description: Reported in numbers, international humanitarian organisations’ cash and voucher assistance has grown at an impressive rate, rising from under 8% to 19% of global humanitarian aid in 2021, coming to $6.7 billion dollars. At the same time, the numbers of people on the move continue to rise while the humanitarian aid levels have plateaued at $31.3 billion (2022). To respond to these pressures, humanitarian organisations have intensified their use of digital and communications technology to reach more people, to make aid distribution more efficient, and to monitor how that aid achieves humanitarian objectives. This collection gathers together practitioners, researchers, policymakers, and academics grappling with the intersection of technology, aid, and mobility. We build on four sessions organised by Hanna Ruszczyk, Aila Spathopoulou, Glenda Garelli and Nadine Hassouneh at the 2021 International Humanitarian Studies Association Conference (Paris, 3-5 November 2021) and a workshop organised by Lauren Martin and Hanna Ruszczyk for Durham University’s Institute of Hazard, Risk and Resilience 2022 Annual Conference (Durham, UK, 12 October 2022).

description: We introduce the continuity equation for the electromagnetic spin angular momentum (SAM) in matter and discuss the torque associated with the SAM transfer in terms of effective spin forces acting in a material. In plasmonic metal, these spin forces result in plasmogalvanic phenomenon which is pinning the plasmon-induced electromotive force to atomically-thin layer at the metal interface.

description: Solvent extraction using a microfluidic platform is one of the process intensification tools. It may involve different two-phase flow regimes that have different physical and mass transfer characteristics. Therefore, this study focuses on the selection of a better flow regime, flow conditions and cascade configuration (cross or counter-current) using mathematical modeling for a typical high-throughput application (1000 L/day). The mathematical model is based on a plug flow model. The liquid–liquid system considered is a water–acetone–toluene system. The different flow regimes such as slug flow (SF), slug-droplet flow (SDF) and core-annular flow (CAF) in different cascade configurations are compared on the basis of parameters like specific extraction rate (SER), solvent extraction process effectiveness (SEPE) and modified merit index (MMI). Among the different flow regimes and cases studied, CAF is found to offer lesser parallel paths, total extraction length, total pressure drop and residence time. The best case of CAF has higher SER (3.6 times), SEPE (3.6 times) and MMI (21.8 times) than the best case of SF in both cascades. SDF shows the results between SF and CAF. For a specific flow regime, higher values of parameters are obtained at higher flow rates. Counter-current cascade is found to be better than cross-current cascade.

description: We study a "classical" bouncing scenario in beyond Horndeski theory. We give an example of spatially flat bouncing solution that is non-singular and stable throughout the whole evolution. The model is arranged in such a way that the scalar field driving the cosmological evolution initially behaves like full-fledged beyond Horndeski, whereas at late times it becomes a massless scalar field minimally coupled to gravity.

Final version of advanced autonomous functionalities for aerial robots
Creators: name: PILOTING Project
Publisher: name: Zenodo
Year: 2023

description: This document aims to introduce the final version of algorithms developed for aerial inspection robots that deal with GNSS-free navigation and aerial contact control. This deliverable is a result of the work carried out in tasks T5.1 and T5.3. PILOTING use-cases involve multiple challenges for inspection and maintenance operations using aerial robots, including physical interaction with the environment, drone aerodynamic interactions with nearby surfaces, lack of GNSS signals, unstructured environments, irregular lighting conditions, among others. To overcome these challenges, the proposed I&M Platform features autonomous functionalities that enable aerial robots safely and autonomously complete contact and non-contact inspection missions. The autonomous functionalities for aerial robots are classified into two sets of categories: autonomous control while contacting the surface including autonomous take-off and landing, and autonomous safe navigation in GNSS-denied environments. The autonomous control while contacting the surface is essential as it allows aerial robots to perform advanced physical-contact inspections. These functionalities were developed in task T5.3. The autonomous navigation functionalities enable aerial robots to navigate environments safely and reach desired inspection locations in complex, highly cluttered, unstructured environments. These functionalities were developed in T5.1.

