The vibration suppression of solar panel based on smart structure
Authors: Ma G. , Xu M. , Tian J. , Kan X. 
Published: June 2020

ABSTRACTThis paper provides a solution to the active vibration control of a microsatellite with two solar panels. At first, the microsatellite is processed as a finite element model containing a rigid body and two flexible bodies, according to the principles of mechanics, and that the dynamic characteristics are solved by modal analysis. Secondly, the equation involving vibration control is established according to the finite element calculation results. There are several actuators composed of macro fibre composite on the two solar panels for outputting control force. Furthermore, the control voltage for driving actuator is calculated by using fuzzy algorithm. It is clear that the smart structure consists of the flexible bodies and actuators. Finally, the closed-loop control simulation for suppressing harmful vibration is established. The simulation results illustrate that the responses to the external excitation are decreased significantly after adopting fuzzy control.

AbstractObjective:Here, we present an overview of how a tertiary hospital responded to maintain necessary activities and protect patients and staff from the coronavirus disease (COVID-19) outbreak.Methods:Gil Medical Center, a tertiary hospital in Incheon, has operated a special response team since January 21, 2020. All visitors were assessed for body temperature and respiratory symptoms, and screened for recent overseas travel. Suspected COVID-19 patients were taken to a screening clinic. All febrile patients with or without respiratory symptoms were taken to a respiratory safety clinic. An isolation ward, which consisted of 10 negative-pressure rooms, was used to treat confirmed cases. More than 120 beds were prepared for the outbreak, and patients with pneumonia were preemptively isolated.Results:By May 5, 480 960 visitors were assessed at the control station, 3350 patients visited the triage center, and 1794 were treated in the respiratory safety clinic. Seventeen confirmed cases were admitted to the negative isolation ward, and 350 patients with pneumonia were preemptively isolated. A total of 2977 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction tests were performed.Conclusions:While tertiary hospitals play an important role in treating both COVID-19 patients and non-COVID-19 patients, hospital staff have to protect themselves from unexpected in-hospital transmission. A multifaceted response must be undertaken to protect tertiary hospitals and their staff during the COVID-19 epidemic.

We present a study of laser-driven ion acceleration with micrometre and sub-micrometre thick targets, which focuses on the enhancement of the maximum proton energy and the total number of accelerated particles at the PHELIX facility. Using laser pulses with a nanosecond temporal contrast of up to

$10^{-12}$

and an intensity of the order of

$10^{20}~\text{W}/\text{cm}^{2}$

, proton energies up to 93 MeV are achieved. Additionally, the conversion efficiency at

$45^{\circ }$

incidence angle was increased when changing the laser polarization to p, enabling similar proton energies and particle numbers as in the case of normal incidence and s-polarization, but reducing the debris on the last focusing optic.
A REFINEMENT OF THE RAMSEY HIERARCHY VIA INDESCRIBABILITY
Authors: CODY BRENT 
Published: June 2020

AbstractWe study large cardinal properties associated with Ramseyness in which homogeneous sets are demanded to satisfy various transfinite degrees of indescribability. Sharpe and Welch [25], and independently Bagaria [1], extended the notion of
$\Pi ^1_n$
-indescribability where
$n<\omega $
to that of
$\Pi ^1_\xi $
-indescribability where
$\xi \geq \omega $
. By iterating Feng’s Ramsey operator [12] on the various
$\Pi ^1_\xi $
-indescribability ideals, we obtain new large cardinal hierarchies and corresponding nonlinear increasing hierarchies of normal ideals. We provide a complete account of the containment relationships between the resulting ideals and show that the corresponding large cardinal properties yield a strict linear refinement of Feng’s original Ramsey hierarchy. We isolate Ramsey properties which provide strictly increasing hierarchies between Feng’s
$\Pi _\alpha $
-Ramsey and
$\Pi _{\alpha +1}$
-Ramsey cardinals for all odd
$\alpha <\omega $
and for all
$\omega \leq \alpha <\kappa $
. We also show that, given any ordinals
$\beta _0,\beta _1<\kappa $
the increasing chains of ideals obtained by iterating the Ramsey operator on the
$\Pi ^1_{\beta _0}$
-indescribability ideal and the
$\Pi ^1_{\beta _1}$
-indescribability ideal respectively, are eventually equal; moreover, we identify the least degree of Ramseyness at which this equality occurs. As an application of our results we show that one can characterize our new large cardinal notions and the corresponding ideals in terms of generic elementary embeddings; as a special case this yields generic embedding characterizations of
$\Pi ^1_\xi $
-indescribability and Ramseyness.

