description: A set of new exact analytical General Relativity (GR) solutions with time-dependent and spatially inhomogeneous quintessence demonstrate 1) a static non-empty space-time with a horizon-type singular surface; 2) time-dependent spatially homogeneous `spheres' which are completely different in geometry from the Friedmann isotropic models; 3) infinitely strong anti-gravity at a `true' singularity where the density is infinitely large. It is also found that 4) the GR solutions allow for an extreme `density-free' form of energy that can generate regular space-time geometries.

description: Conformations of a single semiflexible polymer chain dissolved in a low molecular weight liquid crystalline solvents (nematogens) are examined by using a mean field theory. We takes into account a stiffness and partial orientational ordering of the polymer. As a result of an anisotropic coupling between the polymer and nematogen, we predict a discontinuous (or continuous) phase transition from a condensed-rodlike conformation to a swollen-one of the polymer chain, depending on the stiffness of the polymer. We also discuss the effects of the nematic interaction between polymer segments.

description: Brahmaputra river basin is one of the most vulnerable areas in the world subject to combined effects of glacier melt, extreme monsoon rainfall and sea level rise. Water is emerging as a new possible irritant between China and India. For India, Water of Brahmaputra constitutes a major lifeline for people of Tibet and North Eastern states. The building of dams and diversion projects in Tibet by China is a matter of grave concern for lower riparian states. For China, it is having hidden inclination to create employment potentials for more than millions of people by making Brahmaputra diversion project forward. The requirement of fresh water as the pollution grows and population rise has forced China to have the Tsangpo-Brahmaputra River project. The objective of this paper is to focus the reaction of both people on the water diversion issue, disastrous ecological consequences and the urgent necessity for having a water treaty between Asian giants. It also examines the hegemonic tendencies of China on Brahmaputra River & exercise of power for economic gains and outcomes. The policies China takes on trans- Boundary Rivers are not symptom of peaceful nature of its rise. In addition, it establishes the fact that sharing of information, ecosystem-friendly policies, thought and mutual understanding will dispel the suspicion and develop trust between two countries, creating an enabling environment for better management of Brahmaputra River.

description: Federally subsidized crop insurance has expanded in recent decades, with annual premium subsidies increasing from roughly $1 to $7 billion dollars between 2000 and 2013. The 2014 Farm Act further expanded crop insurance, making it the main conduit of financial support to farmers. Although designed for non-environmental goals, subsidized insurance may affect the use of land, fertilizer, and agrochemicals and therefore environmental externalities from agriculture such as nutrient and chemical runoff into lakes and streams. We use a newly constructed farm-level panel data set to examine farmer responses to changes in insurance coverage. Identification comes from an instrumental variable approach that exploits program limits on coverage, which constrained the response of some farmers to increasingly generous subsidies more than others. Our estimates indicate that expanded coverage had a small, if any, effect on farm decisions such as fertilizer and chemical use.

description: This thesis presents work on a series of devices for the generation of photonic quantum states based on self-assembled InAs quantum dots, which are among the most technologically mature candidates for practical quantum photonic applications due to their high internal quantum efficiency, narrow linewidth, tunability and straightforward integration with photonic and electric components. The primary results presented concern sources of multi-photon entangled states and single-photon sources with high repetition rate, both of which are crucial components for emerging photonic quantum technologies. First, we propose a scheme for the sequential generation of entangled photon chains by resonant scattering of a laser field on a single charged particle in a cavity-enhanced quantum dot. The charge has an associated spin that can determine the time bin of a photon, allowing for information encoding in this degree of freedom. We demonstrate coherent operations on this spin and realize a proof-of-principle experiment of the proposed scheme by showing that the time bin of a single-photon is dependent on the measured state of the trapped spin. The second main avenue of work investigates the effects of a surface acoustic wave, a mechanical displacement wave confined to the surface of a substrate, on the optical properties of quantum dots. In particular, we exploit the dynamic acoustically-induced tuning of the emission energy to modulate the Purcell effect in a pillar microcavity. Under resonant optical excitation we demonstrate the conversion of the continuous wave laser into a pulsed single-photon stream inheriting the acoustic frequency of 1 GHz as the repetition rate. High resolution spectroscopy reveals the presence of narrow sidebands in the emission spectrum, whose relative intensity can be controlled by the acoustic power and laser detuning. Furthermore, we develop a platform for analogous in-plane experiments by transferring GaAs membranes hosting quantum dots onto LiNbO3 substrates and patterning them into whispering gallery mode optical resonators. In addition to Purcell enhancement and acoustic tuning of the emission, the devices exhibit strong localized mechanical resonances. Finally, we perform initial experiments on the effects of a surface acoustic wave on the spin of a charge trapped in a quantum dot. We integrate acoustic transducers with charge-tunable diodes, where the charge state of the dot can be precisely controlled by an applied bias voltage, and demonstrate the frustration of optical spin pumping by the acoustic wave.

