description: We numerically calculate the quasinormal frequencies of the Klein-Gordon and Dirac fields propagating in a two-dimensional asymptotically anti-de Sitter black hole of the dilaton gravity theory. For the Klein-Gordon field we use the Horowitz-Hubeny method and the asymptotic iteration method for second order differential equations. For the Dirac field we first exploit the Horowitz-Hubeny method. As a second method, instead of using the asymptotic iteration method for second order differential equations, we propose to take as a basis its formulation for coupled systems of first order differential equations. For the two fields we find that the results that produce the two numerical methods are consistent. Furthermore for both fields we obtain that their quasinormal modes are stable and we compare their quasinormal frequencies to analyze whether their spectra are isospectral. Finally we discuss the main results.

description: The non-perturbative quark-gluon interaction depends significantly on the value of the quark mass. In particular, in the light quark mass regime, correlations are strongly influenced by dynamics associated to chiral symmetry breaking. We use the Interacting Instanton Liquid Model (IILM) as a tool to investigate the microscopic dynamical mechanisms which underly the dependence on the quark mass and drive the transition into the chiral regime of QCD. To ensure the validity of the model, we first verify that the dependence on the quark mass for several observables calculated in the IILM agrees well with the predictions of chiral perturbation theory and with lattice simulations. We then show that a quark mass m*~80 MeV emerging naturally from the model specifies the mass scale above which the dynamics associated with low-lying eigenmodes of the Direac operator becomes sub-leading and the contribution of the fermion determinant is suppressed.

 More specimen of this species were collected on Citrus paradisi (Rutaceae) from Kilifi and Melia azadarach (Meliaceae) from Kisumu.
 Remarks: This species can be separated from the closely related E. africanus by the presence of only one seta on coxa II and an aedeagus whose bent portion is longer than the dorsal margin of the shaft (Figure 4 C).
 It has a wide distribution in the Afrotropical, Australasian and Palearctic regions as a pest of citrus. It has also been reported on members of other host families. In Kenya, this species was previously recorded on Citrus sp. (Rutaceae) from Thika district, Kenya (Meyer, 1987) and in this study it was collected from citrus trees in most of the areas where sampling was done. They are grey in colour and in cases of severe infestation, the plant appears dull in colour as though covered by a grey layer of soot.

description: Granular materials segregate spontaneously due to differences in particle size, shape, density and flow behaviour. In this paper we experimentally investigate density-difference-driven segregation for a range of density ratios and a range of heavy particle concentrations. The experiments are conducted in an annular shear cell with rotating bumpy bottom that yields an exponential shear profile. The cell is initially filled with a layer of light particles and an upper layer of heavier grains and, on top, a load provides confinement. The segregation process is filmed through the transparent side-wall with a camera, and the evolution of particle concentration in space and time is evaluated by means of post-processing image analysis. We also propose a continuum-approach to model density-driven segregation. We use a segregation-diffusion transport equation, constitutive relations for effective viscosity and friction coefficient, and a segregation velocity analogous to the Stokes' law. The model, which is validated by comparison with experimental findings, can successfully predict density-driven segregation at different density ratios and volumetric fraction.

description: In nominal mission scenarios, geostationary satellites perform end-of-life orbit maneuvers to reach suitable disposal orbits, where they do not interfere with operational satellites. This research investigates the long-term orbit evolution of decommissioned geostationary satellite under the assumption that the disposal maneuver does not occur and the orbit evolves with no control. The dynamical model accounts for all the relevant harmonics of the gravity field at the altitude of geostationary orbits, as well as solar radiation pressure and third-body perturbations caused by the Moon and the Sun. Orbit propagations are performed using two algorithms based on different equations of motion and numerical integration methods: (i) Gauss planetary equations for modified equinoctial elements with a Runge-Kutta numerical integration scheme based on 8-7th-order Dorman and Prince formulas; (ii) Cartesian state equations of motion in an Earth-fixed frame with a Runge-Kutta Fehlberg 7/8 integration scheme. The numerical results exhibit excellent agreement over integration times of decades. Some well-known phenomena emerge, such as the longitudinal drift due to the resonance between the orbital motion and Earth's rotation, attributable to the J22 term of the geopotential. In addition, the third-body perturbation due to Sun and Moon causes two major effects: (a) a precession of the orbital plane, and (b) complex longitudinal dynamics. This study proposes an analytical approach for the prediction of the precessional motion and shows its agreement with the orbit evolution obtained numerically. Moreover, long-term orbit propagations show that the above mentioned complex longitudinal dynamics persists over time scales of several decades. Frequent and unpredictable migrations toward different longitude regions occur, in contrast with the known effects due only to the J22 perturbation.

