The effect of therapy on arousal from sleep in patients with respiratory sleep disorders
Creators: name: Alqarni, Abdullah Saad
Publisher: name: Imperial College London
Year: 2022

description: Vibrotactile positional therapy (PT) is a relatively new treatment for positional obstructive sleep apnoea (POSA). It uses vibrotactile stimulus to encourage the sleeper to change position when supine. The overall aim of this thesis was to investigate the efficacy of vibrotactile PT as a clinical treatment for patients with POSA. To achieve this, different experimental approaches were used, including a systematic review and meta-analysis, a clinical trial, and a physiological study. The systematic review was carried out to evaluate the effect of vibrotactile PT on apnoea hypopnoea index (AHI), percentage of time spent in supine (%Tsupine), and patient-centred outcomes in patients with POSA compared to baseline. The results showed that vibrotactile PT was effective in reducing both AHI and %Tsupine. Although the Epworth Sleepiness Scale and the Functional Outcomes of Sleep Questionnaire minimally improved, these changes did not reach clinically important differences; however, limited data were found on quality of life (SF-36) vitality score. A prospective, three-month, multicentre, randomised, parallel, double-blind trial (The POSA Trial, ISRCTN51740863) was developed to investigate the effect of vibrotactile PT on AHI, quality of life and daytime functioning at follow-up, adjusted for the baseline, in patients with POSA compared to sham-vibrotactile PT. Baseline data (AHI, quality of life and daytime functioning) obtained from the participants recruited at the Royal Brompton Hospital are presented in the thesis. The mean baseline AHI for RBH participants was in the mild OSA category compared to the patients in the systematic review; however, a higher baseline %Tsupine was found. The baseline patient-centred outcomes were also comparable to those found in the systematic review. A physiological study in healthy participants (n=27) was carried out to investigate the effect of vibrotactile stimulus on arousability from sleep. A novel analysis method was developed to measure arousability. This included the duration from the vibrotactile stimulus to the position change using polysomnography. The results of this study showed heterogenous arousability responses to the vibrotactile stimulus with different phenotypes. Compared to males, healthy females took longer to respond to the vibrotactile stimulus and, therefore, were more resilient to arousability. In summary, the findings of this thesis have shown that vibrotactile PT devices are effective in treating patients with POSA. However, limited data on sensitive patient-centred outcomes exist. The POSA trial will provide data to address this evidence gap. Furthermore, the physiological findings in people without OSA showed that males are more arousable than females. This information may be of value when considering personalisation of clinical treatment. Future research of POSA will need to consider the arousability phenotype when planning treatment options.
Identifying the drivers of inhibitor of apoptosis protein antagonist resistance in pancreatic cancer
Creators: name: Haegeman, Caroline
Publisher: name: Imperial College London

description: Pancreatic ductal adenocarcinoma (PDAC) is the 7th leading cause of cancer related death. Deregulation of the apoptotic pathway, including upregulation of inhibitor of apoptosis proteins (IAPs), occurs at an early stage in PDAC resulting in aggressive tumours which are often resistant to therapy. Currently, use of IAP antagonists in clinical trials aims to sensitise cancer cells to apoptosis. However, these therapies show a lack of efficacy in a large proportion of the patient population. Therefore, elucidating the molecular mechanisms associated with resistance to IAP antagonists could optimise treatment strategies for PDAC. In this study, three different screening methodologies are used to identify novel resistance drivers to IAP antagonists. Firstly, a genome-wide CRISPR-Cas9 screen was conducted to identify 1025 potential genetic contributors (p<0.05) to birinapant response in the insensitive Suit-2 cell line. Secondly, two acquired resistance cell lines from Capan-1 and Panc-1 cell lines were created from prolonged treatment exposure. Differential gene expression analysis compared acquired resistance to parental cell lines to identify 494 common gene expression changes associated with resistance (P<0.05). Finally, large scale pan-cancer drug sensitivity data sets were analysed for multi-omic resistance drivers to four IAP antagonists: birinapant, LCL161, Embelin and AZD5582. This identified significant differences between IAP antagonists, with no common drivers identified for all antagonists. The three screening methods were compared to identify three birinapant resistance drivers present in all analyses: RSU1, ACVR2A and ANK2. From these findings, initial validations of several resistance drivers were conducted. These included investigations of single target knockdowns of MYC as well as the effects of ribosome biogenesis, Estrogen signalling and proteosome regulation on IAP antagonist sensitivity. Overall, cMYC silencing and BET inhibitor combinations were the most promising combinations with IAP antagonists, with significant synergies observed in several PDAC cell lines. In summary, this project successfully utilises three methodologies to uncover several novel IAP antagonist resistance drivers and suggests several rational combination targets to improve therapeutic strategies for pancreatic cancer.

