description: Current-voltage characteristics of a spintromechanical device, in which spin-polarized electrons tunnel between magnetic leads with anti-parallel magnetization through a single level movable quantum dot, are calculated. New exchange- and electromechanical coupling-induced (spin-polaronic) effects that determine strongly nonlinear current-voltage characteristics were found. In the low-voltage regime of electron transport the voltage-dependent and exchange field-induced displacement of quantum dot towards the source electrode leads to nonmonotonic behavior of differential conductance that demonstrates the lifting of spin-polaronic effects by electric field. At high voltages the onset of electron shuttling results in the drop of current and negative differential conductance, caused by mechanically-induced increase of tunnel resistivities and exchange field-induced suppression of spin-flips in magnetic field. The dependence of these predicted spin effects on the oscillations frequency of the dot and the strength of electron-electron correlations is discussed.

description: The near-threshold photoproduction of $J/ψ$ is regarded as one golden process to unveil the nucleon mass structure, pentaquark state involving the charm quarks, and the poorly constrained gluon distribution of the nucleon at large $x$ ($>0.1$). In this paper, we present an analysis of the current experimental data under a two-gluon exchange model, which shows a good consistency. Using a parameterized function form with three free parameters, we have determined the nucleonic gluon distribution at the $J/ψ$ mass scale. Moreover, we predict the differential cross section of the electroproduction of $J/ψ$ as a function of the invariant mass of the final hadrons $W$, at EicC, as a practical application of the model and the obtained gluon distribution. According to our estimation, thousands of $J/ψ$ events can be detected per year on EicC near the threshold. Therefore, the relevant experimental measurements are suggested to be carried out on EicC.

description: Background: Marijuana blunts, which are tobacco cigar wrappers filled with marijuana, are commonly smoked in the US as a means of cannabis use. The use of marijuana blunts presents toxicity concerns because the smoke contains both marijuana-related and tobacco-related chemicals. Thus, it is important to understand the chemical composition of mainstream smoke (MSS) from marijuana blunts. This study demonstrates the ability to detect and identify chemical constituents exclusively associated with blunt MSS in contrast to tobacco cigar MSS (designated as ‘new exposures’) through non-targeted chemical analysis. Methods: Samples collected separately from blunt MSS and tobacco cigar MSS were analyzed using two-dimensional gas chromatography–time-of-flight mass spectrometry (GC × GC-TOFMS). Results and Discussion: Two new exposures, which likely represent only a subset of all new exposures, were identified by evaluating the data from thousands of detected signals and then confirming selected compound identities in analyses using authentic chemical standards. The two confirmed new exposures, mellein and 2-phenyl-2-oxazoline, are not cannabinoids and, to the best of our knowledge, have not been previously reported in association with cannabis, tobacco, or smoke of any kind. In addition, we detected and quantified three phenols (2-, 3-, and 4-ethylphenol) in blunt MSS. Given the toxicity of phenols, quantifying the levels of other phenols could be pursued in future research on blunt MSS. Conclusion: This study shows the power and utility of GC × GC-TOFMS as a methodology for non-targeted chemical analysis to identify new chemical exposures in blunt MSS and to provide data to guide further investigations of blunt MSS.

These corrections are important ingredients for next-to-next-to-leading logarithmic predictions of various observables related to the decays B -> X_s l^+ l^- in these models. In scenarios with moderate values of tan(beta) neutral Higgs boson contributions can be safely neglected for e,mu. Therefore we concentrate on the contributions mediated by charged Higgs bosons.

description: In this work, the room temperature polar vapor sensing behavior of two dimentional (2D) heterojunction Graphene-TiS3 materials and TiS3 nanoribbons is investigated. TiS3 nanoribbons were synthesized via chemical vapor transport (CVT) and their structure was investigated by scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), energy dispersive X- ray spectroscopy (EDS), X-ray diffraction (XRD), Raman spectroscopy and Fourier transform infrared spectroscopy (FT-IR) analysis. The gas sensing performance of the TiS3 nanoribbons was assessed through the observed changes in their electronic behavior. Sensing devices were fabricated with gold contacts and with lithographically patterned graphene (Gr) electrodes in a 2D heterojunction Gr-TiS3-Gr architecture.. It is observed that the gold contacted TiS3 device has a rather linear I-V behavior while the Gr-TiS3-Gr heterojunction forms a contact with a higher Schottky barrier (250 meV). I-V responses of the sensors were recorded at room temperature with a relative humidity of 55% and for different ethanol vapor concentrations (varying from 2 to 20 ppm). I-V plots indicated an increase in the resistance of Gr-TiS3-Gr by the adsorption of water and ethanol molecules with relatively high sensing response (~3353% at 2 ppm). Our results reveal that selective and stable responses to a low concentration of ethanol vapor (2 ppm) can be achieved at room temperature with transient response and recovery times of around 6 s and 40 s, respectively. Our proposed design demonstrate a new approach for selective molecular recognition using polar interactions between analyte vapors and heterojunctions of 2D-materials.

