We present a molecular dynamics study of the liquid and plastic crystalline phases of CCl 3Br. We investigated the short-range orientational order using a recently developed classification method and we found that both p...

Abstract Complex systems often involve interactions within groups, namely higher-order networks, rather than simple pairwise connections, which fundamentally reshape how collective dynamics unfold. However, it remains po...

Abstract Industrial emissions are significant contributors to global air pollution, particularly with respect to PM2.5 and CO2 emissions. It remains one of the most pressing environmental challenges globally, driven larg...

We investigate the nature of memory effects in the non-Markovian dynamics of spin-boson models. Local quantum memory criteria can be used to indicate that the reduced dynamics of an open system necessarily requires a qua...

The interactions of proteins with membrane surfaces are important to many biological processes, including signaling, recognition, and membrane trafficking, cell division and cell structure. When the Fluid Mosaic Model (F...

A family of evolution equations describing a power-law nonlinear diffusion process coupled with a local Verhulst-like growth dynamics, and incorporating a global regulation mechanism, is considered. These equations admit...

Despite having >1200 described species and despite their nearly worldwide distribution and prevalence in many xeric ecosystems, relative to many other arachnid groups, we know little about the natural history and behavio...

We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼1014 M from the cosmological hydrodynamical simulation Illustris and follow their...

Accelerated molecular dynamics and quantum conductance calculations are employed to shed light onto the electrochemical properties of the Au|1,8-octanedithiol|Au junction. Widely different contact geometries with varying...

The introduction of an exotic species usually modifies parasite–host dynamics by the import of new parasites or the exotic species' acquiral of local parasites. The loss of parasites may determine the outcome of an inv...

UDP-glucose:glycoprotein glucosyltransferase (UGGT) flags misfolded glycoproteins for ER retention. We report crystal structures of full-length Chaetomium thermophilum UGGT (CtUGGT), two CtUGGT double-cysteine mutants, a...

Coastal ecosystems such as mangroves, seagrasses, and coral reefs are highly sensitive to shoreline instability and rapid land-use changes in industrializing regions. Nayband Gulf, located adjacent to the Pars Special Ec...

IntroductionStudent engagement is a pivotal element in educational psychology, significantly impacting learning outcomes and academic achievement. Traditional methods for analyzing student engagement often rely on static...

Poa ligularis es una forrajera importante en los pastizales de la Patagonia. Las poblaciones de esta gramínea cespitosa perenne han sido afectadas severamente por el sobrepastoreo. En este estudio proponemos que increme...

Abstract Due to the complex structures of multi-limbed parallel robots, conventional parallel robots generally have limited workspace, complex kinematics, and complex dynamics, which increases the application difficulty ...

Abstract This study investigated how joint dynamics and kinematics change with increasing squat intensity in elite powerlifters performing the powerlifting-style low-bar back squat. Twenty-nine national- and internationa...

Abstract Background Blanket bogs are rare ombrotrophic peatlands that function as important long-term carbon stores. Their persistence depends on strong nutrient limitation, which maintains Sphagnum dominance and suppres...

The purpose of this study was to assess hydrological controls (e.g., rainfall, irrigation practices, river discharge, dam operation, evaporation) on surface (SW)- ground water (GW) interactions in an irrigated valley wit...

Abstract In the present paper we study the relationship between the notions of force, cause and subject of motion in Leibniz’s early dynamics. First, we specify the role that the problem of the subject and cause of mot...

Rapid climatic changes and increasing human influence at high elevations around the world will have profound impacts on mountain biodiversity. However, forecasts from statistical models (e.g. species distribution models)...

Nuestro objetivo fue investigar el desarrollo larval de Argia joergenseni Ris en tres arroyos ubicados en diferentes latitudes y ecorregiones (Yungas y Chaco) en Argentina. Medimos el ancho de la cabeza y la longitud de ...

In the era of single-particle cryogenic electron microscopy (cryo-EM) and AI-driven protein structure prediction, obtaining high-resolution protein structures, either experimentally or computationally, has become increas...

Sulfur dioxide (SO2) is a major atmospheric pollutant in China, and understanding its spatiotemporal dynamics is essential for effective air quality management. Using hourly SO2 data from more than 2000 urban monitoring ...

The most important task at the present stage remains the transition to sustainable regional development. For the Far East regions, such a transition is becoming more relevant due to the current social and economic challe...
