LS Peg: A Low-Inclination SW Sextantis-Type Cataclysmic Binary with High-Velocity Balmer Emission Line Wings

description: We present time-resolved spectroscopy and photometry of the bright cataclysmic variable LS Peg (= S193). The Balmer lines exhibit broad, asymmetric wings Doppler-shifted by about 2000 km/s at the edges, while the HeI lines show phase-dependent absorption features strikingly similar to SW Sextantis stars, as well as emission through most of the phase. The CIII/NIII emission blend does not show any phase dependence. From velocities of Halpha emission lines, we determine an orbital period of 0.174774 +/- 0.000003 d (= 4.1946 h), which agrees with Szkody's (1995) value of approximately 4.2 hours. No stable photometric signal was found at the orbital period. A non-coherent quasi-periodic photometric signal was seen at a period of 20.7 +/- 0.3 min. The high-velocity Balmer wings most probably arise from a stream re-impact point close to the white dwarf. We present simulated spectra based on a kinematic model similar to the modified disk-overflow scenario of Hellier & Robinson (1994). The models reproduce the broad line wings, though some other details are unexplained. Using an estimate of dynamical phase based on the model, we show that the phasing of the emission- and absorption-line variations is consistent with that in (eclipsing) SW Sex stars. We therefore identify LS Peg as a low-inclination SW Sex star. Our model suggests i = 30 deg, and the observed absence of any photometric signal at the orbital frequency establishes i < 60 deg. This constraint puts a severe strain on interpretations of the SW Sex phenomenon which rely on disk structures lying slightly out of the orbital plane.

An experimental study in the variation of the near-circular polarisation properties in Scarabaeoidae beetles
Creators: name: Carter, Ian Edward
Publisher: name: Imperial College London
Year: 2017

description: The scientific study of structural colour in nature dates back over 300 years. The structural colours being observed are a result of millions of years of evolution. It occurs in many different forms in nature from diffraction gratings to interference from multi layered structures and from plants to cephalopods. This thesis focuses on the near circularly polarised (CP) reflection from the helicoidally arranged chitin within the shells of selected beetles from the Scarabaeoidae superfamily. An experimental setup was refined in order to measure broadband CP light in reflection from the beetles. A large variation in the left CP reflection was seen both within and between species, genera, subfamilies and families. This included broadband reflection from silver coloured beetles to narrower reflection of dominant green colour (other colours were observed). A wide variety of spectral shapes were observed including single wavelength peaks, multiple oscillations and peaks far apart. In the Chrysina genus several new species were observed to reflect both right and left CP light. Several perturbations of the CP reflection were modelled based upon Berreman calculus. Further to the CP measurements electron, atomic force and scanning near-field optical microscope images were taken of both the helicoidal structure and surface of the beetles. A fuller description of the polarisation of the reflected near CP light from the beetles’ shells was obtained using a broadband Mueller Matrix (MM) ellipsometer, which was built and designed using liquid crystal variable retarders. From the MMs, the ellipticity, the degree of polarisation and azimuth angle were calculated. As with the CP measurements large variations were observed from highly polarised metallic to less polarised matt specimens. This study of the beetle optical properties will help to inspire the design of various optical devices as well as the further biological investigation into beetles’ polarised vision.

description: When facing complex mesoscale network structures, it is generally believed that (null) models encoding the modular organization of nodes must be employed. The present paper focuses on two block structures that characterize the mesoscale organization of many real-world networks, i.e. the bow-tie and the core-periphery ones. Our analysis shows that constraining the network degree sequence is often enough to reproduce such structures, as confirmed by model selection criteria as AIC or BIC. As a byproduct, our paper enriches the toolbox for the analysis of bipartite networks - still far from being complete. The aforementioned structures, in fact, partition the networks into asymmetric blocks characterized by binary, directed connections, thus calling for the extension of a recently-proposed method to randomize undirected, bipartite networks to the directed case.

