Sample records for border control measures

  1. Developing Effective Border Control

    International Nuclear Information System (INIS)

    Great progress that has been made in nuclear security measures for counter-proliferation capacity building for effective border controls. However, there is evidence that illicit transfers of military and dual-use items as well as the illicit trafficking of nuclear and other radioactive materials persist. Consequently, there remains an urgent need for continuing and enhancing effective border controls responsive to this threat. Developing and sustaining effective border controls for global defence to combat nuclear security threats is a complex challenge. Following a defence-in-depth approach, border control measures at official ports of entry and green and blue borders form one layer of a national nuclear detection architecture. It is important that the border control measures are both fully integrated into a comprehensive national strategy with achievable nuclear security program objectives and fully sustainable within the national infrastructure. The operations, maintenance and management of effective border control measures rely on a cyclic process of establishing objectives, design, implementation, training and evaluation. All relevant authorities and competencies engage in the process. The design is based on a full assessment of the nuclear security capabilities and associated infrastructure within the context of specific objectives within the national nuclear security strategy. A poor design or badly executed implementation can prevent the effective operation of the system in the short and long run. International cooperation and assistance play an important role in all aspects of developing effective border controls. Donor-recipient relations provide not only the requisite funds, but also the experience and technical expertise that promote effective and sustainable border controls. As the global detection architecture matures, many international organizations, such as International Atomic Energy Agency (IAEA), DOE, European Commission- Joint Research Centre

  3. Strengthening border control and management

    International Nuclear Information System (INIS)

    The world has experienced monumental changes in recent years. Globalization has brought many benefits. Business and commerce have increased and, as a result, brought us cheaper, more accessible goods from all regions of the world. We have access to relatively cheap and certainly much easier travel. We now live in a world of instant communications with mobile phones, laptops and 'BlackBerries'. However, there is a downside to globalization - transnationally organized crime and the reality of terrorism have grown. As more people cross borders, it is harder to detect criminals and terrorists. In the European Union, the internal borders of the now 27 member States have been dismantled. Effective international measures to counter organized crime and terrorist groups are of crucial importance. It is important to think globally and to act locally. The paper looks at some of the crime challenges and provides insight into the role and work of the United Nations Office on Drugs and Crime (UNODC) in drugs and crime control. It focuses on border control initiatives conducted by the UNODC. (author)

  5. Temporary reintroduction of border controls at French borders inside the Schengen Area

    CERN Multimedia

    2015-01-01

    The French authorities have informed CERN that, in view of the upcoming COP21 Paris Climate Conference, France will exceptionally reintroduce controls at its borders with Schengen states for one month from 13 November to 13 December 2015. All border posts and crossing points between France and Switzerland will be affected by this measure.   Members of the personnel are therefore reminded that, when crossing borders within the Schengen Area*, they must carry: either, in the case of citizens of European Economic Area (EEA) countries and Switzerland, an official identity document (identity card or passport); or, in the case of non-EEA and non-Swiss citizens, an identity document together with a Schengen visa if they are subject to this obligation, or an identity document together with a residence permit issued by a Schengen state** if they have one.   The French authorities will make every effort to limit the impact of this measure on cross-border traffic, and wish to thank the members of th...

  6. Usability in Public Services and Border Control

    Science.gov (United States)

    Pirelli, Giuliano

    The paper starts with a brief overview of the scale of disability and associated challenges and puts them in the context of the public policy on disability. It then analyses the usability challenges in public services and border control, including the issues of accessibility, safety and communication. These need to be addressed in future policy proposals, to provide the best assistance by new technologies to elderly people and people with disabilities, avoiding creating new barriers due to incorrect or incomplete initial conception. With increasing flux of novel security technology in mass transportation systems, and particularly the use of biometric identification in airports, the challenge of usability is recognized. This paper analyses these issues in the context of users with disability in an idealized process of Simplifying Passenger Travel (SPT).

    Earlier quantitative studies on cross-border regional integration processes have commonly neglected science, technology and innovation (STI) indicators: even the most notable example of a composite indicator approach to measuring cross-border regional integration, i.e. the Oresund index, lacks...... a sub-category for STI. Consequently, by ignoring cross-border innovation and knowledge flows, the Oresund integration index fails to take into account one of the most important drivers of economic growth in cross-border regions. Therefore, a new composite STI indicator (sub-category) was introduced...

  8. Inconsistency in precipitation measurements across the Alaska-Yukon border

    Science.gov (United States)

    Scaff, L.; Yang, D.; Li, Y.; Mekis, E.

    2015-12-01

    This study quantifies the inconsistency in gauge precipitation observations across the border of Alaska and Yukon. It analyses the precipitation measurements by the national standard gauges (National Weather Service (NWS) 8 in. gauge and Nipher gauge) and the bias-corrected data to account for wind effect on the gauge catch, wetting loss and trace events. The bias corrections show a significant amount of errors in the gauge records due to the windy and cold environment in the northern areas of Alaska and Yukon. Monthly corrections increase solid precipitation by 136 % in January and 20 % for July at the Barter Island in Alaska, and about 31 % for January and 4 % for July at the Yukon stations. Regression analyses of the monthly precipitation data show a stronger correlation for the warm months (mainly rainfall) than for cold month (mainly snowfall) between the station pairs, and small changes in the precipitation relationship due to the bias corrections. Double mass curves also indicate changes in the cumulative precipitation over the study periods. This change leads to a smaller and inverted precipitation gradient across the border, representing a significant modification in the precipitation pattern over the northern region. Overall, this study discovers significant inconsistency in the precipitation measurements across the USA-Canada border. This discontinuity is greater for snowfall than for rainfall, as gauge snowfall observations have large errors in windy and cold conditions. This result will certainly impact regional, particularly cross-border, climate and hydrology investigations.

  9. Dynamic data-driven sensor network adaptation for border control

    Bein, Doina; Madan, Bharat B.; Phoha, Shashi; Rajtmajer, Sarah; Rish, Anna

    2013-06-01

    Given a specific scenario for the border control problem, we propose a dynamic data-driven adaptation of the associated sensor network via embedded software agents which make sensor network control, adaptation and collaboration decisions based on the contextual information value of competing data provided by different multi-modal sensors. We further propose the use of influence diagrams to guide data-driven decision making in selecting the appropriate action or course of actions which maximize a given utility function by designing a sensor embedded software agent that uses an influence diagram to make decisions about whether to engage or not engage higher level sensors for accurately detecting human presence in the region. The overarching goal of the sensor system is to increase the probability of target detection and classification and reduce the rate of false alarms. The proposed decision support software agent is validated experimentally on a laboratory testbed for multiple border control scenarios.

    These principles have been applied to our air ambulance system based from Lanseria International Airport. By combining preventative and control measures, there has been no breach in our infection control strategies, as evidenced by no growth noted on specific and random swabs even when more and more ”super bugs” are being identified in hospital. As an air ambulance service flying patients from various African countries, we have the responsibility to conduct our own ”Border Security” to keep our hospitals, patients, aircraft and crews clean and safe. In this presentation we will share our ”Border Security” principles and experiences with the audience.

    2016-01-01

    During the 2014-2016 Ebola virus disease (Ebola) epidemic in West Africa, CDC implemented travel and border health measures to prevent international spread of the disease, educate and protect travelers and communities, and minimize disruption of international travel and trade. CDC staff provided in-country technical assistance for exit screening in countries in West Africa with Ebola outbreaks, implemented an enhanced entry risk assessment and management program for travelers at U.S. ports of entry, and disseminated information and guidance for specific groups of travelers and relevant organizations. New and existing partnerships were crucial to the success of this response, including partnerships with international organizations, such as the World Health Organization, the International Organization for Migration, and nongovernment organizations, as well as domestic partnerships with the U.S. Department of Homeland Security and state and local health departments. Although difficult to assess, travel and border health measures might have helped control the epidemic's spread in West Africa by deterring or preventing travel by symptomatic or exposed persons and by educating travelers about protecting themselves. Enhanced entry risk assessment at U.S. airports facilitated management of travelers after arrival, including the recommended active monitoring. These measures also reassured airlines, shipping companies, port partners, and travelers that travel was safe and might have helped maintain continued flow of passenger traffic and resources needed for the response to the affected region. Travel and border health measures implemented in the countries with Ebola outbreaks laid the foundation for future reconstruction efforts related to borders and travel, including development of regional surveillance systems, cross-border coordination, and implementation of core capacities at designated official points of entry in accordance with the International Health Regulations

    2010-01-01

    Background: Dermoscopy is one of the major imaging modalities used in the diagnosis of melanoma and other pigmented skin lesions. Due to the difficulty and subjectivity of human interpretation, dermoscopy image analysis has become an important research area. One of the most important steps in dermoscopy image analysis is the automated detection of lesion borders. Although numerous methods have been developed for the detection of lesion borders, very few studies were comprehensive in the evaluation of their results. Methods: In this paper, we evaluate five recent border detection methods on a set of 90 dermoscopy images using three sets of dermatologist-drawn borders as the ground-truth. In contrast to previous work, we utilize an objective measure, the Normalized Probabilistic Rand Index, which takes into account the variations in the ground-truth images. Conclusion: The results demonstrate that the differences between four of the evaluated border detection methods are in fact smaller than those predicted by ...

  19. Measuring border irregularities of skin lesions using fractal dimensions

    1996-09-01

    Malignant melanoma is the most common cancer in people less than 35 years of age and incident rates are increasing by approximately 5 percent per annum in many white populations, including British Columbia, Canada. In 1994, a clinical study has been established to digitize melanocytic lesions under a controlled environment. Lesions are digitized from patients who are referred to the Colored Pigment Lesion Clinic in the University of British Columbia. In this paper, we investigate how to use fractal dimensions (FDs) in measuring the irregularity of a skin lesion. In a previous project, we have experimented with 6 different methods to calculate fractal dimensions on a small number of images of skin lesions, and the simple box-counting method performed the best. However, the method did not exploit the intensity information of the images. With the new set of images which are digitized under the controlled environment, we utilize the differential box counting method to exploit such information. Four FD measures, including the direct FD, the horizontal and the vertical smoothing FDs, and the multi- fractal dimension of order two, are calculated based on the original color images. In addition, these 4 FD features are repeatedly calculate for the blue band of the images. This paper reports the different features through the calculations of the fractal dimensions and compares their differentiation power in the use of diagnosis of images of skin lesions.

  20. Managing Migration: Is border control fundamental to anti-trafficking and anti-smuggling interventions?

    Directory of Open Access Journals (Sweden)

    Rebecca Miller

    2013-09-01

    Full Text Available Over the last several decades, globalisation and a growing concern over security issues, including transnational crime and terrorism, has shaped migration policies and the priorities of states. As migration rose to the top of many government agendas, a rapid tightening and regularisation of borders ensued in an attempt to keep undesirable, high-risk migrants out of potential destination countries. Concomitantly, transnational crimes, such as trafficking in persons and the smuggling of migrants, have been increasingly defined as border security problems. This article examines the extent to which border control is fundamental to anti-trafficking and anti-smuggling interventions, situating the debate within the wider nexus of globalisation and the securitisation of migration. Based upon their work with the United Nations Office on Drugs and Crime (UNODC Regional Centre for Southeast Asia and the Pacific, the authors take the standpoint that given it is the sovereign right of each state to control its border and regulate migration, the human rights of migrants must be considered within this realpolitik. Clearly, though, this claim is highly political and contentious. In the article, we explore some of the tensions and contradictions that have emerged in this debate, and then develop an argument to suggest that it is possible for states to combine managed migration and strict border controls with the protection of human rights in the current context of globalisation.

  1. Surveillance Unattended Foliage Penetrating Radar for Border Control and Homeland Protection

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available The increasing request for safety, security and environment protection at local and national level reveal the deficiency of the traditional surveillance and control centers to satisfy the needs and requirements of modern border control systems for homeland protection where land border is expected to be monitored as well as the maritime one. This is, for instance, the case of any land border affected by hidden immigration and/or illegal traffics as well as any small areas such as critical infrastructures or military/ civilian posts in forest or jungle environment characterized by vegetation. In such challenging environment, logistics constraints strongly recommend to have very low power devices able to operate months or years without maintenance. A such scenario should be the perfect place for implementing an Unattended Ground Sensors (UGS network making use FOliage PENetration (FOPEN radar for border control. The paper aims to present the basic characteristics and preliminary results of a Surveillance Unattended FOPEN (SUF radar suitable for detecting moving targets, people or vehicles, in dense forest environment.

  2. Threat of nuclear terrorism: Issues of international law, border protection, security and export control cooperation

    International Nuclear Information System (INIS)

    In 1970-1991 the IAEA dealt mainly with loyal signatories to NPT, after 1991 met challenges of non-loyal states aiming at clandestine nuclear programs (Iraq and North Korea), while after 2001 must also meet new challenge of non-loyal non-state actors aiming at obtaining nuclear materials and weapons. The task of protecting 450 tons of separated weapon grade plutonium, 1700 tons of separated HEU outside military use, as well as 2,7 tons of HEU in civilian and training reactors spread in 43 countries requires more active cooperation between the IAEA and state and inter-state structures responsible for fight against international crime, intelligence, control of borders and domestic law and order. UN SC resolutions 1269, 1368, 1373 provide some important legal basis for fight against nuclear terrorism, but special Convention on Fight Against Nuclear Terrorism need to be adopted through UN procedures. Protocol on Fight against International terrorism is required to supplement the Palermo (2000) Convention on Fight Against Transnational Organized Crime (signed as for now by 128 states). Treaty on Cooperation in Fight against Terrorism signed by the CIS states in 1999, as well as creation of the CIS Anti-Terrorist Center in 2000 could contribute to the legal means of such fight. Russia also employs Bishkek security group (within Shanghai Cooperation Organization) and 'Borjomi Four' group (security services cooperation between Russia, Armenia, Georgia, Azerbaijan) for anti-terrorist coordination. Obligations under START-1, START-II and other treaties on nuclear disarmament require from Russia to dismantle in foreseeable future about 250 nuclear reactors from submarines, about 700 SLBMs, about 150 ICBMs of SS-18 type and 400 more of other types. All that would increase stocks of fissile material beyond direct military use and would require additional protection measures. In time this task coincides for Russia with necessity to reprocess 40,000 tons of chemical weapons (task

  3. The “Fake Marriage” Test in Taiwan: Gender, Sexuality, and Border Control

    Directory of Open Access Journals (Sweden)

    Mei-Hua Chen

    2015-06-01

    Full Text Available According to many reports, migrant sex workers often use marriages of convenience to cross national borders in order to avoid laws criminalizing commercial sex in many destination countries. Taiwan is one of the countries developing strategies to prevent this illicit migration, particularly through the application of a fake marriage test. Based on in-depth interviews with eighteen Chinese migrant sex workers and thirteen officers of Taiwan’s National Immigration Agency (NIA, this article argues, first, that the discourse of “national security” has been widely drawn on to justify Taiwan’s rigid border control at the expense of stigmatized Chinese prostitutes who have been scapegoated. Border control is therefore not only racialized or classed but also sexualized, to the extent that all Chinese migrant women are considered potential prostitutes. Second, this article reveals how the exclusion of and hostility toward Chinese sex workers are simultaneously linked with a gender regime that seeks to exclude Chinese spouses who deviate from Taiwanese gender and social norms. The border is therefore a contested site where gender, sexuality, and nationality are interwoven.

  4. Networked solutions of radiation control of state borders and urban areas

    International Nuclear Information System (INIS)

    Full text: Prevention of illicit trafficking in radioactive and nuclear materials through state borders as well as the disperse of radioactive materials in urban area is a challenging task of national security departments in many countries. To solve this task, appropriate actions of personnel on-site equipped by radiation detectors such as fixed radiation portal monitors or mobile personal radiation detectors are required. However, users of radiation equipment such as Customs, Border Guard and Police Services often perform radiation control as additional responsibility to their main duties. Furthermore, these users have no sufficient expertise in radiation control and need real-time remote expert help to interpret readings of radiation equipment and expert support in decision making process. Polimaster has developed complete solution called Nuclear Protection Network system (NPNET) for high-effective radiation control on State Borders as well as inside a country. NPNET system intended for efficient interaction and on-line data exchange between a user, radiation control instrument, for example a personal radiation detector or radioisotope identifier, and remote Command Center. Availability of such system allows to solve more efficiently tasks of detection, localization and identification of ionizing radiation sources, to properly interpret false alarms (e.g. at detention of a passenger having passed radio-therapy etc.) and effectively prevent illicit trafficking radioactive and nuclear materials. The NPNET system can cover territory as large as city or even a state and provides assistant of infinite number of independent user groups. NPNET has a module structure and could be easily adapted to any specific user's requirements. Thus, the radiation mobile system NPNET is an effective tool for prevention of illicit trafficking of nuclear and radioactive materials and is recommended for use by Border guards, Customs, Securities and emergency situations services.

  5. A BMP regulatory network controls ectodermal cell fate decisions at the neural plate border.

    Science.gov (United States)

    Reichert, Sabine; Randall, Rebecca A; Hill, Caroline S

    2013-11-01

    During ectodermal patterning the neural crest and preplacodal ectoderm are specified in adjacent domains at the neural plate border. BMP signalling is required for specification of both tissues, but how it is spatially and temporally regulated to achieve this is not understood. Here, using a transgenic zebrafish BMP reporter line in conjunction with double-fluorescent in situ hybridisation, we show that, at the beginning of neurulation, the ventral-to-dorsal gradient of BMP activity evolves into two distinct domains at the neural plate border: one coinciding with the neural crest and the other abutting the epidermis. In between is a region devoid of BMP activity, which is specified as the preplacodal ectoderm. We identify the ligands required for these domains of BMP activity. We show that the BMP-interacting protein Crossveinless 2 is expressed in the BMP activity domains and is under the control of BMP signalling. We establish that Crossveinless 2 functions at this time in a positive-feedback loop to locally enhance BMP activity, and show that it is required for neural crest fate. We further demonstrate that the Distal-less transcription factors Dlx3b and Dlx4b, which are expressed in the preplacodal ectoderm, are required for the expression of a cell-autonomous BMP inhibitor, Bambi-b, which can explain the specific absence of BMP activity in the preplacodal ectoderm. Taken together, our data define a BMP regulatory network that controls cell fate decisions at the neural plate border.

  7. Airport Casualties: Non-Admission and Return Risks at Times of Internalized/Externalized Border Controls

    Directory of Open Access Journals (Sweden)

    Maybritt Jill Alpes

    2015-09-01

    Full Text Available This article analyzes what can happen to forced returnees upon arrival in their country of nationality. Subjective configurations of state agents in the Global South have created return risks, which in turn transform subjectivities of post-colonial citizens. The article contributes to this Special Issue by tracing repercussions of the externalization and internalization of border controls. In the case of Cameroon, these connections have resulted in the criminalization of emigration. Aspiring migrants are prosecuted if their departure projects fail to respect the entry requirements of countries in the Global North. The article is based on research conducted in Douala, Cameroon, in the form of discussions with control agents at the international airport, investigations at a prison, a review of related case law, police registers and interviews with Cameroonians returnees (November 2013–January 2014. Border controls and connected anti-fraud programs suppress family-based forms of solidarity and allow only for subjectivities rooted in state-managed forms of national identity. The article illustrates how efforts to combat fraud fuel corruption in returnees’ social networks, whereby, instead of receiving remittances, families in emigration countries have to mobilize financial resources in order to liberate returnees from police stations or prison complexes. Migration related detention of nationals in the Global South highlights the growing significance of exit controls in migration management.

  9. Border control for stowaway alien species should be prioritised based on variations in establishment debt.

    Science.gov (United States)

    Faulkner, Katelyn T; Robertson, Mark P; Rouget, Mathieu; Wilson, John R U

    2016-09-15

    Border control is one of the major approaches used by countries to limit the number of organisms introduced as stowaways. However, it is not feasible to inspect all passengers, cargo and vehicles entering a country, and so efforts need to be prioritised. Here we use South Africa as a case study to assess, based on tourism and trade data and climate matching techniques, the number of stowaway species that might be introduced ('colonisation pressure') and the likelihood that once introduced, these organisms will establish ('likelihood of establishment'). These results were used to explore how the number of species that are likely to establish ('establishment debt') varies across donor regions and seasons. A simple theoretical model was then used to compare four strategies for prioritising border control inspections: no prioritisation; based on colonisation pressure; based on likelihood of establishment; and based on both colonisation pressure and likelihood of establishment. Establishment debt was greatest in southern hemisphere spring and autumn when South Africa is climatically similar to northern hemisphere countries with which there are strong, consistent trade and tourism links (i.e. colonisation pressure varied little seasonally, but likelihood of establishment did vary across the seasons). Prioritising inspections based on both colonisation pressure and the likelihood of establishment was clearly the most effective strategy, with this strategy detecting at least 6% more potential invaders than the other strategies. While there are many practical limitations to the implementation of such prioritised inspection strategies, the results highlight the importance of national and regional studies of establishment debt.

  10. Europe facing climate change - a border adjustment measure to prepare the after-Kyoto?

    International Nuclear Information System (INIS)

    Considering the different relationships between the trade framework and that of the struggle against climate change, the authors address the European Union (EU) environmental strategy within the perspective of a multilateral governance of climate changes for the after-Kyoto period. After having recalled what is at stake in a border adjustment measure and outlined the difficulties of implementation of a tax-based solution at a multilateral level, the authors present the available strategies for the EU. Then, they address the strategy based on trade liberalization as incentive to the struggle against climate changes. They discuss the derogation to standard rules and finally propose a governance system between the United Nations Framework Convention on Climate Change (UNFCCC or FCCC) and the WTO

  11. The Transcription Factor NIN-LIKE PROTEIN7 Controls Border-Like Cell Release.

    Science.gov (United States)

    Karve, Rucha; Suárez-Román, Frank; Iyer-Pascuzzi, Anjali S

    2016-07-01

    The root cap covers the tip of the root and functions to protect the root from environmental stress. Cells in the last layer of the root cap are known as border cells, or border-like cells (BLCs) in Arabidopsis (Arabidopsis thaliana). These cells separate from the rest of the root cap and are released from its edge as a layer of living cells. BLC release is developmentally regulated, but the mechanism is largely unknown. Here, we show that the transcription factor NIN-LIKE PROTEIN7 (NLP7) is required for the proper release of BLCs in Arabidopsis. Mutations in NLP7 lead to BLCs that are released as single cells instead of an entire layer. NLP7 is highly expressed in BLCs and is activated by exposure to low pH, a condition that causes BLCs to be released as single cells. Mutations in NLP7 lead to decreased levels of cellulose and pectin. Cell wall-loosening enzymes such as CELLULASE5 (CEL5) and a pectin lyase-like gene, as well as the root cap regulators SOMBRERO and BEARSKIN1/2, are activated in nlp7-1 seedlings. Double mutant analysis revealed that the nlp7-1 phenotype depends on the expression level of CEL5 Mutations in NLP7 lead to an increase in susceptibility to a root-infecting fungal pathogen. Together, these data suggest that NLP7 controls the release of BLCs by acting through the cell wall-loosening enzyme CEL5.

    Background Understanding contemporary socio-cultural stressors may assist educational, clinical and policy-level health promotion efforts. This study presents descriptive findings on a new measure, the Border Community & Immigration Stress Scale (BCISS). Methods The data were from two community surveys as part of community based participatory projects conducted in the Southwestern US border region. This scale includes stressful experiences reflected in extant measures, with new items reflecting heightened local migration pressures and health care barriers. Results Stressors representing each main domain, including novel ones, were reported with frequency and at high intensity in the predominantly Mexican-descent samples. Total stress was also significantly associated with mental and physical health indicators. Discussion The study suggests particularly high health burdens tied to the experience of stressors in the US border region. Further, many of the stressors are also likely relevant for other communities within developed nations also experiencing high levels of migration. PMID:22430894

    As a public health strategy in responding to epidemics, sanitary checks at borders to delay the entry of the pandemic virus into Spain are part of the containment phases activities. Their implementation is the responsibility of the Foreign Health Department and requires a coordinated action with other agencies involved in the response. This paper describes the actions undertaken at international airports during these phases and evaluates its efficacy in the execution of their objective. We establish a hypothesis to explain how the measures undertaken by Foreign Health and the collaboration with the National Surveillance System may have contributed to delay the spread of the virus into our country. We want to emphasize the need for consolidating the border control surveillance system and improving collaboration, as well as the importance of designing a clear communication strategy for the population in these settings. Together these measures, along with others, will prevent situations of uncertainty. PMID:21203716

    2016-01-01

    Photographic identity documents (IDs) are commonly used despite clear evidence that unfamiliar face matching is a difficult and error-prone task. The current study set out to examine the performance of seven individuals with extraordinary face recognition memory, so called "super recognisers" (SRs), on two face matching tasks resembling border control identity checks. In Experiment 1, the SRs as a group outperformed control participants on the "Glasgow Face Matching Test", and some case-by-case comparisons also reached significance. In Experiment 2, a perceptually difficult face matching task was used: the "Models Face Matching Test". Once again, SRs outperformed controls both on group and mostly in case-by-case analyses. These findings suggest that SRs are considerably better at face matching than typical perceivers, and would make proficient personnel for border control agencies.

    2011-08-01

    Full Text Available The main security problem that any state faces today is protecting itscitizens in countering organised crime and terrorism. Wars between states are lessfrequent than in previous eras. Border defence and border security are distinctmissions requiring different forces with different training and different equipment.Border defence is predominately against the armed forces of other states requiringtanks, aircraft and ships. Traditionally, border security includes the mission roles ofimmigration, crime, agriculture, finance, disease control and terrorism. Intelligencegathering and analysis using three methodologies - trends and patterns, frequency,and probability – provides a solution to the large and expensive armed forces forterritorial border defence and defines the ability to succeed in border security.

  1. Radioactivity measurements and control solutions

    International Nuclear Information System (INIS)

    In our department, in the last years, a new line of production has been developed devoted to the radioactivity measurements (portal monitor, gamma source detector, neutron monitor). Instruments of different design (hand-held, portals or steady-state) are intended for detection and locating of radioactive sources. Monitors are intended to detect radioactive and special nuclear materials in vehicles, pedestrians, luggage, as well as for illegal traffic prevention of radioactive sources. Monitors provide audio and visual alarm signals when radioactive and/or special nuclear materials are detected. Neutron dosimeters are designed for the determination of dose equivalent rate around neutron generators or sources. All devices can be recommended for use to officers of customs, border guard and emergency services, civil defense, fire brigades, police and military departments, nuclear research or power facilities. Incorporating micro controllers and new design, our products span almost all the spectra of radioactivity detection (gamma, beta, X and neutrons). No special knowledge is needed to operate these instruments as all service functions are performed automatically (self-tests, background updating and threshold calculation). The Portal monitor is intended to be a checkpoint in contamination control or in unauthorized traffic of radioactive materials. The portal monitor can be installed both in open, unprotected to environmental conditions areas or in enclosed areas. It may be used at pedestrian cross border points, at check points of Nuclear Power Plants, enterprises of nuclear industry, weapons manufacturing and storage plants, nuclear waste disposal and storage sites, at the entrances to steel plants, the post-offices and airports, the governmental offices, banks, private companies etc. The monitor provides audio alarming signals when radioactive and/or special nuclear materials are detected. The monitor consists in a portal frame, which sustains 5 detectors. Each

    Several thousand young Americans visit the bars in Tijuana, Mexico, each weekend night, raising concerns on both sides of the border. Measures implemented in San Diego, California, and Tijuana have successfully reduced the number of American visitors to Mexican bars. Although San Diego policies have been well-documented, this is the first article on investigation of measures enacted south of the border. Information on Tijuana alcohol policies was obtained from a survey of 29-36 bars from 1997 to 1999. The Tijuana police provided data on Americans arrested in Tijuana from 1998 to 1999. Our study found alcohol regulations are poorly enforced in Tijuana, suggesting that regulatory agencies are captured by bar owners. However, such a capture may be weakening. The importance of identifying and supporting Mexican interest groups, as opposed to the bar owners, as a mechanism to impede the capture of Tijuana's regulatory agencies is discussed. The number of Americans involved in alcohol-related crimes in Tijuana sharply decreased over time. However, such a success is largely related to the success of the San Diego efforts in reducing the number of American visitors to Tijuana. Also, by demonstrating the racial/ethnic heterogeneity of American visitors to Tijuana bars, our study points out the need for prevention policies designed north of the border to take such heterogeneity into account.

  9. Metrics for border management systems.

    Duggan, Ruth Ann

    2009-07-01

    There are as many unique and disparate manifestations of border systems as there are borders to protect. Border Security is a highly complex system analysis problem with global, regional, national, sector, and border element dimensions for land, water, and air domains. The complexity increases with the multiple, and sometimes conflicting, missions for regulating the flow of people and goods across borders, while securing them for national security. These systems include frontier border surveillance, immigration management and customs functions that must operate in a variety of weather, terrain, operational conditions, cultural constraints, and geopolitical contexts. As part of a Laboratory Directed Research and Development Project 08-684 (Year 1), the team developed a reference framework to decompose this complex system into international/regional, national, and border elements levels covering customs, immigration, and border policing functions. This generalized architecture is relevant to both domestic and international borders. As part of year two of this project (09-1204), the team determined relevant relative measures to better understand border management performance. This paper describes those relative metrics and how they can be used to improve border management systems.

