Finite element modeling of frictional contact and stress intensity factors in three-dimensional fractured media using unstructured tetrahedral meshes
Creators: name: Nejati, Morteza
Publisher: name: Imperial College London
Year: 2015

description: This thesis introduces a three-dimensional (3D) finite element (FE) formulation to model the linear elastic deformation of fractured media under tensile and compressive loadings. The FE model is based on unstructured meshes using quadratic tetrahedral elements, and includes several novel components: (i) The singular stress field near the crack front is modeled using quarter-point tetrahedral finite elements. (ii) The frictional contact between the crack faces is modeled using isoparametric contact discretization and a gap-based augmented Lagrangian method. (iii) Accurate stress intensity factors (SIFs) of 3D cracks computed using the two novel approaches of displacement correlation and disk-shaped domain integral. The main contributions in the FE modeling of 3D cracks are: (i) It is mathematically proven that quarter-point tetrahedral finite elements (QPTs) reproduce the square root strain singularity of crack problems. (ii) A displacement correlation (DC) scheme is proposed in combination with QPTs to compute SIFs from unstructured meshes. (iii) A novel domain integral approach is introduced for the accurate computation of the pointwise $J$-integral and the SIFs using tetrahedral elements. The main contributions in the contact algorithm are: (i) A square root singular variation of the penalty parameter near the crack front is proposed to accurately model the contact tractions near the crack front. (ii) A gap-based augmented Lagrangian algorithm is introduced for updating the contact forces obtained from the penalty method to more accurate estimates. The results of contact and stress intensity factors are validated for several numerical examples of cubes containing single and multiple cracks. Finally, two applications of this numerical methodology are discussed: (i) Understanding the hysteretic behavior in rock deformation; and (ii) Simulating 3D brittle crack growth. The results in this thesis provide significant evidence that tetrahedral elements are efficient, reliable and robust instruments for accurate linear elastic fracture mechanics calculations.

The Effects of Substructure on Galaxy Cluster Mass Determinations
Creators: name: Bird, Christina M.
Publisher: name: arXiv
Year: 1995
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Although numerous studies of individual galaxy clusters have demonstrated the presence of significant substructure, previous studies of the distribution of masses of galaxy clusters determined from optical observations have failed to explicitly correct for substructure in those systems. In this {\it Letter} I present the distributions of velocity dispersion, mean separation, and dynamical masses of clusters when substructure is eliminated from the cluster datasets. I also discuss the changes in these distributions because of the substructure correction. Comparing the masses of clusters with central galaxies before and after correction for the presence of substructure reveals a significant change. This change is driven by reductions in the mean separation of galaxies, not by a decrease in the velocity dispersions as has generally been assumed. Correction for substructure reduces most significantly the masses of systems with cool X-ray temperatures, suggesting that the use of a constant linear radius (1.5$h _{100} ^{-1}$ Mpc in this study) to determine cluster membership is inappropriate for clusters spanning a range of temperatures and/or morphologies.

Heterodimensional cycles near homoclinic bifurcations
Creators: name: Li, Dongchen
Publisher: name: Imperial College London
Year: 2016

description: In this thesis we study bifurcations of a pair of homoclinic loops to a saddle-focus equilibrium (with a one-dimensional unstable manifold) in flows with dimension four or higher. Particularly, we show that heterodimensional cycles can be born from such bifurcations. A heterodimensional cycle consists of two saddle periodic orbits having different indices (dimensions of unstable manifolds), and two heteroclinic connections between those orbits. We find heterodimensional cycles for the flow as the suspension of heterodimensional cycles for a Poincaré map around the homoclinic loops. Especially, those cycles are co-index 1, i.e. the difference between indices is 1. More specifically, each of those heterodimensional cycles are associated to periodic orbits of indices 2 and 3. As a partial result we mention a criterion for having index 3 for periodic orbits near a homoclinic loop to a saddle-focus equilibrium. Different types of perturbations are considered, where the original homoclinic loops can be either kept or split. In intermediate steps we find, in addition to the classical heterodimensional connection between two periodic orbits, two new types of heterodimensional connections: one is a heteroclinic between a homoclinic loop and a periodic orbit of index 2, and the other connects a saddle-focus equilibrium to a periodic orbit of index 3. Furthermore, we consider a symmetric case where the codimension of the bifurcations is minimised to 1. We prove that, by endowing the flow with a certain $\mathbb{Z}_2$ symmetry, a pair of heterodimensional cycles can be born from a one-parameter unfolding of the symmetric pair of homoclinic loops. Moreover, we show that the heterodimensional cycles obtained in either the general or the symmetric case can belong to a chain-transitive and volume-hyperbolic attractor of the flow, along with a persistent homoclinic tangency.

