description: The paper establishes the result that solutions of the type described in the title of the article are only those that have been already presented in the literature. The procedure adopted in the paper is somewhat novel - while the usual practice is to display an exact solution and then to examine whether it is singularity free, the present paper discovers the conditions which a singularity free solution of the desired type must satistfy. There is no attempt to obtain exact solutions. Simply, the conditions that were ad-hoc introduced in the deduction of singularity free solutions are here shown to follow from the requirement of non-singularity.

description: The rapidly rotational motion of C$_{60}$ molecules provides us with an ingenious way to test Mashhoon's spin-rotation coupling. The spin-rotation coupling of electrons in the rotating C$_{60}$ molecule is considered in the present letter. It is shown that the intrinsic spin (gravitomagnetic moment) of the electron that can be coupled to the time-dependent rotating frequency of rotating frame of reference (C$_{60}$ molecule) results in a geometric phase, which may be measured through the electronic energy spectra of C$_{60}$ molecules.

description: Convective storms are one of the severe weather hazards found during the warm season. Doppler weather radar is the only operational instrument that can frequently sample the detailed structure of convective storm which has a small spatial scale and short lifetime. For the challenging task of short-term convective storm forecasting, 3-D radar images contain information about the processes in convective storm. However, effectively extracting such information from multisource raw data has been problematic due to a lack of methodology and computation limitations. Recent advancements in deep learning techniques and graphics processing units now make it possible. This article investigates the feasibility and performance of an end-to-end deep learning nowcasting method. The nowcasting problem was transformed into a classification problem first, and then, a deep learning method that uses a convolutional neural network was presented to make predictions. On the first layer of CNN, a cross-channel 3D convolution was proposed to fuse 3D raw data. The CNN method eliminates the handcrafted feature engineering, i.e., the process of using domain knowledge of the data to manually design features. Operationally produced historical data of the Beijing-Tianjin-Hebei region in China was used to train the nowcasting system and evaluate its performance; 3737332 samples were collected in the training data set. The experimental results show that the deep learning method improves nowcasting skills compared with traditional machine learning methods.

description: Based on online observations of fine particulate matter (PM2.5) for five consecutive years from January 2013 to December 2017 in Beijing, combined with simultaneous measurement of gaseous precursors and meteorological parameters, the evolution and meteorological causes of fine-particle explosive growth (FPEG) events were analyzed. During the 5-year observation period, 132 FPEG events were observed and these events were further divided into three types (3-, 6-, and 9-h events) according to their evolution duration. The majority of FPEG events were observed in winter under the conditions of higher gas precursor concentrations and unfavorable meteorological conditions. The average concentration of PM2.5 during winter FPEG events changed little from 2013 to 2016, whereas it decreased significantly in 2017, in accordance with the similar variation of gaseous species (SO2, NO2, and CO). In addition, the higher wind speeds and lowest relative humidity observed in 2017 were also conducive to the decrease in PM2.5. The evolutions of FPEG events and normal haze episodes were analyzed, revealing that the rate of increase in NO2 was much greater than that of SO2, suggesting more of a contribution from mobile sources than stationary sources. The polarPlot results suggest that the transportation from the southeast area of Beijing plays a major role in the formation of 3-h events, whereas local emissions is the main contributory factor for 9-h events and normal haze episodes. However, further quantitative analysis regarding the contributions of these factors is still needed.

description: Carbon atomic chain, linear benzene polymers, and carbon nanothreads are all one-dimensional (1D) ultrathin carbon structures. They possess excellent electronic and mechanical properties; however, their thermal transport properties have been rarely explored. Here, we systematically study their thermal conductance by combining the nonequilibrium Green's function and force field methods. The thermal conductance varies from 0.24 to 1.00 nW/K at 300 K, and phonon transport in the linear benzene polymers and carbon nanothreads is strongly dependent on the connectivity styles between the benzene rings. We propose a simple 1D model, namely force-constant model, that explains the complicated transport processes in these structures. Our study not only reveals intrinsic mechanisms of phonon transport in these carbon structures, but also provides an effective method to analyze thermal properties of other 1D ultrathin structures made of only several atomic chains.
title: Patient Reported Outcome Measures in Interventional Cardiology: Listen to the Patient
Creators: name: Kemp, I
Publisher: name: Liverpool John Moores University

