Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: A near-threshold 4He(g,n) cross-section measurement has been performed at MAX-lab. Tagged photons from 23 < Eg < 42 MeV were directed toward a liquid 4He target, and neutrons were detected by time-of-flight in two liquid-scintillator arrays. Seven-point angular distributions were measured for eight photon energies. The results are compared to experimental data measured at comparable energies and Recoil-Corrected Continuum Shell Model, Resonating Group Method, and recent Hyperspherical-Harmonic Expansion calculations. The angle-integrated cross-section data is peaked at a photon energy of about 28 MeV, in disagreement with the value recommended by Calarco, Berman, and Donnelly in 1983.

description: Abstract: "The CMU Planetary Rover project is developing a six-legged walking robot capable of autonomously navigating, exploring, and acquiring samples in rugged, unknown environments. This report describes an integrated software system capable of navigating a single leg of the robot over rugged terrain. The leg, based on an early design of the Ambler Planetary Rover, is suspended below a carriage that slides along rails.To walk, the system creates an elevation map of the terrain from laser scanner images, plans an appropriate foothold based on terrain and geometric constraints, weaves the leg through the terrain to position it above the foothold, contacts the terrain with the foot, and applies force enough to advance the carriage along the rails. Walking both forward and backward, the system has traversed hundreds of meters of rugged terrain including obstacles too tall to step over, trenches too deep to step in, closely spaced obstacles, and sand hills.The implemented systems consists of a number of task-specific processes (two for planning, two for perception, one for real-time control) and a central control process that directs the flow of communication between processes."

description: Increasing agricultural and food trade is often considered means for food safety risks to spread more rapidly. Also climate change has a potential effect on prevalence of foodborne diseases including zoonosis. Risks are also often used as a pretext for protectionism. Therefore, commensurate and reliable rules become more and more important. We have created an analytical framework which aims at structuring the interrelations between international agricultural and food trade and food safety. According to the results there is a direct connection between agricultural and food trade and food safety. The severity of food safety risks depends on e.g. the nature of the traded goods and the magnitude of the effects of changes in trade and consumption on food system. Furthermore, the study suggests that preventing and minimising the effects of food safety crises are of utmost importance to the society and preparedness for such events is mandatory.

description: In the FirstLight project, we have used ~300 cosmological, zoom-in simulations to determine the star-formation histories of distinct first galaxies with stellar masses between Ms=10^6 and 3 x 10^9 Msun during cosmic dawn (z=5-15). The evolution of the star formation rate (SFR) in each galaxy is complex and diverse, characterized by bursts of star formation. Overall, first galaxies spend 70% of their time in SF bursts. A sample of 1000 of these bursts indicates that the typical burst at z=6 has a specific SFR (sSFR) maximum of 5-15 Gyr^-1 with an effective width of ~100 Myr, one tenth of the age of the Universe at that redshift. A quarter of the bursts populate a tail with very high sSFR maxima of 20-30 Gyr^-1 and significantly shorter timescales of ~40-80 Myr. This diversity of bursts sets the mean and the mass-dependent scatter of the star-forming main sequence. This scatter is driven by a population of low-mass, Ms < 10^8 Msun, quiescent galaxies. The mean sSFR and the burst maximum at fixed mass increase with redshift, with the later always being a factor ~2 higher than the former. This implies sSFR maxima of ~20-60 Gyr^-1 at z=9-10. The SFR histories are publicly available at the FirstLight website.

description: Globular clusters could harbor massive central black holes (BHs), just as galaxies do. So far, no unambiguous detection of a massive BH has been reported for any globular cluster. However, the dense core-collapsed cluster M15 seems to be a good candidate. I review the available photometric and kinematic data for this cluster. Both are consistent with a BH of approximately 2000 solar masses, although such a BH is not unambiguously required by the data. I discuss some ongoing studies with Keck and HST which should shed more light on this issue in the coming years.

