The Connection Machine CM-5 supports both SIMD and MIMD programming modes. The SIMD mode is simulated over the MIMD mode. This simulation is likely to lead to a loss of performance in SIMD programs. This paper describes the design and implementation of benchmarks which were used to bring out the diierence in speed between the two programming modes with CM Fortran and message-passing Fortran. Tw...

A detector for high-resolution momentum measurements of neutrons in the energy range 0.2-1.0 GeV is being developed for the RB experiment at FAIR. Two solutions are currently being studied: A pure scintillator concept and an approach based on a sequence of converter material (iron) to produce secondary charged particles, and Multigap Resistive Plate Chambers (MRPC’s) to detect these particles. ...

We present new high-resolution observations of Sagittarius A* at wavelengths of 17.4 to 23.8 cm with the Very Large Array in A configuration with the Pie Town Very Long Baseline Array antenna. We use the measured sizes to calibrate the interstellar scattering law and find that the major axis size of the scattering law is smaller by ∼ 6% than previous estimates. Using the new scattering law, we ...

Recently, many details of the interplay between tumor cells and tumor-associated stromal elements leading to the progression of malignant disease were elucidated. In contrast, little is known about the role of uninvolved stromal tissue in the remote surrounding of the malignant tumor. Therefore, we performed a computer-aided morphometric study of rectal mucosa in samples taken 10 cm and 20 cm a...

Diagnosing UTIs is done through a combination of clinical history, examination, and laboratory tests. Infants and the elderly may present with no symptoms at all. Other patients might complain of fever, chills, anorexia, nausea, vomiting, diarrhea, pain in the abdomen or back, dysuria, hematuria, incontinence, decreased urine output or the inability to urinate, and/or altered mental status/conf...

The use of orthotic heel lifts is proposed in many cases of Achilles tendon disorders as a first-line or conservative treatment. The use of heeled shoes induces a plantar flexion of the ankle joint with a consequent decrease in the tension forces acting onto the triceps surae. The question to address is how high must the heel be? Gait cycle using 1 cm- and 2 cm-high heel lifts was examined. Eac...

As a generalization of the 2D Fourier transform (2D FT) and 2D fractional Fourier transform, the 2D nonseparable linear canonical transform (2D NsLCT) is useful in optics and signal and image processing. To reduce the digital implementation complexity of the 2D NsLCT, some previous works decomposed the 2D NsLCT into several low-complexity operations, including 2D FT, 2D chirp multiplication (2D...

Introduction The Department of Defense conducts syndromic surveillance of health encounter visits of Military Health System (MHS) beneficiaries. Providers within the MHS assign up to 10 diagnosis codes to each health encounter visit. The diagnosis codes are grouped into syndrome and sub-syndrome categories. On October 1, 2015, the Health and Human Services-mandated transition from ICD9-CM to IC...

We describe the implementation of a fluid dynamical benchmark on the 2048 vector node CM-200 parallel computer and on the 1024-node CM-5 computer. The benchmark, the Shallow Water Equations, is frequently used as a model for both oceanographic and atmospheric circulation. We describe the steps involved in implementing the algorithm on the two Thinking Machines Corporation computers and we provi...

ABOUT THE COVER " I t isn't up to the painter to define the symbols, " said Pablo Picasso when asked to explain his celebrated mural, Guernica. " ….The public who look at the picture must interpret the symbols as they understand them. " Picasso himself did not know what the work would turn out to be when he was commissioned to paint the center-piece for the Spanish Pavilion of the 1937 World's ...
