A Predictive Model of the Position of Plasmapause Based on Lunar Phase and Deep Learning Framework

open access: yesGeophysical Research Letters
The plasmapause position is crucial for understanding magnetospheric dynamics and space weather forecasting. This study pioneers the integration of lunar phase (LP) into plasmapause modeling using two neural network architectures (BP and fully connected ...

Bioactive Conductive Ti3C2Tx‐Ce Hydrogel Facilitates Spinal Cord Injury Repair Through ROS Scavenging and Mitochondrial Regulation

open access: yesAdvanced Functional Materials, EarlyView.
Bioactive conductive Ti3C2Tx‐Ce hydrogels with with scavenging ROS and alleviating neuronal mitochondrial dysfunction are exploited for SCI treatment. This functionality is attributed to interfacial activation modification of Ti3C2Tx with Ce3+ ions to in‐situ form Ce(OH)x‐mediated protective layer, which is beneficial to enabling stable intracellular ...

On Some New Generalized Difference Sequence Spaces of Nonabsolute Type

open access: yesJournal of Mathematics, 2014
We define a new triangle matrix W^=(wnkλ) by the composition of the matrices Λ=(λnk) and B(r,s,t). Also, we introduce the sequence spaces c0λ(B^),cλ(B^),l∞λ(B^), and lpλ(B^) by using matrix domain of the matrix W^ on the classical sequence spaces c0,c,l∞,

The quotient shapes of lp and Lp spaces

open access: yesRad Hrvatske akademije znanosti i umjetnosti Matematičke znanosti, 2018
All lp spaces (over the same field), p ≠ ∞, have the finite quotient shape type of the Hilbert space l2. It is also the finite quotient shape type of all the subspaces lp(p'), p < p' ≤ ∞, as well as of all their direct sum subspaces F0N(p'), 1 ≤ p' ≤ ∞. Furthermore, their countable and finite quotient shape types coincide.

Balancing Electrons to Break the Activity‐Selectivity Trade‐Off in H2O2 Electrosynthesis

open access: yesAdvanced Functional Materials, EarlyView.
Carrier‐concentration balancing in CuS is achieved by coupling cobalt dopants with cobalt vacancies, converting CuS from p‐ to n‐type to accelerate 2e− ORR while withdrawing excess carriers to optimize *OOH binding for H2O2 desorption. The catalyst reaches 8.14 mol g−1 h−1 with >84% selectivity in 1.0 M KOH and drives robust electro‐Fenton dye ...

Fréchet Envelopes of Nonlocally Convex Variable Exponent Hörmander Spaces

open access: yesAbstract and Applied Analysis, 2016
We show that the dual Bp·locΩ′ of the variable exponent Hörmander space Bp(·)loc(Ω) is isomorphic to the Hörmander space B∞c(Ω) (when the exponent p(·) satisfies the conditions ...

Giant Intrinsic Chirality Amplification of Aqueous Lead Halide Perovskite Nanocrystals via H‐Bond Driven Self‐Assembly Superstructures

open access: yesAdvanced Functional Materials, EarlyView.
Water‐assisted monoclinic CsPbBr3 transformation strategy is applied for synthesizing aqueous CsPbBr3/CsPb2Br5 nanocrystals with superior water‐repellent and excellent optical property. Low temperature enhanced hydrogen bonding network self‐assembled CsPbBr3/CsPb2Br5 nanocrystals into asymmetric superstructures, which exhibit notable circularly ...

On a family of Wiener type spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
Research on Wiener type spaces was initiated by N.Wiener in [15]. A number of authors worked on these spaces or some special cases of these spaces. A kind of generalization of the Wiener's definition was given by H.Feichtinger in [2] as a Banach spaces ...
