description: Quantum sensing, quantum networking and communication, and quantum computing have attracted significant attention recently, as these quantum technologies offer significant advantages over existing technologies. In order to accelerate the commercialization of these quantum technologies the workforce must be equipped with the necessary skills. Through a qualitative study of the quantum industry, in a series of interviews with 21 U.S. companies carried out in Fall 2019, we describe the types of activities being carried out in the quantum industry, profile the types of jobs that exist, and describe the skills valued across the quantum industry, as well as in each type of job. The current routes into the quantum industry are detailed, providing a picture of the current role of higher education in training the quantum workforce. Finally, we present the training and hiring challenges the quantum industry is facing and how higher education may optimize the important role it is currently playing.

description: Dwarf galaxies (M*<10^9 Msun) are key drivers of mass assembly in high mass galaxies, but relatively little is understood about the assembly of dwarf galaxies themselves. Using the \textsc{NewHorizon} cosmological simulation (40 pc spatial resolution), we investigate how mergers and fly-bys drive the mass assembly and structural evolution of around 1000 field and group dwarfs up to z=0.5. We find that, while dwarf galaxies often exhibit disturbed morphologies (5 and 20 per cent are disturbed at z=1 and z=3 respectively), only a small proportion of the morphological disturbances seen in dwarf galaxies are driven by mergers at any redshift (for 10^9 Msun, mergers drive only 20 per cent morphological disturbances). They are instead primarily the result of interactions that do not end in a merger (e.g. fly-bys). Given the large fraction of apparently morphologically disturbed dwarf galaxies which are not, in fact, merging, this finding is particularly important to future studies identifying dwarf mergers and post-mergers morphologically at intermediate and high redshifts. Dwarfs typically undergo one major and one minor merger between z=5 and z=0.5, accounting for 10 per cent of their total stellar mass. Mergers can also drive moderate star formation enhancements at lower redshifts (3 or 4 times at z=1), but this accounts for only a few per cent of stellar mass in the dwarf regime given their infrequency. Non-merger interactions drive significantly smaller star formation enhancements (around two times), but their preponderance relative to mergers means they account for around 10 per cent of stellar mass formed in the dwarf regime.

description: This study examines whether the local competition for corn to produce ethanol has lead to significantly higher prices for farmers located close to ethanol plants. If any, such price premiums for spatial closeness would be in addition to the general level of corn price changes experienced by farmers throughout the U.S. The difference-in-differences estimation method is used to account for both time and location differences in order to measure the interaction of time and location effects. Using the USDA’s ARMS data, the results show that while prices in real terms have risen over time, farmers located close to ethanol plants have not received significantly higher prices than farmers living farther away from plants. These findings indicate that there is a lack of evidence for price premiums due to the spatial closeness to ethanol plants.

description: The induced Chern-Simons term for a paired electron state is calculated in the quantum Hall system by using a field theory on the von Neumann lattice. The coefficient of the Chern-Simons term, which is the Hall conductance, has not only the usual term proportional to a filling factor due to P (parity) & T (time reversal) symmetry breaking but also correction terms due to P & T & U(1) symmetry breaking. The correction term essentially comes from the Nambu-Goldstone mode and depends on an infrared limit. It is shown that the correction term is related to a topological number of a gap function in the momentum space.

The branching fractions ${\cal B}(χ_{cJ}\to K^*(892)^0\bar K^*(892)^0)$ $(J = 0,1,2)$ are determined to be $(1.55 \pm 0.35 \pm 0.30)\times 10^{-3}$, $(1.58 \pm 0.32 \pm 0.29)\times 10^{-3}$, and $(4.67 \pm 0.55 \pm 0.85)\times 10^{-3}$ for the $χ_{c0}$, $χ_{c1}$ and $χ_{c2}$ decays, respectively, where the first errors are statistical and the second are systematic. The significances of these signals are about 4.2$σ$, 4.3$σ$, and 7.5$σ$, respectively.

