description: In this paper, we study the tectonic stress around the South Caspian Basin (SCB), which includes the Kopeh Dagh, Alborz, Talesh, eastern Greater Caucasus mountain belts, the Apsheron sill, and the Balkhan-Ashkabad fault zone. We apply the stress inversion to focal mechanisms of 410 mainshocks that have occurred over the last 69 years. These mechanisms indicate that the surrounding fault zones of the SCB exhibit diverse types of faulting, ranging from thrust to strike-slip, normal, and their combinations. The results of the stress inversion align with the kinematics of the major fault zones bounding the SCB and emphasize the spatial heterogeneity of the stress field in this region. The region is predominantly under compression, but transpressive and strike-slip regimes are also present. This highlights the role of obliquely oriented basement faults with respect to the maximum horizontal compressive stress (SHmax) in accommodating deformation through convergent zones. The orientation of the SHmax is in the NE to NNE direction in the Kopeh Dagh, Alborz, Talesh, and Ashkabad-Balkhan fault zones, being rotated to NNE-N in the Greater Caucasus. The orientation of the SHmax relative to the convergence direction of the Arabian and Eurasian plates indicates that the Arabian-Eurasian oblique convergence-derived tectonic stress is the primary contributor to the total stress and deformation in this region.

Enfermedad laboral o común

description: Habitualmente, el ausentismo laboral es concebido por ser esa consecuencia negativa entre el tiempo que invierte el empleado que fue vinculado a una empresa y el tiempo que realmente utilizó para desarrollar sus funciones.

Para establecer estas estrategias inicialmente se desarrolló una caracterización integral del ausentismo laboral del sector arcillero que integra a la Empresa STN Temporal S.A.S. ubicada en el municipio El Zulia, Norte de Santander. Es importante tener en cuenta que este estudio abordó los factores que llevan a que se presente ese fenómeno teniendo una delimitación temporal compuesta por el período del primer semestre del 2022 al primer semestre del 2023.

Posteriormente, se determinó las causas que condujeron al ausentismo laboral del sector arcillero de la empresa STN Temporal S.A.S. para ello se tuvo en cuenta la percepción de quienes ocupan los cargos de dirección en esa organización y en sus diferentes unidades de trabajo.

Finalmente, la investigación estableció unas estrategias pedagógicas de mitigación del ausentismo laboral para que sea aplicada en un futuro cercano en el sector arcillero de la Empresa STN Temporal S.A.S., teniendo en cuenta las disposiciones y las exigencias del Sistema de Gestión de la Seguridad y Salud en el Trabajo SG-SST.

description: Topology-driven nonlinear light-matter effects open up new paradigms for both topological photonics and nonlinear optics. Here, we propose to achieve high-efficiency second-harmonic generation in a second-order photonic topological insulator. Such system hosts highly localized topological corner states with large quality factors for both fundamental and second harmonic waves, which could be matched perfectly in frequency by simply tuning the structural parameters. Through the nonlinear interaction of the doubly resonant topological corner states, unprecedented frequency conversion efficiency is predicted. In addition, the robustness of the nonlinear process against defects is also demonstrated. Our work opens up new avenues toward topologically protected nonlinear frequency conversion using high-order photonic topological modes.

description: A Uranus orbiter would be well positioned to detect the planet's free oscillation modes, whose frequencies can resolve questions about Uranus's weakly constrained interior. We calculate the spectra that may manifest in resonances with ring orbits or in Doppler imaging of Uranus's visible surface, using a wide range of interior models that satisfy the present constraints. Recent work has shown that Uranus's fundamental (f) and internal gravity (g) modes have appropriate frequencies to resonate with Uranus's narrow rings. We show that even a single $\ell=2$ f or g mode detected in ring imaging or occultations can constrain Uranus's core extent and density. Fully fluid models typically have $\ell=2-7$ f mode frequencies slightly too high to resonate among the narrow rings. If Uranus has a solid core that f modes cannot penetrate, their frequencies are reduced, rendering them more likely to be observed. A single $\ell\gtrsim7$ f mode detection would constrain Uranus's unknown rotation period. Meanwhile, the different technique of Doppler imaging seismology requires specialized instrumentation but could deliver many detections, with best sensitivity to acoustic (p) modes at mHz frequencies. Deviations from uniform frequency spacing can be used to locate density interfaces in Uranus's interior, such as a sharp core boundary. Shallower nonadiabaticity and condensation layers complicate this approach, but higher-order frequency differences can be analyzed to disentangle deep and near-surface effects. The detection of normal modes by a Uranus orbiter would help to discern among the degenerate solutions permitted by conventional measurements of the planet's static gravity field.

