description: Fluoropolymers, known for their high dielectric permittivity, are extensively studied for nanocomposite energy storage. However, nanoparticle incorporation introduces defects, making the fabrication of thin films able to withstand high electric fields challenging. Consequently, research on films thinner than 10 µm remains limited, despite their potential for effective polarization at lower voltages. Among fluoropolymers, P(VDF-TrFE) offers well-established and easy thin film deposition via spin coating, making it ideal for nanocomposite thin films. This study presents the synthesis and energy storage characterization of P(VDF-TrFE) nanocomposite thin films with a thickness of ∼1 µm, demonstrating enhanced energy storage performance. This is achieved by adding a nanoparticle mixture of carboxymethyl cellulose nanofibers and polydopamine-coated BTO into the P(VDF-TrFE) polymer matrix, resulting in a 60% increase in energy density and a twofold enhancement in energy efficiency. A direct correlation between the nanoparticle concentration and the observed enhancements in dielectric and ferroelectric characteristics is established.

description: We study "minimal degree" complete bases of duality- and "horizontal"- invariant homogeneous polynomials in the flux representation of two-centered black hole solutions in two classes of D=4 Einstein supergravity models with symmetric vector multiplets' scalar manifolds. Both classes exhibit an SL(2,R) "horizontal" symmetry. The first class encompasses N=2 and N=4 matter-coupled theories, with semi-simple U-duality given by SL(2,R) x SO(m,n); the analysis is carried out in the so-called Calabi-Vesentini symplectic frame (exhibiting maximal manifest covariance) and until order six in the fluxes included. The second class, exhibiting a non-trivial "horizontal" stabilizer SO(2), includes N=2 minimally coupled and N=3 matter coupled theories, with U-duality given by the pseudo-unitary group U(r,s) (related to complex flux representations). Finally, we comment on the formulation of special Kaehler geometry in terms of "generalized" groups of type E7.

description: More than 54% of the world population lives in urban areas, and this percentage is projected to increase rapidly in future years. This growth significantly affects the hydrological cycle, which translates into social and economic costs due to urban flooding. This thesis develops a procedure to evaluate the current storm water infrastructure using Airborne LiDAR data. This evaluation is essential to mitigate and prevent the effect of floods in urban areas. Airborne LiDAR data provides the elevation data necessary to characterize the elements involved in the storm water system. The processing of this data, digitization, and characterization of the storm drainage system is computed with ArcGIS, Geographic Information System (GIS) software. Scenarios for 4 return periods (2, 10, 25 and 100 years) are modeled using StormCAD in order to evaluate the capacity of the stormwater sewer system in the northwest area of The University of Texas at Austin main campus. The performance of the drainage system might work under strain for a 100-year storm event; therefore, it is suggested to modify the pipe sizes to prevent flooding in the area analyzed. The results indicate that the methodology proposed for evaluating the current conditions of a stormwater drainage system produces valid results, but can be improved using Ground-based LiDAR data.

description: We investigate the mean electromotive force in the kinematic framework, that is, ignoring the back-reaction of the magnetic field on the fluid velocity, under the assumption of axisymmetric turbulence determined by the presence of either rotation, density stratification, or both. We use an analogous approach for the mean passive scalar flux. As an alternative to convection, we consider forced turbulence in an isothermal layer. When using standard ansatzes, the mean magnetic transport is then determined by nine, and the mean passive scalar transport by four coefficients. We give results for all these transport coefficients. We use the test-field method and the test-scalar method, where transport coefficients are determined by solving sets of equations with properly chosen mean magnetic fields or mean scalars. These methods are adapted to mean fields which may depend on all three space coordinates. We find the anisotropy of turbulent diffusion to be moderate in spite of rapid rotation or strong density stratification. Contributions to the mean electromotive force determined by the symmetric part of the gradient tensor of the mean magnetic field, which were ignored in several earlier investigations, turn out to be important. In stratified rotating turbulence, the $α$ effect is strongly anisotropic, suppressed along the rotation axis on large length scales, but strongly enhanced at intermediate length scales. Also the $\OO\times\meanJJ$ effect is enhanced at intermediate length scales. The turbulent passive scalar diffusivity is typically almost twice as large as the turbulent magnetic diffusivity. Both magnetic and passive scalar diffusion are slightly enhanced along the rotation axis, but decreased if there is gravity.

description: We study the ultradiscrete analogue of Lax pair proposed by Willox et al. This "pair" is a max-plus linear system comprising four equations. Our starting point is to treat this system as a combination of two max-plus eigenproblems, with two additional constraints. Though infinite-dimensional, these two eigenproblems can be treated by means of the "standard" max-plus spectral theory. In particular, any solution to the system can be described as a max-linear combination of fundamental eigenvectors associated with each soliton. We then describe the operation of undressing using pairs of fundamental eigenvectors. We also study the solvability of the complete system of four equations as proposed by Willox et al.

