Experimental Analysis and Physics‐Based Analytical Model on Twisted and Coiled Artificial Muscles
Advanced Engineering Materials, Volume 28, Issue 2, January 21, 2026.Twisted and coiled artificial muscles made from silver‐coated nylon fibers are investigated through experiments and analytical modeling. The actuators achieve contractions up to 19.3% and specific work of 8 kJ kg−1, though efficiency remains limited (≈0.15%) by thermal losses.

One‐Dimensional Finite Elements With Arbitrary Cross‐Sectional Displacement Fields
International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.ABSTRACT This paper introduces an unprecedented unified approach for developing structural theories with an arbitrary kinematic variable over the beam cross‐section. Each of the three displacement variables can be analyzed using an independent expansion function. Both the order of the expansion and the number of terms in each field can be any. That is,

Population Ecology, Volume 68, Issue 1, January 2026.We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Applied Cognitive Psychology, Volume 40, Issue 1, January/February 2026.ABSTRACT This study examined the effectiveness of two instructional methods for teaching fraction multiplication within the framework of cognitive load theory. Ninety‐three Year 4 students from South East Asian country were randomly assigned to either the High Element‐Interactivity Method (HEIM) or the Low Element‐Interactivity Method (LEIM).

Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel
Advanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

Advanced Sensor Research, Volume 5, Issue 1, January 2026.This work provides solutions for force sensor and system miniaturization and modularization solution, which supports function expansion on existing mechanical robots. Compared with a prior solution, 87% volumetric reduction is realized with less than 2% signal tolerance and remarkable repeatability.
