The implementation of OFDM transmitters typically consists of a discrete DFT matrix and a digital-to-analog (DAC) converter. Many existing results on the analysis of OFDM systems, e.g., spectral roll-off, are based on a convenient analog representation. In this paper, we show that the analog representation and the DFT-based OFDM transmitters are equivalent only in special cases. Using the analo...

Interpolated multiple zeta values introduced by S. Yamamoto are generalized to two kinds of $L$-values. Their double shuffle structure is established algebraically. Then we give the extended relation, Hoffman’s and Kawash

Abstract We develop an open-source python workflow package, py GWBSE to perform automated first-principles calculations within the GW-BSE (Bethe-Salpeter) framework. is a many body perturbation theory based approach explore quasiparticle (QP) and excitonic properties of materials. GW approximation accurately predicts bandgaps materials by overcoming bandgap underestimation issue more widely use...

An electrical stimulus delivered to a muscle nerve during a maximal voluntary contraction usually produces a twitchlike increment in force. The amplitude of this "interpolated twitch" is widely used to measure voluntary "activation" of muscles. In the present study, a computer model of the human adductor pollicis motoneuron pool was used to investigate factors that affect the interpolated twitc...

This paper addresses fundamental issues related to the modeling of geometric data embedded in high-dimensional spaces. This covers several application fields, including moving objects where trajectories are described in a threeor four-dimensional space, and digital elevation models (DEMs). We show that moving objects and DEMs are specific instances of a broader class of complex spatial data tha...

This paper presents a novel method for radio map construction that simultaneously interpolates the received signal power values over space and frequency domains. Radio maps can be used to improve spectrum management localization systems, which are related wireless systems in general such as cellular Internet of Things (IoT) networks, vehicular communications. Researchers have shown crowdsourcin...

Experiments examining the issue of decay in short-term memory have assumed a single undifferentiated source of processing capacity which cannot be devoted to rehearsal when consumed in the processing of a nonverbal interpolated task. Three experiments reported here call this logic into question, since variations in difficulty in the nonverbal interpolated task failed to affect recall. Slight fo...
