Epistola Lutheriana ad Leonem decimum summum pontificem Tractatus de libertate Christiana
Creators: name: Luther, Martin, 1483-1546
Publisher: name: Columbia University
Year: 2019

description: In this preface to his key work On the Freedom of the Christian, Luther appeals directly to the Pope in his own defense and to address the failures of the Church. Luther is variously obsequious and brash in making his case:"Among those monstrous evils of this age with which I have now for three years been waging war, I am sometimes compelled to look to you and to call you to mind, most blessed father Leo. In truth, since you alone are everywhere considered as being the cause of my engaging in war, I cannot at any time fail to remember you; and although I have been compelled by the causeless raging of your impious flatterers against me to appeal from your seat to a future council...yet I have never been so alienated in feeling from your Blessedness as not to have sought with all my might, in diligent prayer and crying to God, all the best gifts for you and for your see. But those who have hitherto endeavored to terrify me with the majesty of your name and authority, I have begun quite to despise and triumph over."

description: In this thesis, we devise a new finite branch-and-bound algorithm for disjoint bilinear programs. In these problems, there are two vectors of variables, $\b{x}$ and $\b{y}$, and two polytopes $P_{\b{x}}$ and $P_{\b{y}}$ such that $\b{x}$ (resp. $\b{y}$) is chosen from $P_{\b{x}}$ (resp. $P_{\b{y}}$) so that a bilinear objective function is minimized. By a bilinear objective, we mean that the objective becomes linear when either one of $\b{x}$ or $\b{y}$ is fixed. This branch-and-bound scheme uses a relaxation that is derived using the reformulation-linearization technique (RLT). The RLT relaxation is constructed by taking products of constraints and linearizing the bilinear terms using introduced variables. The quality of this relaxation improves as higher order products and the corresponding monomial terms are linearized. Although it is known that, as RLT relaxations are constructed with increasingly higher order linearizations, the relaxation eventually converges to the true optimal value. However, no finite convergence properties are known. In contrast, we show that the first level of the RLT hierarchy suffices to convexify the problem when one of the polytopes is a simplex. Then, using this insight we devise a new class of relaxations by combining RLT with a variant of the double description procedure, where the latter lifts a polytope into a simplex in a finite number of steps. This leads us to a finite hierarchy of relaxations that converges to the optimal value. Although this hierarchy is finite, from a computational perspective, we find that the relaxations grow rapidly in size. However, we utilize the insight to derive a simplicial branch-and-bound scheme, that expresses each polytope as a union of simplices allowing us to converge finitely to the optimal solution for the problem. We perform preliminary numerical experiments to show that this approach holds promise and competes favorably with state-of-the-art methods on larger instances.

description: Simulations of many rigid bodies colliding with each other sometimes yield particularly interesting results if the colliding objects differ significantly in size and are non-spherical. The most expensive part within such a simulation code is the collision detection. We propose a family of novel multiscale collision detection algorithms that can be applied to triangulated objects within explicit and implicit time stepping methods. They are well-suited to handle objects that cannot be represented by analytical shapes or assemblies of analytical objects. Inspired by multigrid methods and adaptive mesh refinement, we determine collision points iteratively over a resolution hierarchy, and combine a functional minimisation plus penalty parameters with the actual comparision-based geometric distance calculation. Coarse surrogate geometry representations identify "no collision" scenarios early on and otherwise yield an educated guess which triangle subsets of the next finer level potentially yield collisions. They prune the search tree, and furthermore feed conservative contact force estimates into the iterative solve behind an implicit time stepping. Implicit time stepping and non-analytical shapes often yield prohibitive high compute cost for rigid body simulations. Our approach reduces these cost algorithmically by one to two orders of magnitude. It also exhibits high vectorisation efficiency due to its iterative nature.

