Published: April 2020

Preeclampsia (PE), a common obstetrical disorder, is characterized by impaired migration and invasion abilities of trophoblastic cells. MicroRNA-183-5p (miR-183) was reported to regulate cell migration and invasion in various types of human cancers; however, its role in the pathogenesis of PE remains elusive. Herein, we investigated the role of miR-183 in HTR-8/SVneo trophoblast cells invasion and migration and explored the underlying mechanism. Our results showed that miR-183 was significantly up-regulated in placental tissues from pregnant women compared with that in normal pregnant women. Overexpression of miR-183 inhibited proliferation, migration and invasion, as well as induced apoptosis in HTR-8/SVneo cells. Otherwise, down-regulation of miR-183 achieved the opposite effects. Bioinformatics prediction and luciferase reporter assay confirmed that matrix metalloproteinase-9 (MMP-9) is a target of miR-183. In addition, MMP-9 expression was significantly down-regulated, and inversely correlated with the miR-183 level in placental tissues from pregnant women with severe PE. Down-regulation of MMP-9 suppressed the trophoblast cell invasion and migration, whereas overexpression of MMP-9 promoted cell invasion and migration in HTR-8/SVneo cells. More importantly, up-regulation of MMP-9 reversed the inhibitory effects of miR-183 on cell invasion and migration in trophoblast cells. Collectively, our findings suggested that miR-183 may play critical roles in the pathogenesis of PE and serve as a potential biomarker for severe PE.
Effects of nebivolol versus other antihypertensive drugs on the endothelial dysfunction in patients with essential hypertension
Authors: Li Bingwei , Zhang Qiuju , Zhang Honggang , Wang Chunxiao , Xiu Ruijuan
Published: April 2020

We aim to determine whether nebivolol has a better effect on endothelial dysfunction compared with other β-blockers or other classes of antihypertensive drugs. Searches of the PubMed, Embase etc. were performed to analyze all the randomized controlled trials using nebivolol to treat essential hypertension. The primary end points included a measurement of peripheral endothelial function by brachial flow mediated vasodilatation (FMD) or forearm blood flow (FBF). A random-effect model was used to perform the meta-analysis when the studies showed significant heterogeneity, otherwise a descriptive analysis was conducted. Ten studies (689 patients) were included in qualitative analysis, four of which were included in quantitative synthesis. Meta-analysis showed that the changed FMD value before and after treatment with nebivolol was not statistically different from those treated with other β-blockers [mean difference = 1.12, 95% confidence interval (CI): −0.56, 2.81, P=0.19]. Descriptive analysis indicated that nebivolol did not have a better endothelium-protective effect than other classes of antihypertensive drugs including olmesartan and perindopril. Nebivolol is not a unique endothelial function-protective agent distinguished from other β-blockers or other classes of antihypertensive drugs. Reversal of endothelial dysfunction is a key point in the prevention and therapy of essential hypertension.
Low‐complexity architecture for AR(1) inference

In this Letter, the authors propose a low‐complexity estimator for the correlation coefficient based on the signed process. The introduced approximation is suitable for implementation in low‐power hardware architectures. Monte Carlo simulations reveal that the proposed estimator performs comparably to the competing methods in the literature with maximum error in order of . However, the hardware implementation of the introduced method presents considerable advantages in several relevant metrics, offering more than 95% reduction in dynamic power and doubling the maximum operating frequency when compared to the reference method.
Parallel architecture to accelerate superparamagnetic clustering algorithm
Authors: Wang Pan Ke , Chen Chang Hao , Pun Sio Hang , Zhang Baijun , Mak Peng Un , Vai Mang I. , Lei Tim C.
Published: April 2020

Superparamagnetic clustering (SPC) is an unsupervised classification technique in which clusters are self‐organised based on data density and mutual interaction energy. Traditional SPC algorithm uses the Swendsen–Wang Monte Carlo approximation technique to significantly reduce the search space for reasonable clustering. However, Swendsen–Wang approximation is a Markov process which limits the conventional superparamagnetic technique to process data clustering in a sequential manner. Here the authors propose a parallel approach to replace the conventional appropriation to allow the algorithm to perform clustering in parallel. One synthetic and one open‐source dataset were used to validate the accuracy of this parallel approach in which comparable clustering results were obtained as compared to the conventional implementation. The parallel method has an increase of clustering speed at least 8.7 times over the conventional approach, and the larger the sample size, the more increase in speed was observed. This can be explained by the higher degree of parallelism utilised for the increased data points. In addition, a hardware architecture was proposed to implement the parallel superparamagnetic algorithm using digital electronic technologies suitable for rapid or real‐time neural spike sorting.
PI‐based and anti‐windup transmission power control for WirelessHART field devices
Authors: da Silva Róger W.P. , Eckhard Diego , Müller Ivan
Published: April 2020

