description: By depleting the ionizing photon budget available to expand cosmic HII regions, recombining systems (or Lyman limit systems) can have a large impact during (and following) cosmic reionization. Unfortunately, directly resolving such structures in large-scale reionization simulations is computationally impractical. Instead, here we implement a sub-grid prescription for tracking inhomogeneous recombinations in the intergalactic medium. Building on previous work parameterizing photo-heating feedback on star-formation, we present large-scale, semi-numeric reionization simulations which self-consistently track the local (sub-grid) evolution of both sources and sinks of ionizing photons. Our simple, single-parameter model naturally results in both an extended reionization and a modest, slowly-evolving emissivity, consistent with observations. Recombinations are instrumental in slowing the growth of large HII regions, and damping the rapid rise of the ionizing background in the late stages of (and following) reionization. As a result, typical HII regions are smaller by factors of $\sim 2-3$ throughout reionization. The large-scale ($k\lesssim 0.2\text{ Mpc$^{-1}$}$) ionization power spectrum is suppressed by factors of $\gtrsim 2-3$ in the second half of reionization. Therefore properly modeling recombinations is important in interpreting virtually all reionization observables, including upcoming interferometry with the redshifted 21 cm line. Consistent with previous works, we find the clumping factor of ionized gas to be $C_{\rm HII}\sim 4$ at the end of reionization.

description: A lo largo de sus casi 20 años de carrera, Taylor Swift ha acostumbrado dejar mensajes ocultos, conocidos como 'Easter Eggs', para sus fans. Los y las seguidoras de la cantante, conocidas como “Swifties”, acostumbran buscar estos mensajes, descifrarlos y darles significado. Por su parte, Taylor Swift ha alentado este comportamiento, y hoy en día la comunidad de swifties se ha convertido en un grupo donde constantemente se están generando teorías sobre lo que sigue, ya sea en la carrera de Swift o en su vida personal. El presente proyecto pretende explicar cómo los Easter Eggs que Taylor Swift deja en sus productos, como su música, videos musicales, entrevistas y más, afecta las relaciones entre los fans y con la misma Taylor Swift. Haciendo un análisis y recopilación de experiencias de las fans, se logra una visión más amplia de cómo funcionan las comunidades de fans en línea y cómo forman comunidad más allá del fandom.

description: This article presents new local and global gradient estimates of Li-Yau type for positive solutions to a class of nonlinear elliptic equations on smooth metric measure spaces involving the Witten Laplacian. The estimates are derived under natural lower bounds on the associated Bakry-Émery Ricci curvature tensor and find utility in proving general Harnack inequalities and Liouville-type theorems to mention a few. The results here unify, extend and improve various existing results in the literature for special nonlinearities already of huge interest and applications. Some important consequences are presented and discussed.

It's a man's world: an analysis of the value of the television personality to UK public service broadcasting in the digital age [1999-2011]
Creators: name: Charlesworth, Diane
Publisher: name: University of Lincoln
Year: 2023
Subjects: P301 - Television studies

description: The focus of the thesis is an examination of the role of the television personality within the context of recent debates about public service broadcasting and the economic consequences of moving into the digital age. In particular, those broadcasters intent on maintaining a public service identity, notably the BBC and C4, have the task of demonstrating their appeal and purpose beyond entertainment and consumer choice to a commitment to processes of social and cultural engagement. Certain figures on television have a regularity and constancy of presence within and across genres. Their appearance is familiar, their appeal ‘everyday’, whilst generating a sense of authority and authenticity. Drawing on the work of John Langer (1981) expanded upon by others [Ellis: 1982; Bennett: 2008 & 2010; Bennett & Holmes: 2010] this has been identified as a specific and deliberate part of televisual address to its audiences. The research focuses on the examples of Jamie Oliver, Jonathan Ross and David Dimbleby and their strategic development by either C4 or the BBC at particular points during the period 1999-2011, through analysis of industry debate and programme discourses. It is argued that between them, they represent constructions of nationhood, citizenship, culture, different embodiments of masculinity and the role of television as part of social history and nostalgia. These discursive values, it is argued, are increasingly important as a part of PSB channel and broadcaster branding in a fragmenting attention economy.

