Unconventional hidden Rashba effects in two-dimensional InTe
Authors: Lee Sangmin , Kim Miyoung , Kwon Young-Kyun 
Published: June 2023

AbstractMuch attention has been paid to the hidden Rashba effect exhibiting an intriguing spin-layer locking phenomenon observed in two-dimensional materials with inversion symmetry. This effect provides a new possibility for manipulating Rashba spin polarization even in centrosymmetric materials. We propose a mechanism exhibiting an unconventional hidden Rashba effect showing a unique helical spin texture in which two Fermi circles in different bands have the same spin helicity exhibiting a complete spin separation in space. We demonstrate such an unconventional hidden Rashba effect by showing the unique electronic structures of two-dimensional InTe with inversion symmetry investigated by the first-principles calculations. It is found that spins in both the inner and outer bands with the one helicity are located in the top sublayer whereas spins with the other helicity are in the bottom sublayer indicating a complete spatial spin separation. Strong spin-orbit coupling and a band inversion among two pairs of spin-degenerate bands are the main origins for the unconventional hidden Rashba involving two pairs of spin-degenerate bands rather than one pair, which gets usually involved in the conventional (hidden) Rashba effects. This new type of the hidden Rashba effect observed in two-dimensional InTe would broaden our understanding of the underlying physics of spin polarization phenomena eventually leading to a potential application in future spintronics.

AbstractThe use of renewable energy is central for the realization of a circular economy, which is essential for further global economic development. In this background, hydrogen storage materials play an important role. Here we propose a previously overlooked, industrially available bulk chemical (methyl formate, MF) as an efficient and practical hydrogen storage material. Utilizing appropriate catalysts, hydrogen production from MF is significantly faster than with other established chemical hydrogen carriers, such as formic acid and methanol, under very mild conditions. The optimized MF dehydrogenation system presented here is highly active (maximum turnover frequency (TOFmax) > 44,000 h−1 and turnover number > 100,000) and selective (CO undetectable). Moreover, the solvent-free MF dehydrogenation demonstrates its application potential. Here we show the dehydrogenation reaction of MF. We expect that these insights will serve as an inspiration for the development of alternative energy materials and new catalytic transformations.
Protéger l’environnement pour se gouverner ? Repolitiser les « subjectivités environnementales » dans les aires protégées (San Andrés, Colombie)
Authors: Berthod Justine 
Published: June 2023

L’article discute la notion de « subjectivités environnementales » d’Arun Agrawal. Elle permet d’analyser la construction d’identités environnementales dans l’évolution des relations entre l’État et ses marges. Nous proposons d’appliquer la notion à l’appropriation conflictuelle de la conservation par les pêcheurs de la réserve de biosphère Seaflower (Colombie). L’article propose d’illustrer la pluralité des « subjectivités environnementales » qui naissent de dispositifs de conservation peu participatifs, au cœur des contradictions de la conservation bioculturelle. Il remet en question la subjectivation environnementale comme adoption d’un environnementalisme consensuel. Il décrira plutôt un processus social contraint et conflictuel – finalement, politique – de redéfinition des bons usages de la nature.
Die Lebendigkeit des Selbst – das gesunde
Immunsystem

Published: June 2023

ZusammenfassungDie osteopathische Behandlung des Immunsystems, prophylaktisch, regenerativ nach einer
Infektion, ausgleichend nach Impfreaktionen oder unterstützend bei Long Covid,
ist wieder aktuell. Eine gute Funktion des Immunsystems bedeutet, zuerst das Selbst zu
erkennen und sich dann vom Nicht-Selbst abzugrenzen oder sich zu verteidigen. Die
Komplexität des Immunsystems führt zu verschiedensten therapeutischen
Ansätzen. Durch diese können wir das Immunsystem nicht nur in seiner
gesamten Funktion erfassen, sondern es bei der (Wieder-)Herstellung eines funktionalen
Gleichgewichts begleiten. Die Auswirkungen sind enorm, ist doch die Entität des
Patienten in ihrem fluiden Ganz-Sein innerhalb der Grenzen des Selbst und in ihrer
Lebendigkeit in der Lage, sich vollkommen neu zu orientieren. So kann im gesamten
zellulären Kontinuum und darüber hinaus Gesundheit entfaltet und eine
(neue) Integrität stabilisiert werden.

