A 100 A, 100 kHz Transconductance Amplifier
A high-current, wide-band transconductance amplifier is described that provides an unprecedented level of output current at high frequencies with exceptional stability. It is capable of converting a signal voltage applied to its input into a groundreferenced output rms current up to 100 A over a frequency range from dc to 100 kHz with a useable frequency extending to 1 MHz. The amplifier has a ...
متن کاملObservation of large wave vector interface spin waves: Ni(100)/fcc Co(100) and Cu(100)/Co(100)
Using electron energy loss spectroscopy, we have probed the spin waves of fcc(100) cobalt after capping with 1–3 atom layers of pseudomorphic nickel or up to 12 atom layers of copper. The intensity decay of the spin wave signal is quantitatively described by the mean-free path of the incident and the scattered electron within the capping layer. The observed spin waves are therefore localized at...
متن کاملگزارش 100 مورد لاپارسکوپی
100 patients (93 females and 7 males) in ages ranging between 23 and 65 years were subjected to laparoscopic cholecystectomy for biliary colic (92 pts), acute cholecystitis (7 pts) or asymptomatic gallstones (1 pt). None had a history of icterus and in every case choledocholithiasis was excluded by means of serum alkaline phosphatase assessment and sonography (In addition to ERCP in 3 pts). 3 o...
متن کاملInteraction of atomic hydrogen with monometallic Au(100), Cu(100), Pt(100) surfaces and surface of bimetallic Au@Cu(100), Au@Pt(100) overlayer systems: The role of magnetism
The spin-polarized calculations in generalized gradient approximation density–functional theory (GGA–DFT) have been used to show how the existence of second metals can modify the atomic hydrogen adsorption on Au (100), Cu (100), and Pt (100) surfaces. The computed adsorption energies for the atomic hydrogen adsorbed at the surface coverage of 0.125 ML (monolayer) for the monometallic Au (100), ...
متن کاملS S 100 Calcium - Binding Protein ▶ S 100 Proteins S 100 Proteins
S100 proteins were first discovered in 1965 by Moore as a major protein fraction (0.6% of total soluble protein) isolated from bovine brain (Moore 1965). The protein was given the name S100 due to its high solubility in saturated ammonium sulfate. Later experiments showed the S100 protein fraction constituted two different dimeric species comprised of two b protomers (S100B) or an a, b heterodi...
