  1. Avoiding the Haircut: Potential Ways to Enhance the Value of theUSDA's Section 9006 Program

    Energy Technology Data Exchange (ETDEWEB)

    Bolinger, Mark

    2006-07-13

    Section 9006 of Title IX of The Farm Security and Rural Investment Act of 2002 (the '2002 Farm Bill') established the Renewable Energy Systems and Energy Efficiency Improvements Program (the 'Section 9006 program'). Administered by the United States Department of Agriculture (USDA), the Section 9006 program provides grants, loan guarantees, and - perhaps in the future - direct loans to farmers, ranchers, and rural small businesses for assistance with purchasing renewable energy systems and making energy efficiency improvements. In the three rounds of Section 9006 funding to date (FY03-FY05), roughly 40% of all grant dollars in aggregate have been awarded to 'large' (defined as > 100 kW) wind projects. Such projects are also typically eligible for the Federal Production Tax Credit (PTC) codified in Section 45 of the US tax code. Because the PTC provides a significant amount of value to a wind project, most 'large wind' applicants to the Section 9006 program have also tried to take advantage of the PTC. Through what are known as 'anti-double-dipping' or, more colloquially, 'haircut' provisions, however, the size of the PTC is reduced if a project receives certain other forms of governmental support. Specifically, Section 45(b)(3) of the US tax code reduces the size of the PTC in proportion to the aggregate amount of government grants, tax-exempt or subsidized financing, or other Federal tax credits that a project receives over time, relative to its overall capital cost (with the proportion not to exceed 50%). The legislative and regulatory history surrounding the PTC's haircut provisions suggests that grants and direct loans (but not loan guarantees) provided under the Section 9006 program will cause a PTC haircut. Focusing exclusively on 'large wind' projects, this report demonstrates that the magnitude of the haircut can be significant: Section 9006 grants lose between 11% and 46% of their

  3. Health risks of the clean-shave chiskop haircut.

    The clean-shave haircut known locally as the chiskop is rare among females but popular with black South African men, who are also predisposed to folliculitis keloidalis nuchae (FKN) (keloids on the back of the head). During a previous study, participants described an unexpected symptom of haircut-associated bleeding. As this is not a widely recognised entity, we conducted the present study at an HIV clinic servicing the same population, with the objective of comparing the prevalences of haircut-associated bleeding and FKN in 390 HIV-positive subjects with published data for Langa (Western Cape, South Africa). The results for HIV-positive participants were similar to the population data, but in both groups the prevalence of haircut-associated bleeding (24.5% v. 32%; p=0.17) was much higher than that of FKN (10.2% v. 10.5%), suggesting that the hairstyle increases the risk of bleeding even in people with healthy scalps without folliculitis. This study does not (and was not intended to) prove a higher HIV prevalence in chiskop wearers or in FKN sufferers, but it confirms a history of haircut-associated bleeding in at least a quarter of our male study participants. The risk of transmission of blood-borne infection via haircuts is likely to be low, but requires formal quantification. Public education on adequate sterilisation of barber equipment between haircuts and promotion of individual hair-clipper ownership for chiskop clients should not be delayed. Depilatory creams formulated for African hair offer a non-mechanical means of achieving clean-shave hairstyles.

  5. Constraining the Milky Way potential using the dynamical kinematic substructures

    Full Text Available We present a method to constrain the potential of the non-axisymmetric components of the Galaxy using the kinematics of stars in the solar neighborhood. The basic premise is that dynamical substructures in phase-space (i.e. due to the bar and/or spiral arms are associated with families of periodic or irregular orbits, which may be easily identified in orbital frequency space. We use the “observed” positions and velocities of stars as initial conditions for orbital integrations in a variety of gravitational potentials. We then compute their characteristic frequencies, and study the structure present in the frequency maps. We find that the distribution of dynamical substructures in velocity- and frequency-space is best preserved when the integrations are performed in the “true” gravitational potential.

    2003-01-01

    Reported rates of autism have increased sharply in the United States and the United Kingdom. One possible factor underlying these increases is increased exposure to mercury through thimerosal-containing vaccines, but vaccine exposures need to be evaluated in the context of cumulative exposures during gestation and early infancy. Differential rates of postnatal mercury elimination may explain why similar gestational and infant exposures produce variable neurological effects. First baby haircut samples were obtained from 94 children diagnosed with autism using Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM IV) criteria and 45 age- and gender-matched controls. Information on diet, dental amalgam fillings, vaccine history, Rho D immunoglobulin administration, and autism symptom severity was collected through a maternal survey questionnaire and clinical observation. Hair mercury levels in the autistic group were 0.47 ppm versus 3.63 ppm in controls, a significant difference. The mothers in the autistic group had significantly higher levels of mercury exposure through Rho D immunoglobulin injections and amalgam fillings than control mothers. Within the autistic group, hair mercury levels varied significantly across mildly, moderately, and severely autistic children, with mean group levels of 0.79, 0.46, and 0.21 ppm, respectively. Hair mercury levels among controls were significantly correlated with the number of the mothers' amalgam fillings and their fish consumption as well as exposure to mercury through childhood vaccines, correlations that were absent in the autistic group. Hair excretion patterns among autistic infants were significantly reduced relative to control. These data cast doubt on the efficacy of traditional hair analysis as a measure of total mercury exposure in a subset of the population. In light of the biological plausibility of mercury's role in neurodevelopmental disorders, the present study provides further insight into one

    Full Text Available In this work we aimed to identify some ways of increasing the recovery of the tourism potential of the historical region Crisan. Given the multitude of economic implications, socio-cultural and environmental impacts of rural tourism by increasing recovery tourist potential, the positive impact of this economic activity will be felt by all concerned: residents, entrepreneurs, tourists and local public administration. By the way, tourists will benefit a greater diversity of services for accommodation, dining and leisure, causing them to disseminate their opinions among other tourists and even return to those places.

    The search for novel anti-hepatocellular carcinoma (HCC) agents is important. Mammalian target of rapamycin (mTOR) hyper-activation plays a pivotal role in promoting HCC tumorigenesis and chemoresistance. The current preclinical study evaluated the potential anti-HCC activity by a potent mTOR kinase inhibitor, WAY-600. We showed that WAY-600 inhibited survival and proliferation of HCC cell lines (HepG2 and Huh7) and primary human HCC cells. Caspase-dependent apoptosis was activated by WAY-600 in above HCC cells. Reversely, caspase inhibitors largely attenuated WAY-600's lethality against HCC cells. At the signaling level, WAY-600 blocked mTOR complex 1/2 (mTORC1/2) assemble and activation, yet activated MEK-ERK pathway in HCC cells. MEK-ERK inhibitors, PD-98059 and MEK-162, or MEK1/2 shRNA significantly potentiated WAY-600's cytotoxicity in HCC cells. Further studies showed that WAY-600 intraperitoneal (i.p.) administration in nude mice inhibited p-AKT Ser-473 and displayed significant anti-cancer activity against HepG2 xenografts. Remarkably, co-administration of MEK-162 further potentiated WAY-600's anti-HCC activity in vivo. These preclinical results demonstrate the potent anti-HCC activity by WAY-600, either alone or with MEK-ERK inhibitors. -- Highlights: •WAY-600 inhibits HCC cell survival and proliferation in vitro. •WAY-600 activates caspase-dependent apoptosis in HCC cells. •WAY-600 blocks mTORC1/2 activation, but activates MEK-ERK in HCC cells. •MEK-ERK inhibitors or MEK1/2 shRNA enhances WAY-600's cytotoxicity against HCC cells. •MEK-162 co-administration potentiates WAY-600-induced the anti-HepG2 tumor efficacy.

    Full Text Available Teaching English for non English Department students will be quite a challenge as the students have various background and interest. Handling those students in a big number in a class that requires them to speak is another impending challenge. This is an action research on role-play in English classroom for Information Technology students. This study tries to see whether recorded-role play could maximize students‘ potential in speaking. This study involved 30 students taking English course in Information Technology Faculty. The students were given a situation in which they had to act the role play. They drafted the role -play before they recorded it. The result shows that students felt less tense in acting the role. They also got more time to practice their pronunciation before recording. It even gave students who felt reluctant and shy in the class to actively participate. In addition, students could play around with the supporting background sound to show their creativity. Surprisingly, most students do their best to show their effort in their speaking as the end-product would be played in the classroom, even the most quiet students performed really well. Finally, this recorded-role play proved to be an effective way to maximize students‘ potential in speaking.

  10. Metabolomics: A potential way to know the role of vitamin D on multiple sclerosis.

    Science.gov (United States)

    Luque-Córdoba, Diego; Luque de Castro, María D

    2017-03-20

    The literature about the influence of vitamin D on multiple sclerosis (MS) is very controversial, possibly as a result of the way through which the research on the subject has been conducted. The studies developed so far have been focused exclusively on gene expression: the effect of a given vitamin D metabolite on target receptors. The influence of the vitamin D status (either natural or after supplementation) on MS has been studied by measurement of the 25 monohydroxylated metabolite (also known as circulating form), despite the 1,25 dihydroxylated metabolite is considered the active form. In the light of the multiple metabolic pathways in which both forms of vitamin D (D2 and D3) are involved, monitoring of the metabolites is crucial to know the activity of the target enzymes as a function of both the state of the MS patient and the clinical treatment applied. The study of metabolomics aspects is here proposed to clarify the present controversy. In "omics" terms, our proposal is to take profit from up-stream information-thus is, from metabolomics to genomics-with a potential subsequent step to systems biology, if required.

    Taylor, Kay Ann; Robinson, Daniel C

    2009-01-01

    Women now dominate student enrollment in colleges of veterinary medicine in the USA, as well as in other countries. Projections indicate that this will remain a constant. The implications for teaching, learning, mentoring, leadership, professional development, student and faculty diversity, and curriculum structure are enormous. This article provides the groundwork for examining gender diversity in veterinary medical education. Women's development and ways of knowing are identified as paramount for understanding and benefiting students and faculty in their higher education experiences and in their professional lives. Seminal research focusing on women's development and ways of knowing is introduced, summarized, and contrasted to male-centered models, and implications for teaching practice are considered. Our underlying premise is that research about women's moral and intellectual development is relevant to veterinary education and supports the adoption of student-centered approaches to teaching and learning.

    Resting atop a deep marine basin, the West Antarctic Ice Sheet has long been considered prone to instability. Using a numerical model, we investigated the sensitivity of Thwaites Glacier to ocean melt and whether its unstable retreat is already under way. Our model reproduces observed losses when forced with ocean melt comparable to estimates. Simulated losses are moderate (1 mm per year of sea-level rise) collapse in the different simulations within the range of 200 to 900 years.

    Directory of Open Access Journals (Sweden)

    Brunelle Thierry

    2017-01-01

    Full Text Available This paper reviews the potential and barriers of demand-side mitigation options in the agricultural sector based on the recent academic literature and on a survey conducted on a sample of 788 respondents living in France. The mitigation potential of such measures as reducing losses in the food supply chain and shifting diets toward less animal products is estimated to be particularly high, higher, in particular, than supply-side mitigation options. However, to ensure that these measures do not entail a reduction in protein intake, these estimations should consider both caloric and protein units, and take into account the digestibility differentials between protein sources. Our survey shows that people are relatively reluctant to eat more sustainably, preferring to reduce their emissions in other areas such as housing or equipment. This relative reluctance is mainly due to individual perceptions linked to health concerns, taste or habits. Some obstacles could easily be overcome through well-designed policies aiming to, for example, advertise a lower consumption of red meat for health benefits. National governments are, however, rather inactive on this topic, leaving the initiative to the civil society.

    Environmentally benign modern bioenergy is widely acknowledged as a potential substitute for fossil fuels to offset the human dependence on fossil fuels for energy. We have profiled Cameroon, a country where modern bioenergy remains largely untapped due to a lack of availability of biomass data...... liters of ethanol annually to displace 18–48% of the national consumption of gasoline. Alternatively, the residues could provide 0.08–0.22 billion liters of biomass to Fischer Tropsch diesel annually to offset 17–45% of diesel fuel use. For the generation of bioelectricity, the residues could supply 0.......76–2.02 TW h, which is the equivalent of 15–38% of Cameroon’s current electricity consumption. This could help spread electricity throughout the country, especially in farming communities where the residues are plentiful. The residues could, however, offset only 3% of the national consumption of traditional...

  16. Ways of signal transmission and physiological role of electrical potentials in plants

    Directory of Open Access Journals (Sweden)

    Halina Dziubińska

    2011-01-01

    Full Text Available Plants are subject to stimuli from the environment on which they strongly depend and in contrast to animals, they are unable to escape harmful influences. Therefore, being able to receive stimuli they have developed adequate responses to them. Such a reaction can occur in the area of a stimulus action or cover the whole plant or its parts. In the latter case, it is a systemic reaction. The plant reaction is expressed by various intensity, rate and kind of response. It is interesting to know the character of the signal informing about a stimulus, the routes of its propagation and the transmission mechanism. Three conceptions of excitation are distinguished: 1 propagation of chemical agents formed at the site of a stimulus action with the flow of the phloem sap or through the atmosphere (in the case of volatile substances to other plant parts, 2 a very fast transmission by the xylem in the wave of hydraulic pressure formed after a plant damage. From combining the "hydraulic" and "chemical" hypothesis a conception of hydraulic dispersion has been formulated which assumes that chemical substances synthetized after an injury can be transferred very fast with the wave of hydraulic pressure changes in the whole plant, 3 a stimulus evokes the action potential (AP, and its transmission along the whole plant, plant organ or specialized tissue, by local circuits from cell to cell. Strong, damaging stimuli can evoke variation potentials (VPs, the character of which differs from APs. It is postulated that transmission of VP occurs by a hydraulic dispersion and electrical changes seem to be secondary phenomena.

    Fewer than 50% of women who meet the medical/behavioral criteria for infertility receive medical services. Estimating the number of women who both meet the medical/behavioral criteria for infertility and who have pro-conception attitudes will allow for better estimates of the potential need and unmet need for infertility services in the United States. The National Survey of Fertility Barriers was administered by telephone to a probability sample of 4,712 women in the United States. The sample for this analysis was 292 women who reported an experience of infertility within 3 years of the time of the interview. Infertile women were asked if they were trying to conceive at the time of their infertility experience and if they wanted to have a child to determine who could be considered in need of services. Among U.S. women who have met medical criteria for infertility within the past three years, 15.9% report that they were neither trying to have a child nor wanted to have a child and can be classified as not in need of treatment. Of the 84.9% of infertile women in need of treatment, 58.1% did not even talk to a doctor about ways to become pregnant. Even after taking into account that not all infertile women are in need of treatment, there is still a large unmet need for infertility treatment in the United States. Studies of the incidence of infertility should include measures of both trying to have a child and wanting to have a child.

    2010-12-01

    Full Text Available This article aims at resuming and critically scrutinizing the debate on the politics of difference taken among liberal feminist political theorists. Firstly, I shall provide an overview of theoretical attempts to legitimate the politicization of collective-based subjects taking into account the problem of essentialism. Then I will argue that an exclusive focus on the relationship between essentialism and the conceptualization of collective-based subjects tends to overshadow the relationship between the politicization of differences and a new way of doing politics. I will defend the view that the politicization of differences is transforming rather than undermining the functioning of the polity and the possibility of real social justice. I shall evaluate the works of Anne Phillips and Iris Marion Young as offering new ways of reshaping the political sphere in order to enable proper institutional action against structural inequalities.

    Microorganisms have a long track record as important sources of novel bioactive natural products, particularly in the field of drug discovery. While microbes have been shown to biosynthesize a wide array of molecules, recent advances in genome sequencing have revealed that such organisms have the potential to yield even more structurally diverse secondary metabolites. Thus, many microbial gene clusters may be silent under standard laboratory growth conditions. In the last ten years, several methods have been developed to aid in the activation of these cryptic biosynthetic pathways. In addition to the techniques that demand prior knowledge of the genome sequences of the studied microorganisms, several genome sequence-independent tools have been developed. One of these approaches is microorganism co-culture, involving the cultivation of two or more microorganisms in the same confined environment. Microorganism co-culture is inspired by the natural microbe communities that are omnipresent in nature. Within these communities, microbes interact through signaling or defense molecules. Such compounds, produced dynamically, are of potential interest as new leads for drug discovery. Microorganism co-culture can be achieved in either solid or liquid media and has recently been used increasingly extensively to study natural interactions and discover new bioactive metabolites. Because of the complexity of microbial extracts, advanced analytical methods (e.g., mass spectrometry methods and metabolomics) are key for the successful detection and identification of co-culture-induced metabolites. This review focuses on co-culture studies that aim to increase the diversity of metabolites obtained from microbes. The various strategies are summarized with a special emphasis on the multiple methods of performing co-culture experiments. The analytical approaches for studying these interaction phenomena are discussed, and the chemical diversity and biological activity observed among the

    To test whether aerobic exercise can help build self-control stamina in healthy female young adults. Stamina in this context is defined as the capability to endure ego depletion, which can be measured with a self-control task following another activity also requiring self-control. Forty-five healthy undergraduate women were randomized to either an experimental group or control group. Participants in the experimental group were required to run in their campus running field for 30 min for a period of 5 weeks. Individuals in the control group were required to do diary entries regarding self-control in their daily lives, also for a period of 5 weeks. Before and after the 5-week intervention, participants completed a pain threshold test, a color word Stroop task and the following Cold Pressor Task (CPT) (with and without a distraction component). There was significant decrease of pain tolerance in session 2 relative to session 1 in the control group, but no such decline was found in the experimental group (though the improvement of pain tolerance was not significant), possibly suggesting successful self-control against this kind of decline. Five weeks of aerobic exercise increased self-control after ego depletion in terms of pain tolerance. These findings suggest that aerobic exercise may serve as a potential effective intervention for enhancing self-control in a college female population.

    Identifying needs in patients who utilize the emergency department (ED) soon after being discharged from inpatient care is essential for planning appropriate care-transition interventions. To examine differences in stakeholder perspectives on reasons for ED care soon after hospital discharge and interventions that could be useful to prevent these ED visits. A convenience sample of 135 patients who presented to an urban teaching hospital ED hospital discharge, their caregivers (when present), and emergency physicians were administered identical structured surveys. Concordance and agreement rates between patient-physician and patient-caregiver dyads were calculated. Concordances between stakeholders were poor, with weighted kappas ranging from 0.02 to 0.34 for patient-physician dyads and 0.03 to 0.68 for patient-caregiver dyads. Emergency physicians and caregivers identified factors between 1% and 42% of the time the patients did not. Less than half of any stakeholder could identify an intervention to potentially prevent the ED visit. Our findings suggest the difficulty in forming unified definitions for root cause of ED visits soon after hospital discharge and support the use of multiple stakeholders in identifying appropriate targets for care-transition interventions. © 2014 Society of Hospital Medicine.

  7. The Milky Way Skeleton

    2015-01-01

    Recently, Goodman et al. (2014) argued that a very long, very thin infrared dark cloud 'Nessie' lies directly in the Galactic mid-plane and runs along the Scutum-Centaurus arm in position-position-velocity space as traced by low density CO and high density NH3 gas. Nessie was presented as the first 'bone' of the Milky Way, an extraordinarily long, thin, high contrast filament that can be used to map our galaxy's 'skeleton.' We present the first evidence of additional 'bones' in the Milky Way Galaxy, arguing that Nessie is not a curiosity but one of many filaments that could potentially trace galactic structure. Our ten bone candidates are all long, filamentary, mid-infrared extinction features which lie parallel to, and no more than twenty parsecs from, the physical Galactic mid-plane. We use CO, N2H+, and NH3 radial velocity data to establish the location of the candidates in position-velocity space. Of the ten filaments, three candidates have a projected aspect ratio of >50:1 and run along, or extremely close to, the Scutum-Centaurus arm in position-velocity space. Evidence suggests that these three candidates are Nessie-like features which mark the location of the spiral arms in both physical space and position-velocity space. Other candidates could be spurs, feathers, or interarm clouds associated with the Milky Way's galactic structure. As molecular spectral-line and extinction maps cover more of the sky at increasing resolution and sensitivity, we hope to find more bones in future studies, to ultimately create a global-fit to the Galaxy's spiral arms by piecing together individual skeletal features.

    Full Text Available The gold standards for measurement of sleep and wake are polysomnography (PSG and the multiple sleep latency test (MSLT and will remain so. Actigraphy is cheap, less labor intensive for the sleep laboratory and gives no burden for the patient. Major features of sleep (time in bed, total sleep time, sleep onset latency, wake after sleep onset and naps during the day are easily quantified. If done over at least five days the results are in a reasonable way comparable to those of PSG. Obviously, actigraphy provides less details of sleep and the way it is disturbed. From the combination of PSG and one week actigraphy, one gets all details of sleep and wake and their fluctuations over time. As stand alone technique, actigraphy is indicated in young children, mentally handicapped patients and in the assessment of therapy for sleep disorders. In our opinion assessment of sleep disorders in children should include actigraphy over at least 5-7 24 hour days, if possible combined with one or two nights PSG. As there are no strict rules and normal values for MSLT in children, actigraphy is also helpful as tool for global assessment of hypersomnia in young patients.

    2016-03-01

    Full Text Available The paper discusses analogies between the way in which infinity is understood and dealt with in mathematics and in Jewish tradition. It begins with recalling the classical debate about infinity in the field of the foundations of mathematics. Reading an important paper by A. Robinson, we come to the conclusion that mathematicians work “as if” infinite totalities existed. They do so by following the rules of their formalized discourse which, at least if it refers to anything at all, also refers to such totalities. The paper describes how, according to Jewish tradition, infinity is also not theological: instead of thinking that they own some infinite being or relate to it, observant Jews follow Jewish law.

    Full Text Available Researchers know very little about extit{how} people choose mates. To remedy this, the present study examined the influence of number of potential mates and mate-standard strength on single women's choice satisfaction and strategy use. Single women chose one potential partner from a set of 4, 24, or 64 options presented on a real dating website. Participants adjusted to an increasing number of options by changing their decision-making strategies, such that they relied on noncompensatory, attribute-based strategies as the number of options increased. Across conditions they reported similar levels of satisfaction with the choice process and the person selected. Mate-standard strength qualified some of the results, however, as women with higher mate standards preferred extensive choice, and they tended to prefer compensatory choice strategies and were more satisfied with the option selected when he was selected from among many.

    Full Text Available The Mediterranean area have a special concept of competitiveness topic. Normally is that region not so industrial and knowledge based oriented as a North Europe.That countries can't reach the same development level as the north one. Lisbon's and Goethenburg's strategies create the main framework of development programme. Mediterranean programme is such a case. European internal market has forced the EU countries to increase competitiveness. The economic prosperity of countries is associated with their ability to generate or attract economic activities which are able to increase income by performing well on themarket. Financial crisis in the EU has changed the look on the competitiveness research. Economy in the main countries has to find way of recovery. Former giants of the financial world have found themselves suddenly facing bankruptcy.Inevitably, the crisis is also having an effect on households and businesses - economic growth has slowed sharply and in some EU countries unemployment has begun to increase for the first time in several years. Form that perspective we have to find the right solution of European competitiveness.

  3. The Fourth Way in Finland

    Directory of Open Access Journals (Sweden)

    Vesa Iitti

    2008-01-01

    Full Text Available This article focuses on the general history of the Fourth Way in Finland. The Fourth Way, or simply ‘the Work’, began as a Greco-Armenian man named Georges Ivanovich Gurdjieff (1866?–1949 gathered groups of pupils in St Petersburg and Moscow in 1912. To these groups, Gurdjieff started to teach what he had learned and synthesized between ca 1896 and 1912 during his travels on spiritual search of Egypt, Crete, Sumeria, Assyria, the Holy Land, Mecca, Ethiopia, Sudan, India, Afghanistan, the northern valleys of Siberia, and Tibet. Neither Gurdjieff nor any of his disciples called themselves a church, a sect, or anything alike, but referred to themselves simply as ‘the Work’, or as ‘the Fourth Way’. The name ‘the Fourth Way’ originates in a Gurdjieffian view that there are essentially three traditional ways of spiritual work: those of a monk, a fakir, and a yogi. These ways do not literally refer to the activities of a monk, a fakir, and a yogi, but to similar types of spiritual work emphasizing exercise of emotion, body, or mind. Gurdjieff’s teaching is a blend of various influences that include Suf­ism, orthodox Christianity, Buddhism, Kabbalah, and general elem­ents of various occult teachings of both the East and the West. Gurdjieff’s teaching is a blend of various influences that include Suf­ism, orthodox Christianity, Buddhism, Kabbalah, and general elem­ents of various occult teachings of both the East and the West. It is a unique combination of cosmology, psychology, theory of evolution, and overall theory and practise aiming to help individ­uals in their efforts towards what is called ‘self-remembering’.

