description: We consider how fractional excitations bound to a dislocation evolve as the dislocation is separated into a pair of disclinations. We show that some dislocation-bound excitations (such as Majorana modes and half-quantum vortices) are possible only if the elementary dislocation consists of two inequivalent disclinations, as is the case for stripes or square lattices but not for triangular lattices. The existence of multiple inequivalent disclination classes governs the two-dimensional melting of quantum liquid crystals (i.e., nematics and hexatics), determining whether superfluidity and orientational order can simultaneously vanish at a continuous transition.

description: Industry 4.0 is driven by Cyber-Physical Systems and Smart Products. Smart Products provide a value to both its users and its manufacturers in terms of a closer connection to the customer and his data as well as the provided smart services. However, many companies, especially SMEs, struggle with the transformation of their existing product portfolio into smart products. In order to facilitate this process, this paper presents a set of smart product use-cases from a manufacturer’s perspective. These use-cases can guide the definition of a smart product and be used during its architecture development and realization. Initially the paper gives an introduction in the field of smart products. After that the research results, based on case-study research, are presented. This includes the methodological approach, the case-study data collection and analysis. Finally, a set of use-cases, their definitions and components are presented and highlighted from the perspective of a smart product manufacturer.

description: This paper aims to evince the corrections on the black string warped horizon in the braneworld paradigm, and their drastic physical consequences, as well as to provide subsequent applications in astrophysics. Our analysis concerning black holes on the brane departs from the Schwarzschild case, where the black string is unstable to large-scale perturbation. The cognizable measurability of the black string horizon corrections due to braneworld effects is investigated, as well as their applications in the variation of quasars luminosity. We delve into the case wherein two solutions of Einstein's equations proposed by Casadio, Fabbri, and Mazzacurati, regarding black hole metrics presenting a post-Newtonian parameter measured on the brane. In this scenario, it is possible to analyze purely the braneworld corrected variation in quasars luminosity, by an appropriate choice of the post-Newtonian parameter that precludes Hawking radiation on the brane: the variation in quasars luminosity is uniquely provided by pure braneworld effects, as the Hawking radiation on the brane is suppressed.

description: High order FIR filters employ model reduction techniques, in order to decrease power consumption and time delay. During reduction high order FIR filters are converted into low order IIR filters preserving stability and phase linearity as main features. Matlab simulations of an audio system with these reduced filters are presented. Furthermore, the influence of order on power consumption is discussed. © 2005 Copernicus GmbH.
Equivalent teleparallel theories in diagonalizable spacetimes: Comment on "Metric-affine approach to teleparallel gravity"
Creators: name: Formiga, J. B.
Publisher: name: arXiv
Year: 2013
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: It is well known that the teleparallel equivalent of general relativity yields the same vacuum solutions as general relativity does, which ensures that this particular teleparallel model is in good agreement with experiments. A less known result concerns the existence of a wider class of teleparallel models which also admits these solutions when the spacetime is diagonalizable by means of a coordinate change. However, it is stated in Ref. [Phys. Rev. D 67, 044016 (2003).] that the teleparallel equivalent of general relativity is the only teleparallel model which admits black holes. To show that this statement is not true, I prove the existence of this wider class by taking an approach different from that of Ref. [Phys. Rev. D 19, 3524 (1979)].

description: For future communication systems, filter bank multicarrier schemes offer the flexibility to increase spectrum utilization in heterogeneous wireless environments by good separation of signals in the frequency domain. To fully exploit this property for frame detection and synchronization, the advantage of the filter bank should be taken at the receiver side. In this work, the concept of frequency domain processing for frame detection and synchronization is analyzed and a suitable preamble design as well as corresponding estimation algorithms is discussed. The theoretical performance of the detection and estimation schemes is derived and compared with simulation-based assessments. The results show that, even though the frequency domain algorithms are sensitive to carrier frequency offsets, satisfactory frame detection and synchronization can be achieved in the frequency domain. In comparison to time domain synchronization methods, the computational complexity increases; however, enhanced robustness in shared spectrum access scenarios is gained in case the described frequency domain approach is utilized.

