description: We studied several aspects of the Mott metal-insulator transition in the disordered case. The model on which we based our analysis is the disordered Hubbard model, which is the simplest model capable of capturing the Mott metal-insulator transition. We investigated this model through the Statistical Dynamical Mean-Field Theory (statDMFT). This theory is a natural extension of the Dynamical Mean-Field Theory (DMFT), which has been used with relative success in the last several years with the purpose of describing the Mott transition in the clean case. As is the case for the latter theory, the statDMFT incorporates the electronic correlation effects only in their local manifestations. Disorder, on the other hand, is treated in such a way as to incorporate Anderson localization effects. With this technique, we analyzed the disordered two-dimensional Mott transition, using Quantum Monte Carlo to solve the associated single-impurity problems. We found spinodal lines at which the metal and insulator cease to be meta-stable. We also studied spatial fluctuations of local quantities, such as the self-energy and the local Green's function, and showed the appearance of metallic regions within the insulator and vice-versa. We carried out an analysis of finite-size effects and showed that, in agreement with the theorems of Imry and Ma, the first-order transition is smeared in the thermodynamic limit. We analyzed transport properties by means of a mapping to a random classical resistor network and calculated both the average current and its distribution across the metal-insulator transition.

description: The mam purpose of this study is to provide the Brazilian Government wt th quantified projections of country demand for, production of, and trade m important agricultural commod1t1es. Under current conditions, Brazil Will have to import massive amounts of food m the next decade. The objective of satisfymg internal demand can be met by increasing yields and removal of restrictive policies. 111e results point to the continuation of low levels of per capita consumption. Policymakers must therefore turn to ways of improving the producer's expectation of better relative pnce conditions, maintain a realistic foreign exchange rate, and take measures to subs1d1ze food for the low income population. The idea of doubhng food production by 1995 to allow the country to be free of the risk limit of food scarcity and the dependence on foreign markets also requires the transformation of trad1t1onal farming methods through the use of higher yielding technologies. Agricultural research and extens10n will play an important role in the modernization process. Heavy investment will also be necessary for 1rr1gatmg crop land and the incorporat10n of new land areas.

description: An efficient implementation of the self-consistent GW method in the FlapwMBPT code (https://www.bnl.gov/cmpmsd/flapwmbpt/) is presented. It features the evaluation of polarizability and self-energy which scales linearly with respect to the system size. Altogether the computational time scaling was measured to be between linear and quadratic in the applications to silicon supercells with up to 72 atoms. Application to such materials as paracostibite CoSbS, supercells of La$_{2}$CuO$_{4}$ (up to 56 atoms) and SmB$_{6}$ illustrate the potential of the approach in computational material science.

description: The ability to recognize emotions from facial expressions is crucial for social interaction. Only few studies have examined the effect of stress hormones on facial emotion recognition, although stressful events affect social interactions on a daily basis. Those studies that examined facial emotion recognition mostly used explicit prompts to trigger consciously controlled processing. However, facial emotions are processed mainly implicitly in real life. Therefore, we investigated separate and combined effects of noradrenergic and glucocorticoid stimulation on implicit and explicit facial emotion recognition. One hundred and four healthy men (mean age = 24.1 years ± SD 3.5) underwent the Face Puzzle task to test implicit and explicit facial emotion recognition after receiving either 10 mg hydrocortisone or 10 mg yohimbine (an alpha 2-adrenergic receptor antagonist that increases noradrenergic activity) or 10 mg hydrocortisone/10 mg yohimbine combined or placebo. Salivary cortisol and salivary alpha amylase (sAA) were measured during the experiment. Compared to the placebo condition hydrocortisone significantly increased salivary cortisol and yohimbine significantly increased sAA. Participants were better and faster in explicit than in implicit facial emotion recognition. However, there was no effect of separate and combined noradrenergic and glucocorticoid stimulation on implicit and explicit facial emotion recognition performance compared to placebo. Our results do not support an essential role of the glucocorticoid and noradrenergic system in FER in young healthy men.

