Many people are experienced in measuring radiation dose from photons and electrons. These two forms of radiation involve similar measurements since it is secondary electrons produced by the photons which actuallv deliver the dose. The electron is a light charged particle. Relatively fewer people have experience in measuring neutron dose. The neutron is a heavy uncharged particle. It has nearly ...

Cancer Immunity (15 January 2013) 13: 2

Apoptotic cells are significantly more immunogenic than necrotic cells, even though both forms are identical in antigenic content. When a combination of apoptotic and necrotic cells are used to immunize, the phenotype conferred by apoptotic cells, i.e., high immunogenicity, is dominant. However, necrotic cells are not immunosuppressive or tolerogenic. Apoptotic and necrotic cells are taken up b...

Lecture 19 — November 15 , 2012

In the last lecture, we saw the graph powering method, which allows us to increase the soundness gap but has the drawback of increasing the alphabet size from |Σ| to |Σ|dt (where |Σ| is a constant). In this lecture, we describe how to reduce the alphabet size (from |Σ|dt back to |Σ|), while causing only a small decrease in the gap (and a constant factor increase in the constraint graph size). T...
