description: We formulate entropic Leggett-Garg inequalities, which place constraints on the statistical outcomes of temporal correlations of observables. The information theoretic inequalities are satisfied if macrorealism holds. We show that the quantum statistics underlying correlations between time-separated spin component of a quantum rotor mimics that of spin correlations in two spatially separated spin-$s$ particles sharing a state of zero total spin. This brings forth the violation of the entropic Leggett-Garg inequality by a rotating quantum spin-$s$ system in similar manner as does the entropic Bell inequality (Phys. Rev. Lett. 61, 662 (1988)) by a pair of spin-$s$ particles forming a composite spin singlet state.

description: We present analytical formulas for the calculation of the two-center two-electron integrals in the basis of Slater geminals and products of Slater orbitals. Our derivation starts with establishing a inhomogeneous fourth-order ordinary differential equation that is obeyed by the master integral, the simplest integral with inverse powers of all interparticle distances. To solve this equation it was necessary to introduce a new family of special functions which are defined through their series expansions around regular singular points of the differential equation. To increase the power of the interparticle distances under the sign of the integral we developed a family of open-ended recursion relations. A handful of special cases of the integrals is also analysed with some remarks on simplifications that occur. Additionally, we present some numerical examples of the master integral that validate the usefulness and correctness of the key equations derived in this paper. In particular, we compare our results with the calculations based on the series expansion of the exp(-γr12) term in the master integral.

description: Distinguishing quark-initiated jets from gluon-initiated jets has the potential to significantly improve the reach of many beyond-the-standard model searches at the Large Hadron Collider and to provide additional tests of QCD. To explore whether quark and gluon jets could possibly be distinguished on an event-by-event basis, we perform a comprehensive simulation-based study. We explore a variety of motivated and unmotivated variables with a semi-automated multivariate approach. General conclusions are that at 50% quark jet acceptance efficiency, around 80%-90% of gluon jets can be rejected. Some benefit is gained by combining variables. Different event generators are compared, as are the effects of using only charged tracks to avoid pileup. Additional information, including interactive distributions of most variables and their cut efficiencies, can be at http://jets.physics.harvard.edu/qvg.

description: Dieser Beitrag thematisiert die historische Entwicklung des Instituts der Duldungsvollmacht ab dem Ende des 19. Jahrhunderts. Die durch den wachsenden Handel zunehmend auftretende Problematik der Vollmacht durch Duldung wird – insbesondere im Hinblick auf deren dogmatische Begründung – bereits seit dieser Zeit kontrovers diskutiert. Aufgezeigt wird ein Wandel von der stillschweigenden Bevollmächtigung hin zur Rechtsscheinvollmacht und damit von einer Fiktions- zu einer Zurechnungslösung. Erörtert wird außerdem, weswegen die Entscheidung zugunsten der Rechtsscheinvollmacht zur Zeit der nationalsozialistischen Diktatur – entgegen mancher Stimmen in der Literatur – durchaus in die nationalsozialistische Ideologie passt.

description: The rise of the total, elastic and inelastic hadronic cross sections at high energies is investigated by means of an analytical parametrization, with the exponent of the leading logarithm contribution as a free fit parameter. Using derivative dispersion relations with one subtraction, two different fits to proton-proton and antiproton-proton total cross section and rho parameter data are developed, reproducing well the experimental information in the energy region 5 GeV - 7 TeV. The parametrization for the total cross sections is then extended to fit the elastic (integrated) cross section data in the same energy region, with satisfactory results. From these empirical results we extract the energy dependence of several physical quantities: inelastic cross section, ratios elastic/total, inelastic/total cross sections, ratio total-cross-section/elastic-slope, elastic slope and optical point. All data, fitted and predicted, are quite well described. We find a statistically consistent solution indicating: (1) an increase of the hadronic cross sections with the energy faster than the log-squared bound by Froissart and Martin; (2) asymptotic limits 1/3 and 2/3 for the ratios elastic/total and inelastic/total cross sections, respectively, a result in agreement with unitarity. These indications corroborate recent theoretical arguments by Ya. I. Azimov on the rise of the total cross section.

