description: We present the first nonperturbatively-renormalized determination of the glue momentum fraction $\langle x \rangle_g$ in the nucleon, based on lattice-QCD simulations at physical pion mass using the cluster-decomposition error reduction (CDER) technique. We provide the first practical strategy to renormalize the glue energy-momentum tensor (EMT) nonperturbatively in the RI/MOM scheme, and convert the results to the $\overline{\textrm{MS}}$ scheme with 1-loop matching. The simulation results show that the CDER technique can reduce the statistical uncertainty of its renormalization constant by a factor of ${\cal O}$(300) in calculations using typical state-of-the-art lattice volume, and the nonperturbatively-renormalized $\langle x \rangle_g$ is shown to be independent of the lattice definitions of the glue EMT up to discretization errors. We determine the renormalized $\langle x \rangle_g^{\overline{\textrm{MS}}}(2\textrm{ GeV})$ to be 0.47(4)(11) at physical pion mass, which is consistent with the experimentally-determined value.

Nanomaterials for biosensing and cancer therapy
Creators: name: Jumeaux, Coline Barbara
Publisher: name: Imperial College London
Year: 2016

description: The unique features exhibited by nanomaterials endow them with great potential for applications interfacing with biological systems, and self-assembly enables to gain control over their architecture for fine-tuning of their properties and performances to achieve a highly specific response. High specificity is a key requirement for both biosensing and cancer therapy. This thesis explores the use of self-assembled nanomaterials for the development of new biosensing mechanisms and the design of stimuli-responsive drug delivery platforms for cancer therapy. MicroRNAs (miRNAs) present unique detection challenges, arising from their low abundance in clinical samples, short size, and high sequence homology. Here, DNA-mediated liposome fusion is used for highly specific detection of a clinically-relevant miRNA, initially using a standard laboratory microplate reader. Further, 2-color nanoparticle tracking microscopy is employed to directly follow fusion events occurring in liquid suspension, and a new analytical approach is developed to convert these observations into dose-response curves for increasing the sensitivity of the detection. In parallel, another strategy for increasing the assay sensitivity is explored, involving covalent binding of FRET pair dyes inside lipid bilayers. Further, cancer treatment at the nanoscale allows circumventing the limitations associated with conventional chemotherapy, by providing ways to enhance the treatment’s specificity, increasing the aqueous solubility of anticancer molecules, improving their biodistribution, reversing multidrug resistance, and offering the possibility for personalized therapy. The nanovector employed in this project is the quantum rattle (QR), and is made of a mesoporous silica shell encapsulating gold nanoparticles and gold nanoclusters. In order to address QR towards a systemically administered multifunctional system for cancer therapy, it is engineered into a triggered release drug delivery system. A layer-by-layer type construct is designed using a thermoresponsive polymer, which provides a coating for QR, only allowing drug release after application of a trigger, here laser-induced gold-mediated hyperthermia.
title: A Histological Investigation of the Larval Mandibular Organ in the Mud Crab Rhithropanopeus harrisii (Gould) (Crustacea Decapoda Xanthidae)

description: Mandibular organs of the mud crab, Rhithropanopeus harrisii (Gould) were histologically located and followed throughout the larval cycle to determine their role in metamorphosis. Specimens from each day of the four larval stages and the megalopa stage were embedded in paraffin, sectioned at 8 μm, stained and observed under the microscope for the mandibular organs. The organs were located in the mandibular area of second, third and fourth stage larvae. The organs were probably present in the first stage zoeae and in the megalopa stage, although the

techniques of the study were not sensitive enough to observe them. The activity of the organs varied throughout the larval cycle. They were active during the early stages, much less active in the final larval stage, and inactive in the megalopa stage. These changes in activity suggest that the mandibular organs are secreting a juvenile hormone-like substance that controls metamorphosis.
Exploring networks of the human microbiota in health and disease
Creators: name: Fairclough, Virginia
Publisher: name: Imperial College London
Year: 2016

