description: Context. Recently, SDSS J143016.05+230344.4 (J1430+2303) was reported to be a supermassive black hole binary (SMBHB) in the final coalescence phase. It is probably the first SMBHB coalescence event observable in human history. Radio observations of J1430+2303 before and after coalescence will provide a unique diagnosis of the energetics and environment of the SMBHB. Aims. We explore the radio emission from the galactic nucleus region that is closely related to the current X-ray and optical activities and helps to understand the state of black hole accretion and outflow before coalescence. Methods. Very long baseline interferometry (VLBI) imaging is the only method that offers milli-arcsecond-level high resolution that can exclude the contamination by diffuse emission on galactic scales. We observed J1430+2303 with the European VLBI Network at 1.7 GHz and with the Very Long Baseline Array at 1.6 and 4.9 GHz in late February and early March 2022. Results. A compact component is detected in all three VLBI images. It has a brightness temperature of > 10^8 K, an unresolved morphology with a size < 0.8 pc, and a flat radio spectrum. These observational features are inconsistent with large opening-angle outflows or winds, but indicate that this compact component might be a jet or a corona. Nearly 60% of the emission is resolved by VLBI and may come from remnant lobes of previous radio activities, the outer layers of a structured jet, or shocks formed by the disc winds in the narrow line region. Conclusions. Current VLBI images do not yet show signs of radio outbursts. Our observations provide pre-coalescence radio data that are an important reference for future comparative studies with the post-merger. In particular, further resolving the jet will pave the way for probing the dynamical features associated with inspiralling binary black holes.

description: No abstracts are to be cited without prior reference to the author.Evidence indicates that absorption of atmospheric carbon dioxide (CO2) in the ocean has already decreased pH levels by 0.1 pH units since 1750, and CO2 concentrations are projected to rise further by the end of the century as fossil fuel reserves continue to be exploited. To date, a large proportion of ocean acidification (OA) research undertaken has tended to concentrate on benthic or planktonic species which are of limited direct importance to fisheries and aquaculture. Furthermore, some of the available evidence is contradictory with some studies demonstrating that species are robust to lower pH whilst others show marked sensitivity. There is still much research needed to understand some of the observed organisms’ responses to changes in pH under laboratory and under their natural environment. In the UK, fisheries generate more than £800 million of revenue per year and support 30,000 jobs. Aquaculture generates £350 million and supports a further 4,200 jobs. It is important to document the effects of ocean acidification on species of commercial importance. This presentation concentrates mainly on experimental work conducted on lobsters, cockles and scallops, providing further understanding on the effects of ocean acidification in connection to co-stressors, such as temperature and/or food availability. This work considers the main changes in the growth, development and shell composition of different species. This work also provides the contextual environmental variability observed in some of these areas, which is necessary to place the results into wider context. The outcomes of this research are paramount to understand the future climate change scenarios, which could have important economic and environmental consequences in commercially important shellfish. This information is deemed important for policy makers, scientists and conservation colleagues working on ocean acidification research.
ADHESIVE PROPERTIES OF TOPOGRAPHICALLY PATTERNED AND MECHANICALLY DEFORMED SURFACES

description: Adhesives are becoming more widely used for applications that previously relied on mechanical methods to secure the interface of two materials due to their cost effectiveness, lower weight, and ease of use. Examples of these new adhesive spaces include functional adhesives for robotic or manufacturing applications, composite materials in automotives and aircrafts, and wearable medical devices. As adhesives continue to push into new spaces, new methods must be developed to control their adhesive properties. Furthermore, understanding how the adhesive properties of these materials change due to deformation is critical in order to select or design new adhesives for specific applications. In this work we develop a material with pressure tunable adhesion by utilizing surface patterning. A simple and scalable fabrication method, polymer thin film dewetting, is used to pattern the surface of a soft elastomer with stiff, microscopic, and axisymmetric asperities. Patterning of the surface with these asperities leads to pressure tunable adhesion where adhesion strength increases with increasing applied pressure. Additionally, it is shown that changes to the relationship between adhesion strength and applied pressure by altering the pattern geometry are investigated. The surface properties of amorphous elastomers have long been assumed to be independent of deformation. However, experimental studies within the last 15 years have shown this to be false for very soft solids and gels with moduli on the order of 10s-100s KPa when deformation of the material is below a critical length scale. The surface stress of these materials differs from the bulk and are dependent on the degree of deformation of the solid. Theoretical works have also shown this to be true for stiffer materials, however it is difficult to use the same experimental techniques to probe the surface stress of elastomers with moduli on the order of MPa. In this work, a new experimental technique is proposed to investigate the deformation dependent surface properties of elastomers. Additionally, this same technique allows us to probe the deformation-dependent adhesion properties of elastomers. We show that the shape of contact between a uniaxially stretched elastomer and rigid spherical probe provides insight into changes in surface stress. Furthermore, our results indicate that material composition, specifically filler composition and loading, affects the adhesion hysteresis of these elastomers.