description: Recently, blockchain-based tokens have earned an important role in fields such as the art market or online gaming. First approaches exist, which adopt the potentials of blockchain tokens in supply chain management to increase transparency, visibility, automation, and disintermediation of supply chains. In context, the tokenization of assets in supply chains refers to the practice of creating virtual representations of physical assets on the blockchain. Solutions in supply chain management based on the tokenization of assets vary in terms of application objectives, token types, asset characteristics, as well as the complexities of supply chain events to be mapped on the blockchain. Currently, however, no review exists that summarizes the characteristics of blockchain-based tokens and their scope of applications. This paper provides a clear terminological distinction of existing blockchain token types and therefore distinguishes between fungible tokens, non-fungible tokens, smart non-fungible tokens, and dynamic smart non-fungible tokens. Subsequently, the token types are classified regarding their traceability, modifiability, and authorization to evaluate suitability for mapping assets in supply chains. Given the potential of blockchain in supply chain management, the results of the review serve as a foundation for a practical guide supporting the selection process of suitable token types for industrial applications.
Hofer geometry and cotangent fibers

description: For a class of Riemannian manifolds that include products of arbitrary compact manifolds with manifolds of nonpositive sectional curvature on the one hand, or with certain positive-curvature examples such as spheres of dimension at least 3 and compact semisimple Lie groups on the other, we show that the Hamiltonian diffeomorphism group of the cotangent bundle contains as subgroups infinite-dimensional normed vector spaces that are bi-Lipschitz embedded with respect to Hofer's metric; moreover these subgroups can be taken to consist of diffeomorphisms supported in an arbitrary neighborhood of the zero section. In fact, the orbit of a fiber of the cotangent bundle with respect to any of these subgroups is quasi-isometrically embedded with respect to the induced Hofer metric on the orbit of the fiber under the whole group. The diffeomorphisms in these subgroups are obtained from reparametrizations of the geodesic flow. Our proofs involve a study of the Hamiltonian-perturbed Floer complex of a pair of cotangent fibers (or, more generally, of a conormal bundle together with a cotangent fiber). Although the homology of this complex vanishes, an analysis of its boundary depth yields the lower bounds on the Lagrangian Hofer metric required for our main results.

description: GALA is a freely distributed Fortran code to derive automatically the atmospheric parameters (temperature, gravity, microturbulent velocity and overall metallicity) and abundances for individual species of stellar spectra using the classical method based on the equivalent widths of metallic lines. The abundances of individual spectral lines are derived by using the WIDTH9 code developed by R. L. Kurucz. GALA is designed to obtain the best model atmosphere, by optimizing temperature, surface gravity, microturbulent velocity and metallicity, after rejecting the discrepant lines. Finally, it computes accurate internal errors for each atmospheric parameter and abundance. The code permits to obtain chemical abundances and atmospheric parameters for large stellar samples in a very short time, thus making GALA an useful tool in the epoch of the multi-object spectrographs and large surveys. An extensive set of tests with both synthetic and observed spectra is performed and discussed to explore the capabilities and robustness of the code.

description: Постановка проблемы. В локационных системах, особенно в ближней локации, случайные сигналы и помехи имеют большой динамический диапазон амплитудных, частотных и временных характеристик и нестационарный характер. Информативные параметры сигналов часто являются нецентрированными случайными величинами, для которых априорно неизвестны математические ожидания. Получение оценок математических ожиданий по одной реализации часто затруднено из-за нестационарности сигналов и ограниченного объема выборки, а также высокого быстродействия систем. Из-за отсутствия сведений о математических ожиданиях нецентрированных случайных параметров часто нет возможности применить известные корреляционные методы обработки сигналов.
Цель. Обосновать регрессионный алгоритм обнаружения и распознавания сигналов по относительной ширине энергетического спектра, инвариантный к средней частоте энергетического спектра сигнала и его дисперсии, использующий в качестве информативных параметров интервалы между нулями входных реализаций, а в качестве априорной информации – их коэффициенты начальной регрессии.
Результаты. Обоснованы рабочие характеристики инвариантного к средней частоте и дисперсии сигналов регрессионного алгоритма, использующего в качестве информативного параметра интервалы между нулями входных реализаций, а в качестве априорной информации их коэффициенты начальной регрессии, отличающиеся для сигналов и помех.
Практическая значимость. Полученные результаты могут быть использованы в радиолокационных системах ближней
локации при обработке сигналов на частоте Доплера для повышения их помехоустойчивости при работе в условиях активных и пассивных помех, а также в информационных системах в каналах помех.

