A Large Sieve Zero Density Estimate for Maass Cusp Forms Paul Dunbar Lewis The large sieve method has been used extensively, beginning with Bombieri in 1965, to provide bounds on the number of zeros of Dirichlet L-functions near the line σ = 1. Using the Kuznetsov trace formula and the work of Deshouillers and Iwaniec on Kloosterman sums, it is possible to derive large sieve inequalities for th...

Combining the arguments developed in [2] and [7], we introduce a smoothing device to the sieve procedure [3] of D.A. Goldston, J. Pintz, and C.Y. Yıldırım (see [4] for its simplified version). Our assertions embodied in Lemmas 3 and 4 imply that an improvement of the prime number theorem of E. Bombieri, J.B. Friedlander and H. Iwaniec [1] should give rise infinitely often to bounded differences...

Sedimentation has been a standard methodology for particle size analysis since the early 1900s. In recent years laser diffraction is beginning to replace sedimentation as the prefered technique in some industries, such as marine sediment analysis. However, for the particle size analysis of soils, which have a diverse range of both particle size and shape, laser diffraction still requires evalua...

In this paper, we study several variations of the number field sieve to compute discrete logarithms in finite fields of the form Fpn , with p a medium to large prime. We show that when n is not too large, this yields a Lpn(1/3) algorithm with efficiency similar to that of the regular number field sieve over prime fields. This approach complements the recent results of Joux and Lercier on the fu...

We have obtained gram quantities of clean, viable eggs of Meloidogyne incognita by a method which combined treatment with hypochlorite and differential centrifugation. Chili pepper plants (Capsicum frutescens L.) infected with M. incognita were dug at harvest from a naturally infested field. Egg sacs from roots of 50 plants were obtained by kneading the washed roots in water and recovering the ...

Long distance transport in plants occurs in sieve tubes of the phloem. The pressure flow hypothesis introduced by Ernst Münch in 1930 describes a mechanism of osmotically generated pressure differentials that are supposed to drive the movement of sugars and other solutes in the phloem, but this hypothesis has long faced major challenges. The key issue is whether the conductance of sieve tubes, ...

This paper examines the portability of Stanford’s multi-pass rule-based sieve coreference resolution system to inflectional language (Polish) with a different annotation scheme. The presented system is implemented in BART, a modular toolkit later adapted to the sieve architecture by Baumann et al. The sieves for Polish include processing of zero subjects and experimental knowledge-intensive sie...

Based on the mechanical test (shear test, compression test), bond model of corn kernel and straw was established to explore rolling crushing effect different rollers. The type roller is different. material process by force (extrusion kneading) analysis reveals that disc (DCR) has characteristics large unit-length kneading area; spiral-notched serrated (SNSCR) transverse shearing material; they ...