description: Approximately 6.2% of the world's population (466 million people) suffer from disabling hearing impairment [1]. Hearing impairment impacts negatively on one's education, financial success [2][3], cognitive development in childhood [4], including increased risk of dementia in older adulthood [5]. Lack of or reduced social interaction due to hearing impairment affects creating or maintaining healthy relationships at home, school and work [5]. Hence, hearing impairment genuinely affects the overall quality of life and wellbeing. The cocktail party effect, which is a healthy hearing individual's ability to understand one voice in a cacophony of other voices or sounds, is an important ability lacking in people with hearing impairment. This inability results in difficulties with simple daily activities such as partaking in group discussions or conversing in noisy restaurants [6]. This smart hearing aid aims to provide much-needed assistance with understanding speech in noisy environments. For example, if a person wants to partake in a group discussion, he/she needs to place the microphone array based unit on a flat surface in front of him/her, such as a table. When conversations take place, the microphone array will capture and process sound from all directions, intelligently prioritise and provide the lead speaker's voice by suppressing unwanted noises, including speeches of other people. This device selects and alternates voices between speakers automatically using voice algorithms. Additionally, the user has the option of further fine-tuning the acoustic parameters as needed through a smartphone interface. This paper describes the development and functions of this new Smart Hearing Aid.
Meson mixing amplitudes in asymmetric nuclear matter

description: Using a purely hadronic model, we study the charge-symmetry-breaking $ρ$-$ω$, $σ$-$δ$, $σ$-$ρ$ and $δ$-$ω$ mixing amplitudes in isospin asymmetric nuclear matter. The basic assumption of the model is that the mixing amplitude is generated by nucleon and anti-nucleon loops and hence driven entirely by the difference between proton and neutron Fermi momenta and the proton-neutron mass difference. We find that the behavior of the mixing amplitude is very complicated in the spacelike region and quite sensitive to the proton fraction of nuclear medium and nuclear density. In particular, in neutron rich nuclei (like Pb) and/or neutron stars the mixing amplitudes become about 10 $\sim$ 100 times as large as those in typical mirror nuclei.

Extraction of Inelastic Mecahnical Properties of Metals from Indentation Data

description: This work presents a detailed investigation into a methodology involving iterative finite element method (FEM) modelling of the indentation procedure, aimed at obtaining well defined mechanical properties of metals solely from experimental indentation data. Relatively large (1 2 mm radius) spherical indenters have been used which offer a number of advantages. The material properties must conform to an analytical constitutive law and part of the challenge of this type of work is to converge efficiently on the best fit set of values for the variables in this law. Comprehensive comparisons are made between outcomes of these procedures and properties obtained via conventional uniaxial testing. It is demonstrated that it is possible to extract the stress strain behaviour of metals that compare well with the macroscopically measured properties using an instrumented indentation load displacement plot, as long as the penetration ratio, δ/R, is approximately 40 %. The required penetration ratio to converge on the residual indent profile is much smaller which has significant benefits. Both of these approaches are applied to a coating system consisting of a sprayed superalloy overlayer (~2.5 mm thick) on a single crystal superalloy substrate (2.5 mm thick), in as received and annealed conditions. Time dependent creep properties were also investigated using recess instrumented indentation. This technique uses a pre machined spherical cap recess with the same radius as the indenter to ensure that the stresses during indentation do not exceed the yield stress. Indentation inferred properties compared well with those obtained from macroscopic (compression) uniaxial tests.

