Previous work on sample design has been focused on constructing designs for samples taken at point locations. Significantly less work has been done on sample design for data collected along transects. A review of approaches to point and transect sampling design shows that transects can be considered as a sequential set of point samples. Any two sampling designs can be compared through using eac...

Geophysical inversion using least-squares has been a very successful method for UXO discrimination of magnetics. However, the residuals do not follow a normal distribution, which means that the assumptions underlying the inverse problem are violated. Two consequences of this are (i) model bias and (ii) incorrect estimates of model parameter uncertainties. We have found that the residuals are be...

h.pylori infection stimulates immune responses. these responses at the mucosal level are predominantly of iga types, while circulating antibodies against this microorganism are predominantly igg classes. igm antibodies are rarely found and seem to be non-specific for this bacterium. in this research, water extract antigen, from three strains of h.pylori (isolated from patients with gastritis, d...

a label-free electrochemical nucleic acid aptasensor for the detection of methamphetamine (ma) by the immobilization of thiolated self-assembled dna sequences on a gold nanoparticles-chitosan modified electrode is constructed. when ma was complexed specifically to the aptamer, the configuration of the nucleic acid aptamer switched to a locked structure and the interface of the biosensor changed...

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

leishmaniasis is a common parasitic disease in tropical and subtropical areas of the world. police personnel deployed in the suburbs and rural areas are the most often exposed to the potential risk of cutaneous leishmaniasis. furthermore, since the same police personnel are sent on duty to other places, their migrations can also play a considerable role in the transmission of this disease to th...