Using small angle neutron scattering, we have observed a square vortex lattice with the nearest-neighbors oriented at 45$^{\circ}$ from the Cu-O bond direction, which is consistent with theories based on the d-wave superconducting gap. However, the square symmetry persists down to unusually low magnetic fields. Moreover, the diffracted intensity from the vortex lattice is found to decrease rapidly with increasing magnetic field.

description: Companies and individuals produce numerous tabular data. The objective of this position paper is to draw up the challenges posed by the automatic integration of data in the form of tables so that they can be cross-analyzed. We provide a first automatic solution for the integration of such tabular data to allow On-Line Analysis Processing. To fulfil this task, features of tabular data should be analyzed and the challenge of automatic multidimensional schema generation should be addressed. Hence, we propose a typology of tabular data and discuss our idea of an automatic solution.

description: This article studies the estimation of the causal effect of a time-varying treatment on time-to-an-event or on some other continuously distributed outcome. The paper applies to the situation where treatment is repeatedly adapted to time-dependent patient characteristics. The treatment effect cannot be estimated by simply conditioning on these time-dependent patient characteristics, as they may themselves be indications of the treatment effect. This time-dependent confounding is common in observational studies. Robins [(1992) Biometrika 79 321--334, (1998b) Encyclopedia of Biostatistics 6 4372--4389] has proposed the so-called structural nested models to estimate treatment effects in the presence of time-dependent confounding. In this article we provide a conceptual framework and formalization for structural nested models in continuous time. We show that the resulting estimators are consistent and asymptotically normal. Moreover, as conjectured in Robins [(1998b) Encyclopedia of Biostatistics 6 4372--4389], a test for whether treatment affects the outcome of interest can be performed without specifying a model for treatment effect. We illustrate the ideas in this article with an example.

description: Currently almost all energy is provided by fossil fuels that increase greenhouse gas emissions contributing to global warming. These emissions can be reduced with the use of renewable energy produced from biomass such a livestock manure. The manure is raw material for production of electricity and thermal energy. Anaerobic digestion of waste can reduce emissions by capturing methane, a greenhouse gas produced by waste in facilities large and small scale. The South Central region of the state of Chihuahua has the potential for renewable energy production from biomass and waste are approximately 58,000 head of cattle, valuing a daily output of 2,900 m3 of sewage and 10,000 m3 of waste water can cause environmental problems. The estimated biogas production was 1.73 m3 of biogas / cow / day, with an estimated total production of biogas in the region of 25,717,352 and 50,722,754 m3/year kwh/año save up to $ 45.143 million pesos in electricity. Reductions are estimated to 361.843 tons of CO2-Eq. Proposed technologies to small and large scales. The development of renewable energy technologies opens the opportunity for additional revenue-generating waste in the production of electricity or thermal energy, reducing environmental problems may make feasible the adoption of technology to small and large scale for producers.

description: The development of effective leaders and leadership behaviour may be a prominent concern in organizations of all kinds. We review the hypothetical and observed sources of information on leader and leadership development that specialize in Leadership Qualities. Compared to the reasonably long history of leadership research and theory, the systematic study of leadership development features a moderately short history of research as the need for study on Systematic Leadership development was not considered important. We study and observe interpersonal and intrapersonal issues associated with the phenomena that develop during the quest of effective leadership, describe how development emerges by giving importance to the collection of overall feedback processes, review studies of leadership development and analytical issues in leader and leadership development research.

