Ultra-low Amplitude Cepheids in the Large Magellanic Cloud
The MACHO variables of LMC Field 77 that lie in the vicinity of the Cepheid instability strip are reexamined. Among the 144 variables that we identify as Cepheids we find 14 that have Fourier amplitudes < 0.05 mag in the MACHO red band, of which 7 have an amplitude < 0.006mag : we dub the latter group of stars ultra-low amplitude (ULA) Cepheids. The variability of these objects is verified by a...
متن کاملLow amplitude QRS.
Scenario: This 12-lead ECG reading was obtained from a 76-year-old African American woman who presented to the emergency department with shortness of breath, fatigue, and a cough for the past month. Prior medical history includes chronic obstructive pulmonary disease, hypertension, and cigarette smoking for more than 40 years. ECG PUZZLER A regular feature of the American Journal of Critical Ca...
متن کاملAmplitude-dependent Ultrasound Attenuation Due to Inclined Dislocations
Amplitude dependence of the ultrasound attenuation and change of the elastic modulus due to the dislocations with a certain number of the geometrical kinks at zero temperature is investigated by the numerical simulation of dislocation motion. A decrease of attenuation before the amplitude of stress in a slip plane achieves the Peierls stress value is found. 1. In spite of a long period elapsed ...
متن کاملAmplitude and time measurement ASIC with analog derandomization
A versatile 32-channel ASIC has been developed for accurate processing of high-rate pulse signals from highly segmented detectors. In contrast to conventional approaches, this circuit affords a dramatic reduction in data volume through the use of analog techniques (precision peak detectors and time-to-amplitude converters) together with fast arbitration and sequencing logic to concentrate the d...
