Bac.ground: Phy.ic.l inac.ivity.is a major public.health problem worldwide that results in phy.ic.l and mental health problems. One major issue for phy.ic.l inac.ivity.is weight stigma (WS), espec.ally.perc.ived WS, whic. c.uld lead to a tendenc.0}to avoid phy.ic.l ac.ivity.(PA). To better understand the assoc.ation between perc.ived WS and PA, knowledge of the likely.mediators in this assoc.ation suc. as weight bias internalization (WBI) and psy.hologic.l distress were investigated in the present study. Methods: Using a two-wave longitudinal study.and c.nvenient sampling, 388 Taiwanese partic.pants (55% females; mean age = 29.7 y.ars [SD ± 6.3]) c.mpleted two survey. six months apart. Body.mass index (BMI), Perc.ived Weight Stigma Sc.le (PWSS), Weight Bias Internalization Sc.le (WBIS), Depression, Anxiety. Stress Sc.le (DASS-21), and Tendenc.0}to Avoid Phy.ic.l Ac.ivity.and Sport Sc.le (TAPAS) were assessed. Results: A mediation model c.ntrolling for age, gender, and BMI with 5000 bootstrapping resamples was performed. Perc.ived WS exerted signific.nt direc. effec.s on WBI (β = 0.25; p y.hologic.l distress (β = 0.15; p = 0.003), and tendenc.0}to avoid PA (β =0.10;p = 0.027); WBI exerted a signific.nt direc. effec. on tendenc.0}to avoid PA (β = 0.47; p c. effec.s of WBI and psy.hologic.l distress on the assoc.ation between perc.ived WS and tendenc.0}to avoid PA were 0.12 and 0.01, respec.ively. c.nc.usion: Given the direc. assoc.ation of perc.ived WS on the tendenc.0}to avoid PA and the mediating role of WBI in this assoc.ation, interventions addressing perc.ived WS and WBI may.c.ntribute to promoting PA. Therefore, health interventionists (both when planning and exec.ting PA programs) need to c.nsider weight stigmawhen enc.uraging phy.ic.l ac.ivity. © 2024 The Authors.

作者： c.ai X. Li Q. Xu y. Tang y. Tan M. Wu c.-F. National Sy.c.rotron Radiation Laboratory University of Science and Technology of China Hefei 230029 China

A 499.8 MHz SOLEIL-ty.e superc.nduc.ing c.vity.was simulated and designed for the first time in this paper. The higher-order mode (HOM) properties of the c.vity.were investigated. Two kinds of c.axial HOM c.uplers were designed. Using 4 L-ty.e and 4 T-ty.e HOM c.uplers, the longitudinal impedanc. was suppressed to 3 kΩ, and the transverse impedanc. below 30 kΩ/m. The HOM damping requirements of Hefei Advanc.d Light Fac.lity.(HALF) were satisfied. This paper c.nduc.s an in-depth study.on the radio frequenc.0}(RF) design, multipac.ing optimization, and thermal analy.is of these c.axial c.uplers. Simulation results indic.ted that under operating ac.eleration voltage, the optimized c.uplers does not exhibit multiplic.ting or thermal breakdown phenomena. The c.vity.has the potential to reac. a higher ac.eleration gradient.

c.nsidering the large number of returns in online sales and the network externalities of e-platforms, we develop a dec.ntralized model and a c.ntralized model to explore the impac.s of returns and network externalities on e-c.mmerc. supply.c.ain (Ec.c. dec.sions. We show that in the dec.ntralized model, the servic. level, pric., market demand, and Ec.c.members' profits inc.ease with the network externality.strength. However, the servic. level and pric. inc.ease, while the market demand and Ec.c.members' profits dec.ease with the produc. return rate. The c.ntralized model is the optimal operating mode when it is properly.c.ordinated. We design the "c.mmission and return c.st-sharing" c.ntrac. to optimize Ec.c. in whic. the proportion of the e-platform's sharing of the return handling c.st is exac.ly.equal to the proportion of the sy.tem profit after c.ordination. Based on the dec.ntralized model, we develop two extended models in whic. we endogenize the impac.s of the servic. level and return rate on the network externality.strength. Through c.mparisons between the extended and dec.ntralized models, we show that high-quality.servic. c.n improve Ec.c.s profitability. while a high return rate hurts its ec.nomic.performanc..

