description: The positions of images produced by the gravitational lensing of background sources provide unique insight in to galaxy-lens mass distribution. However, even quad images of extended sources are not able to fully characterize the central regions of the host galaxy. Most previous work has focused either on the radial density profile of the lenses or localized substructure clumps. Here, we concentrate on the azimuthal mass asymmetries near the image circle. The motivation for considering such mass inhomogeneities is that the transition between the central stellar dominated region and the outer dark matter dominated region, though well represented by a power law density profile, is unlikely to be featureless, and encodes information about the dynamical state and assembly history of galaxies. It also happens to roughly coincide with the Einstein radius. We ask if galaxies that have mass asymmetries beyond ellipticity can be modeled with simpler lenses, i.e., can complex mass distributions masquerade as simple elliptical+shear lenses? Our preliminary study indicates that for galaxies with elliptical stellar and dark matter distributions, but with no mass asymmetry, and an extended source filling the diamond caustic, an elliptical+shear lens model can reproduce the images well, thereby hiding the potential complexity of the actual mass distribution. For galaxies with non-zero mass asymmetry, the answer depends on the size and brightness distribution of the source, and its location within the diamond caustic. In roughly half of the cases we considered the mass asymmetries can easily evade detection.

Quantum Computation Based on Retarded and Advanced Propagation
Creators: name: Castagnoli, Giuseppe
Publisher: name: arXiv
Year: 1997
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Computation is currently seen as a forward propagator that evolves (retards) a completely defined initial vector into a corresponding final vector. Initial and final vectors map the (logical) input and output of a reversible Boolean network respectively, whereas forward propagation maps a one-way propagation of logical implication, from input to output. Conversely, hard NP-complete problems are characterized by a two-way propagation of logical implication from input to output and vice versa, given that both are partly defined from the beginning. Logical implication can be propagated forward and backward in a computation by constructing the gate array corresponding to the entire reversible Boolean network and constraining output bits as well as input bits. The possibility of modeling the physical process undergone by such a network by using a retarded and advanced in time propagation scheme is investigated.

Year: 2018
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We systematically investigate the properties of three-dimensional dipolar binary Bose mixture at low temperatures. A set of coupled self-consistent equations of motion are derived for the two condensates. In the homogeneous case, useful analytical formulas for the condensate depletion, the anomalous density, the ground-state energy, and the equation of state are obtained. The theory is extended to the inhomogeneous case and the importance of the inhomogeneity is highlighted. Our results open up a new avenue for studying dipolar mixture droplets. Impacts of the dipole-dipole interaction on the stability, density profiles, and the size of the self-bound droplet are deeply discussed. The finite-temperature behavior of such a state is also examined.

Prompt atmospheric neutrinos and muons: NLO vs LO QCD predictions

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

description: We compare the leading and next-to-leading order QCD predictions for the flux of atmospheric muons and neutrinos from decays of charmed particles. We find that the full NLO lepton fluxes can be approximated to within 10% by the Born--level fluxes multiplied by an overall factor of 2.2-2.4, which depends slightly on the PDF. This supports the approach in Thunman, Ingelman, Gondolo (1996). We also find that their very low lepton fluxes are due to the mild slope they used for the gluon distribution function at small momentum fractions, and that substantially larger lepton fluxes result when the slope of the gluon distribution function at small momentum fractions is larger.

Perturbative expansions for the fidelities and spatially correlated dissipation of quantum bits

description: We construct generally applicable short-time perturbative expansions for some fidelities, such as the input-output fidelity, the entanglement fidelity, and the average fidelity. Successive terms of these expansions yield characteristic times for the damping of the fidelities involving successive powers of the Hamiltonian. The second-order results, which represent the damping rates of the fidelities, are extensively discussed. As an interesting application of these expansions, we use them to study the spatially-correlated dissipation of quantum bits. Spatial correlations in the dissipation are described by a correlation function. Explicit conditions are derived for independent decoherence and for collective decoherence.

description: Intel Software Guard Extensions (SGX) is a promising hardware-based technology for protecting sensitive computations from potentially compromised system software. However, recent research has shown that SGX is vulnerable to branch-shadowing -- a side channel attack that leaks the fine-grained (branch granularity) control flow of an enclave (SGX protected code), potentially revealing sensitive data to the attacker. The previously-proposed defense mechanism, called Zigzagger, attempted to hide the control flow, but has been shown to be ineffective if the attacker can single-step through the enclave using the recent SGX-Step framework. Taking into account these stronger attacker capabilities, we propose a new defense against branch-shadowing, based on control flow randomization. Our scheme is inspired by Zigzagger, but provides quantifiable security guarantees with respect to a tunable security parameter. Specifically, we eliminate conditional branches and hide the targets of unconditional branches using a combination of compile-time modifications and run-time code randomization. We evaluated the performance of our approach by measuring the run-time overhead of ten benchmark programs of SGX-Nbench in SGX environment.

