Published: July 2020

ABSTRACT
Perturbation of spectrin-based membrane mechanics causes hereditary elliptocytosis and spinocerebellar ataxia, but the underlying cellular basis of pathogenesis remains unclear. Here, we introduced conserved disease-associated spectrin mutations into the Caenorhabditis elegans genome and studied the contribution of spectrin to neuronal migration and dendrite formation in developing larvae. The loss of spectrin resulted in ectopic actin polymerization outside of the existing front and secondary membrane protrusions, leading to defective neuronal positioning and dendrite morphology in adult animals. Spectrin accumulated in the lateral region and rear of migrating neuroblasts and redistributes from the soma into the newly formed dendrites, indicating that the spectrin-based membrane skeleton is asymmetric and remodels to regulate actin assembly and cell shape during development. We affinity-purified spectrin from C. elegans and showed that its binding partner ankyrin functions with spectrin. Asymmetry and remodeling of the membrane skeleton might enable spatiotemporal modulation of membrane mechanics for distinct developmental events.

Published: July 2020

Background: Picralima nitida (Apocynaceae) is an important African medicinal plant species. It is frequently used in traditional medicine and pharmaceutical industries for manufacture of drugs against infectious diseases, malaria, diabetes and cancer. Despite its important, the species can be rare, especially in the Dahomey Gap (in contrast to the Guineo-Congolese region). There is also a controversy on its distribution. To ensure the sustainable use of the species, this study evaluated the economic value, endogenous knowledge and effect of climate gradient on the distribution of the species in Africa. Methods: Ethnobotanical surveys were conducted in the Dahomey Gap with 120 informants randomly interviewed. A literature review of scientific papers and books was used to provide information on the uses, distribution and threats of the species in the Guineo-Congolese region. Results: The results revealed that P. nitida products were more expensive in the Dahomey Gap than the Guineo-Congolese region. All parts of the species were collected and used for 34 treatments. The species had low density and distribution in Dahomey Gap compared to the Guineo-Congolese region. Conclusions: P. nitida is used across its distribution areas with important economic values. Adapted management strategies are needed for the sustainable use and conservation of the species.

COMSOL Multiphysics was employed to establish a dislocation model based
on the Alexander and Haasen (AH) model, the heat conduction equation,
and Hooke’s law for calculating the dislocation distribution of
germanium (Ge) under laser irradiation. The numerical simulation
results were obtained. A continuous 1080 nm laser was utilized to
ablate the monocrystalline Ge wafers to validate the model. The
experimental results show that no surface damage appears until the
irradiances go up to

First Report of Scoters (<i>Melanitta</i> spp.) along Eastern Baffin Island, Nunavut, Canada
Authors: Mallory Mark M. , Chardine John , Gilliland Scott 
Published: July 2020

In September of 2017 and 2018, we observed hundreds of scoters (Melanitta spp.) in fiords in Arctic Canada, approximately 1100 – 1800 km north of their previous northernmost observations. Given the remote locations and timing of observations, we do not know if these represent previously undiscovered areas where birds moult or new movements to Arctic locations. Moreover, the provenance of these sea ducks is unclear, as no evidence of movements to this region was indicated by large-scale satellite tracking of North American scoters during the last decade.

