Recent Submissions
-
(Institute of Electrical and Electronics Engineers (IEEE), 2019)In this paper, we focus on the coexistence between a MIMO radar and cellular base stations. We study the interfering channel estimation, where the radar is operated in the “search and track” mode, and the BS receives the ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2019)The fifth-generation (5G) air interface, namely, dynamic multiple access (MA) based on multiuser superposition transmission (MUST) and orthogonal MA (OMA), may require a complicated scheduling and heavy signaling overhead. ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2018)In this paper, we consider multiple-input single-output multi-eavesdropper cognitive radio networks (MISOME-CRNs), where a secondary user (SU) aims to transmit confidential information to a legitimate SU receiver in the ...
-
(MIT Press, 2014)Verbs and nouns are fundamental units of language, but their neural instantiation remains poorly understood. Neuro- psychological research has shown that nouns and verbs can be damaged independently of each other, and ...
-
(Springer, 2020)Aims: Endurance athletes develop cardiac remodeling to cope with increased cardiac output during exercise. This remodeling is both anatomical and functional and shows large interindividual variability. In this study, we ...
-
(Springer, 2015)This study explores the interaction between deceptive language and second language processing. One hundred participants were asked to produce veridical and false statements in either their first or second language. Pupil ...
-
(SIAM (Society for Industrial and Applied Mathematics), 2020)A cut ε-sparsifier of a weighted graph G is a re-weighted subgraph of G of (quasi)linear size that preserves the size of all cuts up to a multiplicative factor of ε. Since their intro- duction by Bencz´ur and Karger ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2019)In this paper, we focus on one of the key technologies for the fifth-generation wireless communication networks, massive multiple-input-multiple-output (mMIMO), by investigating two of its most relevant architectures: ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2018)The purpose of this article is to bestow the reader with a timely study of UAV cellular communications, bridging the gap between the 3GPP standardization status quo and the more forward-looking research. Special emphasis ...
-
(SAGE Publications, 2014)It is well known that multilingual speakers’ nonnative productions are accented. Do these deviations from monolingual productions simply reflect the mislearning of nonnative sound categories, or can difficulties in processing ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2019)What will it take for drones—and the whole associated ecosystem—to take off? Arguably, infallible command and control (C&C) channels for safe and autonomous flying, and high-throughput links for multi-purpose live video ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2018)Nowadays, the demand for wireless mobile services is copious, and will continue increasing in the near future. Mobile cellular operators are therefore looking at the unlicensed spectrum as an economical supplement to ...
-
(Emerald, 2019)Purpose - The combination of the latest advancements in Information and Communication Technolo- gies (ICT) with the latest developments in AutoID technologies, especially Radio Frequency Identification (RFID), brings the ...
-
(John Benjamins Publishing, 2018)The present study investigated language inhibition and cross-language interference as two possible mechanisms of bilingual language control (BLC) that can be affected by Huntington’s disease (HD), a neurodegenerative disease ...
-
(Wiley, 2018)Acquiring and speaking a second language increases demand on the processes of language control for bilingual as compared to monolingual speakers. Language control for bilingual speakers involves the ability to keep the two ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2020)We present a color matching method that, given two different views of the same scene taken by two cameras with unknown settings and unknown internal parameter values, and encoded with unknown non-linear curves, is able to ...
-
(Frontiers, 2020)The emergence and development of cognitive strategies for the transition from exploratory actions towards intentional problem-solving in children is a key question for the understanding of the development of human cognition. ...
-
(Karger (S. Karger AG), 2020)In fetal cardiology, imaging (especially echocardiography) has demonstrated to help in the diagnosis and monitoring of fetuses with a compromised cardiovascular system potentially associated with several fetal conditions. ...
-
(Wiley, 2017)We study the news reading behavior of several hundred thousand users on 65 highly visited news sites. We focus on a specific phenomenon: users reading several articles related to a particular news development, which we ...
-
(American Institute of Physics (AIP), 2020)We numerically study a network of two identical populations of identical real-valued quadratic maps. Upon variation of the coupling strengths within and across populations, the network exhibits a rich variety of ...
