TL;DR: Lactide polymerization is a reversible reaction, and the concentration of lactide in PLA at equilibrium is ~3 wt% at 180 °C. Devolatilization of PLA can reduce residual lactide monomer concentration to <0.3 wt%.

The concentration of lactide in polylactide (PLA) at equilibrium is ~3 wt% at 180 °C. Devolatilization of PLA is capable of lowering residual lactide monomer concentration to <0.3 wt%. PRINCIPLE

Heisenberg-Limited Atom Clocks Based on Entangled Qubits
Eric Kessler,Peter Komar,Michael Bishof,Liang Jiang,Anders S. Sørensen,Jun Ye,Mikhail D. Lukin +6 more
TL;DR: A quantum-enhanced atomic clock protocol based on groups of sequentially larger Greenberger-Horne-Zeilinger states that achieves the best clock stability allowed by quantum theory up to a logarithmic correction is presented.
Quantum eigenvalue estimation via time series analysis
TL;DR: Unlike the well-known quantum phase estimation algorithm that uses the quantum Fourier transform, this method does not require large ancillary systems, large sequences of controlled operations, or preserving coherence between experiments, and is therefore more attractive for near-term applications.
Complex paths around the sign problem
TL;DR: In this article , a potential solution to the sign problem is proposed to deformation of the manifold on which the problem is defined, in order to reduce the instabilities of sign problems.

The Digital Regime of Truth: From the Algorithmic Governmentality to a New Rule of Law
TL;DR: In the first part of the debate as discussed by the authors, Stiegler discussed with the Belgian legal philosopher Antoinette Rouvroy, based at the University of Namur, and who developed in the last few years a new line of inquiry around what she called with Thomas Berns "algorithmic governmentality".

TL;DR: In this paper, the authors describe a principle to determine which features of an object will be easy to reconstruct from limited X-ray CT data and which will be difficult, depending on the geometry of the data set.

Scale & Affine Invariant Interest Point Detectors
TL;DR: A comparative evaluation of different detectors is presented and it is shown that the proposed approach for detecting interest points invariant to scale and affine transformations provides better results than existing methods.

The Companion Species Manifesto : Dogs, People, and Significant Otherness
Donna Haraway
- 01 Apr 2003
TL;DR: The Companion Species Manifesto as discussed by the authors is about the implosion of nature and culture in the joint lives of dogs and people, who are bonded in significant otherness, in all their historical complexity, Donna Haraway tells us, dogs are not surrogates for theory, she says; they are not here just to think with.

Scale-Space Theory : A Basic Tool for Analysing Structures at Different Scales
TL;DR: In this paper, an inherent property of objects in the world is that they only exist as meaningful entities over certain ranges of scale, and if one aims at describing the structure of unknown real-world signals, then...
Edge detection and ridge detection with automatic scale selection
Tony Lindeberg
- 18 Jun 1996
TL;DR: A mechanism is presented for automatic selection of scale levels when detecting one-dimensional features, such as edges and ridges, and a novel concept of a scale-space edge is introduced.
