Coherence‐Preserving Fluctuation Diagnostics for an Engineered Population‐Inverted Qubit Otto Engine

ABSTRACT Finite‐time quantum thermal machines require diagnostics beyond average work and efficiency because microscopic engines operate where fluctuations, incomplete thermalization, and coherence strongly affect performance. A coherence‐preserving fluctuation diagnostic is deve...

Bjorken flow of holographic R-charged plasmas

Abstract We numerically investigate the time evolution of several physical observables for the so-called 2 R-Charge Black Hole (2RCBH) model undergoing Bjorken flow. The 2RCBH model corresponds to a top-down holographic construction describing a strongly interacting conformal flu...

Subsampled cubic regularization method with distinct sample sizes for function, gradient, and Hessian

Abstract We develop and study a subsampled cubic regularization method for finite-sum composite optimization problems, in which the function, gradient, and Hessian are estimated using possibly different sample sizes. By allowing each quantity to have its own sampling strategy, th...

Factors associated with discordance between the patient-reported Rheumatoid Arthritis Disease Activity Index (RADAI) and the Simplified Disease Activity Index (SDAI) concerning the achievement of treat-to-target goals – data from the REAL study

Abstract Background Treat-to-target (T2T) strategies in rheumatoid arthritis (RA) rely on regular assessment of disease activity using validated composite indices, with remission or low disease activity as therapeutic goals. The Simplified Disease Activity Index (SDAI) is widely...

Definition of Charging Fee for Drainage Services and Incentives Based on LID Simulation

Given the scarcity of initiatives to charge for urban stormwater services in Brazil and the need to recognise users’ efforts in adopting technologies such as Low Impact Development (LID), a proposal was developed for a stormwater drainage fee and incentives for environmental serv...

A Semi-Empirical Method for Estimating All-Sky Photosynthetically Active Radiation from Sentinel-2 for High-Resolution Land Surface Analysis

Photosynthetically active radiation (PAR) is a fundamental driver of terrestrial photosynthesis and a key input for light use efficiency-based estimates of gross primary productivity (GPP). However, existing PAR products are typically designed for regional to global applications...

School-based sexual violence prevention: A systematic review

Purpose Sexual violence profoundly affects the health and development of children, adolescents, and young adults, representing a persistent challenge to public policy. This systematic review examined the effectiveness of school-based interventions aimed at prevention. Methods Eig...

MSSiS 2026: Report on the EighthWorkshop on Modeling and Simulation of Software-Intensive Systems

In this paper, we report on the outcomes of the Eighth Workshop on Modeling and Simulation of Software-Intensive Systems (MSSiS 2026), held in conjunction with the 48th International Conference on Software Engineering (ICSE 2026), in Rio de Janeiro, Brazil, on April 12th 2026. Th...

Enhanced pozzolanic activity of microcrystalline cellulose via silane modification for cementitious composites

Abstract This study evaluated the effect of surface functionalization of microcrystalline cellulose (MCC) with tetraethyl orthosilicate (TEOS) on its physicochemical properties and the performance of cement-based microconcretes incorporating the modified material. Eleven MCC samp...

Data and channel-aware device selection for split learning in resource-constrained B5G/6 G networks

Abstract Split learning (SL) is a promising distributed learning approach for fifth-generation/sixth-generation (B5G/6 G) networks. However, its performance is affected by bandwidth constraints and statistical heterogeneity in the data. Prior works have considered either channel-...

Landscape history matters: decoupled responses of plant taxonomic, phylogenetic and functional diversity to intensive agriculture impacts in Cerrado

Loss of woody plants due to intensive agricultural expansion is particularly critical because of their role in ecosystem functions and services, as well as in ecosystem resilience. Therefore, understanding the effects of landscape changes on multiple dimensions of biodiversity (i...

Pilot-scale optimization of atmospheric acid leaching for enhanced nickel and cobalt recovery from laterite ore

Nickel and cobalt are critical metals predominantly extracted from laterites. However, deposits with high iron content (>15%) and SiO2/CaO + MgO ratios (∼1.8) limit the applicability of conventional pyrometallurgical routes. In this scenario, hydrometallurgical processes, particu...

A Busemann Hybrid Projection-Proximal Point Algorithm for Optimization Problems on Hadamard Manifolds

Abstract We study convex optimization problems on Hadamard manifolds and propose a projection based variant of the proximal point algorithm, called the Busemann hybrid projection-proximal point algorithm . The method replaces Euclidean hyperplanes by horospheres defined through B...
