Wireless communication and wireless power transfer system for implantable medical device
Authors: Zhang Zhang , Chen Chao , Fei Tairan , Xiao Hao , Xie Guangjun , Cheng Xin 
Published: September 2020

Abstract
Traditional magnetically coupled resonant wireless power transfer technology uses fixed distances between coils for research, to prevent fluctuations in the receiving voltage, and lead to reduce transmission efficiency. This paper proposes a closed-loop control wireless communication wireless power transfer system with a wearable four-coil structure to stabilize the receiving voltage fluctuation caused by changes in the displacement between the coils. Test results show that the system can provide stable receiving voltage, no matter how the distance between the transmitting coil and the receiving coil is changed. When the transmission distance is 20 mm, the power transfer efficiency of the system can reach 18.5% under the open-loop state, and the stimulus parameters such as the stimulation period and pulse width can be adjusted in real time through the personal computer terminal.
Seasonal impact-based mapping of compound hazards
Authors: Hillier J K , Dixon R S 
Published: September 2020

Abstract
Impact-based, seasonal mapping of compound hazards is proposed. It is pragmatic, identifies phenomena to drive the research agenda, produces outputs relevant to stakeholders, and could be applied to many hazards globally. Illustratively, flooding and wind damage can co-occur, worsening their joint impact, yet where wet and windy seasons combine has not yet been systematically mapped. Here, seasonal impact-based proxies for wintertime flooding and extreme wind are used to map, at 1° × 1° resolution, the association between these hazards across Europe within 600 years as realized in seasonal hindcast data. Paired areas of enhanced-suppressed correlation are identified (Scotland, Norway), and are shown to be created by orographically-enhanced rainfall (or shelter) from prevailing westerly storms. As the hazard metrics used are calibrated to losses, the maps are indicative of the potential for damage.
Impact of ocean model resolution on understanding the delayed warming of the Southern Ocean
Authors: Bilgen Simge I , Kirtman Ben P 
Published: September 2020

Abstract
Currently available historical climate change simulations indicate a relatively delayed Southern Ocean warming, particularly poleward of the Antarctic Circumpolar Current (ACC) compared much of the rest of the globe. However, even this simulated delayed warming is inconsistent with observational estimates which show a cooling trend poleward of the ACC for the period 1979–2014. A fully coupled model run at two resolutions, i.e. ocean eddy parameterized and ocean eddy resolving, driven by historical and fixed CO2 concentration is used to investigate forced trends south of the ACC. We analyze the 1961–2005 Southern Ocean surface and upper ocean temperatures trends simulated by the model and observational estimates to understand the observed trends in the SO. At both resolutions, the models successfully reproduce the observed warming response for the northern flank of the ACC. The eddy resolving simulations, however, are able to reproduce the observed near Antarctic cooling in contrast to the eddy parameterized simulation which shows a warming trend. The cause of this inconsistency between the observations and the ocean eddy parameterized climate models is still a matter of debate, and we show here results that suggest resolved ocean meso-scale processes may be an integral part of capturing the observed trends in the Southern Ocean.

A many-body heat engine at criticality
Authors: Fogarty Thomás , Busch Thomas 
Published: September 2020

Abstract
We show that a quantum Otto cycle in which the medium, an interacting ultracold gas, is driven between a superfluid and an insulating phase can outperform similar single particle cycles. The presence of an energy gap between the two phases can be used to improve performance, while the interplay between lattice forces and the particle distribution can lead to a many-body cooperative effect. Since finite time driving of this cycle can create unwanted non-equilibrium dynamics which can significantly impair the performance of the engine cycle, we also design an approximate shortcut to adiabaticity for the many-body state that can be used to achieve an efficient Otto cycle around a critical point.

Abstract
Wearable electronics, conformable sensors, and soft/micro-robotics require conductive yet stretchable thin films. However, traditional free standing metallic thin films are often brittle, inextensible, and must be processed in strict environments. This limits implementation into soft technologies where high electrical conductivity must be achieved while maintaining high compliance and conformability. Here we show a liquid metal elastomeric thin film (LET) composite with elastomer-like compliance (modulus < 500 kPa) and stretchability (>700%) with metallic conductivity (sheet resistance < 0.1 Ω/□). These 30–70 µm thin films are highly conformable, free standing, and display a unique Janus microstructure, where a fully conductive activated side is accompanied with an opposite insulated face. LETs display exceptional electro-mechanical characteristics, with a highly linear strain-resistance relationship beyond 700% deformation while maintaining a low resistance. We demonstrate the multifunctionality of LETs for soft technologies by leveraging the unique combination of high compliance and electrical conductivity with transfer capabilities for strain sensing on soft materials, as compliant electrodes in a dielectric elastomeric actuator, and as resistive heaters for a liquid crystal elastomer.