    Research examining border crossing and health has focused on substance abuse, healthcare utilization and air pollution. Living in border communities allows for frequent crossing and exposure to different sociocultural and structural environments. Given high rates of obesity among Latinos and the large percentage living in border communities, it is important to consider the relationship between border crossing and obesity. This study explored the relationship between frequency of border crossing, obesigenic behaviors, measured obesity, and chronic disease. Multistage sampling methods were used to recruit 397 Latino adults living in border communities in South San Diego County. Selected participants completed a face-to-face interview and height and weight measurements. More frequent border crossing was associated with more fast food consumption and a greater reported diagnosis of high cholesterol. Understanding the extent to which border crossing is associated with obesigenic behaviors and chronic disease is important for developing relevant interventions along the border. PMID:24442511

  12. Modern technical and technological solutions of radiation control to combat illicit trafficking of nuclear and radioactive materials across borders

    International Nuclear Information System (INIS)

    Full text: Preventing the illicit nuclear and radioactive materials transportation across the state borders has recently taken on a special significance due to ongoing threat of utilizing these materials for terrorist purposes. Currently more and more countries are gaining better understanding of the importance of creating the national security system. It is obvious that the threat of nuclear terrorism is not the only reason to stimulate these efforts and actions. Another reason is existence of 'orphan' sources which number in the world is approaching to 200 000 including the ones with a very high activity. Uncontrolled presence of such sources and materials in the human environment can be hazardous to human health and it may cause significant economical losses. Radiation control at the borders of the countries in this case is the first line of defense on the route of illicit nuclear and radioactive material movement and therefore vitally important for country/state radiation protection. Radiation control at the borders of the states requires three steps: 1) primary control or detecting the presence of radioactive sources on a controlled object; 2) additional radiation control or locating the exact place of the radioactive source on the person, within the vehicle or inside the container; 3) identification of the nature of the radioactive source. To accomplish the first and the main step of radiation control process the high sensitive gamma-neutron portal monitors operating in automatic mode are utilized. They are used to alert authorities to the appearance of any radioactive source in the controlled area. These monitors are developed and manufactured in some countries and currently deployed at the borders of the countries and also in areas where the radioactive sources may appear. However, the experience of deploying the portal monitors in various countries (Poland, Russia, Belarus) (1-3) has proved that the installation even the best of the best monitors is just

  13. Radiation measurements and quality control

    International Nuclear Information System (INIS)

    Accurate measurements are essential to research leading to a successful radiation process and to the commissioning of the process and the facility. On the other hand, once the process is in production, the importance to quality control of measuring radiation quantities (i.e., absorbed dose, dose rate, dose distribution) rather than various other parameters of the process (i.e. conveyor speed, dwell time, radiation field characteristics, product dimensions) is not clearly established. When the safety of the product is determined by the magnitude of the administered dose, as in radiation sterilization, waste control, or food preservation, accuracy and precision of the measurement of the effective dose are vital. Since physical dose measurements are usually simpler, more reliable and reproducible than biological testing of the product, there is a trend toward using standardized dosimetry for quality control of some processes. In many industrial products, however, such as vulcanized rubber, textiles, plastics, coatings, films, wire and cable, the effective dose can be controlled satisfactorily by controlling process variables or by product testing itself. In the measurement of radiation dose profiles by dosimetry, it is necessary to have suitable dose meter calibrations, to account for sources of error and imprecision, and to use correct statistical procedures in specifying dwell times or conveyor speeds and source and product parameters to achieve minimum and maximum doses within specifications.

  14. Stress controlled magma-earthquake interaction during unrest at Chiles-Cerro Negro Volcanoes (Ecuador-Colombian border)

    The movement of fluids beneath a volcano can cause deformation, and therefore changes to the subsurface stress field that manifest in swarms of low magnitude (Chiles-Cerro Negro volcanoes on the Ecuador-Colombian border. These volcanoes were previously considered to be historically inactive, but between 2013 and early 2015 there were three episodes of unrest characterised by VT swarms of increasing energy and duration. GPS measurements at two stations near Volcán Chiles show inflation over a time period of approximately twenty days prior to the 20th October, consistent with the intrusion of magma at half space depths >13 km. This inflation took place during a swarm of VT seismicity with thousands of low magnitude events per day and culminated in a M 5.6 earthquake on the 20th October, when inflation abruptly ceased. We measure coseismic displacements from the M 5.6 earthquake with data from three independent InSAR platforms and find that they are consistent with shallow slip of 1.2 m on an oblique reverse fault. This fault plane would have experienced positive Coulomb stress changes from some of the range of potential sources consistent with the inflation. Magmatic intrusion could therefore have contributed to the loading on the fault directly through stress changes caused by pressurisation, and indirectly through the decrease in effective friction coefficient due to elevated pore fluid pressure. The cessation of inflation immediately after the moderate earthquake suggests a link between the two events. We expect slip on the fault plane identified from the InSAR data to have resulted in compression in the shallow crust south of Volcán Chiles, above the source that had previously been inflating. This would have inhibited further ascent of magma. The Chiles-Cerro Nego unrest provides rare observations of interaction between magmatic intrusion and a moderate earthquake during volcanic unrest.

  15. Identification of Novel Regulators of the JAK/STAT Signaling Pathway that Control Border Cell Migration in the Drosophila Ovary

    Science.gov (United States)

    Saadin, Afsoon; Starz-Gaiano, Michelle

    2016-01-01

    The Janus Kinase/Signal Transducer and Activator of Transcription (JAK/STAT) signaling pathway is an essential regulator of cell migration both in mammals and fruit flies. Cell migration is required for normal embryonic development and immune response but can also lead to detrimental outcomes, such as tumor metastasis. A cluster of cells termed “border cells” in the Drosophila ovary provides an excellent example of a collective cell migration, in which two different cell types coordinate their movements. Border cells arise within the follicular epithelium and are required to invade the neighboring cells and migrate to the oocyte to contribute to a fertilizable egg. Multiple components of the STAT signaling pathway are required during border cell specification and migration; however, the functions and identities of other potential regulators of the pathway during these processes are not yet known. To find new components of the pathway that govern cell invasiveness, we knocked down 48 predicted STAT modulators using RNAi expression in follicle cells, and assayed defective cell movement. We have shown that seven of these regulators are involved in either border cell specification or migration. Examination of the epistatic relationship between candidate genes and Stat92E reveals that the products of two genes, Protein tyrosine phosphatase 61F (Ptp61F) and brahma (brm), interact with Stat92E during both border cell specification and migration.

  16. Radiation measurements and quality control

    International Nuclear Information System (INIS)

    The association between radiation measurements and quality control is established for radiation sterilization of medical products and food irradiation. Good quality control implies accurate radiation dosimetry and a discussion of the factors which can affect the accuracy of in-plant dosimetry is presented. It is argued that if systematic errors are to be avoided in in-plant dosimetry the plant operators will have to spend more time and effort in developing the skills associated with the accurate use of radiation dosemeter systems. The aims and merits of an international intercomparison programme recently set up by the IAEA are discussed. The benefits of accurate in-plant dosimetry for the operator, approving authority and purchaser are balanced against the extra dosimetric efforts required for good quality control. (author)

    Due to the geographical, cultural, economic, political and legal factors, there are a lot of illegal cross-border marriages in the border area of Yunnan Province. Those foreign women, illegally married to Chinese, become "de facto citizens" in China but as "three non-staff", their "identity" and "equity" are not recognized and guaranteed. This triggered a series of problems which affected the social stability in the border area. The cross-border marriage is one way to relieve the domestic contradictory in marriage situations, so a good management of this special cross-border marriage among border citizens is extremely important to maintain the stability and build harmony in border area. This paper researches the cross-border marriages in three typical villages bordering Vietnam, Laos and Myanmar; analyzes their characteristics and problems; and proposes corresponding counter-measures for the cross-border marriage and harmony in the border area.%由于地理、文化、经济、政治、法律等因素在云南边境地区存在大量非法的跨国婚姻,这些嫁入中国的外籍妇女成为我国"事实上的公民",但在法律为"三非人员",其"身份"与"权益"得不到认可和保障,引发了一系列影响边境稳定的社会问题.云南边境跨国婚姻具有缓解国内婚姻市场矛盾的作用,抓好具有独特性状的边民跨国婚姻管理,对维护社会稳定、构建和谐边疆具有极其重要的意义.本文通过实地调研与越南、老挝、缅甸接壤的三个典型边境村寨,分析云南边境跨国婚姻的特点和存在的问题,并对解决边民跨境通婚问题与构建和谐边疆提出对策建议.

    For the most rapidly growing economic entity in the world, China, a new logistics operation called the indirect cross-border supply chain model has recently emerged. The primary idea of this model is to reduce logistics costs by storing goods at a bonded warehouse with low storage cost in certain Chinese regions, such as the Pearl River Delta (PRD). This research proposes a performance measurement system (PMS) framework to assess the direct and indirect cross-border supply chain models. The PMS covers four categories including cost, time, quality and flexibility in the assessment of the performance of direct and indirect models. Furthermore, a survey was conducted to investigate the logistics performance of third party logistics (3PLs) at the PRD regions, including Guangzhou, Shenzhen and Hong Kong. The significance of the proposed PMS framework allows 3PLs accurately pinpoint the weakness and strengths of it current operations policy at four major performance measurement categories. Hence, this helps 3PLs further enhance the competitiveness and operations efficiency through better resources allocation at the area of warehousing and transportation.

    Pulses to steer the time evolution of quantum systems can be designed with optimal control theory. In most cases it is the coherent processes that can be controlled and one optimizes the time evolution towards a target unitary process, sometimes also in the presence of non-controllable incoherent processes. Here we show how to extend the GRAPE algorithm in the case where the incoherent processes are controllable and the target time evolution is a non-unitary quantum channel. We perform a grad...

  9. Surveillance and Control of Aedes albopictus in the Swiss-Italian Border Region: Differences in Egg Densities between Intervention and Non-intervention Areas.

    2016-01-01

    Full Text Available Aedes albopictus, the Asian tiger mosquito, originates from the tropical and subtropical regions of Southeast Asia. Over the recent decades it has been passively spread across the globe, primarily through the used tyre trade and passive transportation along major traffic routes. A. albopictus is a proven vector for many arboviruses, most notably chikungunya and dengue, with recent outbreaks also in continental Europe. In southern Switzerland, in the Canton of Ticino A. albopictus was spotted for the first time in 2003. Since then the local authorities have implemented a control programme based on larval source reduction. Despite these efforts, mosquito densities have increased over the last decade, casting doubts on the effectiveness of such larval control programmes.The Italian communities just across the Swiss-Italian border lack a control programme. This motivated us to compare the intervention and the non-intervention areas side by side in an attempt to find evidence for, or against, the effectiveness of larval A. albopictus control. Using ovitraps and a randomised sampling scheme, we examined the seasonal and spatial abundance of A. albopictus in sylvatic and urban environments across the Swiss-Italian border in 2012 and 2013. In the urban environments of the non-intervention area, egg densities were 2.26 times higher as compared to the intervention area. In the sylvatic environments, as compared to the urban environments, egg densities were 36% in the intervention area and 18% in the non-intervention area.Though alternative explanations are also valid, the results support the hypothesis that the Ticino intervention programme does have an impact. At the same time the data also suggest that current larval interventions fall short in gaining full control over the mosquito, calling for the evaluation of additional, or alternative, approaches. Ideally, these should also consider inclusion of the neighbouring Italian communities in the

    The Indo-Gangetic Plains (IGP) in northern South Asia are among the most polluted and most densely populated places in the world, and they are upwind of vulnerable ecosystems in the Himalaya mountains. They are also fragmented across 5 countries between which movement of people, data, instruments and scientific understanding have been very limited. ICIMOD's Atmosphere Initiative has for the past three years been working on filling data gaps in the region, while facilitating collaborations across borders. It has established several atmospheric observatories at low and mid elevations in Bhutan and Nepal that provide new data on the inflow of pollutants from the IGP towards the mountains, as well as quantify the effects of local emissions on air quality in mountain cities. EGU will be the first international conference where these data will be presented. ICIMOD is in the process of setting up data servers through which data from the region will be shared with scientists and the general public across borders. Meanwhile, to promote cross-border collaboration among scientists in the region, while addressing an atmospheric phenomenon that affects the lives of the several hundred million people, ICIMOD' Atmosphere Initiative has been coordinating an interdisciplinary multi-year study of persistent winter fog over the Indo-Gangetic Plains, with participation by researchers from Pakistan, India, China, Nepal, Bhutan and Bangladesh. Using a combination of in-situ measurements and sample collection, remote sensing, modeling and community based research, the researchers are studying how changing moisture availability and air pollution have led to increases in fog frequency and duration, as well as the fog's impacts on local communities and energy demand that may affect air pollution emissions. Preliminary results of the Winter 2015-2016 field campaign will be shown.

    Reproductive health research and policies in Cambodia focus on safe motherhood programs particularly for married women, ignoring comprehensive fertility regulation programs for unmarried migrant women of reproductive age. Maternal mortality risks arising due to unsafe abortion methods practiced by unmarried Cambodian women, across the Thai-Cambodia border, can be considered as a public health emergency. Since Thailand has restrictive abortion laws, Cambodian migrant women who have irregular migration status in Thailand experimented with unsafe abortion methods that allowed them to terminate their pregnancies surreptitiously. Unmarried migrant women choose abortion as a preferred birth control method seeking repeat "unsafe" abortions instead of preventing conception. Drawing on the data collected through surveys, in-depth interviews, and document analysis in Chup Commune (pseudonym), Phnom Penh, and Bangkok, the authors describe the public health dimensions of maternal mortality risks faced by unmarried Cambodian migrant women due to various unsafe abortion methods employed as birth control methods.

    With the accomplishment of its technical maturation, VoIP has been more rapidly developed and spread. However, some difficulties and problems also arise unavoidably and the problem, how VoIP applications traverse NAT or Firewall is one of them. VOCAL is an open-source code program that provides a SIP-based VOIP communication. Therefore, NAT traversal problem must be resolved when developing VoIP services with VOCAL. This thesis analyzes the issues brought by NAT in VoIP services and discusses the main solutions for traversing NAT. And then a solution over the VOCAL system named SBC is brought forward, which can do without changing any the present device. A SBC is located at the border of VOCAL system.

    2016-04-01

    A study was undertaken along the Kenya-Uganda border in four districts of Tororo and Busia (Uganda) and Busia and Teso (Kenya) to understand smallholder farmers' knowledge, practices and awareness of biosecurity measures. Information was collected by administering questionnaires to 645 randomly selected pig households in the study area. In addition, focus group discussions were carried out in 12 villages involving 248 people using a standardized list of questions. The outcome suggested that there was a very low level of awareness of biosecurity practices amongst smallholder farmers. We conclude that adoption of specific biosecurity practices by smallholder farmers is feasible but requires institutional support. There is a clear requirement for government authorities to sensitize farmers using approaches that allow active participation of farmers in the design, planning and implementation of biosecurity practices to enable enhanced adoption.

    2012-01-01

    Effectiveness of providing health education solely via mass media and the providers' targeted training in malaria control needs further exploration. During pre-epidemic season, we conducted a qualitative study of 40 providers and community leaders using focus groups, comprehensive semi-structured interviews and consultation observations. Interviews were transcribed, coded and analysed for major themes. Community leaders believe that they can acquire malaria from contaminated water, animal products, air or garbage. Consequently, they under-utilise bed nets and other protective measures due to perceived continued exposure to other potential malaria sources. Practitioners do not provide individualised health counselling and risk assessment to patients during sick visits, leading to a range of misconceptions about malaria based on limited knowledge from rumours and mass media, and a strong belief in the curative power of traditional medicine. Providers overdiagnose malaria clinically and underutilise available tests due to time constraints, and the lack of training and resources to correctly diagnose other illnesses. Subsequently, misdiagnoses lead them to question the efficacy of recommended treatments. Promoting counselling during clinical encounters to address patient misconception and change risky behaviour is warranted. Wider-ranging ongoing training could enable providers to properly diagnose and manage differential diagnoses to manage malaria better.

    In 1997, the Centers for Disease Control and Prevention, the Mexican Secretariat of Health, and border health officials began the development of the Border Infectious Disease Surveillance (BIDS) project, a surveillance system for infectious diseases along the U.S.-Mexico border. During a 3-year period, a binational team implemented an active, sentinel surveillance system for hepatitis and febrile exanthems at 13 clinical sites. The network developed surveillance protocols, trained nine surveillance coordinators, established serologic testing at four Mexican border laboratories, and created agreements for data sharing and notification of selected diseases and outbreaks. BIDS facilitated investigations of dengue fever in Texas-Tamaulipas and measles in California–Baja California. BIDS demonstrates that a binational effort with local, state, and federal participation can create a regional surveillance system that crosses an international border. Reducing administrative, infrastructure, and political barriers to cross-border public health collaboration will enhance the effectiveness of disease prevention projects such as BIDS. PMID:12533288

  3. Frequency Control Performance Measurement and Requirements

    Energy Technology Data Exchange (ETDEWEB)

    Illian, Howard F.

    2010-12-20

    Frequency control is an essential requirement of reliable electric power system operations. Determination of frequency control depends on frequency measurement and the practices based on these measurements that dictate acceptable frequency management. This report chronicles the evolution of these measurements and practices. As technology progresses from analog to digital for calculation, communication, and control, the technical basis for frequency control measurement and practices to determine acceptable performance continues to improve. Before the introduction of digital computing, practices were determined largely by prior experience. In anticipation of mandatory reliability rules, practices evolved from a focus primarily on commercial and equity issues to an increased focus on reliability. This evolution is expected to continue and place increased requirements for more precise measurements and a stronger scientific basis for future frequency management practices in support of reliability.

    2014-08-01

    This paper analyses the potential gains and the main challenges for increased cross-border collaboration in the control of highly contagious livestock diseases in regions with cross-border reliance on production and consumption of livestock commodities. The aim of this intensification of cross-border collaboration is to retain the economic advantages of cross-border trade in livestock and livestock commodities while maintaining a low risk of highly contagious livestock diseases. From these two foci, possibilities for future policy making with respect to highly contagious livestock diseases are discussed: peacetime cross-border cooperation to improve the cost-effectiveness of routine veterinary measures and crisis time cross-border harmonization of current disease control strategies. A general disease management framework was used to describe the way in which these two fields are related to and affect the epidemiological system and, consequently, how they impact the stakeholders. In addition to this framework, the importance of a good understanding of influencing factors, that is, the production structure of livestock, was stressed because these factors are important determinants of the frequency and magnitude of highly contagious livestock diseases and their economic impact. The use of the suggested integrated approach was illustrated for the extended cross-border region of the Netherlands and Germany, that is, North Rhine Westphalia and Lower Saxony. For this region, current difficulties in cross-border trade in livestock and livestock commodities and possibilities for future cross-border collaboration were examined. The concepts and ideas presented in this paper should foster future development of cross-border collaboration in animal health control. PMID:23066698

    Roots of many plants are known to produce large numbers of 'border' cells that play a central role in root protection and the interaction of the root with the rhizosphere. Unlike border cells, border-like cells were described only recently in the model plant Arabidopsis thaliana and other Brassicaceae species and very little is known about the functional properties of border-like cells as compared with 'classical' border cells. To stimulate discussion and future research on this topic, the function of border cells and the way border-like cells are organized, maintained, and possibly involved in plant protection is discussed here.

    This document is an analysis of options for unilateral and cooperative action to improve the security of Jordan's borders. Sections describe the current political, economic, and social interactions along Jordan's borders. Next, the document discusses border security strategy for cooperation among neighboring countries and the adoption of confidence-building measures. A practical cooperative monitoring system would consist of hardware for early warning, command and control, communications, and transportation. Technical solutions can expand opportunities for the detection and identification of intruders. Sensors (such as seismic, break-wire, pressure-sensing, etc.) can warn border security forces of intrusion and contribute to the identification of the intrusion and help formulate the response. This document describes conceptual options for cooperation, offering three scenarios that relate to three hypothetical levels (low, medium, and high) of cooperation. Potential cooperative efforts under a low cooperation scenario could include information exchanges on military equipment and schedules to prevent misunderstandings and the establishment of protocols for handling emergency situations or unusual circumstances. Measures under a medium cooperation scenario could include establishing joint monitoring groups for better communications, with hot lines and scheduled meetings. The high cooperation scenario describes coordinated responses, joint border patrols, and sharing border intrusion information. Finally, the document lists recommendations for organizational, technical, and operational initiatives that could be applicable to the current situation.

    Pulses to steer the time evolution of quantum systems can be designed with optimal control theory. In most cases it is the coherent processes that can be controlled and one optimizes the time evolution toward a target unitary process, sometimes also in the presence of noncontrollable incoherent processes. Here we show how to extend the gradient ascent pulse engineering (GRAPE) algorithm in the case where the incoherent processes are controllable and the target time evolution is a nonunitary quantum channel. We perform a gradient search on a fidelity measure based on Choi matrices. We illustrate our algorithm by optimizing a phase qubit measurement pulse. We show how this technique can lead to a large measurement contrast close to 99 % . We also show, within the validity of our model, that this algorithm can produce short 1.4 -ns pulses with 98.2 % contrast.

    Full Text Available This systematic review elaborates the concepts and impacts of border malaria, particularly on the emergence and spread of Plasmodium falciparum and Plasmodium vivax multidrug resistance (MDR malaria on Thailand-Myanmar and Thailand-Cambodia borders. Border malaria encompasses any complex epidemiological settings of forest-related and forest fringe-related malaria, both regularly occurring in certain transmission areas and manifesting a trend of increased incidence in transmission prone areas along these borders, as the result of interconnections of human settlements and movement activities, cross-border population migrations, ecological changes, vector population dynamics, and multidrug resistance. For regional and global perspectives, this review analyzes and synthesizes the rationales pertaining to transmission dynamics and the vulnerabilities of border malaria that constrain surveillance and control of the world’s most MDR falciparum and vivax malaria on these chaotic borders.

    Full Text Available In this paper the border is evaluated as a fold of power relations in which sovereign capacity and competence is marshaled in the furtherance of illiberal practices. Drawing from interview data of officials in various agencies engaged in the US-Canada and particularly the Windsor-Detroit corridor, the argument is made that the border is a site for both negative and positive power, for insertion and subtraction, and that surveillance and compliance regimes are ‘run’ not so much in the furtherance of a precautionary or preemptive end-state, but as intermediate values that are sufficiently malleable by an invigorated sovereign, expressed in the residue of discretion in and between the many border agencies.

    The objective of this paper is to show how a formal approach to networks can make a significant contribution to the study of cross-border trade in West Africa. Building on the formal tools and theories developed by Social Network Analysis, we examine the network organization of 136 large traders...... and cooperation shared among local traders, and on the distant ties developed with foreign partners from a different origin, religion or culture. Studying the spatial structure of trade networks, we find that in those markets where trade is recent and where most of the traders are not native of the region......, national borders are likely to exert a greater influence than in those regions where trade has pre-colonial roots. Combining formal network analysis and ethnographic studies, we argue, can make a significant contribution to the current revival of interest in cross-border trade in the policy field....

    1973-01-01

    A fluidic Turbine Inlet Gas Temperature (TIGIT) Measurement and Control System was developed for use on a Pratt and Whitney Aircraft J58 engine. Based on engine operating requirements, criteria for high temperature materials selection, system design, and system performance were established. To minimize development and operational risk, the TIGT control system was designed to interface with an existing Exhaust Gas Temperature (EGT) Trim System and thereby modulate steady-state fuel flow to maintain a desired TIGT level. Extensive component and system testing was conducted including heated (2300F) vibration tests for the fluidic sensor and gas sampling probe, temperature and vibration tests on the system electronics, burner rig testing of the TIGT measurement system, and in excess of 100 hours of system testing on a J58 engine.

    International Nuclear Information System (INIS)

    of Understanding (MOU) (1998) to promote co-operation at the international level in order to improve the control of radioactive materials. At the time of the drafting of this report, a similar MOU between the IAEA and the International Criminal Police Organization (INTERPOL) is pending. There are a number of measures that must be undertaken by States to combat the illicit trafficking and inadvertent movements of radioactive materials. These measures are, generally, shared between the regulatory and law enforcement agencies as part of a State's national arrangements. One of these measures id the subject of this TECDOC, namely detection of radioactive materials at borders. While effective detection involves many components of regulatory and law enforcement strategies, the major focus of this publication is on radiation detection and in particular, the instrumentation necessary for such purposes. Its intent is to assist Member State organizations in effectively detecting radioactive materials crossing their borders, whether importations, exportations, or shipments in transit. The purpose of this publication is to provide guidance for Member States for use by customs, police or other law enforcement bodies on the radiation monitoring of vehicles, people and commodities at border crossing facilities as a countermeasure to illicit trafficking and also to find inadvertent movement of radioactive materials. Such monitoring may be one component of efforts towards finding radioactive materials that have been lost from control and which may enter a Member State

    Previous studies in the border-effect literature surprisingly found that domestic border effects are larger than international border effects (e.g., in the United States or Brazil). One interpretation of this result is that these estimates include the effects of producer agglomeration. Therefore, in this study, we estimate those border effects exclusively for transactions for final consumption, in which such agglomeration forces will be weak, in China and Japan. As a result, we found larger i...

This follows a trend of border fence construction across Eurasia during the post-9/11 era. This development has gone largely unnoticed by conservation biologists during an era in which, ironically, transboundary cooperation has emerged as a conservation paradigm. These fences represent a major threat to wildlife because they can cause mortality, obstruct access to seasonally important resources, and reduce effective population size.

    Assessing the sustainability of International policy or urban development requires consideration of the impacts of these decisions on Ecosystem Services, or the values that humans receive from the ecosystem, including market-land price, environmental, and human well-being values. Hedonic modeling helps to identify the market land price, considering the price is determined by multiple factors affecting it. In U.S. portions of the bi-national Santa Cruz Watershed (SCW), situated at the Arizona-Sonora International border, natural amenities like the riparian corridor and green space have been documented as positive amenities that boost local real estate.

  19. Best available control measures for prescribed burning

    International Nuclear Information System (INIS)

    Section 190 of the Clean Air Act (CAA) as amended in 1990 requires the US Environmental Protection Agency (EPA) to issue guidance on Best Available Control Measures (BACM) of PM10 (particulate matter with a nominal aerodynamic diameter less than or equal to 10 micrometers) from urban fugitive dust, residential wood combustion, and prescribed silvicultural and agricultural burning (prescribed burning). The purpose of this guidance is to assist states (especially, but not exclusively, those with PM10 nonattainment areas which have been classified as serious) in developing a control measure for these three source categories. This guidance is to be issued no later than May 15, 1992 as required under the CAA. The guidance will be issued in the form of a policy guidance generic to all three BACM and in the form of Technical Information Documents (TIDs) for each of the three source categories. The policy guidance will provide the analytical approach for determining BACM and the TID will provide the technical information. The purpose of this paper is to present some insight from the forthcoming TID on what BACM might entail for prescribed burning in a serious PM10 nonattainment area

    2016-02-01

    The cross-border region of the Netherlands (NL) and the two German states of North Rhine Westphalia (NRW) and Lower Saxony (LS) is a large and highly integrated livestock production area. This region increasingly develops towards a single epidemiological area in which disease introduction is a shared veterinary and, consequently, economic risk. The objectives of this study were to examine classical swine fever (CSF) control strategies' veterinary and direct economic impacts for NL, NRW and LS given the current production structure and to analyse CSF's cross-border causes and impacts within the NL-NRW-LS region. The course of the epidemic was simulated by the use of InterSpread Plus, whereas economic analysis was restricted to calculating disease control costs and costs directly resulting from the control measures applied. Three veterinary control strategies were considered: a strategy based on the minimum EU requirements, a vaccination and a depopulation strategy based on NL and GER's contingency plans. Regardless of the veterinary control strategy, simulated outbreak sizes and durations for 2010 were much smaller than those simulated previously, using data from over 10 years ago. For example, worst-case outbreaks (50th percentile) in NL resulted in 30-40 infected farms and lasted for two to four and a half months; associated direct costs and direct consequential costs ranged from €24.7 to 28.6 million and €11.7 to 26.7 million, respectively. Both vaccination and depopulation strategies were efficient in controlling outbreaks, especially large outbreaks, whereas the EU minimum strategy was especially deficient in controlling worst-case outbreaks. Both vaccination and depopulation strategies resulted in low direct costs and direct consequential costs. The probability of cross-border disease spread was relatively low, and cross-border spread resulted in small, short outbreaks in neighbouring countries. Few opportunities for further cross-border harmonization and

    2007-01-01

    Plant roots release a large number of border cells into the rhizosphere, which are believed to play a key role in root development and health. The formation and loss of these cells from the root cap region is a developmentally regulated process that is also controlled by phytohormones and environmental factors. The separation of border cells involves the complete dissociation of individual cells from each other and from root tissue. This process requires the activity of cell wall-degrading enzymes that solubilize the cell wall connections between cells. We present and discuss the solubilization process with an emphasis on pectin-degrading enzymes as well as the recently discovered root border-like cells of Arabidopsis thaliana.

    The author demonstrates the Border Trade Facilitation System (BTFS), an agent-based bilingual e-commerce system built to expedite the regulation, control, and execution of commercial trans-border shipments during the delivery phase. The system was built to serve maquila industries at the US/Mexican border. The BTFS uses foundation technology developed here at Sandia Laboratories' Advanced Information Systems Lab (AISL), including a distributed object substrate, a general-purpose agent development framework, dynamically generated agent-human interaction via the World-Wide Web, and a collaborative agent architecture. This technology is also the substrate for the Multi-Agent Simulation Management System (MASMAS) proposed for demonstration at this conference. The BTFS executes authenticated transactions among agents performing open trading over the Internet. With the BTFS in place, one could conduct secure international transactions from any site with an Internet connection and a web browser. The BTFS is currently being evaluated for commercialization.

