Detecting single-trial EEG evoked potential using a wavelet domain linear mixed model: application to error potentials classification

open access: yes, 2015
Objective. The main goal of this work is to develop a model for multi-sensor signals such as MEG or EEG signals, that accounts for the inter-trial variability, suitable for corresponding binary classification problems. An important constraint is that the

Secondary Analysis of Database-Stored Qualitative Data: QUESSY as Interface Between QDA and RDBMS Systems

open access: yesForum: Qualitative Social Research, 2005
Data bases or relational data base management systems (RDBMS) offer advantages over the common saving as data files for the storage of qualitative data in secondary analysis archives and larger research projects.

Detection of Eye Occurrence in Sequential Satellite Infrared Imagery and Its Application to Improve Deep Learning‐Based Tropical Cyclone Intensity Estimation

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Tropical cyclone (TC) intensity estimation remains a critical yet challenging task, especially for intense storms that are often underestimated by both conventional and deep learning satellite‐based methods. Among various structural features, eye formation is the most distinct transformation during TC development and is closely linked to rapid

A Practical Quality Control Method for Saponins Without UV Absorption by UPLC-QDA

open access: yesFrontiers in Pharmacology, 2018
Saponins are a class of important active ingredients. Analysis of saponin-containing herbal medicines is a major challenge for the quality control of medicinal herbs in companies.

QDA: A Query-Driven Approach to Entity Resolution

open access: yesIEEE Transactions on Knowledge and Data Engineering, 2017
This paper addresses the problem of query-aware data cleaning in the context of a user query. In particular, we develop a novel Query-Driven Approach ( ${\tt QDA}$ ) that systematically exploits the semantics of the predicates in ${\tt SQL}$ -like selection queries to reduce the data cleaning overhead. The objective of ${\tt QDA}$

Procedural separation of appetitive and consummatory behaviors in operant ethanol self‐administration: A review and open‐source analytical framework

open access: yesAlcohol, Clinical and Experimental Research, Volume 50, Issue 2, February 2026.
This review highlights the biphasic sipper model pioneered by Dr. Hank Samson's laboratory, which separates appetitive and consummatory behaviors in rodent ethanol self‐administration. Over two decades of research using this paradigm reveals that alcohol‐directed behaviors are dynamic, shaped by internal states, cues, and experience.

Bipedalism or bipedalisms: The os coxae of StW 573

open access: yesJournal of Anatomy, Volume 248, Issue 2, Page 163-183, February 2026.
There has been a long debate about the possibility of multiple contemporaneous species of Australopithecus in both eastern and southern Africa, potentially exhibiting different forms of bipedal locomotion. Here, we describe the previously unreported morphology of the os coxae in the 3.67 Ma Australopithecus prometheus StW 573 from Sterkfontein Member 2

Effects of Disorder on Electron Transport in Arrays of Quantum Dots [PDF]

open access: yes, 2005
We investigate the zero-temperature transport of electrons in a model of quantum dot arrays with a disordered background potential. One effect of the disorder is that conduction through the array is possible only for voltages across the array that exceed

T-systems, Y-systems, and cluster algebras: Tamely laced case

open access: yes, 2010
The T-systems and Y-systems are classes of algebraic relations originally associated with quantum affine algebras and Yangians. Recently they were generalized to quantum affinizations of quantum Kac-Moody algebras associated with a wide class of ...

Computer-Aided Qualitative Data Analysis with Word

open access: yesForum: Qualitative Social Research, 2002
Despite some fragmentary references in the literature about qualitative methods, it is fairly unknown that Word can be successfully used for computer-aided Qualitative Data Analyses (QDA).
