Search for the Decay of the Higgs Boson to Charm Quarks with the ATLAS Experiment
2018
A direct search for the standard model Higgs boson decaying to a pair of charm quarks is presented. Associated production of the Higgs and Z bosons, in the decay mode ZH→ℓ+ℓ−c¯c is studied. A data set with an integrated luminosity of 36.1 fb−1 of pp collisions at √s=13TeV recorded by the ATLAS experiment at the LHC is used. The H→c¯c signature is identified using charm-tagging algorithms. The observed (expected) upper limit on σ(pp→ZH)×B(H→c¯c) is 2.7 (3.9+2.1−1.1) pb at the 95% confidence level for a Higgs boson mass of 125 GeV, while the standard model value is 26 fb.
Dynamics of a harmonic oscillator coupled with a Glauber amplifier
2020
A system of a quantum harmonic oscillator bi-linearly coupled with a Glauber amplifier is analysed considering a time-dependent Hamiltonian model. The Hilbert space of this system may be exactly subdivided into invariant finite dimensional subspaces. Resorting to the Jordan-Schwinger map, the dynamical problem within each invariant subspace may be traced back to an effective SU(2) Hamiltonian model expressed in terms of spin variables only. This circumstance allows to analytically solve the dynamical problem and thus to study the exact dynamics of the oscillator-amplifier system under specific time-dependent scenarios. Peculiar physical effects are brought to light by comparing the dynamics…
Інбаунд маркетинг: прикладні аспекти просування товарів і послуг в e-commerce
2019
This paper summarizes the features of the functioning of e-commerce in Ukraine. It has been proven that the activity of e-shops as important subjects of the e-commerce market is underregulated. This leads to consumer dissatisfaction with service quality in the online environment. The necessity of criteria creation was shown, which give them opportunities to e-shops management improve their service and enhance the level of satisfaction of target consumers, primarily based on the effective use of the newest method of promoting goods and services in e-commerce - inbound marketing on the example of infant nutrition. Rating evaluation of functional characteristics of infant nutrition e-shops was…
The “Diabetes Comorbidome”: A Different Way for Health Professionals to Approach the Comorbidity Burden of Diabetes
2022
(1) Background: The disease burden related to diabetes is increasing greatly, particularly in older subjects. A more comprehensive approach towards the assessment and management of diabetes’ comorbidities is necessary. The aim of this study was to implement our previous data identifying and representing the prevalence of the comorbidities, their association with mortality, and the strength of their relationship in hospitalized elderly patients with diabetes, developing, at the same time, a new graphic representation model of the comorbidome called “Diabetes Comorbidome”. (2) Methods: Data were collected from the RePoSi register. Comorbidities, socio-demographic data, severity and comorbidit…
Variabilitat en la realització del contrast en les sibilants sordes del català i del romanés
2021
El romanés i el valencià presenten un contrast similar entre la sibilant no palatal /s/ i la sibilant palatal /?/, però l’articulació de les dues consonants presenta diferències entre les dues llengües. D’una banda, en romanés /s/ es realitza com a dental, més avançada que en valencià; de l’altra, /?/ presenta en romanés un grau de palatalitat major, amb més endarreriment articulatori que en valencià. El primer objectiu és descriure les característiques acústiques d’aquestes consonants a partir del centre de gravetat i comprovar si aquest moment espectral és un bon indicador per a caracteritzar /s/ i /?/ en les llengües estudiades. El segon objectiu és determinar si existeixen diferències e…
