Afterglow Emission from Naked Gamma-Ray Bursts

description: We calculate the {\it afterglow} emission for Gamma-Ray Bursts (GRBs) going off in an extremely low density medium, referred to as {\it naked bursts}. Our results also apply to the case where the external medium density falls off sharply at some distance from the burst. The observed afterglow flux in this case originates at high latitudes, i.e. where the angle between the fluid velocity and the observer line of sight is greater than $Γ^{-1}$. The observed peak frequency of the spectrum for naked bursts decreases with observer time as $t^{-1}$, and the flux at the peak of the spectrum falls off as $t^{-2}$. The 2--10 keV $X$-ray flux from a naked burst of average fluence should be observable by the SWIFT satellite for time duration of about $10^3$ longer than the burst variability timescale. The high latitude emission contributes to the early $X$-ray afterglow flux for any GRB, not just naked bursts, and can be separated from the shocked inter-stellar medium (ISM) emission by their different spectral and temporal properties. Measurements of the high latitude emission could be used to map the angular structure of GRB producing shells.

description: Phishing is an ongoing kind of semantic attack that tricks victims into inadvertently sharing sensitive information. In this paper, we explore novel techniques for combating the phishing problem using computational techniques to improve human effort. Using tasks posted to the Amazon Mechanical Turk human effort market, we measure the accuracy of minimally trained humans in identifying potential phish, and consider methods for best taking advantage of individual contributions. Furthermore, we present our experiments using clustering techniques and vote weighting to improve the results of human effort in fighting phishing. We found that these techniques could increase coverage over and were significantly faster than existing blacklists used today.
Where Does Chemistry Go? From Mendeelev Table of Elements to the Big Data Era

description: One hundred and fifty years ago the Russian chemist Dmitri Ivanovich Mendeleev published the first “Periodic System of the Elements” originated to display the periodic trends of the chemical elements known at that time and possibly to predict unknown elements supposed to fill the empty spaces, by predicting their properties. His prevision turned out to be essentially correct. He had about sixty elements in his periodic table of 1869. Other naturally occurring elements were discovered or isolated in the following years, and various further elements have also been produced synthetically. In his honor element 101, discovered in 1905, was named “mendelevium”. The modern periodic table, of 118 elements now, constitutes an important framework for exploring chemical reactions; it provides the basis for the discovery or the synthesis of further new elements and for the development of new theoretical models. Although other chemists at the time of Mendeleev attempted to organize the known chemical elements in a system, the extraordinary and visionary intuition of Mendeleev was to use the trends in his periodic table to predict the properties of missing elements.

description: Chemistry has been identified as the central science: it connects the life sciences with the applied ones. In addition, the degree of branching around chemistry also influences social sciences and intersects in areas such as socio-economics and ethics. The knowledge of scientific concepts for non-specialized audiences, through communication and outreach activities, should be considered as a potent social heritage for humankind. An increase in awareness regarding the benefits based on science and trust would advantage the entire society. Herein, the relevance of a novel way to communicate scientific achievements is described: themes like circular economy and sustainable development are tackled to understand the role of chemistry in developing an ex-novo culture of knowledge.

description: As programming skills increase in demand and utility, the learnability of end-user programming systems is of utmost importance. However, research on learning barriers in programming systems has primarily focused on languages, overlooking potential barriers in the environment and accompanying libraries. To address this, a study of beginning programmers learning Visual Basic.NET was performed. This identified six types of barriers: design, selection, coordination, use, understanding, and information. These barriers inspire a new metaphor of computation, which provides a more learner-centric view of programming system design.

