Inter‐Model Feature Fusion for Robust Low‐Resource Speech Recognition

open access: yesApplied AI Letters, Volume 7, Issue 2, June 2026.
Our Self‐Supervised Feature Fusion (SSF‐FT) method enhances low‐resource speech recognition by adaptively combining features from self‐supervised models trained with Contrastive, Predictive, and Reconstruction objectives. This attention‐weighted ensemble delivers robust performance, particularly in acoustically challenging conditions, extending current

The propagation of mountain waves into the stratosphere: Quantitative evaluation of three-dimensional simulations

open access: yes, 2000
On 6 January 1992 measurements of a mountain wave with significant amplitude were taken over the southern tip of Greenland during an ER-2 flight at an altitude of about 20 km.

Shaping research in marine functional connectivity for integrated and effective marine science and management

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1143-1180, June 2026.
ABSTRACT Effective knowledge of ecological connectivity at sea and at the land–sea interface is key to supporting global policy goals to conserve and restore ocean biodiversity and function. However, a persistent lack of commonality in terminology and understanding around the concept of connectivity in marine ecological studies hampers its integration ...

Large-amplitude capillary waves in electrified fluid sheets

open access: yes, 2004
Large-amplitude capillary waves on fluid sheets are computed in the presence of a uniform electric field acting in a direction parallel to the undisturbed configuration. The fluid is taken to be inviscid, incompressible and non-conducting.

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

open access: yesHeat Transfer, Volume 55, Issue 4, Page 2201-2232, June 2026.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Microrobots: Two Decades of Progress

open access: yesSmartBot, Volume 2, Issue 2, June 2026.
Microrobots are governed by counterintuitive viscous‐dominated microscale physics, making traditional large‐scale driving principles unapplicable and restricting their reliable in‐body locomotion implementation. Multiple propulsion schemes and advanced microfabrication techniques have been developed to bypass such physical limitations and enrich ...

A review of the state of art in applying Biot theory to acoustic propagation through the bone [PDF]

open access: yes
Understanding the propagation of acoustic waves through a liquid-perfused porous solid framework such as cancellous bone is an important pre-requisite to improving the diagnosis of osteoporosis by ultrasound.