    Copenhagen and Cacun meetings failed to reach an agreement on post-2012 global emissions reduction mechanism, however, developed economies have proposed a policy proposal on climate change and energy, including implementing unilateral trade measures. The paper evaluates how Chinese exports are vulnerable to potential border carbon adjustments based on the assessment of cost increases from the application of carbon price of $20/t CO2 equivalent or $50/t CO2 equivalent, and clearly shows that there are many uncertainties in how border carbon adjustment might be designed. The application of carbon price, the methodology of assessing the carbon content of goods, and the design detail of schemes are key factors for the vulnerability of Chinese exports to potential border carbon adjustment measures.%虽然2012年后全球温室气体减排机制尚未达成,但各国纷纷制定气候和能源法案以促进减排。为维持国内企业竞争力,防止碳泄露和能源密集型产业转移.部分国家可能会实施单边贸易措施。文章主要结合美国相关法案,作出合理政策假设,利用IPCC氧化碳排放计算方法和投入产出模型,考察潜在碳边界调节措施对中国出口影响。结果发现.中国整体出口受碳成本上升影响有限,但基本钢铁产业、化学制造产业和非矿物制造产业的出口产品受冲击较大。

    2005-09-01

    One of the basic requirements for a scientific use of rain data from raingauges, ground and space radars is data quality control. Rain data could be used more intensively in many fields of activity (meteorology, hydrology, etc.), if the achievable data quality could be improved. This depends on the available data quality delivered by the measuring devices and the data quality enhancement procedures. To get an overview of the existing algorithms a literature review and literature pool have been produced. The diverse algorithms have been evaluated to meet VOLTAIRE objectives and sorted in different groups. To test the chosen algorithms an algorithm pool has been established, where the software is collected. A large part of this work presented here is implemented in the scope of the EU-project VOLTAIRE ( Validati on of mu ltisensors precipit ation fields and numerical modeling in Mediter ran ean test sites).

  7. Editorial: Human rights at the border

    2013-09-01

    Full Text Available t is with great honour that I introduce the second issue of the Anti-Trafficking Review (ATR. The first issue received an overwhelming response and has placed the journal at the forefront of rigorous analysis and debate relating to human trafficking and human rights. It raised the topic of accountability in anti-trafficking. This issue hopes to further strengthen the ATR’s position as a global, reputable journal on human trafficking. Strengthening the quality of research, analysis, and reflexivity in the trafficking sector is much needed, and I echo Anne Gallagher’s observation as guest editor of the first issue that standards in anti-trafficking research tend to be less rigorous than in other fields of study. My aim as a guest editor is to contribute to addressing this shortfall by bringing together a set of diverse and insightful articles focussing on the nexus of borders and human rights. It is also my hope that this issue will work towards narrowing the divide between practitioners and academics in anti-trafficking. This is reflected in the varied range of contributors. The last few years have witnessed a significant increase in publishing relating to human trafficking worldwide. However, there is limited measured debate and appraisal of this literature within the anti-trafficking sector. For this reason we have decided to include a book review as a way of highlighting recent major publications. The question of borders, migration control, trafficking and human rights raise contested and controversial questions. The editorial team has attempted to include different perspectives, reflected in the debate section in particular. Needless to say, all papers have been subject to double blind peer review.

  8. Extracellular Trapping of Soil Contaminants by Root Border Cells: New Insights into Plant Defense

    Directory of Open Access Journals (Sweden)

    Martha C. Hawes

    2016-01-01

    Full Text Available Soil and water pollution by metals and other toxic chemicals is difficult to measure and control, and, as such, presents an ongoing global threat to sustainable agriculture and human health. Efforts to remove contaminants by plant-mediated pathways, or “phytoremediation”, though widely studied, have failed to yield consistent, predictable removal of biological and chemical contaminants. Emerging research has revealed that one major limitation to using plants to clean up the environment is that plants are programmed to protect themselves: Like white blood cells in animals, border cells released from plant root tips carry out an extracellular trapping process to neutralize threats and prevent injury to the host. Variability in border cell trapping has been found to be correlated with variation in sensitivity of roots to aluminum, and removal of border cell results in increased Al uptake into the root tip. Studies now have implicated border cells in responses of diverse plant roots to a range of heavy metals, including arsenic, copper, cadmium, lead, mercury, iron, and zinc. A better understanding of border cell extracellular traps and their role in preventing toxin uptake may facilitate efforts to use plants as a nondestructive approach to neutralize environmental threats.

  9. Using Community Indicators to Assess Nutrition in Arizona-Mexico Border Communities

    Directory of Open Access Journals (Sweden)

    Jacob Abarca, PharmD

    2005-01-01

    Full Text Available Introduction Community indicators are used to measure and monitor factors that affect the well-being of a community or region. Community indicators can be used to assess nutrition. Evaluating nutrition in communities along the Arizona-Mexico border is important because nutrition is related to an individual’s risk of overweight or obesity; obesity is a risk factor for developing type 2 diabetes. Methods Local grocery store purchases were selected as a community indicator for nutrition. A structured 26-question interview was developed and administered to grocery store managers in communities along the Arizona-Mexico border that were targeted by the Border Health Strategic Initiative, a program implemented by community groups and the University of Arizona. In addition, data from milk distributors serving the border communities were collected. Results Residents of these communities favor food items with a higher fat and higher caloric content. This trend held across several food categories. Major barriers to customer acceptance of healthier food items include lack of knowledge concerning healthy foods and their prices. Conclusion The demand for healthy food items is relatively low along the Arizona-Mexico border. Interventions should continue to target this population with the aim of changing dietary patterns as one method of improving the health of the community and preventing and controlling diabetes.

  10. On the reconstruction of conductivity of bordered two-dimensional surface in R^3 from electrical currents measurements on its boundary

    CERN Document Server

    Henkin, Gennadi

    2010-01-01

    An electrical potential U on bordered surface X (in Euclidien three-dimensional space) with isotropic conductivity function sigma>0 satisfies equation d(sigma d^cU)=0, where d^c is real operator associated with complex (conforme) structure on X induced by Euclidien metric of three-dimensional space. This paper gives exact reconstruction of conductivity function sigma on X from Dirichlet-to-Neumann mapping (for aforementioned conductivity equation) on the boundary of X. This paper extends to the case of the Riemann surfaces the reconstruction schemes of R.Novikov (1988) and of A.Bukhgeim (2008) given for the case of domains in two-dimensional Euclidien space. The paper extends and corrects the statements of Henkin-Michel (2008), where the inverse boundary value problem on the Riemann surfaces was firstly considered.

    @@ Cardiovascular disease takes place in a border-free world. The challenge at the American College of Cardiology (ACC) and anywhere else in the world is to hold patient care above the artificial barriers raised by geopolitical issues. Fundamentally, the goal of ACC members or of any cardiology societies in the world is to provide excellent patient care. Cardiovascular disease is essentially the same throughout the world. Where there are minor variations among individuals, as clinicians we find priceless opportunity to learn. Expanding- rather contracting -our experience base helps us as individuals to realize our best potential as practitioners.

  12. GEOCHEMICAL CONTROLS ON NUCLEAR MAGNETIC RESONANCE MEASUREMENTS

    International Nuclear Information System (INIS)

    Proton nuclear magnetic resonance (NMR) is used in the Earth Sciences as a means of obtaining information about the molecular-scale environment of fluids in porous geological materials. Laboratory experiments were conducted to advance our fundamental understanding of the link between the NMR response and the geochemical properties of geological materials. In the first part of this research project, we studied the impact of both the surface-area-to-volume ratio (S/V) of the pore space and the surface relaxivity on the NMR response of fluids in sand-clay mixtures. This study highlighted the way in which these two parameters control our ability to use NMR measurements to detect and quantify fluid saturation in multiphase saturated systems. The second part of the project was designed to explore the way in which the mineralogic form of iron, as opposed to simply the concentration of iron, affects the surface relaxation rate and, more generally, the NMR response of porous materials. We found that the magnitude of the surface relaxation rate was different for the various iron-oxide minerals because of changes in both the surface-area-to-volume ratio of the pore space, and the surface relaxivity. Of particular significance from this study was the finding of an anomalously large surface relaxivity of magnetite compared to that of the other iron minerals. Differences in the NMR response of iron minerals were seen in column experiments during the reaction of ferrihydrite-coated quartz sand with aqueous Fe(II) solutions to form goethite, lepidocrocite and magnetite; indicating the potential use of NMR as a means of monitoring geochemical reactions. The final part of the research project investigated the impact of heterogeneity, at the pore-scale, on the NMR response. This work highlighted the way in which the geochemistry, by controlling the surface relaxivity, has a significant impact on the link between NMR data and the microgeometry of the pore space.

    Full Text Available Abstract Background Some island nations have explicit components of their influenza pandemic plans for providing travel warnings and restricting incoming travellers. But the potential value of such restrictions has not been quantified. Methods We developed a probabilistic model and used parameters from a published model (i.e., InfluSim and travel data from Pacific Island Countries and Territories (PICTs. Results The results indicate that of the 17 PICTs with travel data, only six would be likely to escape a major pandemic with a viral strain of relatively low contagiousness (i.e., for R0 = 1.5 even when imposing very tight travel volume reductions of 99% throughout the course of the pandemic. For a more contagious viral strain (R0 = 2.25 only five PICTs would have a probability of over 50% to escape. The total number of travellers during the pandemic must not exceed 115 (for R0 = 3.0 or 380 (for R0 = 1.5 if a PICT aims to keep the probability of pandemic arrival below 50%. Conclusion These results suggest that relatively few island nations could successfully rely on intensive travel volume restrictions alone to avoid the arrival of pandemic influenza (or subsequent waves. Therefore most island nations may need to plan for multiple additional interventions (e.g., screening and quarantine to raise the probability of remaining pandemic free or achieving substantial delay in pandemic arrival.

  14. Fine coal measurement needs for improved control

    The monitoring and management of fine coal circuits in coal preparation plants is limited in current practice. As part of the Australian Coal Association Research Program (ACARP) Intelligent Plant Project (C11069), the relationships between the main operational and control factors for the unit operations and the circuit and the performance indicators have been identified. The unit operations examined included desliming (hydrocyclones and sieve bends), small coal cleaning (spirals and hydraulic separators), flotation, and dewatering (vacuum filters, centrifuges, and thickeners). These relationships were then used to assist in the identification of the important parameters to be measured and the preferred level of accuracy required to be useful. An important issue was the interconnection between the various unit operations and the potential impact of an upstream problem on the subsequent performance of downstream units. Analysis with the relationships showed that the flow rate of respective feed slurries and the solids content were found to be significant variables. This article will discuss this analysis and provide some case studies.

    2016-08-01

    New viral respiratory pathogens are emerging with increasing frequency and have potentially devastating impacts on the population worldwide. Recent examples of newly emerged threats include severe acute respiratory syndrome coronavirus, the 2009 H1N1 influenza pandemic, and Middle East respiratory syndrome coronavirus. Experiences with these pathogens have shown up major deficiencies in how we deal globally with emerging pathogens and taught us salient lessons in what needs to be addressed for future pandemics. This article reviews the lessons learnt from past experience and current knowledge on the range of measures required to limit the impact of emerging respiratory infections from public health responses down to individual patient management. Key areas of interest are surveillance programs, political limitations on our ability to respond quickly enough to emerging threats, media management, public information dissemination, infection control, prophylaxis, and individual patient management. Respiratory physicians have a crucial role to play in many of these areas and need to be aware of how to respond as new viral pathogens emerge. PMID:27486741

    Recent scholarship suggests a significant association between cross-border ties, or ties maintained with family and friends in countries and communities of origin, and the mental health of immigrants and their descendants. To date, this research has been exclusively cross-sectional, precluding conclusions about a causal association between cross-border ties and mental health outcomes. In the present study we undertake a longitudinal analysis of the relationship between cross-border ties and depression measured over a ten-year period for a sample of immigrant and U.S.-born Latinos. Data are from the Sacramento Area Latino Study on Aging (1998-2008), a population-based, prospective study of Latin American-origin adults 60 years and older. We find that cross-border ties reported at baseline were significantly associated with depression in subsequent study waves, even after controlling for the presence of depression at baseline, albeit with substantial differences by gender and nativity. Specifically, communication with family and friends in Latin America and travel to Latin America at baseline were each significantly associated with greater odds of depression for immigrant women, but with lower odds of depression for U.S.-born Latina women over the study period. Travel to Latin America at baseline was significantly associated with lower odds of depression for Latino men across the study. Across all models we control for depressive symptomatology at baseline to account for the reciprocal nature of depressive symptoms and engagement with social ties, including cross-border ties. Our findings suggest that cross-border ties may represent a unique source of both resilience and risk for the long-term mental health of immigrant Latinos and their descendants. PMID:27239901

  4. Border mythology: Turner and modernity

    2011-07-01

    Full Text Available Modernity has been creating spaces, new boundaries and borders, as metaphysical, mythological and symbolic marks of physical and imaginary territories. Modern space and its borders are metaphors, boundaries that are created, walls that rise to identify with some and categorize others. In this short paper we want to approach the problem of the transformation of the idea of border (geographical, cultural, symbolic, etc., for a reflection on the transformations of that civilized obsession called border. The border has always been a reference in facing the identities, names, symbols, different imaginary: it is more confrontational line between two otherness. From the previous framework, we reflect on Turnerian mythology, as we believe that behind the creation of the imagination of the northern border is the mythical vision of the American frontier as ideological canon that explains and confirms the presence of the white race in a border re–made in the image and likeness of the “American Dream”. Frederick Turner’s reflection on the role of the frontier in American history is not only the study of the importance of progress towards the West but –even more so, is the analysis of meaning that had the American frontier as a historical process that ended in 1893, as Turner said, but rather extended into the twentieth century and continues to constantly shaping the process of territorialization of the border.

    Jacinto Choza Armenta

    2008-09-01

    Full Text Available During the different ages of history and prehistory, borders have possessed different kinds of natures. Sometimes they did not exist, at other times they have been very diffuse, while at others they have been impassable. There were no borders in the Paleolithic age, or during Greece’s Heroic Age. It was not until the creation of the city-states and the empires that borders began to be consolidated. Territorial demarcations were not very strict during the Middle Ages, either. It was in the modern age that borders acquired an impassable nature, following the birth of the modern State, and they began to weaken with the crisis of the modern State that began in the 20th century. Thus, the author claims, the construction of borders is not a fundamentally political-administrative event. Instead, it seems to be primarily a phenomenon of a cultural nature and, more specifically, of a metaphysical nature.

    Golz, Claudia; Einfalt, Thomas; Michaelides, Silas Chr.

    The basic condition for using precipitation data from raingauges and radars is data quality control. This aspect is important for comparing and using rainfall data, for example in models. In the scope of the EU-project VOLTAIRE (Validation of multisensors precipitation fields and numerical modelling in Mediterranean test sites) rain data from Cyprus have been analysed. Different quality control methods have been applied to the rainfall data of 158 raingauges and the data of 11 events (in 2002 and 2003) of the C-Band radar in Kykkos. The first results of the use of ground clutter algorithms for radar data in Cyprus are presented in the paper.

    Full Text Available The precision and programmability of robotic manipulators makes them suitable for biomechanics research, particularly when an experimental procedure must be accurately repeated multiple times. This paper describes a robotic system used to investigate biomechanical mechanisms of stroke in humans. A parallel robot manipulator is used to reproduce chiropractic manipulations on animal subjects using a 3-D vision system. An algorithm for calibrating the system is proposed and tested on the robot. An iterative learning control scheme is then introduced to improve positional accuracy. Experimental results demonstrate that the calibration procedure and learning scheme are both effective.

  2. Cross-Border Cholera Outbreaks in Sub-Saharan Africa, the Mystery behind the Silent Illness: What Needs to Be Done?

    Godfrey Bwire

    Full Text Available Cross-border cholera outbreaks are a major public health problem in Sub-Saharan Africa contributing to the high annual reported cholera cases and deaths. These outbreaks affect all categories of people and are challenging to prevent and control. This article describes lessons learnt during the cross-border cholera outbreak control in Eastern and Southern Africa sub-regions using the case of Uganda-DRC and Malawi-Mozambique borders and makes recommendations for future outbreak prevention and control.We reviewed weekly surveillance data, outbreak response reports and documented experiences on the management of the most recent cross-border cholera outbreaks in Eastern and Southern Africa sub-regions, namely in Uganda and Malawi respectively. Uganda-Democratic Republic of Congo and Malawi-Mozambique borders were selected because the countries sharing these borders reported high cholera disease burden to WHO.A total of 603 cross-border cholera cases with 5 deaths were recorded in Malawi and Uganda in 2015. Uganda recorded 118 cases with 2 deaths and CFR of 1.7%. The under-fives and school going children were the most affected age groups contributing 24.2% and 36.4% of all patients seen along Malawi-Mozambique and Uganda-DRC borders, respectively. These outbreaks lasted for over 3 months and spread to new areas leading to 60 cases with 3 deaths, CRF of 5%, and 102 cases 0 deaths in Malawi and Uganda, respectively. Factors contributing to these outbreaks were: poor sanitation and hygiene, use of contaminated water, floods and rampant cross-border movements. The outbreak control efforts mainly involved unilateral measures implemented by only one of the affected countries.Cross-border cholera outbreaks contribute to the high annual reported cholera burden in Sub-Saharan Africa yet they remain silent, marginalized and poorly identified by cholera actors (governments and international agencies. The under-fives and the school going children were the most

    2010-04-01

    We describe the public health control measures implemented in Singapore to limit the spread of influenza A (H1N1-2009) and mitigate its social effects. We also discuss the key learning points from this experience. Singapore's public health control measures were broadly divided into 2 phases: containment and mitigation. Containment strategies included the triage of febrile patients at frontline healthcare settings, admission and isolation of confirmed cases, mandatory Quarantine Orders (QO) for close contacts, and temperature screening at border entry points. After sustained community transmission became established, containment shifted to mitigation. Hospitals only admitted H1N1-2009 cases based on clinical indications, not for isolation. Mild cases were managed in the community. Contact tracing and QOs tapered off, and border temperature screening ended. The 5 key lessons learnt were: (1) Be prepared, but retain flexibility in implementing control measures; (2) Surveillance, good scientific information and operational research can increase a system's ability to manage risk during a public health crisis; (3) Integrated systems-level responses are essential for a coherent public health response; (4) Effective handling of manpower surges requires creative strategies; and (5) Communication must be strategic, timely, concise and clear. Singapore's effective response to the H1N1-2009 pandemic, founded on experience in managing the 2003 SARS epidemic, was a whole-of-government approach towards pandemic preparedness planning. Documenting the measures taken and lessons learnt provides a learning opportunity for both doctors and policy makers, and can help fortify Singapore's ability to respond to future major disease outbreaks.

    In this paper the notion of border will be examined in a cultural life course perspective. I will investigate borders as psycho-cultural constructions created to enable and control meaning-making in the intersection between subjects engagements and concerns and collectively constructed and guiding meanings. An empirical analysis of one boy's life course in and between home, school and a Leisure Time Activity Center in the years 1st to 3rd grade demonstrates a systemic construction of borders involving him, his teachers and his parents and renders the boy to choose between becoming an engaged pupil or a dedicated son. As such, the analysis can illuminate processes of school - home interactions that work opposite of what is intended and become detrimental to children's life. In a cultural life course perspective borders show how life is maintained as meaningful and not only guide the present living but also serve as directional guides into the future. PMID:26205071

    Koya, Yoshiharu; Nagahara, Yoshihiro

    The arteriosclerosis is on the increase with an aging or change of our living environment. For that reason, diagnosis of the common carotid artery using echocardiogram is doing to take precautions carebropathy. The arteriosclerosis of the common carotid artery is diagnosed using Intima-Media Thickness (IMT) which is obtained from echocardiogram. In order to measure IMT from echocardiogram, it is required to detect a border which is a boundary between vessel tissue layers. The method of border detection requires reproducibility and high accuracy. The conventional methods to detect the border curve depend on differential value of brightness on the common carotid artery. Therefore, we can't extract a good candidate point by influence of a noise. In this paper, we propose the high-accuracy detection method by Hough Transform. About high-accuracy, it realized by attaching importance to high reliable candidate point of border.

  10. Over the border--the problems of uncontrolled radioactive materials crossing national borders.

    Science.gov (United States)

    Duftschmid, K E

    2002-03-01

    Cross-border movement of radioactive materials and contaminated items, in particular metallurgical scrap, has become a problem of increasing importance. Radioactive sources out of regulatory control, now often called 'orphan sources', have frequently caused serious, even deadly, radiation exposures and widespread contamination. The United States Nuclear Regulatory Commission reported over 2,300 incidents of radioactive materials found in recycled metal scrap and more than 50 accidental smeltings of radioactive sources. A further potentially serious problem is illicit trafficking in nuclear and other radioactive materials. In 1995 the International Atomic Energy Agency (IAEA) started a programme to combat illicit trafficking in nuclear and other radioactive materials, which includes an international database on incidents of illicit trafficking, receiving reports from some 80 member states. For the period 1993-2000 the IAEA database includes 345 confirmed incidents. While from 1994-1996 the frequency declined significantly, this trend has been reversed since 1997, largely due to radioactive sources rather than nuclear material. This paper compares monitoring techniques for radioactive materials in scrap applied at steel plants and scrap yards with monitoring at borders, a completely different situation. It discusses the results of the 'Illicit Trafficking Radiation Detection Assessment Program', a large international pilot study, conducted in cooperation between the IAEA, the Austrian Government and the Austrian Research Centre Seibersdorf. The aim of this exercise was to derive realistic and internationally agreed requirements for border monitoring instrumentation. Finally the present extent of border monitoring installations is discussed. PMID:11929111

    Each nation's laws should prohibit development, acquisition, or transfer of WMD-critical items and should make it a crime to violate that prohibition for hostile purposes. Thus, WMD proliferation should be illegal everywhere, powerfully reinforcing the norm against acquisition of such weapons as well as facilitating law enforcement and trans-national legal cooperation. Provisions applicable to threats should be harmonized. National laws should address threats and should ensure prosecution of offenders or extradition to another State for prosecution. The scope of legal jurisdiction over such crimes should broadly reach the behaviour of legal entities in trans-national smuggling and weapons development conspiracies. A priority question is precisely which activity should constitute a criminal offence. It is relatively straightforward to make the use of WMD a crime; but it will be necessary to reach preparatory steps that can encompass innocent behaviour or even legitimate scientific inquiry. Bio-terror preparations, for example, may employ the same materials, equipment and techniques as undertaking legitimate disease research. Standards must be developed to instruct law enforcers as to what behaviour merits criminal investigation to prevent a hostile attack. Similarly, legal measures must define 'WMD' items, including chemical and biological agents that are non-lethal but incapacitating to humans as well as agents that are lethal as to animal or plant life. If WMD proliferation is criminalized, each State's law enforcement officials must work jointly with their counterparts in other States by sharing information, conducting investigations, and prosecuting apprehended terrorists. State cooperation both in gathering intelligence and using that information to prevent criminal activity is undermined, however, by lack of coherent legal instruments. Currently, there is no integrated database of State laws concerning production or use of WMD; it is difficult to know what

  17. Cross-border ties and Arab American mental health.

    Due to increasing discrimination and marginalization, Arab Americans are at a greater risk for mental health disorders. Social networks that include ties to the country of origin could help promote mental well-being in the face of discrimination. The role of countries of origin in immigrant mental health receives little attention compared to adjustment in destination contexts. This study addresses this gap by analyzing the relationship between nativity, cross-border ties, and psychological distress and happiness for Arab Americans living in the greater Detroit Metropolitan Area (N = 896). I expect that first generation Arab Americans will have more psychological distress compared to one and half, second, and third generations, and Arab Americans with more cross-border ties will have less psychological distress and more happiness. Data come from the 2003 Detroit Arab American Study, which includes measures of nativity, cross-border ties--attitudes, social ties, media consumption, and community organizations, and the Kessler-10 scale of psychological distress and self-reported happiness. Ordered logistic regression analyses suggest that psychological distress and happiness do not vary much by nativity alone. However, cross-border ties have both adverse and protective effects on psychological distress and happiness. For all generations of Arab Americans, cross-border attitudes and social ties are associated with greater odds of psychological distress and for first generation Arab Americans, media consumption is associated with greater odds of unhappiness. In contrast, for all generations, involvement in cross-border community organizations is associated with less psychological distress and for the third generation, positive cross-border attitudes are associated with higher odds of happiness. These findings show the complex relationship between cross-border ties and psychological distress and happiness for different generations of Arab Americans. PMID:26999416

    The article deals with the evolution of the concept of borders between human groups and with its slow evolution from the initial no men's land zones to the ideal single-dimension linear borders. In ancient times the first borders were natural, such as mountain ranges or large rivers until, with the development of Geodesy, astronomical borders based on meridians and parallels became a favourite natural base. Actually, Modern States adopted these to fix limits in unknown conquered territories. The postmodern thought led give more importance to cultural borders until, in the most recent times, is becoming rather impossible to fix borders in the virtual cyberspace.

  2. Dynamics of immigration control.

    Djajic, S

    1999-01-01

    This paper examines the dynamic implications of US border control policies and internal enforcement measures for the pattern of illegal immigration and the sectoral allocation of clandestine foreign workers. Efforts to counteract illegal immigration into the US have been increasing steadily following the passage of the Immigration Reform and Control Act of 1986. The purpose of the Act is to reduce illegal immigration with the aid of three instruments: 1) employer sanctions; 2) increased controls along the border; and 3) a legalization program designed to meet the existing demand for agricultural labor in geographic locations that are in proximity of Mexico, the principal source of clandestine foreign labor. The effect of tougher border control measures increases the cost of illegal entry, discouraging clandestine inflows. On the other hand, these measures induce migrants to increase their own anti-detection efforts, reducing the probability of detection and the deportation rate. If the latter effect should dominate, the steady-state stock of clandestine foreign labor will actually increase in response to more vigorous border control measures. Explicit consideration of the role of networks in the clandestine labor market suggests the need for a drastic policy change. This policy change should target illegal migration in areas with high concentrations of clandestine foreign workers. Complementary measures should accompany this policy change to prevent unbalanced enforcement measures.

    2004-07-01

    The consumption of electricity by maquiladora industries in the Mexican border states is an important driver for determining future powerplant needs in that area. An industrial electricity forecasting model is developed for the border states' maquiladoras, and the outputs are compared with a reference forecasting model developed for the US industrial sector, for which considerably more data are available. This model enables the prediction of the effect of implementing various energy efficiency measures in the industrial sector. As an illustration, here the impact of implementing energy-efficient lighting and motors in the Mexican border states' maquiladoras was determined to be substantial. Without such energy efficiency measures, electricity consumption for these industries is predicted to rise by 64% from 2001 to 2010, but if these measures are implemented on a gradual basis over the same time period, electricity consumption is forecast to rise by only 36%.

  14. Measurements of Control Rod Worths in Critical and Exponential Assemblies

    International Nuclear Information System (INIS)

    Control rods of cadmium, stainless steel and a Cd -In -A g alloy have been investigated by means of three different methods: (a) Measurements of buckling differences and migration areas in a zero-power reactor (R0); (b ) Pulsed subcritical measurements in RO with a compact neutron pulse generator; and (c ) Buckling measurements in an exponential assembly (ZEBRA). The measurements were made in different lattices of natural uranium metal rods and heavy water. Radial and axial statistical weights for one and two control rods were measured by means of method (a) with an accuracy in ΔB2 of 0.005 m-2. The upper limit in the value of ΔB2 is about -1.5 m-2, equivalent to -4% of reactivity. The accuracy in the pulsed measurements is of the order of 5%, but in this case it is possible to measure very large negative reactivities. In the exponential assembly we have tried to separate the thermal and epithermal absorption effects by measuring the control-rod worths with only moderator in the tank as well as in different reactor lattices. The accuracy was of the same order as in the critical measurements. (author)

    2008-10-01

    Full Text Available Abstract Background Malaria control in remote, forested areas of the Mekong region relies on personal protection from mosquito bites. Uptake of these methods may be limited by knowledge of the link between mosquitoes and malaria as well as social and economic aspects. Understanding barriers to uptake will inform malaria control programmes on targets for improvement of delivery. Methods A total 748 key respondents: health providers and village heads, from 187 villages and 25 different ethnic groups, were interviewed using structured questionnaires. Differences in use of personal protection, and knowledge of malaria between groups were analysed using chi-square; and binary logistic regression used for multivariate analysis. Results Malaria knowledge was poor with 19.4% of women and 37.5% of men linking mosquitoes with malaria, although 95.6% knew one or more methods of mosquito control. Virtually all respondents used personal protection at some time during the year; and understanding of malaria transmission was strongly associated with bednet use. Those working in forest agriculture were significantly more likely to know that mosquitoes transmit malaria but this did not translate into a significantly greater likelihood of using bednets. Furthermore, use of personal protection while woing outdoors was rare, and less than 3% of respondents knew about the insecticide impregnation of bednets. The use of bednets, synthetic repellents and mosquito coils varied between ethnic groups, but was significantly more frequent among those with higher income, more years of education and permanent housing. The reported use of repellents and coils was also more common among women despite their low knowledge of malaria transmission, and low likelihood of having heard information on malaria within the last year. Conclusion The use of personal protection must be increased, particularly among outdoor workers that have higher malaria risk. However, personal protection

    1994-01-01

    New capabilities for hydrologic property measurements in triaxial systems include: (1) volume-controlled and simultaneous measurements of hydraulic conductivity and one-dimensional consolidation (or specific storage) of a saturated test specimen; and (2) volume-controlled measurements of hydraulic conductivity, matric potential, and the variation of these properties with the moisture content of an unsaturated test specimen. Data on saturated kaolinite demonstrate simultaneous hydraulic-conductivity and one-dimensional consolidation tests with continuous monitoring of both vertical and horizontal effective stresses. Data on well-graded silty sand demonstrate the feasibility of concurrent constant-flow hydraulic conductivity and mattic potential measurements, and the variation of these properties with moisture content, for undisturbed and unsaturated specimens mounted in triaxial cells. Refinements needed to realize the full potential of these capabilities include a more rigid triaxial cell to minimize compliance, and an improved technique for measuring hydraulic-head differences within an unsaturated test specimen.