Rectifier design for optimisation of multi-MHz inductive power transfer systems
Creators: name: Kkelis, George
Publisher: name: Imperial College London
Year: 2017

description: This thesis presents the optimisation of multi-MHz inductive power transfer (IPT) systems through rectifier analysis and design. IPT systems operating in the multi-MHz frequency range utilise air core coils which allow greater mobility between transmitter and receiver than systems utilising ferrite in their coils. While high through-air efficiencies can be achieved with both air core and ferrite core coils, the power electronic topologies used in air core IPT systems tend to be more sensitive to variations in output load and coupling between the coils. Therefore, while good system efficiencies can be achieved with multi-MHz IPT systems the spectrum of operating conditions can be limited. The work presented in this thesis identified rectifier properties that overcome the aforementioned limitations allowing operation over a broad range of IPT conditions. From IPT theory the requirements for rectifier integration in multi-MHz systems were defined and a rectifier design method was developed. Rectifier topologies capable of operation in the multi-MHz frequency range, namely Class-D and Class-E topologies, were studied in detail and a generalised analysis for Class-E topologies is presented. A hybrid Class-E half wave low dv/dt topology is introduced and compared with the conventional Class-D and Class-E rectifier topologies. From the analysis, it is shown that the hybrid Class-E rectifier provides an extra degree of design freedom which enables optimal IPT operation over a wider range of operating conditions. Furthermore, it is shown that by designing both the hybrid and the current driven Class-E rectifiers to operate below resonance provides a low deviation input reactance and inherent output voltage regulation with output load allowing efficient IPT operation over wider dc load range than would otherwise be achieved. The results of the rectifier analysis were verified through comparative and application led case studies. The highlight of the comparative case studies was the achievement of a receiving end efficiency of 94% when utilising the hybrid Class-E rectifier. The application led case studies demonstrated a dc/dc converter with inherent output voltage regulation operating at 6.78 MHz and the development of a hybrid Class-E rectifier in a 13.56 MHz wireless quadcopter powering system capable of operating with large variations in coupling between transmitting and receiving coils.

description: We use self-consistent N-body models, in conjunction with models of test particles moving in galaxy potentials, to explore the initial effects of interactions on the rotation curves of spiral galaxies. Using nearly self-consistent disk/bulge/halo galaxy models (Kuijken & Dubinski 1995), we simulate the first pass of galaxies on nearly parabolic orbits; we vary orbit inclinations, galaxy halo masses and impact parameters. For each simulation, we mimic observed rotation curves of the model galaxies. Transient interaction-induced features of the curves include distinctly rising or falling profiles at large radii and pronounced bumps in the central regions. Remarkably similar features occur in our statistical sample of optical emission-line rotation curves of spiral galaxies in tight pairs and n-tuples.

description: The presented research focuses on innovative additive manufacturing platforms and pharmaceutical formulations to improve the efficacy of the delivered drug. Drug discovery is a time-consuming and expensive process costing approximately US $1.8 billion and involves two major steps namely target identification and lead optimization. 90% of drugs currently in the pipeline and 36% marketed drugs fall in one of the two biopharmaceutical classes suffering poor aqueous solubility (BCS-II, and IV). The development of supersaturating drug delivery systems such as amorphous solid dispersions and pharmaceutical cocrystals which stabilize the drug in their high-energy or other rapidly dissolving forms while maintaining a sustained level of supersaturation over the luminal surfaces has proven efficient in solving the problem at hand. Further, with the advances in additive manufacturing processes, 3D printing personalized medicine, rapid prototyping of formulations, and added versatility of designing structures to improve the efficacy of the delivered drug have become a possibility. Here we show the utility of hot-melt extrusion and 3D printing individually and synergistically in manufacturing amorphous solid dispersions and cocrystal compositions with improved in vitro performance and stability. The conducted research investigated the influence of different processing parameters and formulation variables involved in fused deposition modeling 3D printing and selective laser sintering processes on the solid-state, stability, and quality of the 3D amorphous solid dispersions and hot-melt extruded pharmaceutical cocrystals for challenging drugs. From the conducted research, results, and observations it can be concluded that fused deposition modeling and selective laser sintering can be used for manufacturing pharmaceutical dosage forms containing amorphous solid dispersions of heat-sensitive, light-sensitive and poor glass forming drugs where the release of the drug from the dosage forms can modulate by controlling formulation and processing variables. Moreover, pharmaceutical cocrystals of heat-sensitive drugs with poor glass-forming ability manufactured using polymer-assisted hot-melt extrusion processing can be engineered to show a pH-dependent targeted release to improve their stability and performance in vitro.

