This study aims to examine key attributes affecting Airbnb users' satisfaction and dissatisfaction through the analysis of online reviews. A corpus that comprises 59,766 reviews form 27,980 listings located in 12 different cities is analyzed by using both Latent Dirichlet Allocation (LDA) supervised LDA (sLDA) approach. Unlike previous based studies, this examines positive negative separately, results reveal heterogeneity accommodation. In particular, emergence topic “guest conflicts” leads...
As an advanced surface-strengthening technology, laser shock peening (LSP) is suitable for strengthening high-energy beam additive manufacturing components by improving the uneven temperature distribution and mechanical anisotropy problems. The present study investigated influence of multiple LSP impacts on microstructure evolution wear performance wire-based directed energy deposition (LDED) 17-4PH stainless steel. Results showed that with increase impacts, average grain size LDED layer...
The event-based Vision-Language Model (VLM) recently has made good progress for practical vision tasks. However, most of these works just utilize CLIP focusing on traditional perception tasks, which obstruct model understanding explicitly the sufficient semantics and context from event streams. To address deficiency, we propose EventVL, first generative MLLM (Multimodal Large Language Model) framework explicit semantic understanding. Specifically, to bridge data gap connecting different...
Liquid metal embrittlement is a phenomenon in which the mechanical properties of metallic material are significantly reduced after contact with liquid metal, and microscopic mechanism this still controversial. The grain boundary penetration has recently been widely recognized, but theory deficient. To refine penetration, paper, aluminum by gallium obtained situ EBSD, combining it fracture morphology features comparing differences feature changes crack evolution process during tensile...
Abstract With the wide application of liquid metals in various fields, metal embrittlement(LME) has been gradually recognized and emphasized by researchers. The grain boundary penetration mechanism is considered to be most reasonable explanation for LME at present, but there a lack evidence prove that decrease cohesion due main factor embrittlement. In order refine mechanism, this paper performs Ga-Al systems different temperatures observes micro-morphology pure aluminum specimens with...
Endoreplication is characterized by multiple rounds of DNA replication without cell division and determines the growth final size endoreplicating cells tissues in eukaryotes. The cyclic ubiquitination degradation several cycle regulators are required for endoreplication progression. However, deubiquitinase that deubiquitinates stabilizes key factors to modulate remains unknown. Here, we found Drosophila salivary gland Bombyx silk depletion ubiquitin-specific peptidase 8 (USP8) led arrest a...
In this study, we focused on the effect of underwater explosion parameters multi-point array explosion. The shock wave and bubble aggregate charge, two charges, four charges were measured through an test, their influence power field charge quantity distance was analyzed. Results show that multi-shock collision can be approximated to a linear superposition, interaction delayed deemed as increase baseline. Shock focusing superposition peak pressure. Compared with greater number points is,...
A novel polymethacrylimide foam-filled square carbon fiber reinforced composite honeycomb core was proposed and prepared. Numerical simulations theoretical predictions were conducted to study the quasi-static compressive strength of hybrid core. The effects material structural parameters on analyzed. results show that failure modes under compression include elastic buckling plastic fracture failure. change law with increase in relative density can be divided into three phases, including...
Abstract. We study properties of nonlinear magnetic fluctuations in the turbulent boundary layer (TBL) over polar cusps during a typical TBL crossing on 19 June 1998. Interball-1data summer are compared with that Geotail solar wind (SW) and Polar northern TBL. In two characteristic slopes seen: ~ - 1 at (0.004- 0.08) Hz 2.2 (0.08-2) Hz. present evidences random current sheets features coherent solitons can result in: (i) power spectra; (ii) demagnetization SW plasma "diamagnetic bubbles";...
High‐latitude observations of plasma flow across the magnetopause are made by Interball‐Tail satellite near polar cusp for steady southward and dawnward interplanetary magnetic field. Three‐dimensional proton distribution functions measured in this region contain features predicted existing reconnection models. D‐shaped distributions magnetospheric parts field lines with cutoff zero velocity parallel to tablet‐shaped tailward from observed can be interpreted terms a gradually diminishing ion...
It is assumed that the drift parameter dependent on acceleration variables and diffusion coefficient remains same across whole accelerated degradation test (ADT) in most of literature based Wiener process. However, variation would also become obvious some applications with stress increasing. Aiming at phenomenon, paper concludes both depend invariance principle failure mechanism Nelson assumption. Accordingly, constant process (CSADP) step (SSADP) random effects are modeled. The unknown...
A non-overlapping domain decomposition method is developed for coupled Stokes-Darcy flows in irregular domains. The Stokes region discretized by standard finite elements while the Darcy multipoint flux mixed element method. subdomain grids may not match on interfaces and mortar are employed to impose weakly interface continuity conditions. can be curved matching conditions imposed via appropriate mappings from physical reference with flat interfaces. global problem reduced a problem, which...
This study is a multiscale experimental investigation into the embrittlement of Al-Zn-Mg aluminum alloy (7075-T6) caused by liquid metal gallium. The results experiment demonstrate that tensile strength 7075-T6 significantly weakens with an increase in temperature and prolonged time, whereas it improves strain rate. On basis analysis data, sensitivity gallium to loading rate higher compared other environmental factors. In addition, this also includes several experiments for microscopic...
Abstract. Proceeding with the analysis of Amata et al. (2005), we suggest that general feature for local transport at a thin magnetopause (MP) consists penetration ions from magnetosheath gyroradius larger than MP width, and that, in crossing it, transverse potential difference current sheet (TCS) is acquired by these ions, providing field-particle energy exchange without parallel electric fields. It suggested part surface charge self-consistently produced deflection course inertial drift...
