description: Quantized single-electron transport driven by surface acoustic waves (SAW) through a pinched-off narrow constriction is studied theoretically. Long-range Coulomb interaction causes the tunneling coupling between the two-dimensional electron gas (2DEG) and the moving minimum of the SAW-induced potential to decay rapidly with time. The energy scale, associated with the characteristic time of this decay, controls both the width of the transition regions between the plateaus and the slope of the plateaus. This sets a limit for the accuracy of the quantization of acoustoelectric current at low temperature.

description: Purpose: In 2011, physiotherapists in Alberta, Canada were authorised to refer for diagnostic imaging (DI). To date, referral patterns for DI undertaken within Alberta’s public health system by authorised physiotherapists have not been described. Methods: Descriptive study of all physiotherapist-referred publicly funded DI studies undertaken between January 2012 and December 2016 in Alberta, Canada. Data included: number of imaging studies/therapist/month, imaging modality, geographical region and body part. Descriptive statistics summarised studies across year, modality, region and body part. Yearly rates (exact 95% confidence interval) were calculated across modality and region. Results: Over the study period, 20,280 DI studies were conducted. The majority (94.1%) were performed at community imaging clinics, with the remaining 5.9% undertaken at hospitals and public health centres. X-ray (76.4%) was most common followed by ultrasound imaging (USI) (19.7%) and magnetic resonance imaging (MRI) (3.5%). Regional variation was observed with one urban centre accounting for 76.7% of studies. The annual number per physiotherapist was 31.4 referrals/year (95% CI 24.8, 38.0). The majority (99.95%) were of the musculoskeletal system including: spine (21.7%), knee (15.5%) and sacroiliac joint (12.0%) radiography. Conclusions: Physiotherapists typically request plain X-ray and USI of the musculoskeletal system, with less use of MRI.

description: A series of new class of diethyl N-2-hydroxyethyl-N'-substituted phosphoramidimidates 6(a–e) and diethyl P-morpholino-N-substituted phosphonimidates 6(f–j) was synthesized. The precursor intermediates, diethyl substituted phosphoramidites 3(a–b) were prepared initially by a reaction of various amines 1(a–b) and diethyl phosphorochloridite (2) and then they were treated by in situ with aromatic/alkyl azides through Staudinger reaction to accomplish title products. Structures of all the synthesized compounds were characterized by spectroscopic data such as IR, NMR (1H, 13C, 31P), mass, and elemental analyses. The synthesized compounds were screened for their in vitro antimicrobial activity to understand their biological potency. The biological screening results disclosed that compounds 6b, 6c, 6e, 6g, 6h and 6j having potent antimicrobial activity against all the tested pathogens.

description: Superconductivity induced structures in the electronic Raman spectra of high-Tc superconductors are computed using the results of ab initio LDA-LMTO three-dimensional band structure calculations via numerical integrations of the mass fluctuations, either in the whole 3D Brillouin zone or limiting the integrations to the Fermi surface. The results of both calculations are rather similar, the Brillouin zone integration yielding additional weak structures related to the extended van Hove singularities. Similar calculations have been performed for the normal state of these high-Tc cuprates. Polarization configurations have been investigated and the results have been compared to experimental spectra. The assumption of a simple d_(x^2-y^2)-like gap function allows us to explain a number of experimental features but is hard to reconcile with the relative positions of the A1g and B1g peaks.

description: We present analytic approximations for the field, temperature, and orientation dependences of the interface velocity in a two-dimensional kinetic Ising model in a nonzero field. The model, which has nonconserved order parameter, is useful for ferromagnets, ferroelectrics, and other systems undergoing order-disorder phase transformations driven by a bulk free-energy difference. The Solid-on-Solid (SOS) approximation for the microscopic surface structure is used to estimate mean spin-class populations, from which the mean interface velocity can be obtained for any specific single-spin-flip dynamic. This linear-response approximation remains accurate for higher temperatures than the single-step and polynuclear growth models, while it reduces to these in the appropriate low-temperature limits. The equilibrium SOS approximation is generalized by mean-field arguments to obtain field-dependent class populations for moving interfaces, and thereby a nonlinear-response approximation for the velocity. The analytic results are compared with Monte Carlo simulations. Excellent agreement is found in a wide range of field, temperature, and interface orientation.

