AbstractWearable technology applications have experienced remarkable development and advancements, with soft and stretchable strain sensors playing a significant role in this progress. Despite the promising potential of combed‐shaped interdigital capacitive strain sensors in wearable electronics, several challenges exist, including limited stretchability, universal mass fabrication, and seamless integration into diverse clothing parts. This study presents a textile knitted interdigital capacitive sensor that incorporates stretchable conductive yarn, produced using textile twisting technology, to achieve stretchability and adaptability, allowing seamless conformation to human body movements and textile materials. The fabrication process involves embedding the interdigital electrodes and interconnections directly into the fabric through textile knitting technology, ensuring robust integration. Furthermore, this work presents opportunities for commercializing the stretchable interdigital strain sensor through a low‐cost and mass production strategy. Electromechanical characterization demonstrates exceptional performance with high stretchability (≈230%), excellent linearity (R2 = 0.997), a gauge factor (GF) of −0.68 representing relative capacitance change, and a rapid response time of 66 ms. To validate the usability of sensors in wearable technology, a knee brace application is employed to investigate capacitance changes during walking and cycling exercises. This approach will accelerate the accessibility of wearable stretchable interdigital sensors for all.
A Note on Bias Correction for the Standard Two‐Sided Power Distribution
Authors: Lemonte Artur J. 
Published: October 2023

AbstractIt is verified that the maximum likelihood (ML) estimators of the standard two‐sided power distribution (STSP) parameters introduced by van Dorp and Kotz on the interval (0,1) can be severely biased. Since the usual analytical methods of bias correction cannot be applied in such a parametric distribution, bootstrap bias correction methods are proposed. The numerical study favors a particular bootstrap estimator based on parametric resampling. Real data applications are also considered to illustrate the impact of bias correction of the usual maximum likelihood estimators of the standard two‐sided power distribution parameters when the sample size is small.

AbstractMacrophage efferocytosis of apoptotic osteoblasts (apoOBs) is a key osteoimmune process for bone homeostasis. However, apoOBs frequently accumulate in aged bone marrow, where they may mount proinflammatory responses and progressive bone loss. The reason why apoOBs are not cleared during aging remains unclear. In this study, it is demonstrated that aged apoOBs upregulate the immune checkpoint molecule CD47, which is controlled by SIRT6‐regulated transcriptional pausing, to evade clearance by macrophages. Using osteoblast‐ and myeloid‐specific gene knockout mice, SIRT6 is further revealed to be a critical modulator for apoOBs clearance via targeting CD47‐SIRPα checkpoint. Moreover, apoOBs activate SIRT6‐mediated chemotaxis to recruit macrophages by releasing apoptotic vesicles. Two targeting delivery strategies are developed to enhance SIRT6 activity, resulting in rejuvenated apoOBs clearance and delayed age‐related bone loss. Collectively, the findings reveal a previously unknown linkage between immune surveillance and bone homeostasis and targeting the SIRT6‐regulated mechanism can be a promising therapeutic strategy for age‐related bone diseases.

AbstractAfterglow room‐temperature emission that is independent of autofluorescence after ceasing excitation is a promising technology for state‐of‐the‐art bioimaging and security devices. However, the low brightness of the afterglow emission is a current limitation for using such materials in a variety of applications. Herein, the continuous formation of condensed triplet excitons for brighter afterglow room‐temperature phosphorescence is reported. (S)‐(‐)‐2,2′‐Bis(diphenylphosphino)‐1,1′‐binaphthyl ((S)‐BINAP) incorporated in a crystalline host lattice showed bright green afterglow room‐temperature phosphorescence under strong excitation. The small triplet–triplet absorption cross‐section of (S)‐BINAP in the whole range of visible wavelengths greatly suppressed the deactivation caused by Förster resonance energy transfer from excited states of (S)‐BINAP to the accumulated triplet excitons of (S)‐BINAP under strong continuous excitation. The steady–state concentration of the triplet excitons for (S)‐BINAP reached 2.3 × 10−2 M, producing a bright afterglow. Owing to the brighter afterglow, afterglow detection using individual particles with sizes approaching the diffraction limit in aqueous conditions and irradiance‐dependent anticounterfeiting can be achieved.