description: The human microbiota changes throughout our lives and is crucial to our health. However, some perturbations to the microbiota can have life-changing implications for its host. We are still in the early stages of understanding the complexities of these crucial microbial communities; as research into the human microbiota progresses, more methods will be required to explore dependencies between constituents of the microbiota, with the aim of understanding how they interact with each other and their host. In this thesis, I present new methods and tools for creating and analysing networks of the human microbiota. I present a new method for analysing and comparing microbial dependencies in disease cases when compared to controls. This method is applied to real data taken from patients, and I draw inferences from the results, which agree well with the existing scientific literature. This analysis is followed by the generation of weighted metagenome-scale metabolic networks. This novel approach presents the metabolic capabilities of the microbiota in a new manner, whilst providing a basis for future comparisons between the metabolic profiles found within the microbiota of cases and controls. As well as presenting the metabolic capabilities of the community as a whole, it would be beneficial to be able to model a particular metabolic symbiosis. However, the current bottleneck in this area of research is due to slow curation of genome-scale metabolic models. Therefore, this thesis ends with the presentation of a new tool to aid the curation of genome-scale metabolic models and its application, with the hope that it may be used to improve existing models prior to the creation of models of metabolic symbiosis.

description: It is imperative for all stakeholders that digital forensics investigations produce reliable results to ensure the field delivers a positive contribution to the pursuit of justice across the globe. Some aspects of theseinvestigations are inevitably contingent on trust, however this is not always explicitly considered or critically evaluated. Erroneously treating features of the investigation as trusted can be enormously damaging to the overall reliability of an investigation's findings as well as the confidence that external stakeholders can have in it. As an example, digital crime scenes can be manipulated by tampering with the digital artefacts left on devices, yet recent studies have shown that efforts to detect occurrences of this are rare and argue that this leaves digital forensics investigations vulnerable to accusations of inaccuracy. In this paper a new approach to digital forensics is considered based on the concept of Zero Trust, an increasingly popular design in network security. Zero Trust describes the practitioner mindset and principles upon which the reliance on trust in network components is eliminated in favour of dynamic verification of network interactions. An initial Definition of Zero Trust Digital Forensics will be proposed and then a specific example considered showing how this strategy can be applied to digital forensic investigations to mitigate against the specific risk of evidence tampering. A definition of Zero Trust Digital Forensics is proposed, specifically that it is ‘a strategy adopted by investigators whereby each aspect of an investigation is assumed to be unreliable until verified’. A new principle will be introduced, namely the ‘multifaceted verification of digital artefacts’ that can be used by practitioners who wish to adopt a Zero Trust Digital Forensics strategy during their investigations. A qualitative review of existing artefact verification techniques is also conducted in order to briefly evaluate the viability of this approach based on current research efforts.

Publisher: name: The APO
Year: 2022

description: The COVID-19 pandemic made a significant impact on all people worldwide. Many workers were unemployed due to the closure of businesses and shutdowns of companies everywhere. Employability of the Hotel and Restaurant Management from 2015 – 2021 was the primary concern of this study to set innovations to strengthen not only the academic performances of the hospitality management students but also upskilling present and future HM students facing and serving the industry with the culture of excellence. The study reveals that most HRM graduate respondents were from the age group of 21-23 males who are single and have a college degree.  Most are employed permanently and work as waiters/waitresses/food servers. This only shows that the employability of HRM graduates from batch 2015 to 2021 is very satisfying, as they are employed in a very related job. However, some of the graduate respondents have jobs unrelated to their specialization. This will be considered as a percentage of mismatch. It is hard to cope with or get a better job during this pandemic. However, the HRM graduates made it through even the highest salary they received, ranging from the minimum wage. Though they received a minimum amount with maximum service provided, graduate respondents managed to deal with daily life challenges.

description: Increasing knowledge of the relationship between cancer and dysregulated polyamine catabolism suggests interfering with aberrant polyamine metabolism for anticancer therapy that will have considerable clinical promise. SMO (spermine oxidase) plays an essential role in regulating the polyamines homeostasis. Therefore, development of SMO inhibitors has increasingly attracted much attention. Previously, we successfully purified and characterised SMO. Here, we presented an in silico drug discovery pipeline by combining pharmacophore modelling and molecular docking for the virtual screening of SMO inhibitors. In vitro evaluation showed that N-(3-{[3-(dimethylamino)propyl]amino}propyl)-8-quinolinecarboxamide (SI-4650) inhibited SMO enzyme activity, increased substrate spermine content and reduced product spermidine content, indicating that SI-4650 can interfere with polyamine metabolism. Furthermore, SI-4650 treatment suppressed cell proliferation and migration. Mechanistically, SI-4650 caused cell cycle arrest, induced cell apoptosis, and promoted autophagy. These results demonstrated the properties of interfering with polyamine metabolism of SI-4650 as a SMO inhibitor and the potential for cancer treatment.

