 Description. Male holotype. Length approximately 3.0 mm, width 2.2 mm; body short, wide, elytra much wider than pronotal base, widest at anterior 1/3 of elytra. Elytral surface entirely shiny, lacking microsculpture. Color of head and pronotum unknown, elytron pale red except black macula extended from base to apex medially, macula narrow on basal margin inside humeral callus, narrowly extended along sutural margin to just posterior to middle then widened to occupy remainder of elytron (Fig. 82); venter and legs yellow except prosternum slightly darker than remainder of venter. Elytral punctures separated by a diameter or less; prosternal punctures large, separated by less than a diameter; metasternal depression impunctate, lateral punctures large, separated by less than a diameter; punctures on abdominal ventrites 1, 2 large, separated by less than 3 times a diameter, inside of postcoxal lines lacking punctures, punctures on remaining ventrites small, separated by about a diameter. Epipleuron flat, wide in basal ½. Prosternum as in Fig.84. Postcoxal line on ventrite 1 short, narrow, evenly rounded, extended slightly more than ½ distance to apical margin of ventrite (Fig. 83). Apex of ventrite 5 evenly rounded. Genitalia with basal lobe as long as paramere, wide in basal ½, then narrowed in apical ½ to bluntly rounded apex; paramere widest medially, narrowed to thickened, abruptly bent apex, dorsal margin with trace of blunt serrations medially (Fig. 85–86); sipho robust, wide throughout, apex complex, sinuate medially (Fig. 87).
 Female. Unknown.
 Variation. Unknown.
 Type material. Holotype male; Ivon, Beni, Boliv (BOLIVIA) Feb, WMMann, Mulford Biol. Expl. 1921– 1922.m USNM.
 Remarks. The holotype is missing a head and pronotum but the remainder is intact including abdomen with male genitalia. Because of this and the unique elytral color pattern the species is described. It does not resemble any known species of Neaporia in color pattern, but male genitalia are similar to those of several other species.

description: Acoustic signal has been used to sense important contextual information of targets such as location and movement. This paper explores its potential for measuring the geometric information of moving targets, i.e., shape and size. We propose SONDAR, a novel shape and size measurement system using Inverse Synthetic Aperture Radar (ISAR) imaging on commodity devices. We first design a Doppler-free echo alignment method to accurately align target reflections even if there exists a severe Doppler effect. Then we down-convert the received signals reflected from multiple scatter points on the target and construct a modulated downchirp signal to generate the image. We further develop a lightweight approach to extract the geometric information from a 2-D frequency image. We implement and evaluate a proof-of-concept system on both a Bela platform and a smartphone. Extensive experiments show that we can correctly estimate the target shape and achieve a millimeterlevel size measurement accuracy. Our system can achieve high accuracies even when the target moves along a deviated trajectory, at a relatively high speed, and under obstruction.

description: The standard model for the operation of the s-process in asymptotic giant branch (AGB) stars predicts that low-metallicity ([Fe/H] <= -1) AGB stars should exhibit large overabundances of Pb and Bi as compared to other s-elements. Eight CH stars (with [Fe/H] ranging from -1.5 to -2.5) are studied in the present paper using high-resolution spectra (R = lambda/Delta lambda = 135 000), and five of them appear to be enriched in lead (with [Pb/Ce] ~ 0.7). Abundances of heavy elements in these `lead stars' (defined as stars enriched in s-elements and with [Pb/hs] >= 1, hs being any of Ba, La or Ce) are consistent with the predictions for the s-process operating in low-metallicity AGB stars as a consequence of the `partial mixing' of protons below the convective hydrogen envelope. Two among the studied stars (HD 189711 and V Ari) add to a growing number of low-metallicity stars which do not conform to these predictions, however. Variations on the canonical proton-mixing scenario for the operation of the s-process in low-metallicity stars, that could account for these discrepant stars, are briefly discussed.

