Globalization of the partial isometries of metric spaces and local approximation of the group of isometries of Urysohn space

open access: yes, 2008
We prove the equivalence of the two important facts about finite metric spaces and universal Urysohn metric spaces U, namely Theorems A and G: Theorem A (Approximation): The group of isometry ISO(U) contains everywhere dense locally finite subgroup ...

Exploring the cranial morphology and possible convergences of Triassic non‐crocodylomorph pseudosuchians (Archosauria: Pseudosuchia) with other sauropsids through linear morphometrics

open access: yesThe Anatomical Record, EarlyView.
Abstract Triassic pseudosuchians had highly diversified cranial morphologies. These archosaurs occupied diverse ecological roles, ranging from terrestrial predators and herbivores to semiaquatic ambush predators and possible waders. Here, we apply linear cranial morphometrics to assess possible convergences with other sauropsids from the clades ...

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Coherence‐Gated Wrapped‐Phase InSAR With Matrix‐Based Uncertainty Diagnostics for Burial‐Mound Hotspot Ranking (Sicily, Italy)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Burial mounds are key elements of Mediterranean funerary landscapes, but in intensively cultivated coastal plains their low‐relief expression is easily obscured by ploughing, levelling and rapidly changing surface conditions, making single‐date observations unreliable.

Tissue‐Specific and Spatially Dependent Metabolic Signatures Perturbed by Injury in Male and Female Mice

open access: yesArthritis &Rheumatology, EarlyView.
Objective Osteoarthritis, the leading cause of disability worldwide, disproportionately affects women, yet sex remains an overlooked determinant. This disparity stems from sex‐specific differences in injury susceptibility—a major risk factor for disease.

A Low-dimensional Representation for Robust Partial Isometric Correspondences Computation

open access: yes, 2014
Intrinsic shape matching has become the standard approach for pose invariant correspondence estimation among deformable shapes. Most existing approaches assume global consistency.

Arthroscopy‐Assisted Fixation of Combined Coracoid Fracture and Acromioclavicular Dislocation: A Minimalist Approach

open access: yesArthroscopy Techniques, EarlyView.
Abstract Combined acromioclavicular dislocation and coracoid process fracture disrupts the superior shoulder suspensory complex, leading to shoulder instability that often requires surgical intervention. This rare injury, increasingly identified through advanced diagnostics, lacks consensus on the optimal treatment. We describe a minimalist arthroscopy‐

Morfología de las especies de Hyphessobrycon (Characiformes: Characidae), grupo heterorhabdus, en Colombia

open access: yesRevista de Biología Tropical, 2011
El género Hyphessobrycon incluye dieciocho especies reportadas para Colombia de las cuales 13 son miembros del grupo heterorhabdus; con las mismas, se realizó un análisis morfogeométrico por medio del Método de Cerchas (Box Truss) y Láminas Delgadas (TPS)

Dynamic Ultrasound Evaluation Supraspinatus Tendon Injuries Using a Pilates Elastic Band

open access: yesArthroscopy Techniques, EarlyView.
Abstract Supraspinatus tendon tears are a common cause of shoulder pain and dysfunction. Although magnetic resonance imaging and computed tomography arthrography are still considered the gold standard, ultrasound offers a reliable, accessible, and radiation‐free alternative.
