Transient Random Walks in Random Environment on a Galton-Watson Tree
Creators: name: Aidekon, Elie
Publisher: name: arXiv

Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: We consider a transient random walk $(X_n)$ in random environment on a Galton--Watson tree. Under fairly general assumptions, we give a sharp and explicit criterion for the asymptotic speed to be positive. As a consequence, situations with zero speed are revealed to occur. In such cases, we prove that $X_n$ is of order of magnitude $n^Λ$, with $Λ\in (0,1)$. We also show that the linearly edge reinforced random walk on a regular tree always has a positive asymptotic speed, which improves a recent result of Collevecchio \cite{Col06}.

description: This article examines the artefacts of big game hunting in male elephants from East Africa, natural history collections of the late nineteenth and early twentieth centuries. A contextual object biography approach is utilized to analyse the life histories of these specimens through the use of archival and isotopic evidence. Emphasis is placed on the example of an elephant shot on Mt Elgon, Kenya, in 1902, parts of which were preserved and shipped to England for curation and display in the Powell-Cotton Museum in Kent. The results of isotopic analyses on some of the remains reveal a life history that has implications for developing conservation strategies for modern elephant populations in the region and contribute baseline data critical for interpreting the isotopic signatures of ancient ivory believed to have been exported from eastern Africa.

Coverage processes on spheres and condition numbers for linear programming

description: This paper has two agendas. Firstly, we exhibit new results for coverage processes. Let $p(n,m,α)$ be the probability that $n$ spherical caps of angular radius $α$ in $S^m$ do not cover the whole sphere $S^m$. We give an exact formula for $p(n,m,α)$ in the case $α\in[π/2,π]$ and an upper bound for $p(n,m,α)$ in the case $α\in [0,π/2]$ which tends to $p(n,m,π/2)$ when $α\toπ/2$. In the case $α\in[0,π/2]$ this yields upper bounds for the expected number of spherical caps of radius $α$ that are needed to cover $S^m$. Secondly, we study the condition number ${\mathscr{C}}(A)$ of the linear programming feasibility problem $\exists x\in\mathbb{R}^{m+1}Ax\le0,x\ne0$ where $A\in\mathbb{R}^{n\times(m+1)}$ is randomly chosen according to the standard normal distribution. We exactly determine the distribution of ${\mathscr{C}}(A)$ conditioned to $A$ being feasible and provide an upper bound on the distribution function in the infeasible case. Using these results, we show that $\mathbf{E}(\ln{\mathscr{C}}(A))\le2\ln(m+1)+3.31$ for all $n>m$, the sharpest bound for this expectancy as of today. Both agendas are related through a result which translates between coverage and condition.

description: We show that the motivic spectrum representing algebraic $K$-theory is a localization of the suspension spectrum of $\mathbb{P}^\infty$, and similarly that the motivic spectrum representing periodic algebraic cobordism is a localization of the suspension spectrum of $BGL$. In particular, working over $\mathbb{C}$ and passing to spaces of $\mathbb{C}$-valued points, we obtain new proofs of the topological versions of these theorems, originally due to the second author. We conclude with a couple of applications: first, we give a short proof of the motivic Conner-Floyd theorem, and second, we show that algebraic $K$-theory and periodic algebraic cobordism are $E_\infty$ motivic spectra.

Efficient timing jitter simulation for passively mode-locked semiconductor lasers

Publisher: name: arXiv
Year: 2024
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: Efficient simulation of the timing jitter in passively mode-locking lasers is key to their numerical investigation and optimization. We introduce a method based on the pulse-period fluctuation auto-correlation function and compare it against established methods with respect to their estimate error. Potential improvements of the computational cost by about two orders of magnitude are reported. This advantage may facilitate larger parameter studies of passively mode-locked laser on small scale clusters or even desktop computers and thereby guide the target-oriented design of future lasers with ultra low timing jitter.