description: The United Nations has committed to halving food waste by 2030. In line with this goal, companies have started rescuing some foods that would otherwise be discarded and communicating it to their customers. These foods are repurposed as ingredients and marketed as upcycled or rescued. Notably, upcycled products (e.g., ice cream) can be made with rescued ingredients that are familiar (e.g., chocolate) or unfamiliar (e.g., malted milk) to consumers, which might affect how they are perceived. This research aims to investigate the impact of informing consumers about the “rescued” nature of ingredients. It also assesses how consumers' familiarity with these rescued ingredients moderates the effect on product perception and consumer behavior. We find that adding a “rescued” claim enhances a product's perceived sustainability and healthiness, positively influencing consumers' purchase intention. No significant effect of the claim on expected taste was observed. The effects of the claim on perceived sustainability and healthiness are more pronounced when consumers are already familiar with the rescued ingredient.

description: Discovered in 2003 the mayenite electride (Ca12Al14O33–x(2e–)x) is the first electride being stable under ambient conditions. Different reaction conditions are known to result in samples with strongly deviating electron contents x. Various methods for determining x have been applied but have individual disadvantages. Therefore, a new alternative approach based on the reduction of dichromate and its photometric quantification is introduced and evaluated in this paper. For this, mayenite oxide was synthesised via classical solid-state synthesis and afterwards reduced by heating pellets embedded in the respective reducing agents under dynamic vacuum. Using carbon, titanium and zirconium as oxygen getters, different degrees of reduction were achieved. The electron densities of the obtained electrides were determined using iodometric titration, conductivity measurements and the new dichromate based photometry. Our results show that the latter method is feasible, robust and leads to well-reproducible, reliable values.

description: Die Arbeitszufriedenheitsforschung weist verschiedene Unzulänglichkeiten auf: Die zur Messung eingesetzten Fragebögen wurden in der Regel nicht theoriegeleitet entwickelt. Zahlreiche Forschungsergebnisse, die mit Hilfe dieser Fragebögen erzielt wurden, sind unplausibel. Theoretisch fundiertere Modelle beschränken sich auf kognitiv-motivationale Aspekte. Wenig diskutiert wurde bislang eine Erweiterung der Arbeitszufriedenheitsforschung durch emotionspsychologische Perspektiven. Nach einer Darstellung von Forschungsarbeiten über Emotionen in Arbeitssituationen wird eine explorative Studie zu subjektiven Vorstellungen "Betroffener" über emotionales Erleben von Arbeit beschrieben. In den durchgeführten Interviews zeigte sich nicht nur eine große Vielfalt von Emotionen. Deutlich wurde außerdem, daß intensive emotionale Arbeitserlebnisse sehr lange in Erinnerung bleiben. Es ließen sich auch erste Hinweise für die Annahme finden, daß persönlich bedeutsame emotionale Erlebnisse bei der Arbeit zu subjektiven Theorien "verarbeitet" werden.

On n’oublie point une personne comme vous et l’on est bien aise d’en apprendre de temps en temps des nouvelles. J’aurais déjà eu l’honneur de vous écrire si je n’avais été distrait moins par les embarras de l’impression que par les inquiétudes que me donne la lenteur des ouvriers. Depuis quatre mois, l’ouvrage est sous presse et il n’y en a pas encore la moitié de tiré. Enfin, on vient de me promettre d’une manière bien formelle qu’avant la fin de septembre le 2nd volume serait chez l’imprimeur. Je ne sais pas si je pourrais y faire entrer les quatre mémoires que je compte mettre à la fin de ce volume et si je ne serai pas obligé, pour ne pas les rendre trop gros, de renvoyer au troisième le mémoire sur les cliniques, les communes et les bourgeoisies de Provence, sujet qui m’a paru fort intéressant. Il me [fol. 107 v] tarde, Monsieur, de vous envoyer ce second monument de mes sentiments pour vous.
J’avais pris la liberté de vous demander les inscriptions du Dauphiné. Je souhaiterais bien, Monsieur, que vous eussiez la complaisance de les faire copier, par quelqu’un qui soit en état de faire correctement cette besogne et que je payerai, car c’est une des conditions que je vous prie de me laisser remplir. Je vous offre ici mes services en vous priant d’agréer les assurances du sincère et respectueux attachement avec lequel j’ai l’honneur d’être, Monsieur, votre très humble et très obéissant serviteur.

