Subjects: Environmental Science

description: Nowadays , we use fossil fuels fuels for electricity, heat for our homes and fuel for vehicles. We are using them fasterthan they are created. Finally, they are going to end. Today, there is an urgent need to find another source to fossil fuelssince fossil fuels are vanishing . we need to discover another source of energy. This article leads us to noticethat Press Mud, a waste from sugar cane, can be utilized for the production of bio gas. The sugar industry produces ahuge amount of waste that is organic and nutrients rich in nature. Sugar cane Press Mud, have a high potential for theproduction of renewable energy through the anaerobic digestion process. In order to obtain bio gas from the mud, pressmud is anaerobically fermented in an anaerobic digester for 3 to 4 hours at 35 to 40 ˚C .As India Stands second largestproducer of sugarcane, this can play important role in India

description: Using high-resolution spin-resolved photoemission spectroscopy, we observed a thermal spin depolarization to which all spin-polarized electrons contribute. Furthermore we observed a distinct minority spin state near the Fermi level and a corresponding depolarization that seldom contributes to demagnetization. The origin of this depolarization has been identified as the many-body effect characteristics of half-metallic ferromagnets. Our investigation opens an experimental field of itinerant ferromagnetic physics focusing on phenomena with sub-meV energy scale.

description: We apply a new anticommuting path integral technique to clarify the fermionic structure of the 2D Ising model with quenched site dilution. In the $N$-replica scheme, the model is explicitly reformulated as a theory of interacting fermions on a lattice. An unusual feature is that the leading term of interaction in the exact lattice theory is of order $2N$ in fermions, where $N$ is the number of replicas. The continuum-limit approximation near $T_c $ for weak dilution produces, however, an effective four-fermion interaction. In particular, this implies the doubled-logarithmic singularity in the specific heat near $T_c$ for weak site dilution. The exact value of the initial slope is also obtained. Keywords: Ising model, site disorder, anticommuting Grassmann variables

description: Precise microwave measurements of sample conductivity, dielectric, and magnetic properties are routinely performed with cavity perturbation measurements. These methods require the accurate determination of quality factor and resonant frequency of microwave resonators. Seven different methods to determine the resonant frequency and quality factor from complex transmission coefficient data are discussed and compared to find which is most accurate and precise when tested using identical data. We find that the nonlinear least-squares fit to the phase vs. frequency is the most accurate and precise when the signal-to-noise ratio is greater than 65. For noisier data, the nonlinear least squares fit to a Lorentzian curve is more accurate and precise. The results are general and can be applied to the analysis of many kinds of resonant phenomena.

Non-singular black holes interiors need physics beyond the standard model

description: The composition as well as the very existence of the interior of a Schwarzschild black hole (BH) remains at the forefront of open problems in fundamental physics. To address this issue, we turn to Hawking's "principle of ignorance", which says that, for an observer with limited information, all descriptions that are consistent with known physics are equally valid. We compare three different observers who view the BH from the outside and agree on the external Schwarzschild geometry. First, the modernist, who accepts the classical BH as the final state of gravitational collapse, the singularity theorems that underlie this premise and the central singularity that the theorems predict. The modernist is willing to describe matter in terms of quantum fields in curved space but insists on (semi)classical gravity. Second is the skeptic, who wishes to evade any singular behavior by finding a loophole to the singularity theorems within the realm of classical general relativity (GR). The third is a postmodernist who similarly wants to circumvent the singularity theorems but is willing to invoke exotic quantum physics in the gravitational and/or matter sector to do so. The postmodern view suggests that the uncertainty principle can stabilize a classically singular BH in a similar manner to the stabilization of the classically unstable hydrogen atom: Strong quantum effects in the matter and gravitational sectors resolve the would-be singularity over horizon-sized length scales. The postmodern picture then requires a significant departure from (semi)classical gravity, as well as some exotic matter beyond the standard model of particle physics (SM). We find that only the postmodern framework is consistent with what is known so far about BH physics and conclude that a valid description of the BH interior needs matter beyond the SM and gravitational physics beyond (semi)classical GR.

description: We derive analytical expressions for the Young's modulus and the Poisson's ratio of the graphene nanoribbon, in which free edges are warped by the compressive edge stress. Our analytical formulas explicitly illustrate the reduction of the Young's modulus by the warped free edges, leading to the obvious width dependence for the Young's modulus of the graphene nanoribbon. The Poisson's ratio is also reduced by the warped free edges, and negative Poisson's ratio can be achieved in the graphene nanoribbon with an ultra-narrow width. These results are comparable with previous theoretical works.
Continuous matter fields in Regge calculus

