In this paper, we propose and analyze DMAP-FR, a mobility and service management scheme with failure recovery (FR) control in Mobile IPv6 systems. The basic idea behind DMAP-FR is to leverage access routers (ARs) running as regional mobility anchor points (MAPs) as in Hierarchical Mobile IPv6 (HMIPv6) for mobility and service management formobile nodes (MNs). However, unlikeHMIPv6,DMAP-FR allow...
Vegetation stands have a heterogeneous distribution of light quality, including the red/far-red light ratio (R/FR) that informs plants about proximity of neighbors. Adequate responses to changes in R/FR are important for competitive success. How the detection and response to R/FR are spatially linked and how this spatial coordination between detection and response affects plant performance rema...
Individuals with low back pain (LBP) commonly present with an impaired flexion-relaxation (FR) response, characterised as continued lumbar muscle activation at maximal voluntary flexion. The aim of the present investigation was to explore the effectiveness of a surface electromyographic assisted stretching (SEMGAS) programme in improving FR. Nine volunteers with chronic LBP and an impaired FR t...
Aminoceramide mimetic was synthesized and conjugated to N-linked oligosaccharides having multivalent GlcNAc by reductive amination. Ceramide mimetic conjugates with "complex-type" glycan having five or six GlcNAc termini (termed Os Fr. B-Cer) were purified, analyzed by thin-layer chromatography (TLC), and finally characterized by MS/MS analysis through liquid chromatography/mass spectrometry. B...
Establishment of a nitrogen-fixing symbiosis between legumes and rhizobia not only requires sufficient photosynthate, but also the sensing of the ratio of red to far red (R/FR) light. Here, we show that R/FR light sensing also positively influences the arbuscular mycorrhizal (AM) symbiosis of a legume and a non-legume through jasmonic acid (JA) and strigolactone (SL) signaling. The level of AM ...
Phytochromes are plant photoreceptors that regulate plant growth and development with respect to the light environment. Following the initial light-perception event, the phytochromes initiate a signal-transduction process that eventually results in alterations in cellular behavior, including gene expression. Here we describe the molecular cloning and functional characterization of Arabidopsis F...
Using various photostationary state light sources to obtain reproducible phytochrome conversion of from 5 to 88% P(FR), assayed by 2 wavelength in vivo spectrophotometry, relationships between initial percent P(FR) and elongation of apical Avena coleoptile segments over the succeeding 20 hours in darkness were studied. With material grown in total darkness, all P(FR) levels promote elongation, ...
