Biblical Scholarship in Louvain in the 'Golden' Sixteenth Century
No full textAntonio Gerace dealt with the development of biblical scholarship in Louvain by analysing with seven authors who worked in the first part of the Sixteenth century and who are strictly linked to the Louvain milieu. In chronological order, they include Nicholas Tacitus Zegers (c.1495–1559), John Henten (1499–1566), Cornelius Jansenius ‘of Ghent’, Adam Sasbout, John Hessels (1522–1566), Thomas Stapleton, and Francis Lucas ‘of Bruges’. Each author offered key-contributions that can effectively show the development of Catholic biblical scholarship in that period. This can be divided into three main thematic areas: 1) Text-criticism of the Latin Vulgate; 2) Exegesis of the Scriptures; and 3) Preaching of the Bible. Somehow, these three areas represent the ‘study flow’ of the Scriptures: the emendation of the Vulgate, aimed at restoring the text to a hypothetical ‘original’, and the philological approach to the Greek and Hebrew sources allowing for a better comprehension of the Bible. Such comprehension becomes the basis of commentaries made with the intention of explaining the meaning of the Scriptures to the faithful in the light of the Tradition. Furthermore, the Church needed to preach the Scriptures and their contents to the Catholic flock in order to safeguard them from any ‘heretical’ influence. Therefore, several homiletic works appeared so that priests could prepare their sermons appropriately. Therefore, Gerace divided his work into three parts, each devoted to one of the three research areas, following the ‘study-flow’ of the Scripturesedition: 1status: Publishe
What is the Vulgate? Girolamo Seripando's notes on the Vulgate
No full textBefore the issue of the Insuper decree (1546), by means of which the Council Fathers
declared the Vulgate to be the ‘authentic’ Bible for Catholic Church, Girolamo Seripando
took few notes discussing the need of a threefold Bible, in Latin, Greek and Hebrew,
as he stressed in the General Congregation on 3 April 1546. Only Rongy (1927/28),
Jedin (1937) and François/Gerace (2018) paid attention to this document, preserved at
the National Library in Naples in a manuscript of the 17th century (Ms. Vind. Lat. 66,
123v–127v). In this article, the author offers the very first transcription of these notes
together with the analysis of Seripando’s sources, providing a new primary source to
early modern historians
Analog Hawking radiation from an acoustic black hole in a flowing polariton superfluid
No full textWe theoretically study the analog Hawking radiation processes from an analog acoustic black hole in a flowing superfluid of exciton-polaritons in a one-dimensional semiconductor microcavity. Polaritons are coherently injected into the microcavity by a laser pump with a suitably tailored spot profile. An event horizon with a large analog surface gravity is created by inserting a defect in the polariton flow along the cavity plane. Experimentally observable signatures of the analog Hawking radiation are identified in the scattering of phonon wave packets off the horizon, as well as in the spatial correlation pattern of quantum fluctuations of the polariton density. The potential of these tabletop optical systems as analog models of gravitational physics is quantitatively confirmed by numerical calculations using realistic parameters for state-of-the-art devices
Francis Lucas ‘of Bruges’ and Textual Criticism of the Vulgate Before and After the Sixto-Clementine (1592)
No full textThis article deals with to the little known but very influential Leuven biblical scholar Francis Lucas ‘of Bruges’ (1548/9–1619). In particular, it traces the change of methodology in Lucas’ textual critical activity, due to publishing of the Sixto-Clementine Vulgate (1592), intended by the Vatican as the definitive text of the Vulgate. The author shows how Lucas was a realist and adapted his scholarly activities in the field of textual criticism to the contemporary ecclesiastical policies and sensitivities through the analysis of Lucas’ works.sponsorship: KULeuven/Fscirestatus: Publishe
Enhanced nonlinear properties of photonic crystal nanocavities
No full textPhotonic crystal cavities in silicon-on-insulator platforms have been designed to achieve very high quality factors and/or far-field input/output coupling. In this paper I will review our works on the use of these cavities to realize: record-high-Q resonators by genetic optimization of the holes, and bright light emission in an electrically pumped light-emitting diode. Finally, I will discuss theoretical predictions for the realization of quantum photonic devices, such as single-photon sources and diodes, in all-silicon or hybrid photonic crystal platforms
La determinazione della legge di Dio. Il pensiero del nómos in Paolo di Tarso
No full textThe article deals with the concept of ‘predestination’
and its development in the Bible. The word
that carries on this notion is the Greek verb προ-
ορίζω (proorízō), which occurs only in the New
Testament: once in the Acts of the Apostles and
five times in Paul’s Epistles. With a view to giving
a Christological interpretation of Paul’s words,
Allen in 1970 linked this verb to the word πρόσταγ-
μα (próstagma) that occurs in Psalm 2:7. However,
through a careful analysis of several passages
taken from both Greek and Jewish authors, such
as Demosthenes, Sophocles, Plato, Epictetus,
Heliodorus of Emesa, Philo of Alexandria and
