It is found that secondary ion and neutral spectra obtained under both bombardment conditions can be acquired in an interleaved manner throughout a single accelerator pulse cycle, thus making efficient use of valuable beam time.
This implies that demographic structure, such as that studied here, is difficult to detect with a classical measure of deviations from the standard neutral frequency spectrum.
This relaxation to the neutral haplotype spectrum is shown in Figure 2B.
We used patterns of polymorphism within each group to detect instances of selection causing departure from the neutral frequency spectrum.
Because a whole asexual genome forms a single linkage group, such background selection [ 31] is likely to produce a considerable distortion in the neutral frequency spectrum toward an excess of rare variants in all loci including neutral ones [ 30].

During this period, many of the energetic neutral atom spectra show a peak at 100 eV.
Observed helium neutral line spectra at working pressure 100 mbar, applied voltage 1,000 V and at frequency 34.5 kHz.
Looking beyond LTE Advanced, the introduction of service and technology neutral approaches to spectrum management is likely to increase the importance of rendezvous, as more diverse spectrum bands become available for use.
That is why Ofcom is calling for a new "technology neutral" approach to spectrum regulation.The current, more prescriptive approach had its greatest success with GSM, the second-generation wireless technology that was mandated as a Europe-wide standard in 1987.
After addition of slight excess of triethylamine (10 μl) to the neutral form, the spectrum reverts back to a reduced form (more than 95% of the initial values of curve 5 in Fig. 5).
