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...

Motivation: Network alignment (NA) can be pairwise (PNA) and multiple (MNA). PNA produces aligned node pairs between two networks. MNA produces aligned node clusters between more than two networks. Recently, the focus has shi‰ed from PNA to MNA, because MNA captures conserved regions between more networks than PNA (and MNA is thus considered to be more insightful), though at higher computationa...

Charge transfer (CT) properties are compared between peptide nucleic acid structures with an aminoethylglycine backbone (aeg-PNA) and those with a γ-methylated backbone (γ-PNA). The common aeg-PNA is an achiral molecule with a flexible structure, whereas γ-PNA is a chiral molecule with a significantly more rigid structure than aeg-PNA. Electrochemical measurements show that the CT rate constant...

Elevated blood pressure (BP) is the most common cause of cardiovascular disease. Salt intake has a strong influence on BP, and plasma sodium (pNa) is increased with progressive increases in salt intake. However, the associations with pNa and BP had been reported inconsistently. We evaluated the association between pNa and BP, and estimated the risks of all-cause-mortality according to pNa level...

Incorporation of a guanidine functional group into the PNA backbone facilitates cellular uptake of PNA into mammalian cells with efficiency comparable to that of the TAT transduction domain. The modified PNA recognizes and binds to the complementary DNA strand in accordance with Watson-Crick recognition rules. However, unlike polypyrimidine PNA which binds to DNA in 2:1 stoichiometry, the modif...
