Perception and prevalence of behavioral risk factors: the lifestyle risk scale (LRS)  [PDF]
Beatrix Algurén, Rolf Weitkunat
Open Journal of Preventive Medicine (OJPM) , 2011, DOI: 10.4236/ojpm.2011.13019
Abstract: Objective: To develop a lifestyle risk scale (LRS) of health-related behaviors based on risk assessments of study participants. Method: By means of pairwise comparisons of assessed risks associated with tobacco, alcohol, obesity, fast-food, physical inactivity, and lack of sleep, each at four levels, 24 behaviors were ranked on a unidimensional risk scale. Results: Overall, use of tobacco was assigned the highest risk score (3.7), consumption of fast-food and lack of sleep the lowest (1.7, 1.6). Minor risk factors (lack of sleep and fast-food) were, at their highest levels, assigned similar risk values as major risk factors (tobacco, alcohol, obesity) at their lowest levels. Lifestyles of female participants were less hazardous than those of male participants, as measured with the LRS. In contrast, perception of behavioral health risks was more precise in men. Conclusions: The LRS provides a practical quantification to identify and compare groups with different risk behavior patterns as well as clusters of risky health behaviors in and across populations. It can also support the communication of behavioral health risks.
Changing Attitudes and New Demands in Preservation Training
Beatrix Kastaly
Liber Quarterly : The Journal of European Research Libraries , 1999,
Abstract: At first, library preservation meant binding and repairing books and somewhat later the restoration or conservation of single items joined bookbinding. Besides, the importance of protection against insects and mould was always emphasised. Changes tend towards a shifting of emphasis on evolving optimal circumstances for the storage and use of library documents and on eliminating the deteriorating factors from the various forms of use.

Innovation co-operation modes in Hungarian chemical industry
Beatrix Lanyi
Perspectives of Innovations, Economics and Business , 2009,
Abstract: Innovation is becoming a fundamental tool of competitiveness of firms and economies. It is especially relevant in research intensive branches. Chemical industry belongs to one of the most innovative branches in Hungary. As innovation requires significant financial and knowledge resources company co-operations are crucial in carrying out a successful innovation by minimizing the costs and risks in the process. With the increasing number of collaborations the types and modes of co-operations are proliferating as well.

Nonlocality and entanglement in a strange system
Beatrix C. Hiesmayr
Physics , 2006, DOI: 10.1140/epjc/s10052-006-0199-x
Abstract: We show that the relation between nonlocality and entanglement is subtler than one naively expects. In order to do this we consider the neutral kaon system--which is oscillating in time (particle--antiparticle mixing) and decaying--and describe it as an open quantum system. We consider a Bell--CHSH inequality and show a novel violation for non--maximally entangled states. Considering the change of purity and entanglement in time we find that, despite the fact that only two degrees of freedom at a certain time can be measured, the neutral kaon system does not behave like a bipartite qubit system.
Bringing Bell's theorem back to the domain of Particle Physics & Cosmology
Beatrix C. Hiesmayr
Physics , 2015,
Abstract: John St. Bell was a physicist working most of his time at CERN and contributing intensively and sustainably to the development of Particle Physics and Collider Physics. As a hobby he worked on so-called "foundations of quantum theory", that was that time very unpopular, even considered to be scientifically taboo. His 1964-theorem, showing that predictions of local realistic theories are different to those of quantum theory, initiated a new field in quantum physics: quantum information theory. The violation of Bell's theorem, for instance, is a necessary and sufficient criterion for generating a secure key for cryptography at two distant locations. This contribution shows how Bell's theorem can be brought to the realm of high energy physics and presents the first conclusive experimental feasible test for weakly decaying neutral mesons on the market. Strong experimental and theoretical limitations make a Bell test in weakly decaying systems such as mesons and hyperons very challenging, however, these systems show an unexpected and puzzling relation to another big open question: why is our Universe dominated by matter, why did the antimatter slip off the map? This long outstanding problem becomes a new perspective via the very idea behind quantum information.
Not all brains are created equal: the relevance of individual differences in responsiveness to transcranial electrical stimulation
Beatrix Krause,Roi Cohen Kadosh
Frontiers in Systems Neuroscience , 2014, DOI: 10.3389/fnsys.2014.00025
Abstract: A current issue in the research of augmentation of brain functions using transcranial electrical stimulation (tES) is the diversity and inconsistency in outcome results. Similar studies often report different results, depending on the parameters and tasks used. Such inconsistencies have led to significant doubts about the efficacy of the method in the broader scientific community, despite its promising potential for patient recovery and treatment. Evidence on the large variability in individual cortical excitability and response to tES suggests that stimulation may affect individuals differently, depending on the subject’s age, gender, brain state, hormonal levels, and pre-existing regional excitability. Certain factors might even lead to the reversal of polarity-dependent effects, and therefore have crucial implications for neurorehabilitation and cognitive enhancement. Research paradigms may have to be refined in the future to avoid the confounding effects of such factors.
Multipartite entanglement measure for all discrete systems
Beatrix C. Hiesmayr,Marcus Huber
Physics , 2007, DOI: 10.1103/PhysRevA.78.012342
Abstract: Via a multidimensional complementarity relation we derive a novel operational entanglement measure for any discrete quantum system, i.e. for any multidimensional and multipartite system. This new measure admits a separation into different classes of entanglement obtained by using a flip operator 2,3,...,n times, defining a m-flip concurrence. For mixed states bounds on this m-flip concurrence can be obtained. Moreover, the information content of a n partite multidimensional system admits an intuitive interpretation. Explicitly, the three qubits system is analyzed and the physical difference in entanglement of the W-state, the GHZ state or the bi-separable state is revealed.