Year: 2000
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We find that the continuous matter fields are ill-defined in Regge calculus in the physical 4D theory since the corresponding effective action has infinite terms unremovable by the UV renormalisation procedure. These terms are connected with the singular nature of the curvature distribution in Regge calculus, namely, with the presence in d>2 dimensions of the (d-3)-dimensional simplices where the (d-2)-dimensional ones carrying different conical singularities are meeting. Possible resolution of this difficulty is discretisation of matter fields in Regge background.

description: We demonstrate both theoretically and experimentally that the harmonics from abruptly auto-focusing ring-Airy beams present a surprising property, they preserve the phase distribution of the fundamental beam. Consequently, this "phase memory" inherits to the harmonics the abrupt autofocusing behavior, while, under certain conditions, their foci coincide in space with the one of the fundamental. Experiments agree well with our theoretical estimates and detailed numerical calculations. Our findings open the way for the use of such beams and their harmonics in strong field science.

description: We present a theory for the single particle excitations and Fermi surface of the Kondo lattice. Thereby we construct an effective Hamiltonian describing the creation and propagation of single particle-like charge fluctuations on an `RVB-background' of local singlets. The theory may be viewed as a `Fermionic version' of linear spin wave theory and is of comparable simplicity, so that the calculations for the strong-coupling limit can be performed analytically. We calculate the single particle spectral function for the standard Kondo lattice as well as for several extended versions: with a Coulomb repulsion between conduction and f-electrons, Coulomb repulsion between conduction electrons, and a `breathing' f-orbital. In all cases we study the evolution of the spectrum in going from the Kondo insulator to the Heavy electron metal. We compare our results to exact diagonalization of small clusters and find remarkable agreement in nearly all cases studied. In the metallic case the f-electrons participate in the Fermi surface volume even if they are replaced by localized Kondo-spins and the number of bands, their dispersion and spectral character, and the nontrivial (i.e. non-rigid band-like) doping dependence including a pronounced transfer of spectral weight are reproduced by the theory.

We apply the method to lambda-repressor and compare with site directed mutagenesis experiments. The formation of native structure and the free energy profile along the folding route are shown to be well described by the capillarity approximation but with some fine structure due to local folding topology.

We show how the shape of the spectrum is related to the valence electronic structure and the Cu-O network but also that other atoms can play a role.

description: Scalability remains a challenge in multi-agent reinforcement learning and is currently under active research. A framework named mean-field reinforcement learning (MFRL) could alleviate the scalability problem by employing the Mean Field Theory to turn a many-agent problem into a two-agent problem. However, this framework lacks the ability to identify essential interactions under nonstationary environments. Causality contains relatively invariant mechanisms behind interactions, though environments are nonstationary. Therefore, we propose an algorithm called causal mean-field Q-learning (CMFQ) to address the scalability problem. CMFQ is ever more robust toward the change of the number of agents though inheriting the compressed representation of MFRL's action-state space. Firstly, we model the causality behind the decision-making process of MFRL into a structural causal model (SCM). Then the essential degree of each interaction is quantified via intervening on the SCM. Furthermore, we design the causality-aware compact representation for behavioral information of agents as the weighted sum of all behavioral information according to their causal effects. We test CMFQ in a mixed cooperative-competitive game and a cooperative game. The result shows that our method has excellent scalability performance in both training in environments containing a large number of agents and testing in environments containing much more agents.

description: Limitations of the toxicity characteristic leaching procedure (TCLP) for simulating pollutant leaching from wastes disposed of in full-scale landfills are well understood in the waste management profession; the TCLP solution has a lower pH and greater organic acid content than typical landfill leachate. The TCLP serves its intended regulatory objective, however, as long as a conservative estimate of leaching is provided. Here, we examine TCLP’s ability to represent worst-case leaching conditions for monofilled municipal solid waste incineration (MSWI) ash. A critical examination of TCLP’s applicability to MSWI ash is especially relevant, as ash management at MSWI facilities often centers on passing TCLP, regardless of environmental risk posed by the ash or its recyclability. Multiple batch leaching tests were conducted on different MSWI ash streams: mixed ash, fly ash, and different size fractions of bottom ash. Batch-test results were compared with leachate simulating MSWI ash monofills. The TCLP did not consistently provide the most conservative estimate of leaching, supporting the need to consider alternative methodologies in future regulatory development. Implications: This paper analyzes the existing hazardous waste regulatory testing requirement for municipal solid waste incinerator (MSWI) ash management to evaluate whether the TCLP serves its intended purpose in providing the most conservative estimate of landfilled MSWI ash. The results will serve as guidance and motivation for policy makers and the regulatory community to reevaluate the TCLP’s application for characterizing MSWI ash leaching in certain disposal scenarios and could promote consideration of alternative testing procedures based upon results of this study. This study serves to promote representative and accurate quantification of leaching risk from MSWI ash.

