description: A connected graph $G$ with at least $2m + 2n + 2$ vertices which contains a perfect matching is $E(m, n)$-{\it extendable}, if for any two sets of disjoint independent edges $M$ and $N$ with $|M| = m$ and $|N|= n$, there is a perfect matching $F$ in $G$ such that $M\subseteq F$ and $N\cap F=\emptyset$. Similarly, a connected graph with at least $n+2k+2$ vertices is called $(n,k)$-{\it extendable} if for any vertex set $S$ of size $n$ and any matching $M$ of size $k$ of $G-S$, $G-S-V(M)$ contains a perfect matching. Let $\varepsilon$ be a small positive constant, $b(G)$ and $t(G)$ be the binding number and toughness of a graph $G$. The two main theorems of this paper are: for every graph $G$ with sufficiently large order, 1) if $b(G)\geq 4/3+\varepsilon$, then $G$ is $E(m,n)$-extendable and also $(n,k)$-extendable; 2) if $t(G)\geq 1+\varepsilon$ and $G$ has a high connectivity, then $G$ is $E(m,n)$-extendable and also $(n,k)$-extendable. It is worth to point out that the binding number and toughness conditions for the existence of the general matching extension properties are almost same as that for the existence of perfect matchings.

title: Согласованная фильтрация биспектрально-организованных сигналов

Publisher: name: Издательство Радиотехника
Year: 2020

description: Постановка проблемы. Согласованная фильтрация сигнала широко применяется в разных сферах радиотехники – от связи и радиолокации до биомедицинских технологий. Если известен интервал интегрирования, то есть время прихода сигнала и его длительность, то обеспечивается максимизация отношения мощности сигнал/помеха на выходе согласованного фильтра. В противном случае характеристики фильтра ухудшаются. Биспектрально-организованные сигналы инвариантны к временной задержке и при биспектральной обработке позволяют избежать не только указанного недостатка, но и влияние многолучевого распространения сигнала. Кроме того, нечувствительность биспектра к помехам с симметричными распределениями позволяют получить дополнительный выигрыш в отношении мощности сигнал/помеха. Однако в настоящее время отсутствует универсальный подход к обработке биспектрально-организованных сигналов вне зависимости от вида модуляции и типа помех.

Цель. Синтезировать оптимальный фильтр для биспектрально-организованных сигналов и на его основе разработать приемник, работающий в условиях многолучевого распространения сигнала на фоне помех с симметричным распределением.

Результаты. Разработан оптимальный приемник, осуществляющий согласованную фильтрацию сигнала по критерию максимизации отношения абсолютных значений моментов третьего порядка сигнала и помехи, который на фоне помех с симметричными распределениями превосходит по вероятности ошибки приема символа оптимальный некогерентный прием по критерию максимума отношения правдоподобия. Показаны преимущества применения оптимальной обработки биспектрально-организованных сигналов перед некогерентным приемом гармонического сигнала.

Практическая значимость. Полученная математическая модель оптимального приема по критерию максимума отношения абсолютных моментов третьего порядка сигнала и помехи может быть использована для разработки приемных устройств, функционирующих в условиях многолучевого распространения сигналов на фоне различных помех.

description: We present results from a large mosaic of Suzaku observations of the Coma Cluster, the nearest and X-ray brightest hot, dynamically active, non-cool core system, focusing on the thermodynamic properties of the ICM on large scales. For azimuths not aligned with an infalling subcluster towards the southwest, our measured temperature and X-ray brightness profiles exhibit broadly consistent radial trends, with the temperature decreasing from about 8.5 keV at the cluster center to about 2 keV at a radius of 2 Mpc, which is the edge of our detection limit. The SW merger significantly boosts the surface brightness, allowing us to detect X-ray emission out to ~2.2 Mpc along this direction. Apart from the southwestern infalling subcluster, the surface brightness profiles show multiple edges around radii of 30-40 arcmin. The azimuthally averaged temperature profile, as well as the deprojected density and pressure profiles, all show a sharp drop consistent with an outward propagating shock front located at 40 arcmin, corresponding to the outermost edge of the giant radio halo observed at 352 MHz with the WSRT. The shock front may be powering this radio emission. A clear entropy excess inside of r_500 reflects the violent merging events linked with these morphological features. Beyond r_500, the entropy profiles of the Coma Cluster along the relatively relaxed directions are consistent with the power-law behavior expected from simple models of gravitational large-scale structure formation. The pressure is also in agreement at these radii with the expected values measured from SZ data from the Planck satellite. However, due to the large uncertainties associated with the Coma Cluster measurements, we cannot yet exclude an entropy flattening in this system consistent with that seen in more relaxed cool core clusters.

