description: Spatial linear transforms that process multiple parallel analog signals to simplify downstream signal processing find widespread use in multi-antenna communication systems, machine learning inference, data compression, audio and ultrasound applications, among many others. In the past, a wide range of mixed-signal as well as digital spatial transform circuits have been proposed---it is, however, a longstanding question whether analog or digital transforms are superior in terms of throughput, power, and area. In this paper, we focus on Hadamard transforms and perform a systematic comparison of state-of-the-art analog and digital circuits implementing spatial transforms in the same 65\,nm CMOS technology. We analyze the trade-offs between throughput, power, and area, and we identify regimes in which mixed-signal or digital Hadamard transforms are preferable. Our comparison reveals that (i) there is no clear winner and (ii) analog-to-digital conversion is often dominating area and energy efficiency---and not the spatial transform.

description: At the beginning of a Java computer programming course, nine students in an undergraduate class and nine students in a graduate class completed a web-based programmed instruction tutoring system that taught a simple computer program. All students exited the tutor with an identical level of skill, at least as determined by the tutor’s required terminal performance, which involved writing the program and passing multiple-choice tests on the program’s elements. Before entering and after exiting the tutor, students completed a test of rule-based performance that required applications of general programming principles to solve novel problems. In both classes, the number of correct rule answers observed before entering the tutor did not predict the number of learn units that students subsequently used to complete the tutor. However, the frequency of learn units was inversely related to post-tutor rule-test performance, i.e., as the number of learn units used in the tutor increased over students, the number of correct answers on the post-tutor rule test decreased. Since time to complete the tutor was unrelated to learn unit frequency, these data suggest that high achieving students may have generated autoclitic learn units while using the tutor. Interteaching, as an occasion for generating and sharing interlocking learn units, may be an effective complement to programmed instruction in promoting optimal learning in all students.

description: Abstract

Concerns are increasing about heavy metals in soil that harm human health and the integrity of ecosystems. Traditional treatment methods are insufficient to solve the problem. Therefore, new and sustainable methods should be investigated. Removal of heavy metals from the soil matrix through microbial and chemical treatments are a great concern these days. Many chemical methods for the soil improvement involve the use of lime, phosphate, zeolites, and chelating agents. The application of these changes also changed the physical and chemical properties of the soil, led to the formation of stable metal complexes or the precipitation of poorly soluble metals. Although chemical treatment is fast and effective, its long-term impact on the environment is worth considering. Alternatively, bacteria can metabolize the contaminated soil by removing the heavy metals, which is the basic concept of microbial remediation. In addition to iron transfer, bacteria and viruses can reduce iron mobility and facilitate plant growth or mineralization. This method of bioremediation is generally environmentally friendly because it employs the natural processes and minimizes the need for external inputs. However, environmental conditions and other soil diseases can affect its performance. A combination of chemical and microbial remediation strategies can provide an integrated approach to remediating heavy metals in soil. The interaction between chemical treatments and microbial methods may provide further solutions in terms of an effective remediation of heavy metals contamination in soil.

