Steven Bryant’s Solace: a conductor’s analysis and performance guide
No full textThe purpose of this study was to examine Solace, a musical composition for wind ensemble, by Steven Bryant composed for the University of North Carolina at Greensboro Wind Ensemble and premiered at the 2013 College Band Directors National Association National Conference. Through a conductor's analysis and performance guide, the author provided insight and background knowledge to all future performers and interpreters of the work through unique first hand accounts from commission to premiere performance. The research method included three processes: 1. A detailed analysis of the musical score, 2. The observation of rehearsals and recording sessions during preparation for the premiere performance of Solace by the University of North Carolina at Greensboro Wind Ensemble, Kevin M. Geraldi, conductor, 3. Extensive interviews of Steven Bryant, composer and Kevin M. Geraldi, conductor. Through examination of prior research on electro-acoustic works for wind ensemble, the author examined Solace within those constructs. Because of the blurring of lines between electronics and acoustic sound, the author further identified Solace as a unique musical composition within the electro-acoustic genre
Unified mathematical treatment of complex cascaded bipartite networks: The case of collections of journal papers
No full textIn this study, a mathematical treatment is proposed for analysis of entities and relations among entities in
complex networks consisting of cascaded bipartite networks. This treatment is applied to the case of
collections of journal papers. In this case, entities are distinguishable objects and concepts, such as papers,
references, paper authors, reference authors, paper journals, reference journals, institutions, terms, and term
definitions. Relations are associations between entity-types such as papers and the references they cite, or
paper authors and the papers they write. An entity-relationship model is introduced that explicitly shows
direct links between entity-types and possible useful indirect relations. From this a matrix formulation and
generalized matrix arithmetic are introduced that allow easy expression of relations between entities and
calculation of weights of indirect links and co-occurrence links. Occurrence matrices, equivalence
matrices, membership matrices and co-occurrence matrices are described. A dynamic model of growth
describes recursive relations in occurrence and co-occurrence matrices as papers are added to the paper
collection. Graph theoretic matrices are introduced to allow information flow studies of networks of papers
linked by their citations. Similarity calculations and similarity fusion are explained. Derivation of feature
vectors for pattern recognition techniques is presented. The relation of the proposed mathematical
treatment to seriation, clustering, multidimensional scaling, and visualization techniques is discussed. It is
shown that most existing bibliometric analysis techniques for dealing with collections of journal papers are
easily expressed in terms of the proposed mathematical treatment: co-citation analysis, bibliographic
coupling analysis, author co-citation analysis, journal co-citation analysis, Braam-Moed-vanRaan (BMV)
co-citation/co-word analysis, latent semantic analysis, hubs and authorities, and multidimensional scaling.
This report discusses an extensive software toolkit that was developed for this research for analyzing and
visualizing entities and links in a collection of journal papers. Additionally, an extensive case study is
presented, analyzing and visualizing 60 years of anthrax research through a collection of journal papers.
