TL;DR: In this paper, the authors studied the robustness of fusion frame systems and proposed a weighted and distributed processing technique for fusion frames, which is a natural fit to distributed processing systems such as sensor networks, but also an efficient scheme for parallel processing of very large frame systems.

TL;DR: The results indicate that, on average, animal population densities are positively correlated with area, which suggests that density compensation may be uncommon, and imply that the regional abundance and persistence of animal populations may depend strongly on the presence of a few large patches of suitable habitat, rather than on a regional network of small and large habitat patches.
Abstract: We compiled studies that report data on the relationship between animal population density and patch or island area for 287 individual species and 21 faunas. We tested the assumption of the equilibrium theory of island biogeography that population densities are independent of area by performing a meta-analysis using the linear correlation coefficient,r, as a measure of the effect of area on population density. We fit meta-analyses that used a random-effects model to these data to test for the effects of taxa, habitat, latitude, spatial scale, and overall population density. We also fit meta-analyses that used a fixed- effect model to the same data to estimate the repeatability of measurements of the correlation between population density and area within species. Contrary to the equilibrium theory of island biogeography, our results indicate that, on average, animal population densities are positively correlated with area, which suggests that density compensation may be uncommon. This result was found for individual species, but not for faunas. We found taxonomic differences in the correlation between population density and area, with insects and birds having on average large or moderately large positive correlations, respectively, and mammals having correlations near zero. Observations within individual species showed considerable repeatability. The observed overall positive cor- relation between the population density of individual animal species and area is best ex- plained in the context of the resource concentration hypothesis. Our results imply that the regional abundance and persistence of animal populations may depend strongly on the presence and continued persistence of a few large patches of suitable habitat, rather than on a regional network of small and large habitat patches.

TL;DR: In this paper, the authors examined the effect of governance structure on alliance performance and concluded that relational-based governance is more effective and influential in strengthening the interfirm partnership, stabilizing the alliance, and facilitating knowledge transfer between alliance partners.

TL;DR: In this article, the authors reported the detection of the lowest mass extrasolar planet yet found around a Sun-like star, a planet with an M sin i of only 14.21 ± 2.91 M in an extremely short period orbit (P = 2.808 days) around ρ1 Cancri, a planetary system that already has three known planets.
Abstract: We report the detection of the lowest mass extrasolar planet yet found around a Sun-like star—a planet with an M sin i of only 14.21 ± 2.91 M⊕ in an extremely short period orbit (P = 2.808 days) around ρ1 Cancri, a planetary system that already has three known planets. Velocities taken from late 2003-2004 at McDonald Observatory with the Hobby-Eberly Telescope revealed this inner planet at 0.04 AU. We estimate an inclination of the outer planet ρ1 Cancri d, based on Hubble Space Telescope Fine Guidance Sensor measurements that suggest an inner planet of only 17.7 ± 5.57 M⊕, if coplanarity is assumed for the system.

TL;DR: It is demonstrated that sinus mucosal health is highly dependent on the composition of the resident microbiota as well as both a new sino-pathogen and a strong bacterial candidate for therapeutic intervention, and the critical necessity for a replete mucosal microbiota to protect against this species.
Abstract: Persistent mucosal inflammation and microbial infection are characteristics of chronic rhinosinusitis (CRS). Mucosal microbiota dysbiosis is found in other chronic inflammatory diseases; however, the relationship between sinus microbiota composition and CRS is unknown. Using comparative microbiome profiling of a cohort of CRS patients and healthy subjects, we demonstrate that the sinus microbiota of CRS patients exhibits significantly reduced bacterial diversity compared with that of healthy controls. In our cohort of CRS patients, multiple, phylogenetically distinct lactic acid bacteria were depleted concomitant with an increase in the relative abundance of a single species, Corynebacterium tuberculostearicum. We recapitulated the conditions observed in our human cohort in a murine model and confirmed the pathogenic potential of C. tuberculostearicum and the critical necessity for a replete mucosal microbiota to protect against this species. Moreover, Lactobacillus sakei, which was identified from our comparative microbiome analyses as a potentially protective species, defended against C. tuberculostearicum sinus infection, even in the context of a depleted sinus bacterial community. These studies demonstrate that sinus mucosal health is highly dependent on the composition of the resident microbiota as well as identify both a new sino-pathogen and a strong bacterial candidate for therapeutic intervention.
