Research on global mortality has exhaustively documented a Russian mortality paradox— the phenomenon of populations of Slavic descent in experiencing higher adult mortality despite higher socioeconomic status. This study exploits Kazakhstan’s relatively heterogeneous population and geographic diversity to study ethnic differences in cause-specific mortality. After controlling for contextual dif...

Sleep is crucial to the physiological and psychological development of youth. The implications of insufficient sleep on learning and school performance are well documented. However, adequate sleep often goes unmet due to a combination of biological, societal, and environmental factors, especially during adolescence. In the present review, the changes to adolescent sleep patterns, and its conseq...

Sir, Naevus comedonicus was first described by Kofmann in 1895 (1). It was arranged in groups or linear patterns along Blaschko’s line and located on the face, neck, upper arms, chest and abdomen. It has been well documented that naevus comedonicus occurs as a single entity but occasionally in association with other disorders. The objective of this study was to analyse the clinical and immunohi...

Design patterns document approved solutions for recurring design problems. Due to their vague description such patterns are widely applicable, but their application is error-prone. Since pattern applications are rarely documented, the originally intended design tends to deviate during software evolution. With my research I aim at explicitly modeling and validating pattern applications in design...

Software patterns are computing artifacts used to document knowledge that may be reused during software development process. There are several types of patterns, such as analysis, design, and architectural, among others. Design patterns are the most well known by designers, but many of them are described in books and scientific papers, a recurring way of documenting patterns that limits their r...

Experienced Petri net modelers model in terms of patterns, just like object-oriented programmers use the design patterns of Gamma et al. So far there is no any structured collection of patterns for Colored Petri Nets. We have empirically collected 34 patterns in Colored Petri Nets and documented them in the pattern format. The patterns focus on the interplay between data-flow and control-flow, ...

We present a RBAC policy engineering approach that supports administrators to specify RBAC policies with the help of experts’ knowledge, which is documented using the pattern paradigm. These patterns are formalised in Web Ontology Language (OWL) that enables machine interpretation of experts’ knowledge and reasoning about the RBAC policy. Thus, administrators could specify RBAC policies by choo...

The seesaw mechanism is introduced and some of its different realizations and applications are discussed. It is pointed out how they can be used to understand the bi-large mixing patterns among neutrinos in combination with the assumptions about high scale physics such as grand unification or quasidegeneracy of neutrino masses.

We examine the structure of the quaternion group Q8 and its possible application to the physics of flavor. We find that a Q8 family symmetry is suitable to explain the difference between quark and lepton mixing patterns. Distinctive phenomenological predictions are derived for the neutrino sector and the electroweak Higgs sector. We also show how the Q8 symmetry suppresses the effective operato...