Published: September 2020

Abstract

Objectives
We investigate the potential role of BRAF testing in guiding surgical intervention in papillary thyroid carcinoma (PTC).

Methods
Thyroid fine-needle aspiration (FNA) cases with available BRAF result and follow-up thyroidectomy for PTC were included in the study. Cytology and surgical diagnoses were correlated with BRAF status.

Results
There were 151 cases of thyroid FNA specimens with BRAF testing (70 mutant and 81 wild-type BRAF) and histologically confirmed unilateral, unifocal PTCs. There were no differences in age, sex, tumor size, or lymphovascular invasion on thyroidectomy specimens between mutant and wild-type BRAF cases. BRAF mutation was significantly associated with cytology diagnosis (P &lt; .001), PTC subtype (P &lt; .001), extrathyroidal extension (ETE) (P = .006), and higher tumor (T) stage (P = .04). However, an analysis within the histologic subtypes of PTC revealed no significant association between BRAF mutation and ETE or higher T stage. There was also no difference in central (P = .847) or lateral (p = 1) neck lymph node (LN) metastasis.

Conclusions
BRAF mutation identified in thyroid FNA specimens correlates with histologic subtypes but is not an independent factor for predicting PTC biological behavior and should not be used to guide the extent of LN dissection.
Enhancing Punishment or Repairing Harms? Perceptions of Sentencing Hate Crimes Amongst Members of a Commonly Targeted Victim Group
Authors: Walters Mark A , Paterson Jenny L , Brown Rupert 
Published: September 2020

AbstractThis article investigates the attitudes and emotional reactions of LGBT+ people to enhanced sentencing (ES) and restorative justice (RJ) interventions for hate crime. When forced to choose between interventions, our survey (N = 589) found a preference for the use of RJ over ES, which was perceived to be better at reducing reoffending and supporting victims. Nevertheless, the study found greater average levels of support for the use of ES for hate crime, which was predicted by previous experiences of hate crime, perceptions of threat and feelings of anger. An additional experiment (N = 120) revealed RJ, in response to a hate crime, elicited less anger and sadness and higher levels of satisfaction compared with an ES intervention.
Untargeted SPME–GC–MS Characterization of VOCs Released from Spray Paint
Authors: Tiessen Mitchell , Stock Naomi L , Stotesbury Theresa 
Published: September 2020

Abstract
Paints are a common form of physical evidence encountered at crime scenes. This research presents an optimized method for the untargeted analysis of volatile organic compounds (VOCs) in spray paint using solid-phase microextraction–gas chromatography–mass spectrometry (SPME–GC–MS). The presence and persistence of VOCs were monitored in 30 minute intervals, over a 4 hour period, in a triplicate time study. As predicted, spray paint solvents are lost to the environment readily, whereas few VOCs remained present in the headspace in low concentrations beyond 4 hours. The VOCs that were observed to have the highest persistence in the headspace were aromatic compounds and those with longer hydrocarbon chains. We present this study in a forensic science context and suggest that the interpretation of the results may be useful for forensic applications in establishing a time since deposition of a spray-painted surface.
Paediatric Inflammatory Multisystem Syndrome Temporally Associated With SARS-CoV-2 [PIMS-TS] in a Patient Receiving Infliximab Therapy for Inflammatory Bowel Disease

