Judas Iscariot: a vehicle of medieval didacticism
Creators: name: Kahn, Jeffrey
Publisher: name: University of Utah
Year: 2019

description: The role of Judas Iscariot in the French Passion plays of the f1iddle Ages shows itself to be of particular interest, not only because of the possible interpretations offered by this figure of semi-darkness, but also because some authors of fifteenth-century Mystery plays inserted a very curious legend, similar to the story of Oedipus, which gives a heretofor unrevealed aspect to the character of the apostleo The role of Judas is studied in the seven French Passion plays ranging from the beginnin of the fourteenth to the end of the fifteenth century the Passion du Palatinu, the Passion d'Autun, the Passion Sainte-Genevieve, the Passion de Semur, the Passion d'Arras, the Mystere de 1a Pas.§ion of Ar-n ou L Greban, and the Myster'e de la Passioq of Jean f1ichelo I have divided my analysis of Judas into three main parts, each one emphasizing for a definite didactic purpose a different aspect of the apostle's charactero For each of the three parts there is an introduction showing the needs of the public and placing each play in its historical settingo The plays of the first part are a dramatized paraphrased version of the Bible, portraying Judas as a kind of anti-Christ, with his main characteristic being hatred. In the second part, devoted to the Passion d'Arras, we find a dramatized "morality" satirizing the merchant class. Here the apostle's main characteristics are deceit and avarice. He is the personification of greedo The third part, dealing with the fusion of Oedipodean traits in the legend of Judas, is a dramatized "exemplum condeming incest as the root of evilo As part of my conclusion, I have examined Judas in a contemporary play, Judas by Marcel Pagnol, in order to give some idea of the evolution of thought as it relates to the man anc. his crimeo In Pagnol's play Judas reaches the essence of his beingo His pride crushed, he finally gains insight into the nature of his own being and his place on earth. In studying the characterizations of Judas in the various plays I have tried to show that many of the similarities of phrase, arrangement, and general development arise from the fact that the same texts often served as the basis for the representations given in different communities. These texts were at various times subjected to revision, and it is the successive alterations made upon them which have in many cases concealed their original connectionso In considering each play, I have tried to envisage the dramatic execution, at least as much as can be derived from the specific part of Judas in the text. But it is above all the psychology of the traitor which has interested me, and I have tried to draw from it Judas' essential as well as secondary traits to show with what ingenuity the authors described the betrayal and the betrayer.

Signore Giovanni Francesco Padrone Riverendissimo

Ritrovomi debitore di aver tardato fino a quest’ora a rispondere alla compitissima sua delli 29 settembre. Spero però di ricevere da ella un benigno compatimento, perche speravo di giorno in giorno ricevere la scattola con entro il pezzo di legno inpietrito, che in detta sua avisavami di aver spedito in Venezia al Pre Maestro Coronelli. Passati che furono varj giorni, e vedendo che non ricevevo notizia di detta scattola, ne scrissi al detto Padre, ma ne meno ricevei risposta. Su tale motivo mi portai ai Francescani facendo ricerca di che era del Pre Coronelli, ed ebbi in risposta che stava male a morte, ma ora sento che si vada rimetendo. Da questo mio sincero raconto ella ben vede non essere stata mia intenzione di tardar tanto a renderne le dovute grazie, come ora fo al presente assicurandola, che bramerò sempre tutte le occasioni per poterle corrispondere.
Ho sentito il piacere, che ha provato per le mie picciole fatiche, che a terminarle ci vole ancora del tempo, e se vi fossi ancora vicino non mi azzarderei a porre fuori un Prospectus perche stimarei dificile che qui in Italia si trovasse un numero bastante di soscrittori, perche pochi si dilettano d’istoria naturale.
Ella poi mi promette un certo muschio assai particolare, e certe nerite ( ?) ; si dell’uno, che dell’altro ce ne sarò molto tennuto.
[fol. 251v] Nel mese di settembre Mons. de Reaumur mi favori il quinto volume delle memoire sopra gl’insetti. Tutti sono parti degni di un tanto uomo, ma quest’ultimo, al mio corto discernimento, e forsi il più bello. In esso tratta di varie mosche, delle cighale, e delle api domestiche, e sopra a queste ultime si dirende molto.
Qui poi ai quattro si fece vedere la neve, e quasi ogni giorno si fa vedere, ma non fermasi interra, e bensi vero, che è cosa assai rara farsi la vendemia con la neve, e giaccio. Ella intanto mi conservi il suo amore, mi comandi, che troverammi prontissimo in servirla.

