The Association of Upper Airway Anatomy and Hypoglossal Nerve Stimulation Response in OSA

open access: yesThe Laryngoscope, EarlyView.
CT‐derived measurements of tongue and craniofacial anatomy were evaluated in adults undergoing hypoglossal nerve stimulation for obstructive sleep apnea. Relative tongue volume was not significantly associated with treatment response. Exploratory analyses suggest that other anatomic features such as hyoid positions or transverse maxillary dimensions ...

Shallow grooves in journal improve air bearing performance [PDF]

open access: yes, 1968
Bearing designs, which shape the surface to create artificial fluid-film wedges in the absence of any applied radial load, generate radial restoring forces to keep journals from whirling.

Hygrothermal Aging and Decoupled Axial‐Radial Compressive Failure Mechanisms in Glass Fiber Reinforced Epoxy Filament‐Wound Composite Tubes

open access: yesPolymer Composites, EarlyView.
Composite cylinder under axial and radial compression. ABSTRACT This study examines the hygrothermal degradation of filament‐wound glass fiber‐reinforced epoxy composite tubes designed for application as liners in oil and gas systems, focusing on their response under axial or radial compression.

Cryostratigraphy of Rhythmic Segregated Ice in Colluvium and Implications for Permafrost Slope Stability

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The amount and stratigraphic setting of ground ice in permafrost slopes is a key control on the style and magnitude of permafrost mass wasting. Understanding the spatial and stratigraphic variations in ground ice distribution on permafrost slopes is therefore a fundamental property in assessing the stability of permafrost hillslopes.

Comparison of two numerical weather prediction models in simulating south foehn in the Alpine Rhine Valley

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
ICON outperforms COSMO in simulating a south foehn event in the Alpine Rhine Valley, with improved accuracy in temperature, wind speed, and foehn timing. This enhanced performance likely results from a more accurate representation of surface energy balance and gravity wave pattern on the lee side of the mountain.
