Two-dimensional Brownian random interlacements

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

description: We introduce the model of two-dimensional continuous random interlacements, which is constructed using the Brownian trajectories conditioned on not hitting a fixed set (usually, a disk). This model yields the local picture of Wiener sausage on the torus around a late point. As such, it can be seen as a continuous analogue of discrete two-dimensional random interlacements [Comets, Popov, Vachkovskaia, 2016]. At the same time, one can view it as (restricted) Brownian loops through infinity. We establish a number of results analogous to these of [Comets, Popov, Vachkovskaia, 2016; Comets, Popov, 2016], as well as the results specific to the continuous case.

description: The turbulent magnetic diffusivity tensor is determined in the presence of rotation or shear. The question is addressed whether dynamo action from the shear-current effect can explain large-scale magnetic field generation found in simulations with shear. For this purpose a set of evolution equations for the response to imposed test fields is solved with turbulent and mean motions calculated from the momentum and continuity equations. The corresponding results for the electromotive force are used to calculate turbulent transport coefficients. The diagonal components of the turbulent magnetic diffusivity tensor are found to be very close together, but their values increase slightly with increasing shear and decrease with increasing rotation rate. In the presence of shear, the sign of the two off-diagonal components of the turbulent magnetic diffusion tensor is the same and opposite to the sign of the shear. This implies that dynamo action from the shear--current effect is impossible, except perhaps for high magnetic Reynolds numbers. However, even though there is no alpha effect on the average, the components of the alpha tensor display Gaussian fluctuations around zero. These fluctuations are strong enough to drive an incoherent alpha--shear dynamo. The incoherent shear--current effect, on the other hand, is found to be subdominant.

description: Cherry trees together with walnut is one of the most promising and valued trees whose timber may provide over 3000 euros per tree to farmers after growing several decades (30 years in Galicia). However, initial investment associated to the plantation itself and the silviculture operations such as clearing, pruning and thinning together with the lack of production of the land during the life of the stand prevents farmers to plant them. One of the alternatives to overcome these concerns from farmers is to implement silvopastoral practices. Silvopasture not only reduces the tree maintenance costs associated to clearing but allows farmer to deliver animal products from the cherry plantation that otherwise will produce nothing from the understory. An experiment was carried out in Galicia to evaluate the feasibility of implementing silvopasture in cherry plantations, showing that continuous stocking rates of around 8 sheep ha-1 increases carbon sequestration in the soil, soil fertility, pasture biodiversity, tree growth and reduces tree production costs associated with clearing when compared with exclusive cherry plantations managed with herbicides application to control the understory. Moreover, the grass growing season was extended as the drought effect on grass production was less effective under the trees than in open sites.

description: Spaniol and Andrade introduced grvitoelectromagnetism in TEGR by considering superpotentials, times the determinant of tetrads, as the gravitoelectromagnetic fields. However, since this defined gravitoelectromagnetic field strength does not give rise to a complete set of Maxwell-like equations, we propose an alternative definition of the gravitoelectromagnetic field strength: instead of superpotentials, torsions are taken as the gravitoelectromagnetic field strengths. Based on this new proposal we are able to derive a complete set of Maxwell-like equations. We then apply them to obtain explicit expressions of the gravitoelectromagnetic fields both in Schwarzchilds spacetime and for gravitational waves.

The Impact of Hard-Decision Detection on the Energy Efficiency of Phase and Frequency Modulation

description: The central design challenge in next generation wireless systems is to have these systems operate at high bandwidths and provide high data rates while being cognizant of the energy consumption levels especially in mobile applications. Since communicating at very high data rates prohibits obtaining high bit resolutions from the analog-to-digital (A/D) converters, analysis of the energy efficiency under the assumption of hard-decision detection is called for to accurately predict the performance levels. In this paper, transmission over the additive white Gaussian noise (AWGN) channel, and coherent and noncoherent fading channels is considered, and the impact of hard-decision detection on the energy efficiency of phase and frequency modulations is investigated. Energy efficiency is analyzed by studying the capacity of these modulation schemes and the energy required to send one bit of information reliably in the low signal-to-noise ratio (SNR) regime. The capacity of hard-decision-detected phase and frequency modulations is characterized at low SNR levels through closed-form expressions for the first and second derivatives of the capacity at zero SNR. Subsequently, bit energy requirements in the low-SNR regime are identified. The increases in the bit energy incurred by hard-decision detection and channel fading are quantified. Moreover, practical design guidelines for the selection of the constellation size are drawn from the analysis of the spectral efficiency--bit energy tradeoff.

