A Python Algorithm for Shortest-Path River Network Distance Calculations Considering River Flow Direction

Data, 2020
Vector based shortest path analysis in geographic information system (GIS) is well established for road networks. Even though these network algorithms can be applied to river layers, they do not generally consider the direction of flow.

A dual gating mechanism controls target‐strand cleavage in Cas12j: Implications for engineering efficient nickases

Protein Science, Volume 35, Issue 10, October 2026.
Abstract The rapid expansion of CRISPR technologies has unveiled a diverse repertoire of RNA‐guided endonucleases, among them the compact Cas12j, which has emerged as a promising genome‐editing tool. Cas12j cleaves the two DNA strands sequentially; however, the molecular mechanism that regulates this cleavage remains incompletely understood.

Deep Reinforcement Learning Based Autonomous Decision‐Making for Cooperative Uncrewed Aerial Vehicles: A Search and Rescue Real World Application

Journal of Field Robotics, Volume 43, Issue 7, Page 4382-4401, October 2026.
ABSTRACT This paper presents the first end‐to‐end framework that combines guidance, navigation, and centralized task allocation for multiple UAVs performing autonomous search‐and‐rescue (SAR) in GNSS‐denied indoor environments. A twin delayed deep deterministic policy gradient controller is trained with an artificial potential field (APF) reward that ...

Bidirectional Dijkstra’s Algorithm is Instance-Optimal

Fixed a bug in the bidirectional search pseudocode where e_mid was updated even if $\mu$ wasn't. Fixed a typo in the proof of Theorem 3: changed all $v_1u_2$ to $u_2v_1$.

Automated Lawn Maintenance: An Agronomic and Operational Review of Turf Health, Biodiversity, and Field Performance

Journal of Field Robotics, Volume 43, Issue 7, Page 4603-4623, October 2026.
ABSTRACT Grass mowing is one of the most resource‐consuming activities in green maintenance, whether in private areas such as home gardens or in public spaces like urban parks. In recent years, concerns related to climate change, human health, and sustainability have become increasingly prominent in green maintenance, leading manufacturers and industry
