Continuous Tensor Train-Based Dynamic Programming for High-Dimensional Zero-Sum Differential Games
(IEEE, 2018-06)© 2018 AACC. Zero-sum differential games constitute a prominent research topic in several fields ranging from economics to motion planning. Unfortunately, analytical techniques for differential games can address only simple, ... -
Continuous time channels with interference
(Institute of Electrical and Electronics Engineers (IEEE), 2012-08)Khanna and Sudan [2] studied a natural model of continuous time channels where signals are corrupted by the effects of both noise and delay, and showed that, surprisingly, in some cases both are not enough to prevent such ... -
Continuous Topological Phase Transition between Two 1D Antiferromagnetic Spin-1 Boson Superfluids with the Same Symmetry
(American Physical Society (APS), 2019)© 2019 American Physical Society. Spin-1 bosons on a one-dimensional chain, at incommensurate filling with an antiferromagnetic spin interaction between neighboring bosons, may form a spin-1 boson condensed state that ... -
Continuous Trajectory Planning of Mobile Sensors for Informative Forecasting
(2010-06)This paper addresses planning of continuous paths for mobile sensors to reduce uncertainty in some quantities of interest in the future. The mutual information between the continuous measurement path and the future ... -
Continuous transitions between composite Fermi liquid and Landau Fermi liquid: A route to fractionalized Mott insulators
(American Physical Society, 2012-08)One of the most successful theories of a non-Fermi-liquid metallic state is the composite Fermi-liquid (CFL) theory of the half-filled Landau level. In this paper, we study continuous quantum phase transitions out of the ... -

Continuous-flow precipitation of hydroxyapatite in ultrasonic microsystems
(Elsevier BV, 2012-11)This paper describes the continuous-flow precipitation of hydroxyapatite Ca[subscript 5](PO[subscript 4])[subscript 3]OH (HAp) in two ultrasonic microreactors using diluted aqueous solutions of calcium and phosphate at ... -
Continuous-Flow Production of Succinic Anhydrides via Catalytic β-Lactone Carbonylation by Co(CO) 4 ⊂Cr-MIL-101
(American Chemical Society (ACS), 2018)© 2018 American Chemical Society. Industrial synthesis of succinic acid relies on hydrocarbon oxidation or biomass fermentation routes that suffer from energy-costly separation processes. Here we demonstrate an alternate ... -
Continuous-flow synthesis and purification of atropine with sequential in-line separations of structurally similar impurities

CONTINUOUS-TIME AVERAGE-PRESERVING OPINION DYNAMICS WITH OPINION-DEPENDENT COMMUNICATIONS
(Society for Industrial and Applied Mathematics, 2010-10)We study a simple continuous-time multiagent system related to Krause's model of opinion dynamics: each agent holds a real value, and this value is continuously attracted by every other value differing from it by less than ... -
Continuous-variable quantum enigma machines for long-distance key distribution
(American Physical Society, 2015-12)Quantum physics allows for unconditionally secure communication through insecure communication channels. The achievable rates of quantum-secured communication are fundamentally limited by the laws of quantum physics and ... -
