Investigating transport phenomena in amorphous thin films using the Quartz Crystal Microbalance
Creators: name: Isbell, Mark-Antonin
Publisher: name: Imperial College London
Year: 2019

description: An increasing proportion of drug candidates in the pharmaceutical pipeline have significant aqueous solubility issues. Amorphous Solid Dispersions are a growing and innovative advancement to the field of drug formulation tackling this problem; however many issues remain unresolved, impacting their widespread adoption. The most notable issue is poor dissolution performance, attributed to the phase separation of the blend into drug-rich and polymer-rich phases on contact with water, called amorphous-amorphous phase separation (AAPS). This work is the first to study ASDs with the Quartz Crystal Microbalance (QCM). This work used the model compounds Ritonavir and Copovidone and performed gravimetric water sorption experiments. Thin films were cast, sub 300 nm, allowing for the better deconvolution of the water sorption and phase separation mechanisms. Furthermore, the QCM’s dissipation monitoring capability was able to detect the earliest signs of AAPS in films shown in the literature. The equilibrium water sorption kinetics were modelled using a Fickian based relaxation−diffusion model to highlight the impact of the inclusion of a hydrophobic drug in a hydrophilic carrier. All work on the QCM was corroborated with orthogonal techniques including the TEM-EDX, confocal microscopy, and AFM. The last was crucial in demonstrating that AAPS onset led to surface roughening and was related to the dissipation increase. It also showed further insights into the molecular mechanisms of AAPS growth mimicking that of spinodal decomposition. The work offered definitive proof that AAPS was a thermodynamic limited event and not a kinetic one, as sometimes debated in the literature; however, the amount of water plasticizing the ASD would determine the kinetics of AAPS growth. This miscibility drug loading limit was in line with results from literature dissolution performance data for the same ASD, reinforcing the impact of AAPS on dissolution. It was found that the inclusion of surfactants could improve the miscibility of the ASD but increase the speed of AAPS growth. This work also showed the importance of properly identifying and controlling the nanoconfinement effects due to the presence of interfacial regions in such thin amorphous films. This was done by comparing kinetic and equilibrium sorption uptake data based on thickness. This is also crucial in selecting the correct QCM model for measuring the actual mass uptake. The results show that maintaining miscibility is crucial to properly functioning ASD formulations. Furthermore, the work has shown that surfactants could be an ideal solution for resolving such issues. Finally, the QCM could be used for the rapid mass screening of ASDs for the appearance of AAPS when performing polymer-drug paired selections. This data could be valuable in the development of models for the rational pairing of both components.

description: We study the effect of the spin-orbit interaction on quantum gate operations based on the spin exchange coupling where the qubit is represented by the electron spin in a quantum dot or a similar nanostructure. Our main result is the exact cancellation of the spin-orbit effects in the sequence producing the quantum XOR gate for the ideal case where the pulse shapes of the exchange and spin-orbit interactions are identical. For the non-ideal case, the two pulse shapes can be made almost identical and the gate error is strongly suppressed by two small parameters, the spin-orbit constant and the deviation of the two pulse shapes. We show that the dipole-dipole interaction leads only to very small errors in the XOR gate.

description: Two dimensional SU(N) Yang-Mills theory is known to be equivalent to a string theory, as found by Gross in the large N limit, using the 1/N expansion. Later it was found that even a generalized YM theory leads to a string theory of the Gross type. In the standard YM theory case, Douglas and others found the string hamiltonian describing the propagation and the interactions of states made of strings winding on a cylindrical space-time. We address the problem of finding a similar hamiltonian for the generalized YM theory. As in the standard case we start by writing the theory as a theory of free fermions. Performing a bosonization, we express the hamiltonian in terms of the modes of a bosonic field, that are interpreted as in the standard case as creation and destruction operators for states of strings winding around the cylindrical space-time. The result is similar to the standard hamiltonian, but with new kinds of interaction vertices.

description: We evaluate, by means of variational calculations, the bound state energy E_B of a pair of charges located on the surface of a cylinder, interacting via Coulomb potential - e^2 / r . The trial wave function involves three variational parameters. E_B is obtained as a function of the reduced curvature C = a_0 / R, where a_0 is the Bohr radius and R is the radius of the cylinder. We find that the energetics of binding exhibits a monotonic trend as a function of C ; the known 1D and 2D limits of E_B are reproduced accurately by our calculation. E_B is relatively insensitive to curvature for small C . Its value is ~ 1% higher at C = 1 than at C = 0. This weak dependence is confirmed by a perturbation theory calculation. The high curvature regime approximates the 1D Coulomb model; within our variational approach, E_B has a logarithmic divergence as R approaches zero. The proposed variational method is applied to the case of donors in single-wall carbon nanotubes (SWCNTs).

