description: Since Purcell's seminal report 75 years ago, electromagnetic resonators have been used to control light-matter interactions to make brighter radiation sources and unleash unprecedented control over quantum states of light and matter. Indeed, optical resonators such as microcavities and plasmonic nanostructures offer excellent control but only over a limited spectral range. Strategies to tune both emission and the resonator are often required, which preclude the possibility of enhancing multiple transitions simultaneously. In this letter, we report a more than 590-fold radiative emission enhancement across the telecommunications emission band of Erbium-ions in silica using a single non-resonant plasmonic waveguide. Our plasmonic waveguide uses a novel reverse nanofocusing approach to efficiently collect emission, making these devices brighter than all non-plasmonic control samples considered. Remarkably, the high broadband Purcell factor allows us to resolve the Stark-split electric dipole transitions, which are typically only observed under cryogenic conditions. Simultaneous Purcell enhancement of multiple quantum states is of interest for photonic quantum networks as well as on-chip data communications.

Exhaled breath condensate based breath analyser

Publisher: name: Imperial College London
Year: 2020

description: Exhaled breath condensate (EBC) based breath analysis has gained significant interest in pulmonary disease diagnostics over the past few years due to the non-invasiveness and simplicity of the technique. Most approaches to date have separated EBC collection from the subsequent lab-based analysis, more notably, integrated EBC collector and analyser do not exist. Under current suggested protocol EBC samples for hydrogen peroxide analysis needs freezing at -70 C immediately after collection but still exhibit instabilities in concentration. To address those difficulties and to provide easy-to-use devices for patients, we have proposed a portable integrated EBC analyser, which gives measurement results within 3 minutes. The device incorporates Peltier cooling for sample collection; electronics control system and a disposable chemically modified amperometric sensor. Cooling system and device architecture were designed based on thermofluidic analysis of Falkner-Skan solution. Theoretical modelling and experimental evidence suggest that previously reported large variations between analyte concentrations arise from poor control of the condensation process. Fundamental studies suggest higher condensation temperature favours more concentrated analyte collection, relieving the burden on electrochemical sensor limit of detection (LOD). Low hydrogen peroxide in EBC presents another challenge. We have developed a modified Prussian blue (PB) sensor, by blending PB in conducting polymer matrix to increase PB density on electrode as well as cross linking matrix to improve the mechanical properties and enhance processability. Full mechanistic investigation using rotation disk electrode and chronoamperometry experiments reveal the kinetics of the sensor and informed subsequent development. The sensor has been demonstrated to measure hydrogen peroxide in EBC.

On a linear fused Gromov-Wasserstein distance for graph structured data

description: We present a framework for embedding graph structured data into a vector space, taking into account node features and topology of a graph into the optimal transport (OT) problem. Then we propose a novel distance between two graphs, named linearFGW, defined as the Euclidean distance between their embeddings. The advantages of the proposed distance are twofold: 1) it can take into account node feature and structure of graphs for measuring the similarity between graphs in a kernel-based framework, 2) it can be much faster for computing kernel matrix than pairwise OT-based distances, particularly fused Gromov-Wasserstein, making it possible to deal with large-scale data sets. After discussing theoretical properties of linearFGW, we demonstrate experimental results on classification and clustering tasks, showing the effectiveness of the proposed linearFGW.

description: WRF model version 4.0.1 was used to produce a 32 yr high-resolution downscaling climatology over Santa Barbara County. WRF was configured with 4 two-way nested grids with 27 km, 9 km, 3 km and 1 km horizontal grid spacings. WRF was configured with 55 vertical levels and model top at 50 hPa. The configuration used numerical parameterizations for microphysics (Single moment 6-class, Hong and Lim, 2006), long-wave and short-wave radiation transfer (RRTMG, Iacono et al., 2008), Noah multi-parameterization options (Noah-MP) (Niu et al., 2011), surface layer physics and planetary boundary layer (MYNN, Nakanishi and Niino, 2009; Olson et al., 2019). Initial and boundary conditions were obtained from the European Centre for Medium-Range Weather Forecasts Interim Reanalysis (ERA Interim) (Dee et al., 2011). WRF was initialized on 1 July 00UTC of a given year and integrated continuously until 1 September 00UTC of the following year and repeated for 32 yr. Sea surface temperature (SST) from ERA Interim was updated every 6 h. Grid nudging was applied in all model levels of the 27 km grid (nudging coefficient 0.0003 s−1) so that WRF was forced to follow large-scale features from the reanalysis.

