The two dimensional Mazo limit [PDF]
Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005 Faster than Nyquist (FTN) signaling is extended. We send FTN pulse trains that overlap in both time and frequency; this is called two dimensional Mazo signaling. The minimum time and frequency separation that achieves dmin 2 = 2 for root raised cosine pulses is found. Two dimensional signaling is more bandwidth efficient than one dimensional.

Wound Healing and Angiogenic Profiling of Dermal Endothelial Cells Isolated From People With Type 2 Diabetes. [PDF]
FASEB JPrimary human dermal microvascular endothelial cells (HDMVECs) isolated from individuals with type 2 diabetes (T2D) exhibit dysregulated intrinsic properties, including altered morphology, reduced nitric oxide (NO) availability, and loss of endothelial identity.

Hexagonal Multicarrier Faster-Than-Nyquist Signaling
IEEE Access, 2017 Multicarrier faster-than-Nyquist (MFTN) signaling is a spectral efficient modulation scheme for future communication systems. In MFTN signaling, the intersymbol interference (ISI) and intercarrier interference (ICI) are introduced intentionally by the ...

Low-Complexity Detection of High-Order QAM Faster-Than-Nyquist Signaling
IEEE Access, 2017 Faster-than-Nyquist (FTN) signaling is a promising non-orthogonal transmission technique to considerably improve the spectral efficiency. This paper presents the first attempt in the literature to estimate the transmit data symbols of any high-order ...

Journal of Environmental Engineering and Landscape Management, 2011 Vehicles release large amounts of heavy metals to the environment. There have been done a lot of investigations analysing the distribution of heavy metals in soils near intensive regional roads. However, there is lack of investigations into the impact of