When dealing with complex networks that consist of cascaded bipartite networks, the treatment presented
here provides a general mathematical framework for all aspects of analysis of static network structure and
network dynamic growth. As such, it provides a basic paradigm for thinking about and modeling such
networks: computing direct and indirect links, expressing and analyzing statistical distributions of network
characteristics, describing network growth, deriving feature vectors, clustering, and visualizing network
structure and growth
Composite Constructions of Self-Dual Codes from Group Rings and New Extremal Self-Dual Binary Codes of Length 68
No full textThis is a pre-copy-editing, author-produced PDF of an article accepted for publication in Advances in Mathematics of Communications following peer review. The definitive publisher-authenticated version Dougherty, S, T., Gildea, J., Korban, A. & Kaya, A. (2019 - forthcoming). Composite Constructions of Self-Dual Codes from Group Rings and New Extremal Self-Dual Binary Codes of Length 68. Advances in Mathematics of Communications, is available online at: 10.3934/amc.2020037.We describe eight composite constructions from group rings where the orders of
the groups are 4 and 8, which are then applied to find self-dual codes of length 16 over
F4. These codes have binary images with parameters [32, 16, 8] or [32, 16, 6]. These
are lifted to codes over F4 + uF4, to obtain codes with Gray images extremal self-dual
binary codes of length 64. Finally, we use a building-up method over F2 + uF2 to
obtain new extremal binary self-dual codes of length 68. We construct 11 new codes
via the building-up method and 2 new codes by considering possible neighbors

(CJF); idem, Parque Nacional de Doñana, Bujalance <i>et al.</i> (2016) (11 exx, CJLB).</p> <p> <b>Diagnosis</b>: Unmistakable species among the Iberian <i>Tentyria</i> by having the following features: black body, sub-cylindrical (Fig. 200), about 13.2 mm in average length, not very bright and very finely punctured; large and broad head (Fig. 14), sub-triangular epistome, with a well-developed tooth in the middle; barely convex eyes; wide, deep, and very well defined gular groove (Fig. 49). Pronotum (Fig. 83) provided with a very fine puncture; usually slightly transverse, and sub-cordiform, sometimes subcircular or sub-elliptical and more transverse, with the base straight or sub-straight, not sinuous before the posterior angles and generally something narrower than the apex. Elongated and medially depressed prosternal apophysis (Fig. 119), surpassing the level of the procoxae. Elytra oval elongated, variable in length, subcylindrical, sometimes slightly striated and somewhat broader than the pronotum. Small aedeagus, fusiform parameres and barely longer than phallobase (Fig. 167).</p> <p> <b>Comments</b>: Species described from “Lusitania”, not from Andalusia as Viñolas & Catagena (2005) mentioned. Steven (1828) described <i>Tentyria platyceps</i> with at least one specimen from “Lusitania” (MNHUB). Data on the Steven’s description agrees with the label that carries one of the syntypes listed as <i>T. curculionoides</i> Herbst in the Berlin Museum, before to be rectified and attributed to “ <i>T. curculioides</i> Ht. *” (Fig. 231). This confusion is the reason of that the type of <i>T. platyceps</i> Steven has remained hidden to date, not appearing in the recording book of the Museum.</p> <p> Accordingly, <i>T. platyceps</i> Steven was an unknown species to Solier (1835) and Rosenhauer (1856). Hence these authors described <i>T. goudoti</i> Solier (Fig. 232) and <i>T. modesta</i> Rosenhauer (Fig. 233), with identical characters those of <i>T. platyceps</i> Steven, as indicated Kraatz (1865) and Schaum (1862) respectively. This verifies that these last authors knew the true identity of <i>T. platyceps</i> Steven, by intuiting the confusion between <i>T. curta</i> Steven and <i>T. curculionoides</i> Herbst (Kraatz 1865). From Kraatz (1865), <i>T. platyceps</i> Steven has been a species correctly interpreted by almost all authors.</p> <p> Reitter (1900), described <i>T. calcarata</i> from Malaga, which was, dubiously, considered synonymy of <i>T. platyceps</i> Steven by Español (1960), since it was the unique species of <i>Tentyria</i> present in the mentioned locality whose description fits to that Reitter gave, even when this author does not include it in the group 3, close to <i>T. platyceps</i> Steven.