The interventions and outcomes in the ongoing COVID-19 pandemic are highly varied. disease both impose costs harm on society. Some with particularly high may only be implemented briefly. design of optimal policy requires consideration many intervention scenarios. In this paper we investigate timing that not sustainable for a long period. Specifically, look at impact single short-term non-repeat...

Harvest plays an important role in management decisions, from fisheries to pest control. Discrete-time models enable us explore the importance of timing including order events particular actions. We derive novel mechanistic featuring explicit within-season harvest and level. optimization level through optimal control these population models. With a fixed level, is taken as Then both are used co...

The present work investigates the performance and emission characteristics of hydrous methanol fuelled Homogeneous Charge Compression Ignition (HCCI) engine. In the present work a regular diesel engine has been modified to work as HCCI engine. Hydrous methanol is used with 15% water content in this HCCI engine and its performance and emission behavior is documented. A spark plug is used for ass...

Synaptic plasticity is widely considered to be a cellular mechanism underlying learning and memory. In this issue of Neuron, Gu and Yakel show that the precise timing of a single cholinergic pulse of activity can determine whether plasticity will occur at a glutamatergic synapse and confer long-term potentiation versus depression.

The spike-timing-dependent plasticity (STDP), a synaptic learning rule for encoding learning and memory, relies on relative timing of neuronal activity on either side of the synapse. GABAergic signaling has been shown to control neuronal excitability and consequently the spike timing, but whether GABAergic circuits rule the STDP remained unknown. Here we show that GABAergic signaling governs th...

he last decade has seen the development of iteratively decodable error-control codes of unprecedented power, whose large coding gains enable reliable communication at very low signal-to-noise ratio (SNR). A by-product of this trend is that timing recovery must be performed at an SNR lower than ever before. Conventional timing recovery ignores the presence of error-control coding and is thus doo...
