Mechanochemical synthesis

description: Tetrahedrite-based compounds are considered a promising thermoelectric material. The tetrahedrite-tennantite series, that can be generically expressed as Cu6[Cu4(Fe,Zn)2](Sb,As)4S13, is one of the most abundant sulfosalt minerals in the earth’s crust. The Iberian Pyrite Belt (IPB), located in southern Portugal and Spain, is the host of the largest concentration of massive sulfide deposits worldwide, where the tetrahedrite-tennantite series mineral is one of the constituents. In this work we evaluate the effectiveness of combining synthetic tetrahedrite (ST) with tetrahedrite-tennantite ore samples (TTOS) in the mechanochemical synthesis (MCS) process of tetrahedrite-based compounds. The ore samples were collected from two distinct deposits within the Portuguese part of the IPB, the Neves Corvo mine and the abandoned Barrigão copper mine. The ST, also produced by MCS, were mixed with the TTOS in different mass ratios ranging from 20-80%. The influence of the chemical composition and phase constitution of the ore samples and of the mixing ratios will be presented in relation to the micro-structural properties of the obtained materials. The results here described are part of a broader study dedicated to the development of energy-harvesting applications based on tetrahedrite.

description: Over the last eight years, a rich dataset of mid-infrared CH4 observations from the TEXES instrument at IRTF has been used to characterize the thermal evolution of Jupiter's stratosphere. These data were used to produce vertically-resolved temperature maps between latitudes of 50°S and 50°N, allowing us to track approximately two periods of Jupiter's quasi-quadrennial oscillation (QQO). During the first five years of observations, the QQO has a smooth sinusoidal pattern with a period of 4.0$\pm$0.2 years and an amplitude of 7$\pm$1 K at 13.5 mbar (our region of maximum sensitivity). In 2017, we note an abrupt change to this pattern, with the phase being shifted backwards by ~1 year. Searching for possible causes of this QQO delay, we investigated the TEXES zonally-resolved temperature retrievals and found that in May/June 2017, there was an unusually warm thermal anomaly located at a latitude of 28°N and a pressure of 1.2 mbar, moving westward with a velocity of 19$\pm$4 m/s. We suggest that there may be a link between these two events.

description: Lead sulfide (PbS) quantum dot (QD) photovoltaics have reached impressive efficiencies of 12%, making them particularly promising for future applications. Like many other types of emerging photovoltaic devices, their environmental instability remains the Achilles heel of this technology. In this work, we demonstrate that the degradation processes in PbS QDs which are exposed to oxygenated environments are tightly related to the choice of ligands, rather than their intrinsic properties. In particular, we demonstrate that while 1,2-ethanedithiol (EDT) ligands result in significant oxidation of PbS, lead iodide/lead bromide (PbX2) coated PbS QDs show no signs of oxidation or degradation. Consequently, since the former is ubiquitously used as a hole extraction layer in QD solar cells, it is predominantly responsible for the device performance evolution. The oxidation of EDT-PbS QDs results in a significantly reduced effective QD size, which triggers two competing processes: improved energetic alignment that enhances electron blocking, but reduced charge transport through the layer. At early times, the former process dominates, resulting in the commonly reported, but so far not fully explained initial increase in performance, while the latter governs the onset of degradation and deterioration of the photovoltaic performance. Our work highlights that the stability of PbS quantum dot solar cells can be significantly enhanced by an appropriate choice of ligands for all device components.
Non-linear susceptibility in glassy systems: a probe for cooperative dynamical length scales

description: We argue that for generic systems close to a critical point, an extended Fluctuation-Dissipation relation connects the low frequency non-linear (cubic) susceptibility to the four-point correlation function. In glassy systems, the latter contains interesting information on the heterogeneity and cooperativity of the dynamics. Our result suggests that if the abrupt slowing down of glassy materials is indeed accompanied by the growth of a cooperative length ell, then the non-linear, 3 omega response to an oscillating field should substantially increase and give direct information on the temperature (or density) dependence of ell. The analysis of the non-linear compressibility or the dielectric susceptibility in supercooled liquids, or the non-linear magnetic susceptibility in spin-glasses, should give access to a cooperative length scale, that grows as the temperature is decreased or as the age of the system increases. Our theoretical analysis holds exactly within the Mode-Coupling Theory of glasses.