Abstract
Paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 [PIMS-TS] is a newly described condition. It has a spectrum of presentations proposed to occur as part of a post-infectious immune response. We report the first case of PIMS-TS in a child on established anti-tumour necrosis factor alpha [anti-TNFα] therapy; a 10 year-old girl with ulcerative colitis treated with infliximab. The patient had 6 weeks of daily fever with mucocutaneous, gastrointestinal, renal, and haematological involvement. Biomarkers of hyperinflammation were present including: hyperferritinaemia [up to 691 µ/L; normal 15–80 µg/L], C-reactive protein [CRP] [ &gt;100mg/L for  &gt;10 days, normal 0–5 mg/L], erythrocyte sedimentation rate [ESR] consistently  &gt;100mm/h [normal 0–15 mm/h], raised white cell count with neutrophilia, elevated D-dimer and lactate dehydrogenase [LDH], anaemia and Mott cells on bone marrow analysis. Extensive investigations for alternative diagnoses for pyrexia of unknown origin [PUO] were negative. The condition was refractory to treatment with intravenous immunoglobulin [IVIG] but improved within 24 h of high-dose methylprednisolone. Infliximab treatment followed and the patient has remained well at follow-up. Polymerase chain reaction [PCR] and serology for SARS-CoV-2 were negative. Current series report such negative findings in up to half of cases. The patient experienced a milder clinical phenotype without cardiac involvement, shock, or organ failure. Accepting the wide spectrum of PIMS-TS presentations, it is possible that previous anti-TNFα therapy may have attenuated the disease course. Given the uncertainty around therapeutic strategies for PIMS-TS, this case supports the need for further investigation into continuing infliximab as a treatment option for the condition.
Impact of water content and dietary organic carbon richness on gut bacteria in the earthwormLumbricus terrestris
Authors: Zeibich Lydia , Guhl Jennifer , Drake Harold L 
Published: September 2020

ABSTRACTMany higher and lower animal gut ecosystems have complex resident microbial communities. In contrast, ingested soil is the primary source of the gut microbial diversity of earthworms, invertebrates of fundamental importance to the terrestrial biosphere. Earthworms also harbor a few endemic bacteria including Tenericutes-affiliated Candidatus Lumbricincola of unknown function. Gut microbes are subject to nutrient fluctuations due to dilution effects during gut passage, the nutrient richness of the anoxic gut, and dietary organic carbon, factors that could alter their activity/detection. This study's objective was to assess the potential impact of these factors on the occurrence and activity of ingested and endemic bacteria in gut content of Lumbricus terrestris. Fermentation product profiles of anoxic undiluted and diluted gut content treatments were similar, suggesting that experimental increase in water content and nutrient dilution had marginal impact on fermentation. However, 16S ribosomal Ribonucleic Acid (16S rRNA) sequence abundances indicated that stimulated bacterial taxa were not identical in undiluted and diluted treatments, with dominate potentially functionally redundant phylotypes being affiliated to the Firmicutes, Fusobacteria and Proteobacteria. Although the earthworm-associated Tenericutes were not stimulated in these treatments, the occurrence of three Tenericutes-affiliated phylotypes varied with the organic carbon richness of the earthworm diet, with two phylotypes being associated with high organic carbon richness. 16S rRNA sequence abundances indicated that other dominant gut taxa also varied with dietary organic carbon richness. These findings illustrate that functionally redundant ingested bacteria and earthworm-associated Tenericutes might be influenced by nutrient fluctuations in the gut and organic carbon richness of the earthworm diet.
From Inquilines to Gall Inducers: Genomic Signature of a Life-Style Transition in Synergus Gall Wasps

Published: September 2020

Abstract
Gall wasps (Hymenoptera: Cynipidae) induce complex galls on oaks, roses, and other plants, but the mechanism of gall induction is still unknown. Here, we take a comparative genomic approach to revealing the genetic basis of gall induction. We focus on Synergus itoensis, a species that induces galls inside oak acorns. Previous studies suggested that this species evolved the ability to initiate gall formation recently, as it is deeply nested within the genus Synergus, whose members are mostly inquilines that develop inside the galls of other species. We compared the genome of S. itoensis with that of three related Synergus inquilines to identify genomic changes associated with the origin of gall induction. We used a novel Bayesian selection analysis, which accounts for branch-specific and gene-specific selection effects, to search for signatures of selection in 7,600 single-copy orthologous genes shared by the four Synergus species. We found that the terminal branch leading to S. itoensis had more genes with a significantly elevated dN/dS ratio (positive signature genes) than the other terminal branches in the tree; the S. itoensis branch also had more genes with a significantly decreased dN/dS ratio. Gene set enrichment analysis showed that the positive signature gene set of S. itoensis, unlike those of the inquiline species, is enriched in several biological process Gene Ontology terms, the most prominent of which is “Ovarian Follicle Cell Development.” Our results indicate that the origin of gall induction is associated with distinct genomic changes, and provide a good starting point for further characterization of the genes involved.
“If They Don’t Like You, They Are Not Going to Eat for You”: Individual and Interpersonal Factors Affecting Certified Nursing Assistants’ Ability to Provide Mealtime Assistance to Residents With Dementia
Authors: Douglas Joy W , Jung Seung Eun , Noh Hyunjin , Ellis Amy C , Ferguson Christine C 
Published: September 2020

