Diatom Structures Templated by Phase-Separated Fluids

Diatom structures templated by phase-separated fluids.

An experimentally motivated model is proposed for the formation of fluid-phase templates corresponding to the porous silica skeletons of diatoms, single-cell organisms found in marine and freshwater environments. It is shown that phase-separation processes on a planar surface may give rise to a quasi-static mold that could direct the deposition of condensing silica to form complex arrays of por...

modeling loss data by phase-type distribution

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...

RNA-templated DNA origami structures.

Using the RNA transcript as a template, RNA-templated DNA origami structures were constructed by annealing with designed DNA staple strands. RNA-templated DNA origami structures were folded to form seven-helix bundled rectangular structures and six-helix bundled tubular structures. The chemically modified RNA-DNA hybrid origami structures were prepared by using RNA templates containing modified...

Anion templated assembly of mechanically interlocked structures.

This tutorial review describes the evolution of the field of chemical templation, in particular, emphasising the impact its application has made to the synthesis of mechanically interlocked structures. Recent advances in the use of negatively charged template species for the synthesis of interlocked structures are detailed, with the main focus of this review describing the development of a gene...