description: Постановка проблемы. Экспериментальные исследования состояния и динамики ионосферы над областями развития экстремальных метеорологических событий демонстрируют формирование различного рода эффектов. Во время масштабных метеорологических событий на средних широтах в спокойных гелиогеофизических условиях, когда воздействие на ионосферу сверху минимально, отмечается изменение параметров нейтральной атмосферы и ионосферы на 20% и более. Развитие физических представлений о наблюдаемых явлениях будет способствовать решению фундаментальных задач физики атмосферы, а также решению широкого ряда прикладных задач, к числу которых относятся задачи обеспечения надежного функционирования систем радиосвязи в любых природных или техногенных условиях.

Цель. Провести анализ параметров атмосферы и ионосферы в условиях метеорологического шторма в октябре 2018 г. в Калининградском регионе.

Результаты. В работе представлены результаты атмосферных и ионосферных наблюдений, проводившихся 22−25 октября 2018 г., в период, когда отсутствовали геомагнитные возмущения. Анализ позволяет заключить, что возмущения ионосферы 23−24 октября обусловлены влиянием метеорологических факторов и, в частности, усилением процессов генерации акустико-гравитационных волн (АГВ) в нижней атмосфере. Наиболее вероятной причиной отрицательных возмущений ионосферы являются процессы, связанные с диссипацией АГВ, распространяющихся из области метеорологического шторма, и усилением турбулентности в нижней термосфере.

Практическая значимость. Опыт эксплуатации различных систем связи и спутниковых систем навигации выявил их чувствительность к различным типам возмущений состояния атмосферы и ионосферы, которые могут приводить к существенному снижению показателя точности решения задачи навигации и позиционирования, сбоям в работе систем связи и т.д. Все это определяет актуальность и практическую значимость исследования влияния метеорологических возмущений на верхнюю атмосферу Земли.

description: Nanomachines have unique characteristics when compared to the counterpart macroscopic machines for biomedical applications. In studying nanomachines, how to generate locomotions is essential. One of the most potent approaches for powering nanomachines is the utilization of chemical reactions. In this study, we fabricate four types of platinum-based nanomotors. The one-dimensional nanomachine features one side of solid platinum, and the other side of solid gold, porous gold, solid gold-silver alloy, or porous gold-silver alloy. The electrokinetic mechanism of platinum-based nanomotors comes from the catalytic reaction between platinum and hydrogen peroxide (H₂O₂) solution. In this work, we study the enhancement of the chemical reactions for propulsion by structural modification of nanomotors. Two effects are exploited: the alloying effect that contributes to the change in chemical potential, and the surface effect that offers a greater area for reaction. By comparing the performances of different nanomotors, we confirm that both effects could enhance the performance of chemically driven nanowires. In particular, the alloying effect can bring more significant improvement. This research could assist the further development of efficiency chemical driven motors by materials and structural design.

description: It has been predicted theoretically and demonstrated experimentally that a planar slab supporting surface plasmons or surface phonon polaritons can behave as a super lens. However, the resolution is limited by the losses of the slab. In this letter, we point out that the resolution limit imposed by losses can be overcome by using time-dependent illumination.

description: We study the algorithmic thresholds for principal component analysis of Gaussian $k$-tensors with a planted rank-one spike, via Langevin dynamics and gradient descent. In order to efficiently recover the spike from natural initializations, the signal to noise ratio must diverge in the dimension. Our proof shows that the mechanism for the success/failure of recovery is the strength of the "curvature" of the spike on the maximum entropy region of the initial data. To demonstrate this, we study the dynamics on a generalized family of high-dimensional landscapes with planted signals, containing the spiked tensor models as specific instances. We identify thresholds of signal-to-noise ratios above which order 1 time recovery succeeds; in the case of the spiked tensor model these match the thresholds conjectured for algorithms such as Approximate Message Passing. Below these thresholds, where the curvature of the signal on the maximal entropy region is weak, we show that recovery from certain natural initializations takes at least stretched exponential time. Our approach combines global regularity estimates for spin glasses with point-wise estimates, to study the recovery problem by a perturbative approach.

