description: This paper presents an integral concurrent learning (ICL)-based observer for a monocular camera to accurately estimate the Euclidean distance to features on a stationary object, under the restriction that state information is unavailable. Using distance estimates, an infinite horizon optimal regulation problem is solved, which aims to regulate the camera to a goal location while maximizing feature observability. Lyapunov-based stability analysis is used to guarantee exponential convergence of depth estimates and input-to-state stability of the goal location relative to the camera. The effectiveness of the proposed approach is verified in simulation, and a table illustrating improved observability is provided.

description: We report the results of an optical spectroscopic follow-up of four double quasar candidates in the Sloan Digital Sky Survey (SDSS) database. SDSS J1617+3827 is most likely a lensed quasar at z = 2.079, consisting of two images with r ~ 19-21 and separated by ~ 2 arcsec. We identify an extended source northeast of the brightest image as an early-type lensing galaxy at z = 0.602, and detect a candidate for the main deflector in the vicinity of the faintest image. SDSS J2153+2732 consists of two distinct but physically associated quasars at z ~ 2.24 (r ~ 19-20, separation of 3.6 arcsec). Although this system might be a binary quasar, there is evidence of a collision or merger within a galaxy cluster at an early stage. The other two candidates are projected pairs of active galactic nuclei: SDSS J1642+3200 (separation of ~ 3 arcsec) comprises a distant quasar (r ~ 18) at z = 2.263 and the active nucleus (r > 20) of a galaxy at z ~ 0.3, while SDSS J0240-0208 (r ~ 18-19, separation of ~ 1 arcsec) is a pair of quasars at z = 1.687 and z = 1.059. In each of these two systems, the background quasar only suffers a weak gravitational lensing effect by the host galaxy of the foreground active nucleus, so the host galaxy mass is constrained to be less than (2.9-3) x 10^{11} solar masses inside 10 kpc.

description: The precision of intensity measurements of the extragalactic X-ray Background (XRB) on an angular scale of about a degree is dominated by spatial fluctuations caused by source confusion noise. X-ray source counts at the flux level responsible for these fluctuations will soon be accurately measured by new missions and it will then be possible to detect the weaker fluctuations caused by the clustering of the fainter, more distant sources which produce the bulk of the XRB. We show here that measurements of these excess fluctuations at the level of 0.2 per cent are within reach, improving by an order of magnitude on present upper limits. Together with the redshift evolution of the X-ray volume emissivity in the Universe, this can be used to measure the power spectrum of the density fluctuations at comoving wavevectors 0.01-0.1 h/Mpc at z=1-2 with a sensitivity better than the predictions from large-scale structure models. A relatively simple X-ray experiment, carried out by a large-area proportional counter with a 0.5-2 deg^2 collimated field-of-view scanning the whole sky a few times, would be able to determine the power spectrum of the density fluctuations near its expected peak in wavevector with an accuracy better than 10 per cent.

It suggests the existence of a chiral condensate which we confirm with a direct stochastic estimate. We show that the part of the spectrum responsible for the chiral condensate can be understood as arising from a dilute gas of instantons and anti-instantons.

description: Split learning is a simple solution for Vertical Federated Learning (VFL), which has drawn substantial attention in both research and application due to its simplicity and efficiency. However, communication efficiency is still a crucial issue for split learning. In this paper, we investigate multiple communication reduction methods for split learning, including cut layer size reduction, top-k sparsification, quantization, and L1 regularization. Through analysis of the cut layer size reduction and top-k sparsification, we further propose randomized top-k sparsification, to make the model generalize and converge better. This is done by selecting top-k elements with a large probability while also having a small probability to select non-top-k elements. Empirical results show that compared with other communication-reduction methods, our proposed randomized top-k sparsification achieves a better model performance under the same compression level.

description: The objective of this research is to produce a critical scientific analysis of some aspects related to urban resilience to offer planners and decision-makers a deft intervention tool to mitigate high temperatures in urban areas. Densification, morphology, and materials are used to suggest strategies aimed at improving the quality of life in cities. This point of view analyses climate change and its connection to humans, urban density and its energy value, the evolution of materials, and the management of environmental comfort, considering the horizontal/vertical relationship as one of the morphological parameters capable of determining the connections between density, the form of the spaces, and the urban heat island.

