description: Min-Nets are inspired by end-stopped cortical cells with units that output the minimum of two learned filters. We insert such Min-units into state-of-the-art deep networks, such as the popular ResNet and DenseNet, and show that the resulting Min-Nets perform better on the Cifar-10 benchmark. Moreover, we show that Min-Nets are more robust against JPEG compression artifacts. We argue that the minimum operation is the simplest way of implementing an AND operation on pairs of filters and that such AND operations introduce a bias that is appropriate given the statistics of natural images.

description: This works presents the theoretical analysis and experimental observations of bidirectional motion of a millimeter-scale bristle robot (milli-bristle-bot) with an on-board piezoelectric actuator. First, the theory of the motion, based on the dry-friction model, is developed and the frequency regions of the forward and backward motion, along with resonant frequencies of the system are predicted. Secondly, milli-bristle-bots with two different bristle tilt angles are fabricated, and their bidirectional motions are experimentally investigated. The dependency of the robot speed on the actuation frequency is studied,which reveals two distinct frequency regions for the forward and backward motions that well matches our theoretical predictions. Furthermore, the dependencies of the resonance frequency and robot speed on the bristle tilt angle are experimentally studied and tied to the theoretical model. This work marks the first demonstration of bidirectional motion at millimeter-scales, achieved for bristle-bots with a single on-board actuator.

description: Let Γbe a lattice in G=SL(n,R) and X=G/S a homogeneous space of G, where S is a closed subgroup of G which contains a real algebraic subgroup H such that G/H is compact. We establish uniform distribution of orbits of Γin X analogous to the classical equidistribution on torus. To obtain this result, we first prove an ergodic theorem along balls in the connected component of Borel subgroup of G.

description: This paper develops an efficiency-wage model where input prices affect the equilibrium rate of unemployment. We show that a simple framework based on only two prices (the real price of oil and the real rate of interest) is able to explain the main post-war movements in the rate of U.S. joblessness. The equations do well in forecasting unemployment many years out-of-sample, and provide evidence that the oil-price spike associated with Iraq’s invasion of Kuwait appears to be a component of the “mystery” recession which followed.

description: The INTEGRAL satellite extensively observed the black hole binary Cygnus X-1 from 2002 November to 2004 November during calibration, open time and core program (Galactic Plane Scan) observations. These data provide evidence for significant spectral variations over the period. In the framework of the accreting black hole phenomenology, the source was most of the time in the Hard State and occasionally switched to the so-called "Intermediate State". Using the results of the analysis performed on these data, we present and compare the spectral properties of the source over the whole energy range (5 keV - 1 MeV) covered by the high-energy instruments on board INTEGRAL, in both observed spectral states. Fe line and reflection component evolution occurs with spectral changes in the hard and soft components. The observed behaviour of Cygnus X-1 is consistent with the general picture of galactic black holes. Our results give clues to the physical changes that took place in the system (disc and corona) at almost constant luminosity during the spectral transitions and provide new measures of the spectral model parameters. In particular, during the Intermediate State of 2003 June, we observe in the Cygnus X-1 data a high-energy tail at several hundred keV in excess of the thermal Comptonization model which suggests the presence of an additional non-thermal component.

description: RooFit and RooStats, the toolkits for statistical modelling in ROOT, are used in most searches and measurements at the Large Hadron Collider as well as at $B$ factories. Larger datasets to be collected at e.g. the High-Luminosity LHC will enable measurements with higher precision, but will require faster data processing to keep fitting times stable. In this work, a simplification of RooFit's interfaces and a redesign of its internal dataflow is presented. Interfaces are being extended to look and feel more STL-like to be more accessible both from C++ and Python to improve interoperability and ease of use, while maintaining compatibility with old code. The redesign of the dataflow improves cache locality and data loading, and can be used to process batches of data with vectorised SIMD computations. This reduces the time for computing unbinned likelihoods by a factor four to 16. This will allow to fit larger datasets of the future in the same time or faster than today's fits.

