Fauriea, a new genus of the lecanoroid caloplacoid lichens (Teloschistaceae, lichen-forming ascomycetes)

The robust monophyletic branch having the highest level of bootstrap support in the phylogenetical tree of the Teloschistaceae based on combined data set of ITS, LSU nrDNA and 12S SSU mtDNA sequences, which does not belong to any other earlier proposed genera of the subfamily Caloplacoideae, is described as the new genus Fauriea S. Y. Kondr., L. Lőkös et J.-S. Hur, gen. nova for lecanoroid South Korean Caloplaca chujaensis, and newly described Eastern Chinese Fauriea orientochinensis. Descriptions of the new genus Fauriea and the species Fauriea orientochinensis, a comparison with closely related taxa and a discussion of their position are provided. New name Tayloriellina is proposed for the genus of the subfamily Brownlielloideae Tayloriella S. Y. Kondr., Kärnefelt, A. Thell, Elix et Hur (nom. illeg., non Tayloriella Kylin, Rhodomebaceae, Rhodophyta). New combinations for type species of the genera Fauriea and Tayloriellina (i.e.: Fauriea chujaensis (basionym: Caloplaca chujaensis S. Y. Kondr., L. Lőkös et J.-S. Hur), and Tayloriellina erythrosticta (basionym: Lecanora erythrosticta Taylor)) are proposed. Fauriea chejuensis and Biatora pseudosambuci are for the first time recorded for China

Brownlielloideae, a new subfamily in the Teloschistaceae (Lecanoromycetes, Ascomycota)

Brownlielloideae, a new subfamily in the Teloschistaceae, is proposed based on phylogenetic analyses of nuclear ribosomal DNA and 12S SSU mitochondrial DNA sequences. The data indicates that the new subfamily includes eight genera, i.e. Brownliella, Marchantiana and six new genera proposed here, Lazarenkoella, Raesaeneniana, Streimanniella, Tarasginia, Tayloriella and Thelliana. Lecanora kobeana Nyl. is lectotypified and shown to be an older name for the type species of the genus Brownliella, B. aequata. In addition, a seventh new genus, Neobrownliella is proposed in the subfamily Teloschistoideae. This new genus and the new species, Thelliana pseudokiamae are described. 13 new combinations are proposed: Brownliella kobeana, Fulgogasparrea appressa, Lazarenkoella zoroasteriorum, Neobrownliella brownlieae, N. montisfracti, Raesaeneniana maulensis, Streimanniella burneyensis, S. kalbiorum, S. michelagoensis, S. seppeltii, Tarasginia tomareeana, T. whinrayi and Tayloriella erythrosticta

Advanced interface models for metal forming simulations

Friction and heat transfer in metal forming simulations are usually restricted by software to be interface constants, a situation not reflected by the mechanics of real manufacturing processes. A better simulation approach is to use a micromechanics based method to estimate friction and heat transfer as evolutionary phenomenon. This paper presents a friction and heat transfer module for hot forging simulations. The friction model is based on a lubricant film thickness calculation using the Reynolds equation, and a calculation of the fractional contact area based on asperity flattening and roughening. Friction is then portioned between asperity and lubricant contacts. Heat transfer coefficients are calculated using a new model for heat conduction through asperity contact patches and lubricant that takes into account the restriction to heat flow at the contacts. The program is implemented as a user routine in a popular commercially available finite element code, DEFORM 2D.Schmid, SR.; Liu, J.; Sellés Cantó, MÁ.; Pasang, T. (2013).

Model of Communities Isolation at Hierarchical Modular Networks

The model of community isolation was extended to the case when individuals are randomly placed at the nodes of hierarchical modular networks. It was shown that the average number of blocked nodes (individuals) increases in time as a power function, with the exponent depending on the network parameters. The distribution of the time when the first isolated cluster appears is unimodal, non-gaussian. The developed analytical approach is in a good agreement with the simulation data

Testing of adaptive nonuniform sampling switch algorithm with real-time simulation-in-the-loop

The study is motivated by the considerations concerning implementation of nonuniform sampling regarding the reallife objects. It is shown that nonuniform adaptive sampling switch algorithm can ensure a reduction in the number of taken samples and does not exert negative influence on the quality of the system control. Experiment was performed with 24VDC permanent magnet motor with encoder as a plant. Signals from the encoder were used for rotational speed calculations. The results of experiment are included