We derive an initial value problem for a first order differential equation whose solution $α(x)$ characterizes the limit behavior of $a_{ν,k}$ in the following sense: $$ \lim_{k \to \infty} \frac{a_{kx,k}}{k} = α(x), \quad x \geq 0. $$ Moreover, we show that $$ a_{ν,k} < \frac{πk}{R-1} + \frac{πν}{2R}. $$ We use $α(x)$ to obtain an explicit expression of the Pleijel constant for planar annuli and compute some of its values.

description: We derive an asymptotic formula for the amplitude distribution in a fully nonlinear shallow-water solitary wave train which is formed as the long-time outcome of the initial-value problem for the Su-Gardner (or one-dimensional Green-Naghdi) system. Our analysis is based on the properties of the characteristics of the associated Whitham modulation system which describes an intermediate "undular bore" stage of the evolution. The resulting formula represents a "non-integrable" analogue of the well-known semi-classical distribution for the Korteweg-de Vries equation, which is usually obtained through the inverse scattering transform. Our analytical results are shown to agree with the results of direct numerical simulations of the Su-Gardner system. Our analysis can be generalised to other weakly dispersive, fully nonlinear systems which are not necessarily completely integrable.

description: The field of probabilistic logic programming (PLP) focuses on integrating probabilistic models into programming languages based on logic. Over the past 30 years, numerous languages and frameworks have been developed for modeling, inference and learning in probabilistic logic programs. While originally PLP focused on discrete probability, more recent approaches have incorporated continuous distributions as well as neural networks, effectively yielding neural-symbolic methods. We provide a unified algebraic perspective on PLP, showing that many if not most of the extensions of PLP can be cast within a common algebraic logic programming framework, in which facts are labeled with elements of a semiring and disjunction and conjunction are replaced by addition and multiplication. This does not only hold for the PLP variations itself but also for the underlying execution mechanism that is based on (algebraic) model counting.

description: We present exact numerical data for the lowest-energy momentum eigenstates (yrast states) of a repulsive spin impurity in a one-dimensional Bose gas using full configuration interaction quantum Monte Carlo (FCIQMC). As a stochastic extension to exact diagonalization it is well suited for the study of yrast states of a lattice-renormalized model for a quantum gas. Yrast states carry valuable information about the dynamic properties of slow-moving mobile impurities immersed in a many-body system. Based on the energies and the first and second order correlation functions of yrast states, we identify different dynamical regimes and the transitions between them: The polaron regime, where the impurity's motion is affected by the Bose gas through a renormalized effective mass; a regime of a gray soliton that is weakly correlated with a stationary impurity, and the depleton regime, where the impurity occupies a dark or gray soliton. Extracting the depleton effective mass reveals a super heavy regime where the magnitude of the (negative) depleton mass exceeds the mass of the finite Bose gas.

description: Most stars form in dense star clusters deeply embedded in residual gas. These objects must therefore be seen as the fundamental building blocks of galaxies. With this contribution some physical processes that act in the very early and also later dynamical evolution of dense stellar systems in terms of shaping their later appearance and properties, and the impact they have on their host galaxies, are highlighted. Considering dense systems with increasing mass, it turns out that near 10^6 Msol their properties change fundamentally: stellar populations become complex, a galaxial mass--radius relation emerges and the median two-body relaxation time becomes longer than a Hubble time. Intriguingly, only systems with a two-body relaxation time longer than a Hubble time show weak evidence for dark matter, whereby dSph galaxies form total outliers.

description: A multicolour ECL system consisting of a conjugate composed of BODIPY (boron-dipyrromethene) core coupled via an amide linkage to DOTA (1,4,7,10-Tetraazacyclododecane-1,4,7-tris(t‑butyl acetate)) was studied. When a lanthanide ion was bound to the DOTA ligand, it was found that energy transfer could be initiated by optical but not electrochemical excitation. However, ECL experiments on the conjugate in the absence of lanthanide ions, revealed an interesting dual wavelength ECL behaviour at 549 and 730 nm in both annihilation and co-reactant pathways, which could be modulated by controlling the potential. Using the 3D ECL technique to probe the potential and concentration dependence of the ECL emission, it was possible to characterise the various mechanisms giving rise to annihilation and co-reactant ECL emissions in the visible and near-infrared. Analysis of the energetics of each reaction showed that aggregation following radical ion electrogeneration explained the long wavelength emission, facilitated by the incorporation of tBu-DO3A into the BODIPY structure. This system offers interesting new insights into BODIPY-based ECL systems.