description: We have calculated complete spectra of the staggered Dirac operator on the lattice in quenched SU(3) gauge theory for β= 5.4 and various lattice sizes. The microscopic spectral density, the distribution of the smallest eigenvalue, and the two-point spectral correlation function are analyzed. We find the expected agreement of the lattice data with universal predictions of the chiral unitary ensemble of random matrix theory up to a certain energy scale, the Thouless energy. The deviations from the universal predictions are determined using the disconnected scalar susceptibility. We find that the Thouless energy scales with the lattice size as expected from theoretical arguments making use of the Gell-Mann--Oakes--Renner relation.

description: Die brandenburgische Museumslandschaft ist dezentral strukturiert und geprägt durch kleine bis mittelgroße Museen mit kleinen Teams und knappen Ressourcen. Diese Ausgangslage ist für die nachhaltige Etablierung digital gestützter Arbeitsabläufe alles andere als optimal. Mit themenbezogenen Verbundprojekten unterstützt der Museumsverband Brandenburg daher seit mehreren Jahren die Museen auf ihrem Weg in die digitalisierte Arbeitswelt. Seit 2012 konnten im Zuge von neun Verbundprojekten über 6.000 Objekte aus 54 brandenburgischen Museen digitalisiert werden. Gut die Hälfte der Digitalisate wurde auf museum-digital veröffentlicht. Insgesamt präsentieren 62 brandenburgische Museen über 8.300 Objekte auf der Plattform. Zu 96 Prozent sind die Objektdigitalisate mit einer Creative-Commons-Lizenz versehen. Mit den auf museum-digital gezeigten Objektdigitalisaten sowie den objektbeschreibenden Metadaten werden in bisher nie da gewesener Weise materielle Zeugnisse der brandenburgischen Natur-, Kunst- und Kulturgeschichte öffentlich sichtbar und zugänglich. Die freien Kulturdaten ermöglichen der regionalen, nationalen und internationalen Forschung neue, vor allem auf die materielle Kultur fokussierte Zugänge. Darüber hinaus wird die wissenschaftliche Vernetzung sowohl unter den Museen als auch zwischen Museen und Universitäten bzw. anderen forschenden Institutionen gestärkt. Schwerpunkte auf museum-digital:brandenburg bilden bisher rund 1.500 Fotografien zu lokalen und regionalen Zeitgeschichte, über 1.000 Objekte zur preußischen Adelskultur, mehr als 1.300 Zeugnisse der Handwerks- und Industriegeschichte sowie über 700 Grafiken zur Architektur- und Baugeschichte Brandenburgs.

description: Recently experimental techniques, such as magnetic force microscopy (MFM), have enabled the magnetic state of individual sub-micron particles to be resolved. Motivated by these experimental developments, we use Monte Carlo simulations of two-dimensional kinetic Ising ferromagnets to study the magnetic relaxation in a negative applied field of a grain with an initial magnetization $m_0 = +1$. The magnetostatic dipole-dipole interactions are treated to lowest order by adding to the Hamiltonian a term proportional to the square of the magnetization. We use droplet theory to predict the functional forms for some quantities observed by MFM, such as the probability that the magnetization is positive. Our simulations are in excellent agreement with droplet-theoretical predictions. The qualitative agreement between experiments and our simulations of switching in individual single-domain ferromagnets indicates that the switching mechanism in such particles may involve local nucleation and subsequent growth of droplets of the stable phase.

title: Evolutionary Techniques for De Novo Protein Conformation Ensemble Generation
Creators: name: (:Unkn) Unknown
Publisher: name: George Mason University
Year: 2021

