Towards understanding the Pierce-Birkhoff conjecture via MV-algebras

Subjects: subject: Logic (math.LO)
subject: FOS: Mathematics

description: Our main issue was to understand the connection between Łukasiewicz logic with product and the Pierce-Birkhoff conjecture, and to express it in a mathematical way. To do this we define the class of \textit{f}MV-algebras, which are MV-algebras endowed with both an internal binary product and a scalar product with scalars from $[0,1]$. The proper quasi-variety generated by $[0,1]$, with both products interpreted as the real product, provides the desired framework: the normal form theorem of its corresponding logical system can be seen as a local version of the Pierce-Birkhoff conjecture.
Black hole quasinormal modes in a scalar-tensor theory with field derivative coupling to the Einstein tensor

Year: 2014

description: We investigate the quasinormal modes of a test massless, minimally coupled scalar field on a static and spherically symmetric black hole in the scalar-tensor theory with field derivative coupling to the Einstein tensor, which is a part of the Horndeski theory with the shift symmetry. In our solution, the spacetime is asymptotically AdS (anti-de Sitter), where the effective AdS curvature scale is determined solely by the derivative coupling constant. The metric approaches the AdS spacetime in the asymptotic infinity limit and precisely recovers the Schwarzschild-AdS solution in general relativity if the coupling constant is tuned to the inverse of the cosmological constant. We numerically find the lowest lying quasinormal frequency for the perturbation about a test massless, minimally coupled scalar field. The quasinormal frequency agrees with that of the Schwarzschild-AdS solution for the tuned case. For other parameters, in the large black hole limit, as the metric coincides with that of the Schwarzschild-AdS black hole, the quasinormal frequency almost agrees with that of the Schwarzschild-AdS black hole and is insensitive to the value of the cosmological constant. On the other hand, for a small back hole the real part of the quasinormal frequency decreases as the absolute value of the cosmological constant increases.

description: We calculate the proton and neutron spin contributions for nuclei using semi-empirical methods, as well as a novel hybrid \emph{ab initio}/semi-empirical method, for interpretation of experimental data. We demonstrate that core-polarisation corrections to \emph{ab initio} nuclear shell model calculations generally reduce discrepancies in proton and neutron spin expectation values from different calculations. We derive constraints on the spin-dependent P,T-violating interaction of a bound proton with nucleons, which for certain ranges of exchanged pseudoscalar boson masses improve on the most stringent laboratory limits by several orders of magnitude. We derive a limit on the CPT and Lorentz-invariance-violating parameter $|\tilde{b}_{\perp}^p| < 7.6 \times 10^{-33}$ GeV, which improves on the most stringent existing limit by a factor of 8, and demonstrate sensitivities to the parameters $\tilde{d}_{\perp}^p$ and $\tilde{g}_{ D\perp}^p$ at the level $\sim 10^{-29} - 10^{-28}$ GeV, which is a one order of magnitude improvement compared to the corresponding existing sensitivities. We extend previous analysis of nuclear anapole moment data for Cs to obtain new limits on several other CPT and Lorentz-invariance-violating parameters: $\left|b_0^p \right| < 7 \times 10^{-8}$ GeV, $\left|d_{00}^p \right| < 8 \times 10^{-8}$, $\left|b_0^n \right| < 3 \times 10^{-7}$ GeV and $\left|d_{00}^n \right| < 3 \times 10^{-7}$.

description: We discuss the physics of {\it restricted Weyl invariance}, a symmetry of dimensionless actions in four dimensional curved space time. When we study a scalar field nonminimally coupled to gravity with Weyl(conformal) weight of $-1$ (i.e. scalar field with the usual two-derivative kinetic term), we find that dimensionless terms are either fully Weyl invariant or are Weyl invariant if the conformal factor $Ω(x)$ obeys the condition $g^{μν}\nabla_μ\nabla_νΩ=0$. We refer to the latter as {\it restricted Weyl invariance}. We show that all the dimensionless geometric terms such as $R^2$, $R_{μν}R^{μν}$ and $R_{μνστ}R^{μνστ}$ are restricted Weyl invariant. Restricted Weyl transformations possesses nice mathematical properties such as the existence of a composition and an inverse in four dimensional space-time. We exemplify the distinction among rigid Weyl invariance, restricted Weyl invariance and the full Weyl invariance in dimensionless actions constructed out of scalar fields and vector fields with Weyl weight zero.

