description: Context. The HI distribution at high Galactic latitudes is found to be filamentary and closely related to the far infrared (FIR) in caustics with coherent velocity structures. These structures trace the orientation of the magnetic field lines. Aims. Recent absorption observations with the Australian SKA Pathfinder Telescope have led to major improvements in our understanding of the physical properties of the cold neutral medium (CNM) at high Galactic latitudes. We use these results to explore how far the physical state of the CNM may be related with caustics in HI and FIR. Methods. We trace filamentary FIR and HI structures and probe the absorption data for coincidences in position and velocity. Results. 57 percent of the absorption positions are associated with known FIR/HI caustics, filamentary dusty structures with a coherent velocity field. The remaining part of the absorption sample is coincident in position and velocity with genuine HI filaments that are closely related to the FIR counterparts. Thus, within the current sensitivity limitations, all of the positions with HI absorption lines are associated with filamentary structures in FIR and/or HI. We summarize physical parameters for then CNM along filaments in the framework of filament velocities that have been determined from a Hessian analysis of FIR and HI emission data. Velocity deviations between absorption components and filament velocities are due to local turbulence and we determine for the observed CNM an average turbulent velocity dispersion of 2.48 < delta_vturb < 3.9 km/s. The CNM has a mean turbulent Mach number of Mt = 3.4 +/- 1.6 km/s. Conclusions. Most, if not all, of the CNM in the diffuse ISM at high Galactic latitudes is located in filaments, identified as caustics with the Hessian operator.

description: Linear wave equations sourced by a Dirac delta distribution $δ(x)$ and its derivative(s) can serve as a model for many different phenomena. We describe a discontinuous Galerkin (DG) method to numerically solve such equations with source terms proportional to $\partial^n δ/\partial x^n$. Despite the presence of singular source terms, which imply discontinuous or potentially singular solutions, our DG method achieves global spectral accuracy even at the source's location. Our DG method is developed for the wave equation written in fully first-order form. The first-order reduction is carried out using a distributional auxiliary variable that removes some of the source term's singular behavior. While this is helpful numerically, it gives rise to a distributional constraint. We show that a time-independent spurious solution can develop if the initial constraint violation is proportional to $δ(x)$. Numerical experiments verify this behavior and our scheme's convergence properties by comparing against exact solutions.

description: Calculations of the effects of band structure on the neutron superfluid density in the crust of neutron stars made under the assumption that the effects of pairing are small [N. Chamel, Phys. Rev. C 85, 035801 (2012)] lead to moments of inertia of superfluid neutrons so small that the crust alone is insufficient to account for the magnitude of neutron star glitches. Inspired by earlier work on ultracold atomic gases in an optical lattice, we investigate fermions with attractive interactions in a periodic lattice in the mean-field approximation. The effects of band structure are suppressed when the pairing gap is of order or greater than the strength of the lattice potential. By applying the results to the inner crust of neutron stars, we conclude that the reduction of the neutron superfluid density is considerably less than previously estimated and, consequently, it is premature to rule out models of glitches based on neutron superfluidity in the crust.

description: We report on the unusual behavior of the in-plane thermal conductivity ($κ$) and torque ($τ$) response in the Kitaev-Heisenberg material $α$-RuCl$_3$. $κ$ shows a striking enhancement with linear growth beyond H = 7 T, where magnetic order disappears, while $τ$ for both of the in-plane symmetry directions shows an anomaly at the same field. The temperature- and field-dependence of $κ$ are far more complex than conventional phonon and magnon contributions, and require us to invoke the presence of unconventional spin excitations whose properties are characteristic of a field-induced spin-liquid phase related to the enigmatic physics of the Kitaev model in an applied magnetic field

Discontinuous transition from direct to inverse cascade in three-dimensional turbulence

description: Inviscid invariants of flow equations are crucial in determining the direction of the turbulent energy cascade. In this work we investigate a variant of the three dimensional Navier-Stokes equations that shares exactly the same ideal invariants (energy and helicity) and the same symmetries (under rotations, reflexions and scale transforms) as the original equations. It is demonstrated that the examined system displays a change in the direction of the energy cascade when varying the value of a free parameter which controls the relative weights of the triadic interactions between different helical Fourier modes. The transition from a forward to inverse cascade is shown to occur at a critical point in a discontinuous manner with diverging fluctuations close to criticality. Our work thus supports the observation that purely isotropic and three dimensional flow configurations can support inverse energy transfer when interactions are altered and that inside all turbulent flows there is a competition among forward and backward transfer mechanism which might lead to multiple energy-containing turbulent states.

