AbstractIn the aftermath of the corona pandemic, long-COVID or post-acute COVID-19
syndrome still represents a great challenge, and this topic will continue to
represent a significant health problem in the coming years. At present, the
impact of long-COVID on our health system cannot be fully assessed but according
to current studies, up to 40% of people who have been infected with
SARS-CoV-2 suffer from clinically relevant symptoms of long-COVID syndrome
several weeks to months after the acute phase. The main symptoms are chronic
fatigue, dyspnea, and various cognitive symptoms. Initial studies have shown
that people with overweight and diabetes mellitus have a higher risk of
developing long-COVID associated symptoms. Furthermore, repeated treatment of
acute COVID-19 and long-COVID with steroids can contribute to long-term
metabolic and endocrine disorders. Therefore, a structured program with
rehabilitation and physical activity as well as optimal dietary management is of
utmost importance, especially for patients with metabolic diseases
and/or long-COVID. Furthermore, the removal of autoantibodies and
specific therapeutic apheresis procedures could lead to a significant
improvement in the symptoms of long-COVID in individual patients.

AbstractWhen the corona pandemic commenced more than two years ago, it was quickly
recognized that people with metabolic diseases show an augmented risk of severe
COVID-19 and an increased mortality compared to people without these
comorbidities. Furthermore, an infection with SARS-CoV-2 has been shown to lead
to an aggravation of metabolic diseases and in single cases to new-onset
metabolic disorders. In addition to the increased risk for people with diabetes
in the acute phase of COVID-19, this patient group also seems to be more often
affected by long-COVID and to experience more long-term consequences than people
without diabetes. The mechanisms behind these discrepancies between people with
and without diabetes in relation to COVID-19 are not completely understood yet
and will require further research and follow-up studies during the following
years. In the current review, we discuss why patients with diabetes have this
higher risk of developing severe COVID-19 symptoms not only in the acute phase
of the disease but also in relation to long-COVID, vaccine breakthrough
infections and re-infections. Furthermore, we discuss the effects of lockdown on
glycemic control.

Published: June 2022

AbstractA metal and additive-free stereospecific direct N-H and N-Me aziridination of inactivated olefins is disclosed using N-Boc-O-tosyl­hydroxylamine (TsONHBoc) as an aminating agent in hexafluoroisopropanol (HFIP). The use of TsONHBoc, which generates the free aminating agent in situ under the reaction conditions, has several inherent advantages over other similar agents, such as low cost, easy access, and stability (non-explosiveness) during storage over a longer time.
Adult Admissions to a Canadian PICU during the COVID-19 Pandemic
Authors: Holt Tanya , Smith Leanne , Hansen Gregory 
Published: June 2022

AbstractIn response to the burden of coronavirus disease 2019 (COVID-19) and overwhelmed intensive care unit (ICU) resources, some pediatric intensive care units (PICUs) have had to adapt. The purpose of this study was to assess the criticality, scope of diagnosis, and outcomes of an adult cohort admitted to a Canadian PICU. A retrospective chart review was completed on all patients between 17 and 50 years of age admitted to the PICU between June 2020 and December 2021. Admission data included body mass index (BMI), admission sequential organ failure assessment score (SOFA), COVID-19 status, diagnosis, and comorbidities. The duration of ventilatory support, PICU and hospital admission, and mortality and discharge disposition were assessed. Discrete variables were reported as percentages and continuous data as means with standard deviations or medians with interquartile range. Sixty-five adult patients were admitted to the PICU for a total of 437 days, with a mean SOFA score of 6.6 and the overall mortality rate of 4.6%. Six patients were diagnosed with COVID-19 pneumonia, were admitted with a mean SOFA score of 11.8 and a BMI of 38.3 kg/m2, and all were discharged to the ward. During the COVID-19 pandemic, pediatric intensivists in a Canadian PICU managed adult patients up to 50 years of age with high criticality and broad-ranging diagnoses with a low mortality rate. PICUs may be a safe critical care decompression option for adult ICUs during future endemics or pandemics.
Character perspective shift sequences and embodiment markers in signed and spoken discourse
Authors: Parisot Anne-Marie , Saunders Darren 
Published: June 2022

