description: We present a mesoscale description of deformations and defects in thin, flexible sheets with crystalline order, tackling the interplay between in-plane elasticity, out-of-plane deformation, as well as dislocation nucleation and motion. Our approach is based on the Phase-Field Crystal (PFC) model, which describes the microscopic atomic density in crystals at diffusive timescales, naturally encoding elasticity and plasticity effects. In its amplitude expansion (APFC), a coarse-grained description of the mechanical properties of crystals is achieved. We introduce surface PFC and surface APFC models in a convenient height-function formulation encoding deformation in the normal direction. This framework is proven consistent with classical aspects of strain-induced buckling, defect nucleation on deformed surfaces, and out-of-plane relaxation near dislocations. In particular, we benchmark and discuss the results of numerical simulations by looking at the continuum limit for buckling under uniaxial compression and at evidence from microscopic models for deformation at defects and defect arrangements, demonstrating the scale-bridging capabilities of the proposed framework. Results concerning the interplay between lattice distortion at dislocations and out-of-plane deformation are also illustrated by looking at the annihilation of dislocation dipoles and systems hosting many dislocations. With the novel formulation proposed here, and its assessment with established approaches, we envision applications to multiscale investigations of crystalline order on deformable surfaces.

description: We present a careful study of accelerating black holes in anti-de Sitter spacetime, formulating the thermodynamics and resolving discrepancies that have appeared in previous investigations of the topic. We compute the dual stress-energy tensor for the spacetime and identify the energy density associated with a static observer at infinity. The dual energy-momentum tensor can be written as a three-dimensional perfect fluid plus a non-hydrodynamic contribution with a universal coefficient which is given in gauge theory variables. We demonstrate that both the holographic computation and the method of conformal completion yield the same result for the mass. We compare to previous work on black funnels and droplets, showing that the boundary region can be endowed with non-compact geometry, and comment on this novel holographic dual geometry.

description: The DENIS survey is currently imaging the entire southern sky in the I, J, and K wavebands. The current star/galaxy separation algorithm is presented and the galaxy counts are nearly perfectly Euclidean. 95% complete and reliable galaxy samples with better than 0.2 magnitude photometry should include 50,000 (K < 12.0), 500,000 (J < 14.8), and 900,000 (I < 16.5) galaxies, respectively, over the full hemisphere. Two spectroscopic followups of DENIS and 2MASS galaxies are planned on the 6dF robotic multi-object spectroscopic unit, currently under construction at the AAO, and which will be mounted on the UKST Schmidt telescope: a redshift survey of roughly 120,000 NIR selected galaxies and a peculiar velocity survey of roughly 15,000 galaxies (both early-types and inclined spirals) at cz < 10,000 km/s.

The behaviour of miscible Boussinesq fountains in uniform quiescent environments
Creators: name: Burridge, Henry Charles
Publisher: name: Imperial College London
Year: 2013

description: This research focuses on the fundamental fluid mechanics of fountains. Attention is restricted to fountains formed by the vertical injection of fluid into a uniform environment of marginally differing density such that the momentum of the ejection is opposed by buoyancy. The small density dif- ference between the two miscible fluids permits dilution of the ejected fluid and, for sufficiently energetic ejections, turbulent entrainment occurs. Our experimental study of dense saline solution forced vertically upwards into a quiescent freshwater environment examines fountains arising over a broad range of source conditions. We combine experimental results with dimensional reasoning and theoretical arguments to provide meaningful and significant additions to the existing knowledge of fountain dynamics. The results presented enhance our understanding through the study of rise heights, the fluctuations in rise heights and the scale and balance of bulk fluxes within fountains over the range of source conditions. A study of transient and steady-state behaviours and associated fountain rise ratio (peak relative to mean rise heights) identifies previously unreported dynam- ics which extend published results - these include the pinch-off of the initial vortex and rise height ratios (unexpectedly) below unity. Analysis of the rise height fluctuations during the quasi-steady state provides characteristic length, time and velocity scales distinct to the varied classes of fountain flow. Our results for the rise height ratio and indeed rise height fluctuations reveal a number of differing classes of fountain behaviour; behaviour which highlights the changing and complex nature of fountains. This results in a consistent classification which extends the previous three classes of fountain behaviour to five. Some of the implications of these new behaviours to practical engineering and geophysical applications of fountains are discussed.

