description: A series of new 5-amino-7-bromoquinolin-8-ol sulfonate derivatives 5(a-j) were synthesized from 8-hydroxyquinoline through multi-step process with high yields using mild, efficient and conventional methods. Chemoselectivity was observed during the transformation of 5-amino-7-bromoquinolin-8-ol to 5-amino-7-bromoquinolin-8-ol sulfonate with various sulfonylchlorides exclusively to afford sulfonate derivatives. Also, the products were investigated for their in vitro antimicrobial activities and compared with the standard drugs. Among all the synthesized compounds 5-Amino-7-bromoquinolin-8-yl biphenyl-4-sulfonate (5b) and 5-Amino-7-bromoquinolin-8-yl 2-hydroxy-5-nitrobenzenesulfonate (5g) have showed potent antibacterial activity, whereas 5-Amino-7-bromoquinolin-8-yl biphenyl-4-sulfonate (5b) and 5-Amino-7-bromoquinolin-8-yl 2-hydroxy-5-nitrobenzenesulfonate (5g) possessed potent antifungal activities among all the tested pathogens.

Magnetohydrodynamic Turbulence in Accretion Disks

description: Recent work on the structure of magnetic fields in a turbulent medium gives predictions for the properties of the magnetic flux tubes as a function of the Mach number and scale of the turbulence, and the resistivity and viscosity of the fluid. Here I discuss the implications of this work for accretion disks. I show that although accretion disk flux tubes are usually almost completely evacuated, they are nevertheless less buoyant than previous estimates have suggested. I also note that vertical magnetic flux tends to be ejected from the outer edge of accretion disks, so evidence for continued magnetic activity in such systems should be interpreted as supporting the existence of dynamo activity.

Ungrounded haptic-feedback for hand-held surgical robots
Creators: name: Payne, Christopher
Publisher: name: Imperial College London
Year: 2015

description: Surgical robotic technology has evolved over the last few decades: from autonomous systems, to master-slave and cooperatively-controlled assistive robots. Whilst these various approaches have proven to be technically successful, clinical adoption of robotic technology remains moderate, largely as a result of the financial cost of such technology. An alternative approach that has been recently explored is the integration of mechatronic technology in to surgical devices that are held by the hands of the surgeon and are unattached to a grounding frame. These ungrounded hand-held devices exploit the existing dexterity of the surgeon’s hand that allows them to be simpler, physically compact, lower cost, more easily integrated in to the surgical workflow and with fewer barriers to clinical translation. This thesis explores the use of mechatronic technology in ungrounded, hand-held surgical tools for the purpose of augmenting a surgeon’s haptic perception. During microsurgery in particular, the tool-tissue manipulation forces are often so low that they cannot be perceived by the operating surgeon. This thesis initially proposes a hand-held device that can amplify these sub-threshold forces to magnitudes that can be perceived by human subjects. The mechatronic force amplification concept is further evolved for use in microsurgical forceps designs. In this case, haptic perception is diminished by the elastic spring return of the forceps which is significantly greater in magnitude than the micro-scale manipulation forces. Having investigated the force amplification concept, vibrotactile-based feedback of predefined force-thresholds is investigated. The concept is studied through the clinical exemplar of microneurosurgery: a device is proposed which can inform the operating surgeon if they are exerting excessive force based on a force threshold at which iatrogenic injury of neurovascular tissue is known to occur. Finally, an ungrounded force-feedback strategy is investigated for use with a hand-held device that incorporates position-based active constraints of the tool tip.

description: Interactions between galaxies are common and are an important factor in determining their physical properties such as position along the Hubble sequence and star-formation rate. There are many possible galaxy interaction mechanisms, including merging, ram-pressure stripping, gas compression, gravitational interaction and cluster tides. The relative importance of these mechanisms is often not clear, as their strength depends on poorly known parameters such as the density, extent and nature of the massive dark halos that surround galaxies. A nearby example of a galaxy interaction where the mechanism is controversial is that between our own Galaxy and two of its neighbours -- the Large and Small Magellanic Clouds. Here we present the first results of a new HI survey which provides a spectacular view of this interaction. In addition to the previously known Magellanic Stream, which trails 100 degrees behind the Clouds, the new data reveal a counter-stream which lies in the opposite direction and leads the motion of the Clouds. This result supports the gravitational model in which leading and trailing streams are tidally torn from the body of the Magellanic Clouds.