description: A two-dimensional (2D) harmonically trapped interacting Fermi gas is anticipated to exhibit a quantum anomaly and possesses a breathing mode at frequencies different from a classical scale invariant value $ω_{B}=2ω_{\perp}$, where $ω_{\perp}$ is the trapping frequency. The predicted maximum quantum anomaly ($\sim10\%$) has not been confirmed in experiments. Here, we theoretically investigate the zero-temperature density equation of state and the breathing mode frequency of an interacting Fermi superfluid at the dimensional crossover from three to two dimensions. We find that the simple model of a 2D Fermi gas with a single $s$-wave scattering length is not adequate to describe the experiments in the 2D limit, as commonly believed. A more complete description of quasi-2D leads to a much weaker quantum anomaly, consistent with the experimental observations. We clarify that the reduced quantum anomaly is due to the significant confinement-induced effective range of interactions, which is overlooked in previous theoretical and experimental studies.
description: 5 pages, 4 figures; resubmitted version; the title is changed to emphasize that the experimentally observed reduced quantum anomaly is due to a large effective range of interactions at the current experimental conditions

Comprehensive macroseismic analyses for probabilistic seismic hazard assessment in intraplate regions
Creators: name: Han, Jeongmin
Publisher: name: Imperial College London
Year: 2016

description: In low to moderate seismicity intraplate regions, earthquake engineers and engineering seismologists face challenges dealing with the considerable level of uncertainty in the estimation of magnitude recurrence parameters and maximum magnitude estimation for probabilistic seismic hazard assessment (PSHA). This is largely due to the lack of strong ground motion records, short and incomplete earthquake catalogue, and extremely long recurrence intervals between large magnitude events. This puts additional importance of finding reliable estimates of earthquake source parameters for historical and early instrumental records which often have greater impact on hazard results than short span of instrumental records. This thesis explores the presence of regional differences within stable continental regions (SCRs) as well as a degree of regional variability with respect to the global average SCR using isoseismal area data. This is accomplished by careful collection and processing of isoseismal areas from the global stable continental regions, and by developing felt area-to-magnitude relationships through a uniform regression framework of Johnston (1996b). By comparing with existing relationships, the applicability of the newly developed felt area-to-magnitude relationships is evaluated. Analyses of focal depth distribution, and their correspondence with the Moho depth and the surface heat flow are investigated for the Korean peninsula, as a case study region. Macroseismic attenuation parameters for the Kövesligethy (1906) attenuation model are derived from a newly compiled, comprehensive macroseismic intensity database in order to determine macroseismic focal depths. The influence of using different types of macroseismic data and regional earthquake data on the macroseismic attenuation parameters is also investigated. Finally, a suite of three intensity attenuation models, each using a different functional form, is derived for the Korean peninsula, and the sensitivity of the model results to different regression techniques and functional regression forms is evaluated. The newly derived intensity attenuation model is used to estimate earthquake magnitude and epicentral location through the bootstrap resampling technique of Bakun and Wentworth (1997).

