The outflows and 3D structure of NGC 6337, a planetary nebula with a close binary nucleus (2009)
García-Díaz, Ma. T., Clark, D. M., López, J. A., Steffen, W., Richer, M. G.
NGC 6337 is a member of the rare group of planetary nebulae where a close binary nucleus has been identified. The nebula's morphology and emission line profiles are both unusual, particularly the...

We use the previously-identified 15 infrared star-cluster counterparts to X-ray point sources in the interacting galaxies NGC 4038/4039 (the Antennae) to study the relationship between total cluster...

Infrared Counterparts to Chandra X-Ray Sources in the Antennae (2006)
Clark, D. M., Eikenberry, S. S., Brandl, B. R., Wilson, J. C., Carson, J. C., Henderson, C. P., ...
We use deep J and Ks images of the Antennae (NGC 4038/9) obtained with WIRC on the Palomar 200-inch telescope, together with the Chandra X-ray source list of Zezas et al. (2002a), to search for IR...
Deep Near-Infrared Imaging and Photometry of the Antennae Galaxies with WIRC (2005)
Brandl, B. R., Clark, D. M., Eikenberry, S. S., Wilson, J. C., Henderson, C. P., Barry, D. J., ...
We present deep near-infrared images of the Antennae galaxies, taken with the Palomar Wide-Field Infrared Camera WIRC. The images cover a 4.33' x 4.33' (24.7kpc x 24.7kpc) area around the galaxy...
The Antennae Ultraluminous X-Ray Source, X-37, Is A Background Quasar (2005)
Clark, D. M., Christopher, M. H., Eikenberry, S. S., Brandl, B. R., Wilson, J. C., Carson, J. C., ...
In this paper we report that a bright, X-ray source in the Antennae galaxies (NGC 4038/9), previously identified as an ultra-luminous X-ray source, is in fact a background quasar. We identify an...
Preliminary Evaluation of the Alaskan Long-Period Array, (2005)
Clark,D. M., Masse,R. P., Dunavant,J. E.
The object of this study was to determine the characteristics of signals and noise as recorded at the Alaska Long Period Array (ALPA), and to evaluate the performance of signal processing techniques...
PRELIMINARY BEAMFORMING STUDY OF THE TFO-37 ARRAY. (2005)
Beamforming of the TFO-37 array reduces the rms of the noise up to 14 db over an average single sensor, and the signal/noise improvement approaches 14 db also depending on the band pass filter used....
PRELIMINARY EVALUATION OF NORSAR. (2005)
A preliminary evaluation of NORSAR, using short-period data from one noise sample and two teleseismic events, was performed to determine: (1) the minimum inter-sensor spacing required to produce...
Blandford, R. R., Clark, D. M.
We present a method for predicting the noise reduction by simple beamforming of an array. The method gives an accurate estimate of the known capabilities of LASA, and is applied to the design of...
Clark,D. M., Sweetser,E. I., Der,Zoltan A.
Further analysis of the anomalous events in the eastern Himalaya region with an expanded set of stations shows that the M sub s values of these events are indeed low compared to m sub b. Other...
Investigation of P Travel Time-Curve. (1998)
By using a large number of LRSM stations and a number of earthquakes from all azimuths and the well controlled nuclear explosions, a study of the 'P' travel-time curve reveals it to be nearly a...

BEDSIDE ESTIMATION OF WHOLE BLOOD LACTATE (1978)
SOUTTER, W. P., SHARP, F., CLARK, D. M.
A new instrument for the measurement of lactate in biological fluids, the Lactate Analyzer 640, has been evaluated. The method of use recommended by the manufacturer for blood samples was found to be...
Luirink, J, Clark, D M, Ras, J, Verschoor, E J, Stegehuis, F, De Graaf, F K, ...
By oligonucleotide-directed mutagenesis, stop codon mutations were introduced at various sites in the pCloDF13-derived bacteriocin release protein (BRP) structural gene. The expression, lipid...
Definitive identification of human T cells in formalin fixed paraffin wax embedded tissue.
Francis, N D, Clark, D M, Boylston, A W
The use of a new monoclonal antibody, BF1, which reacts in routinely fixed tissues, directed against the beta chain of the T cell antigen receptor was assessed to determine its reactivity in a...

Synchronous adenocarcinoma and primary malignant lymphoma of the stomach.
Akosa, A. B., Clark, D. M., Desa, L.
A synchronous presentation of an adenocarcinoma and a primary low grade B cell lymphoma of the stomach is reported in a 79 year old man. Both diagnoses were made on endoscopic biopsies and...
