description: Abstract: "The authors consider antiplane shearing motions of an incompressible visco-plastic solid. The particular constitutive equation employed assumes that the stress tensor has an 'elastic' component and a component which can exhibit hysteresis. The model exhibits both 'kinematic' and 'isotropic' hardening. Our results consist of a set of energy type estimates for the resulting system, LΓéé contractivity estimates for the solution operator, and finally an analysis of the approach of our system to a 'rate independent' model as a distinguished parameter describing our flow rule approaches zero. We also include some computational results for simple piecewise constant data."

description: Vacuum expectation values of the energy-momentum tensor for a conformally coupled scalar field is investigated in de Sitter (dS) spacetime in presence of a curved brane on which the field obeys the Robin boundary condition with coordinate dependent coefficients. To generate the corresponding vacuum densities we use the conformal relation between dS and Rindler spacetimes and the results previously obtained by one of the authors for the Rindler counterpart. The resulting energy-momentum tensor is non-diagonal and induces anisotropic vacuum stresses. The asymptotic behaviour of this tensor is investigated near the dS horizon and the boundary.

description: The temporal covariance between seismic waves measured at two locations on the solar surface is the fundamental observable in time-distance helioseismology. Above the acoustic cut-off frequency ($\sim$5.3~mHz), waves are not trapped in the solar interior and the covariance function can be used to probe the upper atmosphere. We wish to implement appropriate radiative boundary conditions for computing the propagation of high-frequency waves in the solar atmosphere. We consider the radiative boundary conditions recently developed by Barucq et al. (2017) for atmospheres in which sound-speed is constant and density decreases exponentially with radius. We compute the cross-covariance function using a finite element method in spherical geometry and in the frequency domain. The ratio between first- and second-skip amplitudes in the time-distance diagram is used as a diagnostic to compare boundary conditions and to compare with observations. We find that a boundary condition applied 500 km above the photosphere and derived under the approximation of small angles of incidence accurately reproduces the `infinite atmosphere' solution for high-frequency waves. When the radiative boundary condition is applied 2 Mm above the photosphere, we find that the choice of atmospheric model affects the time-distance diagram. In particular, the time-distance diagram exhibits double-ridge structure when using a VAL atmospheric model.

description: The mechanism of the Coulomb breakup reactions of the nuclei with neutron-halo structure is investigated in detail. A time-dependent Schrödinger equation for the halo neutron is numerically solved by treating the Coulomb field of a target as an external field. The momentum distribution and the post-acceleration effect of the final fragments are discussed in a fully quantum mechanical way to clarify the limitation of the intuitive picture based on the classical mechanics. The theory is applied to the Coulomb breakup reaction of $^{11}$Be + $^{208}$Pb. The breakup mechanism is found to be different between the channels of $j^π=\frac{1}{2}^{-}$ and $\frac{3}{2}^{-}$, reflecting the underlying structure of $^{11}$Be. The calculated result reproduces the energy spectrum of the breakup fragments reasonably well, but explains only about a half of the observed longitudinal momentum difference.

description: Based on multi-epoch observations at 15 and 43 GHz with the Very Long Baseline Array (VLBA) we detect significant angular expansions between the two hot spots of 4 Compact Symmetric Objects (CSOs). From these relative motions we derive kinematic ages of between 300 and 1200 years for the radio emission. These ages lend support to the idea that CSOs are produced in a recent phase of activity. These observations also allow us to study the evolution of the hot spots dynamically in individual sources. In all 4 sources the hot spots are separating along the source axis, but in 1031+567 the tip of one hot spot appears to be moving almost orthogonally to the source axis. Jet components, seen in 3 of the 4 sources observed, are found to be moving relativistically outward from the central engines towards the more slowly moving hot spots.

description: Although spatial smoothing of fMRI data can serve multiple purposes, increasing the sensitivity of activation detection is probably its greatest benefit. However, this increased detection power comes with a loss of specificity when non-adaptive smoothing (i.e. the standard in most software packages) is used. Simulation studies and analysis of experimental data was performed using the R packages neuRosim and fmri. In these studies, we systematically investigated the effect of spatial smoothing on the power and number of false positives in two particular cases that are often encountered in fMRI research: (1) Single condition activation detection for regions that differ in size, and (2) multiple condition activation detection for neighbouring regions. Our results demonstrate that adaptive smoothing is superior in both cases because less false positives are introduced by the spatial smoothing process compared to standard Gaussian smoothing or FDR inference of unsmoothed data.

