  4. Stabilization of Néel order in frustrated magnets with increasing magnetic field

    2013-01-01

    Full Text Available For low-dimensional frustrated quantum magnets, the dependence of the staggered moment ms on a magnetic field is nonmonotonic: For small and intermediate fields, quantum fluctuations are gradually suppressed, leading to an increase of ms (H. For large applied magnetic fields however, the classically expected monotonous decrease is recovered. For the same reasons, the Néel ordering temperature TN of such compounds first increases and then exhibits a reentrant behavior as a function of the field strength. The quantitative analysis of this behavior is an excellent tool to determine the frustration parameter of a given compound. We have derived a general linear spin-wave (LSW theory in the presence of a magnetic field. Based on our LSW theory, including a small interlayer coupling, we use a self-consistent approach determining TN by the condition of a vanishing total moment. We apply our findings to the recently measured field dependence of the magnetic ordering temperature TN of Cu(pz2 (ClO42 in the framework of the S = 1/2 two-dimensional J1-J2 Heisenberg model. The observed increase with increasing field strength can be understood naturally using an intermediate frustration ratio J2/J1 ≈ 0.2, which is in accordance with the field dependence of the staggered moment.

    2016-01-01

    This work was focused on studying the properties of the electromagnetic calorimeter for the Future Circular Collider (FCC) [1]. FCC is an accelerator that will possibly be built in the 2040s-2050s. Its circumference would be 100 km with the center of mass energy ps=100TeV in proton-proton collisions. Detectors used to record FCC collisions will consist of the tracker, cryostat, electromagnetic calorimeter (EMCal), hadronic calorimeter (HCal) and muon chambers. In this work, we shall study the EMCal and its properties. One of the properties of the environment that this particular detector will have to face is the presence of a strong magnetic eld in the volume of the calorimeter. Studies carried out in this work are preliminary studies focused on addressing the eects that the magnetic eld will have on the electromagnetic shower evolution.

    2013-01-01

    Contrary to neutral markers, the major histocompatibility complex (MHC) can reflect the fitness and adaptive potential of a given species due to its association with the immune system. For this reason, the use of MHC in endangered wildlife management has increased greatly in recent years. Here, we isolated complementary DNA (cDNA) and genomic DNA (gDNA) sequences to characterize the MHC class II β genes in Hainan Eld's deer (Cervus eldi hainanus), a highly endangered cervid, which recovered from a severe population bottleneck consisting of 26 animals. Analysis of 7 individuals revealed the presence of 3 DRB and 3 DQB putatively functional gDNA sequences. The Ceel-DRB and DQB sequences displayed high variability in exon 2, and most nonsynonymous substitutions were detected in this region. Phylogenetic analysis indicated that trans-species evolution of MHC class II β might occur in the Cervinae subfamily. Comparison of the number of sequences between gDNA and cDNA revealed that all sequences isolated from the genome were detectable in the cDNA libraries derived from different tissues (including the liver, kidney, and spleen), suggesting none of these sequences were derived from silent genes or pseudogenes. Characterization of the MHC class II β genes may lay the foundation for future studies on genetic structure, mate choice, and viability analysis in Hainan Eld's deer.

    Pierron F.

    2010-06-01

    Full Text Available The paper presents an experimental application of a method leading to the identification of the elastic and damping material properties of isotropic vibrating plates. The theory assumes that the searched parameters can be extracted from curvature and deflection fields measured on the whole surface of the plate at two particular instants of the vibrating motion. The experimental application consists in an original excitation fixture, a particular adaptation of an optical full-field measurement technique, a data preprocessing giving the curvature and deflection fields and finally in the identification process using the Virtual Fields Method (VFM. The principle of the deflectometry technique used for the measurements is presented. First results of identification on an acrylic plate are presented and compared to reference values. Details about a new experimental arrangement, currently in progress, is presented. It uses a high speed digital camera to over sample the full-field measurements.

  14. Russian spiritual tradition through the conception of «The Confessionalization field»

    Directory of Open Access Journals (Sweden)

    Khondzinskii Pavel, archpriest

    2015-04-01

    Full Text Available Confessionalization theory appeared in the second half of the twentieth century to describe the history of the German Protestantism in XVI-XVII centuries. The theory infers the gradual isolation of the denomination religiously, culturally, socially and politically. Later, this same theory was used to describe the same process in the catholic countries. Today, the scientific community is actively discussing the possibility of an «orthodox» confessionalization. Further to this discussion, the author tries to clarify this theory. Firstly, if the straight and narrow sense the process of «confessionalization» (especially in the sense of «a new symbiosis between church and state institutions» is a particular modern history process and the product of modernization, then in a broader sense, in the sense of a strong commitment to the breeding of the traditions (not at all possible levels, but only on the mental or cultural, this process can be extended to other periods, and other denominations. Secondly, the very need of confessionalization (no matter how consistent is its realization, arises only in the common cultural fi eld where the borders should be raised. The need for this is confessionalization. The above mentioned theory is presented in this article on the example of the Russian Church tradition. Particularly, the confessionalization concept can explain the emergence of theological and philosophical ideas introduced by the fi rst Slavophiles.

    Older people represent the majority of cancer patients but their specific needs are often ignored in the development of health-related quality of life (HRQOL) instruments. The European Organisation for Research and Treatment of Cancer (EORTC) QLQ-ELD15 was developed to supplement the EORTC's core questionnaire, the QLQ-C30, for measuring HRQOL in patients aged >70 years in oncology studies. Patients (n=518) from 10 countries completed the QLQ-C30, QLQ-ELD15 and a debriefing interview. Eighty two clinically stable patients repeated the questionnaires 1 week later (test-retest analysis) and 107 others, with an expected change in clinical status, repeated the questionnaires 3 months later (response to change analysis, RCA). Information from the debriefing interview, factor analysis and item response theory analysis resulted in the removal of one item (QLQ-ELD15QLQ-ELD14) and revision of the proposed scale structure to five scales (mobility, worries about others, future worries, maintaining purpose and illness burden) and two single items (joint stiffness and family support). Convergent validity was good. In known-group comparisons, the QLQ-ELD14 differentiated between patients with different disease stage, treatment intention, number of comorbidities, performance status and geriatric screening scores. Test-retest and RCA analyses were equivocal. The QLQ-ELD14 is a validated HRQOL questionnaire for cancer patients aged 70 years. Changes in elderly patients' self-reported HRQOL may be related to both cancer evolution and non-clinical events.

    Full Text Available Biostimulants are compounds that infl uence physiological processes in plants, producing better growth and enhancing stress tolerance. The effect of some biostimulants on vines was investigated over a number of years to assess their effect both on the incidence of esca leaf symptoms in the vineyard and on the growth of Phaeomoniella chlamydospora artifi cially inoculated into potted vines. Field trials were carried out for 4–7 years in fi ve 15-20-yearold vineyards infected with esca proper. Potted plants were sprayed with biostimulants, after which the vine trunks were inoculated with P. chlamydospora, and then the vines were sprayed again with biostimulants in the following 2 or 3 growing seasons. On the whole, biostimulants in the fi eld did not reduce foliar symptoms. The percentage of symptomatic vines that had shown symptoms in previous years was higher in the biostimulant-sprayed plots. In the greenhouse, a certain reduction of internal necrosis caused by P. chlamydospora was seen with three of the four biostimulants tested. Prospects for biostimulants as a means control esca are discussed.

  1. MEMS-based contact stress field measurements at a rough elastomeric layer: local test of Amontons’ friction law in static and steady sliding regimes

    Directory of Open Access Journals (Sweden)

    Debrégeas G.

    2010-06-01

    Full Text Available We present the results of recent friction experiments in which a MEMS-based sensing device is used to measure both the normal and tangential stress fields at the base of a rough elastomer film in frictional contact with smooth, rigid, glass indentors. We consider successively multicontacts under (i static normal loading by a spherical indentor and (ii frictional steady sliding conditions against a cylindrical indentor, for an increasing normal load. In both cases, the measured fields are compared to elastic calculations assuming (i a smooth interface and (ii Amontons’ friction law. In the static case, significant deviations are observed which decrease with increasing load and which vanish when a lubricant is used. In the steady sliding case, Amontons’ law reproduces rather satisfactorily the experiments provided that the normal/tangential coupling at the contact interface is taken into account. We discuss the origin of the difference between the Amontons fields and the measured ones, in particular the effect of the finite normal and tangential compliances of the multicontact interface.

    Depression in older adults is common and is associated with poor quality of life, increased morbidity and early mortality, and increased health and social care use. Collaborative care, a low-intensity intervention for depression that is shown to be effective in working-age adults, has not yet been evaluated in older people with depression who are managed in UK primary care. The CollAborative care for Screen-Positive EldeRs (CASPER) plus trial fills the evidence gap identified by the most recent guidelines on depression management. To establish the clinical effectiveness and cost-effectiveness of collaborative care for older adults with major depressive disorder in primary care. A pragmatic, multicentred, two-arm, parallel, individually randomised controlled trial with embedded qualitative study. Participants were automatically randomised by computer, by the York Trials Unit Randomisation Service, on a 1 : 1 basis using simple unstratified randomisation after informed consent and baseline measures were collected. Blinding was not possible. Sixty-nine general practices in the north of England. A total of 485 participants aged ≥ 65 years with major depressive disorder. A low-intensity intervention of collaborative care, including behavioural activation, delivered by a case manager for an average of six sessions over 7-8 weeks, alongside usual general practitioner (GP) care. The control arm received only usual GP care. The primary outcome measure was Patient Health Questionnaire-9 items score at 4 months post randomisation. Secondary outcome measures included depression severity and caseness at 12 and 18 months, the EuroQol-5 Dimensions, Short Form questionnaire-12 items, Patient Health Questionnaire-15 items, Generalised Anxiety Disorder-7 items, Connor-Davidson Resilience Scale-2 items, a medication questionnaire, objective data and adverse events.

