description: High-quality free-standing InAs nanosheets are emerging layered semiconductor materials with potentials in designing planar Josephson junction devices for novel physics studies due to their unique properties including strong spin-orbit couplings, large Landé g-factors and the two dimensional nature. Here, we report an experimental study of proximity induced superconductivity in planar Josephson junction devices made from free-standing InAs nanosheets. The nanosheets are grown by molecular beam epitaxy and the Josephson junction devices are fabricated by directly contacting the nanosheets with superconductor Al electrodes. The fabricated devices are explored by low-temperature carrier transport measurements. The measurements show that the devices exhibit a gate-tunable supercurrent, multiple Andreev reflections, and a good quality superconductor-semiconductor interface. The superconducting characteristics of the Josephson junctions are investigated at different magnetic fields and temperatures, and are analyzed based on the Bardeen-Cooper-Schrieffer (BCS) theory. The measurements of ac Josephson effect are also conducted under microwave radiations with different radiation powers and frequencies, and integer Shapiro steps are observed. Our work demonstrates that InAs nanosheet based hybrid devices are desired systems for investigating forefront physics, such as the two-dimensional topological superconductivity.

description: We present a study of the equilibration process of nonequilibrium systems by means of molecular dynamics simulation technique. The nonequilibrium conditions are achieved in systems by defining velocity components of the constituent atoms randomly. The calculated Shannon en- tropy from the probability distribution of the kinetic energy among the atoms at different instants during the process of equilibration shows oscillation as the system relaxes towards equilibrium. Fourier transformations of these oscillating Shannon entropies reveal the existance of Debye frequency of the concerned system. From these studies it was concluded that the signature of the equilibration process of dynamical systems is the time invariance of Shannon entropy.

description: This Article studies the relationship between formal and informal con tract enforcement The theoretical literature treats the two strategies as separate phenomena. By contrast, a rich experimental literature considers whether the introduction of formal contracting and state enforcement "crowds out" the operation of informal contracting. Both literatures focus too narrowly on how formal contracts create incentives for parties to perform substantive actions, while assuming that informal enforcement depends on preexisting levels of trust. As a result, current scholarship misses the relationship between formal and informal contract mechanisms that characterizes contemporary contracting in practice. Parties respond to ?sing uncertainty by writing contracts that intertwine formal and informal mechanisms?what we call "braiding"?in a way that allows each to assess the disposition and capacity of the other to respond cooperatively and effectively to unforeseen circumstances. These parties agree on formal contracts for exchanging information about the progress and prospects of their joint activities, and it is this information sharing regime that "braids" the formal and informal elements of the contract and endogenizes trust. We argue that the low-powered enforcement associated with the formal governance structure in these braided contracts complements rather than crowds out the informal mechanisms that rely on increasing levels of trust. We examine the braiding phenomenon in a variety of contexts characterized by increasing uncertainty. In each instance, courts appear to have harnessed the braiding phenomenon by using low-powered sanctions to protect formal contractual "preliminaries." This technique allows potential collaborators to explore and develop their relations, but it does not impose mutually enforceable obligations to pursue a particular project. Despite the wisdom of temperate enforcement of braided contracts, however, courts that emphasize the contemporary duty to negotiate in good faith are often tempted to expand the legal sanction. We conclude by explaining how courts can best support the braiding strategies that are critical to the success of an integrated regime of formal and informal contracting.

description: We study the effect of an ultra-light primordial black hole (PBH) dominated phase on the gravitational wave (GW) spectrum generated by a cosmic string (CS) network formed as a result of a high-scale $U(1)$ symmetry breaking. A PBH-dominated phase leads to tilts in the spectrum via entropy dilution and generates a new GW spectrum from PBH density fluctuations, detectable at ongoing and planned near-future GW detectors. The combined spectrum has a unique shape with a plateau, a sharp tilted peak over the plateau, and a characteristic fall-off, which can be distinguished from the one generated in the combination of CS and any other matter domination or new exotic physics. We discuss how ongoing and planned future experiments can probe such a unique spectrum for different values of $U(1)$ breaking scale and PBH parameters such as initial mass and energy fraction.

