description: We apply to lattice QCD a bosonization method previously developed in which dynamical bosons are generated by time-dependent Bogoliubov transformations. The transformed action can be studied by an expansion in the inverse of the nilpotency index, which is the number of fermionic states in the structure function of composite bosons. When this number diverges the model is solved by the saddle point method which has a variational interpretation. We give a stationary covariant solution for a background matter field whose fluctuations describe mesons. In the saddle point approximations live fermionic quasiparticles with quark quantum numbers which are confined, in the sense that they propagate only in pointlike color singlets. Conditions for chiral symmetry breaking are determined, to be studied numerically, and a derivation of mesons-nucleons action is outlined.

description: Context: Discrete symmetries have found numerous applications in photonics and quantum mechanics, but remain little studied in fluid mechanics, particularly in astrophysics. Aims: We aim to show how PT and anti-PT symmetries determine the behaviour of linear perturbations in a wide class of astrophysical problems. They set the location of Exceptional Points in the parameter space and the associated transitions to instability, and are associated to the conservation of quadratic quantities that can be determined explicitly. Methods: We study several classical local problems: the gravitational instability of isothermal spheres and thin discs, the Schwarzschild instability, the Rayleigh-Bénard instability and acoustic waves in dust-gas mixtures. We calculate the locations and the order of the Exceptional Points with a method of resultant, as well as the conserved quantities in the different regions of the parameter space using Krein theory. Results: All problems studied here exhibit discrete symmetries, even though Hermiticity is broken by different physical processes (self-gravity, buoyancy, diffusion, drag). This analysis provides genuine explanations for certain instabilities, and for the existence of regions in the parameter space where waves do not propagate. Those correspond to breaking of PT and anti-PT symmetries respectively. Not all instabilities are associated to symmetry breaking (e.g. the Rayleigh-Benard instability).

description: We investigate the asymptotic behavior of posterior distributions of regression coefficients in high-dimensional linear models as the number of dimensions grows with the number of observations. We show that the posterior distribution concentrates in neighborhoods of the true parameter under simple sufficient conditions. These conditions hold under popular shrinkage priors given some sparsity assumptions.

description: The Wannier-Stark localization dynamically alters the entanglement behavior of non-Hermitian free fermions. Utilizing the single-particle correlation matrix technique, we analyze the effective Hamiltonian of these fermions with a Wannier-Stark ladder. Under open boundary conditions, we observe the steady state half-chain entanglement entropy and identify two distinct area law regions and an algebraic scaling region. Finite-size scaling analysis reveals critical scaling behavior of the half-chain entanglement entropy. Notably, the system demonstrates unique entanglement characteristics under periodic boundary conditions, which diverge from the (1+1)d conformal field theory predictions for Anderson localization. Our findings highlight novel entanglement phases emerging from the interplay between the non-Hermitian skin effect and disorder-free localization.

Three-phase DC-DC resonant converters for high-power battery charging applications
Creators: name: Arshadi, Sayed Abbas
Publisher: name: University of British Columbia
Year: 2022

description: Resonant power converters have gained popularity in many application, especially where there are strict requirements on efficiency, power density, and Electromagnetic Compability (EMC). Among different types of resonant converters, LLC and CLLC resonant converters have attracted more attention for uni-directional and bi-directional applications, respectively. This is due to the unique features of these types of converters, such as soft switching. Half-bridge and full-bridge resonant structures have are suitable for low to medium power levels, and three-phase structures are considered for higher power levels. Three-phase resonant converters provide high efficiency, low current ripple, good thermal distribution, and small filter and heat sink size (high power density), that makes them an attractive option for high power battery charger applications. Although there has been substantial research and development on single-phase LLC and CLLC resonant converters for low to medium power levels, the literature investigating three-phase structures has been very limited. Issues to be investigated for three phase resonant converters are: 1) passive components tolerances, which leads to unbalanced behavior of the converter, 2) development of a balancing technique to mitigate the unbalanced behavior of the converter, 3) the natural limited gain range of resonant converter structure, 4) poor light load efficiency of the three-phase resonant converter and possible phase shedding strategies to improve it, and also to increase the reliability of the system. In this work, methods to use three-phase LLC and CLLC resonant converters more efficiently are investigated. This includes: 1) investigation of imbalances in three-phase LLC converters and proposing a novel strategy referred to as Trigonometric Current Balancing (TCB) technique to mitigate the unbalanced behavior of the converter under sever unbalanced situation, 2) investigating phase-shedding techniques and strategies to improve the operation of the converter at light load conditions and extend the gain range of the converter, and 3) investigating the behavior of the three-phase CLLC resonant converter for bi-directional power applications.