description: Report Summary: Eleven kinds of fresh fruits were irradiated to determine possible extension of the market life. Irradiation of strawberries and two varieties of fig extended the market life by several days through reduction of decay, without apparent impairment of fruit quality. Brown rot, but not Rhizopus rot, of peaches and nectarines was controlled; the peaches softened during irradiation and subsequently developed more red color but less flavor than the controls. Radiation inhibited blue coloring of plums and increased softening of the fruits. Low doses inhibited ripening of pears by several days, but the resultant ripening was abnormal. Decay of grapes was controlled less effectively by radiation than by the customary sulfur dioxide fumigation. Radiation increased rind pitting of oranges without reducing decay during semicommercial tests. Irradiated apples were softer, more shriveled, and had less flavor than the controls following storage for 3 to 6 months. Avocados and olives were severely discolored both internally and externally by radiation. Individual varieties of peaches and figs responded quite differently to radiation. Water on the surface of peaches during irradiation caused spotting of the skin. The stage of development of fungal infections determined the effectiveness of radiation as a decay-control agent for oranges. Fruit maturity within the limits of these experiments did not affect the responses to radiation

description: We consider the electronic structure of a slightly twisted graphene bilayer and show the coexistence of van Hove singularities (VHSs) and superlattice Dirac points in a continuum approximation. The graphene-on-graphene moiré pattern gives rise to a periodic electronic potential, which leads to the emergence of the superlattice Dirac points due to the chiral nature of the charge carriers. Owning to the distinguishing real and reciprocal structures, the sublattice exchange even and odd structures of the twisted graphene bilayer (the two types of commensurate structures) result in two different structures of the superlattice Dirac points. We further calculate the effect of a strain on the low-energy electronic structure of the twisted graphene bilayer and demonstrate that the strain affects the position of the VHSs dramatically.

description: This chapter is aimed at critically exploring some key issues around data that concern us not only individually, but also, at the collective level. How we analyse and interact with data, how data is shaping our society, which are the legal frameworks around uses of data and how we can challenge the uses that are given to our data are explored. In the first unit, the basics of data ethics are probed. In the second one, the fundamental principles that govern what is right and what is wrong in the data cycle, from collection and production to their use are considered. The concepts of data privacy pertaining to the regulations and laws about data opening, publishing, collection, storage and management are examined. In the third unit, critical approaches to AI and algorithms are reviewed. Issues, such as opacity and bias in algorithms, as well as regulations for automated decision and predictive analytics that are underpinned by and lead to power imbalances, thus constraining opportunities for participation, are discussed. Finally, the fourth unit is focused on personal agency, where the aim is to enable citizens to contest the uses of their data with the wherewithal to challenge the advancement of data power.

To facilitate easy integration of the fast Single Instruction Multiple Data (SIMD) SW algorithm into third party software, we wrote a C/C++ library, which extends Farrars Striped SW (SSW) to return alignment information in addition to the optimal SW score. Availability: SSW is available both as a C/C++ software library, as well as a stand alone alignment tool wrapping the librarys functionality at https://github.com/mengyao/Complete- Striped-Smith-Waterman-Library Contact: marth@bc.edu

description: Magnetic skyrmions are quasiparticles with nontrivial topology, envisioned to play a key role in next-generation data technology while simultaneously attracting fundamental research interest due to their emerging topological charge. In chiral magnetic multilayers, current-generated spin–orbit torques or ultrafast laser excitation can be used to nucleate isolated skyrmions on a picosecond time scale. Both methods, however, produce randomly arranged skyrmions, which inherently limits the precision on the location at which the skyrmions are nucleated. Here, we show that nanopatterning of the anisotropy landscape with a He+-ion beam creates well-defined skyrmion nucleation sites, thereby transforming the skyrmion localization into a deterministic process. This approach allows control of individual skyrmion nucleation as well as guided skyrmion motion with nanometer-scale precision, which is pivotal for both future fundamental studies of skyrmion dynamics and applications.