In the last couple of decades, the industry saw an increase in the number of wireless sensor networks (WSNs) in replacement of the old cabled technology due to lower deployment and maintenance costs. To keep this momentum, those industrial WSN (IWSN) must assure robustness, scalability, low power, and low maintenance, and the network protocol stack is an important piece of this puzzle. One great dilemma faced by IWSN protocols is how to sustain reliable radio links while avoiding draining too much energy from the battery. In this context, Wireless HART (WH) and ISA SP100.11a, for example require the hardware of the nodes to provide multiple power levels for transmission. Unfortunately, those protocols do not provide a standard procedure to choose between those levels. A simple but inefficient solution often employed simply chooses the highest level available. Seeking a better solution, this proposal presents a transmission power control (TPC) methodology that allows energy saving while sustaining the quality of the communication link employing a simple proportional–integral (PI) controller plus anti‐windup. The proposed approach does not rely on special TPC‐related packets, which is advantageous in comparison with other approaches from the literature by allowing this work to be fully compliant with existing IWSN protocols.

Published: April 2020

Context.Hydrogen-dominated atmospheres of hot exoplanets expand and escape hydrodynamically due to the intense heating by the X-ray and extreme ultraviolet (XUV) irradiation of their host stars. Excess absorption of neutral hydrogen has been observed in the Lyαline during transits of several close-in gaseous exoplanets, indicating such extended atmospheres.

Aims.For the hot Jupiter HD 189733b, this absorption shows temporal variability. We aim to study if variations in stellar XUV emission and/or variable stellar wind conditions may explain this effect.

Methods.We applied a 1D hydrodynamic planetary upper atmosphere model and a 3D magnetohydrodynamic stellar wind flow model to study the effect of variations of the stellar XUV irradiation and wind conditions at the planet’s orbit on the neutral hydrogen distribution. This includes the production of energetic neutral atoms (ENAs) and the related Lyαtransit signature.

Results.We obtain comparable, albeit slightly higher Lyαabsorption than that observed in 2011 with a stellar XUV flux of 1.8 × 104erg cm−2s−1, rather typical activity conditions for this star. Flares with parameters similar to that observed eight hours before the transit are unlikely to have caused a significant modulation of the transit signature. We find that the resulting Lyαabsorption is dominated by atmospheric broadening, whereas the contribution of ENAs is negligible, as they are formed inside the bow shock from decelerated wind ions that are heated to high temperatures. Thus, within our modeling framework and assumptions, we find an insignificant dependence of the absorption on the stellar wind parameters.

Conclusions.Since the transit absorption can be modeled with typical stellar XUV and wind conditions, it is possible that the nondetection of the absorption in 2010 was affected by less typical stellar activity conditions, such as a very different magnitude and/or shape of the star’s spectral XUV emission, or temporal and/or spatial variations in Lyαaffecting the determination of the transit absorption.

The Radio and Plasma Waves (RPW) instrument on the ESA Solar Orbiter mission is described in this paper. This instrument is designed to measure in-situ magnetic and electric fields and waves from the continuous to a few hundreds of kHz. RPW will also observe solar radio emissions up to 16 MHz. The RPW instrument is of primary importance to the Solar Orbiter mission and science requirements since it is essential to answer three of the four mission overarching science objectives. In addition RPW will exchange on-board data with the other in-situ instruments in order to process algorithms for interplanetary shocks and type III langmuir waves detections.
Le secret médical
Authors: Pujalte Christian-Renaud
Published: April 2020

En droit le secret médical relève de cette catégorie de thèmes qui sont d’une actualité permanente. À cela une raison essentielle, le secret médical fait partie intégrante d’un véritable phénomène, récent car il ne remonte qu’à une trentaine d’années, mais en expansion croissante que l’on qualifie de « Judiciarisation de la Société ». Celle-ci se caractérise par l’immixtion en force du droit dans des domaines qui lui étaient le plus souvent étranger, ainsi en est-il du monde des affaires, de la police, des armées… et, en ce qui nous concerne, de la médecine. Certes il n’était pas totalement absent, ceci serait impossible dans un État de droit, mais il était limité à quelques grands principes, et à des lois-cadres que le juge appliquait sans essayer de faire lui-même œuvre normative.