AbstractThe aim of this study is to present a distributional portrait of forms of character-perspective sequences as produced by LSQ (Langue des signes québécoise) signers and Quebec French speakers, in relation to corporal and grammatical marking in a set of recorded discourses. Among the forms we examine are grammatical, corporal and rhythm markers. As for the types of character perspective shift examined, we focus on the nature of the event that is being enacted: speech, thought, action or gesture. The dataset employed in the study consists of short, elicited narratives using video sketches as stimuli. Both Deaf signers and French speakers were asked to describe short scenarios that were displayed without any signing or speech. Half of the stimuli were constructed from a series of factual events containing no emphatic reactions or actions, while the other half included emphatic elements. Twenty-four narratives produced by these two groups were transcribed and coded using ELAN to determine the distribution of character perspective shift sequences (CPS) used in terms of presence (duration) and frequency (occurrences). Further markers were also identified in terms of frequency, which was then analyzed with a factorial ANOVA statistical model. The overall finding of this study is that CPS is used in both language groups, despite their varying results in terms of the distribution of frequency and markers.
Functional adequacy, task-based language teaching and instructed second language acquisition
Authors: Loewen Shawn 
Published: June 2022

Abstract
This commentary synthesizes the five articles in Kuiken and Vedder’s special issue on functional adequacy in
linguistic performance. The commentary considers the different scales that were used to measure functional adequacy, as well as
the relationship between functional adequacy and other measures of linguistic performance such as complexity, accuracy, and
fluency. The commentary also considers how functional adequacy might be usefully incorporated more frequently into studies from a
task-based language teaching or instructed second language acquisition perspective, both as pedagogical instruction and as a means
of measuring linguistic development.
The present and future of functional adequacy
Authors: González-Lloret Marta 
Published: June 2022

AbstractThe concept of Functional Adequacy (FA) proposed by Kuiken and Vedder, and the research conducted by the authors in this special issue is pushing the field of Task- Based Language Teaching (TBLT) and Task-Based Language Assessment (TBLA) towards a more inclusive understanding of what it means to perform a task successfully. In addition, the idea of FA is an important contribution not just for assessment but for research on L2 pragmatic learning through tasks. As demonstrated by the authors in this special issue, the FA rating scale is a reliable and easy-to-use tool. And as I argue, the rating scale can be expanded to assess interactional tasks and tasks mediated by technology, and that has repercussion for practice in the language classroom as well as for research in the fields of TBLT, TBLA, and L2 Pragmatics.
Amorphous silicon nitride deposited by an NH3-free plasma enhanced chemical vapor deposition method for the coatings of the next generation laser interferometer gravitational waves detector

Published: June 2022

Abstract
Cryogenic mechanical loss of the mirror coatings will result in thermal noise and limit the sensitivity of the next generation laser interferometer gravitational wave detectors operated at cryogenics. Amorphous silicon nitride (aSiN) films deposited by NH3 plasma enhanced chemical vapor deposition (NH3-PECVD), a coating method with potential in large area uniform coatings for the next generation detectors, were found previously to have a low cryogenic mechanical loss and without loss peaks that are common in current coatings for room temperature detectors. A positive correlation between N–H bond density and cryogenic mechanical loss in the aSiN films has been observed previously, and the existence of an N–H bond-related asymmetrical two-level system was postulated to account for the cryogenic mechanical loss. In this report, we studied an NH3-free PECVD process to reduce the N–H bond concentration and hence reducing the cryogenic mechanical loss. The N–H bond density of all films deposited by the NH3-free PECVD method was reduced to below the detection limit (<1020 cm−3). The composition of the optimized film is SiN0.33H0.58 which shows the lowest extinction coefficient (1.21 × 10−5 @ 1550 nm), a high refractive index (2.68 @ 1550 nm), and excessively low stress (20.8 MPa), respectively. From 10 K to 120 K, cryogenic mechanical loss of the as-deposited SiN0.33H0.58 varies from 5 × 10−5 to 8 × 10−5 which is two to three times lower than that of the best NH3-PECVD silicon nitride previously obtained. No distinctive cryogenic loss peak was found as well.
On non-Euclidean Newtonian theories and their cosmological backreaction
Authors: Vigneron Quentin 
Published: June 2022