Published: July 2020

The circumpolar Arctic ringed seal (Pusa hispida) occupies its fast-ice breeding habitat for four to five months during winter and the pack ice or open water of adjacent areas for the rest of the year. From 1971 – 78 and 1992 – 2019, we sampled approximately 100 ringed seals annually from western Prince Albert Sound (WPAS), the prime ringed seal fast-ice breeding habitat in Canada’s Western Arctic, adjacent to primary overwinter foraging habitat in eastern Amundsen Gulf (EAG). As our metric of body condition, we measured ventral blubber depth corrected for body size. As our metrics of reproduction, we measured the annual ovulation rate of multiparous females and percent pups in the open-water harvest. We examined these biological parameters in relation to the winter Arctic Oscillation Index (winAOI) and the timing of sea ice clearance in EAG in spring. There were no significant effects of age or sample month (June or July) on adult blubber depth, but significant sex and year effects and, in females, ovulation status effects. Across the series, as we have observed previously through 2011, there was a sustained temporal declining trend in blubber depth in adults of both sexes. There was no temporal trend in residual blubber depth, no correlation between blubber depth and sea ice clearance date in EAG, and a quasi-cyclic pattern in blubber depth that tracked some of the phases of the winAOI. Annual ovulation rates were mainly in the 80% – 100% range and correlated with percent pups in the open harvest in the same year. Three (1974, 2005, 2012) of the 36 y experienced reproductive failures, when over 50% of the multiparous females failed to ovulate. In each case, ovulation rates returned to normal within 1 – 3 y. Low annual ovulation rates were correlated with late sea ice clearance in EAG in spring, with two widespread ovulation failure events taking place in years when spring sea ice clearance was delayed by five to six weeks. The most recent ovulation failure (2012) differed in that it came in an average ice year but at the end of a six-year sequence of negative residual mean blubber depths. Earlier spring sea ice clearance in WPAS, based on the observed rate of 3.8 d per decade, would on average not result in the physical loss of sea ice for pupping in this core habitat before 2140. The mechanisms involved in the sustained declining temporal trend in body condition, linkage with some phases of the winAOI, and the temporary but episodic failures of ovulation are complex and not fully explained by either the timing of sea ice clearance or the winAOI. Until the complex mix of factors, pressures and responses are understood, our ability to predict the impacts of a changing climate on ringed seals will remain limited.

Published: July 2020

La segunda y tercera bienales internacionales de arte de Coltejer, celebradas en Medellín en 1970 y 1972, constituyen los más importantes eventos de arte de vanguardia de esa década en Colombia. La calidad y afluencia de los artistas internacionales invitados -nunca antes habían sido tantos ni de tan alta valía- no volverá a verse ni en esa década ni en la siguiente en Colombia hasta el actual mileno. Este texto sitúa los debates alrededor de la obra Piedra, de Carlos Ginzburg, presentada en la Bienal de 1972. Esta obra nos sirve como prisma para examinar las condiciones, logros y aciertos de estos eventos -cuya historia no ha sido contada- y los debates y fricciones que contribuyeron a su temprano fin.
The Impact of Audit Committees on the Realization of an Integration Relationship between Internal and External Audit when Conducting Audits. A Study on Public Shareholding Corporations
Authors: KHERSIAT Ola Mohammad 
Published: July 2020

This study aims to investigate methods of achieving an integrating relationship between internal and external audit when conducting audit procedures in Jordanian public shareholding corporations, as well as investigate the impact of audit committees achieving such a relationship since an effective internal audit effective the external auditor`s estimations regarding control risks. The study concludes that all aspects of the realization of an integration relation between internal and external audit have achieved a fair ratio exceeding 60%. Spearman test was used to show the nature of the relationship between the internal and external audit. The test results showed that the relationship between these methods is vulnerable in Jordanian public shareholding corporations, and that audit committees have no statistically significant impact on achieving an integrating relationship between internal and external audits in conducting audit in Jordanian public shareholding corporations, since the ratio of audit committees interpretation (R2) which amounted to (.145) of the dependent variable difference ( achieving an integrating relationship between internal and external audit in conducting audit) is relatively low, and that the P- value derived for this relation amounted to (.615) which is more than (5%) .
Formation of Mass Media Law in the Post-Soviet Russia: Constitutional Foundations and Stages

Published: July 2020

Today, countries are developing new forms of interaction between state and mass media and expanding their regulatory frameworks. In several states, specific integrated institutes and legal sectors have been formed that regulate the legal status of mass media.
Since the early 1990s, the Russian Federation has been working on special rules governing the constitutional status of mass media. During this period, a comprehensive media institute formed in the framework of information law, which later transformed into mass media law. The evolution of this institute is of particular scientific interest, as Russia did not have any law on mass media until the end of the 20th century.
Cross Border M&A’s in ASEAN and India: A Comparative Critique
Authors: TIWARI Avin , SHUKLA Gaurav , PANDEY Suesh Kumar 
Published: July 2020

