In multiple target tracking with radar, weak target measurements are often hard to observe due to masking by sidelobes of measurements from stronger targets. The result is lost tracks and deteriorated joint tracking performance. In this work, we design configurable waveforms and adjust the positioning of their ambiguity function (AF) sidelobes to unmask weak targets and improve tracking perform...

The autonomous activation function-2 (AF-2) in the mineralocorticoid receptor (MR) E/F domain is known to play a major role in the ligand-induced transactivation function of MR; however, it remained unclear about the transactivation function of its A/B domain. We therefore tried to characterize the MR A/B domain as the AF-1 and further studied the actions of known coactivators for AF-2 in the E...

l.n this paper, the performances of constant falsealarm rate (CFAR) burst detection schemes are analyzed and compared for a communication system which employs constant modulus modulation format and a typical time division multiple access (TDMA) protocol, The burst detection probabilities are derived to incorporate the received signal quality measure which can be expressed as a function of cross...

The uniqueness theorem for ambiguity functions states that if waveforms u(f) and u(f) have the same ambiguity function, i.e., X%(‘S, A) = X.(‘S, A), then u(f) and u(f) are identical except for a rotation, i.e., u(f) = e%(f), where ;i is a real constant. Through the artifice of treating the even and odd parts of the waveforms, denoted e(f) and o(f), respectively, correlative results have been ob...

In this contribution we consider the popular widelaning technique from the viewpoint of ambiguity decorrelation. It enables us to cast the technique into the framework of the least-squares ambiguity decorrelation adjustment (LAMBDA) and to analyse its relative merits. In doing so, we will provide answers to the following three questions. Does the widelane decorrelate? Does it explicitly appear ...

I have read the article entitled “Cognitive function and adherence to anticoagulation treatment in patients with atrial fibrillation” by Jankowska-Polańska, et al., with great interest. The investigators reported that cognitive impairment is an independent determinant of compliance with pharmacological therapy in elderly patients with atrial fibrillation (AF). Lower adherence, beyond the assess...

Atrial fibrillation (AF) is the most common cardiac arrhythmia with a potential to cause serious complications. Mitochondria play central roles in cardiomyocyte function and have been implicated in AF pathophysiology. MicroRNA (miR) are suggested to influence both mitochondrial function and the development of AF. Yet mitochondrial function and miR expression remain largely unexplored in human a...

Based on the finding that some transcription factors contain multiple transcriptional regulatory activities, we constructed a panel of rat androgen receptor (AR) mutants containing small internal deletions and point mutations within the amino-terminal region of the receptor. Trans-activation assays in CV-1 cells using AR-responsive reporter genes were performed and led to the identification of ...
