Using linearized superfields, R 4 terms in the Type II superstring effective action com-pactified on T 2 are constructed as integrals in N=2 D=8 superspace. The structure of these superspace integrals allows a simple proof of the R 4 non-renormalization theorems

The class of deterministic ’Daphnia’ models treated by Diekmann et al. (J Math Biol 61: 277–318, 2010) has a long history going back to Nisbet and Gurney (Theor Pop Biol 23: 114–135, 1983) and Diekmann et al. (Nieuw Archief voor Wiskunde 4: 82–109, 1984). In this note, we formulate the individual based models (IBM) supposedly underlying those deterministic models. The models treat the interacti...

Abstract Aim Groin mesh explantation is a challenging situation and multidisciplinary approach at index surgery can avoid long term catastrophic for the patient . Material & Method The history of started decade back with bilateral laparoscopic TAPP, following which he had swelling in both groin area high grade fever He was advised open exploration explant mesh. Post procedure kept on antibi...

Abstract Aim To describe the incidence of mesh infection after inguinal hernia repair and treatment given as well to investigate possible risk factors. Material & Methods Patients with a groin in one Sweden's health care regions during 2005–2020 were identified Swedish Hernia Register (SHR). Data from SHR was collected for all patients reported infectious complication matched (1:1) referenc...