description: We combine Hα emission-line and infrared (IR) continuum measurements of two samples of nearby galaxies to derive dust attenuation-corrected star formation rates (SFRs). We use a simple energy balance based method that has been applied previously to H II regions in the Spitzer Infrared Nearby Galaxies Survey, and extend the methodology to integrated measurements of galaxies. We find that our composite Hα + IR based SFRs are in excellent agreement with attenuation-corrected SFRs derived from integrated spectrophotometry, over the full range of SFRs (0.01-80 M sun yr-1) and attenuations (0-2.5 mag) studied. We find that the combination of Hα and total IR luminosities provides the most robust SFR measurements, but combinations of Hα measurements with monochromatic luminosities at 24 μm and 8 μm perform nearly as well. The calibrations differ significantly from those obtained for H II regions, with the difference attributable to a more evolved population of stars heating the dust. Our results are consistent with a significant component of diffuse dust (the "IR cirrus" component) that is heated by a non-star-forming population. The same methodology can be applied to [O II]λ3727 emission-line measurements, and the radio continuum fluxes of galaxies can be applied in place of IR fluxes when the latter are not available. We assess the precision and systematic reliability of all of these composite methods.

description: El cerezo junto al nogal es una de las especies más prometedoras y valoradas para la producción de maderas nobles que puede producir alrededor de 3000 euros por árbol al agricultor tras varias décadas de crecimiento (30 años en Galicia). Sin embargo, las inversiones iniciales asociadas a la plantación en si misma junto a las operaciones selvícolas tales como desbroces, podas y claras junto a la ausencia de producción a partir del sotobosque limita que los agricultores realicen estas plantaciones. Una de las alternativas para evitar estas limitaciones es implementar prácticas agroforestales. Las prácticas silvopastorales no solamente reducen el coste de mantenimiento de los árboles asociado al desbroce ya que permiten al agricultor proporcionar productos a partir de la plantación de cerezo, que de otra forma no produciría nada a partir del sotobosque. En Galicia, se llevó a cabo un experimento para evaluar la posibilidad de implementar el Silvopastoreo en plantaciones de cerezo, mostrando que una carga ganadera continua de 8 ovejas ha-1 aumenta el secuestro de carbono en el suelo, la fertilidad edáfica, la biodiversidad de las pasto, el crecimiento del arbolado a la vez que reduce los costes de producción del árbol asociados al desbroce cuando se comparaba con plantaciones no pastoreadas de cerezo gestionadas con herbicida como sistema de control del sotobosque. Es más, la estación de crecimiento del pasto se amplió ya que el efecto de la sequía sobre la producción de pasto fue menos efectiva bajo el arbolado que en zonas abiertas.

description: We present the discovery of pulsational variations in the cool magnetic Ap star HD 115226 -- the first high-amplitude rapidly oscillating Ap star discovered with time-series spectroscopy. Using high-resolution spectra obtained with the HARPS instrument at the ESO 3.6-m telescope, we detect radial velocity variations with a period of 10.86 min in Pr III, Nd III, Dy III lines and in the narrow cores of hydrogen lines. Pulsational amplitudes exceed 1 km/s in individual lines of Nd III. The presence of running waves in the stellar atmosphere is inferred from a phase shift between the radial velocity maxima of rare-earth and hydrogen lines. Our abundance analysis demonstrates that HD 115226 exhibits typical roAp spectroscopic signature, notably ionization anomaly of Pr, Nd and Dy. We discuss the discovery of pulsations in HD 115226 in the context of recent spectroscopic studies of roAp stars and point to the existence of correlation between spectroscopic pulsational amplitude and the stellar rotation rate.

