description: We show that by employing the standard projected curvature as a measure of spatial curvature, we can make a certain generalization of optical geometry (Abramowicz and Lasota 1997, Class. Quantum Grav. 14 (1997) A23). This generalization applies to any spacetime that admits a hypersurface orthogonal shearfree congruence of worldlines. This is a somewhat larger class of spacetimes than the conformally static spacetimes assumed in standard optical geometry. In the generalized optical geometry, which in the generic case is time dependent, photons move with unit speed along spatial geodesics and the sideways force experienced by a particle following a spatially straight line is independent of the velocity. Also gyroscopes moving along spatial geodesics do not precess (relative to the forward direction). Gyroscopes that follow a curved spatial trajectory precess according to a very simple law of three-rotation. We also present an inertial force formalism in coordinate representation for this generalization. Furthermore, we show that by employing a new sense of spatial curvature (Jonsson, Class. Quantum Grav. 23 (2006) 1) closely connected to Fermat's principle, we can make a more extensive generalization of optical geometry that applies to arbitrary spacetimes. In general this optical geometry will be time dependent, but still geodesic photons move with unit speed and follow lines that are spatially straight in the new sense. Also, the sideways experienced (comoving) force on a test particle following a line that is straight in the new sense will be independent of the velocity.

description: The face stability of tunnels in soft grounds is investigated in this paper. In the framework of the kinematic approach of limit analysis, a two-dimensional failure mechanism based on the translational and rotational movement of rigid blocks is proposed in order to calculate the critical face pressure by employing the optimization tools in Matlab software. In order to verify the proposed mechanism, the results obtained from this failure mechanism were compared to those of the finite element simulations (Plaxis software) and other existing approaches. This Mechanism is presented in such a way that can consider the arching effect in tunnel face collapse. The analytical results obtained from the proposed mechanism are in good agreement with the numerical results. The results show that the internal friction angle of the soil has a great influence on the necessary face pressure and as the internal friction angle of soil increases, the support pressure required to maintain the stability of tunnel face decreases.

description: We propose a purely data-driven model predictive control (MPC) scheme to control unknown linear time-invariant systems with guarantees on stability and constraint satisfaction in the presence of noisy data. The scheme predicts future trajectories based on data-dependent Hankel matrices, which span the full system behavior if the input is persistently exciting. This paper extends previous work on data-driven MPC by including a suitable constraint tightening which ensures that the closed-loop trajectory satisfies desired pointwise-in-time output constraints. Furthermore, we provide estimation procedures to compute system constants related to controllability and observability, which are required to implement the constraint tightening. The practicality of the proposed approach is illustrated via a numerical example.

description: For a given input DNA fragment (clone), we study the distribution of the output sequence (observation) from an automated sequencer. Primary emphasis is placed on obtaining likelihood based procedures associated with the important computational tasks involved in a shotgun sequencing strategy: ranking multiple sequence alignments, estimating a consensus sequence, and assessing the confidence of a reconstruction. These tasks rely on the important problem of deciding which pairs of data sequences arise from overlapping fragments. The overlap detection problem is formulated from the standpoint of point estimation as well as test of hypotheses. Using theoretical models for data under no errors and under substitution type errors, the performance of maximum likelihood, maximum posterior estimates for overlap are compared. Likelihood ratio tests of overlap versus no overlap are evaluated. The goal there is to understand the relationship between different error processes on procedures to detect when cloned fragments overlap. Because the underlying biochemical mechanisms responsible for the sequence reading errors are poorly understood, we have proposed new definitions and methods for characterizing error events when discrepancies are evident. Using results from our data study, a probabilistic model, Run Extension and Contraction (RECO), for sequence read errors is developed. Methods for parameter estimation and overlap detection under the RECO model are described. Analysis of two independent experimentally derived data sets demonstrates that our RECO model provides a good fit to the majority of sequence read errors.