description: Based on the geometrical approach to tunnelling by P.D. Hislop and I.M. Sigal [Memoir. AMS 78, No. 399 (1989)], we introduce the concept of a leading tunnelling trajectory. It is then proven that leading tunnelling trajectories for single-active-electron models of molecular tunnelling ionization (i.e., theories where a molecular potential is modelled by a single-electron multi-centre potential) are linear in the case of short range interactions and "almost" linear in the case of long range interactions. The results are presented on both the formal and physically intuitive levels. Physical implications of the obtained results are discussed.

Dynamics of star clusters with tangentially anisotropic velocity distribution

description: Recent high-precision observations with HST and Gaia enabled new investigations of the internal kinematics of star clusters (SCs) and the dependence of kinematic properties on the stellar mass. These studies raised new questions about the dynamical evolution of self-gravitating stellar systems. We aim to develop a more complete theoretical understanding of how various kinematical properties of stars affect the global dynamical development of their host SCs. We perform N-body simulations of SCs with isotropic, radially anisotropic and tangentially anisotropic initial velocity distributions. We also study the effect of an external Galactic tidal field. We find three main results. First, compared to the conventional, isotropic case, the relaxation processes are accelerated in the tangentially anisotropic models and, in agreement with our previous investigations, slower in the radially anisotropic ones. This leads to, e.g., more rapid mass segregation in the central regions of the tangential models or their earlier core collapse. Second, although all SCs become isotropic in the inner regions after several relaxation times, we observe differences in the anisotropy profile evolution in the outer cluster regions - all tidally filling models gain tangential anisotropy there while the underfilling models become radially anisotropic. Third, we observe different rates of evolution towards energy equipartition (EEP). While all SCs evolve towards EEP in their inner regions (regardless of the filling factor), the outer regions of the tangentially anisotropic and isotropic models are evolving to an "inverted" EEP (i.e., the high-mass stars having higher velocity dispersion than the low-mass ones). The extent (both spatial and temporal) of this inversion can be attributed to the initial velocity anisotropy - it grows with increasing tangential anisotropy and decreases as the radial anisotropy rises.

description: With inspiration from Random Forests (RF) in the context of classification, a new clustering ensemble method---Cluster Forests (CF) is proposed. Geometrically, CF randomly probes a high-dimensional data cloud to obtain "good local clusterings" and then aggregates via spectral clustering to obtain cluster assignments for the whole dataset. The search for good local clusterings is guided by a cluster quality measure kappa. CF progressively improves each local clustering in a fashion that resembles the tree growth in RF. Empirical studies on several real-world datasets under two different performance metrics show that CF compares favorably to its competitors. Theoretical analysis reveals that the kappa measure makes it possible to grow the local clustering in a desirable way---it is "noise-resistant". A closed-form expression is obtained for the mis-clustering rate of spectral clustering under a perturbation model, which yields new insights into some aspects of spectral clustering.

description: State mapping between atoms and photons, and photon-photon interactions play an important role in scalable quantum information processing. We consider the interaction of a two-level atom with a quantized \textit{propagating} pulse in free space and study the probability $P_e(t)$ of finding the atom in the excited state at any time $t$. This probability is expected to depend on (i) the quantum state of the pulse field and (ii) the overlap between the pulse and the dipole pattern of the atomic spontaneous emission. We show that the second effect is captured by a single parameter $Λ\in[0,8π/3]$, obtained by weighting the dipole pattern with the numerical aperture. Then $P_e(t)$ can be obtained by solving time-dependent Heisenberg-Langevin equations. We provide detailed solutions for both single photon Fock state and coherent states and for various temporal shapes of the pulses.

