description: In SETI, when searching for "beacons" -- transmissions intended for us and meant to get our attention -- one must guess the appropriate frequency to search by considering what frequencies would be universally obvious to other species. This is a well known concept in game theory, where such solutions to a non-communicative cooperative game (such as a mutual search) are called "Schelling points." It is noteworthy, therefore, that when developing his eponymous units, Planck called them "natural" because they "remain meaningful for all times and also for extraterrestrial and non-human cultures." Here, I apply Planck's suggestion in the context of Schelling points in SETI with a "Planck Frequency Comb," constructed by multiplying the Planck energy by integer powers of the fine structure constant. This comb includes a small number of frequencies in regions of the electromagnetic spectrum where laser and radio SETI typically operates. Searches might proceed and individual teeth in the comb, or at many teeth at once, across the electromagnetic spectrum. Indeed, the latter strategy can be additionally justified by the transmitter's desire to signal at many frequencies at once, to improve the chances that the receiver will guess one of them correctly. There are many arbitrary and anthropocentric choices in this comb's construction, and indeed one can construct several different frequency combs with only minor and arbitrary modifications. This suggests that it may be fruitful to search for signals arriving in frequency combs of arbitrary spacing. And even though the frequencies suggested here are only debatably "better" than others proposed, the addition of the Planck Frequency Comb to the list of "magic frequencies" can only help searches for extraterrestrial beacons.

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We consider the problem of consumption of stars by a supermassive black hole (SBH) at the center of an axisymmetric galaxy. Inside the SBH sphere of influence, motion of stars in the mean field is regular and can be described analytically in terms of three integrals of motion: the energy E, the z-component of angular momentum L_z, and the secular Hamiltonian H. There exist two classes of orbits, tubes and saucers; saucers occupy the low-angular-momentum parts of phase space and their fraction is proportional to the degree of flattening of the nucleus. Perturbations due to gravitational encounters lead to diffusion of stars in integral space, which can be described using the Fokker-Planck equation. We calculate the diffusion coefficients and solve this equation in the two-dimensional phase space (L_z, H), for various values of the capture radius and the degree of flattening. Capture rates are found to be modestly higher than in the spherical case, up to a factor of a few, and most captures take place from saucer orbits. We also carry out a set of collisional N-body simulations to confirm the predictions of the Fokker-Planck models. We discuss the implications of our results for rates of tidal disruption and capture in the Milky Way and external galaxies.

description: We consider measurement-based quantum computation (MBQC) on thermal states of the interacting cluster Hamiltonian containing interactions between the cluster stabilizers that undergoes thermal phase transitions. We show that the long-range order of the symmetry breaking thermal states below a critical temperature drastically enhance the robustness of MBQC against thermal excitations. Specifically, we show the enhancement in two-dimensional cases and prove that MBQC is topologically protected below the critical temperature in three-dimensional cases. The interacting cluster Hamiltonian allows us to perform MBQC even at a temperature an order of magnitude higher than that of the free cluster Hamiltonian.

description: Effective ΔS=1 four fermion operators involving left- and right-handed currents are relevant in left-right gauge extensions of the standard model and scalar extension of the Yukawa sector. They induce K to ππ decays which are strictly constrained by experimental data, typically resulting in strong bounds on the new physics scales or parameters. We evaluate the K to ππ hadronic matrix elements of such operators within the phenomenological framework of the Chiral Quark Model. The results are consistent with the estimates used in a previous work on TeV scale left-right symmetry, thus confirming the conclusions obtained there.

description: Let CABA be the category of complete and atomic boolean algebras and complete boolean homomorphisms, and let CSL be the category of complete meet-semilattices and complete meet-homomorphisms. We show that the forgetful functor from CABA to CSL has a left adjoint. This allows us to describe an endofunctor H on CABA such that the category Alg(H) of algebras for H is dually equivalent to the category Coalg(P) of coalgebras for the powerset endofunctor P on Set. As a consequence, we derive Thomason duality from Tarski duality, thus paralleling how Jónsson-Tarski duality is derived from Stone duality.

description: We discuss some aspects of the Horava-Lifshitz cosmology with different matter components considered as dominants at different stages of the cosmic evolution (each stage is represented by an equation of state pressure/density=constant). We compare cosmological solutions from this theory with their counterparts of General Relativity (Friedmann cosmology). At early times, the Horava- Lifshitz cosmology contains a curvature-dependent dominant term which is stiff matter-reminiscent and this fact motivates to discuss, in some detail, this term beside the usual stiff matter component (pressure=density) if we are thinking in the role that this fluid could have played early in the framework of the holographic cosmology. Nevertheless, we show that an early stiff matter component is of little relevance in Horava-Lifshitz cosmology.

