    To describe the radiological features of pulmonary tuberculosis (TB) in patients infected with human immunodeficiency virus (HIV) and its correlation with the blood CD4 cell count. We present 44 HIV+patients, 24 with CD4 cell counts of less than 200 cells/mm''3 (group A) and 20 in whom the CD4 counts surpassed this level (group B). We also assessed the chest x-ray images to determine whether or not there was any correlation with the blood CD4 cell counts. Fisher's exact test was used for the statistical study of the differences in the radiological findings in the two groups. The incidence of atypical features was significantly greater in the patients with CD4 cell counts of less than 200 cells/mm''3 (group A) than in those with CD4 counts of over 200 cells/mm''3 (group B). Among HIV+patients, those with a more intact immune status were more likely to present lung x-ray images typical of post-primary TB, with cavitary lesions in upper lobes. The group of patients in whom the immune deficiency was more marked showed a greater incidence of atypical pulmonary findings, more characteristics of primary TB. (Author)

    In this work the efficiency calibration curves of thin-window and low background gas-flow proportional counters were determined for calibration standards with different energies and different absorber thicknesses. For the gross alpha counting we have used {sup 241}Am and natural uranium standards and for the gross beta counting we have used {sup 90}Sr/{sup 90}Y and {sup 137}Cs standards in residue thicknesses ranging from 0 to approximately 18 mg/cm{sup 2}. These sample thicknesses were increased with a previously determined salted solution prepared simulating the chemical composition of the underground water of IPEN The counting efficiency for alpha emitters ranged from 0,273 +- 0,038 for a weightless residue to only 0,015 +- 0,002 in a planchet containing 15 mg/cm{sup 2} of residue for {sup 241}Am standard. For natural uranium standard the efficiency ranged from 0,322 +- 0,030 for a weightless residue to 0,023 +- 0,003 in a planchet containing 14,5 mg/cm{sup 2} of residue. The counting efficiency for beta emitters ranged from 0,430 +- 0,036 for a weightless residue to 0,247 +- 0,020 in a planchet containing 17 mg/cm{sup 2} of residue for {sup 137}Cs standard. For {sup 90}Sr/{sup 90}Y standard the efficiency ranged from 0,489 +- 0,041 for a weightless residue to 0,323 +- 0,026 in a planchet containing 18 mg/cm{sup 2} of residue. Results make evident the counting efficiency variation with the alpha or beta emitters energies and the thickness of the water samples residue. So, the calibration standard, the thickness and the chemical composition of the residue must always be considered in the gross alpha and beta radioactivity determination in water samples. (author)

    Saint Eligius became the saint patron of farriers and veterinarians in the 13th century. This was first mentioned by Jordanus Ruffus, emperor Frederic the 2nd's equerry, who refers to a gregorian hymnal dedicated to Eligius. The legend says that Eliguis amputated a horse's foot, shoed it and placed it back on the horse's leg. This legend might have replaced the Germanic cult described in the incantations of Merseburg. In Switzerland the veneration of Eligius is particularly spread in the canton of Lucerne.

    Full Text Available El artículo evalúa las principales tesis y críticas de la teoría del control patronal a la luz del desenvolvimiento actual del capitalismo. Analiza la consistencia de ese enfoque con la teoría marxista y contrasta el aporte de Braverman con problemas de la visión neoclásica y la Teoría de la Regulación. El texto también revisa el alcance asignado al concepto de taylorismo en función de la segmentación e intelectualización actual del trabajo. Estudia en qué sentido Braverman privilegió la problemática de la resistencia al análisis del consentimiento e indaga cómo abordó la relación entre los procesos de trabajo y valorización. También se señalan aciertos, en la medición de las calificaciones por el grado de dominio en la comprensión de la tarea realizada. Pero se destaca la problemática relación de los pronósticos de descalificación absoluta con el concepto de miseria creciente. Se subrayan las implicancias políticas de esta tesis. El artículo pondera del enfoque totalizador de Braverman y su énfasis en la centralidad y no el fin del trabajo. Destaca como su mirada permite comprender el trasfondo confiscatorio de la precarización actual del empleo.

    Full Text Available Objective – To test a metric for library use, that could be comparable to metrics used by competing government departments, for ease of understanding by policy makers. Design – Four types of data were collected and used: Time-diaries, exit surveys, gate counts, and circulation statistics. Setting – A large public library in British Columbia, Canada. Subjects – Time-diary subjects were 445 patrons checking out materials; exit survey subjects were 185 patrons leaving the library. Methods – A paper-based time diary, prototypes of which were tested, was given to patrons who checked out library materials during a one-week period. These patrons were charged with recording the use of the checked-out items during the entire three-week loan period. From this information, the average number of hours spent with various types of loaned material (print and audio/DVD was calculated. The average number of hours spent per item type was then applied to the circulation statistics for those items, across a month, to get a total of hours spent using all circulated material during that month. During the same one-week period of time-diary distribution, exit surveys were conducted by library staff with patrons leaving the library, asking them how long they had spent in the library during their current visit. The average number of minutes per visit was calculated and then applied to the gate count for the month, to get a total number of minutes/hours spent “resident” in the library that month. Adding the totals, a grand total of patron time-use hours was calculated. A monetary value was applied per hour, using the results of a contingent valuation study from Missoula, Montana (Dalenberg et al., 2004, in order to convert hours of library benefit into a dollar figure. Main Results – There was a 24% response rate for the time diaries (106/445. The diary entries yielded an average of 3.5 hours of time-use per print item, and 1.9 hours per DVD. The range for

    Differences in service preferences between patrons of supermarket and chain pharmacies were determined. Subjects fell into two groups: patrons of a supermarket chain's pharmacies and patrons of the same supermarket chain who patronized other community chain pharmacies for prescription drug purchases. Subjects were asked to prioritize services in terms of convenience and impact on pharmacy selection. Differences in service preferences emerged. Community pharmacy patrons were more likely to rate easy navigation through a pharmacy and 24 X 7 hours of operation as key services. Supermarket pharmacy patrons were more likely to rate one-stop shopping and adequate hours of operation as priorities. Both groups rated basic services such as maintenance of prescription and insurance information as priorities. Pharmacies should stress the delivery of basic services when trying to attract customers.

  14. Mars by Way of Storytellers and Patrons

    Science.gov (United States)

    Polk, C.

    A business model is presented in which space-themed entertainment and educational media are harnessed to the goal of designing and financing the establishment of a self-sustaining Mars outpost. The model draws from two precedents: (i) The National Geographic Society's use of media sales to fund research and (ii) the historical role of patrons in the process of creativity. These precedents are combined in an international non-governmental organization (INGO) that is governed by the individuals who participate in the media businesses branded by the INGO - these individuals constitute a patron base of several tens of millions. Requiring only modest penetration into global media markets, expenditures of USD 5 billion per year (in 2008 dollars) can commence in 2025 and continue at an accelerating rate until the Mars outpost is established. The financing approach utilized, combined with a decision authority that is free to consider a broad range of solutions, will advance the technical state-of-the-art and result in an Earth-Mars infrastructure capable of expanding the initial Mars outpost into humanity's first second home.

  2. Patron-driven acquisitions history and best practices

    CERN Document Server

    2011-01-01

    About 40 percent of the books academic libraries purchase in traditional ways never circulate and another 40 percent circulate fewer than three times. By contrast, patron-driven acquisition allows a library to borrow or buy books only when a patron needs them. In a typical workflow, the library imports bibliographic records into its catalogue at no cost. When a patron finds a patron-driven record in the course of research, a short-term loan can allow him to borrow the book, and the transaction charge to the library will be a small percentage of the list price. Typically, a library will automatically buy a book on a third or fourth use. The contributions in this volume, written by experts, describe the genesis and brief history of patron-driven acquisitions, its current status, and its promise.

    Otorhinolaryngology is one of the few medical specialities which has a patron saint, Saint Blase (born 317-AD). He was a Doctor and Bishop in Sebaste, Armenia, and he suffered martyrdom under the rule of the Roman Emperor Licinio (Iliria 250 AD - Tsalonica 325 AD). He was acknowledged as having the ability to protect people against throat infections, after curing a child who had choked on a fishbone. The feast of Saint Blase is on February 3rd, and it is celebrated all over the Western world. There are many other Saints related to our speciality, who protect people against ear, nose and throat disorders. We have reviewed the world literature on this subject.

    For over a decade, some academic libraries have been purchasing, rather than borrowing, recently published books requested by their patrons through interlibrary loan. These books had one circulation guaranteed and so appealed to librarians who were concerned about the large percentage of books selected and purchased by librarians but never checked out by their patrons. Early assessments of the projects indicated that patrons selected quality books that in many cases were cross disciplinary and covered emerging areas of scholarly interest.

    The Direccion de Vigilancia Radiologica (DVR) of the Comision Nacional de Seguridad Nuclear y Salvaguardias (CNSNS) de Mexico, performs several function for environmental radiation monitoring. One of these functions is the permanent monitoring of the environmental gamma radiation. For this, it implemented the Red Nacional Automatica de Monitoreo Radiologico Ambiental (RENAMORA) - the National Automated Network for Environmental Radiation Monitoring,which currently comprises 60 detector probes for gamma radiation which with a programmable system that includes information technologies, data transmission and software can send the information in real time to a primary center of data located in the facilities of CNSNS. - When the data are received, the system performs the verification and extraction of the information organized in Tables and charts, and generates a report of environmental gamma radiation dose rate average for each of the probes and for each period of time determined bu CNSNS. The RENAMORA covers the main cities and allows to establish the bases of almost the entire country, as well as to warn about abnormal situations caused by incidents or natural events generated by human activities inside or outside the country which involves radioactive materials; paying special attention to main radiological sites, such as the surroundings of the Laguna Verde Nuclear Power Plants, research centers and the radioactive waste disposal sites.

    Full Text Available To date, no direct scientific evidence has been found linking tissue changes in multiple sclerosis (MS patients, such as demyelination, axonal destruction or gliosis, with either steady progression and/or stepwise accumulation of focal CNS lesions. Tissue changes such as reduction of the retinal nerve fiber layer (RNFL and the total macular volume (TMV, or brain- and spinal cord atrophy indicates an irreversible stage of tissue destruction. Whether these changes are found in all MS patients, and if there is a correlation with clinical disease state, remains controversial. The objective of our study was to determine, whether there was any correlation between the RNFL or TMV of patients with MS, and: (1 the lesion load along the visual pathways, (2 the ratios and absolute concentrations of metabolites in the normal-appearing white matter (NAWM, (3 standard brain atrophy indices, (4 disease activity or (5 disease duration.28 MS patients (RRMS, n = 23; secondary progressive MS (SPMS, n = 5 with moderately-high disease activity or long disease course were included in the study. We utilised: (1 magnetic resonance imaging (MRI and (2 -spectroscopy (MRS, both operating at 3 Tesla, and (3 high-resolution spectral domain-OCT with locked reference images and eye tracking mode to undertake the study.There was no consistency in the pattern of CNS metabolites, brain atrophy indices and the RNFL/TMV between individuals, which ranged from normal to markedly-reduced levels. Furthermore, there was no strict correlation between CNS metabolites, lesions along the visual pathways, atrophy indices, RNFL, TMV, disease duration or disability.Based on the findings of this study, we recommend that the concept of 'clinico-radiologico paradox' in multiple sclerosis be extended to CROP-'clinico-radiologico-ophthalmological paradox'. Furthermore, OCT data of MS patients should be interpreted with caution.

    The purpose of this study was to investigate younger (n = 52, ages 18-24) and older (n = 69, ages 61-98) adults' responses to patronizing communication in terms of (a) performance on a cognitive task (Weschler Adult Intelligence Scale-III block design) and (b) physiological responses (i.e., change in cortisol levels), as well as factors that may attenuate those responses. Participants were randomly assigned to receive instructions for the task using either a patronizing or nonpatronizing speech style. Participants also completed a measure of attitudes about aging and the quantity/quality of their intergenerational interaction. Older adults (relative to younger adults) were found to be more reactive to the patronizing speech style in terms of their performance on the task as well as the change in their cortisol levels. Older adults who had more positive attitudes about aging as well as more positive intergenerational interactions were protected from the performance deficits as a result of patronizing speech style. These findings could be used to inform social programs aimed at reducing age-based stigma and improving the life course outcomes of our aging population.

    Full Text Available Timothy Williamson supports the thesis that every possible entity necessarily exists and so he needs to explain how a possible son of Wittgenstein’s, for example, exists in our world:he exists as a merely possible object (MPO, a pure locus of potential. Williamson presents a short argument for the existence of MPOs: how many knives can be made by fitting together two blades and two handles? Four: at the most two are concrete objects, the others being merely possible knives and merely possible objects. This paper defends the idea that one can avoid reference and ontological commitment to MPOs. My proposal is that MPOs can be dispensed with by using the notion of rules of knife-making. I first present a solution according to which we count lists of instructions - selected by the rules - describing physical combinations between components. This account, however, has its own difficulties and I eventually suggest that one can find a way out by admitting possible worlds, entities which are more commonly accepted - at least by philosophers - than MPOs. I maintain that, in answering Williamson’s questions, we count classes of physically possible worlds in which the same instance of a general rule is applied.

  1. Small proportions of actively-smoking patrons and high PM2.5 levels in southern California tribal casinos: support for smoking bans or designated smoking areas

    Klepeis Neil E

    2012-09-01

    Full Text Available Abstract Background Nearly all California casinos currently allow smoking, which leads to potentially high patron exposure to secondhand tobacco smoke pollutants. Some argue that smoking restrictions or bans would result in a business drop, assuming > 50% of patrons smoke. Evidence in Nevada and responses from the 2008 California tobacco survey refute this assertion. The present study investigates the proportion of active smokers in southern California tribal casinos, as well as occupancy and PM2.5 levels in smoking and nonsmoking sections. Methods We measured active-smoker and total-patron counts during Friday or Saturday night visits (two per casino to smoking and nonsmoking gaming areas inside 11 southern California casinos. We counted slot machines and table games in each section, deriving theoretical maximum capacities and occupancy rates. We also measured PM2.5 concentrations (or used published levels in both nonsmoking and smoking areas. Results Excluding one casino visit with extremely high occupancy, we counted 24,970 patrons during 21 casino visits of whom 1,737 were actively smoking, for an overall active- smoker proportion of 7.0% and a small range of ~5% across casino visits (minimum of 5% and maximum of 10%. The differences in mean inter-casino active-smoker proportions were not statistically significant. Derived occupancy rates were 24% to 215% in the main (low-stakes smoking-allowed slot or table areas. No relationship was found between observed active-smoker proportions and occupancy rate. The derived maximum capacities of nonsmoking areas were 1% to 29% of the overall casino capacity (most under 10% and their observed occupancies were 0.1 to over 3 times that of the main smoking-allowed casino areas. Seven of twelve visits to nonsmoking areas with no separation had occupancy rates greater than main smoking areas. Unenclosed nonsmoking areas don’t substantially protect occupants from PM2.5 exposure. Nonsmoking areas

    The increased survival of acquired immunodeficiency syndrome (AIDS) patients achieved through continuous therapeutic advances has led to the onset of new disorders associated with the disease, as well as considerable changes in both the incidence and prevalence of those classifically described. The association of AIDS with lung carcinoma is a controversial issue. It develops in young patients with history of smoking. It has no relation to the levels of blood CD4 lymphocyte counts, and is not diagnosed until very advanced stages, resulting in a mean survival of 10 months. The histological features most frequently correspond to those of adenocarcinoma; its is generally poorly differentiated, with a high replication rate. Knowledge of these facts is indispensable for the radiologist since lung carcinoma should be included in the differential diagnosis in any case in which a fast-growing lung mass is detected. This helps to orient the clinical measures, preventing diagnostic delays, with the consequent impact on the disease course and prognosis. We present four cases of lung carcinoma in patients with human immunodeficiency virus (HIV) infection. The histological diagnosis was adenocarcinoma in two cases (mucinous adenocarcinoma in one of them), giant cell tumor in one and epidermoid carcinoma in the remaining patient. The plain radiographic and computed tomography findings are described and compared with those reported in the literature. (Author) 21 refs.

    This work is carried out in Veracruz State covering over 11 jurisdictions of the State (Panuco, Tuxpan, Poza Rica, Martinez de la Torre, Xalapa, Cordoba, Orizaba, Veracruz, Cosamaloapan, San Andres Tuxtla and Coatzacoalcos). The sampling was realized in a period from 2009 to 2013 analyzing home drinking water, supply sources and wells, the sampling was done by the sanitary checkers of different jurisdictions with approved methods and the methodology was validated at the State Laboratory of Public Health. 1637 samples were analyzed by counting equipment Tennelec Canberra series 5 and a gas supply system P-10 with calibration curves for alpha and gross beta. The results of measurements ranging from 0.07 to 0.25 Bq/L in the activity concentration gross alpha annual average, an gross beta were from 0.12 to 0.17 Bq/L in the activity concentration gross beta annual average, and with a concentration range of alpha activity up to 0.62 and a minimum 0.02, and the concentration of beta activity of a maximum value 1.54 and a minimum 0.02, taking also as resulted in five years of analysis only 1.16% of the analyzed samples (19 samples) showed a value of alpha activity concentration above the minimum detectable concentration and 62.43% (1022 samples) of the analyzed samples showed a value of beta activity concentration above the minimum detectable concentration, is also clear that the results of the sanitary jurisdictions of Panuco and Tuxpan not have corresponding activity values for the years 2009, 2011-2013 except 2010. We can conclude that the regular measurements of alpha and gross beta activity in water are invaluable for timely detection of radioactive contamination. (Author)

    Full Text Available Existen situaciones y comportamientos de la persona, familia y colectivos, que por diferentes circunstancias pueden propiciar la Violencia Intrafamiliar conllevando al Maltrato Infantil. El que se presenten estos factores predispone a la aparicion del maltrato, pero esto no significa que necesariamente el resultado de tales comportamientos desemboque en violencia contra los miembros del nucleo familiar, pero si es seguro que esas personas son mas vulnerables al problema. Cuando la persona traduce el castigo fisico como practica educativa, la primera consecuencia es la asociacion del amor con la violencia. El niflo aprende que aquel que mas le ama es tambien aquel que le pega y que tiene derecho a hacerlo, paradojica negativa para el futuro de ese niflo/a que lleva una vision generalizada para sus proximas relaciones como la de esposo/a, o padres, o hijo/a. Para evitar llegar a lo anterior se deben usar las costumbres beneficas que se transmiten de generaci6n en generaci6n como parte del patron cultural, que tienen que ver como los padres, crian, cuidan y educan a sus hijos, dependen de lo aprendido, de lo vivido y la influencia cultural que se ejerce en cads una de las generaciones, llamadas pautas o Patrones de Crianza, que en conjunto se convierten en una garantia para los mas vulnerables: los niflos/as.

    2016-11-01

    Full Text Available Patrons of public libraries are more diverse and complex than those of other types of libraries, implying potentially more unexpected and difficult situations. Negative emotions such as frustration and anxiety are generated among librarians when they must handle problem patrons, an effort that may influence the work efficiency of librarians and their physical and mental health. This study conducted a semi-structured in-depth interview, using public service librarians in Taiwan as subjects, to explore the categories of problem patrons and their behavioral characteristics. According to the results, the behavioral characteristics of problem patrons can be divided into 6 categories: interfering with others, violating library regulations, influencing library works, improperly using resources and facilities, breaking laws, and exhibiting a psychological disorder as well as violating social norms. On the basis of the research results, this study offers suggestions for future reference when public libraries must handle problem patrons.

  11. [Patron saints and Christian perception of health and illness].

    Science.gov (United States)

    Spehar, Milan

    2012-01-01

    As a religion based on the teaching of Jesus Christ, from the outset Christianity has developed a completely different attitude toward health and illness than the Old Testament. Health and illness are now viewed through the eyes of Jesus Christ the redeemer, who accepted each and every man. The history of Christianity has had its episodes of masochistic attitude toward illness, but today it clearly underscores the need to fight it with any means available, but it also teaches to accept what can not be changed. Saints are often patrons against diseases they had to endure. However, this is not their main role. To this day many seem to miss the main point their heritage, but see them as miracle healers. This misperception of miracle needs revising as well as the simplistic interpretation of the healing powers of relics (viewed as a demiurge of sort) and of the private vows and votive offerings.

    Restaurant initiatives provide an efficient opportunity to impact large numbers of patrons. The purpose of this study is to measure patron purchasing behaviors during the ¡Por Vida! menu designation initiative. This study used a cross-sectional design and survey data to assess 23 restaurants throughout Bexar County and 152 restaurant patrons. The Patron Awareness Questionnaire assessed if patrons noticed the logo; believed nutrition, cost, and taste were important in making purchasing decisions; and purchased a ¡Por Vida! item. Descriptive statistics, Spearman correlations, and logistic regression were used to analyze the data. Most (93.4%) patrons considered taste very important when deciding what to eat. Cost was very important to 63.8% and nutrition was very important to 55.9% of the sample. The strongest predictors of purchasing a ¡Por Vida! item were the patrons' ages being between 18 and 35 years (odds ratio = 1.474; confidence interval = 0.017, 0.812; p segment of the population when the logo is visible.

    2016-01-01

    This study provides economically disadvantaged, minority food pantry patrons (hereafter, patrons) a meaning-ful voice by examining their experiences trying to obtain sufficient, nutritious food. Five focus groups were conducted using a semistructured discussion guide. Atlast.ti software was used to manage and analyze the data. Patrons reported that pantry staff who preserved their dignity by showing compassion were highly valued. Stigma and shame associated with pantry use were major concerns. Patrons suggested environmental and policy changes to improve their food acquisition experiences. These findings suggest that multilevel interventions addressing food access, food distribution policies, and patron-staff interactions are warranted.

    Full Text Available Building on Arizona State University's patron-driven acquisitions (PDA initiative in 2009, the Arizona Universities Library Consortium, in partnership with the Ingram Content Group, created a cooperative patron-driven model to acquire electronic books (e-books. The model provides the opportunity for faculty and students at the universities governed by the Arizona Board of Regents (ABOR to access a core of e-books made accessible through resource discovery services and online catalogs. These books are available for significantly less than a single ABOR university would expend for the same materials. The patron-driven model described is one of many evolving models in digital scholarship, and, although the Arizona Universities Library Consortium reports a successful experience, patron-driven models pose questions to stakeholders in the academic publishing industry.