description: Second-order photonic topological insulators that host highly localized corner states resilient to defects, are opening new routes towards developing fascinating photonic devices. However, the existing works on second-order photonic topological insulators have mainly focused on either transverse magnetic or transverse electric modes. In this paper, we propose a dual-polarization topological photonic crystal structure for both transverse magnetic and transverse electric modes through topology optimization. Simple tight-binding lattice models are constructed to reveal the topological features of the optimized photonic crystal structure in a transparent way. The optimized dual-polarization second-order photonic topological insulator hosts four groups of corner states with different profiles and eigenfrequencies for both the transverse magnetic and transverse electric modes. Moreover, the robustness of theses corner states against defects is explicitly demonstrated. Our results offer opportunities for developing polarization-independent topological photonic devices.

description: Understanding of dicofol’s behavior in soil is crucial for more precise pest control and minimal environmental effect. Therefore, the goal of this study was to assess how the physicochemical characteristics of 10 selected soils effects the sorption and degradation of dicofol behavior. The behavior of dicofol, including its adsorption and desorption properties as well as its rates of hydrolysis and photolysis degradation, was thoroughly examined via definitive studies. Standard batch equilibration mode for sorption revealed that it was dependent on the physical and chemical properties of the soil. Exothermic and spontaneous adsorption processes, which were characterized by a negative Gibbs free energy value, were convincingly proven by thermodynamic study. The current investigation’s ΔG estimations varied from −18.6 kjmol−1 for soil-6 to −24.25 kjmol−1 for soil-9. The soil-7 with a notable organic matter content (1.81%) showed the maximum adsorption, and subsequently producing a C-type isotherm that was analyzed using a linear and Freundlich model. An analytical process using UV-VIS spectrophotometry to determine the fate of dicofol in soil matrices. Hydrolysis and photolysis studies yielded minimum half-lives of 13.4 and 1.32 days, respectively. It has been demonstrated that dicofol molecules interact strongly with soils, principally via physio-sorption mechanisms. In contrast to its strong soil affinity and permanence, dicofol exhibits a counterintuitive behavior that makes it vulnerable to sunlight-induced deterioration. Future studies will concentrate on enhancing these pathways to assist sustainable pesticide management strategies and creative pollution mitigation techniques.

description: One of the most fundamental questions in the field of relativistic heavy ion physics is how to reach and explore densities which are needed to cross the chiral and/or the deconfinement phase transition. In this analysis we investigate the information we can gather by analyzing baryonic and mesonic resonances on the hot and dense phase in such nuclear reactions. The decay products of these resonances carry information on the resonances properties at the space time point of their decay. We especially investigate the percentage of reconstructable resonances as a function of density for heavy ion collisions in the energy range between $E_{lab}$ = 30 AGeV and $\sqrt{s}$ = 200 AGeV, the energy domain between the future FAIR facility and the present RHIC collider.

description: The increasing precision of Cosmic Microwave Background (CMB) observations has unveiled significant tensions between different datasets, notably between Planck and the Atacama Cosmology Telescope (ACT), as well as with the late-Universe measurements of the Hubble constant. In this work, we explore a variety of $Λ$CDM extensions to assess their ability to reconcile these discrepancies. The statistical preference for these extensions remains moderate, and imposing $n_s=1$ often worsens model performance. Our findings highlight the limitations of incremental modifications to $Λ$CDM and suggest that either more complex new physics or, more likely, improved systematic understanding in the CMB sector may be required to fully address the observed tensions. While CMB experiments are often considered the gold standard of precision cosmology, our results reinforce that these measurements are not immune to systematic uncertainties, which may be underestimated in current analyses.

Effect of maturity and variety on the textural quality of green snap beans
Creators: name: Martens, Victor Jake
Publisher: name: University of British Columbia
Year: 2011

