Conformal Mapping and Bound States in Bent Waveguides
Conformal Mapping Bent Waveguides Quantum Physics
font style='font-size:12px;'>
2010/11/8
Is it possible to trap a quantum particle in an open geometry? In this work we deal with the boundary value problem of the stationary Schroedinger (or Helmholtz) equation within a waveguide with strai...
Novel Term in Fermion-Boson Mapping for Nuclear Rotation
Novel Term Fermion-Boson Mapping Nuclear Rotation
font style='font-size:12px;'>
2011/1/6
We introduce a novel term in fermion-boson mapping method for the Interacting Boson Model
(IBM) for rotational nuclei. The rotation of a given deformed nucleon system is similar to the
corresponding...
Mapping the initiation of plastic deformation in nanoindentation

font style='font-size:12px;'>
2010/11/17
Under the inhomogenous stress field set up by nanoindentation, the smaller the extent of the stress field the greater the yield pressure. When the specimen contains a thin layer of softer material, th...
"Meaning" as a sociological concept: A review of the modeling, mapping, and simulation of the communication of knowledge and meaning
sociological concept the modeling mapping

It is shown how, starting froma mapping theoremrecently proved between massless quartic scalar
field theory and Yang-Mills theory, both two-point functions and spectrum of the Yang-Mills
theory can ...
Duality mapping and unbinding transitions of semiflexible and directed polymers
Duality mapping unbinding transitions of semiflexible directed polymers
font style='font-size:12px;'>
2010/11/19
Directed polymers (strings) and semiflexible polymers (filaments) are one-dimensional objects governed by tension and bending energy, respectively.They undergo unbinding transitions in the presence of...

Suppose that $X$ and $Y$ are surfaces of finite topological type, where $X$ has genus $g\geq 6$ and $Y$ has genus at most $2g-1$; in addition, suppose that $Y$ is not closed if it has genus $2g-1$. O...
Spectroscopic [CI] mapping of the infrared dark cloud G48.65-0.29
Galaxy Astrophysics (astro-ph.GA)

We report the first spectroscopic mapping of an atomic carbon line in an infrared dark cloud (IRDC).
Mapping Dynamic Histone Acetylation Patterns to Gene Expression in Nanog-depleted Murine Embryonic Stem Cells
Mapping Dynamic Histone Acetylation Patterns Gene Expression in Nanog-depleted Murine Embryonic Stem Cells
font style='font-size:12px;'>
2010/11/15
Embryonic stem cells (ESC) have the potential to self-renew indefinitely and to differentiate into any of the three germ layers. The molecular mechanisms for self-renewal, maintenance of pluripotency ...
High-resolution mapping of the physical conditions in two nearby active galaxies based on 12CO(1-0), (2-1) and (3-2) lines
Galaxy Astrophysics (astro-ph.GA)
font style='font-size:12px;'>
2010/12/29
We present a detailed analysis of high resolution observations of the three lowest CO transitions in two nearby active galaxies, NGC4569 and NGC4826. The CO(1-0) and (2-1) lines were observed with the...
Importance of far-infrared mapping in a spiral galaxy: AKARI observation of M81
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2010/12/27
The importance of the far-infrared (FIR) mapping is demonstrated for a face-on spiral galaxy, M81, by analyzing its imaging data at 65, 90, and 140 {\mu}m taken by AKARI. Basic products are the dust t...
Spitzer Mapping of PAHs and H2 in Photodissociation Regions
Galaxy Astrophysics (astro-ph.GA)
font style='font-size:12px;'>
2010/12/22
The mid-infrared (MIR) spectra of dense photodissociation regions (PDRs) are typically dominated by emission from polycyclic aromatic hydrocarbons (PAHs) and the lowest pure rotational states of molec...