    Alcohol sales to intoxicated patrons are illegal and may lead to public health issues such as traffic crashes and violence. Over the past several decades, considerable effort has been made to reduce alcohol sales to underage persons but less attention has been given to the issue of sales to obviously intoxicated patrons. Studies have found a high likelihood of sales to obviously intoxicated patrons (i.e., overservice), but little is known about efforts by enforcement agencies to reduce these sales. We conducted a survey of statewide alcohol enforcement agencies and local law enforcement agencies across the US to assess their strategies for enforcing laws prohibiting alcohol sales to intoxicated patrons at licensed alcohol establishments. We randomly sampled 1,631 local agencies (1,082 participated), and surveyed all 49 statewide agencies that conduct alcohol enforcement. Sales to obviously intoxicated patrons were reported to be somewhat or very common in their jurisdiction by 55 % of local agencies and 90 % of state agencies. Twenty percent of local and 60 % of state agencies reported conducting enforcement efforts to reduce sales to obviously intoxicated patrons in the past year. Among these agencies, fewer than half used specific enforcement strategies on at least a monthly basis to prevent overservice of alcohol. Among local agencies, enforcement efforts were more common among agencies that had a full-time officer specifically assigned to carry out alcohol enforcement efforts. Enforcement of laws prohibiting alcohol sales to obviously intoxicated patrons is an underutilized strategy to reduce alcohol-related problems, especially among local law enforcement agencies.

    Brazil has a strict drinking and driving law known as the Brazilian "Dry Law". The aim of the present study was to investigate characteristics associated with the breaking of the Brazilian traffic law, on drinking and driving, at nightclub exit among a representative sample of nightclub patrons in the city of São Paulo, Brazil. Portal survey realized with a two-stage cluster sampling survey design to collect data from 2422 patrons at the entrance and 1822 patrons at the exit of 31 nightclubs in the city of São Paulo, Brazil. Patrons' breath alcohol concentrations (BrACs) at the entrance and exit of the nightclubs were categorized according to the law as either a "traffic offense" or a "traffic offense and crime". Weighted multinomial logistic regression was used to analyze factors associated with different patterns of drinking and driving offenses. Of the subjects, 16.5% (n=369) were identified as driving patrons at the entrance and exit of the nightclubs. At entry, 80.1% of the patrons had a zero BrAC, 14.9% had a BrAC meeting the traffic offense criteria and 5.0% had a BrAC meeting the traffic offense and crime criteria. Women were less likely to have BrACs meeting the traffic offense criteria. At nightclub exit, 63.4% of patrons had maintained a zero BrAC, 24.7% had a BrAC that had increased and now met the traffic offense and crime criteria, and 11.9% had a decreased or stable BrAC. An increased BrAC was more frequently identified in patrons who were men, were single, and had used illicit drugs inside the nightclub. Despite the existence of a strict law regarding drinking and driving, a significant proportion of nightclub patrons in the city of São Paulo had violated this law, suggesting a perception of impunity and need for law enforcement.

    Full Text Available Techniques that analyze biological remains from sediment sequences for environmental reconstructions are well established and widely used. Yet, identifying, counting, and recording biological evidence such as pollen grains remain a highly skilled, demanding, and time-consuming task. Standard procedure requires the classification and recording of between 300 and 500 pollen grains from each representative sample. Recording the data from a pollen count requires significant effort and focused resources from the palynologist. However, when an adaptation to the recording procedure is utilized, efficiency and time economy improve. We describe EcoCount, which represents a development in environmental data recording procedure. EcoCount is a voice activated fully customizable digital count sheet that allows the investigator to continuously interact with a field of view during the data recording. Continuous viewing allows the palynologist the opportunity to remain engaged with the essential task, identification, for longer, making pollen counting more efficient and economical. EcoCount is a versatile software package that can be used to record a variety of environmental evidence and can be installed onto different computer platforms, making the adoption by users and laboratories simple and inexpensive. The user-friendly format of EcoCount allows any novice to be competent and functional in a very short time.

    Objectives. We compared exposure to secondhand smoke (SHS) and attitudes toward smoke-free bar and nightclub policies among patrons of lesbian, gay, bisexual, and transgender (LGBT) and non-LGBT bars and nightclubs. Methods. We conducted randomized time–location sampling surveys of young adults (aged 21–30 years) in 7 LGBT (n = 1113 patrons) and 12 non-LGBT (n = 1068 patrons) venues in Las Vegas, Nevada, in 2011, as part of a cross-sectional study of a social branding intervention to promote a tobacco-free lifestyle and environment in bars and nightclubs. Results. Compared with non-LGBT bars and nightclubs, patrons of LGBT venues had 38% higher adjusted odds of having been exposed to SHS in a bar or nightclub in the past 7 days but were no less likely to support smoke-free policies and intended to go out at least as frequently if a smoke-free bar and nightclub law was passed. Conclusions. The policy environment in LGBT bars and nightclubs appears favorable for the enactment of smoke-free policies, which would protect patrons from SHS and promote a smoke-free social norm.

    Full Text Available BACKGROUND: Prior research suggests that arrest, compared with no police detection, of some types of offenders does not decrease the chances they will reoffend. METHODOLOGY/PRINCIPAL FINDINGS: We assessed the specific deterrent effect of arrest for patronizing a street prostitute in Colorado Springs by comparing the incidence of arrest for clients of prostitutes first detected through public health surveillance with the incidence of rearrest for clients first detected by police arrest. Although these sets of clients were demographically and behaviorally similar, arrest reduced the likelihood of a subsequent arrest by approximately 70%. In other areas of the United States, arrest did not appear to displace a client's patronizing. CONCLUSIONS/SIGNIFICANCE: Our results suggest that apprehending clients decreases their patronizing behavior substantially.

    2010-01-01

    Abelian orbifolds of C^3 are known to be encoded by hexagonal brane tilings. To date it is not known how to count all such orbifolds. We fill this gap by employing number theoretic techniques from crystallography, and by making use of Polya's Enumeration Theorem. The results turn out to be beautifully encoded in terms of partition functions and Dirichlet Series. The same methods apply to counting orbifolds of any toric non-compact Calabi-Yau singularity. As additional examples, we count the orbifolds of the conifold, of the L^{aba} theories, and of C^4.

    Full Text Available El trabajo se realizó en la Estación Experimental Los Diamantes del INTA entre el 2004 y el 2007, con el objetivo de determinar el efecto de varios patrones en la injertación de la guayaba. Se evaluaron cuatro patrones: tres de cas (Psidium friedrichsthalianum, y uno de guayaba, sobre el crecimiento y desarrollo de un clon experimental de guayaba (Psidium guajava. En la etapa de vivero, el prendimiento fue de un 100% para los patrones guayaba y "cas brasileño", mientras que para los tratamientos con "arrayán" y "cas criollo" fue de un 90%. El crecimiento vegetativo inicial fue significativamente mayor en el testigo. En el campo, se observó la misma tendencia de mayor crecimiento en el tratamiento de guayaba como patrón. También, se observó un claro efecto enanizante del patrón arrayán, mientras que los patrones "cas brasileño" y "cas criollo" mostraron un crecimiento intermedio. El número y peso de la fruta fue superior en el tratamiento de guayaba como patrón y no hubo diferencias entre los tipos de cas. Con el fin de evaluar la susceptibilidad de los patrones a nematodos en plantas adultas, se incluyó un testigo adicional de guayaba al que se le aplicó nematicida en campo. Los resultados indican que los nematodos Meloidogyne sp. y Pratylenchus sp. lograron colonizar las raíces de los tratamientos de guayaba con y sin nematicida, así como del cas brasileño. No se detectaron nematodos en las raíces de los patrones cas criollo ni de arrayán.

    For those suffering from breast cancer, Agatha is their patron saint. She was a beautiful Christian maiden, from Catania, Sicily, who dedicated her life to God. As she rejected the love proposals of consul Quintiliano, she suffered cruel tortures. One of the tortures she suffered was to have her breast cut off, with iron shears, a detail that furnished to the Christian medieval iconography, the peculiar characteristic of Agatha. Catania honors Agatha as her patron saint and throughout the region around Mt. Etna. Saint Agatha's feast day is February 5. All of those dedicated to the treatment and prevention of breast cancer are known as "the soldiers of Saint Agatha".

    2009-09-01

    Full Text Available This article presents a social-scientific interpretation of the parable of the rich man and Lazarus. Attention is first given to the history of the interpretation of the parable and to the integrity and authenticity of this interpretation. A social-scientific reading of the parable is then presented in terms of the strategy and the situation of the parable. In terms of the latter, the parable is read against the backdrop of an advanced agrarian (aristocratic society in which patronage and clientism played an important role. Regarding the parable’s strategy, it is argued that the different oppositions in the parable serve to highlight their only similarity: those who have the ability to help do not help. The gist of the parable is that patrons who do not act like patrons create a society wherein a chasm so great between rich and poor is brought into existence that it cannot be crossed.

  5. Counting Belief Propagation

    CERN Document Server

    Kersting, Kristian; Natarajan, Sriraam

    2012-01-01

    A major benefit of graphical models is that most knowledge is captured in the model structure. Many models, however, produce inference problems with a lot of symmetries not reflected in the graphical structure and hence not exploitable by efficient inference techniques such as belief propagation (BP). In this paper, we present a new and simple BP algorithm, called counting BP, that exploits such additional symmetries. Starting from a given factor graph, counting BP first constructs a compressed factor graph of clusternodes and clusterfactors, corresponding to sets of nodes and factors that are indistinguishable given the evidence. Then it runs a modified BP algorithm on the compressed graph that is equivalent to running BP on the original factor graph. Our experiments show that counting BP is applicable to a variety of important AI tasks such as (dynamic) relational models and boolean model counting, and that significant efficiency gains are obtainable, often by orders of magnitude.

  6. Analog multivariate counting analyzers

    Nikitin, A V; Armstrong, T P

    2003-01-01

    Characterizing rates of occurrence of various features of a signal is of great importance in numerous types of physical measurements. Such signal features can be defined as certain discrete coincidence events, e.g. crossings of a signal with a given threshold, or occurrence of extrema of a certain amplitude. We describe measuring rates of such events by means of analog multivariate counting analyzers. Given a continuous scalar or multicomponent (vector) input signal, an analog counting analyzer outputs a continuous signal with the instantaneous magnitude equal to the rate of occurrence of certain coincidence events. The analog nature of the proposed analyzers allows us to reformulate many problems of the traditional counting measurements, and cast them in a form which is readily addressed by methods of differential calculus rather than by algebraic or logical means of digital signal processing. Analog counting analyzers can be easily implemented in discrete or integrated electronic circuits, do not suffer fro...

  13. Neutron counting with cameras

    Energy Technology Data Exchange (ETDEWEB)

    Van Esch, Patrick; Crisanti, Marta; Mutti, Paolo [Institut Laue Langevin, Grenoble (France)

    2015-07-01

    A research project is presented in which we aim at counting individual neutrons with CCD-like cameras. We explore theoretically a technique that allows us to use imaging detectors as counting detectors at lower counting rates, and transits smoothly to continuous imaging at higher counting rates. As such, the hope is to combine the good background rejection properties of standard neutron counting detectors with the absence of dead time of integrating neutron imaging cameras as well as their very good spatial resolution. Compared to Xray detection, the essence of thermal neutron detection is the nuclear conversion reaction. The released energies involved are of the order of a few MeV, while X-ray detection releases energies of the order of the photon energy, which is in the 10 KeV range. Thanks to advances in camera technology which have resulted in increased quantum efficiency, lower noise, as well as increased frame rate up to 100 fps for CMOS-type cameras, this more than 100-fold higher available detection energy implies that the individual neutron detection light signal can be significantly above the noise level, as such allowing for discrimination and individual counting, which is hard to achieve with X-rays. The time scale of CMOS-type cameras doesn't allow one to consider time-of-flight measurements, but kinetic experiments in the 10 ms range are possible. The theory is next confronted to the first experimental results. (authors)

    The circulating blood volume accounts for 8% of the body weight, of which 45% comprises cellular components (blood cells) and 55% liquid components. We can measure the number and morphological features of blood cells (leukocytes, red blood cells, platelets), or count the amount of hemoglobin in a complete blood count: (CBC). Blood counts are often used to detect inflammatory diseases such as infection, anemia, a bleeding tendency, and abnormal cell screening of blood disease. This count is widely used as a basic data item of health examination. In recent years, clinical tests before consultation have become common among outpatient clinics, and the influence of laboratory values on consultation has grown. CBC, which is intended to count the number of raw cells and to check morphological features, is easily influenced by the environment, techniques, etc., during specimen collection procedures and transportation. Therefore, special attention is necessary to read laboratory data. Providing correct test values that accurately reflect a patient's condition from the laboratory to clinical side is crucial. Inappropriate medical treatment caused by erroneous values resulting from altered specimens should be avoided. In order to provide correct test values, the daily management of devices is a matter of course, and comprehending data variables and positively providing information to the clinical side are important. In this chapter, concerning sampling collection, blood collection tubes, dealing with specimens, transportation, and storage, I will discuss their effects on CBC, along with management or handling methods.

    2016-05-01

    Digital holography uses electronic sensors for hologram recording and numerical method for hologram reconstruction enabling thus the development of advanced holography applications. However, in some cases, the useful information is concealed in a very wide dynamic range of illumination intensities and successful recording requires an appropriate dynamic range of the sensor. An effective solution to this problem is the use of a photon-counting detector. Such detectors possess counting rates of the order of tens to hundreds of millions counts per second, but conditions of recording holograms have to be investigated in greater detail. Here, we summarize our main findings on this problem. First, conditions for optimum recording of digital holograms for detecting a signal significantly below detector's noise are analyzed in terms of the most important holographic measures. Second, for time-averaged digital holograms, optimum recordings were investigated for exposures shorter than the vibration cycle. In both cases, these conditions are studied by simulations and experiments.

  8. What Counts as Prostitution?

    Full Text Available What counts, or should count, as prostitution? In the criminal law today, prostitution is understood to involve the provision of sexual services in exchange for money or other benefits. But what exactly is a ‘sexual service’? And what exactly is the nature of the required ‘exchange’? The key to answering these questions is to recognize that how we choose to define prostitution will inevitably depend on why we believe one or more aspects of prostitution are wrong or harmful, or should be criminalized or otherwise deterred, in the first place. These judgements, in turn, will often depend on an assessment of the contested empirical evidence on which they rest. This article describes a variety of real-world contexts in which the ‘what counts as prostitution’ question has arisen, surveys a range of leading rationales for deterring prostitution, and demonstrates how the answer to the definition question depends on the answer to the normative question. The article concludes with some preliminary thoughts on how analogous questions about what should count as sexual conduct arise in the context of consensual offences such as adultery and incest, as well as non-consensual offences such as sexual assault.

The study one carries out with 35 students (Odontologists), 7 men and 28 women, with ages between 20 and 24 years. A characterization of risk was made following the methodology of the Agency for the environmental control of United States (EPA), counting the number of shots in each list, during the time of training. The effective energy of the X rays used was of 24 KeV. The irradiation technique understood two modalities; the first one with 3 shots of 1.25 seconds and the second with 5 shots of 0.6 seconds. The measurement of E, was carried out with thermoluminescent dosemeters (TL) of LiF:Mg,Cu,P+PTFE, developed in the National Institute of Nuclear Research (ININ). The homogenization of the dosemeters showed a variation in its response to the radiation of 1.85%DS. For the odontologist position, the dosemeters was placed to the height of the chest and the measurement was multiplied by the number of shots that it was 304. The E value was of 3.62 mSv/four-month (11 mSv/year), without any safety equipment and of 2.02 mSv/four-month (6.14 mSv/year), when was considered the scenario for this position with use of vest and lead collar, like safety equipment, diminishing E, almost 50%. In the case of the corresponding position to patient, E, it was measured in different organs of interest, the obtained results are compared with the international standards.

    Reference departments track patron interactions to illustrate the type and number of services provided as well as to tailor librarians' time and expertise to the interest and needs of their patrons. Until 2010 the Reference, Education, and Community Engagement Department at the Calder Memorial Library tracked statistics using a complicated system of paper tic sheets and two Excel™ spreadsheets. After considering different electronic systems, the department decided to employ an electronic form created with SurveyMonkey™ to track patron interactions. After the system had been in place for three months, the authors administered a satisfaction and use survey to collect faculty and staff feedback on the new system. Seven months later the authors undertook usability testing to collect further evaluative data on the electronic form. The patron interaction form continues to be used to collect statistics, provide data for annual reviews, and recognize the contributions of all faculty and staff at the library.

    Full Text Available The objective of this article is to study the relation among resource utilization pattern, subsistence and patron client relationship in Danau Tempes fisheries community, South Sulawesi, using a qualitative research method. Data were collected purposive for both small scale and relatively big scale fisheries by means of indepth interview and observation. Scotts moral economy framework was used to analyze the nature of social phenomena. The results show that fisheries resource scarcity due to intensive fishing activities were the reason behind fisheries communitys strategy to handle the subsistence crisis. Patron-client relation was used by fisheries community which hold trust and kinship in regard. The relation was also based on mutual solution in terms of social reciprocity. Clients tend to maintain their relation to patrons due to safety and security reasons from their subsistence crisis, eventhough they have smaller economic profit from that relation. While patrons help clients based on social obligation to help others.

    Full Text Available The murals of Christ`s Transfiguration cathedral in Polotsk (ca. 1161, which were revealed during restoration in the last several years, include several thematic strata. Among them especially notable is a group of images, related to the patron saints. Distinguished among them are the figures of the patron saints of the Polotsk ducal family, to which St. Euphrosynia of Polotsk, the founder of the monastery and the builder of the Christ`s Church, belonged. The composition “Exaltation of the Cross” is set in one row with the patron saints, thus revealing semantic correlation with the ktitors` portrait in Kiev Saint Sophia and some other Kiev churches of tenth and eleventh centuries, where the idea of Russia becoming a member of Christian community is developed. At the same time, the patron theme is deeply intertwined with the purpose of the Christ`s Church to serve as a family burial for St. Euphrosynia.

    Objective: To meet the information needs of isolated primary care providers and their patients in the US Navy, a digital health sciences library, the Virtual Naval Hospital, was created through a unique partnership between academia and government. Methods: The creation of the digital library was heavily influenced by the principles of user-centered design and made allowances for the nomadic nature of the digital library's patrons and the heterogeneous access they have to Internet bandwidth. Results: The result is a digital library that has been in operation since 1997, continues to expand in size, is heavily used, and is highly regarded by its patrons. Conclusions: The digital library is dedicated to delivering the right information at the right time to the right person so the right decision can be made, and therefore the Virtual Naval Hospital functions as a knowledge-management system for the US Navy Bureau of Medicine and Surgery.

    2010-04-01

    The California smokefree workplace ordinance (AB13) has been well-received, even in bars where deeply established traditions of smoking may exist. However, a closer investigation of bars where indoor smoking persists revealed that bar workers in some ethnic minority communities continue to be exposed to secondhand smoke in their workplaces. To identify sociocultural factors that may impede the adoption of AB13, the researchers conducted 150 observations and 29 patron and staff interviews in 50 California bars serving Asian patrons in Los Angeles and San Francisco counties. Observers witnessed indoor smoking in 82% of the bars. Interviews revealed that social relationships, social interactions, and a tendency to avoid confrontation complicated the positive reception of AB13 within these bars. Accounting for sociocultural factors provides a nuanced understanding of the challenges involved in implementing tobacco control policy in such diverse settings and may allow for culturally appropriate tobacco policy development and implementation in other jurisdictions.

    Incidences of violence are elevated in night-time entertainment districts. Research suggests that safety-related behavioural strategies adopted while drinking can reduce negative alcohol-related outcomes. The current study investigates the use of safety strategies and its association with experiences of violence among patrons from the general population. Patron interviews (N = 3949) were conducted in and around licenced venues in Newcastle (New South Wales) and Geelong (Victoria) during peak trading hours (Friday and Saturday, 21:00-01:00 h). Participants (mean age = 24.3, SD = 5.8; male 54.4%) were asked to report what measures, if any, they used to keep safe when drinking and whether they had been involved in a violent incident in the last 12 months. After controlling for patron demographics and location, the use of multiple (more than one) safety strategies was significantly associated with reduced odds of involvement in a violent incident (odds ratio = 0.64, 95% confidence interval 0.49-0.85, P = 0.002). Significant gender differences were observed in the number and type of safety strategies reported. Increasing the number of safety-related behaviours during drinking occasions is associated with a small but significant reduction in experiencing alcohol-related harms, such as violence.

    We make use of the voluntary HIV and syphilis test results conducted at five gay saunas in Taipei from August of 1999 to end of 2002 to estimate the number of HIV-positive gay saunas patrons in Taipei area by utilizing Hierarchical Bayes method in Generalized Removal Model for Open Populations (GERMO). Considering the effect of a nearby anonymous HIV quick test program on the gay sauna HIV serotesting data, we make use of the association between HIV and syphilis serotesting results from the gay sauna program to amend possible measurement error occurred at the time of data collection by utilizing the regression calibration method. The median estimates for the number of HIV-positive patrons of the five gay saunas increase from 120 (95% CI: 76.5-159.0) during the first half of 2000 to 224 (95% CI: 171.0-265.5) for the second half of 2002. The result, indicating two-fold increase within two and half years, confirms that the gay sauna patrons in Taipei area are at high risk for HIV infection.