Noise properties of two single electron transistors coupled by a nanomechanical resonator

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We analyze the noise properties of two single electron transistors (SETs) coupled via a shared voltage gate consisting of a nanomechanical resonator. Working in the regime where the resonator can be treated as a classical system, we find that the SETs act on the resonator like two independent heat baths. The coupling to the resonator generates positive correlations in the currents flowing through each of the SETs as well as between the two currents. In the regime where the dynamics of the resonator is dominated by the back-action of the SETs, these positive correlations can lead to parametrically large enhancements of the low frequency current noise. These noise properties can be understood in terms of the effects on the SET currents of fluctuations in the state of a resonator in thermal equilibrium which persist for times of order the resonator damping time.

Eastern Venezuelan Foreland Basin

description: The Morichito Subbasin is a southwest-northeast oriented depocenter that is located in the Eastern Venezuelan Foreland Basin (EVFB). The Morichito Subbasin covers an approximate area of 1,000 km² between the Serranía del Interior fold and thrust belt and the Pirital High. This basin was formed during the Neogene as the result of complex transpressional interactions between the Caribbean and South-American plates. Previous studies have tried to address the tectonostratigraphic significance of the Morichito Subbasin but about 1,800 km² recently acquired 3D seismic volumes allowed us to expand our understanding of this subbasin. The relevance of the Morichito Subbasin lies in the fact that it provides a valuable stratigraphic record that can be used to unveil the timing of the main deformational events that took place in this portion of the EVFB. This work presents the tectonostratigraphic evolution of the Morichito Subbasin by defining four sequences (Units I to IV). These units were defined based on the integration of well logs and biostratigraphic information with geomorphological interpretations that were performed using 3D seismic data. Unit I (E. Miocene to M. Miocene) was deposited in shallow marine environments (the Carapita Formation) and its areal coverage extends to the south, beyond the boundaries of the Morichito Subbasin suggesting that Unit I pre-dates the formation of the Pirital High. Unit II (M. Miocene) is composed of alluvial fan deposits (the Morichito Formation) that were derived from the Serranía del Interior fold and thrust belt; pinch-out relationships against the Pirital High indicates that Unit II was contemporaneous with the Pirital thrusting event. Units III (L. Miocene to E. Pliocene) and IV (E. Pliocene to Recent) are composed of shallow marine and fluvial deposits (Las Piedras and Mesa Formations). These two units represent the final phases of basin infilling when tectonic activity and subsidence were at lower rates

description: Despite frequent utilization, little data are currently available documenting outcomes associated with antipsychotic polypharmacy. The purpose of this study was to evaluate antipsychotic polypharmacy pharmacoepidemiology and identify potential predictors of utilization. The CQI+™ database (Mental Health Outcomes Inc.) provides outcomes data for patient and treatment-focused variables for all age/diagnostic groups in multiple psychiatric settings. From this database, adults (18-65 years) diagnosed with schizophrenia-related or schizoaffective disorder prescribed one or more antipsychotics upon discharge between January 1998 and May 2004 were eligible for inclusion. Demographics and other characteristics of patients receiving antipsychotic monotherapy or polypharmacy were compared using the Pearson chi-square test and student’s t-test. All tests were two-tailed with significance defined as an alpha < 0.05. Binary logistic regression was performed to identify significant predictors of patients receiving antipsychotic polypharmacy at discharge with complete covariate data. A stepwise forward conditional method was utilized with a covariate entry criterion of an alpha < 0.05. A total of 3,003 patients received antipsychotic monotherapy (n=2185) or polypharmacy (n=818) upon discharge. Significant associations were observed between antipsychotic polypharmacy use and race/ethnicity (p=0.001), comorbid substance abuse history (p<0.001), mental health facility regional location (p<0.001), and payment method (p<0.001). Those receiving polypharmacy had higher mean number of hospitalization days (39.44±72.55 vs. 21.63±50.15, p<0.001), higher mean admission Behavior and Symptom Identification Scale (BASIS-32) Psychosis subscale scores (1.10±0.04 vs. 1.05±0.03, p=0.040), and lower mean admission BASIS-32 Depression/Anxiety subscale scores (1.79±1.15 vs. 1.89±1.11, p=0.041). Two, three, and four antipsychotic regimens were prescribed in 24.1%, 2.9%, and 0.27% of patients receiving an antipsychotic, respectively. A typical antipsychotic and olanzapine or risperidone were most frequently prescribed antipsychotic combinations. Significant predictors of antipsychotic polypharmacy included: charity/contract funding (p=0.001), northeastern or western United States location (p<0.001), positive substance abuse history (p=0.037), a higher number of previous hospitalizations (p=0.004) and higher admission BASIS-32 Psychosis subscale scores (p<0.001). Despite the lack of evidence supporting its use, antipsychotic polypharmacy is frequently prescribed. Potential predictors of antipsychotic polypharmacy include substance abuse history, payment method, service region, and illness severity. These data provide important information regarding the phenomenology of antipsychotic polypharmacy