description: Patient Reported Outcome Measures (PROMs) are instruments that seek patients’ views on symptoms, functional status and health related quality of life. My thesis analyses data from the Stent or Surgery Trial. A cohort of 988 patients completed several PROMs before, and at two time points after their revascularisation procedure, and this data forms the basis of my thesis. I found discordance between patients’ and their physicians with physicians slightly overstating angina burden prior to revascularisation and under reporting at twelve months post procedure by comparison to patients. I compared the generic EuroQol EQ-5D and disease specific Seattle Angina Questionnaire (SAQ) to assess the degree of agreement. I found the EQ-5D visual analogue scale (VAS) had poor correlation with any of the five domains of the SAQ. However, the VAS relates to how a patient feels at the time of completion and the SAQ refers to the previous four weeks. I then compared the full 19 question SAQ with a short 7 question version (SAQ-7). A single summary score was calculated for both instruments. Each timepoint showed a strong positive linear correlation above 0.9. The implication of this finding is there may be greater take-up for a PROM with fewer questions and that a single summary score is easier to understand. Finally, I examined some strengths and weaknesses of questionnaires. Advantages include expense, practicality, speed and anonymity. Disadvantages included user fatigue, dishonesty and bias in the way the questionnaire is designed. PROMs in the UK tend to be used to compare performance between individual operators or Trusts. In other countries such as Sweden they are used to calibrate individual patients’ treatment plans.
Front speed enhancement in cellular flows

description: The problem of front propagation in a stirred medium is addressed in the case of cellular flows in three different regimes: slow reaction, fast reaction and geometrical optics limit. It is well known that a consequence of stirring is the enhancement of front speed with respect to the non-stirred case. By means of numerical simulations and theoretical arguments we describe the behavior of front speed as a function of the stirring intensity, $U$. For slow reaction, the front propagates with a speed proportional to $U^{1/4}$, conversely for fast reaction the front speed is proportional to $U^{3/4}$. In the geometrical optics limit, the front speed asymptotically behaves as $U/\ln U$.

description: Everyday experience with centrifugal forces has always guided thinking on the close relationship between gravitational forces and accelerated systems of reference. Once spatial gravitational forces and accelerations are introduced into general relativity through a splitting of spacetime into space-plus-time associated with a family of test observers, one may further split the local rest space of those observers with respect to the direction of relative motion of a test particle world line in order to define longitudinal and transverse accelerations as well. The intrinsic covariant derivative (induced connection) along such a world line is the appropriate mathematical tool to analyze this problem, and by modifying this operator to correspond to the observer measurements, one understands more clearly the work of Abramowicz et al who define an ``optical centrifugal force'' in static axisymmetric spacetimes and attempt to generalize it and other inertial forces to arbitrary spacetimes. In a companion article the application of this framework to some familiar stationary axisymmetric spacetimes helps give a more intuitive picture of their rotational features including spin precession effects, and puts related work of de Felice and others on circular orbits in black hole spacetimes into a more general context.

description: Dissolved organic carbon (DOC) is the largest reduced carbon reservoir in modern oceans¹,². Its dynamics regulate marine communities and atmospheric CO₂ levels³,⁴, whereas ¹³C compositions track ecosystem structure and autotrophic metabolism⁵. However, the geologic history of marine DOC remains entirely unconstrained⁶,⁷, hindering our ability to mechanistically reconstruct coupled ecological and biogeochemical evolution. To address this, we developed the first direct proxy for past DOC signatures using co-precipitated organic carbon in iron ooids, and we applied this to 26 marine iron ooid-containing formations deposited over the past 1650 million years. Predicted DOC concentrations were near modern levels in the Paleoproterozoic then decreased by 90-99% in the Neoproterozoic before sharply rising in the Cambrian. We interpret these dynamics to reflect three distinct states: (i) small, single-celled organisms combined with severely hypoxic deep oceans; (ii) larger, more complex organisms and little change in oxygenation; (iii) continued organism growth and a transition to fully oxygenated oceans⁸,⁹. Furthermore, modern DOC is significantly ¹³C-enriched relative to the Proterozoic, likely due to changing autotrophic fractionation driven by biological innovation; together with isotopically invariant carbon inputs to Earth's surface¹⁰, this implies increasing relative organic carbon burial through time. Our results reveal new connections between the carbon cycle, ocean oxygenation, and the evolution of complex life.