HST/STIS Spectroscopy of the Optical Outflow from DG Tau: Indications for Rotation in the Initial Jet Channel

description: We have carried out a kinematical, high angular resolution (~ 0".1) study of the jet from DG Tau within 0."5 from the source (or 110 AU along this flow). We analysed line profiles extracted from a set of seven spectra taken with STIS on board the Hubble Space Telescope, with the slits parallel to the jet axis but displaced transversely every 0".07. For the flow of moderate velocity (-70 km/s), we have found systematic differences in the radial velocities of lines emitted on alternate sides of the jet axis. The results are corrected for the effects due to uneven illumination of the slit. The relative Doppler shifts range from 5 to 20 km/s. If this is interpreted as rotation, the flow is then rotating clockwise looking from the jet towards the source and the derived toroidal velocities are in the range 6 - 15 km/s. Using recent estimates of the mass loss rate, one obtains for the considered velocity regime, an angular momentum flux of ~ 3.8x10E-5 M_sun/yr AU km/s. Our findings may constitute the first detection of rotation in the initial channel of a jet flow. The derived values appear to be consistent with the predictions of popular magneto-centrifugal jet-launching models, although we cannot exclude transverse outflow asymmetries other than rotation.

description: Inhalation exposure chambers may be used for in vivo drug delivery or toxicological assessments among other applications. Nose-only exposure chamber (NOEC) systems limit non-respiratory aerosol exposure pathways that may affect biological response analyses in mice. Uniform aerosol delivery between all ports is desired, but any exposure system design may introduce variability. The aerosol flow characteristics in a commercially available NOEC system were assessed computationally and experimentally to estimate the particle size-dependent non-uniformities of the aerosol sampled at each exposure port. Only dilute non-evolving aerosols are considered in the present study. The experimental measurements recorded a flow velocity variability of up to 20% between ports. Sampling variability between ports was experimentally verified to be within 10% for particles >0.56 µm and <1.7 µm at controlled velocity dictated by the animal’s respiratory flow rate. This smaller particle number density variability at the exposure port was also predicted computationally. Main source of flow variability was associated to a recirculation inside the inner plenum. Sedimentation of larger particles (>3 µm) was observed inside the ports, causing visible aerosol separation on the top of the channel delivering the aerosol to the exposure trumpet. As the effect was minor and applied to particles beyond the size range recommended for mouse inhalation studies, it should have no influence on the dosimetry of inhaled aerosols. In the range of aerosol particle sizes and flow rates considered, a good agreement between computational and experimental results was found, confirming the suitability of the system for mouse inhalation studies, and the insights obtained may give rise to further improvements in the system design.
A Condensed Constrained Nonconforming Mortar-based Approach for Preconditioning Finite Element Discretization Problems

description: This paper presents and studies an approach for constructing auxiliary space preconditioners for finite element problems using a constrained nonconforming reformulation, that is based on a proposed modified version of the mortar method. The well-known mortar finite element discretization method is modified to admit a local structure, providing an element-by-element or subdomain-by-subdomain assembly property. This is achieved via the introduction of additional trace finite element spaces and degrees of freedom (unknowns) associated with the interfaces between adjacent elements or subdomains. The resulting nonconforming formulation and a reduced via static condensation Schur complement form on the interfaces are used in the construction of auxiliary space preconditioners for a given conforming finite element discretization problem. The properties of these preconditioners are studied and their performance is illustrated on model second order scalar elliptic problems utilizing high order elements.

description: We suggest that explaining privacy behaviors requires understanding not only individual attitudes, but also norms and trust. We propose: (1) the popularity of a potentially privacy-violating technology leads individuals to expect that others approve of privacy violations and simultaneously increases their trust in the technology provider; (2) the frequency of privacy violations by other similar providers leads individuals to expect that a specific provider will engage in privacy-violating behaviors and decreases trust in that provider; (3) trust in a specific provider and expectations that others approve of the provider violating users’ privacy increase, and expectations that other similar providers are likely to violate privacy decrease, willingness to use a technology. We test our propositions using two vignette experiments in the context of a household energy app. Our results are generally consistent with our hypotheses. Our findings have implications for understanding privacy norms and highlight the potential consequences of major technology roll-outs.