    Pascale, R; Millemann, M; Gioja, L

    1997-01-01

    More and more companies struggle with growing competition by introducing improvements into every aspect of performance. But the treadmill keeps moving faster, the companies keep working harder, and results improve slowly or not at all. The problem here is not the improvement programs. The problem is that the whole burden of change typically rests on so few people. Companies achieve real agility only when every function and process--when every person--is able and eager to rise to every challenge. This type and degree of fundamental change, commonly called revitalization or transformation, is what many companies seek but rarely achieve because they have never before identified the factors that produce sustained transformational change. The authors identify three interventions that will restore companies to vital agility and then keep them in good health: incorporating employees fully into the principal business challenges facing the company, leading the organization in a different way in order to sharpen and maintain incorporation and constructive stress, and instilling mental disciplines that will make people behave differently and then help them sustain their new behavior. The authors discovered these basic sources of revitalization by tracking the change efforts of Sears, Roebuck & Company, Royal Dutch Shell, and the United States Army. The organizations used these interventions to alter the way their people experienced their own power and identity, as well as the way they dealt with conflict and learning. As at Sears, Shell, and the U.S. Army, any major shift in those four elements will create a landmark shift in any organization's operating state or culture.

    1998-11-01

    Dr. Willem J. Kolff's imaginative venturesomeness in adopting "new ways of thinking" has served as an encouraging model for this author's research career. In appreciation of his leadership and beginning with the favorable results that attended the initial use of the Brigham-Kolff artificial kidney at a renal center in the Korean war, this presentation summarizes four experiences to illustrate how "new ways of thinking" produced new results and new research, namely, the concept and use of prophylactic daily hemodialysis; the use of a model of acute renal failure in rats to examine mechanisms of pathogenesis and means of prevention; the recognition of patients' uremic illness as an encephalopathy that can be quantified by appropriate measures; and the use of daily peritoneal dialysis and quantified EEGs in rats to explore relationships between dialysis-induced concentrations of potentially toxic solutes, quantified indices of symptomatic uremic encephalopathy, and concurrent, localized metabolic abnormalities in the brain. The results of these "new ways of thinking" suggest that we may ultimately come to understand the clinical uremic illness and its response to dialysis.

    Moore, Laurie Jo; Goldner-Vukov, Mila

    2009-12-01

    This paper explores the essential features of recovery and the need for an existential approach in psychiatry. The biopsychosocial model often fails to sufficiently validate the existential suffering of patients. We review the major principles of recovery and the philosophical and psychiatric principles of existentialism. The ontological or intrinsic existential issues of death, isolation, freedom and meaninglessness are described and their manifestations are explored in clinical syndromes. When ultimate existential concerns are recognised, patients have an opportunity to understand their life on a deeper level that is not defined as a medical disorder but as a part of human existence. Understanding that existential concerns underlie a great deal of human behaviour helps to free patients from the stigma of psychiatric labels. An existential approach is a humanistic way toward recovery.

  11. Half way round the LHC

    CERN Multimedia

    CERN Bulletin

    The LHC operations teams are preparing the machine for circulating beams and things are going very smoothly. ALICE and LHCb are getting used to observing particle tracks coming from the LHC beams. During the weekend of 7-8 November, CMS also  saw its first signals from beams dumped just upstream of  the experiment cavern.   Operators in the CMS control room observe the good performance of their detector. Particles are smoothly making their way around the 27 km circumference of the LHC. Last weekend (7-8 November), the first bunches of injection energy protons completed their journey (anti-clockwise) through three octants of the LHC’s circumference and were dumped in a collimator just before entering the CMS cavern. The particles produced by the impact of the protons on the tertiary collimators (used to stop the beam) left their tracks in the calorimeters and the muon chambers of the experiment. The more delicate inner detectors were switched off for protection reasons....

  13. Two-Way communication with energy exchange

    DEFF Research Database (Denmark)

    Popovski, Petar; Simeone, Osvaldo

    2012-01-01

    The conventional assumption made in the design of communication systems is that the energy used to transfer information between a sender and a recipient cannot be reused for future communication tasks. A notable exception to this norm is given by passive RFID systems, in which a reader can transfer...... both information and energy via the transmitted radio signal. Conceivably, any system that exchanges information via the transfer of given physical resources (radio waves, particles, qubits) can potentially reuse, at least part, of the received resources for communication later on. In this paper, a two......-way communication system is considered that operates with a given initial number of physical resources, referred to as energy units. The energy units are not replenished from outside the system, and are assumed, for simplicity, to be constant over time. A node can either send an “on” symbol (or “1”), which costs...

The named is the mother of ten thousand things. Ever desireless, one can see the mystery. Ever desiring, one can see the manifestations. These two spring from the same source but differ in name; this appears as darkness. Darkness within darkness.

    The opinions and a biographical sketch of Wes Jackson, the founder of the Land Institute, are presented. The land Institute near Salina, Kansas is a nonprofit organization devoted to sustainable agriculture. Opinions are provided on the relationship of the Land Institute to sustainable agriculture, the definition of sustainability, the feasibility of replication of his work, his ideas about the destruction wreaked by the plow vs. the sword, technology and population growth, the future farmer, and the speed with which modern science has destroyed the ozone layer. Sustainable agriculture is using the prairie to provide answers to how agriculture can work with nature; the approach will take longer but will sustain both agriculture and people for another 10,000 years. The system runs on sunlight and recycles all materials and is based on the principles of ecosystems, which have been around for hundreds of years. Agricultural technology is based on a fossil fuel intensive infrastructure and is "parachuted into Third World countries." "Corn - the gift of the gods has been the killer of this continent." 50% of the topsoil has been lost, and soil is more important than oil. Advances in biotechnology are seen as the "human cleverness" approach; the preference is for an ecological approach first. Biotechnology tells how to "spin wheels faster," but it also generates more waste. The future farmer is more like the 19th century British naturalist. A projection is that 1st the oil is used up, then the natural gas, and when nuclear power is embraced, Murphy's Law must be repealed. It is important to understand the "we can'ts". Realization of limits will direct energy to the sun's potential and recycling and the flow of energy. Descartes' notion of correctable ignorance must be repudiated. Our knowledge-based world has led to acid rain, global warming, the ozone hole, and Chernobyl. It took just 25 years for chlorofluorocarbons to destroy the ozone layer. A philosophical shift in

    mean that more patients are willing to start insulin therapy earlier than with conventional SC insulin therapy? With TI we have a product that has improved pharmacological properties (also in comparison to Exubera) for coverage of prandial insulin requirements. Subsequently, in the clinical trials performed, postprandial glycaemic excursions were lower than with SC injection of RHI or rapid-acting insulin analogues. This only in part (if at all) results in an improved metabolic control in general (= lower HbA1c) (see below). The outlook for 2011 is that there are chances that we shall have an inhaled insulin product on the market. Probably also the first OI will be submitted to the regulatory authorities for market approval or will even be available in less regulated markets. In order to select all relevant publications about new ways of insulin delivery I performed a PUBMED search and also checked the table of contents of a number of journals that publish heavily in this area of research as well references in the publications I found for additional references. Selection of the manuscripts from all publications was predominately based on the fact whether they presented data from clinical studies or not. The selected studies were critically reviewed for novelty and appropriate study design etc. In some cases also reviews about a given topic were selected if they provide relevant novel insights. © 2011 Blackwell Publishing Ltd.

  17. Characterizing Milky Way Tidal Streams and Dark Matter with MilkyWay@home

    Science.gov (United States)

    Newberg, Heidi Jo; Shelton, Siddhartha; Weiss, Jake

    2018-01-01

    MilkyWay@home is a 0.5 PetaFLOPS volunteer computing platform that is mapping out the density substructure of the Sagittarius Dwarf Tidal Stream, the so-called bifurcated portion of the Sagittarius Stream, and the Virgo Overdensity, using turnoff stars from the Sloan Digital Sky Survey. It is also using the density of stars along tidal streams such as the Orphan Stream to constrain properties of the dwarf galaxy progenitor of this stream, including the dark matter portion. Both of these programs are enabled by a specially-built optimization package that uses differential evolution or particle swarm methods to find the optimal model parameters to fit a set of data. To fit the density of tidal streams, 20 parameters are simultaneously fit to each 2.5-degree-wide stripe of SDSS data. Five parameters describing the stellar and dark matter profile of the Orphan Stream progenitor and the time that the dwarf galaxy has been evolved through the Galactic potential are used in an n-body simulation that is then fit to observations of the Orphan Stream. New results from MilkyWay@home will be presented. This project was supported by NSF grant AST 16-15688, the NASA/NY Space Grant fellowship, and contributions made by The Marvin Clan, Babette Josephs, Manit Limlamai, and the 2015 Crowd Funding Campaign to Support Milky Way Research.

    Newberg, Heidi Jo; Newby, Matthew; Desell, Travis; Magdon-Ismail, Malik; Szymanski, Boleslaw; Varela, Carlos

    2014-01-01

    MilkyWay@home is a volunteer computing project that allows people from every country in the world to volunteer their otherwise idle processors to Milky Way research. Currently, more than 25,000 people (150,000 since November 9, 2007) contribute about half a PetaFLOPS of computing power to our project. We currently run two types of applications: one application fits the spatial density profile of tidal streams using statistical photometric parallax, and the other application finds the N-body simulation parameters that produce tidal streams that best match the measured density profile of known tidal streams. The stream fitting application is well developed and is producing published results. The Sagittarius dwarf leading tidal tail has been fit, and the algorithm is currently running on the trailing tidal tail and bifurcated pieces. We will soon have a self-consistent model for the density of the smooth component of the stellar halo and the largest tidal streams. The N-body application has been implemented for fitting dwarf galaxy progenitor properties only, and is in the testing stages. We use an Earth-Mover Distance method to measure goodness-of-fit for density of stars along the tidal stream. We will add additional spatial dimensions as well as kinematic measures in a piecemeal fashion, with the eventual goal of fitting the orbit and parameters of the Milky Way potential (and thus the density distribution of dark matter) using multiple tidal streams.

  1. The Skeleton of the Milky Way

    Science.gov (United States)

    Zucker, Catherine; Battersby, Cara; Goodman, Alyssa

    2015-12-01

    Recently, Goodman et al. argued that the very long, very thin infrared dark cloud “Nessie” lies directly in the Galactic midplane and runs along the Scutum-Centaurus Arm in position-position-velocity (p-p-v) space as traced by lower-density {{CO}} and higher-density {{NH}}3 gas. Nessie was presented as the first “bone” of the Milky Way, an extraordinarily long, thin, high-contrast filament that can be used to map our Galaxy’s “skeleton.” Here we present evidence for additional bones in the Milky Way, arguing that Nessie is not a curiosity but one of several filaments that could potentially trace Galactic structure. Our 10 bone candidates are all long, filamentary, mid-infrared extinction features that lie parallel to, and no more than 20 pc from, the physical Galactic mid-plane. We use {{CO}}, {{{N}}}2{{{H}}}+, {{{HCO}}}+, and {{NH}}3 radial velocity data to establish the three-dimensional location of the candidates in p-p-v space. Of the 10 candidates, 6 also have a projected aspect ratio of ≥50:1 run along, or extremely close to, the Scutum-Centaurus Arm in p-p-v space; and exhibit no abrupt shifts in velocity. The evidence presented here suggests that these candidates mark the locations of significant spiral features, with the bone called filament 5 (“BC_18.88-0.09”) being a close analog to Nessie in the northern sky. As molecular spectral-line and extinction maps cover more of the sky at increasing resolution and sensitivity, it should be possible to find more bones in future studies.

    Studying the large-scale structure of the Milky Way is difficult given that were stuck in its interior which means we cant step back for a broad overview of our home. Instead, a recent study uses distant variable stars to map out a picture of whats happening in the outskirts of our galaxy.Mapping with TracersPhase-folded light curve for two of the RR Lyrae stars in the authors sample, each with hundreds of observations over 7 years. [Cohen et al. 2017]Since observing the Milky Way from the outside isnt an option, we have to take creative approaches to mapping its outer regions and measuring its total mass and dark matter content. One tool used by astronomers is tracers: easily identifiable stars that can be treated as massless markers moving only as a result of the galactic potential. Mapping the locations and motions of tracers allows us to measure the larger properties of the galaxy.RR Lyrae stars are low-mass, variable stars that make especially good tracers. They pulsate predictably on timescales of less than a day, creating distinctive light curves that can easily be distinguished and tracked in wide-field optical imaging surveys over long periods of time. Their brightness makes them detectable out to large distances, and their blue color helps to separate them from contaminating stars in the foreground.Best of all, RR Lyrae stars are very nearly standard candles: their distances can be determined precisely with only knowledge of their measured light curves.Locations on the sky of the several hundred outer-halo RR Lyrae stars in the authors original sample. The red curve shows the location of the Sagittarius stream, an ordered structure the authors avoided so as to only have unassociated stars in their sample.

    2015-04-01

    Full Text Available Quantum cryptographic protocols solve the longstanding problem of distributing a shared secret string to two distant users by typically making use of one-way quantum channel. However, alternative protocols exploiting two-way quantum channel have been proposed for the same goal and with potential advantages. Here, we overview a security proof for two-way quantum key distribution protocols, against the most general eavesdropping attack, that utilize an entropic uncertainty relation. Then, by resorting to the “smooth” version of involved entropies, we extend such a proof to the case of finite key size. The results will be compared to those available for one-way protocols showing some advantages.

    Carlton, S.; Andriola, T.

    1992-12-01

    The use of existing rights-of-way (ROW) is assessed for maglev systems by estimating trip times and land acquisition requirements for potential maglev corridors while meeting passenger comfort limits. Right-of-way excursions improve trip time but incur a cost for purchasing land. The final report documents findings of the eight tasks in establishing right-of-way feasibility by examining three city-pair corridors in detail and developing an approximation method for estimating route length and travel times in 20 additional city-pair corridor portions and 21 new corridors. The use of routes independent of existing railroad or highway right-of-way have trip time advantages and significantly reduce the need for aggressive guideway geometries on intercity corridors. Selection of the appropriate alignment is determined by many corridor specific issues. Use of existing intercity rights-of-way may be appropriate for parts of routes on a corridor-specific basis and for urban penetration where vehicle speeds are likely to be reduced by policy due to noise and safety considerations, and where land acquisition costs are high. Detailed aspects of available rights-of-way, land acquisition costs, geotechnical issues, land use, and population centers must be examined in more detail on a specific corridor basis before the proper or best maglev alignment can be chosen.

    2013-08-01

    The observed population of the Milky Way satellite galaxies offers a unique testing ground for galaxy formation theory on small scales. Our novel approach was to investigate the clustering of the known Milky Way satellite galaxies and to quantify the amount of substructure within their distribution using a two-point correlation function statistic in each of three spaces: configuration space, line-of-sight velocity space, and four-dimensional (4D) phase space. These results were compared to those for three sets of subhalos in the Via Lactea II cold dark matter (CDM) simulation defined to represent the luminous dwarfs. We found no evidence at a significance level above 2{sigma} of substructure within the distribution of the Milky Way satellite galaxies in any of the three spaces. The 'luminous' subhalo sets are more strongly clustered than are the Milky Way satellites in all three spaces and over a broader range of scales in 4D phase space. Each of the 'luminous' subhalo sets are clustered as a result of substructure within their line-of-sight velocity space distributions at greater than 3{sigma} significance, whereas the Milky Way satellite galaxies are randomly distributed in line-of-sight velocity space. While our comparison is with only one CDM simulation, the inconsistencies between the Milky Way satellite galaxies and the Via Lactea II subhalo sets for all clustering methods suggest a potential new 'small-scale' tension between CDM theory and the observed Milky Way satellites. Future work will obtain a more robust comparison between the observed Milky Way satellites and CDM theory by studying additional simulations.

  7. The Milky Way and other spiral galaxies

    Directory of Open Access Journals (Sweden)

    Wang J.L.

    2012-02-01

    Full Text Available Cosmologists have often considered the Milky Way as a typical spiral galaxy, and its properties have considerably influenced the current scheme of galaxy formation. Here we compare the general properties of the Milky Way disk and halo with those of galaxies selected from the SDSS. Assuming the recent measurements of its circular velocity results in the Milky Way being offset by ~2σ from the fundamental scaling relations. On the basis of their location in the (MK, Rd, Vflat volume, the fraction of SDSS spirals like the MilkyWay is only 1.2% in sharp contrast with M31, which appears to be quite typical. Comparison of the Milky Way with M31 and with other spirals is also discussed to investigate whether or not there is a fundamental discrepancy between their mass assembly histories. Possibly the Milky Way is one of the very few local galaxies that could be a direct descendant of very distant, z = 2-3 galaxies, thanks to its quiescent history since thick disk formation.

    The Milky Way is typically thought of as a spiral galaxy, but our understanding of its detailed structure remains vague thanks to our observational vantage point within its disk. Most of what we do know about the Milky Way's three-dimensional geometry comes from velocity-resolved observations of gas and stars. But, recently, it has become possible to combine exquisitely sensitive observations of dust with more traditional kinematically-resolved observations of gas to reveal totally new structures within the Milky Way. In this talk, I will explain why we now believe that some extraordinarily long so-called "infrared dark clouds" are in fact the "bones" of the Galaxy, marking out the true mid-plane of its disk to within less than a few parsecs. We call the long features "bones" thanks to recent numerical simulations of spiral galaxies that show a network of over-dense filaments within and between the arms that resemble an endoskeleton for a galaxy. The talk will highlight how both large surveys and new visualization tools have been critical in this investigation. By way of example, I will argue that the "Nessie" Infrared Dark Cloud is a nearly-continuous, many-hundreds-of-pc-long, ~pc-thick, structure, lying within a few pc of the mid-plane of the MIlky Way.

    WFIRST will yield a transformative impact in measuring and characterizing resolved stellar populations in the Milky Way. The proximity and level of detail that such populations need to be studied at directly map to all three pillars of WFIRST capabilities - sensitivity from a 2.4 meter space based telescope, resolution from 0.1" pixels, and large 0.3 degree field of view from multiple detectors. In this poster, we describe the activities of the WFIRST Science Investigation Team (SIT), "Resolving the Milky Way with WFIRST". Notional programs guiding our analysis include targeting sightlines to establish the first well-resolved large scale maps of the Galactic bulge aand central region, pockets of star formation in the disk, benchmark star clusters, and halo substructure and ultra faint dwarf satellites. As an output of this study, our team is building optimized strategies and tools to maximize stellar population science with WFIRST. This will include: new grids of IR-optimized stellar evolution and synthetic spectroscopic models; pipelines and algorithms for optimal data reduction at the WFIRST sensitivity and pixel scale; wide field simulations of Milky Way environments including new astrometric studies; and strategies and automated algorithms to find substructure and dwarf galaxies in the Milky Way through the WFIRST High Latitude Survey.

  13. Microfluidic Neurons, a New Way in Neuromorphic Engineering?

    Directory of Open Access Journals (Sweden)

    Timothée Levi

    2016-08-01

    Full Text Available This article describes a new way to explore neuromorphic engineering, the biomimetic artificial neuron using microfluidic techniques. This new device could replace silicon neurons and solve the issues of biocompatibility and power consumption. The biological neuron transmits electrical signals based on ion flow through their plasma membrane. Action potentials are propagated along axons and represent the fundamental electrical signals by which information are transmitted from one place to another in the nervous system. Based on this physiological behavior, we propose a microfluidic structure composed of chambers representing the intra and extracellular environments, connected by channels actuated by Quake valves. These channels are equipped with selective ion permeable membranes to mimic the exchange of chemical species found in the biological neuron. A thick polydimethylsiloxane (PDMS membrane is used to create the Quake valve membrane. Integrated electrodes are used to measure the potential difference between the intracellular and extracellular environments: the membrane potential.

    With more than 100 million Americans on the Internet, the physician-patient relationship is evolving. The Net brings with it unlimited potential for communication and information dissemination, but these benefits do come with some side effects. No everything on the Net is reliable or credible, but many patients don't understand that. For this reason and others, physicians must involve themselves with online communication and e-commerce. There are many realistic and practical ways for physicians to do this, and not all of them involve building a Web site. Sending patients clinical information in a cost-effective manner, improving receivables management, and decreasing the volume of phone calls are just some of the many ways the Net can enhance your practice. Think of the Net as just another business tool--not a replacement for physician-patient relationships. Like the telephone before it, the Net affords improved communication, patient education, and relationship-building with patients.

    Full Text Available Delineate the Spanish teaching trajectory in the Brazilian educational system is, if not hard, a surprising task. In this job we will reflect about the Spanish language trajectory in Brazil. To try to understand the way how the Brazilian educative system  understands the Spanish teaching in our territory, will be analyzed the movements to offer this language at the Brazilian basic education and some of the main actions carried out until the moment. To map the way, we will focus in four moments between 1942 until the present.  Our reflection shows that, in spite of the incentive realized in the elaboration of a Spanish insertion in the Brazilian educational system proposal, we didn’t build a solid linguistic policy which attends to the teaching specificities in our country.

    2013-03-01

    Full Text Available The notion of bios is a key-concept in Foucault's research. In the studies about the ancient world, bios stands out as an ethic substance relevant to the practice, the control and the transformation of the self. It is worth investigating the analogies and the differences between the notion of bios as it is meant in the last lectures at the Collège de France and that of bios as a creative force, shared and plural, that we find in previous seasons of Foucault research. The issue of 'way of life' allows us to explore the ambivalences of this topic. In its singular/plural declination, bios raises questions about the common living, which results from the coexistence and sharing of different ways of life – bioi – that cut through the ground of the institutionalized relationships.

    Full Text Available Cohen and Machalek’s (1988 evolutionary ecological theory of crime explains why obscure forms of predation can be the most lucrative. Sutherland explained that it is better to rob a bank at the point of a pen than of a gun. The US Savings and Loans scandal of the 1980s suggested ‘the best way to rob a bank is to own one’. Lure constituted by the anomie of warfare and transition to capitalism in former Yugoslavia revealed that the best way to rob a bank is to control the regulatory system: that is, to control a central bank. This makes possible theft of all the people’s money in a society. The criminological imagination must attune to anomie created by capitalism, and to the evolutionary ecology of lure.

  3. Comparative analysis of the performance of One-Way and Two-Way urban road networks

    Science.gov (United States)

    Gheorghe, Carmen

    2017-10-01

    The fact that the number of vehicles is increasing year after year represents a challenge in road traffic management because it is necessary to adjust the road traffic, in order to prevent any incidents, using mostly the same road infrastructure. At this moment one-way road network provides efficient traffic flow for vehicles but it is not ideal for pedestrians. Therefore, a proper solution must be found and applied when and where it is necessary. Replacing one-way road network with two-way road network may be a viable solution especially if in the area is high pedestrian traffic. The paper aims to highlight the influence of both, one-way and two-way urban road networks through an experimental research which was performed by using traffic data collected in the field. Each of the two scenarios analyzed were based on the same traffic data, the same geometrical conditions of the road (lane width, total road segment width, road slopes, total length of the road network) and also the same signaling conditions (signalised intersection or roundabout). The analysis which involves two-way scenario reveals changes in the performance parameters like delay average, stops average, delay stop average and vehicle speed average. Based on the values obtained, it was possible to perform a comparative analysis between the real, one-way, scenario and the theoretical, two-way, scenario.

    2013-01-01

    Long before GPS, Google Earth, and global transit, humans traveled vast distances using only environmental clues and simple instruments. John Huth asks what is lost when modern technology substitutes for our innate capacity to find our way. Encyclopedic in breadth, weaving together astronomy, meteorology, oceanography, and ethnography, The Lost Art of Finding Our Way puts us in the shoes, ships, and sleds of early navigators for whom paying close attention to the environment around them was, quite literally, a matter of life and death. Haunted by the fate of two young kayakers lost in a fogbank off Nantucket, Huth shows us how to navigate using natural phenomena—the way the Vikings used the sunstone to detect polarization of sunlight, and Arab traders learned to sail into the wind, and Pacific Islanders used underwater lightning and “read” waves to guide their explorations. Huth reminds us that we are all navigators capable of learning techniques ranging from the simplest to the most sophisticated skil...

  7. Outer Regions of the Milky Way

    Science.gov (United States)

    Figueras, Francesca

    With the start of the Gaia era, the time has come to address the major challenge of deriving the star formation history and evolution of the disk of our Milky Way. Here we review our present knowledge of the outer regions of the Milky Way disk population. Its stellar content, its structure and its dynamical and chemical evolution are summarized, focussing on our lack of understanding both from an observational and a theoretical viewpoint. We describe the unprecedented data that Gaia and the upcoming ground-based spectroscopic surveys will provide in the next decade. More in detail, we quantify the expected accuracy in position, velocity and astrophysical parameters of some of the key tracers of the stellar populations in the outer Galactic disk. Some insights on the future capability of these surveys to answer crucial and fundamental issues are discussed, such as the mechanisms driving the spiral arms and the warp formation. Our Galaxy, the Milky Way, is our cosmological laboratory for understanding the process of formation and evolution of disk galaxies. What we learn in the next decades will be naturally transferred to the extragalactic domain.

    A global method characterizing the invariant connections on an abelian principal bundle under a group of transformations is applied in order to get gauge invariant electromagnetic (elm.) potentials in a systematic way. So, we have classified all the elm. gauge invariant potentials under the Poincare subgroups of dimensions 4, 5, and 6, up to conjugation. It is paid attention in particular to the situation where these subgroups do not act transitively on the space-time manifold. We have used the same procedure for some galilean subgroups to get nonrelativistic potentials and study the way they are related to their relativistic partners by means of contractions. Some conformal gauge invariant potentials have also been derived and considered when they are seen as consequence of an enlargement of the Poincare symmetries. (orig.)

  9. To Stretch and Search for Better Ways

    Moore, John W.