Published: June 2020

AbstractAquafeeds for carnivorous species face a nutritional–technological conundrum: containing sufficient starch to meet specific manufacturing requirements for binding, extrusion and expansion, but ideally containing as little starch as possible owing to their limited ability to utilise carbohydrates. The present study evaluated the effects of dietary starch with different amylose to amylopectin ratios and resistant starch contents on growth performance, hepatic glycogen accumulation and glucose metabolism of an important cultured carnivorous finfish, largemouth bass (Micropterus salmoides). A common starch source (α-cassava starch (CS)) was tested as is or after being enzymatically de-branched at three different inclusion levels in diets for largemouth bass. Results showed that the increased dietary starch levels compromised performance and high dietaryα-CS content led to obvious liver damage. However, the growth performances of fish fed the diets with de-branched starch (DS) were improved, and no manifest liver damages were observed even at the higher inclusion level. The increasing dietary starch contents significantly increased hepatic glycogen accumulation, but not when DS was used. High dietary starch content, without regard to starch sources, had no effect on the expression of glucose metabolism-related genes, except for down-regulation of insulin receptor expression. However, the use of dietary DS promoted the expression of genes involved in the insulin pathway and glycolysis. In conclusion, this study showed that the use of starch sources with a high amylose to amylopectin ratio and resistant starch in the feed for cultured carnivorous finfish could alleviate the hepatic glycogen deposition through regulating the insulin pathway and glycolysis.
The Spillover Effects of Hurricane Katrina on Corporate Bonds and the Choice Between Bank and Bond Financing
Authors: Massa Massimo , Zhang Lei 
Published: June 2020

AbstractWe use an exogenous event, namely, the spillover effects of Hurricane Katrina on corporate bonds through the liquidation of bond holdings by insurance companies, to study how companies react to temporary changes in the relative availability of bond and bank financing. We find that the negative shock on bonds induces firms to shift from bond financing to bank-based borrowing and to shorten the debt maturity. This shift in debt policy does not revert in the long term. There is no significant change in capital structure, suggesting that the substitution from bonds to bank loans is sufficient for the amount of borrowing.
The effectiveness of psychological interventions for post-traumatic stress disorder in children, adolescents and young adults: a systematic review and meta-analysis

Published: June 2020

AbstractBackgroundChildren and adolescents display different symptoms of post-traumatic stress disorder (PTSD) than adults. Whilst evidence for the effectiveness of psychological interventions has been synthesised for adults, this is not directly applicable to younger people. Therefore, this systematic review and meta-analysis synthesised studies investigating the effectiveness of psychological interventions for PTSD in children, adolescents and young adults. It provides an update to previous reviews investigating interventions in children and adolescents, whilst investigating young adults for the first time.MethodsWe searched published and grey literature to obtain randomised control trials assessing psychological interventions for PTSD in young people published between 2011 and 2019. Quality of studies was assessed using the Cochrane Risk of Bias tool. Data were analysed using univariate random-effects meta-analysis.ResultsFrom 15 373 records, 27 met criteria for inclusion, and 16 were eligible for meta-analysis. There was a medium pooled effect size for all psychological interventions (d= −0.44, 95% CI −0.68 to −0.20), as well as for Trauma-Focused Cognitive Behavioural Therapy (TF-CBT) and Eye Movement Desensitisation and Reprocessing (EMDR) (d= −0.30, 95% CI −0.58 to −0.02);d= −0.46, 95% CI −0.81 to −0.12).ConclusionsSome, but not all, psychological interventions commonly used to treat PTSD in adults were effective in children, adolescents and young adults. Interventions specifically adapted for younger people were also effective. Our results support the National Institute for Health and Care Excellence guidelines which suggest children and adolescents be offered TF-CBT as a first-line treatment because of a larger evidence base, despite EMDR being more effective.
Perceived neighbourhood safety and volunteerism among older adults
Authors: Grinshteyn Erin G. , Sugar Judith A. 
Published: June 2020

AbstractPrevious research shows the benefits of volunteerism to individuals and communities. The purpose of this study was to determine whether lower perceived neighbourhood safety is associated with reduced volunteerism and whether this association differs by sex. Data from the 2008 Health and Retirement Study in the United States of America were used (N = 13,009 adults 60 years and older). Multivariate logistic regression models were estimated to assess the association between perceived neighbourhood safety and volunteerism while controlling for potential confounders. Perceived neighbourhood safety was associated with volunteering. The odds of volunteering were higher for those rating their perceived neighbourhood safety as excellent compared with those rating their perceived neighbourhood safety as fair/poor. Those rating their perceived neighbourhood safety as very good also had greater odds of volunteering than those rating their perceived neighbourhood safety as fair/poor. Results differed somewhat by gender. Men who perceived their neighbourhood safety as excellent had increased odds of volunteering. The association of neighbourhood safety with volunteerism was significant for women rating their perceived neighbourhood safety as excellent or very good. Among men, being married was associated with increased odds of volunteering; being completely or partly retired was associated with increased odds of volunteering among women. Initiatives aimed at improving older adults’ perceptions of safety would help improve volunteerism, which is beneficial to both older adults and communities.