description: Monodispersed strontium titanate nanoparticles were prepared and studied in detail. It is found that ~10 nm as-prepared stoichiometric nanoparticles are in a polar structural state (with possibly ferroelectric properties) over a broad temperature range. A tetragonal structure, with possible reduction of the electronic hybridization is found as the particle size is reduced. In the 10 nm particles, no change in the local Ti-off centering is seen between 20 and 300 K. The results indicate that nanoscale motifs of SrTiO3 may be utilized in data storage as assembled nano-particle arrays in applications where chemical stability, temperature stability and low toxicity are critical issues.

Natural resource managers across Australia intend to promote healthy floodplain lake ecosystems with rich diversity and composition of biota because such ecosystems provide economically valuable services to society. However, management practice of these floodplain lake ecosystems is impeded by confounding effects of anthropogenic impacts and natural climate variability in recent decades. Yet, there are a few potential biological markers available that profoundly respond to ecological effects of climate change and human disturbances. Cladoceran zooplankton plays an intermediary role in food web dynamics. They show distinct responses to changes in temperature and environmental perturbations, such as acidification, nutrient loading and salinization. The effects of temperature and land‐use changes on food web dynamics and water quality, in particular, are major concerns for shallow lowland large river floodplain lakes management in Australia. Information on zooplankton assemblages and diversity can help increase our understanding of ecological processes in a wide range of environmental exposures. The study of cladoceran fossils and their ephippia environment relationships at different temporal and spatial scales and allowed us to develop powerful inference models for degraded floodplain lake ecosystems. This consequently defines a benchmark of a shift from a naturally intact ecosystem to an ecologically poor regime. In this paper, I have made an attempt to persuade wetland managers through application of contemporary and palaeocladoceran communities to improve management practice of floodplain lake ecosystems in Australia by providing a range of examples.

Next generation mechanically deployable aero-decelerators for Mars entry
Creators: name: Peacocke, Lisa
Publisher: name: Imperial College London
Year: 2021

description: Current Mars entry vehicle technology is near its payload mass delivery limit. Mechanically deployable aero-decelerators are a next generation technology that would enable the future exploration of Mars, including human landing. Various concepts and architectures have been proposed over the years, with widely-varying mass assessments and limited technology development. A novel 6 degree-of-freedom entry trajectory simulator coupled with a structural model of the deployable elements, or ribs, has been developed and correlated against industry tools and flight data to investigate and optimise the design of mechanically deployable aero-decelerators. A major assumption of the simulator – that heatshield gores remain flat under rib deformation – has been investigated by testing ambient 3D woven carbon fabric for use as the flexible thermal protection system material, proving that conditioning can significantly improve the stiffness properties of the fabric. The design optimisation has revealed that, although deployable rib flexibility is beneficial in reducing mass and volume of the deployed ribs, an increase in peak heat flux will result. However, if mass savings from flexible ribs can be reallocated towards increasing the diameter of the entry vehicle, significant entry trajectory benefits can be gained. A set of general design principles for mechanically deployable aero-decelerators has been developed based on the optimisation investigations, including the recommendations to include at least 10 ribs to minimise drag reduction, and to increase the initial rib angle if rib flexibility is allowed to improve deceleration. In addition, the entry vehicle roll rate appears to be influenced by the number of deployable ribs. This roll instability of faceted entry vehicles is of significant concern, so a novel supersonic wind tunnel test methodology was developed to further investigate this hypothesis. The first experimental results imply that pitch and yaw attitude and instabilities are necessary pre-requisites to initiate roll during entry, and that an 8 rib test article rotates at faster rates than the 12 rib test article. Finally, a new functional relationship for the angular acceleration of entry vehicles has been proposed that it is hoped will inspire further investigations in this area.

description: The case study of a class of twenty-five fourth graders was designed to trace the growthand development in thinking about fraction ideas prior to the inception of rules and algorithmswithin the school curriculum. The project was an outgrowth of a long-term teacher developmentcollaboration between Rutgers University and the Conover Road School in Colts Neck, NJ. Twenty-five children in Mrs. Phillips' class met with a team of Rutgers researchers fifty one and one-half hour sessions during the school year. This study reports on the first seven of the twenty-five sessions focusing on fraction activities. During all sessions, children were invited to explore activities working with partners or insmall groups. They discussed their solutions and built models to illustrate their findings. Children explained and supported their ideas, first to other small groups and then to the entire class. The fourth-graders built a mathematical community in which ideas were presented, explored and debated. Four pivotal mathematical strands developed in the children's thinking. These strands included a growing understanding of 1) fraction as operator and fraction as number, (2) attention to the naming of the unit or the construction of an assimilation paradigm, (3) fraction comparisons, and (4) equivalence. The work of the children is offered as a powerful existence proof of the mathematical understanding that learners can develop before exposure to the rules and definitions presented in formal curricula.