description: We investigate the influence of Asymptotic Giant Branch stars on integrated colours of star clusters of ages between ~100 Myr and a few gigayears, and composition typical for the Magellanic Clouds. We use state-of-the-art stellar evolution models that cover the full thermal pulse phase, and take into account the influence of dusty envelopes on the emerging spectra. We present an alternative approach to the usual isochrone method, and compute integrated fluxes and colours using a Monte Carlo technique that enables us to take into account statistical fluctuations due to the typical small number of cluster stars. We demonstrate how the statistical variations in the number of Asymptotic Giant Branch stars and the temperature and luminosity variations during thermal pulses fundamentally limit the accuracy of the comparison (and calibration, for population synthesis models that require a calibration of the Asymptotic Giant Branch contribution to the total luminosity) with star cluster integrated photometries. When compared to observed integrated colours of individual and stacked clusters in the Magellanic Clouds, our predictions match well most of the observations, when statistical fluctuations are taken into account, although there are discrepancies in narrow age ranges with some (but not all) set of observations.

description: Traditional methods for generating orbital angular momentum (OAM) light include holographic diffraction gratings, vortex phase plate and spatial light modulator. In this article, we report a new method for high efficient OAM light generation. By pumping an external cavity contains a quasi phase matching nonlinear crystal with a fundamental OAM carrying light and properly aligning the cavity, mode matching between the pump light and the cavitys higher order Laguerre-Gaussian (LG) mode is achieved, conversion efficiency up to 10.3 percentage have been obtained. We have demonstrated that the cavity can stably operate at its higher order LG mode just as Gaussian mode for the first time. The SHG light possesses a doubled OAM value with respect to the pump light. The parameters that affect the beam quality and conversion efficiency are discussed in detail. Our work opens a brand new field in laser optics, and makes the first step toward high efficiency OAM light processing.

On the Foundational Equations of the Classical Theory of Electrodynamics
Creators: name: Mansuripur, Masud
Publisher: name: arXiv
Year: 2014
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: A close examination of the Maxwell-Lorentz theory of electrodynamics reveals that polarization and magnetization of material media need not be treated as local averages over small volumes - volumes that nevertheless contain a large number of electric and/or magnetic dipoles. Indeed, Maxwell's macroscopic equations are exact and self-consistent mathematical relations between electromagnetic fields and their sources, which consist of free charge, free current, polarization, and magnetization. When necessary, the discrete nature of the constituents of matter and the granularity of material media can be handled with the aid of special functions, such as Dirac's delta-function. The energy of the electromagnetic field and the exchange of this energy with material media are treated with a single postulate that establishes the Poynting vector S = ExH as the rate of flow of electromagnetic energy under all circumstances. Similarly, the linear and angular momentum densities of the fields are simple functions of the Poynting vector that can be unambiguously evaluated at all points in space and time, irrespective of the type of material media, if any, that might reside at various locations. Finally, we examine the Einstein-Laub force- and torque-density equations, and point out the consistency of these equations with the preceding postulates, with the conservation laws, and with the special theory of relativity. The set of postulates thus obtained constitutes a foundation for the classical theory of electrodynamics.

Molecule-optimized Basis Sets and Hamiltonians for Accelerated Electronic Structure Calculations of Atoms and Molecules

Year: 2014
Subjects: subject: Chemical Physics (physics.chem-ph)