description: In a previous paper (Veron et al. 1997) we presented medium resolution (3.4 A FWHM) spectroscopic observations of 15 "transition objects", selected for having an ambiguous location in the Veilleux & Osterbrock (1987) diagnostic diagrams, and showed that most of them were in fact "composite", this being due to the simultaneous presence on the slit of both a Seyfert or Liner nucleus and a HII region. Here, we report new spectroscopic observations of 53 emission-line galaxies with a "transition" spectrum, bringing up to 61 the total number of observed objects in an unbiased sample of 88 "transition objects". Almost all of the observed galaxies have a "composite" nature, confirming the finding that true "transition" spectra may not exist at all. By eliminating "composite objects" from the diagnostic diagrams, a clear separation between the different classes of nuclear emission-line regions (Seyfert 2s, Liners and HII regions) becomes apparent; by restricting the volume occupied by the different line-emitting regions in the 3-dimensional diagnostic diagrams, we are also restricting the range of possible physical parameters in these regions. There seems to be no continuity between Seyfert 2s and Liners, the two classes occupying distinct volumes in the 3-dimensional space defined by [OIII]5007/Hbeta, [NII]6583/Halpha, and [OI]6300/Halpha.

description: In order to overcome the emission of carcinogenic ‘polycyclic aromatic hydrocarbon’ from aromatic oils, which are restricted in European countries since 2010, various efforts have been made to replace the aromatic oil in rubber-based compounds either fully or partially. Liquid isoprene rubber (LIR) was used as a reactive plasticizer in natural rubber (NR) compound at different loadings (2, 4, 6 and 8 phr) and its effect on viscosity, curing characteristics and physico-mechanical properties. The results were compared with those of the control compound containing conventional aromatic oil as plasticizer. The minimum torque for the control compound was 0.33 dNm and that for LIR based compounds ranged between 0.16 and 0.56 dNm. The LIR based compounds exhibited a slightly higher Mooney viscosity but offered the same scorch safety. The results support the utility of LIR as a promising alternative as revealed by the comparable rheological and physico-mechanical properties that are attained with the usage of appropriate quantity of LIR, unlike the other alternatives of the previous investigations that usually showed a difference in the properties

description: We present sensitive, high resolution Very Long Baseline Array (VLBA) observations of the central 0.3 arcsec of PKS 2322-123 at 1.3 and 5 GHz. These observations reveal straight and symmetric jets emerging from both sides of an inverted spectrum core. The 21 cm line of atomic hydrogen is detected in absorption against the core and eastern jet with substantial opacities, but is not seen towards the equally strong western jet. Both a narrow (110 km/s FWHM) and a very broad (735 km/s FWHM) line are seen, although the very broad line is seen only against the core. Both lines are redshifted (~220 +/- 100 km/s) with respect to the systemic velocity. The most likely explanation for the observed HI kinematics are an atomic torus centered on the nucleus with considerable turbulence and inward streaming motions. The scale height of this torus is less than 20 pc. Though rare in flux limited samples of compact radio sources, symmetric parsec-scale structure appears nearly ubiquitous among radio galaxies with HI absorption, probably because they are viewed more nearly edge-on through the torus.

description: We present optical identifications and redshifts for seventeen new high-redshift radio sources. Fifteen of these sources are radio galaxies; the remaining two are high-redshift, steep-spectrum, radio-loud quasars. These objects were discovered as part of an ongoing study of compact (theta < 10 arcsec), moderately steep spectrum (alpha(1.4 GHz;4.8 GHz) > 0.75, S(nu) ~ nu^(-alpha)) sources from the MIT-Green Bank (MG) radio catalog (S(5 GHz) > 50 mJy). Spectra for the optical counterparts were obtained at the W.M. Keck Telescopes and are among the optically faintest radio galaxies thus far identified. Redshifts range between 0.3 and 3.6, with thirteen of the seventeen at redshifts greater than 1.5. Combining these new radio galaxies with two published MG radio galaxy spectra, we synthesize a composite MG radio galaxy spectrum and discuss the properties of these galaxies in comparison to other, more powerful, radio galaxies at similar redshifts. We suggest a radio power-ionization state relation.

Association of monocyte activation and microbial translocation with clinical outcomes in patients with cirrhosis
Creators: name: Gurney, Stefan
Publisher: name: Imperial College London
Year: 2016