description: The feeding and the shelter are considered basic needs of the man and one of the options to satisfy them is through the lambs which contribute to cover them with their meat, wool and skin. For the analysis of the yield a flock took itself from twenty females and a stallion one of Pelibuey race and was developed in conditions of semiestabulado and artificial prairie with oats and rye grass in the north of the State of Sonora.Several indicators were taken to carry out the determination of the yield taking in first instance the capital of work, point of balance, sensitivity analysis as well as the relation benefit-cost. In the case of first the amount of 109.650,44 like so was determined whereas the balance point obtains as of the second period of 270 days showing little sensitivity the changes of the sale price of the young since the ninety percent of them is realised like registry cattle and the rest to commercial prices and; the relation benefit-cost was of 1.98. These indicators show that the growing and operation of lambs under these conditions reveals an acceptable yield for the producers.

description: CMasher is a Python package that provides a curated collection of scientific colormaps, showcased in the online documentation (https://cmasher.readthedocs.io). The colormaps in CMasher are all designed to be perceptually uniform sequential using the 'viscm' package; most of them are color-vision deficiency friendly; and they cover a wide range of different color combinations to accommodate for most applications. It aims to provide several alternatives to commonly used colormaps, like 'chroma' and 'rainforest' for 'jet'; 'sunburst' for 'hot'; 'neutral' for 'binary'; and 'fusion' and 'redshift' for 'coolwarm'. With CMasher, I hope to help others with picking the correct colormap for the job.

In the classical case (bits), this means the possible marginal distributions of a probability distribution on a finite number of binary variables; we give necessary and sufficient conditions for a set of probability distributions on all proper subsets of the variables to be the marginals of a single distribution on the full set. In the quantum case (qubits), we consider mixed states of subsets of a set of qubits; in the case of three qubits, we find quantum Bell inequalities -- necessary conditions for a set of two-qubit states to be the reduced states of a single mixed state of three qubits. We conjecture that these conditions are also sufficient.

description: We investigate signatures of magnetic fields and activity at the surface and in the prominence system of the ultra-rapid rotator V530 Per, a G-type solar-like member of the young open cluster $α$~Persei. This object has a rotation period shorter than all stars with available magnetic maps. With a time-series of spectropolarimetric observations gathered with ESPaDOnS over 2 nights on the CFHT, we reconstruct the surface brightness and large-scale magnetic field of V530 Per using the Zeeman-Doppler imaging method, assuming an oblate stellar surface. We also estimate the short term evolution of the brightness distribution through latitudinal differential rotation. Using the same data set, we finally map the spatial distribution of prominences through tomography of the Hαemission. The brightness map is dominated by a large, dark spot near the pole, accompanied by a complex distribution of bright and dark features at lower latitudes. The magnetic field map is reconstructed as well, most of the large-scale magnetic field energy is stored in the toroidal field component. The main radial field structure is a positive region of about 500 G, at the location of the dark polar spot. The brightness map of V530 Per is sheared by solar-like differential rotation, with a roughly solar value for the difference in rotation rate between the pole and equator. \halpha~is observed in emission, and is mostly modulated by the stellar rotation period. The prominence system is organized in a ring at the approximate location of the co-rotation radius, with significant evolution between the two observing nights. V530 Per is the first example of a solar-type star to have its surface magnetic field and prominences mapped together, which will bring important observational constraints to better understand the role of slingshot prominences in the angular momentum evolution of the most active stars.

description: Quantitative magnetic resonance imaging (qMRI) derives tissue-specific parameters -- such as the apparent transverse relaxation rate R2*, the longitudinal relaxation rate R1 and the magnetisation transfer saturation -- that can be compared across sites and scanners and carry important information about the underlying microstructure. The multi-parameter mapping (MPM) protocol takes advantage of multi-echo acquisitions with variable flip angles to extract these parameters in a clinically acceptable scan time. In this context, ESTATICS performs a joint loglinear fit of multiple echo series to extract R2* and multiple extrapolated intercepts, thereby improving robustness to motion and decreasing the variance of the estimators. In this paper, we extend this model in two ways: (1) by introducing a joint total variation (JTV) prior on the intercepts and decay, and (2) by deriving a nonlinear maximum \emph{a posteriori} estimate. We evaluated the proposed algorithm by predicting left-out echoes in a rich single-subject dataset. In this validation, we outperformed other state-of-the-art methods and additionally showed that the proposed approach greatly reduces the variance of the estimated maps, without introducing bias.