description: We investigate theoretically under which conditions a stable and high-fidelity preparation of the biexciton state in a quantum dot can be realized by means of adiabatic rapid passage in the presence of acoustic phonon coupling. Our analysis is based on a numerically complete real-time path integral approach and comprises different schemes of optical driving using frequency-swept (chirped) pulses. We show that depending on the size of the biexciton binding energy, resonant two-photon excitations or two-color schemes can be favorable. It is demonstrated that the carrier-phonon interaction strongly affects the efficiency of the protocols and that a robust preparation of the biexciton is restricted to positive chirps and low temperatures. A considerable increase of the biexciton yield can be achieved realizing temperatures below 4 K.

description: We investigate the factors that influence the usefulness of supersonic collisions of Bose-Einstein condensates as a potential source of entangled atomic pairs by analyzing the reduction of the number difference fluctuations between regions of opposite momenta. We show that non-monochromaticity of the mother clouds is typically the leading limitation on number squeezing, and that the squeezing becomes less robust to this effect as the density of pairs grows. We develop a simple model that explains the relationship between density correlations and the number squeezing, allows one to estimate the squeezing from properties of the correlation peaks, and shows how the multi-mode nature of the scattering must be taken into account to understand the behavior of the pairing. We analyze the impact of the Bose enhancement on the number squeezing, by introducing a simplified low-gain model. We conclude that as far as squeezing is concerned the preferable configuration occurs when atoms are scattered not uniformly but rather into two well separated regions.

description: Contrariamente ao que se possa pensar, o termo Übermensch não é um neologismo nietzscheano. Como observa Walter Kaufmann, é possível encontrar esta palavra já no livro Geistliche Erquickungsstunden (1664) do teólogo Heinrich Müller (Kaufmann 1974: 307s.). Posteriormente, o termo aparece também em Herder, Jean Paul e Goethe (em particular, na primeira parte do Faust, no v. 490) (Goethe 1986: 16). O escritor grego Luciano de Samósata, acrescenta Kaufmann, havia já utilizado o termo hyperanthropos na sua obra Cataplus (Kaufmann 1974: 307; Babich 2012). Nietzsche, que se tinha formado como filólogo clásico, conhecia muito bem este autor e até possuia a colecção das suas obras completas. (Campioni el al. 2002: 373-381) No entanto, há poucas dúvidas de que foi Nietzsche quem tornou o termo Übermensch num dos conceitos filosóficos mais importantes do século XIX, conceito que exerceu uma grande influência na cultura e até na política do século XX.

description: This paper studies trace-based equivalences for systems combining nondeterministic and probabilistic choices. We show how trace semantics for such processes can be recovered by instantiating a coalgebraic construction known as the generalised powerset construction. We characterise and compare the resulting semantics to known definitions of trace equivalences appearing in the literature. Most of our results are based on the exciting interplay between monads and their presentations via algebraic theories.

