SAR Waveform Diversity Using PN-Sequence and Its Optimization With Genetic Algorithm

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Waveform diversity is an important technique to suppress range ambiguities and extend the observation coverage of synthetic aperture radar (SAR) without sacrificing spatial resolution and power consumption.

Abnormal contextual modulation of visual contour detection in patients with schizophrenia.

PLoS ONE, 2013
Schizophrenia patients demonstrate perceptual deficits consistent with broad dysfunction in visual context processing. These include poor integration of segments forming visual contours, and reduced visual contrast effects (e.g.

Spontaneous phenotypic suppression of GacA-defective Vibrio fischeri is achieved via mutation of csrA and ihfA [PDF]

, 2015
Background: Symbiosis defective GacA-mutant derivatives of Vibrio fischeri are growth impaired thereby creating a selective advantage for growth-enhanced spontaneous suppressors. Suppressors were isolated and characterized for effects of the mutations on

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Functional antagonism between Sas3 and Gcn5 acetyltransferases and ISWI chromatin remodelers.

PLoS Genetics, 2012
Chromatin-modifying enzymes and ATP-dependent remodeling complexes have been intensely studied individually, yet how these activities are coordinated to ensure essential cell functions such as transcription, replication, and repair of damage is not well ...

Genetic variation in the HLA region is associated with susceptibility to herpes zoster. [PDF]

, 2015
Herpes zoster, commonly referred to as shingles, is caused by the varicella zoster virus (VZV). VZV initially manifests as chicken pox, most commonly in childhood, can remain asymptomatically latent in nerve tissues for many years and often re-emerges as

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

FEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Suppression of pattern-forming instabilities by genetic optimization

Physical Review E, 2016
We propose a versatile "stabilization on demand" method for the suppression of modulation instability in oscillatory spatially extended nonlinear systems, based on a genetically optimized multifrequency spatiotemporal modulation of the potential. The method, which ensures full stabilization even for very strong nonlinearities, forms a powerful tool ...
