description: We consider the holographic complexity conjectures for de-Sitter invariant states in a quantum field theory on de Sitter space, dual to asymptotically anti-de Sitter geometries with de Sitter boundaries. The bulk holographic duals include solutions with or without a horizon. If we compute the complexity from the spatial volume, we find results consistent with general expectations, but the conjectured bound on the growth rate is not saturated. If we compute complexity from the action of the Wheeler-de Witt patch, we find qualitative differences from the volume calculation, with states of smaller energy having larger complexity than those of larger energy, even though the latter have bulk horizons.

description: We describe our recent progress in modeling supernova-fallback disks and neutron star (NS) atmospheres. We present a first detailed spectrum synthesis calculation of a SN-fallback disk composed of iron. We assume a thin disk with a radial structure described by the alpha-disk model. The vertical structure and emission spectrum are computed self-consistently by solving the structure equations simultaneously with the radiation transfer equations under non-LTE conditions. We describe the properties of a specific disk model and discuss various effects on the emergent UV/optical spectrum. We investigate Compton scattering effects on the thermal spectrum of NSs. In addition, we constructed a new generation of metal line-blanketed non-LTE model atmospheres for NSs. It is compared to X-ray burst spectra of EXO0748-676. It is possible that the gravitational redshift, deduced from absorption lines, is lower (z=0.24) than hitherto assumed (z=0.35). Accordingly, this would result in NS mass and radius lower limits of M>1.63Msun and R>13.8 km.

Discovery of doubly-charmed Xi_{cc} baryon implies a stable (b b ubar dbar) tetraquark

description: Recently LHCb discovered the first doubly-charmed baryon $Ξ_{cc}^{++} = ccu$ at $3621.40 \pm 0.78$ MeV, very close to our theoretical prediction. We use the same methods to predict a doubly-bottom tetraquark $T(bb\bar u\bar d)$ with $J^P{=}1^+$ at $10,389\pm 12$ MeV, 215 MeV below the $B^-\bar B^{*0}$ threshold and 170 MeV below threshold for decay to $B^-\bar B^0 γ$. The $T(bb\bar u\bar d)$ is therefore stable under strong and electromagnetic (EM) interactions and can only decay weakly, the first exotic hadron with such a property. On the other hand, the mass of $T(cc\bar u\bar d)$ with $J^P{=}1^+$ is predicted to be $3882\pm12$ MeV, 7 MeV above the $D^0 D^{*+}$ threshold and 148 MeV above $D^0 D^+ γ$ threshold. $T(bc\bar u\bar d)$ with $J^P{=}0^+$ is predicted at $7134\pm13$ MeV, 11 MeV below the $\bar B^0 D^0$ threshold. Our precision is not sufficient to determine whether $bc\bar u\bar d\,$ is actually above or below the threshold. It could manifest itself as a narrow resonance just at threshold.

A Model for the Quantitative Assessment of Freedom of Choice in Adventure Digital Games

Year: 2019

description: The concept of freedom in player interaction with digital games, the nature of the choices that make it up and the subjective assessment as to whether a game is considered free-form or structured are at the heart of the interest of this paper. Free-form games that give room to many different playergenerated gameplay paths may amuse a player, while structured games that constrain players to follow a single path to one objective may bore them, thus resulting in different styles of interaction with this specific type of digital media. The aim of this study is to contribute to formalizing a concept of freedom of choice, and be able to evaluate its presence/absence in different adventure digital games; more specifically, the research aims at the formalization and, eventually, at the quantitative assessment of a concept of freedom of choice in free-form and structured adventure digital games, and attempts to arrive at a typology that allows different adventure digital games to be placed at various points on an axis between totally free-form activity and formally structured goal-driven activity. This effort, at the same time, is contextualized within a broader research plan for using adventure games as digital media-based learning frameworks, with a view to ultimately taking stock of player experience and interaction drivers, such as freedom of choice, as enablers for better player/learner engagement and more effective learning through these media.

description: Trapped ion technology has seen advances in performance, robustness, and versatility over the last decade. With increasing numbers of trapped ion groups world-wide, a myriad of trap architectures are currently in use. Applications of trapped ions include: quantum simulation, computing and networking, time standards and fundamental studies in quantum dynamics. Design of such traps is driven by these various research aims, but some universally desirable properties have lead to the development of ion trap foundries. The excellent control achievable with trapped ions and the ability to do photonic-readout, has allowed progress on quantum networking using entanglement between remotely situated ion-based nodes. Here we present a selection of trap architectures currently in use by the community and present their most salient characteristics, identifying features particularly suited for quantum networking. We also discuss our own in-house research efforts aimed at long-distance trapped ion-networking.

