description: We analyze the role of indirect quantum measurements in work extraction from quantum systems in nonequilibrium states. In particular, we focus on the work that can be obtained by exploiting the correlations shared between the system of interest and an additional ancilla, where measurement backaction introduces a nontrivial thermodynamic tradeoff. We present optimal state-dependent protocols for extracting work from both classical and quantum correlations, the latter being measured by discord. We show that, while the work content of classical correlations can be fully extracted by performing local operations on the system of interest, the amount of work related to quantum discord requires a specific driving protocol that includes interaction between system and ancilla.

description: Defect centers in diamond are promising building blocks for quantum networks thanks to a long-lived spin state and bright spin-photon interface. However, their low fraction of emission into a desired optical mode limits the entangling success probability. The key to overcoming this is through Purcell enhancement of the emission. Open Fabry-Perot cavities with an embedded diamond membrane allow for such enhancement while retaining good emitter properties. To guide the focus for design improvements it is essential to understand the influence of different types of losses and geometry choices. In particular, in the design of these cavities a high Purcell factor has to be weighed against cavity stability and efficient outcoupling. To be able to make these trade-offs we develop analytic descriptions of such hybrid diamond-and-air cavities as an extension to previous numeric methods. The insights provided by this analysis yield an effective tool to find the optimal design parameters for a diamond-air cavity.

description: The spin-induced quadrupole moment of a rapidly rotating star changes the orbital dynamics in a binary system, giving rise to advance (or regression) of periastron and precession of the orbital plane. We show that these effects are important in the recently discovered radio pulsar/main sequence star binary system PSR J0045$-$7319, and can reliably account for the observed peculiar timing residuals. Precise measurements of the apsidal motion and orbital plane precession can yield valuable information on the internal structure and rotation of the star. The detection of orbital precession implies that the spin of the companion star is not aligned with the orbital angular momentum, and suggests that the supernova gave the pulsar a kick out of the original orbital plane. Tidal excitation of g-mode oscillations in the PSR J0045$-$7319 system induces an orbital period change of order $|ΔP_{\rm orb}/P_{\rm orb}|\sim 10^{-6}$ at each periastron passage, but the secular trend depends on the radiative damping time of the g-modes. We also discuss the spin-orbit coupling effects for the accreting X-ray pulsars and the other known radio pulsar/main sequence binary, PSR B1259$-$63.

New Field, Old Practices: Promises and Challenges of Public History
Creators: name: Cauvin, Thomas
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

Although public history is becoming increasingly international, the field remains difficult to define and subject to some criticism. Based on sometimes long-established public practices, public history displays new approaches to audiences, collaboration and authority in history production. This article provides an overview of public history, its various definitions and historiography, and discusses some of the main criticisms of the field. Public history is compared to a tree of knowledge whose parts (roots, trunk, branches and leaves) represent the many collaborative and interconnected stages in the field. Defining public history as a systemic process (tree) demonstrates the need for collaboration between the different actors – may they be trained historians or not – and aim to focus on the role they play in the overall process. The future of international public history will involve balancing practice-based approaches with more theoretical discussions on the role of trained historians, audiences and different uses of the past.

description: Designing functional materials requires a deep search through multidimensional spaces for system parameters that yield desirable material properties. For cases where conventional parameter sweeps or trial-and-error sampling are impractical, inverse methods that frame design as a constrained optimization problem present an attractive alternative. However, even efficient algorithms require time- and resource-intensive characterization of material properties many times during optimization, imposing a design bottleneck. Approaches that incorporate machine learning can help address this limitation and accelerate the discovery of materials with targeted properties. In this article, we review how to leverage machine learning to reduce dimensionality in order to effectively explore design space, accelerate property evaluation, and generate unconventional material structures with optimal properties. We also discuss promising future directions, including integration of machine learning into multiple stages of a design algorithm and interpretation of machine learning models to understand how design parameters relate to material properties.
Self-adaptive containers: a novel framework for building scalable QoS-aware software with low programmer overhead
Creators: name: Huang, Wei-Chih
Publisher: name: Imperial College London
Year: 2015