  7. Old Borders and New Bordering Capabilities: Cities as Frontier Zones

    Directory of Open Access Journals (Sweden)

    Saskia Sassen

    2015-12-01

    Full Text Available The global city is a new frontier zone. Deregulation, privatization, and new fiscal and monetary policies create the formal instruments to construct their equivalent of the old military “fort”. The city is also a strategic frontier zone for those who lack power, and allows the making of informal politics. At the same time the border is a mix of regimes, marked by protections and opportunities for corporations and high-level professionals, and implies confinement, capture and detention for migrants. The essay discusses the transformation of the city in a frontier zone and analyses the separation between the capabilities entailed by territoriality and the geographic territory tout court. The analysis focuses on the effects of neoliberal policies that, far from making this a borderless world, have actually multiplied the bordered spaces that allow firms and markets to move across conventional borders. Cities are therefore one of the key sites where new neoliberal norms are made and where new identities emerge.

    Objective To propose a dynamic hunting extremum control method based on comparison of the estimated value and measured value. Methods The output linear group of the system is approximately expressed as an nth-order system with large time constant or with time delay. Moreover, the relation between input drive reversal of the logic circuit and dynamic output of the system is analyzed in detail. The calculating formulae for the drive reversal are given for different extremum control systems. Based on principles above, a controller using a micrprocessor and a testing laboratory plant were designed and implemented. Results With this new method, the controller achieves fast optimum point hunting process, good performance in extremum control systems for high order processes, and robust result under sudden change or drift of the extremum characteristics. Conclusion The new control owns the merits of rapid optimizing dynamics, robusticity, and wide applicability.

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    A new concept called intelligent virtual control (IVC), which can be driven by measuring functions, is put forward. This small "intelligent measurement instrument unit (IMIU)", carrying with functions of instrument, consists of different types of intelligent virtual instrument (IVI) through individual components together as building blocks and can be displayed directly on the computer screen. This is a new concept of measuring instrument, and also an important breakthrough after virtual instrument (VI). Virtual control makes instrument resources obtain further exploitation. It brings about a fundamental change to the design and manufacturing mode. The instrument therefore, can not only be produced directly inside a PC, but the product is involved in the "green product" system. So far, all the present digital instruments will grow to be replaced by intelligent control with green characteristics.

    Vaeliviita, S.; Ovaska, S.J. [Helsinki University of Technology, Otaniemi (Finland). Institute of Intelligent Power Electronics

    1997-12-31

    Delayless and accurate sensing of angular acceleration can improve the performance of motion control in motor drives. Acceleration control is, however, seldom implemented in practical drive systems due to prohibitively high costs or unsatisfactory results of most acceleration measurement methods. In this paper we propose an efficient and accurate acceleration measurement method based on direct differentiation of the corresponding velocity signal. Polynomial predictive filtering is used to smooth the resulting noisy signal without delay. This type of prediction is justified by noticing that a low-degree polynomial can usually be fitted into the primary acceleration curve. No additional hardware is required to implement the procedure if the velocity signal is already available. The performance of the acceleration measurement method is evaluated by applying it to a demanding motion control application. (orig.) 12 refs.

    Full Text Available In this work, we address the problem of global attitude control using direct inertial measurements. When using direct inertial measurement to observe the rigid body attitude, it is shown that due to a geometrical obstruction, it is impossible to achieve global asymptotic stability. In fact, for a particular initial condition the tracking error quaternion converges to a pure imaginary quaternion formed by an eigenvector of a characteristic matrix related to the inertial constant and known vectors. Our proposition consists of adding a dynamic signal to force the rigid body to escape from such a situation. The proposed observer-based controller is synthesized based on a single Lyapunov function and a stability analysis shows that the controller stabilizes globally and asymptotically the rigid body attitude at the desired one. The effectiveness of the proposed observer-based controller is confirmed by simulation results.

  14. Revitalising Borders: Memory, Mobility and Materiality in a Latvian-Russian Border Region

    2016-01-01

    In this paper I investigate how an international border is 'revitalised' in political discourses as opposed to lived experiences. Based on narratives I have collected from border dwellers on both sides of the current border between Latvia and Rus-sia and placing them into a broader context of current border debates, I analyse how geographical and social mobility is remembered from Soviet times and reworked in current contexts. I argue that while politically the border is revitalised through a...

    2015-01-01

    Full Text Available European borders, or borders between European Union member states, are historical products that embody the ebbs and flows of European borderlands. These areas are evolving from past struggles and confrontations between European kingdoms toward a future of progressive European integration. Such processes are highly complex, as they involve border deactivation. In this work, we examine the evolution of the Spanish- Portuguese border from the perspective of cross-border interaction.

  18. Individual pitch control of wind turbines using local inflow measurements

    DEFF Research Database (Denmark)

    Thomsen, Sven Creutz; Niemann, Hans Henrik; Poulsen, Niels Kjølstad

    2008-01-01

    This paper describes a model based control approach for individually adjusting the pitch of wind turbine blades and thereby attenuating the effect of asymmetric wind loads. It is assumed that measurements of local inflow along each blade are available. This effectively provides an estimate of the...... load distribution along the blades. The load estimates are used in a predictive setup where inflow measured by one blade is used as basis for calculating future loads for the other blades. Simulations with a full stochastic wind field illustrate the effectiveness of the individual pitch controller as...

  1. Quantum Control nd Measurement of Spins in Cold Atomic Gases

    Science.gov (United States)

    Deutsch, Ivan

    2014-03-01

    Spins are natural carriers of quantum information given their long coherence time and our ability to precisely control and measure them with magneto-optical fields. Spins in cold atomic gases provide a pristine environment for such quantum control and measurement, and thus this system can act as a test-bed for the development of quantum simulators. I will discuss the progress my group has made in collaboration with Prof. Jessen, University of Arizona, to develop the toolbox for this test-bed. Through its interactions with rf and microwave magnetic fields, whose waveforms are designed through optimal control techniques, we can implement arbitrary unitary control on the internal hyperfine spins of cesium atoms, a 16 dimensional Hilbert space (isomorphic to 4 qubits). Control of the collective spin of the ensemble of many atoms is performed via the mutual coupling of the atomic ensemble to a mode of the electromagnetic field that acts as a quantum data bus for entangling atoms with one another. Internal spin control can be used to enhance the entangling power of the atom-photon interface. Finally, both projective and weak-continuous measurements can be performed to tomograhically reconstruct quantum states and processes.

    Full Text Available A two-dimensional sagittally symmetric human-body model was established to simulate an optimal trajectory for manual material handling tasks. Nonlinear control techniques and genetic algorithms were utilized in the optimizations to explore optimal lifting patterns. The simulation results were then compared with the experimental data. Since the kinetic measures such as joint reactions and moments are vital parameters in injury determination, the importance of comparing kinetic measures rather than kinematical ones was emphasized.

    2015-01-01

    The purpose of this review is to synthesize the current knowledge on the international movement of patients and biopsied embryo cells for pre-implantation genetic diagnosis and its different applications. Thus far, few attempts have been made to identify the specific nature of this phenomenon called 'cross-border reprogenetic services'. There is scattered evidence, both empirical and speculative, suggesting that these services raise major issues in terms of service provision, risks for patients and the children-to-come, the legal liabilities of physicians, as well as social justice. To compile this evidence, this review uses the narrative overview protocol combined with thematic analysis. Five major themes have emerged from the literature at the conjunction of cross-border treatments and reprogenetics: 'scope', 'scale', 'motivations', 'concerns', and 'governance'. Similar themes have already been observed in the case of other medical tourism activities, but this review highlights their singularity with reprogenetic services. It emphasizes the diagnostic and autologous feature of reprogenetics, the constant risk of misdiagnosis, the restriction on certain tests for medically controversial conditions, and the uncertain accessibility of genetic counseling in cross-border settings.

  7. Measures for product control during the treatment of radioactive waste

    International Nuclear Information System (INIS)

    Process control during conditioning of the wastes can be used as a very appropriate measure to perform the task of quality assurance. This contribution aims to outline what such a process control would look like in practice. A number of examples is examined dealing with wastes typically arising during the operation of nuclear power plants and during MOX fuel fabrication. The examples also cover treatment by the waste generator or a hired service company, with stationary or mobile facilities. It is found that the system of process control as introduced by the paper could be adopted for all examples. (orig./PW)

  8. Transmission potential of chikungunya virus and control measures: the case of Italy.

    Directory of Open Access Journals (Sweden)

    Piero Poletti

    Full Text Available During summer 2007 Italy has experienced an epidemic caused by Chikungunya virus - the first large outbreak documented in a temperate climate country - with approximately 161 laboratory confirmed cases concentrated in two bordering villages in North-Eastern Italy comprising 3,968 inhabitants. The seroprevalence was recently estimated to be 10.2%. In this work we provide estimates of the transmission potential of the virus and we assess the efficacy of the measures undertaken by public health authorities to control the epidemic spread. To such aim, we developed a model describing the temporal dynamics of the competent vector, known as Aedes albopictus, explicitly depending on climatic factors, coupled to an epidemic transmission model describing the spread of the epidemic in both humans and mosquitoes. The cumulative number of notified cases predicted by the model was 185 on average (95% CI 117-278, in good agreement with observed data. The probability of observing a major outbreak after the introduction of an infective human case was estimated to be in the range of 32%-76%. We found that the basic reproduction number was in the range of 1.8-6 but it could have been even larger, depending on the density of mosquitoes, which in turn depends on seasonal meteorological effects, besides other local abiotic factors. These results confirm the increasing risk of tropical vector-borne diseases in temperate climate countries, as a consequence of globalization. However, our results show that an epidemic can be controlled by performing a timely intervention, even if the transmission potential of Chikungunya virus is sensibly high.

    Root border cells separate from plant root tips and disperse into the soil environment. In most species, each root tip can produce thousands of metabolically active cells daily, with specialized patterns of gene expression. Their function has been an enduring mystery. Recent studies suggest that border cells operate in a manner similar to mammalian neutrophils: Both cell types export a complex of extracellular DNA (exDNA) and antimicrobial proteins that neutralize threats by trapping pathogens and thereby preventing invasion of host tissues. Extracellular DNases (exDNases) of pathogens promote virulence and systemic spread of the microbes. In plants, adding DNase I to root tips eliminates border cell extracellular traps and abolishes root tip resistance to infection. Mutation of genes encoding exDNase activity in plant-pathogenic bacteria (Ralstonia solanacearum) and fungi (Cochliobolus heterostrophus) results in reduced virulence. The study of exDNase activities in plant pathogens may yield new targets for disease control. PMID:27215971

    2000-03-01

    The survival of a plant depends upon the capacity of root tips to sense and move towards water and other nutrients in the soil. Perhaps because of the root tip's vital role in plant health, it is ensheathed by large populations of detached somatic cells - root 'border' cells - which have the ability to engineer the chemical and physical properties of the external environment. Of particular significance, is the production by border cells of specific chemicals that can dramatically alter the behavior of populations of soilborne microflora. Molecular approaches are being used to identify and manipulate the expression of plant genes that control the production and the specialized properties of border cells in transgenic plants. Such plants can be used to test the hypothesis that these unusual cells act as a phalanx of biological 'goalies', which neutralize dangers to newly generated root tissue as the root tip makes its way through soil.

    Full Text Available IntroductionThe diabetes hospitalization rate for the region along the U.S. side of the U.S.–Mexico border is unknown, a situation that could limit the success of the Healthy Border 2010 program. To remedy this problem, we analyzed and compared hospital discharge data for Arizona, California, and Texas for the year 2000 and calculated the diabetes hospitalization rates.MethodsWe obtained hospital-discharge public-use data files from the health departments of three U.S. border states and looked for cases of diabetes. Only when diabetes was listed as the first diagnosis on the discharge record was it considered a case of diabetes for our study. Patients with cases of diabetes were classified as border county (BC or nonborder county (NBC residents. Comparisons between age-adjusted diabetes discharge rates were made using the z test.ResultsOverall, 1.2% (86,198 of the discharge records had diabetes listed as the primary diagnosis. BC residents had a significantly higher age-adjusted diabetes discharge rate than NBC residents. BC males had higher diabetes discharge rates than BC females or NBC males. In both the BCs and the NBCs, Hispanics had higher age-adjusted diabetes discharge rates than non-Hispanics.ConclusionThe results of this study provide a benchmark against which the effectiveness of the Healthy Border 2010 program can be measured.

  15. Radio-controlled boat for measuring water velocities and bathymetry

    Vidmar, Andrej; Bezak, Nejc; Sečnik, Matej

    2016-04-01

    Radio-controlled boat named "Hi3" was designed and developed in order to facilitate water velocity and bathymetry measurements. The boat is equipped with the SonTek RiverSurveyor M9 instrument that is designed for measuring open channel hydraulics (discharge and bathymetry). Usually channel cross sections measurements are performed either from a bridge or from a vessel. However, these approaches have some limitations such as performing bathymetry measurements close to the hydropower plant turbine or downstream from a hydropower plant gate where bathymetry changes are often the most extreme. Therefore, the radio-controlled boat was designed, built and tested in order overcome these limitations. The boat is made from a surf board and two additional small balance support floats. Additional floats are used to improve stability in fast flowing and turbulent parts of rivers. The boat is powered by two electric motors, steering is achieved with changing the power applied to left and right motor. Furthermore, remotely controlled boat "Hi3" can be powered in two ways, either by a gasoline electric generator or by lithium batteries. Lithium batteries are lighter, quieter, but they operation time is shorter compared to an electrical generator. With the radio-controlled boat "Hi3" we can perform measurements in potentially dangerous areas such as under the lock gates at hydroelectric power plant or near the turbine outflow. Until today, the boat "Hi3" has driven more than 200 km in lakes and rivers, performing various water speed and bathymetry measurements. Moreover, in future development the boat "Hi3" will be upgraded in order to be able to perform measurements automatically. The future plans are to develop and implement the autopilot. With this approach the user will define the route that has to be driven by the boat and the boat will drive the pre-defined route automatically. This will be possible because of the very accurate differential GPS from the Sontek River

  2. Power-over-ethernet for remote measurement and control

    International Nuclear Information System (INIS)

    Power-Over-Ethernet (PoE) technology (IEEE standard 802.3af) allows Remote Measurement and Control in harsh environment where human access is difficult in various nuclear research fields. The terminal measurement and control unit receives power for its operation and communicates data over the same LAN cable, without needing to provide power supplies from different source. Almost all data acquisition systems require both data connectivity and a power supply. In a familiar example, telephones are powered from the telephone exchange through the same twisted pair that carries the voice. Now we can do the same thing with Ethernet devices by combining power and data. Only one set of wires is required to bring to the end measurement and control unit which will simplify installation and save space. Remote unit can be easily moved, to wherever a LAN cable can be laid with minimal disruption to the workplace. It is safer as no mains supply is required. Uninterrupted power supply can be guaranteed to the terminal unit during mains power failure. The terminal unit can be shut down and reset remotely without needing for a reset button and power switch. Simple Network Management Protocol (SNMP) can be used to monitor and control the remote unit. PoE will enable to deploy many more embedded systems in nuclear and other industry like Voice over Internet Protocol (VoIP), Security Camera, Tele-information System, Remote Access Control System, Intruder Detection System, and Tele-Medicine System, etc. (author)

    2015-12-01

    Full Text Available Common unique ETRS89 coordinates of the state boundaries are crucial for cross-border data harmonization for international projects. In the frame of European Location Framework (ELF project Czech Office for Surveying, Mapping and Cadastre (ČÚZK cooperates with Poland on egde-matching on the state border. During the preliminary phase of the project was some difficulty identified. If the state boundary is measured and administered in the national coordinate system, the accuracy of the transformation into the ETRS89 is influenced by discrepancies of the local trigonometric network, which results in two slightly different state boundaries. Final solution for Europe – international treaties on the state borders based on the ETRS89 coordinates – is necessary, but it will take years.

The reliability so expected can only be ensured by achieving the desired quality in construction. Quality mainly depends upon the effective controlling of materials used in construction, work procedures adopted, personnel performing the important functions and work environment and also ensuring proper documentation. The above fact has been well recognized during construction of the Project at Kalpakkam under Dept. of Atomic Energy. The control measures which have been designed and successfully implemented for achieving the quality are presented. (author)

  7. Buddhism on the Border: Shan Buddhism and Transborder Migration in Northern Thailand

    Directory of Open Access Journals (Sweden)

    Tadayoshi Murakami

    2012-08-01

    Full Text Available This paper examines the transformation of Shan Buddhism in the border area of Northern Thailand. Shan and other ethnic groups have a long history of migration between Northern Thailand and the Shan State of Myanmar; the migration continued even after the border was demarcated at the end of the nineteenth century. Recently, the migration has become unidirectional—from Myanmar to Thailand— and the number of migrants is growing steadily. An anomalous situation exists in this area: a fluid border crossing of people, goods, and information in spite of rigid border control by the Thai government. In the religious sphere, the Thai government has been institutionalizing and standardizing “Thai Buddhism” since the early twentieth century. The government’s efforts seem to have succeeded, resulting in the unified organization of “State Sangha” and a systematized curriculum for monastic education. In the process, local Sanghas (Buddhist monastic communities in the kingdom have been integrated into the State Sangha of Thailand. However, Shan Buddhism in the border area has not been totally assimilated into Thai Buddhism and maintains its unique seasonal festivals, religious rites of passage, practices using Shan manuscripts, and temple architecture. By focusing on the movement of people in the border area, where strong state control and a porous border coexist, this paper analyzes the important role of border migration in the continuation and development of Shan Buddhist practices in Northern Thailand.

  9. A capacitance servo control plunger for accurate lifetime measurement

    International Nuclear Information System (INIS)

    The recoil distance Doppler shift method has been widely used in the study of nuclear structure to determine the level lifetime and absolute transition probabilities. A capacitance servo control plunger based on this method has been successfully developed by the Nuclear Structure Group of the China Institute of Atomic Energy. Three microscopes were employed to check the parallelism and can therefore guarantee a delicate measurement of the distance between the target and the stopper. This new plunger made a successful performance in the test experiment and the measured lifetime of the 2+→0+ transition in 78Kr is in agreement with the previous value. (authors)

  11. Halon inerting as a hydrogen control measure for Sequoyah

    International Nuclear Information System (INIS)

    Halon inerting after accident initiation has been proposed as a hydrogen control measure for the Sequoyah nuclear plant containment building. A literature search was carried out and simple analyses were performed in order to assess the pros and cons of using Halon and to develop a design concept for an inerting system. The most significant problem associated with Halon use in a nuclear plant appears to be decomposition of the Halon into corrosive gases and liquids

  13. Prevalence of tabacco product use in Latvia and control measures

    2012-10-01

    Full Text Available The use of tobacco products is a major problem having a serious effect on public health. Deaths from external causes are those that can be prevented by ensuring environmental safety and educating the society about the effect of lifestyle habits and behaviour on health of an individual. Not only research data reveal the prevalence of tobacco use but also the rate of tobacco sales. Tobacco industry marketing includes advertising, sales promotion and sponsorship strategies that are aimed at promotion of tobacco use. Demand for tobacco products is influenced also by changes in legislation relating to ban on tobacco advertising and sponsorship. Therefore it is necessary to introduce an agreed strategy for reducing tobacco use. The countries that have ratified the World Health Organisation (WHO Framework Convention on Tobacco Control (the Convention should develop and implement an effective tobacco control programme. In Latvia the number of daily smokers gradually decreases thanks to the extensive smoking restrictions though tobacco manufacturers use all the available media, radio and television, newspapers, magazines, advertisements and Internet, to advertise their products. Therefore in order to combat the prevalence of smoking first of all it is necessary to limit cigarette marketing and sales and to carry out monitoring and development of tobacco control measures on the state level. The sales of legal cigarettes have decreased in Latvia starting from 2009. However, the increase in tax rates and prices has contributed to the movement of illegal goods therefore it is necessary to take additional restrictive measures concerning the movement of illegal goods. Though amendments to legislation of Latvia relating to tobacco control comply with the requirements of the WHO Convention it is necessary to evaluate the efficiency of control measures and to improve them. Systematic and comprehensive education of the public is required to encourage the change of

  17. Obtaining the borders of urban areas

    CERN Document Server

    Comin, Cesar Henrique; Costa, Luciano da Fontoura

    2015-01-01

    The access to an ever increasing amount of information in the modern world gave rise to the development of many quantitative indicators about urban regions in the globe. Therefore, there is a growing need for a precise definition of how to delimit urban regions, so as to allow proper respective characterization and modeling. Here we present a straightforward methodology to automatically detect urban region borders. The method is based on the density of street crossings around a single seed point associated to the urban area of interest. We exemplify the potential of the methodology by characterizing the geometry and topology of 21 urban regions obtained from 8 distinct countries. The geometry is studied by employing the lacunarity measurement, which is associated to the regularity of holes contained in a pattern. The topology is analyzed by associating the betweenness centrality of the streets with their respective class, such as motorway or residential, obtained from a database.

  20. Automatic control system for measuring currents produced by ionization chambers

    International Nuclear Information System (INIS)

    Ionization Chambers in current mode operation are usually used in Nuclear Metrology. Activity measurements are quickly performed by Ionization Chambers, with very good precision. For this purpose measurements of very low ionization currents, carried out by high quality instrumentation, are required. Usually, electrometers perform the current integration method under command of signals from an automation system, in order to reduce the measurement uncertainties. Among the measurement systems at the Laboratorio de Metrologia Nuclear (LMN) of IPEN, there are two ionization chamber systems. In the present work, an automation system developed for current integration measurements is described. This automation system is composed by software (graphic interface and control) and an electronic module connected to a microcomputer, by means of a commercial data acquisition card. Several test measurements were performed in order to determine the intrinsic uncertainty, linearity and stability of the system. Using calibrated radioactive solutions, the IG12/A20 chamber calibration factors for 18F and 153Sm were obtained, making possible to determine activities of these radionuclides. (author)

  1. Real-time control of sewer systems using turbidity measurements.

    Science.gov (United States)

    Lacour, C; Schütze, M

    2011-01-01

    Real-time control (RTC) of urban drainage systems has been proven useful as a means to reduce pollution by combined sewer overflow discharges. So far, RTC has been investigated mainly with a sole focus on water quantity aspects. However, as measurement techniques for pollution of wastewater are advancing, pollution-based RTC might be of increasing interest. For example, turbidity data sets from an extensive measurement programme in two Paris catchments allow a detailed investigation of the benefits of using pollution-based data for RTC. This paper exemplifies this, comparing pollution-based RTC with flow-based RTC. Results suggest that pollution-based RTC indeed has some potential, particularly when measurements of water-quality characteristics are readily available.

  2. The Borders of "Shopluk" and/or Shops without Borders

    Directory of Open Access Journals (Sweden)

    P. Hristov

    2015-08-01

    Full Text Available A historic and cultural region exists at the heart of the Balkans, known in geographic and ethnographic research as Shopluk. This is a region in which, over the last 150 years, state boundaries were moved several times as a result of 5 different wars. Today, the historic Shopluk is where the borders of three nations converge – Republic of Bulgaria, Republic of Serbia and the Republic of Macedonia – and, during the last decade, the region was declared one of the “Euroregions” on the Balkans. Despite the historical similarities in traditional culture and language of this population, in the 19th century it became a subject of nationalist ambitions and a propaganda “wars” between the new national states of Serbia and Bulgaria. The joining of Bulgarian-inhabited parts of Shopluk (the regions of today’s Dimitrovgrad and Bosilegrad in Serbia to the Kingdom of Serbs, Slovenes and Croats in 1919 created a long-lasting tension between the two countries, some residues of which can be felt in everyday relations even today. On the other hand, it has been a century-long tradition for men in this region to take part in seasonal labour migrations all over the Balkan Peninsula, despite political borders. In this way, preserving their cultural and lingual specifics, the groups of seasonal workers – migrants from Shopluk, became a bridge for cultural interaction and exchange with other regions in the neighbour countries. Even though today the population of Shopluk exhibits different national identities, historical similarities in culture and language can turn the Euroregion between Nish, Sofia and Skopje from one of the poorest on the Balkans to one of the most integrated and prosperous.

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available We analyze Test Driven Development (TDD from cognitive and social perspectives. Based on our analysis, we suggest a technique for controlling and monitoring the TDD process by examining measures that relate to the size and complexity of both code and tests. We call this approach Measured TDD. The motivation for TDD arose from practitioners' tendency to rush into code production, skipping the required testing needed to manufacture quality products. The motivation for Measured TDD is based on difficulties encountered by practitioners in applying TDD. Specifically, with the need to frequently refactor the unit, after every few test and code steps have been performed. We found that the suggested technique enables developers to gain better control over the development process.

  8. Alleviating Border Effects in Wavelet Transforms for Nonlinear Time-varying Signal Analysis

    Directory of Open Access Journals (Sweden)

    SU, H.

    2011-08-01

    Full Text Available Border effects are very common in many finite signals analysis and processing approaches using convolution operation. Alleviating the border effects that can occur in the processing of finite-length signals using wavelet transform is considered in this paper. Traditional methods for alleviating the border effects are suitable to compression or coding applications. We propose an algorithm based on Fourier series which is proved to be appropriate to the application of time-frequency analysis of nonlinear signals. Fourier series extension method preserves the time-varying characteristics of the signals. A modified signal duration expression for measuring the extent of border effects region is presented. The proposed algorithm is confirmed to be efficient to alleviate the border effects in comparison to the current methods through the numerical examples.

    Purpose: The purpose of this paper is to describe the food landscape of Texas using the CDC’s Modified Retail Food Environment (mRFEI) and to make comparisons by border/non-border. Methods: The Modified Retail Food Environment index (mRFEI (2008)) is an index developed by the CDC that measures what percent of the total food vendors in a census track sell healthy food. The range of values is 0 (unhealthy areas with limited access to fruits and vegetables) to (100—Healthy). These data were linked to 2010 US Census socioeconomic and ethnic concentration data. Spatial analysis and GIS techniques were applied to assess the differences between border and non-border regions. Variables of interest were mRFEI score, median income, total population, percent total population less than five years, median age, % receiving food stamps, % Hispanic, and % with a bachelor degree. Results: Findings from this study reveal that food environment in Texas tends to be characteristic of a “food desert”. Analysis also demonstrates differences by border/non-border location and percent of the population that is foreign born and by percent of families who receive food stamps. Conclusions: Identifying the relationship between socioeconomic disparity, ethnic concentration and mRFEI score could be a fundamental step in improving health in disadvantage communities, particularly those on the Texas-Mexico border.

    Full Text Available Lymphatic filariasis caused by Wuchereria bancrofti and Brugia malayi is an important public health problem in India. Both parasites produce essentially similar clinical presentations in man, related mainly to the pathology of the lymphatic system. Filariasis is endemic in 17 States and six Union Territories, with about 553 million people at risk of infection. The Government of India has accorded a high priority for elimination of this infection through mass chemotherapy programme (annual, single dose of Diethylcarbamazine citrate, i.e. DEC - 6 mg/kg of bodyweight, plus Albendazole repeated four to six times. This campaign has become a part of the National Vector-Borne Disease Control Programme in 2003 under the National Health Policy 2002 and aims to eliminate filariasis by 2015. We discuss here the epidemiology and current control strategy for filariasis; highlighting key issues, challenges and options in the implementation of the programme, and suggesting measures for mid-course corrections in the elimination strategy.

  13. Development of an integrated control and measurement system

    International Nuclear Information System (INIS)

    This thesis presents a tutorial on the issues involved in the development of a minicomputer-based, distributed intelligence data acquisition and process control system to support complex experimental facilities. The particular system discussed in this thesis is under development for the Atomic Vapor Laser Isotope Separation (AVLIS) Program at the Oak Ridge Gaseous Diffusion Plant (ORGDP). In the AVLIS program, we were careful to integrate the computer sections of the implementation into the instrumentation system rather than adding them as an appendage. We then addressed the reliability and availability of the system as a separate concern. Thus, our concept of an integrated control and measurement (ICAM) system forms the basis for this thesis. This thesis details the logic and philosophy that went into the development of this system and explains why the commercially available turn-key systems generally are not suitable. Also, the issues involved in the specification of the components for such an integrated system are emphasized

  14. An appraisal of measures to prevent and control psoriasis.

    Science.gov (United States)

    Farber, E M; Nall, L

    1984-03-01

    Prevention in a broad sense refers to limiting the progress of disease at any stage of its course; control refers to reduction in frequency and/or severity of a disease in a population. Measures to prevent and control psoriasis require a knowledge on behalf of both the physician and the patient to recognize genetic and environmental components in the onset and course of the disease. Triggering factors include streptococcal throat infection, injury, drugs, low humidity, and emotional stress. From a study of 102 severely affected psoriasis patients, the "Three-P Concept" for the management of psoriasis has evolved encompassing: (1) prevention of injury, (2) persistence in avoiding overtreatment, and (3) pauses or rest periods in the course of treatment with sedation, emolliation, and humidification. Educating psoriasis patients about their disease and encouraging them to take responsibility for self-care will lessen the morbidity.

  15. Measurements and simulation of controlled beamfront motion in the Laser Controlled Collective Accelerator

    Energy Technology Data Exchange (ETDEWEB)

    Yao, R.L.; Destler, W.W.; Striffler, C.D.; Rodgers, J.; Scgalov, Z.

