Abstract: The present disclosure provides rechargeable divalent metal batteries comprising a multidentate compound. In particular, the presence of a multidentate compound in the electrolyte of the rechargeable divalent metal batteries significantly increases the interfacial charge transfer kinetics and/or suppresses undesired side reactions on both cathodes and metal anodes. It is believed that these effects are at least in part due to solvation sheath reorganization by the multidentate compound. Other aspects of the disclosure include methods for reducing a charge transfer overpotential and methods for increasing a charge transfer kinetics in rechargeable divalent metal batteries.

Abstract: A computer-implemented method for speech emotion recognition is provided. The computer-implemented method includes an emotion prediction corresponding to speech data that is generated based on the speech data and a speech emotion recognition model without bias.

The fairness-constrained adversarial network includes a domain classifier for bias classification and the speech emotion recognition model. The loss function used for training the fairness-constrained adversarial network is positively related to a Wasserstein distance (WD) loss.

Abstract: A low-power standard-compliant NB-IoT wake-up receiver (WRX) is presented. The WRX is designed as a companion radio to a full NB-IoT receiver, only operating during discontinuous RX modes (DRX and eDRX), which allows the full high-power radio to turn off while the wake-up receiver efficiently receives NB-IoT Wake-Up Signals (WUS). The fabricated receiver achieves 2.1 mW power at ?109 dBm sensitivity with 180 KHz bandwidth over the 750-960 MHz bands. The WRX is fabricated in 28 nm CMOS and consumes 5× less power than the best previously published traditional NB-IoT receivers. This disclosure is the first designed dedicated wake-up receiver for the NB-IoT protocol and demonstrates the benefits of utilizing a WRX to reduce power consumption of NB-IoT radios.
