description: Kinetic Alfvén waves (KAWs) are the short-wavelength extension of the MHD Alfvén-wave branch in the case of highly-oblique propagation with respect to the background magnetic field. Observations of space plasma show that small-scale turbulence is mainly KAW-like. We apply two theoretical approaches, collisional two-fluid theory and collisionless kinetic theory, to obtain predictions for the KAW polarizations depending on $β_\mathrm{p}$ (the ratio of the proton thermal pressure to the magnetic pressure) at the ion gyroscale in terms of fluctuations in density, bulk velocity, and pressure. We perform a wavelet analysis of MMS magnetosheath measurements and compare the observations with both theories. We find that the two-fluid theory predicts the observations better than kinetic theory, suggesting that the small-scale KAW-like fluctuations exhibit a fluid-like behavior in the magnetosheath although the plasma is weakly collisional. We also present predictions for the KAW polarizations in the inner heliosphere that are testable with Parker Solar Probe and Solar Orbiter.

Mathematical modelling of complete recessive lethals: Adaptive dynamics across varying genetic and population structures
Creators: name: La Rocca, Luis Aniello
Publisher: name: Universitäts- und Landesbibliothek Bonn
Year: 2024
Subjects: subject: ddc:510

description: The study of recessive lethal diseases in populations presents significant challenges, from estimating key parameters - such as the number of genes involved and the mutation rates driving genetic degeneration - to understanding the increased prevalence of autosomal recessive intellectual disorders (ARID) in the offspring of consanguineous unions. To address these challenges, we developed a mathematical model based on a diploid individual-based framework of adaptive dynamics. This model allowed us to make several important discoveries.
 First, we showed that the higher disease burden for ARID observed in consanguineous unions is a transient phenomenon associated with rapidly expanding population sizes. This finding highlights the need for widespread carrier screening, as the drop in prevalence in randomly mating populations is associated with an increased mutation burden.
 Second, we extended the drift-barrier hypothesis, which states that the ability of natural selection to refine traits is limited by genetic drift. We introduced a new parameter - the recessive gene count. We found that populations with a higher gene count face a similar barrier to that imposed by an increased mutation rate. In addition, our analysis provides a new perspective on Muller’s ratchet, a classic concept in population genetics that describes the irreversible accumulation of deleterious mutations in the absence of recombination. Our results show how mutations accumulate rapidly after a long period of stability, and how the population finds its way back to stability after the emergence of clusters of highly correlated genes.
 Finally, we have implemented a simulation framework based on Gillespie’s algorithm, which allows exact stochastic simulations of our model. This framework permits the study of the dynamics of complex interacting systems. The tool is flexible, scalable, and designed to facilitate further studies.

description: The genus Hepatozoon is the most diversified and prevalent of all hemogregarine genera, which leads to a range of taxonomic challenges. Under-sampling and missing molecular data from rat-originating Hepatozoon muris, the type species of the genus Hepatozoon, complicated all efforts of systematic revision of individual subclades. To clarify the taxonomy of Hepatozoon at the genus level and to restrict the usage of this generic name to a particular clade of hemogregarines, we analysed 18S rDNA sequences of Hepatozoon from three species of rats from two isolated island populations. To assess the genetic variability, we analysed complete mitochondrial genome sequences of the two closely related isolates. Phylogenetic analyses revealed the position of both closely related Hepatozoon genotypes within the 18S rDNA clade including rodent/amphibian/reptile sequences, seriously challenging the validity of the previously proposed genus Bartazoon.
MATHICSE Technical Report : Effective models for long time wave propagation in locally periodic media
Creators: name: Abdulle, Assyr
name: Pouchon, Timothée Noé
Publisher: name: Écublens, MATHICSE
Year: 2019

description: A family of effective equations for the wave equation in locally periodic media over long time is derived. In particular, explicit formulas for the effective tensors are provided. To validate the derivation, an a priori error estimate between the effective solutions and the original wave is proved. As the dependence of the estimate on the domain is explicit, the result holds in arbitrarily large periodic hypercube. This constitutes the first analysis for the description of long time effects for the wave equation in locally periodic media. Thanks to this result, the long time a priori error analysis of the numerical homogenization method presented in [A. Abdulle and T. Pouchon, SIAM J. Numer. Anal., 54, 2016, pp. 1507–1534] is generalized to the case of a locally periodic tensor.

