Latency (i.e. time delay) in electronic markets affects the efficacy of liquidity taking strategies. During liquidity, takers process information and send marketable limit orders (MLOs) to exchange, order book (LOB) might undergo updates, so there is no guarantee that MLOs are filled. We develop a latency-optimal trading strategy improves marksmanship takers. The interaction between LOB modeled...

The decline of aging C. elegans male's mating behavior is correlated with the increased excitability of the cholinergic circuitry that executes copulation. In this study, we show that the mating circuits' functional durability depends on the metabolic regulator SIR-2.1, a NAD(+)-dependent histone deacetylase. Aging sir-2.1(0) males display accelerated mating behavior decline due to premature hy...