Nonlinear Thermomagnetic Waves in Type II Superconductors
Creators: name: Taylanov, Nizam A.
Publisher: name: arXiv
Year: 2001
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: This work is devoted to analysis of the nonlinear dynamics of interrelated thermal and electromagnetic perturbations in a superconductor caused by dissipative effects involved in the viscous motion of the magnetic flux. The structure and evolution of the stationary thermomagnetic waves propagating in the superconductor is studied based on a system of nonlinear equations describing dynamics of the instability development in the system studied. The apperance of these structures is qualititively described and the wave propagation velocity is estimated. The affect a thermoactivated flux creep to the structures of the nonlinear thermomagnetic wave propagation is studied. It is shown that taking into account a nonlinear dependency of the current density $j$ on the electric field strength $E$ would not qualitatively change the main results, since the character of the equilibrium state on the phase plane remains esentially the same.

description: The well-known quasar SDSS J095253.83+011421.9 (J0952+0114) at z=3.02 has one of the most peculiar spectra discovered so far, showing the presence of narrow Ly$α$ and broad metal emission lines. Although recent studies have suggested that a Proximate Damped Ly$α$ system (PDLA) causes this peculiar spectrum, the origin of the gas associated with the PDLA is unknown. Here we report the results of MUSE observations that reveal a new giant ($\approx$ 100 physical kpc) Lyman $α$ nebula. The detailed analysis of the Ly$α$ velocity, velocity dispersion, and surface brightness profiles suggests that the J0952+0114 Ly$α$ nebula shares similar properties of other QSO nebulae previously detected with MUSE, implying that the PDLA in J0952+0144 is covering only a small fraction of the QSO emission solid angle. We also detected bright and spectrally narrow CIV$λ$1550 and HeII$λ$1640 extended emission around J0952+0114 with velocity centroids similar to the peak of the extended and central narrow Ly$α$ emission. The presence of a peculiarly bright, unresolved, and relatively broad HeII$λ$1640 emission in the central region at exactly the same PDLA redshift hints at the possibility that the PDLA originates in a clumpy outflow with a bulk velocity of about 500 km/s. The smaller velocity dispersion of the large scale Ly$α$ emission suggests that the high-speed outflow is confined to the central region. Lastly, the derived spatially resolved HeII/Ly$α$ and CIV/Ly$α$ maps show a positive gradient with the distance to the QSO hinting at a non-homogeneous ionization parameter distribution.

description: Thousands of transcriptome data sets are available, but approaches for their use in dynamic cell response modelling are few, especially for processes affected simultaneously by two orthogonal influencing variables. We approached this problem for neuroepithelial development of human pluripotent stem cells (differentiation variable), in the presence or absence of valproic acid (signaling variable). Using few basic assumptions (sequential differentiation states of cells; discrete on/off states for individual genes in these states), and time-resolved transcriptome data, a comprehensive model of spontaneous and perturbed gene expression dynamics was developed. The model made reliable predictions (average correlation of 0.85 between predicted and subsequently tested expression values). Even regulations predicted to be non-monotonic were successfully validated by PCR in new sets of experiments. Transient patterns of gene regulation were identified from model predictions. They pointed towards activation of Wnt signaling as a candidate pathway leading to a redirection of differentiation away from neuroepithelial cells towards neural crest. Intervention experiments, using a Wnt/beta-catenin antagonist, led to a phenotypic rescue of this disturbed differentiation. Thus, our broadly applicable model allows the analysis of transcriptome changes in complex time/perturbation matrices.

description: Transient near-fields around metallic nanotips drive many applications, including the generation of ultrafast electron pulses and their use in electron microscopy. We have investigated the electron emission from a gold nanotip driven by mid-infrared few-cycle laser pulses. We identify a low-energy peak in the kinetic energy spectrum and study its shift to higher energies with increasing laser intensities from $1.7$ to $3.7\cdot10^{11} \mathrm{W}/\mathrm{cm}^2$. The experimental observation of the upshift of the low-energy peak is compared to a simple model and numerical simulations, which show that the decay of the near-field on a nanometer scale results in non-adiabatic transfer of the ponderomotive potential to the kinetic energy of emitted electrons and in turn to a shift of the peak. We derive an analytic expression for the non-adiabatic ponderomotive shift, which, after the previously found quenching of the quiver motion, completes the understanding of the role of inhomogeneous fields in strong-field photoemission from nanostructures.

