We study the dynamics of a cavitation bubble near beds sand different grain sizes. use high-speed imaging to observe motion and for values stand-off parameter $\gamma$ (dimensionless bubble-boundary distance) between 0.3 5.3. Compared with rigid boundary, we find that granular boundary leads bubbles shorter lifetimes reduced centroid displacements. Above $\gamma \approx 1.3$ , behaviour is almo...

In order to produce components in optical quality in ultra-precision cutting processes it is very important to have a highly balanced system. Achieving the best possible balancing state is a time consuming process. Therefore, the prediction of the influence of the balancing state on the surface quality of the component is desirable. On the other hand, such a model should enable us to predict a ...

We consider Arthur-Merlin proof systems where (a) Arthur is a probabilistic quasi-polynomial time Turing machine, denoted AMqpoly, and (b) Arthur is a probabilistic exponential time Turing machine, denoted AMexp . We prove two new results related to these classes. We show that if co-NP is in AMqpoly then the exponential hierarchy collapses to AMexp. We show that if SAT is polylogarithmic round ...

In mammalian cells, protein degradation is an essential and dynamic process that is crucial for survival, growth, differentiation and proliferation of cells. Tellingly, the majority of intracellular proteins are degraded via the ubiquitin–proteasome system (UPS). UPS-mediated protein degradation serves qualitative and quantitative roles within the cellular proteome. For instance, UPS specifical...

A Langmuir monolayer of stearic acid on pure water and in the presence of certain divalent metal ions such as Cd and Pb at pH approximately 6.5 of the subphase water collapses at constant area, while for other divalent ions such as Mg, Co, Zn, and Mn at the same subphase pH the monolayer collapses nearly at constant pressure. Films of stearic acid with Cd, Pb, Mn, and Co in the subphase (at pH ...

japan is a region of active plate tectonics, well known for its japanese trench a geological feature evolving as a result of north pacific (np) oceanic plate pushing and sub-ducting underneath the north american (na) plate. multiple plate tectonics have been continuously recorded in the region since 1979 by the network of gps stations called geonet. the network operating and monitoring more tha...

The OSS (acronym of the Italian “Osservatorio Sismico delle Strutture”) is a network permanent seismic monitoring systems installed on about 150 buildings in Italy. Each system consists number sensors sufficient to completely describe dynamic response structure. Structural typologies have been selected according their representativeness public building stock and importance for emergency managem...
