Mathematical Properties of Dynamic Systems and the Foundations of Quantum Theory

While it is widely acknowledged that quantum theory is strange, and that the world view it implies is elusive, there is considerably less consensus as to why this is the case. This article will explore the possibility that the theory may be opaque because the mathematical language it employs is inarticulate. To address this possibility, three interconnected mathematical theories will be developed, each specifically designed to handle aspects of quantum theory’s subject matter. The first will describe dynamic systems in terms that are general enough to be applicable to any kind dynamics, including both classical and quantum. That description will then be used to construct a theory of experiments, with the aim of understanding what types of experiments scientific methodology allows. Finally, the theory of experiments will found a theory of experimental probabilities applicable to any collection of experiments, so long as their probabilities are internally consistent. The resulting over-arching mathematical language will then be applied to quantum physics. In the initial application, it will be used to explain the core nature and structure of quantum measurement and probability. Following that, it will be used to construct a large class of conceptually simple systems that are capable of displaying the full range of quantum behavior. The properties that define this class of systems will be in accord with experimental results, leaving open the possibility that the physical universe may be describable as such a system. The more immediate conclusion, however, will be that systems that posses quantum behavior may be neither strange nor elusive.
STOP MEASLES NOW Increasing Measles Vaccine Coverage through Training of Health Workers

HIGH BURDEN OF MEASLES IN THE PHILIPPINES Measles is the leading cause of death globally among vaccine-preventable diseases of children, due to its complications such as diarrhea, otitis media, pneumonia, and encephalitis, among others [1]. About 44% of 1.7 million vaccine-preventable deaths are attributed to measles among children worldwide annually, mostly in countries or regions where vaccine coverage is low [2].
Peppermint ( Mentha piperita ) extract modulates the genotoxic effects of Cypermethrin and Malathion insecticides on Allium cepa root cells

and metaphase arrest. Both insecticides induced a concentration dependent MAs ranged between 19.0 and 29.6%. MAs and TAs of cypermethrin were significant at the high dose, while those caused by malathion were significant at both medium and high doses. Aberrations observed included; bridges, vagrants, laggards, stickiness, multipolar, binucleated cells, micronuclei, lobed, blebbed and vacuolated nuclei. Application of peppermint water extract to both insecticides reduced the cytotoxic and genotoxic capacity of these insecticides.
High Dose of FGF-2 Induced Growth Retardation via ERK1/2 De-phosphorylation in Bone Marrow-derived Mesenchymal Stem Cells

Fibroblast growth factor (FGF)-2 is one of the most effective growth factors to increase the growth rate of mesenchymal stem cells (MSCs). Previously, we reported that low dose of FGF-2 (1 ng/ml) induced proliferation of bone marrow-derived mesenchymal stem cells (BMSCs) through AKT and ERK activation resulting in reduction of autophagy and senescence, but not at a high dose. In this study, we investigated the effects of high dose FGF-2 (10 ng/ml) on proliferation, autophagy and senescence of BMSCs for long term cultures (i.e., 2 months). FGF-2 increased the growth rate of BMSCs in a dose dependent manner for a short term (3 days), while during long term cultures (2 months), population doubling time was increased and accumulated cell number was lower than control in BMSCs when cultured with 10 ng/ml of FGF-2. 10 ng/ml of FGF-2 induced immediate de-phosphorylation of ERK1/2, expression of LC3-II, and increase of senescence associated β-galactosidase (SA-β-Gal, senescence marker) expression. In conclusion, we showed that 10 ng/ ml of FGF-2 was inadequate for ex vivo expansion of BMSCs because 10 ng/ml of FGF-2 induced growth retardation via ERK1/2 de-phosphorylation of autophagy senescence in
Relaxed observer-based controller design method of discrete-time multiplicative noised LPV systems via an extended projective lemma

ABSTRACT The aim of this paper is to discuss a relaxed observer-based control problem of multiplicative noised Linear Parameter Varying (LPV) systems with unmeasurable states. For discussing the problem, positive definite matrices without neglecting any element are employed to construct a novel parameter-dependent Lyapunov function. Based on the Lyapunov function, some relaxed sufficient conditions are derived to hold the freedom in searching feasible solutions. Furthermore, an extended projective lemma is developed to convert those conditions into Linear Matrix Inequality (LMI) form. Solving these LMI conditions, controller gain and observer gain can be simultaneously obtained in one-step procedure via using convex optimization algorithm. Therefore, an observer-based controller can be established to guarantee the asymptotical stability of the multiplicative noised LPV systems in the sense of mean square. At last, two numerical examples are used to show effectiveness and applicability of the proposed design method.
SUPERVISED CONTRASTIVE LEARNING FOR PRE-TRAINING BIOACOUSTIC FEW-SHOT SYSTEMS