description: Unsaturated periporomechanics is a strong nonlocal poromechanics based on peridynamic state and effective force concept. In the previous periporomechnics the total Lagrangian formulation is adopted for the solid skeleton of porous media. In this article as a new contribution we formulate and implement an updated Lagrangian unsaturated periporomechanics framework for modeling extreme large deformation in unsaturated soils under drained condition, e.g., soil column collapse. In this new framework the so-called bond-associated sub-horizon concept is utilized to enhance the stability and accuracy at extreme large deformation of solid skeleton. The stabilized nonlocal velocity gradient in the deformed configuration is used to update the effective force state from a critical state based visco-plastic model for unsaturated soils. The updated Lagrangian periporomechanics is implemented numerically through an explicit Newmark scheme for high-performance computing. Numerical examples are presented to demonstrate the efficacy of the updated Lagrangian periporomechanics and its robustness in modeling unsaturated soil column collapse under drained condition.

description: La2Ni7 is an intermetallic compound that is thought to have itinerant magnetism with a small moment ordering below 65 K. A recent study of single crystal samples by Ribeiro et. al. [Phys. Rev. B 105, 014412 (2022)] determined detailed anisotropic H-T phase diagrams and revealed three zero-field magnetic phase transitions at T1 ~ 61.0 K, T2 ~ 56.5K, and T3 ~ 42 K. In that study only the highest temperature phase is shown to have a clear ferromagnetic component. Here we present a single crystal neutron diffraction study determining the propagation vector and magnetic moment direction of the three magnetically ordered phases, two incommensurate and one commensurate, as a function of temperature. The higher temperature phases have similar, incommensurate propagation vectors, but with different ordered moment directions. At lower temperatures the magnetic order becomes commensurate with magnetic moments along the c direction as part of a first-order magnetic phase transition. We find that the low-temperature commensurate magnetic order is consistent with a proposal from earlier DFT calculations.

Genetic screens identify novel liabilities of senescent cells
Creators: name: McHugh, Domhnall Seamus
Publisher: name: Imperial College London
Year: 2020

description: Drugs that selectively kill senescent cells, senolytics, can improve the outcomes of cancer, fibrosis and age-related diseases. Despite their potential, our knowledge of the molecular pathways that affect the survival of senescent cells is limited. To identify novel senolytic targets, we performed RNAi and CRISPR screens and identified COPI (Coatomer Complex I)vesicle formation as a liability of senescent cells. Genetic or pharmacological inhibition ofCOPI results in Golgi dispersal, intracellular accumulation of secreted factors, and unfolded protein response-dependent cell death of senescent cells. Knockdown of COPI subunits improves the outcomes of cancer and fibrosis in mouse models. Drugs targeting COPI have poor pharmacological properties, but N-myristoyltransferase inhibitors (NMTi) phenocopy COPI inhibition and are potent senolytics. NMTi eliminate senescent cells, ameliorating lung fibrosis and liver steatosis in aged mice. Our results suggest that senescent cells rely on a hyperactive secretory apparatus, and that inhibiting trafficking kills senescent cells in various senescence-associated diseases and during ageing.

description: Machine-vision-based defect classification techniques have been widely adopted for automatic quality inspection in manufacturing processes. This article describes a general framework for classifying defects from high volume data batches with efficient inspection of unlabelled samples. The concept is to construct a detector to identify new defect types, send them to the inspection station for labelling, and dynamically update the classifier in an efficient manner that reduces both storage and computational needs imposed by data samples of previously observed batches. Both a simulation study on image classification and a case study on surface defect detection via 3D point clouds are performed to demonstrate the effectiveness of the proposed method.

