The Discovery of Black Light

|This article is the beginning of a reexpresson, and partial revision, of my book Black Light. The questions that I discuss in this article are listed in the below list of sections. In Sections 7, 8, 27, and 28, I discuss my discovery of black light. |The theoretical discovery of black light (that is, the thought experimental discovery of black light): The black spatial field in, for example, a “dark” room is actually, I argue, black light; and it is emitted from everything in the spatial field of the room (that is, the relatively empty space, and all objects). If, hypothetically, the black light in the above room was removed, we, when we would look into the spatial field of the room, would be blind, despite that we have the capacity to see. |The observational discovery of black light: There is no such thing as a “colorless” visual field for observers: A “colorless” visual field would be a visual field of blindness for observers, despite that they have vision, and that their eyes would be open. The black visual field is not, as is commonly stated, “the absence of photons”, “the absence of visible light”, and the, as such, absence of color: If it were, then it would be “colorless” (that is, not black), and, as such, a visual field of blindness for observers. |The experimental confirmation of black light via neurophysics: In Section 28, I demonstrate that particular EEG experimentation that was done on test-subjects in various conditions provides evidence or proof that the black of the black visual field that strikes our retinas is black light.

Unsupervised classification of SARS-CoV-2 genomic sequences uncovers hidden genetic diversity and suggests an efficient strategy for genomic surveillance

Accurate and timely monitoring of emerging genomic diversity is crucial for limiting the spread of potentially more transmissible/pathogenic strains of SARS-CoV-2. At the time of writing, over 1.8M distinct viral genome sequences have been made publicly available, and a sophisticated nomenclature system based on phylogenetic evidence and expert manual curation has allowed the relatively rapid classification of emerging lineages of potential concern. Here, we propose a complementary approach that integrates fine-grained spatiotemporal estimates of allele frequency with unsupervised clustering of viral haplotypes, and demonstrate that multiple highly frequent genetic variants, arising within large and/or rapidly expanding SARS-CoV-2 lineages, have highly biased geographic distributions and are not adequately captured by current SARS-CoV-2 nomenclature standards. Our results advocate a partial revision of current methods used to track SARS-CoV-2 genomic diversity and highlight the importance of the application of strategies based on the systematic analysis and integration of regional data. Here we provide a complementary, completely automated and reproducible framework for the mapping of genetic diversity in time and across different geographic regions, and for the prioritization of virus variants of potential concern. We believe that the approach outlined in this study will contribute to relevant advances to current genomic surveillance methods.

Partial revision of the genus Robinsonia Grote 1866: description of five new species for the Neotropical fauna (Lepidoptera, Erebidae, Arctiinae, Phaegopterina)

The genus Robinsonia Grote, 1866 is partially reviewed following a large DNA barcode campaign. In the Robinsonia praphoea Dognin, 1906 group three new species are described: R. simulans sp. n. from French Guiana, up to now confused with R. praphoea itself and then R. decaensi sp. n. and R. maranhensis sp. n. both from the lower Amazon. R. drechseli sp. n. is described from Paraguay and R. inexpectata sp. n., a species close to R. mera (Schaus, 1910) from Costa Rica, is described as new from Peru and Bolivia. Finally the full species status is confirmed for R. flavicorpus Dognin, 1910 which is found to be differentiable from R. marginata Rothschild, 1909. All types are figured along with the male genitalia for most and some female genitalia for all studied species.

Construction Method of Tender Document Based on Case-based Reasoning

The core activities of tender documents compilation are to collect similar historical tender documents, select compilation templates of tender documents and revise templates of tender documents partially. However, when the historical tender documents have accumulated to a certain amount, it becomes extremely difficult for compilers to summary, reuse and revise templates artificially in traditional compiling methods. Based on casebased reasoning (CBR), this paper studied the content recommendation method in the process of tender document construction. Firstly, a structured model of tender documents was constructed, and similar tender cases were retrieved from the tender case database according to the characteristics of tender cases; Secondly, the non-interference sequence index was used to measure the similarity of clauses used in similar tender cases, and the recommended sequences of reference template and content module of tender documents were constructed, which realized the recommendation of compiling templates of tender documents and partial revision of templates; Finally, the knowledge of the new tender case was updated. The empirical analysis shows that the construction method of tender documents based on case-based reasoning not only proposes a suitable strategy for compiling tender documents, but also improves the compilation efficiency of tender documents.