description: Alluvial aquifer systems produce up to 60% of groundwater extracted in Australia. Identifying solute sources to these fresh water reservoirs is vital for their long-term sustainable management. In this thesis, new environmental tracer techniques are presented for quantifying the contributions of various processes to groundwater solute loads in semi-arid alluvial aquifers, extending the range of methods available for characterising solute sources in similar settings around the world. The methods are demonstrated in a surface water and groundwater study of the Lower Murrumbidgee Groundwater Management Area of south-east Australia's Murray Basin. Equations derived using Cl/Br ratios are used to quantify the input of chloride salts to dissolved chloride in waters subjected to evaporation and transpiration. The equations are applied to assess the contributions of halite to groundwater salinity in the Lower Murrumbidgee, where Cl/Br ratios are heterogeneous. Low, uniform Cl/Br ratios suggest negligible halite dissolution in the catchment's east while a systematic increase in Cl/Br ratios suggests up to 50% of dissolved chloride in the west could be from halite. Numerical simulations of the basin-scale "cyclic salt" conceptual groundwater salinisation model are used to quantify meteoric inputs to groundwater and to identify where additional processes not in the conceptual model contribute to aquifer salinity. Groundwater quantity in the study area is shown to depend on the leakage rate of the Murrumbidgee River to regional aquifers, but groundwater quality depends on the rate of cyclic salt input from the vadose zone. Solute distribution in irrigated areas deviates from the regional trend. Results indicate irrigation return flows have mobilised solutes in the unsaturated zone, but in-situ dissolution of soluble minerals does not significantly contribute to aquifer salinity. Stable silicon isotopes are used to examine spatial and temporal variations in silicate weathering in the Lower Murrumbidgee, where silica accounts for up to 30% of total dissolved solids in low-salinity groundwaters. A new conceptual model of silicon isotope fractionation during silicate weathering is presented and an existing mathematical model of isotope fractionation is adapted to calculate silicon isotope composition in solution. Fractionation is shown to be pathway-dependent, greatest in weathering processes that sequester high proportions of silica in secondary phases. Silicon isotope data from the Lower Murrumbidgee indicates that weathering intensity in the catchment may have increased over the last 20 000 years, and surface water 30Si values indicate a similar increase in the headwater catchments during the same period.

description: The design of a publisher's electronic interface can have a measurable effect on electronic journal usage statistics. A study of journal usage from six COUNTER-compliant publishers at thirty-two research institutions in the United States, the United Kingdom and Sweden indicates that the ratio of PDF to HTML views is not consistent across publisher interfaces, even after controlling for differences in publisher content. The number of fulltext downloads may be artificially inflated when publishers require users to view HTML versions before accessing PDF versions or when linking mechanisms, such as CrossRef, direct users to the full text, rather than the abstract, of each article. These results suggest that usage reports from COUNTER-compliant publishers are not directly comparable in their current form. One solution may be to modify publisher numbers with adjustment factors deemed to be representative of the benefit or disadvantage due to its interface. Standardization of some interface and linking protocols may obviate these differences and allow for more accurate cross-publisher comparisons.

description: Plans to pursue space expeditionary missions beyond Earth orbit have occasioned renewed  concern that crew behavioral health and performance effectiveness, along with spacecraft  habitability, will present major challenges to the success of spaceflight initiatives involving  unprecedented increases in time and distance on interplanetary voyages. A programmed  environment methodological approach that implements supportive performance and  research-based behavioral technologies can contribute to meeting these challenges in  furtherance of overcoming the ecologically constrained and inherently stressful circumstances  of long-duration spaceflight missions by members of confined microsocieties. This paper  presents the background context and rationale for applying behavior analytic methods and  procedures to support individual and crew performance effectiveness and adaptation for  long-duration spaceflight missions beyond Earth orbit, such as a mission to Mars.

description: Here we re-analyze the archival {\it Chandra} data for the central parts of the Centaurus\,A radio galaxy, aiming for a systematic investigation of the X-ray emission associated with the inner radio lobes in the system, and their immediate surroundings. In particular, we focus on four distinct features characterized by the soft excess with respect to the adjacent fields. Those include the two regions located at kpc distances from the nucleus to the West and East, the extended bow-shock structure to the South, and a fragment of a thin arc North from the center. The selected North, West, and South features coincide with the edges of the radio lobes, while the East structure is seemingly displaced from the radio-emitting plasma. Our X-ray spectral analysis reveals (i) a power-law emission component with photon index $Γ\sim 2$ in the North, East, and South regions, and (ii) a dense (number density $\sim 0.3$\,cm$^{-3}$) and relatively cold (temperature $\sim 0.2$\,keV) gas in the East and West regions. The power-law emission is consistent with the synchrotron continuum generated at the edges of the radio structure, and implies that the efficiency of the electron acceleration at the terminal bow-shock does not vary dramatically over the inner lobes' extension. The presence of gaseous condensations, on the other hand, could possibly be understood in terms of a massive outflow from the central regions of the galaxy.