description: Dark magnetic spots crossing the stellar disc lead to quasi-periodic brightness variations, which allow us to constrain stellar surface rotation and photometric activity. The current work is the second of this series (Santos et al. 2019; Paper I), where we analyze the Kepler long-cadence data of 132,921 main-sequence F and G stars and late subgiant stars. Rotation-period candidates are obtained by combining wavelet analysis with autocorrelation function. Reliable rotation periods are then selected via a machine learning (ML) algorithm (Breton et al. 2021), automatic selection, and complementary visual inspection. The ML training data set comprises 26,521 main-sequence K and M stars from Paper I. To supplement the training, we analyze in the same way as Paper I, i.e. automatic selection and visual inspection, 34,100 additional stars. We finally provide rotation periods Prot and associated photometric activity proxy Sph for 39,592 targets. Hotter stars are generally faster rotators than cooler stars. For main-sequence G stars, Sph spans a wider range of values with increasing effective temperature, while F stars tend to have smaller Sph values in comparison with cooler stars. Overall for G stars, fast rotators are photometrically more active than slow rotators, with Sph saturating at short periods. The combined outcome of the two papers accounts for average Prot and Sph values for 55,232 main-sequence and subgiant FGKM stars (out of 159,442 targets), with 24,182 new Prot detections in comparison with McQuillan et al. (2014). The upper edge of the Prot distribution is located at longer Prot than found previously.

Further, we find sufficient conditions for bath-mediated entanglement generation in higher dimensional bipartite open quantum systems.

Parasites in primates : indicators of the host phylogeny
Creators: name: Glen, David Richard
Publisher: name: University of British Columbia
Year: 2010

description: The use of parasites to infer host relationships is well established. This thesis applies this concept to the parasites in catarrhine primates. Three catarrhine phylogenies are outlined, a 'troglodytian', a 'hylobatian' and a 'pongoian' hypothesis. The existence of these conflicting host phylogenies raises the possibility of using parasite data as an a priori tool to help choose between them. The central theme of this thesis is to see whether any one of the three primate phylogenies better explains the available parasitological evidence. Parasite data are of a different class than the data usually used to infer host relationships, and have thus been considered consilient. Two types of parasite data have been used to infer primate relationships. These include analyses of presence/absence checklists, and analyses of particular groups of parasites in primates. Both these types of data are featured in this thesis. The presence/absence data were analysed using a percentage calculation of shared parasites, and a phylogenetic protocol. The results of these analyses show that humans and cercopithee ids have the most parasites in common. Thus, this evidence can not be used to support any one of the three primate phylogenies outlined. With the exception of humans the presence/absence data support a coevolutionary pattern between primates and their helminth parasites. The divergence of humans from this pattern is the result of a number of host transfers to humans by parasites normally found in cercopithee ids. A phylogenetic analysis of twelve species in three subgenera of the hookworm genus Oesophagostomum is also presented. This analysis was based on twenty two characters and the overall c-index for the proposed phylogeny was 80%. The phylogeny of these parasites is more supportive of the 'troglodytian' primate hypothesis. This conclusion is however, dependant on the absence of a coevolved Oesophagostomum species in orangutans. Regardless of which primate phylogeny is correct the relationship between the Oesophagostomum species and primates appear to be predominantly coevolutionary. The biogeographic relationships between Oesophagostomum species and their hosts are also discussed. The support of the Oesophagostomum phylogeny for the 'troglodytian' hypothesis is in conflict with a previous study in which the pinworms (Enterobius) in primates were shown to support the 'hylobatian' primate hypothesis. These findings, along with the presence/absence results suggest that the parasite data at present do not support any one particular primate phylogeny. There are however, no parasite data supporting the 'pongoian' primate hypothesis.

description: We discuss topics related to finite-dimensional calculus in the context of finite-dimensional quantum mechanics. The truncated Heisenberg-Weyl algebra is called a TAA algebra after Tekin, Aydin, and Arik who formulated it in terms of orthofermions. It is shown how to use a matrix approach to implement analytic representations of the Heisenberg-Weyl algebra in univariate and multivariate settings. We provide examples for the univariate case. Krawtchouk polynomials are presented in detail, including a review of Krawtchouk polynomials that illustrates some curious properties of the Heisenberg-Weyl algebra, as well as presenting an approach to computing Krawtchouk expansions. From a mathematical perspective, we are providing indications as to how to implement in finite terms Rota's "finite operator calculus".