Advanced Russian EFL Learners’ Awareness of Idiomatic Synonymy, Antonymy, and Polysemy

Foreign language acquisition is notoriously constrained by learners’ lack of awareness of the systemic relations that are obtained among stable multiple-unit lexical items. This results in learners’ inability to variegate their performance (both written and oral) with idioms that stand in complementary (synonymy) or contrastive (antonymy) distribution to one another. Nor are learners typically able to distinguish between the multiple senses of English idioms. Given these impedimenta, the present research investigates the degree of entrenchment of idiomatic synonymy, antonymy, and polysemy and, on the back of it, sets the agenda for partial revision of the practice of exposing learners to English idioms. Data were collected to investigate the knowledge of idiomatic synonymy, antonymy, and polysemy amongst Russian EFL learners. The results of the ANOVA analysis revealed that the degree of awareness of the major types of idiomatic paradigmatic relations significantly differed between the groups, with learners being more aware of synonymy and polysemy than antonymy. The findings suggest that current EFL materials and dictionaries need to be updated and revisited with a view to exposing foreign learners to an extended network of paradigmatic idiomatic relations.

Partial revision of the Afrotropical Ballini, with the description of seven new genera (Araneae: Salticidae)

The jumping spider tribe Ballini is reviewed in the Afrotropical Region. The genera Afromarengo Benjamin, 2004 and Goleta Peckham & Peckham, 1894 are redefined. In Afromarengo, A. coriacea (Simon, 1900) is illustrated and A. ghanaensis sp. nov. (♀, from Ghana) and A. ugandensis sp. nov. (♂♀, from Uganda and D.R. Congo) are newly described. For Goleta, the type species, Goleta workmani (Peckham & Peckham, 1885), is redescribed from both sexes. Seven new genera and twelve new species are described, including three monotypic genera, Ballagascar gen. nov., with B. insularis (Peckham & Peckham, 1885) comb. nov. (ex Colaxes Simon, 1900) from Madagascar (♂♀) as the type species; Mondeku gen. nov., with M. albopilosum sp. nov. (♂♀, from Kenya) as the type species; and Oviballus gen. nov., with O. vidae sp. nov. (♂♀, from South Africa) as the type species. We also describe Planamarengo gen. nov., with P. bimaculata (Peckham & Peckham, 1903) comb. nov. (ex Afromarengo) from South Africa (♂♀) as the type species, as well as P. gatamaiyu sp. nov. (♂, from Kenya) and P. kenyaensis sp. nov. (♂♀, from Kenya); Propiomarengo gen. nov., with P. plana (Haddad & Wesołowska, 2013) comb. nov. (ex Afromarengo) from South Africa (♀) as the type species, as well as P. foordi sp. nov. (♂, from South Africa); Tenuiballus gen. nov., with T. minor sp. nov. (♂, from South Africa) as the type species, and also including T. coronatus sp. nov. (♂, from South Africa); and Wandawe gen. nov., with W. benjamini (Wesołowska & Haddad, 2013) comb. n. (ex Colaxes) from South Africa (♂♀) as the type species, and also including W. australe sp. nov. (♂♀, from South Africa) and W. tigrinа sp. nov. (♂♀, from Kenya and Uganda). A new combination for Copocrossa albozonata Caporiacco, 1949, Afromarengo albozonata comb. nov. is provided, and the name A. albozonata is treated as a nomen dubium. A new species of Padilla Peckham & Peckham, 1894, a genus only known from the Afrotropical Indian Ocean islands, P. wandae sp. nov. (♂♀, from Madagascar), is described. New data and illustrations for Sadies Wanless, 1984, as well as two Asian species of Colaxes, are provided. The recently revised Pachyballus Simon, 1900 and Peplometus Simon, 1900 are not treated further. A key to the genera of Afrotropical Ballinae is presented, as well as new data on their natural history, biogeography, and a discussion of the evolution of mimicry of various arthropod groups by balline jumping spiders. A putative synapomorphy and the new composition of Ballini sensu novo are proposed.

Anachronic Sonorities of Technoculture in Digital Games

The preliminary effort of this article consists in questioning some issues with the currently developed researches on the sound of digital games, in order to retrieve an approach capable of articulating communication, memory and culture, as a way to situate these extensively disseminated contemporary artefacts in a wider technocultural frame of reference. In order to achieve this goal, we propose a partial revision of prominent works dealing with the sonorities of digital games, contrasting them through the theoretical-methodological contributions of Walter Benjamin’s philosophy of the history and Media Archaeology. With this approach, which has important ethical-political consequences for the research in progress, we are able to reformulate questions being asked about the sounds of digital games, taking them instead as compelling objects for inquiries regarding our contemporary technoculture and a memory of media that surpasses them.
