description: Explicit simulations of fluid mixtures of highly size-dispersed particles are constrained by numerical challenges associated with identifying pair-interaction neighbors. Recent algorithmic developments have ameliorated these difficulties to an extent, permitting more efficient simulations of systems with many large and small particles of disperse sizes. We leverage these capabilities to perform molecular dynamics simulations of binary sphere mixtures with elastically stiff particles approaching the hard sphere limit and particle size ratios of up to 50, approaching the colloidal limit. The systems considered consist of 500 large particles and up to nearly 3.6 million small particles with total particle volume fractions up to 0.51. Our simulations confirm qualitative predictions for correlations between large particles previously obtained analytically and for simulations employing effective depletion interactions, but also reveal additional insights into the near-contact structure that result from the explicit treatment of the small particle solvent. No spontaneous crystal nucleation was observed during the simulations, suggesting that nucleation rates in the fluid-solid coexistence region are too small to observe crystal nucleation for feasible simulation system sizes and timescales.

Turning performance
Muscle coordination
Balance control

description: Turning is an important activity of daily living and often compromised post-stroke. The fall rate for post-stroke individuals while turning is nearly four times as high compared to healthy adults, with most falls resulting in injury. Thus, there is a need for evidence-based rehabilitation targets to improve turning performance for post-stroke individuals. To produce well-coordinated movements, muscles can be organized into muscle modules (i.e., groups of co-excited muscles). Post-stroke these modules can be merged, leading to impaired muscle coordination and walking performance. However, the relationship between impaired coordination and turning performance is not well understood. Thus, the purpose of this study was to analyze the influence of impaired muscle coordination (i.e., merged modules) on turning performance (i.e., time to complete a turn, number of steps required to complete a turn, smoothness of performing the turn and balance control during a turn). Post-stroke individuals and healthy controls performed three tasks including overground straight line walking, a 90-degree turn and a 180-degree turn. The number of muscle modules during straight line walking were determined using non-negative matrix factorization. As few as two modules were found in post-stroke individuals. Differences in turning performance were only seen in the 180-degree turning performance measures. Those with two modules took longer to turn, used more steps and had less smooth movement. These results suggest obtaining independent modules should be an important aim in locomotor therapies aimed at improving turning performance. In addition, the time it takes to complete a 180-degree turn may be a useful clinical assessment measure of the degree of muscle coordination impairment post-stroke.

description: A game is played by a team of two --- say Alice and Bob --- in which the value of a random variable $x$ is revealed to Alice only, who cannot freely communicate with Bob. Instead, she is given a quantum $n$-level system, respectively a classical $n$-state system, which she can put in possession of Bob in any state she wishes. We evaluate how successfully they managed to store and recover the value of $x$ in the used system by requiring Bob to specify a value $z$ and giving a reward of value $ f(x,z)$ to the team. We show that whatever the probability distribution of $x$ and the reward function $f$ are, when using a quantum $n$-level system, the maximum expected reward obtainable with the best possible team strategy is equal to that obtainable with the use of a classical $n$-state system. The proof relies on mixed discriminants of positive matrices and --- perhaps surprisingly --- an application of the Supply--Demand Theorem for bipartite graphs. As a corollary, we get an infinite set of new, dimension dependent inequalities regarding positive operator valued measures and density operators on complex $n$-space. As a further corollary, we see that the greatest value, with respect to a given distribution of $x$, of the mutual information $I(x;z)$ that is obtainable using an $n$-level quantum system equals the analogous maximum for a classical $n$-state system.

description: We explored how often journal articles reporting HIV research sponsored by a developed country, but conducted in a developing country, mention research ethics committee (REC) approval from both countries, and what factors are involved. Of all such 2007 articles on Medline conducted in one of four developing countries (N = 154), only 52% mentioned such dual approval. Mention of dual vs. single approval was more likely among articles with ≥ 50% sponsor country authors, and the United States as the sponsor country. Also, dual approval was more likely among articles that mentioned informed consent and funding, had ≥ 50% sponsor country authors, were biomedical (vs. psychosocial), and appeared in journals adopting International Committee Medical Journal Editors (ICMJE) guidelines. Dual approval was thus obtained in only half of the articles and was associated with ethical and logistic issues, indicating the need for clearer and more universally accepted guidelines.

