Cathodoluminescence Analysis of Grain Boundaries and Grain Interiors in Thin-Film CdTe

We used low-temperature cathodoluminescence (CL) spectrum imaging (CLSI) with nanoscale spatial resolution to examine charge-carrier recombination and defects at grain boundaries (GBs) and grain interiors (GIs) in as-deposited and CdCl2-treated CdTe thin films. Supporting time-resolved photoluminescence, T = 4 K photoluminescence, secondary ion mass spectrometry, and electron backscatter diffraction measurements were conducted on the same films. Color-coded maps of the luminescence transition energies (photon energy maps) were used to analyze the qualitative characteristics of the CLSI data. We applied an image analysis algorithm to the pixels in grayscale CL intensity images to compare the luminescence intensities and spectra at the GIs and GBs quantitatively and with statistical relevance. Our results show that GBs in as-deposited films are active recombination centers and are thus harmful to solar cell operation. CL GB defect contrast is quantifiably reduced for the CdCl2-treated film, which is direct evidence of passivation of deep GB core states resulting from the treatment. However, the CdCl2 treatment is not a perfect fix for GB recombination, and GB recombination may still be limiting performance in CdCl2-treated devices.
Enhanced structural analysis for C code reconstruction from IR code

Modern compilers parse their input, which usually is a high-level programming language, and then convert the resulting parse tree into an intermediate representation (IR). This IR has the important property of being source language and target processor independent, which allows for generalized optimizations. This flexibility, however, also discards some of the high-level properties of the source language. In this paper we present an analysis that can extract most of the control flow structures typically found in the C programming language from a medium level IR. Mirtoc is an implementation of this analysis for the specific case of CCMIR, the IR used in ACE's CoSy® compiler framework. A compiler based on mirtoc is able to emit C code that is well structured, readable by a human and can be compiled by a back end compiler with relatively low overhead. This enables the use of optimizers based on medium level IRs in a source-to-source flow.
GOstat: find statistically overrepresented Gene Ontologies within a group of genes.

SUMMARY Modern experimental techniques, as for example DNA microarrays, as a result usually produce a long list of genes, which are potentially interesting in the analyzed process. In order to gain biological understanding from this type of data, it is necessary to analyze the functional annotations of all genes in this list. The Gene-Ontology (GO) database provides a useful tool to annotate and analyze the functions of a large number of genes. Here, we introduce a tool that utilizes this information to obtain an understanding of which annotations are typical for the analyzed list of genes. This program automatically obtains the GO annotations from a database and generates statistics of which annotations are overrepresented in the analyzed list of genes. This results in a list of GO terms sorted by their specificity. AVAILABILITY Our program GOstat is accessible via the Internet at http://gostat.wehi. edu.au
Vispark: GPU-accelerated distributed visual computing using spark

With the growing need of big data processing in diverse application domains, MapReduce (e.g., Hadoop) becomes one of the standard computing paradigms for large-scale computing on a cluster system. Despite of its popularity, the current MapReduce framework suffers from inflexibility and inefficiency inherent from its programming model and system architecture. In order to address these problems, we propose Vispark, a novel extension of Spark for GPU-accelerated MapReduce processing on array-based scientific computing and image processing tasks. Vispark provides an easy-to-use, Python-like high-level language syntax and a novel data abstraction for MapReduce programming on a GPU cluster system. Vispark introduces a programming abstraction for accessing neighbor data in the mapper function, which greatly simplifies many image processing tasks using MapReduce by reducing memory footprints and bypassing the reduce stage. We demonstrate the performance of our prototype system on several visual computing tasks, such as image processing, and K-means clustering.
The effect of a task-oriented intervention on arm function in people with stroke: a randomized controlled trial

Objective: To evaluate the efficacy of a task-oriented intervention in enhancing arm function in people with stroke. Design: Two-centre, observer-blinded, stratified, block-randomized controlled trial. Setting: General community. Patients: Ninety-one individuals within one year of a first or recurrent stroke consented to participate between May 2000 and February 2003. Interventions: The experimental intervention involved practice of functional, unilateral and bilateral tasks that were designed to improve gross and fine manual dexterity whereas the control intervention was composed of walking tasks. Members in both groups participated in three sessions a week for six weeks. Main outcome measure(s): The primary test of arm function was the Box and Block Test. Secondary tests included the Nine-Hole Peg Test, maximal grip strength, the Test d'Evaluation des Membres supé rieurs des Personnes Agées (TEMPA) and the Stroke Rehabilitation Assessment of Movement. Results: Results are for the more affected arm. Baseline performance on the Box and Block Test was an average of 26 blocks (standard deviation (SD=16) in the experimental group (n=47) and 26 blocks (Sd=18) in the control group (n=44). These values represent approximately 40% of age-predicted values. Values for the postintervention evaluation were an average of 28 (SD=17) and 28 (SD=19) blocks for the experimental and control group respectively. No meaningful change on other measures of arm function was observed. Conclusions: A task-oriented intervention did not improve voluntary movement or manual dexterity of the affected arm in people with chronic stroke.
A Study on the Effect of Web Live Broadcast on Consumers’ Willingness to Purchase