Il en va tout différemment à présent où il est demandé au magistrat, bien sûr de juger, mais ce avec une approche résolument nouvelle.

Il doit en effet tenir compte de l’évolution de la société et des grands courants qui la traversent. Le juge devient de plus en plus le régulateur de bien des activités, il ne se borne plus à faire une simple application des textes il innove, de façon prétorienne, pour essayer de traduire en droit les aspirations du plus grand nombre des administrés.
La brève communication en entretien n’est pas qu’une écoute brève !
Authors: Troussier Thierry
Published: April 2020

Durant la deuxième moitié du xxe siècle, l’entretien (counseling) centré sur la personne, associant une écoute dite active respectant le patient/usagers a fait ses preuves dans la relation aidant /aidé. Ces techniques ont pu s’adapter en fonction des cultures, des contextes et des différents topiques. Elles ont été utilisées dans de très larges spectres (conseil conjugal, accompagnement à la mort, révélation de maladies graves…).

Le début du xxie siècle a permis de décrire de nouveaux outils permettant des entretiens plus rapides et tout aussi efficaces dans certains domaines tels que les entretiens pour améliorer l’adhésion aux thérapeutiques ou pour trouver ses propres ressources pour faire face à ses pratiques à risques. Ces dernières années de nouveaux outils sont utilisés pour améliorer l’efficacité sur le changement des comportements à risque et avoir une approche plus globale de l’individu et de son environnement dans la vraie vie. Ces outils sont principalement utilisés dans le cadre du model IMB ou « Intervention, Motivation and Behavior » (comportement). La brève communication est un processus de communication qui peut être utilisé par tous les professionnels de santé, formé à des techniques d’écoute brève, elle se réalise en moins d’une demi-heure, souvent en quelques minutes après avoir entendu la demande du patient, et avoir intégré ses déterminants environnementaux.

Menyanthes trifoliata L. – der Fieberklee
Authors: Latté Klaus Peter
Published: April 2020

Die Blatt- und Rhizomdroge des in Moor- und Sumpfgebieten vorkommenden Fieberklees, Menyanthes trifoliata L. (Menyanthaceae), wird seit Langem volksmedizinisch bei Appetitlosigkeit und Verdauungsbeschwerden eingesetzt; maßgeblich an dieser Wirkung sind die enthaltenen Bitterstoffe vom Secoiridoid-Typ beteiligt, die auch in anderen Bitterstoffdrogen vorkommen. Neben Bitterstoffen sind Polyphenole und Triterpene wichtige Inhaltsstoffe beider Drogen. In Untersuchungen wurden für Blattextrakte antioxidative, antimikrobielle und immunmodulatorische Wirkungen sowie für Rhizomextrakte antiinflammatorische, antioxidative und antimikrobielle Aktivitäten und zytotoxische Wirkungen gegen Krebszelllinien beschrieben. Genaue toxikologische Daten liegen für beide Drogen nicht vor. Klinische Studien sind nicht verfügbar, so dass eine Anwendung der Blatt- und Rhizomdrogen bzw. von Extrakten – abgesehen von der Verwendung bei Appetitlosigkeit und Verdauungsbeschwerden im Sinne eines „traditional use“ – nicht empfohlen werden kann.

