The influence of electric vehicle charging stations on power grid harmonics is becoming increasingly significant as their presence continues to grow. This paper studies the operational principles of the charging current in the continuous and discontinuous modes for a three-phase uncontrolled rectification charger with a passive power factor correction link, which is affected by the charging pow...

In this letter, we consider a wireless uplink transmission scenario in which an unmanned aerial vehicle (UAV) serves as base station collecting data from ground users. To optimize the expected sum transmit rate without any prior knowledge of users (e.g., locations, channel state information and power), trajectory planning problem is optimized via quantum-inspired reinforcement learning (QiRL) a...

background: amplification of her2 is seen in 20-30% of breast cancer cases. measurement of her2 gene amplification appears to be of vital importance in planning the treatment schedule for patients with breast carcinoma. the aim of our study was to evaluate her2 amplification status in malignant and benign breast tumors by differential pcr (dpcr). materials and methods: the genomic dna was extra...

Analogous to metagenomics, environmental transcriptomics (metatranscriptomics) retrieves and sequences environmental mRNAs from a microbial assemblage without prior knowledge of what genes the community might be expressing. Thus it provides the most unbiased perspective on community gene expression in situ. Environmental transcriptomics protocols are technically difficult since prokaryotic mRNA...

background and objectives: loop-mediated isothermal amplification is a novel nucleic acid amplification assay providing as a simple diagnostic tool for rapid identification of microbial diseases in developing countries. in this study, a lamp assay was established for yersinia enterocolitica , a leading cause of acute enterocolitis in young children. materials and methods: lamp assay was establi...

using a new numerical model, the pump-to-signal relative intensity noise (rin) transfer in singlepumpfiber optical parametric amplifiers for low modulation frequencies is investigated. the model includesfiber loss, pump depletion, as well as the gain saturation, and therefore, it can describe the practicalcircumstances associated with various applications of fiber optical parametric amplifiers....

The performance of amplify-and-forward (AF) cooperative code-division multiple-access (CDMA) systems is analyzed over independent nonidentical (i.n.i.) Nakagami-m fading channels. In the underlying AF relaying scheme, each relay applies interference suppression to the received signal to mitigate the effect of multiple-access interference (MAI) where a soft estimate is obtained before signal amp...

The effects of using an multicarrier amplifier (MCPA) in the transmit chain of a cellular FDMA system utilizing switched multibeam base-station antennas is investigated. By combining several carriers prior to amplification, the signal envelope will be time varying and the MCPA will introduce non-linear distortion of the amplified waveforms. It is shown how the main beam direction and frequency ...

This paper extends our study on a multi-user receiver structure for base-station receivers with antenna arrays in multicellular systems. The receiver employs a beamforming structure with constraints that nulls the signal component in appropriate interference subspaces. Here we introduce a new mode, ISR-D (diversities), which finds and suppresses the subspace of the identified paths of all known...
