Hyperspectral Image Deconvolution with a Spectral-Spatial Total Variation Regularization

open access: yesCanadian Journal of Remote Sensing, 2017
Hyperspectral images are often unavoidably degraded by blur and noise in the acquisition process, which influences subsequent image processing and analysis.

An ${\ell}_{0}$ -Norm Minimization for Energy-Efficient Timetabling in Subway Systems

open access: yesIEEE Access, 2019
In this paper, a sparse optimization model with ℓ0-norm and the squared ℓ2-norm as the objective function is proposed for energy-efficient timetabling in subway systems by means of improving the regenerative braking energy utilization ...

The Application of Radiofrequency Waves in Supportive Treatment of Temporomandibular Disorders

open access: yesPain Research and Management, 2020
In recent years, the number of patients applying for prosthetic treatment due to temporomandibular joint disorders (TMD) has been increasing. The main methods for treating disorders are the use of occlusal splints and physiotherapeutic rehabilitation as ...

Stability and conservation properties of transient field simulations using FIT [PDF]

open access: yesAdvances in Radio Science, 2003
Time domain simulations for high-frequency applications are widely dominated by the leapfrog timeintegration scheme. Especially in combination with the spatial discretization approach of the Finite Integration Technique (FIT) it leads to a highly ...

An Adaptive Primal-Dual Framework for Nonsmooth Convex Minimization

open access: yes, 2018
We propose a new self-adaptive, double-loop smoothing algorithm to solve composite, nonsmooth, and constrained convex optimization problems. Our algorithm is based on Nesterov's smoothing technique via general Bregman distance functions.

Interplay of Strain Relaxation and Chemically Induced Diffusion Barriers: Nanostructure Formation in 2D Alloys [PDF]

open access: yes, 2004
We study the formation of nanostructures with alternating stripes composed of bulk-immiscible adsorbates during submonolayer heteroepitaxy. We evaluate the influence of two mechanisms considered in the literature: (i) strain relaxation by alternating ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...
