Two A. N. Kolmogorov's Early Letters About Mathematics Education
Creators: name: B. V. Gnedenko
Publisher: name: Reliability: Theory & Applications
Year: 2018

description: It is well known that A.N. Kolmogorov made a great contribution to the development of Russian mathematics pedagogy. Mr. Kolmogorov became increasingly interested in pedagogical issues in early 1962, when he came up with many new ideas that encouraged teachers and mathematicians to use their creativity in search of ways to solve these issues. Those ideas were set forth in the letters I received from Mr. Kolmogorov in 1962. My son came across two of them while sorting out books and papers, and both of them deserve publication. We will present the part of the letters devoted to the topic of our discussion in full. The publication takes the reader to the early 1960s and introduces him or her to Andrey Nikolaevich Kolmogorov's vision of mathematics education at schools and universities (particularly at the faculties of mathematics, physics, chemistry, and at physics and technology institutes, as well as at engineering and physics institutes).

description: In this expository paper, we review a recent progress of the study of the Diederich--Fornaess index of complex domains with emphasis on the case of domains with Levi-flat boundary. It is exhibited that for any compact Levi-flat real hypersurface, the norm of its infinitesimal holonomy must exceed the curvature of its normal bundle at a point.

description: In this paper, a hyperparameter tuning based Bayesian optimization of digital twins is carried out to diagnose various faults in grid connected inverters. As fault detection and diagnosis require very high precision, we channelize our efforts towards an online optimization of the digital twins, which, in turn, allows a flexible implementation with limited amount of data. As a result, the proposed framework not only becomes a practical solution for model versioning and deployment of digital twins design with limited data, but also allows integration of deep learning tools to improve the hyperparameter tuning capabilities. For classification performance assessment, we consider different fault cases in virtual synchronous generator (VSG) controlled grid-forming converters and demonstrate the efficacy of our approach. Our research outcomes reveal the increased accuracy and fidelity levels achieved by our digital twin design, overcoming the shortcomings of traditional hyperparameter tuning methods.

description: For optimization of engineering production, it is proposed to use a system of quick changeover (SMED). The introduction of this approach will enhance, in particular, the increment of the coefficient of technical use of equipment A (availability factor) by reducing non-productive time downtime. In this case, A is used as the optimization parameter. Examples of technical decisions applying SMED are presented.
A reconstruction method for anisotropic universes in unimodular $F(R)$-gravity

description: An extension of unimodular Einsteinian gravity in the context of $F(R)$ gravities is used to construct a class of anisotropic evolution scenarios. In unimodular GR the determinant of the metric is constrained to be a fixed number or a function. However, the metric of a generic anisotropic universe is not compatible with the unimodular constraint, so that a redefinition of the metric, to properly take into account the constraint, need be performed. The unimodular constraint is imposed on $F(R)$ gravity in the Jordan frame by means of a Lagrangian multiplier, to get the equations of motion. The resulting equations can be viewed as a reconstruction method, which allows to determine what function of the Ricci scalar can realize the desired evolution. For the sake of clarity, some characteristic examples are invoked to show how this reconstruction method works explicitly. The de Sitter spacetime here considered, in the context of unimodular $F(R)$ gravity, is suitable to describe both the early- and late-time epochs of the universe history.

description: We analyse some PT-symmetric oscillators with $T_{d}$ symmetry that depend on a potential parameter $g$. We calculate the eigenvalues and eigenfunctions for each irreducible representation and for a range of values of $g$. Pairs of eigenvalues coalesce at exceptional points $g_c$; their magnitude roughly decreasing with the magnitude of the eigenvalues. It is difficult to estimate whether there is a phase transition at a nonzero value of $g$ as conjectured in earlier papers. Group theory and perturbation theory enable one to predict whether a given space-time symmetry leads to real eigenvalues for sufficiently small nonzero values of $g$.

