Due Diligence Regulation and Sustainability Governance in Value Chains: Lessons From the South African Wine Sector

open access: yesRegulation &Governance, EarlyView.
ABSTRACT A recent raft of due diligence regulation (DDR) addressing social and environmental conditions in global value chains (GVCs) has spread across the UK and Europe. An emerging literature on DDR highlights the politics of its formation. Yet, we know little about how existing sustainability governance along GVCs interacts with DDR or the wider ...

Asymmetrical Chattering Arc in Vertical Plane Flight

open access: yes, 2013
The asymmetrical chattering arc of a winged space vehicle in the vertical plane reentry flight has been studied. With the use of dimensionless variables, we need only two parameters to specify the aerodynamic characteristics of the vehicle, one is the ...

Impact of switching functions on sliding mode observer in sensorless PMSM drives

open access: yesTạp chí Khoa học và Công nghệ
The Sliding Mode Observer (SMO) algorithm has emerged as a promising solution for estimating the position and speed of motors, effectively replacing traditional physical sensors.

Proto‐Panic Modulation by Caffeine‐Proteinoid Complexes

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 41, November 5, 2026.
Caffeine–proteinoid microspheres synthesized by thermal polymerization exhibit compartmentalized drug loading with encapsulation efficiencies of 61%–82% and triphasic release kinetics. Electrochemical monitoring reveals multi‐scale oscillatory dynamics consistent with chaotic and damped harmonic behavior, while Boolean logic operations demonstrate ...

Learning Rocking Dynamics From Sparse Shake‐Table Data With Interpretable Physics‐Informed Neural Networks

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 12, Page 3115-3136, 10 October 2026.
ABSTRACT We present a hybrid interpretable Physics‐Informed Neural Network Long‐Short Term Memory (Hybrid PINN LSTM) framework for predicting the seismic response of rocking blocks. Existing analytical models rely on uncertain idealizations, while purely data‐driven and machine‐learning approaches lack physical consistency and interpretability.

A load estimator based-fast terminal super-twisting control strategy for performance improvement of induction machine system drive

open access: yesJournal of Applied Science and Engineering
In this work, a hybrid control strategy derived from the control literature for induction machines is proposed, where a sliding-mode controller paired with an estimator from the same function is incorporated to provide fast, robust speed regulation while

When a Week Is Not A Week: How Temporal Boundaries Shift Regulatory Focus and Consumer Preference

open access: yesPsychology &Marketing, Volume 43, Issue 10, Page 2569-2587, October 2026.
ABSTRACT Does consumer perception of a sales event change if it falls across a calendar boundary (e.g., next month) versus within the current month, holding objective time constant? We investigate this question in the context of Cyber Monday, the global shopping event occurring the Monday after the U.S. Thanksgiving holiday.

Enhanced Control of 1.5 MW DFIG Generators in MRWT Systems Using GA‐Based PI‐ST‐SMC: Comparative Assessment With ST‐SMC

open access: yesWind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT This paper proposes a novel genetic algorithm‐based proportional–integral super‐twisting sliding mode control (GA‐PI‐ST‐SMC) strategy for the rotor‐side converter of a 1.5 MW doubly‐fed induction generator (DFIG) operating in marine renewable wind turbine (MRWT) systems.

A Two Degree of Freedom Approach for Discrete‐Time Sliding Mode Control

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 13, Page 6540-6551, 10 September 2026.
ABSTRACT This paper proposes a new two degree of freedom (2‐DOF) framework for discrete‐time sliding mode control (DSMC) that decouples the disturbed evolution from its nominal counterpart. The novel nominal/disturbed subsystem separation for DSMC can be used to define multiple closed‐loop specifications. The nominal regulation (or tracking) controller
