description: The initial distribution of rotational velocities of stars is still poorly known, and how the stellar spin evolves from birth to the various end points of stellar evolution is an actively debated topic. Binary interactions are often invoked to explain the existence of extremely fast-rotating stars ($v\sin\,i$ $\gtrsim$ 200 $km\,s^{-1}$). The primary mechanisms through which binaries can spin up stars are tidal interactions, mass transfer, and possibly mergers. To evaluate these scenarios, we investigated in detail the evolution of three known fast-rotating stars in short-period spectroscopic and eclipsing binaries, namely HD 25631, HD 191495, and HD 46485, with primaries of masses of 7, 15, and 24 $M_{\odot}$, respectively, with companions of $\sim1\,M_\odot$ and orbital periods of less than 7 days. These systems belong to a recently identified class of binaries with extreme mass ratios, whose evolutionary origin is still poorly understood. We evaluated in detail three scenarios that could explain the fast rotation observed in these binaries: it could be primordial, a product of mass transfer, or the result of a merger within an originally triple system. We computed grids of single and binary MESA models varying tidal forces and initial binary architectures to investigate the evolution and reproduce observational properties of these systems. We find that, because of the extreme mass-ratio between binary components, tides have a limited impact, regardless of the prescription used, and that the observed short orbital periods are at odds with post-mass-transfer scenarios. The most likely scenario to form such young, rapidly rotating, and short-period binaries is primordial rotation, implying that the observed binaries are pre-interaction ones. These binaries show that the initial spin distribution of massive stars can have a wide range of rotational velocities.

description: In this paper we study spiderweb central configurations for the $N$-body problem, i.e configurations given by $N=n \times \ell+1$ masses located at the intersection points of $\ell$ concurrent equidistributed half-lines with $n$ circles and a central mass $m_0$, under the hypothesis that the $\ell$ masses on the $i$-th circle are equal to a positive constant $m_i$; we allow the particular case $m_0=0$. We focus on constructive proofs of the existence of spiderweb central configurations, which allow numerical implementation. Additionally, we prove the uniqueness of such central configurations when $\ell \in \{2,\dots,9\}$ and arbitrary $n$ and $m_i$; under the constraint $m_1\geq m_2\geq \ldots \geq m_n$ we also prove uniqueness for $\ell \in \{10,\dots,18\}$ and $n$ not too large. We also give an algorithm providing a rigorous proof of the existence and local unicity of such central configurations when given as input a choice of $n$, $\ell$ and $m_0, . . . ,m_n$. Finally, our numerical simulations highlight some interesting properties of the mass distribution.

description: The Pfaffian quantum Hall states, which can be viewed as involving pairing either of spin-polarized electrons or of composite fermions, are generalized by finding the exact ground states of certain Hamiltonians with k+1-body interactions, for all integers k > 0. The remarkably simple wavefunctions of these states involve clusters of k particles, and are related to correlators of parafermion currents in two-dimensional conformal field theory. The k=2 case is the Pfaffian. For k > 1, the quasiparticle excitations of these systems are expected to possess nonabelian statistics, like those of the Pfaffian. For k=3, these ground states have large overlaps with the ground states of the (2-body) Coulomb-interaction Hamiltonian for electrons in the first excited Landau level at total filling factors ν=2+3/5, 2+2/5.

description: Physical systems in the time domain may exhibit analogous phenomena in real space, such as time crystals, time-domain Fresnel lenses, and modulational interference in a qubit. Here we report the experimental realization of time-domain grating using a superconducting qutrit in periodically modulated probe and control fields via two schemes: Simultaneous modulation and complementary modulation. Both experimental and numerical results exhibit modulated Autler-Townes (AT) and modulation-induced diffraction (MID) effects. Theoretical results also confirm that the peak positions of the interference fringes of AT and MID effects are determined by the usual two-level relative phases, while the observed diffraction fringes, appearing only in the complementary modulation, are however related to the three-level relative phase. Further analysis indicates that such a single-atom time-domain diffraction originates from the correlation effect between the two time-domain gratings. Moreover, we find that the widths of the diffraction fringes are independent of the control-field power. Our results shed light on the experimental exploration of quantum coherence for modulated multi-level systems and may find promising applications in fast all-microwave switches and quantum-gate operations in the strong-driving regime.

description: We argue that type II string theories contain unstable NS4 branes, which descend from a conjectured unstable M4 brane of M-theory. Assuming that an M2 brane can arise in M5 brane/anti-brane annihilation, the unstable M4 brane, and also an unstable M3 brane, must exist as sphalerons. We compare the tensions of the unstable NS4 branes, M4 brane, and related type II unstable D-branes, and present 11d supergravity solutions for unstable Mp branes for all p. We study the Z_2 gauge symmetry on the worldvolume of unstable branes, and argue that it can never be unbroken in the presence of lower brane charge.

