Why do Users Kill HPC Jobs?

Given the cost of HPC clusters, making best use of them is crucial to improve infrastructure ROI. Likewise, reducing failed HPC jobs and related waste in terms of user wait times is crucial to improve HPC user productivity (aka human ROI). While most efforts (e.g., debugging HPC programs) explore technical aspects to improve ROI of HPC clusters, we hypothesize non-technical (human) aspects are worth exploring to make non-trivial ROI gains; specifically, understanding non-technical aspects and how they contribute to the failure of HPC jobs. In this regard, we conducted a case study in the context of Beocat cluster at Kansas State University. The purpose of the study was to learn the reasons why users terminate jobs and to quantify wasted computations in such jobs in terms of system utilization and user wait time. The data from the case study helped identify interesting and actionable reasons why users terminate HPC jobs. It also helped confirm that user terminated jobs may be associated with non-trivial amount of wasted computation, which if reduced can help improve the ROI of HPC clusters.
Effects of high-fat diet and AMP-activated protein kinase modulation on the regulation of whole-body lipid metabolism

Metabolic flexibility, the capacity to adapt to fuel availability for energy production, is crucial for maintaining whole-body energy homeostasis. An inability to adequately promote FA utilization is associated with lipid accumulation in peripheral tissues and contributes to the development of insulin resistance. In vivo assays to quantify whole-body lipid oxidation in mouse models of insulin resistance are lacking. We describe a method for assessing whole-body FA oxidation in vivo, as well as tissue-specific lipid uptake in conscious mice. The method relies on intravenous administration of [9,10-3H(N)]palmitic acid combined with a non-β-oxidizable palmitate analog, [1-14C]2-bromopalmitic acid. Pretreatment with etomoxir, a CPT1 inhibitor that prevents the shuttling of FAs into mitochondria, markedly reduced the appearance of the β-oxidation product 3H2O in circulation and reduced lipid uptake by oxidative tissues including heart and soleus muscle. Whole-body fatty oxidation was unaltered between chow- or high-fat-fed WT and transgenic mice expressing a mutant form of the AMPK γ3 subunit (AMPKγ3R225Q) in skeletal muscle. High-fat feeding increased lipid oxidation in WT and AMPKγ3R225Q transgenic mice. In conclusion, this technique allows for the assessment of the effect of pharmaceutical agents, as well as gene mutations, on whole-body FA oxidation in mice.
CD146 interacts with galectin‐3 to mediate endothelial cell migration

Here, we investigated the role of the cell membrane protein CD146 in galectin‐3‐mediated endothelial cell migration at the molecular level. Our results show that knocking down CD146 significantly attenuates galectin‐3‐mediated cell migration. Pull‐down assays, gel filtration, and biolayer interferometry further demonstrate that galectin‐3 binds to the CD146 ectodomain (eFL) with a KD of ~1.1 μm. To identify the galectin‐3‐binding site, we used mass spectrometry to show that CD146 eFL has four N‐glycosites, with PNGase F treatment indicating that N‐glycans define the binding epitope. Galectin‐3 likely interacts with Domain 5 on CD146 eFL, because it contains poly‐N‐acetyllactosamine sites, and deletion of this domain significantly reduces binding. Overall, our findings provide a better understanding of how galectin‐3 interacts with cell membrane receptors to mediate endothelial cell migration.
CH3 NH3 PbI3 and HC(NH2 )2 PbI3 Powders Synthesized from Low-Grade PbI2 : Single Precursor for High-Efficiency Perovskite Solar Cells.

