An Ethos and Practice of Appreciation for Transformative Research: Appreciative Inquiry, Care Ethics, and Creative Methods
Authors: Moriggi Angela 
Published: December 2021

AbstractThis chapter departs from the need to pursue transformative research, understood as the co-production of knowledge with and for societal stakeholders aimed at supporting and enabling sustainable change. It explores how Appreciative Inquiry (AI) and its underlying ‘ethos of appreciation’ (after Zandee & Cooperrider, 2008) can complement and enrich care-full and resourceful approaches to transformative research. It presents the five dimensions of an ‘ethos of appreciation’, and lays out their philosophical meaning, their resonance with the care ethics literature, as well as their practical application. It gives a detailed account of how five different creative methods were employed during a participatory action-oriented Ph.D. study in Finland, and in so doing, showcases how an ‘ethos of appreciation’ can be embodied and applied in practice. Finally, it discusses the methodological potentials and limitations of using creative methods, as well as the challenges and outcomes they yield to support transformative research that aims to enable care-full and resourceful participatory engagement processes.
Standard Model EFTs via on-shell methods
Authors: Huber Manuel Accettulli , De Angelis Stefano 
Published: December 2021

Abstract
We present the Standard Model Effective Field Theories (SMEFT) from purely on-shell arguments. Starting from few basics assumptions such as Poincaré invariance and locality, we classify all the renormalisable and non-renormalisable interactions at lowest order in the couplings. From these building blocks, we review how locality and unitarity enforce Lie algebra structures to appear in the S-matrix elements together with relations among couplings (and hypercharges). Furthermore, we give a fully on-shell algorithm to compute any higher-point tree-level amplitude (or form factor) in generic EFTs, bypassing BCFW-like recursion relations which are known to be problematic when non-renormalisable interactions are involved. Finally, using known amplitudes techniques we compute the mixing matrix of SMEFT marginal interactions up to mass dimension 8, to linear order in the effective interactions.
Dijet impact factor in DIS at next-to-leading order in the Color Glass Condensate
Authors: Caucal Paul , Salazar Farid , Venugopalan Raju 
Published: December 2021

AbstractWe compute the next-to-leading order impact factor for inclusive dijet production in deeply inelastic electron-nucleus scattering at smallxBj. Our computation, performed in the framework of the Color Glass Condensate effective field theory, includes all real and virtual contributions in the gluon shock wave background of all-twist lightlike Wilson line correlators. We demonstrate explicitly that the rapidity evolution of these correlators, to leading logarithmic accuracy, is described by the JIMWLK Hamiltonian. When combined with the next-to-leading order JIMWLK Hamiltonian, our results for the impact factor improve the accuracy of the inclusive dijet cross-section to$$ \mathcal{O} $$O($$ {\alpha}_s^2 $$αs2ln(xf/xBj)), wherexfis a rapidity factorization scale. These results are an essential ingredient in assessing the discovery potential of inclusive dijets to uncover the physics of gluon saturation at the Electron-Ion Collider.
Brown-York charges with mixed boundary conditions
Authors: Odak Gloria , Speziale Simone 
Published: December 2021

Abstract
We compute the Hamiltonian surface charges of gravity for a family of conservative boundary conditions, that include Dirichlet, Neumann, and York’s mixed boundary conditions defined by holding fixed the conformal induced metric and the trace of the extrinsic curvature. We show that for all boundary conditions considered, canonical methods give the same answer as covariant phase space methods improved by a boundary Lagrangian, a prescription recently developed in the literature and thus supported by our results. The procedure also suggests a new integrable charge for the Einstein-Hilbert Lagrangian, different from the Komar charge for non-Killing and non-tangential diffeomorphisms. We study how the energy depends on the choice of boundary conditions, showing that both the quasi-local and the asymptotic expressions are affected. Finally, we generalize the analysis to non-orthogonal corners, confirm the matching between covariant and canonical results without any change in the prescription, and discuss the subtleties associated with this case.
Radiated momentum in the post-Minkowskian worldline approach via reverse unitarity
Authors: Riva Massimiliano Maria , Vernizzi Filippo 
Published: December 2021

