Storefront brand image (logo) recognition has many useful applications such as location recognition and advertisement. Various methods have been proposed using local and global feature matching. However, it continues to be a challenging area; unlike nature scene images, which are rich in texture details, brand images often lack texture variation, and therefore provide fewer feature points for m...

A system for realtime terrain triangulation is presented which allows fully user controllable and smooth level of detail transitions. To accomplish this as well as to ooer the possibility of data compression, the terrain elevation data is hierarchically interpolated. The interpolation error, the so called hierarchical surplus, is used as a criterion to detect redundant data and serves as a way ...

We investigate the minimum cases for realtime probabilistic machines that can define uncountably many languages with bounded error. We show that logarithmic space is enough for realtime PTMs on unary languages. On binary case, we follow the same result for double logarithmic space, which is tight. When replacing the worktape with some limited memories, we can follow uncountable results on unary...

OBJECTIVE Estrogen interacts with a membrane receptor, G protein-coupled estrogen receptor (GPER). It was reported that 17β-estradiol was able to inhibit contraction of the human colon and cause relaxation of the guinea pig gallbladder, however, the involvement of GPER was not clarified. The aim of the present study was to investigate the effect of estrogen on human gallbladder motility and the...

Open sandwich (OS) immunoassay utilizes antigen-dependent stabilization of an antibody variable region to quantify various antigens, enabling noncompetitive detection of small molecules with a broad working range. For further improvement of its sensitivity, OS Immuno-PCR was attempted with recombinant fusion proteins. The maltose binding protein-fused heavy chain variable region (MBP-V(H)) of a...

BACKGROUND There is an urgent need to develop rapid and accurate point-of-care (POC) technologies for acute scrub typhus diagnosis in low-resource, primary health care settings to guide clinical therapy. METHODOLOGY/PRINCIPAL FINDINGS In this study we present the clinical evaluation of loop-mediated isothermal PCR assay (LAMP) in the context of a prospective fever study, including 161 patient...

INTRODUCTION Enterovirus (EV) and parechovirus (PeV) can either infect humans asymptomatically or can cause gastroenteritis, respiratory symptoms and, sometimes, severe disease. As the number of newly identified EV and PeV genotypes keeps increasing, diagnostic methods need to be updated. To this end, we described a novel multiplex one-step real-time RT-PCR to detect EV and human PeV (HPeV) sim...

The development of instruments that allowed real-time monitoring of fl uorescence within PCR reaction vessels was a very signifi cant advance. The technology is very flexible and many alternative instruments and fl uorescent probe systems have been developed and are currently available. Real-time PCR assays can be completed very rapidly since no manipulations are required post-amplifi cation. I...

introduction ventilator-associated pneumonia (vap)  is one of the most serious and  prevalence of  complication  among patients in the intensive care unit nosocomial infections, which are often recognized after detecting symptoms. to date, there has been no proper clinical and diagnostic marker for early detection of this disease. in this study, two hcn4 and adam8 genes in patients with vap wer...