Abstract
Constructing an extension of Newton’s theory which is defined on a non-Euclidean topology (in the sense of Thurston’s decomposition), called a non-Euclidean Newtonian theory, corresponding to the zeroth order of a non-relativistic limit of general relativity is an important step in the study of the backreaction problem in cosmology and might be a powerful tool to study the influence of global topology on structure formation. After giving a precise mathematical definition of such a theory, based on the concept of Galilean manifolds, we propose two such extensions, for spherical or hyperbolic topologies, using a minimal modification of the Newton–Cartan equations. However as for now we do not seek to justify this modification from general relativity. The first proposition features a non-zero cosmological backreaction, but the presence of gravitomagnetism and the impossibility of performing exact N-body calculations make this theory difficult to be interpreted as a Newtonian-like theory. The second proposition features no backreaction, exact N-body calculation is possible and no gravitomagnetism appears. In absence of a justification from general relativity, we argue that this non-Euclidean Newtonian theory should be the one to be considered, and could be used to study the influence of topology on structure formation via N-body simulations. For this purpose we give the mass point gravitational field in

Anisotropic quark stars in f(R) =

1+ϵ
gravity
Authors: Pretel Juan M Z , Duarte Sérgio B 
Published: June 2022

Abstract
Within the metric formalism of f(R) theories of gravity, where R is the Ricci scalar, we study the hydrostatic equilibrium structure of compact stars with the inclusion of anisotropic pressure. In particular, we focus on the f(R) = R
1+ϵ
model and we examine small deviations from general relativity for |ϵ| ≪ 1. A suitable definition of mass function is explicitly formulated from the field equations and the value of the Ricci scalar at the center of each star is chosen such that it satisfies the asymptotic flatness requirement. We find that both the mass and the radius of a compact star are larger with respect to the general relativistic counterpart. Furthermore, we remark that the substantial changes due to anisotropy occur mainly in the high-central-density region.

Abstract
The rapid development of advanced manufacturing technologies in micro-electro-mechanical system (MEMS) fields has promoted the advance in wearable electronics. Among them, wearable biomechanical micro-energy harvesters have attracted much attention in recent years to meet the unique power supply demands of wearable electronics serving as sustainable power sources. In the meanwhile, they also have been successfully demonstrated to be either self-powered sensors or other functional devices for wearable electronic applications. Herein, we overview the state-of-the-art of biomechanical micro-energy harvesters for wearable electronic applications, including the summary of working principles and structural configurations of biomechanical micro-energy harvesters. In detail, three promising technologies for biomechanical micro-energy harvesting are studied, i.e. electromagnetic effect, piezoelectric effect, and electrostatic effect. As for the structural configurations, two essential factors to affect the properties of biomechanical micro-energy harvesters are emphasized, i.e. new materials, and advanced manufacturing technologies. For wearable application scenarios, fiber/fabric-based materials and biodegradable/ecofriendly materials are investigated. For advanced manufacturing technologies, micro/nano fabrication technologies for precise fabrication and large-scale fabrication technologies for mass fabrication are summarized. Moreover, we review the wearable electronic applications of biomechanical micro-energy harvesters for powering, sensing, and actuating, respectively, which reveals the feasibility of constructing the smart wearable microsystems based on the abundant function of biomechanical micro-energy harvesters. Finally, we conclude the review and discussed the future development trends of biomechanical micro-energy harvesters for wearable electronic applications.
Modelling and experimental investigations of composition-dependent heat and mass transfer during Cu–Ni alloy nanoparticle synthesis in a transferred arc helium plasma

Published: June 2022

Abstract
In the synthesis of alloy nanoparticles (NPs) via arc evaporation and fast quenching, the composition of the synthesized NPs differs significantly from that of the precursor. The properties of the NPs formed following evaporation of a copper–nickel anode by a helium arc are investigated using a nucleation model coupled to the thermal and flow fields derived from a magneto-hydrodynamic simulation of the arc, and experimentally. Results are obtained for three different Cu:Ni precursor compositions, 10:90, 50:50 and 90:10 at%. The synthesized particles are spherical with different size distributions and have a higher concentration of Cu than the precursor in all three cases, in contrast to previous observations, but in accordance with the predictions of the model. Emission spectroscopic measurements of copper and nickel lines indicate that the concentration of atomic copper in the plasma region near the anode is much higher than that of the nickel, in accordance with the predictions of the model. The higher vapour pressure of copper compared to nickel, and its higher activity in the alloy precursor (anode), immersed in a self-consistent thermal and flow field maintained by the transferred arc are found to play a critical role. The thermodynamic, radiative and transport properties of the helium plasma contaminated with evaporated precursor are important in determining the thermal and flow fields.
A new type of cyclotron resonance from charge-impurity scattering in the bulk-insulating Bi2Se3 thin films
Authors: Han Xingyue , Salehi Maryam , Oh Seongshik , Wu Liang 
Published: June 2022

