We investigate N = 2 extended superconformal symmetry, using the half-twisted Landau-Ginzburg models. The first example is the D2n+2 -type minimal model. It has been conjectured that this model has a spin n super W current. We checked this by the direct computations of the BRS cohomology class up to n = 4. We observe for n ≤ 3 the super W currents generate the ring isomorphic to the chiral ring...

Extending from the previous semantic privacy-preserving model, we propose a widescale super-peer data integration and protection architecture. Any user from a superpeer domain can contribute new data, schema, or even mappings for other super-peer domains to integrate the information. Each super-peer domain is essentially a mediatorbased data integration system, where an agent at the super-peer ...

As deployed Grids increase from 10s to 1000s of nodes, the construction of an efficient and scalable information system is a key issue, as it is vital for providing querying and discovery services. Today most Grids adopt a centralized or hierarchical model for their information system, but this model is characterized by poor scalability, resiliency and load-balancing features. Nowadays the rese...

Recently, a rapid growth in the population in urban regions demands the provision of services and infrastructure. These needs can be come up wit the use of Internet of Things (IoT) devices, such as sensors, actuators, smartphones and smart systems. This leans to building Smart City towards the next generation Super City planning. However, as thousands of IoT devices are interconnecting and comm...

We present Hand K-band NIRSPEC spectroscopy of super star clusters (SSCs) in the irregular starburst galaxy NGC 1569, obtained at the Keck Observatory. We fit these photospheric spectra to NextGen model atmospheres to obtain effective spectral types of clusters, and find that the information in both Hand K-band spectra is necessary to remove degeneracy in the fits. The light of SSC B is unambig...

trichomoniasis, the most widespread sexually transmitted disease is caused by trichomonas vaginalis. this parasite is site specific for the genitourinary tract and recruitment of macrophages as well as polymorphonuclear nutrophils (pmn) to the site of infection is the first line of defense as a component of non-specific resistance and immunity. in this study, balb/c mice were infected with 10 i...

background and objectives: low fruit/vegetable (fv) diet seems to be a global public health problem. the trans-theoretical stages of change model have long been considered a useful interventional approach in lifestyle modification programs. the aim of this study was to find the most important intermediating factors of fv consumption in mashhad, iran. materials and methods: in this cross-section...

In this paper we propose a new framework for super-resolving facial images under arbitrary pose. While example-based super-resolution methods have demonstrated impressive results for face super-resolution under given pose and imaging conditions, they have limitations dealing with different poses and illuminations. Due to these limitations their application to face super-resolution in generalise...

Interacting populations exhibit complex behavior in nature. Classic quadratic iteration models with two or three populations exhibit some of the features seen in nature, but fail to account for spatial variation. Indeed, the diversity paradox is that many classic population models predict one species dominates while nature exhibits diversity. While various schemes have been presented to address...