description: Rheological measurements on intact fresh snap beans (Phaseolus vulgaris v.) and purees made from raw beans were used to assess the effect of variety and sieve size on the textural characteristics of green snap beans. Seed length, percentage dry matter and physical fiber measurements were used as textural quality indicators. Four varieties of green snap beans (Tendercrop, Rainier, Harvester and BBL 290) were tested in 1971 and 1972. Each variety was harvested five times in each year. Adverse environmental conditions in 1971 caused bean textural quality to be higher in 1972 than in 1971. The four varieties tested showed significant differences with Rainier exhibiting the best textural quality while Harvester generally showed the poorest quality. Tests involving the resistance to shearing of intact bean pods were carried out using the Ottawa Texture Measuring System and the Food Technology Corporation's Texture Test System (formerly the Kramer shear press). Viscosity tests were performed on purees composed of macerated raw green bean tissue and water. Results were obtained from spread test using a simplified Adams-type consistometer and from rotating coaxial cylinder tests using a Brookfield RVT Synchro-Lectric Viscometer fitted with a small sample adapter. The Brookfield data were then fitted to the power-law equation. Rheological parameters showed highly significant interrelationships in most instances. Viscous properties of purees (spread, m, n and yield stress) were highly correlated with percentage dry matter of the beans. Peak force readings of the Kramer shear press and the Ottawa Texture Measuring System were significantly correlated with all textural quality and viscometric parameters.

description: Detailed chemical analyses of M dwarfs are scarce but necessary to constrain the formation environment and internal structure of planets being found around them. We present elemental abundances of 13 M dwarfs (2900 < Teff < 3500 K) observed in the Subaru/IRD planet search project. They are mid-to-late M dwarfs whose abundance of individual elements has not been well studied. We use the high-resolution (~70,000) near-infrared (970-1750 nm) spectra to measure the abundances of Na, Mg, Si, K, Ca, Ti, V, Cr, Mn, Fe, and Sr by the line-by-line analysis based on model atmospheres, with typical errors ranging from 0.2 dex for [Fe/H] to 0.3-0.4 dex for other [X/H]. We measure radial velocities from the spectra and combine them with Gaia astrometry to calculate the Galactocentric space velocities UVW. The resulting [Fe/H] values agree with previous estimates based on medium-resolution K-band spectroscopy, showing a wide distribution of metallicity (-0.6 < [Fe/H] < +0.4). The abundance ratios of individual elements [X/Fe] are generally aligned with the solar values in all targets. While the [X/Fe] distributions are comparable to those of nearby FGK stars, most of which belong to the thin disk population, the most metal-poor object, GJ 699, could be a thick disk star. The UVW velocities also support this. The results raise the prospect that near-infrared spectra of M dwarfs obtained in the planet search projects can be used to grasp the trend of elemental abundances and Galactic stellar population of nearby M dwarfs.

description: The black hole X-ray transient XTE J1550-564 has undergone a strong outburst in 1998 and two relativistic X-ray jets have been detected years later with the $\it Chandra$ X-ray observatory; the eastern jet was found previously to have decelerated after its first detection. Here we report a full analysis of the evolution of the western jet; significant deceleration is also detected in the western side. Our analysis indicates that there is a cavity outside the central source and the jets first traveled with constant velocity and then were slowed down by the interactions between the jets and the interstellar medium (ISM). The best fitted radius of the cavity is $\sim$0.31 pc on the eastern side and $\sim$0.44 pc on the western side, and the densities also show asymmetry, of $\sim$0.034 cm$^{-3}$ on the east to $\sim$0.12 cm$^{-3}$ on the west. The best fitted magnetic fields on both sides are $\sim$0.5 mG. Similar analysis is also applied to another microquasar system, H 1743-322, and a large scale low density region is also found. Based on these results and the comparison with other microquasar systems, we suggest a generic scenario for microquasar jets, classifying the observed jets into three main categories, with different jet morphologies (and sizes) corresponding to different scales of vacuous environments surrounding them. We also suggest that either continuous jets or accretion disk winds, or both may be responsible for creating these cavities. Therefore X-ray jets from microquasars provide us with a promising method of probing the environment of accreting black holes.

description: The symmetry of the whole experimental setups, including specific sample environments and measurables, can be compared with that of specimens for observable physical phenomena. We, first, focus on one-dimensional (1D) experimental setups, independent from any spatial rotation around one direction, and show that eight kinds of 1D objects (four; vectorlike, the other four; director-like), defined in terms of symmetry, and their dot and cross products are an effective way for the symmetry consideration. The dot products form a Z2xZ2xZ2 group with Abelian additive operation, and the cross products form a Z2xZ2 group with Abelian additive operation or Q8, a non-abelian group of order eight, depending on their signs. Those 1D objects are associated with characteristic physical phenomena. When a 3D specimen has Symmetry Operational Similarity (SOS) with (identical or lower, but not higher, symmetries than) an 1D object with a particular phenomenon, the 3D specimen can exhibit the phenomenon. This SOS approach can be a transformative and unconventional avenue for symmetry-guided materials designs and discoveries.

