The leaf blade anatomy of Ehrharta villosa Schult.f.var.villosa, var.maxima Stapf and E.thunbergii Gibbs Russell is described and illustrated.These three taxa, constituting the Villosa species group, share a diagnostic leaf anatomy distinguished by the absence of a distinct midrib, adaxial semi-radiate mesophyll with the abaxial chloren- chyma pali
In this paper, we derive accurate outage probability and bit error rate expressions for EFA a high altitude platform station (HAPS) assisted terrestrial communication system.In particular, HAPS is deployed as a relay node to assist two ground stations for data transmission.Each ground station-to-HAPS communication link works on a hybrid radio frequ
Chronic Bee Paralysis Virus (CBPV), a widespread honey bee RNA virus, causes massive worker bee losses, mostly in strong colonies.Two different syndromes, with paralysis, ataxia and flight incapacity on one hand and black hairless individuals with shortened Denim Tops abdomens on the other, can affect a colony simultaneously.This case report presen
Terminally differentiated (TD) cells permanently exit the mitotic cycle while acquiring specialized characteristics.Although TD cells can be forced to reenter the cell cycle EFA by different means, they cannot be made to stably proliferate, as attempts to induce their replication constantly result in cell death or indefinite growth arrest.There is
MOOCs (massive open online courses) are popular distance courses for which anyone can sign up online with no limits on the number of participants.Moreover, artificial intelligence is a combination of algorithms for the development of human and rational capabilities by machines.This article presents a quantitative study with a sample of 734 MOOCs on