description: The conformations in which a protein molecule arranges its amino-acid chain are primary determinants of its ability to interact with other molecules in the living cell. Discovering the functionally-relevant conformations of a protein is crucial to elucidating its functional repertoire and even further our understanding of diseases driven by mutations that affect the ability of a protein to assume specific conformations. Discovering the possibly diverse set of biologically-relevant conformations of a protein from knowledge of its amino-acid sequence alone remains an outstanding challenge. While progress has been made in this direction, most notably by AlphaFold2, in discovering what is often referred to as a native structure, methods based on machine learning, including deep learning, are limited in their ability to see the entirety of the conformation space of a protein. While obtaining one conformation is sufficient for some proteins, many others are involved in many cellular reactions in the cell, and harness their ability to assume different conformations to achieve functional plasticity. Nowhere is the ability of proteins to assume different conformations more visible in the public eye than nowadays; we are all familiar with images that show the spike protein in the SARS-CoV2 virus switching between an open and a closed conformation to elude our immune system and strike at just the right moment by binding with the ACE receptors in its closed conformation. This dissertation presents a way forward on exploring the conformation space of a given protein molecule, when the only information available is the sequence of amino acids. We refer to this problem as de-novo protein conformation ensemble generation. In this dissertation, we present several novel stochastic optimization algorithms that operate under the umbrella of evolutionary computation. We show that these algorithms are able to balance between the known challenges of exploration and exploitation and capture meaningful representations of the conformation space, despite its size and complexity. In particular, we show that they are able to capture the presence of significantly different functionally-relevant conformations in metamorphic proteins, which we also provide to the community as a benchmark to further advance research on this problem. The work presented in this dissertation represents important groundwork for researchers aiming to improve protein conformation sampling in order to better understand the structural and functional plasticity of protein molecules in all their exquisite complexity.
DFT studies of the role of anion variation in physical properties of Cs2NaTlBr6-xClx (x = 0, 1, 2, 3, 4, 5, and 6) mixed halide double perovskites for optoelectronics

description: Halide-double perovskites have various benefits over lead-based perovskites due to their suitable optical absorption efficiency, higher stability, tunable bandgap, large carrier mobility, easy availability, and low cost. The structural, electrical, optical, and mechanical characteristics of the lead-free halide double perovskites Cs2NaTlBr6-xClx (x = 0, 1, 2, 3, 4, 5, and 6) are investigated by utilizing the first-principles density functional theory (DFT). The structural properties were computed at equilibrium, revealing that the crystals undergo structural phase transitions as the doping concentration varies. However, crystal stability was confirmed through the evaluation of the tolerance factor. The HSE06 functional is used to correct the bandgap underestimation by GGA-PBE. The band edge profile and electron density of states confirm the direct-bandgap semiconducting nature of the compounds. The bandgap increases approximately linearly with Cl incorporation, sharply tuned from 0.80–1.75 eV (GGA-PBE) and 1.78–2.98 eV (HSE06), making them highly suitable for photovoltaic and optoelectronic applications. The effective mass of electron ranges from 0.283m0 to 0.449m0, and the carrier mobility is from 83.913 cm2v-1s-1 to 305.485 cm2v-1s-1, respectively, suggesting excellent charge transport characteristics, essential for high-performance solar cells and photodetectors. The considered NaTL-based double perovskites have strong optical absorption in the visible and UV spectrum, with enhanced conductivity as Cl content increases. Binding energy analysis confirms strong lattice stability, with values decreasing from -3.193 eV (Br-rich) to -3.559 eV (Cl-rich), indicating improved thermodynamic robustness as Cl concentration increases. Mechanical analysis shows the ductile behavior of the considered perovskites, supported by Poisson's ratio and Pugh's modulus. The rising bulk modulus and Debye temperature with Cl incorporation enhance rigidity and thermal stability. These insights advance the anion-engineered design of stable, high-efficiency, lead-free NaTl-based perovskites for next-generation optoelectronic applications.

description: We investigate a large class of supersymmetric SO(10) grand unified theories within the framework of gauge-mediated supersymmetry breaking. We start with the most general messenger sector and imbedd the standard model gauge group into either SU(2)_L X SU(2)_R X U(1)_{B-L} or SU(2)_L X U(1)_{I_{3R}} X U(1)_{B-L}. We find that the conditions of the perturbativity of the gauge couplings and unification at the GUT scale severely restrict the messenger sector and lead to testable phenomenological predictions for the sparticle masses. One of the most notable features of the class of supersymmetric SO(10) grand unified theories introduced here is that among the many possible cases there are only a few consistent models, all of which share an essentially unique mass spectrum.

description: This letter proposes a scheme for transporting nanoparticles immersed in a fluid, relying on quantum vacuum fluctuations. The mechanism lies in the inhomogeneity-induced lateral Casimir force between a nanoparticle and a gradient metasurface, and the relaxation of the conventional Dzyaloshinskiǐ-Lifshitz-Pitaevskiǐ constraint, which allows quantum levitation for a broader class of material configurations. The velocity for a nanosphere levitated above a grating is calculated and can be up to a few microns per minute. The Born approximation gives general expressions for the Casimir energy which reveal size-selective transport. For any given metasurface, a certain particle-metasurface separation exists where the transport velocity peaks, forming a "Casimir passage". The sign and strength of the Casimir interactions can be tuned by the shapes of liquid-air menisci, potentially allowing real-time control of an otherwise passive force, and enabling interesting on-off or directional switching of the transport process.

description: The dynamics of the spin-boson Hamiltonian is considered in the stochastic approximation. The Hamiltonian describes a two-level system coupled to an environment and is widely used in physics, chemistry and the theory of quantum measurement. We demonstrate that the method of the stochastic approximation which is a general method of consideration of dynamics of an arbitrary system interacting with environment is powerful enough to reproduce qualitatively striking results by Leggett at al. found earlier for this model. The result include an exact expression of the dynamics in terms of the spectral density and show an appearance of two most interesting regimes for the system, i.e. pure oscillating and pure damping ones. Correlators describing environment are also computed.