description: We study the effect of a linear tunneling coupling between 2D systems, each separately exhibiting the topological Berezinskii-Kosterlitz-Thouless (BKT) transition. In the uncoupled limit, there are two phases: one where the 1-body correlation functions are algebraically decaying and the other with exponential decay. When the linear coupling is turned on, a third BKT-paired phase emerges, in which 1-body correlations are exponentially decaying, while 2-body correlation functions exhibit power-law decay. We perform numerical simulations in the paradigmatic case of two coupled XY models at finite temperature, finding that for any finite value of the interlayer coupling, the BKT-paired phase is present. We provide a picture of the phase diagram using a renormalization group approach.

Quantal Andreev billiards: Semiclassical approach to mesoscale oscillations in the density of states

description: Andreev billiards are finite, arbitrarily-shaped, normal-state regions, surrounded by superconductor. At energies below the superconducting gap, single-quasiparticle excitations are confined to the normal region and its vicinity, the essential mechanism for this confinement being Andreev reflection. This Paper develops and implements a theoretical framework for the investigation of the short-wave quantal properties of these single-quasiparticle excitations. The focus is primarily on the relationship between the quasiparticle energy eigenvalue spectrum and the geometrical shape of the normal-state region, i.e., the question of spectral geometry in the novel setting of excitations confined by a superconducting pair-potential. Among the central results of this investigation are two semiclassical trace formulas for the density of states. The first, a lower-resolution formula, corresponds to the well-known quasiclassical approximation, conventionally invoked in settings involving superconductivity. The second, a higher-resolution formula, allows the density of states to be expressed in terms of: (i) An explicit formula for the level density, valid in the short-wave limit, for billiards of arbitrary shape and dimensionality. This level density depends on the billiard shape only through the set of stationary-length chords of the billiard and the curvature of the boundary at the endpoints of these chords; and (ii) Higher-resolution corrections to the level density, expressed as a sum over periodic orbits that creep around the billiard boundary. Owing to the fact that these creeping orbits are much longer than the stationary chords, one can, inter alia, hear the stationary chords of Andreev billiards.

Novel injection and targetry in laser wakefield acceleration
Creators: name: Rozario, Savio Vinod
Publisher: name: Imperial College London
Year: 2019

description: This thesis presents experimental research into laser wakefield accelerators. It is divided into two main themes; the first was the examination of a novel injection mechanism for wakefield acceleration using a clustered medium and the second was the use of density-length scans to study the optimum conditions for different injection mechanisms. First, we address an experiment that examined cluster injection, where methane was used for the clustering medium. A clustered target, with cluster radii of 5-10nm, were observed to generate electron beams with 60+/-2.5 pC, which was an increase in the charge of the electron beam by a factor of 24 when compared to molecular methane in a gas cell, when driven with a 10TW laser pulse. The clustered target generates 20% more charge, than the highest charge beams from self-injection in the gas cell. This demonstrates that the injection mechanism was distinct from ionisation injection. Next, a clustered target was examined at a higher power laser facility, where a 100TW laser pulse was used to drive a wakefield accelerator. In the same gas jet, helium (SI), helium + 1% nitrogen (II) and methane (CI) were used. The total charge of the electron beam generated for all three targets was 100pC. For cluster injection at higher densities, the electron beam was observed to develop transverse oscillations which were attributed to the onset of the hosing instability. This oscillation also coincides with a large increase in x-ray flux. The highest flux betatron beam from CI was 38% higher than II and 8 times greater than SI. The latter two chapters of this thesis discuss a multi-parameter scan, where density and length were varied sequentially. For self-injection, the highest beam energy observed was 210+/-19MeV and the highest beam charge measured was 50+/-2.3 pC and the lowest beam divergence measured was 1.5+/-0.1 mrad$. The final chapter examined a density-length parameter scan using ionisation injection. The maximum energy observed was 159+/-22MeV, the highest charge measured was 35.7+/-3.4pC and the lowest divergence measured was 1.6+/-0.1 mrad. The lowest eccentricity for II was measured to be 23% lower for II than SI. We conclude that for the highest charge beam, SI in a gas cell or CI is the ideal target. Electron beams from SI reach the highest energies and the lowest divergence. Electron beams from II have the lowest eccentricity, pointing deviation and transverse momentum.
Phase transitions and macroscopic limits in a BGK model of body-attitude coordination

