description: We analyze different possibilities to explain the wide initial spin period distribution of radio pulsars presented by Noutsos et al. (2013). With a population synthesis modeling we demonstrate that magnetic field decay can be used to interpret the difference between the recent results by Noutsos et al. (2013) and those by Popov & Turolla (2012), where a much younger population of NSs associated with supernova remnants with known ages has been studied. In particular, an exponential field decay with tau_mag = 5Myrs can produce a "tail" in the reconstructed initial spin period distribution (as obtained by Noutsos et al. 2013) up to P_0 > 1 s starting with a standard gaussian with P_0 = 0.3 s and sigma_P = 0.15 s. Another option to explain the difference between initial spin period distributions from Noutsos et al. (2013) and Popov & Turolla (2012) -- the emerging magnetic field -- is also briefly discussed.

NFTs and Copyright: The Evolution of Digital Copyright Protection?
Creators: name: Grant, Owen
Publisher: name: Zenodo
Year: 2022

description: Non-Fungible Tokens NFTs are digitally scarce, non-exchangeable cryptographic tokens that represent an underlying work such as a picture or video and exist on a blockchain, mostly used to trade in digital art and collectibles. They are the most recent blockchain development and offer a great deal of promise for the future in numerous sectors. Despite this they are unregulated and suffer from a bad reputation and illegitimacy that exists across current public blockchains and cryptocurrency, due to fraudulent actors and misconceptions of what is owned with an NFT. In this paper I posit that NFTs could be used to upgrade Digital Rights Management (DRM) through two possible solutions; a copyright register on a blockchain or moving DRM to blockchain – Distributed Digital Rights Management (DDRM). The objective of these solutions is to solve the ongoing problem of digital piracy, which DRM has never been successful in stopping through present-day encryption or content-blocking services. The other benefit is for authors to be guaranteed fair remuneration for their works by cutting out some unnecessary intermediaries and issuing licences through smart contracts. I consider that if successful, these solutions constitute an evolution of digital copyright protection, though they must first overcome legal, practical, and logistical problems. For either solution to be successful, smart contracts must be able to constitute valid legal contracts with binding obligations as all NFTs contain these to execute terms set by the person creating the token (minter). I show that under current Scots law and under England and Wales contract law smart contracts can satisfy formation requirements of a contract, but they still must overcome the challenges presented by blockchain and a lack of intermediaries such as an established dispute resolution mechanism. I demonstrate in this paper that current digital copyright protection could be upgraded with the use of NFTs, specifically in giving authors direct control over the following DRM functions for which previously they were beholden to intermediaries: Assignment; Licensing; Royalty payments; and Registration. Despite this I outline that each solution must overcome some significant challenges, leading me to conclude that a blockchain copyright register utilising NFTs is not likely to be attempted in the near future but could offer huge benefits for exploiters as well as authors. DDRM is a solution already being developed by RAIRtech and is by its nature an idea that numerous companies can compete to develop best. In the final analysis I conclude that despite their issues NFTs are the evolution of digital copyright protection. The bar has been set relatively low with current DRM, meaning an improvement would constitute an evolution, which is evidenced by the lack of reliable ownership information, authors’ options for revenue, and present-day piracy statistics.

description: The 4 sites and 8 sites 1D anti-ferromagnetic Heisenberg chains in the Jordan-Wigner representation are investigated within the standard Hartree-Fock and RPA approaches, both in the symmetry unbroken and in the symmetry broken phases. A translation invariant groundstate, obtained by the projection method as a linear combination of a symmetry-broken HF state and its image under reflection, is also considered, for each chain type. It is found that the projection method considerably improves the HF treatment for instance as far as the groundstate energy is concerned, but also with respect to the RPA energies. The results are furthermore confronted with the ones obtained within so-called SCRPA scheme.

