For the control, 20 min playback stimuli were created by merging two randomly selected 10 min recordings of background noise.
To habituate the meerkats to the playback, a randomly selected 10 min recording of background noise was played back prior to the treatment, during which no data were recorded.
In EDTA-treated blood membrane-bound LPSb decreased after 60 min of incubation, reaching background levels after 240 min. In contrast, membrane-bound LPSb remained detectable in heparinized blood in a high proportion of the cells.
#min(x) is continuously adapted for each pixel separately based on an estimate of background dynamics (#min(x) is reduced in dynamic regions of the background and increased in static regions).
Upon arrival at the recovery room, a PCA-pump (GemStar®, Hospira Inc. Lake Forest, Illinois, USA) was connected to the popliteal catheter set up to deliver bolus doses of 10 mL ropivacaine 0.2%%, with a lock-out time of 15 min, no background infusion and a maximum of 30 mL per 4 h.
We conducted a greenhouse rhizobox experiment using spring wheat (Triticum aestivum L). to investigate the effect of background N min (0, 5, 20 and 60 mg N kg−1) on root growth around a 1 g NH4 + N depot.
Following 10 min of photopic adaptation (30 cd/m2 background), cone-driven intensity responses were studied, using single flashes with intensities ranging from −1.6 to 2.9 log cds/m2 along 11 steps of incremental intensities.
Recording sessions started with 5 min of adaptation to the background, followed over 35 min with presentation of multiple stimulus pairs with pseudorandomized order for test and reference stimuli.
During this second experiment, EC was raised to 88 µS/cm after 5 min, which is above the range of background EC (µ = 85.57 µS/cm; σ = 0.52).
In order to adapt #min(x) according to background dynamics, a measure of background dynamics is needed.
