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 . 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 . 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

Efficient Monte Carlo Methods for Cyclic Peptides
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
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.

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
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
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
