Fractal dimension computation with the Parzon window and its application in target detection

open access: yes, 2005
The automatic target detection under natural backgrounds is an important topic in the field of automatic target recognition. Fractal dimension is generally related to the roughness of the surface.

Dim Range-Spread Target Detection for Stepped-Frequency Radar Using a Bernoulli Extended Target Filter

open access: yesSensors
Stepped-frequency radar is an important high range resolution radar. It can achieve wide overall bandwidth with narrow instant bandwidth. When the signal-to-noise ratio is low, detection and tracking become challenging due to dense false alarms and the ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Target models and waveform design for detection in MIMO radar

open access: yes, 2014
In this paper, we propose a general target model for multiple-input multiple-output (MIMO) radar. Two types of targets are presented. For each type of target, we develop a corresponding optimum waveform designing method to optimize detection performance.

Improved Multispectral Target Detection Using Target-Specific Spectral Reconstruction

open access: yesRemote Sensing
Hyperspectral sensors provide high spectral resolution, enabling accurate material discrimination and effective target detection. However, their practical use is constrained by limited spatial resolution and high acquisition costs.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Target-Induced Cascade Amplification for Homogeneous Virus Detection

open access: yes, 2019
Detection of viruses with high sensitivity is critical for the prevention and treatment of the related disease. Two homogeneous target-induced cascade amplification methods were proposed for the detection of enterovirus 71 and coxsackievirus B3.
