Quantum‐Mechanical Wave Functions in Singular Potentials: Linear and Nonlinear States

open access: yesAdvanced Physics Research, EarlyView.
The attractive singular potential −1/r2$-1/r^2$ gives rise to the quantum collapse in the 3D linear Schroedinger equation. The article summarizes theoretical results demonstrating suppression of the collapse and creation of the missing ground state (GS) in a gas of bosonic particles, carrying an electric dipole moment, which are pulled to the central ...

Polarization‐Dependence of Nonlinear Optical Effects in Silicon: The Case of Ultrafast Processing

open access: yesAdvanced Physics Research, EarlyView.
The dependence of the input polarization for the nonlinear optical propagation in silicon is investigated theoretically and experimentally. The perturbative regime is examined using pump‐probe shadowgraphy and nonlinear transmission, whereas the case of permanent laser‐induced modifications is addressed using a combination of Raman micro‐spectroscopy ...

Controllability and Observability Conditions for Impulsive DAEs on Time Scales

open access: yesAsian Journal of Control, EarlyView.
ABSTRACT This paper establishes criteria for controllability and observability in a class of linear time‐invariant impulsive differential‐algebraic equations (DAEs) defined on a time scale. Controllability is defined as the ability to transfer the system state from any initial condition to any desired state within a finite time interval using an ...

Novel performance analysis techniques with application to the scaling properties of silicon micromotor structures

open access: yes, 2000
An output coefficient extracted from motor design sizing calculations is cast into a form whereby it can be implemented as an actuation independent measure of performance.

Racial gaps without racism: How English universities frame inequality in access and participation plans

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Racial inequalities are pervasive in higher education despite concerted efforts to redress issues of access, progression and continuation. Little attention has been paid to how universities themselves construct race within their policy texts.

Innovation‐Led Sustainability in the Agri‐Food Sector: Evidence From the Global Food and Beverage Industry

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The agri‐food sector is vital to economic development, but it exerts significant environmental and social pressures. This study draws on the natural resource‐based view. It investigates the strategic sustainability‐performance nexus in the global food and beverage industry using a longitudinal dataset (2013–2023) of 633 firms across the EU ...

Locked in Transition: Examining the Role of Paradoxical Tensions in the Transition From Industrial Cluster to Eco‐Clusters

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Industrial clusters are central to the circular economy transition, yet how they develop into eco‐clusters and the paradoxical tensions this transformation fuels remain underexplored. Drawing on 48 in‐depth interviews and secondary data from a Turkish textile‐recycling cluster, we develop an empirically grounded model of eco‐cluster transition