High-efficiency perovskite solar cells are generally fabricated by using highly pure (>99.99 %) PbI2 mixed with an organic iodide in polar aprotic solvents. However, the use of such an expensive chemical may impede progress toward large-scale industrial applications. Here, we report on the synthesis of perovskite powders by using inexpensive low-grade (99 %) PbI2 and on the photovoltaic performance of perovskite solar cells prepared from a powder-based single precursor. Pure APbI3 [A=methylammonium (MA) or formamidinium (FA)] perovskite powders were synthesized by treating low-grade PbI2 with MAI or FAI in acetonitrile at ambient temperature. The structural phase purity was confirmed by X-ray diffraction. The solar cell with a MAPbI3 film prepared from the synthesized perovskite powder demonstrated a power conversion efficiency (PCE) of 17.14 %, which is higher than the PCE of MAPbI3 films prepared by using both MAI and PbI2 as precursors (PCE=13.09 % for 99 % pure PbI2 and PCE=16.39 % for 99.9985 % pure PbI2 ). The synthesized powder showed better absorption and photoluminescence, which were responsible for the better photovoltaic performance. For the FAPbI3 powder, a solution with a yellow non-perovskite δ-FAPbI3 powder synthesized at room temperature was found to lead to a black perovskite film, whereas a solution with the black perovskite α-FAPbI3 powder synthesized at 150 °C was not transformed into a black perovskite film. The α↔δ transition between the powder and film was assumed to correlate with the difference in the iodoplumbates in the powder-dissolved solution. An average PCE of 17.21 % along with a smaller hysteresis [ΔPCE=PCEreverse -PCEforward )=1.53 %] was demonstrated from the perovskite solar cell prepared by using δ-FAPbI3 powder; this PCE is higher than the average PCE of 17.05 % with a larger hysteresis (ΔPCE=2.71 %) for a device based on a conventional precursor solution dissolving MAI with high-purity PbI2 . The smaller hysteresis was indicative of fewer defects in the resulting FAPbI3 film prepared by using the δ-FAPbI3 powder.
Psychometric Properties of OPMH-40, a Survey for the Evaluation of the Occupational Positive Mental Health

The aim of this study was to determine the psychometric properties of a measurement instrument design for the evaluation of the occupational positive mental health. Based on the positive psychology, humanism, salutogenesis and ecological model, we developed a 40 items survey with a five-point Liker response option. A sample of 740 workers of different occupations answered the survey, taking an average of 15 minutes. The data analysis included exploratory factor analysis for the determination of factorial validity and Cronbach’s Alpha coefficient for reliability. The results indicated a four-factor structure that explains 43.55% of the total variance and a Cronbach’s Alpha of . 923 for the whole instrument. We conclude that the SMPO-40 is a valid and reliable measurement instrument for the evaluation of the occupational positive mental health.
A Specific Multi-Approach Intervention for Adhesive Capsulitis: A Case Report

Background: Adhesive capsulitis is a common cause of shoulder pain and disability. A variety of therapeutic interventions, such as physical therapy treatment, mobilization, exercise, soft tissue therapy among others are available for restoring motion and diminishing pain in patients with adhesive capsulitis. Nevertheless, the evidence for the combined usage and effectiveness of some interventions is lacking Objective: To describe an evaluation and conservative treatment approach consisting of a specific active-exercise program, manual therapy and the aid of electro therapy for an individual with a primary adhesive capsulitis. Design: A case report a case of primary adhesive capsulitis in a fifty-four-year-old woman is presented to illustrate clinical presentation, diagnosis and conservative management methods. The patient was treated 2 times over a 4-month period. Active and passive range of motion of abduction, flexion and external rotation were assessed in the beginning, and after 4, 13 and 16 weeks. Intervention included low level laser therapy with sustained pressure, ultrasound, manual therapy techniques and stretching and strengthening exercises. Results: After the 16 weeks-period treatment the patient’s shoulder range of motion was full and pain free. Conclusions: The multi-approach intervention revealed effective in treating primary adhesive capsulitis in a fifty-four-year-old woman.
Color Vision Based High Dynamic Range Images Rendering

The algorithms, mapping the high dynamic range images to the low dynamic range images, have been described in many literatures. Especially, tone mapping operators are the typical algorithms which are designed to produce visibility and the overall impression of brightness, contrast and color of HDR images onto relative LDR displays and printers. But the results of these algorithms did not match these of the psychophysical experiments based on Human Visual System. The mismatches were specially presented on color, so Kuang al. et proposed a display rendering algorithm based on color appearance models to improve the color rendering. In our testing experiments of the algorithm of Kuang al. et. , it found that the colors of the rendering images shifted to the blue and color leakage also happened. In this paper, we proposed a HDR rendering algorithm based on color vision of the human to resolve the issues of the algorithm of Kuang al. et.
Acceleration of multivariate analysis techniques in TMVA using GPUs

