description: Piezotronics is an emerging field, which exploits strain to control the transport properties in condensed matters. At present, piezotronics research majorly focuses on insulators with tunable electric dipole by strain. Metals are excluded in this type of applications due to the absence of electric dipole. The recently discovered Berry curvature dipole can exist in metals, thus introduces the possibility of the piezotronics phenomena in them. In this paper, we predict that strain can switch the Berry curvature dipole, and lead the nonlinear Hall effect in the two-dimensional (2D) 1$H$-MX$_2$ (M=Nb, Ta; X=S, Se). Based on symmetry analysis and first-principles calculations, we show these 2D monolayer metals have the desired piezotronics property: without strain the Berry curvature dipole is eliminated by symmetry, prohibiting the nonlinear Hall effect; while uniaxial strain can effectively reduce the symmetry to introduce sizable Berry curvature dipole, and it can generate observable Hall voltage in a reasonable experimental condition. Therefore, our work manifests that the 2D metallic 1$H$-MX$_2$ (M=Nb, Ta; X=S, Se) are the ideal platform for piezotronics.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

description: In recent years, U.S. public policymakers have attempted to redirect the grain exporting network from a quasi market-oriented system toward a more market-managed system (Weaver Bill, 96th Congress, H.R. 4237; Roth-Stevenson Bill, 96th Congress, S. 2773). The economic implications of these proposed actions are unclear. Several studies have commenced examination of this very complex issue (Peltier and Anderson, McCalla and Schmitz, Martin, Thompson and Dahl). The purpose of this paper is to improve our understanding of the subject by describing another major grain export marketing system and to investigate a number of methodological issues with respect to measuring the performance of the Australian export marketing system. This paper is the framework for a proposed study to be completed at Texas A&M University; therefore, it does not present research results or policy conclusions. A brief description of the wheat marketing system is followed by an outline for examining Australian grain export marketing performance.
A quantum-corrected approach to black hole radiation via a tunneling process

description: In the language of black hole physics, Hawking radiation is one of the most controversial subjects about which there exist lots of puzzles, including the information loss problem and the question of whether this radiation is thermal or not. In this situation, a possible way to face these problems is to bring quantum effects into play, also taking into account self-gravitational effects in the scenario. We consider a quantum-corrected form of the Schwarzschild black hole inspired by the pioneering work of Kazakov and Solodukhin to modify the famous Parikh-Wilczek tunneling process for Hawking radiation. We prove that in this framework the radiation is not thermal, with a correlation function more effective than the Parikh-Wilczek result, and the information loss problem can be addressed more successfully. Also, we realize that quantum correction affects things in the same way as an electric charge. So, it seems that quantum correction in this framework has something to do with the electric charge.

Figs. 3, 49, 57, 70
 Type Material. Holotype (male): “ BRAZIL: Rondonia, Machadinho d’Oeste, Balneário São José (-9.44573 - 61.98332), 103 m.; 9.vii.2018, leg. Short, margins of various places on river, BR18-0709-01A” (INPA). Paratype: Same data as holotype (1 SEMC).
 Differential Diagnosis. Among Brazilian species, recognized by the combination of small size (ca. 2.28 mm), black color, the sculptured dorsum, with deep foveae, raised elytral intervals, small callus of 5 th elytral interstria, and the male genitalia (Fig. 49; described below). Reliable differentiation from other similarly small sized black species with raised or costate elytra should include dissection of males.
 Description. Size: holotype (length/width, mm): body (length to elytral apices) 2.28/0.91; head width 0.59; pronotum l/w 0.54/0.58; PA 0.58; PB 0.46; elytra 1.45/0.91. Habitus as illustrated (Fig. 49). Dorsum black. Legs brown, lateral margin of tibiae with row of spines. Head with frons medially slightly tumid, with longitudinal punctate groove on each side of tumidity. Punctation on elytra ca. 3–5x that of pronotum. 5 th interstria raised, with usual callus, very small, low.
Pronotum slightly wider than long (ratio ca. 16/15), widest at anterior margin, strongly narrowed at base, sides weakly sinuate, non-denticulate; anterior margin bisinuate; lateral and anterior margins with row of moderately long setae; depressions large, deep, much more densely punctate than almost impunctate reliefs.
Elytra with intervals 3, 5, 7, and 9 very slightly raised, not costate; punctures large, spaces between strial punctures narrow walls to 1xpd, many punctures in off-set zig-zag pattern; apices acuminate, truncate apically in dorsal view, in lateral view outer margin without angulation.
Ventral characters: Mentum moderately coarsely and moderately densely punctate, with shallow median fovea. Submentum narrow, without foveae.
Male genitalia (Fig. 49) general characters: genitalia without parameres, basal piece elongate, trisinuate in lateral view, in dorsal/ventral views straight, slightly widened at ca. midlength and distal 3/4; distal end produced in microreticulate lobe on dorsal surface, ventral apex produced in short beak-like shape.
 Etymology. Named in reference to the width of the elytra at the humeral angles.
 Remarks. The holotype has dorsal encrustations, which defied removal. This adversely affected the habitus images.