    2000-06-01

    There's a lot to do to get each issue of this Journal ready for publication, and there's a lot that can go awry during that process. We the editorial staff do our utmost to make certain that each issue is the best it can possibly be, but, of necessity, a lot of our effort is focused on solving problems, correcting errors, and avoiding pitfalls. It is not surprising that we sometimes lose sight of the bigger picture--all of the things that came out as well as or better than we hoped they would. Therefore it gives us great pleasure when a reader applauds (and thereby rewards) our efforts. One such communication inspired this editorial. I have appreciated the extra effort put forward by the staff to make the Journal really come alive. The high quality of the Journal serves as an incentive to chemical educators to stretch and search for better ways to inspire our students. I fervently hope that we do encourage you "to stretch and search for better ways", not only to inspire students but in everything you do. Stretching and searching for better ways is what life, science, chemistry, and teaching are all about, and it is a wonderfully stimulating and exciting way to approach anything and everything. Sometimes, though, one's ability to stretch is akin to that of a rubber band exposed too long to sunlight. Change becomes a threat or a burden instead of an opportunity. This often happens in one area but not others, as in the case of someone doing original research but whose lecture notes are yellow with age, or someone who experiments with new teaching approaches but neglects the latest chemical discoveries. Whatever its manifestation, failure to stretch and search for better ways is a great loss, both for the individual directly involved and for others. Fortunately there are many who continually stretch and search, often in conjunction with JCE. For example, some time ago the Chair of the Board of Publication, Jerry Bell, challenged Journal readers to become Journal

  10. Comparing One-Way and Two-Way Coupled Hydrometeorological Forecasting Systems for Flood Forecasting in the Mediterranean Region

    Directory of Open Access Journals (Sweden)

    Amir Givati

    2016-05-01

    Full Text Available A pair of hydro-meteorological modeling systems were calibrated and evaluated for the Ayalon basin in central Israel to assess the advantages and limitations of one-way versus two-way coupled modeling systems for flood prediction. The models used included the Hydrological Engineering Center-Hydrological Modeling System (HEC-HMS model and the Weather Research and Forecasting (WRF Hydro modeling system. The models were forced by observed, interpolated precipitation from rain-gauges within the basin, and with modeled precipitation from the WRF atmospheric model. Detailed calibration and evaluation was carried out for two major winter storms in January and December 2013. Then, both modeling systems were executed and evaluated in an operational mode for the full 2014/2015 rainy season. Outputs from these simulations were compared to observed measurements from the hydrometric station at the Ayalon basin outlet. Various statistical metrics were employed to quantify and analyze the results: correlation, Root Mean Square Error (RMSE and the Nash–Sutcliffe (NS efficiency coefficient. Foremost, the results presented in this study highlight the sensitivity of hydrological responses to different sources of simulated and observed precipitation data, and demonstrate improvement, although not significant, at the Hydrological response, like simulated hydrographs. With observed precipitation data both calibrated models closely simulated the observed hydrographs. The two-way coupled WRF/WRF-Hydro modeling system produced improved both the precipitation and hydrological simulations as compared to the one-way WRF simulations. Findings from this study, as well as previous studies, suggest that the use of two-way atmospheric-hydrological coupling has the potential to improve precipitation and, therefore, hydrological forecasts for early flood warning applications. However, more research needed in order to better understand the land-atmosphere coupling mechanisms

    This article offers an overview of the different names for the Milky Way and the accompanying beliefs and myths, based on the material in the Estonian Folklore Archives. Astronomically speaking, the Milky Way is a big stellar system – a galaxy. All stellar systems of similar type are called galaxies. Our sun is a fairly common star, lying at the outskirts of the Galaxy. The core of the Galaxy is located in the Sagittarius Constellation where the Milky Way is widest and brightest, but i...

    , in various ways, expertise plays an important part in creative processes. However, the case studies also indicate that expertise sometimes leads to an entrenched perspective, in the sense that knowledge and experience may work as a path into the well-known rather than into the unknown. In this article......, these issues are explored with reference to different theoretical approaches to creativity and learning, including actor-network theory, the theory of blind variation and selective retention, and Csikszentmihalyi’s system model. Finally, some educational aspects and implications of this are discussed....

    2000-01-01

    Most of the matter in the Milky Way is invisible to astronomers. Precise numbers are elusive, but it appears that the dark component is 20 times as massive as the visible disk of stars and gas. This dark matter is distributed in space differently than the stars, forming a vast, diffuse halo, more spherical than disklike, which occupies more than 1000 times the volume of the disk of stars. The composition of this dark halo is unknown, but it may comprise a mixture of ancient, degenerate dwarf stars and exotic, hypothetical elementary particles.

    2012-02-01

    Full Text Available The formation of the Milky Way in the currently accepted concordance cosmology presents a couple of pitfalls. Mostly, these involve the much reported overcooling problem. If gas is allowed to cool, it will condense into massive central concentrations unlike any observed in real galaxies. These concentrations are characterized by a high central peak in the rotation curve and a rise in the surface brightness profile much steeper than the exponentially increasing disk. Such galaxies may contain no disk component and form many more stars than predicted by abundance matching studies.

    Full Text Available This paper describes the “strucplot” framework for the visualization of multi-way contingency tables. Strucplot displays include hierarchical conditional plots such as mosaic, association, and sieve plots, and can be combined into more complex, specialized plots for visualizing conditional independence, GLMs, and the results of independence tests. The framework’s modular design allows flexible customization of the plots’ graphical appearance, including shading, labeling, spacing, and legend, by means of “graphical appearance control” functions. The framework is provided by the R package vcd.

  20. Ant navigation: one-way routes rather than maps.

    Wehner, Rüdiger; Boyer, Martin; Loertscher, Florian; Sommer, Stefan; Menzi, Ursula

    2006-01-10

    In recent years, there has been an upsurge of interest and debate about whether social insects-central-place foragers such as bees and ants-acquire and use cognitive maps, which enable the animal to steer novel courses between familiar sites . Especially in honey bees, it has been claimed that these insects indeed possess such "general landscape memories" and use them in a "map-like" way . Here, we address this question in Australian desert ants, Melophorus bagoti, which forage within cluttered environments full of nearby and more distant landmarks. Within these environments, the ants establish landmark-based idiosyncratic routes from the nest to their feeding sites and select different one-way routes for their outbound and inbound journeys. Various types of displacement experiments show that inbound ants when hitting their inbound routes at any particular place immediately channel in and follow these routes until they reach the nest, but that they behave as though lost when hitting their habitual outbound routes. Hence, familiar landmarks are not decoupled from the context within which they have been acquired and are not knitted together in a more general and potentially map-like way. They instruct the ants when to do what rather than provide them with map-like information about their position in space.

  2. Improving Formwork Engineering Using the Toyota Way

    2011-07-01

    Full Text Available Construction is a labor-intensive industry with formwork engineering requiring a disproportionate amount of labor and costs. Formwork accounts for approximately one-third of the cost of reinforced concrete construction, partly because traditional formwork processes frequently result in delivery delays and material waste. The purpose of this research is to adapt production concepts pioneered by Toyota (the “Toyota Way” to improve formwork engineering. The Toyota Way of production consists of four tiers of management philosophy, known as the “4Ps” model. This research adopts the 4Ps as steps for formwork improvement. The first step, “establishing long term vision,” emphasizes long term considerations for formwork improvement. Step two, “establishing value streams,” reviews formwork flows and eliminates wastage. The third step, “developing the crew,” forms mold workers as a team. The final step is “developing a culture of continuous improvement” that provides a basis for constant review and provides a basis for continuous progress. The present research used the Toyota Way to improve formwork engineering. The improvements include reductions in resource waste and increases in operational value. In the long run, the proposed model could provide a learning and growth platform for individuals, the business unit, and the company’s extended network of partners. It could also serve to spur innovative thinking in the improvement of formwork engineering.

  3. Ways of learning: Observational studies versus experiments

    Shaffer, T.L.; Johnson, D.H.

    2008-01-01

    Manipulative experimentation that features random assignment of treatments, replication, and controls is an effective way to determine causal relationships. Wildlife ecologists, however, often must take a more passive approach to investigating causality. Their observational studies lack one or more of the 3 cornerstones of experimentation: controls, randomization, and replication. Although an observational study can be analyzed similarly to an experiment, one is less certain that the presumed treatment actually caused the observed response. Because the investigator does not actively manipulate the system, the chance that something other than the treatment caused the observed results is increased. We reviewed observational studies and contrasted them with experiments and, to a lesser extent, sample surveys. We identified features that distinguish each method of learning and illustrate or discuss some complications that may arise when analyzing results of observational studies. Findings from observational studies are prone to bias. Investigators can reduce the chance of reaching erroneous conclusions by formulating a priori hypotheses that can be pursued multiple ways and by evaluating the sensitivity of study conclusions to biases of various magnitudes. In the end, however, professional judgment that considers all available evidence is necessary to render a decision regarding causality based on observational studies.

  4. The Long Way of Knowledge Society

    Full Text Available I think, therefore I am. Our ancestors said Cogito, ergo sum, in a Latin form of Rene Descartes' expression "Je pense, donc je suis", in Discourse on Method (1637. The same did Thomas Davenport, when gave his book the title Thinking for a living. Probably he didn't prefer the direct form in English of the above mentioned expression: "I think, therefore I am", but one that in essence is more poetical and more anchored in the reality of the third millennium's early days, in the way that only thinking we can exist. The title is also a commercial one, because the previous ten books also basically referred to knowing or knowledge. They used the research done in the following fields: knowledge management, process management and innovation. The opening of his last book, a best seller of 2005, is also interesting. The author gives the first chapter the title 'What's a Knowledge Worker, Anyway?". We could draw the conclusion that after so much effort, including a publishing one, the author remains with the doubt on the terminology so much used at the end of the 2nd millennium and the beginning of the 3rd one or leaves an open way to the next volumes. It is not by chance that there are voices that say he might be the next Peter Drucker. The last one said that the future society would be the knowledge society (see also Managing in the Next Society, 2002.

    2003-11-01

    Computer-enhanced learning as noted by Cole and Todd (5) is “somewhat less effective at the precollege level” (p 1339). Progress is slow due to a number of factors, including instructors who are resistant to change, the complexity of the subject, and the handling of chemistry laboratories. Many of our students politely go through the motions but are not actively engaged with the lesson. Simply listening to chemistry lectures may provide students with little in the way of substantial learning gains, because lectures do not necessarily actively involve students in the activity (9), yet with the incorporation of today’s technology into our curriculum and the flexible, asynchronous environment of online learning with the advantages immediate feedback provides (6) many students will expand their knowledge and skills. Careful monitoring by the instructor and setting of internal deadlines for students involved in online learning are known to encourage higher completion rates than are generally reported (10). We should take advantage of today’s advances, embrace them, and be the ones to change—set the pace and avoid the trap of “it’s not the way I learned to do it!”

    Zoltowski, Carla B.

    This study investigated the qualitatively different ways which students experienced human-centered design. The findings of this research are important in developing effective design learning experiences and have potential impact across design education. This study provides the basis for being able to assess learning of human-centered design which will allow educational programs to determine their impact, and what aspects are most effective. Because the object of study was the variation of students' experiences human-centered design, a phenomenographic framework was used to guide the methodology of the study. The literature and research on service-learning and human-centered design informed the construction of the phenomenographic study and also provided ways to interpret the data and situate the results. Thirty-three student designers from a variety of academic contexts were interviewed using a semi-structured, open-ended approach in which they discussed concrete experiences "designing for others", and reflections and meanings associated with those experiences. Analysis of the data yielded seven qualitatively different ways in which the students experienced human-centered design, or categories of description. Logically related, the seven categories of description formed an outcome space that was two-dimensional with distinct, but not independent, axes. The critical differences among the categories provided the basis for developing their hierarchical relationship. Five of the categories were nested hierarchically. From less comprehensive to more comprehensive, those categories included: Human-centered design as "User as Information Source Input to Linear Process", "Keep Users' Needs in Mind", "Design in Context", "Commitment" and "Empathic Design". Two categories represented ways of experiencing human-centered design that were distinct: design was not human-centered, but "Technology-Centered" and human-centered design was not design, but "Service". In addition, this

    We study the strategic choice of compatibility between two initially incompatible network goods in a two-stage game played by an incumbent and an entrant firm. Compatibility may be achieved by means of a converter. We derive a number of results under different assumptions about the nature of the converter (one-way vs two-way), the existence of property rights and the possibility of side payments. With incompatibility, entry deterrence occurs for sufficiently strong network effects. In the cas...

  9. WAYS OF INCREASING THE VISIBILITY OF THE ROMANIAN RURAL TOURISM

    2016-11-01

    Full Text Available Romania has a remarkable natural heritage, with landscapes that are unique in the world and with villages still preserving the habits and traditions unaltered. Country’s potential for the practising the rural tourism is high, with fair chances of transforming villages that are less visible at the international level into actual emblematic destinations. As the urban pollution and organisational stress rise, the vacations in the rural area may be a plausible way of reinvigorating the spirit. However, the lack of visibility of the Romanian destinations requires that new promoting methods be identified. By the quality analysis carried out by the author in this article, new ways to increase the Romanian tourism visibility and to attract new tourists are argued. Aspects such as promotion by art, by thematic museums, with the help of opinion makers or by means of popular literature pieces have been considered. Thus, the potential methods of promoting the authentic Romanian village have been identified, assuming that each reference in the foreign press, cinema or other communication channel must be identified and exploited for the benefit of the Romanian tourism

    The recent discovery of a purported bone of the Milky Way, a dark cloud nicknamed Nessie, has provided us with new clues for mapping out the spiral structure of our galaxy. It turns out that Nessie may not be alone: a follow-up study has identified more bones, potentially making up a skeleton of the Milky Way that traces out the densest parts of its spiral arms.Inconvenient Vantage PointHow many spiral arms does the Milky Way have? Where are they located? What does the structure look like between the arms? It may seem surprising that these fundamental questions dont yet have clear answers. But because were stuck in the galaxys disk, were forced to piece together our understanding of the Milky Ways structure based primarily on measurements of position and radial velocity of structures within the galactic plane.The discovery of Nessie presents an intriguing new tool to identify the layout of the galaxy. Nessie is a very long, thin, infrared-dark filament that runs along the modeled position of the Scutum-Centaurus arm and is believed therefore to trace the structure of the arm. In a new study led by Catherine Zucker (University of Virginia, Harvard-Smithsonian Center for Astrophysics), the authors have searched for additional bones like Nessie, hoping to use them to map out the skeleton of the Milky Way.New Bones DiscoveredIn this map of radial velocity vs. galactic longitude, the bone candidates are indicated by the numbered points. The colored lines indicate the positions of two of the galactic spiral arms, according to various models. Click for a closer look!

    2017-01-01

    This book offers a platform for engineering educators who are interested in implementing a “creative ways of knowing” approach to presenting engineering concepts. The case studies in this book reveal how students learn through creative engagement that includes not only design and build activities, but also creative presentations of learning, such as composing songs, writing poems and short stories, painting and drawing, as well as designing animations and comics. Any engineering educator will find common ground with the authors, who are all experienced engineering and liberal arts professors, who have taken the step to include creative activities and outlets for students learning engineering. • Demonstrates various methods for returning to the basics of engineering education, which include design and creativity, teamwork and interdisciplinary thinking; • Discusses a timely topic, as higher education puts more attention on the student experience of learning in all disciplines; • Includes actual stude...

  12. Organization (Theory) as a Way of Life

    2015-01-01

    To the extent that ‘classical organization theory’ is seen to possess any enduring interest it is mainly as a historic artefact. The idea that the principles, axioms, adages and devices elaborated by its proponents any longer possess traction in the present is rarely countenanced. In contrast...... to this customary view, the present article seeks to indicate the continuing significance of classical organization theory, for both analysing and intervening in organizational life. This necessitates a reconstruction of the conventional understanding of this received term, one in which classical organization......, not least, an ethical focus on organizational effectiveness born of a close connection to ‘the work itself’ or ‘the situation at hand’. Deploying the term ‘classic organization theory’ in this way, to refer to a stance, attitude or comportment, and an associated persona that bears it, we are able...

  13. Downsizing: Is There a "Right" Way?

    Tippett, Donald D.; Childress, Rhonda; Sweitzer, Melissa G

    1998-01-01

    In response to the pressures of surviving in in a competitive global market, many companies are turning to downsizing, right sizing, restructuring, reduction-in-force, and/or business process re-engineering, among others. Regardless of the terminology used, an inevitable result is a loss of jobs. Companies fail to grasp the profound ramifications of downsizing for both the people laid off and the organization and work force that remain after downsizing is complete. A search of the literature was conducted to ascertain what leading theorists and practitioners are saying about downsizing and the "right" way to go about it. This search culminated in the Nine Point Model for Downsizing (NPMD). The model is used to analyze a downsizing case study involving the December 1997 layoff of 19.000 employees by a leading manufacturer of imagine products.

    Full Text Available The article is devoted to the phenomenon of the Soviet architecture of the late 1950s – 60s. The name of the article is “Their name is halfway”. It expresses the sense of all the processes occurring both in society and architecture during the Khrushchev Thaw. Developing the socalled Stalin’s Empire in the 1930-1950s, the masters of architecture had travelled only half the way. If the power had not abruptly stopped this movement, we would probably have a unique modern architecture dissimilar to the “international style”. The collapse of the Soviet Union stopped the evolution of architecture again: the unique features of the Soviet architecture of the 1960s ceased to develop. Architects were carried away with ironic games of postmodernism, which led them to deadlock.

  15. Foucault's Three Ways of Decentering the State

    DEFF Research Database (Denmark)

    Villadsen, Kaspar

    It is well known that Michel Foucault challenged the centrality of the state, advancing a view of the state as ‘decentered’. He said: “The state has no heart, as we well know, but not just in the sense that it has no feelings, either good or bad, but it has no heart in the sense that it has...... no interior” (Foucault, 2008: 90). In the stream of scholarship inspired by Foucault it has become an interpretative orthodoxy that the state should be viewed as decentered, without a unifying center, resting upon networks of mobile power relations. In this way, political decision making is delocalized......, and sovereignty is dissolved in dispersed and mundane practices. Here, I wish to examine the three routes by which Foucault during the 1970s reached his renowned ‘decentered’ approach to the state. These routes never arrived at any ultimate conception of the state, since they were experimental explorations...

    VLT Observations of Beryllium in Two Old Stars Clock the Beginnings Summary Observations by an international team of astronomers [1] with the UVES spectrometer on ESO's Very Large Telescope at the Paranal Observatory (Chile) have thrown new light on the earliest epoch of the Milky Way galaxy. The first-ever measurement of the Beryllium content in two stars in a globular cluster (NGC 6397) - pushing current astronomical technology towards the limit - has made it possible to study the early phase between the formation of the first generation of stars in the Milky Way and that of this stellar cluster. This time interval was found to amount to 200 - 300 million years. The age of the stars in NGC 6397, as determined by means of stellar evolution models, is 13,400 ± 800 million years. Adding the two time intervals gives the age of the Milky Way, 13,600 ± 800 million years. The currently best estimate of the age of the Universe, as deduced, e.g., from measurements of the Cosmic Microwave Background, is 13,700 million years. The new observations thus indicate that the first generation of stars in the Milky Way galaxy formed soon after the end of the ~200 million-year long "Dark Ages" that succeeded the Big Bang.

    2006-01-01

    In the last decade extra-galactic planetary nebulae (PNe) have gained increasing importance. Improved observational capabilities have allowed fainter and fainter PNe to be studied in galaxies well beyond the Milky Way. Planetary nebulae can be detected to at least 30Mpc. They are found in galaxies of all types and also between the galaxies in nearby galaxy clusters. They are valuable as probes, both for providing the velocity of their host stars and also the evolutionary status and relation to the stellar population from which they formed. This book contains the proceedings of a workshop held at ESO headquarters in Garching in 2004, the first meeting devoted entirely to Extra-galactic Planetary Nebulae. A wide range of topics is covered, from stellar and nebular astrophysics to galactic dynamics and galaxy clusters, making this volume a unique and timely reference of broad astrophysical interest.

    Beebe, John

    2005-02-01

    Accepting the common lay definition of nightmare as any form of upsetting, dreamlike cognition occurring in the midst of sleep, the author argues for a classification of nightmares that would be based, not on physiological findings, but on what the upsetting nocturnal occurrence turns out to mean to the dreamer. Three types of nightmare identified on this basis are illustrated through dream sequences from classic Hollywood movies and amplified by clinical examples: (1) the dream that symbolizes the next stage of life as unusually daunting, (2) the dream that exposes the shadow of another person in a shocking way, and (3) the 'empathy dream', in which the dreamer experiences directly the anxieties of another subject. It is suggested that the accurate interpretation of a particular upsetting dream depends upon which type of nightmare the dream turns out to be.

  19. Relay Selection and Resource Allocation in One-Way and Two-Way Cognitive Relay Networks

    KAUST Repository

    Alsharoa, Ahmad M.

    2013-05-08

    In this work, the problem of relay selection and resource power allocation in one- way and two-way cognitive relay networks using half duplex channels with different relaying protocols is investigated. Optimization problems for both single and multiple relay selection that maximize the sum rate of the secondary network without degrading the quality of service of the primary network by respecting a tolerated interference threshold were formulated. Single relay selection and optimal power allocation for two-way relaying cognitive radio networks using decode-and-forward and amplify-and-forward protocols were studied. Dual decomposition and subgradient methods were used to find the optimal power allocation. The transmission process to exchange two different messages between two transceivers for two-way relaying technique takes place in two time slots. In the first slot, the transceivers transmit their signals simultaneously to the relay. Then, during the second slot the relay broadcasts its signal to the terminals. Moreover, improvement of both spectral and energy efficiency can be achieved compared with the one-way relaying technique. As an extension, a multiple relay selection for both one-way and two-way relaying under cognitive radio scenario using amplify-and-forward were discussed. A strong optimization tool based on genetic and iterative algorithms was employed to solve the 
formulated optimization problems for both single and multiple relay selection, where discrete relay power levels were considered. Simulation results show that the practical and low-complexity heuristic approaches achieve almost the same performance of the optimal relay selection schemes either with discrete or continuous power distributions while providing a considerable saving in terms of computational complexity.

  1. The Analysis of Two-Way Functional Data Using Two-Way Regularized Singular Value Decompositions

    KAUST Repository

    Huang, Jianhua Z.

    2009-12-01

    Two-way functional data consist of a data matrix whose row and column domains are both structured, for example, temporally or spatially, as when the data are time series collected at different locations in space. We extend one-way functional principal component analysis (PCA) to two-way functional data by introducing regularization of both left and right singular vectors in the singular value decomposition (SVD) of the data matrix. We focus on a penalization approach and solve the nontrivial problem of constructing proper two-way penalties from oneway regression penalties. We introduce conditional cross-validated smoothing parameter selection whereby left-singular vectors are cross- validated conditional on right-singular vectors, and vice versa. The concept can be realized as part of an alternating optimization algorithm. In addition to the penalization approach, we briefly consider two-way regularization with basis expansion. The proposed methods are illustrated with one simulated and two real data examples. Supplemental materials available online show that several "natural" approaches to penalized SVDs are flawed and explain why so. © 2009 American Statistical Association.

    Full Text Available Welcome to the first issue of our 5th volume of Evidence Based Library and Information Practice. And what an issue it is! We are very pleased to showcase the keynote addresses from the 5th International Evidence Based Library and Information Practice (EBLIP5 conference that took place in Stockholm, Sweden in July 2009. Andrew Booth, who was Chair of the International Program Committee for the conference, kindly agreed to take on a guest editorial role in gathering these keynote presentations together. I believe it is the first time the EBLIP community has been able to have the keynote papers from an EBLIP conference gathered in this way. Reading these commentaries will give you a true sense of the themes and questions that were woven throughout the conference and will give you lots to think about. For a fuller description and to put this Feature section in context, please be sure to read Andrew’s editorial at the beginning of the section.As we begin our fifth year of publication, submissions of original research articles continue to grow. In this issue we have five original articles on topics ranging from information literacy instruction to cataloguing of e‐books. Two articles look at using communities of practice in the support of evidence based practice; clearly this is an area of emerging research within EBLIP that readers will benefit from learning more about. One of these articles, by Urquhart, Brice, Cooper, Spink, and Thomas, won the Best Oral Presentation award at the EBLIP5 conference.In addition to the original research articles, we also have seven evidence summaries, covering topics such as unionization, information seeking behaviour, and the LIS blogosphere. The EBL101 column tackles critical appraisal, a daunting task that will not seem quite so scary once you’ve read the column!