description: The dynamical cluster-decay model (DCM) is developed further for the decay of hot and rotating compound nuclei (CN) formed in light heavy-ion reactions. The model is worked out in terms of only one parameter, namely the neck-length parameter, which is related to the total kinetic energy TKE(T) or effective Q-value $Q_{eff}(T)$ at temperature T of the hot CN, defined in terms of the both the light-particles (LP), with $A \leq$ 4, Z $\leq$ 2, as well as the complex intermediate mass fragments (IMF), with $4 < A < 20, Z > 2$, is considered as the dynamical collective mass motion of preformed clusters through the barrier. Within the same dynamical model treatment, the LPs are shown to have different characteristics as compared to the IMFs. The systematic variation of the LP emission cross section $σ_{LP}$, and IMF emission cross section $σ_{IMF}$, calculated on the present DCM match exactly the statistical fission model predictions. It is for the first time that a non-statistical dynamical description is developed for the emission of light-particles from the hot and rotating CN. The model is applied to the decay of $^{56}$Ni formed in the $^{32}$S + $^{24}$Mg reaction at two incident energies E$_{c.m.}$ = 51.6 and 60.5 MeV. Both the IMFs and average $\bar{TKE}$ spectra are found to compare reasonably nicely with the experimental data, favoring asymmetric mass distributions. The LPs emission cross section is shown to depend strongly on the type of emitted particles and their multiplicities.

description: Fractional calculus is a couple of centuries old, but its development has been less embraced and it was only within the last century that a program of applications for physics started. Regarding quantum physics, it has been only in the previous decade or so that the corresponding literature resulted in a set of defying papers. In such a context, this manuscript constitutes a cordial invitation, whose purpose is simply to suggest, mostly through a heuristic and unpretentious presentation, the extension of fractional quantum mechanics to cosmological settings. Being more specific, we start by outlining a historical summary of fractional calculus. Then, following this motivation, a (very) brief appraisal of fractional quantum mechanics is presented, but where details (namely those of a mathematical nature) are left for literature perusing. Subsequently, the application of fractional calculus in quantum cosmology is introduced, advocating it as worthy to consider: if the progress of fractional calculus serves as an argument, indeed useful consequences will also be drawn (to cite from Leibnitz). In particular, we discuss different difficulties that may affect the operational framework to employ, namely the issues of minisuperspace covariance and fractional derivatives, for instance. An example of investigation is provided by means of a very simple model. Concretely, we restrict ourselves to speculate that with minimal fractional calculus elements, we may have a peculiar tool to inspect the flatness problem of standard cosmology. In summary, the subject of fractional quantum cosmology is herewith proposed, merely realized in terms of an open program constituted by several challenges.

description: Aloe Vera is the base of a very lucrative business around the world, in which Mexico participates as the main Aloe Vera raw materials producer and exporter country. For the perishable nature of Aloe Vera raw materials, they go under a stabilization process that fulfills the final consumer requirements. Many of the companies certify their raw materials, processes and final products in order to guarantee to the final consumer the origin, purity, and product content, besides the ethical strictness of their promotional and commercial information. The certifying council (International Aloe Science Council) express in their promotion that certified companies are more competitive than those that don't certify their products. However, since the lack of evidences of this fact and the high cost that represents this certification for the small companies, a study was made to determine through the consultation of the Aloe Vera industry directives in Mexico, if such effect is perceived. The study information was obtained by means of questionnaires and interviews with directive of companies of Tamaulipas, Yucatan, Durango and the Texas's Valley. The results showed that the factors with more impact in the competitiveness of Aloe Vera industry in Mexico are product quality and capacity of the company directives. In general 90% of the sample agrees there is a direct relationship between raw materials, products and processes certification and the competitiveness of the companies. In consequence this answer gave elements to support the hypothesis of the existence of a relationship among the considered variables.

description: We discuss different sources of hadron correlations in relativistic heavy ion collisions. We show that correlations among partons in a quasi-thermal medium can lead to the correlated emission of hadrons by quark recombination and argue that this mechanism offers a plausible explanation for the dihadron correlations in the few GeV/c momentum range observed in Au+Au collisions at RHIC.

