New ultimetallic assemblies as photoluminescent materials
Creators: name: Duerrbeck, Andre
Publisher: name: Imperial College London
Year: 2016

description: During the last few decades significant progress has been made in the area of supramolecular polymers, where monomers are held together by non-covalent interactions. In particular, the formation of macromolecular assemblies by employing a metal-ion induced self-assembly process in solution is of significant interest. These supramolecular metallo-polymers combine common features of traditional covalently-bound polymers with the unique characteristics introduced by metal ions. So far, the research in this area has mainly focused on the metal-induced self-assembly of d-block metals and ditopic tridentate organic ligands. The overall aim of this project was to extend the knowledge in this area to Ln(III)-containing soluble supramolecular metallo-polymers and to study their overall photophysical properties. The introduction chapter gives an overview of the basic principles of lanthanide photophysics as well as brief explanations of the methods used in this thesis. Furthermore, some literature examples of soluble coordination polymers are presented. Chapter two describes the synthesis of new substituted pybox ligands and their complexation to various Ln(III) metal ions. The aim of the chapter was to establish a trend between the ligand triplet state energies and the quantum yield of the Eu(III) and Tb(III) complexes. Chapter three focusses on the preparation of coordination polymers by a self-assembly process in solution between Ln(III) metal ions and ditopic pybox ligands. One ligand was found to result in high Eu(III) emission yields of up to 73% as well as a unique dynamic behaviour in solution. Other ligands prepared showed a quenching mechanism such as energy-back transfer to the ligand triplet state which was further investigated by transient absorption spectroscopy. In chapter four the solution phase self-assembly between Eu(III) and a rigid ditopic tridentate terpyridine ligand which results in the formation of supramolecular metallo-networks in the solid state is described. Depending on the ligand to metal ratio used, the morphology of these materials can be altered from one-dimensional micron-sized fibres to a three-dimensional coordination network. The terpyridine-based ditopic ligand can act as an efficient sensitizer for Eu(III) emission whereby the emission lifetimes and ligand triplet state energies of the metallo-polymers strongly depend on the ligand to metal ratio. The obtained micron-sized fibres can act as an efficient optical wave-guide for Eu(III) emission.

description: We present an analytical formulation of gravitational lensing using familiar triaxial power-law mass distributions, where the 3-dimensional mass density is given by $ρ(X,Y,Z) = ρ_0 [1 + (\frac{X}{a})^2 + (\frac{Y}{b})^2 + (\frac{Z}{c})^2]^{-ν/2}$. The deflection angle and magnification factor are obtained analytically as Fourier series. We give the exact expressions for the deflection angle and magnification factor. The formulae for the deflection angle and magnification factor given in this paper will be useful for numerical studies of observed lens systems. An application of our results to the Einstein Cross can be found in Chae, Turnshek, & Khersonsky (1998). Our series approach can be viewed as a user-friendly and efficient method to calculate lensing properties that is better than the more conventional approaches, e.g., numerical integrations, multipole expansions.

description: The use of wearable devices or "wearables" in the physical activity domain has been increasing in the last years. These devices are used as training tools providing the user with detailed information about individual physiological responses and feedback to the physical training process. Advantages in sensor technology, miniaturization, energy consumption and processing power increased the usability of these wearables. Furthermore, available sensor technologies must be reliable, valid, and usable. Considering the variety of the existing sensors not all of them are suitable to be integrated in wearables. The application and development of wearables has to consider the characteristics of the physical training process to improve the effectiveness and efficiency as training tools. During physical training, it is essential to elicit individual optimal strain to evoke the desired adjustments to training. One important goal is to neither overstrain nor under challenge the user. Many wearables use heart rate as indicator for this individual strain. However, due to a variety of internal and external influencing factors, heart rate kinetics are highly variable making it difficult to control the stress eliciting individually optimal strain. For optimal training control it is essential to model and predict individual responses and adapt the external stress if necessary. Basis for this modeling is the valid and reliable recording of these individual responses. Depending on the heart rate kinetics and the obtained physiological data, different models and techniques are available that can be used for strain or training control. Aim of this review is to give an overview of measurement, prediction, and control of individual heart rate responses. Therefore, available sensor technologies measuring the individual heart rate responses are analyzed and approaches to model and predict these individual responses discussed. Additionally, the feasibility for wearables is analyzed.