description: We study the Intra-Halo Stellar Component (IHSC) of Milky Way-mass systems up to galaxy clusters in the Horizon-AGN cosmological hydrodynamical simulation. We identify the IHSC using an improved phase-space galaxy finder algorithm which provides an adaptive, physically motivated and shape-independent definition of this stellar component, that can be applied to halos of arbitrary masses. We explore the IHSC mass fraction-total halo's stellar mass, $f_{M*,IHSC}-M*$, relation and the physical drivers of its scatter. We find that on average the $f_{M*,IHSC}$ increases with $M_{*,tot}$, with the scatter decreasing strongly with mass from 2 dex at $M_{*,tot}\sim10^{11}M_\odot$ to 0.3 dex at group masses. At high masses, $M_{*,tot}>10^{11.5}M_\odot$, $f_{M*,IHSC}$ increases with the number of substructures, and with the mass ratio between the central galaxy and largest satellite, at fixed $M_{*,tot}$. From mid-size groups and systems below $M_{*,tot}<10^{12}M_\odot$, we find that the central galaxy's stellar rotation-to-dispersion velocity ratio, V/σ, displays the strongest (anti)-correlation with $f_{M*,IHSC}$ at fixed $M_{*,tot}$ of all the galaxy and halo properties explored, transitioning from $f_{M*,IHSC}$<0.1% for high V/σ, to $f_{M*,IHSC}\sim5$% for low V/σ galaxies. By studying the $f_{M*,IHSC}$ temporal evolution, we find that, in the former, mergers not always take place, but if they did, they happened early (z>1), while the high $f_{M*,IHSC}$ population displays a much more active merger history. In the case of massive groups and galaxy clusters, $M_{*,tot}>10^{12}M_\odot$, a fraction $f_{M*,IHSC}\sim$10-20% is reached at $z\sim1$ and then they evolve across lines of constant $f_{M*,IHSC}$ modulo some small perturbations. Because of the limited simulation's volume, the latter is only tentative and requires a larger sample of simulated galaxy clusters to confirm.

description: In this paper, we introduce a novel mechanism that uses machine learning techniques to detect water leaks in pipes. The proposed simple and low-cost mechanism is designed that can be easily installed on building pipes with various sizes. The system works based on gathering and amplifying water flow signals using a mechanical sound amplifier. Then sounds are recorded and converted to digital signals in order to be analyzed. After feature extraction and selection, deep neural networks are used to discriminate between with and without leak pipes. The experimental results show that this device can detect at least 100 milliliters per minute (mL/min) of water flow in a pipe so that it can be used as a core of a water leakage detection system.
The Higgs Sector in a $U(1)^\prime$ Extension of the MSSM

description: We consider the Higgs sector in an extension of the MSSM with extra SM singlets, involving an extra $U(1)^\prime$ gauge symmetry, in which the domain-wall problem is avoided and the effective $μ$ parameter is decoupled from the new gauge boson $Z^\prime$ mass. The model involves a rich Higgs structure very different from that of the MSSM. In particular, there are large mixings between Higgs doublets and the SM singlets, significantly affecting the Higgs spectrum, production cross sections, decay modes, existing exclusion limits, and allowed parameter range. Scalars considerably lighter than the LEP2 bound (114 GeV) are allowed, and the range $\tan β\sim 1$ is both allowed and theoretically favored. Phenomenologically, we concentrate our study on the lighter (least model-dependent, yet characteristic) Higgs particles with significant SU(2)-doublet components to their wave functions, for the case of no explicit CP violation in the Higgs sector. We consider their spectra, including the dominant radiative corrections to their masses from the top/stop loop. We computed their production cross sections and reexamine the existing exclusion limits at LEP2. We outline the searching strategy for some representative scenarios at a future linear collider. We emphasize that gaugino, Higgsino, and singlino decay modes are indicative of extended models and have been given little attention. We present a comprehensive list of model scenarios in the Appendices.