description: We study the bulk-boundary correspondence for topological crystalline phases, where the crystalline symmetry is an order-two (anti)symmetry, unitary or antiunitary. We obtain a formulation of the bulk-boundary correspondence in terms of a subgroup sequence of the bulk classifying groups, which uniquely determines the topological classification of the boundary states. This formulation naturally includes higher-order topological phases as well as topologically nontrivial bulk systems without topologically protected boundary states. The complete bulk and boundary classification of higher-order topological phases with an additional order-two symmetry or antisymmetry is contained in this work.

description: Compact groups of galaxies appear to be extremely dense, making them likely sites of intense galaxy interaction, while their small populations make them relatively simple to analyze. In order to search for optical interaction tracers such as diffuse light and galaxy tidal features in Hickson compact groups (HCGs), we carried out deep photometry in three filters on a sample of HCGs with $ROSAT$ observations. Using a modeling procedure to subtract the light of bright early-type galaxies, we found shell systems and extended envelopes around many, but not all, of those galaxies. Only one group in our sample, HCG 94, has diffuse light in the group potential (with a luminosity of 7 L$^*$); the other groups do not contain more than 1/3 L$^*$ in diffuse light. With the exception of HCG 94 (which is the most X-ray--luminous HCG), we found no correlation between the presence of shells or other tidal features and the X-ray luminosity of a group. Better predictors of detectable group X-ray emission are a low spiral fraction and belonging to a larger galaxy condensation---neither of which are correlated with optical disturbances in the group galaxies. Two elliptical galaxies that are extremely optically luminous but X-ray--faint are found to have shells and very complex color structures. This is likely due to recent infall of gas-rich material into the galaxies, which would produce both the disruption of stellar orbits and a significant amount of star formation.

description: We develop a low-frequency perturbation theory in the extended Floquet Hilbert space of a periodically driven quantum systems, which puts the high- and low-frequency approximations to the Floquet theory on the same footing. It captures adiabatic perturbation theories recently discussed in the literature as well as diabatic deviation due to Floquet resonances. For illustration, we apply our Floquet perturbation theory to a driven two-level system as in the Schwinger-Rabi and the Landau-Zener-Stückelberg-Majorana models. We reproduce some known expressions for transition probabilities in a simple and systematic way and clarify and extend their regime of applicability. We then apply the theory to a periodically-driven system of fermions on the lattice and obtain the spectral properties and the low-frequency dynamics of the system.

description: We construct a proposal for effective bosonic field theory at order $ α'^3 $ in twelve dimensions, whose compactification on a circle and on a torus respectively yields eleven-dimensional and type IIB supergravity theories at eight-derivative level. The couplings $ ({\partial {G_5}})^2 R^2 $, $ ({\partial {F_4}})^2 R^2 $, $ ({\partial {F_4}})^4 $, $ ({\partial {G_5}})^4 $ and $ ({\partial {G_5}})^2({\partial {F_4}})^2 $ in twelve-dimensional supergravity are determined with this requirement that an ansatz of these couplings should admits a consistent truncation to the eleven-dimensional and type IIB supergravity theories. The self-duality condition of the five-form field strength in twelve dimensions is also understood by considering the RR five-form field strength of type IIB theory at linear order.

description: The context within which rural people in Latin America farm and put together their livelihoods is changing rapidly: farmers are faced with increasingly competitive markets, input price rises and in some cases environmental degradation. It is also the case that these livelihoods have become ever more complex, and many rural families are not able to support themselves on agricultural activities alone. This implies that concentrating resources on agricultural technology development may not be the most effective response to the needs of many rural people whose livelihoods are more affected by other parts of the food system (such as agroindustry), or by other economic activities (such as migration). Insofar as training is part of a rural support programme, this interpretation also implies that assisting rural people in the development of new skills to help them deal with problems they currently cannot deal with may be more useful than agricultural technology training. The experiences of Indian organisations in Ecuador and Bolivia also suggest that the most successful rural support programmes are those that acknowledge the need to enter non-agricultural training and to address off-farm income generation. Overall, the most successful organizations have promoted a bottomup controlled process of agricultural modernization, rather than a traditional knowledge based strategy. Interestingly, the strongest organizations, and those that have had particular impact on rural poverty, are those that have first concentrated on the context rather than the content of rural livelihoods (by addressing issues of land rights, agroindustry, marketing, rural banking etc). They have then developed agricultural research and extension strategies on the basis of these other activities, not vice versa. There are general lessons to be learnt regarding the organization of research and extension and the role that farmer organization can play in this. The paper concludes with a discussion of these lessons.
The scatter in the near-infrared colour-magnitude relation in spiral galaxies

