2-isometric operators

Glasnik matematički, 2002
An operator T on a complex Hilbert space is called a 2-isometry if T*2 T2 - 2T* T + I = 0. Our underlying purpose in this article is to investigate some algebraic and spectral properties of 2-isometries.

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs

The Anatomical Record, EarlyView.
Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

The Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

The Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

ISOMETRIC ACTIONS ARE QUASIDIAGONAL

Rocky Mountain Journal of Mathematics
We show every isometric action is quasidiagonal in a strong sense. This shows that reduced crossed products by such actions are quasidiagonal or MF whenever the reduced algebra of the acting group is quasidiagonal or MF.

Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Editorial Commentary: Focus on Quadrupled Grafts With a Thick Anteromedial Bundle in Double‐Bundle Anterior Cruciate Ligament Reconstruction Using Hamstring Tendon Autografts to Improve Graft Survival: Could We Define a Target Graft Diameter?

Arthroscopy, EarlyView.
Abstract The aim of double‐bundle anterior cruciate ligament reconstructions (DB ACLRs) is the reconstruction of anteromedial and posterolateral bundles of the ACL in order to achieve better rotational stability and improved functional results compared with single‐bundle ACLR techniques. Several studies described a considerable failure rate of DB ACLRs.

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

Archaeological 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.

Most Upper Extremity Injuries in Elite Summer League Baseball Players Occur From Overuse, Affect the Shoulder, and Result in Missed Playing Time

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To characterize the epidemiology of upper extremity injuries among elite college baseball players in 1 league over 5 seasons. Methods Deidentified arm injury reports were recorded from the 2018, 2019, 2021, 2022, and 2023 Cape Cod Baseball League (CCBL) seasons.