A Surgical Technique to Repair Perineal Body Disruption Secondary to Sexual Assault
Authors: Brisighelli Giulia , Levitt Marc A. , Wood Richard J. , Westgarth-Taylor Christopher J.
Published: April 2020

Perineal trauma is uncommon in the pediatric population and it is estimated that 5 to 21% is secondary to sexual abuse. We aim to present a proposed surgical technique to repair perineal injuries secondary to sexual assault in female children. The technique is based on the posterior sagittal anorectoplasty (PSARP) for repairing anorectal malformations and, between 2017 and 2019, it was used to treat three girls (2 months, 2 years, and 8 years of age) with fourth-degree perineal injuries secondary to sexual assault. One of them underwent laparotomy and Hartmann's colostomy for an acute abdomen. Two underwent wound debridement and suturing and only had a stoma fashioned at 5 days and 6 weeks posttrauma, respectively. The perineal repair was performed 2, 6, and 7 weeks postinjury and done as follows: with the child prone in jack-knife position, stay-sutures are placed on the common wall between the rectum and the vagina. Using a needle tip diathermy, a transverse incision is performed below the sutures lifting the anterior rectal wall up. Stay sutures are then positioned on the posterior wall of the vaginal mucosa. The incision between the walls is deepened until the rectum and the vagina are completely separated. The deep and superficial perineal body is then reconstructed using absorbable sutures and an anterior anoplasty and an introitoplasty are performed. The stoma in each was closed 6 weeks postreconstruction. At follow-up, now 1 year or more postrepair, all patients have an excellent cosmetic outcome and are fully continent for stools.
Changes in Electrical Activity of the Masseter Muscle and Masticatory Force after the Use of the Masseter Nerve as Donor in Facial Reanimation Surgery

Introduction The masseter nerve has been used as a donor nerve for facial reanimation procedures due to the multiple advantages it offers; it has been generally considered that sacrifice of the masseter nerve does not alter the masticatory apparatus; however, there are no objective studies to support this claim.

Objective To evaluate the impact that the use of the masseter nerve in dynamic facial reconstruction has on the electrical activity of the masseter muscle and on bite force.

Materials and Methods An observational and prospective longitudinal study was performed measuring bite force and electrical activity of the masseter muscles before and 3 months after dynamic facial reconstructive surgery using the masseter nerve. An occlusal analyzer and surface electromyography were employed for measurements.

Results The study included 15 patients with unilateral facial paralysis, with a mean age of 24.06 ± 23.43. Seven patients were subjected to a masseter–buccal branch nerve transfer, whereas in eight patients, the masseter nerve was used as a donor nerve for gracilis free functional muscle transfer. Electrical activity of the masseter muscle was significantly reduced after surgery in both occlusal positions: from 140.86 ± 65.94 to 109.68 ± 68.04 (p = 0.01) in maximum intercuspation and from 123.68 ± 75.64 to 82.64 ± 66.56 (p = 0.01) in the rest position. However, bite force did not show any reduction, changing from 22.07 ± 15.66 to 15.56 ± 7.91 (p = 0.1) after the procedure.

Conclusion Masseter nerve transfer causes a reduction in electromyographic signals of the masseter muscle; however, bite force is preserved and comparable to preoperative status.
Summary of Oncologic and Functional Outcomes
Authors: Hompes Roel , Penna Marta
Published: April 2020

Large cohort and collaborative studies to date have shown that the short-term oncological outcomes appear to be at least as good as traditional laparoscopic surgery. These results need confirmation in randomized controlled trials, which are currently underway (GRECCAR 11 and COLOR III). The functional data on transanal total mesorectal excision is still very scarce and more mature data on quality of life and function outcomes are eagerly awaited.
Future Directions

Published: April 2020

Transanal total mesorectal excision (taTME) is a novel technique that has evolved over the years to address the challenges of low rectal cancer surgery by applying the principles and benefits of laparoscopic surgery to more historic transanal techniques. It has been popularized through its use in rectal cancer, but the transanal approach is slowly being expanded to tackle different clinical scenarios including benign conditions such as inflammatory bowel disease and endometriosis. For all of these new indications, it is the desire to access and begin the dissection in native tissue beyond the pathology which makes this approach applicable to other diseases where anatomy can be challenging. Training pathways to safely introduce taTME in a standardized manner are being developed and implemented in a bid to ensure adequate training to all the surgeons using this technique and thus minimize complications and patient morbidity. The future directions of this promising technique include the use of image and optical technological enhancement to aid navigation, the use of pneumorectum stabilization, and perhaps the use of fluorescence as a safety improvement. Developments have come also from the field of robotics. After a demonstration of feasibility in cadaver models, a growing experience has been gathered in the robotic approach to taTME, covered in the last part of this chapter.
A Case of Right Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo with to-and-fro Canal Switch to Right Horizontal Semicircular Canal
Authors: Vats Ajay Kumar
Published: April 2020

Background Canal switch in BPPV is a phenomenon occurring after therapeutic canalith repositioning maneuvers (CRM), when there is a reflux of the repositioned otoconial debris from utricle to semicircular canal other than the one originally affected. It may be of immediate-type occurring within minutes after CRM or a delayed-type occurring after 2-3 days.

