We analyze the two-player game of Knock ’em Down, asymptotically as the number of tokens to be knocked down becomes large. Optimal play requires mixed strategies with deviations of order √ n from the naive law-of-large numbers allocation.

RNA interference (RNAi) is a powerful tool to analyze gene function in mammalian cells. However, the interpretation of RNAi knock-down phenotypes can be hampered by off-target effects or compound phenotypes, as many proteins combine multiple functions within one molecule and coordinate the assembly of multimolecular complexes. Replacing the endogenous protein with ectopic wild-type or mutant fo...

behaviour studies indicated that the permethrin resistant strin of an. stephensi was 3-fold resistant to knock-down compared with the susceptible strain. the resistant strain was however 3-fold less irritable to permethrin and less responsive than the susceptible strain to the movement of an aspirator. if reduced irritability and reduced responsiveness to catch are consequences of the changes i...

BACKGROUND Protein-tyrosine kinases (PTKs) regulate virtually all biological processes. PTKs phosphorylate substrates in a sequence-specific manner and relatively short peptide sequences determine selectivity. Here, we developed new technology to determine PTK activity profiles using peptide arrays. The zebrafish is an excellent model system to investigate signaling in the whole organism, given...

Fibrillin4 (FBN4) is a protein component of plastoglobules, which are antioxidant-rich sub-compartments attached to the chloroplast thylakoid membranes. FBN4 is required for normal plant biotic and abiotic stress resistance, including bacterial pathogens, herbicide, high light intensity, and ozone; FBN4 is also required for the accumulation of osmiophilic material inside plastoglobules. In this...

Objective(s): ShRNA-mediated silencing strategy is considered to be a potent therapeutic approach. The present study aimed to assess the ability of the previously prepared polyethylenimine (PEI) derivative for the shRNA knock-down of the CD200 gene on the cells obtained from the patients with chronic lymphocytic leukemia (CLL). Materials and Methods: Since there are several investigations...

The present work is an experimental account of the way in which several machine settings, particularly cylinder knock-over and dial-height, influence fabric dimensions, course length, bending behavior and load extension of fabrics produced on a circular knitting machine. The results show that there are certain optimum settings for such variables as knock-over depth and dial-height for producing...