description: Excerpts from the report: Costs of containers and of loading, transportation, and other handling make up a substantial part of the total costs of marketing cantaloups and various other fruits and vegetables. The size, shape, construction, and other characteristics of containers affect to a large extent the efficiency and economy with which most perishable foods can be packed, handled, transported, and refrigerated during marketing. These same characteristics of containers also determine how well perishable commodities can be protected against physical damage and spoilage during marketing. Several different types of containers for cantaloups have been developed and introduced during the past three shipping seasons. This study was made to evaluate the new designs as well as methods of loading and handling the containers. The new containers included (1) an improved nailed wooden container, known as the WGA (Western Growers Association) panel-end crate, (2) a full-telescope fiberboard container, and (3) a new type of wirebound container. This study was undertaken to (1) determine whether the new containers would significantly reduce container damage and melon bruising, (2) measure the economies that might be achieved from use of the new containers, and (3) assist shippers in developing and testing the most effective method of loading and bracing the new containers for shipment.

Extended Perturbation Theory for the Local Density Distribution Function

description: Perturbation theory makes it possible to calculate the probability distribution function (PDF) of the large scale density field in the small variance limit. For top hat smoothing and scale-free Gaussian initial fluctuations, the result depends only on the linear variance, sigma_linear, and its logarithmic derivative with respect to the filtering scale -(n_linear+3)=dlog sigma_linear^2/dlog L (Bernardeau 1994). In this paper, we measure the PDF and its low-order moments in scale-free simulations evolved well into the nonlinear regime and compare the results with the above predictions, assuming that the spectral index and the variance are adjustable parameters, n_eff and sigma_eff=sigma, where sigma is the true, nonlinear variance. With these additional degrees of freedom, results from perturbation theory provide a good fit of the PDFs, even in the highly nonlinear regime. The value of n_eff is of course equal to n_linear when sigma << 1, and it decreases with increasing sigma. A nearly flat plateau is reached when sigma >> 1. In this regime, the difference between n_eff and n_linear increases when n_linear decreases. For initial power-spectra with n_linear=-2,-1,0,+1, we find n_eff ~ -9,-3,-1,-0.5 when sigma^2 ~ 100.

description: We present a method for defining a hybrid control system capable of simultaneously addressing the global navigation and control problem for a convex-bodied wheeled mobile robot navigating amongst obstacles. The method uses parameterized continuous local feedback control policies that ensure safe operation over local regions of the free configuration space; each local policy is designed to respect nonholonomic constraints, bounds on velocities (inputs), and obstacles in the environment. The hybrid control system makes use of a collection of these local control policies in concert with discrete planning tools in order to plan, and replan in the face of changing conditions, while preserving the safety and convergence guarantees of the underlying control policies. In this paper, we provide details of the system models and policy definitions used to validate the approach in simulation and experiment with a convex-bodied wheeled mobile robot. This work is one of the first that combines formal planning with continuous feedback control guarantees for systems subject to nonholonomic constraints, input bounds, and non-trivial body shape.

Exclusion of standard $\hbarω$ gravitons by LIGO observation

description: Dyson (2013) argued that the extraordinarily large number of gravitons in a gravitational wave makes them impossible to be resolved as individual particles. While true, it is shown in this paper that a LIGO interferometric detector also undergoes frequent and {\it discrete} quantum interactions with an incident gravitational wave, in such a way as to allow the exchange of energy and momentum between the wave and the detector. This opens the door to another way of finding gravitons. The most basic form of an interaction is the first order Fermi acceleration (deceleration) of a laser photon as it is reflected by a test mass mirror oscillating in the gravitational wave, resulting in a frequency blueshift (redshift) of the photon depending on whether the mirror is advancing towards (receding from) the photon before the reflection. If e.g. a blueshift occurred, wave energy is absorbed and the oscillation will be damped. It is suggested that such energy exchanging interactions are responsible for the observed radiation reaction noise of LIGO (although the more common way of calculating the same amplitude for this noise is based on momentum considerations). Most importantly, in each interaction the detector absorbs or emits wave energy in amounts far smaller than the standard graviton energy $\hbarω$ where $ω$ is the angular frequency of the gravitational wave. This sets a very tight upper limit on the quantization of the wave energy, viz. it must be at least $\approx 10^{11}$ times below $\hbarω$, independently of the value of $ω$ itself.

description: The analysis presented in this paper suggests that a credence good such as non-chlorinated chicken could be supplied by firms, either voluntarily or due to pressure from activists. If UK consumers have a high willingness to pay for non-chlorinated chicken, it may be supplied at the same time as imported chlorinated chicken. The level of any private standard for UK poultry processing will be determined by the costs of supplying non-chlorinated chicken, the extent of competition in the UK poultry processing sector, and the nature of the UK’s post-Brexit trading arrangements.