description: Entangled light sources for illuminating objects offer advantages over conventional illumination methods by enhancing the detection sensitivity of reflecting objects. The core of the quantum advantage lies in effectively exploiting quantum correlations to isolate noise and detect objects with low reflectivity. This work experimentally demonstrates the benefits of using polarization-entangled photon pairs for quantum illumination and shows that the quantum correlation measure, using CHSH value and normalized CHSH value, is robust against losses, noise, and depolarization. We report the detection of objects with reflectivity ($η$) as low as 0.05 and an object submerged in noise with a signal-to-noise ratio of 0.003 using quantum correlation and residual quantum correlation measures, surpassing previous results. Additionally, we demonstrate that the normalized CHSH value aids in estimating the reflectivity of the detected object. Furthermore, we analyze the robustness of the correlation measure under photon attenuation in atmospheric conditions to show the practical feasibility of real-time applications.

description: A quarkonium-gluonium mixing scheme previously developed to describe the characteristic of the pseudoscalar mesons is applied to axial and tensor mesons. The parameters of the model are determined by fitting the eigenvalues of a mass matrix. The corresponding eigenvectors give the proportion of light quarks, strange quarks and glueball in each meson. However the predictions of the model for branching ratios and electromagnetic decays are incompatible with the experimental results. These results suggest the absence of gluonic components in the states of axial and tensor isosinglet mesons analyzed here.

description: We study the dynamical behavior of a non-Hermitian moire superlattice system, which consists of two-coupled SSH chains with staggered imaginary on-site potentials. There are two main spatial regions, in which systems are in unbroken symmetric phases with fully real spectrum, appearing periodically along the ladder. We show that the two quantum phases are dimerized and tetramerized, which determine the distinct dynamical behaviors. Dirac probability can oscillate periodically, increase quadratically and increase exponentially, which correspond to the unbroken phase, exceptional point and the broken phase of the tetramerized region. In comparison, the Dirac probability can exhibit high-frequency oscillation in the dimerized region. These phenomena demonstrate the dynamical signature and provide insightful information of the moire pattern in the non-Hermitian regime.

description: We present evidences for the connection between the potential of different fields and complexity growth rates both in conformal and confining cases. By studying different models, we also establish a strong connection between phase transitions and the discontinuities in the complexity growth rates. In the first example, for the dyonic black holes which are dual to van der Waals fluids, we find a similar first order phase transition in the behavior of complexity growth rate. We then compare the Schwinger effect and also the behavior of complexity in the AdS and AdS soliton backgrounds and comment on the connection between them. Finally, in a general Gubser model of QCD, we present the connections between the potentials, entropies, speed of sounds and complexity growth rates during crossover, first and second order phase transitions and also the behavior of quasinormal modes.

Privacy Paradox: Online Privacy Behaviors and Attitudes in Qatar

description: Privacy has been debated for centuries with scholars struggling to find an all-encompassing definition that collects the distinct features of this concept (Solove, 2008). With the spread of social media networks, the debate to define. It has been consistently found that online users worry about their privacy, while not taking any measures to change their online behaviors to better protect their privacy, in a phenom known as the "privacy paradox" (Barnes, 2006). In this thesis I look at the privacy paradox in regards to online users in Qatar and their understanding of privacy on social media networks by using a quantitative and qualitative survey distributed via WhatsApp to residents of Qatar. I argue that the privacy paradox exists within Qatar and online users do not find recent scandals involving the different social media networks a threat to their online privacy due to many reasons including their lack of understanding of the impact, the geographical nature of these breaches and their natural inclination to censor their own content by avoiding any posts that they deem private.