AbstractA spatial view of macroscopic polymer material properties, in terms of nanostructure and irregularities, can help to better understand engineering processes such as when materials may fail. However, bridging the gap between the molecular‐scale arrangement of polymer chains and the spatially resolved macroscopic properties of a material poses numerous difficulties. Herein, an integrated messenger material that can report on the material micro‐ to nanostructure and its processes is introduced. It is based on polymer chains labeled with fluorescent dyes that feature Förster resonance energy transfer (FRET) dependent on chain conformation and concentration within a host polymer material. These FRET materials are integrated within electrospun polystyrene microfibers, and the FRET is analyzed by confocal laser scanning microscopy (CLSM). Importantly, the use of CLSM allows a spatial view of material nanostructure and irregularities within the microfibers, where changes in FRET are significant when differences in fiber geometries and regularities exist. Furthermore, changes in FRET observed in damaged regions of the fibers indicate changes in polymer conformation and/or concentration as the material changes during compression. The system promises high utility for applications where nano‐to‐macro communication is needed for a better understanding of material processes.

Published: October 2023

AbstractNon‐Hermitian degeneracies, also known as exceptional points (EPs), have attracted considerable attention due to their unique physical properties. In particular, metasurfaces related to EPs can open the way to unprecedented devices with functionalities such as unidirectional transmission and ultra‐sensitive sensing. Herein, an active non‐Hermitian metasurface with a loss‐induced parity‐time symmetry phase transition for ultrafast terahertz metadevices is demonstrated. Specifically, the eigenvalues of the non‐Hermitian transmission matrix undergo a phase transition under optical excitation and are degenerate at EPs in parameter space, which is accompanied by the collapse of chiral transmission. Ultrafast EP modulation on a picosecond time scale can be realized through variations in the transient loss at a non‐Hermitian metasurface pumped by pulsed excitation. Furthermore, by exploiting the physical characteristics of chiral transmission EPs, a switchable quarter‐wave plate based on the photoactive metasurface is designed and experimentally verified and realized the corresponding function of polarization manipulation. This work opens promising possibilities for designing functional terahertz metadevices and fuses EP physics with active metasurfaces.

Published: October 2023

AbstractA series of Sr‐modified hedgehog‐like La2O2CO3 (Sr/LOC‐HL) catalysts were synthesized by the two‐step methods of coordination polymer induced formation and incipient wetness impregnation. Sr/LOC‐HL catalysts show the uniform nanorod morphology with width of 180 nm. The strong interaction between SrOx species and La2O2CO3 boosts the formation of active oxygen species for enhancing CH4 activation at low temperature. Sr/LOC‐HL catalysts show excellent catalytic performances for oxidative coupling of methane into C2+ hydrocarbons at low temperature (<500°C), and the selectivity is strongly dependent on the strong surface basic sites induced by the SrOLa bond. The Sr10/LOC‐HL catalyst exhibits the best catalytic performance and stability for OCM reaction at low temperature, that is, its CH4 conversion, C2+ selectivity, and yield at 450°C is 20.3%, 69.1%, and 13.2%, respectively; and its catalytic activity maintains stable during 3000 min. Insight into role of surface Sr‐sites would further improve catalytic performance at low temperature.

Published: October 2023

AbstractObjectivesPrevious research revealed that in some African populations, food‐production strategies are associated with facial shape. Nomadic pastoralists living in the African Sahel/Savannah belt have a different facial morphology than their sedentary neighbors. We investigated whether the lifestyle associated with a subsistence pattern has an impact on sexual dimorphism in the facial structure.MethodsWe employed several methods from geometric morphometrics and demonstrated such effect in four ethnically distinct populations that share the same geographic space.ResultsWe show that the facial traits which correlate with a subsistence strategy are systematically associated with levels of facial sex‐typicality. In particular, we found that faces with more pronounced pastoralist features have on average more masculine facial traits and that this effect is more pronounced in men than in women.ConclusionsIn general, though, the magnitude of overall facial dimorphism does not differ between pastoralists and farmers. Pastoralists (in contrast to farmers) tend to have a more masculine facial morphology but facial differences between the sexes are in both groups the same.