description: We have determined a dust-free colour-magnitude (CM) relation for spiral galaxies, by using I-K colours in edge-on galaxies above the plane. We find that the scatter in this relation is small and approximately as large as can be explained by observational uncertainties. The slope of the near-IR CM relation is steeper for spirals than for elliptical galaxies. We suggest two possible explanations. First, the difference could be caused by vertical colour gradients in spiral galaxies. In that case these gradients should be similar for all galaxies, on average 0.15 dex in [Fe/H] per scale height, and increase for later galaxy types. The most likely explanation, however, is that spirals and ellipticals have intrinsically different CM relations. This means that the stars in spirals are younger than those in ellipticals. The age, however, or the fraction of young stars in spiral galaxies, would be determined solely by the galaxy's luminosity, and not by its environment.

description: We model a massless viscous disk using Smoothed Particle Hydrodynamics (SPH) and note that it evolves according to the Lynden-Bell \& Pringle theory (1974) until a non-axisymmetric instability develops at the inner edge of the disk. This instability may have the same origin as the instability of initially axisymmetric viscous disks discussed by Lyubarskij et al. (1994). To clarify the evolution we evolved single and double rings of particles. It is actually inconsistent with the SPH scheme to set up a single ring as an initial condition because SPH assumes a smoothed initial state. As would be expected from an SPH simulation, the ring rapidly breaks up into a band. We analyse the stability of the ring and show that the predictions are confirmed by the simulation.

description: A relation between the precanonical quantization of pure Yang-Mills fields and the functional Schrödinger representation in the temporal gauge is discussed. It is shown that the latter can be obtained from the former when the ultraviolet parameter $\varkappa$ introduced in precanonical quantization goes to infinity. In this limiting case, the Schrödinger wave functional can be expressed as the trace of the Volterra product integral of Clifford-algebra-valued precanonical wave functions restricted to a certain field configuration, and the canonical functional derivative Schrödinger equation together with the quantum Gauß constraint are derived from the Dirac-like precanonical Schrödinger equation.

description: In holographic duality, the entanglement entropy of a boundary region is proposed to be dual to the area of an extremal codimension-2 surface that is homologous to the boundary region, known as the Hubeny-Rangamani-Takayanagi (HRT) surface. In this paper, we study when the HRT surfaces of two boundary subregions R, A are in the same Cauchy slice. This condition is necessary for the subregion-subregion mapping to be local for both subregions and for states to have a tensor network description. To quantify this, we study the area of a surface that is homologous to A and is extremal except at possible intersections with the HRT surface of R (minimizing over all such possible surfaces), which we call the constrained area. We give a boundary proposal for an upper bound of this quantity, a bound which is saturated when the constrained surface intersects the HRT surface of R at a constant angle. This boundary quantity is the minimum entropy of region A in a modular evolved state -- a state that has been evolved unitarily with the modular Hamiltonian of R. We can prove this formula in two boundary dimensions or when the modular Hamiltonian is local. This modular minimal entropy is a boundary quantity that probes bulk causality and, from this quantity, we can extract whether two HRT surfaces are in the future or past of each other. These entropies satisfy some inequalities reminiscent of strong subadditivity and can be used to remove certain corner divergences.

Changes in Cord Blood Dendritic Cells as Biomarkers of Fetal Exposure to Stressor Stimuli
Creators: name: Oliver, Reeba
Publisher: name: Imperial College London
Year: 2012