description: We propose and investigate a method of error detection and noise correction for bosonic linear networks using a method of unitary averaging. The proposed error averaging does not rely on ancillary photons or control and feed-forward correction circuits, remaining entirely passive in its operation. We construct a general mathematical framework for this technique then give a series of proof of principle examples including numerical analysis. Two methods for the construction of averaging are then compared to determine the most effective manner of implementation and probe the related error thresholds. Finally we discuss some of the potential uses of this scheme.

Depositional element morphology and architecture of the Atoka interval, Fort Worth Basin, TX, U.S.A.

description: The Atoka Group (Lower-Middle Pennsylvanian) of the Fort Worth Basin (FWB) forms a significant (~2-3 Tcf), and as yet underexploited, domestic gas resource that is often seen as a secondary target as operators make their way to the deeper Barnett Shale. Although thousands of wells penetrate the Atoka in the FWB, the origin and character of this unit are still debated. The influence of deeper Ellenburger karsting on depositional morphology and element character has also been insufficiently addressed. Current depositional model interpretations vary from wave-dominated, to river-dominated, to fan deltas, comprising various braided, meandering, and mixed-load stream systems. An understanding of the facies in the Atoka and their spatial distribution can be enhanced by utilizing the most effective tool in describing each level of resolution (seismic/low, well log/medium, core/high) and producing methods of correlation that accurately define the geometries that exist. A 3-D survey covering 68 km² of the FWB has been integrated with data from 226 wells and core from 3 wells for detailed mapping of the Atoka. In seismic, the Atoka is represented by a ~200-ms interval showing geometric relationships of lapout (onlap, offlap, toplap, downlap, and truncation), which suggest the existence of imageable geomorphic features. Both seismic and well log mapping show that the Atoka can be subdivided into 12 parasequences that stack to form: (a) a lower, regressive; (b) a middle, transgressive; and (c) an upper, highstand parasequence set. Core analysis reveals that eight main facies exist in the Atoka, which suggest the interval comprises a series of coarse-grained, fluvio-deltaic and shallow marine deposits. Criteria are outlined for defining channel dimensions using point bar measurements from well logs, and a detailed quantitative analysis of the variability of these dimensions in cross-section and plan-view was undertaken. Point-bar analyses indicate that channel widths range from 34 to 456 m, given the variability in both local and regional accommodation space created during deposition. A review and comparison of modern and ancient analogs to Atoka sediments support the interpretation of a river-dominated delta system. The argument is reinforced by observations from facies components identified in core, gamma-ray-log expressions, and the distant location of the study relative to highland sources. Previous fan- and wave-dominated delta interpretations are therefore discounted and do not apply to the study area

description: Interstellar travel requires propulsion systems beyond present possibilities and scientists search for new technologies and breakthrough concepts in physics. Frederick E. Alzofon came up with an alternative idea on the origin of the gravitational field. He claimed that the gravitational force arises from the interaction of subatomic particles and that the gravitational force between the particles of a system decreases during a process of retrograding from an ordered system into a disordered system. To proof his assumption, Alzofon used pulsed dynamic nuclear polarization to create such an order of particles within a test object and claims to have measured distinct changes in weight. This paper describes an experiment to investigate Alzofon's assumptions with the use of NMR spectroscopy for nuclear spin polarization. It could be shown that with certain measurement parameters, an apparent change in weight was indeed measured, but finally this turned out to be a temperature effect.

