Base station cooperation in MIMO-aided multi-user multi-cell systems employing distributed probabilistic data association based soft reception [PDF]

open access: yes, 2011
Inter-cell co-channel interference (CCI) mitigation is investigated in the context of cellular systems relying on dense frequency reuse. A distributed Base Station (BS) cooperation aided soft reception scheme using the Probabilistic Data Association (PDA)

Ressourcen für den Personal Digital Assistant (PDA) an Bibliotheken / Resources for the Personal Digital Assistant (PDA) at libraries [PDF]

open access: yes, 2008
Support of PDAs is a matter of course for medical libraries in USA. European medical libraries show interest in this mobile technology but lack knowledge about ways and means to advocate PDA usage.

Comparison of Intravenous Paracetamol versus Intravenous Ibuprofen in the Closure of Patent Ductus Arteriosus (PDA) in Preterm Infants

open access: yesپژوهان, 2020
Background and Objective: The Patent Ductus Arteriosus (PDA) occurs in 50% of infants under 1000 g and 30% of infants less than 1500 g. Treatment failure can exacerbate respiratory distress and its complications.

PDA-TOLERATE Trial: An Exploratory Randomized Controlled Trial of Treatment of Moderate-to-Large Patent Ductus Arteriosus at 1 Week of Age

open access: yesJornal de Pediatria, 2018
Objective To compare early routine pharmacologic treatment of moderate‐to‐large patent ductus arteriosus (PDA) at the end of week 1 with a conservative approach that requires prespecified respiratory and hemodynamic criteria before treatment can be given.

On the sizes of DPDAs, PDAs, LBAs

open access: yesTheoretical Computer Science, 2016
There are languages A such that there is a Pushdown Automata (PDA) that recognizes A which is much smaller than any Deterministic Pushdown Automata (DPDA) that recognizes A. There are languages A such that there is a Linear Bounded Automata (Linear Space Turing Machine, henceforth LBA) that recognizes A which is much smaller than ny PDA that recognizes

The Use of Popular Fiction to Present a Professional Scientific Career to High School Students

open access: yesJournal of Microbiology & Biology Education, 2010
In a previous Tips & Tools article, Patricia J. Baynham advocated for the introduction of science to students by hosting scientists in classrooms. We approached the issue from a different perspective.

Relation between the nature of the surface facets and the reactivity of Cu2O nanostructures anchored on TiO2NT@PDA electrodes in the photoelectrocatalytic conversion of CO2 to methanol

open access: yes, 2020
This paper investigates the influence of morphology of Cu2O nanoparticles (cubes, NcCu2O; spheres, NsCu2O; octahedrons, NoCu2O), deposited on TiO2 nanotubes (TiO2NT) coated with PDA, in the photoelectrocatalytic conversion of CO2 to methanol. At low bias

PDA with Independent Counters

open access: yesМоделирование и анализ информационных систем, 2015
Push-down automata with independent counters (PDACs) combine the power of PDAs and Petri Nets. They were developed in [21, 15], as a tool of recognition of languages generated by Categorial Dependency Grammars (CDGs).