description: We consider the decay of vortices trapped in the false vacuum of a theory of scalar electrodynamics in 2+1 dimensions. The potential is inspired by models with intermediate symmetry breaking to a metastable vacuum that completely breaks a U(1) symmetry, while in the true vacuum the symmetry is unbroken. The false vacuum is unstable through the formation of true vacuum bubbles; however, the rate of decay can be extremely long. On the other hand, the false vacuum can contain metastable vortex solutions. These vortices contain the true vacuum inside in addition to a unit of magnetic flux and the appropriate topologically nontrivial false vacuum outside. We numerically establish the existence of vortex solutions which are classically stable; however, they can decay via tunneling. In general terms, they tunnel to a configuration which is a large, thin-walled vortex configuration that is now classically unstable to the expansion of its radius. We compute an estimate for the tunneling amplitude in the semi-classical approximation. We believe our analysis would be relevant to superconducting thin films or superfluids.

description: The double ridge structure previously observed in Pb-Pb collisions has also been recently observed in high-multiplicity p-Pb collisions at sqrt(s_NN) = 5.02 TeV. These systems show a long-range structure (large separation in Delta_eta) at the near- (Delta_phi ~ 0) and away-side (Delta_phi ~ pi) of the trigger particle. In order to understand the nature of this effect the two-particle correlation analysis has been extended to identified particles. Particles are identified up to transverse momentum pT values of 4 GeV/c using the energy loss signal in the Time Projection Chamber detector, complemented with the information from the Time of Flight detector. This measurement casts a new light on the potential collective (i.e. hydrodynamic) behaviour of particle production in p-Pb collisions.

description: Strong magnets, such as neodymium-iron-boron magnets, are increasingly being manufactured as spheres. Because of their dipolar characters, these spheres can easily be arranged into long chains that exhibit mechanical properties reminiscent of elastic strings or rods. While simple formulations exist for the energy of a deformed elastic rod, it is not clear whether or not they are also appropriate for a chain of spherical magnets. In this paper, we use discrete-to-continuum asymptotic analysis to derive a continuum model for the energy of a deformed chain of magnets based on the magnetostatic interactions between individual spheres. We find that the mechanical properties of a chain of magnets differ significantly from those of an elastic rod: while both magnetic chains and elastic rods support bending by change of local curvature, nonlocal interaction terms also appear in the energy formulation for a magnetic chain. This continuum model for the energy of a chain of magnets is used to analyse small deformations of a circular ring of magnets and hence obtain theoretical predictions for the vibrational modes of a circular ring of magnets. Surprisingly, despite the contribution of nonlocal energy terms, we find that the vibrations of a circular ring of magnets are governed by the same equation that governs the vibrations of a circular elastic ring.
Verification and Validation Issues in Systems of Systems

description: The cutting edge in systems development today is in the area of "systems of systems" (SoS) large networks of inter-related systems that are developed and managed separately, but that also perform collective activities. Such large systems typically involve constituent systems operating with different life cycles, often with uncoordinated evolution. The result is an ever-changing SoS in which adaptation and evolution replace the older engineering paradigm of "development". This short paper presents key thoughts about verification and validation in this environment. Classic verification and validation methods rely on having (a) a basis of proof, in requirements and in operational scenarios, and (b) a known system configuration to be proven. However, with constant SoS evolution, management of both requirements and system configurations are problematic. Often, it is impossible to maintain a valid set of requirements for the SoS due to the ongoing changes in the constituent systems. Frequently, it is even difficult to maintain a vision of the SoS operational use as users find new ways to adapt the SoS. These features of the SoS result in significant challenges for system proof. In addition to discussing the issues, the paper also indicates some of the solutions that are currently used to prove the SoS.