description: We analyze the entanglement of SU(2)-invariant density matrices of two spins $\vec S_{1}$, $\vec S_{2}$ using the Peres-Horodecki criterion. Such density matrices arise from thermal equilibrium states of isotropic spin systems. The partial transpose of such a state has the same multiplet structure and degeneracies as the original matrix with eigenvalue of largest multiplicity being non-negative. The case $S_{1}=S$, $S_{2}=1/2$ can be solved completely and is discussed in detail with respect to isotropic Heisenberg spin models. Moreover, in this case the Peres-Horodecki ciriterion turns out to be a sufficient condition for non-separability. We also characterize SU(2)-invariant states of two spins of length 1.

description: From archived and recent high speed photometry of VW Hyi we find Dwarf Nova Oscillations (DNOs) occasionally present throughout outburst, evolving from 14.06 s period at maximum to > 40 s near the end of outburst. A relatively slow increase of period is followed by rapid increase and subsequent decrease. Quasi-periodic Oscillations (QPOs) are seen at periods of hundreds of seconds. For the first time, an evolution of QPO period is seen, steadily increasing during the final decline of an outburst. The occasional presence of two DNOs, separated in frequency by the QPO frequency, suggests reprocessing of the rotating DNO beam by a `wall' rotating progradely in the disc at the QPO period.

description: The development of CdZnTe detectors with an orthogpnal coplanar anode structure has important implications for future astrophysical instrumentation. As electron-only devices, like pixel detectors, coplanar anode strip detectors can be fabricated in the thickness required to be effective for photons with energies in excess of 500 keV. Unlike conventional double-sided strip detectors, the coplanar anode strip detectors require segmented contacts and signal processing electronics on only one surface. This facilitates the fabrication of closely-packed large area arrays that will be required for the next generation of coded aperture imagers. These detectors provide both very good energy resolution and sub-millimeter spatial resolution (in all three spatial dimensions) with far fewer electronic channels than are required for pixel detectors. Here we summarize results obtained from prototype detectors having a thickness of 5 mm and outline a concept for large area applications.

An investigation into the prevalence, impact and management of cancer-related fatigue in teenage and young adult patients

Teenage and young adult

description: Teenage and young adult (TYA) cancer patients describe debilitating fatigue. The impact of fatigue is particularly detrimental at this age because it hinders key developmental needs, such as independence. Although exercise and psychological treatments are the most effective management approaches in older adults, TYAs have unique healthcare needs and research findings cannot be extrapolated to younger patients. The aim of this programme of research was to increase understanding of cancer-related fatigue (CRF) in TYAs, in order to develop a non-pharmacological fatigue intervention. Three multimethod studies have been conducted, underpinned by self-efficacy theory. 1) A systematic literature review synthesised existing research evidence. 2) A multicentre electronic survey evaluated the experience of TYA CRF and its current management across the UK. 3) A multiphase, longitudinal, qualitative study, involving patient-parent dyads, has led to the co-design of a fatigue intervention. This work has confirmed that fatigue is the most prevalent and distressing symptom experienced by TYAs with cancer, and is an independent predictor of poor quality of life. Fatigue persists long after the end of cancer treatment, perpetuated by vicious cycles of emotional and behavioural responses to the symptom. Cognitive fatigue has a particularly negative impact and influences the ability to work, be in education or socialise. Parents also experience adverse consequences, including fatigue-related interpersonal tensions. Despite the enormity of the problem, fatigue is currently inadequately managed. TYAs described extensive, age-related intervention needs, including a preference for videos over written information. The co-designed intervention is predominantly cognitive in approach with, for example, mindfulness techniques being more acceptable than energy conservation. TYAs require structured activity support, given the physical reserve of youth and fear that activity may worsen fatigue. Young patients have inspired, and helped drive, this programme of work. Engagement with the research process was high, and participants embraced the innovative research methods. Information has been generated that will optimise the design of the future definitive trial to test intervention effectiveness.