Cross-border merger and acquisitions (hereinafter, M&A’s) have increased exponentially in Asia since the mid-1990s due to the liberalization of the economy, the deregulation of the service sector, privatization of state-owned public enterprises, and the relaxation of regulatory controls over cross-border M&A's. ASEAN economies and India are significant players in the global arena for cross-border M&A's, and thus, their importance cannot be undermined. Cross-border M&A's have distinctive implications on the socio-economic scenario of a Nation, and most importantly, it impacts substantial change in legal dimensions, involving compliance requirements, acquisition procedures, and tax liabilities.
The present study is a doctrinal one; the primary objective being, a legislative frame analysis of select ASEAN countries and India with regards to cross-border M&A’s. The top five ASEAN countries, viz., Indonesia, Malaysia, the Philippines, Singapore, and Thailand were selected on account of the cross-border trade volume over the past decade. The authors applied comparative and analytical methods to pursue the research inquiry. The second objective was to ascertain the vital macro-economic factors playing a decisive role in the outcome of cross-border M&A’s in the select region. Here the authors highlighted the relationship between certain macro-economic factors like trade openness, financial integration, increased inflation, increased GDP, etc. which positively impact M&As. The third and final objective was to analyze the trends of cross border M&A’s in the select region for the past decade, i.e. 2008 to 2018, as this period perfectly encapsulates a complete economic cycle from depression to boom alongside major legal developments in the field of cross-border M&A’s around the world. Furthermore, while undergoing the study, the authors highlighted certain risk factors in terms of competition, transaction, and people with regards to cross border M&A’s in the select region. Findings from the study indicated that ASEAN economies have little experience in framing and enforcing competition policies, hence, a suitable policy to reduce risk is the immediate need of the hour.
Biochemical biomarkers alterations in Coronavirus Disease 2019 (COVID-19)
Authors: Ciaccio Marcello , Agnello Luisa 
Published: July 2020

Abstract
Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a respiratory disease, which can evolve into multi-organ failure (MOF), leading to death. Several biochemical alterations have been described in COVID-19 patients. To date, many biomarkers reflecting the main pathophysiological characteristics of the disease have been identified and associated with the risk of developing severe disease. Lymphopenia represents the hallmark of the disease, and it can be detected since the early stage of infection. Increased levels of several inflammatory biomarkers, including c-reactive protein, have been found in COVID-19 patients and associated with an increased risk of severe disease, which is characterised by the so-called “cytokine storm”. Also, the increase of cardiac and liver dysfunction biomarkers has been associated with poor outcome. In this review, we provide an overview of the main biochemical characteristics of COVID-19 and the associated biomarkers alterations.
Assessment of Mechanical and Tribological Properties of Diamond-Like Carbon Coatings on the Ti13Nb13Zr Alloy

Published: July 2020

Abstract
The paper presents the results of tests on the geometric structure of the surface, hardness and tribological tests of coatings produced by the method of physical vapor deposition (PVD) on the Ti13Nb13Zr alloy. Hardness was determined using MCT3 from Anton Paar, by instrumental indentation. A diamond indenter with Berkovich geometry was used for the measurement.Model tribological tests were carried out in reciprocating motion under conditions of technically dry friction, friction with lubrication of synovial fluid and Ringer’s solution. The counter-sample in the tested friction nodes was a ball of Al2O3 with a diameter of 6 mm. Nanometer hardness measurements showed that as a result of the diamond-like carbon coating (DLC), the hardness increased by an 7-fold. The lowest friction coefficients among all tested friction nodes were obtained for the material combination Ti13Nb13Zr a-C:H - Al2O3 regardless of the conditions of testing. In the case of technically dry friction, the coefficient of friction decreased by 80%, synovial fluid by 70%, and in the case of Ringer’s solution by 88% compared to the results obtained for Ti13Nb13Zr.
Not So Vain After All: Hannah Arendt’s Reception of Ecclesiastes
Authors: Lasater Phillip Michael 
Published: July 2020

AbstractAlthough Hannah Arendt only explicitly references the book of Ecclesiastes in order to contrast its views with her own, she and Qoheleth parallel each other on substantive issues. After showing how an influential translation of a key motif from Ecclesiastes led Arendt to misapprehend Qoheleth, this study unpacks their intellectual common ground on matters of affirming worldly life; the nature of action; and critical views of the human heart. Yet this third area which addresses human nature also highlights a divergence between them on how thinking relates to the problem of evil.
Designing Efficient Dyadic Operations for Cryptographic Applications
Authors: Banegas Gustavo , Barreto Paulo S. L. M. , Persichetti Edoardo , Santini Paolo 
Published: July 2020

AbstractCryptographic primitives from coding theory are some of the most promising candidates for NIST’s Post-Quantum Cryptography Standardization process. In this paper, we introduce a variety of techniques to improve operations on dyadic matrices, a particular type of symmetric matrices that appear in the automorphism group of certain linear codes. Besides the independent interest, these techniques find an immediate application in practice. In fact, one of the candidates for the Key Exchange functionality, called DAGS, makes use of quasi-dyadic matrices to provide compact keys for the scheme.

