Resistivity of REBCO tapes in overcritical current regime: impact on superconducting fault current limiter modeling
Authors: Riva N , Sirois F , Lacroix C , de Sousa W T B , Dutoit B , Grilli F 
Published: July 2020

Abstract
A detailed knowledge of the resistivity of high-temperature superconductors in the overcritical current regime is important to achieve reliable numerical simulations of applications such as superconducting fault current limiters. We have previously shown that the combination of fast pulsed current measurements and finite element analysis allows accounting for heating effects occurring during the current pulses. We demonstrated that it is possible to retrieve the correct current and temperature dependence of the resistivity data points of the superconductor material. In this contribution, we apply this method to characterize the resistivity vs. current and temperature of commercial REBCO tapes in the overcritical current regime, between 77 and 90 K and in self-field conditions. The self-consistency of the overcritical resistivity model

is verified by comparing DC fault measurements with the results of numerical simulations using this model as input. We then analyze by numerical simulation to what extent using the

Abstract
Hardware removal after complete fracture healing is a laborious and traumatic procedure that bears the risks of refracture, infection, and soft tissue damage. Absorbable materials for fracture fixation have the advantage of eliminating the need for removal; however, they may stimulate a considerable inflammatory response. For that reason, we compared in a prospective randomized experimental animal model study the incidence of foreign-body reactions between Inion OTPSTM absorbable plate implants, consisting of carbon trimethylene, L-polylactic acid, and D, L-polylactic acid, and conventional titanium plates. Seventy rabbits were equally divided into two groups. Titanium (Group A) or absorbable (Group B) plates and screws were implanted in the femoral shaft of the rabbits. Wound reaction and laboratory tests including white blood cell count (WBC), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) values were measured and compared at different time points. Radiographs and histological analysis of tissue samples from all animals were also used to identify potential foreign-body reactions. WBC showed normal values in both groups. In Group A, ESR levels were higher at all time points but CRP values were normalized at 3 weeks postoperatively. In Group B, ESR and CRP levels reached a peak at 3 weeks and were above normal values throughout the whole experiment (p < 0.001). Radiologic examination revealed periosteal thickening and surrounding sclerosis in 23 out of 35 animals of Group B (66%). All Group A animals had normal radiographic findings. Histopathology showed a typical non-specific foreign-body reaction in all animals in Group B (100%) but none in Group A. However, only four of them (11.8%) developed non-infected wound complications and showed significantly elevated CRP and ESR values (p = 0.054). Although Inion OTPSTM Biodegradable Plating System stimulates a foreign-body reaction, only a small but not negligible percentage of almost 12% may lead to wound problems. However, this difference compared to titanium plates was of borderline not statistically significant. Future studies should focus on the development of absorbable implants with improved biocompatibility aiming to further decrease the potential of foreign-body reaction and eliminate the need for additional reoperative procedures.
NASA’s carbon monitoring system (CMS) and arctic-boreal vulnerability experiment (ABoVE) social network and community of practice
Authors: Brown Molly E , Cooper Matthew W , Griffith Peter C 
Published: July 2020

Abstract
The NASA Carbon Monitoring System (CMS) and Arctic-Boreal Vulnerability Experiment (ABoVE) have been planned and funded by the NASA Earth Science Division. Both programs have a focus on engaging stakeholders and developing science useful for decision making. The resulting programs have funded significant scientific output and advancements in understanding how satellite remote sensing observations can be used to not just study how the Earth is changing, but also create data products that are of high utility to stakeholders and decisions makers. In this paper we focus on documenting thematic diversity of research themes and methods used, and how the CMS and ABoVE themes are related. We do this through developing a Correlated Topic Model on the 521 papers produced by the two programs and plotting the results in a network diagram. Through analysis of the themes in these papers, we document the relationships between researchers and institutions participating in CMS and ABoVE programs and the benefits from sustained engagement with stakeholders due to recurring funding. We note an absence of policy engagement in the papers and conclude that funded researchers need to be more ambitious and explicit in drawing the connection between their research and carbon policy implications in order to meet the stated goals of the CMS and ABoVE programs.

