Modeling gravitational few-body problems with tsunami and okinami
Authors: Trani Alessandro A. , Spera Mario 
Published: January 2023

AbstractIn recent years, an increasing amount of attention is being paid to the gravitational few-body problem and its applications to astrophysical scenarios. Among the main reasons for this renewed interest there is large number of newly discovered exoplanets and the detection of gravitational waves. Here, we present two numerical codes to model three- and few-body systems, called tsunami and okinami. The tsunami code is a direct few-body code with algorithmic regularization, tidal forces and post-Newtonian corrections. okinami is a secular, double-averaged code for stable hierarchical triples. We describe the main methods implemented in our codes, and review our recent results and applications to gravitational-wave astronomy, planetary science and statistical escape theories.
Detecting cosmic filamentary network with stochastic Bisous model
Authors: Mihkel Muru Moorits 
Published: January 2023

AbstractThe Bisous model is a tool that uses stochastic methods to detect the network of galactic filaments. This model is explicitly developed to detect the structure from observational data, using only galaxy positions as input. This paper shows that the Bisous model gives reliable results and including photometric data improves the resulting filamentary network. We used MultiDark-Galaxies catalogue to create a mock with photometric redshifts and samples with different galaxy number densities. We found that the filaments detected with the Bisous model are reliable; 85% of the detected filaments are unchanged compared to results with more complete input data. Adding photometric data improves the fraction of galaxies in filaments. Using the confusion matrix technique, we found the false discovery rate to always be below 5% when using photometric data.

AbstractThe earthquake sequence, with a maximum earthquake magnitude of MW 3.8, that occurred during January–February 2022 at the northern Dead Sea fault, is shown to be induced by extensive groundwater abstraction in Wadi Al‐Arab basin. Wadi Al‐Arab basin, which is bordered in the west by the Dead Sea fault, has been overexploited by extensive groundwater abstraction causing significant drawdowns. Relative earthquake relocation indicates an elongated S‐N sequence subparallel to the Dead Sea fault. We simulate the three‐dimensional hydraulic head changes in the past 40 years at Wadi al Arab basin. Results show that the drawdowns at the Dead Sea fault wells reached a value greater than 180 m. We use these results to further model the poroelastic effects of the drawdown on the stability of the Dead Sea fault using a typical fault architecture including fault core surrounded by damage zone. Upward groundwater drainage through the permeable damage zone leads to compaction and strengthening. Failure on the Dead Sea fault is expected to occur on the impermeable fault core or at the protholith where weakening is expected. Groundwater abstraction in Wadi Al‐Arab basin cause changes of a few MPa in the Coulmb Failure Stress (ΔCFS) and trigger seismicity in these sections. This is the second location along the Dead Sea fault where groundwater abstraction was shown to recently induce earthquakes. With growing demand for water and long lasting droughts in the Middle East, seismicity induced by groundwater abstraction might reoccur in the near future.

Published: January 2023

AbstractBased on high‐resolution, cross‐frontal towed measurements, this study investigates temperature‐salinity (T‐S) compensation and its scale dependence in the Taiwan Strait. In winter and spring when the northeasterly monsoon is prevailing, colder and fresher waters flow southward along the coast of the Chinese mainland, which encounter the northward‐flowing, warmer and saltier waters in the Taiwan Strait. Two slanted density fronts are generated across the interfacing zone forming a cone‐shaped isopycnal distribution in the cross‐frontal direction. Analyses based on the density ratio and Turner angle suggest the expected S‐dominated and T‐dominated types of density variations at the western and eastern density fronts, respectively. Exact T‐S compensation is observed within the interfacing zone. Analysis of the scale dependence indicates that temperature and salinity get more (less) compensated from O(10 km) to O(1 km) scale in the S‐dominated (T‐dominated) frontal zone. Although contrasting density compensating features are observed on the two flanks of the transition zone, they can both be interpreted by the restratification‐cooling mechanism. Specifically, the overturning cells due to submesoscale instabilities in the upper mixed layer slump isopycnals in the frontal zone, inducing shoaling of the mixed layer at both ends of the sampled sections. Surface cooling results in larger temperature drops in the shallower mixed layers, and thus increases (decreases) the degree of T‐S compensation in the S‐dominated (T‐dominated) frontal zone at the scale for submesoscale instabilities to develop.

