Robustness in ferromagnetic phase stability, half‐metallic behavior and transport properties of cobalt‐based full‐Heuslers compounds: A first principles approach
Authors: Sofi Shakeel Ahmad , Gupta Dinesh C. 
Published: November 2020

AbstractHeusler alloys fill up the demanding gaps and becomes a point of prestige due to their interesting multi‐dimensional and remarkable applications in future technologies like spintronics and thermoelectrics. Self‐consistent ab‐initio calculations with highly precise spin‐polarized density functional theory associated with Boltzmann transport scheme have been perform to investigate the structural stability, mechanical, magneto‐electronic, thermo‐physical and thermoelectric transport properties of Co2VX (X = Sn, Sb) Heuslers. The equilibrium lattice parameters at the cost of structural optimizations are observed to agree with the available experimental data. The occurrence of perfect band occupation and interpretation of density of states through the modified version of Becke Johnson scheme delivers more precise and accurate results rather than GGA and GGA + U, possessing an indirect band gap of 1.12 eV and 1.34 eV in spin down channel of Co2VX (X = Sn, Sb) Heuslers respectively. Robustness of various elastic constants and its other associated mechanical constituents against external forces is checked to define the stability of these alloys. The transport parameters like Seebeck coefficient, electrical and thermal conductivity, power factor and zT have been put together to express their thermoelectric response. Conservative estimates of Seebeck coefficient and zT demonstrate its extending application stand in thermoelectric energy harvesting technologies. Furthermore complete and precise description of thermo‐physical behavior of the vital quantities like Debye temperature, thermal expansion, Grüneisen parameter and specific heat were examined to check its thermo‐dynamical stability against temperature and pressure variation.

Published: November 2020

AbstractBeerkan infiltration experiments with three water pouring heights (low, L = 3 cm; intermediate, M = 100 cm; high, H = 200 cm) were performed on both a no‐tilled (NT) and a conventionally tilled (CT) bare loam soil to determine the surface soil hydraulic properties by the BEST‐steady algorithm. Saturated soil hydraulic conductivity, Ks, significantly and monotonically decreased from the L to the H runs (from 236 to 37 mm h‒1) and lower Ks values were detected under CT (163–23 mm h‒1) than NT (346–51 mm h‒1) for each water pouring height. For both soil management practices, the gravitational potential energy, Ep, of the water used for the infiltration runs, explained most of the variance in the mean Ks values. According to the fitted relationships, an increase of Ep from 50 to 3,327 J m‒2 determined a Ks decrease by a factor of 9.5 in the CT soil and 6.3 in the NT soil. The CT soil was 2.1 and 3.3 times less conductive than the NT soil with the lowest and the highest energy, respectively. The water retention scale parameter, hg, only varied between non‐perturbing (L) and perturbing (M, H) runs because |hg| increased from 55 to 93–100 mm. Therefore, water impact can greatly influence hydrodynamic properties of the upper soil layer regardless of the management practice. The tested infiltration methodology looks promising to mimic effects of relatively high energy rainfall events and to determine the hydraulic properties of the exposed soil layer under different management practices.
Spillover and dynamic effects of energy transition and economic growth on carbon dioxide emissions for the European Union: A dynamic spatial panel model
Authors: Ren Xiaohang , Cheng Cheng , Wang Zhen , Yan Cheng 
Published: November 2020

AbstractThis paper introduces “spatial effects” and “dynamic effects” to investigate the influences of economic growth and energy transition on cross‐country CO2 emissions movements within the European Union (EU). We apply the fixed‐effects dynamic spatial Durbin error model to empirically gauge the magnitude of the spatial impacts and dynamic impacts for a sample of 26 EU countries throughout 1990–2015. By analyzing the empirical results, we conclude that: (1) Compared with dynamic spatial Durbin error model, the traditional dynamic panel model over‐estimates the parameters because traditional regression methods only capture the direct impacts, and neglect the indirect impacts. (2) A significant positive spatial spillover of CO2 emissions from neighboring countries to the local country is recognized, justifying the use of our spatial model. (3) Economic growth has positive impacts on CO2 emissions, while the spatial effects of economic growth exert negative impacts. Moreover, the total effects of economic growth are positive in both short‐term and long‐term. (4) Although the spatial effects of renewable energy are not significant, renewable energy has negative influences on CO2 emissions. (5) The impacts and spatial effects of natural gas are positive; therefore, its total effects are positive in both short‐run and long‐run. Based on our finding, we provide several policy recommendations, such as the emphasize of cooperation with CO2 reduction policies, the promotion of green economy and renewable energy, and the substitution of natural gas in the future.
The relative importance of targets' neuroticism facets in relation to their perceptions of workplace mistreatment
Authors: McCord Mallory A. 
Published: November 2020

