description: We discuss a device --- a purely capacitively coupled interacting spinless triple quantum dot system --- for the observation of the SU(3) Kondo effect. Unlike more familiar SU(2) and SU(4) Kondo effects in quantum dot devices which lead to unitary linear conductance at low temperatures, the SU(3) Kondo scenario can be easily identified by the conductance pinned to a characteristic value of 3/4 of the unitary limit. This is associated with the interesting fact that the SU(3) Kondo effect does not occur at the particle-hole symmetric point, where the system is found instead in the valence-fluctuating regime with the total dot occupancy flipping between 1 and 2, but for gate voltages in the two Kondo plateaux where the dot occupancy is pinned to an integer value, either 1 or 2. From the thermodynamic analysis in the Kondo regime we find that the effective impurity orbital moment, defined through the impurity orbital susceptibility (chi_imp) multiplied by the temperature, is Tχ_imp=1 at high temperatures and then it increases to the characteristic value of Tχ_imp=4/3 corresponding to the three-fold degenerate local-moment fixed point where the impurity entropy is S_imp=ln 3. Then, at much lower temperatures, the system flows to the non-degenerate strong-coupling fixed point in which the SU(3) Kondo effect takes place. We also report results about the robustness of the SU(3) Kondo effect against various perturbations present in real experimental setups. Finally, we describe possible mechanisms to restore the SU(3) Kondo physics by properly tuning the on-site dot potentials. We briefly comment on the spinfull case which has very different behavior and shows Kondo plateaus in conductance for all integer values of the occupancy, including at the particle-hole symmetric point.

description: The rotational spectra of two isotopologues (CF3(35)Cl-CO and CF3(37)Cl-CO) of the CF3Cl-CO adduct have been investigated and analyzed using supersonic-jet Fourier transform microwave spectroscopy, and found to have the features of a symmetric top. Rotational, centrifugal distortion, and nuclear quadrupole ((35)Cl and (37)Cl) coupling constants have been precisely obtained from high-resolution measurements. The two subunits of the complex are held together via a ClC halogen bond interaction. Information on the internal dynamics and the dissociation energy of the complex is provided.

description: Simultaneous recordings from multiple neural units allow us to investigate the activity of very large neural ensembles. To understand how large ensembles of neurons process sensory information, it is necessary to develop suitable statistical models to describe the response variability of the recorded spike trains. Using the information geometry framework, it is possible to estimate higher-order correlations by assigning one interaction parameter to each degree of correlation, leading to a $(2^N-1)$-dimensional model for a population with $N$ neurons. However, this model suffers greatly from a combinatorial explosion, and the number of parameters to be estimated from the available sample size constitutes the main intractability reason of this approach. To quantify the extent of higher than pairwise spike correlations in pools of multiunit activity, we use an information-geometric approach within the framework of the extended central limit theorem considering all possible contributions from high-order spike correlations. The identification of a deformation parameter allows us to provide a statistical characterisation of the amount of high-order correlations in the case of a very large neural ensemble, significantly reducing the number of parameters, avoiding the sampling problem, and inferring the underlying dynamical properties of the network within pools of multiunit neural activity.

description: Nichtadaptive zweidimensionale Prädiktoren für die DPCM-Codierung von Fernsehsignalen führenbei Kanten in Bildern meistens zu großen Prädiktionsfehlern und sind deshalb ungünstig für konturreicheBilder. Ein neuer adaptiver Prädiktor wird vorgeschlagen, bei dem Bildbereiche mit geringenSignaländerungen und solche mit Konturen getrennt mit zugehörigen Prädiktoren verarbeitet werden. Die Güte des neuen Prädiktors wird mit bekannten nichtadaptiven und adaptiven Prädiktoren anhandvon Computersimulationen verglichen. Die Vergleiche basieren sowohl auf quantitativen Kriterien alsauch auf subjektiven Tests. Durch den vorgeschlagenen Prädiktionsalgorithmus wird speziell dieHäufigkeit großer Prädiktionsfehler bei konturreichen Bildern erheblich reduziert. Verglichen mitanderen Prädiktionsalgorithmen führt dies zu einer geringeren Übertragungsbitrate bei gleicherBildqualität. © 1982, Walter de Gruyter. Alle Rechte vorbehalten.

description: The thermal parameters of a SiGe microbolometer were calculated using numerical modeling. The calculated thermal conduction and thermal response time are in good agreement with the values found experimentally and range between 2x10$^-7$ and 7x10$^-8$ W/K and 1.5 and 4.5 ms, respectively. High sensitivity of microbolometer is achieved due to optimization of the thermal response time and thermal conduction by fitting the geometry of supporting heat-removing legs or by selection of a suitable material providing boundary thermal resistance higher than 8x10$^-3$ cm$^2$K/W at the SiGe interface.