description: The growing experimental indication of Lepton Flavour Universality Violation (LFUV) both in charged- and neutral-current semileptonic B-decays, has triggered many theoretical interpretations of such non-standard phenomena. Focusing on popular scenarios where the explanation of these anomalies requires New Physics at the TeV scale, we emphasise the importance of including electroweak corrections to obtain trustable predictions for the models in question. We find that the most important quantum effects are the modifications of the leptonic couplings of the W and Z vector bosons and the generation of a purely leptonic effective Lagrangian. As a result, the tight experimental bounds on Z-pole observables and tau decays challenge an explanation of the current non-standard data. We illustrate how these effects arise, by providing a detailed discussion of the running and matching procedure which is necessary to derive the low-energy effective Lagrangian.

description: We present the large statistics of the galaxy effective radius in the rest-frame far-infrared (FIR) wavelength Re(FIR) obtained from 1627 deep ALMA 1-mm band maps that become public by 2017 July. Our ALMA sample consists of 1034 sources at z=0-6 that typically have the star-formation rate of ~100-1000 M$_{\odot}$/yr and the stellar mass of ~10$^{10}$-10$^{11.5}$ M$_{\odot}$. We homogeneously derive Re(FIR) and FIR luminosity L_FIR of our ALMA sources via the same uv-visibility method with the exponential disk fitting, carefully evaluating the selection and measurement incompletenesses by realistic Monte-Carlo simulations. We find that there is a positive correlation between Re(FIR) and L_FIR at the >99% significance level. The best-fit power-law function, Re(FIR) $\propto$ L_FIR$^α$, provides $α=0.28+/-0.07$, and shows that the average Re(FIR) at a fixed L_FIR decreases toward high redshifts. The best-fit $α$ and the redshift evolution of Re(FIR) are similar to those of the galaxy effective radius in the rest-frame UV (optical) wavelength Re(UV) (Re(Opt.)) revealed by Hubble Space Telescope (HST) studies. We identify that our ALMA sources have significant trends of Re(FIR)

Proximal Policy Optimization with Adaptive Threshold for Symmetric Relative Density Ratio

Subjects: subject: Machine Learning (cs.LG)
subject: FOS: Computer and information sciences

description: Deep reinforcement learning (DRL) is one of the promising approaches for introducing robots into complicated environments. The recent remarkable progress of DRL stands on regularization of policy, which allows the policy to improve stably and efficiently. A popular method, so-called proximal policy optimization (PPO), and its variants constrain density ratio of the latest and baseline policies when the density ratio exceeds a given threshold. This threshold can be designed relatively intuitively, and in fact its recommended value range has been suggested. However, the density ratio is asymmetric for its center, and the possible error scale from its center, which should be close to the threshold, would depend on how the baseline policy is given. In order to maximize the values of regularization of policy, this paper proposes a new PPO derived using relative Pearson (RPE) divergence, therefore so-called PPO-RPE, to design the threshold adaptively. In PPO-RPE, the relative density ratio, which can be formed with symmetry, replaces the raw density ratio. Thanks to this symmetry, its error scale from center can easily be estimated, hence, the threshold can be adapted for the estimated error scale. From three simple benchmark simulations, the importance of algorithm-dependent threshold design is revealed. By simulating additional four locomotion tasks, it is verified that the proposed method statistically contributes to task accomplishment by appropriately restricting the policy updates.

description: Translation of perceptual soundscape attributes from one language to another remains a challenging task that requires a high degree of fidelity in both psychoacoustic and psycholinguistic senses across the target population. Due to the inherently subjective nature of human perception, translating soundscape attributes using only small focus group discussion or expert panels could lead to translations with psycholinguistic meanings that, in a non-expert setting, deviate or distort from that of the source language. In this work, we present a quantitative evaluation method based on the circumplex model of soundscape perception to assess the overall translation quality across a set of criteria. As an initial application domain, we demonstrated the use of the quantitative evaluation framework in the context of an English-to-Thai translation of soundscape attributes.

