description: Motivated by some previous work on fermions on random lattices and by suggestions that impurities could trigger parity breaking in 2d crystals, we have analyzed the spectrum of the Dirac equation on a two dimensional square lattice where sites have been removed randomly --- a doped lattice. We have found that the system is well described by a sine-Gordon action. The solitons of this model are the lattice fermions, which pick a quartic interaction due to the doping and become Thirring fermions. They also get an effective mass different from the lagrangian mass. The system seems to exhibit spontaneous symmetry breaking, exactly as it happens for a randomly triangulated lattice. The associated ``Goldstone boson" is the sine-Gordon scalar. We argue, however, that the peculiar behaviour of the chiral condensate is due to finite size effects.

description: A lattice calculation of the pseudoscalar decay constant of heavy-light mesons is reported. Results are obtained (in the quenched approximation) from lattices at $β=6.3$ through a procedure that interpolates between the static approximation of Eichten and the conventional ("heavy" Wilson fermion) method. The previously observed discrepancy between these two approaches has been resolved: we find the scaling quantity $f\sqrt{M}$ to be significantly smaller than previous calculations had indicated ({\it e.g.} at $β=6.0$); in addition, we discuss a modification which is required in normalizing the conventional amplitude to correct for large-$am$ lattice errors. This change guarantees that $f\sqrt{M}$ will smoothly approach its value in the static limit. From the numerical interpolation of the static and intermediate-mass results, we find, in units of MeV, $f_B=187(10)\pm34\pm15$, $f_{B_s}=207(9)\pm34\pm22$, $f_D=208(9)\pm35\pm12$ and $f_{D_s}=230(7)\pm30\pm18$, where the first error is statistical and the second two are estimates of systematics due to 1) fitting and large-$am$ effects and 2) scaling. In addition, using lattices at $β=6.3$, $β=6.0$ and $β=5.7$ and extrapolating to the limit of zero lattice spacing, we have computed $f_K/f_π= 1.08\pm.03\pm.08$ in the quenched approximation.

description: To achieve high rate of Multi-Giga-bits-per-second for multimedia applications at personal area level, 60 GHz communication technologies are most potential candidates. Due to some special characteristics of 60 GHz band of frequencies and use of multiple directional antennas,the network level and user level throughput can be increased tremendously by identifying and scheduling the non interfering transmission requests for concurrent transmissions. Instead of direct communication between source and destination, by traversing the traffic flow on optimum path (consists of light weight multiple-relying-hops), can further increase the throughput and balances the load condition across the network. In this paper we present a scheduling scheme for concurrent transmission of non interfering transmission requests on instantaneous optimum path. Performance of scheme is investigated for different path loss exponents.

description: Consumers are often able to choose how often to consume the things they enjoy. The research presented here suggests that consumers tend to consume too rapidly, growing tired of initially well-liked stimuli such as a favorite snack (Experiments 1 and 4) or an enjoyable video game (Experiments 2 and 3) more quickly than they would if they slowed consumption. The results also suggest that this because of an underestimation of the extent to which breaks reset adaptation. The results present a paradox: Participants who chose their own rate of consumption enjoyed the stimulus less than participants who had a slower rate of consumption chosen for them.

description: The exclusion statistics of two complementary sets of quasiparticles, generated from opposite ends of the spectrum, are identified for Ising chains with spin s=1/2,1. In the s=1/2 case the two sets are antiferromagnetic domain walls (solitons) and ferromagnetic domains (strings). In the s=1 case they are soliton pairs and nested strings, respectively. The Ising model is equivalent to a system of two species of solitons for s=1/2 and to a system of six species of soliton pairs for s=1. Solitons exist on single bonds but soliton pairs may be spread across many bonds. The thermodynamics of a system of domains spanning up to $M$ lattice sites is amenable to exact analysis and shown to become equivalent, in the limit M -> infinity, to the thermodynamics of the s=1/2 Ising chain. A relation is presented between the solitons in the Ising limit and the spinons in the XX limit of the s=1/2 XXZ chain.

