Low complexity hybrid precoding algorithm for massive MIMO based on modified Newton method by Bo HU, Anding WANG, Guiyi WEI

“…A phase tracking algorithm was proposed for massivemultiple-input multiple-output(MIMO) systems based on the modified Newton (MN) method, which effectively reduced the high computational complexity in traditional high-performance hybrid precoding schemes.The algorithm optimized the analog precoding matrix from the perspective ofsub-dimensional vector recovery.In each sub-dimension optimization, the phase tracking method was used to transform the recovery of the analog precoding vectors into an unconstrained nonlinear optimization problem, which was then solved using the MN method.Concurrently, this strategy led to a marked reduction in the computational intricacy pertaining to both the computation of correction factors and the inversion of the Hessian matrix within the framework of the MN method.This was achieved through the insightful incorporation of Gerschgorin’s Disk theorem and the Hermitian matrix block-inverse lemma.Simulation results show that the proposed algorithm has higher spectral efficiency and lower computational complexity than several conventional high-performance hybrid precoding schemes.…”

Deranged aortic intima-media thickness, plasma triglycerides and granulopoiesis in Sl/Sld mice by Kottarappat N. Dileepan, Thomas P. Johnston, Yuai Li, Ossama Tawfik, Daniel J. Stechschulte

“…In comparison with normal littermates, Sl/Sld genotypes had elevated levels of plasma triglycerides with normal levels of plasma cholesterol, and the high-fat diet markedly lowered the triglyceride levels. Total peripheral blood leukocytes, the monocyte and granulocyte counts, and hemoglobin levels were significantly lower in Sl/Sld mice, although the number of lymphocytes, eosinophils and basophils were the same in both genotypes. …”

L’oppidum arverne de Gondole (Le Cendre, Puy-de-Dôme). Topographie de l’occupation protohistorique (La Tène D2) et fouille du quartier artisanal : un premier bilan by Yann Deberge, Ulysse Cabezuelo, Manon Cabanis, Sylvain Foucras, Magali Garcia, Katherine Gruel, Matthew Loughton, François Blondel, Pierre Caillat

“…Unlike her sister sites, Corent and Gergovie, detailed surveys of Gondole have only recently begun, mainly because Gondole lay undiscovered until the early 1990’s.The rescue archaeology trial trenching carried out between 2002 and 2005 led to the discovery of the famous horses and human burial, and marked the beginning of the archaeological research around this site. …”

Electronic Origin of Defect States in Fe-Doped LiNbO3 Ferroelectrics by Yuji Noguchi, Ryotaro Inoue, Masaru Miyayama

“…In contrast to Fe3+ on the Li site that forms the defect states (1e, a, and 2e) below the conduction band minimum, the reduction from Fe3+ to Fe2+ accompanied by a lattice relaxation markedly lowers only the a state (dz2) owing to a strong orbital hybridization with Nb-4d. …”
