description: No abstracts are to be cited without prior reference to the author.In March 2010, The Crown Estate announced the leasing of several sites for development of the marine energy sector. Included is a large coastal section of West Mainland Orkney (WMO) where leases for wave energy converting devices (WECs) deployment have been granted. As part of a long-term monitoring programme, we have incorporated boat and shore-based field methodologies to complete the first comprehensive assessment of intertidal communities on this coast, serving as a baseline against which long-term ecological changes can be measured. Owing to difficulties of access, the biological community of much of this coastline has never been adequately described.The nearshore ecology off WMO is typified by a highly productive and biodiverse forest of Laminaria hyperborea growing on rock platforms dipping westerly towards the dominant wave direction. Farther offshore, the kelp thins and transitions to an animal-dominated community and, with increasingly deeper waters, to mobile sediments. The interaction between sublittoral topography and dissipation of wave energy approaching the shore is a major determinant in the composition of the benthic community. Along with depth, heterogeneity of the community is produced by topographic variables such as slope, aspect, and complicating features, e.g. reefs and gullies. The effects of removal of energy by WECs might be expected to be most readily observable in the littoral and nearshore marine environment. Video imagery of the sublittoral biological community was captured using an ROV, enabling biotope identification georeferenced to multi-beam and side-scan bathymetric data. Information on waves and currents from hydrodynamic models can be used alongside these data to understand the relationship between topography, wave energy and the benthic community.

description: In this article we apply the holographic principle for describing in a unifying way the early and the late-time universe, when the general equation of state contains a bulk viscosity. We use the idea of a generalized cut-off holographic dark energy introduced by Nojiri and Odintsov (2006,2017), and study the evolution of the universe when the equation of state has two power-law asymptotes. Analytical expressions for the infrared cut-offs in terms of the particle horizon are obtained. The energy conservation laws as derived from the holographic point of view, are given for various forms of the thermodynamic parameters and for various forms of the bulk viscosity. As a result, we obtain a unifying description of the early and the late-time universe in the presence of a viscous holographic fluid.

description: The loss of time-translational invariance caused by a time-dependent external agent leads to particle creation effects in quantum field theory. This phenomenon results in ambiguities when selecting the quantum vacuum of the canonical quantization. In this work we analyze how the time evolution of the number of created particles depends on these ambiguities when external agents are spatially homogeneous. In particular, we generalize the standard quantum Vlasov equation in order to accommodate in its formulation the possibility of having different choices of vacuum, including adiabatic vacua. This study leads us to propose a new physical criterion stronger than the unitary implementation of the dynamics in order to reduce the quantization ambiguities.

description: In this work, we study the impact of electroweak and Higgs precision measurements at future electron-positron colliders on several typical supersymmetric models, including the Constrained Minimal Supersymmetric Standard Model (CMSSM), Non-Universal Higgs Mass generalisations (NUHM1, NUHM2), and the 7-dimensional Minimal Supersymmetric Standard Model (MSSM7). Using publicly-available data from the \textsf{GAMBIT} community, we post-process previous SUSY global fits with additional likelihoods to explore the discovery potential of Higgs factories, such as the Circular Electron Positron Collider (CEPC), the Future Circular Collider (FCC) and the International Linear Collider (ILC). We show that the currently allowed parameter space of these models will be further tested by future precision measurements. In particular, dark matter annihilation mechanisms may be distinguished by precise measurements of Higgs observables.

description: Time-series photometry in I and J band of 57 inner Galactic late-type stars, highly-probable red supergiant (RSG) stars, is here presented. 38% of the sample presents significant photometric variations. The variations in I and J band appear to be correlated, with DeltaI = DeltaJ x 2.2, DeltaI variations ranging from 0.04-1.08 mag, DeltaJ variations from 0.03-0.52 mag. New short periods (< 1000 d) could be estimated for 8 stars and range from 167-433 d. This work confirms that the sample is not contaminated by large-amplitude Asymptotic Giant Branch (AGB) stars. Furthermore, despite the large errors in distance, the period-luminosity diagram suggests that the sample is populating the same sequence as the known Galactic RSGs.

