Perturbative and non-perturbative aspects of moments of the thrust distribution in e+e- annihilation

description: Resummation and power-corrections play a crucial role in the phenomenology of event-shape variables like the thrust T. Previous investigations showed that the perturbative contribution to the average thrust is dominated by gluons of small invariant mass, of the order of 10% of Q, where Q is the center-of-mass energy. The effect of soft gluons is also important, leading to a non-perturbative 1/Q correction. These conclusions are based on renormalon analysis in the single dressed gluon (SDG) approximation. Here we analyze higher moments of the thrust distribution using a similar technique. We find that the characteristic gluon invariant mass contributing to increases with m. Yet, for m=2 this scale is quite low, around 27% of Q, and therefore renormalon resummation is still very important. On the other hand, the power-correction to from a single soft gluon emission is found to be highly suppressed: it scales as 1/Q^3. In practice, and higher moments depend also on soft gluon emission from configurations of three hard partons, which may lead to alpha_s(Q^2)/Q power-corrections. This issue is yet to be investigated.

description: In the dynamical systems approach to describing turbulent or otherwise chaotic flows, an important quantity is the Lyapunov exponents and vectors that characterize the strange attractor of the flow. In particular, knowledge of the Lyapunov exponents and vectors will help identify perturbations that the system is most sensitive to, and quantify the dimension of the attractor. However, reliably computing these Lyapunov quantities requires robust nu- merical algorithms. While several perturbation-based techniques are available in literature, their application to commonly used turbulent flow solvers as well the numerical convergence properties have not been studied in detail. The goal of this work is two-fold: a) develop a robust algorithm for obtaining Lyapunov exponents and vectors for low-Mach based sim- ulation of turbulent flows, b) quantify the spatial and temporal convergence properties of this algorithm using a series of progressively complex flow problems. In particular, a manu- factured solutions approach is devised using the Orr-Sommerfeld (OS) perturbation theory to extract Lyapunov exponents and vectors from OS eigen solutions. While individual test cases show interesting results, overall the spatial convergence rates of Lyapunov exponents follow the truncation order for the discretization scheme. However, temporal convergence rates were found to be only a weak function of time step used. Additionally, for some config- urations, the convergence properties are found to depend on the Lyapunov exponent itself. These results indicate that convergence properties do not follow universal rates, and require careful analysis for specific configurations considered.

description: We study renormalizable nonlinear sigma-models in two dimensions with N=2 supersymmetry described in superspace in terms of chiral and complex linear superfields. The geometrical structure of the underlying manifold is investigated and the one-loop divergent contribution to the effective action is computed. The condition of vanishing beta-function allows to identify a class of models which satisfy this requirement and possess N=4 supersymmetry.

Microlensing of Quasars By Stars In Their Damped Lyman alpha Absorbers

Year: 1997
Subjects: subject: Astrophysics (astro-ph)

description: The damped Lyman alpha absorbers (DLAs) in quasar spectra are believed to be the progenitors of present-day disk galaxies. We examine the probability for microlensing of background quasars by stars in their DLAs. Microlensing by an individual star should magnify the continuum but not the broad emission lines of the quasars. Consequently, the equivalent width distribution of microlensed quasars would be distorted. We model a representative spiral galaxy as a closed system composed of a bulge, a disk, and a halo, and evolve the mass fraction of stars in the disk based on the observed metallicity of DLAs at high redshifts. The microlensing signatures are stronger if the halo of the galaxy is made of Massive Compact Halo Objects (MACHOs). In this case, the distortion imprinted by microlensing on the equivalent width distribution of quasar emission lines can be detected with high significance in a sample of about 10 DLAs with HI column densities N>10^21 cm^-2 and absorption redshifts z_abs<1. About a tenth of all quasars with DLAs (N>10^20 cm^-2) might show excess variability on timescales shorter than five years. A search for these signals would complement microlensing searches in local galaxies and calibrate the MACHO mass fraction in galactic halos at high redshifts.

description: The wheel-rail contact is known to cause material degradation in the forms of wear and rolling contact fatigue. Current maintenance techniques such as arc welding, rail grinding, and rail replacement contribute a significant portion of the operational cost. The large demand for a greater load-carrying capacity, particularly in Australia; a major producer of iron ore and coal, also necessitates an improvement in maintenance strategies. This research provides a systematic study towards developing a commercially viable railway maintenance technique using laser-cladding. This study has demonstrated that this technique is more cost-effective and prolongs the lives of rails and wheels.

