in this paper, a new method is introduced for sperm detection in microscopic images for infertility treatment. in this method, firstly a hypothesis testing function is defined to separate sperms from plasma, non-sperm semen particles and noise. then, some primary candidates are selected for sperms by watershed-based segmentation algorithm. finally, candidates are either confirmed or rejected us...

today’s, a common problem in cities is increasing delay and reducing the speed of traffic. on the other wise increasing costs of acquisition in urban area are not allow new routes and highways. also construction of new highway or street such as imam ali highway and sadr highway in tehran lead to develop new applications (such as brt lane ,…) and become quickly saturate and less efficient. there...

introduction automated methods for sperm characterization in microscopic videos have some limitations such as: low contrast of the video frames and possibility of neighboring sperms to touch each other. in this paper a new method is introduced for detection of sperms in microscopic videos. materials and methods in this work, first microscopic videos are captured from specimens of human semen. s...

background: nepeta menthoides boiss & buhse is a species from lamiaceae family. it is used as a herbal medicine with common name “ostokhodus” in iranian traditional and folk medicine but there is not enough information about its quality and quantity control methods. objective: in this study we use micromorphological and phytochemical evaluations for qualitative and quantitative control of n. me...

Plasmodium falciparum infections are frequently fatal if untreated and hence need to be diagnosed and treated early. Malaria diagnosis, with conventional Giemsa staining as a gold standard, has had several limitations. New rapid and accurate methods are needed for diagnosis. In this study, polymerase chain reaction (PCR) analysis specific for diagnosis of P. falciparum was evaluated. For the st...

For a system of noninteracting electrons scattered by neutral impurities, we derive a modified Boltzmann equation that includes quasiparticle and virial corrections. We start from a quasiclassical transport equation for nonequilibrium Green’s functions and apply a limit of small scattering rates. The resulting transport equation for quasiparticles has gradient corrections to scattering integral...

These lecture notes are dedicated to Dierk Rainer on the occassion of his 60th birthday in 2001. He pioneered the systematic treatment of the low-energy scale in the electronic theory of condensed matter.

We read the interesting paper by Pardi et al on the epidemiology of microscopic colitis in Olmsted County, Minnesota, USA (Gut 2007; 56: 504–8). They concluded that the incidence of microscopic colitis increased significantly over time, and by the end of the study, the incidence and prevalence were significantly higher than reported previously. In fact, compared with other epidemiological studi...
