In this short note, we prove two properties of symplectic pairs on a four-manifold: firstly we prove that two transversal orientable foliations of codimension two, which are taut for the same Riemannian metric, are the characteristic foliations of a...
Typically, cavities of sub-terahertz electron cyclotron masers (gyrotrons) have oversized dimensions. That leads to a problem of the dense mode spectrum and, as a result, to a problem of the mode selectivity in the process of realization of gyrotrons...
With the attention focused on harvesting energy from the ambient environment for nanoscale electronic devices, electromechanical coupling effects in materials have been studied for many potential applications. Flexoelectricity can be observed in all...
The water level at ports governs under-keel clearance, pilotage windows, cargo operations and local flood risk, yet regional ocean forecasting systems resolve it at kilometre scales that may lie outside the harbour basin. This study evaluates a stati...
Coherent sampling and ultra-pure signal sources are two major bottlenecks limiting the mass-production deployment of high-resolution dynamic testing of analog-to-digital converters (ADCs). The principal contribution of this study is the Multi-Amplitu...
Spherical structures of dielectric and magnetic materials are studied intensively in basic research and employed widely in applications. The polarization, (P for dielectric and M for magnetic materials), is the parent physical vector of all relevant...
We investigate the modeling capabilities of sets of coupled classical harmonic oscillators (CHO) in the form of a modeling game. The application of the simple but restrictive rules of the game lead to conditions for an isomorphism between Lie-algebra...
Recombinant proteins are used to characterize parasite enzymes, membrane proteins, antigens, and protein complexes, but some targets are difficult to recover in a soluble and functional form. Expression can be affected by codon usage, intrinsically d...
We consider a two-component linearly coupled system with the intrinsic cubic nonlinearity and the harmonic-oscillator (HO) confining potential. The system models binary settings in BEC and optics. In the symmetric system, with the HO trap acting in b...
This manuscript examines the rotational dynamics of rigid bodies in five-dimensional Euclidean space. This results in ten coupled nonlinear differential equations for angular velocities. Restricting rotations along certain axes reduces the 5D equatio...
Two-dimensional transition metal dichalcogenides have attracted considerable attention in electrocatalytic hydrogen evolution due to their unique layered structures and tunable electronic properties. However, prior research has predominantly focused...
Accurate forecasting of ratio and phase errors of 10 kV current transformers (CTs) is difficult under distorted and time-varying conditions due to mixed harmonics, ambient-driven drifts, and limited reference-grade field data. This paper proposes a r...
Driven by needs in neuroscientific research, future neural interface technologies demand integrated circuits that can record a large number of channels of neural signals in parallel while maintaining a miniaturized physical form factor. Using convent...
