description: This report summarizes progress made in understanding properties such as zero-phonon-line energies, emission and absorption polarizations, electron-phonon couplings, strain tuning and hyperfine coupling of single photon emitters in hexagonal boron nitride. The primary aims of this research are to discover the chemical nature of the emitting centres and to facilitate deployment in device applications. Critical analyses of the experimental literature and data interpretation, as well as theoretical approaches used to predict properties, are made. In particular, computational and theoretical limitations and challenges are discussed, with a range of suggestions made to overcome these limitations, striving to achieve realistic predictions concerning the nature of emitting centers. A symbiotic relationship is required in which calculations focus on properties that can easily be measured, whilst experiments deliver results in a form facilitating mass-produced calculations.

description: In this paper, we present preliminary results on the use of deep learning techniques to integrate the users self-body and other participants into a head-mounted video see-through augmented virtuality scenario. It has been previously shown that seeing users bodies in such simulations may improve the feeling of both self and social presence in the virtual environment, as well as user performance. We propose to use a convolutional neural network for real time semantic segmentation of users bodies in the stereoscopic RGB video streams acquired from the perspective of the user. We describe design issues as well as implementation details of the system and demonstrate the feasibility of using such neural networks for merging users bodies in an augmented virtuality simulation.

description: At the beginning some results from the field of graph theory are presented. Next we show how to share a secret that is proper n-coloring of the graph, with the known structure. The graph is described and converted to the form, where colors assigned to vertices form the number with entries from Zn. A secret sharing scheme (SSS) for the graph coloring is proposed. The proposed method is applied to the public-key cryptosystem called "Polly Cracker". In this case the graph structure is a public key, while proper 3-colouring of the graph is a private key. We show how to share the private key. Sharing particular n-coloring (color-to-vertex assignment) for the known-structure graph is presented next.

The Polarization of X-rays from Warped Black Hole Accretion Disks
Creators: name: Abarr, Quincy

Publisher: name: arXiv
Year: 2019
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: It is commonly assumed that in black hole accretion disks the angular momenta of the disk and the black hole are aligned. However, for a significant fraction of stellar mass black holes and supermassive black holes, the momenta may not be aligned. In such systems, the interplay of disk viscosity and general relativistic frame dragging can cause the disk to warp or break into two (or more) distinct planes; this is called the Bardeen-Petterson effect. We have developed a general relativistic ray-tracing code to find the energy spectra and polarization of warped accretion disks, accounting for the emission from the disk and for photons reflecting one or multiple times off the warped accretion disk segments. We find that polarization angle can be used to give a lower limit on the misalignment angle when a previous measurement of the jet, which is thought be aligned with the black hole angular momentum, can be spatially resolved.

description: This article gives a comprehensive description of the fractal geometry of conformally-invariant (CI) scaling curves, in the plane or half-plane. It focuses on deriving critical exponents associated with interacting random paths, by exploiting an underlying quantum gravity (QG) structure, which uses KPZ maps relating exponents in the plane to those on a random lattice, i.e., in a fluctuating metric. This is applied to critical models, like O(N) and Potts models, and to the Stochastic Löwner Evolution (SLE). The multifractal (MF) function f(alpha, c) of the harmonic measure near any CI fractal boundary, is given as a function of the central charge c of the associated CFT. The Hausdorff dimensions D_{H} of a non-simple scaling curve or cluster hull, and D_{EP} of its external perimeter or frontier, are shown to obey the duality equation (D_{H}-1)(D_{EP}-1)=1/4, valid for any c. The universal mixed MF spectrum f(alpha,lambda;c) describing the local spiralling rate lambda and singularity exponent alpha of the potential near any CI scaling curve is given. The duality between simple and non-simple random paths is established via a symmetry of the KPZ quantum gravity map. An extended dual KPZ relation is introduced for the SLE_{kappa}, which commutes with the kappa to kappa'=16/kappa duality. This gives the SLE exponents from simple QG rules, established from the general structure of correlation functions of arbitrary interacting random sets on a random lattice.

description: Two new thiospinels of the type AI2BIICIV3SVI8 were successfully synthesized via a mechanochemical route using binary sulfides and sulfur. Cu2MgSn3S8 and Ag2MgSn3S8 are the first AI2BIICIV3SVI8 compounds with magnesium as divalent cation. The crystal structures of Cu2MgSn3S8 and Ag2MgSn3S8 were refined in the cubic space group Fd3m using X‐ray powder diffraction. According to UV/Vis measurements, a direct optical bandgap of ca. 1.65 eV was determined for both Cu2MgSn3S8 and Ag2MgSn3S8. Temperature‐dependent magnetic susceptibility measurements of the Cu2MgSn3S8 sample indicate diamagnetism. A 119Sn Mössbauer spectrum confirms the tetravalent state of tin, underlining the electron‐precise description.

