Evidence of gene orthology and trans-species polymorphism, but not of parallel evolution, despite high levels of concerted evolution in the major his…

2016

17 pages; International audience; The major histocompatibility complex (MHC) is a cornerstone in the study of adaptive genetic diversity. Intriguingly, highly polymorphic MHC sequences are often not more similar within species than between closely related species. Divergent selection of gene duplicates, balancing selection maintaining trans-species polymorphism (TSP) that predate speciation and parallel evolution of species sharing similar selection pressures can all lead to higher sequence similarity between species. In contrast, high rates of concerted evolution increase sequence similarity of duplicated loci within species. Assessing these evolutionary models remains difficult as related…

Individuality of movements in music--finger and body movements during playing of the flute.

2013

The achievement of mastery in playing a composition by means of a musical instrument typically requires numerous repetitions and corrections according to the keys and notations of the music piece. Nevertheless, differences in the interpretation of the same music piece by highly skilled musicians seem to be recognizable. The present study investigated differences within and between skilled flute players in their finger and body movements playing the same piece several times on the same and on different days. Six semiprofessional and four professional musicians played an excerpt of Mozart’s Flute Concerto No. 2 several times on three different days. Finger and body movements were recorded by …

The Pagami Creek smoke plume after long-range transport to the upper troposphere over Europe – aerosol properties and black carbon mixing state

2014

Abstract. During the CONCERT 2011 field experiment with the DLR research aircraft Falcon, an enhanced aerosol layer with particle linear depolarization ratios of 6–8% at 532 nm was observed at altitudes above 10 km over northeast Germany on 16 September 2011. Dispersion simulations with HYSPILT suggest that the elevated aerosol layer originated from the Pagami Creek forest fire in Minnesota, USA, which caused pyro-convective uplift of particles and gases. The 3–4 day-old smoke plume had high total refractory black carbon (rBC) mass concentrations of 0.03–0.35 μg m−3 at standard temperature and pressure (STP) with rBC mass equivalent diameter predominantly smaller than 130 nm. Assuming a cor…

Z dziejów kultury muzycznej w kościele parafialnym pw. św. Wawrzyńca męczennika w Starym Waliszowie

2016

Początki kultury muzycznej Starego Waliszowa związane są z tamtejszą świątynią pw. św. Wawrzyńca. Prawdopodobnie już w XVIII wieku istniała tam kapela muzyczna. Prowadzona była przez miejscowych nauczycieli, którzy byli jednocześnie organistami i kościelnymi. Na przełomie XIX i XX stulecia funkcję chórmistrza pełnił przez 37 lat Josef Ho1 mann. Za jego kadencji miejscowi muzycy włączyli się w ogólnoniemiecki ruch odnowy muzyki kościelnej. W 1905 roku odbył się w Starym Waliszowie walny zjazd członków Stowarzyszenia Cecyliańskiego Hrabstwa Kłodzkiego. W 1930 roku miejscowy zespół wokalno-instrumentalny liczył 18 chórzystów i 15 instrumentalistów. Począwszy od XVIII wieku nabożeństwom w Stary…

Nucleation mechanism for the direct graphite-to-diamond phase transition

2011

Graphite and diamond have comparable free energies, yet forming diamond from graphite is far from easy. In the absence of a catalyst, pressures that are significantly higher than the equilibrium coexistence pressures are required to induce the graphite-to-diamond transition. Furthermore, the formation of the metastable hexagonal polymorph of diamond instead of the more stable cubic diamond is favored at lower temperatures. The concerted mechanism suggested in previous theoretical studies cannot explain these phenomena. Using an ab initio quality neural-network potential we performed a large-scale study of the graphite-to-diamond transition assuming that it occurs via nucleation. The nucleat…

CASSCF/CASPT2 analysis of the fragmentation of H2 on a Pd4 cluster

2009

Two reactive pathways are described for the dissociative adsorption of a hydrogen molecule on a Pd4 pyramidal cluster, by using DFT/B3LYP and CASSCF/CASPT2 computational methods. Because of the different spin multiplicities of the cluster in the initial and final states, the reaction proceeds through a spin multiplicity change, which occurs close to the transition states. The activation energy values are very similar when the DFT method is used, whereas the CASPT2 calculations predict that the concerted mechanism is disfavored. © 2009 Wiley Periodicals, Inc.

Concerted Evolution of Multigene Families and Homoeologous Recombination

2012

The dynamism of genomes is one of the most thoroughly documented paradigms in the genomic era, envisaged by the cytogenetic school during middle decades of the twentieth century. Such dynamism refers not just to the evolutionary changes that take place across deep time but also to the myriad changes at different levels (from SNPs to large structural rearrangements) that shape and adjust genomes over a smaller time scale. This chapter reviews two of the many forces that provide genome dynamism in plants. These two forces, concerted evolution of multigene families and homoeologous recombination of hybridized genomes, in principle contribute to shape the plant genomes through opposite effects …
