description: Arming of oncolytic viruses with tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been shown as a viable approach to increase the antitumor efficacy in melanoma. However, melanoma cells may be partially or completely resistant to TRAIL or develop TRAIL resistance, thus counteracting the antitumor efficiency of TRAIL-armed oncolytic viruses. Recently, we found that TRAIL resistance in melanoma cells can be overcome by inhibition of antiapoptotic Bcl-2 protein myeloid cell leukemia 1 (Mcl-1). Here, we investigated whether the cytotoxicity of AdV-TRAIL, an oncolytic adenovirus, which expresses TRAIL after induction by doxycycline (Dox), can be improved in melanoma cells by silencing of Mcl-1. Two melanoma cell lines, the TRAIL-resistant MeWo and the TRAIL-sensitive Mel-HO were investigated. Treatment of both cell lines with AdV-TRAIL resulted in a decrease of cell viability, which was caused by an increase of apoptosis and necrosis. The proapoptotic effects were dependent on induction of TRAIL by Dox and were more pronounced in Mel-HO than in MeWo cells. SiRNA-mediated silencing of Mcl-1 resulted in a further significant decrease of cell viability and a further increase of apoptosis and necrosis in AdV-TRAIL-infected MeWo and Mel-HO cells. However, while in absolute terms, the effects were more pronounced in Mel-HO cells, in relative terms, they were stronger in MeWo cells. These results show that silencing of Mcl-1 represents a suitable approach to increase the cytotoxicity of a TRAIL-armed oncolytic adenovirus in melanoma cells.

Wireless interactions between unmanned aerial vehicles and sensor nodes
Creators: name: Qin, Yuan
Publisher: name: Imperial College London
Year: 2019

description: Recent advances in low power communication, power electronics, and unmanned aerial vehicles (UAV) technologies enable introducing UAVs to wireless sensor networks (WSN) applications, promising to extend the applicability of the Internet of Things concept to remote and hazardous environments. UAVs, as a data link, can remove the barrier of acquiring sensing information from otherwise disconnected devices. As a power link, meanwhile, continuous operation of sensors may be supported through wireless charging. However, design of low power communication protocols considering mobility remains an open issue. There are scant reported experiments of using UAVs to carry transmit coils for wireless charging, nor navigation solutions for UAVs to find sensor nodes requiring charging. This thesis proposes solutions to the challenges of communication and power linkages in this context. A cross-layer UAV integrated WSN protocol (UIWP) is designed and implemented for wireless communications between UAV and terrestrial wireless sensors. Experimental evaluation shows the proposed protocol to have good energy efficiency, low latency and high reliability. To boost the communication bit rate, dynamic switching between the IEEE 802.15.4 and Bluetooth Low Energy physical layers are implemented within UIWP, where the Bluetooth mode consumes about half the time and energy for transmitting the same amount of data. To solve the problem of navigating the UAV to the optimal charging point, an energy efficient sensor node was designed and built incorporating ultra-wide band technology to improve ranging. Its corresponding energy models were developed to determine charging frequency. Extended Kalman filter and navigation control algorithms are proposed for UAV positioning and navigation. The algorithms fuse sensing data, telemetry information and communication data to control the flight of the UAV, intended to achieve centimetre scale accuracy.

description: We implement and benchmark the frozen core approximation, a technique commonly adopted in electronic structure theory to reduce the computational cost by means of mathematically fixing the chemically inactive core electron states. The accuracy and efficiency of this approach are well controlled by a single parameter, the number of frozen orbitals. Explicit corrections for the frozen core orbitals and the unfrozen valence orbitals are introduced, safeguarding against seemingly minor numerical deviations from the assumed orthonormality conditions of the basis functions. A speedup of over two-fold can be achieved for the diagonalization step in all-electron density-functional theory simulations containing heavy elements, without any accuracy degradation in terms of the electron density, total energy, and atomic forces. This is demonstrated in a benchmark study covering 103 materials across the periodic table, and a large-scale simulation of CsPbBr3 with 2,560 atoms. Our study provides a rigorous benchmark of the precision of the frozen core approximation (sub-meV per atom for frozen core orbitals below -200 eV) for a wide range of test cases and for chemical elements ranging from Li to Po. The algorithms discussed here are implemented in the open-source Electronic Structure Infrastructure software package.
Fabrication and aplications of graphene hollow fibre membranes
Creators: name: Chi, Yunsi
Publisher: name: Imperial College London
Year: 2019