We investigate the spin-rotation coupling and, by making use of Lewis-Riesenfeld invariant theory, we obtain exact solutions of the Schrödinger equation of a spinning particle in a time-dependent rotating reference frame. A potential application of these exact solutions to the investigation of Earth$^{,}$s rotating frequency fluctuation by means of neutron-gravity interferometry experiment is briefly discussed in the present paper.

Dataset Generation of Multi-Material Deformable Objects
Creators: name: Heckers, Sebastian
Publisher: name: ETH Zurich
Year: 2024

description: Traditional datasets, however, often rely on abstract, synthetic deformations that fail to capture the rich material properties influencing how objects behave under physical forces. This thesis addresses this limitation by introducing a novel dataset generation pipeline designed to create time-series data of multi-material deformable objects. The dataset encodes both geometric information and material-specific properties by simulating deformations in a physics-based environment using MuJoCo. The pipeline leverages the PartNet dataset and is processed into tetrahedral volume meshes, suitable for simulation, using advanced meshing techniques like fTetWild. These meshes are then modelled in MuJoCo and simulated to induce realistic deformations. The resulting dataset captures the time evolution of these deformations, providing a valuable resource for training and evaluating machine learning models aimed at material recognition and robotic interaction.

description: The polaron picture is employed to investigate and elucidate the physics of the two-qubit quantum Rabi model, which describes two identical qubits coupled to a common harmonic oscillator. This approach enables us to obtain the ground-state energy and some other simpler physical observables with high accuracy in all regimes of the coupling strengths $g$, while there is no constraint to the ration of tunneling frequency $Ω$ and field frequency $ω$, which is not simultaneously possible using previous methods. Besides, we also discover a new phenomenon which is not present in the one-qubit Rabi model: with the increase of coupling strength $g$, there is a transition of the ground state of the system from a multipolaron state to a bipolaron state. However, the tunneling frequency $Ω$ counteracts this process. Specifically, when tunneling frequency $Ω=0$, the system always stays in the bipolaron state.

description: High-speed laser frequency actuation is critical in all applications employing lasers and frequency combs, and is prerequisite for phase locking, frequency stabilization and stability transfer among multiple optical carriers. Soliton microcombs have emerged as chip-scale, broadband and low-power-consumption frequency comb sources.Yet, integrated microcombs relying on thermal heaters for on-chip actuation all exhibit only kilohertz actuation bandwidth. Consequently, high-speed actuation and locking of microcombs have been attained only with off-chip bulk modulators. Here, we present high-speed microcomb actuation using integrated components. By monolithically integrating piezoelectric AlN actuators on ultralow-loss Si3N4 photonic circuits, we demonstrate voltage-controlled soliton tuning, modulation and stabilization. The integrated AlN actuators feature bi-directional tuning with high linearity and low hysteresis, operate with 300 nW power and exhibit flat actuation response up to megahertz frequency, significantly exceeding bulk piezo tuning bandwidth. We use this novel capability to demonstrate a microcomb engine for parallel FMCW LiDAR, via synchronously tuning the laser and microresonator. By applying a triangular sweep at the modulation rate matching the frequency spacing of HBAR modes, we exploit the resonant build-up of bulk acoustic energy to significantly lower the required driving to a CMOS voltage of only 7 Volts. Our approach endows soliton microcombs with integrated, ultralow-power-consumption, and fast actuation, significantly expanding the repertoire of technological applications.

description: This paper presents a method for constrained motion planning from vision, which enables a robot to move its end-effector over an observed surface, given start and destination points. The robot has no prior knowledge of the surface shape, but observes it from a noisy point-cloud camera. We consider the multi-objective optimisation problem of finding robot trajectories which maximise the robot's manipulability throughout the motion, while also minimising surface-distance travelled between the two points. This work has application in industrial problems of \textit{rough} robotic cutting, \textit{e.g.} demolition of legacy nuclear plant, where the cut path need not be precise as long as it achieves dismantling. We show how detours in the cut path can be leveraged, to increase the manipulability of the robot at all points along the path. This helps avoid singularities, while maximising the robot's capability to make small deviations during task execution, \textit{e.g.} compliantly responding to cutting forces via impedance control. We show how a sampling-based planner can be projected onto the Riemannian manifold of a curved surface, and extended to include a term which maximises manipulability. We present the results of empirical experiments, with both simulated and real robots, which are tasked with moving over a variety of different surface shapes. Our planner enables successful task completion, while avoiding singularities and ensuring significantly greater manipulability when compared against a conventional RRT* planner.