    1989-01-01

    In the Laser Controlled Collective Accelerator, an intense electron beam is injected at a current above the vacuum space charge limit into an initially evacuated drift tube. A plasma channel, produced by time-sequenced, multiple laser beam ionization of a solid target on the drift tube wall, provides the necessary neutralization to allow for effective beam propagation. By controlling the rate of production of the plasma channel as a function of time down the drift tube, control of the electron beamfront can be achieved. Recent experimental measurements of controlled beamfront motion in this configuration are presented, along with results of ion acceleration experiments conducted using two different accelerating gradients. These results are compared with numerical simulations of the system in which both controlled beamfront motion and ion acceleration is observed consistent with both design expectations and experimental results. 5 refs., 6 figs.

    We present a novel technique to remotely measure and control the local temperature within a medium. This technique is based on the observation of the rotational Brownian motion of gold nanocrescent particles, which possess a strong anisotropic light interaction due to their plasmonic properties. Rotational scattering correlation spectroscopy performed on a single nanoparticle is able to determine the local temperature with high accuracy. These nano-thermometers can simultaneously play the role of nano-heaters when absorbing the light of a focused laser beam. (paper)

    Hannah M Edwards

    Full Text Available Human population movement across country borders presents a real challenge for malaria control and elimination efforts in Cambodia and its neighbouring countries. To quantify Plasmodium infection among the border-crossing population, including asymptomatic and artemisinin resistant (AR parasites, three official border crossing points, one from each of Cambodia's borders with Thailand, Laos and Vietnam, were selected for sampling.A total of 3206 participants (of 4110 approached were recruited as they crossed the border, tested for malaria and interviewed. By real-time polymerase chain reaction (RT-PCR, 5.4% of all screened individuals were found to harbour Plasmodium parasites. The proportion was highest at the Laos border (11.5%. Overall there were 97 P. vivax (55.7%, 55 P. falciparum (31.6%, two P. malariae (1.1% and 20 mixed infections (11.5%. Of identified infections, only 20% were febrile at the time of screening. Of the 24 P. falciparum samples where a further PCR was possible to assess AR, 15 (62.5% had mutations in the K13 propeller domain gene, all from participants at the Laos border point. Malaria rapid diagnostic test (RDT pLDH/HRP-2 identified a positivity rate of 3.2% overall and sensitivity compared to RT-PCR was very low (43.1%. Main individual risk factors for infection included sex, fever, being a forest-goer, poor knowledge of malaria prevention methods and previous malaria infection. Occupation, day of the week and time of crossing (morning vs. afternoon also appeared to play an important role in predicting positive cases.This study offers a novel approach to identify asymptomatic infections and monitor AR parasite flow among mobile and migrant populations crossing the borders. Similar screening activities are recommended to identify other hot borders and characterise potential hot spots of AR. Targeted "customised" interventions and surveillance activities should be implemented in these sites to accelerate elimination efforts

  1. In situ SO2 measurement for closed loop control

    International Nuclear Information System (INIS)

    This paper reports on EPA Compliance which is a large factor in the cost of producing steam. Much of this cost stems from maintenance of optical and/or extractive SO2 Monitors. Downstream from a wet scrubber, the optical or extractive monitor usually does not work. A newly developed in situ SO2 Probe that uses the solid electrolyte technique of measurement, provides an accurate, continuous, on line measurement of SO2 for Certification to EPA Performance Specifications and control of the SO2 removal system. Moreover, the system is justifiable on the basis of cost savings in operation and maintenance. The virtually maintenance free in situ SO2 Analyzer is similar to and used with the field proven in situ zirconium oxide SO2 Analyzer. The SO2 Probe uses a potassium sulfate electrochemical cell for the determination of stack gas SO2 levels

  2. Simultaneous Authentication and Certification of Arms-Control Measurement Systems

    International Nuclear Information System (INIS)

    Most arms-control-treaty-monitoring scenarios involve a host party that makes a declaration regarding its nuclear material or items and a monitoring party that verifies that declaration. A verification system developed for such a use needs to be trusted by both parties. The first concern, primarily from the host party's point of view, is that any sensitive information that is collected must be protected without interfering in the efficient operation of the facility being monitored. This concern is addressed in what can be termed a 'certification' process. The second concern, of particular interest to the monitoring party, is that it must be possible to confirm the veracity of both the measurement system and the data produced by this measurement system. The monitoring party addresses these issues during an 'authentication' process. Addressing either one of these concerns independently is relatively straightforward. However, it is more difficult to simultaneously satisfy host party certification concerns and monitoring party authentication concerns. Typically, both parties will want the final access to the measurement system. We will describe an alternative approach that allows both parties to gain confidence simultaneously. This approach starts with (1) joint development of the measurement system followed by (2) host certification of several copies of the system and (3) random selection by the inspecting party of one copy to be use during the monitoring visit and one (or more) copy(s) to be returned to the inspecting party's facilities for (4) further hardware authentication; any remaining copies are stored under joint seal for use as spares. Following this process, the parties will jointly (5) perform functional testing on the selected measurement system and then (6) use this system during the monitoring visit. Steps (1) and (2) assure the host party as to the certification of whichever system is eventually used in the monitoring visit. Steps (1), (3), (4), and (5

  4. A polyhedral approach to computing border bases

    CERN Document Server

    Braun, Gábor

    2009-01-01

    Border bases can be considered to be the natural extension of Gr\\"obner bases that have several advantages. Unfortunately, to date the classical border basis algorithm relies on (degree-compatible) term orderings and implicitly on reduced Gr\\"obner bases. We adapt the classical border basis algorithm to allow for calculating border bases for arbitrary degree-compatible order ideals, which is \\emph{independent} from term orderings. Moreover, the algorithm also supports calculating degree-compatible order ideals with \\emph{preference} on contained elements, even though finding a preferred order ideal is NP-hard. Effectively we retain degree-compatibility only to successively extend our computation degree-by-degree. The adaptation is based on our polyhedral characterization: order ideals that support a border basis correspond one-to-one to integral points of the order ideal polytope. This establishes a crucial connection between the ideal and the combinatorial structure of the associated factor spaces.

  5. Revitalising Borders: Memory, Mobility and Materiality in a Latvian-Russian Border Region

    Directory of Open Access Journals (Sweden)

    Aija Lulle

    2016-04-01

    Full Text Available In this paper I investigate how an international border is 'revitalised' in political discourses as opposed to lived experiences. Based on narratives I have collected from border dwellers on both sides of the current border between Latvia and Rus-sia and placing them into a broader context of current border debates, I analyse how geographical and social mobility is remembered from Soviet times and reworked in current contexts. I argue that while politically the border is revitalised through aban-doning and forgetting the Soviet past and through the idea of constant threats in the future, locally it is revitalised through giving a life to the abandoned: memories of 'vigorous times' in life-courses and material things. People who dwell at the border did not move themselves: the international border moved several times in one cen-tury leaving border dwellers' memories and significant places on the 'other' side. I focus on how these borders were crossed in the past, how they are (not crossed now, and the social meanings assigned to these circumstances. In the current con-text I follow diverse paths of reasoning that describe how the uneven flow of goods and people through the Latvian-Russian border shapes the power dynamic against which the people living in the border area used to reconstruct imaginaries of 'Soviet times' versus 'Europe' and 'vigorous times' versus decline.

    Plants dedicate a large amount of energy to the regulated production of living cells programmed to separate from roots into the external environment. This unusual process may be worth the cost because it enables the plant to dictate which species will share its ecological niche. For example, border cells can rapidly attract and stimulate growth in some microorganisms and repel and inhibit the growth of others. Such specificity may provide a way to control the dynamics of adjacent microbial populations in the soil to foster beneficial associations and inhibit pathogenic invasion. Plant genes controlling the delivery of border cells and the expression of their unique properties provide tools to genetically engineer plants with altered border cell quality and quantity. Such variants are being used to test the hypothesis that the function of border cells is to protect plant health by controlling the ecology of the root system.

  7. CROSS-BORDER COOPERATION AT THE EXTERNAL BORDERS OF EUROPEAN UNION

    Full Text Available To cooperate means to work and act together for a common advantage or purpose. The cooperation across borders, between different countries and regions sharing the same border, to reach common goals, is aimed to increase the overall competitiveness of the regional economy and to improve the quality of living standards for the these areas. European Union’s programmes are good accelerators for cross-border cooperation. The paper is focused on cross-border cooperation programmes at the external border of the EU and the expected impact of the allocated funds. The cross-border cooperation programmes are creating the conditions to exist the relationships between different social and economic stakeholders in order to contribute to economic and social development by supporting SME development, innovation, human resources development, civil society and local communities, increasing educational, social, cultural and sporting exchanges, improving local governance in different cross-border areas.

    In respiratory input impedance measurements, the low-frequency range contains important clinical and physiological information. However, the patient's spontaneous ventilation can contaminate the data in this range, leading to unreliable results. Unbiased estimators are a good alternative to overcome this problem, provided that the generator is considered linear. This condition is not fulfilled by most existing generators as they are based on loudspeakers, which have strong nonlinearities. The present work aims to contribute to the solution of this problem, and describes a pressure generator that minimises the nonlinearities by an optical sensor placed in a position feedback loop. The static evaluation shows a high linearity for the optical system. The well known frequency response of pressure transducers is used in the dynamic evaluation of the instrument. The analysis of the generator shows that the use of position feedback improved the frequency response. The total harmonic distortion (THD) measurement shows that closed loop resulted in an effective decrease in the nonlinearities. The reduction of THD achieved by the servo-controlled generator can contribute to the practical implementation of the unbiased estimators, increasing the reliability of the impedance data, especially in the low-frequency range. This system is compared with conventional generators and with another servo-controlled system.

    Purpose: Breast density is a significant breast cancer risk factor. Although various methods are used to estimate breast density, there is no standard measurement for this important factor. The authors are developing a breast density standardization method for use in full field digital mammography (FFDM). The approach calibrates for interpatient acquisition technique differences. The calibration produces a normalized breast density pixel value scale. The method relies on first generating a baseline (BL) calibration dataset, which required extensive phantom imaging. Standardizing prospective mammograms with calibration data generated in the past could introduce unanticipated error in the standardized output if the calibration dataset is no longer valid. Methods: Sample points from the BL calibration dataset were imaged approximately biweekly over an extended timeframe. These serial samples were used to evaluate the BL dataset reproducibility and quantify the serial calibration accuracy. The cumulative sum (Cusum) quality control method was used to evaluate the serial sampling. Results: There is considerable drift in the serial sample points from the BL calibration dataset that is x-ray beam dependent. Systematic deviation from the BL dataset caused significant calibration errors. This system drift was not captured with routine system quality control measures. Cusum analysis indicated that the drift is a sign of system wear and eventual x-ray tube failure. Conclusions: The BL calibration dataset must be monitored and periodically updated, when necessary, to account for sustained system variations to maintain the calibration accuracy.

    REX Control System is a professional advanced tool for design and implementation of complex control systems that belongs to softPLC category. It covers the entire process starting from simulation of functionality of the application before deployment, through implementation on real-time target, towards analysis, diagnostics and visualization. Basically it consists of two parts: the development tools and the runtime system. It is also compatible with Simulink environment, and the way of implementation of control algorithm is very similar. The control scheme is finally compiled (using RexDraw utility) and uploaded into a chosen real-time target (using RexView utility). There is a wide variety of hardware platforms and real-time operating systems supported by REX Control System such as for example Windows Embedded, Linux, Linux/Xenomai deployed on SBC, IPC, PAC, Raspberry Pi and others with many I/O interfaces. It is modern system designed both for measurement and control applications, offering a lot of additional functions concerning data archiving, visualization based on HTML5, and communication standards. The paper will sum up possibilities of its use in educational process, focused on control of case studies of physical models with classical and advanced control algorithms.

  11. Knowledge, Attitudes, and Practices among Border Crossers during Temporary Enforcement of a Formal Entry Requirement for Mexican-Style Soft Cheeses, 2009†

    Mexican-style soft cheese known as queso fresco (QF), which is often unpasteurized, has been implicated in outbreaks of foodborne illness in the United States. The U.S. Food and Drug Administration (FDA) exercises discretion in enforcement of noncommercial importation of cheese. To test control measures aimed at decreasing unlawful QF importation, in 2009 the FDA temporarily enforced a requirement for formal commercial entry for all cheeses over 5 lb (2.3 kg) at the San Diego–Tijuana border. Enforcement was combined with educational outreach. Border crossers importing cheese and those not importing cheese were surveyed at the beginning and end of the temporary enforcement period. Data collected included participant demographic information, knowledge of QF-associated health risks, and attitudes and practices regarding QF consumption and importation. We surveyed 306 importers and 381 nonimporters. Compared with nonimporters, importers had a lower level of knowledge regarding QF-associated health risks (P < 0.0001). Border crossers carrying cheese were more likely to have less education, be U.S. or dual residents, consume QF more frequently, and cross the border less often. Importation and consumption of unpasteurized QF remained prevalent among border crossers during the temporary enforcement period, and the level of knowledge regarding QF-associated risks remained low among these crossers. More vigorous, sustained messaging targeted at high-risk groups is needed to change behaviors. Definition and consistent enforcement of limits will likely be needed to reduce QF importation and the risk of QF-associated diseases along the U.S.–Mexico border; however, public health benefits will need to be balanced against the cost of enforcement.

  12. Evaluation of Intersection Traffic Control Measures through Simulation

    2015-12-01

    Modeling traffic flow is stochastic in nature due to randomness in variables such as vehicle arrivals and speeds. Due to this and due to complex vehicular interactions and their manoeuvres, it is extremely difficult to model the traffic flow through analytical methods. To study this type of complex traffic system and vehicle interactions, simulation is considered as an effective tool. Application of homogeneous traffic models to heterogeneous traffic may not be able to capture the complex manoeuvres and interactions in such flows. Hence, a microscopic simulation model for heterogeneous traffic is developed using object oriented concepts. This simulation model acts as a tool for evaluating various control measures at signalized intersections. The present study focuses on the evaluation of Right Turn Lane (RTL) and Channelised Left Turn Lane (CLTL). A sensitivity analysis was performed to evaluate RTL and CLTL by varying the approach volumes, turn proportions and turn lane lengths. RTL is found to be advantageous only up to certain approach volumes and right-turn proportions, beyond which it is counter-productive. CLTL is found to be advantageous for lower approach volumes for all turn proportions, signifying the benefits of CLTL. It is counter-productive for higher approach volume and lower turn proportions. This study pinpoints the break-even points for various scenarios. The developed simulation model can be used as an appropriate intersection lane control tool for enhancing the efficiency of flow at intersections. This model can also be employed for scenario analysis and can be valuable to field traffic engineers in implementing vehicle-type based and lane-based traffic control measures.

    Coal-fired electric power generation accounts for 65% of U.S. emissions of sulfur dioxide (SO2), 22% of nitrogen oxides (NOx), and 37% of mercury (Hg). The proposed Clear Air Interstate Rule (CAIR) and Clean Air Mercury Rule (CAMR) will attempt to regulate these emissions using a cap-and-trade program to replace a number of existing regulatory requirements that will impact this industry over the next decade. Mercury emissions remain the largest source that has not yet been efficiently controlled, in part because this is one of the most expensive to control. Mercury is a toxic, persistent pollutant that accumulates in the food chain. During the coal combustion process, when both sampling and accurate measurements are challenging, we know that mercury is present in three species: elemental, oxidized and particulate. There are three basic types of mercury measurement methods: Ontario Hydro Method, mercury continuous emission monitoring systems (CEMS) and sorbent-based monitoring. Particulate mercury is best captured by electrostatic precipitators (ESP). Oxidized mercury is best captured in wet scrubbers. Elemental mercury is the most difficult to capture, but selective catalytic reduction units (SCRs) are able to convert elemental mercury to oxidized mercury allowing it to be captured by wet flue gas desulfurization (FGD). This works well for eastern coals with high chlorine contents, but this does not work well on the Wyoming Powder River Basin (PRB) coals. However, no good explanation for its mechanism, correlations of chlorine content in coal with SCR performance, and impacts of higher chlorine content in coal on FGD re-emission are available. The combination of SCR and FGD affords more than an 80% reduction in mercury emissions in the case of high chlorine content coals. The mercury emission results from different coal ranks, boilers, and the air pollution control device (APCD) in power plant will be discussed. Based on this UAEPA new regulation, most power plants

    The acceleration of investigations in Speech Recognition allows to augur, in the next future, a wide establishment of Vocal Control Systems in the production units. The communication between a human and a machine necessitates technical devices that emit, or are submitted to important noise perturbations. The vocal interface introduces a new control problem of a deterministic automaton using uncertain information. The purpose is to place exactly the automaton in a final state, ordered by voice, from an unknown initial state. The whole Speech Processing procedure, presented in this paper, has for input the temporal speech signal of a word and for output a recognised word labelled with an intelligibility index given by the recognition quality. In the first part, we present the essential psychoacoustic concepts for the automatic calculation of the loudness of a speech signal. The architecture of a Time Delay Neural Network is presented in second part where we also give the results of the recognition. The theory of the fuzzy subset, in third part, allows to extract at the same time a recognised word and its intelligibility index. In the fourth part, an Anticipatory System models the control of a Sequential Machine. A prediction phase and an updating one appear which involve data coming from the information system. A Bayesian decision strategy is used and the criterion is a weighted sum of criteria defined from information, minimum path functions and speech intelligibility measure.

    2015-06-01

    Full Text Available The idea that the sovereignty of the nation-state has collapsed under the weight of globalization "and it is now an empty shell" has long been a conviction rooted in political and social sciences, which speak openly of an era of post-sovereignty. However, the sovereignty of the State finds an ultimate and indispensable bulwark in the defense and in the border control. But as things stand when sovereignty is «popular»? What principles the democratic state of law can appeal to practice an immigration policy which unilaterally terminate the company to strangers? The thesis proposed in the article argues that the democratic theory does not consider, in this regard, any discretionary. If «the people is an aspiration, not a fact», as Benhabib argues, the regime of border control, to be democratically legitimate, should take into account both the perspective of insiders, and that of the outsiders.

    This occasional paper identifies applicable cooperative monitoring techniques and develops models for possible application in the context of the border between China and India. The 1993 and 1996 Sino-Indian agreements on maintaining peace and tranquility along the Line of Actual Control (LAC) and establishing certain confidence building measures (CBMs), including force reductions and limitation on military exercises along their common border, are used to examine the application of technically based cooperative monitoring in both strengthening the existing terms of the agreements and also enhancing trust. The paper also aims to further the understanding of how and under what conditions technology-based tools can assist in implementing existing agreements on arms control and confidence building. The authors explore how cooperative monitoring techniques can facilitate effective implementation of arms control agreements and CBMS between states and contribute to greater security and stability in bilateral, regional, and global contexts.

    Clinical mobility assessment is traditionally performed in laboratories using complex and expensive equipment. The low accessibility to such equipment, combined with the emerging trend to assess mobility in a free-living environment, creates a need for body-worn sensors (e.g., inertial measurement units-IMUs) that are capable of measuring the complexity in motor performance using meaningful measurements, such as joint orientation. However, accuracy of joint orientation estimates using IMUs may be affected by environment, the joint tracked, type of motion performed and velocity. This study investigates a quality control (QC) process to assess the quality of orientation data based on features extracted from the raw inertial sensors' signals. Joint orientation (trunk, hip, knee, ankle) of twenty participants was acquired by an optical motion capture system and IMUs during a variety of tasks (sit, sit-to-stand transition, walking, turning) performed under varying conditions (speed, environment). An artificial neural network was used to classify good and bad sequences of joint orientation with a sensitivity and a specificity above 83%. This study confirms the possibility to perform QC on IMU joint orientation data based on raw signal features. This innovative QC approach may be of particular interest in a big data context, such as for remote-monitoring of patients' mobility. PMID:27399701

    In those laboratories involved in the measurement of radioactivity it is considered that a good determination requires, among other issues, and adequate monitoring of equipment performance and reagents and tracers. In this paper some of the parameters, of equipment performance are described together with some of the problems associated with their control and outlining possible solutions. Later, routine determinations are considered. For it is taken into account that an adequate control of the goodness of the results requires checking the whole measurement system, from sample reception to results delivery. In addition, the pros and cons of carrying out the enlargement of the control system so as to include management and performance of the laboratory as a whole in order to obtain an accreditation as external acknowledgement of well doing are discussed. Finally, this kind of acknowledgement, accreditation, is compared with the other kind of external acknowledgement of well doing: certification, establishing the former as adequate way of controlling not only the measurement process but also the management system.

    2008-01-01

    The Department of Homeland Security National Cyber Security Division supported development of a small set of security ideals as a framework to establish measurable control systems security. Based on these ideals, a draft set of proposed technical metrics was developed to allow control systems owner-operators to track improvements or degradations in their individual control systems security posture. The technical metrics development effort included review and evaluation of over thirty metrics-related documents. On the bases of complexity, ambiguity, or misleading and distorting effects the metrics identified during the reviews were determined to be weaker than necessary to aid defense against the myriad threats posed by cyber-terrorism to human safety, as well as to economic prosperity. Using the results of our metrics review and the set of security ideals as a starting point for metrics development, we identified thirteen potential technical metrics - with at least one metric supporting each ideal. Two case study applications of the ideals and thirteen metrics to control systems were then performed to establish potential difficulties in applying both the ideals and the metrics. The case studies resulted in no changes to the ideals, and only a few deletions and refinements to the thirteen potential metrics. This led to a final proposed set of ten core technical metrics. To further validate the security ideals, the modifications made to the original thirteen potential metrics, and the final proposed set of ten core metrics, seven separate control systems security assessments performed over the past three years were reviewed for findings and recommended mitigations. These findings and mitigations were then mapped to the security ideals and metrics to assess gaps in their coverage. The mappings indicated that there are no gaps in the security ideals and that the ten core technical metrics provide significant coverage of standard security issues with 87% coverage. Based

  5. From “Customary” to “Illegal”: Yao Ethnic Marriages on the Sino-Vietnamese Border

    2015-06-01

    Full Text Available This article examines changing governing practices in the context of the Sino-Vietnamese border in the Guangxi Autonomous Region of China. The groups inhabiting the mountainous ranges of this ethnically diverse part of Southeast Asia evaded the reach of the state until the 1970s, when China and Vietnam started tightening control over the land border after the border war. With an increasingly rigid and clearly delimited Sino-Vietnamese borderland, binary forms of classification began to replace earlier fluid identifications, and the room for diverse social and cultural expressions became restricted. It is within this context that the ethnic marriage practices straddling the borders of China and its southern neighboring states discussed in this article took place. Cross-border ethnic Yao marriages have gone from customary to illegal in recent years as a result of China’s strict population control, its changing demography, and the accelerated shortage of manual labor in its border area. Border politics have permeated the private sphere, transforming common ethnic marriage partners into illegal migrants. Although ethnic marriage partners are relegated to an illegal status, they are indispensible in the local labor market and moral economy as mothers, caretakers, translators, guides, and manual workers. This article argues that, despite being antithetical to the bordering logic of state sovereignty, they are important agents who depend on and capitalize on the border economy.

    that present to medical services for WNV testing and reported to public health officials are the most severe nueroinvasive cases. Much less is understood about the non-neuroinvasive cases with often present with non-descript symptoms. Results Vector mapping: Comparative densities of Ae. aegypti with academic partners of the Entomology and Public Health conducting a study capturing Ae. aegypti may help to enhance environmental programs. Laboratory Capacity: The laboratory training will cover conventional serological methods as well as recently FDA cleared molecular RT-PCR. Participants will include public health laboratory personnel working in molecular and serology diagnostics and other binational partners. Surveillance: A convenient seroprevalence study at sentinel-hospital site of symptomatic patients presenting in Arizona border hospital sites will be performed to better understand circulating levels of arboviral infections. Conclusions Appropriate and timely response to surveillance data is the key to identification human and animal disease associated with WNV, DENV, and other arboviruses. The mosquito vector Ae. aegypti is well established widespread and thriving in Arizona yet there is no autochthonous transmission of DENV identified to date. The results from this study will identify gaps and potential prevention and control measures for emerging infectious diseases including WNV and DENV in Arizona.

    The feasibility of developing a new online monitoring technique based on the characteristic acoustic response of gas bubbles in a liquid has been investigated. The method is intended to monitor the chemistry of the liquid through its relation to the bubble sound frequency. A low-temperature model consisting of water and alcohol mixtures was established, and the frequency of bubbles rising under varying concentrations of methanol was measured. It was shown that the frequency of the sound created by bubble pulsation varies with the percentage of alcohol in water. The frequency drops sharply with the increase in methanol content up to 20 wt pct, after which the decreases is gradual. Surface tension seems to be a critical liquid property affecting the sound frequency through its two-fold effects on the bubble size and the pulsation domain. The dependence between the frequency and the liquid composition suggests the feasibility of developing an acoustic-based technique for process control purposes.

    Natural disasters may lead to infectious disease outbreaks when they result in substantial population displacement and exacerbate synergic risk factors (change in the environment, in human conditions and in the vulnerability to existing pathogens) for disease transmission. We reviewed risk factors and potential infectious diseases resulting from prolonged secondary effects of major natural disasters that occurred from 2000 to 2011. Natural disasters including floods, tsunamis, earthquakes, tropical cyclones (e.g., hurricanes and typhoons) and tornadoes have been secondarily described with the following infectious diseases including diarrheal diseases, acute respiratory infections, malaria, leptospirosis, measles, dengue fever, viral hepatitis, typhoid fever, meningitis, as well as tetanus and cutaneous mucormycosis. Risk assessment is essential in post-disaster situations and the rapid implementation of control measures through re-establishment and improvement of primary healthcare delivery should be given high priority, especially in the absence of pre-disaster surveillance data.

    In the era of economic globalization, strengthen of international cooperation on network education is a general trend. Although China has not made commitments about the market access and national treatment of cross-border supply in Schedule of Specific Commitments on Services, the basic conditions of network education development in China have been met. The Chinese government should formulate strategies for the development of cross-border network education and take relevant measures to implement them. In the near future, the carrying out of cross-border network education in China will become an irreversible trend, and will possess broad prospect with the advance of globalization of Chinese education.

  11. Control of authenticity of Tyrolean milk by stable isotope measurements

    International Nuclear Information System (INIS)

    Full text: Consumers are willing to pay elevated prices for specific product qualities, e.g. for food from a certain region, therefore the declaration of origin of these products needs to be controlled. Conventionally this is done by estimating the flow of goods and by controlling the documentation accompanying the products. However, this means are often not sufficient to detect intentional deception. The measurement of the stable isotope composition of products offers the possibility to investigate the product itself. The stable isotope ratios of the elements H, C, N, O and S are varying geographically due to diverse environmental conditions (e.g.: climate, geology, soil, altitude, geography) thus creating individual patterns for each region. These patterns are transferred in different ways into plants and animals originating from a certain region. Therefore analysis of the stable isotope pattern is a potent tool for geographic differentiation. Tyrolean milk is regarded as a high quality good produced under strict regulations in a special (alpine) environment. To protect Tyrolean milk from incorrectly declared milk originating from other regions/countries, stable isotope investigations have been carried out over a period of one year on samples from all regions of Tyrol. Samples have been measured for isotopic composition of H, C, N and O. The observed variation in the isotopic pattern of the Tyrolean milk within the year can be explained by different feeding regimes during summer and winter. Comparison of the isotopic pattern of the Tyrolean milk and milk samples of the same age from other regions gives evidence for significant differences in the isotope ratios. As the investigated 'non-Tyrolean' samples have been produced in neighbouring regions that should have similar isotopic signals due to comparable environmental conditions, presumably it should be even easier to distinguish between milk from farther regions and milk from Tyrol.

    In this article, we explore a fundamental issue of Cultural Psychology, that is our "capacity to make meaning", by investigating a thesis from contemporary philosophical semantics, namely, that there is a decisive relationship between language and rationality. Many philosophers think that for a person to be described as a rational agent he must understand the semantic content and meaning of the words he uses to express his intentional mental states, e.g., his beliefs and thoughts. Our argument seeks to investigate the thesis developed by Tyler Burge, according to which our mastery or understanding of the semantic content of the terms which form our beliefs and thoughts is an "incomplete understanding". To do this, we discuss, on the one hand, the general lines of anti-individualism or semantic externalism and, on the other, criticisms of the Burgean notion of incomplete understanding - one radical and the other moderate. We defend our understanding that the content of our beliefs must be described in the light of the limits and natural contingencies of our cognitive capacities and the normative nature of our rationality. At heart, anti-individualism leads us to think about the fact that we are social creatures, living in contingent situations, with important, but limited, cognitive capacities, and that we receive the main, and most important, portion of our knowledge simply from what others tell us. Finally, we conclude that this discussion may contribute to the current debate about the notion of borders. PMID:26111737

    Full Text Available “Borders, boundaries and desirable wishes” is the title of the residential workshop offered to a group of young adults (aged 18-25 of the Centro di Salute Mentale (Mental Health Center of the DSM Basaglia of ASL TO2 in Turin. The idea of the workshop, the definition of the objectives and the topics, which are clearly expressed in the title, come from the work of the team dedicated to group psychotherapies, which has been offering group psychodrama sessions to young adults of this age since 2008. In the delicate move to the adult age, these young adults are lost and stuck in static realities where it is not possible to open up to the dimension of desire nor to the transforming encounter with the Other, since they didn’t have the experience of boundaries and lack. These two elements are necessary to acquire the ability to make projects for oneself. During the workshop the following instruments were used: group, psychodrama and art therapy. The group, as a paternal function, ensured the presence of safe boundaries enabling individuals to experiment; psychodrama and art therapy enabled the bodies to experience encounters and transformations, using doing as a metaphor for the movement against the inhibition of doing and as a way to show oneself to the Other and be able to see the Other. 