description: I combine previous data from Mesozoic outcrops in the Guajira Peninsula of northern Colombia with new regional gravity, bathymetric, and seismic interpretations to demonstrate the existence of a 280-km-long, western extension of the Great Arc of the Caribbean (GAC) along the continental margin of Colombia. Seismic data reveal a 80 to 100 km-wide domal-shape basement high lacking seismic reflectivity and mappable for 1800 km from the Aves Ridge to the study area in offshore Colombia. The western extension of the GAC in Colombia and western Venezuela is buried by 700 to 3000 m of continental margin sediments because it collided earlier (Cretaceous-early Paleogene collision) than its subaerially exposed eastern part on the Leeward Antilles Ridge (late Paleogene-Neogene collision). Compilation of radiometric age dates and geologic information from the entire GAC shows that arc magmatism ocurred from 128 to 74 Ma with a general pattern of younging from west to east. I mapped six Upper Eocene to Recent marine seismic sequences that overlie the domal basement high of the GAC using 2400 km of seismic reflection data and 12 wells. Three deformation events affecting the sequences include: 1) late Eocene rifting, in an east-west direction produced half-grabens in the northern part of the area; 2) Oligocene transtension, in the southern part of the area expressed by right-lateral Oligocene strike-slip faulting and extensional basin formation; 2) early - middle Miocene transtension; and 3) late Miocene - early Pliocene Andean uplift and clastic infilling of offshore basins

Due to the practically exact agreement of the energy of the $Ne$ resonance and of the $p+p+{}^{16}{O}$ threshold, the transition probability is found to be considerably enhanced. This indicates the possibility of nuclear fusion in rotationally excited $H_2O$ molecules in the state $1^-$.

description: The resistivity of a superconductor in its normal state plays a critical role in determining its superconducting ground state. However, measuring the resistivity of a material under high pressure has long presented a significant technical challenge due to pressure-induced changes in the crystallographic directions, especially for samples with anisotropic layered structures like high-Tc superconductors and other intriguing quantum materials. Here, we are the first to propose a novel and effective method for determining high-pressure resistivity, which relies on the ambient-pressure resistivity, initial sample sizes, lattice parameters, high-pressure resistance, and lattice parameters measured from the same sample. Its validity has been confirmed through our investigations of pressurized copper-oxide superconductors, which demonstrates that this method provides new possibilities for researchers conducting high-pressure studies related to resistivity of these materials.

description: The existence of neutron star mergers has been supported since the discovery of the binary pulsar and the observation of its orbital energy loss, consistent with General Relativity. They are considered nucleosynthesis sites of the rapid neutron-capture process (r-process), which is responsible for creating approximately half of all heavy elements beyond Fe and is the only source of elements beyond Pb and Bi. Detailed nucleosynthesis calculations based on the decompression of neutron star matter are consistent with solar r-process abundances of heavy nuclei. Neutron star mergers have also been identified with short-duration γ-ray bursts via their IR afterglow. The high neutron densities in ejected matter permit a violent r-process, leading to fission cycling of the heaviest nuclei in regions far from (nuclear) stability. Uncertainties in several nuclear properties affect the abundance distributions. The modeling of astrophysical events also depends on the hydrodynamic treatment, the occurrence of a neutrino wind after the merger and before the possible emergence of a black hole, and the properties of black hole accretion disks. We discuss the effect of nuclear and modeling uncertainties and conclude that binary compact mergers are probably a (or the) dominant site of the production of r-process nuclei in our Galaxy.