AbstractINTRODUCTIONFew studies have examined the associations of psychosocial factors with cognitive change in Hispanics/Latinos.METHODSData from the Hispanic Community Health Study/Study of Latinos‐Investigation of Neurocognitive Aging (HCHS/SOL INCA) and Sociocultural studies were used (n = 2,155; ages ≥45 years). Psychosocial exposures included intrapersonal (ethnic identity, optimism, purpose in life), interpersonal (family cohesion, familism, social networks, social support), and social factors (ethnic discrimination, loneliness, subjective social status). Survey‐linear regression models examined associations between psychosocial exposures and 7‐year cognitive change (global cognition [GC], verbal learning, memory, word fluency [WF], and digit symbol substitution [DSS]).RESULTSFamilism predicted decline in GC, verbal learning, and memory; family cohesion predicted DSS decline; and loneliness predicted memory decline. Ethnic identity was protective against decline in GC and memory, optimism and social support were protective against decline in memory, and purpose in life was protective against WF decline.DISCUSSIONPsychosocial factors are differentially related to cognitive changes. Culturally relevant factors should be explored in Hispanic/Latino cognitive aging research.Highlights

AbstractWe found that our optically CO2‐responsive polydimethylsiloxane (PDMS) elastomer rapidly and reversibly underwent both visible and fluorescent color changes in the presence of CO2 gas. Unlike conventional optically CO2‐responsive polymeric materials, it functions in totally dry gaseous conditions. The visible color and fluorescence of the elastomer sheet change after only 1 min of exposure to CO2, and the sheet exhibits excellent repeatability in terms of color switching that persists for at least 20 times.

AbstractGlycosylation is a ubiquitous posttranslational modification and plays an important role in many processes, such as protein stability, folding, processing, and trafficking. Among glycosylation types, O‐glycosylation is difficult to analyze due to the complex glycan composition, low abundance and lack of glycosidases to remove the O‐glycans. Many methods have been applied to analyze the O‐glycosylation of membrane glycoproteins and secreted glycoproteins since the synthesis of O‐glycosylation occurred in the Golgi apparatus. In recent years, some O‐glycosylation has been reported in the nucleus. In this work, we present a proximity labeling strategy based on TurboID by combining core 1 β1‐3 galactosyltransferase (C1GalT1), which has been reported in the nucleus, to characterize nucleocytoplasmic O‐glycosylation in living HeLa cells. The O‐glycosylated protein C1GalT1 was biotinylated by the proximity labeling method in living HeLa cells overexpressing C1GalT1 fused by TurboID and enriched by streptavidin‐coated beads. Following digestion with trypsin and mass spectrometry analysis, 68 high‐confidence and 298 putative O‐glycosylated sites were identified on 366 peptides mapped to 267 proteins. These results indicated that the proximity labeling method is a highly efficient technique to identify O‐glycosylation. Furthermore, the finding of abundant O‐glycosylation from nucleocytoplasmic proteins indicates a new pathway of O‐glycosylation synthesis in cells.

AbstractCO2 hydrogenation utilizing sustainably produced hydrogen and CO2 derived from industrial exhaust gas represents a pivotal technology for chemical energy storage and climate change mitigation. This work aims to identify the best combination of catalyst support, synthesis method and promotor for In2O3/ZrO2 catalysts in a typical fixed‐bed configuration. Intense characterization using ICP‐OES, XRD, XPS, N2‐physisorption, CO2‐TPD, H2‐TPR and SEM‐EDX provide molecular insights into the different effects caused by various synthesis methods and doping elements. Doping the most promising In2O3/ZrO2 (M‐SG) catalyst with 0.7 wt. % NiO by wetness impregnation using an ethanol/water mixture as a solvent, an increased methanol production rate of 0.497 gMeOH ⋅
⋅ h−1 could already be achieved at 250 °C. Hereby, the low amount of highly dispersed NiO promotes H2 activation via hydrogen spillover, leading to sustained catalytic activity for 100 hours of time‐on‐stream.

