Luminosities of AGB Variables
Creators: name: Whitelock, Patricia
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The prevailing evidence suggests that most large-amplitude AGB variables follow the period luminosity (PL) relation that has been established for Miras in the LMC and galactic globular clusters. Hipparcos observations indicate that most Miras in the solar neighbourhood are consistent with such a relation. There are two groups of stars with luminosities that are apparently greater than the PL relation would predict: (1) in the LMC and SMC there are large amplitude variables, with long periods, P> 420 days, which are probably undergoing hot bottom burning, but which are very clearly more luminous than the PL relation (these are visually bright and are likely to be among the first stars discovered in more distant intermediate age populations); (2) in the solar neighbourhood there are short period, P<235 days, red stars which are probably more luminous than the PL relation. Similar short-period red stars, with high luminosities, have not been identified in the Magellanic Clouds.

description: We analyse the structural and dynamical properties of a sample of 324 nearby elliptical and dwarf elliptical galaxies observed during an extensive NIR survey in H-band (1.65 micron). The Fundamental Plane (FP) is determined and a significant tilt is assessed. The origins of such a tilt are investigated by means of a spherically symmetric, isotropic pressure supported dynamical model relying on the observed surface brightness profiles. The systematic variation of the shape coefficient converting the measured central velocity dispersion $ sigma_0$ into the virial rms velocity $ sigma_{rms}$ is found to be the main cause of the tilt, due to aperture effects. Moreover the ratio between the dynamical mass $M_{dyn}$ and the total H-band luminosity $L_H$ turns out to be roughly constant along the luminosity sequence of ellipticals: H-band luminosity is therefore a reliable and cheap estimator of the dynamical mass of the Es.

The contribution to the dephasing rate due to the bias depends on temperature and bias in the same way as shot-noise in the point contact at zero frequency, but do not follow the |t|^2(1-|t|^2) suppression.

title: The Effect of Impact Angle on the Secondary Droplets at High Impact Velocity

Publisher: name: Universitätsbibliothek Braunschweig
Year: 2019
Subjects: subject: splashing modeling, oblique impact, high Weber numbers, secondary droplets, size and velocity distributions
subject: 532

description: This study focuses on the secondary droplets ejected during splashing at different impact angles. We consider the
theory of Riboux & Gordillo [1], which attributes the generation of secondary droplets to a lift force that acts on the
spreading lamella, and propose a new approach to handle the oblique impact. This approach is based on previous
studies on the lamella formed by impinging jets, where the impacting flow is distributed in the azimuthal direction.
To validate the proposed method, we used a flywheel experiment and captured the secondary droplets that are
ejected at Weber number larger than 4500 at three different impact angles. In our experimental setup, the droplets
were formed by a droplet generator and then let to fall freely due to gravity until impacting the substrate, which
was mounted on a flywheel. The small and fast secondary droplets were captured using a shadowgraph technique
together with a high-resolution camera and Nd:YAG laser with diffuser optics. The experimental results showed an
acceptable agreement with the prediction made by our method in all studied cases. We demonstrate that the shape
and droplet size distribution are affected by the impact angle, while the velocity of the ejected droplets remains
constant in the azimuthal direction.

description: The interplay of electronic and nuclear degrees of freedom presents an outstanding problem in condensed matter physics and chemistry. Computational challenges arise especially for large systems, long time scales, in nonequilibrium, or in systems with strong correlations. In this work, we show how downfolding approaches facilitate complexity reduction on the electronic side and thereby boost the simulation of electronic properties and nuclear motion - in particular molecular dynamics (MD) simulations. Three different downfolding strategies based on constraining, unscreening, and combinations thereof are benchmarked against full density functional calculations for selected charge density wave (CDW) systems, namely 1H-TaS$_2$, 1T-TiSe$_2$, 1H-NbS$_2$, and a one-dimensional carbon chain. We find that the downfolded models can reproduce potential energy surfaces on supercells accurately and facilitate computational speedup in MD simulations by about five orders of magnitude in comparison to purely ab initio calculations. For monolayer 1H-TaS$_2$ we report classical replica exchange and quantum path integral MD simulations, revealing the impact of thermal and quantum fluctuations on the CDW transition.

