World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Background Chronic rhinosinusitis (CRS) and nasal polyps (NP) are chronic inflammatory conditions with unsatisfactory treatment outcomes due to frequent recurrence of refractory disease. Identifying new therapeutic targets is essential. Methods We conducted a proteome‐wide Mendelian randomization (MR) analysis by integrating genome‐wide ...

Journal of the Royal Anthropological Institute, EarlyView.Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

Index Insurance and Food Security Among Smallholder Farmers in Southern Mali
Journal of Agricultural Economics, EarlyView.ABSTRACT Climate extremes increasingly threaten food security in low‐ and middle‐income countries, where vulnerable smallholder farmers often lack access to risk mitigation tools. Although index‐based insurance has been promoted as a promising adaptation measure to climate shocks, evidence on its welfare effects, especially on food security, remains ...

Sparse Spherical Harmonic Component Selection for Gravity Field Modeling
Remote SensingGravity field modeling with spherical harmonics is a fundamental task in physical geodesy. In conventional solutions, all spherical harmonic (SH) components below a prescribed maximum degree and order are typically retained, even though some components ...

Integrative Zoology, EarlyView.A quantum‐enhanced weighted gene co‐expression network analysis framework integrating quantum amplitude amplification is developed to overcome sample size constraints in zoological genomics. This noise‐tolerant analytical strategy enables robust network reconstruction for non‐model species with limited biological replicates.

A comparative study of the Lasso-type and heuristic model selection methods [PDF]
This study presents a first comparative analysis of Lasso-type (Lasso, adaptive Lasso, elastic net) and heuristic subset selection methods. Although the Lasso has shown success in many situations, it has some limitations.

Bayesian group LASSO for high-dimensional stochastic frontier analysis
Statistical Theory and Related FieldsThis study develops an innovative Bayesian stochastic frontier model that addresses two critical limitations in efficiency analysis: the curse of dimensionality in high-dimensional production environments and the failure to respect natural groupings ...
