1998, questionnaires were mailed to all graduates; 67% responded. Results were compared with similar surveys of 1996 graduates. Results: Similar to past years, immediately after graduation, 13% of residency graduates and 1 of 10 fellowship graduates encountered serious employment difficulties - that is, spent some time working locums, working outside radiation oncology, or unemployed. By 6-12 months after graduation, approximately 2% of all residency graduates were working outside the profession and approximately 3% were not working at all. Eighty-five percent of residency graduates and 7 of 8 fellowship graduates reported that their employment reasonably matched their training and individual goals. On average, graduates' actual salaries approximately corresponded to expected salaries. Eleven percent of all graduates were in nonownership-track jobs, a significant decline since 1996. For residents and fellows combined, 46% had a job with at least one characteristic some observers associate with a weak job market, but fewer than half of those with one of these characteristics actually disliked it. These percentages are similar to 1996. Women graduates were more likely than men to have spouse-related restrictions on job location but less likely to end up in a self-reportedly undesirable location. Conclusion: Unemployment remained low. Some other indicators of the employment market showed improvement, while others did not

    Deep-sea coral and sponge ecosystems are widespread throughout most of Alaska’s marine waters. In some places, such as the central and western Aleutian Islands, deep-sea coral and sponge resources can be extremely diverse and may rank among the most abundant deep-sea coral and sponge communities in the world. Many different species of fishes and invertebrates are associated with deep-sea coral and sponge communities in Alaska. Because of their biology, these benthic invertebrates are potentially impacted by climate change and ocean acidification. Deepsea coral and sponge ecosystems are also vulnerable to the effects of commercial fishing activities. Because of the size and scope of Alaska’s continental shelf and slope, the vast majority of the area has not been visually surveyed for deep-sea corals and sponges. NOAA’s Deep Sea Coral Research and Technology Program (DSCRTP) sponsored a field research program in the Alaska region between 2012–2015, referred to hereafter as the Alaska Initiative. The priorities for Alaska were derived from ongoing data needs and objectives identified by the DSCRTP, the North Pacific Fishery Management Council (NPFMC), and Essential Fish Habitat-Environmental Impact Statement (EFH-EIS) process.This report presents the results of 15 projects conducted using DSCRTP funds from 2012-2015. Three of the projects conducted as part of the Alaska deep-sea coral and sponge initiative included dedicated at-sea cruises and fieldwork spread across multiple years. These projects were the eastern Gulf of Alaska Primnoa pacifica study, the Aleutian Islands mapping study, and the Gulf of Alaska fish productivity study. In all, there were nine separate research cruises carried out with a total of 109 at-sea days conducting research. The remaining projects either used data and samples collected by the three major fieldwork projects or were piggy-backed onto existing research programs at the Alaska Fisheries Science Center (AFSC).

    required confidence level. In order to address uncertainty propagation in analysis and methods in the HTGR community the IAEA initiated a Coordinated Research Project (CRP) on the HTGR Uncertainty Analysis in Modelling (UAM) that officially started in 2013. Although this project focuses specifically on the peculiarities of HTGR designs and its simulation requirements, many lessons can be learned from the LWR community and the significant progress already made towards a consistent methodology uncertainty analysis. In the case of LWRs the NRC has already in 1988 amended 10 CFR 50.46 to allow best-estimate (plus uncertainties) calculations of emergency core cooling system performance. The Nuclear Energy Agency (NEA) of the Organization for Economic Co-operation and Development (OECD) also established an Expert Group on "Uncertainty Analysis in Modelling" which finally led to the definition of the "Benchmark for Uncertainty Analysis in Modelling (UAM) for Design, Operation and Safety Analysis of LWRs". The CRP on HTGR UAM will follow as far as possible the on-going OECD Light Water Reactor UAM benchmark activity.

    In this paper we experimentally demonstrated a broadband scheme of the multiresonator quantum memory-interface. The microwave photonic scheme consists of the system of mini-resonators strongly interacting with a common broadband resonator coupled with the external waveguide. We have implemented the impedance matched quantum storage in this scheme via controllable tuning of the mini-resonator frequencies and coupling of the common resonator with the external waveguide. Proof-of-principal experiment has been demonstrated for broadband microwave pulses when the quantum efficiency of 16.3% was achieved at room temperature. By using the obtained experimental spectroscopic data, the dynamics of the signal retrieval has been simulated and promising results were found for high-Q mini-resonators in microwave and optical frequency ranges. The results pave the way for the experimental implementation of broadband quantum memory-interface with quite high efficiency η > 0.99 on the basis of modern technologies, including optical quantum memory at room temperature.

  11. Repetition priming of motor activity mediated by a central pattern generator: the importance of extrinsic vs. intrinsic program initiators

    Repetition priming is characterized by increased performance as a behavior is repeated. Although this phenomenon is ubiquitous, mediating mechanisms are poorly understood. We address this issue in a model system, the feeding network of Aplysia. This network generates both ingestive and egestive motor programs. Previous data suggest a chemical coding model: ingestive and egestive inputs to the feeding central pattern generator (CPG) release different modulators, which act via different second messengers to prime motor activity in different ways. The ingestive input to the CPG (neuron CBI-2) releases the peptides feeding circuit activating peptide and cerebral peptide 2, which produce an ingestive pattern of activity. The egestive input to the CPG (the esophageal nerve) releases the peptide small cardioactive peptide. This model is based on research that focused on a single aspect of motor control (radula opening). Here we ask whether repetition priming is observed if activity is triggered with a neuron within the core CPG itself and demonstrate that it is not. Moreover, previous studies demonstrated that effects of modulatory neurotransmitters that induce repetition priming persist. This suggests that it should be possible to “prime” motor programs triggered from within the CPG by first stimulating extrinsic modulatory inputs. We demonstrate that programs triggered after ingestive input activation are ingestive and programs triggered after egestive input activation are egestive. We ask where this priming occurs and demonstrate modifications within the CPG itself. This arrangement is likely to have important consequences for “task” switching, i.e., the cessation of one type of motor activity and the initiation of another. PMID:27466134

    2014-01-01

    ABSTRACT Background: The Nigerian Urban Reproductive Health Initiative (NURHI), a 6-year comprehensive family planning program (2009–2015) in 4 cities, intentionally applies communication theories to all program elements, not just the demand generation ones, relying mainly on a theory called ideation—the concept that contraceptive use is influenced by people's beliefs, ideas, and feelings and that changing these ideational factors can change people's behavior. Program Description: The project used multiple communication channels to foster dialogue about family planning, increase social approval for it, and improve accurate knowledge about contraceptives. Mobile service delivery was started in the third year to improve access to clinical methods in slums. Methods: Data from representative baseline (2010–11) and midterm (2012) surveys of women of reproductive age in the project cities were analyzed. We also used propensity score matching to create a statistically equivalent control group of women not exposed to project activities, and we examined service delivery data from NURHI-supported clinics (January 2011–May 2013) to determine the contribution of mobile services to total family planning services. Results: Three years into the initiative, analysis of longitudinal data shows that use of modern contraceptives has increased in each city, varying from 2.3 to 15.5 percentage points, and that the observed increases were predicted by exposure to NURHI activities. Of note is that modern method use increased substantially among the poorest wealth quintiles in project cities, on average, by 8.4 percentage points. The more project activities women were exposed to, the greater their contraceptive use. For example, among women not using a modern method at baseline, contraceptive prevalence among those with no exposure by midterm was 19.1% vs. 43.4% among those with high exposure. Project exposure had a positive dose-response relationship with ideation, as did

    When one considers broadband, the Internet immediately springs to mind. However, broadband is impacting society in many ways. For instance, broadband networks can be used to deliver healthcare or community related services to individuals who don't have computers, have distance as an issue to contend with, or don't use the internet. Broadband can support better management of scarce energy resources with the advent of smart grids, enables improved teleworking capacity and opens up a world of new entertainment possibilities. Yet scholarly examinations of broadband technology have so far examin

    Implementation of major organizational change initiatives presents a challenge for long-term care leadership. Implementation of the INTERACT® (Interventions to Reduce Acute Care Transfers) quality improvement program, designed to improve the management of acute changes in condition and reduce unnecessary emergency department visits and hospitalizations of nursing home residents, serves as an example to illustrate the facilitators and barriers to major change in long-term care. As part of a larger study of the impact of INTERACT® on rates of emergency department visits and hospitalizations, staff of 71 nursing homes were called monthly to follow-up on their progress and discuss successful facilitating strategies and any challenges and barriers they encountered during the yearlong implementation period. Themes related to barriers and facilitators were identified. Six major barriers to implementation were identified: the magnitude and complexity of the change (35%), instability of facility leadership (27%), competing demands (40%), stakeholder resistance (49%), scarce resources (86%), and technical problems (31%). Six facilitating strategies were also reported: organization-wide involvement (68%), leadership support (41%), use of administrative authority (14%), adequate training (66%), persistence and oversight on the part of the champion (73%), and unfolding positive results (14%). Successful introduction of a complex change such as the INTERACT® quality improvement program in a long-term care facility requires attention to the facilitators and barriers identified in this report from those at the frontline.

  15. Local government broadband policies for areas with limited Internet access

    2014-03-01

    Full Text Available Despite their wide diffusion in developed countries, broadband services are still limited in areas where providing them is not profitable for private telecom carriers. To address this, many local governments in Japan have implemented broadband deployment projects subsidized by the national government. In this paper, we discuss local government broadband policies based on survey data collected from municipalities throughout the country. With the support of national promotion policies, broadband services were rapidly introduced to most local municipalities in Japan during the 2000s. Local government deployment policies helped to reduce the number of areas with no broadband access. A business model based on the Indefeasible Right of Use (IRU contract between a private telecom carrier and a local government has been developed in recent years. Even local governments without the technical capacity to operate a broadband business can introduce broadband services into their territory using the IRU business model.

    Background The Nigerian Antiretroviral therapy (ART) program started in 2004 and now ranks among the largest in Africa. However, nationally representative data on outcomes have not been reported. Methods We evaluated retrospective cohort data from a nationally representative sample of adults aged ≥15 years who initiated ART during 2004 to 2012. Data were abstracted from 3,496 patient records at 35 sites selected using probability-proportional-to-size (PPS) sampling. Analyses were weighted and controlled for the complex survey design. The main outcome measures were mortality, loss to follow-up (LTFU), and retention (the proportion alive and on ART). Potential predictors of attrition were assessed using competing risk regression models. Results At ART initiation, 66.4 percent (%) were females, median age was 33 years, median weight 56 kg, median CD4 count 161 cells/mm3, and 47.1% had stage III/IV disease. The percentage of patients retained at 12, 24, 36 and 48 months was 81.2%, 74.4%, 67.2%, and 61.7%, respectively. Over 10,088 person-years of ART, mortality, LTFU, and overall attrition (mortality, LTFU, and treatment stop) rates were 1.1 (95% confidence interval (CI): 0.7–1.8), 12.3 (95%CI: 8.9–17.0), and 13.9 (95% CI: 10.4–18.5) per 100 person-years (py) respectively. Highest attrition rates of 55.4/100py were witnessed in the first 3 months on ART. Predictors of LTFU included: lower-than-secondary level education (reference: Tertiary), care in North-East and South-South regions (reference: North-Central), presence of moderate/severe anemia, symptomatic functional status, and baseline weight ART initiation could improve program outcomes. Retention interventions targeting men and those with lower levels of education are needed. Further research to understand geographic and clinic size variations with outcome is warranted.

    Global environmental changes and other anthropogenic impacts are rapidly transforming the structure and functioning of ecosystems worldwide. These changes are leading to land degradation with an estimated 25 % of the global land surface being affected. Landscape-scale restoration of these degraded ecosystems has therefore been recognised globally as an international priority. In the resource-rich biodiverse semi-arid Pilbara region of north-west Western Australia hundreds of thousands of hectares are disturbed due to established and emerging iron-ore mine operations. At this scale, the need to develop cost-effective large-scale solutions to restore these landscapes becomes imperative to preserve biodiversity and achieve functionality and sustainability of these ecosystems. The Restoration Seedbank Initiative (RSB) (http://www.plants.uwa.edu.au/ research/restoration-seedbank-initiative) is a five-year multidisciplinary research project that aims to build knowledge and design strategies to restore mine-impacted landscapes in the Pilbara and other arid and semi-arid landscapes worldwide (Kildiseheva et al., 2016). The RSB comprises four research programs that focus on seedbank management and curation, seed storage, seed enhancement, and the use of alternative soil substrates (soil or growing medium program) respectively. These multi-disciplinary programs address the significant challenges of landscape scale restoration in arid systems. In the soil program we follow an integrated approach that includes the characterization of undisturbed ecosystems, assessment of restored soils with the use of soil quality indicators, and design of alternative soil substrates to support the establishment of native plant communities. A series of glasshouse studies and field trials have been conducted in the last three years to advance our knowledge on soil limitations and to provide solutions to effectively overcome these challenges in arid ecosystem restoration. These studies include

    The Doppler effect refers to the change in frequency of a wave source as a consequence of the relative motion between the source and an observer. Veselago theoretically predicted that materials with negative refractions can induce inverse Doppler effects. With the development of metamaterials, inverse Doppler effects have been extensively investigated. However, the ideal material parameters prescribed by these metamaterial design approaches are complex and also challenging to obtain experimentally. Here, we demonstrated a method of designing and experimentally characterising arbitrary broadband acoustic metamaterials. These omni-directional, double-negative, acoustic metamaterials are constructed with 'flute-like' acoustic meta-cluster sets with seven double meta-molecules; these metamaterials also overcome the limitations of broadband negative bulk modulus and mass density to provide a region of negative refraction and inverse Doppler effects. It was also shown that inverse Doppler effects can be detected in a flute, which has been popular for thousands of years in Asia and Europe.