The RARE model: a generalized approach to random relaxation processes in disordered systems

Year: 2012
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: This paper introduces and analyses a general statistical model, termed the RARE model, of random relaxation processes in disordered systems. The model considers excitations, that are randomly scattered around a reaction center in a general embedding space. The model's input quantities are the spatial scattering statistics of the excitations around the reaction center, and the chemical reaction rates between the excitations and the reaction center as a function of their mutual distance. The framework of the RARE model is robust, and a detailed stochastic analysis of the random relaxation processes is established. Analytic results regarding the duration and the range of the random relaxation processes, as well as the model's thermodynamic limit, are obtained in closed form. In particular, the case of power-law inputs, which turn out to yield stretched exponential relaxation patterns and asymptotically Paretian relaxation ranges, is addressed in detail.

description: The correlation between the frequencies of pressure oscillation ωosc and the rotor speed (frequencies of rotor rotation ωRR) under established rotating stall were determined by three methods: directly from the time diagram of the oscillation process, from the behavior diagram of parameters in space and time and from frequency characteristics. In total accordance with the Theory of Nonlinear Oscillation, by all methods of analysis, the links are in the form of integer ratios: ωosc / ωRR = 1:2 (for n/ nd= 0.6, where n - rotor speed in the experiment and nd- rotor speed from data-sheet) and ωosc / ωRR = 3:7 (for n/ nd = 0.8 and 0.95). The phases of parameter oscillations in the transverse cross-section are equal to the sensor angles in compressor stator. This is in agreement with the theoretical concept of single-cell configurations of rotating stall.

description: Background: Alexithymia is a psychological construct characterized by inability to express emotions, poor imagination and operational thinking. It is well known its association with several chronic disease such as Diabetes type 2, little is known about diabetes type 1. We examined the association of alexithymia with clinical and psychological outcomes in subjects with type 1 diabetes. Methods: The study was conducted in a single diabetes center. The patients fully completed a protocol composed of the following instruments: the Toronto Alexithymia Scale-20 (TAS-20), the State-Trait Anger Expression Inventory-2 (STAXI-2), the State-Trait Anxiety Inventory form Y (STAI-Y), and the Hamilton Rating Scale for Depression (HAMD). TAS-20 scores were subdivided into tertiles, Correlations and two linear regression analyses, adjusted for only clinical and clinical plus psychological characteristics, were performed. Overall, 75 patients were enrolled (mean age 41.0±11.4 years, diabetes duration 19.9±11.9 years, 49.3% males, 30.7% treated with CSII). Results: People with diabetes of the upper TAS-20 tertile had the greatest rate of depression (with the highest degree of severity) and the higher levels of anger and anxiety. There was a significant correlation between TAS-20 scores with BMI (r=0.26; p=0.03), HAMD (r=0.38; p=0.001), STAXI-2 (r=0.34; p=0.003) and STAI-Y (r=0.48; p0.0001). Further regression analysis showed TAS-20 scores were associated with BMI (beta=0.29; p=0.02). The association with BMI was confirmed (beta=0.28; p=0.007) when psychological variables are considered; furthermore, a strong association with STAI-2 (beta=0.48; p0.0001) was detected, while the analysis did reveal any significant correlation between alexithymia and HbA1c levels. Conclusions: Alexithymia is strongly associated both with clinical and psychological characteristics, notably with BMI and anxiety traits. People with diabetes type 1 should be assessed for alexithymia. Future studies on the current topic are therefore required in order to elucidate the role of alexithymia in diabetes type 1. We believe that patients with diabetes and alexithymia could take advantage of psychological counseling.