We show in this work that learning a rich feature extractor from scratch using only official training data is feasible. We achieve this by learning representations using a supervised contrastive learning framework. We then transfer the learned feature extractor to the sets of validation and test for few-shot evaluation. For few-shot validation, we simply train a linear classifier on the negative and positive shots and obtain a F-score of 63.46% outperforming the baseline by a large margin. We don’t use any external data or pretrained model. Our approach doesn’t require choosing a threshold for prediction or any post-processing technique. Our code is publicly available on Github : https://github.com/ ilyassmoummad/dcase23_task5_scl
ANTENNA WITH

: In this article, we have described a novel ultra-wide-band (UWB) monopole antenna with two symmetrical strips for wireless UWB communications. The proposed antenna consists of a center monopole, two symmetrical strips having one step on the strip, and CPW feeding. Three techniques (one monopole and two strips, symmetrical structure, and step on the strip) are used to produce the multiple resonance and low dispersion. The proposed UWB antenna has an omnidirectional radiation pattern

An Objective No-Reference Measure of Illumination Assessment

Abstract Illumination problems have been an important concern in many image processing applications. An important issue in the field of illumination enhancement is absence of a quantitative measure for assessment of illumination of an image. In this research work a quantitative measure indicating the illumination state, i.e. contrast level and brightness of an image is also proposed. The measure utilises the estimated Gaussian distribution of the input image and the Kullback-Leibler Divergence between the estimated Gaussian distribution and the desired Gaussian distribution to calculate the quantitative measure. The experimental results show the effectiveness and the reliability of proposed illumination assessment measure.
Neuropsychologie bipolarer Störungen

In this article the contribution of neuropsychological research for a better understanding of the psychopathology of mood disor− ders is reviewed. First, the broad spectrum of bipolar disorders is described. Second, a selective review of important results of neuropsychological studies with patients with mood disorders is presented. Although several methodological problems limit the interpretation of the findings, there is evidence that patients with a bipolar disorder show a consistent impairment in atten− tion, memory/learning and executive functions.
Infinite densities in continuous-time random walks

We study occupation time statistics in ergodic continuous-time random walks. Under thermal detailed balance conditions, the average occupation time is given by the Boltzmann-Gibbs canonical law. The finite-time fluctuations around this mean turn out to exhibit dual time scaling and distribution laws. The infinite density of large fluctuations complements the Levy-stable density of bulk fluctuations. Neither of the two should be interpreted as a stand-alone limiting law, as each has its own deficiency: the infinite density has an infinite norm (despite particle conservation), while the stable distribution has an infinite variance (although occupation times are bounded). These unphysical divergences are remedied by consistent use and interpretation of both formulas. Interestingly, while the system’s canonical equilibrium laws naturally determine the mean occupation time of the ergodic motion, they also control the infinite and stable densities of fluctuations.
Combined Quantum Kinetic and Rate Equations Modeling of the Non-Equilibrium Carrier Dynamics of Matter Exposed to X-Ray Laser Pulses

Nanoplasma generation in neon clusters irradiated by intense X-ray femtosecond laser pulse is described using a generalized Maxwell Boltzmann Bloch quantum-kinetic formalism coupled self-consistently with rate equations which describe the creation of unoccupied atomic core levels. The generation of dense hot plasma environment lasting longer than the driving laser pulse together with the simultaneous creation of unoccupied core levels is studied as an initial step to explore the process of nuclear excitation by electron capture. The results describing the microscopic laser-induced carrier dynamics and the secondary interaction of the emitted soft X-rays with the perturbed clusters might provide essential insights on the triggering conditions of this exotic nuclear excitation mechanism.
Non linear parametric mode regression

ABSTRACT In this article, we propose a semi-parametric mode regression for a non linear model. We use an expectation-maximization algorithm in order to estimate the regression coefficients of modal non linear regression. We also establish asymptotic properties for the proposed estimator under assumptions of the error density. We investigate the performance through a simulation study.
Spall fracture and twinning in laser shock-loaded single-crystal magnesium

As a major failure process in materials subjected to dynamic loading, spall fracture is one of the most widely studied issues in shock physics. To investigate its dependence on the microstructure, including both initial and shock-induced features, laser shock experiments were performed on single crystal magnesium. Shock loading was applied in directions parallel and perpendicular to the c-axis of the crystals. Both the spall strength and the fracture surface morphology are found to depend on the direction of the shock application with respect to crystal orientations. The results complement data obtained previously over ranges of lower strain rates. A detailed analysis of the residual microstructure and crack patterns in the recovered samples shows strong correlations between damage localization and twins, both pre-existing and shock-induced. Thus, cracks match specific twinning directions, which is discussed on the basis of deformation mechanisms reported under quasi-static loading conditions, either pris.
Propagation and linear mode conversion of magnetosonic and electromagnetic ion cyclotron waves in the radiation belts

