Heredity of roaring?

The larynx of roaring and non-roaring cats.

Dissections were made of the larynges of 14 species of the cat family, with representative specimens from all genera. It was found that the vocal folds of the larynx of genus Panthera (with the exception of the snow leopard) form the basic structure of a sound generator well-designed to produce a high acoustical energy. Combined with an efficient sound radiator (vocal tract) that can be adjuste...

Better bitmap performance with Roaring bitmaps

Bitmap indexes are commonly used in databases and search engines. By exploiting bit-level parallelism, they can significantly accelerate queries. However, they can use much memory, and thus we might prefer compressed bitmap indexes. Following Oracle’s lead, bitmaps are often compressed using run-length encoding (RLE). Building on prior work, we introduce the Roaring compressed bitmap format: it...

Some Aspects of Heredity

Hologynic Heredity.

Sex-linked characters in man are well known; they are all pathological characters, so far as known; they are transmitted according to the same laws as the sex-linked characters in the little fruit-fly (Drosophila) and explained in the same manner by means of the sex chromosome. I propose the name “diagynic heredity” for this kind of heredity, as the sex-linked character is transmitted from male...