description: For two metric spaces $\mathbb X$ and $\mathcal Y$, the chromatic number $χ(\mathbb X;\mathcal Y)$ of $\mathbb X$ with forbidden $\mathcal Y$ is the smallest $k$ such that there is a coloring of the points of $\mathbb X$ with $k$ colors and no monochromatic copy of $\mathcal Y$. In this paper, we show that for each finite metric space $\mathcal{M}$ that contains at least two points the value $χ\left(\mathbb R^n_\infty; \mathcal M \right)$ grows exponentially with $n$. We also provide explicit lower and upper bounds for some special $\mathcal M$.

description: Alles Süßwasser auf der Erde ist irgendwann als Niederschlag auf die Kontinente gefallen um dann entweder oberflächlich über Flüsse und Seen oder unterirdisch als Grundwasser wieder in Richtung Ozean zu fließen. Die Aufenthaltszeit von Wasser auf den verschiedenen Pfaden ist eine sehr wichtige Größe für die Hydrologie allgemein, aber auch für das Studium einzelner Teile der Hydrosphäre wie Seen und Grundwasserleiter. Wie lange ist Wasser im Untergrund unterwegs, bevor es an einer Quelle zutage tritt oder aus einem Brunnen gepumpt wird? Könnten Schadstoffe der modernen Zeit demnach bald zur Quelle vordringen? Wird das Grundwasserreservoir in überblickbaren Zeiten erneuert oder ist es „fossil“ und damit ebenso endlich wie Erdöl? Wie rasch wird das Tiefenwasser in einem See erneuert und mit frischem Sauerstoff versorgt? Verändert sich die Zirkulationsdynamik des Atlantiks, und somit das Klima in Europa? Solche Fragen treiben Umweltforscher um, wenn sie Datierungsmethoden für Wasser entwickeln und anwenden.

description: In verified generic programming, one cannot exploit the structure of concrete data types but has to rely on well chosen sets of specifications or abstract data types (ADTs). Functors and monads are at the core of many applications of functional programming. This raises the question of what useful ADTs for verified functors and monads could look like. The functorial map of many important monads preserves extensional equality. For instance, if $f, g : A \rightarrow B$ are extensionally equal, that is, $\forall x \in A, \ f \ x = g \ x$, then $map \ f : List \ A \rightarrow List \ B$ and $map \ g$ are also extensionally equal. This suggests that preservation of extensional equality could be a useful principle in verified generic programming. We explore this possibility with a minimalist approach: we deal with (the lack of) extensional equality in Martin-Löf's intensional type theories without extending the theories or using full-fledged setoids. Perhaps surprisingly, this minimal approach turns out to be extremely useful. It allows one to derive simple generic proofs of monadic laws but also verified, generic results in dynamical systems and control theory. In turn, these results avoid tedious code duplication and ad-hoc proofs. Thus, our work is a contribution towards pragmatic, verified generic programming.

description: We apply neutron diffraction, high-resolution synchrotron x-ray diffraction, magnetization measurements, electronic structure calculations, and quantum Monte-Carlo simulations to unravel the structure and magnetism of (CuCl)LaTa2O7. Despite the pseudo-tetragonal crystallographic unit cell, this compound features an orthorhombic superstructure, similar to the Nb-containing (CuX)LaNb2O7 with X = Cl and Br. The spin lattice entails dimers formed by the antiferromagnetic fourth-neighbor coupling J4, as well as a large number of nonequivalent interdimer couplings quantified by an effective exchange parameter Jeff. In (CuCl)LaTa2O7, the interdimer couplings are sufficiently strong to induce the long-range magnetic order with the Neel temperature TN~7 K and the ordered magnetic moment of 0.53 mu_B, as measured with neutron diffraction. This magnetic behavior can be accounted for by Jeff/J4~1.6 and J4~16 K. We further propose a general magnetic phase diagram for the (CuCl)LaNb2O7-type compounds, and explain the transition from the gapped spin-singlet (dimer) ground state in (CuCl)LaNb2O7 to the long-range antiferromagnetic order in (CuCl)LaTa2O7 and (CuBr)LaNb2O7 by an increase in the magnitude of the interdimer couplings Jeff/J_4, with the (CuCl)LaM2O7 (M = Nb, Ta) compounds lying on different sides of the quantum critical point that separates the singlet and long-range-ordered magnetic ground states.