A Complete Leading-Order, Renormalization-Scheme-Consistent Calculation of Structure Functions

description: We present consistently ordered calculations of the structure functions F_2(x,Q^2) and F_L(x,Q^2), in different expansion schemes. After discussing the standard expansion in powers of alpha_s(Q^2) we consider a leading-order expansion in ln(1/x) and finally an expansion which is leading order in both ln(1/x) and alpha_s(Q^2), and which is the only really correct expansion scheme. Ordering the calculation in a renormalization-scheme-consistent manner, there is no factorization scheme dependence, and the calculational method naturally includes to the ``physical anomalous dimensions'' of Catani. However, it imposes stronger constraints than just the use of these effective anomalous dimensions. A relationship between the small-x forms of the inputs F_2(x,Q_I^2) and F_L(x,Q_I^2) is predicted. Analysis of a wide range of data for F_2(x,Q^2) is performed, and a very good global fit obtained, particularly for data at small x. The fit allows a prediction for F_L(x,Q^2) to be produced, which is smaller than those produced by the usual NLO-in-alpha_s(Q^2) fits to F_2(x,Q^2) and different in shape.

description: In the subcritical interval of the Reynolds number 4320\leq R\leq R_c\equiv 5772, the Navier--Stokes equations of the two--dimensional plane Poiseuille flow are approximated by a 22--dimensional Galerkin representation formed from eigenfunctions of the Orr--Sommerfeld equation. The resulting dynamical system is brought into a generalized normal form which is characterized by a disposable parameter controlling the magnitude of denominators of the normal form transformation. As rigorously proved, the generalized normal form decouples into a low--dimensional dominant and a slaved subsystem. {}From the dominant system the critical amplitude is calculated as a function of the Reynolds number. As compared with the Landau method, which works down to R=5300, the phase velocity of the critical mode agrees within 1 per cent; the critical amplitude is reproduced similarly well except close to the critical point, where the maximal error is about 16 per cent. We also examine boundary conditions which partly differ from the usual ones.

description: Trained machine learning models are increasingly used to perform high-impact tasks in areas such as law enforcement, medicine, education, and employment. In order to clarify the intended use cases of machine learning models and minimize their usage in contexts for which they are not well suited, we recommend that released models be accompanied by documentation detailing their performance characteristics. In this paper, we propose a framework that we call model cards, to encourage such transparent model reporting. Model cards are short documents accompanying trained machine learning models that provide benchmarked evaluation in a variety of conditions, such as across different cultural, demographic, or phenotypic groups (e.g., race, geographic location, sex, Fitzpatrick skin type) and intersectional groups (e.g., age and race, or sex and Fitzpatrick skin type) that are relevant to the intended application domains. Model cards also disclose the context in which models are intended to be used, details of the performance evaluation procedures, and other relevant information. While we focus primarily on human-centered machine learning models in the application fields of computer vision and natural language processing, this framework can be used to document any trained machine learning model. To solidify the concept, we provide cards for two supervised models: One trained to detect smiling faces in images, and one trained to detect toxic comments in text. We propose model cards as a step towards the responsible democratization of machine learning and related AI technology, increasing transparency into how well AI technology works. We hope this work encourages those releasing trained machine learning models to accompany model releases with similar detailed evaluation numbers and other relevant documentation.