description: In this work, we have formulated and implemented a mixed unstructured mesh-based finite element (FE)-Fourier decomposition scheme for gyrokinetic simulations in realistic tokamak geometry. An efficient particle positioning (particle-triangle mapping) scheme for the charge deposition and field scattering using an intermediate grid as the search index for triangles has been implemented and a significant speed-up by a factor of $\sim30$ is observed as compared with the brute force scheme for a medium-size simulation. The TRIMEG (TRIangular MEsh based Gyrokinetic) code has been developed. As an application, the ion temperature gradient (ITG) mode is simulated using the simplified gyrokinetic Vlasov-Poisson model. Our simulation and that using the ORB5 code for the DIII-D Cyclone case show reasonable agreement. As an additional application, ITG simulations using an ASDEX Upgrade equilibrium have been performed with density and temperature gradient profiles similar to the Cyclone case. Capabilities of the TRIMEG code for simulations with realistic experimental equilibria in the plasma core and in the whole plasma volume with open field lines are demonstrated.

description: Objective: This study seeks to determine compression (Cmax) and compression-related injury variables (velocity and viscous injury criterion: Vmax and VCmax) from chestband data in pure lateral and oblique far-side impact sled tests. Methods: The 3-point belt–restrained mid-sized male Test Device for Human Occupant Restraint (THOR) dummy was placed on a buck and subjected to side impacts with and without center-mounted airbags. The change in velocity was 8.3 m/s for all conditions. Two chestbands were routed around the outer circumference of the THOR at the levels of the third and sixth ribs. Maximum chest deflections were computed using strain gauge signals from the chestbands and their temporal contours. Three methods were used to determine deflection metrics. The first method paralleled methods used in previously published human cadaver studies; the second method used the actual anchor point location and actual alignment of the dummy’s internal sensors; and the third method used the anchor location of the internal sensor but determined the sensor’s locations on the contour confining to the aspect of the sensor. These 3 approaches are abbreviated as the SD, ID, and TD variables. The injury variables Cmax, Vmax, and VCmax were determined according to accepted procedures. Their peak magnitudes were extracted and an evaluation of their accuracy was made based on the SD method. Results: The average SD-based Cmax magnitudes for the upper and lower chest levels were 0.12 and 0.17 m/s, the Vmax magnitudes were 5.3 and 1.8 m/s, and the VCmax magnitudes were 0.24 and 0.15 m/s, respectively. Other data are given for all variables at the 2 levels of the thorax in the body of this paper. The ID-based peak variables were the lowest, and this observation was true regardless of the aspect, right or left side. In contrast, the SD method produced the greatest magnitudes of the variables. The VCmax variable had the greatest normalized difference among all 3 injury variables. Conclusions: Though the present study is limited in scope, the predetermined placement of the internal sensors in the THOR dummy underpredicted chest deflection-related injury variables, and the viscous criterion was the least reliable variable in these lateral and oblique far-side impact sled tests.
Non-radial instabilities of isothermal Bondi accretion with a shock: vortical-acoustic cycle vs post-shock acceleration
Creators: name: Foglizzo, T.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The linear stability of isothermal Bondi accretion with a shock is studied analytically in the asymptotic limit of high incident Mach number M_1. The flow is unstable with respect to radial perturbations as expected by Nakayama (1993), due to post-shock acceleration. Its growth time scales like the advection time from the shock r_sh to the sonic point r_son. The growth rate of non-radial perturbations l=1 is higher by a factor M_1^{2/3}, and is therefore intermediate between the advection and acoustic frequencies. Besides these instabilities based on post-shock acceleration, our study revealed another generic mechanism based on the cycle of acoustic and vortical perturbations between the shock and the sonic radius, independently of the sign of post-shock acceleration. The vortical-acoustic instability is fundamentally non-radial. It is fed by the efficient excitation of vorticity waves by the isothermal shock perturbed by acoustic waves. The growth rate exceeds the advection rate by a factor log M_1. Unstable modes cover a wide range of frequencies from the fundamental acoustic frequency ~c/r_sh up to a cut-off ~c/r_son associated with the sonic radius. The highest growth rate is reached for l=1 modes near the cut-off. The additional cycle of acoustic waves between the shock and the sonic radius is responsible for variations of the growth rate by a factor up to 3 depending on its phase relative to the vortical-acoustic cycle. The instability also exists, with a similar growth rate, below the fundamental acoustic frequency down to the advection frequency, as vorticity waves are efficiently coupled to the region of pseudosound. These results open new perspectives to address the stability of shocked accretion flows.