description: Постановка проблемы. Рассматривается область фазового пространства с нечеткими границами, в которой динамика управляемой системы задана TS-моделью типа MISO с базой правил с точностью до функций каждого из заключений продукционных правил. В отличие от известных решений, в работе предлагается в каждом из заключений продукционных правил в качестве функций использовать управления, синтезированные на основе условия максимума функции обобщенной мощности. В таком случае обеспечение различных режимов функционирования требует построения соответствующего множества гиперповерхностей переключения, вид которых определяется синтезирующей функцией.

Цель. Разработать метод синтеза интеллектуальных управлений на основе анализа поведения динамических мер на гиперповерхности переключения в области фазового пространства с нечеткими границами.

Результаты. Синтезировано новое нечеткое управление на основе разработанного метода.

Практическая значимость. Проведенное математическое моделирование показало, что синтезированное нечеткое управление в сравнении с построенными на основе условия максимума функции обобщенной мощности кусочно-постоянным и кусочно-непрерывным управлениями обеспечивает выигрыш по времени переходного процесса и затратам на управление.

description: Постановка проблемы. Возрастающее значение анализа журнальных файлов в больших компьютерных системах требует разработки автоматизированных методов обработки неструктурированных данных, позволяющих извлекать соответствующую информацию из журнальных файлов большого объема без необходимости вмешательства человека. Анализ неструктурированных данных системных журналов показывает, что аномальные события в компьютерных системах могут быть представлены группами обусловленными различными причинами их возникновения. В результате задача идентификации типов аномальных состояний компьютерных систем сводится не к бинарной, а мультиклассовой классификации и может быть решена методами машинного обучения.

Учитывая, что количество аномальных событий, как правило, невелико, для обучения алгоритмов машинного обучения целесообразно использовать как «аномальные», так и «нормальные» события. В результате процесс классификации типа аномалии сводится к двухэтапной схеме. На первом этапе решается задача бинарной классификации, в результате которой формируются два класса: 1 – «аномалия» или 0 – «нормальное событие», а на втором этапе оценивается конкретный тип аномалии.

Цель. Исследовать эффективность алгоритмов машинного обучения при мультиклассовой классификации аномальных (аварийных) состояний крупных компьютерных систем путем автоматизированной обработки неструктурированных данных системных журналов.

Результаты. Оценка эффективности мультиклассовой двухэтапной схемы классификации с использованием перекрёстной проверки показала, что наилучшими показателями обладают алгоритмы Logistic Regression и Random Forest, которые также оказались наиболее эффективными для задачи бинарной классификации при обнаружении аномальных состояний. Установлено, что подобные классификаторы хуже работают при определении смешанных событий.

Практическая значимость. Для повышения эффективности двухэтапной процедуры предложено использовать дополнительный «логирующий компонент», содержащий дополнительную информацию: время события, имя потока, программный компонент, который сгенерировал сообщение и так далее. Показано, что использование подобного дополнительного атрибута позволяет улучшить качественные показатели классификации в среднем до 10%. Наибольший рост эффективности наблюдается для алгоритмов k-nearest neighbors и Logistic Regression.

Modelling of solar and stellar brightness variations
Creators: name: Nemec, Nina-Elisabeth
Publisher: name: Zenodo
Year: 2023

description: The emergence of magnetic field on stellar surfaces leads to the formation of magnetic features, such as dark spots and bright faculae. The expected facular and spot signals in stellar data are quite different, as they have distinct temporal and spectral profiles. The plethora of photometric data obtained by past and current space missions, plus the high precision transmission spectroscopy data brought by the James Webb Space Telescope have underlined the needs for a better understanding and modelling of stellar brightness variations on various timescales. Here we present various modelling efforts that have allowed to understand solar brightness variations in the broader context of stellar variability. To model the magnetic component of the variability we follow the SATIRE approach of calculating brightness variations, which was shown to reproduce the solar variability in great detail. We connect variability of the Total Solar Irradiance (i.e. the spectral integrated solar flux) to that measured in various spectral passbands, routinely used in broad-band photometry (e.g., CoRoT, Kepler, TESS. etc). Recent simulations with the 3D MHD radiative code MURaM made it also possible to calculate variability of spectral solar irradiance
 brought by the granulation which dominates total variability on timescales below about a day. By combining calculations of spectral solar irradiance variability brought by magnetic features and granulation we obtain a model capable of returning variability on timescales from minutes to decades. Currently, massive efforts are put into extending these calculations to stars with various values of metallicity and effective temperature.

