At redshifts beyond z ∼> 6, as the mean fraction of neutral hydrogen 〈xHI〉 in the intergalactic medium (IGM) increases, the line flux of Lyα emitters can be significantly suppressed, which can result in a decrease in the observed number of emitters at a given Lyα flux. However, cosmological HII regions surrounding the Lyα emitting galaxies alleviate these effects. We use simple models of the Ly...

To understand the connection between the dynamics of microscopic turbulence and the macroscale power scaling in the L–I–H transition in magnetically confined plasmas, a new time-dependent, one-dimensional (in radius) model has been developed. The model investigates the radial force balance equation at the edge region of the plasma and applies the quenching effect of turbulence via the E × B flo...

Zero-shot learning (ZSL) aims to recognize objects from novel unseen classes without any training data. Recently, structuretransfer based methods are proposed to implement ZSL by transferring structural knowledge from the semantic embedding space to image feature space to classify testing images. However, we observe that such a knowledge transfer framework may suffer from the problem of the geo...

We introduce the notions of strongly zero-product (strongly Jordan zero-product) preserving maps on normed algebras. These notions are generalization of the concepts of zero-product and Jordan zero-product preserving maps. Also for a non-zero vector space V and for a non-zero linear functional f on V, we equip V with a multiplication, converting V into an associative algebra, denoted by Vf . We...