description: DCs are central to fetal defences and it was postulated that phenotypic changes on CBDCs in response to infectious/stressor stimuli could identify compromised fetuses. Investigations were performed on whole blood using monoclonal antibody labelling and flow cytometry. Functional studies included endocytosis of Dextran particles and MLR. Both plasmacytoid (HLA-DR⁺CD11c⁻) and myeloid (HLA-DR⁺CD11c⁺) DCs were identified in CB. Additionally CB contained a DC subset with a HLA-DR⁺CD11c⁻CD45^intermediate(inm) phenotype. This population expressed lower levels of CD45 and HLA-DR and did not express plasmacytoid (CD123, BDCA2, and CD45RA) or myeloid (CD33 and CD13) markers. All subsets exhibited endocytosis and unlabelled CBDCs exhibited lymphocytic stimulatory capacity. Both myeloid and plasmacytoid CBDC subsets showed no change with gestation. The CD11c⁻ CD45^inm subset decreased with increasing gestation representing 31.33% of total DCs in preterm, 21.26% in term CB and 1.54% in adult PB. CD11c⁻CD45inm DC numbers expressing CD40, CD86 and production of IL-12 increased significantly with stressors. The myeloid and the plasmacytoid subsets showed no upregulation of CD40 and CD86 with stressors. The myeloid subset decreased while the plasmacytoid subset increased IL-12 production with stressors. Neutrophilic activation markers of CD11b and CD16 showed significant correlation with the stressed CB samples which exhibited proinflammatory DC responses, thus validating the clinical classification. These data indicate that CB contains plasmacytoid and myeloid DC populations as seen in adult PB. Additionally this study has identified a hitherto unreported CBDC subset with an immature phenotype, exhibiting endocytosis and phenotypically distinct from plasmacytoid DCs. Of the three subsets, only the CD11c⁻CD45^inm subset showed a costimulatory response to stressors suggesting this subset to be the most kinetic; changing with advancing gestation as well as exposure to stressors. Thus investigating phenotypic changes on CBDC subsets, especially on the CD11c⁻CD45^inm subset, could serve to identify fetuses exposed to stressor stimuli and at risk of adverse sequelae.
Plastic buckling of columns and plates
Creators: name: Jowhari Moghadam, Shirin
Publisher: name: Imperial College London
Year: 2015

description: The theory of buckling strength of compression members in the plastic range has been extensively studied, and numerical methods already exist which deal with such behaviour. However, there is a significant research interest in developing analytical models for the plastic buckling, largely driven by the need for simplified mechanics based design tools, but also by the desire for enhanced understanding of this complex phenomenon. A thorough investigation into the inelastic buckling of columns and plates reveals the existence of two well-known inconsistencies recognised as the “Column Paradox” and the “Plate Plastic Buckling Paradox”. In the current research, addressing the conceptual issues related to the plastic buckling of columns and plates, including the two associated paradoxes, has been achieved by means of development and application of analytical models that are verified against nonlinear finite element analysis. These models are based on sound principles of structural mechanics and are intended to illustrate the mechanics of the plastic buckling response of stocky columns/plates by means of a simplified analytical approach, from the point of buckling initiation and considering the post-buckling response. In these models, the Rotational Spring Analogy is used for formulating the geometric stiffness matrix, whereas the material stiffness matrix is obtained with due consideration for the spread of material plasticity. It is shown that the buckling of stocky perfect columns starts at the Engesser load while the von Karman upper limit is typically not realised due to tensile yielding at the outer fibre of the column cross-section. Furthermore, it is established that beyond a threshold level of imperfection, as evaluated directly from the developed model, the plastic post-buckling response of columns is barely affected by a further increase in the out-of-straightness. Besides identifying previous misconceptions in the research literature, the proposed analytical models for the plastic buckling of plates have proven to offer valuable insight into factors that influence the plastic buckling of stocky plates, and hence succeeded in resolving the long-standing paradox. It is the major contention of this thesis, verified through extensive studies, that the “Plate Plastic Buckling Paradox” is resolved with the correct application of plasticity theory, considering not only the influence of initial imperfections but also the interaction between flexural and planar actions.

A direct proof of these universal properties would be impractical due to the complicated coherence conditions arising from polynomial composition; however, in this paper we avoid most of these coherence conditions using the properties of generic bicategories. In addition, we give a new proof of the universal properties of the bicategory of spans, and also establish the universal properties of the bicategory of spans with invertible 2-cells; showing how these properties may be used to describe the universal properties of polynomials.