Published: October 2023

AbstractComminuted fractures are orthopedic traumas with greater surgical difficulty. In clinical treatment, a great challenge is precise reduction of multiple broken bone fragments; Another great challenge is personalized and precise internal fixation after reduction. For these two issues, we designed an automated method framework for precise reduction and internal fixation of comminuted fractures. First, the Gaussian mixture model (GMM) is used to distinguish section points and noise points in a broken bone model; Second, ellipse fitting is carried out to achieve section points matching and a descriptor is proposed to describe the section features; Then, the Convolution Auto‐Encoder (CAE) and genetic algorithm are used to extract feature vectors; Finally, after broken bone models registration, internal fixed plate can be reconstructed. Three verification experiments for comminuted bone fracture show this method has high accuracy and good efficiency. It can provide support for minimally invasive treatment for comminuted fractures.

AbstractDeveloping renewable means of activating molecules over traditional catalysts for C−C bond formation is desirable for industrial applications. Herein, we report a strategy to improve the efficiency of Pd nanoparticles (NPs) for the Suzuki cross‐coupling reactions by visible‐light irradiation using g‐C3N4 nanosheets (NSs) as photosensitizer. Pd NPs mounted on g‐C3N4 become electron‐rich under visible‐light due to generation of excited electrons in g‐C3N4 and thereby accelerate the rate‐determining step. Remarkable photocatalytic activity was accomplished utilizing Pd/g‐C3N4 for the Suzuki cross‐coupling reaction in environmentally benign aqueous settings under room temperature conditions. The activity remarkably improves (~2.5 times) upon light irradiation, yielding one of the highest known turnover frequencies (TOF) of 1858 h−1 and confirming the photosensitizer role of g‐C3N4. The TOF for coupling of aryl bromides is also significantly high (~356 h−1). We establish that the low‐energy/long‐lived excitons preferencially transfer to Pd, paving a way for rational designing photocatalysts for various C−C coupling reactions.
Cognitive factors underlying the impact of postmigration stressors on subjective well‐being: Well‐being comparisons and self‐efficacy

Published: October 2023

AbstractBackgroundMigration and the resulting challenges in the host country can have a profound impact on the mental health of refugees and intensify preoccupation with one's own well‐being. Yet, cognitive factors underlying the adverse impact of postmigration stressors are poorly understood.ObjectiveWe aimed at exploring the frequency and nature of well‐being comparisons in the context of flight and migration using the Comparison Standards Scale for Well‐being (CSS‐W), which assesses well‐being related social, temporal, counterfactual, criteria‐based and dimensional aversive and appetitive comparisons. We further aimed at examining the mediating role of well‐being comparisons and general self‐efficacy in the relationship between postmigration stressors and psychological well‐being.MethodsWe conducted a survey with 1070 Arabic speaking forcibly displaced people in Germany assessing well‐being comparisons, general self‐efficacy, postmigration stressors, subjective well‐being and social media engagement.ResultsFactor analysis of the CSS‐W yielded a theoretically grounded two‐factor structure proposing an aversive (mostly upward) and an appetitive (mostly downward) comparison factor. Aversive and appetitive comparisons were reported by more than 99% of participants, with temporal comparisons being reported by 98.7% of participants. Postmigration stressors were significantly related to subjective well‐being and aversive well‐being comparisons and general self‐efficacy partially mediated this relationship. Appetitive well‐being comparisons, however, were not significantly related to neither postmigration stressors nor general self‐efficacy.ConclusionAversive well‐being comparisons and general self‐efficacy seem to play a significant role in the adverse effects of postmigration stressors on subjective well‐being. Longitudinal research is needed to examine the directional dynamics between general self‐efficacy, well‐being comparisons and postmigration stressors.
Design and analysis of compact dual‐band WPT system using capacitively loaded interdigital capacitor
Authors: Atallah Hany A. 
Published: October 2023

SummaryIn this paper, a noteworthy compact dual‐band wireless power transfer (DB‐WPT) system is presented and studied. This DB‐WPT system is proposed using a capacitively loaded interdigital capacitor which reduces the size of the whole system, lessens the number of the attached surface mount elements, and accomplishes high efficiencies. An interdigital capacitor is printed in the ground plane of the design and loaded with a chip capacitor to produce dual bands. The operation of the system is verified by fabricating the proposed DB‐WPT system, which shows measured coupling efficiencies of 96% and 98.8% at 0.53 and 1.1 GHz, respectively at a transfer space of 12 mm. The fabricated structure has dimensions of 13.5 mm × 20 mm. The results show good agreement between the circuit model and the measurements. The idea of this design makes it applicable for compact near‐field WPT applications.