The role of melanocortin pathways in the mesocorticolimbic system in the regulation of energy Homeostasis
Creators: name: Banks, Katherine Anne
Publisher: name: Imperial College London
Year: 2015

description: The increasing worldwide incidence of obesity presents a significant economic burden on healthcare resources. The recent obesity epidemic may be attributed to the increasing availability of high fat and high sugar foods in our modern environment. These foods are energy dense, and are thus processed by the mesocorticolimbic system as rewarding substrates. The increased hedonic experience encoded by the activation of the mesocorticolimbic system during consumption of these energy dense foods may result in overconsumption. This may result in non-homeostatic energy intake, precipitating obesity. Melanocortins are neuropeptides which signal anorectically to reduce food intake and increase energy expenditure. Preliminary data within our group found that intra-ventral tegmental area (VTA) melanocortin administration reduced acute food intake in ad libitum fed rats. The work described in this thesis has determined that this effect is mediated via the melanocortin 4 receptor (MC4R), and is dependent on both nutritional status and diurnal phase. Furthermore, melanocortins were found to reduce acute food seeking behaviour in mice. Intra-VTA administration of melanocortins resulted in the increased activation of neurons in both the VTA and downstream mesocorticolimbic areas, including the nucleus accumbens shell, amygdala, lateral septal nuclei, ventral pallidum (VP) and the prefrontal cortex. Finally, the restoration of MC4R signalling in specific regions of the mesocorticolimbic system of MC4R null mice was used to investigate the role of MC4R in reward and energy homeostasis. Restoring MC4R signalling in the VP decreased chronic food intake but had no effect on body weight. General activity was decreased in these mice, suggesting melanocortin signalling in the VP plays a role in activity and energy expenditure. These findings suggest that melanocortin signalling in the mesocorticolimbic system may serve to maintain energy homeostasis and thus prevent the development of obesity. Further work is required to characterise the specific neuronal circuits responsible.
Speech enhancement in the modulation domain
Creators: name: Wang, Yu
Publisher: name: Imperial College London
Year: 2015

description: The goal of a speech enhancement algorithm is to reduce or eliminate background noise without distorting the speech signal. Although speech enhancement is important for practical scenarios, it is a difficult task especially when the noisy speech signal is only available from a single channel. Although many single-channel speech algorithms have been proposed that can improve the Signal-to-Noise Ratio (SNR) of the noisy speech, in some cases dramatically, they also introduce speech distortion and spurious tonal artefacts known as musical noise. There has been evidence, both physiological and psychoacoustic, to support the significance of the modulation domain, i.e. the temporal modulation of the acoustic spectral components, to speech enhancement. In this thesis three methods for implementing single-channel speech enhancement in the modulation domain have been proposed. The goal in all three cases is to take advantage of prior knowledge about the temporal modulation of short-time spectral amplitudes. The first method is to post-process the output of a conventional single-channel speech enhancement algorithm using a modulation domain Kalman filter. The second method performs enhancement directly in the modulation domain based on the assumption that the temporal sequence of spectral amplitudes within each frequency bin lies within a low dimensional subspace. The third method uses a modulation-domain Kalman filter to perform enhancement using two alternative distribution families for the speech and noise amplitude prior distributions. The performance of the proposed enhancement algorithms is assessed by measuring the SNR and speech quality (using the Perceptual Evaluation of Speech Quality (PESQ) metric) of the enhanced speech. It is found that, for a range of noise types, the proposed algorithms give consistent improvements in both metrics.

The Baryonic Mass Function of Spiral Galaxies: Clues to Galaxy Formation
Creators: name: Salucci, P.

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)

description: We compute the baryonic mass function (BMF) of disc galaxies using the best LFs and baryonic M/L ratios reliable for this goal. For baryonic masses (M_b) ranging between 10^8 and 10^{11} solar masses, the BMF is featureless, i.e. it scales as M_b^{-1/2}. Outside this mass range, the BMF is a strong inverse function of M_b. The contributions to the baryon density Omega_b from objects of different mass highlight a characteristic mass scale of spirals at about 2x10^{11} solar masses, around which >50% of the total baryonic mass is concentrated. The integral value, Omega_b= 1.4x10^{-3}, confirms, to a higher accuracy, previous evidence (Persic & Salucci 1992) that the fraction of BBN baryons locked in disc galaxies is negligible and matches that of high-z Damped Lyman Alpha systems (DLAs). We investigate the scenario where DLAs are the progenitors of present-day spirals, and find a simple relationship between their masses and HI column densities by which the DLA mass function closely matches the spiral BMF.

