We prove that for the mean curvature flow of closed embedded hypersurfaces, intrinsic diameter stays uniformly bounded as approaches first singular time, provided all singularities are neck or conical type. In particular, assuming Ilmanen’s multiplicity one conjecture and no cylinder conjecture, we conclude in two-dimensional case always bounded. also obtain sharp $$L^{n-1}$$ bound curvature. T...

objective(s): in this study, drug loaded electrospun nanofibrous mats were prepared and drug release and mechanism from prepared nanofibers were investigated.  materials and methods: paclitaxel (ptx) loaded polylactic acid (pla) nanofibers were prepared by electrospinning. the effects of process parameters, such as ptx concentration, tip to collector distance, voltage, temperature and flow rate...

Long baseline interferometric observations of δ Cep at the ”Grand Interféromètre à deux Télescopes” give the first measurement of its mean angular diameter. Combined with the mean linear radius deduced from spectroscopic data, the mean angular diameter gives an improved distance determination for δ Cep. Size pulsations aremarginally detected and themeasured amplitude is consistent with the theo...

Electrospun fibrous materials have increasing applications in regenerative medicine due to the similarity of fibre constructs to the morphology of certain extracellular matrices. Although experimentally the electrospinning method is relatively simple, at the theoretical level the interactions between process parameters and their influence on the fibre morphology is not yet fully understood. Her...

The notion of strongly quotient graph (SQG) was introduced by Adiga et al. (2007). In this paper, we obtain some better results for the distance energy and the distance Estrada index of any connected strongly quotient graph (CSQG) as well as some relations between the distance Estrada index and the distance energy. We also present some bounds for the distance energy and the distance Estrada ind...