description: Exact dynamical equations for a generic dust matter source field in a cosmological context are formulated with respect to a non-comoving Newtonian-like timelike reference congruence and investigated for internal consistency. On the basis of a lapse function $N$ (the relativistic acceleration scalar potential) which evolves along the reference congruence according to $\dot{N} = αΘN$ ($α= {const}$), we find that consistency of the quasi-Newtonian dynamical equations is not attained at the first derivative level. We then proceed to show that a self-consistent set can be obtained by linearising the dynamical equations about a (non-comoving) FLRW background. In this case, on properly accounting for the first-order momentum density relating to the non-relativistic peculiar motion of the matter, additional source terms arise in the evolution and constraint equations describing small-amplitude energy density fluctuations that do not appear in similar gravitational instability scenarios in the standard literature.

description: In Linear Logic ($\mathsf{LL}$), the exponential modality $!$ brings forth a distinction between non-linear proofs and linear proofs, where linear means using an argument exactly once. Differential Linear Logic ($\mathsf{DiLL}$) is an extension of Linear Logic which includes additional rules for $!$ which encode differentiation and the ability of linearizing proofs. On the other hand, Graded Linear Logic ($\mathsf{GLL}$) is a variation of Linear Logic in such a way that $!$ is now indexed over a semiring $R$. This $R$-grading allows for non-linear proofs of degree $r \in R$, such that the linear proofs are of degree $1 \in R$. There has been recent interest in combining these two variations of $\mathsf{LL}$ together and developing Graded Differential Linear Logic ($\mathsf{GDiLL}$). In this paper we present a sequent calculus for $\mathsf{GDiLL}$, as well as introduce its categorical semantics, which we call graded differential categories, using both coderelictions and deriving transformations. We prove that symmetric powers always give graded differential categories, and provide other examples of graded differential categories. We also discuss graded versions of (monoidal) coalgebra modalities, additive bialgebra modalities, and the Seely isomorphisms, as well as their implementations in the sequent calculus of $\mathsf{GDiLL}$.

description: It is one of the most important facts in 4-dimensional topology that not every spherical homology class of a 4-manifold can be represented by an embedded sphere. In 1978, M. Freedman and R. Kirby showed that in the simply connected case, many of the obstructions to constructing such a sphere vanish if one modifies the ambient 4-manifold by adding products of 2-spheres, a process which is usually called stabilisation. In this paper, we extend this result to non-simply connected 4-manifolds and show how it is related to the Spin^c-bordism groups of Eilenberg-MacLane spaces.

description: Various global characteristics of the coupling between the bound and scattering states are explicitly studied based on realistic Shell Model Embedded in the Continuum. In particular, such characteristics are related to those of the scattering ensemble. It is found that in the region of higher density of states the coupling to continuum is largely consistent with the statistical model. However, assumption of channel equivalence in the statistical model is, in general, violated.

description: The origin and nature of dark energy is one of the most significant challenges in modern science. This research aims to investigate dark energy on astrophysical scales and provide a cosmology-independent method to measure its equation-of-state parameter $w$. To accomplish this, we introduce the concept of a perfect fluid in any static, curved spacetime, and express the energy-momentum tensor of the perfect fluid in a general isotropic form, namely Weinberg's isotropic form. This enables us to define an equation-of-state parameter in a physical and global manner. Within this theoretical framework, we demonstrate that the energy-momentum tensor of dark energy on different scales can take the general isotropic form. Furthermore, we explore the SdS$_{w}$ spacetime and establish its connection with dark energy in cosmology through the equation-of-state parameter $w$. In the SdS$_{w}$ spacetime, a repulsive dark force can be induced by dark energy locally. We then apply the concept of the dark force to realistic astrophysical systems using the Poisson equation. Finally, we find that an anomaly in the Milky Way rotation curve can be quantitatively interpreted by the dark force. By fitting the galactic curve, we are able to obtain the value of the equation-of-state parameter of dark energy, independently of specific dark energy models.

Predictions of variable mass loss for Luminous Blue Variables
Creators: name: Vink, Jorick S.