description: 3D photography is a new medium that allows viewers to more fully experience a captured moment. In this work, we refer to a 3D photo as one that displays parallax induced by moving the viewpoint (as opposed to a stereo pair with a fixed viewpoint). 3D photos are static in time, like traditional photos, but are displayed with interactive parallax on mobile or desktop screens, as well as on Virtual Reality devices, where viewing it also includes stereo. We present an end-to-end system for creating and viewing 3D photos, and the algorithmic and design choices therein. Our 3D photos are captured in a single shot and processed directly on a mobile device. The method starts by estimating depth from the 2D input image using a new monocular depth estimation network that is optimized for mobile devices. It performs competitively to the state-of-the-art, but has lower latency and peak memory consumption and uses an order of magnitude fewer parameters. The resulting depth is lifted to a layered depth image, and new geometry is synthesized in parallax regions. We synthesize color texture and structures in the parallax regions as well, using an inpainting network, also optimized for mobile devices, on the LDI directly. Finally, we convert the result into a mesh-based representation that can be efficiently transmitted and rendered even on low-end devices and over poor network connections. Altogether, the processing takes just a few seconds on a mobile device, and the result can be instantly viewed and shared. We perform extensive quantitative evaluation to validate our system and compare its new components against the current state-of-the-art.

Joint MPEG-2/H.264 scalable coding and enhancements to H.264 intra-mode prediction
Creators: name: Storey, Duane Thomas
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis, several enhancements and optimizations related to H. 264, the latest and most advanced video standard, are explored. The first part of this work involves the investigation of a new spatial scalability scheme involving MPEG-2 as a base-layer and H.264 as a spatial enhancement-layer. This scheme does not involve any bitstream modifications, and can be configured using off-the-shelf components. While simplistic, this scheme results in bitrate reductions for the tested CIF sequences of approximately 50% (depending on the quality of the base-layer) and bitrate reductions on the order of 20% for high-definition 720p imagery. An alternate scheme is also proposed that extends the H.264 bitstream syntax by adding a new 4x4 Intra-block prediction mode. For Intra-frames, bitrate reductions on the order of 25% are possible depending on the quality of the base-layer. Since this scheme can also choose to ignore distorted base-layer blocks, it is not subject to the large bit-penalty associated with low-bitrate base-layer sequences demonstrated using the first proposed scheme. Finally, a modified Intra-mode prediction scheme is proposed for H.264 that involves forming a real-time estimate of the joint probability distribution functions for the Intra prediction modes. Using these distributions, it is possible to obtain an increase in prediction accuracy of approximately 50% over the default H.264 prediction method.

description: A renormalization group (RG) improvement of the Einstein-Hilbert action is performed which promotes Newton's constant and the cosmological constant to scalar functions on spacetime. They arise from solutions of an exact RG equation by means of a ``cutoff identification'' which associates RG scales to the points of spacetime. The resulting modified Einstein equations for spherically symmetric, static spacetimes are derived and analyzed in detail. The modifications of the Newtonian limit due to the RG evolution are obtained for the general case. As an application, the viability of a scenario is investigated where strong quantum effects in the infrared cause Newton's constant to grow at large (astrophysical) distances. For two specific RG trajectories exact vacuum spacetimes modifying the Schwarzschild metric are obtained by means of a solution-generating Weyl transformation. Their possible relevance to the problem of the observed approximately flat galaxy rotation curves is discussed. It is found that a power law running of Newton's constant with a small exponent of the order $10^{-6}$ would account for their non-Keplerian behavior without having to postulate the presence of any dark matter in the galactic halo.

description: While driving in regions where animals are regularly present, it’s not unexpected to end up in an accident. Both wild and domestic animals might be outside and can keep running into the street. Normally, a driver’s first nature is to swerve to abstain from hitting the animal; however, that can have wrecking results, such as losing control of the vehicle and enduring genuine wounds. Swerving can deliver a domino impact, making the driver strike another vehicle or object, which can prompt far more atrocious outcomes, similar to the vehicle moving over or genuine damage to different drivers out on the road. It’s essential to avoid such accidents and protect animals as well. To overcome this new method is proposed in this paper which includes a circuit generating Ultrasonic waves. It can be used as pest repellents. For generating ultrasonic waves of high frequency a generator using 555 timers is employed. These waves are designed to produce an extremely highfrequency sound that is beyond what humans can hear. Ultrasound is used to bring about enough irritation in animals and make them stay away from highways.

description: Locomotion of bacteria by actin polymerization, and in vitro motion of spherical beads coated with a protein catalyzing polymerization, are examples of active motility. Starting from a simple model of forces locally normal to the surface of a bead, we construct a phenomenological equation for its motion. The singularities at a continuous transition between moving and stationary beads are shown to be related to the symmetries of its shape. Universal features of the phase behavior are calculated analytically and confirmed by simulations. Fluctuations in velocity are shown to be generically non-Maxwellian and correlated to the shape of the bead.