description: We report Coulomb drag measurements on GaAs-AlGaAs electron-hole bilayers. The two layers are separated by a 10 or 25nm barrier. Below T$\approx$1K we find two features that a Fermi-liquid picture cannot explain. First, the drag on the hole layer shows an upturn, which may be followed by a downturn. Second, the effect is either absent or much weaker in the electron layer, even though the measurements are within the linear response regime. Correlated phases have been anticipated in these, but surprisingly, the experimental results appear to contradict Onsager's reciprocity theorem.

description: The Sombrero galaxy (NGC 4594) is an Sa galaxy with a symmetric dust ring. We have used the Large APEX BOlometer CAmera (LABOCA) at 870 micron and the MAx-Planck Millimeter BOlometer (MAMBO-2) at 1.2 mm to detect the dust ring for the first time at submillimetre and millimetre wavelengths. We have constructed a model of the galaxy to separate the active galactic nucleus (AGN) and dust ring components. The ring radius at both 870 micron and 1.2 mm agrees well with the radius determined from optical absorption and atomic gas studies. The spectral energy distribution of the ring is well fitted by a single grey-body with dust emissivity index beta=2 and a dust temperature T_d=18.4 K. The dust mass of the ring is found to be 1.6\pm0.2x10^7Msun which, for a Galactic gas-to-dust ratio, implies a gas mass that is consistent with measurements from the literature.

Distinctive of this species are female dorsal opisthosomal setae which are set on tubercles, spiculate, do not taper, shorter than distances to next row of setae. Fourth pair of dorsocentrals (f1) nearer to each other than members of other three pairs of dorsocentrals.
Leg chaetotaxy as follows: tarsi 10(2)-9(1)-7-7; tibiae 9-5-5-5; genua 5-5-3-3; femora 7-6-3-2; coxae 2-2- 1-1.

 Remarks: This species has previously been reported in the Southern Africa region only. It was first described on Acacia karoo from South Africa (Ryke and Meyer, 1960) and has subsequently been collected on several species of Acacia. Although it is known to occur on hosts from other plants families, it seems to exhibit preference for the family Fabaceae. It is however found in small numbers and thus do not seem to cause any serious threat to the thorn trees. They are reddish brown in colour.

description: We discuss the physics of large impact parameter interactions at the LHC: ultraperipheral collisions (UPCs). The dominant processes in UPCs are photon-nucleon (nucleus) interactions. The current LHC detector configurations can explore small $x$ hard phenomena with nuclei and nucleons at photon-nucleon center-of-mass energies above 1 TeV, extending the $x$ range of HERA by a factor of ten. In particular, it will be possible to probe diffractive and inclusive parton densities in nuclei using several processes. The interaction of small dipoles with protons and nuclei can be investigated in elastic and quasi-elastic $J/ψ$ and $Υ$ production as well as in high $t$ $ρ^0$ production accompanied by a rapidity gap. Several of these phenomena provide clean signatures of the onset of the new high gluon density QCD regime. The LHC is in the kinematic range where nonlinear effects are several times larger than at HERA. Two-photon processes in UPCs are also studied. In addition, while UPCs play a role in limiting the maximum beam luminosity, they can also be used a luminosity monitor by measuring mutual electromagnetic dissociation of the beam nuclei. We also review similar studies at HERA and RHIC as well as describe the potential use of the LHC detectors for UPC measurements.

description: We study epicyclic oscillatory motion along circular geodesics of the Simpson--Visser meta-geometry describing in a unique way regular black-bounce black holes and reflection-symmetric wormholes by using a length parameter $l$. We give the frequencies of the orbital and epicyclic motion in a Keplerian disc with inner edge at the innermost circular geodesic located above the black hole outer horizon or on the our side of the wormhole. We use these frequencies in the epicyclic resonance version of the so-called geodesic models of high-frequency quasi-periodic oscillations (HF QPOs) observed in microquasars and around supermassive black holes in active galactic nuclei to test the ability of this meta-geometry to improve the fitting of HF QPOs observational data from the surrounding of supermassive black holes. We demonstrate that this is really possible for wormholes with sufficiently high length parameter $l$.

