Octonionic isometric isomorphisms and partial isometries

open access: yesForum Mathematicum
Abstract Very recently, two new notions of para-linear mappings and weak associative orthonormal bases were introduced in octonionic functional analysis, which have been proved to be powerful in formulating the basic theory, such as the Riesz representation theorem and the Parseval theorem.

Mini‐Open Short Superficial and Deep Medial Collateral Ligament Reconstruction of the Knee With Adjustable System

open access: yesArthroscopy Techniques, EarlyView.
Abstract Successful medial collateral ligament (MCL) reconstruction depends on multiple anatomical and biomechanical factors. Various techniques have been described, ranging from isolated superficial MCL reconstructions to complex combined medial reconstructions.

Efficient Computation of Isometry-Invariant Distances between Surfaces

open access: yes, 2008
We present an efficient computational framework for isometry-invariant comparison of smooth surfaces. We formulate the Gromov-Hausdorff distance as a multidimensional scaling (MDS)-like continuous optimization problem.

On completeness in strong partial b-metric spaces, strong b-metric spaces and the 0-Cauchy completions.

open access: yes, 2019
The purpose of this paper is to introduce a new notion of a strong partial b-metric space, discuss the notions of completeness via variants of Cauchy sequences and provide a 0-Cauchy completion result for the spaces.

All‐Inside Primary Anterior Cruciate Ligament Reconstruction Using a Combined Polyester Synthetic Graft and Gracilis Tendon Autograft: Modified Technique of a Hybrid 4 × 2 Graft Preparation

open access: yesArthroscopy Techniques, EarlyView.
Abstract Anterior cruciate ligament reconstruction is a frequently performed procedure in arthroscopic surgery, with rising rates paralleling the incidence of anterior cruciate ligament ruptures worldwide. Synthetic grafts, especially hybrid constructs combining artificial devices with autologous tissue, offer biomechanical advantages and potential ...

An Isometry-Invariant Spectral Approach for Macro-Molecular Docking

open access: yes, 2013
Proteins and the formation of large protein complexes are essential parts of living organisms. Proteins are present in all aspects of life processes, performing a multitude of various functions ranging from being structural components of cells, to ...

Allograft Medial Patellofemoral Ligament Reconstruction Using Patellar Suture Anchors and Stepwise Medial Imbrication

open access: yesArthroscopy Techniques, EarlyView.
Abstract Patellar instability commonly affects adolescents and young athletes and is associated with injury to the medial patellofemoral ligament (MPFL). MPFL reconstruction is a well‐established treatment for recurrent instability; however, complications related to graft tensioning, fixation, and incomplete restoration of medial soft‐tissue restraints

Partial Orders on Partial Isometries

open access: yes, 2015
This paper studies three natural pre-orders of increasing generality on the set of all completely non-unitary partial isometries with equal defect indices.

Anterior Cruciate Ligament Reconstruction Using a Hollow Ligament Advanced Reinforcement System Semitendinosus Autograft Combined With Anterolateral Complex Augmentation Using Gracilis

open access: yesArthroscopy Techniques, EarlyView.
Abstract This technical note describes an alternative surgical technique for anterior cruciate ligament (ACL) reconstruction combined with anterolateral complex (ALC) augmentation. The procedure uses a hollow ligament advanced reinforcement system (LARS), along with semitendinosus and gracilis tendons as grafts.

KARAKTERISTIK OPERATOR HIPONORMAL-p PADA RUANG HILBERT

open access: yes, 2014
This article discusses the definition and properties of p-hiponormal operators for p>0. To investigate the properties of p-hiponormal operators, the concept of positive operators, partial isometry operators, decomposition of operators, and existence ...