description: We present a detailed comparison of the CO (3-2) emitting molecular gas between a local sample of luminous infrared galaxies (U/LIRGs) and a high-redshift sample that comprises submm selected galaxies (SMGs), quasars, and Lyman Break Galaxies (LBGs). The U/LIRG sample consists of our recent CO (3-2) survey using the Submillimeter Array while the CO (3-2) data for the high-redshift population are obtained from the literature. We find that the and L FIR relation is correlated over five orders of magnitude, which suggests that the molecular gas traced in CO (3-2) emission is a robust tracer of dusty star formation activity. The near unity slope of 0.93 ± 0.03 obtained from a fit to this relation suggests that the star formation efficiency is constant to within a factor of 2 across different types of galaxies residing in vastly different epochs. The CO (3-2) size measurements suggest that the molecular gas disks in local U/LIRGs (0.3-3.1 kpc) are much more compact than the SMGs (3-16 kpc), and that the size scales of SMGs are comparable to the nuclear separation (5-40 kpc) of the widely separated nuclei of U/LIRGs in our sample. We argue from these results that the SMGs studied here are predominantly intermediate stage mergers, and that the wider line widths arise from the violent merger of two massive gas-rich galaxies taking place deep in a massive halo potential.

description: Let $L$ be a fixed branch -- that is, an irreducible germ of curve -- on a normal surface singularity $X$. If $A,B$ are two other branches, define $u_L(A,B) := \dfrac{(L \cdot A) \: (L \cdot B)}{A \cdot B}$, where $A \cdot B$ denotes the intersection number of $A$ and $B$. Call $X$ arborescent if all the dual graphs of its resolutions are trees. In a previous paper, the first three authors extended a 1985 theorem of Płoski by proving that whenever $X$ is arborescent, the function $u_L$ is an ultrametric on the set of branches on $X$ different from $L$. In the present paper we prove that, conversely, if $u_L$ is an ultrametric, then $X$ is arborescent. We also show that for any normal surface singularity, one may find arbitrarily large sets of branches on $X$, characterized uniquely in terms of the topology of the resolutions of their sum, in restriction to which $u_L$ is still an ultrametric. Moreover, we describe the associated tree in terms of the dual graphs of such resolutions. Then we extend our setting by allowing $L$ to be an arbitrary semivaluation on $X$ and by defining $u_L$ on a suitable space of semivaluations. We prove that any such function is again an ultrametric if and only if $X$ is arborescent, and without any restriction on $X$ we exhibit special subspaces of the space of semivaluations in restriction to which $u_L$ is still an ultrametric.

description: By combining interface-sensitive non-linear magneto-optical experiments with femtosecond time resolution and ab-initio time-dependent density functional theory, we show that optically excited spin dynamics at Co/Cu(001) interfaces proceeds via spin-dependent charge transfer and backtransfer between Co and Cu. This ultrafast spin transfer competes with dissipation of spin angular momentum mediated by spin-orbit coupling already on sub 100 fs timescales. We thereby identify the fundamental microscopic processes during laser-induced spin transfer at a model interface for technologically relevant ferromagnetic heterostructures.

It is found to be comparable to A_N(s) for pp scattering, but of the opposite sign. It seems that this method could be a practical for measuring the polarization of a He3 beam.

title: Navigating school development and children’s rights governance in resource-poor contexts in Karnataka, India
Creators: name: Ipe, Rebecca
Publisher: name: University of Glasgow
Year: 2021

description: How do participants in school governance govern rights-based policies to education? In north Karnataka, India, School Development and Management Committees (SDMCs) are legal governance bodies where marginalised, resource-poor citizens can govern school affairs and enact school development goals. India’s 2009 Right to Education not only focuses on development goals, but also emphasises a rights-based approach that implicates notions of childhood and discourses of children’s rights. Therefore, school governance is also bound up with governing the rights attached to the right to education. The dual nature of governance-its potential for emphasising structural inequality as well as its capacity for social empowerment- signify a middle ground, where perils coexist with promise. In this dissertation, I investigate the practice of school development and child rights governance in two government schools, one rural, one urban in Kalaburagi, north Karnataka. Taking a theoretical approach that fuses key developments in the studies of governance and childhood, I concentrate on eliciting narratives of the bottom-up practice of governance from resource poor parents, children, teachers, and activists. Designing a qualitative methodology to elicit these narratives, I relied on a variety of research methods: group and individual interviews, observations, fieldnotes, and arts-based interviews during two phases of research in the field spanning three months and two weeks in total. Through thematic analysis of prevalent patterns in participants’ accounts, I found that while governance demanded much effort and commitment from participants, they rationalised their efforts (and governance failures) through a discourse of care. Care for children was instrumental in helping participants navigate the middle ground of governance, preserve their motivation, and orient their practice.