</p> <p> Later, Kaszab designated in litt. “ Holotypus ” of <i>T. calcarata</i> Reitter a specimen from the MNHN labelled from Malaga (Fig. 234), and which corresponds to a variant specimen of the <i>T. platyceps</i> Steven (with the pronotum very transverse, and sub-elliptical), like the syntypes of <i>Tentyria platyceps</i> v. <i>modesta</i> Rosenhauer.</p> <p> <b> Designation of the Lectotype <i>Tentyria platyceps</i> Steven, 1828, present designation</b> :</p> <p> The specimen of the typical series that bears the following labels (two of them old): small rectangular label, “45574” / big square label, “ <i>Orbiculata Akis</i> F., <i>curculioides</i> Ht. *, <i>Ten. Nomas</i> Pall., Lusit” / red label, “ SYNTYPUS <i>Pimelia curculionoides</i> Herbst, 1799 labelled by NMHUB 2006” / white, “Hist.-Col. (Coleoptera), Nr. 45574, <i>Tentyria curculionoides</i> Herbst, Lusitan., Zool. Mus. Berlin ”, is designated Lectotype (Fig. 231). The remaining syntypes are designated “ Paralectotypes ”.</p> <p> <b> Designation of the Lectotype of <i>Tentyria goudoti</i> Solier, 1835, present designation:</b> </p> <p> The unique syntype of <i>Tentyria goudoti</i> Solier, bearing the lables: “goudot, Tanger / Muséum Paris, Tanger, Goudot / <i>Tentyria goudoti</i> Sol. / Type”, is designated Lectotype (Fig. 232).</p> <p> <b> Designation of Lectotype and Paralectotype of <i>Tentyria modesta</i> Rosenhauer, 1856, present designation:</b> </p> <p> To provide taxonomic stability, we consider necessary to designate Lectotype and Paralectotype of <i>Tentyria modesta</i> Rosenhauer to each of the two specimens examined in the MNHN, bearing the Rosenhauer’s labels and fitting to the description of this author, although they do not appear as syntypes. The specimen that bears the following labels: “ <i>T. platyceps</i> v. <i>modesta</i> Rosh. Hispania / <i>T. platyceps</i> v. <i>modesta</i> Rosh. / Hispania Rosh.”, is designated Lectotype (Fig. 233); the other that carrying the label: “Hispania Rosh.”, is designated Paralectotype.</p> <p> <b>Geographical distribution:</b> Widely distributed in central and southern Iberian Peninsula, especially in the inner areas. <i>T. platyceps</i> Steven, has been also cited in the north of Morocco (Tánger) as <i>T. goudoti</i> Solier (1835), Escalera (1914) and Kocher (1958). The record of Algeria (Reitter 1900) needs to be verified due to the historical confusion of this taxon discussed above.</p> <p> <b> Group of <i>T. bassii</i></b> </p>Published as part of <i>Bujalance, José L., Ferrer, Julio & Cárdenas, Ana M., 2023, A taxonomic revision of the genus Tentyria Latreille, 1802 in the Iberian Peninsula and Balearic Islands (Coleoptera: Tenebrionidae), pp. 1-88 in Zootaxa 5320 (1)</i> on pages 29-31, DOI: 10.11646/zootaxa.5320.1.1, <a href="http://zenodo.org/record/8203747">http://zenodo.org/record/8203747</a>
Exploiting knowledge of immune selection in HIV-1 to detect HIV-specific CD8 T-cell responses
No full textSince HLA-restricted cytotoxic T-cell responses select specific polymorphisms in HIV-1 sequences and HLA diversity is relatively static in human populations, we investigated the use of peptide epitopes based on sites of HLA-associated adaptation in HIV-1 sequences to stimulate and detect T-cell responses ex vivo. These "HLA-optimised" peptides captured more HIV-1 Nef-specific responses compared with overlapping peptides of a single consensus sequence, in interferon-γ enzyme linked immunospot assays. Sites of immune selection can reveal more immunogenic epitopes in HLA-diverse populations and offer insights into the nature of HLA-epitope targeting, which could be applied in vaccine design

Algebraic coding theory over finite commutative rings
No full textThis book provides a self-contained introduction to algebraic coding theory over finite Frobenius rings. It is the first to offer a comprehensive account on the subject. Coding theory has its origins in the engineering problem of effective electronic communication where the alphabet is generally the binary field. Since its inception, it has grown as a branch of mathematics, and has since been expanded to consider any finite field, and later also Frobenius rings, as its alphabet. This book presents a broad view of the subject as a branch of pure mathematics and relates major results to other fields, including combinatorics, number theory and ring theory. Suitable for graduate students, the book will be of interest to anyone working in the field of coding theory, as well as algebraists and number theorists looking to apply coding theory to their own work
