Moreover, Layers generates a finetunable coarse model for the molecular surface by using nonrandom sampling. The coarse model can be used for shape comparison, protein recognition and ligand design.
Life as we know it on the Earth is entirely dependent on the tenuous layer of gas that clings to the surface of the globe, adding about 1% to its diameter and an insignificant amount to its total mass.
Although Venus is similar to the Earth in size and mass, its surface and atmosphere differ from our planet. Resurfacing in the planet's past may have created a solid crust, and the hidden core ...

The structures and functions of the eyes are complex. Each eye constantly adjusts the amount of light it lets in, focuses on objects near and far, and produces continuous images that are instantly transmitted to the brain. The orbit is the bony cavity that contains the eyeball, muscles, nerves, and ...

The surface of the mucosa is a layer of nonciliated simple ...
May 01, 2002· The metal film structure is critically affected by the surface structure in the early stage of its growth on a semiconductor substrate. Pt adsorption on Si is particularly interesting because Pt is chemically stable and has a high melting point.
The respiratory membrane, also called the respiratory surface, is made of the alveolar epithelial cell and the pulmonary capillary endothelial cell, and this structure helps exchange the gases of carbon dioxide and oxygen.
amount and depth of deformation of the surface layers. Many of the surfaces are chemically reactive. With the exception of noble metals, all metals and alloys ... Analysis of Surface Roughness Surface texture is the repetitive or random deviation from the nominal surface that forms the three
These structures are configured to accommodate the stability and mobility responsibilities of the foot and ankle on various surfaces during varying degrees of weight bearing.
The Sun's Surface The deepest layer of the Sun you can see is the photosphere. The word ``photosphere'' means ``light sphere''. ... the flux of energy at its surface = × (the Sun's surface temperature) 4, ... called helmet streamers, and fainter, straight structures .
