Inverse regression for ridge recovery: A data-driven approach for parameter reduction in computer experiments | Parameter reduction can enable otherwise infeasible design and uncertainty
studies with modern computational science models that contain several input
parameters. In statistical regression, techniques for sufficient dimension

problem. A comput... | 0 | 0 | 1 | 0 | 0 | 0 |
Thermodynamics of Higher Order Entropy Corrected Schwarzschild-Beltrami-de Sitter Black Hole | In this paper, we consider higher order correction of the entropy and study
the thermodynamical properties of recently proposed Schwarzschild-Beltrami-de

Robust, high brightness, degenerate entangled photon source at room temperature | We report on a compact, simple and robust high brightness entangled photon
source at room temperature. Based on a 30 mm long periodically poled potassium

Emergence of superconductivity in the cuprates via a universal percolation process | A pivotal step toward understanding unconventional superconductors would be
to decipher how superconductivity emerges from the unusual normal state upon

Exploiting Spatial Degrees of Freedom for High Data Rate Ultrasound Communication with Implantable Devices | We propose and demonstrate an ultrasonic communication link using spatial

Global sensitivity analysis in the context of imprecise probabilities (p-boxes) using sparse polynomial chaos expansions | Global sensitivity analysis aims at determining which uncertain input

Agile Software Development Methods: Review and Analysis | Agile - denoting "the quality of being agile, readiness for motion,

Deep Learning: A Bayesian Perspective | Deep learning is a form of machine learning for nonlinear high dimensional

Tunnel-injected sub-260 nm ultraviolet light emitting diodes | We report on tunnel-injected deep ultraviolet light emitting diodes (UV LEDs)
configured with a polarization engineered Al0.75Ga0.25N/ In0.2Ga0.8N tunnel

Three-dimensional image reconstruction in J-PET using Filtered Back Projection method | We present a method and preliminary results of the image reconstruction in

Two-component domain decomposition scheme with overlapping subdomains for parabolic equations | An iteration-free method of domain decomposition is considered for
approximate solving a boundary value problem for a second-order parabolic

On the representation of finite convex geometries with convex sets | Very recently Richter and Rogers proved that any convex geometry can be

Resolving ultrafast exciton migration in organic solids at the nanoscale | The effectiveness of molecular-based light harvesting relies on transport of
optical excitations, excitons, to charg-transfer sites. Measuring exciton

semiconductors, common bulk ... | 0 | 1 | 0 | 0 | 0 | 0 |
Transfer Learning across Low-Resource, Related Languages for Neural Machine Translation | We present a simple method to improve neural translation of a low-resource

A Van-Der-Waals picture for metabolic networks from MaxEnt modeling: inherent bistability and elusive coexistence | In this work maximum entropy distributions in the space of steady states of
