description: Excerpts from the report Introduction: Previous studies indicate that refrigeration extends the keeping quality of cranberries. No published data, however, have been found on the aspect of continuous refrigeration; that is, starting at the time the cranberries are placed in storage and ending with the commodity on the retail shelf. The Massachusetts cranberry industry has expressed an interest in the possibility of using cold storage instead of common storage in the producing area. Accordingly, an integrated study was made of the continuous refrigeration of cranberries from the 1957 crop, involving their storage, followed by prepackaging, and their subsequent holding qualities.

description: The temperature-dependence of the magnetization near the surface of a band-ferromagnet is measured with monolayer resolution. The simultaneous application of novel highly surface-sensitive techniques enables one to deduce the layer-dependent magnetization curves at a Fe(100) surface. Analysis of data is based on a simple mean-field approach. Implications for modern theories of itinerant-electron ferromagnetism are discussed.

description: We show that two capacitively-coupled Josephson junctions, in the quantum limit, form a simple coupled qubit system with effective coupling controlled by the junction bias currents. We compute numerically the energy levels and wave functions for the system, and show how these may be tuned to make optimal qubits. The dependence of the energy levels on the parameters can be measured spectroscopically, providing an important experimental test for the presence of entangled multiqubit states in Josephson-junction based circuits.

description: We generate high-fidelity massively entangled states in an antiferromagnetic spin-1 Bose-Einstein condensate (BEC) by utilizing multilevel oscillations. Combining the multilevel oscillations with additional adiabatic drives, we greatly shorten the necessary evolution time and relax the requirement on the control accuracy of quadratic Zeeman splitting, from micro-Gauss to milli-Gauss, for a $^{23}$Na spinor BEC. The achieved high fidelities over $96\%$ show that two kinds of massively entangled states, the many-body singlet state and the twin-Fock state, are almost perfectly generated. The generalized spin squeezing parameter drops to a value far below the standard quantum limit even with the presence of atom number fluctuations and stray magnetic fields, illustrating the robustness of our protocol under real experimental conditions. The generated many-body entangled states can be employed to achieve the Heisenberg-limit quantum precision measurement and to attack nonclassical problems in quantum information science.

Non-adiabatic transitions through exceptional points in the band structure of a PT-symmetric lattice

description: Exceptional points, at which two or more eigenfunctions of a Hamiltonian coalesce, occur in non-Hermitian systems and lead to surprising physical effects. In particular, the behaviour of a system under parameter variation can differ significantly from the familiar Hermitian case in the presence of exceptional points. Here we analytically derive the probability of a non-adiabatic transition in a two-level system driven through two consecutive exceptional points at finite speed. The system is Hermitian far away from the exceptional points. In the adiabatic limit an equal redistribution between the states coalescing in the exceptional point is observed, which can be interpreted as a loss of information when passing through the exceptional point. For finite parameter variation this gets modified. We demonstrate how the transition through the exceptional points can be experimentally addressed in a PT-symmetric lattice using Bloch oscillations.

description: We present measurements of the Cabibbo-suppressed decays Lambda_c^+ --> Lambda0 K+ and Lambda_c^+ --> Sigma0 K+ (both first observations), Lambda_c^+ --> Sigma+ K+ pi- (seen with large statistics for the first time), Lambda_c^+ --> p K+ K- and Lambda_c^+ --> p phi (measured with improved accuracy). Improved branching ratio measurements for the decays Lambda_c^+ --> Sigma+ K+ K- and Lambda_c^+ --> Sigma+ phi, which are attributed to W-exchange diagrams, are shown. We also present the first evidence for Lambda_c^+ --> Xi(1690)^0 K+ and set an upper limit on the non-resonant decay Lambda_c^+ --> Sigma+ K+ K-. This analysis was performed using 32.6 fb^{-1} of data collected by the Belle detector at the asymmetric e+ e- collider KEKB.

description: We used a retrospective survey (N = 346) to model the patterns of appraisal, motivation, and coping that uniquely correspond with 12 positive emotions (affection/love, amusement, awe, challenge/determination, compassion, gratitude, happiness/joy, hope, interest, pride, relief, and serenity/tranquillity). Generally, we conceptually replicated previously demonstrated appraisal profiles of positive emotion while also examining how additional appraisals differentiate among positive emotions. We then uncovered the motivational goals and coping processes associated with each positive emotion. We discuss the implications of our findings for future research on positive emotion.
Effect of the additional second neighbor hopping on the charge dynamics in the t-J model

description: The effect of the additional second neighbor hopping t' on the charge dynamics of the t-J model in the underdoped regime is studied within the fermion-spin theory. The conductivity spectrum of the t-t'-J model shows the low-energy peak and unusual midinfrared band, while the resistivity exhibits a nearly temperature linear dependence with deviation at low temperature in the underdoped regime. Although the qualitative feature of the charge dynamics in the t-t'-J model is the same as in the case of the t-J model, the additional second neighbor hopping t' leads to a clear shift of the position of the midinfrared band to the higher energies in the conductivity spectrum, and suppress the range of the deviation from the temperature linear dependence in the resistivity.

