Thermally Programmable Two‐Port Non‐Hermitian Acoustic Metastructure for Broadband and Direction‐Dependent Absorption

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
A thermally programmable two‐port non‐Hermitian acoustic metastructure is presented, where temperature acts as a non‐geometric tuning variable. Thermal modulation reconfigures impedance matching and loss‐leakage coupling, enabling exceptional‐point driven, broadband, and direction‐dependent sound absorption without requiring geometric reconfiguration ...

Refining Detection of Subclinical Epileptiform Activity in Alzheimer's Disease: A Case–Control Study and Call for a Consensus

open access: yesAnnals of Neurology, Volume 99, Issue 4, Page 1046-1058, April 2026.
[Color figure can be viewed at www.annalsofneurology.org] Objective Sleep‐predominant network hyperexcitability is increasingly recognized as a potential disease‐accelerating comorbidity in Alzheimer's disease (AD). However, its prevalence and risk‐factors remain debated, largely due to cohort‐specific and methodological differences across studies.

Room Impulse Response Dataset of a Recording Studio with Variable Wall Paneling Measured Using a 32-Channel Spherical Microphone Array and a B-Format Microphone Array

open access: yesApplied Sciences
This paper introduces RSoANU, a dataset of real multichannel room impulse responses (RIRs) obtained in a recording studio. Compared to the current publicly available datasets, RSoANU distinguishes itself by featuring RIRs captured using both a 32-channel

Optimisation of the spatial configuration of microphones for robust virtual sensing in a diffuse sound field

open access: yesActa Acustica
Virtual sensing methods are utilised in active noise control systems where the error sensors cannot be placed at the locations where control is physically required.

Expanding Access to Genome Sequencing: Higher Diagnostic Yield in Self‐Referred Participants From the CincyKidsSeq Study and Implications for Hybrid Models of Genetic Service Delivery

open access: yesClinical Genetics, Volume 109, Issue 4, Page 717-724, April 2026.
Genome sequencing helped find answers for 1 in 5 children with rare conditions in an outpatient study looking at hybrid genetic care delivery. Families who chose testing themselves had the highest diagnostic yield, showing that self‐referral may be a helpful way to improve access to genetic care.

Trophic Diversity in Aquatic Food Webs Along a Tropical Coastal River Continuum in West‐Central Africa

open access: yesFreshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT In the wet Afrotropics, information on trophic diversity and resource use in freshwaters is extremely limited. Here we used stable isotope ratios (δ13C, δ15N) from food webs along the continuum of a coastal river in the Republic of the Congo to examine seasonal and spatial patterns of trophic diversity.

An automated workflow that combines sound‐based bird identification and localization

open access: yesIbis, Volume 168, Issue 2, Page 554-570, April 2026.
Field studies of bird communities typically require the fine‐scale mapping of individuals. Passive acoustic monitoring combined with localization of individuals is a promising approach to gather such data. Various approaches for the identification of species and localization of individuals have been proposed, but there is so far no fully automated ...

A new species of jewel‐babbler (Cinclosomatidae: Ptilorrhoa) from the Southern Fold Mountains of Papua New Guinea

open access: yesIbis, Volume 168, Issue 2, Page 431-450, April 2026.
Based on distinctive morphological and vocal characters we describe a new species of jewel‐babbler (genus Ptilorrhoa) from the forested karst of the Southern Fold Mountains in Papua New Guinea. The description is based on camera trap data and is presented in accordance with ICZN Declaration 45.