Using the recent determination of the top quark mass, $m_t=(174 \pm 17)$ GeV, our best estimate is $\epp/\ep= 3.1 \pm 2.5 $, which lies in the range given by E731. We describe our determination of $\epp/\ep$ and make a comparison with other similar studies. A detailed discussion of the matching of the full theory to the effective Hamiltonian, written in terms of lattice operators, is also given.

description: We perform a detailed study of the production of isolated prompt photons in polarized hadronic collisions, in the centre-of-mass energy range relevant to RHIC. We compare the results obtained for a traditional cone-isolation prescription, with those obtained by imposing an isolation condition that eliminates any contribution to the cross section from the fragmentation mechanism. The latter prescription will allow us to present the first fully consistent next-to-leading order calculation in polarized prompt-photon production. We will discuss the theoretical uncertainties affecting the cross section, addressing the issue of the reliability of the perturbative expansion, for both inclusive isolated-photon and photon-plus-jet observables. Finally, we will study the dependence of our predictions upon the polarized parton densities, and the implications for the measurability of the gluon density.

description: Brownian motion whose infinitesimal variance changes according to a three-state continuous time Markov Chain is studied. This Markov Chain can be viewed as a telegraph process with one on state and two off states. We first derive the distribution of occupation time of the on state. Then the result is used to develop a likelihood estimation procedure when the stochastic process at hand is observed at discrete, possibly irregularly spaced time points. The likelihood function is evaluated with the forward algorithm in the general framework of hidden Markov models. The analytic results are confirmed with simulation studies. The estimation procedure is applied to analyze the position data from a mountain lion.

description: This systematic literature review (SLR) evaluates the impact of database and data warehouse technologies on organizational performance, with a particular focus on small and medium-sized enterprises (SMEs). By synthesizing 150 studies published between 2014 and 2024, this review highlights how these technologies improve customer satisfaction, operational efficiency, and competitive advantage. It explores the role of relational databases, NoSQL systems, and cloud computing in modern data management, while identifying gaps in research, such as the lack of focus on employee satisfaction and the underrepresentation of specific technologies like High-Performance Computing (HPC) and Customer Relationship Management (CRM) systems. The review also addresses the geographical bias in the literature, stressing the need for more research in developing regions. This SLR provides actionable insights for SMEs, policymakers, and IT professionals on how to leverage database technologies for enhanced business outcomes and long-term sustainability.

Et Nîmes doit payer ses bienfaits d'un autel (2).

(1) Feu M. de La Condamine disait avec raison aux académiciens ses confrères: M. Séguier n'a pas besoin de nous et nous avons tous besoin de lui.

(2) Par acte du 15 septembre 1778, M. Séguier a donné à l'académie de Nîmes son cabinet de livres, son cabinet d'antiques et le logement, pour en jouir après sa mort. Pendant qu'on passait l'acte, M. Séguier reçoit des lettres; des membres de l'académie, avec lesquels il se trouvait, le prient de les lire; il n'en veut rien faire par civilité; on signe l'acte; on remercie le bienfaiteur; on se retire. Alors, M. Séguier ouvre ses lettres et devinerait-on ce qu'il y trouve? Rien autre chose, sinon qu'on lui demande son cabinet pour le roi. Une action aussi généreuse porte sa louange avec elle.

description: The phase function of the dust coma of comet 67P has been determined from Rosetta/OSIRIS images \citep{Bertini17}. This function show a deep minimum at phase angles near 100$^\circ$, and a strong backscattering enhancement. These two properties cannot be reproduced by regular models of cometary dust, most of them based on wavelength-sized and randomly-oriented aggregate particles. We show, however, that an ensamble of oriented elongated particles of a wide variety of aspect ratios, with radii $r \gtrsim$10 $μ$m, and whose long axes are perpendicular to the direction of the solar radiation, are capable of reproducing the observed phase function. These particles must be absorbing, with an imaginary part of the refractive index of about 0.1 to match the expected geometric albedo, and with porosity in the 60-70\% range.

