description: Recently, the discovery of superconductivity in Ruddlesden-Popper (RP) $\mathrm{La_4Ni_3O_{10}}$ under pressure has further expanded the realm of nickelate-based superconductor family. In this paper, we performed a first-principle study of $\mathrm{La_4Ni_3O_{10}}$ for both $P2_1/a$ phase at ambient pressure and $I4/mmm$ phase at high pressure, with $U$=0, 3.5\ eV. Our results confirmed the characteristic upward shift of Ni-$d_{z^2}$ bonding band under pressure. Moreover, our analysis of electronic spectrum and orbital occupancy unveil the dynamic mechanism of electronic reconstructions under pressure, embedded in a critical dual effect. Based on our results, we further proposed a trilayer two-orbital model by performing Wannier downfolding on Ni-$e_g$ orbitals. Our model reveals four Fermi surface sheets with $α,β,β^\prime,γ$ pockets, bearing resemblance to that of bilayer $\mathrm{La_3Ni_2O_7}$. According to the model, our calculated spin susceptibility under random phase approximation shows that $d_{x^2-y^2}$ orbital is also important for the magnetic fluctuation in RP series. Finally, a high energy sixteen-orbital model with direct $dp,pp$ hoppings is proposed, which implies that $\mathrm{La_4Ni_3O_{10}}$ also lies in charge-transfer picture within Zaanen-Sawatzky-Allen scheme. Our exposition of electronic reconstructions and multi-orbital models shed light on theoretical electronic correlation study and experimental exploration of lower pressure superconductor in RP series.

Decaying Cold Dark Matter Model and Small-Scale Power
Creators: name: Cen, Renyue
Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The canonical cosmological constant dominated cold dark matter model (LCDM) may possess too much power on small scales at z=0, manifested as central over-concentration of dark matter and over-abundance of dwarf galaxies. We suggest an alternative model, LDCDM, where one half of the cold dark matter particles decay into relativistic particles by z=0. The model successfully lowers the concentration of dark matter in dwarf galaxies as well as in large galaxies like our own at low redshift, while simultaneously retaining the virtues of the LCDM model. The model solves the problem of over-production of small dwarf galaxies in the LCDM not by removing them but by identifying them with failed, "dark" galaxies, where star-formation is quenched due to dark matter evaporation and consequent halo expansion. A dramatic difference between the LDCDM model and other proposed variants of the LCDM model is that the small-scale power at high redshift (z>2) in the LDCDM model is enhanced compared to the LCDM model. A COBE-and-cluster normalized LDCDM model can be constructed with the following parameters: H0=60km/sec/Mpc, lambda0=0.60, Omega_{0,CDM}=0.234, Omega_{0,b}=0.044, n=1.0, and sigma8=1.06. A clean test of this model can be made by measuring the evolution of gas fraction in clusters. The prediction is that the gas fraction should decrease with redshift and is smaller by 31% at z=1 than at z=0. X-ray and Sunyaev-Zel'dovich effect observations should provide such a test.