description: A general iterative method proposed some years ago for the description of relativistic collapse, is presented here in comoving coordinates. For doing that we redefine the basic concepts required for the implementation of the method for comoving coordinates. In particular the definition of the post-quasistatic approximation in comoving coordinates is given. We write the field equations, the boundary conditions and a set of ordinary differential equations (the surface equations) which play a fundamental role in the algorithm. As an illustration of the method, we show how to build up a model inspired in the well known Schwarzschild interior solution. Both, the adiabatic and non adiabatic, cases are considered.

Transmission properties of the process governed by the Schrödinger equation with the white noise potential can be expressed through the Lyapunov exponent $γ$ which we determine explicitly as a function of the noise intensity σand the frequency ω. We find uniform two-parameter asymptotic expressions for $γ$ which allow us to evaluate $γ$ for different relations between σand ω. The value of the Lyapunov exponent is also obtained in the case of a short-range correlated noise, which is shown to be less than its white noise counterpart.

Acceleration from a clustering environment

Year: 2024
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We study the effects of correlations in a random environment on a random walker. The dependence of its asymptotic speed on the correlations is a nonperturbative effect as it is not captured by a homogeneous version of the same environment. For a slowly cooling environment, the buildup of correlations modifies the walker's speed and, by so, realizes acceleration. We remark on the possible relevance in the discussion of cosmic acceleration as traditionally started from the Friedmann equations, which, from a statistical mechanical point of view, would amount to a mean-field approximation. Our environment is much simpler though, with transition rates sampled from the one-dimensional Ising model and allowing exact results and detailed velocity characteristics.

Epigenomic programming in early fetal brain development

Publisher: name: University of British Columbia

description: A comprehensive understanding of gene regulatory networks in the developing human brain provides a foundation for interpreting pathogenic deregulation. Here we analyzed the complete epigenomes and transcriptomes of dissected brain regions and primary neural progenitor cells (NPCs) derived from cortex and ganglionic eminence (GE) of four human fetuses including a pair of monozygotic twins. Epigenetic regulatory states were compared between NPCs derived from cortex and GE, across developmental stages, and between monozygotic twins. Comparisons across developmental stages reveal an increase in active epigenetic states, transcription factor activities and gene transcription with increasing developmental stage. NPCs derived from different brain regions retained brain region and gestational week specific regulatory states. We also found evidence of divergent epigenetic signatures between monozygotic twins before midgestation.

description: We present Gemini Multi-Object Spectrograph (GMOS) spectroscopic observations of 95 galaxies from the Arp & Madore (1987) catalogue of peculiar galaxies. These galaxies have been selected because they appear to be in pairs and small groups. These observations have allowed us to confirm that 60 galaxies are indeed interacting systems. For the confirmed interacting sample, we have built a matched control sample of isolated galaxies. We present an analysis of the stellar populations and nuclear activity in the interacting galaxies and compare them with the isolated galaxies. We find a median light (mass) fraction of 55% (10%) in the interacting galaxies coming from stellar populations younger than 2 Gyr and 28% (3%) in the case of the isolated galaxies. More than half of the interacting galaxies are dominated by this young stellar population, while the isolated ones have most of their light coming from older stellar populations. We used a combination of diagnostic diagrams (BPTs and WHAN) to classify the main ionization mechanisms of the gas. The interacting galaxies in our sample consistently show a higher fraction of active galactic nuclei (AGN) relative to the control sample, which ranges between 1.6 and 4 depending on the combination of diagnostic diagrams employed to classify the galaxies and the number of galaxies considered. Our study provides further observational evidence that interactions drive star formation and nuclear activity in galaxies and can have a significant impact on galaxy evolution.

