Semi-automated and interactive segmentation of contrast-enhancing masses on breast DCE-MRI using spatial fuzzy clustering

2022

Abstract Multiparametric Magnetic Resonance Imaging (MRI) is the most sensitive imaging modality for breast cancer detection and is increasingly playing a key role in lesion characterization. In this context, accurate and reliable quantification of the shape and extent of breast cancer is crucial in clinical research environments. Since conventional lesion delineation procedures are still mostly manual, automated segmentation approaches can improve this time-consuming and operator-dependent task by annotating the regions of interest in a reproducible manner. In this work, a semi-automated and interactive approach based on the spatial Fuzzy C-Means (sFCM) algorithm is proposed, used to segme…

Fābri slimība Latvijā: fenotipa - genotipa korelācija

2017

Ievads. Andersona-Fābri slimība ir reta iedzimta lizosomālās uzkrāšanās slimība, ko izraisa mutācijas GLA gēnā un traucēta enzīmā α-galaktozidāzes A darbība. Līdz 2015. gadam Latvijā vēl nebija atklāts neviens pacients ar Fābri slimības diagnozi, bet šobrīd jau ir atrasti vairāk nekā 20 cilvēki ar GLA gēna mutācijām. Darba mērķi. Apkopot un analizēt klīnisko informāciju par Latvijā esošajiem pacientiem ar laboratoriski apstiprinātām mutācijām GLA gēnā, veidot šo datu statistisku pārskatu, kā arī raksturot noteiktu mutāciju radītās Fābri slimības fenotipiskās izpausmes un atrast iespējamas fenotipa-genotipa korelācijas. Darba metodes. Pētījumā iekļautas pilngadīgas personas ar ģenētiski apst…

A Trajectory-Driven 3D Non-Stationary mm-Wave MIMO Channel Model for a Single Moving Point Scatterer

2021

This paper proposes a new non-stationary three-dimensional (3D) channel model for a physical millimeter wave (mm-Wave) multiple-input multiple-output (MIMO) channel. This MIMO channel model is driven by the trajectory of a moving point scatterer, which allows us to investigate the impact of a single moving point scatterer on the propagation characteristics in an indoor environment. Starting from the time-variant (TV) channel transfer function, the temporal behavior of the proposed non-stationary channel model has been analyzed by studying the TV micro-Doppler characteristics and the TV mean Doppler shift. The proposed channel model has been validated by measurements performed in an indoor e…

Implementing a Digital Wellness Application into Use : Challenges and Solutions Among Aged People

2020

The ageing population is a growing priority area for policy makers and healthcare providers worldwide. Life expectancy is improving, but at the same time, insufficient physical activity threatens older age. Thus, an important question arises: how to improve the probability of people living a healthy and active life in older age. One potential solution to support physical activity and healthy aging is digital wellness technologies. However, digital wellness technologies are still typically designed for younger populations, yet a growing need and potential also among aged people is prevalent. Aged people are a user group with distinct needs and challenges. The main purpose of this study was t…

Nepārtraukta glikozes monitorēšana 1. tipa cukura diabēta pacientiem - ietekme uz kopējo metabolo kompensāciju un dzīves kvalitātes novērtējuma param…

2019

1.tipa cukura diabēts ir hroniska autoimūna slimība ar tai pavadošām akūtām un hroniskām diabēta komplikācijām. Straujas glikēmijas svārstības veicina šo komplikāciju attīstību, tāpēc ir nepieciešams izvērtēt glikēmisko variabilitāti diabēta pacientiem. Nepārtrauktās glikozes monitorēšana sniedz iespēju efektīvi izvērtēt glikēmijas izmaiņas ilgākā laika periodā, piefiksējot visas glikozes līmeņa izmaiņas diennaktī, kā arī to saistību ar insulīna injekcijām un fiziskajām aktivitātēm. Pētījuma mērķis bija noskaidrot, cik pareizi un kā pacienti ikdienas dzīvē kontrolē savu cukura līmeni asinīs, kā arī analizēt hipoglikēmiju biežumu un iemeslus un izvērtēt kopējo metabolo kompensāciju. Tika ana…

Parasitismo intestinal en población infantil de los departamentos del Pacífico Nicaragüense

2014

Formando parte de los estudios encaminados al conocimiento del parasitismo intestinal en la población infantil nicaragüense, la presente Tesis Doctoral tiene como objetivo básico abordar el parasitismo intestinal en los diferentes Departamentos que conforman la Región Pacífico, excepción hecha del Departamento de Managua. Para ello se ha estudiado coproparasitológicamente un total de 1881 sujetos (939 niños y 942 niñas), de edades comprendidas entre 0 y 15 años, procedentes de los Departamentos de Chinandega, León, Masaya, Carazo, Granada y Rivas. El espectro enteroparasitario ha quedado conformado por un mínimo de 20 especies (13 de protozoos y 7 especies de helmintos). Desde el punto de v…

Measurement of hard double-parton interactions inW(???) + 2-jet events at $\sqrt{s}\,=7$ TeV with the ATLAS detector

2013

The production of W bosons in association with two jets in proton–proton collisions at a centre-of-mass energy of √s=7 TeV has been analysed for the presence of double-parton interactions using data corresponding to an integrated luminosity of 36 pb[superscript −1], collected with the ATLAS detector at the Large Hadron Collider. The fraction of events arising from double-parton interactions, f[superscript (D) over subscript DP], has been measured through the p[subscript T] balance between the two jets and amounts to f[superscript (D) over subscript DP] = 0.08 ± 0.01 (stat.) ± 0.02 (sys.) for jets with transverse momentum p[subscript T] > 20 GeV and rapidity |y| < 2.8. This corresponds to a …