  3. Chandra Catches Milky Way Monster Snacking

    For the first time astronomers have detected material being consumed by the supermassive black hole in our own backyard. A violent, rapid X-ray flare, captured by NASA's Chandra X-ray Observatory, has been observed from the direction of the supermassive black hole that resides at the center of our Milky Way Galaxy. A team of scientists, led by Fredrick K. Baganoff of the Massachusetts Institute of Technology (MIT) in Cambridge, detected a sudden X-ray flare while observing Sagittarius A*, a source of radio emission believed to be associated with the black hole at the center of our Galaxy. "This is extremely exciting because it's the first time we have seen our own neighborhood supermassive black hole devour a chunk of material," Baganoff said. "It's as if the material there sent us a postcard before it fell in." In a few minutes, the source brightened dramatically, eventually reaching a level 45 times brighter than before the flare. After about three hours, the X-ray intensity rapidly declined to the pre-flare level. "The rapid rise and fall of the X-rays from this outburst are compelling evidence that the X-ray emission is coming from matter falling into a supermassive black hole, confirming that it is powered by the same accretion process as quasars and other active galactic nuclei," said Baganoff. Baganoff added that the data also provide the best look yet at the area just outside this event horizon, the surface of "no return" for matter or light falling into a black hole. Studies of the central region of our Milky Way Galaxy in the infrared and radio wavebands indicate the presence of a large, dark object, presumably a supermassive black hole, having the mass of about 3 million suns. The faintness of Sagittarius A* at all wavelengths, especially in X-rays, has puzzled scientists who expected that the infalling matter should shine more brightly on its way in, and this has left some room for doubt. The latest precise Chandra observations of the crowded galactic

    This fascinating book examines some of the characteristics of technological/engineering models that are likely to be unfamiliar to those who are interested primarily in the history and philosophy of science and mathematics, and which differentiate technological models from scientific and mathematical ones. Themes that will be highlighted include: • the role of language: the models developed for engineering design have resulted in new ways of talking about technological systems • communities of practice: related to the previous point, particular engineering communities have particular ways of sharing and developing knowledge • graphical (re)presentation: engineers have developed many ways of reducing quite complex mathematical models to more simple representations • reification: highly abstract mathematical models are turned into ‘objects’ that can be manipulated almost like components of a physical system • machines: not only the currently ubiquitous digital computer, but also older analogue dev...

    Some form of potential or "capacity" is often seen as evidence of human moral status. Opinions differ as to whether the potential of the embryo should be regarded as such evidence. In this paper, I discuss some common arguments against regarding the embryo's potential as a sign of human status, together with some less common arguments in favour of regarding the embryo's potential in this way.

    2016-12-01

    This review proposes a more optimistic view of Alzheimer's disease (AD), in contrast to that contributed by the ageing of the population and the failure of potentially curative therapies (vaccines and others). Treatment failure is likely due to the fact that AD gestates in the brain for decades but manifests in old age. This review updates the concept of AD and presents the results of recent studies that show that primary prevention can reduce the incidence and delay the onset of the disease. Half of all cases of AD are potentially preventable through education, the control of cardiovascular risk factors, the promotion of healthy lifestyles and specific drug treatments. These approaches could substantially reduce the future incidence rate of this disease. Copyright © 2016 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI). All rights reserved.

    The CRADA between Delphi Automotive Systems (Delphi; formerly General Motors - AC Delco, Systems) and Lockheed Martin Energy Research (LMER) on automotive catalysts was completed at the end of FY96, after a ten month, no-cost extension. The CRADA was aimed at improved performance and lifetime of noble metal based three-way-catalysts (TWC), which are the primary catalytic system for automotive emission control systems. While these TWC can meet the currently required emission standards, higher than optimum noble metal loadings are often required to meet lifetime requirements. In addition, more stringent emission standards will be imposed in the near future, demanding improved performance and service life from these catalysts. Understanding the changes of TWC conversion efficiency with ageing is a critical need in improving these catalysts. Initially in a fresh catalyst, the active material is often distributed on a very fine scale, approaching single atoms or small atomic clusters. As such, a wide range of analytical techniques have been employed to provide high spatial resolution characterization of the evolving state of the catalytic material.

    Full Text Available Today's population faces great difficulties in fish marketing, although it is very valuable food. The classic supply with fresh fish has little influence on its consumption, which is not remarkable anyhow. Therefore one shulud be reminded on the classic, almost forgotten, ways of fish processing that can substantially increase fish assortment and improve its distribution. After cleaning and cutting the fish (primary procedures in its processing, comes salting, after which the salted fish can become an end-product or it can be one of many semi-products in the fish production chain. The most common methods of fish salting are dry-salting, dry-wet-salting (Greek-Dalmatian and wet-salting (pickling. The aim of fish drying is its dehydratation. Our country has the experience of traditional drying, sun-drying and natural drying of fish. Each of these has its own special qualities, depending on the fish species and the drying temperature. Smoked fish gets a very distinctive and spicy aroma and a specific colour. There are two kinds of smoking - cold and warm - based on the smoke derived from burning some special trees or, lately, from smoke preparations. Marinades are old procedures of fish processing in acetic acid and specific spices which can be prepared cold, fried or cooked. Fish-roe of some specific fish species has a special value and is considered a delicacy. The most precious black caviar is derived from the sturgeon roe and some of its related species.

    2008-12-01

    Full Text Available This paper describes how analogue switched circuits (switched-capacitor and switched-current circuits can be optimized by means of a personal computer. The optimization of this kind of circuits is not so common and their analysis is more difficult in comparison with continuously working circuits. Firstly, the nonidealities occurring in these circuits whose effect on their characteristics should be optimized are discussed. Then a few ways to analyze analogue switched circuits are shown. From all optimization algorithms applicable for this kind of optimization, two ones that seem to be the most promising are proposed. The differential evolution (one of evolutionary algorithms combined with the simplex method was found to be most appropriate from these two ones. Two types of programs are required for the optimization of these circuits: a program for implementing calculations of the used optimization algorithm and a program for the analysis of the optimized circuit. Several suitable computer programs from both of the groups together with their proper settings according to authors’ experience are proposed. At the end of the paper, an example of a switched-current circuit optimization documenting the previous description is presented.

    1995-11-01

    This presentation is a report of the testing activities of the CableLabs Network Integrity Working Group. The working group consisted of several CableLabs member companies which conducted rf analog and digital bit-error testing at five CATV networks in the U.S. and Canada. The purpose of the working group was to measure the reliability and availability of the contemporary CATV network as specified by traditional switched access telephony performance parameters. Transmission data was collected for both forward and reverse (sub- split) paths of the rf broadband network, in both traditional and hybrid fiber/coax architectures, and for baseline and controlled variation events. The basic premise of this testing was to ascertain which cable television network elements adversely affected transmission of a 'generic' digital communications system and how they can be managed or controlled. The digital transmission utilized in the test was a QPSK modulated, T-1 rate (1.544 Mbit/second), modem without error correction. The intent was not to derive the necessary modulation technique and error correction scheme to properly operate in every cable television system, but rather to determine the principal sources of impairments existing in these networks and deduce corrective measures. The full report of the Network Integrity Working Group is published by CableLabs, Inc., and is titled, 'Two-Way Cable Television System Characterization -- Final Report', April 1995.

    Simulations of tidal streams show that close encounters with dark matter subhaloes induce density gaps and distortions in on-sky path along the streams. Accordingly, observing disrupted streams in the Galactic halo would substantiate the hypothesis that dark matter substructure exists there, while in contrast, observing collimated streams with smoothly varying density profiles would place strong upper limits on the number density and mass spectrum of subhaloes. Here, we examine several measures of stellar stream 'disruption' and their power to distinguish between halo potentials with and without substructure and with different global shapes. We create and evolve a population of 1280 streams on a range of orbits in the Via Lactea II simulation of a Milky Way-like halo, replete with a full mass range of Λcold dark matter subhaloes, and compare it to two control stream populations evolved in smooth spherical and smooth triaxial potentials, respectively. We find that the number of gaps observed in a stellar stream is a poor indicator of the halo potential, but that (I) the thinness of the stream on-sky, (II) the symmetry of the leading and trailing tails and (III) the deviation of the tails from a low-order polynomial path on-sky ('path regularity') distinguish between the three potentials more effectively. We furthermore find that globular cluster streams on low-eccentricity orbits far from the galactic centre (apocentric radius ˜30-80 kpc) are most powerful in distinguishing between the three potentials. If they exist, such streams will shortly be discoverable and mapped in high dimensions with near-future photometric and spectroscopic surveys.

    We use 30 high-resolution dark matter haloes of the Caterpillar simulation suite to probe the first stars and galaxies of Milky Way-mass systems. We quantify the environment of the high-z progenitors of the Milky Way and connect them to the properties of the host and satellites today. We identify the formation sites of the first generation of Population III (Pop III) stars (z ˜ 25) and first galaxies (z ˜ 22) with several different models based on a minimum halo mass. This includes a simple model for radiative feedback, the primary limitation of the model. Through this method we find approximately 23 000 ± 5000 Pop III potentially star-forming sites per Milky Way-mass host, though this number is drastically reduced to ˜550 star-forming sites if feedback is included. The majority of these haloes identified form in isolation (96 per cent at z = 15) and are not subject to external enrichment by neighbouring haloes (median separation ˜1 kpc at z = 15), though half merge with a system larger than themselves within 1.5 Gyr. Using particle tagging, we additionally trace the Pop III remnant population to z = 0 and find an order of magnitude scatter in their number density at small (i.e. r 50 kpc) galactocentric radii. We provide fitting functions for determining the number of progenitor minihalo and atomic cooling halo systems that present-day satellite galaxies might have accreted since their formation. We determine that observed dwarf galaxies with stellar masses below 104.6 M⊙ are unlikely to have merged with any other star-forming systems.

    Full Text Available In India, HIV prevention and control activities started way before the reporting of the first case of HIV infection. On reporting of evidences of HIV infection from different parts of the country and varied groups, Government launched the National AIDS Control Program (NACP. The program was launched on the foundation of early interventions and Mid-Term Plan, which evolved in three phases over the period of eighteen years. With progression of time, epidemiological situation changed and knowledge/capacity to tackle HIV improved. In the course of the evolution, NACP has moved from the centrally controlled program to district driven. Also different strategies were inducted/refined and many important institutes like Task Force, a high-powered National AIDS Committee, National AIDS Control Board, National AIDS Control Organization, State AIDS Control Societies, Project Support Units/Project Management Units, National Council on AIDS, Department of AIDS Control, Technical Support Unit, District AIDS Prevention and Control Unit (DAPCU were created. Currently program is implemented vertically with good impetus and is able to contain the spread of HIV in India. For enhancing the effectiveness and sustainability, future of the NACP is strongly linked with the well-performing DAPCU and good synergy/integration with General Health System. HIV/AIDS epidemic in India has entered into the third decade. Evidences show that this epidemic in India is of concentrated type and characterized by the heterogeneity, following the type 4 pattern, where the epidemic shifts from the most vulnerable populations [such as female sex workers, men who have sex with men, injecting drug users to bridge populations (clients of sex workers, sexually transmitted infection patients, partners of drug users, long route truck drivers, short stay cyclical single male migrants], then to the general population and from urban centers to rural areas (ruralization of epidemic with increasing

    This statement from the President of the 31st December Women's Movement in Ghana was part of a larger text presented at the World NGO Conference in Tokyo, July 1-4, 1990. The women's movement in Ghana strives to achieve equal opportunity, social justice, and sustainable development against social discrimination for women. Planning and development have focused on women in socioeconomic development. Specific projects at the core of creating positive conditions for socioeconomic growth, raising the standard of living, and expanding the economy, involve cover food and cash-crop production, food processing, food preparation, and small scale industrial activities such as ceramics and crafts. Income supplementation helps parents to send children to school instead of work. Daycare centers operating near work places benefit mothers in terms of providing a vacation, adult literacy programs, and family counseling sessions. The Movement actively mobilizes women to have children vaccinated. Access to credit for women and utilization of technology enriches life for women, and reduces backbreaking labor. The Movement is building wells in rural areas to reduce parasitic infection and creating easy access to a water supply. 252 projects have been completed and 100 are in process. The Movement provides a development model for integrating the resources of government, NGO's, and members of the community. Self-confidence of women has assured the success of projects. The Sasakawa Foundation has contributed technology and Japanese volunteers to improve the cultivation of food crops and by example express humble, respectful, hard working, and happy models of big things staring in small ways.

    The present paper analyses two cases exemplifying a possible use of survey and its elaborations in the field of conservation: the bell tower of the Basilica Santa Maria delle Vigne and the Chiesa di San Matteo, both situated in Genoa. In the first case, the threedimensional survey was used as a basis to build a model for the structural analysis. The need for an accurate database created with the three-dimensional survey allowed the research team to determine and highlight the critical points of the structure as the thickness of vaults and floors, the location of loads and the inclination of the walls. The data collected was used to create an accurate 3D model to be tested with simulations, in order to verify the stability of the bell tower when applying stress and limitations. In the second case, the three-dimensional survey was used as the basis for the collection, management and representation of the data derived from the survey on rising damp. The purpose was to test a dynamic data processing system that could be used as a tool to collect data on site as well as to access data remotely. By using software for three-dimensional representation and a node programming language, it was possible to define a system that offered dynamic viewing and was easy to use, through the use of chromatic scales and level curves, which can be generated starting from tables containing numerical data. Surveying, diagnostics, modelling and representation allow one to experiment with new ways of interaction within the common goal of conservation.

    2014-05-01

    Full Text Available It is now generally accepted that the ‘central genome dogma’ (i.e. a causal chain going from DNA to RNA to proteins and downstream to biological functions should be replaced by the ‘fluid genome dogma’, that is, complex feed-forward and feed-back cycles that interconnect organism and environment by epigenomic programing – and reprograming – throughout life and at all levels, sometimes also down the generations. The epigenomic programing is the net sum of interactions derived from own metabolism and microbiota as well as external factors such as diet, pharmaceuticals, environmental compounds, and so on. It is a growing body of results indicating that many chronic metabolic and degenerative disorders and diseases – often called ‘civilization diseases’ – are initiated and/or influenced upon by non-optimal epigenomic programing, often taking place early in life. In this context, the first 1,000 days of life – from conception into early infancy – is often called the most important period of life. The following sections present some major mechanisms for epigenomic programing as well as some factors assumed to be of importance. The need for more information about own genome and metagenome, as well as a substantial lack of adequate information regarding dietary and environmental databases are also commented upon. However, the mere fact that we can influence epigenomic health programing opens up the way for prophylactic and therapeutic interventions. The authors underline the importance of creating a ‘Human Gut Microbiota and Epigenomic Platform’ in order to facilitate interdisciplinary collaborations among scientists and clinicians engaged in host microbial ecology, nutrition, metagenomics, epigenomics and metabolomics as well as in disease epidemiology, prevention and treatment.

  19. How business schools lost their way.

    2005-05-01

    Business schools are facing intense criticism for failing to impart useful skills, failing to prepare leaders, failing to instill norms of ethical behavior--and even failing to lead graduates to good corporate jobs. These criticisms come not just from students, employers, and the media but also from deans of some of America's most prestigious B schools. The root cause oftoday's crisis in management education, assert Warren G. Bennis and James O'Toole, is that business schools have adopted an inappropriate--and ultimately self-defeating--model of academic excellence. Instead of measuring themselves in terms of the competence of their graduates, or by how well their faculty members understand important drivers of business performance, they assess themselves almost solely by the rigor of their scientific research. This scientific model is predicated on the faulty assumption that business is an academic discipline like chemistry or geology when, in fact, business is a profession and business schools are professional schools--or should be. Business school deans may claim that their schools remain focused on practice, but they nevertheless hire and promote research-oriented professors who haven't spent time working in companies and are more comfortable teaching methodology than messy, multidisciplinary issues--the very stuff of management. The authors don't advocate a return to the days when business schools were glorified trade schools. But to regain relevancy, they say, business schools must rediscover the practice of business and find a way to balance the dual mission of educating practitioners and creating knowledge through research.

    2007-11-01

    Executing complex initiatives like acquisitions or an IT overhaul requires a breadth of knowledge that can be provided only by teams that are large, diverse, virtual, and composed of highly educated specialists. The irony is, those same characteristics have an alarming tendency to decrease collaboration on a team. What's a company to do? Gratton, a London Business School professor, and Erickson, president of the Concours Institute, studied 55 large teams and identified those with strong collaboration despite their complexity. Examining the team dynamics and environment at firms ranging from Royal Bank of Scotland to Nokia to Marriott, the authors isolated eight success factors: (1) "Signature" relationship practices that build bonds among the staff, in memorable ways that are particularly suited to a company's business. (2) Role models of collaboration among executives, which help cooperation trickle down to the staff. (3) The establishment of a "gift culture," in which managers support employees by mentoring them daily, instead of a transactional "tit-for-tat culture", (4) Training in relationship skills, such as communication and conflict resolution. (5) A sense of community, which corporate HR can foster by sponsoring group activities. (6) Ambidextrous leadership, or leaders who are both task-oriented and relationship-oriented. (7) Good use of heritage relationships, by populating teams with members who know and trust one another. (8) Role clarity and task ambiguity, achieved by defining individual roles sharply but giving teams latitude on approach. As teams have grown from a standard of 20 members to comprise 100 or more, team practices that once worked well no longer apply. The new complexity of teams requires companies to increase their capacity for collaboration, by making long-term investments that build relationships and trust, and smart near-term decisions about how teams are formed and run.

They seek to discover new, complex molecules in interstellar space that may be precursors to life. The GBT and Molecules The Robert C. Byrd Green Bank Telescope and some molecules it has discovered. CREDIT: Bill Saxton, NRAO/AUI/NSF "Clouds like this one are the raw material for new stars and planets. We know that complex chemistry builds prebiotic molecules in such clouds long before the stars and planets are formed. There is a good chance that some of these interstellar molecules may find their way to the surface of young planets such as the early Earth, and provide a head start for the chemistry of life. For the first time, we now have the capability to make a very thorough and methodical search to find all the chemicals in the clouds," said Anthony Remijan, of the National Radio Astronomy Observatory (NRAO). In the past three years, Remijan and his colleagues have used the GBT to discover ten new interstellar molecules, a feat unequalled in such a short time by any other team or telescope. The scientists discovered those molecules by looking specifically for them. However, they now are changing their strategy and casting a wide net designed to find whatever molecules are present, without knowing in advance what they'll find. In addition, they are making their data available freely to other scientists, in hopes of speeding the discovery process. The research team presented its plan to the American Astronomical Society's meeting in St. Louis, MO. As molecules rotate and vibrate, they emit radio waves at specific frequencies. Each molecule has a unique pattern of such frequencies, called spectral lines, that constitutes a "fingerprint" identifying that molecule. Laboratory tests can determine the pattern of spectral lines that identifies a specific molecule. Most past discoveries came from identifying a molecule's pattern in

Whether going on foot to our office, the cafeteria or a building where colleagues work, we are much more in harm's way than as a driver sitting in the shell of steel that is a car. There are some 8000 people working on the different sites of CERN. That means 8000 potential pedestrians and 8000 reasons for trying to keep the roads safe. Whether behind the steering wheel or on a bike, we sometimes forget that the roadway is not just for vehicles. Pedestrians are also fully fledged road users with equal rights. That is why drivers must remain alert and take care not to block pedestrian crossings, pavements or access ways, and why special caution...

    Full Text Available Circular economy has been studied extensively both in Europe and worldwide. It is largely viewed as a potential strategy for societal development, aimed to increase prosperity while reducing dependence on raw materials and energy. Many businesses regard circular economy as a way to enhance economic growth and increase profits. Governments across the world actively engage in the discussion about the benefits of a transition to a circular economy and about its impact on employment, economic growth, and the environment. This paper aims to study the major issues of circular economy, to identify its advantages, and to offer an insight into the transition stage the Baltic States are undergoing today on their way to circular economy. It is stressed that the Baltic countries are not fully using the opportunities offered by a circular economy. For example, Latvia’s, Lithuania’s, and Estonia’s recycling rates are significantly below those of other European countries. The Baltics depend heavily on EU financial support. An increase in funding will contribute to the implementation of circular economy technologies.

Although reproducible research is progressing in several valuable ways, we suggest that recent increases in internet bandwidth and disk space, along with the availability of open-source and free-software licences for tools, enable another simple step to make research reproducible. In this article, we urge the creation of minimal virtual reference environments implementing all the tools necessary to reproduce a result, as a standard part of publication. We address potential problems with this approach, and show an example environment from our own work. © The Author 2014. Published by Oxford University Press.

    Many researchers within the social sciences, medicine, and humanities have examined the ways people talk and think about depression. In their research and published literature they have attempted to determine the theoretical frameworks and appropriate language for categorizing such concepts and understandings. Drawing from mental health and broader social science scholarship, in this article we examine three approaches to developing an inclusive understanding of depression experiences: explanatory models, exploratory maps, and illness narratives. Utilizing these terms in the analysis of a single dataset, we identified multiple conceptual terms with potential analytical validity. Furthermore, we argue that variable usage and meanings of these concepts among lay people might contribute to a shared understanding of depression between lay people and experts, and ultimately have positive consequences for clinical practice.

    Metabolomics is recognized as a powerful top‐down system biological approach to understand genetic‐environment‐health paradigms paving new avenues to identify clinically relevant biomarkers. It is nowadays commonly used in clinical applications shedding new light on physiological regulatory processes of complex mammalian systems with regard to disease aetiology, diagnostic stratification and, potentially, mechanism of action of therapeutic solutions. A key feature of metabolomics lies in its ability to underpin the complex metabolic interactions of the host with its commensal microbial partners providing a new way to define individual and population phenotypes. This review aims at describing recent applications of metabolomics in clinical fields with insight into diseases, diagnostics/monitoring and improvement of homeostatic metabolic regulation.

    Full Text Available In this paper, we first study the conversion of weighted two-way automata to one-way automata. We show that this conversion preserves the unambiguity but does not preserve the determinism. Yet, we prove that the conversion of an unambiguous weighted one-way automaton into a two-way automaton leads to a deterministic two-way automaton. As a consequence, we prove that unambiguous weighted two-way automata are equivalent to deterministic weighted two-way automata in commutative semirings.

  10. Maximizing the wildlife conservation value of road right-of-ways in an agriculturally dominated landscape.

    Robert A McCleery

    Full Text Available There has been a growing recognition that the narrow linear strips of uncultivated vegetation that lie between roads and agricultural crops, referred to as roadside right-of-ways or verges, can serve as areas for the conservation of wildlife. The features of right-of-ways that should influence the composition of wildlife communities vary considerably. Our goal was to determine what features of right-of-ways increased the conservation potential of right-of-ways for wildlife in a grassland system dominated by agricultural production. We sampled 100 right-of-ways for birds and 92 right-of-ways for small mammals in McDonough and Warren Counties in west-central Illinois. We found that the sizes of right-of-ways and the amount of traffic on the adjacent roads synergistically worked to influence wildlife communities. On roads with low traffic, avian species richness increased rapidly with increased right-of-way width, while on roads with high traffic, avian richness increased only slightly with increasing right-of-way widths. We found that wider roadside right-of-ways (preferably across the road from equally wide right-of-ways with thicker and taller vegetation had the greatest conservation value for birds and small mammals. The features that enhanced the conservation value of right-of-ways in our study area were uncommon. Efforts to create or enhance these features for the benefit of wildlife would likely face numerous obstacles. Nonetheless, from a grassland conservation perspective, working with stakeholders to implement specific strategies to enhance these often neglected areas may be an effective complement to purchasing and restoring conservation lands away from roads.

    Full Text Available Economics has hit the mainstream in the last decade with popular books like Freakonomics and The Undercover Economist reaching the masses. These authors have used their toolkits far beyond the narrow scope of money and finance and answered questions pertaining to anything from social policy to demographics to crime. Their appeal has largely been their ability to explain that small underlying forces can have major impacts, intended or otherwise, on many different areas of society. One recent book following this trend is Nudge, published in 2008 by University of Chicago academics Richard Thaler and Cass Sunstein. The book has attracted acclaim from both journals and the press, with The Financial Times naming it as one of the best business books for 2008. Nudge coins the term ‘choice architecture’, referring to the manner in which a range of alternatives is presented, which the authors contend is commonly overlooked as an integral part of many decisions we all face during the course of our day-to-day lives (1. When people take the time to judiciously research all alternatives before them, or use their reflective systems in the parlance of the book, they generally make objectively good decisions. Unfortunately, in practice people cannot or do not take the time to do so and instead use their automatic or gut thinking systems, leading to inferior outcomes. The first section of the book then compellingly demonstrates the evidence of its importance in a multitude of situations. There are many lessons to be learned along the way, applicable to both policy-makers and those who wish to critically examine some of their own choices in life. Among these, lessons is the fact that a large percentage of the population will stick with an easy default option without consideration of better alternatives, even when considering a life-altering decision such as retirement planning. There are even examples of people who fail to take advantage of subsidies to

    Sexual harassment among adolescents has long been neglected in Germany though it is frequent and leads to significant strain for the victims. In international studies, the prevalence of sexual harassment ranges from 10 to 80 % among students. For the development of sexual harassment individual as well as school based factors play a role. Different pathways lead to this problematic behaviour. The effect of new media in the development of sexual harassment cannot be estimated so far. Frequent consequences of sexual harassment in addition to school associated difficulties are unspecific somatic complaints. General practitioners and pediatricians are frequently consulted tn the first place. Recommendations for consultation and interventions are presented. © Georg Thieme Verlag KG Stuttgart · New York.

