Sub-second temporal magnetic field microscopy using quantum defects in diamond.

Wide field-of-view magnetic field microscopy has been realised by probing shifts in optically detected magnetic resonance (ODMR) spectrum of Nitrogen Vacancy (NV) defect centers in diamond. However, these widefield diamond NV magnetometers require few to several minutes of acquisition to get a single magnetic field image, rendering the technique temporally static in it's current form. This limitation prevents application of diamond NV magnetometers to novel imaging of dynamically varying microscale magnetic field processes.

Surgical outcomes of laparoscopic dismembered pyeloplasty in children with giant hydronephrosis secondary to ureteropelvic junction obstruction.

Objective: Studies of surgical outcomes after reconstructive surgery for giant hydronephrosis (GH) secondary to ureteropelvic junction (UPJ) obstruction are limited. Over the past two decades, laparoscopic pyeloplasty has gradually replaced open repair in children in several centres. The objective of this study was to assess surgical outcomes of laparoscopic pyeloplasty in children with GH.