description: All organelles of eukaryotic cells form an intricate network of membrane contact sites (MCS) and thereby promote cellular functions such as lipid metabolism, signalling and organelle biogenesis. The formation of cortical endoplasmic reticulum (cER) - plasma membrane (PM) contacts in budding yeast cells is mediated by a set of six conserved proteins. By combining correlative light and electron microscopy (CLEM) and electron cryo-tomography (cryo-ET) with yeast genetic techniques, this work addresses unanswered questions about the cellular architecture of ER-PM contacts and how protein organisation in uences their functionality. CLEM on resin-embedded cells shows that protein composition at MCS modulates the cER membrane curvature rather than the membrane distance to the PM. Speci cally, the tricalbins (Tcbs), the yeast orthologs of Extended-Synaptotagmins, localise to cortical ER of high membrane curvature. A high-throughput genetic screen uncovers a new role for Tcbs in the maintenance of PM bilayer lipid asymmetry and redundancies in lipid routes through other cellular MCS, such as nucleus-vacuole junctions and ER-mitochondria contacts. In order to visualise protein organisation in cells at the highest level of preservation, cryo-ET acquisition and image analysis methods for this study were rst established on BAR domain- containing proteins at the PM. These methods, in combination with cryo-focussed ion beam milling, were subsequently used to visualise ER-PM contact site protein organisation in situ. The tricalbins are lipid transfer proteins integral to the ER, which contact the PM via C2 domains, potentially in a calcium dependent manner. The cryo-ET data shows an increase in protein layer bound to the PM at high cellular calcium, compatible with increased C2 binding to the PM. Cryo-ET of cells induced for expression of tricalbin-3, but devoid of all other ER-PM-forming proteins, reveals protein densities bridging the ER and PM. The range of structures observed strongly favours a model in which the lipid transfer domain functions as shuttle between the two contact site membranes in vertical orientation.

description: The unique structural features and suitability of the SiO2 micro particles in different application areas have mobilized a worldwide interest in the last few decades. In this report a classical method known as the Stober method has been used to synthesize silica micro spheres. These microparticles have been synthesized by the reaction of tetraethyl orthosilicate (Si(OC2H5)4, TEOS) (silica precursor) with water in an alcoholic medium (e.g. ethanol) in the presence of KCl electrolyte and ammonia as a catalyst. It has been observed that the size of the microparticles closely depends on the amount of the TEOS and ammonia. A decrease in the size of micro particles from 2.1 micrometer to 1.7 micrometer has been confirmed as the amount of TEOS increases from 3.5 ml to 6.4 ml respectively. In similar way a decrease in the diameter of the micro particles from 2.1 micrometer to 1.7 micrometer has been observed with increase in the ammonia content from 3 ml to 9 ml.

The projective to Einstein correspondence and a kink on a wormhole

description: The first part of this thesis is concerned with $\phi^4$ field theory on a wormhole spacetime in 3 + 1 dimensions. This spacetime has two asymptotically flat ends connected by a spherical throat of radius $a$. We show that the theory possesses a kink solution which is linearly stable, and compare its discrete spectrum to that of the $\phi^4$ kink on $\mathbb{R}^{1,1}$. We present some results on the non–linear resonant coupling between the discrete and continuous spectra in the range of a where there is exactly one discrete mode. The second part of the thesis is based on recent work by Dunajski and Mettler. They show that a class of neutral signature Einstein manifolds $M$ can be canonically constructed as rank $n$ affine bundles over projective structures in dimension $n$. These have the same symmetry group as the underlying projective manifold, and are also endowed with a natural symplectic form, which is related to the metric by an endo-morphism of the tangent bundle that squares to the identity. Consequently, they carry an almost para–Kähler structure. We show that every metric within the class is a Kaluza–Klein reduction of an Einstein metric on an $\mathbb{R}^∗$ bundle over M. We also show that the structures are para–c–projectively compact in the sense of Čap–Gover, and interpret the compactification in terms of the tractor bundle of the projective structure. In dimension four, the manifolds $M$ have anti–self–dual conformal curvature, and are thus associated with a twistor space. In the presence of a symmetry, they can be reduced to Einstein-Weyl structures in dimension three via the Jones–Tod correspondence. Because $M$ is also Einstein with non–zero scalar curvature, these Einstein–Weyl structures are determined by solutions of the SU($\infty$)–Toda equation. We investigate the Einstein–Weyl structures which can be obtained in this way in terms of the symmetry group of the underlying projective surface. Several examples are considered in detail, resulting in new, explicit solutions of the SU($\infty$)–Toda equation. We focus in particular on the case where the projective structure is $\mathbb{RP}^n$, additionally describing the Jones–Tod reduction from the twistor perspective.

