description: Recent studies revealed that carbonate slopes can have similar architectural elements as their siliciclastic counterparts. This study uses a large regional 3D seismic dataset to map and quantify carbonate and mixed carbonate-siliciclastic slope architectural elements to generate an updated model of these slope systems. The research area of this project is the upper slope to toe-of-slope region of Miocene carbonates in the Browse Basin of the NW Shelf of Australia covering a total of over 25,000 km² in area. This slope can be divided into three components: (1) a low angle transition between carbonate platform margins and the upper slope; (2) a steep upper slope riddled with low-sinuosity, line-fed canyons; and (3) a low angle lower slope with a mix of sinuous channel-levee systems, mass transport deposits, and slope fans. The slope channels were sourced from large carbonate platforms along the shelf. Slope architectural elements, such as canyons, channel-levee systems, mass transport deposits, and fans, were imaged to extract geomorphic data such as length, gradient, aspect ratio, and sinuosity. Canyons are defined as channels between 0.5 to 1.5 km wide and 80 to 250 m deep that are relatively straight (sinuosity of 1.00-1.14) and set upon the steeper gradients of the upper slope (2.4° - 11°). Some canyons transformed downstream into channel-levee systems, which are narrower and shallower and more sinuous (1.05-1.30), developing on a slope angle of 1.2° - 4.6°. In many cases, the evolution of canyons into channel-levee systems can be clearly observed in seismic data in the middle-outer slope. The development of the channel-levee systems in the lower slope is controlled by slope gradient and concavity. The channel-levee system can be eroded by large mass transport deposits. This high-resolution regional 3D seismic dataset provides an excellent example of a carbonate slope to toe-of-slope morphology that can be used to generate an updated model of such systems and provide a new analogue for exploring other carbonate slope and basin environments.

description: We calculate the second-order corrections to the atomic energy level shifts in ordinary and muonic deuterium due to virtual excitations of the deuteron which are important for ongoing and planned precise experiments in these systems. For light atoms a method can be used in which the shift is expressed as integrals over the longitudinal and transverse inelastic structure functions of the nucleus. We employ the structure functions arising from separable NN potentials of the Yamaguchi and Tabakin form which can be evaluated analytically. Special emphasis is put on gauge invariance which requires a consistent inclusion of interaction currents and seagull terms. The effect of the D-wave component of the deuteron is investigated for the leading longitudinal contribution. We also estimate the shift for pionic deuterium.

The method is based on energy estimates, a monotonicity formula, and the equipartition of the energy at each time.

description: In the field of lung cancer research, particularly in the analysis of overall survival (OS), artificial intelligence (AI) serves crucial roles with specific aims. Given the prevalent issue of missing data in the medical domain, our primary objective is to develop an AI model capable of dynamically handling this missing data. Additionally, we aim to leverage all accessible data, effectively analyzing both uncensored patients who have experienced the event of interest and censored patients who have not, by embedding a specialized technique within our AI model, not commonly utilized in other AI tasks. Through the realization of these objectives, our model aims to provide precise OS predictions for non-small cell lung cancer (NSCLC) patients, thus overcoming these significant challenges. We present a novel approach to survival analysis with missing values in the context of NSCLC, which exploits the strengths of the transformer architecture to account only for available features without requiring any imputation strategy. More specifically, this model tailors the transformer architecture to tabular data by adapting its feature embedding and masked self-attention to mask missing data and fully exploit the available ones. By making use of ad-hoc designed losses for OS, it is able to account for both censored and uncensored patients, as well as changes in risks over time. We compared our method with state-of-the-art models for survival analysis coupled with different imputation strategies. We evaluated the results obtained over a period of 6 years using different time granularities obtaining a Ct-index, a time-dependent variant of the C-index, of 71.97, 77.58 and 80.72 for time units of 1 month, 1 year and 2 years, respectively, outperforming all state-of-the-art methods regardless of the imputation method used.