Published: January 2023

AbstractThe El Niño–Southern Oscillation (ENSO) is the dominant interannual variability affecting global weather and climate. However, limited observational records hinder our understanding of the evolution of natural ENSO variability and its driving mechanisms. In this study, ENSO variations from 665 to 749 CE (Common Era) were investigated using monthly sea surface temperature (SST) records of the northern South China Sea derived from coral strontium to calcium ratios of sub‐fossil Porites obtained at the Xisha Islands. The results suggested the existence of cold conditions in this period relative to the twentieth century. No change in SST seasonality for the CE was found that is in agreement with the orbitally controlled insolation seasonality at that time. ENSO variability during 665–749 CE was enhanced by 39% than that during 1980–2014 CE and exhibited fluctuations. A persistent dampened ENSO variability with frequent El Niño events from 665 to 700 CE was followed by a rapid increase in variability to a level double that of the present. The frequency of La Niña events increased during this time. The abrupt transformation of ENSO activity at 700 CE was attributed to the increased natural radiative forcing induced by intense solar irradiance and weak volcanism. This paper demonstrates that ENSO variability can be influenced by external forcings, such as changes in solar and volcanic activity, and not only by the internal dynamics of the climate system.

AbstractAcute liver failure (ALF) is a life-threatening disease that occurs secondary to drug toxicity, infection or a devastating immune response. Orthotopic liver transplantation is an effective treatment but limited by the shortage of donor organs, the requirement for life-long immune suppression and surgical challenges. Stem cell transplantation is a promising alternative therapy for fulminant liver failure owing to the immunomodulatory abilities of stem cells. Here, we report that when transplanted into the liver, human endoderm stem cells (hEnSCs) that are germ layer-specific and nontumorigenic cells derived from pluripotent stem cells are able to effectively ameliorate hepatic injury in multiple rodent and swine drug-induced ALF models. We demonstrate that hEnSCs tune the local immune microenvironment by skewing macrophages/Kupffer cells towards an anti-inflammatory state and by reducing the infiltrating monocytes/macrophages and inflammatory T helper cells. Single-cell transcriptomic analyses of infiltrating and resident monocytes/macrophages isolated from animal livers revealed dramatic changes, including changes in gene expression that correlated with the change of activation states, and dynamic population heterogeneity among these cells after hEnSC transplantation. We further demonstrate that hEnSCs modulate the activation state of macrophages/Kupffer cells via cystatin SN (CST1)-mediated inhibition of interferon signaling and therefore highlight CST1 as a candidate therapeutic agent for diseases that involve over-activation of interferons. We propose that hEnSC transplantation represents a novel and powerful cell therapeutic treatment for ALF.

AbstractThere is limited research exploring the knowledge and experiences of genetic healthcare from the perspective of people with intellectual disability. This study, conducted in New South Wales (Australia), addresses this gap. Eighteen adults with intellectual disability and eight support people were interviewed in this inclusive research study. The transcribed interviews were analysed using inductive content analysis. The findings were discussed in a focus group with ten adults with intellectual disability and in three multi-stakeholder advisory workshops, contributing to the validity and trustworthiness of the findings. Five main themes emerged: (i) access to genetic healthcare services is inequitable, with several barriers to the informed consent process; (ii) the experiences and opinions of people with intellectual disability are variable, including frustration, exclusion and fear; (iii) genetic counselling and diagnoses can be profoundly impactful, but translating a genetic diagnosis into tailored healthcare, appropriate support, peer connections and reproductive planning faces barriers; (iv) people with intellectual disability have a high incidence of exposure to trauma and some reported that their genetic healthcare experiences were associated with further trauma; (v) recommendations for a more respectful and inclusive model of genetic healthcare. Co-designed point-of-care educational and consent resources, accompanied by tailored professional education for healthcare providers, are required to improve the equity and appropriateness of genetic healthcare for people with intellectual disability.