description: Today literary criticism contests the 'Volksbuch' as a genre since its criteria seem under-defined. This paper aims, from a functional point of view, to explain its historical success by tracing four histories of this genre. The underdefinition of the genre turns out as the precondition of its manifold employments. What the different histories have in common is the imagination of the 'Volksbuch', which could unify the German nation. The 'Volksbuch', the paper will argue, is a virtual modern genre which imagines an anti-modern state of society and literature.

description: This article presents a comparative analysis of solar activity data, Mt Wilson diameter data, Super-Kamiokande solar neutrino data, and nuclear decay data acquired at the Lomonosov Moscow State University (LMSU). We propose that salient periodicities in all of these datasets may be attributed to r-mode oscillations. Periodicities in the solar activity data and in Super-Kamiokande solar neutrino data may be attributed to r-mode oscillations in the known tachocline, with normalized radius in the range 0.66 to 0.74, where the sidereal rotation rate is in the range 13.7 to 14.6 year-1. We propose that periodicities in the Mt Wilson and LMSU data may be attributed to similar r-mode oscillations where the sidereal rotation rate is approximately which we attribute to a hypothetical inner tachocline separating a slowly rotating core from the radiative zone. We also discuss the possible role of the RSFP (Resonant Spin Flavor Precession) process, which leads to estimates of the neutrino magnetic moment and of the magnetic field strength in or near the solar core.

description: We show that, for f any uniformly continuous (UC) complex-valued function on real Euclidean n-space ℝn, the heat flow f˜(t) is Lipschitz for all t > 0 and f˜(t) converges uniformly to f as t → 0. Analogously, let Ω be any irreducible bounded symmetric (Cartan) domain in complex n-space ℂn and consider the Bergman metric β(·,·) on Ω. For f any β-uniformly continuous function Ω, we show that there is a Berezin-Harish-Chandra flow of real analytic functions Bλf which is β-Lipschitz for each λ ≥ p (p, the genus of Ω) and Bλf converges uniformly to f as λ → ∞. For a certain subspace of UC we obtain stronger approximation results and we study the asymptotic behaviour of the Lipschitz constants. © 2015 by De Gruyter.

description: Introduction: Fibromyalgia is a very heterogeneous disorder. This heterogeneity is one of the reasons why researchers have tried to analyze different patient profiles and their relationship with quality of life. The aim of the present study was to identify: (1) latent profiles based on the Revised Fibromyalgia Impact Questionnaire’s scores, and (2) possible differences between them in quality of life, distrust in healthcare system, and adherence to medical recommendations. Methods: 707 FM patients (aged 18-85 years, 95% women) completed the Revised Fibromyalgia Impact Questionnaire, the 12-Item Short Form Health Survey, the Patient Adherence Scale, and the Health Care System Distrust Scale. Data were analyzed using latent profile analysis. Results: Three profiles were identified: (1) Low fibromyalgia impact profile (2) Moderate fibromyalgia impact profile, and (3) High fibromyalgia impact profile. Significant differences between these profiles were found in quality of life, adherence to medical recommendations, and distrust in healthcare system. Poor-sleep quality emerged as a significant high important symptom in the three profiles. Conclusion: The greater the fibromyalgia impact, the lower the quality of life, and the adherence to medical recommendations and the greater the mistrust in the healthcare system. Self-perceived sleep quality in fibromyalgia patients should require special attention from clinicians.

description: Symbiotic binaries are comprised of nebulae, whose densest portions have electron concentrations of 1E+8 - 1E+12 cm-3 and extend to a few AU. They are optically thick enough to cause a measurable effect of the scattering of photons on free electrons. In this paper we introduce modelling the extended wings of strong emission lines by the electron scattering with the aim to determine the electron optical depth, tau(e) and temperature, T(e), of symbiotic nebulae. We applied our profile-fitting analysis to the broad wings of the OVI 1032, 1038 A doublet and HeII 1640 A emission line, measured in the spectra of symbiotic stars AG Dra, Z And and V1016 Cyg. Synthetic profiles fit well the observed wings. By this way we determined tau(e) and T(e) of the layer of electrons, throughout which the line photons are transferred. During quiescent phases, the mean tau(e) = 0.056 +/- 0.006 and T(e) = 19 200 +/- 2 300 K, while during active phases, mean quantities of both parameters increased to tau(e) = 0.64 +/- 0.11 and T(e) = 32 300 +/- 2 000 K. During quiescent phases, the faint electron-scattering wings are caused mainly by free electrons from/around the accretion disk and the ionized wind from the hot star with the total column density, N(e)