Switching Regioselectivity in the Asymmetric Bromocyclization of Difluoroalkenes Catalyzed by a Chiral Bisphosphine Oxide

Published: June 2023

AbstractWe present an efficient approach for the enantioselective synthesis of difluoromethylene-containing oxazine compounds through 6-endo-selective bromocyclization of difluoroalkenes by using a chiral proton-bridged bisphosphine oxide complex as a catalyst precursor. The regioselectivity is significantly influenced by the solvent and the catalyst structure, and 6-endo cyclization products can be obtained preferentially with moderate to high enantioselectivity. This protocol offers complementary regioselectivity to our previously reported 5-exo-selective reaction, permitting the synthesis of diverse medicinally interesting compounds.

Abstract
Purpose To assess the reproducibility (i.e., inter-device reliability) of the biometers Topcon MYAH, Oculus Myopia Master, and Haag-Streit Lenstar LS900 with the Carl Zeiss IOLMaster
700 and the intra-subject repeatability in myopic children in order to reliably detect axial growth for myopia management.
Methods Twenty-two myopic children (11.1 ± 2.4 yr) with a spherical equivalent of − 3.53 ± 2.35 D were examined with each of the biometers to assess axial length (AL) and corneal
parameters (steepK, flatK, meanK, vectors J0, J45), and16 of these children agreed to a second round of measurements. Reproducibility of the first measurements between the IOLMaster and
every other biometer was assessed employing a Bland-Altman approach and paired Studentʼs t-test. Repeatability was assessed as intra-subject standard deviation and was used to estimate the
minimum time interval required between two AL measurements to reliably detect axial growth of an eye of at least 0.1 mm/year.
Results Repeatability for AL measurements was as follows: IOLMaster: 0.05 mm, Myopia Master: 0.06 mm, Myah: 0.06 mm, Lenstar: 0.04 mm; the respective minimal time interval for axial
growth assessment in myopia management was estimated as 5.6, 6.6, 6.7, and 5.0 months, respectively. Best reproducibility of the AL measurement was found between IOLMaster and Lenstar [95%
Limits of Agreement (LoA) for reproducibility − 0.06 to 0.02]. As regards to the measured means, Lenstar gave measures of AL that were longer than with the IOLMaster by 0.02 mm
(p < 0.001). Myopia Master measures of meanK were significantly lower (by 0.21 D with p < 0.001) than the values from the IOLMaster. As for J0, all biometers deviated significantly
from IOLMaster measurements (p < 0.05).
Conclusion Generally good agreement was observed between all the biometers. When assessing myopia progression in children, a time frame of at least 6 months between the AL
measurements is advisable in order to reliably determine any deviation from a normal growth pattern.
Pd-Catalyzed Homologation of Arylboronic Acids as a Platform for the Diversity-Oriented Synthesis of Benzylic C–X Bonds
Authors: Watson Allan J. B. , Bastick Kane A. C. 
Published: June 2023

AbstractWe report a synthetic platform for the formation of benzylic C–X bonds. Benzylboronic acid pinacol (Bpin) esters are useful synthetic intermediates but are commercially uncommon, leading to preparations that typically rely upon stoichiometric metalation. Pd-catalyzed formal homologation of arylboronic acids provides access to these compounds that, in turn, allow the formation of C–C, C–O, and C–N bonds from Pd- and Cu-mediated cross-coupling or oxidative processes. This affords a wide variety of benzylic alcohols, diarylmethanes, benzyl amines, and benzyl ethers. Limitations are disclosed, and the utility is further demonstrated by the generation of analogues of meclizine.

AbstractThe organocatalyst cinchonidine-squaramide was immobilized within three different deep eutectic solvents (DESs): betaine:d-sorbitol:water, betaine: d-xylitol:water, and betaine:d-mannitol:water and evaluated in a well-known asymmetric Michael addition. These reactions provided excellent yields (up to 99%) and enantioselectivities (up to 98%) using only 1 mol% of organocatalyst. It was also possible to achieve 9 cycles in reactions with DES (betaine:d-sorbitol:water), proving the high recyclability of this system. In the reactions realized with only 0.5 mol% of organocatalyst, it was possible to achieve 5 cycles, and the products were obtained with high yields (up to 95%) and excellent enantioselectivities (up to 94%), using DES (betaine:d-sorbitol:water).

