Raphael at Court, but Not Altogether of It
Creators: name: Burroughs, Charles
Publisher: name: Iconocrazia
Year: 2023
Subjects: Stanze; Raphael; Andrea Mantegna; Baldassare Castiglione; Apollo; Parnassus

description: Raphael’s capacity to thrive at court stands out in an age of manners and reflections on manners. His reputation as a perfect courtier has been burnished by his association with Baldassare Castiglione, whose evocation of “the perfect courtier” was one of the most influential books of the Cinquecento and whose portrait by Raphael seems to embody the qualities outlined by Castiglione himself. Castiglione’s Book of the Courtier may represent a shift to self-conscious reflexivity in a long history of positive and negative writings on courts and courtiers. Nevertheless, it emerged in a culture used to visual representations of court life, from images of Mary as Queen of Heaven to more secular subjects, such as Mantegna’s Camera degli Sposi or Signorelli’s Court of Pan. In the Stanza della Segnatura, Raphael painted the court of Apollo on Parnassus with attendant beautiful women and talented and eloquent men (also women), as in Castiglione’s ideal court. Yet in the Stanza, there are indications of Raphael’s capacity for sly and witty subversion of the overarching epideictic purpose; in this, too, perhaps, he was a perfect courtier.

Orbital Periods and Waveforms of Dwarf Novae Observed by Kepler
Creators: name: Bruch, Albert
Publisher: name: arXiv
Year: 2021
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Kepler high cadence data are used to measure the orbital periods and to determine the orbital waveforms of five dwarf novae. A significant improvement of the period of V1504 Cyg is achieved, while for the other systems periods are derived which are compatible with previous determinations. The orbital waveforms of the short period systems V1504 Cyg, V344 Lyr and V516 Lyr are very nearly sinusoidal, while the longer period dwarf nova V447 Lyr appears almost to be a twin of U Gem. The unusual system KIC 9202990 exhibits distinct variations of its waveform as a function of brightness during its outburst cycle.
Titian’s Late St. Sebastian: Pestilence, Piety, Ineffable Emotion
Creators: name: Steele, Brian D.
Publisher: name: Iconocrazia
Year: 2023
Subjects: Titian; Saint Sebastian; non-finito concept; plague; Apollonian beauty; Christian iconography

description: Titian’s St. Sebastian (c.1570–1575) warrants sustained examination in view of the facts that the artist elected to formulate a distinctive mode of presentation vis-à-vis his previous versions of the subject and sufficiently finished principal portions of the image to establish essential concepts. David Rosand has elucidated the image’s paragone with antique sculpture; I expand investigation about heroic characterisation, an allusion to Apollonian beauty, and variations on sculptural prototypes by comparing iconographic examples and textual accounts of the saint. In particular, the saint’s striding stance intimates a narrative prolepsis that mitigates static representation as a bound martyr and amplifies resonant thematic conceits; close reading, in turn, facilitates scrutinising period conceptions within contexts of Sebastian as plague saint, Venetian political circumstances, and Christ-like sacrifice. Non-finito handling implies the artist’s immersion in representing this St. Sebastian, who presents an evolving image of the righteous character that, heedless of physicality, actively pursues things of greater glory. St. Sebastian incorporated implications of the divine origin attributed to the plague but evolved into a magnanimous exemplar of faith in redemption through Titian’s practice of inhabiting all emotions depicted.

description: We define a volume limited sample of over 14,000 early-type galaxies (ETGs) selected from data release six of the Sloan Digital Sky Survey. The density of environment of each galaxy is robustly measured. By comparing narrow band spectral line indices with recent models of simple stellar populations (SSPs) we investigate trends in the star formation history as a function of galaxy mass (velocity dispersion), density of environment and galactic radius. We find that age, metallicity and alpha-enhancement all increase with galaxy mass and that field ETGs are younger than their cluster counterparts by ~2 Gyr. We find negative radial metallicity gradients for all masses and environments, and positive radial age gradients for ETGs with velocity dispersion over 180 km/s. Our results are qualitatively consistent with a relatively simple picture for ETG evolution in which the low-mass halos accreted by a proto-ETG contained not only gas but also a stellar population. This fossil population is preferentially found at large radii in massive ETGs because the stellar accretions were dissipationless. We estimate that the typical, massive ETG should have been assembled at z < 3.5. The process is similar in the cluster and the field but occurred earlier in dense environments.

