Poema of Lieutenant Schmidt’s End: Pasternak’s Dialogue with Tsvetaeva through the Prism of Genre.

Boris Pasternak’s poemy are acutely self-conscious of their place in the epic tradition. Lieutenant Schmidt (LS) represents one attempt at exploring the parameters of the poema itself as the poet makes a “difficult” transition from “lyric thinking” to “the epic.” In this article I examine this transition against a contemporaneous example in the genre, Tsvetaeva’s Poema of the End (PE). In LS, structural elements of the poema are counterposed to those of PE. While PE amplifies the individual voice, LS muffles what is personal for the sake of the public voice. While PE is atemporal, LS is historical. While PE unfolds on symbolic planes, with elements of plot kept to a bare minimum (a single moment of separation), LS is a plot-driven account based on concrete, documentary material. Finally, while PE is an “overgrown lyric”—representing the “lyric thinking” that Pasternak hopes to transcend— LS is an exploration of the possibilities that a more traditional model of the poema can offer. Although in the present analysis I draw on several theories of poetic genres, this is by no means an exhaustive study of epic versus lyric forms of poetry. Instead, my analysis focuses on those structural and thematic features of the poema that the poets themselves perceived as central to their texts. Pasternak, for his part, develops the structure and thematics of his poema in ways that are inspired by PE, but also, as we will see, in more significant ways, contrast with it.

Utilization of Probabilistic Models in Short Read Assembly from Second-Generation Sequencing

With the advent of cheaper and faster DNA sequencing technologies, assembly methods have greatly changed. Instead of outputting reads that are thousands of base pairs long, new sequencers parallelize the task by producing read lengths between 35 and 400 base pairs. Reconstructing an organism’s genome from these millions of reads is a computationally expensive task. Our algorithm solves this problem by organizing and indexing the reads using n-grams, which are short, fixed-length DNA sequences of length n. These n-grams are used to efficiently locate putative read joins, thereby eliminating the need to perform an exhaustive search over all possible read pairs. Our goal was develop a novel n-gram method for the assembly of genomes from next-generation sequencers. Specifically, a probabilistic, iterative approach was utilized to determine the most likely reads to join through development of a new metric that models the probability of any two arbitrary reads being joined together. Tests were run using simulated short read data based on randomly created genomes ranging in lengths from 10,000 to 100,000 nucleotides with 16 to 20x coverage. We were able to successfully re-assemble entire genomes up to 100,000 nucleotides in length.

Corrosion Characteristics And Mechanical Properties Of Aluminum Coatings Applied By The Cold Spray Process

Aluminum coatings were applied to 2024-T3 and 7075-T6 aluminum alloys via the Cold Spray process. The coatings were applied to substrateswith various surface preparation and Cold Spray carrier gas combinations. Some samples were coated with an additional sealant with and without a chromate conversion layer. An exhaustive corrosion analysis was then performed which utilized a number of long termand accelerated tests in order to characterize the corrosion protection of the coatings.
