Advanced Science, EarlyView.Reverse Weak Polarity‐Induced Ordered Layer Control strategy, optimizing the design of layered structures, has been successfully designed. By leveraging inhomogeneous field of units to replace isotropic fields of metal cations, polar layers realize controllable layer stacking via a “layer→linker→layer” polarity transfer.

Advanced Science, EarlyView.The effect of the structural arrangement of DIO and its analogs on ferroelectric phases is explored. Consequently, it is found that an asymmetrically fluorinated phenyl 4‐biphenylcaroboxylate skeleton is one of the favorable structural motifs for the emergence of enantiotropic ferroelectric liquid crystal phases.

MathematicsFTN signalling is an effective communication method that achieves a high spectral efficiency. However, employing a symbol rate faster than the Nyquist rate disrupts the orthogonality between symbols, leading to unavoidable inter-symbol interference (ISI).

Solving Self-Interference Issues in a Full-Duplex Radio Transceiver
Proceedings, 2019 Most wireless devices transmit and receive at different spectrum frequency bands. This approach is no longer optimal due to increasing electromagnetic exhaustion. Besides, interferenceamong all present and future working services should be negligible.

Novel Cancellation Techniques and Throughput Analysis for 6G Full-Duplex Wireless System
Space: Science & TechnologyRecent researches show that it is possible to achieve full-duplex system if the self-interference signal could be cancelled completely for 6G research. The majority of the overall self-interference cancellation is contributed by passive cancellation. The

On cancellation of correlated interference
Journal of «Almaz – Antey» Air and Space Defence Corporation, 2016 The article considers a problem of receiving the pulse signal mixed additively with correlated interference. It shows that a whitening transformation may be implemented via a non-linear device performing interference selection and subsequent cancellation. Reception quality is evaluated.

Farmers’ Protests in Germany: Media Coverage and Types of Bias
Agribusiness, EarlyView.ABSTRACT The German farmers’ protests of 2024 sparked widespread media coverage and public debate. Yet, media coverage was not always positive, reflecting the media's attention‐seeking and selective focus. Occurrences of farmers blocking media outlets reflected distrust in how their concerns were portrayed.