  2. An ultra-broadband multilayered graphene absorber

    KAUST Repository

    Amin, Muhammad

    2013-01-01

    An ultra-broadband multilayered graphene absorber operating at terahertz (THz) frequencies is proposed. The absorber design makes use of three mechanisms: (i) The graphene layers are asymmetrically patterned to support higher order surface plasmon modes that destructively interfere with the dipolar mode and generate electromagnetically induced absorption. (ii) The patterned graphene layers biased at different gate voltages backedup with dielectric substrates are stacked on top of each other. The resulting absorber is polarization dependent but has an ultra-broadband of operation. (iii) Graphene\\'s damping factor is increased by lowering its electron mobility to 1000cm 2=Vs. Indeed, numerical experiments demonstrate that with only three layers, bandwidth of 90% absorption can be extended upto 7THz, which is drastically larger than only few THz of bandwidth that can be achieved with existing metallic/graphene absorbers. © 2013 Optical Society of America.

    A new type of broadband active electrically small antenna (ESA) based on superconducting quantum arrays (SQAs) has been proposed and developed. These antennas are capable of providing both sensing and amplification of broadband electromagnetic signals with a very high spurious-free dynamic range (SFDR)—up to 100 dB (and even more)—with high sensitivity. The frequency band can range up to tens of gigahertz, depending on Josephson junction characteristic frequency, set by fabrication. In this paper we review theoretical and experimental studies of SQAs and SQA-based antenna prototypes of both transformer and transformer-less types. The ESA prototypes evaluated were fabricated using a standard Nb process with critical current density 4.5 kA cm-2. Measured device characteristics, design issues and comparative analysis of various ESA types, as well as requirements for interfaces, are reviewed and discussed.

    For a broadband-operated RSE interferometer, a simple and smart length sensing and control scheme was newly proposed. The sensing matrix could be diagonal, owing to a simple allocation of two RF modulations and to a macroscopic displacement of cavity mirrors, which cause a detuning of the RF modulation sidebands. In this article, the idea of the sensing scheme and an optimization of the relevant parameters will be described

  9. Society Influencing Science: The role of the Transdisciplinary Advisory Board (TAB) of the European Joint Programming Initiative on Climate.

    2017-12-01

    It is becoming increasingly apparent that the separation between science and the rest of society is not helping us find solutions to "wicked" problems like climate change or achieving the Sustainable Development Goals. It is clear that a broader approach to research is necessary - one that includes stakeholders in the research process itself. What is unclear is how best to do this. The Transdisciplinary Advisory Board (TAB) of the European Joint Programming Initiative on Climate (JPI Climate) is an example of scientists and stakeholders working together to frame climate research and move the results of scientific research into decision support. JPI Climate is a consortium of 12 European countries (with partners from nine more countries) and is a major funding channel and forum for climate research in Europe. The TAB has an equal number of stakeholders and researchers from 10 different European countries, has an even gender balance, and its members have widely differing backgrounds. The TAB provides input and advice to the governing board of JPI Climate, and influences both the strategic planning for this funding initiative as well as specific calls for proposals issued through the consortium. In addition to its advisory role, the TAB explores the transdisciplinary process itself, expanding the boundaries of how stakeholders and science can interact positively. The TAB is a two-way mechanism through which stakeholders can help improve research and science can help improve society. We will give examples of the spectrum of how the TAB provides mutual influence between stakeholders and science - from helping to draft 10-year research strategies to helping advance the uptake of climate research into the private and policy sectors.

    The goal of the Hypertension Management Initiative (HMI) is to improve the management and control of hypertension by both primary care providers and patients. The HMI was in effect in 11 primary care sites across the province of Ontario, Canada. This was a qualitative study. Focus groups and a lobby survey were completed with a total of 199 of the 3934 patients enrolled in the study. Interviews with 41 participating health care providers from all sites were performed. A qualitative description approach was used to give a rich description of each informant's experiences. Patients expressed motivation and engagement in their own health care and became more knowledgeable about hypertension and how to manage it with their health care providers. Most reported satisfaction with the discipline of regular appointments and ongoing monitoring and counseling of the program including identifying and working on goals for their modifiable risk factors. Their health care providers felt the HMI program had a positive impact on the treatment and management of hypertension and also that it improved the functioning of the interprofessional team. The HMI helped to improve patient self-empowerment and self-management and also improved physicians' and nurses' confidence in diagnosing accurately and in hypertension management. Physician buy-in is key to maintaining clinical hypertension management. Interprofessional collaboration was improved for physicians and nurses but less so for pharmacists. Greater confidence among the nurses to manage hypertension more independently reduced demands on physician time. Copyright © 2013 Canadian Cardiovascular Society. Published by Elsevier Inc.

    2015-01-01

    The broadband component of fan noise has grown in relevance with an increase in bypass ratio and incorporation of advanced fan designs. Therefore, while the attenuation of fan tones remains a major factor in engine nacelle acoustic liner design, the simultaneous reduction of broadband fan noise levels has received increased interest. As such, a previous investigation focused on improvements to an established broadband acoustic liner optimization process using the Advanced Noise Control Fan (ANCF) rig as a demonstrator. Constant-depth, double-degree of freedom and variable-depth, multi-degree of freedom liner designs were carried through design, fabrication, and testing. This paper addresses a number of areas for further research identified in the initial assessment of the ANCF study. Specifically, incident source specification and uncertainty in some aspects of the predicted liner impedances are addressed. This information is incorporated in updated predictions of the liner performance and comparisons with measurement are greatly improved. Results illustrate the value of the design process in concurrently evaluating the relative costs/benefits of various liner designs. This study also provides further confidence in the integrated use of duct acoustic propagation/radiation and liner modeling tools in the design and evaluation of novel broadband liner concepts for complex engine configurations.

    Lesbian, gay, bisexual, and transgender (LGBT) youth experience multiple sexual health inequities driven, in part, by deficits in parental and peer support, school-based sex education programs, and community services. Research suggests that the Internet may be an important resource in the development of sexual health among LGBT youth. We examined the feasibility of recruiting youth in same-sex relationships into an online sexual health intervention, evaluated intervention acceptability, and obtained initial estimates of intervention efficacy. LGBT youth (16 to 20 years old) completed Queer Sex Ed (QSE), an online, multimedia sexual health intervention consisting of five modules. The final sample (N = 202) completed the pretest, intervention, and posttest assessments. The primary study outcomes were sexual orientation identity and self-acceptance (e.g., coming-out self-efficacy), sexual health knowledge (e.g., sexual functioning), relationship variables (e.g., communication skills), and safer sex (e.g., sexual assertiveness). Analyses indicated that 15 of the 17 outcomes were found to be significant (p LGBT youth.

    The purpose of this study was to investigate the relationship between: (1) children's caries score (dmft, DMFT) at the time of sealant placement; and (2) "success" (measured as being caries-free) of that tooth at follow-up visits. An existing database of over 38,000 sealants (10,038 children) placed between 1997 and 2002 by the Jefferson County Health Department's Community Based Sealant Program, Birmingham, Ala, was used in the analysis. Only children returning for followup visits after the initial placement of the sealants were included in this study, resulting in 6,452 sealants (2,097 children). Logistic regression analysis was performed to determine the differences in sealant success between children with a dmft score of 0 vs a dmft score of >0 at baseline, and a DMFT score of 0 vs a DMFT score of >0 at baseline. In the permanent and primary dentitions, those who had no caries at the time of sealant placement (dmft/DMFT=0) had a significantly higher success of sealants during years 1 to 5 compared to those with a caries score of greater than 0 (dmft/DMFT>0; P<.023, P<.002, respectively). Children with previous caries experience may be at a higher risk for sealant "failure" (measured as caries on a tooth surface previously sealed) after 1 year and, therefore, may require more diligent sealant maintenance.

    2011-12-01

    Researchers at the Southern California Earthquake Center (SCEC) have developed the CyberShake computational platform to perform probabilistic seismic hazard analysis (PSHA) in the Los Angeles region (Graves et al., 2010) using deterministic wave propagation simulations at frequencies up to 0.5 Hz. CyberShake uses seismic reciprocity to calculate synthetic seismograms for a suite of more than 600,000 rupture realizations. From this set of seismograms we compute intensity measures, which are then combined into a PSHA hazard curve for the site of interest. SCEC has also developed the SCEC Broadband Ground Motion Simulation Platform, a software system that can calculate broadband seismograms at frequencies up to 10 Hz for historical and scenario earthquakes using multiple earthquake rupture generators, multiple low- and high-frequency wave propagation simulation codes, and multiple site effects modules. Here we report how we have integrated the high-frequency computational capabilities of the SCEC Broadband Platform into CyberShake, producing the Broadband CyberShake Platform. The Broadband CyberShake Platform extends the frequency range up to 10 Hz by combining low frequency deterministic synthetic seismograms with higher frequency stochastic seismograms. We can now calculate physics-based seismograms and PSHA hazard curves for intensity measures such as PGA that are strongly dependent on higher frequency ground motions. A potential benefit of this approach, particularly at higher frequencies, is that given adequate sampling of the parameter space, the physics-based model naturally limits the upper bound of the estimated ground motion response. This often leads to a reduction in hazard at longer return periods. We are applying the computational capabilities of the SCEC Broadband CyberShake Platform at southern California sites selected to support validation of this newly developed PSHA computational technique. This includes calculation of Broadband Cyber

    The Nigerian Urban Reproductive Health Initiative (NURHI), a 6-year comprehensive family planning program (2009-2015) in 4 cities, intentionally applies communication theories to all program elements, not just the demand generation ones, relying mainly on a theory called ideation-the concept that contraceptive use is influenced by people's beliefs, ideas, and feelings and that changing these ideational factors can change people's behavior. The project used multiple communication channels to foster dialogue about family planning, increase social approval for it, and improve accurate knowledge about contraceptives. Mobile service delivery was started in the third year to improve access to clinical methods in slums. Data from representative baseline (2010-11) and midterm (2012) surveys of women of reproductive age in the project cities were analyzed. We also used propensity score matching to create a statistically equivalent control group of women not exposed to project activities, and we examined service delivery data from NURHI-supported clinics (January 2011-May 2013) to determine the contribution of mobile services to total family planning services. Three years into the initiative, analysis of longitudinal data shows that use of modern contraceptives has increased in each city, varying from 2.3 to 15.5 percentage points, and that the observed increases were predicted by exposure to NURHI activities. Of note is that modern method use increased substantially among the poorest wealth quintiles in project cities, on average, by 8.4 percentage points. The more project activities women were exposed to, the greater their contraceptive use. For example, among women not using a modern method at baseline, contraceptive prevalence among those with no exposure by midterm was 19.1% vs. 43.4% among those with high exposure. Project exposure had a positive dose-response relationship with ideation, as did ideation and contraceptive use. By the end of the observation period

Through a series deploy experiment at seafloor offshore Taiwan that got a lot of data can be used to study plate tectonics, seismic activity, source characteristics. Nowadays they have pretty good results already. Due to bandwidth limitations of the Yardbird OBS that inadequate to use for analyze global-scale earthquake. Therefor developing broadband ocean bottom seismograph is an important goal for the development team. Currently the broadband OBS (called BBYB) design and construction have completed the initial experiment phase. Due to underwater instruments always got high risk. Something accidentally making equipment sank in the sea cannot be recovery. Even recovery of equipment may also be causing poor performance because there is no data record. It cannot be to accomplish the experiment mission.

    The State University Downstate Medical Center initiated a Master of Public Health (MPH) degree program in July 2001 following planning efforts that began in 1995. Twelve Students entered the program in June 2002. Currently, eighty students are enrolled in the program and eighteen have graduated from it in 2004 and 2005. With an initial focus on urban and immigrant health, the program aims to train public health professionals who can assist in addressing through population-based interventions the health issues of Brooklyn's 2,465,326 people, of whom 38.5% are immigrants to the United States. Starting with four courses in the summer 2002 semester, the program now offers twenty-four courses over the three semesters of the academic year. The program is housed in the Department of Preventive Medicine and Community Health of the College of Medicine and is part-time in nature for most students. In addition to completing required course work, students must also complete a 250-hour practicum experience in which they apply theoretical knowledge in a public health practice setting. Student practicum experiences play a vital role in linking the program to communities and serve as conduits for the initiation of further community based collaboratives. This article describes the challenges encountered in initiating an MPH program in an academic medical center, the importance of both intramural and community support to its success, and the vital role it plays in addressing the health issues of various communities. The program became a leading priority of the Strategic Plan of the Downstate Medical Center in 2000, and received the full support of Downstate's then new president, Dr. John C. LaRosa. This prioritization and support proved essential to the rapid development of the program. The Downstate MPH program offers a concurrent degree to medical students who are able to complete both degrees in a four year period. The Alumni Fund of the College of Medicine provides each MD

    Background Peer counseling (PC) has been associated with increased breastfeeding initiation and duration, but few analyses have examined the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) model for peer counseling or the continuation of breastfeeding from birth through 12 months postpartum. Objectives Identify associations between Minnesota WIC Peer Breastfeeding Support Program services and breastfeeding initiation and continuation. Methods Retrospective analysis of observational data from the Minnesota WIC program's administrative database of women who gave birth in 2012 and accepted a PC program referral prenatally (n = 2219). Multivariate logistic regression and Cox regression models examined associations between peer services and breastfeeding initiation and continuation of any breastfeeding. Results Among women who accepted referral into a PC program, odds of initiation were significantly higher among those who received peer services (Odds Ratio (OR): 1.66; 95% CI 1.19-2.32), after adjusting for confounders. Women who received peer services had a significantly lower hazard of breastfeeding discontinuation from birth through 12 months postpartum than women who did not receive services. (Hazard Ratio (HR) month one: 0.45; 95% CI 0.33-0.61; months two through twelve: 0.33; 95% CI 0.18-0.60). The effect of peer counseling did not differ significantly by race and ethnicity, taking into account mother's country of origin. Conclusion for practice Receipt of peer services was positively associated with breastfeeding initiation and continued breastfeeding from birth through 12 months postpartum. Making peer services available to more women, especially in communities with low initiation and duration, could improve maternal and child health in Minnesota.

