In this paper the properties of node-node adjacency matrix in acyclic digraphs are considered. It is shown that topological ordering and node-node adjacency matrix are closely related. In fact, first the one to one correspondence between upper triangularity of node-node adjacency matrix and existence of directed cycles in digraphs is proved and then with this correspondence other properties of ...

Dear Sir,?Some years agOj wlien at the General Hospital, Allahabad, I had occasion to destroy a monkey, (a common brown one), and for this purpose I selected hydrocyanic acid. Having had the monkey's month opened, about a drachm, or so, of the hydrocyanic acid was poured from the bottle into his pharynx ; but, to my great surprise, without any fatal effect. The monkey fell down in a semi-insens...

Given a local quantum field theory net A on the de Sitter spacetime dS, where geodesic observers are thermalized at Gibbons-Hawking temperature, we look for observers that feel to be in a ground state, i.e. particle evolutions with positive generator, providing a sort of converse to the HawkingUnruh effect. Such positive energy evolutions always exist as noncommutative flows, but have only a pa...

Service. In an article published on the 12th instant, it complains in bitter terms of the conduct of the authorities, and quotes many passages from your " leader" on the question, in support of its views. The Lancet, on the contrary, by some perversity of intelligence, looks at the matter in quite an opposite light, and has actually approved of the new Warrant as one calculated to be of benefit...

We model a general choice environment via probabilistic choice correspondences, with (possibly) incomplete domain and infinite universal set of alternatives. We offer a consistency restriction regarding choice when the feasible set contracts. This condition, ‘contraction consistency’, subsumes earlier notions such as Chernoff’s Condition, Sen’s α and β , and regularity. We identify a restrictio...

object of course is to tempt as many innocent persons as possible to enrol their names as subscribers. It is usual to send the first number of the new year's issue to every medical man iu the kingdom, and this is another incentive to " publishing" enterprise. This year, however, the only journals distributed gratis were the Medical Times and Gazette and the British Medical Journal; and of1 thes...

a banquetting room, has witnessed, during the past year, an amount of hospitality previously unknown within the college walls. In it, on the 26th of February, the President entertained the Lord Lieutenant and a number of other guests at dinner; and on the 5th of March, Dr. J. Brady, M.p.} who had that day been presented with an honorary diploma of fellowship by the college, dined in it as the g...
