Oriented Open-Closed String Theory Revisited [PDF]

open access: yes, 1997
String theory on D-brane backgrounds is open-closed string theory. Given the relevance of this fact, we give details and elaborate upon our earlier construction of oriented open-closed string field theory.

Nurses' Use of Ultrasound Location for Puncturing Arteriovenous Fistulas in Hemodialysis

open access: yesSaudi Journal of Kidney Diseases and Transplantation, 2022
Puncturing an arteriovenous fistula (AVF) in chronic hemodialysis (HD) patients is a source of difficulty even for experienced dialysis nurses. The objective of this study was to compare the failure rate of AVF puncture by the usual technique (visual or ...

Farrell cohomology of low genus pure mapping class groups with punctures

open access: yes, 2002
In this paper, we calculate the p-torsion of the Farrell cohomology for low genus pure mapping class groups with punctures, where p is an odd prime. Here, `low genus' means g=1,2,3; and `pure mapping class groups with punctures' means the mapping class ...

Quiver Tails and N=1 SCFTs from M5-branes [PDF]

open access: yes, 2015
We study a class of four-dimensional N=1 superconformal field theories obtained by wrapping M5-branes on a Riemann surface with punctures. We identify UV descriptions of four-dimensional SCFTs corresponding to curves with a class of punctures. The quiver