description: We investigate the influence of the measure in the path integral for Euclidean quantum gravity in four dimensions within the Regge calculus. The action is bounded without additional terms by fixing the average lattice spacing. We set the length scale by a parameter $β$ and consider a scale invariant and a uniform measure. In the low $β$ region we observe a phase with negative curvature and a homogeneous distribution of the link lengths independent of the measure. The large $β$ region is characterized by inhomogeneous link lengths distributions with spikes and positive curvature depending on the measure.

description: Software-defined networking (SDN) is a new paradigm that allows developing more flexible network applications. SDN controller, which represents a centralized controlling point, is responsible for running various network applications as well as maintaining different network services and functionalities. Choosing an efficient intrusion detection system helps in reducing the overhead of the running controller and creates a more secure network. In this study, we investigate the performance of the well-known anomaly-based intrusion detection approaches in terms of accuracy, false alarm rate, precision, recall, f1-measure, area under ROC curve, execution time and Mc Nemar's test. Precisely, we focus on supervised machine-learning approaches where we use the following classifiers: Decision Trees (DT), Extreme Learning Machine (ELM), Naive Bayes (NB), Linear Discriminant Analysis (LDA), Neural Networks (NN), Support Vector Machines (SVM), Random Forest (RT), K Nearest-Neighbour (KNN), AdaBoost, RUSBoost, LogitBoost and BaggingTrees where we employ the well-known NSL-KDD benchmark dataset to compare the performance of each one of these classifiers.

Conversely, ICN type of cache networks has distinctive features e.g, contents popularity, usability time of content and other factors inflicts some diverse requirements for cache eviction policies. In this paper we defined four important characteristics of a suitable eviction policy for ICN. We analysed well known eviction policies in view of defined characteristics. Based upon analysis we propose a new eviction scheme which is well suitable for ICN type of cache networks.

description: As a first step towards constructing chiral models on the lattice with staggered fermions, we study a U(1) model with axial-vector coupling to an external gauge field in two dimensions. In our approach gauge invariance is broken, but it is restored in the classical continuum limit. We find that the continuum divergence relations for the vector and axial-vector currents are reproduced, up to contact terms, which we determine analytically. The current divergence relations are also studied numerically for smooth external gauge fields with topological charge zero. We furthermore investigate the effect of fluctuating gauge transformations and of gauge configurations with non-trivial topological charge.

description: We propose an estimation procedure for linear functionals based on Gaussian model selection techniques. We show that the procedure is adaptive, and we give a non asymptotic oracle inequality for the risk of the selected estimator with respect to the $\mathbb{L}_p$ loss. An application to the problem of estimating a signal or its $r^{th}$ derivative at a given point is developed and minimax rates are proved to hold uniformly over Besov balls. We also apply our non asymptotic oracle inequality to the estimation of the mean of the signal on an interval with length depending on the noise level. Simulations are included to illustrate the performances of the procedure for the estimation of a function at a given point. Our method provides a pointwise adaptive estimator.

description: We investigate the use of two types of non-local (``smeared'') sources for quark propagators in quenched lattice QCD at $β=6.0$ using Wilson fermions at $κ=0.154$ and $0.155$. We present results for the hadron mass spectrum, meson decay constants, quark masses, the chiral condensate and the quark distribution amplitude of the pion. The use of smeared sources leads to a considerable improvement over previous results. We find a disturbing discrepancy between the baryon spectra obtained using Wuppertal and wall sources. We find good signals in the ratio of correlators used to calculate the quark mass and the chiral condensate and show that the extrapolation to the chiral limit is smooth.

description: Nested sampling is an increasingly popular technique for Bayesian computation, in particular for multimodal, degenerate problems of moderate to high dimensionality. Without appropriate settings, however, nested sampling software may fail to explore such posteriors correctly; for example producing correlated samples or missing important modes. This paper introduces new diagnostic tests to assess the reliability both of parameter estimation and evidence calculations using nested sampling software, and demonstrates them empirically. We present two new diagnostic plots for nested sampling, and give practical advice for nested sampling software users in astronomy and beyond. Our diagnostic tests and diagrams are implemented in nestcheck: a publicly available Python package for analysing nested sampling calculations, which is compatible with output from MultiNest, PolyChord and dyPolyChord.