    2018-03-01

    A study was undertaken to improve upon the prognosticative capability of Environment and Climate Change Canada's (ECCC) UV Index forecast model. An aspect of that work, and the topic of this communication, was to investigate the use of the four UV broadband surface irradiance fields generated by ECCC's Global Environmental Multiscale (GEM) numerical prediction model to determine the UV Index. The basis of the investigation involves the creation of a suite of routines which employ high-spectral-resolution radiative transfer code developed to calculate UV Index fields from GEM forecasts. These routines employ a modified version of the Cloud-J v7.4 radiative transfer model, which integrates GEM output to produce high-spectral-resolution surface irradiance fields. The output generated using the high-resolution radiative transfer code served to verify and calibrate GEM broadband surface irradiances under clear-sky conditions and their use in providing the UV Index. A subsequent comparison of irradiances and UV Index under cloudy conditions was also performed. Linear correlation agreement of surface irradiances from the two models for each of the two higher UV bands covering 310.70-330.0 and 330.03-400.00 nm is typically greater than 95 % for clear-sky conditions with associated root-mean-square relative errors of 6.4 and 4.0 %. However, underestimations of clear-sky GEM irradiances were found on the order of ˜ 30-50 % for the 294.12-310.70 nm band and by a factor of ˜ 30 for the 280.11-294.12 nm band. This underestimation can be significant for UV Index determination but would not impact weather forecasting. Corresponding empirical adjustments were applied to the broadband irradiances now giving a correlation coefficient of unity. From these, a least-squares fitting was derived for the calculation of the UV Index. The resultant differences in UV indices from the high-spectral-resolution irradiances and the resultant GEM broadband irradiances are typically within 0

    Telemedicina is a Spanish project that covers teleradiology and radiosurgery areas. This project is under the frame of the Spanish Broadband National Plan (PLANBA). The final technical tests are being ended over Ethernet and ATM and it is planned to get their first clinical results on February-96. Two pilots will be installed: one in Madrid linking two sites through a ATM network (provided by Telefonica, Spanish PTT) and a second one in Asturias (north of Spain) using ISDN primary access (2 Mbps). The system handles still images, voice and video records, scanned documents, text and slides allowing doctors to interchange this data using cooperative tools. The system is based on a multimedia Unix platform with voice, video and videoconference devices and boards. The platform will be used in several ways: as desktop videoconferencing, primary diagnosis and review. Communications are based on ATM (over AAL5) at 155 Mbps and ISDN (primary access). The protocol used in both networks is TCP/IP. The application is written in C++ (object oriented design and programming) and C. GUI is built under X-Windows and Motif. The codification of video is MJPEG done through dedicated hardware. The system is integrated in a small PACS (previously installed); the images are captured from the modalities such as CT using the DICOM standard and it is connected with the Radiological Information System. The application allows collaborative work: telepointer, shared windows, editors and actions. Main news of the Telemedicina project will be the incorporation of broadband networks (ATM at 155 Mbps) and the integration of collaborative work. This two aspects allow the doctors to improve their work speeding up the transmission and retrieval of medical records. Also this platform can be used to achieve several goals: such as primary diagnosis, videoconference, review.

    Interferometers enable ultrasensitive measurement in a wide array of applications from gravitational wave searches to force microscopes. The role of quantum mechanics in the metrological limits of interferometers has a rich history, and a large number of techniques to surpass conventional limits have been proposed. In a typical measurement configuration, the trade-off between the probe's shot noise (imprecision) and its quantum backaction results in what is known as the standard quantum limit (SQL). In this work, we investigate how quantum correlations accessed by modifying the readout of the interferometer can access physics beyond the SQL and improve displacement sensitivity. Specifically, we use an optical cavity to probe the motion of a silicon nitride membrane off mechanical resonance, as one would do in a broadband displacement or force measurement, and observe sensitivity better than the SQL dictates for our quantum efficiency. Our measurement illustrates the core idea behind a technique known as variational readout, in which the optical readout quadrature is changed as a function of frequency to improve broadband displacement detection. And, more generally, our result is a salient example of how correlations can aid sensing in the presence of backaction.

    2011-01-01

    The contributions from lossy and inductive vacuum chamber components to the broadband impedance of the NESTOR storage ring are obtained by using both low-frequency analytical approaches and computer simulations. As was expected considering the small ring circumference (15.44m), the main contributions both to the longitudinal impedance Z || /n and the loss factor k loss come from the RF-cavity. Cavity impedance was also estimated with CST Microwave Studio (CST Studio Suite TM 2006) by simulating coaxial wire method commonly used for impedance measurements. Both estimates agree well. Finally, we performed the simulations of a number of inductive elements with CST Particle Studio 2010 by using wake field solver. We have also evaluated the bunch length in NESTOR taking the conservative estimate of 3 Ohm for the ring broadband impedance and have found that the bunch length s z = 0.5 cm could be obtained in steady state operation mode for the designed bunch current of 10 mA and RF-voltage of 250 kV.

  11. Reflective afocal broadband adaptive optics scanning ophthalmoscope

    2011-01-01

    A broadband adaptive optics scanning ophthalmoscope (BAOSO) consisting of four afocal telescopes, formed by pairs of off-axis spherical mirrors in a non-planar arrangement, is presented. The non-planar folding of the telescopes is used to simultaneously reduce pupil and image plane astigmatism. The former improves the adaptive optics performance by reducing the root-mean-square (RMS) of the wavefront and the beam wandering due to optical scanning. The latter provides diffraction limited performance over a 3 diopter (D) vergence range. This vergence range allows for the use of any broadband light source(s) in the 450-850 nm wavelength range to simultaneously image any combination of retinal layers. Imaging modalities that could benefit from such a large vergence range are optical coherence tomography (OCT), multi- and hyper-spectral imaging, single- and multi-photon fluorescence. The benefits of the non-planar telescopes in the BAOSO are illustrated by resolving the human foveal photoreceptor mosaic in reflectance using two different superluminescent diodes with 680 and 796 nm peak wavelengths, reaching the eye with a vergence of 0.76 D relative to each other.

    Full Text Available Adopsi teknologi internet broadband dapat memberikan dampak ekonomi bagi masyarakat perbatasan. Karenanya pemerataan pembangunan internet broadband di wilayah  ini harus segera diwujudkan. Penelitian deskriptif kuantitatif ini dilaksanakan di wilayah perbatasan Provinsi Sulawesi Utara untuk mengetahui kondisi aspek supply dan demand perkembangan internet broadband di wilayah tersebut. Berdasarkan hasil penelitian, dapat disimpulkan bahwa dari aspek supply, kondisi infrastruktur masih sangat kurang, ketersediaan layanan internet broadband berkualitas tinggi dengan tarif rendah juga masih sulit diwujudkan. Dari aspek demand, stigma atau persepsi masyarakat bahwa internet tidak penting menjadi salah satu faktor penyebab tidak memiliki akses internet. Adapun hambatan yang paling dominan adalah ketidakpahaman dalam penggunaan internet. Faktor ini juga menjadi mendasari literasi internet broadband masyarakat pada level 0 yaitu  tidak peduli akan pentinya internet. Menanggapai kondisi ini, penyusunan dan penetapan kebijakan serta regulasi seperti QoS layanan, tarif interkoneksi, infrastructure sharing dibuat untuk menyediakan internet broadband berkualitas tinggi dengan harga murah.

    An ongoing SDSS reverberation mapping (RM) program (Shen et al. 2015) provides significantly improved black hole mass estimates for a large sample of QSOs out to redshift ˜3 in a single 7 square degree field. A recently approved large XMM-Newton program will complete the X-ray coverage of the field, contributing to a unique legacy sample of hundreds of QSOs with accurately measured bolometric luminosity, spectral energy distributions, Eddington ratios and variability properties. As illustration, we present here the X-ray spectral properties of the RM-QSOs derived from the analysis of all existing XMM-Newton and deep Chandra (AEGIS field) observations of the field. Taking advantage of the unprecedented multi-band, multi-epoch imaging and spectroscopy provided by the SDSS-RM campaign, the Pan-STARRS1 medium deep survey and the GALEX time domain survey we study in detail their instantaneous broadband spectral energy distributions to obtain accurate measures of the bolometric luminosity and to test accretion disk models. This data set allows us to dissect correlations between optical/X-ray spectral properties with black hole mass and Eddington ratio, as well as to constrain evolution of the radiative efficiency providing a first handle on black hole spin evolution in a large, statistical sample of AGN.

    The Next Accreditation System and the Clinical Learning Environment Review Program will emphasize practice-based learning and improvement and systems-based practice. We present the results of a survey of general surgery program directors to characterize the current state of quality improvement in graduate surgical education and introduce the Quality In-Training Initiative (QITI). In 2012, a 20-item survey was distributed to 118 surgical residency program directors from ACS NSQIP-affiliated hospitals. The survey content was developed in collaboration with the QITI to identify program director opinions regarding education in practice-based learning and improvement and systems-based practice, to investigate the status of quality improvement education in their respective programs, and to quantify the extent of resident participation in quality improvement. There was a 57% response rate. Eighty-five percent of program directors (n = 57) reported that education in quality improvement is essential to future professional work in the field of surgery. Only 28% (n = 18) of programs reported that at least 50% of their residents track and analyze their patient outcomes, compare them with norms/benchmarks/published standards, and identify opportunities to make practice improvements. Program directors recognize the importance of quality improvement efforts in surgical practice. Subpar participation in basic practice-based learning and improvement activities at the resident level reflects the need for support of these educational goals. The QITI will facilitate programmatic compliance with goals for quality improvement education. Copyright © 2013 American College of Surgeons. All rights reserved.

    To explore motivational factors for initiating, implementing, and maintaining physical activity following a rehabilitation program for patients with type 2 diabetes mellitus. Semi-structured, individual, qualitative interviews with five informants from the InterWalk trial were conducted at three separate occasions; at initiation of the rehabilitation program, at completion of the 12-week program, and 52 weeks after enrolment. Interviews were audio-recorded, transcribed, and analyzed according to Systematic Text Condensation. The framework of Self-Determination Theory was applied to guide analysis after identification of preliminary themes. Commitment and obligation were emphasized as being motivational in initiating physical activity. Toward the termination of the program, this was challenged by an expressed need for autonomy. Successful behavioral change was characterized by transfer of commitment to a new structure in everyday life, which also honored the request for autonomy. Feeling capable of participating in physical activity was facilitated through knowledge, practical experience, and progress and considered motivational, whereas lack of progress extinguished motivation. Finally, enjoyment of the activity was determining for long-term maintenance of physical activity behavior. Satisfaction of innate psychological needs leads to more autonomous regulation of behavior and, through this study, we investigated determining factors for extrinsically motivated behavior and factors of importance to the internalization process.

    Coudreuse, Jean-Pierre; Pautonnier, Sophie; Lavillonnière, Eric; Didierjean, Sylvain; Hilt, Benoît; Kida, Toshimichi; Oshima, Kazuyoshi

    This paper provides insights on the status of broadband optical access market and technologies in Europe and on the expected trends for the next generation optical access networks. The final target for most operators, cities or any other player is of course FTTH (Fibre To The Home) deployment although we can expect intermediate steps with copper or wireless technologies. Among the two candidate architectures for FTTH, PON (Passive Optical Network) is by far the most attractive and cost effective solution. We also demonstrate that Ethernet based optical access network is very adequate to all-IP networks without any incidence on the level of quality of service. Finally, we provide feedback from a FTTH pilot network in Colmar (France) based on Gigabit Ethernet PON technology. The interest of this pilot lies on the level of functionality required for broadband optical access networks but also on the development of new home network configurations.

    Morin, Bruce L.

    2010-01-01

    Pratt & Whitney has developed a Broadband Fan Noise Prediction System (BFaNS) for turbofan engines. This system computes the noise generated by turbulence impinging on the leading edges of the fan and fan exit guide vane, and noise generated by boundary-layer turbulence passing over the fan trailing edge. BFaNS has been validated on three fan rigs that were tested during the NASA Advanced Subsonic Technology Program (AST). The predicted noise spectra agreed well with measured data. The predicted effects of fan speed, vane count, and vane sweep also agreed well with measurements. The noise prediction system consists of two computer programs: Setup_BFaNS and BFaNS. Setup_BFaNS converts user-specified geometry and flow-field information into a BFaNS input file. From this input file, BFaNS computes the inlet and aft broadband sound power spectra generated by the fan and FEGV. The output file from BFaNS contains the inlet, aft and total sound power spectra from each noise source. This report is the third volume of a three-volume set documenting the Broadband Fan Noise Prediction System: Volume 1: Setup_BFaNS User s Manual and Developer s Guide; Volume 2: BFaNS User s Manual and Developer s Guide; and Volume 3: Validation and Test Cases. The present volume begins with an overview of the Broadband Fan Noise Prediction System, followed by validation studies that were done on three fan rigs. It concludes with recommended improvements and additional studies for BFaNS.

    1992-03-01

    The Girls Incorporated, formerly Girls Clubs of America, program in Preventing Adolescent Pregnancy, which was initiated in 1985, was evaluated to obtain information about sexual behavior and attitudes related to pregnancy, educational and career expectations, and sociodemographic characteristics, and to ascertain the effectiveness of 2 components for girls aged 12-14 in delaying early sexual involvement. The theoretical base of intervention is discussed and delineation of 3 themes recurrent in the literature. Program interventions are also described. The 2 program components evaluated were Will Power/Won't Power which taught skill in general and specific assertiveness, and Growing Together, which facilitated communication between parents and daughters. The sample consisted of 412 virgin girls 12-14 years, of which 25% did not participate in either program, from communities in which the adolescent pregnancy rate was higher than the national average. Participants were required to have completed 1 complete year which included before and after surveys. 257 participated in Will Power/Won't Power; 84 in Growing Together; and 46 in both programs. Participants and nonparticipants were similar in background characteristics. The profile was one of primarily African American 12 year olds of a Protestant religion. Growing Together participants were slightly different and less likely to engage in early sexual intercourse. The findings of the bivariate and logistic regression analyses were that nonparticipants were 2.5 times more likely to initiate sexual intercourse during the study year than participants in Growing Together, but this was only marginally statistically significant. It is suggested however that when controlling for age, religion, race and having contact with a pregnant teen that Growing Together participation contributed to a delay in the initiation of sexual intercourse. Participation in Will Power did not account for any differences in likelihood of initiating

    Fu, Congyi; Wang, Bohan; Zhao, Tianfei; Chen, C. Q.