description: This paper revisits the classical inference results for profile quasi maximum likelihood estimators (profile MLE) in the semiparametric estimation problem. We mainly focus on two prominent theorems: the Wilks phenomenon and Fisher expansion for the profile MLE are stated in a new fashion allowing finite samples and model misspecification. The method of study is also essentially different from the usual analysis of the semiparametric problem based on the notion of the hardest parametric submodel. Instead we apply the local bracketing and the upper function devices from Spokoiny (2011). This novel approach particularly allows to address the important issue of the effective target and nuisance dimension and it does not involve any pilot estimator of the target parameter. The obtained nonasymptotic results are surprisingly sharp and yield the classical asymptotic statements including the asymptotic normality and efficiency of the profile MLE. The general results are specified to the important special cases of an i.i.d. sample.

description: The Andreev transport properties of double quantum dot based Cooper pair splitters with one superconducting and two normal leads are studied theoretically in the Kondo regime. The influence of the superconducting pairing correlations on the local density of states, Andreev transmission coefficient and Cooper pair splitting efficiency is thoroughly analyzed. It is shown that finite superconducting pairing potential quickly suppresses the SU(2) Kondo effect, which can however reemerge for relatively large values of coupling to superconductor. In the SU(4) Kondo regime, a crossover from the SU(4) to the SU(2) Kondo state is found as the coupling to superconductor is enhanced. The analysis is performed by means of the density-matrix numerical renormalization group method.

description: The present note deals with a nonstandard systems of differential equations describing a two-species phase segregation. This system naturally arises in the asymptotic analysis carried out recently by the same authors, as the diffusion coefficient in the equation governing the evolution of the order parameter tends to zero. In particular, an existence result has been proved for the limit system in a very general framework. On the contrary, uniqueness was shown by assuming a constant mobility coefficient. Here, we generalize this result and prove a continuous dependence property in the case that the mobility coefficient suitably depends on the chemical potential.
Longitudinal versus transverse spheroidal vibrational modes of an elastic sphere

description: Analysis of the spheroidal modes of vibration of a free elastic sphere show that they can be qualitatively grouped into two categories: primarily longitudinal and primarily transverse. This is not a sharp distinction. However, there is a relatively stark contrast between the two kinds of modes. Primarily transverse modes have a small divergence and have frequencies that are almost functionally independent of the longitudinal speed of sound. Analysis of inelastic light scattering intensity from confined acoustic phonons in nanoparticles requires an understanding of this qualitative distinction between different spheroidal modes. In addition, some common misconceptions about spheroidal modes are corrected.

description: The reduction of dimensionality is an efficient pathway to boost the performances of thermoelectric materials, it leads to the quantum confinement of the carriers and thus to large Seebeck coefficients (S) and it also suppresses the thermal conductivity by increasing the phonon scattering processes. However, quantum confinement in superlattices is not always easy to achieve and needs to be carefully validated. In the past decade, large values of S have been measured in (SrTiO3)/(SrTi0:8Nb0:2O3) superlattices (Nat. Mater. 6, 129 (2007) and Appl. Phys. Lett. 91, 192105 (2007)). In the $δ$-doped compound, the measured S was almost 6 times larger than that of the bulk material. This huge increase has been attributed to the two dimensional confinement of the carriers in the doped regions. In this work, we demonstrate that the experimental data can be well explained quantitatively within the scenario in which electrons are delocalized in both in-plane and growth directions, hence strongly suggesting that the confinement picture in these superlattices may be unlikely.

description: We study the computational complexity of simulating the time-dependent expectation value of a local operator in a one-dimensional quantum system by using temporal matrix product states. We argue that such cost is intimately related to that of encoding temporal transition matrices and their partial traces. In particular, we show that we can upper-bound the rank of these reduced transition matrices by the one of the Heisenberg evolution of local operators, thus making connection between two apparently different quantities, the temporal entanglement and the local operator entanglement. As a result, whenever the local operator entanglement grows slower than linearly in time, we show that computing time-dependent expectation values of local operators using temporal matrix product states is likely advantageous with respect to computing the same quantities using standard matrix product states techniques.

description: A nonstandard systems of differential equations describing two-species phase segregation is considered. This system naturally arises in the asymptotic analysis recently done by Colli, Gilardi, Krejci, and Sprekels as the diffusion coefficient in the equation governing the evolution of the order parameter tends to zero. In particular, a well-posedness result is proved for the limit system. This paper deals with the above limit problem in a less general but still very significant framework and provides a very simple proof of further regularity for the solution. As a byproduct, a simple uniqueness proof is given as well.

