The photonic hook (PH) is new type of curved light beam which has promising applications in various fields such as nanoparticle manipulation, super-resolution imaging, etc. Herein, we proposed a approach utilizing patchy microcylinders for the generation PHs. Numerical simulation based on finite-difference time-domain method was used to investigate field distribution characteristics By rotating...

We study a two-species competition model in patchy advective environment, where the species are subject to both directional drift and undirectional random dispersal between patches there losses of individuals downstream end (e.g., due flow into lake or ocean). The two competing assumed have same growth rates but different advection rates. focus our studies on properties an associated eigenvalue...

Contour integration is believed to occur based on lateral interaction between neurons with similar orientation tuning. The exact neural mechanisms underlying such interactions, and their developmental origins, are not well understood. This paper suggests through computational simulations that synchronization mediated by patchy lateral connections, formed through input-driven self-organization, ...

We discuss the relationship between the local-global map hypothesis of Vl and Spiral Harmonic Mosaic algebra, illustrated with a simple model of Vl. We describe long-range patchy connections by assuming they share a symmetry with the local connectivity. We also show that the elongated pattems of connectivity, implicated in the orientation response property, can be related to the patterns of con...

BACKGROUND Adult onset Still's disease (AOSD) is a rare systemic inflammatory disorder of unknown aetiology, frequently accompanying multiple lymphadenopathy. It often mimics malignant lymphoma, and immunohistochemical and molecular studies are needed for definite diagnosis. AIMS To aid in diagnosis and understand the pathogenesis of the disease by clarifying lymph node (LN) pathology in AOSD...