  15. Languaging the Borders of Europe

    Full Text Available Emerging from a discomfort with the blind spots encountered within and across theorizations of language and space in the field of human geography, in this article, we argue for “making space” for conceptualizations that speak from and through the everyday territories of migrants in Europe today. Inspired by a range of writers thinking postcolonially and multi/trans-lingually, the authors draw on their own embodied migrant experience to argue for re-envisioning Europe’s borders through multiple languaging practices. “Languaging”, in this view, takes linguistic practices in a migrant context as an inherently prosthetic activity, whereby any dominant, national host language is inevitably subject to the subterranean rumblings of all the languages a migrant brings with her on her global journeys. Conceived as being saturated with prosthetic “absence(s”, migrant languaging practices rework cultural geography’s bounded, inward-looking, and security-fixated understanding of the language/territory nexus, the better to open a vital space for re-envisioning language’s everyday territories as sites for translational solidarity and becoming.

    The concept of cross-border regional innovation systems (CBRIS) surfaced in the literature on economic geography through discourses that highlighted the need of broadening innovation systems to cross-border contexts. Since these early discussions, the theoretical backgrounds of CBRIS have been...... elaborated through notions of geographical scale, proximity and related variety in a range of conceptual papers proposing CBRIS as a comprehensive framework for analysing regional cross-border integration. However, the empirical literature on CBRIS has failed to keep up with the advances in conceptualisation...

    Full Text Available SUMMARY The first Argentinian autochthonous human case of visceral leishmaniasis (VL was confirmed in Posadas (Misiones in 2006. Since then, the disease has increased its incidence and geographical distribution. In the 2006-2012 period, 107 human cases were detected (11 deaths. The presence of Lutzomyia longipalpis was detected in peridomiciles in Puerto Iguazú urban area in 2010; some of these findings were associated with households where cases of canine VL had already been reported. The objective of this study was to ascertain the abundance and spatial distribution of Lu. longipalpis in Puerto Iguazú City, on the Argentina-Brazil-Paraguay border. Lu. longipalpis proved to be exclusively urban and was found in 31% of the households sampled (n = 53, 67% of which belonged to areas of low abundance, 20% to areas of moderate abundance and 13% to areas of high abundance. Nyssomyia whitmani was the only species found both in urban and peri-urban environments, and Migonemyia migonei was registered only on the outskirts of the city. Due to the fact that Puerto Iguazú is considered to be at moderate risk at the moment, it is necessary to intensify human and canine case controls, as well as take integrated prevention and control measures regarding the environment, vectors and reservoirs on the Argentina-Brazil-Paraguay border area.

  18. The impact of the EU Directive on patients' rights and cross border health care in Malta.

    The patients' rights and cross-border health care directive was implemented in Malta in 2013. Malta's transposition of the directive used the discretionary elements allowable to retain national control on cross-border care to the fullest extent. This paper seeks to analyse the underlying dynamics of this directive on the Maltese health care system through the lens of key health system stakeholders. Thirty-three interviews were conducted. Qualitative content analysis of the interviews reveals six key themes: fear from the potential impact of increased patient mobility, strategies employed for damage control, opportunities exploited for health system reform, moderate enhancement of patients' rights, negligible additional patient mobility and unforeseen health system reforms. The findings indicate that local stakeholders expected the directive to have significant negative effects and adopted measures to minimise these effects. In practice the directive has not affected patient mobility in Malta in the first months following its implementation. Government appears to have instrumentalised the implementation of the directive to implement certain reforms including legislation on patients' rights, a health benefits package and compulsory indemnity insurance. Whilst the Maltese geo-demographic situation precludes automatic generalisation of the conclusions from this case study to other Member States, the findings serve to advance our understanding of the mechanisms through which European legislation on health services is influencing health systems, particularly in small EU Member States.

    1995-01-01

    Results are presented of an experimental program that investigated the use of a secondary air stream to control the amount of flow through a convergent-divergent nozzle. These static tests utilized high pressure, ambient temperature air that was injected at the throat of the nozzle through an annular slot. Multiple injection slot sizes and injection angles were tested. The introduction of secondary flow was made in an opposing direction to the primary flow and the resulting flow field caused the primary stream to react as though the physical throat size had been reduced. The percentage reduction in primary flow rate was generally about twice the injected flow rate. The most effective throttling was achieved by injecting through the smallest slot in an orientation most nearly opposed to the approaching primary flow. Thrust edliciency, as measured by changes in nozzle thrust coefficient, was highest at high nozzle pressure ratios, NPR. The static test results agreed with predictions obtained prior from PABSD, a fully viscous computational fluid dynamics program. Since use of such an injection system on gas turbine engine exhaust nozzles would be primarily at high NPRs, it was concluded that fluidic control holds promise for reducing nozzle weight and complexity on future systems.

  1. Physical measurements for quality control in industrial radiation sterilization

    International Nuclear Information System (INIS)

    The use of ionizing radiation has brought about a growing industry for the sterilization of disposable surgical equipment, medical supplies, and containers for biological specimens. For many products, irradiation has become an alternative to autoclaving or gas treatment by ethylene oxide. Over fifteen years of experience with industrial sterilization by cobalt-60 gamma radiation have shown that radiation methods provide a clear advantage over gas sterilization, in that sterilization can be performed on non-permeable sealed packages. Moreover, regulatory agencies, such as the Food and Drug Administration in the U.S.A., are reappraising the requirements for sterility assurance. For products released to the public, consideration is now being given to the use of physical dosimetry, i.e., the measurement of radiation dose by physical methods. This is based on a knowledge of the microbial burden of the product before sterilization and on the probability of killing microorganisms by a given radiation dose. Because physical dosimetry is easier to control and less complicated than biological tests, it may be considered in the future the basis for quality assurance of the sterilized product. Some of the problems associated with standardized measurement techniques in radiation sterilization include the choice of dosimetry and its calibration, as well as methods and procedures used to minimize errors due to variations in radiation flux density, source geometry with respect to the product, and environmental factors.

  2. Measurement approaches to support future warhead arms control transparency

    International Nuclear Information System (INIS)

    Transparency on warhead stockpiles, warhead dismantlement, and fissile material stockpiles in nuclear weapons states will become increasingly important in the move beyond START II toward lower quantities of warheads. Congressional support for further warhead reductions will likely depend on the degree of irreversibility, or in other words, the rapidity with which warhead inventories could be reconstituted. Whether irreversibility considerations can be satisfied will depend on monitoring dismantlement as well as constraining the available stockpile of fissile materials for possible refabrication into warheads. Measurement techniques designed to address the above problems will need to consider NPT Article 1 obligations as well as Russian and US classification regulations, which prohibit or restrict the transfer of nuclear warhead design information to other states. Classification considerations currently limit the potential completeness of future inspections of weapons materials. Many conventional international safeguards approaches are not currently viable for arms control applications because they would reveal weapons design information. The authors discuss a variety of technical measures that may help to improve transparence of warhead and fissile material stockpiles and may enable limited warhead dismantlement transparency

    Laser beam propagation underwater is becoming an important research topic because of high demand for its potential applications. Namely, ability to image underwater at long distances is highly desired for scientific and military purposes, including submarine awareness, diver visibility, and mine detection. Optical communication in the ocean can provide covert data transmission with much higher rates than that available with acoustic techniques, and it is now desired for certain military and scientific applications that involve sending large quantities of data. Unfortunately underwater environment presents serious challenges for propagation of laser beams. Even in clean ocean water, the extinction due to absorption and scattering theoretically limit the useful range to few attenuation lengths. However, extending the laser light propagation range to the theoretical limit leads to significant beam distortions due to optical underwater turbulence. Experiments show that the magnitude of the distortions that are caused by water temperature and salinity fluctuations can significantly exceed the magnitude of the beam distortions due to atmospheric turbulence even for relatively short propagation distances. We are presenting direct measurements of optical underwater turbulence in controlled conditions of laboratory water tank using two separate techniques involving wavefront sensor and LED array. These independent approaches will enable development of underwater turbulence power spectrum model based directly on the spatial domain measurements and will lead to accurate predictions of underwater beam propagation.

    Like many other countries in the world, China and Vietnam are now faced with criminals who abduct and sell women and children, which is the ugliest form of human behavior. The purpose for this crime is a common concern and different social situations and changes will generate different purposes, which can be roughly divided into categories such as sex exploitation, labor exploitation, marriage of the poor, reproduction of the male offspring and old age care. Besides, the purposes of cross-border crime might be different because of their different nationalities. The Chinese government spares no effort to crack down such crimes, no matter whether they are committed inside or outside its territory. However, to eradicate the crimes needs the uprooting of their bases and the full cooperation in the international community.

  5. Environmental exposure of road borders to zinc

    International Nuclear Information System (INIS)

    The emissions of zinc along roads originating from tyre wear, corrosion of safety fence and other traffic-related sources have been quantified and validated by measured long-term loads in road run-off and airborne solids (drift) for 29 published case studies. The distribution pattern over the road border at various distances from the edge of the paved surface is assessed on the basis of 38 published case studies with measured concentrations in soil. For the impact assessment, the road border is differentiated into a zone that is part of the 'technosphere' and the 'target zone' beyond that technosphere that can be considered as part of the receiving environment. The 'technosphere' of the road includes the central reservation, the hard and the soft shoulder or, if one or both shoulders are not present, the so-called obstacle 'free zone' that is defined by road engineers. Pollution within the technosphere may require appropriate management of solid disposal and isolation from groundwater to prevent further distribution of pollutants to the environment. In the target zone along regional roads, the zinc load is about 4 mg/m2 year and this is of the same order of magnitude as that of atmospheric deposition in areas beyond the influence of roads (background). In the target zone along highways, the zinc load is increased in comparison to the background deposition. The average load of about 38 mg/m2 year is similar to that in fertilised agricultural land. Because most of the emitted zinc stays in the technosphere, the total amount entering this target zone along highways is limited. From the 140 tons of zinc per year that is released from tyre wear in The Netherlands, 64 tons is emitted in the urban area, 6.5 tons reaches to the target zones of all roads and only 1.1 tons of zinc will enter the target zone along highways. This amount will be further decreased by the application of porous asphalt in the near future. The emission from safety fence corrosion does not enter the

    Full Text Available Discourse theory is useful for understanding the creation of borders, whether material or imaginary. This paper addresses three situations on Mexico’s southern border between 2000 and 2015 in which elements of discourse theory may be applied. The outcomes were the following: 1 correlations may be made between the elements of the discourse moving from the northern to the southern border, but not in the opposite direction; 2 the process of securitising the discourse about migrants is continuous, and new securitising elements are regularly added; 3 an “elastic borders” phenomenon exists, where borders extend or retract, thereby creating new border regions; and 4 discourses around the southern border are constructed with more pejorative elements than the northern, despite the fact that crime rates are higher in the north.

    Full Text Available The purpose of this paper is to emphasize the linkage between establishing crossborder relations and tourism development by focusing on ten tourism projects implemented under Hungary-Romania Cross-Border Co-operation Programme (2007-2013. The study area comprises the two neighbouring counties of Satu Mare and Szabolcs-Szatmár-Bereg, the border connecting two areas characterised by social and economic similarities. Building on a solid foundation, as the first Hungarian-Romanian cross-border initiatives were launched nearly two decades ago, the two counties work together towards the shared aim of developing business infrastructure, cross-border trade, culture and tourism. The present study examines the relevance of cross-border projects viewed from the perspective of sustainable tourism development in two peripheral counties featuring similar resources. Moreover, the investigation is based on consultation of project documents, reports and promotional materials, against the theoretical framework of cross-border cooperation and regional development.

    We investigate the impact of borders on the topology of spatially embedded networks. Indeed territorial subdivisions and geographical borders significantly hamper the geographical span of networks thus playing a key role in the formation of network communities. This is especially important in scientific and technological policy making and highlights the interplay of the internationalization pressure toward a global innovation system against the administrative borders imposed by the national and continental institutions. In this study we introduce an outreach index to quantify the impact of borders on the community structure and apply it to the case of the European and US patent co-inventors networks. We find that (a) the US connectivity decays as a power of distance, whereas we observe a faster exponential decay for Europe; (b) European network communities essentially correspond to nations and contiguous regions while US communities span multiple states across the whole country without any characteristic geog...

    Rising CO(2) levels in the atmosphere have drawn attention to the important role of soil in sequestering carbon. This project goal was to quantify soil carbon deposition associated with border cell release and exudation from root growth zones. Carbon was measured with a Carlo Erba C/N analyzer in soil from the rhizosphere of mature grasses and, in separate experiments, in soil collected around root growth zones. Root border cells in "rhizosphere soil" (silica sand) were counted using a compound microscope after soil sonication and extraction with surfactant. For sand-grown Bromus carinatus, Zea mays, and Cucumis sativus, young seedlings (with roots shorter than 2 cm) released thousands of border cells, while older root tips released only hundreds. For a variety of native annual and perennial grasses and invasive annual grasses (Nassella pulchra, B. carinatus, B. diandrus, B. hordeaceus, Vulpia microstachys, Aegilops triuncialis, Lolium multiflorum, Zea mays), the rhizosphere of mature root systems contained between 18 and 32 μg C g(-1) sand more than that of the unplanted controls. Spatial analysis of the rhizosphere around the cucumber growth zone confirmed C enrichment there. The root tip provided C to the rhizosphere: 4.6 μg C in front of the growing tip, with the largest deposition, 20.4 μg C, to the rhizosphere surrounding the apical 3 mm (root cap/meristem). These numbers from laboratory studies represent the maximum C that might be released during flooding in soils. Scaling up from the organ scale to the field requires a growth analysis to quantify root tip distributions in space and time.

  17. Radiation monitoring at the borders - Important part of nuclear security

    International Nuclear Information System (INIS)

    Full text: Three factors place Central Asia and Uzbekistan as its part in a key global non-proliferation position: the proximity of nuclear neighbours, the proximity of states and other groups seeking nuclear/radioactive material and know-how, and indigenous sources of nuclear/radioactive material. The nuclear threat is of special concern because of the proximity of major nuclear states such as Russia and China, states with nuclear ambitions such as Iran, and non-state actors potentially seeking nuclear and/or radioactive materials. In addition, Central Asia possesses currently functioning nuclear facilities widely using powerful radioactive sources from Soviet times and active uranium mines. The geographical location of Uzbekistan is convenient for illicit trafficking of nuclear materials. In conditions of increasing threat of nuclear terrorism, when extremist organizations arc threatening to mankind with terrorist attacks including the use of nuclear devices or radiological dispersal and exposure devices ('dirty' bomb), the problem to stop illicit trafficking of nuclear and radioactive materials is becoming the world one. In the frame of the Second Line of Defence (SLD) Core Program which is part of the Office of the Second Line of Defence, in the Office of International Material Protection and Cooperation of the US Department of Energy's National Nuclear Security Administration Uzbekistan borders were equipped with radiation control devices. The mission of the Core Program is to rapidly reduce the risk of nuclear proliferation and illicit trafficking of special nuclear and other radiological materials by cooperating with host countries to improve their detection and interdiction capabilities at strategic international border crossings, mid-sized seaports, and airports. To solve the problem of radiation monitoring in Uzbekistan was possible by installing stationary portal radiation monitors at main customs border crossings or entry points. Their high sensitivity

  20. Measuring and test equipment control through bar-code technology

    International Nuclear Information System (INIS)

    Over the past several years, the use, tracking, and documentation of measuring and test equipment (M ampersand TE) has become a major issue. New regulations are forcing companies to develop new policies for providing use history, traceability, and accountability of M ampersand TE. This paper discusses how the Fast Flux Test Facility (FFTF), operated by Westinghouse Hanford Company and located at the Hanford site in Rich- land, Washington, overcame these obstacles by using a computerized system exercising bar-code technology. A data base was developed to identify M ampersand TE containing 33 separate fields, such as manufacturer, model, range, bar-code number, and other pertinent information. A bar-code label was attached to each piece of M ampersand TE. A second data base was created to identify the employee using the M ampersand TE. The fields contained pertinent user information such as name, location, and payroll number. Each employee's payroll number was bar coded and attached to the back of their identification badge. A computer program was developed to automate certain tasks previously performed and tracked by hand. Bar-code technology was combined with this computer program to control the input and distribution of information, eliminate common mistakes, electronically store information, and reduce the time required to check out the M ampersand TE for use

    ABSTRACT The root-knot nematode Meloidogyne incognita is a major pathogen of a range of important crops. Currently, control is typically achieved by the use of nematicides. However, recent work suggests that manipulating the ability of roots to slough off border cells, which then act as a decoy to the nematode, can significantly decrease damage to the roots. We investigated the attractiveness of border cells to M. incognita and the response of the nematode to border cells in close proximity. We found very limited attraction, in that nematodes did not preferentially alter direction to move toward the border cells, but a large and significant increase in nematode speed was observed once they were in the immediate vicinity of border cells. We discuss the results in the context of physical and biological mechanisms in relation to the control of pathogenic nematodes.

    This article aims to analyze the malaria surveillance situation on the triple border between Brazil, Colombia, and Peru. This was a qualitative study using questionnaires in the border towns in 2011. The results were analyzed with the SWOT matrix methodology, pointing to significant differences between the malaria surveillance systems along the border. Weaknesses included lack of linkage between actors, lack of trained personnel, high turnover in teams, and lack of malaria specialists in the local hospitals. The study also showed lack of knowledge on malaria and its prevention in the local population. The strengths are the inclusion of new institutional actors, improvement of professional training, distribution of insecticide-treated bed nets, and possibilities for complementary action between surveillance systems through cooperation between health teams on the border. Malaria control can only be successful if the region is dealt with as a whole.

    We conducted a prevalence study of mutations in Plasmodium falciparum that are associated with antimalarial drug resistance at a rural site in Karonga near Malawi's northern border with Tanzania. We found a higher prevalence of the key chloroquine resistance-conferring mutation in the pfcrt gene (K76T) at this site in comparison with the prevalence in Blantyre, a city in the south of Malawi, far from an international border (9%vs. 0%; P Malawi was recently reported to be over 50%. Our findings suggest a considerable 'leakage' of parasite antimalarial drug resistance across the border between two countries with different national malaria control policies and with different levels of resistance. Neighbouring countries should consider implementing common regional rather than national malaria treatment policies to prevent the spread of antimalarial drug resistance alleles across their borders.

    Full Text Available There are hundreds of departments and organizations working on border health issues in the California/Baja California border region trying to protect and improve health without a collaborative structure that integrates jurisdictions and organizations. As a result, there is a need to effectively improve the health in the border region by coordinating these organizations to work together and benefit from each other’s best practices. The newly developed California Border Health Collaborative (CBHC can provide the leadership and collaborative culture to positively improve the health of the border region. This article aims to describe the development process of this collaborative to include key ingredients to success, the roles of mulit-level jurisdictions, and policy implications.This article describes the methods used to develop key aspects of collaborative leadership, strategic alignment and a common vision toward the building of this collective impact approach to border health. In addition, we describe the role of key local County (County of San Diego Live Well San Diego initiative, State, (California Department of Public Health- Office of Binational Border Health, Federal (US-Mexico Border Health Commission’s Leaders across Borders, Academia (e.g., University of California San Diego and San Diego State University and non-profit entities (e.g., Project Concern International, San Ysidro Health Center in forming the BHCC. Evaluating the consortium development process included a literature review of similar processes, a review of internal documents and an analysis of developmental events. To this point the CBHC has built a strong, cohesive collaborative on the U.S. side of the border. It is sharing and leveraging local expertise to address many border health issues. Even more importantly, the BHCC has reached a key stage in which it can effectively engage its Baja California, Mexico counterparts in a manner that will prove extremely powerful

  6. A modified GHG intensity indicator: Toward a sustainable global economy based on a carbon border tax and emissions trading

    International Nuclear Information System (INIS)

    It will be difficult to gain the agreement of all the actors on any proposal for climate change management, if universality and fairness are not considered. In this work, a universal measure of emissions to be applied at the international level is proposed, based on a modification of the Greenhouse Gas Intensity (GHG-INT) measure. It is hoped that the generality and low administrative cost of this measure, which we call the Modified Greenhouse Gas Intensity measure (MGHG-INT), will eliminate any need to classify nations. The core of the MGHG-INT is what we call the IHDI-adjusted Gross Domestic Product (IDHIGDP), based on the Inequality-adjusted Human Development Index (IHDI). The IDHIGDP makes it possible to propose universal measures, such as MGHG-INT. We also propose a carbon border tax applicable at national borders, based on MGHG-INT and IDHIGDP. This carbon tax is supported by a proposed global Emissions Trading System (ETS). The proposed carbon tax is analyzed in a short-term scenario, where it is shown that it can result in a significant reduction in global emissions while keeping the economy growing at a positive rate. In addition to annual GHG emissions, cumulative GHG emissions over two decades are considered with almost the same results. - Highlights: ► An IHDI-adjusted GDP (IHDIGDP) is introduced to universally account the activities of nations. ► A modified GHG emission intensity (MGHG-INT) is introduced based on the IHDIGDP. ► Based on green and red scenarios, admissible emissions and RED percentage are introduced. ► The RED percentage is used to define a border carbon tax (BCT) and emission trading system. ► The MGHG-INT can provide a universal control on emissions while allowing high economical growth

    Full Text Available One of the objectives of the European Union enshrined in 67 alin.(1 (ex-art. 61 TCE and ex-art. 29 TUE of the consolidated version of the Treaty on European Union is to create a common European space of security and justice without internal frontiers, in which to ensure the free movement of people, corralated with appropriate measures on external border controls , asylum , immigration, and crime prevention and combating. This is a long term goal that requires active cooperation of Member States and multiple efforts by EU institutions. The institutional functioning practice has shown that the clasic forms of judicial cooperation do not have the ability to complete this objective and that is necessary to create specialized structures. In this context the First European institutional structure was established in 2002, a specialized agency of the European Union, named Eurojust, with the main objective to promote and improve coordination and cooperation between the judicial authorities of the Member States in the fight against serious cross-border crime affecting the European Union. Tasks of Eurojust and relations with other European bodies, particularly the Council and Commission are established by Decision 2002/187 / JHA amended by Decision 2009/426 / JHA Council of 16 December 2008 It is exercised by College Eurojust or through its national members.

    2011-01-01

    Territorial subdivisions and geographic borders are essential for understanding phenomena in sociology, political science, history, and economics. They influence the interregional flow of information and cross-border trade and affect the diffusion of innovation and technology. However, most existing administrative borders were determined by a variety of historic and political circumstances along with some degree of arbitrariness. Societies have changed drastically, and it is doubtful that currently existing borders reflect the most logical divisions. Fortunately, at this point in history we are in a position to actually measure some aspects of the geographic structure of society through human mobility. Large-scale transportation systems such as trains and airlines provide data about the number of people traveling between geographic locations, and many promising human mobility proxies are being discovered, such as cell phones, bank notes, and various online social networks. In this chapter we apply two optimiz...

    2009-10-01

    Full Text Available In this paper the border is evaluated as a fold of power relations in which sovereign capacity and competence is marshalled alongside strategies of control, surveillance, and risk management to constitute, what we call, a zone of frontier government. We advance the argument that the border is a site for both negative and positive power, for insertion and subtraction, and that the assemblage of surveillance and compliance regimes are "run" not so much in the furtherance of a precautionary or pre-emptive end-state, but as intermediate values that are sufficiently malleable by an invigorated sovereign, expressed in the residue of discretion in and between the many border agencies.  Our analysis is based on extensive policy and program documents, as well as twenty-five interviews with officials in various agencies engaged in the US-Canada and, particularly, the Windsor-Detroit corridor.

  11. Extracellular proteins in pea root tip and border cell exudates.

    2007-02-01

    Newly generated plant tissue is inherently sensitive to infection. Yet, when pea (Pisum sativum) roots are inoculated with the pea pathogen, Nectria haematococca, most newly generated root tips remain uninfected even though most roots develop lesions just behind the tip in the region of elongation. The resistance mechanism is unknown but is correlated spatially with the presence of border cells on the cap periphery. Previously, an array of >100 extracellular proteins was found to be released while border cell separation proceeds. Here we report that protein secretion from pea root caps is induced in correlation with border cell separation. When this root cap secretome was proteolytically degraded during inoculation of pea roots with N. haematococca, the percentage of infected root tips increased from 4% +/- 3% to 100%. In control experiments, protease treatment of conidia or roots had no effect on growth and development of the fungus or the plant. A complex of >100 extracellular proteins was confirmed, by multidimensional protein identification technology, to comprise the root cap secretome. In addition to defense-related and signaling enzymes known to be present in the plant apoplast were ribosomal proteins, 14-3-3 proteins, and others typically associated with intracellular localization but recently shown to be extracellular components of microbial biofilms. We conclude that the root cap, long known to release a high molecular weight polysaccharide mucilage and thousands of living cells into the incipient rhizosphere, also secretes a complex mixture of proteins that appear to function in protection of the root tip from infection.

  12. Measurement and control of electron-phonon interactions in graphene

    Science.gov (United States)

    Remi, Sebastian

    Despite the weak interaction between electrons and atomic vibrations (phonons) in the one-atom thick crystal of carbon called graphene, the scattering of electrons off phonons limits coherent electron transport in pristine devices over mesoscopic length scales. The future of graphene as a replacement to silicon and other materials in advanced electronic devices will depend on the success of controlling and optimizing electronic transport. In this dissertation, we explore the electron-phonon interaction via Raman scattering, elucidating the effects of filling and emptying charge states on the phonons in both the metallic state and when levels are quantized by an applied perpendicular magnetic field. In zero magnetic field, the phonon energy shifts due to electronic screening by charge carriers. Previously, a logarithmic divergence of the phonon energy was predicted as a function of the charge carrier density. For the first time, we observe signatures of this logarithmic divergence at liquid He temperatures after vacuum annealing on single layers. We also measure the electron-phonon coupling strength, Fermi velocity, and broadening of electronic quantum levels from Raman scattering and correlate these parameters to electronic transport. In a strong perpendicular magnetic field, the energy bands split into discrete Landau levels. Here, we observe kinks and splitting of the optical phonon energy, even when the Landau level transitions are far from resonant with the phonons. We discover that the kinks are attributed to charge filling of Landau levels, as understood from a linearized model based on electron-phonon interactions. Moreover, we show that material parameters determined without magnetic fields also describe phonon behavior in high magnetic fields.

  15. Hardness and Approximation of The Asynchronous Border Minimization Problem

    CERN Document Server

    Popa, Alexandru; Yung, Fencol C C

    2010-01-01

    We study a combinatorial problem arising from microarrays synthesis. The synthesis is done by a light-directed chemical process. The objective is to minimize unintended illumination that may contaminate the quality of experiments. Unintended illumination is measured by a notion called border length and the problem is called Border Minimization Problem (BMP). The objective of the BMP is to place a set of probe sequences in the array and find an embedding (deposition of nucleotides/residues to the array cells) such that the sum of border length is minimized. A variant of the problem, called P-BMP, is that the placement is given and the concern is simply to find the embedding. Approximation algorithms have been previously proposed for the problem but it is unknown whether the problem is NP-hard or not. In this paper, we give a thorough study of different variations of BMP by giving NP-hardness proofs and improved approximation algorithms. We show that P-BMP, 1D-BMP, and BMP are all NP-hard. Contrast with the pre...

    2014-01-01

    We investigate the impact of borders on the topology of spatially embedded networks. Indeed territorial subdivisions and geographical borders significantly hamper the geographical span of networks thus playing a key role in the formation of network communities. This is especially important in scientific and technological policy-making, highlighting the interplay between pressure for the internationalization to lead towards a global innovation system and the administrative borders imposed by the national and regional institutions. In this study we introduce an outreach index to quantify the impact of borders on the community structure and apply it to the case of the European and US patent co-inventors networks. We find that (a) the US connectivity decays as a power of distance, whereas we observe a faster exponential decay for Europe; (b) European network communities essentially correspond to nations and contiguous regions while US communities span multiple states across the whole country without any characteristic geographic scale. We confirm our findings by means of a set of simulations aimed at exploring the relationship between different patterns of cross-border community structures and the outreach index. PMID:24686380

    2011-02-01

    This paper describes a digital radiography (DR) quality control protocol for DR detectors from the forthcoming report from the Institute of Physics and Engineering in Medicine (IPEM). The protocol was applied to a group of six identical caesium iodide (CsI) digital x-ray detectors to assess reproducibility of methods, while four further detectors were assessed to examine the wider applicability. Twelve images with minimal spatial frequency processing are required, from which the detector response, lag, modulation transfer function (MTF), normalized noise power spectrum (NNPS) and threshold contrast-detail (c-d) detectability are calculated. The x-ray spectrum used was 70 kV and 1 mm added copper filtration, with a target detector air kerma of 2.5 µGy for the NNPS and c-d results. In order to compare detector performance with previous imaging technology, c-d data from four screen/film systems were also acquired, at a target optical density of 1.5 and an average detector air kerma of 2.56 µGy. The DR detector images were typically acquired in 20 min, with a further 45 min required for image transfer and analysis. The average spatial frequency for the 50% point of the MTF for six identical detectors was 1.29 mm-1 ± 0.05 (3.9% coefficient of variation (cov)). The air kerma set for the six systems was 2.57 µGy ± 0.13 (5.0% cov) and the NNPS at this air kerma was 1.42 × 10-5 mm2 (6.5% cov). The detective quantum efficiency (DQE) measured for the six identical detectors was 0.60 at 0.5 mm-1, with a maximum cov of 10% at 2.9 mm-1, while the average DQE was 0.56 at 0.5 mm-1 for three CsI detectors from three different manufacturers. Comparable c-d performance was found for these detectors (5.9% cov) with an average threshold contrast of 0.46% for 11 mm circular discs. The average threshold contrast for the S/F systems was 0.70% at 11 mm, indicating superior imaging performance for the digital systems. The protocol was found to be quick, reproducible and gave an in

    2010-01-01

    Background: Dermoscopy is one of the major imaging modalities used in the diagnosis of melanoma and other pigmented skin lesions. Due to the difficulty and subjectivity of human interpretation, computerized analysis of dermoscopy images has become an important research area. One of the most important steps in dermoscopy image analysis is the automated detection of lesion borders. Methods: In this article, we present a systematic overview of the recent border detection methods in the literature paying particular attention to computational issues and evaluation aspects. Conclusion: Common problems with the existing approaches include the acquisition, size, and diagnostic distribution of the test image set, the evaluation of the results, and the inadequate description of the employed methods. Border determination by dermatologists appears to depend upon higher-level knowledge, therefore it is likely that the incorporation of domain knowledge in automated methods will enable them to perform better, especially in ...