description: Dark matter is hypothetical matter believed to address the missing mass problem in galaxies. However, alternative theories, such as Modified Newtonian Dynamics (MOND), have been notably successful in explaining the missing mass problem in various astrophysical systems. The vertical distribution function of stars in the solar neighbourhood serves as a proxy to constrain galactic dynamics in accordance to its contents. We employ both the vertical positional and velocity distribution of stars in cylindrical coordinates with a radius of 150 pc and a half-height of 200 pc from the galactic plane. Our tracers consist of main-sequence A, F, and early-G stars from the GAIA, RAVE, APOGEE, GALAH, and LAMOST catalogues. We attempt to solve the missing mass in the solar neighbourhood, interpreting it as either dark matter or MOND. Subsequently, we compare both hypotheses newtonian gravity with dark matter and MOND, using the Bayes factor (BF) to determine which one is more favoured by the data. We found that the inferred dark matter in the solar neighbourhood is in range of $\sim (0.01$-$0.07)$ M$_{\odot}$ pc$^{-3}$. We also determine that the MOND hypothesis's acceleration parameter $a_0$ is $(1.26 \pm 0.13) \times 10^{-10}$ m s$^{-2}$ for simple interpolating function. The average of bayes factor for all tracers between the two hypotheses is $\log \textrm{BF}\sim 0.1$, meaning no strong evidence in favour of either the dark matter or MOND hypotheses.

description: Introduction: Inhaled antibiotics may improve symptom scores but it is not known which specific symptoms improve with therapy. Item-level analysis of questionnaire data may allow us to identify which specific symptoms respond best to treatment.

Methods: Post-hoc analysis of the AIR-BX1 and 2 trials of inhaled aztreonam versus placebo in bronchiectasis. Individual items from the quality of life bronchiectasis respiratory symptom scale (QOL-B) were extracted, as representing severity of 9 distinct symptoms. Generalised linear models were used to evaluate changes in symptoms with treatment versus placebo from baseline to end of first on treatment cycle and mixed models used to evaluate changes across the full 16 week trial.

Results: Aztreonam improved cough (difference 0.22; 95%CI 0.08-0.37, p=0.002), sputum production (0.30; 95%CI 0.15-0.44, p<0.0001) and sputum colour (0.29; 95%CI 0.15-0.43 p<0.0001) versus placebo equating to a 20% improvement in cough and 25% improvement in sputum production and colour respectively. Similar results were observed for cough, sputum production and sputum purulence across the trial duration (all p<0.05). Patients with higher sputum production and sputum colour scores had a greater response on the overall QOL-B (difference 4.82; 95%CI 1.12-8.53, p=0.011) for sputum production and 5.02; 95%CI 1.19-8.86, p=0.01 for sputum colour. In contrast, treating patients who had lower levels of bronchitic symptoms resulted in shorter time to next exacerbations (HR 1.83; 95%CI 1.02-3.28, p=0.042).

Conclusion: Baseline bronchitic symptoms predict response to inhaled aztreonam in bronchiectasis. More sensitive tools to measure bronchitic symptoms may be useful to enrich for inhaled antibiotic responders and to evaluate patient response to treatment.
Semi-analytical Proof of Abelian Dominance on Confinement in the Maximally Abelian Gauge

description: We study abelian dominance for confinement in terms of the local gluon properties in the maximally abelian (MA) gauge in a semi-analytical manner with the help of the lattice QCD. The global Weyl symmetry persistently remains as the relic of SU($N_c$) in the MA gauge, and provides the ambiguity on the electric and magnetic charges. We derive the criterion on the SU($N_c$)-gauge invariance in terms of the residual symmetry in the abelian gauge. In the lattice QCD, we find microscopic abelian dominance on the link variable for the whole region of $β$ in the MA gauge. The off-diagonal angle variable, which is not constrained by the MA-gauge fixing condition, tends to be random besides the residual gauge degrees of freedom. Within the random-variable approximation for the off-diagonal angle variable, we prove that off-diagonal gluon contribution to the Wilson loop obeys the perimeter law in the MA gauge, and show exact abelian dominance for the string tension, although small deviation is brought by the finite size effect of the Wilson loop in the actual lattice QCD simulation.

