Revisiting Vaidya Horizons
In this study, we located and compared different types of horizons in the spherically symmetric Vaidya solution. The horizons we found were trapping horizons, which can be null, timelike, or spacelike, null surfaces with constant area change and also conformal Killing horizons. The conformal Killing horizons only exist for certain choices of the mass function. Under a conformal transformation, ...

Antidepressant treatments may exert their therapeutic effects by stimulating appropriate adaptive changes in neuronal systems. Re...

In the mid-19th century, the humoral theory of breast cancer was overturned by a mechanistic model viz., ‘it arises in the breast and spreads centrifugally to regional lymph nodes and thence to rest of the body’. Charles Moore, (1821–1879) a surgeon from the Middlesex Hospital in London, among others, believed that the only way to cure breast cancer was very...