Der lombardische Rhythmus im "Domine Deus" der h-Moll-Messe J. S. Bachs

description: Die Entdeckung von zwei bisher unbeobachteten Tönen in der autografen zweiten Geige und den Bratschenstimmen des "Domine Deus" aus der h-Moll-Messe BWV 232, die von Bach in umgekehrtem punktiertem Rhythmus notiert wurden, löst die alte Kontroverse über die rhythmische Ausführung. Die strategische Lage dieser beiden Takte und die seit langem bekannten "lombardischen" Takte im der autografen Flötenstimme machen die Einwände hinfällig, die gegen die lombardische Ausführung erhoben wurden, weil sie in der ersten Violinstimme fehlt. Weitere Beispiele zeigen, dass der lombardische Rhythmus ein Teil von Bachs Kompositionsstil in den frühen 1730er Jahren war. Er war jedoch keine plötzliche Modeerscheinung, da Bach diesen Rhythmus in späteren Parodien und Wiederholungen beibehielt. Da die von Bach an den lombardischen Rhythmus angelehnten Texte weitgehend verwandt sind, können wir weiter von einer Affinität des Affekts sprechen.

Operational moving target defences for improved power system cyber-physical security
Creators: name: Higgins, Martin
Publisher: name: Imperial College London
Year: 2021

description: In this work, we examine how Moving Target Defences (MTDs) can be enhanced to circumvent intelligent false data injection (FDI) attacks against power systems. Initially, we show how, by implementing state-of-the-art topology learning techniques, we can commit full-knowledge-equivalent FDI attacks against static power systems with no prior system knowledge. We go on to explore how naive applications of topology change, as MTDs, can be countered by unsupervised learning-based FDI attacks and how MTDs can be combined with physical watermarking to enhance system resilience. A novel intelligent attack, which incorporates dimensionality reduction and density-based spatial clustering, is developed and shown to be effective in maintaining stealth in the presence of traditional MTD strategies. In resisting this new type of attack, a novel implementation of MTD is suggested. The implementation uses physical watermarking to drive detection of traditional and intelligent FDI attacks while remaining hidden to the attackers. Following this, we outline a cyber-physical authentication strategy for use against FDI attacks. An event-triggered MTD protocol is proposed at the physical layer to complement cyber-side enhancements. This protocol applies a distributed anomaly detection scheme based on Holt-Winters seasonal forecasting in combination with MTD implemented via inductance perturbation. To conclude, we developed a cyber-physical risk assessment framework for FDI attacks. Our assessment criteria combines a weighted graph model of the networks cyber vulnerabilities with a centralised residual-based assessment of the physical system with respect to MTD. This combined approach provides a cyber-physical assessment of FDI attacks which incorporates both the likelihood of intrusion and the prospect of an attacker making stealthy change once intruded.

description: Due to the increased complexity of software development projects more and more systems are described by models. The sheer size makes it impractical to describe these systems by a single model. Instead many models are developed that provide several complementary views on the system to be developed. This however leads to a need for compositional models. This paper describes a foundational theory of model composition in form of an algebra to explicitly clarify different variants and uses of composition, their interplay with the semantics of the involved models and their composition operators.

description: Recent developments in anti-de Sitter holography point towards the association of an infinite class of covariant objects, the simplest one being codimension-one extremal volumes, with quantum computational complexity in the microscopic description. One of the defining features of these gravitational complexity proposals is describing the persistent growth of black hole interior in classical gravity. It is tempting to assume that the gravitational complexity proposals apply also to gravity outside their native anti-de Sitter setting in which case they may reveal new truths about these cases with much less understood microscopics. Recent first steps in this direction in de Sitter static patch demonstrated a very different behavior from anti-de Sitter holography deemed hyperfast growth: diverging complexification rate after a finite time. We show that this feature is not a necessity and among gravitational complexity proposals there are ones, which predict linear or exponential late-time growth behaviors for complexity in de Sitter static patches persisting classically forever.

