We establish universality limits for measures on a subarc of the unit circle. Assume that μ is a regular measure on such an arc, in the sense of Stahl, Totik, and Ullmann, and is absolutely continuous in an open arc containing some point z0 = e0 . Assume, moreover, that μ′ is positive and continuous at z0. Then universality for μ holds at z0, in the sense that the reproducing kernel Kn (z, t) f...
This paper examines the relationship between consumption-based and option-based risk-neutral moments, providing a technique to explore consumption-based pricing kernel specifications using data from the options markets. Estimators for average risk-neutral moments of each type are proposed and implemented. Option-based average risk-neutral moments are estimated for S&P500 returns using S&P500 fu...
the crude oil, crude protein, crude ash, crude fiber, total phenol and antioxidant activity values, peroxide values, specific gravity, the refraxtive index and acid value of citrullus lanatus and their oils were determined. fatty acid composition of seeds belong to both watermelon were determined by gas chromotography (gc). these oils are important sources of essential fatty acid, linoleic aci...
If K/k is a finite Galois extension of number fields with Galois group G, then the kernel of the capitulation map Clk ~ ClK of ideal class groups is isomorphic to the kernel X(H) of the transfer map H/H’ ~ A, where H = Gal(K/k), A = Gal(K/K) and K is the Hilbert class field of K. H. Suzuki proved that when G is abelian, |G| divides |X(H)|. We call a finite abelian group X a transfer kernel for ...
In the `-Component Order Connectivity problem (` ∈ N), we are given a graph G on n vertices, m edges and a non-negative integer k and asks whether there exists a set of vertices S ⊆ V (G) such that |S| ≤ k and the size of the largest connected component in G−S is at most `. In this paper, we give a kernel for `-Component Order Connectivity with at most 2`k vertices that takes nO(`) time for eve...
The Direct Access File System (DAFS) is an emerging commercial standard for network-attached storage on server cluster interconnects. The DAFS architecture and protocol leverage network interface controller (NIC) support for user-level networking, remote direct memory access, efficient event notification, and reliable communication. This paper describes the design of the first implementation of...
Maize (Zea mays L.) kernel pedicels, including vascular tissues, pedicel parenchyma, placento-chalazal tissue, and the surrounding pericarp, contained two forms of glutamine synthetase (EC 6.3.1.2), separable by anion exchange chromatography under mildly acidic conditions. The earlier-eluting activity (GS(p1)), but not the later-eluting activity (GS(p2)), was chromatographically distinct from t...
هرچند که فیلتر ذره ای (particle filter) ابزاری موثر در ردیابی شیء می باشد، اما یکی از محدودیت های موجود، نیاز به وجود مدلی دقیق برای حالت سیستم و مشاهدات است. بنابراین یکی از زمینه های مورد علاقه محققین تخمین تابع مشاهده با توجه به داده های یادگیری است. تابع مشاهده ممکن است خطی یا غیرخطی در نظر گرفته شود. روش های موجود در تخمین تابع مشاهده با مشکلاتی مواجه هستند. از جمله این مشکلات، وابستگی به ...
We consider the symplectic-induced Ginibre process, which is a Pfaffian point process on plane. Let N be number of points. focus almost-circular regime where most points lie in thin annulus S $\mathcal {S}_{N}$ width O 1 $O\left(\frac{1}{N}\right)$ as ? ? $N \rightarrow \infty$ . Our main results are bulk scaling limits all correlation functions near real axis, and also away from axis. Near lim...
Kernel methods provide a promising new family of algorithms for ma hine learning and data mining appli ations. In parti ular, kernel-based nonlinear lassi ers su h as support ve tor ma hines (SVMs) and kernel sher dis riminants (KFDs) have been found to work well in pra ti al problems. In addition, there are methods for training these algorithms on large-s ale data sets making them very suitabl...
