Anomalous Magnetism for Dirac Electrons in Two Dimensional Rashba Systems | Spin-spin correlation function response in the low electronic density regime
and externally applied electric field is evaluated for 2D metallic crystals
under Rashba-type coupling, fixed number of particles and two-fold energy band
structure. Intrinsic Zeeman-like effect on electron spin polarization, density
of stat... | 0 | 1 | 0 | 0 | 0 | 0 |
Estimating Average Treatment Effects with a Double-Index Propensity Score | We consider estimating average treatment effects (ATE) of a binary treatment
in observational data when data-driven variable selection is needed to select
relevant covariates from a moderately large number of available covariates
$\mathbf{X}$. To leverage covariates among $\mathbf{X}$ predictive of the
outcome for ef... | 0 | 0 | 0 | 1 | 0 | 0 |
Emotion Detection and Analysis on Social Media | In this paper, we address the problem of detection, classification and
quantification of emotions of text in any form. We consider English text
collected from social media like Twitter, which can provide information having
utility in a variety of ways, especially opinion mining. Social media like
Twitter and Facebook... | 1 | 0 | 0 | 0 | 0 | 0 |
HotFlip: White-Box Adversarial Examples for Text Classification | We propose an efficient method to generate white-box adversarial examples to
trick a character-level neural classifier. We find that only a few
manipulations are needed to greatly decrease the accuracy. Our method relies on
an atomic flip operation, which swaps one token for another, based on the
gradients of the one... | 1 | 0 | 0 | 0 | 0 | 0 |
Towards fully commercial, UV-compatible fiber patch cords | We present and analyze two pathways to produce commercial optical-fiber patch
cords with stable long-term transmission in the ultraviolet (UV) at powers up
to $\sim$ 200 mW, and typical bulk transmission between 66-75\%. Commercial
fiber patch cords in the UV are of great interest across a wide variety of

Convex Parameterizations and Fidelity Bounds for Nonlinear Identification and Reduced-Order Modelling | Model instability and poor prediction of long-term behavior are common
problems when modeling dynamical systems using nonlinear "black-box"
techniques. Direct optimization of the long-term predictions, often called
simulation error minimization, leads to optimization problems that are
generally non-convex in the mode... | 1 | 0 | 1 | 0 | 0 | 0 |
Rydberg states of helium in electric and magnetic fields of arbitrary relative orientation | A spectroscopic study of Rydberg states of helium ($n$ = 30 and 45) in
magnetic, electric and combined magnetic and electric fields with arbitrary
relative orientations of the field vectors is presented. The emphasis is on two
special cases where (i) the diamagnetic term is negligible and both
paramagnetic Zeeman and... | 0 | 1 | 0 | 0 | 0 | 0 |
Change-point inference on volatility in noisy Itô semimartingales | This work is concerned with tests on structural breaks in the spot volatility
process of a general Itô semimartingale based on discrete observations
contaminated with i.i.d. microstructure noise. We construct a consistent test
building up on infill asymptotic results for certain functionals of spectral
spot volatilit... | 0 | 0 | 1 | 1 | 0 | 0 |
Double-diffusive erosion of the core of Jupiter | We present Direct Numerical Simulations of the transport of heat and heavy

planets ... | 0 | 1 | 0 | 0 | 0 | 0 |
Classifying Exoplanets with Gaussian Mixture Model | Recently, Odrzywolek and Rafelski (arXiv:1612.03556) have found three
distinct categories of exoplanets, when they are classified based on density.
We first carry out a similar classification of exoplanets according to their
density using the Gaussian Mixture Model, followed by information theoretic
criterion (AIC an... | 0 | 1 | 0 | 0 | 0 | 0 |
Competing effects of Hund's splitting and symmetry-breaking perturbations on electronic order in Pb$_{1-x}$Sn$_{x}$Te | We study the effect of a uniform external magnetization on p-wave
superconductivity on the (001) surface of the crystalline topological
insulator(TCI) Pb$_{1-x}$Sn$_{x}$Te. It was shown by us in an earlier work that
a chiral p-wave finite momentum pairing (FFLO) state can be stabilized in this

Partition function of Chern-Simons theory as renormalized q-dimension | We calculate $q$-dimension of $k$-th Cartan power of fundamental
representation $\Lambda_0$, corresponding to affine root of affine simply laced
Kac-Moody algebras, and show that in the limit $q\rightarrow 1 $, and with
natural renormalization, it is equal to universal partition function of

Task Recommendation in Crowdsourcing Based on Learning Preferences and Reliabilities | Workers participating in a crowdsourcing platform can have a wide range of

recommendation problem, in which tasks that best match a particular worker's
preferences and reliabilities are recommended to that worker. A task
recommendation scheme ... | 1 | 0 | 0 | 0 | 0 | 0 |
Elliptic Weight Functions and Elliptic q-KZ Equation | By using representation theory of the elliptic quantum group U_{q,p}(sl_N^),
we present a systematic method of deriving the weight functions. The resultant
sl_N type elliptic weight functions are new and give elliptic and dynamical
analogues of those obtained in the trigonometric case. We then discuss some

Formal duality in finite cyclic groups | The notion of formal duality in finite Abelian groups appeared recently in
relation to spherical designs, tight sphere packings, and energy minimizing
configurations in Euclidean spaces. For finite cyclic groups it is conjectured

Nonlinear Dynamics of Binocular Rivalry: A Comparative Study | When our eyes are presented with the same image, the brain processes it to
view it as a single coherent one. The lateral shift in the position of our
eyes, causes the two images to possess certain differences, which our brain

Nonstandard Analysis and Constructivism! | Almost two decades ago, Wattenberg published a paper with the title

Text-Independent Speaker Verification Using 3D Convolutional Neural Networks | In this paper, a novel method using 3D Convolutional Neural Network (3D-CNN)
architecture has been proposed for speaker verification in the text-independent

of the previously-reported approaches create speaker models based on averaging

Sequential identification of nonignorable missing data mechanisms | With nonignorable missing data, likelihood-based inference should be based on

Image Stitching by Line-guided Local Warping with Global Similarity Constraint | Low-textured image stitching remains a challenging problem. It is difficult