description: Electron transfer reactions constitute one of the main pillars of chemistry and numerous examples can be found in nature and in technological applications. Energy transfer induced reactions are more elusive but equally important in phenomena related with natural photosynthesis and in general when light-matter interactions are relevant. Heterogeneous photocatalysis is generally considered based on electron transfer reactions. In fact, absorption of photons of suitable energy induces formation of photogenerated charges (electron and holes) which in turn initiate redox reactions through interfacial electron transfer to (or from) surface species. However, rare examples of photocatalytic reactions induced by prevailing energy transfer have been recently reported in literature. Investigation in this field may be still defined at a nascent level, and the mechanistic aspects of energy transfer, widely investigated in photochemistry of homogeneous or colloidal systems should be clarified in heterogeneous photocatalysis. In the manuscript the basic principles of energy transfer will be presented along with some known examples. These concepts will be inferred in the field of heterogeneous photocatalysis, by considering the excited solid semiconductor as the energy donor. Some rare examples of energy transfer induced heterogeneous photocatalytic reactions will be presented along with some tentative mechanistic hypotheses.

description: Near-infrared spectroscopy using the new Palomar Integral Field Spectrograph indicates the presence of an AGN (active galactic nucleus) in the ultraluminous infrared galaxy IRAS 08311-2459. The high-velocity wings of the Paschen-alpha hydrogen recombination line are seen to be spatially unresolved, and with no positional offset between red and blue high velocity emission. The [Si VI] coronal line, with a 167 eV excitation potential, is also spatially unresolved with a velocity width comparable to that of the broad component of the Pa-alpha emission. The low velocity component of the Pa-alpha emission is seen to be rotating, and is extended over about 2 kpc. Molecular hydrogen is also extended, and elongated along the maximum velocity gradient, sharing the same rotation profile as the narrow Pa-alpha emission. The simple picture in agreement with the observations is that of an AGN surrounded by a rotating disk of star formation. These observations lend strength to the usage of [Si VI] as a diagnostic of AGN activity in ultraluminous infrared galaxies, and also highlight the utility of integral field spectroscopy in elucidating subtle morphological differences in line emitting regions.

description: Based on an extensive field study of current firefighting practices, we have developed a system called Siren to support tacit communication between firefighters with multiple levels of redundancy in both communication and user alerts. Siren provides a foundation for gathering, integrating, and distributing contextual data, such as location and temperature. It also simplifies the development of firefighting applications using a peer-to-peer network of embedded devices through a uniform programming interface based on the information space abstraction. As a proof of concept, we have developed a prototype context- aware messaging application in the firefighting domain. We have evaluated this application with firefighters and they have found it to be useful for improving many aspects of their current work practices.

description: A software for processing sets of full-color images of biological tissue histological sections is developed. We used histological sections obtained by the method of high-precision layer-by-layer grinding of frozen biological tissues. The software allows restoring the image of the tissue for an arbitrary cross-section of the tissue sample. Thus, our method is designed to create a full-color 3D reconstruction of the biological tissue structure. The resolution of 3D reconstruction is determined by the quality of the initial histological sections. The newly developed technology available to us provides a resolution of up to 5 - 10 μm in three dimensions.

description: In the numerical simulation of the incompressible Navier-Stokes equations different numerical instabilities can occur. While instability in the discrete velocity due to dominant convection and instability in the discrete pressure due to a vanishing discrete LBB constant are well-known, instability in the discrete velocity due to a poor mass conservation at high Reynolds numbers sometimes seems to be underestimated. At least, when using conforming Galerkin mixed finite element methods like the Taylor-Hood element, the classical grad-div stabilization for enhancing discrete mass conservation is often neglected in practical computations. Though simple academic flow problems showing the importance of mass conservation are well-known, these examples differ from practically relevant ones, since specially designed force vectors are prescribed. Therefore we present a simple steady Navier-Stokes problem in two space dimensions at Reynolds number 1024, a colliding flow in a cross-shaped domain, where the instability of poor mass conservation is studied in detail and where no force vector is prescribed.

description: Newspapers serve as a reflection of society, capturing the current events, opinions, and values of a particular community. In this context, the linguistic features used in newspaper texts play a crucial role in conveying information and shaping public discourse. Understanding the nuances of language used in newspapers can provide valuable insights into the cultural, social, and political dynamics of a given society. This article aims to conduct a comparative analysis of linguistic features in newspaper texts in two distinct languages: Karakalpak and English.  By examining the linguistic features in newspaper texts of these two languages, we seek to explore how language is utilized to convey information, express opinions, and engage readers in different cultural contexts.