description: Graphene has attracted vast amount of research in the last decade. Attributed to its sp2 hybridisation, graphene is chemically inert, making it an ideal material to be used in extremely harsh conditions. Graphene’s ultra-thin property also makes it an ideal material for membrane separation because permeation is inversely proportional to membrane thickness. While many studies have been carried out on graphene membranes, scaling up remains a key challenge, designing graphene membrane in a geometry which favours module assembly is strongly desired. Furthermore, chemical resistance of metallic membrane can be improved by integrating graphene as a protective barrier. In this thesis, the fabrication and applications of the prepared graphene hollow fibre membranes are explored. Firstly, graphene protected nickel hollow fibre membrane was developed and demonstrated improved chemical resistance compared to the non-protected membrane. Its application was further explored in the production of nanoparticles. Pristine graphene membranes supported on porous ceramic hollow fibre was successfully prepared via the sacrificial layer assisted chemical vapour deposition (CVD) approach. A dense metal sacrificial layer was deposited on the hollow fibre support using electroless plating. After successful graphene growth, this sacrificial layer was removed while the ceramic hollow fibre remained intact to act as the support. Both copper and nickel sacrificial layers were explored. When copper was used, copper dewetting on ceramic surface was observed during high temperature synthesis, which hindered good quality graphene growth. The membrane showed compaction where the permeation flux declined during filtration. Nickel was then investigated to prevent metal dewetting. A dense and continuous nickel sacrificial layer was formed, which was suitable for high-quality CVD graphene synthesis. Finally, pristine graphene membrane supported on ceramic hollow fibre was realised after metal etching, demonstrating reasonable flux and rejection. This study thus presents the successful engineering of graphene hollow fibre membranes suitable for industry scale-up.
Calculation of frequency-dependent parameters of underground power cables with finite element method
Creators: name: Yin, Yanan
Publisher: name: University of British Columbia
Year: 2011

description: In this thesis, the finite element method (FEM) is applied to the calculation of frequency-dependent series impedances and shunt capacitances of underground power cables. The principal equations describing the quasi-magnetic fields and static electric fields are solved with FEM based on the Galerkin technique. The Js method and the loss-energy method are derived to calculate the impedances of a multiconductor system from its field solution, and the energy method and the surface charge method are derived to calculate the capacitances. With a single-core (SC) coaxial cable, the suitability of quadratic isoparametric elements and high-order simplex elements are studied, and a suitable division scheme is suggested for the auto-mesh program. The conventional FEM with a field truncation boundary is applied to the impedance calculation of buried SC cables. Suitable locations for the field truncation boundary and division schemes in the earth are studied. The results show that rb ≥ 12[symbol omitted] is required to obtain accurate impedances of shallowly buried cables with the conventional FEM. This requires a large solution region in the earth at low frequencies. A new technique based on the perturbation concept is proposed to reduce the solution region in the earth. Comparisons between the results from the conventional FEM and from the proposed technique with a significantly reduced solution region in the earth show good agreement. In the case studies, the FEM is applied to the parameter calculation of multiphase SC cables, PT cables, sector-shaped cables, and stranded conductors. The numerical results are compared with those from analytical formulas.

description: We study the Fano effect and the visibility of the Aharonov-Bohm oscillations for a mesoscopic interferometer with an embedded quantum dot in the presence of a nearby second dot. When the electron-electron interaction between the two dots is considered the nearby dot acts as a charge detector. We compute the currents through the interferometer and detector within the Keldysh formalism and the self-energy of the non-equilibrium Green functions is found up to the second order in the interaction strength. The current formula contains a correction to the Landauer-B\"{uttiker} formula. Its contribution to transport and dephasing is discussed. As the bias applied on the detector is increased, the amplitude of both the Fano resonance and Aharonov-Bohm oscillations are considerably reduced due to controlled dephasing. This result is explained by analyzing the behavior of the imaginary part of the self-energy as a function of energy and bias. We investigate as well the role of the ring-dot coupling. Our theoretical results are consistent to the experimental observation of Buks {\it et al.} [Nature {\bf 391}, 871 (1998)].

