Comparison of the qCON and qNOX indices for the assessment of unconsciousness level and noxious stimulation response during surgery [PDF]

, 2016
The objective of this work is to compare the performances of two electroencephalogram based indices for detecting loss of consciousness and loss of response to nociceptive stimulation.

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

FEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

A High-Power SPDT Switch With Resonant Isolation Based on GaAs BiFET Technology for Sub-6-GHz Front-End Modules

IEEE Access
In this study, we present the design of a single-pole double-throw (SPDT) switch for Sub-6 GHz applications, implemented using a 500-nm GaAs BiFET process. To enhance power handling capability, multi-gate transistors are selectively employed.

A Radio Frequency Non-reciprocal Network Based on Switched Low-loss Acoustic Delay Lines

, 2018
This work demonstrates the first non-reciprocal network based on switched low-loss acoustic delay lines. A 21 dB non-reciprocal contrast between insertion loss (IL=6.7 dB) and isolation (28.3 dB) has been achieved over a fractional bandwidth of 8.8% at a

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Design of millimeter-wave bandpass filters with broad bandwidth in Si-based technology [PDF]

, 2019
In this paper, a novel design approach is proposed for on-chip bandpass filter (BPF) design with improved passband flatness and stopband suppression. The proposed approach simply uses a combination of meander-line structures with metal-insulator-metal ...
