Bacillus thuringiensis subsp. israelensis (Bti) is increasingly used worldwide for mosquito control and is the only larvicide used in the French Rhône-Alpes region since decades. The artificial selection of mosquitoes with field-persistent Bti collected in breeding sites from this region led to a moderate level of resistance to Bti, but to relatively high levels of resistance to individual Bti ...

Although recent experimental studies indicate that disc-derived cytokines, as for instance TNF, seems to be intimately involved in the pathophysiology of sciatica and low back pain, the clinical studies performed do not provide conclusive data on TNF-inhibition as a useful complement for treatment of such conditions to existing modalities. Based on the fact that TNF is merely one component in a...

A Bäcklund transformation(BT) and a recurrence formula are derived by the homogeneous balance(HB) method. A initial problem of Burgers equations is reduced to a initial problem of heat equation by the BT, the initial problem of heat equation is resolved by the Fourier transformation method, substituting various solutions of the initial problem of the heat equation will yield solutions of the in...

Video segmentation can be considered as a clustering process that classifies one video succession into several objects. Spatial information enhances the quality of clustering which is not utilized in the conventional FCM. Normally fuzzy c-mean (FCM) algorithm is not used for color video segmentation and it is not robust against noise. In this paper, we presented a modified version of fuzzy c-me...

Efficient frequency-domain full-waveform inversion (FWI) of long-offset node data can be performed with a few frequencies. The seismic response these frequencies computed compact finite-difference stencils on regular Cartesian grid direct or hybrid direct/iterative methods. Compactness, which is necessary to mitigate the fill-in induced by lower-upper factorization, implemented second-order ste...

Fifty percent of the titles I've addressed since embarking on writing this article series are a result of my having received 5 or more concerned phone calls relating to a given subject. This installment: The latest or updated generation of Computerized Maintenance Management Systems selling techniques to be encountered at the National Manufacturing Week Conference in Chicago: 1) Are you going t...
