Published: June 2020

AbstractConsistent among-individual variation in behavior, or animal personality, is present in a wide variety of species. This behavioral variation is maintained by both genetic and environmental factors. Parental effects are a special case of environmental variation and are expected to evolve in populations experiencing large fluctuations in their environment. They represent a non-genetic pathway by which parents can transmit information to their offspring, by modulating their personality. While it is expected that parental effects contribute to the observed personality variation, this has rarely been studied in wild populations. We used the multimammate mouse Mastomys natalensis as a model system to investigate the potential effects of maternal personality on offspring behavior. We did this by repeatedly recording the behavior of individually housed juveniles which were born and raised in the lab from wild caught females. A linear correlation, between mother and offspring in behavior, would be expected when the personality is only affected by additive genetic variation, while a more complex relationship would suggests the presence of maternal effects. We found that the personality of the mother predicted the behavior of their offspring in a non-linear pattern. Exploration behavior of mother and offspring was positively correlated, but only for slow and average exploring mothers, while this correlation became negative for fast exploring mothers. This may suggests that early maternal effects could affect personality in juvenile M. natalensis, potentially due to density-dependent and negative frequency-dependent mechanisms, and therefore contribute to the maintenance of personality variation.

Summary
The ECCG developed a standardized platform for reporting operative complications, with consensus definitions. The Dutch Upper Gastrointestinal Cancer Audit (DUCA) published a national comparison against these benchmarks. This study compares ECCG data from the Irish National Center (INC) with both published benchmark studies. All patients undergoing multimodal therapy or surgery with curative intent from 2014 to 2018 inclusive were studied, with data recorded prospectively and entered onto a secure online database (Esodata.org). 219 patients (mean age 67; 77% male) underwent open resection, 66.6% via transthoracic en bloc resection. 30-day and 90-day mortality were 0.0 and 0.9%,nrespectively. Anastomotic leak rate was 5.4%, pneumonia 18.2%, respiratory failure 10%, ARDS 2.7%, atrial dysrhythmia 22.8%, recurrent nerve injury 3%, and delirium in 5% of patients. Compared with both ECCG and DUCA, where MIE constituted 47 and 86% of surgical approaches, respectively, overall complications were similar, as were severity of complications; however, anastomotic leak rate was several-fold less, and mortality was significantly lower (P &lt; 0.001). In this consecutive series and comparative audit with benchmark averages from the ECCG and DUCA publications, a low mortality and anastomotic leak rate were the key differential findings. Although not risk stratified, the severity of complications from this ‘open’ series is consistent with series containing large numbers of total or hybrid MIE, highlighting a need to adhere to these strictly defined definitions in further prospective research and randomized studies.
Current options and recommendations for the use of thoracic endovascular aortic repair in acute and chronic thoracic aortic disease: an expert consensus document of the European Society for Cardiology (ESC) Working Group of Cardiovascular Surgery, the ESC Working Group on Aorta and Peripheral Vascular Diseases, the European Association of Percutaneous Cardiovascular Interventions (EAPCI) of the ESC and the European Association for Cardio-Thoracic Surgery (EACTS)

Abstract
Since its clinical implementation in the late nineties, thoracic endovascular aortic repair (TEVAR) has become the standard treatment of several acute and chronic diseases of the thoracic aorta. While TEVAR has been embraced by many, this disruptive technology has also stimulated the continuing evolution of open surgery, which became even more important as late TEVAR failures do need open surgical correction justifying the need to unite both treatment options under one umbrella. This fact shows the importance of—in analogy to the heart team—aortic centre formation and centralization of care, which stimulates continuing development and improves outcome . The next frontier to be explored is the most proximal component of the aorta—the aortic root, in particular in acute type A aortic dissection—which remains the main challenge for the years to come. The aim of this document is to provide the reader with a synopsis of current evidence regarding the use or non-use of TEVAR in acute and chronic thoracic aortic disease, to share latest recommendations for a modified terminology and for reporting standards and finally to provide a glimpse into future developments.
Lions, tigers and kittens too: ACE2 and susceptibility to COVID-19
Authors: Mathavarajah Sabateeshan , Dellaire Graham 
Published: June 2020

Abstract
SARS-CoV-2 (Severe Acute Respiratory Syndrome coronavirus 2) has been reported to infect domesticated animals in a species-specific manner, where cats were susceptible but not dogs. Using the recently published crystal structure of the SARS-CoV-2 spike protein complexed with the human host cell receptor angiotensin converting enzyme 2 (ACE2), we characterized the structure and evolution of ACE2 in several of these species and identify a single interacting amino acid residue conserved between human and Felidae ACE2 but not in Canidae that correlates with virus susceptibility. Using computational analyses we describe how this site likely affects ACE2 targeting by the virus. Thus, we highlight how evolution-based approaches can be used to form hypotheses and study animal transmission of such viruses in the future.
Measuring Senior Technology Acceptance: Development of a Brief, 14-Item Scale
Authors: Chen Ke , Lou Vivian Wei Qun 
Published: June 2020