description: A large-scale complex system comprising many, often spatially distributed, dynamical subsystems with partial autonomy and complex interactions are called system of systems. This paper describes an efficient algorithm for model predictive control of a class of system of systems for which the overall objective function is the sum of convex quadratic cost functions of (locally) constrained linear subsystems that are coupled through a set of (global) linear constraints on the subsystems coordination parameters. The proposed control algorithm is based on parametrization and splitting of the underlying optimization problem into one global coordination problem and a set of local optimization problems pertaining to individual subsystems. The local optimization problems are solved off-line, via parametric optimization, while the coordination problem is solved on-line. The properties of the local parametric solutions are utilized to solve the coordination problem very efficiently. In particular, it is shown that, for a fixed number of coupling constraints, the coordination problem can be solved with a linear-time algorithm in a finite number of iterations if all subsystems have one-dimensional coordination parameters.

description: Nitration of N-acetyl anilides using a simple combination of AgNO3 and K2S2O8 as a stable nitro source and an oxidant, respectively, was explored. The reaction was practical to operate and proceeded under considerably mild reaction conditions (reflux in acetonitrile) within acceptable reaction time (6 h). The para-substituted N-acetyl anilides gave only ortho-nitrated products in moderate to good yields (30–63% yields). The ortho-, meta-, or non-substituted N-acetyl anilides gave a mixture of nitrated products (30–72% combined yields) with preferentially at the para- over the ortho-position (ortho:para; 1.0:1.1–1.0:2.8).

description: Software engineering education includes not only the education of software engineers but also the education of others about software engineering. From time to time we are called upon to explain "software engineering" to audiences that have never considered the organization or construction of large software systems or dealt with programs larger than a few pages. With little audience experience to build on, this can be a daunting task. This educational item engages the audience in simulated operation of a large system. A dozen volutneers play the parts of databases, communication protocals, and human users in a series of transactions that lead quite innocently to a surprising transaction that actually took place in real life. I have used it with university freshmen; it can potentially be used with groups of hogh-school students or adults who are not computer professionals (and who are uninhibited enough to participate). The preferred group size is 15 to 40. The activity addresses the problems of explaining how large-scale software is constructed from components and what sorts of things can go wrong. It also touches on system integration and evolution, requirements analysis, the software development process, and discrepencies between the users" and the designers" model of a system.

description: Extending the notion of bounded variation, a function $u \in L_c^1(\mathbb R^n)$ is of bounded fractional variation with respect to some exponent $α$ if there is a finite constant $C \geq 0$ such that the estimate \[ \biggl|\int u(x) \det D(f,g_1,\dots,g_{n-1})_x \, dx\biggr| \leq C\operatorname{Lip}^α(f) \operatorname{Lip}(g_1) \cdots \operatorname{Lip}(g_{n-1}) \] holds for all Lipschitz functions $f,g_1,\dots,g_{n-1}$ on $\mathbb R^n$. Among such functions are characteristic functions of domains with fractal boundaries and Hölder continuous functions. We characterize functions of bounded fractional variation as a certain subspace of Whitney's flat chains and as multilinear functionals in the setting of Ambrosio-Kirchheim currents. Consequently we discuss extensions to Hölder differential forms, higher integrability, an isoperimetric inequality, a Lusin type property and change of variables. As an application we obtain sharp integrability results for Brouwer degree functions with respect to Hölder maps defined on domains with fractal boundaries.

description: The synthesis of new benzimidazole-N-acylhydrazone derivatives (11a-p) was carried out in five steps reactions by adding 2-(2-((benzylthio)methyl)-1H-benzimidazol-1-yl) acetohydrazide (9) with various aromatic aldehydes. The compounds were obtained with yields between 50 and 94%. The NMR spectral study of the different compounds (in deuterated dimethyl sulfoxide DMSO-d6) showed that these compounds exist in the form of mixtures of two conformers namely synperiplanar E and antiperiplanar E. Apart from compounds 11e and 11j which have a hydroxyl function in ortho position of the phenyl, all other compounds were obtained as mixtures with ratio between 80 and 93% of synperiplanar conformation E. Compound structures were confirmed by spectroscopic analyses 1H, 13C NMR and high-resolution mass spectrometry (HRMS).