Merger and reconnection of Weibel separated relativistic electron beam

description: The relativistic electron beam (REB) propagation in a plasma is fraught with beam plasma instabilities. The prominent amongst them being the collisionless Weibel destabilization which spatially separates the forward propagating REB and the return shielding currents. This results in the formation of REB current filaments which are typically of the size of electron skin depth during the linear stage of the instability. It has been observed that in the nonlinear stage the filaments size increases as they merge with each other. With the help of 2D PIC simulations in the plane perpendicular to the REB propagation, it is shown that these mergers occur in two distinct nonlinear phases. In the first phase, the total magnetic energy increases. Subsequently, however, during the second phase, one observes a reduction in magnetic energy. It is shown that the transition from one nonlinear regime to another occurs when the typical current associated with individual filaments hits the Alfven threshold. In the second nonlinear regime, therefore, the filaments can no longer permit any increase in current. Magnetic reconnection events then dissipate the excess current (and its associated magnetic energy) that would result from a merger process leading to the generation of energetic electrons jets in the perpendicular plane. At later times when there are only few filaments left the individual reconnection events can be clearly identified. It is observed that in between such events the magnetic energy remains constant and shows a sudden drop as and when two filaments merge. The electron jets released in these recon- nection events are thus responsible for the transverse heating which has been mentioned in some previous studies [Honda et al. Phys. Plasmas 7, 1302 (2000)].

description: Some connections between different definitions of Levy Laplacians in the stochastic analysis are considered. Two approaches are used to define these operators. The standard one is based on the application of the theory of Sobolev-Schwartz distributions over the Wiener measure (the Hida calculus). One can consider the chain of Levy Laplacians parametrized by a real parameter with the help of this approach. One of the elements of this chain is the classical Levy Laplacian. Another approach to define the Levy Laplacian is based on the application of the theory of Sobolev spaces over the Wiener measure (the Malliavin calculus). It is proved that the Levy Laplacian defined with the help of the second approach coincides with one of the elements of the chain of Levy Laplacians, which is not the classical Levy Laplacian, under the imbedding of the Sobolev space over the Wiener measure into the space of generalized functionals over this measure. It is shown which Levy Laplacian in the stochastic analysis is connected to the gauge fields.

description: Quantization of a damped harmonic oscillator leads to so called Bateman's dual system. The corresponding Bateman's Hamiltonian, being a self-adjoint operator, displays the discrete family of complex eigenvalues. We show that they correspond to the poles of energy eigenvectors and the corresponding resolvent operator when continued to the complex energy plane. Therefore, the corresponding generalized eigenvectors may be interpreted as resonant states which are responsible for the irreversible quantum dynamics of a damped harmonic oscillator.

description: Effective cavities can be optically-induced in atomic media and employed to strengthen optical nonlinearities. Here we study the integration of induced cavities with a photonic quantum gate based on Rydberg blockade. Accounting for loss in the atomic medium, we calculate the corresponding finesse and gate infidelity. Our analysis shows that the conventional limits imposed by the blockade optical depth are mitigated by the induced cavity in long media, thus establishing the total optical depth of the medium as a complementary resource.
Active nematic gels as active relaxing solids

description: I put forward a continuum theory for active nematic gels, defined as fluids or suspensions of orientable rodlike objects endowed with active dynamics, that is based on symmetry arguments and compatibility with thermodynamics. The starting point is our recent theory that models (passive) nematic liquid crystals as relaxing nematic elastomers. The interplay between viscoelastic response and active dynamics of the microscopic constituents is naturally taken into account. By contrast with standard theories, activity is not introduced as an additional term of the stress tensor, but it is added as an external remodeling force that competes with the passive relaxation dynamics and drags the system out of equilibrium. In a simple one-dimensional channel geometry, we show that the interaction between non-uniform nematic order and activity results in either a spontaneous flow of particles or a self-organization into sub-channels flowing in opposite directions.