This study aimed to investigate (1) Changes in eating behaviour and meal patterns after VSG, (2) Changes in sweet taste detection thresholds after VSG, (3) Changes in appetitive behaviour as a marker of changes in reward after VSG, and (4) Changes in consummatory behaviour as a marker of changes in reward after VSG in adolescents' subjects. The project recruited 50 adolescents after VSG and 35 as controls. The ages were 15 ± 0.27 and 14 ± 0.28 for the subjects after VSG and controls respectively. 42 % of the subjects were females and 58 % males, with the mean BMI of (51.1 ± 1.0) for VSG and (31.9 ± 1.1) for control subject. The parameters recorded for each aim included; Aim 1: Meal duration, meal size, pre-meal hunger and post-meal satiation that were assessed before and after VSG. Attitudes to foods, 24h recall method and FFQ were measured. Aim 2: The intensity of sweet taste stimuli assessed before and after VSG, using the constant stimuli methods. Aim 3: The appetitive reward of fat and sweet taste stimuli was assessed before and after VSG, using the Progressive Ratio Task. Aim 4: The consummatory reward of fat and sweet taste stimuli was assessed before and after VSG, using taste reactivity by recording and analysing facial expressions to determine the ingestive behaviour in response to stimulants. The results demonstrated; Aim 1: Changes in food preferences towards healthier choices, eating behaviour and meal pattern after VSG (all p <0.05). Aim 2: No changes in sucrose detection threshold after VSG (p= 0.6). Aim 3: Appetitive reward value as measured by the breakpoint of the tastant decreased after VSG (p=0.02). Aim 4: Consummatory reward value of the tastant as measured by behaviours associated with positive ingestive behaviours decreased after VSG as well (p= 0.03). In conclusion obese adolescents after VSG have a shift in food preferences to healthier food choices, as well as eating behaviour and meal patterns. VSG changed the Hedonic value of high fat and sugary food as suggested by changes in Appetitive and Consummatory behaviour in response. However VSG had no effect on the sensory domain as regards sweet sensitivity. Taken together VSG may improve the quality of food selected after surgery by reducing the reward value of high fat and sugary foods.

description: We describe a $^{3}$He-$^{129}$Xe comagnetometer operating in stemless anodically bonded cells with a 6 mm$^3$ volume and a $^{129}$Xe spin coherence time of 300 sec. We use a $^{87}$Rb pulse-train magnetometer with co-linear pump and probe beams to study the nuclear spin frequency shifts caused by spin polarization of $^{3}$He. By systematically varying the cell geometry in a batch cell fabrication process we can separately measure the cell shape dependent and independent frequency shifts. We find that a certain aspect ratio of the cylindrical cell can cancel the effects of $^3$He magnetization that limit the stability of vapor-cell comagnetometers. Using this control we also observe for the first time a scalar $^{3}$He-$^{129}$Xe collisional frequency shift characterized by an enhancement factor $κ_{\text{HeXe}} = -0.011\pm0.001$.

Experimentally measured oscillator strengths and associated radiative lifetimes of neutral vanadium using Fourier Transform Spectroscopy and Laser-Induced Fluorescence

description: Modern astrophysical analysis requires increasing higher resolution laboratory spectra over a broader spectral range. The advances in ground- and space-based telescopes are highlighting the deficiencies in the current laboratory spectral database. This thesis reports on the research carried out on the high resolution laboratory measurements of the spectrum of neutral vanadium and the associated lifetime measurements to calculate transition probabilities. New measurements of radiative atomic lifetimes were made for 25 levels between 24648 cm−1 and 37518 cm−1 at the Lund Laser Center, Sweden, using the time resolved Laser-induced Fluorescence method. High Resolution Fourier Transform (FT) Spectroscopy is used to observe the hollow cathode lamp spectrum of neutral vanadium in the range 2000 cm−1 - 35000 cm−1. This range was covered using two high resolution FT Spectrometers in Imperial College London and Lund University (Sweden) with a resolving power of approximately 2 million and 1 million respec- tively. This resolving power enables line profiles to be fully resolved to the Doppler width. The high resolution spectra were used to measure the branching fractions of levels of interest which were then used in combination with the lifetime measurements to calculate the oscillator strengths. Across the UV, visible and IR spectral regions, radiative lifetimes and oscillator strengths for 208 lines between 3040 ̊A and 20000 ̊A from 39 upper energy levels are reported. 13 of these oscillator strengths have not been reported previously. Additionally new measurements were made of hyperfine structure splitting factors for 3 odd levels of V I lying between 24700 cm−1 and 28400 cm−1.

Notes: Until recently, C. ownbeyi was known only from its type locality / the locus classicus in Bolivia (Wheeler 2002a). The additional records from northern Argentina (Jiménez-Mejías et al. 2016a), Colombia (Jiménez-Mejías et al. 2018), and now Peru confirm that this species is much more widespread through the Andes than previously believed and much under-collected.

Causality and the Power Spectrum

description: We find constraints on the generation of super-causal-horizon energy perturbations from a smooth initial state, under a simple physical scheme. We quantify these constraints by placing the upper limit $λ_c = 3.0 d_H$ on the wavelength at which the power spectrum turns over to $k^4$ behavior. This means that sub-horizon processes can generate significant power on scales further outside the horizon than one might naively expect. The existence of this limit may have important implications for the interpretation of the small scale power spectrum of the Cosmic Microwave Background.
