Intact cells of the yeast Saccharomyces cerevisiae were transformed with exogenous DNA by incubating the cells with plasmid in the presence of polyethylene glycol (PEG), which has been shown to be required, although the underlying has not been elucidated. In this study, we found that incubation of the S. cerevisiae cells with PEG was not only required for(More)
We describe a case of a 73-year-old man who presented with right-sided abdominal pain associated with palpable mass. Initial laboratory examination was normal except lactate dehydrogenase level. Subsequent CT image showed situs inversus and splenic mass with multiple lymph nodes enlargement. Biopsy taken from the splenic mass demonstrated mantle cell(More)
This paper investigates an algorithm, which improves the task completion rate for simple swarm robots implementing a leaf-curling task. In this biologically inspired task, robots collaborate to find a suitable place to bend a leaf, which allows them to successfully fold it up. To complete the task simple robots were developed that are not equipped with any(More)
This paper presents an algorithm, which improves the probability of success for simple swarm robots implementing an extended version of the leaf curling task – one part of the nest building activity of weaver ants [Phan and Russell, 2009, 2010]. The robots are required to have only very basic sensing abilities, and are allowed to transfer information using(More)
A new transimpedance amplifier (TIA), which divides the feedback resistor into shunt- and series-connection to the current source of the buffer, is proposed. The proposed TIA provides high linearity without sacrifice in gain and noise performances as the series-connected feedback resistor does not contribute to linearity degradation. The advantage of the(More)
