In the trace reconstruction problem , an unknown source string x ∈ {0, 1} n is sent through a probabilistic deletion channel which independently deletes each bit with probability δ and concatenates surviving bits, yielding of . The to reconstruct given independent traces. This has received much attention in recent years both worst-case setting where may be arbitrary [DOS19, NP17, HHP18, HL20, C...

the aim of this research was to optimize bioremediation of seawater samples spiked with 1000 mg/l crude oil for removal of n-alkanes (c12h26 to c34h70). bioaugmentation experiments were performed at laboratory scale: each bioreactor contained 250 ml dispersed crude-oil-contaminated seawater, indigenous acclimatized microorganism and nitrogen and phosphorus at concentrations based on central com...