description: As the number of execution environments increases dramatically, ever-changing non-functional requirements often lead to the challenge of frequent code refactoring. Despite help of traditional software engineering techniques, adapting software to meet each execution environment and application context remains a non-trivial endeavour. Manually reimplementing software possibly takes months or years of programmer effort and requires high levels of expertise. Furthermore, to build software for different execution environments often results in either a small code base which cannot guarantee Quality of Service or a large manually-optimised code base which is difficult to maintain. This thesis presents a novel self-adaptive container framework which can dynamically adjust its resource usage in an effort to meet resource constraints and scalability requirements. Each container instance is associated with programmer-specified Service Level Objectives with respect to performance, reliability, and primary memory use. To prevent ambiguity among multiple Service Level Objectives, each of them is specified in the format of standard Web Service Level Agreement. This framework features tighter functionality specification than that of standard container frameworks, which enables greater scope for efficiency optimisations, including the exploitation of probabilistic data structures, out-of-core storage, parallelism, and cloud storage. These techniques are utilised in a low-cost way through the integration of third-party libraries, which also enable our framework to provide a wider class of Service Level Objectives. In addition, to reduce the time of learning how to use the framework, its interfaces are designed to be close to those of standardised libraries. The framework has been implemented in C++ and utilised in two case studies centred on explicit state-space exploration adopting a breadth-first search algorithm, and route planning adopting a Dijkstra’s shortest path algorithm. In order to illustrate the framework's viability and capability, various Service Level Objectives are assigned. Furthermore, the implementation of our framework is utilised to explore approximately 240 million states in the first case study and to find the shortest path of a graph representing the USA road network, containing approximately 24 million nodes and 58 million arcs. The experimental results show that the framework is capable of dynamically adjusting its resource usage according to assigned Service Level Objectives and dealing with large-scale data. At the same time, the programmer overhead is kept low in terms of the degree to which code is modified.

A study of the growth and hydrogen production of Cyanothece sp. ATCC 51142
Creators: name: Dechatiwongse, Pongsathorn
Publisher: name: Imperial College London
Year: 2015

description: Hydrogen (H2) has long been promoted as an ideal fuel, as it permits a completely clean combustion and has great potential to provide clean power needed for transport and electricity generation. The unicellular, nitrogen-fixing cyanobacterium Cyanothece sp. ATCC 51142 is a promising strain with a remarkable capability of producing large quantities of H2. Under anaerobic condition, the cyanobacterium carries out the biological fixation of atmospheric nitrogen (N2) into ammonia (NH3), concurrently producing H2 as by-product. The aim of this thesis was to improve our understanding of the growth and H2 production of Cyanothece sp. ATCC 51142 in order to develop a continuous and practical cyanobacterial H2 production process. In order to achieve effective H2 production, it is prerequisite to grow dense and healthy Cyanothece 51142 cultures. Favourable cyanobacterial growth conditions included a continuous illumination at 207 - 320 μmol m-2 s-1, temperature of 35 °C and nitrogen-replete (addition of nitrate salts) condition. The critical temperature, which induces photoinhibition upon the cyanobacterium, was found at 40 °C. In the case of H2 production, favourable conditions included a continuous illumination at low light intensities of 46 – 92 μmol m-2 s-1, temperature of 30 °C, nitrogen-fixing (sole presence of atmospheric N2) and photoheterotrophic (sole presence of organic glycerol substrate) growth condition. In order to effectively handle incompatible requirements between the cyanobacterial growth and its sequential H2 production, a novel two-stage chemostat photobioreactor (PBR) system was designed and developed, with an aim to improve H2 production yield as well as extend its production duration. The system has been operated non-stop for consecutive 31 days without any losses in its performance and subsequently demonstrated a remarkable improvement in H2 production, with more than 6.4 times higher yield than that of a single-stage batch system. With the continuous mode of operation, a continuous collection of produced biomass from the PBR is also permitted (more than 7.3 times improvement in biomass yield than that of a single-stage batch system). At an industrial scale, this biomass could undergo further downstream processing to generate a multistreamline of high valued by-products such as e.g. vitamins, pharmaceuticals and human nutrition, which can subsequently contribute to a significant improvement in an economic viability of biohydrogen process.
A continuum damage approach for predicting creep crack growth failures in components containing residual stresses
Creators: name: Zhou, Haoliang
Publisher: name: Imperial College London
Year: 2014