description: The Pettet Limestone of the Wright Mountain field on the northeastern flank of the East Texas Basin in Smith County, Texas has been a carbonate hydrocarbon reservoir for nearly 70 years. The Upper Sligo interval (Pettet Limestone) was deposited during the lower most part of the Aptian composite section (124 to ~123 Ma) putting the Pettet carbonate strata in a transgressive setting that onlapped continental to shallow marine siliciclastics. The goals of this investigation include: (1) defining the regional and local depositional setting, (2) characterizing the carbonate and siliciclastic lithofacies that compose the section, (3) creating a depositional model that explains the lithofacies in the cored Pettet B and C units, (4) characterizing the type and abundance of organic matter within the lithofacies, (5) describing the paragenesis of the lithofacies, and (6) evaluating the pore types and reservoir quality of the different lithofacies. The depositional model is developed to help understand comparable skeletal oolitic lime packstone and grainstone deposits occurring in other oil and gas fields. After investigation, the Pettet Limestone of the Wright Mountain field was deemed an off-shoal complex (lateral to shoal body). The Pettet B and C units show evidence of a shoaling upward sequence but not necessarily into complete shoal-water complexes (higher energy carbonate shallow-water complexes). The model proposed suggests the Pettet B and C were deposited laterally adjacent to the shoal, in a slightly deeper, lower-energy setting towards the bottom of fair-weather wave base. Products of resedimentation are present in the Pettet Limestone and are likely results of storm remobilization, transport, and subsequent deposition.

description: The survey for DUST in Nearby Galaxies with Spitzer (DUSTiNGS) identified several candidate Asymptotic Giant Branch (AGB) stars in nearby dwarf galaxies and showed that dust can form even in very metal-poor systems (Z ~ 0.008 $Z_\odot$). Here, we present a follow-up survey with WFC3/IR on the Hubble Space Telescope (HST), using filters that are capable of distinguishing carbon-rich (C-type) stars from oxygen-rich (M-type) stars: F127M, F139M, and F153M. We include six star-forming DUSTiNGS galaxies (NGC 147, IC 10, Pegasus dIrr, Sextans B, Sextans A, and Sag DIG), all more metal-poor than the Magellanic Clouds and spanning 1 dex in metallicity. We double the number of dusty AGB stars known in these galaxies and find that most are carbon rich. We also find 26 dusty M-type stars, mostly in IC 10. Given the large dust excess and tight spatial distribution of these M-type stars, they are most likely on the upper end of the AGB mass range (stars undergoing Hot Bottom Burning). Theoretical models do not predict significant dust production in metal-poor M-type stars, but we see evidence for dust excess around M-type stars even in the most metal-poor galaxies in our sample (12+log(O/H) = 7.26-7.50). The low metallicities and inferred high stellar masses (up to ~10 $M_\odot$) suggest that AGB stars can produce dust very early in the evolution of galaxies (~30 Myr after they form), and may contribute significantly to the dust reservoirs seen in high-redshift galaxies.

description: The objectives of this research were to determine if the content of mathematics as a whole (not distinct math themes as in Algebra, 2D geometry, 3D geometry, trigonometry, complex numbers, probability, etc) is statistically and significantly associated with student’s anxiety; and to examine the extent of the association between teacher’s practices, through cognitive and social interactions, and student’s math anxiety. Student’s gender was not a factor tackled by the study thus gender specific differences in classes and levels towards math anxiety were not tested. In addition, the study did not compare the impact of math anxiety on students in middle schools to that of students in the secondary level. The study utilized a two-phase design labelled as an explanatory design “descriptive quantitative data collection followed by a qualitative design through structured interviews to further understand and interpret the data collected from the quantitative findings”. The instrument employed for data collection was a 5 Point-Likert scale survey questionnaire of standardized items developed by the universities of Georgia, Southampton, New Hampshire and Windsor Scholarship, and the Theo Wubbels and Jack Levy’s Student Questionnaire of Teacher Interaction. The statistics used for the data collected concerning the study were descriptive and inferential statistics (the mean, the standard deviation, the mode and the median), and the Pearson’s Chi-Square test. Through the study results, the researcher concluded that math content as a whole is statistically and significantly associated with student’s math anxiety in the intermediate and secondary levels which indicates that the current curriculum is built on knowledge and not proper understanding of the subject material and that the content of mathematics in diverse classes is stuffed to the limit that it may cause students daily anxiety thus their math specific deficits cannot be properly dealt from one class to another, and that teacher’s practices represent a main reason that influences student’s math anxiety; and even-though, some of these practices derived from weak to moderate to strong association with student’s anxiety, the researcher deduced that items concerning teacher’s practices in lower levels should be seriously treated for it may be causing students math anxiety that may probably keep up with them in later stages. Teachers should identify their teaching approaches, methods, strategies and techniques for student’s successful learning environment in the intermediate and secondary levels and for sure in lower classes.