description: The origin of galactic and extra-galactic magnetic fields is an unsolved problem in modern cosmology. A possible scenario comes from the idea of these fields emerged from a small field, a seed, which was produced in the early universe (phase transitions, inflation, ...) and it evolves in time. Cosmological perturbation theory offers a natural way to study the evolution of primordial magnetic fields. The dynamics for this field in the cosmological context is described by a cosmic dynamo like equation, through the dynamo term. In this paper we get the perturbed Maxwell's equations and compute the energy momentum tensor to second order in perturbation theory in terms of gauge invariant quantities. Two possible scenarios are discussed, first we consider a FLRW background without magnetic field and we study the perturbation theory introducing the magnetic field as a perturbation. The second scenario, we consider a magnetized FLRW and build up the perturbation theory from this background. We compare the cosmological dynamo like equation in both scenarios.

description: This is the online appendix of the paper Luca Gazzola, Maayan Goldstein, Leonardo Mariani, Marco Mobilio, Itai Segall, Alessandro Tundo and Luca Ussi. "ExVivoMicroTest: Ex-Vivo Testing of Microservices." Journal of Software: Evolution and Process (Special Issue: Automation of Software Test and Test Code Quality). The abstract of the paper follows: Microservice-based applications consist of multiple services that can evolve independently. When a service must be updated, it is first tested with in-house regression test suites. However, the test suites that are executed are usually designed without the exact knowledge about how the services will be accessed and used in the field, therefore they may easily miss relevant test scenarios, failing to prevent the deployment of faulty services.
 To address this problem, we introduce ExVivoMicroTest, an approach that analyzes the execution of deployed services at run-time in the field, in order to generate test cases for future versions of the same services. ExVivoMicroTest implements lightweight monitoring and tracing capabilities, to inexpensively record executions that can be later turned into regression test cases that capture how services are used in the field. To prevent accumulating an excessive number of test cases, ExVivoMicroTest uses a test coverage model that can discriminate the recorded executions between the ones that are worth to be turned into test cases and the ones that should be discarded. The resulting test cases use a mocked environment that fully isolates the service under test from the rest of the system to faithfully reply interactions.
 We assessed ExVivoMicroTest with the PiggyMetrics and Train Ticket open source microservice applications and studied how different configurations of the monitoring and tracing logic impact on the capability to generate test cases.

The eventful life of GS-z14-0, the most distant galaxy at redshift $z=14.32$

description: We developed a model for the star formation history (SFH) of super-early galaxies and applied it to GS-z14-0, the most distant galaxy known, located at $z=14.32$ (294 million years after the Big Bang). The SFH, starting at $z=26.7$, is complex. Initially ($z>18$), the galaxy experiences feedback-regulated phases that are bursty, relatively faint (reaching $M_{\rm UV}=-18.4$), and unattenuated. When dust shielding allows for a smooth star formation rate (SFR), the galaxy quickly becomes heavily obscured. During this obscured phase, which lasts for approximately 20% of the total star-forming time, 70% of the observed stars are formed. Super-early galaxies in this phase should be detectable by ALMA. Twenty-six million years before observation, as the galaxy becomes super-Eddington, a powerful radiation-driven outflow clears most of the dust and significantly reduces the SFR by a factor of seven, from $100 \to 15\ M_\odot \rm yr^{-1}$. The galaxy transitions into a "blue monster" dominating the bright end of the UV luminosity function. When the outflow ceases due to decreased dust opacity, the galaxy relaxes into a post-starburst phase, in which it is currently observed. Our model accurately reproduces all the observed and inferred properties of the galaxy. The analysis of this extreme system opens exciting opportunities for studying the beginnings of the luminous Universe.