description: Interactions between atoms and lasers provide the potential for unprecedented control of quantum states. Fulfilling this potential requires detailed knowledge of frequency noise in optical oscillators with state-of-the-art stability. We demonstrate a technique that precisely measures the noise spectrum of an ultrastable laser using optical lattice-trapped $^{87}$Sr atoms as a quantum projection noise-limited reference. We determine the laser noise spectrum from near DC to 100 Hz via the measured fluctuations in atomic excitation, guided by a simple and robust theory model. The noise spectrum yields a 26(4) mHz linewidth at a central frequency of 429 THz, corresponding to an optical quality factor of $1.6\times10^{16}$. This approach improves upon optical heterodyne beats between two similar laser systems by providing information unique to a single laser, and complements the traditionally used Allan deviation which evaluates laser performance at relatively long time scales. We use this technique to verify the reduction of resonant noise in our ultrastable laser via feedback from an optical heterodyne beat. Finally, we show that knowledge of our laser's spectrum allows us to accurately predict the laser-limited stability for optical atomic clocks.

description: We investigate the effect of dipolar interactions in one-dimensional systems in connection with the possibility of observing exotic many-body effects with trapped atomic and molecular dipolar gases. By combining analytical and numerical methods, we show how the competition between short- and long-range interactions gives rise to frustrating effects which lead to the stabilization of spontaneously dimerized phases characterized by a bond-ordering. This genuine quantum order is sharply distinguished from Mott and spin-density wave phases, and can be unambiguously probed by measuring non local order parameters in-situ imaging techniques.

description: In this paper, we report an interesting kinematic phenomenon around the halos' edge related to the splashback radius. After the shell-crossing, cosmic flow exhibits various rotational morphologies via stream-mixing. Vorticity is generated in a particular way that coincides with the large-scale structure. Notably, one specific flow morphology, which is spiraling inward and compressing in the third direction, concentrates around halos. A detailed examination that reveals a sharp change in the logarithmic derivative of its volume fraction, coincides with the location of the splashback radius defined as the outermost caustic structure. Such a feature encodes valuable phase space information and provides a new perspective on understanding the dynamical evolution of halos. As a volume-weighted quantity, the profile of flow morphology is purely kinematic. And unlike other related studies, the rotational flow morphologies capture the anisotropic phase structure in the multi-stream region.

Experiments are composed as Python code, which is used to produce low-level hardware instructions. They are queued up and executed on the hardware in real time, synchronized by a pseudoclock. Experiment parameters are manipulated graphically, and analysis routines are run as new data is acquired.

description: This open access book gives a concise introduction to the practical implementation of monetary policy by modern central banks. It describes the conventional instruments used in advanced economies and the unconventional instruments that have been widely adopted since the financial crisis of 2007–2008. Illuminating the role of central banks in ensuring financial stability and as last resort lenders, it also offers an overview of the international monetary framework. A flow-of-funds framework is used throughout to capture this essential dimension in a consistent and unifying manner, providing a unique and accessible resource on central banking and monetary policy, and its integration with financial stability. Addressed to professionals as well as bachelors and masters students of economics, this book is suitable for a course on economic policy. Useful prerequisites include at least a general idea of the economic institutions of an economy, and knowledge of macroeconomics and monetary economics, but readers need not be familiar with any specific macroeconomic models.
Encounter-based model of a run-and-tumble particle

