    Background. A mother who has generally to give an increasing food before a baby has 6 month old, there is difficult to understand a new feed method which it’s more healthy. While this fact can annoyance the healthy of baby and the frequentations of visiting to the healthy servant is often more. Objective. This research to tendency to know a relation an increasing feeding at younger old with phase of visiting to healthy servant. Methods. Type of the research is observational of research which us a correlation kind for looking a condition objectively. The research has done in Sine Sragen with taking sample to 48 of baby at 6-12 months old. A total sampling method was used to take and interview. The data, then, was analyzed by using a nonparametric statistic, a bivariate technique, namely, with correlation analysis of Rank Spearman. Conclusions. Results of the research indicated that: (1) Increasing feed method for a baby at 6-12 months old in Sine Sragen that base done the research results is look in that an increasing feed except ASI was gift although the age of baby is not 6 month complete and there is often gift although a baby was suckled. (2) A baby with 6-12 months old in Sine is often visited to the healthy servant. A visiting to the healthy servant at is come in to often category that is 26 person, and than precisely category is 18 person, and rarely category is 4 person. High frequentation of visiting to the healthy servant because an often of the children have a diseases like diarrhea, allergic, or difficult to defecate. (3) From bivariate analysis with correlation equation, a correlation coefficient value of 0,575 was obtained with tcalculation > ttable (6,832 > 2,042) at significance level of 5%. It’s mean there is a positive relation that significance between an increasing feed at younger old with the level of visiting to the healthy servant. An increasing feeding that so early will make a healthy disturbing to the baby in other day

    All "static" spherically symmetric perfect fluid solutions of Einstein's equations with constant equation of state parameter and finite-polynomial "mass function"

    We look for "static" spherically symmetric solutions of Einstein's Equations for perfect fluid source with equation of state p=wρp=w\rho. In order to include the possibilities of recently popularized dark energy and phantom energy possibly pervading the spacetime, we put no constraints on the constant ww. We consider all four cases compatible with the standard ansatz for the line element, discussed in previous work. For each case we derive the equation obeyed by the mass function or its analogs. For these equations, we find {\em all} finite-polynomial solutions, including possible negative powers. For the standard case, we find no significantly new solutions, but show that one solution is a static phantom solution, another a black hole-like solution. For the dynamic and/or tachyonic cases we find, among others, dynamic and static tachyonic solutions, a Kantowski-Sachs (KS) class phantom solution, another KS-class solution for dark energy, and a second black hole-like solution. The black hole-like solutions feature segregated normal and tachyonic matter, consistent with the assertion of previous work. In the first black hole-like solution, tachyonic matter is inside the horizon, in the second, outside. The static phantom solution, a limit of an old one, is surprising at first, since phantom energy is usually associated with super-exponential expansion. The KS-phantom solution stands out since its "mass function" is a ninth order polynomial.Comment: 24 standard LaTeX pages, 4 tables, no figures. -Title changed to avoid equation in title. -The set of solutions and their interpretation remains unchanged, but new classification of solutions (solution labels also changed), consolidation of appendix into a table (omitting calculation details) resulted in shorter paper. -Updated Publication info for preprints in Reference

    Efficient Monte Carlo Methods for Cyclic Peptides

    Full text link
    We present a new, biased Monte Carlo scheme for simulating complex, cyclic peptides. Backbone atoms are equilibrated with a biased rebridging scheme, and side-chain atoms are equilibrated with a look-ahead configurational bias Monte Carlo. Parallel tempering is shown to be an important ingredient in the construction of an efficient approach.Comment: LaTeX source, 10 EPS figures, to appear in Molecular Physic

