Current discussions of offspring begging typically assume either that it is a signal directed at parents or that it represents a form of scramble competition to gain access to them. However, offspring might also display to inform nest mates that they will contest the next food item to be delivered; in other words, begging (possibly in the absence of parents) might serve purely as a form of nego...

The extreme downsizing effect on 2D SCO nanoparticles resulted in a two-step hysteretic behavior and stability aqueous dispersions.

hysteretic dampers as the most practical passive control methods have improved the seismic performance of steel structures through energy dissipation induced by large inelastic deformations. among them in this paper, kbf (knee braced frames), a special form of braced frames having a diagonal brace connected to a knee element instead of beam-column joint, is investigated. in such systems, the kn...

the current study focuses on the experimental investigation of frp strengthening of rc portal frame subjected to combined vertical and horizontal loads. the main target of this research is to enhance the proposed structural properties that the rc portal frame had before the seismic occurrences by providing retrofitting of both columns and joints with more deformation capacity. the effect of var...

The combination of non-linear control and linear control proposed in [1] provides very fast transient response (voltage step from 1 V to 1.5 V in 2 μs). This non-linear control is based on hysteretic control of the Cout current. This system is very sensitive to effects like aging, temperature, input and output voltage variation, etc., that modify the switching frequency. This paper proposes a f...

In this paper, an operator-based nonlinear vibration control of a flexible arm experimental system using piezoelectric actuator with hysteresis is discussed. The piezoelectric actuator exhibits hysteretic effects in the output displacement responses, which can cause inaccuracy and undesirable oscillations, where Prandtl-Ishlinskii(PI) model is used to describe the hysteresis. In order to compen...

In this paper we examine the stability of silicon tip apices by using density functional theory (DFT) calculations. We find that some tip structures - modelled as small, simple clusters - show variations in stability during manipulation dependent on their orientation with respect to the sample surface. Moreover, we observe that unstable structures can be revealed by a characteristic hysteretic ...

Bistable and hysteretic switches, enabling cells to adopt multiple internal expression states in response to a single external input signal, have a pivotal impact on biological systems, ranging from cell-fate decisions to cell-cycle control. We have designed a synthetic hysteretic mammalian transcription network. A positive feedback loop, consisting of a transgene and transactivator (TA) cotran...

We present a framework for non-prioritised belief revision i.e., belief revision in which newly acquired information is not always fully accepted in which the result of revision is arrived at via a kind of negotiation between old information and new. We show how both ordinary par t ia l meet revision and Fermd and Hansson's selective revision can be captured in this framework, and also how it s...