description: The discovery of extensive air showers by Rossi, Schmeiser, Bothe, Kolhörster and Auger at the end of the 1930s, facilitated by the coincidence technique of Bothe and Rossi, led to fundamental contributions in the field of cosmic ray physics and laid the foundation for high-energy particle physics. Soon after World War II a cosmic ray group at MIT in the USA pioneered detailed investigations of air shower phenomena and their experimental skill laid the foundation for many of the methods and much of the instrumentation used today. Soon interests focussed on the highest energies requiring much larger detectors to be operated. The first detection of air fluorescence light by Japanese and US groups in the early 1970s marked an important experimental breakthrough towards this end as it allowed huge volumes of atmosphere to be monitored by optical telescopes. Radio observations of air showers, pioneered in the 1960s, are presently experiencing a renaissance and may revolutionise the field again. In the last 7 decades the research has seen many ups but also a few downs. However, the example of the Cygnus X-3 story demonstrated that even non-confirmable observations can have a huge impact by boosting new instrumentation to make discoveries and shape an entire scientific community.

description: Background: Work ability consists in the balance between employee’s capabilities and work demands. It can be measured by the Work Ability Index, a validated questionnaire that has been used in Europe since 1980s. This study is the first evaluating work ability among dock workers, a workforce which carries out complex activities requiring physical and mental engagement (night shifts, irregular shifts, constant demand for attention and concentration and significant physical effort). Objective: It was hypothized that the high strain level affecting this peculiar job may lead to a decrease in work ability. The aim of the study was to assess work ability and investigate if and how much not work-related factors, such as psycho-emotional state, lifestyle, health conditions and socio-demographic aspects, can interfere with it. Psycho-diagnostic protocol consisted of 6 questionnaires, chosen because of fast and effective data collection aiming to worker compliance and simple interpretation of results. Method: A total of 105 workers was engaged in different companies involved in port services. A protocol consisting of 6 questionnaires has been applied individually before the work shift: Work Ability Index (WAI), Effort-reward imbalance questionnaire (ERI), Beck Depression Inventory-II (BDI-II), Hamilton Rating Scale for Anxiety (HAM-A), Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI). Results: Work ability resulted excellent in 60 subjects and good in 37. No significant correlation between individual characteristics and work ability was found. Our results indicated that work ability was negatively related with emotional states, particularly with anxiety. Univariate and multivariate linear regression model for work ability, have shown a statistically significant correlation with BDI, HAM-A and ERI questionnaires’ results. Conclusion: Our results showed that WAI is a useful tool for routine occupational health surveillance. The association of work ability with psychosocial factors suggests that actions at the workplace adopted by occupational physicians in order to prevent a reduction in working capacity, should have a multidimensional approach evaluating not only individual lifestyle, but also mood states.

description: Context. Most observational studies so far point towards brown dwarfs sharing a similar formation mechanism as the one accepted for low mass stars. However, larger databases and more systematic studies are needed before strong conclusions can be reached. Aims. In this second paper of a series devoted to the study of the spectroscopic properties of the members of the Lambda Orionis Star Forming Region, we study accretion, activity and rotation for a wide set of spectroscopically confirmed members of the central star cluster Collinder 69 to draw analogies and/or differences between the brown dwarf and stellar populations of this cluster. Moreover, we present comparisons with other star forming regions of similar and different ages to address environmental effects on our conclusions. Methods. We study prominent photospheric lines to derive rotational velocities and emission lines to distinguish between accretion processes and chromospheric activity. In addition, we include information about disk presence and X-ray emission. Results. We report very large differences in the disk fractions of low mass stars and brown dwarfs (~58%) when compared to higher mass stars (26+4-3%) with 0.6 Msun being the critical mass we find for this dichotomy. As a byproduct, we address the implications of the spatial distribution of disk and diskless members in the formation scenario of the cluster itself. We have used the Halpha emission to discriminate among accreting and non-accreting sources finding that 38+8-7% of sources harboring disks undergo active accretion and that his percentage stays similar in the substellar regime. For those sources we have estimated accretion rates. Finally, regarding rotational velocities, we find a high dispersion in vsin(i) which is even larger among the diskless population.