Stylisation et XVIIIème siècle. Etude de deux spectacles de F. Komissarževskij

description: L'articolo tratta di due spettacoli messi in scena da Fedor Komissarževskij, La reine de mai, un opera-pastorale di Gluck e la Locandiera di Goldoni, nel 1908-1909, epoca in cui in Russia si respirava  un'atmosfera simile a quella della Francia prerivoluzionaria. La maggior  parte dei registi dell'avanguardia teatrale tentava di superare il  'naturalismo' dell'arte drammatica di quel periodo soprattutto  attraverso lo studio delle tradizioni teatrali precedenti e la rilevanza  della scena rispetto all'attore - svutato ormai del suo ruolo di  protagonista. Komissarževskij, attraverso i due spettacoli anche se in  modo diverso, trovò una soluzione al principale problema del teatro  d'avanguardia: riuscì, cioè, a stilizzare il 'gioco' senza paralizzare  la creatività dell'attore.

description: Measurements of the critical current density (Jc) by magnetization and the upper critical field (Hc2) by magnetoresistance have been performed for hafnium-doped MgB2. There has been a remarkable enhancement of Jc as compared to that by ion irradiation without any appreciable decrease in Tc, which is beneficial from the point of view of applications. The irreversibility line extracted from Jc shows an upward shift. In addition, there has been an increase in the upper critical field which indicates that Hf partially substitutes for Mg. Hyperfine interaction parameters obtained from time differential perturbed angular correlation (TDPAC) measurements revealed the formation of HfB and HfB2 phases along with the substitution of Hf. A possible explanation is given for the role of these species in the enhancement of Jc in MgB2 superconductor.

Circe, i sofismi e le magie verbali. Nota a Plauto,  Epidicus 604
Creators: name: Franco, Cristiana
Publisher: name: Annali Online  Lettere - Ferrara
Year: 2013

description: In Epidicus 604 Periphanes insults Acropolistis, a dolosa fidicina who pretended to be his daughter, addressing her as a Circam, Solis filiam. According to Rigaltius, the main point of the insult lies in Solis filia, an expression that he interprets as meaning “daughter of unknown father”. Other scholars wonder whether the abuse alludes to Acropolostis’ ‘metamorphic’ powers; others hold that it stands, more generally, for “tricky courtesan”. However, in the scene that precedes the passage, Acropolistis’ ‘magic’ consists in a display of sophistic ‘fake logic’ and acrobatic rhetoric, for which Circe was likewise notorious in ancient times, as the entries παιπαλώδης and Κίρκη in Suida and Etymologicum Magnum clearly testify.

A New Catalog of Asymptotic Giant Branch Stars in Our Galaxy

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We present a new catalog of 11,209 O-rich AGB stars and 7172 C-rich AGB stars in our Galaxy identifying more AGB stars in the bulge component and considering more visual carbon stars. For each object, we cross-identify the IRAS, AKARI, MSX, WISE, 2MASS, and AAVSO counterparts. We present the new catalog in two parts: one is based on the IRAS PSC for brighter or more isolated objects; the other one is based on the ALLWISE source catalog for less bright objects or objects in crowded regions. We present various infrared two-color diagrams (2CDs) for the sample stars. We find that the theoretical dust shell models can roughly explain the observations of AGB stars on the various IR 2CDs. We investigate IR properties of SiO and OH maser emission sources in the catalog. For Mira variables in the sample stars, we find that the IR colors get redder for longer pulsation periods. We also study infrared variability of the sample stars using the WISE photometric data in the last 12 yr: the ALLWISE multiepoch data and the Near-Earth Object WISE Reactivation (NEOWISE-R) 2021 data release. We generate light curves using the WISE data at W1 and W2 bands and compute the Lomb-Scargle periodograms for all of the sample stars. From the WISE light curves, we have found useful variation parameters for 3710 objects in the catalog, for which periods were either known or unknown in previous works.

description: Petrified Girl Aglauros is quite a complex figure in Greek and Roman mythology: she is the daughter of Kekrops, the very one who was given the basket containing the baby Erichthonios by Athene and she is the one, with her sisters, Pandrosos and Herses, who disobeyed the goddess and opened the casket of Erichthonios. She sacrificed herself by leaping from Acropolis in order to save the city during a war, as well. For that reason, the Athenians made a hieron for her on Acropolis. In Ovid’s Metamorphosis (II 278ss.), she turned into a stone when refuses to open the door and let the god Hermes in as a suitor of her sister, Herse. This paper aims at focusing on the pattern of petrification by reading Aglauros myth as a story case: the stoning of Aglauros in not only the story of a punishment, but also a symbolic account of a very peculiar way of metarmophosis, the transformation of a female body into a dead block: i.e. the physiological transmigration of blood, water, body fluids into the stone. Female body and statue occupy two adjacent universes that alternate seamlessly in the myths of ancient heroines so that female bodies of parthenoi, of heroines, apparently share a sort of petrified nature after death.

