In nature, bacterial colonies must often cope with hostile environmental conditions. To do so they have developed sophisticated cooperative behaviour and intricate communication capabilities, such as direct cell ± cell physical interactions via extra-membrane polymers, collective production of extracellular `wetting’ fluid for movement on hard surfaces, longrange chemical signalling such as quo...

although lightning is an uncommon phenomenon in nature; it can cause many destructive incidents. in the event of a lightning strike, multiple organs particularly the cardiovascular systems are at risk of injury. short-term mortality depends on its cardiac effects. in this paper, the authors report the development of myocardial infarction and pericardial effusion after lightning injury, a typica...

The history of the weak interactions may be said to have begun with the discovery of beta-decay by Henri Becquerel at the end of the 19th Century [1]. It is still evolving. Insights are expected from experiments ranging from neutrinoless double beta-decay to giant cosmic ray air showers. It has benefitted greatly from Jim Cronin’s studies of strange particles, including but not limited to his d...

This paper uses fractals to model the clustering of cache misses. The clustering of cache misses can be quantified by a single number analog to a fractional dimension, and we are intrigued by the possibility that this number can be used as a measure of software complexity. The essential intuition is that cache misses are a direct reflection of changes in locality of reference, and that complex ...

Let η be a line bundle on a smooth curve X with η^2=0 such that π_η, the double covering induced by η is an etale morphism. Assume also that X_η be the Prym-canonical model of X associated to K_X.η and Q is a rank 4 quadric containing X_η. After stablishing the projective normality of the prym-canonical models of curves X with Clifford index 2, we obtain in this paper a sufficient condition for...

the interactive effects of adjacent buildings on their seismic performance are not frequently considered in seismic design. the adjacent buildings, however, are interrelated through the soil during seismic ground motions. the seismic energy is redistributed in the neighboring buildings through multiple structure-soil-structure interactions (sssi). for example, in an area congested with many nea...

We study a model of decentralised bilateral interactions in a small market where one of the sellers has private information about her value. There are two identical buyers and another seller, apart from the informed one, whose valuation is commonly known to be in between the two possible valuations of the informed seller. This represents an attempt to model alternatives to current partners on b...
