Gradient‐ and Newton‐Based Unit Vector Extremum Seeking Control

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper proposes new methods for stable and efficient convergence in multivariable extremum seeking control (ESC) using sliding mode techniques. Inspired by classical sliding modes and finite‐time control, the approach integrates these ideas into gradient‐ and Newton‐based ESC schemes with sinusoidal perturbations.

Sliding Mode Control and Observation for Upper Limb Robotics Rehabilitation

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Stroke is a leading cause of upper limb motor impairments, which often require rehabilitation. General purpose robotic manipulators enable effective therapy through exercises such as Center Out Point‐to‐Point (CO‐PTP) and Teach‐and‐Track (TT), which respectively demand accurate estimation and rejection of the interaction force exerted by the ...

Competition Policy and Achieving Sustainable Development Goal 1 (No Poverty): The Role of Mergers and Acquisitions Adjudications in South Africa

Sustainable Development, EarlyView.
ABSTRACT South Africa faces persistently high poverty and inequality alongside a highly concentrated economic structure, raising questions about whether merger control, especially public‐interest provisions, can contribute to poverty reduction. However, empirical evidence directly linking merger adjudication outcomes to poverty remains limited.

An Ergonomic Customizable Soft Robotic Glove Toward Personalized Hand Rehabilitation

SmartBot, EarlyView.
Soft robotic gloves for hand rehabilitation are often limited by poor fit and uneven pressure on the fingers. Here, the authors report an ergonomic all‐fabric glove whose dual‐action actuators are tailored to individual finger geometry by CNC heat sealing, with symmetrical chambers that distribute interface pressure more evenly. Weighing only 90 g, the

Liquid Phase Backscattered Scanning Electron Microscopy of Bacillus subtilis Spores

Small Methods, EarlyView.
Graphene encapsulation enables liquid‐phase BSE‐SEM to visualize subsurface architecture of whole, hydrated Bacillus subtilis spores without staining. This approach is applied to visualize dormant spores and subsequent structural changes during spore germination, while imaging across a range of beam energies and Monte Carlo simulations provide a ...

When Local Partner Knowledge Is Embedded: The Choice Between Greenfield and Acquisitive International Joint Ventures

Thunderbird International Business Review, EarlyView.
ABSTRACT This study investigates how embedded knowledge assets influence the strategic choice between greenfield and acquisitive international joint ventures (IJVs). Integrating transaction cost theory with a knowledge‐based view, we theorize that establishment mode decisions are driven not only by governance efficiency but also by the need to access ...