Abstract
This work focuses on the low frequency Drude response of bulk-insulating topological insulator (TI) Bi2Se3 films. The frequency and field dependence of the mobility and carrier density are measured simultaneously via time-domain terahertz spectroscopy. These films are grown on buffer layers, capped by Se, and have been exposed in air for months. Under a magnetic field up to 7 Tesla, we observe prominent cyclotron resonances (CRs). We attribute the sharp CR to two different topological surface states from both surfaces of the films. The CR sharpens at high fields due to an electron-impurity scattering. By using magneto-terahertz spectroscopy, we confirm that these films are bulk-insulating, which paves the way to use intrinsic TIs without bulk carriers for applications including topological spintronics and quantum computing.
Ga3Te3I: novel 1D and 2D semiconductor materials with promising electronic and optical properties
Authors: Zhang Fumin , Wang Bing , Yin Huabing 
Published: June 2022

Abstract
Due to their unique properties and potential applications, low-dimensional van der Waals (vdW) materials, including two-dimensional (2D) nanosheets and one-dimensional (1D) atomic chains, have caused widespread interest. Herein, based on first-principles calculations, we introduce a Ga3Te3I material as an example of novel 2D- and 1D-vdW-based materials. The 2D monlayer and 1D nanochain of Ga3Te3I can be isolated from their bulk counterpart by mechanical exfoliation and possess good dynamical and thermal stability. The electronic, transport, and optical properties of 2D monolayer and 1D nanochain were studied comprehensively. Remarkably, the modest band gaps, 1.98 eV and 2.29 eV for 2D monolayer and 1D nanochain, endow low-dimensional Ga3Te3I materials with promising visible light-harvesting capability and charge carrier mobility. And the electronic properties can be effectively adjusted by the applied strain. Interestingly, 1D Ga3Te3I nanochain exhibits superior mechanical elasticity, which is comparable to those of most reported 1D materials. These highly desirable properties make low-dimensional Ga3Te3I materials reliable candidates in future electronic, optoelectronic, and photovoltaic devices.

Published: June 2022

Abstract
Failure analysis (FA) was encountered as a ion charging risk when using focused ion beam to insert extra test pads for mixed signal integrated circuits (IC) on silicon on insulator (SOI). To overcome this challenge, and to precisely locate the open circuit defect, this paper described an effective non-destructive FA method based on dynamic InGaAs photon emission microscopy and schematic/layout analysis to determine the open circuit type and position. Nano-probing and electron beam absorbed current was used to located the precise location of the open circuit defect. Two typical samples of mixed signal IC on SOI were used (Samples 1 and 2, with extra and missing emission spots, respectively) to illustrate the analysis procedure and effectiveness for the proposed method. Scanning electron microscope results were presented to verify the accuracy of this method. It was demonstrated that the proposed method was able to accurately determine failure of open circuit efficiently without microprobe for mixed signal IC on SOI.

Abstract
Metal thio(seleno)phosphates MPX3 have attracted considerable attentions with wide spanned band gaps and rich magnetic properties. In this series, two neighboring members MnPS3 and NiPS3 differ in magnetic atoms, magnetic easy axes, spin anisotropy, as well as nearest-neighbor magnetic interactions. The competition between these components may cause intriguing physical phenomena. In this article, the evolution of magnetism of Mn1−x
Ni
x
PS3 series is reported. Despite the incompatible antiferromagnetic orders of two end members, the antiferromagnetism persists as the ground state in the whole substitution region. The magnetic ordering temperature T
N show nonmonotonic V-shape behavior, and the reentrant spin glass phase at x= 0.5 is observed. In addition, abnormal bifurcation of T
N occurs at x = 0.75, which may be due to the temperature-dependent spin reorientation or phase separation. The evolution of magnetism is further confirmed semi-quantitatively by our density functional theory calculations. Our study indicates that exotic magnetism can be intrigued when multi-degrees of freedom are involved in these low-dimensional systems, which call for more in-depth microscopic studies in future.
