A method and an illumination system for simulating a CIE standard illuminant with a multi-channel LED are disclosed. The method includes adjusting a brightness of the main light source control channel, the wavelength complementary control channel, the color temperature adjustment control channel to make a mixed chromaticity coordinate meet a chromaticity coordinate of the CIE standard illuminant to be simulated according to chromaticity coordinates. The LED control channels are reduced through group optimization, and a technology which is discarded by multi-channel LED such as a filter is used, a control of a light source substantially reducing number of control channels and enabling a multi-channel LED to simulate a standard illuminant is formed, such that a single chromaticity control rather than a chromaticity control which must be transformed by a spectral conversion is achieved.

The present invention provides a method of rapid directed DNA evolution based on single-stranded combinatorial DNA mutant library. The single- and double-stranded mutant library are constructed either separately or simultaneously using editing primers that contain mutated nucleotides and are targeted to different regions of the parent DNA sequence. The mutant library is then inserted into expression vectors and mutants with desired property are obtained by high throughput screening. Evolution of promoters, enzymes and metabolic pathways were successfully achieved using this method and mutants with excellent properties were obtained. The method of the present invention is simple, rapid, and efficient. It can be used for directed evolution of regulatory sequence such as promoters and ribosome binding sites, and is especially suitable for introducing diverse mutations into protein encoding genes, leading to rapid directed evolution of gene of interest.

Methods and compositions comprising chemical compounds that modulate the silencing of a polynucleotide of interest in a cell are provided. Such chemical compounds when used in combination with an appropriate silencing element can be used to modulate (increase or decrease) the level of the polynucleotide targeted by the silencing element. Methods of using such compositions both in therapies involving RNAi-mediated suppression of gene expression, as well as, in vitro methods that allow for the targeted modulation of expression of a polynucleotide of interest are provided. Pharmaceutical or cosmetic compositions comprising such compounds and silencing elements also are disclosed. Methods for screening a compound of interest for the ability to modulate the activity of a heterologous silencing element also are provided.

The present invention provides a lithographic process for producing high aspect ratio parts from an epoxy-type negative photoresist comprising the steps of: (i) irradiating a prebaked masked epoxy-type negative photoresist on a substrate with light at a total energy density of from 18,000 to 35,000 mJ/cm2, (ii) post-baking the exposed photoresist at elevated temperature, and (iii) developing the exposed photoresist in a solvent, wherein no more than 15% of the energy density is contributed by light having a wavelength of 400 nm or less. The invention also discloses a reciprocating microengine (10) comprising a cylinder (14), piston (12) and crankshaft made by the process.
