Exploration of new ferroic (ferroelectric, ferromagnetic or ferroelastic) materials continues to be a central theme in condensed matter physics and to drive advances in key areas of technology. Here, using thin-film composition spreads, we have mapped the functional phase diagram of the Ni-Mn-Ga system whose Heusler composition Ni(2)MnGa is a well known(More)
For several years, magnetic-based current imaging has been used to localize current leakages and shorts by imaging currents in integrated circuits and packages. Recent advances have enabled this technology to be extended to localizing high resistance defects in packages to within 30 /spl mu/m, an order of magnitude better than time-domain reflectometry.(More)
The use of integral field spectroscopy is since recently allowing to measure the emission line fluxes of an increasingly large number of star-forming galaxies, both locally and at high redshift. Many studies have used these fluxes to derive the gas-phase metallicity of the galaxies by applying the so-called strong-line methods. However, the metallicity(More)
Magnetic Field Imaging (MFI) is a widely used technique in the Semiconductor industry for non-destructive Electrical Fault Isolation (EFI) for shorts, leakages and opens. When the devices shrink and the mobile electronics industry has a more strict criteria for speed with low power consumption, making High Resistance Opens (HRO) failures more important to(More)
Magnetic Current Imaging (MCI), a sub technique of Magnetic Field Imaging (MFI), has been used for more than a decade to localize shorts at the package as well as die and wafer level in a non-destructive way. One particular hard category of shorts to localize is a short between power and ground; the so called power shorts. We show in this paper that MCI can(More)
Magnetic Current Imaging (MCI) has been used for more than a decade to localize shorts and leakages in packages non-destructively. Now that packages are becoming more complex with multiple dies inside the same package, MCI is showing its effectiveness in localizing these complicated shorts non-destructively when the Failure Analysis (FA) engineer does not(More)
The eggs of Anopheles (Anopheles) apicimacula Dyar and Knab are described from scanning electron micrographs. The eggs are boat-shaped, with frills that extend ventrally along the length of the egg and surround the deck region. The ornamentation on the dorsal and lateral surfaces is formed by groups of smooth, round tubercles. The ventral surface is covered(More)
Scanning electron and light microscopic observations showed that egg hatching in Anopheles albimanus Wiedemann is aided by a chisel-shaped spine. This hatching tooth is surrounded by a thin flexible membrane fixed to a groove in the head of the larvae. Increased intracranial pressure may force the spine against the egg shell until a fissure is produced.(More)
