description: Deep observations with the Very Large Array of A0620-00, performed in 2005 August, resulted in the first detection of radio emission from a black hole binary at X-ray luminosities as low as 10^{-8.5} times the Eddington limit. The measured radio flux density, of 51 \pm 7 microJy at 8.5 GHz, is the lowest reported for an X-ray binary system so far, and is interpreted in terms of partially self-absorbed synchrotron emission from outflowing plasma. Making use of the estimated outer accretion rate of A0620-00 in quiescence, we demonstrate that the outflow kinetic power must be energetically comparable to the total accretion power associated with such rate, if it was to reach the black hole with the standard radiative efficiency of 10 per cent. This favours a model for quiescence in which a radiatively inefficient outflow accounts for a sizable fraction of the missing energy, and, in turn, substantially affects the overall dynamics of the accretion flow. Simultaneous observations in the X-ray band, with Chandra, confirm the validity of a non-linear radio/X-ray correlation for hard state black hole binaries down to low quiescent luminosities, thereby contradicting some theoretical expectations. Taking the mass term into account, the A0620-00 data lie on the extrapolation of the so called Fundamental Plane of black hole activity, which has thus been extended by more than 2 orders of magnitude in radio and X-ray luminosity. With the addition of the A0620-00 point, the plane relation provides an empirical proof for the scale-invariance of the jet-accretion coupling in accreting black holes over the entire parameter space observable with current instrumentation.

description: Alicyclobacillus spp. are thermoacidophilic sporeformers that have significant impact on the pasteurized juice industry. Better detection and control methods are needed to minimize Alicyclobacillus related spoilage. The objective of this research is to improve existing detection and control methods by (1) the investigation of basic characteristics of guaiacol producing Alicyclobacillus and development of a novel detection method; and (2) the evaluation of Alicyclobacillus control method during storage and processing. Differences in growth characteristics were observed but not significant between guaiacol producing and non-guaiacol producing Alicyclobacillus. Enzyme and carbohydrate utilization profiles were variable depending on test isolates. Guaiacol formation was detectable within 12 h at 43 C and further accelerated under microaerophilic conditions. The newly developed SK2 agar provides selective identification of guaiacol producing Alicyclobacillus with a 95% correct identification rate. SK2 agar is the first known media providing selective isolation of guaiacol producing Alicyclobacillus. The effectiveness of aqueous and gas chlorine dioxide against Alicyclobacillus spores has been demonstrated. Greater than five log reductions were observed following 1 min and 1 h exposures to 120 ppm ClO2(aq) and 4.32 ppm ClO2(g), respectively.

description: Chondritic meteorites primarily contain millimeter-sized spherical objects, the so-called chondrules; however, the co-accretion process of chondrules and matrix grains is not yet understood. In this study, we investigate the ejection process of chondrules via collisions of fluffy aggregates composed of chondrules and matrices. We reveal that fluffy aggregates cannot grow into planetesimals without losing chondrules if we assume that the chondrite parent bodies are formed via direct aggregation of similar-sized aggregates. Therefore, an examination of other growth pathways is necessary to explain the formation of rocky planetesimals in our solar system.

description: SSHOC Dataverse team is working on the extension of the Dataverse data repository with new tools intended for the DDI community. DDI explorer was fully integrated in the latest version of Dataverse and introduced to the CESSDA partners as a part of basic functionality that can be used both locally or deployed in the Cloud. The new DDI converter tool was designed in order to help DDI community to migrate their datasets to Dataverse from other systems like NESSTAR and use DDI explorer features to browse data visually and do basic statistical analysis online. The migration process relies on the XSLT mappings curated by DDI community and reused by the networked application that can be connected to any Dataverse instance.