The data was collected from the Slashdot Zoo feature where users of the website can tag other users as friends and foes, providing positive and negative endorsements. We adapt social network analysis techniques to the problem of negative edge weights. In particular, we consider signed variants of global network characteristics such as the clustering coefficient, node-level characteristics such as centrality and popularity measures, and link-level characteristics such as distances and similarity measures. We evaluate these measures on the task of identifying unpopular users, as well as on the task of predicting the sign of links and show that the network exhibits multiplicative transitivity which allows algebraic methods based on matrix multiplication to be used. We compare our methods to traditional methods which are only suitable for positively weighted edges.

description: Arkani-Hamed, Dimopoulous, and Dvali have proposed a model of low-scale quantum gravity featuring large extra dimensions. In this model, the exchange of Kaluza-Klein towers of gravitons can enhance the production rate of electron and photon pairs at high invariant mass in proton-antiproton collisions. The amount of enhancement is characterized by the parameter $M_S$, the fundamental Planck scale in the bulk extra dimensions. We have searched for this effect using 100 pb$^{-1}$ of diphoton data and 110 pb$^{-1}$ of dielectron data collected with the Collider Detector at Fermilab at $\sqrt{s}=1.8$ TeV during the 1992-1996 run. In the absence of a signal, we place 95% confidence-level limits on $M_S$ of 905 GeV/$c^2$ and 826 GeV/$c^2$, for the case of constructive and destructive graviton interference respectively.

Individual features exhibit apparent motions of 10 to 20 arcsec per year, independently confirmed by near-infrared observations. The observed tangential velocities are at roughly the speed of light. It is likely that the moving structures are infrared echoes, in which interstellar dust is heated by the explosion and by flares from the compact object near the center of the remnant.

title: Third-Eye

description: The Third-Eye Device is a peripheral device compatible with any firearm equipped with the Picatinny rail system. Its system of a camera attached to the weapon which connects to an eyepiece allows the user to aim the weapon without aiming down the sights. This device is potentially crucial to those who regularly engage in close-quarters combat such as police and military specialists, whose ability to quickly and accurately clear rooms during operations is critical to their safety and the safety of others. The student team was tasked with improving the device, primarily in its survivability in dusty and wet environments, its resistance to impact, and its accuracy at the expected ranges of operation. The impact resistance was to be tested against military standards for dropping. The waterproofing and dustproofing was to be tested against international Ingress Protection ratings. To that end, the student team redesigned the exoskeletons of both the transmitter and receiver to be watertight and impact-resistant. They were also designed to fit a new camera system, updated circuit boards, and an improved battery. Also included in the update were a variety of usability updates, including a side rail on the attachment for a flashlight or laser sight, simplified power, channel switching, and recording buttons, an unobstructive helmet mount, and power and channel indicators. The team created a prototype of the exoskeletons. Although only limited physical testing of the device was possible, the team concluded the device would be sufficient to meet the key requirements and exceeded expectations in the adding of new features.
Circumstellar Dust Disks in Taurus-Auriga: The Submillimeter Perspective

Year: 2005

description: We present a sensitive, multiwavelength submillimeter continuum survey of 153 young stellar objects in the Taurus-Auriga star formation region. The submillimeter detection rate is 61% to a completeness limit of ~10 mJy (3-sigma) at 850 microns. The inferred circumstellar disk masses are log-normally distributed with a mean mass of ~0.005 solar masses and a large dispersion (0.5 dex). Roughly one third of the submillimeter sources have disk masses larger than the minimal nebula from which the solar system formed. The median disk to star mass ratio is 0.5%. The empirical behavior of the submillimeter continuum is best described as F_nu ~ nu^(2.0 +/- 0.5) between 350 microns and 1.3 mm, which we argue is due to the combined effects of the fraction of optically thick emission and a flatter frequency behavior of the opacity compared to the ISM. This latter effect could be due to a substantial population of large dust grains, which presumably would have grown through collisional agglomeration. In this sample, the only stellar property that is correlated with the outer disk is the presence of a companion. We find evidence for significant decreases in submillimeter flux densities, disk masses, and submillimeter continuum slopes along the canonical infrared spectral energy distribution evolution sequence for young stellar objects. The fraction of objects detected in the submillimeter is essentially identical to the fraction with excess near-infrared emission, suggesting that dust in the inner and outer disk are removed nearly simultaneously.

