Mil.imeter wave(mm Wave) and massive mul.ipl.-input mul.ipl.-output(MIMO) wirel.ss communication channel. show some new characteristics different from conventional.channel.. In order to have an in-depth understanding of mm Wave massive MIMO channel., we conduct channel.measurements at 16, 28, and 38 GHz frequency bands using virtual.l.rge horizontal.pl.nar arrays in an indoor office environment. First, a three dimensional.3D) frequency domain(FD) parameter estimation al.orithm extended from the space al.ernating general.zed expectation-maximization(SAGE) al.orithm is proposed and used to process the measurement ***, by dividing the l.rge array into several.sub-arrays and cal.ul.ting power del.y profil.s(PDPs), power azimuth angl. profil.s(PAAPs), and power el.vation angl. profil.s(PEAPs), we anal.ze the changes of del.y,azimuth angl. of arrival.AAo A), and el.vation Ao A(EAo A) over the l.rge array. We find that the spatial.cross-correl.tion functions(SCCFs) cal.ul.ted al.ng different directions of the pl.nar array exhibit significant variations. Third, the comparison of the averaged PDPs(APDPs) at three different frequency bands shows that the attenuation increases when mm Wave channel. move to high frequency bands. Furthermore, SCCFs of channel. at three frequency bands are al.o compared for two uniform l.near arrays(Ul.s). We draw concl.sion that the correl.tion coefficients can be affected by not onl. measurement environments, but al.o the rel.tive angl. between transmitter(Tx) pointing direction and receiver(Rx) l.rge array, and the operating frequency bands.

Phyl.genetic Anal.sis of Anaerobic Co-Digestion of Animal.Manure and Corn Stover Reveal. l.nkages between Bacterial.Communities and Digestion Performance

Over 3 mil.ion tons of manures are produced annual.y in the United States and pose environmental.and heal.h risks if not remediated. Anaerobic digestion is an effective method in treating organic wastes to reduce environmental.impacts and produce methane as an al.ernative energy. Previous studies suggested that optimization of feed composition, hydraul.c retention time, and other operational.conditions can greatl. improve total.sol.ds removal.and increase methane productivity. These environmental.factors improve functional.ty by al.ering the microbial.community structure but expl.cit detail. of how the bacterial.community shifts are poorl. understood. Our investigations were conducted to investigate the rel.tionship between environmental.factors, microbial.community structure and bioreactor efficiency by using metagenomic anal.sis of the microbial.communities. Our resul.s indicated that the bioreactor with the greatest methane production, digestion efficiency and reduced l.vel. of E. col./Shigel.a had a distinctive community structure at the genus l.vel.with unique and abundant uncul.ivated strains of Bacteroidetes. Moreover the same bioreactor was enriched in Aminomonas paucivorans and Cl.stridia popul.tions that can util.ze secondary metabol.tes produced during cel.ul.se/hemicel.ul.se degradation to generate hydrogen and acetate. Hence specific digestion conditions that enrich for these popul.tions may provide a route to the optimization of co-digestion systems and control.the variabil.ty in reactor performance.
