Watchman routes under limited visibility [PDF]

open access: yes, 1992
In this paper we consider the watchman route problem in simple polygons when there is a distance limit (range) d to the visibility of the watchman. We have then two versions of the watchman route problem. We want to find a shortest route such that either

AI‐Assisted Recognition of Actual Ureteral and Pancreatic Injuries in Laparoscopic Colorectal Surgery: A Randomized Video Review Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
AI‐generated anatomical highlighting improved surgeons' recognition of actual ureteral injuries during laparoscopic colorectal surgery, including recognition within predefined injury time‐code windows. No significant overall improvement was observed for pancreatic injury, and incorrect adverse‐event judgments did not increase in no‐injury videos. These

Can Chemoradiotherapy Expand Immune Checkpoint Blockade Responsiveness in Mismatch Repair‐Proficient Rectal Cancer?

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Immune checkpoint blockade (ICB) has transformed the treatment of mismatch repair‐deficient (dMMR) colorectal cancer but produces no meaningful benefit in advanced mismatch repair‐proficient (pMMR) disease. In the neoadjuvant setting, however, pathological responses have been reported in a subset of pMMR tumors, suggesting that clinical ...

Interactive Prompt‐Guided Robotic Grasping for Arbitrary Objects Based on Promptable Segment Anything Model and Force‐Closure Analysis

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A laser pointer‐guided robotic grasping method for arbitrary objects based on promptable segment anything model and force‐closure analysis is presented. Grasp generation methods based on force‐closure analysis can calculate the optimal grasps for objects through their appearances. However, the limited visual perception ability makes robots difficult to

Extending Battery Usage Time of a Heavy‐Duty Mecanum‐Wheeled Autonomous Electric Vehicle Used in Iron–Steel Industry by Considering Wheel Slippage

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
It is a fact that slippage causes tracking errors in both longitudinal and lateral directions which results to have less travel distance in tracking a reference trajectory. Less travel distance means having energy loss of the battery and carrying loads less than planned.