description: We explore for the first time the effect of self-interacting dark matter (SIDM) on the dark matter (DM) and baryonic distribution in massive galaxies formed in hydrodynamical cosmological simulations, including explicit baryonic physics treatment. A novel implementation of Super-Massive Black Hole (SMBH) formation and evolution is used, as in Tremmel et al.(2015, 2016), allowing to explicitly follow SMBH dynamics at the center of galaxies. A high SIDM constant cross-section is chosen, $σ$=10 $\rm cm^2/gr$, to amplify differences from CDM models. Milky Way-like galaxies form a shallower DM density profile in SIDM than they do in CDM, with differences already at 20 kpc scales. This demonstrates that even for the most massive spirals the effect of SIDM dominates over the adiabatic contraction due to baryons. Strikingly, the dynamics of SMBHs differs in the SIDM and reference CDM case. SMBHs in massive spirals have sunk to the centre of their host galaxy in both the SIDM and CDM run, while in less massive galaxies about 80$\%$ of the SMBH population is off-centered in the SIDM case, as opposed to the CDM case in which $\sim$90$\%$ of SMBHs have reached their host's centre. SMBHs are found as far as $\sim$9 kpc away from the centre of their host SIDM galaxy. This difference is due to the increased dynamical friction timescale caused by the lower DM density in SIDM galaxies compared to CDM, resulting in 'core stalling'. This pilot work highlights the importance of simulating in a full hydrodynamical context different DM models combined to SMBH physics to study their influence on galaxy formation.

Necking after extensional filament stretching of complex fluids and soft solids

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We perform linear stability analysis and nonlinear slender filament simulations of extensional necking in complex fluids and soft solids, during the stress relaxation process following an interrupted strain ramp. We start by deriving analytical criteria for necking within a highly simplified and generalised scalar constitutive model. Here, we find two different possible modes of necking: one associated with an upward curvature in the stress relaxation function on a log-linear plot, and another related to a carefully defined `elastic' derivative of the tensile force with respect to an imagined sudden strain increment. We showed these two criteria to agree fully with simulations of the Oldroyd B and Giesekus models of polymeric solutions, and with the RoliePoly model of more concentrated polymeric solutions and melts, without polymer chain stretch. With chain stretch included, we find a slightly more complicated analytical criterion for necking during the stress relaxation, with key ingredients that closely mirror counterpart ingredients of the simpler criteria obtained within the scalar model. We show this criterion to agree fully with slender filament simulations of the RoliePoly model with chain stretch, and with the scenario discussed by the Copenhagen group in Refs. [1, 2]. In particular, we see delayed necking after strain ramps with an accumulated strain exceeding ~ 0.7, for ramp rates exceeding the inverse chain stretch relaxation timescale. We discuss finally an analogy between this delayed necking following an interrupted extensional strain ramp and delayed shear banding following an interrupted shear strain ramp [3]. This work provides the counterpart, for interrupted extensional strain ramps, to earlier papers giving criteria for necking in the protocols of constant imposed Hencky strain rate [4] and of constant imposed tensile stress or constant imposed tensile force [5].

description: A new composite material, named TSC/AXAD-2, was developed by incorporating a bis-thiosemicarbazone derivative (TSC) into Amberlite XAD-2 to extract Pb2+ ions from wastewater. The new composite was characterized using XPS, TGA, FTIR, BET, EDX, 1H-NMR, 13C-NMR, and GC-MS analyses. The sorption parameters, such as pH value of media, equilibrium time, initial Pb2+ ion concentration, composite dose, temperature, and eluting agents, were methodically optimized. The utmost adsorption capacity is 45.3 mg.g−1; it was achieved at pH value of of 5.5, 15 min of agitation, room temperature, and initial concentration of 200 mg.L−1 Pb2+ ions. The isotherm studies revealed that the adsorption process closely matches the Langmuir model, with a theoretical retention capacity of 46.12 mg.g−1. Furthermore, kinetic modeling using the pseudo-first-order accurately depicted the adsorption of Pb2+ ions. The thermodynamic study suggested that the adsorption process is exothermic, spontaneous, and more favorable at lower temperatures. The desorption of Pb2+ ions from the loaded composite was conducted with 1.0 M of either HCl or HNO3. The TSC/AXAD-2 composite successfully met WHO and FAO guidelines for removal of Pb2+ ions from wastewater before its discharge into the marine environment.

description: Three models for nonlocal electron thermal transport are here compared against Vlasov-Fokker-Planck (VFP) codes to assess their accuracy in situations relevant to both inertial fusion hohlraums and tokamak scrape-off layers. The models tested are (i) a moment-based approach using an eigenvector integral closure (EIC) originally developed by Ji, Held and Sovinec; (ii) the non-Fourier Landau-fluid (NFLF) model of Dimits, Joseph and Umansky; and (iii) Schurtz, Nicolaï and Busquet's multigroup diffusion model (SNB). We find that while the EIC and NFLF models accurately predict the damping rate of a small-amplitude temperature perturbation (within 10% at moderate collisionalities), they overestimate the peak heat flow by as much as 35% and do not predict preheat in the more relevant case where there is a large temperature difference. The SNB model, however, agrees better with VFP results for the latter problem if care is taken with the definition of the mean free path. Additionally, we present for the first time a comparison of the SNB model against a VFP code for a hohlraum-relevant problem with inhomogeneous ionisation and show that the model overestimates the heat flow in the helium gas-fill by a factor of ~2 despite predicting the peak heat flux to within 16%.