E-commerce live broadcast is a kind of video live in the e-commerce platform. As an innovation of entrepreneurial marketing in the new media era, it quickly becomes the most important marketing method for many e-commerce sellers. Based on the characteristics of web live broadcast, this paper studies the path model of relationship between live video and customers’ purchase intention from the perspective of telepresence. Through the empirical analysis, it is found that the vividness, interactivity and authenticity of live video enhance consumers’ purchasing intention by affecting consumers’ sense of immediacy and trust. Research results affirm the rationality for e-commerce sellers to introduce live broadcast marketing. Studies of detailed influencing paths allow sellers to evaluate marketing activities from the perspective of customers’ mentality, to better understand the effect of live broadcast and finally to optimize marketing strategies.
Changes in central steroid receptor expression, steroid synthesis, and dopaminergic activity related to the reproductive cycle of the ring dove

This review examines possible neural mechanisms involved in the expression of parental behavior in the ring dove, Streptopelia risoria. This avian species has proved an excellent animal model for studies concerning endocrine‐behavior interactions for many years. Studies were performed to localize the expression of central androgen and progesterone receptor in both sexes. Expression of androgen receptor (androgen receptor immunoreactivity, AR‐ir) was widespread but increased, similarly in both sexes, with increasing day‐length. Progesterone receptor‐immunoreactivity (PR‐ir) was more localized in several discrete areas of the hypothalamus. Similarly, no sex differences were observed in PR‐ir, and expression increased in birds maintained on long days. AR‐ir demonstrated dramatic changes over the breeding cycle, being greatest in courting birds and almost undetectable in parenting birds of both sexes brooding their young. PR‐ir showed a differential expression over the breeding cycle relative to its hypothalamic localization. PR‐ir decreased in the tuberal hypothalamic area in brooding birds of both sexes; whereas in the preoptic area, PR‐ir was maintained. Significant increases in dopaminergic activity during the parenting phase of the breeding cycle occurred in specific neural regions including the PVM and DMA. Studies demonstrated the ability of the diencephalon of both sexes of the ring dove brain to synthesize progesterone, with indications that in the male brooding dove, synthesis is increased. Finally, a model is presented that proposes a mechanism whereby these central systems may interact to result in the expression of full parental behavior in both sexes of the ring dove. Microsc. Res.

Spatial variation in coral reef fish and benthic communities in the central Saudi Arabian Red Sea

Local-scale ecological information is critical as a sound basis for spatial management and conservation and as support for ongoing research in relatively unstudied areas. We conducted visual surveys of fish and benthic communities on nine reefs (3–24 km from shore) in the Thuwal area of the central Saudi Arabian Red Sea. Fish biomass increased with increasing distance from shore, but was generally low compared to reefs experiencing minimal human influence around the world. All reefs had a herbivore-dominated trophic structure and few top predators, such as sharks, jacks, or large groupers. Coral cover was considerably lower on inshore reefs, likely due to a 2010 bleaching event. Community analyses showed inshore reefs to be characterized by turf algae, slower-growing corals, lower herbivore diversity, and highly abundant turf-farming damselfishes. Offshore reefs had more planktivorous fishes, a more diverse herbivore assemblage, and faster-growing corals. All reefs appear to be impacted by overfishing, and inshore reefs seem more vulnerable to thermal bleaching. The study provides a description of the spatial variation in biomass and community structure in the central Saudi Arabian Red Sea and provides a basis for spatial prioritization and subsequent marine protected area design in Thuwal.
Design of sparse non-periodic narrow-band and wide-band FRM-like FIR filters

In this work, a design method for narrow-band and wide-band frequency-response masking FIR filters is proposed. As opposed to most previous works, the design method is not based on a periodic model filter. Instead, the masking filter is designed for a given stopband edge. The model filter design is based on optimizing the sparseness of the filter, and, hence, the resulting model filter is not required to be periodic.

