Singular Value Decomposition Wavelength-Multiplexing Ghost Imaging

Photonics
To enhance imaging quality, singular value decomposition (SVD) has been applied to single-wavelength ghost imaging (GI) or color GI. In this paper, we extend the application of SVD to wavelength-multiplexing ghost imaging (WMGI) for reducing the ...

Von Economo Neuron Loss in Frontotemporal Dementia: A Meta‐Analysis of Neuropathological Studies

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Von Economo neurons (VENs) have been reported to be vulnerable to neurodegeneration in frontotemporal dementia (FTD), particularly the behavioral variant (bvFTD), but these findings have not been systematically assessed across independent brain banks.

Relationship Between Neurologic Symptoms and Signs and FMR1 Genotype in Premutation Carriers

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Fragile X‐associated Tremor/Ataxia Syndrome (FXTAS) is the most severe late‐onset condition caused by a premutation in the FMR1 gene, characterized by expanded CGG triplet repeats of 55–200. Clinical presentations of FXTAS, including gait ataxia, kinetic tremor, cognitive decline, and rare Parkinsonism, are linked to ...

Imperceptible of Watermarking in Digital Image Based Singular Value Decomposition

Makara Seri Sains, 2006
Watermarking is a commonly used technique to protect digital image from unintended used such as counterfeiting. This paper will address one of the techniques to embed a watermark to digital image which is based on the singular value decomposition.

Singular boundary value problems for quasi-differential equations

International Journal of Mathematics and Mathematical Sciences, 1995
Solutions are obtained of boundary value problems for Lny+f(x,L0y,…,Ln−2y), satisfying L2y(0)=Ln−1y(1)=0, 0≤i≤n−2, where Li, denotes the ith quasiderivative, and where f(x,y1,…,yn−1) has singularities at yi=0, 1≤i≤n−1.

Comparing the Effect of Semi‐Immersive Virtual Reality, Computerized Cognitive Training, and Traditional Rehabilitation on Cognitive Function in Multiple Sclerosis: A Randomized Clinical Trial

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Cognitive impairment is a common non‐motor symptom in Multiple Sclerosis (MS), negatively affecting autonomy and Quality of Life (QoL). Innovative rehabilitation strategies, such as semi‐immersive virtual reality (VR) and computerized cognitive training (CCT), may offer advantages over traditional cognitive rehabilitation (TCR ...

Singular perturbation for nonlinear boundary-value problems

International Journal of Mathematics and Mathematical Sciences, 1979
Asymptotic solutions of a class of nonlinear boundary-value problems are studied. The problem is a model arising in nuclear energy distribution. For large values of the parameter, the differential equations are of the singular-perturbation type and ...

Remarkable Recovery After Delayed High‐Dose Methylprednisolone in a Rare Case of Penetrating Spinal Cord Injury

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Traumatic spinal cord injury (TSCI) caused by sharp‐force penetration is exceptionally rare, and the use of high‐dose methylprednisolone (MP) remains highly controversial, especially beyond the conventional 8‐h treatment window. This case report describes a 30‐year‐old male with acute incomplete TSCI following a knife stab wound to the right ...

Singular value inequalities for generalized anticommutators

Journal of Inequalities and Applications
We shown among other inequalities that if A 1 $A_{1}$ , B 1 $B_{1}$ , X 1 $X_{1}$ , and Y 1 $Y_{1}$ are n × n $n\times n$ complex matrices such that A 1 $A_{1}$ and B 1 $B_{1}$ are positive semidefinite, then s j ( Y 1 A 1 X 1 − X 1 B 1 Y 1 ) ≤ s j ( Z ⊕