We describe how all these solutions are connected through the addition of a wave and/or monopoles. All solutions exhibit supersymmetry enhancement near the horizon. Furthermore we argue that string theory on these spaces is dual to specific superconformal field theories in two dimensions whose symmetry algebra in all cases contains the large N=4 algebra A_{gamma}. Implications for gauged supergravities are also discussed.

description: Children are the target of educational actions, both as passive subjects to whom conservation strategies are directed, and as active participants able to support operational management actions. Conservation actions driven by children can play an important role in critical social contexts where external (anthropogenic threats) and internal (organizational weaknesses) conditioning factors hinder effective protected areas management. In this article, we propose a case study where children involved in conservation practices offer operational support to overcome internal weaknesses of a park agency, motivate parks, staff and mitigate a series of anthropogenic threats. We used the “threat analysis” approach, derived by the Theory of Change, to define a causal chain linking ecosystem targets, human-induced threats, and conservation measures in a framework. We believe that conservation driven by children can be an innovative way to implement protected areas management in socially-degraded landscapes to the point of fostering local support for conservation.

description: La$_{1.5}$Ca$_{0.5}$CoIrO$_{6}$ is a re-entrant spin-glass (SG) that exhibits antiferromagnetic and ferromagnetic couplings at $T\sim95$ and $\sim86$ K, respectively, and at $T\sim25$ K a SG phase emerges. In this work we investigated the effect of hydrostatic pressure ($P$) on La$_{1.5}$Ca$_{0.5}$CoIrO$_{6}$ magnetic properties. By means of magnetization as a function of temperature measurements, carried under different applied pressures and/or magnetic fields, we have found that the freezing temperature of the SG phase exhibits an initial increase followed by a decrease with increasing $P$, and that the maximum $P$ = 7.9 kbar was not sufficient to prevent the formation of the frozen state. Since the ordering temperatures of the antiferromagnetic and ferromagnetic phases are also affected by $P$, we discuss the results here found in terms of changes on the balance between the magnetic phases.

description: We study how inflationary observables associated with primordial tensor modes are affected by coupling the minimal field content with an extra spin-2 particle during inflation. We work with a model that is ghost-free at the fully non-linear level and show how the new degrees of freedom modify standard consistency relations for the tensor bispectrum. The extra interacting spin-2 field is necessarily massive and unitarity dictates its mass be in the $m \gtrsim H$ range. Despite the fact that this bound selects a decaying solution for the corresponding tensor mode, cosmological correlators still carry the imprints of such "fossil" fields. Remarkably, fossil(s) of spin $\geq 1$ generate distinctive anisotropies in observables such as the tensor power spectrum. We show how this plays out in our set-up.

description: The production of vector bosons at present and future hadron colliders will provide a crucial test for QCD and Standard Model physics. In this paper we improve parton shower simulations of Drell-Yan processes by implementing matrix-element corrections to the initial-state radiation. We apply our work to the HERWIG Monte Carlo event generator and compare our phenomenological results with the ones obtained using the previous version of HERWIG, with resummed calculations which we match to the exact first-order perturbative result, and with recent Tevatron data. We also make some predictions for jet events at the LHC.

description: In the context of an Abelian gauge symmetry, spontaneously broken at a first-order transition, we discuss the evolution of the phase difference between the Higgs fields in colliding bubbles. We show that the effect of dissipation, represented by a finite plasma conductivity, is to cause the phases to equlibrate on a time-scale, determined by the conductivity, which can be much smaller than the bubble radii at the time of collision. Currents induced during the phase equilibration generate a magnetic flux, which is determined by the initial phase difference. In a three-bubble collision, the fluxes produced by each pair of bubbles combine, and a vortex can be formed. We find that, under most conditions, the probability of trapping magnetic flux to form a vortex is correctly given by the ``geodesic rule''.

description: We study Cooper pairing in the Dirac composite fermion (CF) system. The presence of the mass term in the Dirac CF description (which may simulate Landau level mixing) i.e. breaking of particle-hole (PH) symmetry in this system, is a necessary condition for the existence of a PH Pfaffian-like topological state. In the scope of RPA approximation and hydrodynamic approach, we find some signatures of pairing at finite frequencies. Motivated by this insight, we extend our analysis to the case of a different but still Dirac quasi-particle (CF) representation, appropriate in the presence of a mass term, and discuss the likelihood of PH Pfaffian pairing and Pfaffian pairing in general. On the basis of gauge field effects, we find for small Dirac mass anti-Pfaffian or Pfaffian instability depending on the sign of mass, while for large mass (Landau level mixing), irrespective of its sign, PH Pfaffian-like instability.

