We introduce the 2D counterpart of layered black phosphorus, which we call phosphorene,
as an unexplored p-type semiconducting material. Same as graphene and MoS 2 , single-…

We propose a semiparametric approach called the nonparanormal SKEPTIC for efficiently
and robustly estimating high-dimensional undirected graphical models. To achieve modeling …

Big Data bring new opportunities to modern society and challenges to data scientists. On
the one hand, Big Data hold great promises for discovering subtle population patterns and …

We present a new class of methods for high dimensional non-parametric regression and
classification called sparse additive models. Our methods combine ideas from sparse linear …

Autism spectrum disorders (ASD) are believed to have genetic and environmental origins,
yet in only a modest fraction of individuals can specific causes be identified 1 , 2 . To identify …

RE/TiO 2 photocatalysts were prepared by the sol–gel method using rare earth (RE=La 3+ ,
Ce 3+ , Er 3+ , Pr 3+ , Gd 3+ , Nd 3+ , Sm 3+ ) metal salts and tetra-n-butyl titanate as …

Since December 2019, novel coronavirus infected pneumonia emerged in Wuhan city and
rapidly spread throughout China. In severe novel coronavirus pneumonia cases, the number …

For more than 100 years, the fruit fly Drosophila melanogaster has been one of the most
studied model organisms. Here, we present a single-cell atlas of the adult fly, Tabula …

Phosphorus is one of the most abundant elements preserved in earth, and it comprises a
fraction of ∼0.1% of the earth crust. In general, phosphorus has several allotropes, and the two …