description: Human tendons adapt to mechanical loading, yet there is little information on the effect of the temporal coordination of loading and recovery or the dose–response relationship. For this reason, we assigned adult men to either a control or intervention group. In the intervention group, the two legs were randomly assigned to one of five high-intensity Achilles tendon (AT) loading protocols (i.e., 90% maximum voluntary contraction and approximately 4.5 to 6.5% tendon strain) that were systematically modified in terms of loading frequency (i.e., sessions per week) and overall loading volume (i.e., total time under loading). Before, at mid-term (8 weeks) and after completion of the 16 weeks intervention, AT mechanical properties were determined using a combination of inverse dynamics and ultrasonography. The cross-sectional area (CSA) and length of the free AT were measured using magnetic resonance imaging pre- and post-intervention. The data analysis with a linear mixed model showed significant increases in muscle strength, rest length-normalized AT stiffness, and CSA of the free AT in the intervention group (p < 0.05), yet with no marked differences between protocols. No systematic effects were found considering the temporal coordination of loading and overall loading volume. In all protocols, the major changes in normalized AT stiffness occurred within the first 8 weeks and were mostly due to material rather than morphological changes. Our findings suggest that—in the range of 2.5–5 sessions per week and 180–300 s total high strain loading—the temporal coordination of loading and recovery and overall loading volume is rather secondary for tendon adaptation.

description: The ATLAS detector is set to undergo a substantial upgrade termed the "Phase-II" upgrade during the Long-Shutdown in preparation for the start of operation of the High Luminosity Large Hadron Collider (HL-LHC). This paper describes the development and implementation of the Phase-II upgrade low voltage power supply transformer-coupled buck converter (Brick) test bench. A large scale production of approximately 2048 finger low voltage power supplies, with an identical output voltage, is set to be undertaken in the year 2022. This production will culminate in the complete replacement of the LVPS Brick V7.5.0 currently installed within the Tile Calorimeter. Due to the location of the Bricks within the inner barrel of the TileCal their reliability is of the utmost importance. Therefore, the implementation of performance screening will be implemented and will involve the testing and certification of all Bricks produced. A custom test bench has been developed in order to facilitate the above-mentioned testing. The test bench described herein quantifies and logs the performance of an upgrade Brick allowing for comparison with predefined performance metrics before being approved and subsequently installed on-detector.

description: Fast Radio Bursts (hereafter FRBs) can be used in cosmology by studying the Dispersion Measure (hereafter DM) as a function of redshift. The large scale structure of matter distribution is regarded as a major error budget for such application. Using optical galaxy and dispersion measure mocks built from N-body simulations, we have shown that the galaxy number density can be used as a tracer for large scale electron density and help improve the measurement of DM as a function of redshift. We have shown that, using the line-of-sight galaxy number counts within 1' around the given localized FRB source can help improve the cosmological parameter constraints by more than 20%.

description: Stanley considered suitably normalized characters of the symmetric groups on Young diagrams having a special geometric form, namely multirectangular Young diagrams. He proved that the character is a polynomial in the lengths of the sides of the rectangles forming the Young diagram and he conjectured an explicit form of this polynomial. This Stanley character polynomial and this way of parametrizing the set of Young diagrams turned out to be a powerful tool for several problems of the dual combinatorics of the characters of the symmetric groups and asymptotic representation theory, in particular to Kerov polynomials.

description: The study of chemical reactions in environments under nonequilibrium conditions has been of interest recently in a variety of contexts, including current-induced reactions in molecular junctions and scanning tunneling microscopy experiments. In this work, we outline a fully quantum mechanical, numerically exact approach to describe chemical reaction rates in such nonequilibrium situations. The approach is based on an extension of the flux correlation function formalism to nonequilibrium conditions and uses a mixed real and imaginary time hierarchical equations of motion approach for the calculation of rate constants. As a specific example, we investigate current-induced intramolecular proton transfer reactions in a molecular junction for different applied bias voltages and molecule-lead coupling strengths.

