Synchrotron X-ray Study on Plaston in Metals
Authors: Adachi Hiroki 
Published: January 2022

AbstractGrain refinement is one of the methods applied to strengthen metallic materials, and various peculiar mechanical properties have been reported to be expressed when the grain size is reduced to less than submicron dimensions. This is considered to be due to a change in the behavior of dislocations that are associated with plastic deformation. In situ synchrotron radiation measurements of microstructural changes during deformation in face-centered cubic (fcc) metals with grain sizes of 20 μm to 5 nm were performed to systematically investigate the effects of grain size on dislocation behavior during plastic deformation. In pure aluminum with grain sizes of 20 to 3 μm, the dislocation density during plastic deformation was approximately 1014 m−2, regardless of the grain size. However, when the grain size was less than 3 μm, the dislocation density increased monotonically in proportion to the grain size to the power of -1. Furthermore, in a nickel alloy with a grain size of less than 10 nm, this relationship was no longer satisfied, and the results suggested that deformation progresses due to partial dislocations. In materials with a grain size of less than 1 μm, the dislocation density after unloading became much smaller than that during loading.
Calculated versus measured iron losses and instantaneous magnetization power functions of electrical steel
Authors: Pfützner Helmut , Shilyashki Georgi , Huber Emanuel 
Published: January 2022

AbstractMagnetic energy loss P of soft magnetic laminations like SiFe sheets tends to be expressed through an integral over the power product H · dB/dt. Already in earlier papers, we stressed that distinctions are needed for the quantities H and B. However, they are not considered in practically consistent ways, in the so far literature. Here, we discuss these distinctions in closer ways, comparing loss determination by calculation and measurement, respectively. A physically consistent procedure is described for the determination of loss and magnetization power functions through measurement of bi-located quantities HS and BC (S surface, C cross section). On the other hand, it is concluded that corresponding quantitative calculations—based on co-located quantities H and B—are impeded by the high amount of technological parameters of modern steel products. For example, they result from chemical additions, and—in particular—also from specific technologies of rolling, annealing, coating or scribing.

Published: January 2022

ZusammenfassungBei Vorliegen einer symptomatischen epiretinalen Gliose wird im klinischen Alltag in der Regel eine Pars-plana-Vitrektomie mit Membranpeeling zur Entfernung der Membran indiziert. Nach gängiger klinischer Erfahrung existiert nahezu keine selbstständige Regression einer solchen epiretinalen Membran und somit einer alleinigen Abheilung der Pathologie. Beschrieben wird daher der ungewöhnliche Fall einer beidseitigen selbstständigen Regression einer idiopathischen epiretinalen Gliose mit Makulaschichtforamen bei einem 73-jährigen Patienten. Überlegungen zum möglichen Mechanismus werden auf Basis der vorhandenen Literatur vorgestellt. Diese beinhalten die Trennung entzündlicher vs. nichtentzündlicher Membranen, mögliche Separation einzelner Schichten in Abhängigkeit vom Status der hinteren Glaskörpergrenzmembran, aber auch das mögliche Wirken proteolytischer Systeme im Bereich des hinteren Glaskörpers. Es stellt sich schließlich die Frage, ob Patienten vor möglicher Operation über diesen Umstand mit aufgeklärt werden müssen.
Rapid estimation of viral emission source location via genetic algorithm
Authors: Clemon L. M. 
Published: January 2022

AbstractIndoor spread of infectious diseases is well-studied as a common transmission route. For highly infectious diseases, like Sars-CoV-2, considering poorly or semi ventilated areas outdoors is increasingly important. This is important in communities with high proportions of infected people, highly infectious variants, or where spread is difficult to manage. This work develops a simulation framework based on probabilistic distributions of viral particles, decay, and infection. The methodology reduces the computational cost of generating rapid estimations of a wide variety of scenarios compared to other simulation methods with high computational cost and more fidelity. Outdoor predictions are provided in example applications for a gathering of five people with oscillating wind and a public speaking event. The results indicate that infection is sensitive to population density and outdoor transmission is plausible and likely locations of a virtual super-spreader are identified. Outdoor gatherings should consider precautions to reduce infection spread.

