In this paper, an efficient encryption technique is proposed, especially for JPEG2000 compatible images. The technique uses a multilayer neural network to generate a pseudo-random sequence for transforming wavelet subbands into cipher subbands. The neural network generator takes 64 bit key as a startup seed with additional 64 bit key for initial weights and biases. At each layer, output is calc...

Respondent driven sampling (RDS) is a network sampling technique typically employed for hard-to-reach populations (e.g. drug users, men who have sex with men, people with HIV). Similar to snowball sampling, initial seed respondents recruit additional respondents from their network of friends. The recruiting process repeats iteratively, thereby forming long referral chains. Unlike in snowball sa...

Among the various stages of fruit harvest (35, 40, 45 DFP under open field (E1); and 45, 50, 55 protected (E2) environments, in combination with post-harvest ripening (PHR) periods (0, 10, 20 30-days);treatment F2P4 (40 DFP+30-days PHR), followed by F3P3 (45 DFP+20-days PHR) field, whereas, treatment C2P4 (50 C3P3 (55 environment, were superior optimizing both seed yield quality two cucumber va...

The membrane components of the castor bean spherosomes were characterized. The storage triacylglycerols of isolated spherosomes were extracted with diethyl ether, and the membrane was isolated by sucrose gradient centrifugation. It had an apparent equilibrium density of 1.12 grams per cubic centimeter, and possessed an antimycin A-insensitive NADH cytochrome c reductase and an acid lipase. Phos...

Fruits of Trichilia cuneata (Meliaceae), a common tree in dtiet fotests of Central America, are eaten by a numbet of birds. The fruits are 10 to 12 mm in diameter, covered by a yellowish-brown, capsular exocarp, and contain three to six seeds distributed among three locules. Each seed is covered by an orangish-red aril that averages 59.7 percent lipid and 15.1 petcent protein, which makes this ...

BACKGROUND One of the major problems of the aged women or older than 35 is getting pregnant in the late fertility life. Fertility rates begin to decline gradually at the age of 30, more so at 35, and markedly at 40. Even with fertility treatments such as in vitro fertilization, women have more difficulty in getting pregnant or may deliver abnormal fetus. The purpose of this study was to assess ...

We had previously demonstrated that expression of a cytoplasmic-localized ADPglucose pyrophosphorylase (AGPase) mutant gene from Escherichia coli in rice endosperm resulted in enhanced starch synthesis and, in turn, higher seed weights. In this study, the levels of the major primary carbon metabolites were assessed in wild type and four transgenic CS8 rice lines expressing 3- to 6-fold higher A...

We present an approach to the discovery of semantically similar terms that utilizes a web search engine as both a source for generating related terms and a tool for estimating the semantic similarity of terms. The system works by associating with each document in the search engine’s index a weighted term vector comprising those phrases that best describe the document’s subject matter. Related t...

Greenhouse and field experiments with American ginseng (Panax quinquefolius L.) stratified seed sown at depths of 10 to 100 mm were carried out to determine effects of seeding depth on seedling emergence, growth and development and to calculate optimum seeding depth. The time to 50% seedling emergence (E50) in the field increased linearly from 17 d at 20 mm seeding depth to 42.5 d at 80 mm. See...

The verde plant bug, Creontiades signatus (Distant), has been present in south Texas for several years but has more recently been documented as an economic threat to cultivated cotton, (Gossypium hirsutum L. Our studies over 2 yr (2009 and 2010) and two locations (Weslaco and Corpus Christi, TX) investigated feeding-injury of the verde plant bug to a range of cotton boll age classes defined by ...