Flavius Josephus, it might be possible to give a different
reading of Paul’s use of προορίζω. Indeed, it
seems that the Apostle of the Gentiles referred to
the technical legislative meaning of ὁρίζω (horízō),
viz. ‘I determine’ the law.status: Publishe
Interference Level Estimation for a Blind Source Separation in Document Restoration
No full textWe deal with the problem of blind separation of the components, in particular for documents corrupted by bleed-through and show-through. So, we analyze a regularization technique, which estimates the original sources, the interference levels and the blur operators. We treat the estimate of the interference levels, given the original sources and the blur operators. In particular, we investigate several GNC-type algorithms for minimizing the energy function. In the experimental results, we find which algorithm gives more precise estimates of the interference levels
Il Manipulus curatorum di Guy de Montrochen: 250 anni di formazione sacerdotale in Europa. Parte I
No full textbook for the education of the clergy in early modern Europe, Guy de Montrochen’s Manipulus curatorum (1330), printed from 1473 until 1581, when it saw the last of about 200 editions. This text was disseminated throughout Europe, revealing the need for such a handbook before the institution of seminaries (1563). In the first part of the essay, after the introduction to both Guy de Montrochen’s life and the historical context, attention was then paid to the editorial history of his handbook, after which the structure and the text of the Manipulus are examined. This second part indeed focuses on the analysis of the first section of the Manipulus, in which Guy deals with six of the sacraments, leaving aside penance, which is analysed in the second section of the Manipulus and will be the subject of a forthcoming contribution
Hybrid photonic technologies for quantum information tasks
No full textIn the last thirty years, Quantum Information has become an established research field, providing a unique framework to harness the properties of inherently quantum systems to process and transmit information in ways that surpass the capabilities of classical information processing. It has been shown how quantum-based approaches find several practical applications, such as quantum computing, simulation, metrology, and communication. In this context, thanks to continuous developments of photonic technologies, photon-based platforms have established themselves as an excellent experimental testbed for the demonstration and implementation of a wide range of Quantum Information Processing tasks. Within this framework, the main goal of the present Ph.D. thesis is to employ the toolbox of photon-based Quantum Information processing - together with the capabilities offered by a set of state-of-the-art photonic technologies related to photon generation, manipulation, and detection - to devise experimental platforms suitable for the demonstration of photon-based Quantum Information protocols. In this perspective, this work focused on developing a hybrid photonic architecture tailored for multiphoton Quantum Information experiments. I designed and assembled such a platform and characterized its underlying elements: Quantum Dot sources, time-to-spatial demultiplexing setups, and universal reconfigurable integrated photonic interferometers. This thesis's experimental results have been focused on the context of the characterization of multiphoton interference effects and the implementation of photon-based computational protocols. First, I experimentally investigated fully optical schemes suitable for the generation of polarization-based and orbital angular momentum-based entangled photon pairs via single photons emitted consecutively by a QD source. Then, given that the emergence of quantum interference effects in multiphoton scenarios is at the core of the concept of linear optical computing, I developed and validated, on one side, semi-device-independent techniques for characterizing multiphoton indistinguishability. On the other, I investigated the behavior of multiphoton interference effects in scenarios featuring partial distinguishability, where seemingly counterintuitive phenomena can arise. The last part of this Ph.D. thesis will be focused on the experimental realization of photon-based protocols related to quantum computing applications. I provided an experimental implementation of a hybrid quantum-classical technique that finds, via variational techniques, optimal linear optical circuits implementing a quantum cloning machine of dual-rail encoded qubits. Then, I considered a recently proposed routine for the manipulation of quantum randomness - the quantum-to-quantum Bernoulli Factory. I experimentally validated an architecture based on polarization-based encoding implementing such a protocol, exploiting the demultiplexed QD source interfaced with a fully in-bulk and modular interferometric setup. Finally, I employed the hybrid photonic architecture at its full capability to investigate a proof-of-principle photonic implementation of a so-called Adaptive Boson Sampling scheme, an approach that goes beyond the standard Boson Sampling paradigm via the addition of measurement-based adaptivity. Overall, the results reported here highlight the versatility of a hybrid photonic approach and may open the path toward increasingly complex demonstrations of photon-based platforms for Quantum Information tasks
