ABSTRACT Nonlinear mechanical vibrations under harmonic forcing can be well approximated by Fourier series. For a finite number of harmonics, the error is minimized over one period of vibration. This technique, known as multiharmonic balance method (MHBM), is today widely used in academics as well as industrial applications, e.g., for friction‐damped ...

ABSTRACT The existence of one or two strictly positive solutions of Neumann boundary value problems is studied in this paper where the nonlinearities are L1$$ {L}^1 $$‐Carathéodory functions, so they are not necessarily continuous. Additional weaker and better conditions than those used in previous results are posted on the nonlinearities to obtain ...

ABSTRACT Cryptocurrency markets are known for their wide price fluctuations, lack of central control, and fast‐paced development. These characteristics present serious challenges to traditional theories about how markets work and how prices reflect available information.

We report on new cobalt tetraphenylporphyrinate‐chitosan‐based microspheres developed for biosensing and anticancer therapy applications. We analyzed their second‐harmonic generation (SHG) behavior using a high‐resolution SHG microscope. In addition to the typical porphyrinate fluorescence, the microspheres exhibit a high‐intensity SHG response and ...

Investigating N2 Fixation Using a Bulky Fe(bisphosphine)2 Framework
The bulky Fe(0) N2 complex Fe(N2)(dibpe)2 has been prepared and efficiently produces NH3/N2H4 upon treatment with acid, similarly to previously investigated Fe(N2)(depe)2. However, it performs much less effectively during attempted catalytic N2 fixation, allowing investigation of the crucial role of steric hindrance in steps such as N2 binding and ...

Rapid Diagnostics of Reconfigurable Intelligent Surfaces Using Space‐Time‐Coding Modulation
A fast reconfigurable‐intelligent‐surface (RIS) diagnostics method is proposed based on spatio‐temporal modulation with orthogonal codes. Theoretical analysis demonstrates a clear distinction in code channel power between normal and faulty elements. Simulations validate its feasibility under high fault ratios and varying receiving angles.
