Complement lysis: a hole is a hole

Immunology Today, 1991
recent experimental advances 21, it is now possible to produce MACs with a precise molecular composition 7 for better designed experiments. In my judgement, however, it will always be problematic to propose a single unifying mechanism for MAC action simply because MAC effects are not uniform. The reason for attempting to classify MACs as leaky patch or

The Cinderella Game on Holes and Anti-holes

2011
We investigate a two-player game on graphs, where one player (Cinderella) wants to keep the behavior of an underlying water-bucket system stable whereas the other player (the wicked Stepmother) wants to cause overflows. The bucket number of a graph G is the smallest possible bucket size with which Cinderella can win the game.

Hole dephasing caused by hole–hole interaction in a multilayered black phosphorus

Journal of Physics: Condensed Matter, 2017
We study the magnetotransport of holes in a multilayered black phosphorus in a temperature range of 1.9 to 21.5 K. We observed a negative magnetoresistance at magnetic fields up to 1.5 T. This negative magetoresistance was analyzed by weak localization theory in diffusive regime.

HOLE-HOLE CORRELATIONS IN THE 2D HUBBARD MODEL

International Journal of Modern Physics B, 1991
The hole-hole correlation function in the 2D Hubbard model is investigated in the low doping regime both via Monte Carlo simulations for U=4 and Lanczos diagonalization on a 16 site cluster for very large U. The results are compared with available theoretical predictions for the strong coupling limit.

Dumb holes: analogues for black holes

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2008
The use of sonic analogues to black and white holes, called dumb or deaf holes, to understand the particle production by black holes is reviewed. The results suggest that the black hole particle production is a low-frequency and low-wavenumber process.

The shape of holes

Cognition, 2003
The shape of holes can be recognized as accurately as the shape of objects (Palmer, S. E. (1999). Vision science: photons to phenomenology. Cambridge, MA: MIT Press), yet the area enclosed by a hole is a background region, and it can be demonstrated that background regions are not represented as having shape.

Macular holes

Ophthalmology Clinics of North America, 2002
Spontaneous closure of macular holes occurs in 3% to 9% of patients over 6 years [3,58]. Visual acuity can recover dramatically once the hole closes. The risk for hole development in the fellow eye in the absence of PVD is approximately 29%. The presence of vitreomacular separation reduces the risk to less than 5%.
