Fixation and escape times in stochastic game learning

open access: yes, 2011
Evolutionary dynamics in finite populations is known to fixate eventually in the absence of mutation. We here show that a similar phenomenon can be found in stochastic game dynamical batch learning, and investigate fixation in learning processes in a ...

Association of Corticospinal Tract Asymmetry With Ambulatory Ability After Intracerebral Hemorrhage

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Ambulatory ability after intracerebral hemorrhage (ICH) is important to patients. We tested whether asymmetry between ipsi‐ and contra‐lesional corticospinal tracts (CSTs) assessed by diffusion tensor imaging (DTI) is associated with post‐ICH ambulation.

GIS-class systems of spatial information as the base for creating strategic acoustic maps of urban areas

open access: yesArchives of Acoustics, 2014
The subject of this paper is an issue of strategic acoustic map creation in cities in accordance with the, so called, EU Noise Directive (END 2002/49) and Polish law related to this directive (act “Environment Protection Law”). The authors of the paper

Predicting Epileptogenic Tubers in Patients With Tuberous Sclerosis Complex Using a Fusion Model Integrating Lesion Network Mapping and Machine Learning

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Accurate localization of epileptogenic tubers (ETs) in patients with tuberous sclerosis complex (TSC) is essential but challenging, as these tubers lack distinct pathological or genetic markers to differentiate them from other cortical tubers.

Evaluation of Strategic Noise Maps Arising from Urban Traffic

open access: yesDoğal Afetler ve Çevre Dergisi, 2020
Environmental noise from traffic, industry and entertainment in cities has been one of the important environmental problems. In developed countries, noise from highways, airways and railways are the second major health problem. Traffic noise has negative effects on human health. The traffic noise exposes are occurring in the high populated living areas.

Strategic environmental noise mapping: Methodological issues concerning the implementation of the EU Environmental Noise Directive and their policy implications

open access: yesEnvironment International, 2010
This paper explores methodological issues and policy implications concerning the implementation of the EU Environmental Noise Directive (END) across Member States. Methodologically, the paper focuses on two key thematic issues relevant to the Directive: (1) calculation methods and (2) mapping methods.

Clustering Algorithm Reveals Dopamine‐Motor Mismatch in Cognitively Preserved Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore the relationship between dopaminergic denervation and motor impairment in two de novo Parkinson's disease (PD) cohorts. Methods n = 249 PD patients from Parkinson's Progression Markers Initiative (PPMI) and n = 84 from an external clinical cohort.

Monitoring the reaction and response of people to urban noise

open access: yesArchives of Acoustics, 2013
An important aspect in assessing noise in urban agglomerations is the subjective one, which takes into account the sensitivity and specific reactions of residents to the noise in their living environment.