description: The performance of face recognition (FR) systems applied in video surveillance has been shown to improve when the design data is augmented through synthetic face generation. This is true, for instance, with pair-wise matchers (e.g., deep Siamese networks) that typically rely on a reference gallery with one still image per individual. However, generating synthetic images in the source domain may not improve the performance during operations due to the domain shift w.r.t. the target domain. Moreover, despite the emergence of Generative Adversarial Networks (GANs) for realistic synthetic generation, it is often difficult to control the conditions under which synthetic faces are generated. In this paper, a cross-domain face synthesis approach is proposed that integrates a new Controllable GAN (C-GAN). It employs an off-the-shelf 3D face model as a simulator to generate face images under various poses. The simulated images and noise are input to the C-GAN for realism refinement which employs an additional adversarial game as a third player to preserve the identity and specific facial attributes of the refined images. This allows generating realistic synthetic face images that reflects capture conditions in the target domain while controlling the GAN output to generate faces under desired pose conditions. Experiments were performed using videos from the Chokepoint and COX-S2V datasets, and a deep Siamese network for FR with a single reference still per person. Results indicate that the proposed approach can provide a higher level of accuracy compared to the current state-of-the-art approaches for synthetic data augmentation.

description: Pyrite formation and burial in marine sediments decreases atmospheric CO2 and increases O2 levels. However, the sedimentological conditions that control pyrite burial remain poorly constrained, precluding quantitative reconstructions of sulphur cycle regulation on atmospheric compositions. Building on updated understanding of pyrite isotope dynamics, here we provide mechanistic insight by developing a non-dimensional diagenetic model that extracts the natural variables governing pyrite formation rates and sulphur isotopic compositions (δ34S values). Both properties are controlled by the local ratios of organic carbon content to sulphate concentration and organic carbon reactivity to sedimentation rate; formation rate is additionally sensitive to reactive iron delivery. Using only globally interpolated boundary values as inputs, our model accurately predicts signals recorded in a validation dataset of 216 sediment cores from diverse environmental settings across the modern ocean. Extrapolating this, we estimate a global pyrite burial flux of 7.0 × 10^12 mol S yr^-1 (sensitivity test range: 2.5 × 10^12 to 19.0 × 10^12 mol S yr^-1) with a weighted-average δ34S value of -4 ‰ VCDT (range: -8 to +3 ‰ VCDT). This flux is substantially larger than that of terrestrial pyrite oxidation (1.3 × 10^12 mol S yr^-1), indicating that the sulphur cycle is currently not in steady state, but rather described by net pyrite burial and thus atmospheric O2 accumulation. Finally, we utilise this model framework to invert the geologic pyrite δ34S record and assess changes in sedimentological properties and pyrite burial flux throughout the Phanerozoic Eon.