A feasibility study into the acceleration of multivariate analysis techniques using Graphics Processing Units (GPUs) will be presented. The MLP-based Artificial Neural Network method contained in the TMVA framework has been chosen as a focus for investigation. It was found that the network training time on a GPU was lower than for CPU execution as the complexity of the network was increased. In addition, multiple neural networks can be trained simultaneously on a GPU within the same time taken for single network training on a CPU. This could be potentially leveraged to provide a qualitative performance gain in data classification.
Evaluation of projection‐ and dual‐energy‐based methods for metal artifact reduction in CT using a phantom study

Abstract Objectives Both projection and dual‐energy (DE)‐based methods have been used for metal artifact reduction (MAR) in CT. The two methods can also be combined. The purpose of this work was to evaluate these three MAR methods using phantom experiments for five types of metal implants. Materials and Methods Five phantoms representing spine, dental, hip, shoulder, and knee were constructed with metal implants. These phantoms were scanned using both single‐energy (SE) and DE protocols with matched radiation output. The SE data were processed using a projection‐based MAR (iMAR, Siemens) algorithm, while the DE data were processed to generate virtual monochromatic images at high keV (Mono+, Siemens). In addition, the DE images after iMAR were used to generate Mono+ images (DE iMAR Mono+). Artifacts were quantitatively evaluated using CT numbers at different regions of interest. Iodine contrast‐to‐noise ratio (CNR) was evaluated in the spine phantom. Three musculoskeletal radiologists and two neuro‐radiologists independently ranked the artifact reduction. Results The DE Mono+ at high keV resulted in reduced artifacts but also lower iodine CNR. The iMAR method alone caused missing tissue artifacts in dental phantom. DE iMAR Mono+ caused wrong CT numbers in close proximity to the metal prostheses in knee and hip phantoms. All musculoskeletal radiologists ranked SE iMAR > DE iMAR Mono+ > DE Mono+ for knee and hip, while DE iMAR Mono+ > SE iMAR > DE Mono+ for shoulder. Both neuro‐radiologists ranked DE iMAR Mono+ > DE Mono+ > SE iMAR for spine and DE Mono+ > DE iMAR Mono+ > SE iMAR for dental. Conclusions The SE iMAR was the best choice for the hip and knee prostheses, while DE Mono+ at high keV was best for dental implants and DE iMAR Mono+ was best for spine and shoulder prostheses. Artifacts were also introduced by MAR algorithms.
Glycated haemoglobin A1c (HbA1c) for detection of diabetes mellitus and impaired fasting glucose in Malawi: a diagnostic accuracy study

Objectives To examine the accuracy of glycated haemoglobin A1c (HbA1c) in detecting type 2 diabetes and impaired fasting glucose among adults living in Malawi. Design A diagnostic validation study of HbA1c. Fasting plasma glucose (FPG) ≥7.0 mmol/L was the reference standard for type 2 diabetes, and FPG between 6.1 and 6.9 mmol/L as impaired fasting glucose. Participants 3645 adults (of whom 63% were women) recruited from two demographic surveillance study sites in urban and rural Malawi. This analysis excluded those who had a previous diagnosis of diabetes or had history of taking diabetes medication. Results HbA1c demonstrated excellent validity to detect FPG-defined diabetes, with an area under the receiver operating characteristic (AUROC) curve of 0.92 (95% CI 0.90 to 0.94). At HbA1c ≥6.5% (140 mg/dL), sensitivity was 78.7% and specificity was 94.0%. Subgroup AUROCs ranged from 0.86 for participants with anaemia to 0.94 for participants in urban Malawi. There were clinical and metabolic differences between participants with true diabetes versus false positives when HbA1c was ≥6.5% (140 mg/dL). Conclusions The findings from this study provide justification to use HbA1c to detect type 2 diabetes. As HbA1c testing is substantially less burdensome to patients than either FPG testing or oral glucose tolerance testing, it represents a useful option for expanding access to diabetes care in sub-Saharan Africa.
Acoustic direction finding using a pressure sensor and a uniaxial particle velocity sensor