Matched filter bounds for fast fading Rician channels
Creators: name: Dinesh, Vaibhav
Publisher: name: University of British Columbia
Year: 2009

description: A new matched filter bound (MFB) for a dispersive Rician fading channel with unrestricted normalized Doppler rate is presented. Analytical expressions are derived for BPSK modulation. The channel model is based on the standard linear time varying filter. The BER performance, in general, is found to improve with an increase in the fading rate due to the inherent diversity present within a single pulse. The shape of the transmitted pulse is shown to affect the BER in fast fading conditions. It has been found that the specular component improves the BER at lower fading rates; for very high fading rates, the implicit diversity effect becomes dominant in diminishing the effect of fading. Discrete (two and three beam) models are assumed for the dispersive channel. The error bounds for the three-beam model are derived as a function of the inter-beam delay and correlation parameters. In general, the delay spread was found to result in lowering the BER for both the slow and fast fading cases when the fading in the beams is uncorrelated. In the two-beam frequency selective case, the BER is very sensitive to the degree of beam overlap. Finally, assuming errors in estimating the channel fading waveform, the BER for a non-ideal receive filter is obtained. It was observed that, for the specified model, the system degradation is higher for phase mismatches than for amplitude mismatches for a given error variance.

The analysis is based on a maximum likelihood ratio test using the probability density function for each event rather than requiring an a priori choice of a fixed angular bin size. The search is extended to the combined data set of HiRes data above 10^19 eV and AGASA data above 4.0 10^19 eV. In both cases, no statistically significant clustering of events consistent with a point source is found.

description: Estimates of country-level loan default distributions are developed and used in a loan guarantee model to value the contingent liability of USDA's General Sales Manager (GSM) export credit guarantee portfolio. The results quantify the relationship between increasing guarantee coverage and the resulting actuarial liability to the government. Optimal coverage levels and optimal country-level allocations are determined for given policy objectives and coverage totals. Findings reveal that the government's allocation of country guarantees is risk-inefficient; and guidance is provided for making risk-efficient allocations for any program size.

 Comments. For a long time Donacocia was credited to GISTEL (1857b,c) with a single included species, Donacocia aenea Gistel, 1857, considered thus the type species (MON- RÓS & BECHYNÉ 1956, JOLIVET 1970, SEENO & WILCOX 1982). ASKEVOLD (1990, 1991) placed Donacocia in synonymy with Plateumaris C. G. Thomson, 1859 (see also RILEY et al. 2003: 187). LÖBL & SILFVERBERG (2010) found that Donacocia was described already in 1856 (GISTEL 1856a), designated Donacia brevicornis as the type species and re-established the synonymy of Donacocia with Donacia. Recently, KIPPENBERG (2015) re-arranged the subgeneric system of Donacia and used Donacocia as a valid subgenus.

description: An arbitrary order finite difference method for curved boundary domains with Cartesian grid is proposed. The technique handles in a universal manner Dirichlet, Neumann or Robin condition. We introduce the Reconstruction Off-site Data (ROD) method, that transfers in polynomial functions the information located on the physical boundary. Three major advantages are: (1) a simple description of the physical boundary with Robin condition using a collection of points; (2) no analytical expression (implicit or explicit) is required, particularly the ghost cell centroids' projection are not needed; (3) we split up into two independent machineries the boundary treatment and the resolution of the interior problem, coupled by the the ghost cell values. Numerical evidences based on the simple 2D convection-diffusion operators are presented to prove the ability of the method to reach at least the 6th-order with arbitrary smooth domains.