description: The traditional model of karst and cave formation is that of carbonic acid limestone dissolution, where biologically-produced CO₂ in meteoric water reacts with and dissolves limestone. However, an alternative model has been proposed for several karst sysems where sulfide is abundant, known as sulfuric acid speleogenesis (SAS). Here, acid produced by chemoautotrophic sulfur-oxidizing bacteria (SOB) corrodes limestone while producing dissolved calcium and sulfate. Little is known about the rate of limestone dissolution due to SOB activity, or the nature of the microbe-limestone attachment and interaction. The field site for this study is Lower Kane Cave, WY, an active SAS-formed cave where rapid steam H₂S oxidation is associated with sulfur-oxidizing microbial mats. In this study, the rate of limestone dissolution due to microbial oxidation of reduced sulfur compounds was investigated using laboratory and field microcosms. Laboratory chemostat chamber experiments were designed to mimic the cave environment with and without SOB (native Kane Cave bacteria and Paracoccus versutus), and using different energy sources (thiosulfate, sulfide, and elemental sulfur stored in bacterial filaments). Limestone dissolution rates of abiotic chemostat experiments from this study are comparable to those in previous literature. However, dissolution rates from the experiments with bacteria are 3-4 times faster than the abiotic control rates, a result which is consistent across duplicate experiments and between experiments using different types of SOB. This rate increase represents a complex chemical system influenced by the bacteria on the mineral surface. SEM images confirm that the limestone chips both in the cave and in the biotic chemostat chambers are uniformly covered in biofilm, and that the mineral surface beneath the biofilm is much more etched and corroded than the surface of limestone chips dissolving without bacteria. The results from the lab experiments and the cave microcosms suggest that a biofilm on limestone chips will physically and chemically separate the mineral surface from the bulk solution. Because the bacteria are generating acid directly on the mineral surface, a microenvironment develops beneath the biofilm with low-pH and low saturation state with respect to calcite. The neutrophilic sulfur oxidizing bacteria found in the cave and used in the experiments benefit from attachment to limestone (high buffering capacity), and create a microenvironment that triggers limestone corrosion at a rate several times faster than the abiotic rate.

description: Throughout the past century, the Louisiana coastline has been deteriorating at an alarming rate. Fault induced subsidence has been suggested to be one of the likely drivers of this land loss. I directly addressed the control of faulting on Quaternary delta subsidence using subsurface architectural data. I carried out a systematic process for evaluating fault movement on individual faults in the subsurface by using an industry grade 3-D seismic survey to evaluate the interaction of complex fault patterns and shallow substrate (< 1s or 1,000m). Using amplitude data, as well as a coherency algorithm, horizons and faults were mapped in ~1400km² of data in southeastern Louisiana. Measurements of fault displacement were obtained by determining time offset of synchronous horizons. Down-to-the-basin and counter-regional growth faulting was observed. Both styles of faulting are associated with movement of Jurassic-age salt deposits and display measurable offset at depths as shallow as ~.450s (roughly 380m). Fault displacements increase roughly linearly with burial depth. The displacement data together with well-log data provide a tentative Quaternary rate for the normal faulting of 0.1mm · yr⁻¹ to 1mm · yr⁻¹. I have assessed the possible control of subsurface faulting on surface topography using co-registered maps of fault traces and orthophoto quadrangles. This analysis has revealed a number of instances where faulting affects modern surface morphology. Often, the up-thrown sides of growth faults are capped by marshland, whereas the downthrown blocks are drowned by ~.7m of surface water (Snedden et al., 2007). Further, the influence of faulting extends to the modern planform of the lower Mississippi River, as data indicate that growth faults control the position of a major bend near the river's outlet.

description: In the real world, many elds have highly skewed class distributions and features that vary dramatically in terms of their classification and runtime performance. With a huge volume of data on the web, such fields typically require machine learning (ML) techniques with low latency and high performance. Anti-phishing is one of those fields, which requires a very low False Positive Rate (FP), a reasonably high True Positive Rate (TP) and a fast response time. In those great number of areas including anti-phishing, however, almost all existing ML-based approaches simply focused on designing features, and building a monolithic model using them all at once. A fast response time is of paramount importance to the user experience in a live scenario, and naively extracting values for all features upfront is often an overkill. In our previous work, we proposed a number of anti-phishing approaches that either extend existing URL blacklists in a probabilistic fashion or enhance feature based anti-phishing methods with novel features, and in this thesis, we build on our previous experience with anti-phishing and propose a feature-type-aware cascaded learning framework for the a variety of domains with skewed class distribution and features with various classification and runtime performance in an effort to achieve a good balance between the three desiderata of TP, FP and latency. By utilizing lightweight features in early stages of the cascade and postponing prohibitive ones to later stages, our approach achieves a superior runtime performance in general, and can be further improved via parallelization in the distributed computing environment. Moreover, our approach is scalable with more features, and can be optimized in favor of FP or TP based on the speci c domains. In the context of anti-phishing, our cascaded approach achieves 557% reduction in runtime on average over traditional single-stage models, with a low FP of 065% and a TP of 8334%, and thus provides a fast and reliable solution for live detection scenarios.