Published: July 2020

Abstract
2019 novel coronavirus disease (COVID-19, previously known as novel coronavirus pneumonia) was first discovered in December 2019 and spread widely in China and all over the world in 2020. The initial symptoms of most patients include fever, cough, and fatigue. Dyspnea may occur with the progress of the disease, and acute respiratory distress syndrome may occur in severe cases. The CT manifestations of this disease are mainly ground-glass opacity (GGO) in the lung, which may be accompanied by patchy consolidation, and fibrous changes may appear in the lung at the later stage of the disease. Combined with typical clinical and imaging findings and positive nucleic acid test results, the disease can be diagnosed. We report the first case of novel coronavirus disease (COVID-19) in Heilongjiang Province, China. The patient was seriously ill, who felt that he suffered from fever, fatigue, cough, and expectoration and sought medical treatment, with a history of contact with Wuhan. The leukocyte count was normal, and the lymphocyte count was decreased. CT imaging showed large GGO and partial patchy consolidation in both lungs. The patient recovered and was discharged after 26 days of treatment. This study is helpful for early diagnosis and timely clinical management by mastering the typical imaging of novel coronavirus disease (COVID-19).
Moral psychology of sex robots: An experimental study − how pathogen disgust is associated with interhuman sex but not interandroid sex

AbstractThe idea of sex with robots seems to fascinate the general public, raising both enthusiasm and revulsion. We ran two experimental studies (Ns = 172 and 260) where we compared people’s reactions to variants of stories about a person visiting a bordello. Our results show that paying for the services of a sex robot is condemned less harshly than paying for the services of a human sex worker, especially if the payer is married. We have for the first time experimentally confirmed that people are somewhat unsure about whether using a sex robot while in a committed monogamous relationship should be considered as infidelity. We also shed light on the psychological factors influencing attitudes toward sex robots, including disgust sensitivity and interest in science fiction. Our results indicate that sex with a robot is indeed genuinely considered as sex, and a sex robot is genuinely seen as a robot; thus, we show that standard research methods on sexuality and robotics are also applicable in research on sex robotics.

El objetivo del estudio fue determinar el valor nutritivo, la fermentación ruminal y la producción de metano in vitro del follaje de especies arbóreas y arbustivas con potencial forrajero como estrategias de alimentación en época de secas y mitigación de las emisiones de metano. El líquido ruminal fue extraído por medio de una sonda esofágica. Se utilizó un diseño en bloques repetidos en el tiempo. El contenido de proteína cruda (PC) y fibra detergente neutro y acida fluctuaron de 6.14% a 21.78%, 44.34% a 77.43% y 16.12% a 49.53% de materia seca (MS). No se encontró diferencia en el volumen máximo de gas (p > 0.05). La degradabilidad fue diferente, observando la mejor en Tithonia diversifolia (760.40 g/kg de MS), Morus alba (800.66 g/kg de MS) y Hibiscus rosa-sinensis (800.16 g/kg de MS), mientras que la más baja fue Megatryrsus maximus (390.40 g/kg de MS y 287.40 g/kg de materia orgánica (MO)) (p < 0.05). No se observó diferencia en la producción de metano (CH4) (p > 0.05). Se concluye que L. leucocephala, P. piscipula, B. alicastrum y G. ulmifolia, T. diversifolia y M. alba tienen un alto potencial para ser incluidos en la dieta de rumiantes como fuentes de proteína en época de secas y estrategias para mitigar las emisiones de metano.

ABSTRACT
The postpartum period is the stage after childbirth and is associated with many physical and psychological changes. Exercise has been shown to be beneficial for both the physical and psychological health of a new mother. Previous literature has examined the effect of both aerobic and resistance training in this period; however, there have been no clear guidelines and recommendations provided. Therefore, the purpose of this article is to review the benefits of exercise in the postpartum period, and to provide guidelines and a sample 6-week aerobic and resistance training program after exercise initiation after delivery and medical clearance. A video abstract describing this article can be found in Supplemental Digital Content 1 (see video, http://links.lww.com/SCJ/A295).