description: An important element estimating a good seamless handover scheme is that how rapidly and accurately can anticipate the imminent Layer 3 handover. The Fast Handovers for Mobile IPv6 (FMIPv6) may be the best scheme for it because the anticipation is made by collaboration with Layer 2. The emerging IEEE802.21 standard defines Media Independent Handover Functions (MIHF) that assist mobile nodes to seamlessly roam across heterogeneous access networks. The aim of this paper is to present a mechanism which uses existing IEEE802.21 MIH services to optimize the FMIPv6 procedure and define new MIH primitives to support this procedure. In our proposed we let that each AR (Access Router) maintains a CoA (Care of Address) table and generates the new CoA from nAR then it passes this NCoA to the MN using IEEE802.21 MIH primitives before starting handover .So, The proposed scheme is depending on implementing DAD process in nAR instead of MN comparing with existing Fast Handover scheme. When NCoA arrives to MN, the binding updates to home agent and correspondent node will be performed before starting L2 handover .From the evaluation results, we can see that the proposed fast handover scheme can achieve low handover latency comparing with existing FMIPv6 scheme . In addition, with the proposed scheme, we can design the network cost- effectively by reducing coverage overlap between adjacent cells because the handover initiation time in the FMIPv6 is decreased.
Universal Longtime Dynamics in Dense Simple Fluids
Creators: name: Mazenko, Gene F.
Publisher: name: arXiv
Year: 2013
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: There appears to be a longtime, very slowly evolving state in dense simple fluids which, for high enough density, approaches a glassy nonergodic state. The nature of the nonergodic state can be characterized by the associated static equilibrium state. In particular, systems driven by Smoluchowski or Newtonian dynamics share the same static equilibrium and nonergodic states. That these systems share the same nonergodic states is a highly nontrivial statement and requires establishing a number of results. In the high-density regime one finds that an equilibrating system decays via a three-step process identified in mode-coupling theory (MCT). For densities greater than a critical density one has time-power-law decay with exponents a and b. There are sets of linear fluctuation dissipation relations (FDRs) which connect the cumulants of these two fields. The form of the FDRs is the same for both Smoluchowski or Newtonian dynamics. While we show this universality of nonergodic states within perturbation theory, we expect it to be true more generally. The nature of the approach to the nonergodic state has been suggested by MCT. It has been a point of contention that MCT is a phenomenological theory and not a systematic theory with prospects for improvement. Recently a systematic theory has been developed. It naturally allows one to calculate self-consistently density cumulants in a perturbation expansion in a pseudo-potential. At leading order one obtains a kinetic kernel quadratic in the density. This is a "one-loop" theory like MCT. At this one-loop level one finds vertex corrections which depend on the three-point equilibrium cumulants. Here we assume these vertex-corrections can be ignored and focus on the higher-order loops. We show that one can sum up all of the loop contributions. The higher-order loops do not change the nonergodic state parameters substantially.

The characterization of wettability of substrates by liquid nanodrops

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Wettability of a substrates is characterized by a contact angle. Applicability of the simple formula developed by Derjaguin, which relates to the contact angle and disjoining pressure to nano-scale liquid droplets is reconsidered within the framework of the theory of the first-order wetting transition of volatile liquids. It is concluded that his formula is generally correct for large droplets on an incompletely-wettable substrate. But it can not be applied to nanodroplets, in particular, on a completely-wettable substrate. An effective contact angle can be defined even for the nanaodroplet. A formula similar to the Derjaguin formula is proposed by which we can calculate the contact angle of nanodorplets on both an incompletely- and a completely-wettable substrate for which the whole volume of the droplet is under the influence of the disjoining pressure.

description: In this article we review the relation between string theory and non-equilibrium physics based on our previously published work. First we explain why a theory of quantum gravity and non-equilibrium statistical physics should be related in the first place. Then we present the necessary background from the recent research in non-equilibrium physics. The review discusses the relationship of string theory and aging phenomena, as well as the connection between AdS/CFT correspondence and the Jarzynski identity. We also discuss the emergent symmetries in fully developed turbulence and the corresponding non-equilibrium stationary states. Finally we outline a larger picture regarding the relationship between non-perturbative quantum gravity and non-equilibrium statistical physics. This relationship can be understood as a natural generalization of the well-known Wilsonian relation between local quantum field theory and equilibrium statistical physics of critical phenomena. According to this picture the AdS/CFT duality is just an example of a more general connection between non-perturbative quantum gravity and non-equilibrium physics. In the appendix of this review we discuss a new kind of complementarity between thermodynamics and statistical physics which should be important in the context of black hole complementarity.

Theoretical methods for non-relativistic quantum and classical scattering processes