The interactions among electrons due to the exchange of spin fluctuations profoundly change the probability of occupation $(n_{{\bf k},σ})$ of states of momentum {\bf k} and spin $σ$ which is the central quantity in the calculations of OS and KE. Normal and superconducting states are considered as a function of temperature. Both integrals are found to depend importantly on interactions and an independent electron model is inadequate.

New coarse grid operators based on homogenized operators are introduced to restore the fast convergence rate of multigrid methods. Finite difference approximations are used for the discretization of the equations. Convergence analysis is based on the homogenization theory. Proofs are given for a two-level multigrid method with the homogenized coarse grid operator for two classes of two dimensional elliptic equations with Dirichlet boundary conditions."

description: This paper is concerned with the variational approach in weighted Sobolev spaces to time-harmonic elastic scattering by two-dimensional unbounded rough surfaces. The rough surface is supposed to be the graph of a bounded and uniformly Lipschitz continuous function, on which the total elastic displacement satisfies either the Dirichlet or impedance boundary condition. We establish uniqueness and existence results for both elastic plane and point source (spherical) wave incidence, following the recently developed variational approach in [SIAM J. Math. Anal., 42: 6 (2010), pp. 2554-2580] for the Helmholtz equation. This paper extends our previous solvability results [SIAM J. Math. Anal., 44: 6 (2012), pp. 4101-4127] in the standard Sobolev space to the weighted Sobolev spaces.

description: Many natural or human-made systems encompassing local reactions and diffusion processes exhibit spatially distributed patterns of some relevant dynamical variable. These interactions, through self-organization and critical phenomena, give rise to power-law distributions, where emergent patterns and structures become visible across vastly different scales. Recent observations reveal power-law distributions in the spatial organization of, e.g., tree clusters and forest patch sizes. Crucially, these patterns do not follow a spatially periodic order but rather a statistical one. Unlike the spatially periodic patterns elucidated by the Turing mechanism, the statistical order of these particular vegetation patterns suggests an incomplete understanding of the underlying mechanisms. Here, we present a novel self-segregation mechanism, driving the emergence of power-law scalings in pattern-forming systems. The model incorporates an Allee-logistic reaction term, responsible for the local growth, and a nonlinear diffusion process accounting for positive interactions and limited resources. According to a self-organized criticality (SOC) principle, after an initial decrease, the system mass reaches an analytically predictable threshold, beyond which it self-segregates into distinct clusters, due to local positive interactions that promote cooperation. Numerical investigations show that the distribution of cluster sizes obeys a power-law with an exponential cutoff.

description: We apply the Lee-Suzuki iteration method to calculate the linked-folded diagram series for a new Nijmegen local NN potential. We obtain an exact starting-energy-independent effective two-body interaction for a multi-shell, no-core, harmonic-oscillator model space. It is found that the resulting effective-interaction matrix elements can be well approximated by the Brueckner G-matrix elements evaluated at starting energies selected in a simple way. These starting energies are closely related to the energies of the initial two-particle states in the ladder diagrams. The ``exact'' and approximate effective interactions are used to calculate the energy spectrum of 6Li in order to test the utility of the approximate form.