description: Recently, a canonical change of field variables was proposed that converts the Yang-Mills Lagrangian into an MHV-rules Lagrangian, i.e. one whose tree level Feynman diagram expansion generates CSW rules. We solve the relations defining the canonical transformation, to all orders of expansion in the new fields, yielding simple explicit holomorphic expressions for the expansion coefficients. We use these to confirm explicitly that the three, four and five point vertices are proportional to MHV amplitudes with the correct coefficient, as expected. We point out several consequences of this framework, and initiate a study of its implications for MHV rules at the quantum level. In particular, we investigate the wavefunction matching factors implied by the Equivalence Theorem at one loop, and show that they may be taken to vanish in dimensional regularisation.

description: Classical real-time lattice simulations play an important role in understanding non-equilibrium phenomena in gauge theories and are used in particular to model the prethermal evolution of heavy-ion collisions. Above the Debye scale the classical Yang-Mills (CYM) theory can be matched smoothly to kinetic theory. First we study the limits of the quasiparticle picture of the CYM fields by determining the plasmon mass of the system using 3 different methods. Then we argue that one needs a numerical calculation of a system of classical gauge fields and small linearized fluctuations which correspond to quantum fluctuations, in a way that keeps the separation between the two manifest. We demonstrate and test an implementation of an algorithm with the linearized fluctuations showing that the linearization indeed works and the Gauss's law is conserved.

How Many Galaxies Fit in a Halo? Constraints on Galaxy Formation Efficiency from Spatial Clustering

description: We study galaxy clustering using halo models, where gravitational clustering is described in terms of dark matter halos. At small scales, clustering statistics are dominated by halo density profiles, whereas at large scales, correlations are the result of combining non-linear perturbation theory with halo biasing. Galaxies are assumed to follow the dark matter profiles, and galaxy formation efficiency is given by the number of galaxies as a function of halo mass. This approach leads to generic predictions: the galaxy power spectrum shows a power-law behavior even though the dark matter does not, and the galaxy higher-order correlations show smaller amplitudes at small scales than their dark matter counterparts, as observed in galaxy catalogs. We find that requiring to fit both the second and third order moments of the APM galaxies provides a strong constraint on galaxy formation models. The data at large scales require that galaxy formation be relatively efficient at small masses, m =10^10 Msun/h, whereas data at smaller scales require that the number of galaxies in a halo scale as the mass to the 0.8th power in the high-mass limit. These constraints are independent of those derived from the luminosity function or Tully-Fisher relation. We also predict the power spectrum, bispectrum, and higher-order moments of the mass density field. Although halo models agree well with measurements of the mass power spectrum and the higher order Sp parameters in N-body simulations, the model assumption that halos are spherical leads to disagreement in the configuration dependence of the bispectrum at small scales. We stress the importance of finite volume effects in higher-order statistics and show how they can be estimated in this approach.

Revealing Tripartite Quantum Discord with Tripartite Information Diagram

description: A new measure based on the tripartite information diagram is proposed for identifying quantum discord in tripartite systems. The proposed measure generalizes the mutual information underlying discord from bipartite to tripartite systems, and utilizes both one-particle and two-particle projective measurements to reveal the characteristics of the tripartite quantum discord. The feasibility of the proposed measure is demonstrated by evaluating the tripartite quantum discord for systems with states close to Greenberger-Horne-Zeilinger, W, and biseparable states. In addition, the connections between tripartite quantum discord and two other quantum correlations---namely genuine tripartite entanglement and genuine tripartite Einstein-Podolsky-Rosen steering---are briefly discussed. The present study considers the case of quantum discord in tripartite systems. However, the proposed framework can be readily extended to general N-partite systems.

In the appendix we prove a discrete Poincare inequality for space dimensions greater or equal to two.