    2018-01-01

    Energy transmission efficiency and working bandwidth are the two major factors limiting the application of current acoustic diodes (ADs). This letter presents a design of high efficiency and broadband acoustic diodes composed of a nonlinear frequency converter and a linear wave filter. The converter consists of two masses connected by a bilinear spring with asymmetric tension and compression stiffness. The wave filter is a linear mass-spring lattice (sonic crystal). Both numerical simulation and experiment show that the energy transmission efficiency of the acoustic diode can be improved by as much as two orders of magnitude, reaching about 61%. Moreover, the primary working band width of the AD is about two times of the cut-off frequency of the sonic crystal filter. The cut-off frequency dependent working band of the AD implies that the developed AD can be scaled up or down from macro-scale to micro- and nano-scale.

    Tunable complementary split ring resonators (CSRRs) based on monolayer graphene are presented in terahertz regime. By applying different gate voltage, the Fermi level and optical conductivity of monolayer graphene pattern can be changed. Here, we employ a numerical simulation to study the interaction of light with graphene CSRRs. The results indicate that the extinction in transmission becomes stronger, and the resonance frequency presents blue shift with higher Fermi level of the graphene pattern. Three pronounced resonant peaks appear which can be modulated dynamically in the range of 1-2THz and 3-7THz, and realizing dynamic broadband terahertz modulation, the modulation depth exceeds 85% at all three resonant peaks, the highest modulation depth reaches 98.8% at 7.47THz.

    Broadband laser ranging combines spectral interferometry and a dispersive Fourier transform to achieve high-repetition-rate measurements of the position of a moving surface. Telecommunications fiber is a convenient tool for generating the large linear dispersions required for a dispersive Fourier transform, but standard fiber also has higher-order dispersion that distorts the Fourier transform. Imperfections in the dispersive Fourier transform significantly complicate the ranging signal and must be dealt with to make high-precision measurements. We describe in detail an analysis process for interpreting ranging data when standard telecommunications fiber is used to perform an imperfect dispersive Fourier transform. This analysis process is experimentally validated over a 27-cm scan of static positions, showing an accuracy of 50 μm and a root-mean-square precision of 4.7 μm.

    Lam, Daniel; Fard, Ali M; Buckley, Brandon; Jalali, Bahram

    2013-02-15

    We present a digital postprocessing linearization technique to efficiently suppress dynamic distortions added to a wideband signal in an analog optical link. Our technique achieves up to 35 dB suppression of intermodulation distortions over multiple octaves of signal bandwidth. In contrast to conventional linearization methods, it does not require excessive analog bandwidth for performing digital correction. This is made possible by regenerating undesired distortions from the captured output, and subtracting it from the distorted digitized signal. Moreover, we experimentally demonstrate a record spurious-free dynamic range of 120 dB·Hz(2/3) over a 6 GHz electrical signal bandwidth. While our digital broadband linearization technique advances state-of-the-art optical links, it can also be applied to other nonlinear dynamic systems.

    Polat, Emre O; Kocabas, Coskun

    2013-01-01

    Optical modulators are commonly used in communication and information technology to control intensity, phase, or polarization of light. Electro-optic, electroabsorption, and acousto-optic modulators based on semiconductors and compound semiconductors have been used to control the intensity of light. Because of gate tunable optical properties, graphene introduces new potentials for optical modulators. The operation wavelength of graphene-based modulators, however, is limited to infrared wavelengths due to inefficient gating schemes. Here, we report a broadband optical modulator based on graphene supercapacitors formed by graphene electrodes and electrolyte medium. The transparent supercapacitor structure allows us to modulate optical transmission over a broad range of wavelengths from 450 nm to 2 μm under ambient conditions. We also provide various device geometries including multilayer graphene electrodes and reflection type device geometries that provide modulation of 35%. The graphene supercapacitor structure together with the high-modulation efficiency can enable various active devices ranging from plasmonics to optoelectronics.

  16. Frequency Doubling Broadband Light in Multiple Crystals

    International Nuclear Information System (INIS)

    Alford, William J.; Smith, Arlee V.

    2000-01-01

    The authors compare frequency doubling of broadband light in a single nonlinear crystal with doubling in five crystals with intercrystal temporal walk off compensation, and with doubling in five crystals adjusted for offset phase matching frequencies. Using a plane-wave, dispersive numerical model of frequency doubling they study the bandwidth of the second harmonic and the conversion efficiency as functions of crystal length and fundamental irradiance. For low irradiance the offset phase matching arrangement has lower efficiency than a single crystal of the same total length but gives a broader second harmonic bandwidth. The walk off compensated arrangement gives both higher conversion efficiency and broader bandwidth than a single crystal. At high irradiance, both multicrystal arrangements improve on the single crystal efficiency while maintaining broad bandwidth

  17. Broadband plasmon induced transparency in terahertz metamaterials

    KAUST Repository

    Zhu, Zhihua

    2013-04-25

    Plasmon induced transparency (PIT) could be realized in metamaterials via interference between different resonance modes. Within the sharp transparency window, the high dispersion of the medium may lead to remarkable slow light phenomena and an enhanced nonlinear effect. However, the transparency mode is normally localized in a narrow frequency band, which thus restricts many of its applications. Here we present the simulation, implementation, and measurement of a broadband PIT metamaterial functioning in the terahertz regime. By integrating four U-shape resonators around a central bar resonator, a broad transparency window across a frequency range greater than 0.40 THz is obtained, with a central resonance frequency located at 1.01 THz. Such PIT metamaterials are promising candidates for designing slow light devices, highly sensitive sensors, and nonlinear elements operating over a broad frequency range. © 2013 IOP Publishing Ltd.

    Although antinuclear campaigns seem to be effective, public communication and education efforts on low-level radioactive waste have mixed results. Attempts at public information programs on low-level radioactive waste still focus on influencing public opinion. A question then is: {open_quotes}Is it preferable to have a program focus on public education that will empower individuals to make informed decisions rather than trying to influence them in their decisions?{close_quotes} To address this question, a case study with both quantitative and qualitative data will be used. The Ohio Low-Level Radioactive Waste Education Program has a goal to provide people with information they want/need to make their own decisions. The program initiated its efforts by conducting a statewide survey to determine information needed by people and where they turned for that information. This presentation reports data from the survey and then explores the program development process in which programs were designed and presented using the information. Pre and post data from the programs reveal attitude and knowledge shifts.

  19. Broadband availability in metropolitan and non-metropolitan Pennsylvania

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available Over the past few years having a broadband connection has become essential for many Internet activities. As broadband increases in importance, it becomes imperative to assess how its use and availability may vary, especially in relation to issues such as geographic location. For rural areas in particular, the availability of broadband service is especially important. This research assesses broadband service availability in rural areas of Pennsylvania, USA. In particular, it examines the extent to which Digital Subscriber Line (DSL and broadband cable modem services are being deployed throughout rural Pennsylvania. It compares this deployment with the availability of such services in the state’s urban and metropolitan areas. The results of this research suggest that there is a “digital divide” in terms of broadband availability between rural and urban areas of Pennsylvania. However, this “divide” is perhaps not as wide as might be expected. Thus, as broadband is becoming increasingly available in rural areas of the U.S. and throughout much of the rest of the world, this research concludes that while research must remain vigilant in terms of assessing advanced telecommunications availability in rural areas, future research should also be sure to focus on how such technologies can be used to promote economic and social concerns, including in relation to building online networks and diminishing social and professional isolation in rural areas.

    Deployment of Broadband ISDN is being influenced by both a market pull and a technology push. New broadband service opportunities exist in the business and residential sectors of the market place. It is envisioned that some customers will need connections directly to broadband switches because of the high bandwidth needed for their applications. At the same time Metropolitan Area Network (MAN) systems will serve those customers with bandwidth requirements less than or equal to 150 Mbps. A given MAN will have a geographical domain to serve where it will carry out the switching tasks within this domain. While MANs couldbe designed using differentarchitecturalconcepts the setofservices expected tobeprovidedby MANs could be equivalent to thelist ofservices thatwillbe supported by the targetbroadband network. This paperpositions MANs as a major building block for Broadband networks. It also examines the evolution process ofMANs as a needed step to assure the successful deployment of these new broadband services. 2. BISDN - OVERVIEW Broadband ISDN (BISDN) is being driven into existence by both a market pull as well as a technology push. Opportunities for new valueadded services are the prime market pull for future broadband networks. These services opportunities extend beyond simple voice and low speed data applications and cover both the residential and the business sectors of the market. It is noted for instance that business customers have growing needs for sophisticated telecommunication vehicles to support their

    To evaluate the impact of a community-based peer support program for individuals and their family members following traumatic brain injury (TBI). Community-based sample of family members and individuals with traumatic brain injury. Twenty individuals who had participated in the peer support program (11 individuals with TBI and 9 family members). Quantitative and qualitative approaches were used: a retrospective structured interview assessing self-reported impacts of peer support on empowerment, quality of life, mood, skills and knowledge, and social supports; an in-depth qualitative interview with a subgroup of family members focused on the specific benefits/limitations of the peer support program. Participants in the peer support program reported positive impacts of peer support on increasing their knowledge of TBI, enhancing their overall quality of life, improving their general outlook, and enhancing their ability to cope with depression post TBI. The peer support program was reported to have had a minimal impact on enhancing social support from families, friends, and the community, with varying impacts noted on levels of happiness, coping with anger and anxiety, communication with professionals, and control over one's life. Qualitative analysis suggests the merits of this type of community-based support and areas of improvement for the peer support program itself. Preliminary data suggest that peer support is a promising approach to enhancing coping for both individuals and their family members after TBI.

  4. Speech recognition systems on the Cell Broadband Engine

    Liu, Y; Jones, H; Vaidya, S; Perrone, M; Tydlitat, B; Nanda, A

    2007-04-20

    In this paper we describe our design, implementation, and first results of a prototype connected-phoneme-based speech recognition system on the Cell Broadband Engine{trademark} (Cell/B.E.). Automatic speech recognition decodes speech samples into plain text (other representations are possible) and must process samples at real-time rates. Fortunately, the computational tasks involved in this pipeline are highly data-parallel and can receive significant hardware acceleration from vector-streaming architectures such as the Cell/B.E. Identifying and exploiting these parallelism opportunities is challenging, but also critical to improving system performance. We observed, from our initial performance timings, that a single Cell/B.E. processor can recognize speech from thousands of simultaneous voice channels in real time--a channel density that is orders-of-magnitude greater than the capacity of existing software speech recognizers based on CPUs (central processing units). This result emphasizes the potential for Cell/B.E.-based speech recognition and will likely lead to the future development of production speech systems using Cell/B.E. clusters.

    Full Text Available Mark Edgar Lemstra,1 Marla Rochelle Rogers2 1Department of Psychiatry, 2Department of Physical Medicine and Rehabilitation, College of Medicine, University of Saskatchewan, Saskatoon, SK, Canada Objectives: The risk for many chronic diseases increases with obesity. In addition to these, the risk for depression also increases. Exercise interventions for weight loss among those who are not overweight or obese have shown a moderate effect on depression, but few studies have looked at those with obesity. The objectives of this study were to determine 1 the prevalence of depressed mood in obese participants as determined by the Beck Depression Inventory II at baseline and follow-up; 2 the change in depressed mood between those who completed the program and those who did not; and 3 the differences between those whose depressed mood was alleviated after the program and those who continued to have depressed mood. Methods: Depressed mood scores were calculated at baseline and follow-up for those who completed the program and for those who quit. Among those who completed the program, chi-squares were used to determine the differences between those who no longer had depressed mood and those who still had depressed mood at the end of the program, and regression analysis was used to determine the independent risk factors for still having depressed mood at program completion. Results: Depressed mood prevalence decreased from 45.7% to 11.7% (P<0.000 from baseline to follow-up among those who completed the program and increased from 44.8% to 55.6% (P<0.000 among those who quit. After logistic regression, a score of <40 in general health increased the risk of still having depressed mood upon program completion (odds ratio [OR] 3.39; 95% CI 1.18–9.72; P=0.023. Conclusion: Treating depressed mood among obese adults through a community-based, weight-loss program based on evidence may be an adjunct to medical treatment. More research is needed.

    2016-02-01

    Child sexual abuse (CSA) prevention programs often include a focus on increased reporting of suspected abuse, in addition to other prevention components such as helping trainees recognize suspected abusive situations. This study aimed to determine whether the Stewards of Children prevention program is associated with increased CSA reporting. Analyses examined whether rates of CSA allegations increased over time in three counties in South Carolina (SC) targeted with program dissemination efforts and whether CSA reporting trends differed between the three targeted counties and three comparison counties that did not experience substantial program dissemination. CSA allegation data were obtained by county and year for predissemination and postdissemination periods from the SC Department of Social Services. Results indicated that, for the targeted counties but not the nontargeted counties, estimated allegation rates increased significantly over time, corresponding with the onset of significant program dissemination efforts. Results also indicated significant between-groups differences in allegation trends for targeted versus nontargeted counties. These findings suggest that the Stewards prevention intervention may be associated with increased CSA allegations. However, results require replication with randomization of counties. Moreover, whether increased reporting is associated with decreased CSA incidence remains unknown. © The Author(s) 2015.