description: Based on some important properties of $dS$ space, we present a Beltrami model ${\cal B}_Λ$ that may shed light on the observable puzzle of $dS$ space and the paradox between the special relativity principle and cosmological principle. In ${\cal B}_Λ$, there are inertial-type coordinates and inertial-type observers. Thus, the classical observables can be defined for test particles and light signals. In addition, by choosing the definition of simultaneity the Beltrami metric is transformed to the Robertson-Walker-like metric. It is of positive spatial curvature of order $Λ$. This is more or less indicated already by the CMB power spectrum from WMAP and should be further confirmed by its data in large scale.

description: In this series of papers we aim to provide a mathematically comprehensive framework to the Hamiltonian pictures of quantum field theory in curved spacetimes. Our final goal is to study the kinematics and the dynamics of the theory from the point of differential geometry in infinite dimensions. In this second part we use the tools of Gaussian analysis in infinite dimensional spaces introduced in the first part to describe rigorously the procedures of geometric quantization in the space of Cauchy data of a scalar theory. This leads us to discuss and establish relations between different pictures of QFT. We also apply these tools to describe the geometrization of the space of pure states of quantum field theory as a Khäler manifold. We use this to derive an evolution equation that preserves the geometric structure and avoids norm losses in the evolution. This leads us to a modification of the Schrödinger equation via a quantum connection that we discuss and exemplify in a simple case.

description: The accurate and efficient simulation of bi-variate population balance systems is nowadays a great challenge since the domain spanned by the external and internal coordinates is five-dimensional. This report considers direct discretizations of this equation in tensor-product domains. In this situation, finite difference methods can be applied. The studied model includes the transport of dissolved potassium dihydrogen phosphate (KDP) and of energy (temperature) in a laminar flow field as well as the nucleation and growth of KDP particles. Two discretizations of the coupled model will be considered which differ only in the discretization of the population balance equation: a first order monotone upwind scheme and a third order essentially non-oscillatory (ENO) scheme. The Dirac term on the right-hand side of this equation is discretized with a finite volume method. The numerical results show that much different results are obtained even in the class of direct discretizations.

description: Microbial communities play a key role in biological wastewater treatment processes. Activated sludge settling characteristics, for example, are affected by microbial community composition, varying by changes in operating conditions and influent characteristics of wastewater treatment plants (WWTPs). Timely assessment and prediction of changes in microbial composition leading to settling problems, such as filamentous bulking (FB), can prevent operational challenges, reductions in treatment efficiency, and adverse environmental impacts. This study presents an innovative computer vision-based approach to assess activated sludge-settling characteristics based on the morphological properties of flocs and filaments in microscopy images. Implementing the transfer learning of deep convolutional neural network (CNN) models, this approach aims to overcome the limitations of existing quantitative image analysis techniques. The offline microscopy image dataset was collected over two years, with weekly sampling at a full-scale industrial WWTP in Belgium. Multiple data augmentation techniques were employed to enhance the generalizability of the CNN models. Various CNN architectures, including Inception v3, ResNet18, ResNet152, ConvNeXt-nano, and ConvNeXt-S, were tested to evaluate their performance in predicting sludge settling characteristics. The sludge volume index was used as the final prediction variable, but the method can easily be adjusted to predict any other settling metric of choice. The results showed that the suggested CNN-based approach provides less labour-intensive, objective, and consistent assessments, while transfer learning notably minimises the training phase, resulting in a generalizable system that can be employed in real-time applications.

