Integrability and cycles of deformed N=2 gauge theory
To analyse pure N=2 SU(2) gauge theory in the Nekrasov-Shatashvili (NS) limit (or deformed Seiberg-Witten (SW)), we use the Ordinary Differential Equation/Integrable Model (ODE/IM) correspondence, and in particular its (broken) discrete symmetry in its extended version with two singular irregular points. Actually, this symmetry appears to be ‘manifestation’ of the spontaneously broken Z2 R-symmetry of the original gauge problem and the two deformed SW one-cycle periods are simply connected to the Baxter's T and Q functions, respectively, of the Liouville conformal field theory at the self-dual point. The liaison is realised via a second order differential operator which is essentially the ‘quantum’ version of the square of the SW differential. Moreover, the constraints imposed by the broken Z2 R-symmetry acting on the moduli space (Bilal-Ferrari equations) seem to have their quantum counterpart in the TQ and the T periodicity relations, and integrability yields also a useful Thermodynamic Bethe Ansatz (TBA) for the periods (Y(θ,±u) or their square roots, Q(θ,±u)). A latere, two efficient asymptotic expansion techniques are presented. Clearly, the whole construction is extendable to gauge theories with matter and/or higher rank groups
Proper packaging for food and no-food products to avoid injuries
OBJECTIVES:
This paper aims to present data on proper packaging for food and no-food products to avoid injuries.
METHODS:
Data collection was made from the Susy Safe data base and the results of the literature research.
RESULTS:
Fatal and near fatal foreign bodies injuries may occur at any age, however it is a particular problem for infants and young children due to a variety of predisposing factors. Safety packaging is therefore a landmark and a model for accident prevention.
CONCLUSIONS:
Taken the lack of researches and specificity on this subject, it is warmly suggested that a broader and deeper exploration, both at customer's and public health levels, has to be made, highlighting major risks and complications. Packaging classes are extremely composite, therefore accuracy in data registry must be achieved, since from a preventive point of view it is basilar not only knowing the nature of the foreign body but also having information on its origin
Foreign bodies inhalation as a research field: What can we learn from a bibliometric perspective over 30 years of literature?
Social support to elderly pacemaker patients improves device acceptance and quality of life
Introduction: Patient acceptance of cardiac device has been shown to limit their quality of life. Little is known about the impact of social support (SS) on pacemaker (PM) acceptance. The aim of the study is to investigate the level of device acceptance in patients with pacemaker (PM) in the short time and the role of SS related to patients' PM acceptance. Materials and methods: A total of 62 patients (median age: 76.50 years) seen in two cardiology clinic between June and November 2013 complete the Florida patient acceptance survey (FPAS), the Assessment of quality of life and related events (Aquarel Questionnaire), the Euro quality of life 5 dimension 3 level (EQ-5D-3L) and the Multidimensional scale of perceived social support (MSPSS) before PM implantation, after 7 days and after 30 days from PM implantation. Results: In 30 days, the levels of SS and of acceptance of cardiac device and of HRQoL increase. At 7 days, 16 patients have low level of acceptance of cardiac device, decreasing to 3 at 30 days. In particular, in short time patients with low level of FPAS have lower level of SS than patients with high level of acceptance of cardiac device (median of MSPSS total score: 4.75 vs. 5.58; P-value: 0.02). At multivariable analysis, social support is confirmed to influence device acceptance. Conclusions: The observed significant relationship between SS and patients' acceptance of PM suggests that SS is an important factor in promoting acceptance of cardiac device in patients with PM. © 2016 Published by Elsevier Masson SAS
