Despite growing research efforts, non-specific low back pain (LBP) remains a major public health burden throughout the industrialized world. Epidemiological data indicate a point prevalence ranging from 19% (Hillman et al., 1996) to 27% (Picavet & Schouten, 2003) and a lifetime prevalence of about 60% (Hillman et al., 1996). Costs to society stem mainly from chronic forms, which account for onl...

To solve the issue of segmenting rich texture images, a novel detection methods based on the affine invariable principle is proposed. Considering the similarity between the texture areas, we first take the affine transform to get numerous shapes, and then utilize the KLT algorithm to verify the similarity. The transforms include rotation, proportional transformation and perspective deformation ...

Assortative mixing in networks is the tendency for nodes with the same attributes, or metadata, to link to each other. It is a property often found in social networks, manifesting as a higher tendency of links occurring between people of the same age, race, or political belief. Quantifying the level of assortativity or disassortativity (the preference of linking to nodes with different attribut...

even though subsequent to the cold war, washington and moscow geostrategic competition came to an end in many parts of the world, a fresh rivalry has been sparked between them in central asia and the caucasus. this rivalry has been developed between regional and transregional powers with the aim of gaining geopolitical advantages, enhancement of security structures, dominance over energy resour...

Drug therapy is a complex and important process and because of the importance of drug interactions, especially in in-patients, accompanying problems and obstacles would exist as a result of concomitant use of drugs in these patients. For this purpose 3130 prescription order forms from Bou-Ali hospital were collected and all potential drug interactions presentwere extracted and evaluated in term...

Why do some places have much higher diversity than others? Explaining patterns of species diversity on the earth is a problem of long-standing for ecologists. Numerous diversity patterns have been documented [1], but the mechanisms behind these patterns remain poorly understood. If we knew the mechanisms, surer decisions in conservation and management would be possible. Understanding can be sou...

Links in many real-world networks activate and deactivate in correspondence to the sporadic interactions between the elements of the system. The activation patterns may be irregular or bursty and play an important role on the dynamics of processes taking place in the network. Information or disease spreading in networks are paradigmatic examples of this situation. Besides burstiness, several co...

From swarming bacteria to social interactions among humans, the emergence of patterns in nature is ubiquitous. Pattern formation is often governed by collective dynamics, wherein individual components of a system begin to move or organize in a coherent way. The generation of patterns in nonlinear dynamical systems is found in nearly all subfields of science and provides insight into some of the...

Reliable facial recognition systems are of crucial importance in various applications from entertainment to security. Thanks to the deep-learning concepts introduced in the field, a significant improvement in the performance of the unimodal facial recognition systems has been observed in the recent years. At the same time a multimodal facial recognition is a promising approach. This paper combi...