description: The paper is concerned with the construction of a stochastic model for the spatially discretized time-dependent Schrödinger equation. The model is based on a particle system with a Markov jump evolution. The particles are characterized by a sign (plus or minus), a position (discrete grid) and a type (real or imaginary). The jumps are determined by the creation of offsprings. The main result is the construction of a family of complex-valued random variables such that their expected values coincide with the solution of the Schrödinger equation.

description: In this dissertation, I propose that public diplomacy on social networking sites (SNS), or SNS diplomacy, features both asymmetrical national influences and the public’s participation. I also theorize that diplomatic and public discourses co-shape national images and influences in SNS diplomatic spheres. It is a popular expectation that social media facilitates nations’ exertion of their influences abroad and potentially disrupts the global hierarchy of national influence. This expectation, in my view, lacks a critical or public participatory perspective. I therefore examine two sets of power dynamics in SNS diplomacy, which are: 1) those between foreign nations and 2) those between foreign nations and the public. To do so, I compare the diplomatic-public discursive interactions centered around four nations – Japan, Korea, the US, and the UK – on Chinese social platform Weibo over a 11-year period (2010-2020). For this social media critical discourse study, I employ topic modeling and discourse analysis to analyze over 150,000 Weibo posts and comments with both efficiency and contextual sensitivity. The analysis illustrates the four nations’ reproduction of the pre-existing international hierarchy of influence, in which the Western nations enjoy the dominant status, through their respective social media practices. Japan and Korea focus on gaining global recognition for their commodifiable experiences, whereas the US and the UK aim to fortify their leadership in world politics and global development. However, nations are not the only constructor of national images and influences in SNS diplomatic spheres. My analysis also suggests that, driven by their interest- or value-based rationality, the Chinese public can enhance or interrupt foreign national influence exertion through their everyday online deliberation. I conclude that digital disruption has empowered the public to reshape foreign national influences, but it has not empowered nations to change the international hierarchy of influence. Contrary to the conventional focus on how national images are constructed by nations, I argue that the significance of SNS diplomacy lies in how national images are co-constructed with nations by the public on social media.

description: We are concerned with the acoustic scattering by an extended obstacle surrounded by point-like obstacles. The extended obstacle is supposed to be rigid while the point-like obstacles are modeled by point perturbations of the exterior Laplacian. In the first part, we consider the forward problem. Following two equivalent approaches (the Foldy formal method and the Krein resolvent method), we show that the scattered field is a sum of two contributions: one is due to the diffusion by the extended obstacle and the other arises from the linear combination of the interactions between the point-like obstacles and the interaction between the point-like obstacles with the extended one. In the second part, we deal with the inverse problem. It consists in reconstructing both the extended and point-like scatterers from the corresponding far-field pattern. To solve this problem, we describe and justify the factorization method of Kirsch. Using this method, we provide several numerical results and discuss the multiple scattering effect concerning both the interactions between the point-like obstacles and between these obstacles and the extended one.
Annihilating Cold Dark Matter

description: Structure formation with cold dark matter (CDM) predicts halos with a central density cusp, which are observationally disfavored. If CDM particles have an annihilation cross section sigma*v ~ 10**(-29) (m/GeV) cm**2, then annihilations will soften the cusps. We discuss plausible scenarios for avoiding the early Universe annihilation catastrophe that could result from such a large cross section. The predicted scaling of core density with halo mass depends upon the velocity dependence of sigma*v, and s-wave annihilation leads to a core density nearly independent of halo mass, which seems consistent with observations.

description: We consider a basket or spread option on based on a multi-dimensional local volatility model. Bayer and Laurence [Comm. Pure. Appl. Math., to appear] derived highly accurate analytic formulas for prices and implied volatilities of such options when the options are not at the money. We now extend these results to the ATM case. Moreover, we also derive similar formulas for the local volatility of the basket.

