    Full Text Available En nuestro país no hay un registro estandarizado de los eventos cardíacos que requieren reanimación cerebro-cardio-pulmonar (RCCP siguiendo los lineamientos "Utstein". El propósito de este estudio fue determinar la calidad de los registros extrahospitalarios de paro cardíaco en el adulto, en Bogotá-Colombia. Entre enero y marzo de 2005 se realizó un análisis retrospectivo de los casos que correspondieron a paro cardíaco en el adulto atendidos por el "Centro Regulador de Urgencias del Distrito (CRU". El estudio reveló un registro deficiente de los eventos que requirieron RCCP realizados a nivel prehospitalario, e identificó al trauma como causa de paro cardíaco en 22% de los casos, una cifra particularmente elevada si se compara con los reportes mundiales, que oscilan entre 5% y 8%. Recomienda la estandarización del registro de paro cardíaco en el adulto, para lo cual se sugiere utilizar el formato de registro que sigue los lineamientos "Utstein".There is not a standardized registry form of cardiac events requiring cardiopulmonary resuscitation (CPR in our country such as the Utstein style. The purpose of this study was to determine the quality of the registries of out-ofhospital cardiac arrests in Bogotá-Colombia. A retrospective survey of registries of cardiac events assisted by a regulatory center "Centro Regulador de Urgencias del Distrito (CRU" was conducted, between January and March, 2005. The study reveals a poor registry of outof-hospital cardiac arrest in Bogotá-Colombia, and identifies trauma as the cause of cardiac arrest in 22% of cases, a particularly high figure compared with 5-8% registered worldwide. Recommend the standardization of the registry form of out-of-hospital cardiac arrest and suggest to use the "uniform reporting of data following cardiac arrest - the Utstein style". The registry forms are shown in appendix 1-2. Suggestions are welcome.

  7. The PANDA Grid

    International Nuclear Information System (INIS)

    In order to fulfill the computing demands of the future PANDA experiment at FAIR in Darmstadt a dedicated computing infrastructure will be required. A conceivable way of acquiring and managing the necessary computing power for simulations and data analysis is the Grid model. As an alternative to a centralized computing center this model allows to pool independent resources from multiple institutes or organizations. Although PANDA is not expected to acquire data before the year 2016 the PANDA collaboration is already experimenting with the PANDA Grid. The PANDA Grid uses the AliEn middleware which is entirely built around Open Source components and has been developed by the ALICE collaboration at CERN. The PANDA Grid currently consists of 10 sites. Due to the optimized installation procedures and portability of the AliEn software it is easy to add new resources, allowing the Grid to be expanded without disturbing its continuous operation. AliEn provides tools to pool hardware resources but also to manage the installation of common software packages. This feature is exploited to distribute, install, and update the PANDA analysis software (PandaRoot) on the different sites and with this to enable the PANDA Grid to perform PANDA related tasks. It is intended that PANDA Grid will provide in the order of 2-3000 CPUs by the end of 2008 and then constitute a powerful tool for upcoming PANDA detector design and physics case studies.

  9. PANDAS: a commentary.

    Science.gov (United States)

    Singer, Harvey S; Loiselle, Christopher

    2003-07-01

    PANDAS is an acronym for Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infection. As defined, the criteria include prepubertal children with either a tic or obsessive-compulsive disorder in whom a Group A beta-hemolytic streptococcal infection (GABHS) triggers the abrupt onset or exacerbation of tics/obsessive-compulsive behaviors. Pathophysiologically, it is proposed that antibodies produced against GABHS cross-react with neuronal cells, in a process involving molecular mimicry. Although PANDAS has received widespread notoriety, the existence of this condition has been questioned. This commentary reviews clinical and laboratory issues pertinent to the diagnosis of this entity. We conclude that PANDAS is an intriguing hypothesis that requires further confirmation.

    The PANDA project Even though air quality in many urbanized and industrialized areas of the world has improved as a result of mitigation actions, it has declined in other regions. This is specifically the case in many emerging countries where emissions have been increasing as a result of rapidly expanding motor vehicle fleets, growing industrial and power generation activities, and domestic and biomass burning. The situation is particularly acute in China and the Western Pacific Region with rapid industrialization and urbanization, where, in spite of efforts to reduce surface emissions of reactive gases, 360,000 people die prematurely from air pollution each year, according to the World Health Organization. The EU-funded PANDA project will offer scientific knowledge that will help China and other nations to use space and in-situ observations together with a modelling system to address improve air quality and human heath at the regional and global scales. Through the proposed cooperation between Europe and China, the following objectives will be reached before the completion of the Project: 1. Improvement of methods for monitoring air quality from combined space and in-situ observations 2. Elaboration of indicators for air quality, in support of European and Chinese policies 3. Development of toolboxes for air quality and emissions monitoring 4. Dissemination of information and educational activities, specifically in China. We would like to introduce the EU-funded project PANDA, and present the first results obtained through the project.

    Hypernuclear research will be one of the main topics addressed by the PANDA experiment at the planned Facility for Anti-proton and Ion Research FAIR at Darmstadt, Germany. A copious production of Xi-hyperons at a dedicated internal target in the stored anti-proton beam is expected, which will enable the high-precision gamma-spectroscopy of double strange systems for the first time. In addition to the general purpose PANDA setup, the hypernuclear experiments require an active secondary target of silicon layers and absorber material as well as high purity germanium (HPGe) crystals as gamma-detectors. The design of the setup and the development of these detectors is progressing: a first HPGe crystal with a new electromechanical cooling system was prepared and the properties of a silicon strip detector as a prototype to be used in the secondary target were studied. Simultaneously to the hardware projects, detailed Monte Carlo simulations were performed to predict the yield of particle stable hypernuclei. With the...

  2. Exotics at PANDA

    International Nuclear Information System (INIS)

    One highlight in the field of hadron spectroscopy is the recent discovery of unexpected charmonium-like X, Y, Z resonances. The nature of most of these states is still controversial and emphasizes the discussion on exotic states with gluonic degrees of freedom. The PANDA experiment, a core project of the future Facility for Antiproton and Ion Research (FAIR) at GSI in Darmstadt, will investigate antiproton annihilations with the aim to explore fundamental questions in the nonperturbative region of QCD. The PANDA detector, equipped with a fixed target and provided with a high quality antiproton beam in the momentum range between 1.5 and 15 GeV/c, is optimized for high precision measurements of hadrons with masses up to 5 GeV/c2 and in particular of resonances in the charmonium and open charm region. Due to the gluon-rich antiproton annihilation process, it is expected to observe exotic states and therefore to answer fundamental questions in this field. The physics program for the search for exotics is outlined and detailed feasibility studies are presented. Furthermore, strategies for the unambiguous determination of the quantum numbers of these states are discussed.

    diagnostic criteria for malnutrition is urgently required and suggests preferring IMS (Index Suggestive of Malnutrition because of its easy use, low coast and high sensitivity.Los cambios del estado nutricional son importantes en la práctica clínica porque se relacionan con un aumento de la morbilidad y de la mortalidad. Desde los años 1970 se han comunicado estudios sobre los problemas nutricionales de los adultos hospitalizados. La prevalencia de la malnutrición varía del 10 al 70% según los criterios diagnósticos empleados, el hospital en cuestión y la duración del ingreso. Objetivo: Evaluar en el primer día de estancia hospitalaria el estado nutricional de adultos ingresados para cirugía programada en un hospital público del estado de Acre, región amazónica, Brasil. Diseño del estudio: Estudio transversal desde el 7 de abril hasta el 22 de mayo de 2002. Pacientes y métodos: Se efectuaron 155 evaluaciones consecutivas del estado nutricional mediante varios parámetros, a saber, la evaluación subjetiva global (ESG, medidas antropométricas y algunos datos de laboratorio. Para el diagnóstico de la malnutrición se adoptó el índice de malnutrición (ISM propuesto por Waitzberg. Para evaluar la obesidad se empleó el IMC (índice de masa corporal con los valores discriminatorios recomendados por la OMS. Resultados: El 75,2% pertenecía al sexo femenino. El promedio de edad ascendía a 34,4 ± 10,1 años. El grupo racial predominante era el mulato (63,1%. La cirugía más común fue la ginecológica (43,6%.

    The PANDA experiment at the new Facility for Antiproton and Ion Research in Europe (FAIR) at GSI, Darmstadt, will study fundamental questions of hadron physics and QCD using high-intensity cooled antiproton beams with momenta between 1.5 and 15 GeV/c. Efficient Particle Identification for a wide momentum range and the full solid angle is required for reconstructing the various physics channels of the PANDA program. Hadronic Particle Identification in the barrel region of the detector will be provided by a DIRC counter. The design is based on the successful BABAR DIRC with important improvements, such as focusing optics and fast photon timing. Several of these improvements, including different radiator geometries and optics, were tested in particle beams at GSI and at CERN. The evolution of the conceptual design of the PANDA Barrel DIRC and the performance of complex prototypes in test beam campaigns will be discussed.

    The PANDA detector at the international accelerator Facility for Antiproton and Ion Research in Europe (FAIR) addresses fundamental questions of hadron physics. Experiments concerning charmonium spectroscopy, the search for hybrids and glueballs and the interaction of hidden and open charm particles with nucleons and nuclei will be performed with antiproton beams impinging on hydrogen or nuclear targets. Cooled beams allow the precision scan of resonances in formation experiments. The momentum range of the antiproton beam between 1.5 GeV/c and 15 GeV/c tests predictions by perturbation theory and will reveal deviations originating from strong QCD . An excellent hadronic particle identification will be accomplished by DIRC (Detection of Internally Reflected Cherenkov light) counters. The design for the barrel region is based on the successful BaBar DIRC with several key improvements, such as fast photon timing and a compact imaging region. DIRC designs based on different radiator geometries with several focusing options were studied in simulation. The performance of each design was characterized in terms of photon yield and single photon Cherenkov angle resolution. Selected design options were implemented in prototypes and tested with hadronic particle beams at GSI and CERN.

  19. Strong interaction studies with PANDA

    CERN Document Server

    Messchendorp, J G

    2010-01-01

    The theory of Quantum Chromo Dynamics (QCD) reproduces the strong interaction at distances much shorter than the size of the nucleon. At larger distance scales, the generation of hadron masses and confinement cannot yet be derived from first principles on basis of QCD. The PANDA experiment at FAIR will address the origin of these phenomena in controlled environments. Beams of antiprotons together with a multi-purpose and compact detection system will provide unique tools to perform studies of the strong interaction. This will be achieved via precision spectroscopy of charmonium and open-charm states, an extensive search for exotic objects such as glueballs and hybrids, in-medium and hypernuclei spectroscopy, and more. An overview is given of the physics program of the PANDA collaboration.

  20. Physics with Antiprotons at PANDA

    International Nuclear Information System (INIS)

    The PANDA experiment is part of the core project of the planned Facility for Antiproton and Ion Research (FAIR) at GSI in Darmstadt (Germany)[1]. One major component of the upgraded accelerator complex is the High Energy Storage Ring (HESR) which will provide a high quality antiproton beam in the momentum range between 1.5 and 15 GeV/c. PANDA, a fixed target experiment directly implemented in the HESR, will investigate antiproton annihilations with the aim to explore fundamental questions in the cross over region of the non perturbative and the strong QCD. Due to the planned extensive physics program a multipurpose detector with a nearly complete solid angle coverage, proper particle identification over a large momentum range, and high resolution calorimetry for neutral particles is required. After an overview about the goals and the detector design of the PANDA experiment major parts of the planned physics program will be discussed, namely the meson spectroscopy and the search for exotics in the charmonium and open charm region

    An autoimmune-mediated mechanism involving molecular mimicry has been proposed for a variety of pediatric movement disorders that occur after a streptococcal infection. In this study, anti-basal ganglia antibodies (ABGA) were measured in 15 children with the diagnosis of pediatric autoimmune neuropsychiatric disorder associated with streptococcal infection (PANDAS) and compared with those in 15 controls. ELISA and Western immunoblotting (WB) methods were used to detect ABGA against supernatant (S1), pellet (P2), and synaptosomal preparations from adult postmortem caudate, putamen, and globus pallidus. ELISA optical density values did not differ between PANDAS patients and controls across all preparations. Immunoblotting identified multiple bands in all subjects with no differences in the number of bands or their total density. Discriminant analysis, used to assess mean binding patterns, showed that PANDAS patients differed from controls only for the caudate S1 fraction (Wilks' lambda = 0.0236, P tic subjects providing the greatest discrimination. Among the epitopes contributing to differences between PANDAS and control in the caudate S1 fraction, mean binding to the epitope at 183 kDa was the most different between groups. In conclusion, ELISA measurements do not differentiate between PANDAS and controls, suggesting a lack of major antibody changes in this disorder. Further immunoblot analyses using a caudate supernatant fraction are required to completely exclude the possibility of minor antibody repertoire differences in PANDAS subjects, especially in those who primarily have tics.

  11. Timebased detector simulation for the PANDA Experiment

    International Nuclear Information System (INIS)

    PANDA is one of the main experiments of the future Facility for Antiproton and Ion Research (FAIR) at Darmstadt. Its purpose is the examination of the strong force in the energy regime of charmonium spectroscopy. For this goal PANDA uses a phasespace cooled antiproton beam with a momentum range of 1.5-15 GeV/c which interacts with either a hydrogen target or with more complex nuclei. To be able to handle different physics questions PANDA abstains from the use of a first level hardware trigger. The complete detector data is read out to the control room where a software based event selection is done with the full PANDA data set.This readout concept sets huge requirements on the readout system of PANDA as well as the used trigger algorithms. To be able to develop and test those it is necessary to do a chronologically ordered data simulation which differs strongly from the usual event based Monte-Carlo simulation of detectors. The existing simulation software pandaRoot was extended to give both possibilities: event and time based simulation. The concept and first simulation results are shown in the presentation.

    The giant panda׳s teeth possess remarkable load-bearing capacity and damage resistance for masticating bamboos. In this study, the hierarchical structure and mechanical behavior of the giant panda׳s tooth enamel were investigated under indentation. The effects of loading orientation and location on mechanical properties of the enamel were clarified and the evolution of damage in the enamel under increasing load evaluated. The nature of the damage, both at and beneath the indentation surfaces, and the underlying toughening mechanisms were explored. Indentation cracks invariably were seen to propagate along the internal interfaces, specifically the sheaths between enamel rods, and multiple extrinsic toughening mechanisms, e.g., crack deflection/twisting and uncracked-ligament bridging, were active to shield the tips of cracks from the applied stress. The giant panda׳s tooth enamel is analogous to human enamel in its mechanical properties, yet it has superior hardness and Young׳s modulus but inferior toughness as compared to the bamboo that pandas primarily feed on, highlighting the critical roles of the integration of underlying tissues in the entire tooth and the highly hydrated state of bamboo foods. Our objective is that this study can aid the understanding of the structure-mechanical property relations in the tooth enamel of mammals and further provide some insight on the food habits of the giant pandas.

    The design of the Barrel DIRC detector for the future PANDA experiment at FAIR contains several important improvements compared to the successful BABAR DIRC, such as focusing and fast timing. To test those improvements as well as other design options a prototype was build and successfully tested in 2012 with particle beams at CERN. The prototype comprises a radiator bar, focusing lens, mirror, and a prism shaped expansion volume made of synthetic fused silica. An array of micro-channel plate photomultiplier tubes measures the location and arrival time of the Cherenkov photons with sub-nanosecond resolution. The development of a fast reconstruction algorithm allowed to tune construction details of the detector setup with test beam data and Monte-Carlo simulations.

    Inbreeding and relatedness in wild panda populations are important parameters for panda conservation. Habitat loss and fragmentation are expected to increase inbreeding but the actual inbreeding levels in natural panda habitats were unknown. Using 150,025 SNPs and 14,926 SNPs selected from published whole-genome sequences, we estimated genomic inbreeding coefficients and relatedness of 49 pandas including 34 wild pandas sampled from six habitats. Qinling and Liangshan pandas had the highest levels of inbreeding and relatedness measured by genomic inbreeding and coancestry coefficients, whereas the inbreeding levels in Qionglai and Minshan were 28-45% of those in Qinling and Liangshan. Genomic coancestry coefficients between pandas from different habitats showed that panda populations from the four largest habitats, Minshan, Qionglai, Qinling and Liangshan, were genetically unrelated. Pandas between these four habitats on average shared 66.0-69.1% common alleles and 45.6-48.6% common genotypes, whereas pandas within each habitat shared 71.8-77.0% common alleles and 51.7-60.4% common genotypes. Pandas in the smaller populations of Qinling and Liangshan were more similarly to each other than pandas in the larger populations of Qionglai and Minshan according to three genomic similarity measures. Panda genetic differentiation between these habitats was positively related to their geographical distances. Most pandas separated by 200 kilometers or more shared no common ancestral alleles. The results provided a genomic quantification of the actual levels of inbreeding and relatedness among pandas in their natural habitats, provided genomic confirmation of the relationship between genetic diversity and geographical distances, and provided genomic evidence to the urgency of habitat protection.

    We investigate the relative development of the carnivoran radial sesamoids to untangle the evolution of this iconic structure. In the pandas (both giant and red), this `false thumb' is known to perform a grasping role during bamboo feeding in both the red and giant pandas. An original locomotor role has been inferred for ailurids, but this remains to be ascertained for ursids. A large sample of radial sesamoids of Indarctos arctoides from the Miocene of Batallones-3 (Spain) indicates that this early ailuropodine bear displayed a relatively hypertrophied radial sesamoid, with a configuration more similar to that of the red panda and other carnivorans than to that of giant pandas. This false thumb is the first evidence of this feature in the Ursidae, which can be linked to a more herbivorous diet. Moreover, in the two extant pandas, the false thumb should not be interpreted as an anatomical convergence, but as an exaptive convergence regarding its use during the bamboo feeding, which changes the evolutionary view of this singular structure.

Data analysis identified the theme: defining the modality of family support during hospitalization. This theme aggregates two main categories: becoming the family visitor and becoming the family companion. Through the analysis, it could be observed how established rules, which aims at disciplining and developing an efficient work in the hospital, can expose the lack of autonomy in the work process to modify relations in this context and how the familiar appropriation, as part of the health team, is far from being considered in the institutions.Se trata de un estudio cualitativo que utiliza como referencial metodológico la Grounded Theory y como referencial teórico el Proceso de Trabajo en Enfermería para comprender el rol asumido por el enfermero frente a las normas y rutinas hospitalarias, de los familiares visitantes y de los acompañantes de adultos y ancianos internados en un hospital universitario. El análisis de los datos permitió la identificación del tema: definiéndose la modalidad de apoyo familiar durante la hospitalización, que reúne dos categorías principales: tornándose un familiar visitante y tornándose un familiar acompañante. Por medio del análisis, se puede profundizar la comprensión acerca de las reglas establecidas que, con el objetivo de disciplinar y hacer eficiente el trabajo desarrollado en el hospital, permite explicar la ausencia de autonomía en el proceso de trabajo, para de esta forma, modificar las relaciones en este contexto y resaltar la integración a la institución del familiar como parte del equipo de salud.Trata-se de estudo qualitativo, utilizando-se como referencial

    Full Text Available Giant pandas (Ailuropoda melanoleuca are one of the most widely recognized endangered species globally. Habitat loss and fragmentation are the main threats, and climate change could significantly impact giant panda survival. We integrated giant panda habitat information with general climate models (GCMs to predict future geographic distribution and fragmentation of giant panda habitat. Results support a major general prediction of climate change—a shift of habitats towards higher elevation and higher latitudes. Our models predict climate change could reduce giant panda habitat by nearly 60% over 70 years. New areas may become suitable outside the current geographic range but much of these areas is far from the current giant panda range and only 15% fall within the current protected area system. Long-term survival of giant pandas will require the creation of new protected areas that are likely to support suitable habitat even if the climate changes.

  6. Spatiotemporal dynamics of giant panda habitat: Implications for panda conservation under a changing environment

    Tuan Mu, Mao-Ning

    Under the current rapidly changing environment, effective and efficient actions for biodiversity conservation rely on detailed knowledge on the spatiotemporal dynamics of species distribution and habitat. However, inadequate spatiotemporal information on species habitat has compromised conservation effectiveness, even for one of the most endangered species on Earth, the giant panda (Ailuropoda melanoleuca). To address this information gap, the objectives of this dissertation were to: (1) develop an approach for remotely detecting the distribution of understory bamboo, the panda's staple food, across large geographic regions; (2) develop a modeling approach for monitoring panda habitat changes across space and time; (3) evaluate the effects of current conservation efforts on short-term panda habitat changes; and (4) assess the potential impacts of climate change on long-term panda habitat dynamics. Using two dominant bamboo species in Wolong Nature Reserve, China, I showed that an integration of species distribution modeling with land surface phenology obtained from high temporal resolution remotely sensed data is a promising approach for providing detailed information on understory bamboo distribution across large geographic regions. Derived from time series data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS), eleven land surface phenology metrics successfully captured the phenological characteristics of vegetation caused by understory bamboo. In addition, a species distribution model (SDM) built using the maximum entropy modeling approach (Maxent) accurately captured the distribution of understory bamboo species across the reserve based on their phenological characteristics. I further demonstrated the usefulness of the phenology-based model for not only characterizing panda habitat across space, but also monitoring its dynamics over time.

    The recognition of the five criteria for PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections) by Swedo et al established a homogenous subgroup of children with childhood onset obsessive-compulsive disorder (OCD) and/or tic disorders. The five clinical characteristics that define the PANDAS subgroup are the presence of OCD and/or tic disorder, prepubertal age of onset, abrupt onset and relapsing-remitting symptom course, association with neurological abnormalities during exacerbations (adventitious movements or motoric hyperactivity), and a temporal association between symptom exacerbations and a Group-A beta-hemolytic streptococcal (GAS) infection. These five criteria have been used for the purpose of systematic research on the phenomenology and unique therapies for the PANDAS subgroup as well as studies of the pathophysiology of post-streptococcal OCD and tic disorders. The etiology of OCD and tics in the PANDAS subgroup is unknown, but is theorized to occur as a result of post-streptococcal autoimmunity in a manner similar to that of Sydenham's chorea. The working hypothesis for the pathophysiology begins with a GAS infection in a susceptible host that incites the production of antibodies to GAS that crossreact with the cellular components of the basal ganglia, particularly in the caudate nucleus and putamen. The obsessions, compulsions, tics, and other neuropsychiatric symptoms seen in these children are postulated to arise from an interaction of these antibodies with neurons of the basal ganglia.

    Streptococcal infection in children is usually benign and self-limited. In a small percentage of children, prominent neurologic and/or psychiatric sequelae can occur. Sydenham chorea is the best defined and best recognized. PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection) is a well-defined syndrome in which tics (motor and/or vocal) and/or obsessive-compulsive disorder consistently exacerbate in temporal correlation to a group A beta-hemolytic streptococcal infection. PANDAS constitutes a subset of children with tics, Tourette syndrome, and obsessive-compulsive disorder. In addition to strictly defined PANDAS, we and others have recognized several PANDAS variants, including adult-onset variant, a dystonic variant, a myoclonic variant, and a "chronic" PANDAS variant. The nosology and classification of these entities are rapidly evolving. The recognition that some pediatric neurobehavioral syndromes have infectious and/or immunologic triggers points to important new avenues of disease treatment. In this review, we summarize this complex and rapidly evolving area of clinical research. PMID:16970875

    The aim of this research is to develop a planar DIRC detector showing advantages and performance similar to a classical, barrel shaped DIRC, but at smaller polar angles which cannot be accessed using a cylindrical geometry. The device will complement the PANDA Barrel DIRC by covering polar angles from 5° to 22°. The envisaged π/K-separation is ≥ 3 σ up to 4 GeV/c. A major challenge is the adaption of the device to the PANDA environment including a magnetic field of ~1-2 T, high rates and radiation, limited space for optics and sensors as well as the lack of a common first-level trigger. This paper discusses a detector design which forms a compromise between these constraints and available hardware, a specific analytic reconstruction method, a performance estimation based on Geant4 simulations and finally the successful particle identification using a recent R&D prototype.

  1. Online software trigger at PANDA/FAIR

    International Nuclear Information System (INIS)

    The PANDA experiment at the FAIR facility will employ a novel trigger-less readout concept. PANDA will have no first level hardware trigger and apply a high level software trigger to do fast event selection based on the physics properties of reconstructed events. A trigger-less data stream implies that an event selection requires track reconstruction and pattern recognition to be performed online, analysing data under real time condition at the event rates up to 40 MHz. A significant event rate reduction is required to reject effectively background events, while retaining the interesting events at the same time. The projected reduction factor is 10-3. Real time event selection in this environment is very challenging and rely on sophisticated algorithms in the software trigger. This presentation shows the implementation and performance tests of the online high level physics trigger algorithms. The impact of parameters such as momentum, mass resolution, and PID probability for the event filtering are presented.

    The PANDA experiment at the FAIR facility will be a multipurpose hermetic spectrometer covering the full solid angle range. A key role for several physics cases will be played by the electromagnetic calorimeter. This includes ca. 15000 PbWO{sub 4} scintillating crystals arranged in a central barrel, a forward and a backward end-cap. The backward end-cap of the PANDA electromagnetic calorimeter is composed by 540 straight crystals covering the scattering angles between 147 {sup circle} and 161 {sup circle}. They are housed in the so-called alveoli which are carbon fibre boxes, providing both strength and low material budget. The crystals are to work at -25 C in order to improve the light yield. To achieve this temperature a cooling system and thermal insulation are needed. The cooling system removes the heat coming from the electronics and through walls, cables and mechanical supports. Vacuum insulated panels are installed as a thermal shielding. Avalanche Photodiodes (APD) have been chosen as photon detectors, since they are still functional under strong magnetic fields. ASIC chips will be used to amplify the APD signal, this preamplifier features low noise and low heat generation. Due to the weight of this detector, it will be supported from the outside of the PANDA target spectrometer in a counter lever arm position.

    We report an outbreak of canine distemper virus (CDV) infection among endangered giant pandas (Ailuropoda melanoleuca). Five of six CDV infected giant pandas died. The surviving giant panda was previously vaccinated against CDV. Genomic sequencing of CDV isolated from one of the infected pandas (giant panda/SX/2014) suggests it belongs to the Asia-1 cluster. The hemagglutinin protein of the isolated virus and virus sequenced from lung samples originating from deceased giant pandas all possessed the substitutions V26M, T213A, K281R, S300N, P340Q, and Y549H. The presence of the Y549H substitution is notable as it is found at the signaling lymphocytic activation molecule (SLAM) receptor-binding site and has been implicated in the emergence of highly pathogenic CDV and host switching. These findings demonstrate that giant pandas are susceptible to CDV and suggest that surveillance and vaccination among all captive giant pandas are warranted to support conservation efforts for this endangered species.

    The giant panda is an icon of conservation and survived a large-scale bamboo die off in the 1980s in China. Captive breeding programs have produced a large population in zoos and efforts continue to reintroduce those animals into the wild. However, we lack sufficient knowledge of their physiological ecology to determine requirements for survival now and in the face of climate change. We measured resting and active metabolic rates of giant pandas in order to determine if current bamboo resources were sufficient for adding additional animals to populations in natural reserves. Resting metabolic rates were somewhat below average for a panda sized mammal and active metabolic rates were in the normal range. Pandas do not have exceptionally low metabolic rates. Nevertheless, there is enough bamboo in natural reserves to support both natural populations and large numbers of reintroduced pandas. Bamboo will not be the limiting factor in successful reintroduction. PMID:27264109

    Population viability analysis (PVA) is a tool to evaluate the risk of extinction for endangered species and aid conservation decision-making.The quality of PVA output is dependent on parameters related to population dynamics and life-history; however,it has been difficult to collect this information for the giant panda (Aliuropoda melanoleuca),a rare and endangered mammal native to China,confined to some 30 fragmented habitat patches.Since giant pandas are long-lived,mature late,have lower reproductive rates,and show little sexual dimorphism,obtaining data to perform adequate PVA has been difficult.Here,we develop a parameter sensitivity index by modeling the dynamics of six giant panda populations in the Minshan Mountains,in order to determine the parameters most influential to giant panda populations.Our data shows that the giant panda populations are most sensitive to changes in four female parameters:initial breeding age,reproductive rate,mortality rate between age 0 and 1,and mortality rate of adults.The parameter sensitivity index strongly correlated with initial population size,as smaller populations were more sensitive to changes in these four variables.This model suggests that demographic parameters of females have more influence on the results of PVA,indicating that females may play a more important role in giant panda population dynamics than males.Consequently,reintroduction of female individuals to a small giant panda population should be a high priority for conservation efforts.Our findings form a technical basis for the coming program of giant panda reintroduction,and inform which parameters are crucial to successfully and feasibly monitoring wild giant panda populations.

    PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections) is a rare clinical syndrome characterized by the presence of tics, Tourette syndrome, obsessive-compulsive disorder, or chorea in the context of an immediately precedent streptococcal infection. In this report, we describe the case of an 11-year-old boy who developed PANDAS with severe choreic movements. The criteria for PANDAS diagnosis were met. Moreover, serum antibrain antibodies were present. The patient was initially treated with tetrabenazine 12.5 mg twice daily with remission of the neurological symptoms. Subsequently, the patient underwent tonsillectomy and has been asymptomatic since, with antistreptolysin O titer levels in range. PMID:20207613

  13. Online software trigger at PANDA/FAIR

    International Nuclear Information System (INIS)

    The PANDA experiment at FAIR will employ a novel trigger-less read-out system. Since a conventional hardware trigger concept is not suitable for PANDA, a high level online event filter will be applied to perform fast event selection based on physics properties of the reconstructed events. A trigger-less data stream implies an event selection with track reconstruction and pattern recognition to be performed online, and thus analysing data under real time conditions at event rates of up to 40 MHz.The projected data rate reduction of about three orders of magnitude requires an effective background rejection, while retaining interesting signal events. Real time event selection in the environment of hadronic reactions is rather challenging and relies on sophisticated algorithms for the software trigger. The implementation and the performance of physics trigger algorithms presently studied with realistic Monte Carlo simulations is discussed. The impact of parameters such as momentum or mass resolution, PID probability, vertex reconstruction and a multivariate analysis using the TMVA package for event filtering is presented.

    At the future PANDA experiment at the FAIR facility in Darmstadt, proton-antiproton collisions will be studied at an energy up to {approx_equal}5.5 GeV, which suffices to produce charmed hadron pairs like D anti D or {Lambda}{sub c} anti {Lambda}{sub c}. Their yet unknown production cross sections are of special interest for flavour physics, since they could provide higher statistics for the investigation of charmed hadrons, if large enough. Importantly they also give the opportunity to study fundamental interaction dynamics of hadrons and its connection to QCD. It is a difficult task to predict these cross sections, since the energy here is still slightly above the production threshold and so not easily accessible to perturbative QCD. We describe the process by a model based on the effective exchange of intermediating hadrons according to Regge theory. An important ingredient are process-dependent coupling constants between certain hadrons, which we calculate using the method of QCD light-cone sum rules. Making use of the Regge model we give an improved estimate of the cross sections for exclusive open charm production at PANDA energies.

Os tiques e os sintomas obsessivo-compulsivos são as principais manifestações clínicas da doença e surgem após infecções estreptocócicas, provavelmente por mecanismos auto-imunes. Apesar de estes sintomas neuropsiquiátricos serem comuns na coréia reumática, também de etiologia pós-estreptocócica, em PANDAS faltam os movimentos clássicos da coréia e as outras manifestações de febre reumática. As possibilidades de terapia antimicrobiana e imunológica estão sendo pesquisadas e demonstram viabilidade de uso em alguns casos. CONCLUSÕES: Pesquisas ainda são necessárias para responder à pergunta-título.

    Full Text Available Abstract The term Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus infections (PANDAS was coined by Swedo et al. in 1998 to describe a subset of childhood obsessive-compulsive disorders (OCD and tic disorders triggered by group-A beta-hemolytic Streptococcus pyogenes infection. Like adult OCD, PANDAS is associated with basal ganglia dysfunction. Other putative pathogenetic mechanisms of PANDAS include molecular mimicry and autoimmune-mediated altered neuronal signaling, involving calcium-calmodulin dependent protein (CaM kinase II activity. Nonetheless the contrasting results from numerous studies provide no consensus on whether PANDAS should be considered as a specific nosological entity or simply a useful research framework. Herein we discuss available data that could provide insight into pathophysiology of adult OCD, or might explain cases of treatment-resistance. We also review the latest research findings on diagnostic and treatment.