description: We report the detection of fulvenallene ($c$-C$_5$H$_4$CCH$_2$) in the direction of TMC-1 with the QUIJOTE line survey. Thirty rotational transitions with $K_a$=0,1,2,3 and $J$=9-15 were detected. The best rotational temperature fitting of the data is 9\,K and a derived column density is (2.7$\pm$0.3)$\times$10$^{12}$ cm$^{-2}$, which is only a factor of 4.4 below that of its potential precursor cyclopentadiene ($c$-C$_5$H$_6$), and 1.4--1.9 times higher than that of the ethynyl derivatives of cyclopentadiene. We searched for fulvene ($c$-C$_5$H$_4$CH$_2$), a CH$_2$ derivative of cyclopentadiene, for which we derive a 3$σ$ upper limit to its column density of (3.5$\pm$0.5)$\times$10$^{12}$ cm$^{-2}$. Upper limits were also obtained for toluene (C$_6$H$_5$CH$_3$) and styrene (C$_6$H$_5$C$_2$H$_3$), the methyl and vinyl derivatives of benzene. Fulvenallene and ethynyl cyclopentadiene are likely formed in the reaction between cyclopentadiene ($c$-C$_5$H$_6$) and the ehtynyl radical (CCH). However, the bottom-up gas-phase synthesis of cycles in TMC-1 underestimates the abundance of cyclopentadiene by two orders of magnitude, which strengthens the need to study all possible chemical pathways to cyclisation in cold dark cloud environments, such as TMC-1. However, the inclusion of the reaction between C$_3$H$_3^+$ and C$_2$H$_4$ produces a good agreement between model and observed abundances.

description: The contribution introduces a method for the distributed process modelling in order to support the process orientation in Structural Engineering, i.e., the modelling, analysis and management of planning processes. The approach is based on the Petri Net theory for the modelling of planning processes and workflows in Structural Engineering. Firstly, a central and coarse process model serves as a pre-structuring system for the detailed modelling of the technical planning activities. Secondly, the involved planning participants generate distributed process models with detailed technical workflow information. Finally, these distributed process models will be combined in the central workflow net. The final net is of great importance for the process orientation in Structural Engineering, i.e., the identification, publication, analysis, optimization and finally the management of planning processes.

description: No abstracts are to be cited without prior reference to the author.The Norwegian seabed mapping project MAREANO has collected and analysed sea floor video records and sediment samples from the Barents Sea and the Norwegian Sea since 2005. MAREANO maps both conspicuous habitats and general biotopes. This is based on quantitative analyses and classification of megafauna composition recorded on video. Biological classes or biotopes are then modeled for their spatial distribution. Several approaches, both at analysis and classification stages used in the MAREANO programme are presented. Vulnerable biotopes are characterised by combinations of certain habitat-forming large sessile species and represents a “top-down” definition strategy, while the definition of general biotopes by classification of a great number of species represents a “bottom-up approach. There are benefits and limitations associated with the different methods. These will be discussed with focus on the standardizing and naming of the classes of seabed biotopes in deep waters.

Two emitters coupled to a bath with Kerr-like non-linearity: Exponential decay, fractional populations, and Rabi oscillations

description: We consider two non-interacting two-level emitters that are coupled weakly to a one-dimensional non-linear wave guide. Due to the Kerr-like non-linearity, the wave guide considered supports -- in addition to the scattering continuum -- a two-body bound state. As such, the wave guide models a bath with non-trivial mode structure. Solving the time-dependent Schrödinger equation, the radiation dynamics of the two emitters, initially prepared in their excited states, is presented. Changing the emitter frequency such that the two-emitter energy is in resonance with one of the two-body bound states, radiation dynamics ranging from exponential decay to fractional populations to Rabi oscillations is observed. Along with the detuning, the dependence on the separation of the two emitters is investigated. Approximate reduced Hilbert space formulations, which result in effective emitter-separation and momentum dependent interactions, elucidate the underlying physical mechanisms and provide an avenue to showcase the features that would be absent if the one-dimensional wave guide did not contain a non-linearity. Our theoretical findings apply to a number of experimental platforms and the predictions can be tested with state-of-the-art technology. In addition, the weak-coupling Schrödinger equation based results provide critical guidance for the development of master equation approaches.