description: Since its discovery in 1966, the photorefractive effect, i.e. the change of the refractive index upon illumination with light, has been studied extensively in various materials and has turned out to play a key role in modern optical technologies like photonics. This article focuses on substances that change their refractive index for neutrons when irradiated with light. In analogy to light optics, we call them photo-neutronrefractive. After a short introduction to the relevant concepts of neutron optics, two materials exhibiting that effect, a photopolymer and an electrooptic crystal, are presented. Further, we discuss the the progress made concerning the development of creating light-induced gratings for neutron diffraction, which culminated in the setup of an interferometer for cold neutrons. Experiments performed on photo-neutronrefractive materials are surveyed and the variety of corresponding results obtained is presented, including a discussion of their impact on material science, neutron optics, and the foundations of physics.

description: In this theoretical paper, we investigate coherence properties of the near-resonant light scattered by two atoms exposed to a strong monochromatic field. To properly incorporate saturation effects, we use a quantum Langevin approach. In contrast to the standard optical Bloch equations, this method naturally provides the inelastic spectrum of the radiated light induced by the quantum electromagnetic vacuum fluctuations. However, to get the right spectral properties of the scattered light, it is essential to correctly describe the statistical properties of these vacuum fluctuations. Because of the presence of the two atoms, these statistical properties are not Gaussian : (i) the spatial two-points correlation function displays a speckle-like behavior and (ii) the three-points correlation function does not vanish. We also explain how to incorporate in a simple way propagation with a frequency-dependent scattering mean-free path, meaning that the two atoms are embedded in an average scattering dispersive medium. Finally we show that saturation-induced nonlinearities strongly modify the atomic scattering properties and, as a consequence, provide a source of decoherence in multiple scattering. This is exemplified by considering the coherent backscattering configuration where interference effects are blurred by this decoherence mechanism. This leads to a decrease of the so-called coherent backscattering enhancement factor.

description: The relative entropy between very high energy localized excitations and the vacuum, where both states are reduced to a spatial region, gives place to a precise definition of a local temperature produced by vacuum entanglement across the boundary. This generalizes the Unruh temperature of the Rindler wedge to arbitrary regions. The local temperatures can be read off from the short distance leading terms in the modular Hamiltonian. For free scalar and fermion fields they have a universal geometric expression that follows by solving a particular eikonal type equation in Euclidean space. This equation generalizes to any dimension the holomorphic property that holds in two dimensions. For regions of arbitrary shapes the local temperatures at a point are direction dependent. We compute their explicit expression for the geometry of a wall or strip.

description: We report the discovery of three binary millisecond pulsars during the Parkes Multibeam Pulsar Survey of the Galactic Plane. The objects are highly recycled and are in orbits of many tens of days about low-mass white-dwarf companions. The eccentricity of one object, PSR J1853+1303, is more than an order of magnitude lower than predicted by the theory of convective fluctuations during tidal circularization. We demonstrate that, under the assumption that the systems are randomly oriented, current theoretical models of the core-mass--orbital-period relation for the progenitors of these systems likely overestimate the white-dwarf masses, strengthening previous concerns about the match of these models to the data. The new objects allow us to update the limits on violation of relativistic equivalence principles to 95% confidence upper limits of 5.6 x 10^-3 for the Strong Equivalence Principle parameter Delta and 4.0 x 10^-20 for the Lorentz-invariance/momentum-conservation parameter alpha_3.