AbstractDespite evidence that indicates neuroticism is the strongest Five Factor Model personality correlate of perceived workplace mistreatment, there is a paucity of research on the relationship between neuroticism facets and mistreatment, particularly, the relative importance of these facets. Clarity in this regard could aid our understanding as to why neuroticism is related to mistreatment and thus guide theory building, in addition to increasing the utility of personality measures and organizational interventions. Data from a sample of 307 employees were used to conduct an exploratory relative weights analysis of the six neuroticism facets on two forms of mistreatment. Results indicated that the facets of depression, anxiety and anger consistently explained significant proportions of the variance in both group‐based and non‐group‐based mistreatment whereas self‐consciousness, immoderation and vulnerability did not. Implications, limitations and directions for future research are discussed.

Published: November 2020

AbstractCovalent organic frameworks (COFs) are promising candidates for electrocatalytic reduction of carbon dioxide into valuable chemicals due to their porous crystalline structures and tunable single active sites, but the low conductivity leads to unmet current densities for commercial application. The challenge is to create conductive COFs for highly efficient electrocatalysis of carbon dioxide reduction reaction (CO2RR). Herein, a porphyrin‐based COF containing donor–acceptor (D–A) heterojunctions, termed TT‐Por(Co)‐COF, is constructed from thieno[3,2‐b]thiophene‐2,5‐dicarbaldehyde (TT) and 5,10,15,20‐tetrakis(4‐aminophenyl)‐porphinatocobalt (Co‐TAPP) via imine condensation reaction. Compared with COF‐366‐Co without TT, TT‐Por(Co)‐COF displays enhanced CO2RR performance to produce CO due to its favorable charge transfer capability from the electron donor TT moieties to the acceptor Co‐porphyrin ring active center. The combination of strong charge transfer properties and enormous amount of accessible active sites in the 2D TT‐Por(Co)‐COF nanosheets results in good catalytic performance with a high Faradaic efficiency of CO (91.4%,−0.6 V vs reversible hydrogen electrode (RHE) and larger partial current density of 7.28 mA cm−2at−0.7 V versus RHE in aqueous solution. The results demonstrate that integration of D–A heterojunctions in COF can facilitate the intramolecular electron transfer, and generate high current densities for CO2RR.
SCOZ: A system‐wide causal profiler for multicore systems

Published: November 2020

AbstractThe increased complexity of hardware and software makes it difficult to analyze programs with conventional profilers. The causal profiling technique is introduced to solve the problem of conventional profilers. The causal profiling technique finds the bottleneck of the program and shows the effect of optimizing it. COZ, the newest causal profiler, exploits a technique called virtual speedup to perform causal profiling without actually optimizing program codes. However, it can only profile multithreaded applications, and cannot profile multiprogram applications and operating system (OS) kernel codes, thereby limiting the use of causal profiling. This article introduces SCOZ, a system‐wide causal profiler that addresses these limitations. The proposed profiler changes the target of virtual speedup from threads to CPU cores, thereby expanding the profiling coverage to diverse applications as well as OS kernel codes. To verify our profiler, we profiled multithreaded and OS kernel‐intensive applications. For multithread applications, our profiler shows identical results to what COZ provides. For the OS kernel‐intensive applications, our profiler identifies identical bottlenecks that previous OS scalability studies have pinpointed. Finally, we verified the profiling capability of the proposed profiler by profiling and optimizing multiprocess applications in the NAS parallel benchmark suite.

Published: November 2020

AbstractThe present study evaluates the regenerative activity of a polysaccharide fraction from yerba mate (Ilex paraguariensisSt. Hil.) using planarian (Girardia tigrina) as a model. At 10 mg L–1, the polysaccharide fraction improves the regeneration of the head, pharynx, and tail ofG. tigrina. At the end of experiment, at 10 mg L–1, the planarians obtained are 22–72% higher than the control group. The planarian fragments exposed to the highest concentration used, i.e., (60 mg mL–1), show signs of toxicity, producing death of some organisms. Thus, the polysaccharide fraction presents a great potential for improving the regeneration of planarian segments, suggesting its potential use in tissue regeneration.
Membrane distillation of concentrated blackwater: Effect of temperature, solids concentration and membrane pore size

