Scalable Approximation of the Transformation‐Free Linear Simplicial–Simplicial Regression via Constrained Iterative Reweighted Least Squares

open access: yesStatistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 4, August 2026.
ABSTRACT Simplicial–simplicial regression concerns statistical modeling scenarios in which both the predictors and the responses contain vectors constrained to lie on the simplex. Fiksel et al. introduced a transformation‐free linear regression framework for this setting, wherein the regression coefficients are estimated by minimizing the Kullback ...

Converting an Integer to a Decimal String in Under Two Nanoseconds

open access: yesSoftware: Practice and Experience, Volume 56, Issue 8, Page 963-977, August 2026.
ABSTRACT Objective Converting binary integers to variable‐length decimal strings is a fundamental operation in computing. Conventional fast approaches rely on recursive division and small lookup tables. The goal of this work is to develop a significantly faster method for this task.

Data‐Driven Emulation of Numerically Simulated Baltic Sea Surface Currents With a Deep Convolutional U‐Net: Explainability and Potential Forecast Skill

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Ocean models can represent surface circulation at kilometer scales, but their computational cost limits broad experimentation. We present DeepCUN, a deep convolutional encoder–decoder (U‐Net) that emulates daily mean Baltic Sea surface current components on a 1‐nautical‐mile grid.

Parameter‐Preserving Real‐time BIM Rendering via Direct GPU Ray Tracing

open access: yesComputer Animation and Virtual Worlds, Volume 37, Issue 4, July/August 2026.
Parametric BIM geometry is preserved from Revit extraction to GPU ray tracing without mesh tessellation. A two‐tier cache reuses repeated geometry during export, and an instanced OptiX representation reduces memory at render time. The method lowers export time and GPU memory while preserving exact curved surfaces.

An Optimal Edge Data Caching Scheme Based on Improved Particle Swarm Optimization

open access: yesConcurrency and Computation: Practice and Experience, Volume 38, Issue 13, July 2026.
ABSTRACT Mobile Edge Computing (MEC) alleviates the performance bottlenecks of traditional cloud computing in latency‐sensitive scenarios by moving computational resources to network edge nodes. In recent years, numerous research efforts have focused on developing edge data caching (EDC) strategies that enable app vendors to enhance caching performance

FuzzyMind: A Web Platform for End‐to‐End Fuzzy Cognitive Map Modeling

open access: yesConcurrency and Computation: Practice and Experience, Volume 38, Issue 14, July 2026.
ABSTRACT Fuzzy cognitive maps (FCMs) are widely used for modeling complex causal systems under uncertainty. However, the FCM development lifecycle, encompassing data preprocessing, model construction, weight optimization, and scenario analysis, is typically fragmented across heterogeneous tools.
