DeepZoo: A cost‐effective and modular sampler for ecological studies in the deep ocean

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Understanding the structure and dynamics of deep‐ocean communities requires effective sampling of pelagic organisms in near‐bottom waters. These dispersive organisms contribute to biodiversity, connectivity and ecosystem recovery. Yet, current sampling methods remain constrained by size, cost, and depth, leaving key questions unanswered in ...

Surgical Management of Non‐Allergic Rhinitis—An EAACI Task Force Position Paper

open access: yesAllergy, EarlyView.
ABSTRACT Non‐allergic rhinitis is a frequent yet underdiagnosed cause of chronic nasal symptoms, including nasal congestion, rhinorrhoea, and upper airway hyperreactivity. Its pathophysiology involves neurogenic dysregulation, leading to excessive mucus production and vasodilation.

Vision‐related quality of life following trabeculectomy versus Baerveldt glaucoma implant: Five‐year results from a randomized clinical trial

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To assess the vision‐related quality of life (VRQoL) in glaucoma patients over 5 years after primary Baerveldt glaucoma implant (BGI) or trabeculectomy (TE) using a secondary analysis of a randomized clinical trial. Methods Patients were randomized to undergo TE or receive a BGI.

A Comprehensive Comparative Analysis of Sequence‐Based Deep Learning Models for Single‐Cell Genomics

open access: yesCell Proliferation, EarlyView.
To streamline the application of sequence‐based DL methods in single‐cell genomics, we established a two‐layer CNN as our baseline model. We focus our benchmark on how data characteristics, hyperparameter optimization, and advanced model architectures impact performance across sequence‐to‐expression and sequence‐to‐regulation tasks.