Quantum potential energy as concealed motion

description: It is known that the Schroedinger equation may be derived from a hydrodynamic model in which the Lagrangian position coordinates of a continuum of particles represent the quantum state. Using Routh\s method of ignorable coordinates it is shown that the quantum potential energy of particle interaction that represents quantum effects in this model may be regarded as the kinetic energy of additional concealed freedoms. The method brings an alternative perspective to Planck\s constant, which plays the role of a hidden variable, and to the canonical quantization procedure, since what is termed kinetic energy in quantum mechanics may be regarded literally as energy due to motion.

description: Let $X$ be an abstract not necessarily compact orientable CR manifold of dimension $2n-1$, $n\geqslant2$. Let $\Box^{(q)}_{b}$ be the Gaffney extension of Kohn Laplacian for $(0,q)$-forms. We show that the spectral function of $\Box^{(q)}_b$ admits a full asymptotic expansion on the non-degenerate part of the Levi form. As a corollary, we deduce that if $X$ is compact and the Levi form is non-degenerate of constant signature on $X$, then the spectrum of $\Box^{(q)}_b$ in $]0,\infty[$ consists of point eigenvalues of finite multiplicity. Moreover, we show that a certain microlocal conjugation of the associated Szegö kernel admits an asymptotic expansion under a local closed range condition. As applications, we establish the Szegö kernel asymptotic expansions on some weakly pseudoconvex CR manifolds and on CR manifolds with transversal CR $S^1$ actions. By using these asymptotics, we establish some local embedding theorems on CR manifolds and we give an analytic proof of a theorem of Lempert asserting that a compact strictly pseudoconvex CR manifold of dimension three with a transversal CR $S^1$ action can be CR embedded into $\mathbb{C}^N$, for some $N\in\mathbb N$.

Novel Ambiguities in the Seiberg-Witten Map and the Emergent Gravity

description: A homogeneous part of the Seiberg-Witten gauge equivalence relation for gauge fields can lead to solutions that involve matter fields in such a way that the gauge equivalence and the dimensional and index structures are preserved. In particular, we consider scalar fields coupled to U(1) gauge fields. The matter fields appear non-linearly in the map. As an application, we analyze the implication of this ambiguity to emergent gravity at the first order in noncommutative parameter and show that the new ambiguity restores the possibility of conformal coupling of real scalar density field that is coupled non-minimally to the emergent gravity induced by gauge fields -- a possibility that is strictly not allowed if we consider only the already known ambiguity in the Seiberg-Witten map.

description: We consider three dimensional Einstein gravity non-minimally coupled to a real scalar field with a self-interacting scalar potential and present the exact black hole formation in three dimensions. Firstly we obtain an exact time-dependent spherically symmetric solution describing the gravitational collapse to a scalar black hole at the infinite time, i.e. in the static limit. The solution can only be asymptotically AdS because of the No-Go theorem in three dimensions which is resulted from the existence of a smooth black hole horizon. Then we analyze their geometric properties and properties of the time evolution. We also get the exact time-dependent solution in the minimal coupling model after taking a conformal transformation.

description: We describe and characterize a device for alkali vapor pressure modulation on the 100ms timescale in a single-cell cold atom experiment. Its mechanism is based on optimized heat conduction between a current-modulated alkali dispenser and a heat sink at room temperature. We have studied both the short-term behavior during individual pulses and the long-term pressure evolution in the cell. The device combines fast trap loading and relatively long trap lifetime, enabling high repetition rates in a very simple setup. These features make it particularly suitable for portable atomic sensors.

