Multiple domestications of asian rice
In their recent Correspondence about our study showingthat there were three origins of Asian rice2, Huang and Han suggest that the
methodology that we used to infer multiple domestications was flawed as it did not take account of the strong genetic bottleneck in japonica

Deformable Part-based Fully Convolutional Network for Object Detection
Existing region-based object detectors are limited to regions with fixed box
geometry to represent objects, even if those are highly non-rectangular. In
this paper we introduce DP-FCN, a deep model for object detection which
explicitly adapts to shapes of objects with deformable parts. Without
additional annotations, it learns to focus on discriminative elements and to
align them, and simultaneously brings more invariance for classification and
geometric information to refine localization. DP-FCN is composed of three main
modules: a Fully Convolutional Network to efficiently maintain spatial
resolution, a deformable part-based RoI pooling layer to optimize positions of
parts and build invariance, and a deformation-aware localization module
explicitly exploiting displacements of parts to improve accuracy of bounding
box regression. We experimentally validate our model and show significant
gains. DP-FCN achieves state-of-the-art performances of 83.1% and 80.9% on
PASCAL VOC 2007 and 2012 with VOC data only.Comment: Accepted to BMVC 2017 (oral
Numerical Simulation of Single-Electron Tunneling in Random Arrays of Small Tunnel Junctions Formed by Percolation of Conductive Nanoparticles
We numerically simulated electrical properties, i.e., the resistance and Coulomb blockade threshold, of randomly-placed conductive nanoparticles. In simulation, tunnel junctions were assumed to be formed between neighboring particle-particle and particle-electrode connections. On a plane of triangle 100Γ100 grids, three electrodes, the drain, source, and gate, were defined. After random placements of conductive particles, the connection between the drain and source electrodes were evaluated with keeping the gate electrode disconnected. The resistance was obtained by use of a SPICE-like simulator, whereas the Coulomb blockade threshold was determined from the current-voltage characteristics simulated using a Monte-Carlo simulator. Strong linear correlation between the resistance and threshold voltage was confirmed, which agreed with results for uniform one-dimensional arrays
Logophoricity and Mandarin Exempt Reflexives
Anaphors in many languages do not obey the \u27canonical\u27 Binding Condition A (Chomsky 1986), such as Icelandic \u27sig\u27 and Mandarin \u27ziji\u27. Two main competing approaches have been proposed to capture binding beyond the local domain: (i) The LONG-DISTANCE BINDING (LDB) theory derives non-local binding via covert cyclic movement and turns non-local binding into local binding which always obeys Condition A. (Pica 1987, Huang & Tang 1991) (ii) The LOGOPHORICITY (LOG) theory explains exempt anaphors by logophoric rather than pure structural constraints (Sells 1987, Huang & Liu 2001, Charnavel 2019). The two theories make distinct predictions on the referential dependencies between reflexives and their antecedents. The LDB theory predicts that antecedents should always c-command the reflexives, while the LOG theory predicts that reflexives need not be c-commanded by their antecedents if they are logophoric. This paper aims to experimentally test the two competing theories by investigating the binding conditions of Chinese reflexive \u27ziji\u27 and \u27taziji\u27 using acceptability judgment tasks. The results about \u27ziji\u27 support the LOG theory against the LDB theory. Furthermore, our results reveal that \u27taziji\u27, though usually considered as a local anaphor (e.g., Cole, Hermon & Huang 2006), can in fact similarly be exempt from binding under logophoric conditions
The universal DAHA of type and Leonard triples
Assume that is an algebraically closed field and is a nonzero
scalar in that is not a root of unity. The universal Askey--Wilson
algebra is a unital associative -algebra generated by
and the relations state that each of is central in . The universal DAHA
of type is a unital associative -algebra generated by and the relations state that
\begin{gather*} t_it_i^{-1}=t_i^{-1} t_i=1 \quad \hbox{for all }; \\
\hbox{ is central} \quad \hbox{for all }; \\
t_0t_1t_2t_3=q^{-1}. \end{gather*} It was given an -algebra
homomorphism that sends \begin{eqnarray*} A
&\mapsto & t_1 t_0+(t_1 t_0)^{-1}, \\ B &\mapsto & t_3 t_0+(t_3 t_0)^{-1}, \\ C
&\mapsto & t_2 t_0+(t_2 t_0)^{-1}. \end{eqnarray*} Therefore any -module can be considered as a -module. Let denote a
finite-dimensional irreducible -module. In this paper we show
that are diagonalizable on if and only if act as Leonard
triples on all composition factors of the -module .Comment: arXiv admin note: text overlap with arXiv:2003.0625
