Data‐driven performance metrics for neural network learning

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView., 2023
Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

Bi@Sn Core–Shell Structure with Compressive Strain Boosts the Electroreduction of CO2 into Formic Acid

open access: yesAdvanced Science, 2020
As a profitable product from CO2 electroreduction, HCOOH holds economic viability only when the selectivity is higher than 90% with current density (j) over −200.0 mA cm−2.

Stabilizing copper sites in coordination polymers toward efficient electrochemical C-C coupling

open access: yesNature Communications, 2023
Typically, Cu catalysts agglomerate under electrochemical conditions. Here, the authors report a coordination polymer catalyst with neighboring Cu sites which remain isolated and reduce CO2 to C2H4 with high selectivity and ...

Electrochemical deposition as a universal route for fabricating single-atom catalysts

open access: yesNature Communications, 2020
While single-atom catalysts exhibit intriguing catalytic performances and electronic structures, syntheses are often tailored to a particular system. Here, authors report electrochemical deposition as a universal approach for the fabrication of single ...

Electrosynthesis of polymer-grade ethylene via acetylene semihydrogenation over undercoordinated Cu nanodots

open access: yesNature Communications, 2023
The removal of acetylene impurities remains important yet challenging to the ethylene downstream industry. Current thermocatalytic semihydrogenation processes require high temperature and excess hydrogen to guarantee complete acetylene conversion.

Quantum noise for Faraday light–matter interfaces [PDF]

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2012
In light matter interfaces based on the Faraday effect quite a number of quantum information protocols have been successfully demonstrated. In order to further increase the performance and fidelities achieved in these protocols a deeper understanding of the relevant noise and decoherence processes needs to be gained.

The Minimal CFL-Nuclear Interface [PDF]

open access: yes, 2001
At nuclear matter density, electrically neutral strongly interacting matter in weak equilibrium is made of neutrons, protons and electrons. At sufficiently high density, such matter is made of up, down and strange quarks in the color-flavor locked phase,