description: Design has only recently begun to take an interest in what the non-human means both in the context of design, and what is most popularly called, The Anthropocene. Using anemerging design approach, Transition Design, I use mapping tools and exercises not as a tool for collaboration but as a tool for reflexive inquiry - a tool with which to interrogate my own biases, ways of thinking and knowing. Taking (obvious) hints from Audre Lorde’s The Master s Tools Will Never Dismantle the Master’s house – I dig my heels deeply into they “why” of how things are. Asking who is in charge of knowledge production and how that production of knowledge can be harmfully mediated via biased technologies and ways of seeing. As we see though, through an applied analysis, Transition Design stillstruggles to maintain the radical views it includes in its curriculum. In a world where the prison-industrial complex and environmental injustice intersect deeply, we can onlybegin to see how these two seemingly disparate areas of inquiry can be brought to bear through a new-materialist non-human perspective. I argue that if design and designerswant to engage in meaningful analysis of wicked problems of this epoch, then non-human centered approaches will be our saving grace. The emergence and realization of theimportance of land, situated bodies, and ecosystems asks designers to engage with more materially situated landscapes. Literally. Engaging in and enacting Non-Human discourses in our work is imperative for planetary liberation and justice of all species-beings.
The characteristics, geochemistry and origin of propylitic alteration in the northparkes porphyry Cu-Au system
Creators: name: Pacey, Adam
Publisher: name: Imperial College London
Year: 2016

description: Propylitic alteration is typically the most extensive and peripheral alteration facies developed around porphyry ore deposits. Consequently, with exploration increasingly focused on searching under cover, it may be the only indicator of prospectivity. Understanding its relationship to mineralisation is therefore crucial. However, the genesis of propylitic alteration is poorly understood: deposit models generally assume isochemical processes driven by heated meteoric water. Here, the Northparkes porphyry deposits (NSW) are used to test this paradigm and show how alteration mineral chemistry could assist exploration targeting. Alteration surrounding each Northparkes deposit is zoned from an inner potassic (K-feldspar-biotite) assemblage, through a magnetite-biotite annulus, out into widespread and coeval propylitic (epidote-chlorite) alteration. The quantified net geochemical effects of alteration demonstrate that propylitisation is not isochemical, rather elements are mobilised and dispersed across various facies. Elements lost during potassic alteration are gained in the propylitic zone (e.g. Ca, Fe, Mg, Mn, Co, As) while others either decrease in abundance outwards (e.g. Cu, Au, S, K, Al, Si) or display a halo of elevated values (e.g. Zn, Mn, Pb, C). Investigation of epidote and chlorite chemistry reveals these minerals may host ore-related elements (e.g. Bi, As, Zn, Mn), the concentration of which, along with others (e.g. Ti, Al), is found to vary systematically around mineralised centres. Such trends indicate hypogene dispersion, controlled primarily by temperature and fS2; they have the potential to transform exploration in the propylitic domain. Oxygen isotope geothermometry suggests potassic alteration occurred between ~600-700oC in magmatic centres, persisting to ~450 oC upon transition into propylitic alteration. Across the propylitic facies temperature progressively decreases outwards to <250 oC. The oxygen, hydrogen and strontium isotopic composition of alteration minerals support the involvement of magmatic fluids in all alteration zones. Collectively, the results provide robust evidence that propylitic alteration is a distal equivalent of potassic alteration, driven by spent magmatic-derived ore fluids as they migrate away from thermal centres, cooling and equilibrating with country rocks.

description: A new 3.2--3.5~$μ$m spectrum of the protostar Mon~R2/IRS-3 confirms our previous tentative detection of a new absorption feature near 3.25 $μ$m. The feature in our new spectrum has a central wavelength of 3.256 $μ$m (3071 cm$^{-1}$) and has a full-width at half maximum of 0.079 $μ$m (75 cm$^{-1}$). We explore a possible identification with aromatic hydrocarbons at low temperatures, which absorb at a similar wavelength. If the feature is due to aromatics, the derived column density of C--H bonds is $\sim$1.8 $\times$ $10^{18}$ cm$^{-2}$. If the absorbing aromatic molecules are of roughly the same size as those responsible for aromatic emission features in the interstellar medium, then we estimate that $\sim$9\% of the cosmic abundance of carbon along this line of sight would be in aromatic hydrocarbons, in agreement with abundance estimates from emission features.