description: One of the most widespread methods to determine if a quantum state is entangled, or to quantify its entanglement dimensionality, is by measuring its fidelity with respect to a pure state. In this Letter we find a large class of states whose entanglement cannot be detected in this manner; we call them unfaithful. We find that unfaithful states are ubiquitous in information theory. For small dimensions, we check numerically that most bipartite states are both entangled and unfaithful. Similarly, numerical searches in low dimensions show that most pure entangled states remain entangled but become unfaithful when a certain amount of white noise is added. We also find that faithfulness can be self-activated, i.e., there exist instances of unfaithful states whose tensor powers are faithful. To explore how the fidelity approach limits the quantification of entanglement dimensionality, we generalize the notion of an unfaithful state to that of a D-unfaithful state, one that cannot be certified as D-dimensionally entangled by measuring its fidelity with respect to a pure state. For describing such states, we additionally introduce a hierarchy of semidefinite programming relaxations that fully characterizes the set of states of Schmidt rank at most D.

description: Based on a previous study of deriving the chiral Lagrangian (CL) from QCD, we illustrate the main feature of QCD predictions for the CL coefficients (CLC) in certain approximations. We first show that, in the large-N(c) limit, the anomaly part contributions to the CLC are exactly cancelled by certain terms in the normal part contributions (NPC), so that the final results only concern the remaining NPC depending on QCD interactions. We then do the calculation in a simple approach with further approximations. The obtained CLC and quark condensate are consistent with the experiments.

description: We consider a general central-field system in D dimensions and show that the division of the kinetic energy into radial and angular parts proceeds differently in the wavefunction picture and the Weyl-Wigner phase-space picture. Thus, the radial and angular kinetic energies are different quantities in the two pictures, containing different physical information, but the relation between them is well defined. We discuss this relation and illustrate its nature by examples referring to a free particle and to a ground-state hydrogen atom.

description: The gravitational wave (GW) background produced at the cosmological chiral phase transition in a conformal extension of the standard model is studied. To obtain the bounce solution of coupled field equations we implement an iterative method. We find that the corresponding $O(3)$ symmetric Euclidean action $S_3$ divided by the temperature $T$ has a simple behavior near the critical temperature $T_C$: $S_3/T \propto (1-T/T_C)^{-γ}$, which is subsequently used to determine the transition's inverse duration $β$ normalized to the Hubble parameter $H$. It turns out that $β/H \gtrsim 10^3$, implying that the sound wave period $τ_\text{sw}$ as an active GW source, too, can be much shorter than the Hubble time. We therefore compute $τ_\text{sw} H$ and use it as the reduction factor for the sound wave contribution. The signal-to-noise ratio (SNR) for Deci-Hertz Interferometer Gravitational Wave Observatory (DECIGO) and Big Bang Observer (BBO) is evaluated, with the result: SNR$^\text{DECIGO} \lesssim 1.2$ and SNR$^\text{BBO} \lesssim 12.0$ for five years observation, from which we conclude that the GW signal predicted by the model in the optimistic case could be detected at BBO.

description: This thesis focuses on the execution of King Charles I of England on 30 January 1648/9. It seeks to investigate and document the impact of the event on the English, specifically its effect on contemporary senses of time. Charles was a king put on trial and executed by members of his own Parliament. Organised by radical supporters of the Army who had taken over the government in a coup, his execution shook the nation to its core. The king was God’s lieutenant on earth, and he was the font of all law and justice. His execution sparked a wave of mourning and commemoration, as well as a sense of loss and psychic disorganization. His death left the country at a crossroads, unsure of how to proceed. What sort of time were they living in, and what did the future hold? Were there discernible shapes and patterns of time? Were these altered by an event as unprecedented as the regicide? I focus on three groups of writers: astrologers, history writers, and newsbook authors, performing a diachronic analysis of their publications to understand how their ideas of time and the future evolved in the tumultuous time of civil war and regicide. Through a close examination of sources like almanacs, newsbooks, and polemical histories, I conclude that the early moderns tried to normalise the disruptive regicide by embedding it within larger narratives of time. They downplayed the radical nature of the event in search of order, incorporating it within grand narratives of God’s providential plans on earth, of generational changes in society and politics, or of recurring cycles of rebellious behaviour. The regicide gave contemporaries an opportunity to create, clarify, and strengthen their grand narratives and schemes of time.