Correspondence between the adhesion model and the velocity dispersion for the cosmological fluid
Creators: name: Tatekawa, Takayuki
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Basing our discussion on the Lagrangian description of hydrodynamics, we studied the evolution of density fluctuation for nonlinear cosmological dynamics. Adhesion approximation (AA) is known as a phenomenological model that describes the nonlinear evolution of density fluctuation rather well and that does not form a caustic. In addition to this model, we have benefited from discussion of the relation between artificial viscosity in AA and velocity dispersion. Moreover, we found it useful to regard whether the velocity dispersion is isotropic produces effective `pressure' or viscosity terms. In this paper, we analyze plane- and spherical-symmetric cases and compare AA with Lagrangian models where pressure is given by a polytropic equation of state. From our analyses, the pressure model undergoes evolution similar to that of AA until reaching a quasi-nonlinear regime. Compared with the results of a numerical calculation, the linear approximation of the pressure model seems rather good until a quasi-nonlinear regime develops. However, because of oscillation arising from the Jeans instability, we could not produce a stable nonlinear structure.

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: The lattice Wess-Zumino model written in terms of the Ginsparg-Wilson relation is invariant under a generalized supersymmetry transformation which is determined by an iterative procedure in the coupling constant. By studying the associated Ward-Takahashi identity up to order $g^2$ we show that this lattice supersymmetry automatically leads to restoration of continuum supersymmetry without fine tuning. In particular, the scalar and fermion renormalization wave functions coincide.

description: We propose a new geometry and/or topology of a single extra dimension whose Kaluza-Klein excitations do appear at much higher scale than the inverse of the length/volume. For a single extra dimenion with volume $Nπρ$ which is made of N intervals with size $πρ$ attached at one point, Kaluza-Klein excitations can appear at $1/ρ$ rather than $1/Nρ$ which can hide the signal of the extra dimenion sufficiently for large N. The geometry considered here can be thought of a world volume theory of self intersecting branes or an effective description of complicated higher dimensional geometry such as Calabi-Yau with genus or multi-throat configurations. This opens a wide new domain of possible compactifications which deserves a serious investigation.

description: Local governments in the United States use a wide range of tools to preserve rural landscapes. Some of these tools, like the purchase or transfer of development rights, are generally welcomed by farmers and other large landowners. Other tools, like increasing the minimum lot size in a town’s agricultural zone, are more controversial because they are believed to have negative effects on landowner wealth. In this contentious policy environment, it would be useful to know which land use tools actually work to control residential growth, thus achieving the consensual objective of rural preservation. It is reasonable to suppose that large-lot zoning and open space preservation will both reduce the number of homes in a community when it is fully developed. The short and medium-term effects of these policies, however, are less certain. Indeed, there is some evidence that permanently-preserved open space increases short-run home building through an “amenity magnet” effect. Similarly, an increase in minimum lot size could trigger the immediate development of agricultural land by reducing the option value of waiting. This study uses data on 83 communities in the Highlands region of New Jersey to help answer these questions about the unintended consequences of these two rural conservation tools. The dataset includes GIS-based information on developable land, open space inventory, and minimum lot size zoning for the period 1995 to 2002. The study concludes that the relationship between minimum lot size and homebuilding in a community can be described as a concave quadratic. The pace of homebuilding rises to a maximum at a weighted average minimum lot size of 4.15, and then starts to fall. The percentage of a community that is permanently-preserved open space was found to have no significant effect on homebuilding, other things equal.

description: In this paper, we investigate comparatively the behaviors of quantum discord and concurrence for Werner states based on two bipartite entangled squeezed states. The maximally entangled squeezed states are regarded as a perfect-Werner states, while the non-maximally entangled squeezed states are called quasi-Werner states. We show that, the behavior of the quantum correlations keep unchanged for these two types of states. However, the quantum correlations amount presents in perfect-Werner states is very higher than that presents in quasi-Werner ones. Furthermore, we show that for large values of squeezed parameter the quasi-Werner states approaches the perfect-Werner states qualitatively and quantitatively.

