Curative treatment for base-of-tongue squamous cell carcinoma (BOT SCC) has evolved over time; however, comparative outcomes analysis for various treatment strategies is lacking. The authors reviewed the evolution of treatment modality and radiotherapy (RT) technique for 231 consecutive BOT SCC patients at our institution between 1981 and 2011. Treatment modalities included definitive chemoradi...

In this study, path analysis modeling is applied to examine the relationships among e-learning systems, self-efficacy, and students’ perceived learning outcomes in the context of university online courses. Independent variables included in the study are e-learning system quality, information quality, computer self-efficacy, system-use, self-regulated learning behavior, and user satisfaction as ...

Patients seek attention and treatments to various types of diseases and symptoms. Diseases infection and symptoms are often not predictive. Normally, there is a spread and movement of people across the geographical locations, of both the rural and urban communities, in countries including Namibia. As such, healthcare could be needed at any location, and at any time. There is significant mobilit...

The study analyzed farm households’ access and utilization of government health facilities in Kogi State, Nigeria. Specifically, it described the socioeconomic characteristics of farm households, determined the level of accessibility to health facilities by farm households, and determined the factors that drive farm households’ utilization of government health facilities. A two staged random sa...

Previous research has shown an inverse relation between response times in elementary cognitive tasks and intelligence, but findings are inconsistent as to which is the most informative score. We conducted a study (N = 200) using a battery of elementary cognitive tasks, working memory capacity (WMC) paradigms, and a test of fluid intelligence (gf ). Frequently used candidate scores and model par...

In this paper a discrete-time design of continuous-time delay (TDC) is presented. The main goals are: (i) to eliminate the TDC assumption of accessibility to all the delayed derivative of the plant state variables, and (ii) to design discrete-time controllers based on approximate discrete-time models. Simulations results are given, for an articulated arm actuated with linear hydraulic motors wi...

In medical imaging, computer vision researchers are faced with a variety of features for verifying the authenticity classifiers an accurate diagnosis. response to coronavirus 2019 (COVID-19) pandemic, new testing procedures, treatments, and vaccines being developed rapidly. One potential diagnostic tool is reverse-transcription polymerase chain reaction (RT-PCR). RT-PCR, typically time-consumin...
