description: In this paper, we investigate zero-derived nouns based on irregular verbs in Greek. This is an under-explored area in Greek morpho-syntax, and in this paper, we will make three main contributions. First, we will discuss the fact that the overwhelming majority of these nouns are feminine, while neuter nouns are considerably less represented and masculine nouns are almost nonexistent. As feminine is taken to be the semantically marked gender in the case of animate nouns, asserting female sex, and neuter is argued to be the default gender in Greek for inanimates, the fact that zero abstract nouns are feminine is surprising. We will argue that feminine is the default in the case of zero derivation by exploiting an analysis of flavors of n. Second, we will show that, contrary to the findings in earlier literature, certain zero-derived nouns do have argument structure, similarly to their affixed counterparts. As not all zero-derived nouns have argument structure, we will appeal to complex head formation to explain the properties of those zero-derived nouns that have an eventive interpretation but do not surface with arguments. Finally, we will turn to an examination of the size of the domain that is nominalized. Since, in our cases, we observe root allomorphy conditioned by a nominal affix in the presence of a zero verbal head, we will suggest that Pruning is the mechanism that allows this.

PERSEUS

description: PERSEUS is a European project led by students and operated by CNES, the French space agency. The aim is to allow students to engage in space related activities and gain valuable experience that will train them prior to beginning their professional activities in this sector. In this context, the Supaero Space Section technical club of ISAE SUPAERO is involved in the design of the next generation LOX/Ethanol liquid rocket engine MINERVA to be used in the sounding rocket ASTREOS 2 under development. The design of a regenerative cooling system is a building block within the vision of launcher reusability laid out by CNES as part of the evolutions of the Astreos student-built rocket. To carry out this vision, a cooling channel design and optimization tool has been developed with the objective to minimize the pressure losses while keeping the combustion wall temperature under the maximum allowable value and the coolant bulk temperature below saturation. In fact, the main technical challenge is to maintain the coolant below its critical heat flux limit, preserving its heat absorption capability. lD heat transfer has been assumed using hot gas convection and radiation, wall conduction, and coolant convection. To account for nucleate boiling of the ethanol, a two-phase convective heat coefficient is computed along the channel and critical heat is calculated using peer reviewed correlations in the literature. Hot gas and coolant thermodynamic properties were estimated using the NASA RocketCEA and CoolProp libraries respectively. Conservation of mass, momentum and energy of the coolant was guaranteed by implementing the lD Navier-Stokes equations. It is the objective for this tool to be used generically within PERSEUS based on chamber dimensions, propellants and target engine performance.

description: The objective of this work is to develop a sizing tool for impinging and coaxial-type injectors. The tool is built on a database of experimental and theoretical correlations available in the literature for the design of liquid rocket engine injectors. They relate the injector element geometries and propellant properties to the injection pressure losses, liquid droplet size and mixing performance. Doublet impinging, swirl coaxial and shear coaxial element geometries were sized using the tool and presented with their expected respective performances. It is the aim of this work to be a building block for the design of injectors within the PERSEUS project.

MULTI-BODY SEPARATION
OVERSET METHODS

description: Numerical simulations of bodies experiencing large relative motion, as for instance the case of two separating bodies, is a challenging task for Computational Fluid Dynamic, because mesh deformation algorithms might be inapplicable and global re-meshing techniques could be computationally too expensive. For this reason, overset methods using overlapping grids are used to tackle these kind of problems. However, even though the overset techniques are very versatile, the transfer of information between overlapping meshes is an error source that can compromise the numerical solution quality. This work describes a new computational technique, that does not use overlapping meshes, but is instead based on local remeshing and makes only limited use of interpolation between different meshes. Algorithmic details of the aforementioned technique as well as two test-cases involving the separation of bodies in high-speed flows will be presented in this paper.
State-dependence of climate sensitivity: attractor constraints and palaeoclimate regimes

description: Equilibrium climate sensitivity (ECS) is a key predictor of climate change. However, it is not very well constrained, either by climate models or by observational data. The reasons for this include strong internal variability and forcing on many time scales. In practise this means that the 'equilibrium' will only be relative to fixing the slow feedback processes before comparing palaeoclimate sensitivity estimates with estimates from model simulations. In addition, information from the late Pleistocene ice age cycles indicates that the climate cycles between cold and warm regimes, and the climate sensitivity varies considerably between regime because of fast feedback processes changing relative strength and time scales over one cycle. In this paper we consider climate sensitivity for quite general climate dynamics. Using a conceptual Earth system model of Gildor and Tziperman (2001) (with Milankovich forcing and dynamical ocean biogeochemistry) we explore various ways of quantifying the state-dependence of climate sensitivity from unperturbed and perturbed model time series. Even without considering any perturbations, we suggest that climate sensitivity can be usefully thought of as a distribution that quantifies variability within the 'climate attractor' and where there is a strong dependence on climate state and more specificially on the 'climate regime' where fast processes are approximately in equilibrium. We also consider perturbations by instantaneous doubling of CO$_2$ and similarly find a strong dependence on the climate state using our approach.