description: A bramble in an undirected graph $G$ is a family of connected subgraphs of $G$ such that for every two subgraphs $H_1$ and $H_2$ in the bramble either $V(H_1) \cap V(H_2) \neq \emptyset$ or there is an edge of $G$ with one endpoint in $V(H_1)$ and the second endpoint in $V(H_2)$. The order of the bramble is the minimum size of a vertex set that intersects all elements of a bramble. Brambles are objects dual to treewidth: As shown by Seymour and Thomas, the maximum order of a bramble in an undirected graph $G$ equals one plus the treewidth of $G$. However, as shown by Grohe and Marx, brambles of high order may necessarily be of exponential size: In a constant-degree $n$-vertex expander a bramble of order $Ω(n^{1/2+δ})$ requires size exponential in $Ω(n^{2δ})$ for any fixed $δ\in (0,\frac{1}{2}]$. On the other hand, the combination of results of Grohe and Marx and Chekuri and Chuzhoy shows that a graph of treewidth $k$ admits a bramble of order $\widetildeΩ(k^{1/2})$ and size $\widetilde{\mathcal{O}}(k^{3/2})$. ($\widetildeΩ$ and $\widetilde{\mathcal{O}}$ hide polylogarithmic factors and divisors, respectively.) In this note, we first sharpen the second bound by proving that every graph $G$ of treewidth at least $k$ contains a bramble of order $\widetildeΩ(k^{1/2})$ and congestion $2$, i.e., every vertex of $G$ is contained in at most two elements of the bramble (thus the bramble is of size linear in its order). Second, we provide a tight upper bound for the lower bound of Grohe and Marx: For every $δ\in (0,\frac{1}{2}]$, every graph $G$ of treewidth at least $k$ contains a bramble of order $\widetildeΩ(k^{1/2+δ})$ and size $2^{\widetilde{\mathcal{O}}(k^{2δ})}$.

On the Taylor expansion of $λ$-terms and the groupoid structure of their rigid approximants

description: We show that the normal form of the Taylor expansion of a $λ$-term is isomorphic to its Böhm tree, improving Ehrhard and Regnier's original proof along three independent directions. First, we simplify the final step of the proof by following the left reduction strategy directly in the resource calculus, avoiding to introduce an abstract machine ad hoc. We also introduce a groupoid of permutations of copies of arguments in a rigid variant of the resource calculus, and relate the coefficients of Taylor expansion with this structure, while Ehrhard and Regnier worked with groups of permutations of occurrences of variables. Finally, we extend all the results to a nondeterministic setting: by contrast with previous attempts, we show that the uniformity property that was crucial in Ehrhard and Regnier's approach can be preserved in this setting.

description: High-temperature cuprate superconductors have been known to exhibit significant pressure effects. In order to fathom the origin of why and how Tc is affected by pressure, we have recently studied the pressure effects on Tc adoptig a model that contains two cupper d-orbitals derived from first-principles band calculations, where the dz2 orbital is considere on top of the usually considered dx2-y2 orbital. In that paper, we have identified two origins for the Tc enhancement under hydrostatic pressure: (i) while at ambient pressure the smaller the hybridization of other orbital components the higher the Tc, an application of pressure acts to reduce the multiorbital mxing on the Fermi surface, which we call the orbital distillation effects, and (ii) the increase of the band width with pressure also contributes to the enhancement. In the present paper, we further elabolrate the two points. As for point (i), while the reduction of the apical oxygen height under pressure tends to increase the dz2 mixture, hence to lower Tc, here we show that this effect is strongly reduced in bi-layer materials due to the pyramidal coordination of oxygen atoms. As for point (ii), we show that the enhancement of Tc due to the increase in the band width is caused by the effect that the many-body renormalization arising from the self-energy is reduced.