description: A plethora of research in recent years has been devoted to estimating consumer demand for genetically modified food, an important piece of information needed to create appropriate public policy. To examine this body of work, a meta-analysis was conducted of 25 studies that, in aggregate, report 57 valuations for GM food. Findings indicate as much as 89% of the variation in existing value estimates for genetically modified food can be explained by an econometric model that controls for (a) the characteristics of the sample of consumers studied, (b) the method for eliciting consumers' valuation, and (c) characteristics of the food being valued. Each of these factors has a statistically significant effect on estimated premiums for non-GM food. Results of this study effectively summarize the extant literature on consumer demand for genetically modified food and permit the creation of some stylized facts that are not conditional on the results of one particular study. This paper also illustrates the effect of methodological choices on valuation estimates and reports a model which allows researchers and policy makers to quickly generate valuation measures for use in marketing or cost benefit analysis.

The paper develops a state specific, time-series environmental stringency measure and introduces instrumental variables to control for the possible endogeneity bias between livestock production decisions and regulatory stringency. The results indicate that differences in the severity of environmental regulations facing livestock producers have had a significant influence on production decisions in the dairy, and particularly the hog sector.

description: The Doppler method of exoplanet detection has been extremely successful, but suffers from contaminating noise from stellar activity. In this work a model of a rotating star with a magnetic field based on the geometry of the K2 star Epsilon Eridani is presented and used to estimate its effect on simulated radial velocity measurements. A number of different distributions of unresolved magnetic spots were simulated on top of the observed large-scale magnetic maps obtained from eight years of spectropolarimetric observations. The radial velocity signals due to the magnetic spots have amplitudes of up to 10 m s$^{-1}$, high enough to prevent the detection of planets under 20 Earth masses in temperate zones of solar type stars. We show that the radial velocity depends heavily on spot distribution. Our results emphasize that understanding stellar magnetic activity and spot distribution is crucial for detection of Earth analogues.

description: In this paper we address the problem of the calculation of the mean first passage time (MFPT) on generic graphs. We focus in particular on the mean first passage time on a node 's' for a random walker starting from a generic, unknown, node 'x'. We introduce an approximate scheme of calculation which maps the original process in a Markov process in the space of the so-called rings, described by a transition matrix of size O(ln N / ln X ln N / ln), where N is the size of the graph and the average degree in the graph. In this way one has a drastic reduction of degrees of freedom with respect to the size N of the transition matrix of the original process, corresponding to an extremely-low computational cost. We first apply the method to the Erdos-Renyi random graph for which the method allows for almost perfect agreement with numerical simulations. Then we extend the approach to the Barabasi-Albert graph, as an example of scale-free graph, for which one obtains excellent results. Finally we test the method with two real world graphs, Internet and a network of the brain, for which we obtain accurate results.

description: Eastern Region technical attachment (National Weather Service (U.S.)) ; 2015-03
description: Ground-truth observations play a crucial role in the issuance of National Weather Service (NWS) Severe Thunderstorm Warnings for severe hail.  Many radar warning techniques for severe hail are created off of these ground-based observations, which are correlated to quantitative threshold values that were observed at the time of severe hail occurrence.  With the inclusion of Polarimetric radar (PR) data into NWS warning operations, the sampling of hydrometeors in both the horizontal and vertical provides the opportunity to discern amongst different hydrometeor types in the mixed phase region of a thunderstorm updraft.  Used in conjunction with an understanding of thunderstorm dynamics and the surrounding thermodynamic and kinematic environment, PR data can provide the ability to forecast the occurrence of severe hail at the ground early in the lifecycle of a thunderstorm.  A proposed strategy and decision aid are introduced that outline a qualitative conceptual forecast approach to the issuance of Severe Thunderstorm Warnings for severe hail using PR data.  Applications of this approach are provided for two thunderstorms that occurred during the 21 May 2013 severe weather event across the NWS Albany, New York county warning area.