Doping-induced non-Markovian interference causes excitonic linewidth broadening in monolayer WSe$_2$

Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: Strong Coulomb interactions in atomically thin semiconductors like monolayer WSe$_2$ induce not only tightly bound excitons, but also make their optical properties very sensible to doping. By utilizing a microscopic theory based on the excitonic Heisenberg equations of motion, we systematically determine the influence of doping on the excitonic linewidth, lineshift, and oscillator strength. We calculate trion resonances and demonstrate that the Coulomb coupling of excitons to the trionic continuum generates a non-Markovian interference, which, due to a time retardation, builds up a phase responsible for asymmetric exciton line shapes and increased excitonic linewidths. Our calculated doping dependence of exciton and trion linewidths, lineshifts, and oscillator strengths explains recent experiments. The gained insights provide the microscopic origin of the optical fingerprint of doped atomically thin semiconductors.

description: Based on the idea of variable stiffness mechanisms, a variety of such mechanisms is shown in this work. Specifically, 2-DOF parallel kinematic machines equipped with redundant actuators and non-linear springs in the actuated joints are presented and a comparative overview is drawn. Accordingly, a general stiffness formulation in task space of all mechanisms is given. Under fixed geometric parameters, optimization of task space stiffness is carried out on the designs comprising all kinematic solutions. Finally, a stiffness metric is introduced that allows a quantitative comparison of the given mechanism designs. This gives rise to design guidelines for engineers but also shows an interesting outline for future applications of variable stiffness mechanisms.

description: This study examines the effects of export price volatility in cattle markets using panel data from twelve countries between 1970 and 2013. Fixed-effects models with Driscoll and Kraay standard errors were estimated to control for cross-sectional dependence. Results indicate that price transmission depends on prices previously paid to farmers, variations in export prices and volatility of export prices, which reduces farmer prices in developed countries and it increases them in developing countries. In contrast, marketing margins are reduced by contemporaneous export price volatility and are increased by previous volatility. Exporters in developing countries take more time to transmit shocks in international prices, pay lower prices to farmers and absorb a bigger proportion of price fluctuations. These price transmission imperfections affect investments, technology adoption, production level and quality across the chain in developing countries, which negatively impact farmers, input and service providers, traders and other actors of the beef cattle chain.

description: This study analyzes the impact of anticipated investments to alter Brazilian port infrastructure on fertilizer flows and fertilizer transportation logistics costs using a linear programming model designed for the task. The most notable among these investments are directed toward accelerating port development in Brazil’s “Northern-Arc”, thereby increasing fertilizer supply to new markets opening throughout the country’s expanding agricultural frontier, particularly in northern Mato Grosso state, while increasing supply to existing markets. Results from model runs show that the anticipated port infrastructure investments should ensure nationwide fertilizer logistics savings of US$ 845 million over the 2017 through 2025 period. Although these estimated benefits are outstanding, the study indicates that further expansion of Brazil’s port system, particularly in the Northern-Arc, presents additional opportunities. Model projections were that in 2025, after all planned infrastructure improvements are operational, port terminals will be near full capacity, which should make planning for future projects a current priority.
Excitonic theory of doping-dependent optical response in atomically thin semiconductors

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: The interaction of optically excited excitons in atomically thin semiconductors with residual doping densities leads to many-body effects which are continuously tunable by external gate voltages. Here, we develop a fully microscopic theory to describe the doping-dependent manipulation of the excitonic properties in atomically thin transition metal dichalcogenides. In particular, we establish a diagonalization approach for the Schr\"odinger equation which characterizes the interaction of a virtual exciton with the Fermi sea of dopants. Solving this many-body Schr\"odinger equation provides access to trions as well as a continuum of scattering states. The dynamics of coupled excitons, trions, and scattering continua is subsequently described by Heisenberg equations of motion including mean-field contributions and correlation effects due to the interaction of excitons with trions and scattering continuum states. Our calculations for optical excitation close to the band edge reveal the influence of doping on the exciton resonances in combination with the simultaneous identification of not only ground-, but also excited-, state trion resonances.