description: Star-forming (SF) regions embedded inside giant molecular clouds (GMCs) are potential contributors to Galactic gamma rays. The gamma-ray source 3FHL J1907.0+0713 is detected with a significance of roughly 13$σ$ in the 0.2 $-$ 300 GeV energy range after the removal of gamma-ray pulsation periods of PSR J1906+0722 from the Fermi-LAT data set of about 10 years. The energy spectrum of 3FHL J1907.0+0713 is best-fitted to a power law model with a spectral index of 2.26 $\pm$ 0.05. The CO($J$ = 1$-$0) data taken by NANTEN2 revealed that 3FHL J1907.0+0713 is overlapping with a GMC having a peak velocity of about 38 km s$^{-1}$. The best-fitting location of 3FHL J1907.0+0713 is measured to be approximately 0.13 degrees away from the Galactic supernova remnant (SNR) 3C 397 and it overlaps with a star that is associated with a bow-shock nebula. We show that there is no physical connection between 3FHL J1907.0+0713, 3C 397, as well as any positional coincidence with the pulsar. The spectrum of 3FHL J1907.0+0713 is fitting to both hadronic and leptonic gamma-ray emission models and the total luminosity at a distance of 2.6 kpc is calculated to be 1.1 $\times$ 10$^{34}$ erg s$^{-1}$. We also discuss possible SF origins of gamma rays from 3FHL J1907.0+0713, where SNRs, massive protostar outflows, stellar winds from runaway stars, colliding wind binaries, and young stellar clusters are considered as candidate sources.

description: Kontsevich's formality theorem states that the differential graded Lie algebra of multidifferential operators on a manifold M is L-infinity-quasi-isomorphic to its cohomology. The construction of the L-infinity map is given in terms of integrals of differential forms on configuration spaces of points in the upper half-plane. Here we consider configuration spaces of points in the disk and work equivariantly with respect to the rotation group. This leads to considering the differential graded Lie algebra of multivector fields endowed with a divergence operator. In the case of R^d with standard volume form, we obtain an L-infinity morphism of modules over this differential graded Lie algebra from cyclic chains of the algebra of functions to multivector fields. As a first application we give a construction of traces on algebras of functions with star-products associated with unimodular Poisson structures. The construction is based on the Batalin--Vilkovisky quantization of the Poisson sigma model on the disk and in particular on the treatment of its zero modes.

Effects of noise and hearing loss on the conversational behaviour of seniors

Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to investigate the effects of hearing loss and adverse listening conditions on the conversational patterns of seniors. A second goal was to determine what measures best describe these conversational patterns. Results were compared to those of a case study of a hard-of-hearing senior presented by Pichora-Fuller & Johnson (submitted). One normal-hearing and one hearing-impaired senior were selected for this study. Each subject participated in two conversations, one in an advantageous condition and one in an adverse, noisy listening condition. Participants were interviewed about their ability to understand the conversations. Further measures of comprehension included free and recognition recall tasks, a conversational fluency rating, and a detailed discourse analysis based on a transcript of the conversations. Of all the comprehension measures used, the recognition task appeared to be the most sensitive indicator of perceptual difficulty and comprehension of conversational detail. Free recall results were a good measure of relative memory for detail and gist across the different signal-to-noise ratio conditions. Results of the discourse analysis provided quantitative evidence that was able to support or contradict the comprehension difficulties indicated on the conversational fluency ratings. The discourse analysis procedure was too time-intensive to be- a viable clinical tool.' However, some aspects of the analysis, including production of new content, overt repair requests, and subtopic management, could be singled out as particularly helpful in identifying comprehension problems, indicating that a more selective analysis may suffice for clinical purposes. No marked differences in comprehension between the hearing-impaired and normal-hearing senior were observed for the conversations in advantageous listening conditions. In the adverse listening conditions, the normal-hearing participant reported greater effort, but his comprehension did not appear to be significantly affected. Results were consistent with the Pichora-Fuller & Johnson (submitted) study in that both hard-of-hearing seniors showed reduced comprehension of the conversations in adverse listening conditions on all of the comprehension measures. However, individual variables appeared to have a significant effect on conversational behaviour. In particular, the subject of the Pichora-Fuller & Johnson (submitted) study tended to conceal her hearing problems by feigning understanding, while the hearing-impaired senior of the present study appeared to initiate repairs whenever they were needed. It was evident from the results presented here that individual baseline information is essential to the assessment of conversational behaviour and comprehension difficulties.