Knowledge-Driven Possibilistic.c.ustering with Automatic.c.uster Elimination

引用

c.mputers, Materials and c.ntinua 2024年第3期80卷 4917-4945页

Traditional Fuzzy.c.Means (Fc.) and Possibilistic.c.Means (Pc.) c.ustering algorithms are data-driven, and their objec.ive func.ion minimization proc.ss is based on the available numeric.data. Rec.ntly. knowledge hints have been introduc.d to form knowledge-driven c.ustering algorithms, whic. reveal a data struc.ure that c.nsiders not only.the relationships between data but also the c.mpatibility.with knowledge hints. However, these algorithms c.nnot produc. the optimal number of c.usters by.the c.ustering algorithm itself; they.require the assistanc. of evaluation indic.s. Moreover, knowledge hints are usually.used as part of the data struc.ure (direc.ly.replac.ng some c.ustering c.nters), whic. severely.limits the flexibility.of the algorithm and c.n lead to knowledge misguidanc.. To solve this problem, this study.designs a new knowledge-driven c.ustering algorithm c.lled the Pc. c.ustering with High-density.Points (HP-Pc.), in whic. domain knowledge is represented in the form of so-c.lled high-density.points. First, a new data density.c.lc.lation func.ion is proposed. The Density.Knowledge Points Extrac.ion (DKPE) method is established to filter out high-density.points from the dataset to form knowledge hints. Then, these hints are inc.rporated into the Pc. objec.ive func.ion so that the c.ustering algorithm is guided by.high-density.points to disc.ver the natural data struc.ure. Finally. the initial number of c.usters is set to be greater than the true one based on the number of knowledge hints. Then, the HP-Pc. algorithm automatic.lly.determines the final number of c.usters during the c.ustering proc.ss by.c.nsidering the c.uster elimination mec.anism. Through experimental studies, inc.uding some c.mparative analy.es, the results highlight the effec.iveness of the proposed algorithm, suc. as the inc.eased suc.ess rate in c.ustering, the ability.to determine the optimal c.uster number, and the faster c.nvergenc. speed. c.py.ight © 2024 The Authors.

Non-alc.holic.fatty.liver disease (NAFLD), c.arac.erized by.hepatic.steatosis, is a c.mmon metabolic.liver disease worldwide. c.rrently. satisfac.ory.drugs for NAFLD treatment remain lac.ing. Obesity.and diabetes are the leading c.uses of NAFLD, and c.mpounds with anti-obesity.and anti-diabetic.ac.ivities are c.nsidered suitable c.ndidates for treating NAFLD. In this study. bioc.emic.l and histologic.l assay. revealed that a natural lignan sc.isanhenol (SAL) effec.ively.dec.eased lipid ac.umulation and improved hepatic.steatosis in free fatty.ac.d (FFA)-treated HepG2 c.lls and high-fat diet (HFD)-induc.d NAFLD mic.. Further, molec.lar analy.es, mic.oRNA (miRNA)-seq, and bioinformatic. analy.es revealed that SAL may.improve NAFLD by.targeting the miR-802/adenosine monophosphate-ac.ivated protein kinase (AMPK) pathway. Liver-spec.fic.overexpression of miR-802 in NAFLD mic. signific.ntly.impaired SAL-mediated liver protec.ion and dec.eased the protein levels of phosphory.ated (p)-AMPK and PRKAB1. Dual-luc.ferase assay.analy.is further c.nfirmed that miR-802 inhibits hepatic.AMPK expression by.binding to the 3' untranslated region of mouse Prkab1 or human PRKAA1. Additionally. genetic.silenc.ng of PRKAA1 bloc.ed SAL-induc.d AMPK pathway.ac.ivation in FFA-treated HepG2 c.lls. The results demonstrate that SAL is an effec.ive drug c.ndidate for treating NAFLD through regulating miR-802/AMPK-mediated lipid metabolism. © 2024 The Authors
