Abelian complexity of a word u is a function that counts the number of pairwise non-abelian-equivalent factors of u of length n. We prove that for any c-balanced Parry word u, the values of the abelian complexity function can be computed by a finite-state automaton. The proof is based on the notion of relative Parikh vectors. The approach works for any function F (n) that can be expressed in te...

Parry-Romberg syndrome, also known as progressive hemifacial atrophy, is a rare disorder characterized by slow and progressive hemifacial atrophy. The treatment offered for the syndrome generally aims at improving aesthetics. Fat grafts, silicone injections or acrylic prosthesis are alternatives suggested for correction of facial atrophy. Currently, the recommended technique for correction of f...

Dr. Parry's Elements of Pathology and Therapeutics. ( Continued from page 159. ) TV E shall pass entirely over two sections in our author's work?one on the structure and functions of the Nervous System ; the other on the Mental Faculties. In the first are many accurate and ingenious anatomical remarks, tho' we think he has eulogised rather too highly, Messrs. Gall and Spurzheim. In the second, ...

China is gearing up to supply the world with affordable vaccines that fulfil all efficacy, safety and quality requirements. Jane Parry reports.

The common anaemia in premature infants is iron deficiency anaemia, but megaloblastic anaemia can also occur and here we report three such cases. Our interest in megaloblastic anaemia was stimulated by a recent case in which megaloblastic anaemia developed when a low phenylalanine diet was being given for treatment of phenylketonuria (Royston and Parry, 1962). In the discussion of this paper Ro...