description: Assuming that the enhanced MeV emission from the MeV blazar PKS 0208-512 observed by COMPTEL on occasions is due to annihilation in a pair plasma, we estimate parameters of the annihilation region: its size, the number density of particles, and the variability timescale. The values we find are in accord with our present-day knowledge of emission mechanisms operating in AGNs. The constructed model implies that the blueshifted annihilation emission is an intrinsic property of all AGN jet models, and predicts an anticorrelation between the high-energy emission and the annihilation flux.

A complexity evolutionary theory for the emergence of financial and economic crises: Synchronising Gould and Minsky through von Neumann and Mandelbrot
Creators: name: Viegas, Eduardo
Publisher: name: Imperial College London
Year: 2016

description: A theoretical complexity framework to analyse the fundamental business dynamics of financial markets and economies is developed through coherently coupling selected aspects of Gould's evolutionary theory concepts to the essence of Minsky's Financial Instability Hypothesis. This framework is grounded, or articulated in quantitative terms, through mathematical methods inspired at its core by von Neumann's automata theory, and by Maldenbrot's fractal geometry. By consistently applying such framework to the analysis of the emerging features within the financial markets and economies through a range of different and diverse datasets, markets, business dynamics and research problems, an embryonic Complexity Evolutionary Theory on Financial and Economic Crises (`CETFEC') is developed. CETFEC characterises financial markets and economies as complex systems, whereby the emergence of financial crises is regarded as the natural consequence of fundamental evolutionary processes that lead relevant agents to adapt to different environmental conditions. As a result, the theory has a marked distinction that it does not pre-define, categorise or exercise a level of judgement about the behaviour of the agents within the system. CETFEC aims to identify the signals that lead the existence of the necessary conditions for the emergence of crises, rather than trying to predict the timing of crises. As a result, the nature of shocks may be either or both, endogenous and exogenous. Fundamentally it holds that the understanding of the distribution and the diversity of the agents provide essential signals to the resilience of the system.

description: We analyse the resonance conditions of a long and narrow ribbon of finite length whether it is conductive or dielectric. This is accomplished by using a full wave approach based on the material independent modes that naturally discriminates the role of the geometry and of the material. This method effectively allows the design of the material in such a way to obtain the desired resonances. Eventually, as an example, we design two quasi-one dimensional resonators based on a graphene layer and on a silicon thin film.

description: We consider periodic homogenization of boundary value problems for second-order semilinear elliptic systems in 2D of the type $$ \partial_{x_i}\left(a_{ij}^{αβ}(x/\varepsilon)\partial_{x_j}u(x)+b_i^α(x,u(x))\right)=b^α(x,u(x)) \mbox{ for } x \in Ω. $$ For small $\varepsilon>0$ we prove existence of weak solutions $u=u_\varepsilon$ as well as their local uniqueness for $\|u-u_0\|_\infty \approx 0$, where $u_0$ is a given non-degenerate weak solution to the homogenized boundary value problem, and we estimate the rate of convergence to zero of $\|u_\varepsilon-u_0\|_\infty$ for $\varepsilon \to 0$.
 Our assumptions are, roughly speaking, as follows: The functions $a_{ij}^{αβ}$ are bounded, measurable and $\mathbb{Z}^2$-periodic, the functions $b_i^α(\cdot,u)$ and $b^α(\cdot,u)$ are bounded and measurable, the functions $b_i^α(x,\cdot)$ and $b^α(x,\cdot)$ are $C^1$-smooth, and $Ω$ is a bounded Lipschitz domain in $\mathbb{R}^2$. Neither global solution uniqueness is supposed nor growth restrictions of $b_i^α(x,\cdot)$ or $b^α(x,\cdot)$ nor higher regularity of $u_0$, and cross-diffusion is allowed.
 The main tool of the proofs is an abstract result of implicit function theorem type which in the past has been applied to singularly perturbed nonlinear ODEs and elliptic and parabolic PDEs and, hence, which permits a common approach to existence, local uniqueness and error estimates for singularly perturbed problems and and for homogenization problems.
Extrinsic vs Intrinsic Criticality in Systems with Many Components