Integral field spectrograph

description: Integral field spectrographs (IFS) have transformed studies of low-redshift spatially resolved galaxies as they provide simultaneous spectral coverage over contiguous spatial regions. IFS surveys of galaxies have allowed for observations of the spatially varying physical diagnostics of galaxy disks. Though IFS instruments have been traditionally limited to small fields of view (FOV), on the order of 100 square arcseconds, constraining the extent to which IFS studies can map the most nearby galaxies. Small FOV have also restricted IFS studies of large galaxy samples to pre-selected targets. Scaling up the fields of IFS instruments is challenging due to the limited number of spatial elements that can be imaged on a single CCD. To cost effectively scale up IFS capability in order to observe larger fields, the Visible Integral-field Replicable Unit Spectrograph (VIRUS) utilizes massive replication on an unprecedented 100-fold scale to be able to image ∼35,000 fibers over a ∼22 arcminute FOV with a single observation. VIRUS consists of up to 78 replicable units, each with two integral field spectrograph channels. The VIRUS design takes advantage of large-scale replication of simple units to significantly reduce engineering and production costs of building a facility instrument of this scale. With VIRUS being 156 realizations of the same spectrograph and the first to be replicated on this massive scale, I present analysis that uncovers the statistical variations in performance of these units along with an assessment of cost/tolerance trade offs of scaling up instrument capabilities through massively replicated designs. The VIRUS instrument was designed to conduct the Hobby Eberly Telescope Dark Energy Experiment (HETDEX) which intends to build a sample of nearly a million Lyα emitting galaxies (LAEs) from 1.9

description: This paper provides an overview of fabrication and design of CMOS-based microelectromechanical systems with emphasis on inertial sensor and data storage applications. High-aspect-ratio (4.4:1) microstructures can be fabricated using conventional CMOS processing followed by a sequence of maskless dry-etching steps. The CMOS dielectric and metallization layers, normally used for electrical interconnect, serve a dual function as a composite metal/dielectric structural material. Reactive-ion etching produces near vertical sidewalls, enabling micromechanical beam widths and gap spacings down to 1.2 μm. The process is tailored for design of lateral electrostatic actuators as well as capacitive position and motion sensors. Tight integration of the microstructures with CMOS provides an opportunity to make low-noise sensor interface circuitry, and to include the signal processing needed to manage arrayed sensor-and-actuator systems-on-a-chip. Novel actuator and sensor topologies can be designed by embedding multiple isolated conductors into the microstructures. An additional post-CMOS processing sequence produces platinum tips on the movable microstructures. These tips are being explored for use in probe-based data storage and tunneling sensor applications.

description: Mineral nitrogen in agriculture has increased greatly food supply and allowed the historical population growth of the past century. Its intensive use is nevertheless the source of numerous environmental issues and remains a major challenge for policymakers. In this paper, we explore the eects of a public policy aiming at halving mineral nitrogen use over European agriculture. We investigate the impacts in terms of agricultural production, prices, land use change and the resulting consequences for ecosystems and biodiversity. We present a modeling framework that links a set of models covering agronomic, economic, land-based, and biodiversity processes. We propose a comprehensive analysis of the underlying mechanism at play. At the EU level and regarding the results only from agronomic and supply-side models, reducing nitrogen implies lower crop yields, lower prots, and less agricultural land. However, following the results from global scale economic models that take into account market feedbacks, the policy implies an increase in food prices and the substitution of nitrogen input for land. Land allocation is then modied at the global level as the result of a \leakage" of the European scale nitrogen policy.