description: A novel complex-phase steel alloy is conceived with a deliberately unstable austenite, $γ$, phase that enables the deformation-induced martensitic transformations (DIMT) to be explored at low levels of plastic strain. The DIMT was thus explored, in-situ and non-destructively, using both far-field Three-Dimensional X-Ray Diffraction (3DXRD) and Electron Back-Scatter Diffraction (EBSD). Substantial $α'$ martensite formation was observed under 10% applied strain with EBSD, and many $\varepsilon$ grain formation events were captured with 3DXRD, indicative of the indirect transformation of martensite via the reaction $γ\rightarrow \varepsilon \rightarrow α'$. Using $\varepsilon$ grain formation as a direct measurement of $γ$ grain stability, the influence of several microstructural properties, such as grain size, orientation and neighbourhood configuration, on $γ$ stability have been identified. Larger $γ$ grains were found to be less stable than smaller grains. Any $γ$ grains oriented with {100} parallel to the loading direction preferentially transformed with lower stresses. Parent $\varepsilon$-forming $γ$ grains possessed a neighbourhood with increased ferritic/martensitic volume fraction. This finding shows, unambiguously, that $α$/$α'$ promotes $\varepsilon$ formation in neighbouring grains. The minimum strain work criterion model for $\varepsilon$ variant prediction was also evaluated, which worked well for most grains. However, $\varepsilon$-forming grains with a lower stress were less well predicted by the model, indicating crystal-level behaviour must be considered for accurate $\varepsilon$ formation. The findings from this work are considered key for the future design of alloys where the deformation response can be controlled by tailoring microstructure and local or macroscopic crystal orientations.

description: Creating high-quality controllable 3D human models from multi-view RGB videos poses a significant challenge. Neural radiance fields (NeRFs) have demonstrated remarkable quality in reconstructing and free-viewpoint rendering of static as well as dynamic scenes. The extension to a controllable synthesis of dynamic human performances poses an exciting research question. In this paper, we introduce a novel NeRF-based framework for pose-dependent rendering of human performances. In our approach, the radiance field is warped around an SMPL body mesh, thereby creating a new surface-aligned representation. Our representation can be animated through skeletal joint parameters that are provided to the NeRF in addition to the viewpoint for pose dependent appearances. To achieve this, our representation includes the corresponding 2D UV coordinates on the mesh texture map and the distance between the query point and the mesh. To enable efficient learning despite mapping ambiguities and random visual variations, we introduce a novel remapping process that refines the mapped coordinates. Experiments demonstrate that our approach results in high-quality renderings for novel-view and novel-pose synthesis.

description: Advances in image restoration and enhancement techniques have led to discussion about how such algorithmscan be applied as a pre-processing step to improve automatic visual recognition. In principle, techniques like deblurring and super-resolution should yield improvements by de-emphasizing noise and increasing signal in an input image. But the historically divergent goals of the computational photography and visual recognition communities have created a significant need for more work in this direction. To facilitate new research, we introduce a new benchmark dataset called UG^2, which contains three difficult real-world scenarios: uncontrolled videos taken by UAVs and manned gliders, as well as controlled videos taken on the ground. Over 160,000 annotated frames forhundreds of ImageNet classes are available, which are used for baseline experiments that assess the impact of known and unknown image artifacts and other conditions on common deep learning-based object classification approaches. Further, current image restoration and enhancement techniques are evaluated by determining whether or not theyimprove baseline classification performance. Results showthat there is plenty of room for algorithmic innovation, making this dataset a useful tool going forward.

description: SnSe is a topical thermoelectric material with a low thermal conductivity which is linked to its unique crystal structure. We use low-temperature heat capacity measurements to demonstrate the presence of two characteristic vibrational energy scales in SnSe with Debye temperatures thetaD1 = 345(9) K and thetaD2 = 154(2) K. These hard and soft substructures are quantitatively linked to the strong and weak Sn-Se bonds in the crystal structure. The heat capacity model predicts the temperature evolution of the unit cell volume, confirming that this two-substructure model captures the basic thermal properties. Comparison with phonon calculations reveals that the soft substructure is associated with the low energy phonon modes that are responsible for the thermal transport. This suggests that searching for materials containing highly divergent bond distances should be a fruitful route for discovering low thermal conductivity materials.