A Nested Grid Particle-Mesh Code for High Resolution Simulations of Gravitational Instability in Cosmology

Year: 1995
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I describe a nested-grid particle-mesh (NGPM) code designed to study gravitational instability in three-dimensions. The code is based upon a standard PM code. Within the parent grid I am able to define smaller sub-grids allowing us to substantially extend the dynamical range in mass and length. I treat the fields on the parent grid as background fields and utilize a one-way interactive meshing. Waves on the coarse parent grid are allowed to enter and exit the subgrid, but waves from the subgrid are precluded from effecting the dynamics of the parent grid. On the parent grid the potential is computed using a standard multiple Fourier transform technique. On the subgrid I use a Fourier transform technique to compute the subgrid potential at high resolution. I impose quasi-isolated boundary conditions on the subgrid using the standard method for generating isolated boundary conditions, but rather than using the isolated Green function I use the Ewald method to compute a Green function on the subgrid which possesses the full periodicity of the parent grid. I present a detailed discussion of my methodology and a series of code tests.

description: We introduce a class of F-theory vacua which may be viewed as a specialization of the so-called $E_6$ fibration, and construct a weak coupling limit associated with such vacua which we view as the `square' of the Sen limit. We find that while Sen's limit is naturally viewed as an orientifold theory, the universal tadpole relation which equates the D3 charge between the associated F-theory compactification and the limit we construct suggests that perhaps the limiting theory is in fact an oriented theory compactified on the base of the F-theory elliptic fibration.

Defining the calcineurin-dependent innate immune response of human alveolar macrophages to Aspergillus fumigatus
Creators: name: Shah, Anand
Publisher: name: Imperial College London
Year: 2016

description: Pulmonary aspergillosis is a lethal mould infection in the immunocompromised host. Understanding initial control of infection, and how this is altered in the immunocompromised host, is a key goal for understanding the pathogenesis of pulmonary aspergillosis. My thesis aims to characterise the outcome of human macrophage infection with Aspergillus fumigatus, and understand how this is altered in transplant recipients on calcineurin inhibitor immunosuppressants. I initially quantified the impact of calcineurin inhibitors on fungal killing following in vitro human alveolar macrophage infection with A. fumigatus. A human monocyte-derived macrophage model was then used to systematically analyse calcineurin-dependent effects on phagocytosis, phagosomal maturation, reactive oxygen species and cytokine production. Calcineurin-dependent mechanisms of fungal killing were then further characterised by a combination of single cell fluorescence imaging, proteomics, and in vivo studies. Human alveolar macrophage killing of A. fumigatus is calcineurin-dependent. Macrophage phagocytosis of A. fumigatus enabled control of 90% of fungal germination. However fungal germination in the late phagosome led to macrophage necrosis. During programmed necrosis, I observed frequent cell-cell transfer of A. fumigatus between macrophages which assists subsequent control of germination in recipient macrophages. Lateral transfer occurred through actin-dependent exocytosis of the late endosome in a vasodilator-stimulated phosphoprotein (VASP) envelope. Its relevance to the control of fungal germination was also shown by direct visualisation in a zebrafish aspergillosis model in vivo. The calcineurin inhibitor FK506/tacrolimus reduced cell death and lateral transfer in vitro by 50%. This resulted in uncontrolled fungal germination in macrophages and hyphal escape. This thesis identifies programmed necrosis-dependent lateral transfer of A. fumigatus between macrophages as an important host strategy for controlling fungal germination. This process is critically dependent on calcineurin. This provides fundamental insights into the pathogenesis of pulmonary aspergillosis in the immunocompromised host.

