AGB populations as probes of galaxy formation and evolution


The evolution of galaxies is driven by the birth and death of stars. Asymptotic Giant Branch (AGB) stars are at the end points of their evolution and therefore their luminosities directly reflect their birth mass; this enables us to reconstruct the star formation history (SFH). These cool stars also produce dust grains that play an important role in the temperature regulation of the interstellar medium, chemistry, and the formation of planets. These stars can be resolved in all of the nearby galaxies. Therefore, the Local Group of galaxies offers us a superb near-field cosmology site. Here we can reconstruct the formation histories, and probe ...

Eigenvalues and Structures of Weighted Graphs


Let S(G) be the set of all real symmetric matrices such that their offdiagonal entries are nonzero if and only if the corresponding vertices in the graph G are connected by an edge. The diagonal entries can be both zero and nonzero. In this talk, we will focus on the eigenvalues of these matrices. In particular, we are interested in q(G), the minimum number of distinct eigenvalues of a matrix in S(G). We will survey some results about the parameter q(G). ...

Superhydrophobicity in copper based layers


Superhydrophobicity in copper based layers


One of the relevant approaches to keep surfaces clean without a secondary process is to use the easy-to-clean and superhydrophobic surfaces technology. These superhydrophobic surfaces have a wide potential applications in the environment and industries. When the hydrophobicity is mixed with catalytic properties of copper oxide, a more useful surface for electrical and environmental applications is obtained. According to the recent researches, the preparation of one-step durable superhydrophobic surface whiteout a secondary chemical or physical modificatio ...

Hamiltonian structure of Multi-Gravity models


Abstract: In this talk, I will shortly review the recent results in Hamiltonian structure of Massive Gravity and HR Bi-Gravity in nonlinear level. Then, I will specifically focus on the Hamiltonian structure of three and four gravity. Finally, I present a perfect Hamiltonian structure for a multi-gravity model in the full phase space.

Metastability and Condensation (canceled)


Dynamical systems that are perturbed by small random noises are
known to exhibit
metastable behavior. Analogously, random walks with tendency towards a
finite collection of sites may exhibit metastability.
Zero Range Process is a random walk on a simplex with metastable states
residing at the vertices. Interpreting this process as a particle system on
a one dimensional lattice, the metastable states correspond to the
condensates. In this talk I give an overview of some known results in both
the continuous and discrete settings, and discuss some open questions. ...