description: The diffractive photoproduction of rho mesons, e p \to e rho Y, with large momentum transfer squared at the proton vertex, |t|, is studied with the H1 detector at HERA using an integrated luminosity of 20.1 pb^{-1}. The photon-proton centre of mass energy spans the range 75 < W < 95 GeV, the photon virtuality is restricted to Q^2 < 0.01 GeV^2 and the mass M_Y of the proton remnant is below 5 GeV. The t dependence of the cross section is measured for the range 1.5 < |t| < 10.0 GeV^2 and is well described by a power law, dsigma/ d|t| \propto |t|^{-n}. The spin density matrix elements, which provide information on the helicity structure of the interaction, are extracted using measurements of angular distributions of the rho decay products. The data indicate a violation of s-channel helicity conservation, with contributions from both single and double helicity-flip being observed. The results are compared to the predictions of perturbative QCD models.

description: In this work we consider two possible wetting states for a droplet when placed on a substrate: the Fakir configuration of a Cassie-Baxter (CB) state with a droplet residing on top of roughness grooves and the Wenzel (W) state characterized by the homogeneous wetting of the surface. We extend a theoretical model based on the global interfacial energies for both states to study the wetting behavior of simple and double reentrant surfaces. Due to the minimization of the energies associated to each wetting state, we predict the thermodynamic wetting state of the droplet for a given surface and obtain its contact angle $θ_C$. We first use this model to find the geometries for pillared, simple and double reentrant surfaces that most enhances $θ_C$ and conclude that the repellent behavior of these surfaces is governed by the relation between the height and width of the reentrances. We compare our results with recent experiments and discuss the limitations of this thermodynamic approach. To address one of these limitations, we implement Monte Carlo simulations of the cellular Potts Model in three dimensions, allowing us to investigate the dependency of the wetting state on the initial state of the droplet. We find that when the droplet is initialized in a CB state, it gets trapped in a local minimum and stays in the repellent behavior irrespective of the theoretical prediction. When the initial state is W, simulations show a good agreement with theory for pillared surfaces, but for reentrant surfaces the agreement only happens in few cases: for most simulated geometries the contact angle reached by the droplet in simulations is higher than $θ_C$ predicted by the model. Moreover, we find that the contact angle of the simulated droplet is higher when placed on the reentrant surfaces than for a pillared surfaces with the same height, width and pillar distance.

description: We combine new narrow band photometry with archival WFPC2 data for A2218 ($z$=0.18) and A2125 ($z$=0.25), two clusters with intermediate redshifts but very different cluster properties, in order to examine the evolution of galaxy populations. A2218 is a dense, elliptical-rich cluster (Bautz-Morgan type II) similar to Coma in its evolutionary appearance; whereas, A2125 is a less dense, more open cluster (Bautz-Morgan type II-III), although similar in richness to A2218. The color-magnitude relation indicates that A2125 has a more developed blue population than A2218 (the Butcher-Oemler effect), although both clusters have significant numbers of blue galaxies (ranging in star formation rates from normal, star-forming disks to starburst systems) as compared to a present-day cluster. The colors of the red populations are identical in A2125 and A2218 and well fit by passive evolution models. We are able, for the first time, to combine archived WFPC2 images with our narrow band photometry for a color, morphological and structural analysis of the blue Butcher-Oemler population. We find the blue population to composed of two sub-populations, a bright, spiral population and a fainter, dwarf starburst population. A2125 is richer in bright starburst systems, apparently induced by the cluster's younger dynamical state. In addition, a majority of the S0 population in A2125 and A2218 is composed of bulge+disk systems, whereas, nearby clusters such as Coma are composed primarily of lenticulars (pure disk S0's). The structural parameters of the S0 bulges in A2125/A2218 are identical to the structure parameters of cluster ellipticals suggesting that the disks of some S0's in intermediate redshift clusters are stripped away with the leftover bulges evolving into present-day ellipticals.

description: We develop a sound and complete equational theory for the functional quantum programming language QML. The soundness and completeness of the theory are with respect to the previously-developed denotational semantics of QML. The completeness proof also gives rise to a normalisation algorithm following the normalisation by evaluation approach. The current work focuses on the pure fragment of QML omitting measurements.

