Zusammenfassung
Hintergrund Eine etablierte Möglichkeit zur simultanen
Rekonstruktion von Knochen- und Weichteildefekten stellt der frei
vaskularisierte osteokutane Beckenkammspanlappen mit Hautinsel dar, der durch
die Arteria und Vena circumflexa ilium profunda genährt wird. Die
Ausprägung dieser kutanen Perforatoren ist jedoch nicht konstant. Ein
alternative Rekonstruktionstechnik bei fehlenden Hautperforatoren stellt die
Verwendung der sequenziell chimären Lappenplastik dar mit dem Ramus
ascendens als ausschlaggebendem Anschlussgefäß.
Patient und Methode Ein 58-jähriger Mann zog sich bei einem
Lawinenverschüttungstrauma eine offene Tibiafraktur mit ausgedehntem
Weichteil- und Knochendefekt zu. Wir rekonstruierten diesen osteokutanen Defekt
mittels sequenziellem chimären Beckenkamm-SIEA-Lappen.
Ergebnisse Die Schonung des Ramus ascendens der Arteria und Vena
circumflexa ilium profunda ermöglichte uns die Durchführung
eines sequenziell chimären Beckenkamm-SIEA-Lappens.Dieser osteokutane
sequenzielle chimäre Beckenkamm-SIEA-Lappen heilte komplikationslos ein.
Bei unserem Patienten entwickelte sich im Bereich der Entnahmestelle eine
Hernie, die nach chirurgischer Behandlung ohne weitere Auffälligkeiten
abheilte. Der Patient erlangte eine zufriedenstellende Funktion des linken
Unterschenkels und kann erneut alltäglichen und sportlichen
Tätigkeiten nachgehen.
Schlussfolgerung Auf die Schonung des Ramus ascendens sowie die
Gefäße zur Hebung entweder eines konsekutiven SIEA- oder
SCIP-Lappens ist bei der Präparation des osteokutanen
Beckenkammtransplantates zu achten.

Abstract
Objective Sleep restfulness is closely associated with mortality. Thus, it is an important sleep-related symptom in the general population. However, it is rarely evaluated in patients with obstructive sleep apnea (OSA) syndrome. The present study examined the importance of sleep restfulness in patients with OSA receiving continuous positive airway pressure (CPAP) therapy.
Materials and Methods We administered sleep-related questionnaires, which included items such as subjective sleep duration and sleep restfulness, to 775 patients with OSA receiving CPAP therapy. Sleep restfulness was rated using a 5-point Likert-type scale, with the score of 5 indicating restfulness. Good adherence to CPAP therapy was defined as the use of CPAP therapy for at least 4 h per night in 70% of nights.
Results We excluded 105 patients with lacking data. Thus, 670 patients were finally examined. In total, 29 (4.3%), 124 (18.5%), 139 (20.8%), 235 (35.1%), and 143 (14.3%) patients answered restless (1), somewhat restless (2), neither (3), somewhat restful (4), and restful (5) respectively. A total of 467 (69.7%) patients had good adherence to CPAP therapy. Multivariate logistic regression analysis showed that sleep restfulness was independently and positively associated with subjective sleep duration (≥ 7 hours) and good adherence to CPAP therapy.
Conclusion Sleep restfulness was associated with subjective sleep duration and good adherence to CPAP therapy in patients with OSA. Favorable outcomes are significantly correlated with good adherence to CPAP therapy. Thus, sleep restfulness can be an indicator of a subtype that has favorable outcomes in patients after CPAP therapy.

Published: February 2024

AbstractPilates is a holistic exercise focused on respiration, body control, and accuracy of movements, and it improves respiratory muscle strength, balance, quality of life, and overall physical performance. However, little is known about the effect of Pilates on sleep quality. The purpose of the present prospective observational study was to evaluate the effect of four months of Pilates training on the quality of sleep, aerobic capacity, and anaerobic power in premenopausal women. The sample consisted of 53 premenopausal women: one experimental group (n = 40) and one control group (n = 13). Participants in the experimental group received at least three one-hour sessions of Pilates exercise per week for 16 weeks. The two groups were similar at baseline. After 4 months of Pilates, the intervention group had significantly lower scores on the Athens Insomnia Scale, Epworth Sleepiness Scale, and autonomic arousal index compared to the baseline scores. The intervention group presented significant improvement in aerobic fitness, muscle strength, flexibility, balance, abdominal muscle endurance, as well as in the general health and social functioning subscales of the 36-Item Short Form Health Survey (SF-36). Pilates workouts appeared to improve sleep quality in premenopausal women, as well as the basic parameters of fitness and quality of life.