description: Natural antiparasitic agents are used as a strategy for advances in the treatment of neglected tropical diseases (NTDs), such as giardiasis. The present paper identified the compounds produced by Ganoderma lipsiense mycelium grown in submerged fermentation and investigated the antigiardial activity potential of extracts in vitro. G. lipsiense mycelium crude extract (CE) was obtained by the maceration process and after purification in column, thirty compounds were identified by gas chromatography - mass spectrometry (GC-MS) in hexane sub-fraction (HSF). To determine the antigiardial potential, different parts of the purified CE have been evaluated, where hexane (HEXf) and dichloromethane (DCMf) fractions showed in vitro reduction levels higher than 90% of the Giardia duodenalis trophozoites at 100 μg mL−1. This antigiardial activity was investigated aiming to explore the possibility of G. lipsiense mycelium extract as a novel antigiardial compound to the treatment of human giardiasis.

description: The physical properties of ultrathin NaCl overlayers on the stepped Cu(311) surface have been characterized using scanning tunneling microscopy (STM) and spectroscopy, and density functional calculations. Simulations of STM images and differential conductance spectrum were based on the Tersoff-Hamann approximation for tunneling with corrections for the modified tunneling barrier at larger voltages and calculated Kohn-Sham states. Characteristic features observed in the STM images can be directly related to calculated electronic and geometric properties of the overlayers. The measured apparent barrier heights for the mono-, bi-, and trilayers of NaCl and the corresponding adsorption-induced changes in the work function, as obtained from the distance dependence of the tunneling current, are well reproduced by and understood from the calculated results. The measurements revealed a large reduction of the tunneling conductance in a wide voltage region, resembling a band gap. However, the simulated spectrum showed that only the onset at positive sample voltages may be viewed as a valence band edge, whereas the onset at negative voltages is caused by the drastic effect of the electric field from the tip on the tunneling barrier.
Influence of branch points in the complex plane on the transmission through double quantum dots

description: We consider single-channel transmission through a double quantum dot system consisting of two single dots that are connected by a wire and coupled each to one lead. The system is described in the framework of the S-matrix theory by using the effective Hamiltonian of the open quantum system. It consists of the Hamiltonian of the closed system (without attached leads) and a term that accounts for the coupling of the states via the continuum of propagating modes in the leads. This model allows to study the physical meaning of branch points in the complex plane. They are points of coalesced eigenvalues and separate the two scenarios with avoided level crossings and without any crossings in the complex plane. They influence strongly the features of transmission through double quantum dots.