description: In recent years, wine tourism is one of the emerging forms of tourism that attracts more and more tourists and more and more businesses are investing in it.
Wine tourism combines the activities of vine cultivation, wine production and tourism activities in a mixture that meets the needs of wine tourists for entertainment, education and knowledge.
Opportunities to visit and tour wineries are a key part of wine tourism, which is a popular form of alternative tourism that adds significant value to the tourism sector. It generates an income for businesses in the sector and is also a means of promoting the wines produced, increasing their popularity and sales.
In this thesis, the service of organized visit to a local winery will be examined and analyzed. More specifically, the main characteristics of the offered service will be analyzed and its analysis will be carried out with the help of the SERVQUAL model. Also, the way of managing the service offered by the winery will be presented and its evaluation will be carried out using a specialized questionnaire. The results will include the estimation of the difference (gaps) between the perceived and expected services based on the customers' opinions.

description: [abridged] Aims: We test the effects of re-orienting jets from an active galactic nucleus (AGN) on the intracluster medium in a galaxy cluster environment with short central cooling time. We investigate appearance and properties of the resulting cavities, and the efficiency of jets in providing near-isotropic heating to the cooling cluster core. Methods: We use numerical simulations to explore four models of jets over several active/inactive cycles. We keep the jet power and duration fixed, varying only the jet angle prescription. We track the total energy of the intracluster medium (ICM) in the cluster core over time, and the fraction of the jet energy transferred to the ICM, paying attention to where the energy is deposited. We also compare synthetic X-ray images of the simulated cluster to actual observations. Results: Jets whose re-orientation is minimal ($\lesssim 20^{\circ}$) typically produce conical structures of interconnected cavities, with the opening angle of the cones being $\sim 15-20^{\circ}$, extending to $\sim 300$ kpc from the cluster centre. Such jets transfer about $60\%$ of their energy to the ICM, yet they are not very efficient at heating the cluster core, as the jet energy is deposited further out. Jets that re-orient by $\gtrsim 20^{\circ}$ generally produce multiple pairs of detached cavities. Although smaller, these cavities are inflated within the central 50~kpc and are more isotropically distributed, resulting in more effective heating of the core. Such jets, over few hundreds Myr, can deposit up to $80\%$ of their energy where it is required. Consequently, these models come the closest to an heating/cooling balance and to mitigating runaway cooling of the core, even though all models have identical power/duration profiles. Additionally, the corresponding synthetic X-ray images exhibit structures closely resembling those seen in real cool-core clusters.

description: Current unmanned vehicle systems enable exploration of and travel through remote areas, but demand significant communications resources and constant human operation. DARPA and the US Army have recognized these limitations and are now pursuing semi-autonomous vehicle systems in the Future Combat Systems (FCS) program. FCS places high demands on robotic systems, which must assess mobility hazards under all weather conditions, day and night, in the presence of smoke and other airborne obscurants, and with the possibility of communications dropouts. Perhaps the most challenging mobility hazard is the "negative obstacle", such as a hole or ditch. These hazards are difficult to see from the ground, limiting maximum vehicle speed. From the air, however, these obstacles are often far easier to detect. In this context, we present a novel semi-autonomous unmanned ground vehicle (UGV) that includes a dedicated unmanned air vehicle - a "Flying Eye" (FE) - that flies ahead of the UGV to detect holes and other hazards before the onboard UGV sensors would otherwise be able detect them. This concept is shown in Figure 1. The FE can be considered a longer-range “scout” to explore terrain before the UGV must traverse it, allowing the UGV to avoid certain areas entirely because of hazards or cul-de-sacs detected by the FE. The UGV itself carries its own extensive sensor suite to address the broad range of operating conditions at slower speeds and to confirm the hazards seen from the air. In the fully developed system, the UGV will deploy the FE from a landing bay on the back of the UGV. For covert operations, the FE will return to its landing bay on the back of the UGV. This paper presents the current prototype system as well as initial field experiments on the performance of the system.