description: Ο σκοπός της παρούσας έρευνας ήταν: α) Να εξετάσει τα επίπεδα της επαγγελματικής ικανοποίησης, της ασάφειας και σύγκρουσης ρόλων των εργαζόμενων της Ολυμπιακής εγκατάστασης Κωπηλασίας την περίοδο πριν την έναρξη της Ολυμπιακής Λεμβοδρομίας, β) να εξετάσει τη σχέση ανάμεσα στην επαγγελματική ικανοποίηση και τη σύγκρουση και ασάφεια ρόλων και γ) να διερευνήσει το ρυθμιστικό ρόλο της αυτονομίας στις προαναφερθείσες σχέσεις. Το δείγμα της έρευνας αποτέλεσαν 100 εργαζόμενοι {Ν=100) στο Κωπηλατοδρόμιο με μέσο όρο ηλικίας Μ. Ο. = 29.66 έτη (Τ.Α. = 4.85). Για τη μέτρηση της επαγγελματικής ικανοποίησης χρησιμοποιήθηκε το ερωτηματολόγιο Καταγραφής της Επαγγελματικής Ικανοποίησης (ESI, Koustelios & Bagiatis, 1997), για τη μέτρηση της ασάφειας και σύγκρουσης ρόλων χρησιμοποιήθηκαν οι κλίμακες των Rizzo, House & Lirtzman (1970) και για τη μέτρηση της αυτονομίας οι κλίμακες του Beehr (1976). Από τα αποτελέσματα φάνηκε ότι οι εργαζόμενοι ήταν ικανοποιημένοι από τον προϊστάμενο, τη φύση της εργασίας, τις συνθήκες εργασίας και το μισθό, λιγότερο από τον Οργανισμό και δυσαρεστημένοι από τις ευκαιρίες προαγωγής. Τα επίπεδα της σύγκρουσης ρόλων βρέθηκαν υψηλά, της αυτονομίας σχετικά υψηλά και της ασάφειας χαμηλά. Από την ανάλυση πολλαπλής παλινδρόμησης φάνηκε ότι υπάρχει αρνητική σχέση ανάμεσα στη σύγκρουση και την ασάφεια ρόλων με όλες τις διαστάσεις της επαγγελματικής ικανοποίησης. Από την ιεραρχική ανάλυση παλινδρόμησης επιβεβαιώθηκε ρυθμιστικός ρόλος της αυτονομίας μόνο στη σχέση της σύγκρουσης ρόλων με την ικανοποίηση από τη φύση της εργασίας, με τη μορφή της εξασθένησης των αρνητικών επιδράσεων της σύγκρουσης ρόλων στην ικανοποίηση, όταν εργασία παρέχει χαμηλή και μεσαία αυτονομία και της αντιστροφής της αρνητικής επίδρασης της σύγκρουσης ρόλων σε εργασίες υψηλής αυτονομίας.

description: We introduce a proposal to prepare spin-obit maximally discordant mixed states by a linear optical circuit, with quantum bits (qubits) encoded in the polarization and transverse mode degrees of freedom of photons. In particular, we discuss how to prepare non-balanced spin-orbit entangled states, applying this technique to obtain maximally discordant mixed states. We present a simulation of the optical circuit by using the Jones matrix formalism. We performed a study of entanglement, classical and quantum correlations. The results show excellent agreement with the underlying theory and open a new experimental approach for addressing quantum correlations in optical setups.

Modeling and simulation of a quantum thermal noise on the qubit

Publisher: name: arXiv
Year: 2022
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Quantum noise or decoherence is a major factor impacting the performance of quantum technologies. On the qubit, an important quantum noise, often relevant in practice, is the thermal noise or generalized amplitude damping noise, describing the interaction with a thermal bath at an arbitrary temperature. A qubit thermal noise however cannot be modeled nor directly simulated with a few elementary Pauli operators, but instead requires specific operators. Our main goal here is to construct a circuit model for simulating the thermal noise from standard elementary qubit operators. Starting from a common quantum-operation model based on Kraus operators and an associated qubit-environment model, we derive a proper Stinespring dilated representation for the thermal noise. This dilated unitary model is then decomposed in terms of simple elementary qubit operators, and converted into a circuit based on elementary quantum gates. We arrive at our targeted simulator circuit for the thermal noise, coming with built-in easy control on the noise parameters. The noise simulator is then physically implemented and tested on an IBM-Q quantum processor. The simulator represents a useful addition to existing libraries of quantum circuits for quantum processors, and it offers a new tool for investigating quantum signal and information processing having to cope with thermal noise.

