description: The number of spanning trees in the giant component of the random graph $\G(n, c/n)$ ($c>1$) grows like $\exp\big\{m\big(f(c)+o(1)\big)\big\}$ as $n\to\infty$, where $m$ is the number of vertices in the giant component. The function $f$ is not known explicitly, but we show that it is strictly increasing and infinitely differentiable. Moreover, we give an explicit lower bound on $f'(c)$. A key lemma is the following. Let $\PGW(λ)$ denote a Galton-Watson tree having Poisson offspring distribution with parameter $λ$. Suppose that $λ^*>λ>1$. We show that $\PGW(λ^*)$ conditioned to survive forever stochastically dominates $\PGW(λ)$ conditioned to survive forever.

ARGUMENTAIRE TAXONOMIQUE
Hemihyalea mansueta aberration niger Seitz, 1925 est une entité infrasubspécifique décrite du Volcan Irazu au Costa Rica. Ce nom a été recombiné comme bonne espèce parToulgoët (1992 [1991]). En accord avec les articles 45.6.2 et 45.5.1 du Code International de Nomenclature Zoologique (ICZN, 1999), le nom niger doit ainsi être associé à Toulgoët (1992 [1991]). Plus tard, Toulgoët (1994) recombine niger comme une aberration de P. ochracea expliquant qu’après observation du type et de son armature génitale il s’agit d’une forme mélanisante très prononcée de P. ochracea. Cette recombinaison en entité infrasubpécifique est invalide au regard du Code. En revanche, nous sommes en accord avec le rapprochement effectué par Toulgoët (1994). Nous proposons donc cette synonymie.

description: Femtosecond electron bunches with complex temporal structures play a crucial role in THz generation, free-electron lasers and plasma wakefield accelerators. The ultrashort electron pulse duration can be reconstructed from the coherent transition radiation (CTR) spectrum based on prior knowledge. A weighted greedy sparse phase retrieval (WGESPAR) algorithm is developed to reduce the ambiguities for reconstructing the distribution of the beam current. This algorithm achieves better performance than iterative algorithms, especially for truncated noisy spectra of multibunch structures. Based on the WGESPAR algorithm, the complex temporal structures of femtosecond electron bunches generated from laser wakefield accelerators can be successfully reconstructed.

description: From a five-dimensional Einstein-Maxwell theory, Bah et al. constructed a singularity free topology star/black hole [Phys. Rev. Lett. 126, 151101 (2021)]. After the Klein-Kluza reduction, i.e., integrating the extra space dimension, it can obtain an effective four-dimensional static spherical charged black hole with scalar hair. In this paper, we study the quasinormal modes (QNMs) of the scalar field, electromagnetic field, and gravitational field on the background of this effective four-dimensional charged black hole. The radial parts of the perturbed fields all satisfy a Schrödinger-like equation. Using the asymptotic iteration method, we obtain the QNM frequencies semianalytically. For low overtone QNMs, the results obtained from the asymptotic iteration method and the Wentzel-Kramers-Brillouin approximation method agree well. In the null coordinates, the evolution of a Gaussian package is also studied. The QNM frequencies obtained by fitting the evolution data also agree well with the results obtained by the asymptotic iteration method.

Scheduling support for concurrency and parallelism in the Mach operating system

subject: FOS: Computer and information sciences

description: Abstract: "Changes in the use of multiprocessors are placing new demands on operating system schedulers. This article describes some of the new challenges posed by parallel and concurrent applications, and introduces techniques developed by the Mach project to meet these challenges. An overview of the techniques of timesharing scheduling and a description of the Mach scheduler are also included. This article describes work to incorporate processor allocation and control into the Mach operating system. The design approach divides the implementation into three components: (1) basic mechanisms implemented in the kernel, (2) long term policy implemented in a server, and (3) optional user implementation of short term policy.Isolating long-term policy in a server yields the advantages of policy-mechanism separation, while avoiding the drawbacks encountered in previous applications of this principle to multiprocessor scheduling. The design and implementation of a processor allocation server for a gang scheduling policy is also described. This article also describes work to support the effective multiprogrammed use of multiprocessors. The approach taken to this problem implements the scheduler in the kernel, but encourages users to provide hints. This allows the scheduler to take advantage of user knowledge without requiring users to implement sophisticated scheduling modules."