    The aim of this study was to investigate psychoactive drug use among nightclub patrons by analysing samples of oral fluid and compare with findings in blood samples from criminal suspects. We hypothesized that the profile of illicit drug use among nightclub patrons is different from what we observe in those forensic cases. Research stations were established outside nine popular nightclubs with different profiles and patron-characteristics in downtown Oslo. Data and sample collection was conducted on Fridays and Saturdays in March and May 2014. Individuals and groups who entered defined recruitment zones from 23:00 to 03:30 were invited to participate in this voluntary and anonymous study. Oral fluid was collected using the Intercept Oral Fluid Sampling Device. Methanol was added to increase the recovery of cannabinoids from the device. Sample preparation was performed using liquid-liquid extraction with ethyl acetate/heptane (4:1) after adding internal standards, ammonium carbonate buffer pH 9.3 and Triton X100. The first 80 samples were analysed for 122 substances, which included psychoactive medicinal drugs, classical illicit drugs and new psychoactive substances (NPS). Based on the findings and discussions with police and customs authorities, the remaining oral fluid samples were analysed for 46 substances. Among the 500 samples collected during the study period, we found illicit drugs in 25.4% and medicinal drugs in 4.2% of the samples. The most prevalent substances were: cocaine 14.6%, THC 12.4%, amphetamine/methamphetamine 2.8%, diazepam 1.2% and clonazepam 1.0%. Various NPS were found in 1.4% of the samples. The prevalence of drugs in blood samples from criminal suspects were for cocaine 3.4%, THC 34.7%, amphetamine/methamphetamine 37.0%, diazepam 12.0%, and clonazepam 29.3%. Multi-drug use was more common among criminal suspects (41.3%) than among club patrons (6.8%). The results showed that the drug use pattern among nightclub patrons was substantially

    non completamente risolto per talune condizioni patologiche, nelle quali i dati obiettivi ed anamnestici sono relativamente uniformi e il quadro radiologico privo di qualsiasi caratteristica. Materiale e metodi: Il materiale � costituito da sei casi di istiocitosi delle cellule di Langherans della mandibola osservati nell'arco di un decennio. Lo studio � basato sulla valutazione della documentazione radiologica tradizionale. Le radiografie sono state eseguite in proiezione latero-laterale-obliqua che, come noto, libera quasi completamente la porzione orizzontale della mandibola dalla sovrapposizione delle immagini di altre strutture ossee. Risultati: I risultati delle indagini radiologiche sono riportati nella tabella I. Si tratta di reticoloendoteliopatie capaci di dar luogo ad un processo granulomatoso costituito da polinucleati eosinofili, plasmacellule e linfociti e, fondamentalmente, da grandi cellule istiocitarie mononucleate dotate di attivit� granulopessica e fagocitaria, spiccatamente proliferanti nel tessuto osseo, identificabili con le cellule di Langherhans della pelle, delle mucose, degli spazi periodontali, del midollo osseo. Il tessuto granulomatoso che ne deriva si infiltra tra gli elementi costitutivi dell'organo colpito ed estendendosi comprime, atrofizza e tende a distruggere il tessuto, sostituendosi ad esso. Le alterazioni determinate dal granuloma isiocitario di Langherhans prevalgono nettamente nel sistema scheletrico e si verificano, in ordine di frequenza, nel cranio, nelle ossa lunghe dell'estremit�, nel piede, nelle coste e nella colonna vertebrale. L'interessamento della mucosa orale � eccezionale. Conclusioni: Nel granuloma istiocitario unifocale di Langherhans della mandibola l'indagine radiologica � indispensabile per l'approccio allo studio della tumefazione premandibolare fermo restando che la diagnosi di natura si basa esclusivamente sulla biopsia.

  12. Counting coalescent histories.

    Science.gov (United States)

    Rosenberg, Noah A

    2007-04-01

    Given a species tree and a gene tree, a valid coalescent history is a list of the branches of the species tree on which coalescences in the gene tree take place. I develop a recursion for the number of valid coalescent histories that exist for an arbitrary gene tree/species tree pair, when one gene lineage is studied per species. The result is obtained by defining a concept of m-extended coalescent histories, enumerating and counting these histories, and taking the special case of m = 1. As a sum over valid coalescent histories appears in a formula for the probability that a random gene tree evolving along the branches of a fixed species tree has a specified labeled topology, the enumeration of valid coalescent histories can considerably reduce the effort required for evaluating this formula.

  13. Oscillations in counting statistics

    CERN Document Server

    Wilk, Grzegorz

    2016-01-01

    The very large transverse momenta and large multiplicities available in present LHC experiments on pp collisions allow a much closer look at the corresponding distributions. Some time ago we discussed a possible physical meaning of apparent log-periodic oscillations showing up in p_T distributions (suggesting that the exponent of the observed power-like behavior is complex). In this talk we concentrate on another example of oscillations, this time connected with multiplicity distributions P(N). We argue that some combinations of the experimentally measured values of P(N) (satisfying the recurrence relations used in the description of cascade-stochastic processes in quantum optics) exhibit distinct oscillatory behavior, not observed in the usual Negative Binomial Distributions used to fit data. These oscillations provide yet another example of oscillations seen in counting statistics in many different, apparently very disparate branches of physics further demonstrating the universality of this phenomenon.

    A comparison was made of 72 men who were patrons in hotels with 6 A.M. or 7 A.M. opening, with a control group of 87 men interviewed in nearby hotels with 10 A.M. opening. The two groups were very similar on biographical characteristics, yet the men in the early-opening group consumed significantly more alcohol, had more drinking sessions, spent longer in drinking, and had significantly higher SMAST scores. The early opening was apparently facilitating problem drinking.

    We study the counts of resolved SZE (Sunyaev-Zel'dovich effect) clus-ters expected from an interferometric survey in different cosmological models underdifferent conditions. The self-similar universal gas model and Press-Schechter massfunction are used. We take the observing frequency to be 90 GHz, and consider twodish diameters, 1.2 m and 2.5 m. We calculate the number density of the galaxyclusters dN/(dΩdz) at a high flux limit Slimv = 100mJy and at a relative lowSlimv = 10 mJy. The total numbers of SZE clusters N in two low-Ω0 models arecompared. The results show that the influence of the resolved effect depends notonly on D, but also on Slimv: at a given D, the effect is more significant for a highthan for a low Slim Also, the resolved effect for a flat universe is more impressivethan that for an open universe. For D = 1.2m and Slimv= 10mJy, the resolvedeffect is very weak. Considering the designed interferometers which will be used tosurvey SZE clusters, we find that the resolved effect is insignificant when estimatingthe expected yield of the SZE cluster surveys.

    Let $K$ be a field, complete with respect to a discrete non-archimedian valuation and let $k$ be the residue field. Consider a system $F$ of $n$ polynomial equations in $K\\vars$. Our first result is a reformulation of the classical Hensel's Lemma in the language of tropical geometry: we show sufficient conditions (semiregularity at $w$) that guarantee that the first digit map $\\delta:(K^\\ast)^n\\to(k^\\ast)^n$ is a one to one correspondence between the solutions of $F$ in $(K^\\ast)^n$ with valuation $w$ and the solutions in $(k^\\ast)^n$ of the initial form system ${\\rm in}_w(F)$. Using this result, we provide an explicit formula for the number of solutions in $(K^\\ast)^n$ of a certain class of systems of polynomial equations (called regular), characterized by having finite tropical prevariety, by having initial forms consisting only of binomials, and by being semiregular at any point in the tropical prevariety. Finally, as a consequence of the root counting formula, we obtain the expected number of roots in $(K...

    The arc of reception for a new technology or method--like the reception of new information itself--can pass through predictable stages, with audiences' responses evolving from 'I don't believe it', through 'well, maybe' to 'yes, everyone knows that' to, finally, 'old news'. The idea that one can sample a volume of water, sequence DNA out of it, and report what species are living nearby has experienced roughly this series of responses among biologists, beginning with the microbial biologists who developed genetic techniques to reveal the unseen microbiome. 'Macrobial' biologists and ecologists--those accustomed to dealing with species they can see and count--have been slower to adopt such molecular survey techniques, in part because of the uncertain relationship between the number of recovered DNA sequences and the abundance of whole organisms in the sampled environment. In this issue of Molecular Ecology Resources, Evans et al. (2015) quantify this relationship for a suite of nine vertebrate species consisting of eight fish and one amphibian. Having detected all of the species present with a molecular toolbox of six primer sets, they consistently find DNA abundances are associated with species' biomasses. The strength and slope of this association vary for each species and each primer set--further evidence that there is no universal parameter linking recovered DNA to species abundance--but Evans and colleagues take a significant step towards being able to answer the next question audiences tend to ask: 'Yes, but how many are there?'

    2007-02-01

    In August-September 2004, a cryptosporidiosis outbreak affected >250 persons who visited a California waterpark. Employees and patrons of the waterpark were affected, and three employees and 16 patrons admitted to going into recreational water while ill with diarrhoea. The median illness onset date for waterpark employees was 8 days earlier than that for patrons. A case-control study determined that getting water in one's mouth on the waterpark's waterslides was associated with illness (adjusted odds ratio 7.4, 95% confidence interval 1.7-32.2). Laboratory studies identified Cryptosporidium oocysts in sand and backwash from the waterslides' filter, and environmental investigations uncovered inadequate water-quality record keeping and a design flaw in one of the filtration systems. Occurring more than a decade after the first reported outbreaks of cryptosporidiosis in swimming pools, this outbreak demonstrates that messages about healthy swimming practices have not been adopted by pool operators and the public.

    Full Text Available Food and alcohol are the key elements of celebrating a Mexican fiesta. I show that drinking at patronal feasts can be the way of constructing a respectful position, as presented in the ethnographic material collected in the three suburban communities of the Central Valleys of Oaxaca (in the years 2012–13. I discuss the relation between drinking alcohol at fiestas, participation and collective identity. I analyse the issue of prestige in the context drinking at fiestas and its relation to gender. I also discuss the role of alcohol in ritual exchanging of gifts at the patronal feasts which were under study and its relation with prestige. Other questions being analysed include the problem of refusing drink and the Catholic and non-Catholic critiques of patronal feasts as based on perceptions of excessive drinking.

    Community pharmacies vary widely in terms of ownership structures, location, and dispensing policies. It is unknown if an association exists between the type of community pharmacy and the degree of medication adherence exhibited by patrons-patients. To describe adherence to statin therapy among subjects patronizing different types of community pharmacy categories (department- mass merchandise, chain-franchise, and independent-banner) in Saskatchewan, Canada, between 2000 and 2005. Study data were obtained from the Saskatchewan Drug Plan and Extended Benefits database, which is maintained by the government of Saskatchewan, Canada. The study included all subjects who (a) filled a statin prescription within selected community pharmacies between January 1, 2000, and December 31, 2005; (b) had no record of statin prescriptions during the year prior to the first statin prescription, according to the records of the Saskatchewan Drug Plan and Extended Benefits; and (c) demonstrated active utilization in the drug plan database for at least 1 year after the first statin prescription. The proxy criterion for activity was any dispensing record for statin or nonstatin medications at least 1 year following the index claim. Statin adherence level was estimated as tablets per day, defined as the total number of tablets dispensed divided by the total number of days of observation. Each subject's observation period began on the index date and ended on the earlier of (a) 30 days after the last recorded fill for any type of prescription medication (statin or nonstatin), or (b) December 31, 2005. The primary end point was the proportion of subjects within each pharmacy category who maintained an adherence level of 80% or greater during their individual observation period. Additional adherence calculations were performed for each of 3 time periods, beginning on the index date and ending on days 365, 729, and 1094 (i.e., 1, 2, and 3 years).

The Beck Depression Inventory, the Liebowitz Social Anxiety Scale (LSAS, the Adult Attention Deficit Disorder/Attention Deficit and Hyperactivity Disorder (ADD/ADHD Scale and the Michigan Alcoholism Screening Test (MAST were administered to the participants. Results: One fourth of the participants (25.4% were under high risk for a depressive episode (BDI>17, 22 (32.3% reported significant social anxiety (LSAS>30, and 41 (57.7% showed moderate ADHD symptoms (Adult ADD/ADHD scale: 20-59. According to BDI score participants who were under the risk for depression showed higher scores in Adult ADD/ADHD scale scores than that of participants who were not under a risk for depression (p=0.001 for attention deficit; p=0.003 for hyperactivity; p=0.002 for impulsivity; p=0.001 for total score. In the study group, ADD/ADHD scale attention deficit score was positively correlated with the total fear, total avoidence and the total scores of LSAS (r=.359 p<0.01; r=.332 p<0.01; r=.358 p<0.01, respectively. Conclusion: Heavy metal bar patrons appear to be a particular social group with an increased risk of psychopathology.

    Full Text Available En este trabajo se aplican y se extienden los patrones de evolución de filiales planteados por Birkinshaw y Hood, al estudiar la influencia de los entornos volátiles sobre los procesos de evolución de las filiales de empresas multinacionales. Utilizando una metodología cualitativa a través de 41 estudios de casos de filiales de diversos sectores localizadas en Venezuela, se observó que las mismas siguen procesos conducentes a la mejora, el refuerzo y al declive de sus roles. En los resultados se identifican a la matriz y la propia filial como impulsores de esos procesos, pero se aprecia también al entorno local como determinante de la evolución de las filiales, con lo cual se extienden los patrones que plantean Birkinshaw y Hood que consideran sólo a la matriz y a la propia filial. Como conclusión, no sólo se resalta la importancia del entorno en la determinación del rol de las filiales, sino que se evidencia que los entornos volátiles pueden tener un impacto tanto positivo como negativo en la evolución de la filial.

    Full Text Available College students are accessing virtual libraries whether they are on campus or learning from a distance. Academic institutions serving virtual patrons must remain focused on meeting the needs of those library users by continually examining their preferences, their searching behavior, and the information they seek. The purpose of this research was to determine if virtual patrons are satisfied with the resources and services being provided by a university’s online library. Following a web-based survey, demographic characteristics of students were analyzed to determine if any influenced students’ satisfaction. Using analysis of variance, correlation, and descriptive statistics, several demographic factors were found to influence student satisfaction with the library’s online resources: age, gender, achieved educational level, student status, and computer experience. One factor, computer experience, was found to influence student satisfaction with the library’s online services.Overall, students reported satisfaction with the university’s online library resources and services. Comments submitted to open-ended questions regarding areas for improvement to the online library provide library administrators with avenues for development to increase awareness of library services, focus improvement in navigation, and enhance student satisfaction.

    2015-06-01

    Humans' ability to count by verbally labeling discrete quantities is unique in animal cognition. The evolutionary origins of counting algorithms are not understood. We report that nonhuman primates exhibit a cognitive ability that is algorithmically and logically similar to human counting. Monkeys were given the task of choosing between two food caches. First, they saw one cache baited with some number of food items, one item at a time. Then, a second cache was baited with food items, one at a time. At the point when the second set was approximately equal to the first set, the monkeys spontaneously moved to choose the second set even before that cache was completely baited. Using a novel Bayesian analysis, we show that the monkeys used an approximate counting algorithm for comparing quantities in sequence that is incremental, iterative, and condition controlled. This proto-counting algorithm is structurally similar to formal counting in humans and thus may have been an important evolutionary precursor to human counting. © The Author(s) 2015.

    Science.gov (United States)

    1972-01-01

    The design, fabrication, and tests of a prototype white blood cell counting system for use in the Skylab IMSS are presented. The counting system consists of a sample collection subsystem, sample dilution and fluid containment subsystem, and a cell counter. Preliminary test results show the sample collection and the dilution subsystems are functional and fulfill design goals. Results for the fluid containment subsystem show the handling bags cause counting errors due to: (1) adsorption of cells to the walls of the container, and (2) inadequate cleaning of the plastic bag material before fabrication. It was recommended that another bag material be selected.

    To assess the effect of an antismoking advertisement under real-world conditions. Design Quasi-experimental study. Multiplex cinema in Kiel, Germany; 4073 patrons were surveyed after having viewed a movie. Some 4005 patrons were > or = 10 years old (28.7% between 10 and 17 years). A total of 654 subjects (16.3%) were smokers. In the intervention condition (weeks 1 and 3), a 30-second antismoking advertisement-accentuating long-term health consequences of smoking and promoting cessation-was shown prior to all movies; in the control condition (weeks 2 and 4) no such spot was shown. (i) Awareness of smoking in the movie, (ii) approval of smoking in the movie, (iii) attitude towards smoking, (iv) intention to smoke in the future and (v) desire to smoke among smokers. Findings Patrons who were exposed to the antismoking advertisement were more likely to be female, but did not differ with respect to smoking status. After controlling for gender differences, patrons exposed to the antismoking advertisement had (i) higher awareness of smoking in the movies, (ii) lower levels of approval of smoking in the movies, and (iii) a more negative attitude towards smoking in general compared with those not exposed. Among smokers, smoking in the movies increased urge to smoke, but there was no interaction between smoking in the movies and experimental condition. Study results suggest that placing an antismoking advertisement before movies can affect attitudes towards smoking, bolstering evidence in support of such policies.

    2015-09-01

    Full Text Available As digital comic book consumption continues to rise in popularity, the comic book community appears conflicted over the effects that digital scans have on the meaning of collecting and reading comic books. Historically, comic ownership served as the locus of comic fan social capital; will digital scans hold the same cultural capital as printed books? And does postpurchased digital scan dissemination primarily hurt copyright holders through lost sales, or does it help through social promotion? Building on an analysis of fan attitudes toward digital comic book texts, we seek to account for the limitations of locality by surveying the attitudes of comic book store patrons concerning their attitudes toward physical and digital comic book texts.

    2012-01-01

    Any effort to decrease the toll of drunk driving must include efforts directed at people who drink in bars, particularly young adults who use motor vehicles after drinking. We designed a multifaceted social marketing campaign, Last Call, to increase the use of designated drivers and safe rides homes among 21-34-year olds. There were three components to the intervention: (1) use of taxi stands to promote taxi use; (2) point-of-sale information to patrons at partner bars and (3) a mass media campaign to support the designated driver/safe ride home message. Among the heaviest drinkers, the programme significantly increased the use of designated drivers and increased the use of taxis by 63%.

    Full Text Available Abstract Background "Smoke-Free" legislation prohibiting smoking in all enclosed public places was introduced in March 2006. This qualitative study presents insights from bar workers about their observations of the changing social bar environment, changing patrons' behaviours and challenges bar workers have faced in managing smoke-free legislation. Methods Twelve in-depth interviews were conducted between November 2006 and January 2007 with a purposively-selected sample of bar workers, identified from a larger quantitative study evaluating the impact of the legislation in Scotland [the Bar Workers' Health and Environmental Tobacco Smoke Exposure project (BHETSE]. Results Bar workers all spoke of the improvements the legislation had brought to their working lives and the greater comfort it appeared to offer patrons. Bar workers reported that patrons were generally quick to accept and comply with the new law, and that families had become a greater feature of pub life since the legislation. However, they expressed concerns that older men seemed to have had most difficulty adjusting to the legislation and lack of knowledge about the best practices they should adopt in order to reduce the risks of unattended drinks being spiked and of anti-social behaviour associated with patrons moving outside to smoke. Conclusion Smoke-free legislation is changing the social context of smoking in Scotland. Further research to assess the impact the legislation is having on older male smokers and on the incidence of drink spiking would be useful. More specifically, bar workers would benefit from guidance on how to manage issues arising from patrons moving outside to smoke.

    Introduction Use of non-cigarette tobacco products is common, and e-cigarette use is increasing among young adults. We aimed to identify use of other tobacco products among young adult bar patrons in the context of a bar-based intervention to decrease cigarette smoking. Methods 2291 cross-sectional surveys were collected from young adults in bars in Albuquerque, New Mexico using time–location sampling between 2011 and 2013 (N = 1142 in 2011, N = 1149 in 2012–2013), 2 and 3 years into an intervention to reduce cigarette use, and analyzed in 2014–2015. Participants reported current (i.e. past 30-day) use of cigarettes, snus, dip, cigarillos, hookah, and e-cigarettes, demographics, and tobacco-related attitudes. Multiple imputation was used to account for planned missing data. Logistic regression determined correlates of multiple tobacco product use. Results Cigarette smoking in the population decreased during the intervention from 43% to 37%. Over 60% of current cigarette smokers reported poly-use, most frequently with e-cigarettes (46%) and hookah (44%), followed by cigarillos (24%), dip (15%), and snus (14%) in 2012–2013. Among cigarette smokers, current e-cigarette use increased, while use of other products decreased during the intervention. Odds of poly-use (versus smoking cigarettes only) were greater among males and those reporting past 30-day binge drinking, and lower in those who strongly believed secondhand smoke exposure is harmful. Conclusions Among young adult bar patrons in Albuquerque, New Mexico, most cigarette smokers reported currently using at least one other tobacco product. Public health interventions should address use of all tobacco products, use of which may rise despite decreased cigarette use. PMID:26666395

Los tipos de vegetación fueron matorral, pastizal mediano, pastizal halófito con suelo aluvial profundo y bosque con suelo coluvial. Los datos fueron analizados como categóricos y se realizó la comparación de medias mediante una prueba de proporciones en distribuciones normales. La semilla germinó en los suelos provenientes de las cuatro áreas con diferentes tipos de vegetación y patrones de humedad-sequía. La mayor emergencia, 92%, se presentó en el suelo aluvial profundo de pastizal mediano con una secuencia de humedad-sequía de 120 mm que representa una precipitación de 12 días al año (P < 0.0008. Las plantas sobrevivieron de 12 a 24 días sin riego, pero no a los 36 días. El pasto M. repens es capaz de germinar en cualquier suelo proveniente de las cuatro áreas con diferentes tipos de vegetación estudiados y la poca o abundante humedad no representa un impedimento para su emergencia.

    2010-01-01

    Full Text Available Abstract Background The manual counting of cells by microscopy is a commonly used technique across biological disciplines. Traditionally, hand tally counters have been used to track event counts. Although this method is adequate, there are a number of inefficiencies which arise when managing large numbers of samples or large sample sizes. Results We describe software that mimics a traditional multi-register tally counter. Full customizability allows operation on any computer with minimal hardware requirements. The efficiency of counting large numbers of samples and/or large sample sizes is improved through the use of a "multi-count" register that allows single keystrokes to correspond to multiple events. Automatically updated multi-parameter values are implemented as user-specified equations, reducing errors and time required for manual calculations. The user interface was optimized for use with a touch screen and numeric keypad, eliminating the need for a full keyboard and mouse. Conclusions Our software provides an inexpensive, flexible, and productivity-enhancing alternative to manual hand tally counters.

    2015-01-01

    Location-based sampling is a method to obtain samples of people within ecological contexts relevant to specific public health outcomes. Random selection increases generalizability; however, in some circumstances (such as surveying bar patrons), recruitment conditions increase risks of sample bias. We attempted to recruit representative samples of bars and patrons in six California cities, but low response rates precluded meaningful analysis. A systematic review of 24 similar studies revealed that none addressed the key shortcomings of our study. We recommend steps to improve studies that use location-based sampling: (i) purposively sample places of interest, (ii) use recruitment strategies appropriate to the environment, and (iii) provide full information on response rates at all levels of sampling.

