description: We examine the relationship between three parameters of Type Ia supernovae (SNe~Ia): peak magnitude, rise time, and photospheric velocity at the time of peak brightness. The peak magnitude is corrected for extinction using an estimate determined from MLCS2k2 fitting. The rise time is measured from the well-observed $B$-band light curve with the first detection at least 1~mag fainter than the peak magnitude, and the photospheric velocity is measured from the strong absorption feature of Si~II~$λ$6355 at the time of peak brightness. We model the relationship among these three parameters using an expanding fireball with two assumptions: (a) the optical emission is approximately that of a blackbody, and (b) the photospheric temperatures of SNe~Ia are similar to each other at the time of peak brightness. We compare the precision of the distance residuals inferred using this physically motivated model against those from the empirical Phillips relation and the MLCS2k2 method for 47 low-redshift SNe~Ia ($0.005 < z< 0.04$) and find comparable scatter. However, SNe~Ia in our sample with higher velocities are inferred to be intrinsically fainter. Eliminating the high-velocity SNe and applying a more stringent extinction cut to obtain a "low-v-golden sample" of 22 SNe, we obtain significantly reduced scatter in the new relation, better than those of the Phillips relation and the MLCS2k2 method. After removing model peculiar velocities, our final scatter for the new relation is $0.108 \pm 0.018$~mag.

A Fast Clustering Algorithm with Application to Cosmology

description: We present a fast clustering algorithm for density countour clusters (Hartigan, 1975) that is a modified version of the Cuevas, Febrero and Fraiman (2000) algorithm. By Hartigan's definition, clusters are the connected components of a level set Sc≡{f ≥ c} where f is the probability density function. We use kernel density estimators and orthogonal series estimators to estimate f and modify the Cuevas, Febrero and Fraiman (2000) Algorithm to extract the connected components from level set estimators ^Sc≡{^f ≥ c}. Unlike the original algorithm, our method does not require an extra smoothing parameter and can use the Fast Fourier Tranform (FFT) to speed up the calculations. We show the cosmological definition of clusters of galaxies is equivalent to density contour clusters and present an application in cosmology.

description: We investigate the competition between charge-density-wave (CDW) states and a Coulomb interaction-driven topological Mott insulator (TMI) in the honeycomb extended Hubbard model. For the spinful model with on-site ($U$) and next-nearest-neighbor ($V_2$) Coulomb interactions at half filling, we find two peculiar six-sublattice charge-density-wave insulating states by using variational Monte Carlo simulations as well as the Hartree-Fock approximation. We observe that conventional ordered states always win with respect to the TMI. The ground state is given in the large-$V_2$ region by a CDW characterized by a 220200 (001122) charge configuration for smaller (larger) $U$, where 0, 1, and 2 denote essentially empty, singly occupied, and doubly occupied sites. Within the 001122-type CDW phase, we find a magnetic transition driven by an emergent coupled-dimer antiferromagnet on an effective square lattice of singly occupied sites. Possible realizations of the found states are discussed.

description: At the intersection of galactic dynamics, evolution and global structure, issues such as the relation between bars and spirals and the persistence of spiral patterns can be addressed through the characterization of the angular speeds of the patterns and their possible radial variation. The Radial Tremaine-Weinberg (TWR) Method, a generalized version of the Tremaine-Weinberg method for observationally determining a single, constant pattern speed, allows the pattern speed to vary arbitrarily with radius. Here, we perform tests of the TWR method with regularization on several simulated galaxy data sets. The regularization is employed as a means of smoothing intrinsically noisy solutions, as well as for testing model solutions of different radial dependence (e.g. constant, linear or quadratic). We test these facilities in studies of individual simulations, and demonstrate successful measurement of both bar and spiral pattern speeds in a single disk, secondary bar pattern speeds, and spiral winding (in the first application of a TW calculation to a spiral simulation). We also explore the major sources of error in the calculation and find uncertainty in the major axis position angle most dominant. In all cases, the method is able to extract pattern speed solutions where discernible patterns exist to within 20% of the known values, suggesting that the TWR method should be a valuable tool in the area of galactic dynamics. For utility, we also discuss the caveats in, and compile a prescription for, applications to real galaxies.

