[1] We have observed intensity scintillation (IPS) of the radio source 0854 + 201 at 8 GHz on August 2, 2000 during the passage of a coronal mass ejection (CME) across the line of sight. The source was at a distance of 10 R over the north solar pole. Simultaneous observations with the LASCO C3 instrument allow us to model the mean density Ne and the microscale density fluctuations dNewithin the...

Details are presented of a method to resolve close tracks in cathode strip chambers based on the t to the induced charge distribution. The analysis of muon beam test data demonstrated a double track resolution of about 2 mm for a readout pitch of 5 mm. The degradation of the position resolution in presence of a close track is limited to 10% of the readout pitch.

A new type of visual display for presentation of a visual stimulus with high quality was assessed. The characteristics of an organic light-emitting diode (OLED) display (Sony PVM-2541, 24.5 in.; Sony Corporation, Tokyo, Japan) were measured in detail from the viewpoint of its applicability to visual psychophysics. We found the new display to be superior to other display types in terms of spatia...

BACKGROUND There are limited data on the prognostic implications of brain natriuretic peptide (BNP) assessment in patients with mildly symptomatic heart failure (HF) who receive cardiac resynchronization therapy with a defibrillator (CRT-D). METHODS AND RESULTS The effect of elevated baseline and 1-year BNP levels (dichotomized at the upper tertile BNP of 120 pg/mL) on the risk of HF or death...

In this work, textured, well-faceted ZnO materials grown on planar Si(100), planar Si(111), and textured Si(100) substrates by low-pressure chemical vapor deposition (LPCVD) were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), and cathode luminescence (CL) measurements. The results show that ZnO grown on planar Si(100), planar Si(111), and...

Current research highlights the use of aquatic macrophyte Equisetum diffusum (Himalayan horsetail) for lead detoxification. This plant species can grow in waste cathode ray tube (CRT) powder and absorbs its Pb. X-ray fluorescence spectroscopy (XRF) analysis of plant ash shows that 68 mg/kg lead concentration in the untreated plant was improved to 7600 mg/kg in CRT powder after 90 days. The role...

This paper is about a phenomenon, and a mechanism to explain the phenomenon. The observation is that the dynamic transfer properties of the cat retina are altered when the contrast of the visual stimulus is changed. The peculiar dependence of the “contrast effect” on the spatial and temporal properties of the visual stimulus led us to the conclusion that the contrast effect is caused by a separ...