Surface modification and fatigue behavior of nitinol for load bearing implants

Subjects: Implants, Artificial -- Design and construction

description: Musculoskeletal disorders are recognized amongst the most significant human health problems that exist today. Even though considerable research and development has gone towards understanding musculoskeletal disorders, there is still lack of bone replacement materials that are appropriate for restoring lost structures and functions, particularly for load-bearing applications. Many materials on the market today, such as titanium and stainless steel, suffer from significantly higher modulus than natural bone and low bioactivity leading to stress shielding and implant loosening over longer time use. Nitinol (NiTi) is an equiatomic intermetallic compound of nickel and titanium whose unique biomechanical and biological properties contributed to its increasing use as a biomaterial. An innovative method for creating dense and porous net shape NiTi alloy parts has been developed to improve biological properties while maintaining comparable or better mechanical properties than commercial materials that are currently in use. Laser engineered net shaping (LENS ) and surface electrochemistry modification was used to create dense/porous samples and micro textured surfaces on NiTi parts, respectively. Porous implants are known to promote cell adhesion and have a low elastic modulus, a combination that can significantly increase the life of an implant. However, porosity can significantly reduce the fatigue life of an implant, and very little work has been reported on the fatigue behavior of bulk porous metals, specifically on porous nitinol alloy. High-cycle rotating bending and compression-compression fatigue behavior of porous NiTi fabricated using LENS were studied. In cyclic compression loading, plastic strain increased with increasing porosity and it was evident that maximum strain was achieved during the first 50000 cycles and remained constant throughout the remaining loading. No failures were observed due to loading up to 150% of the yield strength. When subjected to rotary bending fatigue, samples demonstrated a high tolerance to failure, up to 50% of the yield stress. Using anodization, improvements to the surface wettability were made by lowering the contact angle from 32 to less than 5 , which prove to enhance the bioactivity of the nitinol surface in the cell study. The surface free energy was also calculated to show comparable properties to that of cpTi. Ni ion release was studied over a 8 week duration and found that anodization not only reduces the amount of metal ion release but also decreases the rate of release as well. This work was aimed at understanding the effects of porosity characteristics, microstructure, surface morphology and fatigue behavior of nitinol on its mechanical and biological properties.

description: A theoretical framework for emission originating from rapidly rotating oblate compact objects is described in detail. By using a Hamilton-Jacobi formalism, we show how the special relativistic rotational effects such as aberration of angles, Doppler boosting, and time dilatation naturally emerge from the general relativistic treatment of rotating compact objects. We use the Butterworth-Ipser metric expanded up to the second order in rotation and hence include effects of light bending, frame-dragging, and quadrupole deviations to our geodesic calculations. We also give detailed descriptions of the numerical algorithms used and provide an open source implementation of the numerical framework called bender. As an application, we study spectral line profiles (i.e., smearing kernels) from rapidly rotating oblate neutron stars. We find that in this metric description the second order quadrupole effects are not strong enough to produce narrow observable features in the spectral energy distribution for almost any physically realistic parameter combination, and hence, actually detecting them is unlikely. The full width at tenth-maximum and full width at half-maximum of the rotation smearing kernels are also reported for all viewing angles. These can be then used to quantitatively estimate the effects of rotational smearing on the observed spectra. We also calculate accurate pulse profiles and observer skymaps of emission from hot spots on rapidly rotating accreting millisecond pulsars. These allow us to quantify the strength of the pulse fractions one expects to observe from typical fast spinning millisecond pulsars.