Published: November 2020

AbstractThis study has elucidated the mechanisms governing water recovery from blackwater using membrane distillation, and has clarified the role of the organic particle fraction on membrane performance. Whilst fecal pathogen growth was initially observed at lower temperatures, pathogen inactivation was demonstrated over time, due to urea hydrolysis which liberated ammonia in excess of its toxic threshold. During the growth phase, membrane pore size <0.45 µm was sufficient to achieve high log reduction values for Escherichia coli, due to size exclusion complimented by the liquid–vapor interface which enhances selective transport for water. Higher feed temperatures benefitted rejection by promoting thermal inactivation and suppressing urea hydrolysis. Whilst the mechanism is not yet clear, suppression of hydrolysis reduced bicarbonate formation kinetics stabilizing the ammonia‐ammonium equilibrium which improved ammonium rejection. Blackwater particle concentration was studied by increasing fecal content. Particle fouling improved selectivity for coarse pore membranes but increased mass transfer resistance which reduced flux. Particle fouling induced wetting as noted by an eventual breakthrough of feed into the permeate. We propose that by incorporating upstream solid–liquid separation for particle separation to limit wetting and mass transfer resistance, membrane distillation can be a reliable solution for the recovery of high‐quality permeate from blackwater.Practitioner points

Membrane distillation demonstrated for concentrated blackwater.

Multiple factors provide robust pathogen separation (pore size, vapor–liquid interface, temperature, free‐ammonia).

Excellent water quality produced for feed 40 times more concentrated than wastewater.

Removing particle fraction will improve separation robustness and operating longevity.
The Regge limit of AdS3 holographic correlators
Authors: Giusto Stefano , Hughes Marcel R.R. , Russo Rodolfo 
Published: November 2020

Abstract
We study the Regge limit of 4-point AdS3× S3 correlators in the tree-level supergravity approximation and provide various explicit checks of the relation between the eikonal phase derived in the bulk picture and the anomalous dimensions of certain double-trace operators. We consider both correlators involving all light operators and HHLL correlators with two light and two heavy multi-particle states. These heavy operators have a conformal dimension proportional to the central charge and are pure states of the theory, dual to asymptotically AdS3× S3 regular geometries. Deviation from AdS3× S3 is parametrised by a scale μ and is related to the conformal dimension of the dual heavy operator. In the HHLL case, we work at leading order in μ and derive the CFT data relevant to the bootstrap relations in the Regge limit. Specifically, we show that the minimal solution to these equations relevant for the conical defect geometries is different to the solution implied by the microstate geometries dual to pure states.

ZusammenfassungIm Herbst und Winter 2020/2021 wird der Umgang mit Fällen einer vermuteten oder nachgewiesenen SARS-CoV-2-Infektion die bereits durch die bekannten saisonalen Virusinfektionen (u. a. RSV [respiratory syncytial virus] oder Influenzavirus) oft über die Grenzen hinaus belasteten Kinder- und Jugendkliniken hinsichtlich Isolierung oder Kohortierung vor erhebliche zusätzliche Herausforderungen stellen. Dies wird zu Engpässen in der Versorgung nicht nur der akut kranken Kinder, sondern mutmaßlich auch vieler anderer Patientenpopulationen führen. Daher müssen pragmatische, aber gleichwohl krankenhaushygienisch vertretbare Lösungsansätze vorbereitet werden. Die hier erarbeitete Stellungnahme soll den Kinderkliniken Hilfestellung für die Entscheidungsfindung geben. Diese orientiert sich im Wesentlichen an der Inzidenz von SARS-CoV‑2 im Kreis bzw. im Einzugsgebiet. Ist die Inzidenz niedrig (kumulative Anzahl der Neuinfektionen in den letzten 7 Tagen: <25/100.000) oder mittelhoch (25–50/100.000), erfolgt die Diagnostik unter Standardhygienebedingungen und die Kohortierung je nach Erreger oder Symptomatik. Ist die Inzidenz der Neuerkrankungen in der Region hoch (>50/100.000), erfolgt die Diagnostik unter entsprechenden, vom RKI vorgegebenen Sicherheitsvorkehrungen mit nachfolgender Isolierung bzw. Kohortierung der Patienten. Die vorgeschlagenen Grenzwerte können nach Maßgabe der Gesundheitsbehörde variieren. Bei überschrittener Aufnahmekapazität oder Versorgungsengpässen ist im Einzelfall die akute Notwendigkeit einer medizinischen Notfallversorgung prioritär, was vorübergehend ein weniger striktes Isolierungsregime erfordern kann.