More precisely, we prove the following: Let $A= \left ( \begin{matrix} a & b \\ c & d \end{matrix} \right )$ be an arbitrary $2\times2$ matrix, $T=a+d$ its trace, $D= ad-bc$ its determinant and define \[ y_{n} :\,= \sum_{i=0}^{\lfloor n/2 \rfloor}\binom{n-i}{i}T^{n-2 i}(-D)^{i}. \] Then, for $n \geq 1$, \begin{equation*} A^{n}=\left ( \begin{matrix} y_{n}-d \,y_{n-1} & b \,y_{n-1} \\ c\, y_{n-1}& y_{n}-a\, y_{n-1} \end{matrix} \right ). \end{equation*} We use this formula together with an existing formula for the $n$-th power of a matrix, various matrix identities, formulae for the $n$-th power of particular matrices, etc, to derive various combinatorial identities.

We find, using organic compounds with known dissociation constants, that the spacing coefficient, 1+p, that characterizes the position of the n-th band as x_n ~ (1+p)^n, decreases with increasing dissociation constant, K_d. Theoretical arguments are developed to explain these experimental findings and to calculate explicitly the K_d dependence of 1+p.

An income-based approach to modeling commuting distance in the Toronto area

description: The purpose of this article is to propose a novel model of the effects of changes in shelter and driving costs on car commuting distances in the overheated Toronto housing market from 2011 to 2016. The model borrows from theoretical concepts of microeconomics and urban geography to examine the Toronto housing market. Using 2011 and 2016 Census data for census metropolitan areas (CMAs) and census agglomerations (CAs) in Southern Ontario and computed driving costs, the model of car commuting distance is based on variables of allocation of monthly household income to monthly shelter costs and driving costs as a function of the car driving distance to Toronto. Using this model, we can predict the effect on car commuting distance due to changes in any of the variables. The model also offers an explanation for communities of Toronto car commuters beyond a driving radius that we might expect for daily commuting. The model confirms that increases in shelter costs in the Toronto housing market from 2011 to 2016 have forced the boundaries of feasible housing locations outward, and forced households to move farther away, thus increasing car commuting distance.

description: Epoch based memory reclamation (EBR) is one of the most popular techniques for reclaiming memory in lock-free and optimistic locking data structures, due to its ease of use and good performance in practice. However, EBR is known to be sensitive to thread delays, which can result in performance degradation. Moreover, the exact mechanism for this performance degradation is not well understood. This paper illustrates this performance degradation in a popular data structure benchmark, and does a deep dive to uncover its root cause-a subtle interaction between EBR and state of the art memory allocators. In essence, modern allocators attempt to reduce the overhead of freeing by maintaining bounded thread caches of objects for local reuse, actually freeing them (a very high latency operation) only when thread caches become too large. EBR immediately bypasses these mechanisms whenever a particularly large batch of objects is freed, substantially increasing overheads and latencies. Beyond EBR, many memory reclamation algorithms, and data structures, that reclaim objects in large batches suffer similar deleterious interactions with popular allocators. We propose a simple algorithmic fix for such algorithms to amortize the freeing of large object batches over time, and apply this technique to ten existing memory reclamation algorithms, observing performance improvements for nine out of ten, and over 50% improvement for six out of ten in experiments on a high performance lock-free ABtree. We also present an extremely simple token passing variant of EBR and show that, with our fix, it performs 1.5-2.6x faster than the fastest known memory reclamation algorithm, and 1.2-1.5x faster than not reclaiming at all, on a 192 thread four socket Intel system.

Transverse waves in coronal flux tubes with thick boundaries: The effect of longitudinal flows
Creators: name: Soler, Roberto
Publisher: name: arXiv
Year: 2019
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Observations show that transverse magnetohydrodynamic (MHD) waves and flows are often simultaneously present in magnetic loops of the solar corona. The waves are resonantly damped in the Alfvén continuum because of plasma and/or magnetic field nonuniformity across the loop. The resonant damping is relevant in the context of coronal heating, since it provides a mechanism to cascade energy down to the dissipative scales. It has been theoretically shown that the presence of flow affects the waves propagation and damping, but most of the studies rely on the unjustified assumption that the transverse nonuniformity is confined to a boundary layer much thinner than the radius of the loop. Here we present a semi-analytic technique to explore the effect of flow on resonant MHD waves in coronal flux tubes with thick nonuniform boundaries. We extend a published method, which was originally developed for a static plasma, in order to incorporate the effect of flow. We allowed the flow velocity to continuously vary within the nonuniform boundary from the internal velocity to the external velocity. The analytic part of the method is based on expressing the wave perturbations in the thick nonuniform boundary of the loop as a Frobenius series that contains a singular term accounting for the Alfvén resonance, while the numerical part of the method consists of solving iteratively the transcendental dispersion relation together with the equation for the Alfvén resonance position. As an application of this method, we investigated the impact of flow on the phase velocity and resonant damping length of MHD kink waves. We consistently recover results in the thin boundary approximation obtained in previous studies. We have extended those results to the case of thick boundaries. We also explored the error associated with the use of the thin boundary approximation beyond its regime of applicability.