description: Dirac leptogenesis (or Dirac neutrinogenesis), in which neutrinos are purely Dirac particles, is an interesting alternative to the standard leptogenesis scenario. In its supersymmetric version, the modified form of the superpotential required for successful baryogenesis contributes new, generically non-flavor-diagonal terms to the slepton and sneutrino mass matrices. In this work, we examine how current experimental bounds on flavor-changing effects in the lepton sector (and particularly the bound on Mu -> e Gamma) constrain Dirac leptogenesis and we find that it is capable of succeeding with superpartner masses as low as 100 GeV. For such light scalars and electroweakinos, upcoming experiments such as MEG are generically expected to observe signals of lepton flavor violation.

It is based on a 2-D Monte Carlo approach, that includes a general description of the symmetric and antisymmetric parts of the diffusion tensor, thus, properly treating the particle drift effects as well as convection within the solar wind and adiabatic energy loss. The model was tuned in order to fit 1) the data observed outside the ecliptic plane at several distances from the Earth and 2) the spectra observed near the Earth for both, high and low solar activity periods. Great importance was given to description of polar regions of the heliosphere. We present the flux for protons, antiprotons and helium nuclei computed along the solar cycle 23-24 in comparison with experimental observations and prediction for the full solar cycle 24.

description: This study focused on interactive media as a socialization agent. The general study objective was to establish influence of WhatsApp mobile application on adolescents, while specific study objectives were; to establish the level of effectiveness of parents/guardians in monitoring adolescents WhatsApp use, assess motivations behind adolescents WhatsApp preference and establish how adolescents access WhatsApp mobile application. Qualitative research approach was used. Data was collected through; semi-structured interviews, participant observation, informal conversations, and focus group discussions. Convenient sampling was used to ease accessibility of target audience. Thematic analysis as qualitative data analysis strategy was used. Data was presented in form of narratives. It was established that parents do not monitor adolescents as they use WhatsApp application, reasons such as parents not being technological savvy, their negative attitude towards learning communication technologies and too much trust on adolescents contributed to lack of monitoring adolescents interactions on WhatsApp. WhatsApp influences were; addiction which resulted in irregular sleeping patterns among adolescents and interference on their studies. Erosion of family values and anti-social behaviour among adolescents were also noted as effect of WhatsApp addiction. The study established that, adolescents’ preferences to use the application were; popularity of WhatsApp hence viewed as trendy and fashionable.

Heating and cooling in the Perseus cluster core

description: It is well known that the radiative cooling time of the hot X-ray emitting gas in the cores of most clusters of galaxies is less than 10^10 yr. In many clusters the gas temperature also drops towards the centre. If we draw a causal connection between these two properties then we infer the presence of a cooling flow onto the central galaxy. High spectral resolution XMM-Newton data and high spatial resolution Chandra data, show however a lack of X-ray emitting gas below about one third of the cluster virial temperature. The explanation is that some form of heating balances cooling. The smoothness and similarity of the cooling time profiles and the flatness of the required heating profiles all indicate that we must seek a relatively gentle, quasi-continuous (on timescales <10^8 yr), distributed heat source. The likely such source is the central black hole and its powerful jets which create bubble-like cavities in the inner hot gas. We briefly review the general heating and cooling statistics in an X-ray bright sample of cluster before we discuss the detailed situation in the Perseus cluster, the X-ray brightest cluster in the Sky.

description: We present the submatrix method, a highly parallelizable method for the approximate calculation of inverse p-th roots of large sparse symmetric matrices which are required in different scientific applications. We follow the idea of Approximate Computing, allowing imprecision in the final result in order to be able to utilize the sparsity of the input matrix and to allow massively parallel execution. For an n x n matrix, the proposed algorithm allows to distribute the calculations over n nodes with only little communication overhead. The approximate result matrix exhibits the same sparsity pattern as the input matrix, allowing for efficient reuse of allocated data structures. We evaluate the algorithm with respect to the error that it introduces into calculated results, as well as its performance and scalability. We demonstrate that the error is relatively limited for well-conditioned matrices and that results are still valuable for error-resilient applications like preconditioning even for ill-conditioned matrices. We discuss the execution time and scaling of the algorithm on a theoretical level and present a distributed implementation of the algorithm using MPI and OpenMP. We demonstrate the scalability of this implementation by running it on a high-performance compute cluster comprised of 1024 CPU cores, showing a speedup of 665x compared to single-threaded execution.