The leading term in this expansion is the valence (quenched) approximation vacuum expectation value. Higher terms give corrections to the valence approximation.

Incorporating a soft ordered phase into an amorphous configuration enhances its uniform plastic deformation under shear

description: Amorphous materials of homogeneous structures usually suffer from nonuniform deformation under shear, which can develop into shear localization and eventually destructive shear band. One approach to tackle this issue is to introduce an inhomogeneous structure containing more than one phase, which can reduce the local nonuniform shear deformation and hinder its percolation throughout the system. Using thermostated molecular dynamics (MD) simulations, we compare the deformation behavior between a homogeneous amorphous mixture of bidisperse disc particles, interacting via an n-6 Lennard-Jones potential of tunable softness, with an inhomogeneous one containing an evenly-distributed ordered phase. We change the population ratio of large to small particles to create a homogeneous or an inhomogeneous mixture, where the softness of a chosen phase can be manually adjusted by specifying n of the interparticle potential. Results of applying extensive quasistatic shear on the prepared mixtures reveal that the inhomogeneous amorphous mixture containing a soft ordered phase overall deforms more uniformly than the homogeneous one, which indicates that both the structure inhomogeneity and the inter-phase softness variance play important roles in enhancing the uniformity of the plastic deformation under shear.

description: Ion-beam sputtering has been used to prepare Fe/Si multilayers on a variety of substrates and over a wide range of temperatures. Small-angle x-ray diffraction and transmission electron microscopy experiments show that the layers are heavily intermixed although a composition gradient is maintained. When the spacer layer is an amorphous iron silicide, the magnetic properties of the multilayers are similar to those of bulk Fe. When the spacer layer is a crystalline silicide with the B2 or DO$_3$ structure, the multilayers show antiferromagnetic interlayer coupling like that observed in ferromagnet/paramagnet multilayers such as Fe/Cr and Co/Cu. Depending on the substrate type and the growth temperature, the multilayers grow in either the (011) or (001) texture. The occurrence of the antiferromagnetic interlayer coupling is dependent on the crystallinity of the iron and iron silicide layers, but does not seem to be strongly affected by the perfection of the layering or the orientation of the film. Since the B2- and DO$_3$-structure Fe$\rm _x$Si$\rm _{1-x}$ compounds are known to be metallic, antiferromagnetic interlayer coupling in Fe/Si multilayers probably originates from the same quantum-well and Fermi surface effects as in Fe/Cr and Co/Cu multilayers.

description: A systematic method for simulating small-scale quantum circuits by use of linear optical devices is presented. It relies on the representation of several quantum bits by a single photon, and on the implementation of universal quantum gates using simple optical components (beam splitters, phase shifters, etc.). This suggests that the optical realization of small quantum networks is reasonable given the present technology in quantum optics, and could be a useful technique for testing simple quantum algorithms or error-correction schemes. The optical circuit for quantum teleportation is presented as an illustration.

Footprint of spatial noncommutativity in resonant detectors of gravitational wave

description: The present day gravitational wave (GW) detectors strive to detect the length variation $δL = h L$, which, owing to the smallness of the metric perturbation $\sim h$, is an extremely small length $\mathcal{O} \sim 10^{-18} - 10^{-21}$ meter. The recently proposed noncommutative structure of space has a characteristic length-scale $\sqrtθ$ which has an estimated upper-bound in similar length-scale range. We therefore propose that GW data can be used as an effective probe of noncommutative structure of space and demonstrate how spatial noncommutativity modifies the responding frequency of the resonant mass detectors of GW and also the corresponding probabilities of GW induced transitions that the phonon modes of the resonant mass detectors undergo. In this paper we present the complete perturbative calculation involving both time-independent and time-dependent perturbation terms in the Hamiltonian.