description: Disinformation poses a serious threat to society. Researchers have shown that many people spread disinformation, especially in relation to the COVID-19 pandemic, on social media platforms like Instagram. However, performing disinformation analysis is difficult if those users have been banned. Previous research has shown that web archives are useful for performing disinformation analysis on pages that are no longer live, but this approach is limited by web page capture availability. To better understand how disinformation is spreading on Instagram, we examine how disinformation actors are utilizing hashtags and account mentions to boost engagement by extracting engagement metrics from archived Instagram account pages. We use the data gathered from these archived webpages, or mementos, to perform network analysis showing how engagement connects users. We then perform clustering based on hashtag frequency to examine how people searching for reputable content are being exposed to disinformation by identifying groupings that contain both health authority accounts and anti-vax accounts. Our findings indicate that roughly one-fifth of intra-group hashtags are also distributed inter-group. Limited memento availability remains an obstacle to comparing reputable accounts to disinformation accounts, but a higher percentage of Instagram account page mementos from the Archive.today web archive are able to be scraped than those from the Internet Archive’s Wayback Machine.
Long-Run Diversion Effects of Changes in Truck Size and Weight (TS&W) Restrictions: An Update of the 1980 Friedlaender Spady Analysis
Creators: name: McCullough, Gerard J.

description: The purpose of this analysis is to estimate the effect that revised truck size and weight (TS&W) restrictions would have on competitive rail-truck markets in the United States. The analysis is based on a classic study of the intercity freight markets that Ann Friedlaender and Richard Spady (FS) published in the Review of Economics and Statistics in 1980.1 The FS study provided a macro-level perspective on the freight markets by focusing on transportation decisions in key industrial sectors—food, wood products, paper, chemicals, automobiles, and so on. The FS analysis and the current update of that analysis complement the short-run estimates of rail-truck competition levels that are commonly obtained using logit-based models of freight demand. For example, a logit model was a central component of the Intermodal Transportation and Inventory Cost (ITIC) Model used by the U.S. Department of Transportation (DOT) in the 2000 Comprehensive Truck Size and Weight Study. Logit models present a relatively fixed assessment of freight demand that is shipment focused and market specific with respect to both commodities and geographic pairs. The FS analysis is based on a more generalized economic framework in which shippers have the flexibility to choose a range of productive inputs that includes truck and rail freight transportation along with labor, materials and capital. The FS framework thus provides a broader and longer term perspective on the potential effect that changes in TS&W regulations would have on the freight markets. The logit estimates can be viewed as identifying the shorter term, lower bounds of the cross-price elasticities between truck and rail while the FS estimates identify long term, upper bounds. The diversion effects analyzed in the current study are based on a hypothetical ten percent decrease in truck prices. This assumption is based in turn on the TS&W cost effects projected by the DOT in its 2000 Comprehensive Truck Size and Weight Study. Though the projected reduction in truck costs is fairly conservative, the losses of rail market share are significant—on the order of 15 to 20 percent in several key competitive rail-truck markets. The impacts on highway users and on railroad shippers who remain on the rail network are also significant. The projected increase in heavy truck traffic is 3.05 billion vehicle miles per year and the projected loss in base year railroad net income is $750 million per year. Total railroad net income in the base year was just $3.2 billion.

description: Directional transport is obtained in various multimode systems by driving multiple, nonreciprocally-interfering interactions between individual bosonic modes. However, systems sustaining the required number of modes become physically complex. In our microwave-optomechanical experiment, we show how to configure nonreciprocal transport between frequency components of a single superconducting cavity coupled to two drumhead oscillators. The frequency components are promoted to Floquet modes and generate the missing dimension to realize an isolator and a directional amplifier. A second cavity left free by this arrangement is used to cool the mechanical oscillators and bring the transduction noise close to the quantum limit. We furthermore uncover a new type of instability specific to nonreciprocal coupling. Our approach is generic and can greatly simplify quantum signal processing and the design of topological lattices from low-dimensional systems.

description: The Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy (VERITAS) mission, selected by the NASA Discovery program in 2021, addresses crucial scientific questions about Venus’s evolution, structure, and past and ongoing geological processes. The high-resolution mapping of the gravity field of the planet will give an essential contribution to meet the science objectives of the mission and to further our understanding of Venus. The VERITAS gravity science experiment will enable a gravity map of the planet with substantially higher and more uniform spatial resolution with respect to Magellan. This is achieved thanks to the near-polar, near-circular, lowaltitude orbit (~220 km), and the state-of-the-art quality of Doppler tracking data, collected from two separate and coherent radio links at X and Ka band. Our numerical simulations show that the VERITAS gravity science experiment can robustly fulfill the scientific requirements, achieving a gravity field spatial resolution ranging from 85 to 120 km. Across 90% of the planet, a spatial resolution better than 106 km is expected. Additionally, VERITAS can retrieve crucial parameters required to derive the tidal response and rotational state of Venus, thereby improving our understanding of the planet’s interior structure.