description: Molecule-optimized basis sets, based on approximate natural orbitals, are developed for accelerating the convergence of quantum calculations with strongly correlated (multi-referenced) electrons. We use a low-cost approximate solution of the anti-Hermitian contracted Schr{ö}dinger equation (ACSE) for the one- and two-electron reduced density matrices (RDMs) to generate an approximate set of natural orbitals for strongly correlated quantum systems. The natural-orbital basis set is truncated to generate a molecule-optimized basis set whose rank matches that of a standard correlation-consistent basis set optimized for the atoms. We show that basis-set truncation by approximate natural orbitals can be viewed as a one-electron unitary transformation of the Hamiltonian operator and suggest an extension of approximate natural-orbital truncations through two-electron unitary transformations of the Hamiltonian operator, such as those employed in the solution of the ACSE. The molecule-optimized basis set from the ACSE improves the accuracy of the equivalent standard atom-optimized basis set at little additional computational cost. We illustrate the method with the potential energy curves of hydrogen fluoride and diatomic nitrogen. Relative to the hydrogen fluoride potential energy curve from the ACSE in a polarized triple-zeta basis set, the ACSE curve in a molecule-optimized basis set, equivalent in size to a polarized double-zeta basis, has a nonparallelity error of 0.0154 a.u. which is significantly better than the nonparallelity error of 0.0252 a.u. from the polarized double-zeta basis set.

For these polytopes we describe the cohomology ring of the corresponding moment-angle manifold $\mathcal Z_P$ and explore some topological consequences of this calculation. We also examine minimal non-Golodness for their Stanley--Reisner rings and relate it to the property of $\mathcal Z_P$ being a connected sum of sphere products.

description: Let $π$ be a factor code from a one dimensional shift of finite type $X$ onto an irreducible sofic shift $Y$. If $π$ is finite-to-one then the number of preimages of a typical point in $Y$ is an invariant called the degree of $π$. In this paper we present an algorithm to compute this invariant. The generalized notion of the degree when $π$ is not limited to finite-to-one factor codes, is called the class degree of $π$. The class degree of a code is defined to be the number of transition classes over a typical point of $Y$ and is invariant under topological conjugacy. We show that the class degree is computable.

liver proteome

description: The marine biotoxin okadaic acid (OA) is produced by dinoflagellates and enters the human food chain by accumulating in the fatty tissue of filter-feeding shellfish. Consumption of highly contaminated shellfish can lead to diarrheic shellfish poisoning. However, apart from the acute effects in the intestine, OA can also provoke toxic effects in the liver, as it is able to pass the intestinal barrier into the blood stream. However, molecular details of OA-induced hepatotoxicity are still insufficiently characterized, and especially at the proteomic level data are scarce. In this study, we used human HepaRG liver cells and exposed them to non-cytotoxic OA concentrations for 24 hours. Global changes in protein expression were analyzed using 2-dimensional gel electrophoresis in combination with mass-spectrometric protein identification. The results constitute the first proteomic analysis of OA effects in human liver cells and indicate, amongst others, that OA affects the energy homeostasis, induces oxidative stress, and induces cytoskeletal changes.

Cultural Manifestattions in mental disorders

description: This paper aimed to examine whether the mental disorders observed in the Western cultural context maintain the same clinical profile in different cultural contexts. This issue was explored in Cross-cultural Psychology and in Clinical Psychology. Our goal consists in understanding the impact of culture on the expression of symptoms in mental disorders, particularly in schizophrenia, depression and anxiety; along with cultural expressions of the meaning or signification of mental illness. We also examined the differences in the social and psychological effects of mental illness from one culture to another. Additionally, we analysed the problem of treating mental disorders in different cultural contexts. Our main conclusions consist in that culture expresses itself in symptoms of mental disorders, and the results of numerous studies emphasized the need for cultural adaptation of diagnosis and treatment of mental illnesses. It was also found that the culture of the mental patient determines the degree of his psychological and social suffering. Based on the above, we recommend that culture should be taken into account in all stages of mental illness, whether it is related to diagnosis or treatment.

description: Possible phase transition of strongly interacting matter from hadron to a quark-gluon plasma state have in the past received considerable interest. The clustering of color sources provides a framework of the the partonic interactions in the initial stage of the collisions. The onset of de-confinement transition is identified by the spanning percolation cluster in 2D percolation. In this talk results are presented both for the multiplicity and the elliptic flow at RHIC and LHC energies. The thermodynamic quantities temperature, equation of state and transport coefficient are obtained in the framework of clustering of color sources. It is shown that the results are in excellent agreement with the recent lattice QCD calculations(LQCD).

