Comparative Analysis of Surface Roughness and Geometric Tolerances in Material Extrusion: CPE versus TPU

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
This work presents the first systematic comparison of dimensional tolerances and surface roughness in CPE and TPU parts fabricated by Material Extrusion. A shared DOE framework reveals a strong linear link between layer height and Ra roughness, highlights wall‐count impacts on geometric accuracy, and uncovers TPU's higher sensitivity to infill ...

Spectroscopic Signatures of Doping in Thin Films of Semiconducting Single‐Walled Carbon Nanotubes

open access: yesSmall, Volume 22, Issue 28, 18 May 2026.
This review presents an overview of the spectroscopic changes of semiconducting single‐walled carbon nanotubes upon chemical, electrochemical or electrostatic doping. The presence of holes or electrons directly affects visible to far‐infrared absorption, near‐infrared fluorescence and electroluminescence as well as Raman spectra, which enables in‐situ ...

Quantifying Structural Complexity, Effort, and Performance: An Early Experiment Using Network Design Tasks

open access: yesSystems Engineering, Volume 29, Issue 3, Page 387-405, May 2026.
ABSTRACT Structural Complexity is perceived as driving cost in system development, yet managing it effectively requires empirical understanding. This study investigates human decision‐making using a toy transportation‐style network design task, focusing on how Structural Complexity, Effort, and Performance interact. Seventy‐four participants (primarily

Landscape features predict broad‐scale seed rain patterns across fragments of the Brazilian Atlantic Forest

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Along with precipitation, forest cover emerges as a fundamental driver of alpha and beta diversity in the seed rain. This highlights the role of habitat amount at the landscape level over patch‐level features, like patch size, for seed dispersal. However, increased seed density can be related to higher dispersal rates in forest borders.

BIEN: A biodiversity informatics ecosystem advancing open and reproducible workflows for plant observation, plot and trait data

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 5, Page 1556-1584, May 2026.
Abstract The rapid expansion of biodiversity data presents new opportunities to understand and forecast biosphere dynamics. However, disparate and dispersed data, taxonomic and geographic inconsistencies, pervasive quality issues, and a lack of reproducable workflows hinder synthesis, introduce biases and limit accurate assessment of biodiversity ...

Evidence of emerging transcriptome mediators of Alzheimer's disease in canine cognitive dysfunction

open access: yesBrain Pathology, Volume 36, Issue 3, May 2026.
Canine cognitive dysfunction (CCD) may be a promising model of Alzheimer's disease (AD). To assess AD‐related molecular signatures in CCD, we generated transcriptome data on dog cortex and plasma extracellular vesicles (EVs). CCD‐related transcriptome changes were similar to those in aging/AD humans and were detectable in EVs from the same animals ...
