with an occurrence of 7%, appendicitis is one of the most common abdominal emergencies requiring surgery. since the variation in positions and length of the appendix may produce varying symptoms and signs which mimic other diseases, having knowledge of the variations in the position of the appendix is of significant importance. here, we present a 77-year-old man with acute appendicitis presenti...

background: delayed reporting resulting in advanced stage disease is a common problem in indian cancer patients. this study analysed the impact of various sociodemographic and psychosocial factors on the delayed reporting to healthcare professional (hcp) in oral and oropharyngeal cancer patients. methods: this cross sectional observational study was conducted using a structured questionnaire. q...

We consider a model for an infectious disease in the onset of an outbreak. We introduce contact tracing incorporating a tracing delay. The effect of randomness in the delay and the effect of the length of this delay in comparison to the infectious period of the disease respectively to a latency period on the effect of tracing, given e.g. by the change of the reproduction number, is analyzed. We...

The role of interleukin-2 (IL-2) in tumor dynamics is illustrated through mathematical modeling, using delay differential equations with a discrete time delay (a modified version of the Kirshner-Panetta model). Theoretical analysis gives an expression for the discrete time delay and the length of the time delay to preserve stability. Numerical analysis shows that interleukin-2 alone can cause t...

Once upon a time, the delay of a circuit was well approximated as the sum of the delays of the gates. Wires could be viewed as equipotential nodes that instantly carried the voltage to all ends. As transistors have shrunk, the relative delay of gates has decreased. At the same time, the delay of wires per unit length has actually increased. Thus, wires now are a very important part of total delay.

hypothalamic hamartoma (hh) is a rare intracranial lesion that usually presents with classic triad of central precocious puberty, gelastic epilepsy, and developmental delay. herein, a 14-year old boy is presented in whom the diagnosis of hh was made by magnetic resonance imaging. while he did not have any complain of precocious puberty, he surprisingly suffered from delay in puberty. the defini...

Abstract : A popular technique for time delay estimation is to use an FIR filter to model the time difference and the filter weights are interpolated with a sinc function to obtain the delay estimate. However, the sinc interpolator requires a sufficiently long filter length for accurate delay estimation. In this paper, we propose to process the filter weights via a least squares based method in...

background: tuberculosis (tb) is still a major cause of morbidity and mortality in both developed and developing countries. delay in accessing tuberculosis care is associated with the highest densities of mycobacterium tuberculosis (m. tuberculosis) bacilli on sputum smears. objectives: the current study aimed to determine the extent of delay, and the major health system contributing factors to...