description: We study five intermediate-age and old open clusters - NGC 7789, NGC 6819, Trumpler 5, Collinder 261, and Berkeley 39 - previously classified as Family I (dynamically young) based on their normalized BSS radial distributions. Using the machine-learning based algorithm, ML-MOC, on the Gaia eDR3 data, we identify their members to investigate dynamical evolution of these clusters using various stellar populations. We find that the five clusters are at different stages of dynamical evolution. Whereas two of the clusters, NGC 7789 and Trumpler 5, are indeed found to be dynamically young based on the cumulative radial distributions of various stellar populations, the remaining three clusters, NGC 6819, Berkeley 39, and Collinder 261, are found to be dynamically evolved with clear mass segregation observed in the radial distributions. We discuss our findings and compare our results with the other observed and theoretical estimates of mass segregation in these clusters.

description: Black hole shadow and gravitational lensing play important roles in testing gravitational theories in the strong field regime. As the first-order modifications from quantum gravity, the nonlocality can be manifested by black hole shadow and gravitational lensing. For example, the cut-off parameter introduced by nonlocality will affect the shape and size of the black hole shadow, and also affect the deflection angle of light rays. In this paper, we mainly investigate the effects of the nonlocality on the black hole shadow and the gravitational lensing for two types of rotating black holes in nonlocal gravity. It is found that the size of the black hole shadow decreases with the cut-off parameter since the nonlocality weakens the gravitational constant, and the shape of the shadow gets more deformed with the increase of the cut-off parameter. However, if the rotation parameter is small, the shape of the shadow is almost a circle even though the cut-off parameter approaches its maximum. The energy emission rate in both models is also studied. The results show that there is a peak for each curve and the peak decreases and shifts to the low frequency with the increase of the cut-off parameter. Besides, we also explore the shadow of both types of black holes surrounded by a nonmagnetized pressureless plasma which satisfies the separability condition. It is found that the plasma has a frequency-dependent dispersive effect on the size and shape of the black hole shadow. For the gravitational lensing, we find that the cut-off parameter of model A makes a positive contribution to the deflection angle, which can be compared with the contribution of the rotation parameter, while the cut-off parameter of model B makes a negative contribution which can be ignored. These results may be helpful for probing nonlocal gravity in future observations.

description: We study a multiorbital Hubbard model coupled to local Jahn-Teller phonons to investigate the superconducting state realized in fullerides. A weak-coupling approach is employed in combination with a local self-energy approximation. In addition to the normal and anomalous self-energies of the electrons, we consider the phonon self-energy, which allows a self-consistent treatment of the energetics. The frequency dependence of the self-energies and their characteristic coefficients, such as renormalization factors and dampings, are investigated in detail using numerical calculations. It is clarified that the anisotropic phonons play an important role in the stabilization of the superconducting state. By comparing the full results to those without phonon self-energies, we show that the superconductivity is stabilized by the softening of the phonon frequency. The effects of electronic fluctuations are also considered, which leads to the coupling to orbitons, an analog of plasmons in the electron gas. This additional contribution further stabilizes the superconducting state.

archaeological prospection

description: Geophysical prospection currently stands as a powerful method in archaeology to study sites in a non-destructive and
 minimally invasive manner. In the last decade, major technological developments have delivered more compact sensors,
 multi-arrays systems, as well as motorised or robotised ground or aerial platforms that are revolutionising archaeological
 research. These technological breakthroughs have allowed the implementation of extremely fast and high-resolution surveys to discover, explore, record and monitor sub-surface archaeological sites and landscapes. Geophysical techniques have been employed in archaeological research for decades and the result has been their steady establishment as routine procedures in cultural heritage management (CHM). However, the use of archaeo-geophysics, both in research and CHM, faces an unbalanced adoption across European countries but also in the rest of the world. Why? What are the experiences or challenges? How can we promote the uptake of geophysical approaches there with little or no-experience of their use? To promote an adequate use of geophysics in archaeological research as well as to advance in geophysical data interpretation beyond basic prospection (presence/absence of possible archaeological features), the Soil science & Archaeo-Geophysics Alliance (SAGA) was funded by the EU COST Association. COST Action SAGA (CA17131) is a research network, which brings together archaeologists, geophysicists and soil scientists from 36 countries. This session is organised under the auspices of COST Action SAGA and is open for contributions (overviews or case-study papers) from SAGA and WAC members, or other external participants working in archaeo-geophysics in research, management or commercial environments, all around the world. We aim to exchange experiences, discuss common and/or specific challenges and solutions, and identify pathways to facilitate the adoption of archaeo-geophysics especially in those countries with high needs- and where the expertise and infrastructures are not readily available.