description: Feature point (FP) detection is a fundamental step of many computer vision tasks. However, FP detectors are usually designed for low dynamic range (LDR) images. In scenes with extreme light conditions, LDR images present saturated pixels, which degrade FP detection. On the other hand, high dynamic range (HDR) images usually present no saturated pixels but FP detection algorithms do not take advantage of all the information present in such images. FP detection frequently relies on differential methods, which work well in LDR images. However, in HDR images, the differential operation response in bright areas overshadows the response in dark areas. As an alternative to standard FP detection methods, this study proposes an FP detector based on a coefficient of variation (CV) designed for HDR images. The CV operation adapts its response based on the standard deviation of pixels inside a window, working well in both dark and bright areas of HDR images. The proposed and standard detectors are evaluated by measuring their repeatability rate (RR) and uniformity. Our proposed detector shows better performance when compared to other standard state-of-the-art detectors. In uniformity metric, our proposed detector surpasses all the other algorithms. In other hand, when using the repeatability rate metric, the proposed detector is worse than Harris for HDR and SURF detectors.
title: How are human gait and energetics modified when walking over substrates of varying compliance?
Creators: name: Grant, Barbara
Publisher: name: University of Liverpool Repository
Year: 2023

description: Locomotion in the real-world requires humans to negotiate a variety of surfaces that have different material and mechanical properties and thus, require gait adjustments to maintain stability and efficiency. However, our current understanding of human gait and energetics is dominated by studies on hard, level surfaces in a laboratory environment. Previous research has shown that when walking on more irregular terrains such as loose rock surfaces, uneven surfaces and compliant substrates such as snow, grass and sand, there is an increase in energy expenditure. However, the primary mechanistic causes of this increase in energy costs is unclear. Previous studies suggest various biomechanical mechanisms including disruption to pendular energy recovery, increased muscle work, decreased muscle-tendon efficiency and increased gait variability. Yet, comparisons between studies is hindered by the measurement of different variables across studies and variation in substrates used. In this thesis, I focus on human walking over compliant substrates. This thesis aims to improve our understanding of the relationship between energetic costs, substrate properties, gait biomechanics and muscle activities. This is done by presenting a large experimental data set of human walking on both artificial (foam) and natural (sand) compliant substrates. The studies showed that compliant substrates had a considerable effect on gait biomechanics, muscle activation and energetics. On foam, there was greater energetic expenditure on more compliant substrates. On all compliant substrates, participants displayed greater ankle dorsiflexion during stance and greater knee and hip flexion during swing, increased muscle activation and changes to spatiotemporal parameters such as increased cycle time, stance time and swing time and decreased walking speed. The findings of this thesis suggests that overall gross adaptations like sagittal kinematics, spatiotemporal parameters and muscle activation are adopted in response to the depth of depression into a compliant substrate. However, there are specific gait changes due to substrate properties. Further research is required to explore gait adaptations on substrates with different material and mechanical properties. Furthermore, some of our results suggest there is large participant variability even in a relatively homogeneous study population. Therefore, future work should not only look at other demographic groups but also explore individual participant differences such as gender effects and variations in anatomical parameters.

description: This article presents a comparative analysis of Paolo Bozzi’s experimental phenomenology and of J.W. Goethe’s morphological method, which is considered one of the Italian scholar’s sources of inspiration. Starting from Bozzi’s education within the Gestalt psychology tradition, under the guidance of Gaetano Kanizsa, and taking into account also the recent interest shown for Bozzi by several exponents of the analytic tradition, this work draws attention to the basic features of the methodology adopted by the perceptologist in his work. In this regard, what proves to be fundamental is the role played by the various techniques of inter-observation by means of an active and practical approach to the material, rather than a purely contemplative one. Bozzi’s interest in Goethe’s naturalistic writings, from the morphological ones to the Farbenlehre (Theory of colours), makes it possible to highlight significant analogies and conceptual continuities with Goethe’s epistemology. First of all, a link between these two styles of research is provided by the subject “form,” or Gestalt, and its direct, accurate observation, as well as its presence in non-conventional contexts and its non-metaphysical character. Furthermore, it is evident that both authors employ a conception of experiment that is repeatable, conducted almost always in conditions that are open and not of the laboratory. Not less relevant is their scientific style, in which the distinction between the context of discovery and the context of justification plays no role. At the same time the extraordinary communication skills of both authors play a crucial role: their nonacademic way of writing accompanied by a sense of rigour and correctness makes the results outstanding and unique.