description: We study the dynamics associated with the extension of turbulent convective motions from a convection zone (CZ) into a stable region (RZ) that lies below the latter. For that purpose, we have run a series of three-dimensional direct numerical simulations solving the Navier-Stokes equations under the Boussinesq approximation in a spherical shell geometry. We observe that the overshooting of the turbulent motions into the stably stratified region depends on three different parameters: the relative stability of the RZ, the transition width between the two, and the intensity of the turbulence. In the cases studied, these motions manage to partially alter the thermal stratification and induce thermal mixing, but not so efficiently as to extend the nominal CZ further down into the stable region. We find that the kinetic energy below the convection zone can be modeled by a half-Gaussian profile whose amplitude and width can be predicted a priori for all of our simulations. We examine different dynamical lengthscales related to the depth of the extension of the motions into the RZ, and we find that they all scale remarkably well with a lengthscale that stems from a simple energetic argument. We discuss the implications of our findings for 1D stellar evolution calculations.

Numerical simulations show that this theory gives an improved approximation for the coverage compare to the previous linear recursion relations approach. Furthermore, these two approximations provide useful upper and lower bounds for a number of characteristics including the coverage, growth velocity, and the roughness exponent.

We focus on the problem of charge ordering and the charge phase diagram. We show that the main interactions are the long-range Coulomb interaction and a dipolar short-range interaction generated by the short-range antiferromagnetic fluctuations. We find four different phases depending on the strength of the dipolar interaction and the density of holes: Wigner crystal, diagonal stripes, horizontal-vertical stripes (loops) and a glassy-clumped phase. We discuss the effect of temperature, disorder and lattice effects on these phases.

description: In a shallow near-infrared survey of the dwarf Irregular galaxy, NGC 3109, near the periphery of the Local Group, we have found eight Mira variables, seven of which appear to be oxygen-rich (O-Miras). The periods range from about 430 days to almost 1500 days. Because of our relatively bright limiting magnitude, only 45 of the more than 400 known carbon stars were measured, but none was found to be a large amplitude variable. One of the Miras may be an unrecognised C star. Five of the O-Miras are probably hot-bottom burning stars considering that they are brighter than expected from the period--luminosity relation of Miras and that, by comparison with theoretical evolutionary tracks, they appear to have masses >~4 Msun. A census of very long period (P>1000 days) Miras in the Galaxy and Magellanic Clouds is presented and discussed together with the newly discovered long period, but relatively blue, variables in NGC 3109. New $JHKL$ photometry is presented for three O-rich long period Miras i n the SMC (including a candidate super-AGB star).

description: Using the X-ray data taken with ASCA, a detailed analysis was made of intensity and spectral variations of three ultra-luminous extra-galactic compact X-ray sources (ULXs); IC 342 source 1, M81 X-6, and NGC 1313 source B, all exhibiting X-ray luminosity in the range 10^{39}-1.5x10^{40} erg s^{-1}. As already reported, IC 342 source 1 showed short-term X-ray intensity variability by a factor of 2.0 on a typical time scale of 10 ks. M81 X-6 varied by a factor of 1.6 across seven observations spanning 3 years, while NGC 1313 source B varied by a factor of 2.5 between two observations conducted in 1993 July and 1995 November. The ASCA spectra of these sources, acquired on these occasions, were all described successfully as optically-thick emission from standard accretion disks around black holes. This confirms previous ASCA works which explained ULXs as mass-accreting massive black-hole binaries. In all three sources, the disk color temperature was uncomfortably high at T_{in}=1.0-2.0 keV, and was found to vary in proportion to the square-root of the source flux. The apparent accretion-disk radius is hence inferred to change as inversely proportional to T_{in}. This suggests a significant effect of advection in the accretion disk. However, even taking this effect fully into account, the too high values of T_{in} of ULXs cannot be explained. Further invoking the rapid black-hole rotation may give a solution to this issue.

