AbstractObjectiveAutonomic dysfunction is an independent risk factor for cardiovascular disease (CVD). Both obesity and obstructive sleep apnea (OSA) are associated with heart rate variability (HRV) (a hall marker of sympathetic arousal) and increased risk of CVD. This study aims to investigate whether anthropometric parameters could predict reduced HRV in adult OSA during wakefulness.Study DesignCross‐sectional study.SettingSleep center of Shanghai Jiao Tong University Affiliated Sixth Hospital from 2012 to 2017.MethodsTotal of 2134 subjects (503 non‐OSA and 1631 OSA) were included. Anthropometric parameters were recorded. HRV was recorded during a 5‐minute wakefulness period and analyzed by using time‐domain method and frequency‐domain method. Multiple step‐wise linear regressions were performed to determine significant predictors of HRV with and without adjustments. Multiplicative interactions between gender, OSA, and obesity on HRV were also determined and evaluated.ResultsWaist circumference (WC) was significant negative determinant of root mean square of successive NN intervals (β = −.116, p < .001) and high‐frequency power (β = −.155, p < .001). Age was the strongest determining factor of HRV. Significant multiplicative interactions between obesity and OSA on HRV, gender, and obesity on cardiovascular parameters were observed.ConclusionAnthropometric parameters could predict reduced HRV during wakefulness in patients with OSA, especially WC was the strongest influenceable factor. Obesity and OSA had significant multiplicative interaction on HRV. Gender and obesity had significant multiplicative interaction on cardiovascular parameters. Early intervention for obesity, especially centripetal obesity, may improve reduction of autonomic function and risk of CVD.

AbstractDurability on the transverse shear properties of hybrid fiber‐reinforced polymer (HFRP) bar may control the cross‐sectional load‐bearing capacity and failure mode of the HFRP bar reinforced concrete members due to its strength degradation with time. Herein, the degradation of novel carbon/glass (C/G)‐HFRP bars were accelerated in simulated concrete environments at 60°C to investigate the effects of fiber volume fraction and distribution pattern, matrix resin volume fraction, exposure environment, and period on their transverse shear properties. The results displayed that the transverse shear strength of the samples reduced by 15%, 20%, and 8% after exposure to the simulated ordinary concrete, seawater sea‐sand concrete environments, and tap water for 6 months, respectively. The inward diffusion of water molecules and free hydroxyl ions caused the hydrolysis of matrix resin, etching of glass fiber and debonding of fiber/matrix interface, which were the incentives of the degradation of C/G‐HFRP bars. The increase of matrix resin volume fraction and the application of a waterproof coating were recommended to alleviate the degradation of fibrous composites in concrete environments. Finally, two prediction models were proposed to determine the transverse shear strength of HFRP bar before and after exposure to different harsh environments, respectively. The comparisons indicated that the predicted values were coincided with the experimental results.

AbstractIntroductionGlabridin is a unique isoflavonoid found only in Glycyrrhiza glabra L. The pharmacological effects of glabridin are well established, especially for beauty‐ and wellness‐related uses, such as antioxidant, anti‐inflammatory, ultraviolet (UV) protection, and skin‐lightening effects. Therefore, glabridin is often found in commercial products such as creams, lotions, and dietary supplements.ObjectiveThis study aimed to develop an enzyme‐linked immunosorbent assay (ELISA) using a glabridin‐specific antibody.MethodImmunogen conjugation of glabridin‐bovine serum albumin was performed via the Mannich reaction, and the resulting conjugates were injected into BALB/c mice. Subsequently, hybridomas were produced. An ELISA method for glabridin determination was developed and validated.ResultA highly specific antibody against glabridin was produced using clone 2G4. The assay range for the determination of glabridin was 0.28–7.02 μg/ml, with a detection limit of 0.16 μg/ml. The validation parameters in terms of accuracy and precision met the acceptable criteria. Standard curves of glabridin in various matrices were compared to evaluate the matrix effect on human serum using ELISA. Standard curves of the human serum and water matrix were obtained in the same manner, and the measurement range was 0.41–10.57 μg/ml.ConclusionThe developed ELISA method was used to quantify glabridin in plant materials and products with high sensitivity and specificity, and has potential applications in quantifying compounds in plant‐derived products and human serum samples.
National markets in a world of global platform giants: The persistence of Russian domestic competitors
Authors: Kontareva Alina , Kenney Martin 
Published: May 2023

AbstractUS platform companies have dominated the global platform economy. Drawing on archival research, interviews, and company reports, we explore the reasons that Russia was able to develop platform companies that survived the entry of US firms. The chaotic post‐Soviet society paradoxically provided a sheltered environment within which domestic companies could build sufficient competence to maintain their domestic market position. As first movers, Russian companies created and leveraged within‐country network effects based on social, cultural, and physical affinities with their user base. This made it difficult for US platforms to overwhelm domestic companies. After 2008, the Russian government's position regarding the internet changed, and it began to selectively shield domestic leaders by preventing acquisitions by foreign companies and requiring the preloading of domestic applications on devices. Our Russian case study is instructive for other countries that want to remain open but, at the same time, build domestic platform companies.