description: The latest Lyman-$α$ forest data severely constrain the conventional warm dark matter solution to small-scale issues in the cold dark matter paradigm. It has been also reported that unconstrained astrophysical processes may address the issues. In response to this situation, we revisit the decaying dark matter solution to the issues, discussing possible signatures to discriminate decaying dark matter from astrophysical processes as a solution to small-scale issues. We consider an axinolike particle (ALPino) decaying into an axionlike particle (ALP) and gravitino with the lifetime around the age of the Universe. The ALPino mass is sub-PeV and slightly ($Δm/m\sim 10^{-4}$) larger than the gravitino mass, and thus the dark matter abundance does not alter virtually after the ALPino decays. On the other hand, the gravitino produced from the ALPino decay obtains a kick velocity of $\sim 30 \,{\rm km / s}$, which is sufficiently larger than a circular velocity of dwarf galaxies to impact their dark matter distributions. The Lyman-$α$ forest constraints are relieved since only a small fraction ($\sim10$%) of dark matter experiences the decay at that time. Decaying dark matter is thus promoted to a viable solution to small-scale issues. The ALPino relic abundance is determined predominantly by the decay of the lightest ordinary supersymmetric particle. The monochromatic ALP emission from the ALPino decay is converted to $\sim 50 \,{\rm GeV}$ photon under the Galactic magnetic field. The morphology of the gamma-ray flux shows a distinctive feature of the model when compared to decaying dark matter that directly decays into photons. Once detected, such distinctive signals discriminate the decaying dark matter solution to small-scale issues from unconstrained astrophysical processes.

description: Determinations of the \he3 concentrations in Galactic matter serve to impose interesting and important constraints both on cosmological models and on models of Galactic chemical evolution. At present, observations of \he3 in the solar system and in the interstellar medium today suggest that the \he3 abundance has not increased significantly over the history of the Galaxy, while theoretical models of Galactic chemical evolution (utilizing current nucleosynthesis yields from stellar evolution and supernova models) predict a rather substantial increase in \he3. We consider the possibility that the solar \he3 abundance may have been affected by stellar processing in the solar neighborhood prior to the formation of the solar system. Such a discrepancy between solar abundances and average galactic abundances by as much as a factor of two, may be evidenced by several isotopic anomalies. Local destruction of \he3 by a similar amount could serve to help to reconcile the expected increase in the \he3 abundance predicted by models of galactic chemical evolution. We find however, that the production of heavier elements, such as oxygen, places a strong constraint on the degree of \he3 destruction. We also explore the implications of both alternative models of Galactic chemical evolution and the stellar yields for \he3 in low mass stars, which can explain the history of the \he3 concentration in the Galaxy.

The role of myosin regulatory light chain phosphorylation in cardiac health and disease
Creators: name: Toepfer, Christopher
Publisher: name: Imperial College London
Year: 2015

description: In this thesis we examined the effect of myosin associated regulatory light chain (RLC) phosphorylation level on cardiac muscle, ensembles and single molecules. We measured the ability of RLC phosphorylation change in muscle to alter force, power and unloaded shortening. The ATPase rate of full length cardiac myosin was determined with a novel protocol using gelsolin capped actin, which allowed novel measurements of myosin ATPase with full length (filamentous) myosin in low ionic strength. Actin gliding assays determined the effects of RLC phosphorylation level on actin gliding velocities under high and negligible load. The lifetime of strongly bound actomyosin states and the displacement of single myosin molecules were examined using an optical trapping three bead assay. A quantitative Phos-tag SDS-PAGE protocol was used to assess RLC phosphorylation level in inherited (mutation) and acquired (infarct and heart failure) human and rat diseases. Cardiac disorders in human and rat left ventricular myocardium correlated with increased RLC phosphorylation. RLC phosphorylation alters the ability of muscle to produce force, power and maximal unloaded shortening. Increased RLC phosphorylation accelerated the ATPase rate of cardiac myosin; reduced the lifetime of strongly bound actomyosin states and increased the displacement of actin by myosin. This data correlated with an increased ability of myosin with phosphorylated RLCs to translocate actin, under high and low load in the actin gliding assay. Cardiac myosin with raised RLC phosphorylation can produce more force and power during shortening due to changes in ATPase cycle, lifetime of the strongly bound states and power stroke size under load. Therefore myosin can perform work on actin faster and produce a longer actin displacement with each cycle. Thus proving that RLC phosphorylation level alteration impacts systolic myocardial performance in human health and disease by altering both myosin mechanics and kinetics.