description: Billions of dollars flow into low-income countries each year to help alleviate poverty. Assessing the effectiveness of these dollars is necessary to measure program success and to allocate such funds among competing projects. This study measures the impact of the first phase of the Cocoa Livelihood Program (CLPI), a current World Cocoa Foundation project sponsored by the Bill and Melinda Gates Foundation. The project seeks to improve the livelihood of over 200,000 small cocoa producers in Sub-Saharan Africa via training, crop diversification and farmer based organizations. Using data collected from 2,048 pre and post CLPI interviews of cocoa producers in Ghana, Cote D’ivoire, Nigeria and Cameroon, the economic impact of the CLPI program can be estimated. The results show that yield enhancements attributable to CLPI are 36%, 38%, 49% and 24% in Ghana, Côte D’Ivoire, Nigeria and Cameroon, respectively. Using a total program cost of $158-$200 per beneficiary and estimated annual benefits of $86-$152 per beneficiary over 25 years, the benefit- cost ratios were estimated to range from $13 to $22 for every dollar spent on human capital development.

description: Dark Matter can form bound states upon the emission of quanta of energy equal to the binding energy. The rate of this process is large for strongly-interacting Dark Matter, and further enhanced by long distance effects. The resulting monochromatic and diffuse $γ$-rays can be tested in indirect detection experiments. If Dark Matter has electroweak charge, indirect signals include multiple observable photon lines for masses in the TeV range. Else if it couples only via a dark photon portal, diffuse spectra from dwarf galaxies and CMB reionization set powerful limits for masses below a TeV. This mechanism provides a powerful means of probing Asymmetric Dark Matter today.

description: We propose to use relative galaxy ages as a means of constraining cosmological parameters. By measuring the age difference between two ensembles of old galaxies at somewhat different redshifts, one could determine the derivative of redshift with respect to cosmic time, dz/dt. At high redshifts, z=1-2, this measurement would constrain the equation-of-state of the dark energy, while at low redshifts, z< 0.2, it would determine the Hubble constant, H_0. The selected galaxies need to be passively-evolving on a time much longer than their age difference.

description: Objective: The objective of this study was to understand the characteristics and underlying contributing factors in crashes between motorized 2-wheelers (M2Ws) and pedestrians in India. Methods: For the purpose of this study, data from the Road Accident Sampling System–India (RASSI) collected from April 1, 2011, to March 31, 2018, were analyzed. A sample of 97 crashes between M2Ws and pedestrians was studied to understand their characteristics and contributing factors. Results: Seventy percent of the crashes occurred while pedestrians were crossing the road. Seventy-five percent of M2W riders and 47% of pedestrians with age indicated were in the age group 21–50. Seventy-eight percent of M2W riders were not wearing helmets. Maximum Abbreviated Injury Scale (MAIS) 3+ injuries were sustained by 55% of pedestrians and 32% of M2W riders. Poor pedestrian infrastructure or a lack thereof influenced the occurrence of 63% of crashes. Conclusions: This study shows that M2Ws pose a considerable risk to pedestrians in terms of causing fatal and serious injuries in such inter–vulnerable road user (VRU) crashes. Though helmet enforcement could aid in mitigating injuries among M2W riders, proper infrastructure planning would benefit both. Further study is warranted to explore other dimensions of inter-VRU crashes.

description: We study a quantum model of dynamical Casimir effect in an optical cavity enclosed by a freely moving mirror attached to a harmonic spring. The quantum fluctuations of the friction force exerted by the dynamical Casimir emission onto the moving mirror are investigated, as well as their consequences on the quantum state of the mirror oscillation. Observable signatures of the interplay of the nonlinear nature of the effective mirror-cavity coupling and of the discreteness of the emitted photons are pointed out, in particular as a fast diffusion of the mirror oscillation phase. These results are interpreted in the language of quantum field theories on curved space-times as a breakdown of the standard semiclassical theory of the backreaction.