description: Herein we introduce a novel and reusable nanomagnetic copper catalyst (Fe3O4@SiO2-Imine/Thio-Zn(OAc)2) constructed by immobilizing Zn (II) complex on the surface of magnetic nanoparticles functionalized with Imine/Thio group. The structure of the as-constructed Fe3O4@SiO2-Imine/Thio-Zn(OAc)2 nanomaterial was well analyzed by a number of spectroscopic techniques including: FT-IR, SEM, TEM, EDX, XRD, VSM, AAS and ICP-OES. Experimental studies have well revealed that Fe3O4@SiO2-Imine/Thio-Zn(OAc)2 nanomaterial is an ecofriendly and efficient nanocatalyst for synthesis of synthesis of nitriles via cyanation of aryl iodides. The grafting of the zinc catalyst to the surface of magnetic nanoparticles has increased the catalytic activity of the material and also simplified catalyst recovery from the reaction mixture by an external magnet. The Fe3O4@SiO2-Imine/Thio-Zn(OAc)2 nanocatalyst was readily recovered by simple magnetic decantation and can be reused seven cycles without considerable loss in catalytic activity.

description: FRulekit is an experimental production system written in Commonlisp. At its core is an augmented implementation of the OPS Rete pattern matcher. As well as the standard OPS5 conflict resolution strategies of LEX and MEA and an extended strategy, it also allows users to write their own conflict strategies, and incorporates an agenda system for controlling the ordering of rules. It has a trace package which makes it possible to build rule-learning strategies, and supports reason maintenance. FRulekit stands for Frame-Rulekit since working memory elements are frames, and matching against frames are supported. It uses the Parmenidesframe system, so it is assumed that the reader is also familiar with this frame program. See the Parmenides manual (available as /afs/cs/user/pshell/parmenides/parmenides.ps) for documentation. It is assumed that the reader is familiar with production systems. SinceFRulekitgoes beyond OPS-5 in many ways, the OPS-5 syntax is not used. Knowing lisp, especially Common Lisp, is useful but not essential.
Anomalous diffusion in a random nonlinear oscillator due to high frequencies of the noise

description: We study the long time behaviour of a nonlinear oscillator subject to a random multiplicative noise with a spectral density (or power-spectrum) that decays as a power law at high frequencies. When the dissipation is negligible, physical observables, such as the amplitude, the velocity and the energy of the oscillator grow as power-laws with time. We calculate the associated scaling exponents and we show that their values depend on the asymptotic behaviour of the external potential and on the high frequencies of the noise. Our results are generalized to include dissipative effects and additive noise.

description: A mild and efficient approach for the electrochemical conversion of benzyl alcohols to benzaldehydes is reported in homogeneous medium using Carbon/Stainless Steel electrodes and NaCl as mediator with H2SO4 as supporting electrolyte. To achieve excellent product conversion, optimization of the reaction condition with various parameters was carried out in a beaker type cell. In 2 F of current density and ambient temperature, benzyl alcohols electrochemically oxidized to benzaldehydes in 90% yield. The present work demonstrates a green and sustainable route for benzaldehydes preparation and the superiority of electrochemical method for organic synthesis.
The Gaussian Noise Model in the Presence of Inter-channel Stimulated Raman Scattering

Subjects: subject: Signal Processing (eess.SP)

description: A Gaussian noise (GN) model is presented that properly accounts for an arbitrary frequency dependent signal power profile along the link. This enables the evaluation of the impact of inter-channel stimulated Raman scattering (ISRS) on the optical Kerr nonlinearity. Additionally, the frequency dependent fiber attenuation can be taken into account and transmission systems that use hybrid amplification schemes can be modeled, where distributed Raman amplification is partly applied over the optical spectrum. To include the latter two cases, a set of coupled ordinary differential equations must be numerically solved in order to obtain the signal power profile yielding a semi-analytical model. However for lumped amplification and negligible variation in fiber attenuation, a less complex and fully analytical model is presented which is referred to as the ISRS GN model. The derived model is exact to first-order for Gaussian modulated signals and extensively validated by numerical split-step simulations. A maximum deviation of $0.1$~dB in nonlinear interference power between simulations and the ISRS GN model is found. The model is applied to a transmission system that occupies an optical bandwidth of $10$~THz, representing the entire C+L band. At optimum launch power, changes of up to $2$~dB in nonlinear interference power due to ISRS are reported. Furthermore, comparable models published in the literature are benchmarked against the ISRS GN model.

