especially good for such channels and significantly outperform their binary
counterparts. Unfortunately, their decoding complexity is still large. In order
to reduce the d... | 1 | 0 | 0 | 0 | 0 | 0 |
Tunable coupling-induced resonance splitting in self-coupled Silicon ring cavity with robust spectral characteristics | We propose and demonstrate a self-coupled microring resonator for resonance
splitting by mutual mode coupling of cavity mode and counter-propagating mode
in Silicon-on-Insulator platform The resonator is constructed with a

High-precision measurements and theoretical calculations of indium excited-state polarizabilities | We report measurements of the $^{115}$In $7p_{1/2}$ and $7p_{3/2}$ scalar and
tensor polarizabilities using two-step diode laser spectroscopy in an atomic
beam. The scalar polarizabilities are one to two orders of magnitude larger
than for lower lying indium states due to the close proximity of the $7p$ and

2D reductions of the equation $u_{yy} = u_{tx} + u_yu_{xx} - u_xu_{xy}$ and their nonlocal symmetries | We consider the 3D equation $u_{yy} = u_{tx} + u_yu_{xx} - u_xu_{xy}$ and its
2D reductions: (1) $u_{yy} = (u_y+y)u_{xx}-u_xu_{xy}-2$ (which is equivalent to
the Gibbons-Tsarev equation) and (2) $u_{yy} = (u_y+2x)u_{xx} + (y-u_x)u_{xy}

An improved Belief Propagation algorithm finds many Bethe states in the random field Ising model on random graphs | We first present an empirical study of the Belief Propagation (BP) algorithm,

Large-scale diversity estimation through surname origin inference | The study of surnames as both linguistic and geographical markers of the past

Schur $Q$-functions and the Capelli eigenvalue problem for the Lie superalgebra $\mathfrak q(n)$ | Let $\mathfrak l:= \mathfrak q(n)\times\mathfrak q(n)$, where $\mathfrak
q(n)$ denotes the queer Lie superalgebra. The associative superalgebra $V$ of
type $Q(n)$ has a left and right action of $\mathfrak q(n)$, and hence is
equipped with a canonical $\mathfrak l$-module structure. We consider a

Dynamics of cosmological perturbations in modified Brans-Dicke cosmology with matter-scalar field interaction | In this work we focus on a novel completion of the well-known Brans-Dicke
theory that introduces an interaction between the dark energy and dark matter

cosmological accelerating solutions that fit Supernovae observations with great
precision withou... | 0 | 1 | 0 | 0 | 0 | 0 |
Attentive Convolutional Neural Network based Speech Emotion Recognition: A Study on the Impact of Input Features, Signal Length, and Acted Speech | Speech emotion recognition is an important and challenging task in the realm

Men Are from Mars, Women Are from Venus: Evaluation and Modelling of Verbal Associations | We present a quantitative analysis of human word association pairs and study

Galaxies as High-Resolution Telescopes | Recent observations show a population of active galaxies with milliarcseconds

Continuous CM-regularity of semihomogeneous vector bundles | We show that if $X$ is an abelian variety of dimension $g \geq 1$ and
${\mathcal E}$ is an M-regular coherent sheaf on $X$, the Castelnuovo-Mumford
regularity of ${\mathcal E}$ with respect to an ample and globally generated
line bundle ${\mathcal O}(1)$ on $X$ is at most $g$, and that equality is

Factorisation of the product of Dirichlet series of completely multiplicative functions | In the first chapter, we will present a computation of the square value of
the module of L functions associated to a Dirichlet character. This computation
suggests to ask if a certain ring of arithmetic multiplicative functions exists
and if it is unique. This search has led to the construction of that ring in

LAP: a Linearize and Project Method for Solving Inverse Problems with Coupled Variables | Many inverse problems involve two or more sets of variables that represent

Obtaining the Current-Flux Relations of the Saturated PMSM by Signal Injection | This paper proposes a method based on signal injection to obtain the
saturated current-flux relations of a PMSM from locked-rotor experiments. With
respect to the classical method based on time integration, it has the main
advantage of being completely independent of the stator resistance; moreover,
it is less sensit... | 1 | 0 | 0 | 0 | 0 | 0 |
Approximation properties of (p,q)-Meyer-Konig-Zeller Durrmeyer operators | In this paper, we introduce Durrmeyer type modification of Meyer-Konig-Zeller

Sequential detection of low-rank changes using extreme eigenvalues | We study the problem of detecting an abrupt change to the signal covariance

Does a growing static length scale control the glass transition? | Several theories of the glass transition propose that the structural