description: We consider point clouds obtained as random samples of a measure on a Euclidean domain. A graph representing the point cloud is obtained by assigning weights to edges based on the distance between the points they connect. Our goal is to develop mathematical tools needed to study the consistency, as the number of available data points increases, of graph-based machine learning algorithms for tasks such as clustering. In particular, we study when is the cut capacity, and more generally total variation, on these graphs a good approximation of the perimeter (total variation) in the continuum setting. We address this question in the setting of Γ-convergence. We obtain almost optimal conditions on the scaling, as number of points increases, of the size of the neighborhood over which the points are connected by an edge for the Γ-convergence to hold. Taking the limit is enabled by a transportation based metric which allows to suitably compare functionals defined on different point clouds.

description: Additional file 1. Generation of recombinant LSDV viruses expressing GFP. (A) GFP was cloned under a Vaccinia virus synthetic promoter (MVA-pS, [40]) flanked by sequences with homology to the ends of LSDV05 and LSDV06 genes. Broad arrows in the scheme represent the orientations of viral ORFs. Thin coloured lines represent predicted amplicon sizes using the specified primer sets (detailed in Additional file 2). (B) LSDV-GFP viruses were screened for homogeneity by endpoint PCR. PCR products of DNA extracted from MDBK cells, either mock infected or infected with parental and recombinant LSDV strains, were separated by agarose gel electrophoresis using the three primer sets (A-C) illustrated above. Amplification of DNA from recombinant viruses with flanking primers gave rise to a single amplification product confirming proper integration of the EGFP cassette into the targeted LSDV genomic site with no traces of an amplicon derived from parental LSDV DNA.

description: We solve the Schroedinger equation for an interacting spin-chain locally coupled to a quantum environment with a specific degeneracy structure. The reduced dynamics of the whole spin-chain as well as of single spins is analyzed. We show, that the total spin-chain relaxes to a thermal equilibrium state independently of the internal interaction strength. In contrast, the asymptotic states of each individual spin are thermal for weak but non-thermal for stronger spin-spin coupling. The transition between both scenarios is found for couplings of the order of $0.1 \times ΔE$, with $ΔE$ denoting the Zeeman-splitting. We compare these results with a master equation treatment; when time averaged, both approaches lead to the same asymptotic state and finally with analytical results.

description: Supervised classification algorithms are used to solve a growing number of real-life problems around the globe. Their performance is strictly connected with the quality of labels used in training. Unfortunately, acquiring good-quality annotations for many tasks is infeasible or too expensive to be done in practice. To tackle this challenge, active learning algorithms are commonly employed to select only the most relevant data for labeling. However, this is possible only when the quality and quantity of labels acquired from experts are sufficient. Unfortunately, in many applications, a trade-off between annotating individual samples by multiple annotators to increase label quality vs. annotating new samples to increase the total number of labeled instances is necessary. In this paper, we address the issue of faulty data annotations in the context of active learning. In particular, we propose two novel annotation unification algorithms that utilize unlabeled parts of the sample space. The proposed methods require little to no intersection between samples annotated by different experts. Our experiments on four public datasets indicate the robustness and superiority of the proposed methods in both, the estimation of the annotator's reliability, and the assignment of actual labels, against the state-of-the-art algorithms and the simple majority voting.

description: The Costa Rican convergent margin has been a primary site for studies of subduction erosion because it is a documented example of an erosional subduction zone with tectonic erosion by seamount, plateau, and ridge collision. Previous work has explored both modern-day and historical evidence for ongoing subduction of a rough seafloor at Costa Rica that has left erosional scars on seafloor bathymetry, but the impacts on slope sedimentation, the tectonic removal of pieces of the upper plate, and the long-term sub seafloor geologic record left behind from these events is poorly understood. To further explore the effects of subducting plate bathymetric features on the long-term structural and stratigraphic record, this study used three-dimensional kinematic restoration to examine trends in uplift and subsidence over time and potentially identify periods of seamount subduction. This study utilized a 3D seismic reflection volume along with interpreted well log data to create a finite element model of major structural and stratigraphic features within the study region. The 3D model was then kinematically restored using Paradigm’s SKUA-GoCAD Kine3D, providing a 2.2 Myr history of three-dimensional motion for the modeled area. Results start at 2.2 Ma when subaerial uplift elevated the margin 1.2 km corresponding to a regional unconformity established from drilling. This event was followed by a period of subsidence before a short pulse of uplift occurred in a ~9 km wide circular area on the shelf. Recent (1.3Ma – 0Ma) enhanced subsidence in the same region has led to the formation of a circular bathymetric depression on the seafloor that resemble similar features farther north interpreted as seamount impacts. This leads me to conclude that a subducted seamount (~9 km at the base, 1.5 km height) passed through the study region ~1.8 Ma leaving behind a weakened region of underplated sediments. Over time, basal erosion of this area has removed 180 km³ of material. The models reveal that seamount subduction causes erosion both by transfer of material from the upper plate in front of the seamount, and by weakening the upper plate to promote erosion in the wake of the seamount, resulting in distinctive seafloor indentations.

