Background: LASIK for refractive error correction has become a universal surgery.Despite its popularity, the estimated prevalence of traumatic flap dislocations in post-LASIK patients is 3.9%, and it is sometimes associated with epithelial ingrowth.The prognosis in such cases depends on the rapid surgical revision of the flap with the removal of th
Extracorporeal membrane oxygenation CD Wire Harness (ECMO) is increasingly being employed in South African intensive care units for the management of patients with refractory hypoxaemia and for haemodynamic support, particularly following cardiothoracic procedures.ECMO is expensive, however, and there is a danger that this rescue modality may be ab
When users upload their private data to the cloud, they lose control of the data stored in the cloud server.If the cloud system cannot provide an effective security mechanism to protect the data, the consequent data leakage issue will hinder the development of cloud computing.Conventional access control and encryption technologies cannot effectivel
GNSS positioning accuracy can be degraded in areas where the surrounding object geometry and morphology interacts with the GNSS signals.Specifically, urban environments pose challenges to precise GNSS positioning because of signal interference or interruptions.Also, non-GNSS surveying methods, including total stations Controls and laser scanners, i
