Constant light element abundances suggest that the extended P1 in NGC 2808 is not a consequence of CNO-cycle nucleosynthesis

Recent photometric results have identified a new population among globular cluster stars. This population, referred to as the 'extended P1', has been suggested to be the manifestation of a new abundance pattern where the initial mass fraction of He changes ...

Three-dimensionalmodeling of the mixing state of particles over Greater Paris

Yi Zhang, Athanasios Nenes

A size-composition resolved aerosol model (SCRAM) is coupled to the Polyphemus air quality platform and evaluated over Greater Paris. SCRAM simulates the particle mixing state and solves the aerosol dynamic evolution taking into account the processes of co ...

Primary marine aerosol-cloud interactions off the coast of California

Athanasios Nenes, Robin Lewis Modini, Zheng Wang

Primary marine aerosol (PMA)-cloud interactions off the coast of California were investigated using observations of marine aerosol, cloud condensation nuclei (CCN), and stratocumulus clouds during the Eastern Pacific Emitted Aerosol Cloud Experiment (E-PEA ...

Atmospheric amines and ammonia measured with a chemical ionization mass spectrometer (CIMS)

Athanasios Nenes, Satoshi Takahama, Giulia Ruggeri, Hairun Guo

We report measurements of ambient amines and ammonia with a fast response chemical ionization mass spectrometer (CIMS) in a southeastern US forest and a moderately polluted midwestern site during the summer. At the forest site, mostly C3-amines (from pptv ...

A structure-based model of arterial remodeling in response to sustained hypertension

Nikolaos Stergiopoulos, Alkiviadis Tsamis, Alexander Rachev

A novel structure-based mathematical model of arterial remodeling in response to a sustained increase in pressure is proposed. The model includes two major aspects of remodeling in a healthy matured vessel. First, the deviation of the wall stress and flow- ...

Modeling and control of thermoacoustic instabilities

This work deals with modeling and control of thermoacoustic combustion instabilities in lean premixed combustion systems. Because of the complex interactions present in thermoacoustic systems, a network modeling approach is used. The model of each network ...

Polymer networks with grafted cell adhesion peptides for highly biospecific cell adhesive substrates

Jeffrey Alan Hubbell

Polymer networks of poly(ethylene glycol) (PEG) in densely cross-linked matrices of acrylic acid (AA) and trimethylolpropane triacrylate were synthesized as biospecific cell adhesive substrates. Networks grafted with synthetic adhesion peptides produced su ...
