One Novel Dynamic Routing and Wavelength Assignment Integrate Algorithm in WDM Optical Network

Li Lei,Tang Yong,Rao Min,Chen Yu,Jiang Jianfeng,Zhang Mingde,Sun Xiaohan

Strategic Study of CAE 2004, Volume 6, Issue 12,   Pages 73-77

Abstract:

Dynamic routing and wavelength assignment in the WDM networks with.both dynamic service traffic and limited-range wavelength conversion have been discussed. According to probability and limitation of wavelength conversion, a novel heuristic algorithm, which could achieve dynamic minimum cost routing and optimal virtual wavelength path, DMC - OVWP, is proposed based on Moone-Dijkstra algorithm. With separation and combination of routing and wavelength assignment subproblems, the algorithm optimizes RWA problem. The results simulating CERNET using the algorithm show that low blocking probability has been obtained.

Uncovering the effect of poly(ethylene-co-vinyl alcohol) molecular weight and vinyl alcohol content on

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 10,   Pages 1484-1502 doi: 10.1007/s11705-023-2331-y

Abstract: Various hydrophilic poly(ethylene-co-vinyl alcohol) (EVOH) were used herein to precisely control the structure and hydrodynamic properties of polysulfone (PSF) membranes. Particularly, to prepare pristine PSF and PSF/EVOH blends with increasing vinyl alcohol (VOH: 73%, 68%, 56%), the non-solvent-induced phase separation (NIPS) technique was used. Polyethylene glycol was used as a compatibilizer and as a porogen in N,N-dimethylacetamide. Rheological and ultrasonic separation kinetic measurements were also carried out to develop an ultrafiltration membrane mechanism. The extracted membrane properties and filtration capabilities were systematically compared to the proposed mechanism. Accordingly, the addition of EVOH led to an increase in the rheology of the dopes. The resulting membranes exhibited a microporous structure, while the finger-like structures became more evident with increasing VOH content. The PSF/EVOH behavior was changed from immediate to delayed segregation due to a change in the hydrodynamic kinetics. Interestingly, the PSF/EVOH32 membranes showed high hydrophilicity and achieved a pure water permeability of 264 L·m–2·h–1·bar–1, which was higher than that of pure PSF membranes (171 L·m–2·h–1·bar–1). In addition, PSF/EVOH32 rejected bovine serum albumin at a high rate (> 90%) and achieved a significant restoration of permeability. Finally, from the thermodynamic and hydrodynamic results, valuable insights into the selection of hydrophilic copolymers were provided to tailor the membrane structure while improving both the permeability and antifouling performance.

Removable Dyes—The Missing Link for In-Depth N-glycan Analysis via Multi-Method Approaches

Samanta Cajic,René Hennig,Valerian Grote,Udo Reichl,Erdmann Rapp,

Engineering doi: 10.1016/j.eng.2023.02.016

Abstract: As the roles of glycans in health and disease continue to be unraveled, it is becoming apparent that glycans’ immense complexity cannot be ignored. To fully delineate glycan structures, we developed an integrative approach combining a set of cost-effective, widespread, and easy-to-handle analytical methods. The key feature of our workflow is the exploitation of a removable fluorescent label—exemplified by 9-fluorenylmethyl chloroformate (Fmoc)—to bridge the gap between diverse glycoanalytical methods, especially multiplexed capillary gel electrophoresis with laser-induced fluorescence detection (xCGE-LIF) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Through the detailed structural analysis of selected, dauntingly complex N-glycans from chicken ovalbumin, horse serum, and bovine transferrin, we illustrate the capabilities of the presented strategy. Moreover, this approach “visualizes” N-glycans that have been difficult to identify thus far—such as the sulfated glycans on human immunoglobulin A—including minute changes in glycan structures, potentially providing useful new targets for biomarker discovery.
