In this paper, the marginal distribution of concomitants k − record values (CKR) based on Huang–Kotz Farlie–Gumbel–Morgenstern (HK-FGM) family bivariate distributions is derived. addition, we obtained joint CKR for family. Also, hazard rate, reversed and residual life functions using HK-FGM The weighted extropy ...

in this article, three techniques for maxillo-mandibular relationship for replace-select implants are described. the use of healing abutments, planning abutments, and impression copings are presented, and the advantages and disadvantages are discussed.

An isolated, articulated, but crushed ossified lung of a mawsoniid coelacanth is reported from uppermost Cretaceous (upper Maastrichtian) Oued Zem, Morocco. The specimen the last record before their pseudo-extinction at end Mesozoic. also first marine in Mesozoic Morocco and occurrence coelacanths phospahte deposits North Africa. large size suggests fish estimated between 3.65 m 5.52 total body...

We consider dynamic link networks(DLN), where nodes are static, but the links are highly dynamic. Reliable multi-hop communication is critical in such networks, which inspires receiver contention routing, which elects relays from actual receivers to overcome link dynamics. However, in previous studies of receiver contention routing protocols, the multi-hop reliability is lack of deep understand...

The fossil record of early vertebrates has been influential in elucidating the evolutionary assembly of the gnathostome bodyplan. Understanding of the timing and tempo of vertebrate innovations remains, however, mired in a literal reading of the fossil record. Early jawless vertebrates (ostracoderms) exhibit restriction to shallow-water environments. The distribution of their stratigraphic occu...