Directed motion and useful work from an isotropic nonequilibrium distribution

description: We demonstrate that a gas of classical particles trapped in an external asymmetric potential undergoes a quasiperiodic motion, if the temperature of its initial velocity distribution $T_{ne}$ differs from the equilibrium temperature, $T_{eq}$. The magnitude of the effect is determined by the value of $T_{ne}-T_{eq}$, and the direction of the motion is determined by the sign of this expression. The "loading'' and "unloading'' of the gas particles change directions of their motion, thereby creating a possibility of shuttle-like motion. The system works as a Carnot engine where the heat flow between kinetic and potential parts of the nonequilibrium distribution produces the useful work.

description: Background: This study examined (1) the factor structure of a depressive symptoms scale (DSS), (2) the sex and longitudinal invariance of the DSS, and (3) the predictive validity of the DSS scale during adolescence in terms of predicting depression and anxiety symptoms in early adulthood. Methods: Data were drawn from the Nicotine Dependence in Teens (NDIT) study, an ongoing prospective cohort study of 1,293 adolescents. Results: The analytical sample included 527 participants who provided complete data or had minimal missing data over follow-up. Confirmatory factor analysis revealed that an intercorrelated three-factor model with somatic, depressive, and anxiety factors provided the best fit. Further, this model was invariant across sex and time. Finally, DSS scores at Time 3 correlated significantly with depressive and anxiety symptoms measured at Time 4. Conclusions: Results suggest that the DSS is multidimensional and that it is a suitable instrument to examine sex differences in somatic, depressive, and anxiety symptoms, as well as changes in these symptoms over time in adolescents. In addition, it could be used to identify individuals at-risk of psychopathology during early adulthood.
A Dynamic Supply-Demand Model for Electricity Prices

description: We introduce a new model for electricity prices, based on the principle of supply and demand equilibrium. The model includes latent supply and demand curves, which may vary over time, and assumes that observed price/quantity pairs are obtained as the intersection of the two curves, for any particular point in time. Although the model is highly nonlinear, we explain how the particle filter can be used for model parameter estimation, and to carry out residual analysis. We apply the model in a study of Californian wholesale electricity prices over a three-year period including the crisis period during the year 2000. The residuals indicate that inflated prices do not appear to be attributable to natural random variation, temperature effects, natural gas supply effects, or plant stoppages. However, without ruling out other factors, we are unable to argue whether or not market manipulation by suppliers played a role during the crisis period.

The data and ancilla qubits of the small stellated dodecahedron code can be located on the edges resp. vertices of a small stellated dodecahedron, making this code suitable for 3D connectivity. This code encodes 8 logical qubits into 30 physical qubits (plus 22 ancilla qubits for parity check measurements) as compared to 1 logical qubit into 9 physical qubits (plus 8 ancilla qubits) for the surface code. We develop fault-tolerant parity check circuits and a decoder for this code, allowing us to numerically assess the circuit-based pseudo-threshold.

description: This paper applies conformal prediction techniques to compute simultaneous prediction bands and clustering trees for functional data. These tools can be used to detect outliers and clusters. Both our prediction bands and clustering trees provide prediction sets for the underlying stochastic process with a guaranteed finite sample behavior, under no distributional assumptions. The prediction sets are also informative in that they correspond to the high density region of the underlying process. While ordinary conformal prediction has high computational cost for functional data, we use the inductive conformal predictor, together with several novel choices of conformity scores, to simplify the computation. Our methods are illustrated on some real data examples.