description: We investigated the tunneling anisotropic magnetoresistance (TAMR) in thick hcp Co films at cryogenic temperatures using scanning tunneling microscopy. At around -350 mV, a strong TAMR up to 30\% is found with a characteristic voltage dependence and a reversal of sign. With the help of \textit{ab initio} calculations the TAMR can be traced back to a spin-polarized occupied surface states that experience a strong spin-orbit interaction leading to a magnetization direction depending hybridization with bulk states.
The spin expansion for binary black hole merger: new predictions and future directions

description: In a recent paper arXiv:0709.0299, we introduced a spin expansion that provides a simple yet powerful way to understand aspects of binary black hole (BBH) merger. This approach relies on the symmetry properties of initial and final quantities like the black hole mass m, kick velocity {\bf k}, and spin vector {\bf s}, rather than a detailed understanding of the merger dynamics. In this paper, we expand on this proposal, examine how well its predictions agree with current simulations, and discuss several future directions that would make it an even more valuable tool. The spin expansion yields many new predictions, including several exact results that may be useful for testing numerical codes. Some of these predictions have already been confirmed, while others await future simulations. We explain how a relatively small number of simulations -- 10 equal-mass simulations, and 16 unequal-mass simulations -- may be used to calibrate all of the coefficients in the spin expansion up to second order at the minimum computational cost. For a more general set of simulations of given covariance, we derive the minimum-variance unbiased estimators for the spin expansion coefficients. We discuss how this calibration would be interesting and fruitful for general relativity and astrophysics. Finally, we sketch the extension to eccentric orbits.

description: The local curvature of the space produced by the Sun causes not only the perihelion precession of Mercury's elliptical orbit, but also the variations of the whole orbit, in comparison with those predicted by the Newtonian theory of gravitation. Calculations show that the gravitational major-axis contraction of the Mercury's elliptical orbit is 1.3 kilometers which can be confirmed by the present astronomical distance measurement technology.

description: We present optical and X-ray data for the first object showing strong evidence for being a black hole in a globular cluster. We show the initial X-ray light curve and X-ray spectrum which led to the discovery that this is an extremely bright, highly variable source, and thus must be a black hole. We present the optical spectrum which unambiguously identifies the optical counterpart as a globular cluster, and which shows a strong, broad [O III] emission line, most likely coming from an outflow driven by the accreting source.

description: In an effort to encourage self-regulation of the astronomy job market, I examine the supply of, and demand for, astronomers over time. On the supply side, I document the production rate of Ph.D. astronomers from 1970 to 2006 using the UMI Dissertation Abstracts database, along with data from other independent sources. I compare the long-term trends in Ph.D. production with federal astronomy research funding over the same time period, and I demonstrate that additional funding is correlated with higher subsequent Ph.D. production. On the demand side, I monitor the changing patterns of employment using statistics about the number and types of jobs advertised in the AAS Job Register from 1984 to 2006. Finally, I assess the sustainability of the job market by normalizing this demand by the annual Ph.D. production. The most recent data suggest that there are now annual advertisements for about one postdoctoral job, half a faculty job, and half a research/support position for every new domestic Ph.D. recipient in astronomy and astrophysics. The average new astronomer might expect to hold up to 3 jobs before finding a steady position.