description: The effect of deformation on the two-neutrino double decay (2nbb-decay) for ground state transition 76Ge -> 76Se is studied in the framework of the deformed QRPA with separable Gamow-Teller residual interaction. A new suppression mechanism of the 2nbb-decay matrix element based on the difference in deformations of the initial and final nuclei is included. An advantage of this suppression mechanism in comparison with that associated with ground state correlations is that it allows a simultaneous description of the single beta and the 2nbb-decay. By performing a detail calculation of the 2nbb-decay of 76Ge, it is found that the states of intermediate nucleus lying in the region of the Gamow-Teller resonance contribute significantly to the matrix element of this process.

description: Though the neutrino-driven convection model for the core-collapse explosion mechanism has received strong support in recent years, there are still many uncertainties in the explosion parameters -- such as explosion energy, remnant mass, and end-of-life stellar abundances as initial conditions. Using a broad set of spherically symmetric core-collapse simulations we examine the effects of these key parameters on explosive nucleosynthesis and final explosion yields. Post-bounce temperature and density evolution of ZAMS 15, 20, and 25 solar mass progenitors are post-processed through the Nucleosynthesis Grid (NuGrid) nuclear network to obtain detailed explosive yields. In particular, this study focuses on radio-isotopes that are of particular interest to the next generation of gamma-ray astronomical observations; 43K, 47Ca, 44Sc, 47Sc, 48V, 48Cr, 51Cr, 52Mn, 59Fe, 56Co, 57Co, 57Ni. These nuclides may be key in advancing our understanding of the inner workings of core-collapse supernovae by probing the parameters of the explosion engine. We find that the isotopes that are strong indicators of explosion energy are 43K, 47Ca, 44Sc, 47Sc, and 59Fe, those that are dependent on the progenitor structure are 48V, 51Cr, and 57Co, and those that probe neither are 48Cr, 52Mn, 57Ni, and 56Co. We discuss prospects of observing these radionuclides in supernova remnants.

description: The objective of this paper was to analyze the determinants of smallholder milk production expansion in four Brazilian regions: Zona da Mata (MG), Rio de Janeiro, Tocantins, and Rondônia. A three years multi-period linear programming model was formulated to attain the objective purposed. The results show that smallholders can improve substantially their income with the adoption of low cost technologies, such as improvement in feeding and reproduction practices. The role of the public sector is important in this process of adoption of new technologies, especially providing accessible veterinary and extension services, and soft loans.

Privilegia-se a perspectiva do investimento e do processo de fidelização dos cooperados. Tomando como fonte básica de dados os documentos internos da cooperativa COLASO, foram levantados os investimentos realizados no período de 1970 a 2004 para a industrialização do leite e seus derivados. Os resultados obtidos indicam que, no que se refere ao denominado problema do horizonte, não se sustenta a afirmação de que as cooperativas tendem a rejeitar estratégias que impliquem investimentos por longos períodos para viabilizar projetos de diferenciação de produtos. Também não se sustenta a idéia de que o desvio da produção pode promover a perda do valor dos investimentos realizados.

description: The soil bacterium Myxococcus xanthus lives in densely packed groups that form dynamic three-dimensional patterns in response to environmental changes, such as droplet-like fruiting bodies during starvation. The development of these multicellular structures begins with the sequential formation of cell layers in a process that is poorly understood. Using confocal three-dimensional imaging, we find that motile rod-shaped M. xanthus cells are densely packed and aligned in each layer, forming an active nematic liquid crystal. Cell alignment is nearly perfect throughout the population except at point defects that carry half-integer topological charge. We observe that new cell layers preferentially form at the position of +1/2 defects, whereas holes preferentially open at -1/2 defects. To explain these findings, we model the bacterial colony as an extensile active nematic fluid with anisotropic friction. In agreement with our experimental measurements, this model predicts an influx of cells toward +1/2 defects, and an outflux of cells from -1/2 defects. Our results suggest that cell motility and mechanical cell-cell interactions are sufficient to promote the formation of cell layers at topological defects, thereby seeding fruiting bodies in colonies of M. xanthus.

