A hybrid multi-mode narrow-frame antenna RF/Antenna Cable for WWAN/LTE metal-rimmed smartphone applications is proposed in this paper.The ground clearance is only 5 mm $ imes45$ mm, which is promising for narrow-frame smartphones.The metal rim with a small gap is connected to the system ground by three grounded patches.This proposed antenna

Yarn Disruptions lead to a rapid loss of thermal and magnetic energy and can cause large heat loads, mechanical forces, and the excitation of a beam of relativistic runaway electrons.The operation of tokamaks at high energy and plasma current requires the use of a mitigation system to limit such detrimental effects.Mitigation techniques rely mainly

The existence of the neutral section is used to be a major problem of the AC electrified railway.Although the conventional thyristor-based auto-passing Memory Foam Mattress neutral section schemes allow a train to go through the neutral section with power, there still exists a power interruption time in milliseconds and the issue of the inrush curr

The Yellow Sea is a strongly tidally-driven and highly stratified shallow sea due to the presence of the Yellow Sea Cold Water Masses.Observations show that the near-inertial event sustains for 10 days with a peak near-inertial velocity of 0.15m/s, which accounts Display Electronic Board for 30% of the total velocity during the passage of a cyclone

In the chemical and petrochemical industry, the primary focus for workers in the upcoming years is to develop innovative and secure technologies and equipment that comply with stringent quality standards.This imperative encompasses the production of materials, devices, and other products that meet the highest global benchmarks in technical and econ