description: Components in advanced gas cooled reactor (AGR) operating at elevated temperatures in the range of 500-650°C are typically susceptible to the initiation and growth of cracks due to creep. Type 316H stainless steel steam headers after a long term service are susceptible to reheat cracking in the vicinity of the weld driven by the presence of welding residual stresses. For this reason, this research has focused on developing pragmatic numerical methods for predicting creep crack growth behaviour of welded components containing residual stresses, using a simplified continuum damage and fracture mechanics method. The work presented had three main aims. The first was to derive a comprehensive set of plastic η factors for standard fracture mechanics geometries containing welds. The impetus for this was to improve material crack growth characterisation for welds by improving the creep C* solutions for these geometries that are presently recommended in standard codes of practice for creep crack growth testing. The second part was to experimentally examine appropriate creep material properties for as-received and service-exposed 316H stainless steels containing welds for use in numerical modelling and predictive methods for creep crack growth in a real component. The third was to develop and validate a simplified method of simulating residual stresses and creep crack growth behaviour in an ex-service AISI 316H weld header with reheat cracking. This approach simulates the presence of residual stresses using appropriate loading and boundary conditions in actual components that undergo reheat cracking without the need to develop full weld simulations to quantify them. The creep crack growth behaviour was studied using two methods based on the theories of fracture mechanics and continuum damage mechanics. Fracture mechanics parameter C* was firstly used to examine the approximate crack growth rate using the reference stress approach and approximate NSW model. The second method was to predict long term cracking by using a simplified continuum damage mechanics model, with a consideration of stress relaxation. For this purpose, a simplified multi-axial ductility exhaustion model was developed and implemented in an Abaqus user subroutine, taking into account the changes in the ex-service creep properties and the effect of reduction in creep ductility under low loads and long term operation at service temperatures. Resulting from the findings, the task was to identify the geometric and the material reasons of how and why the crack growth follows a path of least resistance and higher constraint which did not necessarily mean growing through the welds or the heat affected zone region.
The stability of boundary layers on curved surfaces and surfaces involving abrupt changes
Creators: name: Nutter, Jamie Ian
Publisher: name: Imperial College London
Year: 2015

description: This thesis is concerned with the effect that boundary-layer instabilities have on laminar- turbulent transition over a commercial aircraft wing. We consider the effect that changing the structure of a wing’s surface may have on these instabilities. This thesis is separated into two parts, each concerning a different instability. Firstly our focus is on Tollmien-Schlichting waves; we investigate how abrupt changes may affect boundary-layer transition. The abrupt changes considered are junctions between rigid and porous surfaces. A local scattering problem is formulated; the abrupt changes cause waves to scatter in a subsonic boundary layer. The mechanism is described mathematically by using a triple-deck formalism, while the analysis across the junctions is based in a Wiener- Hopf factorisation. The impact of the wall junctions is characterised by a transmission coefficient, defined as the ratio of the amplitudes of the transmitted and incident waves. From our analysis we determine the effectiveness of porous strips in delaying transition. In the second part of this thesis we concentrate on a curved wing. Over curved sur- faces Go ̈rtler vortices may be generated; our focus is on long-wavelength Go ̈rtler vortices and the effect of changing curvature. The flow is described using a three-tiered system that balances the displacement and centrifugal forces. Two different problems concerning Go ̈rtler vortices are investigated, firstly we consider the effect of slowly varying curvature. Using a WKB approximation we derive multi-scale systems of equations, allowing us to find leading-order analytic solutions. The second problem concerning curved surfaces considers the effect of long-wavelength Go ̈rtler vortex-wave interaction. We use vortex-wave interaction theory to describe the evo- lution of this nonlinear interaction over a concave surface, where the curvature is modified in the streamwise direction. Analytical solutions are found for the vortex-induced shear stress and the wave pressure amplitude, using these solutions we solve for the remaining variables numerically.
Analysing datafied life
Creators: name: Yang, Xian
Publisher: name: Imperial College London
Year: 2015

