NB-Net: A Biologically-Inspired Framework for Neural Network Width Expansion

Abstract Deep learning has achieved remarkable success across various fields, however, most research in this area has primarily focused on increasing network depth, leading to a relative lack of systematic exploration of network width. Inspired by the structure of biological neur...

Amortized inverse kinematics via graph attention for real-time human avatar animation

Inverse kinematics (IK) is a core operation in animation, robotics, and biomechanics: given Cartesian constraints, recover joint rotations under a known kinematic tree. In many real-time human avatar pipelines, the available signal per frame is a sparse set of tracked 3D joint po...

Screen time is differentially related to visual selective attention and visual feature processing across middle childhood

Abstract Increased screen time has been linked to attention difficulties in early childhood, raising concerns among parents and professionals. However, it remains unclear how screen use influences the development of visual attention and visual processing across childhood. In this...

Quality assessment of malaria microscopy in Ouagadougou laboratories, Burkina Faso: accuracy of thick and thin blood smears

Abstract Background Malaria microscopy remains the reference method for parasite detection in many low-resource settings, but its accuracy depends on slide preparation, staining quality, and reader performance. Objective This study aimed to assess the accuracy of routine malaria...

Exact rotating dilatonic branch in ModMax electrodynamics without Maxwell analogue

Abstract We present a novel class of rotating dilatonic solutions within the framework of Einstein–ModMax-type gravity. The configuration belongs to the nonlinear sector characterized by $$\mathcal F/\mathcal G=\textrm{const}$$ F / G = const and carries nontrivial electric and ma...

Unification of Cosmological Evolution: From the Planck Scale to the Asymptotic Regime — A Unified Scaling Description Governed by ε(t) within Standard Physics

This work develops a minimal formalism that unifies cosmological evolution and diverse physical domains through a set of interconnected relations and a single underlying scaling structure.Within this framework, global properties of the Universe emerge directly from established ph...

Making the Case for an Experiential Approach to Test Validation

This paper introduces the Experiential Approach to test validation (Araneda, 2023; Araneda & Sireci, 2021), a framework grounded in phenomenology, rhetorical argumentation, and participatory epistemologies. Departing from traditional validation models centered on psychometric inf...

Sparse semi-interpretable networks for discovering nonlinear dynamics with time-varying parameters and switching structures

Data-driven equation discovery has emerged as a new focal point in nonlinear dynamics. While significant progress has been made in identifying governing equations of time-invariant dynamical systems, the existing approaches still encounter considerable obstacles when applied to s...

The PMADS project: a longitudinal multimodal cohort study to understand risk for perinatal mood and anxiety disorders

Abstract Background Perinatal mood and anxiety disorders (PMADs) are among the most common and consequential complications of pregnancy. The perinatal period is also characterized by profound hormonal fluctuations and large-scale brain plasticity. However, the mechanisms linking...

Morphological State Transitions and Sediment Transport Variability in Braided Rivers

Abstract Sediment transport in braided rivers shows significant temporal variability, characterized by intense bursts of transport rates even under steady‐state conditions. These fluctuations are often viewed as the consequence of random variations in the local hydraulic conditio...

Mesozoic Microplates of East Asia: A New Reconstruction

Abstract The complex tectonic evolution and regional remagnetization in East Asia since the Mesozoic have led to debates over plate reconstructions. By synthesizing high‐quality paleomagnetic poles and geological data, this study develops a new plate reconstruction model for East...

Coupled effects of dissolved inorganic carbon dynamics and phytoplankton community succession rates on the biological carbon pump (BCP) in karst reservoirs

Karst reservoirs with high dissolved inorganic carbon (DIC) concentration exhibit an efficient biological carbon pump (BCP) effects driven by phytoplankton photosynthesis; however, the influence of phytoplankton community succession on BCP potential remains unclear. To address th...

Vulnerabilidad Organizativa Acumulativa (VOA) / Cumulative Organizational Vulnerability (COV): Theoretical and Conceptual Framework

Version 2.0 of the theoretical and conceptual framework of Cumulative Organizational Vulnerability (COV), originally formulated as Vulnerabilidad Organizativa Acumulativa (VOA). This version documents the conceptual evolution of the construct resulting from an expanded review of...

Extension of the particle finite element method towards quadrilateral-dominated meshes for large-deformation geotechnical problems

Particle Finite Element Method (PFEM) simulations frequently suffer from volumetric locking and remeshing-related inaccuracies when conventional first-order triangular finite elements are employed. In this contribution, a variant of the PFEM relying on quadrilateral-dominated mes...

Psychosocial support for mothers experiencing psychological stress in early childhood interventions: a mixed-methods evaluation in Austria

Abstract Background Psychological stress during pregnancy and early motherhood is a major public health concern with significant implications for maternal wellbeing and early child development. Persistent stress during this period can adversely affect maternal mental health, pare...

Aspartate-dependent polyamine biosynthesis in bacteria: chemical synthesis of carboxypolyamines and mechanism-based design of hydroxylamine-containing inhibitors of carboxyspermidine decarboxylase

Abstract Biogenic polyamines spermidine, spermine and some of their derivatives are small organic polycations vitally important in all domains of life. Recent studies have demonstrated that polyamine biosynthesis is subject to convergent evolution and that some bacteria employ bi...

The Structural Archive: A Universal Invariant for Physical and Logical Identity

Every discipline that reaches a sufficient depth of inquiry eventually encounters a structural boundary. Mathematics identifies such boundaries through incompleteness; physics through fundamental limits of scale; computation through undecidability; and cognition through the const...

synkit: a toolkit to create syntactic representations in Typst

synkit is a Typst package for drawing syntax trees from bracket notation. It supports a wide range of features, including triangles, arrows, movement traces, multidominance, semantic annotation, cross-tree equivalence lines, and formatting options for quick adjustments. Trees can...

Developing an Inventory of Workplace Stress Coping Strategies Among Autistic Adults: A Grounded Delphi Study

Abstract Background Stress levels are often elevated among autistic people, a pattern that also extends to the workplace. Effective coping strategies can reduce the negative impact of stress on work retention and overall wellbeing. However, the unique coping strategies of autisti...

Exploring the mediating role of working alliance in a peer support intervention for late-life depression

Objective: Peer support is an evidence-based intervention for depression, yet the mechanisms underlying its effectiveness remain understudied, particularly in randomized clinical trials. This study examined the mediating role of working alliance components (task, bond, and goal)...