description: Extended theories of gravity have gathered a lot of attention over the last years, for they not only provide an excellent framework to describe the inflationary era but also yields an alternative to the elusive and mysterious dark energy. Among the different extended theories of gravity, on this work we focus on metric $f(R)$ theories. In addition, it is well known that if the late-time acceleration of the universe is stronger than the one induced by a cosmological constant then some future cosmic singularities might arise, being the Big Rip the most virulent one. Following this reasoning, on this work, we analyse the Big Rip singularity in the framework of $f(R)$ quantum geometrodynamics. Invoking the DeWitt criterium, i. e. that the wave function vanishes at the classical singularity, we proof that a class of solutions to the Wheeler-DeWitt equation fulfilling this condition can be found. Therefore, this result hints towards the avoidance of the Big Rip in metric $f(R)$ theories of gravity.

We formulate the notion of ``species permutation'' symmetry of the $N$ abelian projection fields and discuss its consequences for cross-species correlators. We show that at large $N$ cross-species interactions are ${1\over N}$ suppressed relative to same-species interactions. Numerical simulations at $N=3$ support our symmetry arguments and reveal the existence of inter-species interactions of size ${\cal O\/}\bigl({1\over N-1}\bigr)$ as analytically predicted.

description: The effect of the exchange interaction on the vibrational properties and on the electron-phonon coupling were investigated in several recent works. In most of the case, exchange tends to enhance the electron-phonon interaction, although the motivations for such behaviour are not completely understood. Here we consider the class of weakly doped two-dimensional multivalley semiconductors and we demonstrate that a more global picture emerges. In particular we show that in these systems, at low enough doping, even a moderate electron-electron interaction enhances the response to any perturbation inducing a valley polarization. If the valley polarization is due to the electron-phonon coupling, the electron-electron interaction results in an enhancement of the superconducting critical temperature. We demonstrate the applicability of the theory by performing random phase approximation and first principles calculations in transition metal chloronitrides. We find that exchange is responsible for the enhancement of the superconducting critical temperature in Li$_x$ZrNCl and that much larger T$_c$s could be obtained in intercalated HfNCl if the synthesis of cleaner samples could remove the Anderson insulating state competing with superconductivity.

description: Transportation requires large amounts of capital in fixed facilities such as roads, tracks, or canals. Inland waterway transport is unique among modes, since it neither owns its right-of-way nor pays taxes to support its construction and maintenance. Although user charges are widely employed to recover the costs of publicly provided investments, proper theoretical foundation has not been made for their application to inland waterway transport. In this paper we shall provide this foundation focusing on efficiency of allocation of resources, on equity of taxation, and on administration simplicity of each toll scheme. §1 of this paper presents the criteria to be used in evaluating waterway user charges. §2 appraises possible alternative tolls and estimates the rates that would be needed to recover current expenditures. A combination of toll schemes (segment tolls, locking fees, and congestion tolls) are argued to be economically and politically feasible and to dominate fuel taxes and license fees. The Appendix presents an example of the benefits and costs of waterway expansion and a test of the predictive power of the queueing model.
Frontal cortical asymmetry, high-frequency heart rate variability, and distress psychopathology among undergraduates who experienced trauma
Creators: name: Fedorenko, Erick J.
Publisher: name: No Publisher Supplied
Year: 2023