Using Technology Acceptance Model to Evaluate Users' Attitude and Intention of Uses

Many empirical studies have pointed out that the technology acceptance model (TAM) can be used to explain whether users can accept a new information technology. Therefore, this study has adopted TAM to investigate external factors that affect gamers’ acceptance of online games. In this study, system quality, information quality, and service provider’s characteristics were taken as external variables. It was discovered that in the aspect of perceptions, system quality had positive effects on perceived ease of use and perceived usefulness. Service provider’s characteristics had positive effects on perceived usefulness and perceived trust. Besides, in the relationship between user’s perception and attitude and intention, the research finding was consistent with TAM has suggested; i.e. perceived ease of use had positive effects on perceived usefulness and user’s attitude, and perceived usefulness had positive effect on user’s attitude. Finally, user’s perceived trust and attitude would be positively correlated with user’s intention of use.
Fast Versus Slow Recruitment Maneuver at Different Degrees of Acute Lung Inflammation Induced by Experimental Sepsis

BACKGROUND:Large tidal volume (VT) breaths or “recruitment maneuvers” (RMs) are used commonly to open collapsed lungs, but their effectiveness may depend on how the RM is delivered. We hypothesized that a stepped approach to RM delivery (“slow” RM) compared with a nonstepped (“fast” RM), when followed by decremental positive end-expiratory pressure (PEEP) titration to lowest dynamic elastance, would (1) yield a more homogeneous inflation of the lungs, thus reducing the PEEP obtained during post-RM titration; (2) produce less lung morphofunctional injury, regardless of the severity of sepsis-induced acute lung inflammation; and (3) result in less biological damage in severe, but not in moderate, acute lung inflammation. METHODS:Sepsis was induced by cecal ligation and puncture surgery in 51 Wistar rats. After 48 hours, animals were anesthetized, mechanically ventilated (VT = 6 mL/kg), and stratified by PO2/fraction of inspired oxygen ratio into moderate (≥300) and severe (<300) acute lung inflammation groups. Each group was then subdivided randomly into 3 subgroups: (1) nonrecruited; (2) RM with continuous positive airway pressure (30 cm H2O for 30 seconds; CPAPRM or fast RM); and (3) RM with stepwise airway pressure increase (5 cm H2O/step, 8.5 seconds/step, 6 steps, 51 seconds; STEPRM or slow RM), with a maximum pressure hold for 10 seconds. All animals underwent decremental PEEP titration to determine the level of PEEP required to optimize dynamic compliance after RM and were then ventilated for 60 minutes with VT = 6 mL/kg, respiratory rate = 80 bpm, fraction of inspired oxygen = 0.4, and the newly adjusted PEEP for each animal. Respiratory mechanics, hemodynamics, and arterial blood gases were measured before and at the end of 60-minute mechanical ventilation. Lung histology and biological markers of inflammation and damage inflicted to endothelial cells were evaluated at the end of the 60-minute mechanical ventilation. RESULTS:Respiratory system mean airway pressure was lower in STEPRM than that in CPAPRM. The total RM time was greater, and the RM rise angle was lower in STEPRM than that in CPAPRM. In both moderate and severe acute lung inflammation groups, STEPRM reduced total diffuse alveolar damage score compared with the score in nonrecruited rats. In moderate acute lung inflammation, STEPRM rats compared with CPAPRM rats had less endothelial cell damage and angiopoietin (Ang)-2 expression. In severe acute lung inflammation, STEPRM compared with CPAPRM reduced hyperinflation, endothelial cell damage, Ang-2, and intercellular adhesion molecule-1 expressions. RM rise angle correlated with Ang-2 expression. CONCLUSIONS:Compared with CPAPRM, STEPRM reduced biological markers associated with endothelial cell damage and ultrastructural endothelial cell injury in both moderate and severe sepsis-induced acute lung inflammation.
How does a Grand Challenge Become Displaced? Explaining the Duality of Field Mobilization

“Grand challenges” are complex problems with far-reaching societal implications that lack a clear solution. To make progress, diverse communities often coalesce around an ambitious field goal. However, many field initiatives fall short of their initial objectives. When fields mobilize for a grand challenge, what inhibits them from realizing their intended ambitions? This is a critical question not only for grand challenges, but also for institutional theory, which tends to focus on field mobilization rather than on how goals are pursued over time. Field scholars often assume stable participants with goals that easily translate into actions, but fields are dynamic and unlikely to comply with these assumptions. With a longitudinal, multimethod study of the nanotechnology field, we examined how five communities mobilized and pursued the grand challenge of creating molecular manufacturing from 1986 to 2005. We identify a key duality of mobilization: the very strategies employed to successfully mobilize divers.
Major depressive episode among young adults: CIDI-SF versus SCAN consensus diagnoses