In this paper we present a method to construct such functions for generalized Liénard systems by means of linear differential equations. If the degree m of the polynomial is not greater than 3, then the described algorithm works generically. By means of an example we show that this approach can be applied also to polynomials with degree m larger than 3.

description: Digital video is becoming increasingly ubiquitous. However, editing video remains difficult for several reasons: it is a time-based medium, it has dual tracks of audio and video, and current tools force users to work at the smallest level of detail. Based on interviews with professional video editors, we developed a video editor, called Silver, that uses metadata to make digital video editing more accessible to novices. To help users visualize video, Silver provides multiple views with different semantic content and at different levels of abstraction, including storyboard, editable transcript, and timeline views. Silver offers smart editing operations that help users resolve the inconsistencies that arise because of the different boundaries in audio and video.We conducted a preliminary user study to investigate the effectiveness of the Silver smart editing. Participants successfully edited video after only a short tutorial, both with and without smart editing assistance. Our research suggests several ways in which video editing tools could use metadata to assist users in the reuse and composition of video.

description: We propose a simple higher-derivative braneworld gravity model which contains a stable accelerating branch, in the absence of cosmological constant or potential, that can be used to describe the late time cosmic acceleration. This model has similar qualitative features to that of Dvali-Gabadadze-Porrati, such as the recovery of four-dimensional gravity at subhorizon scales, but unlike that case, the graviton zero mode is massless and there are no linearized instabilities. The acceleration rather is driven by bulk gravity in the form of a spin-two ghost condensate. We show that this model can be consistent with cosmological bounds and tests of gravity.

description: A continuum model for the growth of self-assembled quantum dots that incorporates surface diffusion, an elastically deformable substrate, wetting interactions and anisotropic surface energy is presented. Using a small slope approximation a thin film equation for the surface profile that describes facetted growth is derived. A linear stability analysis shows that anisotropy acts to destabilize the surface. It lowers the critical height of flat films and there exists an anisotropy strength above which all thicknesses are unstable. A numerical algorithm based on spectral differentiation is presented and simulation are carried out. These clearly show faceting of the growing islands and a logarithmically slow coarsening behavior.

description: Electronic systems harboring one dimensional helical modes, where the spin and momentum of the electron are locked, have lately become an important field of its own. When coupled to a conventional superconductor, such systems are expected to manifest topological superconductivity, a unique phase that gives rise to exotic Majorana zero modes. Even more interesting are fractional helical states which have not been observed before and which open the route for the realization of the generalized para fermions quasiparticles. Possessing non abelian exchange statistics, these quasiparticles may serve as building blocks in topological quantum computing. Here, we present a new approach to form protected one dimensional helical and fractional helical edge modes in the quantum Hall regime. The novel platform is based on a carefully designed double quantum well structure in a high mobility GaAs based system. In turn, the quantum well hosts two sub bands of 2D electrons, each tuned to the quantum Hall effect regime. By electrostatic gating of different areas of the structure, counter propagating integer, as well as fractional, edge modes, belonging to Landau levels with opposite spins are formed, rendering the modes helical. We demonstrate that due to spin protection, these helical modes remain ballistic, without observed mixing for large distances. In addition to the formation of helical modes, this new platform can be exploited as a rich playground for an artificial induction of compounded fractional edge modes, as well as construction of interferometers based on chiral edge modes.

description: Coordination is important in large-scale software development because of the many people involved and the complex dependencies present in software tasks. Even small improvements in productivity can lead to substantial cost-savings and competitive advantage. But despite great technological advances in software engineering and collaboration tools in recent years, coordination in software development projects continues to be problematic. Traditional theories suggest that team members coordinate by programming their tasks and by communicating with each other, but more recent research also suggest that they coordinate through work familiarity and team cognition mechanisms like shared mental models. This paper reports on the results of a multi-method research investigation of how shared mental models, work familiarity and geographic dispersion affect coordination in software teams. This research is based on three studies conducted at a large telecommunications company: face-to-face interviews, survey, and archival studies. Results show that shared mental models have a positive effect on team coordination and that prior familiarity with the same software parts and projects reduces software development time. Results also indicate that geographic dispersion increases software development time and that the effect of work familiarity is stronger for geographically distributed teams than for co-located teams.