description: Assuring transformative experiential learning through monitoring and evaluation Monitoring and evaluation (M&E) provides ways to engage educators in active learning and reflection (Mayana, 2020). By connecting M&E to the Theory of Change (ToC) it becomes possible to evaluate theories motivating programmes and initiatives working for social change. The ToC is focused not just on generating knowledge about whether an intervention is effective, but also on explaining what methods it uses to be effective and how the intervention will lead to expected intended outcomes (Vogel, 2012). Monitoring may be defined as “an ongoing process by which stakeholders obtain regular feedback on the progress being made towards goals and objectives. Monitoring is an important source of information for experiential learning evaluation. Evaluation is defined by Patton (2017) as “the systematic collection of information to make judgments, improve program effectiveness and/ or generate knowledge to inform decisions about future programs.” M&E leads to evidence-based decision-making which is critical for good governance and accountability within higher education (UNESCO, 2016). One of the main purposes of M&E in education is to ensure the provision of equitable and quality education for all. Quality education is a multi‐dimensional concept that takes into account the quality aspects on input (human, material, and financial), process (teaching‐learning and effective management practices), and outputs and outcomes (the learning outcomes and quality of results) (IIEP: 2007). These concepts are directly linked to the National Plan for Higher Education’s imperatives of access, success and redress (NPHE, 2012). The Co-curriculum Office recognises that M&E forms the bedrock of quality assurance in the design and implementation of sustainable education transformation initiatives (Cavanaugh, et.al., 2014). Furthermore, planning for M&E is considered one of the ten critical components needed to bring about a transformative student experience (Ibid). The Co-curriculum Office purposes to develop clear, attainable outcomes and goals for education transformation, and flexible strategies for achieving these. These goals are accomplished through ongoing communication with experiential educators regarding roles, expectations and progress, as well as documenting programmatic success and areas of potential enhancement. The Co-curriculum Office looks forward to sharing the findings of the 2019/2020 monitoring and evaluation process with the SOTL Conference participants.

description: We present measurements of CP-violating asymmetries and branching fractions for the decays omegapi+, omegaK+, and omegaK0. The data sample corresponds to 232 million BBbar pairs produced by e+e- annihilation at the Upsilon(4S) resonance. For the decay omegaKs, we measure the time-dependent CP-violation parameters S=0.51+0.35-0.39+/-0.02, and C=-0.55+0.28-0.26+/-0.03. We also measure the branching fractions, in units of 10^-6, B(omegapi+)=6.1+/-0.7+/-0.4, B(omegaK+)=6.1+/-0.6+/-0.4, and B(omegaK0)=6.2+/-1.0+/-0.4, and charge asymmetries Ach(omegapi+)=-0.01+/-0.10+/-0.01 and Ach(omegaK+)=0.05+/-0.09+/-0.01.

Information Complexity of Quantum Gates

description: This paper considers the realizability of quantum gates from the perspective of information complexity. Since the gate is a physical device that must be controlled classically, it is subject to random error. We define the complexity of gate operation in terms of the difference between the entropy of the variables associated with initial and final states of the computation. We argue that the gate operations are irreversible if there is a difference in the accuracy associated with input and output variables. It is shown that under some conditions the gate operation may be associated with unbounded entropy, implying impossibility of implementation.

description: Given a revived national discourse about rural populations, more educational research on rural students is necessary, including ways that rural students transition to college and the success (or lack thereof) that they experience once there. However, the National Center for Education Statistics (NCES) has changed the definition of rurality used in each iterative dataset over the last few decades, casting doubt on the consistency of what is meant by the term rural. The purpose of this study is to: (a) communicate to the educational research audience various ways of defining rural students, and specifically how NCES has changed their definition of rurality over their last three major data collections; (b) demonstrate how conclusions about rural students’ and their college degree completion may differ based on these alternate NCES definitions; and (c) discuss how this specific example using NCES data relates to the wider landscape of research on rural students. Results show that conclusions about college degree completion change depending on the definition of rurality used for analysis. Therefore, the education research community should consider the options for defining rural students, report transparently about the choices made, consider the sensitivity of results to the definition of rurality, and ultimately build a more robust body of literature concerning rural students’ college success. Gaining definitional clarity will be beneficial, particularly for those who wish to translate their research into practical action for the benefit of rural students.
GRB-supernovae: a new spin on gravitational waves