description: The majority of the Milky Way's stellar halo consists of debris from our Galaxy's last major merger, the Gaia-Sausage-Enceladus (GSE). In the past few years, stars from GSE have been kinematically and chemically studied in the inner $30$ kpc of our Galaxy. However, simulations predict that accreted debris could lie at greater distances, forming substructures in the outer halo. Here we derive metallicities and distances using Gaia DR3 XP spectra for an all-sky sample of luminous red giant stars, and map the outer halo with kinematics and metallicities out to $100$ kpc. We obtain follow-up spectra of stars in two strong overdensities - including the previously identified Outer Virgo Overdensity - and find them to be relatively metal-rich and on predominantly retrograde orbits, matching predictions from simulations of the GSE merger. We argue that these are apocentric shells of GSE debris, forming $60-90$ kpc counterparts to the $15-20$ kpc shells that are known to dominate the inner stellar halo. Extending our search across the sky with literature radial velocities, we find evidence for a coherent stream of retrograde stars encircling the Milky Way from $50-100$ kpc, in the same plane as the Sagittarius stream but moving in the opposite direction. These are the first discoveries of distant and structured imprints from the GSE merger, cementing the picture of an inclined and retrograde collision that built up our Galaxy's stellar halo.

description: We present a new database of $>$300 layer-orientations from sedimentary mounds on Mars. These layer orientations, together with draped landslides, and draping of rocks over differentially-eroded paleo-domes, indicate that for the stratigraphically-uppermost $\sim$1 km, the mounds formed by the accretion of draping strata in a mound-shape. The layer-orientation data further suggest that layers lower down in the stratigraphy also formed by the accretion of draping strata in a mound-shape. The data are consistent with terrain-influenced wind erosion, but inconsistent with tilting by flexure, differential compaction over basement, or viscoelastic rebound. We use a simple landscape evolution model to show how the erosion and deposition of mound strata can be modulated by shifts in obliquity. The model is driven by multi-Gyr calculations of Mars' chaotic obliquity and a parameterization of terrain-influenced wind erosion that is derived from mesoscale modeling. Our results suggest that mound-spanning unconformities with kilometers of relief emerge as the result of chaotic obliquity shifts. Our results support the interpretation that Mars' rocks record intermittent liquid-water runoff during a $>$10$^8$-yr interval of sedimentary rock emplacement.

description: We consider $n\times n$ real-valued matrices $A = (a_{ij})$ satisfying $a_{ii} \geq a_{i,i+1} \geq \dots \geq a_{in} \geq a_{i1} \geq \dots \geq a_{i,i-1}$ for $i = 1,\dots,n$. With such a matrix $A$ we associate a directed graph $G(A)$. We prove that the solutions to the system $A^T x = λe$, with $λ\in \mathbb{R}$ and $e$ the vector of all ones, are linear combinations of 'fundamental' solutions to $A^T x=e$ and vectors in $\ker A^T$, each of which is associated with a closed strongly connected component (SCC) of $G(A)$. This allows us to characterize the sign of $\det A$ in terms of the number of closed SCCs and the solutions to $A^T x = e$. In addition, we provide conditions for $A$ to be a $P$-matrix.

description: We present Nuclear Spectroscopic Telescope Array (NuSTAR) hard X-ray timing and spectroscopy of the three exceptionally energetic rotation-powered millisecond pulsars PSRs B1821-24, B1937+21, and J0218+4232. By correcting the NuSTAR onboard clock for phase and frequency drifts between observation intervals, we are able to recover the intrinsic hard X-ray pulse profiles of all three pulsars with a resolution down to < 15 microsec. The substantial reduction of background emission relative to previous broadband X-ray observations allows us to detect for the first time pulsed emission up to ~50 keV, ~20 keV, and ~25 keV, for the three pulsars, respectively. We conduct phase-resolved spectroscopy in the 0.5-79 keV range for all three objects, obtaining the best measurements yet of the broad-band spectral shape and high-energy pulsed emission to date. We find extensions of the same power-law continua seen at lower energies, with no evidence for a spectral turnover or break. Extrapolation of the X-ray power-law spectrum to higher energies reveals that a turnover in the 100 keV to 100 MeV range is required to accommodate the high-energy gamma-ray emission observed with Fermi-LAT, similar to the spectral energy distribution observed for the Crab pulsar.