description: Excerpts from the report: The Foreign Agricultural Service in 1957 began a project which represents a first step toward defining the kinds of rice that move in international trade and the kinds preferred by consumers in importing countries. Its goal is to help establish some basis for comparing the competitive position of a particular rice in a particular market. Lack of international grades in rice as well as any semblance of a worldwide international market have always made this comparison difficult. Using the U.S. Rice Standards as a measuring stick, the samples collected under the project in the rice producing and consuming countries of the world were analyzed in a two-part study. The first, reported on here, has to do with the types and quality of the rice; the second, which will be published later, concerns itself with the physical and chemical characteristics of the samples. For this study the grading analysis on all samples was performed by the rice grading service of the Agricultural Marketing Service at New Orleans, La. The laboratory testing for chemical and physical factors was divided according to their specialized research interests between the Texas Rice and Pasture Improvement Station in Beaumont, Tex., the Southern Utilization Laboratory (ARS) at New Orleans, and the Western Utilization Laboratory (ARS) at Albany, Calif. Cooking quality evaluations were made on a selected group of samples by Agricultural Research Service in Beltsville, Md.

description: The Weak Gravity Conjecture (WGC) was proposed to constrain Effective Field Theories (EFTs) with Abelian gauge symmetry coupled to gravity. In this article, I study the WGC from low energy observers' perspective, and revisit the issue of to what extent the WGC actually constrains EFTs. For this purpose, for a given EFT, I introduce associated idealized low energy observers who only have access to the energy scale below the UV cut-off scale of the EFT. In the framework of EFT, there is a clear difference between the particles lighter than the UV cut-off scale and the particles which are heavier than the UV cut-off scale, as the lighter particles can be created below the UV cut-off scale while the heavier particles are not. This difference implies that the knowledge of the low energy observers on the stable heavy particles can be limited, as the availability of the stable heavy particles is determined by the environment prepared by some UV theory unknown to the low energy observers. The limitation of the knowledge of the low energy observers regarding the stable heavy particles whose mass is above the UV cut-off scale of the EFT leads to the limitation of the WGC for constraining EFTs. To illustrate these points in an example, I analyze a model proposed by Saraswat arXiv:1608.06951 which respects the WGC at high energy, but which may appear to violate the WGC for the low energy observers. Implications of the analysis to the bottom-up model buildings using EFTs are discussed.

description: We present the combined results on electron-pair production in 158 GeV/n {Pb-Au} ($\sqrt{s}$= 17.2 GeV) collisions taken at the CERN SPS in 1995 and 1996, and give a detailed account of the data analysis. The enhancement over the reference of neutral meson decays amounts to a factor of 2.31$\pm0.19 (stat.)\pm0.55 (syst.)\pm0.69 (decays)$ for semi-central collisions (28% $σ/σ_{geo}$) when yields are integrated over $m>$ 200 MeV/$c^2$ in invariant mass. The measured yield, its stronger-than-linear scaling with $N_{ch}$, and the dominance of low pair $p_t$ strongly suggest an interpretation as {\it thermal radiation} from pion annihilation in the hadronic fireball. The shape of the excess centring at $m\approx$ 500 MeV/$c^2$, however, cannot be described without strong medium modifications of the $ρ$ meson. The results are put into perspective by comparison to predictions from Brown-Rho scaling governed by chiral symmetry restoration, and from the spectral-function many-body treatment in which the approach to the phase boundary is less explicit.

Gravitational Radiation from Strongly Magnetized White Dwarfs

description: The magnetic fields of white dwarfs distort their shape generating an anisotropic moment of inertia. A magnetized white dwarf which rotates obliquely relative to the symmetry axis has a mass quadrupole moment which varies in time, so it will emit gravitational radiation. LISA may be able to detect the gravitational waves from two nearby, quickly rotating white dwarfs.

description: Excerpts from the report: Golden Delicious apples have a skin characteristic that allows relatively rapid moisture loss even in cold storage. It is well known that Golden Delicious apples may become shriveled and spongy after about 3 or 4 months in cold storage even though the relative humidity is as high as 85 percent. The shriveling is apparent when fruit has lost 3 to 5 percent of its original weight. If moisture loss is prevented, Golden Delicious apples have a long life in refrigerated storage and remain free of most physiological storage disorders. This report summarizes the results of a study conducted from 1953 to 1960 on polyethylene box liners for Golden Delicious apples. The purpose of these studies was to evaluate sealed, non- sealed, and perforated liners for preventing moisture loss and aiding quality retention of eastern-grown Golden Delicious in storage. Results of film-liner studies with other apple varieties will be published separately.
Supersymmetric QCD corrections to the W-boson width