description: Mononychellus progresivus Doreste, 1981
Female characterized by first to third pairs of dorsocentral setae (c1, d1 and e1) which are progressively longer towards rear, first pair about half as long as distances to bases of second pair; dorsal body setae generally long, setose and tapering but somewhat widened. Dorsal striations bear rounded lobes with basal spots. Aedeagus somewhat straight, narrowing distally to a relatively slender neck before ending in small angulations with anterior ventral angulation being acute and the distal dorsal one being very slightly curved.
Leg chaetotaxy as follows: tarsi 13+2-12+ 1-10-9; tibiae 9(1)-7-6-6; genua 5-5-4-3; femora 10-7-4-3; coxae 2-2-1-1.
 Specimens examined: 3 females and 1 male on Manihot esculenta (Euphorbiaceae) from Kabarnet, Baringo district (N00°27.785'; E035°45.722').
 Remarks: An earlier record of this species was reported by Girling et al. (1978) as Mononychellus tanajoa Bondar and later Guitterez (1987) reported that all the species from Africa earlier reported as Mononychellus tanajoa were infact Mononychellus progresivus. The host plant and specific location where this species was collected from in Kenya was not specified by the authors. This species is widespread in the tropics where Manihot esculenta is cultivated. It is likely that the pest spread with the spread of this crop to many tropical countries. This is one of the most important arthropod pests of Manihot esculenta and is amongst the spider mite species that are host specific since all the reports of this pest are from Manihot sp as a host plant. There have however been numerous debates on the identity of this species occurring in Africa with some authors insisting that the species that occur in cassava fields all over Africa is Mononychellus tanajoa Bondar and thus most publications that deal with its control and economic importance refer to Mononychellus tanajoa which has been successfully controlled using the phytoseiid mite Typhlodromalus aripo De Leon. However, comparing the features of the specimen I have with the description given by Meyer (1987) together with the paper by Guitterez (1987) show that our specimen correspond to the description of Mononychellus progressivus.
In the field, damaged leaves exhibit the typical silver stipples caused by spider mites and the species appears yellowish in colour.

description: Effect of short-range disorder on the excited states of the exciton is studied. Disorder causes an obvious effect of broadening. Microscopically, an exciton, as an entity, is scattered by the large-scale disorder fluctuations. Much less trivial is that short-scale fluctuations, with a period of the order of the Bohr radius, cause a well-defined down-shift of the exciton levels. We demonstrate that this shift exceeds the broadening parametrically and study the dependence of this shift on the orbital number. Difference of the shifts for neighboring levels leads to effective renormalization of the Bohr energy. Most remarkable effect is the disorder-induced splitting of S and P exciton levels. The splitting originates from the fact that disorder lifts the accidental degeneracy of the hydrogen-like levels. The draw an analogy between this splitting and the Lamb shift in quantum electrodynamics.

description: Dark matter (DM) decays and annihilations might heat and partially reionize the Universe at high redshift. Although this effect is not important for the cosmic reionization, the gas heating due to DM particles might affect the structure formation. In particular, the critical halo mass for collapse is increased up to a factor of ~2. Also the fraction of gas which collapses inside the smallest halos is substantially reduced with respect to the cosmological value. These effects imply that DM decays and annihilations might delay the formation of the first structures and reduce the total star mass in the smallest halos.

description: The lack of specialized personnel and assistive technology to assist in rehabilitation therapies is one of the challenges facing the health sector today, and it is projected to increase. For researchers and engineers, it represents an opportunity to innovate and develop devices that improve and optimize rehabilitation services for the benefit of society. Among the different types of injuries, hand injuries occur most frequently. These injuries require a rehabilitation process in order for the hand to regain its functionality. This article presents the fabrication and instrumentation of an end-effector prototype, based on a five-bar configuration, for finger rehabilitation that executes a natural flexion-extension movement. The dimensions were obtained through the gradient method optimization and evaluated through Matlab. Experimental tests were carried out to demonstrate the prototype's functionality and the effectiveness of a five-bar mechanism acting in a vertical plane, where gravity influences the mechanism's performance. Position control using fifth-order polynomials with via points was implemented in the joint space. The design of the end-effector was also evaluated by performing a theoretical comparison, calculated as a function of a real flexion-extension trajectory of the fingers and the angle of rotation obtained through an IMU. As a result, controlling the two degrees of freedom of the mechanism at several points of the trajectory assures the end-effector trajectory and therefore the fingers' range of motion, which helps for full patient recovery.