description: The liver is interposed between the portal and systemic circulations and enriched by a pool of specialised immune cells and its pivotal role in immune defence is increasingly recognised. Cirrhosis disrupts the architecture of the hepatic sinusoidal network, hindering liver immune surveillance function. Coupled with alterations in the gut microbiome and decreased intestinal barrier function, impaired local immunity favours translocation of pattern associated molecular patterns (PAMPs) from the gut. PAMPs activate Toll-like receptors (TLRs), widely expressed in the liver. TLR4 ligation induces chronic inflammation and activates hepatic fibroblasts accelerating cirrhosis. The net effect is a paradoxical syndrome of systemic inflammation and susceptibility to infection, termed: cirrhosis-associated immune deficiency (CAID). Bacterial infections are associated with a four-fold increase in mortality in cirrhosis and may precipitate acute–on-chronic liver failure (ACLF). Prompt diagnosis, risk stratification and aggressive treatment of bacterial infections may improve survival in these patients. I designed an observational pilot study using a biomarker panel, composed of soluble and cell surface markers of immune activation and surrogate markers of bacterial translocation to test the following hypotheses: 1) The biomarker panel would be associated with disease progression in cirrhosis. 2) The biomarker panel would identify bacterial infection in patients with cirrhosis. I demonstrated evidence of monocyte activation and bacterial translocation in cirrhotic patients as compared to healthy controls. Two soluble plasma biomarkers (sTREM-1 and sCD163) were associated with increasing disease severity and identified proven infection with higher accuracy than C-reactive protein in the study population. Increased plasma sTREM-1 identified cirrhotic patients at risk of adverse outcomes: ACLF and death. Univariate Cox regression demonstrated a significant association between sTREM-1 and mortality at 2 years (Hazard Ratio: 1.002) A multivariate Cox regression model did not confirm an independent association between sTREM-1 and 2-year mortality.

New ways to control Shigella infection in the zebrafish model
Creators: name: Willis, Alexandra
Publisher: name: Imperial College London
Year: 2017

description: Shigella flexneri is an invasive bacterial pathogen and inflammatory paradigm that has led to key discoveries in innate immunity. The transparent zebrafish (Danio rerio) larva is highly amenable to in vivo microscopy and has emerged as a valuable model for the study of host defence against bacterial infection. In this thesis, I use the zebrafish to explore the innate immune response to Shigella infection, and illuminate new ways to control bacterial infection in vivo. Septins are an evolutionarily conserved family of cytoskeletal proteins with diverse biological functions. Very recent work has shown a key role for components of the cytoskeleton in inflammation control, yet a role for septins was unknown. In Chapter 3, I develop a zebrafish hindbrain model of Shigella infection and reveal a new role for septins in the restriction of inflammation crucial for host defence. The global rise in antibiotic resistance amongst human pathogens has prompted an urgent search for novel antimicrobials. Bdellovibrio bacteriovorus are predatory bacteria that invade and kill Gram-negative species. Bacterial predation has been studied extensively in vitro but little is known of its efficacy in vivo. In Chapter 4, I use the Shigella-zebrafish infection model developed in Chapter 3 to show how immune cells and Bdellovibrio can work together to cure infection from multidrug resistant Shigella. Septins were discovered for their essential roles in cell division. S. flexneri is controlled by neutrophils in vivo, and emergency granulopoiesis is a haematopoietic program of neutrophil production used to counteract immune cell exhaustion during infection. In Chapter 5, I use Shigella infection of zebrafish to reveal a cell autonomous role for septins in haematopoietic stem cell-driven emergency granulopoiesis and in enhancing host immunity. Overall, the findings in this thesis have important implications for the treatment of inflammatory, infectious and haematological disease. As a result of these data, manipulation of the septin cytoskeleton represents a novel strategy by which to control inflammation. Furthermore, results obtained using Bdellovibrio are promising for the future consideration of living therapies to treat bacterial infection. Finally, the host cell division machinery can be used to modulate the haematopoietic response to infection and boost host defence. Collectively, results obtained using our Shigella-zebrafish infection model are highly translatable to higher vertebrates, including humans.

Optical spectroscopy of a brown dwarf candidate

description: We have used the Low-Resolution Imaging Spectrograph on the Keck II telescope to observe the brown dwarf candidate D04 (Hawkins et al, 1998). The spectrum matches that of a spectral-type M7 dwarf, implying a photospheric temperature of $\approx 2600$K. This is consistent with the available (R-I)$_C$ and (I-K) colours. If the parallax measured by Hawkins et al is correct, then the implication is that D04 has a radius of $\sim 0.035 R_\odot$, or one-third that of Jupiter. This contradicts the predictions made by current stellar models that electron degeneracy leads to nearly constant radii for stars and brown dwarfs at masses below 0.1 M$_\odot$. We suggest that an equally valid interpretation of the data is that D04 is a VB8 analogue at a distance of $\approx 150$ parsecs.