Subjects: Atomic, molecular and optical physics not elsewhere classified

description: This dissertation discusses the theoretical methods for quantum scattering in the context of x-ray scattering from electrons and classical scattering in the context of collisions between Rydberg atoms.
 A method for describing non-relativistic x-ray scattering from bound electrons is presented. The approach described incorporates the full spatial dependence of the incident x-ray field and is non-perturbative in the incident x-ray field. The x-ray scattering probability obtained by numerical solution for the case of free-electrons is bench-marked with well known analytical free-electron results.
 A recent investigation by Fuchs \emph{et al.} [Nat. Phys. 11, 964 (2015)] revealed an anomalous frequency shift of at least 800 eV in non-linear Compton scattering of high-intensity x-rays by electrons in solid beryllium. The x-ray scattering approach described is used to explore the role of binding energy, band structure, electron-electron correlation and a semi-Compton channel in the frequency shift of scattered x-rays for different scattered angles. The results of the calculation do not exhibit an additional redshift for the scattered x-rays beyond the non-linear Compton shift predicted by the free-electron model.
 The interference between Compton scattering and nonlinear Compton scattering from a two-color field in the x-ray regime is theoretically analyzed for bound electrons. A discussion of the underlying phase shifts and the dependence of the interference effect on the polarizations of the incident and outgoing fields are presented.
 The problem of using x-ray scattering to image the dynamics of an electron in a bound system is examined. Previous work on imaging electronic wave-packet dynamics with x-ray scattering revealed that the scattering patterns deviate substantially from the notion of instantaneous momentum density of the wave packet. Here we show that the scattering patterns can provide clear insights into the electronic wave packet dynamics if the final state of the scattered electron and the scattered photon momentum are determined simultaneously. The scattering probability is shown to be proportional to the modulus square of the Fourier transform of the instantaneous electronic spatial wave function weighted by the final state of the electron.
 Collisional ionization between Rydberg atoms is examined. The dependence of the ionization cross section on the magnitude and the direction of orbital angular momentum of the electrons and the direction of the Laplace-Runge-Lenz vector of the electrons is studied. The case of exchange ionization is examined and its dependence on the magnitude of angular momentum of the electrons is discussed.

A logarithmic-periodic antenna is coupled to a graphene flake that is produced by exfoliation on SiO2. The detector was characterized with the free-electron laser FELBE for wavelengths from 8 um to 220 um. The detector rise time is 50 ps in the wavelength range from 30 um to 220 um. Autocorrelation measurements exploiting the nonlinear photocurrent response at high intensities reveal an intrinsic response time below 10 ps. This detector has a high potential for characterizing temporal overlaps, e. g. in two-color pump-probe experiments.

description: Mesopelagic fishes are an important element of marine food webs, a huge, still mostly untapped food resource, and great contributors to the biological carbon pump, whose future under climate change scenarios is unknown. The shrinking of commercial fishes within decades has been an alarming observation, but its causes remain contended. Here, we investigate the effect of warming climate on mesopelagic fish size in the eastern Mediterranean Sea during a glacial-interglacial-glacial transition of the Middle Pleistocene (marine isotope stages 20–18; 814–712 Kyr B.P.), which included a 4ºC increase of global seawater temperature. Our results based on fossil otoliths show that the median size of lanternfishes, one of the most abundant groups of mesopelagic fishes in fossil and modern assemblages, declined by ~35% with climate warming at the community level. However, individual mesopelagic species showed different and often opposing trends in size across the studied time interval, suggesting that climate warming in the interglacial resulted in an ecological shift toward increased relative abundance of smaller-sized mesopelagic fishes due to geographic and/or bathymetric distribution range shifts, and the size-dependent effects of warming.

Bubble divergences and gauge symmetries in spin foams

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

description: Spin foams are candidate state-sum models for transition amplitudes in quantum gravity. An active research subject is to identify the possible divergences of spin foam models, or alternatively to show that models are finite. We will discuss in detail the (non--occurrence of) divergences in the Barrett-Crane model, formulated as an integral of delta function weights only. We will furthermore present a simple method to estimate the divergence degree of the so-called bubbles for general spin foam models. Divergences in spin foams are expected to be related to the existence of gauge symmetries (diffeomorphisms). Thus we have to conclude that such gauge symmetries are not (fully) present in the model we consider. But we will identify a class of gauge symmetries which occur at special solutions of the equations imposed by the delta function weights. This situation is surprisingly similar to the case of broken diffeomorphism symmetries in discrete gravity, which are present around flat solutions. We introduce a method to derive (Ward-identity-like) equations for the vertex amplitude of the model in the case of broken gauge symmetries.

description: In this paper, we propose a new routing protocol for heterogeneous Wireless Body Area Sensor Networks (WBASNs); Mobility-supporting Adaptive Threshold-based Thermal-aware Energy-efficientMulti-hop ProTocol (M-ATTEMPT). A prototype is defined for employing heterogeneous sensors on human body. Direct communication is used for real-time traffic (critical data) or on-demand data while Multi-hop communication is used for normal data delivery. One of the prime challenges in WBASNs is sensing of the heat generated by the implanted sensor nodes. The proposed routing algorithm is thermal-aware which senses the link Hot-spot and routes the data away from these links. Continuous mobility of human body causes disconnection between previous established links. So, mobility support and energy-management is introduced to overcome the problem. Linear Programming (LP) model for maximum information extraction and minimum energy consumption is presented in this study. MATLAB simulations of proposed routing algorithm are performed for lifetime and successful packet delivery in comparison with Multi-hop communication. The results show that the proposed routing algorithm has less energy consumption and more reliable as compared to Multi-hop communication.