description: A full calculation of lepton-pair angular characteristics is carried out for $e^+e^-$ pairs created in $p + Be$ and $Ca + Ca$ collisions from 1.0 to 2.1 GeV/A. It is demonstrated that the dilepton decay anisotropy depends sensitively on the different sources and may be used for their disentangling. Due to the dominance of the $η$-and $Δ$-Dalitz decays and only a small anisotropy coefficient for $π^+π^-$ annihilation, the expected anisotropy coefficients show a decrease with invariant mass of the dilepton pair and change only moderately when comparing $p + Be$ and $Ca + Ca$ reactions at the same bombarding energy.

description: Abstract: "We present a method of enhanced convergence for the approximation of analytic functions. This method introduces conformal transformations in the approximation problems in order to help extract the values of a given analytic function from its Taylor expansion. We show that conformal transformations can extend the radius of convergence of a power series far into infinity, enhance substantially its convergence rates inside the circle of convergence, and can produce a rather dramatic improvement in the conditioning of Pade╠ü approximation. This improvement, which we discuss theoretically for Stieltjes type functions, is most notorious in cases of very poorly conditioned Pade╠ü problems. In some instances, an application of enhanced convergence leads to results which are many orders of magnitude more accurate than those obtained by clasical approximants."

description: We present a new method for remeshing surfaces that respect the intrinsic anisotropy of the surfaces. In particular, we use the normal informations of the surfaces, and embed the surfaces into a higher dimensional space (here we use 6d). This allow us to form an isotropic mesh optimization problem in this embedded space. Starting from an initial mesh of a surface, we optimize the mesh by improving the mesh quality measured in the embedded space. The mesh is optimized by combining common local modifications operations, i.e., edge flip, edge contraction, vertex smoothing, and vertex insertion. All operations are applied directly on the 3d surface mesh. This method results a curvature-adapted mesh of the surface. This method can be easily adapted to mesh multi-patches surfaces, i.e., containing corner singularities and sharp features. We present examples of remeshed surfaces from implicit functions and CAD models.

description: Deep Neural Networks have impressive classification performance, but this comes at the expense of significant computational resources at inference time. Autonomous Underwater Vehicles use low-power embedded systems for sonar image perception, and cannot execute large neural networks in real-time. We propose the use of max-pooling aggressively, and we demonstrate it with a Fire-based module and a new Tiny module that includes max-pooling in each module. By stacking them we build networks that achieve the same accuracy as bigger ones, while reducing the number of parameters and considerably increasing computational performance. Our networks can classify a 96x96 sonar image with 98.8 - 99.7 accuracy on only 41 to 61 milliseconds on a Raspberry Pi 2, which corresponds to speedups of 28.6 - 19.7.

description: Recent results about the coexistence of ferromagnetism and unconventional superconductivity with spin-triplet Cooper pairing are reviewed on the basis of the quasi-phenomenological Ginzburg-Landau theory. The superconductivity in the mixed phase of coexistence of ferromagnetism and unconventional superconductivity is triggered by the spontaneous magnetization. The mixed phase is stable whereas the other superconducting phases that usually exist in unconventional superconductors are either unstable or metastable at relatively low temperatures in a quite narrow domain of the phase diagram and the stability properties are determined by the particular values of Landau parameters. The phase transitions from the normal phase to the phase of coexistence is of first order while the phase transition from the ferromagnetic phase to the coexistence phase can be either of first or second order depending on the concrete substance. The Cooper pair and crystal anisotropy are relevant to a more precise outline of the phase diagram shape and reduce the degeneration of the ground states of the system. The results are discussed in view of application to itinerant ferromagnetic compounds as UGe2, ZrZn2, URhGe.

description: Deuteron coalescence, during relativistic nucleus-nucleus collisions, is carried out in a model incorporating a minimal quantal treatment of the formation of the cluster from its individual nucleons by evaluating the overlap of intial cascading nucleon wave packets with the final deuteron wave function. In one approach the nucleon and deuteron center of mass wave packet sizes are estimated dynamically for each coalescing pair using its past light-cone history in the underlying cascade, a procedure which yields a parameter free determination of the cluster yield. A modified version employing a global estimate of the deuteron formation probability, is identical to a general implementation of the Wigner function formalism but can differ from the most frequent realisation of the latter. Comparison is made both with the extensive existing E802 data for Si+Au at 14.6 GeV/c and with the Wigner formalism. A globally consistent picture of the Si+Au measurements is achieved. In light of the deuteron's evident fragility, information obtained from this analysis may be useful in establishing freeze-out volumes and help in heralding the presence of high-density phenomena in a baryon-rich environment.