description: We calculate the one-loop supersymmetric QCD corrections to the width of the $W$-boson. We find that these are of order $\sim {{ α_s} \over π} {1 \over 20} { {M^2_W} \over {M_S^2}} Γ_{u {\bar d}}$, where $M_S$ is the supersymmetry breaking scale and $ Γ_{u {\bar d}}$ the tree level hadronic width for $W^+ \rightarrow u {\bar d} $. Due to the appearance of the suppression factor $\sim {1 \over 20}$ these are at least two orders of magnitude smaller than the standard QCD corrections $\sim {{ α_s} \over π} Γ_{u {\bar d}}$ and hence of the order of the two-loop electroweak effects. Therefore supersymmetric QCD corrections will only be of relevance once experiments reach that level of accuracy.

description: Abstract: "This report reviews the state of the art in systems that innovate. The review concentrates more on the techniques used in these systems rather than what the system actually did. This report reviews some of the important issues for DA systems that work in domains requiring non-routine and innovative approaches to problem solving. This part of the report covers issues such as analogy & metaphor, exploration & discovery and creativity. Readers who wish to get a broader sense of the techniques used in DA systems may refer to the following papers [Gross 86, Stefik 80, Tong 86a, Mostow 85, Nilsson 80, Sriram 86, Ullman & Dietterich 87, Tong 86b]."

description: Shipdeck landing is one of the most challenging tasks for a rotorcraft. Current autonomous rotorcraft use shipdeck mounted transponders to measure the relative pose of the vehicle to the landing pad. This tracking system is not only expensive but renders an unequipped ship unlandable. We address the challenge of tracking shipdeck without additional infrastructure on the deck. We present two methods based on video and lidar that are able to track the shipdeck starting at a considerable distance from the ship. This redundant sensor design enables us to have two independent tracking systems. We show the results of the tracking algorithms in 3 different environments, 1. ﬁeld testing results on actual helicopter ﬂights, 2. in simulation with a moving shipdeck for lidar based tracking and 3. in laboratory using an occluded and moving scaled model of a landing deck for camera based tracking. The complimentary modalities allow shipdeck tracking under varying conditions.
Stochastic Acceleration and Non-Thermal Radiation in Clusters of Galaxies

description: We calculate the distribution of electrons in clusters of galaxies, resulting from thermalization processes in the presence of stochastic acceleration due to plasma waves. We show that the electron distribution can deviate from a Maxwell-Boltzmann distribution, due to the effect of the stochastic energy gain, provided waves can be sustained against damping. The non-thermal tail of electrons can generate as bremsstrahlung emission a flux of hard X-rays compatible with the ones recently detected in some clusters of galaxies.

description: Selective data return leverages onboard data analysis to allocate limited bandwidth resources during remote exploration. Here we present an adaptive method to subsample image sequences for downlink. We treat selective data return as a compression problem in which the explorer agent transmits the subset of measurements that are most informative with respect to the complete dataset. Experiments demonstrate selective downlink of navigation imagery by a rover during autonomous geologic investigations in the Atacama desert of Chile. Here automatic analysis identifies informative images using classifications based on natural image statistics. Image texture analysis, together with a context-sensitive Hidden Markov Model representation, permits adaptive downlink in response to geologic unit boundaries. Selective data return improves the science content of returned data for this geologic mapping task.

Lattice Energetics and Correlation-Driven Metal-Insulator Transitions: The Case of Ca$_2$RuO$_4$
Creators: name: Han, Qiang

Publisher: name: arXiv
Year: 2018
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: This Letter uses density functional, dynamical mean field, and Landau-theory methods to elucidate the interplay of electronic and structural energetics in the Mott metal-insulator transition. A Landau-theory free energy is presented that incorporates the electronic energetics, the coupling of the electronic state to local distortions and the coupling of local distortions to long-wavelength strains. The theory is applied to Ca$_2$RuO$_4$. The change in lattice energy across the metal-insulator transition is comparable to the change in electronic energy. Important consequences are a strongly first order transition, a sensitive dependence of the phase boundary on pressure and that the geometrical constraints on in-plane lattice parameter associated with epitaxial growth on a substrate typically change the lattice energetics enough to eliminate the metal-insulator transition entirely.