We treat the inverse problem: Given an influence vector and a power index, determine a weighted voting game such that the distribution of influence among the voters is as close as possible to the given target value. We present exact algorithms and computational results for the Shapley-Shubik and the (normalized) Banzhaf power index.

description: Adolescence represents a developmental phase characterized by several changes during which social and cognitive advances lead adolescents to the progressive improvement of mental states talk (MST), namely as a specific kind of language marked by semantic terms describing internal mental states related to both self and others. The use of MST within individual narratives has been associated with the capability to reflect on cognitive and emotional experiences, thus promoting a meaning-making process of self and others understanding. In light of that and considering the additional challenges characterizing the adolescent transition for adoption, this qualitative exploratory contribution aims to explore adopted adolescents’ use of MST from their narratives deepening the meaning-making process of the psychological and relational dimension of self and others. The Friends and Family Interview was administered to 13 adopted adolescents after eight years from their first placement. The transcripts were analyzed through the use of thematic content analysis. The findings highlight the extensive employment of MST among adopted adolescents with broader use of the Self than the Other-oriented once. Self MST co-occurs with other categories related to significant relational contexts. This brings additional insights within adoption research providing valuable resources for working with adopted adolescents and their families.

Subjects: Vaccination Fear Scale; Vaccines; Hesitance; Psychometric properties; Validity and Reliability.

description: Background: The present study presents a first psychometric analysis of the Vaccination Fear Scale (VFS-6) developed to complement clinical efforts in the prevention of hesitance against vaccines. Methods: The sample comprised 2175 Spanish participants. The items of the VFS-6 were developed from validated Fear Coronavirus Scale (FCV-19S), which has several psychometric tests to ascertain its reliability and validity properties. Several psychometric tests were conducted to ascertain its reliability and validity properties. Results: After panel review and corrected item-total correlation test, six items with acceptable corrected item-total correlation were retained and then confirmed by significant and strong factor loadings. Exploratory and confirmatory factor analysis supported a bifactorial model (cognitive and physical factors), with robust psychometric properties, good reliability and internal consistency. Our data indicate that fear of vaccination is much more consistently related to the intention to vaccinate than fear of the disease. Conclusion: The VFS-6 is valid and reliable to assess fear of vaccination among the Spanish population.

description: We write the Green function of the $d$-dimensional hypercubic lattice in a piecewise form covering the entire real frequency axis. Each piece is a single integral involving modified Bessel functions of the first and second kinds. The smoothness of the integrand allows both real and imaginary parts of the Green function to be computed quickly and accurately for any dimension $d$ and any real frequency, and the computational time scales only linearly with $d$.

description: Objectives: Eating Disorder symptoms are highly prevalent and persistent among university students, especially in societies that place high emphasis on body image and in countries where the weather conditions result in body revealing clothing such as Cyprus. The aim of this study is to investigate whether body image inflexibility moderates the relationship between weight concerns and eating disorder symptoms in a sample of Cypriot University students. Methodology: 440 students responded to a survey including measures of weight concerns, (WCS), body image inflexibility (BIIAAQ) and symptoms of eating disorders (EAT-26). Moderation analyses were conducted using the PROCESS Macro for SPSS. Results: The moderation model showed a significant interaction between weight concerns and body image inflexibility (95% CI .004 - .007). Discussion: Higher body image inflexibility seems to exacerbate the risk from weight concerns augmenting the experience of eating disorders symptoms. The findings suggest that interventions targeting body image inflexibility might help prevent and alleviate eating disorders symptoms.