A Systematic Study on Modulation of Plasma Electrolytic Oxidation Parameters for Optimizing Photocatalytic Coatings on Titanium Substrates

subject: Water treatment processes

description: ABSTRACTIn this work, we investigated the preparation of porous titanium dioxide (TiO2) coatings via plasma electrolytic oxidation (PEO) for its use as a photocatalytic surface in water treatment. A fractional factorial design (FFD) was used to optimize various coating parameters such as electrolyte composition, electrical parameters, and treatment time. The impact of PEO parameters on the wettability, crystalline phase, and surface morphology of coatings was also investigated. The optimal PEO parameters were found to be the electrolyte composition (5 g.L-1 Na3PO4 and 4 g.L-1 KOH), electrical current density (6 A.dm-2), (80%) duty cycle, and (1000 Hz) frequency, as well as (10 min) treatment time. The photocatalytic behavior of the optimal coating was assessed under different experimental conditions, such as pollutant concentration, light intensity, and pH. The photocatalytic mechanism was proposed based on the results of Tauc plot, Mott–Schottky analysis, and scavenging experiments. Additionally, the efficiency of photocatalytic activation of peroxymonosulfate (PMS) by a PEO-treated TiO2 coating was evaluated for the first time. A synergistic effect between PMS and TiO2 was observed, and the total organic carbon (TOC) test showed notable mineralization at low [PMS]. The results suggest that this simple, environmentally-friendly, low-cost, and robust process is a promising coating method for the field of water treatment.
Scaling violations: Connections between elastic and inelastic hadron scattering in a geometrical approach

description: Starting from a short range expansion of the inelastic overlap function, capable of describing quite well the elastic pp and $\bar{p}p$ scattering data, we obtain extensions to the inelastic channel, through unitarity and an impact parameter approach. Based on geometrical arguments we infer some characteristics of the elementary hadronic process and this allows an excellent description of the inclusive multiplicity distributions in $pp$ and $\bar{p}p$ collisions. With this approach we quantitatively correlate the violations of both geometrical and KNO scaling in an analytical way. The physical picture from both channels is that the geometrical evolution of the hadronic constituents is principally reponsible for the energy dependence of the physical quantities rather than the dynamical (elementary) interaction itself.

description: Metropolitan residents are concerned about their exposure to airborne pollutants. But establishing these exposures is challenging. A compact personal exposure kit (PEK) was developed to evaluate personal integrated exposure (PIE) from time-resolved data to particulate matter with aerodynamic diameter less than 2.5 μm (PM2.5) in five microenvironments, including office, home, commuting, other indoor activities (other than home and office), and outdoor activities experienced both on weekdays and weekends. The study was conducted in Hong Kong. The PEK measured PM2.5, reported location and several other factors, stored collected data, as well as reported the data back to the investigators using global system for mobile communication (GSM) telemetry. Generally, PM2.5 concentrations in office microenvironment were found to be the smallest (13.0 μg/m3), whereas the largest PM2.5 concentration microenvironments were experienced during outdoor activities (54.4 μg/m3). Participants spent more than 85% of their time indoors, including in offices, homes, and other public indoor venues. On average, 42% and 81% of the time were spent in homes, which contributed 52% and 79% of PIE (during weekdays and weekends, respectively), suggesting that improvement of air quality in homes may reduce overall exposures and indicating the need for actions to mitigate possible public health burdens in Hong Kong. This study also found that various indoor/outdoor microenvironments experienced by urban office workers cannot be accurately represented by general urban air quality data reported from the regulatory monitoring. Such personalized air quality information, especially while in transit or in offices and homes, may provide improved information on population exposures to air pollution. Implications: A newly developed personal exposure kit (PEK) was used to monitor PM2.5 exposure of metropolitan citizens in their daily life. Different microenvironments and time durations caused various personal integrated exposure (PIE). The stationary monitoring method for PIE was also compared and evaluated with PEK. Positive protection actions can be taken after understanding the major contribution to PM2.5 exposure.