description: Trafitec har for Vejdirektoratet udviklet state-of-the-art metoder til systematisk opgørelse af bilisters oplevede serviceniveau i kryds. Resultater af sådanne opgørelser beskriver, hvor tilfreds bilister er i signalregulerede og prioriterede kryds (Jensen, 2020). Til at beskrive hvordan trafikafvikling, krydsdesign, manøvre og andre forhold påvirker bilisters tilfredshed, har 80 tilfældigt udvalgte respondenter set 42 videoklip fra 30 signalregulerede og 28 videoklip fra 20 prioriterede kryds. Videoklippene er udført i HD-format med kameradækning ud af forrude, ved sidespejle/sideruder og ud af bagrude samt et GPS-baseret speedometer. Respondenter har vurderet videoklip på en tilfredshedsskala med 6 trin gående fra meget tilfreds til meget utilfreds. I alt er der indsamlet 2.800 tilfredshedsvurderinger af de 70 videoklip. Der er anvendt en pålidelig, valideret metode, hvor respondenter ser videoklip på 23-148 sekunder optaget fra en kørende personbil, der kører gennem krydsene ved enten at svinge til venstre, køre ligeud eller svinge til højre. Hvert videoklip og kryds er beskrevet med ca. 600 variable, der angiver trafikafvikling, krydsudformning, manøvre, vejr osv. Der er opstillet to typer modeller, der beskriver sammenhænge mellem bilisters tilfredshed og forholdene i kryds. Både kumulative logit modeller og generaliserede lineære modeller indeholder kun statistisk signifikante variable, der påvirker bilisters tilfredshed på logisk facon. Det er hovedsageligt ventetiden, der påvirker bilisters tilfredshed i signalregulerede og prioriterede kryds. Derudover påvirkes tilfredsheden af krydstype, manøvre, type af vige-/stoppligt eller type af signal, og desuden indgår synergieffekter mellem de signifikante variable. En kumulativ logit model returnerer den procentuelle fordeling af bilister på de 6 tilfredshedskategorier og dette oversættes efterfølgende til oplevet serviceniveau

description: We introduce a new approach to studying spherical spin glass dynamics based on differential inequalities for one-time observables. Using this approach, we obtain an approximate phase diagram for the evolution of the energy $H$ and its gradient under Langevin dynamics for spherical $p$-spin models. We then derive several consequences of this phase diagram. For example, at any temperature, uniformly over all starting points, the process must reach and remain in an absorbing region of large negative values of $H$ and large (in norm) gradients in order 1 time. Furthermore, if the process starts in a neighborhood of a critical point of $H$ with negative energy, then both the gradient and energy must increase macroscopically under this evolution, even if this critical point is a saddle with index of order $N$. As a key technical tool, we estimate Sobolev norms of spin glass Hamiltonians, which are of independent interest.

description: Fra 2000 til 2019 gikk antall drepte eller hardt skadde i trafikken i Norge ned med mer enn 50 %. Antall drepte gikk ned med nesten 70 %. Mange faktorer har bidratt til nedgangen. De tre viktigste er tiltak på vegnettet, sikrere biler og lavere fart. Økt bruk av bilbelter, økt bruk av automatisk trafikkontroll og økt bruk av sykkelhjelm har også bidratt. Nedgangen i antall drepte eller hardt skadde fra 2000 til 2019, beregnet med en trendlinje, var på 800 personer (fra 1479 til 679). Til sammen kan de faktorer det er mulig å beregne virkninger av, forklare 59 % av denne nedgangen. Det vil si at antall drepte eller hardt skadde i 2019 ville ha vært 1149 (i stedet for 679) dersom disse faktorene ikke hadde bidratt. Det har ikke lykkes å forklare hele nedgangen i antall drepte eller hardt skadde. Andre faktorer enn dem denne studien har identifisert, må derfor også ha bidratt til den gunstige utviklingen. Det kan ikke utelukkes at rapporteringen av hardt skadde i trafikken er redusert i den perioden studien omfatter.

description: Null Energy Condition (NEC) can be violated in a consistent way in models with unconventional kinetic terms, notably, in Galileon theories and their generalizations. We make use of one of these, the scale-invariant kinetic braiding model, to discuss whether a universe can in principle be created by man-made processes. We find that even though the simplest models of this sort can have both healthy Minkowski vacuum and consistent NEC-violating phase, there is an obstruction for creating a universe in a straightforward fashion. To get around this obstruction, we design a more complicated model, and present a scenario for the creation of a universe in the laboratory.