description: The second flight of the Medium Scale Anisotropy Measurement (MSAM1-94) observed the same field as the first flight (MSAM1-92) to confirm our earlier measurement of cosmic microwave background radiation (CMBR) anisotropy. This instrument chops a 30\arcmin\ beam in a 3 position pattern with a throw of $\pm40\arcmin$, and simultaneously measures single and double differenced sky signals. We observe in four spectral channels centered at 5.6, 9.0, 16.5, and 22.5~\icm, providing sensitivity to the peak of the CMBR and to thermal emission from interstellar dust. The dust component correlates well with the \IRAS\ 100~\micron\ map. The CMBR observations in our double difference channel correlate well with the earlier observations, but the single difference channel shows some discrepancies. We obtain a detection of fluctuations in the MSAM1-94 dataset that match CMBR in our spectral bands of $ΔT/T = 1.9^{+1.3}_{-0.7}\times 10^{-5}$ (90\% confidence interval, including calibration uncertainty) for total rms Gaussian fluctuations with correlation angle 0\fdg3, using the double difference demodulation.

description: The effect of a local instantaneous quantum dynamical process (QDP), either unitary or non-unitary, on the quantum state transfer through a unitary Hamiltonian evolution is investigated for both integrable and non-integrable dynamics. There are interference effects of the quantum state propagation and the QDP signal propagation. The state transfer fidelity is small for further sites, from the site where the information is coded, indicating a finite speed for the propagation of the quantum correlation. There is a small change in the state transfer fidelity for the case of non- unitary QDP intervening the background unitary dynamics. In the case of unitary QDP, the change is more pronounced, with a substantial increase in the fidelity for appropriate sites and times. For the non-integrable case, viz. a kicked Harper model, the state transfer fidelity is quite large for further sites for short times, indicating a finite speed for the propagation of the quantum correlation cannot be defined.

description: Recent advances in nanotechnology have enabled researchers to manipulate small collections of quantum mechanical objects with unprecedented accuracy. In semiconductor quantum dot qubits, this manipulation requires controlling the dot orbital energies, tunnel couplings, and the electron occupations. These properties all depend on the voltages placed on the metallic electrodes that define the device, whose positions are fixed once the device is fabricated. While there has been much success with small numbers of dots, as the number of dots grows, it will be increasingly useful to control these systems with as few electrode voltage changes as possible. Here, we introduce a protocol, which we call the Compressed Optimization of Device Architectures (CODA), in order to both efficiently identify sparse sets of voltage changes that control quantum systems, and to introduce a metric which can be used to compare device designs. As an example of the former, we apply this method to simulated devices with up to 100 quantum dots and show that CODA automatically tunes devices more efficiently than other common nonlinear optimizers. To demonstrate the latter, we determine the optimal lateral scale for a triple quantum dot, yielding a simulated device that can be tuned with small voltage changes on a limited number of electrodes.

description: The strength and spectrum of the extragalactic magnetic field are still unknown. Its measurement would help answer the question of whether galactic fields are purely a primordial relic or were dynamically enhanced from a much smaller cosmological seed field. In this letter, we show that the composition, spectrum, and directional distribution of extragalactic ultrahigh energy cosmic rays with energies above $\simeq 10^{18}\ev$ can probe the large scale component of the extragalactic magnetic field below the present observational upper limit of $10^{-9}$ Gauss. Cosmic ray detectors under construction or currently in the proposal stage should be able to test the existence of the extragalactic magnetic fields on scales of a few to tens of Mpc and strengths in the range $\simeq 10^{-10} - 10^{-9}$ Gauss.