description: [transcription] À Paris, le 28 de mai 1761.
Je ne dois pas différer plus longtemps, Monsieur, à vous faire mille et millejustes remerciements pour toutes les peines que vous voulez bien prendre en ma faveur. Je sais tout le zèle et toute la chaleur avec laquelle vous avez la bonté de défendre et de souscrire ma cause. J’en ai une reconnaissance infinie et vous prie d’être bien assuré de toute l’étendue de ma sensibilité. Quelque peu favorable que puisse être l’issue de ma demande, je vous en aurais toujours la même obligation, et conserverait un souvenir ineffacable des marques que vous me donnez en cette occasion de votre amitié. Le mémoire que vous avez eu la complaisance de dresser à ce sujet ne saurait être mieux frappé ; et j’oserais en graantir l’effet, si nous n’avions à faire à des gens qui ont une façon de penser bien singulière. Cependant, il me restera toujours la satisfaction d’avoir eu le suffrage d'un homme comme vous, recommendable par son discernement, par sa vertu, par ses sentiments, et par l’excellence de son esprit et de son cœur. Je ne sais pas si de cette heure si notre affaire est décidée; elle devrait l’être après les fêtes de la Pentecôte.
Je suis expressément chargé par M. d’Aubais de vous faire savoir son départ de Paris. Il va en Languedoc dans ses propres voitures et à petites journées.Il compte d’être à Nîmes vers le 5 ou le 6 du mois prochain, étant parti le 16 de celui-ci, parce qu’il lui faut vingt ou vingt-deux jours de marche. Il m’aen même temps chargé de vous prier de vous trouveriez quelqu’un qui voulut lui prêter une somme de deux mille livres dont il aura besoin à son arrivée. Vous pourriez voir si vous connaissez quelqu’un de pécunieux qui soit en état de lui prêter cette somme. Il vous fera sans doute savoir lemoment de son arrivée à Nîmes: je crois qu’il ira descendre au logis du Luxembourg. Il vous apporte la petite statue de bronze que M. de Caylus m’avait remise pour vous la faire parvenir. Je viens enfin de déterrer l’adresse de M.l’abbé Mazeas à qui vous avez à faire: c’est son frère même, professeur de philosophie au collège de Navarre, qui me l’a donnée. La voici: à M. l’abbé Mazeas, chanoine de l’église cathédrale de Vannes en Bretagne, à Vannes.
J’attends de vos nouvelles sur notre affaire, et vous prie de croire que j’ai l’honneur d’être dans toute l’étendue des sentiments dont je suis capable, mon cher Monsieur, votre très humble et très obéissant serviteur.

Ménard.

description: The fast nonradiative decay of multiexcitonic states via Auger recombination is a fundamental process affecting a variety of applications based on semiconductor nanostructures. From a theoretical perspective, the description of Auger recombination in confined semiconductor nanostructures is a challenging task due to the large number of valance electrons and exponentially growing number of excited excitonic and biexcitonic states that are coupled by the Coulomb interaction. These challenges have restricted the treatment of Auger recombination to simple, noninteracting electron-hole models. Herein we present a novel approach for calculating Auger recombination lifetimes in confined nanostructures having thousands to tens of thousands of electrons, explicitly including electron-hole interactions. We demonstrate that the inclusion of electron-hole correlations are imperative to capture the correct scaling of the Auger recombination lifetime with the size and shape of the nanostructure. In addition, correlation effects are required to obtain quantitatively accurate lifetimes even for systems smaller than the exciton Bohr radius. Neglecting such correlations can result in lifetimes that are 2 orders of magnitude too long. We establish the utility of the new approach for CdSe quantum dots of varying sizes and for CdSe nanorods of varying diameters and lengths. Our new approach is the first theoretical method to postdict the experimentally known universal volume scaling law for quantum dots and makes novel predictions for the scaling of the Auger recombination lifetimes in nanorods.