AbstractBackground and ObjectivesTechnology has the potential to provide assistance and enrichment to older people; however, the desired outcomes are dependent on users’ acceptance and usage. The senior technology acceptance model (STAM) was developed as a multidimensional measure assessing older people’s acceptance of general technology. It contained 11 constructs measured by 38 items and had shown satisfactory psychometric properties. However, the length of the questionnaire increased respondent burden and limited its utilization. The study aimed to develop a brief, reliable, and valid version of scale to measure older people’s technology acceptance by shortening the full, 38-item STAM questionnaire.Research Design and MethodsThe research method included (1) a sequential item-reduction strategy maximizing internal consistency, (2) convergent and discriminant validity analysis based on confirmative factor analysis, and (3) an expert review of resultant items. Data previously collected for developing the original STAM questionnaire were used to create the brief version. The data were collected from 1,012 community-dwelling individuals aged 55 and older in Hong Kong. Internal consistency and construct validity of the shortened questionnaire were examined. Two experts were invited for reviewing content validity.ResultsThe final 14-item, brief version of the STAM questionnaire consisted of a 4-factor structure, representing classical technology acceptance constructs and age-related health characteristics. Theoretical relationships in the brief version showed similar patterns to the original STAM. The 14-item STAM demonstrated robustness in psychometrics by preserving the reliability and validity of the original STAM questionnaire.Discussion and ImplicationsThe availability of a reliable and valid assessment tool of the short STAM can help researchers and practitioners to measure older adults’ acceptance of technology and its effective usage. The short STAM could save administration time, reduce the burden on respondents, and be included in large-scale surveys.
Patterns of Dyadic Appraisal of Decision-Making Involvement of African American Persons Living With Dementia
Authors: Bonds Kalisha , Song MinKyoung , Whitlatch Carol J , Lyons Karen S , Kaye Jeffrey A , Lee Christopher S 
Published: June 2020

Abstract

Background and Objectives
Greater everyday decision-making involvement by persons living with dementia (PLWD) and congruent appraisal between PLWDs and their caregivers have been associated with a better quality of life (QOL) for both members of the dyad. However, no study has examined the association between the appraisals of everyday decision-making involvement of PLWDs and their QOL among African Americans.

Research Design and Methods
A secondary analysis of cross-sectional data from 62 African American dementia dyads was conducted. Multilevel and latent class mixture modeling was used to characterize dyadic appraisal of the decision-making involvement of African American PLWDs and identify distinct patterns thereof.

Results
Three distinct patterns were observed. “Incongruent, PLWD Low Involvement” labeled 19.4% of the sample, 53.2% were labeled “Incongruent, PLWD Moderate Involvement,” and 27.4% were labeled “Congruent, PLWD High Involvement.” The Congruent, PLWD High Involvement pattern consisted of PLWDs who were significantly younger and had significantly less cognitive impairment than PLWDs in the other patterns. In the Incongruent, PLWD Moderate Involvement pattern, PLWDs had significantly better QOL than PLWDs in the Incongruent, PLWD Low Involvement pattern, but QOL did not significantly differ from PLWDs in the Congruent, PLWD High Involvement pattern.

Discussion and Implications
There is a need to tailor strategies to optimize QOL in African American dementia dyads. While increasing everyday decision-making involvement for PLWDs in the Incongruent, PLWD Low Involvement pattern is an important goal, other strategies may be needed to improve the QOL of PLWDs in the remaining patterns.

Abstract
Effective obesity interventions in adolescent populations have been identified as an immediate priority action to stem the increasing prevalence of adult obesity. The purpose of this meta-analysis was to make a quantitative analysis of the impact of school-based interventions on body mass index during adolescence. Studies were retrieved from PubMed, Scopus, Science Direct and Web of Science databases. Results were pooled using a random-effects model with 95% confidence interval considered statistically significant. Of the 18 798 possible relevant articles identified, 12 articles were included in this meta-analysis. The global result showed a low magnitude effect, though it was statistically significant (N = 14 428), global e.s. = −0.055, P = 0.004 (95% CI = −0.092, −0.017). Heterogeneity was low among the studies (I2 = 9.017%). The funnel plot showed no evidence of publication bias. The rank-correlation test of Begg (P = 0.45641) and Egger’s regression (P = 0.19459) confirmed the absence of bias. This meta-analysis reported a significant effect favoring the interventions; however, future research are needed since the reported the evidence was of low magnitude, with the studies following a substantial range of approaches and mostly had a modest methodological quality.
Do children’s expectations about future physical activity predict their physical activity in adulthood?
Authors: Pongiglione Benedetta , Kern Margaret L , Carpentieri J D , Schwartz H Andrew , Gupta Neelaabh , Goodman Alissa 
Published: June 2020

Abstract

Background
Much of the population fails to meet recommended physical activity (PA) levels, but there remains considerable individual variation. By understanding drivers of different trajectories, interventions can be better targeted and more effective. One such driver may be a person’s physical activity identity (PAI)—the extent to which a person perceives PA as central to who they are.

