For several plant species, brood size results from the abortion of ovules and seeds. However, these processes have rarely been studied together in wild plants. In some of the leguminous species studied, seed abortion has been found to depend on pollen quality and on the position of the ovule or fruit. The direct consequence for the mother plant is that fruit costs increase as the seed:ovule rat...

Introduction: Prostate brachytherapy is a common treatment for low-risk prostate cancer involving the insertion of needles in precise locations of the prostate to implant rice-like radioactive sources known as seeds. Seed localization in relation to the prostate is one of the major current limitations of intraoperative treatment planning for prostate brachytherapy [1]. This issue limits the eff...

In terms of conceptual structures theory, the objective of our project is the development of a pattern directed inference systemm7]. It is to operate over conceptual graph terms extended to express constraints on the referent values, and the matching mechanism is to combine order sorted uniication with the action of a constraint solver. This combination leverages type representation technology ...

The practice of cross-lingual transfer of speech technology is of increasing concern as the demand for recognition systems in multiple languages grows. Previous work has proved that: firstly, if there is a big difference between the source language and the target language, cross-lingual adaptation may not outperform scratch training even if the training set is limited; secondly, cross-lingual s...

Improvement of local germplasm through artificial selection is regarded as the main force behind maize evolution and diversity in Mexico, the crop's center of origin. This perspective neglects the larger social context of maize evolution. Using a theoretical approach and Mexico-wide data, we show that farmer-led evolution of maize is largely driven by a technological diffusion and appropriation...

The number of operating cotton gins in Texas has steadily declined in the past 40 years from 1400 to less than 280 while the production of cotton has remained at approximately 4-5 million bales. In order to market the 5 million bales with fewer gins, the remaining gins will be processing more seed cotton in the future. It is likely that the cotton ginning industry will be faced with longer seas...

The research objective for production of quality cottonseed that has been a major concern of cottonseed researchers for many years is to: "Identify the genetic variability of cottonseed composition, determine the genetic control of cottonseed traits, and develop preferred cotton· seed quality germplasm; develop an understanding of developmental processes of the plant that leads to improved cott...

The KeeLoq cipher is used in many wireless car door systems and garage openers. Recently the algorithm was studied and several attacks have been published. When a random seed is not used the attack on the system is fairly straight-forward. However when a seed is shared between the remote control and the receiver previous research suggested using highly parallel crypto hardware (like COPACOBANA)...

Drought is one of the most important factors that limits N fixation, growth and yield of soybean. 2 The aim of this study was to determine the effects of water stress, starter N application and seed inoculation on yield and yield components of soybean (cv. Williams). The experiment was conducted in 2010 at the Islamshahr town that located in 12 km of South-west of Tehran, the capital of Iran. T...

Irrigated rapeseed (Brassica napus L.) cultivation is currently expanding in rotation with winter cereals in Iran where its reproductive growth is often exposed to water deficit in many parts, particularly in the south. A two growing seasons (2006-2008) field experiment was conducted at the Experimental Research Center, Shiraz University to study the effects of water stress at different growth ...