description: We show that strong-coupling (SC) of light and matter as it is realized with quantum dots (QDs) in microcavities differs substantially from the paradigm of atoms in optical cavities. The type of pumping used in semiconductors yields new criteria to achieve SC, with situations where the pump hinders, or on the contrary, favours it. We analyze one of the seminal experimental observation of SC of a QD in a pillar microcavity [Reithmaier et al., Nature (2004)] as an illustration of our main statements.
description: Substantially revised version. The major change is in the analysis of one of the seminal experiment of the field, that shows the excellent quantitative agreement with the theory. Full details, especially all concerning Fermi statistics (still present in previous versions), are now to be presented elsewhere. To be published in Phys. Rev. Lett. 101 (2008)

description: We consider the problem of the existence of a dynamical barrier of ``mass'' that needs to be excited on a lattice site to lead to the formation and subsequent persistence of localized modes for a nonlinear Schrodinger lattice. We contrast the existence of a dynamical barrier with its absence in the static theory of localized modes in one spatial dimension. We suggest an energetic criterion that provides a sufficient, but not necessary, condition on the amplitude of a single-site initial condition required to form a solitary wave. We show that this effect is not one-dimensional by considering its two-dimensional analog. The existence of a sufficient condition for the excitation of localized modes in the non-integrable, discrete, nonlinear Schrodinger equation is compared to the dynamics of excitations in the integrable, both discrete and continuum, version of the nonlinear Schrodinger equation.

description: We consider classical nonlinear oscillators on hexagonal lattices. When the coupling between the elements is repulsive, we observe coexisting states, each one with its own basin of attraction. These states differ by their degree of synchronization and by patterns of phase-locked motion. When disorder is introduced into the system by additive or multiplicative Gaussian noise, we observe a non-monotonic dependence of the degree of order in the system as a function of the noise intensity: intervals of noise intensity with low synchronization between the oscillators alternate with intervals where more oscillators are synchronized. In the latter case, noise induces a higher degree of order in the sense of a larger number of nearly coinciding phases. This order-by-disorder effect is reminiscent to the analogous phenomenon known from spin systems. Surprisingly, this non-monotonic evolution of the degree of order is found not only for a single interval of intermediate noise strength, but repeatedly as a function of increasing noise intensity. We observe noise-driven migration of oscillator phases in a rough potential landscape.

description: We consider the problem of scheduling jobs on a single machine with preemption, when the server is allowed to reject jobs at some penalty. We consider minimizing two objectives: total flow time and total job-idle time (the idle time of a job is the flow time minus the processing time). We give 2-competitive online algorithms for the two objectives and extend some of our results to the case of weighted flow time and machines with varying speeds. We also give a resource augmentation result for the case of arbitrary penalties achieving a competitive ratio of using a speed processor. Finally, we present a number of lower bounds for both the case of uniform and arbitrary penalties.

ARGUMENTAIRE TAXONOMIQUE
Toulgoët (1988) classe dans le groupe VI du genre Amastus Walker, 1855 les entités Hemihyalea vitripennis Hampson, 1920 et Phaegoptera alba Druce, 1884 décrites du Mexique. Or les Amastus sont très peu représentés en Amérique centrale, où l’on rencontre essentiellement le genre Pseudohemihyalea Rego Baros, 1956. À la suite du séquençage de spécimens des genres Amastus, Praeamastus Toulgoët, (1991 [1992]), Pseudohemihyalea et Pseudamastus Toulgoët, 1985 (cf. infra Amastus Walker, 1855), il apparaît clairement que les deux espèces ci-dessus sont sans conteste des Pseudohemihyalea. Il est intéressant d’ajouter que ces quatre genres forment des groupes bien distincts (variations entre 6,7 et 11,5 % entre les quatre genres) ce qui facilite grandement l’attribution générique des différents spécimens.Nous proposons donc ces recombinaisons.

description: With the exponential increase in the amount of digital information over the internet, online shops, online music, video and image libraries, search engines and recommendation system have become the most convenient ways to find relevant information within a short time. In the recent times, deep learning's advances have gained significant attention in the field of speech recognition, image processing and natural language processing. Meanwhile, several recent studies have shown the utility of deep learning in the area of recommendation systems and information retrieval as well. In this short review, we cover the recent advances made in the field of recommendation using various variants of deep learning technology. We organize the review in three parts: Collaborative system, Content based system and Hybrid system. The review also discusses the contribution of deep learning integrated recommendation systems into several application domains. The review concludes by discussion of the impact of deep learning in recommendation system in various domain and whether deep learning has shown any significant improvement over the conventional systems for recommendation. Finally, we also provide future directions of research which are possible based on the current state of use of deep learning in recommendation systems.