  15. Ruby laser-assisted depilation: The mode of action and potential ways of improved outcome

    Science.gov (United States)

    Topping, Adam Partington

    Aim - To improve efficacy and lessen side effects resulting from normal mode ruby laser (NMRL)-assisted depilation via a greater understanding of its mode of action and the development of novel methods of reducing associated epidermal damage. Employing a thermal imaging camera and ex vivo hair-bearing skin, the targets for the NMRL (pulse duration 900 musec and spot size 7 mm) were defined, the temperatures reached and the heat dissipation rates determined. Production of heat was confined to the hair follicles, with the peak temperatures reached varying considerably between hairs within the same treatment area and also between individuals. Histological assessment for a known indicator of cellular damage (p53 expression) identified the sites and extent of damage, which correlated with the peak temperatures measured. An energy meter was used to detect the penetration of NMRL light through ex vivo skin, which was found to be deeper than previously theorised. The black-haired mouse (C57B1/10) was assessed both macroscopically and histologically and found to be an acceptable animal model of NMRL depilation and associated epidermal damage. Attempts to reduce the epidermal damage by simply stopping the light reaching the epidermis using a chromophore block were assessed. Chromophore did indeed reduce the amount of epidermal damage detected in laser-irradiated ex vivo human skin, whereas in contrast it increased the wounding seen in the much thinner skin of the mouse. Nevertheless the mouse model showed that this technique did not affect the depilation efficacy. An alternative method of reducing epidermal damage using induction of the cells' intrinsic protective mechanisms (heat shock proteins, HSP) was assessed using cultured keratinocytes and the mouse model. Primarily, the sub-lethal temperature optimum for HSP expression in human keratinocytes was determined, then an in vitro model of NMRL-associated epidermal damage was established and the heat pre-treatment assessed. The temperature to precondition mouse skin was then determined and its protective capacity and effect on depilatory efficacy examined in vivo. In both models heat pretreatment was found to significantly protect from NMRL-associated damage whilst having no detectable affect on depilatory efficacy.

    1999-06-01

    The infectivity of Schistosoma bovis cercariae administered orally was evaluated in Sahelian goats. Compared to the percutaneous route, a single massive oral dose resulted in a worm burden and in fecal egg excretion reduced by one-half. Surprisingly, tissue egg counts were increased by more than 4-fold. Fecundity of individual female schistosomes was, therefore, markedly increased. When infective doses were administered weekly for 20 wk, both worm and egg burdens were doubled without modification of the individual worm pair fecundity. Repeated oral infections seem to have induced an acquired tolerance toward parasite antigens. These results confirm the epidemiologic relevance of the oral route in a host species inclined to become infected through drinking water rather than percutaneous exposures.

    A recent randomized controlled clinical trial of the immunostimulatory agent thymosin alpha-1 was conducted and showed a trend toward improved survival in patients receiving the drug (P = 0.06). Although this was a relatively small study and the exact mechanism of action of thymosin alpha-1 is not known, the present results further support the evolving concept that, as sepsis persists, a hypoinflammatory and immunosuppressive condition ensues and therapy that augments host immunity may be advantageous. Other immunomodulatory agents including granulocyte-macrophage colony-stimulating factor have shown promise in small trials in sepsis. In addition, there are a number of new immunoadjuvant agents such as IL-7 and anti-programmed cell death-1 that are showing remarkable abilities to enhance host immunity and improve outcomes in a variety of clinical disorders, including cancer and chronic viral infections. Animal studies show that these new immunoadjuvant agents improve survival in several clinically relevant models of sepsis. Given the relative safety of thymosin alpha-1 and these other new immunomodulatory agents as well as the persisting high mortality of sepsis, a strong case can be made for larger well-designed trials using immunoadjuvant therapy in patients who have documented immune suppression. Immunotherapy offers new hope in the treatment of sepsis and may dramatically change the face of the disease.

  1. The interaction of fingermark deposits on metal surfaces and potential ways for visualisation.

    The interaction of fingermark deposits on metals has been examined by a variety of techniques. Visualisation by film growth has been the main area of investigation through: thermal oxidation, anodising, peroxide solution, and the interaction with vapour of iodine and ammonium sulphide. Corrosion of the underlying metal has also been examined as an alternative means of visualisation. Confocal microscopy was used to look at the film thickness and corrosion products around the prints. Scanning electron microscopy and energy dispersion of X-rays (SEM-EDX) examined a number of metal samples to investigate film growth and the elemental distribution. The observations suggest that differential oxidation was occurring as well as corrosion into the metal. Fingermark deposits on metals can corrode into the metal depending on the reactivity of the metal and leave a recoverable mark. However, fingermark deposits can also alter the rate of chemical reaction of the substrate metal by oxidation. In some cases organic matter can inhibit reaction, both when forming an oxide layer and when corroding the metal. However, signs of third level detail from pore contact may also be visible and the monovalent ions from salts could also influence film growth. Whilst further work would need to be carried out to decide whether any of these techniques may have application in fingermark recovery, this study does suggest that fingermarks on metals may be recoverable after incidents such as fires or immersion in water.

    2017-03-01

    (99m)Tc, the most common radioisotope used in nuclear medicine, is produced in a nuclear reactor from the decay of (99)Mo. There are only a few aging nuclear reactors around the world that produce (99)Mo, and one of the major contributors, the National Research Universal (Canada), ceased production on October 31, 2016. The National Research Universal produced approximately 40% of the world's (99)Mo supply, so with its shut down, shortages of (99)Mo/(99m)Tc are expected. Methods: Nuclear pharmacies and nuclear medicine departments throughout the United States were contacted and asked to provide their strategies for coping with a shortage of (99)Mo/(99m)Tc. Each of these strategies was evaluated on the basis of its effectiveness for conserving (99m)Tc while still meeting the needs of the patients. Results: From the responses, the following 6 categories of strategies, in order of importance, were compiled: contractual agreements with commercial nuclear pharmacies, alternative imaging protocols, changes in imaging schedules, software use, generator management, and reduction of ordered doses or elimination of backup doses. Conclusion: The supply chain of (99)Mo/(99m)Tc is quite fragile; therefore, being aware of the most appropriate coping strategies is crucial. It is essential to build a strong collaboration between the nuclear pharmacy and nuclear medicine department during a shortage situation. With both nuclear medicine departments and nuclear pharmacies implementing viable strategies, such as the ones proposed, the amount of (99m)Tc available during a shortage situation can be maximized. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

    In our societies, we invest a lot of resources to ensure technological progress, and to find out secrets about the deepest corners of our universe. As a result, we are experiencing technological breakthroughs at an unprecedented rate, and we invest billions into research that is as far away from everyday life as the east is from the west. While technology has the potential to improve the quality of life and the satisfaction of curiosity is rewarding, we must not fail to notice that, at the same time, many of our societies are falling apart. Inequality all over the world has become staggering, and we are seriously failing to meet the most basic needs of the majority of people that live on this planet. We have neglected adverse societal changes for far too long, and we have done very little in terms of research to understand, and more importantly, to reverse, or at least to impede, these very worrying trends...

An effective ponderomotive potential is introduced accordingly and can capture nonadiabatic particle dynamics. We show that nonadiabatic ponderomotive barriers can trap classical particles, produce cooling effect, and generate one-way walls for resonant species. Possible atomic applications are also envisioned.

    Full Text Available In Maria Auxiliadora School, located in Villapinzón municipality, it is proposed a research work based on the principles of image pedagogy – a proposal aiming at the education of sensitivity of students’ way of looking in order to generate critical thinking development, broadening students’ horizons of self-knowledge as subjects of their own environment, of the complex media world around them, and of the globalized world related to that environment. Thus, this paper states the importance of the education of students’ way of looking at aspects that in daily life are overlooked, or that, even worse, are not understood. Then, some reflections concerning image reading, its importance in current society, the vertiginous way in which they develop, the need to integrate and take advantage of images as a knowledge tool and subject, the relevance of education towards analytic reading of implicit messages in the new codes imposed by media, and the overcoming of the dichotomy between text reading and image reading arise.

    2010-05-01

    The interactions among the ways of life and drink of youths indigenous of a populous place of Upper Rio Negro were analyzed through an ethnographic research. It was used a theoretical model that allowed to decompose and to articulate the social reality in different levels. It was observed that there was a multiplication of the situations in which is possible to drink, that are associated to mechanisms as much of belonging demarcation as of exposition of differences inter-group. Nowadays, youths insert themselves in multiple interaction networks. Through these networks they can create juvenile atmospheres of alcohol consumption, drink far away from the parents and buy industrialized drinks. With the introduction of the school and the abandonment of the initiation rituals, the youth status became uncertain, and it occurs in an ambiguous way the social norms of alcohol consumption, in a context in which there is no consensus in daily practice respect of the possible strategies to regulate juvenile drinking. Through this research, theoretical-methodological alternatives could be suggested to investigate the relationships that are established between the ways of life and the production of the health and disease, incorporating in this analysis the culture (and its transformation), the daily life (and its contradictions), the people (and its subjectivities).

  10. Galactoseismology: From The Milky Way To XUV Disks

    observations. By mapping to the HI image, the GALEX UV image, the multi-wavelength SED of XUV disks, as well as the masses and deprojected distances of the satellites in a statistically robust way using a Monte Carlo Markov Chain analysis, we will produce evolutionary histories of XUV disks and their satellite populations for the first time. This will enable an apples-to-apples comparison for XUV disks in the Local Volume. There is currently no study that has examined the morphological effects of satellites in cosmological simulations on the gas and stellar disk. This is a critical test of the distribution (the number, the mass, and orbits) of satellites in cosmological simulations. We will also investigate if the vast polar structure (VPOS) of dwarf galaxies around the Milky Way is a serious problem for the Lambda-CDM paradigm. Here we ask two simple questions: 1) Is the VPOS dynamically coherent? If the VPOS is a serious problem for Lambda-CDM, one expects that it should persist over a dynamical time and should not be unique to the present day. 2) Are there certain satellites that drive the appearance of the planar structure at present day? If so, it is critical to examine whether a sub-set excluding these satellites resembles cosmological simulations. Our preliminary results show that this structure is not dynamically coherent, and is driven by two satellites: Leo I and Leo II, both of which have extreme kinematic properties. We will also examine the evolution of the VPOS in non-spherical and time-dependent potentials. We will seek to obtain more accurate proper motions of Leo II in the upcoming HST cycle, as we find that Leo II particularly influences the fit to the planar structure. These results will have far-reaching impact in understanding data from many NASA missions - HST, GALEX, Spitzer, and Herschel to JWST and WFIRST missions. We will also provide a framework for understanding data from the GAIA and GALAH surveys of the Milky Way.

    Anthony John Garnello, Karina Paredes, Uyen Khanh Ho Trinh, Jin Wu, Scott Saleska Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, AZ, USA Abstract: Leaf age is an important characteristic for controlling plant functional performance and is associated with the changes of leaf physical, chemical, and physiological properties. Understanding how plant physiology changes over time will allow more accurate predictions of growth patterns, and a more comprehensive understanding of vegetative life histories. There still lacks an efficient technique in monitoring leaf age, tagging leaves is still the only way to accurately monitor leaf age. The goal of this study is to develop a multi-metric, accurate technique for better monitoring of leaf age. In order to acquire true leaf age records, 10 individual plant species were selected at the University of Arizona campus, and newly flushing leaves were tagged and monitored during the Monsoon season (from early June, 2013, to mid October, 2013). Every 2 weeks, 10 to 15 leaves in relative age order were harvested from each 1-meter branch to measure multiple key leaf metrics, including leaf thickness (via micrometer), fresh and dry weight, fresh and dry area (via ImageJ software), and leaf hyperspectral reflectance (via a handheld ASD Field Pro). Other leaf traits were also derived from our measurements, such as specific leaf area (SLA), leaf density (fresh weight/leaf volume), water percentage, and shrinkage ratio (1-dry area/fresh area). The hyperspectral version of vegetation index (a ratio derived from two spectral channels) was generated for each branch sample, by randomly selecting two channels from within the spectral domain of 350 nm to 2500 nm. The preliminary result documents three types of hyperspectral vegetation index (VI) which are highly related with leaf relative age order (R2>0.9). These include the sensitive spectral domains correlated with (a) leaf pigments (~550nm) and leaf physical

    2012-02-01

    Controlling locomotion and transport of microorganisms is a key challenge in the development of future biotechnological applications. Here, we demonstrate the use of optimized microfluidic ratchets to rectify the mean swimming direction in suspensions of the unicellular green alga Chlamydomonas reinhardtii, which is a promising candidate for the photosynthetic production of hydrogen. To assess the potential of microfluidic barriers for the manipulation of algal swimming, we studied first the scattering of individual C. reinhardtii from solid boundaries. High-speed imaging reveals the surprising result that these quasi-spherical ``puller''-type microswimmers primarily interact with surfaces via direct flagellar contact, whereas hydrodynamic effects play a subordinate role. A minimal theoretical model, based on run-and-turn motion and the experimentally measured surface-scattering law, predicts the existence of optimal wedge-shaped ratchets that maximize rectification of initially uniform suspensions. We confirm this prediction in experimental measurements with different geometries. Since the mechano-elastic properties of eukaryotic flagella are conserved across many genera, we expect that our results and methods are applicable to a broad class of biflagellate microorganisms.

    2007-01-01

    The new European Framework Programme - FP7 - has recently started and will offer various possibilities for CERN to participate in EU co-funded projects for research and technological development. In December 2006, the Council of the European Union (EU) formally adopted the 7th European Framework Programme for research, technological development and demonstration activities (FP7). FP7 started on 1 January 2007 and will cover the period 2007 to 2013. With a total budget of 50.5 B-Euros, FP7 is the largest Framework Programme in the history of the EU. FP7 consists of four major sub-programmes, referred to as 'Specific Programmes'. 'Cooperation' is focused on collaborative research and is divided into 10 research themes. 'Ideas' is a new EU programme for funding of frontier research in all fields of science. 'Capacities' aims at strengthening the research capacities in Europe. Finally, 'People' succeeds the previous Marie Curie Programmes and targets the development of Europe's human potential. On 22 December...

    Twenty-five to sixty percent of physicians report burnout across all specialties. Changes in the healthcare environment have created marked and growing external pressures. In addition, physicians are predisposed to burnout due to internal traits such as compulsiveness, guilt, and self-denial, and a medical culture that emphasizes perfectionism, denial of personal vulnerability, and delayed gratification. Professional coaching, long utilized in the business world, provides a results-oriented and stigma-free method to address burnout, primarily by increasing one's internal locus of control. Coaching enhances self-awareness, drawing on individual strengths, questioning self-defeating thoughts and beliefs, examining new perspectives, and aligning personal values with professional duties. Coaching utilizes established techniques to increase one's sense of accomplishment, purpose, and engagement, all critical in ameliorating burnout. Coaching presumes that the client already possesses strengths and skills to handle life's challenges, but is not accessing them maximally. Although an evidence base is not yet established, the theoretical basis of coaching's efficacy derives from the fields of positive psychology, mindfulness, and self-determination theory. Using a case example, this article demonstrates the potential of professional coaching to address physician burnout.

    Full Text Available Aim. The prostate tumor-inducing oncogene (PTI-1, presumably encoding a truncated form of eukaryotic translation elongation factor 1A1 (eEF1A1, was discovered as a gene overexpressed in prostate tumor samples and absent in normal tissues. The mechanism of PTI-1 oncogenicity remains obscure. Methods. Several bioinformatics methods were applied to analyze the PTI-1 mRNA structure, translation efficiency and coding potential. Results. In silico analysis of 5'UTR of its mRNA suggest that PTI-1 mRNA most probably belongs to the class of templates with low translation efficiency. Additionally, novel open reading frame (ORF starting with alternati- ve initiation site situated upstream of the main ORF start codon was found. Finally, the peptide that does not resemble eEF1A1 but is partially homologous to relaxin can be synthesized. Conclusions. We suggest that the alternative upstream start codon may initiate synthesis of a peptide (uPTI-1 homologous to relaxin, the hormone shown to promote the prostate cancer progression. uPTI-1 protein may interact with the respective relaxin-specific receptors, suggesting that the tumorigenic outcome of PTI-1 is possibly realized via the relaxin-dependent pathway.

    Salmonella enterica subspecies enterica includes several serovars infecting both humans and other animals and leading to typhoid fever or gastroenteritis. The high prevalence of associated morbidity and mortality, together with an increased emergence of multidrug-resistant strains, is a current global health issue that has prompted the development of vaccination strategies that confer protection against most serovars. Currently available systemic vaccine approaches have major limitations, including a reduced effectiveness in young children and a lack of cross-protection among different strains. Having studied host-pathogen interactions, microbiologists and immunologists argue in favor of topical gastrointestinal administration for improvement in vaccine efficacy. Here, recent advances in this field are summarized, including mechanisms of bacterial uptake at the intestinal epithelium, the assessment of protective host immunity, and improved animal models that closely mimic infection in humans. The pros and cons of existing vaccines are presented, along with recent progress made with novel formulations. Finally, new candidate antigens and their relevance in the refined design of anti-Salmonella vaccines are discussed, along with antigen vectorization strategies such as nanoparticles or secretory immunoglobulins, with a focus on potentiating mucosal vaccine efficacy.

  18. GM foods: is there a way forward?

    Science.gov (United States)

    Jones, Huw D

    2015-08-01

    There are many quality targets in cereals that could generate step-change improvements in nutritional or food-processing characteristics. For instance, levels of acrylamide, soluble and insoluble fibre, antioxidants, allergens and intolerance factors in food are, to a large extent, determined by the genetics of the raw materials used. However, improvements to these traits pose significant challenges to plant breeders. For some traits, this is because the underlying genetic and biochemical basis of the traits is not fully understood but for others, there is simply a lack of natural genetic variation in commercially useful germplasm. One strategy to overcome the latter hindrance is to use wide crosses with more exotic germplasm; however, this can bring other difficulties such as yield loss and linkage drag of deleterious alleles. As DNA sequencing becomes cheaper and faster, it drives the research fields of reverse genetics and functional genomics which in turn will enable the incorporation of desirable traits into crop varieties via molecular breeding and biotechnology. I will discuss the evolution of these techniques from conventional genetic modification to more recent developments in targeted gene editing and the potential of biotechnology to complement conventional breeding methods. I will also discuss the role of risk assessment and regulation in the commercialisation of GM crops.

    Full Text Available Jayashree A Chandrasekharan, Neelam Sharma-Walia HM Bligh Cancer Research Laboratories, Department of Microbiology and Immunology, Chicago Medical School, Rosalind Franklin University of Medicine and Science, North Chicago, IL, USAAbstract: An effective host defense mechanism involves inflammation to eliminate pathogens from the site of infection, followed by the resolution of inflammation and the restoration of tissue homeostasis. Lipoxins are endogenous anti-inflammatory, pro-resolving molecules that play a vital role in reducing excessive tissue injury and chronic inflammation. In this review, the mechanisms of action of lipoxins at the site of inflammation and their interaction with other cellular signaling molecules and transcription factors are discussed. Emphasis has also been placed on immune modulatory role(s of lipoxins. Lipoxins regulate components of both the innate and adaptive immune systems including neutrophils, macrophages, T-, and B-cells. Lipoxins also modulate levels of various transcription factors such as nuclear factor κB, activator protein-1, nerve growth factor-regulated factor 1A binding protein 1, and peroxisome proliferator activated receptor γ and control the expression of many inflammatory genes. Since lipoxins and aspirin-triggered lipoxins have clinical relevance, we discuss their important role in clinical research to treat a wide range of diseases like inflammatory disorders, renal fibrosis, cerebral ischemia, and cancer. A brief overview of lipoxins in viral malignancies and viral pathogenesis especially the unexplored role of lipoxins in Kaposi's sarcoma-associated herpes virus biology is also presented.

  20. 10 ways to create shareholder value.

    Science.gov (United States)

    Rappaport, Alfred

    2006-09-01

    Executives have developed tunnel vision in their pursuit of shareholder value, focusing on short-term performance at the expense of investing in long-term growth. It's time to broaden that perspective and begin shaping business strategies in light of the competitive landscape, not the shareholder list. In this article, Alfred Rappaport offers ten basic principles to help executives create lasting shareholder value. For starters, companies should not manage earnings or provide earnings guidance; those that fail to embrace this first principle of shareholder value will almost certainly be unable to follow the rest. Additionally, leaders should make strategic decisions and acquisitions and carry assets that maximize expected value, even if near-term earnings are negatively affected as a result. During times when there are no credible value-creating opportunities to invest in the business, companies should avoid using excess cash to make investments that look good on the surface but might end up destroying value, such as ill-advised, overpriced acquisitions. It would be better to return the cash to shareholders in the form of dividends and buybacks. Rappaport also offers guidelines for establishing effective pay incentives at every level of management; emphasizes that senior executives need to lay their wealth on the line just as shareholders do; and urges companies to embrace full disclosure, an antidote to short-term earnings obsession that serves to lessen investor uncertainty, which could reduce the cost of capital and increase the share price. The author notes that a few types of companies--high-tech start-ups, for example, and severely capital-constrained organizations--cannot afford to ignore market pressures for short-term performance. Most companies with a sound, well-executed business model, however, could better realize their potential for creating shareholder value by adopting the ten principles.

    Context. There have been conflicting results with respect to the extent that radial migration has played in the evolution of the Galaxy. Additionally, observations of the solar neighborhood have shown evidence of a merger in the past history of the Milky Way that drives enhanced radial migration. Aims: We attempt to determine the relative fraction of stars that have undergone significant radial migration by studying the orbital properties of metal-rich ([Fe/H] > 0.1) stars within 2 kpc of the Sun. We also aim to investigate the kinematic properties, such as velocity dispersion and orbital parameters, of stellar populations near the Sun as a function of [Mg/Fe] and [Fe/H], which could show evidence of a major merger in the past history of the Milky Way. Methods: We used a sample of more than 3000 stars selected from the fourth internal data release of the Gaia-ESO Survey. We used the stellar parameters from the Gaia-ESO Survey along with proper motions from PPMXL to determine distances, kinematics, and orbital properties for these stars to analyze the chemodynamic properties of stellar populations near the Sun. Results: Analyzing the kinematics of the most metal-rich stars ([Fe/H] > 0.1), we find that more than half have small eccentricities (e 7 kpc. We find that the highest [Mg/Fe], metal-poor populations have lower vertical and radial velocity dispersions compared to lower [Mg/Fe] populations of similar metallicity by 10 km s-1. The median eccentricity increases linearly with [Mg/Fe] across all metallicities, while the perigalacticon decreases with increasing [Mg/Fe] for all metallicities. Finally, the most [Mg/Fe]-rich stars are found to have significant asymmetric drift and rotate more than 40 km s-1 slower than stars with lower [Mg/Fe] ratios. Conclusions: While our results cannot constrain how far stars have migrated, we propose that migration processes are likely to have played an important role in the evolution of the Milky Way, with metal-rich stars

    To know the ways and means of comfort perceived by the older adults hospitalized in a medical service. Ethnographic study with a qualitative approach. We conducted semi-structured interviews with 22 older adults and participant observation of care situations. The ways and means of providing comfort are centered on strategies for promoting care mobilized by nurses and recognized by patients(clarifying/informing, positive interaction/communication, music therapy, touch, smile, unconditional presence, empathy/proximity relationship, integrating the older adult or the family as partner in the care, relief of discomfort through massage/mobilization/therapy) and on particular moments of comfort (the first contact, the moment of personal hygiene, and the visit of the family), which constitute the foundation of care/comfort. Geriatric care is built on the relationship that is established and complete with meaning, and is based on the meeting/interaction between the actors under the influence of the context in which they are inserted. The different ways and means of providing comfort aim to facilitate/increase care, relieve discomfort and/or invest in potential comfort.

  6. Joint Preprocesser-Based Detectors for One-Way and Two-Way Cooperative Communication Networks

    KAUST Repository

    Abuzaid, Abdulrahman I.

    2014-05-01

    Efficient receiver designs for cooperative communication networks are becoming increasingly important. In previous work, cooperative networks communicated with the use of L relays. As the receiver is constrained, channel shortening and reduced-rank techniques were employed to design the preprocessing matrix that reduces the length of the received vector from L to U. In the first part of the work, a receiver structure is proposed which combines our proposed threshold selection criteria with the joint iterative optimization (JIO) algorithm that is based on the mean square error (MSE). Our receiver assists in determining the optimal U. Furthermore, this receiver provides the freedom to choose U for each frame depending on the tolerable difference allowed for MSE. Our study and simulation results show that by choosing an appropriate threshold, it is possible to gain in terms of complexity savings while having no or minimal effect on the BER performance of the system. Furthermore, the effect of channel estimation on the performance of the cooperative system is investigated. In the second part of the work, a joint preprocessor-based detector for cooperative communication networks is proposed for one-way and two-way relaying. This joint preprocessor-based detector operates on the principles of minimizing the symbol error rate (SER) instead of minimizing MSE. For a realistic assessment, pilot symbols are used to estimate the channel. From our simulations, it can be observed that our proposed detector achieves the same SER performance as that of the maximum likelihood (ML) detector with all participating relays. Additionally, our detector outperforms selection combining (SC), channel shortening (CS) scheme and reduced-rank techniques when using the same U. Finally, our proposed scheme has the lowest computational complexity.

    2001-03-01

    Three-way component analysis techniques are designed for descriptive analysis of 3-way data, for example, when data are collected on individuals, in different settings, and on different measures. Such techniques summarize all information in a 3-way data set by summarizing, for each way of the 3-way data set, the associated entities through a few components and describing the relations between these components. In this article, 3-mode principal components analysis is described at an elementary level. Guidance is given concerning the choices to be made in each step of the process of analyzing 3-way data by this technique. The complete process is illustrated with a detailed description of the analysis of an empirical 3-way data set.

