In silico Identification and Expression of Protocadherin Gene Family in Octopus vulgaris
No full textConnecting millions of neurons to create a functional neural circuit is a daunting challenge. Vertebrates developed a molecular system at the cell membrane to allow neurons to recognize each other by distinguishing self from non-self through homophilic protocadherin interactions. In mammals, the protocadherin gene family counts about 50 different genes. By hetero-multimerization, protocadherins are capable of generating an impressive number of molecular interfaces. Surprisingly, in the California two-spot octopus, Octopus bimaculoides, an invertebrate belonging to the Phylum Mollusca, over 160 protocadherins (PCDHs) have been identified. Here we briefly discuss the role of PCDHs in neural wiring and conduct a comparative study of the protocadherin gene family in two closely related octopus species, Octopus vulgaris and O. bimaculoides. A first glance at the expression patterns of protocadherins in O. vulgaris is also provided. Finally, we comment on PCDH evolution in the light of invertebrate nervous system plasticity

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Repeat Age Decomposition Informs an Ancient Set of Repeats Associated With Coleoid Cephalopod Divergence
No full textIn comparison with other molluscs and bilaterians, the genomes of coleoid cephalopods (squid, cuttlefish, and octopus) sequenced so far show remarkably different genomic organization that presumably marked the early evolution of this taxon. The main driver behind this genomic rearrangement remains unclear. About half of the genome content in coleoids is known to consist of repeat elements; since selfish DNA is one of the powerful drivers of genome evolution, its pervasiveness could be intertwined with the emergence of cephalopod-specific genomic signatures and could have played an important role in the reorganization of the cephalopod genome architecture. However, due to abundant species-specific repeat expansions, it has not been possible so far to identify the ancient shared set of repeats associated with coleoid divergence. By means of an extensive repeat element re-evaluation and annotation combined with network sequence divergence approaches, we are able to identify and characterize the ancient repeat complement shared by at least four coleoid cephalopod species. Surprisingly, instead of the most abundant elements present in extant genomes, lower-copy-number DNA and retroelements were most associated with ancient coleoid radiation. Furthermore, evolutionary analysis of some of the most abundant families shared in Octopus bimaculoides and Euprymna scolopes disclosed within-family patterns of large species-specific expansions while also identifying a smaller shared expansion in the coleoid ancestor. Our study thus reveals the apomorphic nature of retroelement expansion in octopus and a conserved complement composed of several DNA element types and fewer LINE families
Metastable Nanosized Diamond Formation from Fluid Systems
No full textThe model of nanosized diamond particles formation at metastable P-T parameters from fluid is presented. It explains the specific of CVD diamond synthesis gases mixtures and hydrothermal growth of diamond at low P-T parameters as well as it explains the geneses of metamorphic and magmatic nano- and microdiamond in the shallow depth Earth rocks and the genesis of interstellar nanodiamond formations in the space
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Notatka Nikołaja Grinkiewicza „O szkole” i teksty uzupełniające
No full textThe text corpus of the Grinkevich Research and Translation Project About the School, which had an active phase in 2014-2019, is considered. The sources of 9 texts are: 2 – the Alaskan Russian Church archive in the Library of Congress, 3 – N. Russel’s brochure, 4 – San Francisco newspapers; the note On the School by N. Grinkevich is supplemented, confirming the facts reported in it, by 2 testimonies of Dr. Russel himself (including the history of the creation of the note), 3 parts dedicated to the school student of Belarusian-Tlingit origin N. Savchenko (letters from his father Demian), 2 newspaper publications revealing Grinkevich’s ambiguous role. The obvious reason for the change in public position of this psalm reader, later a member of the Ecclesiastical Consistory of Alaska in relation to the problems of the church school was the inertial adherence to routine rules and procedures, official subordination and the desire to maintain position, but it was the promulgation of his note by the revolutionaries that probably led to his dismissal, already as an archpriest, from the Diocese of the Aleutians and Alaska.Rozpatrzono zbiór tekstów projektu badawczo-tłumaczeniowego Grinkiewicza „O szkole”, który miał aktywną fazę w latach 2014-2019. Źródłami 9 tekstów są: 2 – archiwum „Rosyjskiego Kościoła Alaski” w Bibliotece Kongresu USA, 3 – broszura N. Russela, 4 – gazety San Francisco; notatka N. Grinkiewicza „O szkole” jest uzupełniona, potwierdzając przedstawione w niej fakty, przez 2 relacje samego doktora Russela (w tym o historii powstania notatki), 3 części dedykowane uczniowi szkoły pochodzenia „białorusko-tlingickiego” N. Sawczenko (listy od jego ojca Demiana), 2 publikacje prasowe ujawniające niejednoznaczną rolę Grinkiewicza. Oczywistymi przyczynami „zmiany stanowiska” tego psalmisty, później członka Konsystorza Kościelnego Alaski w odniesieniu do problemów szkoły kościelnej były przestrzeganie rutynowych zasad i procedur, oficjalne podporządkowanie i chęć utrzymania pozycji. Dymisja protojereja – drugiej najważniejszej postaci eparchii Aleutów i Alaski – kojarzy nam się z ogłoszeniem jego notatki przez rewolucjonistów.Рассматривается корпус текстов Гринкевичского исследовательского и переводческого проекта «О школе», который имел активную фазу в 2014-2019 гг. Источниками 9 текстов служат: 2 – архив «Аляскинской русской церкви» в Библиотеке Конгресса США, 3 – брошюра Н. Русселя, 4 – сан-францисские газеты; заметку Н. Гринкевича «О школе» дополняют, подтверждая сообщенные в ней факты, 2 свидетельства самого доктора Русселя (в т. ч. об истории создания заметки), 3 части, посвященные ученику школы «белорусско-тлинкитского» происхождения Н. Савченко (письма его отца Демьяна), 2 газетные публикации, раскрывающие неоднозначную роль Гринкевича. Очевидными причинами «изменения позиции» этого псаломщика, позже члена Аляскинского духовного правления по отношению к проблемам церковной школы были следование рутинным правилам и процедурам, должностное подчинение и стремление сохранить положение.