El propósito de este estudio fue obtener los patrones proteicos de bandeo mediante la técnica de electroforesis en gel de poliacrilamida bajo condiciones desnaturalizantes para, hordeínas de semilla seca de cinco variedades mexicanas de cebada. Asimismo, se obtuvieron los patrones de hordeínas en malta procesada a partir de cuatro variedades mexicanas y una variedad canadiense (Metcalfe. A continuación, algunas de las bandas diferenciales fueron identificadas mediante espectrometría de masas (EM utilizando distintos protocolos de digestión. En los patrones de semilla seca se encontraron diferencias entre las variedades mexicanas para las bandas correspondientes a un peso molecular de 100 kDa, 65 kDa y algunas de 37-45 kDa. En el caso de la malta, los patrones de las variedades mexicanas fueron muy contrastantes entre sí, así como con el observado en Metcalfe, lo que sugiere que el procesamiento de hordeínas durante la germinación y el secado de la malta depende de cada variedad. Finalmente, en la identificación por EM se demostró que el uso de digestión con tripsina es adecuado para distinguir hordeínas B y γ en malta, mientras que el uso de digestión secuencial con quimotripsina y tripsina favorece la identificación de hordeínas C en semilla seca.

  10. From Paternalistic to Patronizing: How Cultural Competence Can Be Ethically Problematic.

    2017-08-28

    Cultural competence literature and training aim to equip healthcare workers to better understand patients of different cultures and value systems, in an effort to ensure effective and equitable healthcare services for diverse patient populations. However, without nuanced awareness and contextual knowledge, the values embedded within cultural competence practice may cripple rather than empower the very people they mean to respect. A narrow cultural view can lessen cultural understanding rather than grow it. In its first part, this paper argues that a hasty, unrestrained, and uneducated willingness to accept something as a cultural good, despite being well intentioned, can still cause significant harms-particularly when based on false, misinformed, and stereotypical conceptions-including the minimization of issues, the reinforcement of stereotypes, and the impediment of cultural change. The second part of this paper examines medical autonomy within the context of Saudi Arabian women. It pushes back on the common perception that Saudi women, by virtue of culture and religion, view dependency on and deference to male relatives as a cultural good. Through a historical examination and a presentation of the current women's movement in Saudi Arabia, it is argued that the continued assumption that personal agency is a value external to Saudi women is false, misguided, and ethically problematic. Lastly, this paper considers some approaches to help providers navigate the narrow grounds between paternalism and patronization when caring for patients.

Se plantea que los patrones demográficos en las misiones guaraníes fueron únicos, lo cual se aprecia al ser comparados con las misiones de otras fronteras de la América española, como la del norte de México. Mientras que las poblaciones nativas disminuyeron en estas misiones, las poblaciones guaraníes se recuperaron y crecieron a través de la reproducción natural, aun después de una severa mortalidad causada por las epidemias. Muchos pueblos nativos obligados a vivir en las misiones o en otras fronteras españolas de las Américas enfrentaron una virtual extinción biológica y cultural, mientras que los guaraníes siguieron siendo una población viable después de la expulsión de los jesuitas en 1768 y el traspaso de las antiguas misiones durante las tres primeras décadas del siglo XIX.

    2013-01-01

    The Maya had a very elaborate and accurate calendar. First, the Mayan Long Count Calendar (LCC) was used to point historical events from a selected "beginning of time". It is also characterized by the existence of a religious month Tzolk'in of 260 days and a civic year Haab' of 365 days. The LCC is supposed to begin on 11 August -3114 BC known as the Goodman-Martinez-Thompson (GMT) correlation to the Gregorian calendar based on historical facts and end on 21 December 2012 corresponding to a period of approximately 5125 years or 13 Baktun. We propose here to explain the origin the 13 Baktun cycle, the Long Count Periods and the religious month Tzolk'in.

    A double occurrence word $w$ over a finite alphabet $\\Sigma$ is a word in which each alphabet letter appears exactly twice. Such words arise naturally in the study of topology, graph theory, and combinatorics. Recently, double occurrence words have been used for studying DNA recombination events. We develop formulas for counting and enumerating several elementary classes of double occurrence words such as palindromic, irreducible, and strongly-irreducible words.

    In 1999 Kannan, Tetali and Vempala proposed a MCMC method to uniformly sample all possible realizations of a given graphical degree sequence and conjectured its rapidly mixing nature. Recently their conjecture was proved affirmative for regular graphs (by Cooper, Dyer and Greenhill, 2007), for regular directed graphs (by Greenhill, 2011) and for half-regular bipartite graphs (by Miklós, Erdős and Soukup, 2013). Several heuristics on counting the number of possible realizations exist (via sampling processes), and while they work well in practice, so far no approximation guarantees exist for such an approach. This paper is the first to develop a method for counting realizations with provable approximation guarantee. In fact, we solve a slightly more general problem; besides the graphical degree sequence a small set of forbidden edges is also given. We show that for the general problem (which contains the Greenhill problem and the Miklós, Erdős and Soukup problem as special cases) the derived MCMC process is rapidly mixing. Further, we show that this new problem is self-reducible therefore it provides a fully polynomial randomized approximation scheme (a.k.a. FPRAS) for counting of all realizations.

    Full Text Available The presence of somatic cells in milk is a widely disputed issue in milk production sector. The somatic cell counts in raw milk are a marker for the specific cow diseases such as mastitis or swollen udder. The high level of somatic cells causes physical and chemical changes to milk composition and nutritional value, and as well to milk products. Also, the mastitic milk is not proper for human consumption due to its contribution to spreading of certain diseases and food poisoning. According to these effects, EU Regulations established the maximum threshold of admitted somatic cells in raw milk to 400000 cells / mL starting with 2014. The purpose of this study was carried out in order to examine the raw milk samples provided from small farms, industrial type farms and milk processing units. There are several ways to count somatic cells in milk but the reference accepted method is the microscopic method described by the SR EN ISO 13366-1/2008. Generally samples registered values in accordance with the admissible limit. By periodical monitoring of the somatic cell count, certain technological process issues are being avoided and consumer’s health ensured.

    Manual reticulocyte counts were examined under light microscopy, using the property whereby supravital stain precipitates residual ribosomal RNA versus the automated flow methods, with the suggestion that in the latter there is greater precision and an ability to determine both mature and immature reticulocyte fractions. Three hundred and forty-one venous blood samples of patients were analyzed of whom 224 newborn and the rest adults; 51 males and 66 females, with ages between 0 and 89 years, as part of the laboratory routine for hematological examinations at the Clinical Laboratory of the Hospital Universitário do Oeste do Paraná. This work aimed to compare manual and automated methodologies for reticulocyte countings and evaluate random and systematic errors. The results obtained showed that the difference between the two methods was very small, with an estimated 0·4% systematic error and 3·9% random error. Thus, it has been confirmed that both methods, when well conducted, can reflect precisely the reticulocyte counts for adequate clinical use.

The Saint appears in public spaces in occasion of rallies, marches, interventions and demonstrations, and its popularity has lead to development of a precise and colorful iconography, hagiography and rituals. This popularity conversely is also the sign of the gravity of the issue of precarity in Italy and Europe .San Precario epitomises current Italian activist practices. These practices, although specifically Italian, intersect with similar realities in Europe and are based on mythopoetic narratives and actions and mediatic embodiments. This paper analysis a variety of texts produced around San Precario, from posters, saint cards, product cards, videos, "official" narratives, personal accounts, relating them to the political debate surrounding precarity.

    Full Text Available En este estudio se revisa la hipótesis sobre la supuesta singularidad genética de las poblaciones del Chaco argentino (alta diversidad intragrupal y baja diferenciación intergrupal a partir del estudio de secuencias de la RHV-I del ADN mitocondrial. El análisis de 204 individuos del Chaco argentino y más de 2000 de diversas poblaciones y regiones de Centro y Sudamérica corrobora y refina los resultados derivados del estudio de haplogrupos mitocondriales: A diferencia de lo observado en otras regiones, las poblaciones del Chaco argentino presentan una gran diversidad genética, conjuntamente con una baja distancia genética entre poblaciones. Estos rasgos configuran un patrón único, que puede ser explicado por la forma de vida de sus habitantes antes del contacto con los europeos y las características de transición geográfica de la región chaqueña. Sin embargo, no pueden excluirse como explicaciones igualmente plausibles un posible error de muestreo o bien la ruptura post contacto de las formas tradicionales de parentesco. En otro orden, la alta variación genética encontrada en la región, geográficamente intermedia dentro de Sudamérica, no se ajusta al modelo que propone la existencia de dos patrones de diversidad genética nítidamente diferentes para las poblaciones nativas del Este y del Oeste del Continente, sostenido por otros autores.

    The administration of radionuclides to children for diagnostic procedures should be carried out only if there is a strong clinical indication. The amount of activity administered may be reduced according to body weight, body surface area or other appropriate criteria. In Brazil, activities used for pediatric patients were evaluated (2003-2005) in sixteen selected public and private institutions in Northeast, Southeast and South geographical regions. The present work presents radiopharmaceuticals activities used in Brazil compared with international surveys performed in USA in 2005 and in the European Union in 2007. The activities per patient weight and minimum and maximum activities used per Brazilian installations were compared with those used in USA installations. Per patients, it was calculated the ideal minimum administered activity for each type of radiopharmaceutical by body weight according the Pediatric Dosage Card (PDC) criteria. It was not possible to compare activities for all radiopharmaceuticals used in Brazil because some are not more used outside, e.g. {sup 131}I-NaI, which is replaced by {sup 123}I-NaI for thyroid imaging. The discrepancy between activities used in Brazil compared with those used in USA and Europe may be attributed to the heterogeneity of Brazilian imaging equipment and lack for specific children protocols. The disadvantages for using fractions of adult activities are: necessity of minimum statistical counting for assurance of image quality and dependence upon equipment calibration. It was concluded that is necessary to establish standard criteria for radiopharmaceuticals activities applied to pediatric patients in Brazil and the risks due to additional activities should be estimated individually.

    Digital Coincidence Counting (DCC) is a new technique in radiation metrology, based on the older method of analogue coincidence counting. It has been developed by the Australian Nuclear Science and Technology Organisation (ANSTO), in collaboration with the National Physical Laboratory (NPL) of the United Kingdom, as a faster more reliable means of determining the activity of ionising radiation samples. The technique employs a dual channel analogue-to-digital converter acquisition system for collecting pulse information from a 4π beta detector and an NaI(Tl) gamma detector. The digitised pulse information is stored on a high-speed hard disk and timing information for both channels is also stored. The data may subsequently be recalled and analysed using software-based algorithms. In this letter we describe some recent results obtained with the new acquistion hardware being tested at ANSTO. The system is fully operational and is now in routine use. Results for 60Co and 22Na radiation activity calibrations are presented, initial results with 153Sm are also briefly mentioned.

El trabajo se llevó a cabo desde dos perspectivas: el punto de vista de expertos técnicos y la percepción de un grupo social de adultos mayores. Los resultados reflejaron que los patrones propuestos propician la creación de interfaces bien diseñadas capaces de ofrecer una mejor experiencia de uso y promueven un impacto positivo en la calidad de vida de los adultos mayores.

    Full Text Available The condition of women throughout the world is marked by countless injustices and violations of the most fundamental rights established by the Universal Declaration of human rights and every culture is potentially prone to commit discrimination against women in various forms. Women are worse fed, more exposed to physical violence, more exposed to diseases and less educated; they have less access to, or are excluded from, vocational training paths; they are the most vulnerable among prisoners of conscience, refugees and immigrants and the least considered within ethnic minorities; from their very childhood, women are humiliated, undernourished, sold, raped and killed; their work is generally less paid compared to men’s work and in some countries they are victims of forced marriages. Such condition is the result of old traditions that implicit gender-differentiated education has long promoted through cultural models based on theories, practices and policies marked by discrimination and structured differentially for men and women. Within these cultural models, the basic educational institutions have played and still play a major role in perpetuating such traditions. Nevertheless, if we want to overcome inequalities and provide women with empowerment, we have to start right from the educational institutions and in particular from school, through the adoption of an intercultural approach to education: an approach based on active pedagogy and on methods of analysis, exchange and enhancement typical of socio-educational animation. The intercultural approach to education is attentive to promote the realisation of each individual and the dignity and right of everyone to express himself/herself in his/her own way. Such an approach will give women the opportunity to become actual agents of collective change and to get the strength and wellbeing necessary to count and be counted as human beings entitled to freedom and equality, and to have access to all

    Jimenez F, E. A.

    2014-07-01

    In this paper a classification of the radiological and nuclear accidents is presented, describing which the activities are, where they have occurred, their incidence and the learned lessons in these successes. The radiological accidents in which radioactive materials intervene can occur anywhere, and they are related to no controlled dangerous sources (abandoned, lost, stolen, or found sources), improper use of dangerous industrial and medical sources, exposition and contamination of people in general by an unknown origin, serious over expositions, menaces and willful misconduct, emergencies during transportation of radioactive material. A person can receive a dose of radiation from an external source, because of radioactive material placed on skin or on equipment, or because of ingestion or inhalation of radiological particles. The ingestion or the inhalation of radioactive material can cause an internal dose to the whole body or to a specific organ during a period of time. That is why a description of the processes of incorporation, the stages of incorporation and a description of the biokinetic models are also realized to understand the ingestion, transference and the excretion of the radioactive elements. In order to offer help to a victim of internal contamination, the dosimetric and medical diagnosis is very important. The most important techniques of dosimetric diagnosis are the dosimetry in vivo (cytogenetics and the counting in vivo of the whole body) and the bioassays. These techniques allow obtain data such as the radionuclide, the target organ, the absorbed dose, etc. At the same time, the doctor in charge must be attentive to the patients symptoms and their manifestation time, since they are an indicator, first, the patient suffered an irradiation, and second, of the range esteem of the received radiation dose. These are the parameters that are useful as criterion to decide if a person has to receive some treatment and select the methodologies that

    Cell counting is an important routine procedure. However, to date there is no comprehensive, easy to use, and inexpensive solution for routine cell counting, and this procedure usually needs to be performed manually. Here, we report a complete solution for automatic cell counting in which a conventional light microscope is equipped with a web camera to obtain images of a suspension of mammalian cells in a hemocytometer assembly. Based on the ImageJ toolbox, we devised two algorithms to automatically count these cells. This approach is approximately 10 times faster and yields more reliable and consistent results compared with manual counting.

    Full Text Available Los cambiantes modelos de desarrollo urbano en Latinoamérica han atraído la atención hacia la segregación residencial. Con datos del censo mexicano del año 2000, este artículo describe los patrones espaciales y niveles de segregación por etnicidad y estatus socioeconómico en más de cien ciudades, confirmando que muchos de los que son reconocidos se mantienen en muchas y variadas ciudades. Los hogares con ingresos bajos y empleos informales tienden a vivir en áreas periféricas de la ciudad, mientras que los de ingresos altos y empleados formalmente están más concentrados. Las áreas de ingresos elevados son más densas y socioeconómicamente diversas. Más aún, existe una relación estadísticamente significativa entre segregación y tamaño de ciudad: las ciudades mayores están más segregadas. De manera similar, las diferencias regionales también son grandes y estadísticamente significativas, lo que demuestra la importancia tanto de los períodos históricos de urbanización del país como de los distintos niveles de desarrollo económico regional.Changing patterns of urban development in Latin America have drawn increasing attention to residential segregation, yet there are no systematic quantitative analyses in the literature. Using data from the Mexican census of2000, this paper measures spatial patterns and levels of segregation by ethnicity and socioeconomic status in over one hundred cities. Findings confirm that many recognized patterns hold across a wide variety of cities. Low-income and informally employed households tend to live in peripheral areas of the city, while high-income households are more centrally concentrated. High-income areas are denser and more socioeconomically diverse. Further, the paper shows that there is a statistically significant relationship between segregation by income and city size; larger cities are more segregated. Similarly, regional differences in patterns of segregation are also

Se realizaron diez parcelas de 20 x 50 m (1 ha, distribuidas así: cuatro en tierra firme, tres en plano inundable bien drenado y tres en plano inundable mal drenado. Se registraron 39.552 individuos pertenecientes a 45 especies que se agrupan en 15 familias y 22 géneros. La especie más abundante, en total y para los planos inundables, es Trichomanes vandenboschii, mientras que para tierra firme es Adiantum  tomentosum. El paisaje más diverso en cuanto a número de especies es tierra firme y el menos diverso es el plano inundable mal drenado. De acuerdo a los métodos utilizados para evaluar la distribución espacial: gráfica de las posiciones de cada individuo dentro de la parcela, método de cuadrantes contiguos (TTLQV y el índice  estandarizado de Morisita, la comunidad y las especies más abundantes presentan una distribución agregada, con grupos que se presentan entre 3 y 21 m en tierra firme y 3 y 24 m en los planos inundables, las diferencias entre paisajes son en la intensidad y en las distancias de repetición del patrón. Las especies menos abundantes, presentaron una distribución agregada o aleatoria. Los factores ambientales que mejor

    Mariconda, Carlo

    2016-01-01

    This book provides an introduction to combinatorics, finite calculus, formal series, recurrences, and approximations of sums. Readers will find not only coverage of the basic elements of the subjects but also deep insights into a range of less common topics rarely considered within a single book, such as counting with occupancy constraints, a clear distinction between algebraic and analytical properties of formal power series, an introduction to discrete dynamical systems with a thorough description of Sarkovskii’s theorem, symbolic calculus, and a complete description of the Euler-Maclaurin formulas and their applications. Although several books touch on one or more of these aspects, precious few cover all of them. The authors, both pure mathematicians, have attempted to develop methods that will allow the student to formulate a given problem in a precise mathematical framework. The aim is to equip readers with a sound strategy for classifying and solving problems by pursuing a mathematically rigorous yet ...

    Howland, Gregory A; Ware, Matthew R; Howell, John C

    2013-01-01

    We demonstrate a compressed sensing, photon counting lidar system based on the single-pixel camera. Our technique recovers both depth and intensity maps from a single under-sampled set of incoherent, linear projections of a scene of interest at ultra-low light levels around 0.5 picowatts. Only two-dimensional reconstructions are required to image a three-dimensional scene. We demonstrate intensity imaging and depth mapping at 256 x 256 pixel transverse resolution with acquisition times as short as 3 seconds. We also show novelty filtering, reconstructing only the difference between two instances of a scene. Finally, we acquire 32 x 32 pixel real-time video for three-dimensional object tracking at 14 frames-per-second.

  16. Generalized Entropy Concentration for Counts

    CERN Document Server

    Oikonomou, Kostas N

    2016-01-01

    We consider the phenomenon of entropy concentration under linear constraints in a discrete setting, using the "balls and bins" paradigm, but without the assumption that the number of balls allocated to the bins is known. Therefore instead of \\ frequency vectors and ordinary entropy, we have count vectors with unknown sum, and a certain generalized entropy. We show that if the constraints bound the allowable sums, this suffices for concentration to occur even in this setting. The concentration can be either in terms of deviation from the maximum generalized entropy value, or in terms of the norm of the difference from the maximum generalized entropy vector. Without any asymptotic considerations, we quantify the concentration in terms of various parameters, notably a tolerance on the constraints which ensures that they are always satisfied by an integral vector. Generalized entropy maximization is not only compatible with ordinary MaxEnt, but can also be considered an extension of it, as it allows us to address...

  19. Addressing Rural Library Technology Budgets with Single Board Computers: Testing the APC 8950 Rock Circuit Board Computer for Patron Access

    Directory of Open Access Journals (Sweden)

    Michael D. Wells

    2014-04-01

    Full Text Available Over the last decade, libraries have faced enormous budgetary challenges when it comes to implementing new technologies. These challenges are very pronounced in rural areas where libraries struggle to develop and define a path for purchasing and replacing systems that have become outdated. The author attempted to create a unit to replace aging OPAC terminals and to provide a low cost computing option for budget constrained rural libraries. The initial attempt detailed in this paper involved purchasing and configuring an APC 8950 Rock single board computer. Unfortunately, due to limitations of this APC unit’s existing Android based operating system, the initial effort failed to yield a computer that could be used in a library by average patrons. Future plans are outlined for the development of a second system using the more broadly accepted Raspberry Pi platform. The success of this technological endeavor may empower libraries and patrons in their communities to have more control of the technology they develop and use in the future.

  5. Counting pairs of faint galaxies

    Woods, D; Richer, H B; Woods, David; Fahlman, Gregory G; Richer, Harvey B

    1995-01-01

    The number of close pairs of galaxies observed to faint magnitude limits, when compared to nearby samples, determines the interaction or merger rate as a function of redshift. The prevalence of mergers at intermediate redshifts is fundamental to understanding how galaxies evolve and the relative population of galaxy types. Mergers have been used to explain the excess of galaxies in faint blue counts above the numbers expected from no-evolution models. Using deep CFHT (I\\leq24) imaging of a ``blank'' field we find a pair fraction which is consistent with the galaxies in our sample being randomly distributed with no significant excess of ``physical'' close pairs. This is contrary to the pair fraction of 34\\%\\pm9\\% found by Burkey {\\it et al.} for similar magnitude limits and using an identical approach to the pair analysis. Various reasons for this discrepancy are discussed. Colors and morphologies of our close pairs are consistent with the bulk of them being random superpositions although, as indicators of int...

    We derive the contribution to relativistic galaxy number count fluctuations from vector and tensor perturbations within linear perturbation theory. Our result is consistent with the the relativistic corrections to number counts due to scalar perturbation, where the Bardeen potentials are replaced with line-of-sight projection of vector and tensor quantities. Since vector and tensor perturbations do not lead to density fluctuations the standard density term in the number counts is absent. We apply our results to vector perturbations which are induced from scalar perturbations at second order and give numerical estimates of their contributions to the power spectrum of relativistic galaxy number counts.