title: A Goal Activation Account of Confidence Judgments
Creators: name: (:Unkn) Unknown
Publisher: name: George Mason University
Year: 2020

description: Current theories and models of confidence need to be improved to provide a simpler and broader explanation for the relationship between confidence and memory. For example, current theories of confidence posit dozens of features of memory that inform a confidence judgment, making predictions about how confidence changes with novel manipulations difficult. In addition, current models of confidence make robust predictions for tasks with discrete trials but do not specify how a confidence judgment is formed for more complex tasks. In this dissertation I demonstrate that confidence may not be based on a large number of diverse memory features, but rather a more unitary construct, goal activation as defined by Memory for Goals (MFG). MFG is an activation-based model written in the ACT-R cognitive architecture. I begin by investigating how confidence changes in procedural tasks. Procedural tasks already have a strong theoretical back-ground rooted in goal activation and provide the opportunity to investigate how confidence changes in a task over time. For Study 1, I demonstrate the existence of confidence carryover which is a novel finding that current models of confidence do not make predictions about. For Study 2, I formalize confidence carryover mathematically with two different procedural tasks. For Study 3, I show that the predicted outcomes of two competing models of confidence judgments can be formed using subtle memory manipulations. The results of Study 3 add a strategic component that is not addressed by any model of confidence judgments. The results of all three studies suggest that goal activation as seen in MFG is the likely source people use when forming confidence judgments.
Asymptotic Scaling and Infrared Behavior of the Gluon Propagator

description: The Landau gauge gluon propagator for the pure gauge theory is evaluated on a 32^3x64 lattice with a physical volume of (3.35^3x6.7)fm^4. Comparison with two smaller lattices at different lattice spacings allows an assessment of finite volume and finite lattice spacing errors. Cuts on the data are imposed to minimize these errors. Scaling of the gluon propagator is verified between beta=6.0 and beta=6.2. The tensor structure is evaluated and found to be in good agreement with the Landau gauge form, except at very small momentum values, where some small finite volume errors persist. A number of functional forms for the momentum dependence of the propagator are investigated. The form D(q^2)=D_ir+D_uv, where D_ir(q^2) ~ (q^2+M^2)^-ηand D_uv is an infrared regulated one-loop asymptotic form, is found to provide an adequate description of the data over the entire momentum region studied - thereby bridging the gap between the infrared confinement region and the ultraviolet asymptotic region. The best estimate for the exponent ηis 3.2(+0.1/-0.2)(+0.2/-0.3), where the first set of errors represents the uncertainty associated with varying the fitting range, while the second set of errors reflects the variation arising from different choices of infrared regulator in D_uv. Fixing the form of D_uv, we find that the mass parameter M is (1020+/-100)MeV.

description: Previous studies proved the pro-angiogenic effect of Crocetin, a natural carotenoid dicarboxylic acid, in both in vivo and in vitro models. However, the exact mechanism of Crocetin action has not completely been elucidated yet. The current experiment was designed to find the activity of PI3K-Akt-eNOS axis after the treatment of endothelial cells with Crocetin in vitro. Human Umbilical Vein Endothelial Cells (HUVECs) were incubated with various concentrations of Crocetin (1, 5, 25, 50, and 100 µM) over a period of 72 h. Crocetin significantly increased HUVECs viability after 72 h as compared with the control group. We also found that Crocetin promoted the formation of the capillary-like structure compared to the control (p<0.05). Moreover, an improved migration rate and increased MMP-9 activity were observed in HUVECs that received 50 µM Crocetin (p<0.05). Crocetin enhanced the uptake of Ac-LDL which is correlated with increased lipid metabolism. Based on the data from the current experiment, protein level of VEGFR-1, -2 and p-Akt/Akt, p-eNOS/eNOS ratios were increased 72 h after the treatment of HUVECs with Crocetin (p<0.05). In contrast, the transcription level of VEGF was reduced in Crocetin-treated cells. These data demonstrated that Crocetin promotes HUVECs angiogenesis potential by the modulation of VEGF signaling pathway and increased cell viability. The PI3K/Akt/eNOS axis is required for a Crocetin-associated activity in endothelial cells.

Corrected Proximity-Force Approximation for Lateral Casimir Forces

description: The widely-adopted proximity-force approximation (PFA) to estimate normal Casimir forces is known to be asymptotically exact at vanishing separations. In this letter, we propose a correction to the PFA, which is sufficiently accurate in predicting displacement-induced lateral Casimir forces between a sphere and a grating, for separation-to-radius ratio up to 0.5, far beyond the limit within which the application of PFA is previously restricted. Our result allows convenient estimation of Casimir interactions and thus shall be useful in relevant experimental and engineering Casimir applications. We also study the PFA for gradient gratings, and we find that the inhomogeneity-induced lateral Casimir force is beyond the corrected PFA.