description: Biological systems with many components often exhibit seemingly critical behaviors, characterized by atypically large correlated fluctuations. Yet the underlying causes remain unclear. Here we define and examine two types of criticality. Intrinsic criticality arises from interactions within the system which are fine-tuned to a critical point. Extrinsic criticality, in contrast, emerges without fine tuning when observable degrees of freedom are coupled to unobserved fluctuating variables. We unify both types of criticality using the language of learning and information theory. We show that critical correlations, intrinsic or extrinsic, lead to diverging mutual information between two halves of the system, and are a feature of learning problems, in which the unobserved fluctuations are inferred from the observable degrees of freedom. We argue that extrinsic criticality is equivalent to standard inference, whereas intrinsic criticality describes fractional learning, in which the amount to be learned depends on the system size. We show further that both types of criticality are on the same continuum, connected by a smooth crossover. In addition, we investigate the observability of Zipf's law, a power-law rank-frequency distribution often used as an empirical signature of criticality. We find that Zipf's law is a robust feature of extrinsic criticality but can be nontrivial to observe for some intrinsically critical systems, including critical mean-field models. We further demonstrate that models with global dynamics, such as oscillatory models, can produce observable Zipf's law without relying on either external fluctuations or fine tuning. Our findings suggest that while possible in theory, fine tuning is not the only, nor the most likely, explanation for the apparent ubiquity of criticality in biological systems with many components.

Attosecond pump-probe methods for measurement of molecular hole dynamics
Creators: name: Matía Hernando, Paloma
Publisher: name: Imperial College London
Year: 2017

description: The generation of few-cycle pulses at near-infrared wavelengths is now a robust technology, as is their application to the efficient production of high-order harmonics in the extreme ultraviolet region with temporal confinement to hundreds of attoseconds. Recent years have seen considerable efforts directed to the study of electron dynamics in complex molecules in real time, with relevance to processes such as photosynthesis and radiation damage of proteins and DNA. This work describes the development of new and unique sources suited for the study of such dynamics, together with novel instrumentation and experimental methodology. This includes a pair of synchronised attosecond pulses at different photon energies in the VUV and XUV regions, which we have generated via high harmonic generation from a few-cycle NIR source and characterised with attosecond streaking. We have also explored the possibilities of sub-cycle control of these attosecond pulses by adding a second harmonic field to the high- harmonic generation process, and simultaneously characterised this second harmonic field with a novel characterisation technique known as ARIES, capable of waveform sampling at arbitrary optical wavelengths. In parallel, we have developed a few-cycle short-wavelength IR source for a UK user facility, to take advantage of the favourable wavelength scaling of the maximum photon energy achievable via high-harmonic generation. Using a commercial optical parametric amplifier and a hollow-core fibre compression system, we have generated sub-2-cycle pulses at 1750 nm, characterised via third-harmonic autocorrelation and a novel implementation of the dispersion scan technique. We have commissioned a beamline for attosecond pump-probe studies in the gas phase, including a purpose-built dual spectrometer with capabilities for simultaneous measurement of mass spectra of ions and velocity-map imaging of electrons. We have performed initial VUV-NIR pump-probe experiments on a small organic molecule, namely isopropanol, and identified a time- dependent signature as an IR-induced coupling. Finally, we have considered perspectives for future studies in attosecond pump-probe experiments with the demonstration of a two-VUV-photon process in helium performed with a moderate energy, high repetition rate attosecond source.