description: Carbon impact estimation software programs have simplified the processes for evaluating the carbon contribution of proposed buildings and can be relatively accurate down to building assembly. However, the simplifying assumption that a building’s embodied carbon is entirely a function of the production and installation, while a building’s carbon-in-use is the province of a building’s operational life can lead to misleading results, and hence, faulty decisions, when the lifespans of a building’s individual materials differ greatly from the building’s lifespan. The primary study became a way to point out those disparities between material life expectancy and carbon impact by studying the impact of three alternative roof assemblies.

We compare our prediction of phase boundaries with the recent measurment, and find a good qualitative agreement.

description: Present paper provides a model of static charged anisotropic fluid sphere in the EinsteinMaxwell- GaussBonnet (EMGB) theory of gravitation. We select KB anstz as the metric co-efficient along with electric field intensity. To develop our model we assume a linear EoS between the radial pressure and the matter density. The model obtained here is found to satisfy the elementary physical requirements like non-negativity nature of pressure and density, the energy conditions, continuity of the metric co-efficients, subliminal velocity of sound and also pressure free hypersurface etc. It may also noted that the solution is free from any kind of singularities.

description: The World Health Organization reports that 2 million people die each year from the effects of air pollution, twice the number of fatalities as from automobile accidents [1]. Direct causes of air pollution related deaths include aggravated asthma, bronchitis, emphysema, lung and heart diseases, and respiratory allergies. While civic agencies address large-scale environmental health problems from the top down by working directly with governments and industries, we explore the design of personal platforms for sensing our natural environment and empowering collective action across blocks, neighborhoods, cities, and nations. In this paper, we report early findings from two field studies of human centered air quality measurements and a simple technology deployment in the spirit of this new Participatory Urbanism: (1) an interview survey of air quality awareness, (2) a field study using several mobile air quality environmental sensors deployed across Accra, Ghana, and (3) the release of an on-the-go air quality awareness mobile SMS tool.
A Brief History of Early Silica Glass: Impact on Science and Society
Creators: name: Rasmussen, Seth C
Publisher: name: Substantia
Year: 2019

description: Silicon in the form of silica is the basis of common glass and its uses predate recorded history. The production of synthetic glass, however, is thought to date back to no earlier than 3000 BCE. This glass technology was not discovered fully fashioned, but grew slowly through continued development of both chemical composition and techniques for its production, manipulation, and material applications. This development had become fairly advanced by the Roman period, resulting in a wide variety of glass vessels and the initial use of glass windows. Following the fall of the Roman Empire, glass grew to new heights in Venice and Murano, where improvements in composition and production resulted in both more chemically stable and clearer forms. The quality of this new glass ushered in the development of lenses and eyeglasses, as well as the greater use of glass as a material for chemical apparatus, both of which changed society and the pursuit of science. Finally, glass in the North developed along different lines to ultimately result in a new form of glass that eventually replaced Venetian glass. This Bohemian glass became the glass of choice for chemical glassware and dominated the chemical laboratory until the final advent of borosilicate glass in the 1880s. A brief overview of the early history of silica glasses from their origins to the development of borosilicate glasses will be presented.

On the question of regular solitons in a Noncommutative Maxwell--Chern--Simons--Higgs model

description: The Maxwell--Chern--Simons model with scaler matter in the adjoint representation is analyzed from an alternative approach which is regular in the $θ\to 0$ limit. This method is complementary to the usual operator formalism applied to explore the nonperturbative solutions which gives singular results in the $θ\to 0$ limit. The absence of any regular non-trivial lumpy solutions satisfying B--P--S bound has been conclusively demonstrated.

