Revisiting the learning curve (once again)

open access: yesFrontiers in Psychology, 2013
The vast majority of published work in the field of associative learning seeks to test the adequacy of various theoretical accounts of the learning process using average data.

Discrete-Time Semi-Markov Random Evolutions in Asymptotic Reduced Random Media with Applications

open access: yesMathematics, 2020
This paper deals with discrete-time semi-Markov random evolutions (DTSMRE) in reduced random media. The reduction can be done for ergodic and non ergodic media.

Implementation of real-time digital filter for the R wave detection

open access: yesTecnoLógicas, 2015
Quantification of the instantaneous heart rate is based on the detection of the R wave of the electrocardiographic signal. This process requires the implementation of strategies for real-time filtering for the time of occurrence of each R wave.

Averaging in LTL [PDF]

open access: yes, 2014
For the accurate analysis of computerized systems, powerful quantitative formalisms have been designed, together with efficient verification algorithms. However, verification has mostly remained boolean--either a property is true, or it is false. We believe that this is too crude in a context where quantitative information and constraints are crucial ...

A review of numerical asymptotic averaging for weakly nonlinear hyperbolic waves

open access: yesMathematical Modelling and Analysis, 2004
We present an overview of averaging method for solving weakly nonlinear hyperbolic systems. An asymptotic solution is constructed, which is uniformly valid in the “large” domain of variables t + |x| ∼ O(ϵ –1).

Integration of visual motion and orientation signals in dyslexic children: an equivalent noise approach

open access: yesRoyal Society Open Science, 2022
Dyslexic individuals have been reported to have reduced global motion sensitivity, which could be attributed to various causes including atypical magnocellular or dorsal stream function, impaired spatial integration, increased internal noise and/or ...

Use of zero-frequency resonator for automatically detecting systolic peaks of photoplethysmogram signal

open access: yesHealthcare Technology Letters, 2019
This work investigates the application of zero-frequency resonator (ZFR) for detecting systolic peaks of photoplethysmogram (PPG) signals. Based on the authors’ studies, they propose an automated noise-robust method, which consists of the central ...

Word-embedding Based Text Vectorization Using Clustering

open access: yesМоделирование и анализ информационных систем, 2021
It is known that in the tasks of natural language processing, the representation of texts by vectors of fixed length using word-embedding models makes sense in cases where the vectorized texts are short.The longer the texts being compared, the worse the ...

Controlled Discrete-Time Semi-Markov Random Evolutions and Their Applications

open access: yesMathematics, 2021
In this paper, we introduced controlled discrete-time semi-Markov random evolutions. These processes are random evolutions of discrete-time semi-Markov processes where we consider a control. applied to the values of random evolution.

A complete data processing workflow for CryoET and subtomogram averaging [PDF]

open access: yesNature Methods, 2019
Electron cryotomography is currently the only method capable of visualizing cells in three dimensions at nanometer resolutions. While modern instruments produce massive amounts of tomography data containing extremely rich structural information, data ...
