A fluid conduit passes through the heat exchanger such that a cooling region is positioned within each of the flow paths. A dispenser is positioned to dispense evaporative liquid on one of the cooling regions. The dispenser operates in a wet mode and a dry mode.

Abstract: A coded signal is received via a physical channel. The coded signal is encoded by a parity check matrix. In some examples, the coded signal is low density parity check-encoded. The coded signal is decoded to determine a result signal. Said decoding alternatingly updates, for each one of a number of iterations, bit node values representing bits of the result signal and check node values representing constrains of the parity check matrix. In some examples, the decoding determines the result signal at a first precision and updates at least partly at a second precision which is lower than the first precision. In further examples, the number of iterations is dynamically adjusted.

Abstract: The present invention is directed to methods and compositions for blocking the effect of the intronic inhibitory splicing region of intron 7 of the SMN2 gene. The compositions and methods of the instant invention include short oligonucleotide reagents (e.g., oligoribonucleotides) that effectively target sites in the SMN2 pre-mRNA, thereby modulating the splicing of SMN2 pre-mRNA to include exon 7 in the processed transcript. The short target regions are 8-mers and 5-mers and also include the identification of a single nucleotide base that is essential for initiating a long distance stearic inhibitory interactions as well as novel targets distant from intron 7 which block the intronic inhibitory splicing of the same. These short target regions and concomitant inhibitory blocking oligonucleotides are less expensive and easier to manufacture and are small enough to cross the blood brain barrier.