Published: February 2024

Abstract
Introduction About 65% of adult Americans report playing video games. Despite potential impacts to functioning, there is limited research on the relationship between video game use and sleep, specifically among adults. The present study expands upon the literature by describing demographic, video game, and sleep characteristics of an international adult sample of gamers.
Methods The participants were 3,481 adults aged 18 to 74 who responded to an online questionnaire about video game use (i.e., quantity of play, most common game type), general sleep characteristics (i.e., sleep onset latency [SOL]; duration, sleep timing, and sleep quality), and gaming-specific sleep disruptors (i.e., game-related night awakenings and sleep delays). Most identified as cisgender male (79.8%) and white (77%).
Results Participants reported an average SOL of 24.63 minutes, and most (64.5%) had a sleep duration from 7 to 9 hours with an overall average of 8.42 hours. Most (58.7%) reported that their sleep quality was fair to very poor. Bed and wake times were generally delayed, with 51% reporting a late evening or early morning bedtime and an average wake time of 8:28 am. A majority (81.2%) indicated that their bedtime was delayed due to game-related activities, but game-related night awakenings were less common.
Conclusion Although many report a sufficient amount of sleep, adult gamers tend to report sleep disruptions in other domains, particularly regarding a delayed sleep schedule and poor sleep quality. This may be attributable to game-related bedtime delays or other game-specific factors (e.g., game type) that should be evaluated in the future.

Published: February 2024

Abstract
Background Given the inequities in access to health care resources like COVID-19 vaccination, health systems should carefully consider how to reach underrepresented groups. Reflecting on vaccine rollout efforts holds insight on the role of community engagement and informatics support in promoting health equity.
Objectives This study aimed to assess the effectiveness of four outreach strategies deployed by University of Washington (UW) Medicine in improving vaccine equity over traditional vaccine scheduling online or by phone, we report on appointment scheduling and completion of appointments (i.e., vaccine administration) through (1) automated outreach to individuals from underrepresented groups, (2) temporary “pop-up” clinics in neighborhoods highly impacted by COVID-19, (3) vulnerable population clinics, and (4) mobile vaccine vans.
Methods We conducted a 6-month retrospective analysis of electronic health records (EHR) to describe the sociodemographic characteristics of individuals who scheduled appointments using the outreach strategies and characteristics associated with a greater likelihood of vaccine administration based on appointment completion. To help explain trends in the EHR data, we engaged 10 health system leaders and staff who spearheaded the outreach strategies in follow-up conversations to identify qualitative insights into what worked and why.
Results Compared with traditional scheduling, all outreach strategies except vulnerable population clinics had higher vaccine appointment completion rates, including automated outreach (N = 3,734 [94.7%], p < 0.001), pop-up clinics (N = 4,391 [96.0%], p < 0.001), and mobile vans (N = 4,198 [99.1%], p < 0.001); and lower cancellation rates, including automated outreach (N = 166 [1.1%], p < 0.001), pop-up clinics (N = 155 [0.6%], p < 0.001), and mobile vans (N = 0 [0%], p < 0.001). Qualitative insights emphasized ongoing community partnerships and information resources in successful outreach.
Conclusion Vaccine equity outreach strategies improved the proportion of patients who scheduled and completed vaccination appointments among populations disproportionately impacted by COVID-19. Engaging community partners and equity-focused informatics tools can facilitate outreach. Lessons from these outreach strategies carry practical implications for health systems to amplify their health equity efforts.
Reconciling China’s maritime discourses of nationalism and international engagement with left Confucian logic
Authors: Wang Weijin 
Published: February 2024

AbstractChina’s discursive combination of nationalism and international engagement with its maritime neighbours seems self-defeating. To explain why this narrative strategy has been deemed apt, previous studies have predominantly followed a realist approach and contended that China’s international engagement is pure statecraft to help its national rejuvenation efforts. As the merits of Confucianism increasingly affect contemporary Chinese socialism, this paper interprets the internarrativity of left Confucian ethics, Chinese nationalism and international engagement in East China Sea geopolitics. It argues that China tends to identify itself as a contributor to common material interest in the international community. With the notion of graded love, the contribution to the people of the world does not undermine the self-interests. China’s national defence is often allegedly conducted alongside the defence of the existing order enabling its contribution. China does not aim to challenge the order per se, but it challenges the US and its allies’ collective interpretations of it. This situation leads to antagonistic peace when the US-led alliance is unstable. However, if the US’s geopolitical alliance is strong enough to withstand the solipsistic interpretation of the order, the Chinese dream of national rejuvenation can be better realized.
Bidirectional reduction effects of perceived stress and general self-efficacy among college students: a cross-lagged study
Authors: Liu Xinqiao , Li Yan , Cao Xiaojie 
Published: February 2024

