C*-algebras generated by semigroups of partial isometries [PDF]
, 2017 This thesis examines the C*-algebras associated to semigroups of partial isometries. There are many interesting examples of C*-algebras generated by families of partial isometries, for example the C*-algebras associated to directed graphs and the C ...

The Anatomical Record, EarlyView.Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.

Trace Formula for Partial Isometry Case
Tokyo Journal of Mathematics, 2009 Let \(L(H)\) be the algebra of all bounded linear operators on a Hilbert space. Let \(T\in L(H)\) and \(T= U(T)\) be the polar decomposition of \(T\). An operator \(T= U(T)\) is said to be semi-hyponormal if \(|T|\geq |T^*|\). In this paper, the authors prove a trace formula for the polar decomposition of a semi-hyponormal operator \(T= U(T)\) with ...

Integrable system on partial isometries: a finite dimensional picture
, 2023 The aim of the paper is to present the integrable systems on partial isometries which are related to the restricted Grassmannian in finite dimensional context.

The Anatomical Record, EarlyView.We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

The Anatomical Record, EarlyView.Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Descriptions of partial isometries on Hilbert C∗-modules
, 2009 Partial isometries and Moore–Penrose inverses of bounded adjointable operators on Hilbert C∗-modules are investigated. It is shown that a contraction between Hilbert C∗-modules is a partial isometry if and only if it possesses a contractive Moore–Penrose

The Anatomical Record, EarlyView.Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

The Anatomical Record, EarlyView.A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...