description: This work addresses model order reduction for complex moving fronts, which are transported by advection or through a reaction–diffusion process. Such systems are especially challenging for model order reduction since the transport cannot be captured by linear reduction methods. Moreover, topological changes, such as splitting or merging of fronts pose difficulties for many nonlinear reduction methods and the small non-vanishing support of the underlying partial differential equations dynamics makes most nonlinear hyper-reduction methods infeasible. We propose a new decomposition method together with a hyper-reduction scheme that addresses these shortcomings. The decomposition uses a level-set function to parameterize the transport and a nonlinear activation function that captures the structure of the front. This approach is similar to autoencoder artificial neural networks, but additionally provides insights into the system, which can be used for efficient reduced order models. In addition to the presented decomposition method, we outline a tailored hyper-reduction method that is based on the reduced integration domain method. The capability of the approach is illustrated by various numerical examples in one and two spatial dimensions, including an advection–reaction–diffusion system with a Kolmogorov–Petrovsky–Piskunov reaction term and real life application to a two-dimensional Bunsen flame.

description: Internal waves are believed to be of primary importance as they affect ocean mixing and energy transport. Several processes can lead to the breaking of internal waves and they usually involve non linear interactions between waves. In this work, we study experimentally the parametric subharmonic instability (PSI), which provides an efficient mechanism to transfer energy from large to smaller scales. It corresponds to the destabilization of a primary plane wave and the spontaneous emission of two secondary waves, of lower frequencies and different wave vectors. Using a time-frequency analysis, we observe the time evolution of the secondary waves, thus measuring the growth rate of the instability. In addition, a Hilbert transform method allows the measurement of the different wave vectors. We compare these measurements with theoretical predictions, and study the dependence of the instability with primary wave frequency and amplitude, revealing a possible effect of the confinement due to the finite size of the beam, on the selection of the unstable mode.

description: We present a lattice QCD calculation of the parameters of the $ρ$ meson decay. The study is carried out on spatially asymmetric boxes using nHYP-smeared clover fermions with two mass-degenerate quark flavors. Our calculations are carried out at a pion mass $m_π=304(2)$ MeV on the set of lattices $V=24^2\times η24\times48$ with $η=1.0,1.25$, and 2.0 with lattice spacing $a=0.1255(7)$ fm. The resonance mass $m_ρ=827(3)(5)$ MeV and coupling constant $g_{ρππ}=6.67(42)$ are calculate using the P-wave scattering phase shifts. We construct a 2$\times$2 correlation matrix to extract the energy of the scattering states and compute the phase shifts using the finite volume formula. By varying the degree of asymmetry, we are able to compute a set of phase shifts that are evenly distributed throughout the spectral region where the $ρ$ decays.

description: We consider a fermion chirally coupled to a prescribed pseudoscalar field in the form of the soliton of the sine-Gordon model and calculate and investigate the Casimir energy and all of the relevant quantities for each parity channel, separately. We present and use a simple prescription to construct the simultaneous eigenstates of the Hamiltonian and parity in the continua from the scattering states. We also use a prescription we had introduced earlier to calculate unique expressions for the phase shifts and check their consistency with both the weak and strong forms of the Levinson theorem. In the graphs of the total and parity decomposed Casimir energies as a function of the parameters of the pseudoscalar field distinctive deformations appear whenever a fermionic bound state energy level with definite parity crosses the line of zero energy. However, the latter graphs reveal some properties of the system which cannot be seen from the graph of the total Casimir energy. Finally we consider a system consisting of a valence fermion in the ground state and find that the most energetically favorable configuration is the one with a soliton of winding number one, and this conclusion does not hold for each parity, separately.

description: Luther here argues in German for a full-scale overhaul of the Church, and that the secular powers of emperor and nobility had the authority and the responsibility to act in the face of a corrupted Church, whose members he dismissively referred to as "Romanists." He called for the end of major swathes of the medieval Church’s structure, including its elaborate calendar of feasts and saints days, and its vast industry of relics and pilgrimages. Among his demands was the abolition of clerical celibacy, arguing that to prohibit marriage was as futile as to "forbid eating, drinking, the natural movement of the bowels or growing fat." Though addressed primarily to non-ecclesiastical elites – whose support and protection were perhaps the main reason he survived through this period – the work uses populist rhetoric against the hierarchy of Church structures and teaching. It was reprinted at least fourteen times within just a few years. "Therefore…those who are now called ‘spiritual’ – priests, bishops, or popes – are neither different from other Christians, nor superior to them…." "...there is no true, basic difference between laymen and priests, princes and bishops, between religious and secular, except for the sake of office and work, but not for the sake of status….they all of the spiritual estate, all are truly priests, bishops, and popes." "...it may well happen that the pope and his followers are wicked men and not true Christians, not taught of God, not having true understanding. On the other hand, an ordinary man may have true understanding; why then should we not follow him?"

