Inferring Inter‐Well Fracture Interactions in Unconventional Reservoirs Using Fiber‐Optic Sensing and Coupled Multiphysics Modelling

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Integrating distributed temperature sensing (DTS) and distributed acoustic sensing (DAS) data with numerical simulations to analyze inter‐well interference and production responses remains challenging. This study employs a coupled thermal–hydraulic–mechanical simulation framework to model heat transfer, fluid flow, and geomechanical responses ...

Automatic insect identification, counting, and monitoring techniques: a review

Pest Management Science, EarlyView.
Automated insect monitoring increasingly integrates optical, acoustic, infrared, radar, electrostatic, and biosensing technologies with artificial intelligence. No single approach is universally optimal; reliable deployment depends on task‐specific validation, representative datasets, robustness under field conditions, energy autonomy, connectivity ...

Characterization of Rain Attenuation for Millimeter Wavelengths for Realistic Nonrotational Symmetric Drop Shapes

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The use of frequencies above 30 GHz (millimeter waves) for communication purposes is nowadays a necessity, both for terrestrial (e.g., 5G/6G) and satellite links. One reason is the need for more bandwidth and the fact that “traditional” frequency bands are already fully occupied.

Optimizing electron backscatter diffraction of carbonate biominerals—resin type and carbon coating [PDF]

, 2009
Electron backscatter diffraction (EBSD) is becoming a widely used technique to determine crystallographic orientation in biogenic carbonates. Despite this use, there is little information available on preparation for the analysis of biogenic carbonates ...

Remote Plasma‐Enabled Vertical Asymmetry Engineering of 2D PtSe2 via Phase‐Preserving Chalcogen Exchange

Small, EarlyView.
Remote H2S plasma enables temperature‐controlled chalcogen exchange in PtSe2. At 50°C, selective top‐surface Se‐to‐S substitution yields Janus PtSSe while preserving the layered framework, whereas treatment at 200°C promotes further sulfur incorporation and diffusion to form PtS2.

Impact of tissue heterogeneity on intracranial Cesium‐131 brachytherapy dosimetry: A patient‐specific Monte Carlo Study

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background AAPM TG‐43‐based dose calculations for intracranial cesium‐131 (131Cs) brachytherapy ignore patient‐specific heterogeneities, which can affect dose accuracy. This study investigates the dosimetric impact of these heterogeneity effects using Monte Carlo (MC) simulations and patient‐specific imaging data.