description: Our life is being increasingly quantified by data. To obtain information from quantitative data, we need to develop various analysis methods, which can be drawn from diverse fields, such as computer science, information theory and statistics. This thesis focuses on investigating methods for analysing data generated for medical research. Its focus is on the purpose of using various data to quantify patients for personalized treatment. From the perspective of data type, this thesis proposes analysis methods for the data from the fields of Bioinformatics and medical imaging. We will discuss the need of using data from molecular level to pathway level and also incorporating medical imaging data. Different preprocessing methods should be developed for different data types, while some post-processing steps for various data types, such as classification and network analysis, can be done by a generalized approach. From the perspective of research questions, this thesis studies methods for answering five typical questions from simple to complex. These questions are detecting associations, identifying groups, constructing classifiers, deriving connectivity and building dynamic models. Each research question is studied in a specific field. For example, detecting associations is investigated for fMRI signals. However, the proposed methods can be naturally extended to solve questions in other fields. This thesis has successfully demonstrated that applying a method traditionally used in one field to a new field can bring lots of new insights. Five main research contributions for different research questions have been made in this thesis. First, to detect active brain regions associated to tasks using fMRI signals, a new significance index, CR-value, has been proposed. It is originated from the idea of using sparse modelling in gene association study. Secondly, in quantitative Proteomics analysis, a clustering based method has been developed to extract more information from large scale datasets than traditional methods. Clustering methods, which are usually used in finding subgroups of samples or features, are used to match similar identities across samples. Thirdly, a pipeline originally proposed in the field of Bioinformatics has been adapted to multivariate analysis of fMRI signals. Fourthly, the concept of elastic computing in computer science has been used to develop a new method for generating functional connectivity from fMRI data. Finally, sparse signal recovery methods from the domain of signal processing are suggested to solve the underdetermined problem of network model inference.
Towards single cell protein analysis of cardiac progenitor cells
Creators: name: Milman, Gemma
Publisher: name: Imperial College London
Year: 2015

description: Studying single cell protein expression is becoming increasingly important; however it is limited by the availability of highly sensitive technology. In adult cardiac progenitor cells (CPCs), expression of all the key cardiac transcription factors can be found, and both in vivo and in vitro studies have shown they can form cells of the cardiac lineage. However, effective mobilisation of these cells in situ for heart regeneration remains elusive. Close examination of CPCs for the important interactions and modifications may reveal the control mechanisms holding them in their arrested state, and therefore could lead to more effective cell therapies for heart failure. Total internal reflection microscopy is a super-resolution technique, allowing the visualisation of individual protein molecules through fluorescent labelling. It uses and immunoassay to pull down the protein of interest, detecting the protein with a secondary fluorescently labelled antibody. Whilst the assay sensitivity relies heavily on the antibody kinetics, it avoids the need to genetically modify proteins with fluorescence. Thus the assay can be adapted to look at any protein, in any cell, and can be multiplexed to examine many proteins simultaneously. In this thesis, an assay for the detection of the cardiac transcription factor, Gata-4, is developed. Gata-4 is pivotal for cardiac development; it is a part of an extensive gene regulatory network, interacting with many other key transcription factors to confer precise heart morphogenesis. It is expressed in cardiac progenitor cells, and the aim here was to quantify protein expression from single CPCs. Another facet examined here was the potential use of alternative protein capture agents. DNA oligonucleotides, encoding the consensus binding sequence for Gata-4 was investigated for its suitability in an assay for single cell protein expression. Whilst this yielded promising results it was constrained by the lack of a suitable negative control.