    2016-01-01

    This article deals with a typology of 45 techniques of humor that I found when doing research on the mechanisms that generate humor in texts, lists the techniques and applies them to a Jewish joke. It references the work of Vladimir Propp on folktales as analogous in that both are concerned with mechanisms in text that generate meaning. It also deals with four theories about why people find texts humorous, defines the joke as a short narrative with a punch line that is meant to generate mirthful laughter and defines Jewish humor as being about Jewish people and culture as told by Jewish people. It offers a paradigmatic analysis of the joke, and offers some insights into why Jewish people developed their distinctive kind of humor. This article is an enhanced and expanded version of an article which was published in a Chinese semiotics journal (doi:10.1515/css-2015-0022). PMID:27547262

    Full Text Available Abstract: The use of ICT in language education to enhance classroom-based instruction is examined in reference to blended learning. A blended model of integrating technological advances via an online lab with a face-to-face classroom environment is presented. The example of this operating in practice is iZone, a four-level print-digital series designed with the online component called MyiZoneLab at its heart, forming a cohesive and inseparable whole with its accompanying texts. Overcoming the limitations of classroom-only instruction is a particular strength of advances in computer technology. Delivering a unified body of content through different mediums is in effect a third way, neither just online nor simply in class, and this newer model has the capability to fully exploit and reinforce the advantages of each separate medium. Online access via a web browser may make good on the promise of studying whenever the learner desires, wherever they happen to be. To this movement towards flexibility in time and place is added a further ingredient, that of choice in self-study or learning with others, and of matching the time the individual spends on tasks to their needs. Integration and inseparability are inherent in this blended model, unleashing the potentiality of technological developments in language education while seeking to transcend the either online or face-to-face learning dichotomy.

    2015-01-01

    Understanding the molecular mechanism of the interaction of amphipathic and antimicrobial peptides with membranes is of fundamental interest, especially because of the potential of amphipathic peptides as therapeutics. The most studied amphipathic peptides in this context are certainly melittin, magainin and alamethicin, of which melittin is the only one to exhibit a powerful hemolytic and therefore toxic action. Herein we study the effect of the antimicrobial but hemolytic peptide melittin on the bending elasticity of giant unilamellar vesicles (GUVs). The results are compared to the effects of non-hemolytic amphipathic peptides such as alamethicin. We found that monomeric melittin acts very differently on the membrane mechanical properties. Strikingly, the difference is the most pronounced for low peptide concentrations, relevant for the hemolytic action. This gives some insight into the subtle nature of this peptide-membrane interaction. Furthermore, the results show that bending elasticity measurements might be a sensitive way to distinguish between lytic and non-lytic antimicrobial peptides. Copyright © 2014 Elsevier Ireland Ltd.

    Timothy Marshall, a failure and damage consultant with the Haag Engineering Company in Dallas, Texas, possesses a passion for storm chasing. On the afternoon of May 3, 1999, with atmospheric conditions creating a potentially explosive situation, Marshall drove several hours north to central Oklahoma to spot tornadoes. A storm started blowing up near Lawton and moved parallel to Interstate 44, with Marshall ahead of it in his Chevy pickup. He parked on the Newcastle overpass bridge, videotaping the long-tracked twister for later study At 7:04 p.m. local time, with the vortex now just one mile away and moving straight toward him, it started appearing three-dimensional, debris and projectiles flying about, the tornado roaring like freight trains, wind howling, red mud raining down, and things “getting a little out of hand,” Marshall recalled. He drove out of its path, only to watch the tornado tear through the suburban streets and houses of Moore, on its way to Oklahoma City.

In both studies the meanings ascribed to the downtown area of Joinville (a town with a population of 500 thousand, located in the northeast of Santa Catarina state and considered the third largest city of southern Brazil were analyzed, in particular the practices of design and typography from the past and present. In regard to this, a literature review was undertaken giving emphasis on studies about city, design, history and cultural heritage. Furthermore, an engagement with the routine of Rua do Príncipe – one of the oldest streets in the downtown area – was taken earnestly resulting in records organized in the form of a notebook containing standardized interviews and photographies. Likewise, an observation form of the street allowed the investigation of its everyday life, in special case, the interaction between people and 26 properties of cultural heritage importance. Thus, it was possible to realize that the typography hardly ever correspond to the historic elements from buildings considered  cultural heritage of Joinville, being limited almost exclusively to comercial ads from the street. This way, it was possible to understand that Rua do Príncipe is a space where there are hybrid design and typographic scenarios, as well as different languages and conflicting signs. Just as many other contemporary cities, it is believed that such atmosphere is produced through the dialogue with different forms of living and, because of it, considering design and typography is an importante purpose of this work.

    Full Text Available Predicting the grain yield performance of three-way hybrids is challenging. Three-way crosses are relevant for hybrid breeding in barley ( L. and maize ( L. adapted to East Africa. The main goal of our study was to implement and evaluate genome-wide prediction approaches of the performance of three-way hybrids using data of single-cross hybrids for a scenario in which parental lines of the three-way hybrids originate from three genetically distinct subpopulations. We extended the ridge regression best linear unbiased prediction (RRBLUP and devised a genomic selection model allowing for subpopulation-specific marker effects (GSA-RRBLUP: general and subpopulation-specific additive RRBLUP. Using an empirical barley data set, we showed that applying GSA-RRBLUP tripled the prediction ability of three-way hybrids from 0.095 to 0.308 compared with RRBLUP, modeling one additive effect for all three subpopulations. The experimental findings were further substantiated with computer simulations. Our results emphasize the potential of GSA-RRBLUP to improve genome-wide hybrid prediction of three-way hybrids for scenarios of genetically diverse parental populations. Because of the advantages of the GSA-RRBLUP model in dealing with hybrids from different parental populations, it may also be a promising approach to boost the prediction ability for hybrid breeding programs based on genetically diverse heterotic groups.

  3. Potential theory

    Helms, Lester L

    2014-01-01

    Potential Theory presents a clear path from calculus to classical potential theory and beyond, with the aim of moving the reader into the area of mathematical research as quickly as possible. The subject matter is developed from first principles using only calculus. Commencing with the inverse square law for gravitational and electromagnetic forces and the divergence theorem, the author develops methods for constructing solutions of Laplace's equation on a region with prescribed values on the boundary of the region. The latter half of the book addresses more advanced material aimed at those with the background of a senior undergraduate or beginning graduate course in real analysis. Starting with solutions of the Dirichlet problem subject to mixed boundary conditions on the simplest of regions, methods of morphing such solutions onto solutions of Poisson's equation on more general regions are developed using diffeomorphisms and the Perron-Wiener-Brelot method, culminating in application to Brownian motion. In ...

  2. A Review on Recent T-way Combinatorial Testing Strategy

    2017-01-01

    Full Text Available T-way combinatorial testing aims to generate a smaller test suite size. The purpose of t-way combinatorial testing is to overcome exhaustive testing. Although many existing strategies have been developed for t-way combinatorial testing, study in this area is encouraging as it falls under NP-hard optimization problem. This paper focuses on the analysis of existing algorithms or tools for the past seven years. Taxonomy of combinatorial testing is proposed to ease the analysis. 20 algorithms or tools were analysed based on strategy approach, search technique, supported interaction and year published. 2015 was the most active year in which researchers developed t-way algorithms or tools. OTAT strategy and metaheuristic search technique are the most encouraging research areas for t-way combinatorial testing. There is a slight difference in the type of interaction support. However, uniform strength is the most utilized form of interaction from 2010 to the first quarter of 2017.

  3. Analysis to support allergen risk management: Which way to go?

    Science.gov (United States)

    Cucu, Tatiana; Jacxsens, Liesbeth; De Meulenaer, Bruno

    2013-06-19

    Food allergy represents an important food safety issue because of the potential lethal effects; the only effective treatment is the complete removal of the allergen involved from the diet. However, due to the growing complexity of food formulations and food processing, foods may be unintentionally contaminated via allergen-containing ingredients or cross-contamination. This affects not only consumers' well-being but also food producers and competent authorities involved in inspecting and auditing food companies. To address these issues, the food industry and control agencies rely on available analytical methods to quantify the amount of a particular allergic commodity in a food and thus to decide upon its safety. However, no "gold standard methods" exist for the quantitative detection of food allergens. Nowadays mostly receptor-based methods and in particular commercial kits are used in routine analysis. However, upon evaluation of their performances, commercial assays proved often to be unreliable in processed foods, attributed to the chemical changes in proteins that affect the molecular recognition with the receptor used. Unfortunately, the analytical outcome of other methods, among which are chromatographic combined with mass spectrometric techniques as well as DNA-based methods, seem to be affected in a comparable way by food processing. Several strategies can be employed to improve the quantitative analysis of allergens in foods. Nevertheless, issues related to extractability and matrix effects remain a permanent challenge. In view of the presented results, it is clear that the food industry needs to continue to make extra efforts to provide accurate labeling and to reduce the contamination with allergens to an acceptable level through the use of allergen risk management on a company level, which needs to be supported inevitably by a tailor-validated extraction and detection method.

  4. The way you say it, the way I feel it: Emotional word processing in accented speech

    Directory of Open Access Journals (Sweden)

    Anna eHatzidaki

    2015-03-01

    Full Text Available The present study examined whether processing words with affective connotations in a listener’s native language may be modulated by accented speech. To address this question, we used the Event Related Potential (ERP technique and recorded the cerebral activity of Spanish native listeners, who performed a semantic categorization task, while listening to positive, negative and neutral words produced in standard Spanish or in four foreign accents. The behavioural results yielded longer latencies for emotional than for neutral words in both native and foreign accented speech, with no difference between positive and negative words. The electrophysiological results replicated previous findings from the emotional language literature, with the amplitude of the Late Positive Complex (LPC, associated with emotional language processing, being larger (more positive for emotional than for neutral words at posterior scalp sites. Interestingly, foreign accented speech was found to interfere with the processing of positive valence and go along with a negativity bias, possibly suggesting heightened attention to negative words. The manipulation employed in the present study provides an interesting perspective on the effects of accented speech on processing affective-laden information. It shows that higher order semantic processes that involve emotion-related aspects are sensitive to a speaker’s accent.

  5. Moments Based Framework for Performance Analysis of One-Way/Two-Way CSI-Assisted AF Relaying

    KAUST Repository

    Xia, Minghua

    2012-09-01

    When analyzing system performance of conventional one-way relaying or advanced two-way relaying, these two techniques are always dealt with separately and, thus, their performance cannot be compared efficiently. Moreover, for ease of mathematical tractability, channels considered in such studies are generally assumed to be subject to Rayleigh fading or to be Nakagami-$m$ channels with integer fading parameters, which is impractical in typical urban environments. In this paper, we propose a unified moments-based framework for general performance analysis of channel-state-information (CSI) assisted amplify-and-forward (AF) relaying systems. The framework is applicable to both one-way and two-way relaying over arbitrary Nakagami-$m$ fading channels, and it includes previously reported results as special cases. Specifically, the mathematical framework is firstly developed under the umbrella of the weighted harmonic mean of two Gamma-distributed variables in conjunction with the theory of Pad\\\\\\'e approximants. Then, general expressions for the received signal-to-noise ratios of the users in one-way/two-way relaying systems and the corresponding moments, moment generation function, and cumulative density function are established. Subsequently, the mathematical framework is applied to analyze, compare, and gain insights into system performance of one-way and two-way relaying techniques, in terms of outage probability, average symbol error probability, and achievable data rate. All analytical results are corroborated by simulation results as well as previously reported results whenever available, and they are shown to be efficient tools to evaluate and compare system performance of one-way and two-way relaying.

A common procedure is to "unfold" multi-way arrays in order to obtain two-way data tables on which classical multi-block methods can be applied......-N-PLS models are easier to interpret. The hypotheses are investigated by a simulation study and two real data examples; one dealing with regression and one with classification.

    1997-03-01

    Because of the questionable applicability to extant health promotion models and middle-range theories to aboriginal peoples, foundational inquiries examining the nature of cultural beliefs and ways of knowing about health within the cultures of various ethnic groups are imperative. This article describes the ways of knowing about health reported by Ojibwe people during an ethnographic inquiry in the Great Lakes region. These ways included stories from the oral tradition, authoritative knowledge of elders, "commonsense" models of illness and health, spiritual knowledge, and knowing oneself. The health-world view, a conceptual orientation for investigating health beliefs, is offered.

    While Ising-type interactions are ideal for implementing controlled phase flip gates in one-way quantum computing, natural interactions between solid-state qubits are most often described by either the XY or the Heisenberg models. We show an efficient way of generating cluster states directly using either the imaginary SWAP (iSWAP) gate for the XY model, or the sqrt[SWAP] gate for the Heisenberg model. Our approach thus makes one-way quantum computing more feasible for solid-state devices.

  11. MUNI Ways and Structures Building Integrated Solar Membrane Project

    Energy Technology Data Exchange (ETDEWEB)

    Smith, Randall

    2014-07-03

    The initial goal of the MUNI Ways and Structures Building Integrated Solar Membrane Installation Project was for the City and County of San Francisco (CCSF) to gain experience using the integrated higher efficiency solar photovoltaic (PV) single-ply membrane product, as it differs from the conventional, low efficiency, thin-film PV products, to determine the feasibility of success of larger deployment. As several of CCSF’s municipal rooftops are constrained with respect to weight restrictions, staff of the Energy Generation Group of the San Francisco Public Utilities Commission (SFPUC) proposed to install a solar PV system using single-ply membrane The installation of the 100 kW (DC-STC) lightweight photo voltaic (PV) system at the MUNI Ways and Structures Center (700 Pennsylvania Ave., San Francisco) is a continuation of the commitment of the City and County of San Francisco (CCSF) to increase the pace of municipal solar development, and serve its municipal facilities with clean renewable energy. The fourteen (14) solar photovoltaic systems that have already been installed at CCSF municipal facilities are assisting in the reduction of fossil-fuel use, and reduction of greenhouse gases from fossil combustion. The MUNI Ways & Structures Center roof has a relatively low weight-bearing capacity (3.25 pounds per square foot) and use of traditional crystalline panels was therefore rejected. Consequently it was decided to use the best available highest efficiency Building-Integrated PV (BIPV) technology, with consideration for reliability and experience of the manufacturer which can meet the low weight-bearing capacity criteria. The original goal of the project was to provide an opportunity to monitor the results of the BIPV technology and compare these results to other City and County of San Francisco installed PV systems. The MUNI Ways and Structures Center was acquired from the Cookson Doors Company, which had run the Center for many decades. The building was

    Urban rights-of-way may be potential reservoirs of tall-grass prairie plants and butterflies. To determine if this is true, in 2007-2008, we conducted vegetation surveys of species richness and cover, and butterfly surveys of species richness and abundance, along 52 transmission lines and four remnant prairies in Winnipeg, Manitoba. We detected many prairie plants and butterflies within transmission lines. Some unmowed and infrequently managed transmission lines had native plant species richness and total percent cover of native plants comparable to that of similar-sized remnant tall-grass prairies in the region. Although we did not find significant differences in overall native butterfly numbers or species richness between rights-of-way and remnant prairies, we found lower numbers of some prairie butterflies along frequently mowed rights-of-way than within remnant tall-grass prairies. We also observed higher butterfly species richness along sites with more native plant species. By reducing mowing and spraying and reintroducing tall-grass prairie plants, urban rights-of-way could serve as extensive reservoirs for tall-grass prairie plants and butterflies in urban landscapes. Eventually, managing urban rights-of-way as reservoirs for tall-grass prairie plants and animals could contribute to the restoration of tall-grass prairie in the North American Midwest.

  5. The Aspects of Restructuring Enterprises and the Ways of Implementing the Process

    Directory of Open Access Journals (Sweden)

    Kristina Garškaitė-Milvydienė

    2014-12-01

    Full Text Available The paper discusses certain aspects of restructuring enterprises and presents different ways and measures applicable for restructuring companies; they are divided and grouped according to certain qualities. In scientific literature, measures for restructuring enterprises are most frequently classified according to organizational, legal, financial and strategic aspects. For assessing the factor of the period, passive and active ways for transforming enterprises are often singled out, where the first one is usually applied when the response to ongoing negative changes is late and actions are limited by operative anti-crisis measures targeted for cutting expenses. When the active way to the transformation of enterprises is employed, the aim of assessing the total situation of the enterprise and newly forming its strategic potential is pursued. The measures for restructuring enterprises classified with reference to different aspects differ in their goals, contents and technologies of implementation. Variety in applicable measures is predetermined by a broad range of causes and goals, and the scope of restructuring enterprises depends on the abundance of sectors to be transformed to the enterprise. Choosing a way to restructuring enterprises is also affected by external and internal environmental factors. In practice, a combination of various ways for restructuring rather than a single one of those is applied.

  6. The Sagittarius impact as an architect of spirality and outer rings in the Milky Way.

    Purcell, Chris W; Bullock, James S; Tollerud, Erik J; Rocha, Miguel; Chakrabarti, Sukanya

    2011-09-14

    Like many galaxies of its size, the Milky Way is a disk with prominent spiral arms rooted in a central bar, although our knowledge of its structure and origin is incomplete. Traditional attempts to understand our Galaxy's morphology assume that it has been unperturbed by major external forces. Here we report simulations of the response of the Milky Way to the infall of the Sagittarius dwarf galaxy (Sgr), which results in the formation of spiral arms, influences the central bar and produces a flared outer disk. Two ring-like wrappings emerge towards the Galactic anti-Centre in our model that are reminiscent of the low-latitude arcs observed in the same area of the Milky Way. Previous models have focused on Sgr itself to reproduce the dwarf's orbital history and place associated constraints on the shape of the Milky Way gravitational potential, treating the Sgr impact event as a trivial influence on the Galactic disk. Our results show that the Milky Way's morphology is not purely secular in origin and that low-mass minor mergers predicted to be common throughout the Universe probably have a similarly important role in shaping galactic structure.

These systems have nearly complete spectroscopic coverage of candidate satellites within the projected host virial radius down to {r}osatellite galaxies: 14 new satellite galaxies meet our formal criteria around our complete host systems, plus 11 additional satellites in either incompletely surveyed hosts or below our formal magnitude limit. Combined with 13 previously known satellites, there are a total of 27 satellites around 8 complete Milky-Way-analog hosts. We find a wide distribution in the number of satellites per host, from 1 to 9, in the luminosity range for which there are 5 Milky Way satellites. Standard abundance matching extrapolated from higher luminosities predicts less scatter between hosts and a steeper luminosity function slope than observed. We find that the majority of satellites (26 of 27) are star-forming. These early results indicate that the Milky Way has a different satellite population than typical in our sample, potentially changing the physical interpretation of measurements based only on the Milky Way’s satellite galaxies.

  12. Comparative analysis of one- and two-way planetary laser ranging concepts

    Laser ranging is an emerging technology for tracking interplanetary missions, offering both range accuracy and precision at the level of several millimeters. The ground segment uses existing Satellite Laser Ranging (SLR) technology, whereas the space segment requires an active system for either one- or two-way ranging. We numerically investigate the performance of one- and two-way active planetary laser ranging systems to quantify the difference in science return from missions employing this technology. In doing so, we assess the added value of the more complicated two-way system compared to its one-way counterpart. We simulate range measurement errors for both types of systems, using clock error time histories generated from Allan variance profiles. We use two test cases: a lunar polar orbiter and a Phobos lander. In the Phobos lander simulations, we include the estimation of Phobos librations and C bar 2 , 2 gravity field coefficient. For the lunar orbiter, we include an empirical force-error model in our truth model. We include the estimation of clock parameters over a variety of arc lengths for one-way range data analysis and use a variety of state arc durations for the lunar orbiter simulations. For the lunar orbiter, performance of the one- and two-way system is similar for sufficiently short clock arcs. This indicates that dynamical-model error, not clock noise, is the dominant source of estimation uncertainty. However, correlations between the clock and state parameters cause an exchange between clock and state signal for the one-way system, making these results less robust. The results for the Phobos lander show superior estimation accuracy of the two-way system. However, knowledge of Phobos' interior mass distribution from both the one- or two-way system would currently be limited to the same level by inaccuracies in our knowledge of Phobos' volume. Both the lunar orbiter and Phobos lander simulations show that the use of two-way planetary laser ranging

  13. Multi-way Communications: An Information Theoretic Perspective

    KAUST Repository

    Chaaban, Anas

    2015-09-15

    Multi-way communication is a means to significantly improve the spectral efficiency of wireless networks. For instance, in a bi-directional (or two-way) communication channel, two users can simultaneously use the transmission medium to exchange information, thus achieving up to twice the rate that would be achieved had each user transmitted separately. Multi-way communications provides an overview on the developments in this research area since it has been initiated by Shannon. The basic two-way communication channel is considered first, followed by the two-way relay channel obtained by the deployment of an additional cooperative relay node to improve the overall communication performance. This basic setup is then extended to multi-user systems. For all these setups, fundamental limits on the achievable rates are reviewed, thereby making use of a linear high-SNR deterministic channel model to provide valuable insights which are helpful when discussing the coding schemes for Gaussian channel models in detail. Several tools and communication strategies are used in the process, including (but not limited to) computation, signal-space alignment, and nested-lattice codes. Finally, extensions of multi-way communication channels to multiple antenna settings are discussed. © 2015 A. Chaaban and A. Sezgin.

  14. Three Ways of Looking at an Old Pine Tree

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Everyone knows that each thing has many different ways of being looked at. If you say something is beautiful or ugly, these are just different ways of looking at the thing. Looked at differently, you can say it is true or false; or, to view it still differently, you can say it is good or evil. It’s still the same fact, viewed in different ways, so we say the phenomenon viewed has several different viewpoints. For example, that old pine tree in the garden, whether viewed by you or me or anyone, will still be an old pine tree. Yet you see it from a positive perspective and I see it from a negative one. Your viewpoint is that of a young person, mine is that of a middle-aged person. These differences in mood and personality influence the way we see the old pine tree itself. Although the tree is a fact, the way you see it and the way I see it are two different things. If you and I both take our impressions of the tree and try to paint them or compose a poem about them, even though our respective skills may be the same, your painting or poem will have many important differences from mine. What is the reason for this? It is simply that consciousness is not totally objective and which forms one sees has many different subjective aspects.

    Antimicrobial resistance is now recognised as a threat to health worldwide. Antimicrobial stewardship aims to promote the responsible use of antibiotics and is high on international and national policy agendas. Health information technology has the potential to support antimicrobial stewardship in a number of ways, but this field is still poorly characterised and understood. Building on a recent systematic review and expert roundtable discussions, we take a lifecycle perspective of antibiotic use in hospitals and identify potential targets for health information technology-based interventions to support antimicrobial stewardship. We aim for this work to help chart a future research agenda in this critically important area.

    One-way transmission and negative refraction are the exotic wave properties founded in photonic crystals which attract a great attention due to their promising applications in photonic devices. How to integrate such two phenomena in one material or device is interesting and valuable. In this work, we theoretically and experimentally demonstrate that one-way electromagnetic space wave can be realized by means of two-dimensional magnetic photonic crystals. Simultaneously breaking the time-reversal and parity symmetries of the magnetic photonic crystals designed, we observe oblique incident space wave propagating one-way in the magnetic photonic crystals with positive or negative refraction occurring at interfaces, which can be manipulated upon the incident angle and operating frequency. Our work may offer a potential platform to realize some exotic photoelectronic and microwave devices such as one-way imaging and one-way cloaking. PMID:27387438

    Full Text Available Introduction: The Vestibular Evoked Myogenic Potential (VEMP is a promising test for the evaluation of the cholic descending vestibular system. This reflex depends of the integrity from the saccular macula, from the inferior vestibular nerve, the vestibular nuclei, the vestibule-spinal tract and effectors muscles. Objective: Perform a systematic review of the pertinent literature by means of database (COCHRANE, MEDLINE, LILACS, CAPES. Conclusion: The clinical application of the VEMP has expanded in the last years, as goal that this exam is used as complementary in the otoneurological evaluation currently used. But, methodological issues must be clarified. This way, this method when combined with the standard protocol, can provide a more widely evaluation from the vestibular system. The standardization of the methodology is fundamental criterion for the replicability and sensibility of the exam.

    Tang, Zhenghua; Lei, Dajun; Huang, Jianquan; Jin, Gui; Qiu, Feng; Yan, Wenyan

    2015-12-01

    The multiferroic Fibonacci superlattices (MFSs) are composed of single-phase multiferroic domains with polarization and magnetization according to the rule of Fibonacci sequence. We propose to construct a one-way electromagnetic waveguide by the MFSs. The forbidden band structures of the MFSs for the forward and backward electromagnetic waves are not completely overlapped, and an obvious translation between them occurs around the fixed point ω bar = 1 with broken time-reversal and space inversion symmetries (TRSIS), which indicates the existence of one-way electromagnetic modes in the MFSs. Transmission spectrum is utilized to present this property and to indicate further one-way electromagnetic modes lying within the polaritonic band gap. The maximum forbidden bandwidth (divided by midgap frequency) of 5.4% for the backward electromagnetic wave (BEW) is found, in which the forward electromagnetic wave (FEW) can pass. The functions of one-way propagation modes and polaritonic band gap integrated into the MFSs can miniaturize the one-way photonic devices. The properties can also be applied to construct compact microwave isolators.