    Full Text Available OBJECTIVE: to examine the transition of care in families caring for elderly persons who suffered the first episode of a cerebrovascular accident. METHODOLOGY: an instrumental ethnographic case study was used. The sample comprised 20 subjects: 10 caregivers and 10 elderly persons aged 65 or over, of both sexes, with diagnoses of first episode of cerebrovascular accident, capable of communicating, and requiring care from a main carer in their family. The data was collected through interviews, observation, existing documentation and field notes. Qualitative analysis techniques were used to codify and classify the data and to formulate significant categories, which generated typologies of care. RESULTS AND DISCUSSION: The central idea was the Transition of Care and showed the context in three typologies: The care process for the dependent elderly person, Strategies for the care process and Impact and acceptance of the limitations. CONCLUSION: The data indicates that caring for an elderly person after a cerebrovascular accident is a challenge for the family. The data permitted it possible to elaborate a proposal for a model for the organization of the work, with a view to holistic care delivery in the health services, forming a care network, which constitutes an advance for the area of nursing.OBJETIVO: examinar la transición del cuidado en familias que cuidan de adultos mayores que sufrieron el primer episodio de accidente cerebral vascular.

    Giant panda (Ailuropoda melanoleuca) conservation is a possible success story in the making. If extinction of this iconic endangered species can be avoided, the species will become a showcase program for the Chinese government and its collaborators. We reviewed the major advancements in ecological science for the giant panda, examining how these advancements have contributed to panda conservation. Pandas' morphological and behavioral adaptations to a diet of bamboo, which bear strong influence on movement ecology, have been well studied, providing knowledge to guide management actions ranging from reserve design to climate change mitigation. Foraging ecology has also provided essential information used in the creation of landscape models of panda habitat. Because habitat loss and fragmentation are major drivers of the panda population decline, efforts have been made to help identify core habitat areas, establish where habitat corridors are needed, and prioritize areas for protection and restoration. Thus, habitat models have provided guidance for the Chinese governments' creation of 67 protected areas. Behavioral research has revealed a complex and efficient communication system and documented the need for protection of habitat that serves as a communication platform for bringing the sexes together for mating. Further research shows that den sites in old-growth forests may be a limiting resource, indicating potential value in providing alternative den sites for rearing offspring. Advancements in molecular ecology have been revolutionary and have been applied to population census, determining population structure and genetic diversity, evaluating connectivity following habitat fragmentation, and understanding dispersal patterns. These advancements form a foundation for increasing the application of adaptive management approaches to move panda conservation forward more rapidly. Although the Chinese government has made great progress in setting aside protected areas

    Evidence from past studies indicates that adults and children with Obsessive-Compulsive Disorder (OCD) and Tourette syndrome (TS) experience subtle neuropsychological deficits. Less is known about neuropsychological functioning of children and adolescents with a symptom course consistent with the PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infection) subgroup of OCD and tics. To provide such information, we administered three tests of attention control and two of executive function to 67 children and adolescents (ages 5-16) diagnosed with OCD and/or tics and a symptom course consistent with the PANDAS subgroup and 98 healthy volunteers (HV) matched by age, sex, and IQ. In a paired comparison of the two groups, the PANDAS subjects were less accurate than HV in a test of response suppression. Further, in a two-step linear regression analysis of the PANDAS group in which clinical variables were added stepwise into the model and in the second step matching variables (age, sex, and IQ) were added, IQ emerged as a predictor of performance on this task. In the same analysis, ADHD diagnosis and age emerged as predictors of response time in a continuous performance task. Subdividing the PANDAS group by primary psychiatric diagnosis revealed that subjects with TS or OCD with tics exhibited a longer response time compared to controls than subjects with OCD only, replicating previous findings within TS and OCD. This study demonstrates that children with PANDAS exhibit neuropsychological profiles similar to those of their primary psychiatric diagnosis. PMID:18622810

    The ATLAS Production and Distributed Analysis System (PanDA) is a key component of the ATLAS distributed computing infrastructure. All ATLAS production jobs, and a substantial amount of user and group analysis jobs, pass through the PanDA system, which manages their execution on the grid. PanDA also plays a key role in production task definition and the data set replication request system. PanDA has recently been migrated from Brookhaven National Laboratory (BNL) to the European Organization for Nuclear Research (CERN), a process we describe here. We discuss how the new infrastructure for PanDA, which relies heavily on services provided by CERN IT, was introduced in order to make the service as reliable as possible and to allow it to be scaled to ATLAS's increasing need for distributed computing. The migration involved changing the backend database for PanDA from MySQL to Oracle, which impacted upon the database schemas. The process by which the client code was optimised for the new database backend is discussed. We describe the procedure by which the new database infrastructure was tested and commissioned for production use. Operations during the migration had to be planned carefully to minimise disruption to ongoing ATLAS offline computing. All parts of the migration were fully tested before commissioning the new infrastructure and the gradual migration of computing resources to the new system allowed any problems of scaling to be addressed.

    2013-02-01

    Full Text Available Diffusion magnetic resonance imaging (dMRI is widely used in both scientific research and clinical practice in in-vivo studies of the human brain. While a number of post-processing packages have been developed, fully automated processing of dMRI datasets remains challenging. Here, we developed a MATLAB toolbox named “Pipeline for Analyzing braiN Diffusion imAges” (PANDA for fully automated processing of brain diffusion images. The processing modules of a few established packages, including FMRIB Software Library (FSL, Pipeline System for Octave and Matlab (PSOM, Diffusion Toolkit and MRIcron, were employed in PANDA. Using any number of raw dMRI datasets from different subjects, in either DICOM or NIfTI format, PANDA can automatically perform a series of steps to process DICOM/NIfTI to diffusion metrics (e.g., FA and MD that are ready for statistical analysis at the voxel-level, the atlas-level and the Tract-Based Spatial Statistics (TBSS-level and can finish the construction of anatomical brain networks for all subjects. In particular, PANDA can process different subjects in parallel, using multiple cores either in a single computer or in a distributed computing environment, thus greatly reducing the time cost when dealing with a large number of datasets. In addition, PANDA has a friendly graphical user interface (GUI, allowing the user to be interactive and to adjust the input/output settings, as well as the processing parameters. As an open-source package, PANDA is freely available at http://www.nitrc.org/projects/panda/. This novel toolbox is expected to substantially simplify the image processing of dMRI datasets and facilitate human structural connectome studies.

    Full Text Available Hanna Rhee1, Daniel J Cameron21Medicine, San Diego, CA, 2Northern Westchester Hospital, Mount Kisco, NY, USAAbstract: Lyme disease (LD is a complex, multisystemic illness. As the most common vector-borne disease in the United States, LD is caused by bacterial spirochete Borrelia burgdorferi sensu stricto, with potential coinfections from agents of anaplasmosis, babesiosis, and ehrlichiosis. Persistent symptoms and clinical signs reflect multiorgan involvement with episodes of active disease and periods of remission, not sparing the coveted central nervous system. The capability of microorganisms to cause and exacerbate various neuropsychiatric pathology is also seen in pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS, a recently described disorder attributed to bacterium Streptococcus pyogenes of group A beta-hemolytic streptococcus in which neurologic tics and obsessive-compulsive disorders are sequelae of the infection. In the current overview, LD and PANDAS are juxtaposed through a review of their respective infectious etiologies, clinical presentations, mechanisms of disease development, courses of illness, and treatment options. Future directions related to immunoneuropsychiatry are also discussed.Keywords: neuroborreliosis, infection, obsessive-compulsive disorder, tic disorder, Borrelia burgdorferi, strep throat

  12. Implementation of a forward tracking system for anti PANDA

    International Nuclear Information System (INIS)

    The anti PANDA experiment at the future FAIR facility at GSI Darmstadt is planned to start operation in 2017 utilizing antiproton beams with beam momentum resolutions of Δp/p≤2 x 10-5. In particular, anti PANDA is well fit to perform resonance scans of exclusively produced charmonium(-like) states and thus provide absolute measurements of resonance widths. In this poster we report on the current status of the implementation of a forward tracking system for the anti PANDA detector. The forward tracking is of particular importance as anti PANDA is a fixed target experiment, and thus in charmonium production a large fraction of final state particles will be boosted toward forward angles. The key challenges for the implementation of a forward track finder and track fitter arise from a complicated magnetic field map as anti PANDA is comprised of a barrel part with a solenoid field of Bz=2 T and a forward detector part with a dipole field of B x L=2 Tm. The interference of the magnetic fields has to be taken into account. Furthermore, the forward tracking requires a matching of hits from numerous subdetectors (e.g. axial and stereo straw tubes, straw tube planes perpendicular to the beam axis, GEM tracker, etc.) with high accuracy.

  13. The PandaRoot framework for simulation, reconstruction and analysis

    International Nuclear Information System (INIS)

    The PANDA experiment at the future facility FAIR will study anti-proton proton and anti-proton nucleus collisions in a beam momentum range from 2 GeV/c up to 15 GeV/c. The PandaRoot framework is part of the FairRoot project, a common software framework for the future FAIR experiments, and is currently used to simulate detector performances and to evaluate different detector concepts. It is based on the packages ROOT and Virtual MonteCarlo with Geant3 and Geant4. Different reconstruction algorithms for tracking and particle identification are under development and optimization, in order to achieve the performance requirements of the experiment. In the central tracker a first track fit is performed using a conformal map transformation based on a helix assumption, then the track is used as input for a Kalman Filter (package genfit), using GEANE as track follower. The track is then correlated to the pid detectors (e.g. Cerenkov detectors, EM Calorimeter or Muon Chambers) to evaluate a global particle identification probability, using a Bayesian approach or multivariate methods. Further implemented packages in PandaRoot are: the analysis tools framework Rho, the kinematic fitter package for vertex and mass constraint fits, and a fast simulation code based upon parametrized detector responses. PandaRoot was also tested on an Alien-based GRID infrastructure. The contribution will report about the status of PandaRoot and show some example results for analysis of physics benchmark channels.

    2011-12-01

    The PanDA (Production and Distributed Analysis) Workload Management System is used for ATLAS distributed production and analysis worldwide. The needs of ATLAS global computing imposed challenging requirements on the design of PanDA in areas such as scalability, robustness, automation, diagnostics, and usability for both production shifters and analysis users. Through a system-wide job database, the PanDA monitor provides a comprehensive and coherent view of the system and job execution, from high level summaries to detailed drill-down job diagnostics. It is (like the rest of PanDA) an Apache-based Python application backed by Oracle. The presentation layer is HTML code generated on the fly in the Python application which is also responsible for managing database queries. However, this approach is lacking in user interface flexibility, simplicity of communication with external systems, and ease of maintenance. A decision was therefore made to migrate the PanDA monitor server to Django Web Application Framework and apply JSON/AJAX technology in the browser front end. This allows us to greatly reduce the amount of application code, separate data preparation from presentation, leverage open source for tools such as authentication and authorization mechanisms, and provide a richer and more dynamic user experience. We describe our approach, design and initial experience with the migration process.

    Full Text Available The red panda is the only living species of the genus Ailurus. Like giant pandas, red pandas are also highly specialized to feed mainly on highly fibrous bamboo. Although several studies have focused on the gut microbiota in the giant panda, little is known about the gut microbiota of the red panda. In this study, we characterized the fecal microbiota from both wild (n = 16 and captive (n = 6 red pandas using a pyrosequecing based approach targeting the V1-V3 hypervariable regions of the 16S rRNA gene. Distinct bacterial communities were observed between the two groups based on both membership and structure. Wild red pandas maintained significantly higher community diversity, richness and evenness than captive red pandas, the communities of which were skewed and dominated by taxa associated with Firmicutes. Phylogenetic analysis of the top 50 OTUs revealed that 10 of them were related to known cellulose degraders. To the best of our knowledge, this is the first study of the gut microbiota of the red panda. Our data suggest that, similar to the giant panda, the gut microbiota in the red panda might also play important roles in the digestion of bamboo.

    Experiments at the Large Hadron Collider (LHC) face unprecedented computing challenges. Heterogeneous resources are distributed worldwide at hundreds of sites, thousands of physicists analyse the data remotely, the volume of processed data is beyond the exabyte scale, while data processing requires more than a few billion hours of computing usage per year. The PanDA (Production and Distributed Analysis) system was developed to meet the scale and complexity of LHC distributed computing for the ATLAS experiment. In the process, the old batch job paradigm of locally managed computing in HEP was discarded in favour of a far more automated, flexible and scalable model. The success of PanDA in ATLAS is leading to widespread adoption and testing by other experiments. PanDA is the first exascale workload management system in HEP, already operating at more than a million computing jobs per day, and processing over an exabyte of data in 2013. There are many new challenges that PanDA will face in the near future, in addition to new challenges of scale, heterogeneity and increasing user base. PanDA will need to handle rapidly changing computing infrastructure, will require factorization of code for easier deployment, will need to incorporate additional information sources including network metrics in decision making, be able to control network circuits, handle dynamically sized workload processing, provide improved visualization, and face many other challenges. In this talk we will focus on the new features, planned or recently implemented, that are relevant to the next decade of distributed computing workload management using PanDA.

    Obsessive-compulsive disorder is a disabling disorder. Genetic predisposing factors may have an important role in the onset of the symptoms, but is not been individualized any specific gene yet. In the last years it has been demonstrated that obsessive-compulsive disease and/or tic syndromes may be triggered by an antecedent infection especially with group A beta-hemolytic streptococci. On the basis of recent studies has been postulated that in genetically predisposed individuals, certain streptococcal antigens trigger antibodies which, through a process of molecular mimicry, cross-react with epitopes on the basal ganglia. According to such hypothesis, the acronym PANDAS has been used to describe a subset of children with abrupt onset or exacerbations of OCD or tics, or both, following streptococcal infections. Neuroimaging studies reveal increased basal ganglia volumes, and the proposed cause involves the cross-reaction of streptococcal antibodies with basal ganglia tissue. The hypothesis of a possible involvement of the immunitary system seems justified from quantitative alterations of TNF-alpha, IL-6 and IL-1 in the patients' serum with such syndrome. Echotomographic studies on cardiac valves have not yet demonstrated the parallels between PANDAS and Sydenham's chorea. The use of treatment strategies, such as therapeutic plasmapheresis or intravenous immunoglobulin, has been proposed to explain the autoimmune process responsible for the pathogenesis of PANDAS. Further research is still necessary in order to understand the role of streptococcal infection in the pathogenesis of PANDAS. PMID:20066816

  12. Modelling of particular phenomena observed in PANDA with Gothic

    International Nuclear Information System (INIS)

    PANDA is a large scale facility for investigating the long-term decay heat removal from the containment of a next generation 'passive' Advanced Light Water Reactor (ALWR). The first test series was aimed at the investigation of the long-term LOCA response of the Passive Containment Cooling System (PCCS) for the General Electric (GE) Simplified Boiling Water Reactor (SBWR). Recently, the facility is used in the framework of two European projects for investigating the performance of four passive cooling systems, i.e. the Building Condenser (BC) designed by Siemens for the SWR-1000 long-term containment cooling, the Passive Containment Cooling System for the European Simplified Boiling Water Reactor (ESBWR), the Containment Plate Condenser (CPC) and the Isolation Condenser (IC) for cooling of a BWR core. The PANDA tests have the dual objectives of improving confidence in the performance of the passive heat removal mechanisms underlying the design of the tested safety systems and extending the data base available for containment analysis code qualification. Among others, the containment analysis code Gothic was chosen for the analysis of particular phenomena observed during the PANDA tests. Ibis paper presents selected safety relevant phenomena observed in the PANDA tests and identified for the analyses and possible approaches for their modeling with Gothic. (author)

  14. GPU implementations of online track finding algorithms at PANDA

    International Nuclear Information System (INIS)

    The PANDA experiment is a hadron physics experiment that will investigate antiproton annihilation in the charm quark mass region. The experiment is now being constructed as one of the main parts of the FAIR facility. At an event rate of 2 . 107/s a data rate of 200 GB/s is expected. A reduction of three orders of magnitude is required in order to save the data for further offline analysis. Since signal and background processes at PANDA have similar signatures, no hardware-level trigger is foreseen for the experiment. Instead, a fast online event filter is substituting this element. We investigate the possibility of using graphics processing units (GPUs) for the online tracking part of this task. Researched algorithms are a Hough Transform, a track finder involving Riemann surfaces, and the novel, PANDA-specific Triplet Finder. This talk shows selected advances in the implementations as well as performance evaluations of the GPU tracking algorithms to be used at the PANDA experiment.

    The establishment of corridors can offset the negative effects of habitat fragmentation by connecting isolated habitat patches. However, the practical value of corridor planning is minimal if corridor identification is not based on reliable quantitative information about species-environment relationships. An example of this need for quantitative information is planning for giant panda conservation. Although the species has been the focus of intense conservation efforts for decades, most corridor projects remain hypothetical due to the lack of reliable quantitative researches at an appropriate spatial scale. In this paper, we evaluated a framework for giant panda forest corridor planning. We linked our field survey data with satellite imagery, and conducted species occupancy modelling to examine the habitat use of giant panda within the potential corridor area. We then conducted least-cost and circuit models to identify potential paths of dispersal across the landscape, and compared the predicted cost under current conditions and alternative conservation management options considered during corridor planning. We found that due to giant panda's association with areas of low elevation and flat terrain, human infrastructures in the same area have resulted in corridor fragmentation. We then identified areas with high potential to function as movement corridors, and our analysis of alternative conservation scenarios showed that both forest/bamboo restoration and automobile tunnel construction would significantly improve the effectiveness of corridor, while residence relocation would not significantly improve corridor effectiveness in comparison with the current condition. The framework has general value in any conservation activities that anticipate improving habitat connectivity in human modified landscapes. Specifically, our study suggested that, in this landscape, automobile tunnels are the best means to remove current barriers to giant panda movements caused by

    2015-05-01

    PANDA is an experiment that will run at the future facility FAIR, Darmstadt, Germany. A high intensity and cooled antiproton beam will collide on a fixed hydrogen or nuclear target covering center-of-mass energies between 2.2 and 5.5 GeV. PANDA addresses various physics aspects from the low energy non-perturbative region towards the perturbative regime of QCD. With the impressive theoretical developments in this field, e.g. lattice QCD, the predictions are becoming more accurate in the course of time. The data harvest with PANDA will, therefore, be an ideal test bench with the aim to provide a deeper understanding of hadronic phenomena such as confinement and the generation of hadron masses. A variety of physics topics will be covered with PANDA, for example: the formation or production of exotic non-qqbar charm meson states connected to the recently observed XYZ spectrum; the study of gluon-rich matter, such as glueballs and hybrids; the spectroscopy of the excited states of strange and charm baryons, their production cross section and their spin correlations; the behaviour of hadrons in nuclear matter; the hypernuclear physics; the electromagnetic proton form factors in the timelike region. The PANDA experiment is designed to achieve the above mentioned physics goals with a setup with the following characteristics: an almost full solid angle acceptance; excellent tracking capabilities with high resolution (1-2 % at 1 GeV/c in the central region); secondary vertex detection with resolution ≈ 100 microns or better; electromagnetic calorimetry for detections of gammas and electrons up to 10 GeV; good particle identification of charge tracks (electrons, muons, pions, kaons, protons); a dedicated interchangeable central apparatus for the hypernuclear physics; detector and data acquisition system capable of working at 20 MHz interaction rate with an intelligent software trigger that can provide maximum flexibility.

    To test the hypothesis of whether anogenital gland secretions (AGS) of giant panda code for their sexual ability, we collected AGS samples of 11 male (5 adult and 6 subadult) and 14 female (7adult and 7 subadult) captive giant pandas (Ailuropoda melanoleuca) from China Research and Conservation Center for the Giant Panda at Wolong, Sichuan, China from 1994 to 2002. The samples were analyzed by GC and GC-MS. The GC results showed that male and female pandas shared 20 constituents with equal capacity factors in the AGS. Further GC-MS analyses showed that there were a total of 95compounds in the AGS. Nine constituents for the males and three for the females differed significantly in relative abundances between sexually active and inactive individuals, but no clear division between sexually active and inactive pandas by hierarchical cluster analyses on the relative abundances of a subset of 56 compounds. However, we were able to separate different age groups of male pandas by the constituents of AGS. 14 compounds were found significantly and negatively, and 8 compounds positively,correlated with pandas' age by year. Our results suggest that the information contained in the AGS of panda might not code for pandas' sexual ability but might for their age. These results will be valuable for captive breeding and conservation in the wild.

    Dental data from eight adult giant pandas (Ailuropoda melanoleuca) (four females and four males) were collected at the Beijing Zoo from February 2009 to July 2010. Examination findings were recorded in dental charts. All the pandas had different degrees of tooth wear. Incisors, canines and second premolars had the most abnormalities. Five animals had caries; molars were the most affected. Chip fractures were found in seven teeth (incisor, canine and premolar) of five pandas; two had complicated fractures of their canines. Premolars and other teeth were missing in three pandas. Different degrees of dental plaque and calculus were found in all animals. Two pandas had mild gingivitis; the depth of periodontal pockets in all pandas was normal (0-2 mm). Five pandas had abnormal tooth mobility. Samples of dental plaque were collected for microbial culture. Two hundred and fifty-three bacterial strains belonging to 48 species of 23 genera were isolated. Streptococcus, Moraxella, Peptostreptococcus and Porphyromonas were the dominant genera. Further research with larger sample sizes of free-ranging and captive giant pandas will be required in order to demonstrate the absence of the premolar tooth, tooth fractures and the relatively low prevalence of periodontal disease in captive giant pandas.

    Full Text Available Background: Parenteral nutrition-associated liver dysfunction can be progressive and irreversible, particularly in children and patients with long-term treatment. This study has assessed the incidence of abnormal liver function tests in hospitalized adults during short term parenteral nutrition (PN and has investigated risk factors for developing alterations of each parameter. Methods: A prospective cohort study of parenteral nutrition treated patients with preserved liver function at baseline. Variables examined included nutritional and clinical data and laboratory parameters. Determinations were performed before starting PN and weekly until liver function test alteration was observed. Risk factors were investigated by four stepwise forward logistical regressions. Results: Eighty patients were included, 57.5% had liver function test alterations. PN mean duration was 15.9 (8-54 days. Mean days with PN and additional enteral/ oral nutrition were 1.5 (0-20. The following associations were found: gamma-glutamyl-transferase increased with soybean lipid intake and absolute diet; alkaline phosphatase increased with septic shock; alanine transaminase increased with septic shock, hyperglycemia and elevated creatinine; total bilirubin increased with septic shock, absolute diet, low prealbumin and glucose, and high creatinine. Conclusions: The incidence of altered liver function tests is high in adult hospitalized patients treated with short-term PN. However, the effect of nutritional factors in this alteration is low. Oral/enteral nutrition and reduction of soybean lipid supply can reduce increases in some liver function tests such as gamma-glutamyl-transferase and total bilirubin. The high association between all liver function tests and clinical systemic-hypermetabolic variables suggest the importance of specific nutritional strategies for this condition.Introducción: La alteración hepática asociada a la nutrición parenteral (NP puede ser

    PANDAS (Paediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infection) is a rare condition first described in 1998. It describes the presence of obsessive-compulsive disorder (OCD) or tics with an episodic course, and a temporal relationship to Group A beta haemolytic streptococcal infection (GABHS). Recurrent episodes can be disruptive and upsetting for a child, but the best way to treat the condition has yet to be established. Penicillin prophylaxis has not proved effective, and other therapies are experimental. There is some evidence in the literature to support the role of tonsillectomy in improving the condition. We report a case of a 6-year-old boy who presented with tic and hemi-chorea associated with GABHS throat infection. He had a recurrence of his symptoms associated with a further GABHS infection, but has had no further symptoms following tonsillectomy. This case report lends further evidence to the role of tonsillectomy in the management of PANDAS. PMID:16892924

    The PANDA experiment at the future Facility for Antiproton and Ion Research (FAIR) requires excellent particle identification. Two different DIRC detectors will utilize internally reflected Cherenkov light of charged particles to enable the separation of pions and kaons up to momenta of 4 GeV/c. The Endcap Disc DIRC will be placed in the forward endcap of PANDA's central spectrometer covering polar angles between 5° and 22°. Its final design is based on MCP-PMTs for the photon detection and an optical system made of fused silica. A new prototype has been investigated during a test beam at CERN in May 2015 and first results will be presented. In addition a new synthetic fused silica material by Nikon has been tested and was found to be radiation hard.

  11. FPGA based compute nodes for high level triggering in PANDA

    International Nuclear Information System (INIS)

    PANDA is a new universal detector for antiproton physics at the HESR facility at FAIR/GSI. The PANDA data acquisition system has to handle interaction rates of the order of 107/s and data rates of several 100 Gb/s. FPGA based compute nodes with multi-Gb/s bandwidth capability using the ATCA architecture are designed to handle tasks such as event building, feature extraction and high level trigger processing. Data connectivity is provided via optical links as well as multiple Gb Ethernet ports. The boards will support trigger algorithms such us pattern recognition for RICH detectors, EM shower analysis, fast tracking algorithms and global event characterization. Besides VHDL, high level C-like hardware description languages will be considered to implement the firmware

    Two neonatal male red panda (Ailurus fulgens) littermates were submitted for necropsy examination. One animal was found dead with no prior signs of illness; the other had a brief history of laboured breathing. Post-mortem examination revealed disseminated protozoal infection. To further characterize the causative agent, transmission electron microscopy (TEM), immunohistochemistry (IHC), polymerase chain reaction (PCR) and amplification and nucleic acid sequencing were performed. IHC was negative for Toxoplasma gondii and Neospora caninum, but was positive for a Sarcocystis spp. TEM of cardiac muscle and lung revealed numerous intracellular apicomplexan protozoa within parasitophorous vacuoles. PCR and nucleic acid sequencing of partial 18S rRNA and the internal transcribed spacer (ITS)-1 region confirmed a Sarcocystis spp. that shared 99% sequence homology to Sarcocystis neurona and Sarcocystis dasypi. This represents the first report of sarcocystosis in red pandas. The histopathological, immunohistochemical, molecular and ultrastructural findings are supportive of vertical transmission resulting in fatal disseminated disease. PMID:26054654

    International Nuclear Information System (INIS)

    The electromagnetic calorimeter of the target spectrometer of PANDA relies on the high quality of Scintillator material PbWO4. In collaboration with the manufacturer BTCP at Bogoroditsk (Tula district, Russia) a new standard PWO-II was developed. After the approval of the Technical Design Report the final mass production for the forward endcap and part of the barrel has been started immediately. The first stage of quality control, which covers the geometrical dimensions, optical and scintillation properties, is performed similar to the CMS/ECAL project exploiting the semi-automatic robot ACCOS at CERN. The radiation hardness is tested for each crystal at the 60Co irradiation facility at Giessen to guarantee the optimum performance at the final operating temperature of T=-25 C. The report describes in detail the test procedures and summarizes the achieved quality in comparison to the required specification limits for PANDA.

    This document describes the technical layout and the expected performance of the Straw Tube Tracker (STT), the main tracking detector of the PANDA target spectrometer. The STT encloses a Micro-Vertex-Detector (MVD) for the inner tracking and is followed in beam direction by a set of GEM-stations. The tasks of the STT are the measurement of the particle momentum from the reconstructed trajectory and the measurement of the specific energy-loss for a particle identification. Dedicated simulations with full analysis studies of certain proton-antiproton reactions, identified as being benchmark tests for the whole \\Panda scientific program, have been performed to test the STT layout and performance. The results are presented, and the time lines to construct the STT are described.

    We report on plans for a multiplexed neutron analyser option for the PANDA spectrometer. The key design concept is to have many analysers positioned to give a large coverage in the scattering plane, and multiple arcs of these analysers to measure different energy transfers simultaneously. The main goal is to bring intensity gains and improved reciprocal-space and energy mapping capabilities to the existing cold triple-axis spectrometer.

    We report the long term performance of the photosensors, 143 one-inch R8520-406 and 37 three-inch R11410-MOD photomultipliers from Hamamatsu, in the first phase of the PandaX dual-phase xenon dark matter experiment. This is the first time that a significant number of R11410 photomultiplier tubes were operated in liquid xenon for an extended period, providing important guidance to the future large xenon-based dark matter experiments.

    Mirror self-recognition (MSR), i.e., the ability to recognize oneself in a mirror, is considered a potential index of self-recognition and the foundation of individual development. A wealth of literature on MSR is available for social animals, such as chimpanzees, Asian elephants and dolphins, yet little is known about MSR in solitary mammalian species. We aimed to evaluate whether the giant panda can recognize itself in the mirror, and whether this capacity varies with age. Thirty-four captive giant pandas (F:M = 18:16; juveniles, sub-adults and adults) were subjected to four mirror tests: covered mirror tests, open mirror tests, water mark control tests, and mark tests. The results showed that, though adult, sub-adult and juvenile pandas exposed to mirrors spent similar amounts of time in social mirror-directed behaviors (χ(2) = 0.719, P = 0.698), none of them used the mirror to touch the mark on their head, a self-directed behavior suggesting MSR. Individuals of all age groups initially displayed attacking, threatening, foot scraping and backwards walking behaviors when exposed to their self-images in the mirror. Our data indicate that, regardless of age, the giant pandas did not recognize their self-image in the mirror, but instead considered the image to be a conspecific. Our results add to the available information on mirror self-recognition in large mammals, provide new information on a solitary species, and will be useful for enclosure design and captive animal management.

  18. Improving Security in the ATLAS PanDA System

    International Nuclear Information System (INIS)

    The security challenges faced by users of the grid are considerably different to those faced in previous environments. The adoption of pilot jobs systems by LHC experiments has mitigated many of the problems associated with the inhomogeneities found on the grid and has greatly improved job reliability; however, pilot jobs systems themselves must then address many security issues, including the execution of multiple users' code under a common 'grid' identity. In this paper we describe the improvements and evolution of the security model in the ATLAS PanDA (Production and Distributed Analysis) system. We describe the security in the PanDA server which is in place to ensure that only authorized members of the VO are allowed to submit work into the system and that jobs are properly audited and monitored. We discuss the security in place between the pilot code itself and the PanDA server, ensuring that only properly authenticated workload is delivered to the pilot for execution. When the code to be executed is from a 'normal' ATLAS user, as opposed to the production system or other privileged actor, then the pilot may use an EGEE developed identity switching tool called gLExec. This changes the grid proxy available to the job and also switches the UNIX user identity to protect the privileges of the pilot code proxy. We describe the problems in using this system and how they are overcome. Finally, we discuss security drills which have been run using PanDA and show how these improved our operational security procedures.

  19. The PANDA detector and its physics program at FAIR

    International Nuclear Information System (INIS)

    The PANDA detector will make use of the antiprotons produced in the FAIR complex and stored in the High-Energy Storage Ring HESR for the study of strong interactions in antiproton collisions with protons and heavy targets. The detector features a 4π design for charged particles with a solenoidal magnetic field and full coverage of photons by means of an advanced electromagnetic calorimeter. In addition, a dipole spectrometer will allow high-resolution detection of leading particles characteristic for fixed-target experiments. The physics program of PANDA covers a wide range of topics which address central issues of QCD at low and moderate energies. Spectroscopy of hidden charm in the ccbar level scheme is still a very interesting issue, in particular when states are involved which cannot directly be formed in e+e- reactions. Open charm in the D meson section has recently received renewed interest when states were discovered that are not easily explained in conventional qqbar models. Exotic hadrons and glueballs have been predicted by theory within the energy range covered by PANDA. The search for these and the eventual study of their properties is central to the physics program. Using heavy targets, PANDA intends to study the properties of charm quarks in the hadronic medium. The copious production of baryon-antibaryon pairs at HESR will allow studies using secondary targets for the formation of hypernuclei. Each of these physics topics will be touched while the detector properties needed in order to cover the broad physics program are described. Technical developments and the status of the various detector components will be summarized

    The PanDA Production and Distributed Analysis system is handling the ATLAS workload management for production and distributed analysis processing. It was designed for analysis as well as production for High Energy Physics. One of the advantages of this pilot based system is, that it has its own integrated monitoring solution. Monitoring is a method used in computing, it means that a certain process is observed and overseen and is usually also protocolled. In the case of a process or system failure, a responsible person should be notified and countermeasures taken. Since PanDA is very versatile, it can also be used to process jobs on a computing Cloud, instead of just using the Grid(WLCG). Cloud computing resources can be provided by private companies, that bill the resources that are actually being used, for example CPU power over time. The advantage of this is obvious if one looks at the cost. They are basically the same, whether a huge task is done on little CPU power over a long time or on plenty of CPU power in a short time. For these reasons, a close monitoring, for example by the PanDA system for the usage of Cloud resources is important.

    We identified the winter plant species consumed by red panda in the Dhorpatan Hunting Reserve of eastern Nepal and compared this to the early-summer diet which was determined previously by Panthi et al. (2012). In addition, we estimated the proximate nutritional content of the leaves identified in red panda diet for both seasons, and we used nutritional geometry to explore macronutrient balance of leaves from the two different sampling periods. We identified six different plants in winter scats, which were the same as found in the previously determined early-summer diet. Arundinaria spp. bamboos were the main species found (82.1 % relative frequency), followed by Acer spp. (6.3 %), Betula utilis (4.6 %), Quercus semicarpifolia (3.7 %), Berberis spp. (1.3 %), and lichens (1.0 %), leaving 2.0 % unidentified. Geometric analysis suggested that the macronutrient balance of seasonal diets were similar in nutrient balance to the most frequently consumed Arundinaria spp. Differences in macronutrient balance may indicate seasonal nutrient preferences, such as increased carbohydrate intake in winter for thermogenesis, and increased protein and lipid intake in early summer to support reproduction and lactation; however, these differences may also indicate differences in resource availability. Habitat conserved for red panda in the region should include sufficient Arundinaria spp. as well as lesser consumed plants which may serve as complimentary foods.

