Cancer Science, EarlyView.Our findings provide compelling evidence that the SOD2‐superoxide metabolic axis functions as a mitochondrial redox checkpoint that governs mitophagy and ultimately shapes TKI sensitivity. ABSTRACT Superoxide dismutase 2 (SOD2) has been implicated in head and neck squamous cell carcinoma (HNSCC), yet its mechanistic contribution in regulating tumor ...

Computer Communication Review, 2013
This paper presents the design and implementation of the first in-band full duplex WiFi radios that can simultaneously transmit and receive on the same channel using standard WiFi 802.11ac PHYs and achieves close to the theoretical doubling of throughput in all practical deployment scenarios. Our design uses a single antenna for simultaneous TX/RX (i.e.

Disclosed is an adaptive Finite Impulse Response ("FIR") filter speakerphone that provides improved echo cancelation by the inclusion of a tracking comb filter having nulls which change to track the voice portion of communications. The speakerphone also includes a pair of ambient noise recorders for recording both ambient background noise received from

Full-duplex (FD) communications with simultaneous transmission and reception on the same carrier have long been deemed a promising way to boost spectrum efficiency, but hindered by the techniques for self-interference cancellation (SIC). Recent breakthroughs in analog and digital signal processing yield the feasibility of over 100 dB SIC capability ...

Full-duplex relaying communication
2013 21st Signal Processing and Communications Applications Conference (SIU), 2013In this work, data signaling rates and error performances of half-duplex and full-duplex relaying/cooperative systems in flat fading channels are investigated in ideal and non-ideal self interference cancellation cases. A hybrid relaying system that is able to choose between full-duplex or half-duplex transmission according to the value of self ...

Full duplex wireless has drawn significant interest in the recent past due to the potential for doubling network capacity in the physical layer and offering numerous other benefits at higher layers. However, the implementation of integrated full duplex radios is fraught with several fundamental challenges.

IEEE Wireless Communications Letters, 2014
This letter proposes spatial modulated full duplex (SMFD), which applies spatial modulation to a point-to-point full-duplex communication system. The spatial modulation transmits its information bits by transmit antenna selection in addition to symbol modulation, whereas the full-duplex (FD) technique suppresses self-interference leaking from the ...

Enabling wireless full-duplex (from an AP) with multiple half-duplex (HD) clients is key to widespread adoption of full-duplex (FD) in commercial networks. However, enabling FD in such networks is fundamentally challenged by a new form of uplink-downlink interference (UDI), arising between HD clients operating simultaneously in the uplink and downlink ...