Implementation of model predictive control strategies in grid-tied power electronic voltage source converters
Creators: name: Rodriguez Bernuz, Joan Marc
Publisher: name: Imperial College London
Year: 2019

description: This thesis explores a different approach in the use of MPC applied to grid-tied converters, which aims to improve their performance, either during abnormal operating conditions or by exploiting the full potential of the converter in steady-state. The design of the MPC is firstly introduced in a single-phase converter. Although this device is mostly used in low voltage and low power applications, this analysis brings insight into the design of more complex converter topologies. Besides, the study of the single-phase converter presents interesting challenges due to the pulsating power of the single-phase system. It is found that the nonlinear behaviour of the converter, even at a high level of abstraction, leads to a formulation of the MPC that requires the use of nonlinear solvers. Consequently, the time-to-resolution of the optimisation problem becomes cumbersome, and a strategy to reduce the overall computation burden is sought. Given that the steady-state operation of grid-tied converters is based on sinusoidal trajectories, a simplification approach where the converter is linearised over LTV trajectories is introduced. This approach is not common in the control of power converters but it has been successfully implemented in other fields such as in the automotive industry. The results obtained prove the good performance of this approach and the controller is validated in a laboratory test-bench. The benefits of the MPC strategy applied to a MMC-HVDC converter are also discussed. The algorithm is applied to a single-phase structure to facilitate its analysis. The results considering HVDC-scaled parameters suggest potential benefits in terms of hardware optimisation. It is shown that the predictive controller can enhance the operating area of the converter by naturally combining different known harmonic injection techniques. Finally, this document also presents a preliminary investigation of the coordination of the different curtailment mechanisms integrated into a RE system using an MPC algorithm.

description: We have studied the masse spectra for the $cc\bar{b}\bar{b}$/$bb\bar{c}\bar{c}$ tetraquark states with quantum numbers $J^{P}=0^{\pm},1^{\pm}$, and $2^{+}$. We systematically construct the interpolating currents with various spin-parity quantum numbers and calculate their two-point correlation functions in the framework of QCD moment sum rule method. Our calculations show that the masses are about $12.3-12.4$ GeV for the positive parity $cc\bar{b}\bar{b}$ tetraquark ground states with $J^{P}=0^+, 1^+, 2^+$, while $12.8-13.1$ GeV for the negative parity channels with $J^{P}=0^-, 1^-$. The mass predictions for the positive parity $cc\bar{b}\bar{b}$ ground states are lower than the $B_{c}B_{c}$ threshold, implying that these tetraquarks can only decay via weak interaction and thus are expected to be stable and narrow.

We find two important limiting cases: a scale-free degree distribution and a finite-scale degree distribution. The size of the space of allowed simple networks given these distribution is evaluated in the large network limit. Results are compared with simulations of algorithms generating these networks.

The preservation of lipid biosignatures in iron-rich environments on mars
Creators: name: Tan, Jonathan
Publisher: name: Imperial College London
Year: 2020

description: Past life on Mars, should it have existed, would have left behind fossilised organic biosignatures. Sample selection strategies for current and future life detection missions to Mars require an understanding of the processes that control the preservation, degradation, and detection of diagnostic organic fossil biosignatures in Martian environments over geological time. These include the deleterious effects of radiation, the increased temperatures and pressures associated with burial in the Martian subsurface, and the interactions between organic matter and any oxidising minerals in the depositional environment. In particular, iron minerals dominate the Martian surface environment, and thus any sample selection strategies must consider the effects of iron minerals on the preservation of any potential biosignatures. In this thesis, the preservation of lipid biosignatures are investigated in a variety of iron-rich environments through the use of terrestrial analogues, including iron-rich acid streams, and circumneutral iron-rich bog systems. It was revealed that lipid biosignatures survive the initial stages of diagenesis in acid stream environments. Lipids were found to be concentrated in mineral layers that are indicative of high water availabilities such as goethite, as these conditions are indicators of more habitable environments. To study the later stages of diagenesis and the chemical effects of long-term storage in iron-rich environments, a novel technique was developed that involved artificial maturation via hydrous pyrolysis and computer-based kinetic modelling. It was discovered that if any solvent-extractable lipids survived late stage diagenesis, they would record biogenic patterns in their lipid profiles. However, the kinetics of the lipid degradation reaction suggested that lipids were not expected to survive for billions of years necessary for detection at the present day. This quantitative nature of this artificial maturation technique also allows for a quantitative means by which the preservation potential of various Mars-analogue environments can be compared. Thermal extraction experiments found that insoluble, macromolecular organic matter could survive long-term diagenesis and be detected, as long as oxidising minerals such as goethite and jarosite could be removed from the samples prior to analysis. The findings of this thesis can inform sample selection strategies on Mars, both in terms of the iron-rich environments in which lipids are most likely to be preserved, as well as the type of techniques that might be the most appropriate life detection.

