Ideals of equations for elements in a free group and Stallings folding [PDF]
, 2022 Let $F$ be a finitely generated free group and let $H\le F$ be a finitely generated subgroup. Given an element $g\in F$, we study the ideal $\mathfrak{I}_g$ of equations for $g$ with coefficients in $H$, i.e. the elements $w(x)\in H*\langle x\rangle$ such that $w(g)=1$ in $F$. The ideal $\mathfrak{I}_g$ is a normal subgroup of $H*\langle x\rangle$, and

Intestinal Ascaris lumbricoides [PDF]
Pediatric Radiology, 2009 A 12-year-old boy from Pakistan presented with abdominal pain. A US showed a long, curvilinear, peristaltic structure located within the distal small bowel. Longitudinal scans of the structure demonstrated two parallel outer echogenic lines (arrows) separated by a hypoechoic region (Fig. 1). Transverse view shows a target-like appearance (arrows) (Fig.

Effect of urban vs. rural residence on the association between atopy and wheeze in Latin America: findings from a case-control analysis. [PDF]
, 2014 BACKGROUND: The association between atopy and asthma is attenuated in non-affluent populations, an effect that may be explained by childhood infections such as geohelminths.

A fine property of Whitehead's algorithm [PDF]
arXiv, 2021 We develop a refinement of Whitehead's algorithm for primitive words in a free group. We generalize to subgroups, establishing a strengthened version of Whitehead's algorithm for free factors. We make use of these refinements in proving new results about primitive elements and free factors in a free group.

Characterization of Ascaris from Ecuador and Zanzibar [PDF]
, 2014 To shed light on the epidemiology of ascariasis in Ecuador and Zanzibar, 177 adult worms retrieved by chemo-expulsion from either people or pigs were collected, measured and subjected to polymerase chain reaction-restriction fragment length polymorphism (