I racconti dei Sette savi (1912) sono il suo primo tentativo di narrativa umoristico-filosofica; nella seconda edizione (1916) Bontempelli aggiunge un Dialogo metafisico e preliminare che dà al libro una tinta fantastica; lo stile del dialogo tra Talete e Solone è vicino a certe Operette morali di Leopardi. D'altra parte, Bontempelli subisce anche gli influssi di Pirandello e dell'avanguardia futurista, come si può vedere nello sviluppo del suo lavoro negli anni che seguono la Grande Guerra.

description: Quasi-static transformations, or slow quenches, of many-body quantum systems across quantum critical points create topological defects. The Kibble-Zurek mechanism regulates the appearance of defects in a local quantum system through a classical combinatorial process. However, long-range interactions disrupt the conventional Kibble-Zurek scaling and lead to a density of defects that is independent of the rate of the transformation. In this study, we analytically determine the complete full counting statistics of defects generated by slow annealing a strong long-range system across its quantum critical point. We demonstrate that the mechanism of defect generation in long-range systems is a purely quantum process with no classical equivalent. Furthermore, universality is not only observed in the defect density but also in all the moments of the distribution. Our findings can be tested on various experimental platforms, including Rydberg gases and trapped ions.

description: Using the recently proposed quantum electrodynamical formalism, we calculate the Casimir-Polder free energies and forces between the ground state atoms of Rb, Na, Cs and He${}^{\ast}$ and the plates made of Au, Si, sapphire and fused silica coated with a graphene sheet. It is shown that the graphene coating has no effect on the Casimir-Polder interaction for metallic plates, but influences significantly for plates made of dielectric materials. The influence of graphene coating increases with decreasing static dielectric permittivity of the plate material and the characteristic frequency of an atomic dynamic polarizability. Simple analytic expressions for the classical limit of the Casimir-Polder free energy and force between an atom and a graphene-coated plate are obtained. From the comparison with the results of numerical computations, the application region of these expressions is determined.

In particular, we irradiated the detectors with protons (of 0.8 and 11 MeV energy) to study the increment of leakage current and the variation of the charge collection efficiency produced by the displacement damage, and we "bombarded" the detectors with hypervelocity dust grains to measure the effect of the debris impacts. In this paper we describe the measurements and discuss the results in the context of the LOFT mission.

description: In this paper, we consider the Einstein-Maxwell-dilaton holographic model for light quarks with nonzero magnetic field and chemical potential. First, we study the phase diagrams in $T-μ$ and $T-B$ planes. We observe inverse magnetic catalysis which is consistent with the lattice QCD results. We discuss the influence of the magnetic field and chemical potential on the location of the critical end point (CEP). It is found that the magnetic field increases the critical $μ_{\scriptscriptstyle CEP}$ of the CEP in the $T-μ$ plane and the chemical potential increases the critical $B_{\scriptscriptstyle CEP}$ of the CEP in the $T-B$ plane. Second, we discuss the equations of state (EOS) with nonzero magnetic field and chemical potential. We observe that the EOS near the phase transition temperature are nonmonotonic. Then we study the energy loss with a nonzero magnetic field and chemical potential. It is found that the drag force of the heavy quark and jet quenching parameter $\hat{q}$ show an enhancement near the phase transition temperature. The peak values of drag force and $\hat{q}$ are pushed toward lower temperature with increasing $B$ or $μ$. This phenomenon is consistent with the phase transition temperature decrease with increasing $B$ or $μ$ in this holographic model. Moreover, we find that the heavy quark may lose more energy when it is perpendicular to a magnetic field which is consistent with the results of the jet quenching parameter.

description: We study the spatial properties of high-gain parametric down-conversion (PDC). From the Hamiltonian we find the Schmidt modes, apply the Bloch-Messiah reduction, and calculate analytically the measurable quantities, such as the angular distributions of photon numbers and photon-number correlations. Our approach shows that the Schmidt modes of PDC radiation can be considered the same as for the low-gain (biphoton) case while the Schmidt eigenvalues strongly depend on the parametric gain. Its validity is confirmed by comparison with several experimental results, obtained by us and by other groups.

description: After highlighting the principle and power of asteroseismology for stellar physics, we briefly emphasize some recent progress in this research for various types of stars. We give an overview of high-precision high duty-cycle space photometry of OB-type stars. Further, we update the overview of seismic estimates of stellar parameters of OB dwarfs, with specific emphasis on convective core overshoot. We discuss connections between pulsational, rotational, and magnetic variability of massive stars and end with future prospects for asteroseismology of evolved OB stars.