description: In this article we investigate the phase transition phenomena that occur in a model of self-organisation through body-attitude coordination. Here, the body-attitude of an agent is modelled by a rotation matrix in $\mathbb{R}^3$ as in [Degond, Frouvelle, Merino-Aceituno, 2017]. The starting point of this study is a BGK equation modelling the evolution of the distribution function of the system at a kinetic level. The main novelty of this work is to show that in the spatially homogeneous case, self-organisation may appear or not depending on the local density of agents involved. We first exhibit a connection between body-orientation models and models of nematic alignment of polymers in higher dimensional space from which we deduce the complete description of the possible equilibria Then, thanks to a gradient-flow structure specific to this BGK model, we are able to prove the stability and the convergence towards the equilibria in the different regimes. We then derive the macroscopic models associated to the stable equilibria in the spirit of [Degond, Frouvelle, Merino-Aceituno, 2017] and [Degond, Frouvelle, Liu, 2015].

description: Introduction: Oral health and oral health-related quality of life (OHrQL) of residents in German long-term residential care (LRC) are poor. We will develop an evidence-based catalogue of interventions ('Oral Health Toolbox') and provide care-accompanying reinstruction and remotivation of nursing staff by dental assistants (DA). We hypothesise that such intervention will significantly improve OHrQL, daily oral hygiene/care behaviour and is cost-effective. Methods and analysis: A scoping review will be used to identify possible intervention components. Mixed methods will be used to identify barriers and enablers of oral hygiene and care in German LRC. The result will be the 'Oral Health Toolbox', a two-phased instrument supporting both initial intervention allocation to improve oral health/hygiene and reinstruction/remotivation. A two-arm clustered, randomised controlled trial (ratio of 1:1 via block randomisation) will be performed in LRC in Rhineland-Palatinate, Germany. Each nursing home represents a cluster. Based on a feasibility study, considering clustering and possible attrition, we aim at recruiting 618 residents in 18 clusters. In the intervention group, dentists will assign one or more intervention component from the box (phase 1). During follow-up, nursing staff will be reinstructed and remotivated by DA, who use the box to decide how to maintain the intervention (phase 2). In the control group residents will receive care as usual. The primary outcome, OHrQL, will be measured using the General Oral Health Assessment Index. Secondary outcomes include pain condition, general health-related quality of life, caries increment, oral/prosthetic hygiene and gingival status, incidence of dental emergencies and hospitalisations, and cost-utility/effectiveness. The endpoints will be measured at baseline and after 12 months. For our primary outcome, a mixed-linear model will be used within an intention-to-treat analysis. A process evaluation using mixed methods will be conducted alongside the trial. Ethics and dissemination: Ethical approval by the University of Kiel was granted (D480/18). Trial registration number: NCT04140929.

description: A convex parameterization of internally stabilizing controllers is fundamental for many controller synthesis procedures. The celebrated Youla parameterization relies on a doubly-coprime factorization of the system, while the recent system-level and input-output characterizations require no doubly-coprime factorization but a set of equality constraints for achievable closed-loop responses. In this paper, we present explicit affine mappings among Youla, system-level and input-output parameterizations. Two direct implications of the affine mappings are 1) any convex problem in Youla, system level, or input-output parameters can be equivalently and convexly formulated in any other one of these frameworks, including the convex system-level synthesis (SLS); 2) the condition of quadratic invariance (QI) is sufficient and necessary for the classical distributed control problem to admit an equivalent convex reformulation in terms of Youla, system-level, or input-output parameters.

Essential Role of the Cooperative Lattice Distortion in the Charge, Orbital and Spin Ordering in doped Manganites

description: The role of lattice distortion in the charge, orbital and spin ordering in half doped manganites has been investigated. For fixed magnetic ordering, we show that the cooperative lattice distortion stabilize the experimentally observed ordering even when the strong on-site electronic correlation is taken into account. Furthermore, without invoking the magnetic interactions, the cooperative lattice distortion alone may lead to the correct charge and orbital ordering including the charge stacking effect, and the magnetic ordering can be the consequence of such a charge and orbital ordering. We propose that the cooperative nature of the lattice distortion is essential to understand the complicated charge, orbital and spin ordering observed in doped manganites.