description: A search for a heavy CP-odd Higgs boson, $A$, decaying into a $Z$ boson and a heavy CP-even Higgs boson, $H$, is presented. It uses the full LHC Run 2 dataset of $pp$ collisions at $\sqrt{s}=13$ TeV collected with the ATLAS detector, corresponding to an integrated luminosity of $140$ fb$^{-1}$. The search for $A\to ZH$ is performed in the $\ell^+\ell^- t\bar{t}$ and $ν\barνb\bar{b}$ final states and surpasses the reach of previous searches in different final states in the region with $m_H>350$ GeV and $m_A>800$ GeV. No significant deviation from the Standard Model expectation is found. Upper limits are placed on the production cross-section times the decay branching ratios. Limits with less model dependence are also presented as functions of the reconstructed $m(t\bar{t})$ and $m(b\bar{b})$ distributions in the $\ell^+\ell^- t\bar{t}$ and $ν\barνb\bar{b}$ channels, respectively. In addition, the results are interpreted in the context of two-Higgs-doublet models.

Behavioral assessment of aggression towards humans in the domestic dog
Creators: name: Donaldson, Tammy McCormick
Publisher: name: Washington State University
Year: 2010
Subjects: Aggressive behavior in animals

description: Behavioral assessment tools are used by companion animal professionals and animal rescue organizations to evaluate the risk of various behavioral problems in dogs. This dissertation encompasses three studies designed to assess the validity of such tools as predictors of canine aggression towards humans. In the first study, an evaluation was made of a graded behavioral assessment tool used in a program for transporting dogs between shelters to enhance adoption rates. The tool was found to have test-retest reliability within, but not between, shelters. Dogs that failed the assessment were subsequently more likely to be euthanized due to human-directed aggression than dogs that passed the assessment. However, behavior in the assessment was not a reliable predictor of overall owner reports of aggression towards people following adoption. The second study involved an investigation of a different behavioral assessment tool to identify behaviors exhibited during the assessment that were reliable in predicting humandirected-aggression following adoption in dogs subsequently returned to the shelter. Findings indicated that aggression towards people was predicted by discrete behaviors displayed during the assessment, with snapping, whirling and stiffening being associated with future bites at strangers, and growling and shying/cowering being associated with threatening both strangers and familiar people. The third study investigated the effectiveness of the same behavioral assessment tool in discriminating between owned dogs with and without a history of aggression towards humans. The assessment was reliable for identifying dogs that had previously bitten humans, which exhibited more lunging and less looking away from the tester than dogs with no history of aggression. This research indicates that behavior assessment has some predictive power in the detection of human-directed aggression in dogs. However, it was found that human factors involved in behavioral assessment at shelters, and in the reporting of aggressive behavior by dog owners, influenced the validity of data used to determine outcomes for dogs relinquished to shelters. An improved understanding of dog non-verbal communication and human-related factors is needed to improve predictability in assessment, thereby reducing the risk of canine aggression towards humans.

multiagent system

description: When coordinating their actions to accomplish a mission, the agents in a multi-agent system may use a collaboration algorithm to determine which agent performs which task. This paper describes a novel data-driven metareasoning approach that generates a metareasoning policy that the agents can use whenever they must collaborate to assign tasks. This metareasoning approach collects data about the performance of the algorithms at many decision points and uses this data to train a set of surrogate models that can estimate the expected performance of different algorithms. This yields a metareasoning policy that, based on the current state of the system, estimated the algorithms’ expected performance and chose the best one. For a ship protection scenario, computational results show that one version of the metareasoning policy performed as well as the best component algorithm but required less computational effort. The proposed data-driven metareasoning approach could be a promising tool for developing policies to control multi-agent autonomous systems.

description: We study the dynamics of excitonic insulators coupled to phonons. Without phonon couplings, the linear response is given by the damped amplitude oscillations of the order parameter with frequency equal to the minimum band gap. A phonon coupling to the interband transfer integral induces two types of long-lived collective oscillations of the amplitude, one originating from the phonon dynamics and the other from the phase mode, which becomes massive. We show that even for small phonon coupling, a photo-induced enhancement of the exciton condensation and the gap can be realized. Using the Anderson pseudo-spin picture, we argue that the origin of the enhancement is a cooperative effect of the massive phase mode and the Hartree shift induced by the photo excitation. We also discuss how the enhancement of the order and the collective modes can be observed with time-resolved photo-emission spectroscopy.

