Phylogenetics and genomic variation of Hepatocystis isolated from shotgun sequencing of wild primate hosts. by Paige E Haffener, Helena D Hopson, Alejandra Herbert-Mainero, Anayansi Ramirez, Ellen M Leffler

“…Principle components analysis based on genotype likelihoods across all samples showed evidence for population structure by primate host species. Across the genome, windows of high SNP density revealed candidate hypervariable loci including Hepatocystis-specific gene families possibly involved in immune evasion and genes that may be involved in adaptation to their insect vector and hepatocyte invasion. …”

Beam steering flexible transparent metasurfaces based on multi-bit phase gradient variations by Meijia Guo, Penghui Xin, Haoyuan Sun, Hengfeng Li, Leonid F. Chernogor, Zhejun Jin, Tian Liu, Yu Zheng

“…The metasurface unit uses a modified C structure to form dual-resonant points to form a wide frequency band, and the PB phase satisfy the relationship between the rotation angle of the element and the double difference of the reflected phase, by encoding metasurface arrays, functions such as reducing linearly polarized radar cross sections (RCS) and steering circularly polarized beams can be achieved. …”

Numerical simulation of the electromagnetic fields variations under the formation of the fault rupture before earthquake by M. I. Shimelevitch, E. A. Obornev, I. S. Feldman, V. A. Novikov

“…A 2D geoelectric model of a heterogeneous geological medium has been developed taking into account the processes occurred in the geological subj ect of flexure type which transforms into an uplift-thrust structure as a result of deformations. The model is based on a hypothesis of the variation of electrical conductivity of geomaterials in the local area of the fault under subcritical stress-state conditions due to the geodynamical processes. …”
