Tighter MIP formulations for the discretised unit commitment problem with min-stop ramping constraints

open access: yesEURO Journal on Computational Optimization, 2017
This paper elaborates compact MIP formulations for a discrete unit commitment problem with minimum stop and ramping constraints. The variables can be defined in two different ways.

Hair fragility (trichorrhexis nodosa) in alopecic Pomeranian dogs

open access: yesVeterinary Dermatology, Volume 36, Issue 1, Page 64-73, February 2025.
Background – Alopecia associated with hair cycle arrest (HCA, Alopecia X) is well‐recognised in Pomeranian dogs. The authors are unaware of reports of hair fragility in affected dogs. Hypothesis/Objectives – Following the observation of frequent hair shaft abnormalities in alopecic Pomeranians, we hypothesised that hair fragility events would be more ...

Matching ontologies with kernel principle component analysis and evolutionary algorithm

open access: yesDemonstratio Mathematica
Ontology serves as a structured knowledge representation that models domain-specific concepts, properties, and relationships. Ontology matching (OM) aims to identify similar entities across distinct ontologies, which is essential for enabling ...

Compact ILP formulations for the routing and wavelength assignment problem in the design of optical transport networks with regenerators

open access: yesEURO Journal on Computational Optimization, 2016
This paper addresses two variants of the routing and wavelength assignment problem arising in the context of optical transport networks. In both variants, we address the case where the physical coverage of the fiber network is such that regenerators, to ...

Efficacy of an oral chew containing fibre and Bacillus velezensis C‐3102 in the management of anal sac impaction in dogs

open access: yesVeterinary Dermatology, Volume 36, Issue 1, Page 74-82, February 2025.
Background — Anal sac impaction is common in dogs and manual expression may be effective, yet recurrence remains a problem. To facilitate physiological emptying of the sacs, it is important to maintain a bulky stool consistency. Objectives — The study evaluated if supplementation with ProGlan, a complementary feed containing Bacillus velezensis C‐3102 ...

A modified RMIL conjugate gradient-based projection algorithm for constrained nonlinear equations: application to image denoising

open access: yesDemonstratio Mathematica
In this paper, a modified Rivaie-Mohd-Ismail-Leong (RMIL) conjugate gradient-based projection algorithm for constrained nonlinear equations is proposed, which integrates projection techniques and line search approaches to enhance solution accuracy and ...

Infant mental health integration into OB care leads to increased connection to services during the perinatal period

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 46, Issue 1, Page 95-111, January 2025.
Abstract We compared referrals and connection to care between perinatal patients: 90 receiving OB/GYN care in clinics with integrated behavioral health consultants with infant mental health specialization (IMH‐BHC), and 68 receiving traditional care, in the United States.

Core group placement: allocation and provisioning of heterogeneous resources

open access: yesEURO Journal on Computational Optimization, 2019
We present a theoretical and empirical study on a recently introduced combinatorial optimization problem, namely core group placement problem. The problem arises from real-world business requirements as part of resource allocation in cloud management. In

Ultraviolet radiation protection factors of livestock shade cloths for free‐range pigs

open access: yesVeterinary Dermatology, Volume 35, Issue 6, Page 641-651, December 2024.
Background – Protection from solar ultraviolet radiation (UVR) is paramount in light‐skinned pig breeds such as Yorkshire or Landrace to avoid sunburn. Objectives – Determination of the UVR exposure of a pig and the sun protection abilities of shade cloths with different shade rates.