description: THE TEST OF OVERIDENTIFYING restrictions of one equation in a simultaneous system proposed by Anderson and Rubin [1] and amplified by Koopmans and Hood [7] has been a source of some confusion in the literature. For instance, Liu and Breen [8] claimed that "It is ... clear that the test does not really test the null hypothesis (of zero restrictions on the endogenous and exogenous variables)" because, they thought the restrictions on the endogenous variables were included in the computation of the likelihood under the alternative hypothesis. After Fisher and Kadane [3] gave a verbal argument showing that the test is consistent over a wide class of alternatives, Liu and Breen [9] withdrew their earlier view. Nonetheless there is a problem in that generally the null hypothesis is expressed in terms of the structural form, while generally consistency is a matter of the reduced form. Our purpose is to reexamine this problem, and prove two theorems showing the equivalence of various conditions in the literature. We suggest that the null hypothesis be extended.

description: Jupyter notebooks has emerged as a standard tool for data science programming. Programs in Jupyter notebooks are different from typical programs as they are constructed by a collection of code snippets interleaved with text and visualisation. This allows interactive exploration and snippets may be executed in different order which may give rise to different results due to side-effects between snippets. Previous studies have shown the presence of considerable code duplication -- code clones -- in sources of traditional programs, in both so-called systems programming languages and so-called scripting languages. In this paper we present the first large-scale study of code cloning in Jupyter notebooks. We analyse a corpus of 2.7 million Jupyter notebooks hosted on GitHJub, representing 37 million individual snippets and 227 million lines of code. We study clones at the level of individual snippets, and study the extent to which snippets are recurring across multiple notebooks. We study both identical clones and approximate clones and conduct a small-scale ocular inspection of the most common clones. We find that code cloning is common in Jupyter notebooks -- more than 70% of all code snippets are exact copies of other snippets (with possible differences in white spaces), and around 50% of all notebooks do not have any unique snippet, but consists solely of snippets that are also found elsewhere. In notebooks written in Python, at least 80% of all snippets are approximate clones and the prevalence of code cloning is higher in Python than in other languages. We further find that clones between different repositories are far more common than clones within the same repository. However, the most common individual repository from which a Jupyter notebook contains clones is the repository in which itself resides.
Field theoretic renormalization study of reduced quantum electrodynamics and applications to the ultra-relativistic limit of Dirac liquids

description: The field theoretic renormalization study of reduced quantum electrodynamics (QED) is performed up to two loops. In the condensed matter context, reduced QED constitutes a very natural effective relativistic field theory describing (planar) Dirac liquids, e.g., graphene and graphene-like materials, the surface states of some topological insulators and possibly half-filled fractional quantum Hall systems. From the field theory point of view, the model involves an effective (reduced) gauge field propagating with a fractional power of the d'Alembertian in marked contrast with usual QEDs. The use of the BPHZ prescription allows for a simple and clear understanding of the structure of the model. In particular, in relation with the ultra-relativistic limit of graphene, we straightforwardly recover the results for both the interaction correction to the optical conductivity: $\mathcal{C}^*=(92-9π^2)/(18π)$ and the anomalous dimension of the fermion field: $γ_ψ(\barα,ξ) = 2 \barα\,(1-3ξ)/3 -16\,\left( ζ_2 N_F + 4/27 \right)\, \barα^2 + O(\barα^3)$, where $\barα = e^2/(4π)^2$ and $ξ$ is the gauge-fixing parameter.

We provide a new distance estimate to the SNR/pulsar system by analyzing the HI and $^{13}$CO maps, the HI emission and absorption spectra, and the $^{13}$CO emission spectrum of Kes 75. No absorption features at negative velocities strongly argue against the widely-used large distance of 19 to 21 kpc for Kes 75, and show that Kes 75 is within the Solar circle, i.e. a distance $d