title: Ηλιακή φωτοκατάλυση ως μέθοδος απολύμανσης: παρασκευή καταλυτών και έλεγχος αδρανοποίησης παθογόνων βακτηρίων
Creators: name: Μακροπουλου Τατιανα
Publisher: name: Technical University of Crete
Year: 2018

description: Λόγω των σύγχρονων απαιτήσεων για παραγωγή νερού υψηλής ποιότητας απαλλαγμένου από παθογόνους μικροοργανισμούς, οι ερευνητές έχουν στρέψει την προσοχή τους στην ανάπτυξη βιώσιμων και αποδοτικών τεχνικών απολύμανσης. Σε αυτό το πλαίσιο, η παρούσα εργασία μελετά την ηλιακή φωτοκατάλυση ως μέθοδο απολύμανσης.

Σκοπός της εργασίας, είναι η σύνθεση και ο χαρακτηρισμός φωτοκαταλυτών ενισχυμένων με άζωτο και η αξιολόγηση τους ως προς την ικανότητα να αδρανοποιούν μικροβιακά στελέχη των Escherichia coli, Pseudomonas aeruginosa και Bacillus cereus σε υδατικά διαλύματα υπό προσομοιωμένη ηλιακή ακτινοβολία.

Οι Ν-TiO2 φωτοκαταλύτες παρασκευάστηκαν με μία μέθοδο που βασίζεται στην τεχνική λύματος- πηκτώματος (sol- gel) με διαφορετικές πρόδρομες ενώσεις (ουρία, τριαιθυλαμίνη-ΤΕΑ και αμμωνία-ΝΗ3). Η ενίσχυση με άζωτο προσδίδει στους καταλύτες μειωμένο ενεργειακό χάσμα και βελτιωμένη απόκριση στην ορατή ακτινοβολία. Η ενεργότητα των Ν-TiO2 φωτοκαταλυτών, επηρεάζεται από το είδος του υπό εξέταση μικροοργανισμού και υπερισχύει σε κάθε περίπτωση συγκριτικά με αυτήν των μη ενισχυμένων. Η απόδοση των φωτοκαταλυτών σύμφωνα με τη βακτηριοκτόνο δράση τους οδηγεί στην ακόλουθη ταξινόμησή τους: N-TiO2 (UREA)> N-TiO2 (NH3) ~N-TiO2 (TEA)> (συντεθειμένος)TiO2> TiO2-P25. Τα Gram-αρνητικά βακτήρια E. coli και P. aeruginosa αδρανοποιήθηκαν εύκολα καθώς παρατηρείται μείωση της τάξης 6 Log μέσα σε 60 min επεξεργασίας, με αρχική συγκέντρωση μικροβιακού πληθυσμού 106 CFU mL-1 και συγκέντρωση καταλύτη 50 mg L-1. Ωστόσο, οι φωτοκαταλύτες έδειξαν διαφορετική απολυμαντική ικανότητα όσον αφορά στον κατά Gram θετικό B. cereus, ο οποίος εμφανίζει μεγαλύτερη ανθεκτικότητα. Η μέγιστη απομάκρυνση, του εν λόγω βακτηρίου, είναι της τάξης 4 Log μετά από 60 min επεξεργασίας παρά τη μικρότερη αρχική συγκέντρωση του μικροβιακού πληθυσμού (105 CFU mL-1). Ολική αδρανοποίηση του B. cereus, στον ίδιο χρόνο επεξεργασίας, επιτυγχάνεται μόνο παρουσία του φωτοκαταλύτη N-TiO2 (TEA) μετά από αύξηση της συγκέντρωσής του στην τιμή 100 mg L-1. Σε κανέναν από τους τρεις επιλεγμένους βιοδείκτες δεν παρατηρείται σημαντική επανενεργοποίηση, μετά την απολύμανση.