We discuss the importance of this process for phenomenology of generalized parton distributions. A special attention is given to the sensitivity of physical observables, i.e., diverse asymmetries, to their dependence on scaling variables that allows to map directly the functional two-dimensional surface of generalized parton distributions.

description: Exact diagonalization is a powerful numerical method to study isolated quantum many-body systems. This paper provides a review of numerical algorithms to diagonalize the Hamiltonian matrix. Symmetry and the conservation law help us perform the numerical study efficiently. We explain the method to block-diagonalize the Hamiltonian matrix by using particle number conservation, translational symmetry, particle-hole symmetry, and spatial reflection symmetry in the context of the spin-1/2 XXZ model or the hard-core boson model in a one-dimensional lattice. We also explain the method to study the unitary time evolution governed by the Schrödinger equation and to calculate thermodynamic quantities such as the entanglement entropy. As an application, we demonstrate numerical results that support that the eigenstate thermalization hypothesis holds in the XXZ model.

In the framework of the background-field method, this sector is singled out by computing the effective action for a background N = 2 vector multiplet satisfying a relaxed super self-duality condition. The approach advocated in this letter can be applied, in particular, to the study of the N = 4 super Yang-Mills theory on its Coulomb branch.

Dynamic receptor team formation can explain the high signal transduction gain in E. coli

description: Evolution has provided many organisms with sophisticated sensory systems that enable them to respond to signals in their environment. The response frequently involves alteration in the pattern of movement, such as the chemokinesis of the bacterium Escherichia coli, which swims by rotating its flagella. When rotated counterclockwise (CCW) the flagella coalesce into a propulsive bundle, producing a relatively straight ``run'', and when rotated clockwise (CW) they fly apart, resulting in a ``tumble'' which reorients the cell with little translocation. A stochastic process generates the runs and tumbles, and in a chemoeffector gradient runs that carry the cell in a favorable direction are extended. The overall structure of the signal transduction pathways is well-characterized in E. coli, but important details are still not understood. Only recently has a source of gain in the signal transduction network been identified experimentally, and here we present a mathematical model based on dynamic assembly of receptor teams that can explain this observation.

description: [Highly abridged, from executive summary] As much as NewSpace presents opportunities, there are significant challenges that must be overcome, requiring engagement with policy makers to influence domestic and international space governance. Failure to do so could result in a range of long-lasting negative outcomes for science and space stewardship. How will the Canadian astronomical community engage with NewSpace? What are the implications for NewSpace on the astro-environment, including Earth orbits, lunar and cis-lunar orbits, and surfaces of celestial bodies? This white paper analyzes the rapid changes in space use and what those changes could mean for Canadian astronomers. Our recommendations are as follows: Greater cooperation between the astronomical and the Space Situational Awareness communities is needed. Build closer ties between the astronomical community and Global Affairs Canada (GAC). Establish a committee for evaluating the astro-environmental impacts of human space use, including on and around the Moon and other bodies. CASCA and the Tri-Council should coordinate to identify programs that would enable Canadian astronomers to participate in pay-for-use services at appropriate funding levels. CASCA should continue to foster a relationship with CSA, but also build close ties to the private space industry. Canadian-led deep space missions are within Canada's capabilities, and should be pursued.

title: Production and preservation of boar spermatozoa.
Creators: name: Wood, Charles William
Publisher: name: The Open University
Year: 1980

description: The use of artificial insemination for breeding pigs has developed slowly over the past few years within the United Kingdom. Future development will depend to a large extent, on the ability to maintain and improve on the present conception rates, by improved techniques for the preservation in vitro of boar spermatozoa. This dissertation examines the production, and the methods of preservation of boar spermatozoa. In Section I, the production of spermatozoa is reviewed, from the division of the germ cells within the seminiferous epithelium, through the various stages of development, to the maturation of the spermatozoa within the epididymis. Variation in sperm production rates and sperm output are related to age and strain of boar, ejaculation frequency and environ­mental temperature. These aspects are examined, as are the methods of collection of semen from the boars and the laboratory examination of the spermatozoa. In Section II, a review is undertaken of the methods of extending the life of the spermatozoa when stored in vitro. The advantages of storing spermatozoa 'fresh' as opposed to 'frozen' are discussed, and the various diluents used for storing spermatozoa by each method are examined. The freezing of boar spermatozoa has presented more difficulties than the freezing of bull spermatozoa. The various procedures involved with freezing, including the effects of glycerol, 'holding time' and the use of surfactant agents are investigated. Two experiments are reported. The 1st. experiment investigates the relationship of morphological abnormalities of spermatozoa to conception rates and litter size. The 2nd. experiment examines the effect on acrosomal integrity of the various stages involved with cooling and freezing the spermatozoa.