description: What happens in an isolated quantum system when both disorder and interactions are present? Over the recent years, the picture of a non-thermalizing phase of matter, the many-localized phase, has emerged as a stable solution. We present a basic introduction to the topic of many-body localization, using the simple example of a quantum spin chain which allows us to illustrate several of the properties of this phase. We then briefly review the current experimental research efforts probing this physics. The largest part of this review is a selection of more specialized questions, some of which are currently under active investigation. We conclude by summarizing the connections between many-body localization and quantum simulations.

Increased Consumerism in a Networked-Nigeria: A Study on the Effect of E-Malls and Social Media on Youth Spending
Creators: name: Awobamise, Ayodeji Olalekan
Publisher: name: Journal of Digital Media & Interaction
Year: 2019

description: This research focuses on identifying how electronic shopping malls and their adverts on social networking sites might be affecting consumer spending with particular reference to Nigerian youths. The study made use of the quantitative methodology - 1,600 questionnaires were distributed and 1,349 were considered suitable for use in this study after discarding damaged or incorrectly filled questionnaires. This study adopted a multi-disciplinary approach when selecting the relevant theories to serve as the backdrop for the study; shopping preference theory and technological determinism were used as the theoretical background to the thesis. At the end of this study it was proven that there is indeed a relationship between online shopping malls and youth spending patterns. It was proven that exposure to social media and online shopping malls via social media has increased spending among Nigerian youths.

Survival of Nature's Rarest Isotope 180Ta under Stellar Conditions

description: The nucleosynthesis of nature's rarest isotope 180Ta depends sensitively on the temperature of the astrophysical environment because of depopulation of the long-living isomeric state via intermediate states to the short-living ground state by thermal photons. Reaction rates for this transition have been measured in the laboratory. These ground state rates understimate the stellar rates dramatically because under stellar conditions intermediate states are mainly populated by excitations from thermally excited states in 180mTa. Full thermalization of 180Ta is already achieved for typical s-process temperatures around kT = 25 keV. Consequently, for the survival of 180Ta in the s-process fast convective mixing is required which has to transport freshly synthesized 180Ta to cooler regions. In supernova explosions 180Ta is synthesized by photon- or neutrino-induced reactions at temperatures above T9 = 1 in thermal equilibrium; independent of the production mechanism, freeze-out from thermal equilibrium occurs at kT approx 40 keV, and only 35 +- 4 % of the synthesized 180Ta survive in the isomeric state.

description: E-mail marketing is a digital marketing channel that enables communication between companies and their customers or future/new customers. In a world where social media are more present than ever in our everyday lives, it was expected that e-mail marketing as a marketing tool would disappear. However, we observe just the opposite.This research presents the main results from the evaluation of an e-mail marketing communication campaign aimed at “InnovAction” magazine (an annual technological publication produced by Altice Labs). The target audience of this campaign includes the guests of the second-anniversary party of the company, universities, partners, customers, and subscribers, with a total of 1434 people.Based on the campaign evaluation results, it was concluded that the size of the e-mail marketing campaign and the fact that it had an event associated to the release of the product (e.g. company’s anniversary) were major influence factors on the e-mail marketing campaign results. It was also concluded that the company is of great value to their customers and subscribers and that InnovAction contributed to this recognition as a vehicle to share the most relevant technological developments and knowledge throughout the group’s operations all over the world.

description: A new generation of cold atom experiments trapping atomic mixtures in species selective optical potentials opens up the intriguing possibility to create systems in which different atoms live in different spatial dimensions. Inspired by this, we investigate a mixed dimensional Bose polaron consisting of an impurity particle moving in a two-dimensional (2D) layer immersed in a 3D Bose-Einstein condensate (BEC), using a theory that includes the mixed dimensional vacuum scattering between the impurity and the bosons exactly. We show that similarly to the pure 3D case, this system exhibits a well-defined polaron state for attractive boson-impurity interaction that evolves smoothly into a mixed-dimensional dimer for strong attraction, as well as a well-defined polaron state for weak repulsive interaction, which becomes over-damped for strong interaction. We furthermore find that the properties of the polaron depend only weakly on the gas parameter of the BEC as long as the Bogoliubov theory remains a valid description for the BEC. This indicates that higher order correlations between the impurity and the bosons are suppressed by the mixed dimensional geometry in comparison to a pure 3D system, and that the mixed dimensional polaron has universal properties in the unitarity limit of the impurity-boson interaction.

