We construct embedded closed minimal surfaces in the round three-sphere S(1), resembling two parallel copies of the Clifford torus, joined by m small catenoidal bridges symmetrically arranged along a square lattice of points on the torus.

Identifying the precise locus of general cognitive ability (g) in the flow of information between perception and action is an important goal of differential psychology. To localize the negative correlation between g and reaction time to a specific processing stage, we administered a speeded number-comparison task to two groups differing in average g. The participants had to respond to two stimu...

Human and animal studies have revealed a strong association between periconceptional environmental factors, such as poor maternal diet, and an increased propensity for cardiovascular and metabolic disease in adult offspring. Previously, we reported cardiovascular and physiological effects of maternal low protein diet (LPD) fed during discrete periods of periconceptional development on 6-month-o...

We construct quasiconformal mappings in Euclidean spaces by integration of a discontinuous kernel against doubling measures with suitable decay. The differentials of mappings that arise in this way satisfy an isotropic form of the doubling condition. We prove that this isotropic doubling condition is satisfied by the distance functions of certain fractal sets. Finally, we construct an isotropic...

INTRODUCTION In order to identify targets for primary preventive strategies, we explored possible predictors of periconceptional folic acid (pFA) intake in a Nigerian population of reproductively active women. METHODS A cross sectional study of mothers attending immunization clinics at two hospitals was conducted between May and November 2012. Information obtained included sociodemographic an...

BACKGROUND Although periconceptional glycemic control directly impacts perinatal outcome for pregestational diabetic women, these women still frequently enter pregnancy with suboptimal control of glycemia. OBJECTIVES To determine how frequently diabetic women enter pregnancy with suboptimal glycemic control and to identify factors associated with not achieving optimal periconceptual control o...
