TL;DR: In this article, the authors examined the driving forces and key success factors related to the increasing globalization of the wine industry and further analyzed the current competitive advantage positions of four Old and five New World wine producing countries.
Abstract: This paper examines the driving forces and key success factors related to the increasing globalization of the wine industry. It further analyzes the current competitive advantage positions of four Old and five New World wine producing countries. The group with the strongest sources of competitive advantage position includes the United States, Australia, and Chile. The group of countries with moderate competitive advantages includes Italy, Spain, Argentina and South Africa, and the countries with the weakest competitive advantages in the global wine industry are two traditional strongholds of wine production from the Old World: France and Germany. This competitive advantage scenario should be a wake-up call to many countries. The study offers three specific recommendations for wineries of all sizes in all nations. They are: (i) increased emphasis on market orientation, (ii) increased export assistance, (iii) managing trade barriers effectively.

TL;DR: In this article, the issue of duality violations in the VV−AA vacuum polarization function in the chiral limit was studied, and a model with an expansion in inverse powers of the number of colors, Nc, allowing us to consider resonances with a finite width was proposed.
Abstract: We study the issue of duality violations in the VV−AA vacuum polarization function in the chiral limit. This is done with the help of a model with an expansion in inverse powers of the number of colors, Nc, allowing us to consider resonances with a finite width. Due to these duality violations, the Operator Product Expansion (OPE) and the moments of the spectral function (e.g. the Weinberg sum rules) do not match at finite momentum, and we analyze this difference in detail. We also perform a comparative study of many of the different methods proposed in the literature for the extraction of the OPE parameters and find that, when applied to our model, they all fare quite similarly. In fact, the model strongly suggests that a significant improvement in precision can only be expected after duality violations are included. To this end, we propose a method to parameterize these duality violations. The method works quite well for the model, and we hope that it may also be useful in future determinations of OPE parameters in QCD.

TL;DR: In both sexes, participants living in the Midwest and West had significantly higher serum selenium concentrations than those living in South and Northeast geographical locations, and men in the 31-50 y age group had the highest mean serum selene concentration.

TL;DR: This study extracted fungal DNA from spores of Cronartium and its anamorphic genus Peridermium, causing severe economic and aesthetic damage to pines in forests and parks throughout the northern hemisphere.
Abstract: Species in Cronartium and its anamorphic genus Peridermium form a morphologically homoge- neous group of rust fungi that infect stems, branches, and cones of Pinus species in North and Central America, Asia, and Europe. Several species are im- portant forest pathogens, causing severe economic and aesthetic damage to pines in forests and parks throughout the northern hemisphere. Morphologi- cal characters have been used to distinguish among these rust fungi, but have proven inadequate for as- sessing phylogenetic relationships within the group. In this study, we extracted fungal DNA from spores

TL;DR: Electrostatically gated semiconducting monolayer molybdenum disulfide (MoS2) is placed atop a homogeneous self-assembled layer of core-shell CdSSe QDs, and efficient nonradiative Förster resonant energy transfer (FRET) from QDs into MoS2 is demonstrated.
Abstract: We investigate near-field energy transfer between chemically synthesized quantum dots (QDs) and two-dimensional semiconductors. We fabricate devices in which electrostatically gated semiconducting monolayer molybdenum disulfide (MoS2) is placed atop a homogeneous self-assembled layer of core–shell CdSSe QDs. We demonstrate efficient nonradiative Forster resonant energy transfer (FRET) from QDs into MoS2 and prove that modest gate-induced variation in the excitonic absorption of MoS2 leads to large (∼500%) changes in the FRET rate. This in turn allows for up to ∼75% electrical modulation of QD photoluminescence intensity. The hybrid QD/MoS2 devices operate within a small voltage range, allow for continuous modification of the QD photoluminescence intensity, and can be used for selective tuning of QDs emitting in the visible-IR range.
