In graph pegging, we view each vertex of a graph as a hole into which a peg can be placed, with checker-like “pegging moves” allowed. Motivated by well-studied questions in graph pebbling, we introduce two pegging quantities. The pegging number (respectively, the optimal pegging number) of a graph is the minimum number of pegs such that for every… (More)

OBJECTIVE
The aim of this study was to evaluate the overall and progression-free survival of papillary thyroid carcinoma (PTC), comparing the American Thyroid Association (ATA) guideline for risk of recurrence with the TNM staging system with dynamic assessment at 2 years.
PATIENTS AND METHODS
This study is a retrospective analysis of 689 PTC patients… (More)

OBJECTIVE
To evaluate the overall and progression-free survival for follicular thyroid carcinoma (FTC) based on the American Thyroid Association (ATA) staging system for recurrence risk assessment and the TNM staging system.
METHODS
A clinical review of FTC patients between 1995 and 2014 was conducted at a single center. The data was classified using the… (More)

We consider relationships between families of K3 surfaces, in the context of string theory. An important ingredient of string theory also of interest in algebraic geometry is T-duality. Donagi and Pantev [DP] have extended the original duality on genus one fibred K3 surfaces with a section to the case of any genus one fibration, via a Fourier-Mukai… (More)

Melorheostosis is a benign, noninheritable bone dysplasia characterized by its classic radiographic features of dense, flowing hyperostosis. It frequently affects one limb, usually the lower extremity and rarely the axial skeleton. A 26-year-old lady with obesity, polycystic ovarian syndrome and scalp dandruff presented with a long standing history of upper… (More)

Let X be a K3 surface of degree 8 in P with hyperplane section H . Given X we can associate to it another K3 surface M which is a double cover of P ramified on a sextic curve C. We study the relation between M and the moduli space M of rank two vector bundles on X with Chern classes c1 = H and c2 = 4 We build on previous work of Mukai and others, giving… (More)

We study Lagrangian points on smooth holomorphic curves in TP equipped with a natural neutral Kähler structure, and prove that they must form real curves. By virtue of the identification of TP with the space L(E) of oriented affine lines in Euclidean 3-space E, these Lagrangian curves give rise to ruled surfaces in E, which we prove have zero Gauss… (More)
