Evaluating the extent of patient-centred care in a selection of ESC guidelines
2019
AIMS: Patient-centred care (PCC) is the cornerstone for healthcare professionals to promote high quality care for patients with cardiovascular conditions. It is defined as 'Providing care that is respectful of, and responsive to, individual patient preferences, needs and values, and ensuring that patient values guide all clinical decisions'. PCC can improve patient outcomes and allow patients and healthcare professionals to manage care collaboratively using best available evidence. However, there is no clear understanding how extensively guidelines incorporate PCC recommendations. The aim of the study was to evaluate the incorporation of PCC into a selection of guidelines published by the E…
Towards Evidence-Based Academic Advising Using Learning Analytics
2018
Academic advising is a process between the advisee, adviser and the academic institution which provides the degree requirements and courses contained in it. Content-wise planning and management of the student’ study path, guidance on studies and academic career support is the main joint activity of advising. The purpose of this article is to propose the use of learning analytics methods, more precisely robust clustering, for creation of groups of actual study profiles of students. This allows academic advisers to provide evidence-based information on the study paths that have actually happened similarly to individual students. Moreover, academic institutions can focus on management and upda…
Kadastrālo vērtību palielinājuma un nekustamo īpašumu nodokļu reformas ietekme uz Latvijas pašvaldībām
2021
Darba “Kadastrālo vērtību palielinājuma un nekustamo īpašumu nodokļu reformas ietekme uz Latvijas pašvaldībām” mērķis ir apskatīt un analizēt informāciju par kadastrālo vērtību un nekustamo īpašumu nodokļu politiku Latvijā, un to ietekmi uz Latvijas pašvaldībām. Darba ietvaros tiks apskatīta informācija par kadastrālo vērtību palielinājuma un nekustamo īpašuma nodokļu reformas administratīvo, sociālo un fiskālo ietekmi. Darba teorētiskajai daļai izmantota politikas teorija. Darba pētījums ir fokusēts uz administratīvās, sociālās, fiskālās un ekonomiskās analīzes ietekmi uz Latvijas pašvaldībām. Pētījuma rezultātā konstatēts, ka plānotā nekustāmā īpašuma reforma ir nepilnīga. Darba pētījuma …
G-Spaces and Kaluza-Klein Theory
1988
G-spaces are present whenever symmetries are relevant in physics. After a short introduction to this subject, spontaneous symmetry breaking in elementary particle physics is considered from this point of view. Kaluza-Klein theory is discussed in a purely geometrical formulation. Some results in connection with the geometrical compactification scheme are presented.
Weakly Supervised Object Detection in Artworks
2018
We propose a method for the weakly supervised detection of objects in paintings. At training time, only image-level annotations are needed. This, combined with the efficiency of our multiple-instance learning method, enables one to learn new classes on-the-fly from globally annotated databases, avoiding the tedious task of manually marking objects. We show on several databases that dropping the instance-level annotations only yields mild performance losses. We also introduce a new database, IconArt, on which we perform detection experiments on classes that could not be learned on photographs, such as Jesus Child or Saint Sebastian. To the best of our knowledge, these are the first experimen…
On prefix normal words and prefix normal forms
2016
A $1$-prefix normal word is a binary word with the property that no factor has more $1$s than the prefix of the same length; a $0$-prefix normal word is defined analogously. These words arise in the context of indexed binary jumbled pattern matching, where the aim is to decide whether a word has a factor with a given number of $1$s and $0$s (a given Parikh vector). Each binary word has an associated set of Parikh vectors of the factors of the word. Using prefix normal words, we provide a characterization of the equivalence class of binary words having the same set of Parikh vectors of their factors. We prove that the language of prefix normal words is not context-free and is strictly contai…

Reversible Photochemical Control of Doping Levels in Supported Graphene
2017
Controlling the type and density of charge carriers in graphene is vital for a wide range of applications of this material in electronics and optoelectronics. To date, chemical doping and electrostatic gating have served as the two most established means to manipulate the carrier density in graphene. Although highly effective, these two approaches require sophisticated graphene growth or complex device fabrication processes to achieve both the desired nature and the doping densities with generally limited dynamic tunability and spatial control. Here, we report a convenient and tunable optical approach to tune the steady-state carrier density and Fermi energy in graphene by photochemically c…
Multilevel pattern generation by GaN laser lithography: an application to beam shaper fabrication
2006
The new GaN lasers represent a unique combination of compactness, reliability, energy efficiency, and short wavelength. With respect to the previous state of the art in direct laser write lithography, based on gas lasers, this is resulting in a breakthrough, and is opening the way to real desktop micropatterning. The field of diffractive optics can immediately benefit by the availability of a new breed of pattern generators, based on such sources, mainly for fast turnaround device development. This paper presents the technical advantages involved in the use of 405 nm GaN lasers for one-step multilevel patterning. Beam modulation, exposure control and overall process strategy are discussed. …
