Abstract We assess the differential impact of geopolitical risk on Islamic and conventional gold backed cryptocurrencies using a multivariate Generalized Autoregressive Conditional Heteroscedasticity (M-GARCH) modeling. unveil that gold-backed behave differently from their counterparts. Sharia compliant are positively correlated to yellow metal, while ones weakly negatively associated gold. fin...

Tit-for-Tat strategy is a in repeated two-player symmetric games which imitates the previous action of opponent. We show that zero-determinant strategy, unilaterally equalizes expected payoffs two players, if and only stage game potential game. Because it has been known this condition equivalent to unbeatable, our results suggest some relation between unbeatable property concept strategy.

Abstract— In this paper, the trapezoidal ring antenna using the conductor-backed CPW is designed and fabricated. The antenna has a broadband characteristic by the coupling effects through inserted the H-shaped parasitic patch. The conductor-backed CPW shows more stable characteristics than the CPW structure when there is occurred the variation between the feed-line and the ground plane in the f...

ABSTR•CT.--I assessed patterns of allozymic variation in Larus argentatus (Herring Gulls), L. cachinnans (Yellow-legged Herring Gulls), L. fuscus (Lesser Black-backed Gulls), L. glaucoides (Iceland Gull), L. hyperboreus (Glaucous Gulls), and L. marinus (Greater Black-backed Gull). I surveyed 34 presumed structural gene loci over 479 individuals. All birds were monomorphic and fixed for the same...

This paper reports on an experimental investigation of modes propagating along a conductor-backed slotline: the dominant mode, and the surface leaky mode. The measurement and the numerical experiments performed in the CST Microwave Studio verify theoretical findings of modes obtained by the method of moments applied in the spectral domain. The dispersion characteristic of the dominant mode on t...

BACKGROUND Currently, the use of metal-backed tibial components is more common than the use of all-polyethylene components in total knee arthroplasty. However, the available literature indicates that all-polyethylene tibial components are not inferior to the metal-backed design. We hypothesized that there would be no difference in the ten-year survival rate between all-polyethylene and metal-ba...