Francesco Salviati’s Emblematic Imagery in the Sala dell’Udienza of Florence
Creators: name: Cibelli, Deborah H.
Publisher: name: Iconocrazia
Year: 2023
Subjects: Sala dell’Udienza; Francesco Salviati; Paolo Giovio; fresco; symbolism

description: From 1543 to 1548, Francesco Salviati painted the fresco cycle depicting the triumph of the ancient Roman hero Marcus Furius Camillus in the Sala dell’ Udienza of the Palazzo Vecchio as the civic palace of the Florentine Republic was being transformed into a ducal residence for Cosimo I and his family. This study will focus on the emblematic imagery found in the dado or basamento of the audience hall. It will examine the depictions of the river gods in terms of ideas circulating among Salviati’s friends and associates, such as Paolo Giovio, the writer who shared an interest in allegorical images and emblems.

Jean-Étienne Liotard: The Rules of Art and the Late Still Life Paintings
Creators: name: Bell, Janice
Publisher: name: Iconocrazia
Year: 2023
Subjects: Liotard; still-life; rules of art; colour; light; Leonardo da Vinci

description: Jean-Étienne Liotard (Geneva 1702–1789) was renowned for his pastel portraits throughout Europe, but in his late years, he painted still lifes like Tea Set (c.1781–1783) in the J. Paul Getty Museum (Los Angeles). His short treatise Traité des principes et des règles de la peinture was penned in these years and sheds light on the shifting viewpoints that characterise his depiction, which departs from the strict, one-point perspective taught in art academies. The discussion here will focus on the deliberateness of this departure as an exploration of the role of colour and light in creating pictorial space, demonstrating principles that he articulated in his treatise.

description: We study the effects of realistic dephasing environments on a pair of solid-state single-photon sources in the context of the Hong-Ou-Mandel dip. By means of solutions for the Markovian or exact non-Markovian dephasing dynamics of the sources, we show that the resulting loss of visibility depends crucially on the timing of photon detection events. Our results demonstrate that the effective visibility can be improved via temporal post-selection, and also that time-resolved interference can be a useful probe of the interaction between the emitter and its host environment.

Discovering the Visual Legacy of Ginevra degli Amieri: From Chapbooks to Paul Richter’s Assessment of Hans Schäufelein’s Scenes from the Tale of Ginevra Degli Almieri and Antonio Rondinelli
Creators: name: Bates-Ehlert, Jennifer
Publisher: name: Iconocrazia

Subjects: cassoni; woodcuts; Amieri; Almieri; Schäufelein; Richter; Griselda; Mercato Vecchio; Florence

description:  Art historian Jean Paul Richter (1847–1937) is well known for his translations of Leonardo da Vinci’s notebooks and his role in framing art historical connoisseurship in the nineteenth century. However, his attributing the title Scenes from the Tale of Ginevra Degli Almieri and Antonio Rondinelli, a fifteenth-century Florentine legend, to a fifteenth-century German painting is problematic. This essay argues that Jean Paul Richter’s assessment of the panel is incorrect, offering, in conclusion, a field of further inquiry, Griselda, from Boccaccio’s Decameron, as the possible subject. To provide a visual comparison to the panel, this paper will examine woodcut prints included in sixteenth-century chapbooks of La Historia di Ginevra degli Almieri. The novella enjoyed a rediscovery among nineteenth-century British and American tourists, as the story’s setting—the medieval quarter of Florence near the Mercato Vecchio—had disappeared mainly due to Florence’s urban renewal programmes of the 1880s. For many, the destruction of this neighbourhood ripped out Florence’s heart, creating a renewed interest in the history of Florence’s medieval past. Ginevra’s legend struck a powerful chord, and countless writers and artists would translate, reprint, and paint her tale. The passion for Ginevra’s story may have influenced Richter’s assertion. Nonetheless, the panel’s dating of 1470 and visual inconsistencies between the painting and the novella create doubt about Richter’s assessment of the panel.

description: The short parton production phase in high-energy heavy-ion collisions is treated analytically as a nonlinear diffusion process. The initial buildup of the rapidity density distributions of produced charged hadrons within tau_p = 0.25 fm/c occurs in three sources during the colored partonic phase. In a two-step approach, the subsequent diffusion in pseudorapidity space during the interaction time of tau_int = 7-10 fm/c (mean duration of the collision) is essentially linear as expressed in the Relativistic Diffusion Model (RDM) which yields excellent agreement with the data at RHIC energies, and allows for predictions at LHC energies. Results for d+Au are discussed in detail.