description: Relationship marketing and customer relationship management have taken a central position in marketing strategy in the past two decades. Most theories of relationship marketing emphasize the role of trust and commitment on customer purchase intention however a recent meta-analysis indicates that other mediating mechanisms are at work. This research is in addition to trust & commitment, which other mediators generate positive word of mouth & results in increased customer purchase intention. In research self administered 250 questionnaires with seven points likert scale was developed & distributed among five big cities of Pakistan e.g. Multan, Lahore, Islamabad, Faisalabad & Karachi. Data was collected from consumers of five telecom operators e.g. Telenor, Mobilink, Warid, Ufone & Zong. For analysis of ten hypotheses of this paper Regression analysis and ANOVA technique are used. As probability systematic sampling technique is used for data collection there is no risk associated with sampling & data collection. As a result we propose that gratitude is an important missing mediator in the extant of RM model. We proposes to develop & validate a theoretical framework that integrates gratitude in RM network parallel to trust & commitment which results in positive word of mouth & increased purchase intention. This study is limited to telecom sector only, it’s a cross sectional study. This research is valid for the culture & economic set up of Pakistan
Thermal Activation Barriers for Creation and Annihilation of Magnetic Droplet Solitons in the Presence of Spin Transfer Torque

description: We study noise-induced creation and annihilation of magnetic droplet solitons in experimental parameter regions in which they are linearly stable against drift. Exploiting the rotational symmetry of the problem, we transform to the reference frame rotating with the droplet soliton and introduce an effective potential energy that accounts for the work done against spin-transfer torque to rotate the magnetization between two different orientations. We use this function to compute the activation barrier in both directions between the uniform magnetization state and the droplet soliton state for a variety of nanocontact radii and currents. We investigate droplet soliton structures with both zero and nonzero spin-torque asymmetry parameter. Our approach can be applied to estimate activation barriers for dynamical systems where non-gradient terms can be absorbed by changes of reference frames, and suggests a technique applicable to extended systems that may not be uniformly magnetized.

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

description: In the context of split supersymmetry, the gaugino mass spectrum seems to be very important to satisfy the dark matter content of the universe and the gauge coupling unification. In this paper, we have considered various sources of gaugino masses in the context of unified models. We show that the gaugino mass spectrum varies in different unification pictures. In the context of SU(5), we have found that the Bino/Wino mass ratio can be close to one at the weak scale which is helpful to satisfy the WMAP data. The gluino/Wino mass ratio is also different from the usual scenario of unified gaugino masses. The gaugino masses can be around one TeV and m_SUSY is chosen so that the gluino mass does not create any cosmological problem. In the context of the Pati-Salam model, we show that the gluino mass can be made very heavy even after maintaining the unification of the gauge couplings.

subject: FOS: Physical sciences

description: We use the astrometric and photometric data from Gaia Data Release 2 and line-of-sight velocities from various other surveys to study the 3d structure and kinematics of the Sagittarius dwarf galaxy. The combination of photometric and astrometric data makes it possible to obtain a very clean separation of Sgr member stars from the Milky Way foreground; our final catalogue contains ~2.6e5 candidate members with magnitudes G<18, more than half of them being red clump stars. We construct and analyze maps of the mean proper motion and its dispersion over the region ~30x12 degrees, which show a number of interesting features. The intrinsic 3d density distribution (orientation, thickness) is strongly constrained by kinematics; we find that the remnant is a prolate structure with the major axis pointing at 45deg from the orbital velocity and extending up to ~5 kpc, where it transitions into the stream. We perform a large suite of N-body simulations of a disrupting Sgr galaxy as it orbits the Milky Way over the past 2.5 Gyr, which are tailored to reproduce the observed properties of the remnant (not the stream). The richness of available constraints means that only a narrow range of parameters produce a final state consistent with observations. The total mass of the remnant is ~4e8 Msun, of which roughly a quarter resides in stars. The galaxy is significantly out of equilibrium, and even its central density is below the limit required to withstand tidal forces. We conclude that the Sgr galaxy will likely be disrupted over the next Gyr.

