Wire sweep characterization of multi-tier palladium-copper (Pd-Cu) wire bonding on LQFP package using low alpha green mold compound Controlling wire sweep is critical in transfer molding process as excessive results in shorting of wires, which in turn cause electrical failure. Therefore... SSS Ali...

because low-energy alpha particles can now flip a memory bit or change the timing of a logic circuit. One of the main sources of alpha particle radiation is the solder paste used to connect components in the package, which contains alpha radioactive elements. ...
Therefore, this compound was used in subsequent experiments. 3.2. Fucan B inhibits capillary-like tube formation of ECs on Matrigel We evaluated the effect of fucan B using a capillary-like tube formation assay. ECs in reconstituted basement membrane were able to migrate, form intercellular ...
4c). To see whether these effects were specific to amyloid aggregation of KRT8, we also assessed the aggregation of the amyloid proteins alpha-synuclein and tau in the presence of ethanol. Ethanol had a mild effect on the aggregation of alpha-synuclein (Fig. 4d) and no effect on tau (Fig...
Mass spectrometry-based spectral count has been a common choice of label-free proteome quantification due to the simplicity for the sample preparation and data generation. The discriminatory nature of spectral count in the MS data-dependent acquisition, however, inherently introduces the spectral count ...

formulations were tested in an in vivo pharmacokinetic study in rats with the aim of characterizing the bioavailability of spironolactone on the basis of its metabolites canrenone and 7-alpha-thiomethylspirolactone. In addition, a dose escalation study was carried out using nonmicronized spironolactone...