description: We analyze the physics of accelerated particle detectors (such as atoms) crossing optical cavities. In particular we focus on the detector response as well as on the energy signature that the detectors imprint in the cavities. In doing so, we examine to what extent the usual approximations made in quantum optics in cavities (such as the single-mode approximation, or the dimensional reduction of 3+1D cavities to simplified 1+1D setups) are acceptable when the atoms move in relativistic trajectories. We also study the dependence of these approximations on the state of the atoms and the relativistic nature of the trajectory. We find that, on very general grounds, and already in the weak coupling limit, single- and few-mode approximations, as well as 1+1D dimensional reductions, yield incorrect results when relativistic scenarios are considered.

description: Introduction: Pneumococcal diseases (including septicemia, meningitis, pneumonia, and upper respiratory infections) constitute a major public health problem. The World Health Organization recommends pneumococcal conjugate vaccine immunization of young children worldwide. Areas covered: We reviewed evidence on the effects of the 10-valent pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV), which is used in childhood immunization programs in over 45 countries or regions. The effectiveness of PHiD-CV against invasive pneumococcal disease (IPD), pneumonia, and acute otitis media was assessed. We also present its effect on pneumococcal nasopharyngeal carriage (NPC) and indirect effects (herd protection) among unvaccinated individuals. Expert commentary: Results from randomized, double-blind trials and post-marketing studies in various countries provide evidence of the protective efficacy, effectiveness, and impact of PHiD-CV against pneumococcal diseases. Data from different geographic locations also show reductions in NPC of vaccine pneumococcal serotypes, laying the foundation for indirect protection against pneumococcal disease. In countries where PHiD-CV is included in childhood immunization programs, there are signs of herd protection for vaccine serotypes among unvaccinated individuals. Although increases in non-vaccine serotype IPD and NPC rates were observed, there was an overall reduction of pneumococcal disease.

The decree has been dated by most scholars between 491 and 485. However, from the palaeographic point of view, there are several elements that would allow us to date it to the end of the 6th century BC.

description: As the data on CMB anisotropies improve and potential cosmological applications are realized, it will be increasingly important for theoretical calculations to be as accurate as possible. All modern calculations for inflationary-inspired fluctuations involve the numerical solution of coupled Boltzmann equations. There are many assumptions and choices to be made when carrying out such calculations. We go through each in turn, pointing out the best selections to make, and the level of inaccuracy expected through incorrect choice: (1) neglecting the effects of neutrinos or polarization has a 10% effect; (2) varying radiation temperature and He fraction can have smaller, but noticeable effects; (3) numerical issues, such as k-range and smoothing are discussed; (4) short-cut methods, e.g. free-streaming and tilt approximations, are generally inadequate at the few % level; (5) at the 1% level somewhat baroque effects are important, such as He recombination and even minimal reionization; (6) at smaller angular scales there are secondary effects which will ultimately have to be considered. Extracting information from the subsidiary acoustic peaks and the damping region will be an extremely challenging problem. However, given the prospect of measuring just such information on the sky, it will be important to meet this challenge. In principle we can obtain details about reionization history, neutrino contribution, helium abundance, non-power-law initial conditions etc.

description: The first observations of the recently completed Wisconsin H-Alpha Mapper (WHAM) facility include a study of emission lines from high velocity clouds in the M, A, and C complexes, with most of the observations on the M I cloud. We present results including clear detections of H-alpha emission from all three complexes with intensities ranging from 0.06 R to 0.20 R. In every observed direction where there is significant high velocity H I gas seen in the 21 cm line we have found associated ionized hydrogen emitting the H-alpha line. The velocities of the H-alpha and 21 cm emission are well correlated in every case except one, but the intensities are not correlated. There is some evidence that the ionized gas producing the H-alpha emission envelopes the 21 cm emitting neutral gas but the H-alpha "halo", if present, is not large. If the H-alpha emission arises from the photoionization of the H I clouds, then the implied Lyman continuum flux F_{LC} at the location of the clouds ranges from 1.3 to 4.2 x 10^5 photons cm^{-2} s^{-1}. If, on the other hand, the ionization is due to a shock arising from the collision of the high-velocity gas with an ambient medium in the halo, then the density of the pre-shocked gas can be constrained. We have also detected the [S II] 6716 angstrom line from the M I cloud and have evidence that the [S II] to H-alpha ratio varies with location on the cloud.

