Analysis on Smooth Handoff in NEMO Route Optimization Protocols

Abstract: With existing Network Mobility Basic Support (NEMO BS) protocol, entire transmissions are completely handled via Mobile Router (MR) to its home network on behalf of all Mobile Network nodes (MNNs) during movement among different networks. This concerns in enlarged length of route with higher delay and loss in best cases. Hence, in order to overcome these constraints, applying Smooth Handoff (SH) technique in Route Optimization (RO) for NEMO is an optimal solution. Consequently, the main aim of this paper is to offer a constructive analysis by doing analysis on some of the current approaches on soft handoff for RO in NEMO as well as discuss their strengths and weaknesses concerning delay and packet loss with some open issues

VIBRATIONAL CIRCULAR DICHROISM SPECTRA AND NORMAL MODE ANALYSES OF THF

Author Institution: Department of Chemistry, University of Illinois at ChicagoWe have measured the vibrational circular dichroism (VCD) spectrum of $3,4-d_{2}$-tetrahydrofuran ($d_{2}$-THF) using an FTIR spectrometer. These spectra were broad and weak compared to previously studied isotopically chiral molecules but reliable features could be identified for several mid-ir bands. To interpret these spectra, a new force field for THF was developed based on an ab initio calculated force field with $C_{2}$ symmetry. For comparison, force fields with $C_{s}$ and $C_{2v}$ symmetries were also calculated. The $C_{2}$ geometry is calculated to be lowest in energy, and that force field gives the best fit after scaling to the ir and Raman data we have re-obtained from five isotopomers. Calculated VCD spectra obtained using Stephen's a priori model agree with experiment for many but not all modes. Fixed partial charge results are worse

The hydrogen sulfide-releasing compounds "ATB-346 and Diallyltrisulfide" attenuate Streptozotocin induced cognitive impairment, neuro-inflammation and oxidative stress in rats: involvement of Asymmetric dimethylarginine

Hydrogen sulfide (H2S) has attracted interest as a gaseous mediator involved in diverse processes in the nervous system, particularly with respect to learning and memory. However, its therapeutic potential in Alzheimer disease (AD) is not fully explored. Therefore, the effect of H2S-releasing compounds against AD like behavioural and biochemical abnormalities was investigated. Memory deficit was induced by intracerberoventicular injection of Streptozotocin (STZ, 3mg/kg). Animals were randomly assigned into 5 groups (12 rats each): normal control, STZ and 3 drug treated groups receiving Naproxen, H2S-releasing naproxen (ATB-346), and Diallyltrisulfide in 20, 32, 40 mg/kg/day, respectively. Memory function was assessed by passive avoidance and T-maze tasks. After 21 days, hippocampal IL-6, malondialdehyde, reduced glutathione (GSH), Asymmetric dimethylarginine (ADMA), and acetylcholinestrase activity were determined. ATB-346 and Diallyltrisulfide ameliorated behavioural performance and reduced malondialdehyde, ADMA and acetylcholinestrase activity while increased GSH. This study demonstrates the beneficial effects of H2S release in STZ-induced memory impairment by modulation of neuro-inflammation, oxidative stress and cholinergic function. It also delineates the implication of ADMA to the cognitive impairment induced by STZ. These findings draw the attention to H2S-releasing compounds as new candidates for treating neurodegenerative disorders which have prominent oxidative and inflammatory components as AD.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

A G3 Study of the Structure of Carbon-Nitrogen Nanoclusters

International audiencePossible structures of the carbon-nitrogen clusters of the form C(m)N(n) (m = 1-4, n = 1-4, m + n = 2-5) were predicted for the neutral, anion, and cation species in the singlet, doublet, and triplet states, whenever appropriate. The calculations were performed at the G3, MP2(fc)/6-311 + G*, and B3LYP/6-311+G* levels of theory. Several molecular properties related to the experimental data-such as the electronic energy, equilibrium geometry, binding energy, HOMO-LUMO gap (HLG), and spin contamination -were calculated. In addition the vertical electron attachment, the adiabatic electron affinity, and vertical ionization energy, of the neutral clusters were calculated. Most of the predicted lowest energy structures were linear, whereas bent structures became more stable with the increase of the cluster size and increase of the number of the N atoms. In most of the predicted lowest energy structures, the N atom prefers the terminal position with acetylenic bond. The calculated BE of the predicted clusters increases with the increase of the cluster size for the neutral and cation clusters but decreases with the increase of the cluster size for the anion clusters. The predicted clusters are characterized by high HLG of about 11 eV on the average, with that of the anion clusters is smaller than that for the neutral and cation clusters. It is concluded then that the anion clusters are less stable than the corresponding neutral and cation clusters. Finally, the N(2) loss reaction is treated