Hartree-Fock approach to nuclear matter and finite nuclei with M3Y-type nucleon-nucleon interactions

description: By introducing a density-dependent contact term, M3Y-type interactions applicable to the Hartree-Fock calculations are developed. In order to view basic characters of the interactions, we carry out calculations on the uniform nuclear matter as well as on several doubly magic nuclei. It is shown that a parameter-set called M3Y-P2 describes various properties similarly well to the Skyrme SLy5 and/or the Gogny D1S interactions. A remarkable difference from the SLy5 and the D1S interactions is found in the spin-isospin properties in the nuclear matter, to which the one-pion-exchange potential gives a significant contribution. Affecting the single-particle energies, this difference may play a certain role in the new magic numbers in unstable nuclei.

description: In this paper, we consider the nonlinear Schrödinger equation (NLS) with a general homogeneous nonlinearity in dimensions up to three. We assume that the degree (i.e., power) of the nonlinearity is such that the equation is mass-subcritical and short-range. We establish global well-posedness (GWP) and scattering for small data in the standard weighted space for a class of homogeneous nonlinearities, including non-gauge-invariant ones. Additionally, we include the case where the degree is less than or equal to the Strauss exponent. When the nonlinearity is not gauge-invariant, the standard Duhamel formulation fails to work effectively in the weighted Sobolev space; for instance, the Duhamel term may not be well-defined as a Bochner integral. To address this issue, we introduce an alternative formulation that allows us to establish GWP and scattering, even in the presence of poor time continuity of the Duhamel term.

description: The advent of molecular innovations in the 21st century enabled greater understanding of the human genome and elucidated the pathophysiology underlying many genodermatoses. These innovations are leading to a rapidly growing therapeutic armamentarium for patients with previously untreatable genetic skin diseases targeting the gene or downstream pathways that impact the phenotype. These advanced molecular technologies allow for reversal of underlying genetic defects or restoration of functional products via gene, protein, and cell therapy approaches. Dermatologists should familiarize themselves with these new and emerging therapeutic options to adequately care for patients affected by genodermatoses in this era of rapidly advancing treatments and molecular interventions. Our focus for the current review is to present a comprehensive update on new and emerging targeted treatments for genodermatoses with an emphasis on the pharmacologic and molecular mechanisms of therapeutic classes. We will discuss the indications for therapeutic interventions and new technological advancements in treatment across the spectrum of genodermatoses.

description: The spherical Hartree-Fock approximation is applied to the $abinitio$ no-core shell model, with a realistic effective nucleon-nucleon interaction in order to investigate the range of its utility. Hartree-Fock results for binding energies, one-body density distributions and occupation probabilities are compared with results from exact diagonalization in similar model spaces. We show that this mean field approximation, especially with second order corrections, is able to provide some useful approximatons for $^4He$ and $^{16}O$. We also explore the physical insights provided by the Hartree-Fock results for single-particle properties such as spin-orbit splittings. We find single particle state ordering consistent with the phenomenological shell model.

We consider both energy weighted (EWSR) and non-energy weighted (NEWSR) sum rules. We use a schematic Hamiltonian to stress the distinctive roles of T=1 and T=0 pair interactions and correlations in the sum rules. Numerical results for 44Ti are presented for both schematic and realistic interactions.

Year: 2023

description: The purpose of this research is to investigate and analyze the perception of school principals in Aseer educational district in Saudi Arabia regarding the importance of principalship. It also attempts to determine the elements of a training program for all school principals. The study involves 101 (30%) of the 334 school principals in Aseer educational district. One hundred and one questionnaires, therefore, were sent to the randomly selected principals. The response rate was high and encouraging: 93 questionnaires were returned from which 90 were useable. A researcher-developed Likert five-scale questionnaire was constructed--"strongly disagree" as being 1 on the scale and "strongly agree" as being 5. For the purpose of statistical analysis, the Statistical Package for Social Science (SPSS) was used to analyze the collected data. Descriptive statistics were used to report the data regarding perception (research questions 1, 2, and 3). Three independent variables (evaluation of the previous training, the importance of principalship, and the framework of the proposed training program) and three dependent variables (the respondents' degree, experience in educational administration, and their previous training) were developed and tested by correlation using inferential statistic, t-test and chi-square techniques. Although the perception of respondents regarding the importance of principalship's skills was high, their view of the effectiveness of their previous training program was low. Some significant results also were reported relative to the impact of respondents' degree, experience, and previous training on their perception towards the developed independent variables. In sum, the conclusions of this study produce evidence to support the need for further training of school principals not only in Aseer educational district but also throughout Saudi Arabia. Thus, a proposed framework of a training model is recommended based on the explored models of the United States.