The Drell--Yan asymmetries turn out to be large, in the range 20--40%. Measuring these asymmetries would provide the cleanest determination of the quark transversity distributions.

description: We study geometric presentations of braid groups for particles that are constrained to move on a graph, i.e. a network consisting of nodes and edges. Our proposed set of generators consists of exchanges of pairs of particles on junctions of the graph and of certain circular moves where one particle travels around a simple cycle of the graph. We point out that so defined generators often do not satisfy the braiding relation known from 2D physics. We accomplish a full description of relations between the generators for star graphs where we derive certain quasi-braiding relations. We also describe how graph braid groups depend on the (graph-theoretic) connectivity of the graph. This is done in terms of quotients of graph braid groups where one-particle moves are put to identity. In particular, we show that for $3$-connected planar graphs such a quotient reconstructs the well-known planar braid group. For $2$-connected graphs this approach leads to generalisations of the Yang-Baxter equation. Our results are of particular relevance for the study of non-abelian anyons on networks showing new possibilities for non-abelian quantum statistics on graphs.

description: A competitive partial-equilibrium spatial model with heterogeneous goods is constructed to evaluate effects of the removal of tariffs, tariff-rate quotas, and sanitary regulations on world poultry trade. The model distinguishes between "highvalue" (mostly white meat) and "low-value" (mostly dark meat) poultry products and simulates the trade flows among eight exporting and importing countries and regions. Removing all barriers simultaneously has a larger impact on trade than removing only tariffs and tariff-rate quotas. Imposition of sanitary barriers against U.S. products by Russia shifts trade flows, but does not have large net impacts on U.S. producers.

description: We present a general interpolation theory for the phenomenological effects of thermal fluctuations in superconductors. Fluctuations are described by a simple gauge invariant extension of the gaussian effective potential for the Ginzburg-Landau static model. The approach is shown to be a genuine variational method, and to be stationary for infinitesimal gauge variations around the Landau gauge. Correlation and penetration lengths are shown to depart from the mean field behaviour in a more or less wide range of temperature below the critical regime, depending on the class of material considered. The method is quite general and yields a very good interpolation of the experimental data for very different materials.

We used 97 spectra acquired with CORALIE and 230 spectra acquired with HARPS to characterize the radial velocity behavior of Beta-Pictoris and to infer constraints on the presence of a planet close to this star. With these data, we were able to exclude the presence of an inner giant planet (2 MJup at a distance to the star of 0.05 AU, 9 MJup at 1 AU). We also discuss the origin of the observed radial velocity variations in terms of Delta-Scuti type pulsations.

description: This analysis extends previous work on green insurance by proposing a mechanism that offers a stronger adoption incentive and is applicable to heterogeneous populations and non-binary adoption decisions. Endogenous learning about the new technology is incorporated, and empirically calibrated simulation results are presented for the case of reduced-phosphorus dairy diets. Results show that the mechanism has a significant impact on behavior and may incur no net cost for the regulator when an insurance premium is charged. Conditions under which a green payment mechanism may be preferable to green insurance also are discussed.

Specifically, roll angle estimation errors as small as 0.1 degrees can cause noticeable gain errors of 1 dB or more. Beam-stitching techniques exist that can reduce these errors in the beam overlap region; however, accurate roll information is required for optimum radiometric calibration across the entire range swath. Current roll angle estimation algorithms do not provide consistent results even on routine scenes. These algorithms are susceptible to uncertainties in the range beam patterns, overall scene a°, and other system variables. Currently, the Canadian Data Processing Facility does not implement an automated roll angle estimator. Compensation for range gain errors is performed in the post-processing stage. This thesis proposes a new data acquisition method, in which signal data is obtained during the beam switchover by transmitting pulses through one beam and receiving them with another beam. This "hybrid data" is then used in a new (hybrid peak detection) and modified (three beam) algorithm to provide a more accurate and robust roll estimate. Algorithms using this hybrid data are more tolerant to lower mean scene σ°, gain uncertainty, and other variables than algorithms using normal data. As this data is not currently acquired, the algorithm is tested using simulated data. The logistics of acquiring hybrid data are also explored. The implementation of hybrid data acquisition on RADARSAT-1 would not require any significant software changes. The effects of various roll angle estimation errors on different beam combinations are simulated. The new data and algorithms offer significant potential for improving roll estimates. Results suggest that the three beam algorithm can generally tolerate 3-4 dB lower σ° and 0.2 to 0.4 dB more uncertainty in the beam pattern gain than a current algorithm, while meeting required radiometric accuracy. The hybrid peak detection algorithm did not meet stringent roll requirements, but was shown to produce consistent coarse roll estimates while remaining independent of the mean scene σ and beam gain uncertainty. Other current algorithms can also be modified to use the hybrid data for potentially greater accuracy.