description: We follow the ideas of measuring strength of dependence between random events, presented at two previous MMR conferences in South Africa and Tokyo. In our work here we apply it for analyzing local dependence structure of some popular bivariate distributions. At the Grenoble conference presentation we focus on the Bivariate Normal distributions with various correlation coefficients, and on the Marshal-Olkin distribution with various parameter’s combinations. We draw the surface z = gii(x,y), i=1,2 of dependence of i-th component on the other component j≠i within the squares [x, x +1]x[y,y+1], and [x, x +.5]x[y,y+.5]. The points (x,y) run within the square [-3.5, 3.5]x[-3.5, 3.5] for Bivariate Normal distribution, and in [0.10]x[0,10] for the Marshal-Olkin distribution.

Το κύριο σήμα που βοηθά στο καθορισμό του μεγέθους της ενεργειακής πρόσληψης, δίδεται από τη λεπτίνη και αυτό καθορίζεται από τις διαθέσιμες αποθήκες ενέργειας στον οργανισμό. Στη νοσογόνο παχυσαρκία, αυτή η δράση της λεπτίνης παρακωλύεται, μία κατάσταση που ονομάζεται αντίσταση στην λεπτίνη. Από την ανακάλυψη της λεπτίνης το 1994, γίνονται προσπάθειες για την αποσαφήνιση του ρόλου του πεπτιδίου αυτού σε πειραματόζωα και ανθρώπους. Μέσω των ραδιοανασολογικών μεθόδων (Radio immunoassay - RIA), έχουν συγκεντρωθεί σημαντικά δεδομένα από κλινικές μελέτες σε ότι αφορά στη σχέση της λεπτίνης με ανθρωπομετρικούς, μεταβολικούς και ορμονικούς παράγοντες, τόσο σε φυσιολογικό όσο και σε παθοφυσιολογικό επίπεδο. Τα επίπεδα της στον ορό είναι αυξημένα επί νοσογόνου παχυσαρκίας, γεγονός που φυσιολογικά θα έπρεπε να συνδυάζεται με μειωμένη πρόσληψη τροφής. Στη βιβλιογραφία φαίνεται πως υπάρχει ομοφωνία στο ότι τα επίπεδα ορού της λεπτίνης συνδέονται με την λιπώδη μάζα σώματος, ωστόσο η σχέση αυτή εξηγεί μερικώς την ποικιλομορφία στα επίπεδα ορού λεπτίνης. Πολλές προσπάθειες καταβάλλονται για την διαλεύκανση των παραγόντων που ρυθμίζουν τη συγκέντρωση της στον ορό, και κατά συνέπεια για την διαλεύκανση του παθοφυσιολογικού ρόλου της στη νοσογόνο παχυσαρκία. Τα αποτελέσματα επί του παρόντος είναι αντιφατικά, πιθανώς λόγω της μεγάλης ετερογένειας και του μεγάλου εύρους του δείκτη μάζα σώματος (ΔΜΣ) των ασθενών καθώς και τις διαφορές τους σε επίπεδο πληθυσμού, στις διάφορες μελέτες. Στη παρούσα μελέτη, εξετάστηκε η συσχέτιση, σε μία ομάδα ασθενών με διαφορετικούς δείκτες μάζας σώματος, των επιπέδων λεπτίνης στον ορό, με ανθρωπομετρικούς και παθοβιοχημικούς δείκτες και έγινε διερεύνηση της σχέσης των τιμών λεπτίνης αίματος με βιοχημικούς δείκτες που σχετίζονται με την εκδήλωση φλεγμονωδών παθήσεων και την ανάπτυξη καρδιαγγειακών νοσημάτων.

