description: West African savannas are severely threatened with intensified land use and increasing degradation. Bees are important for terrestrial biodiversity as they provide native plant species with pollination services. However, little information is available regarding their mutualistic interactions with woody plant species. In the first network study from sub-Saharan West Africa, we investigated the effects of land-use intensity and climatic seasonality on plant–bee communities and their interaction networks. In total, we recorded 5686 interactions between 53 flowering woody plant species and 100 bee species. Bee-species richness and the number of interactions were higher in the low compared to medium and high land-use intensity sites. Bee- and plant-species richness and the number of interactions were higher in the dry compared to the rainy season. Plant–bee visitation networks were not strongly affected by land-use intensity; however, climatic seasonality had a strong effect on network architecture. Null-model corrected connectance and nestedness were higher in the dry compared to the rainy season. In addition, network specialization and null-model corrected modularity were lower in the dry compared to the rainy season. Our results suggest that in our study region, seasonal effects on mutualistic network architecture are more pronounced compared to land-use change effects. Nonetheless, the decrease in bee-species richness and the number of plant–bee interactions with an increase in land-use intensity highlights the importance of savanna conservation for maintaining bee diversity and the concomitant provision of ecosystem services.

description: The urinary albumin-to-creatinine ratio (UACR) is a widely used indicator of albuminuria and has predictive value for adverse cardiovascular events.To evaluate the correlation between the UACR and the risk of developing major adverse cardiovascular events (MACEs) and total mortality in patients with type 2 diabetes mellitus (T2DM).This post-hoc analysis included 10,171 participants from the Action to Control Cardiovascular Risk in Diabetes (ACCORD) study and the ACCORD Follow-up study with baseline UACR data. The natural logarithm (ln) of each UACR measurement was calculated. Univariate and multivariate Cox proportional hazard regression analyses were conducted to examine the association between the UACR and the risk of MACEs and total mortality. The additional predictive value of UACR was further evaluated. Similar methods were used to analyze the correlation between the UACR and MACEs and total mortality within the normal range.During a median follow-up period of 8.83 years, 1808 (17.78%) participants experienced MACEs, and there were 1934 (19.01%) total mortality. After adjusting for traditional cardiovascular risk factors, the multivariate analysis revealed a significant association between the UACR and the risk of MACEs and total mortality. The inclusion of UACR in the conventional risk model enhanced the predictive efficacy for MACEs and total mortality.An elevated UACR is associated with a higher risk of MACEs and total mortality in patients with T2DM, even when it falls below the normal range. The UACR improves MACE and total mortality risk prediction in patients with T2DM.

description: Mammalian genomes are a battleground for genetic conflict between repetitive elements and KRAB-zinc finger proteins (KZFPs). We asked whether KZFPs can regulate cell fate by using ZFP819, which targets a satellite DNA array, ZP3AR. ZP3AR coats megabase regions of chromosome 7 encompassing genes encoding ZSCAN4, a master transcription factor of totipotency. Depleting ZFP819 in mouse embryonic stem cells (mESCs) causes them to transition to a 2-cell (2C)-like state, whereby the ZP3AR array switches from a poised to an active enhancer state. This is accompanied by a global erosion of heterochromatin roadblocks, which we link to decreased SETDB1 stability. These events result in transcription of active LINE-1 elements and impaired differentiation. In summary, ZFP819 and TRIM28 partner up to close chromatin across Zscan4, to promote exit from totipotency. We propose that satellite DNAs may control developmental fate transitions by barcoding and switching off master transcription factor genes.

