- Glass-clad, GaSb-core fibers were drawn and subsequently laser annealed. The as-drawn fibers were found to be polycrystalline, possess Sb inclusions, and have oxide contamination concentrations of less than 3 at%. Melting and resolidifying regions in the cores using 10.6 mu m CO2 laser radiation yielded single crystalline zones with enhanced photoluminescence (PL), including the first observation of strong room temperature PL from a crystalline core fiber. Annealed fibers show low values of tensile strain and a bandgap close to that of bulk GaSb.

- To investigate which type of hernia that has the highest risk of a recurrence after a primary Lichtenstein repair. Male patients operated on with a Lichtenstein repair for a primary direct or indirect inguinal hernia and with a TEP for a later recurrence, with both operations recorded in the Swedish Hernia Register (SHR), were included in the study. The study period was 1994-2014. Under the study period, 130,037 male patients with a primary indirect or direct inguinal hernia were operated on with a Lichtenstein repair. A second operation in the SHR was registered in 2236 of these patients (reoperation rate 1.7 %). TEP was the chosen operation in 737 in this latter cohort. The most likely location for a recurrence was the same as the primary location. If the recurrences change location from the primary place, we recognized that direct hernias had a RR of 1.51 to having a recurrent indirect hernia compared to having a direct recurrence after an indirect primary hernia repair. Recurrent hernias after Lichtenstein are more common on the same location as the primary one, compared to changing the location.