description: The cross-over region of the quark-gluon plasma (QGP) created in heavy ion collisions is influenced by the nearby deconfinement, chiral and baryon condensation phase transitions. A characteristic signature of the deconfinement transition in this region can be infered using the flux tube model, which is dual to the Polyakov loop description and which offers a visual picture of what happens during the transition. The three-point (anti)vertices of a flux tube network lead to formation of (anti)baryons upon hadronisation. Since there is no fundamental interaction associated with the baryon number, correlations in the baryon number distribution at the last scattering surface directly reflect the preceding pattern of the flux tube vertices in the QGP. An alternating pattern of vertices and antivertices would lead to an oscillatory signal in the two-point baryon number correlations, under the experimental conditions prevalent in heavy ion collisions at RHIC and LHC. The strength of the oscillations is a measure of the flexibility of the QGP.

description: The ground state band was recently observed in the superheavy nucleus 256Rf. We study the rotational properties of 256Rf and its neighboring even-even nuclei by using a cranked shell model (CSM) with the pairing correlations treated by a particle-number conserving (PNC) method in which the blocking effects are taken into account exactly. The kinematic and dynamic moments of inertia of the ground state bands in these nuclei are well reproduced by the theory. The spin of the lowest observed state in 256Rf is determined by comparing the experimental kinematic moments of inertia with the PNC-CSM calculations and agrees with previous spin assignment. The effects of the high order deformation varepsilon6 on the angular momentum alignments and dynamic moments of inertia in these nuclei are discussed.

description: In this work we consider various correlators with Schur polynomials in ABJ(M) models that on the dual gravity side should correspond to processes involving giant gravitons. Our analysis imposes several constraints on the physics of the probe branes on AdS4xCP3 as well as sheds more light on giant graviton solutions in this background with additional NS B-field. Our main tool is a formula that we derive for extremal n-point functions of the single trace chiral primary operators in the free field theory limit. The formula expresses the correlators in terms of the two-point function of Schur polynomials labeled by hook diagrams and is valid for a large class of gauge theories. In particular, in N = 4 SYM, it proves the conjecture of Beisert et al.

description: Excerpts from the report: Each year a part of the tomato crop shipped for fresh use is harvested in the "pink" stage after some yellow or red has developed. Ripening does not progress uniformly in tomatoes on the vines, and fruits of various stages of ripeness are obtained even when the fruits are harvested frequently. Fruits of different stages of ripeness are sorted and packed in similar ranges. They may be shipped separately or all may be included in the same load. Pink tomatoes are at times also shipped in loads of mixed produce. Since these pink, or so-called vine-ripened, tomatoes are more perishable than those harvested mature green, one of the critical problems is to control ripening during transit. The purpose of this study was to determine (1) the effect of simulated transit temperatures on the rate of color change and final ripening and (2) whether short periods at relatively low temperatures, such as during transit in mixed loads of vegetables, would cause chilling injury.

The most important problem is selection of proper temperatures for the 2- to 4-week export transit period for fruit shipped at various maturities from early fall to late spring. This report summarizes the results of simulated export studies conducted at the U.S. Department of Agriculture Horticultural Field Station, Orlando, Fla., and test shipments of Florida grapefruit to West Germany in 1961-62, 1962-63, and 1963-64 seasons. An observer accompanied the test shipments. The objective was to determine optimum environments for reduction of spoilage and maintenance of quality of fruit exported for the European market

description: The monopole mass is revealed to be considerably modified in the thick braneworld paradigm, and depends on the position of the monopole in the brane as well. Accordingly, the monopole radius continuously increases, leading to an unacceptable setting that can be circumvented when the brane thickness has an upper limit. Despite such peculiar behavior, the quantum corrections accrued -- involving the classical monopole solution -- are shown to be still under control. We analyze the monopole's peculiarities also taking into account the localization of the gauge fields. Furthermore, some additional analysis in the thick braneworld context and the similar behavior evinced by the topological string are investigated.

In this paper we quantify the ability of a future measurement of the Sandage-Loeb signal by a CODEX-like spectrograph to constrain a phenomenological parametrization of dynamical dark energy, specifically by obtaining constraints on $w_0$ and $w_a$. We also demonstrate that if used alongside CMB data, the Sandage-Loeb measurements will be able to break degeneracies between expansion parameters, thus greatly improving cosmological constraints.

