Enhanced AT8 immunopositive neuronal perikarya in Tg-FDD-Tau mice.

, 2013
Staining of a section of the neocortex of a 6 month old Tg-Tau mouse (A) and a Tg-FDD-Tau (B) mouse. A statistically significant difference in the number of AT8-positive neuronal perikarya is observed between Tg-FDD-Tau (2x) mice and single Tg-Tau (Tau ...

FDD Massive MIMO Without CSI Feedback

IEEE Transactions on Wireless Communications
Transmitter channel state information (CSIT) is indispensable for the spectral efficiency gains offered by massive multiple-input multiple-output (MIMO) systems. In a frequency-division-duplexing (FDD) massive MIMO system, CSIT is typically acquired through downlink channel estimation and user feedback, but as the number of antennas increases, the ...

Winter soil temperature varies with canopy cover in Siberian larch forests

Environmental Research Letters
In the Arctic, winter soil temperatures exert strong control over mean annual soil temperature and winter CO _2 emissions. In tundra ecosystems there is evidence that plant canopy influences on snow accumulation alter winter soil temperatures.
