description: Blazars and in particular the subclass of high synchrotron peaked Active Galactic Nuclei are among the main targets for the present generation of Imaging Atmospheric Cherenkov Telescopes (IACTs) and will remain of great importance for very high-energy $γ$-ray science in the era of the Cherenkov Telescope Array (CTA). Observations by IACTs, which have relatively small fields of view ($\sim$ few degrees), are limited by viewing conditions; therefore, it is important to select the most promising targets in order to increase the number of detections. The aim of this paper is to search for unclassified blazars among known $γ$-ray sources from the Fermi Large Area Telescope (LAT) third source catalog that are likely detectable with IACTs or CTA. We use an artificial neural network algorithm and updated analysis of Fermi-LAT data. We found 80 $γ$-ray source candidates, and for the highest-confidence candidates, we calculate their potential detectability with IACTs and CTA based on an extrapolation of their energy spectra. Follow-up observations of our source candidates could significantly increase the current TeV source population sample and could ultimately confirm the efficiency of our algorithm to select TeV sources.

description: Investment in seaweed (Eucheuma) culture by small farmers in Indonesian coastal areas is now considerable, but there appears to be no estimates of the economic returns from this activity. After providing background information on seaweed farms, cost of establishing a seaweed farm and farm revenue from seaweed farming, we estimate the economic returns from seaweed farming using data obtained from Bali. It is estimated that the economic rate of returns in investment in seaweed farming in Bali is very high and the pay-back period for this activity on most farm surveyed was less than a year. Currently small farmers can depend on this culture as their main source of household income in areas ecologically suitable for this culture provided market-access is not too difficult. This culture would also seem to be environmentally less damaging than many existing mariculture activities, e.g. shrimp farming. In addition, it is relatively labour-intensive and does not require significant quantities of processed or imported inputs such as fertilisers, chemicals, fuel and food. Indications are that seaweed farming is likely to be economically more attractive than giant clam mariculture in Bali.

description: Biocompatible polymers with the ability to load and release a cargo at the site of action in a smart response to stimuli have attracted great attention in the field of drug delivery and cancer therapy. In this work, we synthesize a dual-responsive dendritic polyglycerol sulfate (DR-dPGS) drug delivery system by copolymerization of glycidol, ε-caprolactone and an epoxide monomer bearing a disulfide bond (SSG), followed by sulfation of terminal hydroxyl groups of the copolymer. The effect of different catalysts, including Lewis acids and organic bases, on the molecular weight, monomer content and polymer structure was investigated. The degradation of the polymer backbone was proven in presence of reducing agents and candida antarctica Lipase B (CALB) enzyme, which results in the cleavage of the disulfides and ester bonds, respectively. The hydrophobic anticancer drug Doxorubicin (DOX) was loaded in the polymer and the kinetic assessment showed an enhanced drug release with glutathione (GSH) or CALB as compared to controls and a synergistic effect of a combination of both stimuli. Cell uptake was studied by using confocal laser scanning microscopy with HeLa cells and showed the uptake of the Dox-loaded carriers and the release of the drug into the nucleus. Cytotoxicity tests with three different cancer cell lines showed good tolerability of the polymers of as high concentrations as 1 mg mL−1, while cancer cell growth was efficiently inhibited by DR-dPGS@Dox.

description: The synthesis of stable blue TADF emitters and the corresponding matrix materials is one of the biggest challenges in the development of novel OLED materials. We present six bipolar host materials based on triazine as an acceptor and two types of donors, namely, carbazole, and acridine. Using a tool box approach, the chemical structure of the materials is changed in a systematic way. Both the carbazole and acridine donor are connected to the triazine acceptor via a para- or a meta-linked phenyl ring or are linked directly to each other. Thephotophysicsofthematerialshasbeeninvestigatedindetailby absorption-, ﬂuorescence-, and phosphorescence spectroscopy in solution. In addition, a number of DFT calculations have been made which result in a deeper understanding of the photophysics. The presence of a phenyl bridge between donor and acceptor cores leads to a considerable decrease of the triplet energy due to extension of the overlap electron and hole orbitals over the triazine-phenyl core of the molecule. This decrease is more pronounced for the para-phenylene than for the meta-phenylene linker. Only direct connection of the donor group to the triazine core provides a high energy of the triplet state of 2.97eV for the carbazole derivative CTRZ and 3.07eV for the acridine ATRZ. This is a major requirement for the use of the materials as a host for blue TADF emitters.