    Chemical communication plays an important role in kin selection and mate choice in mammals. The covariance of odor-genes of rodents has been documented and kinship odor has been proposed and termed, yet little is known of the relationship between genetic relatedness and chemical composition of kinship odors. Giant pandas (Ailuropoda melanoleuca) rely substantially on chemical communication to mediate their social interactions. To examine the relationship between genetic relatedness and compounds in the urine/anogenital gland secretions, we compared the similarities between genetic relatedness and the chemical profiles of anogenital gland secretions and urine via lineage construction and GC-MS (gas chromatography and mass spectrometry). We found that information about kinship odors was present only in the urine of male adults in the mating season but absent in the non-mating season. Adult females and all sub-adults did not have such kinship odors in either mating or non-mating season. Therefore, kinship odor in the panda was contingent on age, sex, and season. This is the first report about the condition-dependent expression of kinship odor, which may have a sig-nificant implication in the practice of panda conservation in relation to chemical communication and sexual selection.

    The PANDA collaboration at FAIR will employ antiproton annihilations to investigate yet undiscovered charm-meson states and glueballs. The aim is to study QCD phenomena in the non-perturbative regime and to unravel the origin of hadronic masses. A multi-purpose detector for tracking, calorimetry and particle identification is presently being developed to run at high luminosities providing up to 2.10{sup 7} interactions/s. One of the crucial components of the PANDA spectrometer is the EMC, composed of cooled PbWO{sub 4} crystals coupled to the Large Area Avalanche Photodiodes or Vacuum Photo-Triodes/Tetrodes. The photo-sensor signals are continuously digitized by the Sampling ADC (SADC) and analyzed on-line in the FPGA of the digitizer module to detect hits and extract energy and time information. Measurements with a prototype calorimeter were performed at the tagged-photon facility at MAMI-C, Mainz. The results demonstrate the excellent performance of the SADC readout, with energy resolutions better than achieved by analogue electronics and a sub-nanosecond time resolution. A fast on-line pile-up recovery algorithm has been developed. The layout of the complete digital read-out chain is presented, and results from applications in test experiments with the PANDA-EMC prototypes are reported.

    An important foundation underlying the impressive success of data processing and analysis in the ATLAS experiment [1] at the LHC [2] is the Production and Distributed Analysis (PanDA) workload management system [3]. PanDA was designed specifically for ATLAS and proved to be highly successful in meeting all the distributed computing needs of the experiment. However, the core design of PanDA is not experiment specific. The PanDA workload management system is capable of meeting the needs of other data intensive scientific applications. Alpha-Magnetic Spectrometer [4], an astro-particle experiment on the International Space Station, and the Compact Muon Solenoid [5], an LHC experiment, have successfully evaluated PanDA and are pursuing its adoption. In this paper, a description of the new program of work to develop a generic version of PanDA will be given, as well as the progress in extending PanDA's capabilities to support supercomputers and clouds and to leverage intelligent networking.

    The independent dietary shift from carnivore to herbivore with over 90% being bamboo in the giant and the red pandas is of great interests to biologists. Although previous studies have shown convergent evolution of the giant and the red pandas at both morphological and molecular level, the evolution of the gut microbiota in these pandas remains largely unknown. The goal of this study was to determine whether the gut microbiota of the pandas converged due to the same diet, or diverged. We characterized the fecal microbiota from these two species by pyrosequencing the 16S V1-V3 hypervariable regions using the 454 GS FLX Titanium platform. We also included fecal samples from Asian black bears, a species phylogenetically closer to the giant panda, in our analyses. By analyzing the microbiota from these 3 species and those from other carnivores reported previously, we found the gut microbiotas of the giant pandas are distinct from those of the red pandas and clustered closer to those of the black bears. Our data suggests the divergent evolution of the gut microbiota in the pandas. PMID:25985413

  10. Seasonal changes of progesterone and testosterone contents in hair of giant pandas

    International Nuclear Information System (INIS)

    Seasonal changes of progesterone content (PSC) in hair of three female giant pandas and testosterone content (TSC) in hair of two male giant pandas were tested by radioimmunoassay. During March to early June, PSC in two non-pregnant giant pandas (x-bar+-SD = 13.40 +- 10.06 and 10.60 +- 8.88 ng/g hair respectively) were higher than those in non-breeding season (3.07 +-1.07 and 3.20 +- 1.15 ng/g, P<0.01). PSC in a 18-year-old female giant panda remained at low levels (2.72 +- 1.49 ng/g) during March to December. In a twin-bear giant panda, PSC (6.77 +- 3.66 ng/g) appeared higher than that in non-pregnant giant pandas in non-breeding season. Around February to the end of May, TSC in two male giant pandas (1.89 +- 1.71 and 1.82 +- 1.04 ng/g respectively) were also higher than that in non-breeding season (0.98 +- 0.57 and 0.75 +- 0.39 ng/g, P<0.01). the findings from the study implied that giant panda's hair is possible to be used as a specimen to carry out steroids research in the endangered species

  11. Evolution of the ATLAS PanDA workload management system for exascale computational science

    International Nuclear Information System (INIS)

    An important foundation underlying the impressive success of data processing and analysis in the ATLAS experiment [1] at the LHC [2] is the Production and Distributed Analysis (PanDA) workload management system [3]. PanDA was designed specifically for ATLAS and proved to be highly successful in meeting all the distributed computing needs of the experiment. However, the core design of PanDA is not experiment specific. The PanDA workload management system is capable of meeting the needs of other data intensive scientific applications. Alpha-Magnetic Spectrometer [4], an astro-particle experiment on the International Space Station, and the Compact Muon Solenoid [5], an LHC experiment, have successfully evaluated PanDA and are pursuing its adoption. In this paper, a description of the new program of work to develop a generic version of PanDA will be given, as well as the progress in extending PanDA's capabilities to support supercomputers and clouds and to leverage intelligent networking. PanDA has demonstrated at a very large scale the value of automated dynamic brokering of diverse workloads across distributed computing resources. The next generation of PanDA will allow other data-intensive sciences and a wider exascale community employing a variety of computing platforms to benefit from ATLAS' experience and proven tools.

    The PanDA (Production and Distributed Analysis system was developed in 2005 for the ATLAS experiment on top of this heterogeneous infrastructure to seamlessly integrate the computational resources and give the users the feeling of a unique system. Since its origins, PanDA has evolved together with upcoming computing paradigms in and outside HEP, such as changes in the networking model, Cloud Computing and HPC. It is currently running steadily up to 200 thousand simultaneous cores (limited by the available resources for ATLAS, up to two million aggregated jobs per day and processes over an exabyte of data per year. The success of PanDA in ATLAS is triggering the widespread adoption and testing by other experiments. In this contribution we will give an overview of the PanDA components and focus on the new features and upcoming challenges that are relevant to the next decade of distributed computing workload management using PanDA.

  15. Habitat correlates of the red panda in the temperate forests of Bhutan.

    Directory of Open Access Journals (Sweden)

    Sangay Dorji

    Full Text Available Anthropogenic activities and associated global climate change are threatening the biodiversity in the Himalayas against a backdrop of poor knowledge of the region's threatened species. The red panda (Ailurus fulgens is a threatened mammal confined to the eastern Himalayas, and because of Bhutan's central location in the distributional range of red pandas, its forests are integral to the long-term viability of wild populations. Detailed habitat requirements of the red panda are largely speculative, and there is virtually no ecological information available on this species in Bhutan. Between 2007 and 2009, we established 615 presence/absence plots in a systematic sampling of resident habitat types within Jigme Dorji and Thrumshingla National Parks, Bhutan, to investigate broad and fine-scale red panda habitat associations. Additional locality records of red pandas were obtained from interviewing 664 park residents. Red pandas were generally confined to cool broadleaf and conifer forests from 2,110-4,389 m above sea level (asl, with the majority of records between 2,400-3,700 m asl on south and east-facing slopes. At a finer scale, multivariate analysis revealed that red pandas were strongly associated with old growth Bhutan Fir (Abies densa forest dominated by a dense cover of Yushania and Arundanaria bamboo with a high density of fallen logs and tree stumps at ground level; a high density of trees, dead snags, and rhododendron shrubs in the mid-storey; and locations that were close to water. Because Bhutan's temperate forests that encompass prime red panda habitat are also integral to human subsistence and socio-economic development, there exists an inadvertent conflict between the needs of people and red pandas. As such, careful sustainable management of Bhutan's temperate forests is necessary if a balance is to be met between the socioeconomic needs of people and the conservation goals for red pandas.

  16. Microbial diversity and evidence of novel homoacetogens in the gut of both geriatric and adult giant pandas (Ailuropoda melanoleuca.

    Full Text Available Recent studies have described the bacterial community residing in the guts of giant pandas, together with the presence of lignocellulolytic enzymes. However, a more comprehensive understanding of the intestinal microbial composition and its functional capacity in giant pandas remains a major goal. Here, we conducted a comparison of bacterial, fungal and homoacetogenic microbial communities from fecal samples taken from two geriatric and two adult captive giant pandas. 16S rDNA amplicon pyrosequencing revealed that Firmicutes and Proteobacteria are the most abundant microbiota in both geriatric and adult giant pandas. However, members of phylum Actinobacteria found in adult giant pandas were absent in their geriatric counterparts. Similarly, ITS1 amplicon pyrosequencing identified developmental changes in the most abundant fungal classes from Sordariomycetes in adult pandas to Saccharomycetes in geriatric pandas. Geriatric pandas exhibited significantly higher abundance of a potential probiotic fungus (Candida tropicalis as compared to adult pandas, indicating their importance in the normal digestive physiology of aged pandas. Our study also reported the presence of a lignocellulolytic white-rot fungus, Perenniporia medulla-panis, and the evidence of novel homoacetogens residing in the guts of giant pandas.

  19. Post-test analyses of PANDA Test P7

    International Nuclear Information System (INIS)

    The TEPSS project (Technology Enhancement for Passive Safety Systems) is a part of the European Research Framework Program. The objective of TEPSS project is to make significant additions to the technology related to advanced passive type Boiling Water Reactor (BWR) designs. Work Package 2 of the TEPSS project is concentrated on the PANDA test facility (Passive Decay Heat Removal and Depressurization Test Facility). The facility has been constructed at the Paul Scherrer Institute, Switzerland. A series of experiments (the P-series tests) has been performed at the PANDA facility within the TEPSS project. This report contains results of the post-test analytical simulation of the PANDA Integrated System Test P7. Simulations have been performed using the following computer codes: MELCOR 1.8.3, RELAP5/Mod3.2, TRAC-BF 1. Results of the calculations are compared to the measured data. Generally the results obtained with the codes are m agreement with experimental data. Sources of discrepancies between code results and experimental data are well understood. It has been observed that 'lumped parameter' codes, e.g. MELCOR, may have troubles if large degree of stratification develops in some parts of the system. On the other hand 'field codes', e.g. RELAP or TRAC, can only represent single non-condensable gas, which leads to troubles when a light gas (in case of P7 helium) is injected into steam-air atmosphere. In case of the TRAC code, a full scope analysis of the P7 test was not possible because of numerical problems. Only part of the system was modelled. It is therefore concluded that the MELCOR and RELAP codes can be used to simulate the behaviour of BWR containment with passive decay heat removal systems. Troubles encountered during TRAC-BF1 simulation make it doubtful whether the code is a useful tool for this kind of analysis. 16 refs

    In order to survey the infectious situation of canine coronavirus (CCV) in giant panda population, a virus neutralization test detecting specific antibodies against CCV in giant panda's sera was established by using two-fold dilutions of serum and 100 TCID50 of the virus. The 62 sera samples of giant pandas, which were gathered from zoos and reserve region of Sichuan Province, China were detected. The neutralization antibody titer of 1:4 was recognized as the positive criterion, 8 sera samples were detected to be positive, and the positive rate was 12.9%. The titers of neutralizing antibody ranged from 1:8 to 1:32. It was the first comprehensive investigation on neutralization antibodies against CCV in giant panda population in China. The results of study showed that the infection of CCV in giant panda population was universal, which has posed a threat to the health of giant panda. Therefore, it is incumbent on us to study safe and effective vaccines to protect giant panda against CCV infection.

    Understanding the impacts of meteorological factors on giant pandas is necessary for future conservation measures in response to global climate change. We integrated temperature data with three main habitat parameters (elevation, vegetation type, and bamboo species) to evaluate the influence of climate change on giant panda habitat in the northern Minshan Mountains using a habitat assessment model. Our study shows that temperature (relative importance = 25.1%) was the second most important variable influencing giant panda habitat excepting the elevation. There was a significant negative correlation between temperature and panda presence (ρ = -0.133, P problems in the northwest Minshan Mountains, which means that giant pandas can adapt to climate change, and therefore may be resilient to climate change. Thus, for the safety and survival of giant pandas in the Baishuijiang Reserve, we propose strengthening the giant panda monitoring program in the west and improving the integrity of habitats to promote population dispersal with adjacent populations in the east.

However, instrumentation has advances far beyond expectations and now we are able to generate data faster than it can be interpreted. Materials and Methods. We have developed PANDA (Pathway AND Annotation Explorer, a visualization tool that integrates gene-level annotation in the context of biological pathways to help interpret complex data from disparate sources. PANDA is a web-based application that displays data in the context of well-studied pathways like KEGG, BioCarta, and PharmGKB. PANDA represents data/annotations as icons in the graph while maintaining the other data elements (i.e., other columns for the table of annotations. Custom pathways from underrepresented diseases can be imported when existing data sources are inadequate. PANDA also allows sharing annotations among collaborators. Results. In our first use case, we show how easy it is to view supplemental data from a manuscript in the context of a user’s own data. Another use-case is provided describing how PANDA was leveraged to design a treatment strategy from the somatic variants found in the tumor of a patient with metastatic sarcomatoid renal cell carcinoma. Conclusion. PANDA facilitates the interpretation of gene-centric annotations by visually integrating this information with context of biological pathways.

    The technical design of the PANDA experiment at the future FAIR facility next to GSI is progressing. At the proposed anti-proton storage ring the spectroscopy of double Lambda hypernuclei is one of the four main topics which will be addressed by the Collaboration. The hypernuclear experiments require (i) a dedicated internal target, (ii) an active secondary target of alternating silicon and absorber material layers, (iii) high purity germanium (HPGe) detectors, and (iv) a good particle identification system for low momentum kaons. All systems need to operate in the presence of a high magnetic field and a large hadronic background. The status of the detector developments for this programme is summarized.

  13. ComPWA: A common amplitude analysis framework for PANDA

    International Nuclear Information System (INIS)

    A large part of the physics program of the PANDA experiment at FAIR deals with the search for new conventional and exotic hadronic states like e.g. hybrids and glueballs. For many analyses PANDA will need an amplitude analysis, e.g. a partial wave analysis (PWA), to identify possible candidates and for the classification of known states. Therefore, a new, agile and efficient amplitude analysis framework ComPWA is under development. It is modularized to provide easy extension with models and formalisms as well as fitting of multiple datasets, even from different experiments. Experience from existing PWA programs was used to fix the requirements of the framework and to prevent it from restrictions. It will provide the standard estimation and optimization routines like Minuit2 and the Geneva library and be open to insert additional ones. The challenges involve parallelization, fitting with a high number of free parameters, managing complex meta-fits and quality assurance / comparability of fits. To test and develop the software, it will be used with data from running experiments like BaBar or BESIII. These proceedings show the status of the framework implementation as well as first test results.

    China faces strong air pollution problems related to rapid economic development in the past decade and increasing demand for energy. Air quality monitoring stations often report high levels of particle matter and ozone all over the country. Knowing its long-term health impacts, air pollution became then a pressing problem not only in China but also in other Asian countries. The PANDA project is a result of cooperation between scientists from Europe and China who joined their efforts for a better understanding of the processes controlling air pollution in China, improve methods for monitoring air quality and elaborate indicators in support of European and Chinese policies. A modeling system of air pollution is being setup within the PANDA project and include advanced global (MACC, EMEP) and regional (WRF-Chem, EMEP) meteorological and chemical models to analyze and monitor air quality in China. The poster describes the accomplishments obtained within the first year of the project. Model simulations for January and July 2010 are evaluated with satellite measurements (SCIAMACHY NO2 and MOPITT CO) and in-situ data (O3, CO, NOx, PM10 and PM2.5) observed at several surface stations in China. Using the WRF-Chem model, we investigate the sensitivity of the model performance to emissions (MACCity, HTAPv2), horizontal resolution (60km, 20km) and choice of initial and boundary conditions.

    2015-02-01

    The PANDA experiment at the new FAIR facility will cover a broad experimental programme in hadron structure and spectroscopy. As a multipurpose detector, the PANDA spectrometer needs to ensure almost 4π coverage of the scattering solid angle, full and accurate multiple-particle event reconstruction and very good particle identification capabilities. The electromagnetic calorimeter (EMC) will be a key item for many of these aspects. Particle energies ranging from some MeVs to several GeVs have to be measured with a relative resolution of 1% ⊕ 2%/√E/GeV . It will be a homogeneous calorimeter made of PbWO4 crystals and will be operated at -25°C, in order to improve the scintillation light yield. With the exception of the very forward section, the light will be detected by large area avalanche photodiodes (APDs). The current pulses from the APDs will be integrated, amplified and shaped by ASIC chips which were developed for this purpose. The whole calorimeter has been designed in three sections: a forward end-cap, a central barrel and a backward end-cap (BWEC). In this contribution, a status report on the development of the BWEC is presented.

    The PANDA experiment will be part of the future Facility for Antiproton and Ion Research (FAIR) and aims for the study of strong interaction within the charm sector via antiproton proton collisions up to antiproton momenta of 15 GeV/c. Reflecting the variety of the physics program the PANDA detector is designed as a multi-purpose detector able to perform tracking, calorimetry and particle identification with nearly complete coverage of the solid angle. The Electromagnetic Calorimeter (EMC) contained inside its Target Spectrometer is based on cooled PbWO4 scintillator crystals. In order to ensure an excellent performance throughout the large dynamic range of photon/electron energies ranging from a few MeV up to 15 GeV an extensive prototyping phase is mandatory. This contribution describes the measured response of the EMC barrel part prototype PROTO60 at the largest design energy to secondary beams provided by the SPS at CERN. In addition to PROTO60 a tracking station was deployed, providing precise position information of the 15 GeV/c positrons. For calibration purposes a 150 GeV/c muon beam and cosmic radiation, in combination with estimations from GEANT4 simulations were used. The obtained performance concerning energy, position and time information is presented.

  17. ATLAS World-cloud and networking in PanDA

    CERN Document Server

    Barreiro Megino, Fernando Harald; The ATLAS collaboration

    2016-01-01

    The ATLAS computing model was originally designed as static clouds (usually national or geographical groupings of sites) around the Tier 1 centers, which confined tasks and most of the data traffic. Since those early days, the sites' network bandwidth has increased at O(1000) and the difference in functionalities between Tier 1s and Tier 2s has reduced. After years of manual, intermediate solutions, we have now ramped up to full usage of World-cloud, the latest step in the PanDA Workload Management System to increase resource utilization on the ATLAS Grid, for all workflows (MC production, data (re)processing, etc.). We have based the development on two new site concepts. Nuclei sites are the Tier 1s and large Tier 2s, where tasks will be assigned and the output aggregated, and satellites are the sites that will execute the jobs and send the output to their nucleus. Nuclei and satellite sites are dynamically paired by PanDA for each task based on the input data availability, capability matching, site load and...

  18. Towards a GEM-based TPC for PANDA

    International Nuclear Information System (INIS)

    A Time Projection Chamber (TPC) is a very promising option for the central tracker of the PANDA experiment at the new Facility for Antiproton and Ion Research (FAIR) at Darmstadt, Germany. Installed in a ring-type experiment with 2 x 107 p anti p annihilations per second it has to be operated continuously despite the presence of space charge effects. These are kept at a bearable level using GEM-based amplification providing an intrinsic suppression of ion backflow. The system promises high-accuracy tracking as well as information on the specific energy-loss and features high momentum resolution of 1% as well as particle-identification capability with a highly homogeneous and low material budget. As a prototype of a PANDA TPC a large-volume detector with a ring-cylindrical shape of the drift volume with diameters of 10/30 cm and 73 cm length has been set up. A triple-GEM stack serves as an amplification stage. The signals of 10254 hexagonal pads are read out using front end cards based on the AFTER-T2K chip. Two copies of this system will be installed and employed in 2011 within both the FOPI spectrometer at GSI and the Crystal-Barrel experiment at ELSA in Bonn. In this contribution, we will present the status of the project; report on the design and construction of the detector system as well as results obtained during the commissioning and first beam experiments.

    In nuclear detectors the information on the energy of the particle is usually obtained by measuring the amplitude of the signal delivered by the sensor. The low voltage power supply used in modern deep submicron technologies constrains the maximum dynamic range of the ADC. So we can obtain the energy information with time-based techniques, in which the energy is associated with the duration of the signal through the Time over Threshold method. This work is focused on the PANDA Micro Vertex Detector and explores the possibility of applying a time-based readout approach for the microstrip sensors. In PANDA, the strip system must cope with hit rates up to 50 kHz per channel. Therefore, the front-end output must be relatively short. This implies that the clock resolution is not enough to measure the signal duration, so it is necessary to use a Time to Digital Converter. The front-end and the TDC structure are designed in a 0.11μm CMOS process. The TDC chosen is based on an analog clock interpolator because it combines good time resolution with a fairly simple implementation and low power consumption. In the presentation the architectures are described and the challenges associated to its implementation discussed.

  20. Post-test analysis of PANDA test P4

    International Nuclear Information System (INIS)

    The results of a post-test analysis of the integral system test P4, which has been executed in the PANDA facility at PSI in Switzerland within the framework of Work Package 2 of the TEPSS project are presented. The post-test analysis comprises an evaluation of the PANDA test P4 and a comparison of the test results with the results of simulations using the RELAPS/MOD3.2, TRAC-BF1, and MELCOR 1.8.4 codes. The PANDA test P4 has provided data about how trapped air released from the drywell later in the transient affects PCCS performance in an adequate manner. The well-defined measurements can serve as an important database for the assessment of thermal hydraulic system analysis codes, especially for conditions that could be met in passively operated advanced reactors, i.e. low pressure and small driving forces. Based on the analysis of the test data, the test acceptance criteria have been met. The test P4 has been successfully completed and the instrument readings were with the permitted ranges. The PCCs showed a favorable and robust performance and a wide margin for decay heat removal from the containment. The PANDA P4 test demonstrated that trapped air, released from the drywell later in the transient, only temporarily and only slightly affected the performance of the passive containment cooling system. The analysis of the results of the RELAPS code showed that the overall behaviour of the test has been calculated quite well with regards to pressure, mass flow rates, and pool boil-down. This accounts both for the pre-test and the post-test simulations. However, due to the one-dimensional, stacked-volume modeling of the PANDA DW, WW, and GDCS vessels, 3D-effects such as in-vessel mixing and recirculation could not be calculated. The post-test MELCOR simulation showed an overall behaviour that is comparable to RELAPS. However, MELCOR calculated almost no air trapping in the PCC tubes that could hinder the steam condensation rate. This resulted in lower calculated

  1. ISP42 (PANDA Tests) - Open Phase Comparison Report

    International Nuclear Information System (INIS)

    PANDA is a large-scale facility, which has been constructed at the Paul Scherrer Institute (PSI) for the investigation of both overall dynamic response and the key phenomena of passive containment systems during the long-term heat removal phase for Advanced Light Water Reactors (ALWRs). Using a modular concept with a basic set of cylindrical vessels and connecting piping, the facility can be adapted to simulate different passive containment designs. Following a proposal, the OECD/NEA Committee on the Safety of Nuclear Installations approved, at its meeting on December 3-5, 1997, a new International Standard Problem (ISP) involving a test in the PANDA facility, based on a recommendation from the Principal Working Group 2 (PWG2) on System Behaviour. The main interest for this ISP is code validation in relation to a range of LWR and advanced LWR (ALWR) (mainly) containment issues that have been designated as important and involving thermalhydraulic phenomena. The ISP-PANDA test for defined six phases (A to F) was performed on 21/22 April 1998. Since the first part of ISP-42 was going to be conducted as a 'double- blind' or 'blind' exercise, the experimental data was locked. The 'blind' phase calculational results compared to experimental data are presented in the report entitled 'ISP-42 (PANDA Tests ) Blind Phase Comparison'. In the second part, the 'open' exercise has been conducted by providing the ISP-42 PANDA test data to the participants and by performing post-test analysis. The results of the 'open' phase are presented in the present report. 'Open' phase submissions, comparisons, and analyses for ISP-42 are based on the outcome of the results presented in the 'blind' phase report of ISP-42. The experimental data was distributed to all ISP-42 participants for their post-test calculations, 20 June 2000. 'Open' phase analyses of some of the ISP-42 participants, were completely received by the end of January 2001. There were 27 new submissions for different phases

    2015-01-01

    Charm and charmonium physics have gained renewed interest in the past decade. Recent spectroscopic observations strongly motivate these studies. Among the several possible reactions, measurements in proton-antiproton annihilation play an important role, complementary to the studies performed at B-factories. The fixed target PANDA experiment at FAIR (Darmstadt, Germany) will investigate fundamental questions of hadron and nuclear physics in the interactions of antiprotons with nucleons and nuclei. With reaction rates as large as 2*10^7 interactions/s, and a mass resolution 20 times better as compared with the most recent B-factories, PANDA is in a privileged position to successfully perform the measurement of the width of narrow states, such as the X(3872). PANDA will investigate also high spin particles, whose observation was forbidden at B-factories, i.e. F-wave charmonium states. In this report extrapolations on cross sections and rates with PANDA are given.

    We report the results of a weakly-interacting massive particle (WIMP) dark matter search using the full 80.1\\;live-day exposure of the first stage of the PandaX experiment (PandaX-I) located in the China Jin-Ping Underground Laboratory. The PandaX-I detector has been optimized for detecting low-mass WIMPs, achieving a photon detection efficiency of 9.6\\%. With a fiducial liquid xenon target mass of 54.0\\,kg, no significant excess event were found above the expected background. A profile likelihood analysis confirms our earlier finding that the PandaX-I data disfavor all positive low-mass WIMP signals reported in the literature under standard assumptions. A stringent bound on the low mass WIMP is set at WIMP mass below 10\\,GeV/c$^2$, demonstrating that liquid xenon detectors can be competitive for low-mass WIMP searches.

    Hyperon production is an excellent probe of QCD in the confinement domain, and spin observables are a powerful tool in understanding the underlying physics. For the Ω hyperon, seven polarisation parameters can be extracted from the angular distributions of its decay products with the future PANDA experiment at FAIR. Simulation studies reveal great prospects for strange and single charmed hyperon channels with PANDA. Software tools supporting these investigations are currently under development.

    Diagnosis and treatment of the PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections) variant of Gilles de la Tourette syndrome (GTS) and childhood-onset obsessive-compulsive disorder (OCD) are still controversial issues. Most cross-sectional studies confirm a significant association between GTS and the development of an immune response against group A beta-hemolytic streptococcus (GABHS). Moreover, longitudinal retrospective studies suggest that a recent exposure to GABHS might be a risk factor for the onset of tics and obsessive-compulsive symptoms. However, further evidence from longitudinal prospective research is needed to verify whether a temporal association between GABHS infections and symptom exacerbations is a useful and reliable criterion for the diagnosis of PANDAS. In addition, preliminary results suggest that the PANDAS spectrum might be enlarged to include attention deficit/hyperactivity disorder. Although a number of immunological biomarkers have been proposed as markers of the PANDAS variant, at present, none of these has been conclusively proved useful to diagnose and monitor disease course in children with a suspicion of PANDAS. Finally, despite their empirical use in community settings, we still lack conclusive, evidence-based data regarding the usefulness of antibiotic and immunomodulatory treatments in children with PANDAS. Given the relevance of this topic for general pediatric health, additional research efforts to solve all the pending issues and the hottest points of debate are warranted. PMID:19913659

    PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections) syndrome is a disorder seen before adolescence that possesses an abrupt onset of obsessive-compulsive disorder symptoms and/or tics. Swedo and colleagues defined this disorder in 1998 as a syndrome related to Group A streptoccoccus (GAS) infection with neurological issues, such as motor hyperactivation and choreiform movements. The progress of the disorder may be described as wax-and-waning, apart from abrupt onset, and this relapse and remission course is associated with exacerbating infections, according to the creators of PANDAS syndrome. Ruling out of Rheumatoid Fever and Sydenham's Chorea was a necessity for making a proper diagnosis. Since the recognition of this syndrome, clinicians encountered many children who could not fulfill all 5 criteria, which must be met for PANDAS diagnosis. In addition, due to literature showing failure and lack of strong evidence of a major role of GAS, the newly-defined categories PANS (Pediatric Acute-onset Neuropsychiatric Syndrome) and CANS (Childhood Acute Neuropsychiatric Syndrome) were created to encompass those of "almost met" non-PANDAS cases. PANS and CANS include concurrent significant psychiatric symptoms with abrupt onset of OCD symptoms and/or tics but do not require identification of any infection agent, immune dysfunction, or enviromental precipitants. In this paper, we aimed to discuss PANS/ CANS, alterations of PANDAS, and diagnoses in which "almost met" PANDAS patients should be classified on the basis of a case who developed an abrupt onset of anxiety, obsessions, and vocal tics.

    atrativo.The direct costs incurred in managing patients with poorly controlled asthma are high and educational programs could decrease these costs. Aim: The objectives of this study were to compare the direct cost of the implementation of an educational program for adult asthmatic patients with the cost of the usual care delivered to asthmatics by specialists. Methods: Five years ago, a six-month study demonstrated that an educational program improved clinical outcomes (22 in educational program-E and 20 patients in control group-C. Throughout the educational intervention period all cases of hospitalization, emergency and regular calls involving patients from both groups were recorded. The basis for the values utilized in the calculation of costs was the healthcare database of the Brazilian government (DATASUS. The overall medication cost/patient in both groups was based on the amount of medication taken during the month preceding the last call. The final values were converted into US dollars. Results: The mean direct cost/patient in the educational (E and control (C groups and the difference (delta between groups were: hospitalizations (C = US$ 183, E = 0, delta = US$ 183; emergency calls (C = US$ 14,E = US$ 5, delta = US$ 9; regular calls (C = US$ 10, E = US$ 24, delta = -US$ 14; medication (C = US$ 124,3, E = US$ 195,6, D or = -US$ 71,3. The total cost was US$ 33/patient in group C and US$ 224/patient in group E with an average cost saving of US$ 107/patient. Conclusion: The expenses with medication is higher in E group because the regular use of maintenance drugs, however the study suggested that the application of the asthma education program reduced the total direct costs of asthma.

  16. Why does the giant panda eat bamboo? A comparative analysis of appetite-reward-related genes among mammals.

    Directory of Open Access Journals (Sweden)

    Ke Jin

    Full Text Available BACKGROUND: The giant panda has an interesting bamboo diet unlike the other species in the order of Carnivora. The umami taste receptor gene T1R1 has been identified as a pseudogene during its genome sequencing project and confirmed using a different giant panda sample. The estimated mutation time for this gene is about 4.2 Myr. Such mutation coincided with the giant panda's dietary change and also reinforced its herbivorous life style. However, as this gene is preserved in herbivores such as cow and horse, we need to look for other reasons behind the giant panda's diet switch. METHODOLOGY/PRINCIPAL FINDINGS: Since taste is part of the reward properties of food related to its energy and nutrition contents, we did a systematic analysis on those genes involved in the appetite-reward system for the giant panda. We extracted the giant panda sequence information for those genes and compared with the human sequence first and then with seven other species including chimpanzee, mouse, rat, dog, cat, horse, and cow. Orthologs in panda were further analyzed based on the coding region, Kozak consensus sequence, and potential microRNA binding of those genes. CONCLUSIONS/SIGNIFICANCE: Our results revealed an interesting dopamine metabolic involvement in the panda's food choice. This finding suggests a new direction for molecular evolution studies behind the panda's dietary switch.

  20. A Triggerless readout system for the bar PANDA electromagnetic calorimeter

    2015-02-01

    One of the physics goals of the future bar PANDA experiment at FAIR is to research newly discovered exotic states. Because the detector response created by these particles is very similar to the background channels, a new type of data readout had to be developed, called "triggerless" readout. In this concept, each detector subsystem preprocesses the signal, so that in a later stage, high-level phyiscs constraints can be applied to select events of interest. A dedicated clock source using a protocol called SODANET over optical fibers ensures proper synchronisation between the components. For this new type of readout, a new way of simulating the detector response also needed to be developed, taking into account the effects of pile-up caused by the 20 MHz interaction rate.