It is shown that the only correction to the action is a change in the potential. All characteristics of the motion (frequencies of oscillations, times of rolling, a phase portrait etc.) can be computed by means of a classical mechanics for the corrected potential. In particular, a tunneling in the system is absent.

description: A long and intense debate in philosophy is concerned with the question whether there can be haecceistic differences between possible worlds, that is, nonqualitative differences that only arise from different de re representations. According to haecceitism, it can give rise to a different situation if the positions of two qualitatively identical particles are exchanged, while according to anti-haecceitism, this is not the case. It has been suggested that classical statistical mechanics might provide evidence for one of these positions. However, most philosophers of physics argue that it does not. In this article, we show that order-preserving dynamics, a novel method from statistical mechanics developed for the description of nonergodic systems, changes this situation: It is intrinsically haecceistic and makes different experimental predictions than non-haecceistic alternatives. Thereby, it provides an empirical argument for the existence of modality de re.

description: It is known that there are thermodynamic states for which the Gaussian-core (GC) fluid displays anomalous properties such as expansion upon isobaric cooling (density anomaly) and increased single-particle mobility upon isothermal compression (self-diffusivity anomaly). We investigate how temperature and density affect its short-range translational structural order, as characterized by the two-body excess entropy. We find that there is a wide range of conditions for which the short-range translational order of the GC fluid decreases upon isothermal compression (structural order anomaly). The origin of the structural anomaly is qualitatively similar to that of other anomalous fluids and is connected to how compression affects static correlations at different length scales. We find that the self-diffusivity of the GC fluid obeys a scaling relationship with the two-body excess entropy that is very similar to the one observed for a variety of simple liquids. One consequence of this relationship is that the state points for which structural, self-diffusivity, and density anomalies of the Gaussian-core fluid occur appear as cascading regions on the temperature-density plane, a phenomenon observed earlier for models of waterlike fluids. There are, however, key differences between the anomalies of GC and waterlike fluids, and we discuss how those can be qualitatively understood by considering the respective interparticle potentials of these models. Finally, we note that the self-diffusivity of the Gaussian-core fluid obeys different scaling laws depending on whether the two-body or total excess entropy is considered. This finding, which deserves more comprehensive future study, appears to underscore the significance of higher-body correlations for the behavior of fluids with bounded interactions.

description: A parameterization strategy for molecular models on the basis of force fields is proposed, which allows a rapid development of models for small molecules by using results from quantum mechanical (QM) ab initio calculations and thermodynamic data. The geometry of the molecular models is specified according to the atom positions determined by QM energy minimization. The electrostatic interactions are modeled by reducing the electron density distribution to point dipoles and point quadrupoles located in the center of mass of the molecules. Dispersive and repulsive interactions are described by Lennard-Jones sites, for which the parameters are iteratively optimized to experimental vapor-liquid equilibrium (VLE) data, i.e. vapor pressure, saturated liquid density, and enthalpy of vaporization of the considered substance. The proposed modeling strategy was applied to a sample set of ten molecules from different substance classes. New molecular models are presented for iso-butane, cyclohexane, formaldehyde, dimethyl ether, sulfur dioxide, dimethyl sulfide, thiophene, hydrogen cyanide, acetonitrile, and nitromethane. Most of the models are able to describe the experimental VLE data with deviations of a few percent.

description: This presentation was given at the International Data Week 2023 in Salzburg, AT (2023, October 23-26).In this contribution we presented an integrated approach to monitoring and assessing the state of open and FAIR data in a federated research organization. The project is part of a multi-method approach of the Helmholtz Metadata Collaboration (HMC).

The Helmholtz Metadata Collaboration (HMC) is part of the Helmholtz Information & Data Science Incubator. It brings to life the digitalization strategy of the Helmholtz Association, which is Germany’s largest research organization, spanning a wide range of research disciplines in 18 research centers.

HMC fosters FAIR data practices across the Helmholtz Association and supports the qualitative enrichment of research data with metadata. To continuously monitor and communicate the status quo and progress over time, several key questions needed to be resolved:

1. Where is research data deposited?2. How can we identify gaps towards a FAIR data space across the organization?3. How can we use this information to engage communities and infrastructure?

To address these questions HMC has developed and combined complementary, data-driven approaches - ranging from surveys and qualitative interviews, to data harvesting and the HMC dashboard on open and FAIR data in Helmholtz.