description: Depletion-driven assembly has been widely studied for micron-sized colloids, but questions remain at the nanoscale where the governing physics are impacted by the stabilizing surface ligands or wrapping polymers, whose length scales are on the same order as those of the colloidal core and the depletant. Here, we probe how wrapping colloidal tin-doped indium oxide nanocrystals with polymers affects their depletion- induced interactions and assembly in solutions of polyethylene glycol. Copolymers of polyacrylic acid grafted with polyethylene oxide provide nanocrystal wrappings with different effective polymer graft densities and molecular weights. (Ultra) small angle X-ray scattering, coarse-grained molecular dynamics simulation, and molecular thermo- dynamic theory were combined to analyze how depletant size and polymer wrapping characteristics affect depletion interactions, structure, and phase behavior. The re- sults show how depletant molecular weight, as well as surface density and molecular weight of polymer grafts, set thresholds for assembly. These signatures are unique to depletion-driven assembly of nanoscale colloids and mirror phase behaviors of grafted nanoparticle–polymer composites. Optical and rheological responses of depletion-driven assemblies of nanocrystals with different polymer shell architectures were probed to learn how their structural differences impact properties. We discuss how these han- dles for depletion-driven assembly at the nanoscale may provide fresh opportunities for designing responsive depletion interactions and dynamically reconfigurable materials.
PSR J0045-7319: A DUAL-LINE BINARY RADIO PULSAR

description: Binary radio pulsars are superb tools for mapping binary orbits, because of the precision of the pulse timing method (Taylor and Weisberg 1989). To date, all orbital parameters for binary pulsars have been derived from observations of the pulsar alone. We present the first observations of the radial velocity variations due to the binary motion of a companion to a radio pulsar. Our results demonstrate that the companion to the Small Magellanic Cloud pulsar PSR J0045-7319 is the B1V star identified by Kaspi et al. (1994). The mass ratio of the system is 6.3 +/- 1.2, which, for a neutron star mass of 1.4 Mo, implies a mass of 8.8 +/- 1.8 Mo for the companion, consistent with the mass expected for a B1V star. The inclination angle for the binary system is therefore 44 +/- 5 degrees, and the projected rotational velocity of the companion is 113 +/- 10 km/s. The heliocentric radial velocity of the binary system is consistent with that of other stars and gas in the same region of the Small Magellanic Cloud.

Quantification of cortical folding using MR image data
Creators: name: Wright, Robert
Publisher: name: Imperial College London
Year: 2015

description: The cerebral cortex is a thin layer of tissue lining the brain where neural circuits perform important high level functions including sensory perception, motor control and language processing. In the third trimester the fetal cortex folds rapidly from a smooth sheet into a highly convoluted arrangement of gyri and sulci. Premature birth is a high risk factor for poor neurodevelopmental outcome and has been associated with abnormal cortical development, however the nature of the disruption to developmental processes is not fully understood. Recent developments in magnetic resonance imaging have allowed the acquisition of high quality brain images of preterms and also fetuses in-utero. The aim of this thesis is to develop techniques which quantify folding from these images in order to better understand cortical development in these two populations. A framework is presented that quantifies global and regional folding using curvature-based measures. This methodology was applied to fetuses over a wide gestational age range (21.7 to 38.9 weeks) for a large number of subjects (N = 80) extending our understanding of how the cortex folds through this critical developmental period. The changing relationship between the folding measures and gestational age was modelled with a Gompertz function which allowed an accurate prediction of physiological age. A spectral-based method is outlined for constructing a spatio-temporal surface atlas (a sequence of mean cortical surface meshes for weekly intervals). A key advantage of this method is the ability to do group-wise atlasing without bias to the anatomy of an initial reference subject. Mean surface templates were constructed for both fetuses and preterms allowing a preliminary comparison of mean cortical shape over the postmenstrual age range 28-36 weeks. Displacement patterns were revealed which intensified with increasing prematurity, however more work is needed to evaluate the reliability of these findings.

