Neuronal adaptation as well as interdischarge interval correlations have been shown to be functionally important properties of physiological neu-rons. We explore the dynamics of a modified leaky integrate-and-fire (LIF) neuron, referred to as the LIF with threshold fatigue, and show that it reproduces these properties. In this model, the postdischarge threshold reset depends on the preceding se...

Meal-induced thermogenesis (MIT) research findings have been highly inconsistent, in part, due to the variety of durations and protocols used to measure MIT. In the present study, we aimed to determine the following: (1) the proportion of a 6 h MIT response completed at 3, 4 and 5 h; (2) the associations between the shorter durations and the 6 h measures; (3) whether shorter durations improved ...

MIT students have become addicted to two new popular websites, MIT FML (http://mitfml.com/) and I Saw You MIT (http://isawyou. mit.edu/), created this past semester. Filled with anonymous, quirky, Twitter-like posts the two sites were designed to entertain, bond, and poke fun at the MIT community. “We are living in such a stressful and yet entertaining atmosphere, it would be a great idea to ha...

The coffee berry borer, Hypothenemus hampei (Ferrari), continues to pose a formidable challenge to coffee growers worldwide. Because of the cryptic life habit of the insect inside coffee berries, effective pest management strategies have been difficult to develop. A sesquiterpene, (E,E)-α-farnesene, produced by infested coffee berries has been identified as a potential repellent against the cof...

Suppression of noise and artifacts is a necessary step in biomedical data processing. Adaptive filtering is known as useful method to overcome this problem. Among various contaminants, there are some situations such as electrical activities of muscles contribute to impulsive noise. This paper deals with modeling real-life muscle noise with α-stable probability distribution and adaptive filterin...

Many biological assays have as their basis a link to the oxidative status of nicotinamide adenine dinucleotide (NAD) or nicotinamide adenine dinucleotide phosphate (NADP). Many dehydrogenase enzymes use these coenzymes to transfer hydrogen groups between molecules. Because the reduced forms of these molecules differ from the oxidized forms in their ability to absorb light, it is possible to qua...

Introduction: Teaching styles and methods have been constantly changing in the recent years. In the 1980s and 90s, the world was introduced to various developed devices, such as smart boards and early generation smart phones that had an immediate innovative effect on education. These advancements has resulted in a considerable improvement in the current educational techniques. The innovations i...

Sinnvolle Navigation im Felsenbein kann erst dann erfolgen, wenn die erzielte Anwendungsgenauigkeit im submillimetrischen Bereich oder maximal knapp darüberist. Die Anwendungsgenauigkeit des open4Dnav Navigationssystems wurde in einem Laborexperiment an einem Plastikschädel mit implantierten Schrauben, einer im hinteren Nasengang liegenden Registrierungsvorrichtung und mit dem Aurora Tracker vo...