Published: May 2023

AbstractLarge amount of carbon emission is the main hazard to environment and human health. The aim of this research is to investigate the impact of economic growth, forest zone, agricultural productivity, and energy consumption on environmental pollution in China using time series data from 1980 to 2020. The underline research utilized dynamic ordinary least‐squares (DOLS) method, Johansen and Engle–Granger cointegration tests, and the autoregressive‐distributed lag (ARDL) technique to analyze the varying data set. To compare findings, fully modified ordinary least squares (FMOLS) and canonical cointegrating regression (CCR) estimators are estimated. Energy use and population raise CO2 emissions with 1% economic development. Long‐term CO2 emissions may be reduced by 1% agriculture production and forestry zone growth. The Granger causality test showed causation between all variables. Results reveal that China might achieve sustainable development goals by cutting down CO2 emissions and mitigate global climate change. The underline research presents policy recommendations for attaining environmental sustainability in China through green investment by reducing carbon emissions. These policies highlight promoting use of renewable energy, financing green technological progression in agricultural productivity, and the ecological feasibility of China's forests.
Textures of value: Tactility, experience, and exclusion in the cashmere commodity chain
Authors: Graber Kathryn E. 
Published: May 2023

ABSTRACTCashmere provides an ideal material for examining how humans co‐opt tangible and intangible qualities into their ascription of value. The fiber's relative worth lies at the intersection of its tangible qualities (e.g., softness, lightness, strength) and intangible qualities (e.g., rarity, history, authenticity, sustainability). Mediating the relationship between those qualities are actors with very different stakes: the families of Mongolian herders who comb goats together each spring, the brokers and buyers who weigh it and feel it to adjudicate it for fashion houses, and the advertisers and marketers who decide what is desirable in global markets of end consumers. This article examines three nodes in the production and circulation of Mongolian cashmere to show how different forms of value—economic, social, linguistic, moral—accrue to material goods and travel, or not, from one context to another. I focus on interactions as moments of qualic evaluation. Here embodied, tactile experiences of qualia—which might seem to be immune to perceptual difference and “outside culture”—in fact differ. The example shows how valuation in a transnational commodity chain depends on both exploiting semiotic gaps in the chain and nonetheless meeting a threshold of commensurability, neither of which is divorceable from physicality.

Authors: Formisano Antonio , Felitti Matteo , Oliveto Francesco , Mendicino Lorenzo 
Published: May 2023

AbstractThe robustness of a structural systems is understood as their ability to prevent or reduce the consequences of a local (exceptional and/or extreme) event. The current work aims to address the issues related to the evaluation of robustness of structures with incorporated damage. The case study of an existing reinforced concrete arch bridge is investigated in terms of robustness considering the variation of both the cracking state from concrete spalling and the corrosion of reinforcement bars. The damage variation related to these different matters is assessed both in terms of intensity and occurrence in the various structural elements of the bridge. Finally, the structural robustness index is estimated through push‐down analysis to make an overall assessment of the bridge behavior.

AbstractAs a striking contribution of metakaolin to geopolymer concretes, the varying contents of metakaolin with quartz powder are included the mixtures with ground granulated blast furnace slag, and quartz sand to observe the mechanical, physical, transport, microstructure, and nuclear protection parameters of the samples, within this study. The geopolymer concrete samples are tested for the mechanical transport and physical properties depending on the curing time, curing temperature, and the raw/by‐product material type. The results show that the samples containing the most metakaolin performed well with a 24‐h compressive strength of 131.78 MPa. Increasing the curing temperature and curing time affected both mechanical, physical and transport properties. In addition, the microstructure of the samples was analyzed by scanning electron microscopy, x‐ray diffraction, and Fourier transform infrared spectroscopy. Moreover, the effect of increasing metakaolin reinforcement on the nuclear protection capacity of the produced geopolymer concretes with experimental gamma transmission and neutron dose measurements was investigated. The M3 sample with high content of both metakaolin and granulated blast‐furnace slag showed the highest resistance to gamma photons in the energy range of 0.081–0.383 MeV. The produced geopolymer samples absorbed almost 40% of the fast neutrons with 4.5 MeV energy. Neutron removal cross sections of the produced geopolymer concretes are in the range of 0.0952–0.0949 cm−1 and are larger than those of B4C, graphite, and boric acid. The findings of this study revealed that the addition of metakaolin improved the mechanical, nuclear shielding and structural properties of geopolymer concretes.
Arch Action Model for the structural assessment of existing prestressed concrete bridges
Authors: Gleich Philipp , Maurer Reinhard 
Published: May 2023