Influence of basin physiography on coastal–shelf sedimentary processes: Integrating ocean modeling and sedimentary facies analysis in the Miocene–Pliocene, South China Sea
Creators: name: Collins, Daniel
Publisher: name: Imperial College London
Year: 2017

description: Ancient coastal–shallow marine sedimentary rocks preserve a fragmented history of competing tidal, wave, storm and fluvial processes and changes in sedimentary environments, including the influence of variations in sea level, tectonics, climate and ocean circulation. To unravel these records, this study integrates detailed sedimentary analysis of outcrop and sub-surface data, palaeogeographic and palaeotectonic reconstructions, palaeo-ocean modelling and process-based analysis of modern depositional systems. This approach was applied to the Miocene–Modern Baram Delta Province (BDP), which is one of several peripheral basins around the South China Sea (SCS). Here, the ancient and modern systems are intimately linked through close similarities in climate (humid-tropical), tectonic setting (active margin) and sedimentary environments. The main focus was on shoreline environments, which comprise two main groups: (1) mixed-process, wave-dominated, fluvial- and tide-influenced shelf to shelf-edge deltas/shorelines, and (2) coastal embayments with similar mixed-process bayhead deltas, shorelines and estuaries. The principal controls on ancient stratigraphic preservation and architecture along this active tectonic margin were (1) drainage basin switching, (2) high rates of sedimentation and accommodation space, and (3) a coastal-deltaic plain with multiple fluvial entry points. The controls on tidal processes and preservation of tidal deposits, including ancient mangroves, are investigated for the Oligocene–Miocene around the SCS. Palaeotidal modelling results indicate that a regional-scale decrease in tidal energy during the Oligocene to present-day was a major control on coastal geomorphology, sediment dispersal, deposition, mangrove habitat and organic carbon (OC) burial during this period. Lithospheric storage of organic carbon (OC) in peripheral SCS basins during this period potentially exceeded 4000 Gt; this is equivalent to 2000 ppm of atmospheric CO2.
Damping of GRR instability by direct URCA reactions

description: The role of direct URCA reactions in damping of the gravitational radiation driven instability is discussed. The temperature at which bulk viscosity suppresses completely this instability is calculated. The results are obtained analytically using recent calculations performed in the case of bulk viscosity due to the modified URCA processes (Lindblom 1995; Yoshida & Eriguchi 1995). The bulk viscosity caused by direct URCA reactions is found to reduce significantly the region of temperatures and rotation frequencies where a neutron star is subject to GRR instability.

description: This paper introduces the geometric foundations for the study of the $s$-permutahedron and the $s$-associahedron, two objects that encode the underlying geometric structure of the $s$-weak order and the $s$-Tamari lattice. We introduce the $s$-permutahedron as the complex of pure intervals of the $s$-weak order, present enumerative results about its number of faces, and prove that it is a combinatorial complex. This leads, in particular, to an explicit combinatorial description of the intersection of two faces. We also introduce the $s$-associahedron as the complex of pure $s$-Tamari intervals of the $s$-Tamari lattice, show some enumerative results, and prove that it is isomorphic to a well chosen $ν$-associahedron. Finally, we present three polytopality conjectures, evidence supporting them, and some hints about potential generalizations to other finite Coxeter groups.

Heterogeneously coupled maps. From high to low dimensional systems through ergodic theory
Creators: name: Tanzi, Matteo
Publisher: name: Imperial College London
Year: 2017

description: In this thesis we study ergodic theoretical properties of high-dimensional systems coupled on graphs. The local dynamics at each node is hyperbolic and coupled with other nodes according to the edges of the graph. We focus our attention on the case of graphs with heterogeneous degrees meaning that most of the nodes make a small number of interactions, while a few hub nodes have very high degree. For such high-dimensional systems there is a regime of the interaction strength for which the coupling is small for poorly connected systems, and large for the hub nodes. In particular, global hyperbolicity might be lost. We show that, under certain hypotheses, the dynamics of hub nodes can be very well approximated by a low-dimensional system for exponentially long time in the size of the network and that the system exhibit hyperbolic behaviour in this time window. Even if this describes only a long transient, we argue that this is the behaviour that one expects to observe in experiments. Such a description allows us to establish the emergence of macroscopic behaviour such as coherence of dynamics among hubs of the same connectivity layer (i.e. with the same number of connections). The HCM we study provide a new paradigm to explain why and how the dynamics of a network dynamical system can change across layers.
Light matter interaction in mesoscopic systems
Creators: name: Armata, Federico
Publisher: name: Imperial College London
Year: 2017