Published: July 2020

Abstract
Drop-on-demand (DoD) inkjet printing has been explored for a range of applications, including those to selectively deposit cellular material, due to the high accuracy and scalability of such systems when compared with alternative bioprinting techniques. Despite this, there remain considerable limitations when handling cell suspensions due to the agglomeration and sedimentation of cells during printing, leading to a deterioration in jetting performance. The objective of this work was to design and assess the effectiveness of a custom agitation system to maintain cellular dispersion within the ink reservoir during printing. The cell printing performance of an inkjet printer was assessed with and without the use of a custom agitation system, with biological characterisation performed to characterise the impact of the agitator on cellular viability and function. Cell printing performance was retained over a 2 h printing period when incorporating an agitated reservoir, with a gradual reduction in performance observed under a non-agitated configuration. Cell assays indicated that the agitation process did not significantly affect the viability, metabolic activity or morphology of the mesenchymal stromal cell (MSC) or chondrocyte cell types. This study therefore provides a new methodology to increase process reliability within DoD printing platforms when jetting cellularised material.
Thioflavin T as a noncovalent reporter for a label-free, non-enzymatic, catalytic DNA amplifier

Published: July 2020

Abstract
DNA-DNA reactions can be monitored with a label-free fluorogenic reaction. Guanosine-rich, single-stranded DNA oligonucleotides bind to thioflavin-T (ThT) and enhance the fluorescence of the dye. We discovered a novel DNA sequence that produces fluorescence upon binding to ThT. We denote this oligonucleotide ThTSignal. We use ThTSignal as a label-free reporter for the activity of several designed DNA-DNA reactions (DNA circuits). The DNA circuits conditionally produce the ThTSignal oligonucleotide by association or by liberating the ThTSignal oligonucleotide from double-stranded DNA. This strategy offers label-free, cost-effective, fluorogenic detection of the molecular beacon reaction, split reporter reaction, one-step strand displacement reaction, and the entropy-driven amplifier reaction (a catalytic DNA circuit).

Abstract
In recent experiments, a significant band gap widening was observed when Sb was substituted for Bi in the double-perovskite Ba2PrBiO6. In this work, we study a series of double-perovskites, Ba2BiIIIBiVO6, Ba2PrBiO6, and Ba2PrSbO6 using the first-principles density functional theory with the Heyd-Scuseria-Ernzerhof hybrid functional to investigate the substitution effect on the structural and electronic properties. We find that the two topmost valence bands are disappeared on the substitution of PrIII for BiIII, and the two bottommost conduction bands are disappeared on the substitution of SbV for BiV, causing the significant band gap widening. Further, our calculation suggests that the Ba2PrPrBiO6 is a possible candidate as a source of the PrIV signal observed in the experiment. We find that the B-site disordering atomic configuration, Ba2
B″V
B′IIIO6, are restored to those of the original structures. On the other hand, our results also suggest the importance of the partial B-site disorder to explain the experimentally observed band gaps.
Study on the hygrothermal aging behavior and diffusion mechanism of Ti/CF/PMR polyimide composite laminates

Published: July 2020

Abstract
A series of hygrothermal aging experiments were performed on Ti/CF/PMR polyimide (TCPP) composite laminates in this work in order to verify the moisture diffusion characteristics and diffusion mechanism of the laminate. The specimens were subjected to various hygrothermal aging parameters, specifically 70 °C/95RH%, 85 °C/75RH%, 85 °C/85RH% and 90 °C/95RH%. The results illustrate that the temperature affected the diffusion rate of water molecules in the composite laminates, and the relative humidity determined the saturated moisture absorption rate. For the orthogonally laminated TCPP composite laminates, two equations have been obtained to predict the saturated moisture absorption and diffusion rate of water molecules of the prepreg layer. Additionally, the moisture absorption as a function of time has been expressed for the prepreg layer.

Cell degradation quantification—a performance metric-based approach
Authors: Zhang Yulun , Wang Qiang , Liaw Boryann , Nagpure Shrikant C , Dufek Eric J , Dickerson Charles C 
Published: July 2020

Abstract
A safe and reliable battery operation needs effective diagnostic tools. A quantitative failure analysis (FA) to enable cell qualification and quantify its effectiveness for reliable and safe operation of rechargeable Li batteries (RLB) is shown here. The method can identify and quantify potential failure based on the state of charge (SOC) under any operating conditions. A precise and accurate electrochemical analytic diagnosis (eCAD) of 14 rechargeable Li || NMC-622 cells of the same build are used as an example. The FA by eCAD can quantitatively decipher good, bad and ugly cells in cycle aging. The cell qualification is based on thermodynamic SOC, not experimental conditions. The method provides a quantitative failure mode and effect analysis to reveal diverse ‘dead Li’ formation that affects the reversibility of the Li anode and charge retention in the cell. This cell qualification method highlights the potential to improve cell quality for safe operation, with strong implications for early fault detection, FA, risk mitigation, state estimation and life prediction for reliable and safe RLB operations.