The dashboard provides interactive statistics on the state of data published alongside journal publications. The data analyzed in the dashboard is obtained from a pipeline that starts with harvesting literature metadata from the libraries of associated research centers, and continues by using SCHOLIX links to identify data publications linked to that literature. We have adopted the F-UJI framework as a first approach to automated FAIR assessment of the data found.

The combination of approaches provides insight into which repositories are used by researchers to make research data publicly accessible, it enables analyses on the target groups of the repositories identified, and renders information on systematic gaps of this data with respect to the FAIR data guidelines. Interested members of the research communities can evaluate their FAIR data practices and find useful information on how they can improve them.

In selected examples we illustrate how the information provided in the dashboard could be used to identify systematic gaps with respect to FAIR data, and to effectively counsel data infrastructure towards improving FAIR data across the organization. 

The dashboard is available on https://fairdashboard.helmholtz-metadaten.de/ and all source code is open and ready for reuse by research organizations, universities, and the general public.

description: We incorporate strong negation in the theory of computable functionals TCF, a common extension of Plotkin's PCF and Gödel's system $\mathbf{T}$, by defining simultaneously strong negation $A^{\mathbf{N}}$ of a formula $A$ and strong negation $P^{\mathbf{N}}$ of a predicate $P$ in TCF. As a special case of the latter, we get strong negation of an inductive and a coinductive predicate of TCF. We prove appropriate versions of the Ex falso quodlibet and of double negation elimination for strong negation in TCF. We introduce the so-called tight formulas of TCF i.e., formulas implied by the weak negation of their strong negation, and the relative tight formulas. We present various case-studies and examples, which reveal the naturality of our definition of strong negation in TCF and justify the use of TCF as a formal system for a large part of Bishop-style constructive mathematics.

description: Let n be an even positive integer and F be the field \GF(2). A word in F^n is called balanced if its Hamming weight is n/2. A subset C \subseteq F^n$ is called a balancing set if for every word y \in F^n there is a word x \in C such that y + x is balanced. It is shown that most linear subspaces of F^n of dimension slightly larger than 3/2\log_2(n) are balancing sets. A generalization of this result to linear subspaces that are "almost balancing" is also presented. On the other hand, it is shown that the problem of deciding whether a given set of vectors in F^n spans a balancing set, is NP-hard. An application of linear balancing sets is presented for designing efficient error-correcting coding schemes in which the codewords are balanced.

description: This study aims to assess ecological risks from heavy metal atmospheric deposition in the Indus River at Kotri Barrage, Sindh, Pakistan. Monitoring occurred at four locations, yielding 40 air samples analyzed for heavy metals via Triple Quadrupole Inductively Coupled Plasma Mass Spectrometry (TQ-ICP-MS). Pollution indicators, including Contaminant Factor (CF), Degree of Contamination (CD), Geo-accumulation Index (Igeo), Enrichment Factor (EF), Pollution Load Index (PLI), Potential Ecological Risk Index (PERI), and Nemerow Integrated Pollution Index (NIPI), quantified contaminant levels. Air monitoring revealed PM2.5 concentrations exceeding regulatory guidelines at all four sites. Heavy metal mean concentrations ranked as follows: Fe > Cr > Pb > Mn > As > Cu > Ni > Cd > Mo > Co, and deposition fluxes followed this order: Fe > Pb > Cr > Mn > As > Cu > Ni > Cd > Mo > Co. Pollution indices indicated moderate to extreme pollution for Fe, Cr, Cd at all sites, and Pb at site D. Emissions from a nearby coal-fired power plant and vehicular sources were identified as primary contributors to high heavy metal deposition. The Ecological Risk Index ranged from 150 to 600, signifying substantial ecological risk linked to Cd. These findings offer crucial insights for governmental agencies and policymakers to address pollution issues arising from heavy metal atmospheric deposition in the Indus River near Kotri Barrage.
title: Exploring the Roles of Help-Seeking Behaviours, Therapeutic Alliance, and Single Session Therapy on UK University Students’ Mental Health
Creators: name: Williams, Siobhan
Publisher: name: University of Liverpool Repository
Year: 2024