description: We show theoretically that a photonic topological insulator can support edge solitons that are strongly self-localized and propagate unidirectionally along the lattice edge. The photonic topological insulator consists of a Floquet lattice of coupled helical waveguides, in a medium with local Kerr nonlinearity. The soliton behavior is strongly affected by the topological phase of the linear lattice. The topologically nontrivial phase gives a continuous family of solitons, while the topologically trivial phase gives an embedded soliton that occurs at a single power, and arises from a self-induced local nonlinear shift in the inter-site coupling. The solitons can be used for nonlinear switching and logical operations, functionalities that have not yet been explored in topological photonics. We demonstrate using solitons to perform selective filtering via propagation through a narrow channel, and using soliton collisions for optical switching.

DESIGN PROCESS

description: One of the most stressed components of a liquid rocket engine is the cooling systems of the combustion chamber. A complete 3D model loop for the cooling system thermal dimensioning has been developed and here presented. The main objective of the model is a complete and detailed description of coupled solid/coolant behaviour characterizing the liquid rocket engine cooling systems, such as threedimensional effects, supercritical behaviour of the coolant, thermo-structural behaviour of the solid. The model combines the industrial necessity to obtain proper results in reasonable times with a detailed description of the involved phenomena and specific characteristics of the configuration.

In comparison, the effect of saturation scale and color charge fluctuations is weak.

description: Teleportation protocol is conventionally treated as a method for quantum state transfer between two spatially separated physical carriers. Recent experimental progress in manipulation with high-dimensional quantum systems opens a new framework for implementation of teleportation protocols. We show that the one-qubit teleportation can be considered as a state transfer between subspaces of the whole Hilbert space of an indivisible eight-dimensional system. We explicitly show all corresponding operations and discuss an alternative way of implementation of similar tasks.

In this frame, a model to investigate on the temperature of the injector dome is proposed and analysed in detail. The model consists of two iterative steps integrating the reacting domain and the cold one. The numerical model is composed of a hot domain, in which reacting CFD simulations are performed in the OpenFOAM environment, and of a cold domain, in which RANS compressible steady-state CFD simulations are performed by Ansys Fluent 2023 Rl ([[5]J[6]).

description: The Yule--Simon distribution has been out of the radar of the Bayesian community, so far. In this note, we propose an explicit Gibbs sampling scheme when a Gamma prior is chosen for the shape parameter. The performance of the algorithm is illustrated with simulation studies, including count data regression, and a real data application to text analysis. We compare our proposal to the frequentist counterparts showing better performance of our algorithm when a small sample size is considered.

description: The implementation of efficient multigrid preconditioners for elliptic partial differential equations (PDEs) is a challenge due to the complexity of the resulting algorithms and corresponding computer code. For sophisticated finite element discretisations on unstructured grids an efficient implementation can be very time consuming and requires the programmer to have in-depth knowledge of the mathematical theory, parallel computing and optimisation techniques on manycore CPUs. In this paper we show how the development of bespoke multigrid preconditioners can be simplified significantly by using a framework which allows the expression of the each component of the algorithm at the correct abstraction level. Our approach (1) allows the expression of the finite element problem in a language which is close to the mathematical formulation of the problem, (2) guarantees the automatic generation and efficient execution of parallel optimised low-level computer code and (3) is flexible enough to support different abstraction levels and give the programmer control over details of the preconditioner. We use the composable abstractions of the Firedrake/PyOP2 package to demonstrate the efficiency of this approach for the solution of strongly anisotropic PDEs in atmospheric modelling. The weak formulation of the PDE is expressed in Unified Form Language (UFL) and the lower PyOP2 abstraction layer allows the manual design of computational kernels for a bespoke geometric multigrid preconditioner. We compare the performance of this preconditioner to a single-level method and hypre's BoomerAMG algorithm. The Firedrake/PyOP2 code is inherently parallel and we present a detailed performance analysis for a single node (24 cores) on the ARCHER supercomputer. Our implementation utilises a significant fraction of the available memory bandwidth and shows very good weak scaling on up to 6,144 compute cores.

description: In this paper, we investigate cosmological consequences of a scenario for recently reported accelerated expansion of the Universe, in which the generalized Chaplygin gas (GCG) along with the baryonic matter are responsible for this observed phenomenon. In the present model, we employ an isotropic and homogeneous FLRW space time in the framework of $f(R,T)$ theory of gravity. In $f(R,T)$ gravity, the conservation of energy-momentum tensor (EMT) leads to a constraint equation which enforces us to use some specific forms of type $f(R,T)=g(R)+h(T)$. In this work we choose $g(R)=R$. We consider three classes of Chaplygin gas models which include three different forms of $f(R,T)$ function; those models which employ the standard Chaplygin gas (SCG), models which use GCG in the high pressure regimes and finally, the third case is devoted to investigating high density regimes in the presence of GCG.