description: La reducción constante del número de conscriptos ha generado un desafío para el Ejército de Colombia. Entre 2017 y 2021, esta disminución promedió un 12,6% anual (Comando de Reclutamiento, Control, Reservas y Movilización, 2021). Esta tendencia a la baja no muestra indicios de revertirse en los años futuros, y se espera una reducción del 14,2% para el año 2028, lo que afectará tanto el enfoque estratégico de las fuerzas armadas como los componentes operacionales básicos, como la táctica. Este problema se origina por varias causas identiﬁcadas en un análisis contextual. En primer lugar, las exoneraciones limitan la incorporación de conscriptos que desean vincularse y solucionar su situación militar. En segundo lugar, el número de jóvenes hombres entre 18 y 24 años que no estudian ni trabajan ha disminuido desde 2007, con una tendencia a la baja que se intensiﬁcó en los años 2021 y 2022 (DANE, 2022). En tercer lugar, las estrategias de reclutamiento no se ajustan a los contextos cambiantes, lo que ha llevado a una percepción errada sobre la importancia y los objetivos del servicio militar en el fortalecimiento del sistema de seguridad y defensa nacional. Por último, no se han realizado estudios institucionales que analicen los datos y comprendan las tendencias nacionales, regionales e internacionales que podrían mejorar y optimizar las estrategias de reclutamiento.
description: The constant reduction in the number of conscripts has created a challenge for the Colombian Army. Between 2017 and 2021, this decline averaged 12.6% per year (Recruitment, Control, Reserves and Mobilization Command, 2021). This downward trend shows no signs of reversing in future years, and a reduction of 14.2% is expected for the year 2028, which will affect both the strategic focus of the armed forces and basic operational components, such as tactics. This problem originates from several causes identiﬁed in a contextual analysis. In the ﬁrst place, the exemptions limit the incorporation of conscripts who wish to join and solve their military situation. Second, the number of young men between the ages of 18 and 24 who neither study nor work has decreased since 2007, with a downward trernd that intensiﬁed in 2021 and 2022 (DANE, 2022). Third, recruitment strategies do not adjust to changing contexts, which has led to a misperception about the importance and objectives of military service in strengthening the national security and defense system. Finally, there have been no institutional studies that analyze the data and understand national, regional, and international trends that could improve and optimize recruitment strategies.

description: The state of electrons injected onto the surface of the Fermi sea depends on temperature. The state is pure at zero temperature and is mixed at finite temperature. In the case of a single-electron injection, such a transformation can be detected as a decrease in shot noise with increasing temperature. In the case of a multi-electron injection, the situation is more subtle. The mixedness helps the development of quantum-mechanical exchange correlations between injected electrons, even if such correlations are absent at zero temperature. These correlations enhance the shot noise, what in part counteracts the reduction of noise with temperature. Moreover, at sufficiently high temperatures, the correlation contribution to noise predominates over the contribution of individual particles. As a result, in the system of $N$ electrons, the apparent charge (which is revealed via the shot noise) is changed from $e$ at zero temperature to $Ne$ at high temperatures. It looks like the exchange correlations glue up electrons into one particle of total charge and energy. This point of view is supported by both charge noise and heat noise. Interestingly, in the macroscopic limit, $N\to \infty$, the correlation contribution completely suppresses the effect of temperature on noise.

A Class of Generalized Long-Memory Time Series Models

Publisher: name: Carnegie Mellon University
Year: 2002
Subjects: subject: Probability
subject: Statistics

description: This paper introduces a family of ``generalized long-memory time series models'', in which observations have a specified conditional distribution, given a latent Gaussian fractionally integrated autoregressive moving average (ARFIMA) process. The observations may have discrete or continuous distributions (or a mixture of both). The family includes existing models such as ARFIMA models themselves, long-memory stochastic volatility models, long-memory censored Gaussian models, and others. Although the family of models is flexible, the latent long-memory process poses problems for analysis. Therefore we introduce a Markov chain Monte Carlo sampling algorithm and develop a set of recursions which make it feasible. This makes it possible, among other things, to carry out exact likelihood-based analysis of a wide range of non-Gaussian long-memory models without resorting to the use of likelihood approximations. The procedure also yields predictive distributions that take into account model parameter uncertainty. The approach is demonstrated in two case studies.