description: We investigate the influence of aperiodic modulations of the exchange interactions between nearest-neighbour rows on the phase transition of the two-dimensional eight-state Potts model. The systems are studied numerically through intensive Monte Carlo simulations using the Swendsen-Wang cluster algorithm for different aperiodic sequences. The transition point is located through duality relations, and the critical behaviour is investigated using FSS techniques at criticality. While the pure system exhibits a first-order transition, we show that the deterministic fluctuations resulting from the aperiodic coupling distribution are liable to modify drastically the physical properties in the neighbourhood of the transition point. For strong enough fluctuations of the sequence under consideration, a second-order phase transition is induced. The exponents $β/ν$, $γ/ν$ and $(1-α)/ν$ are obtained at the new fixed point and crossover effects are discussed. Surface properties are also studied.

description: The processes of energy gain and redistribution in a dense gas subject to an intense ultrashort laser pulse are investigated theoretically for the case of high-pressure argon. The electrons released via strong-field ionization and driven by oscillating laser field collide with neutral neighbor atoms, thus effecting the energy gain in the emerging electron gas via a short-range inverse Bremsstrahlung interaction. These collisions also cause excitation and impact ionization of the atoms thus reducing the electron-gas energy. A kinetic model of these competing processes is developed which predicts the prevalence of excited atoms over ionized atoms by the end of the laser pulse. The creation of a significant number of excited atoms during the pulse in high-pressure gases is consistent with the delayed ionization dynamics in the pulse wake, recently discovered by Gao et al.[1] This energy redistribution mechanism offers an approach to manage effectively the excitation vs. ionization patterns in dense gases interacting with intense laser pulses and thus opens new avenues for diagnostics and control in these settings.

description: Structured like an opera this PhD thesis sets the foundation for The School of Albino Feminist Thought & the School of Vitiligo Feminist Thought rendering the subject position of intersectionality—being Black, being female—no longer relevant insofar as Black feminism neglected the Black female albino body in the first instance. My thesis names not one, but two branches of feminism and, in so doing, women of albinism and women of vitiligo become immutable. The thesis also brings forward the dark-skinned blue-eyed girl child to deconstruct the politics of Toni Morrison’s The Bluest Eye and make it necessary to always ask what does a Black woman look like in “theory and practice.” In short, I explain that although albinism and vitiligo are not “races” they can be found among all racialized bodies — including “White people” — and while the majority of White people do not have blue eyes, in the White imaginary such eyes signify purity and a form of beauty the Black subject, especially the dark-skinned Black subject, will never possess. The pervasive belief system little Black girls with blue eyes do not exist corrupts the evolution of African-American consciousness and the trajectory of feminism. My research and theoretical frameworks disempower the history of Black feminisms for rebirth by turning the agency human cognition applies to the flesh and eye color against itself and, effectively, demonstrates the true positionality of Blackness, for example, embodies the power to transform racial consciousness and the very notion of white skin privilege/White fragility too. Thus, the primary research question at the emergence of the albino girl child from the womb becomes an academic mainstay: “Who holds dominion over whiteness?”

The propagators fall off like $1/k^2$ and the Lagrangean is polynomial but it is not powercounting renormalizable due to derivative couplings.

description: Recently, a new class of carbon allotrope called protomene was proposed. This new structure is composed of sp2 and sp3 carbon-bonds. Topologically, protomene can be considered as an sp3 carbon structure (~80% of this bond type) doped by sp2 carbons. First-principles simulations have shown that protomene presents an electronic bandgap of ~3.4 eV. However, up to now, its mechanical properties have not been investigated. In this work, we have investigated protomene mechanical behavior under tensile strain through fully atomistic reactive molecular dynamics simulations using the ReaxFF force field, as available in the LAMMPS code. At room temperature, our results show that the protomene is very stable and the obtained ultimate strength and ultimate stress indicates an anisotropic behavior. The highest ultimate strength was obtained for the x-direction, with a value of ~110 GPa. As for the ultimate strain, the highest one was for the z-direction (~25% of strain) before protomene mechanical fracture.

description: Social media platforms prevent malicious activities by detecting harmful content of posts and comments. To that end, they employ large-scale deep neural network language models for sentiment analysis and content understanding. Some models, like BERT, are complex, and have numerous parameters, which makes them expensive to operate and maintain. To overcome these deficiencies, industry experts employ a knowledge distillation compression technique, where a distilled model is trained to reproduce the classification behavior of the original model. The distillation processes terminates when the distillation loss function reaches the stopping criteria. This function is mainly designed to ensure that the original and the distilled models exhibit alike classification behaviors. However, besides classification accuracy, there are additional properties of the original model that the distilled model should preserve to be considered as an appropriate abstraction. In this work, we explore whether distilled TinyBERT models preserve confidence values of the original BERT models, and investigate how this confidence preservation property could guide tuning hyperparameters of the distillation process.