description: In this paper we extend the encounter-based model of diffusion-mediated surface absorption to the case of an unbiased run-and-tumble particle (RTP) confined to a finite interval $[0,L]$ and switching between two constant velocity states $\pm v$ at a rate $α$. The encounter-based formalism is motivated by the observation that various surface-based reactions are better modeled in terms of a reactivity that is a function of the amount of time that a particle spends in a neighborhood of an absorbing surface, which is specified by a functional known as the boundary local time. The effects of surface reactions are taken into account by identifying the first passage time (FPT) for absorption with the event that the local time crosses some random threshold $\widehat{\ell}$. In the case of a Brownian particle, the local time $\ell(t)$ is a continuous non-decreasing function of the time $t$. Taking $Ψ(\ell)\equiv ¶[\widehat{\ell}>\ell]$ to be an exponential distribution, $Ψ[\ell]=\e^{-κ_0\ell}$, is equivalent to imposing a Robin boundary condition with a constant rate of absorption $κ_0$. One major difference in the encounter-based model of an RTP is that the boundary local time $\ell(t)$ is a now a discrete random variable that counts the number of collisions of the RTP with the boundary. Given this modification, we show that in the case of a geometric distribution $Ψ(\ell)=z^{\ell}$, $z=1/(1+κ_0/v)$, we recover the RTP analog of the Robin boundary condition. This allows us to solve the boundary value problem (BVP) for the joint probability density for particle position and the local time, and thus incorporate more general models of absorption based on non-geometric distributions $Ψ(\ell)$.

description: Increasingly, physicians and patients face dilemmas of whether to exclude genetic information from medical charts, posing critical challenges for practice, research, policy, and education. Physicians and patients are obtaining more genetic information, yet medical records are rapidly becoming electronic, threatening confidentiality. Tensions thus arise between potential medical benefits vs social risks of including information. Use of genetic testing is rapidly increasing through clinicians and direct-to-consumer marketing. Direct-to-consumer tests may be definitive or show only slightly increased disease probabilities, but with advances may have increasing clinical utility. Several institutions have also discussed including whole genome data in medical records. Genetic discrimination has occurred with α1-antitrypsin deficiency, Huntington disease, and other mutations, although the extent remains unclear, partly because such discrimination can be subtle or difficult to prove. Patients may be passed over for promotion or marginalized, but not fired.
Guaiacol hydrogenation with in-situ generated hydrogen through aqueous phase glycerol reforming
Creators: name: Chen, Ziyin
Publisher: name: Imperial College London
Year: 2020

description: With increasing concern of environmental pollution and carbon emissions, energy production with renewable feedstocks especially biomass was become more attractive in recent decades. Liquid fuel, which was also called bio-oil, can be directly produced from biomass through fast pyrolysis. Nevertheless, the quality of the bio-oil generated from fast pyrolysis is low due to high oxygen and water content, low heating value and high viscosity. Therefore, upgrading of bio-oil is essential for its full utilization as a kind of renewable energy. This work is aimed to study an innovative method for the bio-oil upgrading without external hydrogen that hydrogenating a bio-oil model compound with in-situ hydrogen generated from aqueous phase reforming of glycerol. The process was studied using guaiacol as the model compound of bio-oil and conducted in a batch stirred reactor. Initially, experiments of hydrogen production from glycerol reforming were performed at different operation conditions to maximize hydrogen yield. Then experiments were conducted to study hydrogenation of guaiacol with in-situ produced hydrogen from glycerol. The effect of the primary process variables was studied, and a potential reaction pathway was proposed followed by a catalysts screening in this process as a collaboration with Boreskov Institute of Catalysis (Novosibirsk, Russia). For the experiments of glycerol reforming, it was found that the operating conditions had great influence on the hydrogen yield and selectivity of gas product. Optimum conditions were determined where the maximum hydrogen yield was obtained. In the experiments of hydrogenation of guaiacol, it was notable that hydrogenated aromatic compounds were formed in the absence of glycerol. It is believed that methanol produced from hydrolysis of guaiacol is the internal source of hydrogen. In addition, it was observed that guaiacol conversion and yield of organic soluble product increased with additional glycerol. Moreover, Ni/Al2O3 showed a better performance than promoted Ni based catalysts in terms of guaiacol conversion and organic soluble product yield. It is predicted that the capacity of hydrogen production of Ni based catalysts was inhibited by promotors.