A neuronal network model of interictal and recurrent ictal activity

description: We propose a neuronal network model which undergoes a saddle-node bifurcation on an invariant circle as the mechanism of the transition from the interictal to the ictal (seizure) state. In the vicinity of this transition, the model captures important dynamical features of both interictal and ictal states. We study the nature of interictal spikes and early warnings of the transition predicted by this model. We further demonstrate that recurrent seizures emerge due to the interaction between two networks.

The Development of the Periodic Table and its Consequences
Creators: name: Emsley, John
Publisher: name: Substantia
Year: 2019

description: Chemistry is fortunate among the sciences in having an icon that is instantly recognisable around the world: the periodic table. The United Nations has deemed 2019 to be the International Year of the Periodic Table, in commemoration of the 150th anniversary of the first paper in which it appeared. That had been written by a Russian chemist, Dmitri Mendeleev, and was published in May 1869. Since then, there have been many versions of the table, but one format has come to be the most widely used and is to be seen everywhere. The route to this preferred form of the table makes an interesting story.

description: We have studied the effect of cobalt substitution in $L1_{0}$-Fe$_{1-x}$Co$_{x}$Pt films by means of x-ray magnetic circular dichroism (XMCD) and first-principles calculations. The magnetic moments of Fe ($\sim$2.5 $μ_{\rm B}$) and Co ($\sim$1.5 $μ_{\rm B}$) deduced using XMCD were almost unchanged upon Co doping, and the net magnetization decreases with increasing Co content. Calculation also showed that the 3$d$ electrons that have been added by Co substitution occupy only spin-down bands.
Discovering Elements in a Scandinavian Context: Berzelius’s Lärbok i Kemien and the Order of the Chemical Substances
Creators: name: Abbri, Ferdinando
Publisher: name: Substantia
Year: 2019

description: During the Eighteenth century Sweden was a propitious context for the discovery of chemical substances and elements. At the beginning of his scientific career Jöns Jacob Berzelius contributed by his experimental research and discoveries to the preservation of the high scientific profile of his native country. Electrochemistry and the chemical atomic theory marked Berzelius’s scientific life and organized his vision of chemistry and his classification of substances. Berzelius used his Lärbok i Kemien to spread his discoveries and to frame his conception of chemistry. Focusing on Berzelius’s textbook of chemistry the paper tries to enlighten a specific vision of chemical science which was very influential in the first half of the XIX century.

Carl Auer von Welsbach (1858-1929) - A Famous Austrian Chemist Whose Services Have Been Forgotten for Modern Physics
Creators: name: Löffler, Gerd Reinhold
Publisher: name: Substantia

description: Carl Auer von Welsbach (1858-1929) was a chemist and entrepreneur famous beyond the borders of Austria, with good contacts to well-known chemists and physicists in Europe. This is evidenced by his strong correspondence and the shipment of his rare earth preparations to known researchers. In 185 he discovered the elements Neodymium and Praseodymium and in 1905 the elements Ytterbium and Lutetium. In his time he was considered a specialist for the rare earth elements (SE). He received his doctorate from Robert Bunsen in Heidelberg (1880-1882). Spectral analysis was his domain. His ability to neatly separate the chemically very similar SE elements from the minerals (e.g. monazite sand) to the then-known and further developed principle of "fractional crystallization" also made relatively accurate investigations of the magnetic properties of these elements possible. In particular, the chemists and physicists were interested in the question of whether or not the series of SE elements is complete with lutetium. The famous quantum physicist Niels Bohr had made a statement with his atomic model that luteium must be the last element of this sequence in the periodic table of the elements and predicted the magnetic properties. They were confirmed by the experiments with the Auer Welsbach preparations - in particular of the Lutetium - by the physicist Stefan Meyer (1842-1949) in Vienna. In 1925 the physicist and theoretician Friedrich Hund (1886-1997) from Göttingen then succeeded to set up a first quantum mechanical model (Hund's rule), which achieved a good agreement with the experimental results from Vienna. This was an advance in early quantum mechanics, which is also due to the highly pure SE preparations of the chemist Carl Auer von Welsbach.
