Yasushi Saka: Stirring a melting pot of math and morphogens
I n a developing embryo, seemingly identical cells are directed to different fates by the combination of signals they receive. When the signals come from morphogens—extracellular molecules that spread from a localized source—the effect on a cell depends on the amount of morpho-gen it receives, with cells closer to the source receiving a higher dose. The change in morphogen concentration across ...
متن کاملThe Distributed Arti cial Intelligence Melting Pot
Artiicial Intelligence (AI) has emphasized building \stand-alone systems" that can solve problems with minimal help from other systems (computer or human). These systems have traditionally been brittle, in the sense that they fail miserably when presented with problems even slightly outside of their limited range of expertise. The predominant AI answer to brittleness is to inject more knowledge...
متن کاملServing Up from the Internet Melting Pot
I draw from two studies of home network and internet use in Kenya and the United Kingdom (U.K.) to showcase how bandwidth and economic constraints shape internet usage patterns and perceptions. I suggest that increasing visibility of these constraints can improve internet experiences for within-home browsing and transnational communications.
متن کاملAssortment of GABAergic Plasticity in the Cortical Interneuron Melting Pot
Cortical structures of the adult mammalian brain are characterized by a spectacular diversity of inhibitory interneurons, which use GABA as neurotransmitter. GABAergic neurotransmission is fundamental for integrating and filtering incoming information and dictating postsynaptic neuronal spike timing, therefore providing a tight temporal code used by each neuron, or ensemble of neurons, to perfo...
متن کاملMelting Pot: Social Works and the Evolution of Population Attributes
This paper links the two nascent economic literatures on social networks and cultural assimilation by investigating the evolution of population attributes in a simple model where agents are influenced by their acquaintances. The main conclusion of the analysis is that attributes converge to a melting-pot equilibrium, where everyone is identical, provided the social network exhibits a sufficient...