description: Skeletal muscle regeneration after serious injury highly relies on local stem cell proliferation and differentiation which are processes that are tightly regulated by macrophages. Utilization of tissue-derived and ex-vivo expanded mesenchymal stromal cells (MSCs) in skeletal muscle regeneration has been heavily researched for the past decades but the results have not been consistent and the potential therapeutic mechanism or mechanisms remains unclear. In this project, we characterized the cell components of MSCs after inducing cell death under different conditions and confirmed their anti-inflammatory and pro-regenerative effects on macrophage polarization in vitro. We further investigated the underlying mechanisms of macrophage polarization by different components resulting from cell death. We found potent therapeutic effects from freeze and thaw (F&T) induced cell debris, and these effects are dependent on the externalization of phosphatidylserine (PtS) on the plasma membrane. In contrast, effects from the supernatant of F&T induced cell death primarily depends on the released protein content. Based on the findings from our in vitro studies, we applied the F&T induced cell supernatant to an animal model of peripheral artery disease (PAD) to treat muscle injury caused by a severe ischemia. This treatment resulted in significantly improved muscle functional and histological recovery as well as increased blood flow to the affected muscles 2 weeks after the injury procedure, validating the therapeutic potential of cell components of MSCs induced by F&T process, obviating the need for a viable cell population to treat injury. This result has implications for cell-free therapeutic approaches for ischemic injury to muscle.
Structural integrity of additive manufactured cellular lattice structures

description: Additive manufacturing (AM) is a digital manufacturing process used to fabricate component geometries by the successive addition of material to a substrate, in contradiction to the successive removal of material as is the case with conventional machining operations. Advantages of using AM are efficient material consumption, minimal need for purpose-built tooling, relatively high portability facilitating on-site manufacturing, and unprecedented design freedom with the capability to reproduce very complex features. An application exploiting the design freedom offered by AM is the concept of cellular lattice structures, allowing for the implementation of very effective weight optimisation and low material usage into component design. The mechanical properties of cellular lattice structures can be tailored to fit the application simply by the manipulation of the cell geometry. The laser based powder bed fusion (LPBF) AM process, consuming 316L stainless steel powder, was used during this study to build and test material samples to investigate the influence of the build process parameters on the processed material properties. The parameter settings necessary to produce the best performing material samples were identified and used to model and predict the behaviour of cellular lattice structures built using the same process. An analytical model was developed in parallel to compute the elastic response and the relative density of lattice structures with specified dimensional cell parameters. The suitability of the STL file format, the most commonly used format to communicate geometry data to AM machines, to carry and process lattice structure geometry data was assessed and improvements were suggested to overcome some of the identified limitations. Finally, the acoustic resonance (AR) characterisation method was applied to measure the elastic response of AM lattice structure samples, with comparison to quasi-static compression characterisation and finite element (FE) modelling to evaluate the suitability of AR to characterise lattice structures. AR testing exhibited sensitivity to loose powder adhesion, an anomalous phenomenon where additional material fuses to the manufactured component surface during the AM build process. This limits the use of AR testing alone quantitatively while supplying a qualitative metric for assessing the quality of an AM build. A modification to the standard AR method was suggested which allows the extraction of multiple elastic stiffness measurements from a single test by utilising the detected overtone frequencies as well as the fundamental.

description: Sarin explosive dispersion simulations indicate that the effects of military, terrorist and accidental explosions on Sarin storage areas could be devastating at large distances from ground zero as they would practically amount to gigantic lethal chemical weapon explosions. As a case study, the April 14, 2018 military strikes on the alleged Syrian chemical weapons sites are investigated due to their high relevance and similarity to the Sarin releases occurred in the US demolition operations at the Khamisiyah Pit in Iraq (1991) believed to have been a possible source of the Gulf War Syndrome. The results show that even if a few kilograms of Sarin had been explosively released from the alleged chemical weapons sites targeted in Syria then hundreds to thousands of people would have experienced lethal or serious irreversible health effects in Syria. The prospect of the appearance of a Sarin-induced Syrian War Syndrome is also discussed for the first time.
description: After the publication of the first version of the paper its author detected and corrected errors in the library of EPICODE which were acknowledged by the creators of the code at LLNL. Unfortunately, those errors had affected some of the calculations of the first version and therefore its revision was deemed necessary.