description: In this paper we present an analytical study of a subgrid scale turbulence model of the three-dimensional magnetohydrodynamic (MHD) equations, inspired by the Navier-Stokes-alpha (also known as the viscous Camassa-Holm equations or the Lagrangian-averaged Navier-Stokes-alpha model). Specifically, we show the global well-posedness and regularity of solutions of a certain MHD-alpha model (which is a particular case of the Lagrangian averaged magnetohydrodynamic-alpha model without enhancing the dissipation for the magnetic field). We also introduce other subgrid scale turbulence models, inspired by the Leray-alpha and the modified Leray-alpha models of turbulence. Finally, we discuss the relation of the MHD-alpha model to the MHD equations by proving a convergence theorem, that is, as the length scale alpha tends to zero, a subsequence of solutions of the MHD-alpha equations converges to a certain solution (a Leray-Hopf solution) of the three-dimensional MHD equations.

description: Excerpts from the report Introduction: Approximately one-third of the land area of the United States, 737 million acres, is forested. Forests and associated range, wildlife, water, and recreation resources make substantial contributions to the national economy and to American life. The concern that harmful airborne pollutants, resulting primarily from human activity, could be affecting the health of the Nation's forests has become a major environmental, political, and scientific issue. Acidic deposition as an environmental problem can be traced back to Scandinavia in the mid-1950's, where studies focused on acidification of precipitation and surface waters. When findings began to indicate that many different stressors were interacting to cause declines, the research outlook had to be broadened beyond acid rain. Associated pollutants, such as ozone, were included in the research, along with a closer look at the role of drought, insects, and pathogens. The Forest Response Program (FRP) was formed in 1985 to study the effects of acidic deposition and ozone on threatened forests throughout the United States. This bulletin summarizes the accomplishments of the 5-year FRP.

We show that this minimal number can be obtained with invariants of degree at most $|G|n(q-1)$. In the non-modular case this construction can be improved to give invariants of degree at most $n(q-1)$. As examples we study separating invariants over the field $\mathbb{F}_2$ for two important representations of the symmetric group

description: A three-person team performance task (TPT) is described, and evaluative results are presented  under conditions of individual fixed ratios required to complete a work component and a team fixed ratio  required to complete a work component. After an initial team performed the task over four successive days,  a member was replaced with a novitiate, and the newly formed team performed the task over four  successive days thereafter. The results showed differences in performance metrics between the individual  and team ratio conditions and between the original and the reformed teams. When communications among  team members were permitted at the start of the last two sessions of the study, individual contributions by  the three members to the team ratio requirement were equivalent during the final session. The results show  the sensitivity of the task to individual and team performance requirements and to membership  replacement. They also show the impact of tactical decision making on work distributions. The range of  outcomes suggests the utility of this type of task to assess the status of a team and to act as a potential  countermeasure to team fragmentation.
Separating the Weak Lensing and Kinetic SZ Effects from CMB Temperature Maps

description: A new generation of CMB experiments will soon make sensitive high resolution maps of the microwave sky. At angular scales less than $\sim$10 arcminutes, most CMB anisotropies are generated at z $< 1000$, rather than at the surface of last scattering. Therefore, these maps potentially contain an enormous amount of information about the evolution of structure. Whereas spectral information can distinguish the thermal Sunyaev-Zeldovich (tSZ) effect from other anisotropies, the spectral form of anisotropies generated by the gravitational lensing and the kinetic Sunyaev-Zeldovich (kSZ) effects are identical. While spectrally identical, the statistical properties of these effects are different. We introduce a new real-space statistic, $_c$, and show that it is identically zero for weakly lensed primary anisotropies and, therefore, allows a direct measurement of the kSZ effect. Measuring this statistic can offer a new tool for studing the reionization epoch. Models with the same optical depth, but different reionization histories, can differ by more than a factor of 3 in the amplitude of the kSZ-generated non-Gaussian signal.

