Macrolibnetis Pic 1938
No full textGenus Macrolibnetis Pic, 1938 Macrolibnetis Pic, 1938: 280. Type species: Macrolibnetis depressus Pic, 1938 (by monotypy). Remarks. The genus Macrolibnetis Pic, 1938 was separated by the author of the taxon from the similar Platerodrilus Pic, 1921 only by the relatively smaller head, longer narrow antennae and wider in distal portion elytra (Pic, 1938), but was placed in a different family, Lycidae, whereas Platerodrilus in Pic’s opinion belonged to Drilidae. Macrolibnetis was synonymized with Platerodrilus after its holotype was studied (Bocakova, 2001), but was reinstated later based on the data provided by molecular analyses (Bocak & Bocakova, 2008; Masek & Bocak, 2014). Only one species is described in this genus.Published as part of Kazantsev, Sergey V., 2021, New and little known taxa of neotenic lyropaeine net-winged beetles (Coleoptera Lycidae), pp. 437-460 in Zootaxa 4965 (3) on page 442, DOI: 10.11646/zootaxa.4965.3.2, http://zenodo.org/record/475266

2022 taxonomic update of phylum Negarnaviricota (Riboviria: Orthornavirae), including the large orders Bunyavirales and Mononegavirales
No full textIn March 2022, following the annual International Committee on Taxonomy of Viruses (ICTV) ratification vote on newly proposed taxa, the phylum Negarnaviricota was amended and emended. The phylum was expanded by two new families (bunyaviral Discoviridae and Tulasviridae), 41 new genera, and 98 new species. Three hundred forty-nine species were renamed and/or moved. The accidentally misspelled names of seven species were corrected. This article presents the updated taxonomy of Negarnaviricota as now accepted by the ICTV.Instituto de Patología VegetalFil: Kuhn, Jens H. National Institute of Allergy and Infectious Diseases.

Structure, transcription and variability of metazoan mitochondrial genome: perspectives from an unusual mitochondrial inheritance system
No full textDespite its functional conservation, mtDNA presents strikingly different features among eukaryotes, such as size, rearrangement frequency, and amount of intergenic regions. The reasons beyond this diversity have been object of extensive studies that have investigated the correlation between different mtDNA evolutionary patterns and body mass, metabolic rate, reactive oxygen species production, lifespan, etc. The fundamental role of non-adaptive processes such as random genetic drift and mutation rate in genome evolution has been recently highlighted by the work of several Authors. Under this light, mitochondrial bottlenecks and number of germ line replications are critical factors for mtDNA evolution, and different patterns of germ line differentiation could be responsible for the mtDNA diversity observed across eukaryotic lineages. Among metazoans, bivalve mollusc mtDNAs show unusual features, like hypervariable gene arrangement, high mutation rate, large amount of intergenic regions and, in some species, an unique inheritance system, the Doubly Uniparental Inheritance (DUI). In DUI species, two mitochondrial lineages are present: one is transmitted maternally (F-type), the other paternally (M-type). We exploited the DUI species Ruditapes philippinarumto study intergenic mtDNA functions, and to assess mitochondrial transcription and polymorphism in gonads. The coupling of high mutation rate with quite large genomes (i.e., large proportion of intergenic DNA) would be in contrast with the Mutation Pressure theory, but this is not true if most of that intergenic DNA has a function. We observed the presence of conserved functional elements and novel ORFs that could explain the evolutionary persistence of such regions and possibly be involved in DUI-specific aspects. Accordingly, the RNA-Seq analysis showed that mtDNA transcription is lineage-specific and it is independent from the nuclear background. This is consistent with an involvement in transcriptional control of the lineage- specific structures found inside the intergenic regions. We also found that male-transmitted and female- transmitted mtDNAs have a similar amount of polymorphism, but of a different kind. In contrast with organisms that show male-driven evolution, in this species male and female germ cells undergo a similar number of replication events due to gonad physiology, and this is reflected by the number of SNPs in M and F mtDNAs. The different kind of polymorphism is instead an effect of a different population size (different bottlenecks) and of a different efficiency of selection on the two mitochondrial lineages. Our results are consistent with the hypothesis that mtDNA evolution is strongly dependent on the dynamics of germ line formation. The DUI system offers the possibility to study the evolutionary dynamics of mtDNAs that, despite being in the same organism, experience different genetic drifts (due to different mitochondrial population size in gametes), but also different selective pressures. Actually, DUI animals are the only known organisms in which the mtDNA (i.e. the M-type) is subject to selection for male function. In a broadcast spawning organism the performance of spermatozoa is extremely important and selection for viable sperm, as well as sperm competition, is more efficient on a mtDNA which is transmitted through males. For this reason, we think that even if DUI probably arose by chance through completely stochastic events, its evolutionary persistence may be adaptive, because an increased male fitness would be beneficial for the whole species

‘The Noblest Soul’: A Sad Page in the History of the Grand Duchy of Hesse through the Eyes of Grand Duke Sergey Alexandrovich. The Darmstadt Diary, 1892
No full textThis is the first publication of a fragment of the diary of Grand Duke Sergey Alexandrovich of Russia for 1892 describing illness, death, and burial of Grand Duke Ludwig IV of Hesse and by Rhine, head of one of the states forming a part of the German Empire. Ever since the 18th century the Russian Imperial Family was bound by close kinship to the Hessian ducal family. The author of the diary was a member of the House of the Romanovs, a younger brother of Russian Emperor Alexander III. Grand Duke Sergey Alexandrovich held the post of the Moscow Governor-General. In 1884 he married Grand Duchess Elizabeth Feodorovna, n?e Princess of Hesse, who was a daughter of Grand Duke Ludwig IV. This publication includes diary records from February 26 to March 9, 1892, covering the time when Grand Duke Sergey Alexandrovich and his wife were staying in Darmstadt. The diary describes the daily life of the Royal family in the capital of the Grand Duchy of Hesse and by Rhine during said period and the participation in the obsequies of the deceased’s family and the representatives of the Russian, British and German ruling dynasties. Among others, the Grand Duke Sergey Alexandrovich’s diary mentions German Dowager Empress Victoria (the mother of Emperor Wilhelm II), Prince Henry of Prussia (the future Grand Admiral of the Imperial German Navy), Prince Louis Battenberg (the future British First Sea Lord), Princess Alice of Hesse, the younger sister of Grand Duchess Elizabeth Feodorovna, future Russian Empress Alexandra Feodorovna. The daily entries record family unity of the members of the Russian, the German, and the British Royal dynasties in the face of common tragedy against the backdrop of difficult relations between their empires. The deceased, Grand Duke Ludwig IV, enjoyed universal respect. Diaries of Grand Duke Sergey Alexandrovich are stored in his personal provenance fond in the State Archive of the Russian Federation (Moscow).</jats:p

Lock-in amplifier with a high common-mode rejection ratio in the range of 0.02 to 100 kHz
No full textThis is an open-access article distributed under the terms of the Creative Commons Attribution 3.0 License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. The paper presents a new lock-in amplifier with a differential input. The lock-in amplifier has a high common-mode rejection ratio of 200 dB at 1 kHz and 160 dB in the frequency range of 20 Hz to 100 kHz. A method for extending the dynamic range of comparing signals is suggested. The experimental results of metrological characteristic tests are discussed. © 2019 IMEKO