  1. Frontex, the Euro-Mediterranean border and the paradoxes of humanitarian rhetoric

    Directory of Open Access Journals (Sweden)

    Giuseppe Campesi

    2014-09-01

    Full Text Available The article explores the ambiguous dialectic between the technocratic ideology of risk management and the recurrent call for emergency measures which characterizes Euro-Mediterranean border control policies, showing how Frontex has ultimately succeeded in capitalising on the recurring cry to humanitarian emergencies coming from some Member Countries. Far from seeing its legitimacy undermined as a risk management agency that should predict and prevent potential migratory crisis, it has incorporated the emergency rethoric into its official communication, making it a legitimating tool for a steady expansion of its role, prerogatives and resources to the detriment of alternative actors in migration policy. This reproduces the paradoxes of a humanitarian policy which is intended at protecting the bare life of migrants and asylum seekers, while violating their fundamental rights to escape and find asylum elsewhere.

  2. TACTICS OF BORDER CROSSING MOVEMENT: EXPLORING THE MOBILITY OF BRAZILIANS THROUGH THE SCHENGEN AND UK AIRSPACE

    Gustavo Dias

    2015-08-01

    Full Text Available This paper addresses the relations between migrants, mobility, tactics, negotiation, and the contemporary definition of borders in the aftermath of 9/11.The empirical focus of this paper is how Brazilians from Alto Paranaiba journey through airports located in the Schengen area and in the British territory to London. As a main research orientation, I use the notion of journey as approached by mobility studies, where actions and skills remain an important link between the wayfarer and the social space in which s/he moves through, the embodied practice to how we grasp the world. Migrants deal and struggle against border regime, but they are not powerless social actors. They rather produce creative resistance to reinvent their journey through the surveillance apparatus, which manage and delimit places with targets and threats. In this process, I explore the notion of border crossing movement as a tactical mobility developed by migrants to overcome the border control imposed by governments in airports. The article was drawn through fieldwork conducted initially in London, between 2009 and 2013, and afterwards in Alto Paranaiba, during 2013. The ethnographic study consisted in semi-structured interviews, participant observation through snowball technique, which enabled me to access a considerable number of participants in these two regions explored. The argument that I develop is that migrants as social actors are part important in the dialogue produced between border crossing and border reinforcement.

  3. Species-dependent effects of border cell and root tip exudates on nematode behavior.

    2000-11-01

    ABSTRACT Effects of border cell and root tip exudates on root knot nematode (Meloidogyne incognita) behavior were examined. In whole-plant assays using pea, M. incognita second-stage juveniles (J2) accumulated rapidly around the 1- to 2-mm apical region ensheathed by border cells, but not in the region of elongation. Within 15 to 30 min, J2 which had accumulated within detached clumps of border cells lost motility and entered into a quiescent state. When border cells (and associated root tip exudates) were washed from pea roots prior to challenge with nematodes, no such accumulation and quiescence was induced. Attraction of nematodes by roots was species dependent: no attraction or accumulation occurred in snap bean. Using a quantitative assay, three categories of chemotaxis responses occurred: attraction (pea and alfalfa cv. Thor), repulsion (alfalfa cv. Moapa 69), and no response (snap bean and alfalfa cv. Lahonton). In contrast, total root tip exudates from all three plant species acted as a repellent for M. incognita in the sand assay. An in vitro assay was developed to characterize the induced quiescence response. When total root tip exudate from the tested legumes (as well as corn) was incubated with J2 populations, >80% of the nematodes lost motility. A similar response occurred in Caenorhabditis elegans. Border cell exudates did not induce or contribute to the induction of quiescence. Cocultivation of pea border cells with M. incognita resulted in changes in border cell shape similar to those observed in response to exogenous plant hormones. No such changes occurred in snap bean border cells. Understanding the cell- and host-specific extracellular recognition that occurs between roots and pathogenic nematodes in the early stages before infection occurs could lead to new avenues for disease control.

We find that fluxes are faster in aqueous solutions than in hexane, which is attributed to the hydrophilic nature of the porous membranes and differences in wettability. The impact of an applied magnetic flux gradient, which induces magnetization and motion, on permeation is also examined. Surface chemistry plays an important role in determining flux through porous media such as in the environment. Diffusive flux of nanoparticles through alkylsilane modified porous alumina is measured as a model for understanding transport in porous media of differing surface chemistries. Experiments are performed as a function of particle size, pore diameter, attached hydrocarbon chain length and chain terminus, and solvent. Particle fluxes are monitored by the change in absorbance of the solution in the receiving side of a diffusion cell. In general, flux increases when the membranes are modified with alkylsilanes compared to untreated membranes, which is attributed to the hydrophobic nature of the porous membranes and differences in wettability. We find that flux decreases, in both hexane and aqueous solutions, when the hydrocarbon chain lining the interior pore wall increases in length. The rate and selectivity of transport across these membranes is related to the partition coefficient (Kp) and the diffusion coefficient (D) of the permeating species. By conducting experiments as a function of initial particle concentration, we find that KpD increases with increasing particle size, is greater in alkylsilane--modified pores, and larger in hexane solution than water. The impact of the alkylsilane terminus (--CH3, --Br, --NH2, --COOH) on permeation in water is also examined. In water, the highest KpD is observed when the membranes are modified with carboxylic acid terminated silanes and lowest with amine terminated silanes as a result of electrostatic effects during translocation. Finally, the manipulation of magnetic nanoparticles for the controlled formation

    2004-01-01

    A few months after the signature of the agreement giving the go-ahead for the expansion of CERN into French territory (see Bulletin no.24/2004), work began on the Super Proton Synchrotron (SPS). Two years later, on 31 July 1974, the Robbins tunnel-boring machine excavating the SPS tunnel returned to its starting point (see photograph). It had excavated a tunnel with a circumference of 7 kilometres, at an average depth of 40 metres below the surface. The tunnel straddled the Franco-Swiss border, making the SPS the first cross-border accelerator. More than a thousand magnets were needed to equip the ring. The civil engineering and installation work was completed in record time after only four years. The SPS was equipped with a control system which was ahead of its time, consisting of 24 small control computers distributed in the tunnel and the control room and communicating by means of a high-rate data transmission system. The main control room housed only four consoles as opposed to the banks of electronic ...

  8. An Automatic Statistical Method to detect the Breast Border in a Mammogram

    Directory of Open Access Journals (Sweden)

    Wai Tak (Arthur Hung

    2007-03-01

    Full Text Available Segmentation is an image processing technique to divide an image into several meaningful objects. Edge enhancement and border detection are important components of image segmentation. A mammogram is a soft x-ray of a woman's breast, which is read by radiologists to detect breast cancer. Recently, digital mammography is also available. In order to do computer aided detection on mammogram, the image has to be either in digital form or digitized. A preprocessing step to a digital/digitized mammogram is to detect the breast border so as to minimize the area to search for breast lesion. An enclosed curve is used to define the breast area. In this paper we propose a modified measure of class separability and used it to select the best segmentation result objectively, which leads to an improved border detection method. This new method is then used to analyze a test set of 35 mammograms. The breast border of these 35 mammograms was also traced manually twice to test for their repeatability using Hung's method1. The borders obtained from the proposed automatic border detection method are shown to be of better quality than the corresponding ones traced manually.

    Matthews, Charles Edwards; Wooten, Wilma; Gomez, María Gudelia Rangel; Kozo, Justine; Fernandez, April; Ojeda, Victoria D

    2015-01-01

    There are hundreds of people and organizations working on border health issues in the California-Baja California border region trying to protect and improve health. These efforts are being conducted without a collaborative structure that integrates jurisdictions and organizations. Thus, there is a need to coordinate these organizations to work together and benefit from their collective effort and each other's best practices. The outcome of such an effort could effectively improve the health in the border region. The newly developed "California Border Health Collaborative" unites organizations and provides the leadership and collaborative culture to positively improve the health of the border region; it is referred to as the "Collaborative." This article describes the developmental process of this Collaborative, including partner engagement, governance, strategic planning, key elements for success, the roles of multi-level jurisdictions, and policy implications. This paper focuses on describing the preparation and processes that created the U.S./California side of this binational collaborative effort and is a strong reflection of the theory of border collaboration as described by Denman and De Sonora (1) in "Working beyond Borders: A Handbook for Transborder Projects in Health."

    Full Text Available Soil pollution results from the build up of contaminants, toxic compounds, radioactive materials, salts, chemicals and cancer-causing agents. The most common soil pollutants are hydrocarbons, heavy metals (cadmium, lead, chromium, copper, zinc, mercury and arsenic, herbicides, pesticides, oils, tars, PCBs and dioxins. Soil Electrical Conductivity (EC is one of the soil physical properties w hich have a good relationship with the other soil characteristics. As measuring soil electrical conductivity is easier, less expensive and faster than other soil properties measurements, using a detector that can do on the go soil EC measurements is a good tool for obtaining useful information about soil pollution condition.

  11. Crossing the Borders: An Eco-cinecritical Analysis of Plant Wars and Bird Without Borders

    Directory of Open Access Journals (Sweden)

    Hsiao-Ching Li

    2011-01-01

    Full Text Available This essay reads two Asian nature-oriented films from the perspective of ecocinecriticism,an ecologically minded film criticism. Plant Wars, produced by PTSTaiwan, questions the demarcation between native plants and exotic plants as well asbetween plants and human beings so as to remap the in-between border area. Thestorytelling method it applies is to feature 14 currently native plants as the maincharacters, and illustrates their relationship to aboriginal people, farmers, beekeepersand to other insect species. Bird Without Borders, also produced by PTS, tells the storyof the migration journey of a group of black-faced spoonbills flying 16,000 kilometersall the way from Tainan, Taiwan, to Japan, along the border of South and North Korea,to a remote island of China to look for feeding places and then back to Taiwan to spendthe winter. Different layers of border-crossing are shown in Bird. One similarity ofthese two PTS productions is the search for border-crossing so as to redefine or revisewhat the border means. Plant questions the biological categorization of the native plantsand the exotic plants; Bird illustrates how the crew physically follows the route of thebirds’ flight which crosses the national borders to provide a vision of remapping thenatural territory through challenging the idea of a fixed “place.” Both are seeking forways to trespass the man-made borders: Plant via environmental imagination; Bird viasome physical movement. While the title of Plant Wars seemingly expresses its positionmore strongly through “wars,” Bird Without Borders explicitly asserts a dream of noborders.

    2002-01-01

    Recent studies of border effects have focused on the intra-country and inter-country comparison of trade flows. It is found that borders have a negative impact on the size of cross-border trade. In order to estimate border effects on a regional level one needs not only data on inter-country but also on intra-country trade. For many countries (regional) data on intra-country trade are simply lacking, which makes an analysis of border effects and border regions cumbersome. In this paper we take...

    2016-01-01

    Aims and Objectives: The purpose of the study was to determine the effect of border molding on the retention of the maxillary denture base. Materials and Methods: Two special trays, one with full extensions to the periphery and one 2 mm short from the borders were made on the cast obtained from the preliminary impression. Border molding was done on the tray which was short from borders. On both trays, the final impression was made with zinc oxide eugenol impression paste. Heat cure denture bases were fabricated on the prepared casts and retention was measured using specially designed instrument. Observations and Results: Mean force with border molding (2765.0 g) was larger than mean force without border molding (1805.0 g) at P < 0.01 level. In terms of percentage, too, the mean improvement (59.4%) in force of dislodgement was statistically highly significant (i.e. P < 0.01). Clinical Significance: The results of the present study suggest that the dentures made with border molding will provide better retentive force than the dentures made without border molding.

  15. Emission control through primary measures in biomass combustion

    Energy Technology Data Exchange (ETDEWEB)

    Houshfar, Ehsan; Skreiberg, Oeyvind; Loevaas, Terese

    2010-07-01

    Full text: Biomass as one of the renewable sources of energy and the only carbon containing renewable resource is known as a collective term for many different forms of combustible material derived from plant sources. It can be material that has been taken from a primary production process (chip wood from forestry) or re-claimed material (such as used, clean untreated pallets, waste). To utilize biomass, the conversion pathway could be done in three different ways: thermochemical, biological and physical. Thermochemical technology (including pyrolysis, gasification and combustion) is the most widely used technology to utilize biomass. In addition to the three main elements: O, H and C as the major part, there are also some other minor or trace elements included in the biomass structure such as N, S, Cl and ash elements, contributing to emissions and operational problems (e.g. corrosion and fouling) To avoid emissions, both primary measures and secondary measures can be used. Primary measures are used to avoid creation of these emissions, while secondary measures remove the emissions from the exhaust gas. Thus primary measures are dealing with the combustion zone and improvements to this area, while secondary measures look at the exit of combustion chamber, i.e. the flue gas, to reduce the emission levels. Incomplete combustion of biomass will lead to carbon monoxide, hydrocarbons, particulate matter and polycyclic aromatic hydrocarbons, while complete combustion will lead to NOx and SOx emissions. SCR and SNCR are common secondary measures to reduce NOx emissions. LCA studies have shown that the main pollutant from wood combustion will be NOx, with an emission impact factor as high as 38.6%. Staging technologies (i.e., air-staging and fuel-staging) and flue gas recirculation are possible primary measures to reduce the NOx emission level from biomass combustion. Staged air combustion is maybe the most effective method of NOx emission reduction by primary measures

    2011-06-01

    Wireless sensor networks have been proposed as promising candidates to provide automated monitoring, target tracking, and intrusion detection for border surveillance. In this paper, we demonstrate an ad-hoc wireless sensor network system for border surveillance. The network consists of heterogeneously autonomous sensor nodes that distributively cooperate with each other to enable a smart border in remote areas. This paper also presents energy-aware and sleeping algorithms designed to maximize the operating lifetime of the deployed sensor network. Lessons learned in building the network and important findings from field experiments are shared in the paper.

  2. Measuring Effectiveness of Persuasive Games Using an Informative Control Condition

    Directory of Open Access Journals (Sweden)

    Mara Soekarjo

    2015-06-01

    Full Text Available Research about the effectiveness of persuasive games is still emerging. This article presents a literature review of studies that empirically evaluate the effectiveness of persuasive games. The review concluded that limited empirical evidence is currently available to prove their effectiveness in attitude change. It further revealed that almost no study employed an informative control condition, making it difficult to conclude that the game was more effective than a control condition. Next, in a pretest-posttest design an empirical study tested whether change in attitude was different for people playing the persuasive game "EnerCities" compared to a control condition where participants read a document with highly similar information. No significant differences in increase of attitude or knowledge between participants that played the game and participants in the informative control condition were found. Based on the results of the literature review and the empirical study presented, it hence cannot be concluded that playing a game leads to a greater change in attitude or knowledge acquisition than experiencing conventional media would. Future work should employ designs with proper control conditions and focus on which game features lead to significant effects.

Performance is analyzed taking into account the typical excitations in attitude and linear motion seen in marine applications. The use is for control of fast crafts, ROV and AUV heading, roll, pitch and heave control. The influence on performance given by utilization of external information from velocity log and more accurate heading devices is also analyzed. Typical performance of this low cost type of technology is shown.

  4. A NEW APPROACH FOR BORDER EXTRACTION USING MORPHOLOGICAL METHODS

    Directory of Open Access Journals (Sweden)

    M Rama Bai

    2010-08-01

    Full Text Available The objective of border detection is to mark the points in a digital image at which the luminous intensity changes sharply. Acute changes in image features usually reflect important events and changes inproperties of the world. These include (a discontinuities in depth (b discontinuities in surface orientation (c changes in material properties and (d variations in scene illumination. A novel algorithm based on multi-scale morphological method for the purpose of border detection is introduced. Standard morphological border detection methods use single and symmetrical structure elements which are used exhaustively in image processing. They could detect the alterations of gray level, but are difficult to detect complex border feature because they are only sensitive to image border which has the same direction of structure elements. A new border detection method based on multi-structure element morphology of eight different directions is proposed. The ability of the proposed detection method is that we get eight different border detection results by using morphological gradient algorithm respectively and final border result is obtained by using synthetic weighted method. The experimental result shows that the proposed algorithm obtains clear and exact borders of the image by retaining the image details and it out performs the conventional morphological border detection algorithms and differential border detection operators. This technique shows the worth of border detection and the ability of detecting sharp complex borders.

    2015-02-01

    In tactile scanning profiler, the measuring force would change in a wide range when it was used for profile measurement in a large range, which could possibly destroy the measured surface. To solve the problem, measuring force control system for tactile scanning profiler was needed. In the paper, a voice coil motor-based measuring force control system for tactile scanning profiler was designed. In the design, a low stiffness coefficient spring was used to provide contact force, while a voice coil motor (VCM) to balance the spring force so that the contact force could be kept for constant measuring force. A VCM was designed specially, and for active measuring force control, a precision current source circuit under the control of a DSP unit was designed to drive the VCM. The performance of voice coil motor based measuring force control system had been tested, and its good characteristics were verified.

    Hjertaker, Bjorn T.; Johansen, Geir A.; Jackson, Peter

    2001-07-01

    Level monitoring instrumentation is an essential part of hydrocarbon processing facilities, and has, together with separator technology, been widely addressed over the last decade. Key issues are production capacity, product enhancement, and well-flow control. The reliability and accuracy of the level instrumentation, and its ability to monitor all the interface layers of the separator, including the thickness of the foam and the oil-water emulsion, are particularly important when considering the level instrumentation as the main sensing element in the automatic control of the separator vessel. Lately, industry focus has been placed on optimal automatic control to improve the quality of the production output, and to minimize the use of expensive and environmentally undesirable separation enhancing chemicals. Recent developments in hydrocarbon production include subsea separation stations, where the constraints placed on the reliability and accuracy of the level instrumentation are especially demanding. This paper presents level interface monitoring developments based on electrical, ultrasonic, thermal, and nucleonic physical principles for three-phase hydrocarbon separators, and introduces the notion of tomometry, meaning multi-point cross-sectional metering aiming to acquire information on the cross-sectional flow-component distribution in the process vessel intended for control purposes.

  1. Assessing Measurement Noise Effect in Run-to-Run Process Control: Extends EWMA Controller by Kalman Filter

    Directory of Open Access Journals (Sweden)

    Tzu-Wei Kuo

    2011-09-01

    Full Text Available Recently, the Exponentially Weighted Moving Average (EWMA controller has become a popular control method in Run-to-Run (RtR process control, but the issue of measurement noise from metrology tools has not been addressed in RtR EWMA controllers yet. This paper utilizes a Kalman Filter (KF controller to deal with measurement noise in RtR process control and investigates the output properties for steady-state mean and variance, and for closed-loop stability. Five disturbance models modeling semiconductor process disturbances are investigated. These disturbance models consist of Deterministic Trend (DT, Random Walk with Drift (RWD, Integrated Moving Average process (IMA(1,1, AutoRegressive Moving Average (ARMA(1,1, and Autoregressive Integrated Moving Average (ARIMA(1,1,1.  Analytical results show that a KF controller can be considered as an extended version of a RtR EWMA controller. In particular, the EWMA controller is a special case of KF in a filtering form without the capability of measuring noise. Simulation results also show that the KF has a better ability to deal with measurement noise than the EWMA controller.

    The effect of intestinal bacterial over-growth on brush border hydrolases and brush border glycoproteins was studied in nonoperated control rats, control rats with surgically introduced jejunal self-emptying blind loops, and rats with surgically introduced jejunal self-filling blind loops. Data were analyzed from blind loop segments, segments above and below the blind loops, and three corresponding segments in the nonoperated controls. Rats with self-filling blind loops had significantly greater fat excretion than controls and exhibited significantly lower conjugated:free bile salt ratios in all three segments. Maltase, sucrase, and lactase activities were significantly reduced in homogenates and isolated brush borders from the self-filling blind loop, but alkaline phosphatase was not affected. The relative degradation rate of homogenate and brush border glycoproteins was assessed by a double-isotope technique involving the injection of d-[6-(3)H]glucosamine 3 h and d-[U-(14)C]glucosamine 19 h before sacrifice, and recorded as a (3)H:(14)C ratio. The relative degradation rate in both homogenate and brush border fractions was significantly greater in most segments from rats with self-filling blind loops. In the upper and blind loop segments from rats with self-filling blind loops, the (3)H:(14)C ratios were higher in the brush border membrane than in the corresponding homogenates, indicating that the increased rates of degradation primarily involve membrane glycoproteins. Incorporation of d-[6-(3)H]glucosamine by brush border glycoproteins was not reduced in rats with self-filling blind loops, suggesting that glycoprotein synthesis was not affected. Polyacrylamide gel electrophoresis of brush border glycoproteins from the contaminated segments indicated that the large molecular weight glycoproteins, which include many of the surface hydrolases, were degraded most rapidly. Brush border maltase, isolated by immunoprecipitation, had (3)H:(14)C ratios characteristic of

    An examination is conducted of the Skyship 500's dynamic response to control inputs from elevators, rudders, and throttles at zero, 25, and 40 kts indicated airspeed. Input frequency sweeps were made with pitch and turn controls at 25 and 40 kts, ranging in frequency from about 0.03 to 1.5 Hz. FFT data analysis was then applied to compute describing functions for each run. Frequency responses are noted to be very smooth, and comparisons between repeat runs indicate excellent agreement. Summary plots of the faired describing functions from each run form the core of the data presented. These data constitute a comprehensive and reliable data base on which to predicate future dynamic simulation mathematical models of small airship dynamic response.

  13. An Institutional Approach to Bordering in Islands: The Canary Islands on the African-European Migration Routes

    Directory of Open Access Journals (Sweden)

    Dirk Godenau

    2012-05-01

    Full Text Available Islands play a significant role in international irregular maritime migration. Frequently they are part of maritime interstitial spaces between states, and their location, combined with institutional membership, makes them part of international migration routes and subject to border management strategies. In this paper borders are analysed as social institutions used for regulating relative permeability through rules of entry and exit for persons, goods and capital. Borders institutionalize territoriality and are politically implemented by states. They are selective, also in migration, and irregular border transit is not always indicative of an inability to control. The Canary Islands are used as an illustrative example of how border management at the southern edge of the European Union has evolved towards more coercive deterrence and tighter surveillance. The Canary Islands experienced irregular maritime immigration from the west African coasts during the first decade of the 21st century and most of these migrants intended to use the islands as transit space towards the European continent. Increasing surveillance in countries of origin, enforcement of border controls and stricter return policies were used to stop flows. The so-called “cayuco crisis” in 2006 induced institutional change in border management and forced the active involvement of the EU through FRONTEX.

  17. Hmong Across Borders or Borders Across Hmong? Social and Political Influences Upon Hmong People

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available The Hmong are a transnational ethnic people, because of their dispersal from China into Southeast Asia in the early 19th century and from Southeast Asia to Western countries from 1975 onward. However, even within the context of Southeast Asia and southern China, the Hmong are a transnational ethnic group, due to state boundaries and the enforcement of international laws.Scholars speak as though the Hmong population has crossed political and legal borders by their movement across state boundaries and international borders. However, I argue that it is the political, social, and legal borders that have cut across the Hmong people and subjected them to be citizens of different modern nation-states. Even in the present time, these borders still, and continuously, play important roles that cross and divide the Hmong people into distinctive subgroups and fragments. In this article, I will start by describing the generally understood situation of Hmong being across national borders, and then will explain my argument that borders are across the Hmong.

    Science.gov (United States)

    Konrad, V.

    2013-11-01

    Borders are increasingly complex human responses and social constructions in a world where globalizing forces confront basic human concerns for security and certainty. In an effort to provide a background to assess research directions for imaging borders, this paper explores what we know about borders, and what we do not know well about borders. Borders in globalization are the meeting points of globalizing forces of security, trade and migration flows with emerging technologies, self determination and regionalization around the world. We need to know more about how: self determination fuels secessions and new borders; borders result from complex rather than simple policy and governance issues; borders depend on the political clout of borderland communities; market and migration flows impact borders; and borders are always in motion. The paper shows how these organizing principles underlie the basic themes of border governance, flows, culture, history, security and sustainability. Finally, the paper offers two brief illustrations of border imaging to link this presentation to the following discussion of the workshop.

    Current control methods for the black carpenter ant, Camponotus pennsylvanicus (De Geer), include the use of remedial and preventative residual sprays as well as toxic baits. We evaluated the acceptance of three baits (Maxforce, Niban, and Baygon) to field colonies of the black carpenter ant in the spring and fall. Maxforce bait granules were more readily accepted than either Niban or Baygon bait granules in the spring. A change in food preference from protein to sugar by the black carpenter ant appeared to reduce the number of Maxforce bait granules removed in the fall, resulting in no differences in bait acceptability. The longevity of Dursban 50W and Tempo 20WP were evaluated in the summer and fall on painted wood panels. Panels aged outside for 15 d under prevailing weather conditions exhibited increased LT50 values. For each sampling period, panels aged on the south face (in the sun) exhibited less insecticidal activity (i.e., large LT50 values) than panels on the north face (shaded; small LT50 values). At each sampling period, Tempo 20WP provided smaller LT50 values than Dursban 50W. Because of changing dietary preferences, our data highlight the importance of using various bait types for carpenter ant control. Moreover, the application of residual spays should be made to locations protected from direct sunlight. PMID:11057723

    Science.gov (United States)

    Grant, Lisa; Proctor, Tony

    A vast amount of information relating to standards of patient care is collated from hospital wards, yet there is not always evidence that this information is discussed or acted upon by ward staff. Involving ward staff in setting up systems to monitor performance and then deciding how to address shortcomings uses their insights into care provision and gives them ownership over standards of care. The balanced scorecard is an effective tool for monitoring quality that can be applied to healthcare. This article discusses how to use it to develop and implement systems of measuring the quality of care. PMID:21410000

  17. Health at the borders: Bayesian multilevel analysis of women's malnutrition determinants in Ethiopia

    Directory of Open Access Journals (Sweden)

    Tefera Darge Delbiso

    2016-07-01

    Full Text Available Background: Women's malnutrition, particularly undernutrition, remains an important public health challenge in Ethiopia. Although various studies examined the levels and determinants of women's nutritional status, the influence of living close to an international border on women's nutrition has not been investigated. Yet, Ethiopian borders are regularly affected by conflict and refugee flows, which might ultimately impact health. Objective: To investigate the impact of living close to borders in the nutritional status of women in Ethiopia, while considering other important covariates. Design: Our analysis was based on the body mass index (BMI of 6,334 adult women aged 20–49 years, obtained from the 2011 Ethiopian Demographic and Health Survey (EDHS. A Bayesian multilevel multinomial logistic regression analysis was used to capture the clustered structure of the data and the possible correlation that may exist within and between clusters. Results: After controlling for potential confounders, women living close to borders (i.e. ≤100 km in Ethiopia were 59% more likely to be underweight (posterior odds ratio [OR]=1.59; 95% credible interval [CrI]: 1.32–1.90 than their counterparts living far from the borders. This result was robust to different choices of border delineation (i.e. ≤50, ≤75, ≤125, and ≤150 km. Women from poor families, those who have no access to improved toilets, reside in lowland areas, and are Muslim, were independently associated with underweight. In contrast, more wealth, higher education, older age, access to improved toilets, being married, and living in urban or lowlands were independently associated with overweight. Conclusions: The problem of undernutrition among women in Ethiopia is most worrisome in the border areas. Targeted interventions to improve nutritional status in these areas, such as improved access to sanitation, economic and livelihood support, are recommended.

    Neuronal ceroid lipofuscinosis (NCL) constitutes a group of recessively inherited lysosomal storage diseases that primarily affect neuronal cells. Such diseases share certain clinical and pathologic features in human beings and animals. Neuronal ceroid lipofuscinosis in Border Collie dogs was first detected in Australia in the 1980s, and the pathogenic mutation was shown to be a nonsense mutation (c.619C>T) in exon 4 in canine CLN5 gene. In the present study, novel rapid genotyping assays including polymerase chain reaction (PCR)-restriction fragment length polymorphism, PCR primer-induced restriction analysis, mutagenically separated PCR, and real-time PCR with TaqMan minor groove binder probes, were developed. The utility of microchip electrophoresis was also evaluated. Furthermore, a genotyping survey was carried out in a population of Border Collies in Japan using these assays to determine the current allele frequency in Japan, providing information to control and prevent this disease in the next stage. All assays developed in the current study are available to discriminate these genotypes, and microchip electrophoresis showed a timesaving advantage over agarose gel electrophoresis. Of all assays, real-time PCR was the most suitable for large-scale examination because of its high throughput. The genotyping survey demonstrated that the carrier frequency was 8.1%. This finding suggested that the mutant allele frequency of NCL in Border Collies is high enough in Japan that measures to control and prevent the disease would be warranted. The genotyping assays developed in the present study could contribute to the prevention of NCL in Border Collies. PMID:22362793

Borders give integrity to the inner state territory which they enclose (the role of establishing national integrity and at the same time form an outer boundary segregating the state territory from the surrounding politicial entities (the segregation role. European borders are old and reflect the political history of an old continent. The last major border changes happened after World War II. Over the centuries borders were merely lines separating one territory from another. Such borders were understood as »frontiers«. Forming an effective barrier against enemies was the overriding function of borders. Many borders were fortified and further enhanced by means of various defensive systems. In the second half of the 20th century the character of political borders changed. They became a contact area between countries, nations and cultures. Contemporary European borders reflect the colourful history of an old continent. They are predominantely functional markers: they represent the political and juridical delimitation of territories, they mark economic barriers and show their defensive nature and reveal the extent of cultural contact. As a result of European integration processes, the nature of political borders has changed: instead of division, their integration role is brought to the fore. A united Europe is nevertheless still not a borderless Europe! The borders within the »Schengen-area« have retained their political and administrative functions, it is just that the customs and security checks at the borders have been removed. During the period of European integration, borderlines were stabilized in accordance with the 1974 Helsinki Agreement. But despite this we can still observe ongoing changes to state borders, particularly in areas of conflict such as the Balkan peninsula. It seems after all that the process of demarcation

At the same time, Polish and Czech enterprises are not sufficiently mobilized to develop cross-border entrepreneurship, although a number of support instruments in this regard have been proposed. Sustainable development of the border should take into account both social and economic aspects. An important research problem therefore becomes determining the possibility of boosting the development of cross-border entrepreneurship on the basis of the existing forms of cross-border cooperation, including cooperation in the social sphere. The aim of this paper is to define the conditions and opportunities for the development of cluster cooperation in the area of cross-border entrepreneurship. The author has attempted to resolve whether the intensity of cross-border cooperation can be a factor which mobilizes companies to develop their cross-border entrepreneurship and whether cross-border entrepreneurship can be further developed within the cluster model.

