From Nature to Supply Chain: Exploring Biomimicry‐Based Pathways to Sustainability and Competitive Advantage

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Inspired by insights gleaned from biomimicry theory, this paper addresses the persistent lack of theoretically grounded research in sustainable supply chain management (SSCM) and examines how nature‐inspired biomimicry principles could enhance various dimensions of its competitiveness. This study's theoretical contribution lies in its proposal

A Passive Tracking System Based on Geometric Constraints in Adaptive Wireless Sensor Networks

open access: yesSensors, 2018
Target tracking technologies in wireless sensor network (WSNs) environments fall into two categories: active and passive schemes. Unlike with the active positioning schemes, in which the targets are required to hold cooperative devices, the research on ...

Stable, Reusable Copper‐Bispidine Catalysts on Agarose With Diffusion‐Limited Turnover: When Immobilization is not Covalent

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Epoxy‐activated agarose beads as support for copper(II)‐bispidine complexes provide reusable heterogeneous catalysts for styrene aziridination with negligible copper leaching. Immobilization occurs largely through noncovalent interactions. Catalyst loading strongly governs performance by balancing active‐site density, accessibility, and mass transport.

Reflex seizures and epilepsy surgery: A network approach case‐based exploration

open access: yesEpileptic Disorders, EarlyView.
Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.
