Evidence for Positive Selection in the Capsid Protein-Coding Region of the Foot-and-Mouth Disease Virus (FMDV) Subjected to Experimental Passage Regi…

2001

We present sequence data from two genomic regions of foot-and-mouth disease virus (FMDV) subjected to several experimental passage regimens. Maximum-likelihood estimates of the nonsynonymous-to-synonymous rate ratio parameter (dN/dS) suggested the action of positive selection on some antigenic sites of the FMDV capsid during some experimental passages. These antigenic sites showed an accumulation of convergent amino acid replacements during massive serial cytolytic passages and also in persistent infections of FMDV in cell culture. This accumulation was most significant at the antigenic site A (the G-H loop of capsid VP1), which includes an Arg-Gly-Asp (RGD) cellular recognition motif. Our …

Pārstrādātie lis pendens noteikumi Eiropas Parlamenta un Padomes regulā Nr. 1215/2012 un to ietekme uz civilprocesu Eiropas Savienībā

2016

Lis pendens un saistīto prasību noteikumi ir viena no nozīmīgākajām Eiropas Savienības civilprocesa regulējuma sastāvdaļām, kas nepieciešama tā saucamās Brisele I regulas par jurisdikciju un spriedumu atzīšanu un izpildi mērķu sasniegšanai. Šie noteikumi ir instruments, ar kura palīdzību nepieļaut paralēlas tiesvedības par vienu un to pašu priekšmetu un kā izvairīties no nesavienojamiem, neizpildāmiem spriedumiem. Darba mērķis ir iepazīties ar noteikumu piemērošanas vēsturi dalībvalstīs, to pārstrādes iemesliem un vērtēt, kā pārstrādātās Brisele I regulas Nr.1215/2012 normatīvā regulējuma izmaiņas varētu izsaukt gan Eiropas Savienības tiesas judikatūras maiņu, gan nacionālo tiesu prakses ma…

Crafting the Commons: The Art of Selecting Conservative and Labour Parliamentary Candidates for the 2015 General Election

2015

International audience; Crafting the Commons: The Art of Selecting Conservative and Labour Parliamentary Candidates for the 2015 General ElectionThe selection of parliamentary candidates for the general election is one of the most crucial tasks carried out by local parties who have long enjoyed relative autonomy from party headquarters in this respect. But because the aggregate choices of individual local parties determine the composition of the parliamentary parties, the party leaderships in both parties have devised new strategies and rules allowing them to influence that choice. This is in order both to ensure both that future MPs are more in tune with the leadership line and that the so…

A NETWORK PERSPECTIVE ON CO-BRANDING CAMPAIGNS: EVIDENCE FROM THE FASHION INDUSTRY

Co-branding strategies have attracted increasing attention in the academic community over the last decades. Previous research privileged the analysis of co-branding campaigns by studying dyadic relationships between brands. Here, we take a network view to highlight the influence of the single companies' co-branding portfolio on partnership formation. From a theoretical perspective, the studies on co-branding analyze the process through which partner brands send a "signal" to consumers. Here, instead, we propose to look at partner selection as a process in which a signal, namely, the portfolio of previous co-branding campaigns, is sent from one brand to the others. In particular, we focus on…

Diverse partner selection with brood recombination in genetic programming

2018

The ultimate goal of learning algorithms is to find the best solution from a search space without testing each and every solution available in the search space. During the evolution process new solutions (children) are produced from existing solutions (parents), where new solutions are expected to be better than existing solutions. This paper presents a new parent selection method for the crossover operation in genetic programming. The idea is to promote crossover between two behaviourally (phenotype) diverse parents such that the probability of children being better than their parents increases. The relative phenotype strengths and weaknesses of pairs of parents are exploited to find out i…

Peer selection and influence : Students’ interest-driven socio-digital participation and friendship networks

2020

Digital technologies have been increasingly embedded in students’ everyday lives. Interest-driven socio-digital participation (ISDP) involves students’ pursuit of interests mediated by computers, social media, the internet, and mobile devices’ integrated systems.ISDPis likely to intertwine closely with young people’s social networks that has been scarcely studied quantitatively. To close this gap, the present paper investigated students’ peer selection and influence effects of the intensity of their ISDP and friendship networks. We collected two-wave data by administering a peer nomination to trace students’ friendship networks with peers and a self-reported questionnaire to examine student…

Designing P-Chirogenic 1,2-Diphosphinobenzenes at Both P-Centers Using P(III)-Phosphinites

2016

International audience; A new enantiodivergent synthesis of P-chirogenic 1,2-diphosphinobenzenes (DP*B) bearing the chirality on one or both phosphorus centers is reported using aryne chemistry. The principle is based on successive reactions of 1,2-dibromobenzene with sec-phosphide boranes, then DABCO to remove the borane, and finally with chlorophosphines or P(III)-chirogenic phosphinites. The efficiency of this synthesis was demonstrated by the stereoselective preparation of (S,S)-1,2-bis(o-anisylphenylphosphino)benzene. A comparison of DIPAMP and homochiral DP*B ligands in asymmetric Rh- or Pd-catalyzed reactions was reported.

Surfactant-Mediated Morphology and Photocatalytic Activity of α‑Ag2WO4 Material

2018

In the present work, the morphology (hexagonal rod-like vs cuboid-like) of an α-Ag2WO4 solid-state material is manipulated by a simple controlled-precipitation method, with and without the presence of the anionic surfactant sodium dodecyl sulfate (SDS), respectively, over short reaction times. Characterization techniques, such as X-ray diffraction analysis, Rietveld refinement analysis, Fourier-transform (FT) infrared spectroscopy, FT Raman spectroscopy, UV–vis spectroscopy, transmission electron microscopy (TEM), high-resolution TEM, selected area electron diffraction, energy-dispersive X-ray spectroscopy, field emission-scanning electron microscopy (FE-SEM), and photoluminescence emission…