    Full Text Available The Democratic Republic of Congo (DRC is the country in the world which reported the highest number of cholera cases to WHO from 2002 to 2007 (128 936 cases out of a worldwide 902 071 cases. We, therefore, implemented research work which intends to understand the epidemiology of cholera in the DRC and to ensure improvements in the strategy to fight against cholera. This broad study enabled us to accurately determine the cholera epidemic’s mechanisms on different scales; to identify the source zones of the disease, and the groups of populations acting as vectors of the spread. It was then possible to demonstrate the role of “sanctuary”, played by some suburbs of lakeside cities. A collaborative network, including several scientific institutions in Europe and in the DRC, local and national government administrations in the field of public health and sanitation, international agencies, NGOs and private foundations, was progressively set up. Following the conclusions of our epidemiological studies, a drastic change of strategy was proposed: the limited curative approach on the one hand, the few existing water/sanitation programs on the other hand, have been merged in a global approach involving a larger scale water and sanitation infrastructure improvement, environmental protection, hygiene awareness and medical surveys targeting a few focus areas playing a central role in the epidemics. In conclusion, by better targeting intervention zones, one can gather human and technical resources previously scattered on the vast territory of the DRC. The strategy presented here revives the hope to eliminate cholera in the DRC.La République Démocratique du Congo (RDC est le pays qui a déclaré le plus grand nombre de cas de choléra à l’OMS entre 2002 et 2007 (128 936 cas sur un nombre total de 902 071 de cas dans le monde.

    Full Text Available Social isolation is defined as the process of people losing their contacts with other social resources or their willingness to participate. Social isolation is a grave and widespread problem among seniors in society causing many harmful health conditions. Social isolation may be prevented by defining risk factors in seniors and leading them to suitable resources. The elderly should be encouraged to share their experiences and continue to produce for as long as possible, so that they are prevented from feeling isolated from society and the continuity of their economic productivity is ensured.

  10. Characterization of axially-symmetric magnetic elds

    CERN Document Server

    AUTHOR|(CDS)2087237; Buzio, Marco

    In solenoids for particle accelerators, the magnetic field is usually mapped by means of 3D Hall-sensing systems through a burdensome and costly procedure. A further problem arises from a coherent treatment between the beam physics requirements, the qualification of numerical models, the design and manufacturing of the magnet, and the magnetic measurements. For example, when the magnet is misaligned with respect to the longitudinal direction of the mapper, the fringe field shows spurious components. A method was therefore developed for measuring the magnetic field of axisymmetric magnets by exploiting their inherent symmetry. The method yields a measurement of the magnetic flux linked with a pair of sensing coils as a function of their longitudinal position. An induction transducer, sensitive to the longitudinal and radial components of the solenoid under test, has been designed and constructed. A transport system moves the transducer along the magnet axis, covering the full length of the magnet and including...

    A new method capable of capturing coherent electric field structures propagating at nearly the speed of light in plasma with a time resolution as small as a few femtoseconds is proposed. This method uses a few femtoseconds long relativistic electron bunch to probe the wake produced in a plasma by an intense laser pulse or an ultra-short relativistic charged particle beam. As the probe bunch traverses the wake, its momentum is modulated by the electric field of the wake, leading to a density variation of the probe after free-space propagation. This variation of probe density produces a snapshot of the wake that can directly give many useful information of the wake structure and its evolution. Furthermore, this snapshot allows detailed mapping of the longitudinal and transverse components of the wakefield. We develop a theoretical model for field reconstruction and verify it using 3-dimensional particle-in-cell (PIC) simulations. This model can accurately reconstruct the wakefield structure in the linear regime...

    The Carlitz rank of a permutation polynomial f over a finite field Fq is a simple concept that was introduced in the last decade. Classifying permutations over Fq with respect to their Carlitz ranks has some advantages, for instance f with a given Carlitz rank can be approximated by a rational...... linear transformation. In this note we present our recent results on the permutation behaviour of polynomials f+g, where f is a permutation over Fq of a given Carlitz rank, and g ∈ Fq[x] is of prescribed degree. We describe the relation of this problem to the well-known Chowla-Zassenhaus conjecture. We...

    Full Text Available The objective of this study is to know the biobgical effects of  electromagnetic field treatment on four successive generations of mice. Fourty eight male and female mice of Swiss Webster Strain, 3 months of old, and 35 - 40 g body weight, were kept in a controlled environment and fed a standard diet. Mice were divided into 6 groups of four couples each. The first group was exposed to electromagnetic field of I kV/10 cm, the second group to 2 kV/10 cm, and the third group to 3 kV/10 cm. The remaining 3 groups were served as untreated controls of the first, second, and third group, respectively. Each couple of mice was placed in a cage (26x20x11 cm with wire metal cage tops. The cages of experimental groups with mice inside, were then put on the negative terminal plate of a pair of parallel aluminium plate electrodes. These cages were  perpendicular to the positive electrode plate at a distance of I0 cm. Subsequently, the electrodes were connected to stepup transformer as an alternating current power supply. All mice belonging to experimental and untreated control groups were allowed to mate, gastate, and deliver the first up to fourth generations, During investigation, all generations of experimental groups were continuously treated to electromagnetic field, while generations of untreated control groups received no treatment to electromagnetic field, During the study, all mice were housed in a room having a temperature of 26ᵒ C and a light - dark cycle of 12:12 hours. The results of this study showed that exposure of mice to electromagnitic field results in reduced fertility with no change in sex ratio of the offspring. Exposure to electromagnetic field, however, were effective in inducing congenital anomalies, such as micropthalmy, white eyes, short hind legs, dwarf mice, and tumors in both sexes of the offspring which caused of death after 3 - 4 months of old. A large mortality rate were found, especially in the third and fourth generations. No congenital anomalies and tumors were noted in untreated controls. ln conclusion, we suggest that several facts which found in this study were the result of changes in genetic material of the sperm or eggs during spermatogenesis or oogenesis, respectively, i.e. a mutagenic effect. This interaction between electromagnetic field and the living cell, may then cause biological effects on cells, tissues, and organs, so that finally there are consequences for the whole organisms.

    Wall, Ellis L; Hartley, Matt

    2017-05-01

    The endangered Burmese brow antlered deer (Rucervus eldii thamin) is a medium sized tropical cervid kept in a number of European zoos. Studbook data and anecdotal reports have suggested that this species suffers from poor reproductive success and relatively high neonatal mortality in captivity. Questionnaires were sent to 10 European zoos, holding 91 (20.71.0) deer, in order to record information on husbandry practices and enclosure design. Studbook analysis was performed to determine reproductive success and mortality values at each of the zoos participating in the study. Statistical analysis was carried out to identify any links between husbandry or enclosure design and the population parameters calculated from the studbook. From the nine zoos that were analyzed in this study, no significant differences were found for population parameters between male and female deer. Neonatal mortality was negatively correlated to enclosure size (in males) and enclosure cover (in females). Positive correlations were found between enclosure cover, average temperature and group size with life expectancy, and negative correlations between enclosure visibility and visitor distance with female life expectancy. These results may be useful for informing husbandry guidelines, although further research into stress responses in captivity is recommended for this species to improve their welfare. © 2017 Wiley Periodicals, Inc.

    2014-11-19

    Depression accounts for the greatest disease burden of all mental health disorders, contributes heavily to healthcare costs, and by 2020 is set to become the second largest cause of global disability. Although 10% to 16% of people aged 65 years and over are likely to experience depressive symptoms, the condition is under-diagnosed and often inadequately treated in primary care. Later-life depression is associated with chronic illness and disability, cognitive impairment and social isolation. With a progressively ageing population it becomes increasingly important to refine strategies to identity and manage depression in older people. Currently, management may be limited to the prescription of antidepressants where there may be poor concordance; older people may lack awareness of psychosocial interventions and general practitioners may neglect to offer this treatment option. CASPER Plus is a multi-centre, randomised controlled trial of a collaborative care intervention for individuals aged 65 years and over experiencing moderate to severe depression. Selected practices in the North of England identify potentially eligible patients and invite them to participate in the study. A diagnostic interview is carried out and participants with major depressive disorder are randomised to either collaborative care or usual care. The recruitment target is 450 participants. The intervention, behavioural activation and medication management in a collaborative care framework, has been adapted to meet the complex needs of older people. It is delivered over eight to 10 weekly sessions by a case manager liaising with general practitioners. The trial aims to evaluate the clinical and cost effectiveness of collaborative care in addition to usual GP care versus usual GP care alone. The primary clinical outcome, depression severity, will be measured with the Patient Health Questionnaire-9 (PHQ-9) at baseline, 4, 12 and 18 months. Cost effectiveness analysis will assess health-related quality of life using the SF-12 and EQ-5D and will examine cost-consequences of collaborative care. A qualitative process evaluation will be undertaken to explore acceptability, gauge the extent to which the intervention is implemented and to explore sustainability beyond the clinical trial. Results will add to existing evidence and a positive outcome may lead to the commissioning of this model of service in primary care. ISRCTN45842879 (24 July 2012).

    Full Text Available Günümüz ekonomik koşulları ve enerji kaynaklarının büyük bir hızla tükenmekte olması, mevcut enerji kaynaklarının en verimli şekilde kullanılmasını zorunlu hale getirmiştir. Bu nedenle otomotiv endüstrisinde yakıt tüketimini azaltmak üzere değişik yük ve hız şartlarında motorlardan talep edilen gücün çevreyi en az kirleterek ve mümkün olan en ekonomik şekilde alınabilmesine yönelik yapılan çalışmalar artan hızla devam etmektedir. Teknolojinin gelişimine paralel olarak gerçekleştirilen bu çalışmalar sayesinde motorların tasarım ve işletme parametreleri değişik çalışma şartlarına göre optimize edilerek yakıtın en verimli şekilde kullanılmasına çalışılmaktadır. Motorun çalışma şartlarına göre sıkıştırma oranının değiştirilmesine yönelik yapılan çalışmalarla olumlu sonuçlar elde edilmiştir. Kısmi yüklerde yanma veriminin, yakıt ekonomisinin ve emisyonların iyileştirilmesi için sıkıştırma oranının artırılması, motorun yüksek yük ve düşük hız koşullarında ise olası vuruntu ve sert çalışmayı önlemek için sıkıştırma oranının bir miktar azaltılması gerekmektedir. Bu çalışmada, buji ile ateşlemeli değişken sıkıştırma oranlı motorlar konusunda yapılan araştırmalar, yakıt ekonomisi, motor çıkış gücü ve termik verim açısından incelenmiştir. Kısmi ve orta yük şartlarında değişken sıkıştırma oranlı motorlarla yapılan deney sonuçlarına göre motor gücünün arttığı, özgül yakıt tüketiminin azaldığı, yakıt ekonomisinde özellikle kısmi yüklerde %30'a varan iyileşmeler elde edildiği ve ayrıca bazı egzoz emisyon değerlerinde ciddi azalmalar sağlandığı tespit edilmiştir.

