Quantifying field weeds emergence pattern of weeds in rapeseed (Brassica napus L.) under weather conditions of Khuzestan, Iran

In order to quantifying emergence pattern of rapeseed weeds, this experiment was conducted in 40 plots (40 quadrates at Agricultural Sciences and Natural Resources University of Khuzestan, and 30 fields of Bavi (30 quadrates), Ahvaz, Iran, in 2016-2017 growing seasons was monitored, counted and recorded weekly. Three different emergence pattern of nine weed species were identified, Prickly lett...

Quantifying growing versus non-growing ovarian follicles in the mouse

BACKGROUND A standard histomorphometric approach has been used for nearly 40 years that identifies atretic (e.g., dying) follicles by counting the number of pyknotic granulosa cells (GC) in the largest follicle cross-section. This method holds that if one pyknotic granulosa nucleus is seen in the largest cross section of a primary follicle, or three pyknotic cells are found in a larger follicle...

Forcing Complexity: Minimum Sizes of Forcing Conditions

This note is a continuation of our former paper “Complexity of the r-query tautologies in the presence of a generic oracle” (Notre Dame J. Formal Logic 41 (2000)). We give a very short direct proof of the nonexistence of t-generic oracles, a result obtaind first by Dowd (Inform. and Comput. 96 (1992)). We also reconsitute a proof of Dowd’s result that the class of all r-generic oracles in his s...

Visualizing Patterns in the Poincaré Plot of a Magnetic Field

In the development of magnetic fusion reactors which will be the source for future low cost power physicists must be able to analyze the magnetic fields that confine the burning plasma. The corresponding magnetic fieldlines have a periodic or quasi-periodic behavior. In this paper we describe a simple and efficient geometric technique that allows for effective visualization and topological anal...

Human papillomaviruses: a growing field.

A combination of functional studies on human papillomavirus (HPV) oncoproteins and epidemiological studies on persistence of HPV infection firmly established a role for HPV in the etiology of cervical cancers. Understanding the viral life cycle of HPVs has been more difficult. In this issue of Genes & Development, Wang et al. (pp. 181 - 194) describe an efficient method to propagate infectious ...
