Teorie della coercizione, antipaternalismo e autonomia contrattuale
2013
In this article, I will examine the relations between antipaternalism and coercion theories. According to antipaternalism over himself, over his body and mind, the individual is sovereign, but if his actions are rational and free of coercion. Secondly, I will clarify if the so called unconscionability doctrine about contract law is antipaternalistic or not.
Kuņģa vēža un pirmsvēža stāvokļu saistība ar autoimūnu gastrītu
2016
Ievads. Kuņģa atrofija un H.pylori infekcija ir labi zināmi kuņģa vēža riska faktori, bet autoimūna gastrīta nozīme kuņģa vēža attīstībā nav pilnīgi skaidra. Darba mērķis. Izpētīt antiparietālo šūnu antivielu (APCA) un antivielu pret iekšējo faktoru (IFA) izplatības un vērtību atšķirības pacientiem ar kuņģa vēzi un pirmsvēža stāvokļiem, un saistību ar H.pylori infekciju. Materiāli un metodes. Tika izmeklētas APCA un IFA vērtības un to saistība ar H.pylori IgG vērtībām pacientiem ar morfoloģiski apstiprinātu kuņģa vēzi un pirmsvēža stāvokļiem. Par pozitīvām APCA un IFA vērtībām tika uzskatītas vērtības ≥25 vienībām. Par pozitīvu H.pylori infekciju tika spriests, vadoties pēc IgG rezultātiem …

Modelling and Analysis of Nonstationary Vehicle-to-Infrastructure Channels with Time-Variant Angles of Arrival
2018
In mobile radio channel modelling, it is generally assumed that the angles of arrival (AOAs) are independent of time. This assumption does not in general agree with real-world channels in which the AOAs vary with the position of a moving receiver. In this paper, we first present a mathematical model for the time-variant AOAs. This model serves as the basis for the development of two nonstationary multipath fading channels models for vehicle-to-infrastructure communications. The statistical properties of both channel models are analysed with emphasis on the time-dependent autocorrelation function (ACF), time-dependent mean Doppler shift, time-dependent Doppler spread, and the Wigner-Ville sp…
Slope units-based flow susceptibility model: using validation tests to select controlling factors
2011
A susceptibility map for an area, which is representative in terms of both geologic setting and slope instability phenomena of large sectors of the Sicilian Apennines, was produced using slope units and a multiparametric univariate model. The study area, extending for approximately 90 km2, was partitioned into 774 slope units, whose expected landslide occurrence was estimated by averaging seven susceptibility values, determined for the selected controlling factors: lithology, mean slope gradient, stream power index at the foot, mean topographic wetness index and profile curvature, slope unit length, and altitude range. Each of the recognized 490 landslides was represented by its centroid po…
Impaired circadian heart rate variability in Parkinson’s disease: a time-domain analysis in ambulatory setting
2020
Abstract Background Heart rate variability (HRV) decreases in Parkinson’s disease (PD) and it can be considered a marker for cardiovascular dysautonomia. The purpose of this pilot study is to evaluate long-term time-domain analysis of HRV of PD patients and compare the results with those of matched healthy individuals. Methods Idiopathic PD patients without comorbidity impairing HRV, and age-matched healthy individuals were recruited in a pilot study. A long-term time domain analysis of HRV using 24-h ambulatory ECG was performed. Results Overall, 18 PD patients fulfilling inclusion criteria completed the evaluation (mean age was 55.6 ± 8.8, disease duration: 5.0 ± 4.7). Mean SCOPA-AUT scor…
Level-crossing rate and average duration of fades of non-stationary multipath fading channels
2017
The level-crossing rate (LCR) and average duration of fades (ADF) are important statistical quantities describing the fading behaviour of mobile radio channels. To date, these quantities have only been analysed under the assumption that the mobile radio channel is wide-sense stationary, which is generally not the case in practice. In this paper, we propose a concept for the analysis of the LCR and ADF of non-stationary channels. Rice's standard formula for the derivation of the LCR of wide-sense stationary processes is extended to a more general formula enabling the computation of the instantaneous LCR of non-stationary processes. The application of the new concept results in closed-form ex…
The use of imidazolium group-containing Bronsted acids for masspectrometric determination of biogenic amines in alcoholic beverages
2017
Darbā ir izstrādāta metode sešu biogēno amīnu masspektrometriskai noteikšanai alkoholiskos dzērienos. Metodes pamatā ir kompleksu veidošanās starp biogēniem amīniem un imidazolija grupu saturošu Brensteda skābi, kas nodrošina ātru un selektīvu analīzi bez parauga sagatavošanas. Darba gaitā ir izpētīta vairāku masspektrometra parametru ietekme uz biogēno amīnu kompleksu rašanos, un izvēlētas specifiskās MRM pārejas. Metodes aprobācijai izvēlēti un analizēti astoņi alkoholiskie dzērieni.
Radiomics and Prostate MRI: Current Role and Future Applications
2021
Multiparametric prostate magnetic resonance imaging (mpMRI) is widely used as a triage test for men at a risk of prostate cancer. However, the traditional role of mpMRI was confined to prostate cancer staging. Radiomics is the quantitative extraction and analysis of minable data from medical images; it is emerging as a promising tool to detect and categorize prostate lesions. In this paper we review the role of radiomics applied to prostate mpMRI in detection and localization of prostate cancer, prediction of Gleason score and PI-RADS classification, prediction of extracapsular extension and of biochemical recurrence. We also provide a future perspective of artificial intelligence (machine …