description: A next-generation medium-energy gamma-ray telescope targeting the MeV range would address open questions in astrophysics regarding how extreme conditions accelerate cosmic-ray particles, produce relativistic jet outflows, and more. One concept, AMEGO-X, relies upon the mission-enabling CMOS Monolithic Active Pixel Sensor silicon chip AstroPix. AstroPix is designed for space-based use, featuring low noise, low power consumption, and high scalability. Desired performance of the device include an energy resolution of 5 keV (or 10% FWHM) at 122 keV and a dynamic range per-pixel of 25-700 keV, enabled by the addition of a high-voltage bias to each pixel which supports a depletion depth of 500 um. This work reports on the status of the AstroPix development process with emphasis on the current version under test, version three (v3), and highlights of version two (v2). Version 3 achieves energy resolution of 10.4 +\- 3.2 % at 59.5 keV and 94 +\- 6 um depletion in a low-resistivity test silicon substrate.

description: In order to provide more effective treatment strategies for the rapid healing of diabetic wounds, novel therapeutic approaches need to be developed. The therapeutic potential of peroxisome proliferator-activated receptor-γ (PPAR-γ) agonist pioglitazone hydrochloride (PHR) in two different release kinetic scenarios, burst release and sustained release, were investigated and compared with in vitro and in vivo tests as potential wound healing dressings. PHR-loaded fibrous mats were successfully fabricated using polyvinyl pyrrolidone and polycaprolactone by scalable pressurized gyration. The results indicated that PHR-loaded fibrous mats expedited diabetic wound healing in type-1 diabetic rats and did not show any cytotoxic effect on NIH/3T3 (mouse embryo fibroblast) cells, albeit with different release kinetics and efficacies. The wound healing effects of fibrous mats are presented with histological and biochemical evaluations. PHR-loaded fibrous mats improved neutrophil infiltration, oedema, and inflammation and increased epidermal regeneration and fibroblast proliferation but the formation of hair follicles and completely improved oedema were observed only in the sustained release form. Thus, topical administration of PPAR-γ agonist in sustained release form has high potential for the treatment of diabetic wounds in inflammatory and proliferative phases of healing with high bioavailability and fewer systemic side effects.

description: Structural and optical properties of MBE-grown GaAs(001) surface have been studied by reflection high-energy electron diffraction and single-wavelength ellipsometry under dynamic conditions of ramp heating after desorption of passivating As-cap-layer with and without As4 beam applied to the surface. For a number metastable reconstruction transitions a clear correlation is stablished between diffraction and optical data. Boundary lines for transitional superstructures are determined as a function of As flux and corresponding activation energies are estimated. For the first time it is shown ellipsometrically that optical response of the surface is drastically different for transitions of the order->order and order->disorder type.

description: Variability studies offer a compelling glimpse into black hole dynamics, and NICER's (Neutron Star Interior Composition Explorer) remarkable temporal resolution propels us even further. NICER observations of an Active Galactic Nucleus (AGN), NGC 4051, have charted the geometry of the emission region of the central supermassive black hole. Our investigation of X-ray variability in NGC 4051 has detected extreme variations spanning a factor of 40 to 50 over a mere 10 to 12 hours. For the first time, we have constrained the X-ray Power Spectral Density (PSD) of the source to 0.1 Hz, corresponding to a temporal frequency of 10,000 Hz in a galactic X-ray binary (GXRB) with a mass of 10 M_{\odot}. No extra high-frequency break/bend or any quasi-periodic oscillations are found. Through detailed analysis of energy-dependent PSDs, we found that the PSD normalization, the high-frequency PSD slope as well as the bending frequency remains consistent across all energies within the 0.3-3 keV band, revealing the presence of a constant temperature corona. These significant findings impose critical constraints on current models of X-ray emission and variability in AGN.

