Introduction Obesity has affected an approximated 300 million people in the worldwide (1). Its prevalence is expanding in both developed and developing countries. Type 2 diabetes may be the most destructive result that related to obesity (1). The risk of type 2 diabetes increases as body mass index (BMI) increases (2). The prevalence of type 2 diabetes is 3-7 times more in obese adults (3). The...

Antenna design problems often require the optimization of several conflicting objectives such as gain maximization, sidelobe level (SLL) reduction and input impedance matching. Multiobjective Evolutionary Algorithms (MOEAs) are suitable optimization techniques for solving such problems. An efficient algorithm is Generalized Differential Evolution (GDE3), which is a multi-objective extension of ...

Cellulomonas denverensis is a small and thin gram-positive rod-shaped bacterium that was proposed as a new species in 2005. Here we report a female case of acute cholecystitis and sepsis in which C. denverensis was determined to be causative.

OBJECTIVES To examine the relationship between the combination of alcohol and benzodiazepines and the risk of committing an unsafe driver action. METHODS We used data from the Fatality Analysis Reporting System (1993-2006) on drivers aged 20 or older who were tested for both alcohol and drugs. Using a case-control design, we compared drivers who had at least one unsafe driver action (UDA; e.g...

We present optimization results obtained for two type of antennas using evolutionary algorithms. A quadrifilar helical UHF antenna is currently flying aboard NASA’s Mars Odyssey spacecraft and is due to reach final Martian orbit insertion in January, 2002. Using this antenna as a benchmark, we ran experiments employing a coevolutionary genetic algorithm to evolve a quadrifilar helical design in...

This paper presents a design of Wide-Band Microstrip Yagi-Uda antenna with high gain and high front to back (F/B) ratio. Numerical and measured results of our design show more than 18 dB front to back ratio at 5.5 GHz and no backward radiation at 5.2GHz. An impedance bandwidth of 22.05% was achieved around 5.5GHz. The antenna gain (10–12.4 dBi) can be varied to be suitable for various applicati...

In this paper, a printed wideband Yagi-Uda antenna with a novel folded dipole driver is proposed. The folded dipole driver is comprised of a folded dipole and a microstrip feedline which functions as an internal balun to mainly determine its wide impedance bandwidth. With the optimized parameters, an operating band of 1.69 GHz ∼ 2.72 GHz can be obtained. Besides the folded dipole driver, the br...

Trypanosoma brucei variant surface glycoproteins (VSG) are glycosylated by both paucimannose and oligomannose structures which are involved in the formation of a protective barrier against the immune system. Here, we report that the stinging nettle lectin (UDA), with predominant N-acetylglucosamine-binding specificity, interacts with glycosylated VSGs and kills parasites by provoking defects in...