Επιπρόσθετα, η αύξηση της συγκέντρωσης της τριαιθυλαμίνης (από 25 σε 50 και 89 v/v%) κατά τη σύνθεση, δεν βελτιώνει τις οπτικές ιδιότητες των N-TiO2 φωτοκαταλυτών και ως εκ τούτου δεν ενισχύει την απολυμαντική τους ικανότητα.

Οι λειτουργικές παράμετροι που εξετάστηκαν - όπως η συγκέντρωση καταλύτη, το είδος της πρόδρομης ουσίας, το είδος του μικροοργανισμού, η συγκέντρωση της πρόδρομης ουσίας και η πηγή ακτινοβολίας - μεταβάλλουν την απόδοση της διεργασίας σε διαφορετικό βαθμό, με το είδος του μικροοργανισμού να παίζει καθοριστικό ρόλο.

Το γενικό συμπέρασμα που προκύπτει είναι ότι η ηλιακή φωτοκατάλυση με χρήση N-TiO2 καταλυτών μπορεί να είναι μια αποτελεσματική μέθοδος απολύμανσης, αν ο σχεδιασμός και η ρύθμιση των λειτουργικών παραμέτρων γίνεται σύμφωνα με το κατά περίπτωση μικροβιακό φορτίο του νερού.

description: We study aperiodic balanced sequences over finite alphabets. A sequence vv of this type is fully characterised by a Sturmian sequence u and two constant gap sequences y and y'. We show that the language of v is eventually dendric and we focus on return words to its factors. We develop a method for computing the critical exponent and asymptotic critical exponent of balanced sequences, provided the associated Sturmian sequence u has a quadratic slope. The method is based on looking for the shortest return words to bispecial factors in v. We illustrate our method on several examples; in particular we confirm a conjecture of Rampersad, Shallit and Vandomme that two specific sequences have the least critical exponent among all balanced sequences over 9-letter (resp., $0-letter) alphabets.

description: The effect of external electric field on electron-hole correlation in GaAs quantum dots is investigated. The electron-hole Schrodinger equation in the presence of external electric field is solved using explicitly correlated full configuration interaction (XCFCI) method and accurate exciton binding energy and electron-hole recombination probability are obtained. The effect of the electric field was included in the 1-particle single component basis functions by performing variational polaron transformation. The quality of the wavefunction at small inter-particle distances was improved by using Gaussian-type geminal function that depended explicitly on the electron-hole separation distance. The parameters of the explicitly correlated function were determined variationally at each field strength. The scaling of total exciton energy, exciton binding energy, and electron-hole recombination probability with respect to the strength of the electric field was investigated. It was found that a 500 kV/cm change in electric field reduces the binding energy and recombination probability by a factor of 2.6 and 166, respectively. The results show that the eh-recombination probability is affected much more strongly by the electric field than the exciton binding energy. Analysis using the polaron-transformed basis indicates that the exciton binding should asymptotically vanish in the limit of large field strength.

description: Nonlinear devices, such as transistors, enable contemporary computing technologies. We theoretically investigate nonlinear effects, bearing a high fundamental scientific and technical relevance, in magnonics with emphasis on superconductor-ferromagnet hybrids. Accounting for finite magnon chemical potential, we theoretically demonstrate magnonic spin-Joule heating, the spin analogue of conventional electronic Joule heating. Besides suggesting a key contribution to magnonic heat transport in a broad range of devices, it provides insights into the thermal physics of non-conserved bosonic excitations. Considering a spin-split superconductor self-consistently, we demonstrate its interface with a ferromagnetic insulator to harbor large tunability of spin and thermal conductances. We further demonstrate hysteretic rectification I-V characteristics in this hybrid, where the hysteresis results from the superconducting state bistability.

description: This article establishes the performance of stochastic blockmodels in addressing the co-clustering problem of partitioning a binary array into subsets, assuming only that the data are generated by a nonparametric process satisfying the condition of separate exchangeability. We provide oracle inequalities with rate of convergence $\mathcal{O}_P(n^{-1/4})$ corresponding to profile likelihood maximization and mean-square error minimization, and show that the blockmodel can be interpreted in this setting as an optimal piecewise-constant approximation to the generative nonparametric model. We also show for large sample sizes that the detection of co-clusters in such data indicates with high probability the existence of co-clusters of equal size and asymptotically equivalent connectivity in the underlying generative process.