description: We study a non-Hermitian variant of the (2+1)-dimensional Dirac wave equation, which hosts a real energy spectrum with pairwise-orthogonal eigenstates. In the spatially uniform case, the Hamiltonian's non-Hermitian symmetries allow its eigenstates to be mapped to a pair of Hermitian Dirac subsystems. When a wave is transmitted across an interface between two spatially uniform domains with different model parameters, an anomalous form of Klein tunneling can occur, whereby reflection is suppressed while the transmitted flux is substantially higher or lower than the incident flux. The interface can even function as a simultaneous laser and coherent perfect absorber. Remarkably, the violation of flux conservation occurs entirely at the interface, as no wave amplification or damping takes place in the bulk. Moreover, at energies within the Dirac mass gaps, the interface can support exponentially localized boundary states with real energies. These features of the continuum model can also be reproduced in non-Hermitian lattice models.

description: We apply the recently developed extremely correlated Fermi liquid theory to the Anderson impurity model, in the extreme correlation limit. We develop an expansion in a parameter λ, related to n_d, the average occupation of the localized orbital, and find analytic expressions for the Green's functions to O(λ^2). These yield the impurity spectral function and also the self-energy Σ(ω) in terms of the two self energies of the ECFL formalism. The imaginary parts of the latter, have roughly symmetric low energy behaviour (~ ω^2), as predicted by Fermi Liquid theory. However, the inferred impurity self energy Σ"(ω) develops asymmetric corrections near n_d ~ 1, leading in turn to a strongly asymmetric impurity spectral function with a skew towards the occupied states. Within this approximation the Friedel sum rule is satisfied but we overestimate the quasiparticle weight z relative to the known exact results, resulting in an over broadening of the Kondo peak. Upon scaling the frequency by the quasiparticle weight z, the spectrum is found to be in reasonable agreement with numerical renormalization group results over a wide range of densities.

description: In holographic models of QCD, the running of the anomalous dimension of the quark bilinear operator leads to chiral symmetry breaking when gamma=1 and the Breitenlohner-Freedman bound is violated. In that case, the running drives the sigma meson mass tachyonic inducing the chiral symmetry breaking. Here we include the running anomalous dimension in the computation of the spectrum of bound states associated with other operators made of light quarks, such as the nucleon and exotic sexaquark states. We show that including the one loop gauge theory running can have substantial effects on the predictions. For example, the nucleon mass to rho mass ratio is improved and lies much closer to the observed value. A similar result is obtained for the Lambda and Xi baryons when strange quarks are included. A uuddss sexaquark state with a low enough mass to make it stable can be achieved, but this depends on the input assumptions about the running dimension.

description: Numerical relativity became a powerful tool to investigate the dynamics of binary problems with black holes or neutron stars as well as the very structure of General Relativity. Although public numerical relativity codes are available to evolve such systems, a proper understanding of the methods involved is quite important. Here we focus on the numerical solution of elliptic partial differential equations. Such equations arise when preparing initial data for numerical relativity, but also for monitoring the evolution of black holes. Because such elliptic equations play an important role in many branches of physics, we give an overview of the topic, and show how to numerically solve them with simple examples and sample codes written in C++ and Fortran90 for beginners in numerical relativity or other fields requiring numerical expertise.

Distress Associated with Clean-Eating: Understanding the Views of Healthcare Professionals

