Abstract We extend the classical Carathéodory extension theorem to quasiconformal Jordan domains (Y, dY ). We say that a metric space (Y, dY ) is a quasiconformal Jordan domain if the completion ̄Y of (Y, dY ) has finite Hausdorff 2-measure, the boundary ∂Y = ̄Y \ Y is homeomorphic to 𝕊1, and there exists a homeomorphism ϕ: 𝔻 →(Y, dY ) that is quasiconformal in the geometric sense. We show that ϕ has a continuous, monotone, and surjective extension Φ: 𝔻 ̄ → Y ̄. This result is best possible in this generality. In addition, we find a necessary and sufficient condition for Φ to be a quasiconformal homeomorphism. We provide sufficient conditions for the restriction of Φ to 𝕊1 being a quasi…
PELIGROSIDAD A LOS MOVIMIENTOS DE LADERA EN LA VERTIENTE MERIDIONAL DE SIERRA NEVADA (GRANADA) A PARTIR DE LA ESTIMACIÓN MULTI-TÉCNICA DE LA ACTIVIDAD
2012
El presente trabajo aborda la cartografía de la susceptibilidad y la peligrosidad a los movimientos de ladera, en un ambiente montañoso, con información limitada sobre su actividad. El análisis y validación de la susceptibilidad se realizada mediante un modelo elaborado a partir del ModelBuilder™ de ArcGIS basado en el Método de la Matriz en un SIG. Dicho modelo necesita una cartografía previa de los movimientos, un MDE y un análisis discriminante de los factores determinantes de la estabilidad. Los datos del análisis reflejan que el 15% de la zona estudiada muestra una susceptibilidad a los movimientos de moderada a muy alta que, a su vez, coincide con lugares donde se encuentran la mayorí…
On a Continuous Sárközy-Type Problem
2022
Abstract We prove that there exists a constant $\epsilon> 0$ with the following property: if $K \subset {\mathbb {R}}^2$ is a compact set that contains no pair of the form $\{x, x + (z, z^{2})\}$ for $z \neq 0$, then $\dim _{\textrm {H}} K \leq 2 - \epsilon $.
Uz pierādījumiem balstīts opioīdu pielietojums paliatīvajā aprūpē
2018
Paliatīvā aprūpe ir pacientu aprūpe, kuru radikāla izārstēšana nav iespējama. Latvijā paliatīvās aprūpes pakalpojumus stacionārā 2016. gadā izmantoja 3554 pacienti. Latvijas Onkoloģijas centra Paliatīvās aprūpes nodāļā 99% pacienti ir ar onkoloģisku saslimšanu. Biežākais simptoms šiem pacientiem ir sāpes. Pētījuma mērķis ir noskaidrot pacientu zināšanas par opioīdu pielietojumu paliatīvā aprūpē, kā arī par paliatīvo aprūpi. Pētījums balstīts uz Latvijas Onkoloģijas centra Paliatīvās aprūpes nodaļas pacientu anketēšanu un iegūto rezultātu analīzi. Respondentu anketēšanu veica šī darba autors. Pētījumā piedalījās 50 respondenti: 31 sieviete; 19 vīrieši, kuru vidējais vecums ir 68 gadi. Respon…
Fast simulation of muons produced at the SHiP experiment using Generative Adversarial Networks
2019
This paper presents a fast approach to simulating muons produced in interactions of the SPS proton beams with the target of the SHiP experiment. The SHiP experiment will be able to search for new long-lived particles produced in a 400~GeV$/c$ SPS proton beam dump and which travel distances between fifty metres and tens of kilometers. The SHiP detector needs to operate under ultra-low background conditions and requires large simulated samples of muon induced background processes. Through the use of Generative Adversarial Networks it is possible to emulate the simulation of the interaction of 400~GeV$/c$ proton beams with the SHiP target, an otherwise computationally intensive process. For th…
The experimental facility for the Search for Hidden Particles at the CERN SPS
2019
The Search for Hidden Particles (SHiP) Collaboration has shown that the CERN SPS accelerator with its 400 $\mathrm{\small GeV/c}$ proton beam offers a unique opportunity to explore the Hidden Sector. The proposed experiment is an intensity frontier experiment which is capable of searching for hidden particles through both visible decays and through scattering signatures from recoil of electrons or nuclei. The high-intensity experimental facility developed by the SHiP collaboration is based on a number of key features and developments which provide the possibility of probing a large part of the parameter space for a wide range of models with light long-lived superweakly interacting particles…
The magnet of the scattering and neutrino detector for the SHiP experiment at CERN
2019
The Search for Hidden Particles (SHiP) experiment proposal at CERN demands a dedicated dipole magnet for its scattering and neutrino detector. This requires a very large volume to be uniformly magnetized at B > 1.2 T, with constraints regarding the inner instrumented volume as well as the external region, where no massive structures are allowed and only an extremely low stray field is admitted. In this paper we report the main technical challenges and the relevant design options providing a comprehensive design for the magnet of the SHiP Scattering and Neutrino Detector.

Rekurento neironu tīklu novērtēšanas sistēma
2021
Darba “Rekurento neironu tīklu novērtēšanas sistēma” ietvaros tika izstrādāta sistēma, kurā var uztrenēt rekurento neironu tīklu arhitektūras uz dažādiem uzdevumiem, tām automātiski piemeklējot optimālos tīkla parametrus, un pārbaudīt uz tiem sasniegtos rezultātus, ar mērķi objektīvi novērtēt konkrēta rekurentā neironu tīkla efektivitāti. Sistēmu ir paredzēts lietot dziļās mašīnmācīšanās pētniecībā, jaunu rekurento neironu tīklu izstrādē un testēšanā, lai noteiktu vai jaunizveidotie neironu tīkli ir labāki par jau eksistējošajiem uz konkrētiem uzdevumiem.
