Modulators of Notch signaling

Seminars in Cell & Developmental Biology, 1998
In addition to the core components of the Notch pathway, a number of proteins have been identified that exert positive or negative influences on Notch signaling. These include extracellular modulators, which may influence binding or activation of Notch by its ligands, cytoplasmic modulators, which presumably influence signal transduction steps after ...

Automatic Modulation Recognition for Secondary Modulated Signals

IEEE Wireless Communications Letters, 2021
Automatic modulation recognition (AMR) for secondary modulated signals, remains as a bottleneck, since both analog and digital modulation are adopted in one signal. To address this issue, we focus on the original signal spectrum and the 2nd order spectrum of the pre-demodulated signal, which imply modulation features.

Shaping and non-equiprobable signaling for intensity-modulated signals

IEEE GLOBECOM 1998 (Cat. NO. 98CH36250), 1999
Summary: The theory of shaping and nonequiprobable signaling, which has been developed for conventional electrical signals, must be modified to treat intensity-modulated (IM) signals. The authors show that for IM signals, the optimum shape of the constellation bounding region in \(N\)-dimensional (\(N\)-D) space is an \(N\)-D simplex. As \(N\to \infty\)

Protein modules and signalling networks

Nature, 1995
Communication between cells assumes particular importance in multicellular organisms. The growth, migration and differentiation of cells in the embryo, and their organization into specific tissues, depend on signals transmitted from one cell to another.

Signals and Modulation

2017
Satellite navigation relies on signals radiated by orbiting satellites and received by mobile satellite navigation receivers. This chapter addresses the fundamentals of such navigation signals and introduces the most important underlying concepts. It provides an introduction to radio frequency signals including the basics of electromagnetic waves ...

Role of ITAM signaling module in signal integration

Current Opinion in Immunology, 2012
Diverse cell types use a small number of evolutionarily conserved signaling modules to integrate external cues and elicit distinct functions. A question thus arises as to how does a receptor, which contains a single signaling module, produce distinct outcomes to diverse signals, particularly if such module is shared amongst a family of receptors ...

Identification of the modulation type of a signal

ICASSP '85. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
It is possible to recognize the modulation type of an unknown signal in noise by its envelope characteristics. A quantity found to be distinctive to a given modulation type is the ratio (R) of the variance of the envelope to the square of the mean of the envelope.

Death Receptors: Signaling and Modulation

Science, 1998
REVIEW Apoptosis is a cell suicide mechanism that enables metazoans to control cell number in tissues and to eliminate individual cells that threaten the animal's survival. Certain cells have unique sensors, termed death receptors, on their surface.
