Recursions for
Let A_n = (1,0,1,0,\dots ) be the alternating word of length n starting with 1. (By symmetry, probabilities for alternating words starting with 0 are the same as for A_n.) In this section, we first compute the v_n given in (REF ), and then we prove Theorem 1(a). The computation of v_n is done recursively; the recursion...

For example, if M=5, the larger root of f is .9978\dots .A Bernoulli sequence Y contributing to v_{n,k} must satisfy Y_k=1, and the preceding sequence (Y_1,\dots ,Y_{k-1}) cannot contain 1 and 0 in that order, since if it did, there would be an admissible embedding starting before position k.

Relations to the spacing random variables
In this section, we prove several results relating M-seen finite words to inequalities satisfied by the spacing variables \tau _k and their partial sums. When the word is either constant or alternating, these are equivalences, and were stated as Theorem REF in the Introduction. For general words, we only have one direc...

Abstract
We are interested in knowing what type of manifolds are obtained by doing Dehn surgery on closed pure 3-braids in the 3-sphere. In particular, we want to determine when we get the 3-sphere by surgery on such a link. We consider links which are small closed pure 3-braids; these are the closure of 3-braids of the form $(...

Abstract
The logarithmic Sobolev inequality for the Hamming cube {0,1}^n states that for any real-valued function f on the cube holds E(f,f) \ge 2 Ent(f^2), where E(f,f) is the appropriate Dirichlet form (also known as "sum of influences"). We show that the constant C = 2 at the right hand side of this inequality can be replac...

Isoperimetric problems on the Hamming cube
This paper deals with discrete isoperimetric inequalities on graphs. Let a graph G = (V,E) be given, and let A \subseteq V be a set of vertices in G. An isoperimetric inequality addresses the question of how small the boundary \partial A of A can be, given the cardinality of A, by lower bounding the size of \partial A ...

Abstract
The production of prompt photons at high energies provides a direct probe of the dynamics of the strong interactions. In particular, one expect that it could be used to constrain the behavior of the nuclear gluon distribution in $pA$ and $AA$ collisions. In this letter we investigate the influence of nuclear effects in...

The same happens for the HKN one in this limit, but this growth starts only at x>10^{-2}, with R_g being flat for 10^{-5}<x< 10^{-2}. At x\approx 10^{-1}, we have that behaviors predicted by the EKS and EPS parameterizations are similar, with R_g exceeding 1.2. The main distinction between these parameterizations is th...

From these results we can conclude that the study of the ratio R_{pA} at RHIC can be useful to determine the presence or not of the antishadowing and constrain its magnitude. On the other hand, at LHC energies all parameterizations predict a ratio smaller than one, with the suppression directly associated to the magnit...

Topological definition of saddles
We start by introducing the notion of a gate between two sets A and B. Roughly speaking, a gate is a set that cannot be avoided by those paths going from A to B which stay as low as possible in the potential landscape. Saddles will then be defined as particular points in gates.It is useful to introduce some terminology...

The near threshold production of K+K- pairs in proton-proton collisions has been investigated at the cooler synchrotron COSY below and above the threshold for the $\phi$ meson using the COSY-11 and ANKE facilities, respectively. The excitation function determined for the pp-->ppK+K- reaction revealed a statistically si...

Introduction
A primary motivation for measuring cross sections for the pp\rightarrow ppK^{+}K^{-} reaction near the kinematical threshold was the study of the hadronic interaction between K^{+} and K^{-} mesons in order to understand the structure of the scalar resonances f_{0}(980) and a_{0}(980) . Such measurements have been made...

Goldhaber plot analysis: generalization of the Dalitz plot for four particle final state
Usage of the Dalitz plot for extracting information about the interaction among particles in the case of three body final states is well known.

We obtain the lattice Green's function via Eq. (5). Even though the DF method is an approximate method, it considers not only the short range but also the long range correlations. Moreover, the calculation of the two-particle properties does not introduce serious computational burden and fermionic sign problem.

SCA method
At high temperature the Monte carlo integration over the auxillary classical field \phi (\tau ) can be approximated by assuming \phi (\tau )\approx const. This approximation is useful because it allows to check the QMC results at temperature quickly. In this part we introduce the SCA method , as impruity solver for DC...

SCA method
By a Grassmann integration we can rewrite the partition function which is represented as a four-dimensional integration in terms of \phi _j and the fermionic Matsubara frequency.Z=\int d{\vec{\phi _{j} }}e^{-S_{eff}[{\bf a}(i\omega ),\phi _{j}]},where the effective action S_{eff}=\beta V is defined byV(\vec{\phi })=\fr...

CT QMC method
Here we describe the CT QMC method . The starting point is action can be split into an unperturbed action S_0 and an interaction part W. By Taylor expansion of partition function in powers of the interaction U, we can reexpress the partition functionZ=\sum _{k,\sigma }Z_0 \frac{(-U)^k}{k!}\int dr_{1\sigma } \dots dr_{k...
