DAC-h3: A Proactive Robot Cognitive Architecture to Acquire and Express Knowledge About the World and the Self

Posted by klaurent MIT

Kavli Affiliate: Peter Ford | Summary:This paper introduces a cognitive architecture for a humanoid robot to engage in a proactive, mixed-initiative exploration and manipulation of its environment, where the initiative can originate from both the human and the robot. The framework, based on a biologically-grounded theory of the brain and mind, integrates a reactive interaction […]

Upper Limits on Gravitational Waves from Scorpius X-1 from a Model-Based Cross-Correlation Search in Advanced LIGO Data

Posted by klaurent Caltech

Kavli Affiliate: Mikhail G. Shapiro| First 5 Authors: The LIGO Scientific Collaboration, The LIGO Scientific Collaboration, , , | Summary:We present the results of a semicoherent search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1, using data from the first Advanced LIGO observing run. The search method uses details of the modelled, […]

Ring objects in the equivariant derived Satake category arising from Coulomb branches (with an appendix by Gus Lonergan)

Posted by klaurent Tokyo

Kavli Affiliate: Hiraku Nakajima | Summary:This is the second companion paper of arXiv:1601.03586. We consider the morphism from the variety of triples introduced in arXiv:1601.03586 to the affine Grassmannian. The direct image of the dualizing complex is a ring object in the equivariant derived category on the affine Grassmannian (equivariant derived Satake category). We show […]

Atomic-scale Structural and Chemical Characterization of Hexagonal Boron Nitride Layers Synthesized at the Wafer-Scale with Monolayer Thickness Control

Posted by klaurent Caltech

Kavli Affiliate: N. C. Yeh |Summary:Hexagonal boron nitride (h-BN) is a promising two-dimensional insulator with a large band gap and low density of charged impurities that is isostructural and isoelectronic with graphene. Here we report the chemical and atomic-scale structure of CVD-grown wafer-scale (~25 cm2) h-BN sheets ranging in thickness from 1-20 monolayers. Atomic-scale images […]

Leveraging Continuous Material Averaging for Inverse Electromagnetic Design

Posted by klaurent Berkeley

Kavli Affiliate: Eli Yablonovitch | Summary:Inverse electromagnetic design has emerged as a way of efficiently designing active and passive electromagnetic devices. This maturing strategy involves optimizing the shape or topology of a device in order to improve a figure of merit–a process which is typically performed using some form of steepest descent algorithm. Naturally, this […]

Inverse Design of Near Unity Efficiency Perfectly Vertical Grating Couplers

Posted by klaurent Berkeley

Kavli Affiliate: Eli Yablonovitch | Summary:Efficient coupling between integrated optical waveguides and optical fibers is essential to the success of integrated photonics. While many solutions exist, perfectly vertical grating couplers which scatter light out of a waveguide in the direction normal to the waveguide’s top surface are an ideal candidate due to their potential to […]

A Probabilistic Framework for Quantifying Biological Complexity

Posted by klaurent Stanford

Kavli Affiliate: Stuart Marshall | Summary:One thing that discriminates living things from inanimate matter is their ability to generate similarly complex or non-random architectures in a large abundance. From DNA sequences to folded protein structures, living cells, microbial communities and multicellular structures, the material configurations in biology can easily be distinguished from non-living material assemblies. […]

Damping parametric instabilities in future gravitational wave detectors by means of electrostatic actuators

Posted by klaurent MIT

Kavli Affiliate: Richard Mittleman | Summary:It has been suggested that the next generation of interferometric gravitational wave detectors may observe spontaneously excited parametric oscillatory instabilities. We present a method of actively suppressing any such instability through application of electrostatic forces to the interferometers’ test masses. Using numerical methods we quantify the actuation force required to […]

Core or cusps: The central dark matter profile of a redshift one strong lensing cluster with a bright central image

Posted by klaurent Stanford

Kavli Affiliate: Rafe Schindler | Summary:We report on SPT-CLJ2011-5228, a giant system of arcs created by a cluster at $z=1.06$. The arc system is notable for the presence of a bright central image. The source is a Lyman Break galaxy at $z_s=2.39$ and the mass enclosed within the 14 arc second radius Einstein ring is […]
