چکیده
The continuous deformation of any spherical isometric folding into the standard spherical folding, , s f defined by ( ) ( ) , , , , , z y x z y x fs = remains an open problem since 1989. We show that this conjecture is restricted to the class of primitive foldings and it is exhibited a spherical folding within this class, where the difficulty of deformation is evidenced.

A note on Fouquet-Vanherpe’s question and Fulkerson conjecture
The excessive index of a bridgeless cubic graph $G$ is the least integer $k$, such that $G$ can be covered by $k$ perfect matchings. An equivalent form of Fulkerson conjecture (due to Berge) is that every bridgeless cubic graph has excessive index at most five. Clearly, Petersen graph is a cyclically 4-edge-connected snark with excessive index at least 5, so Fouquet and Vanherpe as...
متن کاملA Further Note on Runs in Independent Sequences
Given a sequence of letters generated independently from a finite alphabet, we consider the case when more than one, but not all, letters are generated with the highest probability. The length of the longest run of any of these letters is shown to be one greater than the length of the longest run in a particular state of an associated Markov chain. Using results of Foulser and Karlin (19...
متن کاملIt’s Not About The Biceps
In the biomedical paradigm all symptoms and limitations are ascribed to discrete pathophysiology. However, abiopsychosocial health model that accounts for the important influence of mind-set and circumstances on illness maybe preferable in the vast majority of cases. Some of the shortcomings of the biomedical model include an overrelianceon tests and treatments. One major issue of the biomedica...
متن کاملWiener Way to Dimensionality
This note introduces a new general conjecture correlating the dimensionality dT of an infinite lattice with N nodes to the asymptotic value of its Wiener Index W(N). In the limit of large N the general asymptotic behavior W(N)≈Ns is proposed, where the exponent s and dT are related by the conjectured formula s=2+1/dT allowing a new definition of dimensionality dW=(s-2)-1. Being related to the t...
