Stock market returns are signi…cantly higher on days when important macroeconomic news, such as that about in ‡ation, unemployment, or interest rates, is scheduled for announcement. The average announcement day excess return from 1958 to 2008 is 10.6 basis points versus 1.0 basis points for all the other days, suggesting that over 60% of the cumulative(More)
To date there are no clear criteria to determine whether a microbe is susceptible to biocides or not. As a starting point for distinguishing between wild-type and resistant organisms, we set out to determine the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) distributions for four common biocides; triclosan, benzalkonium(More)
Intrinsically resistant bacteria have emerged as a relevant health problem in the last years. Those bacterial species, several of them with an environmental origin, present naturally low-level susceptibility to several drugs. It has been proposed that intrinsic resistance is mainly the consequence of the impermeability of cellular envelopes, the activity of(More)
Stenotrophomonas maltophilia is an emerging multi-drug-resistant global opportunistic pathogen of environmental, mainly plant-associated origin. It is also used as a biocontrol or stress protecting agent for crops in sustainable agricultural as well as in bioremediation strategies. In order to establish effective protocols to distinguish harmless from(More)
High-Efficiency Video Coding (HEVC) was conceived by the Joint Collaborative Team on Video Coding as the natural successor of the H.264/AVC standard, which has been the most extended digital video standard in all segments of the domestic and professional markets for over 10 years. HEVC roughly doubles the compression performance of H.264/AVC in(More)
Bacterial multidrug efflux pumps are antibiotic resistance determinants present in all microorganisms. With few exceptions, they are chromosomally encoded and present a conserved organization both at the genetic and at the protein levels. In addition, most, if not all, strains of a given bacterial species present the same chromosomally-encoded efflux pumps.(More)
The effect of meta-Topolin (mT), an aromatic natural cytokinin, on micropropagation and adventitious shoot regeneration was evaluated on Prunus rootstocks, Torinel (Prunus domestica L.) and Ferdor (Prunus insititia  ×  domestica). In vitro shoots were grown for three subcultures on a multiplication medium containing 2.1, 4.2 or 6.3 μM of mT or 2.1 µM N(More)
Over the past years, multimedia usage has changed dramatically, with networks and terminals of diverse bandwidths and capabilities coexisting, making an adaptability of the video stream necessary. By the use of video scalability schemes, video streams would be able to adapt to these heterogeneous networks and a wide range of terminals. Moreover, some(More)
The widely used biocide triclosan selectively targets FabI, the NADH-dependent trans-2-enoyl-acyl carrier protein (ACP) reductase, which is also an important target for the development of narrow spectrum antibiotics. The analysis of triclosan resistant Staphylococcus aureus isolates had previously shown that in about half of the strains, the mechanism of(More)