description: Background: The presence of foreign body in musculoskeletal tissue is a major concern for the patient and treating doctor with regard to its varied presentations and appropriate management. Both metallic and nonmetallic foreign bodies have been studied extensively with special emphasis on its detection by various imaging modalities and unusual presentations of retained foreign ones. An early detection and retrieval is the mainstay of management, leading to an uneventful recovery. It also prevents subsequent complications of neglected, missed, or retained foreign bodies. The increased indulgence in recreational and industrial activities in recent times has increased prevalence and scope of penetrating injuries with various objects. Detailed data regarding patterns and presentations of various foreign body retention of musculoskeletal tissue, both acute and chronic, thus are helpful to format an anticipatory or preventive workup. Furthermore, the knowledge of the types of common foreign bodies in a region helps in drafting investigative and ameliorative public health strategies.Materials and Methods: The current study is a retrospective account of pattern and presentation of non firearm foreign bodies managed in a tertiary care teaching hospital within a defined period. Besides it, patient characteristics and relevant details of trauma and associated findings were listed with at least 4-month follow-up.Results: Male sex, upper extremity, and left side of body were commonly involved. There was predilection for acral parts such as hand and feet. Agricultural and industrial setup was the common scenario associated with the injuries, and vegetative foreign bodies were mostly found followed by metallic ones among others.Conclusion: The study highlights various aspects of acute or chronic foreign body retention in clinical settings and is helpful to know type, pattern and presentation in a geographical region.

Simplicial Activity Driven Model

description: Many complex systems find a convenient representation in terms of networks: structures made by pairwise interactions (links) of elements (nodes). For many biological and social systems, elementary interactions involve however more than two elements, and simplicial complexes are more adequate to describe such phenomena. Moreover, these interactions often change over time. Here, we propose a framework to model such an evolution: the Simplicial Activity Driven (SAD) model, in which the building block is a simplex of nodes representing a multi-agent interaction. We show analytically and numerically that the use of simplicial structures leads to crucial differences in the outcome of paradigmatic processes modelling disease propagation or social contagion, with respect to the activity-driven (AD) model, a paradigmatic temporal network model involving only binary interactions. In particular, fluctuations in the number of nodes involved in the interactions can affect the outcome of models of simple contagion processes, contrarily to what happens in the AD model. Moreover, social contagion models such as cascading processes present a much richer phenomenology and can become extremely slow when occurring on evolving simplicial complexes.

description: We study a dynamic boundary, e.g. a mobile impurity, coupled to N independent Tomonaga-Luttinger liquids (TLLs) each with interaction parameter K. We demonstrate that for N>2 there is a quantum phase transition at K>1/2, where the TLL phases lock together at the particle position, resulting in a non-zero transconductance equal to e^2/Nh. The transition line terminates for strong coupling at K=1- 1/N, consistent with results at large N. Another type of a dynamic boundary is a superconducting (or Bose-Einstein condensate) grain coupled to N>2 TLLs, here the transition signals also the onset of a relevant Josephson coupling.

description: Wearable robots (WRs) are increasingly moving out of the labs toward real-world applications. In order for WRs to be effectively and widely adopted by end-users, a common benchmarking framework needs to be established. In this article, we outline the perspectives that in our opinion are the main determinants of this endeavor, and exemplify the complex landscape into three areas. The first perspective is related to quantifying the technical performance of the device and the physical impact of the device on the user. The second one refers to the understanding of the user's perceptual, emotional, and cognitive experience of (and with) the technology. The third one proposes a strategic path for a global benchmarking methodology, composed by reproducible experimental procedures representing real-life conditions. We hope that this paper can enable developers, researchers, clinicians and end-users to efficiently identify the most promising directions for validating their technology and drive future research efforts in the short and medium term.

For most subsamples of clusters considered, their positions on the sky appear to be anti-correlated with respect to the distribution of HI column densities. The statistical significance of these observed anti-correlations is a function of both richness and distance class, with the more distant and/or richest systems having the highest significance (~3 sigma). The lower richness, nearby clusters appear to be randomly distributed compared to the observed Galactic HI column density.