description: Fast Radio Bursts have recently been used to place limits on Einstein's Equivalence Principle via observations of time delays between photons of different radio frequencies by \citet{wei15}. These limits on differential post-Newtonian parameters ($Δγ<2.52\times10^{-8}$) are the best yet achieved but still rely on uncertain assumptions, namely the relative contributions of dispersion and gravitational delays to the observed time delays and the distances to FRBs. Also very recently, the first FRB host galaxy has likely been identified, providing the first redshift-based distance estimate to FRB 150418 \citep{kea16}. Moreover, consistency between the \omegaigm\ estimate from FRB 150418 and \omegaigm~expected from $Λ$CDM models and WMAP observations leads one to conclude that the observed time delay for FRB 150418 is highly dominated by dispersion, with any gravitational delays small contributors. This points to even tighter limits on $Δγ$. In this paper, the technique of \citet{wei15} is applied to FRB 150418 to produce a limit of $Δγ< 1 - 2\times10^{-9}$, approximately an order of magnitude better than previous limits and in line with expectations by \citet{wei15} for what could be achieved if the dispersive delay is separated from other effects. Future substantial improvements in such limits will depend on accurately determining the contribution of individual ionized components to the total observed time delays for FRBs.

This paper focuses on the combustion visualization of a paraffin-based fuel grain burning with oxygen at different pressure and oxidizer mass flux. After a short overview of the experimental setup and the improvements over previous works, some images acquired during two different test campaign are shown, and the main features of paraffin combustion identified in the videos are discussed. Finally, a qualitative discussion of the effect of the pressure and oxidizer mass flux on the observed flame thickness and brightness is provided.

description: Milz and Strunz ({\it J. Phys. A}: {\bf{48}} [2015] 035306) recently studied the probabilities that two-qubit and qubit-qutrit states, randomly generated with respect to Hilbert-Schmidt (Euclidean/flat) measure, are separable. They concluded that in both cases, the separability probabilities (apparently exactly $\frac{8}{33}$ in the two-qubit scenario) hold {\it constant} over the Bloch radii ($r$) of the single-qubit subsystems, jumping to 1 at the pure state boundaries ($r=1$). Here, firstly, we present evidence that in the qubit-qutrit case, the separability probability is uniformly distributed, as well, over the {\it generalized} Bloch radius ($R$) of the qutrit subsystem. While the qubit (standard) Bloch vector is positioned in three-dimensional space, the qutrit generalized Bloch vector lives in eight-dimensional space. The radii variables $r$ and $R$ themselves are the lengths/norms (being square roots of {\it quadratic} Casimir invariants) of these ("coherence") vectors. Additionally, we find that not only are the qubit-qutrit separability probabilities invariant over the quadratic Casimir invariant of the qutrit subsystem, but apparently also over the {\it cubic} one--and similarly the case, more generally, with the use of random induced measure. We also investigate two-qutrit ($3 \times 3$) and qubit-{\it qudit} ($2 \times 4$) systems--with seemingly analogous {\it positive-partial-transpose}-probability invariances holding over what have been termed by Altafini, the {\it partial} Casimir invariants of these systems.

description: The present work represents the first step toward a new layout for the nuclear propulsion systems. The regenerative cooled nozzle present in the historic configuration is eliminated from the system and replaced with several small er nozzles shaped inside each core\'s coolant channels. The focus of this study is the determination of the channel\'s optimum geometry for a general fuel element and the corresponding power density distribution. These outputs are achieved by implementing a new methodology for solving the ID steady viscous and non-adiabatic duct flow equations by imposing the Mach number and the wall outer temperature profiles as boundary conditions.

description: The early evolution of low mass stars during the classical T Tauri phase depends on the interaction between the star and its accretion disc, on distances of few stellar radii. The star-disc interaction is responsible for accretion and ejection phenomena that have a strong impact on spectral lines formed in the close vicinity of the star's surface. The comparison between radiative transfer modelling of spectral lines formed in the star- disc interaction region with observations can give constraints on the physics of accretion and ejection. In particular, near infrared spectro- interferometric observations of the Brackett gamma line is a promising tool to characterise the magnetospheric accretion region.