description: We report on experimental and theoretical demonstration of an optical comb spectrum based on a combination of cascaded stimulated Raman scattering and four-wave mixing mediated by Raman-induced nonresonant Kerr-type nonlinearity. This combination enabled to transform a conventional quasi-periodic Raman comb into a comb with a single and smaller frequency spacing. This new phenomenon is realized using a hollow-core photonic crystal fiber filled with 40 bars of deuterium, and pumped with a high-power picosecond laser. The resultant comb shows more than 100 spectral lines spanning over 220 THz from 800 nm to 1710 nm, with a total output power of 7.1 W. In contrast to a pure Raman comb, a 120 THz wide portion of the spectrum exhibits denser and equally-spaced spectral lines with a frequency spacing of around 1.75 THz, which is much smaller than the lowest frequency of the three excited deuterium Raman resonances. A numerical solution of the generalized nonlinear Schrödinger equation in the slowly varying envelope approximation provides very good agreement with the experimental data. The additional sidebands are explained by cascaded four-wave mixing between pre-existing spectral lines, mediated by the large Raman induced optical nonlinearity. The results open a new route to the generation of optical frequency combs that combine large bandwidth and high power controllable frequency spacing.

WZ Sge: HST Spectroscopy of the Cooling of the White Dwarf after the 2001 Outburst

description: Following an outburst in 2001 July, the UV flux of WZ Sge has declined slowly toward pre-outburst levels. Here, we describe new 1150-1710 Angstrom HST/STIS spectra of WZ Sge obtained between 2002 April and 2003 March to follow the decline. A combined analysis of these and spectra obtained in the fall of 2001 show that if log g=8.5, then the white dwarf temperature decreased from 23,400 K in 2001 October, shortly after the steady decline of the system began, to 15,900 K 17 months later. The UV flux in 2003 March was still 2.4 times higher than measured prior to the outburst and so the system was still recovering from the outburst. During this period, the shape of the spectrum and the flux from the system are consistent with a log g=8.5, 0.9 solar mass white dwarf at the astrometrically-determined distance to WZ Sge. Although the spectrum from 2001 September resembles that of a white dwarf with a temperature of 28,200 K, the implied radius is smaller than in the remainder of the observations. If the entire white dwarf was visible in 2001 September, then either a second component, such as the disk emission, was distorting the spectrum, or more likely, the temperature on the white dwarf photosphere was not uniform then. The metal lines in the spectra of WZ Sge have weakened with time. Model fits that allow for material along the line of sight to the white dwarf photosphere are substantial improvements over models which assume all the lines arise from the photosphere. This obviates the need to explain very unusual abundance ratios in the photosphere and complicates the determination of the rotation rate of the white dwarf.

description: During solar flares, magnetic energy can be converted into electromagnetic radiation from radio waves to $γ$ rays. Enhancements in the continuum at visible wavelengths give rise to white-light flares, as well as continuum enhancements in the FUV and NUV passbands. In addition, the strong energy release in these events can lead to the rearrangement of the magnetic field at the photospheric level, causing morphological changes in large and stable magnetic structures like sunspots. In this context, we describe observations acquired by satellite instruments (IRIS, SDO/HMI, Hinode/SOT) and ground-based telescopes (ROSA/DST) during two consecutive C7.0 and X1.6 flares occurred in active region NOAA 12205 on 2014 November 7. The flare was accompanied by an eruption. The results of the analysis show the presence of continuum enhancements during the evolution of the events, observed both in ROSA images and in \textit{IRIS} spectra. In the latter, a prominent blue-shifted component is observed at the onset of the eruption. We investigate the role played by the evolution of the $δ$ sunspots of the active region in the flare triggering, and finally we discuss the changes in the penumbrae surrounding these sunspots as a further consequence of these flares.

