Sepsis is a modern medicine icon and the onset of organ dysfunction is one of the worst scenario. More than 100 distinct molecules have been proposed as useful biological markers of sepsis. TNF-alpha, IL-6, chemokines and cytokines are considered the first line factors able to drive the dynamic process of sepsis. The PIRO scheme is a new classification of different aspects, used to stage sepsis...

 Abstract—A Solid state calibration noise source for precision radio astronomy receivers has been designed built and tested. The Noise source has flat output noise spectrum, stability in time and frequency (smooth response), very low power dissipation, excellent power match...all on a very compact package that can easily be integrated with a radio astronomy receiver. The noise source has an in...

Singular Spectrum Analysis (SSA) is a powerful data decomposition/recompostion technique that can be used to reduce the noise in time series. Compared to existing solutions aiming at similar purposes, such as frequency-based filtering, it benefits from easier-to-exploit intuitions, applicability in contexts where low sampling rates make standard frequency analyses challenging, and the (theoreti...

background and objectives: the present work was carried out to investigate the ability of spirulina platensis to produce antimicrobial substance against bacteria and fungi.  materials and methods: the cells of the cyanobacterium were subjected to different extractions and the purified antagonistic compound proved to be effective against broad spectrum of bacteria and fungi. the antagonistic com...

Given a general source V = {V n } ∞ n=1 with countably infinite source alphabet and a general channel W = {W n } ∞ n=1 with arbitrary abstract channel input/channel output alphabets, we study the joint source-channel coding problem from the information-spectrum point of view. First, we generalize Feinstein's lemma (direct part) and Verdú-Han's lemma (converse part) so as to be applicable to the...

This paper clarifies a necessary condition and a sufficient condition for transmissibility for a given set of general sources and a given general broadcast channel. The approach is based on the informationspectrum methods introduced by Han and Verdú. Moreover, we consider the capacity region of the general broadcast channel with arbitrarily fixed error probabilities if we send independent priva...

This paper considers the use of an all-fiber Mach–Zehnder interferometer (MZI) to equalize the output spectrum of a super-luminescent light emitted diode (SLED). A minimax approach and a window integration approach are proposed to design spectrum equalization filters with pre-specified performance indices. To present the proposed design approaches, a single stage MZI is used as an illustrative ...

Separating audio mixtures into individual tracks has been a long standing challenging task. We introduce a novel unsupervised audio source separation approach based on deep adversarial learning. Specifically, our loss function adopts the Wasserstein distance which directly measures the distribution distance between the separated sources and the real sources for each individual source. Moreover,...

A psychoacoustic model of the source spectrum has been proposed in which four spectral slope parameters describe perception of overall voice quality: H1-H2 (the difference in amplitude between the first and second harmonics), H2-H4, H4-2000 Hz (i.e., the harmonic nearest 2000 Hz), and 2000-5000 Hz. The goals of this study are to evaluate perceptual sensitivity in the mid-to-high frequency range...

Given a general source V = fV gn=1 with countably in nite source alphabet and a general channel W = fW ng1 n=1 with arbitrary abstract channel input and output alphabets, we study the joint source-channel coding problem from the information-spectrum point of view. First, we generalize Feinstein's lemma (direct part) and Verd u-Han's lemma (converse part) so as to be applicable to the general jo...
