Pushing Hypercubes Around
We study collections of identical, connected modules which may relocate relative to each other; such a collection is called a modular metamorphic system (see [CPE], [MKK], [PEC], [RV], [YMK]). While such a system must always remain connected, it is possible for such a system to reconfigure its shape through successive motions of individual modules, either by rotation and sliding (e.g., [MKK]) o...
متن کاملChromatin: Pushing nucleosomes around
In a eukaryotic cell, genomic DNA does not exist in a free state, but is intricately complexed with chromosomal proteins, particularly histones. The basic chromatin fibre consists of an array of nucleosomes, each packaging around 200 base pairs (bp) of DNA; 146 bp is wound around a core of eight histone molecules (two each of H2A, H2B, H3 and H4), with the remaining DNA forming a linker to the ...
متن کاملSpiking Neural Controllers for Pushing Objects Around
We evolve spiking neural networks that implement a seekpush-release drive for a simple simulated agent interacting with objects. The evolved agents display minimally-cognitive behavior, by switching as a function of context between the three sub-behaviors and by being able to discriminate relative object size. The neural controllers have either static synapses or synapses featuring spike-timing...
متن کاملPushing estrogen receptor around in breast cancer.
The estrogen receptor-α (herein called ER) is a nuclear sex steroid receptor (SSR) that is expressed in approximately 75% of breast cancers. Therapies that modulate ER action have substantially improved the survival of patients with ER-positive breast cancer, but resistance to treatment still remains a major clinical problem. Treating resistant breast cancer requires co-targeting of ER and alte...
متن کاملPushing Avatars Around: A Mixed Reality Table Soccer Game
As virtual environments become more widely adopted for different tasks, it is critical that we develop techniques for designing spaces and interfaces that clearly suggest certain kinds of behavior for users, both in virtual and environments and for people who interact with a virtual environment through a mixed reality boundary. To explore these issues, we designed and deployed a mixed reality t...