    To design and implement a teaching skills curriculum that addressed the needs of an ophthalmology residency training program, to assess the effect of the curriculum, and to present important lessons learned. A teaching skills curriculum was designed for the Harvard Medical School (HMS) Residency Training Program in Ophthalmology. Results of a needs assessment survey were used to guide curriculum objectives. Overall, 3 teaching workshops were conducted between October 2012 and March 2013 that addressed areas of need, including procedural teaching. A postcurriculum survey was used to assess the effect of the curriculum. Massachusetts Eye and Ear Infirmary, a tertiary care institution in Boston, MA. Overall, 24 residents in the HMS Residency Training Program in Ophthalmology were included. The needs assessment survey demonstrated that although most residents anticipated that teaching would be important in their future career, only one-third had prior formal training in teaching. All residents reported they found the teaching workshops to be either very or extremely useful. All residents reported they would like further training in teaching, with most residents requesting additional training in best procedural teaching practices for future sessions. The pilot year of the resident-as-teacher curriculum for the HMS Residency Training Program in Ophthalmology demonstrated a need for this curriculum and was perceived as beneficial by the residents, who reported increased comfort in their teaching skills after attending the workshops.

    Purpose: The ASTRO document “Safety is no accident: A FRAMEWORK FOR QUALITY RADIATION ONCOLOGY AND CARE” recommends external reviews of specialized modalities. The purpose of this presentation is to describe the implementation of such a program for Stereotactic Radiosurgery (SRS) and Stereotactic Body radiation Therapy (SBRT). Methods: The margin of error for SRS and SBRT delivery is significantly smaller than that of conventional radiotherapy and therefore requires special attention and diligence. The Novalis Certified program was created to fill an unmet need for specialized SRS / SBRT credentialing. A standards document was drafted by a panel of experts from several disciplines, including medical physics, radiation oncology and neurosurgery. The document, based on national and international standards, covers requirements in program structure, personnel, training, clinical application, technology, quality management, and patient and equipment QA. The credentialing process was modeled after existing certification programs and includes an institution-generated self-study, extensive document review and an onsite audit. Reviewers generate a descriptive report, which is reviewed by a multidisciplinary expert panel. Outcomes of the review may include mandatory requirements and optional recommendations. Results: 15 institutions have received Novalis Certification, including 3 in the US, 7 in Europe, 4 in Australia and 1 in Asia. 87 other centers are at various stages of the process. Nine reviews have resulted in mandatory requirements, however all of these were addressed within three months of the audit report. All reviews have produced specific recommendations ranging from programmatic to technical in nature. Institutions felt that the credentialing process addressed a critical need and was highly valuable to the institution. Conclusion: Novalis Certification is a unique peer review program assessing safety and quality in SRS and SBRT, while recognizing

    As nurse home visiting to prevent child maltreatment grows in popularity with both program administrators and legislators, it is important to understand engagement in such programs in order to improve their community-wide effects. This report examines family demographic and infant health risk factors that predict engagement and follow-through in a universal home-based maltreatment prevention program for new mothers in Durham County, North Carolina. Trained staff members attempted to schedule home visits for all new mothers during the birthing hospital stay, and then nurses completed scheduled visits three to five weeks later. Medical record data was used to identify family demographic and infant health risk factors for maltreatment. These variables were used to predict program engagement (scheduling a visit) and follow-through (completing a scheduled visit). Program staff members were successful in scheduling 78% of eligible families for a visit and completing 85% of scheduled visits. Overall, 66% of eligible families completed at least one visit. Structural equation modeling (SEM) analyses indicated that high demographic risk and low infant health risk were predictive of scheduling a visit. Both low demographic and infant health risk were predictive of visit completion. Findings suggest that while higher demographic risk increases families' initial engagement, it might also inhibit their follow-through. Additionally, parents of medically at-risk infants may be particularly difficult to engage in universal home visiting interventions. Implications for recruitment strategies of home visiting programs are discussed. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The authors have collaborated for over three years in developing an advanced educational program to cultivate leading engineers who can productively interact with other stakeholders. The program is organized under a partnership between the Nuclear Engineering Department of University of California, Berkeley (UCBNE) and the Global COE Program 'Nuclear Education and Research Initiative' (GoNERI) of the University of Tokyo, and is funded by MEXT (Ministry of Education, Culture, Sports, Science and Technology), Japan. We conducted two 'summer schools' in 2009 and 2010 as trial cases of the educational program. This year, in response to the Fukushima Daiichi nuclear accident, we decided to make our third summer school a venue for preliminary, yet multi-dimensional learning from that event. This school was held in Berkeley, CA, in the first week of August, with 12 lecturers and 18 students from various fields and countries. In this paper, we will explain the concept, aim, and design of our program; do a preliminary assessment of its effectiveness; introduce a couple of intriguing discussions held by participants; and discuss the program's implications for the post-Fukushima nuclear context.

    Greenfield, Emily A

    2014-03-01

    This study aimed to develop theory on how Naturally Occurring Retirement Communities (NORC) Supportive Service Programs potentially transform social relationships within communities to promote aging in place. Data were analyzed from semi-structured in-depth interviews with 10 lead agencies representing 15 NORC programs in New Jersey. Results indicated that professionals seek to infuse capital within three domains of relationships: lead agency staff's relationships with older adults, formal service providers' relationships with each other, and older adults' relationships with each other. This social capital potentially enhances the amount of community-based services and supports within a residential area, as well as their accessibility, appropriateness, responsiveness, and coherence.

    2001-05-31

    Electric motor systems are widely used in China to power fans, pumps, blowers, air compressors, refrigeration compressors, conveyers, machinery, and many other types of equipment. Overall, electric motor systems consume more than 600 billion kWh annually, accounting for more than 50 percent of China's electricity use. There are large opportunities to improve the efficiency of motor systems. Electric motors in China are approximately 2-4 percent less efficient on average than motors in the U.S. and Canada. Fans and pumps in China are approximately 3-5 percent less efficient than in developed countries. Even more importantly, motors, fans, pumps, air compressors and other motor-driven equipment are frequently applied with little attention to system efficiency. More optimized design, including appropriate sizing and use of speed control strategies, can reduce energy use by 20 percent or more in many applications. Unfortunately, few Chinese enterprises use or even know about these energy-saving practices. Opportunities for motor system improvements are probably greater in China than in the U.S. In order to begin capturing these savings, China is establishing a China Motor Systems Energy Conservation Program. Elements of this program include work to develop minimum efficiency standards for motors, a voluntary ''green motor'' labeling program for high-efficiency motors, efforts to develop and promote motor system management guidelines, and a training, technical assistance and financing program to promote optimization of key motor systems.

    The surface of Mars has been extensively investigated and huge amount of data have been acquired such as high Res images. On the other hand interior of the Mars has been only weakly constrained by the mean density, the moment of inertia and gravity data. The size of core is poorly constrained and negatively correlated with the core density. High dissipation state is reported for the mantle by tidal interaction (Bills et al 2006), which is against a conventional view of small,cool planet. To clarify these points seismic observation on Mars is deadly needed. Japan Mars exploration project(MELOS) is now under discussion and it includes seismic measurements for determination the interior structure of Mars such as the core size, its state and attenuation in the mantle. Our plan is to install broadband high sensitivity seismometers,which are intended to detect continuous excitation of free oscillation by atmospheric turbulence. In this presentation we would like to show a basic design of broadband high sensitivity seismometer as well as environment protection designs. The basic parts are composed of a long period pendulum, laser interferometry and its control feedback electricity. As for the environment protection design,the following factors are important. 1. Surface condition. Martian surface is composed of stones gravels and sand. Drift is expected to occur due to the sudden change in ground slope. We need a device for self adjustment to keep the horizontal. 2. Temperature. Surface temperature at Martian equator is expected to vary between 190 to 300K. We have to consider changes in spring tension, thermal expansion of components and changes in circuit constants. 3. Surface wind. Inhomogeneously heated surface and topographic effect generate wind over 20m per second. We have to consider to lessen the effect of seismometer,even if we install the seismometer on the ground. 4. Radiation. Radiation that rains down on Mars is stronger because of thin atmosphere. Radiation

    This article describes the design, implementation, and evaluative findings of the HEROES (Healthy, Energetic, Ready, Outstanding, Enthusiastic, Schools) Initiative, a school-based multilevel childhood obesity prevention intervention. Based on the Centers for Disease Control and Prevention's recommended coordinated school health approach, the HEROES Initiative works to alleviate the burden of childhood obesity in Southern Indiana, Northwestern Kentucky, and Southeastern Illinois in the United States. Process evaluation was conducted with the 17 participating schools in spring 2012 based on interviews with school personnel and observation of the school environment. Findings showed that despite some variability, schools were generally able to implement the intervention with fidelity. School-level outcome evaluation was also based on observation of the school environment, and revealed that schools had implemented a number of new practices to encourage physical activity and healthy eating. Assessment of student-level outcomes was based on professionally collected physiological measurements and self-reported behavioral data collected over an 18-month period of time, last collected in spring 2012. Findings demonstrated that the HEROES Initiative has been successful in reducing the percentage of overweight children in participating schools and healthfully modifying their dietary, physical activity, and sedentary behaviors. Strategies that have facilitated success and challenges related to the intervention are discussed.

    A broadband cable system represents a significant resource for data transmission within a facility. Duplication of a broadband network to provide services of varying sensitivity levels within the same area is wasteful of capital resources. The sharing of a network by different data services is financially attractive providing that sensitive data are inaccessible from nonsensitive ports. The use of equipment from two manufacturers introduces a deliberate incompatibility for the purpose of data isolation. This report presents test results obtained by this technique.

    For four years the National Science Foundation (NSF)-sponsored TeXas Earth and Space Science (TXESS) Revolution professional development program has helped teachers build a solid foundation in the geosciences through guided inquiry activities and lectures delivered by science experts. The professional development program comprises eight professional development academies and two summer institutes. Climate literacy has been a cross-cutting theme throughout the series of academies and institutes. Although we present a special emphasis on climate literacy in the 7th academy on Climate Change, the 8th academy on Humans at the Helm and the 2nd summer institute module on climate mitigation technology, activities related to climate literacy are woven into each academy. Examples of climate as a cross-cutting theme include a module on water and drought, including research on climate change through the analysis of deep-sea cores, and the effects on the Mayan population. Our distinguished lecturers bring in climate literacy as part of their presentations and programs: our Poking Holes into the Planet and Team Science professional development academy included two distinguished lecturers who brought current research results and educational materials from the ANDRILL (Antarctic Geological Drilling) program and the Integrated Ocean Drilling Program. Our Earth as a Habitable Planet professional development academy featured an activity on corals that used data to explore how higher than normal sea surface temperatures contribute to coral bleaching events. TXESS Revolution also works with our teachers to link them with other opportunities aligned with our professional development goals. With our assistance, one of our TXESS Revolution teachers sailed as part of the science team on Integrated Ocean Drilling Program expedition 317 to investigate sea level fluctuations in the Canterbury Basin offshore New Zealand, creating various resources (e.g., podcasts, blogs) to multiply the

    The Hunger Prevention and Nutrition Assistance Program (HPNAP) is a New York State Department of Health program. The HPNAP improves nutritional quality of food available at food banks, food pantries, soup kitchens, and emergency shelters through contractual relationships to fund the purchase, delivery, storage, and service of nutritious food. To determine whether a one-time fiscal stimulus of the Locally Grown Produce Initiative to HPNAP contractors in 2012-2013 would result in a short-term sustainable increase in the proportion of dollars spent on New York State Grown (NYSG) produce. Quasi-experimental, nonequivalent control group design. We analyzed New York State Department of Health administrative data regarding expenditures on all produce and NYSG produce by HPNAP contractors. New York State. The proportion of dollars spent on NYSG produce during 2011-2012 (preintervention) and 2013-2014 (postintervention) was compared between HPNAP food bank contractors (recipients of stimulus money, n = 8) and non-food bank contractors (nonrecipients, n = 34) using nonparametric methods. The HPNAP Locally Grown Produce Initiative was associated with an increased proportion of NYSG produce spending by food bank contractors that received a fiscal stimulus 1 year later. Upstate food banks had the largest increase (median 31.6%) among all HPNAP contractors. The results of this study revealed that the Locally Grown Produce Initiative fiscal stimulus had a positive, year-long and statewide effect on the proportion of expenditure on NYSG produce by food banks. We hope that the initial success seen in New York State may encourage other states to adopt similar initiatives in future.

    We assessed the use of a microswitch-based program for promoting ambulation responses by two children with multiple disabilities. The goals of the study were to: (a) evaluate the importance of the contingency between the target behavior (forward step) and the programmed consequence (preferred stimuli), (b) measure effects of the intervention on indices of happiness, and (c) assess the social validation of the procedure using 20 physiotherapists as external raters. The intervention involved the automatic delivery of preferred stimuli contingent on forward steps. Results showed that both participants improved their performance (forward steps and indices of happiness) during contingent reinforcement phases compared to baseline and noncontingent reinforcement phases. Moreover, physiotherapists rated the intervention as socially valid. © 2017 Society for the Experimental Analysis of Behavior.

  18. Developing a Broadband Adoption Model in the UK Context

    Dwivedi, Yogesh K.; Mustafee, Navonil; Williams, Michael D.; Lal, Banita

    This research examines the factors affecting the consumer adoption of broadband in the United Kingdom. A conceptual model of broadband adoption was developed by selecting and justifying a number of relevant constructs from the technology adoption literature. The model was then empirically tested by employing survey data that was randomly collected from 358 UK broadband consumers. The findings suggest that, with the exception of one construct that was included in the conceptual model (namely, knowledge), all of the con structs significantly influence consumers when adopting broadband in a UK household. The significant constructs include relative advantage, utilitarian outcomes, hedonic outcomes, primary influence, facilitating conditions resources, and self-efficacy. Furthermore, when considering the behavioral intention and facilitating conditions resources constructs together, they significantly explain UK broad band adoption behavior. The theoretical contri bution of this research is that it determines and integrates the appropriate constructs from the technology adoption literature in order to enhance the knowledge of technology adoption from the consumer's perspective. This research has implications for policy makers and broadband providers since the results of this study can be exploited by the aforementioned stakeholders in order to encourage and promote the adoption and usage of broadband among the general population.