Advanced Robust Control Design For High Speed Tilting Trains

Publisher: name: University of Lincoln

Subjects: H100 - General engineering

description: Tilting is a worldwide accepted technology concept in railway transportation. Theparticular benefit from tilting trains use is reduction in journey times due to speedincrease on track corners (while maintaining acceptable passenger comfort), a pointthat facilitates improved customer service. An additional benefit is cost effectivenessdue to the train running on existing rail tracks. Many countries opted to using tiltingtrains as means of fast public transportation (UK, USA, Canada, Sweden, Norway,Switzerland, Germany, Japan).The industrial norm of tilting high speed trains is that of precedence tilt wherebypreview tilt enabling signals are used to provide the required information to thevehicles (it can also use a combination of track database information or GPS but theconcept is the same). Precedence tilt tends to be complex (mainly due to the signalinterconnections between vehicles and the advanced signal processing required formonitoring). Research studies of earlier than precedence schemes,i.e. the so-callednulling-type schemes whereby local-per-vehicle signals are used to provide tilt (adisturbance rejection-scheme although tends to suffer from inherent delays in thecontrol feedback), are still an important research aim due to the simple natureand most importantly due to the more straightforward fault detection compared toprecedence. Use of nulling-type tilt has been supported by recent studies in thiscontext.The research presented in this thesis highly contributes to simplified single-inputsingle-output robust tilt control using the simplest rail vehicle tilt structure, i.e. anActive Anti-Roll Bar. Proposed are both robust conventional (integer-type) controlapproaches and non-conventional (non-integer) schemes with a rigorous investigation of the difficult to achieve deterministic/stochastic tilt trade-off. Optimizationhas been used extensively for the designs. A by-product of the work is the insightprovided into the relevant tilting train model Non Minimum Phase characteristicsand its link to uncertainty for control design. Work has been undertaken usingMatlab, including proper assessment of tilt ride quality considerations.
Dimensional regularization applied to nuclear matter with a zero--range interaction

Year: 2012

description: We apply the dimensional regularization procedure to treat an ultraviolet divergence occurring in the framework of the nuclear many-body problem. We consider the second--order correction (beyond the mean-field approximation) to the equation of state of nuclear matter with a zero-range effective interaction. The unphysical ultraviolet divergence that is generated at second order by the zero range of the interaction is removed by the regularization technique and the regularized equation of state (mean-field + second-order contributions) is adjusted to a reference equation of state. The main practical advantage of this procedure, with respect to a cutoff regularization, is to provide a unique set of parameters for the adjusted effective interaction. This occurs because the regularized second-order correction does not contain any cutoff dependence. The encouraging results found in this work indicate that such an elegant technique to generate regularized effective interactions is likely to be applied in future to finite nuclei in the framework of beyond mean-field models.

title: DEPRECATED: Implicit and Explicit Processes in Multiple Cue Judgement
Creators: name: Rolison, Jonathan James
Publisher: name: University of Plymouth
Year: 2009

description: Making judgements often involves integrating multiple pieces of information, or cues, in the environment. While experts, such as physicians, are able to make accurate judgements from multiple cues, they often have poor insight into how they make their inferences. This provides some indication that judgement is influenced by knowledge that is implicit and inaccessible to verbal report. In the present thesis, the cognitive processes involved in multiple cue judgement were explored by training participants on a small number of novel cues using the multiple cue probability learning (MCPL) paradigm. In a training phase, participants predicted a criterion and received outcome feedback in response to each judgement. Learning and judgement in these tasks is often assumed to draw on explicit hypothesis-testing processes. However, a great deal of research suggests that implicit as well as explicit processes can contribute to performance on complex tasks. In eight experiments, several methods were used to examine the role of explicit and implicit processes in multiple cue judgement. While concurrent working memory loads failed to disrupt judgements after learning, we nevertheless found clear evidence that explicit processing is involved in the learning of negative, but not positive cues. Performance on such tasks was correlated with individual differences in working memory capacity, as well as measures of explicit knowledge obtained in the learning process. The results are discussed with respect to dual process theories of learning, judgement, and reasoning. The findings of the present thesis indicate that multiple cue judgement is best viewed within a dual process framework.