description: We consider mean-field interactions corresponding to Gibbs measures on interacting Brownian paths in three dimensions. The interaction is self-attractive and is given by a singular Coulomb potential. The logarithmic asymptotics of the partition function for this model were identified in the 1980s by Donsker and Varadhan [DV83] in terms of the Pekar variational formula, which coincides with the behavior of the partition function corresponding to the polaron problem under strong coupling. Based on this, Spohn ([Sp87]) made a heuristic observation that the strong coupling behavior of the polaron path measure, on certain time scales, should resemble a process, named as the itPekar process, whose distribution could somehow be guessed from the limiting asymptotic behavior of the mean-field measures under interest, whose rigorous analysis remained open. The present paper is devoted to a precise analysis of these mean-field path measures and convergence of the normalized occupation measures towards an explicit mixture of the maximizers of the Pekar variational problem. This leads to a rigorous construction of the aforementioned Pekar process and hence, is a contribution to the understanding of the ``mean-field approximation" of the polaron problem on the level of path measures. The method of our proof is based on the compact large deviation theory developed in [MV14], its extension to the uniform strong metric for the singular Coulomb interaction carried out in [KM15], as well as an idea inspired by a itpartial path exchange argument appearing in [BS97]

description: Controlling the growth of material damage is an important engineering task with plenty of real world applications. In this paper we approach this topic from the mathematical point of view by investigating an optimal boundary control problem for a damage phase-field model for viscoelastic media. We consider non-homogeneous Neumann data for the displacement field which describe external boundary forces and act as control variable. The underlying hyberbolic-parabolic PDE system for the state variables exhibit highly nonlinear terms which emerge in context with damage processes. The cost functional is of tracking type, and constraints for the control variable are prescribed. Based on recent results from [M. H. Farshbaf-Shaker, C. Heinemann: A phase field approach for optimal boundary control of damage processes in two-dimensional viscoelastic media. Math. Models Methods Appl. Sci. 25 (2015), 2749--2793], where global-in-time well-posedness of strong solutions to the lower level problem and existence of optimal controls of the upper level problem have been established, we show in this contribution differentiability of the control-to-state mapping, well-posedness of the linearization and existence of solutions of the adjoint state system. Due to the highly nonlinear nature of the state system which has by our knowledge not been considered for optimal control problems in the literature, we present a very weak formulation and estimation techniques of the associated adjoint system. For mathematical reasons the analysis is restricted here to the two-dimensional case. We conclude our results with first-order necessary optimality conditions in terms of a variational inequality together with PDEs for the state and adjoint state system.

description: Nonlinearity plays a crucial role in deep neural networks. In this paper, we investigate the degree to which the nonlinearity of the neural network is essential. For this purpose, we employ the Koopman operator, extended dynamic mode decomposition, and the tensor-train format. The Koopman operator approach has been recently developed in physics and nonlinear sciences; the Koopman operator deals with the time evolution in the observable space instead of the state space. Since we can replace the nonlinearity in the state space with the linearity in the observable space, it is a hopeful candidate for understanding complex behavior in nonlinear systems. Here, we analyze learned neural networks for the classification problems. As a result, the replacement of the nonlinear middle layers with the Koopman matrix yields enough accuracy in numerical experiments. In addition, we confirm that the pruning of the Koopman matrix gives sufficient accuracy even at high compression ratios. These results indicate the possibility of extracting some features in the neural networks with the Koopman operator approach.

