Abstract In 2018, Mexican poet Alí Calderón interviewed Charles Bernstein for his influential web magazine Círculo de poesía. The interview is published here in English for the first time. Bernstein addresses the poetics of “hybridity” and the possibilities for poetic disruption. The discussion ends with Bernstein's then new poem, written for John Ashbery on the day he died.

This book shows how the work of a major post-war American poet has been centrally concerned with questions of national identity and intercultural poetic exchange, by reading crucial episodes in John Ashbery’s oeuvre in the context of an ‘other tradition’ of twentieth-century English poets he himself has defined. This line runs from the editor of Ashbery’s recent Collected Poems, Mark Ford, through Lee Harwood in the late 1960s, F. T. Prince in the 1950s, to ‘chronologically the first and therefore most important influence’ on his own work, W. H. Auden. Through detailed close readings of the poetry of Ashbery and these English poets, original interviews, and extensive archival research, a new account of Ashbery’s ‘minor’ aesthetic and a significant re-mapping of postwar English poetry are presented. The biographical slant of the book is highly significant, as it reads these writers’ poetry and correspondence together for the first time, suggesting how major poetic innovations arose from specific social contexts, from the particulars of relations between poets, and also from a broader climate of transatlantic exchange as registered by each poet. The result is that both Ashbery himself, and the landscape of post-war English poetry, are viewed in a significantly new light.

Abstract The essay explores the work of Charles Bernstein in light of constant renewal. John Ashbery, as one of the brightest representatives of the New York School, and Charles Bernstein, as a representative of the language (L = A = N = G = U = A = G = E), have similar attitudes toward language. They have much in common in terms of poetics: in the rejection of loud phrases, prophetic statements, emotions, confessionalism, and certain self-centeredness. Poetry is a private matter for both. Both have poetics built on the “oddness that stays odd,” as Bernstein himself put it, paraphrasing Pound's “news that stays news.” Both are aimed at renovating the language, and the verses of both are built on fragmentation, collage, moving from one statement to another without preparation. However, in Ashbery, whose poems are surreal, these transitions are smoother, based on an apparent connection, what Bernstein calls “hypotaxis” or “associative parataxis.” In contrast, Bernstein's poetry is built on parataxis; it is “bumpy,” in the poet's own words.

First Time

Although the presence of annulate lamellae was noted in many cell types, including the rat spermatogenic cells, this structure was never reported in the Sertoli cells of any rodent species. The present report is based on a part of our project on the effect of torsion of the spermatic cord to the contralateral testis. This paper describes for the first time, the fine structural details of the annulate lamellae in the Sertoli cells of damaged testis from guinea pigs.One side of the spermatic cord of each of six Hartly strain adult guinea pigs was surgically twisted (540°) under pentobarbital anesthesia (1). Four months after induction of torsion, animals were sacrificed, testes were excised and processed for the light and electron microscopic investigations. In the damaged testis, the majority of seminiferous tubule contained a layer of Sertoli cells with occasional spermatogonia (Fig. 1). Nuclei of these Sertoli cells were highly pleomorphic and contained small chromatinic clumps adjacent to the inner aspect of the nuclear envelope (Fig. 2).

A new Zeiss TEM with an imaging Omega filter is a fully digitized, side-entry, 120 kV TEM/STEM instrument for materials science. The machine possesses an Omega magnetic imaging energy filter (see Fig. 1) placed between the third and fourth projector lens. Lanio designed the filter and a prototype was built at the Fritz-Haber-Institut in Berlin, Germany. The imaging magnetic filter allows energy-filtered images or diffraction patterns to be recorded without scanning using efficient area detection. The energy dispersion at the exit slit (Fig. 1) results in ∼ 1.5 μm/eV which allows imaging with energy windows of ≤ 10 eV. The smallest probe size of the microscope is 1.6 nm and the Koehler illumination system is used for the first time in a TEM. Serial recording of EELS spectra with a resolution < 1 eV is possible. The digital control allows X,Y,Z coordinates and tilt settings to be stored and later recalled.

Microstructural Studies

Microstructural studies by transmission electron microscopy (TEM) of diamond films grown by chemical vapor deposition (CVD) usually involve tedious specimen preparation. This process has been avoided with a technique that is described in this paper. For the first time, thick as-grown diamond films have been examined directly in a conventional TEM without thinning. With this technique, the important microstructures near the growth surface have been characterized. An as-grown diamond film was fractured on a plane containing the growth direction. It took about 5 min to prepare a sample. For TEM examination, the film was tilted about 30-45° (see Fig. 1). Microstructures of the diamond grains on the top edge of the growth face can be characterized directly by transmitted electron bright-field (BF) and dark-field (DF) images and diffraction patterns.

Transmission and analytical electron microscopic studies of scale microstructures and microscopic marker experiments have been carried out in order to determine the transport mechanism in the oxidation of Ni-Al alloy. According to the classical theory, the oxidation of nickel takes place by transport of Ni cations across the scale forming new oxide at the scale/gas interface. Any markers deposited on the Ni surface are expected to remain at the scale/metal interface after oxidation. This investigation using TEM transverse section techniques and deposited microscopic markers shows a different result,which indicates that a considerable amount of oxygen was transported inward. This is the first time that such fine-scale markers have been coupled with high resolution characterization instruments such as TEM/STEM to provide detailed information about evolution of oxide scale microstructure.

First Time

The electron holes confined to the CuO2-plane are the charge carriers in high-temperature superconductors, and thus, the distribution of charge plays a key role in determining their superconducting properties. While it has been known for a long time that in principle, electron diffraction at low angles is very sensitive to charge transfer, we, for the first time, show that under a proper TEM imaging condition, it is possible to directly image charge in crystals with a large unit cell. We apply this new way of studying charge distribution to the technologically important Bi2Sr2Ca1Cu2O8+δ superconductors.Charged particles interact with the electrostatic potential, and thus, for small scattering angles, the incident particle sees a nuclei that is screened by the electron cloud. Hence, the scattering amplitude mainly is determined by the net charge of the ion. Comparing with the high Z neutral Bi atom, we note that the scattering amplitude of the hole or an electron is larger at small scattering angles. This is in stark contrast to the displacements which contribute negligibly to the electron diffraction pattern at small angles because of the short g-vectors.

Beam Damage

Over the past decade low voltage scanning electron microscopy (LVSEM) of polymers has evolved from an interesting curiosity to a powerful analytical technique. This development has been driven by improved instrumentation and in particular, reliable field emission gun (FEG) SEMs. The usefulness of LVSEM has also grown because of an improved theoretical and experimental understanding of sample-beam interactions and by advances in sample preparation and operating techniques. This paper will review progress in polymer LVSEM and present recent results and developments in the field.In the early 1980s a new generation of SEMs produced beam currents that were sufficient to allow imaging at low voltages from 5keV to 0.5 keV. Thus, for the first time, it became possible to routinely image uncoated polymers at voltages below their negative charging threshold, the "second crossover", E2 (Fig. 1). LVSEM also improved contrast and reduced beam damage in sputter metal coated polymers. Unfortunately, resolution was limited to a few tenths of a micron due to the low brightness and chromatic aberration of thermal electron emission sources.