description: The focal-plane detector, the X-ray Integral Field Unit (X-IFU), on-board ESA's Athena space telescope is a transition edge sensor (TES) microcalorimeter array with 1.5k pixels, designed to provide spatially-resolved, high-resolution spectroscopy over the energy range 0.2-12 keV. The onboard event processor uses a digital optimal filter to determine the pulse-height of the measured current pulse from every X-ray photon striking the array. A modified optimal filter called the 0-padding filter has recently been proposed. This is a truncated version of the standard optimal filter and has been shown to provide comparable energy resolution but with the benefit of reduced computational expense. Whereas the standard optimal filter has zero integral and is not sensitive to variations in the DC level of the measured signal, the integral of the 0-padded version is non-zero and thus is more sensitive to fluctuations in DC signal over time. In this work, we explore the effect of 0-padding on the energy scale calibration using data from 250-pixels in a prototype Athena X-IFU array, measured over the range 1.3-12 keV.

description: The human vaginal microbiome (HVM) is closely associated with the health of the host. In particular, bacterial vaginosis, a condition where vaginal lactobacilli are reduced dramatically by an overgrowth of various other bacteria, has been linked to increased risk of sexually transmitted infectious diseases, including HIV, and preterm birth. Recent culture-independent studies leveraging next-generation sequencing technology have revealed that the HVM composition differs between women and changes over time. However, questions remain as to the underlying mechanisms and culture-dependent studies are needed for further elucidation of the HVM’s genotype-phenotype relationships and system-level properties in vivo. In this work, we have adapted a previously developed microdroplet-based high-throughput cultivation platform for the investigation of vaginal bacteria using the cervicovaginal fluid (CVF) as cultivation medium. Using undiluted CVF collected with Softdiscs discs, we observed the growth of L. iners in microdroplets containing CVF pooled from samples with a high prevalence of L. crispatus. Although demonstrated with L. iners, this work establishes a new framework for culturing microorganisms under clinically-relevant conditions ex vivo using minute volumes of host fluids; it can be further extended and adapted for addressing numerous questions about the HVM and other complex microbiomes.

description: The dielectric constant, which defines the polarization of the media, is a key quantity in condensed matter. It determines several electronic and optoelectronic properties important for a plethora of modern technologies from computer memory to field effect transistors and communication circuits. Moreover, the importance of the dielectric constant in describing electromagnetic interactions through screening plays a critical role in understanding fundamental molecular interactions. Here we show that despite its fundamental transcendence, the dielectric constant does not define unequivocally the dielectric properties of two-dimensional (2D) materials due to the locality of their electrostatic screening. Instead, the electronic polarizability correctly captures the dielectric nature of a 2D material which is united to other physical quantities in an atomically thin layer. We reveal a long-sought universal formalism where electronic, geometrical and dielectric properties are intrinsically correlated through the polarizability opening the door to probe quantities yet not directly measurable including the real covalent thickness of a layer. We unify the concept of dielectric properties in any material dimension finding a global dielectric anisotropy index defining their controllability through dimensionality.

description: O artigo tem como objetivo discutir sobre a verticalização da agricultura familiar, pois a partir dela cria-se uma rede entre os agentes da sociedade, uma nova prática social, que vai além da melhoria da renda do produtor. Busca-se realizar essa reflexão para que se possam apresentar alternativas que tenham maior poder de contraposição a modelos excludentes, pois frente às turbulências da globalização (alta tecnologia, redução de emprego e desigualdade social) a valorização da agricultura familiar ameniza a questão social que assola o País. Diante disto, discorrer acerca da possibilidade da verticalização da agricultura familiar, tornam-se relevantes os conceitos de capital social e abordagem sistêmica, como elementos-chave para essa reflexão. Dessa forma, foi realizada uma revisão teórica sobre capital social, desenvolvimento rural sustentável, abordagem sistêmica e, por fim, apresenta-se a discussão sobre a verticalização da agricultura familiar.