    Hadronic particle identification (PID) in the barrel region of the PANDA experiment at the new Facility for Antiproton and Ion Research in Europe (FAIR) at GSI, Darmstadt will be provided by a DIRC (Detection of Internally Reflected Cherenkov light) counter. To optimize the performance and reduce the detector cost, detailed simulations of different design elements, such as the width of the radiators, the shape of the expansion volume, and the type of focusing system, were performed using Geant. Custom reconstruction algorithms were developed to match the detector geometry. We will discuss the single photon resolution and photon yield as well as the PID performance for the Barrel DIRC baseline design and several detector design options.

    Resonances in the charmonium mass region will be studied in antiproton annihilations at FAIR with the multi-purpose PANDA spectrometer providing measurements of electromagnetic signals in a wide dynamic range. The Sampling ADC (SADC) readout of the Electromagnetic Calorimeter (EMC) will allow to realize online hit-detection on the single-channel level and to derive time and energy information. A digital filtering and feature-extraction algorithm was developed and implemented in VHDL code for the online application in a commercial SADC. We discuss the readout scheme, the program logic, the precise signal amplitude detection with phase correction at low sampling frequencies, and the usage of a double moving-window deconvolution filter for the pulse-shape restoration. Such double filtering allows to operate the EMC at much higher rates and to minimize the amount of pile-up events.

    A novel FPGA based online tracking algorithm for helix track reconstruction in a solenoidal field, developed for the PANDA spectrometer, is described. Employing the Straw Tube Tracker detector with 4636 straw tubes, the algorithm includes a complex track finder, and a track fitter. Implemented in VHDL, the algorithm is tested on a Xilinx Virtex-4 FX60 FPGA chip with different types of events, at different event rates. A processing time of 7 $\\mu$s per event for an average of 6 charged tracks is obtained. The momentum resolution is about 3\\% (4\\%) for $p_t$ ($p_z$) at 1 GeV/c. Comparing to the algorithm running on a CPU chip (single core Intel Xeon E5520 at 2.26 GHz), an improvement of 3 orders of magnitude in processing time is obtained. The algorithm can handle severe overlapping of events which are typical for interaction rates above 10 MHz.

It will make use of a cooled, continuous antiproton beam (impinging on a hydrogen target) with momenta from 1.5 to 15 GeV/c, reaching a anti pp-annihilation rate of 2.107s-1. One option for the central tracker of the target spectrometer is a cylindrical, ungated, continuously running Time Projection Chamber (TPC) with GEM-based gas amplification stage. The chamber is designed to be 150 cm long with an outer radius of 41.5 cm and will be read out by ∝100.000 pickup electrodes. In this setup, several thousand tracks will be stored inside the TPC volume at any given time, leading to sustained data rates of ∝50 GB s-1 in the TPC alone. On top of such technical challenges, PANDA is designed to run without a 1st-level hardware trigger, making powerful online data processing indispensable. Most importantly, in order to filter out interesting signatures from the purely time-stamped track data and associate information from different detectors uniquely to distinct physics events, fast and efficient online pattern recognition methods will play a central role. Several methods, which are presently being studied - testing them on simulated data as well as data recently taken with a large GEM-TPC prototype (over 10.000 readout channels) - are discussed, complemented by first results from simulated and real events.

  6. Developments toward a silicon strip tracker for the PANDA experiment

    International Nuclear Information System (INIS)

    The PANDA detector at the future FAIR facility in Darmstadt will be a key experiment in the understanding of the strong interaction at medium energies where perturbative models fail to describe the quark-quark interaction. An important feature of the detector system is the ability to reconstruct secondary decay vertices of short-lived intermediate states by means of a powerful particle tracking system with the the Micro-Vertex Detector (MVD) as central element to perform high-resolution charmonium and open-charm spectroscopy. The MVD is conceived with pixel detectors in the inner parts and double-sided silicon strip detectors at the outer half in a very lightweight design. The PANDA detector system shall be operated in a self-triggering broadband acquisition mode. Implications on the read-out electronics and the construction of the front-end assemblies are analyzed and evaluation of prototype DSSD-detectors wrt. signal-to-noise ratio, noise figures, charge sharing behavior, spatial resolution and radiation degradation discussed. Methods of electrical sensor characterization with different measurement setups are investigated which may be useful for future large-scale QA procedures. A novel algorithm for recovering multiple degenerate cluster hit patterns of double-sided strip sensors is introduced and a possible architecture of a Module Data Concentrator ASIC (MDC) aggregating multiple front-end data streams conceived. A first integrative concept for the construction and assembly of DSSD modules for the barrel part of the MVD is introduced as a conclusion of the thesis. Furthermore, a detailed description of a simplified procedure for the calculation of displacement damage in compound materials is given as reference which was found useful for the retrieval of non-ionizing energy loss for materials other than silicon.

  7. Development of a GEM-based TPC for PANDA

    International Nuclear Information System (INIS)

    A Time Projection Chamber (TPC) is a very promising option for the central tracker of the PANDA experiment at the new Facility for Antiproton and Ion Research (FAIR) at Darmstadt, Germany. Installed in a ring-type experiment with 2x107 p anti p annihilations per second it has to be operated continuously despite the presence of space charge effects. These are kept at a bearable level using GEM-based amplification providing an intrinsic suppression of ion backflow. The system promises high-accuracy tracking as well as information on the specific energy-loss and features high momentum resolution of 1% as well as particle-identification capability with a highly homogeneous and low material budget. A test TPC with an active volume of 8 cm length and a diameter of 20 cm was operated in 2009 at the test-bench of the CB-ELSA experiment in Bonn. It served to investigate some of the relevant design features, the electronic foreseen for the readout as well as the analysis procedures. A large-volume TPC with a drift length of 70 cm and an active diameter of 30 cm is being built in parallel. Due to its very similar design it serves as a precursor prototype of a PANDA TPC. This detector is installed and employed within both the FOPI spectrometer at GSI and the Crystal-Barrel experiment at ELSA in Bonn. In this talk, we present the status of the project; report on the results obtained with the test detector as well as the design and construction of the GEM-TPC prototype.

    The pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) are basically characterized by obsessive-compulsive symptoms and/or tics triggered by group-A beta-hemolytic Streptococcus infections. Poor data are available about the clear definition of PANDAS's autoimmune origin. The aim of our study was to evaluate the prevalence of autoimmune phenomena, including thyroid function abnormalities, specific celiac disease antibodies, and positivity of organ- or nonorgan-specific autoantibodies in a large cohort of Caucasian children and adolescents with PANDAS. Seventy-seven consecutive patients (59 males, 18 females; mean age 6.3±2.5 years, range 2.0-14.5 years) strictly fulfilling the clinical criteria for PANDAS diagnosis were recruited. In all subjects we evaluated serum concentrations of free-T3, free-T4, thyrotropin, and the following auto-antibodies: anti-thyroperoxidase, anti-thyroglobulin, anti-thyrotropin receptor, anti-gliadin, anti-endomysium, anti-tissue transglutaminase, anti-nuclear, anti-smooth muscle, anti-extractable nuclear antigens, anti-phospholipid, plus lupus-like anticoagulant. The results were compared with those obtained from 197 age- and sex-matched healthy controls (130 males, 67 females; mean age 6.8±2.9 years, range 2.3-14.8 years). The frequencies of subclinical (3.8% vs 3.6%) and overt hypothyroidism (1.2% vs 0%), autoimmune thyroiditis (2.46% vs 1.14%), celiac disease (1.2% vs 0.05%), and positivity of organ- and nonorgan-specific autoantibodies (5.1% vs 4.8%) were not statistically significant between patients with PANDAS and controls. Evaluating the overall disease duration, we did not observe any significant difference between patients with (3.4±2.15 years) and without (3.4±2.89 years) autoimmune abnormalities. However, PANDAS patients with autoimmune diseases or positivity for any organ- and nonorgan-specific antibodies showed significantly higher anti-streptolysin O and anti-DNAse B

    The PanDA (Production and Distributed Analysis) workload management system (WMS) was developed to meet the scale and complexity of LHC distributed computing for the ATLAS experiment. While PanDA currently distributes jobs to more than 100,000 cores at well over 100 Grid sites, next LHC data taking run will require more resources than Grid computing can possibly provide. To alleviate these challenges, ATLAS is engaged in an ambitious program to expand the current computing model to include additional resources such as the opportunistic use of supercomputers. We will describe a project aimed at integration of PanDA WMS with Titan supercomputer at Oak Ridge Leadership Computing Facility (OLCF). Current approach utilizes modi ed PanDA pilot framework for job submission to Titan's batch queues and local data management, with light-weight MPI wrappers to run single threaded workloads in parallel on Titan's multi-core worker nodes.

    In this study, landmark-based methods of geometric morphometrics are used for investigating the main aspects of cranial shape transformation in the evolution of the giant panda, Ailuropoda melanoleuca. Specifically, we explore if the highly derived cranial adaptations for bamboo feeding of the living panda were developed early in the panda's lineage. Results obtained show that the overall cranial morphologies of the oldest known panda, the "pygmy" Ailuropoda microta, and the late Pleistocene Ailuropoda baconi are both very similar to that of their closest living relative, A. melanoleuca, which agrees with a previous proposal based on qualitative criteria. However, we also describe several differences between the crania of A. microta, A. baconi, and A. melanoleuca, including the development of the postorbital process, the orientation of the occipital region, and the expansion of the braincase. As a result, the cranial morphology of A. microta shows a less specialized morphology toward a fibrous and durophagous diet compared to the giant panda. These results are confirmed by a comparative analysis of the dimensions of the upper teeth in bears, which has revealed differences in relative tooth size between A. microta and A. melanoleuca, most probably as a result of mosaic evolution. Therefore, we conclude that cranial shape did not remain essentially uniform in the Ailuropoda lineage, as previously thought, but underwent a number of changes during more than 2 Myr.

    The phylogenetic position of the giant panda, Ailuropoda melanoleuca (Carnivora: Ursidae: Ailuropodinae), has been one of the most hotly debated topics by mammalian biologists and paleontologists during the last century. Based on molecular data, it is currently recognized as a true ursid, sister-taxon of the remaining extant bears, from which it would have diverged by the Early Miocene. However, from a paleobiogeographic and chronological perspective, the origin of the giant panda lineage has remained elusive due to the scarcity of the available Miocene fossil record. Until recently, the genus Ailurarctos from the Late Miocene of China (ca. 8-7 mya) was recognized as the oldest undoubted member of the Ailuropodinae, suggesting that the panda lineage might have originated from an Ursavus ancestor. The role of the purported ailuropodine Agriarctos, from the Miocene of Europe, in the origins of this clade has been generally dismissed due to the paucity of the available material. Here, we describe a new ailuropodine genus, Kretzoiarctos gen. nov., based on remains from two Middle Miocene (ca. 12-11 Ma) Spanish localities. A cladistic analysis of fossil and extant members of the Ursoidea confirms the inclusion of the new genus into the Ailuropodinae. Moreover, Kretzoiarctos precedes in time the previously-known, Late Miocene members of the giant panda clade from Eurasia (Agriarctos and Ailurarctos). The former can be therefore considered the oldest recorded member of the giant panda lineage, which has significant implications for understanding the origins of this clade from a paleobiogeographic viewpoint.

    Fifty-seven fecal samples were collected from giant pandas (Ailuropoda melanoleuca) in the China Conservation and Research Centre for the Giant Panda (CCRCGP) in Sichuan and examined for Cryptosporidium oocysts by Sheather's sugar flotation technique. An 18-year-old male giant panda was Cryptosporidium positive, with oocysts of an average size of 4.60×3.99 μm (n=50). The isolate was genetically analyzed using the partial 18S rRNA, 70 kDa heat shock protein (HSP70), Cryptosporidium oocyst wall protein (COWP) and actin genes. Multi-locus genetic characterization indicated that the present isolate was different from known Cryptosporidium species and genotypes. The closest relative was the Cryptosporidium bear genotype, with 11, 10, and 6 nucleotide differences in the 18S rRNA, HSP70, and actin genes, respectively. Significant differences were also observed in the COWP gene compared to Cryptosporidium mongoose genotype. The homology to the bear genotype at the 18S rRNA locus was 98.6%, which is comparable to that between Cryptosporidium parvum and Cryptosporidium hominis (99.2%), or between Cryptosporidium muris and Cryptosporidium andersoni (99.4%). Therefore, the Cryptosporidium in giant pandas in this study is considered as a new genotype: the Cryptosporidium giant panda genotype. PMID:23810821

    After a scheduled maintenance and upgrade period, the world's largest and most powerful machine - the Large Hadron Collider(LHC) - is about to enter its second run at unprecedented energies. In order to exploit the scientific potential of the machine, the experiments at the LHC face computational challenges with enormous data volumes that need to be analysed by thousand of physics users and compared to simulated data. Given diverse funding constraints, the computational resources for the LHC have been deployed in a worldwide mesh of data centres, connected to each other through Grid technologies. The PanDA (Production and Distributed Analysis) system was developed in 2005 for the ATLAS experiment on top of this heterogeneous infrastructure to seamlessly integrate the computational resources and give the users the feeling of a unique system. Since its origins, PanDA has evolved together with upcoming computing paradigms in and outside HEP, such as changes in the networking model, Cloud Computing and HPC. It is currently running steadily up to 200 thousand simultaneous cores (limited by the available resources for ATLAS), up to two million aggregated jobs per day and processes over an exabyte of data per year. The success of PanDA in ATLAS is triggering the widespread adoption and testing by other experiments. In this contribution we will give an overview of the PanDA components and focus on the new features and upcoming challenges that are relevant to the next decade of distributed computing workload management using PanDA.

    Cryptosporidium is a global epidemic parasite and one of the most important intestinal pathogens causing diarrhea in animals and humans. Despite extensive research on this parasite group, little is known about rates of Cryptosporidium infection in lesser pandas. In this study, we use molecular diagnostic tools to detect Cryptosporidium infections and identify Cryptosporidium species in the lesser panda. Using a PCR approach, we sequenced the 18S rRNA gene in fecal samples collected from 110 captive lesser pandas held throughout China (approximately one third of the captive population). We determined Cryptosporidium species via a BLAST comparison of our sequences against those of published Cryptosporidium sequences available in GenBank and subsequent phylogenetic analysis. We report that captive lesser pandas were infected with a single Cryptosporidium species, Cryptosporidium andersoni, at a prevalence of 6.36 % (7/110). The present investigation revealed the existence of C. andersoni infection in captive lesser panda and suggested that proper control measures should be taken carefully to protect the welfare of zoo workers and visitors.

    It has been established beyond doubt that giant panda genome lacks lignin-degrading related enzyme, gastrointestinal microbes may play a vital role in digestion of highly fibrous bamboo diet. However, there is not much information available about the intestinal bacteria composition in captive giant pandas with different ages. In this study, we compared the intestinal bacterial community of 12 captive giant pandas from three different age groups (subadults, adults, and geriatrics) through PCR-denaturing gradient gel electrophoresis (DGGE) and real-time PCR analysis. Results indicated that microbial diversity in the intestine of adults was significantly higher than that of the geriatrics (p  0.05). The predominant bands in DGGE patterns shared by the twelve pandas were related to Firmicutes and Proteobacteria. Additionally, in comparison to healthy individuals, antibiotic-treated animals showed partial microbial dysbiosis. Real-time PCR analyses confirmed a significantly higher abundance of the Lactobacillus in the fecal microbiota of adults (p  0.05). This study revealed that captive giant pandas with different ages showed different intestinal bacteria composition. PMID:27038949

    Until today there is a large debate about the existence of PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections) or PANS (pediatric acute onset neuropsychiatric syndrome). These children usually have dramatic, "overnight" onset of symptoms, including motor or vocal tics, obsessions, and/or compulsions. In addition to these symptoms, children may also have comorbid features of associated disorders. Herein, we report a family with an early onset of tics, with exclusively dystonic and guttural tics. All patients had a particularly strong excitement trigger. Two of the patients were shown to have signs suggestive of PANDAS and all family members were Group A beta-hemolytic Streptococcus (GABHS) carriers. The PANDAS spectrum is probably a group of disorders. We have described a PANDAS variant, in which the family seems to share common autoimmune pattern and may be viewed in the large spectrum of PANDAS. PMID:24891915

  19. CFD modeling of the test 25 of the PANDA experiment

    International Nuclear Information System (INIS)

    A large amount of steam and Hydrogen gas is expected to be released within the dry containment of a pressurized water reactor (PWR), after the hypothetical beginning of a severe accident leading to the melting of the core. The accurate modeling of gas distribution in a PWR containment concerns phenomena such as wall condensation, hydrogen accumulation, gas stratification and transport in the different compartments of the containment. The paper presents numerical assessments of CFD solvers NEPTUNE-CFD and Code-Saturne, and is focused on the analysis and the understanding of gas stratification and transport phenomena. NEPTUNE-CFD is dedicated to the simulation of incompressible and compressible multi-component/multi-phase flows, whereas Code-Saturne is dedicated to homogeneous incompressible or low Mach number compressible flows, with only one momentum equation representing the mixture of gases, liquid and particles. NEPTUNE-CFD is mainly used for nuclear engineering, whereas Code-Saturne is used either for nuclear and fossil energy engineering, and for environment (geophysical flows). The NEPTUNE-CFD code is developed within the framework of the NEPTUNE project, financially supported by CEA (Commissariat a l'energie Atomique), EDF, IRSN (Institut de Radioprotection et de Surete Nucleaire) and AREVA-NP. Both codes are validated and compared with experimental data corresponding to the test 25 of the PANDA experiment. This test concerns the distribution of mixture of gases (Helium as a simulant of hydrogen and condensing steam) in air over two vertical and cylindrical vessels, interconnected by a horizontal and cylindrical pipe. The overall dimensions of the experiment (Diameter ∼4 m, Height 8 m, Volume of the 2 vessels ∼180 m3) are not yet representative of the true scale of the reactors, but they already provide valuable information when compared to smaller scales (as experience TOSQAN∼7 m3). The computational results with Code-Saturne and NEPTUNE-CFD compare

    The giant panda, Ailuropoda melanoleuca, is a highly specialized Ursid whose diet consists almost entirely of various species of bamboo. Bamboo (Bambusoideae) is a grass subfamily whose species often exhibit a synchronous semelparity. Synchronous semelparity can create local drops in carrying capacity for the panda. We modeled the interaction of pandas and their bamboo food resources with an age structured panda population model linked to a natural history model of bamboo biomass dynamics based on literature values of bamboo biomass, and giant panda life history dynamics. This paper reports the results of our examination of the interaction between pandas and their bamboo food resource and its implications for panda conservation. In the model all panda populations were well below the carrying capacity of the habitat. The giant panda populations growth was most sensitive to changes in birth rates and removal of reproductive aged individuals. Periodic starvation that has been documented in conjunction with bamboo die-offs is probably related to the inability to move to other areas within the region where bamboo is still available. Based on the results of this model, giant panda conservation should concentrate on keeping breeding individuals in the wild, keep corridors to different bamboo species open to pandas, and to concentrate research on bamboo life history.

    2010-03-01

    Despite more than a decade of studying pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS), it is still not possible to confirm its existence and whether it is a poststreptococcal autoimmune disorder. Many controversies remain: the diagnostic criteria have not been validated, evidence of autoimmunity remains inconclusive, evidence of a genetic predisposition is weak, and streptococcal infections are common in childhood and could represent only a trigger of exacerbations of tics and obsessive-compulsive disorder. Patients who fit the PANDAS criteria appear to represent a subgroup of children with chronic tic disorder and/or obsessive-compulsive disorder who may experience symptom exacerbations after group A β-hemolytic streptococci infections; however, those infections are not the sole or even the most common antecedent of exacerbations. There is not enough evidence to support PANDAS as a unique clinical entity. PMID:21308506

This paradigm serves to allow a high job reliability and although it has clear advantages, such as making the working environment homogeneous, the approach presents security and traceability challenges. To address these challenges, gLExec can be used to let the payloads for each user be executed under a different UNIX user id that uniquely identifies the ATLAS user. This paper describes the recent improvements and evolution of the security model within the ATLAS PanDA system, including improvements in the PanDA pilot, in the PanDA server and their integration with MyProxy, a credential caching system that entitles a person or a service to act in the name of the issuer of the credential. Finally, it presents results from ATLAS user jobs running with gLExec and describes the deployment campaign within ATLAS.

    International Nuclear Information System (INIS)

    The PanDA (Production and Distributed Analysis) system has been developed to meet ATLAS production and analysis requirements for a data-driven workload management system capable of operating at LHC data processing scale. PanDA has performed well with high reliability and robustness during the two years of LHC data-taking, while being actively evolved to meet the rapidly changing requirements for analysis use cases. We will present an overview of system evolution including automatic rebrokerage and reattempt for analysis jobs, adaptation for the CernVM File System, support for the multi-cloud model through which Tier-2 sites act as members of multiple clouds, pledged resource management and preferential brokerage, and monitoring improvements. We will also describe results from the analysis of two years of PanDA usage statistics, current issues, and plans for the future.

    Endangered giant pandas (Ailuropoda melanoleuca) are bears (Family Ursidae), within the order Carnivora. They specialize on an herbivorous diet of bamboo yet retain a gastrointestinal tract typical of their carnivorous ancestry. The evolutionary constraints of their digestive tract result in a low extraction efficiency from bamboo (<40% in reported studies). The goal of this study was to determine the energy digestibility of bamboo by giant pandas used in digestibility trials and through subsequent analyses with bomb calorimetry. Seven digestibility trials were conducted (three with bamboo-only diets and four with supplemental diets). Energy digestibilities ranged from 7.5-38.9% for mixed diets and 9.2-34.0% for bamboo-only diets. The bamboo-only trials summarized here represent, to our knowledge, the first empirical data available for energy digestibility on a bamboo diet for giant pandas. PMID:20814990

    This work examines the effects of subsequent cycles of freezing-thawing on giant panda (Ailuropoda melanoleuca) sperm morphometry and function, and assesses whether density-gradient centrifugation (DGC) can increase the number of freezing-thawing cycles this sperm can withstand. A sperm sample was collected by electroejaculation from a mature giant panda and subjected to five freezing-thawing cycles. Although repeated freezing-thawing negatively affected (P 60% of the sperm cells in both treatments showed acrosome integrity even after the fifth freezing cycle. In fresh semen, the sperm head length was 4.7 μm, the head width 3.6 μm, area 14.3 μm(2) and perimeter length 14.1 μm. The present results suggest that giant panda sperm trends to be resistant to repeated freezing-thawing, even without DGC selection. PMID:26268795

    The Large Hadron Collider (LHC), operating at the international CERN Laboratory in Geneva, Switzerland, is leading Big Data driven scientific explorations. Experiments at the LHC explore the fundamental nature of matter and the basic forces that shape our universe, and were recently credited for the discovery of a Higgs boson. ATLAS, one of the largest collaborations ever assembled in the sciences, is at the forefront of research at the LHC. To address an unprecedented multi-petabyte data processing challenge, the ATLAS experiment is relying on a heterogeneous distributed computational infrastructure. The ATLAS experiment uses PanDA (Production ANd Distributed Analysis system) Workload Management System for managing the workflow for all data processing on over 150 data centers. Through PanDA, ATLAS physicists see a single computing facility that enables rapid scientific breakthroughs for the experiment, even though the data centers are physically scattered all over the world. While PanDA currently uses more t...

    The results of simulations for future measurements of electromagnetic form factors at \\PANDA (FAIR) within the PandaRoot software framework are reported. The statistical precision at which the proton form factors can be determined is estimated. The signal channel $\\bar p p \\to e^+ e^-$ is studied on the basis of two different but consistent procedures. The suppression of the main background channel, i.e. the $\\bar p p \\to \\pi^+ \\pi^-$, is studied. Furthermore, the background versus signal efficiency, statistic and systematic uncertainties on the extracted proton form factors are evaluated using to the two different procedures. The results are consistent with those of a previous simulation study using an older, simplified framework. However, a slightly better precision is achieved in the PandaRoot study in a large range of momentum transfer, assuming the nominal beam condition and detector performances.

    The first milk substitute for giant panda cubs was developed in 1988 based on limited data about giant panda breast milk and that of certain types of bear. Mixtures of other formulas have also been fed to cubs at some facilities. However, they are not of sufficient nutritional quality for promoting growth in panda cubs. Here, we report analysis of giant panda breast milk and propose new milk substitutes for cubs, which were developed based on the results of our analysis. The Chengdu Research Base of Giant Panda Breeding obtained breast milk samples from three giant pandas. Up to 30 ml of breast milk were collected from each mother by hand. Then, the milk samples were frozen and sent to Nihon University. The levels of protein, fat, carbohydrates, ash, moisture, vitamins, minerals, total amino acids, fatty acids, lactose and other carbohydrates in the milk were analyzed. The breast milk samples exhibited the following nutritional values: protein: 6.6-8.5%, fat: 6.9-16.4%, carbohydrates: 2.5-9.1%, ash: 0.9-1.0% and moisture: 67-83%. We designed two kinds of milk substitutes based on the data obtained and the nutritional requirements of dogs, cats and rodents. The nutritional composition of the milk substitutes for the first and second stages was as follows: protein: 38 and 26%, fat: 40 and 40%, carbohydrates: 13 and 25%, ash: 6 and 6% and moisture: 3 and 3%, respectively. In addition, the substitutes contained vitamins, minerals, taurine, docosahexaenoic acid, lactoferrin, nucleotides and other nutrients. PMID:26781707

    The PanDA (Production and Distributed Analysis) workload management system (WMS) was developed to meet the scale and complexity of LHC distributed computing for the ATLAS experiment. While PanDA currently distributes jobs to more than 100,000 cores at well over 100 Grid sites, the future LHC data taking runs will require more resources than Grid computing can possibly provide. To alleviate these challenges, ATLAS is engaged in an ambitious program to expand the current computing model to include additional resources such as the opportunistic use of supercomputers. We will describe a project aimed at integration of PanDA WMS with Titan supercomputer at Oak Ridge Leadership Computing Facility (OLCF). The current approach utilizes a modified PanDA pilot framework for job submission to Titan's batch queues and local data management, with light-weight MPI wrappers to run single threaded workloads in parallel on Titan's multicore worker nodes. It also gives PanDA new capability to collect, in real time, information about unused worker nodes on Titan, which allows precise definition of the size and duration of jobs submitted to Titan according to available free resources. This capability significantly reduces PanDA job wait time while improving Titan's utilization efficiency. This implementation was tested with a variety of Monte-Carlo workloads on Titan and is being tested on several other supercomputing platforms.

    Few species have been of more disputed affinities than the red or lesser panda (Ailurus fulgens), an endangered endemic Southeast Asian vegetarian member of the placental mammalian order Carnivora. This peculiar carnivoran has mostly been classified with raccoons (Procyonidae) or bears (Ursidae), grouped with the giant panda (Ailuropoda melanoleuca) in their own family, or considered a separate lineage of equivocal ancestry. Recent molecular studies have indicated a close affinity of the red panda to a clade of procyonids and mustelids (weasels, otters, martens, badgers, and allies), but have failed to unambiguously resolve the position of this species relative to mephitids (skunks and stink badgers). We examined the relationship of the red panda to other extant species of the carnivoran suborder Caniformia using a set of concatenated approximately 5.5-kb sequences from protein-coding exons of five nuclear genes. Bayesian, maximum likelihood, and parsimony phylogenetic analyses strongly supported the red panda as the closest living relative of a clade containing Procyonidae and Mustelidae to the exclusion of Mephitidae. These three families together with the red panda (which is classified here as a single extant species of a distinct family, Ailuridae) compose the superfamily Musteloidea, a clade strongly supported by all our phylogenetic analyses as sister to the monophyletic Pinnipedia (seals, sea lions, walruses). The approximately unbiased, Kishino-Hasegawa, and Templeton topology tests rejected (Pfossil evidence that extends the early adaptive radiation of the total clade of musteloids to the Eocene-Oligocene transition and also suggests Asia as a center of this radiation.

  14. Simulations of SiPM based scintillation detector for PANDA

    International Nuclear Information System (INIS)

    The Facility for Antiproton and Ion Research (FAIR) is a future project at GSI which will extend hadron physics studies up to the charm meson region using antiproton beams together with a state-of-the-art PANDA (acronym for antiProton ANnihilation at DArmstadt) detector. The physics aim, in a broader sense, is to address the fundamental problems of hadron physics and aspects of Quantum Chromo Dynamics (QCD) at low energies. The proposed work in India will consist of several parts: (i) development of a SiPM based scintillation tile hodoscope for TOF information, (ii) development of a luminosity detector (silicon strip detector), and (iii) simulation studies of these detectors design as well as physics case studies. The present paper reports the initial simulation studies that have been started at Nuclear Physics Division (NPD), BARC, on the silicon photomultiplier(SiPM) based fast scintillation detector (SciTil). The hardware development activities on this SciTil detector, that are also going on in parallel at NPD, has been reported in an another contribution to this proceedings

    The bar PANDA (antiProton ANnihilation at DArmstadt) experiment will study the strong interaction in annihilation reactions between an antiproton beam and a stationary gas jet target. The detector will comprise different sub-detectors for tracking, particle identification and calorimetry. The Micro-Vertex Detector (MVD) as the innermost part of the tracking system will allow precise tracking and detection of secondary vertices. For the readout of the double-sided silicon strip sensors a custom-made ASIC is being developed, employing the Time-over-Threshold (ToT) technique for digitization and utilize time-to-digital converters (TDC) to provide a high-precision time stamp of the hit. A custom-made Module Data Concentrator ASIC (MDC) will multiplex the data of all front-ends of one sensor towards the CERN-developed GBT chip set (GigaBit Transceiver). The MicroTCA-based MVD Multiplexer Board (MMB) at the off-detector site will receive and concentrate the data from the GBT links and transfer it to FPGA-based compute nodes for global event building.

    In this work properties of a vacuum phototriode (VPT) and preamplifier unit designed for the electromagnetic calorimeter of the PANDA experiment being built at FAIR are investigated. With the use of lead tungstate and lanthanium bromide scintillators the VPT properties are studied at low photon energies, from tens of keV in the lanthanium bromide measurements and between 10 MeV and 60 MeV in the lead tungstate measurements. At these energies the noise of the VPT unit can be expected to influence its performance significantly. It is shown that the noise contribution to the measured energy resolution, under optimal conditions, is consistent with a fluctuation of (one standard deviation) approximately 200 electrons at the VPT anode. For a lead tungstate crystal this is equivalent to a noise of 1.2 MeV. For lanthanium bromide this makes it possible to use VPTs for gamma ray spectroscopy above a few hundreds of keV without noticeable effects on the energy resolution compared to measurements with a standard photomultiplier.

  17. Fast signal analysis for the PANDA electromagnetic calorimeter

    International Nuclear Information System (INIS)

    Antiproton-proton annihilations at the future FAIR facility at Darmstadt, Germany, will allow testing the theory of strong interactions, QCD, in the non-perturbative regime. The PANDA detector will be installed in the antiproton storage ring HESR providing an intense high-resolution antiproton beam with dense internal targets. The Electromagnetic Calorimeter (EMC) is a crucial component to provide high sensitivity for studies of charm-quark mesons, glueballs and hybrid states. The EMC employs fast bright PWO scintillation crystals with Large-Area Avalanche Photo Diodes (LAAPD) as photosensors. Low-noise low-power preamplifiers were developed suitable for the expected high rates and the required large dynamic range of photon energy deposition between 1 MeV and 12 GeV. Measurements were performed on signals from cooled PWO crystals equipped with LAAPD and either discrete or ASIC preamplifiers, recorded by a fast sampling ADC. Sampling rate and ADC resolution have been determined for achieving the required energy and timing performance. The concept of the EMC front-end electronics is discussed, including a fast feature extraction algorithm. Results of recent prototype studies are presented.

    Air quality has become a pressing problem in Asia and specifically in China due to rapid economic development (i.e., rapidly expanding motor vehicle fleets, growing industrial and power generation activities, domestic and biomass burning). In spite of efforts to reduce chemical emissions, high levels of particle matter and ozone are observed and lead to severe health problems with a large number of premature deaths. To support efforts to reduce air pollution, the European Union is supporting the PANDA project whose objective is to use space and surface observations of chemical species as well as advanced meteorological and chemical models to analyze and predict air quality in China. The Project involves 7 European and 7 Chinese groups. The paper will describe the objectives of the project and present some first accomplishments. The project focuses on the improvement of methods for monitoring air quality from combined space and in-situ observations, the development of a comprehensive prediction system that makes use of these observations, the elaboration of indicators for air quality in support of policies, and the development of toolboxes for the dissemination of information.

