The efficient operation of single-source, single-sink wireless networks is considered with the diversity-multiplexing gain tradeoff (DMT) as the measure of performance. Whereas in the case of a point-to-point MIMO channel the DMT is determined by the fading statistics, in the case of a network, the DMT is additionally, a function of the time schedule according to which the network is operated, ...

In this paper, we study different modulation techniques for visible light communication (VLC), taking illumination constraints into account. Two schemes are compared, namely pulse amplitude (PAM) and carrierless phase (CAP) modulation, through both simulations experimental measurements. The data link under is based on low-cost components comprising a white light-emitting diode (LED) silicon PIN...

Caldesmon, an inhibitory actin binding protein, binds to actin and inhibits actin-myosin interactions, whereas caldesmon phosphorylation reverses the inhibitory effect of caldesmon on actin-myosin interactions, potentially leading to enhanced contraction. The goal of this study was to investigate the cellular signaling pathway responsible for caldesmon phosphorylation, which is involved in the ...

[Dmt(1)]DALDA (H-Dmt-d-Arg-Phe-Lys-NH(2); Dmt = 2',6'-dimethyltyrosine) is a dermorphin analog that shows high affinity and selectivity for the mu opioid receptor. The intrathecal potency of [Dmt(1)]DALDA far exceeded its affinity at mu receptors and suggests that other mechanisms must be involved in its action in the spinal cord. The affinity and selectivity of [Dmt(1)]DALDA was determined usi...

Amplitude modulation can serve as a cue for segregating streams of sounds from different sources. Here we evaluate stream segregation in humans using ABA- sequences of sinusoidally amplitude modulated (SAM) tones. A and B represent SAM tones with the same carrier frequency (1000, 4000 Hz) and modulation depth (30, 100%). The modulation frequency of the A signals (f(modA)) was 30, 100 or 300 Hz,...

The discrete multitone @MT) modulation/demodulation scheme is the standard transmission technique in the application of asymmetric digital subscriber lines (ADSL). Although the DMT can achieve higher data rate compared with other modulation/ demodulation schemes, its computational complexity is too high for cost-efficient implementations. For example, it requires 512. point IFFUFIT as the modul...

We report on the synthesis and crystal structure of solvent-free coordination polymer CoII(2,5-DMT) (1) with 2,5-DMT ≡ 2,5-dimethoxyterephthalate which is isostructural to already reported MnII ZnII congeners (C2/c, Z = 4). In contrast, for M MgII, a MOF DMF-filled pores obtained, namely Mg2(2,5-DMT)2(DMF)2 (2) (P1¯, 2). Attempts remove these solvent molecules record gas sorption isotherm did n...
