Wormlike chain or tense string ? A question of resolution
It is shown that a wormlike chain, i.e., a filament with a fixed contour-length ¯ S and a bending elasticity κ, attached to a frame of length L, can be described—at low resolutions—by the same type of elastic free-energy as a tense string. The corresponding tension is calculated as a function of temperature, L, κ and ¯ S. Elastic free-energies are used to describe the distorted states and fluct...
متن کاملThe Meaning of Eros/macho
Most of the mass density in the Universe—and in the halo of our own galaxy—exists in the form of dark matter. Overall, the contribution of luminous matter (in stars) to the mass density of the Universe is less than 1%; primordial nucleosynthesis indicates that baryons contribute between 1% and 10% of the critical density (0.01h <∼ ΩB <∼ 0.02h; h = the Hubble constant in units of 100 km sMpc); a...
متن کاملDEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کاملThe Reality of Tense
I argue for a version of tense-logical realism that privileges tensed facts without privileging any particular temporal standpoint from which they obtain. Is reality somehow tensed? Or is tense a feature of how we represent reality and not properly a feature of reality itself? Although this question is often raised, it is very hard to say what it comes to. For both sides to the debate can agree...
متن کاملAnnotating "tense" in a Tense-less Language
In the context of Natural Language Processing, annotation is about recovering implicit information that is useful for natural language applications. In this paper we describe a “tense” annotation task for Chinese, a language that does not have grammatical tense, that is designed to infer the temporal location of a situation in relation to the temporal deixis, the moment of speech. If successful...
