Convergence-guaranteed time-varying RRT path planning for profiling floats in 4-Dimensional flow

, 2014
This paper presents an extension to the Rapidly-exploring Random Tree (RRT) algorithm applied to autonomous, drifting underwater vehicles. The proposed algorithm is able to plan paths that guarantee convergence in the presence of time-varying ocean ...

Linezolid‐induced lactic acidosis in critically ill patients: A multicentre study of incidence, severity and predictors

British Journal of Clinical Pharmacology, Volume 92, Issue 7, Page 2239-2249, July 2026.
Abstract Introduction Linezolid, a synthetic oxazolidinone for resistant gram‐positive infections, is generally associated with mild adverse effects such as gastrointestinal disturbances, but more serious reactions like lactic acidosis (LA) have also been reported.

Neuroendocrine Transformation Without PSA Elevation in High‐Risk Metastatic Castration‐Sensitive Prostate Cancer Under Androgen Receptor Signaling Inhibition: A Case Report

IJU Case Reports, Volume 9, Issue 4, July 2026.
ABSTRACT Introduction Neuroendocrine prostate cancer is a rare and highly aggressive variant of prostate cancer with a poor prognosis. We report a case in which metastatic castration‐sensitive prostate cancer directly transformed into neuroendocrine prostate cancer without a corresponding increase in prostate‐specific antigen.

Association between glycemic variability and acute kidney injury incidence in patients with cerebral infarction: an analysis of the MIMIC-IV database

Frontiers in Endocrinology
IntroductionGlycemic variability (GV) is an increasingly important predictive indicator of vascular occlusion-related complications. Studies have demonstrated that a higher GV is associated with poor outcomes in patients with cerebral infarction (CI ...

Abstract Augmented Lazy Theta*: Applying Graph Abstractions to Trajectory Planning with Speed-Limit Constraints

, 2014
Trajectory planning is a generalisation of path planning in which velocity is also taken into consideration. Considering velocity, in the context of a real-world system such as a robotic vehicle, means considering physical constraints such as the ...

Synthesis, Solubilization, and Photophysical Properties of Polyfluorinated Pentacene Dimers

Journal of Physical Organic Chemistry, Volume 39, Issue 7, July 2026.
The synthesis and photophysical analysis of polyfunctionalized pentacene dimers is described. Polyfluorination is employed to modulate the polarizability and to investigate the effects on the mechanism of singlet fission (SF). ABSTRACT A polyfluorinated pentacene dimer, linked with a 1,3‐diethynylphenylene spacer, was synthesized to investigate the ...

Real-Time Path Planning using a Simulation-Based Markov Decision Process

, 2011
This paper introduces a novel path planning technique called MCRT which is aimed at non-deterministic, partially known, real-time domains populated with dynamically moving obstacles, such as might be found in a real-time strategy (RTS) game.

Improved Simulations of the Quasi‐Biennial Oscillation in the Lower Stratosphere of an Earth System Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Numerical experimentation using an atmospheric configuration of the Goddard Earth Observing System (GEOS) Earth System Model is used to examine the vertical structure of the simulated Quasi‐Biennial Oscillation (QBO). Using an improved representation of the parameterized gravity wave spectrum, it is demonstrated that with sufficient vertical ...
