摘要:
The invention provides a fast-cured sol material, which is produced by hydrolysis and condensation of the following starting materials: 2-60 parts by weight of a silicon alkoxide; 20-98 parts by weight of an alcohol; 0.5-50 parts by weight of an aqueous media; 0.0001-10 parts by weight of a base; 0.001-30 parts by weight of at least one additive; and optionally 0.0001-10 parts by weight of an acid. A coating of the sol material according to the invention can be directly cured (without aging) to obtain a microporous dielectric film without shrinkage or cracks.

摘要:
Prostasin protein has been found to be a useful marker for determination of the invasiveness of and as a means to treat human carcinomas. Using RT-PCR and western blot analyses, prostasin protein and mRNA expression were found in normal human prostate epithelial cells and the human prostate cancer cell line LNCaP, but not in the highly invasive human prostate cancer cell lines DU-145 and PC-3. Imunohistochemistry studies of human prostate cancer specimens revealed a down-regulation of prostasin in high-grade tumors. Using RT-PCR and western blot analyses, prostasin protein and mRNA expression were found in a non-invasive human breast cancer cell line, MCF-7, while invasive human breast cancer cell lines MDA-MB-231 and MDA-MB-435s were found not to express either the prostasin protein or the mRNA. A non-invasive human breast cancer cell line, MDA-MB-453, was shown to express prostasin mRNA but not prostasin protein. Transfection of DU-145 and PC-3 cells with a full-length human prostasin cDNA restored prostasin expression and reduced the in vitro invasiveness by 68% and 42%, respectively. Transfection of MDA-MB-231 and MDA-MB-435s cells with a full-length human prostasin cDNA restored prostasin expression and reduced the in vitro invasiveness by 50% for either cell line.

摘要:
A system and a method for calibrating an ambient light sensor (ALS) are disclosed. The ALS, an adjustable resistor and a switch are located on a first surface of a printed circuit board (PCB), and the adjustable resistor and the switch are connected in series between an adjustable probe of the ALS and the ground. A resistor is connected between two pads located on a second surface of the PCB via two probes touching the pads. A controller connected to the PCB reads a light sensitivity of the ALS and calculates a calculated resistance value of the adjustable resistor by a formula “detected light sensitivity/resistance value of the resistor=objective light sensitivity/resistance value of the adjustable resistor”, wherein the objective light sensitivity and the resistance value of the resistor are given.