Continuous ultrahigh molecular weight polyethylene fibre as through-thickness reinforcement for sandwich-structured composites
Creators: name: Li, Diyang
Publisher: name: Imperial College London
Year: 2020

description: This thesis describes the design and fabrication of continuous ultra-high molecular weight polyethylene (UHMWPE) fibre as through-thickness reinforcement for sandwich-structured composites consisting of mechanically frothed epoxy foam as the foam core material. It was found that the introduction of continuous UHMWPE fibres into an epoxy foam core increased its core shear, flatwise compressive, as well as edgewise tensile properties. More importantly, the failure of the continuous UHMWPE fibre-reinforced epoxy foam in tension was delayed. This thesis also discusses the properties of sandwich-structured composites with UHMWPE fibres weaved through both the facesheets and the epoxy foam core. It was found that sandwich-structured composites consisting of continuous UHMWPE fibres performed significantly better than their discontinuous fibre-reinforced counterparts in both core shear and flatwise tension. Charpy impact test further showed that continuous UHMWPE fibre-reinforced sandwich-structured composites improved the impact toughness of the resulting sandwich-structured composites. A set of strain energy based analytical equations was derived to estimate the upper bound mechanical properties of these reinforced epoxy foams and sandwich-structured composites and compared with experimentally measured values.

description: In this paper we apply the gravitational decoupling method for dynamical systems in order to obtain a new type of solution which can describe a hairy dynamical black hole. We consider three cases of decoupling. The first one is the simplest and well-known when the mass function is the function only of space coordinate $r$. The second case is Vaidya spacetime case when the mass function depends on time $v$ . And the third case represents the generalization of these two cases: the mass function is the function of both $r$ and $v$. We also calculate the apparent horizon and singularity location for all three cases.

description: Let f be an entire function that has only finitely many critical and asymptotic values. Up to topological equivalence, the function $f$ is determined by combinatorial information, more precisely by an infinite graph known as a "line-complex". In this note, we discuss the natural question whether the order of growth of an entire function is determined by this combinatorial information. The search for conditions that imply a positive answer to this question leads us to the "area property", which turns out to be related to many interesting and important questions in conformal dynamics and function theory. These include a conjecture of Eremenko and Lyubich, the measurable dynamics of entire functions, and pushforwards of quadratic differentials. We also discuss evidence that invariance of order and the area property fail in general.

Study design: We examined 207 websites, of which 128 were egg provider agency 40%) or clinic (60%) websites that recruited providers online. We compared them regarding several variables related to adherence to American Society for Reproductive Medicine (ASRM) guidelines. Results: According to their respective websites, agencies were more likely than clinics to mention ASRM guidelines, be located in the West/Pacific, indicate compensation, offer a fee range, set their minimum > $5,000, specify preferable traits, cap provider age at 31, require an education minimum, allow both parties to meet, discuss short-term risks, and not acknowledge a possible cancer risk. Only 25.5% of agencies and 19.5% of clinics mention psychological/emotional risks, and 11.8% and 5.2%, respectively, mention risk to future fertility. Conclusion: This research, the first to systematically compare several key aspects of egg provider agencies versus clinics, suggests it significant differences in adherence to guidelines, raising several concerns and suggesting needs for consideration of improved monitoring and regulation by ASRM or others.

description: The existence of exotic spin-dependent forces may shine light on new physics beyond the Standard Model. We utilize two iron shielded SmCo$_5$ electron-spin sources and two optically pumped magnetometers to search for exotic long-range spin-spin-velocity-dependent force. The orientations of spin sources and magnetometers are optimized such that the exotic force is enhanced and common-mode noise is effectively subtracted. We set direct limit on proton-electron interaction in the force range from 1\,cm to 1\,km. Our experiment represents more than ten orders of magnitude improvement than previous works.

description: We study charged and radially excited boson stars in both asymptotically flat as well as asymptotically Anti-de Sitter space-time. We demonstrate that two different types of radially excited solutions exist~: one that persists in the linear limit of small scalar fields, in which analytical arguments suggest the existence of these solutions, and one that appears only in the highly non-linear regime of the model. We also demonstrate that the formation of wavy scalar hair discussed previously for black holes and boson stars in asymptotically flat space-time persists for asymptotically Anti-de Sitter space-time.