description: We consider fast deterministic algorithms to identify the "best" linearly independent terms in multivariate mixtures and use them to compute, up to a user-selected accuracy, an equivalent representation with fewer terms. One algorithm employs a pivoted Cholesky decomposition of the Gram matrix constructed from the terms of the mixture to select what we call skeleton terms and the other uses orthogonalization for the same purpose. Importantly, the multivariate mixtures do not have to be a separated representation of a function. Both algorithms require $O(r^2 N + p(d) r N) $ operations, where $N$ is the initial number of terms in the multivariate mixture, $r$ is the number of selected linearly independent terms, and $p(d)$ is the cost of computing the inner product between two terms of a mixture in $d$ variables. For general Gaussian mixtures $p(d) \sim d^3$ since we need to diagonalize a $d\times d$ matrix, whereas for separated representations $p(d) \sim d$. Due to conditioning issues, the resulting accuracy is limited to about one half of the available significant digits for both algorithms. We also describe an alternative algorithm that is capable of achieving higher accuracy but is only applicable in low dimensions or to multivariate mixtures in separated form. We describe a number of initial applications of these algorithms to solve partial differential and integral equations and to address several problems in data science. For data science applications in high dimensions,we consider the kernel density estimation (KDE) approach for constructing a probability density function (PDF) of a cloud of points, a far-field kernel summation method and the construction of equivalent sources for non-oscillatory kernels (used in both, computational physics and data science) and, finally, show how to use the new algorithm to produce seeds for subdividing a cloud of points into groups.
DIFFRACTION EFFECTS IN MICROLENSING OF Q2237+0305

description: Geometrical optics provides an excellent description for quasar images crossing caustics which are formed by gravitational microlensing of objects like Q2237+0305. Within this approximation the source size can be estimated from the maximum magnification reached at caustic crossings. We evaluate the limitations imposed by diffraction on caustics using the formalism developed by Ulmer & Goodman (1995). Close to a caustic a new characteristic length, smaller that the Fresnel length, enters the problem, limiting the angular resolution to about 0.2 pico arcsecond, or equivalently about 3*10^9 cm at the source. To achieve this resolution the brightness must be monitored at time intervals of a few seconds. If a significant fraction of quasar luminosity comes from sources smaller than those limits then interference effects would make the observed intensity oscillate, in a close analogy with a two slit experiment. The characteristic period of such oscillations is expected to be about one tenth of a minute. If such oscillations are detected then photometry carried out at a single site may permit the determination of the caustic transverse velocity, and therefore may permit a direct conversion of the time units of brightness variations to the linear units at the source.

Extensions of the theory of sampling signals with finite rate of Innovation, performance analysis and an application to single image super-resolution
Creators: name: Wei, Xiaoyao
Publisher: name: Imperial College London
Year: 2016

description: Sampling is the reduction of a continuous-time signal to a discrete sequence. The classical sampling theorem limits the signals that can be perfectly reconstructed to bandlimited signals. In 2002, the theory of finite rate of innovations (FRI) emerged and broadened classical sampling paradigm to classes of signals with finite number of parameters per unit of time, which includes certain classes of non-bandlimited signals. In this thesis we analyse the performance of the FRI reconstruction algorithm and present extensions of the FRI theory. We also extend the FRI theory for the application of image upsampling. First, we explain the breakdown phenomenon in FRI reconstruction by subspace swap and work out at which noise level FRI reconstruction algorithm is guaranteed to achieve the optimal performance given by the Cramer-Rao bound. Our prediction of the breakdown PSNR is directly related to the distance between adjacent Diracs, sampling rate and the order of the sampling kernel and its accuracy is verified by simulations. Next, we propose an algorithm that can estimate the rate of innovation of the input signals and this extends the current FRI framework to a universal one that works with arbitrarily unknown rate of innovation. Moreover, we improve the current identification scheme of “parametrically sparse” systems, i.e. systems that are fully specified by small number of parameters. Inspired by the denoising technique used for FRI signals, we propose the modified Cadzow denoising algorithm which leads to robust system identification. We also show the possibility of perfectly identifying the input signal and the system simultaneously and we also propose reliable algorithm for simultaneous identification of both in the presence of noise. Lastly, by noting that lines of images can be modelled as piecewise smooth signals, we propose a novel image upsampling scheme based on our proposed method for reconstructing piecewise smooth signals which fuses the FRI method with the classical linear reconstruction method. We further improve our upsampled image by learning from the errors of our upsampled results at lower resolution levels. The proposed algorithm outperforms the state-of-the-art algorithms.