description: We consider a generalization of the classical pinning problem for integer-valued random walks conditioned to stay non-negative. More specifically, we take pinning potentials of the form $\sum_{j\geq 0}ε_j N_j$, where $N_j$ is the number of visits to the state $j$ and $\{ε_j\}$ is a non-negative sequence. Partly motivated by similar problems for low-temperature contour models in statistical physics, we aim at finding a sharp characterization of the threshold of the wetting transition, especially in the regime where the variance $σ^2$ of the single step of the random walk is small. Our main result says that, for natural choices of the pinning sequence $\{ε_j\}$, localization (respectively delocalization) occurs if $σ^{-2}\sum_{ j\geq0}(j+1)ε_j\geqδ^{-1}$ (respectively $\le δ$), for some universal $δ<1$. Our finding is reminiscent of the classical Bargmann-Jost-Pais criteria for the absence of bound states for the radial Schrödinger equation. The core of the proof is a recursive argument to bound the free energy of the model. Our approach is rather robust, which allows us to obtain similar results in the case where the random walk trajectory is replaced by a self-avoiding path $γ$ in $\mathbb Z^2$ with weight $\exp(-β|γ|)$, $|γ|$ being the length of the path and $β>0$ a large enough parameter. This generalization is directly relevant for applications to the above mentioned contour models.

description: Richness and complexity of Raman spectra related to graphene materials is established from years to decades, with, among others: the well-known G, D, 2D,... bands plus a plethora of weaker bands related to disorder behavior, doping, stress, crystal orientation or stacking information. Herein, we report on how to detect crumpling effects in Raman spectra, using a large variety of few and multilayer graphene. The main finding is that these crumples enhance the G band intensity like it does with twisted bi layer graphene. We updated the D over G band intensity ratio versus G band width plot, which is generally used to disentangle point and linear defects origin, by reporting surface defects created by crumples. Moreover, we report for the first time on the existence 23 resonant additional bands at 633 nm. We attribute them to edge modes formed by high density of crumples. We use Raman plots (2D bands versus G band positions and widths) to gain qualitative information about the way layers are stacked.

description: The effects of electron (Ir) and hole (Re) doping on the hybridization gap and antiferromagnetic order have been studied by magnetization, muon spin relaxation ($μ^+$SR), and inelastic neutron scattering on the polycrystalline samples of Ce(Os$_{1-x}$Ir$_x$)$_2$Al$_{10}$ ($x$ = 0.08 and 0.15) and CeOs$_{1.94}$Re$_{0.06}$Al$_{10}$. $μ^+$SR spectra clearly reveals magnetic ordering below 20 and 10 K for $x$ = 0.08 and 0.15 samples respectively with a very weak signature of oscillations of the muon initial asymmetry at very short time scale. Our important findings are that small amount of electron doping (i) completely suppress the inelastic magnetic excitations near 11 meV down to 2K, which were observed in the undoped compound, and the response transforms into a broad quasielastic response and (ii) the internal field at the corresponding muon site is remarkably enhanced by about ten times compared with the parent compound. On the other hand with small amount of hole (3\% Re) doping the intensity of the inelastic magnetic excitations near 11 meV is reduced significantly. The main origin of the observed doping effect is an extra 5$d$ electrons being carried by Ir and a hole carried by Re compared with that the Os atom. The obtained results demonstrate a great sensitivity of the carrier doping and provides additional ways to study their anomalous magnetic properties.

description: Έρευνες στο χώρο της ψυχολογίας της άσκηση, αποδεικνύουν το σημαντικό ρόλο της φυσικής δραστηριότητας στον περιορισμό του άγχους και στη μείωση της κατάθλιψης. Η συμβολή της φυσικής δραστηριότητας είναι πολλαπλή και ουσιαστική όχι μόνο σε φυσιολογικούς πληθυσμούς αλλά και σε κλινικούς και συγκεκριμένα σε άτομα που πάσχουν από συναισθηματικές και αγχώδεις διαταραχές. Σκοπός της παρούσας έρευνας ήταν να διερευνήσει αν και σε ποιο βαθμό ένα συγκεκριμένο πρωτόκολλο αερόβιας άσκησης (περπάτημα 30 λεπτών, 3 φορές εβδομαδιαίως για 8 εβδομάδες), σε συνδυασμό με ένα πρόγραμμα καθορισμού στόχων, επιδρά στα συμπτώματα άγχους και κατάθλιψης σε άτομα που πάσχουν από αγχώδεις ή/ και συναισθηματικές διαταραχές. Στην έρευνα συμμετείχαν, 10 γυναίκες και 3 άνδρες, με Μ.Ο. ηλικίας 39.69 έτη και Τ.Α.=10, που έπασχαν από αγχώδεις ή/ και συναισθηματικές διαταραχές. Εξετάστηκε η επίδραση της άσκησης στα συμπτώματα του άγχους και της κατάθλιψης μετά την εφαρμογή του προγράμματος παρέμβασης. Τα αποτελέσματα έδειξαν ότι η εφαρμογή ενός προγράμματος άσκησης με τη βοήθεια ενός προγράμματος στόχων (με τη χρήση πεδομέτρων), βοηθάει σημαντικά στη μείωση του άγχους και στη βελτίωση της διάθεσης σε άτομα που πάσχουν από ήπιας και μέτριας μορφής αγχώδεις ή/ και συναισθηματικές διαταραχές.