description: The LINC project aims to study interactions between passengers and autonomous vehicles in natural settings at the campus of Technical University of Denmark. To leverage the potential of IoT components in smartphone-based surveying, a system to identify specific spatial, temporal and occupancy contexts relevant for passengers’ experience was proposed as a central data collection strategy in the LINC project. Based on predefined contextual triggers specific questionnaires can be distributed to affected passengers. This work focuses on the data-based discrimination between two fundamental contexts for LINC passengers: be-in and be-out (BIBO) of the vehicle. We present empirical evidence that Bluetooth-low-energy beacons (BLE) have the potential for BIBO independent classification. We compare BLE with other smartphone onboard sensors, such as the global positioning system (GPS) and the accelerometer through: (i) random-forest (RF); (ii) multi-layer perceptron (MLP); and (iii) smartphone native off-the-shelve classifiers. We also perform a sensitivity analysis regarding the impact that faulty BIBO ground-truth has on the performance of the supervised classifiers (i) and (ii). Results show that BLE and GPS could allow reciprocal validation for BIBO passengers’ status. This potential might lift passengers from providing any further validation. We describe the smartphone-sensing platform deployed to gather the dataset used in this work, which involves passengers and autonomous vehicles in a realistic setting.

description: Recently, Fici, Restivo, Silva, and Zamboni introduced the notion of a $k$-anti-power, which is defined as a word of the form $w^{(1)} w^{(2)} \cdots w^{(k)}$, where $w^{(1)}, w^{(2)}, \ldots, w^{(k)}$ are distinct words of the same length. For an infinite word $w$ and a positive integer $k$, define $AP_j(w,k)$ to be the set of all integers $m$ such that $w_{j+1} w_{j+2} \cdots w_{j+km}$ is a $k$-anti-power, where $w_i$ denotes the $i$-th letter of $w$. Define also $\mathcal{F}_j(k) = (2 \mathbb{Z}^+ - 1) \cap AP_j(\mathbf{t},k)$, where $\mathbf{t}$ denotes the Thue-Morse word. For all $k \in \mathbb{Z}^+$, $γ_j(k) = \min (AP_j(\mathbf{t},k))$ is a well-defined positive integer, and for $k \in \mathbb{Z}^+$ sufficiently large, $Γ_j(k) = \sup ((2 \mathbb{Z}^+ -1) \setminus \mathcal{F}_j(k))$ is a well-defined odd positive integer. In his 2018 paper, Defant shows that $γ_0(k)$ and $Γ_0(k)$ grow linearly in $k$. We generalize Defant's methods to prove that $γ_j(k)$ and $Γ_j(k)$ grow linearly in $k$ for any nonnegative integer $j$. In particular, we show that $\displaystyle 1/10 \leq \liminf_{k \rightarrow \infty} (γ_j(k)/k) \leq 9/10$ and $\displaystyle 1/5 \leq \limsup_{k \rightarrow \infty} (γ_j(k)/k) \leq 3/2$. Additionally, we show that $\displaystyle \liminf_{k \rightarrow \infty} (Γ_j(k)/k) = 3/2$ and $\displaystyle \limsup_{k \rightarrow \infty} (Γ_j(k)/k) = 3$.

description: A soberania, junto com a democracia, a representação e a constituição, forma como que o esqueleto conceptual da filosofia política, social e jurídica moderna. A sua linha-mestra pressupõe a existência em acto de um poder político que governa sem superior (supremo) num dado território, assim como uma presença independente de Estados geográfica- e normativamente separados resultantes sobretudo da chamada Paz de Vestefália de 1648. Enquanto ideia sustentadora da política e do direito na modernidade, soberania é tradicionalmente sinónima de “absolutidade”, isto é, de um poder político incondicionado e ilimitado, ou de “fundamento”, isto é, de razão última que justifica a existência de um poder político em concreto.

description: Aims. Our aim is to search for and study the origin of the low-amplitude and long-periodic radial velocity (RV) variations in K giants. Methods. We present high-resolution RV measurements of K2 giant epsilon CrB from February 2005 to January 2012 using the fiber-fed Bohyunsan Observatory Echelle Spectrograph (BOES) at the Bohyunsan Optical Astronomy Observatory (BOAO). Results. We find that the RV measurements for epsilon CrB exhibit a periodic variation of 417.9 +/- 0.5 days with a semi-amplitude of 129.4 +/- 2.0 m/s. There is no correlation between RV measurements and chromospheric activity in the Ca II H region, the Hipparcos photometry, or bisector velocity span. Conclusions. Keplerian motion is the most likely explanation, with the RV variations arising from an orbital motion. Assuming a possible stellar mass of 1.7 +/- 0.1 M_Sun for epsilon CrB, we obtain a minimum mass for the planetary companion of 6.7 +/- 0.3 M_Jup with an orbital semi-major axis of 1.3 AU and eccentricity of 0.11. We also discuss the implications of our observations for stellar metallicity versus planet occurrence rate and stellar mass versus planetary mass relations.

