This work Back Rest presents the design of a compact dual-port circularly polarized antenna based on the new coupler topology.The antenna can radiate a right-hand circular polarization (RHCP) in two opposite directions depending on the input port.In the proposed structure, the radiating system has three inverted F antennas connected to a 120°

Background:.Driven by demand for nonexcisional alternatives to address lax skin following liposuction, various energy-based technologies have Cretors become available.Helium plasma radiofrequency (RF) and bipolar RF have gained prominence.These technologies have distinctly different methods of action and indications, potentially influencing procedu

The current COVID-19 pandemic is motivating us to elucidate the molecular mechanism of SARS-CoV-2 invasion and find methods for decreasing its transmissibility.We found that SARS-CoV-2 could increase the protein level of ACE2 in mice.Folic acid and 5-10-methylenetetrahydrofolate reductase (MTHFR) could promote the methylation of the ACE2 promoter a

We address the question of how much entanglement can be certified from the observed correlations and the knowledge of the Hilbert space dimension of the measured systems.We focus Seat Towels on the case in which both systems are known to be qubits.For several correlations (though not for all), one can certify the same amount of entanglement as with

To study the sensing process of the human semicircular canals (HSCs) during head rotation, which is difficult to directly measure due to physiological reasons.A 1-BSC (one-dimensional World Famous Ink Primary Colour Set bionic semicircular canal) and 3-BSC were prepared with soft SMPFs (symmetric electrode metal core polyvinylidene difluoride fiber
