A set of N-heteroquinones, deriving from oligoacenes, have been recently proposed as n-type organic semiconductors with high electron mobilities in thin-film transistors. Generally speaking, this class of compounds self-assembles in neighboring π-stacks linked by weak hydrogen bonds. We aim at theoretically characterizing here the sequential charge transport (hopping) process expected to take p...

To explore the viability of a revised and more differentiated scoring system for use with the Gerontological Apperception Test (GAT; Wolk & Wolk, 1971), 102 older adults (mean age = 68.3 years) were administered the GAT. Scoring criteria were developed to reflect a variety of constructs speaking to the interpersonal, health-related, and intrapsychic dimensions of the experience of later life. F...

The article is devoted to the issue of training primary school teachers use Google services in teaching English pupils. organizational and pedagogical conditions for this process are considered. In it focused on a need create holistic system knowledge, skills abilities by future junior It determined that purpose formation foreign language communicative competence, provided language, speech soci...

John Dilworth How can it be true that one sees a lake when looking at a picture of a lake, since one's gaze is directed upon a flat dry surface covered in paint? An adequate contemporary explanation cannot avoid taking a theoretical stand on some fundamental cognitive science issues concerning the nature of perception, of pictorial content, and of perceptual reference to items that, strictly sp...

The problem of safe locomotion of legged and wheeled robots, when trying to avoid falling, tipping over or hitting obstacles, appears to be a problem of viability and not of Lyapunov stability. Theoretically speaking, viability and Model Predictive Control are unquestionably related, but both can quickly lead to untractable numerical problems. We present here a promising approach for the proble...

The loss in performance caused by mismatch between train and test material suggests a need for task specific acoustic models, especially for highly demanding tasks. However, since the training of these models is extremely expensive, general pur­ pose models are more attractive. In this paper we address the impact of mismatch in speaking style and task. We trained three sets of acoustic models o...

In this paper, we investigate Residue Number System (RNS) to decimal conversion which is an important issue concerning the utilization of RNS numbers in Digital Signal Processing (DSP) applications. We propose a reverse converter using the moduli set {2n+1, 2n, 2n−1}. First, we show that this converter does not require the computation of multiplicative inverses. Next, we simplify the Chinese Re...

acoustic analysis of speech is a powerful, noninvasive, and cost effective tool to study different aspects of motor speech disorders such as the dysarthria associated with pd. in this presentation we will discuss the rationale for using acoustic analysis, its advantages and disadvantages, and methods to overcome these disadvantages. as an example, we will address the use of vowel space area (vs...

In this paper, we propose a novel reverse converter for the moduli set {2n + 1, 2n, 2n − 1}. First, we simplify the Chinese Remainder Theorem in order to obtain a reverse converter that uses mod(2n−1) operations. Next, we present a low complexity implementation that does not require the explicit use of modulo operation in the conversion process and we prove that theoretically speaking it outper...

This paper addresses the significance of rare patterns in linguistic typology. In the Georgian nominal system, vowel deletion in the context of hiatus targets low vowels regardless of position. This pattern is extremely unusual (possibly unique) both in that it targets low vowels (Gouskova 2003) and in that the position of the vowel does not play a role in determining which vowel is deleted (Ca...
