Skolotāju piesaiste Latvijas vispārizglītojošajās skolās un tās pilnveides iespējas
2019
Skolotāju trūkums Latvijas skolās ir bijis īpaši aktuāls kopš ekonomiskās krīzes 2007-2010.gadā. Krīzes laikā daudzi skolotāji pensijas vecumā izlēma beigt skolotāju karjeru un kopš tā brīža Latvijas skolas ir izjutušas skolotāju trūkumu, it īpaši dabaszinību priekšmetos un angļu valodā. Skolotājiem pārtraucot darbu skolā, viņu vietā nav nācis pietiekami daudz jauno skolotāju. Lai arī Latvijas universitātes izglīto pietiekamu skaitu jauno skolotāju, bieži vien jaunie skolotāji neaiziet strādāt uz skolu un izvēlas citu karjeras attīstību. Kritiski ir tas, ka Latvijas skolu direktoriem nemitīgi aktuāls ir jautājums, kur atrast vajadzīgos skolotājus. Šī maģistra darba mērķis ir teorētiski izpē…
Means of 2D and 3D Shapes and Their Application in Anatomical Atlas Building
2015
This works deals with the concept of mean when applied to 2D or 3D shapes and with its applicability to the construction of digital atlases to be used in digital anatomy. Unlike numerical data, there are several possible definitions of the mean of a shape distribution and procedures for its estimation from a sample of shapes. Most popular definitions are based in the distance function or in the coverage function, each with its strengths and limitations. Closely related to the concept of mean shape is the concept of atlas, here understood as a probability or membership map that tells how likely is that a point belongs to a shape drawn from the shape distribution at hand. We devise a procedur…

An atlas of megadroughts in Europe and in the Mediterranean Basin during the Common Era provides insights into climate variability.
Higgs boson studies at the Tevatron
2013
We combine searches by the CDF and D0 Collaborations for the standard model Higgs boson with mass in the range 90-200 GeV/c2 produced in the gluon-gluon fusion, WH, ZH, tt̄H, and vector boson fusion processes, and decaying in the H→bb̄, H→W+W-, H→ZZ, H→τ+τ-, and H→γγ modes. The data correspond to integrated luminosities of up to 10 fb-1 and were collected at the Fermilab Tevatron in pp̄ collisions at √s=1.96 TeV. The searches are also interpreted in the context of fermiophobic and fourth generation models. We observe a significant excess of events in the mass range between 115 and 140 GeV/c2. The local significance corresponds to 3.0 standard deviations at mH=125 GeV/c2, consistent with the…
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 …

The New European Wind Atlas Model Chain
2020
The New European Wind Atlas (NEWA), the largest European project on wind resource assessment technology, has developed mesoscale-to-microscale wind atlas and site assessment methodologies alongside a validation strategy that leverages data from large field experiments as well as wind resource campaigns from industry through a formal verification and validation process. A probabilistic wind atlas approach, based on a multi-physics ensemble, provides means to quantify the uncertainty associated to the mesoscale configuration. Offline meso-micro coupling has been adopted to provide a modular approach for microscale models of different fidelities to share common mesoscale input data. An opensou…
SINCONAPP: A Computerized learning tool for CBCT normal anatomy and variants of the nose and paranasal sinuses
2014
1. Purpose To supply an useful learning tool aimed to interactively display on mobile devices normal anatomy and variants of the nose and paranasal sinuses as seen on CBCT images. 2. Methods and Materials Images Images of the nose and paranasal sinuses were derived by a study series acquired by a CBCT device. CBCT studies of the paranasal sinuses were acquired in patients referred for nasal obstruction or sinusitis with the following parameters: 90 kVp, 12.5 mA, 20 s rotation time, FOV 13 x 14.5 cm, 0.25 x 0.25 x 0.25 mm voxel size. Software The application has been developed for iOS based mobile devices through the platform XCode provided by Apple®, and it is developed using the Objective-…
Innovations in the Art of Microneurosurgery for Reaching Deep-Seated Cerebral Lesions.
2019
Deep-seated cerebral lesions have fascinated and frustrated countless surgical innovators since the dawn of the microneurosurgical era. To determine the optimal approach, the microneurosurgeon must take into account the characteristics and location of the pathological lesion as well as the operator's range of technical expertise. Increasingly, microneurosurgeons must select between multiple operative corridors that can provide access to the surgical target. Innovative trajectories have emerged for many indications that provide more flexible operative angles and superior exposure but result in longer working distances and more technically demanding maneuvers. In this article, we highlight 4 …
