Measuring the Task Induced Oscillatory Brain Activity Using Tensor Decomposition

2019

The characterization of dynamic electrophysiological brain activity, which form and dissolve in order to support ongoing cognitive function, is one of the most important goals in neuroscience. Here, we introduce a method with tensor decomposition for measuring the task-induced oscillations in the human brain using electroencephalography (EEG). The time frequency representation of source-reconstructed singletrail EEG data constructed a third-order tensor with three factors of time ∗ trails, frequency and source points. We then used a non-negative Canonical Polyadic decomposition (NCPD) to identify the temporal, spectral and spatial changes in electrophysiological brain activity. We validate …

Rossiâ - Polʹša: nesovpadenie pamâtej. Lingvističeskij aspekt

2017

„Memory turn” in the humanities allows to approach old problems from a new perspective. The author argues that the sphere of complicated Russian-Polish relations should be presented as a conflict between two distinct collective memories. The author considers “memory” as strictly interconnected with so called “non-memory” (i.e. as set of facts not related to memory or superseded by it). In principle, collective memory / non-memory can be subjected to linguistic analysis because it is verbalized and therefore it has its different verbal exponents. The author refers back to his concept of “mental geography” developed 20 years ago and argues that a multi-stage process of mapping two national me…

Il primo concorso per il Palazzo di Giustizia a Roma del 1884. Ricostruzione critica del progetto di Ernesto Basile

2019

1. Breve descrizione dell’oggetto di studio Il concorso del Palazzo di Giustizia di Roma si svolge in quattro fasi svolte tra il 1884 e il 1887. Il progetto per il primo concorso, del 1884, redatto dall’allora giovanissimo Ernesto Basile (Palermo 1857-1932), rivela una grande perizia progettuale che trasforma il complesso programma funzionale in un austero edificio in stile neofiorentino. I disegni originari dell’opera, non realizzata, conservati presso la Dotazione Basile del Dipartimento di Architettura dell’Università di Palermo, sono stati oggetto di studio propedeutico alle fasi di analisi, interpretazione e ricostruzione congetturale del modello digitale. 2. Stato dell’arte e riferime…

Objectives pursued and achieved Conjectural reconstruction achieved the following results: • formulation of analytical documents which show how the planimetric and altimetric articulation are perfectly consistent with the functional program• definition of the level of uncertainty1. Brief description of the object of study The competition of the Palace of Justice in Rome takes place in four phases between 1884 and 1887. The project for the first competition in 1884 drawn up by the then very young Ernesto Basile (Palermo 1857-1932) reveals a great deal of design expertise that transforms the complex functional program into an austere building in neo-florentine style. The original drawings of the building not realized kept in the Basile Endowment of the Department of Architecture of the University of Palermo have been the subject of preliminary study to the phases of analysis interpretation and conceptual reconstruction of the digital model. 2. State of the art and main bibliographical references The conjectural reconstruction on the basis of drawings and archival documents is a well-established and codified practice thanks to various disciplinary contributions at national and international level.

The (im)possible success of disadvantaged students. Reflections on education, migration and social change

2019

The paper focuses on the ?unexpected pathways? of successful students with an immigrant background: these biographical routes, that seems socially impossible, raise theoretical issues around the individual-society, actor-structure relationship. Disadvantaged students who succeed represent a sociological challenge in the attempt to understand atypical situations and to identify the institutional processes and the structural opportunities that facilitate them, reducing ethnic inequalities in education. This framework is the starting point of the Su.Per. project (Success in educational pathways of students with immigrant background), based on the collection of written autobiographies of 65 imm…

Improving the Effect of Transcranial Alternating Current Stimulation (tACS): A Systematic Review

2021

With the development of electrical stimulation technology, traditional transcranial alternating current stimulation (tACS) technology has been found to have the drawback of not targeting a specific area accurately. Studies have shown that optimizing the number and position of electrodes during electrical stimulation has a very good effect on enhancing brain stimulation accuracy. At present, an increasing number of laboratories have begun to optimize tACS. However, there has been no study summarizing the optimization methods of tACS. Determining whether different optimization methods are effective and the optimization approach could provide information that could guide future tACS research. …

A New Reliable Performance Analysis Template for Quantifying Action Variables in Elite Men’s Wheelchair Basketball

2019

This study aimed to develop a valid and reliable performance analysis template for quantifying team action variables in elite men’s wheelchair basketball. First action variables and operational definitions were identified by the authors and verified by an expert panel of wheelchair basketball coaching staff in order to establish expert validity. A total of 109 action variable were then placed into 17 agreed Categorical Predictor Variable categories. The action variables were then used to develop a computerized performance analysis template for post-event analysis. Each possession (n = 200) from an international men’s wheelchair basketball game was analyzed by the first author on two occasio…