Measurement of the cross section for $\text{t}\bar{\text{t}}$ production with additional jets and b jets in pp collisions at $\sqrt{s} =$ 13 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: Measurements of the cross section for the production of top quark pairs in association with a pair of jets from bottom quarks ($σ_\mathrm{t\bar{t}b\bar{b}}$) and in association with a pair of jets from quarks of any flavor or gluons ($σ_\mathrm{t\bar{t}jj}$) and their ratio are presented. The data were collected in proton-proton collisions at a center-of-mass energy of 13 TeV by the CMS experiment at the LHC in 2016 and correspond to an integrated luminosity of 35.9 fb$^{-1}$. The measurements are performed in a fiducial phase space and extrapolated to the full phase space, separately in the dilepton and lepton+jets channels, where lepton corresponds to either an electron or a muon. The results for the dilepton and lepton+jets channels, respectively, are $σ_\mathrm{t\bar{t}jj}$ = 2.36 $\pm$ 0.02 (stat) $\pm$ 0.20 (syst) pb and 31.0 $\pm$ 0.2 (stat) $\pm$ 2.9 (syst) pb, and for the cross section ratio 0.017 $\pm$ 0.001 (stat) $\pm$ 0.001 (syst) and 0.020 $\pm$ 0.001 (stat) $\pm$ 0.001 (syst). The values of $σ_\mathrm{t\bar{t}b\bar{b}}$ are determined from the product of the $σ_\mathrm{t\bar{t}jj}$ and the cross section ratio, obtaining, respectively, 0.040 $\pm$ 0.002 (stat) $\pm$ 0.005 (syst) pb and 0.62 $\pm$ 0.03 (stat) $\pm$ 0.07 (syst) pb. These measurements are the most precise to date and are consistent, within the uncertainties, with the standard model expectations obtained using a matrix element calculation at next-to-leading order in quantum chromodynamics matched to a parton shower.

description: This case study provides a thorough description of the U.S. orange juice industry, and focuses on Florida’s Natural, a cooperative of citrus growers and owner of the Florida’s Natural® brand. Florida’s Natural® competes mainly with Tropicana, owned by PepsiCo, and with Minute Maid and Simply Orange, brands of The Coca-Cola Company. The objective of the case is to evaluate the orange juice industry, assess the position of Florida’s Natural within the industry, and propose business actions for the cooperative. By the end of 2016, the orange juice industry was in the midst of a severe crisis, threatened by decreasing supply and changing consumption preferences. Total orange production in the State of Florida during the 2015-16 season was the smallest crop since the 1960s due mainly to a disease known as citrus greening. Marketers were also facing consumers’ concerns regarding high levels of calories and sugar in some juice categories. Furthermore, on May 2016, the Food and Drug Administration mandated a change in the nutrition facts label on packaged food, becoming effective in the summer of 2018, which may impact marketers in the sector.

description: Declining pollinator insect populations is an important global concern due to potential negative environmental and economic consequences. However, research on consumer perceptions of pollinator friendly traits is limited. Understanding consumer perceptions is important because they impact behavior and product selection. In turn, this affects the effectiveness of relevant policies and pollinator insects’ access to beneficial plants. This manuscript quantifies consumers’ perceptions of plant traits that aid pollinators. U.S. consumers (n=1,243) were surveyed to identify their perceptions of pollinator friendly traits. Binary logit models and marginal effects were estimated using 22 plant traits and consumers’ purchasing interest, existing knowledge, and demographic variables. Results imply consumers interested in purchasing pollinator friendly plants selected positive traits regardless of accuracy. Furthermore, consumers selected traits that aligned with their knowledge. Older participants had more accurate perceptions of pollinator friendly traits. Results highlight the challenges facing regulatory efforts geared towards promoting pollinator friendly products/practices.

description: We present the results of a survey for Ly$α$ emitters at $z\approx 5.7$ based on optical narrow-band ($λ_{\rm c} = 8150$ Å~ and $Δλ= 120$ Å), and broad-band ($B$, $R_{\rm C}$, $I_{\rm C}$, and $z^\prime$) observations of the field surrounding the high redshift quasar, SDSSp J104433.04$-$012522.2, on the 8.2 m Subaru Telescope with the Subaru Prime Focus Camera, Suprime-Cam. This survey covers a sky area of $\approx 720$ arcmin$^2$ and a co-moving volume of $\simeq 2 \times 10^5 ~ h_{0.7}^{-3}$ Mpc$^3$. We have found 20 candidates of Ly$α$ emitters at $z \approx$ 5.7 with $Δz \approx 0.1$. Two of them have been confirmed star-forming galaxies at $z=5.655$ and $z=5.687$ from our follow-up optical spectroscopy. We discuss star-formation properties of the 20 objects from a statistical point of view. Our survey leads to a new estimate of the star formation rate density at $z \approx 5.7$, $\sim 1.2 \times 10^{-3} h_{0.7} M_\odot$ yr$^{-1}$ Mpc$^{-3}$.