description: This paper presents discrete convex analysis as a tool for economics and game theory. Discrete convex analysis is a new framework of discrete mathematics and optimization, developed during the last two decades. Recently, it is being recognized as a powerful tool for analyzing economic or game models with indivisibilities. The main feature of discrete convex analysis is the distinction of two convexity concepts, M-convexity and L-convexity, for functions in integer or binary variables, together with their conjugacy relationship. The crucial fact is that M-concavity, or its variant called M-natural-concavity, is equivalent to the (gross) substitutes property in economics. Fundamental theorems in discrete convex analysis such as the M-L conjugacy theorems, discrete separation theorems and discrete fixed point theorems yield structural results in economics such as the existence of equilibria and the lattice structure of equilibrium price vectors. Algorithms in discrete convex analysis give iterative auction algorithms as well as computational methods for equilibria.

description: A proposal to describe gravity duals of conformal theories with boundaries (AdS/BCFT correspondence) was put forward by Takayanagi few years ago. However interesting solutions describing field theories at finite temperature and charge density are still lacking. In this paper we describe a class of theories with boundary, which admit black hole type gravity solutions. The theories are specified by stress-energy tensors that reside on the extensions of the boundary to the bulk. From this perspective AdS/BCFT appears analogous to the fluid/gravity correspondence. Among the class of the boundary extensions there is a special (integrable) one, for which the stress-energy tensor is fluid-like. We discuss features of that special solution as well as its thermodynamic properties.

description: Feature lines are important geometric cues in characterizing the structure of a CAD model. Despite great progress in both explicit reconstruction and implicit reconstruction, it remains a challenging task to reconstruct a polygonal surface equipped with feature lines, especially when the input point cloud is noisy and lacks faithful normal vectors. In this paper, we develop a multistage algorithm, named RFEPS, to address this challenge. The key steps include (1)denoising the point cloud based on the assumption of local planarity, (2)identifying the feature-line zone by optimization of discrete optimal transport, (3)augmenting the point set so that sufficiently many additional points are generated on potential geometry edges, and (4) generating a polygonal surface that interpolates the augmented point set based on restricted power diagram. We demonstrate through extensive experiments that RFEPS, benefiting from the edge-point augmentation and the feature-preserving explicit reconstruction, outperforms state-of-the-art methods in terms of the reconstruction quality, especially in terms of the ability to reconstruct missing feature lines.

description: We reported an electro-hydrodynamic shooting phenomenon of liquid metal stream. A small voltage direct current electric field would induce ejection of liquid metal inside capillary tube and then shooting into sodium hydroxide solution to form discrete droplets. The shooting velocity has positive relationship with the applied voltage while the droplet size is dominated by the aperture diameter of the capillary nozzle. Further, the motion of the liquid metal droplets can be flexibly manipulated by the electrodes. This effect suggests an easy going way to generate metal droplets in large quantity, which is important from both fundamental and practical aspects.