Creators: name: Condry, Ian
Publisher: name: ethnographiques.org
Year: 2020

description: Dans cet essai, Ian Condry trace un portrait de la globalisation de la culture populaire américaine. De prime abord, la musique hip-hop japonaise semble une illustration parfaite de la manière dont la culture populaire américaine envahit le monde. Mais un examen plus attentif révèle l'existence d'un processus dynamique par lequel la signification du hip-hop est réinterprétée pour s'ajuster au contexte japonais. En particulier, les artistes et les fans japonais assimilent les clubs de nuit aux genba, c'est-à-dire aux « véritables lieux » du hip-hop local. Ces clubs bruyants, bondés, enfumés et ouverts jusqu'au petit matin offrent un aperçu des activités quotidiennes qui donnent naissance aux différents styles de hip-hop japonais et aux familles de groupes de rap qui les incarnent. Dès lors, plutôt que de partir du principe que la culture populaire américaine a la même signification quel que soit l'endroit où elle fait son apparition, Condry affirme que nous devrions prêter attention à la manière dont les formes culturelles globales sont transposées dans la langue locale et les principaux lieux de performance, une perspective qu'il nomme « le globalisme genba ». Son approche constitue un moyen efficace de résoudre certains des problèmes posés par l'utilisation de l'ethnographie pour analyser un sujet aussi vaste que la globalisation de la culture populaire. mots-clés : mondialisation culturelle, hip-hop, Japon, terrain ethnographique
description: Japanese hip-hop and the globalization of popular culture In this essay, Ian Condry gives us an account of the globalization of American popular culture. On the surface, Japanese hip-hop music sems a perfect example of the way American popular culture is taking over the world. But a closer look reveals that there is a dynamic process by which the meaning of hip-hop is reinterpreted to fit into the Japanese context. In particular, Japanese artists and fans identify nightclubs as the genba, or “actual site” of local hip-hop. These noisy, crowded, smoky, late-night clubs offer insight into the everyday activities that give rise to different styles of Japanese hip-hop and the families of rap groups associated with them. So instead of assuming that American popular culture means the same thing wherever it appears, Condry argues we should attend to the ways global cultural forms are mediated through local language and key sites of performance, a perspective he calls “genba globalism”. This offers a productive way of resolving some of the challenges of using ethnography to study such a broad-ranging topic as the globalization of popular culture. keywords : cultural globalization, hip-hop, Japan, ethnographic fieldwork

These initial data should be useful for studying the dynamics of fully 3D, distorted black holes, such as those created by the spiraling coalescence of two black holes. We describe the mathematical construction of several families of such data sets, and show how to construct numerical solutions. We survey quantities associated with the numerically constructed solutions, such as ADM masses, apparent horizons, measurements of the horizon distortion, and the maximum possible radiation loss ($MRL$).

description: Fluid milk consumption has been on a decline in the United States for several years. The check off program funded by producers and processors of fluid milk provides generic advertising targeted at fluid milk consumption. Exploring how generic advertising affects fluid milk type consumption delineated by milk fat type is examined by incorporating a polynomial distributed lag advertising variable into an incomplete demand system. Seemingly unrelated regression results indicate that generic advertising indeed affects milk type consumption differently. The optimal advertising lag is five months. Whole milk has no significant advertising effects while low-fat and skim milks have positive, significant effects.

description: Triple points and nexus points are two interesting topological phases, which have been reported in some three-dimensional (3D) materials. Here, we propose that triple points, nexus points and related phases, such as topological tangle nodal lines, can be obtained by alternatively stacking two types of monolayers. Two conditions for the stacking monolayers are required: the first condition is that they have a three-fold (C3) rotation symmetry and three mirror planes along the C3 axis; the second condition is that one of the monolayers should be insulating while the other one should be metallic (or semiconducting) and has a double degenerate band and a nondegenerate band at Γpoint around the Fermi level. Hexagonal boron nitride (HBN) and α/α^'-boron sheets (α/α^'-BS) are suggested as candidate materials. Even if HBN is a wide-gap insulator, the interactions between layers lead to crossings of the nondegenerate and double degenerate bands along the direction normal to the nanosheets, and thus form triple/nexus points or related phases. A tight-binding model is adopted to explain the phase transition between triple points, nexus points and other related phases.

description: We develop the BPS preon conjecture to analyze the supersymmetric solutions of D=11 supergravity. By relating the notions of Killing spinors and BPS preons, we develop a moving G-frame method (G=GL(32,R), SL(32,R) or Sp(32,R)) to analyze their associated generalized holonomies. As a first application we derive here the equations determining the generalized holonomies of k/32 supersymmetric solutions and, in particular, those solving the necessary conditions for the existence of BPS preonic (31/32) solutions of the standard D=11 supergravity. We also show that there exist elementary preonic solutions, i.e. solutions preserving 31 out of 32 supersymmetries in a Chern--Simons type supergravity. We present as well a family of worldvolume actions describing the motion of pointlike and extended BPS preons in the background of a D'Auria-Fre type OSp(1|32)-related supergravity model. We discuss the possible implications for M-theory.

description: We study the appearance of directed energy current in homogeneous spatially extended systems coupled to a heat bath in the presence of an external ac field E(t). The systems are described by nonlinear field equations. By making use of a symmetry analysis we predict the right choice of E(t) and obtain directed energy transport for systems with a nonzero topological charge Q. We demonstrate that the symmetry properties of motion of topological solitons (kinks and antikinks) are equivalent to the ones for the energy current. Numerical simulations confirm the predictions of the symmetry analysis and, moreover, show that the directed energy current drastically increases as the dissipation parameter $α$ reduces. Our results generalize recent rigorous theories of currents generated by broken time-space symmetries to the case of interacting many-particle systems.

