Dowling-Degos disease is a rare autosomal dominant inherited pigmentary disorder characterized by reticulate pigmentation of the flexures, prominent comedone like lesions and pitted scars. Dyschromatosis universalis hereditaria is characterized by the presence of hypopigmented as well as hyperpigmented macules. We report a family showing features of both these diseases.

We apply genetic programming to the evolution of strategies for playing the game of backgammon. Pitted in a 1000-game tournament against a standard benchmark player—Pubeval—our best evolved program wins 58% of the games, the highest verifiable result to date. Moreover, several other evolved programs attain win percentages not far behind the champion, evidencing the repeatability of our approach.

Fermi LAT (Large Area Telescope) and GBM (Gamma ray Burst Monitor) observations of GRBs are briefly reviewed, keeping in mind EGRET expectations. Using γγ constraints on outflow Lorentz factors, leptonic models are pitted against hadronic models, and found to be energetically favored. Interpretation of the Fermi data on GRBs helps establish whether GRBs accelerate cosmic rays, including those r...

Background and objectivesThis work aimed to evaluate the phenolic profile antioxidant capacity of water extracts three different date seed varieties i.e., Aseel, Karbalaen Khupro. Date (Phoenix dactylifera L.) seeds are available in bulk quantities after manufacturing pitted dates or syrup considered as waste stream.

Bemisia tabaci is an important agricultural pest with worldwide distribution and host preference. Therefore, understanding the biology of this pest is important to devise specific pest control strategies. The antennae of herbivorous insects play an important role in the identification of hosts using plant volatiles. To understand the features of antennae in B. tabaci MEAM 1(formerly known as bi...

Atomic force microscopy has been applied to an acrylate polymer microarray to achieve a full topographic characterisation. This process discovered a small number of hydro-responsive materials created from monomers with disparate hydrophilicities that show reversibility between pitted and protruding nanoscale topographies.

"Medicalized" weapons--those that rely on advances in neuroscience, physiology, and pharmacology--offer the prospect of reducing casualties and protecting civilians. They could be especially useful in modern asymmetric wars in which conventional states are pitted against guerrilla or insurgent forces. But may physicians and other medical workers participate in their development?
