AN UNUSUAL MASS OF THE CHEST WALL IN A 7 YEARS OLD CHILD: AN ASKIN'S TUMOUR

Journal of Cancer and Allied Specialties, 2018
Askin’s tumour is a primitive neuroectodermal tumour developing from the soft tissues of the chest wall. It is commonly misdiagnosed due to features similar to other round blue cell tumours.

Finding alike supercells of two crystals

Science and Technology of Advanced Materials: Methods, 2023
An algorithm is proposed that finds supercells of two arbitrary crystals that are ‘alike’, or in other words, have almost the same lattice parameters. The given input is the primitive cells of two crystals, crystal 1 and 2, and their supercell sizes, N ...

Growth of Primitive Elements in Free Groups

, 2014
In the free group $F_k$, an element is said to be primitive if it belongs to a free generating set. In this paper, we describe what a generic primitive element looks like.

Primitive digraphs with large exponents and slowly synchronizing automata [PDF]

, 2013
We present several infinite series of synchronizing automata for which the minimum length of reset words is close to the square of the number of states.

ASMs and Operational Algorithmic Completeness of Lambda Calculus [PDF]

, 2010
We show that lambda calculus is a computation model which can step by step simulate any sequential deterministic algorithm for any computable function over integers or words or any datatype.

On the Structure of Bispecial Sturmian Words

, 2013
A balanced word is one in which any two factors of the same length contain the same number of each letter of the alphabet up to one. Finite binary balanced words are called Sturmian words.

A Characterization of Bispecial Sturmian Words

, 2012
A finite Sturmian word w over the alphabet {a,b} is left special (resp. right special) if aw and bw (resp. wa and wb) are both Sturmian words. A bispecial Sturmian word is a Sturmian word that is both left and right special. We show as a main result that

Statistics of reduced words in locally free and braid groups: Abstract studies and application to ballistic growth model

, 1997
We study numerically and analytically the average length of reduced (primitive) words in so-called locally free and braid groups. We consider the situations when the letters in the initial words are drawn either without or with correlations.