description: Memristive systems, namely resistive systems with memory, are attracting considerable attention due to their ubiquity in several phenomena and technological applications. Here, we show that even the simplest one-dimensional network formed by the most common memristive elements with voltage threshold bears non-trivial physical properties. In particular, by taking into account the single element variability we find i) dynamical acceleration and slowing down of the total resistance in adiabatic processes, ii) dependence of the final state on the history of the input signal with same initial conditions, iii) existence of switching avalanches in memristive ladders, and iv) independence of the dynamics voltage threshold with respect to the number of memristive elements in the network (scale invariance). An important criterion for this scale invariance is the presence of memristive systems with very small threshold voltages in the ensemble. These results elucidate the role of memory in complex networks and are relevant to technological applications of these systems.

description: We introduce the eikonal approximation to study the effect of the large-scale motion of cosmic fluids on their small-scale evolution. This approach consists in collecting the impact of the long-wavelength displacement field into a single or finite number of random variables, whose statistical properties can be computed from the initial conditions. For a single dark matter fluid, we show that we can recover the nonlinear propagators of renormalized perturbation theory. These are obtained with no need to assume that the displacement field follows the linear theory. Then we extend the eikonal approximation to many fluids. In particular, we study the case of two non-relativistic components and we derive their resummed propagators in the presence of isodensity modes. Unlike the adiabatic case, where only the phase of small-scale modes is affected by the large-scale advection field, the isodensity modes change also the amplitude on small scales. We explicitly solve the case of cold dark matter-baryon mixing and find that the isodensity modes induce only very small corrections to the resummed propagators.

description: The winds from a non-accreting pulsar and a massive star in a binary system collide forming a bow-shaped shock structure. The Coriolis force induced by orbital motion deflects the shocked flows, strongly affecting their dynamics. We study the evolution of the shocked stellar and pulsar winds on scales in which the orbital motion is important. Potential sites of non-thermal activity are investigated. Relativistic hydrodynamical simulations in two dimensions, performed with the code PLUTO and using the adaptive mesh refinement technique, are used to model interacting stellar and pulsar winds on scales ~80 times the distance between the stars. The hydrodynamical results suggest the suitable locations of sites for particle acceleration and non-thermal emission. In addition to the shock formed towards the star, the shocked and unshocked components of the pulsar wind flowing away from the star terminate by means of additional strong shocks produced by the orbital motion. Strong instabilities lead to the development of turbulence and an effective two-wind mixing in both the leading and trailing sides of the interaction structure, which starts to merge with itself after one orbit. The adopted moderate pulsar-wind Lorentz factor already provides a good qualitative description of the phenomena involved in high-mass binaries with pulsars, and can capture important physical effects that would not appear in non-relativistic treatments. Simulations show that shocks, instabilities, and mass-loading yield efficient mass, momentum, and energy exchanges between the pulsar and the stellar winds. This renders a rapid increase in the entropy of the shocked structure, which will likely be disrupted on scales beyond the simulated ones. Several sites of particle acceleration and low- and high-energy emission can be identified. Doppler boosting will have significant and complex effects on radiation.

description: Developing behaviours for interaction with objects close to the body is a primary goal for any organism to survive in the world. Being able to develop such behaviours will be an essential feature in autonomous humanoid robots in order to improve their integration into human environments. Adaptable spatial abilities will make robots safer and improve their social skills, human-robot and robot-robot collaboration abilities. This work investigated how a humanoid robot can explore and create action-based representations of its peripersonal space, the region immediately surrounding the body where reaching is possible without location displacement. It presents three empirical studies based on peripersonal space findings from psychology, neuroscience and robotics. The experiments used a visual perception system based on active-vision and biologically inspired neural networks. The first study investigated the contribution of binocular vision in a reaching task. Results indicated the signal from vergence is a useful embodied depth estimation cue in the peripersonal space in humanoid robots. The second study explored the influence of morphology and postural experience on confidence levels in reaching assessment. Results showed that a decrease of confidence when assessing targets located farther from the body, possibly in accordance to errors in depth estimation from vergence for longer distances. Additionally, it was found that a proprioceptive arm-length signal extends the robot’s peripersonal space. The last experiment modelled development of the reaching skill by implementing motor synergies that progressively unlock degrees of freedom in the arm. The model was advantageous when compared to one that included no developmental stages. The contribution to knowledge of this work is extending the research on biologically-inspired methods for building robots, presenting new ways to further investigate the robotic properties involved in the dynamical adaptation to body and sensing characteristics, vision-based action, morphology and confidence levels in reaching assessment.

