In situ high resolution real-time quantum efficiency imaging for photocathodes | Aspects of the preparation process and performance degradation are two major
problems of photocathodes. The lack of a means for dynamic quantum efficiency
measurements results in the inability to observe the inhomogeneity of the
cathode surface by fine structural analysis and in real time.Here we present a
simple and... | 0 | 1 | 0 | 0 | 0 | 0 |
Competitive division of a mixed manna | A mixed manna contains goods (that everyone likes), bads (that everyone
dislikes), as well as items that are goods to some agents, but bads or satiated
to others.
If all items are goods and utility functions are homothetic, concave (and
monotone), the Competitive Equilibrium with Equal Incomes maximizes the Nash

Understanding Black-box Predictions via Influence Functions | How can we explain the predictions of a black-box model? In this paper, we
use influence functions -- a classic technique from robust statistics -- to
trace a model's prediction through the learning algorithm and back to its
training data, thereby identifying training points most responsible for a given
prediction. T... | 1 | 0 | 0 | 1 | 0 | 0 |
Linear and nonlinear photonic Jackiw-Rebbi states in waveguide arrays | We study analytically and numerically the optical analogue of the
Jackiw-Rebbi states in quantum field theory. These solutions exist at the
interface of two binary waveguide arrays which are described by two Dirac
equations with opposite sign masses. We show that these special states are
topologically robust not only... | 0 | 1 | 0 | 0 | 0 | 0 |
A Century of Science: Globalization of Scientific Collaborations, Citations, and Innovations | Progress in science has advanced the development of human society across

cloning, and artificial intelligence, among the many scientific achievements
produced in the 20th century. However, the way that science advances itself is
much less well-u... | 1 | 1 | 0 | 0 | 0 | 0 |
Interval-type theorems concerning means | Each family $\mathcal{M}$ of means has a natural, partial order (point-wise
order), that is $M \le N$ iff $M(x) \le N(x)$ for all admissible $x$.
In this setting we can introduce the notion of interval-type set (a subset

Diff-DAC: Distributed Actor-Critic for Average Multitask Deep Reinforcement Learning | We propose a fully distributed actor-critic algorithm approximated by deep
neural networks, named \textit{Diff-DAC}, with application to single-task and
to average multitask reinforcement learning (MRL). Each agent has access to
data from its local task only, but it aims to learn a policy that performs well

On locally compact semitopological $0$-bisimple inverse $ω$-semigroups | We describe the structure of Hausdorff locally compact semitopological

particular, we show that a Hausdorff locally compact semitopological
$0$-bisimple inverse $\omega$-semigroup with a compact maximal subgroup is

Theory of Disorder-Induced Half-Integer Thermal Hall Conductance | Electrons that are confined to a single Landau level in a two dimensional
electron gas realize the effects of strong electron-electron repulsion in its
purest form. The kinetic energy of individual electrons is completely quenched

remarkable cons... | 0 | 1 | 0 | 0 | 0 | 0 |
On Security Research Towards Future Mobile Network Generations | Over the last decades, numerous security and privacy issues in all three

Channel Simulation in Quantum Metrology | In this review we discuss how channel simulation can be used to simplify the

Ranking Causal Influence of Financial Markets via Directed Information Graphs | A non-parametric method for ranking stock indices according to their mutual
causal influences is presented. Under the assumption that indices reflect the
underlying economy of a country, such a ranking indicates which countries exert

Shear banding in metallic glasses described by alignments of Eshelby quadrupoles | Plastic deformation of metallic glasses performed well below the glass
transition temperature leads to the formation of shear bands as a result of
shear localization. It is believed that shear banding originates from
individual stress concentrators having quadrupolar symmetry. To elucidate the
underlying mechanisms o... | 0 | 1 | 0 | 0 | 0 | 0 |
Detection of low dimensionality and data denoising via set estimation techniques | This work is closely related to the theories of set estimation and manifold

Our object of interest is a, possibly lower-dimensional, compact set $S

The general aim is to identify (via stochastic procedures) some qualitative
or quantitative features of $S$, of geometric or topologic... | 0 | 0 | 1 | 1 | 0 | 0 |
Deep Networks with Shape Priors for Nucleus Detection | Detection of cell nuclei in microscopic images is a challenging research

recent success s... | 0 | 0 | 0 | 1 | 0 | 0 |
A sheaf-theoretic model for SL(2,C) Floer homology | Given a Heegaard splitting of a three-manifold Y, we consider the SL(2,C)

Discriminative models for multi-instance problems with tree-structure | Modeling network traffic is gaining importance in order to counter modern

full. Obt... | 1 | 0 | 0 | 0 | 0 | 0 |
Functional advantages offered by many-body coherences in biochemical systems | Quantum coherence phenomena driven by electronic-vibrational (vibronic)

Modeling stochastic skew of FX options using SLV models with stochastic spot/vol correlation and correlated jumps | It is known that the implied volatility skew of FX options demonstrates a

Computational Study of Amplitude-to-Phase Conversion in a Modified Uni-Traveling Carrier (MUTC) Photodetector | We calculate the amplitude-to-phase (AM-to-PM) noise conversion in a modified

the experiments, and we explain their origin. The nulls appear due to the
transit time variation when the average photocurrent varies, and the transit