    Efforts to reduce the burden of illness and personal suffering associated with depression in older adults have focused on those with more severe depressive syndromes. Less attention has been paid to those with mild disorders/subthreshold depression, but these patients also suffer significant impairments in their quality of life and level of functioning. There is currently no clear evidence-based guidance regarding treatment for this patient group. To establish the clinical effectiveness and cost-effectiveness of a low-intensity intervention of collaborative care for primary care older adults who screened positive for subthreshold depression. A pragmatic, multicentred, two-arm, parallel, individually randomised controlled trial with a qualitative study embedded within the pilot. Randomisation occurred after informed consent and baseline measures were collected. Thirty-two general practitioner (GP) practices in the north of England. A total of 705 participants aged ≥ 75 years during the pilot phase and ≥ 65 years during the main trial with subthreshold depression. Participants in the intervention group received a low-intensity intervention of collaborative care, which included behavioural activation delivered by a case manager for an average of six sessions over 7-8 weeks, alongside usual GP care. Control-arm participants received only usual GP care. The primary outcome measure was a self-reported measure of depression severity, the Patient Health Questionnaire-9 items PHQ-9 score at 4 months post randomisation. Secondary outcome measures included the European Quality of Life-5 Dimensions, Short Form questionnaire-12 items, Patient Health Questionnaire-15 items, Generalised Anxiety Disorder seven-item scale, Connor-Davidson Resilience Scale two-item version, a medication questionnaire and objective data. Participants were followed up for 12 months. In total, 705 participants were randomised (collaborative care n = 344, usual care n = 361), with 586 participants (83%; collaborative care 76%, usual care 90%) followed up at 4 months and 519 participants (74%; collaborative care 68%, usual care 79%) followed up at 12 months. Attrition was markedly greater in the collaborative care arm. Model estimates at the primary end point of 4 months revealed a statistically significant effect in favour of collaborative care compared with usual care [mean difference 1.31 score points, 95% confidence interval (CI) 0.67 to 1.95 score points; p managing multimorbidities in people with subthreshold depression.

    Full Text Available Abstract Background Depression accounts for the greatest burden of disease among all mental health problems, and is expected to become the second-highest amongst all general health problems by 2020. By the age of 75, 1 in 7 older people meet formal diagnostic criteria for depression. Efforts to ameliorate the burden of illness and personal suffering associated with depression in older people have focussed on those with more severe depressive syndromes. Less attention has been paid to those with mild disorders/sub-threshold depressive syndromes but these patients also suffer impairments in their quality of life and level of functioning. Methods/Design The CASPER study has been designed to assemble an epidemiological cohort of people over 75 years of age (the CASPER cohort, from which we will identify those eligible to participate in a trial of collaborative care for sub-threshold depression (the CASPER trial. We aim to undertake a pragmatic randomised controlled multi-centre trial evaluating the effectiveness and cost-effectiveness of collaborative care; a low intensity psychological intervention in addition to usual general practitioner care versus usual general practitioner care alone. General practitioners from practices based in the North of England will be asked to identify potentially eligible patients over the age of 75 years. Patients will be sent a letter inviting them to participate in the study. We aim to recruit approximately 540 participants for the CASPER trial. A diagnostic interview will be carried out to ascertain trial eligibility with the major depressive episode module of the Mini International Neuropsychiatric Interview (M.I.N.I., eligible participants randomised to either the intervention or usual care. The primary outcome will be measured with the Patient Health Questionnaire-9 (PHQ-9 and additional quality of life measures will be collected. Data will be collected at baseline, 4 and 12 months for both trial and cohort participants. Trial Registration ISRCTN: ISRCTN02202951

    A study carried out by Mutadis and CEPN, on request of the CEA, aimed at supplying some elements allowing to elaborate some performance criteria for a long-term management system in front of situations of temporary abandonment of radioactive waste disposal facilities. The first part of the study has been the identification of case studies illustrating situations of loss of maintenance or temporary abandonment. The second phase has been the selection and analysis of 4 case studies (the ancient underground cavities in Ile-de-France, the regulation relative to new underground quarries, the abandoned mines in Loraine basin, and Unesco's approach for the protection of mankind world patrimony). These cases have been analysed with respect to various aspects: actors involved, construction management and memory preservation, liabilities in time and space, prevention means, scheduling, and resumption strategies. The concepts of abandonment, scheduling and resumption have been precised and analysed in a third part according to the case studies. Three goals - avoiding abandonment, encouraging scheduling and resumption - and eight characteristics are drawn from this analysis, which are indicators of the robustness of the system implemented to fulfill these 3 goals. These characteristics appear as strongly interdependent. (J.S.)

    Full Text Available Soybean is the most important crop in Argentina and Rachiplusia nu (Gueneé (Lepidoptera: Noctuidae is one of its main pests. In this study, the toxicity of five pyrethroids applied topically and by exposure to films on filter paper was evaluated on third instar larvae from a laboratory strain and a field population of R. nu. Four cyanopyrethroids and one non-cyanopyrethroid (permethrin were tested. All cyanopyrethroids showed the same order of increasing toxicity, regardless of the form of application and origin of the larvae: cypermethrin La soja es el cultivo más importante en la República Argentina y Rachiplusia nu (Gueneé (Lepidoptera: Noctuidae, una de sus principales plagas. En este estudio se evaluó la toxicidad de cuatro cianopiretroides y un no-cianopiretroide, aplicados en forma tópica o por exposición a filmes sobre papeles de filtro, en ninfas del tercer estadio de una cepa de laboratorio y una población de campo de R. nu. Todos los cianopiretroides mostraron el mismo orden de toxicidad creciente, independientemente de la forma de aplicación y del origen de las larvas: cipermetrina < ?-cihalotrina < deltametrina < ß-ciflutrina. Los valores de Dosis de Volteo para el 50% (DV50 y de Tiempo de Volteo para el 50% (TV50 aumentaron en función de la solubilidad de los cianopiretroides en agua. El no-cianopiretroide permetrina mostró un comportamiento diferente: fue el insecticida más tóxico para la cepa de laboratorio cuando se hizo una aplicación tópica, pero el menos tóxico cuando las larvas fueron expuestas a filmes sobre papeles de filtro. En general, todos los piretroides fueron más tóxicos para las larvas criadas en laboratorio que para las provenientes del campo. La estimación de los valores de Factor de Resistencia (FR permitió establecer que la población de campo presentaba resistencia moderada o baja a permetrina, cipermetrina y ?-cihalotrina, cuando los insecticidas fueron aplicados en forma tópica. Sin embargo, no se detectó resistencia cuando se realizó la exposición en papeles de filtro tratados. No hubo correlación entre los valores de FR obtenidos por ambos métodos. Estos resultados sugieren que la población de campo de R. nu estudiada, presentaba resistencia moderada a algunos piretroides, y que la aplicación tópica es un método más apropiado que la exposición a filmes sobre papeles de filtro para cuantificar la resistencia.

    2016-11-01

    Early language delay (ELD) is one of the earliest indicators of autism spectrum disorder (ASD), and predicts later cognitive and behavioral outcomes. We aimed to determine the neural correlates of ELD in autism, and examine the relationships between gray matter (GM), age of first word/phrase, and core ASD symptoms. We used voxel-based morphometry to examine whole-brain differences in GM in 8-13 year old children with autism (n = 13 ELD; n = 22 non-ELD) and 35 age-matched typically developing (TD) children. Multiple regression analyses examined the relationships between GM, age of first word/phrase, and autism diagnostic observation schedule (ADOS) scores. Composite age of first word/phrase negatively correlated with GM throughout the cerebellum. Both ASD groups (ELD and non-ELD) had reduced GM in right cerebellar Crus I/II when compared to TD children. Left cerebellar Crus I/II was the only region in the brain that differentiated ELD and non-ELD children, with ELD children showing reduced GM relative to both non-ELD and TD groups. Group×score interactions converged in left Crus I/II, such that the non-ELD group showed poorer ADOS scores with increasing GM, whereas the ELD group showed poorer ADOS scores as GM decreased. Reduced GM in right cerebellar Crus I/I was related ASD diagnosis, while children with ELD showed additional reduced GM in left Crus I/II. These findings highlight the importance of specific cerebellar networks in both ASD and early language development, and suggest that bilateral disruption in cerebellar regions that interconnect with fronto-parietal networks could impact language acquisition in ASD.

  19. The Origin and Structure of the Magnetic Fields and Currents of AGN Jets

    Directory of Open Access Journals (Sweden)

    Denise Gabuzda

    2017-02-01

    Full Text Available This paper reviews observational evidence obtained to date about the overall structure of the magnetic fields in the jets of Active Galactic Nuclei (AGN. Because they are sensitive to the line-of-sight magnetic-field component, Faraday rotation observations of AGN jets provide an effective tool for searching for toroidal jet magnetic fields, whose line-of-sight component changes systematically across the jet. Transverse Faraday rotation measure (RM gradients providing direct evidence for helical/toroidal magnetic fields have been reliably detected in nearly 40 AGN on parsec scales. Helical magnetic fields are believed to form due to the combined action of the rotation of the central black hole and accretion disk, and these observations demonstrate that at least some of this helical field survives to distances well beyond the Very Long Baseline Interferometry (VLBI core. Observations of reversals in the direction of the transverse RM gradients in a number of AGN provide evidence for a“return”magnetic field forming a nested helical-field structure with oppositely directed azimuthal components in the inner and outer regions of the helical magnetic field. The collected data now provide firm evidence for a predominance of inward jet currents on parsec scales and outward currents on scales greater than a few tens of parsecs. This suggests a global pattern of magnetic fields and currents with an inward current near the jet axis and an outward current farther from the jet axis, with these currents closing in the accretion disk and far out in the radio lobes, forming a self-consistent set of fields and currents together with the implied nested helical-field structure.