Published: January 2022

AbstractThe repellency and toxicity of a CO2-derived cedarwood oil (CWO) was evaluated against actively questing unfed nymphs of four species of hard ticks: Amblyomma americanum (L.), Dermacentor variabilis (Say), Ixodes scapularis Say, and Rhipicephalus sanguineus (Latreille). Using a vertical climb bioassay for repellency, nymphs of these species avoided a CWO-treated filter paper in proportional responses to treatment concentrations. At 60 min of exposure, I. scapularis nymphs were most sensitive with 50% repellency concentration (RC50) of 19.8 µg cm−2, compared with RC50 of 30.8, 83.8 and 89.6 µg cm−2 for R. sanguineus, D. variabilis and A. americanum, respectively. Bioassays determined the lethal concentration for 50% (LC50) and 90% (LC90) mortality of nymphs exposed to CWO in treated vials after 24- and 48-h exposure. After 24 h exposure, the LC50 values were 1.25, 3.45 and 1.42 µg cm−2 and LC90 values were 2.39, 7.59 and 4.14 µg cm−2 for D. variabilis, I. scapularis and R. sanguineus, respectively, but had minimal effect on A. americanum. After 48 h exposure, the LC50 values were 4.14, 0.78, 0.79 and 0.52 µg cm−2, and LC90 values were 8.06, 1.48, 1.54 and 1.22 µg cm−2 for A. americanum, D. variabilis, I. scapularis and R. sanguineus, respectively. The repellency of CWO on tick species decreased with time. The repellency and toxicity bioassays demonstrated concentration-dependent responses of tick nymphs to the oil, indicating the potential of the CO2-derived cedarwood oil be developed as an eco-friendly repellent and/or acaricide.

Published: January 2022

AbstractIn this paper, we discuss previous research in automatic prediction of court decisions. We define the difference between outcome identification, outcome-based judgement categorisation and outcome forecasting, and review how various studies fall into these categories. We discuss how important it is to understand the legal data that one works with in order to determine which task can be performed. Finally, we reflect on the needs of the legal discipline regarding the analysis of court judgements.

AbstractWe project climate change induced changes in fluvial flood risks for six global warming levels between 1.5 and 4 °C by 2100, focusing on the major river basins of six countries. Daily time series of precipitation, temperature and monthly potential evapotranspiration were generated by combining monthly observations, daily reanalysis data and projected changes in the five CMIP5 GCMs also selected in the ISI-MIP fast track project. These series were then used to drive the HBV hydrological model and the CaMa-Flood hydrodynamic model to simulate river discharge and flood inundation. Our results indicate that return periods of 1 in 100-year floods in the late twentieth century (Q100-20C) are likely to decrease with warming. At 1.5 °C warming, 47%, 66%, 27%, 65%, 62% and 92% of the major basin areas in Brazil, China, Egypt, Ethiopia, Ghana and India respectively experience a decrease in the return period of Q100-20C, increasing to 54%, 81%, 28%, 82%, 86% and 96% with 4 °C warming. The decrease in return periods leads to increased number of people exposed to flood risks, particularly with 4 °C warming, where exposure in the major river basin areas in the six countries increases significantly, ranging from a doubling (China) to more than 50-fold (Egypt). Limiting warming to 1.5 °C would avoid much of these increased risks, resulting in increases ranging from 12 to 1266% for the 6 countries.

AbstractThis paper explores the subjective experiences of mental health practitioners, people with psychosis and carers, on social isolation and community integration of people with psychosis. Focus groups and one-to-one interviews with 80 adult participants across three sites in the UK were conducted. Audio recordings were transcribed and analysed using thematic analysis. Participants commented on various aspects that may cause social isolation or enable community integration, including institutional factors (lack of resources, hospitalisation impact), illness symptoms (e.g., paranoia; over-pathologising vs individual choice), stigma (particularly the psychosis label), and the importance of communities that foster agency and embrace change. Hospitalisation maybe be a cause for isolation and psychiatric wards should consider allowing for socialisation as a therapeutic tool. Initiatives should consider the social fabric of our communities, socioeconomic inequalities and stigmatisation. Building communities that are accepting, kind and flexible can create opportunities that could lead to independence from mental health services.
Parent–Child Interaction Therapy for Children with Disruptive Behaviors and Autism: A Randomized Clinical Trial

Published: January 2022

AbstractA relatively large number of children with autism spectrum disorder (ASD) exhibit disruptive behavioral problems. While accumulating data have shown behavioral parent training programs to be efficacious in reducing disruptive behaviors for this population, there is a dearth of literature examining the impact of such programs across the range of ASD severity. To evaluate the effectiveness of Parent–Child Interaction Therapy (PCIT), an evidence-based treatment for children with problem behaviors and their families, in reducing disruptive behaviors among children (4–10 years) with ASD (without intellectual disabilities). Fifty-five children (85.5% male, 7.15 years;SD1.72) were enrolled from pediatric offices and educational settings into a randomized clinical trial (PCIT:N = 30; Control:N = 25). PCIT families demonstrated a significant reduction in child disruptive behaviors, increase in positive parent–child communication, improvement in child compliance, and reduction in parental stress compared to the control group. Exploratory analyses revealed no differential treatment response based on ASD severity, receptive language, and age. Results are promising for the use of PCIT with children demonstrating disruptive behaviors across the autism spectrum.