description: We investigate magnonic band structure in thin homogeneous permalloy film decorated with periodic array of elliptically shaped permalloy dots and separated by non-magnetic Pt spacer. We demonstrated experimentally formation of the magnonic band structure for Damon-Eshbach wave propagating in permalloy film with the band gap opened at the Brillouin zone border and band splitting at smaller wavenumbers, due to the Bragg interference and interaction of propagating wave of the continuous film with a standing resonant mode of the nano-ellipses, respectively. The shape anisotropy of the permalloy nanodots allows to control the spin wave dynamics through the switch between two states of the magnetization with respect to the underneath film magnetization, thus enabling magnonic band structure reprogrammability. With numerical analysis we show, that predominant role in formation of the magnonic band structure is played by a vertical dynamic coupling between propagating wave in the film and magnetization oscillations in the nanodots.

description: Το βιβλίο θα πραγματεύεται τις βασικές αρχές της Εξελικτικής Βιολογίας στα πλαίσια της διδασκαλίας της σε προπτυχιακό επίπεδο. Δεδομένου ότι τα προγράμματα σπουδών στα Ελληνικά πανεπιστήμια περιλαμβάνουν ελάχιστα μαθήματα συναφή με την Εξέλιξη (τις περισσότερες φορές ένα μόνο μάθημα), το βιβλίο θα προσπαθήσει να καλύψει όσο το δυνατό μεγαλύτερο εύρος του ευρύτατου αντικειμένου της Εξέλιξης.
Αρχικά θα παραθέτει τις ενστάσεις που υπάρχουν για τη θεωρία της Εξέλιξης και τα τεκμήρια που την υποστηρίζουν. Θα αποδεικνύει την Εξέλιξη ως επιστημονική θεωρία και ενοποιητική θεωρία της Βιολογίας. Στη συνέχεια θα επεκτείνεται σε βασικές αρχές Γενετικής Πληθυσμών με την ανάλυση της ισορροπίας Hardy-Weinberg και την περιγραφή του τρόπου με τον οποίο κάθε μια από τις εξελικτικές δυνάμεις (φυσική επιλογή, τυχαία γενετική παρέκκλιση, μετάλλαξη, μετανάστευση) οδηγούν στην εξέλιξη των πληθυσμών. Θα αναλυθούν ειδικές περιπτώσεις φυσικής επιλογής όπως επιλογή ενάντια στο υποτελές ή ενάντια στο κυρίαρχο αλληλόμορφο, υπερκυριαρχία, συχνοεξαρτώμενη επιλογή. Θα περιγραφεί συνοπτικά πώς οι διαφορετικές εξελικτικές δυνάμεις δρουν σε συνδυασμό στους πληθυσμούς π.χ. η επιλογή με την μετάλλαξη. Θα περιγραφεί ο ρόλος της ομομιξίας στην Εξέλιξη και η δυναμική της υποδιαίρεσης πληθυσμών. Θα αναπτυχθεί η ανισορροπία σύνδεσης και ο ρόλος του ανασυνδυασμού στην Εξέλιξη. Ένα χωριστό κεφάλαιο θα αποτελέσει η γενετική των ποσοτικών χαρακτήρων μαζί με την ανθρωπογενή επιλογή.
Σε επόμενη ενότητα θα αναλυθούν οι αρχές της κοινωνιοβιολογίας μέσα από τις αλτρουιστικές και τις συγκρουσιακές συμπεριφορές σε οργανισμικό και σε γενετικό επίπεδο. Ένα κεφάλαιο θα αποτελέσει η φυλοεπιλογή και η εξέλιξη του φύλου καθώς και οι αρχές της ειδογένεσης.
Το βιβλίο θα τελειώνει με σύντομη αναφορά στη Μοριακή Εξέλιξη, δηλαδή τη φυλογένεση και την αλληλεπίδραση της επιλογής με την τυχαία γενετική παρέκκλιση σε μοριακό επίπεδο.