Sensing of circulating microRNAs using high-throughput droplet-based microfluidics: a non-invasive diagnostic tool for cancer
Creators: name: Hinesh, Patel
Publisher: name: Imperial College London

description: Cancer is a leading cause of mortality worldwide, and important strategies to mitigate cancer burden include improved diagnostics for early detection and subsequent treat- ment. Among potential cancer biomarkers, microRNAs (miRNAs) are ideal for a rapid, minimally-invasive, and early-stage diagnostic with high disease specificity. MiRNAs are a robust class of small non-coding segments of RNA shown to exhibit altered expression profiles in different types of cancer. In addition, they are easily accessible in various bi- ological media (saliva, plasma, urine, etc.), and exist in highly stable forms resistant to nuclease activity and harsh conditions of pH and temperature. Herein we describe the first steps toward a sensitive and specific microfluidic-based detection platform for high- throughput profiling of miRNAs. We utilise 7-mer peptide nucleic acid (PNA) probes functionalized at the 51 and 31 ends with original optical probe heads. Detection occurs through miRNA-templated fluorogenic reactions of either trimethine cyanine dye (Cy3) synthesis or coumarin unquenching (fluorescence unmasking). Briefly, upon hybridiza- tion of the synthetic probes to a complementary nucleic acid target, both probe-heads are brought in close enough proximity to react with each other, thus generating the fluorescent product (while the reaction is highly unfavourable in the absence of nucleic acid template). The characteristic fluorescent signal emitted can therefore be directly linked to the detec- tion of the targeted sequence. In case of a partial or incomplete hybridisation of one of the probe (e.g. as a consequence of a SNP), a significant decrease in reaction efficiency (i.e. a weaker fluorescence) is observed. Thus far our system has shown sub-micromolar sensitivity and is compatible for detection in crude plasma, serum, and saliva samples with minimal pre-processing. Multiplexing can be achieved through simple modification of precursor moieties affording non-overlapping, multi-coloured system for the detection of different cancer biomarkers in parallel.

description: Although squamates are commonly found in Cenozoic South American deposits, most findings correspond to fragmentary cranial materials or isolated vertebrae. Among the known South American vertebrate fossil localities, the lower section of the Chichinales Formation (Early Miocene, Colhuehuapian South American Land Mammal Age [SALMA]), in Paso Córdoba Protected Natural Area, Río Negro Province, Argentina, recently yielded an almost complete skull of a previously unknown teiid lizard. Here, we provide a detailed description of this new fossil, based on stereoscopic and high-resolution X-ray computed tomography (CT scan) analyses. Our phylogenetic analysis recovered the new fossil within the monophyletic genus Callopistes, as the sister group of the fossil C. bicuspidatus from upper Miocene–lower Pliocene sediments (Montehermosan SALMA) of the Monte Hermoso Formation. The new species antedates the oldest previously known fossil record of the genus by at least 14 Ma, providing a minimum age of origin for the genus of approximately 20.1 Ma (based on recent revisions of the Cenozoic fossil record of SALMA). The current distribution of the two known extant species of Callopistes and the locality from which the new taxon was recovered indicate that this genus had a much broader distribution in the past that included cis-Andean areas of Patagonia during the Miocene. Our phylogenetic results further suggest that Tupinambis uruguaianensis should be allocated to the genus Dracaena. http://zoobank.org/urn:lsid:zoobank.org:pub:452C7D2A-6819-4488-9C28-1020EBD71F91 SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at www.tandfonline.com/UJVP Citation for this article: Quadros, A.