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present radiation-driven wind models for Luminous Blue Variables (LBVs) and predict their mass-loss rates. We study the effects of lower masses and modified abundances in comparison to the normal OB supergiants, and we find that the main difference in mass loss is due to the lower masses of LBVs. In addition, we find that the increase in helium abundance changes the mass-loss properties by small amounts (up to about 0.2 dex in log Mdot), while CNO processing is relatively unimportant for the mass-loss rate. A comparison between our mass loss predictions and the observations is performed for four relatively well-studied LBVs. The comparison shows that (i) the winds of LBVs are driven by radiation pressure on spectral lines, (ii) the variable mass loss behaviour of LBVs during their S Doradus-type variation cycles is explained by changes in the line driving efficiency, notably due to the recombination/ionisation of Fe IV/III and Fe III/II, and finally, (iii) the winds of LBVs can be used to derive their masses, as exemplified by the case of AG Car, for which we derive a present-day mass of 35 Msun.

description: For a class of biped robots with impulsive dynamics and a non-empty set of passive gaits (unactuated, periodic motions of the biped model), we present a method for computing continuous families of locally optimal gaits with respect to a class of commonly used energetic cost functions (e.g., the integral of torque-squared). We compute these families using only the passive gaits of the biped, which are globally optimal gaits with respect to these cost functions. Our approach fills in an important gap in the literature when computing a library of locally optimal gaits, which often do not make use of these globally optimal solutions as seed values. We demonstrate our approach on a well-studied two-link biped model.

description: Motivated by the work of Whitt, who studied stabilization of the mean virtual waiting time (excluding service time) in a $GI_t/GI_t/1/FCFS$ queue, this paper investigates the stabilization of the mean virtual response time in a single-server processor sharing (PS) queueing system with a time-varying arrival rate and a service rate control (a $GI_t/GI_t/1/PS$ queue). We propose and compare a modified square-root (SR) control and a difference-matching (DM) control to stabilize the mean virtual response time of a $GI_t/GI_t/1/PS$ queue. Extensive simulation studies with various settings of arrival processes and service times show that the DM control outperforms the SR control for heavy-traffic conditions, and that the SR control performs better for light-traffic conditions.

description: Millions of people emigrate every year in search of better economic and social opportunities. Anecdotal evidence suggests that emigrants may have over-optimistic expectations about the incomes they can earn abroad, resulting in excessive migration pressure, and in disappointment amongst those who do migrate. Yet there is almost no statistical evidence on how accurately these emigrants predict the incomes that they will earn working abroad. In this paper we combine a natural emigration experiment with unique survey data on would-be emigrants' probabilistic expectations about employment and incomes in the migration destination. Our procedure enables us to obtain moments and quantiles of the subjective distribution of expected earnings in the destination country. We find a significant underestimation of both unconditional and conditional labor earnings at all points in the distribution. This under-estimation appears driven in part by potential migrants placing too much weight on the negative employment experiences of some migrants, and by inaccurate information flows from extended family, who may be trying to moderate remittance demands by understating incomes.

description: Cocoa (Theobroma cacao L.) is one of Indonesia's primary cash crops, supporting an estimated 900,000 households across the country. Smallholder farmers produce most of the crop, but their yields are about 50% of the potential yield. Fertilizer is known to increase cocoa yield. However, yield response to fertilizer application varies depending on the environmental conditions and management practices. There is limited information on the fertilizer requirements of mature cocoa genotypes commonly used in Indonesia. Therefore, an experiment on nitrogen, phosphorus, and potassium applications to hybrid cocoa trees was performed in Banyuwangi, East Java, Indonesia. Cocoa trees were planted on brown sandy podzolic soil. Coconut trees were used as a permanent shade with a density of 37 trees per hectare. The trial involved three N levels: 0, 93, and 186 kg/hectare/year; three P levels: 0, 80, and 160 kg/hectare/year and two K levels: 0 and 61 kg/hectare/year. Treatments were arranged in a factorial randomized block design with 3 replications. Fertilizer applications started 3 years after planting and were repeated every year. From year 3 to 22 after planting, the annual number of pods produced was counted and used to estimate dry bean yield per hectare. From 14 to 22 years after planting, a significant effect of the nitrogen application was observed on cocoa yield. Nitrogen fertilizer applied at 93 and 186 kg/hectare/year significantly increased dry bean yield per hectare by 16.8% and 17.1%, respectively, relative to control. However, there was no significant difference between both nitrogen fertilizer applications in their effect on yield. Although phosphorus and potassium fertilizers had been applied for 19 consecutive years, there was no response to these fertilizers over nine years of data, suggesting high phosphorus and potassium availability in the soil. The data suggest that hybrid cocoa planted on this typical brown sandy podzolic soil in Indonesia only requires nitrogen to sustain high productivity. Phosphorus and potassium fertilizers application are not required for cocoa trees planted on this typical soil type that return the pod husks to the plantation after harvesting.

description: We specify the semiclassical no-boundary wave function of the universe without relying on a functional integral of any kind. The wave function is given as a sum of specific saddle points of the dynamical theory that satisfy conditions of regularity on geometry and field and which together yield a time neutral state that is normalizable in an appropriate inner product. This specifies a predictive framework of semiclassical quantum cosmology that is adequate to make probabilistic predictions, which are in agreement with observations in simple models. The use of holography to go beyond the semiclassical approximation is briefly discussed.