description: We consider the bipartite version of the degree/diameter problem, namely, given natural numbers Δ \geq 2 and D \geq 2, find the maximum number Nb(Δ,D) of vertices in a bipartite graph of maximum degree Δ and diameter D. In this context, the Moore bipartite bound Mb(Δ,D) represents an upper bound for Nb(Δ,D). Bipartite graphs of maximum degree Δ, diameter D and order Mb(Δ,D), called Moore bipartite graphs, have turned out to be very rare. Therefore, it is very interesting to investigate bipartite graphs of maximum degree Δ \geq 2, diameter D \geq 2 and order Mb(Δ,D) - εwith small ε> 0, that is, bipartite (Δ,D,-ε)-graphs. The parameter εis called the defect. This paper considers bipartite graphs of defect at most 4, and presents all the known such graphs. Bipartite graphs of defect 2 have been studied in the past; if Δ \geq 3 and D \geq 3, they may only exist for D = 3. However, when ε> 2 bipartite (Δ,D,-ε)-graphs represent a wide unexplored area. The main results of the paper include several necessary conditions for the existence of bipartite $(Δ,d,-4)$-graphs; the complete catalogue of bipartite (3,D,-ε)-graphs with D \geq 2 and 0 \leq ε\leq 4; the complete catalogue of bipartite (Δ,D,-ε)-graphs with Δ \geq 2, 5 \leq D \leq 187 (D /= 6) and 0 \leq ε\leq 4; and a non-existence proof of all bipartite (Δ,D,-4)-graphs with Δ \geq 3 and odd D \geq 7. Finally, we conjecture that there are no bipartite graphs of defect 4 for Δ \geq 3 and D \geq 5, and comment on some implications of our results for upper bounds of Nb(Δ,D).

Effect of synergistic cold alkaline swelling and mechanical disintegration on the formation of biodegradable and translucent cellulose film
Creators: name: Tian, Sibo
Publisher: name: University of British Columbia

description: The objective of this work was to develop a path to create a plastic film alternative in packaging applications using cellulose materials. It was expected that a small amount of chemical and energy are needed during the process to align with the principles of eco-friendly development and sustainable development. It was also anticipated that the product of this work should have favorable optical properties and good mechanical performance comparable to ordinary plastic film products. In this study, without going through dissolution or nanofibrillation, Northern Bleached Softwood Kraft (NBSK) cellulose pulp is treated with a 10% NaOH solution at a subzero temperature (-10 °C) and mechanical disintegration using a domestic blender to create a substitute that resembles plastic films. The kraft pulp can be converted into a stable fibrous slurry that can then be processed into a translucent and hazy film using vacuum filtration. The prepared cellulose film demonstrated high transmittance (89% at 650 nm with integrated sphere), excellent biodegradability (completely degrade in 19 days when buried in soil), high mechanical strength (99.7 MPa tensile strength in the dry state and 17.2 MPa after being immersed in water for 30 days), and high thermal stability (Tmax of 350 °C). In sum, in this study a translucent, hazy, and strong cellulose film was developed through a simple chemical-saving and energy-saving fabrication method which involves treatment in 10% NaOH solution at -10 °C, blending and vacuum filtration, showing great promise as plastic alternative for packaging applications.

description: Linear complementary dual (LCD) codes can be used to against side-channel attacks and fault noninvasive attacks. Let $d_{a}(n,6)$ and $d_{l}(n,6)$ be the minimum weights of all binary optimal linear codes and LCD codes with length $n$ and dimension 6, respectively.In this article, we aim to obtain the values of $d_{l}(n,6)$ for $n\geq 51$ by investigating the nonexistence and constructions of LCD codes with given parameters. Suppose that $s \ge 0$ and $0\leq t\leq 62$ are two integers and $n=63s+t$. Using the theories of defining vectors, generalized anti-codes, reduced codes and nested codes, we exactly determine $d_{l}(n,6)$ for $t \notin\{21,22,25,26,33,34,37,38,45,46\}$, while we show that $d_{l}(n,6)\in$$\{d_{a}(n,6)$ $-1,d_{a}(n,6)\}$ for $t\in\{21,22,26,34,37,38,46\}$ and $ d_{l}(n,6)\in$$ \{d_{a}(n,6)-2,$ $d_{a}(n,6)-1\}$ for$t\in{25,33,45\}$.

