The politics of the crucified: a study of the political theology of John Howard Yoder, Leonardo Boff and Jon Sobrino with special reference to the crucifixion
No full textJesus died violently on the cross, the form of execution imposed on those who threatened the Roman imperial order. What difference does this make to Christian political theology? What is the revelatory value of Jesus’ death with regard to political theology? This thesis explores these questions, using a Christocentric methodology and taking three theologians in particular as interlocutors -– the
Mennonite theologian John Yoder and the Latin American liberation theologians Leonardo Boff and Jon Sobrino – with special reference to an examination of the ways in which their political theologies are shaped by the cross. The first part of the thesis consists of a close analysis and comparison of the writings of the above theologians concerning the cross. In Yoder, the theme of a cruciform, non-violent and non-resistant church is emphasised. In Boff and Sobrino the cross is seen to represent a protest against suffering in the name of a crucified God in solidarity with a crucified people. In the second part of the thesis the perspective widens to examine two issues which particularly arise from this analysis – how a Christian doctrine of political power is affected by the crucifixion, and how the contemporary church, particularly in Britain, might adopt a ‘cruciform’ political praxis. The
conclusion is drawn that the chief Christian criterion for analysing political power is victimological – i.e. from the perspective of the victims of power, rather than those
who exercise it. In the light of this, and given its increasingly marginalised status, the church in Britain should abandon any pretensions to ‘Christendom’, formulate a
cruciform political theology and willingly live out a cruciform status
Christian nonconformity by J. H. Yoder and M. L. King
No full textThis Bachelor thesis with the title Christian nonconformity by J. H. Yoder and M. L. King, deals with the specific status of Christian in society. The first part of the thesis is dedicated to the ethical concept of J. H. Yoder and the second part is dedicated to the ethical concept of M. L. King. The final part is attempting to compare both approaches with a focus on nonconformity. In the comparison is persuaded the social aspect in particular and shows the relationship between the society and the Christians according both concepts. The author of the work uses as literal sources particularly the essays and speeches from M. L. King and from the book of J. H. Yodera: The politics of Jesus. Powered by TCPDF (www.tcpdf.org
Fixed-point adiabatic quantum search
No full textFixed-point quantum search algorithms succeed at finding one of M target items among N total items even when the run time of the algorithm is longer than necessary. While the famous Grover's algorithm can search quadratically faster than a classical computer, it lacks the fixed-point property—the fraction of target items must be known precisely to know when to terminate the algorithm. Recently, Yoder, Low, and Chuang [Phys. Rev. Lett. 113, 210501 (2014)] gave an optimal gate-model search algorithm with the fixed-point property. Previously, it had been discovered by Roland and Cerf [Phys. Rev. A 65, 042308 (2002)] that an adiabatic quantum algorithm, operating by continuously varying a Hamiltonian, can reproduce the quadratic speedup of gate-model Grover search. We ask, can an adiabatic algorithm also reproduce the fixed-point property? We show that the answer depends on what interpolation schedule is used, so as in the gate model, there are both fixed-point and non-fixed-point versions of adiabatic search, only some of which attain the quadratic quantum speedup. Guided by geometric intuition on the Bloch sphere, we rigorously justify our claims with an explicit upper bound on the error in the adiabatic approximation. We also show that the fixed-point adiabatic search algorithm can be simulated in the gate model with neither loss of the quadratic Grover speedup nor of the fixed-point property. Finally, we discuss natural uses of fixed-point algorithms such as preparation of a relatively prime state and oblivious amplitude amplification.American Society for Engineering Education.

Bio-Optical Measurements in Narragansett Bay, Rhode Island, 1999-2000
No full textThis document is based on 2 M.S. theses of former graduate students of Professor Emeritus James Yoder: S. A. Freeman (2001) and M. N. McFarland (2001), Section 1 and Section 2, respectively. Dr. Yoder made some edits and some deletions to both theses and also moved some of their material into Section 3, which also includes some of his own analyses and modeling. The purpose of this document is to merge closely related data and analyses into a single document and then to expand on the original conclusions with some additional calculations. The merged document thus tells a more complete story about the bio-optical measurements in Narragansett Bay that were made by Freeman and McFarland in 1999 and 2000. These were the first bio-optical measurements made in the Bay with modern equipment and may prove in the future be an important data set to help determine changes that may have occurred (be occurring). References cited were not updated from the original theses, which means that the Discussion does not compare the results with more recent studies
Quantum inference on Bayesian networks
No full textPerforming exact inference on Bayesian networks is known to be #P-hard. Typically approximate inference techniques are used instead to sample from the distribution on query variables given the values e of evidence variables. Classically, a single unbiased sample is obtained from a Bayesian network on n variables with at most m parents per node in time O(nmP(e)[superscript −1]), depending critically on P(e), the probability that the evidence might occur in the first place. By implementing a quantum version of rejection sampling, we obtain a square-root speedup, taking O(n2[superscript m]P(e)[superscript −1/2]) time per sample. We exploit the Bayesian network's graph structure to efficiently construct a quantum state, a q-sample, representing the intended classical distribution, and also to efficiently apply amplitude amplification, the source of our speedup. Thus, our speedup is notable as it is unrelativized—we count primitive operations and require no blackbox oracle queries.United States.

Hyperfine splitting of [Al VI] 3.66 mu m and the Al isotopic ratio in NGC 6302
No full textThe core of planetary nebula NGC 6302 is filled with high-excitation photoionized gas at low expansion velocities. It represents a unique astrophysical situation in which to search for hyperfine structure (HFS) in coronal emission lines from highly ionized species. HFS is otherwise blended by thermal or velocity broadening. Spectra containing [Al vr] 3.66 mu m P-3(2) <- P-3(1), obtained with Phoenix on Gemini South at resolving powers of up to 75000, resolve the line into five hyperfine components separated by 20-60 km s(-1) as a result of the coupling of the I = 5/2 nuclear spin of Al-27 with the total electronic angular momentum J. The isotope Al-26 has a different nuclear spin of I = 5, and a different HFS, which allows us to place a 3 sigma upper limit on the Al-26/Al-27 abundance ratio of 1/33. We measure the HFS magnetic dipole coupling constants for [Al vr], and provide the first estimates of the electric quadrupole HFS coupling constants obtained through astronomical observations of an atomic transition
Heisenberg scaling of imaging resolution by coherent enhancement
No full textClassical imaging works by scattering photons from an object to be imaged, and achieves resolution scaling as 1/√t, with t the imaging time. By contrast, the laws of quantum mechanics allow one to utilize quantum coherence to obtain imaging resolution that can scale as quickly as 1/t – the so-called “Heisenberg limit.” However, ambiguities in the obtained signal often preclude taking full advantage of this quantum enhancement, while imaging techniques designed to be unambiguous often lose this optimal Heisenberg scaling. Here we demonstrate an imaging technique which combines unambiguous detection of the target with Heisenberg scaling of the resolution. We also demonstrate a binary search algorithm which can efficiently locate a coherent target using the technique, resolving a target trapped ion to within 0.3% of the 1/e² diameter of the excitation beam.United States.