AbstractA liquid chromatography tandem mass spectrometry method for the analysis of ten kinase inhibitors (afatinib, axitinib, bosutinib, cabozantinib, dabrafenib, lenvatinib, nilotinib, osimertinib, ruxolitinib, and trametinib) in human serum and plasma for the application in daily clinical routine has been developed and validated according to the US Food and Drug Administration and European Medicines Agency validation guidelines for bioanalytical methods. After protein precipitation of plasma samples with acetonitrile, chromatographic separation was performed at ambient temperature using a Waters XBridge® Phenyl 3.5 μm (2.1 × 50 mm) column. The mobile phases consisted of water-methanol (9:1, v/v) with 10 mM ammonium bicarbonate as phase A and methanol-water (9:1, v/v) with 10 mM ammonium bicarbonate as phase B. Gradient elution was applied at a flow rate of 400 μL/min. Analytes were detected and quantified using multiple reaction monitoring in electrospray ionization positive mode. Stable isotopically labeled compounds of each kinase inhibitor were used as internal standards. The acquisition time was 7.0 min per run. All analytes and internal standards eluted within 3.0 min. The calibration curves were linear over the range of 2–500 ng/mL for afatinib, axitinib, bosutinib, lenvatinib, ruxolitinib, and trametinib, and 6–1500 ng/mL for cabozantinib, dabrafenib, nilotinib, and osimertinib (coefficients of correlation ≥ 0.99). Validation assays for accuracy and precision, matrix effect, recovery, carryover, and stability were appropriate according to regulatory agencies. The rapid and sensitive assay ensures high throughput and was successfully applied to monitor concentrations of kinase inhibitors in patients.

Abstract
Background
The aim of this proof-of-concept study was to show that the liver segmental volume and attenuation ratio (LSVAR) improves the detection of significant liver fibrosis on portal venous CT scans by adding the liver vein to cava attenuation (LVCA) to the liver segmental volume ratio (LSVR).

Material and methods
Patients who underwent portal venous phase abdominal CT scans and MR elastography (reference standard) within 3 months between 02/2016 and 05/2017 were included. The LSVAR was calculated on portal venous CT scans as LSVR*LVCA, while the LSVR represented the volume ratio between Couinaud segments I-III and IV-VIII, and the LVCA represented the density of the liver veins compared to the density in the vena cava. The LSVAR and LSVR were compared between patients with and without significantly elevated liver stiffness (based on a cutoff value of 3.5 kPa) using the Mann–Whitney U test and ROC curve analysis.

Results
The LSVR and LSVAR allowed significant differentiation between patients with (n = 19) and without (n = 122) significantly elevated liver stiffness (p < 0.001). However, the LSVAR showed a higher area under the curve (AUC = 0.96) than the LSVR (AUC = 0.74). The optimal cutoff value was 0.34 for the LSVR, which detected clinically increased liver stiffness with a sensitivity of 53% and a specificity of 88%. With a cutoff value of 0.67 for the LSVAR, the sensitivity increased to 95% while maintaining a specificity of 89%.

Conclusion
The LSVAR improves the detection of significant liver fibrosis on portal venous CT scans compared to the LSVR.

Published: November 2020

Abstract
Purpose
Nail technicians (NTs) are exposed to a low-level mixture of volatile organic solvents (VOCs), yet the health hazards related to such exposure are unknown. This study thus aimed to compare the blood plasma levels of selected biomarkers related to liver status and lipid profile among occupationally exposed NTs and unexposed controls. Associations between out-of-normal-range levels of such biomarkers and occupational exposure to VOCs mixture have also been investigated.

Methods
The study enrolled 145 female NTs and 152 unexposed controls. Biochemical analyses were performed using spectrophotometric assays and obtained data were analyzed using general linear model and Poisson regression modelling adjusted to multiple confounders.

Results
Compared to controls, NTs presented significantly increased plasma activities of ALT (2.04 ± 0.63 ln-U/l vs. 1.25 ± 0.71 ln-U/l; p < 0.0001) and AST (2.73 ± 0.25 ln-U/l vs. 2.08 ± 0.95 ln-U/l; p < 0.0001), and significantly increased plasma levels of TG (4.38 ± 0.53 ln-mg/dl vs. 4.21 ± 0.42 ln-mg/dl; p < 0.05) and TC/HDL ratio (1.18 ± 0.36 vs. 1.02 ± 0.27; p < 0.0005). Plasma levels of HDL were significantly lower among NTs (4.02 ± 0.29 ln-mg/dl vs. 4.21 ± 0.26 ln-mg/dl; p < 0.0001). Moreover, NTs were found to present significantly increased risk of occurrence of clinically relevant plasma HDL levels below 3.91 ln-mg/dl (i.e., 50 mg/dl; RR = 1.58, 95% CI 1.07–2.32, p < 0.05), as well as increased risk of clinically relevant TC/HDL ratio above the normal range limit of 3.5 (RR = 1.68, 95% CI 1.19–2.35, p < 0.005), as compared to unexposed controls.

Conclusion
Nail technicians are subject to adverse changes in selected plasma biomarkers related to liver functions, some of which may be of clinical relevance.