    Matter fields from a decaying background Lambda vacuum

    Full text link
    We suggest an alternative framework for interpreting the current state of the visible universe. Our approach is based on a dynamical ``Cosmological Constant'' and the starting point is that a decaying vacuum produces matter. As we point out, such a dynamical Lambda is not incompatible with the general requirements of general relativity. By assuming inflation and big bang nucleosynthesis we can solve for the present fractional densities of matter Omega_{m,0} and vacuum Omega_{Lambda, 0} in terms of only one parameter which we call the vacuum domination crossing redshift, z_c. We put constraints on z_c to obtain a universe that is presently vacuum dominated and with characteristic densities consistent with observations. The model points to the possible existence of newly formed dark matter in the inter-cluster voids. We argue that some of this matter could be accreting onto clusters through the latter's long range gravitational potentials. If so, then cluster dark matter halos may not manifest clear cut-offs in their radial density profiles. Furthermore, if a substantial amount of this newly produced matter has already drained onto the clusters, then the CMB power spectrum may favor lower dark matter density values than is currently observed bound in the clusters. A final feature of our approach relates to the combined effect of the matter production by a decaying vacuum and the different rates at which matter and the vacuum will dilute with the scale factor. Such combination may create conditions for a universe in which the vacuum and matter densities dilute and evolve towards comparable amplitudes. In this sense the model offers a natural and conceptually simple explanation to the Coincidence Problem.Comment: 22 pages, 1 figure, accepted for publication in Int. J. Mod. Phys. Lett.

    Look-up Tables to Link 1991 Population Statistics to the 1998 Local Government Areas

    Between 1995 and 1998 the local authority structure and geography of the United Kingdom was substantially revised. The two-tier system of local government was abolished in Wales, Scotland, and in parts of non-metropolitan England, and replaced with a single-tier system. This involved the creation of a new set of local authority area boundaries which in many places cut across those of the old districts. In addition, many of the local authorities unaffected by the reorganisation nonetheless had experienced small - though demographically significant - boundary changes since the last census. By the time the final phase of the reorganisation came into effect on 1st April 1998 the local government map of the United Kingdom was very different from that of April 1991. There is a need therefore to provide demographic and other geographically based data for the new geography for years prior to 1998. This paper aims to fill a part of this requirement by focusing on two important issues. First, it describes a look-up table detailing exactly how the 1998 local government geography relates to 1991 Census areas, and second, it sets out methods for producing 1991 Census data and mid-1991 population estimates (including single year age detail) for the new geography. A selection of the results produced by the described methods is included in tables and population pyramids

    If Archimedes would have known functions

    Full text link
    These are notes and slides from a Pecha-Kucha talk given on March 6, 2013. The presentation tinkered with the question whether calculus on graphs could have emerged by the time of Archimedes, if the concept of a function would have been available 2300 years ago. The text first attempts to boil down discrete single and multivariable calculus to one page each, then presents the slides with additional remarks and finally includes 40 "calculus problems" in a discrete or so-called 'quantum calculus' setting. We also added some sample Mathematica code, gave a short overview over the emergence of the function concept in calculus and included comments on the development of calculus textbooks over time.Comment: 31 pages, 36 figure

    Chiral SUSY Theories with a Suppressed SUSY Charge

    Get PDF
    The well-known Chiral and Gauge SUSY Actions realize the SUSY charge in terms of transformations among the Fields. These transformations are included in the Master Equation by coupling them to Sources. Here we show that there are new local SUSY Actions where the Chiral SUSY transformations are realized in terms of transformations among both Fields and Sources. These Actions can be easily obtained from the Chiral case by a very simple and local `Exchange Transformation', which carries along all the interactions without difficulty. For these new SUSY Actions, the SUSY charge does not exist in the relevant sector, because Sources do not satisfy Equations of Motion. Nevertheless, the `Exchange Transformation' ensures that the new Master Equation is true for the new Action. As a consequence, the Master Equation also is true for the new 1PI Generating Functional. This implies that a `Suppressed SUSY Charge' version of SUSY is still present. SUSY certainly becomes more obscure and less constrained in this case. But it is still very restrictive. The new theories can be obtained from the old theories by using a special technique, but it is not true that they are a sort of `broken version of supersymmetry'. They are simply a new type of theory that is governed by Supersymmetry, but without the use of Supercharges (except perhaps in some sectors). In particular the number of physical Bosonic and Fermionic degrees of Freedom are not equal for these new (sub)-Actions, although there is still Boson/Fermion mass degeneracy in a (sub)-Action, so long as there is still a Boson present. Notably, there is even a SUSY (sub)-Action where the physical Scalars are not present, so that the (sub)-Action contains physical Fermions only. In this theory the degeneracy of Bosonic and Fermionic masses is obviously not present.Comment: 21 pages This version has a better explanation of how and why these new representations of SUSY can and do exist, without contradicting the known results in SUSY theor