Magnetosonic waves and electromagnetic ion cyclotron (EMIC) waves are important for electron acceleration and loss from the radiation belts. It is generally understood that these waves are generated by unstable ion distributions that form during geomagnetically disturbed times. Here we show that magnetosonic waves could be a source of EMIC waves as a result of propagation and a process of linear mode conversion. The converse is also possible. We present ray tracing to show how magnetosonic (EMIC) waves launched with large (small) wave normal angles can reach a location where the wave normal angle is zero and the wave frequency equals the so‐called crossover frequency whereupon energy can be converted from one mode to another without attenuation. While EMIC waves could be a source of magnetosonic waves below the crossover frequency, magnetosonic waves could be a source of hydrogen band waves but not helium band waves.
Lewy body Demenz und Differenzialdiagnostik - Demenzielle Erkrankungen mit begleitender Parkinson-Symptomatik

B ereits im Frühstadium der AD ist häufig eine motorische Verlangsamung beobachtbar (4). Diskrete extrapyramidale Symptome wie Hypomimie, monotone Sprache oder Haltungsveränderungen können die Entwicklung einer Demenz ankündigen oder bereits früh im Krankheitsverlauf auftreten. Im weiteren Verlauf kommt es bei etwa 30% der AD-Patienten zum Auftreten extrapyramidaler Symptome im Sinne eines Parkinson-Syndroms mit Bradykinese, Rigor oder Tremor (3). Darüber hinaus ist zu erwähnen, dass AD-Patienten, die eine deutliche Bradykinesie zeigen, bei einer Behandlung mit Neuroleptika unter häufigeren und stärker ausgeprägten extrapyramidal-motorischen Symptomen leiden (2).
Robust H∞ control design of an electromagnetic actuated active suspension considering the structure non-linearity

Electromagnetic actuated active suspension (EAAS) benefits energy harvesting while providing active control. However, the inertia of the actuator introduces an equivalent mass coupled with the sprung and unsprung mass. In addition, the specific structure of the suspension features structure non-linearity, which results in the perturbation of the equivalent mass of the actuator, the variation of the transmission ratio of the actuator output torque to the actuator force at the wheel side and an extra force to be compensated with. A dynamic model of active control considering the equivalent mass and the structure non-linearity is proposed. Based on a gearbox type EAAS, respective non-linearity is studied. For multi-objective optimization, a robust controller is designed with proper weighting functions. A virtual prototype of the EAAS is built and simulated with a bump/pothole and random excitation road profiles. Results show that neglecting the structure non-linearity effects influences the accuracy of active control. The investigation of this paper provides a fundamental methodology for the control design of actual applications of EAASs.
On verifying validity of quantum computations for BQP

Recently proposed schemes for verifying quantum computations in the `high complexity' regime i.e. beyond the remit of classical computers, have been based on adaptations of the classical theory of interactive proof systems (IP). These schemes remarkably provide confidence against arbitrarily malicious adversarial behaviour in the misfunctioning of the quantum computing device in the course of the verification protocol. Here we propose a different verification scheme which although not secure against arbitrarily adversarial behaviour, may nevertheless be sufficiently acceptable in many practical situations. Our scheme is far simpler than the IP based schemes, and in contrast to them, our verifier is entirely classical. It is based on the fact that adaptive Clifford circuits on general product state inputs provide universal quantum computation, while the same processes without adaptation are always classically efficiently simulatable.

Globally Optimal Multivariate Splines: Optimizing B-coefficient and vertex coordinates of simplex splines using interval analysis

In applications like model identification accurate methods for data approximation are required. Multivariate simplex B-splines form a class of nonlinear function approximators capable of approximating scattered data. Simplex B-splines are piecewise polynomials defined on a triangulation. Currently, data approximation using simplex B-splines is done by optimizing the B-coefficients of the spline function, without optimizing the triangulation. Triangulation optimization is a standing problem of function approximation using simplex splines. Recently the Interspline was presented, an interval extension of simplex splines with interval B-coefficients defined on a triangulation with interval vertices. Using Intersplines guaranteed global optimization of the vertices of the triangulation and the B-coefficients is possible. However, until now this method was only applicable for optimization of univariate and bivariate linear simplex B-splines on very specific triangulations. The contribution of this work is a method for guaranteed global optimization of vertices and B-coefficients of $n$-variate linear simplex splines with zero order continuity on general triangulations. This partly solves the triangulation optimization problem for simplex splines. Using this method data can be approximated more accurately, while the triangulation stays the same size.
(k, p)-Planarity: A Generalization of Hybrid Planarity