Methods
Using survey information and a unique body of essays written at age 11 from the National Child Development Study (N = 10 500), essays mentioning PA were automatically identified using the machine learning technique support vector classification and PA trajectories were estimated using latent class analysis. Analyses tested the extent to which childhood PAI correlated with activity levels from age 23 through 55 and with trajectories across adulthood.

Results
42.2% of males and 33.5% of females mentioned PA in their essays, describing active and/or passive engagement. Active PAI in childhood was correlated with higher levels of activity for men but not women, and was correlated with consistently active PA trajectories for both genders. Passive PAI was not related to PA for either gender.

Conclusions
This study offers a novel approach for analysing large qualitative datasets to assess identity and behaviours. Findings suggest that at as young as 11 years old, the way a young person conceptualizes activity as part of their identity has a lasting association with behaviour. Still, an active identity may require a supportive sociocultural context to manifest in subsequent behaviour.
Finiteness Properties of Affine Difference Algebraic Groups
Authors: Wibmer Michael 
Published: June 2020

Abstract
We establish several finiteness properties of groups defined by algebraic difference equations. One of our main results is that a subgroup of the general linear group defined by possibly infinitely many algebraic difference equations in the matrix entries can indeed be defined by finitely many such equations. As an application, we show that the difference ideal of all difference algebraic relations among the solutions of a linear differential equation is finitely generated.
Asymptotics for the Nodal Components of Non-Identically Distributed Monochromatic Random Waves
Authors: Enciso Alberto , Peralta-Salas Daniel , Romaniega Álvaro 
Published: June 2020

Abstract
We study monochromatic random waves on ${\mathbb{R}}^n$ defined by Gaussian variables whose variances tend to zero sufficiently fast. This has the effect that the Fourier transform of the monochromatic wave is an absolutely continuous measure on the sphere with a suitably smooth density, which connects the problem with the scattering regime of monochromatic waves. In this setting, we compute the asymptotic distribution of the nodal components of random monochromatic waves, showing that the number of nodal components contained in a large ball $B_R$ grows asymptotically like $R/\pi $ with probability $p_n&gt;0$ and is bounded uniformly in $R$ with probability $1-p_n$ (which is positive if and only if $n\geqslant 3$). In the latter case, we show the existence of a unique noncompact nodal component. We also provide an explicit sufficient stability criterion to ascertain when a more general Gaussian probability distribution has the same asymptotic nodal distribution law.
Epstein-Barr Virus-Based Nasopharyngeal Carcinoma (NPC) Risk Prediction Scores Are Elevated in NPC Multiplex Family Members in Taiwan

Abstract
Nasopharyngeal carcinoma (NPC) is caused by Epstein-Barr virus (EBV) and is more likely to occur in susceptible families. Whether genetic susceptibility operates through altered EBV control is incompletely understood. We used a NPC risk prediction model based on 14 EBV markers to compare risk score distribution in unaffected members from multiplex families with that in population-based controls. Despite the absence of NPC at the time of antibody measurement, we observed an upward shift in risk score among multiplex family members compared to the general population, consistent with the possibility that genetic factors affect NPC risk through alterations in EBV control.

Abstract

Introduction
Ultrasound is now recognized as a key tool in the practice of medicine in isolated situations. This study aims to evaluate the impact of transthoracic echocardiography (TTE) in a military mission when performed by a trained military practitioner (MP).

Materials and Methods
We conducted a 2-month retrospective observational study on the use of TTE in a French medical complex in Mali with a mission that included providing a medical aid to the population. All patients were included. Every ultrasound performed by the MP was listed, and the epidemiologic data, indication for the exam and results were collected for each TTE.

Results
A total of 349 patients were included, 16 were war-wounded patients and 333 came for a general medical consultation. In all, 153 ultrasounds were performed, including 48 TTEs. Sixteen TTEs were performed to evaluate injuries in war-wounded patients. During the 333 medical consultations, 32 TTEs were realized. The indications were dyspnoea (10), heart murmur (7), acute chest pain (5) and assessment of heart disease (10). TTE permitted a direct positive diagnosis for 18 patients: 7 with acute heart failure and 11 with morphologic problems. The normality of the exam was a supplementary argument to exclude a cardiac implication for eight patients.