description: During 1991 research based on the test-marketing of giant clams as aquarium species was conducted in Brisbane, Queensland. The results indicated giant clams to be potentially popular as aquarium specimens, being considered to be on a par with coral and anemones. However, the marketability of giant clams in Queensland was dampened by the requirements of the Queensland Department of Primary Industries, which compelled both retailers and customers to obtain permits to hold clams. Permits for retailers were expensive; being $100 per aquarium, and those for customers required a time-consuming application process. The results of this test-marketing are reported in Economics of Giant Clam Mariculture, Research Report or Paper No. 26. For comparison with Brisbane .results, a telephone survey was conducted in Sydney and Melbourne, the capital cities of the two most populous states of Australia, New South Wales and Victoria. Insufficient resources were available to adopt test-marketing 1n those cities. The results of these surveys support the conclusions of the first, that a small but viable market exists for giant clams as aquarium specimens throughout Australia. Profit margins for retailing of clams in Sydney and Melbourne seem to be higher than in Queensland, partly due to the absence of Queensland's expensive permit requirements. Other differences are also noted. The economic experience of two retailers in Sydney and Melbourne selling farmed giant clams in relatively large quantities is encouraging.

description: We present HST Faint Object Camera observations of the asteroid 1 Ceres at near-, mid-, and far-UV wavelengths (lambda = 3636, 2795, and 1621 A, respectively) obtained on 1995 June 25. The disk of Ceres is well-resolved for the first time, at a scale of ~50km. We report the detection of a large, ~250km diameter surface feature for which we propose the name ``Piazzi''; however it is presently uncertain if this feature is due to a crater, albedo variegation, or other effect. From limb fits to the images, we obtain semi-major and semi-minor axes of R_1=484.8+/-5.1km and R_2=466.4+/-5.9km, respectively, for the illumination-corrected projected ellipsoid. Although albedo features are seen, they do not allow for a definitive determination of the rotation or pole positions of Ceres, particularly because of the sparse sampling (two epochs) of the 9 hour rotation period. From full-disk integrated albedo measurements, we find that Ceres has a red spectral slope from the mid- to near-UV, and a significant blue slope shortward of the mid-UV. In spite of the presence of Piazzi, we detect no significant global differences in the integrated albedo as a function of rotational phase for the two epochs of data we obtained. From Minnaert surface fits to the near- and mid-UV images, we find an unusually large Minnaert parameter of k~0.9, suggesting a more Lambertian than lunar-like surface.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We discuss two dedicated observables in exclusive B -> K* l+ l- decay that can be used to study effects of physics beyond the standard model, namely the forward-backward asymmetry in the lepton spectrum and the isospin-asymmetry between decays of charged and neutral B mesons. We consider the region of large recoil-energy (i.e. small invariant mass of the lepton pair), and employ the QCD factorization approach to exclusive B meson decays. Sub-leading effects in the heavy quark mass expansion have been taken into account for the calculation of the isospin-asymmetry. We give predictions for decay asymmetries in the standard model, and its supersymmetric extension with minimal flavor violation, using parameter values allowed by current experimental constraints on B->X_s gamma decay.

