Computational Modeling of Tetralayer Graphene/h‐BN/MoS2/Phosphorene Heterostructured Sensors for Real‐Time Fault Detection and Predictive Maintenance of High‐Voltage Power Transmission Lines

Advanced Physics Research, Volume 4, Issue 12, December 2025.
A fully simulation‐based study integrating graphene/h‐BN/MoS2/phosphorene heterostructures for fault detection in high‐voltage power lines. Coupled DFT‐FEA models predict mechanical, thermal, discharge, and EMI performance with >99.7 % accuracy. The work establishes a multi‐physics computational paradigm for predictive maintenance and digital‐twin ...

An Analysis of Packet Fragmentation Impact in LPWAN

, 2018
Packet fragmentation has mostly been addressed in the literature when referring to splitting data that does not fit a frame. It has received attention in the IoT community after the 6LoWPAN working group of IETF started studying the fragmentation headers

Trash Talking: Anthropogenic Resources Facilitate Raccoon Interactions in Urban Environments

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Interactions between conspecifics play a key role in ecological processes, and habitat modification, such as urbanization, can alter the spatial and social behaviors that underpin such interactions. Here, we used high‐resolution GPS data to examine how resource distribution affects raccoon contact in an urban greenspace in Brooklyn, NYC.

Skin‐Integrated Wearable Electronics: A Dual‐Interface Perspective

SmartSys, Volume 1, Issue 4, December 2025.
ABSTRACT Skin‐integrated wearable electronics enable continuous, medical‐grade monitoring and therapy in daily life, but must balance conflicting needs related to mechanics, power, and communication. This review uses a dual‐interface approach that separates the sensor–receiver interface, which handles wireless data and energy transfer, from the sensor ...

RiscBal, an Innovation Ecosystem Co‐Created From Physical Geography Research and Public Emergency Management in a Mediterranean Flood‐Prone Region

Journal of Flood Risk Management, Volume 18, Issue 4, December 2025.
ABSTRACT Flood events are the most common weather‐related hazard in Europe and Spain, comprising 41% of such events between 2001 and 2020. Mediterranean catchments, with steep slopes and short river courses, are particularly vulnerable to intense convective rainfall, often triggering flash floods.

LoRaWAN Network Performance Test

Acta Technica Jaurinensis, 2020
There are several types of wireless IoT (Internet of Things) networks based on the connection distance between two communicating devices. For covering wide areas, LPWAN (Low Power Wide Area) networks can provide a good solution. These networks provide big coverage and low power consumption.