description: Exotic magnetic structures, such as magnetic skyrmions and domain walls, are becoming more important in nitrogen-vacancy center scanning magnetometry. However, a systematic imaging approach to mapping stray fields with fluctuation of several milliteslas generated by such structures is not yet available. Here we present a scheme to image a millitesla magnetic field by tracking the magnetic resonance frequency, which can record multiple contour lines for a magnetic field. The radial basis function algorithm is employed to reconstruct the magnetic field from the contour lines. Simulations with shot noise quantitatively confirm the high quality of the reconstruction algorithm. The method was validated by imaging the stray field of a frustrated magnet. Our scheme had a maximum detectable magnetic field gradient of 0.86 mT per pixel, which enables the efficient imaging of millitesla magnetic fields.

description: We study nonparametric identifiability of finite mixture models of k-variate data with M subpopulations, in which the components of the data vector are independent conditional on belonging to a subpopulation. We provide a sufficient condition for nonparametrically identifying M subpopulations when k 3. Our focus is on the relationship between the number of values the components of the data vector can take on, and the number of identifiable subpopulations. Intuition would suggest that if the data vector can take many different values, then combining information from these different values helps identification. Hall and Zhou (2003) show, however, when k = 2, two-component finite mixture models are not nonparametrically identifiable regardless of the number of the values the data vector can take. When k 3, there emerges a link between the variation in the data vector, and the number of identifiable subpopulations: the number of identifiable subpopulations increases as the data vector takes on additional (different) values. This points to the possibility of identifying many components even when k = 3, if the data vector has a continuously distributed element. Our identification method is constructive, and leads to an estimation strategy. It is not as efficient as the MLE, but can be used as the initial value of the optimization algorithm in computing the MLE. We also provide a sufficient condition for identifying the number of nonparametrically identifiable components, and develop a method for statistically testing and consistently estimating the number of nonparametrically identifiable components. We extend these procedures to develop a test for the number of components in binomial mixtures.
On the bifold heterogeneity problem for affect programs
Creators: name: Odoffin, Olivia Suwe
Publisher: name: No Publisher Supplied
Year: 2021

description: In this dissertation, I defend the affect program hypothesis, the proposal that emotions are governed by programs that coordinate prototypical patterns of emotional response. I respond to two heterogeneity problems for affect program—the problem of heterogeneity within an emotion type and the problem of heterogeneity across emotion types—with the ultimate goal of explaining how affect program theory can accommodate complex emotions. Any theory of emotion must be able to explain (a) how to account for the apparent regularities in emotional response among a certain subset of emotion types, the basic emotions, and (b) how complex emotions are (or are not) related to the subset of basic emotions. I argue that an account of (b) is based upon a strong version of the affect program hypothesis, and that relaxing the account of (a) opens up the possibility that affect programs can account for (b), not only explaining the basic emotions happiness, sadness, anger, disgust, fear, and surprise, but also more complex emotions, like shame, guilt, awe, horror, and composite states like ‘shame-horror-joy’ and ‘resentment-shame-annoyance-guilt’.

description: We begin with a discussion on two apparently disconnected topics - one related to nonperturbative superpotential generated from wrapping an M2-brane around a supersymmetric three cycle embedded in a G_2-manifold evaluated by the path-integral inside a path-integral approach of [1], and the other centered around the compact Calabi-Yau CY_3(3,243) expressed as a blow-up of a degree-24 Fermat hypersurface in WCP^4[1,1,2,8,12]. For the former, we compare the results with the ones of Witten on heterotic world-sheet instantons [2]. The subtopics covered in the latter include an N=1 triality between Heterotic, M- and F-theories, evaluation of RP^2-instanton superpotential, Picard-Fuchs equation for the mirror Landau-Ginsburg model corresponding to CY_3(3,243), D=11 supergravity corresponding to M-theory compactified on a `barely' G_2 manifold involving CY_3(3,243) and a conjecture related to the action of antiholomorphic involution on period integrals. We then show an indirect connection between the two topics by showing a connection between each one of the two and Witten's MQCD [3]. As an aside, we show that in the limit of vanishing "ζ", a complex constant that appears in the Riemann surfaces relevant to definining the boundary conditions for the domain wall in MQCD, the infinite series of [4] used to represent a suitable embedding of a supersymmetric 3-cycle in a G_2-mannifold, can be summed.

