Faces and Places in Fashion: Steven Stipelman
No full textPart presentation, part Q&A, FIT's "Faces & Places in Fashion" lecture series is an opportunity to connect students and the public alike to the pulse of the fashion industry in an open and conversational setting.Our first remote class featured Steven Stipelman, professor of Fashion design/art at FIT since 1993. Professionally, his career goes back more than 40 years. His first job was staff illustrator at Henri Bendel, one of the most fashion forward stores of the period. He drew all the newspaper and promotional ads. His next job, and perhaps the one he is most associated with was an illustrator for Women's wear Daily and "W" for more than 25 years. He illustrated major American and European collections - designer to couture. He worked with these designers often sketching the garments before they were ever made. He learned a great deal of how the collections were created as well as construction and fabrication.Steven's work has been printed internationally and some of his clients included Lord & Taylor, Marshall Field, Estee Lauder, Orlane, Yves St Laurent cosmetics, Bill Blass, Pierre Cardin, Christian Dior, Valentino, Tuleh, Blassport, Basile and Ralph Rucci. His work has appeared in many shows and exhibitions throughout the country. In 2007, he had a one-person exhibition, "Ethereal Elegance," at the Museum at FIT. He is the author of a textbook, "Illustrating Fashion - Concept to Creation." He would describe his work as giving an impression of movement through a spontaneity of brush strokes and washes of acrylic or watercolor. He wants his figures to always have an ethereal or swan-like look, as if they were floating across the page. The drawing should project an emotion that would make you want to feel that way rather than look that way
Matson, S. W. & Robertson, A. B. The UvrD helicase and its modulation by the mismatch repair protein MutL. Nucleic Acids Res. 34, 4089-4097
No full textUvrD is a superfamily I DNA helicase with well documented roles in excision repair and methyl-directed mismatch repair (MMR) in addition to poorly understood roles in replication and recombination.

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

Electromagnetics, Volume 1
No full textElectromagnetics, volume 1 by Steven W. Ellingson is a 225-page, peer-reviewed open educational resource intended for electrical engineering students in the third year of a bachelor of science degree program. It is intended as a primary textbook for a one-semester first course in undergraduate engineering electromagnetics. The book employs the “transmission lines first” approach in which transmission lines are introduced using a lumped-element equivalent circuit model for a differential length of transmission line, leading to one-dimensional wave equations for voltage and current.

Escherichia coli MutL Loads DNA Helicase II onto DNA
No full textPrevious studies have shown that MutL physically interacts with UvrD (DNA helicase II) (Hall, M. C., Jordan, J. R., and Matson, S. W. (1998) EMBO J. 17, 1535-1541) and dramatically stimulates the unwinding reaction catalyzed by UvrD in the presence and absence of the other protein components of the methyl-directed mismatch repair pathway (Yamaguchi, M., Dao, V., and Modrich, P. (1998) J. Biol. Chem. 273, 9197-9201). The mechanism of this stimulation was investigated using DNA binding assays, single-turnover helicase assays, and unwinding assays involving long duplex DNA substrates. The results indicate that MutL binds DNA and loads UvrD onto the DNA substrate. The interaction between MutL and DNA and that between MutL and UvrD are both important for stimulation of UvrD-catalyzed unwinding. MutL does not clamp UvrD onto the substrate; and therefore, the processivity of unwinding is not increased in the presence of MutL. The implications of these results are discussed, and models are presented for the mechanism of MutL stimulation as well as for the role of MutL as a master coordinator in the methyl-directed mismatch repair pathway

Book Review: We Had to Get Out of That Place: A Memoir of Redemption and Betrayal in Vietnam
No full textAuthor: Steven Grzesik
Reviewed by Dr. Wylie W. Johnson, chaplain, US Army War College Class of 2010
Dr. Wylie W. Johnson reviews Vietnam War veteran Steven Grzesik’s memoir that, as Johnson explains, shows the effects of “the Army’s institutional policies” and how “[u]nit cohesiveness begins with senior leadership.” Grzesik’s personal experiences and the “isolation, abuse, and sacrifice of individual replacements” (which Johnson identifies as important themes in the book) provide a valuable perspective on “the imperative of caring for soldiers.”https://press.armywarcollege.edu/parameters_bookshelf/1070/thumbnail.jp
