Orthogonal Nonnegative Tucker Decomposition [PDF]

open access: yesSIAM Journal of Scientific Computing, 2021
In this paper, we study the nonnegative tensor data and propose an orthogonal nonnegative Tucker decomposition (ONTD). We discuss some properties of ONTD and develop a convex relaxation algorithm of the augmented Lagrangian function to solve the optimization problem. The convergence of the algorithm is given.

L1-Norm Tucker Tensor Decomposition

open access: yesIEEE Access, 2019
Tucker decomposition is a standard multi-way generalization of Principal-Component Analysis (PCA), appropriate for processing tensor data. Similar to PCA, Tucker decomposition has been shown to be sensitive against faulty data, due to its L2-norm-based ...

The “Inside-Out” Anterior Osteotomy of the Proximal Femur via the Direct Anterior Approach in Revision Hip Arthroplasty

open access: yesArthroplasty Today, 2023
Osteotomy techniques used for wide exposure during femoral component revision include the extended trochanteric osteotomy and its modifications. We describe an anterior proximal femur osteotomy technique starting from the inside of the femoral canal at ...

Synthetic Mesh Reconstruction of Chronic, Native Quadriceps Tendon Disruptions following Failed Primary Repair

open access: yesCase Reports in Orthopedics, 2021
Case. Two patients presented with chronic knee extensor mechanism disruption after failed primary repairs. Both patients had minimal ambulatory knee function prior to surgical intervention and were treated with a synthetic mesh reconstruction of their ...

Optimization landscape of Tucker decomposition [PDF]

open access: yesMathematical Programming, 2020
Tucker decomposition is a popular technique for many data analysis and machine learning applications. Finding a Tucker decomposition is a nonconvex optimization problem. As the scale of the problems increases, local search algorithms such as stochastic gradient descent have become popular in practice.

Physics linkages between arterial stiffness, cerebrovascular flow and cognitive impairment

open access: yesVeins and Lymphatics, 2022
Background. Reduced cerebrovascular flow and localized hypoperfusion have been widely associated with various forms of cognitive impairment. Vascular cognitive impairment has also been associated with arterial stiffening and arteriosclerotic development.

Telomere-mediated Chromosomal Truncation via Agrobacterium tumefaciens or Particle Bombardment to Produce Engineered Minichromosomes in Plants

open access: yesBio-Protocol, 2015
Minichromosomes are small, autonomously functioning chromosomes that exist separately from the normal chromosomal set. Creation of minichromosomes in plants relies on telomere truncation to remove the chromosome arms and the native telomere sequence and ...

Physics Linkages Between Arterial Morphology, Pulse Wave Reflection and Peripheral Flow

open access: yesArtery Research, 2023
Background Previous physics-based analyses of arterial morphology in relation to pulsatile pressure and flow, with pulse wave reflection, focused on the large arteries and required assumptions about the relative thicknesses of arterial walls and the ...

The Impending Crisis

open access: yesJournal of Microbiology & Biology Education, 2010
When you are ill and consult a physician for his or her expertise, many times laboratory testing is part of the clinical workup. This testing is critical to the physician’s ability to diagnose the patient’s condition.

Stress and timing associated with Caenorhabditis elegans immobilization methods

open access: yesHeliyon, 2020
Background: Caenorhabditis elegans is a model organism used to study gene, protein, and cell influence on function and behavior. These studies frequently require C. elegans to be immobilized for imaging or laser ablation experiments.
