A quantitative analysis of the excitonic intensity borrowing for the J-/H-aggregates of the bacteriochlorophylls/chlorophylls (BChls/Chls) in specific, and of porphyrins in general, is presented. The analysis is based on the argument that the mixing between the two energetically well-separated bands, such as the Q and B bands of BChls/Chls, should be considered important if the aggregated system possesses an excitonic superstate. A remarkably simple explanation of the significance of the excitonic intensity borrowing is given: superhyperchromism is manifested by the mediation of interband coupling between the superstates in the two well- separated bands of such aggregates. A comprehensive discussion on the significance of superhyperchromism and on its size-dependence is provided in connection with its effects on the absorption spectra of the BChl/Chl J- and H-aggregates.

Expected Value of Partial Perfect Information in Hybrid Models Using Dynamic Discretization
Yet, Barbaros; Fenton, Norman; Neil, Martin (2018-01-01)
In decision theory models, expected value of partial perfect information (EVPPI) is an important analysis technique that is used to identify the value of acquiring further information on individual variables. EVPPI can be used to prioritize the parts of a model that should be improved or identify the parts where acquiring additional data or expert knowledge is most beneficial. Calculating EVPPI of continuous variables is challenging, and several sampling and approximation techniques have been proposed. This...
Analysis Of Interprovincial Service Flows For The Determination Of Provincial Hierarchy In Turkey
Berkman, Gülden (Middle East Technical University, Faculty of Architecture, 1976)
In this study, the analysis of interprovincial service flows -which is treated as complementary to the analysis of interprovincial commodity flows- will be presented. Thus, the resulting optimum distribution system can formulate the interprovincial, spatial hierarchical pattern. To give the interrelationships as a whole, the analysis will be carried out at the province scale, each province being considered a region. The method of Boudeville is resorted to for the computation of service flows. However, a dis...
Predicting financial distress of Turkish non-financial firms: evidence from micro data
Yılmaz, Muhammed Hasan; Ercan, Hakan; Department of Economics (2019)
In this thesis, determinants of financial distress probabilities are analyzed for the period over 2006-2016 by utilizing firm-level and loan-level data sets. Based on the financial distress definition constructed from the existence of non-performing loans, univariate tests indicate that financially problematic Turkish corporates have lower liquidity, profitability and asset turnover, while they are also the ones with inferior short and long-term debt paying ability. To form multivariate specifications, vari...
Effects of Non-Abelian Magnetic Fields on Pair Production in Flat and Curved Spaces
Özcan, Berk; Kürkçüoğlu, Seçkin; Department of Physics (2021-9)
Our objective in this thesis is to compute the pair production rates for both bosons and fermions under the influence of non-abelian gauge fields on the manifolds $\mathbb{R}^{3,1} \equiv \mathbb{R}^2 \times \mathbb{R}^{1,1}$ and $S^2 \times \mathbb{R}^{1,1}$. We will compare the pair production rates of the spherical cases with the flat ones, and also compare the non-abelian cases with the abelian ones to see effects of both curvature and non-abelian field strength on the pair production. We first review t...
Analysis of volatility feedback and leverage effects on the ISE30 index using high frequency data
Inkaya, A.; Okur, Y. Yolcu (Elsevier BV, 2014-03-15)
In this study, we employ the techniques of Malliavin calculus to analyze the volatility feedback and leverage effects for a better understanding of financial market dynamics. We estimate both effects for a general semimartingale model applying Fourier analysis developed in Malliavin and Mancino (2002) [10]. We further investigate their joint behaviour using 5 min data of the ISE30 index. On the basis of these estimations, we look for the evidence that volatility feedback effect rate can be employed in the s...
