Δ9 Tetrahydrocannabinol and cannabis extracts differentially improve adipoinsular dysfunction in diet‐induced obesity

The Journal of Physiology, EarlyView.
Abstract figure legend THC and extract administered to diet‐induced obese mice reduced body weight and fat storage. Extract, but not THC, improved glucose clearance by a mechanism that may include restoring adipoinsular function. Abstract Diet‐induced obesity (DIO) is associated with dysregulated adipoinsular axis and endocannabinoid system (eCBS ...

Application of Cooperative Control of Discrete‐Time Nonlinear Multi‐Agent Systems Based on Extended Kalman Unknown Input Observer

Vector: The Journal of Engineering, Volume 2027, Issue 1, January/December 2027.
This study is concerned with the application of consensus control to a class of discrete‐time nonlinear multi‐agent systems with unknown inputs and additive noise. The aim is to design an extended Kalman unknown input observer (EKUIO) such that the state vector of a discrete‐time nonlinear system can be estimated, additive noise can be mitigated, and ...

Creativity Under Pressure: A Case Study of Drug Cartel Innovation

The Journal of Creative Behavior, Volume 60, Issue 4, December 2026.
ABSTRACT This article examines drug cartels as creative, innovation‐driven organizations rather than solely violent criminal enterprises. Building on creativity research applied to terrorist groups, we use a qualitative case study approach—drawing from news reports, official documents, open‐source materials, and academic work—to analyze 10 cases of ...

Optimality for underwater vehicle's

Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002
We study the time-optimal trajectories for fully actuated planar underwater vehicles, with constraints on input forces. Using the maximum principle, we focus on the structure of singular extremals and their possible optimality.

Avoidance of underwater cliffs for autonomous underwater vehicles

IEEE/RSJ International Conference on Intelligent Robots and System, 2003
This paper introduces a method aiming to allow underactuated autonomous underwater vehicles navigating in an unknown environment to avoid underwater cliffs. Three electro-acoustic transducers situated in the front part of the vehicle provide bathymetric data.

Underwater Robots: From Remotely Operated Vehicles to Intervention-Autonomous Underwater Vehicles

IEEE Robotics & Automation Magazine, 2019
Remotely operated vehicles (ROVs) revolutionized the subsea industry when they were introduced in the 1960s. They were more powerful and inherently safer, and they could go deeper than divers. However, they require a tether and a support ship, which makes their use complex and expensive.

Framework for Combining Multiple Lightweight Underwater Vehicles into Super Underwater Vehicle

2020 IEEE/OES Autonomous Underwater Vehicles Symposium (AUV)(50043), 2020
This paper investigates the potential of using multiple, rigidly interconnected lightweight underwater vehicles (LUVs) as a cheaper alternative to using a single vehicle for mapping and monitoring. The objective is to develop a prototype super underwater vehicle (SUV) demonstrating the proficiency of the multi-vehicle approach.