description: Parameters of 24-h rhythm in intraocular pressure (IOP) were assessed in patients with stable or advanced primary open-angle glaucoma (S-POAG/A-POAG) and referenced to the phase of “marker” circadian temperature rhythm of each patient. Body temperature and IOP were measured over a 72-h span in 115 participants (65 S-POAG and 50 A-POAG). Retinal Ganglion Cell (RGC) damage was assessed by high-definition optical coherence tomography. The 24-h IOP rhythm in A-POAG patients peaked during the night, opposite to the daytime phase position in S-POAG patients (p < 0.0001). The 24-h IOP phase correlated with RGC loss (p < 0.0001). The internal phase shift between IOP and body temperature gradually increased with POAG progression (p < 0.001). Angiotensin converting enzyme Alu-repeat deletion/insertion (ACE I/D) emerged as a candidate gene polymorphism, which may play a role in the alteration of the circadian IOP variability in advanced glaucoma. To conclude, a reliable estimation of the 24-h rhythm in IOP requires the degree of RGC damage to be assessed. In advanced POAG, the 24-h phase of IOP tended to occur during the night and correlated with RGC loss, being progressively delayed relative to the phase of temperature.

description: We study the distribution of cold dark matter (CDM) in cosmological simulations from the FIRE (Feedback In Realistic Environments) project, for $M_{\ast}\sim10^{4-11}\,M_{\odot}$ galaxies in $M_{\rm h}\sim10^{9-12}\,M_{\odot}$ halos. FIRE incorporates explicit stellar feedback in the multi-phase ISM, with energetics from stellar population models. We find that stellar feedback, without "fine-tuned" parameters, greatly alleviates small-scale problems in CDM. Feedback causes bursts of star formation and outflows, altering the DM distribution. As a result, the inner slope of the DM halo profile ($α$) shows a strong mass dependence: profiles are shallow at $M_{\rm h}\sim10^{10}-10^{11}\,M_{\odot}$ and steepen at higher/lower masses. The resulting core sizes and slopes are consistent with observations. This is broadly consistent with previous work using simpler feedback schemes, but we find steeper mass dependence of $α$, and relatively late growth of cores. Because the star formation efficiency $M_{\ast}/M_{\rm h}$ is strongly halo mass dependent, a rapid change in $α$ occurs around $M_{\rm h}\sim 10^{10}\,M_{\odot}$ ($M_{\ast}\sim10^{6}-10^{7}\,M_{\odot}$), as sufficient feedback energy becomes available to perturb the DM. Large cores are not established during the period of rapid growth of halos because of ongoing DM mass accumulation. Instead, cores require several bursts of star formation after the rapid buildup has completed. Stellar feedback dramatically reduces circular velocities in the inner kpc of massive dwarfs; this could be sufficient to explain the "Too Big To Fail" problem without invoking non-standard DM. Finally, feedback and baryonic contraction in Milky Way-mass halos produce DM profiles slightly shallower than the Navarro-Frenk-White profile, consistent with the normalization of the observed Tully-Fisher relation.

description: The work presented in this thesis is concerned with the database security aspects. In particular, we address the problem of querying encrypted data in graph databases. The thesis considers the most popular databases security methods from the literature: (i) multi-layered encryption and (ii) encryption adjustment. The encryption is one of the eﬀective ways to protect sensitive data in a database from various attacks. Querying encrypted data includes two challenges. Either the data should be decrypted before the querying, leaving it vulnerable to server-side attacks, or one has to apply computationally expensive methods for querying encrypted data.

description: GJ3470b is a hot Neptune exoplanet orbiting an M dwarf and the first sub-Jovian planet to exhibit Rayleigh scattering. We present transit timing variation (TTV) and transmission spectroscopy analyses of multi-wavelength optical photometry from 2.4-m and 0.5-m telescopes at the Thai National Observatory, and the 0.6-m PROMPT-8 telescope in Chile. Our TTV analysis allows us to place an upper mass limit for a second planet in the system. The presence of a hot Jupiter with a period of less than 10 days or a planet with an orbital period between 2.5 and 4.0 days are excluded. Combined optical and near-infrared transmission spectroscopy favour an H/He dominated haze (mean molecular weight 1.08$\pm$0.20) with high particle abundance at high altitude. We also argue that previous near-infrared data favour the presence of methane in the atmosphere of GJ3470b.