Aim The study is a case report.

Case Report A 59-year-old female presented with history of severe rotational vertigo as she got up from the bed in the early morning at 5.00 a.m.. Dix-Hallpike test (DHT) on the right elicited an upbeating positional nystagmus (PN). Treatment with multiple consecutive modified right Epley maneuvers (r-MEM) in one session was undertaken. During these maneuvers she continued to have an upbeating PN during the 45-degrees right cervical rotation with the neck in 20-degrees of extension (which is equivalent to right Dix-Hallpike positioning) of the first three sequential r-MEM’s. With the neck maintained in 20-degrees of extension, during fourth consecutive r-MEM, the 45-degrees cervical rotation to right elicited apogeotropic horizontal PN. Supine roll test (SRT) was immediately undertaken. Maximal head yaw positioning to right as well as to the left elicited apogeotropic horizontal PN without torsional component lasting more than one minute, indicating reflux of otoconia from the right P-SCC to the short anterior arm of right H-SCC. She was treated with two sequences of Appiani maneuver and SRT one hour later elicited geotropic upbeating PN with vertigo, indicating second canal switch to P-SCC. It was successfully treated with two sequences of right EM fifteen minutes apart, with instructions to stay upright in between and after the maneuvers. At 24 hours, repeat DHT and SRT were negative and patient was asymptomatic.

Conclusion An optimal time delay to perform a verifying positional test after therapeutic session with CRM is crucial to prevent the immediate type of reflux of relocated otoconia from the utricle into a different semicircular canal. In centers, where more than a single EM is performed in a single session of treatment, a delay of 10 to 15 minutes appears to be appropriate between successive maneuvers. A certain period of restraint in the vertical position after CRM may prevent immediate reflux, but this needs to be confirmed by the randomized control trials.
Nonpharmacological Treatment of Atrial Fibrillation: What Is the Role of Device Therapy?
Authors: Riedlbauchová Lucie , Durdil Václav , Honěk Jakub , Veselka Josef
Published: April 2020

Atrial fibrillation is the most common arrhythmia in the adult population, and its incidence and prevalence are still rising. Cardiac devices are widely used in clinical practice in the management of various rhythm disturbances and heart failure treatment. Many patients who receive a pacemaker, implantable cardioverter-defibrillator, or cardiac resynchronization therapy also experience atrial fibrillation in the course of their life. Therefore, this review aims to describe the role of these devices in the treatment and prevention of atrial fibrillation in the device recipients. In addition, all these implantable devices also serve as permanent ECG (electrocardiogram) monitors, thus providing important information about the presence and characteristics of atrial fibrillation that may or may not be detected by the patient but can modify our therapeutical approach with regard to the stroke prevention.

Hexagonal boron nitride incorporation to achieve high performance Li4Ti5O12 electrodes
Authors: Ergen Onur
Published: April 2020

There is an increasing demand for fast charging and high capacity lithium ion batteries. However, conventional Li-ion battery chemistries cannot meet the stringent requirements of these demands due to the poor performance of graphite anodes, especially on safety during fast charging. Finding the right anode material that can replace conventional graphite while providing high capacity is very challenging. Today, lithium titanium oxide (LTO) is considered one of the most attractive anode materials that can provide the desired ultra-fast charging ability (>10C) with high safety. However, it has many serious drawbacks when compared to the existing graphite anodes, including poor intrinsic conductivity, narrow electrochemical window, etc. Extensive research has been done to overcome these problems, especially in developing new LTO composite materials with reduced graphene oxide. However, even these methods have rapid capacity fading at high current densities, >5C, due to increased internal resistance and polarization losses. Here, we demonstrate an effective way to improve LTO composite materials by developing unique nanoengineered three-dimensional frameworks with hexagonal boron nitride (h-BN) addition. Li-ion cells with h-BN incorporation exhibit excellent performance and operational stability, especially at fast and ultra-fast charging rates, >10C.

