The influence of dataset size on the performance of cell outage detection approach in LTE-A networks

2015

The configuration and maintenance of constantly evolving mobile cellular networks are getting more and more complex and hence expensive. Self-Organizing Networks (SON) concept is an umbrella term for the set of automated solutions for network operations proposed by 3rd Generation Partnership Project (3GPP) group. Automated cell outage detection is one of the components of SON functionality. In early studies our research group developed data-driven approach for the detection of malfunctioning cells. In this paper we investigate the performance of the proposed solution as a function of the density of active users and the size of observation interval. The evaluation is conducted in Long Term E…

Indistinguishability of Elementary Systems as a Resource for Quantum Information Processing.

2017

Typical elements of quantum networks are made by identical systems, which are the basic particles constituting a resource for quantum information processing. Whether the indistinguishability due to particle identity is an exploitable quantum resource remains an open issue. Here we study independently prepared identical particles showing that, when they spatially overlap, an operational entanglement exists which can be made manifest by means of separated localized measurements. We prove this entanglement is physical in that it can be directly exploited to activate quantum information protocols, such as teleportation. These results establish that particle indistinguishability is a utilizable …

The role of circulating and exosomal miRNAs as biomarkers of drug-resistant epilepsy

Epilepsy is estimated to affect about 65 million individuals worldwide, with up to 30 percent of drug-resistant patients who do not have remission despite appropriate therapy with antiepileptic drugs (AEDs). Therefore, it is important to distinguish drug-resistant epilepsy early in the course of disease to start a specific therapeutical approach as soon as possible. Recently circulating miRNAs have been proposed as promising biomarkers for different neurodegenerative disorders, including epilepsy. MiRNAs are a class of small non-coding RNA that regulate gene expression at a post-transcriptional level. The regulatory mechanisms controlling translation of mRNA transcripts represents to date a…

Chemical composition of the essential oil of Elaeoselinum asclepium (L.) Bertol subsp. meoides (Desf.) Fiori (Umbelliferae) collected wild in Central…

2020

In the present study, the chemical composition of the essential oils from flowers and leaves of Elaeoselinum asclepium(L.) Bertol subsp. meoides(Desf.) Fiori collected in Central Sicily was evaluated by GC and GC-MS. The main volatile components of the flowers were alpha-phellandrene (42.5%), terpinolene (15.7%), p-cymene (11.6%) and beta-phellandrene (10.2%), whereas the ones of the leaves were p-cymene (44.0%), alpha-pinene (13.2%), alpha-phellandrene (11.0%), beta-phellandrene (10.2%) and beta-pinene (9.2%). Furthermore, the antibacterial and antifungal activities against some microorganisms infesting historical art craft were determined. The essential oil from leaves (EL) showed to be p…

Longitudinal and cross-sectional associations of adherence to 24-hour movement guidelines with cardiometabolic risk

2022

This study aimed to examine 1) adherence to 24-hour movement guidelines over a 2-year follow-up in children aged 6-8 years and 2) association of this adherence with cardiometabolic risk factors. Physical activity and sleep were assessed by a monitor combining heart rate and accelerometry measurements. Screen time was reported by the parents. Body fat percentage, waist circumference, blood glucose, serum insulin, plasma lipids and blood pressure were assessed, and a cardiometabolic risk score was calculated using z-scores. Children were classified as meeting the guidelines if they had on average ≥60min/day of moderate-to-vigorous physical activity during the valid days; ≤120min/day of screen…

QCD NLO with Powheg matching and top threshold matching in WHIZARD

2016

We present the status of the automation of NLO processes within the event generator WHIZARD. The program provides an automated FKS subtraction and phase space integration over the FKS regions, while the (QCD) NLO matrix element is accessed via the Binoth Les Houches Interface from an externally linked one-loop program. Massless and massive test cases and validation are shown for several e+e- processes. Furthermore, we discuss work in progress and future plans. The second part covers the matching of the NRQCD prediction with NLL threshold resummation to the NLO continuum top pair production at lepton colliders. Both the S-wave and P-wave production of the top pair are taken into account in t…

Structural distortions in homoleptic (RE)4A (E = O, S, Se; A = C, Si, Ge, Sn): Implications for the CVD of tin sulfides

2001

The structures of Sn(SBut)4 and Sn(SCy)4 have been determined and adopt S4 and D2 conformations respectively; the anion [(PhS)Sn3]−, as its Ph4P+ salt, has a structure approaching Cs symmetry. In all three compounds, there are large variations in the ∠S–Sn–S within the same molecule, which have been rationalised in terms of the C–S–Sn–S–C conformations. For Sn(SR)4, the ∠S–Sn–S increases as the conformations change from trans, trans to trans, gauche and gauche, gauche, as the number of eclipsed lone pairs decreases and this rationale is shown to be applicable to a variety of A(ER)4 (A = C, Si, Ge, Sn; E = O, S, Se) and related [Mo(SR)4, Ga(SR)4−] systems. AM1 calculations have been used to …

Šizofrēnijas ārstēšanā izmantojamo kompensējamo medikamentu aprite Smiltenes "UNION MED" aptiekā

2015

Šizofrēnija ir viena no smagākajām psihiskajām saslimšanām, kurai nav pilnībā apzināti tās rašanās iemesli. Tā pārsvarā izpaužas ar dažādām halucinācijām, murgu idejām, domāšanu un emociju traucējumiem, kas bieži kombinējas ar autismu, ambivalenci un anhedoniju. Darba mērķis bija noskaidrot šizofrēnijas ārstēšanā izmantojamo kompensējamo medikamentu apriti Smiltenes „UNION MED” aptiekā un izvērtēt šizofrēnijas pacientus pēc vecuma un dzimuma. Iegūtie dati liecina, ka visvairāk izrakstīts ir atipiskais neiroleptiķis kvetiapīns – 2960 tabletes. Pētījuma laikā tika apkalpoti 45 klienti, no kuriem 24 bija vīrieši. Visvairāk ar šizofrēniju slimo vecuma grupā no 40 līdz 50 gadiem. Biežāk sastopam…

Measurement of the top quark charge in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

2013

A measurement of the top quark electric charge is carried out in the ATLAS experiment at the Large Hadron Collider using 2.05 fb[superscript −1] of data at a centre-of-mass energy of 7 TeV. In units of the elementary electric charge, the top quark charge is determined to be 0.64 ± 0.02 (stat.) ± 0.08 (syst.) from the charges of the top quark decay products in single lepton t[¯ over t] candidate events. This excludes models that propose a heavy quark of electric charge −4/3, instead of the Standard Model top quark, with a significance of more than 8σ.