    One-to-One relationship management is a strategy that focuses on the academic library as a point of service. It provides the librarian with a methodology for utilizing currently available technology, which when combined with transaction information that the librarian collects from each differentiated patron interactions, enables the library to offer a range of individual customized services for its best patrons. This strategy is facilitated by the availability of low-cost high-speed computers and sophisticated telecommunication networks. This paper explores the contribution that affordable technology makes to the academic library's homepage rapidly becoming a new frontier platform for the promotion, delivery, and utilization of academic resources and services. In addition, the following issues are discussed: opportunities created by the enlarged cyber collections with the integration of the traditional collections; the role of privacy to insure patron participation; One-to-One relationship management strategy steps of patron identification, differentiation, interaction, and customization; and the practical application of customization in the academic library environment.

  14. Counting losses due to saturation effects of scintillation counters at high count rates

    CERN Document Server

    Hashimoto, K

    1999-01-01

    The counting statistics of a scintillation counter, with a preamplifier saturated by an overloading input, are investigated. First, the formulae for the variance and the mean number of counts, accumulated within a given gating time, are derived by considering counting-loss effects originating from the saturation and a finite resolving time of the electronic circuit. Numerical examples based on the formulae indicate that the saturation makes a positive contribution to the variance-to-mean ratio and that the contribution increases with count rate. Next the ratios are measured under high count rates when the preamplifier saturation can be observed. By fitting the present formula to the measured data, the counting-loss parameters can be evaluated. Corrections based on the parameters are made for various count rates measured in a nuclear reactor. As a result of the corrections, the linearity between count rate and reactor power can be restored.

    Full Text Available La diferenciación rápida de colonias bacterianas es esencial en muchos campos industriales, científicos y de salud humana y animal. Generalmente esa diferenciación se logra por técnicas microscópicas, bioquímicas o genéticas muy elaboradas que requieren tiempo y entrenamiento. En este estudio se utilizaron técnicas de análisis de imágenes sobre patrones de difracción de luz láser para evaluar su sensibilidad en la diferenciación de colonias bacterianas. Adicionalmente se estudió el efecto del tiempo de crecimiento de las colonias en la generación de estos patrones y se determinó la influencia de la cantidad de medio de cultivo en la difracción de luz láser. Los patrones de difracción del láser se obtuvieron sobre cultivos puros de cinco aislamientos bacterianos B1, B2, B3, B2Ca y B2Cb. En la primera prueba de diferenciación se utilizaron colonias de B2, B3, B2Ca. En el estudio del efecto del tiempo de crecimiento sobre patrones de difracción, las bacterias B1 y B2Cb con uno o dos días de crecimiento. Finalmente, el efecto de la cantidad de medio de cultivo en la difracción de la luz, se evaluó en una prueba en cajas petri con 10, 15 o 20 ml de medio de cultivo estéril sin colonias de bacterias. Mediante un análisis de escalado multidimensional realizado con los parámetros de textura extraídos de las imágenes de los patrones, se obtuvo un agrupamiento adecuado de los patrones asociados a las colonias de cada bacteria evaluada, lo cual indicó que las colonias bacterianas se pueden diferenciar por sus patrones de difracción. Adicionalmente se encontró que no hay variaciones significativas en los patrones de difracción obtenidos de dos aislamientos bacterianos en dos tiempos de crecimiento. El espesor del medio de cultivo afectó la difracción del haz de luz pues patrones obtenidos de cajas petri con 10 ml se separan completamente de los patrones obtenidos con 15 y 20 ml, aunque no hay diferencias entre los dos

    Full Text Available En este trabajo se aborda la variabilidad a través de la clasificación y las coordinaciones inferenciales. Participaron 34 niños de cuatro años de edad que asisten a seis jardines infantiles de la ciudad de Cali (Colombia. Se utilizó una tarea que implica el uso de hasta cinco criterios de clasificación. Se empleó el método microgenético para obtener datos detallados sobre aspectos cualitativos y cuantitativos de cambio. Para cuantificar las variaciones de los desempeños, se recurrió a las matrices de transición (derivadas de los modelos de Markov. Los resultados arrojan tres tipos de variabilidad (patrones que responden a diferentes usos de la clasificación y diferentes niveles de coordinación inferencial. Se concluye que la variabilidad es la evidencia de los desequilibrios cognitivos.

    2013-01-01

    Libraries in the USA and globally are undergoing quiet revolution. Libraries are moving away from a philosophy that is collection-centered to one focused on service. Technology is key to that change. The Patron Driven Library explores the way technology has moved the focus from library collections to services, placing the reader at the center of library activities. The book reveals the way library users are changing, and how social networking, web delivery of information, and the uncertain landscape of e-print has energized librarians to adopt technology to meet a different model of the library while preserving core values. Following an introduction, the first part begins with the historical milieu, and moves on to current challenges for financing and acquiring materials, and an exploration of why the millennial generation is transformational. The second part examines how changes in library practice can create a culture for imagining library services in an age of information overflow. The final chapter asks: ...

    Full Text Available Introducción: El dolor neuropático tiene una gran repercusión sobre los pacientes que lo padecen. Es uno de los síndromes dolorosos más complejos y su origen es diverso. Suele presentarse con una clínica de dolor quemante, pulsante, afilado, como hormigueo. que puede acompañarse de hiperalgesia o alodinia. El dolor suele presentar también alteraciones del estado de ánimo, e incluso depresión, con un gran impacto sobre la actividad social y laboral del paciente y una notable disminución de la calidad de vida. El tratamiento es difícil y, a menudo, refractario a la terapia convencional. La eficacia de los opioides ha sido controvertida aunque estudios recientes demuestran que éstos son efectivos en el tratamiento del dolor neuropático. Objetivos: Conocer los patrones de uso de los opioides mayores en el tratamiento del dolor de origen neuropático. Material y métodos: Estudio epidemiológico, transversal, descriptivo y multicéntrico realizado por 107 especialistas de Unidades de Dolor de España, en pacientes afectos de dolor neuropático. El estudio constaba de un cuestionario que recogía los datos demográficos del paciente, el motivo de la consulta, la patología base del dolor, el tiempo transcurrido desde el diagnóstico, el tratamiento y la intensidad del dolor medida mediante EVA. Asimismo, se recogieron los datos demográficos del investigador, su experiencia y su entorno laboral. Las variables cuantitativas se indicaron como media y desviación estándar y las cualitativas como porcentajes. Se consideró significación estadística cuando p 7. Conclusiones: El tratamiento del dolor neuropático sigue un esquema multimodal donde los anticomiciales y antidepresivos juegan un papel importante; no obstante, los opioides mayores, sobre todo fentanilo TTS, se contemplan como un tratamiento de primera línea en este tipo de dolor.Introduction: Neuropathic pain exerts a great impact upon patients.

    Full Text Available Words that function as the subjects of verbs, objects of verbs or prepositions and which can have a plural form and possessive ending are known as nouns. They are described as referring to persons, places, things, states, or qualities and might also be used as an attributive modifier. In this paper, classes and subclasses of nouns shall be presented, then, noun countability branching into count and non-count nous shall be discussed. A number of present examples illustrating differences between count and non-count nouns and this includes determiner-head-co-occurrence restrictions of number, subject-verb agreement, in addition to some exceptions to this agreement rule shall be discussed. Also, the lexically inherent number in nouns and how inherently plural nouns are classified in terms of (+/- count are illustrated. This research will discuss partitive construction of count and non-count nouns, nouns as attributive modifier and, finally, conclude with the fact that there are syntactic difference between count and non-count in the English Language.

  14. Count response model for the CMB spots

    CERN Document Server

    Giovannini, Massimo

    2010-01-01

    The statistics of the curvature quanta generated during a stage of inflationary expansion is used to derive a count response model for the large-scale phonons determining, in the concordance lore, the warmer and the cooler spots of the large-scale temperature inhomogeneities. The multiplicity distributions for the counting statistics are shown to be generically overdispersed in comparison with conventional Poissonian regressions. The generalized count response model deduced hereunder accommodates an excess of correlations in the regime of high multiplicities and prompts dedicated analyses with forthcoming data collected by instruments of high angular resolution and high sensitivity to temperature variations per pixel.

    In this thesis we examine the method of counting B{bar B} events produced in the BABAR experiment. The original method was proposed in 2000, but improvements to track reconstruction and our understanding of the detector since that date make it appropriate to revisit the B Counting method. We propose a new set of cuts designed to minimize the sensitivity to time-varying backgrounds. We find the new method counts B{bar B} events with an associated systematic uncertainty of {+-} 0.6%.

  7. Statistical modelling for falls count data.

    Ullah, Shahid; Finch, Caroline F; Day, Lesley

    2010-03-01

    Falls and their injury outcomes have count distributions that are highly skewed toward the right with clumping at zero, posing analytical challenges. Different modelling approaches have been used in the published literature to describe falls count distributions, often without consideration of the underlying statistical and modelling assumptions. This paper compares the use of modified Poisson and negative binomial (NB) models as alternatives to Poisson (P) regression, for the analysis of fall outcome counts. Four different count-based regression models (P, NB, zero-inflated Poisson (ZIP), zero-inflated negative binomial (ZINB)) were each individually fitted to four separate fall count datasets from Australia, New Zealand and United States. The finite mixtures of P and NB regression models were also compared to the standard NB model. Both analytical (F, Vuong and bootstrap tests) and graphical approaches were used to select and compare models. Simulation studies assessed the size and power of each model fit. This study confirms that falls count distributions are over-dispersed, but not dispersed due to excess zero counts or heterogeneous population. Accordingly, the P model generally provided the poorest fit to all datasets. The fit improved significantly with NB and both zero-inflated models. The fit was also improved with the NB model, compared to finite mixtures of both P and NB regression models. Although there was little difference in fit between NB and ZINB models, in the interests of parsimony it is recommended that future studies involving modelling of falls count data routinely use the NB models in preference to the P or ZINB or finite mixture distribution. The fact that these conclusions apply across four separate datasets from four different samples of older people participating in studies of different methodology, adds strength to this general guiding principle.

  9. The Complexity of Approximately Counting Stable Matchings

    Chebolu, Prasad; Martin, Russell

    2010-01-01

    We investigate the complexity of approximately counting stable matchings in the $k$-attribute model, where the preference lists are determined by dot products of "preference vectors" with "attribute vectors", or by Euclidean distances between "preference points" and "attribute points". Irving and Leather proved that counting the number of stable matchings in the general case is $#P$-complete. Counting the number of stable matchings is reducible to counting the number of downsets in a (related) partial order and is interreducible, in an approximation-preserving sense, to a class of problems that includes counting the number of independent sets in a bipartite graph ($#BIS$). It is conjectured that no FPRAS exists for this class of problems. We show this approximation-preserving interreducibilty remains even in the restricted $k$-attribute setting when $k \\geq 3$ (dot products) or $k \\geq 2$ (Euclidean distances). Finally, we show it is easy to count the number of stable matchings in the 1-attribute dot-product ...

    Full Text Available La medición de descargas parciales (DP se sustenta en la detección y filtraje de pulsos de corriente que aparecen en una banda de frecuencia que abarca desde los kilohertzios hasta los gigahertzios, por tal motivo los detectores de descargas parciales (DDP poseen sistemas para desagregar dichos pulsos de corriente. Sin embargo, los DDP también permiten el paso de otras señales de alta frecuencia (ruidos que se mezclan con los pulsos de DP y afectan la medición, interpretación y caracterización de las DP. Para atenuar ese efecto, se han desarrollado distintas técnicas para separar los ruidos tanto asociados a las señales como los existentes en los patrones φ,q,n.  En este artículo se presentan los resultados obtenidos en la reducción de los ruidos asociados a la conmutación de tiristores y los ruidos esporádicos, de los patrones φ,q,n mediante el empleo de técnicas de procesamiento de imágenes digitales. The measurement of partial (PD discharges is sustained in the detection and filtration of current pulses which appear in a band of frequency that include from the kilohertz until the gigahertzios, for such a reason the detectors of partial (PDD discharges they possess systems for the separation of this current pulses. However, PDD also allows the step of other signals of high frequency, denominated noises, that mix with the pulses of PD and they affect measurement, interpretation and characterization of PD. To attenuate that effect, different techniques have been developed to separate the noises so much associated to the signs like the existent ones in the φ,q,n patterns. In this paper are presented the results obtained in the noise reduction of the noises associated to the thyristor’s commutation and the sporadic noises, in the φ,q,n patterns by means of the technical of digital images processing

    Mohamed Azmi Hassali

    Full Text Available OBJECTIVE: The study aims to evaluate the predictors of non-prescription medicine purchasing patterns among pharmacy patrons in Malaysia. METHODS: A cross-sectional nationwide study was undertaken in 2011 in sixty randomly selected community pharmacies across 14 Malaysian states. A pharmacy exit survey was conducted over a 6-month period across Malaysia. A one-stage random cluster sampling technique was employed as there was no national sampling framework available for conducting this survey. Face-to-face interviews using a validated and pre-tested questionnaire were conducted by trained data collectors. The non-prescription medicine purchasing pattern was explored and analysed descriptively. Chi-square/Fisher exact test was used to determine the association between study variables. Multinomial logistic regression analysis was used to determine the predictors of type of non-prescription medicine purchased. RESULTS: A total of 2729 pharmacy patrons agreed to participate in 60 selected pharmacy outlets. A total of 3462 non-prescription medicine were purchased during the study period with an average of 1.3 medicines per participant. Most of the non-prescription medicine purchased was meant for alimentary tract and metabolism (31.8%, followed by respiratory system (19.4% and musculoskeletal system (15.8% usage. Factors found to be associated with the choice of non-prescription medicine purchased were age group [χ2 = 170.75, (df = 57, p<0.01], locality [χ2 = 48.16, (df = 19, p<0.01], gender [χ2 = 32.93, (df = 13, p = 0.002], ethnic group [χ2 = 118.89, (df = 39, p<0.01] and type of occupation [χ2 = 222.434, (df = 117, p<0.01]. Non-prescription medicine purchased defined about 20% of the variance in the combination of predictors such as locality, gender, age, ethnicity, type of occupation and household income. CONCLUSION: The predictors for selection of non-prescription medicine were locality (urban or rural, gender, age, ethnicity, type of

    2013-03-01

    Full Text Available Abstract- The aim of this study was to find out more information on the acquisition of counting skill in preschool children. For this purpose, children’s judgment of acceptability of a counting activity was used to investigate whether children’s counting skills are governed by their implicit knowledge of a number of counting principles. Data showed that children easily recognized the violation of one or more counting principles in a one’s application of counting principles in sequences of English and Turkish count words, implying that children have the understanding of counting principles. The sessions on counting in Turkish make it very likely that the children were responding to violations of rules rather than merely violation of well-learning of count words. These results give additional support to the assumption that there are innate counting principles that rule young children’s counting.

    Spotlight surveys conducted by volunteers is a promising method to assess the abundance of nocturnally active mammals, but estimates are subject to bias if different observer groups differ in their ability to detect animals in the dark. We quantified the variation amongst volunteer spotlight...... with non-hunters and decreased as function of age but were independent of sex or educational background. If observer-specific detection probabilities were applied to real counting routes, point count estimates from inexperienced observers without a hunting background would only be 43 % (95 % CI, 39...

    Full Text Available Pattern generalization is considered one of the prominent routes for introducing students to algebra. However, not all generalizations are algebraic. In the use of pattern generalization as a route to algebra, we —teachers and educators— thus have to remain vigilant in order not to confound algebraic generalizations with other forms of dealing with the general. But how to distinguish between algebraic and non-algebraic generalizations? On epistemological and semiotic grounds, in this article I suggest a characterization of algebraic generalizations. This characterization helps to bring about a typology of algebraic and arithmetic generalizations. The typology is illustrated with classroom examples. La generalización de patrones es considerada como una de las formas más importantes de introducir el algebra en la escuela. Sin embargo, no todas las generalizaciones de patrones son algebraicas. Como consecuencia, en el uso de patrones como recurso didáctico, se debe tener mucho cuidado en no confundir generalizaciones algebraicas con otras formas de generalización. Ahora bien, ¿cómo distinguir entre las unas y las otras? En este articulo, basado en ideas epistemológicas y semióticas, sugiero una caracterización de generalizaciones algebraicas. Dicha caracterización permite establecer una tipología, la cual es ilustrada a través de ejemplos concretos.

    We are presenting of a photon counting laser altimeter simulator. The simulator is designed to be a theoretical and numerical complement for a Technology Demonstrator of the space born laser altimeter for planetary studies built on our university. The European Space Agency has nominated the photon counting altimeter as one of the attractive devices for planetary research. The device should provide altimetry in the range 400 to 1400 km with one meter range resolution under rough conditions - Sun illumination, radiation, etc. The general altimeter concept expects the photon counting principle laser radar. According to this concept, the simulator is based on photon counting radar simulation, which has been enhanced to handle planetary surface roughness, vertical terrain profile and its reflectivity. The simulator is useful complement for any photon counting altimeter both for altimeter design and for measured data analysis. Our simulator enables to model the orbital motion, range, terrain profile, reflectivity, and their influence on the over all energy budget and the ultimate signal to noise ratio acceptable for the altimetry. The simulator can be adopted for various air or space born application.

    Gender-based violence is a well-recognized risk factor for HIV infection among women. Alcohol use is associated with both gender-based violence and sexual risk behavior, but has not been examined as a correlate of both in a context of both high HIV risk and hazardous drinking. The purpose of this paper is to examine the association between recent abuse by a sex partner with alcohol and sexual risk behavior among female patrons of alcohol serving venues in South Africa. Specifically, the aim of this study is to determine whether sexual risk behaviors are associated with gender-based violence after controlling for levels of alcohol use. We surveyed 1,388 women attending informal drinking establishments in Cape Town, South Africa to assess recent history of gender-based violence, drinking, and sexual risk behaviors. Gender-based violence was associated with both drinking and sexual risk behaviors after controlling for demographics among the women. A hierarchical logistic regression analysis showed that after controlling for alcohol use sexual risk behavior remained significantly associated with gender-based violence, particularly with meeting a new sex partner at the bar, recent STI diagnosis, and engaging in transactional sex, but not protected intercourse or number of partners. In South Africa where heavy drinking is prevalent women may be at particular risk of physical abuse from intimate partners as well as higher sexual risk. Interventions that aim to reduce gender-based violence and sexual risk behaviors must directly work to reduce drinking behavior.

    Alcohol-serving venues in South Africa provide a location for HIV prevention interventions due to risk factors of patrons in these establishments. Understanding the association between mental health and risk behaviors in these settings may inform interventions that address alcohol use and HIV prevention. Participants (n = 738) were surveyed in 6 alcohol-serving venues in Cape Town to assess post-traumatic stress disorder (PTSD) and depression symptoms, traumatic experiences, sexual behavior, and substance use. Logistic regression models examined whether traumatic experiences predicted PTSD and depression. Generalized linear models examined whether substance use, PTSD, and depressive symptoms predicted unprotected sexual intercourse. Men and women were analyzed separately. Participants exhibited high rates of traumatic experiences, PTSD, depression, alcohol consumption, and HIV risk behaviors. For men, PTSD was associated with being hit by a sex partner, physical child abuse, sexual child abuse and HIV diagnosis; depression was associated with being hit by a sex partner, forced sex and physical child abuse. For women, both PTSD and depression were associated with being hit by a sex partner, forced sex, and physical child abuse. Unprotected sexual intercourse was associated with age, frequency and quantity of alcohol use, drug use, and PTSD for men and frequency and quantity of alcohol use, depression, and PTSD for women. Mental health in this setting was poor and was associated with sexual risk behavior. Treating mental health and substance-use problems may aid in reducing HIV infection. Sexual assault prevention and treatment after sexual assault may strengthen HIV prevention efforts.

    This ASIC is a counting mode front-end electronic optimized for the readout of CdZnTe/CdTe and silicon sensors, for possible use in applications where the flux of ionizing radiation is high. The chip is implemented in 0.25 μm CMOS technology. The circuit comprises 128 channels equipped with a transimpedance amplifier followed by a gain shaper stage with 21 ns peaking time, two discriminators and two 18-bit counters. The channel architecture is optimized for the detector characteristics in order to achieve the best energy resolution at counting rates of up to 5 M counts/second. The amplifier shows a linear sensitivity of 118 mV/fC and an equivalent noise charge of about 711 e−, for a detector capacitance of 5 pF. Complete evaluation of the circuit is presented using electronic pulses and pixel detectors.

  10. High Count Rate Electron Probe Microanalysis

    2002-01-01

    Reducing the measurement uncertainty of quantitative analyses made using electron probe microanalyzers (EPMA) requires a careful study of the individual uncertainties from each definable step of the measurement. Those steps include measuring the incident electron beam current and voltage, knowing the angle between the electron beam and the sample (takeoff angle), collecting the emitted x rays from the sample, comparing the emitted x-ray flux to known standards (to determine the k-ratio) and transformation of the k-ratio to concentration using algorithms which includes, as a minimum, the atomic number, absorption, and fluorescence corrections. This paper discusses the collection and counting of the emitted x rays, which are diffracted into the gas flow or sealed proportional x-ray detectors. The representation of the uncertainty in the number of collected x rays collected reduces as the number of counts increase. The uncertainty of the collected signal is fully described by Poisson statistics. Increasing the number of x rays collected involves either counting longer or at a higher counting rate. Counting longer means the analysis time increases and may become excessive to get to the desired uncertainty. Instrument drift also becomes an issue. Counting at higher rates has its limitations, which are a function of the detector physics and the detecting electronics. Since the beginning of EPMA analysis, analog electronics have been used to amplify and discriminate the x-ray induced ionizations within the proportional counter. This paper will discuss the use of digital electronics for this purpose. These electronics are similar to that used for energy dispersive analysis of x rays with either Si(Li) or Ge(Li) detectors except that the shaping time constants are much smaller. PMID:27446749

    A silicon-strip detector is developed for spectral computed tomography. The detector operates in photon-counting mode and allows pulse-height discrimination with 8 adjustable energy bins. In this work, we evaluate the count-rate performance of the detector in a clinical CT environment. The output counts of the detector are measured for x-ray tube currents up to 500 mA at 120 kV tube voltage, which produces a maximum photon flux of 485 Mphotons/s/mm2 for the unattenuated beam. The corresponding maximum count-rate loss of the detector is around 30% and there are no saturation effects. A near linear relationship between the input and output count rates can be observed up to 90 Mcps/mm2, at which point only 3% of the input counts are lost. This means that the loss in the diagnostically relevant count-rate region is negligible. A semi-nonparalyzable dead-time model is used to describe the count-rate performance of the detector, which shows a good agreement with the measured data. The nonparalyzable dead time τn for 150 evaluated detector elements is estimated to be 20.2±5.2 ns.

