QD-learning: A collaborative distributed strategy for multi-agent reinforcement learning through consensus + innovations

open access: yes, 2013
The paper considers a class of multi-agent Markov decision processes (MDPs), in which the network agents respond differently (as manifested by the instantaneous one-stage random costs) to a global controlled state and the control actions of a remote ...

Improvement in Color-Conversion Efficiency and Stability for Quantum-Dot-Based Light-Emitting Diodes Using a Blue Anti-Transmission Film

open access: yesNanomaterials, 2018
In this report, a blue anti-transmission film (BATF) has been introduced to improve the color-conversion efficiency (CCE) and the stability of quantum dot (QD) films. The results indicate that the CCE can be increased by as much as 93% using 15 layers of

Comparison of the anti-colitis activities of Qing Dai/Indigo Naturalis constituents in mice

open access: yesJournal of Pharmacological Sciences, 2020
Qing Dai/Indigo Naturalis (QD) has been shown to ameliorate ulcerative colitis (UC) in clinical trials; however, its mechanism remains elusive. This study investigates the effects of QD on murine dextran sulfate sodium salt-induced colitis.

Converter-aware wavelength assignment in WDM networks with limited-range conversion capability

open access: yes, 2006
In wavelength-routed optical networks, wavelength converters are considered as one of the most critical network resources because they can significantly reduce the blocking probability, but still remain quite expensive. Unfortunately, previous wavelength

Developing The Performance of Double Quantum Dot Solar Cell Structure

open access: yesمجلة علوم ذي قار, 2021
This work proposes a double quantum dot (QD) structure as an intermediate band for developing solar (SC) performance. The density matrix (DEMs) are written for this system, where coupled with the continuity-current equation and solved numerically to ...

Toxicity of quantum dots and cadmium to rainbow trout (Oncorhynchus mykiss) in early ontogenesis

open access: yesFrontiers in Marine Science, 2015
The aim of the study was to investigate toxic effects of CdSe/ZnS-COOH quantum dots (QD) and cadmium (Cd) on biological parameters of rainbow trout (Oncorhychus mykiss) in its early stages of development (embryos and larvae). It was found that short-term

Influence Of The Qd Luminescence Quantum Yield On Photocurrent In Qd/graphene Hybrid Structures [PDF]

open access: yes, 2017
Photoinduced changes in luminescent and photoelectrical properties of the hybrid structure based on CdSe/ZnS QDs and multilayer graphene nanobelts were studied. It was shown that an irradiation of the structures by 365 nm mercury line in doses up to 23 J
