An excessive sensing window fulfilling the PUs' protection requirement can produce a shortened transmission window which will limit CR-UWB's use of the overlapped spectrum.
These findings confirm that new protein is synthesized in response to high Cr concentration ([Cr]), which then acts to limit Cr uptake (P < 0.0001 by 2-way ANOVA).
This is also supported by a study in flies, which shows that the reduction in fatty acid oxidation limits CR-induced life span extension 31.
Extracellular reduction of Cr VI) to Cr III) therefore effectively limits chromium absorption.
For the samples collected in Piracicaba city, one sample presented highest concentrations for the majority of the elements when compared to the other four samples collected at the same place, exceeding the toxicity limits for: Cr, Ni, Cu, and Pb.
The restriction limits that CR nodes are only aware of its own location, as well as the directions of DCR users and LU.
In this case, the requested VBDC amount is limited: I f CR _ VBDC + PendingVbdcCounter ≥ VbdcMaxBackLog Then CR _ VBDC = VbdcMaxBackLog − PendingVbdcCounter (5).
In this case, the requested VBDC amount is limited: I f CR _ VBDC + PendingVbdcCounter ≥ VbdcMaxBackLog Then CR _ VBDC = VbdcMaxBackLog − PendingVbdcCounter (5) If capacity has to be requested (i.e., CR_VBDC > 0): ○ Apply granularities as specified in bandwidth granularity subsection below and update CR _VBDC value accordingly ○ Send VBDC request.
To exploit limited spectrum efficiently, CR technology allows unlicensed users to access licensed spectrum bands.
Regarding nonmeasurable lesions, the response was limited to either CR or non-PD due to difficulties in discrimination between incomplete response and SD.
Since the spectrum opportunities used for dynamic spectrum access in CR are limited in both time and space, CR has to be very fast and pragmatic in using the available spectrum bands.