description: Imperfections in analog-to-digital conversion (ADC) cannot be ignored when signal digitization requirements demand both wide dynamic range and high resolution, as is the case for the Majorana Demonstrator 76Ge neutrinoless double beta decay search. Enabling the experiment's high-resolution spectral analysis and efficient pulse shape discrimination required careful measurement and correction of ADC nonlinearites. A simple measurement protocol was developed that did not require sophisticated equipment or lengthy data taking campaigns. A slope-dependent hysteresis was observed and characterized. A correction applied to digitized waveforms prior to signal processing reduced the differential and integral nonlinearites by an order of magnitude, eliminating these as dominant contributions to the systematic energy uncertainty at the double-beta decay Q value.

description: The new Keynesian Phillips curve (NKPC) restricts multivariate forecasts. I estimate and test it entirely within a panel of professional forecasts, thus using the time-series, cross-forecaster, and cross-horizon dimensions of the panel. Estimation uses 13,193 observations on quarterly US inflation forecasts since 1981. The main finding is a significantly larger weight on expected future inflation than on past inflation, a finding which also is estimated with much more precision than in the standard approach. Inflation dynamics also are stable over time, with no decline in inflation inertia from the 1980s to the 2000s. But, as in historical data, identifying the output gap is difficult.

description: We construct a covering of Culler-Vogtmann Outer space by the Teichmuller spaces of punctured surfaces. By considering the equivariant homology for the action of Out(F_n) on this covering, we construct a spectral sequence converging to the homology of Out(F_n) that has E^1 terms given by the homology of mapping class groups and groups that are, up to finite index, subgroups of mapping class groups. This spectral sequence can be seen as encoding all of the information of how the homology of Out(F_n) is related to the homology of mapping class groups and their subgroups.

description: We reconsider the electrostatic contribution to the persistence length, $\ell_e$, of a single, infinitely long charged polymer in the presence of screening. A Gaussian variational method is employed, taking $\ell_e$ as the only variational parameter. For weakly charged and flexible chains, crumpling occurs at small length scales because conformational fluctuations overcome electrostatic repulsion. The electrostatic persistence length depends on the square of the screening length, $\ell_e\simκ^{-2}$, as first argued by Khokhlov and Khachaturian by applying the Odijk-Skolnick-Fixman (OSF) theory to a string of crumpled blobs. We compare our approach to previous theoretical works (including variational formulations) and show that the result $\ell_e\simκ^{-1}$ found by several authors comes from the improper use of a cutoff at small length scales. For highly charged and stiff chains, crumpling does not occur; here we recover the OSF result and validate the perturbative calculation for slightly bent rods.

description: A computer program was modified to model the dynamics of morphogen concentrations in a developing eye of a Xenopus laevis frog. The dynamics were modelled because it is believed that the behavior of the morphogen concentrations determine how the developing eye maps to the brain. The eye in the xenophus grows as a series of rings, and thus this is the model used. The basis for the simulation are experiments done by Sullivan et al. Following the experiment, aIl eye ring is "split" in half, inverted, and then "pasted" onto a donor half. The purpose of the program is to replicate and analyze the results that were found experimentally: a graft made on a north to south axis (dorsal to ventral) produces a change in vision along the east to west axis (anterior to posterior). Four modified Gierer-Meinhardt reaction-diffusion equations are used to simulate the operation. In the second part of the research, the program was further modified and a time series analysis was done on the results. It was found that the modified Gierer-Meinhardt equations demonstrated chaotic behavior under certain conditions. The dynamics included fixed points, limit cycles, transient chaos, intermittent chaos, and strange attractors. The creation and destruction of fractal torii was found.

description: Monte Carlo evidence has made it clear that asymptotic tests based on generalized method of moments (GMM) estimation have disappointing size. The problem is exacerbated when the moment conditions are serially correlated. Several block bootstrap techniques have been proposed to correct the problem, including Hall and Horowitz (1996) and Inoue and Shintani (2006). We propose an empirical likelihood block bootstrap procedure to improve inference where models are characterized by nonlinear moment conditions that are serially correlated of possibly infinite order. Combining the ideas of Kitamura (1997) and Brown and Newey (2002), the parameters of a model are initially estimated by GMM which are then used to compute the empirical likelihood probability weights of the blocks of moment conditions. The probability weights serve as the multinomial distribution used in resampling. The first-order asymptotic validity of the proposed procedure is proven, and a series of Monte Carlo experiments show it may improve test sizes over conventional block bootstrapping.