description: Exposure to traumatic events can increase the likelihood of developing distress psychopathology (i.e., depression, anxiety disorders, and PTSD) and young adulthood represents a critical window during which these disorders often develop. Dysregulations in two processes might contribute to the development of distress psychopathology: emotion regulation (which can be assessed using high frequency heart rate variability [HF-HRV] via EKG) and avoidance motivation (which can be assessed using frontal cortical asymmetry via EEG). One-hundred eighteen (118) college students were recruited, baseline HF-HRV was assessed, and frontal cortical asymmetry was assessed before and after a personally relevant laboratory stressor. Affect in response to the stressor and depressive, anxiety, and PTSD symptoms were assessed using self-report measures. Contrary to our hypotheses, greater baseline HF-HRV predicted greater post-stressor negative affect, less left-hemisphere post-stressor neural activity was associated with fewer PTSD symptoms, and greater pre-stressor frontal cortical asymmetry was associated with greater distress psychopathology assessed as a higher-order latent factor. Consistent with our hypotheses, there was a nonsignificant trend towards greater post-stressor frontal cortical asymmetry predicting fewer depressive symptoms and a nonsignificant trend towards less post-stressor left-sided frontal neural activity predicting greater anxiety symptoms. These findings raise questions regarding the roles of HF-HRV and frontal cortical asymmetry in distress psychopathology. We discuss the implications for clinical science research utilizing these psychophysiological tools, the benefits of multiple measures of physiology and psychopathology (including use of both symptom-specific measures and measures of high-order latent factors), and the limitations of the current study.

description: Extracting the proton charge radius from electron scattering data requires determining the slope of the charge form factor at $Q^2$ of zero. But as experimental data never reach that limit, numerous methods for making the extraction have been proposed, though often the functions are determined after seeing the data which can lead to confirmation bias. To find functional forms that will allow for a robust extraction of the input radius for a wide variety of functional forms in order to have confidence in the extraction from upcoming low $Q^2$ experimental data such as the Jefferson Lab PRad experiment, we create a general framework for inputting form-factor functions as well as various fitting functions. The input form factors are used to generate pseudo-data with fluctuations intended to mimic the binning and random uncertainty of a given set of real data. All combinations of input functions and fit functions can then be tested repeatedly against regenerated pseudo-data. Since the input radius is known, this allows us to find fit functions that are robust for radius extractions in an objective fashion. For the range and uncertainty of the PRad data, we find that a two-parameter rational function, a two-parameter continued fraction and the second order polynomial expansion of $z$ can extract the input radius regardless of the input charge form factor function that is used. We have created an easily expandable framework to search for functional forms that allow for a robust extraction of the radius from a given binning and uncertainty of pseudo-data generated from a wide variety of trial functions. This method has enabled a successful search for the best functional forms to extract the radius from the upcoming PRad data and can be used for other experiments.

Subjects: Early Marriage, Girl-child, Enrollment, Retention and Progression\

description: This study investigated the Influence of Early Marriages on Girl-Child Enrollment, Retention and Progression in Secondary Schools in Nigeria. Descriptive survey research was adopted for this study. The target population was the parents in Nigeria. The stratified random sampling technique was used to select five hundred and ninety-nine (599) respondents for the study. Instrument titled Girl-child Enrollment, Retention and Progression Questionnaire (GERP-Q) was used to collect data for the study. The instrument yielded a reliability index value of 0.81. Descriptive statistics such as frequency count, percentages, mean score, and standard deviation were used to analyse the research questions while inferential statistical tools such as t-test was used to test the hypothesis at 0.05 level of significant. The study revealed that religious beliefs, ignorance, poverty among others were the factors responsible for early marriage of the girl-child in secondary schools in Nigeria. The study further revealed that early marriage has negative influence on girl-child school enrollment, retention and progression. This study therefore recommended that there should be public enlightenment campaign and sensitization to Nigerian parents about the importance of girl - child education. These should include workshops, seminars, posters, handbills, radio and television jingles this effort should be irrespective of gender or location

description: Transportation requires large amounts of capital in fixed facilities such as roads, tracks, or canals. Inland waterway transport is unique among modes, since it neither owns its right-of-way nor pays taxes to support its construction and maintenance. Although user charges are widely employed to recover the costs of publicly provided investments, proper theoretical foundation has not been made for their application to inland waterway transport. In this paper we shall provide this foundation focusing on efficiency of allocation of resources, on equity of taxation, and on administration simplicity of each toll scheme. Section 1 of this paper presents the criteria to be used in evaluating waterway user charges. Section 2 appraises possible alternative tolls and estimates the rates that would be needed to recover current expenditures. A combination of toll schemes (segment tolls, locking fees, and congestion tolls) are argued to be economically and politically feasible and to dominate fuel taxes and license fees. The Appendix presents an example of the benefits and costs of waterway expansion and a test of the predictive power of the queueing model.