description: Natural products, especially plants, have been investigated as sources of new substances with antimicrobial properties. In this context, the Myrcia genus is extensively researched for presenting such activities. This work aims to evaluate the antifungal, antibacterial, and antioxidant properties of extracts and fractions of stems of Myrcia hatschbachii, also to characterize two phenolic compounds. The antibacterial and antifungal activities were assessed by using the broth microdilution method. The ethyl acetate fraction (FGA) inhibited the growth of Candida albicans at a Minimum Inhibitory Concentration (MIC) of 15.6 µg/mL, presented 40% of phenolic compounds in its composition, obtained the most significant results in antioxidant methods (DPPH, FRAP, ABTS), besides the identification of ellagic and 3-O-methyl ellagic acids by NMR. Considering the relevant antifungal activity revealed by the fraction, new studies can be carried out to encourage the continuous search for antifungal alternatives.

description: Discrete conjugate systems are quadrilateral nets with all planar faces. Discrete orthogonal systems are defined by the additional property of all faces being concircular. Their geometric properties allow one to consider them as proper discretization of conjugate, resp. orthogonal coordinate systems of classical differential geometry. We develop techniques that allow us to extend this known qualitative analogy to rigorous convergence results. In particular, we prove the $C^\infty$-convergence of discrete conjugate/orthogonal coordinate systems to smooth ones. We also show how to construct the approximating discrete nets. Coordinate systems and their transformations are treated on an equal footing, and the approximation results hold for transformations as well.

description: A composite supply response model is formulated that has extrapolative and rational components as well as a partial adjustment mechanism. The model is applied to the Florida Watermelon Market to investigate how producers are forming their expectation of watermelon prices at harvest time. The results show that a dynamic cobweb mechanism is a valid representation of the data and suggests that producers are not using all the relevant information in the market.

description: We present evidence for a simple linear relationship between the orbital period and super-orbital period in ultra-luminous X-ray (ULX) pulsars, akin to what is seen in the population of disc-fed neutron star super-giant X-ray binary and Be/X-ray binary systems. We argue that the most likely cause of this relationship is the modulation of precessing hot spots or density waves in an accretion or circumstellar disc by the binary motion of the system, implying a physical link between ULX pulsars and high-mass X-ray binary (HMXB) pulsars. This hypothesis is supported by recent studies of Galactic and Magellanic Cloud HMXBs accreting at super-Eddington rates, and the position of ULX pulsars on the spin period--orbital period diagram of HMXBs. An interesting secondary relationship discovered in this work is the apparent connection between disc-fed HMXBs, ULXs and a seemingly unrelated group of early-type binaries showing so-called "double-periodic" variability. We suggest that these systems are good candidates to be the direct progenitors of Be/X-ray binaries.

description: The methanolic extract of the waste seeds of Sesamum indicum L. (Pedaliaceae) was subjected to chromatographic fractionation; it led to the isolation of an alkyl benzene identified as 1,3-bis (pentadecyl)benzene (1) along with three known fatty acids: oleic acid (2), linoleic acid (3), and palmitic acid (4); one monosaturated cardanol, 3-pentadecylphenol (5) and two phytosteroids identified as sitostanol (6) and campestanol (7). The structures of these compounds were elucidated by chemical and spectroscopic analyses. Compounds 1, 5 and 6 were evaluated against protozoan parasites. Compound 1 moderately inhibited the promastigote form of Leishmania donovani LG13 with IC50 equal to 16.9 μM.

description: We renormalize a six dimensional cubic theory to four loops in the MSbar scheme where the scalar is in a bi-adjoint representation. The underlying model was originally derived in a problem relating to gravity being a double copy of Yang-Mills theory. As a field theory in its own right we find that it has a curious property in that while unexpectedly there is no one loop contribution to the $β$-function the two loop coefficient is negative. It therefore represents an example where asymptotic freedom is determined by the two loop term of the $β$-function. We also examine a multi-adjoint cubic theory in order to see whether this is a more universal property of these models.