description: We report the diversity of scroll wave chimeras in the three-dimensional (3D) Kuramoto model with inertia for N^{3} identical phase oscillators placed in a unit 3D cube with periodic boundary conditions. In the considered model with inertia, we have found patterns which do not exist in this system without inertia. In particular, a scroll ring chimera is obtained from random initial conditions. In contrast to this system without inertia, where all chimera states have incoherent inner parts, these states can have partially coherent or fully coherent inner parts as exemplified by a scroll ring chimera. Solitary states exist in the considered model as separate states or can coexist with scroll wave chimeras in the oscillatory space. We also propose a method of construction of 3D images using solitary states as solutions of the 3D Kuramoto model with inertia.

Chasing the GZK with HiRes

description: The HiRes Collaboration has recently announced preliminary measurements of the energy spectrum of ultra-high energy cosmic rays (UHECR), as seen in monocular analyses from each of the two HiRes sites. This spectrum is consistent with the existence of the GZK cutoff, as well other aspects of the energy loss processes that cause the GZK cutoff. Based on the analytic energy loss formalism of Berezinsky {\it et al.}, the HiRes spectra favor a distribution of extragalactic sources that has a similar distribution to that of luminous matter in the universe, both in its local over-density and in its cosmological evolution.

description: Nine 2-(9H-carbazol-1-yl)anilines with rings fused at the 3,4-position were acylated at the amino group with chloroacetyl, 3-chloropropanoyl, or 4-chlorobutyryl chloride, at yields of 85–99%. The resulting ω-chloroamides were exposed to potassium tert-butoxide in THF. All nine acetamides annulated exclusively at the carbazole N atom, giving benzodiazocinocarbazoles at 76–91% overall yield. The only propanamide prepared underwent α,β-elimination, giving the corresponding acrylamide at 70% overall yield. All nine butanamides annulated exclusively at the amide nitrogen, giving pyrrolidin-2-ones at 70–94% overall yield. Additionally, the 1-indanone derived carbazolylaniline followed the same annulation pattern, but the benzylic methylene group was oxidized, giving the corresponding fluorenones. The cyclohexanone-derived carbazolylaniline was also converted into a maleimide, which participated in a Diels-Alder reaction with cyclopentadiene. Attempts to replace the amino group in the starting material via diazotization were unsuccessful. Instead, a Widman-Stoermer reaction was observed, in which the diazonium group attacked the carbazole 2-position, giving the corresponding cinnoline.

description: We study several tests for the coefficient of the single right-hand-side endogenous vari- able in a linear equation estimated by instrumental variables. We show that writing all the test statistics—Student’s t, Anderson-Rubin, the LM statistic of Kleibergen and Moreira (K), and likelihood ratio (LR)—as functions of six random quantities leads to a number of interesting results about the properties of the tests under weak- instrument asymptotics. We then propose several new procedures for bootstrapping the three non-exact test statistics and also a new conditional bootstrap version of the LR test. These use more efficient estimates of the parameters of the reduced-form equation than existing procedures. When the best of these new procedures is used, both the K and conditional bootstrap LR tests have excellent performance under the null. However, power considerations suggest that the latter is probably the method of choice.

description: The search of high-order periodic orbits has been typically restricted to problems with symmetries that help to reduce the dimension of the search space. Well-known examples include reversible maps with symmetry lines. The present work proposes a new method to compute high-order periodic orbits in twist maps without the use of symmetries. The method is a combination of the parameterization method in Fourier space and a Newton-Gauss multiple shooting scheme. The parameterization method has been successfully used in the past to compute quasi-periodic invariant circles. However, this is the first time that this method is used in the context of periodic orbits. Numerical examples are presented showing the accuracy and efficiency of the proposed method. The method is also applied to verify the renormalization prediction of the residues' convergence at criticality (extensively studied in reversible maps) in the relatively unexplored case of maps without symmetries.