The regulation of HTLV-1 integration by a host Co-factor
Creators: name: McCallin, Amy Joanna
Publisher: name: Imperial College London
Year: 2016

description: Retroviruses must integrate a DNA copy of their genome into host cell chromatin to establish infection. The pre-integration complex of the retroviruses, HIV-1 and murine leukemia virus interact with a host co-factor through their integrase enzyme to preferentially integrate into particular sites of host cell chromatin. This results in a unique pattern of integration site distribution in the host genome for each retroviral genus. HTLV-1, a delta-retrovirus, has a well-defined preferential integration pattern that is important for supporting viral gene expression during chronic infection. So far, a deltaretroviral integrase host co-factor has not yet been identified, however, biochemical evidence suggested that the protein phosphatase 2A (PP2A) complex could fulfil this function. Here, I report the results of a Y2H screen which independently confirms that PP2A B’ regulatory subunits interact directly with HTLV-1 IN. Second, I show, using three different experimental approaches, that HTLV-1 integration is redistributed in cells that lack functional PP2A. This is the first evidence that a loss of PP2A activity in live cells leads to an altered integration site preference and strongly suggests that PP2A acts as an HTLV-1 IN co-factor. ShRNA-mediated knockdown of either of the two B’ isoforms most highly expressed in Jurkat T cells, B’ γ and B’ δ, indicates that B’ γ mediates the majority of IN co-factor function, since B’ γ depletion resulted in the most extensive redistribution of integration sites compared to cells treated with control shRNA. However, it is likely that other PP2A holoenzymes can also act as co-factors for HTLV-1 IN. PP2A is ubiquitously and highly expressed, making it an attractive target for co-factor function. Future analysis of PP2A’s co-factor function should aim to use HTLV-1 IN mutants to specifically disrupt the interaction between PP2A and HTLV-1 IN.
Time-reversal invariant topological modes in plasmonic metasurfaces
Creators: name: Proctor, Matthew
Publisher: name: Imperial College London
Year: 2020

description: A prominent goal of nanophotonics is the efficient manipulation of light on the nanoscale. Topological nanophotonics and plasmonics offer a potential path towards realising this through protected modes of light on subwavelength scales at optical frequencies. Inspired by the success of topological modes for electrons, which are robust against a range of defects and disorder, there has been a push towards realising analogues of these modes in photonic systems. Typically these have employed time-reversal breaking components, such as strong magnetic fields or complex engineering of lattice elements, and often operate in narrow frequency regimes, making them difficult to miniaturise to the nanoscale. On the other hand, time-reversal invariant effects which are only reliant on the underlying crystalline symmetry of a lattice are more suitable candidates for hosting subwavelength topological modes. In this thesis, we study the emergence of these modes in the plasmonic metasurface: A two-dimensional lattice of metallic nanoparticles. Individual nanoparticles host localised surface plasmon resonances, which when placed close to other nanoparticles result in collective modes across the system. The strong dipolar coupling between nanoparticles separated by subwavelength distances means many ideas can be brought over from tight- binding models in condensed matter. We begin by examining one-dimensional propagating modes of two different lattice systems. Specifically, we link the crystalline symmetries of the respective bulk phases with topological properties and show how these result in the emergence of edge states. We compare the robustness of these by examining the energy propagation along the interface and in doing so also show how these phases can be used to realise directional propagation of energy. We then study higher-order topology and zero-dimensional localised corner modes in finite lattices. Again we show how these modes arise due to the topology of the bulk, and with this we test the robustness of the modes against disorder. Throughout the thesis, we develop the theoretical understanding of novel concepts in topological nanophotonics, as well as linking the theory to experimental signatures of topology. We do so by presenting results in the context of the experimental state of the art and as well as proposing methods for probing observables in topological plasmonics.
A framework for the optimisation of terminal airspace design in Multi-Airport Systems
Creators: name: Sidiropoulos, Stavros
Publisher: name: Imperial College London
Year: 2016

