The necessary and sufficient conditions of similarity of two idempotent matrices are proved, the idempotency of linear combinations of two idempotent matrices is discussed.
Despite a high morphological similarity, tumors with allelic loss on the short arm of chromosome 1 (1pLOH) are more chemosensitive than those without 1pLOH.
The community has an outstanding dominant species and the arborous layer possesses a comparatively high diversity index.The similarity is rather striking among different quadrats species.
They share sequence homology and show sequence similarity 89.1% and 70.1% to the LTR of rice retrotransposon RIRE8, respectively.SLTR1 and SLTR2 are of gypsy retrotransposons of rice.
Several distinct rickettsiae (a parasite carried by ticks, fleas, and lice) cause a disease known as typhus in humans.All cause disease with similarities of fever, headache, and rash.
