Radio Frequency Interference Impact Assessment on Global Navigation Satellite Systems [PDF]
, 2009 The Institute for the Protection and Security of the Citizen of the EC Joint Research Centre (IPSC-JRC) has been mandated to perform a study on the Radio Frequency (RF) threat against telecommunications and ICT control systems. This study is divided into

IET Communications, Volume 20, Issue 1, January/December 2026.The proposed model includes a dual‐stream deep learning architecture which has a 1D convolutional neural network (CNN)‐based spectral encoder and a graph convolutional network (GCN)‐based spatial encoder for extracting the frequency‐domain and node‐topology features. Experimental analysis of the proposed model is performed using the Real‐World Wireless

Ibis, Volume 168, Issue 1, Page 245-258, January 2026.Waterbirds distributed in semi‐arid and arid regions seem to have adapted their behaviour to the availability and seasonality of wetlands, increasing their mobility range. The Marbled Duck Marmaronetta angustirostris is a threatened waterbird that shows trans‐Mediterranean movements but these are poorly known.

, 2019 マルチユーザ空間変調（SM: Spatial Modulation）では，SM信号の疎性を用いた圧縮センシングによるマルチユーザ検出が研究されているものの，受信機においてチャネル情報が完全に既知であるという条件の下で議論されている．実際には受信機側でチャネル情報を推定し，推定したチャネル情報を用いて復調処理を行う．推定したチャネル情報の精度は復調の精度に影響を及ぼすため，チャネル推定は重要なものであり考慮しなければならない． そこで本研究ではチャネル推定を ...

BioMed Research International, Volume 2026, Issue 1, 2026.Biofilm‐related infections significantly contribute to bacterial diseases, with estimates suggesting that at least 80% of such infections are associated with biofilms. These infections often involve opportunistic pathogens, which not only influence the type of infection but also impact the microenvironment by interacting with other polymicrobial ...

ChemistryOpen, Volume 14, Issue 12, December 2025.A regioselective synthesis of fused thiazoles was achieved via aza‐Michael cyclization of thiazolidinone derivatives with hydrazines or heteroaryl amines. Density functional theory, local reactivity indices, and molecular electrostatic potential mapping are used to explain selectivity.
