Weak behaviour of Fourier-Neumann series [PDF]

, 2003
Let Jμ denote the Bessel function of order μ. The functions x-α-1 Jα+2n+1(x), n = 0, 1, 2, ..., form an orthogonal system in the space L2((0, ∞), x2α+1 dx) when α > -1.

Beyond Primary Nucleation: Molecular Basis of Peptide Crystal Secondary Nucleation at Soft Interface

Advanced Functional Materials, EarlyView.
High spatiotemporal‐resolution atomic force microscopy directly resolved peptide secondary nucleation (SN) and growth characteristics and mechanisms on HOPG. The landscape of peptide nucleation sites, growth dynamics, molecular‐scale structures, phase transitions, and cross‐seeding processes were realized.

Heteroengineering‐Induced Electronic Reconstruction for Ammonium‐Ion Energy Storage

Advanced Functional Materials, EarlyView.
An integrated electronic reconstruction behavior is induced by local heteroengineering on VO2(B) electrode material surface of NH4+ supercapacitor, rationally modulating the electronic structure, enabling enhanced intrinsic conductivity and extra driving force for NH4+ intercalation reaction.

Fourier Correlations of Dam Horizontal Movements Time Series [PDF]

Journal of Electrical and Electronics Engineering, 2008
Time deformations monitoring of Drăgandam is done by physically methods (i.e. inversependulum) and topographically methods (i.e.optoelectronic). The two deformations measuringsystems, built up by these two methods, are different.The existence of ...