The combination of recovery and reusability of catalyst, simple and applicable approach, good reaction time and good yields of products make this method as a suitable route for this purpose. The structures of the products were determined by FT-IR, 1H-, 13C- and 31P- Nuclear Magnetic Resonance spectroscopies, and elemental analysis.
Price Variations in a Stock Market With Many Agents

description: Large variations in stock prices happen with sufficient frequency to raise doubts about existing models, which all fail to account for non-Gaussian statistics. We construct simple models of a stock market, and argue that the large variations may be due to a crowd effect, where agents imitate each other's behavior. The variations over different time scales can be related to each other in a systematic way, similar to the Levy stable distribution proposed by Mandelbrot to describe real market indices. In the simplest, least realistic case, exact results for the statistics of the variations are derived by mapping onto a model of diffusing and annihilating particles, which has been solved by quantum field theory methods. When the agents imitate each other and respond to recent market volatility, different scaling behavior is obtained. In this case the statistics of price variations is consistent with empirical observations. The interplay between ``rational'' traders whose behavior is derived from fundamental analysis of the stock, including dividends, and ``noise traders'', whose behavior is governed solely by studying the market dynamics, is investigated. When the relative number of rational traders is small, ``bubbles'' often occur, where the market price moves outside the range justified by fundamental market analysis. When the number of rational traders is larger, the market price is generally locked within the price range they define.

Evidence for flat zero-energy bands in bilayer graphene with a periodic defect lattice

description: In this work, we perform ab initio calculations, based on the density functional theory, of the effects on the graphene bilayer when we intercalate carbon atoms between the layers. We use the unit cell of the bilayer to construct larger unit cells (supercells), positioning a single carbon atom in the hollow position between the monolayers and periodically replicating the supercell. By increasing the size of the unit cell and consequently, the periodicity of the inserted atoms, we are able to minimize the carbon-carbon interaction and therefore infer the changes in the electronic, vibrational and thermal behavior of the bilayer when the intercalated atoms do not interact with each other. The main result, concerning the electronic properties, is the appearance of a doubly degenerate flat band at the Fermi level. These states are interpreted as coming from the periodic deformation of the bilayer due to the inserted atoms. It acts as a non-Abelian flux network creating zero energy at bands as predicted by San-Jose, González and Guinea in 2012. Since the periodic strain field associated to the defect array has such a strong influence on the electronic properties of the bilayer, it may be useful for practical applications. For instance, it can act as frozen-in magnetic-like field flux tubes. All-carbon nanostructures can then be designed to have electronic behavior at different regions tailored by the chosen defect pattern.

description: This study aimed to investigate the potential of ultrasound (US), pulsed electric fields (PEF), and high pressure (HP) to produce cricket protein concentrates with functional properties suitable for the food industry. Protein concentrates were produced from Gryllus assimilis using these non-thermal technologies. The impacts of these technologies on the protein structure and functional properties of the protein concentrates were evaluated. US treatment reduced particle size by 33 %, increased negative surface charge by 59 %, and enhanced hydrophobicity by 29 %, leading to improved solubility, water retention (40 %), foam capacity (31 %) and stability. HP partially unfolded proteins and increased surface hydrophobicity by 10 %, improving oil-holding capacity (10 %) and gelation properties (17 %). PEF increased particle size by 26 %, which enhanced foam capacity (29 %) and stability.

description: Binary stars are common. While only those with small separations may exchange gas with one another, even the widest binaries interact with their gaseous surroundings. Drag forces and accretion rates dictate how these systems are transformed by these interactions. We perform three-dimensional hydrodynamic simulations of Bondi-Hoyle-Lyttleton flows, in which a binary moves supersonically relative to a homogeneous medium, using the adaptive mesh refinement code FLASH. We simulate a range of values of the initial semi-major axis of the orbit relative to the gravitational focusing impact parameter of the pair. When the binary separation is less than the gravitational focusing impact parameter, the pair orbits within a shared bow shock. When the pair is wider, each object has an individual bow-shock structure. The long-term evolution of the binary is determined by the timescales for accretion, slowing of the center of mass, and orbital inspiral. We find a clear hierarchy of these timescales; a binary's center-of-mass motion is slowed over a shorter timescale than the pair inspirals or accretes. In contrast to previous analytic predictions, which assume an unperturbed background medium, we find that the timescale for orbital inspiral is proportional to the semi-major axis to the $0.19 \pm 0.01$ power. This positive scaling indicates that gaseous drag forces can drive binaries either to coalescence or to the critical separation at which gravitational radiation dominates their further evolution. We discuss the implications of our results for binaries embedded in the interstellar medium, active galactic nuclei disks, and common envelope phases.