description: The study of light-matter interaction has led to many fundamental discoveries as well as to the development of new technology. In this thesis, we investigate the interaction between light and matter in different mesoscopic systems such us Fabry-Perot cavities with fixed and/or moving mirrors (optomechanical cavities) and superconducting circuits. In the context of optomechanical cavities, we isolate genuine quantum contributions of the interaction between an optical field and a mechanical mirror and study how to probe nonlinearities of the mechanical motion. We also investigate dynamical corrections, arising from an initial non-equilibrium configuration of the system, to the Casimir energy induced by the interaction between a quantum multimode field and the quantum fluctuations of the movable mirror. In a cavity scenario, we further consider such kind of dynamical corrections for the Casimir-Polder force between an excited atom and a perfectly conducting mirror, finding new features that can allow for an easier way to single-out the dynamical Casimir-Polder effect. In the context of superconducting circuits, we explore the light-matter interaction between microwave fields and artificial atoms in the ultrastrong coupling regime, where the system displays a high degree of entanglement. We show how to extract these (otherwise inaccessible) quantum correlations, and how such correlations can potentially be exploited as a resource for entanglement-based applications. In all these investigations we provide feasible experimental scenarios where such new effects can be probed.
Laser synthesis for strong field physics
Creators: name: Arnold, Martin Oliver
Publisher: name: Imperial College London
Year: 2017

description: The work of this thesis involves temporal and spatial synthesis of the laser beam for use in strong field applications, such as high harmonic generation. The results include simulations of the electron trajectories with a temporally synthesised electric field, particularly the sub cycle laser field. The synthesis is produced by mixing of single colour fields and varying the phase between the two pulses. This showed an extension of the high harmonic cutoff from the typical 3.17UP to 5.05UP, and is due to the longer time the electron spends in the continuum due to the subcycle temporal synthesis. A temporal synthesis of the pulse envelope was carried out using a birefringent plate and cube polariser. A pair of birefringent wedges at 45 degrees relative to the laser polarisation was used to vary the phase between the two generated pulses. The spectrum of the laser is shown to shift depending on the relative phase between the two pulses. Subsequent simulations of this effect is presented and compared to the experimental results of which there is agreement in the periodicity of the spectral shift and magnitude. High harmonic generation was also measured and studied to show the harmonic frequency shifting proportionally to the laser depending on the harmonic order. Spatial synthesis of the laser field was studied and also used for generation of high harmonics. A pair of concentric phase plates was used to generate a spatial flat top intensity profile in the focus of the laser beam. The flat top was found to extend plus/minus 1mm either side of the focus of 100 um. The beam waist at the focus increased from 45 um to 100 um during this synthesis, causing a drop in intensity such that harmonics were very hard to achieve.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We present a new algorithm for inverting poorly resolved gravitational lens systems using the maximum entropy method (MEM). We test the method with simulations and then apply it to an 8 GHz VLA map of the radio ring lens MG1654+134. We model the lens as a singular isothermal sphere embedded in an external shear field and find the critical radius of the lens is $b=0\parcs9820$, the dimensionless shear is $γ=0.0771$, and the position angle of the shear is $θ=100\pdeg8$. These results are consistent with the results obtained by Kochanek (1995) using a complementary inversion algorithm based on Clean.

description: Machine learning algorithms provide a new perspective on the study of physical phenomena. In this paper, we explore the nature of quantum phase transitions using multi-color convolutional neural-network (CNN) in combination with quantum Monte Carlo simulations. We propose a method that compresses $d+1$ dimensional space-time configurations to a manageable size and then use them as the input for a CNN. We test our approach on two models and show that both continuous and discontinuous quantum phase transitions can be well detected and characterized. Moreover we show that intermediate phases, which were not trained, can also be identified using our approach.