description: Nitration of N-acetyl anilides using a simple combination of AgNO3 and K2S2O8 as a stable nitro source and an oxidant, respectively, was explored. The reaction was practical to operate and proceeded under considerably mild reaction conditions (reflux in acetonitrile) within acceptable reaction time (6 h). The para-substituted N-acetyl anilides gave only ortho-nitrated products in moderate to good yields (30–63% yields). The ortho-, meta-, or non-substituted N-acetyl anilides gave a mixture of nitrated products (30–72% combined yields) with preferentially at the para- over the ortho-position (ortho:para; 1.0:1.1–1.0:2.8).

description: Web macros use the programming-by-example concept to automate user actions within a web browser. Although web macro recorders and players have grown in sophistication over the past decade, we believe that these tools cannot yet meet the needs of real users. Based on observations of browser users, we have compiled various scenarios describing tasks that end users would benefit from automating using web macros. Our analysis of these scenarios yields specific requirements that web macro tools must support if those tools are to be applicable to real-life situations. For example, these opportunities for improvement include better support for triggering macros on events, authenticating to sites, transporting data to/from spreadsheets, taking advantage of data’s semantics, and recovering from errors. Our collection of requirements constitutes a benchmark for evaluating new and improved web macro tools. We developed this corpus as a collaboration within the EUSES Consortium, whose aim is to help End Users Shape Effective Software.

description: A Lévy process on a *-bialgebra is given by its generator, a conditionally positive hermitian linear functional vanishing at the unit element. A *-algebra homomorphism k from a *-bialgebra C to a *-bialgebra B with the property that k respects the counits maps generators on B to generators on C. A tranformation between the corrresponding two Lévy processes is given by forming infinitesimal convolution products. This general result is applied to various situations, e.g., to a *-bialgebra and its associated primitive tensor *-bialgebra (called "generator process") as well as its associated group-like *-bialgebra (called Weyl-*-bialgebra). It follows that a Lévy process on a *-bialgebra can be realized on Bose Fock space as the infinitesimal convolution product of its generator process such that the vacuum vector is cyclic for the L\e'vy process. Moreover, we obtain convolution approximations of the Azéma martingale by the Wiener process and vice versa.

description: We look at simple BPS systems involving more than one field. We discuss the conditions that have to be imposed on various terms in Lagrangians involving many fields to produce BPS systems and then look in more detail at the simplest of such cases. We analyse in detail BPS systems involving 2 interacting Sine-Gordon like fields, both when one of them has a kink solution and the second one either a kink or an antikink solution. We take their solitonic static solutions and use them as initial conditions for their evolution in Lorentz covariant versions of such models. We send these structures towards themselves and find that when they interact weakly they can pass through each other with a phase shift which is related to the strength of their interaction. When they interact strongly they repel and reflect on each other. We use the method of a modified gradient flow in order to visualize the solutions in the space of fields.

description: The popularity of on-line document databases has led to a new problem: finding which text databases (out of many candidate choices) are the most relevant to a user. Identifying the relevant databases for a given query is the text database discovery problem. The first part of this paper presents a practical solution based on estimating the result size of a query and a database. The method is termed GlOSS--Glossary of Servers Server. The second part of this paper evaluates the effectiveness of GlOSS based on a trace of real user queries. In addition, we analyze the storage cost of our approach.
Exogenous origin of hydration on asteroid (16) Psyche: The role of hydrated asteroid families

description: Asteroid (16) Psyche, that for long was the largest M-type with no detection of hydration features in its spectrum, was recently discovered to have a weak 3 micron band and thus it eventually was added to the group of hydrated asteroids. Its relatively high density in combination with the high radar albedo, led to classify the asteroid as a metallic object, possibly a core of a differentiated body, remnant of "hit-and-run" collisions. The detection of hydration is, in principle, inconsistent with a pure metallic origin of this body. Here we consider the scenario that the hydration on its surface is exogenous and was delivered by hydrated impactors. We show that impacting asteroids that belong to families whose members have the 3 m band can deliver the hydrated material to Psyche. We developed a collisional model with which we test all the dark carbonaceous asteroid families, which contain hydrated members. We find that the major source of hydrated impactors is the family of Themis, with a total implanted mass on Psyche to be of the order of 10^14 kg. However, the hydrated fraction could be only a few per cent of the implanted mass, as the water content in carbonaceous chondrite meteorites, the best analogue for the Themis asteroid family, is typically a few per cent of their mass.