The electrical properties of the junctions are studied individually and collectively using statistical tools to extract correlations between device geometries and electrical data. The dissertation includes discussion of the theory of relevant electronic transport including numerical simulations. Several initiated projects deriving from this work are introduced. A second device reported in this thesis is a memristive switch. Contacting thin films of Al2O3 with graphene delivered junctions which exhibit memristive behaviour with an ultrahigh on-oﬀ conductance ratio. The conduction state of the junctions is correlated with morphological changes in the devices, whereby conductive flament formation in the junction is found to lead to electrically-controllable and reversible gas encapsulation in bubbles in the structure. The device is measured electrically and topographically, and the correlation between the two aspects is studied. A discussion of memristive conduction is included with numerical simulations. A third section reports on a project studying thermoelectricity in self-assembled molecular junctions, as they show potential for improved thermoelectric efficiency for energy harvesting; this is discussed in the dissertation. Strategies to benchmark the studies are presented with relevant devices fabricated and measured. These include the development of a measurement protocol to study thermoelectricity in devices, studies of electrical coupling between various molecular structures and graphene electrodes, molecular-structure dependence of electrical and thermal conductance of junctions. Preliminary results and on-going work are discussed.

description: The most general renormalizable interaction between the Higgs sector and a new gauge-singlet scalar $S$ is governed by two interaction terms: cubic and quartic. The quartic interaction is only loosely constrained by invisible Higgs decays. Given current experimental limits about $10\%$ of all Higgs bosons created at the LHC can be converted to new scalars with the mass up to $m_{\rm Higgs}/2$. This can significantly extend the reach of the LHC-based Intensity Frontier experiments. We analyze the sensitivity of the FASER experiment to this model and discuss modest changes in the FASER 2 design that would allow to explore an orders-of-magnitude wider part of the Higgs portal's parameter space.

description: By studying the space of geodesics in $ADS_3/CFT_2$ and quantizing the geodesic motion, we relate scattering data to boundary entanglement of the CFT vacuum. The basic idea is to use a family of plane waves parametrized by coordinates of the space of geodesics i.e. kinematic space. This idea enables a simple calculation of the Berry curvature living on kinematic space. As a result we recover the Crofton form with a coefficient depending on the scattering energy. In arriving at these results the space of horocycles is used. We show that this new space used in concert with kinematic space incorporates naturally the gauge degrees of freedom responsible for an analogue of Berry's Phase. Horocycles also give a new geometric look to the strong subadditivity relation in terms of lambda lengths giving rise to shear coordinates of geodesic quadrangles. A generalization for geodesic polygons then reveals an interesting connection with $A_{n}$ cluster algebras. Here the cluster variables are the lambda lengths related to the regularized entropies of the boundary via the Ryu-Takayanagi relation. An elaboration of this idea indicates that cluster algebras might provide a natural algebraic means for encoding the gauge invariant entanglement patterns of certain boundary entangled states in the geometry of bulk geodesics. Finally using the language of integral geometry we show how certain propagators connected to the bulk, boundary and kinematic spaces are related to data of elementary scattering problems. We also present some hints how these ideas might be generalized for more general holographic scenarios.

Detecting dark matter substructure spectroscopically in strong gravitational lenses

description: The Cold Dark Matter (CDM) model for galaxy formation predicts that a significant fraction of mass in the dark matter haloes that surround L L* galaxies is bound in substructures of mass 1E4-1E7Msun. The number of observable baryonic substructures (such as dwarf galaxies and globular clusters) falls short of these predictions by at least an order of magnitude. We present a method for searching for substructure in the haloes of gravitational lenses that produce multiple images of QSOs, such as 4-image Einstein Cross lenses. Current methods based on broadband flux ratios cannot cleanly distinguish between substructure, differential extinction, microlensing and, most importantly, ambiguities in the host lens model. These difficulties may be overcome by utilizing the prediction that when substructure is present, the magnification will be a function of source size. QSO broad line and narrow line emission regions are approximately ~1pc and >100pc in size, respectively. When narrow line region (NLR) features are used as a normalisation, the relative intensity and equivalent width of broad line region (BLR) features will respectively reflect substructure-lensing and microlensing effects. Spectroscopic observations of just a few image pairs would probably be able to cleanly extract the desired substructure signature and distinguish it from microlensing. In the rest-optical, the Hbeta/[OIII] region is ideal, since the narrow wavelength range also largely eliminates differential reddening problems. Simulations of Q2237+030 are done as an example to determine the level of substructure that is detectable in this way, and possible systematic difficulties are discussed. This is an ideal experiment to be carried out with near-infrared integral field unit spectrographs on 8-m class telescopes.

