On the base of Lie algebraic and differential geometry methods, a wide class of multidimensional nonlinear integrable systems is obtained, and the integration scheme for such equations is proposed. 1. In the report we give a Lie algebraic and differential geometry derivation of a wide class of nonlinear integrable systems of partial differential equations for the functions depending on an arbit...

While direct social ties have been intensely studied in the context of computer-mediated social networks, indirect ties (e.g., friends of friends) have seen little attention. Yet in real life, we often rely on friends of our friends for recommendations (of good doctors, good schools, or good babysitters), for introduction to a new job opportunity, and for many other occasional needs. In this wo...

We address the problem of describing, recognizing, and learning generic, free-form objects in real-world scenes. We introduce a hybrid appearance-based approach, IDEAL, where objects are encoded as a loose collections of parts and the relations between them. The key features of this new approach are the structural part decomposition combining multi-scale wavelet segmentation and hierarchical bl...

Geocast mechanisms allow a sender to transmit network packets to receivers residing at a certain geographical region. Geocast forms the basis for a number of location-based services, such as announcement services, advertisement services or friend-finders. In this paper, we introduce the notion of semantic geocast, where a target area is specified by its meaning. A sender can broadcast messages ...

UNLABELLED Avian and possum fecal droppings may negatively impact roof-harvested rainwater (RHRW) water quality due to the presence of zoonotic pathogens. This study was aimed at evaluating the performance characteristics of a possum feces-associated (PSM) marker by screening 210 fecal and wastewater samples from possums (n = 20) and a range of nonpossum hosts (n = 190) in Southeast Queensland,...

An improved study to the s wave πK elastic scatterings and the kappa resonance Abstract We point out that the dispersion relation for the left hand cut integral presented in one of our previous paper (Nucl. Phys. A733(2004)235) is actually free of subtraction constant, even for unequal mass elastic scatterings. A new fit to the LASS data is performed and we find a κ pole with M κ = 694 ± 53M eV...

Trend of rapid urbanization has increased the number of hilly communities around many large cities and raise both water and energy consumption, as modern water supply systems heavily depend on energy supply. Locally available rainwater was examined in this study as a potential approach for urban water-energy conservation scheme. Using hilly communities of Taipei Metropolitan as a case study, th...

Despite recent efforts to investigate the distribution and fate of polycyclic aromatic hydrocarbons (PAHs) in air, water, and soil, very little is known about their temporal change in wet deposition. As a result of increased attention to public health, a large-scale survey on the deposition flux and distribution of PAH contamination in rainwater was urgently conducted in Shanghai, China. In thi...