description: We show that radio bursts from cusps on superconducting strings are linearly polarized, thus, providing a signature that can be used to distinguish them from astrophysical sources. We write the event rate of string-generated radio transients in terms of observational variables, namely, the event duration and flux. Assuming a canonical set of observational parameters, we find that the burst event rate can be quite reasonable, e.g., order ten a year for Grand Unified strings with 100 TeV currents, and a lack of observed radio bursts can potentially place strong constraints on particle physics models.

description: Dispersal is a key process in ecology and evolutionary biology, as it shapes biodiversity patterns over space and time. Mounting evidence is showing that attitude to disperse is unevenly distributed among individuals within animal populations, and that individual personality can have pivotal roles in the shaping of this attitude. Here, we contribute to the study of the genetic underpinnings of dispersal-related behavioral variation by assembling and annotating the first de novo transcriptome of the head tissues of Salamandra salamandra. Although dispersal occurs mostly during the post-metamorphic terrestrial life stage in this species, variation in dispersal-related personality traits is already evident at the aquatic larval stage, making it an excellent candidate species for studies of carry-over effects. We employed a structured pipeline to de-novo assemble and annotate transcripts from RNA-Seq in a set of individuals representative of distinct behavioral profiles. We obtained 1,153,432,918 reads, which were successfully de novo assembled and annotated. The high-quality assembly was confirmed by comparing BUSCO, DETONATE and TransRate with the S. salamandra dataset. By aligning the contigs against the de novo transcriptome we obtained a percentage of mapping higher than 94%. The homology annotation performed with DIAMOND led to 153,048 (blastx) and 95,942 (blastp) shared contigs, annotated on NCBI nr, Swiss-Prot and TrEMBL. The domain and site protein prediction made with InterProScan led to 9850 GO-annotated contigs. This de-novo transcriptome represents reliable reference for whole transcriptome and proteome studies of other amphibians, for designing primers to clone specific genes or monitor their expression, and for analyzing comparative gene expression profiles between alternative behavioral types.

Characterization of verteporfin as an inhibitor of autophagosome formation and its therapeutic potential in cancer
Creators: name: Donohue, Elizabeth
Publisher: name: University of British Columbia
Year: 2013

description: Autophagy is a cellular “self-eating” process that enables cells to degrade and recycle cytoplasmic materials both as a housekeeping mechanism and in response to extracellular stress. Based on preclinical studies, autophagy promotes cell survival in the nutrient-deprived tumour environment and in response to several cancer therapy agents, making it a prospective therapeutic target. Due to a lack of pharmacologically suitable and selective autophagy inhibitors, a phenotypic automated fluorescence microscopy assay was designed and used to screen > 3,500 drugs and pharmacological agents for novel inhibitors of autophagosome accumulation. Verteporfin, a benzoporphyrin derivative used in photodynamic therapy, was the only active compound identified. As a photosensitizer, verteporfin generates large amounts of singlet oxygen upon light irradiation, which elicits a cell-death response. In the absence of light activation, verteporfin is nontoxic and inhibits starvation- and drug-induced autophagy. Biochemical and microscopy assays revealed that verteporfin prevents autophagic sequestration and degradation downstream of LC3 lipidation and membrane association. p62 is a scaffold protein that oligomerizes and links poly-ubiquitinated proteins to the autophagosome membrane by binding LC3, thus delivering both its cargo and itself for lysosomal degradation. Western blot analysis revealed that verteporfin produces SDS-stable high-MW p62, which is highly oxidized, and is likely a product of p62 crosslinking. The mechanism of high-MW p62 generation by verteporfin was discovered to be low-level singlet oxygen production, and the appearance of high-MW p62 correlated with autophagy inhibition. p62 co-immunoprecipitation experiments revealed that its association with EGFP-LC3 was not affected by verteporfin, but binding to poly-ubiquitinated cargo was disrupted. Therefore, non-photoactivated verteporfin generates low-level singlet oxygen that induces p62 oxidation and high-MW products that may interfere with autophagosome formation. Verteporfin was used to evaluate the therapeutic potential of autophagy inhibition using two different tumour xenograft models. Verteporfin did not show anti-tumour activity in a JIMT-1 breast cancer model, but it did enhance the anti-tumour and survival effects conferred by gemcitabine in a BxPC-3 pancreatic cancer model. The characterization of an early autophagy inhibitor among FDA-approved drugs that shows in vivo potential has significant implications for understanding autophagy modulation as a therapeutic strategy.
Semi-Automated Labelling of Cystoid Macular Edema in OCT Scans