description: We estimate the impact of direct payments under the 2002 Farm Act on the credit terms of farm operators, specifically the interest rate on short-term operating loans. In the analysis, we control for farm financial characteristic, farm operator characteristics, and other factors. Using data from the Agricultural Resource Management Survey (ARMS) for the year 2007, we show that as the proportion of base acres to total operated acres increases, interest rates decline by a small but statistically significant amount. This implies that direct payments lead to lower operating costs through better credit terms. Lower operating costs may in turn allow some farmers to produce on land that would otherwise be unprofitable to operate.
Microbial methylation and volatilization of arsenic
Creators: name: Lehr, Corinne Rita
Publisher: name: University of British Columbia
Year: 2009

description: The basis of the "Toxic Gas Hypothesis" of Sudden Infant Death Syndrome (SIDS) is that the microorganisms present on infants bedding materials volatilize sufficient arsenic, antimony or phosphorus from these materials to be acutely toxic to an infant. The volatilization of arsenic by aerobic microorganisms isolated from new sheepskin bedding materials, as well as from materials used by a healthy infant and by an infant who perished of SIDS was examined. Three arsenic-methylating fungi were isolated from a piece of sheepskin bedding material on which an infant perished of SIDS. These fungi form trimethylarsenic(V) species, precursors to volatile trimethylarsine. Their ribosomal RNA PCR products were used to identify the fungi as Scopulariopsis koningii, Fomitopsis pinicola and Penicillium gladioli. S. koningii, as well as two other sheepskin isolates, Mycobacterium neoaurum and Acinetobacter junii are human pathogens which should also be of concern in connection with SIDS. Few microogransism have been shown to methylate antimony. S. koningii methylated the antimony(III) compounds, potassium antimonyl tartrate and antimony trioxide yielding trimethylantimony. P. gladioli and S. koningii volatilized arsenic as trimethylarsine, but only under conditions such that the production of sufficient trimethylarsine to be acutely toxic to an infant is urilikely. These fungi did not volatilize antimony. Very little is known about the demethylation of methylarsenicals. One of the sheepskin isolates, Mycobacterium neoaurum, demethylated methylarsenic compounds to mixtures of As(III) and As(V). There was some evidence that MMA(V) is reductively demethylated to As(III) which is then oxidized to As(V). Iodide decreased the demethylation of MMA(V) by M. neoaurum and increased the methylation of MMA(V) by both P. gladioli and S. koningii. The techniques developed for studying the volatilization of arsenic by the microorganisms on sheepskin bedding materials were applied to two other environments - garden waste compost and Meager creek hot springs. Composting of garden waste yielded iodomethane. Aerobic incubation of microbial mats and sediment from Meager creek hot springs yielded trimethylarsine and trimethylstibine.

description: A continuous-time path integral Quantum Monte Carlo method using the directed-loop algorithm is developed to simulate the Anderson single-impurity model in the occupation number basis. Although the method suffers from a sign problem at low temperatures, the new algorithm has many advantages over conventional algorithms. For example, the model can be easily simulated in the Kondo limit without time discretization errors. Further, many observables including the impurity susceptibility and a variety of fermionic observables can be calculated efficiently. Finally the new approach allows us to explore a general technique, called the multi-level algorithm, to solve the sign problem. We find that the multi-level algorithm is able to generate an exponentially large number of configurations with an effort that grows as a polynomial in inverse temperature such that configurations with a positive sign dominate over those with negative signs. Our algorithm can be easily generalized to other multi-impurity problems.