Conclusions
TTE can provide important information with a direct impact on the management of patients. Faced with cardiac emergencies, an adapted training can be proposed for the MP. Thereby, the transfer of conventional cardiac views could facilitate the advice of a cardiologist.
Horseshoe co-orbitals of Earth: current population and new candidates
Authors: Kaplan Murat , Cengiz Sergen 
Published: June 2020

ABSTRACT
Most co-orbital objects in the Solar system are thought to follow tadpole-type orbits, behaving as Trojans. However, most of Earth’s identified co-orbitals are moving along horseshoe-type orbits. The current tally of minor bodies considered to be Earth co-orbitals amounts to 18; of them, 12 are horseshoes, 5 are quasi-satellites, and 1 is a Trojan. The semimajor axis values of all these bodies librate between 0.983 and 1.017 au. In this work, we have studied the dynamical behaviour of objects following orbits with semimajor axis within this range that may be in a 1:1 mean-motion resonance with Earth. Our results show that asteroids 2016 CO246, 2017 SL16, and 2017 XQ60 are moving along asymmetrical horseshoe-type orbits; the asteroid 2018 PN22 follows a nearly symmetric or regular horseshoe-type orbit. Asteroids 2016 CO246, 2017 SL16, and 2017 XQ60 can remain in the horseshoe co-orbital state for about 900, 3300, and 2700 yr, respectively. Asteroid 2018 PN22 has a more chaotic dynamical behaviour; it may not stay in a horseshoe co-orbital state for more than 200 yr. The horseshoe libration periods of 2016 CO246, 2017 SL16, 2017 XQ60, and 2018 PN22 are 280, 255, 411, and 125 yr, respectively.
New insight into the origin of the GeV flare in the binary system PSR B1259-63/LS 2883 from the 2017 periastron passage

Published: June 2020

ABSTRACT
PSR B1259-63 is a gamma-ray binary system hosting a radio pulsar orbiting around an O9.5Ve star, LS 2883, with a period of ∼3.4 yr. The interaction of the pulsar wind with the LS 2883 outflow leads to unpulsed broad-band emission in the radio, X-rays, GeV, and TeV domains. While the radio, X-ray, and TeV light curves show rather similar behaviour, the GeV light curve appears very different with a huge outburst about a month after a periastron. The energy release during this outburst seems to significantly exceed the spin-down luminosity of the pulsar and both the GeV light curve and the energy release vary from one orbit to the next. In this paper, we present for the first time the results of optical observations of the system in 2017, and also reanalyse the available X-ray and GeV data. We present a new model in which the GeV data are explained as a combination of the bremsstrahlung and inverse Compton emission from the unshocked and weakly shocked electrons of the pulsar wind. The X-ray and TeV emission is produced by synchrotron and inverse Compton emission of energetic electrons accelerated on a strong shock arising due to stellar/pulsar winds collision. The brightness of the GeV flare is explained in our model as a beaming effect of the energy released in a cone oriented, during the time of the flare, in the direction of the observer.
Wide binaries are rare in open clusters
Authors: Deacon N R , Kraus A L 
Published: June 2020

ABSTRACT
The population statistics of binary stars are an important output of star formation models. However, populations of wide binaries evolve over time due to interactions within a system’s birth environment and the unfolding of wide, hierarchical triple systems. Hence, the wide binary populations observed in star-forming regions or OB associations may not accurately reflect the wide binary populations that will eventually reach the field. We use Gaia DR2 data to select members of three open clusters, Alpha Per, the Pleiades, and Praesepe and to flag cluster members that are likely unresolved binaries due to overluminosity or elevated astrometric noise. We then identify the resolved wide binary population in each cluster, separating it from coincident pairings of unrelated cluster members. We find that these clusters have an average wide binary fraction in the 300–3000 au projected separation range of 2.1$\pm ^{0.4}_{0.2}$ per cent increasing to 3.0$\pm ^{0.8}_{0.7}$ per cent for primaries with masses in the 0.5–1.5 M⊙ range. This is significantly below the observed field wide binary fraction, but shows some wide binaries survive in these dynamically highly processed environments. We compare our results with another open cluster (the Hyades) and two populations of young stars that likely originated in looser associations (young moving groups and the Pisces-Eridanus stream). We find that the Hyades also has a deficit of wide binaries while the products of looser associations have wide binary fractions at or above field level.
Cooling of hybrid neutron stars with microscopic equations of state

Published: June 2020

ABSTRACT
We model the cooling of hybrid neutron stars combining a microscopic nuclear equation of state in the Brueckner–Hartree–Fock approach with different quark models. We then analyse the neutron star cooling curves predicted by the different models and single out the preferred ones. We find that the possibility of neutron p-wave pairing can be excluded in our scenario.