AbstractStructural assessments of existing older prestressed concrete bridges according to the currently applicable standards and guidelines in Germany generally reveal significant deficiencies in shear reinforcement. Large‐scale tests within the scope of research activities commissioned by the Federal Highway Research Institute (BASt) were carried out at TU Dortmund University to analyze the shear load‐bearing behavior of continuous prestressed concrete beams in more detail. The Arch Action Model (AAM) was derived from the Simplified Arch Action Model (SAAM) to provide a possible analysis method for determining shear contribution from concrete. Thus, the shear capacity of prestressed beams can be determined in a more realistic manner than using the truss model underlying the current state of standardization. The paper at hand provides information and explanations about the SAAM and AAM with regard to their application to real‐world structures for structural bridge assessments.

AbstractBackgroundCanine parvovirus type 2 (CPV‐2) is known as the primary etiological agent cause of acute gastroenteritis, myocarditis and death of canids worldwide. In Vietnam, although CPV‐2 infection and its outbreaks are the most important risk factors of the canine's health concern, lack of available information about the molecular epidemiology of the CPV‐2.ObjectivesIn this study, the complete coding sequences of 10 CPV‐2 strains collected from dogs vaccinated with CPV‐2 vaccination were analysed to better understand the genomic characteristics of the current circulating CPV‐2 in Vietnam.MethodsTen CPV‐specific PCR‐positive rectal swab samples were collected from dogs with acute symptoms of haemorrhagic diarrhoea and vomiting in Vietnam in 2019. The complete coding sequences of these CPV strains were analysed to determine their phylogeny and genetic relationship with other available CPV strains globally.ResultsAnalysis of the VP2 gene sequences demonstrated that the studied strains belonged to the new CPV‐2c variants with the unique mutations at amino acids 5Ala‐Gly and 447Iso‐Met. Phylogenetic tree analysis indicated that the studied strains share a common evolutionary origin with the current CPV‐2c strains circulating in dogs in Asia countries, including China, Thailand, Taiwan and Mongolia, in recent years. Low sequence identity between the studied strains and commercial vaccine strains was observed.ConclusionsThis study provides deep insights into the molecular characteristics, genetic diversity, and evolution of circulating CPV‐2 strains in Vietnam. We recommend more studies to estimate the effectiveness of the CPV vaccine and the need to continue developing other effective vaccination essential to better control the widespread of these new CPV‐2 variants.
Rheological behavior and thermomechanical properties of polyethylene—Glycidyl methacrylate vitrimers utilizing disulfide exchange
Authors: Lossen Amy , Montoya‐Ospina Maria Camila , Verhoogt Henk , Osswald Tim A. 
Published: May 2023

AbstractFour vitrimers were made using polyethylene – glycidyl methacrylate copolymer (PE‐GMA) and 3,3′ – dithiodipropionic acid (DTDPA) using a two‐step procedure. The amount of DTDPA added was varied, and therefore, the crosslink density was also varied. Rheological experiments were performed. The vitrimers exhibit different rheological behavior depending on the angular frequency applied, which most likely stems from the presence of a crosslinked network. Additionally, there appears to be an on‐going reaction occurring during rheological tests, all of which occur above the melting temperature. Thermal and mechanical tests were also conducted. Thermomechanical testing determined that increasing crosslink density resulted in a decrease in the yield strength.