Asheville, NC: U.S. Department of Agriculture, Forest Service, Southern Research Station: 125-149.
Although the annual FHM reports address annual spatial extent and patterns of insect and disease detections, there has been no comprehensive long-term analysis of Insect and Disease Survey (IDS) data in the FHM reports. To examine medium-term trends in insect and disease damage to the forests of the United States, we organized and analyzed 20 years of IDS data, then produced an assessment of trends in forest area exposed to insects and disease in multiple timeframes and within four Resource Planning Act (RPA) Assessment regions. We found that the tree canopy area affected by mortality agents has been consistently large across the three most recent 5-year assessment periods, with regional differences in temporal patterns of area exposed to mortality. Insects have been much more widespread agents of mortality than diseases, with bark beetles consistently the most important mortality agents across regions and over time, especially in the West. Nationally, the tree canopy area affected by nonnative invasive agents of mortality and defoliation has remained relatively consistent over time, though these agents have had a larger relative impact on forests in the North. Tree canopy area affected by defoliation agents has remained relatively consistent over time and has usually exceeded or equaled the area affected by mortality agents. Evaluating trends in these threats at a national scale provides context to managers attempting to understand the implications and scope of current forest health threats.

Reproducible fabrication of large-area highly crystalline films is, however, still a challenge. Here, we report the fabrication of epitaxially aligned PtSe2 films using one-zone selenization of pre-sputtered platinum layers. We have studied the influence of the growth conditions on the structural and electrical properties of the films prepared from Pt layers with different initial thickness. The best results were obtained for PtSe2 layers grown at elevated temperatures (600 °C). The films exhibit signatures for a long-range in-plane ordering resembling an epitaxial growth. Charge carrier mobility determined by Hall-effect measurements is up to 24 cm2/V.s in these films.

Forest fire occurrence outside the historic range of frequency and intensity can result in extensive economic and ecological impacts. The detection of regional patterns of fire occurrence density can allow for the identification of areas at greatest risk of significant impact and for the selection of locations for more intensive analysis. In 2018, the number of satellite-detected forest fire occurrences recorded for the conterminous States was very close to the average for the previous 17 years of data collection. Ecoregion sections in northwestern California/southwestern Oregon, northeastern Nevada, and north-central Washington had the highest forest fire occurrence density per 100 km2 of forested area. Geographic hot spots of high fire occurrence density were detected in these same areas, as well as in the Sierra Nevada and north-central Utah. Ecoregion sections in northwestern California/southwestern Oregon, western Wyoming, northern and eastern Utah, northwestern and south-central Colorado, northeastern New Mexico, and southern Florida experienced greater fire occurrence density than normal compared to the previous 17-year mean and accounting for variability over time. Alaska experienced low fire occurrence densities across the State. The eastern edge of the Big Island of Hawai‘i had a relatively high fire occurrence density because of a dramatic volcanic eruption. Fire occurrence density in Puerto Rico was slightly less than in the 17 preceding years.

Monitoring the occurrence of forest pest and pathogen outbreaks is important at regional scales because of the significant impact insects and disease can have on forest health across landscapes. National Insect and Disease Survey data collected in 2018 by the Forest Health Protection program of the Forest Service and partners in State agencies identified 56 different mortality-causing agents and complexes on 2.13 million ha and 56 defoliating agents and complexes on approximately 1.72 million ha in the conterminous United States. In the Western States, bark beetles (especially fir engraver, spruce beetle, mountain pine beetle, and western pine beetle) were the primary cause of geographic hot spots of forest mortality. In the Eastern States, emerald ash borer infestation resulted in several geographic hot spots of mortality. Hot spots of defoliation were associated with western spruce budworm, Swiss needle cast, pandora moth, and Douglas-fir tussock moth in the West, and with baldcypress leafroller, forest tent caterpillar, gypsy moth, spruce budworm, and browntail moth in the East. In Alaska, spruce beetle was by far the most widely detected mortality agent, and aspen leafminer and birch leafminer were the most commonly found defoliators. In Hawaii, surveyors identified approximately 46 000 ha of mortality, much of which may have been caused by rapid ʻōhiʻa death.