The Recurrent Nova T CrB Did Not Erupt in 1842

description: The recurrent nova T CrB was one of the first well observed nova eruptions in 1866, and 80 years later it erupted again in 1946. Just after the 1866 eruption, Sir John Herschel reported to the Monthly Notices that he had seen the same star in his naked-eye charting of the sky on 1842 June 9, implying that there was a prior eruption 24 years earlier. Unfortunately, the chart in the Monthly Notices was ambiguous and misleading, so it has long been unclear whether T CrB did indeed have an eruption in 1842. To resolve this, I have searched the various archives with Herschel material, and have found his original correspondence. In one letter from 1866 to William Huggins, Herschel enclosed his own copy of his original observations, and with this all the ambiguities are resolved. It turns out that Herschel's indicated star was at the same position as a steady background star (BD+25°3020, V=7.06, G8V) and not that of T CrB, and Herschel regularly was seeing stars as faint as V=7.5 mag because he was using an opera glass. With this, there is no evidence for a T CrB eruption in 1842.

description: Orbital and spin ordering phenomena in strongly correlated systems are commonly studied using the local-density approximation + dynamical mean-field theory approach. Typically, however, such simulations are restricted to simplified models (density-density Coulomb interactions, high symmetry couplings and few-band models). In this work we implement an efficient general hybridization-expansion continuous-time quantum Monte Carlo impurity solver (Krylov approach) which allows us to investigate orbital and spin ordering in a more realistic setting, including interactions that are often neglected (e.g., spin-flip and pair-hopping terms), enlarged basis sets (full d versus eg), low-symmetry distortions, and reaching the very low-temperature (experimental) regime. We use this solver to study ordering phenomena in a selection of exemplary low-symmetry transition-metal oxides: LaMnO3 and rare-earth manganites as well as the perovskites CaVO3 and YTiO3. We show that spin-flip and pair hopping terms do not affect the Kugel-Khomskii orbital-order melting transition in rare-earth manganites, or the suppression of orbital fluctuations driven by crystal field and Coulomb repulsion. For the Mott insulator YTiO3 we find a ferromagnetic transition temperature 50 K, in remarkably good agreement with experiments. For LaMnO3 we show that the classical t2g-spin approximation, commonly adopted for studying manganites, yields indeed an occupied eg orbital in very good agreement with that obtained for the full d 5-orbital Hubbard model, while the spin-spin e_g-t_{2g} correlation function calculated from the full d model is 0.74, very close to the value expected for aligned eg and t2g spins; the eg spectral function matrix is also well reproduced. Finally, we show that the t2g screening reduces the eg-eg Coulomb repulsion by about 10%

description: High PAPR is one of the major challenges in using OFDM for communication, resulting in using inefficient linear amplifiers at the transmitter, or distortion if nonlinear amplifiers are used. Means of reducing PAPR in OFDM waveforms have been extensively researched, but those methods still have some need to avoid distortion. Using a pair of complementary sequences, an OFDM signal can be created that is constant in envelope, reducing the PAPR to unity and allowing the use of nonlinear amplifiers. Sequence pairs restricted to a particular alphabet are information-inefficient so instead a means of encoding onto a pair of complementary sequences is developed such that the length of the sequence increases linearly with the number of information symbols. The structure of this constant-modulus OFDM signal can also be used at the receiver to deal with channel fading and improve performance in noise. All of these concepts are extended to two-dimensional complementary sequence pairs for use in MIMO or broadcast applications using a uniform linear array while maintaining constant modulus on all antennas. This extension also includes exploration of additional structure imposed by the method of construction in multiple dimensions.

description: The concept of the broadband epsilon-near-zero meta-atom consisting of layered stacks with specified metallic filling ratio and thickness is proposed based on the Bergman spectral representation of the effective permittivity. The step-like metal-dielectric multilayer structures are designed to achieve realistic broadband epsilon-near-zero meta-atoms in optical frequency range. These meta-atoms can be integrated as building blocks for unconventional optical components with exotic electromagnetic properties over a wide frequency range, such as the demonstrated broadband directional emission and phase front shaping.

