• ### Lecture Analytic combinatorics (Part 2) - Chapter 6: Singularity analysis

In this chapter, we present a general approach to the analysis of coefficients of generating functions that is not restricted to polar singularities and extends to a large class of functions that have moderate growth or decay at their dominant singularities. This chapter presents the following content: Prelude, standard function scale, singularity analysis, schemas and transfer theorems.

• ### Lecture Analytic combinatorics (Part 2) - Chapter 7: Applications of singularity analysis

Singularity analysis paves the way to the analysis of a large quantity of generating functions, as provided by the symbolic method expounded in Chapters I–III. In this chapter we illustrate this situation with numerous examples related to languages, permutations, trees, and graphs of various sorts. As in chapter 5, most analyses are organized into broad classes called schemas.

• ### Đề tài " Logarithmic singularity of the Szeg¨o kernel and a global invariant of strictly pseudoconvex domains "

This paper is a continuation of Feﬀerman’s program [7] for studying the geometry and analysis of strictly pseudoconvex domains. The key idea of the program is to consider the Bergman and Szeg¨ kernels of the domains as o analogs of the heat kernel of Riemannian manifolds. In Riemannian (or conformal) geometry, the coeﬃcients of the asymptotic expansion of the heat kernel can be expressed in terms of the curvature of the metric; by integrating the coeﬃcients one obtains index theorems in various settings. ...

• ### Ebook Numerical analysis (2nd edition): Part 2

(BQ) Part 2 book "Numerical analysis" has contents: Boundary value problems, partial differential equations, random numbers and applications, trigonometric interpolation and the FFT, compression, optimization, eigenvalues and singular values.

• ### Lecture Analytic combinatorics (Part 2) - Chapter 4: Complex analysis, rational and meromorphic asymptotics

The purpose of this chapter is largely to serve as an accessible introduction or a refresher of basic notions regarding analytic functions. We start by recalling the elementary theory of functions and their singularities in a style tuned to the needs of analytic combinatorics. Cauchy’s integral formula expresses coefficients of analytic functions as contour integrals. Suitable uses of Cauchy’s integral formula then make it possible to estimate such coefficients by suitably selecting an appropriate contour of integration.

• ### Identifying undamaged beam status based on singular spectrum analysis and wavelet neural networks

In this paper, the identifying undamaged-beam status based on singular spectrum analysis (SSA) and wavelet neural networks (WNN) is presented. First, a database is built from measured sets and SSA which works as a frequency-based filter. A WNN model is then designed which consists of the wavelet frame building, wavelet structure designing and establishing a solution for training the WNN.

• ### Báo cáo khoa học: Identiﬁcation of an atypical insect olfactory receptor subtype highly conserved within noctuids

Olfaction is primarily mediated by the large family of olfactory receptors. Although all insect olfactory receptors share the same structure with seven transmembrane domains, they present poor sequence homologies within and between species. As the only exception, Drosophila melanogaster OR83b and its orthologues define a receptor subtype singularly conserved between insect species.

• ### Báo cáo khoa học: Brain angiogenesis in developmental and pathological processes: neurovascular injury and angiogenic recovery after stroke

Pathophysiologic responses in brain after stroke are highly complex. Thus far, a singular focus on saving neurons alone has not revealed any clinically effective neuroprotectants. To address this limitation, the concept of a neu-rovascular unit was developed. Within this conceptual framework, brain function and dysfunction are manifested at the level of cell–cell signaling between neuronal, glial and vascular elements.

• ### INTRODUCTION TO REAL ANALYSIS

In conclusion, let us outline a diﬀerent argument, very much in the spirit of Lectures 8 and 5. We considered in these lectures the space of polynomials of a certain type (such as x3 + px + q or x5 − x + a) and saw that the set of polynomials with multiple roots separated the whole space into pieces, corresponding to the number of roots of a polynomial. The set of polynomials with multiple roots is a (very singular) hypersurface obtained by equating the discriminant of a polynomial to zero.

• ### Đề tài " The Poincar´e inequality is an open ended condition "

Let p 1 and let (X, d, μ) be a complete metric measure space with μ Borel and doubling that admits a (1, p)-Poincar´ inequality. Then there exists e ε 0 such that (X, d, μ) admits a (1, q)-Poincar´ inequality for every q p−ε, e quantitatively. 1. Introduction Metric spaces of homogeneous type, introduced by Coifman and Weiss [7], [8], have become a standard setting for harmonic analysis related to singular integrals and Hardy spaces. Such metric spaces are often referred to as a metric measure space with a doubling measure. An advantage of working...