Subjects: subject: History and Overview (math.HO)

description: We report on a pedagogical experiment to make mathematics easy by changing its philosophy. The Western philosophy of math originated in religious beliefs about mathesis, cursed by the church. Later, mathematics was "reinterpreted", in a theologically-correct way, using the myth of "Euclid" and his deductive proofs. The fact of the empirical proofs in the Elements, was, however, contrary to this myth. The discrepancy was resolved by Hilbert and Russell who rejected empirical proofs as unsound, reducing all mathematics to metaphysics. We explain why that formalist metaphysics is anti-utilitarian and culturally biased, not universal. Historically, most school-level math originated in the non-West with a practical epistemology, but was absorbed in the West after superimposing on it an incompatible Western metaphysics, still used to teach it. This has made mathematics needlessly complex. Accordingly, math can be made easy and more universal by reverting to a more practical epistemology.

description: Humans have a natural desire to keep a certain physical distance from other humans. This distance is called personal space (or personal distance). Edward T. Hall (1966) describes it as a distance of 45 to 120cm kept from each other, a which people can touch if they extend their arms and see each other clearly, but not asa whole. Humans always try to keep this minimum distance to strangers, but might let familiar people closer, depending on their relationship. If personal space isinvaded without consent it comes to physical reactions such as increased heart rate, sweating and increased blood pressure (Middlemist and Knowles, 1976). We simply feel uncomfortable when others come too close. Personal space is well described for standing and seated test subjects (e.g. Newman and Pollack, 1973; Thompson et al., 1979;Hayduk and Mainprize, 1980; Hayduk, 1981; Strube and Werner, 1984; Evans and Wener, 2007; Robson, 2008), but not for walking people. Gérin-Lajoie and his colleagues (Gérin-Lajoie et al., 2006; Gérin-Lajoie et al., 2008) described minimum distances that pedestrians keep from stationary and moving obstacles, which were used as a basis for this study. Using a newly developed system called CCB Analyser the walking patterns of pedestrians in an Austrian shopping center were recorded. Data included number and frequency of people,average speed, speed changes and number of speed changes, direction changes and number of direction changes, and two different measures for personal space, one being personal space in circles around stationary recording frames and the other being personal space for pedestrians that plan their paths ahead. The tested hypothesis was that high density and low interpersonal distance leads to a change of walking behavior – increasing walking speed because of stress (Kone?ni et al., 1975) and making people change their speed and directions whenwalking. The results of the present study show that all measured variables seem to highly depend on each other. We could at least partly confirm the hypothesis ofpeople walking faster when personal space is 51invaded. People changed their walking speed and direction to a higher degree at high densities, however the percentage of people changing their walking behavior was the same or even smaller. These results offer a first insight into the relationship of human walking behavior and personal space, but much more research needs to be done on this topic.
Geodesic motion in the vacuum C-metric

description: Geodesic equations of the vacuum C-metric are derived and solved for various cases. The solutions describe the motion of timelike or null particles with conserved energy and angular momentum. Polar, nearly-circular orbits around weakly accelerated black holes may be regarded as a perturbation of circular Schwarzschild geodesics. Results indicate that circular Schwarzschild geodesics of radius $r_0>6m$ are stable under small uniform accelerations along the orbital plane. These stable orbits undergo small oscillations around $r_0$, behaving like a harmonic oscillator driven by a periodic force plus another constant force. Circular orbits with axis parallel to the direction of black hole acceleration are also considered. In this case an algebraic relation expressing the condition of stability is obtained. This refines the stability analysis done in previous literature. We also present an analysis of radial geodesics along the poles. There exist a solution where a particle remains at unstable equilibrium at a fixed distance directly behind the accelerating black hole. Examples of numerical solutions are presented for other more general cases.