description: We present electrical and thermal transport measurements in single crystals of the metallic oxide RuO$_2$. The resistivity and Seebeck coefficient measured up to 970K confirm the metallic nature of transport. Magnetoresistance and Hall effect measurements as a function of orientation can be most easily described by a multiband transport model. We find that the ordinary Hall effect dominates any anomalous Hall signal in single crystals.

description: We study the Ginzburg-Landau equations on line bundles over non-compact Riemann surfaces with constant negative curvature. We prove existence of solutions with energy strictly less than that of the constant curvature (magnetic field) one. These solutions are the non-commutative generalizations of the Abrikosov vortex lattice of superconductivity. Conjecturally, they are (local) minimizers of the Ginzburg-Landau energy. We obtain precise asymptotic expansions of these solutions and their energies in terms of the curvature of the underlying Riemann surface. Among other things, our result shows the spontaneous breaking of the gauge-translational symmetry of the Ginzburg-Landau equations.

description: Using muon spin rotation it is shown that the field of first flux penetration H_entry in Nb is enhanced by about 30% if coated with an overlayer of Nb_3Sn or MgB_2. This is consistent with an increase from the lower critical magnetic field H_c1 up to the superheating field H_sh of the Nb substrate. In the experiments presented here coatings of Nb_3Sn and MgB_2 with a thickness between 50 and 2000nm have been tested. H_entry does not depend on material or thickness. This suggests that the energy barrier at the boundary between the two materials prevents flux entry up to H_sh of the substrate. A mechanism consistent with these findings is that the proximity effect recovers the stability of the energy barrier for flux penetration, which is suppressed by defects for uncoated samples. Additionally, a low temperature baked Nb sample has been tested. Here a 6% increase of H_entry was found, also pushing H_entry beyond H_c1.

description: We study the statistical properties of an ensemble of weak gravitational waves interacting nonlinearly in a flat space-time. We show that the resonant three-wave interactions are absent and develop a theory for four-wave interactions in a reduced case of a diagonal metric tensor. In this limit, where only one type of gravitational waves are present, we derive the interaction Hamiltonian and consider the asymptotic regime of weak gravitational wave turbulence. Both direct and inverse cascades are found for the energy and the wave action respectively, and the corresponding wave spectra are derived. The inverse cascade is characterized by a finite-time propagation of the metric excitations - a process similar to an explosive non-equilibrium Bose-Einstein condensation, which provides an efficient mechanism to ironing out small-scale inhomogeneities. The direct cascade leads to an accumulation of the radiation energy in the system. These processes might be important for understanding the early Universe where a background of weak nonlinear gravitational waves is expected.

description: Objetivo: Identificar los principales factores que inciden en la actitud hacia la donación de órganos en adultos de 50 a 60 años en Zacatecas. Método: Se realizó un estudio analítico descriptivo de cohorte transversal. La población fue integrada por 155,000 adultos de entre 50 a 60 años que viven en Zacatecas, 383 participantes conformaron la muestra seleccionados con un muestreo por bola de nieve. Se elaboró un cuestionario con dos encuestas de diferentes autores, del centro estatal de trasplantes de Tamaulipas (2015) y la realizada por Melisa Sánchez (2015). Resultados: En relación a la actitud de las personas, respecto a la pregunta de si donaría sus órganos en vida se obtuvo que solo el 43.3% lo haría, mientras que el 40% tenía dudas y solo el 16.7% no lo haría, siendo la principal causa el miedo a que les pase algo, mientras que al evaluar que tan informada esta la población, se encontró que el 73.3% cree que es poca la información que existe sobre el tema de la donación y trasplantes de órganos en Zacatecas, el 33.3% de la población encuestada posee una escasa información respecto a la donación de órganos. Conclusión: Los factores como la falta de información y las creencias religiosas no inciden en la actitud ante la donación de órganos en adultos de 50 a 60 años, esto refleja que la información con la que se cuente en base a la donación de órganos no influirá en la toma de decisión para la donación.

