Asymmetric amplification during self-replication is a key feature that is used to explain the origin of homochirality. Asymmetric autocatalysis of pyrimidyl alkanol in the asymmetric addition of diisopropylzinc to pyrimidine-5-carbaldehyde is a unique example of this phenomenon. Crystallization of zinc alkoxides of this 5-pyrimidyl alkanol and single-crystal X-ray diffraction analysis of the al...

An asymmetric ratchet structure within microchannels is demonstrated by directionally guided light transmission for controlled liquid flow. A direct and facile method is presented to realize programmed asymmetric structures, which control the fluid direction and speed.

The performance and reliability of NMOSFET asymmetric lightly doped drain (LDD) devices (with no LDD on the source side) are compared with those of conventional LDD devices. At a fixed Vdd; asymmetric LDD devices exhibit higher Idsat and shorter hot-carrier lifetime. To maintain the same hot-carrier lifetime, asymmetric LDD devices must operate at lower Vdd while higher Idsat is retained. For t...

empirical studies show that there is stronger dependency between large losses than large profit in financial market, which undermine the performance of using symmetric distribution for modeling these asymmetric. that is why the assuming normal joint distribution of returns is not suitable because of considering the linier dependence, and can be lead to inappropriate estimate of var. copula theo...

The ®rst of the title compounds, C31H27NO4S, (V), crystallizes in the monoclinic space group P21/c with two independent molecules in the asymmetric unit, while the second, C23H27Cl2NS, (IX), crystallizes in the orthorhombic space group Pbca with one molecule in the asymmetric unit. In both crystal structures, the 1,3-thiazolidine ring adopts a half-chair conformation. The crystal structures are...

Charge sensing in quantum-dot structures is studied by an exactly solvable reduced model and numerical density-matrix renormalization-group methods. Charge sensing is characterized by repeated cycling of the occupation of current-carrying states due to the capacitive coupling to trap states. In agreement with recent experiments, it results in characteristic asymmetric Coulomb-blockade peaks as ...

In this study, we examine the predictions for processing of a syntactically articulated theory of the distinction among different interpretations of clausal 'and'. Bjorkman (2010) claims that symmetric 'and' interpretations involve coordination of CPs; these are logical interpretations. Asymmetric interpretations of 'and' involve conjunction of TPs; these are temporal and causal. If the process...

In this paper, we rigorously prove the existence and stability of K-peaked asymmetric patterns for the Gierer-Meinhardt system in a two dimensional domain which are far from spatial homogeneity. We show that given any positive integers k1, k2 ≥ 1 with k1 + k2 = K, there are asymmetric patterns with k1 large peaks and k2 small peaks. Most of these asymmetric patterns are shown to be unstable. Ho...