This diagram includes interlayer singlet phase observed in fluoride K$_3$Cu$_2$F$_7$ and exotic entangled spin-orbital phases. For a monolayer case, realized in K$_2$CuF$_4$, we perform similar calculations in finite temperature and show that the alternating-orbital ferromagnet decays first to an entangled uniform ferromagnet and then to a paramagnetic phase.

description: In 2001, seventeen professionals set up the manifesto for agile software development. They wanted to define values and basic principles for better software development. On top of being brought into focus, the manifesto has been widely adopted by developers, in software-developing organizations and outside the world of IT. Agile principles and their implementation in practice have paved the way for radical new and innovative ways of software and product development. In parallel, the understanding of the manifesto’s underlying principles evolved over time. This, in turn, may affect current and future applications of agile principles. This article presents results from a survey and an interview study in collaboration with the original contributors of the manifesto for agile software development. Furthermore, it comprises the results from a workshop with one of the original authors. This publication focuses on the origins of the manifesto, the contributors’ views from today’s perspective, and their outlook on future directions. We evaluated 11 responses from the survey and 14 interviews to understand the viewpoint of the contributors. They emphasize that agile methods need to be carefully selected and agile should not be seen as a silver bullet. They underline the importance of considering the variety of different practices and methods that had an influence on the manifesto. Furthermore, they mention that people should question their current understanding of “agile” and recommend reconsidering the core ideas of the manifesto.
Temperature effects on the surface plasmon resonance in copper nanoparticles

description: The temperature dependences of the energy and the width of a surface plasmon resonance are studied for copper nanoparticles 17 - 59 nm in size in the silica host matrix in the temperature interval 293 - 460 K. An increase of the temperature leads to the red shift and the broadening of the surface plasmon resonance in Cu nanoparticles. The obtained dependences are analyzed within the framework of a theoretical model considering the thermal expansion of a nanoparticle, the electron-phonon scattering in a nanoparticle, and the temperature dependence of the dielectric permittivity of the host matrix. The thermal expansion is shown to be the main mechanism responsible for the temperature-induced red shift of the surface plasmon resonance in copper nanoparticles. The thermal volume expansion coefficient for Cu nanoparticles is found to be size-independent in the studied size range. Meanwhile, the increase of the electron-phonon scattering rate with the temperature is shown to be the dominant mechanism of the surface plasmon resonance broadening in copper nanoparticles.

description: Постановка проблемы. В настоящее время оценка эффективной площади рассеяния воздушной цели является одной из ключевых и до конца нерешенных задач в радиолокации. Процесс получения радиолокационной информации о воздушной цели при проведении натурных и физических экспериментов является весьма затруднительным, поскольку связан со значительными материальными и временными затратами. В качестве наиболее доступного способа получения информации о
характеристиках обратного вторичного излучения воздушной цели предлагается использовать математическое моделирование.
Цель. Провести анализ существующих алгоритмов проверки видимости треугольных фацетов и выбрать оптимальный алгоритм по критерию максимального быстродействия и высокой достоверности.
Результаты. Проведен анализ наиболее часто применяемых в радиолокации алгоритмов проверки видимости треугольников (фацетов) при оценке эффективной площади рассеяния фацетных моделей воздушных целей. Полученные результаты оценки временных затрат на количественном и качественном уровнях показывают невозможность применения существующих алгоритмов в реальном масштабе времени, а также низкую в некоторых случаях достоверность результатов. Предлагаемое сокращение размера массива координат вершин фацетов осуществляется переходом к точечной модели поверхности воздушной цели, при этом в качестве точек рассматриваются центры масс фацетов. Для проверки видимости трехмерных точечных моделей воздушных целей предложено использовать алгоритм Hidden Point Removal, впервые применяемый для решения задач оценки эффективной площади рассеяния.
Практическая значимость. Применение комбинации алгоритмов Hidden Point Removal и проверки видимых фацетов по
углу между векторами нормалей и направления облучения позволяет повысить достоверность результатов проверки видимости фацетов при оценке эффективной площади рассеяния моделей воздушных целей в реальном масштабе времени.

description: Artifacts from the Laurel Hill Plantation site in southern Dorchester County, South Carolina, suggest an early 19th -century Settlement Indian occupation. These indigenous groups were forced to adapt and utilize new strategies to cope with the onslaught of European colonization. They found themselves betwixt and between political economies marred by enslavement and changing cultural and geographic realities, obscuring traditional practices. We explore these connections through a native-produced low-fired earthenware assemblage, a decorated pearlware collection, and a late 17th to early 18th -century glass bead sample, possibly representing multi-generational, passed-down heirloom objects serving as visual cues of remembrance.

