FM jamming cancellation suppression based on noise floor estimation with dynamic threshold
MATEC Web of Conferences, 2017 Technique of FM jamming time domain cancellation suppression based on noise floor estimation with dynamic threshold is researched, by using the colored noise NLR filter estimation algorithm instead of the narrowband filtering algorithm, the problem that ...

Estimation of the distribution of the EMG signal amplitude
Acta Neurobiologiae Experimentalis, 1996 Quantitative analysis of electromyographic (EMG) data still demands new methods. One of the methods is based on counting occurrences of signal crossings of "noise level" (per time unit). This provides an estimator of the so called "aggregate activity." These data can be obtained by a spike trigger connected to a computer.

FEBS Open Bio, EarlyView.We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Amplitude estimating algorithm for single channel mixing signals
Tongxin xuebao, 2011 Aimed at non-cooperative communication situations an amplitude estimating question for single channel MSK mixing signals with the same modulating parameters was studied.Based on the derivation of cyclic spectrum for MSK mixture,amplitudes of mixing ...

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank
FEBS Open Bio, EarlyView.Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

Nonlinear control of unsteady finite-amplitude perturbations in the Blasius boundary-layer flow [PDF]
, 2013 The present work provides an optimal control strategy, based on the nonlinear Navier–Stokes equations, aimed at hampering the rapid growth of unsteady finite-amplitude perturbations in a Blasius boundary-layer flow.