description: The phase group and structure properties of La(Mg1/2Ti1/2)O3 (LMT) ceramics, prepared via the mixed oxide route, were examined in this research. A single-phase La(Mg1/2Ti1/2)O3 ceramic were produced at different sintering temperature from 1250ºC to 1675ºC. The heating rate was 25 ° C to the sintering temperature and the cooling rate from 2 ° C per minute to room temperature. The XRD analysis determined that LMT ceramics have a cubic crystal structure with a lattice parameter a = 0.392 nm. The theoretical density of this ceramics is 6.0846 g/cm3. These materials must be sintered from 1550- 1675°C to achieve a sintering density of about 99% of theoretical density. At a temperature lower than 1500°C a density was 93% of theoretical density. The temperature coefficient of resonant frequency for LMT was -72 ppm/ºC, and the Quality factor was 34000 at a frequency of 8.07 GHz

The presented modification of the scaling criterion resolves this problem. Also it is shown that the new criterion reproduces the main features of the scaling pictures for different cases of entangled states, while the previous versions lead to completely different outcomes. This property of the presented scheme is evidence of its higher generality.

Harmonising the Soul: Singing Laude for the Devotional Ascent
Creators: name: Powers, Katherine
Publisher: name: Iconocrazia
Year: 2023
Subjects: lauda (laude); Serafino Razzi; devotional music; devotional manuals; sermons

description: This essay discusses the work of Dominican Fra Serafino Razzi (1531–1611) as an advocate for singing for the devotions. While historians recognize Razzi’s critical contribution to the lauda (devotional songs in Italian) in the publication of his Libro primo delle laudi spirituali of 1563, less known are Razzi’s ideas on the integration of singing within the devotional ascent, in particular, the intention of laude singing as preparation for the mystic visio dei. Razzi was among the ‘most illustrious Dominicans’ in sixteenth-century Italy: a learned theologian with a humanist education, a confessor and preacher with a pastoral approach, and a prolific published author, including sermons and devotional manuals. Music occupied him throughout his long, industrious life: Razzi wrote about music, collected laude, and created new laude via the contrafact process, compiling six books of laude. His ideas echo Augustine, Boethius, Aquinas, and mystic Johannes Tauler. Sources for the paper include Razzi’s devotional works, sermons, and annotations to various laude within his lauda collections.

Normalisation for Bilateral Classical Logic with some Philosophical Remarks, and a Note on it

description: Bilateralists hold that the meanings of the connectives are determined by rules of inference for their use in deductive reasoning with asserted and denied formulas. This paper presents two bilateral connectives comparable to Prior's tonk, for which, unlike for tonk, there are reduction steps for the removal of maximal formulas arising from introducing and eliminating formulas with those connectives as main operators. Adding either of them to bilateral classical logic results in an incoherent system. One way around this problem is to count formulas as maximal that are the conclusion of reductio and major premise of an elimination rule and to require their removability from deductions. The main part of the paper consists in a proof of a normalisation theorem for bilateral logic. The closing sections address philosophical concerns whether the proof provides a satisfactory solution to the problem at hand and confronts bilateralists with the dilemma that a bilateral notion of stability sits uneasily with the core bilateral thesis. The Note corrects an error in one of the reduction steps in the paper.
Seeing Through the Turn of Sight: Jacopo Pontormo’s San Lorenzo Frescoes, the Roman Liturgy, and a Visionary Style

Publisher: name: Iconocrazia

Subjects: Bronzino; Pontormo; Choir of San Lorenzo; Certosa di Galluzo; Carthusian iconography; Roman Liturgy

description: For two hundred years, the frescoes Jacopo Pontormo (1494–1557) painted in the Florentine Church of San Lorenzo choir seemed to be among art history’s survivors. They survived the Reformation, the Counter-Reformation, and the dictates on art issued by the Council of Trent, which seemed to condemn them specifically. Long after art turned to earth hues, dimmed colours, dramatic chiaroscuro, and uncompromising realism, their glowing colours must have gleamed, almost reproachfully and certainly tauntingly at worshippers in the small church, promising a heavenly vision, conveyed through luxurious colours, that only the most devout could understand as the profoundly spiritual statement Pontormo intended. Still, they eventually fell before too pedestrian a view of spirituality. At San Lorenzo, in a moment of visionary inspiration, Pontormo sought to show the world what the mystics feel when they come into the presence of God. Guided by the texts of the Church, which mark its seasons and cycles into a liturgy of repetitive ritual knowledge and informed by the arguments of his time, Pontormo reached for the understanding that the Church gave to its true seers and mystics, who like Francis of Assisi and St. Teresa of Avila and St. Ignatius Loyola perceived without sight and knew without words what it was to be in the presence of divinity.