On the correctness of monadic backward induction

description: In control theory, to solve a finite-horizon sequential decision problem (SDP) commonly means to find a list of decision rules that result in an optimal expected total reward (or cost) when taking a given number of decision steps. SDPs are routinely solved using Bellman's backward induction. Textbook authors (e.g. Bertsekas or Puterman) typically give more or less formal proofs to show that the backward induction algorithm is correct as solution method for deterministic and stochastic SDPs. Botta, Jansson and Ionescu propose a generic framework for finite horizon, monadic SDPs together with a monadic version of backward induction for solving such SDPs. In monadic SDPs, the monad captures a generic notion of uncertainty, while a generic measure function aggregates rewards. In the present paper we define a notion of correctness for monadic SDPs and identify three conditions that allow us to prove a correctness result for monadic backward induction that is comparable to textbook correctness proofs for ordinary backward induction. The conditions that we impose are fairly general and can be cast in category-theoretical terms using the notion of Eilenberg-Moore-algebra. They hold in familiar settings like those of deterministic or stochastic SDPs but we also give examples in which they fail. Our results show that backward induction can safely be employed for a broader class of SDPs than usually treated in textbooks. However, they also rule out certain instances that were considered admissible in the context of Botta et al.'s generic framework. Our development is formalised in Idris as an extension of the Botta et al. framework and the sources are available as supplementary material.

description: Elliptic partial differential equations (PDEs) with discontinuous diffusion coefficients occur in application domains such as diffusions through porous media, electro-magnetic field propagation on heterogeneous media, and diffusion processes on rough surfaces. The standard approach to numerically treating such problems using finite element methods is to assume that the discontinuities lie on the boundaries of the cells in the initial triangulation. However, this does not match applications where discontinuities occur on curves, surfaces, or manifolds, and could even be unknown beforehand. One of the obstacles to treating such discontinuity problems is that the usual perturbation theory for elliptic PDEs assumes bounds for the distortion of the coefficients in the $L_\infty$ norm and this in turn requires that the discontinuities are matched exactly when the coefficients are approximated. We present a new approach based on distortion of the coefficients in an $L_q$ norm with $q

L’art-thérapie. Traumas et réparation du sujet dans le discours de Gaël Faye

Publisher: name: Stichproben - Wiener Zeitschrift für kritische Afrikastudien / Vienna Journal of African Studies
Year: 2022

description: La musique et la littérature entretiennent une relation ancienne qui, à l’époque contemporaine, se fait de plus en plus étroite. Ces deux arts peuvent servir de catharsis pour réguler les traumatismes du sujet privé ou collectif et, de ce fait, jouer une fonction thérapeutique et réparatrice. L’expérience de l’écriture et de la pratique musicale permet ainsi une transformation et une libération de la mémoire du sujet. Ainsi quelques productions contemporaines, particulièrement de la diaspora africaine, essaient de répondre aux grands traumas de l’existence à travers des mises en musique et en récits personnels des blessures historiques, comme par exemple le génocide perpétré contre les Tutsis du Rwanda raconté par des artistes écrivains d’origine rwandaise comme Gaël Faye. L’approche homéostatique de la littérature et de la musique populaire débouche sur une visée éthique et eudémonique. Il s’agira de voir comment la littérature et la musique s’enchevêtrent pour construire un statut discursif auctorial particulier et de quelle manière la production artistique impacte l’ethos de son auteur affecté par le trauma.
Role Of Generalized Cosmic Chaplygin Gas In Accelerating Universe : A Field Theoretical Prescription

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this paper we investigate the role played by dark energy in the form of Generalized cosmic Chaplygin gas in an accelerating universe described by FRW cosmology. We have tried to describe the model from the theoretical point of view of a field, by introducing a scalar field $ϕ$ and a self interacting potential $V(ϕ)$. The corresponding expressions for the field are obtained for the given model. Statefinder parameters have been used to characterize the dark energy model. Plots have been generated for characterizing different phases of universe diagrammatically and a comparative study is performed with the Modified Chaplygin gas model. As an outcome of the study, Generalized cosmic Chaplygin gas is identified as a much less constrained form of dark energy as compared to modified Chaplygin gas.

description: The charge carrier dynamics of organic solar cells are strongly influenced by trapping and allow to draw conclusions on the loss mechanisms limiting the photovoltaic performance. In this study we derive the recombination order Δ of mobile charge carriers. For annealed P3HT:PCBM solar cells, it allows us to pinpoint the dominant recombination of mobile with trapped charge carriers in tail states. While the characteristic tail state energy of about 40 meV rises to about 100 meV for 30 h oxygen exposure under illumination, Δ decreases only weakly from 1.70 to 1.62: This corresponds to a slight shift towards trap-assisted recombination.