Necessary and/or sufficient conditions of existence, uniqueness, and holonomicity of these bases in which the components of the derivations of the tensor algebra over it vanish on these subsets, are studied. The linear connections are considered in this context. It is shown that the equivalence principle is identically valid at any point, and along any path, in every gravitational theory based on linear connections. On higher dimensional submanifolds it may be valid only in certain exceptional cases.

description: We show that a minimal model for viscous fingering with a nematic liquid crystal in which anisotropy is considered to enter through two different viscosities in two perpendicular directions can be mapped to a two-fold anisotropy in the surface tension. We numerically integrate the dynamics of the resulting problem with the phase-field approach to find and characterize a transition between tip-splitting and side-branching as a function of both anisotropy and dimensionless surface tension. This anisotropy dependence could explain the experimentally observed (reentrant) transition as temperature and applied pressure are varied. Our observations are also consistent with previous experimental evidence in viscous fingering within an etched cell and simulations of solidification.

Biomimetic total synthesis of meroterpenoid natural products
Creators: name: Ma, Tsz Kan
Publisher: name: Imperial College London
Year: 2019

description: Meroterpenoids belong to a class of natural products that are biosynthesised via a mixed polyketide-terpenoid pathway. Meroterpenoids are reported to have a range of promising antibiotic, anti-tumor, anti-HIV and anti-diabetic activities. To fully evaluate their therapeutic potential, a concise and flexible synthetic route is required to access these natural products and their analogues for parallel syntheses to assist future bioassay and structure-activity relationship (SAR) studies. This thesis describes further developments and synthetic applications of the biomimetic polyketide aromatisation of β, σ-diketo dioxinones to produce resorcylates starting from commercially available terpene alcohols such as geraniol and trans, trans-farnesol. The resulting resorcylates are important intermediates which could be diversified into a selection of meroterpenoid natural products such as amorphastilbol, grifolic acid and grifolin via hydrolytic decarboxylation or saponification. Palladium catalysed oxidative cyclisation of resorcylates lead to the formation of chromene heterocycles to provide (±)-cannabiorcichromenic and (±)-daurichromenic acids. More complex polycyclic meroterpenoids such as the hongoquercins and the austalides could be accessed by subsequent cationic or radical anion polyene cyclisation.

description: In this paper we describe observations acquired by satellite instruments (Hinode/SOT and IRIS) and ground-based telescopes (ROSA@DST) during two consecutive C7.0 and X1.6 flares occurred in active region NOAA 12205 on 2014 November 7. The analysis of these data show the presence of continuum enhancements during the evolution of the events, observed both in ROSA images and in IRIS spectra. Moreover, we analyze the role played by the evolution of the $δ$ sunspots of the active region in the flare triggering, indicating the disappearance of a large portion of penumbra around these sunspots.

description: This article examines the features of knowledge gained through poetic creativity. Firstly, the theoretical considerations of Russian poet Olga Sedakova are reflected and, secondly, parallels to her literary work are demonstrated in an overview, but also based on a concrete analysis of one of her poems („Vzgljad kota“). It is shown that for Sedakova poetic creation leads to a form of knowledge, which she describes in terms of Goethe’s holistic view of science as a combination of conceptual and receptive capabilities, which enable us to reach metaphysical insights.

description: We describe an approach to the noncommutative instantons on the 4-sphere based on quantum group theory. We quantize the Hopf bundle S^7 --> S^4 making use of the concept of quantum coisotropic subgroups. The analysis of the semiclassical Poisson--Lie structure of U(4) shows that the diagonal SU(2) must be conjugated to be properly quantized. The quantum coisotropic subgroup we obtain is the standard SU_q(2); it determines a new deformation of the 4-sphere Sigma^4_q as the algebra of coinvariants in S_q^7. We show that the quantum vector bundle associated to the fundamental corepresentation of SU_q(2) is finitely generated and projective and we compute the explicit projector. We give the unitary representations of Sigma^4_q, we define two 0-summable Fredholm modules and we compute the Chern-Connes pairing between the projector and their characters. It comes out that even the zero class in cyclic homology is non trivial.

