Introduction Namibia is a high tuberculosis (TB)-burden country with an estimated incidence of 460/100 000 (around 12 000 cases) per year. Approximately 4.5% of new cases and 7.9% of previously treated TB cases are multidrug resistant (MDR) and 47% o

Photodiodes for Terahertz Applications
Autor: Cyril C. Renaud, Chris Graham, Xiaoli Lin, James Seddon, Michele Natrella, Alwyn J. Seeds
Publikováno v: IEEE Journal of Selected Topics in Quantum Electronics. 28:1-12
Terahertz generation using high-speed photodiodes has found commercial application in many areas ranging across spectroscopy, imaging and communications. In this paper we discuss the optimization of high-speed photodiodes in terms of bandwidth and ou

Treatment decision algorithms for childhood tuberculosis
Autor: James Seddon
Publikováno v: Open Access Government. 36:120-121
Treatment decision algorithms for childhood tuberculosis For most adults, the diagnosis of TB is made by the individual coughing sputum into a pot and with the sample then evaluated in a laboratory to look for the TB bacteria (or genetic components o

Modeling and Measurement of a HSQ Passivated UTC-PD with a 68.9 GHz Bandwidth
Autor: Cyril C. Renaud, Lianping Hou, Shengwei Ye, John H. Marsh, Xiao Sun, James Seddon
Publikováno v: 2021 IEEE Photonics Conference (IPC).
An InGaAs uni-traveling-carrier photodiode passivated using hydrogen silsesquioxane (HSQ) is reported. The device was fabricated and also simulated using 3D full-wave and equivalent circuit modeling. Both experimental and modeled results show a −3

Autor: Sanjay Jain, Regan Solomons, Ravindra Kumar Garg, Manish Modi, Guy Thwaites, David Boulware, Ursula Karin Rohlwink, SATISH CHANDRA, Anthony A. Figaji, David Meya, Raph Hamers, Robert Wilkinson, James Seddon
Publikováno v: Wellcome Open Research
Tuberculous meningitis (TBM) is the most severe and disabling form of tuberculosis (TB), accounting for around 1-5% of the global TB caseload, with mortality of approximately 20% in children and up to 60% in persons co-infected with human immunodefic