description: Objetivo: Determinar la Calidad de vida de los universitarios tanto docentes y estudiantes durante la pandemia Covid 19 en Zacatecas. Método: Se realizó un estudio descriptivo, de cohorte transversal. La muestra estuvo conformada por 185 participantes, docentes y estudiantes de una Universidad de Zacatecas.Resultados: Las dimensiones mejor evaluadas y que estuvieron por encima de la media que es de 50 fueron: función física, rol físico (solo en el caso de los alumnos), salud mental, vitalidad y dolor corporal. En contraparte, estuvieron el rol emocional que es de 26.2 en docentes y en alumnos 34.2 y en el caso de función social para los alumnos fue una media de 40.0. Conclusión: La calidad de vida en 4 de las 8 dimensiones se encuentran evaluadas por encima de la media, conforme a estos resultados es importante indicar que existió coherencia o correspondencia entre las dimensiones función física y rol físico ya que el grado de limitación para hacer actividades físicas no interfirió en el trabajo y otras actividades diarias. Mientras tanto, en el rol emocional el resultado mostró que presentaron problemas de tipo emocional como nerviosismo, tristeza o bien ha interferido en sus actividades cotidianas.

description: We propose and analyze a deterministic mathematical model for the transmission of food-borne diseases in a population consisting of humans and flies. We employ the Caputo operator to examine the impact of governmental actions and online food delivery services on the transmission of food-borne diseases. The proposed model investigates important aspects such as positivity, boundedness, disease-free equilibrium, basic reproduction number and sensitivity analysis. The existence and uniqueness of a solution for the initial value problem is established using Banach and Schauder type fixed point theorems. Functional techniques are employed to demonstrate the stability of the proposed model under the Hyers-Ulam condition. For an approximate solution, the iterative fractional order Predictor-Corrector scheme is utilized. The simulation of this scheme is conducted using Matlab as the numeric computing environment, with various fractional order values ranging from 0.75 to 1. Over time, all compartments demonstrate convergence and stability. The numerical simulations highlight the necessity for the government to implement the most effective food safety control interventions. These measures could involve food safety awareness and training campaigns targeting restaurant managers, staff members involved in online food delivery, as well as food delivery personnel.

Nonlinear modal analysis for blisks with friction dampers
Creators: name: Sun, Yekai
Publisher: name: Imperial College London
Year: 2020

description: Dynamic analyses of nonlinear systems have become an important topic in the field of turbomachinery. In industrial turbomachinery, the friction damping is regarded as the major damping source compared to the aerodynamic damping and material damping. Contact with friction is a type of common non-conservative and non-smooth nonlinearities. The existence of various friction joints in industrial turbomachinery makes the dynamic analysis complicated. The definition of the damped Nonlinear Normal Modes (dNNMs) and various numerical approaches facilitate the infrastructure of nonlinear modal analysis for structures with friction dampers. However, the relations between dNNMs and resonant solutions in forced responses cannot be directly addressed. In this context, the purpose of the present thesis is (i) to evaluate the performance of the existing numerical approaches for computing the dNNMs of systems with non-conservative nonlinearities; (ii) to develop a new method to directly relate the dNNMs to the resonant solutions in forced response for such system; and (iii) to study the geometric influence of the friction ring dampers on their dynamic responses and damping performances. The first contribution of the present thesis is to provide a comprehensive comparison of the existing numerical approaches, including Complex Nonlinear Mode (CNM) and Extended Periodic Motion Concept (EPMC). EPMC with artificial hysteretic damping is firstly attempted and compared with the original EPMC and CNM. The advantages and limitations of each method are critically discussed. The second contribution is the development of the Extended Energy Balance Method (E-EBM), which is a numerical method used to efficiently predict the resonances using the dNNMs of a non-conservative nonlinear system. This E-EBM can be simply applied to both CNM and EPMC approaches. The third contribution is the investigation the damping performance of friction ring dampers for blisk structures, especially the geometric effects of the ring dampers. The geometric design of the ring dampers is achieved by using kriging meta-modelling to predict the dNNMs. Useful advice is proposed for the future design of friction ring dampers.