En efecto, el proceso de constitucionalidad abstracto se encuentra regulado en el Decreto 2067 de 1991 y el procedimiento de tutela principalmente en el Decreto 25 91 de 1991. Dichas normativas diseñaron procedimientos expeditos, informales, participativos, y a pesar de que se rigen por el principio dispositivo para el inicio del asunto (salvo el control constitucional automático de algunas leyes) el dominio de la actividad procesal corresponde a los jueces, pues no solo tienen amplias facultades para impulsar los procesos, decretar y practicar pruebas, sino también están autorizados a fallar extra o ultra petita.

description: In light-front dynamics, form factors are traditionally computed with the "good current" $J^+$ within the Drell-Yan frame $q^+=0$. Due to truncations imposed in practical calculations, the from factor may acquire frame dependence, which is often neglected. In this work, we explore the form factors in more general frames, preserving the boost covariance. We find the frame dependence of the elastic form factors for mesons is small in basis light-front holography and related models with two-body Fock space truncation. We suggest to use the difference between form factor results from Drell-Yan frame and the "longitudinal frame" as a metric for the violation of the Lorentz symmetry due to Fock space truncation.

description: Abstract

Climate change is a primary driver in accelerating certain regions' Dengue Hemorrhagic Fever (DHF) pandemic. Key climate factors, such as temperature, humidity, and rainfall, significantly contribute to mosquito vectors' spread and infection of the dengue virus. This study was conducted in Tobelo City, North Halmahera Regency, using data from the “DHF Cases and Climate Factors over the Last 5 Years in Tobelo City”. The climate factors examined were rainfall, humidity, and air temperature. A path analysis was utilized to observe the relationship between DHF cases and Climate Factors (rainfall, air humidity, air temperature) in Tobelo City. The climate factors studied are  rainfall, humidity, and air temperature. Path analysis was used to see the relationship between dengue fever cases and climate factors (rainfall, air humidity, air temperature) in Tobelo City. The research results show that rainfall (X2) has a direct effect on the incidence of dengue fever (Y1) through temperature (3X) = 0.0816, with a significant contribution of = 0.8046. Humidity has no direct effect on dengue fever (Y) incidence. Meanwhile, indirectly through temperature (X3) = 0.028. There was a positive relationship between humidity and temperature in dengue cases, but the relationship was fragile (29.8%).

Dynamical properties of the $S=\frac{1}{2}$ random Heisenberg chain

description: We use numerical techniques to study dynamical properties at finite temperature ($T$) of the Heisenberg spin chain with random exchange couplings, which realizes the random singlet (RS) fixed point in the low-energy limit. Specifically, we study the dynamic spin structure factor $S(q,ω)$, which can be probed directly by inelastic neutron scattering experiments and, in the limit of small $ω$, in nuclear magnetic resonance (NMR) experiments through the spin-lattice relaxation rate $1/T_1$. Our work combines three complementary methods: exact diagonalization, matrix-product-state algorithms, and stochastic analytic continuation of quantum Monte Carlo results in imaginary time. Unlike the uniform system, whose low-energy excitations at low $T$ are restricted to $q$ close to $0$ and $π$, our study reveals a continuous narrow band of low-energy excitations in $S(q,ω)$, extending throughout the Brillouin zone. Close to $q=π$, the scaling properties of these excitations are well captured by the RS theory, but we also see disagreements with some aspects of the predicted $q$-dependence further away from $q=π$. Furthermore we find spin diffusion effects close to $q=0$ that are not contained within the RS theory but give non-negligible contributions to the mean $1/T_1$. To compare with NMR experiments, we consider the distribution of the local $1/T_1$ values, which is broad, approximately described by a stretched exponential. The mean value first decreases with $T$, but starts to increase and diverge below a crossover temperature. Although a similar divergent behavior has been found for the static uniform susceptibility, this divergent behavior of $1/T_1$ has never been seen in experiments. Our results show that the divergence of the mean $1/T_1$ is due to rare events in the disordered chains and is concealed in experiments, where the typical $1/T_1$ value is accessed.

