Mitochondrial DNA invariability also suggests recent radiation of these clades, probably within the last 200,000 years. These findings are consistent with the Pleistocene refugia hypothesis: in the late Pleistocene epoch, climate change reduced once widespread habitable forest areas, resulting in allopatric speciation.

An important feature of the definition of the DOS is that it can be extended to any system. One of its properties are the translationally invariability which means that the density of the states is homogeneous and it's the same at each point of the system. But this is just a particular case and the LDOS gives a wider description with a heterogeneous density of states through the system.

202 and frequently discussed Christianity with the Swiss astronomer Jean-Frédéric-Théodore Maurice.Hahn (2005), pp. 202, 233 He told Maurice that "Christianity is quite a beautiful thing" and praised its civilising influence. Maurice thought that the basis of Laplace's beliefs was, little by little, being modified, but that he held fast to his conviction that the invariability of the laws of nature did not permit of supernatural events.

Read January 13, 1825. [Phil. Trans. 1825, p. 147.] His collimator was meant to replace a level, or plumb-line, in astronomical observations, and to furnish a ready and perfectly exact method of determining the position of the horizontal or zenith point on the limb of a circle or zenith sector. Its principle is the invariability, with respect to the horizon, of the position assumed by any body of invariable figure and weight floating on a fluid.

A cause is defined as an unconditional and invariable antecedent of an effect and an effect as an unconditional and invariable consequent of a cause. The same cause produces the same effect; and the same effect is produced by the same cause. The cause is not present in any hidden form whatsoever in its effect. The following conditions should be met: # The cause must be antecedent [Purvavrtti] # Invariability [Niyatapurvavrtti] # Unconditionality [Ananyathasiddha] Nyaya recognizes five kinds of accidental antecedents [Anyathasiddha] # Mere accidental antecedent. E.g.

The Eastern Eucharists of whatever rite are marked by the invariability of the priest's part. There are, it is true, alternative anaphoras which are used either ad libitum, as in the Syro-Jacobite Rite, or on certain days, as in Byzantine and East Syrian, but they are complete in themselves and do not contain passages appropriate to the day. The lections of course vary with the day in all rites, and varying antiphons, troparia, etc., are sung by the choir; but the priest's part remains fixed.

An AAGPBL scout signed Shollenberger after seeing her play in an amateur softball league in Hamburg. She entered the league in 1946 with the Kenosha Comets, playing for them five years before joining the Kalamazoo Lassies (1952-'54). While the Comets were invariability low in the standings, their fielding was always among the best in the league, and Shollenberger was one of the key reasons. In her rookie season, she posted a .225 batting average with 35 runs, 24 runs batted in, and 35 stolen bases in 94 games.

In general, AMA style strives for clarity and simplicity, and trusts the target readership to have a certain amount of knowledge and education. For example, AMA style dispenses with periods in abbreviations, on the grounds that they are unnecessary for meaning's or clarity's sake in all but very few contexts. AMA also requires expansion of most abbreviations at first use, for clarity's sake. The AMA Manual of Style sets standards for mechanical style, but does not insist on invariability for its own sake in contexts where a bit of limited variation is logical, especially in higher- level style.

Noam Chomsky cites as evidence for this theory, the apparent invariability, according to his views, of human languages at a fundamental level. In this way, linguistics may provide a window into the human mind, and establish scientific theories of innateness which otherwise would remain merely speculative. One implication of Noam Chomsky's innatism, if correct, is that at least a part of human knowledge consists in cognitive predispositions, which are triggered and developed by the environment, but not determined by it. Chomsky suggests that we can look at how a belief is acquired as an input- output situation.

After graduation, Haret won a scholarship competition organized by Titu Maiorescu and went to Paris in order to study mathematics at the Sorbonne. There he earned a mathematics diploma in 1875 and a physics diploma in 1876. Two years later (on 18 January 1878) he earned his Ph.D. by defending his thesis, Sur l’invariabilité des grandes axes des orbites planétaires (On the invariability of the major axis of planetary orbits), in front of examiners led by Victor Puiseux. In this work he proved a result fundamental for the n-body problem in astronomy, the thesis being published in Vol.

The French doctor Charles Anglada (1809–1878) wrote a book in 1869 on extinct and new diseases. He did not distinguish infectious diseases from others (he uses the terms reactive and affective diseases, to mean diseases with an external or internal cause, more or less meaning diseases with or without an observable external cause). He writes in the introduction > A widely held opinion among physicians admits the invariability of > pathologies. All the illnesses which have existed or which have an outbreak > around us are categorized according to arrested and preconceived types, and > must enter one way or the other into the frameworks established by the > nosologists.

Table 2 summarizes some qualitative features of this kind of long-range transfer and of some more or less trivial mechanisms. The non-trivial transfer differs from re-absorption transfer by its independence of the volume of the solution, by the decrease in sensitizer fluorescence lifetime, and by the invariability of the sensitizer fluorescence spectrum. It differs from short-distance collisional transfer by its independence of solvent viscosity and from transfer within a molecular complex by the constancy of absorption spectra and the decrease in sensitizer fluorescence lifetime. In most cases, some of these different properties allow a decision between trivial and non-trivial transfer mechanisms.

There is often confusion about the two different concepts of collective noun and mass noun. Generally, collective nouns are not mass nouns, but rather are a special subset of count nouns. However, the term "collective noun" is often used to mean "mass noun" (even in some dictionaries), because users conflate two different kinds of verb number invariability: (a) that seen with mass nouns such as "water" or "furniture", with which only singular verb forms are used because the constituent matter is grammatically nondiscrete (although it may ["water"] or may not ["furniture"] be etically nondiscrete); and (b) that seen with collective nouns, which is the result of the metonymical shift between the group and its (both grammatically and etically) discrete constituents. Some words, including "mathematics" and "physics", have developed true mass- noun senses despite having grown from count-noun roots.