description: In this paper we consider multi-agent coalitional games with uncertain value functions for which we establish distribution-free guarantees on the probability of allocation stability, i.e., agents do not have incentives to defect from the grand coalition to form subcoalitions for unseen realizations of the uncertain parameter. In case the set of stable allocations, the so called core of the game, is empty, we propose a randomized relaxation of the core. We then show that those allocations that belong to this relaxed set can be accompanied by stability guarantees in a probably approximately correct fashion. Finally, numerical experiments corroborate our theoretical findings.

description: In this paper we demonstrate a sufficient condition for blowup of the nonlinear Klein-Gordon equation with arbitrarily positive initial energy in Friedmann-Lemaître-Robertson-Walker spacetimes. This is accomplished using an established concavity method that has been employed for similar PDEs in Minkowski space. This proof relies on the energy inequality associated with this equation, $E(t_0)\geq E(t)$, also proved herein using a geometric method.

description: A configuration of a test magnetic field in Hayward spacetime is obtained by solving Maxwell's equation with the Hayward metric as the background. The magnetic field lines show a dipole loop-like configuration in the regular Hayward interior, and tends to an asymptotically uniform structure away from the cylindrical axis. The motion of charged particles is then studied in this spacetime. The parameters and stability of circular orbits on the equatorial plane are studied. Aspects of non-equatorial motion are also studied.

description: This paper experimentally investigated the effects of silicone oil on the tribological behaviour of AZ31B/86CrMoV7 contact pair under a pin-on-disk configuration. A commercial silicone oil was used as an oxidation inhibiter for the AZ31B at elevated temperatures to 300 oC. The wear mechanism of the contact pair was explored by SEM morphologies of worn surfaces. The analysis revealed that silicone oil can effectively minimize surface oxidation. Compared with dry sliding, silicone oil can considerably lower down the friction coefficient and specific wear rate. Under lubrication, the abrasive wear at a lower temperature can transit to the combined wear of abrasion, fatigue and adhesion when the temperature rises.

Insight into ground-state spin arrangement and bipartite entanglement of the polymeric coordination compound [Dy$_2$Cu$_2$]$_n$ through the symmetric spin-1/2 Ising-Heisenberg orthogonal-dimer chain

description: The ground-state spin arrangement and the bipartite entanglement within Cu$^{2+}$-Cu$^{2+}$ dimers across the magnetization process of the 4f-3d heterometallic coordination polymer [{Dy(hfac)$_2$(CH$_3$OH)}$_2${Cu(dmg)(Hdmg)}$_2$]$_n$ (H$_2$dmg = dimethylglyoxime, Hhfac = 1,1,1,5,5,5-hexafluoropentane-2,4-dione) are theoretically examined using the symmetric isotropic spin-$1/2$ Ising-Heisenberg orthogonal-dimer chain. The numerical results point to five possible ground states of the compound with three different degrees of the quantum entanglement within Cu$^{2+}$-Cu$^{2+}$. Besides the standard ferrimagnetic and saturated phases without quantum entanglement of Cu$^{2+}$ ions, which are manifested in low-temperature magnetization curve as wide plateaus at the non-saturated magnetization $16.26μ_{\rm B}$ and at the saturation value $20.82μ_{\rm B}$, respectively, one also finds an intriguing singlet-like phase with just partial entanglement within Cu$^{2+}$-Cu$^{2+}$ and two singlet phases with fully entangled Cu$^{2+}$-Cu$^{2+}$ dimers. The former quantum phase can be identified in the low-temperature magnetization process as very narrow intermediate plateau at the magnetization $9.27μ_{\rm B}$ per unit cell, while the latter ones as zero magnetization plateau and intermediate plateau at the magnetization $18.54μ_{\rm B}$. Non-monotonous temperature variations of the concurrence, through which the entanglement within cooper dimers is quantified, point to the possible temporary thermal activation of the entangled states of Cu$^{2+}$-Cu$^{2+}$ also above non-entangled ferrimagnetic and saturated phases.