description: Cr 2p core excited XAS and XMCD spectra of ferromagnetic Cr$_{1-δ}$Te with several concentrations of $δ$=0.11-0.33 and ferrimagnetic Cr$_{5}$S$_{6}$ have been measured. The observed XMCD lineshapes are found to very weakly depend on $δ$ for Cr$_{1-δ}$Te. The experimental results are analyzed by means of a configuration-interaction cluster model calculation with consideration of hybridization and electron correlation effects. The obtained values of the spin magnetic moment by the cluster model analyses are in agreement with the results of the band structure calculation.The calculated result shows that the doped holes created by the Cr deficiency exist mainly in the Te 5porbital of Cr$_{1-δ}$Te, whereas the holes are likely to be in Cr 3d state for Cr$_{5}$S$_{6}$.

description: Bi$_2$Se$_3$ nanoribbons, grown by catalyst-free Physical Vapour Deposition, have been used to fabricate high quality Josephson junctions with Al superconducting electrodes. The conductance spectra (dI/dV) of the junctions show clear dip-peak structures characteristic of multiple Andreev reflections. The temperature dependence of the dip-peak features reveals a highly transparent Al/Bi$_2$Se$_3$ topological insulator nanoribbon interface and Josephson junction barrier. This is supported by the high values of the Bi$_2$Se$_3$ induced gap and of I$_c$R$_n$ (I$_c$ critical current, R$_n$ normal resistance of the junction) product both of the order of 160 $μ$eV, a value close to the Al gap. The devices present an extremely low relative resistance noise below 1$\times$10$^{-12}$ $μ$m$^2$/Hz comparable to the best Al tunnel junctions, which indicates a high stability in the transmission coefficients of transport channels. The ideal Al/Bi$_2$Se$_3$ interface properties, perfect transparency for Cooper pair transport in conjunction with low resistive noise make these junctions a suitable platform for further studies of the induced topological superconductivity and Majorana bound states physics.

description: Household water insecurity is a pressing problem in developing countries. Unsustainable water withdrawal is increasing due to population growth, industrialization, urbanization, and increasing agricultural production which leads to various problems. The number of countries facing problems of water scarcity and insufficient water supply is rising. Already there are 1.2 billion people without access to clean water, many of whom live in 20 developing countries classified as ‘water scarce’. Typically it is found in these countries, that the poor pay particularly high prices for water and are most water insecure. Progress towards water security can be made only if there is a more comprehensive understanding of the interactions among waters’ various characteristics and functions. Water is not only a natural resource, but also an economic commodity, and a human consumption good or entitlement. The problems of water insecurity can be grouped under three main headings: availability, access and usage. In the framework of a multidisciplinary approach to the analysis of water problems, the paper elaborates on these three elements, defining sectoral and cross-sectoral knowledge gaps. The paper concludes with a research agenda in support of improved policy design and action.
Charmonium polarization in e^+e^- and heavy ion collisions

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

description: In e^+e^- annihilation at \sqrt{s}=10.6 GeV Belle Collaboration found, that J/psi mesons are predominantly produced in association with an extra \bar{c}c pair. The possible mechanisms of J/psi production are discussed and the probability of the associate production of \bar{c}c pair is estimated. The choice between these mechanisms can be done by measuring J/psi polarization. It is suggested, that in case of heavy ion collisions one may expect remarkable transverse polarization of produced J/psi, if quark-gluon plasma if formed. The measurement of asymmetry of e^+e^-(μ^+μ^-) angular distribution in J/psi-> e^+e^-(μ^+μ^-) decay is a useful tool for detection of quark-gluon plasma formation in heavy ion collisions.

description: We consider a family of compact manifolds which shrinks with respect to an appropriate parameter to a graph. The main result is that the spectrum of the Laplace-Beltrami operator converges to the spectrum of the (differential) Laplacian on the graph with Kirchhoff boundary conditions at the vertices. On the other hand, if the the shrinking at the vertex parts of the manifold is sufficiently slower comparing to that of the edge parts, the limiting spectrum corresponds to decoupled edges with Dirichlet boundary conditions at the endpoints. At the borderline between the two regimes we have a third possibility when the limiting spectrum can be described by a nontrivial coupling at the vertices.
