A Quest for the Mechanism of Ultrahigh Resolution SEM Imaging
Advanced Science, Volume 13, Issue 17, 23 March 2026.Using Monte Carlo simulations with explicit definitions of SE1 and SE2 align with a cascade secondary electron production model, this work shows that the 3D nanostructure modulated SE2 emission enhances other than to reduce topographical contrast via a “miniature Faraday cup” effect.

Structure and performance analysis of binary differential stochastic process shift keying
Tongxin xuebao, 2014 A novel modulation and demodulation structure based on binary differential stochastic process shift keying (BDSPSK) is proposed.The theoretical bit error rates (BER) under the Gaussian and quasi-static Rayleigh fading chan-nels are derived,respectively ...

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

Improved model for multiple uncorrelated Rayleigh fading channels
Tongxin xuebao, 2007 An improved model for multiple uncorrelated Rayleigh channels was proposed.Compared with other models,this new model satisfied not only the stochastic characters of Rayleigh channel but also the uncorrelation between different fading channels.The ...

Flow Compensation Recovers Sensitivity Lost to Convection in Gradient‐Enhanced TOCSY NMR Experiments
Chemistry–Methods, Volume 6, Issue 3, March 2026.Gradient‐enhanced TOCSY techniques are an essential tool in the NMR spectroscopist's toolkit. However, in the presence of convection, signal intensities can be severely diminished, an issue that is particularly common when using cryoprobes. Here, we present an easily implemented TOCSY experiment that reverses signal loss due to convection and ...

Monitoring Zoo Elephant Rumble Activity Using Combined Seismic and Acoustic Data
Ecology and Evolution, Volume 16, Issue 3, March 2026.At the Opel‐Zoo in Germany, we studied elephant rumble activity by recording low‐frequency signals with seismic and infrasound sensors. We detected over 1350 rumbles within 4 weeks that show temporal patterns, demonstrating the benefits of combining both sensing methods.

Performance Analysis of CA‐Polar Code for 5G‐IoT Low Power Wide Area Networks
Internet Technology Letters, Volume 9, Issue 2, March/April 2026.ABSTRACT CRC‐Aided Polar (CA‐Polar) codes are the standardized channel coding scheme for control channels of 5G eMBB service class due to their capacity achieving performance. This work aims to assess the compatibility and scalability of CA‐Polar codes toward low power IoT applications coming under the domain of LPWAN.
