Matrix variate and tensor variate Laplace distributions [PDF]
In this article, we define a matrix variate asymmetric Laplace distribution. We prove some properties of the matrix variate asymmetric Laplace distribution. We prove the relationship between the matrix variate asymmetric Laplace distribution and other distributions. We define a matrix variate generalized asymmetric Laplace distribution.

Asymmetric organocatalysis involving double activation
Asymmetric organocatalysis contributed tremendously to the field of organic synthesis since year 2000. Considering the diversity of organocatalysts and their activation modes, chemists developed the double activation strategy, in which two distinct ...

A note on asymmetric hypergraphs [PDF]
A $k$-graph $\mathcal{G}$ is asymmetric if there does not exist an automorphism on $\mathcal{G}$ other than the identity, and $\mathcal{G}$ is called minimal asymmetric if it is asymmetric but every non-trivial induced sub-hypergraph of $\mathcal{G}$ is non-asymmetric. Extending a result of Jiang and Ne\v{s}et\v{r}il, we show that for every $k$-graph, $

Cooperative effects between arginine and glutamic acid in the amino acid catalyzed aldol reaction [PDF]
Catalysis of the aldol reaction between cyclohexanone and 4-nitrobenzaldehyde by mixtures of L-Arg and of L-Glu in wet DMSO takes place with higher enantioselectivity (up to a seven-fold enhancement in the anti- aldol for the 1:1 mixture) than that ...

Nonlinear SVD with Asymmetric Kernels: feature learning and asymmetric Nyström method [PDF]
Asymmetric data naturally exist in real life, such as directed graphs. Different from the common kernel methods requiring Mercer kernels, this paper tackles the asymmetric kernel-based learning problem. We describe a nonlinear extension of the matrix Singular Value Decomposition through asymmetric kernels, namely KSVD. First, we construct two nonlinear

Cluster Preface: Non-Covalent Interactions in Asymmetric Catalysis [PDF]
The successful harnessing of non-covalent interactions to activate functional groups and control selectivity in chemical reactions is a relatively recent phenomenon in synthetic chemistry, but one that has delivered ground-breaking results, particularly ...