One isotropic pressure sensor and one uniaxial particle velocity sensor is used in order to estimate the azimuth-elevation angle of arrival of a source impinging from the far field. This work introduces new estimation formulas in closed forms applicable to estimators based on an eigen-decomposition of the data covariance matrix. The validity region for unambiguous estimation is also identified, and the corresponding Cramer-Rao bound is derived as well.
What Do Short-Term and Long-Term Relationships Look Like? Building the Relationship Coordination and Strategic Timing (ReCAST) Model

Close relationships research has examined committed couples (e.g., dating relationships, marriages) using intensive methods that plot relationship development over time. But a substantial proportion of people’s real-life sexual experiences take place (a) before committed relationships become “official” and (b) in short-term relationships; methods that document the time course of relationships have rarely been applied to these contexts. We adapted a classic relationship trajectory-plotting technique to generate the first empirical comparisons between the features of people’s real-life short-term and long-term relationships across their entire timespan. Five studies compared long-term and short-term relationships in terms of the timing of relationship milestones (e.g., flirting, first sexual intercourse) and the occurrence/intensity of important relationship experiences (e.g., romantic interest, strong sexual desire, attachment). As romantic interest was rising and partners were becoming acquainted, long-term and short-term relationships were indistinguishable. Eventually, romantic interest in short-term relationships plateaued and declined while romantic interest in long-term relationships continued to rise, ultimately reaching a higher peak. As relationships progressed, participants evidenced more features characteristic of the attachment-behavioral system (e.g., attachment, caregiving) in long-term than short-term relationships but similar levels of other features (e.g., sexual desire, self-promotion, intrasexual competition). These data inform a new synthesis of close relationships and evolutionary psychological perspectives called the Relationship Coordination and Strategic Timing (ReCAST) model. ReCAST depicts short-term and long-term relationships as partially overlapping trajectories (rather than relationships initiated with distinct strategies) that differ in their progression along a normative relationship development sequence.
Genetic Diversity of Ascaris in China Assessed Using Simple Sequence Repeat Markers

The giant roundworm Ascaris infects pigs and people worldwide and causes serious diseases. The taxonomic relationship between Ascaris suum and Ascaris lumbricoides is still unclear. The purpose of the present study was to investigate the genetic diversity and population genetic structure of 258 Ascaris specimens from humans and pigs from 6 sympatric regions in Ascaris-endemic regions of China using existing simple sequence repeat data. The microsatellite markers showed a high level of allelic richness and genetic diversity in the samples. Each of the populations demonstrated excess homozygosity (Ho0). According to a genetic differentiation index (Fst=0.0593), there was a high-level of gene flow in the Ascaris populations. A hierarchical analysis on molecular variance revealed remarkably high levels of variation within the populations. Moreover, a population structure analysis indicated that Ascaris populations fell into 3 main genetic clusters, interpreted as A. suum, A. lumbricoides, and a hybrid of the species. We speculated that humans can be infected with A. lumbricoides, A. suum, and the hybrid, but pigs were mainly infected with A. suum. This study provided new information on the genetic diversity and population structure of Ascaris from human and pigs in China, which can be used for designing Ascaris control strategies. It can also be beneficial to understand the introgression of host affiliation.
HLA-F on HLA-Null 721.221 Cells Activates Primary NK Cells Expressing the Activating Killer Ig-like Receptor KIR3DS1