description: Biocides are frequently applied as disinfectants in animal husbandry to prevent the transmission of drug-resistant bacteria and to control zoonotic diseases. Concerns have been raised, that their use may contribute to the selection and persistence of antimicrobial-resistant bacteria. Especially, extended-spectrum β-lactamase- and AmpC β-lactamase-producing Escherichia coli have become a global health threat. In our study, 29 ESBL-/AmpC-producing and 64 NON-ESBL-/AmpC-producing E.coli isolates from three German broiler fattening farms collected in 2016 following regular cleaning and disinfection were phylogenetically characterized by whole genome sequencing, analyzed for phylogenetic distribution of virulence-associated genes, and screened for determinants of and associations between biocide tolerance and antibiotic resistance. Of the 30 known and two unknown sequence types detected, ST117 and ST297 were the most common genotypes. These STs are recognized worldwide as pandemic lineages causing disease in humans and poultry. Virulence determinants associated with extraintestinal pathogenic E.coli showed variable phylogenetic distribution patterns. Isolates with reduced biocide susceptibility were rarely found on the tested farms. Nine isolates displayed elevated MICs and/or MBCs of formaldehyde, chlorocresol, peroxyacetic acid, or benzalkonium chloride. Antibiotic resistance to ampicillin, trimethoprim, and sulfamethoxazole was most prevalent. The majority of ESBL-/AmpC-producing isolates carried blaCTX-M (55%) or blaCMY-2 (24%) genes. Phenotypic biocide tolerance and antibiotic resistance were not interlinked. However, biocide and metal resistance determinants were found on mobile genetic elements together with antibiotic resistance genes raising concerns that biocides used in the food industry may lead to selection pressure for strains carrying acquired resistance determinants to different antimicrobials.
Quantifying nonlocality as a resource for device-independent quantum key distribution
Creators: name: Camalet, S.
Publisher: name: arXiv
Year: 2019
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We introduce, for any bipartite Bell scenario, a measure that quantifies both the amount of nonlocality and the efficiency in device-independent quantum key distribution of a set of measurement outcomes probabilities. It is a proper measure of nonlocality as it vanishes when this set is Bell local and does not increase under the allowed transformations of the nonlocality resource theory. This device-independent key rate $R$ is defined by optimizing over a class of protocols, to generate the raw keys, in which each legitimate party does not use just one preselected measurement but randomly chooses at each round one among all the measurements at its disposal. A common and secret key can certainly be established when $R$ is positive but not when it is zero. For any continuous proper measure of nonlocality $N$, $R$ is tightly lower bounded by a nondecreasing function of $N$ that vanishes when $N$ does. There can thus be a threshold value for the amount of nonlocality as quantified by $N$ above which a secret key is surely achievable. A readily computable measure with such a threshold exists for two two-outcome measurements per legitimate party.

description: Technology adoption is seen as an important tool for increasing agricultural efficiency and combating food insecurity. Despite this theory, Sub-Saharan Africa, which suffers from one of the highest rates of food insecurity, has one of the lowest rates of technology adoption. This is especially prevalent among female headed households. Accordingly, the objective of this paper is to investigate the dynamics of technology adoption at household level and further disaggregate it by gender. Using four waves of Ugandan household level panel data, we find that technology adoption in the first period is the primary determinant of technology adoption in the subsequent periods. Gender level analysis shows that this finding is dominant by male headed households who make the majority of the sample. In contrast, lagged technology adoption is the main driver of adoption for female headed households.

Effects of strain-rate and temperature on ductile damage and Fracture of metallic materials
Creators: name: Sancho Garcia, Alexander
Publisher: name: Imperial College London
Year: 2018

description: Ductile damage appears in metallic materials when they undergo sufficiently high plastic strain. It is caused by voids and produces degradation on the mechanical properties that eventually leads to the ductile fracture of the material. Like other properties, this behaviour is affected by the temperature and velocity of material deformation. This thesis investigates the effects that temperature and strain-rate have on ductile damage from an experimental and a modelling point of view, and explores innovative experimental methods to quantify damage and models to represent it. Experimental tests for the characterisation of plasticity, ductile damage and ductile fracture were conducted on stainless steel 304L and copper C110. The experiments were run at three temperatures ranging from −80◦C to 180◦C, and at three strain-rates from 10−3 s−1 to 104 s−1. For the accurate representation of plasticity near fracture, a neck monitoring method was implemented from which local stresses and strains can be calculated once localisation occurs. The method was also employed to analyse the effect of stress triaxiality on fracture using notched samples. Ductile damage accumulation was obtained from the degradation of the elastic modulus and validated by a micrographic analysis of the samples. The experiments at different temperatures were conducted following the same methodology inside an environmental chamber. To be able to apply the techniques to high-speed tests, an in-situ shadowgraph method was developed and a sub-pixel edge detection algorithm implemented, resulting in very high quality results, even at the highest strain-rate tested. An innovative experimental rig was also designed to perform high-speed interrupted tests from which damage accumulation was measured. Making use of the experimental results, plasticity, ductile damage and fracture models were calibrated and their effectiveness assessed. Novel ductile fracture and damage accumulation models were developed, which include the effects of strain-rate and temperature. The models also include non-linear damage accumulation, and are capable of representing accurately the effects observed in the experiments.