description: This research project aims to look at the anatomical characteristics and the chemical signatures of plant-based raw materials of basketry in the South of France-Mediterranean area. I propose to interview basket makers and study museum collections (such as the Mucem) to gather data on the properties of local plants. The goal is to select plants of well-identified use and provenance (plant status such as native, introduced, invasive) to create a database. This database aims to characterise plant material with its specific anatomical properties and chemical content. This work will enable us to (1) discover how materials are linked from a multidisciplinary point of view and (2) to improve the characterisation of plants in an archaeological context or in museum collections. (3) On the basis of the results obtained from the database, I will create prototypes of biodegradable plant-based objects to offer a local alternative to plastic objects.

description: While the 12C(a,g)16O reaction plays a central role in nuclear astrophysics, the cross section at energies relevant to hydrostatic helium burning is too small to be directly measured in the laboratory. The beta-delayed alpha spectrum of 16N can be used to constrain the extrapolation of the E1 component of the S-factor; however, with this approach the resulting S-factor becomes strongly correlated with the assumed beta-alpha branching ratio. We have remeasured the beta-alpha branching ratio by implanting 16N ions in a segmented Si detector and counting the number of beta-alpha decays relative to the number of implantations. Our result, 1.49(5)e-5, represents a 24% increase compared to the accepted value and implies an increase of 14% in the extrapolated S-factor.

description: We invoke a Gaussian mixture model (GMM) to jointly analyse two traditional emission-line classification schemes of galaxy ionization sources: the Baldwin–Phillips–Terlevich (BPT) and WH α versus [N ii]/H α (WHAN) diagrams, using spectroscopic data from the Sloan Digital Sky Survey Data Release 7 and SEAGal/STARLIGHT data sets. We apply a GMM to empirically define classes of galaxies in a three-dimensional space spanned by the log [O iii]/H β, log [N ii]/H α and log EW(H α) optical parameters. The best-fitting GMM based on several statistical criteria suggests a solution around four Gaussian components (GCs), which are capable to explain up to 97 per cent of the data variance. Using elements of information theory, we compare each GC to their respective astronomical counterpart. GC1 and GC4 are associated with star-forming galaxies, suggesting the need to define a new starburst subgroup. GC2 is associated with BPT's active galactic nuclei (AGN) class and WHAN's weak AGN class. GC3 is associated with BPT's composite class and WHAN's strong AGN class. Conversely, there is no statistical evidence – based on four GCs – for the existence of a Seyfert/low-ionization nuclear emission-line region (LINER) dichotomy in our sample. Notwithstanding, the inclusion of an additional GC5 unravels it. The GC5 appears associated with the LINER and passive galaxies on the BPT and WHAN diagrams, respectively. This indicates that if the Seyfert/LINER dichotomy is there, it does not account significantly to the global data variance and may be overlooked by standard metrics of goodness of fit. Subtleties aside, we demonstrate the potential of our methodology to recover/unravel different objects inside the wilderness of astronomical data sets, without lacking the ability to convey physically interpretable results. The probabilistic classifications from the GMM analysis are publicly available within the COINtoolbox at https://cointoolbox.github.io/GMM_Catalogue/.
Particle acceleration in superluminal strong waves

description: We calculate the electron acceleration in random superluminal strong waves (SLSWs) and radiation from them by using numerical methods in the context of the termination shock of the pulsar wind nebulae. We pursue the electrons by solving the equation of motion in the analytically expressed electromagnetic turbulences. These consist of primary SLSW and isotropically distributed secondary electromagnetic waves. Under the dominance of the secondary waves, all electrons gain nearly equal energy. On the other hand, when the primary wave is dominant, selective acceleration occurs. The phase of the primary wave felt by the electrons moving nearly along the wavevector changes very slowly compared to the oscillation of the wave, which is called "phase locked", and such electrons are continuously accelerated. This acceleration by SLSWs may play a crucial role in the pre-acceleration for the shock acceleration. In general, the radiation from the phase-locked population is different from the synchro-Compton radiation. However, when the amplitude of the secondary waves is not extremely weaker than that of the primary wave, the typical frequency can be estimated from the synchro-Compton theory by using the secondary waves. The primary wave does not contribute to the radiation, because the SLSW accelerates electrons almost linearly. This radiation can be observed as a radio knot at the upstream of the termination shock of the pulsar wind nebulae without counter parts in higher frequency range.

