Closed Form Absorption Time Bounds [chapter]

Ana Bušić, Nihal Pekergin
Lecture Notes in Computer Science  
We show that some absorbing chains can be also seen as members of this class and we provide the closed form solution for their absorption time distributions.  ...  By constructing upper and lower bounding chains that belong to this particular class one can easily compute both lower and upper bounds for absorption time distribution of an arbitrary absorbing Markov  ...  We show now that class C G matrices have also the closed form solution for the absorption time. Proposition 1.  ...

Chiral optical absorption by a single vortex in px±ipy-wave superconductor

Masashige Matsumoto, Manfred Sigrist
2000 Physica. B, Condensed matter  
Due to the violation of time reversal symmetry, there are two types of vortices whose winding orientation is the same or opposite to the angular momentum of the Cooper pair.  ...  However, optical absorption of circular polarized light depends only on the winding of the vortex and has a low energy absorption peak which results in dichroism.  ...  There are two kinds of bound states, one localized around the vortex (vortex bound state) and the other formed near the surface at r=R (surface bound state).  ...

Enantioselective Cyclization of Photochromic Dithienylethenes Bound to DNA

Tamara C. S. Pace, Vilhelm Müller, Shiming Li, Per Lincoln, Joakim Andréasson
2013 Angewandte Chemie International Edition  
In solution the achiral open form of symmetric DTEs or the racemic mixture (S,S + R,R) of the chiral closed form show no CD signal, however when bound to DNA induced CD signals are observed.  ...  The closed forms 1c and 2c have significant absorption in the visible region (Figure 1 ), and reverse isomerization using broadband visible light ( > 530 nm) converts both 1 and 2 to 100% open form.  ...

Absorption Spectral Analysis of Zn2+ or Cu2+ Coordination with Human Serum Albumin using Zincon

Koji Matsuura
2014 Journal of Analytical & Bioanalytical Techniques  
In this study, we found that metal ions and zincon bound to HSA, and that a complex was formed with the HSA molecule.  ...  The metal-coordinating zincon can bind to HSA and the unbound forms can be recognized by absorption spectroscopy.  ...  Next, we consider the possible reason for the peak red-shifts in HSA and the metal-bound zincon form based on the molecular structure of HSA.  ...
