Spectroscopic Imaging of Cutaneous Squamous Cell Carcinoma Based on Acousto-Optic Filtering

, 2020
Noncollinear acousto-optic tunable filter (AOTF) based on TeO2 is a type of good light splitting device with the electric tuning. Because of its advantages of compact size, high stability, fast tuning, and being easy to carry out, it has high practical ...

A comparative study of two models for the seismic analysis of buildings

Ingeniería e Investigación, 2012
This paper presents a model for the seismic analysis of buildings, taking two lumped masses at each level in a structure’s free nodes and comparing them to the traditional model which considers lumped masses per level, i.e., a mass for each floor of the ...

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Demo 06-01 Angular Acceleration Machine

, 2001
This device illustrates the application of the rotational analog of Newton's second law, t = I a. Two weights can be positioned symmetrically along an arm that rotates in a vertical plane around its center, varying the moment of inertia of the rotating

Some Experiences of Improving the Speed of Numerical Navier-Stokes Solver Using CUDA

Journal of Algorithms & Computational Technology, 2014
In this paper, the Graphics Processor Unit (GPU) is adopted to accelerate the codes of solving incompressible Navier-Stokes equations with two fully different numerical schemes: spectral method and finite difference method. Compared with the codes on CPU,

Cognitive and Neuroimaging Divergence Between Juvenile and Adult FUS Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive motor neuron degeneration. Fused in sarcoma (FUS)‐associated juvenile ALS (jALS) represents a distinct and aggressive subgroup with rapid deterioration and poor prognosis.

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.

Global Rather Than Vertical‐Selective Saccadic Abnormalities in Progressive Supranuclear Palsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To test whether vertical saccades are preferentially affected in Progressive Supranuclear Palsy (PSP). Methods PSP patients (n = 24) were compared to age‐matched controls (n = 94) and two degenerative groups (Alzheimer's disease, n = 20; Lewy body disease, n = 50).

Study on Recognition of Marine Microplastics Using Raman Spectra Combined With MTF and CNN

In recent years, seawater pollution caused by microplastic waste has caught more and more attention. Raman spectroscopy, a non-destructive detection technique, has representative spectral characteristic peaks, making it easier to identify unknown samples.