  19. New developments for the GEM-based TPC for PANDA

    International Nuclear Information System (INIS)

    The PANDA experiment is an internal target experiment at the High Energy Storage Ring (HESR) at the new Facility for Antiproton and Ion Research (FAIR) at Darmstadt. A TPC is proposed as the central tracker due to its good position and momentum resolution, its low material budget, and its particle identification capabilities via ionization measurements. The continuous nature of the antiproton beam makes the use of a traditional ion gate impractical and hence GEM foils are used for gas amplification, due to their intrinsic ion back flow suppression properties. A small prototype of this GEM-TPC (diameter 200mm, drift length 77mm) has been built and characterized with cosmic muons using a rectangular pad readout structure. The chamber has recently been upgraded with a new readout plane with hexagonal pads, and new front end electronics, based on the AFTER ASIC. The performance of the detector is expected to improve significantly and is currently being studied at a beam test at the ELSA accelerator at Bonn. Preliminary results are presented in this talk.

    Perianal streptococcal dermatitis is an infection caused by group A streptococcus (GAS). Children with a pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections (PANDAS) phenotype may have tics or obsessive compulsive symptoms secondary to a systemic immune activation by GAS infecting perianal areas. In this retrospective case series, the authors describe three children with symptoms consistent with PANDAS and a confirmed perianal streptococcal dermatitis as the likely infectious trigger. Concomitant perianal dermatitis and new-onset obsessive-compulsive symptoms and/or tics are strong indications for perianal culture and rapid antigen detection test in young children. PMID:24763762

  1. An Investigation of Cellulose Digesting Bacteria in the Panda Gut Microbiome

    The Giant Panda (Ailuropoda melanoleuca) diet consists primarily of bamboo leaves, stems and shoots. However, the Giant Panda lacks genes for the enzymes needed to digest cellulose, the core component of bamboo. Thus, it is hypothesized that the cellulolytic digestion necessary for maintaining the Giant Panda diet is carried out by microbial symbionts in the panda gut microbiota. Fecal microbiota is used as surrogate index for gut microbiota since the Giant Panda is listed by the World Conservation Union as a Threatened Species. Two bacterial isolates with potential cellulolytic activity were isolated from Giant Panda fecal samples and cultured on selective media CMC (carboxymethyl cellulose) agar and CMC-Congo Red agar using various methods of inoculation. After incubation, clearance zones around colonies were observed and used as qualitative assays for cellulose digestion. Polymerase chain reaction amplification of the 16S rRNA gene was completed and species identification was done based on the BLAST result of 16S rRNA sequence obtained using Sanger sequencing. Once the cellulase activity is confirmed, genomic DNA of the bacteria will be extracted and used for whole genome shotgun sequencing. Illumina next generation sequencing platform will be adopted as it yields high-throughput information, providing a better understanding of cellulose digestion and the molecular genetic pathways to renewable sources of biofuels. Researchers have identified multiple cellulose-digesting microbes in the Giant Panda gut, but few have applied such bacteria in converting cellulose into glucose to create biofuel. Cellulosic ethanol, a biofuel, is produced through the fermentation of lignocellulosic biomasses. This anaerobic process is aided by cellulose-digesting enzymes. Certain microbes, such as those present in the Giant Panda gut, can produce enzymes that cleave the glycosidic bonds of cellulose (C6H10O5) into glucose molecules (C6H12O6), which can then be fermented into ethanol

  11. Fast SiPM Readout of the PANDA TOF Detector

    2016-05-01

    For the identification of low momentum charged particles and for event timing purposes a barrel Time-of-Flight (TOF) detector surrounding the interaction point is planned for the PANDA experiment at FAIR . Since the boundary conditions in terms of available radial space and radiation length are quite strict the favored layout is a hodoscope composed of several thousand small scintillating tiles (SciTils) read out by silicon photomultipliers (SiPMs). A time resolution of well below 100 ps is aimed for. With the originally proposed 30 × 30 × 5 mm3 SciTils read out by two single 3 × 3 mm2 SiPMs at the rims of the scintillator the targeted time resolution can be just reached, but with a considerable position dependence across the scintillator surface. In this paper we discuss other design options to further improve the time resolution and its homogeneity. It will be shown that wide scintillating rods (SciRods) with a size of, e.g., 50 × 30 × 5 mm3 or longer and read out at opposite sides by a chain of four serially connected SiPMs a time resolution down to 50 ps can be reached without problems. In addition, the position dependence of the time resolution is negligible. These SciRods were tested in the laboratory with electrons of a 90Sr source and under real experimental conditions in a particle beam at CERN. The measured time resolutions using fast BC418 or BC420 plastic scintillators wrapped in aluminum foil were consistently between 45 and 75 ps dependent on the SciRod design. This is a significant improvement compared to the original SciTil layout.

  12. Thoracic limb morphology of the red panda (Ailurus fulgens evidenced by osteology and radiography

    Full Text Available The red panda (Ailurus fulgens is distributed primarily in the Himalayas and southern China. It is classified as a vulnerable species by the International Union for Conservation of Nature. The aim of this study was to describe the normal osteology and radiographic anatomy of the thoracic limb of the red panda. Radiography of the right thoracic limb was performed in seven captive adult red pandas. Radiographic findings were correlated with bone specimens from three adult animals. The scapula was wide craniocaudally and presented with a large area for the origin of the teres major muscle. The square-shaped major tubercle did not extend proximal to the head of the humerus. The medial epicondyle was prominent. A supracondylar foramen was present. The radial tuberosity and sesamoid bone for the abductor digiti I longus were prominent. The accessory carpal bone was directed palmarolaterally. Metacarpal bones were widely spread. The thoracic limb morphology of the red panda evidenced by osteology and radiography indicated flexibility of the thoracic limb joints and well-developed flexor and supinator muscles, which are important in arboreal quadrupedal locomotion. Knowledge gained during this study may prove useful in identifying skeletal material or remains and diagnosing musculoskeletal diseases and injuries of the thoracic limb.

  13. The PASTA chip - A free-running readout ASIC for silicon strip sensors in PANDA

    International Nuclear Information System (INIS)

    The PANDA experiment is a multi purpose detector, investigating hadron physics in the charm quark mass regime. It is one of the main experiments at the future FAIR accelerator facility, using pp annihilations from a 1.5-15 GeV/c anti-proton beam. Because of the broad physics spectrum and the similarity of event and background signals, PANDA does not rely on a hardware-level trigger decision. The innermost of PANDA's sub-systems is the Micro Vertex Detector (MVD), consisting of silicon pixel and strip sensors. The latter will be read out by a specialized, free-running readout front-end called PANDA Strip ASIC (PASTA). It has to face a high event rate of up to 40 kHz/ch in an radiation-intense environment. To fulfill the MVD's requirements, it has to give accurate timing information to incoming events (<10 ns) and determine the collected charge with an 8-bit precision. The design has to meet cooling and placing restrictions, leading to a very low power consumption (<4 mW/ch) and limited dimensions. Therefore, a simple, time-based readout approach is chosen. In this talk, the conceptual design of the front-end is presented.

    Bears produce the most altricial neonates of any placental mammal. We hypothesized that the transition from colostrum to mature milk in bears reflects a temporal and biochemical adaptation for altricial development and immune protection. Comparison of bear milks with milks of other eutherians yielded distinctive protein profiles. Proteomic and metabolomic analysis of serial milk samples collected from six giant pandas showed a prolonged transition from colostrum to main-phase lactation over approximately 30 days. Particularly striking are the persistence or sequential appearance of adaptive and innate immune factors. The endurance of immunoglobulin G suggests an unusual duration of trans-intestinal absorption of maternal antibodies, and is potentially relevant to the underdeveloped lymphoid system of giant panda neonates. Levels of certain milk oligosaccharides known to exert anti-microbial activities and/or that are conducive to the development of neonatal gut microbiomes underwent an almost complete changeover around days 20-30 postpartum, coincident with the maturation of the protein profile. A potential metabolic marker of starvation was detected, the prominence of which may reflect the natural postpartum period of anorexia in giant panda mothers. Early lactation in giant pandas, and possibly in other ursids, appears to be adapted for the unique requirements of unusually altricial eutherian neonates. PMID:26587250

  15. Feasibility studies on time-like proton electromagnetic form factors at PANDA-FAIR

    This contribution reports on the latest status of the feasibility studies for the measurement of time-like proton electromagnetic form factors (FF's) at the PANDA experiment [1] at FAIR (Germany). Electromagnetic FF's are fundamental quantities parameterizing the electric and magnetic structure of hadrons. In the time-like region proton FF's can be accessed experimentally through the annihilation processes p ¯p → l+l- (l = e, μ), assuming that the interaction takes place through the exchange of one virtual photon. Due to the low luminosity available at colliders in the past, an individual determination of the time-like electric and magnetic proton FF's was not feasible. The statistical precision, at which the proton FF's will be determined at PANDA, is estimated for both signal processes p ¯p → l+l- (l = e, μ) using the PandaRoot software, which encompasses full detector simulation and event reconstruction. The signal identification and suppression of the main background process (p ¯p → π+π-) is studied. Different methods have been used to generate and analyze the processes of interest. The results from the different analyses show that time-like electromagnetic FF's can be measured at PANDA with unprecedented statistical accuracy.

    Ice-flow velocity is a significant parameter in dynamic models of the Antarctic ice sheet, indicating how ice is transported from the interior to the ocean and how ice mass evolves. PANDA (Prydz Bay - Amery Ice shelf - Dome A) section is the key area of Chinese expedition in the Antarctic, and many scientific studies have been conducted here. In this research, SAR images including ERS-1/2, Envisat and ALOS were applied to estimate the ice velocity of PANDA Section using DInSAR and offset-tracking methods. Compared to MEaSUREs velocity (ice velocity map of the Antarctic released by National Snow and Ice Data Center) of 450 m resolution, our result with 200 m resolution achieved similar accuracy. Ice mass of PANDA section flows into the ocean mainly through Amery Ice Shelf and Polar Record Glacier. The ice velocity at the front edge of Amery Ice shelf is almost 1500 m/a, and the ice velocity of Polar Record Glacier can reach as high as 800 m/a. At most inner area of PANDA section, ice velocity is below 40 m/a. Due to the blocking of rocks and nunataks, ice flow feature in Grove Mountains area is quite complicated, which can help to demonstrate the meteorite concentration mechanism in this area.

    For many years the PanDA Workload Management System has been the basis for distributed production and analysis for the ATLAS experiment at the LHC. Since the start of data taking PanDA usage has ramped up steadily, with up to 1M completed jobs/day in 2013. The associated monitoring data volume has been rising as well, to levels that present a new set of challenges in the areas of database scalability and monitoring system performance and efficiency. Outside of ATLAS, the PanDA system is also being used in projects like AMS, LSST and a few others. It currently undergoes a significant redesign, both of the core server components responsible for workload management, brokerage and data access, and of the monitoring part, which is critically important for efficient execution of the workflow in a way that’s transparent to the user and also provides an effective set of tools for operational support.

    The giant panda (Ailuropoda melanoleuca) is an endangered species. Interleukin-18 (IL-18) plays an important role in the innate and adaptive immune responses by inducing IFN-γ. IL-18 has been implicated in the pathogenesis of various diseases. IL-18 binding protein (IL-18BP) is an intrinsic inhibitor of IL-18 that possesses higher affinity to IL-18. In this study, we cloned and characterized IL-18BP in giant panda (AmIL-18BP) from the spleen. The amino acid sequence of giant panda IL-18BP ORF shared about 65% identities with other species. To evaluate the effects of AmIL-18BP on the immune responses, we expressed the recombinant AmIL-18BP in Escherichia coli BL21 (DE3).The fusing protein PET-AmIL-18BP was purified by nickel affinity column chromatography. The biological function of purified PET-AmIL-18BP was determined on mice splenocyte by qRT-PCR. The results showed that AmIL-18BP was functional and could significantly reduce IFN-γ production in murine splenocytes. These results will facilitate the study of protecting giant panda on etiology and immunology. PMID:27234556

    The Production and Distributed Analysis system (PanDA) has been in use in the ATLAS Experiment since 2005. It uses a sophisticated pilot system to execute submitted jobs on the worker nodes. While originally designed for ATLAS, the PanDA Pilot has recently been refactored to facilitate use outside of ATLAS. Experiments are now handled as plug-ins such that a new PanDA Pilot user only has to implement a set of prototyped methods in the plug-in classes, and provide a script that configures and runs the experiment-specific payload. We will give an overview of the Next Generation PanDA Pilot system and will present major features and recent improvements including live user payload debugging, data access via the Federated XRootD system, stage-out to alternative storage elements, support for the new ATLAS DDM system (Rucio), and an improved integration with glExec, as well as a description of the experiment-specific plug-in classes. The performance of the pilot system in processing LHC data on the OSG, LCG and Nordugrid infrastructures used by ATLAS will also be presented. We will describe plans for future development on the time scale of the next few years.

    The LHC experiments are today at the leading edge of large scale distributed data-intensive computational science. The LHC's ATLAS experiment processes data volumes which are particularly extreme, over 140 PB to date, distributed worldwide at over of 120 sites. An important element in the success of the exciting physics results from ATLAS is the highly scalable integrated workflow and dataflow management afforded by the PanDA workload management system, used for all the distributed computing needs of the experiment. The PanDA design is not experiment specific and PanDA is now being extended to support other data intensive scientific applications. PanDA was cited as an example of "a high performance, fault tolerant software for fast, scalable access to data repositories of many kinds" during the "Big Data Research and Development Initiative" announcement, a 200 million USD U.S. government investment in tools to handle huge volumes of digital data needed to spur science and engineering discoveries.

    In the present study, formalin-fixed feces, oligonucleotide fingerprinting and SRY-gene based sexing were used to construct a family net for giant pandas in the Tangjiahe Natural Reserve and to assess contemporary gene flow (migration) in this population. A total of 124 fecal samples were attributed to 37 individuals (22 females and 15 males) that were then analyzed for family relationships. Based on DNA fingerprints, the deduced family net revealed the following facts: (i) First-order relatives possessed similarities from 50% to 90%, and similarities between unrelated individuals or distant relatives were as high as 77%, indicating that the Tangjiahe pandas are characterized by high genetic similarity; (ii) 15 matings were identified and 5 ones occurred between close relatives, implying that there is potential for inbreeding to impact the pandas; (iii) four mating pairs and 5 offspring presented long distance migrations, demonstrating the intra-reserve habitat is continuous; (iv) four pairs of full sibs (also female-male dyads) dispersed short distance and all of them gave birth to highly inbred offspring, reflecting long distance migration is vital for inbreeding avoidance; (v) 17 adult individuals dispersed short or moderate distance and formed three clusters on the landscape, indicating that it is necessary to find out whether there is a negative factor impacting the pandas.

    The PANDA experiment is a multi purpose detector, investigating hadron physics in the charm quark mass regime. It is one of the main experiments at the future FAIR accelerator facility, using pp annihilations from a 1.5-15 GeV/c anti-proton beam. Because of the broad physics spectrum and the similarity of event and background signals, PANDA does not rely on a hardware-level trigger decision. The innermost of PANDA's sub-systems is the Micro Vertex Detector (MVD), consisting of silicon pixel and strip sensors. The latter will be read out by a specialized, free-running readout front-end called PANDA Strip ASIC (PASTA). It has to face a high event rate of up to 40 kHz/ch in an radiation-intense environment. To fulfill the MVD's requirements, it has to give accurate timing information to incoming events (<10 ns) and determine the collected charge with an 8-bit precision. The design has to meet cooling and placing restrictions, leading to a very low power consumption (<4 mW/ch) and limited dimensions. Therefore, a simple, time-based readout approach is chosen. In this talk, the conceptual design of the front-end is presented.

  13. Giant Panda (Ailuropoda melanoleuca Buccal Mucosa Tissue as a Source of Multipotent Progenitor Cells.

    Directory of Open Access Journals (Sweden)

    Hilary M A Prescott

    Full Text Available Since the first mammal was cloned, the idea of using this technique to help endangered species has aroused considerable interest. However, several issues limit this possibility, including the relatively low success rate at every stage of the cloning process, and the dearth of usable tissues from these rare animals. iPS cells have been produced from cells from a number of rare mammalian species and this is the method of choice for strategies to improve cloning efficiency and create new gametes by directed differentiation. Nevertheless information about other stem cell/progenitor capabilities of cells from endangered species could prove important for future conservation approaches and adds to the knowledge base about cellular material that can be extremely limited. Multipotent progenitor cells, termed skin-derived precursor (SKP cells, can be isolated directly from mammalian skin dermis, and human cheek tissue has also been shown to be a good source of SKP-like cells. Recently we showed that structures identical to SKPs termed m-SKPs could be obtained from monolayer/ two dimensional (2D skin fibroblast cultures. Here we aimed to isolate m-SKPs from cultured cells of three endangered species; giant panda (Ailuropoda melanoleuca; red panda (Ailurus fulgens; and Asiatic lion (Panthera leo persica. m-SKP-like spheres were formed from the giant panda buccal mucosa fibroblasts; whereas dermal fibroblast (DF cells cultured from abdominal skin of the other two species were unable to generate spheres. Under specific differentiation culture conditions giant panda spheres expressed neural, Schwann, adipogenic and osteogenic cell markers. Furthermore, these buccal mucosa derived spheres were shown to maintain expression of SKP markers: nestin, versican, fibronectin, and P75 and switch on expression of the stem cell marker ABCG2. These results demonstrate that giant panda cheek skin can be a useful source of m-SKP multipotent progenitors. At present lack of

  14. PanDA Pilot Submission using Condor-G: Experience and Improvements

    International Nuclear Information System (INIS)

    PanDA (Production and Distributed Analysis) is the workload management system of the ATLAS experiment, used to run managed production and user analysis jobs on the grid. As a late-binding, pilot-based system, the maintenance of a smooth and steady stream of pilot jobs to all grid sites is critical for PanDA operation. The ATLAS Computing Facility (ACF) at BNL, as the ATLAS Tier1 center in the US, operates the pilot submission systems for the US. This is done using the PanDA 'AutoPilot' scheduler component which submits pilot jobs via Condor-G, a grid job scheduling system developed at the University of Wisconsin-Madison. In this paper, we discuss the operation and performance of the Condor-G pilot submission at BNL, with emphasis on the challenges and issues encountered in the real grid production environment. With the close collaboration of Condor and PanDA teams, the scalability and stability of the overall system has been greatly improved over the last year. We review improvements made to Condor-G resulting from this collaboration, including isolation of site-based issues by running a separate Gridmanager for each remote site, introduction of the 'Nonessential' job attribute to allow Condor to optimize its behavior for the specific character of pilot jobs, better understanding and handling of the Gridmonitor process, as well as better scheduling in the PanDA pilot scheduler component. We will also cover the monitoring of the health of the system.

    /hip ratio with the occurrence of hospitalizations were evaluated in a population based sample of the city of Rio de Janeiro (1996. Residents of both sexes from 20 to 60 years, totaling 1,446 men and 1,749 women were measured and interviewed in their homes. About 5% of men and 5.8% of women reported hospitalizations. Hospitalization in the previous year excluded childbirth. For women, hospitalizations increased with the increase of Body Mass Index. Logistic regression was chosen for analysis, having hospitalization as the dependent variable and including Body Mass Index, waist/hip ratio, age, smoking and per capita income in the model. Body Mass Index and waist/hip ratio were positively associated with hospitalizations only for women (Odds Ratio = 1.06 for each unit of Body Mass Index, p=0.01. In relation to abdominal fat, an increase of 12 cm in the waist and 80 cm in hips in women resulted in an Odds Ratio of 3.5 (p = 0.01. Overweight and particularly abdominal fat distribution are important risk factors for morbidity, evaluated through hospitalizations among women.

    2016-01-01

    The Production and Distributed Analysis (PanDA) system has been developed to meet ATLAS production and analysis requirements for a data-driven workload management system capable of operating at the LHC data processing scale. The PanDA pilot is one of the major components in the PanDA system. It runs on a worker node and takes care of setting up the environment, fetching and pushing data to storage, getting jobs from the PanDA server and executing them. The original PanDA Pilot was designed over 10 years ago and has since then grown organically. Large parts of the original pilot code base are now getting old and are difficult to maintain. Incremental changes and refactoring have been pushed to the limit, and the time is now right for a fresh start, informed by a decade of experience, with the PanDA Pilot 2.0 Project. To create a testing environment for module development and automated unit and functional testing for next generation pilot tasks, a simple pilot version was developed. It resembles the basic workf...

    The female giant panda Zhangxiang (pedigree number 826) was born on August 20, 2011 in Wolong Nature Reserve, China. On November 6, 2013, Zhangxiang was transported into the acclimatization enclosure in the Liziping Nature Reserve. Before Zhangxiang left the enclosure into the wild, we conducted the first study to compare microhabitats and foraging strategies between Zhangxiang in the enclosure and giant pandas in the wild. Compared with the latter, microhabitats of Zhangxiang in the enclosure are characteristic of gentler slope, more trees, higher canopy, smaller tree DBH, and lower density of living bamboos. Diet composition and foraging behaviors significantly differed between Zhangxiang and wild giant pandas, perhaps reflecting the combined consequence of environmental conditions (e.g., bamboo species) and individual status (e.g., age, mastication ability, etc.). The difference in microhabitats and foraging strategies between Zhangxiang and wild giant pandas implied that after being released into the natural habitat in the reserve, Zhangxiang will have to adapt to the environmental conditions once again. For future reintroduction, the enclosure can be extended to the Bashania spanostachya forest in the reserve, and captive giant pandas for release can thus normally transit into the wild without human intervention during acclimatization period. For other acclimatization enclosures to be constructed in the future, ecological environment inside, including topography, forests, and bamboos as well, should as possible as can match the habitat that the giant panda to-be-reinforced populations inhabit.

    Although it belongs to the order Carnivora, the giant panda is a vegetarian with 99% of its diet being bamboo. The draft genome sequence of the giant panda shows that its umami taste receptor gene Tas1r1 is a pseudogene, prompting the proposal that the loss of the umami perception explains why the giant panda is herbivorous. To test this hypothesis, we sequenced all six exons of Tas1r1 in another individual of the giant panda and five other carnivores. We found that the open reading frame (OR...

  3. Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS): An Evolving Concept.

    Science.gov (United States)

    Macerollo, Antonella; Martino, Davide

    2013-01-01

    Pediatric autoimmune neuropsychiatric disorders associated with streptococcus infections (PANDAS) originated from the observational work of Swedo and collaborators, who formalized their definition in 1998 in a set of operational criteria. The application of these criteria, which focuses on tics and obsessive-compulsive symptoms as core symptoms, has encountered difficulties, eventually leading to a high rate of misdiagnosis. In particular, the core feature represented by the association between newly diagnosed infections and neuropsychiatric symptom relapses in youths with this diagnosis could not be demonstrated by longitudinal studies. Exploratory studies aiming to identify clinical or cognitive features that could discriminate PANDAS from other pediatric obsessive-compulsive and tic disorders present methodological limitations, and therefore are not conclusive. Other behavioral features, in addition to obsessive-compulsive symptoms and tics, have been included in pediatric acute-onset neuropsychiatric syndromes (PANS) and childhood acute neuropsychiatric syndromes (CANS), two new concepts recently proposed in order to define a much broader clinical spectrum encompassing etiologically diverse entities. Given the uncertainties on the clinical definition of PANDAS, it is not surprising that evidence in support of a post-infectious, immune-mediated pathophysiology is also insufficient. Anti-dopamine receptor antibodies might be relevant to both Sydenham's chorea (SC)-the prototypical post-streptococcal neuropsychiatric disorder-and some rare forms of encephalitis targeting the basal ganglia specifically, but studies exploring their association with children fulfilling Swedo's criteria for PANDAS have been inconclusive. Moreover, we lack evidence in favor of the efficacy of antibiotic prophylaxis or tonsillectomy in patients fulfilling Swedo's criteria for PANDAS, whereas a response to immune-mediated treatments like intravenous immunoglobulins has been documented by

  6. Lyme disease and pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS): an overview.

    Science.gov (United States)

    Rhee, Hanna; Cameron, Daniel J

    2012-01-01

    Lyme disease (LD) is a complex, multisystemic illness. As the most common vector- borne disease in the United States, LD is caused by bacterial spirochete Borrelia burgdorferi sensu stricto, with potential coinfections from agents of anaplasmosis, babesiosis, and ehrlichiosis. Persistent symptoms and clinical signs reflect multiorgan involvement with episodes of active disease and periods of remission, not sparing the coveted central nervous system. The capability of microorganisms to cause and exacerbate various neuropsychiatric pathology is also seen in pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS), a recently described disorder attributed to bacterium Streptococcus pyogenes of group A beta-hemolytic streptococcus in which neurologic tics and obsessive-compulsive disorders are sequelae of the infection. In the current overview, LD and PANDAS are juxtaposed through a review of their respective infectious etiologies, clinical presentations, mechanisms of disease development, courses of illness, and treatment options. Future directions related to immunoneuropsychiatry are also discussed. PMID:22393303

    2011-06-01

    Children with obsessive compulsive disorder or tic disorders that are associated with streptococcal infections (Group A beta-hemolytic) in the oro-pharyngeal region are given the diagnosis of pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS). Tonsillectomy has been reported to resolve the neuro-psychiatric symptoms in these children. We have a case of a 9-year-old boy who was seen in our clinic with multiple recurrent streptococcal infections of the oro-pharyngeal cavity. He also exhibited neuro-psychiatric symptoms including agitation, hyperactivity, and tics. These symptoms followed his recurrent infections. Tonsillectomy was performed and in one year follow-up the patient did not have any recurrent streptococcal infections, and his neuro-psychiatric symptoms resolved completely. Guidelines for medical and surgical management of recurrent strep infections in the face of PANDAS are reviewed. PMID:21466900

    Red pandas, Ailurus fulgens, are popular exhibit animals in zoos. It is clear from data in the global studbook that there is considerable variation in their breeding success in different zoos. Population managers have long suspected that environmental temperature plays a key role in these differences. It is generally thought that this species, which is so well adapted to life in the cold damp climate of the mid-altitude forests of the Himalayas, has a problem coping with warmer climates. However, this hypothesis has not been tested until now. Using data extracted from the global studbook, we have demonstrated that climate at the location of birth has a clear impact on the survival of infant red pandas. PMID:26849175

    2016-05-01

    Transition Distribution Amplitudes (TDA) are parametrizations of the hadronic matrix elements that occur in the perturbative Quantum Chromo Dynamics (QCD) calculations of a certain family of reactions within the framework of collinear factorization. We propose a complete feasibility study of the measurement of one of the reactions covered by the TDA models p ¯p →π0J /ψ (J /ψ →e+e-) at PANDA (AntiProton ANnihilation at DArmstadt) experiment currently under construction at the future FAIR (Facility for Antiproton and Ion Research). We show that PANDA will be ideally suited to access the relevant observables, in particular the pion-to-nucleon TDAs (πN TDAs) which are important for the understanding of the pion cloud contribution in the nucleon wave function.

    2016-01-01

    A gamma counting station based on high-purity germanium (HPGe) detector was set up for the material screening of the PandaX dark matter experiments in the China Jinping Underground Laboratory. Low background gamma rate of 2.6 counts/min within the energy range of 20 to 2700 keV is achieved due to the well-designed passive shield. The sentivities of the HPGe detetector reach mBq/kg level for isotopes like K, U, Th, and even better for Co and Cs, resulted from the low-background rate and the high relative detection efficiency of 175%. The structure and performance of the counting station are described in this article. Detailed counting results for the radioactivity in materials used by the PandaX dark-matter experiment are presented. The upgrading plan of the counting station is also discussed.

    2008-01-01

    Full Text Available Natural circulation characteristics at low pressure/low power have been studied by performing experimental investigations and numerical simulations. The PANDA large-scale facility was used to provide valuable, high quality data on natural circulation characteristics as a function of several parameters and for a wide range of operating conditions. The new experimental data allow for testing and improving the capabilities of the thermal-hydraulic computer codes to be used for treating natural circulation loops in a range with increased attention. This paper presents a synthesis of a part of the results obtained within the EU-Project NACUSP “natural circulation and stability performance of boiling water reactors.” It does so by using the experimental results produced in PANDA and by showing some examples of numerical simulations performed with the thermal-hydraulic code ATHLET.

  14. Modeling the choice to switch from fuelwood to electricity. Implications for giant panda habitat conservation

    International Nuclear Information System (INIS)

    Despite its status as a nature reserve, Wolong Nature Reserve (China) has experienced continued loss of giant panda habitat due to human activities such as fuelwood collection. Electricity, though available throughout Wolong, has not replaced fuelwood as an energy source. We used stated preference data obtained from in-person interviews to estimate a random utility model of the choice of adopting electricity for cooking and heating. Willingness to switch to electricity was explained by demographic and electricity factors (price, voltage, and outage frequency). In addition to price, non-price factors such as voltage and outage frequency significantly affect the demand. Thus, lowering electricity prices and increasing electricity quality would encourage local residents to switch from fuelwood to electricity and should be considered in the mix of policies to promote conservation of panda habitat

    2011-01-01

    For several years the PanDA Workload Management System has been the basis for distributed production and analysis for the ATLAS experiment at the LHC. Since the start of data taking PanDA usage has ramped up steadily, typically exceeding 500k completed jobs/day by June 2011. The associated monitoring data volume has been rising as well, to levels that present a new set of challenges in the areas of database scalability and monitoring system performance and efficiency. These challenges are being met with a R&D effort aimed at implementing a scalable and efficient monitoring data storage based on a noSQL solution (Cassandra). We present our motivations for using this technology, as well as data design and the techniques used for efficient indexing of the data. We also discuss the hardware requirements as they were determined by testing with actual data and realistic loads.

    A novel system of nanofluidics trapping and delivery, which is known as a tissue culture system is proposed. By using the intense optical pulse(i.e., a soliton pulse) and a system constructed by a liquid core waveguide, the optical vortices (gradient optical fields/wells) can be generated, where the trapping tools in the same way as the optical tweezers in the PANDA ring resonator can be formed. By controlling the suitable parameters, the intense optical vortices can be generated within the PANDA ring resonator, in which the nanofluidics can be trapped and moved (transported) dynamically within the Tissue culture system(a wavelength router), which can be used for tissue culture and delivery in the hydroponic plant system.

    Bears produce the most altricial neonates of any placental mammal. We hypothesized that the transition from colostrum to mature milk in bears reflects a temporal and biochemical adaptation for altricial development and immune protection. Comparison of bear milks with milks of other eutherians yielded distinctive protein profiles. Proteomic and metabolomic analysis of serial milk samples collected from six giant pandas showed a prolonged transition from colostrum to main-phase lactation over a...

  4. Profile of microRNA in Giant Panda Blood: A Resource for Immune-Related and Novel microRNAs.

    Directory of Open Access Journals (Sweden)

    Mingyu Yang

    Full Text Available The giant panda (Ailuropoda melanoleuca is one of the world's most beloved endangered mammals. Although the draft genome of this species had been assembled, little was known about the composition of its microRNAs (miRNAs or their functional profiles. Recent studies demonstrated that changes in the expression of miRNAs are associated with immunity. In this study, miRNAs were extracted from the blood of four healthy giant pandas and sequenced by Illumina next generation sequencing technology. As determined by miRNA screening, a total of 276 conserved miRNAs and 51 novel putative miRNAs candidates were detected. After differential expression analysis, we noticed that the expressions of 7 miRNAs were significantly up-regulated in young giant pandas compared with that of adults. Moreover, 2 miRNAs were up-regulated in female giant pandas and 1 in the male individuals. Target gene prediction suggested that the miRNAs of giant panda might be relevant to the expressions of 4,602 downstream genes. Subseuqently, the predicted target genes were conducted to KEGG (Kyoto Encyclopedia of Genes and Genomes pathway analysis and we found that these genes were mainly involved in host immunity, including the Ras signaling pathway, the PI3K-Akt signaling pathway, and the MAPK signaling pathway. In conclusion, our results provide the first miRNA profiles of giant panda blood, and the predicted functional analyses may open an avenue for further study of giant panda immunity.

  5. The CAD model of the PANDA Micro-Vertex-Detector in physics simulations

    International Nuclear Information System (INIS)

    The Micro-Vertex-Detector (MVD) constitutes the inner tracker of the PANDA experiment, one of the large installations at the forthcoming FAIR facility. An optimization of the overall design has been accomplished. Currently the project is making rapid progress in hardware developments towards a finalized technical solution for the detector assembly. Therefore, suited tools are necessary to validate the impact of engineering solutions on the physics performance and to introduce a more realistic description of the detector. The cross-link between engineering developments and detector simulations is important for both further optimization of the detector assembly and appropriate implementation of the MVD into the PANDA simulation framework. In this article, a full chain of the migration of a detailed CAD model including all technical and engineering input to the software framework used for detector simulations and future data analysis of the PANDA experiment is presented. First, a short introduction to the experiment and a description of the conceptual layout is given. Afterward, the detailed MVD model and introduction to the physics simulation framework are described. Finally, first results of coverage tests performed and radiation length studies are exemplarily presented in order to demonstrate the successful migration of the entire detector model.

