TL;DR: The vibrational densities of states in the lattice translation region below 130 cm −1 (3 THz) for structure I xenon hydrate and structure II krypton hydrates have been determined from incoherent inelastic neutron scattering experiments as mentioned in this paper.

TL;DR: On the upland site, the mature trees were more inbred, possibly due to the conditions under which regeneration occurred and because of weak selective pressure, while on the lowland site, clustering of similar genotypes was detectable on a local scale but the mature Trees were not inbred.
Abstract: Several hundred dominant and co-dominant individuals in two populations of black spruce, located within 2 km of each other and representing upland and lowland site types, were sampled and mapped. Multilocus isozyme genotypes were determined and the genetic organization of the two populations examined by means of nearest-neighbour analysis and spatial autocorrelation of alleles. On the upland site type, population density was much higher and variation in age considerably less than on the lowland site type, which was interpreted as evidence for fire origin in the former. On the upland site, the mature trees were more inbred, possibly due to the conditions under which regeneration occurred and because of weak selective pressure. On the lowland site, clustering of similar genotypes was detectable on a local scale but the mature trees were not inbred. The two populations were very similar in terms of allozyme frequencies.

TL;DR: In this article, the authors studied the aggregation of magnetic particles into chain-like structures in a cobalt-based magnetic fluid, exposed to external magnetic fields and observed a maximum correlation length of ∼65 nm equivalent to 3-4 particles up to highest magnetic fields.
Abstract: We studied the aggregation of magnetic particles into chain-like structures in a cobalt-based magnetic fluid, exposed to external magnetic fields. The length of chain segments in very strong magnetic fields of up to 2 Tesla was measured in situ using small angle neutron scattering. Arrangement of the magnetic particles was studied with the scattering vector aligned parallel to the magnetic field lines, and at angles of 30° and 60° with respect to . Although chains several hundred particles in length were predicted, we observe a maximum correlation length of ∼65 nm equivalent to 3–4 particles up to highest fields. We speculate that the interaction between chains, i.e., the interplay between the entropy and energy of the system combined with the particular properties of the magnetic dipole–dipole interaction ultimately decide the length of the particle chains.
