Effects of clustering heterogeneity on the spectral density of sparse networks.

We derive exact equations for the spectral density of sparse networks with an arbitrary distribution of the number of single edges and triangles per node. These equations enable a systematic investigation of the effects of clustering on the spectral properties of the network adjacency matrix. In the case of heterogeneous networks, we demonstrate that the spectral density becomes more symmetric as the fluctuations in the triangle-degree sequence increase.

Heights of maxillary sinus and piriform aperture are valuable in sex prediction: a cone beam computed tomography study.

Purpose: This study utilized cone-beam computed tomography images to assess the potential of maxillary sinus (MS) and piriform aperture (PA) measurements in sex prediction and to identify possible correlations between these structures and the MS ostium.

Methods: A total of 204 images were selected and divided into two groups: 102 for constructing and testing the formula, and 102 for validation. In each subgroup, the images were equally divided for 11 measurements by two examiners in the MS (height, width, length, and total width), PA (height and width), and maxillary ostium diameter.

A common form of dominant human IFNAR1 deficiency impairs IFN-α and -ω but not IFN-β-dependent immunity.

Autosomal recessive deficiency of the IFNAR1 or IFNAR2 chain of the human type I IFN receptor abolishes cellular responses to IFN-α, -β, and -ω, underlies severe viral diseases, and is globally very rare, except for IFNAR1 and IFNAR2 deficiency in Western Polynesia and the Arctic, respectively. We report 11 human IFNAR1 alleles, the products of which impair but do not abolish responses to IFN-α and -ω without affecting responses to IFN-β. Ten of these alleles are rare in all populations studied, but the remaining allele (P335del) is common in Southern China (minor allele frequency ≈2%).