description: In the Einstein-Cartan framework the torsion-free conditions arise within the Hamiltonian treatment as second-class constraints. The standard strategy is to solve these constraints, eliminating the torsion from the classical theory, before quantization. Here we advocate leaving the torsion inside the other constraints before quantization, leading at first to wave functions that can be called ``kinematical'' with regards to the torsion, but not the other constraints. The torsion-free condition can then be imposed as a condition upon the physical wave packets one constructs, satisfying the usual uncertainty relations, and so with room for quantum fluctuations in the torsion. This alternative strategy has the surprising effect of clarifying the sense in which the wave functions solving an explicitly real theory are ``delta-function normalizable''. Such solutions with zero (or any fixed) torsion, should be interpreted as plane waves in torsion space. Properly constructed wave packets are therefore normalizable in the standard sense. Given that they are canonical duals, this statement applies equally well to the Chern-Simons state (connection representation) and the Hartle-Hawking wave function (metric representation). We show how, when torsion is taken into account, the Hartle-Hawking wave function is replaced by a Gauss-Airy function, with finite norm, which we call the Hartle-Hawking beam. The Chern-Simons state, instead, becomes a packet with a Gaussian probability distribution in connection space. We conclude the paper with two sections explaining how to generalize these results beyond minisuperspace.

A high-order semi-Lagrangian method for the consistent Monte-Carlo solution of stochastic Lagrangian drift-diffusion models coupled with Eulerian discontinuous spectral element method

description: The explicit semi-Lagrangian method method for solution of Lagrangian transport equations as developed in [Natarajan and Jacobs, Computer and Fluids, 2020] is adopted for the solution of stochastic differential equations that is consistent with Discontinuous Spectral Element Method (DSEM) approximations of Eulerian conservation laws. The method extends the favorable properties of DSEM that include its high-order accuracy, its local and boundary fitted properties and its high performance on parallel platforms for the concurrent Monte-Carlo, semi-Lagrangian and Eulerian solution of a class of time-dependent problems that can be described by coupled Eulerian-Lagrangian formulations. The semi-Lagrangian method seeds particles at Gauss quadrature collocation nodes within a spectral element. The particles are integrated explicitly in time according to a drift velocity and a Wiener increment forcing and form the nodal basis for an advected interpolant. This interpolant is mapped back in a semi-Lagrangian fashion to the Gauss quadrature points through a least squares fit using constraints for element boundary values. Stochastic Monte-Carlo samples are averaged element-wise on the quadrature nodes. The stable explicit time step Wiener increment is sufficiently small to prevent particles from leaving the element's bounds. The semi-Lagrangian method is hence local and parallel and does not have the grid complexity, and parallelization challenges of the commonly used Lagrangian particle solvers in particle-mesh methods for solution of Eulerian-Lagrangian formulations. Formal proof is presented that the semi-Lagrangian algorithm evolves the solution according to the Eulerian Fokker-Planck equation. Numerical tests in one and two dimensions for drift-diffusion problems show that the method converges exponentially for constant and non-constant advection and diffusion velocities.

The effect of background and presentation mode on transparent layer constancy
Creators: name: Falkenberg, Charlotte
name: Faul, Franz
Publisher: name: F1000Research
Year: 2015

description: We investigated the degree of transparent layer constancy when matching filter colors across different illuminations. Previous studies reported varying degrees of constancy and it was suggested that constancy is not influenced by whether or not the subjects have a transparency impression. We systematically examined the role of viewing context and phenomenal impression on constancy performance. We compared normal filter presentation that leads to phenomenal transparency with a flipped filter version that violates geometric transparency cues and appears opaque (X- vs T-junctions). Two different background structures were used and we also varied the presentation mode (static vs motion, monocular vs stereo, simultaneous vs alternating display of test and standard). We found that the geometric cues had the largest effect on transparent layer constancy: It was significantly higher with X-junctions than with T-junctions. Alternating presentation of standard and test enhanced constancy throughout. The effects of motion, stereo and background structure were smaller and more complex: While in the case of X-junctions constancy was enhanced when the objects were moving or presented in a more structured background pattern it was reduced with T-junctions. Together, this suggests that the more vivid the impression of a transparent layer is the higher the degree of constancy.

