Modelling of noise level in the northern part of Klaipeda city/Triukšmo lygio šiaurinėje Klaipėdos dalyje modeliavimas/Моделирование шумового уровня в северной части города Kлайпеды

Journal of Environmental Engineering and Landscape Management, 2009
Noise is an urgent problem not only in Lithuania but also all over the world. There are no noise‐reducing walls in the northern part of Klaipeda that could be used as reducers of noise spread from streets to the residential territory.

Real‐World Performance of CSF Kappa Free Light Chains in the 2024 McDonald Criteria

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Kappa free light chains (KFLCs) in the cerebrospinal fluid (CSF) have a similar performance to CSF‐restricted oligoclonal bands (OCB) for multiple sclerosis (MS) diagnosis. To help with implementation, we set out to resolve several remaining uncertainties: (1) performance in a real‐world cohort and the 2024 McDonald criteria; (2 ...

Influence of Ambient Noise Source Distributions on Cross-correlation Derived Seismic Waveforms and Dispersion Curve Retrieval

CT Lilun yu yingyong yanjiu
Dense-array observation has become a key method for obtaining high-resolution subsurface structures. However, the spatiotemporal heterogeneity of the noise source distribution significantly reduces the signal-to-noise ratio (SNR) of noise correlation ...

Improvement of BM3D Algorithm and Employment to Satellite and CFA Images Denoising

, 2011
This paper proposes a new procedure in order to improve the performance of block matching and 3-D filtering (BM3D) image denoising algorithm. It is demonstrated that it is possible to achieve a better performance than that of BM3D algorithm in a variety ...

Noise level study and assessment in the southern part of Panevežys

Journal of Environmental Engineering and Landscape Management, 2010
Noise is a relevant problem faced not only by Lithuania but across the world. With motor traffic flow increase, the noise caused by them is also growing and in particular noisy are heavy vehicles and motorcycles.

Brainstem and Cerebellar Volume Loss and Associated Clinical Features in Progressive Supranuclear Palsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Progressive Supranuclear Palsy (PSP) is a neurodegenerative ‘tauopathy’ with predominating pathology in the basal ganglia and midbrain. Caudal tau spread frequently implicates the cerebellum; however, the pattern of atrophy remains equivocal.

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

Annals 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 ...