description: The current study investigated the effects of feedback frequency and goal reward on subject motivation. Klein's (1989) control theory model of work motivation was used to conceptualize the method and hypothesis. Subjects performed a simple computer addition task. When we examined subjects who displayed medium to high mathematical ability, significant effects were discovered. Higher goal reward led to higher motivation. In addition, subjects with a low goal reward and high amounts of feedback displayed lower motivation than subjects with a high goal reward and high amounts of feedback and subjects with a high goal reward and low amounts of feedback. The usefulness of control theory is discussed.

Cost, Cost-Effectiveness, and Cost-Benefit of Attachment Biobehavioral Catch-up (ABC)
Creators: name: French, Alexis N.
Publisher: name: American University
Year: 2023

description: Attachment Biobehavioral Catch-up (ABC) is a home visiting program that teaches caregivers how to provide sensitive and nurturing care to their children (Dozier, 2010; Dozier & Bernard, 2019). Although the effectiveness of ABC has been evaluated previously, the intervention has yet to undergo an evaluation of its costs and cost-effectiveness. We assessed and compared costs of delivering ABC in research and real-world settings from four perspectives (client, provider, administrator, and overall). The current study found that ABC was significantly more costly from all four perspectives when delivered in a real-world setting (overall median: $2,502) than a controlled setting (overall median: $1,661). When comparing costs of ABC to an active control intervention from a randomized controlled trial, ABC was significantly more expensive than the control intervention from only the administrative perspective, but not from the client, provider, and overall perspectives. With regard to effectiveness, results indicated that (a) caregivers receiving ABC significantly increased their sensitivity and nonintrusiveness from pre- to posttreatment, (b) children whose caregivers received ABC had significantly higher rates of organized attachment, and (c) children whose caregivers received ABC had marginally higher cortisol levels at wake-up and significantly steeper cortisol slope from wake-up to bedtime on Days 1 and 2 than children with caregivers who received Developmental Education for Families (DEF). No significant differences were found between ABC and DEF for children’s attachment security. Individual cost-effectiveness ratios examined costs of producing a one-unit change in ABC parenting skills as well as children’s cortisol slope. We also discussed a framework for conducting a cost-benefit analysis of ABC in the future. Results from the current study support the expansion of ABC, as it enhances stakeholders’ understanding of the value of resources essential for delivering ABC.

Electron inertia is shown to have a negligible effect on the evolution of the system whenever the collisionless skin depth is less than the resistive scale length. Non-potential magnetic field energy in this resistive MHD limit initially reaches equipartition with flow energy, in accordance with ideal MHD, and is then dissipated extremely rapidly, on an Alfvenic timescale that is essentially independent of Lundquist number. In agreement with resistive MHD results obtained by previous authors, the magnetic field energy and kinetic energy are then observed to decay on a longer timescale and exhibit oscillatory behavior, reflecting the existence of discrete normal modes with finite real frequency. When the collisionless skin depth exceeds the resistive scale length, the system again evolves initially according to ideal MHD. At the end of this ideal phase, the field energy decays typically on an Alfvenic timescale, while the kinetic energy (which is equally partitioned between ions and electrons in this case) is dissipated on the electron collision timescale. The oscillatory decay in the energy observed in the resistive case is absent, but short wavelength structures appear in the field and velocity profiles, suggesting the possibility of particle acceleration in oppositely-directed current channels. The model provides a possible framework for interpreting observations of energy release and particle acceleration on timescales down to less than a second in the impulsive phase of solar flares.

