Modularity in signaling systems [PDF]

open access: yesPhysical Biology, 2012
Modularity is a property by which the behavior of a system does not change upon interconnection. It is crucial for understanding the behavior of a complex system from the behavior of the composing subsystems. Whether modularity holds in biology is an intriguing and largely debated question.

Dissecting the impact of Frizzled receptors in Wnt/beta-catenin signaling of human mesenchymal stem cells [PDF]

open access: yes, 2012
Wnt/beta-catenin signaling is of fundamental importance in the regulation of self-renewal, migration/invasion, and differentiation of human mesenchymal stem cells (hMSCs).

A Systems Approach for Decoding Mitochondrial Retrograde Signaling Pathways

open access: yes, 2018
Mitochondrial dysfunctions activate retrograde signaling from mitochondria to the nucleus. To identify transcription factors and their associated pathways that underlie mitochondrial retrograde signaling, we performed gene expression profiling of the ...

How a Bacillus “Sees” the World: Information Needs and Signaling Resources of Mycobacterium Tuberculosis

open access: yestripleC: Communication, Capitalism & Critique, 2011
Any living cell parasitizing a host organism is immersed into a molecular environment of unfathomable complex- ity. For the advancement of its life cycle in such “hostile” a territory, the cell has to carefully sense its environment, “see” the ongoing ...

Compression System for the Phonocardiographic Signal [PDF]

open access: yes2007 International Conference on Field Programmable Logic and Applications, 2007
An FPGA-based approach is proposed for implementing a compression system developed specifically for the signal of phonocardiogram. The compression method offers better rate and distorsion than standard audio compression techniques. Both the algorithm and the details on the solutions adopted for its implementation are presented in this paper.

Three-Phase Diode-Clamped Four-Level PWM Inverter With Offset Voltage Injection

open access: yesIEEE Access
In this paper, a three-phase diode-clamped four-level PWM inverter with offset voltage injection is proposed. The proposed inverter is based on multi-neighboring reference vector (discontinuous) pulse-width modulation (MNRV (D)PWM), where multiple ...

A HOSPITAL SIGNAL SYSTEM. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1907
In October, 1904, I devised, for the Hospital of the Good Samaritan, a signal system for calling nurses to patients, which has the following advantages: Noiseless. There being no bells, the call is absolutely silent. Monitor board. This is in the office of the superintendent of nurses and enables this officer or her representatives to observe each ...