description: In this paper, we present a detailed study of the problem of classical stability of U(1) gauged Q-balls. In particular, we show that the standard methods that are suitable for establishing the classical stability criterion for ordinary (nongauged) one-field and two-field Q-balls are not effective in the case of U(1) gauged Q-balls, although all the technical steps of calculations can be performed in the same way as those for ordinary Q-balls. We also present the results of numerical simulations in models with different scalar field potentials, explicitly demonstrating that, in general, the regions of stability of U(1) gauged Q-balls are not defined in the same way as in the case of ordinary Q-balls. Consequently, the classical stability criterion for ordinary Q-balls cannot be applied to U(1) gauged Q-balls in the general case.

description: In this paper we use Bayesian networks to determine and visualise the interactions among various Class III malocclusion maxillofacial features during growth and treatment. We start from a sample of 143 patients characterised through a series of a maximum of 21 different craniofacial features. We estimate a network model from these data and we test its consistency by verifying some commonly accepted hypotheses on the evolution of these disharmonies by means of Bayesian statistics. We show that untreated subjects develop different Class III craniofacial growth patterns as compared to patients submitted to orthodontic treatment with rapid maxillary expantion and facemask therapy. Among treated patients the CoA segment (the maxillary length) and the ANB angle (the antero-posterior relation of the maxilla to the mandible) seem to be the skeletal subspaces that receive the main effect of the treatment.

description: A one-dimensional (1D) $q$-state Potts model with $N$ sites, $m$-site interaction $K$ in a field $H$ is studied for arbitrary values of $m$. Exact results for the partition function and the two-point correlation function are obtained at $H=0$. The system in a field is shown to be self-dual. Using a change of Potts variables, it is mapped onto a standard 2D Potts model, with first-neighbour interactions $K$ and $H$, on a cylinder with helical boundary conditions (BC). The 2D system has a length $N/m$ and a transverse size $m$. Thus the Potts chain with multi-site interactions is expected to develop a 2D critical singularity along the self-duality line, $(e^{qK}-1)(e^{qH}-1)=q$, when $N/m\to\infty$ and $m\to\infty$.

title: Working through oil: skill, ethics, and masculinities in the Scottish oil and gas Industry
Creators: name: Watt, Connor
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2022

description: My thesis centres on the lives of oil and gas workers in North East Scotland, focussing on the specific ways of life which arise around this particular form of work. The research is based on 18 months of ethnographic fieldwork conducted with oil workers and their families in small coastal towns in Aberdeenshire and the Moray coast. My interlocutors are broadly split between an older generation who identify closely with forms of masculinity and work ethics which emerged alongside the initial development of the industry in the ‘early era’; and a younger generation of workers whose relationships to this form of labour have shifted in line with industry-wide changes and are more firmly rooted in the wider ethical livelihoods and kinship patterns made possible through work in the industry. The ethnographic material concentrates on material and temporal processes associated with resource production, in combination with intimate personal ethnographies of a number of key interlocutors from varied sections of the industry. A number of theoretical topics are developed in the thesis - the emergence of ethical attachments to work through processes of developing skills ‘in’ and ‘around’ labour; shifting gender ideologies and kinship arrangements which shape and are shaped by changes in the industry; differentiated understandings of agency in relation to windfall wealth and a dominant regional industry. During my fieldwork the industry was going through a period of intense downturn, with widespread redundancies and work becoming increasingly precarious. This moment of disruption spurred much discussion around the role of the industry in the region, the legacies of other forms of work, and the potential for alternative livelihoods in an area dominated by the oil industry. These issues take on increasing importance with discussions around the looming end of oil, and the possibilities of securing a just transition away from fossil fuel production.

description: Intermediate-scale quantum devices are becoming more reliable, and may soon be harnessed to solve useful computational tasks. At the same time, common classical methods used to verify their computational output become intractable due to a prohibitive scaling of required resources with system size. Inspired by recent experimental progress, here we describe and analyze efficient cross-platform verification protocols for quantum states and show how these can be used to verify computations. We focus on the pair-wise comparison between distant nodes of a quantum network, identify the most promising protocols and then discuss how they can be implemented in laboratory settings. As a proof of principle, we implement basic versions of these schemes on available quantum processors.