description: Tests of gravity at the galaxy scale are in their infancy. As a first step to systematically uncovering the gravitational significance of galaxies, we map three fundamental gravitational variables -- the Newtonian potential, acceleration and curvature -- over the galaxy environments of the local universe to a distance of approximately 200 Mpc. Our method combines the contributions from galaxies in an all-sky redshift survey, halos from an N-body simulation hosting low-luminosity objects, and linear and quasi-linear modes of the density field. We use the ranges of these variables to determine the extent to which galaxies expand the scope of generic tests of gravity and are capable of constraining specific classes of model for which they have special significance. Finally, we investigate the improvements afforded by upcoming galaxy surveys.

description: Introducción: La literatura señala que la dinámica familiar influencia las prácticas y comportamientos para la alimentación de niños con autismo; sin embargo, existen vacíos para comprender esa influencia y sus consecuencias. Objetivo: Comprender la dinámica familiar en relación a las concepciones, prácticas y comportamientos de las familias para la alimentación del niño con autismo. Método:: Estudio cualitativo, de casos múltiples, descriptivo, realizado en el Sur de Brasil, entre agosto de 2018 y marzo de 2019, en dos instituciones que atienden a niños con autismo. Se realizaron entrevistas semiestructuradas, genogramas y ecomapas a nueve familias. Se utilizó la estrategia analítica de síntesis de casos cruzados, que fue apoyada por el software WebQDA. Resultados: Se identificaron tres categorías. La categoría “Concepciones, prácticas y comportamientos para la alimentación” expresa el significado, creencias, rutina y estrategias relacionadas con la alimentación. La segunda: “Organización de la dinámica familiar” explica la rutina, los roles y la relación familiar con el cuidado infantil. La tercera: “Percepción familiar del niño” se refiere a la comprensión y perspectiva familiar de la salud del niño. . Conclusiones: La alimentación al ser percibida como acto social permite a las familias organizar sus dinámicas, afrontar las dificultades de forma positiva y desarrollar acciones que promuevan prácticas y comportamientos alimentarios saludables, asociados a la red de apoyo social, organización de la familia, y avance del desarrollo y la autonomía del niño. El trabajo interprofesional se considera relevante para fortalecer la dinámica familiar, con acciones que impacten positivamente las prácticas y comportamientos de alimentación.

Advancing the synthesis of electronically functional materials in flow reactors

description: Conventional synthetic methods often give poor control over reaction conditions especially when applied to large quantity synthesis. Flow chemistry has been reported to provide a more con- trolled environment for synthesis and is particularly beneficial for the synthesis of functional ma- terials with properties that are sensitive to the reaction conditions. This thesis describes the development of several flow systems for the synthesis of electronically functional materials. An integrated flow system was developed for the preparation of the non-fullerene acceptor FBR is described. In addition to translating the two reaction steps to flow, the system also carries out in-line separation and solvent change in between the steps. In contrast to conventional batch conditions, the flow process dramatically reduced the reaction time from >12 hours down to 10 – 20 minutes. A separation procedure after the first step was able to isolate THF from aqueous base and simultaneously swapped the solvent from THF to toluene in preparation for carrying out the second reaction step. A complete flow system for synthesising P3HT polymer was also reported, including both monomer activation step and polymerisation. The system was able to produce P3HT polymer with high molecular weight (50.3 kDa) and low dispersity (1.20). The effect of changing the Grignard to monomer ratio on the polymer properties was investigated in detail. Additionally, in-line NMR spectroscopy analysis was employed in the flow system to provide near real-time analysis of the monomer activation step. Finally, the post-polymerisation functionalisation of the conjugated polymer F8BT-F with 4-methoxylthiophenol group was trans- lated to a flow reactor. The substitution reaction time was cut down to 30 minutes from >12 hours in batch.