New Constraints on Dark Matter Production during Kination

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Our ignorance of the period between the end of inflation and the beginning of Big Bang Nucleosynthesis limits our understanding of the origins and evolution of dark matter. One possibility is that the Universe's energy density was dominated by a fast-rolling scalar field while the radiation bath was hot enough to thermally produce dark matter. We investigate the evolution of the dark matter density and derive analytic expressions for the dark matter relic abundance generated during such a period of kination. Kination scenarios in which dark matter does not reach thermal equilibrium require $\langle σv \rangle < 2.7\times 10^{-38} \,\mathrm{cm^3\,s^{-1}}$ to generate the observed dark matter density while allowing the Universe to become radiation dominated by a temperature of $3 \, \mathrm{MeV}$. Kination scenarios in which dark matter does reach thermal equilibrium require $\langle σv \rangle > 3\times 10^{-26} \,\mathrm{cm^3\,s^{-1}}$ in order to generate the observed dark matter abundance. We use observations of dwarf spheroidal galaxies by the Fermi Gamma-Ray Telescope and observations of the Galactic Center by the High Energy Stereoscopic System to constrain these kination scenarios. Combining the unitarity constraint on $\langle σv \rangle$ with these observational constraints sets a lower limit on the temperature at which the Universe can become radiation dominated following a period of kination if ${\langle σv \rangle > 3\times 10^{-31} \,\mathrm{cm^3\,s^{-1}}}$. This lower limit is between ${0.05 \, \mathrm{GeV}}$ and ${1 \, \mathrm{GeV}}$, depending on the dark matter annihilation channel.

This amounts to solving certain systems of exponential sums equations, and it generalizes old results of Zilber, which required stronger assumptions on the variety such as the linear space being defined over the real numbers.

Security of continuous-variable quantum key distribution via a Gaussian de Finetti reduction

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Establishing the security of continuous-variable quantum key distribution against general attacks in a realistic finite-size regime is an outstanding open problem in the field of theoretical quantum cryptography if we restrict our attention to protocols that rely on the exchange of coherent states. Indeed, techniques based on the uncertainty principle are not known to work for such protocols, and the usual tools based on de Finetti reductions only provide security for unrealistically large block lengths. We address this problem here by considering a new type of Gaussian de Finetti reduction, that exploits the invariance of some continuous-variable protocols under the action of the unitary group $U(n)$ (instead of the symmetric group $S_n$ as in usual de Finetti theorems), and by introducing generalized $SU(2,2)$ coherent states. Our reduction shows that it is sufficient to prove the security of these protocols against Gaussian collective attacks in order to obtain security against general attacks, thereby confirming rigorously the widely held belief that Gaussian attacks are indeed optimal against such protocols.

description: Taking into account non-adiabatic effects in stellar pulsation calculations is important because it allows us to determine excitation or damping rates, and is important for obtaining the variations of effective temperature at the surface, which in turn play a key role in mode visibilities. Calculating these effects in rapidly rotating stellar models is a theoretical and numerical challenge due to the complexity of the equations and the stiffness of the numerical system. In the present poster, we describe the latest progress in validating and computing non-adiabatic modes in ESTER models using the TOP pulsation code.

description: In this paper, we discuss the problem of determination of light radiation pressure force upon an anisotropic surface. The optical parameters of such a surface are considered to have major and minor axes, so the model is called an orthotropic model. We derive the equations for force components from emission, absorption, and reflection, utilizing a modified Maxwell's specular-diffuse model. The proposed model can be used to model a flat solar sail with wrinkles. By performing Bayesian analysis for example of a wrinkled surface, we show that there are cases in which an orthotropic model of the optical parameters of a surface may be more accurate than an isotropic model.

The CME, observed as back-to-back charge separation along the magnetic field axis, is investigated using the newly developed Sliding Dumbbell Method (SDM) applied to Au+Au events at a center-of-mass energy $\sqrt{s}_{\mathrm{NN}}$ = 200 GeV generated by the AMPT model with string melting configuration. The CME-like signal is externally injected in events by flipping charges of pairs of the particles perpendicular to the reaction plane. The study reports a significant enhancement of the CME-sensitive 3-particle $γ$ correlator in events with high back-to-back charge separation, in a given collision centrality. Additionally, a linear relationship is observed between the $\sqrt{|γ|}$ correlator for same-sign charge pairs and positive charge asymmetry ($\langle A{^+}\rangle$) across the dumbbell in CME-enriched sub-samples. Furthermore, the fraction of CME in $Δγ$ (difference between opposite and same sign $γ$ correlators) is presented across different collision centralities having different percentages of externally injected CME-like signal. Overall, the research aims to understand and detect the Chiral Magnetic Effect through innovative experimental method and detailed analysis of event structure.