description: Electron cooling is a well-established method to improve the phase space quality of ion beams in storage rings. In the common rest frame of the ion and the electron beam the ion is subjected to a drag force and it experiences a loss or a gain of energy which eventually reduces the energy spread of the ion beam. A calculation of this process is complicated as the electron velocity distribution is anisotropic and the cooling process takes place in a magnetic field which guides the electrons. In this paper the cooling force is calculated in a model of binary collisions (BC) between ions and magnetized electrons, in which the Coulomb interaction is treated up to second-order as a perturbation to the helical motion of the electrons. The calculations are done with the help of an improved BC theory which is uniformly valid for any strength of the magnetic field and where the second-order two-body forces are treated in the interaction in Fourier space without specifying the interaction potential. The cooling force is explicitly calculated for a regularized and screened potential which is both of finite range and less singular than the Coulomb interaction at the origin. Closed expressions are derived for monochromatic electron beams, which are folded with the velocity distributions of the electrons and ions. The resulting cooling force is evaluated for anisotropic Maxwell velocity distributions of the electrons and ions.

description: We consider the Klein--Gordon equation associated with the Laplace--Beltrami operator $Δ$ on real hyperbolic spaces of dimension $n\!\ge\!2$; as $Δ$ has a spectral gap, the wave equation is a particular case of our study. After a careful kernel analysis, we obtain dispersive and Strichartz estimates for a large family of admissible couples. As an application, we prove global well--posedness results for the corresponding semilinear equation with low regularity data.

description: A series of morphotropic phase boundary (MPB) compositions of (1–x)Na₁/₂Bi₁/₂TiO₃‐xBaTiO₃ (x = 0.05, 0.055, 0.06, 0.065, 0.07), with and without 0.5 mol% Zn‐doping was synthesized using the solid‐state route. The samples were characterized using X‐ray diffraction, dielectric analysis, and electromechanical measurements (piezoelectric d₃₃ coefficient, coupling factor kp, mechanical quality factor Qm, and internal bias field Ebias). The increase in the ferroelectric‐relaxor transition temperature upon Zn‐doping was accompanied by a shift of the MPB toward the Na₁/₂Bi₁/₂TiO₃‐rich side of the phase diagram. Higher tetragonal phase fraction and increased tetragonal distortion were noted for Zn‐doped (1 – x)Na₁/₂Bi₁/₂TiO₃‐xBaTiO₃. In addition, ferroelectric hardening and the presence of an internal bias field (Ebias) were observed for all doped compositions. The piezoelectric constant d₃₃ and the coupling coefficient kp decreased by up to ∼30%, while a 4‐ to 6‐fold increase in Qm was observed for the doped compositions. Apart from establishing a structure–property correlation, these results highlight the chemically induced shift of the phase diagram upon doping, which is a crucial factor in material selection for optimal performance and commercialization.
Morphological Study of Ice Crystal Growth

Publisher: name: California Institute of Technology

description: The morphologies and growth rates of ice crystals have been observed and documented using a novel experiment, with the goal of investigating the overarching principles of the molecular dynamics of ice crystal growth. The experimental set-up consists of two side-by-side temperature-regulated diffusion chambers. Thin ice needles, up to several millimeters in length and a few microns in diameter, are grown in the first chamber off of a metal wire through nucleation caused by the application of a high voltage. These electric needles are then transferred to the second chamber with a controllable internal water vapor supersaturation level, and subsequent growth of the ice crystals is observed. The crystal morphology is captured digitally via optical microscopy and is analyzed in the form of time-stamped images.

Varying the supersaturation and overall temperature affects the crystal morphology as well as growth rate and yields insights into the basic physical principles governing crystal growth. A theory that proposes to explain the resulting morphology of ice crystals due to variations in temperature and supersaturation conditions suggests that relative growth rates of the principal facets of a crystal depend on the current morphology of the crystal and on an instability. Computer simulations of this proposed theory called the Structure-Dependent Attachment Kinetics model are tested against real ice crystals to determine the accuracy of the proposed theory.
