Transitions between steady dynamical regimes in diverse applications are often modelled using discontinuities, but doing so introduces problems of uniqueness. No matter how quickly a transition occurs, its inner workings can affect the dynamics of the system significantly. Here we discuss the way transitions can be reduced to discontinuities without trivializing them, by preserving so-called hi...
In two famous and popular puzzles a participant is required to compare two numbers of which she is shown only one. We show that there is one simple principle behind these puzzles. In particular this principle sheds new light on the paradoxical nature of the first puzzle. According to this principle the ranking of several random variables must depend on at least one of them, except for the trivi...
[1] The shoaling of the nonlinear internal tide in Massachusetts Bay is studied with a fully nonlinear and nonhydrostatic model. The results are compared with current and temperature observations obtained during the August 1998 Massachusetts Bay Internal Wave Experiment and observations from a shorter experiment which took place in September 2001. The model shows how the approaching nonlinear u...
This report summarizes the proceedings of the second workshop of the 'Minimum Information for Biological and Biomedical Investigations' (MIBBI) consortium held on Dec 1-2, 2010 in Rüdesheim, Germany through the sponsorship of the Beilstein-Institute. MIBBI is an umbrella organization uniting communities developing Minimum Information (MI) checklists to standardize the description of data sets, ...
The purpose of this paper is to implement theoretically, the observation that the relative importance of fundamental versus technical analysis in the foreign exchange market depends on the time horizon in currency trade. For shorter time horizons, more weight is placed on technical analysis, while more weight is placed on fundamental analysis for longer horizons. The theoretical framework is th...
Relativistic outflows (mainly observed in the radio) are a characteristic feature of both Galactic stellar mass black holes and supermassive black holes (SMBHs). Simultaneous radio and X-ray observations of Galactic sources have shown that the outflow is strong at low accretion rates, but it weakens dramatically or disappears completely at high accretion rates, manifesting structural changes in...
one of the ways to be informed on the extent of activities in various industries is to measure the rate of nominal protection. this paper tries to calculate the nominal and effective protection in order to examine the exchange rate unification impacts on the protection of pulp and paper industries with the aim of performing the exchange rate unification policy. therefore, nominal protection rat...
The distinctive switching spikes seen in single memristors are suppressed in networks of memristors. Instead oscillatory behaviour interrrupted by spontaneous irregular bursting spike patterns are seen. An investigation of two and three memrisor circuits was undertaken to elucidate the origin of these rich dynamics. No spiking is seen in circuits where all the memristors face the same way. Spik...
Building on the extensive cognitive science literature on the subject, this paper introduces a model of the brain mechanisms underlying social interactions in humans and other primates. The fundamental components of the model are the “Action Observation” and “Action Planning” Systems, dedicated respectively to interpreting/recognizing the partner’s movements and to plan actions suited to achiev...
The basic principle of in situ leaching is chemical mining. process to inject solution into the ore body, and spread pores mountain. completed by coupling action liquid seepage field ion exchange reactions. In production process, only one injection can be carried out a certain stope, so it impossible improve effect through practice. By simulating rare earth ions, this paper builds test stope tr...