description: Inspired by their use in nature, non-covalent interactions have recently started being used in small molecule catalysis for control of selectivity. To date, this has been particularly fruitful in the area of enantioselective catalysis when using ion pairing or hydrogen bonding. Despite the success seen by ion pairing in enantioselective organocatalysis, this interaction has rarely been used for other types of selectivity, such as positional selectivity. This thesis explores the possibility of implementing ion pairing in transition metal catalysis for control of regioselectivity. Specifically, ion pairing was investigated for achieving meta and para selectivity in iridium catalysed C–H borylation. An ion pairing interaction between a functionalised ligand and matching functionality on a substrate was initially explored for achieving meta C–H selectivity. By using an anionic sulfonate group on the ligand and cationic quaternary ammonium salt substrates, good to excellent meta selectivity was obtained with four classes of substrates, with various tether lengths between the arene and the ammonium functionality. Further functionalisation of the products was demonstrated and a similar strategy was attempted on protonated pyridines as cationic substrates, with limited success. Para selectivity was next achieved by using ion pairing in a different context; sulfonate salt substrates were ion paired with bulky tetrabutylammonium counterions, which were proposed to sterically disfavour borylation at the meta position, leading to selective para borylation. Remarkably, this selectivity was obtained with standard bipyridine ligands. Six classes of substrates were amenable to this methodology: derivatives of aniline and benzylamines, phenol and benzylalcohols, as well as benzenesulfonate and benzylsulfonate salts. Following borylation, the sulfamate and sulfate salts were deprotected to reveal the parent free aniline, benzylamine, phenol or benzylalcohol, borylated at the para position. Overall this work shows that ion pairing is a viable interaction for control of positional selectivity, and two different operating modes have been demonstrated. It is hoped that the findings presented herein will encourage further exploration of this interaction for control of positional selectivity in catalysis.

description: The technological innovations over the past decades have extensively enhanced the existing methods of diagnosis while also allowing for newer systems to be implemented in a clinical setting. One of those advancements that is underutilized clinically is Digital infrared thermal imaging. It can be used to detect illnesses where skin temperature can reflect the presence of inflammation in underlying tissues or where blood flow fluctuates due to a clinical abnormality such as arthritis and repetitive strain injury. In this article, the researcher proposes a compact, handheld device that combines the aforementioned imaging technology with a photoelectric sensor and a Stereophotogrammetry based imaging system to create a digital 3D thermal reconstruction of a patient or a part of a patient’s body while being financially viable to be mass manufactured. The device could then be used to diagnose certain conditions, create a visual medical profile to monitor the patient’s progress or aid in the discovery of new modalities for early detection.

description: Drug safety is a major cause of attrition in contemporary drug development. Many promising candidate drugs are terminated in the developmental process or withdrawn in the post-approval stage because of adverse drug reactions (ADRs). Among these, cardiovascular (CV) ADRs occur with a high incidence. Affecting the heart, blood vessels and blood components, CV ADRs can lead to hypertension, heart failure, cardiac arrhythmias and thrombosis. The prompt identification of CV toxicity would reduce both the delay and cost of drug development and increase patient safety. Drug-induced vascular injury (DIVI) in pre-clinical toxicology studies involves damage to endothelial (EC) and smooth muscle cells (SMC) in small and medium sized vessels, but little is known about the mechanisms of DIVI. Damage includes microhaemorrhage, endothelial junction disruption, SMC necrosis and inflammation. DIVI is often observed preclinically, driving a need to study this in human tissue. The aim of this thesis was to develop and characterise an in vitro human model that would allow the study of DIVI in human tissue during drug development. The first stage was to effectively reproduce DIVI in an animal model. To reduce the utilisation of live animals, a vessel explant was used. To determine whether DIVI was recapitulated ex vivo von Willebrand factor (VWF) release, one of the hallmarks of DIVI, was analysed using four drugs reported in the literature to produce DIVI. The same four drugs were then tested in human EC and SMC for the following features of DIVI: (1) VWF release; (2) EC monolayer disruption; (3) inflammation; (4) EC and SMC death. Both ex vivo in rats and in vitro in humans, the drugs did not exhibit common characteristics and each expressed DIVI features in different ways. The human in vitro model was also assessed in a co-culture of EC and SMC, and in the presence of a flow-mimetic that reproduces in vivo-derived hemodynamics. It was concluded that DIVI cannot be fully recapitulated in vitro in such a reductionist cellular model, suggesting that exposure to the complex microenvironment of the vasculature may be required for the lesions to develop, or that DIVI may, in fact, not be relevant to humans at all.