description: It has been shown that attention is coupled with movement relevant locations and/or targets (Baldauf, Wolf & Deubel, 2006). Previous research has also suggested that when executing autonomous movements, such as driving, attending to movements can reduce accuracy, suggesting instead that attending to external locations of feedback increases movement accuracy (Prinz, 1997). We aimed to examine whether attention was allocated to feedback locations in goal-directed pointing. We conducted three experiments. General Design: Eight digital 8s were presented in a circular array around a central fixation cross. The fixation changed to an arrow indicating the movement target. Before the movement all targets changed to 2s and 5s with one target changing to a 3 or E, reverting back to digital 8s. Participants were required to report if they seen a 3 or E on each trial (measure of attentional allocation). After executing their movement they were provided with feedback two positions anti-clockwise as either a green digital 8 for a correct movement or red for incorrect. In experiment 1 participants were able to see their hand, although maintaining central fixation. Participants demonstrated attentional allocation to the movement and feedback targets. In experiment 2 a mirror task design was used meaning participants could not see their hand. Attentional allocation increased across all locations however locations irrelevant to movement or feedback also received attention. In experiment 3 the arrow cue pointed to the feedback target instead of the movement target. Attentional allocation remained consistent at the movement location. Our studies provide evidence for a coupling of attention and movement, independent of an arrow cue and when feedback is provided elsewhere.

description: Emerging diseases are acknowledged as a growing threat to wildlife, with the continued identification of pathogenic and potentially pathogenic viruses in avian species resulting from ongoing advances in molecular diagnostic techniques. Parvoviruses under the genus Chaphamaparvovirus (subfamily Hamaparvovirinae) are highly divergent. The detection and characterisation of parvoviruses in psittacine birds is limited. This study reports a novel parvovirus, tentatively named psittaciform chaphamaparvovirus 3 (PsChV-3) under the genus Chaphamaparvovirus, identified in an Australian free-ranging little corella (Cacatua sanguinea). The PsChV-3 genome is 4277 bp in length and encompasses four predicted open-reading frames, including two major genes, a nonstructural replicase gene (NS1), and a structural capsid gene (VP1). The NS1 and VP1 genes showed the closest amino acid identities of 78.8% and 69.7%, respectively, with a recently sequenced psittaciform chaphamaparvovirus 2 from Australian Neophema species grass parrots. In addition, the presence of two complete novel beak and feather disease (BFDV) genomes, 1993 and 1868 nt in length, respectively, were detected from the same bird. Both these BFDV genomes contained two bidirectional ORFs encoding the putative Rep and Cap proteins. Phylogenetic analysis showed that the sequenced novel BFDV genomes clustered in a distinct subclade with other BFDVs isolated from Australian cockatoos. This study contributes to the characterisation chaphamaparvoviruses and BFDV in Australian parrots and supports the need for ongoing monitoring and molecular studies into the avian virome in native Australian psittacine bird species.
The role of background distortions in material matches of transparent objects

description: It has been proposed that the visual system uses background distortions as a cue to estimate the refractive index of thick transparent objects. We have previously argued that it is theoretically implausible that such estimates can be made and that approximately correct refractive index matches that putatively support this claim can alternatively be explained more parsimoniously by assuming direct matches of image attributes. In the present investigation the subjects had to match the material of two transparent objects, but, in contrast to previous studies, we used different background texture densities for standard and test and manipulated the visibility of the undistorted part of the backgrounds. The results suggest that the subjects simply maximized the similarity of the image patterns inside the object boundaries and thus referred to information that is insufficient to estimate the objects’ refractive indices. Subjects can also take the undistorted part of the background into account if this is suggested by experimental layout or instruction, but they do this in a rather simplistic way that also seems inappropriate to estimate refractive indices of transparent objects. These results provide additional evidence against the assumption that the visual system estimates the refractive index of transparent objects from background distortions.