    We present a microscopic index formula for the degeneracy of dyons in four-dimensional N = 4 string theory. This counting formula is manifestly symmetric under the duality group, and its asymptotic growth reproduces the macroscopic Bekenstein-Hawking entropy. We give a derivation of this result in terms of the type 11 five-brane compactified on K3, by assuming that its fluctuations are described by a closed string theory on its world-volume. We find that the degeneracies are given in terms of the denominator of a generalized super Kac-Moody algebra. We also discuss the correspondence of this result with the counting of D-brane states.

    We describe an analysis of 3-GHz confusion-limited data from the Karl J. Jansky Very Large Array (VLA). We show that with minimal model assumptions, P(D), Bayesian and Markov-Chain Mone-Carlo (MCMC) methods can define the source count to levels some 10 times fainter than the conventional confusion limit. Our verification process includes a full realistic simulation that considers known information on source angular extent and clustering. It appears that careful analysis of the statistical properties of an image is more effective than counting individual objects.

    A standard objection to the Borda count, as an actual voting procedure, is that it is subject to agenda manipulation. The classical example is the introduction, in order to favour a candidate or option y, of a new option z ranked on every voter's preference scale immediately below y; y may as a result obtain the highest Borda count, although, if z had not been introduced, a different option would have done so. Strategic use of this device is not greatly to be feared, but it does point to a de...

    The purpose of the present study was to investigate the potential associations of binge drinking detected at the exit of nightclubs and risk behaviors and alcohol effects just after leaving the venue in a representative sample of Brazilian nightclub patrons according to sex. For this purpose, a portal survey study called Balada com Ciência was conducted in 2013 in the megacity of São Paulo, Brazil, using a two-stage cluster sampling survey design. Individual-level data were collected in 2422 subjects at the entrance and 1822 subjects at the exit of 31 nightclubs, and breath alcohol concentration (BrAC) was measured using a breathalyzer. The following day, 1222 patrons answered an online follow-up survey that included questions about risk behaviors and alcohol effects practiced just after leaving the nightclub. Weighted logistic regressions were used to analyze binge drinking associated with risk behaviors by sex. For both sexes, the most prevalent risk behaviors practiced after leaving a nightclub were drinking and driving (men=27.9%; women=20.4%), the use of illicit drugs (men=15.8%; women=9.4%) and risky sexual behavior (men=11.4%; women=6.8%). The practice of binge drinking increased the behavior of illicit drug use after leaving the nightclub by 2.54 times [95% CI: 1.26-5.09] among men who drank and increased the risk of an episode of new alcohol use by 5.80 times [95% CI: 1.50-22.44] among women who drank. Alcoholic blackouts were more prevalent among men [OR=8.92; 95% CI: 3.83-20.80] and women [OR= 5.31; 95% CI: 1.68-16.84] whose BrAC was equivalent to binge drinking compared with patrons with a lower BrAC. Public policies aiming to reduce patrons' BrAC at the exit of nightclubs, such as staff training in responsible beverage service and legislation to prevent alcohol sales to drunk individuals, would be useful to protect patrons from the risk behaviors associated with binge drinking in nightclubs.

    2017-06-01

    Crater count equilibrium occurs when new craters form at the same rate that old craters are erased, such that the total number of observable impacts remains constant. Despite substantial efforts to understand this process, there remain many unsolved problems. Here, we propose an analytical model that describes how a heavily cratered surface reaches a state of crater count equilibrium. The proposed model formulates three physical processes contributing to crater count equilibrium: cookie-cutting (simple, geometric overlap), ejecta-blanketing, and sandblasting (diffusive erosion). These three processes are modeled using a degradation parameter that describes the efficiency for a new crater to erase old craters. The flexibility of our newly developed model allows us to represent the processes that underlie crater count equilibrium problems. The results show that when the slope of the production function is steeper than that of the equilibrium state, the power law of the equilibrium slope is independent of that of the production function slope. We apply our model to the cratering conditions in the Sinus Medii region and at the Apollo 15 landing site on the Moon and demonstrate that a consistent degradation parameterization can successfully be determined based on the empirical results of these regions. Further developments of this model will enable us to better understand the surface evolution of airless bodies due to impact bombardment.

    2008-01-01

    Let H be a graph, and let C(H,G) be the number of (subgraph isomorphic) copies of H contained in a graph G. We investigate the fundamental problem of estimating C(H,G). Previous results cover only a few specific instances of this general problem, for example, the case when H has degree at most one (monomer-dimer problem). In this paper, we present the first general subcase of the subgraph isomorphism counting problem which is almost always efficiently approximable. The results rely on a new graph decomposition technique. Informally, the decomposition is a labeling of the vertices generating a sequence of bipartite graphs. The decomposition permits us to break the problem of counting embeddings of large subgraphs into that of counting embeddings of small subgraphs. Using this method, we present a simple randomized algorithm for the counting problem. For all decomposable graphs H and all graphs G, the algorithm is an unbiased estimator. Furthermore, for all graphs H having a decomposition where each of the bipa...

  2. Differential white cell count by centrifugal microfluidics.

    Energy Technology Data Exchange (ETDEWEB)

    Sommer, Gregory Jon; Tentori, Augusto M.; Schaff, Ulrich Y.

    2010-07-01

    We present a method for counting white blood cells that is uniquely compatible with centrifugation based microfluidics. Blood is deposited on top of one or more layers of density media within a microfluidic disk. Spinning the disk causes the cell populations within whole blood to settle through the media, reaching an equilibrium based on the density of each cell type. Separation and fluorescence measurement of cell types stained with a DNA dye is demonstrated using this technique. The integrated signal from bands of fluorescent microspheres is shown to be proportional to their initial concentration in suspension. Among the current generation of medical diagnostics are devices based on the principle of centrifuging a CD sized disk functionalized with microfluidics. These portable 'lab on a disk' devices are capable of conducting multiple assays directly from a blood sample, embodied by platforms developed by Gyros, Samsung, and Abaxis. [1,2] However, no centrifugal platform to date includes a differential white blood cell count, which is an important metric complimentary to diagnostic assays. Measuring the differential white blood cell count (the relative fraction of granulocytes, lymphocytes, and monocytes) is a standard medical diagnostic technique useful for identifying sepsis, leukemia, AIDS, radiation exposure, and a host of other conditions that affect the immune system. Several methods exist for measuring the relative white blood cell count including flow cytometry, electrical impedance, and visual identification from a stained drop of blood under a microscope. However, none of these methods is easily incorporated into a centrifugal microfluidic diagnostic platform.

  11. Statistical tests to compare motif count exceptionalities

    Full Text Available Abstract Background Finding over- or under-represented motifs in biological sequences is now a common task in genomics. Thanks to p-value calculation for motif counts, exceptional motifs are identified and represent candidate functional motifs. The present work addresses the related question of comparing the exceptionality of one motif in two different sequences. Just comparing the motif count p-values in each sequence is indeed not sufficient to decide if this motif is significantly more exceptional in one sequence compared to the other one. A statistical test is required. Results We develop and analyze two statistical tests, an exact binomial one and an asymptotic likelihood ratio test, to decide whether the exceptionality of a given motif is equivalent or significantly different in two sequences of interest. For that purpose, motif occurrences are modeled by Poisson processes, with a special care for overlapping motifs. Both tests can take the sequence compositions into account. As an illustration, we compare the octamer exceptionalities in the Escherichia coli K-12 backbone versus variable strain-specific loops. Conclusion The exact binomial test is particularly adapted for small counts. For large counts, we advise to use the likelihood ratio test which is asymptotic but strongly correlated with the exact binomial test and very simple to use.

    2012-12-01

    The box-counting algorithm is one of the most widely used methods for calculating the fractal dimension (FD). The FD has many image analysis applications in the biomedical field, where it has been used extensively to characterize a wide range of medical signals. However, computing the FD for large images, especially in 3D, is a time consuming process. In this paper we present a fast parallel version of the box-counting algorithm, which has been coded in CUDA for execution on the Graphic Processing Unit (GPU). The optimized GPU implementation achieved an average speedup of 28 times (28×) compared to a mono-threaded CPU implementation, and an average speedup of 7 times (7×) compared to a multi-threaded CPU implementation. The performance of our improved box-counting algorithm has been tested with 3D models with different complexity, features and sizes. The validity and accuracy of the algorithm has been confirmed using models with well-known FD values. As a case study, a 3D FD analysis of several brain tissues has been performed using our GPU box-counting algorithm.

    2011-05-01

    We generalize the binary quantum counting algorithm of Lesovik, Suslov, and Blatter [Phys. Rev. APLRAAN1050-294710.1103/PhysRevA.82.012316 82, 012316 (2010)] to higher counting bases. The algorithm makes use of qubits, qutrits, and qudits to count numbers in a base-2, base-3, or base-d representation. In operating the algorithm, the number ncounting task naturally leads to the shift operation and an algorithm based on the quantum Fourier transformation. We discuss possible implementations of the algorithm using quantum spin-d systems, d-well systems, and their emulation with spin-1/2 or double-well systems. We establish the analogy between our counting algorithm and the phase estimation algorithm and make use of the latter’s performance analysis in stabilizing our scheme. Applications embrace a quantum metrological scheme to measure voltage (an analog to digital converter) and a simple procedure to entangle multiparticle states.

    The expensive and technology limited setting of CD4 count testing is a major setback to the initiation of HAART in a resource limited country like Nigeria. Simple and inexpensive tools such as Hemoglobin (Hb) measurement and Total Lymphocyte Count (TLC) are recommended as substitute marker. In order to assess the correlations of these parameters with CD4 count, 100 "apparently healthy" male volunteers tested HIV positive aged ≥ 20 years but ≤ 40 years were recruited and from whom Hb, Hct, TLC and CD4 count were obtained. The correlation coefficients, R, the Nash-Sutcliffe Coefficient of Efficiency (CoE) and the p-values of the ANOVA model of Hb, Hct and TLC with CD4 count were assessed. The assessments show that there is no significant relationship of any of these parameters with CD4 count and the correlation coefficients are very weak. This study shows that Hb, Hct and TLC cannot be substitute for CD4 count as this might lead to certain individuals' deprivation of required treatment.

  20. To count or not to count: the effect of instructions on expecting a break in timing.

    Science.gov (United States)

    Gaudreault, Rémi; Fortin, Claudette

    2013-04-01

    When a break is expected during a time interval production, longer intervals are produced as the break occurs later during the interval. This effect of break location was interpreted as a result of distraction related to break expectancy in previous studies. In the present study, the influence of target duration and of instructions about chronometric counting strategies on the break location effect was examined. Using a strategy such as chronometric counting enhances the reliability of temporal processing, typically in terms of reduced variability, and could influence how timing is affected by break expectancy, especially when relatively long target durations are used. In two experiments, results show that time productions lengthened with increasing value of break location at various target durations and that variability was greater in the no-counting than in the counting instruction condition. More important, the break location effect was stronger in the no-counting than in the counting instruction condition. We conclude that chronometric counting orients attention toward timing processes, making them less likely to be disrupted by concurrent nontemporal processes.

    Full Text Available In this study, we analyzed the biogeographic patterns of the Chilean littoral fish fauna, including latitudinal trends in teleost and chondrichthyan fish species richness, their distribution range patterns, and their level of endemism, both to the Chilean coast and the Southeastern Pacific. We determined the number and percentage of fish taxa within four different groups based on their biogeographic affinities. This was done, both for teleost and chondrichthyan fishes, at the species, genus and family level. In order to recognise the existence of biogeographic regions, we applied cluster and ordination analyses to the distribution data, using objective bootstrapping techniques at the three taxonomic levels used. We found that littoral fish diversity remains fairly constant along the coast down to around 40º S, declining south of this latitude. We detected two biogeographic regions along the Chilean coast, with a break between them at 40º S. These results lend support to previously recognized biogeographic provinces or faunistic units. These two biogeographic regions are a reflection of the mixed origin of the Chilean littoral ichthyofauna, consisting of northern warm-temperate fishes of subtropical origin and southern cold-temperate fishes of subantarctic origin. While the percentage of fishes endemic to the Chilean coast is not high (18%, a large percentage of teleost species inhabiting Chilean littoral waters are endemic to the Southeastern Pacific (44%. Dispersal and evolutionary history, rather that other factors, seem to explain the observed patterns of distribution of this particular fish fauna. This study represents a necessary first step towards understanding the biogeography of Southeastern Pacific marine fishesEn este estudio, analizamos los patrones biogeográficos de los peces litorales chilenos, incluyendo las tendencias latitudinales en riqueza de especies de peces teleosteos y condrictios, sus rangos de distribución, y nivel de

    We present a microscopic index formula for the degeneracy of dyons in four-dimensional N=4 string theory. This counting formula is manifestly symmetric under the duality group, and its asymptotic growth reproduces the macroscopic Bekenstein-Hawking entropy. We give a derivation of this result in terms of the type II five-brane compactified on K3, by assuming that its fluctuations are described by a closed string theory on its world-volume. We find that the degeneracies are given in terms of the denominator of a generalized super Kac-Moody algebra. We also discuss the correspondence of this result with the counting of D-brane states.

    We use very deep near-infrared imaging data taken with Multi-Object InfraRed Camera and Spectrograph (MOIRCS) on the Subaru Telescope to investigate the number counts of Distant Red Galaxies (DRGs). We have observed a 4x7 arcmin^2 field in the Great Observatories Origins Deep Survey North (GOODS-N), and our data reach J=24.6 and K=23.2 (5sigma, Vega magnitude). The surface density of DRGs selected by J-K>2.3 is 2.35+-0.31 arcmin^-2 at K22 is smaller than that expected from the number counts at the brighter magnitude. The result indicates that while there are many bright galaxies at 222 suggest that the mass-dependent color distribution, where most of low-mass galaxies are blue while more massive galaxies tend to have redder colors, had already been established at that epoch.

    2017-03-01

    We introduce and experimentally implement a method for the detector calibration of photon-number-resolving time-bin multiplexing layouts based on the measured click statistics of superconducting nanowire detectors. In particular, the quantum efficiencies, the dark count rates, and the positive operator-valued measures of these measurement schemes are directly obtained with high accuracy. The method is based on the moments of the click-counting statistics for coherent states with different coherent amplitudes. The strength of our analysis is that we can directly conclude—on a quantitative basis—that the detection strategy under study is well described by a linear response function for the light-matter interaction and that it is sensitive to the polarization of the incident light field. Moreover, our method is further extended to a two-mode detection scenario. Finally, we present possible applications for such well-characterized detectors, such as sensing of atmospheric loss channels and phase sensitive measurements.

    We calculate the distribution of current fluctuations in two simple exclusion models. Although these models are classical, we recover even for small systems such as a simple or a double barrier, the same distibution of current as given by traditional formalisms for quantum mesoscopic conductors. Due to their simplicity, the full counting statistics in exclusion models can be reduced to the calculation of the largest eigenvalue of a matrix, the size of which is the number of internal configurations of the system. As examples, we derive the shot noise power and higher order statistics of current fluctuations (skewness, full counting statistics, ....) of various conductors, including multiple barriers, diffusive islands between tunnel barriers and diffusive media. A special attention is dedicated to the third cumulant, which experimental measurability has been demonstrated lately.

  10. Counting and Enumeration Problems with Bounded Treewidth

    Pichler, Reinhard; Rümmele, Stefan; Woltran, Stefan

    By Courcelle's Theorem we know that any property of finite structures definable in monadic second-order logic (MSO) becomes tractable over structures with bounded treewidth. This result was extended to counting problems by Arnborg et al. and to enumeration problems by Flum et al. Despite the undisputed importance of these results for proving fixed-parameter tractability, they do not directly yield implementable algorithms. Recently, Gottlob et al. presented a new approach using monadic datalog to close the gap between theoretical tractability and practical computability for MSO-definable decision problems. In the current work we show how counting and enumeration problems can be tackled by an appropriate extension of the datalog approach.

    Full Text Available Dispensing medications in a community pharmacy was a time-consuming operation. The pharmacist dispensed most prescriptions that were in tablet or capsule form with a simple tray and spatula. Many new medications were being developed by pharmaceutical manufacturers at an ever-increasing pace, and the prices of those medications were rising steeply. A typical community pharmacist was working longer hours and often forced to hire additional staff to handle increased workloads. This extra workload did not allow the time to focus on safety issues. This new factor led to the concept of using a machine to count medications. This paper introduces a design based on using microcontrollers for counting tablets and capsules . A production flow is build to automate the whole operations

    Full Text Available The current industry demand for dairy products with extended shelf life has resulted in new challenges for milk quality maintenance. The processing of milk with high bacterial counts compromises the quality and performance of industrial products. The study aimed to evaluate the total bacteria counts (TBC and somatic cell count (SCC in 768 samples of refrigerated raw milk, from 32 communal tanks. Samples were collected in the first quarter of 2010, 2011, 2012 and 2013 and analyzed by the Laboratory of Milk Quality - LQL. Results showed that 62.5%, 37.5%, 15.6% and 27.1% of the means for TBC in 2010, 2011, 2012 and 2013, respectively, were above the values established by legislation. However, we observed a significant reduction in the levels of total bacterial count (TBC in the studied periods. For somatic cell count, 100% of the means indicated values below 600.000 cells/mL, complying with the actual Brazilian legislation. The values found for the somatic cell count suggests the adoption of effective measures for the sanitary control of the herd. However, the results must be considered with caution as it highlights the need for quality improvements of the raw material until it achieves reliable results effectively.

    An improved method is provided for determining bacterial levels, especially in samples of aqueous physiological fluids. The method depends on the quantitative determination of bacterial adenosine triphosphate (ATP) in the presence of nonbacterial ATP. The bacterial ATP is released by cell rupture and is measured by an enzymatic bioluminescent assay. A concentration technique is included to make the method more sensitive. It is particularly useful where the fluid to be measured contains an unknown or low bacteria count.

With a total survey area > 100 arcmin2 and 1 sigma sensitivities of 3.92 and 0.82 mJy/beam at 450 and 850 micron respectively, we find a secure sample of 20 sources at 450 micron and 26 sources at 850 micron with a signal-to-noise ratio > 4. Using the latest lensing model of A370 and Monte Carlo simulations, we derive the number counts at both wavelengths. The 450 micron number counts probe a factor of four deeper than the counts recently obtained from the Herschel Space Telescope at similar wavelengths, and we estimate that ~47-61% of the 450 micron extragalactic background light (EBL) resolved into individual sources with 450 micron fluxes greater than 4.5 mJy. The faint 450 micron sources in the 4 sigma sample have positional accuracies of 3 arcseconds, while brighter sources (signal-to-noise > 6 sigma) are good to 1.4 arcseconds. Using the deep radio map (1 sigma ~ 6 uJy) we find tha...

    Full Text Available In the present study, we experimentally tested the role of hand motor circuits in simple-arithmetic strategies. Educated adults solved simple additions (e.g., 8+3 or simple subtractions (e.g., 11–3 while they were required to retrieve the answer from long-term memory (e.g., knowing that 8+3 = 11, to transform the problem by making an intermediate step (e.g., 8+3 = 8+2+1 = 10+1 = 11 or to count one-by-one (e.g., 8+3 = 8…9…10…11. During the process of solving the arithmetic problems, the experimenter did or did not move the participants’ hand on a 4-point matrix. The results show that passive hand movements disrupted the counting strategy while leaving the other strategies unaffected. This pattern of results is in agreement with a procedural account, showing that the involvement of hand motor circuits in adults’ mathematical abilities is reminiscent of finger counting during childhood.

    The article is dedicated to the presentation of a vision-based system for road vehicle counting and classification. The system is able to achieve counting with a very good accuracy even in difficult scenarios linked to occlusions and/or presence of shadows. The principle of the system is to use already installed cameras in road networks without any additional calibration procedure. We propose a robust segmentation algorithm that detects foreground pixels corresponding to moving vehicles. First, the approach models each pixel of the background with an adaptive Gaussian distribution. This model is coupled with a motion detection procedure, which allows correctly location of moving vehicles in space and time. The nature of trials carried out, including peak periods and various vehicle types, leads to an increase of occlusions between cars and between cars and trucks. A specific method for severe occlusion detection, based on the notion of solidity, has been carried out and tested. Furthermore, the method developed in this work is capable of managing shadows with high resolution. The related algorithm has been tested and compared to a classical method. Experimental results based on four large datasets show that our method can count and classify vehicles in real time with a high level of performance (>98%) under different environmental situations, thus performing better than the conventional inductive loop detectors.

In order to understand the nature of the sourcescontributing to the CIB, and to explain deep source counts at otherwavelengths, we have developed a phenomenological model, which constrains in asimple way the luminosity function evolution with redshift, and fits all theexisting deep source counts from the mid-infrared to the submillimetre range.Images, materials and papers available on the FIRBACK web:http://wwwfirback.ias.u-psud.fr wwwfirback.ias.u-psud.fr

    Full Text Available Objetivos. Evaluar el estado nutricional, los patrones alimentarios y de actividad física en escolares del Cercado deLima. Materiales y métodos. Estudio descriptivo transversal. La muestra incluyó escolares del 1.° a 4.° grado de primaria de cuatro instituciones educativas públicas ubicadas en el Cercado de Lima. Las variables de estudio fueron el estado nutricional, nivel de hemoglobina, los patrones de consumo de alimentos y de actividad física. Se calcularon los porcentajes de las variables cualitativas y medidas de tendencia central para las cuantitativas, en el análisis bivariado se aplicó la prueba t y la prueba de chi cuadrado para analizar las diferencias según sexo. Resultados. De 824 escolares incluidos en el estudio, se encontró un 24% con obesidad, mientras que el sobrepeso afectó al 22%, la proporción de talla baja fue de 5% y la de anemia fue 11,9%, en todos los casos no hubo diferencias significativas según sexo. Más del 40% de escolares consumían 2 o más veces a la semana galletas saladas, jugos envasados y/o gaseosas. Además, el 28% de escolares eran sedentarios, encontrándose diferencias significativas según sexo (p<0,05. Conclusiones. La obesidad es un problema vigente, con mayor frecuencia que el sobrepeso y que juntos afectan a casi el 50% de los escolares del estudio. Asimismo, se evidencia que existen patrones de sedentarismo y consumo frecuente de alimentos con alto contenido de azúcar, sal y/o grasas.