description: Numerous exact solutions to the nonlinear mean-field equations of motion are constructed for multicomponent Bose-Einstein condensates on one, two, and three dimensional optical lattices. We find both stationary and nonstationary solutions, which are given in closed form. Among these solutions are a vortex-anti-vortex array on the square optical lattice and modes in which two or more components slosh back and forth between neighboring potential wells. We obtain a variety of solutions for multicomponent condensates on the simple cubic lattice, including a solution in which one condensate is at rest and the other flows in a complex three-dimensional array of intersecting vortex lines. A number of physically important solutions are stable for a range of parameter values, as we show by direct numerical integration of the equations of motion.

description: We consider a quantum Bose fluid confined in a triple well potential in 1D within the exact N-body Bose-Hubbard model to investigate the phenomena of intrinsic decoherence and loss of purity. Our study is done by following the time evolution of one-body properties in an N-particle closed environment. We do an exhaustive exploration of initial conditions to characterize these phenomena. Here we illustrate our main findings with a set of relevant Fock and SU(3) coherent states. Our study shows that signatures of stationarity and maximal mixing are a direct consequence of the inter-particle interactions in the closed system and become evident as the number of particles is increased. This fact is confirmed by quantifying the deviations from stationarity by means of a matrix norm.

description: This paper presents Saharaline, an intervention designed to provide collective social support for teachers in low-income schools. Implemented as a WhatsApp-based helpline, Saharaline enables teachers to reach out for personalized, long-term assistance with a wide range of problems and stressors, including pedagogical, emotional, and technological challenges. Depending on the support needed, teachers' requests are routed to appropriate domain experts -- staff employed by educational non-profit organizations who understand teachers' on-the-ground realities -- who offer localized and contextualized assistance. Via a three-month exploratory deployment with 28 teachers in India, we show how Saharaline's design enabled a collective of diverse education experts to craft and deliver localized solutions that teachers could incorporate into their practice. We conclude by reflecting on the efficacy of our intervention in low-resource work contexts and provide recommendations to enhance collective social support interventions similar to Saharaline.

description: Abstract: "As the Internet grows in size, it becomes crucial to understand how the speeds of links in the network must improve in order to sustain the pressure of new end-nodes being added each day. Although the speeds of links in the core and at the edges roughly improve according to Moore's law, this improvement alone might not be enough. Indeed, the structure of the Internet graph and routing in the network might necessitate much faster improvements in the speeds of key links in the network. In this paper, using a combination of analysis and extensive simulations, we show that the worst congestion in the Internet in fact scales poorly with the network size (n[superscript 1+[omega](1)], where n is the number of nodes), when shortest-path routing is used. We also show, somewhat surprisingly, that policy-based routing does not exacerbate the maximum congestion when compared to shortest-path routing. Our results show that it is crucial to identify ways to alleviate this congestion to avoid some links from being perpetually congested. To this end, we show that the congestion scaling properties of the Internet graph can be improved dramatically by introducing moderate amounts of redundancy in the graph in terms of parallel edges between pairs of adjacent nodes."

description: We study the LHC signatures of TeV scale vectorlike quarks $b'$, $t'$ and $χ$ with electromagnetic charges -1/3, 2/3 and 5/3 that appear in many beyond the standard model (BSM) extensions. We consider warped extra-dimensional models and analyze the phenomenology of such vectorlike quarks that are the custodial partners of third generation quarks. In addition to the usually studied pair-production channels which depend on the strong coupling, we put equal emphasis on single production channels that depend on electroweak couplings and on electroweak symmetry breaking induced mixing effects between the heavy vectorlike quarks and standard model quarks. We identify new promising $gg$-initiated pair and single production channels and find the luminosity required for discovering these states at the LHC. For these channels, we propose a cut that allows one to extract the relevant electroweak couplings. Although the motivation is from warped models, we present many of our results model-independently.

description: We use the LAMOST spectra of member stars in Pleiades, M34, Praesepe, and Hyades to study how chromospheric activity vary as a function of mass and rotation at different age. We measured excess equivalent widths of H$α$, H$β$, and Ca~{\sc ii} K based on estimated chromospheric contributions from old and inactive field dwarfs, and excess luminosities are obtained by normalizing bolometric luminosity, for more than 700 late-type stars in these open clusters. Results indicate two activity sequences in cool spot coverage and H$α$ excess emission among GK dwarfs in Pleiades and M dwarfs in Praesepe and Hyades, paralleling with well known rotation sequences. A weak dependence of chromospheric emission on rotation exists among ultra fast rotators in saturated regime with Rossby number Ro$\lesssim0.1$. In the unsaturated regime, chromospheric and coronal emission show similar dependence on Ro, but with a shift toward larger Ro, indicating chromospheric emission gets easily saturated than coronal emission, and/or convective turnover time-scales based on X-ray data do not work well with chromospheric emission. More interestingly, our analysis show fully convective slow rotators obey the rotation-chromospheric activity relation similar to hotter stars, confirming the previous finding. We found correlations among H$α$, H$β$, and Ca~{\sc ii} K emissions, in which H$α$ losses are more important than Ca~{\sc ii} K for cooler and more active stars. In addition, a weak correlation is seen between chromospheric emission and photospheric activity that shows dependency on stellar spectral type and activity level, which provides some clues on how spot configuration vary as a function of mass and activity level.