description: In the oil and gas industry, “flow assurance” incorporates the efforts to prevent inadvertent disruptions to the hydrocarbon flow from the wells to processing facilities. It is a reference to the study of both organic and inorganic deposits that may hinder production. Such deposits are mainly formed by scale, hydrate, asphaltene, and wax. This dissertation enhances the modeling of flow-assurance issues within a single platform—UTWELL, a wellbore simulator developed at The University of Texas at Austin. Scales result from mineral precipitation due to changes in pressure and temperature along the water flow, inherent to any gas/oil production. This research focuses on how water evaporation and CO₂ affect scaling tendencies in an oil well. The results demonstrate that evaporation is only relevant for very a small amount of water in the system, characteristic of the early stages of production. Additionally, the model shows that gas lift can increase mineral precipitation depending on the CO₂ content from the injected gas. Hydrates are ice-like solids formed under high-pressure and low-temperature conditions that are commonly found in an oilfield. Hydrate formation can be inhibited either by dissolved ions (electrolytes) in the produced water or by deliberate injection of chemicals. This research develops a hydrate-check model to verify formation conditions along the flow. The integration with a geochemical package (PHREEQC) provides the tools to consider electrolyte inhibition, and a newly included equation of state (CPA) assesses the inhibition effect from added glycols (and alcohols). The model predicts that when gas-water ratio (GWR) exceeds 10⁵ scf/STB, water condensation reduces electrolyte inhibition significantly. On asphaltenes, this research also discusses two prediction methods: a consolidated model from Li and Firoozabadi (2010), using a simplified version of the cubic-plus-association equation of state (CPA EoS); and a newly proposed version of a solid model, based on the Peng-Robinson EoS. It is shown that, if provided with adequate onset data, the solid model can match results from the CPA model quite successfully, while requiring only half the computational time. However, the solid model cannot adjust to composition changes in the same manner as CPA. Therefore, its adoption seems more suitable for wellbore simulation than in the reservoir, where fluid mixing is widespread.
Hyperuniformity of critical absorbing states

description: The properties of the absorbing states of non-equilibrium models belonging to the conserved directed percolation universality class are studied. We find that at the critical point the absorbing states are hyperuniform, exhibiting anomalously small density fluctuations. The exponent characterizing the fluctuations is measured numerically, a scaling relation to other known exponents is suggested, and a new correlation length relating to this ordering is proposed. These results may have relevance to photonic band-gap materials.

description: We derive the effect of the Schrödinger--Newton equation, which can be considered as a non-relativistic limit of classical gravity, for a composite quantum system in the regime of high energies. Such meson-antimeson systems exhibit very unique properties, e.g. distinct masses due to strong and electroweak interactions. We find conceptually different physical scenarios due to lacking of a clear physical guiding principle which mass is the relevant one and due to the fact that it is not clear how the flavor wave-function relates to the spatial wave-function. There seems to be no principal contradiction. However, a nonlinear extension of the Schrödinger equation in this manner strongly depends on the relation between the flavor wave-function and spatial wave-function and its particular shape. In opposition to the Continuous Spontaneous Localization collapse models we find a change in the oscillating behavior and not in the damping of the flavor oscillation.

description: We report on the design, fabrication and characterization of superconducting coplanar waveguide resonators with nanoscopic constrictions. By reducing the size of the center line down to 50 nm, the radio frequency currents are concentrated and the magnetic field in its vicinity is increased. The device characteristics are only slightly modified by the constrictions, with changes in resonance frequency lower than 1% and internal quality factors of the same order of magnitude as the original ones. These devices could enable the achievement of higher couplings to small magnetic samples or even to single molecular spins and have applications in circuit quantum electrodynamics, quantum computing and electron paramagnetic resonance.