description: Eating disorders (EDs) have traditionally been perceived as illnesses that predominantly afflict young, White females. Recent times have shown an evolution in the complex and nuanced way that EDs can manifest, and there is growing appreciation that people of all ages, genders, and ethnicities can experience disordered eating. Research has been slow to adapt to this changing landscape, and certain populations and eating presentations remain understudied. This thesis addresses these knowledge gaps, particularly in relation to the male experience of EDs and the widely debated notion of harmful healthy eating.A comprehensive literature review was conducted to identify and synthesise published research on male barriers to help-seeking for EDs. Eight studies (with quantitative, qualitative, and mixed-methods designs) were shortlisted and analysed using a narrative synthesis approach. Results identified the presence of diverse barriers that operated across socioecological systems. Some bore similarity to those described in the female ED literature, however gender-specific barriers were also identified and understood as a response to unhelpful normative constructions of masculinity. Several ideas were discussed for clinical interventions to reduce barriers to professional care, and the importance of deconstructing stereotypic perceptions of masculinity and EDs was emphasised.In acknowledgement of the growing body of literature on ‘orthorexia nervosa’, the empirical project focused on understanding how distress associated with ‘clean’ and healthy eating presents in the UK. Twelve healthcare professionals from different disciplinary backgrounds were interviewed about their views and clinical experiences of ‘clean-eating distress’. Data were thematically analysed, generating four higher-order themes pertaining to the conceptualisation of clean-eating distress, factors associated with its development and maintenance, and recommendations for clinical intervention. Results highlighted a general recognition of the problematic nature of this eating presentation, however mixed opinions and contention existed about its conceptualisation and how it should be addressed by healthcare services.

description: Bosons in periodic potentials with very strong local interactions, known as the constrained bosons often exhibit interesting physical behavior. We investigate the ground state properties of a two-leg Bose-Hubbard ladder by imposing three-body constraint in one leg and hardcore constraint in the other. By using the cluster-mean-field theory approximation and the density matrix renormalization group method, we show that at unit filling, for strong two-body attraction among the three-body constrained bosons, the system becomes a gapped pair-Mott insulator where all the bosons form strong bound pairs and occupy the leg with three-body constraint. With increase in hopping strength this pair-Mott insulator phase undergoes a phase transition to the gapless superfluid phase for equal leg and rung hopping strengths. However, when the rung hopping is stronger compared to the leg hopping, we obtain a crossover to another gapped phase which is called the rung-Mott insulator phase where the bosons prefer to delocalize on the rungs than the legs. By moving away from unit filling, the system remains in the superfluid phase except for a small region below the gapped phase where a pair superfluid phase is stabilized in the regime of strong attractive interaction. We further extend our studies by considering three-body constraint on both the legs and find that the crossover from the gapped to gapped phase does not occur rather the system undergoes a transition from a pair-rung-Mott insulator phase to the superfluid phase at unit filling. Moreover, in this case we find the signature of the pair superfluid phase on either sides of this gapped phase.

description: Numerical studies of shock waves in large scale systems via kinetic simulations with millions of particles are too computationally demanding to be processed in serial. In this work we focus on optimizing the parallel performance of a kinetic Monte Carlo code for astrophysical simulations such as core-collapse supernovae. Our goal is to attain a flexible program that scales well with the architecture of modern supercomputers. This approach requires a hybrid model of programming that combines a message passing interface (MPI) with a multithreading model (OpenMP) in C++. We report on our approach to implement the hybrid design into the kinetic code and show first results which demonstrate a significant gain in performance when many processors are applied.

Based on our modeling of theoretical stream of the parent comet, we predicted several related meteorite (on Mercury) or meteor (on Venus and Mars) showers. There occurred the filaments, in the stream, with the particles coming to each planet from a similar direction. We found that this is a consequence of the specific distribution of argument of perihelion (peaked close to the value of $180^{\circ}$) and longitude of ascending node of the stream, and that the particles collide with each planet in an arc of their orbits being close to perihelion.

description: Convex regularization techniques are now widespread tools for solving inverse problems in a variety of different frameworks. In some cases, the functions to be reconstructed are naturally viewed as realizations from random processes; an important question is thus whether such regularization techniques preserve the properties of the underlying probability measures. We focus here on a case which has produced a very lively debate in the cosmological literature, namely Gaussian and isotropic spherical random fields, and we prove that Gaussianity and isotropy are not conserved in general under convex regularization over a Fourier dictionary, such as the orthonormal system of spherical harmonics.
Radio Emission from the First Quasars at $z \sim$ 6-15