description: We study lattice embeddings for the class of countable groups $Γ$ defined by the property that the largest amenable uniformly recurrent subgroup $A_Γ$ is continuous. When $A_Γ$ comes from an extremely proximal action and the envelope of $A_Γ$ is co-amenable in $Γ$, we obtain restrictions on the locally compact groups $G$ that contain a copy of $Γ$ as a lattice, notably regarding normal subgroups of $G$, product decompositions of $G$, and more generally dense mappings from $G$ to a product of locally compact groups.

description: We generalise the variant of the Babylonian tower theorem for vector bundles on projective spaces proved by I. Coanda and G. Trautmann (2006) to the case of principal $G$-bundles over projective spaces, where $G$ is a linear algebraic group defined over an algebraically closed field. In course of the proofs some new insight into the structure of such principal $G$-bundles is obtained.

description: Addressed herein is the effective catalytic performance of palladium nanoparticles supported on mesoporous graphitic carbon nitride (mpg-CN/Pd) for the Heck coupling reaction of alkenes with various aryl halides. The presented catalytic C–C bond formation reaction was carried out in a high-pressure glass tube for 4 hours in an aqueous solution EtOH/H2O (v/v 2/1). The corresponding alkene products were obtained in relatively high yields as E-selective under the optimized conditions. The catalyst's utility in the Suzuki cross-coupling reaction was also investigated under almost identical conditions. Moreover, these reactions proceeded smoothly with both electron-rich and electron-deficient aryl iodides and aryl bromides. The nanocatalyst can be recovered from the reaction medium by centrifugation. It can be reused by preserving approximately 92% of its initial catalytic activity after the five consecutive reactions.

description: We propose a conceptual design for a quantum blockchain. Our method involves encoding the blockchain into a temporal GHZ (Greenberger-Horne-Zeilinger) state of photons that do not simultaneously coexist. It is shown that the entanglement in time, as opposed to an entanglement in space, provides the crucial quantum advantage. All the subcomponents of this system have already been shown to be experimentally realized. Furthermore, our encoding procedure can be interpreted as nonclassically influencing the past.

description: Distributed denial-of-service (DDOS) attacks have emerged as a prevalent way to compromise the availability of networks/servers, which imposed financial losses for e-commerce businesses. Many defenses that mitigate the effect of ongoing DDOS attacks have been proposed. However, none of the defenses have been widely deployed on the Internet infrastructure at this point because of a lack of understanding in the economic incentives inherent in providing the defenses as well as uncertainty in current defenses. We propose that ISPs should provide DDOS defenses as network services to ensure the availability of a network or a server when the technology is ready. This paper provides an analytical framework for the proposed service to align the economic incentives. Using empirical data from security incidents, this paper shows that the proposed service can bring economic benefits to providers with an appropriate pricing strategy, some investigation into the expected loss of subscribers, and knowledge on the overall risk level of attacks.

description: Herein we introduce a novel and reusable nanomagnetic copper catalyst (Fe3O4@SiO2-Imine/Thio-Zn(OAc)2) constructed by immobilizing Zn (II) complex on the surface of magnetic nanoparticles functionalized with Imine/Thio group. The structure of the as-constructed Fe3O4@SiO2-Imine/Thio-Zn(OAc)2 nanomaterial was well analyzed by a number of spectroscopic techniques including: FT-IR, SEM, TEM, EDX, XRD, VSM, AAS and ICP-OES. Experimental studies have well revealed that Fe3O4@SiO2-Imine/Thio-Zn(OAc)2 nanomaterial is an ecofriendly and efficient nanocatalyst for synthesis of synthesis of nitriles via cyanation of aryl iodides. The grafting of the zinc catalyst to the surface of magnetic nanoparticles has increased the catalytic activity of the material and also simplified catalyst recovery from the reaction mixture by an external magnet. The Fe3O4@SiO2-Imine/Thio-Zn(OAc)2 nanocatalyst was readily recovered by simple magnetic decantation and can be reused seven cycles without considerable loss in catalytic activity. Fe3O4@SiO2-Imine/Thio-Zn(OAc)2 catalyzed synthesis of nitriles via cyanation of aryl iodides
