We briefly review some common diffusion-limited reactions with emphasis on results for two-species reactions with anisotropic hopping. Our review also covers single-species reactions. The scope is that of providing reference and general discussion rather than details of methods and results. Recent exact results for a two-species model with anisotropic hopping and with ‘sticky’ interaction of li...

Abstract We present a performance test of the point-spread function (PSF) deconvolution algorithm applied to astronomical integral field unit (IFU) spectroscopy data for restoration galaxy kinematics. deconvolve IFU by applying Lucy–Richardson 2D image slice at each wavelength. demonstrate that can effectively recover true stellar kinematics galaxy, using mock with diverse combination surface b...

A research study was conducted for estimating the water spread area of tanks in Cheyyar sub basin year 2022. Tanks are low-cost irrigation source and play a key role recharge ground water. Mapping regular monitoring plays an important resource planning. Sentinel-1A SAR data has high potential as it is unaffected by cloud cover, light or weather conditions. After processing obtained satellite us...

75 Abstract—Data demonstrate the effect of slope on heading and backing fires burning through woody fuels. The data indicate that the upper limit of heading fire rate of spread is defined by the rate of spread up a vertical fuel array, and the lower limit is defined by the rate of spread of a backing fire burning downslope. The minimum spread rate is found to occur at nominally –16 degrees slope.

A kinetic model has been proposed for the spread of epidemics, describing dynamics variation in number disease-free, infected, and recovered (SIR) cases, based on a lag logistic equation. It established that this predicts possibility existence quasi-steady-state mode an epidemic which infected cases is constant due to balance daily increment infections recoveries. Conditions have identified und...