The Study of X-Ray Flux Variability of M87

Year: 2021
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We searched for a short-term X-ray variability of the M87 core and jet from archival X-ray data with long exposure data taken by the Suzaku, Chandra, and NuSTAR telescopes. We found the intraday variability for the Suzaku data obtained in 2006, and for the Chandra core obtained in 2017. The intraday variability suggested a minute emission region of about the size of Schwartzshild radius of the M87 supermassive black hole. Suzaku could not resolve a core and HST-1; however, in 2006, HST-1 was much brighter than the core, and thus, the variability is likely due to the HST-1. Since the photon index in 2006 was 2.38, the emission was possibly synchrotron emission from the local shock region in the HST-1, indicating that the particle acceleration of TeV electrons occurred far away (~100 pc) from the core. Assuming the fading time to be equal to the synchrotron cooling time, the magnetic field is constrained to be B ~1.94 $δ^{1/3}$ mG. Moreover, the photon index of the core in 2017 was approximately 1.96; thus, the possible emission was from the radiative inefficiency accretion flow of the core or inverse Compton scattering in the jet. Intraday time variability prefers the latter possibility.

description: Just as a rotating magnetised neutron star has material pulled away from its surface to populate a magnetosphere, a similar process can occur as a result of neutron-star pulsations rather than rotation. This is of interest in connection with the overall study of neutron star oscillation modes but with a particular focus on the situation for magnetars. Following a previous Newtonian analysis of the production of a force-free magnetosphere in this way Timokhin et al. (2000), we present here a corresponding general-relativistic analysis. We give a derivation of the general relativistic Maxwell equations for small-amplitude arbitrary oscillations of a non-rotating neutron star with a generic magnetic field and show that these can be solved analytically under the assumption of low current density in the magnetosphere. We apply our formalism to toroidal oscillations of a neutron star with a dipole magnetic field and find that the low current density approximation is valid for at least half of the oscillation modes, similarly to the Newtonian case. Using an improved formula for the determination of the last closed field line, we calculate the energy losses resulting from toroidal stellar oscillations for all of the modes for which the size of the polar cap is small. We find that general relativistic effects lead to shrinking of the size of the polar cap and an increase in the energy density of the outflowing plasma. These effects act in opposite directions but the net result is that the energy loss from the neutron star is significantly smaller than suggested by the Newtonian treatment.

description: We theoretically investigate possible photoinduced topological phase transitions in the organic salt $α$-(BEDT-TTF)$_2$I$_3$, which possesses a pair of inclined massless Dirac-cone bands between the conduction and valence bands under uniaxial pressure. The Floquet analyses of a driven tight-binding model for this material reveal rich photoinduced variations of band structures, Chern numbers, and Hall conductivities under irradiation with elliptically polarized light. The obtained phase diagrams contain a variety of nonequilibrium steady phases, e.g., the Floquet Chern insulator, Floquet semimetal, and Floquet normal insulator phases. This work widens a scope of target materials for research on photoinduced topological phase transitions and contributes to development of research on the optical manipulations of electronic states in matters.

Subjects: Christian iconography; Borghini; Bronzino; Dante; Razzi; Vasari; Santa Croce

description: In 1552, the Florentine painter and poet Agnolo Bronzino (1503–1572) was commissioned to paint Christ’s Descent into Limbo for the chapel of Giovanni Zanchini in Santa Croce in Florence. The painting draws inspiration from the Scriptures (Gospel of Nicodemus), Italian poets (Boccaccio, Petrarca, and Dante Alighieri), and the theological musician Fra Silvano Razzi. In Christ’s Descent into Limbo, Bronzino skilfully integrated portraits of Old Testament figures, ancient poets, and contemporary Florentine artists. Bronzino’s painting showcases his artistic talent by blending literary and visual components well, resulting in a captivating and profound work of art. Bronzino’s painting reveals his creative talent by masterfully combining literary and visual elements, resulting in beautiful and insightful artwork.
In this essay, I aim to delve into the characters’ identities depicted in the painting by analysing its iconography and comparing it with various sacred and profane texts. The essay comprises two sections: first, an examination of the painting’s iconography, and second, an analysis of the sources from Scripture, poetry, sermons, and religious music used to identify the characters in the painting.

