A Statistical Shmoo for a Decision Feedback Equalizer (DFE)
IEEE Access, 2023 This article proposes a statistical shmoo for a Decision Feedback Equalizer (DFE). A statistical shmoo shows a Bit-Error Rate (BER) distribution of a system depending on conditions such as a threshold voltage and sampling time.

Femtosecond‐Laser‐Induced Physical Unclonable Random Maze Structure for Storage‐Free Encryption
Advanced Science, EarlyView.Femtosecond‐laser‐induced gold random maze structures serve as multimodal physical unclonable functions for storage‐free encryption. Their stochastic optical, electrical, and Raman responses are generated by plasmon‐assisted Marangoni formation and converted into AES‐compatible keys without permanent secret‐key storage, offering a portable route toward

Breeding switchgrass for reduced nitrogen demand
Grassland Research, EarlyView.Breeding has improved switchgrass biomass yield, but productivity is still heavily dependent on nitrogen fertilizer application. The genetic diversity needed to improve nitrogen use efficiency of switchgrass remains underused, mainly because of the slow and laborious breeding process, thus leaving the crop's high nitrogen demand as a major barrier to ...

On the Use of Gaussian Approximation in Analyzing the Performance of Optical Receivers
IEEE Photonics Journal, 2014 The analytical calculation of the bit error rate (BER) of digital optical receivers that employ avalanche photodiodes (APDs) is challenging due to 1) the stochastic nature of the avalanche photodiode's impulse-response function and 2) the presence of ...