Dominant Kinetic Pathways of Graphene Growth in Chemical Vapor Deposition: The Role of Hydrogen

description: The most popular way to produce graphene nowadays is chemical vapor deposition, where, surprisingly, H$_2$ gas is routinely supplied even though it is a byproduct itself. In this study, by identifying dominant growing pathways via multiscale simulations, we unambiguously reveal the central role hydrogen played in graphene growth. Hydrogen can saturate the edges of a growing graphene island to some extent, depending on the H$_2$ pressure. Although graphene etching by hydrogen has been observed in experiment, hydrogen saturation actually stabilizes graphene edges by reducing the detachment rates of carbon-contained species. Such a new picture well explains some puzzling experimental observations and is also instrumental in growth protocol optimization for two-dimensional atomic crystal van der Waals epitaxy.

Propagation of dark solitons of DNLS equation along a large-scale background

description: We study dynamics of dark solitons in the theory of the DNLS equation by the method based on imposing the condition that this dynamics must be Hamiltonian. Combining this condition with Stokes' remark that relationships for harmonic linear waves and small-amplitude soliton tails satisfy the same linearized equations, so the corresponding solutions can be converted one into the other by replacement of the packet's wave number $k$ by $iκ$, $κ$ being the soliton's inverse half-width, we find the Hamiltonian and the canonical momentum of the soliton's motion. The Hamilton equations are reduced to the Newton equation whose solutions for some typical situations are compared with exact numerical solutions of the DNLS equation.

On the application of subspace migration from scattering matrix with constant-valued diagonal elements in microwave imaging

description: We consider the application of a subspace migration (SM) algorithm to quickly identify small objects in microwave imaging. In various problems, it is easy to measure the diagonal elements of the scattering matrix if the location of the transmitter and the receiver is the same. To address this issue, several studies have been conducted by setting the diagonal elements to zero. In this paper, we generalize the imaging problem by setting diagonal elements of the scattering matrix as a constant with the application of SM. To show the applicability of SM and its dependence on the constant, we show that the imaging function of SM can be represented in terms of an infinite series of the Bessel functions of integer order, antenna number and arrangement, and applied constant. This result enables us to discover some further properties, including the unique determination of objects. We also demonstrated simulation results with synthetic data to support the theoretical result.

description: We present new aperture synthesis CO maps of the Antennae (NGC 4038/39) obtained with the Caltech Millimeter Array. These sensitive images show molecular emission associated with the two nuclei and a partial ring of star formation to the west of NGC 4038, as well as revealing the large extent of the extra-nuclear region of star formation (the ``overlap region''), which dominates the CO emission from this system. The largest molecular complexes have masses of 3-6x10^8 M_sun, typically an order of magnitude larger than the largest structures seen to date in more quiescent galaxy disks. The extremely red luminous star clusters identified previously with HST are well-correlated with the CO emission, which supports the conclusion that they are highly embedded young objects rather than old globular clusters. There is an excellent correlation between the CO emission and the 15 micron emission seen with ISO, particularly for the brightest regions. The most massive complexes in the overlap region have similar [NeIII]/[NeII] ratios, which implies that all these regions are forming many massive stars. However, only the brightest mid-infrared peak shows strong, rising continuum emission longward of 10 microns, indicative of very small dust grains heated to high temperatures by their proximity to nearby luminous stars. Since these grains are expected to be removed rapidly from the immediate environment of the massive stars, it is possible that this region contains very young (< 1 Myr) sites of star formation. Alternatively, fresh dust grains could be driven into the sphere of influence of the massive stars, perhaps by the bulk motions of two giant molecular complexes. The kinematics and morphology of the CO emission in this region provide some support for this second scenario.

description: We call a coloring of the edge set of a graph G a b-bounded coloring if no color is used more than b times. We say that a subset of the edges of G  is rainbow if each edge is of a different color. A graph has property A(b,H) if every b-bounded coloring of its edges has a rainbow copy of H . We estimate the threshold for the random graph Gn,p to have property A(b,H).
