We report the first definitive Nusselt number scale of thermal boundary layers from curved surfaces characterized by proposed non-dimensional curvature parameter ξ = R0/(HRa−1/4), where R0 denotes radius a surface, H corresponding finite height, and Ra global Rayleigh virtual reference layer on vertical flat surface. The is given Nu ∼ ξ−1/5Ra1/4 in which Ra1/4 for surface case, revealing that c...

We revisit the possibility of detecting an extrasolar planet around a background star as it crosses the fold caustic of a foreground binary lens. During such an event, the planet’s flux can be magnified by a factor of ∼ 100 or more. We find that the detectability of the planet depends strongly on the orientation of its orbit relative to the caustic. If the source star is inside the inter–causti...

We study light variability of gravitationally magnified high-redshift star clusters induced by a foreground population microlenses. This arises as the incoherent superposition variations from large number source stars traversing random magnification pattern on plane. The curve resembles scale-invariant, Gaussian process timescales years to decades, while exhibits rapid and frequent micro-causti...

The notion that apparent sizes are perceived relative to the size of one's body is supported through the discovery of a new visual illusion. When graspable objects are magnified by magnifying goggles, they appear to shrink back to near-normal size when one's hand (also magnified) is placed next to them. When objects are "minified" by minifying goggles, the opposite occurs. The rescaling effect ...

Scarcity of water for irrigation is an alarming issue of Pakistan and the problem is being magnified rapidly with the passage of time. Shortage of water is thus, a limiting factor in increasing per unit area wheat (Triticum aestivum L.) yield that is staple food of most of the people. Eventually, the gap between production and consumption is widening day by day and Pakistan is now suffering fro...