Abstract

Background and Objectives
In long-term care facilities in the United States, certified nursing assistants (CNAs) provide mealtime assistance to residents with dementia, a task that substantially increases caregiver burden due to the time and attention required. The aim of this qualitative study was to explore the individual and interpersonal barriers and facilitators CNAs experience when providing mealtime assistance to residents with dementia.

Research Design and Methods
Focus group questions were developed based on the corresponding levels of the Social Ecological Model. Using purposive sampling, 9 focus groups were conducted with 53 CNAs who had at least 1 year of experience as a CNA working with older adults. Focus groups were audio-recorded and transcribed verbatim. Data were analyzed using the directed content analysis approach.

Results
CNAs reported individual skills, training, and personal characteristics that affected their ability to provide mealtime assistance. At the interpersonal level, CNAs identified their relationships with residents, residents’ family members, and other health care professionals as factors that affect their ability to provide mealtime assistance.

Discussion and Implications
These findings provide evidence for strategies that administrators can utilize to reduce caregiver burden by improving the mealtime experience. First, CNAs need adequate training, particularly to develop communication skills. Developing verbal communication skills may improve interpersonal relationships between CNAs and residents’ family members and other coworkers. Developing nonverbal communication skills may foster an improved relationship between CNAs and their residents with dementia. Future research should evaluate interventions that seek to improve these skills to determine their impact on the mealtime experience.

Published: September 2020

Abstract

Background
The health consequences of the use of Swedish snus, including its relationship with mortality, have not been fully established. We investigated the relationship between snus use and all-cause and cause-specific mortality (death due to cardiovascular diseases, cancer diseases and all other reasons, respectively) in a nationwide collaborative pooling project.

Methods
We followed 169 103 never-smoking men from eight Swedish cohort studies, recruited in 1978–2010. Shared frailty models with random effects at the study level were used in order to estimate adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) of mortality associated with snus use.

Results
Exclusive current snus users had an increased risk of all-cause mortality (aHR 1.28, 95% CI 1.20–1.35), cardiovascular mortality (aHR 1.27, 95% CI 1.15–1.41) and other cause mortality (aHR 1.37, 95% CI 1.24–1.52) compared with never-users of tobacco. The risk of cancer mortality was also increased (aHR 1.12, 95% CI 1.00–1.26). These mortality risks increased with duration of snus use, but not with weekly amount.

Conclusions
Snus use among men is associated with increased all-cause mortality, cardiovascular mortality, with death from other causes and possibly with increased cancer mortality.
Legal Expertise: A Critical Resource for Trade Unionists? Insights into the Confédération Française Démocratique du Travail
Authors: Guillaume Cécile 
Published: September 2020

Abstract
Based on in-depth qualitative research conducted in one of the major French trade unions (the CFDT), this article explores to what extent and under what conditions trade unions adopt different legal practices to further their members’ interests. In particular, it investigates how ‘legal framing’ has taken an increasingly pervasive place in trade union work, in increasingly decentralised industrial relations contexts, such as France. This article therefore argues that the use of the law has become a multifaceted and embedded repertoire of action for the CFDT in its attempt to consolidate its institutional power through various strategies, including collective redress and the use of legal expertise in collective bargaining and representation work.

Published: September 2020

Abstract
An intelligent model of the incremental capacity (IC) curve of an automotive lithium-ferrophosphate battery is presented. The relative heights of the two major peaks of the IC curve can be acquired from high-current discharges, thus enabling the state of health estimation of the battery while the vehicle is being operated and in certain cases, aging mechanisms can be suggested. Our model has been validated using a large dataset (number of batteries) representing different degradation scenarios, obtained from a recently available open-source database.