In 2008 the change to the Brazilian legislation regarding the use of natural caves has caused an increase in the number of studies on environmental impacts involving caves. The legislation requires the classification of such environments according to their importance, and caves that are not classified highly may be irreversibly impacted. Thus, caves in rocks of high economic interest have been intensively sampled, which has resulted in the collection of several specimens of Palpigradi in them. The Iron Quadrangle (in Minas Gerais state) stands out among these areas as one the most important sources of iron ore in Brazil. Several palpigrades from this region are housed in collections: most of them belong to the edaphic species Eukoenenia ferratilis, and a small portion belong to new species that are morphologically quite distinct from E. ferratilis, with longer bodies and more elongated appendages, indicating the presence of troglomorphisms. Therefore, the present study aimed to describe three new troglobitic species of Eukoenenia, which can be distinguished morphometrically and by means of some qualitative characters. These descriptions are important for the preservation of the caves where they occur, since the presence of troglobitic species increases the relevance of the caves, which have been severely threatened by mining activities.
Corrigendum to: Phylogeny, evolution and systematic revision of the mite harvestman family Neogoveidae (Opiliones Cyphophthalmi)
Authors: Benavides Ligia R. , Hormiga Gustavo , Giribet Gonzalo
Published: April 2020

Mite harvestmen of the family Neogoveidae have a tropical trans-Atlantic distribution with representatives in equatorial West Africa and the Neotropics, specifically in the south-east region of the USA and in northern South America, being conspicuously absent from Central America. We provide a comprehensive molecular phylogeny of the family including representatives of all genera but the monotypic Tucanogovea Karaman, 2013, and new information on the type species described by Jochen Martens in 1969 that were unavailable for molecular study until now: Brasiliogovea microphaga, Metagovea oviformis and ‘? Gen. enigmaticus'. Additionally, we revisit the somatic and male genitalic morphology of representatives of all genera by means of scanning electron microscopy and confocal laser scanning microscopy, and describe the new genera Leggogovia Benavides & Giribet, gen. nov., Microgovia Benavides, Hormiga & Giribet, gen. nov., Waiwaigovia Benavides, Hormiga & Giribet, gen. nov. and 13 new species: Brasiliogovea aphantostylus Benavides, Hormiga & Giribet, sp. nov., Brasiliogovea microstylus Benavides, Hormiga & Giribet, sp. nov., Brasiliogovea yacambuensis Benavides, Hormiga & Giribet, sp. nov., Metagovea matapi Benavides, Hormiga & Giribet, sp. nov., Metagovea planada Benavides, Hormiga & Giribet, sp. nov., Microgovia chenepau Benavides, Hormiga & Giribet, sp. nov., Neogovea branstetteri Benavides, Hormiga & Giribet, sp. nov., Neogovea enigmatica Martens, sp. nov., Neogovea matawai Benavides, Hormiga & Giribet, sp. nov., Parogovia montealensis Benavides & Giribet, sp. nov., Parogovia prietoi Benavides & Giribet, sp. nov., Parogovia putnami Benavides & Giribet, sp. nov. and Waiwaigovia schultzi Benavides, Hormiga & Giribet, sp. nov. Phylogenetic analyses based on maximum likelihood, parsimony and Bayesian inference support the monophyly of Neogoveidae and a sister group relationship of Neogoveidae + Ogoveidae with Troglosironidae (a clade named Sternophthalmi). Relationships among neogoveid genera are largely congruent between methods as follows: ((Leggogovia gen. nov., Metasiro), (Parogovia, ((Canga, Microgovia gen. nov.), ((Brasiliogovea, Neogovea), (Huitaca, (Waiwaigovia gen. nov., Metagovea)))))). In light of our results, the following taxonomic changes are proposed: Metagovea oviformis Martens, 1969 is transferred to Microgovia, gen. nov.; Parogovia pabsgarnoni Legg, 1990 is transferred to Leggogovia, gen. nov.; ‘? Gen. enigmaticus Martens, 1969' is an invalid name according to the ICZN; the corresponding taxon is redescribed and formally named as Neogovea enigmatica Martens, sp. nov.
Translation in the COVID-19 health emergency in Wuhan
Authors: Wang Peng
Published: April 2020