Adaptive control and monitoring of a C.N.C. lathe using feed-force and machine-vision
Creators: name: Daneshmend, Laeeque Khan
Publisher: name: Imperial College London
Year: 1985

description: This thesis examines some aspects of adaptive control and machine monitoring for Computer Numerically Controlled (CNC) lathes. The design and implementation of a distributed, axls-partioned, multi-microprocessor based CNC system is described in Chapter 2. This CNC system, retrofitted to a lathe, has been developed specifically as a test-bed for research into advanced control and machine monitoring techniques. Chapter 3 is a survey of adaptive control and monitoring techniques for machine tools in general. The next three chapters are devoted to the parameter adaptive control of feed force. Chapter 4 presents some basic analysis of the position and force control loops on the lathe. Chapter 5 looks at parameter adaptive control theory in general, and at a design technique for model reference adaptive control of discrete-time single-input/single-output plants in particular. This design technique is applied to the feed force regulation problem, using feedrate as the control input. Results of applying several feed force regulation algorithms, derived from the design technique of Chapter 5. are presented in Chapter 6. The use of machine vision for flank wear measurement of turning tools Is investigated in Chapter 7. Experimental results and Image processing algorithms are presented.

description: Molecular recognition of dicarboxylates by a dinuclear zinc(II) complex of 2,2ʹ-binaphthalene bearing di(2-pyridyl)aminomethyl groups at 8- and 8ʹ-positions ([Zn2L]4+) by UV-vis and fluorescence spectral titrations in an aqueous solvent was investigated. In a series of α,ω-dicarboxylate, receptor [Zn2L]4+ showed the highest binding affinity for succinate and UV-vis and fluorescence changes were also largest upon the addition of this guest. In a series of phthalate derivatives, phthalate was strongly bound by [Zn2L]4+. The characteristic UV-vis and fluorescence changes strongly depend on the dihedral angle of two naphthyl groups of the complex [Zn2L]4+· dicarboxylate estimated by spectral titrations and DFT calculations.

description: We present new X-ray, radio, and optical data for the unusual galaxy/cluster system J2310-437. Our results confirm the presence of an active nucleus, and suggest an interpretation as an anomalous BL Lac object of bulk relativistic Doppler factor < 2, with an optically deficient radio-to-X-ray spectrum. The radio, optical, and soft X-ray flux densities could lie along a single power-law function, lacking the curvature typical of BL Lac objects. Compared with other known sources that may have comparable multifrequency spectra, J2310-437 is the most extreme. Its low isotropic optical/UV radiation is consistent with the intensity of external photons governing the electron spectral break through Compton cooling; in this source the external photon density would be too low to produce a spectral break below the X-ray.

Assessment of HVDC technologies for an offshore MTDC grid
Creators: name: Sheridan, Caitríona Evelyn
Publisher: name: Imperial College London
Year: 2015

description: This thesis examines various HVDC converter technologies that could be used in offshore Multi-Terminal DC (MTDC) grids. MTDC grids rely on AC/DC converters to interface with AC systems and also for control services. Two AC/DC topologies were compared, the half-bridge Modular Multi-level Converter (MMC) and the Alternate Arm Converter (AAC). As new DC system voltages emerge the DC/DC converter could be an enabling technology for interconnection and future MTDC networks. As yet there is no consensus on DC/DC converter topology and a critical comparison of several potential designs was conducted. An MMC based DC/DC converter had distinct advantages compared with other designs. Several average value converter models of the converters were developed to allow efficient simulation of MTDC networks, while maintaining a high level of accuracy of the converter characteristics. These models were verified with full switching models for steady state and fault conditions. Two o shore MTDC networks were studied; a four-terminal network, and a MTDC network. The four-terminal network used a normally open point to connect two existing point-to-point links, allowing reconfiguration in the event of a DC fault. The MTDC network uses a DC/DC converter to interconnect a bipole HVDC link with the previously studied four-terminal network. Several simulation studies show how new converters can improve the operation of a MTDC and provide additional capabilities such as DC fault blocking.