description: It is a honor to write a contribution on this memorial for Sandro Massidda. For both of us, at different stages of our life, Sandro was first and foremost a friend. We both admired his humble, playful and profound approach to life and physics. In this contribution we describe the route which permitted to meet a long-standing challenge in solid state physics, i.e. room temperature superconductivity. In less than 20 years the Tc of conventional superconductors, which in the last century had been widely believed to be limited to 25 K, was raised from 40 K in MgB2 to 265 K in LaH10. This discovery was enabled by the development and application of computational methods for superconductors, a field in which Sandro Massidda played a major role.

Random sequential adsorption is an idealization for surface deposition where the time scale of particle relaxation is much longer than the time scale of deposition. Particles are represented as extended objects which are adsorbed to a continuum surface or lattice sites. Once landed on the surface, the particles stick to the surface. We review in some details various methods of computing the coverage theta(t) and present some of the recent and new results in random sequential adsorption.

On the Faddeev-Popov determinant in Regge calculus
Creators: name: Khatsymovsky, V. M.
Publisher: name: arXiv
Year: 2000
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The functional integral measure in the 4D Regge calculus normalised w.r.t. the DeWitt supermetric on the space of metrics is considered. The Faddeev-Popov factor in the measure is shown according to the previous author's work on the continuous fields in Regge calculus to be generally ill-defined due to the conical singularities. Possible resolution of this problem is discretisation of the gravity ghost (gauge) field by, e.g., confining ourselves to the affine transformations of the affine frames in the simplices. This results in the singularity of the functional measure in the vicinity of the flat background, where part of the physical degrees of freedom connected with linklengths become gauge ones.

description: We consider the low-energy collective excitations at finite temperature of Bose--Einstein condensed gases (and liquids as well). A most general model-independent effective Lagrangian is written down according to a prescription obtained from the breakdown of the global symmetry U(1). To show how the theory predicts easily, we derive the momentum and temperature dependence of the damping of excitations by means of power counting as an example.

description: The change of the Josephson supercurrent density of a weakly-connected granular superconductor in response to externally applied arbitrary thermal gradient dT/dx (nonlinear Seebeck effect) is considered within a model of 3D Josephson junction arrays. For dT/dx>(dT/dx)_c, where (dT/dx)_c is estimated to be of the order of 10^4 K/m for YBCO ceramics with an average grain's size of 10 microns, the weak-links-dominated thermopower S (Seebeck coefficient) is predicted to become strongly dT/dx-dependent.

A `superoutburst' in XTE J1118+480
Creators: name: Kuulkers, Erik
Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I propose that the properties of the two outbursts observed in the X-ray transient XTE J1118+480 in 2000 are akin to superoutbursts of SU UMa stars. In these systems a `normal' outburst immediately precedes a 5-10 times longer (`super')outburst. The optical light curve of the outbursts of XTE J1118+480 is remarkably similar to that seen in some SU UMa stars, such as UV Per and T Leo, where the precursor outburst is distinct from the superoutburst, but the time scales are a factor of ~15 different. The first outburst of XTE J1118+480 was relatively short (~1 month) while the second outburst was ~5 times longer. During the second outburst superhumps were seen, a feature characteristic for superoutbursts. The gap of about a month between the two outbursts is longer in X-rays with respect to the optical, a feature not previously recognized for X-ray transients. Also in SU UMa stars the precursor outburst becomes more distinct at shorter wavelengths. Finally, I show that the time of appearance of the superhumps in XTE J1118+480 is consistent with the expected superhump growth time, if the superhump mechanism was triggered during the first outburst. I conclude that the similarity in outburst behaviour in the two types of systems provides further support that a common mechanism is at work to start the long (`super')outbursts.

