Activity induced synchronization: Mutual flocking and chiral self-sorting
Synchronization, the temporal coordination of coupled oscillators, allows fireflies to flash in unison, neurons to fire collectively, and human crowds to fall in step on the London millenium bridge. Here, we interpret active (or self-propelled) chiral micr ...
2019Avoidance of Convex and Concave Obstacles with Convergence ensured through Contraction
This paper presents a closed-form approach to obstacle avoidance for multiple moving convex and star-shaped concave obstacles. The method takes inspiration in harmonic-potential fields. It inherits the convergence properties of harmonic potentials. We prov ...
2019Quantized Hall Conductance of a Single Atomic Wire: A Proposal Based on Synthetic Dimensions
We propose a method by which the quantization of the Hall conductance can be directly measured in the transport of a one-dimensional atomic gas. Our approach builds on two main ingredients: (1) a constriction optical potential, which generates a mesoscopic ...
2019Two-degrees-of-freedom (PID)-D-2 controller for precise nanopositioning in the presence of hardware-induced constant time delay
The fast and accurate tracking of periodic and arbitrary reference trajectories is the principal goal in many nanopositioning applications. Flexure-based piezoelectric stack driven nanopositioners are widely employed in applications where accurate mechanic ...
ELSEVIER SCIENCE INC2019Vibration tests on interconnected timber elements using wood-wood connections
Yves Weinand, Julien Gamerro, Jean-François Bocquet
Vibration tests were performed on 3 large-scale timber slabs using wood-wood connections with a span of 8.1 meters. 10 impulsive vibration tests per specimen were performed to estimate the initial natural frequency. Vibrations were triggered using a hammer ...
2019Horological oscillator
Simon Nessim Henein, Ilan Vardi, Etienne Frédéric Gabriel Thalmann, Mohammad Hussein Kahrobaiyan, Billy Nussbaumer
Horological oscillator comprising: - a first inertial body (141; 151; 1305; 1405; 1505; 301; 311; 314; 41; 51; 507; 529; 544; 541; 901; 903) arranged to rotate with respect to a first axis; - a second inertial body (143; 153; 1306; 1406; 1506; 302; 313; 31 ...
2019Harmonic Phasor Measurements in Real-World PMU-Based Acquisitions
Mario Paolone, Asja Derviskadic, Guglielmo Frigo
Modern distribution networks prove to be easily prone to power quality issues, and in particular to the presence of harmonic. components in the voltage and current signals, due to the increasing presence of nonlinear loads, distributed generation, and rene ...
IEEE2019The static and dynamic structural heterogeneities of B-DNA: extending Calladine-Dickerson rules
John Maddocks, Daiva Petkeviciute, Marco Pasi
We present a multi-laboratory effort to describe the structural and dynamical properties of duplex B-DNA under physiological conditions. By processing a large amount of atomistic molecular dynamics simulations, we determine the sequence-dependent structura ...
Oxford University Press (OUP)2019Floquet dynamics in the quantum measurement of mechanical motion
Tobias Kippenberg, Nicolas Piro Mastracchio, Liu Qiu, Itay Shomroni, Marie Adrienne Ioannou
The radiation-pressure interaction between one or more laser fields and a mechanical oscillator gives rise to a wide range of phenomena: From sideband cooling and backaction-evading measurements to ponderomotive and mechanical squeezing to entanglement and ...
AMER PHYSICAL SOC2019Getting the Right Twist: Influence of Donor-Acceptor Dihedral Angle on Exciton Kinetics and Singlet-Triplet Gap in Deep Blue Thermally Activated Delayed Fluorescence Emitter
Mohammad Khaja Nazeeruddin, Antonio Prlj, Kun-Han Lin, Nikita Drigo
Here, a novel deep blue emitter SBABz4 for use in organic light-emitting diodes (OLED) is investigated. The molecular design of the emitter enables thermally activated delayed fluorescence (TADF), which we examine by temperature-dependent time-resolved ele ...
