Gab signals for railway signaling
Journal of the A.I.E.E., 1927There is described in this paper a system of continuous signals operating within the cab of a railway locomotive. This system was developed in an effort to provide more reliable and safer signals than the common semaphore or light signals. The particular type of system is called the three-speed, continuous-control signal system.

Controlling Signals, Signal Propagation and Signal Transduction
2014When thousands and billions of cells have to fulfil the task to collectively construct an organism with its complex tissues and organs a manifold of mutual agreements are necessary. Controlling cells, for example organizing centres in early embryos, must emit coordinating signals. In order to respond to the signals cells must have the correct equipment

Reactive oxygen species (ROS) and reactive nitrogen species (RNS) have recently been shown to be involved in a multiplicity of physiological responses through modulation of signaling pathways. Some of the specific signaling components altered by reactive oxygen and nitrogen species (RONS) have begun to be identified.

Cancer develops when one or more cells begin to grow uncontrollably, presumably as a result of alterations in the highly regulated processes of normal cell division. These changes may result from germline or somatic mutations in genes that control normal cell proliferation, resulting in oncogenes.

The discovery of leptin was a major breakthrough in our understanding of the role of adipose tissue as a storage and secretory organ. Leptin was initially thought to act mainly to prevent obesity; however, studies have demonstrated profound effects of leptin in the response to fasting, regulation of neuroendocrine and immune systems, hematopoiesis ...

This review covers recent advances in gibberellin (GA) signaling. GA signaling is now understood to hinge on DELLA proteins. DELLAs negatively regulate GA response by activating the promoters of several genes including Xerico, which upregulates the abscisic acid pathway which is antagonistic to GA.

The purpose of this paper is to introduce a generalization of metric space that arises naturally out of the notion of signal function as it occurs, for example, in (5). In §§ 2-5, the basic definitions and motivation are given. In §§ 6 and 7 several elementary topological properties are proved, and in §§ 8 and 9 an important example from special ...

This chapter covers signals and signal processing. It presents a unified treatment of signals and interrupts, which helps put signals into a proper perspective. It treats signals as interrupts to processes, which diverts a process from its normal executions to do signal processing.