description: Nearly 300 quasars have now been found at $z >$ 6, including nine at $z >$ 7. They are thought to form from the collapse of supermassive primordial stars to 10$^4$ - 10$^5$ M$_{\odot}$ black holes at $z \sim$ 20 - 25, which then rapidly grow in the low-shear environments of rare, massive halos fed by strong accretion flows. Sensitive new radio telescopes such as the Next-Generation Very Large Array (ngVLA) and the Square Kilometer Array (SKA) could probe the evolution of these objects at much earlier times. Here, we estimate radio flux from the first quasars at $z \sim$ 6 - 15 at 0.5 - 12.5 GHz. We find that SKA and ngVLA could detect a quasar like ULAS J1120+0641, a 1.35 $\times$ 10$^9$ M$_{\odot}$ black hole at $z =$ 7.1, at much earlier stages of evolution, $z \sim$ 14 - 15, with 100 hr integration times in targeted searches. The advent of these new observatories, together with the James Webb Space Telescope (JWST), Euclid, and the Roman Space Telescope (RST), will inaugurate the era of $z \lesssim$ 15 quasar astronomy in the coming decade.

description: Background Behaviour change is key to addressing both the challenges facing human health and wellbeing and to promoting the uptake of research findings in health policy and practice. We need to make better use of the vast amount of accumulating evidence from behaviour change intervention (BCI) evaluations and promote the uptake of that evidence into a wide range of contexts. The scale and complexity of the task of synthesising and interpreting this evidence, and increasing evidence timeliness and accessibility, will require increased computer support. The Human Behaviour-Change Project (HBCP) will use Artificial Intelligence and Machine Learning to (i) develop and evaluate a ‘Knowledge System’ that automatically extracts, synthesises and interprets findings from BCI evaluation reports to generate new insights about behaviour change and improve prediction of intervention effectiveness and (ii) allow users, such as practitioners, policy makers and researchers, to easily and efficiently query the system to get answers to variants of the question ‘What works, compared with what, how well, with what exposure, with what behaviours (for how long), for whom, in what settings and why?’. Methods The HBCP will: a) develop an ontology of BCI evaluations and their reports linking effect sizes for given target behaviours with intervention content and delivery and mechanisms of action, as moderated by exposure, populations and settings; b) develop and train an automated feature extraction system to annotate BCI evaluation reports using this ontology; c) develop and train machine learning and reasoning algorithms to use the annotated BCI evaluation reports to predict effect sizes for particular combinations of behaviours, interventions, populations and settings; d) build user and machine interfaces for interrogating and updating the knowledge base; and e) evaluate all the above in terms of performance and utility. Discussion The HBCP aims to revolutionise our ability to synthesise, interpret and deliver evidence on behaviour change interventions that is up-to-date and tailored to user need and context. This will enhance the usefulness, and support the implementation of, that evidence.

description: The centrality dependencies of the inclusive neutral pion and prompt photon nuclear modification factors for p+Pb collisions at the LHC are studied using a spatially dependent set of nuclear PDFs, EPS09s. The calculations are performed at mid- and forward rapidities searching for an observable which would optimally probe the spatial dependence of the nuclear PDFs. In addition, we discuss to which $x$ values of the nucleus the different observables are sensitive.

Bootstrapping Witten diagrams via differential representation in Mellin space

description: We explore the use of the differential representation of AdS amplitudes to compute Witten diagrams. The differential representation expresses AdS amplitudes in terms of conformal generators acting on contact Witten diagrams, which allows us to construct differential equations for Witten diagrams. These differential equations can then be transformed into difference equations in Mellin space, which can be solved recursively. Using this method, we efficiently re-computed scalar four-point amplitudes and obtained new results for scalar six-point amplitudes mediated by gluons and scalars, as well as two examples of scalar eight-point amplitudes from gluon exchange.

subject: FOS: Physical sciences

description: In this paper we study Gödel universe in the framework of $f(R,T)$ modified theories of gravity, where $R$ is the curvature scalar and $T$ the trace of the energy momentum tensor. We demonstrate that Gödel solution occurs in this modified theory and still we suggest a path to understanding the smallness of the cosmological constant.
