About 70% of the beverage alcohol consumed in China annually is spirits. Recorded spirits make up most spirit consumption, but about 25% of total alcohol consumption (1.7 L pure alcohol per capita annually) is unrecorded spirits (bai jiu), either homemade or made in unregulated distilleries. In some parts of China, the consumption of unrecorded spirits is higher than average. This paper compare...

The flat bug genus Longitergus was established by Pham, Bai, Heiss & Cai (2013) with two species: L. productus and L. similis from Vietnam and with L. productus as its type species. Unfortunately, the name Longitergus Pham, Bai, Heiss & Cai (2013) was preoccupied by Longitergus Wang (1993), a subgenus Yezoceryx (Longitergus) Wang, 1993 in Ichneumonidae (Hymenoptera: Ichneumonoidea) based on typ...

We consider Perron solutions to the Dirichlet problem for quasilinear elliptic equation divA(x,∇u)=0 in a bounded open set Ω⊂Rn. The vector-valued function A satisfies standard ellipticity assumptions with 1<p<∞ and p-admissible weight w. show that arbitrary perturbations on sets of (p,w)-capacity zero continuous (and certain quasicontinuous) boundary data f are resolutive such coincide. As con...

The global financial crisis began with a financial meltdown in the United States in early 2008 and then it had spread to the rest of the world. In this paper we test whether the MENA equity market volatility presents a different behavior before and after the financial crisis of 2008. Using long range dependence techniques we test for long memory in the returns, absolute and squared returns of t...

The sign-real and the sign-complex spectral radius, also called the generalized spectral radius, proved to be an interesting generalization of the classical Perron-Frobenius theory (for nonnegative matrices) to general real and to general complex matrices, respectively. Especially the generalization of the well-known Collatz-Wielandt max-min characterization shows one of the many one-to-one cor...

The involvement of vascular endothelial injury with the pathophysiological process of heart failure has been identified. Baicalein (BAI), a flavonoid extracted from the root of Scutellaria baicalensis, is reported to exert antibacterial, antiviral, antithrombotic and antioxidant effects. The aim of the present study was to investigate the effects of BAI on lipopolysaccharide (LPS)‑induced vascu...

This paper reports on an extensive Monte Carlo study of seven residual-based tests of the hypothesis of no cointegration. Critical values and the power of the tests under the alternative of fractional cointegration are simulated and compared. It turns out that the Phillips-Perron t-test when applied to regression residuals is more powerful than Geweke-Porter-Hudak tests and the Augmented Dickey...

The n × n Brualdi-Li matrix Bn has recently been shown to have maximal Perron value (spectral radius) ρ among all tournament matrices of even order n, thus settling the conjecture by the same name. This renews our interest in estimating ρ and motivates us to study the Perron eigenvector x of Bn, which is normalized to have 1-norm equal to one. It follows that x minimizes the 2-norm among all Pe...