description: We propose a phenomenological three component model describing the decay amplitude of the process $D_{s}^{+} \ra 3π$. The first component is a constant background, the second one is a Breit-Wigner amplitude associated to a quasi two-body $f_{0}(980) π^{+}$ state and the third one another Breit-Wigner amplitude corresponding to a possible quasi two-body $ρ(770) π$ state. We show that it is possible to reproduce the observed total rate for $D_{s}^{+} \ra π^{+}π^{+}π^{-}$ as well as the two other measured branching ratios for the non resonant part and the resonant $f_{0}π^{+}$ one. Implication of the $ρπ^{+}$ state, of which an experimental limit has been given, is discussed. An upper bound in the 10 MeV range for the decay constant $f_{π'}$ of the $π(1300)$ meson is obtained . Predictions are given for the $D_{s}^{+} \ra π^{0}π^{0}π^{+}$ rate as well as for the $π^{+}$ and $π^{-}$ ($π^{0}$ and $π^{+}$) energy distributions for these two decay modes $D_{s}^{+} \ra π^{+}π^{+}π^{-}$ ($D_{s}^{+} \ra π^{0}π^{0}π^{+}$) respectively.

description: We employ molecular-dynamics (MD) simulations to study grain boundary (GB) premelting in ices confined in two-dimensional hydrophobic nano-channels. Premelting transition is observed in a symmetric tilt GB in monolayer ices an involves the formation of a premelting band of liquid phase water with a width that grows logarithmically as the melting temperature is approached from below, consistent with the existing theory of GB premelting. Based on current MD observations, one may expect GB premelting exists over a wide range of low dimensional phases of confined ice and shows important consequences for crystal growth of low dimensional ices.

We contruct interpolating supergravity solutions that naturally represent the flow from the N=4 super Yang Mills UV theory to these non-supersymmetric IR fixed points. We also study the linearization around the N=4 superconformal point of N=1 supersymmetric, marginal deformations. We show that they give rise to N=1 superconformal fixed points, as expected from field-theoretical arguments.

description: Digital-to-analog converter (DAC) and analog-to-digital converter (ADC) as an important part of the superconducting quantum computer are used to control and readout the qubit states. The complexity of instrument manipulation increases rapidly as the number of qubits grows. Low-speed data transmission, imperfections of realistic instruments and coherent control of qubits are gradually highlighted which have become the bottlenecks in scaling up the number of qubits. To deal with the challenges, we present a solution in this study. Based on client-server (C/S) model, we develop two servers called Readout Server and Control Server for managing self-innovation digitizer, arbitrary waveform generator (AWG) and ultra-precision DC source which enable to implement physical experiments rapidly. Both Control Server and Readout Server consist three parts: resource manager, waveform engine and communication interface. The resource manager maps the resources of separate instruments to a unified virtual instrument and automatically aligns the timing of waveform channels. The waveform engine generates and processes the waveform for AWGs or captures and analyzes the data from digitizers. The communication interface is responsible for sending and receiving data in an efficient manner. We design a simple data link protocol for digitizers and a multi-threaded communication mechanism for AWGs. By using different network optimization strategies, both data transmission speed of digitizers and AWGs reach hundreds of Mbps through a single Gigabit-NIC.

description: A rarity among supernova, SN 1993J in M81 can be studied with high spatial resolution. Its radio power and distance permit VLBI observations to monitor the expansion of its angular structure. This radio structure was previously revealed to be shell-like and to be undergoing a self-similar expansion at a constant rate. From VLBI observations at the wavelengths of 3.6 and 6 cm in the period 6 to 42 months after explosion, we have discovered that the expansion is decelerating. Our measurement of this deceleration yields estimates of the density profiles of the supernova ejecta and circumstellar material in standard supernova explosion models.

Queremos, de esta manera, contribuir al analisis de las diferentes tensiones socioeconómicas, políticas y (trans)culturales que se originan en el marco de variadas luchas por condiciones de vida (más) digna. Partimos de la idea de que estas tensiones devienen de hechos multiformes acaecidos en la longue durée y que conviven con prácticas, materialidades y espacialidades que resisten, subvierten y sobrellevan situaciones o hechos ilegales, injustos, desiguales o antidemocráticos. A partir de casos concretos en diversos lugares de América Latina ofrecemos a nuestros lectores una mirada amplia al respecto, mediante diversos enfoques que los y las autoras emplean para discutir la dimensión de los conflictos vividos desde estudios históricos, arqueológicos, etnográficos, lingüísticos y culturales.

description: In this paper, we introduce the hierarchical B-spline complex of discrete differential forms for arbitrary spatial dimension. This complex may be applied to the adaptive isogeometric solution of problems arising in fluid mechanics. We derive a sufficient and necessary condition guaranteeing exactness of the hierarchical B-spline complex for arbitrary spatial dimension, and we derive a set of local, easy-to-compute, and sufficient exactness conditions for the two-dimensional setting. We examine the stability properties of the hierarchical B-spline complex, and we find that it yields stable approximations of both the Maxwell eigenproblem and Stokes problem provided that the local exactness conditions are satisfied. We conclude by providing numerical results showing the promise of the hierarchical B-spline complex in an adaptive isogeometric solution framework.