The evolution of a network of cosmic string loops

description: We set up and analyse a model for the non-equilibrium evolution of a network of cosmic strings initially containing only loops and no infinite strings. Due to this particular initial condition, our analytical approach differs significantly from existing ones. We describe the average properties of the network in terms of the distribution function n(l,t) dl, the average number of loops per unit volume with physical length between l and l + dl at time t. The dynamical processes which change the length of loops are then estimated and an equation, which we call the `rate equation', is derived for (dn/dt). In a non-expanding universe, the loops should reach the equilibrium distribution predicted by string statistical mechanics. Analysis of the rate equation gives results consistent with this. We then study the rate equation in an expanding universe and suggest that three different final states are possible for the evolving loop network, each of which may well be realised for some initial conditions. If the initial energy density in loops in the radiation era is low, then the loops rapidly disappear. For large initial energy densities, we expect that either infinite strings are formed or that the loops tend towards a scaling solution in the radiation era and then rapidly disappear in the matter era. Such a scenario may be relevant given recent work highlighting the problems with structure formation from the standard cosmic string scenario.

Nonlinear sigma model approach for phase disorder transitions and the pseudogap phase in chiral Gross-Neveu, Nambu-Jona-Lasinio models and strong-coupling superconductors

description: We briefly review the nonlinear sigma model approach for the subject of increasing interest: "two-step" phase transitions in the Gross-Neveu and the modified Nambu-Jona-Lasinio models at low $N$ and condensation from pseudogap phase in strong-coupling superconductors. Recent success in describing "Bose-type" superconductors that possess two characterstic temperatures and a pseudogap above $T_c$ is the development approximately comparable with the BCS theory. One can expect that it should have influence on high-energy physics, similar to impact of the BCS theory on this subject. Although first generalizations of this concept to particle physics were made recently, these results were not systematized. In this review we summarize this development and discuss similarities and differences of the appearence of the pseudogap phase in superconductors and the Gross-Neveu and Nambu-Jona-Lasinio - like models. We discuss its possible relevance for chiral phase transition in QCD and color superconductors. This paper is organized in three parts: in the first section we briefly review the separation of temperatures of pair formation and pair condensation in strong - coupling and low carrier density superconductors (i.e. the formation of the {\it pseudogap phase}). Second part is a review of nonlinear sigma model approach to an analogous phenomenon in the Chiral Gross-Neveu model at small N. In the third section we discuss the modified Nambu-Jona-Lasinio model where the chiral phase transition is accompanied by a formation of a phase analogous to the pseudogap phase.

Betriebliche Frauenförderung durch Weiterbildung

description: Entgegen der von der Regierung und den Arbeitgebern in der Öffentlichkeit verbreiteten Annahme, daß eine Aufwertung innerbetrieblicher Qualifizierung mit zunehmenden beruflichen Aufstiegsmöglichkeiten für Frauen einhergeht, kristallisiert sich die betriebliche Weiterbildung als Instrument der Reproduktion von Chancenungleichheit zwischen Männern und Frauen heraus. An die Stelle einer aktiven Gleichstellungspolitik durch die Vergabe notwendiger Qualifizierungschancen findet eine Remobilisierung traditioneller Legitimationsmuster für geschlechtsspezifische Ungleichheit im Beschäftigungssystem statt. Im folgenden Beitrag werden unter Rekurs auf bekannte empirische Ergebnisse diejenigen Schwierigkeiten rekonstruiert, mit denen gleichstellungspolitische Vorhaben durch betriebliche Weiterbildung zu kämpfen haben.