description: The factorization theorem for organizing multiple electroweak boson emissions at future colliders with energy far above the electroweak scale is formulated. Taking the inclusive muon-pair production in electron-positron collisions as an example, we argue that the summation over isospins is demanded for constructing the universal distributions of leptons and gauge bosons in an electron. These parton distributions are shown to have the same infrared structure in the phases of broken and unbroken electroweak symmetry, an observation consistent with the Goldstone Equivalence Theorem. The electroweak factorization of processes involving protons is sketched, with an emphasis on the subtlety of the scalar distributions.

description: The study examines the impact of institutional quality on human capital development in Nigeria: 1990-2024. Thestudy was anchored on the endogenous growth model using the OLS estimator to empirically determine the impact of theexplanatory variables on the dependent variable. The data series of human capital development (HCD), regulatory quality (RQ),corruption (CPI) are stationary after the first difference, while economic growth (GDP) is stationary at level. The result of findingsrevealed that Regulatory quality has a negative and statistically significant impact on human capital development in Nigeria. Inaddition, Corruption has an insignificant impact on human capital development. GDP, used here as a proxy for economic growthhas a significant negative impact on human capital development. The study recommends that policymakers should, therefore,conduct a thorough review of regulatory practices affecting educational institutions, healthcare delivery, and workforce trainingprograms. Anti-corruption bodies should implement stricter monitoring mechanisms to prevent the diversion of resources meantfor human development sectors. Finally, government should prioritize public expenditure on education, healthcare, andvocational training, ensuring that growth-related revenues are channeled toward the sectors most critical to human development.

description: We investigate the Su-Schrieffer-Heeger model in presence of an injection and removal of particles, introduced via a master equation in Lindblad form. It is shown that the dynamics of the density matrix follows the predictions of calculations in which the gain and loss are modeled by complex $\mathcal{PT}$-symmetric potentials. In particular it is found that there is a clear distinction in the dynamics between the topologically different cases known from the stationary eigenstates.

The secular tidal disruption of stars by low-mass Super Massive Black Holes secondaries in galactic nuclei

description: Stars passing too close to a super massive black hole (SMBH) can produce tidal disruption events (TDEs). Since the resulting stellar debris can produce an electromagnetic flare, TDEs are believed to probe the presence of single SMBHs in galactic nuclei, which otherwise remain dark. In this paper, we show how stars orbiting an IMBH secondary are perturbed by an SMBH primary. We find that the evolution of the stellar orbits are severely affected by the primary SMBH due to secular effects and stars orbiting with high inclinations with respect to the SMBH-IMBH orbital plane end their lives as TDEs due to Kozai-Lidov oscillations, hence illuminating the secondary SMBH/IMBH. Above a critical SMBH mass of $\approx 1.15 \times 10^8$ M$_{\odot}$, no TDE can occur for typical stars in an old stellar population since the Schwarzschild radius exceeds the tidal disruption radius. Consequently, any TDEs due to such massive SMBHs will remain dark. It follows that no TDEs should be observed in galaxies with bulges more massive than $\approx 4.15\times 10^{10}$ M$_{\odot}$, unless a lower-mass secondary SMBH or IMBH is also present. The secular mechanism for producing TDEs considered here therefore offers a useful probe of SMBH-SMBH/IMBH binarity in the most massive galaxies. We further show that the TDE rate can be $\approx 10^{-4}-10^{-3}$ yr$^{-1}$, and that most TDEs occur on $\approx 0.5$ Myr. Finally, we show that stars may be ejected with velocities up to thousands of km s$^{-1}$, which could contribute to the observed population of Galactic hypervelocity stars.
