Kinked Ureter

Kinked Experience Curve

How much productivity improvement or cost reduction would be possible when the number of semiconductor chips fabricated increased from one million to two million? How many more wind farms or photovoltaic farms needed to be installed before their unit cost of producing electricity can become parity with unit cost from the fossil power plant? Can the child mortality rate in the world be reduced b...

Recording intracellular (IC) bioelectrical signals is central to understanding the fundamental behaviour of cells and cell networks in, for example, neural and cardiac systems1–4. The standard tool for IC recording, the patch-clamp micropipette5 is applied widely, yet remains limited in terms of reducing the tip size, the ability to reuse the pipette5 and ion exchange with the cytoplasm6. Recen...

PRIMARY LEIOMYOSARCOMA OF THE URETER

Since 1943, fourteen cases of primary leiomyosarcoma of the ureter have been reported in English literature. The fifteenth case is presented here with a brief review of the significant aspects of the previous reports.

Electronic and transport properties of kinked graphene

Local curvature, or bending, of a graphene sheet is known to increase the chemical reactivity presenting an opportunity for templated chemical functionalisation. Using first-principles calculations based on density functional theory (DFT), we investigate the reaction barrier reduction for the adsorption of atomic hydrogen at linear bends in graphene. We find a significant barrier lowering (≈15%...