description: Σκοπός της έρευνας ήταν να διερευνήσει την αποτελεσματικότητα δύο διαφορετικών διαλειμματικών προπονήσεων, της μικρής διάρκειας (30sec ομάδα Α) και της μέσης διάρκειας (2.5-4min ομάδα Β) όσον αφορά τις καρδιοαναπνευστικές προσαρμογές [μέγιστη πρόσληψη οξυγόνου (VCEmax), την ταχύτητα που συμβαίνει στη μέγιστη πρόσληψη οξυγόνου (vVC^max), το αναπνευστικό αναερόβιο κατώφλι (AT), τη δρομική οικονομία (RE) καθώς και το χρόνο διατήρησης στη vV02max (Tlimit)]. Μέθοδος: Στην έρευνα πήραν μέρος 11 μέτρια προπονημένοι (V02max=51-63±7.14 ml/kgr/min) φοιτητές φυσικής αγωγής (ηλικία: 19±0.85yr ύψος: 177.3±4.4cm, βάρος: 67.4±6.7kgr και σωματικό λίπος: 10.53±3.2%). Οι φοιτητές αφού χωρίστηκαν σε δυο ομάδες εκτέλεσαν για 4 εβδομάδες ένα εβδομαδιαίο προπονητικό πρόγραμμα το οποίο περιλάμβανε για την ομάδα A (n=6) δυο διαλειμματικές προπονήσεις μικρού χρόνου (30sec) στη vV02max και μία προπόνηση συνεχόμενου τρεξίματος στο 70% της vV02max και για την ομάδα Β (η=5) δύο διαλειμματικές προπονήσεις μεσαίου χρόνου που αντιστοιχούσαν στο 1/2 του ατομικού Tlimit (2.5-4min) στη vV02max καθώς και μία προπόνηση συνεχόμενου τρεξίματος 30min στο 70% της vV02max· Αποτελέσματα: Τόσο η ομάδα Α όσο και η ομάδα Β παρουσίασαν σημαντική αύξηση της VC^max (11.1% και 17.8% αντίστοιχα) και της vVC^max (4.9% και 11.4% αντίστοιχα) (ρ<0.05). Αύξηση παρατηρήθηκε στο AT της ομάδας Α (5.53% στο ποσοστό του AT σε σχέση με τη VChmax και 4.8% της νΑΤ) και της ομάδας Β (6.53% και 10% για τις αντίστοιχες παραμέτρους) (ρ<0.05). Η RE της ομάδας Α δεν παρουσίασε σημαντική βελτίωση (5.7%) (ρ>0.05) ενώ η RE της ομάδας Β παρέμεινε η ίδια. Τέλος η μεταβολή του Tlimit (+15%) στην ομάδα Α δεν ήταν σημαντική ενώ στη Β (-17%) ήταν σημαντική (ρ<0.05). Συμπέρασμα:Οι δύο διαλειμματικές προπονήσεις φαίνεται ότι είναι σχεδόν το ίδιο αποτελεσματικές ως προς τη βελτίωση των καρδιαναπνευστικών δεικτών αντοχής VCEmax, vVC^max, AT, RE και Tlimit.
A recipe for orbital eccentricity damping in the type-I regime for low viscosity 2D-discs

description: It is known that gap opening depends on the disc's viscosity; however, eccentricity damping formulas have only been derived at high viscosities, ignoring partial gap opening. We aim at obtaining a simple formula to model $e$-damping of the type-I regime in low viscosity discs, where even small planets may start opening partial. We perform high resolution 2D locally isothermal hydrodynamical simulations of planets with varying masses on fixed orbits in discs with varying aspect ratios and viscosities. We determine the torque and power felt by the planet to derive migration and eccentricity damping timescales. We first find a lower limit to the gap depths below which vortices appear; this happens roughly at the transition between type-I and type-II regimes. For the simulations that remain stable, we obtain a fit to the observed gap depth in the limit of vanishing eccentricities that is similar to the one currently used in the literature but is accurate down to $α=3.16\times 10^{-5}$. We record the $e$-damping efficiency as a function of the observed gap depth and $e$: when the planet has opened a deep enough gap, a linear trend is observed independently of $e$; at shallower gaps this linear trend is preserved at low $e$, while it deviates to more efficient damping when $e$ is comparable to the disc's scale height. Both trends can be understood on theoretical grounds and are reproduced by a simple fitting formula. Our combined fits yield a simple recipe to implement type-I $e$-damping in $N$-body for partial gap opening planets that is consistent with high-resolution 2D hydro-simulations. The typical error of the fit is of the order of a few percent, and lower than the error of type-I torque formulas widely used in the literature. This will allow a more self-consistent treatment of planet-disc interactions of the type-I regime for population synthesis models at low viscosities.
