From a Half-Filled Cup

Translational Control: A Cup Half Full

Repression of translation of oskar and nanos mRNAs prior to their posterior localization in the egg and embryo is essential for body patterning in Drosophila. The Cup protein is now found to have an important role in repression of both mRNAs, and apparently does so in a manner similar to the action of the Xenopus Maskin protein.

Theory of the half-filled Landau level.

A recent theory of a compressible Fermi-liquid like state at Landau level filling factors ν = 1/q or 1 − 1/q, q even, is reviewed, with emphasis on the basic physical concepts.

Dimerization in a half-filled one-dimensional extended hubbard model.

We use a density-matrix renormalization group method to study quantitatively the phase diagram of a one-dimensional extended Hubbard model at half filling by investigating the correlation functions and structure factors. We confirmed the existence of a novel narrow region with long-range bond-order-wave order that was highly controversial recently between the charge-density-wave phase and Mott ...

Universality of the electronic structure from a half-filled CuO2 plane

We present angle-resolved photoemission spectroscopy data from insulating A2CuO2X2 (A5Sr, Ca; X 5Cl, Br!, Sr2Cu3O4Cl2, and Bi2Sr2MCu2O8 (M5Er, Dy! single crystals, which illustrate that the low-energy electronic structure of the half-filled cuprates are independent of the apical atom. By performing a photon energy dependent study on Ca2CuO2Cl2, we are able to distinguish between features which ...

Alcohol, HCV infection, and liver cirrhosis: is the cup half full or half empty?