    Full Text Available El flujo conductual en el fútbol esconde un orden que es importante conocer para comprender mejor el juego e intervenir positivamente en el proceso de entrenamiento. En el presente estudio se pretende desarrollar y aplicar un instrumento de observación ad hoc que permita estimar patrones conductuales del proceso ofensivo en el fútbol, con la intención de modelar la eficacia de los equipos. Después de la elaboración de un protocolo de observación y de haber sido superada la prueba de fiabilidad de la codificación (concordancia intra-observador, fueron codificados 11 partidos de Fútbol correspondientes a la segunda fase del Campeonato del Mundo de Fútbol Corea-Japón 2002, de los cuales fueron registrados 941 procesos ofensivos y un total de 9.273 multieventos. Para el tratamento y análisis de los datos se recurrió al Software SDIS-GSEQ de Bakeman y Quera, debido a su especificidad para analizar eventos múltiples. Los resultados de este análisis permitieron estimar patrones de conducta del proceso ofensivo en el fútbol y mapas conductuales que reflejan las transiciones y relaciones de activación o inhibición entre las diferentes categorías del instrumento de observación. Se observó que para la mayoría de las conductas elevadas a condición de conducta criterio, los patrones conductuales son muy cortos. Fue posible determinar patrones de conducta y relaciones activadoras de unas conductas en relación a otras que le anteceden o suceden inmediatamente a continuación, del cual resultan transiciones positivas o negativas para la di-námica del juego, aún a una mayor distancia, esa relación activadora es más difícil de prever, volviéndose más fuerte el factor suerte o casualidad. Se concluye que durante el proceso ofensivo existe uma nítida diferenciación espacial, interaccional y comportamental que dio origen a una división del proceso ofensivo en cuatro fases distintas: 1 inicio del proceso ofensivo; 2 construcción del

    Grossmann, T

    1981-06-01

    On an altar-piece of the Gothic mercy-seat altar in the hospital church of Bad Aussee, made in 1449, Saint Ottilia, the patron saint of eye sufferers, is depicted with a crab's pincer, an attribute hitherto unknown. In the Middle Ages it was customary to put crab-eyes, which are calcium formations in the stomach of the crab, into the eyes of individuals to remove foreign bodies. As these crab-eyes are too small to be seen at any distance, the author takes the view that another typical and well-known part of the crab's body, more suitable for the representation, was used.

    Full Text Available La conducta agonística territorial en machos de la especie Phenacosaurus heterodermus presenta amplia variabilidad intraindividual e interindividual en los patrones de comportamiento observados. Por medio de una metodología de observación, se lograron caracterizar patrones de conducta individuales y secuenciales y acciones más complejas de exhibiciones simultáneas. El cabeceo se tomó como el patrón básico de dicho comportamiento, siendo cuantitativamente el más importante.  Se comparó la caracterización de los patrones de conducta agresiva con aquellos presentes en el cortejo, observándose gran similitud con éstos. The territorial aggressive behavior in males of the species Phenacosaurus heterodermus presents a wide range of variation within the individual and among individuals in the patterns of behavior observed. By means of methods of observation it was possible to characterize behavioral patterns of individual and sequence displays, and more complex actions of simultaneous exhibitions. The head bob was taken as the basic pattern for this behavior, being quantitatively the most important.  These aggressive patterns were compared with those present in courtship, of the same species, observing great similarities between them.

    Full Text Available La familia Arecaceae es rica en especies, principalmente en el trópico, y constituye una fuente de recursos para la subsistencia de sus pobladores. En el presente trabajo se estudió la riqueza, diversidad, composición y patrones de uso de la familia Arecaceae en tres localidades de la cuenca media del río Atrato en el Chocó, Colombia, con el fin de obtener información que permita su conservación y uso sostenible. Se registraron 29 especies en 18 géneros, siendo Bactris 24.13 y Wettinia 10.34 los géneros más ricos en especies. El Buey mostró más especies y géneros 23 especies, 17 géneros que Beté 15 y 10 respectivamente y Tanguí 14 y 11 respectivamente. La similitud florística entre localidades fue menor al 45. Las especies con mayor peso ecológico y valor de uso fueron: Euterpe oleracea Mart., Oenocarpus bataua Mart., Attalea allennii H.E. Moore, Manicaria saccifera Gaertn., Bactris gassipaes Kunth y Wettinia quinaria O.F.Cook y Doyle R. Bernal. Las categorías de uso con mayor riqueza de especies e importancia cultural fueron: construcción, alimento y uso artesanal; y los órganos más usados fueron tallos y frutos. Los resultados de este trabajo demuestran que el Atrato Medio posee alta riqueza y diversidad de especies de palmas en un contexto regional y nacional. Sin embargo, la relación entre el número de uso y la importancia ecológica de la especie depende de la localidad, lo que indica que la importancia socio-cultural de la especie puede variar entre grupos humanos que comparten una misma cultura o región biogeográfica. Se publicarán estudios a futuro para determinar el papel del tipo de órgano utilizado como materia prima en la demografía y dinámica ecológica de las poblaciones de palma en el Chocó y otras regiones del Neotrópico.

  3. Counting, Measuring And The Semantics Of Classifiers

    Directory of Open Access Journals (Sweden)

    Susan Rothstein

    2010-12-01

    Full Text Available This paper makes two central claims. The first is that there is an intimate and non-trivial relation between the mass/count distinction on the one hand and the measure/individuation distinction on the other: a (if not the defining property of mass nouns is that they denote sets of entities which can be measured, while count nouns denote sets of entities which can be counted. Crucially, this is a difference in grammatical perspective and not in ontological status. The second claim is that the mass/count distinction between two types of nominals has its direct correlate at the level of classifier phrases: classifier phrases like two bottles of wine are ambiguous between a counting, or individuating, reading and a measure reading. On the counting reading, this phrase has count semantics, on the measure reading it has mass semantics.ReferencesBorer, H. 1999. ‘Deconstructing the construct’. In K. Johnson & I.

    2015-02-01

    Full Text Available We describe the R package geoCount for the analysis of geostatistical count data. The package performs Bayesian analysis for the Poisson-lognormal and binomial-logitnormal spatial models, which are subclasses of the class of generalized linear spatial models proposed by Diggle, Tawn, and Moyeed (1998. The package implements the computational intensive tasks in C++ using an R/C++ interface, and has parallel computation capabilities to speed up the computations. geoCount also implements group updating, Langevin- Hastings algorithms and a data-based parameterization, algorithmic approaches proposed by Christensen, Roberts, and Sko ?ld (2006 to improve the efficiency of the Markov chain Monte Carlo algorithms. In addition, the package includes functions for simulation and visualization, as well as three geostatistical count datasets taken from the literature. One of those is used to illustrate the package capabilities. Finally, we provide a side-by-side comparison between geoCount and the R packages geoRglm and INLA.

  5. Bibliometric Approach to Research Assessment: Publication Count, Citation Count, & Author Rank

    Directory of Open Access Journals (Sweden)

    Yang, Kiduk

    2013-03-01

    Full Text Available We investigated how bibliometric indicators such as publication count and citation count affect the assessment of research performance by computing various bibliometric scores of the works of Korean LIS faculty members and comparing the rankings by those scores. For the study data, we used the publication and citation data of 159 tenure-track faculty members of Library and Information Science departments in 34 Korean universities. The study results showed correlation between publication count and citation count for authors with many publications but the opposite evidence for authors with few publications. The study results suggest that as authors publish more and more work, citations to their work tend to increase along with publication count. However, for junior faculty members who have not yet accumulated enough publications, citations to their work are of great importance in assessing their research performance. The study data also showed that there are marked differences in the magnitude of citations between papers published in Korean journals and papers published in international journals.

  6. A mind you can count on: validating breath counting as a behavioral measure of mindfulness

    Directory of Open Access Journals (Sweden)

    Daniel B Levinson

    2014-10-01

    Full Text Available Mindfulness practice of present moment awareness promises many benefits, but has eluded rigorous behavioral measurement. To date, research has relied on self-reported mindfulness or heterogeneous mindfulness trainings to infer skillful mindfulness practice and its effects. In four independent studies with over 400 total participants, we present the first construct validation of a behavioral measure of mindfulness, breath counting. We found it was reliable, correlated with self-reported mindfulness, differentiated long-term meditators from age-matched controls, and was distinct from sustained attention and working memory measures. In addition, we employed breath counting to test the nomological network of mindfulness. As theorized, we found skill in breath counting associated with more meta-awareness, less mind wandering, better mood, and greater nonattachment (i.e. less attentional capture by distractors formerly paired with reward. We also found in a randomized online training study that 4 weeks of breath counting training improved mindfulness and decreased mind wandering relative to working memory training and no training controls. Together, these findings provide the first evidence for breath counting as a behavioral measure of mindfulness.

  7. Short communication: Repeatability of differential goat bulk milk culture and associations with somatic cell count, total bacterial count, and standard plate count.

    Koop, G; Dik, N; Nielen, M; Lipman, L J A

    2010-06-01

    The aims of this study were to assess how different bacterial groups in bulk milk are related to bulk milk somatic cell count (SCC), bulk milk total bacterial count (TBC), and bulk milk standard plate count (SPC) and to measure the repeatability of bulk milk culturing. On 53 Dutch dairy goat farms, 3 bulk milk samples were collected at intervals of 2 wk. The samples were cultured for SPC, coliform count, and staphylococcal count and for the presence of Staphylococcus aureus. Furthermore, SCC (Fossomatic 5000, Foss, Hillerød, Denmark) and TBC (BactoScan FC 150, Foss) were measured. Staphylococcal count was correlated to SCC (r=0.40), TBC (r=0.51), and SPC (r=0.53). Coliform count was correlated to TBC (r=0.33), but not to any of the other variables. Staphylococcus aureus did not correlate to SCC. The contribution of the staphylococcal count to the SPC was 31%, whereas the coliform count comprised only 1% of the SPC. The agreement of the repeated measurements was low. This study indicates that staphylococci in goat bulk milk are related to SCC and make a significant contribution to SPC. Because of the high variation in bacterial counts, repeated sampling is necessary to draw valid conclusions from bulk milk culturing.

    McNutt, M. K.

    2014-12-01

    Despite the fact that many US researchers face increasing competition in chasing after federal support that has not kept pace with inflation, the good news is that private support is on the rise. A growing number of wealthy individuals are investing in research areas that reflect their deeply-held passions as their personal philanthropy. They typically are unafraid to take risks, abhor bureaucracy, and nimbly cross disciplinary boundaries. Many put their personal imprimatur on the direction and operation of the ventures that bear their names. However, private funding is not a replacement for federal funding. It is not coordinated. Absent adequate federal support, gaps can develop: between and within fields, in the balance of exploratory, basic, applied, and translational research, and in the support of scientific talent at different levels of training or institutions of different types. The private share remains small and cannot compensate for significant losses in federal dollars. For these reasons, it is important that scientists and philanthropists make the case to our political leadership that private funding does not replace public support. Private funding is and always has been a huge boon to the scientific enterprise. Universities and researchers have for more than a century been successfully merging public and private funds to profit from the advantages of each funding source, accelerate scientific discovery, and benefit humanity. Given the many causes that could engage the attention of these philanthropists, we are fortunate that so many have chosen to give back to society through the geosciences.

  3. Counting Trees in Supersymmetric Quantum Mechanics

    2015-01-01

    We study the supersymmetric ground states of the Kronecker model of quiver quantum mechanics. This is the simplest quiver with two gauge groups and bifundamental matter fields, and appears universally in four-dimensional N=2 systems. The ground state degeneracy may be written as a multi-dimensional contour integral, and the enumeration of poles can be simply phrased as counting bipartite trees. We solve this combinatorics problem, thereby obtaining exact formulas for the degeneracies of an infinite class of models. We also develop an algorithm to compute the angular momentum of the ground states, and present explicit expressions for the refined indices of theories where one rank is small.

    Many cold atom experiments rely on precise atom number detection, especially in the context of quantum-enhanced metrology where effects at the single particle level are important. Here, we investigate the limits of atom number counting via resonant fluorescence detection for mesoscopic samples of trapped atoms. We characterize the precision of these fluorescence measurements beginning from the single-atom level up to more than one thousand. By investigating the primary noise sources, we obtain single-atom resolution for atom numbers as high as 1200. This capability is an essential prerequisite for future experiments with highly entangled states of mesoscopic atomic ensembles.

    Neutron coincidence counting is a widely adopted nondestructive assay (NDA) technique used in nuclear safeguards to measure the mass of nuclear material in samples. Nowadays, most neutron-counting systems are based on the original-shift-register technology, like the (ordinary or multiplicity) Shift-Register Analyser. The analogue signal from the He-3 tubes is processed by an amplifier/single channel analyser (SCA) producing a train of TTL pulses that are fed into an electronic unit that performs the time- correlation analysis. Following the suggestion of the main inspection authorities (IAEA, Euratom and the French Ministry of Industry), several research laboratories have started to study and develop prototypes of neutron-counting systems with PC-based processing. Collaboration in this field among JRC, IRSN and LANL has been established within the framework of the ESARDA-NDA working group. Joint testing campaigns have been performed in the JRC PERLA laboratory, using different equipment provided by the three partners. One area of development is the use of high-speed PCs and pulse acquisition electronics that provide a time stamp (LIST-Mode Acquisition) for every digital pulse. The time stamp data can be processed directly during acquisition or saved on a hard disk. The latter method has the advantage that measurement data can be analysed with different values for parameters like predelay and gate width, without repeating the acquisition. Other useful diagnostic information, such as die-away time and dead time, can also be extracted from this stored data. A second area is the development of 'virtual instruments.' These devices, in which the pulse-processing system can be embedded in the neutron counter itself and sends counting data to a PC, can give increased data-acquisition speeds. Either or both of these developments could give rise to the next generation of instrumentation for improved practical neutron-correlation measurements. The paper will

    We observe that a class of quarter-BPS dyons in mathcal{N} = 4 theories with charge vector ( Q, P) and with nontrivial values of the arithmetic duality invariant I := gcd( Q∧ P) are nonperturbative in one frame but perturbative in another frame. This observation suggests a test of the recently computed nonperturbative partition functions for dyons with nontrivial values of the arithmetic invariant. For all values of I, we show that the nonperturbative counting yields vanishing indexed degeneracy for this class of states everywhere in the moduli space in precise agreement with the perturbative result.

    Clusters of galaxies may contain radio sources if they still experience successive mergers at present. This has been confirmed by radio observations that about 30% of nearby clusters possess radio halos. We present a theoretical prediction of radio cluster counts using a semi-analytic approach which incorporates the empirical correlation between radio power and dynamical mass of clusters, and the cluster mass function described by the Press-Schechter formalism. The total population of radio clusters over the whole sky and their redshift distribution are given.

    Full Text Available En este trabajo se analiza la representación de los aliens en un grupo reciente de franquicias, comunicaciones periodísticas y transmedia a fin de describir patrones recurrentes y de interpretarlos en el contexto cultural actual. La hipótesis es la preeminencia de la imagen esotérica de los aliens en ellas, como resultado de un hipotexto mitológico fruto de un folk procesado y actualizado en los transmedia. La comunicación mediática sería el canal de difusión de estos neomitos. Para ello, se parte como método del análisis comparativo de diferentes franquicias para detectar patrones narratológicos recurrentes. Las conclusiones conciernen al leitmotiv de las teorías conspiracionistas e interpretaciones milenaristas, ecologistas o neoevemeristas, según su recepción en los distintos grupos. Los símbolos codificados son una hibridación y reactualización de mitos tradicionales, en la dirección esotérica indicada, que proponen nuevas lecturas a cuestiones como el origen de la vida, el medio ambiente o el control de los recursos, configurando así una

    Vehicle counting is used by the government to improve roadways and the flow of traffic, and by private businesses for purposes such as determining the value of locating a new store in an area. A vehicle count can be performed manually or automatically. Manual counting requires an individual to be on-site and tally the traffic electronically or by hand. However, this can lead to miscounts due to factors such as human error A common form of automatic counting involves pneumatic tubes, but pneumatic tubes disrupt traffic during installation and removal, and can be damaged by passing vehicles. Vehicle counting can also be performed via the use of a camera at the count site recording video of the traffic, with counting being performed manually post-recording or using automatic algorithms. This paper presents a low-cost procedure to perform automatic vehicle counting using remote video cameras with an automatic counting algorithm. The procedure would utilize a Raspberry Pi micro-computer to detect when a car is in a lane, and generate an accurate count of vehicle movements. The method utilized in this paper would use background subtraction to process the images and a machine learning algorithm to provide the count. This method avoids fatigue issues that are encountered in manual video counting and prevents the disruption of roadways that occurs when installing pneumatic tubes

    Background characterization at Homestake is an ongoing project crucial to the experiments located there. From neutrino physics to WIMP detection, low-background materials and their screening require highly sensitive detectors. Naturally, shielding is needed to lower ``noise'' in these detectors. Because of its vast depth, Homestake will be effective in shielding against cosmic-ray radiation. This means little, however, if radiation from materials used still interferes. Specifically, our group is working on designing the first low-background counting facility at the Homestake mine. Using a high-purity germanium crystal detector from ORTEC, measurements will be taken within a shield that is made to specifically account for radiation underground and fits the detector. Currently, in the design, there is a layer of copper surrounded by an intricate stainless steel casing, which will be manufactured air tight to accommodate for nitrogen purging. Lead will surround the stainless steel shell to further absorb gamma rays. A mobile lift system has been designed for easy access to the detector. In the future, this project will include multiple testing stations located in the famous Davis Cavern where future experiments will have the ability to use the site as an efficient and accurate counting facility for their needs (such as measuring radioactive isotopes in materials). Overall, this detector (and its shield system) is the beginning of a central testing facility that will serve Homestake's scientific community.

  9. Maximal subbundles, quot schemes, and curve counting

    Let $E$ be a rank 2, degree $d$ vector bundle over a genus $g$ curve $C$. The loci of stable pairs on $E$ in class $2[C]$ fixed by the scaling action are expressed as products of $\\Quot$ schemes. Using virtual localization, the stable pairs invariants of $E$ are related to the virtual intersection theory of $\\Quot E$. The latter theory is extensively discussed for an $E$ of arbitrary rank; the tautological ring of $\\Quot E$ is defined and is computed on the locus parameterizing rank one subsheaves. In case $E$ has rank 2, $d$ and $g$ have opposite parity, and $E$ is sufficiently generic, it is known that $E$ has exactly $2^g$ line subbundles of maximal degree. Doubling the zero section along such a subbundle gives a curve in the total space of $E$ in class $2[C]$. We relate this count of maximal subbundles with stable pairs/Donaldson-Thomas theory on the total space of $E$. This endows the residue invariants of $E$ with enumerative significance: they actually \\emph{count} curves in $E$.

    2008-06-01

    Full Text Available The classical Poisson, geometric and negative binomial regression models for count data belong to the family of generalized linear models and are available at the core of the statistics toolbox in the R system for statistical computing. After reviewing the conceptual and computational features of these methods, a new implementation of hurdle and zero-inflated regression models in the functions hurdle( and zeroinfl( from the package pscl is introduced. It re-uses design and functionality of the basic R functions just as the underlying conceptual tools extend the classical models. Both hurdle and zero-inflated model, are able to incorporate over-dispersion and excess zeros-two problems that typically occur in count data sets in economics and the social sciences—better than their classical counterparts. Using cross-section data on the demand for medical care, it is illustrated how the classical as well as the zero-augmented models can be fitted, inspected and tested in practice.

    The first thing a "marketing guy" asks the digital camera engineer is "how many pixels does it have, for we need as many mega pixels as possible since the other guys are killing us with their "umpteen" mega pixel pocket sized digital cameras. And so it goes until the pixels get smaller and smaller in order to inflate the pixel count in the never-ending pixel-wars. These small pixels just are not very good. The truth of the matter is that the most important feature of digital cameras in the last five years is the automatic motion control to stabilize the image on the sensor along with some very sophisticated image processing. All the rest has been hype and some "cool" design. What is the future for digital imaging and what will drive growth of camera sales (not counting the cell phone cameras which totally dominate the market in terms of camera sales) and more importantly after sales profits? Well sit in on the Dark Side of Color and find out what is being done to increase the after sales profits and don't be surprised if has been done long ago in some basement lab of a photographic company and of course, before its time.

  12. Signatures of synchrony in pairwise count correlations

    Full Text Available Concerted neural activity can reflect specific features of sensory stimuli or behavioral tasks. Correlation coefficients and count correlations are frequently used to measure correlations between neurons, design synthetic spike trains and build population models. But are correlation coefficients always a reliable measure of input correlations? Here, we consider a stochastic model for the generation of correlated spike sequences which replicate neuronal pairwise correlations in many important aspects. We investigate under which conditions the correlation coefficients reflect the degree of input synchrony and when they can be used to build population models. We find that correlation coefficients can be a poor indicator of input synchrony for some cases of input correlations. In particular, count correlations computed for large time bins can vanish despite the presence of input correlations. These findings suggest that network models or potential coding schemes of neural population activity need to incorporate temporal properties of correlated inputs and take into consideration the regimes of firing rates and correlation strengths to ensure that their building blocks are an unambiguous measures of synchrony.

  13. Language and counting: Some recent results

    It has long been recognised that the language of mathematics is an important variable in the learning of mathematics, and there has been useful work in isolating and describing the linkage. Steffe and his co-workers at Georgia, for example, (Steffe, von Glasersfeld, Richardson and Cobb, 1983) have suggested that young children may construct verbal countable items to count objects which are hidden from their view. Although there has been a surge of research interest in counting and early childhood mathematics, and in cultural differences in mathematics attainment, there has been little work reported on the linkage between culture as exemplified by language, and initial concepts of numeration. This paper reports on some recent clinical research with kindergarten children of European and Asian background in Australia and America. The research examines the influence that number naming grammar appears to have on young children's understandings of two-digit numbers and place value. It appears that Transparent Standard Number Word Sequences such as Japanese, Chinese and Vietnamese which follow the numerical representation pattern by naming tens and units in order ("two tens three"), may be associated with distinctive place value concepts which may support sophisticated mental algorithms.

