Search for scalar leptoquarks in pp collisions at $\sqrt{s}$=13 TeV with the ATLAS experiment
2016
An inclusive search for a new-physics signature of lepton-jet resonances has been performed by the ATLAS experiment. Scalar leptoquarks, pair-produced in pp collisions at s √s = 13 TeV at the large hadron collider, have been considered. An integrated luminosity of 3.2 fb-1, corresponding to the full 2015 dataset was used. First (second) generation leptoquarks were sought in events with two electrons (muons) and two or more jets. The observed event yield in each channel is consistent with Standard Model background expectations. The observed (expected) lower limits on the leptoquark mass at 95% confidence level are 1100 and 1050 GeV (1160 and 1040 GeV) for first and second generation leptoqua…
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…
Underground investigation of extensive air showers spectra at high energy range of cosmic rays and other research in the Pyhäsalmi mine
2020
Abstract High energy particles reaching the Earth’s atmosphere are known as cosmic rays. As a result of interactions with nuclei of air molecules, cosmic rays induce showers of secondary particles, which can be divided into 3 components: electromagnetic, hadronic and muonic components. The Experiment with Multi Muon Array (EMMA), located at the depth of 75 m in the Pyhäsalmi mine in Finland, investigates the muonic component of the Extensive Air Showers (EAS) to deduce the direction, energy, and the mass of the primary cosmic ray particles. In this paper we give a concise description and methodology used by EMMA followed by a brief review of the C14 experiment. Finally, we review the feasib…
Festivāla “Adwards” (2017–2021) televīzijas reklāmu retoriskā un auditorijas uztveres un reakciju analīze
2022
Bakalaura darbs “Festivāla “Adwards” (2017–2021) televīzijas reklāmu retoriskā un auditorijas uztveres un reakciju analīze” izstrādāts, lai konstatētu kā retorika tiek izmantota, šajā gadījumā godalgotās, reklāmās un kādas ir reklāmu uztvērēju reakcijas, attieksmes, viedokļi, uzskati par izmantotajiem retoriskajiem elementiem. Darba teorētisko pamatu veido trīs nodaļas. Pirmā nodaļa ir teorētisks apraksts par to kas ir retorika, kurā tiek apskatīta retorikas definīcija, retoriskā trijstūra princips, tā izpausmes reklāmā, kā arī vizuālā un verbālā retorika. Nākošajā nodaļā tiek apskatīta reklāma un audiovizuālā reklāma, ietverot aprakstus par reklāmas definīciju un mērķiem, kā arī apskatus p…
教員 21 世紀型スキルに資するグローバル教員研修に関する実践的研究 ― Edu21st 尺度による自己効力感の変容に着目してー [Teachers’ self-efficacy on 21st century skills : A case study of an in-service teac…
2022
本研究の目的は，大学教員養成におけるグローバル教員研修が，大学院生（現 職教員・大学生）の「教員 21 世紀型スキル」に関する自己効力感にどのような変容を もたらすかを明らかにすることである。研修は，１ . 対話型ボトムアップ研修，２ ．フィン ランドの教育改革研修，及び，３ ．教科連携の CLIL・STEAM に拠る授業訪問を特徴 とする。次世代の児童・生徒が，学びを実社会へ転移するような教育を実現する教員の 21 世紀型スキルとは何か，国際間比較をとおした俯瞰的な研修を目指す。研究方法は， 『Edu 21st：教員 21 世紀型スキルの自己効力感尺度』の 47 質問項目をもちいた事前 と事後の変容，およびポートフォリオ記述分析である。その結果，Edu21st（３ 因子構 造）で差が認められ，「分析的デザイン思考能力」で最も変化が大きいことが明らかにな り，異分野連携の協働中に起こる異質な考えに対する葛藤への価値付けが見られた。 peerReviewed
