Abstract. Objective: Researchers have yet to explore the effect of physically interactive video game playing on energy expenditure, despite its potential for meeting current minimal daily activity and energy expenditure recommendations. Participants and Methods: Nineteen male college students—12 experienced Dance Dance Revolution (DDR) players and 7 inexperienced players— completed maximal oxyg...

We present a second preimage attack on SHAMATA-512, which is a hash function of 512bit output and one of the first round candidates of the SHA-3 competition. The attack uses differential paths that hold with a probability one and a meet-in-the-middle approach to find second preimages. The time complexity is about 2 computation of the step function and the memory complexity is about 2 blocks of ...

A study published September 12, 1996, in the NEW ENGLAND JOURNAL OF MEDICINE confirms that children exposed to low levels of PCBs in the womb grow up with low IQs, poor reading comprehension, difficulty paying attention, and memory problems.[1] PCBs are a family of toxic industrial chemicals commercialized in 1929 by Monsanto, and now found in nearly all humans on earth. (See REHW #327.) This l...

Commutative Supersingular Isogeny Diffie-Hellman (or CSIDH for short) is a recently-proposed post-quantum key establishment scheme that belongs to the family of isogeny-based cryptosystems. The protocol based on action an ideal class group set supersingular elliptic curves and comes with some very attractive features, e.g. ability serve as “drop-in” replacement standard curve protocol. Unfortun...

The comparative in vitro activity of SMT19969, a novel, narrow-spectrum, nonabsorbable agent, was studied against 50 ribotype-defined Clostridium difficile strains, 174 Gram-positive and 136 Gram-negative intestinal anaerobes, and 40 Gram-positive aerobes. SMT19969 was one dilution more active against C. difficile isolates (MIC range, 0.125 to 0.5 μg/ml; MIC90, 0.25 μg/ml), including ribotype 0...

Mammalian ornithine decarboxylase (ODC) is a very unstable protein which is degraded in an ATP-dependent manner by proteasome 26S, after making contact with the regulatory protein antizyme. PEST regions are sequences described as signals for protein degradation. The C-terminal PEST region of mammalian ODC is essential for its degradation by proteasome 26S. Mammalian histidine decarboxylase (HDC...

BACKGROUND Approximately 3% of children are born small for gestational age (SGA), and approximately 10% of SGA children maintain a small body size throughout childhood and often into adult life. Among short SGA children, growth hormone (GH) therapy increases short-term growth in a dose-dependent manner; experience with long-term therapy is limited. OBJECTIVE To delineate the dose dependency o...

The objectives of this research were to determine the interaction of monensin and haylage supplementation for steers fed 60% dried distillers grains (DDGS) on 1) mineral status, performance, and carcass characteristics, and on 2) ruminal pH, H(2)S, and short-chain fatty acid concentrations. In Exp. 1, Angus-cross steers (n=168; BW=277 ± 67 kg) were blocked by BW and allotted in a 2 × 2 factoria...

Lateral inhibition processing of an image yields subpixel precision in the location of intensity discontinuity edges in a digitized image. The method is illustrated using a 512 x 512 x 8 bit image.