description: Combining data from the ACS Virgo Cluster Survey (ACSVCS) and the Next Generation Virgo cluster Survey (NGVS), we extend previous studies of color gradients of the globular cluster (GC) systems of the two most massive galaxies in the Virgo cluster, M87 and M49, to radii of $\sim 15~R_e$ ($\sim 200$ kpc for M87 and $\sim 250$ kpc for M49). We find significant negative color gradients, i.e., becoming bluer with increasing distance, out to these large radii. The gradients are driven mainly by the outwards decrease of the ratio of red to blue GC numbers. The color gradients are also detected out to $\sim 15~R_e$ in the red and blue sub-populations of GCs taken separately. In addition, we find a negative color gradient when we consider the satellite low-mass elliptical galaxies as a system, i.e., the satellite galaxies closer to the center of the host galaxy usually have redder color indices, both for their stars and GCs. According to the "two phase" formation scenario of massive early-type galaxies, the host galaxy accretes stars and GCs from low-mass satellite galaxies in the second phase. So the accreted GC system naturally inherits the negative color gradient present in the satellite population. This can explain why the color gradient of the GC system can still be observed at large radii after multiple minor mergers.

description: Within VISION project short-term staff exchanges of senior scientists and Principal investigators (PI) of up to 5 days from the different multidisciplinary teams participating in the project’s consortium were planned. These exchanges are expected to promote and strengthen collaborations in the field of GI cancer and application of smart nanomaterials into biomedicine so that the diagnosis and treatment of cancer, including the biosafety of these nanomaterials at bilateral level will be improved. During these visits, specific topics can be discussed and it will provide an opportunity for the different PIs to visit the facilities of all consortium members in order to brainstorm, create and develop ideas for new research projects and strategies.
Electron spin relaxation via flexural phonon modes in semiconducting carbon nanotubes

description: This work considers the g-tensor anisotropy induced by the flexural thermal vibrations in one-dimensional structures and its role in electron spin relaxation. In particular, the mechanism of spin-lattice relaxation via flexural modes is studied theoretically for localized and delocalized electronic states in semiconducting carbon nanotubes in the presence of magnetic field. The calculation of one-phonon spin-flip process predicts distinctive dependencies of the relaxation rate on temperature, magnetic field and nanotube diameter. Comparison with the spin relaxation caused by the hyperfine interaction clearly suggests the relative efficiency of the proposed mechanism at sufficiently high temperatures. Specifically, the longitudinal spin relaxation time in the semiconducting carbon nanotubes is estimated to be as short as 30 microseconds at room temperature.

description: The underwater environment of Grotta Giusti (Monsummano Terme, Italy) is a suggestive setting with different types of speleothems including “leafy” and “cauliflower” concretions along the walls and roof, and conical pseudo-stalagmites on the floor. Very high calcium and dissolved CO2 levels, and massive calcium carbonate precipitation characterize this cave environment. Yet, life thrives on the leafy concretion surfaces with loads of cultivable heterotrophic microorganisms around 105 colony-forming units per cm2. Bacillus licheniformis appeared to be the prevalent cultivable microorganism on a low-nutrient medium that was used for screening. 16S rRNA gene-based polymerase chain reaction–single strand conformation polymorphism profiling indicated that Group VI Bacillaceae species was well represented in the bacterial community of underwater speleothems. Interpretation of X-ray diffraction spectra and Raman spectroscopy data indicated that the B. licheniformis isolate produced in vitro abundant calcite microcrystals that were also characterized by scanning electron microscopy coupled with energy dispersive X-ray spectroscopy. Production of calcite microcrystals was analyzed in different media (Christensen’s urea agar and B4 calcium carbonate precipitation medium) and incubation conditions, and it was found to be enhanced by nitrate supplement in B4 medium under low-oxygen conditions. B4 and B4-nitrate media also stimulated antibiotic production by the B. licheniformis isolate, which was analyzed by microbiological assays.

description: The vaginal immune system (VIS) is the first defense against antigens recognized as foreign. Substances capable of locally activating the VIS could be a valid strategy to treat vulvo-vaginal infections (VVI), caused by changes in the vaginal ecosystem, such as bacterial vaginosis (BV), vulvo-vaginal candidiasis (CA), and mixed vaginitis (MV). Bacterial lysates, obtained by crushing bacterial cultures, exert immuno-modulatory activities. The parietal fraction from Propionibacterium acnes is a patent of Depofarma (MoglianoVeneto, Italy). The preparation that associates such fraction to hyaluronic acid and polycarbophil is a registered trademark, commercially available in Italy as vaginal gel, Immunovag®. The study aimed to evaluate whether a 5-day-treatment with Immunovag® improves the symptoms and signs of VVI, in 60 women with Gardnerella vaginalis (GV), 154 with CA, 95 with MV, diagnosed with vulvar vaginal swab (VVS), and in 283 with BV, diagnosed with the Amsel criteria. At the end of the treatment (visit 2), the symptoms and signs of VVI disappeared in a significant number of subjects (χ2p vs pre-treatment) in all VVI groups, and their intensity was significantly (p ® represents a valid treatment of VVI induced by changes in the vaginal ecosystem.