AbstractPerceived stress and general self-efficacy are important issues closely related to the mental health and academic performance of college students. Previous studies have explored the correlation between perceived stress and general self-efficacy, but the understanding of the reciprocal effects of these two factors is still limited. Based on two-wave longitudinal data, this study investigated the bidirectional relationship between perceived stress and general self-efficacy in a sample of Chinese college students. The correlation results showed that perceived stress was significantly negatively correlated with general self-efficacy. Furthermore, by cross-lagged analysis, it was found that perceived stress can significantly negatively predict subsequent general self-efficacy and that general self-efficacy can significantly negatively predict subsequent perceived stress. Bidirectional reduction effects between perceived stress and general self-efficacy are observed among Chinese college students. The results emphasize the necessity of timely stress intervention for college students and the establishment of measures to enhance general self-efficacy.
Effect of Ta buffer layer on the structural and magnetic properties of stoichiometric intermetallic FeAl alloy
Authors: Bhardwaj Sunayana , Kumar Prashant , Ghosh Ram Krishna , Kuanr Bijoy K. 
Published: February 2024

The magnetostructural phase transition in Fe50Al50 alloy with chemically ordered paramagnetic B2 and disordered ferromagnetic (FM) A2 phase has applications in spintronics such as phase-change magnetic memory and magnonic devices. We first conducted a systematic first-principles density functional theory study of the A2 and B2 phases in the Fe50Al50 alloy. A theoretical understanding of this equiatomic alloy’s electronic and spin-dynamical properties leads us to the experimental exploration of the FM A2 phase. Therefore, we deposit the 50 nm Fe50Al50 alloy thin film using sputtering and investigate the influence of the Ta buffer layer on its structural and magnetic properties. Our results reveal that the film with a buffer layer exhibits the A2 phase with appreciably higher saturation magnetization (848 emu/cc) than the film without a buffer layer (576 emu/cc). However, the surface roughness and Gilbert damping (α) slightly increase with the presence of the buffer layer from 0.41 to 0.56 nm and 4.35 × 10−3–4.94 × 10−3, respectively. The enhancement in α is due to extrinsic contributions induced by surface inhomogeneities.
Nested solutions of gravitational condensate stars
Authors: Jampolski Daniel , Rezzolla Luciano 
Published: February 2024

Abstract
Black holes are normally and naturally associated to the end-point of gravitational collapse. Yet, alternatives have been proposed and a particularly interesting one is that of gravitational condensate stars, or gravastars. We here revisit the gravastar model and increase the degree of speculation by considering new solutions that are inspired by the original model of gravastars with anisotropic pressure, but also offer surprising new features. In particular, we show that it is possible to nest two gravastars into each other and obtain a new solution of the Einstein equations. Since each gravastar essentially behaves as a distinct self-gravitating equilibrium, a large and rich space of parameters exists for the construction of nested gravastars. In addition, we show that these nested-gravastar solutions can be extended to an arbitrarily large number of shells, with a prescription specified in terms of simple recursive relations. Although these ultra-compact objects are admittedly very exotic, some of the solutions found, provide an interesting alternative to a black hole by having a singularity-free origin, a full matter interior, a time-like matter surface, and a compactness

Universal synchronization: acoustic experiments, the phase oscillator model and mechanical analogues
Authors: Euler Manfred 
Published: February 2024

Abstract
Although synchronization effects play an important role in many areas of basic and applied science, their treatment in undergraduate physics courses requires more attention. Based on acoustic experiments with a driven organ pipe, the article proposes analytical, numerical and qualitative approaches to this universal phenomenon, suitable for introductory teaching. The Adler equation is developed, a first-order nonlinear differential equation describing the phase dynamics of driven self-sustained oscillations in the weak coupling limit. Analytical solutions, intuitive mechanical analogues and properties of the resulting comb spectra are discussed. The underlying phase model is paradigmatic for synchronization-based self-organization phenomena in a wide range of fields, from physics and engineering to life and social sciences.
Indispensability of cross-shell contributions in neutron resonance spacing
Authors: Ghosh T , Sangeeta  , Maheshwari B , Saxena G , Agrawal B K 
Published: February 2024