description: The feast of the father is celebrated every year throughout Sicily on the onomastico or namesake of St. Joseph, beloved of Italy, on 19 March. In the small village of Scicli, situated on a vast plain in southeast Sicily’s Provincia di Ragusa, a splendid and spectacular cavalcade marks and memorialises St. Joseph’s Day, conjoined with the feast of the ‘Flight into Egypt.’ To unravel and understand the intricate ritual, cultural, and religious layers of this blended festival, we will examine the structure and dramaturgy of this cavalcade, with specific attention to the role of these holy beasts as they are ritually transformed into agents of the sacred drama of protection and flight. The horses are caparisoned with saddlecloths woven of thousands of flowers, tintinnabulating belled necklaces, and elaborate and regal feathered headdresses of about 4 feet high—all hand-made weeks before by the townspeople. Their sumptuous regalia mark them as the dramatis personae of this complex and ostentatious ceremony. This essay will illuminate the steps in this ritual parade and some of the long historical relationships between man and beast in Sicily’s quasi-liturgical ceremonies.

description: In quasi-persistent neutron star transients, long outbursts cause the neutron star crust to be heated out of thermal equilibrium with the rest of the star. During quiescence, the crust then cools back down. Such crustal cooling has been observed in two quasi-persistent sources: KS 1731-260 and MXB 1659-29. Here we present an additional Chandra observation of MXB 1659-29 in quiescence, which extends the baseline of monitoring to 6.6 yr after the end of the outburst. This new observation strongly suggests that the crust has thermally relaxed, with the temperature remaining consistent over 1000 days. Fitting the temperature cooling curve with an exponential plus constant model we determine an e-folding timescale of 465 +/- 25 days, with the crust cooling to a constant surface temperature of kT = 54 +/- 2 eV (assuming D=10 kpc). From this, we infer a core temperature in the range 3.5E7-8.3E7 K (assuming D=10 kpc), with the uncertainty due to the surface composition. Importantly, we tested two neutron star atmosphere models as well as a blackbody model, and found that the thermal relaxation time of the crust is independent of the chosen model and the assumed distance.

The latter is implemented by means of a modified momentum space Green's function. After calibrating the detector, we find that the net flux of field quanta is negligible, and that there is no Planckian spectrum. We discuss possible interpretations of this result, and we comment on experimental implications in heavy ion collisions and atomic systems.

description: TODO comments are very widely used by software developers to describe their pending tasks during software development. However, after performing the task developers sometimes neglect or simply forget to remove the TODO comment, resulting in obsolete TODO comments. These obsolete TODO comments can confuse development teams and may cause the introduction of bugs in the future, decreasing the software's quality and maintainability. In this work, we propose a novel model, named TDCleaner (TODO comment Cleaner), to identify obsolete TODO comments in software projects. TDCleaner can assist developers in just-in-time checking of TODO comments status and avoid leaving obsolete TODO comments. Our approach has two main stages: offline learning and online prediction. During offline learning, we first automatically establish training samples and leverage three neural encoders to capture the semantic features of TODO comment, code change and commit message respectively. TDCleaner then automatically learns the correlations and interactions between different encoders to estimate the final status of the TODO comment. For online prediction, we check a TODO comment's status by leveraging the offline trained model to judge the TODO comment's likelihood of being obsolete. We built our dataset by collecting TODO comments from the top-10,000 Python and Java Github repositories and evaluated TDCleaner on them. Extensive experimental results show the promising performance of our model over a set of benchmarks. We also performed an in-the-wild evaluation with real-world software projects, we reported 18 obsolete TODO comments identified by TDCleaner to Github developers and 9 of them have already been confirmed and removed by the developers, demonstrating the practical usage of our approach.
The Pierpont Morgan life and miracles of St. Edmund: some observations on the content and style of its illuminated miniatures
Creators: name: Fraser, Pamela Maria
Publisher: name: University of British Columbia
Year: 2010