Das Teilprojekt „Q-Master: Qualifizierung von Quereinsteiger*innen im Master of Education“ fokussiert auf das Thema des Quer- und Seiteneinstiegs für ausgewählte Mangelfächer wie z. B. Physik. Im Wintersemester 2016/17 startete dazu ein Modellversuch im Land Berlin. Das Projekt verfolgt das Ziel, die Quereinstiger*innen innerhalb eines viersemestrigen Master of Education ausreichend für den anschließenden Vorbereitungsdienst zu qualifizieren. Dabei soll ein adäquates Ausbildungsniveau im Vergleich zu regulären Lehramtsstudierenden erreicht werden. Ob dies gelingt, wird in der Begleitforschung und Evaluation des Studienganges untersucht. Hierbei liegt das Augenmerk auf der Entwicklung professioneller Kompetenzen von Lehrkräften. In einer ersten Erhebung wurden bei der ersten Studienkohorte (N=29) folgende Konstrukte erhoben: pädagogische Vorerfahrungen, Berufswahlmotive, Lehrer-Selbstwirksamkeitserwartung, Studienerfolg und soziodemografische Daten. Im Fach Physik werden die Q-Master Studierenden studienbegleitend zu Fachdidaktischem Wissen, Fachwissen und ihren Überzeugungen zum Lehrberuf und ihren Fächern befragt.

 Bonaparte indique que le spécimen qu’il décrit appartient à une nouvelle espèce, qu’il se trouve au MNHN et qu’il provient d’« Ins. Polynesiae ». Ce spécimen était monté mais son socle a disparu. Il fut démonté bien avant que cette opération ne soit généralisée à pratiquement tous les spécimens types dans les années 1970 à 1990. Cependant son numéro dans l’Ancien catalogue nous est resté connu car repris dans le Nouveau catalogue. D’après Hartert (1925), qui a étudié les sous-espèces de Trichoglossus haematodus, ce spécimen serait originaire du Vanuatu.

description: Despite of the increasing application of silica nanoparticles and identification of oral exposure as a major entry portal, we lack understanding of nanosilica effects in the gut. Thus, we investigated biointeractions of nanosilica with single intestinal cells. The invertebrate nematode Caenorhabditis elegans was chosen as model organism with a tractable intestine and realistic target organism of nanomaterials in the environment. We found that nanosilica impairs the intestinal uptake of oligopeptides. Downstream to absorption by the apical OPT-2/PEP-2 transporter dipeptides were trapped in aberrant vesicles that grow over time and reach diameters of ≥6 μm. The peptide vesicles do not correspond to known organelles such as gut granules and form independently of related gene products GLO-1 or GLO-3. Formation of aberrant peptide vesicles also occurred independently of insulin/IGF-I receptor (DAF-2) signaling and daf-2 loss of function mutants showed specific vesicle patterns including distinct localization along the apical membrane of single intestinal cells. As malnutrition of exposed C. elegans manifested in reduced growth and a petite phenotype similar to OPT-2/PEP-2 transporter deficient mutants, we conclude that nanosilica-induced peptide vesicles represent a new compartment of di- and tripeptide trapping which disrupts hydrolysis of nutrient peptides and metabolism.

Extended MARTINI Water Model for Heat Transfer Studies

Subjects: subject: Computational Physics (physics.comp-ph)

description: The computationally efficient classical MARTINI model is extended to simulate heat transfer simulations of water. The current MARTINI model, variations of it and other coarse grain water models focus on reproducing the thermodynamic properties below room temperature, hence making them unsuitable for studying high temperature simulations especially evaporation at 100 °C. In this work, the MARTINI model is reparametrized using a combination of Genetic Algorithm, Artificial Neural Network and Nelder-Mead optimization technique to match the phase equilibrium properties of water. The reparametrized model (MARTINI-E) accurately reproduces density, enthalpy of vaporization and surface tension at 100°C and outperforms other leading coarse grain water models. The model is also validated using the energy conservation and enthalpy change due to latent heat in a lamellar system. This new water model can be used for simulating phase change phenomena, thin film evaporation and other energy transport mechanisms accurately.