Published: June 2020

SUMMARYIn brachytherapy, the manual implantation of seeds is not accurate leading to side effects and limiting the use of new procedures. Robotics solutions have to be fully suitable for medical applications especially considering the operating room. This paper investigates a delta robot solution for improving the accuracy of the prostate brachytherapy procedure by proposing a compact and lightweight robot. In addition, the design was thought as a comanipulated robot for a better acceptability and human–machine interaction. The robot kinematics and singularities were determined and the theoretical capability in term of resolution and force feedback was evaluated. A prototype was built in order to experimentally measure the capability of this first prototype.
“Fractured Resemblances”: Contested Multinational Heritage and Soft Power
Authors: Sargent Sarah 
Published: June 2020

Abstract:Intangible cultural heritage elements are shared across state borders. In many instances, states join in multinational nominations to inscribe the heritage element in a way that reflects this reality. But, at times, states are unwilling or unable to cooperate in a mutual nomination that reflects the shared nature of the heritage element. The consequence of this is that heritage elements can then be nominated by individual states without any reflection of the multinational or cross-border nature of the element; thus leaving the heritage elements shorn of this aspect of their nature. The current international heritage legal regime, through the United Nations Educational, Scientific and Cultural Organization, does not adequately acknowledge or address this problem. This article, through a case study of the successful nomination by Azerbaijan of the horseback game ofchovqan, examines the causes and consequences of these “fractured resemblances.” It analyzes the links between cultural heritage, conflict, and the use of heritage as a form of soft power. It focuses on the use of single-state inscription as a soft-power means of obtaining international prestige and support and the resultant effects on shared cultural heritage elements. From this, suggestions for changes to international heritage laws for the inscription of cultural heritage are suggested to accommodate the reality of the connection between cultural heritage, conflict, and power and to avoid the occurrence of “fractured resemblances” of heritage shared across state lines.

Abstract
The majority of available US-published reports present populations with community spread in urban areas. The objective of this report is to describe a rural healthcare system's utilisation of therapeutic options available to treat Coronavirus Disease 2019 (COVID-19) and subsequent patient outcomes. A total of 150 patients were treated for COVID-19 at three hospitals in the Dakotas from 21 March 2020 to 30 April 2020. The most common pharmacological treatment regimens administered were zinc, hydroxychloroquine plus azithromycin and convalescent plasma. Adjunctive treatments included therapeutic anticoagulation, tocilizumab and corticosteroids. As of 1 June 2020, 127 patients have survived to hospital discharge, 12 patients remain hospitalised and 11 patients have expired. The efficacy of hydroxychloroquine and azithromycin use has yet to be determined but was not without risks of corrected QT interval prolongation and arrhythmias in our cohort. We did not appreciate any adverse effects that appeared related to tocilizumab or convalescent plasma administration in those patient subsets. These findings may provide insight into disease severity and treatment options in the rural setting with limited resources to participate in clinical trials and encourage larger comparative studies evaluating treatment efficacy.
THE HOUSEHOLD FUNCTIONS OF OBSIDIAN TOOLS FROM THE EARLY–MIDDLE FORMATIVE VILLAGE OF ALTICA, MEXICO
Authors: Walton David P. 
Published: June 2020

AbstractFunctional determinations of stone tools gleaned through high-magnification usewear analysis enable archaeologists to reconstruct ancient household practices and identify diversity across regional domestic economies. A systematic obsidian usewear study with 300 specimens from the site of Altica, Mexico presented here reveals that tools from the Early–Middle Formative (1250–800 cal.b.c.) occupation were used for woodworking and subsistence-related activities. The high frequency of woodworking usewear patterns can be attributed to the construction and maintenance of the newly established settlement's households and agricultural plots. Combined with previous analyses of the site's paleoethnobotanical, osteological, and isotopic datasets, the usewear data further indicate a subsistence strategy that balanced foraging and non-intensive maize agriculture. Thanks to their proximity to the Otumba source and other sites exploiting it, Altica residents were able to employ a unifunctional tool-use approach with expedient percussion tools, which contrasts the multifunctional tool-use approaches documented at other Middle Formative sites.
A primer on artificial intelligence for the paediatric cardiologist
Authors: Gearhart Addison , Gaffar Sharib , Chang Anthony C. 
Published: June 2020

