Bootstrap Tests for Nonlinear Simplex Models
Stat, Volume 15, Issue 1, March 2026.ABSTRACT We provide important contributions regarding hypothesis tests on the class of nonlinear simplex regression models. The performance of traditional asymptotic tests based on the maximum likelihood estimation (MLE) tends to exhibit considerable size distortions in finite samples.

Beyond Core‐Periphery: A Multidimensional Typology of Brazilian Regional Inventive Capacity
Growth and Change, Volume 57, Issue 1, March 2026.ABSTRACT The geography of invention in Brazil is characterized by a profound and multi‐polarised structure that extends beyond a simple core‐periphery dichotomy. This paper demonstrates this complexity through a multidimensional analysis of inventive capacity (2000–2023), operationalised along four axes—‘how much’, ‘who’, ‘how’, and ‘what’ is invented ...

physica status solidi (a), Volume 223, Issue 3, 6 February 2026.Cd1−x−yMnxCry (x = 0.33, 0.05 ≤ y ≤ 0.15) quaternary semiconductors were synthesized by direct fusion and characterized by XRD/Rietveld refinement and SEM. All compositions crystallize in the zinc blende structure, exhibiting a systematic lattice contraction with increasing Cr content, evidencing partial Cd substitution, accompanied by marked ...

Conformal Coordinates for Molecular Geometry: From 3D to 5D
Journal of Computational Chemistry, Volume 47, Issue 4, February 5, 2026.The figure illustrates the conformal representation of ℝ3$$ {\mathbb{R}}^3 $$ in a non‐Euclidean five‐dimensional space ℍ$$ \mathbb{H} $$. Each point x∈ℝ3$$ x\in {\mathbb{R}}^3 $$ is described with two additional vectors, e0$$ {e}_0 $$ and e∞$$ {e}_{\infty } $$, so that Euclidean distances in ℝ3$$ {\mathbb{R}}^3 $$ can be recovered via inner products ...

Stall‐Free Asynchronous State Repartitioning With a Proactive Workload Tracking Window
Concurrency and Computation: Practice and Experience, Volume 38, Issue 3, February 2026.ABSTRACT High‐throughput stateful applications rely on dynamic data repartitioning to adapt to changing workloads, but this process presents significant challenges. This paper provides a detailed analysis of such challenges, drilling down into the tradeoffs between adaptation, computational overhead, and service availability. We identify that a primary