The systemic approach in sustainable environmental planning: references to the ecology of living systems

description: The article investigates the possibility of adopting indicators and analytical methods characteristic of the living systems ecology to understand different territorial metabolism phenomena. In addition to explore and orient deep sustainability processes in the transformation of the urban fabric, supporting a circular and self-sustaining economic model. The interpretation of the horizontal / vertical theme is twofold: on one hand, the material substrate of the design process is observed by a high level, such as enabling to grasp systemic connections necessary to eco-environmental scale; on the other hand, the construction of interactive networks promotes the emergence of new configurations in decision-making processes. The in-depth analysis of the analytical tools applied to natural metabolic processes combines the choice of horizontal or vertical physical configuration to achieve the following objective: maximizing the work obtainable (ie. the service provided to live, feed and move) with the same solar energy used. This constitutes the main law that regulates the evolution of natural terrestrial ecosystems (Odum, 1996) and represents the fundamental criterion for defining profound sustainability in the planning / design production processes of the built environment (Daly, 2008).

Angular Momentum and Galaxy Formation Revisited: Scaling Relations for Disks and Bulges

Year: 2018
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We show that the stellar specific angular momentum j_*, mass M_*, and bulge fraction beta_* of normal galaxies of all morphological types are consistent with a simple model based on a linear superposition of independent disks and bulges. In this model, disks and bulges follow scaling relations of the form j_*d ~ M_*d^alpha and j_*b ~ M_*b^alpha with alpha = 0.67 +/- 0.07 but offset from each other by a factor of 8 +/- 2 over the mass range 8.9 <= log M_*/M_Sun <= 11.8. Separate fits for disks and bulges alone give alpha = 0.58 +/- 0.10 and alpha = 0.83 +/- 0.16, respectively. This model correctly predicts that galaxies follow a curved 2D surface in the 3D space of log j_*, log M_*, and beta_*. We find no statistically significant indication that galaxies with classical and pseudo bulges follow different relations in this space, although some differences are permitted within the observed scatter and the inherent uncertainties in decomposing galaxies into disks and bulges. As a byproduct of this analysis, we show that the j_*--M_* scaling relations for disk-dominated galaxies from several previous studies are in excellent agreement with each other. In addition, we resolve some conflicting claims about the beta_*-dependence of the j_*--M_* scaling relations. The results presented here reinforce and extend our earlier suggestion that the distribution of galaxies with different beta_* in the j_*--M_* diagram constitutes an objective, physically motivated alternative to subjective classification schemes such as the Hubble sequence.

description: We present the results of an HST and ground-based imaging study of a complete 3C sample of z ~ 1 sources, including 5 quasars and 5 radio galaxies. We have resolved continuum structure around all of our quasars in the WFPC2 images and in four of the five ground-based K' images. All of the quasars have some optical continuum structure that is aligned with the radio axis. In 3 of these cases, some of this optical structure is most likely due to optical synchrotron radiation, including optical counterparts to two radio jets and one radio lobe. Two quasars have aligned continuum and emission-line structures that are probably not due to beamed optical synchrotron emission. In another quasar, we see a red aligned object that lies 3 arcsec beyond the radio lobe, and may be an unassociated foreground galaxy, but has a remarkable morphological resemblance to the radio lobe itself. The radio galaxies and the quasars in this small sample have similar incidence of alignment, and the optical and K' flux densities are consistent within the high dispersion. The average quasar host galaxy luminosity is equivalent to, or a little fainter than, L*. All components around the quasars have optical-infrared colors that are redder than or similar to the colors of their respective nuclei; this is generally more consistent with a stellar rather than scattered origin for the emission. This study provides qualitative support for the unification of FRII quasars and galaxies.

description: The paper proposes a reflection and a point of view on the design of the contemporary hospital and the architectures for health according to “vertical” or “horizontal” typologies. The aim is to identify in various configurations, the relationships between the quality of the spaces and specific requirements in relation to the most recent developments in medicine both from the organizational and functional points of view and the social component. The method consists in defining a framework of demanding and performance comparison of different hypotheses, supported by indirect and direct analysis of the outcomes, through an analysis matrix related to case studies, considered as best practices among the architectures for health.