description: The discovery of the GRB-supernova association poses the question on the nature of the inner engine as the outcome of Type Ib/c supernovae. These events are believed to represent core-collapse of massive stars, probably in low-period stellar binaries and similar but not identical to the Type II event SN1987A. The branching ratio of Type Ib/c supernovae into GRB-supernovae has the remarkably small value of less than 0.5%. These observational constraints point towards a rapidly rotating black hole formed at low probability with low kick velocity. The putative black hole hereby remains centered, and matures into a high-mass object with large rotational energy in angular momentum. As the MeV-neutrino emissions from SN1987A demonstrate, the most powerful probe of the inner workings of core-collapse events are radiation channels to which the remnant envelope is optically thin. We here discuss the prospect of gravitational-wave emissions powered by a rapidly rotating central black hole which, in contrast to MeV-neutrinos, can be probed to distances as large as 100Mpc through upcoming gravitational-wave detectors LIGO and Virgo. We identify the GRB-emissions, commonly attributed to ultrarelativistic baryon-poor ejecta, with a new process of linear acceleration of charged particles along the axis of rotation of a black hole in response to spin-orbit coupling. We include some preliminary numerical simulations on internal shocks produced by intermittent ejecta. The results showing a radial splash, which points towards low-luminosity and lower-energy radiation at large angles, possibly related to X-ray flashes.

description: We present a measurement of the branching ratio of the CP violating decay KL->pi+pi- performed by the KLOE experiment at the phi factory DAFNE. We use 328 pb-1 of data collected in 2001 and 2002, corresponding to ~ 150 million tagged KL mesons. We find BR(KL->pi+pi-) = $(1.963 +/- 0.012 +/- 0.017)x 10^-3. This branching ratio measurement is fully inclusive of final-state radiation. Using the above result, we determine the modulus of the amplitude ratio |η_{+-}| to be (2.219 +/- 0.013)x 10^{-3} and |ε| to be (2.216 +/- 0.013)x 10^{-3}.

description: We propose a method for reconstruction of the optical potential from scattering data. The algorithm is a two-step procedure. In the first step the real part of the potential is determined analytically via solution of the Marchenko equation. At this point we use a diagonal Padé approximant of the corresponding unitary $S$-matrix. In the second step the imaginary part of the potential is determined via the phase equation of the variable phase approach. We assume that the real and the imaginary parts of the optical potential are proportional. We use the phase equation to calculate the proportionality coefficient. A numerical algorithm is developed for a single and for coupled partial waves. The developed procedure is applied to analysis of $^{1}S_{0}$ $NN$, $^{3}SD_{1}$ $NN$, $P31$ $π^{-} N$ and $S01$ $K^{+}N$ data.

Density-potential pairs for spherical stellar systems with Sersic light-profiles and (optional) power-law cores

description: Popular models for describing the luminosity-density profiles of dynamically hot stellar systems (e.g., Jaffe, Hernquist, Dehnen) were constructed with the desire to match the deprojected form of an R^{1/4} light-profile. Real galaxies, however, are now known to have a range of different light-profile shapes that scale with mass. Consequently, although highly useful, the above models have implicit limitations, and this is illustrated here through their application to a number of real galaxy density profiles. On the other hand, the analytical density profile given by Prugniel & Simien (1997) closely matches the deprojected form of Sersic R^{1/n} light-profiles - including deprojected exponential light-profiles. It is thus applicable for describing bulges in spiral galaxies, dwarf elliptical galaxies, and both ordinary and giant elliptical galaxies. Here we provide simple equations, in terms of elementary and special functions, for the gravitational potential and force associated with this density profile. Furthermore, to match galaxies with partially depleted cores, and better explore the supermassive black hole / galaxy connection, we have added a power-law core to this density profile and derived similar expressions for the potential and force of this hybrid profile. Expressions for the mass and velocity dispersion, assuming isotropy, are also given. These models may also prove appropriate for describing the dark matter distribution in halos formed from LCDM cosmological simulations.