description: The Sachdev-Ye-Kitaev (SYK) model describes a strongly correlated metal with all-to-all random interactions (average strength $J$) between $N$ fermions (complex Dirac fermions or real Majorana fermions). In the large-$N$ limit a conformal symmetry emerges that renders the model exactly soluble. Here we study how the non-Fermi liquid behavior of the closed system in equilibrium manifests itself in an open system out of equilibrium. We calculate the current-voltage characteristic of a quantum dot, described by the complex-valued SYK model, coupled to a voltage source via a single-channel metallic lead (coupling strength $Γ$). A one-parameter scaling law appears in the large-$N$ conformal regime, where the differential conductance $G=dI/dV$ depends on the applied voltage only through the dimensionless combination $ξ=eVJ/Γ^2$. Low and high voltages are related by the duality $G(ξ)=G(π/ξ)$. This provides for an unambiguous signature of the conformal symmetry in tunneling spectroscopy.

description: Desde as tragédias das chuvas de Petrópolis em 1981 com 25 mortos e de Teresópolis, em 1981 com 30 mortos, os Vigilantes da chuva estudam quais as melhores formas de alertar as populações quanto aos riscos de deslizamentos e enchentes. No primeiro trabalho apresentado em 1984 no Primeiro Congresso Brasileiro de Defesa do Meio Ambiente no Clube da Engenharia no Rio de Janeiro, chegamos a valores de precipitação que causam o início de pequenos deslizamentos: 130mm em 24hs. Para as enchentes observamos valores de precipitação acima de 90 mm em 2 horas ou 45mm/h. Sabendo destes índices críticos, restava à população das áreas de risco ainda a aprender a saber medir os índices de precipitação. Foi aí que desenvolveu-se o pluviômetro artesanal, que apresentava vários níveis de perigo: Nível de chuva tranquilo até 30 mm, nível de Atenção -índices entre 30 e 60mm, nível de alerta de 60 a 100mm e índice de abandono acima de 100 mm. Neste nível de abandono os moradores saem das suas áreas de risco para áreas seguras livres de risco de deslizamentos.Em fevereiro de 1988 a Prefeitura de Petrópolis ignorou os dados de riscos apurados pelos Vigilantes da chuva na noite de 5 de fevereiro. O que aconteceu nesta noite foi catastrófico: 500 deslizamentos, 173 mortes, 1000 feridos e 4000 desabrigados.Já em 1990 e 1991, com o modelo de monitoramento das chuvas e do solo idealizado pelos vigilantes da chuva e implantado pela Defesa Civil Municipal de Petrópolis tivemos chuvas ainda maiores do que as de 1988: 176 mm e 156 mm respectivamente, contra 145 mm em 1988. Tivemos mais uma vez, mais de 500 deslizamentos, mas agora com 2 vítimas fatais, que não queriam sair de suas casas. O voluntariado da Defesa Civil e os vigilantes da chuva tiveram um papel fundamental nesta vitória contra mortes desnecessárias nos deslizamentos.

description: The betatron tune, which is defined as the number of transverse oscillations in one turn of a ring accelerator, is one of the most important parameters. An undesired betatron tune increases the amplitude of the transverse oscillation so that many particles are lost from the ring sooner than designed. Since a betatron tune is controlled by the magnetic fields in the ring, the ripple of the magnet current directly displaces the betatron tune from its designated value. We have developed a system that corrects the betatron tune displacement using the measured magnet current at the J-PARC (Japan Proton Accelerator Research Complex) Main Ring. We adopted Field Programmable Gated Arrays (FPGA) to convert from the measured magnet current to the betatron tune in real time. Using the system, we have decreased the fluctuation of the betatron tune from 5.2e-4 to 3.3e-4 at the frequencies less than 250 Hz.