description: Recent advances in the study of cobaltites have unveiled their potential as a promising platform for realizing Kitaev physics in honeycomb systems and the Ising model in weakly coupled chain materials. In this manuscript, we explore the magnetic properties of pyroxene SrCoGe$_2$O$_6$ using a combination of neutron scattering, {\it ab initio} methods, and linear spin-wave theory. Through careful examination of inelastic neutron scattering powder spectra, we propose a modified Kitaev model to accurately describe the twisted chains of edge-sharing octahedra surrounding Co$^{2+}$ ions. The extended Kitaev-Heisenberg model, including a significant anisotropic bond-dependent exchange term with $K/|J|=0.96$, is identified as the key descriptor of the magnetic interactions in SrCoGe$_2$O$_6$. Furthermore, our heat capacity measurements reveal an effect of an external magnetic field (approximately 13~T) which shifts the system from a fragile antiferromagnetic ordering with $T_{\mathrm{N}}=9$~K to a field-induced state. We argue that pyroxenes, particularly those modified by substituting Ge with Si and its less extended $p$ orbitals, emerge as a novel platform for the Kitaev model. This opens up possibilities for advancing our understanding of Kitaev physics.

description: Today, there is a plethora of software security tools employing visualizations that enable the creation of useful and effective interactive security analyst dashboards. Such dashboards can assist the analyst to understand the data at hand and, consequently, to conceive more targeted preemption and mitigation security strategies. Despite the recent advances, model-based security analysis is lacking tools that employ effective dashboards---to manage potential attack vectors, system components, and requirements. This problem is further exacerbated because model-based security analysis produces significantly larger result spaces than security analysis applied to realized systems---where platform specific information, software versions, and system element dependencies are known. Therefore, there is a need to manage the analysis complexity in model-based security through better visualization techniques. Towards that goal, we propose an interactive security analysis dashboard that provides different views largely centered around the system, its requirements, and its associated attack vector space. This tool makes it possible to start analysis earlier in the system lifecycle. We apply this tool in a significant area of engineering design---the design of cyber-physical systems---where security violations can lead to safety hazards.

description: Gravity compresses the matter in the cores of neutron stars to densities which are significantly higher than the density of ordinary atomic nuclei, thus providing a high-pressure environment in which numerous particle processes - from the generation of new baryonic particles to quark deconfinement to the formation of Boson condensates and H-matter - may compete with each other. There are theoretical suggestions of even more `exotic' processes inside pulsars, such as the formation of absolutely stable strange quark matter, a configuration of matter even more stable than the most stable atomic nucleus, iron. In the latter event, neutron stars would be largely composed of pure quark matter, eventually enveloped in nuclear crust matter. No matter which physical processes are actually realized inside neutron stars, each one leads to fingerprints, some more pronounced than others though, in the observable stellar quantities. This feature combined with the tremendous recent progress in observational radio and X-ray astronomy, renders neutron stars to nearly ideal probes for a wide range of dense matter studies, complementing the quest of the behavior of superdense matter in terrestrial collider experiments.

title: Progress towards the synthesis of perophoramidine : formation of the contiguous quaternary centres