    2015-02-01

    The versatile 4π-detector PANDA will be built at the Facility for Antiproton and Ion Research (FAIR), an accelerator complex, currently under construction near Darmstadt, Germany. A cooled antiproton beam in a momentum range of 1.5 - 15GeV/c will be provided by the High Energy Storage Ring (HESR). All measurements at PANDA rely on an excellent performance of the detector with respect to tracking, particle identification and energy measurement. The electromagnetic calorimeter (EMC) of the PANDA detector will be equipped with 15744 PbWO4 crystals (PWO-II), which will be operated at a temperature of - 25° C in order to increase the light output. The design of the forward endcap of the EMC has been finalized. The crystals will be read out with Large Area Avalanche Photo Diodes (LAAPDs) in the outer regions and with Vacuum Photo Tetrodes (VPTTs) in the innermost part. Production of photosensor units utilizing charge integrating preamplifiers has begun. A prototype comprised of 216 PbWO4 crystals has been built and tested at various accelerators (CERN SPS, ELSA/Bonn, MAMI/Mainz), where the crystals have been exposed to electron and photon beams of 25MeV up to 15GeV. The results of these test measurements regarding the energy and position resolution are presented.

  7. Proton electromagnetic form factors: present status and future perspectives at PANDA

    2015-05-01

    Data and models on electromagnetic proton form factors are reviewed, highlighting the contribution foreseen by the PANDA collaboration. Electromagnetic hadron form factors contain essential information on the internal structure of hadrons. Precise and surprising data have been obtained at electron accelerators, applying the polarization method in electron-proton elastic scattering. At electron-positron colliders, using initial state radiation, BABAR measured proton time-like form factors in a wide time-like kinematical region and the BESIII collaboration will measure very precisely proton and neutron form factors in the threshold region. In the next future an antiproton beam with momentum up to 15 GeV/c will be available at FAIR (Darmstadt). Measurements of the reaction p̅ + p → e+ + e- by the PANDA collaboration will contribute to the individual determination of electric and magnetic form factors in the time-like region of momentum transfer squared, as well as to their first determination in the unphysical region (below the kinematical threshold), through the reaction p̅ + p → e+ + e- + π0. From the discussion on feasibility studies at PANDA, we focus on the consequences of such measurements in view of an unified description of form factors in the full kinematical region. We present models which have the necessary analytical requirements and apply to the data in the whole kinematical region.

    2016-07-01

    We report on the modeling of the depolarization loss in the conventional and panda-shaped photonic crystal fiber lasers (PCFLs) due to the self-heating of the fiber, which we call it thermal stress-induced depolarization loss (TSIDL). We first calculated the temperature distribution over the fiber cross sections and then calculated the thermal stresses/strains as a function of heat load per meter. Thermal stress-induced birefringence (TSIB), which is defined as |n x - n y |, in the core and cladding regions was calculated. Finally, TSIDL was calculated for the conventional and panda-shaped PCFLs as a function of fiber length and, respectively, saturated values of 22 and 25 % were obtained which were independent of heat load per meter. For panda-shaped PCFLs, prior to being saturated, an oscillating and damping behavior against the fiber length was seen where in some lengths reached 35 %. The results are close to an experimental value of 30 % reported for a pulsed PCFL (Limpert et al., Opt Express 12:1313-1319, 2004) where the authors reported a degree of polarization of 70 % (i.e., a depolarization of 30 %). The most important result of this work is a saturation behavior of TSIDL at long-enough lengths of the fiber laser which is independent of heat load per meter. To our knowledge, this the first report of TSIBL for PCFLs.

    Highlights: ► Counterpart tests were performed on two large-scale BWR integral facilities. ► Similarity of post-LOCA system behaviors observed between two tests. ► Passive core and containment cooling systems work as design in both tests. -- Abstract: A counterpart test to the Passive Nachwärmeabfuhr und Druckabbau Test Anlage (Passive Decay Heat Removal and Depressurization Test Facility, PANDA) International Standard Problem (ISP)-42 test was conducted at the Purdue University Multi-Dimensional Integral Test Assembly (PUMA) facility. Aimed to support code validation on a range of light water reactor (LWR) containment issues, the ISP-42 test consists of six sequential phases (Phases A–F) with separately defined initial and boundary conditions, addressing different stages of anticipated accident scenario and system responses. The counterpart test was performed from Phases A to D, which are within the scope of the normal integral tests performed on the PUMA facility. A scaling methodology was developed by using the PANDA facility as prototype and PUMA facility as test model, and an engineering scaling has been applied to the PUMA facility. The counterpart test results indicated that functions of passive safety systems, such as passive containment cooling system (PCCS) start-up, gravity-driven cooling system (GDCS) discharge, PCCS normal operation and overload function were confirmed in both the PANDA and PUMA facilities with qualitative similarities.

  11. Simulation and Analysis of Multisoliton Generation Using a PANDA Ring Resonator System

    International Nuclear Information System (INIS)

    A novel system of multisoliton generation using nonlinear equations of the propagating signals is presented. This system uses a PANDA ring resonator incorporated with an add/drop filter system. Using resonant conditions, the intense optical fields known as multisolitons can be generated and propagated within a Kerr-type nonlinear medium. The present simulation results show that multisolitons can be controlled by using additional Gaussian pulses input into the add port of the PANDA system. For the soliton pulse in the microring device, a balance should be achieved between dispersion and nonlinear lengths. Chaotic output signals from the PANDA ring resonator are input into the add/drop filter system. Chaotic signals can be filtered by using the add/drop filter system, in which multi dark and bright solitons can be generated. In this work multi dark and bright solitons with an FWHM and an FSR of 425pm and 1.145 nm are generated, respectively, where the Gaussian pulse with a central wavelength of 1.55 μm and power of 600 mW is input into the system.

  12. Influence of the distribution of noncondensibles on passive containment condenser performance in PANDA

    International Nuclear Information System (INIS)

    Recently, passive cooling systems have been designed for the long-term decay heat removal from the containment of Advanced Light Water Reactors. In particular, the long-term LOCA response of the Passive Containment Cooling System (PCCS) for the General Electric European Simplified Boiling Water Reactor (ESBWR) has been tested in the large scale PANDA facility. The PANDA tests achieved the dual objective of improving confidence in the performance of the passive heat removal mechanisms underlying the design of the tested systems and extending the data base available for containment analysis code qualification. The tests conducted subject the PCCS to a variety of conditions representing design-basis and beyond-design-basis accident conditions. These include operation in the presence of both heavier and lighter than steam noncondensible gases as well as a variety of asymmetric conditions and challenging start-up conditions. The present paper addresses the transient distribution of noncondensibles and their effect on the passive condenser performance in PANDA

    International Nuclear Information System (INIS)

    The anti PANDA detector will be a located at the high energy storage ring (HESR), at the facility for anti protons and ion research (FAIR) in Darmstadt, Germany. It will operate with a very high interaction rate of up to 20 MHz, in a free streaming mode without hardware trigger. Data filtering will be performed by complete online event reconstruction with a highly parallelized farm of FPGAs as first level and on a farm of GPUs or PCs as a second level. The requirement is a background reduction by a factor of >1000. Parts of the PANDA detector will be pre-assembled and tested at the Forschungszentrum Juelich, before being transported to GSI at a later stage. The data acquisition (DAQ) system for the pre-assembly comprises of a Synchronization Of Data Acquisition (SODA) source, up to 9 Trigger and Readout Boards (TRB) based on a Lattice ECP3 FPGAs, for data concentration, and up to 4 Compute Nodes (CN), for event building and filtering. A CN is a xTCA-compliant board based on a Virtex-5 FX70T FPGA, with a μTCA-formcator. It is equipped with 2x2 GB DDR2 RAM, one GB/Ethernet and 4x6.25 Gb/s optical links. In this contribution, we present the DAQ system for the pre-assembly for anti PANDA, which will have up to 207 optical links as inputs and Gb/Ethernet as output.

    Recently passive cooling systems have been designed for the long-term decay heat removal from the containment of Advanced Light Water Reactors. In particular, the long-term LOCA response of the Passive Containment Cooling System (PCCS) for the General Electric European Simplified Boiling Water Reactor (ESBWR) has been tested in the large-scale PANDA facility. The PANDA tests achieved the dual objectives of improving confidence in the performance of the passive heat removal mechanisms underlying the design of the system, and extending the database available for containment analysis code qualification. The tests conducted subject the PCCS to a variety of conditions representing design-basis and beyond-design-basis accident conditions. These include operation in the presence of both heavier and lighter than steam non-condensable gases, as well as a variety of asymmetric and challenging start-up conditions. The present paper addresses the transient distribution of non-condensables in PANDA, and their effect on (passive) condenser performance. (author)

  16. The Forward Endcap of the Electromagnetic Calorimeter for the PANDA Detector at FAIR

    International Nuclear Information System (INIS)

    The versatile 4π-detector PANDA will be built at the Facility for Antiproton and Ion Research (FAIR), an accelerator complex, currently under construction near Darmstadt, Germany. A cooled antiproton beam in a momentum range of 1.5 – 15GeV/c will be provided by the High Energy Storage Ring (HESR). All measurements at PANDA rely on an excellent performance of the detector with respect to tracking, particle identification and energy measurement. The electromagnetic calorimeter (EMC) of the PANDA detector will be equipped with 15744 PbWO4 crystals (PWO-II), which will be operated at a temperature of – 25° C in order to increase the light output. The design of the forward endcap of the EMC has been finalized. The crystals will be read out with Large Area Avalanche Photo Diodes (LAAPDs) in the outer regions and with Vacuum Photo Tetrodes (VPTTs) in the innermost part. Production of photosensor units utilizing charge integrating preamplifiers has begun. A prototype comprised of 216 PbWO4 crystals has been built and tested at various accelerators (CERN SPS, ELSA/Bonn, MAMI/Mainz), where the crystals have been exposed to electron and photon beams of 25MeV up to 15GeV. The results of these test measurements regarding the energy and position resolution are presented

    Understanding present patterns of genetic diversity is critical in order to design effective conservation and management strategies for endangered species.Tangjiahe Nature Reserve (NR) is one of the most important national reserves for giant pandas Ailuropoda melanoleuca in China.Previous studies have shown that giant pandas in Tangjiahe NR may be threatened by population decline and fragmentation.Here we used 10 microsatellite DNA markers to assess the genetic variability in the Tangjiahe population.The results indicate a low level of genetic differentiation between the Hongshihe and Motianling subpopulations in the reserve.Assignment tests using the Bayesian clustering method in STRUCTURE identified one genetic cluster from 42 individuals of the two subpopulations.All individuals from the same subpopulation were assigned to one cluster.This indicates high gene flow between subpopulations.F statistic analyses revealed a low Fls-value of 0.024 in the total population and implies a randomly mating population in Tangjiahe NR.Additionally,our data show a high level of genetic diversity for the Tangjiahe population.Mean allele number (A),Allelic richness (AR) and mean expected heterozygosity (HE) for the Tangiiahe population was 5.9,5.173 and 0.703,respectively.This wild giant panda population can be restored through concerted effort [Current Zoology 57 (6):717-724,2011].

    2014-01-01

    Experiments at the Large Hadron Collider (LHC) face unprecedented computing challenges. Heterogeneous resources are distributed worldwide, thousands of physicists analyzing the data need remote access to hundreds of computing sites, the volume of processed data is beyond the exabyte scale, and data processing requires more than a billion hours of computing usage per year. The PanDA (Production and Distributed Analysis) system was developed to meet the scale and complexity of LHC distributed computing for the ATLAS experiment. In the process, the old batch job paradigm of computing in HEP was discarded in favor of a far more flexible and scalable model. The success of PanDA in ATLAS is leading to widespread adoption and testing by other experiments. PanDA is the first exascale workload management system in HEP, already operating at a million computing jobs per day, and processing over an exabyte of data in 2013. We will describe the design and implementation of PanDA, present data on the performance of PanDA a...

    The giant panda skeletal muscle cells, uterus epithelial cells and mammary gland cells from an adult individual were cultured and used as nucleus donor for the construction of interspecies embryos by transferring them into enucleated rabbit eggs. All the three kinds of somatic cells were able to reprogram in rabbit ooplasm and support early embryo development, of which mammary gland cells were proven to be the best, followed by uterus epithelial cells and skeletal muscle cells. The experiments showed that direct injection of mammary gland cell into enucleated rabbit ooplasm, combined with in vivo development in ligated rabbit oviduct, achieved higher blastoeyst development than in vitro culture after the somatic cell was injected into the perivitelline space and fused with the enucleated egg by electrical stimulation. The chromosome analysis demonstrated that the genetic materials in reconstructed blastocyst cells were the same as that in panda somatic cells. In addition, giant panda mitochondrial DNA (

  11. gLExec and MyProxy integration in the ATLAS/OSG PanDA workload management system

    International Nuclear Information System (INIS)

    Worker nodes on the grid exhibit great diversity, making it difficult to offer uniform processing resources. A pilot job architecture, which probes the environment on the remote worker node before pulling down a payload job, can help. Pilot jobs become smart wrappers, preparing an appropriate environment for job execution and providing logging and monitoring capabilities. PanDA (Production and Distributed Analysis), an ATLAS and OSG workload management system, follows this design. However, in the simplest (and most efficient) pilot submission approach of identical pilots carrying the same identifying grid proxy, end-user accounting by the site can only be done with application-level information (PanDA maintains its own end-user accounting), and end-user jobs run with the identity and privileges of the proxy carried by the pilots, which may be seen as a security risk. To address these issues, we have enabled PanDA to use gLExec, a tool provided by EGEE which runs payload jobs under an end-user's identity. End-user proxies are pre-staged in a credential caching service, MyProxy, and the information needed by the pilots to access them is stored in the PanDA DB. gLExec then extracts from the user's proxy the proper identity under which to run. We describe the deployment, installation, and configuration of gLExec, and how PanDA components have been augmented to use it. We describe how difficulties were overcome, and how security risks have been mitigated. Results are presented from OSG and EGEE Grid environments performing ATLAS analysis using PanDA and gLExec.

    The conventional nozzle vibration technique of the hydrogen micro-droplet generation that is supposed to be used for internal pellet target production for the future PANDA experiment at the international FAIR facility in Darmstadtfor is described. The operation of this technique has been investigated by means of detailed computer simulations. Results of calculations for the geometry and operation conditions of the WASA pellet generator are presented and discussed. We have found that for every given pellet size, there is a set of operation parameters where the efficiency of the WASA hydrogen pellet target operation is considerably increased. Moreover, the results of presented computer simulations clearly show that the future PANDA pellet target setup can be realized with the use of much smaller (and cheaper) vacuum pumps than those used at present in the WASA hydrogen pellet target. To qualitatively improve the PANDA hydrogen pellet target performance we have proposed the use of a novel flow focusing method of Ganan-Calvo and Barreto (1997,1999) combined with the use of conventional vacuum injection capillary. Possibilities of this approach for the PANDA pellet target production have been also explored by means of computer simulations. The results of these simulations show that the use of this new approach looks very promising and in particular, there is no need here to use of expensive ultra-pure hydrogen to prevent nozzle clogging or freezing up due to impurities and it will allow simple, fast, smooth and a wide range of change of pellet sizes in accordance with requirements of different experiments at the PANDA detector. In this article we also propose and describe the idea of a new technique to break up a liquid microjet into microdroplets using a process of liquid jet evaporation under pulsed laser beam irradiation. This technique should be experimentally checked before it may be used in the design of the future PANDA pellet target setup.

    The barrel time-of-flight (TOF) detector for the PANDA experiment at FAIR in Darmstadt is planned as a scintillator tile hodoscope (SciTil) using 8000 small scintillator tiles. It will provide fast event timing for a software trigger in the otherwise trigger-less data acquisition scheme of PANDA, relative timing in a multiple track event topology as well as additional particle identification in the low momentum region. The goal is to achieve a time resolution of sigma ~ 100 ps. We have conducted measurements using organic scintillators coupled to Silicon Photomultipliers (SiPM). The results are encouraging such that we are confident to reach the required time resolution.

    A novel system of multisoliton generation using nonlinear equations of the propagating signals is presented.This system uses a PANDA ring resonator incorporated with an add/drop filter system.Using resonant conditions,the intense optical fields known as multisolitons can be generated and propagated within a Kerr-type nonlinear medium.The present simulation results show that multisolitons can be controlled by using additional Gaussian pulses input into the add port of the PANDA system.For the soliton pulse in the microring device,a balance should be achieved between dispersion and nonlinear lengths.Chaotic output signals from the PANDA ring resonator are input into the add/drop filter system.Chaotic signals can be filtered by using the add/drop filter system,in which multi dark and bright solitons can be generated.In this work multi dark and bright solitons with an FWHM and an FSR of 425pm and 1.145nm are generated,respectively,where the Gaussian pulse with a central wavelength of 1.55 μm and power of 600mW is input into the system.The generation of multisolitons becomes an interesting subject when it is used to enlarge the capacity of communication channels.[1] The high optical output of the ring resonator system is of benefit to long distance communication links.[2] Two techniques can be used to generate soliton pulses.First,soliton pulses can be obtained using a ring resonator system where large amplified signals are achieved.Second,a Gaussian soliton can be generated in a simple system arrangement.[3]This application becomes an attractive tool in the area of photonics for soliton generation and investigation.%A novel system of multisoliton generation using nonlinear equations of the propagating signals is presented.

    Dietary shifts can result in changes to the gastrointestinal tract (GIT) microbiota, leading to negative outcomes for the host, including inflammation. Giant pandas (Ailuropoda melanoleuca) are physiologically classified as carnivores; however, they consume an herbivorous diet with dramatic seasonal dietary shifts and episodes of chronic GIT distress with symptoms including abdominal pain, loss of appetite and the excretion of mucous stools (mucoids). These episodes adversely affect the overall nutritional and health status of giant pandas. Here, we examined the fecal microbiota of two giant pandas’ non-mucoid and mucoid stools and compared these to samples from a previous winter season that had historically few mucoid episodes. To identify the microbiota present, we isolated and sequenced the 16S rRNA using next-generation sequencing. Mucoids occurred following a seasonal feeding switch from predominately bamboo culm (stalk) to leaves. All fecal samples displayed low diversity and were dominated by bacteria in the phyla Firmicutes and to a lesser extent, Proteobacteria. Fecal samples immediately prior to mucoid episodes had lower microbial diversity as compared to mucoids. Mucoids were mostly comprised of common mucosal-associated taxa including Streptococcus and Leuconostoc species, and exhibited increased abundance for bacteria in the family Pasteurellaceae. Taken together, these findings indicate that mucoids may represent an expulsion of the mucosal lining that is driven by changes in diet. We suggest that these occurrences serve to reset their GIT microbiota following changes in bamboo part preference, as giant pandas have retained a carnivorous GIT anatomy while shifting to an herbivorous diet.

    Air pollution has become a pressing problem in Asia and specifically in China due to rapid increase in anthropogenic emissions related to growth of China's economic activity and increasing demand for energy in the past decade. Observed levels of particulate matter and ozone regularly exceed World Health Organization (WHO) air quality guidelines in many parts of the country leading to increased risk of respiratory illnesses and other health problems. The EU-funded project PANDA aims to establish a team of European and Chinese scientists to monitor air pollution over China and elaborate air quality indicators in support of European and Chinese policies. PANDA combines state-of-the-art air pollution modeling with space and surface observations of chemical species to improve methods for monitoring air quality. The modeling system of the PANDA project follows a downscaling approach: global models such as MOZART and MACC system provide initial and boundary conditions to regional WRF-Chem and EMEP simulations over East Asia. WRF-Chem simulations at higher resolution (e.g. 20km) are then performed over a smaller domain covering East China and initial and boundary conditions from this run are used to perform simulations at a finer resolution (e.g. 5km) over specific megacities like Shanghai. Here we present results of model simulations for January and July 2010 performed during the first year of the project. We show an intercomparison of the global (MACC, EMEP) and regional (WRF-Chem) simulations and a comprehensive evaluation with satellite measurements (NO2, CO) and in-situ data (O3, CO, NOx, PM10 and PM2.5) at several surface stations. Using the WRF-Chem model, we demonstrate that model performance is influenced not only by the resolution (e.g. 60km, 20km) but also the emission inventories used (MACCity, HTAPv2), their resolution and diurnal variation, and the choice of initial and boundary conditions (e.g. MOZART, MACC analysis).

    PANDA, an experiment at the upcoming FAIR facility in Germany, aims at hadron spectroscopy with high precision and rate by exploiting gluon-rich proton-antiproton collisions at momenta from 1.5 GeV/c to 15 GeV/c. Almost 4π coverage by all detector components is a prerequisite to realize this goal. The objective of this thesis is the system design of a novel type of DIRC Cherenkov detector for particle identification at the forward endcap of the PANDA target spectrometer. A key feature of this detector is its compact, planar design which occupies less than 5 cm in beam direction at the acceptance region (θ<22 ) and ∝20 cm at the outer rim where single-photon imaging cameras are located. After the definition of system requirements, the system has been dissected into individual logical components. For each component, possible hardware and design options have been identified, analyzed and evaluated for compliance with the requirements and their impact on the system performance. The optical system and sensor layout have been optimized to compromise complexity and performance, leading to a highly modular detector setup. The resulting definition of the design comprises the specification of the optical setup, the photosensor and the front-end electronics. Further, a concept for the implementation of the pattern reconstruction algorithm for online reconstruction has been proposed. The novel concept also required the development of dedicated particle identification algorithms which permit the efficient analysis of the measured time-correlated photon patterns. These algorithms have been tested with signals generated by means of time-based Monte Carlo simulations which resemble the time characteristics of the quasi-continuous interaction at the highest rate expected at PANDA. The resulting performance estimations predict a π/K-separation up to 4σ at 4 GeV/c.

    The paper presents numerical analysis compared with experimental data of influence of polymerization shrinkage on highly birefringent (HB) PANDA optical fibers embedded in a composite material. Since polymerization is a chemical process consisting in combining single molecules in a macromolecular compound [1], principal directions of the polymerization shrinkage depend on a number of the composite layers associated with this process. In this paper a detailed analysis of the piezo-optic effects occurring in HB optical fibers before and after the lamination process answers the question to what extent a degree of the material degradation can be properly estimated.

    Regeneration of fibre Bragg gratings under application of a high temperature annealing process in a high birefringent polarisation maintaining fibre of type Panda was investigated. During the annealing process, a distinct nonlinearity and hysteresis of the birefringence with temperature was observed. After the temperature process, the birefringence between slow and fast axis at room temperature was nearly doubled, which is in agreement with observations of other researchers. The hysteresis in birefringence might be explained by the crossing of the transition temperature of the stress applying parts and the relief of in-frozen mechanical and thermal stresses.

    International Nuclear Information System (INIS)

    The Micro Vertex Detector (MVD) for the PANDA experiment is designed and optimized to reconstruct the D mesons secondary vertices and to provide the maximum acceptance close to the interaction point. The experimental physics goals and setup require sophisticated solutions for the detector integration in order to minimise the material budget. The thermal power produced by the 'on board' read-out electronics is fast removed using carbon foam as heat sink. Two types of carbon foam are under evaluation. The mechanical and thermal property behaviors after neutron irradiation test with neutrons have been studied. Results from finite element thermal analyses and test bench are also presented.

  13. Feasibility study: proton time-like electromagnetic form factors with the PANDA experiment

    International Nuclear Information System (INIS)

    Perspectives of measuring the proton electromagnetic form factors in the time-like region at FAIR with the PANDA detector are presented. A number of simulations with PANDAroot framework on the signal anti pp → e+e- efficieny as well as for the most important background anti pp → π+π- have been performed. All three hypotheses for the GE/GM = 0,1,3 have been taken into account for signal simulation. A set of cuts were implemented into analysis procedure signal and background separation. Preliminary results of statistical error analysis are shown.

  14. Experimental access to Transition Distribution Amplitudes with the PANDA experiment at FAIR

    International Nuclear Information System (INIS)

    Baryon-to-meson Transition Distribution Amplitudes (TDAs) encoding valuable new information on hadron structure appear as building blocks in the collinear factorized description for several types of hard exclusive reactions. In this paper, we address the possibility of accessing nucleon-to-pion (πN) TDAs from anti pp → e+e-π0 reaction with the future PANDA detector at the FAIR facility. At high center-of-mass energy and high invariant mass squared of the lepton pair q2, the amplitude of the signal channel anti pp → e+e-π0 admits a QCD factorized description in terms of πN TDAs and nucleon Distribution Amplitudes (DAs) in the forward and backward kinematic regimes. Assuming the validity of this factorized description, we perform feasibility studies for measuring anti pp → e+e-π0 with the PANDA detector. Detailed simulations on signal reconstruction efficiency as well as on rejection of the most severe background channel, i.e. anti pp → π+π-π0 were performed for the center-of-mass energy squared s = 5 GeV2 and s = 10 GeV2, in the kinematic regions 3.0 < q2 < 4.3 GeV2 and 5 < q2 GeV2, respectively, with a neutral pion scattered in the forward or backward cone vertical stroke cos θπ0 vertical stroke > 0.5 in the proton-antiproton center-of-mass frame. Results of the simulation show that the particle identification capabilities of the PANDA detector will allow to achieve a background rejection factor of 5 . 107 (1 . 107) at low (high) q2 for s = 5 GeV2, and of 1 . 108 (6 . 106) at low (high) q2 for s = 10 GeV2, while keeping the signal reconstruction efficiency at around 40%. At both energies, a clean lepton signal can be reconstructed with the expected statistics corresponding to 2 fb-1 of integrated luminosity. The cross sections obtained from the simulations are used to show that a test of QCD collinear factorization can be done at the lowest order by measuring scaling laws and angular distributions.

  15. Design of a test station for silicon strip sensors for PANDA

    International Nuclear Information System (INIS)

    At PANDA, which is being planned at the international accelerator facility FAIR in Darmstadt, silicon strip sensors will play an important role for the micro vertex detector (MVD). The design of the micro-strip sensor modules is a process of hardware and software development, which is combined with simulation studies to compare the results. Therefore a test station was set up and first module prototypes have been constructed and tested. Data from sensor modules with single and double sided readout are available to make first hit recognition and tracking analysis. Database structures have been developed to collect sensor and frontend characteristics for assembled sensor modules.

As investigações conduzidas pela psicologia cognitiva têm investido esforços no exame da coerência a partir da perspectiva daqueles que recebem o texto. Este estudo examinou se o estabelecimento da coerência textual está relacionado à aquisição da leitura e da escrita com jovens e adultos, em processo de alfabetização, em uma situação de produção de texto. Alunos entre 15 a 45 anos, matriculados no 1º e 2º ciclos da Educação Básica de Jovens e Adultos de uma escola pública, foram individualmente solicitados a produzir oralmente uma história original. As histórias foram analisadas em função de indicadores específicos, agrupados em um sistema de análise, o qual expressa níveis distintos acerca do estabelecimento da coerência. Comparações entre os ciclos foram realizadas. Os resultados obtidos corroboram estudo realizado com crianças. Há indicadores mais fáceis de serem estabelecidos do que outros. Pode-se argumentar que a escolaridade contribui para o estabelecimento da coerência na produção de história.

MÉTODOS: Foram utilizados dados provenientes de levantamentos epidemiológicos realizados pelo Ministério da Saúde nos anos de 1986, 2003 e 2010. A experiência de cárie, expressa pelo índice CPOD (dentes permanentes cariados, perdidos e obturados, e a saúde dentária, expressa pelo índice OH-D (dentes hígidos + obturados relativo ao número de dentes funcionais, foram comparadas em amostras aleatórias de residentes de 35 a 44 anos de idade em cada região brasileira. As diferenças nas condições dentárias entre os anos foram estimadas por meio da razão dos valores dos índices, empregando-se análise de regressão de Poisson ajustada pela idade. RESULTADOS: Houve reduções no índice CPOD e aumento no índice OH-D em todas as regiões no período de 1986 a 2010. A região Norte, que tinha o pior padrão em 1986, apresentou o maior ganho em termos de dentição funcional. CONCLUSÕES: Tem ocorrido uma transição da saúde bucal para melhor nos adultos brasileiros. É plausível que a adição de flúor à água e ao creme dental, maior incorporação de serviços restauradores e a melhoria nos indicadores de desenvolvimento humano decorrentes de políticas públicas estejam relacionados a essa melhora.

    Red pandas ( Ailurus fulgens ) are managed as captive populations in both North America and Europe. Regular review of pathology reports is a useful tool for developing veterinary care and husbandry strategies for such populations. Though thorough pathology reviews have been conducted for the European studbook, the North American population has not been reviewed similarly until now. Complete gross and histopathology reports were requested from institutions holding red pandas that died during 1992 through 2012 (n = 530), and reports were received for 95.8% of the individuals, including full necropsy records for 366 red pandas. These reports were classified by subspecies, gender, and age, then reviewed for primary cause of death and secondary pathological findings. A substantial portion of the deaths (40.2%) were neonates (animals, pneumonia was the most common cause of death. In adult (age = 366 days-10 yr) and geriatric red pandas (age >10 yr), cardiovascular disease was the most common cause of death. Renal disease and gastrointestinal disease also were common pathologic findings in adult and geriatric animals. These findings suggest that stress associated with captivity and husbandry practices, including those associated with social, environmental, and nutritional conditions, may contribute to immune and cardiovascular pathologies, and other common necropsy findings.

    Ecotourism is widely promoted as a conservation tool and actively practiced in protected areas worldwide. Theoretically, support for conservation from the various types of stakeholder inside and outside protected areas is maximized if stakeholders benefit proportionally to the opportunity costs they bear. The disproportional benefit distribution among stakeholders can erode their support for or lead to the failure of ecotourism and conservation. Using Wolong Nature Reserve for Giant Pandas (China) as an example, we demonstrate two types of uneven distribution of economic benefits among four major groups of stakeholders. First, a significant inequality exists between the local rural residents and the other types of stakeholder. The rural residents are the primary bearers of the cost of conservation, but the majority of economic benefits (investment, employment, and goods) in three key ecotourism sectors (infrastructural construction, hotels/restaurants, and souvenir sales) go to other stakeholders. Second, results show that the distribution of economic benefits is unequal among the rural residents inside the reserve. Most rural households that benefit from ecotourism are located near the main road and potentially have less impact on panda habitat than households far from the road and closer to panda habitats. This distribution gap is likely to discourage conservation support from the latter households, whose activities are the main forces degrading panda habitats. We suggest that the unequal distribution of the benefits from ecotourism can be lessened by enhancing local participation, increasing the use of local goods, and encouraging relocation of rural households closer to ecotourism facilities.

    The red panda (Ailurus fulgens fulgens) is classified as endangered due to its declining population, habitat fragmentation and poaching. Efforts are being made to breed them in captivity as part of nationwide conservation breeding program. This study aimed to standardize Enzyme immunoassays (EIAs) to monitor reproductive (Progesterone metabolite, Testosterone) and stress hormone (Cortisol) in red panda. For this purpose, we collected 1471 faecal samples from four females and one male over a period of one year from Padmaja Naidu Himalayan Zoological Park, Darjeeling, India. HPLC confirmed the presence of immunoreactive 5α-pregnan-3α-ol-20-one, testosterone and cortisol metabolites in faecal samples. Using 5α-pregnan-3α-ol-20-one EIA, we were able to monitor reproduction and detect pregnancy in one of the females, which successfully conceived and delivered during the study period. We were also able to monitor testosterone and cortisol in faecal samples of the red panda. Faecal testosterone levels were found in higher concentration in breeding season than in non-breeding season. Faecal cortisol concentrations showed a negative relationship with ambient temperature and peaked during winter months in all animals. Standardization of EIAs and faecal hormone monitoring would facilitate red panda conservation breeding programs in India and elsewhere. PMID:27481551

    Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS) is a relatively new diagnostic construct applied to children or adolescents who develop, and have repeated exacerbations of, tic disorders and/or obsessive-compulsive disorder following group A beta-hemolytic streptococcal infections. The proposed pathophysiology is that the group A beta-hemolytic streptococcal bacteria trigger antibodies that cross-react with the basal ganglia of genetically susceptible hosts leading to obsessive-compulsive disorder and/or tics. This is similar to the etiologic mechanisms proposed for Sydenham's chorea, in which group A beta-hemolytic streptococcal antibodies cross-react with the basal ganglia and result in abnormal behavior and involuntary movements. When first proposed, there was much controversy about the idea that streptococcal infections were etiologically related to rheumatic fever. In a like manner, discussion has arisen about the concept of infection-triggered obsessive-compulsive disorder and tic disorders. We review the historical background to these controversies, give an update on the findings provided by research on PANDAS, and address areas of future study. PMID:9733286

    Transcriptome analysis of polar bears (Ursus maritimus) yielded sequences with highest similarity to the human endogenous retrovirus group HERV-K(HML-2). Further analysis of the polar bear draft genome identified an endogenous betaretrovirus group comprising 26 proviral copies and 231 solo LTRs. Molecular dating indicates the group originated before the divergence of bears from a common ancestor but is not present in all carnivores. Closely related sequences were identified in the giant panda (Ailuropoda melanoleuca) and characterized from its genome. We have designated the polar bear and giant panda sequences U. maritimus endogenous retrovirus (UmaERV) and A. melanoleuca endogenous retrovirus (AmeERV), respectively. Phylogenetic analysis demonstrated that the bear virus group is nested within the HERV-K supergroup among bovine and bat endogenous retroviruses suggesting a complex evolutionary history within the HERV-K group. All individual remnants of proviral sequences contain numerous frameshifts and stop codons and thus, the virus is likely non-infectious. PMID:23725819

  10. Development of noSQL data storage for the ATLAS PanDA Monitoring System

    International Nuclear Information System (INIS)

    For several years the PanDA Workload Management System has been the basis for distributed production and analysis for the ATLAS experiment at the LHC. Since the start of data taking PanDA usage has ramped up steadily, typically exceeding 500k completed jobs/day by June 2011. The associated monitoring data volume has been rising as well, to levels that present a new set of challenges in the areas of database scalability and monitoring system performance and efficiency. These challenges are being met with an R and D effort aimed at implementing a scalable and efficient monitoring data storage based on a noSQL solution (Cassandra). We present our motivations for using this technology, as well as data design and the techniques used for efficient indexing of the data. We also discuss the hardware requirements as they were determined by testing with actual data and realistic rate of queries. In conclusion, we present our experience with operating a Cassandra cluster over an extended period of time and with data load adequate for planned application.