Intercultural crisis communication in an interconnected and globalized world emphasizes the need for translation
to be put in place as foreign nationals with cultural and linguistic barriers might rely on it to prepare for a possible crisis or
make informed decisions when already affected by a crisis. However, translation is an underdeveloped tool in crisis management,
particularly in China. Considering it a special branch of public service translation, the author investigates crisis translation
by using a case study of the disruptive outbreak of novel coronavirus disease in Wuhan. Based upon the author’s first-hand
experience as a crisis manager at the Office of Foreigner Affairs in the Municipal Government of Wuhan, this article describes how
government translators with the help of external volunteer translators made language services available and accessible to affected
foreign nationals in the response phase from 8 January 2020 to 7 April 2020. It analyses these translation-mediated activities
from a crisis manager’s perspective. Despite the preliminary nature of the findings, which still call for further validation, it
is hoped that insights from this article will be of interest to those who are engaged with crisis translation services and to
those who research crisis translation.
GRAF2, WDR44, and MICAL1 mediate Rab8/10/11–dependent export of E-cadherin, MMP14, and CFTR ΔF508

Published: April 2020

In addition to the classical pathway of secretion, some transmembrane proteins reach the plasma membrane through alternative routes. Several proteins transit through endosomes and are exported in a Rab8-, Rab10-, and/or Rab11-dependent manner. GRAFs are membrane-binding proteins associated with tubules and vesicles. We found extensive colocalization of GRAF1b/2 with Rab8a/b and partial with Rab10. We identified MICAL1 and WDR44 as direct GRAF-binding partners. MICAL1 links GRAF1b/2 to Rab8a/b and Rab10, and WDR44 binds Rab11. Endogenous WDR44 labels a subset of tubular endosomes, which are closely aligned with the ER via binding to VAPA/B. With its BAR domain, GRAF2 can tubulate membranes, and in its absence WDR44 tubules are not observed. We show that GRAF2 and WDR44 are essential for the export of neosynthesized E-cadherin, MMP14, and CFTR ΔF508, three proteins whose exocytosis is sensitive to ER stress. Overexpression of dominant negative mutants of GRAF1/2, WDR44, and MICAL1 also interferes with it, facilitating future studies of Rab8/10/11–dependent exocytic pathways of central importance in biology.

Recent advances in mechanical strain engineering of low-dimensional semiconductors and their applications in high-performance quantum emitters
Authors: Tao Lue , Ou Weiwen , Li Yang , Liao Han , Zhang Jiaxiang , Gan Fuwan , Ou Xin
Published: April 2020

In the past decades, low-dimensional semiconductors received intensive research interest. By introducing intentionally size-confined nanostructures or crystal imperfections, low-dimensional semiconductors have been broadly exploited as zero-dimensional quantum dots (QDs) for high-performance quantum emitters. The QD-based nonclassical light sources allow not only the deterministic generation of single photons but also entangled-photon pairs. However, the randomness in strain, shape and composition in semiconductors results in unpredictable transition energies for different QDs. This complication impedes the generation of single and entangled photons with well-defined energies, which fundamentally limits the success probability of scalable quantum information technologies. Strain engineering, a unique and powerful method to reshape the electronic states of semiconductors, has advanced the development of all-solid-state low-dimensional semiconductor based single and entangled-photon sources. In this review, the recent progress of employing mechanical strain field to control the electronic states and optical properties of low-dimensional semiconductors is reviewed. A comprehensive summary of diverse strain engineered devices for engineering the exciton binding energy, the coherent coupling of electronic states, the optical properties of low-dimensional semiconductors including single and entangled photons are provided. In addition, prospects and challenges of deploying the strain-engineering technique for future scalable quantum networks and photonic quantum circuits are discussed.
Optimal synthesis of the Fredkin gate in a multilevel system
Authors: Liu Wen-Qiang , Wei Hai-Rui
Published: April 2020