AbstractA 10‐year‐old, 8.9‐kg, spayed, female Jack Russell Terrier, with previously well‐controlled diabetes mellitus, presented with hyporexia of 2‐day duration. Cranial abdominal pain and weight loss were detected on clinical examination. Blood tests, urinalysis, urine protein:creatinine ratio, blood pressure, abdominal ultrasound and liver aspirate cytology revealed hyperglycaemia, elevated serum liver enzyme activities, glucosuria, proteinuria, hypertension, rounded liver edges, irregular hyperechoic gall bladder wall thickening, irregular hyperechoic gall bladder content and vacuolar hepatopathy. Bile cytological examination demonstrated fungal organisms, which were identified asCandida albicanson bile fungal culture. No bacteria were detected on bile cytological examination or bile bacterial aerobic and anaerobic culture. The dog was diagnosed withCandida albicanscholecystitis and recovered after a 12‐week course of oral ketoconazole. This case report highlights the value of performing bile cytology in suspect canine cholecystitis cases and is the first to describeCandida albicansfungal cholecystitis without bacterial coinfection in dogs.
In situ encapsulation of laccase in mesoporous amorphous ZIF‐8 for Reactive Blue 19 removal
Authors: Shi Yao , Xing Yifei , Gong Changbao , Zhao Huimin 
Published: May 2023

AbstractLaccase with substrate non‐specificity is particularly effective in pollutant degradation. However, the practical application of the laccase is limited due to its poor stability and reusability. In this study, a simple in situ encapsulation method was used to immobilize laccase into amorphous zeolitic imidazolate frameworks‐8 (aZIF‐8), and the synthesized Lac@aZIF‐8 biocomposites were used to remove Reactive Blue 19 (RB 19). Results indicated that the presence of mesoporous endowed the immobilized laccase with higher substrate affinity. Compared with free laccase, the Lac@aZIF‐8 showed higher thermo‐tolerant performance, wider pH range, better storage stability, and reusability. The Lac@aZIF‐8 biocomposites have excellent performance in the effective removal of RB 19. Without any mediators, the dye decolorization rate of immobilized laccase reached up to 82% in 3 h under optimal conditions. Based on the LC‐MS analysis, the proposed degradation pathways of RB 19 were discussed technically. Moreover, the growth inhibition experiments on Scenedesmus obliquus confirmed the lower toxicity intensity of the degradation products. This research enhanced the stability of laccase while maintaining high substrate affinity, providing a novel strategy for the green and efficient treatment of dye wastewater.Practitioners Points

The hMSSM with a light gaugino/higgsino sector: implications for collider and astroparticle physics

Published: May 2023

Abstract
The hMSSM is a special parameterization of the minimal supersymmetric extension of the Standard Model (MSSM) in which the mass of the lightest Higgs boson is automatically set to the LHC measured value, Mh=125 GeV, by adjusting the supersymmetric particle spectrum such that it provides the required amount of radiative corrections to the Higgs boson masses. The latter spectrum was in general assumed to be very heavy, as indicated by the present exclusion limits of the LHC, not to affect the phenomenology of the Higgs sector. In this work, we investigate the impact on the hMSSM by a light gaugino and higgsino sector, that is allowed by the present LHC data. In particular, we discuss the radiative corrections due to charginos and neutralinos to the Higgs boson masses and couplings and show that an hMSSM can still be realized in this context. We first describe how this scenario is implemented in the package SuSpect that generates the MSSM Higgs and supersymmetric spectra. We then analyze the possible impact of Higgs boson decays into these new states, as well as the reverse cascade channels with Higgs bosons in the final states, for the constraints on the MSSM Higgs sector at the LHC. We further explore the cosmological constraints on the hMSSM with a light gaugino-higgsino spectrum. We analyze the relic abundance of the lightest neutralino as a candidate of the dark matter in the Universe and the constraints on its mass and couplings by the present and future astroparticle physics experiments.
More ingredients for an Altarelli cocktail at MiniBooNE
Authors: Kelly Kevin J. , Kopp Joachim 
Published: May 2023

Abstract
The MiniBooNE excess persists as a significant puzzle in particle physics. Given that the MiniBooNE detector cannot discriminate between electron-like signals and backgrounds due to photons, the goal of this work is to study photon backgrounds in MiniBooNE in depth. We first consider a novel single-photon background arising from multi-nucleon scattering with coherently enhanced initial or final state radiation. This class of processes, which we dub “2p2hγ” (two-particle–two-hole + photon) can explain ~40 of the ~560 excess events observed by MiniBooNE in neutrino mode. Second, we consider the background from neutral-current single-π0 production, where two photons from π0 → γγ decay are mis-identified as an electron-like shower. We construct a phenomenological likelihood that reproduces MiniBooNE’s π0 → γγ background faithfully. Even with data-driven background estimation techniques, we find there is a residual dependence on the Monte Carlo generator used. Our results motivate a reduction in the significance of the MiniBooNE excess by 0.4σ.