A Bayesian Hierarchical method for fitting multiple health endpoints in a toxicity study

description: Bayesian hierarchical models are built to fit multiple health endpoints from a dose-response study of a toxic chemical, perchlorate. Perchlorate exposure results in iodine uptake inhibition in the thyroid, with health effects manifested by changes in blood hormone concentrations and histopathological effects on the thyroid. We propose linked empirical models to fit blood hormone concentration and thyroid histopathology data for rats exposed to perchlorate in the 90-day study of Springborn Laboratory Inc. (1998), based upon the assumed toxicological relationships between dose and the various endpoints. All of the models are fit in a Bayesian framework, and predictions about each endpoint in response to dose are simulated based on the posterior predictive distribution. A hierarchical model tries to exploit possible similarities between different combinations of sex and exposure duration, and it allows us to produce more stable estimates of dose-response curves. We also illustrate how the hierarchical model allows us to address additional questions that arise after the analysis.
Null Infinity and Unitary Representation of The Poincare Group

description: Following Pasterski-Shao-Strominger we construct a new basis of states in the single-particle Hilbert space of massless particles as a linear combination of standard Wigner states. Under Lorentz transformation the new basis states transform in the Unitary Principal Continuous Series representation. These states are obtained if we consider the little group of a null momentum \textit{direction} rather than a null momentum. The definition of the states in terms of the Wigner states makes it easier to study the action of space-time translation in this basis. We show by taking into account the effect of space-time translation that \textit{the dynamics of massless particles described by these states takes place completely on the null-infinity of the Minkowski space}. We then second quantize the theory in this basis and obtain a unitary manifestly Poincare invariant (field) theory of free massless particles living on null-infinity. The null-infinity arises in this case purely group-theoretically without any reference to bulk space-time. Action of BMS on massless particles is natural in this picture. As a by-product we generalize the conformal primary wave-functions for massless particles in a way which makes the action of space-time translation simple. Using these wave-functions we write down a modified Mellin(-Fourier) transformation of the S-matrix elements. The resulting amplitude is Poincare covariant. Under Poincare transformation it transforms like products of primaries of inhomogeneous $SL(2,\mathbb{C})$ ($ISL(2,\mathbb{C})$) inserted at various points of null-infinity. $ISL(2,\mathbb{C})$ primaries are defined in the paper.

Tachyon-Free Non-Supersymmetric Strings on Orbifolds

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

description: We discuss tachyon-free examples of (Type IIB on) non-compact non-supersymmetric orbifolds. Tachyons are projected out by discrete torsion between orbifold twists, while supersymmetry is broken by a Scherk-Schwarz phase (+1/-1 when acting on space-time bosons/fermions) accompanying some even order twists. The absence of tachyons is encouraging for constructing non-supersymmetric D3-brane gauge theories with stable infrared fixed points. The D3-brane gauge theories in our orbifold backgrounds have chiral N = 1 supersymmetric spectra, but non-supersymmetric interactions.

A Bayesian Approach to Designing U.S. Census Sampling for Reapportionment
Creators: name: Kadane, Joseph B.
Publisher: name: Carnegie Mellon University
Year: 1995
Subjects: subject: Probability
subject: Statistics

description: This article proposes a design criterion for sampling in conjuction with the U.S. censuses of 2000 and beyond. Since reapportionment of Congress is the constitutional basis of the census, the loss function used here minimizes apportionment errors in a certain sense. This leads to a stochastic modification of the Hill (equal proportions) method of apportionment now used. If the sampling in the census is designed to achieve minimum constant coefficient of variation of state shares of the national population, the use of the proposed “single-number” census will result in the same apportionment as would have been obtained using the proposed loss function.
Constraints on the correlation between QSO luminosity and host halo mass from high-redshift quasar clustering

description: Recent measurements of high-redshift QSO clustering from the Sloan Digital Sky Survey indicate that QSOs at z~4 have a bias b~14. We find that this extremely high clustering amplitude, combined with the corresponding space density, constrains the dispersion in the L-Mhalo relation to be less than 50% at 99% confidence for the most conservative case of a 100% duty cycle. This upper limit to the intrinsic dispersion provides as strong a constraint as current upper limits to the intrinsic dispersion in the local M_BH-sigma relation and the ratio of bolometric to Eddington luminosity of luminous QSOs.