description: Surveys of distant galaxies with the Hubble Space Telescope and from the ground have shown that there is only mild evolution in the relationship between radial size and stellar mass for galactic disks from z~1 to the present day. Using a sample of nearby disk-dominated galaxies from the Sloan Digital Sky Survey (SDSS), and high redshift data from the GEMS (Galaxy Evolution from Morphology and SEDs) survey, we investigate whether this result is consistent with theoretical expectations within the hierarchical paradigm of structure formation. The relationship between virial radius and mass for dark matter halos in the LCDM model evolves by about a factor of two over this interval. However, N-body simulations have shown that halos of a given mass have less centrally concentrated mass profiles at high redshift. When we compute the expected disk size-stellar mass distribution, accounting for this evolution in the internal structure of dark matter halos and the adiabatic contraction of the dark matter by the self-gravity of the collapsing baryons, we find that the predicted evolution in the mean size at fixed stellar mass since z~1 is about 15-20 percent, in good agreement with the observational constraints from GEMS. At redshift z~2, the model predicts that disks at fixed stellar mass were on average only 60% as large as they are today. Similarly, we predict that the rotation velocity at a given stellar mass (essentially the zero-point of the Tully-Fisher relation) is only about 10 percent larger at z~1 (20 percent at z~2) than at the present day.

description: The existence of nonzero periodic travelling wave solutions for a general discrete nonlinear Schrödinger equation (DNLS) on finite one-dimensional lattices is proved. The DNLS features a general nonlinear term and variable range of interactions going beyond the usual nearest-neighbour interaction.

description: We explore the effects of an applied strong external magnetic field in a three flavor massless color superconductor. The long-range component of the B field that penetrates the superconductor enhances some quark condensates, leading to a different condensation pattern. The external field also reduces the flavor symmetries in the system, and thus it changes drastically the corresponding low energy physics. Our considerations are relevant for the study of highly magnetized compact stars.

description: In this paper we study the angular distribution of the rare B decay $B \to K^*_2 (\to K π) l^+ l^-$, which is expected to be observed soon. We use the standard effective Hamiltonian approach, and use the form factors that have already been estimated for the corresponding radiative decay $B \to K^*_2 γ$. The additional form factors that come into play for the dileptonic channel are estimated using the large energy effective theory (LEET), which enables one to relate the additional form factors to the form factors for the radiative mode. Our results provide, just like in the case of the $K^*(892)$ resonance, an opportunity for a straightforward comparison of the basic theory with experimental results which may be expected in the near future for this channel.

description: This article reports on the design and evaluation of player experiences in relation to a location-based game (LBG). LBGs seek to move gamified play into the “real world” of cities, parks, and other locations. These games are played in everyday places, where game information is tied to specific locations (Magerkurth et al, 2005). This connection to real-world physicality makes the game experience multidimensional and fun for players of different ages. Yet, to be able to envision and create an urban gamescape means that a set of criteria must be met. The unique challenge of creating and orchestrating LBG experiences requires a certain sensitivity from its designers to the multiple factors that must be considered. These may include—but are not limited to—factors such as the city’s infrastructure, the flows of urban traffic, the maintenance of recreational areas, and human-related factors such as cooperation with the city administration. The game introduced in this article—Sigrid-Secrets—represents an urban game adventure built upon the platform of geocaching. We approach the game with a focus on its potential learning affordances. We ask how the pitfalls in creating opportunities for learning through LBGs could be avoided, especially when designing pedagogic aims into an urban gaming experience fit for school-aged children.