AbstractDuctal carcinoma in situ (DCIS) of the breast is able to induce stromal changes, which likely reflect the crosstalk between DCIS and its microenvironment. These changes harbor prognostic information, although the interobserver variability of scoring stromal changes is moderate. A more robust evaluation of the DCIS-associated stroma is therefore needed. The aim of this study was to characterize P4HA2 expression, which is involved in collagen biosynthesis, in DCIS and to assess whether P4HA2 expression enables a more robust evaluation of the DCIS-associated stroma compared to histomorphology. This study included 410 patients with DCIS. Stromal changes were scored on hematoxylin/eosin-stained whole slides. P4HA2 expression in DCIS-associated stroma was assessed by whole slide immunohistochemistry. One hundred DCIS lesions were evaluated by seven pathologists to study the interobserver variability in the assessment of stromal changes and stromal P4HA2 expression. High P4HA2 expression in stromal fibroblasts was present in 14.1% of the patients. High P4HA2 expression was associated with the presence of periductal stromal changes (P = 0.004). The interobserver variability was similar for the assessment of stromal changes and the percentage of P4HA2-positive fibroblasts. Although we demonstrated a significant association between high P4HA2 expression in fibroblasts and the morphological presence of stromal changes, it seems unlikely that P4HA2 expression can be used as an alternative for the histopathological evaluation of the DCIS-associated stroma.
Randomness in Compressible Fluid Flows Past an Obstacle
Authors: Feireisl Eduard , Hofmanová Martina 
Published: January 2022

AbstractWe consider a statistical limit of solutions to the compressible Navier–Stokes system in the high Reynolds number regime in a domain exterior to a rigid body. We investigate to what extent this highly turbulent regime can be modeled by an external stochastic perturbation, as suggested in the related physics literature. To this end, we interpret the statistical limit as a stochastic process on the associated trajectory space. We suppose that the limit process is statistically equivalent to a solution of the stochastic compressible Euler system. Then, necessarily, the stochastic forcing is not active—the limit is a statistical solution of the deterministic Euler system; the solutions S-converge to the limit; if, in addition, the expected value of the limit process solves the Euler system, then the limit is deterministic and the convergence is strong in the $$L^p$$

Influence of a ward-based pharmacist on the medication quality of geriatric inpatients: a before–after study
Authors: Kiesel Esther Katharina , Drey Michael , Pudritz Yvonne Marina 
Published: January 2022

AbstractBackground Despite several international studies demonstrating that ward-based pharmacists improve medication quality, ward pharmacists are not generally established in German hospitals. Aim We assessed the effect of a ward-based clinical pharmacist on the medication quality of geriatric inpatients in a German university hospital. Method The before-after study with a historic control group was conducted on the geriatric ward. During the control phase, patients received standard care without the involvement of a pharmacist. The intervention consisted of a clinical pharmacist providing pharmaceutical care from admission to discharge. Medication quality was measured on admission and discharge using the Medication Appropriateness Index (MAI). A linear regression analysis was conducted to calculate the influence of the intervention on the MAI. Results Patients in the intervention group (n = 152, mean 83 years) were older and took more drugs at admission compared to the control group (n = 159, 81 years). For both groups, the MAI per patient improved significantly from admission to discharge. Although the intervention did not influence the summated MAI score per patient, the intervention significantly reduced the MAI criteria Dosage (p = 0.006), Correct Directions (p = 0.016) and Practical Directions (p = 0.004) as well as the proportion of overall inappropriate MAI ratings (at least 1 of 9 criteria inappropriate) (p = 0.015). Conclusion Although medication quality was already high in the control group, a ward-based clinical pharmacist could contribute meaningfully to the medication quality on an acute geriatric ward.