    The NSF Nanomanufacturing Program supports fundamental research in novel methods and techniques for batch and continuous processes, and top-down and bottom-up processes leading to the formation of complex nanostructures, nanodevices and nanosystems. The program leverages advances in the understanding of nano-scale phenomena and processes, nanomaterials discovery, novel nanostructure architectures, innovative nanodevice and nanosystem design. It seeks to address issues such as quality, efficiency, scalability, reliability, safety and affordability. The program encourages research in the development of new nano-scale processes and production systems based on computation, modeling and simulation and use of process sensing, monitoring, and control. Research in instrumentation and metrology is an integral part of the program. Additionally, the program supports education of the next generation of researchers, and encourages building a workforce trained in nanotechnology and nanomanufacturing systems. It is also interested in understanding long-term societal implications of large-scale production and use of nano-scale materials. For this, it encourages the development of standards. This paper will describe the program philosophy.

  4. Fact and fiction in ECP measurement and control

    International Nuclear Information System (INIS)

    A review is presented of various electrochemical potentials, including the electrochemical corrosion potential, ECP, and the redox potential (Eredox) that are used in describing corrosion processes that occur in aqueous systems and for controlling and mitigating stress corrosion cracking in the primary coolant circuits of nuclear power reactors (primarily BWRs). Attention is paid to carefully defining each potential in terms of fundamental electrochemical concepts, so as to counter the confusion that has arisen amongst practitioners and theorists alike, due to the misuse of previously accepted terminology. A brief discussion is also included of reference electrodes and it is shown that the use of a platinum redox sensor as a reference electrode in the monitoring of ECP in BWR primary coolant circuits is inappropriate unless it is demonstrated to yield a potential that is invariant with changes in the composition of the medium. Data from laboratory experiments in simulated BWR coolant and model calculations argue that the potential of the Pt redox sensor is not invariant with respect to composition under the conditions that exist in BWR pressure vessels and hence the use of a Pt sensor as a reference electrode is inappropriate.

  5. A Proposal for a Mist Cooling Control and Measurement Methods

    Science.gov (United States)

    Farnham, Craig; Nakao, Masaki; Nishioka, Masatoshi; Nabeshima, Minako; Mizuno, Takeo

    Fine water mist sprays with average droplet diameters around 20 microns are being increasingly used as an energy-efficient means of cooling outdoor and semi-enclosed spaces such as rail platforms and shopping arcades. At high relative humidity there is a higher risk of wetting people and the ground beneath mist nozzles. Automated control systems are often set to run above a set dry bulb temperature and below a set relative humidity. Experiments show that mist evaporation rates before reaching the ground are closely related to the difference between the dry bulb and wet bulb temperatures, here labeled ΔTWB. Changing the operating parameters to include a minimum ΔTWB can allow use at higher relative humidity levels. If a common 28°C, 70% condition is sufficient to prevent floor-wetting, then a condition of 28°C with a ΔTWB > 4.3K should still prevent floor-wetting. This would allow operation at 75% relative humidity near 39°C.

  6. Europe: history, current situation and control measures for infectious bronchitis

    Directory of Open Access Journals (Sweden)

    2010-06-01

    Full Text Available The emergence and nature of different strains of infectious bronchitis virus (IBV in Europe are described. Infectious bronchitis (IB is the most important endemic viral respiratory disease where highly pathogenic Newcastle disease and avian influenza are not present. IB was first described in the UK in 1948 and identified as Massachusetts type. In the 1970s and 80s new serotypes were reported in Holland and elsewhere and new vaccines were developed. The 1990s saw the emergence of the major variant commonly called 793B, again needing a new vaccine. Two novel types have been recognised since 2000, Italy 02 and QX. Italy 02 appears to be well controlled by the use of two different live vaccines (H120 and the 793B-related 4/91 while for QX, associated with nephritis in young birds and silent layers, new vaccines are in development. The use of two vaccines as above is a widely used protocol and is capable of protecting against a wide range of different types. Alternative approaches to IB vaccination are discussed. The importance of constant surveillance for prevalent and novel IBV types is emphasised and the value of experimental infections in chickens to determine the pathogenesis and pathology of new types in addition to testing efficacy of vaccines is outlined.

    Full Text Available The special clustering algorithm is attractive for the task of grouping arbitrary shaped database into several proper classes. Up to now, a wide variety of clustering algorithms designed for this task have been proposed, the majority of these algorithms is density-based. But the effectivity and efficiency still is the great challenges for these algorithms as far as the clustering quality of such task is concerned. In this paper, we propose an arbitrary shaped clustering method with border grids (PNMBG, PNMBG is a crisp partition method. It groups objects to point neighborhoods firstly, and then iteratively merges these point neighborhoods into clusters via grids, only bordering grids are considered during the merging stage. Experiments show that PNMBG has a good efficiency especially on the database with high dimension. In general, PNMBG outperforms DBSCAN in the term of efficiency and has an almost same effectivity with the later.

    2012-10-01

    A two-year old, male entire Border collie was presented with a one-year history of exercise-induced collapsing on the pelvic limbs. Physical examination revealed generalised muscle atrophy. Neurological examination supported a generalised neuromuscular disorder. Electromyography revealed spontaneous electrical activity in almost all muscles. Unfixed and formaldehyde-fixed biopsy samples were collected from the triceps brachii, longissimus and vastus lateralis muscles. Histopathological, histochemical and ultrastructural examinations of biopsy specimens were consistent with either centronuclear or myotubular myopathy. The dog clinically improved with supportive treatment with L-carnitine, co-enzyme Q10 and vitamin B compound. To the authors' knowledge, this is the first report of centronuclear/myotubular myopathy in a Border collie. PMID:23013377

    Five Border Collie dogs with ceroid-lipofuscinosis developed progressive neurological disease between 18 and 22 months of age. These dogs had behavioural abnormalities, gait and visual deficits and became progressively demented. All dogs examined had common ancestors. Light microscopic examination of tissues demonstrated extensive accumulation of granular, sudan black-staining autofluorescent material in the cytoplasm of neurones, retinal ganglion cells and some visceral cells. At ultrastructural examination inclusions of variable morphology were observed. PMID:3376765

    Territorial subdivisions and geographic borders are essential for understanding phenomena in sociology, political science, history, and economics. They influence the interregional flow of information and cross-border trade and affect the diffusion of innovation and technology. However, it is unclear if existing administrative subdivisions that typically evolved decades ago still reflect the most plausible organizational structure of today. The complexity of modern human communication, the ease of long-distance movement, and increased interaction across political borders complicate the operational definition and assessment of geographic borders that optimally reflect the multi-scale nature of today's human connectivity patterns. What border structures emerge directly from the interplay of scales in human interactions is an open question. Based on a massive proxy dataset, we analyze a multi-scale human mobility network and compute effective geographic borders inherent to human mobility patterns in the United States. We propose two computational techniques for extracting these borders and for quantifying their strength. We find that effective borders only partially overlap with existing administrative borders, and show that some of the strongest mobility borders exist in unexpected regions. We show that the observed structures cannot be generated by gravity models for human traffic. Finally, we introduce the concept of link significance that clarifies the observed structure of effective borders. Our approach represents a novel type of quantitative, comparative analysis framework for spatially embedded multi-scale interaction networks in general and may yield important insight into a multitude of spatiotemporal phenomena generated by human activity.

    2012-06-01

    Wireless sensor networks (WSNs) have emerged as means of providing automated monitoring, target tracking, and intrusion detection. Solar-powered WSNs that adopt innovative sensors with low power consumption and forefront networking technologies can provide rapidly deployable situational awareness and effective security control at the border at low cost. In our paper, we introduce the prototype of our new solar-powered WSN platform for Border Security. We consider practical issues in WSNs, including sensing environment classification, survivability under harsh weather conditions, and efficient solar energy harvesting. Experimental results demonstrate the performance of our new solar-powered WSN.

    The article deals with the new opportunities for EU member state citizens to go abroad for medical treatment. The European Court of Justice has facilitated the access to medical treatment for EU citizens in other EU states. This development has worried national governments since they feared reduced control in their healthcare systems. The cross-border project "healthacross" between Austria and the Czech Republic however illustrates in which way authorities can respond to patients needs in two different countries. Nevertheless a plethora of administrative and practical problems have to be solved for cross-border co-operation in the provision of healthcare. PMID:21391444

    2011-03-01

    Full Text Available The aim of this special issue is to address the evolution of European borders from a comparative perspective. This collection of papers spans a wide variety of topics in the realm of borderland studies. Although each engages with a single empirical or theoretical case collectively they identify nuances relevant to the theoretical elaboration of borders, and particularly contribute to the field of sub-national cross-border cooperation. In the course of its analysis each paper contributes to a broader understanding of the definition of cross-border regions; identifies a set of barriers to cooperation in these contexts; explores the role of identities on cooperation and of the role of borders in constructing those identities; and reflects on the socio-political meanings and uses of these international boundaries. This introduction discusses theoretical significance of these contributions to major debates in the study of borders and border regions.

  3. Left ventricular border recognition using a dynamic search algorithm

    International Nuclear Information System (INIS)

    Initial results obtained with a simple, fully automated algorithm for detection of left ventricular boundaries are presented. The strength of this approach is the use of dynamic programming search techniques, which allow determination of local border points to be influenced by the entire global border location. The relative contributions of mask mode subtraction and the dynamic search technique are evaluated with respect to accurate border definition. These computer-determined ventricular borders are compared with hand-traced borders on subtracted and unsubtracted images. The modular dynamic search algorithm is shown to perform better than previously described algorithms, which generally require operator interaction. It is also shown that for both manual and automated techniques, ventricular borders derived from subtracted images may be significantly different from borders derived from nonsubtracted images

  4. Attitude Estimation and Position Control of VTOL UAVs using IMU and GPS Measurements

    CERN Document Server

    Roberts, Andrew

    2011-01-01

    We address two fundamental problems associated with the control of vertical take-off and landing (VTOL) unmanned airborne vehicles (UAVs): attitude estimation and position control. We propose two velocity-aided attitude observers which utilize a global-positioning system (GPS) in addition to an inertial measurement unit (IMU). The `velocity-aided' class of observer uses an accelerometer to measure the system \\emph{apparent acceleration} (instead of the gravity vector), and is therefore better suited for applications where the rigid-body (aircraft) is subjected to significant linear accelerations (which is to be expected for VTOL UAVs). We also propose a position controller which utilizes the accelerometer in a similar fashion. More precisely, rather than using the system orientation (as is usually done in the existing position controllers), we use the vector measurements (accelerometer and magnetometer measurements) directly in the position control law. Consequently, the proposed position controller does not ...

    2012-01-01

    Full Text Available Borders and border areas require security measures, which are very important to create security on the borders. The paper also analyzes the role of ethnic groups living near borderlines. Iran is an ethnically varied country and distinguishing characteristics of ethnic groups from each other in Iran is particularly concentrated on language, religion and ethnic components. These ethnic groups have been scattered as certain minority groups in border provinces and areas. The presence of Iranian nationals in the Western, Eastern and Northern borders which are contiguous with countries with the same religion and language creates by itself an appropriate context for the occurrence of ethnic crises in border areas and boundary underdevelopment is an another cause for this problem. In addition, the three components, namely religion, ethnicity, and language, should be taken into consideration in adopting policies and strategies to deal with these areas. In Sistan and Baluchestan, Iran, there are effective national strategies taking advantage of the presence and existence of religious and ethnic groups in the border towns, adopting security and development policies taking into account these two issues. They have a deep effect on regional development and national solidarity due to construction activities and infrastructure investments on the one hand and reducing insecurity and trafficking on the other hand.

    One of the world’s leading problems in the field of national security is protection of borders and borderlands. This book addresses multiple issues on advanced innovative methods of multi-level control of both ground (UGVs) and aerial drones (UAVs). Those objects combined with innovative algorithms become autonomous objects capable of patrolling chosen borderland areas by themselves and automatically inform the operator of the system about potential place of detection of a specific incident. This is achieved by using sophisticated methods of generation of non-collision trajectory for those types of objects and enabling automatic integration of both ground and aerial unmanned vehicles. The topics included in this book also cover presentation of complete information and communication technology (ICT) systems capable of control, observation and detection of various types of incidents and threats. This book is a valuable source of information for constructors and developers of such solutions for uniformed servi...

  9. Civic Stratification and the Exclusion of Undocumented Immigrants from Cross-border Health Care.

    Torres, Jacqueline M; Waldinger, Roger

    2015-12-01

    This paper proposes a theoretical framework and an empirical example of the relationship between the civic stratification of immigrants in the United States, and their access to healthcare. We use the 2007 Pew Hispanic Center/Robert Wood Johnson Foundation Hispanic Healthcare Survey, a nationally representative survey of U.S. Latinos (N = 2,783 foreign-born respondents) and find that immigrants who are not citizens or legal permanent residents are significantly more likely to be excluded from care in both the United States and across borders. Legal-status differences in cross-border care utilization persisted after controlling for health status, insurance coverage, and other potential demographic and socioeconomic predictors of care. Exclusion from care on both sides of the border was associated with reduced rates of receiving timely preventive services. Civic stratification, and political determinants broadly speaking, should be considered alongside social determinants of population health and health care. PMID:26582512

  10. Examining hidden coercion at state borders: why carrier sanctions cannot be justified

    Directory of Open Access Journals (Sweden)

    Tendayi Bloom

    2014-05-01

    Full Text Available Sanctions placed upon airlines and other operators transporting persons without the required paperwork are called ‘carrier sanctions’. They constitute a key example of how border control mechanisms are currently being outsourced, privatized, delegated, and moved from the border itself to new physical locations. These practices can lead to a phenomenon referred to in this paper as ‘hidden coercion’. This paper argues that, while hidden coercion is commonplace in the reality of migration policy in most states, it is so far neglected in theoretical discussions of state coercion. Moreover, the discussion of carrier sanctions demonstrates that this neglect is problematic, since hidden coercion is not justifiable even within a framework that legitimizes state border coercion.

  12. Rush to the border? Market liberalization and urban- and rural-origin internal migration in Mexico.

    Science.gov (United States)

    Villarreal, Andrés; Hamilton, Erin R

    2012-09-01

    In this study we examine the social and economic factors driving internal migration flows in Mexico. We pay particular attention to the effect that economic liberalization has had in encouraging migration to border cities. Our analysis of the origin and destination of migrants is carried out at a finer level of geographical detail than ever before. Microdata files from the 2000 population census allow us to distinguish urban- and rural-origin migrants to the largest 115 cities and metropolitan areas in the country. Our results indicate that economic liberalization, measured by the level of foreign investment and employment in the maquiladora export industry, strongly influences migrants' choice of destinations. However, economic liberalization fails to fully account for the attraction of the border, as do the higher emigration rates to the United States from border cities. Our analysis also reveals that migrants to the border region and to cities with high levels of foreign investment are younger, less educated and more likely to be men than migrants to other parts of Mexico. Rural migrants are significantly more likely to move to the border and to cities with high levels of foreign investment than urban migrants. The results of our study have important implication for other countries opening their economies to foreign investment and international trade.

  13. Improving Control System Cyber-State Awareness using Known Secure Sensor Measurements

    Energy Technology Data Exchange (ETDEWEB)

    Ondrej Linda; Milos Manic; Miles McQueen

    2012-09-01

    Abstract—This paper presents design and simulation of a low cost and low false alarm rate method for improved cyber-state awareness of critical control systems - the Known Secure Sensor Measurements (KSSM) method. The KSSM concept relies on physical measurements to detect malicious falsification of the control systems state. The KSSM method can be incrementally integrated with already installed control systems for enhanced resilience. This paper reviews the previously developed theoretical KSSM concept and then describes a simulation of the KSSM system. A simulated control system network is integrated with the KSSM components. The effectiveness of detection of various intrusion scenarios is demonstrated on several control system network topologies.

    2014-05-01

    Hypertension is a growing public health problem for U.S.-Mexico border Latinos, who commonly experience low levels of awareness, treatment, and control. We report on a process evaluation that assessed the delivery of Corazón por la Vida, a 9-week promotora de salud-led curriculum to help Latinos manage and reduce hypertension risks in two rural/frontier counties in the New Mexico border region. Ninety-six adults participated in the program, delivered in three waves and in three communities. We assessed program delivery and quality, adherence, exposure, and participant responsiveness. Participant outcome measures included self-reported eating and physical activities and assessment of community resources. Findings suggest that the program was fully delivered (99%) and that most participants (81.7%) were very satisfied with the educational sessions. The average participant attendance for educational sessions was 77.47%. We found significant differences in self-reported behavioral changes depending on the number of sessions completed: The higher the dose of sessions, the better the self-reported outcomes. These findings suggest that a promotora-led curriculum may be useful for promoting self-management of chronic disease in rural/frontier border Latino populations. Future evaluation should focus on training and implementation adaptations within evidence-based chronic disease programs for diverse Latino communities.

    2009-01-01

    Traditional linear time-invariant (LTI) control design assumes that measurements are taken at regular time intervals and have independent additive noise. A common practical case that violates this assumption is the use of encoders that give quantized position measurements; when the quantization is appreciable the measurement noise is far from LTI. This paper develops a simple event-based controller based on simplifying a joint maximum a posteriori estimator, which is a...

    Cross-border cooperation to promote economic development and political integration has been among the EU’s key themes since the 1990s, and contemporary policy networks are considered useful organisational solutions. Focusing on transport policies in the border regions of Basel and Luxembourg, we...... analyse measures of persistency of national preferences among policy actors, mapping their perceived ‘policy spaces of action’ and conceptualising these policy spaces as relational. We discuss two empirical findings: The networks’ various actors on either side of the border appear to perceive the actual...... ‘policy spaces’ very differently. Therefore, and due to the networks’ terminability, these policy spaces are highly contested and frequently negotiated between the actors. Based on a combination of in-depth interviews, sketch maps, and social network analysis, we show that large spatiocultural differences...

  1. Border detection on Common Carotid Artery using Gauss-Markov Estimation

    Koya, Yoshiharu; Mizoshiri, Isao

    The arteriosclerosis is on the increase with an aging or change of our living environment. For that reason, diagnosis of the common carotid artery using echocardiogram is doing to take precautions carebropathy. The arteriosclerosis of the common carotid artery is diagnosed using Intima-Media Thickness (IMT) which is obtained from echocardiogram. In order to measure IMT from echocardiogram, it is required to detect a border which is a boundary between vessel tissue layers. The method of border detection requires reproducibility, high accuracy and high-speed. In this paper, we propose the high-accuracy and high-speed detection method by Gauss-Markov estimation. About high-accuracy, it realized by attaching importance to high reliable candidate point of border. And, about high-speed, it realized by calculating matrix only one time.

    Ambient air measurements collected from 1994 to 1995 were used in a preliminary assessment of potential source and spatial influences in the Ambos Nogales border region (Nogales, Arizona, USA and Nogales, Sonora, Mexico). In this assessment, volatile organic compounds (VOC) and particulate matter (PM) species were used from four sites, two on either side of the border. An examination of median levels and principal component analysis indicated the dominance of soil dusts and mobile sources. Pairwise comparisons of sites for VOCs associated with mobile sources revealed statistically significant differences between sites in the central Nogales area vs. the two sites furthest from the border. Particulate lead at Mexican sites was higher and significantly different vs. US sites. Although further analyses are necessary, findings suggest that local and immediate mobile/other anthropogenic and soil dust influences are present throughout Nogales, with particulate lead from leaded motor vehicle exhaust or soldering operations being a possible influence on the Mexican side.

    2012-12-01

    Full Text Available This study discusses the socially and culturally constructed Finnish-Russian border which has been developed as a lifelong process, in the context of modern elderly Finns. It focuses on the emotions of fear represented in life and historically contextualised narratives discussing the post-war period in eastern borderlands. The included texts concentrate on border issues and are mainly based on the writer’s personal experiences. The analysis is based on oral history methodology and highlights mainly the represented personal interpretations of the past, rather than actual historical events. The concept of fear is used as a theoretical tool to interpret the expressions of emotions in narrated memories. The study seeks to illustrate the causes of fear on the Finnish-Russian border in peacetime contemporary Finland.

    Political borders are controversial and contested spaces. In an attempt to better understand movement along and through political borders, this project applied the metaphor of a membrane to look at how people, ideas, and things ''move'' through a border. More specifically, the research team employed this metaphor in a system dynamics framework to construct a computer model to assess legal and illegal migration on the US-Mexico border. Employing a metaphor can be helpful, as it was in this project, to gain different perspectives on a complex system. In addition to the metaphor, the multidisciplinary team utilized an array of methods to gather data including traditional literature searches, an experts workshop, a focus group, interviews, and culling expertise from the individuals on the research team. Results from the qualitative efforts revealed strong social as well as economic drivers that motivate individuals to cross the border legally. Based on the information gathered, the team concluded that legal migration dynamics were of a scope we did not want to consider hence, available demographic models sufficiently capture migration at the local level. Results from both the quantitative and qualitative data searches were used to modify a 1977 border model to demonstrate the dynamic nature of illegal migration. Model runs reveal that current US-policies based on neo-classic economic theory have proven ineffective in curbing illegal migration, and that proposed enforcement policies are also likely to be ineffective. We suggest, based on model results, that improvement in economic conditions within Mexico may have the biggest impact on illegal migration to the U.S. The modeling also supports the views expressed in the current literature suggesting that demographic and economic changes within Mexico are likely to slow illegal migration by 2060 with no special interventions made by either government.

    According to the charge variation of output capacitor in a switching cycle, the output voltage variation in a switching cycle can be obtained, from which an approximate discrete-time model of pulse train (PT) controlled buck converter operating in discontinuous conduction mode (DCM) is established. Based on the model, the border-collision bifurcations of the PT controlled DCM buck converter with the variations of the load resistance and the input voltage are studied. By constructing the corresponding iterative map curves, the stabilities of the fixed points, formed by the orbits of period-l, period-2, period-3 and so on, are analyzed, and the mechanisms of border-collision bifurcations of the converter under different operation states are revealed. The analysis results indicate that with the variation of parameters, the PT controlled DCM buck converter always operates in different periodic states, in which the change of the operation mode with periodic state is caused by the border-collision bifurcation and the lyapunov exponent is always less than zero. By using PSIM circuit simulation software, the time domain waveforms and phase portraits under different load resistances are obtained. Experimental results are provided to verify the correctnesses of theoretical analyses and circuit simulations and the feasibility of dynamical modelling.%通过建立一个开关周期内输出电容电荷变化量对应的输出电压变化量,建立了工作于电感电流断续模式(discontinuousconductionmode,DCM)的脉冲序列(pulsetrain,VT)控制Buck变换器的近似离散时间模型,研究了负载电阻及输入电压变化时PT控制DCMBuck变换器的边界碰撞分岔行为.通过构造相应的迭代映射曲线,分别分析了不同负载电阻时阿控制DCMBuck变换器的周期1、周期2和周期3运行轨迹的不动点稳定性,揭示了PT控制DCMBuck变换器在不同周期态时的边界碰撞分岔的形成机理.研究结

    Full Text Available Although literature and poetry have numerous borders of their own,these are rarely assumed to have any significance for the world out-side the text itself. A number of reasons for this distinctive division certainly stem from the literary field itself. This paper intends to indicate the exclusivist stance of some theories of literature, and the inclucivist of others, before exploring the possibilities of bridging between borders in text and territory by reference to the life and literature of Oscar Wilde and a performative and imaginative analysis of Paul Muldoon's epigrammatic poem The Plot.

    At the end of the year 2006, France proposed the introduction of a 'climatic tariff' into the discussion of the international climatic protection. The 'climatic tariff' shall adjust extra costs, which result from the domestic production by means of environmental protection instruments and to which the import goods are not exposed, with import/export compensatory payments in the form of import duties and/or taxes on import goods. The introduction of an import/export compensatory payment system aims to load imported goods equivalent to domestic products in order to adjust competitive disadvantages. In the contribution under consideration the authors report on possibilities and problems of design for an import/export tax compensatory. The authors examine the validity of the measures of import/export compensation from legal view the World Trade Organization (Geneva, Switzerland) based on the General Agreement on Tariffs and Trade.

    Full Text Available Measurement error is the difference between the true value and the measured value of a quantity that exists in practice and may considerably affect the performance of control charts in some cases. Measurement error variability has uncertainty which can be from several sources. In this paper, we have studied the effect of these sources of variability on the power characteristics of control chart and obtained the values of average run length (ARL for zero-truncated Poisson distribution (ZTPD. Expression of the power of control chart for variable sample size under standardized normal variate for ZTPD is also derived.

    An in situ measuring technique for use in automated composite processing and quality control is discussed. Frequency dependent electromagnetic sensors are used to measure processing parameters at four ply positions inside a thick section 192-ply graphite-epoxy composite during cure in an 8 x 4 in. autoclave. Viscosity measurements obtained using the sensors are compared with the viscosities calculated using the Loos-Springer cure process model. Good overall agreement is obtained. In a subsequent autoclave run, the output from the four sensors was used to control the autoclave temperature. Using the 'closed loop' sensor controlled autoclave temperature resulted in a more uniform and more rapid cure cycle.

    Control configuration selection is the procedure of choosing the appropriate input and output pairs for the design of SISO (or block) controllers. This step is an important prerequisite for a successful industrial control strategy. In industrial practices it is often the case that systems, which...... are needed to be controlled, are nonlinear and linear models are insufficient to describe the behavior of the processes. The focus of this paper is on the problem of control configuration selection for a class of nonlinear systems which is known as bilinear systems. A gramian-based interaction measure...... for control configuration selection of MIMO bilinear processes is described. In general, most of the results on the control configuration selection, which have been proposed so far, can only support linear systems. The proposed gramian-based interaction measure not only supports bilinear processes but also...

    Full Text Available The article investigates the challenging task of governing cross-border investment in peripheral regions. The main objective is to identify common opportunities and obstacles in the Pomerania Euroregion by taking the case study of Polish citizens/ entrepreneurs investing in northeast Germany. This relatively new phenomenon is accompanied by large uncertainties and risks, and lacks further empirical insights. At the same time it breaks new ground, creates alternatives, calls for the development of efficient modes of cross-border cooperation and addresses mutual governance issues on an inter-regional basis between manifold stakeholders on both sides of the border. The case study summarises findings from fieldwork, elaborates a quantitative and qualitative assessment of cross-border governance measures within formal and informal institutions, and tries to formulate policy recommendations for prospective approaches

    We model simultaneous inter and within identity-group conflict in two territories connected by cross-territorial spill-overs. Within each territory, two groups contest the division of a group-specific public good, and all members contest the division of group income. Each group has a cross-border affiliate. Greater success (share) of its affiliate 'spills over' into higher efficiency of a group in inter-group conflict. We find that inter-group and total conflict move together within a territo...

  19. Cross-Border Landscape: Construction of Natural Heritage and Local Development at Bulgarian-Serbian Borderlands

    2015-08-01

    Full Text Available Normally nature is examined as a phenomenon which is subject to natural laws; it belongs to the field of natural sciences. In constructivist perspective the environment is subsumed under the symbolism of humans’ tradition and culture. From such point of view the very notion of nature is unthinkable without taking into account its existence and understanding in a specific social, economic and cultural context of definite time, space and society. In the proposed paper I proceed from this paradigm in examination of a definite natural landscape which, however, is divided by the political border. The research attention is focused on a region of Bulgarian-Serbian borderlands – the area where the Erma River flows. The river takes its sources in Serbia and though it is not very long, it is notable for passing the Bulgarian-Serbian border twice, and for its two remarkable gorges – the Gorge of Tran in Bulgaria and the Gorge of Poganovo in Serbia. During the socialist period this border region was under strong military and police control. The crossing of the border was formally impossible; the borderlands remained peripheral industrially undeveloped areas and were putted under strong depopulation. However, the lands on either side of the border preserved its pristine nature. During the last two decades the preserved natural landscape and certain nature objects have been turned into more important landmarks and included in the value scale of local communities as symbols and heritage. In result, the above mentioned gorges have become more important part of strategic priorities in the local policies of revival of these economically undeveloped borderlands in the Western Bulgaria and Eastern Serbia. Nowadays the local efforts are uniting through different joint cross-border projects and activities in the sphere of nature preservation and eco-tourism.