  1. The origin of the Milky Way globular clusters

    Renaud, Florent; Agertz, Oscar; Gieles, Mark

    2017-03-01

    We present a cosmological zoom-in simulation of a Milky Way-like galaxy used to explore the formation and evolution of star clusters. We investigate in particular the origin of the bimodality observed in the colour and metallicity of globular clusters, and the environmental evolution through cosmic times in the form of tidal tensors. Our results self-consistently confirm previous findings that the blue, metal-poor clusters form in satellite galaxies that are accreted on to the Milky Way, while the red, metal-rich clusters form mostly in situ, or, to a lower extent, in massive, self-enriched galaxies merging with the Milky Way. By monitoring the tidal fields these populations experience, we find that clusters formed in situ (generally centrally concentrated) feel significantly stronger tides than the accreted ones, both in the present day, and when averaged over their entire life. Furthermore, we note that the tidal field experienced by Milky Way clusters is significantly weaker in the past than at present day, confirming that it is unlikely that a power-law cluster initial mass function like that of young massive clusters, is transformed into the observed peaked distribution in the Milky Way with relaxation-driven evaporation in a tidal field.

  2. Two-Way Finite Automata: Old and Recent Results

    Directory of Open Access Journals (Sweden)

    Giovanni Pighizzini

    2012-08-01

    Full Text Available The notion of two-way automata was introduced at the very beginning of automata theory. In 1959, Rabin and Scott and, independently, Shepherdson, proved that these models, both in the deterministic and in the nondeterministic versions, have the same power of one-way automata, namely, they characterize the class of regular languages. In 1978, Sakoda and Sipser posed the question of the cost, in the number of the states, of the simulation of one-way and two-way nondeterministic automata by two-way deterministic automata. They conjectured that these costs are exponential. In spite of all attempts to solve it, this question is still open. In the last ten years the problem of Sakoda and Sipser was widely reconsidered and many new results related to it have been obtained. In this work we discuss some of them. In particular, we focus on the restriction to the unary case and on the connections with open questions in space complexity.

    Current deep, wide field sky surveys, such as the Dark Energy Survey (DES) and Pan-STARRS, have discovered new faint satellites around the Milky Way. As these dwarf galaxies are typically very faint and among the most dark-matter dominated objects, their physical properties offer a unique opportunity to study the physics of dark matter and galaxy formation on the smallest scales. Here, I will present our Magellan/Megacam stellar photometry of three recently discovered Milky Way Satellites to have a deep observational understanding of these new objects (e.g., their star formation history, structural properties, signs of tidal disturbance). The results will be discussed in comparison to other Milky Way satellites and the classical dwarf spheroidal galaxies.

    The Dark Energy Survey (DES) offers the deepest, wide-area view of the southern sky to date, providing an unprecedented opportunity to studyfaint and/or distant stellar populations. I will describe several ongoing studies of the Milky Way environment using DES, including searches for Milky Way satellite galaxies, outer halo star clusters, stellar streams, and variable stars. In combination with an extensive spectroscopic follow-up campaign, DES has helped shed light on the missing satellites problem and the origin of the heavy elements. At the same time, the proximity of the DES footprint to the Magellanic Clouds has raised several new questions about the influence of the Milky Way's largest neighbors on the formation of the local environment. With additional imaging and improved data quality, DES promises to become an even more powerful tool to probe near-field cosmology and Galactic archeology in the years to come.

  5. Topological one-way fiber of second Chern number

    2016-01-01

    Optical fiber is a ubiquitous and indispensable component in communications, sensing, biomedicine and many other lightwave technologies and applications. Here we propose topological one-way fibers to remove two fundamental mechanisms that limit fiber performance: scattering and reflection. We design three-dimensional~(3D) photonic crystal fibers, inside which photons propagate only in one direction, that are completely immune to Rayleigh and Mie scatterings and significantly suppress the nonlinear Brillouin and Raman scatterings. A one-way fiber is also free from Fresnel reflection, naturally eliminating the needs for fiber isolators. Our finding is enabled by the recently discovered Weyl points in a double-gyroid~(DG) photonic crystal. By annihilating two Weyl points by supercell modulation in a magnetic DG, we obtain the photonic analogue of the 3D quantum Hall phase with a non-zero first Chern number~($C_1$). When the modulation becomes helixes, one-way fiber modes develop along the winding axis, with the ...

  6. Analysis of Rainfall Characteristicsfor Flood Estimation in Way Awi Watershed

    2016-03-01

    Full Text Available This study investigates rainfall intensity distribution in Way Awi watershed located in Bandar Lampung, and how their impacts on flood peak and flood hydrographs. Hourly rainfall data is examined to obtain design rainfall intensity and rainfall intensity distribution at rainfall duration from three to eight hours. Rainfall-runoff model, i.e. Rational method is used to calculate flood peak while unit hydrograph method is used to develop flood hydrograph. This study shows that in Way Awi watershed 88.3% to 96.4% of 24-hour rain occurs in three to eight hour durations. In addition, rainfall with three hour duration generates the highest flood peak, followed by four hour duration rainfall. When rainfall duration and design rainfall intensity are the same but rainfall intensity distribution is different, generated flood hydrograph may have different flood peak magnitude and timing. Result of this study is useful for flood analysis and mitigation in Way Awi watershed.

    Full Text Available In the midst of the digital revolution, we are confronted with the task of defining how media will change our lives and how we communicate with each other in the years to come. Narrative, as one of the most ancient communication tools, has undergone substantial structural changes. This paper addresses how these changes impact the way we read and write. Does the same story conveyed through different media channels signify in the same manner? In other words, what are the differences between a printed story and a digitally presented one? Have electronic reader devices altered the way stories are told and created? And how is networked communication changing the ways we tell stories?

  8. When Patients' Values Challenge Professional Integrity: Which Way Out?

    Science.gov (United States)

    Spranzi, Marta

    2016-01-01

    Patients' values and choices sometimes conflict with health-care providers' professional integrity. Increasingly, health-care teams face requests for care they deem inappropriate, particularly around decisions near the end of life. Professional standards are useful in some ways, but are insufficient from an ethical point of view. Indeed, it can be important to remember that patients' values do not necessarily lose their legitimacy when they conflict with physicians' professional integrity. By examining a paradigmatic clinical ethics consultation case, this essay explores a possible way to address situations in which doctors' integrity and patients' values clash. In order for professional integrity to play a constructive rather than adversary role in decision making, it should be understood in an inclusive way, as a combination of interconnected values in play: professional, contextual, and personal.

    Efficient requirements engineering and design is a demanding task. Design for excellence (DFX) offers a way to bring together different views and harmonizing practices. There are still impediments, for example, in having internal and external customers valued appropriately. The organizational implementation of DFX in itself is a debated question. We present a new way to organize the DFX concept in a large organization. The results are based on experiences of a large organization that operates in the area of ICT systems, and has had a successful implementation of the DFX concept for several years. Contrary to the traditional way of managing the DFX within R&D it is beneficial to organize it within also other parts of the operational subsystem, as this makes the concept and its improvement more visible and widespread in the organization. However, this requires seeing the concepts of problem domain and solution domain from a new angle.

  11. Ants can learn to forage on one-way trails.

    Directory of Open Access Journals (Sweden)

    Pedro Leite Ribeiro

    Full Text Available The trails formed by many ant species between nest and food source are two-way roads on which outgoing and returning workers meet and touch each other all along. The way to get back home, after grasping a food load, is to take the same route on which they have arrived from the nest. In many species such trails are chemically marked by pheromones providing orientation cues for the ants to find their way. Other species rely on their vision and use landmarks as cues. We have developed a method to stop foraging ants from shuttling on two-way trails. The only way to forage is to take two separate roads, as they cannot go back on their steps after arriving at the food or at the nest. The condition qualifies as a problem because all their orientation cues -- chemical, visual or any other -- are disrupted, as all of them cannot but lead the ants back to the route on which they arrived. We have found that workers of the leaf-cutting ant Atta sexdens rubropilosa can solve the problem. They could not only find the alternative way, but also used the unidirectional traffic system to forage effectively. We suggest that their ability is an evolutionary consequence of the need to deal with environmental irregularities that cannot be negotiated by means of excessively stereotyped behavior, and that it is but an example of a widespread phenomenon. We also suggest that our method can be adapted to other species, invertebrate and vertebrate, in the study of orientation, memory, perception, learning and communication.

    2012-07-01

    Full Text Available The 1991 DeWitte double one-way 1st order in v= c experiment successfully measured the anisotropy of the speed of light using clocks at each end of the RF coaxial cables. However Spavieri et al. , Physics Letters A (2012, have reported that (i clock effects caused by clock transport should be included, and (ii that this additional effect cancels the one-way light speed timing effect, implying that one-way light speed experiments “do not actually lead to the measurement of the one-way speed of light or determination of the absolute velocity of the preferred frame”. Here we explain that the Spavieri et al. derivation makes an assumption that is not always valid: that the propagation is subject to the usual Fresnel drag effect, which is not the case for RF coaxial cables. As well DeWitte did take account of the clock transport effect. The Spavieri et al. paper has prompted a clarification of these issues.

  11. Keck Spectroscopy of NGVS Sources: Milky Way Halo Star Kinematics

    Science.gov (United States)

    Zhang, Hao; Guhathakurta, Puragra; Peng, Eric W.; Toloba, Elisa; Next Generation Virgo Cluster Survey (NGVS) Collaboration

    2017-01-01

    We present a study of the kinematics of main sequence turnoff stars in the halo of the Milky Way based on Next Generation Virgo Cluster Survey photometry and Keck/DEIMOS spectroscopic follow-up. Specifically, we investigate the properties of the Virgo overdensity and Sagittarius stream Milky Way halo substructures in the foreground of the Virgo Cluster of galaxies. We use an inverse concentration (iC) parameter that characterizes the angular size of a source, which is defined by the magnitude difference measured by two different apertures for the same object. After combining this information as well as redshift measured from spectra into a Z vs iC plot, all of the objects are separated clearly into three categories: foreground Milky Way stars, Virgo globular clusters, and background galaxies. Most objects located in unexpected regions in the V_iC plot are subsequently rejected through a rigorous examination due to low spectral quality or bad imaging quality, indicating that our sample selection approach gives a very clean classification. We then select Sagittarius stream stars and Virgo overdensity stars out of the foreground star sample to characterize their distributions of spatial position, radial velocity and metallicity, from which we can probe deeper into the history of structure formation in the Milky Way Galaxy. This research was supported by NASA and the National Science Foundation. HZ has been sponsored by China Scholarship Council to carry out this research project at University of California, Santa Cruz.

  15. The Four Ways of Eco-global Criminology

    Directory of Open Access Journals (Sweden)

    Rob White

    2017-03-01

    Full Text Available In charting out the ‘four ways’ of eco-global criminology, this paper discusses the importance of recognising and acting in regards to the differences evident in (1 ways of being (ontology, (2 ways of knowing (epistemology, (3 ways of doing (methodology and (4 ways of valuing (axiology. The paper assumes and asserts that global study of environmental crime is essential to the green criminology project, and particularly an eco-global criminology approach. Specific instances of criminal and harmful activity therefore need to be analysed in the context of broad international social, political, economic and ecological processes. The article outlines the key ideas of eco-global criminology, a perspective that argues that global study must always be inclusive of voices from the periphery and margins of the world’s metropolitan centres, and critical of the social relations that sustain the epistemological as well as material realities and legacies of colonialism and imperialism. Yet, in doing so, there arise many paradoxes and conundrums that likewise warrant close attention.

    2018-01-01

    Full Text Available A dam break induced-flood propagation modeling is needed to reduce the losses of any potential dam failure. On the 25 July 2013, there was a dam break generated flood due to the failure of Way Ela Natural Dam that severely damaged houses and various public facilities. This study simulated the flooding induced by the failure of Way Ela Natural Dam. A two-dimensional (2D numerical model, HEC-RAS v.5, is used to simulate the overland flow. The dam failure itself is simulated using HECHMSv.4. The results of this study, the flood inundation, flood depth, and flood arrival time are verified by using available secondary data. These informations are very important to propose mitigation plans with respect to possible dam break in the future.

  12. A one-way shooting algorithm for transition path sampling of asymmetric barriers.

    Brotzakis, Z Faidon; Bolhuis, Peter G

    2016-10-28

    We present a novel transition path sampling shooting algorithm for the efficient sampling of complex (biomolecular) activated processes with asymmetric free energy barriers. The method employs a fictitious potential that biases the shooting point toward the transition state. The method is similar in spirit to the aimless shooting technique by Peters and Trout [J. Chem. Phys. 125, 054108 (2006)], but is targeted for use with the one-way shooting approach, which has been shown to be more effective than two-way shooting algorithms in systems dominated by diffusive dynamics. We illustrate the method on a 2D Langevin toy model, the association of two peptides and the initial step in dissociation of a β-lactoglobulin dimer. In all cases we show a significant increase in efficiency.

    2009-10-01

    We identify 10—seven for the first time—elements of cold halo substructure (ECHOS) in the volume within 17.5 kpc of the Sun in the inner halo of the Milky Way. Our result is based on the observed spatial and radial velocity distribution of metal-poor main-sequence turnoff (MPMSTO) stars in 137 Sloan Extension for Galactic Understanding and Exploration lines of sight. We point out that the observed radial velocity distribution is consistent with a smooth stellar component of the Milky Way's inner halo overall, but disagrees significantly at the radial velocities that correspond to our detections. We show that all of our detections are statistically significant and that we expect no false positives. These ECHOS represent the observable stellar debris of ancient merger events in the stellar accretion history of the Milky Way, and we use our detections and completeness estimates to infer a formal upper limit of 0.34+0.02 -0.02 on the fraction of the MPMSTO population in the inner halo that belong to ECHOS. Our detections and completeness calculations also suggest that there is a significant population of low fractional overdensity ECHOS in the inner halo, and we predict that 1/3 of the inner halo (by volume) harbors ECHOS with MPMSTO star number densities n ≈ 15 kpc-3. In addition, we estimate that there are of order 103 ECHOS in the entire inner halo. ECHOS are likely older than known surface brightness substructure, so our detections provide us with a direct measure of the accretion history of the Milky Way in a region and time interval that has yet to be fully explored. In concert with previous studies, our result suggests that the level of merger activity has been roughly constant over the past few Gyr and that there has been no accretion of single stellar systems more massive than a few percent of a Milky Way mass in that interval.

  14. A new way to proxy levels of infrastructure development

    Directory of Open Access Journals (Sweden)

    Steve Pickering

    2017-01-01

    Full Text Available Researchers in many fields have needed to develop a measure of infrastructure, and many proxies have been used toward this end, such as night light data and the Digital Chart of the World. Yet there are issues in using these methods. This paper presents a new way of proxying infrastructure: analysing the file sizes of map images on the Bing, Google, OpenStreetMap and Sina websites. The paper also demonstrates four ways in which this can be achieved. This approach is by no means perfect and does not solve all of the difficulties presented by other methods. Nevertheless, it does provide a simple and functional alternative proxy for level of infrastructure development.

  15. A two-way regularization method for MEG source reconstruction

    KAUST Repository

    Tian, Tian Siva

    2012-09-01

    The MEG inverse problem refers to the reconstruction of the neural activity of the brain from magnetoencephalography (MEG) measurements. We propose a two-way regularization (TWR) method to solve the MEG inverse problem under the assumptions that only a small number of locations in space are responsible for the measured signals (focality), and each source time course is smooth in time (smoothness). The focality and smoothness of the reconstructed signals are ensured respectively by imposing a sparsity-inducing penalty and a roughness penalty in the data fitting criterion. A two-stage algorithm is developed for fast computation, where a raw estimate of the source time course is obtained in the first stage and then refined in the second stage by the two-way regularization. The proposed method is shown to be effective on both synthetic and real-world examples. © Institute of Mathematical Statistics, 2012.

    A hunt for merging dwarf galaxies has yielded an intriguing result: 180 million light-years away, a galaxy very similar to the Milky Way with two dwarf-galaxy satellites just like our own Magellanic clouds.Unusual SatellitesThe Large and Small Magellanic clouds, as observed from Earth. [ESO/S. Brunier]The Large and Small Magellanic clouds (LMC and SMC), the only bright and star-forming satellite galaxies around the Milky Way, have proven unusual in the universe: satellite pairs of LMCSMC mass are neither common in observation nor typically produced in numerical simulations of galaxy formation and evolution.Since the probability of having such an interacting pair of satellites in a massive halo is so low, this raises questions about how our system came about. Did the Magellanic clouds form independently around the Milky Way and then interact? Were they more recently captured as an already-merging pair of dwarf galaxies? Or is there some other explanation?If we could find other systems that look like the LMCSMCMilky-Way system, we might be able to learn more about pairs of dwarf galaxies and how they interact near the halos of large galaxies like the Milky Way. Conveniently, two researchers from Yonsei University in South Korea, Sanjaya Paudel and Chandreyee Sengupta, have now identified exactly such a system.The UGC 4703 pair of dwarf galaxies show a stellar bridge connecting them a sign of their past interaction, when tidal forces stripped material from them as they passed each other. [Adapted from Paudel Sengupta 2017]An Interacting PairHunting for merging dwarf galaxies in various environments, Paudel and Sengupta found UGC 4703, an interacting pair of dwarf galaxies that are located near the isolated spiral galaxy NGC 2718.

  17. Simulation of Two-Way Pushdown Automata Revisited

    Directory of Open Access Journals (Sweden)

    Robert Glück

    2013-09-01

    Full Text Available The linear-time simulation of 2-way deterministic pushdown automata (2DPDA by the Cook and Jones constructions is revisited. Following the semantics-based approach by Jones, an interpreter is given which, when extended with random-access memory, performs a linear-time simulation of 2DPDA. The recursive interpreter works without the dump list of the original constructions, which makes Cook's insight into linear-time simulation of exponential-time automata more intuitive and the complexity argument clearer. The simulation is then extended to 2-way nondeterministic pushdown automata (2NPDA to provide for a cubic-time recognition of context-free languages. The time required to run the final construction depends on the degree of nondeterminism. The key mechanism that enables the polynomial-time simulations is the sharing of computations by memoization.

    2011-08-01

    Full Text Available Western Tibetan Buddhist movements have been described as bourgeois and puritanical in previous scholarship. In contrast, Ole Nydahl’s convert lay Karma Kagyu Buddhist movement, the Diamond Way, has drawn attention for its apparently hedonistic style. Focussing on the interpretation of Nydahl’s approach to gender and sexualities, this paper addresses the wider issues of continuity and change during the transition of Tibetan Buddhism from Asia to the West. Nydahl’s pre-modern gender stereotyping, the hetero-machismo of the Diamond Way and the mildly homophobic tone and content of Nydahl’s teaching are interpreted on the background of Indian and Tibetan Buddhist sexual ethics and traditional Tibetan cultural attitudes on sexualities. By excavating the emic genealogy of Nydahl’s teachings, the paper suggests that Nydahl’s and the Diamond Way’s view on and performance of gender and sexualities are consistent with his propagation of convert Buddhist neo-orthodoxy.

    Full Text Available The article develops new ways of creating and using interactive SVG infographics. The emphasis lies on the compatibility of SVG standard with other web standards, like XML, XSL, CSS, SMIL and ECMAScript, the advantages that it brings are particularly explored. There is a XSLT template developed which transforms XML data into SVG infographic, and the way of achieving complete control over data and data visualization is tested. This enabled the achieving of dynamic control of content and its presentation, and contributed to the results in reduced developing cost and time, better flexibility and reliability of the organizational system. The paper also studied the possibility to convey infographic message by adding interactivity, and explored technologies by means of which this can be achieved. The aspects of establishing a more efficient communication with end users, such as searchability and accessibility are also considered. SVG infographics are compared with other approaches for creating infographics in raster and vector techniques.

Its field of application is primarily in chronic diseases for the acquisition of competences in the management of treatments, in co-operation with health professionals. In ambulatory medicine, patients and health professionals are currently running up against the difficulties of the long-term follow-up with its part of uncertainty, lassitude and economic pressure. EBM and the various models of health psychology light us only partially the way. A new type of reflexive step is emerging. This way of thinking should place in its center the concept of therapeutic relation: between science and being. We summarize here our reflexive process in the course of an interdisciplinary team gathering social sciences, art and medicine.

    Observations of soft gamma rays emanating from the Milky Way from SPI/INTEGRAL reveal the annihilation of ˜2 × 1043 positrons every second in the Galactic bulge. The origin of these positrons, which annihilate to produce a prominent emission line centred at 511 keV, has remained mysterious since their discovery almost 50 yr ago. A plausible origin for the positrons is in association with the intense star formation ongoing in the Galactic centre. Moreover, there is strong evidence for a nuclear outflow in the Milky Way. We find that advective transport and subsequent annihilation of positrons in such an outflow cannot simultaneously replicate the observed morphology of positron annihilation in the Galactic bulge and satisfy the requirement that 90 per cent of positrons annihilate once the outflow has cooled to 104 K.

    One-way quantum computing allows any quantum algorithm to be implemented easily using just measurements. The difficult part is creating the universal resource, a cluster state, on which the measurements are made. We propose a scalable method that uses a single, multimode optical parametric oscillator (OPO). The method is very efficient and generates a continuous-variable cluster state, universal for quantum computation, with quantum information encoded in the quadratures of the optical frequency comb of the OPO.

  1. Goals, ways and the roots of our economic crisis

    Directory of Open Access Journals (Sweden)

    Bob Goudzwaard

    2014-08-01

    Full Text Available This article deals with the question if and how far religious points of view and messages of churches involved matter in the analysis of the roots of the present global economic crisis, and even more in the discussion about how to overcome the crisis itself. Economic experts such as Stiglitz point to the presence of factors such as greed, fear and utmost selfish behaviour. It inevitably leads to the ethical, but in fact also the religious question of how far people, especially economic agents, can go in the pursuit of their own economic interests without doing harm to others. Jesus asked his disciples to follow him: with Bonhoeffer, we could call that a Way-orientation. Where and how far can a conflict therefore arise between human goal-orientations, on the one hand, and a biblical Way-orientation, on the other hand? And is it indeed relevant when considering our present economic crisis? This article defends the last position, describing some categories (such as the choice of ultimate meaning, the sacro-sanctity of chosen instruments, and the demonisation of opponents which indicate that the borderline has been passed between responsible and irresponsible goal-orientations. The glorification of greed and the delegation of ultimate power to financial markets indicate that at this moment elements of idolatry (or the obedience to Mammon are at hand. They are also aggravating the present economic crisis. This implies that returning to the choice for decisive normative Way-orientations in economic life is possibly the only true way out of the present economic crisis.

  5. On the rotation curve of our Milky Way

    Science.gov (United States)

    Shi, Weibin; Ruan, Guiping

    We precent a new rotation curve of our Milky Way through fitting from velocity measurements of HII regions, CO, HI, in clouds and, complexes, classical Cepheid, planetary nebulae, asymptotic giant branch stars and open star clusters. For each class of objects we adopted same selection criteria. First, we renalyze the galactic rotation curve using each class of object with the form Θ/Θ0 = a1 (R/R0 )a2 + a3 (Brand & Blitz 1993). We find cluster and AGB stars have big deviations. And we compare the rotation curve of each object to find AGB stars are not good at fitting rotation curve. So we use other kinds of objects to fit the rotation curve. Then, we compare the rotation curve of quadrant I, II and quadrant III, IV to find the effect of the spiral arms, the streaming motion and mass asymmetry in the Milky Way . Last, we use the choosen data to obtain a rotation curve with a mass distribution model of the Galaxy; there are three components in this model: the spheroid, the disk and the halo (Paczynski 1990). the mass of the Milky Way which we obtain from the model is agreement with the latest values in the literature. The new Galactic constants R0 = 8.0 kpc, and Θ0 = 220.0 km s-1 were adopted in our work.

  6. Milky Way a Swifter Spinner, More Massive, New Measurements Show

    Fasten your seat belts -- we're faster, heavier, and more likely to collide than we thought. Astronomers making high-precision measurements of the Milky Way say our home Galaxy is rotating about 100,000 miles per hour faster than previously understood. That increase in speed, said Mark Reid, of the Harvard-Smithsonian Center for Astrophysics, increases the Milky Way's mass by 50 percent, bringing it even with the Andromeda Galaxy. "No longer will we think of the Milky Way as the little sister of the Andromeda Galaxy in our Local Group family." Milky Way Artist's Conception of our Milky Way Galaxy: Blue, green dots indicate distance measurements. CREDIT: Robert Hurt, IPAC; Mark Reid, CfA, NRAO/AUI/NSF JPEG graphic with scale marks on sides PostScript graphic with scale marks on sides The larger mass, in turn, means a greater gravitational pull that increases the likelihood of collisions with the Andromeda galaxy or smaller nearby galaxies. Our Solar System is about 28,000 light-years from the Milky Way's center. At that distance, the new observations indicate, we're moving at about 600,000 miles per hour in our Galactic orbit, up from the previous estimate of 500,000 miles per hour. The scientists are using the National Science Foundation's Very Long Baseline Array (VLBA) radio telescope to remake the map of the Milky Way. Taking advantage of the VLBA's unparalleled ability to make extremely detailed images, the team is conducting a long-term program to measure distances and motions in our Galaxy. They reported their results at the American Astronomical Society's meeting in Long Beach, California. The scientists observed regions of prolific star formation across the Galaxy. In areas within these regions, gas molecules are strengthening naturally-occuring radio emission in the same way that lasers strengthen light beams. These areas, called cosmic masers, serve as bright landmarks for the sharp radio vision of the VLBA. By observing these regions repeatedly at times

    Full Text Available We use the most up-to-date Milky Way model and solar orbit data in order to test the hypothesis that the Sun's galactic spiral arm crossings cause mass extinction events on Earth. To do this, we created a new model of the Milky Way's spiral arms by combining a large quantity of data from several surveys. We then combined this model with a recently derived solution for the solar orbit to determine the timing of the Sun's historical passages through the Galaxy's spiral arms. Our new model was designed with a symmetrical appearance, with the major alteration being the addition of a spur at the far side of the Galaxy. A correlation was found between the times at which the Sun crosses the spiral arms and six known mass extinction events. Furthermore, we identify five additional historical mass extinction events that might be explained by the motion of the Sun around our Galaxy. These five additional significant drops in marine genera that we find include significant reductions in diversity at 415, 322, 300, 145 and 33 Myr ago. Our simulations indicate that the Sun has spent ~60% of its time passing through our Galaxy's various spiral arms. Also, we briefly discuss and combine previous work on the Galactic Habitable Zone with the new Milky Way model.

