A major goal of the Cognitive Infocommunication approach is to develop applications in which human and artificial cognitive systems are made to work more effectively. A critical step in this process is improving our understanding of human–human interaction so that it may be modeled more closely. Our work addresses this task by examining the role of entrainment – the propensity of conversational...

Intracellular oscillators entrain to periodic signals by adjusting their phase and frequency. However, the low copy numbers of key molecular players make the dynamics of these oscillators intrinsically noisy, disrupting their oscillatory activity and entrainment response. Here, we use a combination of computational methods and experimental observations to reveal a functional distinction between...

Entrainment, aka accommodation or alignment, is the phenomenon by which conversational partners become more similar to each other in behavior. While there has been much work on some behaviors there has been little on entrainment in speech and even less on how Spoken Dialogue Systems which entrain to their users’ speech can be created. We present an architecture and algorithm for implementing ac...

Random networks of coupled phase oscillators, representing an approximation for systems of coupled limit-cycle oscillators, are considered. Entrainment of such networks by periodic external forcing applied to a subset of their elements is numerically and analytically investigated. For a large class of interaction functions, we find that the entrainment window with a tongue shape becomes exponen...

In golden-mantled ground squirrels, phase angles of entrainment of circadian locomotor activity to a fixed light-dark cycle differ markedly between subjective summer and winter. A change in ambient temperature affects entrainment only during subjective winter when it also produces pronounced effects on body temperature (Tb). It was previously proposed that variations in Tb are causally related ...

Context. Strong observational evidence indicates that all extragalactic jets associated with AGNs move at relativistic speed up to 100 pc 1 kpc scales from the nucleus. At larger distances, reflecting the Fanaroff-Riley radio source classification, we observe an abrupt deceleration in FR-I jets while relativistic motions persist up to Mpc scale in FR-II. Moreover, VLBI observations of some obje...

Climatic warming and permafrost thaw are predicted to increase Arctic riverbank erosion, threatening communities accelerating sediment, carbon nutrient cycling between rivers floodplains. Existing theory assumes that pore-ice sets erosion rates, but overpredicts observed rates by orders of magnitude. Here, we developed a simple model predicts more modest due sediment-entrainment limitation armo...

Characteristics of enstrophy generation and entrainment velocity at the turbulent non-turbulent interface of a temporally evolving wake are studied using Direct Numerical Simulations (DNS), starting from the time instance when the instabilities develop to a fully turbulent state. Results reveal the dominant role of viscous effects compared to the production of enstrophy at the interface at all ...
