COVID-19 is mainly associated with respiratory distress syndrome, but a subset of patients often present gastrointestinal (GI) symptoms. Imbalances gut microbiota have been previously linked to virus infection. Understanding how the gut-lung axis affects progression can provide novel framework for therapies and management. In this study, we examined (n = 47) compared it healthy controls 19). Using shotgun metagenomic sequencing, identified four microorganisms unique in patients, namely...
This article proposes a free-positioning omnidirectional wireless power transfer (WPT) system with reticulated planar transmitter, which enables multiple receivers to be powered simultaneously in arbitrary positions and orientations. The transmitter is equipped four interleaved overlapped meander coils, thus, three-dimensional (3-D) rotating magnetic field generated the designed excitation current. Therefore, only single-coil (such as loop-type coil) required realize WPT. According...
This article proposes a tripolar plane-type (TPT) transmitter enabling three-dimensional (3-D) omnidirectional wireless power transfer (WPT) for consumer electronics, such as mobile phones and tablet computers. The proposed TPT is 2-D plan-type structure, but it shows 3-D transmitting capability. structure consists of two crossed bipolar coils unipolar circular coil, the three are mutually decoupled naturally. By calculating magnetic field distribution generated by transmitter, can be...
The power interference is always inevitable in the simultaneous wireless and data transfer (SWPDT) system resulting lower signal to noise rate (SNR) may cause failure of communication. Besides, between bidirectional source also problem during full-duplex To solve these problems, this article, an improvement SNR for SWPDT with communication mode proposed. In channel, double-sided <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">LCCL</i>...
This article proposes an omnidirectional wireless power transfer system for powering up electronic devices inside a tubular structure, which has good received voltage stability (RVS) no matter how the receiving coil self-rotates on its own axis or revolves around <i>z</i>-axis. Three-phase coils are taken as transmitter at primary side, and circular works receiver secondary side. Based three-phase half-bridge inverter inductor capacitor capacitor-series (LCC-S) compensated topology,...
The data transmission is always necessary for wireless power transfer systems, and however, the interference between major problem full-duplex simultaneous (SWPDT) system.