description: Major cities such as London, New York, and Tokyo are served by several airports, effectively creating a Multi-Airport System (MAS) or Metroplex. Although the operations of individual Metroplex airports are highly interdependent, the current practice is non-integrated, ad-hoc and piecemeal, and over relies on the experience of air traffic controllers to manage the terminal airspace serving the airports. This separate management of MAS airports is complex and does not maximise their operational efficiency. In an attempt to improve MAS operations, the research to date has focused on routing/scheduling algorithms under the assumption that the MAS terminal airspace design is fixed, leading to at best marginal improvements. This thesis proposes a dynamic route concept, that facilitates an integrated approach to the management and operation of MAS terminal airspace. The concept encapsulates a novel procedure for terminal airspace design in MAS, along with a generic methodological framework for its implementation. The dynamic route concept significantly improves the operational efficiency through a paradigm-shift in the design of the operations in MAS terminal airspace. It consists of three components. The first is a new procedure for the robust characterisation of traffic demand based on the spatio-temporal distribution of flights throughout the operational period. The second component is an adaptation of the Analytic Hierarchy Process (AHP) to realise a model for the prioritisation of the dynamic routes, which takes into account quantitative and qualitative attributes important for MAS operations, and enables the decision maker to actively influence the design. The prioritisation model is applied to the dynamic routes derived by the first component. The third component involves priority-based positioning of terminal waypoints, and the design of three-dimensional, conflict-free terminal routes. The latter accounts for the AHP-derived route priorities while satisfying the minimal separation, spatial restriction, and aircraft manoeuvrability constraints. The developed framework is applied to a case study of the New York Metroplex. The effectiveness of the proposed terminal airspace design and its advantages over the current design are demonstrated quantitatively using the AirTOp fast-time simulation model. Overall, significant reductions are achieved for the total distance travelled, total flight duration in the terminal airspace, total fuel burn and total controller workload, ranging from [13%, 21%], [11%, 19%], [10%, 14%] and [25%, 47%], respectively. The framework is also validated qualitatively by subject matter experts involved in the design and operation of the New York Metroplex. The framework elaborated in this thesis tackles the terminal airspace design problem in MAS areas and is recommended for terminal airspace redesign and design for the current and future terminal airspaces, respectively.
Interrogating neuronal connectivity through serial two-photon tomography of the whole mouse brain ex-vivo
Creators: name: Moore, Gerald
Publisher: name: Imperial College London
Year: 2020

description: Ex-vivo, serial two-photon (STP) tomography was used to image the entire mouse brain to interrogate neuronal connectivity across local and distal brain volumes. Large terabyte-sized data sets presented many analytical challenges. To this end, the following pipelines were created and validated; stitching of tile image data, registration of data with common coordinate framework, and a deep learning cell detection algorithm that was comparable to human performance. These pipelines were developed to facilitate two scientific studies. First, the unknown connectivity of local interneurons of the dorsal lateral geniculate nucleus (LGd) of Sox14cre/+ mice were mapped using rabies virus tracing, revealing previously unreported input from the GABAergic reticular nucleus (RT), suggesting a double inhibition mechanism of modulation onto local thalamocortical relay cells. In-vitro patch-clamp recordings confirmed functional connectivity. Thalamic interneurons in the Sox14gfp/+ mouse had high prevalence in first order (FO) sensory nuclei, challenging the notion that interneurons in the mouse thalamus are constrained to visual thalamus only. In-vitro patch-clamp recordings showed functional interneuron-interneuron connectivity as suggested by interneuron morphological analysis. Second, STP tomography and magnetic resonance imaging (MRI) were explored for correlating age-related cognitive changes with anatomical connectivity. Female C57BL/6J mice were subjected to a novel nine-arm radial maze task, and object location and recognition tasks at 4, 8, 12 and 18 months of age. Mice showed remarkable retention of cognitive performance throughout age (n=58). Unique arm choice presented one of many measures that showed performance predictability at 18 months given 4 months performance (R2=0.6166, p<0.0001, n=22). A combination of unique arm sequence length, cumulative arm time and velocity measures showed improved predictability for 18 months performance given 4 months performance (R2=0.6239, p<0.0001, n=22). This level of predictability has been previously seen in Lothian cohort human studies. STP tomography and MRI were used to demonstrate mapping brain connectivity changes with age.