description: Background and objectives. Autofluorescence imaging (AFI) is mainly used to detect (pre)cancerous colorectal and pulmonal lesions. This is the first report establishing the feasibility of AFI in patients with peritoneal carcinomatosis (PC). Methods. This is a prospective analysis of 10 patients undergoing conventional white-light laparoscopy (WL) and AFI for PC of different gastrointestinal tumors and 1 ovarian cancer. Before taking biopsies, suspicious peritoneal lesions were first detected by WL and then investigated by AFI. The intraoperative findings were photographed and then correlated with histological results. Results. Conventional WL and AFI evaluation was successful in all patients. A total of 38 biopsies were taken. The neoplasm detection rate under WL was 66% and increased to 86% when using AFI. The positive tumor detection rate was slightly higher in low AF lesions (83 vs 88%) and higher in tumor nodules (94%) than in flat peritoneal lesions (75%). For tumor nodules, the sensitivity was 94%, and the specificity was 100%. For flat lesions, the sensitivity was 75% and specificity 50%. Conclusions. We demonstrate the feasibility and effectiveness of AFI in patients with PC.

description: We report on a precise measurement of the electron-antineutrino angular correlation ($a$ coefficient) in free neutron beta-decay from the $a$SPECT experiment. The $a$ coefficient is inferred from the recoil energy spectrum of the protons which are detected in 4$π$ by the $a$SPECT spectrometer using magnetic adiabatic collimation with an electrostatic filter. Data are presented from a 100 days run at the Institut Laue Langevin in 2013. The sources of systematic errors are considered and included in the final result. We obtain $a = -0.10430(84)$ which is the most precise measurement of the neutron $a$ coefficient to date. From this, the ratio of axial-vector to vector coupling constants is derived giving $|λ| = 1.2677(28)$.

description: Glioblastoma multiforme (GBM) is the most malignant and common primary brain cancer in adults, with a 2.5-year survival of only $~$8%. In this single case study we have analysed the development of a primary GBM over four years. We performed WGS and RNAseq on three, spatially distinct samples of the treatment naïve primary tumour, the first recurrence and the fatal second recurrence. We observed a massive increase in mutations from the first to the second recurrence, showing predominantly C$>$T and A$>$G transitions, which is a pattern typical of TMZ treatment. The fact that the hypermutation did not appear until the second recurrence raises questions about the mechanism of hypermutation. The therapeutic apoptotic action of TMZ relies on the function of the mismatch repair (MMR) pathway. In the second recurrence we observed disruptive mutations of MSH6, MSH2, PMS2 and MLH1 all of which are crucial to the MMR pathway. The pattern of mutations of these genes varied between the samples taken from the second recurrence, however, all three samples showed hypermutation. This suggests that the hypermutation observed after TMZ treatment only occurs if the MMR is damaged, but that this damage does not need to be at a specific locus. Using the CRISPR-Cas9 technology we explored the impact of MMR mutations on patient derived GBM cell lines. Results on MSH2 and MSH6 knockout cell lines treated with TMZ showed the reproduction of the hypermutation phenotype in vitro, but only in MGMT promoter methylated cell lines. Moreover, the DNA analysis of the patient showed one shared mutation in high copy number in all of the nine samples: a mutation in EGFR G598V. We hypothesise that subsequent tumours developed from an original clone bearing this mutation. This mutated oncogene is located on an extrachromosomal circular DNA structure known as a double minute (DM), which is found in an estimated 40$%$ of GBM. We performed linked-read sequencing using the 10X Genomics Chromium technology to reconstruct the DM and shed light on its emergence.