Abstract
Interface structures in complex oxides remain an active area of condensed matter physics research, largely enabled by recent advances in scanning transmission electron microscopy (STEM). Yet the nature of the STEM contrast in which the structure is projected along the given direction precludes separation of possible structural models. Here, we utilize deep convolutional neural networks (DCNN) trained on simulated 4D STEM datasets to predict structural descriptors of interfaces. We focus on the widely studied interface between LaAlO3 and SrTiO3, using dynamical diffraction theory and leveraging high performance computing to simulate thousands of possible 4D STEM datasets to train the DCNN to learn properties of the underlying structures on which the simulations are based. We test the DCNN on simulated data and show that it is possible (with >95% accuracy) to identify a physically rough from a chemically diffuse interface and create a DCNN regression model to predict step positions. We quantify the applicability of the model to different thicknesses and the transferability of the approach. The method shown here is general and can be applied for any inverse imaging problem where forward models are present.
The Loss of Sociality Is Accompanied by Reduced Neural Investment in Mushroom Body Volume in the Sweat Bee Augochlora Pura (Hymenoptera: Halictidae)
Authors: Pahlke Sarah , Seid Marc A , Jaumann Sarah , Smith Adam 
Published: July 2020

Abstract
Social behavior has been predicted to select for increased neural investment (the social brain hypothesis) and also to select for decreased neural investment (the distributed cognition hypothesis). Here, we use two related bees, the social Augochlorella aurata (Smith) (Hymenoptera: Halictidae) and the related Augochlora pura (Say), which has lost social behavior, to test the contrasting predictions of these two hypotheses in these taxa. We measured the volumes of the mushroom body (MB) calyces, a brain area shown to be important for cognition in previous studies, as well as the optic lobes and antennal lobes. We compared females at the nest foundress stage when both species are solitary so that brain development would not be influenced by social interactions. We show that the loss of sociality was accompanied by a loss in relative neural investment in the MB calyces. This is consistent with the predictions of the social brain hypothesis. Ovary size did not correlate with MB calyx volume. This is the first study to demonstrate changes in mosaic brain evolution in response to the loss of sociality.
Practical considerations in prevention and treatment of venous thromboembolism in hospitalized patients with COVID-19
Authors: Smith Kelly , Krajewski Kristin C , Krajewski Michael P 
Published: July 2020

Abstract

Purpose
There are increasing reports in the literature of high rates of coagulopathy and venous thromboembolism (VTE) among hospitalized patients with coronavirus disease 2019 (COVID-19). Understanding of these abnormalities is continually evolving, but these conditions may pose a risk to patients with COVID-19 beyond the risk typically seen in critically ill patients.

Summary
There are currently no widely accepted evidence-based guidelines regarding specifics related to treatment and prevention of COVID-19–related coagulopathies. Areas of management requiring clinical equipoise include agent selection and dosing, continuation vs interruption of home oral anticoagulant therapy during hospital admission, and postdischarge VTE prophylaxis. Clinicians may wish to consider use of a stratified, 3-tiered approach of low-intensity anticoagulation, intermediate-intensity anticoagulation, and therapeutic-dose anticoagulation. Patients can be categorized by tier depending on their risk factors for VTE, acuity of illness, and laboratory values such as D-dimer level.

Conclusion
Practical guidance on anticoagulation considerations and dosing suggestions are provided to assist clinicians faced with challenging anticoagulation-related situations in caring for hospitalized patients with COVID-19 until formal evidence-based guidelines become available.
Combined Effects of Physical Behavior Compositions and Psychosocial Resources on Perceived Exertion Among Eldercare Workers