The Curie-like softening of $\left(C_{11}-C_{12}\right)/2$ between 1 and 5 K of the present Pr-37% system can be reproduced by a multipolar susceptibility calculation based on the non-Kramers $Γ_3$ doublet crystalline-electric-field ground state. Further, on cooling below 0.15 K, a temperature dependence proportional to $\sqrt{T}$ was observed in $\left(C_{11}-C_{12}\right)/2$. This behavior rather corresponds to the theoretical prediction of the quadrupolar Kondo "lattice" model, unlike that of the Pr-3.4% system, which shows a logarithmic temperature dependence based on the "single-site" quadrupolar Kondo theory. In addition, we discuss the possibility to form a vibronic state by the coupling between the low-energy phonons and the electric quadrupoles of the non-Kramers doublet in the Pr-37% system, since we found a low-energy ultrasonic dispersion in the temperature region between 0.15 and 1 K.

description: El presente artículo analiza cómo ante los desafíos de la Globalización y las estructuras hegemónicas de poder que gobiernan las relaciones norte-sur y es posible establecer alianzas epistémicas y prácticas entre los feminismos decoloniales y las teorías queer. Estas alianzas nos permiten articular marcos teóricos conectados, a partir de una pluralidad de visiones que respetan las diferencias y nos permiten elaborar críticas capaces de imaginar políticas no hegemónicas y emancipadoras. El texto analiza las principales tesis del feminismo decolonial para poder establecer puntos de conexión con otras teorías y dar respuestas a las necesidades del presente global.

description: Protein lysine acetylation is a critical post-translation modification (PTM) involved in a wide range of biological processes. To date, about 20,000 acetylation sites of homo sapiens were identified through mass spectrometry-based proteomic technology but more than 95% of them have unclear functional annotations due to the lack of existing prioritization strategy to assess the functional importance of the acetylation sites in large-scale. Hence, based on machine learning of 8 critical features surrounding lysine acetylation site, we established a lysine acetylation functional evaluating model (LAFEM) to high-throughput estimate the functional importance of given acetylation sites. Random-forest model and under-sampling dataset with the best performance were selected to construct LAFEM. Global analysis demonstrated that acetylation sites with high acetylation functional scores (AFSs) were commonly located in hub proteins and their molecular environment mainly had the features of larger solvent accessible surface area (SASA), stronger hydrogen-bonding-donating abilities, higher homology and disordered degree. Importantly, LAFEM performed well in validation dataset and acetylome and showed good complementarity with differentially expressed analysis. Cellular experiment confirmed that, in Nuclear Casein Kinase and Cyclin Dependent Kinase Substrate 1 (NUCKS1), acetyl-K35 with higher AFS was more important than acetyl-K9 with lower AFS in the proliferation of A549 cells. LAFEM provides a prioritization strategy to discover large-scale functional acetylation sites, which constitutes an unprecedented resource for better understanding of functional acetylome.

description: In this work, we study the production of Higgs boson pairs at next-to-next-to-leading order in QCD matched to parton showers, using the \textsc{Geneva} framework and working in the heavy-top-limit approximation. This includes the resummation of large logarithms of the zero-jettiness $\mathcal{T}_0$ up to the next-to-next-to-next-to-leading-log accuracy. This process features an extremely large momentum transfer, which makes its study particularly relevant for matching schemes such as that employed in \textsc{Geneva}, where the resummation of a variable different from that used in the ordering of the parton shower is used. To further study this effect, we extend the original shower interface designed for \textsc{Pythia8} to include other parton showers, such as \textsc{Dire} and \textsc{Sherpa}.

description: Gravity in $4d$ asymptotically flat spacetime constitutes the archetypal example of a gravitational system with leaky boundary conditions. Pursuing our analysis of [1], we argue that the holographic description of such a system requires the coupling of the dual theory living at null infinity to some external sources encoding the radiation reaching the conformal boundary and responsible for the non-conservation of the charges. In particular, we show that the sourced Ward identities of a conformal Carrollian field theory living at null infinity reproduce the BMS flux-balance laws. We also derive the general form of low-point correlation functions for conformal Carrollian field theories and exhibit a new branch of solutions, which is argued to be the relevant one for holographic purposes. We then relate our Carrollian approach to the celestial holography proposal by mapping the Carrollian Ward identities to those constraining celestial operators through a suitable integral transform.