description: This paper is concerned with a twelfth-century English manuscript, "The Life and Miracles of St. Edmund" (New York, Pierpont Morgan Library MS 736), and in particular with the thirty-two illuminated miniatures which decorate its opening pages. The manuscript is one of the two earliest surviving examples of an illustrated saint's Life made in England. It is also among the first English manuscripts to contain pictures painted in the Romanesque style. For these reasons, among others, the Morgan Life is a fascinating book to study. The first main section briefly discusses the physical details of the manuscript-- its content, organization, provenance, dating, authorship and function. The next section deals with the story of the saint and the development of his abbey in order to place the manuscript in its proper historical framework. Woven in with this is a discussion of the subject matter of the miniatures which attempts to answer the following questions: how do the illuminations relate to the text? does the choice of topics for illustration reflect the concerns and aspirations of Edmund's abbey? can the ideas and ideals exemplified by the pictorial narrative be connected with the thoughts and beliefs of Western society in the twelfth century? The final part of the paper undertakes an examination of the Morgan miniatures from a stylistic point of view. There is a continuing controversy among art historians concerning the authorship of the St. Edmund miniatures: some scholars suggest that the artist of the Morgan Life was the same man responsible for the paintings in the St. Albans Psalter-- the famous manuscript which introduced the Romanesque style to English illumination; other scholars hold different theories of authorship.

description: In general relativity, the instantaneous contributions to the gravitational potentials cancel each other in observable, leaving the theory free of physical instantaneous interactions. In models where these subtle cancellations are spoiled by the presence of fields that break Lorentz invariance, physical instantaneous interactions are possible. Such interactions are studied for a model of Lorentz- violating massive gravity.

description: Numerous fresh and saline-water tropical aquaculture ponds that often can be significant sources super-saturation of CO2 towards the atmosphere are gradually increasing throughout the world. The role of salinity in regulating the chlorophyll-a and dissolved pCO2 in a freshwater aquaculture pond, situated in East Kolkata Wetlands, Eastern India, was tested using a microcosm conducted during summer (April-May) and winter (December–January) months. The effects of enhanced salinity to microcosm sets of 5, 10 and 15 ppt were monitored for nine consecutive days. pH, dissolved oxygen (DO), pCO2(water), chlorophyll-a, and gross primary productivity (GPP) were measured in-situ and every day during the entire microcosm. Enhanced salinity was hypothesised to alter the pCO2(water) and chl-a dynamics of this system significantly. Increasing salinity to 5 ppt would enhance the photosynthetic potential of the existing primary producers and reduce the pCO2(water) significantly, thus boosting the CO2 sink strength. This enhanced CO2 sink strength, accompanied with increased GPP and DO, was also observed in 10 ppt, only during summer; however, low temperature was found to abate the photosynthetic response during winter. Finally, in 15 ppt treatments, drastic chlorophyll-a reduction and extreme CO2 super-saturation showed the existing phytoplankton community cannot cope with such high salinity.

description: The near-field of surface plasmons is locally confined to nanometer dimensions. Here, we use surface plasmons to initiate polymerfunctionalization of mesoporous silica films allowing subsequent ionic permselectivity gating based on polymer charge. We expect this functionalization approach to open a new dimension of functional miniaturization e.g. in nanofluidics.
The First Fermi Large Area Telescope Catalog of Gamma-ray Pulsars
Creators: name: Abdo, A. A.

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The dramatic increase in the number of known gamma-ray pulsars since the launch of the Fermi Gamma-ray Space Telescope (formerly GLAST) offers the first opportunity to study a population of these high-energy objects. This catalog summarizes 46 high-confidence pulsed detections using the first six months of data taken by the Large Area Telescope (LAT), Fermi's main instrument. Sixteen previously unknown pulsars were discovered by searching for pulsed signals at the positions of bright gamma-ray sources seen with the LAT, or at the positions of objects suspected to be neutron stars based on observations at other wavelengths. Pulsed gamma-ray emission was discovered from twenty-four known pulsars by using ephemerides (timing solutions) derived from monitoring radio pulsars. Eight of these new gamma-ray pulsars are millisecond pulsars. The pulsed energy spectra can be described by a power law with an exponential cutoff, with cutoff energies in the range 1 to 5 GeV. The rotational energy loss rate (\dot{E}) of these neutron stars spans 5 decades, from ~3x10^{33} erg/s to 5x10^{38} erg/s, and the apparent efficiencies for conversion to gamma-ray emission range from ~0.1% to unity, although distance uncertainties complicate efficiency estimates. The pulse shapes show substantial diversity, but roughly 75% of the gamma-ray pulse profiles have two peaks, separated by >0.2 of rotational phase. For most of the pulsars, gamma-ray emission appears to come mainly from the outer magnetosphere, while polar-cap emission remains plausible for a remaining few. Finally, these discoveries suggest that gamma-ray-selected young pulsars are born at a rate comparable to that of their radio-selected cousins and that the birthrate of all young gamma-ray-detected pulsars is a substantial fraction of the expected Galactic supernova rate.