description: The spectrum of excited states observed in the finite volume of lattice QCD is governed by the discrete symmetries of the cubic group. This finite group permits the mixing of orbital angular momentum quanta in the finite volume. As experimental results refer to specific angular momentum in a partial-wave decomposition, a formalism mapping the partial-wave scattering potentials to the finite volume is required. This formalism is developed herein for Hamiltonian effective field theory, an extension of chiral effective field theory incorporating the Lüscher relation linking the energy levels observed in finite volume to the scattering phase shift. The formalism provides an optimal set of rest-frame basis states maximally reducing the dimension of the Hamiltonian, and it should work in any Hamiltonian formalism. As a first example of the formalism's implementation, lattice QCD results for the spectrum of an isospin-2 $ππ$ scattering system are analyzed to determine the $s$, $d$, and $g$ partial-wave scattering information.

Lipophilic and cationic gallium-68 chelates for mitochondrial imaging
Creators: name: Smith, Adam James
Publisher: name: Imperial College London
Year: 2018

description: This thesis details the synthesis and radiolabelling of gallium-68-labelled radiotracers for mitochondrial imaging, as well as their uptake in in vitro and ex vivo biological models. These tracers are designed to be cationic such that they are taken up into mitochondria in a manner dependant on their mitochondrial membrane potential, and lipophilic such that they can pass through lipid bilayer membranes. The synthesis of novel gallium chelators is described in Chapter 3. Starting with triarylphosphonium (TAP)-functionalised DO3A as a base case, DO2A-based variants were synthesised due to their novelty in the literature, using TAP and aryl functionalisation to provide tracers with a range of cationic charges and lipophilicities. Bridged cyclens were also explored with a view to exploiting their preorganisation and complex stability, whilst work into synthesising HBED-based chelators was unsuccessful due to low stability of the chelators. The radiolabelling of the chelators with generator-produced gallium-68 is described in Chapter 4. DO3A-based ligands were found to radiolabel in near-quantitative RCY as one species after heating at 100 °C for 30 min. After changing the radiolabelling buffer, near quantitative RCYs were achieved for the DO2A-based compounds, however HPLC showed that these tracers exist as multiple species. Altering reaction conditions revealed that these species exist as kinetic/thermodynamic pairs, although it was not possible to completely isolate a single species. Log D values of -1.81, -0.28 and -0.07 were obtained for DO3A-TXP, DO2A-TXP and DO2A-Xy compounds respectively. Quantitative RCY was obtained for diacid functionalised bridged cyclen, although its log D was lower than that of unchelated gallium. The three candidate radiotracers discussed previously were taken forward to testing in biological models, the results of which are described in Chapter 5. The cardiac uptake of the radiotracers was determined ex vivo using an isolated perfused heart model and mitochondrial membrane potential decoupler challenge. Both DO2A-TXP and DO2A-Xy showed a significant change in uptake upon mitochondrial challenge, although it was found that log D alone is not an exact predictor of myocardial uptake. In vitro tumour cell uptake was also assessed for DO3A-TXP, showing a significant increase in uptake compared to unchelated gallium. Chapter 6 summarises the overall conclusions of the thesis and suggests further work in this area. Chapter 7 provides experimental procedures.

description: The small scale cattle fattening enterprise is represents an important component of the agribusiness sector of the economy with great economic, income, poverty reduction and social implications. A large number of farmers involved in cattle fattening just before 3 or 4 months of Eid-ul-Azha (Muslim festival), when they sell the animals with profitable prices. Cattle fattening for beef production have become an important business of the small farmers in Bangladesh. This study examined the profitability as well as operational economics efficiency of cattle fattening enterprise of Rajbari District. Data used to achieve this objective was obtained from 120 nomadic farmers, which were randomly selected using a multi-stage sampling procedure. Data were generated using a survey schedule as well as direct observation (cost-route method). Descriptive statistics, economics analysis as well as operational efficiency index were used to analyze the data. Results showed that small scale cattle fattening enterprise were profitable and flexible. A net enterprise income of BDT 5559 per cattle was realized by an average enterprise in study area. It was also shown that operational efficiency was not generally high among the entrepreneur. Based on these results, the study advised less efficient entrepreneurs to adopt the practices of the efficient ones in order to make the enterprise more profitable. The study shows that small scale cattle fattening enterprise is profitable due to agribusiness context. Farmers used three years old cattle for beef fattening. Cattle fattening period is 4.5 months in rural study areas of Rajbari district in Bangladesh.