  19. Broadband properties of active galactic nuclei

    Science.gov (United States)

    Edelson, Richard Allen

    The broadband radio-infrared-optical-ultraviolet properties of active galactic nuclei are used to investigate the nature of the central engine and the surrounding environment. Optically selected quasars and Seyfert 1 galaxies tend to have relatively flat infrared spectra and low reddenings, while most Seyfert 2 galaxies and other dusty objects have steep infrared spectra and larger reddenings. The infrared spectra of most luminous radio-quiet active galaxies turn over near approx. 80 micron. It appears that the infrared spectra of most quasars and luminous Seyfert 1 galaxies are dominated by unreprocessed radiation from a synchrotron self-absorbed source of order a light day across, about the size of the hypothesized accretion disk. Seyfert 2 galaxies and other reddened objects have infrared spectra which appear to be dominated by thermal emission from warm dust, probably in the disk of the underlying galaxy. A broad emission feature, centered near 5 micron, is present in many luminous quasars and Seyfert 1 galaxies. Highly polarized objects (blazars) can be strongly variable at far infrared wavelengths over time scales of months. Seyfert galaxies tend to have steep radio spectra.

    2015-02-01

    Full Text Available The chemical environment of cells is an extremely complex and multifaceted system that includes many types of proteins, lipids, nucleic acids and various other components. With the final aim of studying these components in detail, we have developed multiband plasmonic antennas, which are suitable for highly sensitive surface enhanced Raman spectroscopy (SERS and are activated by a wide range of excitation wavelengths. The three-dimensional hollow nanoantennas were produced on an optical resist by a secondary electron lithography approach, generated by fast ion-beam milling on the polymer and then covered with silver in order to obtain plasmonic functionalities. The optical properties of these structures have been studied through finite element analysis simulations that demonstrated the presence of broadband absorption and multiband enhancement due to the unusual geometry of the antennas. The enhancement was confirmed by SERS measurements, which showed a large enhancement of the vibrational features both in the case of resonant excitation and out-of-resonance excitation. Such characteristics indicate that these structures are potential candidates for plasmonic enhancers in multifunctional opto-electronic biosensors.

    The development of a family of silicon based integrated vibration sensors capable of sensing mechanical resonances over a broad range of frequencies with minimal signal processing requirements is presented. Two basic general embodiments of the concept were designed and fabricated. The first design was structured around an array of cantilever beams and fabricated using the ARPA sponsored multi-user MEMS processing system (MUMPS) process at the Microelectronics Center of North Carolina (MCNC). As part of the design process for this first sensor, a comprehensive finite elements analysis of the resonant modes and stress distribution was performed using PATRAN. The dependence of strain distribution and resonant frequency response as a function of Young's modulus in the Poly-Si structural material was studied. Analytical models were also studied. In-house experimental characterization using optical interferometry techniques were performed under controlled low pressure conditions. A second design, intended to operate in a non-resonant mode and capable of broadband frequency response, was proposed and developed around the concept of a cantilever beam integrated with a feedback control loop to produce a null mode vibration sensor. A proprietary process was used to integrat a metal-oxide semiconductor (MOS) sensing device, with actuators and a cantilever beam, as part of a compatible process. Both devices, once incorporated as part of multifunction data acquisition and telemetry systems will constitute a useful system for NASA launch vibration monitoring operations. Satellite and other space structures can benefit from the sensor for mechanical condition monitoring functions.

  2. Broadband Vibration Attenuation Using Hybrid Periodic Rods

    Directory of Open Access Journals (Sweden)

    S. Asiri

    2008-12-01

    Full Text Available This paper presents both theoretically and experimentally a new kind of a broadband vibration isolator. It is a table-like system formed by four parallel hybrid periodic rods connected between two plates. The rods consist of an assembly of periodic cells, each cell being composed of a short rod and piezoelectric inserts. By actively controlling the piezoelectric elements, it is shown that the periodic rods can efficiently attenuate the propagation of vibration from the upper plate to the lower one within critical frequency bands and consequently minimize the effects of transmission of undesirable vibration and sound radiation. In such a system, longitudinal waves can propagate from the vibration source in the upper plate to the lower one along the rods only within specific frequency bands called the "Pass Bands" and wave propagation is efficiently attenuated within other frequency bands called the "Stop Bands". The spectral width of these bands can be tuned according to the nature of the external excitation. The theory governing the operation of this class of vibration isolator is presented and their tunable filtering characteristics are demonstrated experimentally as functions of their design parameters. This concept can be employed in many applications to control the wave propagation and the force transmission of longitudinal vibrations both in the spectral and spatial domains in an attempt to stop/attenuate the propagation of undesirable disturbances.

  3. Investigating broadband acoustic adsorption using rapid manufacturing

    Science.gov (United States)

    Godbold, O.

    The reduction of nuisance noise and the removal of unwanted sound modes within a room or component enclosure-area can be accomplished through the use of acoustic absorbers. Sound absorption can be achieved through conversion of the kinetic energy associated with pressure waves, into heat energy via viscous dissipation. This occurs within open porous materials, or by utilising resonant effects produced using simple cavity and orifice configurations. The manufacture of traditional porous and resonant absorbers is commonly realised using basic manufacturing techniques. These techniques restrict the geometry of a given resonant construction, and limit the configuration of porous absorbers. The aim of this work is to exploit new and emerging capabilities of Rapid Manufacturing (RM) to produce components with geometrical freedom, and apply it to the development of broadband acoustic absorption. New and novel absorber geometric configurations are identified and their absorption performance is determined. The capabilities and limitations of RM processes in reproducing these configurations are demonstrated. The geometric configuration of RM resonant absorbers is investigated. Cavity modifications aimed at damping the resonant effect by restricting the motion of cavity air, and adding increased viscous resistance are explored. Modifications relating to cavity shape, the addition of internal perforations and increased cavity surface area have all been shown to add acoustic resistance, thereby increasing the bandwidth of absorption. Decreasing the hydraulic radius of the cavity cross section and reducing internal feature dimensions provide improved resistance over conventional configurations..

    The reversible transfer of quantum states of light into and out of matter constitutes an important building block for future applications of quantum communication: it will allow the synchronization of quantum information, and the construction of quantum repeaters and quantum networks. Much effort has been devoted to the development of such quantum memories, the key property of which is the preservation of entanglement during storage. Here we report the reversible transfer of photon-photon entanglement into entanglement between a photon and a collective atomic excitation in a solid-state device. Towards this end, we employ a thulium-doped lithium niobate waveguide in conjunction with a photon-echo quantum memory protocol, and increase the spectral acceptance from the current maximum of 100 megahertz to 5 gigahertz. We assess the entanglement-preserving nature of our storage device through Bell inequality violations and by comparing the amount of entanglement contained in the detected photon pairs before and after the reversible transfer. These measurements show, within statistical error, a perfect mapping process. Our broadband quantum memory complements the family of robust, integrated lithium niobate devices. It simplifies frequency-matching of light with matter interfaces in advanced applications of quantum communication, bringing fully quantum-enabled networks a step closer.

    Broadband Laser Ranging (BLR) is a new diagnostic being developed to precisely measure the position vs. time of surfaces, shock break out, particle clouds, jets, and debris moving at kilometers per second speeds. The instrument uses interferometry to encode distance into a modulation in the spectrum of pulses from a mode-locked fiber laser and uses a dispersive Fourier transformation to map the spectral modulation into time. Range information is thereby recorded on a fast oscilloscope at the repetition rate of the laser, approximately every 50 ns. Current R&D is focused on developing a compact 8-channel system utilizing one laser and one high-speed oscilloscope. This talk will emphasize the hardware being developed for applications at the Contained Firing Facility at LLNL, but has a common architecture being developed in collaboration with NSTec and LANL for applications at multiple other facilities.

  6. A Broadband Ultrathin Nonlinear Switching Metamaterial

    2017-05-01

    Full Text Available In this paper, an ultrathin planar nonlinear metamaterial slab is designed and simulated. Nonlinearity is provided through placing diodes in each metamaterial unit cell. The diodes are auto-biased and activated by an incident wave. The proposed structure represents a broadband switching property between two transmission and reflection states depending on the intensity of the incident wave. High permittivity values are presented creating a near zero effective impedance at low power states, around the second resonant mode of the structure unit cell; as the result, the incident wave is reflected. Increasing the incident power to the level which can activate the loaded diodes in the structure results in elimination of the resonance and consequently a drop in the permittivity values near the permeability one as well as a switch to the transmission state. A full wave as well as a nonlinear simulations are performed. An optimization method based on weed colonization is applied to the unit cell of the metamaterial slab to achieve the maximum switching bandwidth. The structure represents a 24% switching bandwidth of a 10 dB reduction in the reflection coefficient.

    The goals of this study were to develop and evaluate a joint theoretical/practical training course for radiology residents and technicians and to start a collaborative practice agreement enabling radiology technicians to perform PICC placement under the responsibility of an interventional radiologist. A joint training session based on literature evidences and international recommendations was designed. Participants were assessed before and after training, and were also asked to evaluate the program one month after completion of the training course. Practical post-training mentoring guidelines were laid down for radiologists supervising technicians. From January to April 2014, 6 radiology residents and 12 radiology technicians from the two interventional radiology departments of the University hospitals in Marseille took part in the training program. For both residents and technicians, significant improvement was observed between pretraining and post-training assessment. The majority of participants were satisfied with the program. Our experience suggests that combined theoretical and practical training in PICC placement allows improving technical skill and yields high degrees of satisfaction for both radiology residents and technicians. A collaborative practice agreement is now formally established to enable radiologists to delegate PICC placement procedures to radiology technicians.

    Carrying a spirit of a long history of cooperation in physics education and research between Fisk University and Vanderbilt University, the Nuclear Research Program in the Department of Physics at Fisk University was proposed in 1996 in cooperation with the Nuclear Physics Group at Vanderbilt University. An initial NRP program was commissioned in 1997 with the financial support from DOE. The program offers a great opportunity for students and faculty at Fisk University to directly access experimental nuclear data and analyzing facilities within the Nuclear Physics Group at Vanderbilt University for a quick start. During the program Fisk Faculty and students (along with the colleagues at Vanderbilt University) have achieved progress in a few areas. We have (a) established an in-house nuclear data processing and analysis program at Fisk University, (b) conducted hands-on nuclear physics experiments for a Fisk undergraduate student at Vanderbilt University, (c) participated in the UNIRIB research with radioactive ion beam and Recoil Mass Spectrometer at Oak Ridge National Laboratory, and (d) studied {sup 252}Cf spontaneous fission and in-beam nuclear reactions for exotic nuclei. Additionally, this work has produced publication in conference proceedings as well as referred journals. [2-7].

    To evaluate the Turkey's nationwide HPV DNA screening program on the basis of first 1 million screened women. Women over age 30 were invited for population based screening via HPV DNA and conventional cytology. Samples were collected by family physicians and the evaluations and reports had been performed in the National Central HPV laboratories. The acceptance rate for HPV based cervical cancer screening after first invitation was nearly 36.5%. Since HPV DNA tests have been implemented, cervical cancer screening rates have shown 4-5-fold increase in primary level. Through the evaluation of all, HPV positivity was seen in 3.5%. The commonest HPV genotypes were 16, followed by 51, 31, 52 and 18. Among the 37.515 HPV positive cases, cytological abnormality rate was 19.1%. Among HPV positive cases, 16.962 cases had HPV 16 or 18 or other oncogenic HPV types with abnormal cytology (>ASC-US). These patients were referred to colposcopy. The colposcopy referral rate was 1.6%. Among these, final clinico-pathological data of 3.499 patients were normal in 1.985 patients, CIN1 in 708, CIN2 in 285, CIN3 in 436 and cancer in 85 patients and only pap-smear program could miss 45.9% of ≥CIN3 cases. The results of 1 million women including the evaluation of 13 HPV genotypes with respect to prevalence, geographic distribution and abnormal cytology results shows that HPV DNA can be used in primary level settings to have a high coverage rated screening program and is very effective compared to conventional pap-smear. © 2017 The Authors International Journal of Cancer published by John Wiley & Sons Ltd on behalf of UICC.

    The Radiotherapy Department at Heidelberg Repatriation Hospital has purchased the first Digital Portal Imaging System (DPIS) in Australia. The DPIS has a demountable armature attached to a Philips SL15 6MV X-ray therapy unit. The SRI-100 captures images which can then be printed, stored or processed for image enhancement. The component sections of the DPIS are image detection, conversion, processing, control and display. All sections are made up from original equipment manufacturer modules that should provide for ease of access to spare parts and technical support. Computer control is provided from a Compaq 386-SX PC using DOS version 3.3 and a GEM desktop environment. The imaging software is user friendly and provides the operator with a comparatively easy environment in which to write dedicated image processing procedures as the need arises. The standard software provides a large number of image processing routines including filters, statistical functions, grey-scale manipulation and image housekeeping. A daily quality assurance (QA) program has been implemented using system software to check camera noise and image saturation, with a monthly imaging QA program using the RMI Portal Film Phantom. The systems strengths and weaknesses are discussed along with suggested hardware and software improvements and upgrades. 8 refs., 2 tabs., 7 figs

    Full Text Available Rural populations experience higher rates of illness, less access to health care resources, and lower rates of health insurance coverage than do urban populations. A need exists to identify and address the health care needs of rural communities and other isolated populations and to contextualize the findings in the larger rural health environment. Critical ethnography combined with community-based action research is a constructive approach for improving the health status of rural elders as well as other members of isolated communities. Detailed guidelines on how to initiate an ethnographic community-based action study, as shown through a study that explores the definitions of health, health care perceptions, and health care issues for rural elders in the southwestern United States, highlight the value of this type of research for the study of the health care issues of rural populations.