description: The Lippmann equation is considered as universal relationship between interfacial tension, double layer charge, and cell potential. Based on the framework of continuum thermo-electrodynamics we provide some crucial new insights to this relation. In a previous work we have derived a general thermodynamic consistent model for electrochemical interfaces, which showed a remarkable agreement to single crystal experimental data. Here we apply the model to a curved liquid metal electrode. If the electrode radius is large compared to the Debye length, we apply asymptotic analysis methods and obtain the Lippmann equation. We give precise definitions of the involved quantities and show that the interfacial tension of the Lippmann equation is composed of the surface tension of our general model, and contributions arising from the adjacent space charge layers. This finding is confirmed by a comparison of our model to experimental data of several mercury-electrolyte interfaces. We obtain qualitative and quantitative agreement in the 2V potential range for various salt concentrations. We also discuss the validity of our asymptotic model when the electrode curvature radius is comparable to the Debye length.

description: The van Roosbroeck system describes the semi-classical transport of free electrons and holes in a self-consistent electric field using a drift-diffusion approximation. It became the standard model to describe the current flow in semiconductor devices at macroscopic scale. Typical devices modeled by these equations range from diodes, transistors, LEDs, solar cells and lasers to quantum nanostructures and organic semiconductors. The report provides an introduction into numerical methods for the van Roosbroeck system. The main focus lies on the Scharfetter-Gummel finite volume discretization scheme and recent efforts to generalize this approach to general statistical distribution functions.
Solving Witten's string field theory using the butterfly state

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We solve the equation of motion of Witten's cubic open string field theory in a series expansion using the regulated butterfly state. The expansion parameter is given by the regularization parameter of the butterfly state, which can be taken to be arbitrarily small. Unlike the case of level truncation, the equation of motion can be solved for an arbitrary component of the Fock space up to a positive power of the expansion parameter. The energy density of the solution is well-defined and remains finite even in the singular butterfly limit, and it gives approximately 68% of the D25-brane tension for the solution at the leading order. Moreover, it simultaneously solves the equation of motion of vacuum string field theory, providing support for the conjecture at this order. We further improve our ansatz by taking into account next-to-leading terms, and find two numerical solutions which give approximately 88% and 109%, respectively, of the D25-brane tension for the energy density. These values are interestingly close to those by level truncation at level 2 without gauge fixing studied by Rastelli and Zwiebach and by Ellwood and Taylor.

Phase Plane Analysis of the Photometrical Variations of Long-Period Variables

description: Using the phase plane diagrams, the phase light curves of a group of the Mira-type stars and semi-regular variables are analyzed. As generalized coordinates x and $\dot{x}$, we have used m - the brightness of the star and its phase derivative. We have used mean phase light curves using observations of various authors. The data typically span a large time interval (nearly a century). They were compiled from the databases of AAVSO, AFOEV, VSOLJ, ASAS and approximated using a trigonometric polynomial of statistically optimal degree. As the resulting approximation characterizes the auto-oscillation process, which leads to a photometrical variability, the phase diagram corresponds to a limit cycle. For all stars studied, the limit cycles were computed. For a simple sine-like light curve, in e.g., L$_2$ Pup, the limit cycle is a simple ellipse. In a case of more complicated light curve, in which harmonics are statistically significant, the limit cycle has deviations from the ellipse. In an addition to a classical analysis, we use the error estimates of the smoothing function and its derivative to constrain an "error corridor" in the phase plane.
