Framework for complex quantum state generation and coherent control based on on-chip frequency combs
2018
Integrated frequency combs introduce a scalable framework for the generation and manipulation of complex quantum states (including multi-photon and high-dimensional states), using only standard silicon chip and fiber telecommunications components.
Optical quantum information processing and storage
2018
Here we report our recent experimental progresses in optical quantum information processing. In particular, the following topics are included. First, we extend the heralding scheme to multi-mode states and demonstrate heralded creation of qutrit states. Next, we demonstrate storage of single-photon states and synchronized release of them. Then, we demonstrate real-time acquisition of quadrature values of heralded states by making use of an exponentially rising shape of wave-packets. Finally, we demonstrate cluster states in an arbitrarily long chain in the longitudinal direction.
Cognitive dysfunction in patients with relapsing-remitting multiple sclerosis
2006
Cognitive dysfunction is considered one of the clinical markers of multiple sclerosis (MS). However, in the literature there are inconsistent reports on the prevalence of cognitive dysfunction, and separate data for the relapsing-remitting (RR) type of the disease are not always presented. In this study, we submitted 461 RRMS patients to a battery of neuropsychological tests to investigate their impairment in various cognitive domains. As a consequence of the exclusion criteria, the sample is not fully representative of the entire population of RRMS patients. In this selected sample, when only the eight scores of a core battery (Mental Deterioration Battery) were considered (with respectiv…
Semantic distance as a critical factor in icon design for in-car infotainment systems
2017
In-car infotainment systems require icons that enable fluent cognitive information processing and safe interaction while driving. An important issue is how to find an optimised set of icons for different functions in terms of semantic distance. In an optimised icon set, every icon needs to be semantically as close as possible to the function it visually represents and semantically as far as possible from the other functions represented concurrently. In three experiments (N = 21 each), semantic distances of 19 icons to four menu functions were studied with preference rankings, verbal protocols, and the primed product comparisons method. The results show that the primed product comparisons me…
Perceived collective burnout: a multilevel explanation of burnout
2011
Building up on the socially induced model of burnout and the job demands-resources model, we examine how burnout can transfer without direct contagion or close contact among employees. Based on the social information processing approach and the conservation of resources theory, we propose that perceived collective burnout emerges as an organizational-level construct (employees' shared perceptions about how burned out are their colleagues) and that it predicts individual burnout over and above indicators of demands and resources. Data were gathered during the first term and again during the last term of the academic year among 555 teachers from 100 schools. The core dimensions of burnout, ex…

Ewald Hering und die Gegenfarbtheorie
1996
Ewald Hering's color-opponent-theory is still considered one of the foundations of the visual sciences. Prior to Hering, Hermann v. Helmholtz introduced a theory of color appearance, which was based primarily on the physical aspects of the stimulus. In contrast to Helmholtz, Hering's theory strongly emphasized the subject's perception of color. As a consequence, Hering considered Helmholtz' theory inadequate. Contrary to some historical accounts, he did not object to Helmholtz's three-receptor explanation for color-mixture. Instead of Helmholtz' fundamental colors red, green, and blue, Hering suggested that the colors possess opponent character: blue-yellow; red-green; and, black-white. Hel…
Physical activity, aerobic fitness, and brain white matter : Their role for executive functions in adolescence
2020
Highlights • Aerobic fitness level, but not physical activity, is related to white matter properties in the brain. • The relation between physical activity and working memory is moderated by fractional anisotropy (FA) of the corpus callosum. • The FA of the corpus callosum and superior corona radiata moderates the relation between aerobic fitness and working memory.
IDENTIFICATION OF CAREER MANAGEMENT SKILLS RELATED PROBLEMS IN THE STUDY PROCESS OF PODOLOGISTS
2016
<p>Despite the competencies acquired in study process, results of learning, diploma and provided guidance measures podologs as same as other young specialists often lack skills to create successful proffesional career in their field.</p> <p>At this moment in Latvia, specific proffesion, including podologs, career management skill set is not defined. For students of podology learning of mentioned skills is indirectly integrated in educational process, which is reflected by the study program aims, methods and expected results.The aim of the article is to analyse career management skills identification problems in study process of podologs and in this regard, by empirical res…
Career practitioners' conceptions of competency for social media in career services
2014
This article reports findings from a phenomenographic investigation into career practitioners' understanding of competency for social media in career services. Sixteen Danish and Finnish practitioners with experience using social media in career services were interviewed in focus groups. Competency for social media in career services was conceived as (i) an ability to use social media for delivering information, (ii) an ability to use social media for delivering career services, (iii) an ability to utilise social media for collaborative career exploration and (iv) an ability to utilise social media for co-careering. The findings can be used to develop pre-service and in-service training of …
