In this project, the Faddeev-Watson-Lovelace (FWL) formalism is generalized to large scattering angles.The angular range includes 0-180 degrees.Using this method, the charge transfer differential cross-sections are calculated, in a second-order approximation, for collision of energetic positrons and electrons with neutral positronium atoms.In this

Humans ( Homo sapiens ) and chimpanzees ( Pan troglodytes ) can extract socially-relevant information from the static, non-expressive faces of conspecifics.In humans, the face is a valid signal of both personality and health.Recent evidence shows that, like humans, chimpanzee faces also contain personality information, and that humans can accuratel

Tissues in the body are hierarchically structured composite materials with tissue-specific chemical and topographical properties.Here we report the preparation of tissue scaffolds with macroscopic pores generated via REVAMP the dissolution of a sacrificial supramolecular polymer-based crystal template (urea) from a biodegradable polymer-based scaff

Lung cancer is the second most common type Double UPH Bench (1/CN) of cancer in the world and is the most common cause of cancer-related death in men and women; it is responsible for 1.3 million deaths annually worldwide.It can metastasize to any organ.The most common site of metastasis in the head and neck region is the brain; however, it can also