description: This paper analyzes a monopolist's behavior when consumers cannot observe the production standards. These types of products are usually known as credence goods. The steady-state level of quality with credence goods is found to be lower than that with experience goods, and perfect information goods. The finding that only perceived quality, which is effectively a filtered version of true quality, affects reputation indicates rewards for high quality production are lower in the credence good case. Further, an increase in the level of monitoring can increase the true level of product quality in the market for credence goods.

description: We describe a new library named picasso, which implements a unified framework of pathwise coordinate optimization for a variety of sparse learning problems (e.g., sparse linear regression, sparse logistic regression, sparse Poisson regression and scaled sparse linear regression) combined with efficient active set selection strategies. Besides, the library allows users to choose different sparsity-inducing regularizers, including the convex $\ell_1$, nonconvex MCP and SCAD regularizers. The library is coded in C++ and has user-friendly R and Python wrappers. Numerical experiments demonstrate that picasso can scale up to large problems efficiently.

description: The femtosecond optical pump-probe technique was used to study dynamics of photoexcited electrons and coherent optical phonons in transition metals Zn and Cd as a function of temperature and excitation level. The optical response in time domain is well fitted by linear combination of a damped harmonic oscillation because of excitation of coherent $E_{2g}$ phonon and a subpicosecond transient response due to electron-phonon thermalization. The electron-phonon thermalization time monotonically increases with temperature, consistent with the thermomodulation scenario, where at high temperatures the system can be well explained by the two-temperature model, while below $\approx$ 50 K the nonthermal electron model needs to be applied. As the lattice temperature increases, the damping of the coherent $E_{2g}$ phonon increases, while the amplitudes of both fast electronic response and the coherent $E_{2g}$ phonon decrease. The temperature dependence of the damping of the $E_{2g}$ phonon indicates that population decay of the coherent optical phonon due to anharmonic phonon-phonon coupling dominates the decay process. We present a model that accounts for the observed temperature dependence of the amplitude assuming the photoinduced absorption mechanism, where the signal amplitude is proportional to the photoinduced change in the quasiparticle density. The result that the amplitude of the $E_{2g}$ phonon follows the temperature dependence of the amplitude of the fast electronic transient indicates that under the resonant condition both electronic and phononic responses are proportional to the change in the dielectric function.

description: This study deals with modeling of production risk by means of a two-step procedure. In contrast to earlier studies of production risk, we do not immediately adopt restrictive functional forms for the risky production technology. We first test for the presence of production risk. If production risk is found to be present, the mean and risk functions are estimated separately. This allows the use of more flexible functional forms for both the mean and the risk functions than commonly found in the literature. An empirical application to Norwegian salmon farming, where restrictive specifications of the technology are rejected, demonstrates the validity of our approach. Presence of production risk many primary production sectors implies that this approach should be considered in productivity studies.

description: Fermion pair production at $e^-e^+$ linear collider experiments with polarized $e^-$ and $e^+$ beams is examined in the GUT inspired $SO(5)\times U(1)\times SU(3)$ gauge-Higgs unification. There arises large parity violation in the couplings of leptons and quarks to Kaluza-Klein (KK) excited neutral vector bosons $Z'$s, which leads to distinctive polarization dependence in cross sections, forward-backward asymmetries, left-right asymmetries, and left-right forward-backward asymmetries in various processes. Those effects are detectable even for the KK mass scale up to about 15 TeV at future $e^-e^+$ linear collider experiments with energies 250$\,$GeV to 1$\,$TeV.