description: We present the first results from a program of near-infrared spectroscopy aimed at studying the familiar rest-frame optical emission lines from the H II regions of Lyman break galaxies at z = 3. By targeting redshifts which bring the lines of interest into gaps between the strong OH sky emission, we have been successful in detecting Balmer and [O III] emission lines in all five galaxies observed so far with CGS4 on UKIRT. For a Salpeter IMF and a H_0 = 70 km/s/Mpc, q_0 = 0.1 cosmology, the Hbeta luminosities uncorrected for dust extinction imply star formation rates of 20 - 270 solar masses per year. On the basis of the present limited sample it appears that an extinction of 1 - 2 magnitudes at 1500 A may be typical of Lyman break galaxies. This value is consistent with recent estimates of dust obscuration in star forming galaxies at z < 1, and does not require a substantial revision of the broad picture of star formation over the Hubble time proposed by Madau et al. (1996). In four out of five cases the velocity dispersion of the emission line gas is sigma = 70 km/s, while in the fifth the line widths are nearly three times larger. Virial masses in the range from 1 x 10^{10} to 5 x 10^{10} solar masses are suggested, but both velocities and masses could be higher because our observations are only sensitive to the brightest cores of these systems where the line widths may not sample the full gravitational potential. The relative redshifts of interstellar absorption, nebular emission, and Lyman alpha emission lines differ by several hundred km/s and suggest that large-scale outflows may be a common characteristic of Lyman break galaxies.

Probing analytical and numerical integrability: The curious case of $(AdS_5\times S^5)_η$

description: Motivated by recent studies related to integrability of string motion in various backgrounds via analytical and numerical procedures, we discuss these procedures for a well known integrable string background $(AdS_5\times S^5)_η$. We start by revisiting conclusions from earlier studies on string motion in $(\mathbb{R}\times S^3)_η$ and $(AdS_3)_η$ and then move on to more complex problems of $(\mathbb{R}\times S^5)_η$ and $(AdS_5)_η$. Discussing both analytically and numerically, we deduce that while $(AdS_5)_η$ strings do not encounter any irregular trajectories, string motion in the deformed five-sphere can indeed, quite surprisingly, run into chaotic trajectories. We discuss the implications of these results both on the procedures used and the background itself.

Figure Rotation and the Mass of the Galactic Bulge

description: The mass of the Galactic bulge, $M_B$, is estimated from the tensor virial theorem. By including the effects of a barred stellar distribution and figure rotation (81 \kms kpc $^{-1}$) and by assuming that the bar is oriented at $θ$ $=$ 20°\ to our line of sight, $M_B$ is found to be as high as 2.8$\times$10$^{10}$ M$_{\odot}$. This estimate is in good agreement with the total mass inferred from the observed optical depth to microlensing for stars toward the inner Galaxy. For larger angles, $θ$ $\sim$ 40°, or smaller pattern speeds (20 \kms kpc $^{-1}$), $M_B$ is found to be $\sim$ 1.7 $-$ 1.9$\times$10$^{10}$ M$_{\odot}$, similar to previous estimates for a barred bulge (2$\times$10$^{10}$ M$_{\odot}$) and axisymmetric bulge (1.8$\times$10$^{10}$ M$_{\odot}$).
