Polarization invariance in beam propagation.

Published: December 2007

It has been known for some time that the degree of polarization of a light beam may change on propagation, even in free space. In this Letter we derive sufficiency conditions for the degree of polarization of a beam generated by a uniformly polarized stochastic, electromagnetic source of a wide class to be the same throughout the far zone and in the source plane.

As a novel protein post-translational modification, lysine succinylation is widely involved in metabolism regulation. To describe succinylated lysine's physiological functions and distribution patterns in Saccharopolyspora erythraea, a large and global protein succinylome was identified in a hypersuccinylated strain E3ΔsucC, using high-resolution 4D label-free mass spectrometry. Bioinformatic analysis was conducted to examine the succinylated proteins further in this study.

Context: This article mainly studies three isomers of CHNO, namely 5-methyl-3,4-dinitro-1- (trinitromethyl) -1H pyrazole (1), 4-methyl-3,5-dinitro-1- (trinitromethyl) -1H pyrazole (2), and 3,5-bis (dinitromethyl) -4-nitro-1H-pyrazole (3). These three substances are excellent candidates for energetic materials, but their properties under external electric fields (EEF) have not been studied. Therefore, this article studied the properties of three isomers under EEF using density functional theory (DFT), and conducted statistical analysis on the obtained data, including the molecular structure, frontier molecular orbitals, surface electrostatic potential, and nitrate charge of the three isomers.

Hidden domain boundary dynamics toward crystalline perfection.

A central paradigm of nonequilibrium physics concerns the dynamics of heterogeneity and disorder, impacting processes ranging from the behavior of glasses to the emergent functionality of active matter. Understanding these complex mesoscopic systems requires probing the microscopic trajectories associated with irreversible processes, the role of fluctuations and entropy growth, and the timescales on which nonequilibrium responses are ultimately maintained. Approaches that illuminate these processes in model systems may enable a more general understanding of other heterogeneous nonequilibrium phenomena, and potentially define ultimate speed and energy cost limits for information processing technologies.

In van der Waals (vdW) architectures of transition metal dichalcogenides (TMDCs), the coupling between interlayer exciton and quantum degrees of freedom opens unprecedented opportunities for excitonic physics. Taking the MoSe homobilayer as representative, we identify that the interlayer registry defines the nature and dynamics of the lowest-energy interlayer exciton. The large layer polarization () is proved, which ensures the formation of layer-resolved interlayer excitons.

A D-Band Dual-Polarized High-Gain LTCC-Based Reflectarray Antenna Using SIW Magnetoelectric-Dipole Elements.

State Key Laboratory of Millimeter-Waves, School of Information Science and Engineering, Southeast University, Nanjing 210096, China.

This paper presents a D-band dual linear-polarized wideband high-gain reflectarray (RA) antenna using low-temperature co-fired-ceramic (LTCC) technology. The proposed element comprises a dual-polarized magnetoelectric (ME) dipole and a multilayer slot-coupling substrate-integrated waveguide (SIW) phase-delay structure, which are organized in accordance with the receiving/reradiating (R/R) principle. The coverage of phase shifts for both orthogonal polarizations is set to be greater than 360 degrees by varying the length of the phase-delay structure.