description: Traditional graph-based semi-supervised learning (SSL) approaches, even though widely applied, are not suited for massive data and large label scenarios since they scale linearly with the number of edges $|E|$ and distinct labels $m$. To deal with the large label size problem, recent works propose sketch-based methods to approximate the distribution on labels per node thereby achieving a space reduction from $O(m)$ to $O(\log m)$, under certain conditions. In this paper, we present a novel streaming graph-based SSL approximation that captures the sparsity of the label distribution and ensures the algorithm propagates labels accurately, and further reduces the space complexity per node to $O(1)$. We also provide a distributed version of the algorithm that scales well to large data sizes. Experiments on real-world datasets demonstrate that the new method achieves better performance than existing state-of-the-art algorithms with significant reduction in memory footprint. We also study different graph construction mechanisms for natural language applications and propose a robust graph augmentation strategy trained using state-of-the-art unsupervised deep learning architectures that yields further significant quality gains.

description: A gravitationally collapsed object can bounce-out from its horizon via a tunnelling process that violates the classical equations in a finite region. Since tunnelling is a non-perturbative phenomenon, it cannot be described in terms of quantum fluctuations around a classical solution and a background-free formulation of quantum gravity is needed to analyze it. Here we use Loop Quantum Gravity to compute the amplitude for this process, in a first approximation. The amplitude determines the tunnelling time as a function of the mass. This is the key information to evaluate the astrophysical relevance of this process. The calculation offers a template and a concrete example of how a background-free quantum theory of gravity can be used to compute a realistical observable quantity.

$A_4 \times U(1)_{PQ}$ Model for the Lepton Flavor Structure and the Strong $CP$ Problem

description: We present a model with $A_4 \times U(1)_{PQ}$ lepton flavor symmetry which explains the origin of the lepton flavor structure and also solves the strong $CP$ problem. Standard model gauge singlet fields, so-called "flavons", charged under the $A_4 \times U(1)_{PQ}$ symmetry are introduced and are coupled with the lepton and the Higgs sectors. The flavon vacuum expectation values (VEVs) trigger spontaneous breaking of the $A_4 \times U(1)_{PQ}$ symmetry. The breaking pattern of the $A_4$ accounts for the tri-bimaximal neutrino mixing and the deviation from it due to the non-zero $θ_{13}$ angle, and the breaking of the $U(1)_{PQ}$ gives rise to a pseudo-Nambu-Goldstone boson, axion, whose VEV cancels the QCD $θ$ term. We investigate the breaking of the $A_4 \times U(1)_{PQ}$ symmetry through an analysis on the scalar potential and further discuss the properties of the axion in the model, including its decay constant, mass and coupling with photons. It is shown that the axion decay constant is related with the right-handed neutrino mass through the flavon VEVs. Experimental constraints on the axion and their implications are also studied.

description: Der Repetition-induced Truth Effect beschreibt, dass Menschen dazu neigen, wiederholte Aussagen eher als wahr einzuschätzen als neue Aussagen. Unsere Studie befasst sich mit der Frage, ob der Repetition-induced Truth Effect unabhängig von der Glaubwürdigkeit der Quelle eines Statements auftritt und ob die Art der Quelle und die Wiederholung von Statements einen Einfluss auf die Reposting-Aktivität der Proband:innen in einem Social?Media Kontext haben. Es wurden bereits einige Studien zum Repetition-induced Truth Effect im Zusammenhang mit der Kredibilität von Quellen durchgeführt. Beispielsweise haben Nadarevic et al. (2020) den Einfluss von fingierten Zeitungsquellen im Vergleich zu reliablen, real existierenden Zeitungsquellen auf die subjektive Wahrheitseinschätzung untersucht. Da die Glaubwürdigkeit von Quellen gerade im Bereich von Social Media eine große Rolle spielt, stützen wir uns auf Studie 3 aus Nadarevic et al. (2020) und wollen die Glaubwürdigkeit von Aussagen von real existierenden, aber den Versuchspersonen unbekannten Zeitungsquellen und Laien-Quellen in einem realistischen Social Media-Kontext untersuchen.

description: We derive an explicit bound on the dimension of the lightest charged state in two dimensional conformal field theories with a global abelian symmetry. We find that the bound scales with $c$ and provide examples that parametrically saturate this bound. We also prove than any such theory must contain a state with charge-to-mass ratio above a minimal lower bound. We comment on the implications for charged states in three dimensional theories of gravity.

description: Vibrational problems in aircraft are of great importance for the comfort and well-being of occupants. In this work, a preliminary experimental campaign is carried out using a full flight simulator to obtain measurements of the acceleration transmitted from the seat to the passengers during some selected flight segments. It considers the take-off including the initial climb, the final approach including the touchdown, and two cruise segments with and without turbulence effects. Specifically for the cruise phase, the power spectral density calculated from the seat surface accelerations was compared with literature and real flight data to verify the simulator\'s capability. The comfort indexes are calculated according to the current ISO 2631 standard for characterizing the effects of vibrations. Two types of seat configurations are studied. The results conclude that the evaluation of comfort indexes in an advanced simulated environment, not merely based on objective data, can contribute to the research of new comfortable scenarios inside the cabin.