Energy conserving compatible finite element methods for numerical weather prediction
Creators: name: Wimmer, Golo Albert
Publisher: name: Imperial College London
Year: 2020

description: The compatible finite element method has recently gained an increased interest in numerical weather prediction, as it allows for higher order discretisations and more general meshes, thus avoiding the parallel computing issues associated with grid poles. Further, it can be seen as a finite element extension of the Arakawa finite difference C grid. A dynamical core based on it is currently in development at the UK Met Office, due to replace the current finite difference latitude longitude grid discretisation. In this thesis, we focus on compatible finite element discretisations that are energy conserving, which is an important property in particular for climate simulations. This is achieved using a Hamiltonian framework, where energy conservation is expressed via the antisymmetry of a Poisson bracket that underlies the governing equations. In order to achieve an improved field development, we newly incorporate into the Poisson bracket Discontinuous Galerkin upwind and Streamline Upwind Petrov Galerkin stabilisation methods for the thermal, density related, and vorticity field equations. The energy conserving property is validated by coupling the upwind-stabilised spatial discretisations to an energy conserving time discretisation. Further, the discretisations are demonstrated to lead to an improved field development with respect to stability for the 2D and 3D dry compressible Euler, rotating shallow water, and thermal rotating shallow water equations.

description: The Langevin equation (LE) for the one-dimensional relativistic Brownian motion is derived from a microscopic collision model. The model assumes that a heavy point-like Brownian particle interacts with the lighter heat bath particles via elastic hard-core collisions. First, the commonly known, non-relativistic LE is deduced from this model, by taking into account the non-relativistic conservation laws for momentum and kinetic energy. Subsequently, this procedure is generalized to the relativistic case. There, it is found that the relativistic stochastic force is still $\gd$-correlated (white noise) but does \emph{no} longer correspond to a Gaussian white noise process. Explicit results for the friction and momentum-space diffusion coefficients are presented and discussed.

description: The recently discovered kagome metal series $A$V$_3$Sb$_5$ ($A$=K, Rb, Cs) exhibits topologically nontrivial band structures, chiral charge order and superconductivity, presenting a unique platform for realizing exotic electronic states. The nature of the superconducting state and the corresponding pairing symmetry are key questions that demand experimental clarification. Here, using a technique based on the tunneling diode oscillator, the magnetic penetration depth $Δλ(T)$ of CsV$_3$Sb$_5$ was measured down to 0.07 K. A clear exponential behavior in $Δλ(T)$ with marked deviations from a $T$ or $T^2$ temperature dependence is observed at low temperatures, indicating a deficiency of nodal quasiparticles. Temperature dependence of the superfluid density and electronic specific heat can be described by two-gap $s$-wave superconductivity, consistent with the presence of multiple Fermi surfaces in CsV$_3$Sb$_5$. These results evidence nodeless superconductivity in CsV$_3$Sb$_5$ under ambient pressure, and constrain the allowed pairing symmetry.

description: Slides from the webinar "Introduction to Git" that took place on December 7, 2021, 10:00 to 11:30, online, as part of the event series "Research Data Management in Austria". Description: You have heard of GitHub, or GitLab, but are not sure whether such git-based systems are suitable for you? Version Control Systems facilitate effective collaboration between people. Although these tools are mostly used in the field of Software Engineering, they are not limited to this use case. The aim of this workshop is to learn how to manage your code, data or even text documents, so that you don’t lose track of versions, and can share it with others. You will learn about the basic concepts of git and tools that support researchers in working with git repositories. After a discussion of the theoretical content, practical examples will demonstrate how to efficiently work with the existing GitLab instance operated by the TU Wien. The practical part will also contain scenarios to demonstrate how to avoid or fix common pitfalls. Presenters - Florian Wörister, TU Wien. Florian Wörister is a developer and staff member at the Center for Research Data Management at TU Wien. - Alexander Spinn, Universität Innsbruck. Alexander Spinn is a staff member at the ZID, department Web- and Information Systems.

Acquiring a word through the speaker's false-belief
Creators: name: Stojnić, Gala
Publisher: name: No Publisher Supplied
Year: 2021