    The randomized phase III ELOQUENT-2 study (NCT01239797) evaluated the efficacy and safety of elotuzumab + lenalidomide/dexamethasone (ELd) versus lenalidomide/dexamethasone (Ld) in relapsed/refractory multiple myeloma. ELd reduced the risk of disease progression/death by 30% versus Ld (hazard ratio [HR] 0·70). Median time from diagnosis was 3·5 years. We present extended 3-year follow-up data. Endpoints included progression-free survival (PFS), overall response rate (ORR) and interim overall survival (OS). Exploratory post-hoc analyses included impact of time from diagnosis and prior lines of therapy on PFS, and serum M-protein dynamic modelling. ORR was 79% (ELd) and 66% (Ld) (P = 0·0002). ELd reduced the risk of disease progression/death by 27% versus Ld (HR 0·73; P = 0·0014). Interim OS demonstrated a trend in favour of ELd (P = 0·0257); 1-, 2- and 3-year rates with ELd versus Ld were: 91% versus 83%, 73% versus 69% and 60% versus 53%. In patients with ≥ median time from diagnosis and one prior therapy, ELd resulted in a 53% reduction in the risk of progression/death versus Ld (HR 0·47). Serum M-protein dynamic modelling showed slower tumour regrowth with ELd. Adverse events were comparable between arms. ELd provided a durable and clinically relevant improvement in efficacy, with minimal incremental toxicity. © 2017 John Wiley & Sons Ltd.

    The extended line defect (ELD) mimicking grain boundaries in two-dimensional systems is theoretically investigated in BN, GaN, and AlN semiconductor materials with a single layer honeycomb structure. The ELD consists of octagonal-square membered rings. Density functional calculations of the electronic density of states, scanning tunneling microscopy and transmission electron microscopy image simulations are analyzed. Our results revealed that the ELDs are stable in all considered monolayers. In addition, electronic density of states calculations demonstrated that in gap states are emerged when ELD is incorporated into the honeycomb structures. Finally, results on armchair nanoribbons with bare-edges and hydrogenated edges are discussed.

    To investigate nursing staff attitudes towards involvement and role in end-of-life decisions (ELDs) and the relationships with sociodemographic and work-related characteristics. Survey study among nationally representative Dutch research sample consisting of care professionals. Nursing staff working in hospitals, home care, nursing homes or homes for the elderly were sent ELD-questionnaire. 66% (n=587). Most respondents had been involved in ELD. Three quarters wanted to be involved in whole ELD process; 58% agreed that decisions to withhold/withdraw treatment ought to be discussed with the nurses involved; 64% believed patients would talk rather to nurses than physicians; 72% thought physicians are usually prepared to listen to nurses' opinions. Hospital and highly educated nursing staff indicated relatively more often that they want to be involved in ELD. Majority of nursing staff want to be involved in ELD. Work setting and educational level are determining factors in attitudes of nursing staff regarding involvement in ELD. Awareness on the important role nurses have and want to have in ELD should be raised, and taken into account in trainings on end-of-life care for nurses and physicians and development of guidelines for communication about ELD between patients, nursing staff and physicians.

    Energy Technology Data Exchange (ETDEWEB)

    Betti, Riccardo [Univ. of Rochester, NY (United States)

    2016-01-11

    The magnetized spherical implosion campaign funded by this grant is summarized in this progress report. The main goal of this grant was to improve the seed eld generator MIFEDS (Magneto- Inertial Fusion Energy Delivery System) on the OMEGA laser to enable experiments at high elds (> 8 T) and to carry out magnetized spherical implosion experiments to study the e ect of magnetic elds on the fusion yield. New experiments were carried out in the last budget period to study the e ect of higher elds and shaped laser pulses. These new experiments improved the magnetized implosion database and allowed us to improve the con dence of our conclusions with respect to the e ect of magnetic elds on implosion performance. The main conclusion is that adding magnetic eld leads to a 30% higher neutron yield, but using seed magnetic eld higher than 8 T does not further increase the neutron yield. A further conclusion is that the yield enhancement due to the magnetic eld is approximately independent of the laser pulse shape.

  6. Higgs-Like Particle due to Revised Quantum Electrodynamics

    Directory of Open Access Journals (Sweden)

    Lehnert B.

    2013-07-01

    Full Text Available A Higgs-like particle having zero net electric charge, zero spin, and a nonzero rest mass can be deduced from an earlier elaborated revised quantum electrodynamical theory which is based on linear symmetry breaking through a nonzero electric field divergence in the vacuum state. This special particle is obtained from a composite longitudinal solution based on a zero magnetic field strength and on a nonzero divergence but a vanishing curl of the electric field strength. The present theory further differs from that of the nonlinear spontaneously broken symmetry by Higgs, in which elementary particles obtain their masses through an interaction with the Higgs field. An experimental proof of the basic features of a Higgs-like particle thus supports the present theory, but does not for certain confirm the process which would generate massive particles through a Higgs field

    2013-12-01

    End-of-life decisions (ELDs) represent a controversial subject, with ethical dilemmas and empirical ambiguities that stand at the intersection of ethics and medicine. In a non-Western population, we examined individual differences in perceiving ELDs that end the life of a patient as acceptable and found that an attitude toward euthanasia (ATE) scale consists of 2 factors representing voluntary and nonvoluntary euthanasia. Also, acceptance of ELDs that end the life of a patient negatively correlated with life satisfaction, honesty-humility, conscientiousness, and intrinsic and extrinsic personal motivation toward religion. These findings provided additional construct validity of the ATE scale.

    We explore the role played by the di eomorphism group and its unitary representations in relativistic quantum eld theory. From the quantum kinematics of particles described by representations of the di eomorphism group of a space-like surface in an inertial reference frame, we reconstruct the local relativistic neutral scalar eld in the Fock representation. An explicit expression for the free Hamiltonian is obtained in terms of the Lie algebra generators (mass and momentum densities). We suggest that this approach can be generalized to elds whose quanta are spatially extended objects.

    2008-12-01

    We investigated the recognition of pairs of faces (same or different facial identities and expressions) in two groups of 14 children aged 6-10 years, with either an expressive language disorder (ELD), or a mixed language disorder (MLD), and two groups of 14 matched healthy controls. When looking at their global performances, children with either expressive (ELD) or MLD have few differences from controls in either face or emotional recognition. At contrary, we found that children with MLD, but not those with ELD, take identical faces to be different if their expressions change. Since children with mixed language disorders are socially more impaired than children with ELD, we think that these features may partly underpin the social difficulties of these children.

    2012-02-01

    Belgium legalized euthanasia in 2002. Physicians must report each euthanasia case to the Federal Control and Evaluation Committee. This study examines which end-of-life decisions (ELDs) Belgian physicians label 'euthanasia', which ELDs they think should be reported and the physician characteristics associated with correct labelling of euthanasia cases, the awareness that they should be reported and the reporting of them. Five hypothetical cases of ELDs: intensified pain alleviation, palliative/terminal sedation, euthanasia with neuromuscular relaxants, euthanasia with morphine and life-ending without patient request were presented in a cross-sectional survey of 914 physicians in Belgium in 2009. About 19% of physicians did not label a euthanasia case with neuromuscular relaxants 'euthanasia', 27% did not know that it should be reported. Most physicians labelled a euthanasia case with morphine 'intensification of pain and symptom treatment' (39%) or 'palliative/terminal sedation' (37%); 21% of physicians labelled this case 'euthanasia'. Cases describing other ELDs were sometimes also labelled 'euthanasia'. Factors associated with a higher likelihood of labelling a euthanasia case correctly were: living in Flanders, being informed about the euthanasia law and having a positive attitude towards societal control over euthanasia. Whether a physician correctly labelled the euthanasia cases strongly determined their reporting knowledge and intentions. There is no consensus among physicians about the labelling of euthanasia and other ELDs, and about which cases must be reported. Mislabelling of ELDs could impede societal control over euthanasia. The provision of better information to physicians appears to be necessary.

    2015-01-01

    The use of REBCO coated conductors is envisaged for many applications, extending from power cables to high-field magnets. Whatever the case, thermal properties of REBCO tapes play a key role for the stability of superconducting devices. In this work, we present the first study on the longitudinal thermal conductivity (k) of REBCO coated conductors in magnetic fields up to 19 T applied both parallelly and perpendicularly to the thermal-current direction. Copper-stabilized tapes from six industrial manufacturers have been investigated. We show that zero-field k of coated conductors can be calculated with an accuracy of ‡ 15% from the residual resistivity ratio of the stabilizer and the Cu/non-Cu ratio. Measurements performed at high fields have allowed us to evaluate the consistency of the procedures generally used for estimating in-field k in the framework of the Wiedemann-Franz law from an electrical characterization of the materials. In-field data are intended to provide primary ingredients for the ...

    Diabetes mellitus is known to adversely affect the bones and be associated with increased fracture risk. We examined whether eldecalcitol (ELD), an active vitamin D 3 derivative, could inhibit the diabetic bone loss in streptozotocin-induced type I diabetic rats. ELD (10, 20, or 40 ng/kg), alfacalcidol (ALF; 25, 50, or 100 ng/kg), or vehicle was administered 5 times per week for 12 weeks from 1 week after diabetes induction. Normal control rats received the vehicle. Bone turnover markers, bone mineral density (BMD), and biomechanical strength of the lumbar spine and femur were measured, and bone histomorphometry was performed. Content of advanced glycation end products (AGEs) in the femoral shaft was also determined. In diabetic rats, serum osteocalcin (OC) concentration was lower and urinary excretion of deoxypyridinoline (DPD) tended to be higher than in normal rats. Areal BMD and maximum load of the lumbar vertebrae and femoral shaft were lower in diabetic rats than in normal rats. All doses of ELD and the highest dose of ALF reduced urinary DPD excretion, but had no effect on serum OC. The 20 and 40 ng/kg doses of ELD prevented decreases in BMD and the highest dose of ELD prevented the reduction in maximum load of the lumbar vertebrae, while ALF did not change these parameters. ELD and ALF did not affect areal BMD or biomechanical strength of the femoral shaft. In diabetic rats, bone volume and trabecular thickness in the trabecular bone of the lumbar vertebrae decreased and trabecular separation increased compared to normal rats. ELD and ALF prevented diabetes-induced deterioration of trabecular microstructure. AGE content in the femoral cortical bone increased in the diabetic rats, and ELD and ALF did not change AGE content compared to the diabetic rats. These results indicated that ELD suppressed bone resorption and prevented trabecular bone loss and deterioration of trabecular microstructure, resulting in prevention of reduction in biomechanical

    Full Text Available The diagnosis of idiopathic normal pressure hydrocephalus (iNPH is still challenging. Alzheimer's disease (AD, along with vascular dementia, the most important differential diagnosis for iNPH, has several potential cerebrospinal fluid (CSF biomarkers which might help in the selection of patients for shunt treatment. The aim of this study was to compare a battery of CSF biomarkers including well-known AD-related proteins with CSF from patients with suspected iNPH collected from the external lumbar drainage test (ELD. A total of 35 patients with suspected iNPH patients were evaluated with ELD. CSF was collected in the beginning of the test, and the concentrations of total tau, ptau181, Aβ42, NFL, TNF-α, TGFβ1, and VEGF were analysed by ELISA. Twenty-six patients had a positive ELD result—that is, their gait symptoms improved; 9 patients had negative ELD. The levels of all analyzed CSF biomarkers were similar between the groups and none of them predicted the ELD result in these patients. Contrary to expectations lumbar CSF TNF-α concentration was low in iNPH patients.