description: We investigate two topics regarding solar mass FGK-type stars, the lithium rotation connection (LRC) and the existence of the "lithium desert". We determine the minimum critical rotation velocity ($v \sin i$) related with the LRC separating slow from rapid stellar rotators, as being 5 km s$^{-1}$. This value also split different stellar properties. For the first time we explore the behaviour of the LRC for some stellar associations with ages between 45 Myr and 120 Myr. This allows us to study the LRC age dependence at the beginning of the general spin down stage for low mass stars, which starts at $\sim$ 30-40 Myr. We find that each stellar group presents a characteristic minimum lithium (Li) depletion connected to a specific large rotation velocity and that this minimum changes with age. For instance, this minimum changes from $\sim$ 50 km s$^{-1}$ to less than 20 km s$^{-1}$ in 200 Myr. Regarding the lithium desert, it was described as a limited region in the A(Li)-$T_{\rm eff}$ map containing no stars. Using $T_{\rm eff}$ from {\em Gaia} DR2 we detect 30 stars inside and/or near the same box defined originally as the Li desert. Due to their intrinsic $T_{\rm eff}$ errors some of these stars may be inside or outside the box, implying a large probability that the box contains several stars. Considering this last fact the "lithium desert" appears to be more a statistical distribution fluctuation than a real problem.

description: The control of ionic permselectivity in porous films is an interesting aspect in the context of lab-on-chip devices and μ-electronics. Especially, visible light triggered ionic permselectivity control is of relevance because control by light can be maintained externally without changing internal system parameters. In addition, light is a sustainable energy source if sunlight is used. Here, we present the first mesoporous films modified with two different photochromic homopolymers by surface-initiated ring opening metathesis polymerization (SI-ROMP). Spiropyran- and spirooxazine functionalized norbornene monomers and the corresponding ROMP homopolymers are synthesized in solution and in mesopores and compared concerning their optical properties such as photochromic conversion kinetics, photostability, and the ratio of converted molecules. Optical properties are investigated using UV/VIS spectroscopy and 1H-NMR spectroscopy. Especially, spirooxazine, whose surface functionalization has not been studied in detail, shows fast switching properties and higher ratios of photochromically interconverted molecules. After grafting spiropyran- and spirooxazine norbornene homopolymers into mesopores, a slightly faster photochromic interconversion of polymers located inside the mesopores is observed compared to the solution polymers.

Un acercamiento a la poesía de Nicolas Guillén
Creators: name: Hillson, Richard Wayne
Publisher: name: University of British Columbia
Year: 2010

description: The poetry of Nicolás Guillén, Cuba's "poet of the Revolution", has been and continues to be a subject of much controversy. For a start, there are those who question his very status as a poet, claiming that the subject matter of his poetry is too "engagé" to qualify for the title of poetry, and consequently himself for the title of poet. Then, because he first made his mark on the world of poetry with a collection of poems with predominantly Mack motifs, he was automatically lumped into the Afro-Cubanist movement, very much in vogue at the time, as a result of which it has been generally felt that his poetry progressed from this "stage" of Afro-Cubanism to a "stage" of poetry of social awareness wherein his themes were either more meaningful, or less interesting, depending on the angle from which one cared to examine the poetry. Finally, Guillén has been accused of being a racist poet because of his evident bias and sympathy towards the African element in his Cuban society. The purpose of this thesis, without ever pretending to offer a definitive solution to the controversies, is to consider how far these opinions of his poetry are justifiable. Through a somewhat detailed examination of his poetry, especially his pre-1959 poetry (which is the poetry that did engender the controversies) I expect to show as far as it is possible that Guillén is a poet in his own right by demonstrating that his work contains all the elements that are generally considered to be the stuff of which poetry is made. I expect to show that there are no two "stages" in his poetry, and that his poetry is not racist, in spite of the extremely assertive manner the poet uses at times to present the African half of mulatto Cuba. In short, the thesis is an approach to the poetry of Nicolás Guillén, an attempt to shed some light on the problems surrounding it, a presentation of certain aspects that should, in my opinion, be considered in any evaluation of the poet's work.