description: Perophoramidine 1 is a halogenated natural product which contains two contiguous quaternary centres within its structure. In this thesis, approaches towards the synthesis of perophoramidine are described. In particular, the synthesis of the tetracyclic core structure and the formation of the quaternary centres have been examined. In Chapter 1, the natural product perophoramidine 1 is introduced and its isolation, structure and biological activity is discussed. The structurally related communesin family of natural products are also introduced before the literature published on both the biosynthesis and laboratory synthesis of perophoramidine 1, is reviewed. Finally the Westwood group’s approach towards the synthesis of perophoramidine 1 is introduced with a summary of non-halogenated model system investigations previously carried out within the group being provided. Chapter 2 describes studies towards the synthesis of an appropriately halogenated indolo[2,3-b]quinoline core structure of perophoramidine 1. This then allowed methodology previously developed within the group on model system substrates to be applied to the formation of the first of the two quaternary centres required for the synthesis of perophoramidine 1. Chapter 3 describes the attempted formation of the second quaternary centre using an ester alkylation approach. After initial studies failed to generate the desired quaternary centre, non-halogenated model system studies were carried out in an attempt to develop an alternative approach. In Chapter 4, model system studies were continued with cyclic ether compounds investigated as potential intermediates towards the synthesis of perophoramidine 1. The results obtained in this chapter provided a novel route to the formation of the second quaternary centre and led to a redesigned approach towards perophoramidine 1 being developed. In Chapter 5, this redesigned approach was applied to the halogenated intermediates synthesised in Chapter 1. This led to the formation of the first halogenated intermediate synthesised within the group which contained the two contiguous quaternary centres required for the synthesis of perophoramidine 1.

description: A novel and facile route to bimetallic molybdenum phosphides was described. Both NiMoP and CoMoP phosphides were successfully prepared by a hexamethylenetetramine (HMT) route. Mixed-salt precursors containing HMT, M-HMT (M = Ni, Co or Mo) complexes, MMo-HMT (M = Ni or Co) complexes and P-containing species can be directly converted to bimetallic molybdenum phosphides under a flow of Ar at 800 °C. It was proposed that the bimetallic phosphides were formed via two possible reaction pathways: (i) MMo-HMT complexes/P→MMoP (M = Ni or Co) and (ii) M-HMT (M = Ni, Co or Mo) complexes/P→M2P/MoP→MMoP (M = Ni or Co). Additionally, it was found that the dispersions and surface areas of NiMoP and CoMoP prepared by HMT route were higher than those of corresponding bimetallic phosphides prepared by traditional H2 reduction method.

description: Structure and stability of diastereoisomers of cucurbit[n]urils (CB[n = 5–10]), the inverted CB[n]s, were investigated by density functional theory (DFT) computations. All the inverted CB[n]s were less stable than their normal CB[n]s and the mono-inverted ones with one inverted glycoluril unit in their structures were more stable than their doubly-inverted isomers. Relative change in dipole moments and molecular electrostatic potentials (MEP) were discussed with the deformation in geometric structure and charge distribution of the normal and inverted CB[n]s.

description: Circulant preconditioners for functions of matrices have been recently of interest. In particular, several authors proposed the use of the optimal circulant preconditioners as well as the superoptimal circulant preconditioners in this context and numerically illustrated that such preconditioners are effective for certain functions of Toeplitz matrices. Motivated by their results, we propose in this work the absolute value superoptimal circulant preconditioners and provide several theorems that analytically show the effectiveness of such circulant preconditioners for systems defined by functions of Toeplitz matrices. Namely, we show that the eigenvalues of the preconditioned matrices are clustered around $\pm 1$ and rapid convergence of Krylov subspace methods can therefore be expected. Moreover, we show that our results can be extended to functions of block Toeplitz matrices with Toeplitz blocks provided that the optimal block circulant matrices with circulant blocks are used as preconditioners. Numerical examples are given to support our theoretical results.

description: The excitation of the proton into undetected multiparticle states (double diffraction dissociation) is an important background to single diffractive deep-inelastic processes $ep \rightarrow e'p'ρ^{0}, ~e'p'J/Ψ, ~e'p'X$ at HERA. We present estimates of the admixture of the double diffraction dissociation events in all diffractive events. We find that in the $J/Ψ$ photoproduction, electroproduction of the $ρ^0$ at large $Q^2$ and diffraction dissociation of real and virtual photons into high mass states $X$ the contamination of the double diffraction dissociation can be as large as $\sim 30\%$, thus affecting substantially the experimental tests of the pomeron exchange in deep inelastic scattering at HERA. We discuss a possibility of tagging the double diffraction dissociation by neutrons observed in the forward neutron calorimeter. We present evaluations of the spectra of neutrons and efficiency of neutron tagging based on the experimental data for diffractive processes in the proton-proton collisions.
