Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Modeling, simulation, and control of soft robots using Koopman operator theory

, 2023
In nature, animals with soft body parts can control their parts to different shapes, e.g., an elephant trunk can wrap on a tree branch to pick it up. But most research on manipulators only focuses on how to control the end effector, partly because the arm of the manipulator is rigidly articulated.

Seek and Ye Might Not Find: The Effects of Contract Framing on Knowledge Sharing and Knowledge Seeking Qui cherche ne trouve pas toujours : les effets liés à la formulation des contrats sur le partage et la recherche de renseignements

Contemporary Accounting Research, EarlyView.
ABSTRACT We conduct two experiments to examine whether and how the framing (bonus vs. penalty) of a target‐based incentive contract affects knowledge sharing and knowledge seeking. In the first experiment, we predict and find that penalty‐framed contracts increase employees' stress due to the fear of potential loss, which in turn reduces their ...

Koopman operator learning using invertible neural networks [PDF]

In Koopman operator theory, a finite-dimensional nonlinear system is transformed into an infinite but linear system using a set of observable functions.

Data-Driven Nonlinear Stabilization Using Koopman Operator [PDF]

, 2019
We propose the application of Koopman operator theory for the design of stabilizing feedback controller for a nonlinear control system. The proposed approach is data-driven and relies on the use of time-series data generated from the control dynamical ...

Running towards: Labour market incentives for runaway slaves in the British Cape Colony, 1830–1838

Asia‐Pacific Economic History Review, EarlyView.
Abstract Recent scholarship on slave escapes has increasingly emphasised economic motivation, but few studies have empirically investigated how market incentives influenced the decision‐making of enslaved individuals during transitions from coerced to wage labour.

Data-Driven Identification of Gas Turbine Engine Dynamics via Koopman Operator Genetic Algorithm

IEEE Access
Gas turbine engines (GTEs) are highly nonlinear control-nonaffine systems. Deriving their physics-based models can be challenging, particularly when some critical parameters can be difficult to measure or determine otherwise.

Pericapsular nerve group block with phenol for non‐operative hip fracture management in patients living with frailty: a prospective multicentre cohort study

Anaesthesia, EarlyView.
Summary Introduction The incidence of hip fractures is rising with the ageing population. For patients living with severe frailty and limited life expectancy, non‐operative management is increasingly considered after shared decision‐making. Given the limited availability of long‐term analgesic options, alternative techniques are needed.

Deep Bilinear Koopman Model for Real-Time Vehicle Control in Frenet Frame

IEEE Access
Accurate modeling and control of autonomous vehicles remain a fundamental challenge due to the nonlinear and coupled nature of vehicle dynamics. While Koopman operator theory offers a framework for deploying powerful linear control techniques, learning a