description: We analyse the clustering of cosmic large scale structure using a consistent modified gravity perturbation theory, accounting for anisotropic effects along and transverse to the line of sight. The growth factor has a particular scale dependence in f(R) gravity and we fit for the shape parameter f_{R0} simultaneously with the distance and the large scale (general relativity) limit of the growth function. Using more than 690,000 galaxies in the Baryon Oscillation Spectroscopy Survey Data Release 11, we find no evidence for extra scale dependence, with the 95\% confidence upper limit |f_{R0}| <8 \times 10^{-4}. Future clustering data, such as from the Dark Energy Spectroscopic Instrument, can use this consistent methodology to impose tighter constraints.

title: Electron diagnostics of magnetron discharges
Creators: name: Ryan, Peter
Publisher: name: University of Liverpool Repository
Year: 2020

description: The magnetron is a weakly magnetised plasma source used for physical vapour deposition to produce high-quality thin films and coatings for technological applications. In this research, electron plasma property measurements were performed in conventional DC magnetron discharges and in high power impulse magnetron sputtering (HiPIMS) discharges. The two main topics of this thesis are: (i) a comparison of electron plasma property measurements made by Langmuir probe and incoherent laser Thomson scattering, and (ii) an investigation of electron dynamics in HiPIMS discharges using a combination of incoherent laser Thomson scattering and optical emission spectroscopy. Electrons are responsible for driving many important processes in low temperature discharge plasmas, such as, plasma heating, ionisation and plasma chemistry. The Langmuir probe is commonly employed to measure electron plasma properties, but its data can be difficult to interpret, especially from magnetised plasma. The aim of the first part of the research was to assess the accuracy of electron plasma property measurements made by Langmuir probes in weakly magnetised plasma, by comparing the results from the probe measurements with reliable results obtained via laser Thomson scattering. Standard unmagnetised theories were used to interpret the probe data. The range of magnetic field strength, electron temperature and electron density in the study were 110^{19} m^{-3}), metal-rich plasma propagating along the axial direction from the magnetic trap region to a typical substrate position. The main outcomes from this research were experimental confirmation of the expected features of HiPIMS discharges using the reliable laser Thomson scattering technique, and validation of trends identified in previous Langmuir probe studies at a typical substrate position. Therefore, the results provide a solid foundation for the understanding of electron dynamics in HiPIMS.

description: The internal and external flow field of a fluidic oscillator with two feedback channels are examined experimentally within the incompressible flow regime. A scaled-up device with a square outlet nozzle is supplied with pressurized air and emits a spatially oscillating jet into quiescent environment. Time-resolved information are obtained by phase-averaging pressure and PIV data based on an internal reference signal. The temporal resolution is better than a phase angle of 3°. A detailed analysis of the internal dynamics reveals that the oscillation mechanism is based on fluid feeding into a separation bubble between the jet and mixing chamber wall which pushes the jet to the opposite side. The total volume of fluid transported through one feedback channel during one oscillation cycle matches the total growth of the separation bubble from its initial size to its maximum extent. Although the oscillation frequency increases linearly with supply rate, sudden changes in the internal dynamics are observed. These changes are caused by a growth in reversed flow through the feedback channels. The time-resolved properties of the emitted jet such as instantaneous jet width and exit velocity are found to oscillate substantially during one oscillation cycle. Furthermore, the results infer that the jet’s oscillation pattern is approximately sinusoidal with comparable residence and switching times.