Abstract
Background Pre-diabetes (PD) contributes importantly to the disease burden worldwide and is a precursor to stroke, cardiovascular diseases, as well as type-2 diabetes mellitus.
Objective In this project, the efficacy of individualized homeopathic medicines (IHMs) was explored against placebos in the treatment of PD.
Methods A 6-month, double-blind, randomized, placebo-controlled trial was conducted at the outpatient departments of a homeopathic medical college and hospital in India. Sixty participants with PD were randomized to receive either IHMs (n = 30) or identical-looking placebos (n = 30). Concomitant care measures were advised to both groups of participants in terms of dietary advice, yoga, meditation and exercise. The primary outcome measures were fasting blood sugar (FBS) and the oral glucose tolerance test (OGTT); the secondary outcome was the Diabetes Symptom Checklist-Revised (DSC-R) score. All the outcomes were measured at baseline and after 3 and 6 months of treatment. Inter-group differences and effect sizes (Cohen's d) were calculated using two-way repeated measures analysis of variance models after adjusting baseline differences using analysis of co-variance on the intention-to-treat data.
Results Between-group differences for FBS were statistically significant, favoring IHMs against placebos (F
1,58 = 7.798, p = 0.007), but not for OGTT (F
1,58 = 1.691, p = 0.199). The secondary outcome, DSC-R total score, favoring IHMs significantly compared with placebos (F
1,58 = 15.752, p < 0.001). Calcarea Carbonicum, Thuja occidentalis and Sulphur were the most frequently prescribed medicines. No harm or serious adverse events were recorded from either of the participant groups.
Conclusion IHMs produced significantly better results than placebos in FBS and in DSC-R scores but not in OGTT. Independent replications with larger sample sizes are warranted to substantiate the findings.

We present a laser-driven, bright, and broadband (50 to 1500 eV) soft-x-ray plasma source with &lt;10 ps pulse duration. This source is employed in two complementary, laboratory-scale beamlines for time-resolved, magnetic resonant scattering and spectroscopy, as well as near-edge x-ray absorption fine-structure (NEXAFS) spectroscopy. In both beamlines, dedicated reflection zone plates (RZPs) are used as single optical elements to capture, disperse, and focus the soft x rays, reaching resolving powers up to E/ΔE &gt; 1000, with hybrid RZPs at the NEXAFS beamline retaining a consistent E/ΔE &gt; 500 throughout the full spectral range, allowing for time-efficient data acquisition. We demonstrate the versatility and performance of our setup by a selection of soft-x-ray spectroscopy and scattering experiments, which so far have not been possible on a laboratory scale. Excellent data quality, combined with experimental flexibility, renders our approach a true alternative to large-scale facilities, such as synchrotron-radiation sources and free-electron lasers.
Dynamical approach to the atomic and electronic structures of the ductile semiconductor Ag2S

Published: June 2023

Silver sulfide in monoclinic phase (α-Ag2S) has attracted significant attention owing to its metal-like ductility and promising thermoelectric properties near room temperature. However, first-principles studies on this material by density functional theory calculations have been challenging as both the symmetry and atomic structure of α-Ag2S predicted from such calculations are inconsistent with experimental findings. Here, we propose that a dynamical approach is imperative for correctly describing the structure of α-Ag2S. The approach is based on a combination of ab initio molecular dynamics simulation and deliberately chosen density functional considering both proper treatment of the van der Waals interaction and on-site Coulomb interaction. The obtained lattice parameters and atomic site occupations of α-Ag2S are in good agreement with experimental data. A stable phonon spectrum at room temperature can be obtained from this structure, which also yields a bandgap in accord with experimental measurements. The dynamical approach thus paves the way for studying this important ductile semiconductor in not only thermoelectric but also optoelectronic applications.

