Glutamat og GABA: Hovedaktører i nevronal metabolisme
Cultures of dissociated cerebella from 7-day-old mice were maintained in vitro for 1–13 days. GABA biosynthesis and degradation were studiedduring development in culture and pharmacological agents were used to identify the enzymes involved. The amount of GABA increased, whereasthat of glutamate was unchanged during the first 5 days and both decreased thereafter. The presence of aminooxy...
متن کاملOvertaking VEST
VEST is a set of four stream cipher families submitted by S. O’Neil, B. Gittins and H. Landman to the eSTREAM call for stream cipher proposals of the European project ECRYPT. The state of any family member is made of three components: a counter, a counter diffusor and a core accumulator. We show that collisions can be found in the counter during the IV Setup. Moreover they can be combined with ...
متن کاملScaling VEST in Hardware
VEST is an exceptionally efficient cipher family that belongs to the most advanced type of design that offers multi-functionality in one highly efficient module. VEST is readily scaled in hardware. The problem of efficient generation of a secure message digest for scaled ciphers is overcome when VEST is combined with XOR-MAC. XOR-MAC technologies are proven secure but suffer performance restric...
متن کاملVEST Enhanced Smart Cards
VEST is a modern cipher that can be readily deployed to offer increased efficiency and/or improved functionality in smartcards. VEST can also be deployed to assist prevent real world problems such as identity theft and the emulation and cloning of cards. VEST efficiently implements the essential symmetric cryptographic functions in one low-area, highperformance multi-function module. VEST-4 red...
متن کاملOptimal Policy in OG Models
In the present paper general stationary overlapping generations economies with many commodities in every period and many different consumers in every generation are considered. A government maximizes a utilitarian social welfare function, which is the sum of weighted averages of utilities for generations, through fiscal policy, i.e., monetary transfers and taxes. Situations both with and withou...