description: We construct a cascading brane model of gravity in which the behavior of the gravitational force law interpolates from (n+4)-dimensional to (n+3)-dimensional all the way down to 4-dimensional from longer to shorter length scales. We show that at the linearized level, this model exhibits the features necessary for degravitation of the cosmological constant. The model is shown to be ghost free with the addition of suitable brane kinetic operators, and we demonstrate this using a number of independent procedures. Consequently this is a consistent IR modification of gravity, providing a promising framework for a dynamical, degravitating solution of the cosmological constant problem.

Detection of new eruptions in the Magellanic Clouds LBVs R 40 and R 110

description: We performed a spectroscopic and photometric analysis to study new eruptions in two luminous blue variables (LBVs) in the Magellanic Clouds. We detected a strong new eruption in the LBV R40 that reached $V \sim 9.2$ in 2016, which is around $1.3$ mag brighter than the minimum registered in 1985. During this new eruption, the star changed from an A-type to a late F-type spectrum. Based on photometric and spectroscopic empirical calibrations and synthetic spectral modeling, we determine that R\,40 reached $T_{\mathrm{eff}} = 5800-6300$~K during this new eruption. This object is thereby probably one of the coolest identified LBVs. We could also identify an enrichment of nitrogen and r- and s-process elements. We detected a weak eruption in the LBV R 110 with a maximum of $V \sim 9.9$ mag in 2011, that is, around $1.0$ mag brighter than in the quiescent phase. On the other hand, this new eruption is about $0.2$ mag fainter than the first eruption detected in 1990, but the temperature did not decrease below 8500 K. Spitzer spectra show indications of cool dust in the circumstellar environment of both stars, but no hot or warm dust was present, except by the probable presence of PAHs in R\,110. We also discuss a possible post-red supergiant nature for both stars.

description: [transcription] Monsieur,
Vous êtes bien bon d’avoir l’honnêteté de louer le travail d’un homme sans étude, sans lecture, sans secours ni talent, dont tout le mérite est d’avoir cherché à s’occuper et s’instruire. Tant de défauts m’ont empêché de donner au but ; mille choses dans tous les genres m’ont échappé, j’ai fait végéter des corps durs et pierreux, j’ai faconné les silex par le roulement des eaux de la mer, accordé aux molécules organiques la faculté de sentir de se mouvoir à volonté & c. Dans toutes ces conjectures, je n’ai suivi que les lumières de ma raison. L’observation et l’expérience donneront un grand avantage sur moi aux personnes qui auront vu; mais vous pouvez avoir remarqué, Monsieur, que je n’affirme rien, je doute et suis toujours prêt à abandonner mon sentiment quand il s’en présentera un plus plausible.
[fol. 128 v] Ces collections ont beaucoup plus augmenté depuis que j’en ai fini le catalogue, c’est un effet du bonheur que j’ai eu de rencontrer de bons amis qui se font un plaisir de me communiquer des pièces doubles, car la fortune d’un fermier général suffirait à peine pour rassembler tant de choses dans le peu de temps que mon frère et moi avons mis à former ce cabinet. Vos bienfaits, Monsieur, y tiennent une place distinguée et ce serait y mettre le comble, ainsi qu’à mes désirs que de venir nous éclairer sur une infinité de sujets et m’éclairer de vos lumières. Je n’ai point oublié que vous me l’avez promis plus d’une fois. J’attends l’exécution de cette promesse avec l’empressement de quelqu’un qui vous estime, vous honore et vous est dévoué plus que personne au monde. Vous trouverez ici une soupe, un lit et tout ce qui sera nécessaire pour votre commodité: vous y jouirez de la liberté que vous souhaiteriez. Je désire que ces offres vous déterminent et que vous soyez convaincu de la considération respectueuse avec laquelle je serai toute ma vie,

Monsieur,

Votre très humble et très obéissant serviteur.
