Topology of matching complexes of complete graphs via discrete Morse theory [PDF]

Discrete Mathematics & Theoretical Computer Science
Bouc (1992) first studied the topological properties of $M_n$, the matching complex of the complete graph of order $n$, in connection with Brown complexes and Quillen complexes. Bj\"{o}rner et al. (1994) showed that $M_n$ is homotopically $(\nu_n-1)$

Operations Research‐Based Formalisation and Design of Sustainable Reverse Logistics for E‐Waste Supply Chains

Business Strategy and the Environment, EarlyView.
ABSTRACT This study demonstrates how a profitable, lean, and environmentally responsible e‐waste reverse logistics system can be designed using integrated Operations Research (OR) techniques. Addressing the growing urgency of responsible consumption (UN SDG 12) and the projected rise of the e‐waste sector to USD 137.60 billion by 2029, the research ...

H(div)-conforming finite element tensors with constraints

Results in Applied Mathematics
A unified construction of H(div)-conforming finite element tensors, including vector element, symmetric matrix element, traceless matrix element, and, in general, tensors with linear constraints, is developed in this work.

Upper bound limit analysis of coral reef limestone cavern roof stability incorporating a tension‐shear failure mechanism with tensile‐strength cut‐off

Deep Underground Science and Engineering, EarlyView.
For the roof of coral reef limestone caverns, a novel tension‐shear composite failure mechanism was developed. The most critical tensile crack model was identified using a hybrid optimization algorithm, and the stability of the cavern roof was analyzed accordingly.

Psychopathological and Temperamental Stratification of Eating Disorders With Clustering: From Diagnosis to Phenotypic Diversity

European Eating Disorders Review, EarlyView.
ABSTRACT Objective Eating disorders are highly heterogeneous, challenging diagnostic classification and treatment personalisation. This study aimed to identify data‐driven phenotypes of anorexia nervosa and bulimia nervosa and examine their relationship with DSM‐5 diagnoses and short‐term treatment outcomes. Methods We analysed 809 female patients with

Bayesian Multivariate Two‐Stage Volatility‐Return Models (MTS‐VR)

Journal of Forecasting, EarlyView.
ABSTRACT This paper develops a class of models to capture the joint dynamics of asset returns and multivariate volatility. Owing to its two‐stage construction, this class is referred to as the multivariate two‐stage volatility‐return (MTS‐VR) model.

Analysis of individualized brain–gut association networks and transcriptional patterns in major depressive disorder

Interdisciplinary Medicine, EarlyView.
Individualized brain–gut association networks suggest potential neuropathological mechanisms in MDD and MDDSI. Multilevel brain–gut association changes involving HSV‐1 and inflammation may be relevant to MDD, whereas alterations related to insulin metabolism may play a potential role in the neuropathological mechanisms of MDDSI.
