Observation of Photon Polarization in theb→sγTransition
2014
This Letter presents a study of the flavor-changing neutral current radiative $B^{\pm} \to K^{\pm}\pi^{\mp}\pi^{\pm}\gamma$ decays performed using data collected in proton-proton collisions with the LHCb detector at $7$ and $8\,$TeV center-of-mass energies. In this sample, corresponding to an integrated luminosity of $3\,\text{fb}^{-1}$, nearly $14\,000$ signal events are reconstructed and selected, containing all possible intermediate resonances with a $K^{\pm}\pi^{\mp}\pi^{\pm}$ final state in the $[1.1, 1.9]\,$GeV/$c^{2}$ mass range. The distribution of the angle of the photon direction with respect to the plane defined by the final-state hadrons in their rest frame is studied in interva…

2021
Komercbanku finansiālā stāvokļa novērtēšanas tēma ietver sevī milzīgo zinātnisko un praktisko vērtību, kas saistīta ar banku stabilu darbības nodrošināšanu. Katram ir saprotams, ka no bankas izvēles ir atkarīga personāla labklājība un finanšu drošība gan fiziskām personām, gan juridiskām personām. Tādējādi tiek veikta finanšu analīze, lai pilnveidotu bankas darbību. Bakalaura darba mērķis ir, pielietojot finanšu analīzes teorētiskās atziņas, veikt AS ”Swedbank” finansiāla stāvokļa analīzi, un, pamatojoties uz pētījuma rezultātiem, izvirzīt secinājumus un izstrādāt priekšlikumus darbības pilnveidošanai. Bakalaura darba autore, veicot AS “Swedbank” finansiālās situācijas analīzi, secina ka ko…
A/S Swedbank finanšu stāvokļa analīze
2018
Mūsdienu komercbankas sistēma atrodas nepārtrauktā mijiedarbībā ar ārējo vidi, it īpaši ar ekonomikas funkcionēšanu. Līdz ar to informācija par to stabilitāti, ko sniedz finanšu analīze, ir svarīga ne tikai potenciālajiem klientiem un pašām kredītiestādēm, bet arī uzraudzības iestādēm. Problēmu agrā diagnostika un komercbanku sistēmas stabilitātes nostiprināšana ļauj mazināt krīžu iespējamību un to sekas. Bakalaura darba mērķis ir veikt Swedbank finansiālā stāvokļa analīzi, izdarīt secinājumus un sniegt priekšlikumus. Bakalaura darba uzdevumi ir izpētīt bankas finanšu pārskatu analīzes metodes, savākt un apkopot informāciju par bankas vēsturi, izanalizēt bankas lomu Latvijas komercbanku sis…
Komercbankas “Swedbank” darbības finanšu analīze
2016
Mūsdienās komercbankas ir cieši saistītas ar sabiedrības ikdienas dzīvi, bet to darbības finanšu analīze sagādā ārējiem lietotājiem problēmas specializētas literatūras trūkuma dēļ. Tāpēc sabiedrība ne vienmēr spēj precīzi noteikt vai ir vērts sadarboties ar komercbanku. Šī diplomdarba mērķis ir veikt komercbankas „Swedbank” darbības finanšu analīzi, veikt secinājumus un noteikt priekšlikumus darbības uzlabošanai. Mērķa sasniegšanai autore raksturoja un analizēja bankas riskus, aktīvu un pašu kapitāla ienesīgumu, bankas darbības vērtējuma koeficientus. Lai gūtu pilnīgu priekšstatu par komercbankas “Swedbank” finanšu analīzes rezultātiem, iegūti koeficienti tiek salīdzināti ar tādiem pašiem k…
Ultra-High-Performance Liquid Chromatography Coupled with Quadrupole Orbitrap High-Resolution Mass Spectrometry for Multi-Residue Analysis of Mycotox…
2020
Cannabidiol (CBD) food supplements made of Cannabis sativa L. extracts have quickly become popular products due to their health-promoting effects. However, potential contaminants, such as mycotoxins and pesticides, can be coextracted during the manufacturing process and placed into the final product. Accordingly, a novel methodology using ultra-high-performance liquid chromatography coupled with quadrupole Orbitrap high-resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS) was developed to quantify 16 mycotoxins produced by major C. sativa fungi, followed by a post-target screening of 283 pesticides based on a comprehensive spectral library. The validated procedure was applied to ten CBD-bas…
'Not as safe as I believed': Differences in perceived and self-reported cycling behavior between riders and non-riders
2021
Cycling behavior remains a key issue for explaining several traffic causalities occurring every day. However, recent studies have shown how the assessment of the own safety-related behaviors on the road may substantially differ from how third parties assess them. Thus, the aim of this study was to evaluate the differences between cyclists’ self-reported behavior and the proxy-reported behavior that other (non-cyclist) road users perceive from bike riders. For this purpose, this study used data from two samples: (i) 1064 cyclists (M = 32.83 years) answering the Cycling Behavior Questionnaire—CBQ, and (ii) 1070 non-cyclists (M = 30.83 years) answering an adapted version of the CBQ for externa…
A Combined Fuzzy and Probabilistic Data Descriptor for Distributed CBIR
2009
With the wide diffusion of digital image acquisition devices, the cost of managing hundreds of digital images is quickly increasing. Currently, the main way to search digital image libraries is by keywords given by the user. However, users usually add ambiguos keywords for large set of images. A content-based system intended to automatically find a query image, or similar images, within the whole collection is needed. In our work we address the scenario where medical image collections, which nowadays are rapidly expanding in quantity and heterogeneity, are shared in a distributed system to support diagnostic and preventive medicine. Our goal is to produce an efficient content-based descript…
Clustering techniques for personal photo album management
2009
In this work we propose a novel approach for the automatic representation of pictures achieving at more effective organization of personal photo albums. Images are analyzed and described in multiple representation spaces, namely, faces, background and time of capture. Faces are automatically detected, rectified and represented projecting the face itself in a common low-dimensional eigenspace. Backgrounds are represented with low-level visual features based on RGB histogram and Gabor filter bank. Faces, time and background information of each image in the collection is automatically organized using a mean-shift clustering technique. Given the particular domain of personal photo libraries, wh…
Serological identification and expression analysis of gastric cancer-associated genes
2002
Serological identification of tumour antigens by recombinant expression cloning has proved to be an effective strategy for the identification of cancer-associated genes having a relevance to cancer aetiology and progression, and for defining possible targets for immunotherapeutic intervention. In the present study we applied this technique to identify immunogenic proteins for gastric cancer that resulted in isolation of 14 distinct serum-reactive antigens. In order to evaluate their role in tumourigenesis and assess the immunogenicity of the identified antigens, we characterised each cDNA clone by DNA sequence analysis, mRNA tissue distribution, comparison of mRNA levels in cancerous and ad…
First experimental study of photon polarization in radiative B0s decays.
2017
The polarization of photons produced in radiative $B^{0}_{s}$ decays is studied for the first time. The data are recorded by the LHCb experiment in $pp$ collisions corresponding to an integrated luminosity of 3fb$^{-1}$ at center-of-mass energies of $7$ and $8$TeV. A time-dependent analysis of the $B^{0}_{s} \to \phi \gamma$ decay rate is conducted to determine the parameter ${\mathcal{A}}^\Delta$, which is related to the ratio of right- over left-handed photon polarization amplitudes in $b \to s \gamma$ transitions. A value of ${\mathcal{A}}^\Delta=-0.98^{\,+0.46\,+0.23}_{\,-0.52\,-0.20}$ is measured. This result is consistent with the Standard Model prediction within two standard deviatio…