description: We consider nonlinear parabolic equations of the type $$ u_t - div a(x, t, Du)= f(x,t) on Ω_T = Ω\times (-T,0), $$ under standard growth conditions on $a$, with $f$ only assumed to be integrable. We prove general decay estimates up to the boundary for level sets of the solutions $u$ and the gradient $Du$ which imply very general estimates in Lebesgue and Lorentz spaces. Assuming only that the involved domains satisfy a mild exterior capacity density condition, we provide global regularity results.

description: We have developed the laser-diode-heated floating zone (LDFZ) method, in order to improve the broad and inhomogeneous light focusing in the conventional lamp-heated floating zone method, which often causes difficulties in the crystal growth especially for the incongruently melting materials. We have simulated the light focusing properties of the LDFZ method to make irradiated light homogeneous and restricted mostly to the molten zone. We have designed and assembled an LDFZ furnace, and have demonstrated how it works through actual crystal growth. The method is applicable to various kinds of materials, and enables stable and reproducible crystal growth even for the incongruently melting materials. We have succeeded in the crystal growth of representative incongruently melting materials such as BiFeO3 and (La,Ba)2CuO4, which are difficult to grow by the conventional method. Tolerance to the decentering of the sample and highly efficient heating are also established in the LDFZ method.

description: Reshef et al. recently proposed a new statistical measure, the "maximal information coefficient" (MIC), for quantifying arbitrary dependencies between pairs of stochastic quantities. MIC is based on mutual information, a fundamental quantity in information theory that is widely understood to serve this need. MIC, however, is not an estimate of mutual information. Indeed, it was claimed that MIC possesses a desirable mathematical property called "equitability" that mutual information lacks. This was not proven; instead it was argued solely through the analysis of simulated data. Here we show that this claim, in fact, is incorrect. First we offer mathematical proof that no (non-trivial) dependence measure satisfies the definition of equitability proposed by Reshef et al.. We then propose a self-consistent and more general definition of equitability that follows naturally from the Data Processing Inequality. Mutual information satisfies this new definition of equitability while MIC does not. Finally, we show that the simulation evidence offered by Reshef et al. was artifactual. We conclude that estimating mutual information is not only practical for many real-world applications, but also provides a natural solution to the problem of quantifying associations in large data sets.
Repulsive interaction helps superconductivity in fullerides

description: A repulsive interaction model of superconductivity (SC) is studied for tight-binding models with three-fold degenerate molecular orbitals. Taking a weak-coupling approach, we derive dimensionless coupling constants for various symmetries of SC pairs. In addition to anisotropic SC pairs, the s-wave pairing ($A_g$) can also be formed. With the purely repulsive interaction, however, the $A_g$ pair is not the most stable in both bcc and fcc lattices. The most stable SC pair for the bcc lattice has the $T_g$ symmetry, which is favored by a strongly nesting Fermi surface. In the fcc lattice, various SC symmetries have comparable coupling strengths. With the electron-phonon interaction combined, it is likely that the $A_g$ pair becomes the most stable.

description: These lecture notes give a pedagogical introduction to phase transitions in disordered quantum systems and to the exotic Griffiths phases induced in their vicinity. We first review some fundamental concepts in the physics of phase transitions. We then derive criteria governing under what conditions spatial disorder or randomness can change the properties of a phase transition. After introducing the strong-disorder renormalization group method, we discuss in detail some of the exotic phenomena arising at phase transitions in disordered quantum systems. These include infinite-randomness criticality, rare regions and quantum Griffiths singularities, as well as the smearing of phase transitions. We also present a number of experimental examples.