Effective Visualization and Analysis of Recommender Systems

subject: FOS: Computer and information sciences

description: Recommender system exists everywhere in the business world. From Goodreads to TikTok, customers of internet products become more addicted to the products thanks to the technology. Industrial practitioners focus on increasing the technical accuracy of recommender systems while at same time balancing other factors such as diversity and serendipity. In spite of the length of the research and development history of recommender systems, there has been little discussion on how to take advantage of visualization techniques to facilitate the algorithmic design of the technology. In this paper, we use a series of data analysis and visualization techniques such as Takens Embedding, Determinantal Point Process and Social Network Analysis to help people develop effective recommender systems by predicting intermediate computational cost and output performance. Our work is pioneering in the field, as to our limited knowledge, there have been few publications (if any) on visualization of recommender systems.
Predicting Crowd Behavior with Big Public Data

description: With public information becoming widely accessible and shared on today's web, greater insights are possible into crowd actions by citizens and non-state actors such as large protests and cyber activism. We present efforts to predict the occurrence, specific timeframe, and location of such actions before they occur based on public data collected from over 300,000 open content web sources in 7 languages, from all over the world, ranging from mainstream news to government publications to blogs and social media. Using natural language processing, event information is extracted from content such as type of event, what entities are involved and in what role, sentiment and tone, and the occurrence time range of the event discussed. Statements made on Twitter about a future date from the time of posting prove particularly indicative. We consider in particular the case of the 2013 Egyptian coup d'etat. The study validates and quantifies the common intuition that data on social media (beyond mainstream news sources) are able to predict major events.
Casimir energy for surfaces with constant conductivity

description: We consider the vacuum energy of the electromagnetic field in systems characterized by a constant conductivity using the zeta-regularization approach. The interaction in two cases is investigated: two infinitely thin parallel sheets and an infinitely thin spherical shell. We found that the Casimir energy for the planar system is always attractive and it has the same characteristic distance dependence as the interaction for two perfect semi-infinite metals. The Casimir energy for the spherical shell depends on the inverse radius of the sphere, but it maybe negative or positive depending on the value of the conductivity. If the conductivity is less than a certain critical value, the interaction is attractive, otherwise the Casimir force is repulsive regardless of the spherical shell radius.

description: Practical work is seen as having an important role in school science. In particular many have claimed that it has an essential role in determining students’ attitudes to school science and science beyond the classroom. However, whilst there has been much research into students’ attitudes to science there has been little research into their attitudes to practical work in particular. This study considers students’ attitudes in terms of the cognitive, affective and behavioural analytical framework developed by Rosenberg (1960). The study is based on data collected from three English secondary schools within Key Stages 3 and 4. It involved questionnaires in biology, chemistry and physics as well as school visits that involved lesson observations, semi-structured interviews and focus groups with students. Field notes and audio-recordings were made throughout these visits for subsequent analysis. The findings suggest that secondarystudents’ attitudes to practical work are, generally speaking, positive. However, what also emerged was the extent to which such attitudes to practical work differed, not only across the three sciences, but also showed a statistically significant decline as students progressed through their secondary school education. The reason for this being that therelative importance of the cognitive, affective and behavioural domains changed as students moved away from a focus on the enjoyment of science towards one that was examination orientated. The implications of this study suggests that teachers need to be far more aware that students’ attitudes to practical work need to be consider accordingto the science they are studying and their age, rather than seeing their attitudes to practical work being unchanging and uniform across the three sciences.
Teaching mathematics with a different philosophy. Part 2: Calculus without Limits

Publisher: name: arXiv

Subjects: subject: History and Overview (math.HO)

description: The example of the calculus is used to explain how simple, practical math was made enormously complex by imposing on it the Western religiously-colored notion of mathematics as "perfect". We describe a pedagogical experiment to make math easy by teaching "calculus without limits" using the new realistic philosophy of zeroism, different from Platonic idealism or formalist metaphysics. Despite its demonstrated advantages, it is being resisted because of the existing colonial hangover.

description: We study experimentally and theoretically the hydrodynamic interaction of pairs of circular inclusions in two-dimensional, fluid smectic membranes suspended in air. By analyzing their Brownian motion, we find that the radial mutual mobilities of identical inclusions are independent of their size but that the angular coupling becomes strongly size-dependent when their radius exceeds a characteristic hydrodynamic length. The observed dependence of the mutual mobilities on inclusion size is described well for arbitrary separations by a model that generalizes the Levine/MacKintosh theory of point-force response functions and uses a boundary-element approach to calculate the mobility matrix.
