Modern time series are usually composed of multiple oscillatory components, with time-varying frequency and amplitude contaminated by noise. The signal processing mission is further challenged if each component has an pattern, or the wave-shape function, far from a sinusoidal pattern even changing to time. In practice, components exist, it desirable robustly decompose into for various purposes,...

Treatment of mouse lymphoma S49 cells with D,L-alpha-difluoromethylornithine (DFMO), an inhibitor of ornithine decarboxylase, depleted cellular polyamine levels and stopped cell growth. The cells were arrested predominantly in G1. Thus, polyamine depletion may lead to a regulatory growth arrest in S49 cells. We tested two hypotheses regarding the relationship of growth arrest mediated by polyam...

Cell senescence is increasingly recognized as a major contributor to the loss of health and fitness associated with aging. Senescent cells accumulate dysfunctional mitochondria; oxidative phosphorylation efficiency is decreased and reactive oxygen species production is increased. In this review we will discuss how the turnover of mitochondria (a term referred to as mitophagy) is perturbed in se...

The principle of compressed sensing (CS) can be applied in a cryptosystem by providing the notion of security. In this paper, we study the computational security of a CS-based cryptosystem that encrypts a plaintext with a partial unitary sensing matrix embedding a secret keystream. The keystream is obtained by a keystream generator of stream ciphers, where the initial seed becomes the secret ke...

BACKGROUND The severity of asthma varies between individuals and over time. As a result individuals may have marked variation in their need for asthma treatment. Adjustable dosing enables patients to assume greater involvement in managing their own condition. OBJECTIVE To compare the costs and effectiveness of fixed dosing of budesonide/formoterol (Symbicort Turbohaler) with adjustable mainte...