description: We study the minimally and non-minimally coupled scalar field models as possible alternatives for dark energy, the mysterious energy component that is driving the accelerated expansion of the universe. After discussing the dynamics at both the background and perturbation level, we confront the two models with the latest cosmological data. After obtaining updated constraints on their parameters we perform model selection using the basic information criteria. We found that the $Λ$CDM model is strongly favored when the local determination of the Hubble constant is not considered and that this statement is weakened once local $H_0$ is included in the analysis. We calculate the parameter combination $S_8=σ_8\sqrt{Ω_{m}/0.3}$ and show the decrement of the tension with respect to the Planck results in the case of minimally and non-minimally coupled scalar field models. Finally, for the coupling constant between DE and gravity, we obtain the constraint $ξ\simeq -0.06^{+0.19}_{-0.19}$, approaching the one from solar system tests $|ξ| \lesssim 10^{-2}$ and comparable to the conformal value $ξ=1/6$ at $1σ$ uncertainty.

description: The spin-dependent transport of the electrons tunneling through a resonant tunneling structure with ferromagnetic multi-terminal under dc and ac fields is explored by means of the nonequilibrium Green function technique. A general formulation for the time-dependent current and the time-averaged current is established. As its application the systems with two and three terminals in noncollinear configurations of the magnetizations under dc and ac biases are investigated, respectively. The asymmetric factor of the relaxation times for the electrons with different spin in the central region is uncovered to bring about various behaviours of the TMR. The present three-terminal device is different from that discussed in literature, which is coined as a spin transistor with source. The current-amplification effect is found. In addition, the time-dependent spin transport for the two-terminal device is studied. It is found that the photonic sidebands provide new channels for the electrons tunneling through the barriers, and give rise to new resonances of the TMR, which is called as the photon-asisted spin-dependent tunneling. The asymmetric factor of the relaxation times is observed to lead to additional resonant peaks besides the photon-asisted resonances.

title: Production of monoclonal antibodies to cells isolated from the developing rodent cerebellum and grown in culture
Creators: name: Pigott, R
Publisher: name: The Open University
Year: 1982

description: Conditions previously established for the growth in culture of cells isolated from early postnatal rat cerebella, have been adapted for the growth of similarly isolated cells from mice cerebella, in the belief that such cultures may provide a useful model for studying a number of aspects of neural development. These cultures have been shown to be reproducible, both in terms of plating efficiency and cell-type composition, and survive and develop for at least three weeks in vitro. In an effort to identify cell-type specific antigens, some of which have been implicated in the process of neural recognition, techniques have been developed for the production and detection of monoclonal antibodies to cerebellar cells in culture. The successful production of such antibodies may provide both new cell type specific markers and new experimental tools. Preliminary efforts to characterise one antibody, produced by the methods described, indicate that it recognises an antigen present on filaments in both astrocytes and fibroblastic cells present in cultures of rat cerebellar cells.

description: SPI, the Spectrometer on board the ESA INTEGRAL satellite, to be launched in October 2002, will study the gamma-ray sky in the 20 keV to 8 MeV energy band with a spectral resolution of 2 keV for photons of 1 MeV, thanks to its 19 germanium detectors spanning an active area of 500 cm2. A coded mask imaging technique provides a 2 deg angular resolution. The 16 deg field of view is defined by an active BGO veto shield, furthermore used for background rejection. In April 2001 the flight model of SPI underwent a one-month calibration campaign at CEA in Bruyères le Châtel using low intensity radioactive sources and the CEA accelerator for homogeneity measurements and high intensity radioactive sources for imaging performance measurements. After integration of all scientific payloads (the spectrometer SPI, the imager IBIS and the monitors JEM-X and OMC) on the INTEGRAL satellite, a cross-calibration campaign has been performed at the ESA center in Noordwijk. A set of sources has been placed in the field of view of the different instruments in order to compare their performances and determine their mutual influence. Some of those sources had already been used in Bruyères during the SPI standalone test. For the lowest energy band calibration an X-ray generator has been used. We report on the scientific goals of this calibration activity, and present the measurements performed as well as some preliminary results.

title: The prospects for coal gasification
Creators: name: Jackson, Arnold Terence
Publisher: name: The Open University
Year: 1980

