Collapsing of dimensionality

open access: yesCoRR, 2017
We analyze a new approach to Machine Learning coming from a modification of classical regularization networks by casting the process in the time dimension, leading to a sort of collapse of dimensionality in the problem of learning the model parameters. This approach allows the definition of a online learning algorithm that progressively accumulates the

Thoracoabdominal Asynchrony in Healthy Children

open access: yesJournal of Sleep Research, Volume 35, Issue 5, October 2026.
ABSTRACT Measuring asynchrony between the thorax and abdomen during sleep provides information about inspiratory effort and upper airway obstruction in children, aiding in the diagnosis of obstructive sleep apnea (OSA). This study aimed to define a normative range for thoracoabdominal asynchrony (TAA) in healthy children by studying polysomnographies ...

Mechanical parameters determining pharyngeal collapsibility in patients with sleep apnea

open access: yes, 2010
The relative impact of mechanical factors on pharyngeal patency in patients with obstructive sleep apnea is poorly understood. The present study was designed to evaluate parameters of the “tube law” on pharyngeal pressure-flow relationships and ...

Inferior vena cava collapsibility loses correlation with internal jugular vein collapsibility during increased thoracic or intra-abdominal pressure

open access: yes, 2015
PURPOSE: Point-of-care ultrasound evaluates inferior vena cava (IVC) and internal jugular vein (IJV) measurements to estimate intravascular volume status.

Three‐Dimensional Assessment of Upper Airway Morphology and Sleep‐Disordered Breathing Risk in Unilateral Craniofacial Microsomia: A Pilot Study

open access: yesOrthodontics &Craniofacial Research, Volume 29, Issue 5, Page 926-936, October 2026.
ABSTRACT Objective Unilateral craniofacial microsomia (UCM) presents varying unilateral deficiencies of the temporomandibular joint, mandibular ramus, masticatory muscles, and adjacent soft tissues and ear. Reduced mandibular and maxillary dimensions may decrease upper airway volume and may increase the risk of sleep‐disordered breathing (SDB).

Avoiding Femoral Tunnel Convergence and Graft Damage While Performing Anterior Cruciate Ligament Reconstruction With Lateral Extra‐articular Tenodesis

open access: yesArthroscopy Techniques, Volume 15, Issue 9, September 2026.
Abstract Lateral extra‐articular tenodesis (LET) procedures have become increasingly popular in recent years as adjuncts to anterior cruciate ligament (ACL) reconstruction. One potential complication of combining LET with ACL reconstruction is tunnel convergence, which can lead to inadvertent loss of femoral ACL graft fixation.

Collapsibility and Wettability of Hydrothermally Treated Wood [PDF]

open access: yes, 2012
Study on collapsibility of oriental beech (Fagus orientalis) and paulownia (Paulownia fortune) woods due to their hydrothermal modification as well as the wettability and the water absorption were the main concerns of this research work.

Pleistocene Legacies in the Contemporary Population Genetic Structure of an Acid‐Specialised Crayfish, the Threatened Sand Yabby Cherax robustus

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study describes the contemporary genetic structure of a vulnerable short‐range endemic crayfish which is restricted to the heavily fragmented heathland‐peatland complexes of southeast Queensland across a range of approximately 200 km2. Using high‐resolution genome‐wide SNP sequencing, we estimate that population divergence in this species ...

Assessment of Hyporheic Macroinvertebrate Biodiversity Within Gravel Bars Before and After Flooding: Comparison of Morphology, Bulk‐Sample, and eDNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 5, September‐October 2026.
eDNA metabarcoding is generally consistent with morphology and bulk‐sample metabarcoding in revealing changes in hyporheic macroinvertebrate biodiversity influenced by flood and lateral locations of hyporheic zones.