    A free electron laser (FEL) uses an undulator, a set of alternating magnets producing a periodic magnetic fi eld, to stimulate emission of coherent radiation from a relativistic electron beam. The Lasers, Optical Accelerator Systems Integrated Studies (LOASIS) group at Lawrence Berkeley National Laboratory (LBNL) will use an innovative laserplasma wakefi eld accelerator to produce an electron beam to drive a proposed FEL. In order to optimize the FEL performance, the dependence on electron beam and undulator parameters must be understood. Numerical modeling of the FEL using the simulation code GINGER predicts the experimental results for given input parameters. Among the parameters studied were electron beam energy spread, emittance, and mismatch with the undulator focusing. Vacuum-chamber wakefi elds were also simulated to study their effect on FEL performance. Energy spread was found to be the most infl uential factor, with output FEL radiation power sharply decreasing for relative energy spreads greater than 0.33%. Vacuum chamber wakefi elds and beam mismatch had little effect on the simulated LOASIS FEL at the currents considered. This study concludes that continued improvement of the laser-plasma wakefi eld accelerator electron beam will allow the LOASIS FEL to operate in an optimal regime, producing high-quality XUV and x-ray pulses.

    2010-01-01

    The healthcare industry is known for constant and rapid change, highlighting the need for strong executive leadership. Within this industry, multihospital healthcare systems present particular executive leadership challenges due to their size and complexity, yet our understanding of how these executive-level health system leaders are developed has been extremely limited. The objective of this research was to study the establishment, organization, content, process, evaluation, and evolution of executive leadership development (ELD) programs in U.S. healthcare systems. Results of a national survey of health system CEOs, supplemented by interviews with multiple health system key informants, showed that ELD programs existed in around half of responding U.S. health systems and were especially prevalent among smaller systems. On average the programs were fairly new, with most having been established since 2003. ELD programs were reportedly valued by the health systems, as reflected by respondents' perceptions of program payoffs and sustained budgetary commitment. Specifically, ELD programs are believed to help further healthcare systems' strategic goals, initiate succession planning, and provide local development opportunities. In addition, the majority of program elements were reportedly worth the investment in improving executives' leadership skills and capabilities. Given the imperative to improve leadership capabilities in healthcare, ELD programs provide important opportunities to enable health systems to meet the challenges of a changing health services industry.

    Alesini, D; Garganese, C; Migliorati, M; Palumbo, L

    2001-01-01

    In this paper we present the numerical and experimental study of the electromagnetic elds that propagate in a coaxial waveguide having periodic slots in the inner conductor. The aim of the work is to estimate the e ects of the holes on the phase velocity of the eld propagating in structures like the LHC liner, and to which extent these elds can be considered synchronous with the generating beam. To this end we have performed a numerical analysis by using the MAFIA simulation code, and have obtained, for a given geometry, the ampli- tude of the slowing down of the phase velocity due to the presence of the slot array. We have then performed a set of measurements of this e ect on a simple coaxial resonator, measuring the shift of the resonance frequencies produced by the slots. This shift, related to the phase velocity, has been compared with the results obtained with the simulations.

    Tajarrod, Mohammad Hadi; Saghai, Hassan Rasooli

    2015-01-01

    The present paper casts light upon the performance of an armchair graphene nanoribbon (AGNR) field effect transistor in the presence of one-dimensional topological defects. The defects containing 5-8-5 sp(2)-hybridized carbon rings were placed in a perfect graphene sheet. The atomic scale behavior of the transistor was investigated in the non-equilibrium Green's function (NEGF) and tight-binding Hamiltonian frameworks. AGNRFET basic terms such as the on/off current, transconductance and subthreshold swing were investigated along with the extended line defect (ELD). The results indicated that the presence of ELDs had a significant effect on the parameters of the GNRFET. Compared to conventional transistors, the increase of the I on/I off ratio in graphene transistors with ELDs enhances their applicability in digital devices.

    2015-08-01

    Production of quality electron bunches using e cient ways of generation is a crucial aspect of accelerator technology. Radio frequency electron guns are widely used to generate and rapidly accelerate electron beams to relativistic energies. In the current work, we primarily study the charge generation processes of photoemission and eld emission inside an RF gun installed at Fermilab's High Brightness Electron Source Laboratory (HBESL). Speci cally, we study and characterize second-order nonlinear photoemission from a Cesium Telluride (Cs2Te) semiconductor photocathode, and eld emission from carbon based cathodes including diamond eld emission array (DFEA) and carbon nanotube (CNT) cathodes located in the RF gun's cavity. Finally, we discuss the application experiments conducted at the facility to produce soft x-rays via inverse Compton scattering (ICS), and to generate uniformly lled ellipsoidal bunches and temporally shaped electron beams from the Cs2Te photocathode.

  14. Non-Standard Hierarchies of the Runnings of the Spectral Index in Inflation

    Directory of Open Access Journals (Sweden)

    Chris Longden

    2017-03-01

    Full Text Available Recent analyses of cosmic microwave background surveys have revealed hints that there may be a non-trivial running of the running of the spectral index. If future experiments were to confirm these hints, it would prove a powerful discriminator of inflationary models, ruling out simple single field models. We discuss how isocurvature perturbations in multi-field models can be invoked to generate large runnings in a non-standard hierarchy, and find that a minimal model capable of practically realising this would be a two-field model with a non-canonical kinetic structure. We also consider alternative scenarios such as variable speed-of-light models and canonical quantum gravity effects and their implications for runnings of the spectral index.

    2016-06-01

    Full Text Available Economic Load Dispatch (ELD is the process of allocating the required load between the available generation units such that the cost of operation is minimized. The ELD problem is formulated as a nonlinear constrained optimization problem with both equality and inequality constraints. The dual-objective Combined Economic Emission Dispatch (CEED problem is considering the environmental impacts that accumulated from emission of gaseous pollutants of fossil-fuelled power plants. In this paper, an implementation of Flower Pollination Algorithm (FPA to solve ELD and CEED problems in power systems is discussed. Results obtained by the proposed FPA are compared with other optimization algorithms for various power systems. The results introduced in this paper show that the proposed FPA outlasts other techniques even for large scale power system considering valve point effect in terms of total cost and computational time.

    Full Text Available In the first lecture we briefly summarize the basics of field theory thermodynamics and critical phenomena. We then introduce the lattice gauge field theory approach to QCD at finite temperature and density, which is a non-perturbative scheme allowing first principle calculations using the QCD Lagrangian as a sole input. Some of the general concepts and idea introduced at the beginning are demonstrated by use of simple effective models of QCD. The second lecture is devoted to applications. We emphasize that current methods suffice to study the main phenomena at RHIC and LHC energies, and we discuss the ongoing theoretical efforts devoted to the solution of the sign problem which hampers the simulations of cold and dense matter. We conclude with short overview of the status of the field as of Summer 2008.

The instruments, interview, observation and field notes, were used to gather the evidences of useful oral language teaching methodologies. Results indicate that most of the methodologies utilized in the ELD and EFL programs are consistent with each other. However, the ELD teachers were more capable to provide valuable resolution of the obstacles of teaching oral language as well as the instances of delivering oral language methodologies. The researcher made an action plan targeted to findings of the following questions. 1. What materials are used to deliver oral language instruction in both countries? 2 What methodologies are the most useful and well-liked by students? 3. How are students motivated to acquire English oral language skills in both countries?

    Algorithms are a fundamental component of robotic systems. Robot algorithms process inputs from sensors that provide noisy and partial data, build geometric and physical models of the world, plan high-and low-level actions at different time horizons, and execute these actions on actuators with limited precision. The design and analysis of robot algorithms raise a unique combination of questions from many elds, including control theory, computational geometry and topology, geometrical and physical modeling, reasoning under uncertainty, probabilistic algorithms, game theory, and theoretical computer science.

    We address the forces exerted by the electromagnetic ?eld emitted by a planar uctuating source on dielectric particles that have arose much interest because of their recently shown magnetodielectric behavior. In this context, we analyze as a particular case the modi?cation of the Casimir and Van der Waals forces. We study the e?ect of the source coherence length as well as the interplay between the force from the radiated ?eld and that from the electric and magnetic dipoles induced on the particle. This allows a control of these interactions as well as of the weight and interference e?ects between the ?elds from both kinds of induced dipoles, in particular when large changes in their di?erential scattering cross section occur due to Kerker minimum forward or zero backward conditions; thus opening new paths to nanoparticle ensembling and manipulation. The influence of surface waves of the source is also studied.

    The historical developments of conformal transformations and symmetries are sketched: Their origin from stereographic projections of the globe, their blossoming in two dimensions within the eld of analytic complex functions, the generic role of transformations by reciprocal radii in dimensions higher than two and their linearization in terms of polyspherical coordinates by Darboux, Weyl's attempt to extend General Relativity, the slow rise of nite dimensional conformal transformations in classical eld theories and the problem of their interpretation, then since about 1970 the rapid spread of their acceptance for asymptotic and structural problems in quantum eld theories and beyond, up to the current AdS=CFT conjecture. The occasion for the present article: hundred years ago Bateman and Cunningham discovered the form invariance of Maxwell's equations for electromagnetism with respect to conformal space-time transformations.