description: The analysis of retinal Spectral Domain Optical Coherence Tomography (SDOCT) images by trained medical professionals can be used to provide useful insights into various diseases. It is the most popular method of retinal imaging due to its non invasive nature and the useful information it provides for making an accurate diagnosis, however there is a clear lack of publicly available data available to researchers in the domain. In this report, a deep learning approach for automating the segmentation of Cystoid Macular Edema (fluid) in retinal OCT B-Scan images is presented that is consequently used for volumetric analysis of OCT scans. This solution is a fast and accurate semantic segmentation network which makes use of a shortened encoderdecoder UNet-like architecture with an integrated DenseASPP module and Attention Gate for producing an accurate and refined retinal fluid segmentation map. The network is evaluated against both publicly and privately available datasets; on the former the network achieved a Dice coefficient of 0.804, thus making it the current best performing approach on this dataset and on the very small and challenging private dataset, it achieved a score of 0.691. Due to the issue presented by a lack of publicly available data in this domain, a Graphical User Interface that aims to semi-automate the labelling process of OCT images was also created, thus greatly simplifying the process of dataset creation and potentially leading to an increase in labelled data production.

description: We present gauge theory completions of Wess-Zumino models admitting supersymmetry breaking vacua with spontaneously broken R-symmetry. Our models are simple deformations of generalized ITIY models, a supersymmetric theory with gauge group Sp(N), N+1 flavors plus singlets, with a modified tree level superpotential which explicitly breaks (part of) the global symmetry. Depending on the nature of the deformation, we obtain effective O'Raifeartaigh-like models whose pseudomoduli space is locally stable in a neighborhood of the origin of field space, or in a region not including it. Hence, once embedded in direct gauge mediation scenarios, our models can give low energy spectra with either suppressed or unsuppressed gaugino mass.

description: We describe a method for creating a three-dimensional analogue to Rashba spin-orbit coupling in systems of ultracold atoms. This laser induced coupling uses Raman transitions to link four internal atomic states with a tetrahedral geometry, and gives rise to a Dirac point that is robust against environmental perturbations. We present an exact result showing that such a spin-orbit coupling in a fermionic system always rise to a molecular bound state.

title: DEPRECATED: THE DEVELOPMENT OF THE PALMAR SWEAT INDEX AS AN APPLIED MEASURE IN CLINICAL PSYCHOLOGY
Creators: name: CLEMENTS, KEITH JOHN
Publisher: name: University of Plymouth
Year: 1992

description: Five studies are described, examining the validity of the Palmar Sweat Index (PSI) as an alternative to traditional measures of electrodermal activity (EDA). A review of research using the PSI identified tour topics which needed to be addressed, before the PSI could be accepted as an alternative to measures of EDA. The first of these topics concerns the reliability of the PSI. A preliminary analysis confirmed that the PSI could be scored reliably. The second topic to be examined, was the relationship between the PSI and measures of EDA. The PSI was found to correlate significantly with several parameters of EDA. These results provide some support for models of EDA involving a single effector. More importantly, the PSI response was observed to show rapid recovery, and in one study the PSI was observed to show adaptation over the course of the session, while skin conductance level did not. The difference in the temporal patterning of the responses shown by the two measures provides an explanation for previous reports of a dissociation between the PSI and EDA. The final topics to be examined concerned the effects of psychological stress and anxiety, respectively, on the PSI. Stressful cognitive tasks were observed to lead to increased palmar sweating. Previous claims that the PSI may decrease in response to stress were not supported. More ecologically-valid stressors were less consistently associated with elevated levels of sweat gland activity. There was some support for a relationship between the PSI and experienced anxiety. It is suggested that this may explain the raised sweat gland activity observed during stressful tasks. Data are also presented from three collaborative studies. This data was collected by other workers and demonstrates the utility of the PSI for applied clinical research.