description: No abstracts are to be cited without prior reference to the author.Wild Atlantic salmon (Salmo salar) individuals can spend anywhere between one and five years feeding atsea before returning, often to their natal river, to spawn. Larger, late-maturing ‘multi-sea winter’ (MSW),individuals are highly sought after by anglers. This late-maturing life-history strategy is also importantfrom a biodiversity perspective, thus creating a management conflict. Knowledge of the genetic basis ofsea-age would provide a foundation for developing effective management strategies for conservation ofthis important life-history trait. We examined the genetic basis of sea-age in Atlantic salmon by analysing>200,000 genome-wide SNPs in 57 salmon populations from three phylogeographic lineages. We identifieda major-effect gene that explained almost 40% of the variation in sea-age across populations. Individualshomozygous for the high sea-age allele were predicted to mature, on average, 10 months later than lowsea-age allele homozygotes; a remarkable shift considering average population sea age is 1.6 years. Wealso found evidence for divergent selection that supports the hypothesis that large-effect genes may evolvewhen there is high gene flow among locally adapted populations. This finding may provide a means forrestoring 1SW and MSW components in wild populations where the MSW phenotype has been declining.

description: The chemical composition of the solar corona is different from that of the solar photosphere, with the strongest variation being observed in active regions (ARs). Using data from the Extreme Ultraviolet (EUV) Imaging Spectrometer (EIS) on Hinode, we present a survey of coronal elemental composition as expressed in the first ionisation potential (FIP) bias in 28 ARs of different ages and magnetic flux content, which are at different stages in their evolution. We find no correlation between the FIP bias of an AR and its total unsigned magnetic flux or age. However, there is a weak dependence of FIP bias on the evolutionary stage, decreasing from 1.9-2.2 in ARs with spots to 1.5-1.6 in ARs that are at more advanced stages of the decay phase. FIP bias shows an increasing trend with average magnetic flux density up to 200 G but this trend does not continue at higher values. The FIP bias distribution within ARs has a spread between 0.4 and 1. The largest spread is observed in very dispersed ARs. We attribute this to a range of physical processes taking place in these ARs including processes associated with filament channel formation. These findings indicate that, while some general trends can be observed, the processes influencing the composition of an AR are complex and specific to its evolution, magnetic configuration or environment. The spread of FIP bias values in ARs shows a broad match with that previously observed in situ in the slow solar wind.

description: Micromagnetic modelling provides the ability to simulate large magnetic systems accurately without the computational cost limitation imposed by atomistic modelling. Through micromagnetic modelling it is possible to simulate systems consisting of thousands of grains over a time range of nanoseconds to years, depending upon the solver used. Here we present the creation and release of an open-source multi-timescale micromagnetic code combining three key solvers: Landau-Lifshitz-Gilbert; Landau-Lifshitz-Bloch; Kinetic Monte Carlo. This code, called MARS (Models of Advanced Recording Systems), is capable of accurately simulating the magnetisation dynamics in large and structurally complex single- and multi-layered granular systems. The short timescale simulations are achieved for systems far from and close to the Curie point via the implemented Landau-Lifshitz-Gilbert and Landau-Lifshitz-Bloch solvers respectively. This enables read/write simulations for general perpendicular magnetic recording and also state of the art heat assisted magnetic recording (HAMR). The long timescale behaviour is simulated via the Kinetic Monte Carlo solver, enabling investigations into signal-to-noise ratio and data longevity. The combination of these solvers opens up the possibility of multi-timescale simulations within a single software package. For example the entire HAMR process from initial data writing and data read back to long term data storage is possible via a single simulation using MARS. The use of atomistic parameterisation for the material input of MARS enables highly accurate material descriptions which provide a bridge between atomistic simulation and real world experimentation. Thus MARS is capable of performing simulations for all aspects of recording media research and development. This ranges from material characterisation and optimisation to system design and implementation.

description: By using the Faddeev-Popov quantization procedure, we demonstrate that the radiative effects computed using the first-order and second-order Einstein-Hilbert action for General Relativity are the same, provided one can discard tadpoles. In addition, we show that the first order form of this action can be used to obtain a set of Feynman rules that involves just two propagating fields and three three-point vertices; using these rules is considerably simpler than employing the infinite number of vertices that occur in the second-order form. We demonstrate this by computing the one-loop, two-point function.