Ils indiquent que les spécimens «ont été tirés au hâvre Dorey » (= Manokwari) (Nouvelle-Guinée) et que la dissection montrait qu’il s’agissait d’un mâle et d’une femelle. La description des deux spécimens représentés planche 1 est très détaillée.Les auteurs ne signalent pas la présence d’une tache rouge sur leur ventre, et effectivement il n’y en a pas.D’après Collar & Rowley 1997, elle est d’importance très variable.

description: Excerpt from the report Summary: A new method of food distribution has developed with the advent of home freezers. This method entails selling bulk quantities of frozen food directly to consumers, often on a financed basis, and is known as freezer provisioning. Freezer provisioning began in the mid-1940's and has grown considerably since then. The locker and freezer provisioning industry is probably the most important group of businesses supplying bulk quantities of frozen food to home freezer owners. In a study made by Farmer Cooperative Service, a total of 2,546 locker and food provisioning establishments which comprised about one-fourth of the industry received questionnaires. They were selected because of their merchandising operations. The study put emphasis on determining factors influencing the success of their business activities.

description: We study the resonance behaviour of the forbidden 600 and 222 x-ray Bragg peaks in Ge using LDA band structure methods. These Bragg peaks remain forbidden in the resonant dipole scattering approximation even taking into account the non local nature of the band states. However they become allowed at resonance if the eigenstates of the unoccupied conduction band involve a hybridization of p like and d like atomic states. We show that the energy dependence of the resonant behaviour, including the phase of the scattering, is a direct measure of this p-d hybridization.and obtain quantitative agreement with experiment. A simple physical picture involving a product of dipole and quadrupolar transition matrix elements explains this behaviour and shows that it should be generally true for cases where the resonating atom is not at an inversion center. This has strong implications for the description of the resonance behavior of x-ray scattering in materials where the resonant atom is not at an inversion center such as V2O3 and in ferro and antiferro electric and piezo electric materials in general.

description: We study the problem of a magnetic polaron in an antiferromagnetic semiconductor (ferron). We obtain an analytical solution for the distortion produced in the magnetic structure of the d-spins due to the presence of a charge carrier bound to an impurity. The region in which the charge carrier is trapped is of the order of the lattice constant (small ferron) but the distortion of the magnetic structure extends over much larger distance. It is shown that the presence of this distortion makes the ferron more stable, and introduces a new length scale in the problem.

description: We introduce a fast Fourier spectral method for the multi-species Boltzmann collision operator. The method retains the riveting properties of the single-species fast spectral method (Gamba et al. SIAM J. Sci. Comput., 39 pp. B658--B674 2017) including: (a) spectral accuracy, (b) reduced computational complexity compared to direct spectral method, (c) reduced memory requirement in the precomputation, and (d) applicability to general collision kernels. The fast collision algorithm is then coupled with discontinuous Galerkin discretization in the physical space (Jaiswal et al. J. Comp. Phys., 378 pp. 178--208 2019) to result in a highly accurate deterministic method (DGFS) for the full Boltzmann equation of gas mixtures. A series of numerical tests is performed to illustrate the efficiency and accuracy of the proposed method. Various benchmarks highlighting different collision kernels, different mass ratios, momentum transfer, heat transfer, and in particular the diffusive transport have been studied. The results are directly compared with the direct simulation Monte Carlo (DSMC) method.

description: A two-lane extension of a recently proposed cellular automaton model for traffic flow is discussed. The analysis focuses on the reproduction of the lane usage inversion and the density dependence of the number of lane changes. It is shown that the single-lane dynamics can be extended to the two-lane case without changing the basic properties of the model which are known to be in good agreement with empirical single-vehicle data. Therefore it is possible to reproduce various empirically observed two-lane phenomena, like the synchronization of the lanes, without fine-tuning of the model parameters.

description: We study single hole motion in LaMnO$_3$ using the classical approximation for JT lattice distortions, a modified Lang-Firsov approximation for dynamical breathing-mode phonons, and the self-consistent Born approximation (verified by exact diagonalization) for hole-orbital-excitation scattering. We show that in the realistic parameter space for LaMnO$_3$, quantum effects of electron-phonon interaction are small. The quasiparticle bandwidth $W \simeq 2.2J$ in the purely orbital t-J model. It is strikingly broadened to be of order $t$ by strong static Jahn-Teller lattice distortions even when the polaronic band narrowing is taken into account.

Electrorotation of a pair of spherical particles

description: We present a theoretical study of electrorotation (ER) of two spherical particles under the action of a rotating electric field. When the two particles approach and finally touch, the mutual polarization interaction between the particles leads to a change in the dipole moment of the individual particle and hence the ER spectrum, as compared to that of the well-separated particles. The mutual polarization effects are captured by the method of multiple images. From the theoretical analysis, we find that the mutual polarization effects can change the characteristic frequency at which the maximum angular velocity of electrorotation occurs. The numerical results can be understood in the spectral representation theory.

description: We describe a paradigm for measuring a single electron spin in a solid. This is a fundamental problem in condensed matter physics. The technique can be used to read a spin qubit relatively non-invasively in either a spintronic quantum gate or a spintronic quantum memory. The spin reader can be self assembled by simple electrochemical techniques and can be integrated with a quantum gate.