Published: June 2023

The use of lung ultrasound (LUS) in clinical settings is emerging as an important tool in the assessment of lung pathology and/or function and has gained considerable acceptance. LUS is being integrated into clinical care by trained respiratory physiotherapists and has been shown to influence physiotherapists’ clinical decision-making in the respiratory management of patients. Considering the use of LUS by physiotherapy is in its infancy and still evolving, there is likely variability in the ability and confidence of physiotherapists to use LUS in clinical practice, both in Australia and internationally. While the UK has had a rapid increase in the number of LUS-accredited physiotherapists (n = 111), the number of LUS-accredited physiotherapists in Australia remains very low (n = 4). There is a growing body of work in the UK on physiotherapy-led LUS in respiratory care, however, there is currently little work published on the practicalities of training and establishing physiotherapy-led LUS in Australia. This report describes the training and implementation of physiotherapy-led LUS in the intensive care unit from a regional hospital perspective.
Rubber-like elasticity in laser-driven free surface flow of a Newtonian fluid
Authors: Kayanattil Meghanad , Huang Zhipeng , Gitaric Djordje , Epp Sascha W.

The energy needed to deform an elastic solid may be recovered, while in Newtonian fluids, like water and glycerol, deformation energy dissipates on timescales of the intermolecular relaxation time

the existence of shear elasticity requires long-range correlations, which challenge our understanding of the liquid state. We investigated laser-driven free surface bubbles in liquid glycerol by analyzing their expansion and bursting dynamics, in which we found a flow-dominating, rubber-like elasticity unrelated to surface tension forces. In extension to findings of a measurable liquid elasticity at even very low deformation frequencies [L. Noirez, P. Baroni,

Published: June 2023

Summary
This case study focuses on the gay tourism industry in Gran Canaria and Sitges. These destinations in Spain offer a niche of service organizations intended for and marketed to gay customers. It discusses the sexualization and commodification of employees’ appearance (also known as sexualized aesthetic labour) and sexual harassment by customers. Specifically, the case study presents the experiences of hospitality workers, focusing mainly on migrant workers of colour, whose appearance and racial characteristics are commodified by employers to attract customers. This process of commodification leads to customers subsequently harassing employees leading to widespread third-party sexual harassment.

Reaction mechanism for atmospheric pressure plasma treatment of cysteine in solution
Authors: Polito Jordyn , Herrera Quesada María J , Stapelmann Katharina , Kushner Mark J 
Published: June 2023

Abstract
Mechanisms for the cold atmospheric plasma (CAP) treatment of cells in solution are needed for more optimum design of plasma devices for wound healing, cancer treatment, and bacterial inactivation. However, the complexity of organic molecules on cell membranes makes understanding mechanisms that result in modifications (i.e. oxidation) of such compounds difficult. As a surrogate to these systems, a reaction mechanism for the oxidation of cysteine in CAP activated water was developed and implemented in a 0-dimensional (plug-flow) global plasma chemistry model with the capability of addressing plasma-liquid interactions. Reaction rate coefficients for organic reactions in water were estimated based on available data in the literature or by analogy to gas-phase reactions. The mechanism was validated by comparison to experimental mass-spectrometry data for COST-jets sustained in He/O2, He/H2O and He/N2/O2 mixtures treating cysteine in water. Results from the model were used to determine the consequences of changing COST-jet operating parameters, such as distance from the substrate and inlet gas composition, on cysteine oxidation product formation. Results indicate that operating parameters can be adjusted to select for desired cysteine oxidation products, including nitrosylated products.
Third-order square-root topological insulators on decorated diamond sonic crystals

Published: June 2023

Abstract
The square-root operation can generate novel topological phases, whose nontrivial topological properties are inherited from the parent Hamiltonian. Here we report the acoustic realization of third-order square-root topological insulators by adding additional resonators between the site resonators of original diamond lattice. Due to the square-root operation, multiple acoustic localized modes appear in doubled bulk gaps. The bulk polarizations of the tight-binding models are employed to reveal the topological feature of the higher-order topological states. By tuning the coupling strength, we find the emergence of third-order topological corner states in doubled bulk gaps on tetrahedron-like and rhombohedron-like sonic crystals, respectively. The shape dependence of square-root corner states provides an extra degree of freedom for flexible manipulation on the sound localization. Furthermore, the robustness of the corner states in three-dimensional (3D) square-root topological insulator is well elucidated by introducing random disorders into the irrelevant bulk region of the proposed 3D lattices. This work extends square-root higher-order topological states into 3D system, and may find possible applications in selective acoustic sensors.
