В данной статье предлагается взгляд на многозначность художественного текста через понятие бистабильности. Рассматриваются критерии бистабильности, а также структуры, которых она реализуется. Сформулированная концепция демонстрируется нескольких литературных примерах. This article offers a look at the polysemy of literary text through concept bistability. Criteria for bistability are considered...

We analyze three simple genetic circuits which involve transcriptional regulation and feedback: the autorepressor, the switch and the repressilator, that consist of one, two and three genes, respectively. Such systems are commonly simulated using rate equations, that account for the concentrations of the mRNAs and proteins produced by these genes. Rate equations are suitable when the concentrat...

BACKGROUND Bistability is a fundamental property in engineered and natural systems, conferring the ability to switch and retain states. Synthetic bistable switches in prokaryotes have mainly utilized transcriptional components in their construction. Using both transcriptional and enzymatic components, creating a hybrid system, allows for wider bistable parameter ranges in a circuit. RESULTS I...

The inherent bistability and picosecond time-scale switching of the resonant tunneling diode (RTD) provides an ideal element for the design of digital circuits and analog signal quantizers in the 10-100 GHz domain. New differential RTD-based circuits for quantizers and a first-order Sigma-Delta modulator capable of operating at 10 GHz and beyond are

Phase transitions of thermal systems and the laser threshold were first connected more than forty years ago. Despite nonequilibrium nature laser, Landau theory phase transitions, applied directly to Scully-Lamb model (SLLM), indicates that is a second-order transition, associated with $U(1)$ spontaneous symmetry breaking (SSB). To capture genuine transition SLLM (i.e., single-mode without satur...

We study matter-wave bistability in a spin-1 Bose-Einstein condensate dispersively coupled to a unidirectional ring cavity. A unique feature is that the population exchange among different modes of matter fields is accomplished via spin-exchange collisions. We show that the interplay between the atomic spin mixing and the cavity light field can lead to a strong matter-wave nonlinearity, making ...

We investigate the azimuthal dependence of the switching field strength for nematic liquid crystal bistability on patterned alignment layers to determine the validity of a switching theory proposed by Kim et al. [Appl. Phys. Lett. 78, 3055 (2001)] and to evaluate higher-order azimuthal anchoring coefficients. Director behavior during switching is described in detail for general azimuthal direct...