Magnoptera watsoni Ruiz, 1989: 152, n. syn.
ARGUMENTAIRE TAXONOMIQUE
Elysius walkeri Rothschild, 1922 sont un genre et une espèce décrits simultanément à partir d’individus capturés des environs d’Arica, sur la côte pacifique du nord Chili. Un spécimen mâle et un spécimen femelle sont figurés dans la description originale, sur une planche en noir et blanc. Cependant, la définition de cette dernière rend malaisée la caractérisation de ce genre et de cette espèce qui sont depuis restés énigmatiques. Grâce à l’amabilité de l’auteur, V. H. R. Ruiz, des photographies couleur du couple figuré et conservé à IZUC nous ont été transmises. Après examen de ces photographies, il s’avère que le genre Magnoptera Ruiz, 1989 correspond au genre Amastus avec une envergure de plus de 60 mm, des ailes antérieures allongées et des postérieures blanches ainsi que des antennes fortement bipectinnées. De plus, l’espèce M.watsoni Ruiz, 1989 présente un habitus comparable à l’espèce A. walkeri (Rothschild, 1922) avec un thorax brun très velu et des ailes uniformement beige. Cette dernière espèce a été décrite sur un holotype mâle de Lima au Pérou, également sur la côte Pacifique, qui présente un milieu comparable à celui d’Arica. L’holotype est conservé au BMNH avec d’autres spécimens dont l’un (BM 2805), en provenance de Callao, banlieue de Lima, présente des genitalia mâles parfaitement identiques à ceux figurés par Ruiz (1989) sous le nom M. watsoni. Le genre Magnoptera est donc un synonyme du genre Amastus. L’espèce M. watsoni appartient au genre Amastus et est synonyme de A. walkeri. Nous proposons donc ces synonymies.

Intrinsic Spin Hall Effect Induced by Quantum Phase Transition in HgCdTe Quantum Wells

description: Spin Hall effect can be induced both by the extrinsic impurity scattering and by the intrinsic spin-orbit coupling in the electronic structure. The HgTe/CdTe quantum well has a quantum phase transition where the electronic structure changes from normal to inverted. We show that the intrinsic spin Hall effect of the conduction band vanishes on the normal side, while it is finite on the inverted side. This difference gives a direct mechanism to experimentally distinguish the intrinsic spin Hall effect from the extrinsic one.

description: Abstract: "Coarse coded memories have appeared in several neural network symbol processing models, such as Touretzky and Hinton's distributed connectionist production system DCPS, Touretzky's distributed implementation of Lisp S-expressions on a Boltzmann machine, and St. John and McClelland's PDP model of case role defaults. In order to determine how these models would scale, one must first have some understanding of the mathematics of coarse coded representations. For example, the working memory of DCPS, which stores triples of symbols and consists of 2,000 units, can hold roughly 20 items at a time out of a 15,625-symbol alphabet.How would DCPS scale if the alphabet size were raised to 50,000? With the current alphabet size, how many units would have to be added simply to double the working memory capacity to 40 triples? We present some analytical results related to these questions."

description: This paper explores the statistical relationship between natural images and their underlying range (depth) images. We look at how this relationship changes over scale, and how this information can be used to enhance low resolution range data using a full resolution intensity image. Based on our findings, we propose an extension to an existing technique known as shape recipes [3], and the success of the two methods are compared using images and laser scans of real scenes. Our extension is shown to provide a two-fold improvement over the current method. Furthermore, we demonstrate that ideal linear shape-from-shading filters, when learned from natural scenes, may derive even more strength from shadow cues than from the traditional linear-Lambertian shading cues.
Bethe ansatz description of edge-localization in the open-boundary XXZ spin chain