description: This work bridges two major areas of the cognitive development research–Theory of Mind (ToM) development and word learning. Specifically, I test the idea that ToM is a necessary factor in early word acquisition process, as it helps young learners form a hypothesis about what the most likely referent of a novel label might be.The idea that ToM is an important factor that young children use to select a candidate referent of a novel label is largely inspired by social approaches to word learning and word meaning (e.g. Baldwin, 1991; Cartmill et al., 2013; Grice, 1969). Critically, we postulate that the nature of early ToM that underlies this process is meta-representational, i.e. it allows for representing genuine propositional attitudes such as beliefs (e.g. Leslie, 1987). We call this developmental continuity hypothesis. An opposing view (dual-systems hypothesis) postulates that ToM lacks the meta-representational structure prior to the age of four, hence it cannot adequately account for various cases that require flexible mental states reasoning, such as reasoning about identity false-beliefs (e.g. Butterfill & Apperly, 2013). Here, we test these opposing hypotheses by asking whether young children (prior to the age of four) would succeed on a task that required them to map a label onto its referent by correcting for the speaker’s identity false-belief. If children could attribute these types of beliefs prior to the age of four and, moreover, use them to learn words this would provide a compelling support in favor of developmental continuity of metarepresentational ToM.To test these hypotheses, I developed a new naming false-belief task, which requires subjects to point to the correct referent of a novel label (a proper name or a common noun), where the only way to infer who the referent is, is through an agent’s identity false-belief. I conducted a set of experiments with young 3-year-olds and 2.5-year olds, where I employ this method to show that at least by the age of 3, children are capable of mapping a label and its referent by correcting for the speaker’s identity false-belief. This provides compelling evidence in support of developmental continuity of metarepresentational ToM. Moreover, it demonstrates that young word learners attend to the speaker’s epistemic states to narrow down the space of a word’s possible meanings, which suggests strong mentalism of the word learning process.
Cosmic-ray positron fraction measurement from 1 to 30 GeV with AMS-01

description: A measurement of the cosmic ray positron fraction e+/(e+ + e-) in the energy range of 1-30 GeV is presented. The measurement is based on data taken by the AMS-01 experiment during its 10 day Space Shuttle flight in June 1998. A proton background suppression on the order of 10^6 is reached by identifying converted bremsstrahlung photons emitted from positrons.

Texture transitions in binary mixtures of 6OBAC with compounds of its homologous series

description: Recently we have observed in compounds of the 4,n-alkyloxybenzoic acid series, with the homologous index n ranging from 6 to 9, a texture transition in the nematic range which subdivides the nematic phase in two sub-phases displaying different textures in polarised light analysis. To investigate a persistence of texture transitions in nematic phases, we prepared binary mixtures of 4,6-alkyloxybenzoic acid (6OBAC) with other members (7-,8-,9-,12-, 16OBAC) of its homologous series. Binary mixtures exhibit a broadening in the temperature ranges of both smectic and nematic phases. A nematic temperature range of 75 C is observed. In the nematic phase, in spite of the microscopic disorder introduced by mixing two components, the polarised light optics analysis of the liquid crystal cells reveals a texture transition. In the case of the binary mixture of 6OBAC with 12OBAC and with 16OBAC, that is of compounds with monomers of rather different lengths, the texture transition temperature is not homogeneous in the cell, probably due to a local variation in the relative concentrations of compounds.

description: Two paradigms were employed to disentangle information processing from executive motor inhibition in adults with Developmental Coordination Disorder (DCD). Choice Reaction and Stop Signal Tasks were compared between 13 adults fulfilling DSM-5 DCD criteria and 42 typically developing adults. Additional analyses included 16 probable DCD (pDCD) participants, who had motor difficulties but did not fulfil DSM-5 criteria. Analyses employed frequentist and Bayesian modeling. While DCD+pDCD showed slower reaction times and difficulty initiating Go responses, no impairments in Stop actions were found. These findings indicated no executive deficit in DCD, suggesting that previous results may be explained by inefficient information processing.

description: We present [SII] images of the HH 30 and HL/XZ Tau region obtained at two epochs, as well as long-slit optical spectroscopy of the HH 30 jet. We measured proper motions of about 100-300 km/s for the HH 30 jet and counterjet, and of about 120 km/s for the HL Tau jet. Inclination angles with respect to the plane of the sky are 0-40 deg for the HH 30 jet and 60 deg for the HL Tau jet. Comparison with previous observations suggests that most of the jet knots consist of persisting structures. Also, we corroborate that the HH 30-N knots correspond to the head of the HH 30 jet. The overall HH 30 jet structure can be well described by a wiggling ballistic jet, arising either by the orbital motion of the jet source around a primary or by precession of the jet axis because of the tidal effects of a companion. In the first scenario, the orbital period would be 53 yr and the total mass 0.25-2 solar masses. In the precession scenario, the mass of the jet source would be 0.1-1 solar masses, the orbital period <1 yr, and the mass of the companion less than a few times 0.01 solar masses, thus being a substellar object or a giant exoplanet. In both scenarios a binary system with a separation <18 AU (<0.13 arcsec) is required. Since the radius of the flared disk observed with the HST is about 250 AU, we conclude that this disk appears to be circumbinary rather than circumstellar, suggesting that the search for the collimating agent of the HH 30 jet should be carried out at much smaller scales.