description: Постановка проблемы. Технология энергоассистируемой магнитной записи, в основе которой лежит кратковременное уменьшение коэрцитивной силы записывающей среды ниже поля записи за счет локального нагрева (термоассистированная магнитная запись) или прецессии вектора намагниченности под действием микроволнового излучения (микроволновая асси-стированная запись), предполагает возможность значительного уменьшения среднего термостабильного размера зерна и увеличения поверхностной плотности магнитной записи существенно выше 1 Тб/дюйм2.
Цель. Провести анализ основных параметров магнитных сред и магнитных головок чтения-записи для энергоассистируемой магнитной записи, используемым материалам, а также альтернативным магнитным материалам и концепциям сред записи.
Результаты. Проанализированы основные параметры магнитных сред и магнитных головок термоассистируемой и микро-волновой ассистируемой записи, используемые магнитные материалы, а также альтернативные материалы и концепции сред энергоассистируемой магнитной записи.
Практическая значимость. Рассмотренные технологии позволяют увеличить поверхностную плотность записи до 5 Тб/дюйм2 на основе энергоассистируемой записи, а при использовании комбинации HAMR или MAMR и (бит)структу¬рированных технологий – до 10 Тб/дюйм2 и выше.

description: For cavity-assisted optomechanical cooling experiments, in order to achieve the quantum ground state of the mechanical oscillator, the cavity bandwidth needs to be smaller than the mechanical frequency. In the literature, this is the so-called resolved-sideband or good-cavity limit, and this is based on an understanding of optomechanical dynamics. We provide a different but physically equivalent explanation of such a limit: that is, information loss due to finite cavity bandwidth. With an optimal feedback control to recover the information in the cavity output, we can surpass the resolved-sideband limit and achieve the quantum ground state. In addition, recovering this information can also significantly enhance the entanglement between the cavity mode and the mechanical oscillator. Especially when the environmental temperature is high, such optomechanical entanglement will either exist or vanish critically depending on whether information is recovered or not. This provides a vivid example of a quantum eraser in the optomechanical system.

description: In a multitude of applications like e.g. in automotive radar systems a localization of multiple passive targets in the observed area is necessary. This contribution presents a robust approach based on trilateration to detect point scatterers in a two-dimensional plane using the reflection and transmission information of only two antennas. The proposed algorithm can identify and remove ambiguities in target detection which unavoidably occur in certain target constellations in such a two-antenna configuration.

description: Постановка проблемы. Работа посвящена формулировке и решению самосогласованной задачи расчета эффективной массы, g-фактора и спектра электрона в идеальных квантовых нитях, то есть полупроводниковых 1D-гетероструктурах, спектр поперечного движения которых содержит единственный связанный уровень. Для расчета спектра электрона необходима его продольная и поперечная эффективная масса. В свою очередь, сами эти массы критически зависят от радиуса нити и энергии основного состояния. Это обуславливает самосогласованный характер рассматриваемой задачи. Для ее решения теория Кейна, описывающая формирование эффективной массы и g-фактора электрона в объемных полупроводниках состава АIIIВIV, обобщена на рассматриваемый случай с «недостроенной» зонной структурой поперечных уровней. Основная идея такого обобщения состоит в том, что роль запрещенной зоны играет энергетическая щель между потолком валентной зоны и основным состоянием электрона в потенциальной яме.
Цель. Решить самосогласованную задачу расчета эффективной массы и g-фактора электрона в совокупности с его спектром в тонкой квантовой нити.
Результаты. Рассмотрены зонные гетероструктуры только ковариантного типа. Это позволило избежать связывания дырок с последующим образованием экситона со своим сложным спектром. Показано, что энергия (единственного) поперечного уровня начинает ощутимо расти только с некоторого критического радиуса нити, а до этого – экспоненциально подавлена. Установлено, что g-фактор электрона, как и в квантовых точках, всегда является разностью двух величин, одна из которых относится собственно к материалу нити, а другая – к материалу барьера. Причем первая, в отличие от второй, в широких пределах управляется внешними полями, что создает базу для различных технических приложений.
Практическая значимость. Эффективное значение g-фактора в нити всегда является разностью двух величин, одна из
которых относится к материалу нити, а другая – к материалу барьера. Для квантовых точек и квантовых ям ситуация совершенно аналогична, так как описанный механизм воздействия однородного магнитного поля на зонную структуру универсален.