description: The goal of this study was to survey farmers and agribusiness owners about their perceptions of cyber security, and how age, gender, and education might affect those perceptions. Using the Health Belief Model as a framework, the survey measured the constructs of perceived susceptibility, severity, benefits, barriers, self-efficacy and cues to action. In addition to the framework, levels of previous cyber-crime victimization and technology implementation were measured. The results of this survey demonstrated that perceived susceptibility to cyber-attacks and the perceived benefits of protective technology are related to an individual’s choice to implement cyber security technology. Over half of the respondents had been victims of a computer security incident, demonstrating that even individuals working in agriculture can be impacted by computer crime incidents. This project deepens the understanding of how individuals react to known threats, and what motivates them to adopt protection technologies.

description: Several static and dynamic properties of liquid silicon near melting have been determined from an orbital free {\em ab-initio} molecular dynamics simulation. The calculated static structure is in good agreement with the available X-ray and neutron diffraction data. The dynamical structure shows collective density excitations with an associated dispersion relation which closely follows recent experimental data. It is found that liquid silicon can not sustain the propagation of shear waves which can be related to the power spectrum of the velocity autocorrelation function. Accurate estimates have also been obtained for several transport coefficients. The overall picture is that the dynamic properties have many characteristics of the simple liquid metals although some conspicuous differences have been found.

description: \ce{MoS_2} is a two dimensional material with a band gap depending on the number of layers and tunable by an external electric field. The experimentally observed intralayer band-to-band tunneling and interlayer band-to-band tunneling in this material present an opportunity for new electronic applications in tunnel field effect transistors. However, such a widely accepted concept has never been supported up by theoretical investigations based on first principles. In this work, using density functional theory, in conjunction with non-equilibrilibrium Green's function techniques and our electric field gating method, enabled by a large-scale computational approach, we study the relation between band alignment and transmission in planar and side-stack \ce{MoS_2} $p$-$i$-$n$ junction configurations. We demonstrate the presence of negative differential resistance for both in-plane and interlayer current, a staple characteristic of tunnel diode junctions, and analyze the physical origin of such an effect. Electrostatic potentials, the van der Waals barrier, and complex band analysis are also examined for a thorough understanding of Esaki Diodes.

description: The massive two-dimensional Nambu--Jona-Lasinio model with isospin (isoNJL) is reconsidered in the large $N_c$ limit. We continue the exploration of its phase diagram by constructing missing first-order phase boundaries. At zero temperature, a phase boundary in the plane of baryon and isospin chemical potentials separates the vacuum from a crystal phase. We derive it from the baryon spectrum of the isoNJL model which, in turn, is obtained via a numerical Hartree-Fock (HF) calculation. At finite temperature, a first-order phase boundary sheet is found using a thermal HF calculation. It interpolates smoothly between the zero temperature phase boundary and the perturbative sheet. The calculations remain tractable owing to the assumption that the charged pion condensate vanishes. In that case, most of the calculations can be done with methods developed in the past for solving the massive one-flavor NJL model.

description: The nature of the pseudogap phase of cuprates remains a major puzzle. One of its new signatures is a large negative thermal Hall conductivity $κ_{\rm xy}$, which appears for dopings $p$ below the pseudogap critical doping $p^*$, but whose origin is as yet unknown. Because this large $κ_{\rm xy}$ is observed even in the undoped Mott insulator La$_2$CuO$_4$, it cannot come from charge carriers, these being localized at $p = 0$. Here we show that the thermal Hall conductivity of La$_2$CuO$_4$ is roughly isotropic, being nearly the same for heat transport parallel and normal to the CuO$_2$ planes, i.e. $κ_{\rm zy}(T) \approx κ_{\rm xy} (T)$. This shows that the Hall response must come from phonons, these being the only heat carriers able to move as easily normal and parallel to the planes . At $p > p^*$, in both La$_{\rm 1.6-x}$Nd$_{\rm 0.4}$Sr$_x$CuO$_4$ and La$_{\rm 1.8-x}$Eu$_{\rm 0.2}$Sr$_x$CuO$_4$ with $p = 0.24$, we observe no c-axis Hall signal, i.e. $κ_{\rm zy}(T) = 0$, showing that phonons have zero Hall response outside the pseudogap phase. The phonon Hall response appears immediately below $p^* = 0.23$, as confirmed by the large $κ_{\rm zy}(T)$ signal we find in La$_{1.6-x}$Nd$_{\rm 0.4}$Sr$_x$CuO$_4$ with $p = 0.21$. The microscopic mechanism by which phonons become chiral in cuprates remains to be identified. This mechanism must be intrinsic - from a coupling of phonons to their electronic environment - rather than extrinsic, from structural defects or impurities, as these are the same on both sides of $p^*$. This intrinsic phonon Hall effect provides a new window on quantum materials and it may explain the thermal Hall signal observed in other topologically nontrivial insulators.