description: We present HST spectroscopy for 45 cataclysmic variables (CVs), observed with HST/COS and HST/STIS. For 36 CVs, the white dwarf is recognisable through its broad Ly α absorption profile and we measure the white dwarf effective temperatures (Teff) by fitting the HST data assuming log g = 8.35, which corresponds to the average mass for CV white dwarfs (≃0.8 M⊙). Our results nearly double the number of CV white dwarfs with an accurate temperature measurement. We find that CVs above the period gap have, on average, higher temperatures (〈Teff〉 ≃ 23 000 K) and exhibit much more scatter compared to those below the gap (〈Teff〉 ≃ 15 000 K). While this behaviour broadly agrees with theoretical predictions, some discrepancies are present: (i) all our new measurements above the gap are characterized by lower temperatures (Teff ≃ 16 000–26 000 K) than predicted by the present-day CV population models (Teff ≃ 38 000–43 000 K); (ii) our results below the gap are not clustered in the predicted narrow track and exhibit in particular a relatively large spread near the period minimum, which may point to some shortcomings in the CV evolutionary models. Finally, in the standard model of CV evolution, reaching the minimum period, CVs are expected to evolve back towards longer periods with mean accretion rates $$\dot{M}\lesssim 2 \times 10^{-11}\,\mathrm{M}_{\odot }\,\mathrm{yr}^{-1}$$, corresponding to Teff ≲ 11 500 K. We do not unambiguously identify any such system in our survey, suggesting that this major component of the predicted CV population still remains elusive to observations.

description: The detection of an unidentified emission line in X-ray spectra of cosmic objects would be a 'smoking gun' signature for particle physics beyond the Standard Model. More than a decade of its extensive searches results in several narrow faint emission lines reported at 3.5, 8.7, 9.4 and 10.1 keV. The most promising of them is the emission line at ~3.5 keV reported in spectra of several nearby galaxies and galaxy clusters. Here I summarize its up-to-date status, overview its possible interpretations, including an intriguing connection with radiatively decaying dark matter, and outline future directions for its studies.

Making equality law work for Deaf people
Creators: name: Wilks, Robert B.
Publisher: name: University of Leicester

Subjects: Uncategorized

description: Equality law is not working for Deaf1 people. The majority of deaf children attend mainstream schools without resource provision and are often denied the opportunity to engage with their deaf peers. Deaf people are likely to be in underemployment or unemployed and discrimination in the workplace is commonplace. There is evidence of injustice within the criminal justice system for deaf people, Deaf people are not able to serve their civic duty as jurors, and their access to legal advice services is dire. Deaf prisoners suffer a ‘double sentence’ when in prison, and deaf people generally do not have access to healthcare services. Thus, this thesis seeks to explore why equality law is not working for Deaf people, and what can be done to ensure that it does. In order to answer this research question, after a consideration of what evidence exists to suggest that Deaf people continue to experience inequalities, an attempt is made to ascertain why the framing of Deaf people as disabled is problematic, giving rise to what is termed the ‘Deaf Legal Dilemma,’ whereby Deaf people are faced with a stark choice: accept the disability label, or have no access to any rights at all. There is then an attempt to determine which concepts of equality are relevant to Deaf people, utilising a specific methodology that allows the author to categorise these concepts into either formal, substantive or transformative equality thus establishing a standard of measurement by which it is possible to determine how effective particular concepts of equality are in eradicating inequality. A doctrinal analysis of equality law in the UK is then undertaken, incorporating the Universal Declaration of Human Rights, the European Convention on Human Rights, the Equality Act 2010 and the United Nations Convention on the Rights of Persons with Disabilities. These are critiqued in order to establish how they apply or may apply to Deaf people, and how effective they are in addressing their inequalities. The findings of this analysis are that the instruments examined are not effective, and sign language recognition is proposed as a solution. The conclusion reached is that sign language recognition proffers a transformative approach to the Deaf Legal Dilemma and should – at least in the long term - give Deaf people ‘equal and inalienable rights’ on par with hearing people, in full cognisance of their status as Sign Language Peoples.
title: Dihydroorotate dehydrogenase regulates ER membrane reorganisation and cell death in cancer
Creators: name: Yedida, Govinda
Publisher: name: University of Liverpool Repository

