A Bayesian approach to dynamic efficiency and productivity measurement
(2017-02-17)The vast majority of the efficiency and productivity measurement literature has been based on the static viewpoint of the firm. Few studies have developed the dynamic analog of static efficiency measurement, introducing ... -
A Bayesian approach to initial model inference in cryo-electron microscopy
(2016-03-18)Single-particle cryo-electron microscopy (cryo-EM) is widely used to study the structure of macromolecular assemblies. Tens of thousands of noisy two-dimensional images of the macromolecular assembly viewed from different ... -
A Biased Urn Model for Taxonomic Identification
(2009-03-24)We consider a stochastic model for the problem of taxonomic identification in bacterial genomes, motivated by the detection of horizontal gene transfer between non-closely related species. ... -
A Bio-Inspired Autonomous Authentication Mechanism in Mobile Ad Hoc Networks
(2012-12-21)A Mobile Ad hoc NETwork (MANET) is an infrastructureless self-configuring network in that nodes themselves create and manage the network in a self-organized manner. Nodes can communicate only with their neighbors that ... -
A Bioinformatics Pipeline for Identifying Dysregulated Pathways in Cancer from Comparative RNA-Seq Transcriptome Analysis
(2022-04-07)Cancer is characterized as a multifactorial disease which undergoes genetic and epige- netic changes during invasive tumor growth. Thus, numerous tumor samples have been profiled using high-throughput sequencing technologies ... -
A Blessing in Disguise? Effects of Oil Palm Adoption on Smallholder Farmers’ Wellbeing and Agricultural Transformation in Indonesia
(2021-06-18)Dramatic land-use change in tropical regions due to oil palm expansion has recently raised controversies in the broader public. Indonesia is one of the countries where such rapid land-use change is happening. In many ... -
A candidate gene-based association study to investigate potentially adaptive genetic variation in European beech (Fagus sylvatica L.)
(2014-01-24)Climate change models predict higher annual mean temperatures as well as a decrease of precipitation during summer months for Germany. Possible consequences for trees are a prolonged growing season, a higher risk of late ... -
A case study for Skukuza: Estimating biophysical properties of fires using EOS-MODIS satellite data
(2003-12-15)Biomass burning in Africa, explicitly in Southern Africa, contributes excessively to the annual aerosol loading and pyrogenic gas emissions within the African atmospheric system. The frequency ... -
A cell-based NRG1-ERBB4 assay designed for high-throughput compound screening to identify small molecule modulators with relevance for schizophrenia
(2012-12-07)Summary A cell-based NRG1-ERBB4 assay designed for high-throughput compound screening to identify small molecule modulators with relevance for schizophrenia Schizophrenia (SZ) is as severe and phenotypically as well ... -
A Central Limit Theorem for Functions on Weighted Sparse Inhomogeneous Random Graphs
(2023-07-13)We prove a central limit theorem for a certain class of functions on weighted sparse inhomogeneous random graphs. The proof uses a perturbative form of Stein's method and relies on a careful analysis of the local structure ... -
A Characterization Theorem for Local Operators in Factorizing Scattering Models
(2013-01-10)In quantum field theory, the rigorous construction of local observables in the presence of nontrivial interaction is a crucial problem. In a class of integrable quantum field theories, a very abstract existence proof ... -
A Chimera simulation method and Detached Eddy Simulation for vortex-airfoil interactions
(2011-01-25)The present thesis introduces, verifies and validates a numerical simulation method based on an overset grid (or Chimera) technique that allows to simulate the generation and transport ... -
A classification of localizing subcategories by relative homological algebra
(2015-12-17)In this thesis, we use the tools of relative homological algebra in triangulated categories to define a sensible notion of support for objects in the bootstrap class of a Kasparov category of C*-algebras over a finite ... -
A colimit construction for groupoids
(2016-08-03)We consider Ore monoid actions in a certain bicategory of étale groupoids Gr_prop. Examples of such actions include self-similar groups, higher rank graphs and actions of Ore monoids on spaces by topological correspondences. ... -
A Comparison of Models and Methods for Spatial Interpolation in Statistics and Numerical Analysis
(2010-06-18)Interpolation of spatial data is a very general mathematical problem with many applications, such as surface reconstruction, the numerical solution of partial differential equations, learning ... -
A Content-Oriented Architecture for Publish/Subscribe Systems
(2015-04-01)With the user behavior of Internet shifting towards data dissemination and retrieval, Information Centric Networking (ICN) is proposed to suit these demands. ICN treats content as the first-class entity, with nodes exchanging ... -
A coronal loop in a box: From energy generation to coronal emission
(2023-03-17)The corona is the outer atmosphere of the Sun. It contains an abundance of bright arcs that consist of hot plasma trapped by the magnetic field. These coronal loops are heated to temperatures far surpassing the solar surface ... -
A cross-cultural study of motivational factors and values influencing purchase of organic food in Germany and Mexico.
(2010-09-15)The present dissertation compares the motives and values associated with the purchase of organic food in Germany and in Mexico. After an international literature review enough evidence ... -
