IMMUNOLOGY: Ignition Without Transmission

Quenching and Propagation of Combustion without Ignition Temperature Cutoff

We study a reaction-diffusion equation in the cylinder Ω = R×T, with combustion-type reaction term without ignition temperature cutoff, and in the presence of a periodic flow. We show that if the reaction function decays as a power of T larger than three as T → 0 and the initial datum is small, then the flame is extinguished — the solution quenches. If, on the other hand, the power of decay is ...

Fault Location on Compensated Transmission Lines without Current Measurement

This paper presents a novel fault location method for series compensated transmission lines. It is established based on synchronized voltages sampling and Thevenin impedance from both ends of series compensated transmission line. The method is based on the use of phasor measurement units (PMU) technology which is aimed to be independent of current measurements, fault type, fault resistance, fau...

Establishing Communication Systems without Explicit Meaning Transmission

This paper investigates the development of experience-based meaning creation and explores the problem of establishing successful communication systems in a population of agents. The aim of the work is to investigate how such systems can develop, without reliance on phenomena not found in actual human language learning, such as the explicit transmission of meaning or the provision of reliable er...

Evolution of mutualistic symbiosis without vertical transmission.

Mutualistic symbioses are considered to evolve from parasitic relationships. Vertical transmission, defined as the direct transfer of infection from a parent organism to its progeny, has been suggested as a key factor causing reduction of symbiont virulence and evolution of mutualism. On the other hand, there are several mutualistic associations without vertical transmission, such as those betw...