description: We study heavy-light four-point function by employing Lorentzian inversion formula, where the conformal dimension of heavy operator is as large as central charge $C_T\rightarrow\infty$. We implement the Lorentzian inversion formula back and forth to reveal the universality of the lowest-twist multi-stress-tensor $T^k$ as well as large spin double-twist operators $[\mathcal{O}_H\mathcal{O}_L]_{n',J'}$. In this way, we also propose an algorithm to bootstrap the heavy-light four-point function by extracting relevant OPE coefficients and anomalous dimensions. By following the algorithm, we exhibit the explicit results in $d=4$ up to the triple-stress-tensor. Moreover, general dimensional heavy-light bootstrap up to the double-stress-tensor is also discussed, and we present an infinite series representation of the lowest-twist double-stress-tensor OPE coefficient. Exact expressions of lowest-twist double-stress-tensor OPE coefficients in $d=6,8,10$ are also obtained as further examples.

Nonlinear interactions of waves with arbitrarily-sheared currents
Creators: name: Beyer, Magnus
Publisher: name: Imperial College London
Year: 2018

description: The safe design of ships and offshore structures requires accurate predictions of the environmental loading. This includes the description of the interaction between waves, winds and currents. Indeed, there is strong evidence that wave-current interaction leads to the occurrence of extreme waves that cause the largest loading. Furthermore, strong winds, that produce extreme waves, simultaneously generate sheared currents that bring about a significant vorticity distribution, thus leading to rotational flows. As a result, potential wave theories (such as Stokes’ theory) become invalid. The aim of the present study is to improve the understanding of the influence of arbitrarily-sheared currents on regular waves and focused wave groups. The interaction of regular waves and currents is simulated by an irrotational multi-layer (Cummins & Swan, 1993) and a rotational polynomial streamfunction model (Swan & James, 2001). The interaction of focused wave groups and currents is simulated using a numerical, fully-nonlinear, rotational Green-Naghdi (GN) model (Webster & Shields, 1991). Results show that surface current velocity and vorticity significantly influence the wave steepness, the surface elevation and the wave-induced velocity. For focused wave groups the steepness increases by up to 23% compared to the waves-only solution. It is further demonstrated that surface vorticity counteracts the effect of depth-uniform currents. Evidence also proves that vorticity at the surface is important, whilst closer to the bed it is negligible. Moreover, additional rotational wave components due to vorticity were identified, which can contribute to the wave-induced velocity by up to 11%. The GN model has also been employed to investigate gradually-varying flows in which waves propagate onto currents. Under these conditions the wave amplitude can be significantly modified, which leads to much larger changes in the steepness (for example, for nonlinear focused wave groups this can be an increase of 46% compared to the waves-only solution), the crest elevation and the wave-induced velocity than observed for traditionally-studied equilibrium flow conditions. The present study provides conclusive evidence that surface vorticity must be considered in the design of offshore structures.

description: The G-function associated to the semi-simple Frobenius manifold C^n/W (where W is a Coxeter group or an extended affine Weyl group) is studied. The general form of the G function is given in terms of a logarithmic singularity over caustics in the manifold. The main result in this paper is a universal formula for the G-function corresponding to the Frobenius manifold C^n/W^(k)(A_{n-1}) where W^(k)(A_{n-1}) is a certain extended affine Weyl group (or, equivalently, corresponding to the Hurwitz space M_{0;k-1,n-k-1}), together with the general form of the G-function in terms of data on caustics. Symmetries of the G function are also studied.

