DNA, the biomolecule that provides the blueprint for life, has a lesser-known identity as a stretchy polymer. The authors have found a flaw in the most common model for DNA elasticity, a discovery ...

In a crystalline solid, the atoms form an ordered lattice. Crystalline solids respond elastically to small deformations: When the applied strain is removed, the macroscopic stress, as well as the ...

THE title of this book, although a little lengthy, describes its contents with accuracy ; it is essentially a study of structure approached through the phenomena of elasticity and plasticity. To give ...

Extensibility characteristics of Avena stem segments treated with gibberellic acid (GA) were investigated in living internodes using a microgrowth method and in partially extracted cell walls ...

Toothpaste, face creams, hair gel, mayonnaise, and ketchup are household items that most people don't think twice about but, in terms of their flow behavior, they have unusual properties. They're all ...

A theory of plasticity is considered in which the yield function is a piecewise linear function of the stresses, the flow law is based on the plastic potential, and the strain-hardening is isotropic ...

It is generally believed that the adaptability of the adult brain mainly takes place in the cortex. However, a new study from the Netherlands Institute for Neuroscience shows that the thalamus, a ...