description: In this paper we consider a elastic vector-valued Allen--Cahn MPCC (Mathematical Programs with Complementarity Constraints) problem. We use a regularization approach to get the optimality system for the subproblems. By passing to the limit in the optimality conditions for the regularized subproblems, we derive certain generalized first-order necessary optimality conditions for the original problem.
Flavor-Violating ALPs, Electron g-2, and the Electron-Ion Collider

description: We revisit the possibility that light axion-like particles (ALPs) with lepton flavor violating couplings could give significant contributions to the electron's anomalous magnetic moment $g_e-2$. Unlike flavor diagonal lepton-ALP couplings, which are exclusively axial, lepton flavor violating couplings can have arbitrary chirality. Focusing on the $e$-$τ$ ALP coupling, we find that the size of the contribution to $g_e-2$ depends strongly on the chirality of the coupling. A significant part of the parameter space for which such a coupling can explain experimental anomalies in $g_e-2$ can be probed at the Electron-Ion Collider, which is uniquely sensitive to the chirality of the coupling using the polarization of the electron beam.

description: We derive the multi-fractal scaling of probability distributions of multi-particle configurations for the binary reaction-diffusion system $A+A \to \emptyset$ in $d \leq 2$ and for the ternary system $3A \to \emptyset$ in $d=1$. For the binary reaction we find that the probability $P_{t}(N, ΔV)$ of finding $N$ particles in a fixed volume element $ΔV$ at time $t$ decays in the limit of large time as $(\frac{\ln t}{t})^{N}(\ln t)^{-\frac{N(N-1)}{2}}$ for $d=2$ and $t^{-Nd/2}t^{-\frac{N(N-1)ε}{4}+\mathcal{O}(\ep^2)}$ for $d<2$. Here $\ep=2-d$. For the ternary reaction in one dimension we find that $P_{t}(N,ΔV) \sim (\frac{\ln t}{t})^{N/2}(\ln t)^{-\frac{N(N-1)(N-2)}{6}}$. The principal tool of our study is the dynamical renormalization group. We compare predictions of $\ep$-expansions for $P_{t}(N,ΔV)$ for binary reaction in one dimension against exact known results. We conclude that the $\ep$-corrections of order two and higher are absent in the above answer for $P_{t}(N, ΔV)$ for $N=1,2,3,4$. Furthermore we conjecture the absence of $\ep^2$-corrections for all values of $N$.

Properties of the solutions of delocalised coagulation and inception problems with outflow boundaries

description: Well posedness is established for a family of equations modelling particle populations undergoing delocalised coagulation, advection, inflow and outflow in a externally specified velocity field. Very general particle types are allowed while the spatial domain is a bounded region of $d$-dimensional space for which every point lies on exactly one streamline associated with the velocity field. The problem is formulated as a semi-linear ODE in the Banach space of bounded measures on particle position and type space. A local Lipschitz property is established in total variation norm for the propagators (generalised semi-groups) associated with the problem and used to construct a Picard iteration that establishes local existence and global uniqueness for any initial condition. The unique weak solution is shown further to be a differentiable or at least bounded variation strong solution under smoothness assumptions on the parameters of the coagulation interaction. In the case of one spatial dimension strong differentiability is established even for coagulation parameters with a particular bounded variation structure in space. This one dimensional extension establishes the convergence of the simulation processes studied in [Patterson, textitStoch. Anal. Appl. 31, 2013] to a unique and differentiable limit.
Tetrahedral mesh improvement using moving mesh smoothing and lazy searching flips

description: In this paper we combine two new smoothing and flipping techniques. The moving mesh smoothing is based on the integration of an ordinary differential coming from a given functional. The lazy flip technique is a reversible edge removal algorithm to automatically search flips for local quality improvement. On itself, these strategies already provide good mesh improvement, but their combination achieves astonishing results which have not been reported so far. Provided numerical examples show that we can obtain final tetrahedral meshes with dihedral angles between 40 and 123 degrees. We compare the new method with other publicly available mesh improving codes.
Anomalous diffusion in fast cellular flows at intermediate time scales

description: It is well known that on long time scales the behaviour of tracer particles diffusing in a cellular flow is effectively that of a Brownian motion. This paper studies the behaviour on “intermediate” time scales before diffusion sets in. Various heuristics suggest that an anomalous diffusive behaviour should be observed. We prove that the variance on intermediate time scales grows like O(t√). Hence, on these time scales the effective behaviour can not be purely diffusive, and is consistent with an anomalous diffusive behaviour.
