(Elsevier BV, 2022-06)In the authors' previous analysis of the calling paradigms call-by-name and call-by-value through Girard's and Gödel's embeddings into the S4 modal logic, an asymmetry remains: the two paradigms are unified by the call-by-box paradigm of the modal ... -
(Institute of Electrical and Electronics Engineers (IEEE), 2024)Molecular dynamics simulations, with full Coulomb interaction, are used to model short-pulse photoemission from a finite area in a microdiode. We demonstrate three emission regimes, source-limited emission, space-charge-limited emission for short pulses, ...

Piezoresistance characterization of silicon nanowires in uniaxial and isostatic pressure variation (MDPI AG, 2022-08-23)Silicon nanowires (SiNWs) are known to exhibit a large piezoresistance (PZR) effect, making them suitable for various sensing applications. Here, we report the results of a PZR investigation on randomly distributed and interconnected vertical silicon ...

(Frontiers Media SA, 2021-03-19)Background: Despite evidence-based national guidelines for ADHD in the United Kingdom (UK), ADHD is under-identified, under-diagnosed, and under-treated. Many seeking help for ADHD face prejudice, long waiting lists, and patchy or unavailable services, ...
-
(AIP Publishing, 2021-03-14)This Perspective reviews the fundamental physics of space–charge interactions that are important in various media: vacuum gap, air gap, liquids, and solids including quantum materials. It outlines the critical and recent developments since a previous ...

(Frontiers Media SA, 2021-01-28)Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that is associated with risk-taking behaviors, poor self-control, and interpersonal difficulties. Affected individuals have an increased probability of involvement with ...
-
(MDPI AG, 2021-04-27)Antenna structures for modern applications are characterized by complex and unintuitive topologies that are difficult to develop when conventional, experience-driven techniques are of use.In this work, a method for the automatic generation of antenna ...
-
(Institution of Engineering and Technology (IET), 2021-05)Butler matrices represent a popular class of feeding networks for antenna arrays. Large dimensions and the lack of flexibility in terms of achievable output phase difference make conventional Butler structures of limited use for modern communication ...

Low-Cost Unattended Design of Miniaturized 4 × 4 Butler Matrices with Nonstandard Phase Differences (MDPI AG, 2021-01-27)Design of Butler matrices dedicated to Internet of Things and 5th generation (5G) mobile systems-where small size and high performance are of primary concern-is a challenging task that often exceeds capabilities of conventional techniques. Lack of ...

(DIiscrete Mathematics Theoretical Computer Science, 2021-03)In this paper, we study the staircase encoding of permutations, which maps a permutation to a staircase grid with cellsfilled with permutations. We consider many cases, where restricted to a permutation class, the staircase encoding be-comes a bijection ...

(Institute of Electrical and Electronics Engineers (IEEE), 2021)Multiple-input multiple-output (MIMO) antennas are considered to be the key components of fifth generation (5G) mobile communications. One of the challenges pertinent to the design of highly integrated MIMO structures is to minimize the mutual coupling ...

(Menntavísindastofnun, Menntavísindasvið, Háskóli Íslands, 2019-09-13)Tilgangur rannsóknarinnar var að skoða áhrif þjálfunar á orðaforða barns á þriðja ári, sem seint var til máls. Einn þátttakandi var í rannsókninni. Við upphaf rannsóknarinnar var hann 30 mánaða, notaði rúmlega 160 orð og var ekki farinn að tengja saman ...