description: Let $(Ω,\mathcal{B},P)$ be a probability space, $\mathcal{A}\subset\mathcal{B}$ a sub-$σ$-field, and $μ$ a regular conditional distribution for $P$ given $\mathcal{A}$. Necessary and sufficient conditions for $μ(ω)(A)$ to be 0--1, for all $A\in\mathcal{A}$ and $ω\in A_0$, where $A_0\in\mathcal{A}$ and $P(A_0)=1$, are given. Such conditions apply, in particular, when $\mathcal{A}$ is a tail sub-$σ$-field. Let $H(ω)$ denote the $\mathcal{A}$-atom including the point $ω\inΩ$. Necessary and sufficient conditions for $μ(ω)(H(ω))$ to be 0--1, for all $ω\in A_0$, are also given. If $(Ω,\mathcal{B})$ is a standard space, the latter 0--1 law is true for various classically interesting sub-$σ$-fields $\mathcal{A}$, including tail, symmetric, invariant, as well as some sub-$σ$-fields connected with continuous time processes.

description: The gamma-ray emitting galaxy SBS 0846+513 has been classified as a Narrow-Line Seyfert 1 from its spectroscopy, and on that basis it was thought likely to have a small central black hole hosted in a spiral galaxy. But very few of the gamma-ray Narrow-Line Seyfert 1s have high-resolution imaging of their hosts, so it is unknown how those expectations hold up for the gamma-emitting class. We have observed this galaxy in the J-band with the Large Binocular Telescope's LUCI1 camera and the ARGOS adaptive optics system. We estimate its black hole mass to lie between $7.70 \leq \log \frac{\text{M}}{\text{M}_\odot} \leq 8.19$, using the correlation with bulge luminosity, or $7.96 \leq \log \frac{\text{M}}{\text{M}_\odot} \leq 8.16$ using the correlation with Sérsic index, putting its mass at the high end of the Narrow Line Seyfert 1 range. These estimates are independent of the Broad Line Region viewing geometry and avoid underestimates due to looking down the jet axis. Its host shows evidence of a bulge + disc structure, both from two-dimensional modeling and isophote shape, in keeping with the expectations. Mergers and interactions appear to be common among the gamma-ray Narrow-Line Seyfert 1s, and we see some circumstantial evidence for companion galaxies or disturbed features in the host.

description: The first lattice QCD result on the nuclear force (the NN potential) is presented in the quenched level. The standard Wilson gauge action and the standard Wilson quark action are employed on the lattice of the size 16^3\times 24 with the gauge coupling beta=5.7 and the hopping parameter kappa=0.1665. To obtain the NN potential, we adopt a method recently proposed by CP-PACS collaboration to study the pi pi scattering phase shift. It turns out that this method provides the NN potentials which are faithful to those obtained in the analysis of NN scattering data. By identifying the equal-time Bethe-Salpeter wave function with the Schroedinger wave function for the two nucleon system, the NN potential is reconstructed so that the wave function satisfies the time-independent Schroedinger equation. In this report, we restrict ourselves to the J^P=0^+ and I=1 channel, which enables us to pick up unambiguously the ``central'' NN potential V_{central}(r). The resulting potential is seen to posses a clear repulsive core of about 500 MeV at short distance (r < 0.5 fm). Although the attraction in the intermediate and long distance regions is still missing in the present lattice set-up, our method is appeared to be quite promising in reconstructing the NN potential with lattice QCD.

Numerical Study of Molten Metal Melt Pool Behaviour during Conduction-mode Laser Spot Melting

description: Molten metal melt pools are characterised by highly non-linear responses, which are very sensitive to imposed boundary conditions. Temporal and spatial variations in the energy flux distribution are often neglected in numerical simulations of melt pool behaviour. Additionally, thermo-physical properties of materials are commonly changed to achieve agreement between predicted melt-pool shape and experimental post-solidification macrograph. Focusing on laser spot melting in conduction mode, we investigated the influence of dynamically adjusted energy flux distribution and changing thermo-physical material properties on melt pool oscillatory behaviour using both deformable and non-deformable assumptions for the gas-metal interface. Our results demonstrate that adjusting the absorbed energy flux affects the oscillatory fluid flow behaviour in the melt pool and consequently the predicted melt-pool shape and size. We also show that changing the thermophysical material properties artificially or using a non-deformable surface assumption lead to significant differences in melt pool oscillatory behaviour compared to the cases in which these assumptions are not made.