Can the notion of a homogeneous gravitational field be transferred from classical mechanics to the Relativistic Theory of Gravity ?

description: The generalization of the concept of homogeneous gravitational field from Classical Mechanics was considered in the framework of Einstein's General Relativity by Bogorodskii. In this paper, I look for such a generalization in the framework of the Relativistic Theory of Gravitation. There exist a substantial difference between the solutions in these two theories. Unfortunately, the solution obtained according to the Relativistic Theory of Gravitation can't be accepted because it doesn't fulfill the Causality Principle in this theory. So, it remains open in RTG the problem of finding a generalization of the classical concept of homogeneous gravitational field.

description: While federal rules require specific meat and poultry products to carry nutrition information labeling, these rules do not extend to fresh seafood products. This paper focuses on the extent to which the provision of nutrition information could impact consumer demand for seafood, with a special focus on parents with children, who influence the food preferences of future generations. Using a choice experiment, we found that providing nutrition information similar to the nutrition facts panel increased the marginal willingness to pay (MWTP) for all types of seafood studied; whereas information on the health benefit of Omega-3 fatty acids increased the MWTP for some types of seafood. This finding can inform the industry and policy-makers on the potential impact of introducing nutrition labels for raw seafood.

Turing patterns in a network-reduced FitzHugh-Nagumo model

description: Reduction of a two-component FitzHugh-Nagumo model to a single-component model with long-range connection is considered on general networks. The reduced model describes a single chemical species reacting on the nodes and diffusing across the links of a multigraph with weighted long-range connections that naturally emerge from the adiabatic elimination, which defines a new class of networked {dynamical} systems with local and nonlocal Laplace matrices. We study the conditions for the instability of homogeneous states in the original and reduced models and show that Turing patterns can emerge in both models.

description: In this review we describe a non-trivial relationship between perturbative gauge theory and gravity scattering amplitudes. At the semi-classical or tree level, the scattering amplitudes of gravity theories in flat space can be expressed as a sum of products of well defined pieces of gauge theory amplitudes. These relationships were first discovered by Kawai, Lewellen and Tye in the context of string theory, but hold more generally. In particular, they hold for standard Einstein gravity. A method based on D-dimensional unitarity can then be used to systematically construct all quantum loop corrections order-by-order in perturbation theory using as input the gravity tree amplitudes expressed in terms of gauge theory ones. More generally, the unitarity method provides a means for perturbatively quantizing massless gravity theories without the usual formal apparatus associated with the quantization of constrained systems. As one application, this method was used to demonstrate that maximally supersymmetric gravity is less divergent in the ultraviolet than previously thought.

description: Two-dimensional quantum gravity, defined either via scaling limits of random discrete surfaces or via Liouville quantum gravity, is known to possess a geometry that is genuinely fractal with a Hausdorff dimension equal to 4. Coupling gravity to a statistical system at criticality changes the fractal properties of the geometry in a way that depends on the central charge of the critical system. Establishing the dependence of the Hausdorff dimension on this central charge $c$ has been an important open problem in physics and mathematics in the past decades. All simulation data produced thus far has supported a formula put forward by Watabiki in the nineties. However, recent rigorous bounds on the Hausdorff dimension in Liouville quantum gravity show that Watabiki's formula cannot be correct when $c$ approaches $-\infty$. Based on simulations of discrete surfaces encoded by random planar maps and a numerical implementation of Liouville quantum gravity, we obtain new finite-size scaling estimates of the Hausdorff dimension that are in clear contradiction with Watabiki's formula for all simulated values of $c\in (-\infty,0)$. Instead, the most reliable data in the range $c\in [-12.5, 0)$ is in very good agreement with an alternative formula that was recently suggested by Ding and Gwynne. The estimates for $c\in(-\infty,-12.5)$ display a negative deviation from the latter formula, but the scaling is seen to be less accurate in this regime.