Background. We aimed to evaluate the diagnostic accuracy of a highly structured diagnostic interview in relation to a semi-structured diagnostic procedure. We compared the World Health Organization Composite International Diagnostic Interview Short Form (CIDI-SF) in diagnosing major depressive episode (MDE) to consensus diagnoses based on the SCAN interview (Schedules for Clinical Assessment in Neuropsychiatry). Method. Subjects comprised a follow-up sample of 239 20–24-year-old former high-school students who were administered the SCAN and immediately thereafter the CIDI-SF. Concordance was estimated for 12-month MDE, using different cut-points of the CIDI-SF and for any affective disorders. Results. Correspondence between instruments was moderate for MDE (κ = 0.43, sensitivity 0.71, specificity 0.82), but better for any affective disorder (κ = 0.60, sensitivity 0.70, specificity 0.90). Most false negatives suffered from their depression as much as those correctly identified by the CIDI-SF. False negativity was mainly due to not endorsing the stem questions of the CIDI-SF. Of the false positives almost half had an affective disorder other than MDE. Conclusions. The CIDI-SF seems to function best in identifying a broader category of affective disorders. It could be useful in large-scale community surveys where more extensive psychiatric interviews are not feasible.
Transcription of True Late (γ2) Cytomegalovirus Genes Requires UL92 Function That Is Conserved among Beta- and Gammaherpesviruses

ABSTRACT Human cytomegalovirus-encoded UL92 plays an essential role in viral replication that has not been resolved. We show here that this gene controls the accumulation of true late (γ2) viral transcripts, a property shared with several other recently evaluated genes (UL79, UL87, UL91, and UL95) conserved among beta- and gammaherpesviruses. When the UL92 mutant virus was evaluated, function was fully complemented by either the natural protein or the homologous Rh127 protein from rhesus cytomegalovirus. N-terminal epitope-tagged UL92 protein is functional, follows complex early-late expression kinetics, and localizes in the nucleus within viral replication compartments. UL92 severely impacts the late (72-h postinfection) expression of nine genes encoding virion proteins (UL32, UL55, UL73, UL75, UL80, UL86, UL99, and UL115), as well as UL91 and itself, but does not influence the levels of UL44, UL82, or UL83 accumulation. Although viral DNA is made at normal levels, viral capsid accumulation in the nucleus is severely compromised in UL92 mutant virus-infected cells, and mature virions are not observed in the cytoplasm. Taken together, UL92 is a key regulator of late viral gene expression, apparently functioning with four other beta- or gammaherpesvirus gene products in a pattern that appears reminiscent of gene regulation in T4 DNA bacteriophage.

Funding challenges of Latin American women start-up founders in the technology industry

Purpose Women in entrepreneurship can have a significant impact on economic and social development globally and particularly in developing countries. But the challenges entrepreneurial women face are unique and multiple, pressing the need for research and policies to maximize impact. The purpose of this paper is to analyze the challenges women start-up founders face to secure funding in the technology industry. The tech industry was selected because it is a non-traditional industry for women with high potential for role models to bridge an existing gap in information on women start-up founders to secure capital financing to attain business sustainability. It covers venture capital investors’ role, Latin American cultural reasons, and gender. Design/methodology/approach This study is based on an inductive, qualitative approach and in-depth interviews with 20 women entrepreneurs and start-up founders from Latin American countries who received support from the Chilean Government sponsored accelerator “Start-Up Chile. ” Findings The analysis uncovered ten aspects that impact entrepreneurial women founders’ access to capital in three categories: capital needs, networks, and individual characteristics. Originality/value This study identifies factors that affect women entrepreneurs in raising capital and in facing the following challenges: first, working in a non-traditional field for women as it is the technology industry, and second assuming a leadership role as start-up founders. The results offer recommendation with potential to drive public policies in Latin America, which may be scalable to other developing and also to developed countries where market systems prevail. The findings show that women entrepreneurs, but also men, seeking start-up financing and alternatives are a viable source of employment and economic sustainability to mitigate the effects of increasing levels of unemployment worldwide.
