Title: Method of inducing an enhanced immune response against hiv
Inventor: EMINI EMILIO A
IPC: A61K39/00
Filed: 2003-03-12
Abstract: An efficient means of inducing an immune response against human immunodeficiency virus (HIV) utilizing specific prime-boost regimes is disclosed. The specific prime-boost regimes employ a heterologous prime-boost protocol employing recombinant adenoviral vectors of alternative and distinct serotypes comprising exogenous genetic material encoding a common HIV antigen.  Vaccines administered into living vertebrate tissue in accordance with the disclosed regimes, preferably a mammalian host, such as a human or a non-human mammal of commercial or domestic veterinary importance, express the HIV-1 antigen (e.g., Gag), inducing a cellular immune response which specifically recognizes HIV-1. It is believed that the disclosed prime/boost regime will offer a prophylactic advantage to previously uninfected individuals and/or provide a therapeutic effect by reducing viral load levels within an infected individual, thus prolonging the asymptomatic phase of HIV-1 infection.

Abstract: In processing of calculating outer value log-ratio .alpha.mn by a row processing unit performing an operation on rows of a parity check matrix, a minimum absolute value and a second minimum absolute value out of data utilized for the row processing are stored. When the data to be processed matches with the minimum value, the second minimum value is outputted. When the data to be processed does not match with the minimum value, the minimum value is output. Thus, it is possible to simplify a construction of a portion for executing Min operation of obtaining a minimum value in the processing of a decoding operation according to a min-sum decoding algorithm. It is possible to reduce a scale of circuitry for decoding low density parity check codes.

Abstract: In a general dynamic temperature targeted application of cooling via carbon dioxide snow, pellets or blocks to fission reactors, the system will cool the water encasings of fissile materials in nuclear reactor cores, during normal operations and emergency operations, temporary overheating events, fuel replacement operations, arid furnish contingency cooling for steam releases, steam explosions, and reactor basement circulation events. This system has components and delivery sites, which will treat cooling water and replace the necessity of a cooling tower. This system will cool cooling water from the reactor via either or both the outlet arid the inlet routes, heavy or light water core cooling systems, and it will improve upon cooling delivered to fuel channels by providing rapid removal or stripping of undesired thermal events or fluxes.  The system will include CO2 dry ice delivery that is either recovered and recycled, or not recycled and reused. The system will include direct natural heat exchange through metallic barriers such as cooling fins and exchangers and the encased cooling water from any point on a fission reactor, and include large multi tonne delivery of CO2 ice to small quantities of CO2 ice over time or in emergency, to achieve the desired cooling, which may or may not include freezing of the target coolant, water or heavy water, liquid metal coolant, liquid or gaseous transition metal coolants, or and inert intermediate compound. The concept of heat stripping is described as Cryolysis, which is the consistent and scientific application of cooling in a dynamic flow using carbon dioxide ice.