Landau Level Mixing and the Fractional Quantum Hall Effect

description: We derive effective Hamiltonians for the fractional quantum Hall effect in n=0 and n=1 Landau levels that account perturbatively for Landau level mixing by electron-electron interactions. To second order in the ratio of electron-electron interaction to cyclotron energy, Landau level mixing is accounted for by constructing effective interaction Hamiltonians that include two-body and three-body contributions characterized by Haldane pseudopotentials. Our study builds upon previous treatments, using as a stepping stone the observation that the effective Hamiltonian is fully determined by the few-body problem with N=2 and N=3 electrons in the partially filled Landau level. For the n=0 case we use a first quantization approach to provide a compact and transparent derivation of the effective Hamiltonian which captures a class of virtual processes omitted in earlier derivations of Landau-level-mixing corrected Haldane pseudopotentials.

description: We introduce a generalized notion of inference system to support more flexible interpretations of recursive definitions. Besides axioms and inference rules with the usual meaning, we allow also coaxioms, which are, intuitively, axioms which can only be applied "at infinite depth" in a proof tree. Coaxioms allow us to interpret recursive definitions as fixed points which are not necessarily the least, nor the greatest one, whose existence is guaranteed by a smooth extension of classical results. This notion nicely subsumes standard inference systems and their inductive and coinductive interpretation, thus allowing formal reasoning in cases where the inductive and coinductive interpretation do not provide the intended meaning, but are rather mixed together.

description: It is well known that for any integers $k$ and $g$, there is a graph with chromatic number at least $k$ and girth at least $g$. In 1960's, Erdős and Hajnal conjectured that for any $k$ and $g$, there exists a number $h(k,g)$, such that every graph with chromatic number at least $h(k,g)$ contains a subgraph with chromatic number at least $k$ and girth at least $g$. In 1977, Rödl proved the case for $g=4$ and arbitrary $k$. We prove the fractional chromatic number version of Rödl's result.

description: Offentlig transport er en kritisk service i København, fordi mange beboere ikke ejer en bil, og under mange omstændigheder er bilkørsel ikke praktisk i byens centrum på grund af smalle veje og manglende parkering. Som svar på COVID-19 har de danske sundhedsmyndigheder fastlagt en minimumspolitik for social afstand på 1 meter i det offentlige rum. Følgende undersøgelse simulerer passagerernes flow på tre repræsentative stationer i den københavnske metro for at afgøre, om disse afstandskrav kan overholdes, samt om eventuelle fysiske ændringer bør foretages. Undersøgelsen udføres med en mikrosimulering i Bentley Legion af passagerstrømmen på tre stationer med små, mellemstore og store trafikstrømme. Simuleringen er agentbaseret, og den individuelle objektive funktion er minimering af omkostninger i henhold til gåafstand, komfort og frustration. Resultaterne viser, at for de fleste stationer, er den fysiske infrastruktur og den forventede trafikstrøm forenelige med målene for social afstand. For nogle få af de mest efterspurgte stationer, især dem, der fungerer som intermodale knudepunkter, er der imidlertid store vanskeligheder med at opnå de ønskede sociale afstandsforanstaltninger. Især den intermodale hubstation, Nørreport, har ikke korridorer og rulletrapper, der fordeles korrekt i henhold til fodgængerstrømmen. Denne station er under jorden, og det er desværre ikke let at ændre i infrastrukturen for dette knudepunkt.

description: We consider the non-condensate density and density fluctuations of a trapped dipolar Bose-Einstein condensate, focusing on the regime where a roton-like excitation spectrum develops. Our results show that a characteristic peak in the non-condensate density occurs at trap center due to the rotons. In this regime we also find that the anomalous density becomes positive and peaked, giving rise to enhanced density fluctuations. We calculate the non-condensate density in momentum space and show that a small momentum halo is associated with the roton excitations.
