Latviešu valodas morfosintaktiskais marķētājs
2015
Bakalaura darbā aprakstīta morfoloģiskā marķētāja, kas izmanto vairāku klašu vidējo perceptrona mašīnmācīšanās algoritmu, izstrāde latviešu valodai. Darbā izstrādātajam marķētājam ir augsta precizitāte (95,20% un 94,32% - mērīta uz diviem dažādiem korpusiem), kas atbilst labākajiem rezultātiem pasaulē morfoloģiski sarežģītām valodām. Marķētājs salīdzināts ar diviem marķētājiem latviešu valodai, un tam ir labāka precizitāte nekā marķētājam, kas izmanto maksimālās entropijas modeli (94,83% un 91,51%), un nedaudz labāka precizitāte (93,67% un 93,6%) par marķētāju, kas izmanto nosacījumu Markova modeli.

В коммунистических режимах свободное слово было под запретом. Однако некоторые любящие правду писатели (впрочем, не только они, но и вообще люди интеллигентского круга), не боясь преследований, распространяли свои произведения в самиздате и отправляли их за «железный занавес», где другие такие же свободолюбивые люди печатали их, передавали их содержание по радио. Иногда даже удавалось отправлять несколько напечатанных экземпляров назад на родину автора. Таким образом возникло международное сообщество рыцарей справедливости. Какими плохими дядьками, однако, были эти коммунисты! С такой формулировкой, пусть и наивной по форме, вероятно, мог бы согласится каждый. В этой связи непонятно, для че…

Precision Measurement of the First Ionization Potential of Nobelium
2018
One of the most important atomic properties governing an element's chemical behavior is the energy required to remove its least-bound electron, referred to as the first ionization potential. For the heaviest elements, this fundamental quantity is strongly influenced by relativistic effects which lead to unique chemical properties. Laser spectroscopy on an atom-at-a-time scale was developed and applied to probe the optical spectrum of neutral nobelium near the ionization threshold. The first ionization potential of nobelium is determined here with a very high precision from the convergence of measured Rydberg series to be 6.626 21±0.000 05 eV. This work provides a stringent benchmark for st…
Unveiling the strong interaction among hadrons at the LHC
2020
One of the key challenges for nuclear physics today is to understand from first principles the effective interaction between hadrons with different quark content. First successes have been achieved using techniques that solve the dynamics of quarks and gluons on discrete space-time lattices1,2. Experimentally, the dynamics of the strong interaction have been studied by scattering hadrons off each other. Such scattering experiments are difficult or impossible for unstable hadrons3–6 and so high-quality measurements exist only for hadrons containing up and down quarks7. Here we demonstrate that measuring correlations in the momentum space between hadron pairs8–12 produced in ultrarelativistic…
Illustrating a Family. The Printing Press and Political Issues in the "Ritratti della Prosapia et Heroi Moncadi nella Sicilia"
2021
In an early printed book, the presence of a large iconographic apparatus normally reveals a strong effort both in designing its shape and in the financial coverage needed to make it possible. Such effort can be fully explained by paying attention to the scope and target behind its conception. The two volumes of “Ritratti della Prosapia et heroi Moncadi nella Sicilia”, published in 1657 in Valencia, offer a notable example of the political exposure sought after by a noble family, that of Moncada, through the printing press technique and its power of circulation, combined with the attractiveness of family portraits. In particular, the 1657 book, written by Giovanni Agostino Della Lengueglia, …
La imagen de la Concha de Oro en los impresos de la Edad Moderna
2020
For centuries, an image commonly associated with Santiago de Compostela (the shell) has accompanied the city of Palermo as well. Since the classical tradition and medieval literature, and then during the Renaissance and Baroque age, this symbol has been connected with other urban symbols (the rivers, the eagle and trhe Genius of Palermo), thus contributing to its historical identity, although in a rather idealistic form. Therefore, the expression «Golden Shell» has been used repeatedly in a large number of books printed during the Modern Age, with multiple meanings. The main purpose was to show those attributes linked with the city's landscape (wealth and beauty) within a specific political…
Avisos y relaciones manuscritos y impresos sobre catastrofes naturales y sucesos prodigiosos en Sicilia durante el siglo XVIII
2021
In the eighteenth century there is a large number of stories, both handwritten and in print, that describe extraordinary and unlucky events of different kinds: monstrosities, eclipses, or storms, floods, earthquakes, eruptions, etc. These stories, with respect to Sicily, take the form of occasional printed news, although sometimes they may be included in serials organized by different criteria (topographic/chronological/subject). Surviving documents in archives and libraries offer some opportunities to deepen the study of issues concerning the circulation and dissemination of news about the same event, their credibility, their formal characters and content. Very rare printed ephemera and ha…
Nonlocal properties of dynamical three-body Casimir-Polder forces
2005
We consider the three-body Casimir-Polder interaction between three atoms during their dynamical self-dressing. We show that the time-dependent three-body Casimir-Polder interaction energy displays nonlocal features related to quantum properties of the electromagnetic field and to the nonlocality of spatial field correlations. We discuss the measurability of this intriguing phenomenon and its relation with the usual concept of stationary three-body forces.
