The One-Plaquette Model Limit of NC Gauge Theory in 2D

It is found that noncommutative U(1) gauge field on the fuzzy sphere S^2_N is equivalent in the quantum theory to a commutative 2-dimensional U(N) gauge field on a lattice with two plaquettes in the axial gauge A_1=0. This quantum equivalence holds in the fuzzy sphere-weak coupling phase in the limit of infinite mass of the scalar normal component of the gauge field. The doubling of plaquettes is a natural consequence of the model and it is reminiscent of the usual doubling of points in Connes standard model. In the continuum large N limit the plaquette variable W approaches the identity 1_{2N} and as a consequence the model reduces to a simple matrix model which can be easily solved. We compute the one-plaquette critical point and show that it agrees with the observed value \bar{\alpha}_*=3.35. We compute the quantum effective potential and the specific heat for U(1) gauge field on the fuzzy sphere S^2_{N} in the 1/N expansion using this one-plaquette model. In particular the specific heat per one degree of freedom was found to be equal to 1 in the fuzzy sphere-weak coupling phase of the gauge field which agrees with the observed value 1 seen in Monte Carlo simulation. This value of 1 comes precisely because we have 2 plaquettes approximating the NC U(1) gauge field on the fuzzy sphere.Comment: 46 pages,4 figures,typos corrected,references adde

Noncommutative QFT and Renormalization

Field theories on deformed spaces suffer from the IR/UV mixing and renormalization is generically spoiled. In work with R. Wulkenhaar, one of us realized a way to cure this disease by adding one more marginal operator. We review these ideas, show the application to $\phi^3$ models and use the heat kernel expansion methods for a scalar field theory coupled to an external gauge field on a $\theta$-deformed space and derive noncommutative gauge field actions.Comment: To appear in the proceedings of the Workshop "Noncommutative Geometry in Field and String Theory", Corfu, 2005 (Greece

How to Strengthen Patients' Meaning Response by an Ethical Informed Consent in Psychotherapy.

Healthcare professionals including psychotherapists are legally and ethically obliged to ensure informed consent for the provided treatments comprising type and duration or potential benefits and possible risks (e.g., side effects) among others. In the present contribution, we argue that as potential benefit, informed consent can foster the patient's meaning response. Moerman's notion of the meaning response as the physiological or psychological effects of meaning in the course and treatment of an illness is a useful concept in explaining the effects of communicating a treatment rationale as part of the informed consent procedure. The more compelling the rational explanation of the targeted treatment effects including an explanatory model and a model of unique and common change mechanisms, the stronger the meaning response is expected to be resulting in increased hope and positive expectations with regard to the treatment

Interactions of International Pilots\u27 Stress, Fatigue, Symptoms of Depression, Anxiety, Common Mental Disorders and Wellbeing

Objective This study Investigates more dimensions than previous studies simultaneously: pilots’ duty rosters, stress, sleep difficulties, fatigue levels, wellbeing, symptoms of depression, anxiety, and common mental disorders (CMD), and how they are interrelated. Background Several scientific studies have confirmed that fatigue can pose a significant risk to flight safety. Other studies reported positive depression screening results for more pilots, compared with the general population. Method A cross-sectional online survey was completed by 406 international pilots, who reported their duty rosters of the last two months. Pilots also self-assessed their stress-levels, sleep problems, fatigue, wellbeing, and mental health. Results Although pilots were on average rostered for only 60% of maximum legal duty and flight hours, three out of four pilots (76%) reported severe or high fatigue. Every fourth pilot reported considerable sleep difficulties (24%). 18.7% pilots reported positive depression screening results, 8.5% positive anxiety screenings, 7.2% reported significant symptoms of depression and anxiety. Highly significant to high correlations between stress, sleep problems, fatigue, symptoms of depression, anxiety, CMD and well-being were found. Conclusions Chronic stress appears to be linked to psychophysiological wear and tear, and was associated with higher levels of fatigue, more sleep disturbances and more impaired mental health. Future research should not only consider fatigue as an immediate threat to aviation safety, but also as a significant threat to pilots’ safety-relevant fitness to fly

Personal benefits of older adults engaging in a participatory action research (PAR) project

Participatory action research (PAR) is the process of conducting research with people rather than for them and is perceived as an empowering activity for older adults who participate in it. However, there is little evidence that outlines and explains the reasons why older adults engage in PAR. Thus, the aim of this study was to better understand the personal benefits for older adults participating in PAR. We based our study on the experiences of four older adults who volunteered for CareComLabs, a Swiss-based PAR project, for more than two years. A constructivist grounded theory design was used to explore the benefits of participating in CareComLabs by conducting in-depth, semi-structured interviews. The analysis yielded four categories of personal benefits of participating in CareComLabs: (a) enriching relationships; (b) broadening horizons for older age; (c) keeping in touch with one's profession; and (d) interacting in a nurturing community. Our findings may have implications for policies and frameworks focused on the identification of the potential of participatory action research as a community resource

Experimental program QUENCH at KIT on core degradation during reflooding under LOCA conditions and in the early phase of a severe accident

The most important accident management measure to terminate a severe accident transient in LWR is the injection of water to cool the uncovered degraded core. In order to detailed investigation of the reflood effect on bundle degradation the QUENCH program was initiated in 1996 followed-up the CORA bundle tests and is still on-going. So far, 17 integral bundle QUENCH experiments with 21–31 electrically heated fuel rod simulators of 2.5 m length using zirconia as fuel substitute have been conducted. Influence of following parameters on bundle degradation were investigated: degree of pre-oxidation, temperature at reflood initiation, flooding rate, effect of neutron absorber materials (B4C, Ag-In-Cd), air ingress, influence of the type of cladding alloy, formation of a debris bed in the core. Integral bundle experiments are supported by separate-effects tests. The program provides experimental data for the development of quench-related models and for the validation of SFD code systems. In seven tests, reflooding of the bundle led to a temporary temperature excursion. Considerable formation, relocation, and oxidation of melt were observed in all tests with escalation. The temperature boundary between rapid cool down and temperature escalation was typically 2100–2200 K in tests without absorber. Tests with absorber led to temperature escalations at lower temperatures. Although separate-effects tests have shown some differences in oxidation kinetics of advanced cladding materials, the influence of the various cladding alloys on the integral bundle behaviour during oxidation and reflooding was only limited. The two bundle tests with air ingress phase confirmed the strong effect of air on core degradation especially when pre-oxidation in steam is limited and oxygen starvation occurs during the air ingress phase. Oxidation in a nitrogen-containing atmosphere accelerates the kinetics by the temporary formation of zirconium nitride and causes strongly degraded and non-protective oxide scales. The latest QUENCH-LOCA tests investigated influence of secondary hydriding of ruptured cladding on mechanical properties of cladding tubes