Abstract
Spin- and parity-dependent nuclear level densities (NLDs) are obtained for a configuration interaction shell model using a numerically efficient spectral distribution method. The calculations are performed for 24Na and 25,26,27Mg nuclei using full sd-pf model space that incorporates the cross-shell excitations from the sd to the pf-shell. The obtained NLDs are then employed to determine the s-wave neutron resonance spacing (D0), which is one of the crucial inputs for the predictions of astrophysical reaction rates. Although the considered nuclei are not neutron-rich, the contributions from cross-shell excitations to the pf-shell are indispensable for explaining the experimental data for D0, which otherwise are significantly overestimated.
Complex patterning in jerky flow from time series analysis and numerical simulation
Authors: Fressengeas Claude , Lebedkina Tatiana A , Lebyodkin Mikhail A 
Published: February 2024

Abstract
The paper is a tribute to Ladislas P Kubin’s long-standing work on the collective behavior of dislocations in jerky flow. In a first part, it reviews his contributions to the statistical, dynamical and multifractal analyses carried out on stress-time series recorded from both single crystals and polycrystalline samples of dilute alloys subjected to tensile tests at constant strain rate. Various spatio-temporal dynamical regimes were found as the applied strain rate was varied. Type C static bands were associated with quasi-random collective behavior, the hopping type B and propagating type A bands could be shown to correspond to chaotic and self-organized critical dynamics, respectively. The crossover between the A and B regimes was characterized by a large spread in the multifractal spectrum of stress drops, associated with heterogeneity of the dynamics. In a second part, the paper reviews the nonlocal models Ladislas inspired to interpret these results from numerical solutions of the boundary value problem, on the basis of dynamic strain aging, the incompatibility stresses associated with dislocations, their plastic relaxation and the spatial couplings they inherently involve. Eventual developments of this research, rooted in the same ideas, on the statistical and multifractal analyses of the accompanying acoustic emission are reviewed and discussed in terms of the synchronization of small-scale plastic events.

A better integration of health and economic impact assessments of climate change
Authors: Orlov Anton , Schleypen Jessie , Aunan Kristin , Sillmann Jana , Gasparrini Antonio , Mistry Malcolm N 
Published: February 2024

Abstract
Climate change could lead to high economic burden for individuals (i.e. low income and high prices). While economic conditions are important determinants of climate change vulnerability, environmental epidemiological studies focus primarily on the direct impact of temperature on morbidity and mortality without accounting for climate-induced impacts on the economy. More integrated approaches are needed to provide comprehensive assessments of climate-induced direct and indirect impacts on health. This paper provides some perspectives on how epidemiological and economic impact assessments could be better integrated. We argue that accounting for the economic repercussions of climate change on people’s health and, vice versa, the consequences of health effects on the economy could provide more realistic scenario projections and could be more useful for adaptation policy.

Published: February 2024

Abstract
Drought-induced productivity reductions and tree mortality have been increasing in recent decades in forests around the globe. Developing adaptation strategies hinges on an adequate understanding of the mechanisms governing the drought vulnerability of forest stands. Prescribed reduction in stand density has been used as a management tool to reduce water stress and wildfire risk, but the processes that modulate fine-scale variations in plant water supply and water demand are largely missing in ecosystem models. We used an ecohydrological model that couples plant hydraulics with groundwater hydrology to examine how within-stand variations in tree spatial arrangements and topography might mitigate forest vulnerability to drought at individual-tree and stand scales. Our results demonstrated thinning generally ameliorated plant hydraulic stress and improved carbon and water fluxes of the remaining trees, although the effectiveness varied by climate and topography. Variable thinning that adjusted thinning intensity based on topography-mediated water availability achieved higher stand productivity and lower mortality risk, compared to evenly-spaced thinning at comparable intensities. The results from numerical experiments provided mechanistic evidence that topography mediates the effectiveness of thinning and highlighted the need for an explicit consideration of within-stand heterogeneity in trees and abiotic environments when designing forest thinning to mitigate drought impacts.
Developmental status of duku stem-canker in Jambi
Authors: Handoko S , Meilin A , Sulistiono W , Fefirenta A D 
Published: February 2024

Abstract
Dead molt disease or duku stem-canker disease has been widely discussed in several studies. Some suspect it is caused by Phytophthora palmivora, or Ceratocystis fimbriata, and possibly Botryodiplodia spp. In the last decade, studies and discussions in control efforts have been carried out. Control studies using biological control strategies continue to be carried out, especially in the South Sumatera region, as well as control studies using pesticides have also received a lot of attention, but the control results have not reached a satisfactory stage. There are still many duku plants that have experienced widespread mortality. Finally, we will discuss about the research that has done into developing effective and sustainable control strategies.
