Networks, Volume 87, Issue 2, Page 111-130, March 2026.ABSTRACT This work considers branch‐price‐and‐cut algorithms for variants of the vehicle‐routing problem in which subset‐row inequalities (SRIs) are used to strengthen the linear relaxation. SRIs often help to substantially reduce the size of the branch‐and‐bound search tree.

Minimum Makespan Multi-vehicle Dial-a-Ride * [PDF]
, 2020 Dial-a-Ride problems consist of a set V of n vertices in a metric space (denoting travel time between vertices) and a set of m objects represented as source-destination pairs {( , where each object requires to be moved from its source to destination ...

Journal of Neuropsychology, Volume 20, Issue 1, Page 284-290, March 2026.Abstract We describe a peculiar contralesional drawing disorder in three patients affected by focal brain lesions, who did not show signs of unilateral neglect at standard clinical assessment, including the star cancellation test. This picture, that could be termed selective constructional hemi‐apraxia (CHA), could follow both right and left‐hemisphere

Mercy Consent and Contained Resistance: Grievance Systems in Chinese Food‐Delivery Platforms
New Technology, Work and Employment, Volume 41, Issue 1, Page 100-115, March 2026.ABSTRACT Based on a multi‐methods qualitative study, this article investigates how in‐platform grievance systems operate in the Chinese food‐delivery platform work. Drawing on labour process theory, we examine the role of in‐platform grievance systems in shaping the dynamic interplay between control, consent, and resistance. Our findings reveal that in‐

Chemistry &Biodiversity, Volume 23, Issue 1, January 2026.ABSTRACT The fungus Talaromyces fuscoviridis was isolated from soil collected in a copper‐mine tailings basin in Pará State, Brazil, an extreme environment that can induce the production of bioactive secondary metabolites. Extracts and fractions obtained after cultivation were analyzed by liquid chromatography coupled to high‐resolution mass ...

Optimizing Patient Transport under Infection Control Constraints: A Milp-Based Dial-a-Ride Approach
CommunicationsWith aging populations and rising healthcare demands, efficient patient transportation has become a critical challenge, particularly in the context of infection control. In this paper is presented an extended mixed-integer linear programming (MILP) model

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This research presents a robust protection coordination strategy using dual‐setting directional overcurrent relays (DS‐DOCRs) and a novel optimisation approach to address challenges in adaptive protection. A modified objective function, incorporating primary and backup relay operating times along with coordination time intervals (CTIs), is designed to ...