Thermodynamics and steady state of quantum motors and pumps far from equilibrium

description: In this article, we briefly review dynamical and thermodynamical aspects of different forms of quantum motors and quantum pumps. We then extend previous results to provide new theoretical tools for a systematic study of those phenomena at far-from-equilibrium conditions. We mainly focus on two key topics: (1) The steady-state regime of quantum motors and pumps, paying particular attention to the role of higher-order terms in the nonadiabatic expansion of the current-induced forces. (2) The thermodynamical properties of such systems, emphasizing systematic ways of studying the relationship between different energy fluxes (charge and heat currents, and mechanical power) passing through the system when beyond-first-order expansions are required. We derive a general order-by-order scheme based on energy conservation to rationalize how every order of the expansion of one form of energy flux is connected with the others. We use this approach to give a physical interpretation of the leading terms of the expansion. Finally, we illustrate the above-discussed topics in a double quantum dot within the Coulomb-blockade regime and capacitively coupled to a mechanical rotor. We find many exciting features of this system for arbitrary nonequilibrium conditions: A definite parity of the expansion coefficients with respect to the voltage or temperature biases; negative friction coefficients; and the fact that, under fixed parameters, the device can exhibit multiple steady states where it may operate as a quantum motor or as a quantum pump depending on the initial conditions.

REMARQUES
 Ce taxon a tout d’abord été représenté par Hombron & Jacquinot (1846: pl. 26, fig. 1) sous le nom français de Cacatoës de Ducorps. Par la suite ces spécimens ont été décrits avec précision par Pucheran en 1853 qui leur a donné le nom latin de Cacatua ducorpsii. Cependant dès 1850 Bonaparte (1850b: 138) avait fait paraître quelques lignes à leur sujet. On y lit: «Plyctolophus DuCrops [sic], Hombron et Jac. figuré dans le Voyage au pôle sud, ayant petite huppe blanche ». L’erreur sur le nom ainsi que l’indigence de la description ont motivé une requête auprès de la Commission internationale de nomenclature zoologique (Eisenmann & Forshaw 1974), requête qui s’est soldée par la suppression de l’épithète spécifique DuCrops Bonaparte, 1850 et son remplacement par celle de ducorpsii Pucheran in Jacquinot & Pucheran, 1853 (ICZN 1981).

description: Der vorliegende Artikel setzt sich kritisch mit der von Victor Turner und John Sallnow geforderten kategorischen Unterscheidung von lokalen und regionalen Ritualen und insbesondere von Pilgerfahrt und Patronatsfesten auseinander. Er stützt sich auf ethnographische und ethnohistorische Daten aus dem Departement Cuzco/Peru und analysiert mit der Pilgerfahrt zum Qoyllur Rit’i und der Fronleichnamsfeier in Cuzco-Stadt zwei der wichtigsten religiösen Feiern der Region, auf welche sich auch Sallnow bezog. Gegenüber letzterem wird jedoch gezeigt, dass beide Veranstaltungen unmittelbar ineinander übergehen, ähnlicher Motivation entspringen, sich zahlreiche Teilnehmer und Symbole teilen. Damit wird deutlich, dass lokale und regionale Formen des Kultes nicht klar voneinander getrennt werden können.

Learning to Calibrate Straight Lines for Fisheye Image Rectification

description: This paper presents a new deep-learning based method to simultaneously calibrate the intrinsic parameters of fisheye lens and rectify the distorted images. Assuming that the distorted lines generated by fisheye projection should be straight after rectification, we propose a novel deep neural network to impose explicit geometry constraints onto processes of the fisheye lens calibration and the distorted image rectification. In addition, considering the nonlinearity of distortion distribution in fisheye images, the proposed network fully exploits multi-scale perception to equalize the rectification effects on the whole image. To train and evaluate the proposed model, we also create a new largescale dataset labeled with corresponding distortion parameters and well-annotated distorted lines. Compared with the state-of-the-art methods, our model achieves the best published rectification quality and the most accurate estimation of distortion parameters on a large set of synthetic and real fisheye images.

description: We present a detailed analysis of single-vehicle data which sheds some light on the microscopic interaction of the vehicles. Besides the analysis of free flow and synchronized traffic the data sets especially provide information about wide jams which persist for a long time. The data have been collected at a location far away from ramps and in the absence of speed limits which allows a comparison with idealized traffic simulations. We also resolve some open questions concerning the time-headway distribution.
