Alternative Approaches to Bilateral Stellate Ganglion Block for Treatment of Refractory Ventricular Arrhythmia. [PDF]
Case Rep AnesthesiolIntroduction and Importance Patients with ventricular arrhythmias (VAs) refractory to medical treatment suffer high morbidity and mortality. The stellate ganglion block is an effective diagnostic and therapeutic tool for refractory VAs. Case Presentation After obtaining an informed consent, we describe a case of a 62‐year‐old female who suffered ...

Marine Benthic Community Assembly Is Taxonomically Stochastic but Functionally Deterministic in a Dynamic Coastal Sea. [PDF]
Ecol LettWe assessed the balance between deterministic and stochastic processes in macrozoobenthic community assembly across 1323 sites in the Dutch Wadden Sea. Species‐based patterns were largely stochastic, while trait‐based patterns were more environmentally driven, with little influence from hydrodynamic disturbance.

Climate Change and Aflatoxin B<sub>1</sub> in Agriculture Products: A Systematic Review. [PDF]
Food Sci NutrClimate change mainly involves increasing temperatures and concentrations of the greenhouse gas carbon dioxide. These changes increase the expression of genes for mycotoxin synthesis, including aflatoxin B1, in fungi. These stressors also lead to reduced plant defenses against fungal infections.

eLoran: Resilient Positioning, Navigation, and Timing Infrastructure in Maritime Areas
IEEE Access, 2020 Global navigation satellite system (GNSS) and localization technology have become highly compact and effective. Although GNSS has been proven to be vulnerable to jamming when the signal strength is weak, most vehicles rely on it for navigation.

Demodulation Method for Loran-C at Low SNR Based on Envelope Correlation–Phase Detection
Sensors, 2020 Loran-C is the most important backup and supplement system for the global navigation satellite system (GNSS). However, existing Loran-C demodulation methods are easily affected by noise and skywave interference (SWI).

Two algorithms of geodesic line length calculation considering elevation in eLoran systems
IET Radar, Sonar & Navigation, 2023 The existing LOng RAnge Naviating System stations are mostly used by marine users and are situated at offshore, low‐altitude locations. As a result, the impact of height on the system's positioning accuracy is usually ignored.