name: Vilmart, Gilles
Publisher: name: Écublens, MATHICSE

description: A new explicit stabilized scheme of weak order one for stiff and ergodic stochastic differential equations (SDEs) is introduced. In the absence of noise, the new method coincides with the classical deterministic stabilized scheme (or Chebyshev method) for diffusion dominated advection-diffusion problems and it inherits its optimal stability domain size that grow quadratically with the number of internal stages of the method. For mean-square stable stiff stochastic problems, the scheme has an optimal extended mean-square stability domain that grows at the same quadratic rate as the deterministic stability domain size in contrast to known existing methods for stiff SDEs [A. Abdulle and T. Li. Commun. Math. Sci., 6(4), 2008, A. Abdulle, G. Vilmart, and K. C. Zygalakis, SIAM J. Sci. Comput., 35(4), 2013]. Combined with postprocessing techniques, the new methods achieve a convergence rate of order two for sampling the invariant measure of a class of ergodic SDEs, achieving a stabilized version of the non-Markovian scheme introduced in [B. Leimkuhler, C. Matthews, and M. V. Tretyakov, Proc. R. Soc. A, 470, 2014].

description: Large N gluodynamics was shown to have a set of metastable vacua with the gluonic domain walls interpolating between them. The walls may separate the genuine vacuum from an excited one, or two excited vacua which are unstable at finite N (here N is the number of colors). One may attempt to stabilize them by switching on the axion field. We study how the light quarks and the axion affect the structure of the domain walls. In pure gluodynamics (with the axion field) the axion walls acquire a very hard gluonic core. Thus, we deal with a wall "sandwich" which is stable at finite N. In the case of the minimal axion, the wall "sandwich" is in fact a "2-pi" wall, i.e., the corresponding field configuration interpolates between identical hadronic vacua. The same properties hold in QCD with three light quarks and very large number of colors. However, in the realistic case of three-color QCD the phase corresponding to the axion field profile in the axion wall is screened by a dynamical phase associated with the eta-prime, so that the gluon component of the wall is not excited. We propose a toy Lagrangian which models these properties and allows one to get exact solutions for the domain walls.

description: Quantum systems interacting with an unknown environment are notoriously difficult to model, especially in presence of non-Markovian and non-perturbative effects. Here we introduce a neural network based approach, which has the mathematical simplicity of the Gorini-Kossakowski-Sudarshan-Lindblad master equation, but is able to model non-Markovian effects in different regimes. This is achieved by using recurrent neural networks for defining Lindblad operators that can keep track of memory effects. Building upon this framework, we also introduce a neural network architecture that is able to reproduce the entire quantum evolution, given an initial state. As an application we study how to train these models for quantum process tomography, showing that recurrent neural networks are accurate over different times and regimes.

We compare our results with full Monte Carlo simulation using HERWIG. The importance of the hadronic component of the photon is also studied. We examine the possibility to distinguish among different parametrizations of the photon parton densities using charm production data, and the possibilty to extract information about the small-$x$ behaviour of the gluon density of the proton. We also give a prediction for the transverse momentum and pseudorapidity distributions for bottom production at HERA.

description: By explicit construction of the ADHM data, we prove the existence of a charge seven instanton with icosahedral symmetry. By computing the holonomy of this instanton we obtain a Skyrme field which approximates the minimal energy charge seven Skyrmion. We also present a one parameter family of tetrahedrally symmetric instantons whose holonomy gives a family of Skyrme fields which models a Skyrmion scattering process, where seven well-separated Skyrmions collide to form the icosahedrally symmetric Skyrmion.

description: We study the dilaton/axion configuration near D-instantons in type IIB superstring theory. In the field theory limit, the metric near the instantons becomes flat in the string frame as well as in the Einstein frame. In the large N limit, the string coupling constant becomes zero except near the origin. The supersymmetry of this configuration is analyzed. An implication of this result to the IIB Matrix Model is discussed.
description: Major revision; supersymmetry in Euclidean space re-examined. New conclusions: (1) the supersymmetry is not enhanced in the field theory limit. (2) the theory becomes free type IIB string theory in the large N limit, but the limit is not uniform. 9 pages, LaTeX

description: In this paper we propose a new, purely algebraic, Petrov-Galerkin reduced basis (RB) method to solve the parametrized Stokes equations, where parameters serve to identify the (variable) domain geometry. Our method is obtained as an algebraic least squares reduced basis (aLS-RB) method, and improves the existing RB methods for Stokes equations in several directions. First of all, it does not require to enrich the velocity space, as often done when dealing with a velocitypressure formulation, relying on a Petrov-Galerkin RB method rather than on a Galerkin RB (G-RB) method. Then, it exploits a suitable approximation of the matrix-norm in the definition of the (global) supremizing operator. The proposed method also provides a fully automated procedure to assemble and solve the RB problem, able to treat any kind of parametrization, and we rigorously prove the stability of the resulting aLS-RB problem (in the sense of a suitable inf-sup condition). Next, we introduce a coarse aLSRB (caLSRB) method, which is obtained by employing an approximated RB test space, and further improves the efficiency of the aLSRB method both offline and online. We provide numerical comparisons between the proposed methods and the current state-of-art G-RB methods. The new approach results in a more convenient option both during the offline and the online stage of computation, as shown by the numerical results.