Numerical Study of a Superconducting Glass Model

description: An XY model with random phase shifts as a model for a superconducting glass is studied in two and three dimensions by a zero temperature domain wall renormalization group which allows one to follow the flows of both the coupling constant and the disorder strength with increasing length scale. Weak disorder is found to be marginal in two and probably irrelevant in three dimensions. For strong disorder the flow is towards a non-superconducting gauge glass fixed point in 2d and a superconducting glass in 3d. Our results are in agreement with recent analytic theory and are inconsistent with earlier predictions of a re-entrant transition to a disordered phase at very low temperature and with the loss of superconductivity for any finite amount of disorder.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

XMM-Newton and VLA Observations of the Variable Wolf-Rayet Star EZ CMa: Evidence for a Close Companion?

description: We present new X-ray and radio observations of the WR star EZ CMa (HD 50896) obtained with XMM-Newton and the VLA. This WN4 star shows optical/UV variability at a period of 3.76 d whose cause is unknown. VLA flux measurements at five frequencies show the radio spectral energy distribution is well-described by a power law with spectral index +0.69 (+-0.05), as expected for free-free wind emission. The derived ionized mass loss rate allowing for distance uncertainties is M(dot) = 3.8 (+-2.6)e-5 M_sun/yr. The CCD X-ray spectra show prominent Si XIII and S XV emission lines and can be acceptably modeled as an absorbed multi-temperature optically thin plasma. Nonsolar abundances are inferred with Fe notably deficient. The X-ray emission is dominated by cool plasma at kT_cool = 0.6 keV, but a harder component is also detected with a derived temperature kT_hot = 3.0 - 4.2 keV if the emission is thermal. This is too high to be explained by radiative wind shock models and the luminosity of the hard component is 3 orders of magnitude lower than expected for accretion onto a neutron star companion. We argue that the hard emission could be produced by the WR wind shocking onto a normal (nondegenerate) stellar companion at close separation. Using comparable data sets, we show that the X-ray and radio properties of EZ CMa are strikingly similar to those of the WN5-6 star WR110. This similarity points to common X-ray and radio emission processes in WN stars and discredits the idea that EZ CMa is anomalous within its class.

Severe nausea and vomiting (hyperemesis gravidarum): psychological impact and current management
Creators: name: Mitchell-Jones, Nicola
Publisher: name: Imperial College London
Year: 2018

description: This thesis comprises three studies with the combined aim of improving care for women with hyperemesis gravidarum (HG), a severe form of nausea and vomiting of pregnancy (NVP). The first component of the thesis was a randomised control trial (RCT) of inpatient versus outpatient management of HG. The aim was to determine whether outpatient (ambulatory) management (whereby women could stay at home with family between treatment episodes) was of equal efficacy to standard inpatient management. The methodology of the trial was adapted due to strong patient preferences within the study group. The RCT with patient preference arm found that ambulatory care was as effective as inpatient management of HG. The second and third components of the thesis focused on the psychological and psychosocial aspects of HG. A systematic review and meta-analysis assessing the relationship between HG and psychological symptoms was undertaken in which 12 case-control papers were meta-analysed. A very large effect between HG and depression and a large effect between HG and anxiety were found. A two-point case control study was then undertaken to assess psychological symptoms, hospital experience, infant bonding and psychosocial experiences in women with HG compared to two control groups (one asymptomatic and the other admitted to hospital for other symptoms). Women completed survey assessments both during and after pregnancy. The study found that HG significantly increased the risk of major depressive disorder during and after pregnancy, women with HG had more negative experiences of hospital care and significantly more psychosocial sequelae were reported during pregnancy. Infant bonding was not directly affected. In conclusion, the work of this thesis has provided strong evidence which can be utilised to improve care for women suffering from HG, beyond the current standard supportive medical care of physical symptoms

description: Many systems can display a very short, rapid changing stage (quasi-discontinuous region) inside a relatively very long and slowly changing process. A quantitative definition for the "quasi-discontinuity" in these systems has been introduced. We have shown by a simplified model that extra-large Feigenbaum constants can be found inside some period-doubling cascades due to the quasi-discontinuity. As an example, this phenomenon has also been observed in Rose-Hindmash model describing neuron activities.