    Full Text Available Abstract Background In this study we investigated (a to what extent physicians have experience with performing a range of end-of-life decisions (ELDs, (b if they have no experience with performing an ELD, would they be willing to do so under certain conditions and (c which background characteristics are associated with having experience with/or being willing to make such ELDs. Methods An anonymous questionnaire was sent to 16,486 physicians from specialities in which death is common: Australia, Belgium, Denmark, Italy, the Netherlands, Sweden and Switzerland. Results The response rate differed between countries (39–68%. The experience of foregoing life-sustaining treatment ranged between 37% and 86%: intensifying the alleviation of pain or other symptoms while taking into account possible hastening of death between 57% and 95%, and experience with deep sedation until death between 12% and 46%. Receiving a request for hastening death differed between 34% and 71%, and intentionally hastening death on the explicit request of a patient between 1% and 56%. Conclusion There are differences between countries in experiences with ELDs, in willingness to perform ELDs and in receiving requests for euthanasia or physician-assisted suicide. Foregoing treatment and intensifying alleviation of pain and symptoms are practiced and accepted by most physicians in all countries. Physicians with training in palliative care are more inclined to perform ELDs, as are those who attend to higher numbers of terminal patients. Thus, this seems not to be only a matter of opportunity, but also a matter of attitude.

    In recent years, several sound and movement recording tags have been developed to sample the acoustic fi eld experienced by cetaceans and their reactions to it. However, little is known about how tag placement and an animal’s orientation in the sound fi eld affect the reliability of on-animal...... recordings as proxies for actual exposure. Here, we quantify sound exposure levels recorded with a DTAG-3 tag on a captive harbor porpoise exposed to vessel noise in a controlled acoustic environment.

    External electric fi elds readily align birefringent block-copolymer mesophases. In this study the effect of gold nanoparticles on the electric-fi eld-induced alignment of a lamellae-forming polystyrene- block -poly(2-vinylpyridine) copolymer is assessed. Nanoparticles are homogeneously dispersed in the styrenic phase and promote the quantitative alignment of lamellar domains by substantially lowering the critical field strength above which alignment proceeds. The results suggest that the electric-fi eldassisted alignment of nanostructured block copolymer/nanoparticle composites may offer a simple way to greatly mitigate structural and orientational defects of such fi lms under benign experimental conditions.

    Full Text Available Leadership is one of the best examples for an ubiquitous research topic, as it is studied both as a social phenomenon as well as a theoretical concept (Hackman and Wageman, 2007, being studied in relation with different research fi elds, ranging from politics, public administration, management, social and organizational change, human motivation (and the list could go on. This has led some scholars to claiming that leadership has been the source of more extensive investigation than almost any other aspect of human behavior (de Vries, 1993. The interest then in public sector leadership comes only natural to any researcher in the fi eld of public administration. Our main purpose was to identify and analyze what has been done on the topic of public sector leadership, specifi cally for Romania, in the past ten years. We focused on three major variables: theoretical framework used, authorship nationality, and quality of research. Results indicate that Romanian authors and Romania are missing from top tier journals in the fi eld of public administration. Indirectly, results raise questions about general research capacity in the fi eld of public administration of Romanian scholars.

    2011-10-01

    Sea urchin embryo-larval development (ELD) and fertilization tests have been widely used in ecotoxicity studies and are included in regulatory frameworks. Biological processes occur naturally within a range of salinity that depends on the species considered. In an attempt to determine the optimum range of salinity, ELD and fertilization bioassays were performed at different salinities (15-40.5‰) with two species of Atlantic sea urchin: Arbacia lixula and Paracentrotus lividus. In the ELD assay, the optimum range of salinity was wider for A. lixula (29-35.5‰) than for P. lividus (29-33‰). In the fertilization assay with P. lividus as a bioindicator species, the highest percentage of fertilization (90%) was obtained at salinities of between 29 and 33‰. More research on A. lixula is required, since the fertilization success was below 60%. The results of the present study demonstrate that salinity may be a confounding factor in interpreting ELD test results. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Hybrid Megalobrama amblycephala × Culter alburnus represents a population newly formed by interspecific crossing between two different genera. Here we assessed the expression pattern of mRNA and small RNA in newly formed F1, F2 and their progenitors. Large amounts of nonadditively expressed protein-coding genes showed parental expression level dominance (ELD). Interestingly, the ELD pattern could inherit from F1 to F2, which guaranteed a stable appearance in progenies. The ELD-B genes were found to contribute to cell development, while the ELD-T genes were enriched in function of stress and adaptability. microRNAs (miRNA) also had similar expression patterns to genes. A high proportion of miRNAs showed nonadditive expression upon hybridization, and were found to target important genes with diverse roles potentially involved in stress adaption and development. Taken together, the gene and miRNA expression divergence contributes to heterosis in the newly formed hybrid, promising the successful existence of hybrid speciation. PMID:26346824

  10. Nonword Repetition in Spanish-Speaking Toddlers with and without Early Language Delays.

    Guiberson, Mark; Rodríguez, Barbara L

    2015-01-01

    Nonword repetition (NWR) studies with English-speaking toddlers indicate favorable diagnostic accuracy for identifying early language delays and strong associations with early vocabulary. While scarce, studies of Spanish NWR have revealed strong diagnostic accuracy with preschool- and school-age children. This study aimed to (1) establish the association between Spanish NWR and early linguistic measures, (2) compare the Spanish NWR skills of typical Spanish-speaking toddlers and those of toddlers with early language delays (ELD), and (3) establish the diagnostic accuracy of a Spanish NWR task. Sixty-five Spanish-speaking toddlers were given a NWR task and a language assessment while parents completed a vocabulary checklist and reported their child's longest utterances. NWR scores were moderately correlated with vocabulary and language. The ELD group had significantly lower NWR scores than peers, and 68% of the sample was classified correctly, with desirable sensitivity but inadequate specificity obtained. Findings from this study revealed developmental trends in Spanish-speaking toddlers' ability to repeat nonwords and that most toddlers were not able to repeat 4- and 5-syllable nonwords. Furthermore, Spanish-speaking children with ELD had more difficulties with NWR than typical peers. The diagnostic accuracy results indicated that the clinical use of a Spanish NWR task for toddlers can serve to detect early language-learning difficulties, especially if used as one of multiple diagnostic sources of information to establish ELD. © 2016 S.

  13. Exploring the Physics Limitations of Compact High Gradient Accelerating Structures Simulations of the Electron Current Spectrometer Setup in Geant4

    CERN Document Server

    Van Vliet, Philine Julia

    2017-01-01

    The high field gradient of 100 MV/m that will be applied to the accelerator cavities of the Compact Linear Collider (CLIC), gives rise to the problem of RF breakdowns. The field collapses and a plasma of electrons and ions is being formed in the cavity, preventing the RF field from penetrating the cavity. Electrons in the plasma are being accelerated and ejected out, resulting in a breakdown current up to a few Amp`eres, measured outside the cavities. These breakdowns lead to luminosity loss, so reducing their amount is of great importance. For this, a better understanding of the physics behind RF breakdowns is needed. To study these breakdowns, the XBox 2 test facility has a spectrometer setup installed after the RF cavity that is being conditioned. For this report, a simulation of this spectrometer setup has been made using Geant4. Once a detailed simulation of the RF field and cavity has been made, it can be connected to this simulation of the spectrometer setup and used to recreate the data that has b...

  16. Alternating current thin-film electroluminescence of GaN:Er

    Science.gov (United States)

    Heikenfeld, J.; Steckl, A. J.

    2000-11-01

    Thin-film electroluminescence has been obtained from GaN:Er deposited directly on amorphous dielectric layers. Electroluminescent device (ELD) structures consisting of metal/dielectric/GaN:Er/dielectric were fabricated on p+-Si substrates. In contrast to previous GaN:Er ELDs which used epitaxial growth conditions on crystalline substrates and were operated under direct current bias, these ELDs were operated under alternating current bias. Under bias conditions of 170 peak voltage (Vp) and frequencies of 10 and 100 kHz, the ELDs exhibit a luminance of 50 and 300 cd/m2, respectively. The emission spectra, which originate from Er3+ 4f-4f transitions, consist of dominant green emission at ˜537/558 nm accompanied by violet (415 nm) and infrared (1.5 μm) peaks. The violet emission peak indicates that hot carriers can gain up to ˜3 eV energy for a Vp corresponding to 1.5 MV/cm applied field. The emitted intensity initially increases linearly with frequency, followed by a trend towards saturation. The frequency for 3 dB reduction from the linear relation is at ˜65 kHz for the visible emission and ˜8 kHz for the infrared emission.

  20. Permissive Hypotension: Potentially Harmful in the Elderly? A National Trauma Data Bank Analysis.

    Science.gov (United States)

    Bridges, Lindsay C; Waibel, Brett H; Newell, Mark A

    2015-08-01

    Permissive hypotension is a component of damage control resuscitation that aims to provide a directed, controlled resuscitation, while countering the "lethal triad." This principle has not been specifically studied in elderly (ELD) trauma patients (≥55 years). Given the ELD population's lack of physiologic reserve and risk of inadequate perfusion with "normal" blood pressures, we hypothesized that utilized a permissive hypotension strategy in ELD trauma patients would result in worse outcomes compared with younger patients (18-54 years). A retrospective review of National Trauma Data Bank reports from 2009 and 2010, identifying critically ill patients undergoing a "damage control laparotomy," was performed to determine the effect of age and systolic blood pressure on outcome. Logistic regression analysis, including evaluation of an interaction between age and admission blood pressure, was performed on mortality using admission demographics, physiology, injury severity, mechanism of injury, and in-hospital complications. Although there was a higher likelihood of death with greater age, lower admission systolic blood pressure, lower Glasgow Coma Score, increased injury severity score, and acute renal failure, a synergistic effect of age and blood pressure on mortality was not identified. Permissive hypotension appears to be a possible management strategy in ELD trauma patients.

  15. Programmable Input for Nanomagnetic Logic Devices

    Schmitt-Landsiedel D.

    2013-01-01

    Full Text Available A programmable magnetic input, based on the magnetic interaction of a soft and hard magnetic layer is presented for the first time. Therefore, a single-domain Co/Pt nanomagnet is placed on top of one end of a permalloy bar, separated by a thin dielectric layer. The permalloy bar of the introduced input structure is magnetized by weak easy-axis in-plane fields. Acting like a ’magnetic amplifier’, the generated fringing fields of the permalloy pole are strong enough to control the magnetization of the superimposed Co/Pt nanomagnets, which have high crystalline perpendicular magnetic anisotropy. This magnetostatic interaction results in a shift of the hysteresis curve of the Co/Pt nanomagnet, measured by magneto-optical Kerr microscopy. The Co/Pt nanomagnet is fixed by the fringing field of the permalloy and thereby not affected by the magnetic power clock of the Nanomagnetic Logic system. MFM measurements verify the functionality of the programmable magnetic input structure. The fringing fields are extracted from micromagnetic simulations and are in good agreement with experimental results. The introduced input structure enables switching the logic functionality of the majority gate from NAND to NOR during runtime, offering programmable Nanomagnetic Logic.