AbstractThermal energy management in metal-organic frameworks (MOFs) is an important, yet often neglected, challenge for many adsorption-based applications such as gas storage and separations. Despite its importance, there is insufficient understanding of the structure-property relationships governing thermal transport in MOFs. To provide a data-driven perspective into these relationships, here we perform large-scale computational screening of thermal conductivity k in MOFs, leveraging classical molecular dynamics simulations and 10,194 hypothetical MOFs created using the ToBaCCo 3.0 code. We found that high thermal conductivity in MOFs is favored by high densities (> 1.0 g cm−3), small pores (< 10 Å), and four-connected metal nodes. We also found that 36 MOFs exhibit ultra-low thermal conductivity (< 0.02 W m−1 K−1), which is primarily due to having extremely large pores (~65 Å). Furthermore, we discovered six hypothetical MOFs with very high thermal conductivity (> 10 W m−1 K−1), the structures of which we describe in additional detail.
Natural and enriched Cr target development for production of Manganese-52

Published: January 2023

Abstract52Mn is a promising PET radiometal with a half-life of 5.6 days and an average positron energy of 242 keV. Typically, chromium of natural isotope abundance is used as a target material to produce this isotope through the nat/52Cr(p,n)52Mn reaction. While natural Cr is a suitable target material, higher purity 52Mn could be produced by transitioning to enriched 52Cr targets to prevent the co-production of long-lived 54Mn (t1/2 = 312 day). Unfortunately, 52Cr targets are not cost-effective without recycling processes in place, therefore, this work aims to explore routes to prepare Cr targets that could be recycled. Natural Cr foils, metal powder pellets, enriched chromium-52 oxide and Cr(III) electroplated targets were investigated in this work. Each of these cyclotron targets were irradiated, and the produced 52Mn was purified, when possible, using a semi-automated system. An improved purification by solid-phase anion exchange from ethanol-HCl mixtures resulted in recoveries of 94.5 ± 2.2% of 52Mn. The most promising target configuration to produce a recyclable target was electroplated Cr(III). This work presents several pathways to optimize enriched Cr targets for the production of high purity 52Mn.

AbstractPost-vaccination cytokine levels from 256 young adults who subsequently suffered breakthrough influenza infections were compared with matched controls. Modulation within the immune system is important for eliciting a protective response, and the optimal response differs according to vaccine formulation and delivery. For both inactivated influenza vaccine (IIV) and live attenuated influenza vaccines (LAIV) lower levels of IL-8 were observed in post-vaccination sera. Post-vaccination antibody levels were higher and IFN-γ levels were lower in IIV sera compared to LAIV sera. Subjects who suffered breakthrough infections after IIV vaccination had higher levels of sCD25 compared to the control group. There were differences in LAIV post-vaccination interleukin levels for subjects who subsequently suffered breakthrough infections, but these differences were masked in subjects who received concomitant vaccines. Wide variances, sex-based differences and confounders such as concomitant vaccines thwart the establishment of specific cytokine responses as a correlate of protection, but our results provide real world evidence that the status of the immune system following vaccination is important for successful vaccination and subsequent protection against disease.

Context. Gaps in circumstellar disks can signal the existence of planetary perturbers, making such systems preferred targets for direct imaging observations of exoplanets.
Aims. Being one of the brightest and closest stars to the Sun, the photometric standard star Vega hosts a two-belt debris disk structure. Together with the fact that its planetary system is being viewed nearly face-on, Vega has been one of the prime targets for planet imaging efforts.
Methods. Using the vector vortex coronagraph on Keck/NIRC2 in the Ms band at 4.67 μm, we report the planet detection limits from 1 au to 22 au for Vega with an on-target time of 1.8 h.
Results. We reach a 3 MJupiter limit outward of 12 au, which is nearly an order of magnitude deeper than for other existing studies. Combining our observations with existing radial velocity studies, we can confidently rule out the existence of companions more than ~8 MJupiter from 22 au down to 0.1 au for Vega. Interior and exterior to ~4 au, this combined approach reaches planet detection limits down to ~2–3 MJupiter using radial velocity and direct imaging, respectively.
Conclusions. By reaching multi-Jupiter mass detection limits, our results are expected to be complemented by the planet imaging of Vega in the upcoming observations using the James Webb Space Telescope to obtain a more holistic understanding of the planetary system configuration around Vega.
Le recyclage du verre au temps des Romains, des Francs et des Byzantins
Authors: Pactat Inès 
Published: January 2023

