Blazing New Trails (Pollen Tube Guidance in Flowering Plants).
Higher “plants minimize their exposure to pollen from diverse species by precise regulation of flowering time, development of floral organs, and interactions with specific pollinators. These measures do not guarantee success, however, because of the vast quantities of pollen in the environment. Consequently, to ensure that only the appropriate sperm are delivered to the eggs, many plants have e...
متن کاملBlazing the trails before beating the path: Sample-efficient Monte-Carlo planning
You are a robot and you live in a Markov decision process (MDP) with a finite or an infinite number of transitions from state-action to next states. You got brains and so you plan before you act. Luckily, your roboparents equipped you with a generative model to do some Monte-Carlo planning. The world is waiting for you and you have no time to waste. You want your planning to be efficient. Sampl...
متن کاملBlazing Trails: Microquasars as Head-tail Sources and the Seeding of Magnetized Plasma into the Ism
We discuss the dynamics of microquasar jets in the interstellar medium, with specific focus on the effects of the X-ray binaries’ space velocity with respect to the local Galactic standard of rest. We argue that, during late stages in the evolution of large scale radio nebulae around microquasars, the ram pressure of the interstellar medium due to the microquasar’s space velocity becomes import...
متن کاملMinds of their own.
L ike a miniature Segway with eyes, a robot built from 3D printed plastic does laps around a cubicle here at Brain Corporation, having learned in a matter of minutes to avoid bumping into walls as it roams. As eyeRover scoots away, Peter O'Connor, a staff scientist at the robotics software company, steps into its route. Using a remote control unit, he briefly takes control of the foot-tall robo...
متن کاملIn Their Own Words
The author reviews three books written during the 1990s which rely on oral history to explore the lives of Japanese picture brides, refugees, and female Native elders. This article reveals how these three works succeed in using oral history to give voice to the individuals from these non-hegemonic groups that had been neglected by scholars in the past. It also explores some of the pitfalls that...