description: We investigate the two-body properties of a spin-1/2 Fermi gas subject to a spin-orbit coupling induced by laser fields. When an attractive s-wave interaction between unlike spins is present, the system may form a dimer bound state. Surprisingly, in the presence of a Zeeman field along the direction of the spin-orbit coupling, the bound state obtains finite center-of-mass mechanical momentum, whereas under the same condition but in the absence of the two-body interaction, the system has zero total momentum. This unusual result can be regarded as a consequence of the broken Galilean invariance by the spin-orbit coupling. Such a finite-momentum bound state will have profound effects on the many-body properties of the system.

description: Excerpts from the report: Air shipments of strawberries from California to eastern and midwestern markets have almost doubled in volume during each of the past 3 years. Handling practices for strawberries shipped by air have varied greatly, and little research has been conducted to determine how these practices affect fruit quality. The objectives of this test were to relate spoilage and market quality to each of the following factors: 1. Time, temperature, and handling procedures in each portion of the transit period; 2. Precooling the fruit before shipment; 3. Use of dry ice to modify the atmosphere in transit; and 4. Use of various types of pallet covers to retain the modified atmosphere produced by the dry ice and also to provide physical protection for the berries.

The ITN CyclonHit and the MSCA-IF Polar Star projects aretwo examples of EC commitment and focus on cyclodextrin (CD)-based nanocarriers toencapsulate, protect and potentiate known drugs to fight resistant bacteria and prostate cancer,respectively.In the frame of CyclonHit project, we developed biocompatible and biodegradablepolymeric CD nanoparticles (pCD NPs) able to coencapsulate by a “green” method two potentanti-tuberculosis molecules which are insoluble in biologically-compatible solvents. Theformulation process was complicated by the completely different physico-chemical properties ofthe two active agents and by the strong tendency to crystallize of one of them. The developedcarriers were spectroscopically characterized proving that the drugs were encapsulated at amolecular level not only in the CD cavities but also in the intermingled polymeric chains. Theefficacy of the developed NPs was demonstrated in vitro and in vivo. In particular, theaerosolized NPs suspension led to a 3-log decrease of the pulmonary bacterial load of infectedanimals after only 6 administrations. Interestingly, the unloaded pCD NPs exhibited themselvesa good antibacterial effect contributing to the action of the two active molecules.In the frame ofPolar Star, CD-based NPs are tailored to increase the effectiveness and the specificity ofknown drugs against castrate-resistant prostate cancer. The NPs are composed of innovativemixed polymers combining α, β and γ-CD in single polymers to improve loading capacity fordifferent therapeutic agents. The final goal is to exploit multicargo NPs able to act acrossmultiple oncogenic pathways.

description: We systematically develop Weyl-Titchmarsh theory for singular differential operators on arbitrary intervals $(a,b) \subseteq \mathbb{R}$ associated with rather general differential expressions of the type \[ τf = \frac{1}{r} (- \big(p[f' + s f]\big)' + s p[f' + s f] + qf),] where the coefficients $p$, $q$, $r$, $s$ are real-valued and Lebesgue measurable on $(a,b)$, with $p\neq 0$, $r>0$ a.e.\ on $(a,b)$, and $p^{-1}$, $q$, $r$, $s \in L^1_{\text{loc}}((a,b); dx)$, and $f$ is supposed to satisfy [f \in AC_{\text{loc}}((a,b)), \; p[f' + s f] \in AC_{\text{loc}}((a,b)).] In particular, this setup implies that $τ$ permits a distributional potential coefficient, including potentials in $H^{-1}_{\text{loc}}((a,b))$. We study maximal and minimal Sturm-Liouville operators, all self-adjoint restrictions of the maximal operator $T_{\text{max}}$, or equivalently, all self-adjoint extensions of the minimal operator $T_{\text{min}}$, all self-adjoint boundary conditions (separated and coupled ones), and describe the resolvent of any self-adjoint extension of $T_{\text{min}}$. In addition, we characterize the principal object of this paper, the singular Weyl-Titchmarsh-Kodaira $m$-function corresponding to any self-adjoint extension with separated boundary conditions and derive the corresponding spectral transformation, including a characterization of spectral multiplicities and minimal supports of standard subsets of the spectrum. We also deal with principal solutions and characterize the Friedrichs extension of $T_{\text{min}}$. Finally, in the special case where $τ$ is regular, we characterize the Krein-von Neumann extension of $T_{\text{min}}$ and also characterize all boundary conditions that lead to positivity preserving, equivalently, improving, resolvents (and hence semigroups).