description: We present Las Vegas algorithms for constructive recognition and constructive membership testing of the Ree groups 2G_2(q) = Ree(q), where q = 3^{2m + 1} for some m > 0, in their natural representations of degree 7. The input is a generating set X. The constructive recognition algorithm is polynomial time given a discrete logarithm oracle. The constructive membership testing consists of a pre-processing step, that only needs to be executed once for a given X, and a main step. The latter is polynomial time, and the former is polynomial time given a discrete logarithm oracle. Implementations of the algorithms are available for the computer algebra system MAGMA.

description: We give a new adaptive method for selecting the number of upper order statistics used in the estimation of the tail of a distribution function. Our approach is based on approximation by an exponential model. The selection procedure consists in consecutive testing for the hypothesis of homogeneity of the estimated parameter against the change-point alternative. The selected number of upper order statistics corresponds to the first detected change-point. Our main results are non-asymptotic and state optimality of the proposed method in the "oracle" sense.

description: Experience is an important asset in almost any professional activity. In basketball, there is believed to be a positive association between coaching experience and effective use of team timeouts. Here, we analyze both the extent to which a team's change in scoring margin per possession after timeouts deviate from the team's average scoring margin per possession---what we called timeout factor, and the extent to which this performance measure is associated with coaching experience across all teams in the National Basketball Association over the 2009-2012 seasons. We find that timeout factor plays a minor role in the scoring dynamics of basketball. Surprisingly, we find that timeout factor is negatively associated with coaching experience. Our findings support empirical studies showing that, under certain conditions, mentors early in their careers can have a stronger positive impact on their teams than later in their careers.

description: The single production of fourth family sneutrino $\tildeν_{4}$ via R-parity violating interactions in electron-positron collisions has been investigated. We study the decays of $\tildeν_{4}$ into different flavor dilepton $e^{\pm}μ^{\mp}$ via R-parity violation. It is shown that R-parity violating couplings $(λ_{411},λ_{412})$ down to 0.001 will be reachable at future linear colliders which would provide better accuracy comparing to the indirect measurements as complementary to the LHC results.

description: It is sometimes purported that one of the factors affecting a firm's value is its capital structure. The event of the 1997 Asian financial crisis was expected to affect the firms' gearing level as the firms' earnings deteriorated and the capital market collapsed. The main objective of this research is to examine empirically the determinants of the capital structure of Malaysian firms. The main additional aim is to study the capital structure pattern following the 1997 financial crisis. Empirical tests were conducted on two different data sets: the first data set is the published data extracted from Datastream and consists of: 572 companies listed on the Kuala Lumpur Stock Exchange (KLSE) between 1994 and 2000. The second data set comprises finance managers' responses to a questionnaire survey. Chi-square, Kruskal-Wallis, ANOVA, multiple regression, stepwise regression and logistic regression were utilised to analyse the data. The multiple regression analysis was employed to find the determinants of the capital structure using various account data items provided by Datastream. The gearing differences between the two boards and within the sectors were also analysed using ANOVA and Krukal-Wall is tests. The panel data were evaluated with regard to the gearing pattern following the 1997 currency crisis. Overwhelming evidence on profit was found, with past profitability being the major determinant of gearing. In particular was the support for pecking order theory, in that finance managers had given internal funds the highest priority, followed by debt and equity as a last option. The statistical analysis found a strong negative correlation between liquidity and the gearing ratio for both boards, implying firms considered highly the excess current assets for funding, a conservative approach towards debt management policy. On the other hand, taxation items were not highly significant in capital structure decisions. The results indicate the existence of gearing differences between the main board and the second board gearing with high debt levels employed by second board companies. However, the second board's high gearing is dominated largely by short to medium term bank credit. Differences were also significant between different sectors of companies listed on the main board. Firms' gearing ratios increased significantly following the 1997 financial crisis, and the gearing tended to increase where the company's share prices were highly sensitive towards currency volatility. Also inflation is found to influence the changes in actual and target gearing ratios following the crisis. Recent emphasis on the development of private debt securities may affect the findings of this research in the near future.