    2009-10-01

    We investigated on a nationwide level the attitudes of nurses towards end-of-life decisions (ELDs) that may hasten death and towards their role in those decisions. We took a representative random sample of 6000 nurses in Flanders, Belgium. Response rate was 62.5%. Most nurses agreed with the practice of withholding/withdrawing potentially life-prolonging treatments (93%), with decisions to alleviate symptoms with possible life-shortening side effects (96%) and with the practice of euthanasia (92%). Their support for the different decisions existed regardless of whether they had cared for terminally ill patients or not. Most nurses also thought that they have an important role to play especially in the ELD-making process. Nurses' views on their proper role in the administration of drugs in euthanasia and continuous deep sedation showed a large dispersal. Overall, nurses' work setting determines their opinions on nurses' role in ELDs. In conclusion, nurses accept a wide variety of ELDs being practiced with terminally ill patients.

  18. varying elastic parameters distributions

    KAUST Repository

    Moussawi, Ali

    2014-12-01

    The experimental identication of mechanical properties is crucial in mechanics for understanding material behavior and for the development of numerical models. Classical identi cation procedures employ standard shaped specimens, assume that the mechanical elds in the object are homogeneous, and recover global properties. Thus, multiple tests are required for full characterization of a heterogeneous object, leading to a time consuming and costly process. The development of non-contact, full- eld measurement techniques from which complex kinematic elds can be recorded has opened the door to a new way of thinking. From the identi cation point of view, suitable methods can be used to process these complex kinematic elds in order to recover multiple spatially varying parameters through one test or a few tests. The requirement is the development of identi cation techniques that can process these complex experimental data. This thesis introduces a novel identi cation technique called the constitutive compatibility method. The key idea is to de ne stresses as compatible with the observed kinematic eld through the chosen class of constitutive equation, making possible the uncoupling of the identi cation of stress from the identi cation of the material parameters. This uncoupling leads to parametrized solutions in cases where 5 the solution is non-unique (due to unknown traction boundary conditions) as demonstrated on 2D numerical examples. First the theory is outlined and the method is demonstrated in 2D applications. Second, the method is implemented within a domain decomposition framework in order to reduce the cost for processing very large problems. Finally, it is extended to 3D numerical examples. Promising results are shown for 2D and 3D problems.

  19. On the preparation, characterization, and application of Janus spheres

    Science.gov (United States)

    Cui, Jingqin

    Surface-anisotropic Janus particles are a new class of materials with interesting properties that have attracted great attention recently. There have been many reports on the manufacture of Janus particles. However, most of them employ the traditional high-cost vapor phase deposition to obtain an asymmetric surface modification of particles. In this thesis, a novel templating process is developed for the manufacturing of Janus spheres via the economic and mild electroless deposition (ELD) method. Templated micron- and submicron-sized polystyrene (PS) spheres are modified with a silver cap composed of 50-200 nm nanoparticles (NPs) through the ELD process. The deposits are found to be stable over time and under physical treatment. Further, the study determines that the substrate sphere curvature influences the ELD modification due to the functional group coverage and distribution as well as the size ratio of the substrate sphere to the NPs deposit. Gold, palladium and titanium oxide particles are successfully deposited onto PS spheres using the same templating process and nanoparticle synthesis methods from literatures in the electroless/wet chemical deposition. Modifications obtained with the ELD conditions studied exhibit a rough surface compared to the vapor-phase modified surfaces. The surface roughness is controlled by varying the ELD reaction conditions to adjust the amount of deposit and the size distribution of the NPs deposited. The assembly of Janus spheres with smooth caps produces planar 2-D structures while spheres with rougher caps tend to form 3-D cluster structures, implying that the surface morphology has an effect on the sphere-sphere interactions. The assembly of new dual-cap/mono-belt Janus particles prepared by combining the vapor phase and ELD processes confirms that the surface roughness influences the orientation of the Janus spheres during assembly. Janus spheres are then incorporated into electroactive polymers as fillers to enhance the

  20. Some new approaches to the study of the Earth's magnetic field reversals

    Directory of Open Access Journals (Sweden)

    2003-06-01

    Full Text Available Paleomagnetic studies clearly show that the polarity of the magnetic fi eld has been subject to reversals. It is generally assumed that polarity intervals are exponentially distributed. Here, the geomagnetic polarity reversal record, for the past 166 Ma, is analysed and a new approach to the study of the reversals is presented. In detail, the occurrence of 1/f-noise in the Power Spectral Density (PSD, relative to geomagnetic fi eld reversals, the existence of a Zipf's law behaviour for the cumulative distribution of polarity intervals, and the occurrence of punctuated equilibrium, as shown by a sort of Devil's staircase for the reversal time series, are investigated. Our results give a preliminary picture of the dynamical state of the geomagnetic dynamo suggesting that the geodynamo works in a marginally stable out-of-equilibrium confi guration, and that polarity reversals are equivalent to a sort of phase transition between two metastable states.

    2004-01-01

    While preparing and teaching 'Introduction to Geodesy I and II' to - dergraduate students at Stuttgart University, we noticed a gap which motivated the writing of the present book: Almost every topic that we taughtrequiredsomeskillsinalgebra,andinparticular,computeral- bra! From positioning to transformation problems inherent in geodesy and geoinformatics, knowledge of algebra and application of computer algebra software were required. In preparing this book therefore, we haveattemptedtoputtogetherbasicconceptsofabstractalgebra which underpin the techniques for solving algebraic problems. Algebraic c- putational algorithms useful for solving problems which require exact solutions to nonlinear systems of equations are presented and tested on various problems. Though the present book focuses mainly on the two ?elds,theconceptsand techniquespresented hereinarenonetheless- plicable to other ?elds where algebraic computational problems might be encountered.

    2012-09-01

    Full Text Available Unmanned aerial vehicles (UAV and micro air vehicles (MAV are already intensively used in geodetic applications. State of the art autonomous systems are however geared towards the application area in safe and obstacle-free altitudes greater than 30 meters. Applications at lower altitudes still require a human pilot. A new application field will be the reconstruction of structures and buildings, including the facades and roofs, with semi-autonomous MAVs. Ongoing research in the MAV robotics field is focusing on enabling this system class to operate at lower altitudes in proximity to nearby obstacles and humans. PIXHAWK is an open source and open hardware toolkit for this purpose. The quadrotor design is optimized for onboard computer vision and can connect up to four cameras to its onboard computer. The validity of the system design is shown with a fully autonomous capture flight along a building.

    Full Text Available New image processing methodologies and algorithms have greatly contributed to the signi cant progress in three-dimensional electron microscopy (3DEM of biological complexes we have seen over the last decades. Naturally, the availability of accurate procedures for the objective testing of new algorithms is a crucial requirement for the further advancement of the eld. A good and accepted testing work ow involves the generation of realistic 3DEM-like maps of biological macromolecules from which some measure of ground truth can be derived, ideally because their 3D atomic structure is already known. In this work we propose a very accurate generation of maps using atomic form factors for electron scattering. We thoroughly review current approaches in the eld, quantitatively demonstrating the bene ts of the new methodology. Additionally, we study a concrete example of the use of this approach for hypothesis testing in 3D Electron Microscopy.

    Full Text Available We provide recent information on the richness of mammals along the agroecosystems of the Rio da Várzea Basin, Rio Grande do Sul, Brazil. We used different fi eld techniques to confi rm the occurrence of 46 mammal species in this area. Nine species are threatened in at least one of the three "red lists" at state, national and global levels. Adding the up-to-date results obtained in the fi eld to available data, mainly for conservation units, we present a richness of 85 species recorded for the basin. This number represents about 50% of mammals documented for Rio Grande do Sul state. The results suggest the importance of maintaining protected areas in altered regions, confi rming the relevance of inventories of local fauna as a fi rst approach to specifi c studies addressed to distribution, systematics, cytogenetics, physiology, population and community ecology.

    Laboratory Studies of Dynamos: Executive Summary. The self-generation of magnetic fields by astrophysical bodies like planets, stars, accretion disks, galaxies, and even galaxy clusters arises due to a mechanism referred to as a homogeneous dynamo. It is quite simple to demonstrate the generation of a magnetic fi eld from a rotating copper disk coupled with a coil of wire, a device known as the homopolar dynamo. The device works like a magnetic fi eld ampli er with a feedback circuit: the differential rotation of a metal disk past an infinitesimally small seed magnetic field induces currents in the disk which, when coupled to a coil winding, can amplify the field until it becomes strong enough to slow the rotation of the disk. What is remarkable is that the same type of circuit may be achieved in a flowing conducting fluid such as a liquid metal in the case of planetary dynamos or a plasma in the case of astrophysical dynamos. The complexity of describing planetary and stellar dynamos despite their ubiquity and the plethora of observational data from the Earth and the Sun motivates the demonstration of a laboratory homogenous dynamo. To create a homogenous dynamo, one first needs a su fficiently large, fast flow of a highly conducting fluid that the velocity shear in the fluid can bend magnetic field lines. With a high Rm-flow, the magnetic fi eld can be ampli ed by the stretching action provided by di fferential rotation. The other critical ingredient is a flow geometry that provides feedback so that the ampli ed eld reinforces the initial in nitesimal seed field - a mechanism that recreates the feedback provided by the coil of wire in the homopolar dynamo. In the Madison Dynamo Experiment, this combination of magnetic ampli cation and feedback is feasible in the simple geometry of two counter-rotating helical vortices in a 1 meter-diameter spherical vessel lled with liquid sodium. For an optimal helical pitch of the flow the threshold for exciting a dynamo is

    In process control, data are exchanged vertically from the fi eld level to the control system and horizontally within the process control levels as well as within neighboring phases of the life cycle. Open, scalable system architectures demand standardized communication structures that have adjusted to the increasing requirements to communication in automation of plants of process industry in the last decades. Technologically related systems and solutions of other application fi elds have influenced especially the communication within process control. In the near future, Ethernet applications and wireless communication of other domains are capable to be applied in process engineering. The paper deals with the history of recent communication standards and topologies and tries to give an outlook on the meaning of new technologies. Emphasis is placed on the physical layer, i.e. the communication structure. (orig.)