description: A noncooperative game theoretical approach for analysing opportunistic spectrum access (OSA) in cognitive radio (CR) environments is proposed. New concepts from game theory are applied to spectrum access analysis in order to extract rules of behaviour for an emerging environment. In order to assess OSA scenarios of CRs, two oligopoly game models are reformulated in terms of resource access: Cournot and Stackelberg games. Five CR scenes are analysed: simultaneous access of unlicensed users (commons regime) with symmetric and asymmetric costs, with and without bandwidth constraints and sequential access (licensed against unlicensed). Several equilibrium concepts are studied as game solutions: Nash, Pareto and the joint NashPareto equilibrium. The latter captures a game situation where players are non-homogeneous users, exhibiting different types of rationality, Nash and Pareto. This enables a more realistic modelling of interactions on a CR scene. An evolutionary game equilibrium detection method is used. The Nash equilibrium indicates the maximum number of channels a CR may access without decreasing its payoff. The Pareto equilibrium describes a larger range of payoffs, capturing unbalanced as well as equitable solutions. The analysis of the Stackelberg modelling shows that payoffs are maximised for all users if the incumbents are Nash oriented and the new entrants are Pareto driven.

description: Ticks, notorious blood-feeders and disease-vectors, have lost a part of their genetic complement encoding haem biosynthetic enzymes and are, therefore, dependent on the acquisition and distribution of host haem. Solute carrier protein SLC48A1, aka haem-responsive gene 1 protein (HRG1), has been implicated in haem transport, regulating the availability of intracellular haem. HRG1 transporter has been identified in both free-living and parasitic organisms ranging from unicellular kinetoplastids, nematodes, up to vertebrates. However, an HRG1 homologue in the Arthropod lineage has not yet been identified. We have identified a single HRG1 homologue in the midgut transcriptome of the tick Ixodes ricinus, denoted as IrHRG, and have elucidated its role as a haem transporter. Data from haem biosynthesis-deficient yeast growth assays, systemic RNA interference and the evaluation of Gallium protoporphyrin IX-mediated toxicity through tick membrane feeding clearly show that IrHRG is the bona fide tetrapyrrole transporter. We argue that during evolution, ticks profited from retaining a functional hrg1 gene in the genome because its protein product facilitates host haem escort from intracellularly digested haemoglobin, rendering haem bioavailable for a haem-dependent network of enzymes.

description: Multiplicative white-noise stochastic processes continuously attract the attention of a wide area of scientific research. The variety of prescriptions available to define it difficults the development of general tools for its characterization. In this work, we study equilibrium properties of Markovian multiplicative white-noise processes. For this, we define the time reversal transformation for this kind of processes, taking into account that the asymptotic stationary probability distribution depends on the prescription. Representing the stochastic process in a functional Grassman formalism, we avoid the necessity of fixing a particular prescription. In this framework, we analyze equilibrium properties and study hidden symmetries of the process. We show that, using a careful definition of equilibrium distribution and taken into account the appropriate time reversal transformation, usual equilibrium properties are satisfied for any prescription. Finally, we present a detailed deduction of a covariant supersymmetric formulation of a multiplicative Markovian white-noise process and study some of the constraints it imposes on correlation functions using Ward-Takahashi identities.

description: In a recent work, Bodineau and Derrida analyzed the phase fluctuations in the ABC model. In particular, they computed the asymptotic variance and, on the basis of numerical simulations, they conjectured the presence of a drift, which they guessed to be an antisymmetric function of the three densities. By assuming the validity of the fluctuating hydrodynamic approximation, we prove the presence of such a drift, providing an analytical expression for it. This expression is then shown to be an antisymmetric function of the three densities. The antisymmetry of the drift can also be inferred from a symmetry property of the underlying microscopic dynamics.

description: We propose a model of Sinai billiards with moving scatterers, in which the locations and shapes of the scatterers may change by small amounts between collisions. Our main result is the exponential loss of memory of initial data at uniform rates, and our proof consists of a coupling argument for non-stationary compositions of maps similar to classical billiard maps. This can be seen as a prototypical result on the statistical properties of time-dependent dynamical systems.