Healthy ecosystems are those that are stable and sustainable, able to maintain their organization and autonomy over time while remaining resilient to stress (Costanza 1992). Healthy forests are vital to our future (Edmonds and others 2011), and consistent, large-scale, and long-term monitoring of key indicators of forest health status, change, and trends is necessary to identify forest resources deteriorating across large regions (Riitters and Tkacz 2004). The Forest Health Monitoring (FHM) program of the Forest Service, U.S. Department of Agriculture, with cooperating researchers within and outside the Forest Service and with State partners, quantifies status and trends in the health of U.S. forests (ch. 1). The analyses and results outlined in sections 1 and 2 of this FHM annual national report offer a snapshot of the current condition of U.S. forests from a national or multi-State regional perspective, incorporating baseline investigations of forest ecosystem health, examinations of change over time in forest health metrics, and assessments of developing threats to forest stability and sustainability. For datasets collected on an annual basis, analyses are presented from 2018 data. For datasets collected over several years, analyses are presented at a longer temporal scale. Finally, section 3 of this report presents summaries of results from recently completed Evaluation Monitoring (EM) projects that have been funded through the FHM national program to determine the extent, severity, and/or causes of specific forest health problems (FHM 2018).

description: Speech is a critical biomarker for Huntington Disease (HD), with changes in speech increasing in severity as the disease progresses. Speech analyses are currently conducted using either transcriptions created manually by trained professionals or using global rating scales. Manual transcription is both expensive and time-consuming and global rating scales may lack sufficient sensitivity and fidelity. Ultimately, what is needed is an unobtrusive measure that can cheaply and continuously track disease progression. We present first steps towards the development of such a system, demonstrating the ability to automatically differentiate between healthy controls and individuals with HD using speech cues. The results provide evidence that objective analyses can be used to support clinical diagnoses, moving towards the tracking of symptomatology outside of laboratory and clinical environments.

description: In this position paper we analyse the impact of the proposed NIS 2.0 directive as published by the European Commission in December 2020 on entities that maintain and operate the domain name servers for their own organisational and affiliated domains. The proposal for the revised Directive on Security of Network and Information Systems (draft NIS 2) inadvertently makes many organisations in both the private and academic sector subject to a regulatory regime for ‘essential services’. The draft directive, aiming to improve the cybersecurity posture and risk management of organisations that provide essential and important services to the economy and society, includes in its definition of ‘essential’ entities of the Digital infrastructure all DNS service providers that provide ‘authoritative’ name resolution for domain names. The paper proposes specific changes to improve the NIS 2.0 draft directive in aligning with the intended aims of reaching a high common level of cybersecurity across the European Union.

description: The paper examines agricultural production and productivity growth in two Central Asian countries – Tajikistan and Uzbekistan. Both countries are characterized by a significant shift of resources from the traditional Soviet model of collective agriculture to more market-compliant individual and family farming. In both countries, the beginning of the policy-driven switch to family farming around 1997 coincided with the beginning of recovery in agriculture, namely resumption of agricultural growth after a phase of transition decline since 1991. In addition to growth in total agricultural production, we also observe significant increases in productivity of both land and labor since 1997. These observations suggest that productivity growth may be attributable to the changes in farming structure in Central Asia. To check this conjecture we assess the sources of growth by applying the standard Solow growth accounting methodology. Using time series of country statistics for farms of different organizational forms, we decompose the growth in output into growth in the resource base (extensive growth) and growth in productivity (intensive growth). Solow growth accounting clearly shows that, first, much of the growth at the country level is attributable to increases in productivity rather than increases in resources and, second, the increases in productivity in family farms (especially household plots) outstrip the increases in productivity in former collective and state farms. These findings confirm that the recovery of agricultural production in Central Asia has been driven largely by productivity increases, and it is the individual farms that are the main source of agricultural productivity increases.
