Coupled Mutual Inhibition and Mutual Activation Motifs as Tools for Cell-Fate Control

Cells Tissues Organs, 2022
Multistability is central to biological systems. It plays a crucial role in adaptation, evolvability, and differentiation. The presence of positive feedback loops can enable multistability. The simplest of such feedback loops are (a) a mutual inhibition (MI) loop, (b) a mutual activation (MA) loop, and (c) self-activation.

Impact of Mutual Coupling on MIMO Channel Modelling

2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications, 2007
Mutual coupling effect between antennas on MIMO (multiple input multiple output) transmission is an important factor to take into account for an accurate modelling channel when antennas are closely spaced. The aim of this paper is to present the impact of mutual coupling on MIMO channel characteristics according to several propagation contexts.

Leaky and mutually coupled quantum wires

Physical Review B, 1993
In this paper, we investigate the effect on the transport in a quantum wire of short-ranged irregularities in the boundary. The results obtained are generalized to the case of a small hole in the boundary. Via such a hole, the wire is coupled to free two-dimensional space or to a second wire.

Applications of Mutually Coupled Reactor

IEEE Transactions on Power Apparatus and Systems, 1984
A new device of mutually coupled series reactor is proposed. Analytical and experimental studies on the working models by using the miniature system are conducted. Effects on improvement of stability limits, suppression of fault currents, minimization of shaft torsional responses of the turbine generators, and control of the power flow in a power ...

Transient Oscillations of Mutually Coupled Windings

Transactions of the American Institute of Electrical Engineers, 1932
IN THE PAST, the mathematical analysis of transient oscillations in transformer windings has been based upon a single winding having self and mutual inductances between its turns, capacitances along the stack and to ground, and, in one instance, resistances representing the losses.

Mutual coupling in phase array

2007 IEEE Antennas and Propagation Society International Symposium, 2007
Phase array systems can be found in military radar, satellite communications, space-time adaptive communications, and MIMO systems. As hardware capabilities increase, it will become feasible to implement MIMO communication systems, which will push further towards the Shannon Channel Capacity. This paper presents a comparison of standard beam formations,

Noise in Mutually Coupled Oscillators

9th European Microwave Conference, 1979, 1979
A general noise theory for microwave oscillators, which is based upon the describing function method, is developed and applied to the cases of mutually coupled and multiple-device oscillators. Explicit expressions are derived for the output power, the FM-and the AM-noise.

Synchronization of mutually coupled systems

Optics Communications, 2006
Abstract General operation conditions to obtain anticipated or retarded synchronization in a mutually coupled system with feedback are analyzed. Different from a unidirectionally coupled system, which type of synchronization will occur in a mutually coupled system does not solely depend on the difference between the feedback-delay time and the ...

Mutual coupling of shunt slots

IRE Transactions on Antennas and Propagation, 1960
Stevenson's method of analysis is extended to the case of a pair of shunt slots in the broad face of rectangular waveguide. The voltages in the slots are calculated including the effect of mutual coupling. Formulas suitable for calculation of mutual coupling are presented and the results of calculations for certain cases of overlapping quarter-wave ...

Transformation of Networks Containing Mutual Inductive Couplings into Equivalent Circuit Systems with No Mutual Couplings

IEEE Transactions on Power Apparatus and Systems, 1968
A general procedure for the transformation of networks containing mutual inductive couplings into equivalent circuit systems with no mutual couplings for which the ordinary resolution methods apply is illustrated. The proposals are made a) to provide a procedure for the prompt resolution of any problems?no matter how complex?concerning networks which ...