    For the SPECTRAP experiment at GSI, Germany, a detector system with single-photon counting capability operating in the wavelength region from 300 nm up to 1100 nm has been developed at the University of Muenster. The detector system utilises a silicon avalanche photo diode (APD) cooled to liquid nitrogen temperatures and operated near the breakdown voltage to obtain high gain values. While the current setup uses a 2 x 2 mm{sup 2} APD (type RMD S0223), it would be advantageous to have a larger active area for easier adjustment of the experiment optics. On the other hand a larger active area is accompanied by increased thermal noise which might harm the photon counting performance of the device. The characterization of a 8 x 8 mm{sup 2} APD (RMD S0814) is the subject of this poster. Furthermore a signal analysis software was developed to supress noise signals, e.g. caused by microphonic effects. The software processes signal waveforms recorded by a Flash ADC and should allow for a lower trigger threshold and thus higher detection efficiency.

  15. Sampling site matters when counting lymphocyte subpopulations.

    Full Text Available Clinical and scientific work routinely relies on antecubital venipunctures for hematological, immunological or other analyses on blood. This study tested the hypothesis that antecubital veins can be considered to be a good proxy for other sampling sites. Using a hematocytometer and a flow cytometer, we analyzed the cell counts from samples coming from the radial artery, the dorsal hand veins and the antecubital veins from 18 volunteers. Most surprisingly, we identified the greatest difference not to exist between arterial and venous circulation, but between the distal (radial artery & dorsal hand veins and proximal (antecubital veins sampling sites. Naïve T cells had a higher cell count distally compared to proximally and the reverse was true for effector memory T cells. Despite these differences there were high correlations between the different sampling sites, which partially supports our initial hypothesis. Our findings are crucial for the future design and interpretation of immunological research, and for clinical practice. Furthermore, our results suggest a role for interval lymph nodes in the trafficking of lymphocytes.

    There are few reports of pollen count and identification in Mexico; therefore, it is important to generate more information on the subject. This study was designed to describe the prevalence of pollen in the city of Monterrey, Mexico, during the year 2004. Atmospheric pollen was collected with a Hirst air sampler, with an airflow of 10 L/minute during 2004. Pollen was identified with light microscopy; the average monthly pollen count as well as total was calculated from January 2004 to January 2005. The months with the highest concentration of pollen were February and March (289 and 142 grains/m(3) per day, respectively), and July and November had the lowest concentration (20 and 11 grains/m(3) per day, respectively). Most of the pollen recollected corresponded to tree pollen (72%). Fraxinus spp had the highest concentration during the year (19 grains/m(3) per day; 27.5% of the total concentration of pollen). Tree pollen predominated from January through March; with Fraxinus spp, Morus spp, Celtis spp, Cupressus spp, and Pinus spp as the most important. Weed pollen predominated in May, June, and December and the most frequently identified, were Amaranthaceae/Chenopodiaceae, Ambrosia spp, and Parietaria spp. The highest concentration of grass pollen was reported during the months of May, June, September, October, and December with Gramineae/Poaceae predominating. Tree pollen was the most abundant during the year, with the ash tree having the highest concentration. Weed and grass pollen were perennial with peaks during the year.

    We present a new and unique measurement of the branching fractions of b hadrons to states with 0, 1, and 2 open charm hadrons, using a sample of 350,000 hadronic Z0 decays collected during the SLD/SLC 97–98 run. The analysis takes advantage of the excellent vertexing resolution of the VXD3, a pixel-based CCD vertex detector, which allows the separation of B and cascade D decay vertices. A fit of the vertex count and the decay length distributions to distribution shapes predicted by Monte Carlo simulation allows the extraction of the inclusive branching fractions. We measure: BRB→0D X=3.7±1.1 stat±2.1 syst% BRB→2D X=17.9±1.4 stat±3.3 syst% where B, and D represent mixtures of open b and open c hadrons. The corresponding charm count, Nc = 1.188 ± 0.010 ± 0.040 ± 0.006 is consistent with previous measurement averages but slightly closer to theoretical expectations.

    We show that the gravitational wave source counts distribution can test how gravitational radiation propagates on cosmological scales. This test does not require obtaining redshifts for the sources. If the signal-to-noise ratio (ρ) from a gravitational wave source is proportional to the strain then it falls as {R}-1, thus we expect the source counts to follow {{d}}{N}/{{d}}ρ \\propto {ρ }-4. However, if gravitational waves decay as they propagate or propagate into other dimensions, then there can be deviations from this generic prediction. We consider the possibility that the strain falls as {R}-γ , where γ =1 recovers the expected predictions in a Euclidean uniformly-filled Universe, and forecast the sensitivity of future observations to deviations from standard General Relativity. We first consider the case of few objects, seven sources, with a signal-to-noise from 8 to 24, and impose a lower limit on γ, finding γ \\gt 0.33 at 95% confidence level. The distribution of our simulated sample is very consistent with the distribution of the trigger events reported by Advanced LIGO. Future measurements will improve these constraints: with 100 events, we estimate that γ can be measured with an uncertainty of 15%. We generalize the formalism to account for a range of chirp masses and the possibility that the signal falls as {exp}(-R/{R}0)/{R}γ .

    The Great World Wide Star Count is an international citizen science event encouraging everyone, astronomers and non-astronomers alike, to measure their local light pollution and report their observations online. This project is designed to raise awareness about light pollution as well as encourage learning in astronomy. Utilizing the international networking capabilities of Windows to the Universe, Star Count has engaged over 31,000 individuals from 64 countries and all 7 continents in its first 3 years. Data collection and online reporting is designed to be simple and user-friendly for citizen scientists of all ages. The collected data is available online in a variety of formats for use by students, teachers and scientists worldwide to assess how the quality of the night sky varies around the world. This session will share our results and demonstrate how students and scientists worldwide can explore and analyze the results from 2007—2010. We will discuss how the project team planned and executed the project in such a way that non-astronomers were able to make valid and useful contributions.

    We show that the gravitational wave source counts distribution can test how gravitational radiation propagates on cosmological scales. This test does not require obtaining redshifts for the sources. If the signal-to-noise from a gravitational wave source is proportional to the strain then it falls as $R^{-1}$, thus we expect the source counts to follow $dN/dS \\propto S^{-4}$. However, if gravitational waves decay as they propagate or can propagate into other dimensions, then there can be deviations from this generic prediction. We consider the possibility that the signal-to-noise falls as $R^{-\\gamma}$, where $\\gamma=1$ recovers the expected predictions in a Euclidean uniformly-filled universe. We forecast the sensitivity of future observations in constraining gravitational wave physics using this method by simulating sources distributed over a finite range of signal-to-noise.

  2. Photon Counting Using Edge-Detection Algorithm

    Gin, Jonathan W.; Nguyen, Danh H.; Farr, William H.

    2010-01-01

    New applications such as high-datarate, photon-starved, free-space optical communications require photon counting at flux rates into gigaphoton-per-second regimes coupled with subnanosecond timing accuracy. Current single-photon detectors that are capable of handling such operating conditions are designed in an array format and produce output pulses that span multiple sample times. In order to discern one pulse from another and not to overcount the number of incoming photons, a detection algorithm must be applied to the sampled detector output pulses. As flux rates increase, the ability to implement such a detection algorithm becomes difficult within a digital processor that may reside within a field-programmable gate array (FPGA). Systems have been developed and implemented to both characterize gigahertz bandwidth single-photon detectors, as well as process photon count signals at rates into gigaphotons per second in order to implement communications links at SCPPM (serial concatenated pulse position modulation) encoded data rates exceeding 100 megabits per second with efficiencies greater than two bits per detected photon. A hardware edge-detection algorithm and corresponding signal combining and deserialization hardware were developed to meet these requirements at sample rates up to 10 GHz. The photon discriminator deserializer hardware board accepts four inputs, which allows for the ability to take inputs from a quadphoton counting detector, to support requirements for optical tracking with a reduced number of hardware components. The four inputs are hardware leading-edge detected independently. After leading-edge detection, the resultant samples are ORed together prior to deserialization. The deserialization is performed to reduce the rate at which data is passed to a digital signal processor, perhaps residing within an FPGA. The hardware implements four separate analog inputs that are connected through RF connectors. Each analog input is fed to a high-speed 1

  3. Optimal allocation of point-count sampling effort

    Both unlimited and fixedradius point counts only provide indices to population size. Because longer count durations lead to counting a higher proportion of individuals at the point, proper design of these surveys must incorporate both count duration and sampling characteristics of population size. Using information about the relationship between proportion of individuals detected at a point and count duration, we present a method of optimizing a pointcount survey given a fixed total time for surveying and travelling between count points. The optimization can be based on several quantities that measure precision, accuracy, or power of tests based on counts, including (1) meansquare error of estimated population change; (2) mean-square error of average count; (3) maximum expected total count; or (4) power of a test for differences in average counts. Optimal solutions depend on a function that relates count duration at a point to the proportion of animals detected. We model this function using exponential and Weibull distributions, and use numerical techniques to conduct the optimization. We provide an example of the procedure in which the function is estimated from data of cumulative number of individual birds seen for different count durations for three species of Hawaiian forest birds. In the example, optimal count duration at a point can differ greatly depending on the quantities that are optimized. Optimization of the mean-square error or of tests based on average counts generally requires longer count durations than does estimation of population change. A clear formulation of the goals of the study is a critical step in the optimization process.

    Introduction. An absolute lymphocyte count is commonly used as an alternative to a CD4 count to determine initiation of antiretroviral therapy for HIV-infected individuals in Fiji when a CD4 count is unavailable. Methods. We conducted a retrospective analysis of laboratory results of HIV-infected individuals registered at all HIV clinics in Fiji. Results. Paired absolute lymphocyte and CD4 counts were available for 101 HIV-infected individuals, and 96% had a CD4 count of ≤500 cells/mm(3). Correlation between the counts in individuals was poor (Spearman rank correlation r = 0.5). No absolute lymphocyte count could be determined in this population as a suitable surrogate for a CD4 count of either 350 cells/mm(3) or 500 cells/mm(3). The currently used absolute lymphocyte count of ≤2300 cells/μL had a positive predictive value of 87% but a negative predictive value of only 17% for a CD4 of ≤350 cells/mm(3) and if used as a surrogate for a CD4 of ≤500 cells/mm(3) it would result in all HIV-infected individuals receiving ART including those not yet eligible. Weight, CD4 count, and absolute lymphocyte count increased significantly at 3 months following ART initiation. Conclusions. Our findings do not support the use of absolute lymphocyte count to determine antiretroviral therapy initiation in Fiji.

    adaptive exponentially weighted moving average (EWMA plan is developed for signalling unusually high incidence when monitoring a time series of nonhomogeneous daily disease counts. A Poisson transitional regression model is used to fit background/expected trend in counts and provides “one-day-ahead” forecasts of the next day's count. Departures of counts from their forecasts are monitored. The paper outlines an approach for improving early outbreak data signals by dynamically adjusting the exponential weights to be efficient at signalling local persistent high side changes. We emphasise outbreak signals in steady-state situations; that is, changes that occur after the EWMA statistic had run through several in-control counts.

    Many high resolution event counting devices process one event at a time and cannot register simultaneous events. In this article a frame-based readout event counting detector consisting of a pair of Microchannel Plates and a quad Timepix readout is described. More than 10{sup 4} simultaneous events can be detected with a spatial resolution of ~55 µm, while >10{sup 3} simultaneous events can be detected with <10 µm spatial resolution when event centroiding is implemented. The fast readout electronics is capable of processing >1200 frames/sec, while the global count rate of the detector can exceed 5×10{sup 8} particles/s when no timing information on every particle is required. For the first generation Timepix readout, the timing resolution is limited by the Timepix clock to 10–20 ns. Optimization of the MCP gain, rear field voltage and Timepix threshold levels are crucial for the device performance and that is the main subject of this article. These devices can be very attractive for applications where the photon/electron/ion/neutron counting with high spatial and temporal resolution is required, such as energy resolved neutron imaging, Time of Flight experiments in lidar applications, experiments on photoelectron spectroscopy and many others.

    2008-12-01

    Full Text Available The tenth century in Iraq and Syria saw an unprecedented rise in the number of canonical poets who were delivering glorious praise hymns (madīḥ to middling members of society. Scholars have posed many theories in the past 30 years to explain the function and purpose of praise hymns for royalty and rulers, but why would ordinary men who had no hope of rulership pay painful sums to commission praise hymns in their favor? This article examines the emergence of a new kind of sociability and patronage in the tenth century that enabled middling people to form alliances and exercise influence in shaping ideals of government, leadership and manhood. Examples are given of poems to patrons of middle rank who gain glory and influence via the artistic endorsement of al-Mutanabbī (d. 965: The first ode restores the public dignity of a nineteen-year-old soldier who lost his face in battle; in the second ode, the poet glorifies and defends a state clerk who had little-known Sufi leanings; in the third ode, the poet vindicates an unmasked pseudo- Muslim who was in private a Christian. Using J. Habermas’s theory of the “Public Sphere,” I show the way these odes illustrate how middling members of society gained influence in a public sphere of participation and took measures to preserve that influence.

    En el siglo X, y en la zona de Siria e Iraq, el número de poetas canónicos que dedicaron panegíricos (madīḥ a miembros no destacados de la sociedad experimentó un incremento sin precedentes. A lo largo de los últimos treinta años, especialistas en este campo han formulado diversas teorías sobre los himnos de alabanza dedicados a la realeza y a los gobernantes, pero ¿qué llevó a personas corrientes, sin ninguna aspiración de llegar a gobernar, a pagar grandes cantidades de dinero por himnos de alabanza en su honor?

    The counting losses introduced by the dead time of a counting system are a limiting factor in counting measurements. The purpose of this work is to report an efficient method for the measurement of the effective dead time of a counting system and to characterize its dead time behavior, providing a way to investigate each experimental situation. The method, which we designate as Delayed and Mixed Pulses method, is based on the artificial piling-up of detector pulses with electronic pulses delayed by a specific time interval. It is applicable to the measurement of the effective dead time of a counting system, including both pile-up effects and the dead time characteristics of the elements of the counting chain. With counting systems relying on gaseous radiation detectors, we achieved a standard uncertainty of about 5-10% in the dead times measured.

    We derive the general counting rules for a quantum effective field theory (EFT) in $\\mathsf{d}$ dimensions. The rules are valid for strongly and weakly coupled theories, and predict that all kinetic energy terms are canonically normalized. They determine the energy dependence of scattering cross sections in the range of validity of the EFT expansion. The size of cross sections is controlled by the $\\Lambda$ power counting of EFT, not by chiral counting, even for chiral perturbation theory ($\\chi$PT). The relation between $\\Lambda$ and $f$ is generalized to $\\mathsf{d}$ dimensions. We show that the naive dimensional analysis $4\\pi$ counting is related to $\\hbar$ counting. The EFT counting rules are applied to $\\chi$PT, to Standard Model EFT and to the non-trivial case of Higgs EFT, which combines the $\\Lambda$ and chiral counting rules within a single theory.

    Full Text Available Background/Aim: Acute appendicitis is one of the most common acute intraabdominal affections seen in surgical departments, which can be treated easily if an accurate diagnosis is made in time. Otherwise, delay in diagnosis and treatment can lead to diffuse peritonitis. Materials and Methods: A study was conducted on 110 patients who were operated for acute appendicitis to determine the role and predictive value of the total leucocyte count (TLC, C-reactive protein (CRP and percentage of neutrophil count in the diagnosis of acute appendicitis. Preoperative TLC, CRP and percentage of neutrophil count were determined and were compared with the results of the histopathology of the removed appendix. Results: Of all the patients studied, 92 had histopathologically positive appendicitis. The TLC was found to be significantly high in 90 patients who proved to have acute appendicitis, whereas CRP was high in only 88 patients and neutrophil percentage was raised in 91; four had a normal CRP level. Thus, TLC had a sensitivity, specificity and positive predictive value of 97.82%, 55.55% and 91.8%, respectively. CRP had a sensitivity, specificity and positive predictive value of 95.6%, 77.77% and 95.6% respectively. Percentage of neutrophil count had a sensitivity, specificity and positive predictive value of 98.9%, 38.88% and 89.21%, respectively. When used in combination, there was a marked improvement in the specificity and the positive predictive value to 88.04% and 98.7%, respectively. Conclusion: The inflammatory markers, i.e., TLC, CRP and neutrophil count can be helpful in the diagnosis when measured together as this increases their specificity and positive predictive value.

    Dietary deficiency causes abnormalities in circulating lymphocyte counts. For the present paper, we evaluated correlations between total and subpopulation lymphocyte counts (TLC, SLCs) and parameters of nutrition in peritoneal dialysis (PD) patients. Studies were carried out in 55 patients treated with PD for 22.2 +/- 11.4 months. Parameters of nutritional status included total body mass, lean body mass (LBM), body mass index (BMI), and laboratory indices [total protein, albumin, iron, ferritin, and total iron binding capacity (TIBC)]. The SLCs were evaluated using flow cytometry. Positive correlations were seen between TLC and dietary intake of niacin; TLC and CD8 and CD16+56 counts and energy delivered from protein; CD4 count and beta-carotene and monounsaturated fatty acids 17:1 intake; and CD19 count and potassium, copper, vitamin A, and beta-carotene intake. Anorexia negatively influenced CD19 count. Serum albumin showed correlations with CD4 and CD19 counts, and LBM with CD19 count. A higher CD19 count was connected with a higher red blood cell count, hemoglobin, and hematocrit. Correlations were observed between TIBC and TLC and CD3 and CD8 counts, and between serum Fe and TLC and CD3 and CD4 counts. Patients with a higher CD19 count showed a better clinical-laboratory score, especially less weakness. Patients with a higher CD4 count had less expressed insomnia. Quantities of ingested vitamins and minerals influence lymphocyte counts in the peripheral blood of PD patients. Evaluation of TLC and SLCs is helpful in monitoring the effectiveness of nutrition in these patients.

  14. 13/2 ways to count curves

    In the past 20 years, compactifications of the families of curves in algebraic varieties X have been studied via stable maps, Hilbert schemes, stable pairs, unramified maps, and stable quotients. Each path leads to a different enumeration of curves. A common thread is the use of a 2-term deformation/obstruction theory to define a virtual fundamental class. The richest geometry occurs when X is a nonsingular projective variety of dimension 3. We survey here the 13/2 principal ways to count curves with special attention to the 3-fold case. The different theories are linked by a web of conjectural relationships which we highlight. Our goal is to provide a guide for graduate students looking for an elementary route into the subject.

    This document is intended to serve as a comprehensive applications guide to passive neutron multiplicity counting, a new nondestructive assay (NDA) technique developed over the past ten years. The document describes the principles of multiplicity counter design, electronics, and mathematics. Existing counters in Department of Energy (DOE) facilities are surveyed, and their operating requirements and procedures and defined. Current applications to plutonium material types found in DOE facilities are described, and estimates of the expected assay precision and bias are given. Lastly, guidelines for multiplicity counter selection and procurement are summarized. The document also includes a detailed collection of references on passive neutron coincidence and multiplicity publications over the last ten to fifteen years.

    . RESULTS: The T-lymphocyte counts for both implant types declined over the 2-year period. This decline was statistically significant for CD3(+)CD8(+) in the THA group, with a regression coefficient of -0.04 × 10(9)cells/year (95% CI: -0.08 to -0.01). Regression analysis indicated a depressive effect...... of cobalt ions in particular on T-cells with 2-year whole-blood cobalt regression coefficients for CD3+ of -0.10 (95% CI: -0.16 to -0.04) × 10(9) cells/parts per billion (ppb), for CD3+CD4+ of -0.06 (-0.09 to -0.03) × 10(9) cells/ppb, and for CD3(+)CD8(+) of -0.02 (-0.03 to -0.00) × 10(9) cells/ppb...

    We describe a general procedure for using number counts of any object to constrain the probability distribution of the primordial fluctuations, allowing for generic weak non-Gaussianity. We apply this procedure to use limits on the abundance of primordial black holes and dark matter ultracompact minihalos (UCMHs) to characterize the allowed statistics of primordial fluctuations on very small scales. We present constraints on the power spectrum and the amplitude of the skewness for two different families of non-Gaussian distributions, distinguished by the relative importance of higher moments. Although primordial black holes probe the smallest scales, ultracompact minihalos provide significantly stronger constraints on the power spectrum and so are more likely to eventually provide small-scale constraints on non-Gaussianity.

    The properties of avalanche photodiodes and associated electronics required for photon counting in the Geiger and the sub-Geiger modes are reviewed. When the Geiger mode is used, there are significant improvements reported in overall photon detection efficiencies (approaching 70% at 633 nm), and a timing jitter (under 200 ps) is achieved with passive quenching at high overvoltages (20-30 V). The results obtained by using an active-mode fast quench circuit capable of switching overvoltages as high as 15 V (giving photon detection efficiencies in the 50% range) with a dead time of less than 50 ns are reported. Larger diodes (up to 1 mm in diameter) that are usable in the Geiger mode and that have quantum efficiencies over 80% in the 500-800-nm range are also reported.

    The skyline of a set of points in the plane is the subset of maximal points, where a point (x,y) is maximal if no other point (x',y') satisfies x'≥ x and y'≥ x. We consider the problem of preprocessing a set P of n points into a space efficient static data structure supporting orthogonal skyline...... counting queries, i.e. given a query rectangle R to report the size of the skyline of P\\cap R. We present a data structure for storing n points with integer coordinates having query time O(lg n/lglg n) and space usage O(n). The model of computation is a unit cost RAM with logarithmic word size. We prove...

    In this dissertation we study the problem of calculating equivariant volumes of moduli-spaces of framed instantons. The motivation for this is given by instanton counting, a recent development in theoretical physics that gives a direct approach to the non-perturbative study of certain super-symmetric quantum field theories. We develop a strategy for calculating the integrals using a combination of several techniques in symplectic geometry and equivariant cohomology. Most importantly we use an equivariant version of non-abelian localization, applied to the ADHM-construction of the moduli-spaces. Furthermore, we reduce the problem to a compact setting by means of varying compactifications using symplectic cuts, recovering the original integral over a non-compact space as the limit of integrals over compact spaces. In contrast with previous applications, in our case the contribution at infinity introduced by these compactifications turns out to be of primordial importance. We illustrate this method by explicitly...