NK cells elicit important responses against transformed and virally infected cells. Carriage of the gene encoding the activating killer Ig-like receptor KIR3DS1 is associated with slower time to AIDS and protection from HIV infection. Recently, open conformers of the nonclassical MHC class Ib Ag HLA-F were identified as KIR3DS1 ligands. In this study, we investigated whether the interaction of KIR3DS1 on primary NK cells with HLA-F on the HLA-null cell line 721.221 (221) stimulated KIR3DS1+ NK cells. We used a panel of Abs to detect KIR3DS1+CD56dim NK cells that coexpressed the inhibitory NK cell receptors KIR2DL1/L2/L3, 3DL2, NKG2A, and ILT2; the activating NK cell receptors KIR2DS1/S2/S3/S5; and CCL4, IFN-γ, and CD107a functions. We showed that both untreated and acid-pulsed 221 cells induced a similar frequency of KIR3DS1+ cells to secrete CCL4/IFN-γ and express CD107a with a similar intensity. A higher percentage of KIR3DS1+ than KIR3DS1− NK cells responded to 221 cells when either inclusive or exclusive (i.e., coexpressing none of the other inhibitory NK cell receptors and activating NK cell receptors detected by the Ab panel) gating strategies were employed to identify these NK cell populations. Blocking the interaction of HLA-F on 221 cells with KIR3DS1-Fc chimeric protein or anti–HLA-F Abs on exclusively gated KIR3DS1+ cells reduced the frequency of functional cells compared with that of unblocked conditions for stimulated KIR3DS1+ NK cells. Thus, ligation of KIR3DS1 activates primary NK cells for several antiviral functions.
An empirical approach for fake user detection in location-based social networks

Location-based social networks are becoming a unique platform for understanding user behaviors and providing pervasive services in intelligent environments. However, fake users or accounts can undermine user analytics and lower the value of the applications and services intended for real users. Mining a large Foursquare dataset and related Twitter accounts, we tested different user features with the goal of classifying fake users. Experiments demonstrate an accuracy over 95% in detecting fake users. Filtering out these fake users reduces the error rate of a location-based activity predictor by a 4.4% and avoids wasting 35% of coupons or promotion codes delivery if applied to a recommender system.
Security Based Image Processing using Reversible Data Hiding Method

: Encryption is a process which uses a finite set of instruction called an algorithm to convert original message, known as plaintext, into cipher text, its encrypted form. To secure the exchange of important multimedia data over the internet, steganography techniques are extensively used in recent years. By using such techniques the sensitive data is hidden in covert object making its existence imperceptible to the intruder during transmission. In our project we mainly use system Reversible-Data-Hiding method for embedding and extraction of secret image. It depends on the histogram-shifting. We basically have two phase they are embedding phase and extracting phase.
Myosin-1c promotes E-cadherin tension and force-dependent recruitment of α-actinin to the epithelial cell junction

ABSTRACT Actomyosin II contractility in epithelial cell plays an essential role in tension-dependent adhesion strengthening. One key unsettling question is how cellular contraction transmits force to the nascent cell–cell adhesion when there is no stable attachment between the nascent adhesion complex and actin filament. Here, we show that myosin-1c is localized to the lateral membrane of polarized epithelial cells and facilitates the coupling between actin and cell–cell adhesion. Knockdown of myosin-1c compromised the integrity of the lateral membrane, reduced the generation of tension at E-cadherin, decreased the strength of cell–cell cohesion in an epithelial cell monolayer and prevented force-dependent recruitment of junctional α-actinin. Application of exogenous force to cell–cell adhesions in a myosin-1c-knockdown cell monolayer fully rescued the localization defect of α-actinin, indicating that junction mechanoregulation remains intact in myosin-1c-depleted cells. Our study identifies a role of myosin-1c in force transmission at the lateral cell–cell interface and underscores a non-junctional contribution to tension-dependent junction regulation. Highlighted Article: Myosin-1c is a regulator of intercellular tension that can promote tension generation from the extracellular domain of E-cadherin, propagating actomyosin-generated force to intercellular junctions.
An experimental test on cumulative prospect theory

Cumulative Prospect Theory is a revised version of Prospect Theory.The former adopted CE research norm to study American subjects and got such conclusions:(i) People's risk attitudes have four-fold pattern;(ii) Risk aversion for gain is more pronounced than risk seeking for loss when the probabilities are moderate or high;(iii) The indexes of value function and weight function are less than 1.This research adopted the same research norm to investigate Chinese subjects and found:(i) can be applied to Chinese subjects;(iii) cannot always be applied to Chinese subjects;(ii) can never applied to Chinese subjects.