The optimal cost of a three-qubit Fredkin gate is 5 two-qubit entangling gates, and the overhead climbs to 8 when restricted to controlled-not (CNOT) gates. By harnessing higher-dimensional Hilbert spaces, we reduce the cost of a three-qubit Fredkin gate from 8 CNOTs to 5 nearest-neighbor CNOTs. We also present a construction of an n-control-qubit Fredkin gate with 2n + 3 CNOTs and 2n single-qudit operations. Finally, we design deterministic and non-deterministic three-qubit Fredkin gates in photonic architectures. The cost of a non-deterministic three-qubit Fredkin gate is further reduced to 4 nearest-neighbor CNOTs, and the success of such a gate is heralded by a single-photon detector. Our insights bridge the gap between the theoretical lower bound and the current best result for the n-qubit quantum computation.
Non-equipotential effect observed on the surface of Ti/Si under uniform illumination
Authors: Mei Chunlian , Liu Shuai , Dong Anhua , Huang Xu , Yu Chongqi , Wang Hui
Published: April 2020

In this letter, a non-equipotential surface photovoltaic effect is reported in nano metal–semiconductor structures. When the surface of the Ti/Si is uniformly illuminated by a beam of light, a controllable surface photovoltaic effect is observed on the metal side. The center of the surface presents a remarkably higher metallic potential than the surrounding region. The surface photovoltage is detected to be as high as 53 mV. Besides, it depends sensitively on the thickness and size of the metal films, demonstrating it is a unique feature of nano metal films. We ascribe this phenomenon to the boundary effect of photon-generated carriers in the ultrathin metal thickness. The theoretical calculations based on equivalent electron diffusion model are in great agreement with the experimental results. The results may promise some novel applications based on the nanoscale metal–semiconductor systems.
Sea quark contributions to nucleon electromagnetic form factors with the nonlocal chiral effective Lagrangian *
Authors: Yang Ming-Yang , Wang Ping
Published: April 2020

The sea quark contributions to the nucleon electromagnetic form factors of the up, down and strange quarks are studied with the nonlocal chiral effective Lagrangian. Both octet and decuplet intermediate states are included in the one loop calculations. Compared with the strange quark form factors, although their signs are the same, the absolute value of the light quark form factors are much larger. For both the electric and magnetic form factors, the contribution of the d quark is larger than of the u quark. The current lattice simulations of the light sea quark form factors are in between our results for the u and dquarks.
The first excited single-proton resonance in 15F by complex-scaled Green's function method *
Authors: Shi Xin-Xing , Liu Quan , Ni Dong-Dong , Guo Jian-You , Ren Zhong-Zhou
Published: April 2020

The complex-scaled Green's function (CGF) method is employed to explore the single-proton resonance in 15F. Special attention is paid to the first excited resonant state 5/2+, which has been widely studied in both theory and experiments. However, past studies generally overestimated the width of the 5/2+ state. The predicted energy and width of the first excited resonant state 5/2+ by the CGF method are both in good agreement with the experimental value and close to Fortune's new estimation. Furthermore, the influence of the potential parameters and quadruple deformation effects on the resonant states are investigated in detail, which is helpful to the study of the shell structure evolution.
Single-particle space-momentum angle distribution effect on two-pion HBT correlation in high-energy heavy-ion collisions
Authors: Yang Hang , Feng Qichun , Ren Yanyv , Zhang Jingbo , Huo Lei
Published: April 2020

We analyze the transverse momentum dependence of HBT radii in relativistic heavy-ion collisions using several source models. Results indicate that the single-particle space-momentum angle distribution plays an important role in the transverse momentum dependence of HBT radii. In a cylinder source, we use several formulas to describe the transverse momentum dependence of HBT radii and the single-particle space-momentum angle distribution. We also make a numerical connection between them in the transverse plane.

Quasinormal modes of charged black holes in Einstein-Maxwell-Weyl gravity *
Authors: Zou De-Cheng , Wu Chao , Zhang Ming , Yue Ruihong
Published: April 2020

We study quasinormal modes (QNMs) of charged black holes in the Einstein-Maxwell-Weyl (EMW) gravity by adopting the test scalar field perturbation. We find that the imaginary part of QNM frequencies is consistently negative for different angular parameters l, indicating that these modes always decay and are therefore stable. We do not observe a linear relationship between the QNM frequency ω and parameter p for these black holes, as their charge Q causes a nonlinear effect. We evaluate the massive scalar field perturbation in charged black holes and find that random long lived modes (i.e., quasiresonances) could exist in this spectrum.