description: We have used both the Low-Resolution Imaging Spectrograph and the HIRES echelle spectrograph on the Keck telescopes to obtain spectra of twelve candidate members of the Hyades cluster identified by Leggett and Hawkins (1988, 1989). All of the objects are chromospherically-active, late-type M-dwarfs, with H$α$ equivalent widths varying from 1 to 30Å. Based on our measured radial velocities, the level of stellar activity and other spectroscopic features, only one of the twelve stars has properties consistent with cluster membership. We consider how this result affects estimates of the luminosity and mass function of the Hyades cluster. Five of the eleven field stars have weak K I 7665/7699Åand CaH absorption as compared with M-dwarf standards of the same spectral type, suggesting a lower surface gravity. Two of these sources, LH0416+14 and LH0419+15, exhibit significant lithium 6708 Åabsorption. Based partly on parallax measurements by the US Naval Observatory (Harris et al, 1998), we identify all five as likely to be young, pre-main sequence objects in or near the Taurus-Auriga association at distances of between 150 and 250 parsecs. A comparison with theoretical models of pre-main sequence stars indicates masses of less than 0.05 M$_\odot$.

description: Microwave photonics (MWP) provides wideband, programmable, and low-loss platforms for analog signal processing with high power handling and immunity to electromagnetic interference. Recent advancements in integrated photonics have enabled a variety of on-chip functions for signal processing including true-time delays, tunable switches, high-Q resonators, frequency combs, and so on which make MWP a promising solution for ever-increasing demand of high throughput signal processing. However, achieving the desired dynamic range (DR) from MWP links has remained elusive for signal processing applications. The nonlinear sources of MWP links are studied with a focus on integrated MWP for signal processing. The concept of interference induced distortions (IIDs) are introduced which are generated by passive structures in the link. As demonstrated by the presented theory, simulations, and measurement results, IIDs from passive components can dominate the nonlinear distortions of active components in the link by tens of dB. The impact of parasitic interferometric structures which are formed by design, fabrication, and packaging imperfections on IIDs are discussed along with mitigation solutions. The impact of frequency chirp in active devices on IIDs are studied by simulation and measurement results which shows a magnified sensitivity of IIDs to parasitic interferences when chirp increases. On-chip tap combination, however, is a desired interference in many applications which its implementation remains challenging due to instabilities and limited DR originating from IIDs. Incoherent combiners are proposed in the literature based on multiple PDs or wavelengths at the cost of limiting bandwidth, increasing insertion loss, and necessitating a frequency comb. A tapered-pitch array combiner (TPAC) is introduced here to break the trade-offs in the incoherent and off-chip solutions. TPAC is designed based on the rules derived from the theory and simulation presented for modeling IIDs. A SFDR₃ equal to 107.3 dBc.Hz [superscript 2/3] is measured for the fabricated TPAC combing taps of a 6-tap filter using one wavelength and one PD. A modified TPAC is proposed for further IID suppression using optical phase alignment (OPA) of taps where up to than 26.9 dB IMD₃ suppression is measured. Finally, the stability and tunability of OPA approach are discussed followed by suggestions for future research.

description: We present optical data gathered by the VLT Test Camera in the V-band at the radio (interferometric) position of PSR1706-44. We find no optical counterpart to the pulsar in the VLT image. At a distance of 2.7 arcsec from a nearby bright star, the 3-sigma upper limit to the pulsar magnitude above the background is V = 25.5. Within an error circle of 1.0 arcsec the upper limit is degraded in the direction towards the star. At a distance < 2 arcsec from the star we can with confidence only claim an upper limit of V = 24.5. This is still several magnitudes fainter than previous estimates. The implications of the optical upper limit taken together with the high energy pulsed gamma-ray radiation for theoretical models of pulsar emission are discussed.

Development of a computational-experimental model to predict glioma response to radiation treatment

description: Radiation is essential to malignant glioma and glioblastoma treatment. However, the prognosis of glioblastoma remains poor with a median survival of 15 months. This is partly due to the heterogeneous radiosensitivity among patients. If we have a mechanism-based model that can make dynamic predictions, it has the potential to guide and optimize the treatment on a patient-specific basis. The purpose of this dissertation is to develop and validate a computational-experimental model that explicitly incorporates underlying radiobiology as well as making accurate predictions of the radiation response of glioma cells. Specifically, we first propose a mathematical model to a single dose of radiation that incorporates DNA repair and cell death pathways and validate it under eight different doses from 2 Gy to 16 Gy via microscopy in vitro. We then extend this model to fractionated treatment and validate it with six different fractionation schemes using total doses of either 16 Gy or 20 Gy. Finally, we propose a data assimilation framework that will individualize the prediction based on the observations of individual replicates, which further improves the prediction accuracy. We present a full story of how developing a mechanism-based experiment-driven mathematical model can assist us in characterizing and predicting radiation response, which could eventually, be used to optimize the treatment schedule.