description: Chapter one includes the systematic review exploring university students’ perceived barriers and facilitators to help-seeking for mental health support. By synthesising existing literature, this review aimed to shed light on the factors that influence students' decision-making processes when it comes to seeking professional assistance for their mental health concerns. The increasing prevalence of mental health concerns and reports of limited help-seeking by students underscore the importance of understanding the barriers and facilitators among UK university students. By identifying the factors that hinder or encourage students to seek mental health support, institutions can develop targeted strategies to improve access, reduce stigma, and provide more effective assistance to those in need.
Chapter two incorporates a mixed methods empirical study consisting of two key areas of consideration: 1. A quantitative study on university students’ perceived changes in mental health concerns following SST; and 2. A qualitative study using interpretative phenomenological analysis (IPA) to explore therapists’ experiences of delivering SST within a university setting. By considering the first-hand experiences and perspectives of therapists, this qualitative investigation seeks to provide insights into the challenges, successes, and unique considerations associated with delivering this intervention in a university context.
Together, this thesis seeks to contribute to a deeper understanding of mental health support within UK universities, highlighting both the student perspective and the experiences of therapists. The findings from this thesis have the potential to inform and enhance mental health services in higher education, with the ultimate goal of improving student well-being and reducing the negative consequences associated with untreated mental health issues.

description: Metal(loid) pollutants in road dust (road-deposited sediment) show obvious seasonal characteristics under the influence of sources. However, the short-term (days to weeks) variations of metal contamination in road dust in different functional areas with antecedent dry days (ADDs) and their relationships with the source factors were poorly understood, which reduced the comparability of researches and effectiveness of pollution remediation. Herein, temporal characteristics of As, Ba, Ca, Cd, Cr, Cu, Pb and Zn contamination in road dust were studied in two distinct functional areas in Nanjing, i.e. an urban park (Xuanwu, XW) and a stop light-controlled traffic intersection (Baima, BM), following a continuous 23-day sampling between two rainfall events. Mean concentrations of each metal at BM and XW were 1.6–29.5 and 1.3–10.8 times higher than those in the background soil, respectively. The enrichment factor (EF) was used to compensate for grain-size effect. EFs of metals were between 1.3 and 50.3, showing minor to extremely high contamination and different temporal trends. Combined with the EFs and positive matrix factorization (PMF) results, dry atmospheric deposition of industrial and construction sources was the main cause for comparable contamination levels of As, Ca, Cd and Zn between BM and XW and those stable temporal trends. Due to the traffic contribution, contamination levels of Cu, Ba, Pb and Cr at BM were higher (p < .05) than at XW. Different from the stable contamination levels at XW, contamination levels of Cu, Ba, Pb and Cr decreased at BM with the ADDs due to the dilution of traffic particles by less metal enriched atmospheric deposition. These results shed light on the quite different variations of metal contamination in road dust from different functional areas with ADDs under the influence sources, and have instructive significance on road dust sampling, metal contamination remediation and comparison between studies.

description: The imminent launch of space telescopes designed to probe the atmospheres of exoplanets has prompted new efforts to prioritise the thousands of transiting planet candidates for follow-up characterisation. We report the detection and confirmation of TOI-1842b, a warm Saturn identified by TESS and confirmed with ground-based observations from Minerva-Australis, NRES, and the Las Cumbres Observatory Global Telescope. This planet has a radius of $1.04^{+0.06}_{-0.05}\,R_{Jup}$, a mass of $0.214^{+0.040}_{-0.038}\,M_{Jup}$, an orbital period of $9.5739^{+0.0002}_{-0.0001}$ days, and an extremely low density ($ρ$=0.252$\pm$0.091 g cm$^{-3}$). TOI-1842b has among the best known combinations of large atmospheric scale height (893 km) and host-star brightness ($J=8.747$ mag), making it an attractive target for atmospheric characterisation. As the host star is beginning to evolve off the main sequence, TOI-1842b presents an excellent opportunity to test models of gas giant re-inflation. The primary transit duration of only 4.3 hours also makes TOI-1842b an easily-schedulable target for further ground-based atmospheric characterisation.

Lovelock gravity and Weyl's tube formula

description: In four space-time dimensions, there are good theoretical reasons for believing that General Relativity is the correct geometrical theory of gravity, at least at the classical level. If one admits the possibility of extra space-time dimensions, what would we expect classical gravity to be like? It is often stated that the most natural generalisation is Lovelock's theory, which shares many physical properties with GR. But there are also key differences and problems. A potentially serious problem is the breakdown of determinism, which can occur when the matrix of coefficients of second time derivatives of the metric degenerates. This can be avoided by imposing inequalities on the curvature. Here it is argued that such inequalities occur naturally if the Lovelock action is obtained from Weyl's formulae for the volume and surface area of a tube. Part of the purpose of this article is to give a treatment of the Weyl tube formula in terminology familiar to relativists and to give an appropriate (straightforward) generalisation to a tube embedded in Minkowski space.