description: The endoplasmic reticulum (ER) exists as an elaborated network of flat sheets and cylindrical tubules. ER network interacts with several other organelles, including mitochondria to play a vital role in membrane dynamics and other functions. However, the impact of ER-mitochondrial interactions on apoptosis is poorly understood. Cancer cells acquire resistance to anti-cancer agents through different mechanisms, including failure to undergo apoptosis. Therefore, better understanding of ER-mitochondrial communications and their impact on apoptosis could unravel mechanisms of drug resistance. We have previously observed a reversible reorganisation of ER membranes in cells exposed to several pharmaceutical agents. Hence, we conducted this study using ER membrane reorganisation as a tool to explore ER-mitochondrial communication and how it impacts mitochondrial-mediated apoptosis. This thesis is divided into three results chapters. In the first results chapter, using apogossypol as a prototype tool compound, it is shown that ER membrane reorganisation occurs at the level of ER tubules but does not involve ER sheets. Moreover, further characterisation of the subcellular localisation of reorganised membranes reveal that other organelles, such as mitochondria, lysosomes, Golgi complex were not involved in ER membrane reorganisation. Next, the effect of ER membrane reorganisation with respect to mitochondrial membrane dynamics and apoptosis was studied. The results indicate that ER membrane reorganisation prevents DRP-1-mediated mitochondrial fission as well as BH3 mimetic-mediated BAX translocation, cytochrome c release and apoptosis. In the next results chapter, the objective was to examine the impact of ER membrane reorganisation modulators on apoptosis. Inhibitors of dihydroorotate dehydrogenase (DHODH), such as teriflunomide and leflunomide, not only prevent ER membrane reorganisation, but also antagonise the protective effects of the reorganised ER membranes against BH3 mimetic-mediated apoptosis. Since DHODH inhibitors antagonised ER membrane reorganisation and enhanced BH3 mimetic-mediated apoptosis, in the next chapter, the therapeutic benefits of DHODH inhibitors was explored in head and neck squamous cell carcinoma (HNSCC). The results indicate that DHODH is highly expressed in HNSCC cell lines, and genetic as well as pharmacological inhibition of DHODH reduce clonogenic survival potential in several HNSCC cells. Although targeting DHODH could be a promising strategy in HNSCC, inhibitors of DHODH do not synergise with other potential chemotherapeutic agents namely, cisplatin, A-1331852, S63845, and CB-839. Further studies are required to assess whether DHODH inhibitors will be effective as single agents, or in combination with other novel chemotherapeutic agents.

description: We use the Wide-field Infrared Survey Explorer (WISE) and the Sloan Digital Sky Survey (SDSS) to confirm a connection between dust-obscured active galactic nuclei (AGNs) and galaxy merging. Using a new, volume-limited (z ≤ 0.08) catalogue of visually selected major mergers and galaxy–galaxy interactions from the SDSS, with stellar masses above 2 × 1010 M⊙, we find that major mergers (interactions) are 5–17 (3–5) times more likely to have red [3.4] − [4.6] colours associated with dust-obscured or ‘dusty’ AGNs, compared to non-merging galaxies with similar masses. Using published fibre spectral diagnostics, we map the [3.4] − [4.6] versus [4.6] − [12] colours of different emission-line galaxies and find that one-quarter of Seyferts have colours indicative of a dusty AGN. We find that AGNs are five times more likely to be obscured when hosted by a merging galaxy, half of AGNs hosted by a merger are dusty, and we find no enhanced frequency of optical AGNs in merging over non-merging galaxies. We conclude that undetected AGNs missed at shorter wavelengths are at the heart of the ongoing AGN-merger connection debate. The vast majority of mergers hosting dusty AGNs are star forming and located at the centres of Mhalo < 1013 M⊙ groups. Assuming plausibly short-duration dusty-AGN phases, we speculate that a large fraction of gas-rich mergers experience a brief obscured AGN phase, in agreement with the strong connection between central star formation and black hole growth seen in merger simulations.