Robust detection and localisation of cars in airborne imagery
Creators: name: ElMikaty, Mohamed
Publisher: name: Imperial College London
Year: 2016

description: With the ever-increasing demand in the analysis and understanding of aerial images, this work is focused on the use of implicit models for the detection and localisation of small targets in static airborne imagery of typical urban scenes with associated ground sampling distance of few centimetres. These scenes are characterised by the existence of complex structures and heavy clutter. More specifically, it focuses on the detection of non-occluded cars as it has many useful applications in security, surveillance, remote sensing and other domains. This is a tremendously-challenging problem because of the huge inter-class similarity among car and other non-car targets in urban scenes. Nevertheless, it will be demonstrated that high precision rates can be achieved using robust ensembles of image descriptors alongside linear classification techniques, e.g., linear Support Vector Machines. The original contributions of this work include: i) novel methods to reduce search areas by evaluating the likeliness of detection windows to contain targets, (ii) accurate methods to estimate the dominant orientation of detection windows, (iii) robust ensembles of image descriptors of low dimensionality relative to the state of the art that depict the distributions of gradients, texture, colours, spectral information and the second-order statistics of each and (iv) a new method to extract regions that are placed around roads using a Gaussian Mixture Model classifier. The performance of the proposed frameworks was evaluated against two benchmark datasets of static images, namely, the Vaihingen and the Overhead Imagery Research datasets. Results show that the proposed frameworks are superior to and outperform the state of the art.

description: This paper proposed an engineered mesoporous silica-coated Fe3O4 nanoparticle, PVPMSFe, prepared by a sol-gel/surface-protected etching mechanism as an MRI T2 contrast agent. To this end, the structural characterization of the nanocomposite was performed by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) method, VSM, thermogravimetric analysis (TGA), TEM, FESEM, and energy-dispersive X-ray scanning electron microscopy (EDS). The findings show that the synthesized nanocomposite has a mesoporous structure with an average particle size of 11.8 nm and excellent magnetization properties. The biocompatibility of PVPMSFe was investigated by MTT assay and hemolysis assay of red blood cells and the results indicate that PVPMSFe has favorable biocompatibility. Besides, the effect of PVPMSFe was assessed with MRI relaxivity measurement (T2 signal). Regarding the in vitro MRI relaxivity measurements outputs (r2=144.4), PVPMSFe can attenuate the T2 signal of MRI, perfectly which makes it an efficient T2 contrast agent.

description: Motivated by recent studies of the one-bubble inflationary scenario, simple open cold dark matter models are tested for consistency with cosmological observations. The initial perturbation spectrum is derived by solving for the evolution of fluctuations in an open inflationary stage. A likelihood analysis is performed for the Cosmic Microwave Background anisotropies using the two-year COBE DMR data and considering models based on both the Bunch-Davies and conformal vacua. Having normalized the perturbation spectrum to fit the COBE data, we reconsider the validity of the open model from the view point of cosmic structure formation. Open models may be severely constrained by the COBE likelihood analysis. In particular, small values of $Ω_0$ are ruled out in the Bunch-Davies case: we find that $Ω_0\ge 0.34$ at 95\% confidence for this model.

A Deep Multicolor Survey V: The M Dwarf Luminosity Function

description: We present a study of M dwarfs discovered in a large area, multicolor survey. We employ a combination of morphological and color criteria to select M dwarfs to a limiting magnitude in V of 22, the deepest such ground-based survey for M dwarfs to date. We solve for the vertical disk stellar density law and use the resulting parameters to derive the M dwarf luminosity and mass functions from this sample. We find the stellar luminosity function peaks at M_V = 12 and declines thereafter. Our derived mass function for stars with M < 0.6 M_sun is inconsistent with a Salpeter function at the 3 sigma level; instead, we find the mass function is relatively flat for 0.6 M_sun > M > 0.1 M_sun.

description: We present a next-to-leading order accurate simulation of t-channel single-top plus jet production matched to parton showers via the POWHEG method. The calculation underlying the simulation is enhanced with a process-specific implementation of the multi-scale improved NLO (MINLO) method, such that it gives physical predictions all through phase space, including regions where the jet additional to the t-channel single-top process is unresolved. We further describe a tuning procedure for the MINLO Sudakov form factor, fitting the coefficient of the first subleading term in its exponent using an artificial neural-network. The latter tuning, implemented as a straightforward event-by-event reweighting, renders the MINLO simulation NLO accurate for t-channel single-top observables, in addition to those of the analogous single-top plus jet process.