AbstractThe combination of pediatric cardiology being both a perceptual and a cognitive subspecialty demands a complex decision-making model which makes artificial intelligence a particularly attractive technology with great potential. The prototypical artificial intelligence system would autonomously impute patient data into a collaborative database that stores, syncs, interprets and ultimately classifies the patient’s profile to specific disease phenotypes to compare against a large aggregate of shared peer health data and outcomes, the current medical body of literature and ongoing trials to offer morbidity and mortality prediction, drug therapy options targeted to each patient’s genetic profile, tailored surgical plans and recommendations for timing of sequential imaging. The focus of this review paper is to offer a primer on artificial intelligence and paediatric cardiology by briefly discussing the history of artificial intelligence in medicine, modern and future applications in adult and paediatric cardiology across selected concentrations, and current barriers to implementation of these technologies.
Household fuelwood consumption in western rural China: ethnic minority families versus Han Chinese families
Authors: Yang Xiaojun , Li Jun , Xu Jintao , Yi Yuanyuan 
Published: June 2020

AbstractThis paper examines ethnic differences in fuelwood consumption in rural households, using an original survey dataset from two western Chinese provinces with large ethnic minority populations. We use a Heckman two-stage selection model to explain the quantity of fuelwood consumed conditional on a decision to use fuelwood. We find that ethnic minority families are more likely than majority Han Chinese families to use fuelwood. We also find that a household's off-farm income has a stronger negative effect on the quantity of fuelwood consumed for the ethnic minority families than for the Han Chinese families. In addition, families owning a larger area of forestland are more likely to use fuelwood. Yet the quantity of fuelwood consumed, especially in ethnic minority families, does not increase with owned forestland. Finally, we find that coal, rather than electricity, is a substitute for fuelwood for residential cooking and heating.

Published: June 2020

Zusammenfassung. Die vorliegende Studie befasst sich mit der Übersetzung und Validierung des englischsprachigen Sport Emotion Questionnaire (SEQ; Jones et al., 2005 ), der vorwettbewerblichen Emotionen von Sporttreibenden misst. In einer ersten Teilstudie wurde mittels einer Hin-Rück-Übersetzung und des Bilingual-Retest-Verfahrens ( n = 32) eine deutsche Version des SEQ (SEQ-d) erzeugt. In Studie 2 (Tennisspieler/innen, n = 116) zeigte sich jedoch eine vom Original abweichende Faktorstruktur, woraufhin der SEQ-d als dreidimensionale Kurzskala entwickelt wurde. Diese wurde in Studie 3 (Läufern/innen, n = 271) validiert. Die Kurzskala besitzt einen akzeptablen Fit (CFI = .950, RMSEA = .069, SRMR = .063) und eine interne Konsistenz von α = .84 (negative Emotionen), α = .86 (positive Emotionen), α = .87 (Anspannung). Durch Korrelationen mit anderen Emotionsmerkmalen konnte die konvergente Validität bestätigt werden. Die Kriteriumsvalidität wurde anhand wettkampf- und personenbezogener Zusatzparameter untersucht (bspw. Alter, Wettkampferfahrung…). Mit der deutschsprachigen Version des SEQ liegt ein ökonomisches und validiertes Messinstrument zur Erfassung vorwettbewerblicher Emotionen vor.
PV‐Q Perspective of Cyclogenesis and Vertical Velocity Development Downstream of the Tibetan Plateau

Published: June 2020

AbstractThis study reviews the development of the omega equation and the relation between omega and potential vorticity (PV) advection and considers the application of PV theory to investigate the impact of large‐scale mountains on downstream weather development. A diabatic quasi‐geostrophic omega equation is introduced to reveal the feedback of diabatic heating (Q) on PV advection and vertical velocity. A challenge therein concerning the use of the diagnostic omega equation to interpret weather system development is considered from the PV‐Q perspective based on a severe weather event that occurred downstream of the Tibetan Plateau (TP) on 17–21 January 2008. Results demonstrate that owing to PV restructuring, positive PV was generated over the eastern flank of the TP, and its eastward advection triggered development of isentropic displacement vertical velocity and cyclogenesis in the lower troposphere. A converging southeasterly wind accompanied with ascending isentropic gliding vertical velocity in the lower troposphere was induced to the east of the cyclone center, which transported not only warm moist air but also negative PV from the south, contributing to developments of both local diabatic ascent and precipitation and eastward migration of the cyclone. During the cyclone life cycle, three omega components induced by different processes interacted with each other, and diabatic heating associated with precipitation exerted considerable feedback to vertical motion as well as PV advection. It is the vertical differential PV advection and feedback from diabatic heating that control the evolution of the circulation and the associated precipitation downstream of the TP.