description: We present a scenario in which Yukawa-like R-parity violating (RPV) couplings are naturally suppressed. In our framework, RPV is assumed to originate from the SUSY breaking mechanism and then transmitted into the SUSY Lagrangian only through soft SUSY breaking operators in the scalar potential. The RPV Yukawa-like operators of the superpotential, conventionally parametrized by the couplings λ, λ' and λ'', are then generated through loops containing the SUSY scalars, the gauginos and the soft RPV interactions and are, therefore, manifest as effective operators with a typical strength of order 10^{-3}.

description: Bayesian inference is a powerful paradigm for quantum state tomography, treating uncertainty in meaningful and informative ways. Yet the numerical challenges associated with sampling from complex probability distributions hampers Bayesian tomography in practical settings. In this Article, we introduce an improved, self-contained approach for Bayesian quantum state estimation. Leveraging advances in machine learning and statistics, our formulation relies on highly efficient preconditioned Crank--Nicolson sampling and a pseudo-likelihood. We theoretically analyze the computational cost, and provide explicit examples of inference for both actual and simulated datasets, illustrating improved performance with respect to existing approaches.

description: Attachment Biobehavioral Catch-up (ABC) is a home visiting program that teaches caregivers how to provide sensitive and nurturing care to their children (Dozier, 2010; Dozier & Bernard, 2019). Although the effectiveness of ABC has been evaluated previously, the intervention has yet to undergo an evaluation of its costs and cost-effectiveness. We assessed and compared costs of delivering ABC in research and real-world settings from four perspectives (client, provider, administrator, and overall). The current study found that ABC was significantly more costly from all four perspectives when delivered in a real-world setting (overall median: $2,502) than a controlled setting (overall median: $1,661). When comparing costs of ABC to an active control intervention from a randomized controlled trial, ABC was significantly more expensive than the control intervention from only the administrative perspective, but not from the client, provider, and overall perspectives. With regard to effectiveness, results indicated that (a) caregivers receiving ABC significantly increased their sensitivity and nonintrusiveness from pre- to posttreatment, (b) children whose caregivers received ABC had significantly higher rates of organized attachment, and (c) children whose caregivers received ABC had marginally higher cortisol levels at wake-up and significantly steeper cortisol slope from wake-up to bedtime on Days 1 and 2 than children with caregivers who received Developmental Education for Families (DEF). No significant differences were found between ABC and DEF for children’s attachment security. Individual cost-effectiveness ratios examined costs of producing a one-unit change in ABC parenting skills as well as children’s cortisol slope. We also discussed a framework for conducting a cost-benefit analysis of ABC in the future. Results from the current study support the expansion of ABC, as it enhances stakeholders’ understanding of the value of resources essential for delivering ABC.

description: Global agricultural markets reflect the increasing complexity of modern consumer demand for food safety and quality. This demand has triggered changes throughout the food industry, and led to greater opportunities for product differentiation and the potential to add value to raw commodities. Greater differentiation and value adding over time has in turn dramatically changed the price spread or marketing bill between the farm value of products and the retail value. Thus a significantly greater percentage of the final price paid by consumers is now garnered down chain rather than up chain over the last 20 years. This apparent shifting of value creation or addition, as measured by the marketing margin, has invigorated empirical questions as to where, and how much value, is created along the agri-food value chain. First we define value creation/adding, and then we estimate the economic value added for 454 firms. We validate our findings by creating and employing three additional value creation measures – the modified economic value added, the creation or destruction of value, and the persistence of value creation. Finally we estimate value creation at each node of the value chain, measure the relative differences among firms and nodes, and estimate a model measuring the drivers of value adding.