    2001-09-01

    Visible emission has been observed from rare-earth (RE)-doped GaN electroluminescent devices (ELDs) as-grown near room temperature on Si (50-100 °C): red from GaN:Eu, green from GaN:Er, and blue from GaN:Tm. Green emission at 537/558 nm from GaN:Er ELD had a measured brightness of ˜230 cd/m2 at 46 V bias. X-ray diffraction indicates that the low-temperature-grown GaN:Er structure was oriented with the c axis perpendicular to the substrate. Scanning electron and atomic force microscopy indicate that the films had a rough surface and a compact structure consisting of small grains. Electroluminescence intensity of GaN:RE was significantly improved with postgrowth annealing. For GaN:Er films, after 800 °C annealing, the green emission brightness efficiency increased by ˜10×.

  1. Magnetorotational Explosions of Core-Collapse Supernovae

    Directory of Open Access Journals (Sweden)

    Gennady S. Bisnovatyi-Kogan

    2014-12-01

    Full Text Available Core-collapse supernovae are accompanied by formation of neutron stars. The gravitation energy is transformed into the energy of the explosion, observed as SN II, SN Ib,c type supernovae. We present results of 2-D MHD simulations, where the source of energy is rotation, and magnetic eld serves as a "transition belt" for the transformation of the rotation energy into the energy of the explosion. The toroidal part of the magnetic energy initially grows linearly with time due to dierential rotation. When the twisted toroidal component strongly exceeds the poloidal eld, magneto-rotational instability develops, leading to a drastic acceleration in the growth of magnetic energy. Finally, a fast MHD shock is formed, producing a supernova explosion. Mildly collimated jet is produced for dipole-like type of the initial field. At very high initial magnetic field no MRI development was found.

    2011-05-31

    A nonlinear two-dimensional theory is developed for thin magnetoelastic lms capable of large deformations. This is derived directly from three-dimensional theory. Signi cant simpli cations emerge in the descent from three dimensions to two, permitting the self eld generated by the body to be computed a posteriori. The model is specialized to isotropic elastomers with two material models. First weak magnetization is investigated leading to a free energy where magnetization and deformation are un-coupled. The second closely couples the magnetization and deformation. Numerical solutions are obtained to equilibrium boundary-value problems in which the membrane is subjected to lateral pressure and an applied magnetic eld. An instability is inferred and investigated for the weak magnetization material model.

    2013-09-01

    DIXI utilizes pulse-dilation technology to achieve x-ray imaging with temporal gate times below 10 ps. The longitudinal magnetic eld used to guide the electrons during the dilation process results in a warped image, similar to an optical distortion from a lens. Since the front end, where x-rays are converted into electrons at the beginning of the magnetic eld, determines the temporal resolution these distortions in uence the temporal width of the images at the back end, where it is captured. Here we discuss the measurements and methods used to reverse the magnetic warp e ect in the DIXI data. The x-ray measurements were conducted using the COMET laser facility at the Lawrence Livermore National Laboratory.

    Karthikeyan, M; Raja, T Sree Ranga

    2015-01-01

    Economic load dispatch (ELD) problem is an important issue in the operation and control of modern control system. The ELD problem is complex and nonlinear with equality and inequality constraints which makes it hard to be efficiently solved. This paper presents a new modification of harmony search (HS) algorithm named as dynamic harmony search with polynomial mutation (DHSPM) algorithm to solve ORPD problem. In DHSPM algorithm the key parameters of HS algorithm like harmony memory considering rate (HMCR) and pitch adjusting rate (PAR) are changed dynamically and there is no need to predefine these parameters. Additionally polynomial mutation is inserted in the updating step of HS algorithm to favor exploration and exploitation of the search space. The DHSPM algorithm is tested with three power system cases consisting of 3, 13, and 40 thermal units. The computational results show that the DHSPM algorithm is more effective in finding better solutions than other computational intelligence based methods.

    Full Text Available This paper presents the application of modified cuckoo search algorithm (MCSA for solving economic load dispatch (ELD problems. The MCSA method is developed to improve the search ability and solution quality of the conventional CSA method. In the MCSA, the evaluation of eggs has divided the initial eggs into two groups, the top egg group with good quality and the abandoned group with worse quality. Moreover, the value of the updated step size in MCSA is adapted as generating a new solution for the abandoned group and the top group via the Levy flights so that a large zone is searched at the beginning and a local zone is foraged as the maximum number of iterations is nearly reached. The MCSA method has been tested on different systems with different characteristics of thermal units and constraints. The result comparison with other methods in the literature has indicated that the MCSA method can be a powerful method for solving the ELD.

    Fluckiger, Lorenzo Jean Marc E; Utz, Hans Heinrich

    2013-01-01

    This paper presents the lessons learned from six years of experiments with planetary rover prototypes running the Service Oriented Robotic Architecture (SORA) developed by the Intelligent Robotics Group (IRG) at the NASA Ames Research Center. SORA relies on proven software engineering methods and technologies applied to space robotics. Based on a Service Oriented Architecture and robust middleware, SORA encompasses on-board robot control and a full suite of software tools necessary for remotely operated exploration missions. SORA has been eld tested in numerous scenarios of robotic lunar and planetary exploration. The experiments conducted by IRG with SORA exercise a large set of the constraints encountered in space applications: remote robotic assets, ight relevant science instruments, distributed operations, high network latencies and unreliable or intermittent communication links. In this paper, we present the results of these eld tests in regard to the developed architecture, and discuss its bene ts and limitations.

    Particle accelerators are constructed and operated for a wide variety of applications. In particle physics - the branch of physics that studies the elementary constituents of matter and forces between them - high energy accelerators are used to look deep into the structure of matter. Medical particle accelerators are used for example in medicine to treat tumours [31], in imaging techniques such as Positron Emission Tomography (PET) [24], or for the radio-isotopes production. They also serve in many other industrial branches, e.g. geology, radiocarbon dating [39], molecular complex spectroscopy, lithography, food preservation etc. The eld of accelerator technology draws knowledge and expertise from a wide range of scientic disciplines and uses the latest technical knowledge. The incomplete list of covered disciplines includes mathematics, physics, electronics, computing, electromagnetic eld technology, microwave technology, cryogenics, vacuum technology, special materials, mechanical engineering or civil engin...

    What is the topic of this book? The title may seem puzzling to many since it seemingly refers to a non-existing fi eld of study. No academic program or any scientifi c journal caters to and carries the torch of such a domain of research. “Social theory on consumption” is a neologism as a denominator....... The irony becomes even thicker when the title also seems to assume that there is such a thing as canonical authors in this non-existing fi eld of study. Already at this point, the reader may have started to expect some kind of avant-garde scientifi c experiment – or a public joke – in the legacy of John Cage...

  19. Applications of numerical relativity: critical behavior and black hole containing space-times

    CERN Document Server

    Evans, C R

    1993-01-01

    Several recent applications of numerical relativity techniques are described. The first is the remarkable evidence of critical phenomena in gen- eral relativity associated with gravitational collapse of massless fields. We discuss the two currently known examples of such critical behavior: gravi- tational collapse of massless scalar field and of axisymrnetric gravitational waves, A second application is discussed, in which numerical relativity tech- niques are used to probe the interaction between strong gravitational waves and black holes. Finally, a numerical approach to computing initial data for spacetimes that contain twr) black holes is described. Such initial data may ultiiriately serve as a starting point for the comptniaticm of the orbital decay and <::_:alescence of a black hole binary,

    1993-01-01

    Abstract. We describe a method for the numerical solution of Einstein’ equations for the dynamical evolution of a collisionless gas of particles in gen eral relativity. The gravitational field can be arbitrarily strong and particle velocities can approach the speed of light. The computational method uses the tools of numerical relativity and N—body particle simulation to follow the full nonlinear behavior of these systems. Specifically, we solve the Vlasov equation in general relativity by particle simulation. The gravitational field is integrated using the 3 + l formalism of Arnowitt, Deser, and Misner. One application of our method is the study of headeon collisions of relativistic clusters. We have constructed and followed the evolution of three classes of initial configurations: spheres of particles at rest; spheres of particles boosted towards each other; and spheres ol‘ particles in circular orbits about their re spective centers, in the first two cases, the spheres implode towards their cente...

  1. Field-reversed bubble in deep plasma channels for high quality electron acceleration

    CERN Document Server

    Pukhov, A; Tueckmantel, T; Thomas, J; Yu, I; Kostyukov, Yu

    2014-01-01

    We study hollow plasma channels with smooth boundaries for laser-driven electron acceleration in the bubble regime. Contrary to the uniform plasma case, the laser forms no optical shock and no etching at the front. This increases the effective bubble phase velocity and energy gain. The longitudinal field has a plateau that allows for mono-energetic acceleration. We observe as low as 10−3 r.m.s. relative witness beam energy uncertainty in each cross-section and 0.3% total energy spread. By varying plasma density profile inside a deep channel, the bubble fields can be adjusted to balance the laser depletion and dephasing lengths. Bubble scaling laws for the deep channel are derived. Ultra-short pancake-like laser pulses lead to the highest energies of accelerated electrons per Joule of laser pulse energy.

    2009-05-01

    The aim of the study was to investigate attitudes of secondary school students towards acceptability of requests by minors for end-of-life decisions (ELDs) with a possible life-shortening effect: non-treatment decisions, potentially life-shortening alleviation of pain and symptoms (APS) and euthanasia. A cross-sectional survey was conducted among second and fourth grades students in 20 secondary schools in Flanders, Belgium. An anonymous structured questionnaire was administered to measure attitudes towards acceptability of requests for euthanasia and other ELDs, towards the right to be informed about terminal prognosis and their own desire to be informed. In total, 1769 students participated. In case of a terminal patient, 61% found a request for euthanasia acceptable, 60% a request for APS and 69% a request for non-treatment decision, compared with 18% (euthanasia) and 50% (APS) in case of a non-terminal patient. Acceptance was highest among: boys, participants older than 14 years and participants from general as opposed to technical and vocational education. Sixty-six per cent said the parents' opinion not being asked was a circumstance that should hold back a physician from administering a lethal drug. Ninety per cent of participants thought a minor has the right to be informed about terminal prognosis of a disease while 78% would like to be informed themselves. Attitudes towards ELD requests varied with case and participant characteristics and type of ELD. The studied adolescents have a clear wish to be informed about terminal prognosis. Physicians and caregivers should adequately involve adolescents in decision making and tailor prognosis-related information to their needs and level of competency.