Von der freyheyt eynes Christen menschen / Martinus Luther. Czu Vuittenbergk Im XX iar

Publisher: name: Columbia University
Year: 2019

description: Arguably Luther’s best-known work, it was reprinted no less that eighteen times in its first few years. It is a searching treatment of key theological and ethical issues such as freedom and grace, and religious quandaries such as: if a person is "justified" or "saved" by grace apart from any works he or she might do, what is the point of living a moral life? Luther’s language is often paradoxical, as for example in its famous opening line: "A Christian is the most free lord of all, and subject to none; a Christian is the most dutiful servant of all, and subject to everyone." and: "Here is the truly Christian life, here is faith really working by love, when a man applies himself with joy and love to the works of that freest servitude in which he serves others voluntarily and for nothing, himself abundantly satisfied in the fullness and riches of his own faith." One historian has recently summarized a key message of this work in contemporary, colloquial terms: Luther "told a sound psychological truth: Relationships of love are not played by rules."

description: In this series of papers, the primary goal is to enumerate Hamiltonian cycles (HC's) on the grid cylinder graphs $P_{m+1}\times C_n$, where $n$ is allowed to grow whilst $m$ is fixed. In Part~I, we studied the so-called non-contractible HC's. Here, in Part~II, we proceed further on to the contractible case. We propose two different novel characterizations of contractible HC's, from which we construct digraphs for enumerating the contractible HC's. Given the impression which the computational data for $m \leq 9$ convey, we conjecture that the asymptotic domination of the contractible HC's versus the non-contractible HC's, among the total number of HC's, depends on the parity of $m$.}

Entrainment of the intrinsic dynamics of single isolated neurons by natural-like input

Subjects: subject: Neurons and Cognition (q-bio.NC)

description: Neuronal dynamics is intrinsically unstable, producing activity fluctuations that are essentially scale-free. Here we show that while these scale-free fluctuations are independent of temporal input statistics, they can be entrained by input variation. Joint input output statistics and spike train reproducibility in synaptically isolated cortical neurons were measured in response to various input regimes over extended time scales (many minutes). Response entrainment was found to be maximal when the input itself possesses natural-like, scale-free statistics. We conclude that preference for natural stimuli, often observed at the system level, exists already at the elementary, single neuron level.

A coordinated optical and X-ray spectroscopic campaign on HD179949: searching for planet-induced chromospheric and coronal activity

description: HD179949 is an F8V star, orbited by a close-in giant planet with a period of ~3 days. Previous studies suggested that the planet enhances the magnetic activity of the parent star, producing a chromospheric hot spot which rotates in phase with the planet orbit. However, this phenomenon is intermittent since it was observed in several but not all seasons. A long-term monitoring of the magnetic activity of HD179949 is required to study the amplitude and time scales of star-planet interactions. In 2009 we performed a simultaneous optical and X-ray spectroscopic campaign to monitor the magnetic activity of HD179949 during ~5 orbital periods and ~2 stellar rotations. We analyzed the CaII H&K lines as a proxy for chromospheric activity, and we studied the X-ray emission in search of flux modulations and to determine basic properties of the coronal plasma. A detailed analysis of the flux in the cores of the CaII H&K lines and a similar study of the X-ray photometry shows evidence of source variability, including one flare. The analysis of the the time series of chromospheric data indicates a modulation with a ~11 days period, compatible with the stellar rotation period at high latitudes. Instead, the X-ray light curve suggests a signal with a period of ~4 days, consistent with the presence of two active regions on opposite hemispheres. The observed variability can be explained, most likely, as due to rotational modulation and to intrinsic evolution of chromospheric and coronal activity. There is no clear signature related to the orbital motion of the planet, but the possibility that just a fraction of the chromospheric and coronal variability is modulated with the orbital period of the planet, or the stellar-planet beat period, cannot be excluded. We conclude that any effect due to the presence of the planet is difficult to disentangle.

Dynamics of Spin Helices in the One-Dimensional $XX$ Model

description: Motivated by cold-atom experiments and a desire to understand far-from-equilibrium quantum transport, we analytically study the dynamics of spin helices in the one-dimensional $XX$ model. We use a Jordan-Wigner transformation to map the spin chain onto a non-interacting Fermi gas with simple equations of motion. The resulting dynamics are nontrivial, however, as the spin-helix initial condition corresponds to a highly nonequilibrium distribution of the fermions. We find a separation of timescales between the in-plane and out-of-plane spin dynamics. We gain insights from analyzing the case of a uniform spin chain and from a semiclassical model. One of our key findings is that the spin correlation functions decay as $t^{-1/2}$ at long time, in contrast to the experimentally observed exponential decay.