description: At large values of the anisotropy Δ, the open-boundary Heisenberg spin-1/2 chain has eigenstates displaying localization at the edges. We present a Bethe ansatz description of this `edge-locking' phenomenon in the entire Δ>1 region. We focus on the simplest spin sectors, namely the highly polarized sectors with only one or two overturned spins, i.e., one-particle and two-particle sectors. Edge-locking is associated with pure imaginary solutions of the Bethe equations, which are not commonly encountered in periodic chains. In the one-particle case, at large anisotropies there are two eigenstates with imaginary Bethe momenta, related to localization at the two edges. For any finite chain size, one of the two solutions become real as the anisotropy is lowered below a certain value. For two particles, a richer scenario is observed, with eigenstates having the possibility of both particles locked on the same or different edge, one locked and the other free, and both free either as single magnons or as bound composites corresponding to `string' solutions. For finite chains, some of the edge-locked spins get delocalized at certain values of the anisotropy (`exceptional points'), corresponding to imaginary solutions becoming real. We characterize these phenomena thoroughly by providing analytic expansions of the Bethe momenta for large chains, large anisotropy, and near the exceptional points. In the large-chain limit all the exceptional points coalesce at the isotropic point (Δ=1) and edge-locking becomes stable in the whole Δ>1 region.

description: The two reactions $γp\to K^+Λ$ and $π^-p\to K^0Λ$ are analyzed to determine the leading photoproduction multipoles and the pion-induced partial wave amplitudes in slices of the invariant mass. The multipoles and the partial-wave amplitudes are simultaneously fitted in a multichannel Laurent+Pietarinen model (L+P model), which determines the poles in the complex energy plane on the second Riemann sheet close to the physical axes. The results from the L+P fit are compared with the results of an energy-dependent fit based on the Bonn-Gatchina (BnGa) approach. The study confirms the existence of several poles due to nucleon resonances in the region at about 1.9\,GeV with quantum numbers $J^P = 1/2^+$, $3/2^+, 1/2^-, 3/2^-, 5/2^-$.

description: We propose a parameter server framework for distributed machine learning problems. Both data and workloads are distributed over worker nodes, while the server nodes maintain globally shared parameters, represented as dense or sparse vectors and matrices. The framework manages asynchronous data communication between nodes, and supports flexible consistency models, elastic scalability, and continuous fault tolerance. To demonstrate the scalability of the proposed framework, we show experimental results on petabytes of real data with billions of examples and parameters on problems ranging from Sparse Logistic Regression to Latent Dirichlet Allocation and Distributed Sketching.

ARGUMENTAIRE TAXONOMIQUE
Amastus thermidora forme peralta Seitz, 1925 est décrit de Monte Tolima en Colombie. Amastus thermidora Dognin, 1913 est décrit des environs de Loja en Équateur. Cette espèce sera mise en synonymie d’ A. ambrosia, décrite de Frontino en Colombie, parToulgoët (1988), le taxon peralta étant considéré comme une forme d’ A.ambrosia. Au regard de l’art. 45.6.4 du code de nomemclature le taxon peralta doit prendre le niveau de sous-espèce. La dénomination exacte aurait du être Amastus ambrosia peralta. L’observation d’un mâle syntype de peralta, localisé au SMF a montré que ce spécimen présente un habitus identique à l’holotype d’ A. ambrosia. Nous pensons qu’il s’agit d’un synonyme d’ A. ambrosia d’où la proposition ci-dessus.

description: We examine the problem of scalable file system directories, motivated by data-intensive applications requiring millions to billions of small files to be ingested in a single directory at rates of hundreds of thousands of file creates every second. We introduce a POSIX-compliant scalable directory design, GIGA+, that distributes directory entries over a cluster of server nodes. For scalability, each server makes only local, independent decisions about migration for load balancing. GIGA+ uses two internal implementation tenets, asynchrony and eventual consistency, to: (1) partition an index among all servers without synchronization or serialization, and (2) gracefully tolerate stale index state at the clients. Applications, however, are provided traditional strong synchronous consistency semantics. We have built and demonstrated that the GIGA+ approach scales better than existing distributed directory implementations, delivers a sustained throughput of more than 98,000 file creates per second on a 32-server cluster, and balances load more efficiently than consistent hashing.

description: In this paper, we investigate asymptotic properties of a consensus protocol taking place in a class of temporal (i.e., time-varying) networks called the activity driven network. We first show that a standard methodology provides us with an estimate of the convergence rate toward the consensus, in terms of the eigenvalues of a matrix whose computational cost grows exponentially fast in the number of nodes in the network. To overcome this difficulty, we then derive alternative bounds involving the eigenvalues of a matrix that is easy to compute. Our analysis covers the regimes of 1) sparse networks and 2) fast-switching networks. We numerically confirm our theoretical results by numerical simulations.