description: In this paper, we prove the well-posedness of a conditional McKean Lagrangian stochastic model endowing the specular boundary condition and the mean no--permeability condition in smooth bounded confinement domain D. This result extend our previous work, where we dealt with the case where the confinement domain is the upper--half plane and where the specular boundary condition is introduced in generic Langevin process owing to some well known results on the law of the passage times at zero of the Brownian primitive. The extension to more general confinement domain exhibit more difficulties that can be handled by combining stochastic calculus and the analysis of kinetic equations. As a prerequisite for the nonlinear case, we construct a Langevin process confined in D and satisfying the specular boundary condition. We then use PDE techniques to construct the time-marginal densities of the nonlinear process from which we are able to exhibit the conditional McKean Lagrangian stochastic model.

description: In the gravitational collapse of matter beyond spherical symmetry, gravitational waves are necessarily present. On the other hand, gravitational waves can collapse to a black hole even without matter. One might therefore wonder how the interaction and competition between the matter fields and gravitational waves affects critical phenomena at the threshold of black hole formation. As a toy model for this, we study the threshold of black-hole formation in 4+1 dimensions, where we add a massless minimally coupled scalar matter field to the gravitational wave ansatz of Bizón, Chmaj and Schmidt (in a nutshell, Bianchi~IX on $S^3\times\text{radius}\times\text{time}$). In order to find a stable discretisation of the equation governing the gravitational waves in 4+1 physical dimensions, which has the same principal part as the spherical wave equation in 9+1 dimensions, we first revisit the problem of critical spherical scalar field collapse in $n+2$ dimensions with large $n$. Returning to the main problem, we find numerically that weak gravitational wave perturbations of the scalar field critical solution decay, while weak scalar perturbations of the gravitational wave critical solution also decay. A dynamical systems picture then suggests the existence of a codimension-two attractor. We find numerical evidence for this attractor by evolving mixed initial data and fine-tuning both an overall amplitude and the relative strength of the two fields.

description: We use our cluster population model, cBHBd, to explore the mass distribution of merging black hole binaries formed dynamically in globular clusters. We include in our models the effect of mass growth through hierarchical mergers and compare the resulting distributions to those inferred from the third gravitational wave transient catalogue. We find that none of our models can reproduce the peak at $m_1\simeq 10M_\odot$ in the primary black hole mass distribution that is inferred from the data. This disfavours a scenario where most of the sources are formed in globular clusters. On the other hand, a globular cluster origin can account for the inferred secondary peak at $m_1\simeq 35M_\odot$, which requires that the most massive clusters form with half-mass densities $ρ_{\rm h,0} \gtrsim 10^4 M_\odot \rm pc^{-3}$. Finally, we find that the lack of a high mass cut--off in the inferred mass distribution can be also explained by the repopulation of an initial mass gap through hierarchical mergers. Matching the inferred merger rate above $\simeq 50M_\odot$ requires both initial cluster densities $ρ_{\rm h,0} \gtrsim 10^4 M_\odot \rm pc^{-3}$, and that black holes form with nearly zero spin. A hierarchical merger scenario makes specific predictions for the appearance and position of multiple peaks in the black hole mass distribution, which can be tested against future data.

description: Objectives: Disclosures of funding sources and conflicts of interests (COI) in published peer-reviewed journal articles have recently begun to receive some attention, but many critical questions remain, for example, how often such reporting occurs concerning research conducted in the developing world and what factors may be involved. Design: Of all articles indexed in Medline reporting on human subject HIV research in 2007 conducted in four countries (India, Thailand, Nigeria and Uganda), this study explored how many disclosed a funding source and COI, and what factors are involved. Results: Of 221 articles that met the criteria, 67.9% (150) disclosed the presence or absence of a funding source, but only 20% (44) disclosed COI. Studies from Uganda were more likely, and those from Nigeria were less likely to mention a funding source (p<0.001). Of articles in journals that had adopted International Committee of Medical Journal Editors (ICMJE) guidelines, 56% did not disclose COI. Disclosure of funding was more likely when: ≥50% of the authors and the corresponding author were from the sponsoring country, the sponsor country was the USA, and the articles were published in journals in which more of the editors were from the sponsoring countries. Conclusions: Of the published studies examined, over a third did not disclose funding source (ie, whether or not there was a funding source) and 80% did not disclose whether COI existed. Most articles in ICMJE-affiliated journals did not disclose COI. These data suggest the need to consider alteration of policies to require that published articles include funding and COI information, to allow readers to assess articles as fully as possible.