description: We present a detailed description of the electromagnetic filter for the PTOLEMY project to directly detect the Cosmic Neutrino Background (CNB). Starting with an initial estimate for the orbital magnetic moment, the higher-order drift process of ExB is configured to balance the gradient-B drift motion of the electron in such a way as to guide the trajectory into the standing voltage potential along the mid-plane of the filter. As a function of drift distance along the length of the filter, the filter zooms in with exponentially increasing precision on the transverse velocity component of the electron kinetic energy. This yields a linear dimension for the total filter length that is exceptionally compact compared to previous techniques for electromagnetic filtering. The parallel velocity component of the electron kinetic energy oscillates in an electrostatic harmonic trap as the electron drifts along the length of the filter. An analysis of the phase-space volume conservation validates the expected behavior of the filter from the adiabatic invariance of the orbital magnetic moment and energy conservation following Liouville's theorem for Hamiltonian systems.
Sharp selective scattering of red, green and blue light achieved via gain material's loss compensation

description: For a transparent projection screen based on metallic nanoparticle's localized surface plasmon resonance (LSPR), in the ideal case the metallic nanoparticles dispersed in a transparent matrix only selectively scatter red, green and blue light and transmit the visible light of other colours. However, metal's optical loss and size effect at nanoscale degenerate the desired performance by broadening the resonance peak width and increasing the absorption ratio. In this work, it is shown that the problem can be solved by introducing gain material. Numerical simulations are performed on nanostructures based on silver (Ag), gold (Au) or aluminium (Al) with or without gain material, to examine the effect of gain material and to search for suitable structures for sharp selective scattering of red, green and blue light. And it is found that introducing gain material greatly improves performance of the structures based on Ag or Au except the structures based on Al. The most suitable structures for sharp selective scattering of red, green and blue light are respectively found to be the core-shell structures of silica@Au, silica@Ag and Ag@silica, all with gain material.
The interaction of surface acoustic waves with an array of quantum wires
Creators: name: Rokni, Michal
name: Levinson, Y.
Publisher: name: arXiv
Year: 1999
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: We describe the interaction of surface acoustic waves with electrons in an array of quantum wires, patterned out of a two dimensional electron gas. Two specific geometries are considered, in which the surface acoustic wave travels parallel, or perpendicular to the wires. Although we assume the electron wave functions in different wires do not overlap, the screening of the phonon potential by the electrons in the wire array is a collective phenomenon. It is shown that the surface acoustic wave absorption cannot be described via the ac conductivity in the usual manner. We derive an integral equation for the dielectric function of the electrons in the quantum wire system, and solve it in the narrow wire approximation. Using the dielectric function we find the absorption and the change in velocity of the surface acoustic waves.

description: We study the massive scalar field of a charged particle held at rest in conical thin-shell spacetimes with one or two asymptotic regions. Resonant and stable scalar Green's functions are characterized in terms of the coupling of the field to the trace of the extrinsic curvature jump at the shell. Stable coupling values, within the safety domain of the configuration parameters, are used to analyze the self-force of static point charges.

title: The Consequences of Vicarious Intergroup Exclusion
Creators: name: Lantos, Dorottya
Publisher: name: Goldsmiths, University of London
Year: 2020

description: Intergroup violence and conflict have devastating consequences for individuals and societies alike. Across five experimental studies (N = 1,870) conducted cross-culturally using a multimethod approach integrating behavioural and neuroscientific research methods, this thesis tested the consequences of vicarious intergroup exclusion, exclusion that concerns ingroup members, but that does not directly target the individual. The results indicate that the experimental manipulation of vicarious intergroup exclusion is experienced on the personal level, increasing perceived personal exclusion. At least under some conditions, it impairs mood (Studies 1-4), increases intergroup hostility (Studies 1, 4) and aggression (Study 3, 4), and threatens fundamental psychological needs (Study 1b). The increased aggression following the ingroup’s observed exclusion may target not only members of the excluding outgroup, but members of ‘innocent’ outgroups as well (Study 3). The results further indicate that group status and power do not influence the effects of exclusion on mood, hostility, and aggression (Study 1b). Antagonistic, but not secure ingroup positivity was related to a greater increase in hostility following vicarious intergroup exclusion (Study 3). Vicarious intergroup exclusion affected hostility (Studies 1, 3, 4) and aggression (Studies 1b, 4) indirectly, via impaired mood, but not via threatened needs (Study 1b). Based on the underlying role of mood impairment, we tested interventions aiming to reduce the negative affect, intergroup hostility, and aggression related to vicarious intergroup exclusion by fortifying emotion regulation (Studies 2, 4). However, the interventions were unsuccessful in achieving these aims. Not all studies replicated all findings, so we summarized the main results observed throughout the thesis in meta-analyses. The meta-analytic summaries indicate that the intergroup settings used to create the experimental manipulation of vicarious intergroup exclusion (e.g., existing vs. minimal groups) influenced its effects. These findings, their implications, and future research directions are discussed in detail.