    The current NWS ground based network is not sufficient to capture the dynamic or thermodynamic structure leading to the initiation and organization of air mass moist convective events. Under this investigation we intend to use boundary layer mesoscale models (McNider and Pielke, 1981) to examine the dynamic triggering of convection due to topography and surface thermal contrasts. VAS and MAN's estimates of moisture will be coupled with the dynamic solution to provide an estimate of the total convective potential. Visible GOES images will be used to specify incoming insolation which may lead to surface thermal contrasts and JR skin temperatures will be used to estimate surface moisture (via the surface thermal inertia) (Weizel and Chang, 1988) which can also induce surface thermal contrasts. We will use the SPACE-COHMEX data base to evaluate the ability of the joint mesoscale model satellite products to show skill in predicting the development of air mass convection. We will develop images of model vertical velocity and satellite thermodynamic measures to derive images of predicted convective potential. We will then after suitable geographic registration carry out a pixel by pixel correlation between the model/satellite convective potential and the 'truth' which are the visible images. During the first half of the first year of this investigation we have concentrated on two aspects of the project. The first has been in generating vertical velocity fields from the model for COHMEX case days. We have taken June 19 as the first case and have run the mesoscale model at several different grid resolutions. We are currently developing the composite model/satellite convective image. The second aspect has been the attempted calibration of the surface energy budget to provide the proper horizontal thermal contrasts for convective initiation. We have made extensive progress on this aspect using the FIFE data as a test data set. The calibration technique looks very promising.

    EPRI sstudies have shown that nuclear plant capital costs will have to decrease by about 35% to 40% to be competitive with fossil-generated electricity in the Unite States. Also, the ''first concrete'' to fuel load construction schedule will have to be decreased to less than 40 months. Therefore, the U. S. Department of Energy (DOE) initiate the Nuclear Energy Research Initiative (NERI) and ABB CENP proposed a cooperative program with Sandia National Laboratory (SNL) and Duke Engineering and Services (DE and S) to begin an innovative research effort to drastically cut the cost of new nuclear power plant construction for the U. S. de-regulated market place. This program was approved by the DOE through three separate but coordinated ''cooperative agreements.'' They are the ''Risk-Informed Assessment of Regulatory and Design Requirements for Future Nuclear Power Plants'' (Risk-Informed NPP), the ''Smart Nuclear Power Plant Program'' (Smart-NPP), and ''Design, Procure, Construct, Install and Test'' (DPCIT) Program. DOE funded the three cooperative agreements at a level of $2.6 million for the first year of the program. Funding for the complete program is durrently at a level $6.9 million, however, ABB CENP and all partners anticipate that the scope of the NERI program will be increased as a result of the overall importance of NERI to the U. S. Government. The Risk-Informed NPP program, which is aimed at revising costly regularory and design requirements without reducing overall plant safety, has two basic tasks: ''development of Risk-Informed Methods'' and ''strengthening the Reliability Database.'' The overall objective of the first task is to develop a scientific, risk-informed approach for identifying and simplifying deterministic industry standards, regulatory requirements, and safety systems that do not significantly contribute to nuclear power plant reliability and safety. The second basic task is to develop a means for strengthening the reliability database

    We present our broadband (2–250 keV) time-averaged spectral analysis of 388 bursts from SGR J1550−5418, SGR 1900+14, and SGR 1806−20 detected with the Rossi X-ray Timing Explorer ( RXTE ) here and as a database in a companion web-catalog. We find that two blackbody functions (BB+BB), the sum of two modified blackbody functions (LB+LB), the sum of a blackbody function and a power-law function (BB+PO), and a power law with a high-energy exponential cutoff (COMPT) all provide acceptable fits at similar levels. We performed numerical simulations to constrain the best fitting model for each burst spectrum and found that 67.6% of burst spectra with well-constrained parameters are better described by the Comptonized model. We also found that 64.7% of these burst spectra are better described with the LB+LB model, which is employed in the spectral analysis of a soft gamma repeater (SGR) for the first time here, than with the BB+BB and BB+PO models. We found a significant positive lower bound trend on photon index, suggesting a decreasing upper bound on hardness, with respect to total flux and fluence. We compare this result with bursts observed from SGR and AXP (anomalous X-ray pulsar) sources and suggest that the relationship is a distinctive characteristic between the two. We confirm a significant anticorrelation between burst emission area and blackbody temperature, and find that it varies between the hot and cool blackbody temperatures differently than previously discussed. We expand on the interpretation of our results in the framework of a strongly magnetized neutron star.

    2017-06-01

    With the advancement of chirped-pulse techniques, broadband rotational spectra with a few tens to several hundred GHz of spectral coverage are now routinely recorded. When studying multi-component mixtures that might result, for example, with the use of an electrical discharge, lines of new chemical species are often obscured by those of known compounds, and analysis can be laborious. To address this issue, we have developed SPECdata, an open source, interactive tool which is designed to simplify and greatly accelerate the spectral analysis and discovery. Our software tool combines both automated and manual components that free the user from computation, while giving him/her considerable flexibility to assign, manipulate, interpret and export their analysis. The automated - and key - component of the new software is a database query system that rapidly assigns transitions of known species in an experimental spectrum. For each experiment, the software identifies spectral features, and subsequently assigns them to known molecules within an in-house database (Pickett .cat files, list of frequencies...), or those catalogued in Splatalogue (using automatic on-line queries). With suggested assignments, the control is then handed over to the user who can choose to accept, decline or add additional species. Data visualization, statistical information, and interactive widgets assist the user in making decisions about their data. SPECdata has several other useful features intended to improve the user experience. Exporting a full report of the analysis, or a peak file in which assigned lines are removed are among several options. A user may also save their progress to continue at another time. Additional features of SPECdata help the user to maintain and expand their database for future use. A user-friendly interface allows one to search, upload, edit or update catalog or experiment entries.

    We present a multi-wavelength study of four high redshift blazars, S5 0014+81 ( z = 3.37), CGRaBS J0225+1846 ( z = 2.69), BZQ J1430+4205 ( z = 4.72), and 3FGL J1656.2−3303 ( z = 2.40) using quasi-simultaneous data from the Swift , Nuclear Spectroscopic Telescope Array ( NuSTAR ) and the Fermi -Large Area Telescope (LAT) and also archival XMM-Newton observations. Other than 3FGL J1656.2−3303, none of the sources were known as γ -ray emitters, and our analysis of ∼7.5 yr of LAT data reveals the first time detection of statistically significant γ -ray emission from CGRaBS J0225+1846. We generate the broadband spectral energy distributions (SED) of all the objects, centering at the epoch of NuSTAR observations and reproduce them using a one-zone leptonic emission model. The optical−UV emission in all the objects can be explained by radiation from the accretion disk, whereas the X-ray to γ -ray windows of the SEDs are found to be dominated by inverse Compton scattering off the broad line region photons. All of them host black holes that are billions of solar masses. Comparing the accretion disk luminosity and the jet power of these sources with a large sample of blazars, we find them to occupy a high disk luminosity–jet power regime. We also investigate the X-ray spectral properties of the sources in detail with a major focus on studying the causes of soft X-ray deficit, a feature generally seen in high redshift radio-loud quasars. We summarize that this feature could be explained based on the intrinsic curvature in the jet emission rather than being due to the external effects predicted in earlier studies, such as host galaxy and/or warm absorption.

  6. Computing broadband accelerograms using kinematic rupture modeling

    Ruiz Paredes, J.A.

    2007-05-01

    In order to make the broadband kinematic rupture modeling more realistic with respect to dynamic modeling, physical constraints are added to the rupture parameters. To improve the slip velocity function (SVF) modeling, an evolution of the k -2 source model is proposed, which consists to decompose the slip as a sum of sub-events by band of k. This model yields to SVF close to the solution proposed by Kostrov for a crack, while preserving the spectral characteristics of the radiated wave field, i.e. a w 2 model with spectral amplitudes at high frequency scaled to the coefficient of directivity C d . To better control the directivity effects, a composite source description is combined with a scaling law defining the extent of the nucleation area for each sub-event. The resulting model allows to reduce the apparent coefficient of directivity to a fraction of C d , as well as to reproduce the standard deviation of the new empirical attenuation relationships proposed for Japan. To make source models more realistic, a variable rupture velocity in agreement with the physics of the rupture must be considered. The followed approach that is based on an analytical relation between the fracture energy, the slip and the rupture velocity, leads to higher values of the peak ground acceleration in the vicinity of the fault. Finally, to better account for the interaction of the wave field with the geological medium, a semi-empirical methodology is developed combining a composite source model with empirical Green functions, and is applied to the Yamaguchi, M w 5.9 earthquake. The modeled synthetics reproduce satisfactorily well the observed main characteristics of ground motions. (author)

    The present paper takes a translational approach in applying the themes of the current special section to prevention and intervention science in Latino families. The paper reviews the current literature on cultural processes in prevention and intervention research with Latino families. Overall, many prevention and intervention programs have either been developed specifically for Latino families or have been modified for Latino families with great attention paid to the socio-cultural needs of these families. Nevertheless, few studies have tested the role of cultural values or acculturation processes on outcomes. We make recommendations based on findings within basic science and in particular this special section on the incorporation of these values and processes into prevention and intervention science with Latino families. © 2015 Family Process Institute.

    The authors report on the development of high power, high energy microwave modules. The HDL-Varian high-power magnetron program is unique in the HPM field in that established crossed-field tube technologies are being exploited in order to circumvent many of the difficulties inherent in other HPM sources. Instead of using explosive field emission cathodes, short pulse lengths, and extremely high voltages, the authors are operating with secondary emission cathodes, carefully conditioned high vacuum surfaces, and more moderate dc and rf fields. As a result, typical crossed-field tube properties are expected including long pulse lengths, high efficiency, relatively low operating voltages and magnetic fields, and high phase stability and control using well isolated low-power rf drivers. High efficiency and moderate voltages allow for the use of proven high repetition rate modulator technology. Preliminary results from an 18-vane rising sun magnetron are presented

    Effective nursing leadership is necessary for the delivery of safe, high quality healthcare. Yet experience and research tells us that nursing leaders are commonly unprepared for their roles. Take The Lead (TTL), a large-scale, multifaceted professional development program was initiated in New South Wales, Australia, to strengthen the capacity of Nursing/Midwifery Unit Managers (N/MUMs). The aim of this study was to examine the effects of TTL on job performance, nursing leadership and patient experience. Nursing/Midwifery Unit Managers (n = 30) and managers of N/MUMs (n = 30) who had completed the TTL program were interviewed between August and December 2010. The semi-structured interviews included a combination of open-ended questions and questions that required respondents to rate statements using a Likert scale. Data from the open-ended questions were thematically analysed to identify and categorise key concepts. The responses to the Likert items were analysed via descriptive statistics. Nursing/Midwifery Unit Managers' participation in TTL engendered improvements in job performance and leadership skills, as well as some improvement in patients' experiences of care. The program facilitated role clarification and helped foster peer-support and learning networks, which were perceived to provide ongoing professional and personal benefits to participants. Our study revealed a consensus about the beneficial outcomes of TTL among those involved with the program. It supports the significant and ongoing value of widely implemented, multifaceted nursing leadership development programs and demonstrates that participants value their informal interactions as highly as they do the formal content. These findings have implications for delivery mode of similar professional development programs.

    This paper aims to investigate the relationship between factors that affecting the demand for broadband and the level of satisfaction. Previous researchers have found that the adoption of broadband is greatly influenced by many factors. Thus, in this study, a self-administered questionnaire was developed to obtain the factors affecting demand for broadband among broadband customers as well as their level of satisfaction. Pearson correlation, one-way analysis of variance (ANOVA) and t-test were used for statistical interpretation of the relationship. This study shows that there are better relationships between several factors over demand for broadband and satisfaction level.

    Chemotherapy has severe side effects in normal rapidly proliferating organs, such as hair follicles, and causes massive apoptosis in hair matrix keratinocytes followed by hair loss. To define the molecular signature of hair follicle response to chemotherapy, human scalp hair follicles cultured ex vivo were treated with doxorubicin (DXR), and global microarray analysis was performed 3 hours after treatment. Microarray data revealed changes in expression of 504 genes in DXR-treated hair follicles versus controls. Among these genes, upregulations of several tumor necrosis factor family of apoptotic receptors (FAS, TRAIL (tumor necrosis factor-related apoptosis-inducing ligand) receptors 1/2), as well as of a large number of keratin-associated protein genes, were seen after DXR treatment. Hair follicle apoptosis induced by DXR was significantly inhibited by either TRAIL-neutralizing antibody or caspase-8 inhibitor, thus suggesting a previously unreported role for TRAIL receptor signaling in mediating DXR-induced hair loss. These data demonstrate that the early phase of the hair follicle response to DXR includes upregulation of apoptosis-associated markers, as well as substantial reorganization of the terminal differentiation programs in hair follicle keratinocytes. These data provide an important platform for further studies toward the design of effective approaches for the management of chemotherapy-induced hair loss.

    Optical transparent and electrical conducting materials with broadband transmission are important for many applications in optoelectronic, telecommunications, and military devices. However, studies of broadband transparent conductors and their controlled modulation are scarce. In this study, we report that reversible transmittance modulation has been achieved with sandwiched nanocarbon thin films (containing carbon nanotubes (CNTs) and reduced graphene oxide (rGO)) via electrochemical alkali-ion intercalation/deintercalation. The transmittance modulation covers a broad range from the visible (450 nm) to the infrared (5 μm), which can be achieved only by rGO rather than pristine graphene films. The large broadband transmittance modulation is understood with DFT calculations, which suggest a decrease in interband transitions in the visible range as well as a reduced reflection in the IR range upon intercalation. We find that a larger interlayer distance in few-layer rGO results in a significant increase in transparency in the infrared region of the spectrum, in agreement with experimental results. Furthermore, a reduced plasma frequency in rGO compared to few-layer graphene is also important to understand the experimental results for broadband transparency in rGO. The broadband transmittance modulation of the CNT/rGO/CNT systems can potentially lead to electrochromic and thermal camouflage applications.

