EET in reconstituted Lhca4, a peripheral light-harvesting complex from Photosystem I of Arabidopsis thaliana, containing 10 chlorophylls and 2 carotenoids, was studied at room temperature by femtosecond transient absorption spectroscopy. Two spectral forms of Lut were observed in the sites L1 and L2, characterized by significantly different interactions with nearby chlorophyll a molecules. A fa...

This paper provide the principles of Modified Distributed Arithmetic, and introduce it into the FIR filters design, and then presents a 31-order FIR low-pass filter using Modified Distributed Arithmetic, which save considerable MAC blocks to decrease the circuit scale, meanwhile, divided LUT method is used to decrease the required memory units and pipeline structure is also used to increase the...

OBJECTIVE Report the relationship of composition with age and sex of the patients. MATERIAL AND METHOD A series of 426 urinary stones, 33 from the lower (LUT) and 393 from the upper urinary tract (UUT) of adults, were analyzed for their chemical composition using infrared spectroscopy. The majority of LUT stones were from males (n = 26) and in the age group beyond 60 years (n = 20). RESULTS...

Gain based predistorter (PD) is a highly effective and simple digital baseband predistorter which compensates for the nonlinear distortion of PAs. Lookup table (LUT) is the core of the gain based PD. This paper presents a discrete Newton’s method based adaptive technique to modify LUT. We simplify and convert the hardship of adaptive updating LUT to the roots finding problem for a system of two...

This paper presents a novel discrete particle swarm optimization (PSO) for frequency response masking (FRM) finite impulse response (FIR) digital filters over the canonical signed-digit (CSD) multiplier coefficient space. A look-up table (LUT) scheme is employed to ensure that the PSO automatically searches through permissible CSD multiplier coefficient values in the course of optimization with...

It makes no doubt that the development of innovative products benefits from being considered under the perspective of networks and communities. Lead User’s theory (LUT) focused mainly on the process by which user innovation may be transformed into commercial product. However, when LUT methodology was proven successful for products such as scientific instrument, sports equipment or even medical ...

Field Programmable Gate Array (FPGA) attributes of logic configurability, bitstream storage, and dynamic signal routing can be realized by leveraging the complementary benefits of emerging devices with Complementary Metal Oxide Semiconductor (CMOS)-based devices. In this paper, a novel Carbon/Magnet Lookup Table (CM-LUT) is developed and evaluated by trading off a range of mixed heterogeneous t...

Unexpected trails have been seen subsequent to relative bright sources in astronomical images taken with the CCD camera of the Lunar-based Ultraviolet Telescope (LUT) since its first light on the Moon’s surface. The trails can only be found in the serial-direction of CCD readout, differing themselves from image trails of radiation-damaged spaceborne CCDs, which usually appear in the parallel-re...

| Rapid system prototyping is one of the main applications for eld-programmable gate arrays (FPGAs). At the stage of rapid system prototyping, design speci cations can often be changed since they cannot always be determined completely. In this paper, layout design change is focused on and a layout recon guration algorithm is proposed for FPGAs. In layout recon guration, the main problem is to a...