description: The presence of methyl alcohol or methanol (CH$_3$OH) in several astrophysical environments has been characterized by its high abundance that depends on both the production rate and the destruction rate. In the present work, the photoionization and photodissociation processes of methanol have been experimentally studied, employing soft X-ray photons (100-310 eV) from a toroidal grating monochromator (TGM) beamline of the Brazilian Synchrotron Light Laboratory (LNLS). Mass spectra were obtained using the photoelectron photoion coincidence (PEPICO) method. Kinetic energy distribution and abundances for each ionic fragment have been obtained from the analysis of the corresponding peak shapes in the mass spectra. Absolute photoionization and photodissociation cross sections were also determined. We have found, among the channels leading to ionization, about 11-16% of CH$_3$OH survive the soft X-rays photons. This behavior, together with an efficient formation pathways, may be associated with the high column density observed in star-forming regions. The three main photodissociation pathways are represented by COH$^+$ (or HCO$^+$) ion release (with ejection of H$_2$ + H), the dissociation via C-O bond rupture (with strong charge retention preferentially on the methyl fragment) and the ejection of a single energetic (2-4 eV) proton. Since methanol is very abundant in star forming regions, the produced protons could be an alternative route to molecular hydrogenation or a trigger for secondary dissociation processes or even to promote extra heating of the environment.

Entropy production and work fluctuation relations for a single particle in active bath

description: A colloidal particle immersed in a bath of bacteria is a typical example of a passive particle in an active bath. To model this, we take an overdamped harmonically trapped particle subjected to a thermal and a non-equilibrium noise arising from the active bath. The harmonic well can be attributed to a laser trap or to the small amplitude motion of the sedimented colloid at the bottom of the capillary. In the long time, the system reaches a non-equilibrium steady state that can be described by an effective temperature. By adopting this notion of effective temperature, we investigate whether fluctuation relations for entropy hold. In addition, when subjected to a deterministic time dependent drag, we find that transient fluctuation theorem for work cannot be applied in conventional form. However, a steady state fluctuation relation for work emerges out with a renormalized temperature.

description: My dad Norman Gradwell enlisted in the Black Watch regiment in 1943. After training he embarked for the continent on D-Day+9. After vicious fighting through the Falaise gap [pocket], he was wounded, eventually being sent home. After convalescing he was back in the regiment. He fought through Holland into Germany. He was wounded again on the Holland-Germany border in February 1945. He was transferred from the Black Watch to the Imps, the Lincolnshire regiment after VE Day. He was then transferred to the Warwickshire regiment and was on duty for six months at the Nuremberg trials. He was demobbed in 1946.

description: Baryons made of three heavy quarks become weakly coupled, when all the quarks are sufficiently heavy such that the typical momentum transfer is much larger than Lambda_QCD. We use variational method to estimate masses of the lowest-lying bcc, ccc, bbb and bbc states by assuming they are Coulomb bound states. Our predictions for these states are systematically lower than those made long ago by Bjorken.

description: Although Latin America is well versed in the concept of Open Access, the Open Science movement as a whole has not enjoyed the same level of development in the area. The three countries that have legislated on open access to scientific information (Peru, Argentina, and Mexico) are beginning to develop regulations regarding the opening of data or the development of institutional repositories (which are linked with the so-called Green Open Access route). However, that is not to say that countries which have not legislated about Open Access may not have progressed even a little farther down the road to Open Science, as is the case in Brazil.
A numerical study of a variable-density low-speed turbulent mixing layer

description: Direct numerical simulations of a temporally-developing, low-speed, variable-density, turbulent, plane mixing layer are performed. The Navier-Stokes equations in the low-Mach number approximation are solved using a novel algorithm based on an extended version of the velocity-vorticity formulation used by Kim et al. (1987) for incompressible flows. Four cases with density ratios $s=1, 2, 4$ and 8 are considered. The simulations are run with a Prandtl number of 0.7 and achieve a $Re_λ$ up to 150 during the self-similar evolution of the mixing layer. It is found that the growth rate of the mixing layer decreases with increasing density ratio, in agreement with theoretical models of this phenomenon. Comparison with high-speed data shows that the reduction of the growth rates with increasing the density ratio has a weak dependence with the Mach number. In addition, the shifting of the mixing layer to the low-density stream has been characterized by analyzing one point statistics within the self-similar interval. This shifting has been quantified, and related to the growth rate of the mixing layer under the assumption that the shape of the mean velocity and density profiles do not change with the density ratio. This leads to a predictive model for the reduction of the growth rate of the momentum thickness, which agrees reasonably well with the available data. Finally, the effect of the density ratio on the turbulent structure has been analyzed using flow visualizations and spectra. It is found that with increasing density ratio the longest scales in the high density side are gradually inhibited. A gradual reduction of the energy in small scales with increasing density ratio is also observed.
