Cooling Holes in Polymer Spur Gears: A Critical Analysis of Heat Dissipation Benefits and Mesh Stiffness Penalties

Journal of Applied Polymer Science, Volume 143, Issue 38, October 10, 2026.
Cooling holes provide a simple passive cooling strategy for polymer spur gears, reducing maximum operating temperature by up to 9.39% while introducing a measurable gear mesh stiffness penalty. A validated response‐surface model reveals how hole size and location govern this thermal–mechanical trade‐off, enabling design optimization for thermally and ...

Seeing radiation: Applications of an imaging survey meter in radiation oncology

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background and purpose Radiation shielding surveys require location and evaluation of radiation hotspots in shielding barriers. This process is normally done by using a conventional survey meter and slowly moving the survey meter manually across the face of the barrier.

Correlation of size specific dose estimates with organ dose in abdominal spectral computed tomography

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background In abdominal spectral Computed Tomography (CT), organ dose assessment is important for radiation safety but remains challenging due to the complexity of Monte Carlo (MC) simulations. Purpose This study aimed to compare the correlations of three size‐specific dose estimate (SSDE) metrics (including the central slice SSDEcenter, the ...

Modal Analysis of Light Propagation, Polarization and Diffraction by Cholesteric Liquid Crystal Layers

Advanced Functional Materials, Volume 36, Issue 80, 5 October 2026.
The analysis of optical eigenmodes in chiral liquid crystal with perpendicular or tilted helical axis, and their correspondence with the external medium, leads to an intuitive understanding of the angle and wavelength dependency of transmissive and reflective diffraction.

Monolithic 3D‐Integrated All‐Solid Ion‐Gated Carbon Nanotube Transistors With Tunable Ionic Conductance for Multi‐Timescale Reservoir Computing

Advanced Materials, Volume 38, Issue 55, 1 October 2026.
A dual‐timescale reservoir based on monolithically 3D (M3D)‐integrated CNT solid ion‐gated transistors is demonstrated. Tunable ionic dynamics and pulse‐engineered operation enable linear and symmetric synaptic updates. The M3D‐integrated array achieves robust temporal encoding and accurate classification of moving MNIST sequences, highlighting its ...
