In a study of the prevalence of rectal infection with herpes simplex virus (HSV) in a group of homosexual men the magnified appearance of the rectal mucosa correlated with isolation of the virus. HSV was isolated from rectal material from five of 77 men with proctitis of unknown cause but from none of 44 control patients without proctitis; two of four men with HSV proctitis were asymptomatic. T...

A compact multicolor beam illuminator and a compact multicolor beam expander are presented. The illuminator performs the dual task of demultiplexing a narrow red-green-blue (RGB) input beam into three separate beams, each of a different color, and expanding them to yield three separate magnified plane waves. The beam expander expands a narrow RGB input beam into a single magnified RGB plane wav...

High-contrast imaging systems with a stellar halo suppression level of 10(-10) are required for direct detection of Earth-like extra-solar planets. We investigated a novel high-contrast imaging system with an unbalanced nulling interferometer (UNI) followed by phase and amplitude correction (PAC), which not only can reduce starlight but also can suppress the speckle level caused by wavefront ab...

We studied the affect infusing capability of multitasking (by task switching) in a computer based environment. Our central thesis is that multitasking places increased cognitive load and cognitive switching costs on individuals leading to affect infusion during cognitive processing. These effects become magnified and negatively valenced when individuals demonstrate lower self efficacy in the us...

We demonstrate quantitative noninterferometric x-ray phase-amplitude measurement. We present results from two experimental geometries. The first geometry uses x rays diverging from a point source to produce high-resolution holograms of submicrometer-sized objects. The measured phase of the projected image agrees with the geometrically determined phase to within +/-7%. The second geometry uses a...

The operational function of the trunk limbs (thoracic appendages), Daphnia, P3 and P4, is a long-term disputed definition between “solid walls”, sieving filters. Sieving unlikely process for routine particle collection, capture not simple mechanical by alone. Analysis promotion supported direct observational examination in-vivo cinematographic slow-motion film magnified solid photos tethered Da...

The medieval catapult weapon known as the trebuchet provides a useful physical analog for the impact of the many leverage effects that exist in a business firm and its performance. The trebuchet is explained, as are an extensive number of leverage effects for the business firm. The algebraic framework for determining the leverage effects in a business is presented and explained. The implication...