Machine learning for automatic malware representation and analysis

Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Malware analysis is an important research direction in the cybersecurity community. In particular, machine learning algorithms show highly promising results for the automatic analysis of malware. This thesis explores and proposes the application of machine learning for a diverse range of malware analysis such as automatic malware representation, malware feature extraction, malware detection and malware family identification. We focus on the static analysis of malware samples, specifically, the byte level n-grams of binary files for the Google's Android and Microsoft Windows platforms. The malware samples used in this thesis are all real-world samples collected from the wild. The methods are evaluated with a range of measurements to assess their effectiveness, efficiency and resiliency. We apply a random projection technique to byte n-gram term-frequency (tf ) representation and show that the new representation is equivalent to the first layer of a particular neural network (NN). This NN has an analytic solution with a non-iterative learning algorithm. We continue the malware representation exploration and extend static malware detection beyond byte level n-grams and detecting important strings. To this end, we develop a model that embeds the semantic similarity of byte level codes into a feature vector using embedding techniques. In this research path, we first propose a model (Byte2vec) with the capability of binary file feature representation and feature selection for malware detection. We show that the distance between the feature vector and its corresponding context vector provides a useful measure to rank features. Additionally, we utilize a deep Auto-encoder (AE) and show that the AE is capable of automatically learning a reasonable measure of semantic similarity within malware families. Finally, this thesis proposes a scheme that is suitable for both malware detection and malware family identification. In short, the byte n-grams 2 ≤ n ≤ 4 of both the classes.dex and AndroidManifest.xml binary files, extended from Android Apps, are pruned and selected for the classification phase. The scheme is based on the gradient boosting algorithm and outperforms a wide and diverse range of state-of-the-art methods. The scheme's F1-score for Drebin, DexShare and AMD datasets is 99.1%, 98.87% and 99.62% respectively. On average, the False Negative Rate is 2.1% for the PRAGuard dataset in which seven different obfuscation technique are implemented. In addition to fast run-time performance and resiliency against obfuscated malware, experiments show the model performs very efficiently for five zero-day families with 99.78% AUC.

description: It is shown that Kerr-Newman black holes can support linear charged scalar fields in their exterior regions. To that end, we solve analytically the Klein-Gordon wave equation for a stationary charged massive scalar field in the background of a near-extremal Kerr-Newman black hole. In particular, we derive a simple analytical formula which describes the physical properties of these stationary bound-state resonances of the charged massive scalar fields in the Kerr-Newman black-hole spacetime.

Testing solar lepton mixing sum rules in neutrino oscillation experiments

description: Small discrete family symmetries such as S4, A4 or A5 may lead to simple leading-order predictions for the neutrino mixing matrix such as the bimaximal, tribimaximal or golden ratio mixing patterns, which may be brought into agreement with experimental data with the help of corrections from the charged-lepton sector. Such scenarios generally lead to relations among the parameters of the physical leptonic mixing matrix known as solar lepton mixing sum rules. In this article, we present a simple derivation of such solar sum rules, valid for arbitrary neutrino and charged lepton mixing angles and phases, assuming only θ13^ν = θ13^e = 0. We discuss four leading-order neutrino mixing matrices with θ13^ν = 0 which are well motivated from family symmetry considerations. We then perform a phenomenological analysis of the scope to test the resulting four solar sum rules, highlighting the complementarity between next-generation neutrino oscillation experiments such as the reactor experiment JUNO and a superbeam experiment.