Co monolayers and adatoms on Pd(100), Pd(111) and Pd(110): Anisotropy of magnetic properties

description: We investigate to what extent the magnetic properties of deposited nanostructures can be influenced by selecting as a support different surfaces of the same substrate material. Fully relativistic ab initio calculations were performed for Co monolayers and adatoms on Pd(100), Pd(111), and Pd(110) surfaces. Changing the crystallographic orientation of the surface has a moderate effect on the spin magnetic moment and on the number of holes in the d band, a larger effect on the orbital magnetic moment but sometimes a dramatic effect on the magnetocrystalline anisotropy energy (MAE) and on the magnetic dipole term T_alpha. The dependence of T_alpha on the magnetization direction alpha can lead to a strong apparent anisotropy of the spin magnetic moment as deduced from the X-ray magnetic circular dichroism (XMCD) sum rules. For systems in which the spin-orbit coupling is not very strong, the T_alpha term can be understood as arising from the differences between components of the spin magnetic moment associated with different magnetic quantum numbers m.

Creators: name: Blarzino, Andrea

description: Años ardientes y míticos propone un recorrido historiográfico que abarca más de medio siglo (1908-1963) de publicaciones italianas sobre la poesía española de la Edad de Plata (1902-1939). Hasta 1937 se trata de raras traducciones y reseñas que encuentran exiguos espacios en algunas revistas literarias. El año 1938 marca el punto de inflexión entre estas aisladas incursiones hispanófilas y el nacimiento del hispanismo “militante”, bajo el impulso de Carlo Bo y Oreste Macrí. La versión de Bo del “Llanto” lorquiano revela un territorio literario aún todo por explorar que los dos estudiosos eligen también como lugar de investigación meta-crítica en torno a la Poesía, “objeto” que abordan con herramientas y criterios “diferentemente” herméticos. El último capítulo examina las seis antologías de poetas españoles del siglo XX publicadas en Italia hasta 1963, analizando tanto la gestación del canon “italiano” de los poetas españoles de la época como el carácter específico de cada una de ellas, en pos de lo que el propio Macrí, hablando del “libro Antología”, define como “un género literario autónomo y original dentro de la categoría de la poesía”, es decir, como un ulterior e ineludible objeto de estudio.

description: We present a microfabricated surface-electrode ion trap with a pair of integrated waveguides that generate a standing microwave field resonant with the 171Yb+ hyperfine qubit. The waveguides are engineered to position the wave antinode near the center of the trap, resulting in maximum field amplitude and uniformity along the trap axis. By calibrating the relative amplitudes and phases of the waveguide currents, we can control the polarization of the microwave field to reduce off-resonant coupling to undesired Zeeman sublevels. We demonstrate single-qubit pi-rotations as fast as 1 us with less than 6 % variation in Rabi frequency over an 800 um microwave interaction region. Fully compensating pulse sequences further improve the uniformity of X-gates across this interaction region.

description: Out of equilibrium quantum systems, on top of quantum fluctuations, display complex temporal patterns. Such time fluctuations are generically exponentially small in the system volume and can be therefore safely ignored in most of the cases. However, if one consider small quench experiments, time fluctuations can be greatly enhanced. We show that time fluctuations may become stronger than other forms of equilibrium quantum fluctuations if the quench is performed close to a critical point. For sufficiently relevant operators the full distribution function of dynamically evolving observable expectation values, becomes a universal function uniquely characterized by the critical exponents and the boundary conditions. At regular points of the phase diagram and for non sufficiently relevant operators the distribution becomes Gaussian. Our predictions are confirmed by an explicit calculation on the quantum Ising model.

description: We investigate the properties of electronic states and optical transitions in hexagonal GaAs quantum dots within AlGaAs nanowires. Such dots are particularly interesting due to their high degree of symmetry. A streamlined postsymmetrization technique based on class operators (PTCO) is developed which enables one to benefit in one run from the insight brought by the Maximal symmetrization and reduction of fields (MSRF) approach reported by Dalessi et al. [Phys. Rev. B 81, 125106 (2010)], after having solved the Schrödinger equation. Definite advantages of the PTCO are that it does not require having to modify any existing code for the calculation of the electronic structure, and that it allows to numerically test for elevated symmetries. We show in the frame of a 4-band k.p model that despite the fact that the D6h symmetry of the nanostructure is broken at the microscopic level by the underlying Zinc Blende crystal structure, the effect is quite small. Most of the particularities of the electronic states and their optical emission can be understood by symmetry elevation to D6h and the presence of approximate azimuthal and radial quantum numbers.