    Advances in broadband access are expected to exert a profound impact in our everyday life. It will be the key to the digital convergence of communication, computer and consumer equipment. A common thread that facilitates this convergence comprises digital media and Internet. To address this market, Equator Technologies, Inc., is developing the Dolphin broadband set-top box reference platform using its MAP-CA Broadband Signal ProcessorT chip. The Dolphin reference platform is a universal media platform for display and presentation of digital contents on end-user entertainment systems. The objective of the Dolphin reference platform is to provide a complete set-top box system based on the MAP-CA processor. It includes all the necessary hardware and software components for the emerging broadcast and the broadband digital media market based on IP protocols. Such reference design requires a broadband Internet access and high-performance digital signal processing. By using the MAP-CA processor, the Dolphin reference platform is completely programmable, allowing various codecs to be implemented in software, such as MPEG-2, MPEG-4, H.263 and proprietary codecs. The software implementation also enables field upgrades to keep pace with evolving technology and industry demands.

    2018-03-01

    Blocking broadband low-frequency airborne noises is highly desirable in lots of engineering applications, while it is extremely difficult to be realized with lightweight materials and/or structures. Recently, a new class of lightweight adaptive metamaterials with hybrid shunting circuits has been proposed, demonstrating super broadband structure-borne bandgaps. In this study, we aim at examining their potentials in broadband sound isolation by establishing an analytical model that rigorously combines the piezoelectric dynamic couplings between adaptive metamaterials and acoustics. Sound transmission loss of the adaptive metamaterial is investigated with respect to both the frequency and angular spectrum to demonstrate their sound-insulation effects. We find that efficient sound isolation can indeed be pursued in the broadband bi-spectrum for not only the case of the small resonator's periodicity where only one mode relevant to the mass-spring resonance exists, but also for the large-periodicity scenario, so that the total weight can be even lighter, in which the multiple plate-resonator coupling modes appear. In the latter case, the negative spring stiffness provided by the piezoelectric stack has been utilized to suppress the resonance-induced high acoustic transmission. Such kinds of adaptive metamaterials could open a new approach for broadband noise isolation with extremely lightweight structures.

    2015-12-01

    Structural biological materials have developed heterogeneous and hierarchical architectures that are responsible for the outstanding performance to provide protection against environmental threats including static and dynamic loading. Inspired by this observation, this research aims to develop new material and structural concepts for broadband vibration mitigation. The proposed composite materials possess a two-layered heterogeneous architecture where both layers consist of high-volume platelet-shape reinforcements and low-volume matrix, similar to the well-known “brick and mortar” microstructure of biological composites. Using finite element method, we numerically demonstrated that broadband wave attenuation zones can be achieved by tailoring the geometric features of the heterogeneous architecture. We reveal that the resulting broadband attenuation zones are gained by directly superimposing the attenuation zones in each constituent layer. This mechanism is further confirmed by the investigation into the phonon dispersion relation of each layer. Importantly, the broadband wave attenuation capability will be maintained when the mineral platelet orientation is locally manipulated, yet a contrast between the mineral platelet concentrations of the two constituent layers is essential. The findings of this work will provide new opportunities to design heterogeneous composites for broadband vibration mitigation and impact resistance under mechanically challenging environmental conditions.

    Summary The pharyngeal endoderm is hypothesized as the source of local signals that specify the identity of neural crest-derived mesenchyme in the arches. Sox9 is induced and maintained in pre-chondrogenic cells during condensation formation and endochondral ossification. Using explant culture we determined that pharyngeal endoderm was sufficient, but not necessary for specifying pre-chondrogenic identity, as surrounding tissues including the otic vesicle can compensate for signals from the pharyngeal endoderm. Multiple Fgf genes are expressed specifically in the pharyngeal endoderm subjacent to the neural crest-derived mesenchyme. FGF signaling is both sufficient and required for specification of Sox9 expression and specification of pre-chondrogenic identity, as demonstrated by the addition of recombinant FGF protein or the FGF receptor inhibitor (SU5402) to explanted tissue, respectively. However, FGF signaling cannot maintain Sox9 expression or initiate the chondrogenic program as indicated by the absence of Col2a1 transcripts. BMP4 signaling can induce and maintain Sox9 expression in isolated mesenchyme, but only in combination with FGF signaling induce Col2a1 expression, and thus, chondrogenesis. Given the spatio-temporal expression patterns of FGFs and BMPs in the pharyngeal arches, we suggest that this may represent a general mechanism of local signals specifying pre-chondrogenic identity and initiation of the chondrogenic program.

    Water samples from 58 rivers and streams across the United States were analyzed for pesticides as part of the National Water-Quality Assessment Program of the U.S. Geological Survey. The sampling sites represent 37 diverse agricultural basins, 11 urban basins, and 10 basins with mixed land use. Forty-six pesticides and pesticide degradation products were analyzed in approximately 2,200 samples collected from 1992 to 1995. The target compounds account for approximately 70 percent of national agricultural use in terms of the mass of pesticides applied annually. All the target compounds were detected in one or more samples. Herbicides generally were detected more frequently and at higher concentrations than insecticides. Nationally, 11 herbicides, 1 herbicide degradation product, and 3 insecticides were detected in more than 10 percent of samples. The number of target compounds detected at each site ranged from 7 to 37. The herbicides atrazine, metolachlor, prometon, and simazine were detected most frequently; among the insecticides, carbaryl, chlorpyrifos, and diazinon were detected the most frequently. Distinct differences in pesticide occurrence were observed in streams draining the various agricultural settings. Relatively high levels of several herbicides occurred as seasonal pulses in corn-growing areas. Several insecticides were frequently detected in areas where the dominant crops consist of orchards and vegetables. The number of pesticides detected and their concentrations were lower in wheat-growing areas than in most other agricultural areas. In most urban areas, the herbicides prometon and simazine and the insecticides carbaryl, chlorpyrifos, diazinon, and malathion were commonly detected. Concentrations of pesticides rarely exceeded standards and criteria established for drinking water, but some pesticides commonly exceeded criteria established for the protection of aquatic life.

    Structured programs have a positive impact on breastfeeding (BF) but have rarely been evaluated for preterm neonates, frequently combining prematurity and socioeconomic deprivation as risk factors of a low BF rate. We aimed to assess BF initiation rates in very preterm (preterm (33-36 weeks), and term neonates from 2002 to 2011 in a French administrative district characterized by socioeconomic deprivation. Structured activities to promote and support BF have been implemented in this area since 2002; they all started in neonatal units. This retrospective population-based study analyzed 302,102 first health certificates. Overall, the BF initiation rate significantly increased, from 52.9% [95% CI: (52.3; 53.4)] in 2002 to 61.0% [95% CI: (60.4; 61.6)] in 2011. In 2002, BF initiation rates did not differ between groups, but in 2011, it was higher for very preterm than for term and moderately preterm neonates [74.7% (69.7; 79.6)] vs. 60.9% (60.3; 61.5) and 59.9% (57.6; 62.2), respectively, both Ppreterm children and term-born children (P=0.40). The 2.2% yearly increase observed in very preterm neonates significantly differed from the 0.9% yearly increase in the French general population (Ppreterm neonates, but not in moderately preterm neonates, whose specific needs should be further evaluated.

    Bandwidth extension and thickness reduction are now the two key issues of cloaks. In this paper, we propose to achieve broadband, thin uni-directional electromagnetic (EM) cloaks using metasurfaces. To this end, a wideband flat focusing lens is firstly devised based on high-efficiency transmissive metasurfaces. Due to the nearly dispersionless parabolic phase profile along the metasurface in the operating band, incident plane waves can be focused efficiently after passing through the metasurface. Broadband unidirectional EM cloaks were then designed by combining two identical flat lenses. Upon illumination, the incident plane waves are firstly focused by one lens and then are restored by the other lens, avoiding the cloaked region. Both simulation and experiment results verify the broadband unidirectional cloak. The broad bandwidth and small thickness of such cloaks have potential applications in achieving invisibility for electrically large objects.

    When ultralight axion dark matter encounters a static magnetic field, it sources an effective electric current that follows the magnetic field lines and oscillates at the axion Compton frequency. We propose a new experiment to detect this axion effective current. In the presence of axion dark matter, a large toroidal magnet will act like an oscillating current ring, whose induced magnetic flux can be measured by an external pickup loop inductively coupled to a SQUID magnetometer. We consider both resonant and broadband readout circuits and show that a broadband approach has advantages at small axion masses. We estimate the reach of this design, taking into account the irreducible sources of noise, and demonstrate potential sensitivity to axionlike dark matter with masses in the range of 10^{-14}-10^{-6}  eV. In particular, both the broadband and resonant strategies can probe the QCD axion with a GUT-scale decay constant.

    We computationally study a subwavelength dielectric grating structure, show that slab waveguide modes can be used to obtain broadband high reflectivity, and analyze how slab waveguide modes influence reflection. A structure showing interference between Fabry-Perot modes, slab waveguide modes, and waveguide array modes is designed with ultra-broadband high reflectivity. Owing to the coupling of guided modes, the region with reflectivity R > 0.99 has an ultra-high bandwidth (Δf / ̅f > 30%). The incident-angle region with R > 0.99 extends over a range greater than 40°. Moreover, an asymmetric waveguide structure with a semiconductor substrate is studied.

    Interest in optics for hard X-ray broad-band application is growing. In this paper, we compare the hard X-ray (20-100 keV) reflectivity obtained with an energy-dispersive reflectometer, of a standard commercial gold thin-film with that of a 600 bilayer W/Si X-ray supermirror. The reflectivity...... that of the gold, Various other design options are discussed, and we conclude that continued interest in the X-ray supermirror for broad-band hard X-ray applications is warranted....

    Broadband light emitters operation, which covers multiple wavelengths of the electromagnetic spectrum, has been established as an indispensable element to the human kind, continuously advancing the living standard by serving as sources in important multi-disciplinary field applications such as biomedical imaging and sensing, general lighting and internet and mobile phone connectivity. In general, most commercial broadband light sources relies on complex systems for broadband light generation which are bulky, and energy hungry. \\tRecent demonstration of ultra-broadband emission from semiconductor light sources in the form of superluminescent light emitting diodes (SLDs) has paved way in realization of broadband emitters on a completely novel platform, which offered compactness, cost effectiveness, and comparatively energy efficient, and are already serving as a key component in medical imaging systems. The low power-bandwidth product is inherent in SLDs operating in the amplified spontaneous emission regime. A quantum leap in the advancement of broadband emitters, in which high power and large bandwidth (in tens of nm) are in demand. Recently, the birth of a new class of broadband semiconductor laser diode (LDs) producing multiple wavelength light in stimulated emission regime was demonstrated. This very recent manifestation of a high power-bandwidth-product semiconductor broadband LDs relies on interband optical transitions via quantum confined dot/dash nanostructures and exploiting the natural inhomogeneity of the self-assembled growth technology. This concept is highly interesting and extending the broad spectrum of stimulated emission by novel device design forms the central focus of this dissertation. \\tIn this work, a simple rate equation numerical technique for modeling InAs/InP quantum dash laser incorporating the properties of inhomogeneous broadening effect on lasing spectra was developed and discussed, followed by a comprehensive experimental analysis

    This paper describes the analysis of acoustic data taken from the VS45 at Kaiser-Wilhelm-Koog. The aim was to investigate the dependence of aerodynamic noise on tip speed and angle of attack. In particular, the dependence of noise in individual third octave bands on these variable is examined. The analysis is divided into 3 sections: data selection, data checks and analysis of broadband nacelle noise; analysis of broadband aerodynamic noise and its sensitivity to tip speed and angle of attack.

    The correlation integral has been studied in detail for broadband magnetic and density fluctuations observed in the TCA tokamak [Proceedings of the 11th Symposium on Fusion Technology (CEC, Luxembourg, 1981), Vol. I, p. 601]. These studies, which provide information on the correlation dimension ν, have shown no evidence for a low-dimensional attractor. It has therefore been concluded that the broadband fluctuations are associated either with a high-dimensional system (ν>10), or with a nonstationary state for which the concept of the correlation dimension has no meaning

    Broadband transparent electrodes based on 2D hybrid nanostructured Dirac materials between Bi2 Se3 and graphene are synthesized using a chemical vapor deposition (CVD) method. Bi2 Se3 nanoplates are preferentially grown along graphene grain boundaries as "smart" conductive patches to bridge the graphene boundary. These hybrid films increase by one- to threefold in conductivity while remaining highly transparent over broadband wavelength. They also display outstanding chemical stability and mechanical flexibility. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Sunscreens rely on multiple compounds to provide effective and safe protection against UV radiation. UV filters in sunscreens, in particular, provide broadband UV protection but are heavily linked to adverse health effects due to the generation of carcinogenic skin-damaging reactive oxygen species (ROS) upon solar irradiation. Herein, we demonstrate significant reduction in the ROS concentration by encapsulating an antioxidant photostabilizer with multiple UV filters into biobased ethyl cellulose nanoparticles. The developed nanoparticles display complete broadband UV protection and can form transparent and flexible films. This system therefore shows significant potential toward effective and safe nanoparticle-based UV protective coatings.

    Integrated into the work in health systems strengthening (HSS) is a growing focus on the importance of ensuring quality of the services delivered and systems which support them. Understanding how to define and measure quality in the different key World Health Organization building blocks is critical to providing the information needed to address gaps and identify models for replication. We describe the approaches to defining and improving quality across the five country programs funded through the Doris Duke Charitable Foundation African Health Initiative. While each program has independently developed and implemented country-specific approaches to strengthening health systems, they all included quality of services and systems as a core principle. We describe the differences and similarities across the programs in defining and improving quality as an embedded process essential for HSS to achieve the goal of improved population health. The programs measured quality across most or all of the six WHO building blocks, with specific areas of overlap in improving quality falling into four main categories: 1) defining and measuring quality; 2) ensuring data quality, and building capacity for data use for decision making and response to quality measurements; 3) strengthened supportive supervision and/or mentoring; and 4) operational research to understand the factors associated with observed variation in quality. Learning the value and challenges of these approaches to measuring and improving quality across the key components of HSS as the projects continue their work will help inform similar efforts both now and in the future to ensure quality across the critical components of a health system and the impact on population health.
