In recent years, there has been growing interest in interaction of metal complexes with nucleic acids and in particular for their ability to cleave DNA [1-5]. Some important nucleolytes are Ctt(lI)-OP [2], Fe(I1)-BLM [3], Fe(II)-EDTA [4], metalloporphyrins [5], Cu arid Co complexes of substituted phenanthrolines [6] and Ni(ll) complexes of azamacrocycles [7] and a tripeptide GlyGly-His [18]. Th...

We analyze how economic shocks and policies a¤ect the intensity of social con‡ict. We show that not all shocks that could make society richer reduce con‡ict. In our model, positive shocks to labor intensive industries diminish social con‡ict, while positive shocks to capital intensive industries increase it. The key requirement is that appropriation activities be more labor intensive than the e...

Sodium channels consist of a pore-forming a subunit and auxiliary b1 and b2 subunits. The subunit b1 alters the kinetics and voltage-dependence of sodium channels expressed in Xenopus oocytes or mammalian cells. Functional modulation in oocytes depends on speci®c regions in the N-terminal extracellular domain of b1, but does not require the intracellular C-terminal domain. Functional modulation...

Some alternatives to the traditional mixing-length theory (MLT) have recently been proposed for modelling convective heat transport inside stars. The ideal formulation is one that does not involve any free parameters. However, in our present state of ignorance we still need at least one free parameter in order to build solar models with the correct radius. Having adjusted this parameter (e.g. t...

We study information acquisition in a coordination game with incomplete information. To capture the idea that players can exibly decide what information to acquire, we do not impose any physical restriction on feasible information structure. Facing an informational cost measured by reduction of Shannon's entropy, players collect information most relevant to their welfare and are rationally inat...

With the advent of cognitive radio technology, new paradigms for spectrum access can achieve nearoptimal spectrum utilisation by letting each user sense and utilise available spectrum opportunistically while regulating the interference it imposes on other users through interference constraints. However, the most common forms of binary and transmitter-centric constraints are often inef cient sin...

The generative communication paradigm of parallel programming ooers not only simplicity, but power and ex-ibility. However, the properties of associative access and uncoupled communication that give rise to this power and exibility also lie at the heart of the compiler and run-time system implementation challenges, especially on distributed memory systems. This paper provides concrete steps tow...

. â€M̃etastatic' †̃ brain tumors were produced in female Wistan rats by intracarotid inoculation of Walker 256 carcinoma cells and subsequent treatment with small doses of cycbophospha mide (CTX) which eradicated extnacnanial tumors, giving time for intracranial tumors to grow. Seven drugs currently in use for brain tumor chemotherapy were tested using this model. After toxicity for each drug w...