description: We generalize the worldline formalism to include spin 1/2 fields coupled to gravity. To this purpose we first extend dimensional regularization to supersymmetric nonlinear sigma models in one dimension. We consider a finite propagation time and find that dimensional regularization is a manifestly supersymmetric regularization scheme, since the classically supersymmetric action does not need any counterterm to preserve worldline supersymmetry. We apply this regularization scheme to the worldline description of Dirac fermions coupled to gravity. We first compute the trace anomaly of a Dirac fermion in 4 dimensions, providing an additional check on the regularization with finite propagation time. Then we come to the main topic and consider the one-loop effective action for a Dirac field in a gravitational background. We describe how to represent this effective action as a worldline path integral and compute explicitly the one- and two-point correlation functions, i.e. the spin 1/2 particle contribution to the graviton tadpole and graviton self-energy. These results are presented for the general case of a massive fermion. It is interesting to note that in the worldline formalism the coupling to gravity can be described entirely in terms of the metric, avoiding the introduction of a vielbein. Consequently, the fermion--graviton vertices are always linear in the graviton, just like the standard coupling of fermions to gauge fields.

Trinion Conformal Blocks from Topological strings

description: In this paper we investigate the relation between conformal blocks of Liouville CFT and the topological string partition functions of the rank one trinion theory $T_2$. The partition functions exhibit jumps when passing from one chamber in the parameter space to another. Such jumps can be attributed to a change of the integration contour in the free field representation of Liouville conformal blocks. We compare the partition functions of the $T_2$ theories representing trifundamental half hypermultiplets in $N=2$, $d=4$ field theories to the partition functions associated to bifundamental hypermultiplets. We find that both are related to the same Liouville conformal blocks up to inessential factors. In order to establish this picture we combine and compare results obtained using topological vertex techniques, matrix models and topological recursion. We furthermore check that the partition functions obtained by gluing two $T_2$ vertices can be represented in terms of a four point Liouville conformal block. Our results indicate that the $T_2$ vertex offers a useful starting point for developing an analog of the instanton calculus for SUSY gauge theories with trifundamental hypermultiplets.

Local Defect in Metallic Quantum Critical Systems

description: We present a theory of a single point, line or plane defect coupling to the square of the order parameter in a metallic system near a quantum critical point at or above its upper critical dimension. At criticality, a spin droplet is nucleated around the defect with droplet core size determined by the strength of the defect potential. Outside the core a universal slowly decaying tail of the droplet is found, leading to many dissipative channels coupling to the droplet and to a complete suppression of quantum tunneling. We propose an NMR experiment to measure the impurity-induced changes in the local spin susceptibility.

description: Aim Quantitative and kinetic insights into the drug exposure‐disease response relationship might enhance our knowledge on loss of response and support more effective monitoring of inflammatory activity by biomarkers in patients with inflammatory bowel disease (IBD) treated with infliximab (IFX). This study aimed to derive recommendations for dose adjustment and treatment optimisation based on mechanistic characterisation of the relationship between IFX serum concentration and C‐reactive protein (CRP) concentration. Methods Data from an investigator‐initiated trial included 121 patients with IBD during IFX maintenance treatment. Serum concentrations of IFX, antidrug antibodies (ADA), CRP, and disease‐related covariates were determined at the mid‐term and end of a dosing interval. Data were analysed using a pharmacometric nonlinear mixed‐effects modelling approach. An IFX exposure‐CRP model was generated and applied to evaluate dosing regimens to achieve CRP remission. Results The generated quantitative model showed that IFX has the potential to inhibit up to 72% (9% relative standard error [RSE]) of CRP synthesis in a patient. IFX concentration leading to 90% of the maximum CRP synthesis inhibition was 18.4 μg/mL (43% RSE). Presence of ADA was the most influential factor on IFX exposure. With standard dosing strategy, ≥55% of ADA+ patients experienced CRP nonremission. Shortening the dosing interval and co‐therapy with immunomodulators were found to be the most beneficial strategies to maintain CRP remission. Conclusions With the generated model we could for the first time establish a robust relationship between IFX exposure and CRP synthesis inhibition, which could be utilised for treatment optimisation in IBD patients.

description: We study the fluctuation conductivity of superconducting granular metals at low temperatures and strong magnetic field destroying the Cooper pairs. Explicit calculations are performed for larger values of the coupling between the grains than those considered in previous works. We show that in a broad region of the coupling constants the superconducting fluctuations still significantly reduce the conductivity leading to a negative magnetoresistance.

description: It is common practice nowadays to use multiple social networks for different social roles. Although this, these networks assume differences in content type, communications and style of speech. If we intend to understand human behaviour as a key-feature for recommender systems, banking risk assessments or sociological researches, this is better to achieve using a combination of the data from different social media. In this paper, we propose a new approach for user profiles matching across social media based on embeddings of publicly available users' face photos and conduct an experimental study of its efficiency. Our approach is stable to changes in content and style for certain social media.
