Forth is a language that, for most programmers, is like the back side of the Moon: they know it is there but have never laid eyes on it. Yet Forth is mature (about as old as Lisp or C); ubiquitous in everyday applications such as automated tellers, package tracking, airline reservations, telephone switching systems, and microcontrollers everywhere; and built into millions of personal computers ...

This paper presents an exploratory study about how savvy end users configure return points in mediated interactions with Web applications through WNH (Web Navigation Helper), a user agent that supports rephrasing, explanation, commentary and elaboration of interaction in scripted Web activities. The study is part of a long-term research on selfexpression through software programming. Savvy user...

Synapses are located throughout the often-elaborate dendritic tree of central neurons. Hebbian models of plasticity require temporal association between synaptic input and neuronal output to produce long-term potentiation of excitatory transmission. Recent studies have highlighted how active dendritic spiking mechanisms control this association. Here, we review new work showing that associative...

Many genetic algorithms GA have been applied to solve different NP-complete combinatorial optimization problems so far. The striking point of using GA refers to selecting a combination of appropriate patterns in crossover, mutation, and and so forth and fine tuning of some parameters such as crossover probability, mutation probability, and and so forth. One way to design a robust GA is to selec...

We present a method to efficiently compute Wasserstein gradient flows. Our approach is based on generalization of the back-and-forth (BFM) introduced in Jacobs and Léger [ Numer. Math. 146 (2020) 513–544.]. solve optimal transport problems. evolve flow by solving dual problem JKO scheme. In general, much better behaved than primal problem. This allows us run large scale flows simulations for cl...

This paper theoretically and empirically explores bargaining delay in tariff negotiations. By imposing a bargaining structure in an equilibrium trade framework, I derive many testable predictions of delay. I then take my model to the newly compiled GATT (Torquay) tariff negotiation data, which includes detailed (product-level) information of the timing and contents of countries’ (back-and-forth...