description: Some HII regions that surround young stellar clusters are bordered by molecular shells that appear to expand at a rate inconsistent with our current model simulations. In this study we focus on the dynamics of Sharpless 171 (including NGC 7822), which surrounds the cluster Berkeley 59. We aim to compare the velocity pattern over the molecular shell with the mean radial velocity of the cluster for estimates of the expansion velocities of different shell structures, and to match the observed properties with model simulations. Optical spectra of 27 stars located in Berkeley 59 were collected at the Nordic Optical Telescope, and a number of molecular structures scattered over the entire region were mapped in $^{13}$CO(1-0) at Onsala Space Observatory. We obtained radial velocities and MK classes for the cluster's stars. At least four of the O stars are found to be spectroscopic binaries, in addition to one triplet system. From these data we obtain the mean radial velocity of the cluster. From the $^{13}$CO spectra we identify three shell structures, expanding relative to the cluster at moderate velocity (4 km/s), high velocity (12 km/s), and in between. The high-velocity cloudlets extend over a larger radius and are less massive than the low-velocity cloudlets. We performed a model simulation to understand the evolution of this complex. Our simulation of the Sharpless 171 complex and Berkeley 59 cluster demonstrates that the individual components can be explained as a shell driven by stellar winds from the massive cluster members. However, our relatively simple model produces a single component. Modelling of the propagation of shell fragments through a uniform interstellar medium demonstrates that dense cloudlets detached from the shell are decelerated less efficiently than the shell itself. They can reach greater distances and retain higher velocities than the shell.

description: This paper studies invasion waves in the diffusive Competitor-Competitor-Mutualist model generalizing the 2-species Lotka-Volterra model studied by Weinberger et al. The mutualist may benefit the invading or the resident species producing two different types of invasions. Sufficient conditions for linear determinacy are derived in both cases, and when they hold, explicit formulas for linear spreading speeds of the invasions are obtained by linearizing the model. While in the first case the linear speed is increased by the mutualist, it is unaffected in the second case. Mathematical methods are based on converting the model into a cooperative reaction-diffusion system.

description: No abstracts are to be cited without prior reference to the author.Theragra chalcogramma, a walleye pollock has widespread geographical distributions and exploitsdifferent ecological niches from extremely low temperature to variable temperature oceans. Thepopulations from latitudinal gradient provide natural replication to study on the evolutionaryresponse towards the environmental gradients. A new method which targeting the SNP markers inISSR region across the genome were used to study the population structure and divergent loci inpollock from Bering Sea and Japans’ ocean. A total of 160 SNP loci were obtained from the adoptedmethod and population divergence and structuring were observed in both populations, confirmingthe existence of genetic break between populations (FST: 0.05–0.07). The evidence of outlier SNPsenhanced the dramatic divergence between Bering Sea and Japan oceans’ populations (FST: 0.183-0.625). A correlation study of allele frequencies at each SNP locus with environmental parametersshowed the occurrence of two outliers SNPs, which might respond to an ocean temperature andsalinity gradients in the populations. Further investigation of outliers SNP by BLAST were positionedthe loci near to a gene which play a vital role in transcription of major histocompatibility (MHC) gene,an evolutionary conserved gene in adaptive immune system in vertebrates which might explained theselection on the gene.

description: Flux densities are basic observation parameters to describe pulsars. In the most updated pulsar catalog, 24% of the listed radio pulsars have no flux density measurement at any frequency. Here, we report the first flux density measurements, spectral indices, pulse profiles, and correlations of the spectral index with pulsar parameters for 19 pulsars employing the Ultra-Wideband Low (UWL) receiver system installed on the Parkes radio telescope. The results for spectral indices of 17 pulsars are in the range between -0.6 and -3.10. The polarization profiles of thirteen pulsars are shown. There is a moderate correlation between the spectral index and spin frequency. For most pulsars detected, the S/N ratio of pulse profile is not high, so DM, Faraday rotation measure (RM), and polarization can not be determined precisely. Twenty-nine pulsars were not detected in our observations. We discuss the possible explanations for why these pulsars were not detected.

description: It is a fundamental, but still elusive question whether the schemes based on quantum mechanics, in particular on quantum entanglement, can be used for classical information processing and machine learning. Even partial answer to this question would bring important insights to both fields of machine learning and quantum mechanics. In this work, we implement simple numerical experiments, related to pattern/images classification, in which we represent the classifiers by many-qubit quantum states written in the matrix product states (MPS). Classical machine learning algorithm is applied to these quantum states to learn the classical data. We explicitly show how quantum entanglement (i.e., single-site and bipartite entanglement) can emerge in such represented images. Entanglement characterizes here the importance of data, and such information are practically used to guide the architecture of MPS, and improve the efficiency. The number of needed qubits can be reduced to less than 1/10 of the original number, which is within the access of the state-of-the-art quantum computers. We expect such numerical experiments could open new paths in charactering classical machine learning algorithms, and at the same time shed lights on the generic quantum simulations/computations of machine learning tasks.
