Abstract: It is proved that a general non-differentiable skew convolution semigroup associated with a strongly continuous semigroup of linear operators on a real separable Hilbert space can be extended to a differentiable one on the entrance space of the linear semigroup. A càdlàg strong Markov process on an enlargement of the entrance space is constructed from which we obtain a realization of ...

suitable utilization of daylight in architecture, in addition to meeting the physical and emotional needs of human increase the quality of living spaces. from this perspective, our country's rich architecture has valuable achievements and experiences, which requires recognizing and introducing it to the architectural community of iran and the world. the present research intends to examine ...

Results of recent experiments that clarify the effects of mechanical degradation and viscoelastic behavior on the flow of partially hydrolyzed polyacrylamide solutions through porous media are presented. From these results, a simple model that may be used to predict injectivity of polyacrylamide solutions is developed. Injection pressures for linear corefloods are shown to be separable into two...

Large-conductance Ca(2+)- and voltage-activated K(+) (BK) channels have the largest conductance (250-300 pS) of all K(+)-selective channels. Yet, the contributions of the various parts of the ion conduction pathway to the conductance are not known. Here, we examine the contribution of the entrance to the inner cavity to the large conductance. Residues at E321/E324 on each of the four α subunits...