description: Background: Disorder-specific cognitive-behavioural conceptual models of anxiety disorders have informed psychological interventions with adults, but not with adolescents. This study aims to clarify the applicability of the intolerance of uncertainty model to generalized anxiety disorder symptoms in young people and the moderating influence of gender and age on these relationships. Methods: Three hundred and twenty-six young people, aged 11 – 15 years, from three high schools in a semi-rural area in West Scotland, completed self-report measures relating to generalized anxiety disorder symptoms and cognitive variables of the intolerance of uncertainty model. Results: Intolerance of uncertainty and negative problem orientation were found to be predictive of generalized anxiety disorder symptoms; positive beliefs about worry and cognitive avoidance were found to be less important in the prediction of generalized anxiety disorder symptoms. Gender only moderated the relationship between positive beliefs about worry and generalized anxiety disorder symptoms; age did not act as a moderator. Conclusion: The model of intolerance of uncertainty seems to be helpful in understanding generalized anxiety in young people. Clinical considerations are discussed.

description: The article deals with the material and symbolic meaning of the tripod in ancient Greek culture. The first argument addresses the tripod in the Homeric Epics where it functions as the most important prize in athletic competitions, but also as a valuable gift in various other contexts. The second argument concerns the Delphic tripod as a symbol of the mantic qualities of Apollon and his priestess Pythia. While most scholars prefer to interpret the tripod as a symbol of interregional relationship, especially that of guest-friendship, this article will stress the connection between the tripod and the sphere of power and the economic exchange of pastures and livestock.

description: Increasing demands on high data rate mobile communications services will inevitably drive future broadband mobile communication systems toward achieving data transmission rates in excess of 100 Mbps. One of the promising technologies which can satisfy this demand on high data rate mobile communications services is the Orthogonal Frequency Division Multiplexing (OFDM) transmission technology which falls under the general category of multicarrier modulation systems. OFDM is a spectrally efficient modulation technique that can achieve high speed data transmission over multipath fading channels without the need for powerful equalization techniques. However the price paid for this high spectral efficiency and less intensive equalization is low power efficiency. OFDM signals are very sensitive to non-linear effects due to the high peak-to-average power ratio (PAPR), which leads to the power inefficiency in the RF section of the transmitter. This paper analyzes the relation between aperiodic autocorrelation of OFDM symbols and PAPR. The paper also gives a comparative study of PAPR reduction performance of various channel coding techniques for the OFDM signals. For our study we have considered Hamming codes, cyclic codes, convolution codes, Golay and Reed-Muller codes. The results show that each of the channel coding technique has a different PAPR reduction performance. Coding technique with the highest value of PAPR reduction has been identified along with an illustration on PAPR reduction performances with respect to each code.

description: Background: Eating Disorders (EDs) often co-occur with substance use contributing to increasing concern about the individual’s health; both the conditions share several core features such as the tendency to use maladaptive emotion regulation strategies. The present study investigated associations between trait emotional intelligence (Trait EI), alexithymia and EDs, namely dieting, bulimia and oral control, in a nonclinical sample of adults. Moreover, the relationships with substance use frequencies were also examined with the aim of exploring the links between personality emotional competence traits (trait EI and alexithymia) and different addictive risk behaviours (EDs and substance use) in adulthood. Methods: Data were collected from a convenience sample composed of 394 (312 women; between ages 18 and 65; mean age = 32.34; SD = 11.97) participants, through online administration of questionnaires assessing trait emotional intelligence (TEIQue-SF), eating problems (EAT-26), alexithymia (TAS-20) and frequency of substance use (in the last year). Results: The group that exceeds the cut-off for EDs (n = 58; 14.7 %) has significantly lower trait EI scores (in all dimensions) and higher alexithymia scores than the other group. Some differences between the two groups were found on frequencies of nicotine and diuretics use. Age and all trait EI factors were negatively associated with eating disorders and alexithymia. Weak inverse correlations have emerged between EI and frequencies of substance use (namely cocaine, amphetamines, alcohol and tobacco). Female gender, well-being and self-control factors of EI emerged as significant predictors of EDs in adulthood. Conclusions: Our results suggest the importance of targeting emotion dysregulation for EDs and substance use behaviours. Interventions aimed at promoting healthy lifestyles could benefit from trait EI enhancement efforts. Practitioners and health educators need to recognize the potential efficacy of including trait EI within gender specific interventions planned to address ED symptoms and addictive behaviours in general.