description: Nell’affrontare l’analisi IR dei pigmenti bianchi/inerti, affrontiamo comunque l’analisi di quattro tipi di composti chimici, Carbonati, Solfati, Silicati e Ossidi. Semplificando, possiamo dire che, i bianchi a base di Carbonato di Calcio e il Bianco di Piombo (Carbonato Basico di Piombo) sono facilmente individualizzabili tramite la banda caratteristica dei Carbonati, CO32-, cioè, quella dovuta al modo vibrazionale stretching asimmetrico nella regione 1470─1400 cm-1. Così dunque, lo spettro IR del Bianco di Piombo presenta una doppia e intensa banda a 1410─1400 cm-1, invece in quello dei bianchi a base di Carbonato di Calcio, cioè, Calcite, Aragonite e Dolomite, troviamo una sola banda, intensa, larga e ben definita attorno a 1460─1430 cm-1. Per ciò che riguarda i pigmenti/cariche a base di Solfato, SO42-, Bianco Fisso (Solfato di Bario), Litopone (Solfato di Bario e Solfuro di Zinco) e Gesso (Solfato di Calcio Biidrato), i suoi spettri IR presentano assorbimenti nella zona 1200─1050 cm-1— nella stessa regione che peraltro forniscono segnali anche i Silicati e i Fosfati — , tuttavia, i Solfati presentano picchi, dovuti al modo vibrazionale bending del legame S—O, tra 700 e 600 cm-1. Un accenno allo spettro IR del Gesso, che oltre le bande caratteristiche dei Solfati mostra anche due intensi assorbimenti dovuti allo stretching — asimmetrico e simmetrico — dell’OH– dell’acqua d’idratazione, nella regione 3550-3400 cm-1. Le due forme di Gesso — biidrato e da presa — possono essere individuate, tramite la spettrofotometria IR, senza problemi. Inoltre, si ritiene come una tecnica di analisi particolarmente adatta per l’individualizzazione delle cariche usate nella preparazione dei dipinti. D’altra parte, lo spettro IR delle cariche a base di Silicato, SiO44-, è caratterizzato da una intensa banda nella zona 1100─1000 cm-1, a causa dello stretching asimmetrico del Si―O―Si. Il Caolino (Idrossi-Silicato di Alluminio) oltre a questa banda (~1032 cm-1) ha quattro bande molto caratteristiche nella zona 3700─3620 cm-1 (OH– stretching); queste, assieme a quelle a 938 e 915─913 cm-1 (Al―O―H bending), identificano chiaramente il Caolino. Il Quarzo (Biossido di Silicio) invece può essere individuato senza problemi da un debole doppietto molto caratteristico a 798 e 780 cm-1, dovuto allo stretching simmetrico del legame Si―O―Si. Ambedue argille sono spesso presenti nelle terre come minerali associati. Per ultimo segnalare che gli Ossidi, Bianco di Titanio (Ossido di Titanio) e Bianco di Zinco (Ossido di Zinco) non hanno assorbimenti nel medio IR, con bande caratteristiche sotto 500 cm-1. Altresì, ricordiamo che i bianchi moderni sono il Bianco di Titanio, il Bianco di Zinco e il Litopone.

description: We investigate the statistics of the time taken for a system driven by recruitment to reach fixation. Our model describes a series of experiments where a population is confronted with two identical options, resulting in the system fixating on one of the options. For a specific population size, we show that the time distribution behaves like an inverse Gaussian with an exponential decay. Varying the population size reveals that the timescale of the decay depends on the population size and allows the critical population number, below which fixation occurs, to be estimated from experimental data.

Anisotropy in scattering of light from an atom into the guided modes of a nanofiber

description: We study the scattering of guided light from a multilevel cesium atom with the transitions between the hyperfine levels $6S_{1/2}F=4$ and $6P_{3/2}F'=5$ of the $D_2$ line into the guided modes of a nanofiber. We show that the rate of scattering of guided light from the atom in the steady-state regime into the guided modes is asymmetric with respect to the forward and backward directions and depends on the polarization of the probe field. The asymmetry between the forward and backward scattering is a result of the complex transition structure of the atom and the existence of a longitudinal component of the guided-mode profile function. In the case of a two-level atom, the rates of spontaneous emission (and consequently the rates of scattering) into the forward and backward guided modes differ from each other when the atomic dipole matrix-element vector is a complex vector in the plane that contains the fiber axis and the atomic position.