description: The objective of this study was to investigate clinical symptoms, cognitive performance and cortical activity following mild traumatic brain injury (mTBI). We recruited 30 individuals in the sub-acute phase post mTBI and 28 healthy controls with no history of head injury and compared these groups on clinical, cognitive and cortical activity measures. Measures of cortical activity included; resting state electroencephalography (EEG), task related EEG and combined transcranial magnetic stimulation with electroencephalography (TMS-EEG). Primary analyses investigated clinical, cognitive and cortical activity differences between groups. Exploratory analyses investigated the relationships between these measures. At 4 weeks’ post injury, mTBI participants exhibited significantly greater post concussive and clinical symptoms compared to controls; as well as reduced cognitive performance on verbal learning and working memory measures. mTBI participants demonstrated alterations in cortical activity while at rest and in response to stimulation with TMS. The present study comprehensively characterized the multidimensional effect of mTBI in the sub-acute phase post injury, showing a broad range of differences compared to non-mTBI participants. Further research is needed to explore the relationship between these pathophysiologies and clinical/cognitive symptoms in mTBI.

description: We present a scenario (SupraNova) for the formation of GRBs occurring when a supramassive neutron star (SMNS) loses so much angular momentum that centrifugal support against self--gravity becomes impossible, and the star implodes to a black hole. This may be the baryon--cleanest environment proposed so far, because the SN explosion in which the SMNS formed swept the medium surrounding the remnant, and the quickly spinning remnant loses energy through magnetic dipole radiation at a rate exceeding its Eddington luminosity by some four orders of magnitude. The implosion is adiabatic because neutrinos have short mean free paths, and silent, given the prompt collapse of the polar caps. However, a mass ~ 0.1 M_solar in the equatorial belt can easily reach centrifugal equilibrium. The mechanism of energy extraction is via the conversion of the Poynting flux (due to the large--scale magnetic field locked into the minitorus) into a magnetized relativistic wind. Occasionally this model will produce quickly decaying, or non--detectable afterglows.

description: We present spatial, temporal and spectral analyses of ROSAT Position Sensitive Proportional Counter (PSPC) observations of the infrared loud quasar IRAS 13349+2438. IRAS 13349+2438 is the archetypal highly-polarized radio-quiet QSO and has an optical/infrared luminosity of about 2E46 erg/s. We detect variability in the ROSAT count rate by a factor of 4.1 in about one year, and there is also evidence for about 25 per cent variability within one week. We find no evidence for large intrinsic cold absorption of soft X-rays. These two facts have important consequences for the scattering-plus-transmission model of this object which was developed to explain its high wavelength-dependent polarization and other properties. The soft X-ray variability makes electron scattering of most of the soft X-rays difficult without a very peculiar scattering mirror. The lack of significant intrinsic cold X-ray absorption together with the large observed E(B-V) suggests either a very peculiar system geometry or, more probably, absorption by warm ionized gas with internal dust. There is evidence for an ionized oxygen edge in the X-ray spectrum. IRAS 13349+2438 has many properties that are similar to those of the Osterbrockian `narrow-line' Seyfert 1s.

Detection of Far-Infrared Water Vapor, Hydroxyl, and Carbon Monoxide Emissions from the Supernova Remnant 3C 391

description: We report the detection of shock-excited far-infrared emission of H2O, OH, and CO from the supernova remnant 3C 391, using the ISO Long-Wavelength Spectrometer. This is the first detection of thermal H2O and OH emission from a supernova remnant. For two other remnants, W~28 and W~44, CO emission was detected but OH was only detected in absorption. The observed H2O and OH emission lines arise from levels within ~400 K of the ground state, consistent with collisional excitation in warm, dense gas created after the passage of the shock front through the dense clumps in the pre-shock cloud. The post-shock gas we observe has a density ~2x10^5 cm^{-3} and temperature 100-1000 K, and the relative abundances of CO:OH:H2O in the emitting region are 100:1:7 for a temperature of 200 K. The presence of a significant column of warm H2O suggests that the chemistry has been significantly changed by the shock. The existence of significant column densities of both OH and H2O, which is at odds with models for non-dissociative shocks into dense gas, could be due to photodissociation of H2O or a mix of fast and slow shocks through regions with different pre-shock density.

