The assessment of wind energy potential is generally based on the analysis statistical distribution observed speed short time resolution. Record periods observational data used in practice at sites interest are often very short, ranging from a few months to years. Predictions such small record likely be biased as it recognized that subject important interannual variability and long-term trends....

[1] In this paper, by using a dynamic model with synoptic eddy and low-frequency flow (SELF) interaction, we show that the SELF feedback is of significant importance for the formation of the AO/NAO in both winter and summer. Although background storm activity is significantly weaker in summer than that in winter, the positive SELF feedback associated with the AO/NAO mode in summer can be as str...

[1] Observed multidecadal variability (30 yr runningmeans, trends, and moving standard deviations) of the North Atlantic Oscillation (NAO) during the instrumental record is compared to that simulated by two different coupled general circulation models in extended-range control experiments. Simulated NAO exhibits strong low frequency fluctuations, even on multi-centennial time scale. Observed mu...

  Background & Objectives: Antisense peptide nucleic acids (PNA) that target growth essential genes show potent bactericidal properties without cell lysis. We considered the possibility that whether PNA treatment influence the bacteria total nucleic acids content and apply approach to develop a new delivery system to Dendritic cells (DCs). DCs are the most potent antigen presenting cells in th...

The combined influence of the North Atlantic Oscillation (NAO) and East (EA) patterns on covariability temperatures precipitation in 35 stations Iberian Peninsula during period 1950–2019 is analysed this work. Four EA-NAO composites were defined from teleconnection patterns’ positive negative phases: EA+NAO+, EA+NAO-, EA-NAO+ EA-NAO-. Daily data maximum minimum temperature used to obtain season...

The paper presents a multimodal conversational interaction system for the Nao humanoid robot. The system was developed at the 8th International Summer Workshop on Multimodal Interfaces, Metz, 2012. We implemented WikiTalk, an existing spoken dialogue system for open-domain conversations, on Nao. This greatly extended the robot’s interaction capabilities by enabling Nao to talk about an unlimite...

Based on reanalysis and ensemble hindcasts data, this work investigates the multidecadal variation in seasonal predictability of Pacific-North American (PNA) teleconnection pattern during winter its sources. The results show that at two ends 20th century, PNA is mostly driven by El Niño-Southern Oscillation (ENSO), a good prediction expected if models can accurately predict PNA-ENSO relationshi...

This work is set out to quantify the contribution of tropical and extratropical atmospheric forcing mechanisms to the formation of the North Atlantic Oscillation (NAO) pattern. Although the NAO varies on a wide range of time scales, we focus on 10 60 d. At these time scales, mechanisms are at play in the atmosphere that can generate the characteristic dipole pattern. We focus on the tropical Ro...

1. The North Atlantic Oscillation (NAO) exerts considerable control on U.K. weather. This study investigates the impact of the NAO on butterfly abundance and phenology using 34 years of data from the U.K. Butterfly Monitoring Scheme (UKBMS).2. The study uses a multi-species indicator to show that the NAO does not affect overall U.K. butterfly population size. However, the abundance of bivoltine...

We have tested the inhibitory potential of peptide nucleic acid (PNA) on in vitro reverse transcription of the HIV-1 gag gene. PNA was designed to target different regions of the HIV-1 gag gene and the effect on reverse transcription by HIV-1, MMLV and AMV reverse transcriptases (RTs) was investigated. We found that a bis-PNA (parallel antisense 10mer linked to antiparallel antisense 10mer) was...