description: THz Time-Resolved Photoconductivity is used to probe carrier dynamics in the dilute III-V nitride GaP0.49As0.47N0.036. In these measurements a femtosecond optical pump-pulse excites electron-hole pairs, and a delayed THz pulse measures the change in conductivity. We find the photoconductivity is dominated by localized carriers. The decay of photoconductivity after excitation is consistent with bimolecular electron-hole recombination with recombination constant r = 3.2E-8 +/-0.8E-8 cm3/s. We discuss the implications for applications in solar energy.

description: We derive semiclassical neutrino-electron transport equations in the collisionless (Vlasov) limit from the coupled Dirac equations, incorporating the charged and neutral weak current-current as well as electromagnetic interactions. A corresponding linear response theory is derived. In particular, we calculate the response functions for a variety of beam-plasma geometries, which are of interest in a supernova scenario. We apply this to the study of plasmons and to a new class of collective {\it pharon} resonance modes, which are characterized by $ω< q$. We find that the growth rates of the unstable modes correspond to a strongly temperature ($\propto T_ν^2T_e^3$) and linearly momentum dependent e-folding length of about $10^{10}$ km under typical conditions for Type II supernovae. This appears to rule out such long-wavelength collective modes as an efficient means of depositing neutrino energy into the plasma sphere.

description: We propose a novel strategy to test lepton flavor universality (LFU) in top decays, applicable to top pair production at colliders. Our proposal exploits information in kinematic distributions and mostly hinges on data-driven techniques, thus having very little dependence on our theoretical understanding of top pair production. Based on simplified models accommodating recent hints of LFU violation in charged current B meson decays, we show that existing LHC measurements already provide non-trivial information on the flavor structure and the mass scale of such new physics (NP). We also project that the measurements of LFU in top decays at the high-luminosity LHC could reach a precision at the percent level or below, improving the sensitivity to LFU violating NP in the top sector by more than an order of magnitude compared to existing approaches.

MATHICSE Technical Report : Numerical approximation of parametrized problems in cardiac electrophysiology by a local reduced basis method
Creators: name: Pagani, Stefano

description: The efficient solution of coupled PDEs/ODEs problems arising in cardiac electrophysiology is of key importance whenever interested to study the electrical behavior of the tissue for several instances of relevant physical and/or geometrical parameters. This poses significant challenges to reduced order modeling (ROM) techniques – such as the reduced basis method – traditionally employed when dealing with the repeated solution of parameter dependent differential equations. Indeed, the nonlinear nature of the problem, the presence of moving fronts in the solution, and the high sensitivity of this latter to parameter variations, make the application of standard ROM techniques very problematic. In this paper we propose a local ROM built through a k-means clustering in the state space of the snapshots for both the solution and the nonlinear term. Several comparisons among alternative local ROMs on a benchmark test case show the effectivity of the proposed approach. Finally, the application to a parametrized problem set on an idealized leftventricle geometry shows the capability of the proposed ROM to face complex problems.

Through Electromagnetic Simulation, performed with CST Studio Suite, new panels design are tested and their crosstalk property are studied. The behavior of different type of panel is shown, in particular a panel with the decoupling strip connected through their characteristic impedance to the ground plane is simulated.
Revisiting the Modified Eddington Limit for Massive Stars

description: We have determined the location of the line-opacity modified Eddington limit for stars in the LMC using the most recent atmosphere models combined with a precise mapping to the HR Diagram through up-to-date stellar evolution calculations. While we find, in agreement with previous studies, that the shape of the modified Eddington limit qualitatively corresponds to the Humphreys-Davidson (HD) limit defined by the most luminous supergiants, the modified limit is actually a full magnitude higher than the upper luminosity limit observed for LMC stars. The observed limit is consistent with atmosphere models in which the maximum value of the ratio of the radiation force outwards to the gravitational force inwards, Y_max, is 0.9, i.e., the photospheres of stars at the observed luminosity limit are bound. As massive stars evolve, they move to higher, and therefore less stable values of Y_max, so mass loss, either sporadic or continuous, may halt their natural redward evolution as they approach the Y_max = 0.9 limit. We assess the metallicity dependence of this limit. If the limit does determine the most luminous stars, and the value of Y_max corresponding to the luminosity limit in the LMC is universal, then the brightest supergiants the SMC should be only marginally brighter (0.3 mag) than those of the LMC, in agreement with observations. Moreover, the brightest supergiants in M31 should be 0.75~mag fainter than those in the LMC.