ambiguity in the orientation of the transverse component. The successful launch and operation of Solar Orbiter have made the removal of the 180∘ ambiguity possible using solely observations obtained from two different vantage points. While the exploitation of such a possibility is straightforward in principle, it is less so in practice, and it is therefore important to assess the accuracy and limitations as a function of both the spacecrafts’ orbits and measurement principles. In this work, we present a stereoscopic disambiguation method (SDM) and discuss thorough testing of its accuracy in applications to modeled active regions and quiet-Sun observations. In the first series of tests, we employ magnetograms extracted from three different numerical simulations as test fields and model observations of the magnetograms from different angles and distances. In these more idealized tests, SDM is proven to reach a 100% disambiguation accuracy when applied to moderately-to-well resolved fields. In such favorable conditions, the accuracy is almost independent of the relative position of the spacecraft with the obvious exceptions of configurations where the spacecraft are within a few degrees of co-alignment or quadrature. Even in the case of disambiguation of quiet-Sun magnetograms with significant under-resolved spatial scales, SDM provides an accuracy between 82% and 98%, depending on the field strength. The accuracy of SDM is found to be mostly sensitive to the variable spatial resolution of Solar Orbiter in its highly elliptic orbit, as well as to the intrinsic spatial scale of the observed field. Additionally, we provide an example of the expected accuracy as a function of time that can be used to optimally place remote-sensing observing windows during Solar Orbiter observation planning. Finally, as a more realistic test, we consider magnetograms that are obtained using a radiative-transfer inversion code and the SO/PHI Software siMulator (SOPHISM) applied to a 3D-simulation of a pore, and we present a preliminary discussion of the effect of the viewing angle on the observed field. In this more realistic test of the application of SDM, the method is able to successfully remove the ambiguity in strong-field areas.
Review of cooling techniques used to enhance the efficiency of photovoltaic power systems

Published: January 2022

AbstractPhotovoltaic (PV) panels are one of the most important solar energy sources used to convert the sun’s radiation falling on them into electrical power directly. Many factors affect the functioning of photovoltaic panels, including external factors and internal factors. External factors such as wind speed, incident radiation rate, ambient temperature, and dust accumulation on the PV cannot be controlled. The internal factors can be controlled, such as PV surface temperature. Some of the radiation falling on the surface of the PV cell turns into electricity, while the remainder of incident radiation is absorbed inside the PV cell. This, in turn, elevates its surface temperature. Undesirably, the higher panel temperature, the lower conversion performance, and lesser reliability over the long term occur. Hence, many cooling systems have been designed and investigated, aiming to effectively avoid the excessive temperature rise and enhance their efficiency. Many cooling methods are used to cool solar cells, such as passive cooling, active cooling, cooling with phase change materials (PCMs), and cooling with PCM with other additives such as nanoparticles or porous metal. In this work, the common methods utilized for cooling PV panels are reviewed and analyzed, focusing on the last methods, and summarizing all the researches that dealt with cooling PV solar cells with PCM and porous structures.

Abstract
Background
Portal vein thrombosis (PVT) and venous thromboembolism (VTE) are fearsome complications of liver cirrhosis.

Objectives
To assess the prevalence and the main risk factors for venous thrombotic complications in hospitalized cirrhotic patients.

Patients/methods
We retrospectively reviewed electronic administrative discharge data of 19461 cirrhotic patients hospitalized over a 35-year period; univariate and multivariate logistic regression was used to asses risk factors for PVT or VTE and their impact on hospital stay and mortality.

Results
382 out of 7445 patients (5.1%) were diagnosed with PVT and 95 (1.3%) with VTE. Liver cirrhosis complications were observed in 45% of patients. Hepatic encephalopathy (HE) (OR 13.88 [10.76–17.98] p < 0.0001), endoscopic signs of portal hypertension (OR 1.33 [1.02–1.75] p = 0.02), hepatocellular carcinoma (HCC) (OR 4.59 [3.6–5.84] p < 0.0001), diabetes (OR 1.68 [1.27–2.22] p = 0.0001), abdominal surgery/invasive procedures (OR 2.03 [1.56–2.64] p < 0.0001) emerged as independent predictors of PVT. Higher risk of VTE was observed in patients with HE (OR 3.21 [1.78–5.79] p < 0.0001), HCC (OR 1.98 [1.23–3.19] p = 0.002) or other tumors (OR 2.48 [1.42–4.32] p = 0.001), acute illnesses (infections OR 3.01 [1.84–5.05] p = 0.0001; cardiac/respiratory insufficiency OR 2.4 [1.27–4.53] p = 0.003; acute myocardial infarction/stroke OR 7.86 [1.76–35.12] p = 0.003). VTE was the only independent predictor of in-hospital mortality (OR 4.45 [1.05–18.81] p = 0.042).

Conclusions
Liver disease complications related to portal hypertension, HCC or other tumors, diabetes, acute illnesses (i.e. infections, cardiac/pulmonary insufficiency, acute myocardial infarction/stroke) and abdominal interventions are associated with increased risk of PVT or VTE in hospitalized cirrhotic patients, and should be considered to define personalized preemptive approaches.