description: We show that a pair of field theory monodromies in which the shift symmetry is broken by small, well motivated deformations, naturally incorporates a mechanism for cancelling off radiative corrections to the cosmological constant. The lighter monodromy sector plays the role of inflation as well as providing a rigid degree of freedom that acts as a dynamical counterterm for the cosmological constant. The heavier monodromy sector includes a rigid dilaton that forces a global constraint on the system and the cancellation of vacuum energy loops occurs at low energies via the sequestering mechanism. This suggests that monodromy constructions in string theory could be adapted to incorporate mechanisms to stabilise the cosmological constant in their low energy descriptions.

description: Recently, we have proposed a quark mass matrix model based on U(3)$\times$U(3)$'$ family symmetry, in which up- and down-quark mass matrices $M_u$ and $M_d$ are described only by complex parameters $a_u $ and $a_d $, respectively. When we use charged lepton masses as additional input values, we can successfully obtain predictions for quark masses and Cabibbo-Kobayashi-Maskawa mixing. Since we have only one complex parameter $a_q$ for each mass matrix $M_q$, we can obtain a parameter-independent mass relation by using three equations for ${\rm Tr}[H_q]$, ${\rm Tr}[H_q H_q]$ and ${\rm det}H_q$, where $H_q \equiv M_q M_q^\dagger$ ($q=u, d$). In this paper, we investigate its parameter-independent feature of the quark mass relation in the model.

description: We have detected the T~Tauri star, DO Tauri, in a 0.6$''$-resolution VLA map of 43.3 GHz ($λ$ = 7 mm) continuum emission. The 43 GHz flux density lies on the same power-law slope defined by 89 to 232 GHz measurements, F$_ν$ $\propto ν^α$ with index $α$ = 2.39$\pm$0.23, confirming that the 43.3 GHz emission is thermal radiation from circumstellar dust. Upper limits to the flux densities at 8.4 and 22.5 GHz constrain the contribution of free-free emission from a compact ionized wind to less than 49\%. The dust emissivity index, $β$, is $0.39\pm$0.23, if the emission is optically thin. Fitting a model of a thin circumstellar disk to the observed spectral energy distribution gives $β= 0.6\pm0.3$, consistent with the power-law derivation. Both values are substantially lower than is generally accepted for the interstellar medium, suggesting grain growth. Given the youth of DO Tau and the early evolutionary state of its circumstellar disk, this result implies that mm-size grains have already formed by the early T-Tauri phase.

description: We study production of dark matter (DM) in models with a non-standard expansion history. We consider both freeze-out and freeze-in mechanisms for producing the observed DM abundance in a model where the DM consists of scalar singlet particles coupled to the Standard Model sector via the Higgs portal. We show that a non-standard expansion phase can lead to a significant change in the DM abundance and therefore to observational ramifications. For example, for DM freeze-in the required portal coupling can be much larger, whereas for DM freeze-out much smaller values become allowed. We evaluate the relevant constraints and discuss prospects for direct detection of such DM.

description: The consumption of bivalve mollusks can represent serious risks to the public health, because they reflect the conditions of the environment directly. This way it is considered of extreme importance the consumption of oyster without contamination. This paper aims of studying the water microbiology quality from the Cooperostra (cooperative of producer) in Cananéia, SP. It was analyzed in the water: total and fecal coliforms. The results found in the water were not satisfactory, suitable with the Brazilian legislation, except for the same month. The intensity of seasonal interferencewas discovered in the microbiological count in the water was verified high positive correlation.

description: Purpose: The purposes of this meta-review are to (a) articulate the importance of transparency and reproducibility in meta-analysis, (b) assess the transparency and reproducibility of meta-analyses published in journals of the American Speech-Language-Hearing Association (ASHA), and (c) discuss the implications of our findings and recommendations for future research.Method: We conducted a meta-review of all meta-analyses published in ASHA journals through December 31, 2020. Our systematic review yielded 47 meta-analyses for inclusion in this review. We coded all eligible reports on the core elements of transparency and reproducibility in meta-analysis.Results: Our findings suggest that though reporting tendencies have improved over time, much work is needed to promote transparency and reproducibility in meta-analytic work. Key areas for future accountability include preregistering study protocol, using Preferred Reporting in Systematic Reviews and Meta-Analysis checklists, providing full data sets, and publishing analytic codes.Conclusions: The state of reporting in meta-analysis is improving over time. We conclude with a discussion of specific areas that need further attention, and recommendations for researchers to consider when conducting future meta-analyses.