Wie entstand die Bach-Sammlung Mempell-Preller?
Creators: name: Schulze, Hans-Joachim
Publisher: name: Bach-Jahrbuch
Year: 2018

description: Die hier betrachteten Manuskripte werden teilweise in der Musikbibliothek der Stadt Leipzig, teilweise in der Staatsbibliothek Berlin-Dahlem verwahrt und umfassen Werke von J. S. Bach, G. Böhm, D. Buxtehude, J. P. Kellner, J. L. Krebs, P. Locatelli, J. G. Walther und anderen Komponisten. Sie gehen auf den Kantor Johann Nicolaus Mempell (1713-1747) in Apolda zurück, der möglicherweise ein Schüler von J. P. Kellner war. Johann Gottlieb Preller aus Oberroßla bei Apolda (1727-1786, ab 1753 Kantor und Organist in Dortmund) und vielleicht ein Schüler von J. N. Mempell und J. T. Krebs senior, kombinierte diese Gruppe von Handschriften mit Kopien, die er in den Jahren 1743 bis 1749 selbst angefertigt hatte. Nachfolgende Besitzer waren Daniel Friedrich Eduard Wilsing aus Wesel, ein Urenkel Prellers (bis 1854), und Max Seiffert in Berlin (bis 1904).

Interplay between multi-spin and chiral spin interactions on triangular lattice

description: We investigate the spin-$\frac{1}{2}$ nearest-neighber Heisenberg model with the four-site ring-exchange $J_4$ and chiral interaction $J_χ$ on the triangular lattice by using the variational Monte Carlo method. The $J_4$ term induces the quadratic band touching (QBT) quantum spin liquid (QSL) with only a $d+id$ spinon pairing (without hopping term), the nodal $d$-wave QSL and U(1) QSL with a finite spinon Fermi surface progressively. The effect of the chiral interaction $J_χ$ can enrich the phase diagram with two interesting chiral QSLs (topological orders) with the same quantized Chern number $\mathcal{C} = \frac{1}{2}$ and ground-state degeneracy GSD = 2, namely the U(1) chiral spin liquid (CSL) and Z$_2$ $d+id$-wave QSL. The nodal $d$-wave QSL is fragile and will turn to the Z$_2$ $d+id$ QSL with any finite $J_χ$ within our numerical calculation. However, in the process from QBT to the Z$_2$ $d+id$ QSL with the increase of $J_χ$, an exotic crossover region is found. In this region, the previous QBT state acquires a small hopping term so that it opens a small gap at the otherwise band touching points, and leads to an energy minimum which is energetically more favorable compared to another competitive local minimum from the Z$_2$ $d+id$ QSL. We dub this state as the proximate QBT QSL and it gives way to the Z$_2$ $d+id$ QSL eventually. Therefore, the cooperation of the $J_4$ and $J_χ$ terms favors mostly the Z$_2$ $d+id$-wave QSL, so that this phase occupies the largest region in the phase diagram.

description: As modeling becomes a crucial activity in software development the question may be asked whether currently used graphical representations are the best option to model systems efficiently. This position paper discusses the advantages of text-based modeling over commonly used graphical representations. It is inspired through the advent of new extensible development tools like Eclipse. The discussion is illustrated by showing a textual version of UML state machines as Eclipse plugins.

description: A method is presented for the sensing of ions by determining the concentration of corresponding salts (KCl, NaCl, MgCl2, CaCl2, FeCl3, FeSO4, AlCl3) in water, based on Fluorescence resonance energy transfer (FRET) process. The principle of the proposed sensor is based on the change of FRET efficiency between two laser dyes Acriflavine and Rhodamine B in presence of different ions (K+, Na+, Mg2+, Ca2+, Fe2+, Fe3+, Al3+). Nanodimensional clay platelet laponite was used to enhance the efficiency of the sensor.

description: Bound and resonance states of the dipole-bound anion of hydrogen cyanide HCN$^-$ are studied using a non-adiabatic pseudopotential method and the Berggren expansion technique involving bound states, decaying resonant states, and non-resonant scattering continuum. We devise an algorithm to identify the resonant states in the complex energy plane. To characterize spatial distributions of electronic wave functions, we introduce the body-fixed density and use it to assign families of resonant states into collective rotational bands. We find that the non-adiabatic coupling of electronic motion to molecular rotation results in a transition from the strong-coupling to weak-coupling regime. In the strong coupling limit, the electron moving in a subthreshold, spatially extended halo state follows the rotational motion of the molecule. Above the ionization threshold, electron's motion in a resonance state becomes largely decoupled from molecular rotation. Widths of resonance-band members depend primarily on the electron orbital angular momentum.
