Richard Hell, 20th Annual ODU Literary Festival
Richard Hell musician, poet, and novelist is best known for his album with the Voidoids, “Blank Generation.” William Gibson has said, “Go Now is a vile, scabrous, unforgivable novel and deserving of the widest possible audience.” Hell is also the author of several books of poems including I Was a Spiral on the Floor (Soyo Publications, 1988), Across The Years, and Wanna Go Out, collaborative poems with Tom Verlain. His work has been widely anthologized in collections such as Out of this World (poems, Crown Publishers, 1992), and Jungles D’Ameriques (fiction, AAC Editions, Paris, 1993). Hell currently lives and writes in New York City

Continuous wave excitation two-photon fluorescence microscopy exemplified with the 647-nm ArKr laser line.
We report on efficient two-photon fluorescence imaging in beam scanning microscopy by exciting UV dyes at the 647-nm line of a continuous wave ArKr mixed gas laser. For a numerical aperture of 1.4 (oil), we used an illumination power of up to 210 mW at the sample. High-resolution images were obtained for DAPI-labelled cell nuclei within 4-60 s. Our method is a simple two-photon alternative to UV confocal imaging with the potential of becoming a very useful feature of laser scanning microscopy
Fluorescence lifetime three-dimensional microscopy with picosecond precision using a multifocal multiphoton microscope
The combination of pulsed-mode excitation multifocal multiphoton microscopy with a high-repetition, time-gated intensified CCD camera enables efficient three-dimensional (3D) fluorescence lifetime imaging. With a 200-ps gate opening at 76 MHz repetition rate, fluorescence decay can be traced in a sequence of images with varying delays between pulse and gate. Fluorophore lifetimes are measured with a precision of a few picoseconds. As an application we show that, upon two-photon excitation at 800 nm, certain pollen samples feature a multiexponential fluorescence relaxation. Our results indicate that efficient four-dimensional microscopy with hundreds of nanometer spatial and tens of picoseconds temporal resolution is within reach. (C) 1998 American Institute of Physics.

Multifocal multiphoton microscopy: A fast and efficient tool for 3‐D fluorescence imaging
Multifocal multiphoton microscopy (MMM) is an efficient and technically simple method for generating multiphoton fluorescence images. Featuring the high axial resolution of confocal and multiphoton scanning microscopes, MMM also achieves high speed in 3-D microscopy. In this paper, examples of fast-mode 3-D microscopy are given including imaging of fixed brain tissue as well as living PC12 cells. The imaging speed of MMM is solely determined by the fluorescence photon Bur, so that in practice, for brightly fluorescent specimens, a whole stack of about 50 images of 30-70 mu m diameter can be acquired within a few seconds. MMM represents a significant advance towards high speed nonlinear optical tomography of fluorescent specimens
STED nanoscopy with wavelengths at the emission maximum
Commonly, in stimulated emission depletion (STED) fluorescence nanoscopy, light of a wavelength located at the red tail of the emission spectrum of the dye is used to shrink the effective fluorophore excitation volume and thus to obtain images with sub diffraction resolution. Here, we demonstrate that continuous wave (CW) STED nanoscopy is feasible using STED wavelengths located at the emission maximum, where the cross section for stimulated emission is up to 10-fold larger than at the red tail. As a result, STED imaging becomes possible at equally lower STED beam power. Besides, fluorophores that have been considered inapplicable in certain wavelength constellations are thus becoming usable.Fil: Bordenave, Martín Diego.

The fire that reconciles : theological reflections on the doctrine of eternal punishment, with special consideration of annihilationism and traditionalism
This study enters into the dialog within Christian theology between annihilationism and traditionalism on the nature of eternal punishment. The positions and issues within the topic will be examined theologically and analyzed doctrinally.
In my first chapter I will summarize the views and arguments in the debate, establish operating definitions, address preliminary issues, and provide some historical context. I will establish a thesis agenda with dual aspects: negatively, to examine and critique annihilationism on theological grounds, and positively to offer arguments for a modified traditionalism.
Chapters two, three, and four primarily serve the negative purpose. Chapter two critically considers annihilationism on exegetical and hermeneutical issues, concluding that the view is inferior to traditionalism. Chapter three examines annihilationism for consistency with other areas of Christian theology, concluding that the view generates major theological problems in Christology. Chapter four considers both annihilationism and traditionalism regarding the disproportionality problem of hell, concluding that annihilationism and two types of traditionalism can resolve the problem but of these three only one sort of traditionalism can do so whilst also satisfying other important theological criteria. Regarding the negative aspect of the thesis, I conclude that the severe theological problems in annihilationism constitute sufficient reason to reject the view.
In chapter five I accomplish the positive aspect of this thesis, offering six criteria of success for any view of eternal punishment. I then provide detailed argumentation for a modified traditionalism called reconciliationism, concluding it best meets these criteria and is the most theologically and exegetically satisfying view on offer. In the concluding chapter I state this thesis’ contributions, suggest several areas for further research, and offer some implications for pastoral theology.
I finally conclude that annihilationism has seemingly insurmountable theological problems, but a modified traditionalism can succeed as a doctrine of hell

Two- and multiphoton detection as an imaging mode and means of increasing the resolution in far-field light microscopy: A study based on photon-optics
A photon‐optics interpretation of the image formation in a scanning single or two‐photon excitation fluorescence microscope is given. This interpretation predicts the possibility of two‐photon or multiphoton imaging modes based on simultaneous detection of two or more photons. We point out that by simultaneous detection of n photons stemming from the same point, the detection point‐spread‐function is raised to the nth power. In a two‐photon detection microscope, pairs of photons rather than single photons are taken as the signal. We discuss the fundamental requirements of two‐photon detection microscopy and the potential and limitations of this imaging mode. Two‐photon detection leads to a reduction of the spatial extent of the detection point spread function and therefore to an increase of resolution, but also to a reduction of the total signal. The theoretically predicted narrowing of the point spread function as well as the reduction of the detected signal is confirmed in an experiment simulating the two‐photon detection situation. In addition, we show a precise recording of the point‐spread function of a 1.4 numerical aperture oil immersion lens at a wave length of 750 nm and the corresponding point‐spread‐function of a two‐photon detection imaging mode
Even More Happiness in Hell
Published in 1892, St. George Jackson Mivart’s remarkably original article ‘Happiness in Hell’ was placed on the Index Librorum Prohibitorum almost immediately. In his article, Mivart proposed a solution to the problem of hell whose core contention is that hell is horrible only from a heavenly point of view. From a this-worldly point of view, by contrast, hell is a place of breathtaking felicity. In my opinion, this proposal has some striking merits, at least if it is updated and developed in certain respects. The purpose of this article is to reconstruct it, to reassess it, and to put it back on the table of eschatological ideas