The Effects of Starburst Activity on Low Surface Brightness Disk Galaxies

description: Although numerous simulations have been done to understand the effects of intense bursts of star formation on high surface brightness galaxies, few attempts have been made to understand how localized starbursts would affect both the color and surface brightness of low surface brightness (LSB) galaxies. To remedy this, we have run 53 simulations involving bursts of star formation activity on LSB galaxies, varying both the underlying galaxy properties and the parameters describing the starbursts. We discovered that although changing the total color of a galaxy was fairly straightforward, it was virtually impossible to alter a galaxy's central surface brightness and thereby remove it from the LSB galaxy classification without placing a high (and fairly artificial) threshold for the underlying gas density. The primary effect of large amounts of induced star formation was to produce a centralized core (bulge) component which is generally not observed in LSB galaxies. The noisy morphological appearance of LSB galaxies as well as their noisy surface brightness profiles can be reproduced by considering small bursts of star formation that are localized within the disk. The trigger mechanism for such bursts is likely distant/weak tidal encounters. The stability of disk central surface brightness to these periods of star formation argues that the large space density of LSB galaxies at z = 0 should hold to substantially higher redshifts.

Alignment of suprathermally rotating grains

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

description: It is shown, that mechanical alignment can be efficient for suprathermally rotating grains, provided that they drift with supersonic velocities. Such a drift should be widely spread due to both Alfvénic waves and ambipolar diffusion. Moreover, if suprathermal rotation is caused by grain interaction with a radiative flux, it is shown, that mechanical alignment may be present even in the absence of supersonic drift. This means that the range of applicability of mechanical alignment is wider that it is generally accepted and it can rival the paramagnetic one. We also study the latter mechanism and reexamine the interplay between poisoning of active sites and desorption of molecules blocking the access to the active sites of H$_{2}$ formation in order to explain the observed poor alignment of small grains and good alignment of large grains. To have a more comprehensive picture of alignment we briefly discuss the alignment by radiation fluxes and caused by grain magnetic moments.

Occlusion Effects and the Distribution of Interstellar Cloud Sizes and Masses

description: The frequency distributions of sizes of ``clouds" and ``clumps" within clouds are significantly flatter for extinction surveys than for CO spectral line surveys, even for comparable size ranges. A possible explanation is the blocking of extinction clouds by larger foreground clouds (occlusion), which should not affect spectral line surveys much because clouds are resolved in velocity space along a given line of sight. We present a simple derivation of the relation between the true and occluded size distributions, assuming clouds are uniformly distributed in space or the distance to a cloud comples is much greater than the size of the complex. Because the occlusion is dominated by the largest clouds, we find that occlusion does not affect the measured size distribution except for sizes comparable to the largest size, implying that occlusion is not responsible for the discrepancy if the range in sizes of the samples is large. However, we find that the range in sizes for many of the published observed samples is actually quite small, which suggests that occlusion does affect the extinction sample and/or that the discrepancy could arise from the different operational definitions and selection effects involved in the two samples. Size and mass spectra from an IRAS survey (Wood \etal\ 1994) suggest that selection effects play a major role in all the surveys. We conclude that a reliable determination of the ``true" size and mass spectra of clouds will require spectral line surveys with very high signal-to-noise and sufficient resolution and sampling to cover a larger range of linear sizes, as well as careful attention to selection effects.

Heterostrain engineering on twisted graphene bilayer around the first magic angle

description: Very recently, twisted graphene bilayer (TGB) around the first magic angle 1.1° has attracted much attention for the realization of exotic quantum states, such as correlated insulator behavior and unconventional superconductivity. Here we elaborately studied a series of TGBs around the first magic angle engineered by heterostrain, where each layer is strained independently. Our experiment indicated that a moderate heterostrain enables the structural evolution from the small-angle TGB ( ~ 1.5°) to the strained magic-angle TGB (θ ~ 1.1°), exhibiting the characteristic low-energy flat bands. The heterostrain can even drive the system into highly strained tiny-angle TGBs (θ << 1.1°) with large deformed tetragonal superlattices, where a unique network of topological helical edge states emerges. Furthermore, the predicted domain wall modes, which are strongly localized and result in hexagon-triangle-mixed frustrated lattice derived from Kagome lattice, are observed in the strained tiny-angle TGBs.