    Gamma spectroscopy of double Λ hypernuclei will be one of the main topics addressed by the PANDA experiment at the planned FAIR-facility at Darmstadt, Germany. For this project a dedicated hypernuclear detector setup will be installed. In addition to the general purpose of the PANDA detector it consists of a primary nuclear target for the production of Ξ- + anti Ξ pairs, a secondary active target for the formation of hypernuclei and the identification of associated decay products as well as a germanium detector array to perform γ spectroscopy. Results of the current hardware development will be presented in the talk: For the positioning of the primary filament target in the beam halo the functionality of piezo motors is investigated in vacuum. Stability tests of the primary target chamber are performed with various thin materials. For the secondary target the readout of silicon microstrip detectors with ultra-thin flexible cables is checked to fan out the readout electronics. Furthermore, design studies of support structures for the whole detector setup are considered. On the simulation side a compromise between the stopping probability of Ξ- hyperons and the reconstruction accuracy of weak decay pions is discussed.

    The two-phase xenon detector is at the frontier of dark matter direct search. This kind of detector uses liquid xenon as the sensitive target and is operated in two-phase (liquid/gas) mode, where the liquid level needs to be monitored and controlled in sub-millimeter precision. In this paper, we present a detailed design and study of two kinds of level meters for the PandaX dark matter detector. The long level meter is used to monitor the overall liquid level while short level meters are used to monitor the inclination of the detector. These level meters are cylindrical capacitors custom-made from two concentric metal tubes. Their capacitance values are read out by a universal transducer interface chip and recorded by the PandaX slow control system. We present the developments that lead to level meters with long-term stability and sub-millimeter precision. Fluctuations (standard deviations) of less than 0.02 mm for the short level meters and less than 0.2 mm for the long level meter were achieved during a few...

    The PanDA Workload Management System is the basis for distributed production and analysis for the ATLAS experiment at the LHC. In this role, it relies on sophisticated dynamic data movement facilities developed in ATLAS. In certain scenarios, such as small research teams in ATLAS Tier-3 sites and non-ATLAS Virtual Organizations, the overhead of installation and operation of these components makes their use not very cost effective. Globus Online is an emerging new tool from the Globus Alliance, which already proved popular within the research community. It provides the users with fast and robust file transfer capabilities that can also be managed from a Web interface, and in addition to grid sites, can have individual workstations and laptops serving as data transmission endpoints. We will describe the integration of the Globus Online functionality into the PanDA suite of software, in order to give more flexibility in choosing the method of data transfer to ATLAS Tier-3 and OSG users.

    As part of the ASIAEX experiment, the Acoustic Research Laboratory in the Tropical Marine Science Institute at the National University of Singapore deployed a Pop-up Ambient Noise Data Acquisition (PANDA) system. The PANDA was recovered 18 days later with over 9 days of continuous data recorded from a single hydrophone at 2 kSa/s. The data show the various sources that were deployed as part of the experiment, but also provide interesting statistical information on low-frequency ambient noise in the region and the passage of numerous ships. This deployment was in a heavy shipping traffic area, hostile both in terms of potential snagging by fishing activity and in terms of the high levels of noise encountered, both of which are of interest for the deployment and successful use of autonomous acoustic systems in busy littoral waters. We present some statistical results from the 3+ GByte of data. [Work supported by the Defence Science and Technology Agency, Singapore and the US ONR.

    We report the discovery of 59 globular clusters (GCs) and two candidate GCs in a search of the halo of M31, primarily via visual inspection of CHFT/MegaCam imagery from the Pan-Andromeda Archaeological Survey (PAndAS). The superior quality of these data also allow us to check the classification of remote objects in the Revised Bologna Catalogue (RBC), plus a subset of GC candidates drawn from SDSS imaging. We identify three additional new GCs from the RBC, and confirm the GC nature of 11 SDSS objects (8 of which appear independently in our remote halo catalogue); the remaining 188 candidates across both lists are either foreground stars or background galaxies. Our new catalogue represents the first uniform census of GCs across the M31 halo - we find clusters to the limit of the PAndAS survey area at projected radii of up to R_proj ~ 150 kpc. Tests using artificial clusters reveal that detection incompleteness cuts in at luminosities below M_V = -6.0; our 50% completeness limit is M_V ~ -4.1. We construct a un...

    We address the possibility of accessing nucleon-to-pion ($\\pi N$) Transition Distribution Amplitudes (TDAs) from $\\bar{p}p \\to e^+e^- \\pi^0$ reaction with the future \\={P}ANDA detector at the FAIR facility. At high center of mass energy and high invariant mass of the lepton pair $q^2$, the amplitude of the signal channel $\\bar{p}p \\to e^+e^- \\pi^0$ admits a QCD factorized description in terms of $\\pi N$ TDAs and nucleon Distribution Amplitudes (DAs) in the forward and backward kinematic regimes. Assuming the validity of this factorized description, we perform feasibility studies for measuring $\\bar{p}p \\to e^+e^- \\pi^0$ with the \\={P}ANDA detector. Detailed simulations on signal reconstruction efficiency as well as on rejection of the most severe background channel, {\\it i.e.} $\\bar{p}p \\to \\pi^+\\pi^- \\pi^0$ were performed for the center of mass energy squared $s = 5$ GeV$^2$ and $s = 10$ GeV$^2$, in the kinematic regions $3.0 0.5 $ in the proton-antiproton center of mass frame.

    2012-01-01

    For several years the PanDA Workload Management System has been the basis for distributed production and analysis for the ATLAS experiment at the LHC. Since the start of data taking PanDA usage has ramped up steadily, typically exceeding 500k completed jobs/day by June 2011. The associated monitoring data volume has been rising as well, to levels that present a new set of challenges in the areas of database scalability and monitoring system performance and efficiency. These challenges are being met with an R&D effort aimed at implementing a scalable and efficient monitoring data storage based on a noSQL solution (Cassandra). We present our motivations for using this technology, as well as data design and the techniques used for efficient indexing of the data. We also discuss the hardware requirements as they were determined by testing with actual data and realistic rate of queries. In conclusion, we present our experience with operating a Cassandra cluster over an extended period of time and with data loa...

  20. Design, construction and test of a precursor prototype TPC for PANDA

    International Nuclear Information System (INIS)

    A time projection chamber (TPC) is a very promising option for the central tracker of the PANDA experiment at the new Facility for Antiproton and Ion Research (FAIR) at Darmstadt, Germany. Installed in a ring-type experiment with 2.107 p anti p annihilations per second it has to be operated continuously despite the presence of space charge effects. These are kept at a bearable level using GEM-based amplification providing an intrinsic suppression of ion backflow. The system promises high-accuracy tracking as well as information on the specific energy-loss and features high momentum resolution of 1% as well as particle-identification capability with a highly homogeneous and low material budget. As a precursor prototype of a PANDA TPC a large-volume detector with a ring-cylindrical shape of the drift volume of 73 cm length and active diameters of 10/30 cm has been set up. Three GEM foils serve as an amplification stage. The signals of approximately 10.000 hexagonal pads are read out using 42 front end cards. In this contribution, we present the design and construction of the detector system and we report on the results of its commissioning.

  1. Control and management unit for a computation platform at the PANDA experiment

    International Nuclear Information System (INIS)

    The FAIR facility will provide high intensity antiproton and heavy ion beams for the PANDA and HADES experiments, leading to very high reaction rates. PANDA is expected to run at 10-20 MHz with a raw data output rate of up to 200 GB/s. A sophisticated data acquisition system is needed in order to select physically relevant events online. For this purpose a network of interconnected compute nodes can be used. Each compute node can be programmed to run various algorithms, such as online particle track recognition for high level triggering. An ATCA communication shelf provides power, cooling and high-speed interconnections to up to 14 nodes. A single shelf manager supervises and regulates the power distribution and temperature inside the shelf. The shelf manager relies on a local control chip on each node to relay sensor read-outs, provide hardware adresses and power requirements etc. An IPM controller based on an Atmel microcontroller was designed for this purpose, and a prototype was produced. The neccessary software is being developed to allow local communication with the components of the compute node and remote communication with the shelf manager conform to the ATCA specification.

    The availability of a high-intensity antiproton beam with momentum up to 15 GeV/c at the future Facility for Antiproton and Ion Research (FAIR) will open a unique opportunity to investigate wide areas of nuclear physics with the PANDA (antiProton ANnihilations at DArmstadt) detector. Part of these investigations concern the Electromagnetic Form Factors of the proton in the time-like region and the study of the transition distribution amplitudes, for which feasibility studies have been performed in this thesis. Moreover, simulations to study the efficiency and the energy resolution of the backward endcap of the electromagnetic calorimeter of PANDA are presented. This detector is crucial especially for the reconstruction of processes like anti pp{yields}e{sup +}e{sup -}{pi}{sup 0}, investigated in this work. Different arrangements of dead material were studied. The results show that both, the efficiency and the energy resolution of the backward endcap of the electromagnetic calorimeter fulfill the requirements for the detection of backward particles, and that this detector is necessary for the reconstruction of the channels of interest. The study of the annihilation channel anti pp{yields}e{sup +}e{sup -} will improve the knowledge of the electromagnetic form factors in the time-like region, and will help to understand their connection with the electromagnetic form factors in the space-like region. In this thesis the feasibility of a measurement of the anti pp{yields}e{sup +}e{sup -} cross section with PANDA is studied using Monte-Carlo simulations. The major background channel anti pp{yields}{pi}{sup +}{pi}{sup -} is taken into account. The results show a 10{sup 9} background suppression factor, which assure a sufficiently clean signal with less than 0.1 % background contamination. The signal can be measured with an efficiency greater than 30 % up to s=14 (GeV/c){sup 2}. The Electromagnetic Form Factors are extracted from the reconstructed signal and corrected

    濒危的大熊猫(Ailuropoda melanoleuca)是中国四川、甘肃和陕西省山区所特有的物种。该种在20世纪70年代有2000多只。由于生境缩小、偷猎和竹林开花等原因所致,到20世纪90年代,大熊猫种群的数量下降到不足1000只,且分离成32个亚种群。在过去的30多年中,大量竹林开花和开花后死亡是大熊猫种群数量下降的主要原因。70年代,整个岷山的大熊猫遭受饥荒,80年代蔓延到琼莱山,造成大熊猫大量死亡。大熊猫的生境被分离成很多小的"岛",每个小的生存地只有几只熊猫,使得大熊猫的生存形式进一步恶化。小的、孤立的大熊猫种群变的更加脆弱,很容易受到生境退化、自然灾害、疾病和近亲繁殖的威胁,从而导致灭绝。因此,对于保护野生大熊猫来说,恢复大熊猫的生境并把大熊猫重新引回到它们的历史生境中去,是一个重要的研究课题。%The endangered giant panda (Ailuropoda melanoleuca) is endemic to the mountains of Sichuan, Gansu and Shaanxi Provinces in China. The species had numbered over 2000 animals in early 1970s, but declined to no more than 1,000 animals fragmented into perhaps 32 subpopulations in late 1990s as the result of numerous detrimental forces such as habitat shrinking, poaching and bamboo flowering. The mass flowering and followed die-off of bamboo played key roles in the declination of panda population in the past three decades. It trigged the starvation and following high mortality of giant pandas in 1970s over Min Mountains and in 1980s across Qionglai Mountains in Sichuan Province. The situation of survivorship is made worse by the fact that the panda habitat is fragmented into many small "islands", each containing only a few pandas. Such small, isolated panda populations are rendered even more vulnerable to extinction form threats such as habitat degradation, natural disaster, disease, and the deleterious

  11. Design optimization of the PANDA micro-vertex-detector for high performance spectroscopy in the charm quark sector

    International Nuclear Information System (INIS)

    The PANDA experiment is one of the key projects at the future FAIR facility, which is currently under construction at GSI Darmstadt. Measurements will be performed with antiprotons using a fixed-target setup. The main scope of PANDA is the study of the strong interaction in the charm quark sector. Therefore, high precision spectroscopy of hadronic systems in this energy domain is a prerequisite. The Micro-Vertex-Detector (MVD) as innermost part of the tracking system plays an important role to achieve this goal. At present, the PANDA project has exceeded the initial phase of conceptual design studies. Based on these results, an optimization of the individual detector subsystems, and thus also for the MVD, is necessary to continue the overall detector development towards its commissioning. Therefore, a comprehensive and realistic detector model must be developed, which on the one hand fulfils the physics requirements but on the other hand also includes feasible engineering solutions. This task is the main scope of the present work. The outcome of these studies will deliver important contributions to the technical design report for the PANDA MVD, which is the next step towards the final detector assembly. In the first part of this work, main physics aspects of the charm spectroscopy are highlighted and a complete review of the experimental status in this field is given. Afterwards, all relevant details of the PANDA experiment are summarized. The conceptual design and associated hardware developments for the MVD are discussed separately in the following chapters. They deliver basic input for the performed detector optimization, which is presented in the central part. Furthermore, this section describes the development of a comprehensive detector model for the MVD and its introduction into the physics simulation framework of PANDA.

    We report the WIMP dark matter search results using the first physics-run data of the PandaX-II 500 kg liquid xenon dual-phase time-projection chamber, operating at the China JinPing Underground Laboratory. No dark matter candidate is identified above background. In combination with the data set during the commissioning run, with a total exposure of 3.3$\\times10^4$ kg-day,the most stringent limit to the spin-independent interaction between the ordinary and WIMP dark matter is set for a range of dark matter mass between 3.5 and 1000 GeV/c$^2$. The best upper limit on the scattering cross section is found $2.5\\times 10^{-46}$ cm$^2$ for the WIMP mass 40 GeV/c$^2$ at 90% confidence level.

    Baryon-to-meson Transition Distribution Amplitudes (TDAs) encoding valuable new information on hadron structure appear as building blocks in the collinear factorized description for several types of hard exclusive reactions. In this paper, we address the possibility of accessing nucleon-to-pion (πN) TDAs from anti pp → e{sup +}e{sup -}π{sup 0} reaction with the future PANDA detector at the FAIR facility. At high center-of-mass energy and high invariant mass squared of the lepton pair q{sup 2}, the amplitude of the signal channel anti pp → e{sup +}e{sup -}π{sup 0} admits a QCD factorized description in terms of πN TDAs and nucleon Distribution Amplitudes (DAs) in the forward and backward kinematic regimes. Assuming the validity of this factorized description, we perform feasibility studies for measuring anti pp → e{sup +}e{sup -}π{sup 0} with the PANDA detector. Detailed simulations on signal reconstruction efficiency as well as on rejection of the most severe background channel, i.e. anti pp → π{sup +}π{sup -}π{sup 0} were performed for the center-of-mass energy squared s = 5 GeV{sup 2} and s = 10 GeV{sup 2}, in the kinematic regions 3.0 < q{sup 2} < 4.3 GeV{sup 2} and 5 < q{sup 2} GeV{sup 2}, respectively, with a neutral pion scattered in the forward or backward cone vertical stroke cos θ{sub π{sup 0}} vertical stroke > 0.5 in the proton-antiproton center-of-mass frame. Results of the simulation show that the particle identification capabilities of the PANDA detector will allow to achieve a background rejection factor of 5 . 10{sup 7} (1 . 10{sup 7}) at low (high) q{sup 2} for s = 5 GeV{sup 2}, and of 1 . 10{sup 8} (6 . 10{sup 6}) at low (high) q{sup 2} for s = 10 GeV{sup 2}, while keeping the signal reconstruction efficiency at around 40%. At both energies, a clean lepton signal can be reconstructed with the expected statistics corresponding to 2 fb{sup -1} of integrated luminosity. The cross sections obtained from the simulations are used to

The source-code is available as an open-source project and is adaptable for other projects and sampling ADCs. Best performance with different types of signal sources can be achieved through flexible parameter selection. The on-line data-processing in FPGA enables to construct an almost dead-time free data acquisition system which is successfully evaluated as a first step towards building a complete trigger-less readout chain. Prototype setups are studied to determine the dead-time of the implemented algorithm, the rate of false triggering, timing performance, and event correlations.

    The PANDA code is used to construct tabular equations of state (EOS) for the detonation products of 24 explosives having CHNO compositions. These EOS, together with a reactive burn model, are used in numerical hydrocode calculations of cylinder tests. The predicted detonation properties and cylinder wall velocities are found to give very good agreement with experimental data. Calculations of flat plate acceleration tests for the HMX-based explosive LX14 are also made and shown to agree well with the measurements. The effects of the reaction zone on both the cylinder and flat plate tests are discussed. For TATB-based explosives, the differences between experiment and theory are consistently larger than for other compositions and may be due to nonideal (finite dimameter) behavior.

  1. High voltage monolithic active pixel sensors for the PANDA luminosity detector

    International Nuclear Information System (INIS)

    The PANDA-Experiment will be part of the new FAIR accelerator center at Darmstadt, Germany. It is a fixed target experiment using a antiproton beam with very high resolution for precision measurements. For a variety of measurements like energy-scans the precise determination of the luminosity is needed. The luminosity detector will determine the luminosity by measuring the angular distribution of elastically scattered antiprotons very close to the beam axis (3-8 mrad). To reconstruct antiproton tracks four layers of thinned silicon sensors with smart pixel readout on chip (HV-MAPS) will be used. Those sensors are currently under development by the Mu3e-collaboration. In the talk the concept of the luminosity measurement is shortly introduced before a summary of the status of HV-MAP prototypes and recent test beam results are presented.

    PandaX is a large upgradable liquid-xenon detector system that can be used for both direct dark-matter detection and $^{136}$Xe double-beta decay search. It is located in the Jinping Deep-Underground Laboratory in Sichuan, China. The detector operates in dual-phase mode, allowing detection of both prompt scintillation, and ionization charge through proportional scintillation. The central time projection chamber will be staged, with the first stage accommodating a target mass of about 120\\,kg. In stage II, the target mass will be increased to about 0.5\\,ton. In the final stage, the detector can be upgraded to a multi-ton target mass. In this paper a detailed description of the stage-I detector design and performance results established during the commissioning phase is presented.

  3. Measurements of photon response and light yield homogeneity with PbWO4 crystals for PANDA

    International Nuclear Information System (INIS)

    The dynamic range for the crystals of the PANDA calorimeter is foreseen to span from 10 MeV to 15 GeV in order to make reconstruction of channels with both low and high energy photons possible. The synchrotron facility MAX-Lab in Lund, Sweden, provides a unique opportunity to measure response function of crystals at energies in the low energy regime. The photon energy resolution for an array of PbWO4 crystals has been measured in the range of 10 MeV to 100 MeV. Another important feature is the homogeneity of the light yield response along the crystals. Results from these energy resolution and homogeneity measurements arre reported.

  4. An event building scenario in the trigger-less PANDA experiment

    International Nuclear Information System (INIS)

    The PANDA experiment will be running up to 2 × 107 antiproton-proton collisions per second at energies reaching 15 GeV. The lack of simple features distinguishing the interesting events from background, as well as strong pileup of events' data streams make the use of a hardware trigger impossible. As a consequence the whole data stream of about 300 GB/s has to be analyzed online, i.e: tracking, vertex finding, particle identification and event building. The GEM Tracker covers polar angles from 4 to 20 degrees in the forward direction, and can be used for the event building in a large fraction of events. In this work the analysis chain and the implemented algorithms will be presented. Moreover, the event builder prototype based on GEM Tracker data will be presented.

    Interleukin 18 (IL-18), as a member of IL-1 superfamily, is an important pleiotropic cytokine that modulates Th1 immune responses. In this report, we cloned and identified a homolog of IL-18 in giant panda (Ailuropoda melanoleuca) (designated as AmIL-18) from peripheral blood mononuclear cells stimulated with lipopolysaccharide. The open readin g frame of AmIL-18 cDNA is 579 bp encoding a deduced protein of 192 amino acids. AmIL-18 gDNA fragments contained 5 exons and 4 introns. The amino acid sequence of AmIL-18 shared 23.9 to 87.0% identity with other species. To evaluate the effects of AmIL-18 on the immune response, we expressed the recombinant AmIL-18 in Escherichia coli BL21 (DE3). The fusion protein PET-AmIL-18 was purified by nickel affinity column chromatography and verified by sodium dodecyl sulfate polyacrylamide gel electrophoresis and Western blot analysis. The biological function of purified PET-AmIL-18 was determined on mouse splenocytes by quantitative real-time polymerase chain reaction. INF-γ and other cytokines were increased when stimulated by PET-AmIL-18, particularly when combined with recombinant human interleukin 12, while a Th2-type cytokine, interleukin-4, was strikingly suppressed. These results will provide information for the potential use of recombinant proteins to manipulate the immune response in giant pandas and facilitate the study to protect this treasured species.

    A Gram-negative, aerobic, non-motile, rod-shaped bacterial strain, designated 25-1(T), was isolated from the air inside giant panda enclosures at the Chengdu Research Base of Giant Panda Breeding, China. Strain 25-1(T) grew optimally at pH 7.0-8.0, at 28-30 °C and in the presence of NaCl concentrations from 0.0% to 0.5 %. 16S rRNA gene sequence analysis indicated that strain 25-1(T) belongs to the genus Chryseobacterium within the family Flavobacteriaceae and is related most closely to C. carnis G81(T) (96.4% similarity), C. lathyri RBA2-6(T) (95.8% similarity), and C. zeae JM1085(T) (95.8% similarity). Its genomic DNA G+C molar composition was 36.2%. The major cellular fatty acids were iso-C15:0 (44.0%), iso-C17:0 3OH (19.8%) and C16:1 ω7c/16:1 ω6c (12.7%). The only isoprenoid quinone was menaquinone 6 (MK-6). The major polar lipids were phosphatidylethanolamine, two unidentified amino lipids and two unidentified lipids. The DNA-DNA relatedness between strain 25-1(T) and C. lathyri RBA2-6(T) was 38%. Phenotypic, genotypic, and phylogenetic characteristics indicated that strain 25-1(T) is a novel member of the genus Chryseobacterium, for which the name C. chengduensis sp. nov. is proposed. The type strain is 25-1(T) (CCTCC AB2015133(T)=DSM 100396(T)). PMID:27487806

    The red panda (Ailurus fulgens) is an endangered species and its present distribution is restricted to isolated mountain ranges in western China (Sichuan, Yunnan, and Tibet provinces) and the Himalayan Mountains chain of Nepal, India, Bhutan, and Burma. To examine the evolutionary history across its current range, and to assess the genetic divergence among current subspecies and population structure among different geographic locations, we sequenced mitochondrial DNA from the control region (CR) and cytochrome (cyt) b gene for 41 individuals in Sichuan, Yunnan, Tibet of China, and Burma. 25 CR haplotypes (10 for cyt b) were identified from 11 geographic locations. Only three haplotypes were shared among sample localities, including one among current subspecies. Nine haplotypes were shared with the study of Su et al. [Mol. Biol. Evol. 18 (2001) 1070]. CR haplotype diversity was high (0.95+/-0.02) and nucleotide diversity among all haplotypes was relatively low (0.018+/-0.009). Phylogenetic confirmed trees show a shallow pattern with very little structure or statistical robustness. The application of two coalescent-based tests for population growth allowed us to interpret this phylogeny as the result of a recent population expansion. Analysis of molecular variance and nested clade analysis failed to detect significant geographic structure in both data sets. The lack of significant differentiation between subspecies does not indicate the presence of evolutionary significant units. We suggest that the present population structure has resulted from habitat fragmentation and expansion from glacial refugia. Due to its habitat requirements it is likely that the red panda has undergone bottlenecks and population expansions several times in the recent past. The present population may exhibit a pattern reminiscent of a relatively recent population expansion. PMID:15904858

    The melanocortin-4 receptor (MC4R) is critical in regulating mammalian food intake and energy expenditure. Giant panda (Ailuropoda melanoleuca), famous as the living fossil, is an endangered species endemic to China. We are interested in exploring the functions of the giant panda MC4R (amMC4R) in regulating energy homeostasis and report herein the molecular cloning and pharmacology of the amMC4R. Sequence analysis revealed that amMC4R was highly homologous (>88%) at nucleotide and amino acid sequences to several mammalian MC4Rs. Western blot revealed that the expression construct myc-amMC4R in pcDNA3.1 was successfully constructed and expressed in HEK293T cells. With human MC4R (hMC4R) as a control, pharmacological characteristics of amMC4R were analyzed with binding and signaling assays. Four agonists, including [Nle(4), D-Phe(7)]-α-melanocyte stimulating hormone (NDP-MSH), α- and β-MSH, and a small molecule agonist, THIQ, were used in binding and signaling assays. We showed that amMC4R bound NDP-MSH with the highest affinity followed by THIQ, α-MSH, and β-MSH, with the same ranking order as hMC4R. Treatment of HEK293T cells expressing amMC4R with different concentrations of agonists resulted in dose-dependent increase of intracellular cAMP levels, with similar EC50s for the four agonists. The results suggested that the cloned amMC4R encoded a functional MC4R. The availability of amMC4R and its binding and signaling properties will facilitate the investigation of amMC4R in regulating food intake and energy homeostasis. PMID:26896843

    A Gram-negative, aerobic, non-motile, rod-shaped bacterial strain, designated 25-1T, was isolated from the air inside giant panda enclosures at the Chengdu Research Base of Giant Panda Breeding, China. Strain 25-1T grew optimally at pH 7.0–8.0, at 28–30 °C and in the presence of NaCl concentrations from 0.0% to 0.5 %. 16S rRNA gene sequence analysis indicated that strain 25-1T belongs to the genus Chryseobacterium within the family Flavobacteriaceae and is related most closely to C. carnis G81T (96.4% similarity), C. lathyri RBA2-6T (95.8% similarity), and C. zeae JM1085T (95.8% similarity). Its genomic DNA G+C molar composition was 36.2%. The major cellular fatty acids were iso-C15:0 (44.0%), iso-C17:0 3OH (19.8%) and C16:1 ω7c/16:1 ω6c (12.7%). The only isoprenoid quinone was menaquinone 6 (MK-6). The major polar lipids were phosphatidylethanolamine, two unidentified amino lipids and two unidentified lipids. The DNA–DNA relatedness between strain 25-1T and C. lathyri RBA2-6T was 38%. Phenotypic, genotypic, and phylogenetic characteristics indicated that strain 25-1T is a novel member of the genus Chryseobacterium, for which the name C. chengduensis sp. nov. is proposed. The type strain is 25-1T (CCTCC AB2015133T=DSM 100396T). PMID:27487806

  12. Technical design report for the PANDA (AntiProton Annihilations at Darmstadt) Straw Tube Tracker. Strong interaction studies with antiprotons

    International Nuclear Information System (INIS)

    This document describes the technical layout and the expected performance of the Straw Tube Tracker (STT), the main tracking detector of the PANDA target spectrometer. The STT encloses a Micro-Vertex-Detector (MVD) for the inner tracking and is followed in beam direction by a set of GEM stations. The tasks of the STT are the measurement of the particle momentum from the reconstructed trajectory and the measurement of the specific energy loss for a particle identification. Dedicated simulations with full analysis studies of certain proton-antiproton reactions, identified as being benchmark tests for the whole PANDA scientific program, have been performed to test the STT layout and performance. The results are presented, and the time lines to construct the STT are described. (orig.)

    Research highlights: Black-Right-Pointing-Pointer The release of large amount of non-condensable gas in the drywell has an effect of the containment pressure, but it does not block the PCCS operation. Black-Right-Pointing-Pointer Containment pressure is directly related to the amount of non-condensable vented to the wetwell. Black-Right-Pointing-Pointer Gas-stratification in PANDA DW dead-end volume determined long-term retention of non-condensable in the Drywell. - Abstract: As part of the Euratom project TEMPEST (Testing and Enhanced Modelling of Passive Evolutionary Systems Technology for Containment Cooling), a series of five tests was performed in the PANDA facility to experimentally investigate the distribution of hydrogen inside the containment and its impact on the performance of the Passive Containment Cooling System (PCCS) designed for the Economic Simplified Boiling Water Reactor (ESBWR). In a postulated severe accident a large amount of hydrogen could be released in the Reactor Pressure Vessel (RPV) as a consequence of the cladding Metal-Water (M-W) reaction and discharged together with steam to the Drywell (DW) compartment. The retention of hydrogen in the DW, instead to be vented in the Wetwell (WW), has a positive effect toward the mitigation of the system pressure build-up. Hydrogen retention in the DW is a consequence of the stratification phenomena driven by the steam-hydrogen density difference. The paper presents the experimental results of the integral Test T1.2 performed in the PANDA facility. Helium was used to simulate hydrogen and the specific PANDA facility configuration included a dead-end volume, allowing for retaining a portion of the released helium in the DW compartment. The results from Test T1.2 showed that the containment end pressure is mainly determined by the redistribution of non-condensable gas inside the containment system and the temporary deterioration of the PCCS performance during the helium release phase plays a minor

    Recent development of computed tomography and three-dimensional visualization techniques has enabled the non-destructive inspection of the endocast morphology of fossil neurocranium, the basic material for paleoneurological study. A virtual cranial endocast was reconstructed based on the first skull of the oldest giant panda, Ailuropoda microta, discovered recently and dated at more than 2 Myr (million years) ago. It was compared with that of the extant giant panda ( A. melanoleuca) and that of the polar bear ( Ursus maritimus), as well as CT slices of the late Pleistocene A. baconi. The overall endocast morphology of A. microta is more similar to that of A. baconi and A. melanoleuca than to that of U. maritimus. The absolute endocast size is the smallest in A. microta, largest in A. baconi, and intermediate in A. melanoleuca. However, the proportion of cerebral volume to total endocast size is very close to each other between the oldest and extant giant panda, as well as the sulcal length per unit area of cerebral endocast surface.

    To study the typical vaginal bacterial flora of giant pandas (Ailuropoda melanoleuca), we took vaginal swabs for the sake of bacterial isolation, from 24 healthy female giant pandas. A total of 203 isolates were identified, representing a total of 17 bacterial species. The most common bacteria isolated were Lactobacillus spp. (54.2%, 13/24), followed by Staphylococcus epidermidis (41.7%, 10/24) and Escherichia coli (33.3%, 8/24). Some opportunistic pathogenic bacteria, such as Peptostreptococcus spp., Klebsiella pneumoniae , and Proteus mirabilis , were also isolated but showed no pathology. Antimicrobial susceptibility testing of aerobic bacterial isolates was performed with the disk diffusion method. Of the 152 isolates, resistance was most frequently observed with chloramphenicol (17.8%), followed by tetracycline (14.5%), ciprofloxacin (12.5%), streptomycin (11.8%), and florfenicol (11.8%), whereas 7.2% were multidrug resistant. This is the first report of the normal culturable vaginal bacterial flora of giant pandas and the antimicrobial susceptibility patterns of the isolates. PMID:27468049

  17. Pilot factory - a Condor-based system for scalable Pilot Job generation in the Panda WMS framework

    International Nuclear Information System (INIS)

    The Panda Workload Management System is designed around the concept of the Pilot Job - a 'smart wrapper' for the payload executable that can probe the environment on the remote worker node before pulling down the payload from the server and executing it. Such design allows for improved logging and monitoring capabilities as well as flexibility in Workload Management. In the Grid environment (such as the Open Science Grid), Panda Pilot Jobs are submitted to remote sites via mechanisms that ultimately rely on Condor-G. As our experience has shown, in cases where a large number of Panda jobs are simultaneously routed to a particular remote site, the increased load on the head node of the cluster, which is caused by the Pilot Job submission, may lead to overall lack of scalability. We have developed a Condor-inspired solution to this problem, which is using the schedd-based glidein, whose mission is to redirect pilots to the native batch system. Once a glidein schedd is installed and running, it can be utilized exactly the same way as local schedds and therefore, from the user's perspective, Pilots thus submitted are quite similar to jobs submitted to the local Condor pool.