Biutiful: reflexiones sobre estéticas políticas de lo extranjero y de lo otro en el cine contemporáneo
Creators: name: Bongers, Wolfgang

description: Biutiful (Alejandro González Iñárritu, 2010) propone una estética sombría de la deformación, de lo extraño y lo extranjero en la construcción de los personajes, las imágenes y el relato sobre el protagonista Uxbal y los inmigrantes chinos y africanos en Barcelona, que contrasta con la Barcelona resplandeciente e inverosímil de Vicky Cristina Barcelona (Woody Allen, 2008). El artículo analiza estas y otras películas, sintomáticas de las masivas incertidumbres identitarias y precariedades del capitalismo mundial integrado (Guattari). Biutiful (Alejandro González Iñárritu, 2010) proposes a dark aesthetics of deformation, of the weird and the strange in the construction of the characters, the images and the story about protagonist Uxbal and the Chinese and African immigrants in Barcelona, that contrast with a radiant and improbable Barcelona in Vicky Cristina Barcelona (Woody Allen, 2008). This article analyzes these and other movies as symptomatic of the massive identitarian uncertainties and precariousness of integrated global capitalism (Guattari).

description: The present work deals with dynamical system analysis of a Quintom Model of Dark Energy. By suitable transformation of variables the Einstein field equations are converted to an autonomous system. The critical points are determined and stability of hyperbolic critical points are determined by Hartman-Grobman theorem. To analyze non-hyperbolic critical points different tools (notably Center Manifold theory) are used. Possible bifurcation scenarios have also been explained.

description: Tomando como ejemplo las películas de Icíar Bollaín, Isabel Coixet y Tania Hermida, se analizan diferentes estéticas transnacionales del cine contemporáneo en el contexto del desarrollo de las culturas cinematográficas. Los resultados se comparan con las críticas sobre las películas para hacer un balance entre el deseo de identificación a nivel nacional y los retos del cine arte que se dirige a diferentes culturas e intenta cambiar los hábitos de percepción. Considering the films of Icíar Bollaín, Isabel Coixet and Tania Hermida, diffe-rent approaches to transnational aesthetics in contemporary cinema are shown and related to their context of developing cinema cultures. The results are compared with film critiques by evaluating their notions of identity and national cinema. The final discussion is about the aims of arthouse cinema in different cultures and its tendency to change the habits of perception.

“Extranjeros en tiempos revueltos”: figuras de lo extraño/extranjero en la telenovela Amar en tiempos revueltos
Creators: name: Genschow, Karen
Publisher: name: Estudios Culturales Hispánicos
Year: 2021

description: El artículo propone una lectura de la telenovela española Amar en tiempos revueltos a partir de las figuras “extranjeras” que aparecen a lo largo de las primeras tres temporadas. Estas vienen a “revolver” de diferentes maneras la sociedad franquista de posguerra, articulando conflictos socio-históricos en la trama, pero remitiendo también a problemas actuales. El marco conceptual está conformado por el género –“extranjero asimilado” a su vez en España– que con su código narrativo particular estructura los con-flictos y sus soluciones. The article analyses the “foreign” characters that appear throughout the first three seasons of the Spanish telenovela Amar en tiempos revueltos. These characters come to “stir” the Francoist post-war society in different ways, articulating socio-historical conflicts in the plot, but also referring to current problems. The conceptual framework is shaped by the genre itself – an “assimilated foreigner” in Spain – which, with its particular narrative code, structures the conflicts and their solutions.

Loschmidt echo of local dynamical processes in integrable and non integrable spin chains

description: The Loschmidt echo is investigated to track the effect of the local QDP. It is also quite sensitive to whether the background dynamics is integrable or not. For the integrable case, viz. the Heisenberg model, the Loschmidt echo depends on the parameters operators corresponding to the QDP as well as the time of QDP. The probability of reviving the system to its initial state is higher for incoherent QDPs occurring at large time intervals. Whereas each time coherent QDP occurs certain probability of reviving the state is always lost. For For the non-integrable case, viz. a kicked Harper model, it exhibits a decaying behaviour when contrasted with integrable dynamics. The decay rate is slower when the corresponding classical Hamiltonian is non chaotic. The Loschmidt echo also distinguishes the integrable and the nonintegrable dynamics when a QDP occurs.