description: The purpose of this survey is to explain some recent results about analogies between characteristic 0 and characteristic $p>0$ geometry, and to discuss an infinitesimal variant of motivic cohomology. More specifically, we review results showing that the big de Rham Witt complex of a field is a complex of 0-cycles (section 2), as well as results showing analogies between char. $p>0$ and char. 0 geometry. Some of those results determine local cohomology invariants of singular varieties (section 3) and others are concerned with congruences modulo $q$-powers for the number of rational points of varieties defined over $\F_q$ (section 1).

title: A Generic Object-Oriented Random Variate Model for Discrete Event Simulations Separating the Data Model from the Process Model
Creators: name: Frank, Palathingal
Publisher: name: Old Dominion University Libraries
Year: 1999

description: Data is the lifeline of any simulation model. The validity of the data is a primary determining factor on the accuracy of a simulation. Hence the data model is an important part of any simulation model. But this is, in most occasions, the most neglected part of any model. Most people view the model correctness in te1ms of the process model functionality rather than the data that is being used in the simulation. As simulation gets more accepted as a reliable problem-solving tool, it is increasingly important to pay careful attention to the accuracy of the simulation and that can only be achieved if the data model is accurate and functionally capable.

Classically, all complexity associated with the functionality of the model is integrated in the process model. This is true even when the complexity is inherently within the data. This causes excess process model complexity and an undesirable rigidity in the model capabilities. The properties of the data itself might be highly varied and could require some complex modeling rather than simple calls to random number generators. Thus, to serve these purposes and address various basic software enginee1ing requirements, it is essential to model data in a more generic and detailed fashion so as to separate the complexity of the data from the process. To support this new simulation paradigm, new constructs are required at the data model level.

This study deals with the development of a generic advanced random variate model that supports several of the data modeling issues. The primary aim of the study is to create a separate data model that handles all the complexity that is associated with the data in the simulation. It is designed to provide added functionality that has been classically placed in the process model but which could easily be moved to the data model. This simplifies the process model considerably so as to enable easy debugging and enhancement work on the model. The design also aims at providing maximum flexibility in te1ms of reusability in different scenarios. The model is object-oriented and is kept as generic as possible to enable reuse of the model in other object-oriented discrete event simulations.

The following study involves the in-depth analysis of the requirements of the random variate object model and the steps carried out towards the designing of the model. It also includes tests that were carried out for testing its functionality.

description: We study non-resonant and resonant Hopf bifurcation of a rotating wave in SO(3)-equivariant reaction-diffusion systems on a sphere. We obtained reduced differential equations on so(3), the characterization of modulated rotating waves obtained by Hopf bifurcation of a rotating wave, as well as results regarding the resonant case. Our main tools are the equivariant center manifold reduction and the theory of Lie groups and Lie algebras, especially for the group SO(3) of all rigid rotations on a sphere.

Kinetic theory of one-dimensional homogeneous long-range interacting systems with an arbitrary potential of interaction

description: Finite-$N$ effects unavoidably drive the long-term evolution of long-range interacting $N$-body systems. The Balescu-Lenard kinetic equation generically describes this process sourced by ${1/N}$ effects but this kinetic operator exactly vanishes by symmetry for one-dimensional homogeneous systems: such systems undergo a kinetic blocking and cannot relax as a whole at this order in ${1/N}$. It is therefore only through the much weaker ${1/N^{2}}$ effects, sourced by three-body correlations, that these systems can relax, leading to a much slower evolution. In the limit where collective effects can be neglected, but for an arbitrary pairwise interaction potential, we derive a closed and explicit kinetic equation describing this very long-term evolution. We show how this kinetic equation satisfies an $H$-theorem while conserving particle number and energy, ensuring the unavoidable relaxation of the system towards the Boltzmann equilibrium distribution. Provided that the interaction is long-range, we also show how this equation cannot suffer from further kinetic blocking, i.e., the ${1/N^{2}}$ dynamics is always effective. Finally, we illustrate how this equation quantitatively matches measurements from direct $N$-body simulations.