description: We analyze the broad range of spin-dependent nonequilibrium transport properties of hybrid systems composed of a normal region tunnel coupled to two superconductors with exchange fields induced by the proximity to thin ferromagnetic layers and highlight its functionalities. By calculating the quasiparticle distribution functions in the normal region, we find that they are spin dependent and strongly sensitive to the relative angle between exchange fields in the two superconductors. The impact of inelastic collisions on their properties is addressed. As a result, the electric current flowing through the system is found to be strongly dependent on the relative angle between exchange fields, giving rise to a huge value of magnetoresistance. Moreover, the current presents a complete spin polarization in a wide range of bias voltages, even in the quasiequilibrium case. In the nonequilibrium limit, we parametrize the distributions with an �effective� temperature, which turns out to be strongly spin dependent, though quite sensitive to inelastic collisions. By tunnel coupling the normal region to an additional superconducting electrode, we show that it is possible to implement a spin-polarized current source of both spin species, depending on the bias voltages applied.

description: If A is a nonnegative matrix whose associated directed graph is strongly connected, the Perron-Frobenius theorem asserts that A has an eigenvector in the positive cone, (R^+)^n. We associate a directed graph to any homogeneous, monotone function, f: (R^+)^n -> (R^+)^n, and show that if the graph is strongly connected then f has a (nonlinear) eigenvector in (R^+)^n. Several results in the literature emerge as corollaries. Our methods show that the Perron-Frobenius theorem is ``really'' about the boundedness of invariant subsets in the Hilbert projective metric. They lead to further existence results and open problems.

description: The construction of photon-photon quantum phase gate based on photonic nonlinearity has long been a fundamental issue, which is vital for deterministic and scalable photonic quantum information processing. It requires not only strong nonlinear interaction at the single-photon level, but also suppressed phase noise and spectral entanglement for high gate fidelity. In this paper, we propose that high-quality factor microcavity with strong $χ^{(2)}$ nonlinearity can be quantized to anharmonic energy levels and be effectively treated as an artificial atom. Such artificial atom has a size much larger than the photon wavelength, which enables passive and active ultra-strong coupling to traveling photons. High-fidelity quantum control-phase gate is realized by mediating the phase between photons with an intermediate artificial atom in a photonic molecule structure. The scheme avoids the two-photon emission and thus eliminates the spectral entanglement and quantum phase noises. Experimental realization of the artificial atom can be envisioned on the integrated photonic chip and holds great potential for single-emitter-free, room-temperature quantum information processing.

Structural studies of membrane remodelling proteins

description: Membrane remodelling events underpin basic cell processes such as transport of nutrients, growth and respiration. Molecular details behind different remodelling events are largely unknown and often subject to action of different curvature-inducing proteins (CIPs). Here, the involvement of CIPs in two types of membrane remodelling events; fission and fusion is under investigation. Dynamin-like proteins perform membrane fission during the process of mitochondrial division. Currently, available structural data for dynamin-like proteins fail to sufficiently explain mechanistic details behind the fission event. All available crystal structures of dynamin homologs contain a self-assembly limiting mutation in the stalk region. Here, a crystal structure of a full-length eukaryotic dynamin-like protein (CmDnm1) in the native state is reported. The 7 Å structure uncovers a novel to eukaryotes hinge 1 closed conformation, which is also present in solution as shown by cysteine crosslinking and PET experiments. Moreover, a new tetrameric conformation of CmDnm1 in the off-membrane inactive state is visualised and validated by size exclusion chromatography, electron microscopy and protein crosslinking. In addition, negative-stain electron microscopy shows that CmDnm1 is able to remodel membranes by forming oligomeric rings that assembly into helical filaments. Based on the structural and biochemical data we propose a model for dynamin-like protein-driven membrane fission, in which dynamin is in the off-membrane novel tetrameric conformation, which self-assembles in the concentration dependent manner to form rings, which can then polymerase into long filaments and bend membranes. Thylakoid membranes are maintained by an interplay of fission and fusion events. Recently, Vesicle inducing protein in plastids 1 (Vipp1) was shown to trigger membrane fusion in cyanobacteria and chloroplasts. As no high-resolution structural data for Vipp1 proteins presently exists, current descriptions of the mechanism of membrane fusion rely on ~ 20 Å models of Vipp1 oligomeric rings. Here we show a cryo-EM structure of Vipp1 rings with a side-to-side rather than top-to-bottom arrangement of monomers. We identified lipid binding domains as the outer- and inner-most projections of the ring. In addition, Vipp1 filaments were characterised in more detail, uncovering a helical assembly pattern. Based on our Vipp1 structures, updated models for membrane fusion and oligomeric assembly are proposed.