Le recyclage du verre ne date pas de 1974, année où la première collecte en France de verres d’emballage est organisée en Haute-Marne. Si cette initiative est désormais intégrée à notre quotidien, elle n’est néanmoins qu’un jalon récent de l’histoire de cette pratique.
À partir de plusieurs exemples de cargaisons antiques et byzantines chargées de verre brisé, de récits de vols de fenêtres et de vestiges archéologiques d’ateliers, nous proposons d’en retracer le cours, de l’Antiquité romaine au Moyen Âge.
La physique et la chimie permettent désormais de reconnaître ces activités de recyclage à partir d’analyses de la composition élémentaire du verre, nous faisant cheminer à la croisée des sciences humaines et des sciences dures.
Les verres, quel désordre ?
Authors: Cormier Laurent , Neuville Daniel R. 
Published: January 2023

L’absence d’ordre à longue distance, par opposition à l’état cristallin, et le phénomène de la transition vitreuse sont les principaux critères qui distinguent le verre des autres états de la matière.
Dans cet article, nous revenons sur les notions d’ordre et de désordre, de périodicité, et sur les différentes échelles d’organisation, en comparant les structures les plus ordonnées (les cristaux) avec celles des matériaux amorphes. Nous faisons un état des lieux sur la compréhension actuelle de la structure des verres, en montrant les avancées récentes issues de techniques expérimentales, révélant que cette structure est plus complexe que la vision traditionnelle d’un matériau désordonné homogène.
Opportunity beliefs in internationalization: A microhistorical approach
Authors: Leppäaho Tanja , Mainela Tuija , Paavilainen-Mäntymäki Eriikka 
Published: January 2023

AbstractWe propose the concept of opportunity belief as a means of understanding individuals as the interpreters of their contexts over the internationalization process of a firm. To illustrate the concept, we conducted a microhistorical analysis on one of the largest forest industry MNEs with an internationalization history of more than 150 years. Historical archival data and rich secondary material provided access to the reasonings of individuals over the firm’s internationalization. This allowed depiction of different types of opportunity beliefs as the drivers of internationalization actions within particular historical contexts. We portray opportunity belief as a complementary lens to current internationalization models focusing primarily on firm-level development.
Influence of a rural interprofessional education placement on the rural health workforce: working in primary care, rural settings, and with Māori

Introduction Pre-registration interprofessional rural immersion programmes provide students with first-hand insight into challenges faced in rural clinical practice and can influence future practice intentions. The impact of short rural and hauora Māori interdisciplinary placements on early healthcare careers is unknown. Aim Explore whether a 5-week rural interprofessional education programme influenced graduates’ choices to work in primary care, rurally, and with Māori patients. Methods We conducted a survey-based, non-randomised trial of graduates from eight healthcare disciplines who did (n = 132) and did not (n = 479) attend the Tairāwhiti interprofessional education rural programme with hauora Māori placements. Participants were surveyed at 1-, 2-, and 3-years’ post-registration. Self-reported practice location and vocation were analysed with mixed-model logistic regression. Free-text comments were analysed with Template Analysis. Results We did not identify any measurable impact on rural or community workforce participation at 3-years’ post-registration. Free-text analysis indicated that a short rural interprofessional immersion placement had long-term self-perceived impacts on desire and skills to work in rural locations, and on desire and ability to work with Māori and embrace Māori models of health. Discussion Our study suggests that short rural immersion placements do not increase rural workforce participation during early healthcare careers. Three-years’ post-graduation may be too early to determine whether rural placements help to address rural health workforce needs. Reports from rural placement participants of increased ability to care for people from rural backgrounds, even when encountered in a city, suggest that assessment of practice location may not adequately capture the benefits of rural placement programmes.