description: A new muon source has been proposed to conduct muon spin rotation/relaxation/resonance ($μ$SR) measurements at China Spallation Neutron Source (CSNS). Only 1 Hz of the CSNS proton beams (25 Hz in total) will be allocated for muon production. To make better use of muons in every pulse, an ultrahigh-array $μ$SR spectrometer (UHAM) with thousands of detector channels is under design. Due to such a high granularity of detectors, multiple counting events generated from particle scattering or spiral motions of positrons in a strong longitudinal field should be carefully considered in the design. Six different structures were modeled and simulated based on two types of angular orientations (parallel arrangement and pointing arrangement) and three kinds of spectrometer geometries (cylinder, cone and sphere). A quality factor, $Q$, was proposed to evaluate the performance of these structures by integrating their impacts on the overall asymmetry, the counting rate and the percentage of multiple counts. According to the simulation, the conical structure with detectors pointing to the sample has the highest $Q$ in both zero field and longitudinal field. The results also show that all kinds of structures cannot be operated under strong longitudinal fields with a strength over 2 T. The full simulation of a $μ$SR spectrometer can provide good guidance for the construction of the UHAM in the upcoming upgrade of CSNS.

description: Wireless systems must be resilient to jamming attacks. Existing mitigation methods based on multi-antenna processing require knowledge of the jammer's transmit characteristics that may be difficult to acquire, especially for smart jammers that evade mitigation by transmitting only at specific instants. We propose a novel method to mitigate smart jamming attacks on the massive multi-user multiple-input multiple-output (MU-MIMO) uplink which does not require the jammer to be active at any specific instant. By formulating an optimization problem that unifies jammer estimation and mitigation, channel estimation, and data detection, we exploit that a jammer cannot change its subspace within a coherence interval. Theoretical results for our problem formulation show that its solution is guaranteed to recover the users' data symbols under certain conditions. We develop two efficient iterative algorithms for approximately solving the proposed problem formulation: MAED, a parameter-free algorithm which uses forward-backward splitting with a box symbol prior, and SO-MAED, which replaces the prior of MAED with soft-output symbol estimates that exploit the discrete transmit constellation and which uses deep unfolding to optimize algorithm parameters. We use simulations to demonstrate that the proposed algorithms effectively mitigate a wide range of smart jammers without a priori knowledge about the attack type.

description: Early detection of nasopharyngeal carcinoma poses a challenging endeavor. The absence of diagnostic biomarkers that offer both high sensitivity and specificity represents a substantial contributing factor to the unfavorable prognosis of Nasopharyngeal Carcinoma (NPC) patients. We aimed to create a non-invasive diagnostic method for the identification of NPC through the application of circulating cell-free DNA (cfDNA).

description: One approach to the development of quantum search algorithms is the quantum walk. A spatial search can be effected by the continuous-time evolution of a single quantum particle on a graph containing a marked site. In many physical implementations, however, one might expect to have multiple particles. In interacting bosonic systems at zero temperature, the dynamics is well-described by a discrete nonlinear Schrodinger equation. We investigate the role of nonlinearity in determining the efficiency of the spatial search algorithm within the quantum walk model, for the complete graph. The analytical calculations reveal that the nonlinear search time scales with size of the search space N like the square root of N, equivalent to the linear case though with a different overall constant. The results indicate that interacting Bose-Einstein condensates at zero temperature could be natural systems for the implementation of the quantum search algorithm.