description: Bell's theorem has fascinated physicists and philosophers since his 1964 paper, which was written in response to the 1935 paper of Einstein, Podolsky, and Rosen. Bell's theorem and its many extensions have led to the claim that quantum mechanics and by inference nature herself are nonlocal in the sense that a measurement on a system by an observer at one location has an immediate effect on a distant "entangled" system (one with which the original system has previously interacted). Einstein was repulsed by such "spooky action at a distance" and was led to question whether quantum mechanics could provide a complete description of physical reality. In this paper I argue that quantum mechanics does not require spooky action at a distance of any kind and yet it is entirely reasonable to question the assumption that quantum mechanics can provide a complete description of physical reality. The magic of entangled quantum states has little to do with entanglement and everything to do with superposition, a property of all quantum systems and a foundational tenet of quantum mechanics.

description: Die Eingliederung des Forschungszentrums caesar, Bonn, in die Max-Planck-Gesellschaft (MPG) würdigt der Wissenschaftsrat als einen folgerichtigen Schritt in der Entwicklung des Instituts. Dass caesar als assoziiertes Institut bereits der wissenschaftlichen Governance der MPG unterlag, trug maßgeblich zu einem reibungslosen strukturellen Übergang bei. Damit ist es gelungen für das Forschungszentrum caesar, das von der gleichnamigen Stiftung getragen wurde, eine verlässliche Zukunftsperspektive als Max-Planck-Institut für Neurobiologie des Verhaltens zu schaffen.
Die MPG hat ein gut etabliertes Forschungsinstitut mit einem erheblichen Stiftungsvermögen übernommen. Bis zum Aufbrauchen dieses Vermögens ist caesar in einer besonderen Finanzierungssituation, die es von anderen Max-Planck-Instituten unterscheidet. Ein maßgeblicher Erfolgsfaktor für die Vollintegration ist die Anwendung aller regulären Steuerungsmechanismen der MPG ohne Berücksichtigung der besonderen Finanzierungsstruktur des Instituts. Dies beinhaltet auch die vorausschauende Integration des Instituts in den Haushalt der MPG.

description: Este trabajo propone una lectura de Las aventuras de la China Iron en relación con el canon literario y el imaginario étnico en Argentina, con la lengua de un Estado que se constituyó monolingüe y con la hegemonía heteropatriarcal. Para este propósito utilizo aportes de los estudios culturales (Jameson) y de género (Haraway) así como antropológicos (Cadogan, Melià, Clastres), que evidencian cómo la novela articula cada apuesta desestabilizadora en el orden de especies, de clases y de géneros, así como en el orden étnico, cultural y lingüístico que sustentan el imaginario nacional.

description: In this paper, we consider the recently proposed hybrid metric-Palatini gravitational theory, which consists of adding to the Einstein-Hilbert Lagrangian an $f(\mathcal{R})$ term constructed à la Palatini. Using the respective dynamically equivalent scalar-tensor representation, we explore the cosmological evolution of a specific model, given by $f(\mathcal{R}) \propto \mathcal{R}^2$, and obtain constraints on the free parameters by using different sources of cosmological data. The viability of the model is analysed by combining the conditions imposed by the Supernovae Ia and Baryonic Acoustic Oscillations data and the results are compared with the local constraints.

description: Extreme events are ubiquitous in a wide range of dynamical systems, including turbulent fluid flows, nonlinear waves, large scale networks and biological systems. Here, we propose a variational framework for probing conditions that trigger intermittent extreme events in high-dimensional nonlinear dynamical systems. We seek the triggers as the probabilistically feasible solutions of an appropriately constrained optimization problem, where the function to be maximized is a system observable exhibiting intermittent extreme bursts. The constraints are imposed to ensure the physical admissibility of the optimal solutions, i.e., significant probability for their occurrence under the natural flow of the dynamical system. We apply the method to a body-forced incompressible Navier--Stokes equation, known as the Kolmogorov flow. We find that the intermittent bursts of the energy dissipation are independent of the external forcing and are instead caused by the spontaneous transfer of energy from large scales to the mean flow via nonlinear triad interactions. The global maximizer of the corresponding variational problem identifies the responsible triad, hence providing a precursor for the occurrence of extreme dissipation events. Specifically, monitoring the energy transfers within this triad, allows us to develop a data-driven short-term predictor for the intermittent bursts of energy dissipation. We assess the performance of this predictor through direct numerical simulations.