description: Many models of inflation driven by vector fields alone have been known to be plagued by pathological behaviors, namely ghost and/or gradient instabilities. In this work, we seek a new class of vector-driven inflationary models that evade all of the mentioned instabilities. We build our analysis on the Generalized Proca Theory with an extension to three vector fields to realize isotropic expansion. We obtain the conditions required for quasi de-Sitter solutions to be an attractor analogous to the standard slow-roll one and those for their stability at the level of linearized perturbations. Identifying the remedy to the existing unstable models, we provide a simple example and explicitly show its stability. This significantly broadens our knowledge on vector inflationary scenarios, reviving potential phenomenological interests for this class of models.

description: In this paper, we investigate an optimal design problem motivated by some issues arising in population dynamics. In a nutshell, we aim at determining the optimal shape of a region occupied by resources for maximizing the survival ability of a species in a given box and we consider the general case of Robin boundary conditions on its boundary. Mathematically, this issue can be modeled with the help of an extremal indefinite weight linear eigenvalue problem. The optimal spatial arrangement is obtained by minimizing the positive principal eigenvalue with respect to the weight, under a L 1 constraint standing for limitation of the total amount of resources. The specificity of such a problem rests upon the presence of nonlinear functions of the weight both in the numerator and denominator of the Rayleigh quotient. By using adapted symmetrization procedures, a well-chosen change of variable, as well as necessary optimality conditions, we completely solve this optimization problem in the unidimensional case by showing first that every minimizer is unimodal and bang-bang. This leads to investigate a finite dimensional optimization problem. This allows to show in particular that every minimizer is (up to additive constants) the characteristic function of three possible domains: an interval that sticks on the boundary of the box, an interval that is symmetrically located at the middle of the box, or, for a precise value of the Robin coefficient, all intervals of a given fixed length.

description: In recent years, new experimental determinations of numerous nuclear reaction rates relevant for astrophysics have been achieved via direct and indirect experimental methods, highlighting specific trends like the unexpected fusion hindrance phenomenon (steep fall of the fusion cross section at very low energies) and multiple resonances. In particular, a precise determination of the nuclear reaction rates is a crucial ingredient in understanding stellar evolution. New nuclear reaction rates have been determined for the different cycles of H-burning, He-burning and C-burning phases by nuclear experiment, leading to significant changes in the nucleosynthesis, with especially consequences on s-process elements abundances. In order to improve stellar modelling, we now need to take into account these new results that can bring one of the key to understand stellar evolution and especially the chemically peculiar stars. In particular, new direct measurements for the C12+C12 nuclear reaction have been obtained at very low energies by the STELLA collaboration in France (Fruet et al. 2020) and open the way to improvements in stellar evolution modelling. This reaction is indeed the main nuclear reaction during the advanced C-burning phase of massive stars (> 8Msol) and can drive important changes in the lifetime of this phase and in the resulting abundances, impacting later stages of the evolution. Monpribat et al. 2022 showed these new rates impact the burning lifetime as well as the production of C-burning products and s-process elements. Using the stellar evolution codes GENEC and STAREVOL, we computed new models for a larger range of mass and metallicity, and including rotation-induced mixing. We confirm previous preliminary results and highlight increased impact due to rotation as well as the dependence on the stellar mass/metallicity for the production of s-elements and final stages of stars (Dumont et al. 2023, A&A in prep.)

description: The pervasiveness of “impact measurement” platforms like Researchfish are both symptom and cause of the over-metricization of research, and lead to the loss of nuance when thinking about research impact. In this talk, Jorge Gomez Magenti discusses alternatives for a healthier, more responsible research evaluation.

description: We discuss several classes of integrable Floquet systems, i.e. systems which do not exhibit chaotic behavior even under a time dependent perturbation. The first class is associated with finite-dimensional Lie groups and infinite-dimensional generalization thereof. The second class is related to the row transfer matrices of the 2D statistical mechanics models. The third class of models, called here "boost models", is constructed as a periodic interchange of two Hamiltonians - one is the integrable lattice model Hamiltonian, while the second is the boost operator. The latter for known cases coincides with the entanglement Hamiltonian and is closely related to the corner transfer matrix of the corresponding 2D statistical models. We present several explicit examples. As an interesting application of the boost models we discuss a possibility of generating periodically oscillating states with the period different from that of the driving field. In particular, one can realize an oscillating state by performing a static quench to a boost operator. We term this state a "Quantum Boost Clock". All analyzed setups can be readily realized experimentally, for example in cod atoms.