Published: July 2020

AbstractObjectivesHigh perceived physical exertion is common in eldercare workers and a strong predictor for impaired health. However, little is known on how physical behaviors at work associate with physical exertion in this group. The aim of this study was to determine the extent to which the composition of physical behaviors at work is associated with perceived physical exertion in nursing home eldercare workers, and the extent to which these associations are modified by psychosocial resources.MethodsOur population consisted of 399 female eldercare workers from 126 wards in 20 different nursing homes. We evaluated time spent in physical behaviors at work [sitting, standing still, light activities (LAs), and moderate to vigorous activities (MVAs)] using triaxial accelerometers worn, on average, for three working days. We accounted for inherent codependency between the behaviors using compositional data analysis. We used multilevel linear mixed regression models to determine associations between the behaviors and perceived exertion, measured on a numeric rating scale (0–10), and included interactions between each behavior and psychosocial resources (influence at work, social support, and quality of leadership) to determine a possible moderating effect of resources. Regression results were illustrated using isotemporal substitution.ResultsSitting was negatively (β: −0.64; P &lt; 0.01) while MVA was positively (β: 0.95; P = 0.02) associated with perceived exertion. According to isotemporal substitution, replacing 30 min of MVA by sitting would, for an average worker, be associated with a decrease in physical exertion by −0.14 on the 0–10 scale. Job resources marginally moderated the association between LA and exertion. Thus, among workers with low influence and low social support, we found a positive association between LA and exertion, while that was not found for workers with medium or high influence and support (interactions for influence and support: P = 0.08 and P = 0.10).ConclusionsOur findings suggest that reallocating time from MVA to sitting can mitigate perceived physical exertion in eldercare workers. More time in LA increased physical exertion only for workers with low psychosocial resources, supporting a positive effect of a better psychosocial work environment in elderly care.

Authors: Bertossi Dario , Malchiodi Luciano , Albanese Massimo , Nocini Riccardo , Nocini Pierfrancesco 
Published: July 2020

Abstract

Background
Nonsurgical aesthetic treatment of the nose is becoming increasingly popular. VYC-25L is a novel hyaluronic acid product with the high G’ and cohesivity required of a nasal filler.

Objectives
The authors sought to assess the safety and efficacy of VYC-25L for treatment of the nose utilizing a previously published, grid-based protocol.

Methods
This was a retrospective, single-center analysis of data from adult patients undergoing treatment of the nose with VYC-25L between February and April 2019 utilizing the grid system as the reference for injection quantity and sequencing. Specific procedures included correction of inadequate projection, deep glabella treatment, correction of a nasal hump, and adjustment of the nasolabial angle and columella. Patients were followed-up for 6 to 9 months.

Results
A total of 61 patients were included in the analysis (mean age, 32 ± 3 years; n = 45 females [74%]). At 2 weeks posttreatment, a high degree of defect correction was confirmed based on independent evaluation, with all patients scoring 9 or 10 on a 10-point visual analog scale. Fifty-nine of 61 patients (97%) self-assessed the degree of correction as “adequate.” Results were stable at 3- and 6-month follow-up visits. Complications recorded were bruising (n = 15, 25%), asymmetry (n = 2, 3%), and hematoma (n = 1, 2%). All resolved rapidly. There were no cases of infection, bumps, or skin necrosis.

Conclusions
VYC-25L is safe and efficacious for treatment of the nose, with high levels of patient satisfaction. It has potential to be a valuable tool in nonsurgical rhinoplasty.

Squamous Cell Carcinoma as a Result of Likely Industrial Grade Ruptured Poly Implant Prosthèse Silicone Buttock Implants
Authors: Camacho Juan P , Obaíd Miguel , Bustos Camilo , Calderón Wilfredo , Lombardi Juan J , Subiabre Rodrigo , Guler Kenneth , Correa Francisca 
Published: July 2020

Abstract

The Poly Implant Prosthèse (PIP) implants were withdrawn from the market in 2010 due to the use of a nonmedical grade silicone filler. In 2012, the French medical authorities and the International Confederation of Societies of Plastic, Reconstructive and Aesthetic Surgery recommended the extraction of PIP implants. However, during the duration of this scandal, each country in the world did not agree with a uniform procedure, and this rule was not implemented in its entirety. Although laboratory test results on PIP implants were negative for cytotoxicity and genotoxicity, there are many reports in the literature of several complications associated with PIP implants, including high rupture rates and the fact that they are 3 to 5 times more likely to produce local tissue reactions. On the other hand, the development of more strange and worse prognosis complications, such as the development of squamous carcinoma associated with the use of silicone implants (not necessarily related to PIP implants), is less known. To date, only 6 cases have been reported, and all are related to breast augmentation. The authors made the first report of primary gluteal squamous cell cancer related to rupture and delayed removal of PIP silicone buttock implants.
