In Codeplay’s Sieve C++, the programmer can place code inside a “sieve block” thereby instructing the compiler to delay writes to global memory and apply them in order on exit from the block. The semantics of sieve blocks makes code more amenable to automatic parallelisation. However, strictly queueing writes until the end of a sieve block incurs overheads and is typically unnecessary. If the p...

Ca2+-binding proteins in the watery saliva of Megoura viciae counteract Ca2+-dependent occlusion of sieve plates in Vicia faba and so prevent the shut-down of food supply in response to stylet penetration. The question arises whether this interaction between aphid saliva and sieve-element proteins is a universal phenomenon as inferred by the coincidence between sieve-tube occlusion and salivati...

Crystallisation is a complex process that significantly affects the rheology of magma, and thus flow dynamics during volcanic eruption. For example, evolution crystal fraction, size shape has strong impact on surface crust formation lava flow, accessing such information essential for accurate modelling dynamics. To investigate role crystallisation kinetics behaviour, we performed real-time, in ...

Introduction: Over the years, there have been many proposed mechanisms for moon formation, including fission, capture, and coaccretion, but the most popular and ever-evolving model at present is the giant impact origin [1]. The impact origin points to the existence of a hot, young moon, likely with a global magma ocean [2]. The next logical step, based on the mantle cumulate crystallization seq...
