Empirical Analysis of the Necessary and Sufficient Conditions of the Echo State Property

, 2017
The Echo State Network (ESN) is a specific recurrent network, which has gained popularity during the last years. The model has a recurrent network named reservoir, that is fixed during the learning process.

Topological Defects in Carbon Matrix Are Efficiently Constructed by Joule Thermal Shock for Catalyzing the Growth of Carbon Nanotubes

Advanced Science, EarlyView.
The Joule thermal shock technique ensures the efficient construction of topological defects in the carbon matrix because the instantaneous cooling suppresses the graphitization rearrangement of the heteroatom removal sites. This topological defect carbon can activate carbon source molecules by electron transfer, and further grow into carbon nanotubes ...

Wide Band Gap Boron Nitride Nanodots‐Incorporated Polyetherimide Dielectrics for High‐Temperature Dielectric Energy Storage

Advanced Science, EarlyView.
The inherent conjugation effects between molecular chains in PEI dielectrics induce substantial energy loss escalation at elevated temperatures. This study incorporated BNNDs into PEI films, successfully achieving effective capture of motion charges under high‐temperature conditions.

Methylation‐Induced Permanent Charge Polarization in Covalent Organic Frameworks for Visible Light‐Driven Water Decontamination and Disinfection

Advanced Science, EarlyView.
A targeted in situ methylation strategy is developed to engineer cationic centers in a quinoline‐linked COF (NQ‐COFS1‐Me), creating a strong built‐in electric field, which effectively suppresses excitonic effects and promotes charge separation. The optimized material demonstrates powerful photocatalytic ROS generation for rapid bacterial inactivation ...

Zero bias transformation and asymptotic expansions II : the Poisson case [PDF]

, 2009
We apply a discrete version of the methodology in \cite{gauss} to obtain a recursive asymptotic expansion for $\esp[h(W)]$ in terms of Poisson expectations, where $W$ is a sum of independent integer-valued random variables and $h$ is a polynomially ...

Electronic Modulation of K⁺‐Intercalated Polymeric Carbon Nitride via ─C≡N/─OH Functionalization for Efficient Photocatalytic H2O2 Production

Advanced Science, EarlyView.
K+ is successfully embedded in the PCN interlayers via a high‐temperature polymerization. The incorporation of K+ perturbs the local electronic structure via interaction with nitrogen lone pairs, narrowing the PCN bandgap, which exhibits superior photocatalytic performance, achieving a high H2O2 generation rate both in situ and under sunlight ...

AN UPDATED FRAMEWORK OF ESP PROGRAM EVALUATION [PDF]

, 2016
though considered as important, ESP program evaluation remains the “roads less taken” stage compared to need analysis. Whereas, program evaluation is needed to measure the effectiveness of the current program as well as to plan a revised program which ...

Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

Advanced Science, EarlyView.
Chromosome segregation in Streptococcus pneumoniae depends on RocS, a bitopic protein whose membrane‐anchoring mechanisms were unclear. Using NMR and AFM, this study reveals that the widely conserved RocS anchor binds to membranes via a conserved kink‐helix motif which inserts into lipid nanodomains.

Técnicas quirúrgicas utilizadas en la corrección del entropión

Multimed, 2017
RESUMEN En las personas de edad avanzada, el entropión generalmente se produce por un espasmo muscular y el debilitamiento de los tendones cantales que sostienen el párpado. Las técnicas quirúrgicas en la cirugía del entropión varían según la etiología
