Quantification of in vivo short echo-time proton magnetic resonance spectra at 14.1 T using two different approaches of modelling the macromolecule spectrum

Rolf Gruetter, Lijing Xin, Cristina Ramona Cudalbu

Reliable quantification of the macromolecule signals in short echo-time H-1 MRS spectra is particularly important at high magnetic fields for an accurate quantification of metabolite concentrations (the neurochemical profile) due to effectively increased s ...

Synthesis of poly(PEGA) Bioconjugates using RAFT Polymerization

Emmanuelle Bays

Protein-polymer conjugates are widely used in biotechnology and medicine, and non-toxic polymers for bioconjugation would be advantageous for these applications. Herein, we reported the toxicity of polymers synthesized by two commonly employed controlled r ...

Molar mass, surface tension, and droplet growth kinetics of marine organics from measurements of CCN activity

Athanasios Nenes

The CCN-relevant properties and droplet growth kinetics are determined for marine organic matter isolated from seawater collected near the Georgia coast. The organic matter is substantially less CCN active than (NH4)2SO4, but droplet growth kinetics are si ...

CCN activity and droplet growth kinetics of fresh and aged monoterpene secondary organic aerosol

Athanasios Nenes, Spyros Pandis

The ability of secondary organic aerosol (SOA) produced from the ozonolysis of α-pinene and monoterpene mixtures (α-pinene, β-pinene, limonene and 3-carene) to become cloud droplets was investigated. A static CCN counter and a Scanning Mobility CCN Analyse ...

Composites and methods for their production

Yves Leterrier, John Christopher Plummer, Marlene Rodlert

Intercalates and exfoliates formed from layered materials and dendritic polymers are disclosed, together with the uses of these materials, e.g. in producing composite materials. The dispersion of layered materials in a dendritic polymer matrix (hyperbranch ...

Weighing wimps with kinks at colliders: invisible particle mass measurements from endpoints

We consider the application of endpoint techniques to the problem of mass determination for new particles produced at a hadron collider, where these particles decay to an invisible particle of unknown mass and one or more visible particles of known mass. W ...

Observation of a near-threshold enhancement in the e+e- →Λc+Λc- Cross section using initial-state radiation

Olivier Schneider, Mingkui Wang, Chao Wang, Tagir Aushev, Vladislav Balagura, Sun Hee Kim, Xiao Wang, Jing Li

We report a measurement of the exclusive e+e-→Λc+Λc- cross section as a function of center-of-mass energy near the Λc+Λc- threshold. A clear peak with a significance of 8.2σ is observed in the Λc+Λc- invariant mass distribution just above threshold. With a ...

Effective velocity for transport in heterogeneous compressible flows with mean drift

Assyr Abdulle

Solving transport equations in heterogeneous flows might give rise to scale dependent transport behavior with effective large scale transport parameters differing from those found on smaller scales. For incompressible velocity fields, homogenization method ...

Production of new charmoniumlike states in e+e-→J/ψD() D̄() at s 10.6GeV

Olivier Schneider, Chao Wang, Tagir Aushev, Vladislav Balagura, Xiao Wang

We report a study of the processes e+e-→J/ψD()D̄(). In J/ψDD̄ we observe a significant enhancement in the DD̄ invariant mass spectrum, which we interpret as a new charmoniumlike state and denote X(4160). The X(4160) parameters are M=(4156-20+25±15)Me ...

Asymmetrical flow field-flow fractionation coupled to multi-angle light scattering detector: optimization of crossflow rate, carrier characteristics and injected mass in alginate separation

Enrica Alasonati

The coupling of the flow field flow fractionation to differential refractive index (DRI) and multi-angle laser light scattering detectors is a powerful tool for characterizing charged polysaccharides such as alginate. However, the correct interpretation of ...