  18. Post-test sensitivity analysis of OECD/CSNI ISP42 panda experiment by Relap5 code

    International Nuclear Information System (INIS)

    The present document deals with Relap5/Mod3.2 analysis of the International Standard Problem (ISP-42) exercise performed in PANDA facility on April 21-22, 1998. PANDA is installed at PSI (Paul Scherrer Institute). PANDA is a large-scale thermal-hydraulic test facility suitable for the simulation of passive containment for Advanced Light Water Reactors (ALWR). The work focuses phase A of the ISP-42 experiment, including the break in the main steam line, and the Passive Containment Cooling System Start-Up. The objective is to investigate the start-up phenomenology of passive cooling system when steam is injected into cold vessel filled with air and to observe the resulting system behavior. A detailed nodalization was set-up at the University of Pisa, in order to model 3-D flow paths with a 1-D code. The comparison between pre-test predictions and experimental data is discussed. Overall time behavior is reasonably well predicted, showing a rather good and robust overall code behavior in the simulation of the global test scenario. The results of a preliminary post-test analysis are discussed, including the comparison with the experimental data. (authors)

    International Nuclear Information System (INIS)

    A full account is given of the design, construction and operation of an experimental apparatus for the measurement of the angular correlation of positron-annihilation radiation in two dimensions (2D ACAR). The 2D ACAR technique is insensitive to the electronic mean-free-path and can be applied to pure metals as well as non-dilute alloys and compounds to obtain valuable information on the band structure and Fermi-surface geometry. The apparatus consists of two 30 x 30 cm2 hybrid (high-density) multi-wire-chamber γ detectors at variable distances from 5 to 12 m at opposite sides of a variable temperature cryostat which contains a 6.5 T superconducting magnet. The detectors, the coded centre-of-gravity position read-out method employed, the associated electronics and computer software are described in detail. Operational characteristics and results are presented. A net detection efficiency of 6% and an angular resolution of 0.21 x 0.31 mrad2 (0.029 x 0.042 a.u.2) are reproducibly obtained. Parameters affecting the performance of the system are discussed. An improvement of the efficiency to over 10% by relatively simple measures is foreseen

    The creation of nature reserves is the most direct way to save endangered species populations and their habitat. Development of the giant panda (Ailuropoda melanoleuca) nature reserve network in China was initiated in the 1960s, though the effort to create new reserves boomed considerably after the year 2000. Given this rapid development of protected areas in panda habitats, and the potential conflicting interests between conservation administrations and local economic development, it is essential to assess the role of new nature reserves in the overall giant panda conservation effort and reserve network. We utilized data from national giant panda surveys conducted in 2000 and 2012 to compare the size, spatial use, and distribution of panda populations, as well as the habitat suitability and connectivity in the Northern Qionglai Mountains between the two survey years. Our results show that although the total giant panda population in the study area did not change remarkably, local changes did occur. Most notably, the population in Wolong Nature Reserve declined by 27.3% (N = 39) and the population in Caopo Nature Reserve increased by 71.4% (N = 29) over the 12-year study period. We also found habitat suitability and availability decreased in both Wolong (12.4%) and Caopo (7.4%), but that the relative density of giant pandas declined (19.2%) and increased (84.6%) at each site, respectively. The distance between centers of high IUA were more distant in 2012 (14.1±1.9km) than that in 2000 (6.1±0.9km; t = -7.4, df = 5, p = 0.001), showing a scattered spatial pattern. Habitat availability decreased by 42% within the corridor between the two reserves, however panda occurrences in the corridor increased 24.6%. Compared to the total number of encounters, the proportion of the corridor increased 45.76%. Our results show the importance and success of the newly established Caopo to the conservation of giant pandas, and how crucial it is to identify and repair reserve

    Daily activity rhytlms of three radio-collared captive red pandas were monitored individually at 15 minute intervals for 3 euntinuous days each month at Yele Nature Reserve, Xiangling Mountains, June- October 1995. Our data indicated that mean rate of activity [0.51 ) of captive red pandas was lower than that of wild red pandas. Three captive red pandas showed similar daily activity patterns, being least active during night and more active during daytime. Mean rate of activity during daylight (0.58)was higher than during nighttime (0.41). Daily mean durations of activity and rest were 12.21 hours and 11.79 hours, respectively. Active times of captive red pandas accounted for 50.6% of each 24 hours, of which 66.5% were recorded during daylight and 33.5% during night. Two active peaks appeared at07: 30-09: 15 and 17: 30- 19: 00. We recorded a mean of 2.17, 2.13 and 0.88 long, mid-length, and short resting bouts daily, which had mean durations of 3.47, 1.65 and 0.87 hour, respectively.Among these long rests, 46.1% occurred during daytime and 53.8% during nighttime.

    Under the current system, orthopaedic trauma surgeons must work in some form of hospital setting as our primary service involves treatment of the trauma patient. We must not forget that just as a trauma center cannot exist without our services, we cannot function without their support. As a result, a clear understanding of the balance between physicians and hospitals is paramount. Historical perspective enables physicians and hospital personnel alike to understand the evolution of hospital-physician relationship. This process should be understood upon completion of this chapter. The relationship between physicians and hospitals is becoming increasingly complex and multiple forms of integration exist such as joint ventures, gain sharing, and co-management agreements. For the surgeon to negotiate well, an understanding of hospital governance and the role of the orthopaedic traumatologist is vital to success. An understanding of the value provided by the traumatologist includes all aspects of care including efficiency, availability, cost effectiveness, and research activities. To create effective and sustainable healthcare institutions, physicians and hospitals must be aligned over a sustained period of time. Unfortunately, external forces have eroded the historical basis for the working relationship between physicians and hospitals. Increased competition and reimbursement cuts, coupled with the increasing demands for quality, efficiency, and coordination and the payment changes outlined in healthcare reform, have left many organizations wondering how to best rebuild the relationship. The principal goal for the physician when partnering with a hospital or healthcare entity is to establish a sustainable model of service line management that protects or advances the physician's ability to make impactful improvements in quality of patient care, decreases in healthcare costs, and improvements in process efficiency through evidence-based practices and protocols.

    Full Text Available La faringoamigdalitis aguda (FAA en el adulto es una de las enfermedades infecciosas más comunes en la consulta del médico de familia. La etiología más frecuente es viral. Dentro de la etiología bacteriana, el principal agente responsable es Streptococcus pyogenes o estreptococo β-hemolítico del grupo A (EBHGA, causante del 5-30% de los casos. En el manejo diagnóstico, las escalas de valoración clínica para predecir la posible etiología bacteriana, son una buena ayuda para seleccionar a qué pacientes se deben practicar las técnicas de detección rápida de antígeno estreptocócico. Es conocido que, en general, sin estas técnicas se tiende al sobrediagnóstico de FAA estreptocócica, con la consiguiente prescripción innecesaria de antibióticos, muchas veces de amplio espectro. Así, con el manejo de las escalas y la técnica de diagnóstico rápido, elaboramos los algoritmos de manejo de la FAA. Los objetivos del tratamiento son acelerar la resolución de los síntomas, reducir el tiempo de contagio y prevenir las complicaciones supurativas locales y no supurativas. Los antibióticos de elección para el tratamiento de la FAA estreptocócica son penicilina y amoxicilina. La asociación de amoxicilina y clavulánico no está indicada en el tratamiento inicial en la infección aguda. Los macrólidos tampoco son un tratamiento de primera elección; su uso debe reservarse para pacientes con alergia a la penicilina. Es importante en nuestro país adecuar tanto el diagnóstico de la FAA bacteriana y la prescripción de antibióticos a la evidencia científica disponible. La implantación de protocolos de actuación en las farmacias comunitarias puede ser de utilidad para identificar y cribar los casos que no requieran tratamiento antibiótico.

    Full Text Available Objetivo: valorar la salud y la capacidad funcional de ancianos con dependencia funcional para el autocuidado, como elementos para orientar el cuidado de enfermería y el cuidado familiar en casa. Metodología: estudio descriptivo transversal en 40 personas de 65 y más años con dependencia funcional, cuidados por familiar, en Envigado Colombia; muestreo por conveniencia. Valoración de la capacidad funcional con el índice de Katz y la escala de Lawton y Brody, ajustados según grupo de Neurociencias, Universidad de Antioquia. Hallazgos: población entre 67 y 98 años, edad promedio 84,08 años; 82,5% mujeres. Sistemas orgánicos más afectados: cardiovascular, osteomuscular y neurológico; entre 47,5% y 27,5% de los ancianos los tenían comprometidos. Se identificaron dos comportamientos: los hombres, y las personas de edad más avanzada, con mayores grados de dependencia en las actividades básicas e instrumentales; no se determinó asociación estadística por el pequeño tamaño muestral. Las actividades básicas estaban afectadas así: entre el 67,5% y el 55% de los ancianos requería ayuda; y las actividades instrumentales estuvieron comprometidas: entre el 95% y el 75% de los ancianos son totalmente dependientes en ellas. Conclusiones: Enfermería ha de considerar la valoración de la capacidad funcional articulada al estado de salud integral de los ancianos, para orientar su cuidado y apoyar a los cuida-dores familiares. Esto además previene dependencias de cuidado innecesarias que estarían en contra de las aspiraciones del adulto mayor como individuo autónomo e independiente. Es tarea de profesionales en enfermería capacitar a cuidadores familiares sobre valoración de la capacidad funcional.

A busca de artigos científicos foi realizada nas bases de dados PubMed, MedLine (Literatura Internacional em Ciências e Saúde, LILACS (Literatura Latino Americana e do Caribe em Ciências e Saúde e Cochrane entre 1995 e dezembro de 2008 utilizando as palavras-chaves: physical therapy, mobilization and intensive care unit. Para efeito de comparação foram selecionados estudos controlados, randomizados e prospectivos, abordando o tema fisioterapia motora para pacientes adultos em unidade de terapia intensiva. Estudos em pediatria, experimentais, revisões sistemáticas e metanálises foram excluídos. Dos 121 artigos encontrados, apenas 4 preencheram aos critérios de inclusão. Dentre estes, três artigos abordavam sobre a aplicação da fisioterapia motora precoce em pacientes com diagnósticos variados, mostrando que estes indivíduos saíram mais cedo da cama, deambularam em menos dias e tiveram um menor tempo de permanência na unidade de terapia intensiva e no hospital. Além disso, os pacientes que receberam fisioterapia motora precoce apresentaram um menor tempo de ventilação mecânica. Já o outro artigo compara a aplicação da eletroestimulação associada à fisioterapia em pacientes com doença pulmonar obstrutiva crônica, mostrando um aumento na força muscular e menor tempo para a transferência destes indivíduos da cama para a cadeira em relação aos que receberam apenas fisioterapia. Os riscos da imobilização em doentes críticos ventilados mecanicamente não são bem esclarecidos. Entretanto, é evidente que os sobreviventes apresentem fraqueza e fadiga persistente, prejudicando sua qualidade de vida. A mobilização precoce é uma área nova e com poucas evidências até o momento.

Se describen ocho pacientes adultos con cuadros de microangiopatía trombótica, que fueron atendidos en el Hospital Italiano de Buenos Aires entre 2003 y 2004. El promedio de edad fue de 40 años, con igual proporción de hombres y mujeres. En cuatro de los ocho pacientes descriptos el diagnóstico se realizó al ingreso. Cuatro pacientes evolucionaron con características de SUH, tres como PTT y uno como MAT del embarazo. Todos los pacientes presentaron trombocitopenia y anemia hemolítica microangiopática. La insuficiencia renal fue la tercera característica más frecuente. Aquellos con diagnóstico de PTT presentaron los cuadros de mayor gravedad. Todos los pacientes fueron tratados con plasmaféresis. El tratamiento inmunosupresor también fue utilizado. Cuatro pacientes se recuperaron completamente, 2 fallecieron, 1 permanece con insuficiencia renal crónica con requerimiento de hemodiálisis y 1 fue colectomizado. Las MAT son desórdenes oclusivos de la microcirculación, con repercusión sistémica y/o renal. Existe superposición de los cuadros de PTT/SUH, y éstos pueden ser idiopáticos o secundarios. La importancia de un diagnóstico y tratamiento precoz radica en su elevada morbimortalidad. Entre los diagnósticos diferenciales figuran la sepsis, las enfermedades oncológicas, las vasculitis sistémicas, la eclampsia y otros.

  1. The pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS) etiology for tics and obsessive-compulsive symptoms: hypothesis or entity? Practical considerations for the clinician.

    Science.gov (United States)

    Kurlan, Roger; Kaplan, Edward L

    2004-04-01

    Clinicians have been faced with much publicity and contradictory scientific evidence regarding a recently described condition termed pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS). It has been proposed that children with PANDAS experience tics, obsessive-compulsive behavior, and perhaps other neuropsychiatric symptoms as an autoimmune response to streptococcal infection. We review current scientific information and conclude that PANDAS remains a yet-unproven hypothesis. Until more definitive scientific proof is forthcoming, there seems to be insufficient evidence to support 1) routine microbiologic or serologic testing for group A streptococcus in children who present with neuropsychiatric symptoms or 2) the clinical use of antibiotic or immune-modifying therapies in such patients. The optimum diagnostic and therapeutic approach awaits the results of additional research studies. PMID:15060240

  5. Giant Panda Maternal Care: A Test of the Experience Constraint Hypothesis

    Snyder, Rebecca J.; Perdue, Bonnie M.; Zhang, Zhihe; Maple, Terry L.; Charlton, Benjamin D.

    2016-01-01

    The body condition constraint and the experience condition constraint hypotheses have both been proposed to account for differences in reproductive success between multiparous (experienced) and primiparous (first-time) mothers. However, because primiparous mothers are typically characterized by both inferior body condition and lack of experience when compared to multiparous mothers, interpreting experience related differences in maternal care as support for either the body condition constraint hypothesis or the experience constraint hypothesis is extremely difficult. Here, we examined maternal behaviour in captive giant pandas, allowing us to simultaneously control for body condition and provide a rigorous test of the experience constraint hypothesis in this endangered animal. We found that multiparous mothers spent more time engaged in key maternal behaviours (nursing, grooming, and holding cubs) and had significantly less vocal cubs than primiparous mothers. This study provides the first evidence supporting the experience constraint hypothesis in the order Carnivora, and may have utility for captive breeding programs in which it is important to monitor the welfare of this species’ highly altricial cubs, whose survival is almost entirely dependent on receiving adequate maternal care during the first few weeks of life.

    The ATLAS Experiment at the Large Hadron Collider has collected data during Run 1 and is ready to collect data in Run 2. The ATLAS data are distributed, processed and analysed at more than 130 grid and cloud sites across the world. At any given time, there are more than 150,000 concurrent jobs running and about a million jobs are submitted on a daily basis on behalf of thousands of physicists within the ATLAS collaboration. The Production and Distributed Analysis (PanDA) workload management system has proved to be a key component of ATLAS and plays a crucial role in the success of the large-scale distributed computing as it is the sole system for distributed processing of Grid jobs across the collaboration since October 2007. ATLAS user jobs are executed on worker nodes by pilots sent to the sites by pilot factories. This pilot architecture has greatly improved job reliability and although it has clear advantages, such as making the working environment homogeneous by hiding any potential heterogeneities, the ...

  9. Design optimisation for the silicon micro-strip part of the PANDA Micro-Vertex-Detector

    International Nuclear Information System (INIS)

    The PANDA experiment is one of the key projects at the future FAIR facility, which is under construction at GSI, Darmstadt. The Micro- Vertex-Detector (MVD) is the innermost detector part of the experiment. Silicon sensors are used for high precision tracking. The outer detector layers are equipped with double-sided silicon strip detectors. An optimisation has been accomplished for the layout of the MVD starting with the extraction of design parameters to qualify the physics performance of the detector. A clear definition of the requirements for the frontend electronics, and a precise description of the detector modules, the cooling system and the support structure are necessary to obtain realistic values concerning the material budget, the thermal load and space requirements. Altogether, this data can be taken as input for physics and engineering simulations. In parallel, prototypes for the detector modules and support structures are under development allowing the measurement of key parameters and the demonstration of the technical feasibility for the proposed concept. In consequence, the optimization process to be illustrated for the silicon micro-strip part of the MVD is based on both simulation results and experimental data.

    We exploit data from the Pan-Andromeda Archaeological Survey (PAndAS) to study the extended structures of M31's dwarf elliptical companions, NGC147 and NGC185. Our wide-field, homogeneous photometry allows to construct deep colour-magnitude diagrams (CMDs) which reach down to $\\sim3$ mag below the red giant branch (RGB) tip. We trace the stellar components of the galaxies to surface brightness of $\\mu_g \\sim 32$ mag arcsec$^{-2}$ and show they have much larger extents ($\\sim5$ kpc radii) than previously recognised. While NGC185 retains a regular shape in its peripheral regions, NGC147 exhibits pronounced isophotal twisting due to the emergence of symmetric tidal tails. We fit single Sersic models to composite surface brightness profiles constructed from diffuse light and star counts and find that NGC147 has an effective radius almost 3 times that of NGC185. In both cases, the effective radii that we calculate are larger by a factor of $\\sim2$ compared to most literature values. We also calculate revised total...

    The paper reports the results of the assessment of the GOTHIC code using the data of four basic tests with condensation performed in the PANDA large-scale facility. Three of these experiments featured vertical injection, and in one the transient response due to a high-momentum horizontal injection (jet) was investigated. The injected fluid was either saturated steam or a superheated mixture of steam and helium, and the fluid initially present in the vessels was pure air. The simulations were carried out using a detailed three-dimensional representation of the vessels. In general, the results of the simulations, which used a relatively coarse mesh, were in good agreement with the data. Limitations in modelling local phenomena controlled by complex flow patterns (e.g. heat transfer in the region of an impinging jet) and the need for refined meshes to reproduce certain aspects of the transients (e.g. erosion of the interface between layers of different gas composition) were also identified. Finally, the analyses indicated that in two tests the role played by re-vaporisation of the condensate film was unexpectedly large, and this effect should be more carefully considered in the containment analyses and future model developments.

    Panda-X is a liquid xenon dual-phase detector for the Dark Matter Search. The first modestly-sized module will soon be installed in the China JinPing Deep Underground Laboratory in Sichuan province, P.R. China. The cryogenics system is designed to handle much larger detectors, even the final version in the ton scale. Special attention has been paid to the reliability, serviceability, and adaptability to the requirements of a growing experiment. The system is cooled by a single Iwatani PC150 Pulse Tube Refrigerator. After subtracting all thermal losses, the remaining cooling power is still 82W. The fill speed was 9 SLPM, but could be boosted by LN2 assisted cooling to 40 SLPM. For the continuous recirculation and purification through a hot getter, a heat exchanger was employed to reduce the required cooling power. The recirculation speed is limited to 35 SLPM by the gas pump. At this speed, recirculation only adds 18.5 W to the heat load of the system, corresponding to a 95.2 % efficiency of the heat exchanger...

  14. Simulation of the panda test for the ISP42 using the Cathare code

    International Nuclear Information System (INIS)

    The extensive use of passive safety systems for decay heat removal proposed in some evolutionary LWR design requires an extension of the validation domain of the T/H advanced codes for the safety analysis of the future reactors. A task of the co-operation between ENEA (Italy) and CEA (France) on advanced reactors is specifically devoted to assess the capability of CATHARE (T/H best estimate French code) to simulate such systems. Within this framework ENEA and CEA took part in the CSNI International Standard Problem (ISP) 42 based on a test in the PANDA facility (PSI, CH). Phases A, C and D of the ISP were chosen by ENEA and CEA for CATHARE pre- and post-test calculations, since these phases dealt with issues already object of previous collaborations on the CATHARE assessment: pool immersed heat exchangers operating at low pressure, steam condensation in presence of non-condensable gases in tubes, coupling between primary system and containment. The results here presented concern the second part of the ISP42 performed as a post-test analysis, where the analytical model used for the first part, conducted as a double-blind exercise, has been substantially improved.

Responder a essa indagação possui relevância para a formação ética e moral dos alunos devido a duas razões principais: a primeira refere-se ao desenvolvimento moral do adolescente; a segunda, à aparente deserção do espaço público por parte dos jovens em favor do espaço privado. Nesse sentido, o objetivo do presente trabalho foi verificar como os jovens julgam moralmente os adultos e se, de fato, eles operam uma clara cisão entre as esferas privada e pública. Foram realizadas separadamente duas pesquisas: no estudo 1 (E1, utilizou-se um questionário fechado de 24 questões e duas questões abertas; no estudo 2 (E2, além da aplicação de um questionário com 14 perguntas, foi realizado um debate em grupo acerca delas. É importante ressaltar que, neste artigo, são analisadas tanto questões presentes nos dois estudos, quanto algumas presentes apenas no E1. Os resultados obtidos mostram certa desconfiança dos jovens em relação à moralidade dos adultos. A maioria não os considera pessoas éticas e, de forma geral, critica sua condução da esfera pública. Além disso, os jovens questionam as virtudes dos adultos e consideram o egoísmo como o maior defeito deles, associando-o a uma preocupação exclusiva com a esfera privada. Dividem-se quanto à sabedoria, à responsabilidade e à confiança atribuída aos adultos de hoje. Os dados apontam, ainda, que a imagem do adulto apresentada é relativizada a partir da distinção entre os adultos da esfera pública e aqueles da esfera privada.The present study core issue is, how do today's youth judge adults concerning their moral criteria?

    Is it possible that Giant Panda (Ailuropoda melanoleuca) post-thawed sperm fertilization is improved with pentoxifylline (PF),platelet activated factor (PAF) and prostaglandin F 2-alpha (PGF2α)? In our study Giant Panda post-thawed sperm was incubated in Ham's F-10 medium with different concentration of PF,PAF and PGF2α,under 37℃.The effects of PF,PAF and PGF2α,on Giant Panda post-thawed sperm fertility were evaluated through sperm motility,survival time,sperm membrane integrity,acrosome state and heterospecific egg penetration.The results were that PF,PAF and PGF2α all can affect Giant Panda post-thawed sperm in vitro fertilizing capability.In the experiment:1 mg·Ml-1 PF was most suitable for improving Giant Panda post-thawed sperm in vitro fertilizing capability.In the 1 mg·Ml-1 PF group,sperm survival time was (15.33±4.73) h,the heterospecific egg penetration was 51.44% after incubating for 4 hours,the heterospecific egg penetration was 7.49% after incubating for 6 hours.The results of the 1 mg·Ml-1 PF group were significantly higher than those of the control group (P<0.01).The results were also higher than those of the other treatment groups;Treated Giant Panda post-thawed sperm with 50 ng·Ml-1 PAF had a better effect than 100 ng·Ml-1 PAF,but the sperm fertilizing capability was damaged when incubation time exceeded 2 hours;50 ng·Ml-1PGF2α,had no significant effect on Giant Panda postthawed sperm,but when the PGFzα treated concentration was increased,sperm in vitro fertilizing capability decreased because of the damaged motility and declined acrosomal reaction rate.The conclusions suggest that it is possible to improve post-thawed Giant Panda sperm fertility with 1 mg·Ml-1 PF.

    Full Text Available RPLP1 is one of acidic ribosomal phosphoproteins encoded by RPLP1 gene, which plays an important role in the elongation step of protein synthesis. The cDNA of RPLP1 was cloned successfully for the first time from the Giant Panda (Ailuropoda melanoleuca using RT-PCR technology, which was also sequenced, analyzed preliminarily and expressed in E.coli. The cDNA fragment cloned is 449bp in size, containing an open reading frame of 344bp encoding 114 amino acids. Alignment analysis indicated that the nucleotide sequence and the deduced amino acid sequence are highly conserved to other five species studied, including Homo sapiens, Mus musculus, Rattus norvegicus, Bos Taurus and Sus scrofa. The homologies for nucleotide sequences of Giant Panda PPLP1 to that of these species are 92.4%, 89.8%, 89.0%, 91.3% and 87.5%, while the homologies for amino acid sequences are 96.5%, 94.7%, 95.6%, 96.5% and 88.6%. Topology prediction showed there are three Casein kinase II phosphorylation sites and two N-myristoylation sites in the RPLP1 protein of the Giant Panda (Ailuropoda melanoleuca. The RPLP1 gene was overexpressed in E. coli and the result indicated that RPLP1 fusion with the N-terminally His-tagged form gave rise to the accumulation of an expected 18kDa polypeptide, which was in accordance with the predicted protein and could also be used to purify the protein and study its function.

  20. Experimental Investigation In The PANDA Facility Of The Impact Of A Hydrogen Release On Passive Containment Cooling Systems

    International Nuclear Information System (INIS)

    The large-scale, thermal-hydraulics PANDA facility has been used in the past for investigating passive decay-heat removal systems and related containment phenomena for a number of next-generation Light Water Reactors. Passive Containment Condenser (PCC) systems operate by transferring heat via steam condensation from inside the containment to outside, and serve to mitigate pressure build-up in the event of steam discharge from the primary circuit. Five new integral tests have recently been performed in the context of the 5th European Framework Program project TEMPEST. One main objective was to assess the influence of a light gas (hydrogen) on the performance of the Passive Containment Cooling System (PCCS). Hydrogen release in the case of a severe accident is simulated in PANDA by injecting helium with steam into the Drywell. In addition, the impact of a new accident-mitigating design feature, the Drywell Gas Re-Circulation System (DGRS), on the long-term containment behaviour was tested. Another important objective was also to provide relevant data for the validation of modern 3/4 mainly Computational Fluid Dynamics (CFD) 3/4 codes. The paper reports main observations from two of these new integral tests in which standard PANDA instrumentation has provided important data concerning system response when helium is released in the course of the transient. The results show that some important stratification phenomena have occurred, as a result of the buoyant flow generated by the helium injection. The resulting temperature and concentration measurements show how helium is being distributed in the Drywell (DW) volume during the helium injection phase, and how helium is retained or vented out of these vessels once the injection stops. The paper includes some discussion concerning the influence of gas mixing and stratification and the effect of the DGRS on PCC performance and system pressure build-up. (author)

    In natural environment,tamish was observed on the surface of historic and contemporary gold coins in several countries.Few years after the emergence of panda gold coins,several red spots were appeared on the surface.To identify the stains and to examine the spots,optical microscope (OM),scanning electron microscope (SEM),electron microprobe analysis (EMPA),X-ray photoelectron spectroscopy (XPS),and X-ray diffraction (XRD) were used.It was found by microscopic observation that the stain has a dark blue central area surrounded by a large area with a nuance of colors from brown to red.Red spots usually contain holes in the center,which are distributed along the forging stress zones formed in the struck process.From the surface analyses using EMPA,sulfur and silver are detected besides gold, and the contents of Ag and S at the tarnish part are higher than those at the other part. Furthermore,distributions of Ag and S are correlated with the morphology of stains. XPS shows that components of stains are Ag2S and Ag2SO4 and the former is much predominant.These results are confirmed using XRD analysis.Accelerated tarnish test of gold in an atmosphere containing sulfur compound proves that the similar phenomenon appears when a small amount of silver is present on the surface of gold.It can be concluded that the occurrence of tarnish stains is caused by the presence of Ag and S.

    Ursids (bears) in general, and giant pandas in particular, are highly altricial at birth. The components of bear milks and their changes with time may be uniquely adapted to nourish relatively immature neonates, protect them from pathogens, and support the maturation of neonatal digestive physiology. Serial milk samples collected from three giant pandas in early lactation were subjected to untargeted metabolite profiling and multivariate analysis. Changes in milk metabolites with time after birth were analysed by Principal Component Analysis, Hierarchical Cluster Analysis and further supported by Orthogonal Partial Least Square-Discriminant Analysis, revealing three phases of milk maturation: days 1–6 (Phase 1), days 7–20 (Phase 2), and beyond day 20 (Phase 3). While the compositions of Phase 1 milks were essentially indistinguishable among individuals, divergences emerged during the second week of lactation. OPLS regression analysis positioned against the growth rate of one cub tentatively inferred a correlation with changes in the abundance of a trisaccharide, isoglobotriose, previously observed to be a major oligosaccharide in ursid milks. Three artificial milk formulae used to feed giant panda cubs were also analysed, and were found to differ markedly in component content from natural panda milk. These findings have implications for the dependence of the ontogeny of all species of bears, and potentially other members of the Carnivora and beyond, on the complexity and sequential changes in maternal provision of micrometabolites in the immediate period after birth.

    We present a generic algorithm to search for dwarf galaxies in photometric catalogs and apply it to the Pan-Andromeda Archaeological Survey (PAndAS). The algorithm is developed in a Bayesian framework and, contrary to most dwarf galaxy search codes, makes use of both the spatial and color-magnitude information of sources in a probabilistic approach. Accounting for the significant contamination from the Milky Way foreground and from the structured stellar halo of the Andromeda galaxy, we recover all known dwarf galaxies in the PAndAS footprint with high significance, even for the least luminous ones. Some Andromeda globular clusters are also recovered and, in one case, discovered. We publish a list of the 143 most significant detections yielded by the algorithm. The combined properties of the 39 most significant isolated detections show hints that at least some of these trace genuine dwarf galaxies, too faint to be individually detected. Follow-up observations by the community are mandatory to establish which are real members of the Andromeda satellite system. The search technique presented here will be used in an upcoming contribution to determine the PAndAS completeness limits for dwarf galaxies. Although here tuned to the search of dwarf galaxies in the PAndAS data, the algorithm can easily be adapted to the search for any localized overdensity whose properties can be modeled reliably in the parameter space of any catalog.

    Autoimmunity associated with a streptococcal infection has been proposed as a pathogenic mechanism for obsessive-compulsive disorder (OCD) in children. Antibrain antibody profiles were compared in children with OCD-only (n = 13; 14.1 +/- 3.1 years), OCD+PANDAS (n = 20; 11.3 +/- 1.5 years), OCD+Chronic Tic Disorder (n = 23; 13.4 +/- 3.5 years), and controls (n = 29; 12.4 +/- 2.4 years) using ELISA (orbitofrontal (OFC) and dorsolateral prefrontal cortex (DLPFC), caudate (CD), cingulate gyrus (CG)), immunoblotting (four regions plus putative antigens), and immunohistochemistry. ELISA and immunohistochemistry showed no differences among groups. Immunoblot showed that a greater percentage of individuals in the OCD+PANDAS cohort had reactive bands at 27 kDa (CD, CG, DLPFC), 36 kDa (CD), and 100 kDa (CD, OFC) and increased peak height at 67 kDa (all regions). Immunoblotting studies using the putative antigens (pyruvate kinase M1, aldolase C, alpha- and gamma-enolase) did not differ among groups. ASO titers were similar in all groups and did not correlate with immunoassays. It remains controversial whether childhood OCD is associated with autoimmune mechanisms. PMID:19628285

    The giant panda (Ailuropoda melanoleuca) is currently threatened by habitat loss, fragmentation, and human persecution. Its dietary specialization, habitat isolation, and reproductive constraints have led to a perception that this is a species at an "evolutionary dead end," destined for deterministic extinction in the modern world. Here we examine this perception by a comprehensive investigation of its genetic diversity, population structure, and demographic history across its geographic range. We present analysis of 655 base pairs of mitochondrial (mt) control region (CR) DNA and 10 microsatellite loci for samples from its 5 extant mountain populations (Qinling, Minshan, Qionglai, Liangshan, and Lesser Xiangling). Surprisingly, extant populations display average to high levels of CR and microsatellite diversity compared with other bear species. Genetic differentiation among populations was significant in most cases but was markedly higher between Qinling and the other mountain ranges, suggesting, minimally, that the Qinling population should comprise a separate management unit for conservation purposes. Recent demographic inference using microsatellite markers demonstrated a clear genetic signature for population decline starting several thousands years ago or even further back in the past, and being accelerated and enhanced by the expansion of human populations. Importantly, these data suggest that the panda is not a species at an evolutionary "dead end," but in common with other large carnivores, has suffered demographically at the hands of human pressure. Conservation strategies should therefore focus on the restoration and protection of wild habitat and the maintenance of the currently substantial regional genetic diversity, through active management of disconnected populations.

  19. New LUX and PandaX-II Results Illuminating the Simplest Higgs-Portal Dark Matter Models

    CERN Document Server

    He, Xiao-Gang

    2016-01-01

    Direct searches for dark matter (DM) by the LUX and PandaX-II Collaborations employing xenon-based detectors have recently come up with the most stringent limits to date on the elastic scattering of DM off nucleons. For Higgs-portal scalar DM models, the new results have precluded any possibility of accommodating low-mass DM as suggested by the DAMA and CDMS II Si experiments utilizing other target materials, even after invoking isospin-violating DM interactions with nucleons. In the simplest model, SM+D, which is the standard model plus a real scalar singlet named darkon acting as the DM candidate, the LUX and PandaX-II limits rule out DM masses from 5 GeV to about 330 GeV, except a small range around the resonant point at half of the Higgs mass where the interaction cross-section is near the neutrino-background floor. In the THDMII+D, which extends the SM+D by the addition of another Higgs doublet, the region excluded in the SM+D by the direct searches can be recovered due to suppression of the DM effective...