description: Context: Elevated atmospheric CO2 (e[CO2]) and nitrogen (N) fertilisation stimulate biomass and yield of crops. However, their interactions depend on crop growth stages and may affect water use dynamics. Aims and methods: This study investigated the interactive effects of two N rates, 0 and 100 kg N ha-1, and two CO2 concentrations, ambient (a[CO2], 400 μmol mol-1) and e[CO2] (550 μmol mol-1), on biomass, yield and water use of two wheat cultivars, Wyalkatchem (N-use efficient) and Yitpi (local), using a free air CO2 enrichment facility. Key results: Elevated [CO2] stimulated leaf area (10%, P = 0.003) and aboveground biomass (11%, P = 0.03). In addition, e[CO2] reduced stomatal conductance (25%, P < 0.001) and increased net assimilation rates (12%, P < 0.001), resulting in greater (40%, P < 0.001) intrinsic water use efficiency. During early growth stages, e[CO2] resulted in higher water use than a[CO2]; however, this difference disappeared later in the season, resulting in similar cumulative water use under both CO2 concentrations. Supplemental N stimulated grain yield of Yitpi by 14% while decreasing that of Wyalkatchem by 7% (N × cultivar, P = 0.063). With supplemental N, Yitpi maintained greater post-anthesis leaf N, chlorophyll content, canopy cover and net assimilation rate than Wyalkatchem. Conclusions: During early growth stages, the e[CO2]-induced stimulation of leaf-level water use efficiency was offset by greater biomass, resulting in higher water use. By the end of the season, similar cumulative water use under both CO2 concentrations indicates the dominating effect of the prevailing seasonal conditions in the study area. Observed yield responses of the studied cultivars to supplemental N were associated with their ability to maintain post-anthesis photosynthetic capabilities. Implications: Our findings suggest that N-use efficiency traits and responsiveness need to be considered independently to optimise benefits from the 'CO2 fertilisation effect' through breeding.
Tests of the Standard Model in Neutron Beta Decay with Polarized Neutron and Electron and Unpolarized Proton

description: We analyse the electron--energy and angular distribution of the neutron beta decay with polarized neutron and electron and unpolarized proton, calculated in Phys. Rev. C 95, 055502 (2017) within the Standard Model (SM), by taking into account the contributions of interactions beyond the SM. After the absorption of vector and axial vector contributions by the axial coupling constant and Cabibbo-Kobayashi-Maskawa (CKM) matrix element (Bhattacharya et al., Phys. Rev. D 85, 054512 (2012) and so on) these are the contributions of scalar and tensor interactions only. The neutron lifetime, correlation coefficients and their averaged values, and asymmetries of the neutron beta decay with polarized neutron and electron are adapted to the analysis of experimental data on searches of contributions of interactions beyond the SM. Using the obtained results we propose some estimates of the values of the scalar and tensor coupling constants of interactions beyond the SM. We use the estimate of the Fierz interference term "b_F = - 0.0028 +/- 0.0026" by Hardy and Towner (Phys. Rev. C 91, 025501 (2015)), the neutron lifetime "tau_n = 880.2(1.0)s"(Particle Data Group, Chin. Phys. C 40, 100001 (2016)) and the experimental data "N_{\exp} = 0.067 +/- 0.011_{\rm stat.} +/- 0.004_{\rm syst.}" for the averaged value of the correlation coefficient of the neutron-electron spin-spin correlations, measured by Kozela et al. (Phys. Ref. C 85, 045501 (2012)). The contributions of G-odd correlations are calculated and found at the level of 10^{-5} in agreement with the results obtained by Gardner and Plaster (Phys. Rev. C 87, 065504 (2013)).

description: For the simultaneous estimation of metformin and pioglitazone from pharmaceutical dosage forms, a quick, selective, rapid, accurate, and cost-effective reverse phase HPLC method has been developed. The method was carried out on a phenomenex C18 (25 cm x 4.6 mm i.d., 5 µ) column with a mobile phase consisting of acetonitrile: phosphate buffer (adjusted to pH 5.0 using orthophosphoric acid) (50:50 v/v) at a flow rate of 1. ml/min. The detection wavelength was 258 nm.As an internal control, etoricoxib was used. Paracetamol, aceclofenac, and etoricoxib had retention times of 4.75, 6.44, and 8.83 minutes, respectively.In terms of accuracy, precision, linearity, limit of detection, limit of quantitation and solution stability, the established method was validated. The suggested method can be used to calculate the dosage forms of these drugs in combination dosage forms. The current RP-HPLC system can be used to check the consistency of raw materials, formulations, and dissolution tests.