description: The prospects for coal gasification are considered in the light of ever increasing problems of high prices and uncertain supplies of fossil fuels throughout the world. A detailed analysis of the supply and demand for coal and gas in Britain now and in the next decade is an essential part of this work. This needs to be set in the overall context of world supply and demand. The consequences of social and political changes on energy supply are stressed as well as the consequences of technical changes. A review of the present position of coal gasification technology, both surface technology methods and underground coal gasification methods is given in some detail. The advantages of coal gasification compared with electricity production such as energy efficiency, capital cost and environmental impact are considered. The relatively poor position of the coal industry in relation to future markets for coal and the uncertainty surrounding ultimate natural gas reserves are two important factors which are relevant to the development of coal gasification. The domestic gas market is studied in some detail to determine the gas penetration within the various sectors and house types within this market. Future gas demand in the domestic market will be quite different from that in the 1970's. This will be due to several factors including price elasticity, insulation, low energy houses, housing policy, effect of high fuel prices on individual lifestyle etc., and each of these are considered in some detail. A close survey of the impact of various other heating vectors in the domestic sector is given to determine their future effect on gas demand. It is concluded that even allowing for some development of heat pump, CHP and other newer technologies, their effect on reducing future gas demand will be limited. There will remain a need for a substantial gas supply even when North Sea supplies decline. If this is linked to the need for the development of alternative coal markets and the need to promote the nuclear electricity plant programme, then a credible case for coal gasification emerges.

description: Empirical evidence on the Generalized System of Preferences (GSP) for low-income countries generally portrays a rather stark prediction: the program has produced virtually no impact on intended low-income beneficiaries’ exports to high-income countries. This result, based on total merchandise trade, is misleading because it masks three underlying heterogeneities in the program: i) preference structure across countries, ii) pre-existing distortions across sectors, and iii) rules of origin. Using a theoretically consistent gravity equation for sector- and product-level trade over 1962–2010, we illustrate that the GSP has delivered significant positive effects for lowincome countries’ agricultural exports (but not necessarily for their nonagricultural exports) to developed countries.

description: The conductance modulations in spin field-effect transistors under finite bias voltages were studied. It was shown that when a finite bias voltage is applied between two terminals of a spin field-effect transistor, the spin precession states of injected spin-polarized electrons in the semiconductor channel of the device will depend not only the gate-voltage controlled Rashba spin-orbit coupling but also depend on the bias voltage and, hence, the conductance modulation in the device due to Rashba spin-orbit coupling may also depend sensitively on the bias voltage.

description: A recent study has demonstrated that phase separation in binary liquid mixtures is arrested in the presence of elastic networks and can lead to a nearly uniformly-sized distribution of the dilute-phase droplets. At longer timescales, these droplets exhibit a directional preference to migrate along elastic property gradients to form a front of dissolving droplets [K. A. Rosowski, T. Sai, E. Vidal-Henriquez, D. Zwicker, R. W. Style, E. R. Dufresne, Elastic ripening and inhibition of liquid-liquid phase separation, Nature Physics (2020) 1-4]. In this work, we develop a complete theoretical understanding of this phenomenon in nonlinear elastic solids by employing an energy-based approach that captures the process at both short and long timescales to determine the constitutive sensitivities and the dynamics of the resulting front propagation. We quantify the thermodynamic driving forces to identify diffusion-limited and dissolution-limited regimes in front propagation. We show that changes in elastic properties have a nonlinear effect on the process. This strong influence can have implications in a variety of material systems including food, metals, and aquatic sediments, and further substantiates the hypothesis that biological systems exploit such mechanisms to regulate important function.

The magneto-optics in quantum wires comprised of vertically stacked quantum dots: A calling for the magnetoplasmon qubits

description: A deeper sense of advantages over the planar quantum dots and the foreseen applications in the single-electron devices and quantum computation have given vertically stacked quantum dots (VSQD) a width of interest. Here, we embark on the collective excitations in a quantum wire made-up of vertically stacked, self-assembled InAs/GaAs quantum dots in the presence of an applied magnetic field in the symmetric gauge. We compute and illustrate the influence of an applied magnetic field on the behavior characteristics of the density of states, Fermi energy, and collective (magnetoplasmon) excitations [obtained within the framework of random-phase approximation (RPA)]. The Fermi energy is observed to oscillate as a function of the Bloch vector. Remarkably, the intersubband single-particle continuum splits into two with a collective excitation propagating within the gap. This is attributed to the (orbital) quantum number owing to the applied magnetic field. Strikingly, the alteration in the well- and barrier-widths can enable us to customize the excitation spectrum in the desired energy range. These findings demonstrate, for the very first time, the viability and importance of studying the VSQD subjected to an applied magnetic field. The technological promise that emerges is the route to devices exploiting magnetoplasmon qubits as the potential option in designing quantum gates for the quantum communication networks.

Analisa as implicações da adoção do sistema proposto tendo em vista sua funcionabilidade e implicações quanta a pessoal, orçamento, tempo e espaço físico em relação à sua implantação, manutenção e acessibilidade. Através de estudos de dispersão da literatura em relação ao sistema proposto conclui-se que o Sistema pretendendido não reuniria sob o mesmo numero de classificação, a nivel satisfatório, os periódicos que publicam trabalhos de um mesmo assunto, periódicos solicitados para empréstimo por um mesmo indivíduo e nem os periódicos considerados importantes por especialistas de areas especificas. Sugere várias alternativas comparando as vantagens e desvantagens de cada uma delas.