    The accelerated process of urbanization that is shifting the aspects of Brazilian cities - most clearly in South East and South region states - is inherently involved with decayed levels of quality of life and little or any concern at all with the sustainability of such urban expansion. Besides the social difficulties generated from this non-planned growth - mainly in the cities' outskirts - there are many questions related to urbanization that should be reconsidered such as water, soil and air pollution; lack of water resources; floods, insufficient public transport and traffic problems; urban infra-structure and lodging privations and inadequate soil installment. This paper aims at showing how this disordered urban growth plays an important role on PETROBRAS' pipeline right of way located at the great cities urban areas, more specifically the Urban Right Of Way that cross the metropolitan region of the city of Sao Paulo. Also, it is an objective to express how such urbanization propitiate the execution of basic infra-structure in a way of integrating habitation, sanitation, environment and geotechnical sectors with the purposes of PETROBRAS of maintaining as priority the integrity of the pipelines located on the ROW as well as the integrity of these ROW themselves.

    Full Text Available This research paper proposes an analytical approach to the study of the phenomenon of the film-induced pilgrimage tourism, along one of the most historical and relevant European cultural route: the Way of St. James or Camino de Santiago.In the present study, and in order to point out the relation between film broadcast and film-induced tourism, we combine the review of the Jacobean cinema with the statistical analysis of the pilgrims arrived to Santiago de Compostela during the last decade. So, our main aim is to analyse the repercussion of the Jacobean Cinema in the attractiveness of the Way of St. James as tourism destination. We take into consideration the role of the film producers and we also ponder on the marketing policies of the Autonomous Community, which are aimed at promoting the pilgrim’s routes, the Cathedral and the city of Santiago de Compostela. The cinema has played a less important role until now, in comparison with the impact of travel guides and the Jacobean literature, but it is increasing its impact in the international tourism markets. Recently, the American film The Way can be considered to be the first promoter of the film-induced tourism, because the arrivals of pilgrims from USA have been increased after the broadcast of this film since 2010.

    One-way acoustic transmission is achieved through a brass plate with a periodic grating on the surface. Using the Schlieren imaging technique, the positive and negative propagation processes of acoustic waves through the periodic structure were experimentally observed. Simulations were performed using the finite-element method. Both the experimental and simulation results revealed a very large transmission ratio between positive and negative incidence, thus demonstrating the feasibility of using this structure as an acoustic rectifier. The results indicate that the structure has a broadband working frequency. The structure has potential applications in ultrasonic medical devices and sonochemical reactors.

  17. Ways to Increase Launch Velocities of 2-Stage Gas Guns

    The amount of space debris is rapidly increasing and the debris is distributed over a wide variety of orbits. Satellites, manned space vehicles and space stations will have to pay increasing attention to the dangers of impacts with space debris. Various armoring techniques (i.e., double or triple layer armor) will have to tested extensively to determine the most effective armor per unit weight. Intersecting near-earth orbits can lead to impact velocities up to 15 km/sec. Conventional two-stage light gas guns can launch intact, controlled-shape projectiles with a density of 1.2 gm/cc and length- to-diameter ratios of 0.5-1.0 at velocities up to 8-9 km/sec. Higher velocities (10-11 km/sec) can be obtained' for very light projectiles. The higher launch velocities tend to be very severe on the high pressure coupling and barrel of the gun and lead to short component lifetimes. Clearly, the ability to raise the launch velocity of a gun (for reasonably massive projectile shapes) from 8-9 km/sec to 11-13 km/sec (or higher), without reduction of component lifetimes, would have significant benefits. This would allow much better simulation of the higher velocity debris impacts as well as better simulation of high speed re-entry into planetary atmospheres. Several techniques for increasing the launcher muzzle velocity above 8-9 km/sec have been studied using CFD simulations and appear to offer the potential for significant gains. The first technique is to use multiple compressions, instead of a single compression, in the pump tube of the light gas gun. In a sense, this is a kind of pre-heating of the gas in the pump tube; other types of pre-heating have yielded disappointing results in the past. The dynamics of the multiple compression pump tube is very different, however, from the earlier techniques, where the pump tube was typically heated ohmically before the gun 2 cycle was started. In this paper, we present CFD calculations that show that significant increases in muzzle

    Before using a organic material for biogas production it is essential to evaluate the methane production potential. The methane potential is one important tool possible to use during planning of new plants but also when new materials are considered for already running biogas plants. The chemical composition of different organic material varies extensively and this will have an impact on both the degradability and the methane potential. Information about the methane potential of a specific material can sometimes be found in the literature or can be calculated after a chemical/ physical or biological characterization. Here, the BMP test (Biochemical Methane Potential) is a commonly used method. Today the BMP test is a commonly used method to determine the methane potential. Many national and international research groups, consultants as well as personal at biogas plants are using this method and there is a lot of data available in the literature from such tests. In addition there are several protocols giving guidelines on how to execute a BMP-test. The BMP-test is performed in many different ways, not always under optimized conditions, and there is a lack of information on how to interpret the obtained data. This report summarizes knowledge from the literature and the experience from a Swedish referee group, consisting of persons being active performers of BMP-tests. The report does not include a standardized protocol as the procedure can be performed in different ways depending on available equipment and on the type of material to be tested. Instead the report discusses different factors of great importance for a successful test giving reliable results. The report also summarizes important information concerning the interpretation and how to present results in order to allow comparison of data from different test.

  19. Mapping Milky Way Halo Structure with Blue Horizontal Branch Stars

    2017-01-01

    The use of blue horizontal brach (BHB) and red giant branch stars as tracers of stellar debris streams is a common practice and has been useful in the confirmation of kinematic properties of previously identified streams. This work explores less common ways of untangling the velocity signatures of streams traveling radially to our line of sight, and to peer toward the higher density region of the Galactic Center using data from the Sloan Digital Sky Survey (SDSS). Using spectra of BHB stars, we are able to kinematically distinguish moving groups in the Milky Way halo. The results of this thesis advance our knowledge of the following stellar halo substructures: the Pisces Stellar Stream, the Hercules-Aquila Cloud, the Hercules Halo Stream, and the Hermus Stream. A study of red giant stars led to the kinematic discovery of the Pisces Stellar Stream. Red giant stars were also examined to determine that the previously identified velocity signature that was suggested for the Hercules-Aquila Cloud was due to disk star contamination and errors in preliminary SDSS velocities. The Hercules Halo Stream is a previously unidentified structure that could be related to the Hercules-Aquila Cloud, and was discovered as a velocity excess of SDSS BHB stars. We identify a group of 10 stars with similar velocities that are spatially coincident with the Hermus Stream. An orbit is fit to the Hermus Stream that rules out a connection with the Phoenix Stream.This work was supported by NSF grants AST 09-37523, 14-09421, 16-15688, the NASA/NY Space Grant fellowship, and contributions made by The Marvin Clan, Babette Josephs, Manit Limlamai, and the 2015 Crowd Funding Campaign to Support Milky Way Research.

  20. Swarm intelligence. A whole new way to think about business.

    2001-05-01

    What do ants and bees have to do with business? A great deal, it turns out. Individually, social insects are only minimally intelligent, and their work together is largely self-organized and unsupervised. Yet collectively they're capable of finding highly efficient solutions to difficult problems and can adapt automatically to changing environments. Over the past 20 years, the authors and other researchers have developed rigorous mathematical models to describe this phenomenon, which has been dubbed "swarm intelligence," and they are now applying them to business. Their research has already helped several companies develop more efficient ways to schedule factory equipment, divide tasks among workers, organize people, and even plot strategy. Emulating the way ants find the shortest path to a new food supply, for example, has led researchers at Hewlett-Packard to develop software programs that can find the most efficient way to route phone traffic over a telecommunications network. South-west Airlines has used a similar model to efficiently route cargo. To allocate labor, honeybees appear to follow one simple but powerful rule--they seem to specialize in a particular activity unless they perceive an important need to perform another function. Using that model, researchers at Northwestern University have devised a system for painting trucks that can automatically adapt to changing conditions. In the future, the authors speculate, a company might structure its entire business using the principles of swarm intelligence. The result, they believe, would be the ultimate self-organizing enterprise--one that could adapt quickly and instinctively to fast-changing markets.

    Control of the electromagnetic waves in nano-scale structured materials is crucial to the development of next generation photonic circuits and devices. In this context, hyperbolic metamaterials, where elliptical isofrequency surfaces are morphed into surfaces with exotic hyperbolic topologies when the structure parameters are tuned, have shown unprecedented control over light propagation and interaction. Here we show that such topological transitions can be even more unusual when the hyperbolic metamaterial is endowed with nonreciprocity. Judicious design of metamaterials with reduced spatial symmetries, together with the breaking of time-reversal symmetry through magnetization, is shown to result in nonreciprocal dispersion and one-way topological phase transitions in hyperbolic metamaterials.

    Nanos is an essential factor of germ line success in all animals tested. This gene encodes a Zn-finger RNA-binding protein that in complex with its partner pumilio, binds to and changes the fate of several known transcripts. We summarize here the documented functions of nanos in several key organisms, and then emphasize echinoderms as a working model for how nanos expression is regulated. Nanos presence outside of the target cells is often detrimental to the animal, and in sea urchins, nanos expression appears to be regulated at every step of transcription, and post-transcriptional activity, making this gene product exciting, every which way.

    Black holes are real astrophysical objects, but their interiors are hidden and can only be "observed" through mathematics. The structure of rotating black holes is typically illustrated with the help of special coordinates. But any such coordinate choice necessarily results in a distorted view, just as the choice of projection distorts a map of the Earth. The truest way to depict the properties of a black hole is through quantities that are coordinate-invariant. We compute and plot all the independent curvature invariants of rotating, charged black holes for the first time, revealing a landscape that is much more beautiful and complex than usually thought.

    Astronomy is full of beautiful skyscapes, shining stars and huge planets. The vast majority of them can be transformed into tactile images and complemented by audio descriptions. These translations of visual information into raised lines, shapes and textures can be felt with the fingertips instead of viewed with the eyes. In this way, the beauties of the Universe enter the universe of blind and visually impaired people. Happily, we all have radio broadcasting as an important source of information and entertainment. Science radio programmes can bring the real music of the spheres (as Pythagoras once suggested) to the audience.

    The Milky Way provides an ideal opportunity to study baryon flows in the circumgalactic medium of a star-forming spiral galaxy. High velocity clouds (HVCs) seen in UV absorption toward background AGN probe the multi-phase ionized gas in the Galactic CGM. In this talk new observations from the Cosmic Origins Spectrograph (COS) on Hubble will be presented, focusing on two Galactic regions: the biconical outflow from the Galactic Center, which drives gas into the Fermi Bubbles, and the Smith Cloud, an accreting HVC close to the Galactic disk showing clear signs of fragmentation. These observations allow us to constrain the rates of gas circulation in the Galactic halo.

    Like other spiral galaxies, the Milky Way drives a biconical nuclear wind. Outflowing gas is visible in enhanced emission across the electromagnetic spectrum, including the Fermi gamma-ray bubbles and radio lobes extending above and below the Galactic Center. Last year we presented the first results from a Hubble Space Telescope program to detect and characterize the nuclear wind using UV absorption-line spectroscopy of background AGN. Here we extend those results using several other sight lines in the northern Fermi Bubble region, allowing us to reconstruct, for the first time, the wind velocity profile, and constrain the physical mechanism driving the outflow.

    2012-02-01

    Full Text Available Accretion of fresh gas at a rate of ∼ 1M☉yr−1 is necessary in star-forming disc galaxies, such as the Milky Way, in order to sustain their star-formation rates. In this work we present the results of a new hydrodynamic simulation supporting the scenario in which the gas required for star formation is drawn from the hot corona that surrounds the star-forming disc. In particular, the cooling of this hot gas and its accretion on to the disc are caused by the passage of cold galactic fountain clouds through the corona.

  1. Nudge: a new and better way to improve health?

    Vallgårda, Signild

    2012-02-01

    Nudging, or libertarian paternalism, is presented as a new and ethically justified way of improving people's health. It has proved influential and is currently taken up by the governments in the US, the UK and France. One may question the claim that the approach is new, in any case it has many similarities with the idea of "making healthy choices easier". Whether the approach is better from an ethical perspective depends on the ethical principles one holds. From a paternalistic perspective there could be no objections, but from a libertarian, there are several. Contrary to what the authors state, libertarian paternalism is an oxymoron.

  2. A Planetary Geophysicist Does EPO: Lessons Learned Along the Way

    2011-12-01

    My "day job" is numerical modeling of the interiors of the terrestrial planets, but I have also done EPO projects for the last 17 years while at the Lunar and Planetary Institute. These range from single, hour long talks in classrooms or astronomy clubs, to week-long summer workshops for teachers and librarians, and even semester-long programs, along with a number of curriculum development projects. EPO projects are a great way to help develop both the next generation of scientists and, more importantly, of scientifically literate citizens and taxpayers. Here are a few lessons learned along the way in the school of hard knocks. (1) An engaging delivery style is even more important in EPO presentations than it is in college lectures or conference presentations. Emphasize a few key concepts rather than numerous facts, and keep the jargon out. Good analogies can go a long way towards explaining a concept to any age group. I teach the role of size in planetary cooling by first asking students how long it takes to cook food of various sizes (a hamburger, roast beef, turkey). (2) If you will be working with a group of students for more than one class period, classroom friendly activities strengthen the learning process. Such activities do not need to be elaborate - when teaching about the Moon, I sometimes assign students to take their parents outside at night and show them how to find lava flows on the Moon. Teachers usually need to have classroom activities that are aligned to state or national teaching standards. Fortunately, many effective, standards-aligned activities already exist, so you don't need to reinvent the wheel. For a useful listing of planetary science and astronomy activities, see the LPI website www.lpi.usra.edu/education/resources/ (3) Although EPO work can be personally rewarding, it is not always well rewarded in a professional context, and it can be difficult to find the time and financial resources to sustain major projects. We sometimes use a

    In micro four-point probe measurements, three-way flexible L-shaped cantilever probes show significant advantages over conventional straight cantilever probes. The L-shaped cantilever allows static contact to the sample surface which reduces the frictional wear of the cantilever tips. We analyze...... the geometrical design space that must be fulfilled for the cantilevers to obtain static contact with the test sample. The design space relates the spring constant tensor of the cantilevers to the minimal value of the static tip-to-sample friction coefficient. Using an approximate model, we provide the analytical...

    Food insecurity is a serious public health issue for Aboriginal people (First Nations [FN], Métis, and Inuit) living in Canada. Food security challenges faced by FN people are unique, especially for those living in remote and isolated communities. Conceptualizations of food insecurity by FN people are poorly understood. The purpose of this study was to explore the perceptions of food insecurity by FN adults living in a remote, on-reserve community in northern Ontario known to have a high prevalence of moderate to severe food insecurity. A trained community research assistant conducted semi-directed interviews, and one adult from each household in the community was invited to participate. Questions addressed traditional food, coping strategies, and suggestions to improve community food security and were informed by the literature and a community advisory committee. Thematic data analyses were carried out and followed an inductive, data-driven approach. Fifty-one individuals participated, representing 67% of eligible households. The thematic analysis revealed that food sharing, especially with family, was regarded as one of the most significant ways to adapt to food shortages. The majority of participants reported consuming traditional food (wild meats) and suggested that hunting, preserving and storing traditional food has remained very important. However, numerous barriers to traditional food acquisition were mentioned. Other coping strategies included dietary change, rationing and changing food purchasing patterns. In order to improve access to healthy foods, improving income and food affordability, building community capacity and engagement, and community-level initiatives were suggested. Findings point to the continued importance of traditional food acquisition and food sharing, as well as community solutions for food systems change. These data highlight that traditional and store-bought food are both part of the strategies and solutions participants suggested

    We consider the most general non-Hermitian Hulthen potential to study the scattering of spin-less relativistic particles. The conditions for CC, SS and CPA are obtained analytically for this potential. We show that almost total absorption occurs for entire range of incidence energy for certain parameter ranges of the potential and hence term this as ‘black potential’. Time reversed of the same potential shows perfect emission for the entire range of particle energy. We also present the classical analog of this potential in terms of waveguide cross section. - Highlights: • Relativistic scattering properties of a spin zero particle due to most general non-Hermitian Hulthen potential are discussed. • Analytical conditions for CC, CPA and SS are obtained. • Broadband CPA is obtained for entire range of incidence energy. • Non-Hermitian Hulthen potential is parametrized in such a way to show broadband CPA and/or CC. • Waveguide analog of such potential is presented.

  14. Dynamics of stellar and HI streams in the Milky Way halo

    Full Text Available Stellar streams are key players in many aspects of Milky Way studies and, in particular, studying their orbital dynamics is crucial for furthering our understanding of the Milky Wayʼs gravitational potential. Although this is not a trivial task when faced with incomplete dynamical phase-space information, transverse motions of streams can nevertheless be comprehended by harnessing the information contained within their radial velocity gradients. Such methods are not only applicable to stellar streams, but also to HI streams residing in the Milky Way halo. Here, I present the results of two studies that use radial velocity gradients to determine the systemʼs orbit: for Hercules, one of the ‘ultra-faint’ dwarf galaxies exhibiting a large ellipticity and located at a distance of 140 kpc, showing that it may in fact be a stellar stream, and for a string of high-velocity HI clouds belonging to the GCN complex, indicating its likelihood for being a gaseous stream at a distance of approximately 20 kpc.

  15. Culicoides Species Communities Associated with Wild Ruminant Ecosystems in Spain: Tracking the Way to Determine Potential Bridge Vectors for Arboviruses.

    Directory of Open Access Journals (Sweden)

    Sandra Talavera

    Full Text Available The genus Culicoides Latreille 1809 is a well-known vector for protozoa, filarial worms and, above all, numerous viruses. The Bluetongue virus (BTV and the recently emerged Schmallenberg virus (SBV are responsible for important infectious, non-contagious, insect-borne viral diseases found in domestic ruminants and transmitted by Culicoides spp. Both of these diseases have been detected in wild ruminants, but their role as reservoirs during the vector-free season still remains relatively unknown. In fact, we tend to ignore the possibility of wild ruminants acting as a source of disease (BTV, SBV and permitting its reintroduction to domestic ruminants during the following vector season. In this context, a knowledge of the composition of the Culicoides species communities that inhabit areas where there are wild ruminants is of major importance as the presence of a vector species is a prerequisite for disease transmission. In this study, samplings were conducted in areas inhabited by different wild ruminant species; samples were taken in both 2009 and 2010, on a monthly basis, during the peak season for midge activity (in summer and autumn. A total of 102,693 specimens of 40 different species of the genus Culicoides were trapped; these included major BTV and SBV vector species. The most abundant vector species were C. imicola and species of the Obsoletus group, which represented 15% and 11% of total numbers of specimens, respectively. At the local scale, the presence of major BTV and SBV vector species in areas with wild ruminants coincided with that of the nearest sentinel farms included in the Spanish Bluetongue Entomological Surveillance Programme, although their relative abundance varied. The data suggest that such species do not exhibit strong host specificity towards either domestic or wild ruminants and that they could consequently play a prominent role as bridge vectors for different pathogens between both types of ruminants. This finding would support the hypothesis that wild ruminants could act as reservoirs for such pathogens, and subsequently be involved in the reintroduction of disease to livestock on neighbouring farms.

    2009-07-01

    Some F1 hybrid plants between three species of the Aegilops genus and different hexaploid wheat Triticum aestivum cultivars show certain self-fertility, with averages of F{sub 1} hybrids bearing F{sub 2} seeds of 8.17%, 5.12% and 48.14% for Aegilops biuncialis, Aegilops geniculata and Aegilops triuncialis respectively. In the Ae. triuncialis-wheat combination with Astral wheat cultivar, the fertility was higher than that found in the other combinations. All the F2 seeds studied were spontaneous amphiploids (2n=10x=70). The present study evidences the possibility of spontaneous formation of amphiploids between these three Aegilops species and hexaploid wheat and discusses their relevance for gene transference. Future risk assessment of transgenic wheat cultivars needs to evaluate the importance of amphiploids as a bridge for transgene introgression and for gene escape to the wild. (Author)

    2016-10-01

    Full Text Available Renal cell carcinoma (RCC is the most common neoplasm that occurs in the kidney and is marked by a unique biology, with a long history of poor response to conventional cancer treatments. In the past few years, there have been significant advancements to understand the biology of RCC. This has led to the introduction of novel targeted therapies in the management of patients with metastatic disease. Patients treated with targeted therapies for RCC had shown positive impact on overall survival, however, no cure is possible and patients need to undergo treatment for long periods of time, which raises challenges to manage the associated adverse events. Moreover, many patients may not respond to it and even response may not last long enough in the responders. Many inhibitors of the Mammalian target of Rapamycin (mTOR signaling pathway are currently being used in treatment of advanced RCC. Studies showed that inhibitions of mTOR pathways induce Mitogen-Activated Protein Kinase (MAPK escape cell death and cells become resistant to mTOR inhibitors. Because of this, there is a need to inhibit both pathways with their inhibitors comparatively for a better outcome and treatment of patients with RCC.

  18. Altering the way the optic nerve head responds to intraocular pressure-a potential approach to glaucoma therapy.

    Science.gov (United States)

    Strouthidis, Nicholas G; Girard, Michael J A

    2013-02-01

    Over the past decade, engineering principles have been used to explain why a mechanical load, intraocular pressure, can lead to the development of glaucomatous optic neuropathy. This has led to the 'biomechanical theory' of glaucoma, which posits that the behavior of optic nerve head connective tissues (specifically within the peripapillary sclera and lamina cribrosa) in response to intraocular pressure (regardless of its magnitude) can directly and indirectly influence the physiology and pathophysiology of the optic nerve head. Given that the biomechanics of the sclera and lamina cribrosa probably influence retinal ganglion cell loss in glaucoma, the idea that altering biomechanical behavior might be protective against glaucoma is an appealing notion. There is some evidence to suggest that stiffening the peripapillary sclera may be protective against the development of glaucoma in an animal model. It is technically possible to stiffen the sclera in vivo using collagen cross-linking techniques already applied in vivo to the cornea in the treatment of keratoconus. It has yet to be established whether scleral cross-linking is safe in humans and that it confers anything more than a theoretical advantage in terms of reducing the risk of glaucomatous damage.

    Full Text Available In recent decades, information technology in healthcare, such as Electronic Medical Record (EMR system, is potential to improve service quality and cost efficiency of the hospital. The continuous use of EMR systems has generated a great amount of data. However, hospitals tend to use these data to report their operational efficiency rather than to understand their patients. Base on a dataset of inpatients’ medical records from a Chinese general public hospital, this study applies a configuration analysis from a managerial perspective and explains inpatients management in a different way. Four inpatient configurations (valued patients, managed patients, normal patients, and potential patients are identified by the measure of the length of stay and the total hospital cost. The implications of the finding are discussed.

  20. Hormones and breast cancer: can we use them in ways that could reduce the risk?

    Directory of Open Access Journals (Sweden)

    Khalid Mahmud

    2011-12-01

    Full Text Available Many hormones promote or inhibit breast cancer in different ways. These effects and the mechanisms involved are reviewed in order to suggest a potentially safer use of hormones. Natural estrogens, administered transdermally, and natural progesterone may be the safest combination of female hormones. Increased intake of cruciferous vegetables could provide additional safety by improving 2-hydoxyestrone and diminishing 16 alphahydroxyestrone. Testosterone and dehydroepiandrosterone (DHEA may directly inhibit breast cancer, but could potentially stimulate it by being aromatized into estrogen in the breast. Modest doses with blood level monitoring appear logical. Melatonin and oxytocin are inhibitory to breast and other cancers. Insulin is a growth factor for breast cancer. Managing insulin resistance before the onset of diabetes could reduce the risk. Tri-iodothyronine (T3 has multiple anti-breast cancer effects. Synthroid may not increase T3 levels adequately. Human growth hormone does not appear to increase risk; but it should not be given for performance enhancement.
