minimal free resolution of the ideal of a general set of points on an
irreducible projective algebraic variety. For surfaces in $\mathbb P^3$ this
conjecture has been proven for points on quadric surfaces and on general cubic
surfaces. In the latter c... | 0 | 0 | 1 | 0 | 0 | 0 |
Exact density functional obtained via the Levy constrained search | A stochastic minimization method for a real-space wavefunction, $\Psi({\bf
r}_{1},{\bf r}_{2}\ldots{\bf r}_{n})$, constrained to a chosen density,

Compile-Time Symbolic Differentiation Using C++ Expression Templates | Template metaprogramming is a popular technique for implementing compile time

On Multilingual Training of Neural Dependency Parsers | We show that a recently proposed neural dependency parser can be improved by
joint training on multiple languages from the same family. The parser is
implemented as a deep neural network whose only input is orthographic

discover how linguist... | 1 | 0 | 0 | 0 | 0 | 0 |
Autocommuting probability of a finite group | Let $G$ be a finite group and $\Aut(G)$ the automorphism group of $G$. The
autocommuting probability of $G$, denoted by $\Pr(G, \Aut(G))$, is the
probability that a randomly chosen automorphism of $G$ fixes a randomly chosen
element of $G$. In this paper, we study $\Pr(G, \Aut(G))$ through a
generalization. We obtain... | 0 | 0 | 1 | 0 | 0 | 0 |
Inside-Out Planet Formation. IV. Pebble Evolution and Planet Formation Timescales | Systems with tightly-packed inner planets (STIPs) are very common. Chatterjee

SilhoNet: An RGB Method for 3D Object Pose Estimation and Grasp Planning | Autonomous robot manipulation often involves both estimating the pose of the

Collapsed Tetragonal Phase Transition in LaRu$_2$P$_2$ | The structural properties of LaRu$_2$P$_2$ under external pressure have been
studied up to 14 GPa, employing high-energy x-ray diffraction in a

Bayesian Nonparametric Unmixing of Hyperspectral Images | Hyperspectral imaging is an important tool in remote sensing, allowing for

Dynamical control of electron-phonon interactions with high-frequency light | This work addresses the one-dimensional problem of Bloch electrons when they

Controlling the thermoelectric effect by mechanical manipulation of the electron's quantum phase in atomic junctions | The thermoelectric voltage developed across an atomic metal junction (i.e., a

Improving Protein Gamma-Turn Prediction Using Inception Capsule Networks | Protein gamma-turn prediction is useful in protein function studies and

is the limited capacity... | 0 | 0 | 0 | 0 | 1 | 0 |
Image transformations on locally compact spaces | An image is here defined to be a set which is either open or closed and an
