Characterization of the 5' flanking region of rainbow trout ki-ras gene was begun with the cloning and sequencing of this region by the inverse PCR technique and dideoxynucleotide chain termination method. In total, a nucleotide sequence of 1080 bp upstream from the first coding ATG was sequenced. Although this region...
Multiple-input multiple-output (MIMO) antenna technology is promising
for high-speed wireless communications without increasing the transmission band-
width. Space time coding (STC) is a scheme that employs multiple antennas to
increase transmission rate or to improve transmission quality. STC is used widely
in mobile cellular networks, wireless local area networks (WLAN)...
Predictions of mechanical collisions between two bodies frequently cannot be completed by the impulse-momentum equation together with a complete description of the motion of the system at the initial contact. Additional account must be taken of the deformations and frictional interaction induced by the impulsive reaction force, where the bodies...
The structural architecture present in marine toxin azaspiracid - 20 stereocenters, 9 rings, 3 separated spirocenters - has attracted considerable synthetic attention. Our efforts toward the synthesis of azaspiracid have led to the completion of both C₁-C₂₆ northern and C₂₇-C₄₀ southern halves. Herein, the
synthesis of southern FGHI ring system...
RNAs play important roles in the central dogma of molecular biology, and are involved in multiple biology processes such as chromatin modification, transcriptional interference and translation initiation. The functions of RNAs, especially non-coding RNAs, are highly related to its secondary structures, therefore computational methods for RNA structure prediction are of...
Yutian (Cry to Heaven) is the third Chinese stage adaptation of Harriet Beecher Stowe’s novel Uncle Tom’s Cabin between 1907 and 2007. The first, Heinu yutian lu (Black Slave’s Cry to Heaven) by Zeng Xiaogu, was staged by Chinese students in Tokyo in 1907; the second, Heinu hen (Regret of...
To avoid unresponsiveness, a core part of mobile development is asynchronous programming. Android provides several async constructs that developers can use. However, developers can still use the inappropriate async constructs, which result in memory leaks, lost results, and wasted energy. Fortunately, refactoring tools can eliminate these problems by transforming async...
The discovery of new blue pigments is a field of great interest, as commercially available pigments present properties that make them undesirable such as poor sustainability, cost, and stability. By researching solid solutions with the melilite structure, we discovered a new solid solution Sr2Zn1-xNixGe2O7, with 0.1 ≤ x ≤ 0.6,...
We demonstrate a four-channel on-chip true-time-delay module based on a photonic crystal waveguide array. Using the photonic crystal taper to minimize the coupling loss, the delay lines with 1-3 mm long photonic crystal waveguides can operate up to a group index n(g) similar to ~23 without significant loss. The large...