description: Machine learning based solvers have garnered much attention in physical simulation and scientific computing, with a prominent example, physics-informed neural networks (PINNs). However, PINNs often struggle to solve high-frequency and multi-scale PDEs, which can be due to spectral bias during neural network training. To address this problem, we resort to the Gaussian process (GP) framework. To flexibly capture the dominant frequencies, we model the power spectrum of the PDE solution with a student $t$ mixture or Gaussian mixture. We apply the inverse Fourier transform to obtain the covariance function (by Wiener-Khinchin theorem). The covariance derived from the Gaussian mixture spectrum corresponds to the known spectral mixture kernel. Next, we estimate the mixture weights in the log domain, which we show is equivalent to placing a Jeffreys prior. It automatically induces sparsity, prunes excessive frequencies, and adjusts the remaining toward the ground truth. Third, to enable efficient and scalable computation on massive collocation points, which are critical to capture high frequencies, we place the collocation points on a grid, and multiply our covariance function at each input dimension. We use the GP conditional mean to predict the solution and its derivatives so as to fit the boundary condition and the equation itself. As a result, we can derive a Kronecker product structure in the covariance matrix. We use Kronecker product properties and multilinear algebra to promote computational efficiency and scalability, without low-rank approximations. We show the advantage of our method in systematic experiments. The code is released at \url{https://github.com/xuangu-fang/Gaussian-Process-Slover-for-High-Freq-PDE}.

description: We analyze the physical properties of post-starburst AGN SDSS J085338.27+033246.1 according to its optical spectrum and discuss its implications on AGN's evolution. The spectra PCA method is developed to extract emission lines and absorption features from the total light spectrum. The emission-line analysis indicates that the object can be classified as a NLS1 with FeII/H$β_{\rm{B}}=2.4\pm0.2$, large Eddington ratio ($\sim0.34$), small black hole mass ($\sim1.1\times10^{7}M_{\odot}$) and intermediately strong radio emission. A simple SSP model indicates that the absorption features are reproduced by a $\sim$100 Myr old starburst with a mass of $\sim7\times10^{9}M_{\odot}$ rather well. The current SFR $\sim3.0M_{\odot}\rm{yr^{-1}}$ inferred from the [OII] emission is much smaller than the past average SFR$\sim70M_{\odot}\rm{yr^{-1}}$, however. The line ratio diagnosis using the BPT diagrams indicates that the narrow emission lines are almost entirely emitted from HII regions. We further discuss a possible evolutionary path that links AGN and starburst phenomena.

description: The recent discovery of the planetary system hosted by the ultracool dwarf star TRAPPIST-1 could open new perspectives into the investigation of planetary climates of Earth-sized exoplanets, their atmospheres and their possible habitability. In this paper, we use a simple climate-vegetation energy-balance model to study the climate of the seven TRAPPIST-1 planets and the climate dependence on the global albedo, on the fraction of vegetation that could cover their surfaces and on the different greenhouse conditions. The model allows us to investigate whether liquid water could be maintained on the planetary surfaces (i.e., by defining a "surface water zone") in different planetary conditions, with or without the presence of greenhouse effect. It is shown that planet TRAPPIST-1d seems to be the most stable from an Earth-like perspective, since it resides in the surface water zone for a wide range of reasonable values of the model parameters. Moreover, according to the model outer planets (f, g and h) cannot host liquid water on their surfaces, even for Earth-like conditions, entering a snowball state. Although very simple, the model allows to extract the main features of the TRAPPIST-1 planetary climates.

description: NP-hard optimization problems scale very rapidly with problem size, becoming unsolvable with brute force methods, even with supercomputing resources. Typically, such problems have been approximated with heuristics. However, these methods still take a long time and are not guaranteed to find an optimal solution. Quantum computing offers the possibility of producing significant speed-up and improved solution quality. Current quantum annealing (QA) devices are designed to solve difficult optimization problems, but they are limited by hardware size and qubit connectivity restrictions. We present a novel heterogeneous computing stack that combines QA and classical machine learning, allowing the use of QA on problems larger than the hardware limits of the quantum device. These results represent experiments on a real-world problem represented by the weighted k-clique problem. Through this experiment, we provide insight into the state of quantum machine learning.