Trajectories in phase diagrams, growth processes and computational complexity: how search algorithms solve the 3-Satisfiability problem

description: Most decision and optimization problems encountered in practice fall into one of two categories with respect to any particular solving method or algorithm: either the problem is solved quickly (easy) or else demands an impractically long computational effort (hard). Recent investigations on model classes of problems have shown that some global parameters, such as the ratio between the constraints to be satisfied and the adjustable variables, are good predictors of problem hardness and, moreover, have an effect analogous to thermodynamical parameters, e.g. temperature, in predicting phases in condensed matter physics [Monasson et al., Nature 400 (1999) 133-137]. Here we show that changes in the values of such parameters can be tracked during a run of the algorithm defining a trajectory through the parameter space. Focusing on 3-Satisfiability, a recognized representative of hard problems, we analyze trajectories generated by search algorithms using growth processes statistical physics. These trajectories can cross well defined phases, corresponding to domains of easy or hard instances, and allow to successfully predict the times of resolution.

description: The coupling of vortices to phonons in a superfluid is a gauge coupling dictated by topology. The density and current response to a moving vortex are computed and contrasted with the standard backflow picture. Exploiting the analogy to (2+1)-dimensional electrodynamics, we compute the effective vortex mass $M(ω)$ and find it to be logarithmically divergent in the low frequency limit, leading to a super-Ohmic dissipation in response to an oscillating superflow. Numerical integration of the nonlinear Schroedinger equation supports these conclusions. Interaction of vortices and impurities is also discussed.

description: We have performed a photoemission study of Ti$_{4}$O$_{7}$ around its two transition temperatures so as to cover the metallic, high-temperature insulating (bipolaron-liquid), and low-temperature insulating (bipolaron-crystal) phases. While the spectra of the low-temperature insulating phase show a finite gap at the Fermi level, the spectra of the high-temperature insulating phase are gapless, which is interpreted as a soft Coulomb gap due to dynamical disorder. We suggest that the spectra of the high-temperature disordered phase of Fe$_{3}$O$_{4}$, which exhibits a charge order-disorder transition (Verwey transition), can be interpreted in terms of a Coulomb gap.

Nonequilibrium Kondo effect in a graphene-coupled quantum dot in the presence of a magnetic field

description: Quantum dots connected to larger systems containing a continuum of states like charge reservoirs allow the theoretical study of many-body effects such as the Coulomb blockade and the Kondo effect. Here, we analyze the nonequilibrium Kondo effect and transport phenomena in a quantum dot coupled to pure monolayer graphene electrodes under external magnetic fields for finite on-site Coulomb interaction. The system is described by the pseudogap Anderson Hamiltonian. We use the equation of motion technique to determine the retarded Green's function of the quantum dot. An analytical formula for the Kondo temperature is derived for electron and hole doping of the graphene leads. The Kondo temperature vanishes in the vicinity of the particle-hole symmetry point and at the Dirac point. In the case of particle-hole asymmetry, the Kondo temperature has a finite value even at the Dirac point. The influence of the on-site Coulomb interaction and the magnetic field on the transport properties of the system shows a tendency similar to the previous results obtained for quantum dots connected to metallic electrodes. Most remarkably, we find that the Kondo resonance does not show up in the density of states and in the differential conductance for zero chemical potential due to the linear energy dispersion of graphene. An analytical method to calculate self-energies is also developed which can be useful in the study of graphene-based systems. Our graphene-based quantum dot system provides a platform for potential applications of nanoelectronics. Furthermore, we also propose an experimental setup for performing measurements in order to verify our model.

Effective theory for real-time dynamics in hot gauge theories

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: For a high temperature non-Abelian plasma, we reformulate the hard thermal loop approximation as an effective classical thermal field theory for the soft modes. The effective theory is written in local Hamiltonian form, and the thermal partition function is explicitly constructed. It involves an ultraviolet cutoff which separates between hard and soft degrees of freedom in a gauge-invariant way, together with counterterms which cancel the cutoff dependence in the soft correlation functions. The effective theory is well suited for numerical studies of the non-perturbative dynamics in real time, in particular, for the computation of the baryon number violation rate at high temperature.