A graph $G$ is $(k,p)$-planar if its vertices can be partitioned into clusters of size at most $k$ such that $G$ admits a drawing where: (i) Each cluster is associated with a closed region in the plane (called cluster region) that is topologically equivalent to a disk; (ii) Cluster regions are pairwise disjoint; (iii) Each vertex of a cluster is associated with at most $p$ distinct points (called ports) on the boundary of its cluster region; (iv) Each edge $(u,v)$ is a Jordan arc connecting a port of $u$ with a port of $v$; and (v) Edges connecting different clusters do not cross each other and do not intersect any cluster region, with the only exception for end-points. We first ask a Tur\'{a}n-type question and give a tight upper bound on the number of edges of $(k,p)$-planar graphs. We then study the complexity of the $(k,p)$-planarity testing problem and prove that $(4,1)$-planarity testing and $(2,2)$-planarity testing are both NP-complete problems. Finally, motivated by the NP-completeness of $(2,2)$-planarity testing, we investigate the combinatorial properties of $(2,2)$-planar graphs and study their relationship with $1$-planar graphs, describing families of $1$-planar graphs that are $(2,2)$-planar as well as families that are not.
Term structure of interest rates with stickiness: a subdiffusion approach

In this paper, we propose a new class of term structure of interest rate models which is built on the subdiffusion processes. We assume that the spot rate is a function of a time changed diffusion process belonging to a symmetric pricing semigroup for which its spectral representation is known. The time change process is taken to be an inverse Levy subordinator in order to capture the stickiness feature observed in the short-term interest rates. We derive the analytical formulas for both bond and bond option prices based on eigenfunction expansion method. We also numerically implement a specific subdiffusive model by testing the sensitivities of bond and bond option prices with respect to the parameters of time change process.
Computergestütztes Screening kognitiver Beeinträchtigungen - Ergebnisse einer Validierungsstudie zum Programm „Kopfsache Interaktiv”

Mit Unterstutzung der BKK BMW fuhrten uber tausend Mitarbeiterinnen und Mitarbeiter der BMW Werke Dingolfing zusammen mit psychometrischen Tests das Programm „Kopfsache interaktiv” durch. Die Untersuchung diente der Ermittlung von Referenzwerten fur die Leistungen gesunder, im Arbeitsprozess stehender Menschen. Die Untersuchungsergebnisse belegen, dass „Kopfsache interaktiv” als Awareness und Screening-Programm zur Erfassung leichter kognitiver Defizite in den Bereichen der Aufmerksamkeits- und Gedachtnisleistungen geeignet ist. Die ermittelten Durchschnittsleistungen wurden als Grundlage fur eine erste Normierung genutzt. Die positiven Ruckmeldungen der Untersuchungsteilnehmer belegen die hohe Akzeptanz des Programms. Supported by the medical insurance company (BKK) of the German car manufacturer BMW more than 1000 employees of the BMW factories in Dingolfing participated voluntarily in the psychometric screening study „Kopfsache interaktiv”. This study was initiated to obtain reference values concerning the cognitive performance of healthy controls, who are still engaged in their regular job and working activities. The results clearly demonstrate that „Kopfsache interaktiv” can be used as an awareness tool and also as a screening instrument for the assessment of mild cognitive deficits in memory and attention. The collected data, the mean scores and standard deviations served as a basis for setting up norm values. The positive feedback which we obtained from the study participants proves very well the general acceptance of the „Kopfsache interaktiv” program.
Towards the Understanding of Turbulence

In a previous paper, the author proposed turbulence as a second order phase transition with spontaneous broken symmetry. This has been experimentally confirmed by research groups from the University of Illinois and Weizemann Institute of Science. In this paper we propose turbulence as a classical analog of Bose Einstein condensate and the Gross-Pitaevskii equation is used to derive the condensation free energy. The critical value of the order parameter, the condensation wave function is determined. This is the value where turbulence occurs and spontaneous symmetry breaking in the ground state of the condensation free energy takes place. Being a condensate, there is molecular pairing in turbulence. We determine the numerical value of the condensation free energy with the use of the coupled oscillation model for the pair of molecules. Our expression for the condensation free energy also yields a power series in terms of the order parameter in agreement with the Landau phenomenology of second order phase transition. This confirms that turbulence is a condensate since Gross-Pitaevskii equation is the equation for condensate. We conclude that our understanding of turbulence is a second order phase transition and is a condensate with molecular pairing.