Kekulé valence bond order in the Hubbard model on the honeycomb lattice with possible lattice distortions for graphene

description: We investigate if and how the valence-bond-solid (VBS) state emerges in the Hubbard model on the honeycomb lattice when the Peierls-type electron-lattice coupling is introduced. We consider all possible lattice-distortion patterns allowed for this lattice model for graphene which preserve the reflection symmetry and determine the most stable configuration in the adiabatic limit by using an unbiased quantum Monte Carlo method. The VBS phase with Kekulé dimerization is found to appear as an intermediate phase between a semimetal and an antiferromagnetic Mott insulator for a moderately rigid lattice. This implies that the undistorted semimetallic graphene can be driven into the VBS phase by applying strain, accompanied by the single-particle excitation gap opening.

Cortical involvement of GHRH-GHRHR in sleep regulation

Subjects: Growth hormone releasing factor -- Receptors

description: Growth hormone releasing hormone (GHRH) is involved in the regulation of non-rapid eye movement sleep (NREMS). The hypothalamus is a well-characterized sleep-promoting site of action for GHRH. However, GHRH may also act in the cortex to influence sleep; application of GHRH to the surface of the cortex changes electroencephalogram (EEG) delta power, a measure of the NREMS intensity. GHRH and the GHRH receptor (GHRHR) and their mRNAs are detectable in the rat cortex and the expression of cortical GHRHR is activity-dependent. Here we microinject a GHRH antagonist or GHRHR siRNA (siGHRHR) onto the surface of somatosensory cortex of the rat brain. The unilateral application of the GHRH antagonist ipsilaterally decreased EEG delta wave power during NREMS, but not wakefulness, during the initial 40 min after injection. Insufficient REMS epochs occurred during this 40 min period to allow power analyses during REMS. Similarly, injection of siGHRHR reduced the expression of GHRHR in the cortex and suppressed EEG delta wave power of NREMS during 20-24 hr after injection. Using the Fura-2 calcium imaging technique, we detected cultured cortical cells that respond to GHRH with an increase of intracellular calcium. This increase was due to the influx of extracellular calcium. Approximately 18% of these GHRH responsive cells are GABAergic as illustrated by GAD67 immunostaining. Double labeling for GAD67 and GHRHR in vitro and in vivo indicated that 32% and 20% of GHRHR containing cells are GAD-immunoreactive, respectively. Therefore, in the cortex, the number of GHRH responsive cells that are GABAergic are fewer than in the hypothalamus, where most of these cells are GABAergic. Our data suggest that endogenous cortical GHRH activates local cortical cells to affect EEG delta wave power state-specifically. Results are also consistent with the hypothesis that GHRH contributes to local network state regulation.

description: Modern time series gene expression and other omics data sets have enabled unprecedented resolution of the dynamics of cellular processes such as cell cycle and response to pharmaceutical compounds. In anticipation of the proliferation of time series data sets in the near future, we use the Hopfield model, a recurrent neural network based on spin glasses, to model the dynamics of cell cycle in HeLa (human cervical cancer) and S. cerevisiae cells. We study some of the rich dynamical properties of these cyclic Hopfield systems, including the ability of populations of simulated cells to recreate experimental expression data and the effects of noise on the dynamics. Next, we use a genetic algorithm to identify sets of genes which, when selectively inhibited by local external fields representing gene silencing compounds such as kinase inhibitors, disrupt the encoded cell cycle. We find, for example, that inhibiting the set of four kinases BRD4, MAPK1, NEK7, and YES1 in HeLa cells causes simulated cells to accumulate in the M phase. Finally, we suggest possible improvements and extensions to our model.