AbstractWe compute the four-momentum radiated during the scattering of two spinless bodies, at leading order in the Newton’s contantGand at all orders in the velocities, using the Effective Field Theory worldline approach. Following [1], we derive the conserved stress-energy tensor linearly coupled to gravity generated by localized sources, at leading and next-to-leading order inG, and from that the classical probability amplitude of graviton emission. The total emitted momentum is obtained by phase-space integration of the graviton momentum weighted by the modulo squared of the radiation amplitude. We recast this as a two-loop integral that we solve using techniques borrowed from particle physics, such as reverse unitarity, reduction to master integrals by integration-by-parts identities and canonical differential equations. The emitted momentum agrees with recent results obtained by other methods. Our approach provides an alternative way of directly computing radiated observables in the post-Minkowskian expansion without going through the classical limit of scattering amplitudes.
Technology-based approaches toward a better understanding of neuro-coagulation in brain homeostasis
Authors: Maoz Ben M. , Asplund Maria , Maggio Nicola , Vlachos Andreas 
Published: December 2021

AbstractBlood coagulation factors can enter the brain under pathological conditions that affect the blood–brain interface. Besides their contribution to pathological brain states, such as neural hyperexcitability, neurodegeneration, and scar formation, coagulation factors have been linked to several physiological brain functions. It is for example well established that the coagulation factor thrombin modulates synaptic plasticity; it affects neural excitability and induces epileptic seizures via activation of protease-activated receptors in the brain. However, major limitations of current experimental and clinical approaches have prevented us from obtaining a profound mechanistic understanding of “neuro-coagulation” in health and disease. Here, we present how novel human relevant models, i.e., Organ-on-Chips equipped with advanced sensors, can help overcoming some of the limitations in the field, thus providing a perspective toward a better understanding of neuro-coagulation in brain homeostasis.
Challenges and opportunities of area-based conservation in reaching biodiversity and sustainability goals
Authors: Hoffmann Samuel 
Published: December 2021

AbstractArea-based conservation is essential to safeguard nature’s diversity. In view of expanding human land use, increasing climate change and unmet conservation targets, area-based conservation requires efficiency and effectiveness more than ever. In this review, I identify and relate pressing challenges to promising opportunities for effective and efficient protected area governance and management, to enhance research, decision-making and capacity building in area-based conservation under uncertain future developments. I reveal that protected area management is particularly challenged by human land use, climate change, invasive species, and social, political and economic limitations. Protected area management often lacks the continuous availability of data on current states and trends of nature and threats. Biocultural conservation, climate-smart management and biosecurity approaches help to overcome challenges induced by human needs, climate change and invasive species, respectively. Economic valuation and shifts in funding priorities can boost protected area effectiveness and efficiency. In-situ monitoring techniques, remote sensing and open data infrastructures can fill data and information gaps for protected area planning and management. Moreover, adaptive management is an auspicious concept in the framework of systematic conservation planning to ensure the enduring effectiveness of protected areas despite unpredictable future developments. Post-2020 international biodiversity and sustainable development goals could be met earlier if protected areas were more effective. I consequently conclude with the need for a global information system that is to support area-based conservation by synthesizing challenges and opportunities for protected area management effectiveness and efficiency at the local to global level.

Abstract
Purpose
To explore the effect of type 2 diabetes mellitus (T2DM) on the risk of death among women with breast cancer (BC).

Methods
A survival analysis was conducted among a cohort of women diagnosed with BC between 2006 and 2012 in Spain (n = 4,493). Biopsy or surgery confirmed BC cases were identified through the state population-based cancer registry with information on patients’ characteristics and vital status. Physician-diagnosed T2DM was confirmed based on primary health care clinical history. Cox regression analyses were used to estimate adjusted hazard ratios (aHR) and 95% confidence intervals (CI) for all-cause death. Analyses were adjusted for age, hospital size, several clinical characteristics (including BC stage and histology, among others) and treatment modalities.

Results
Among the 4,493 BC women, 388 (8.6%) had coexisting T2DM. Overall, 1,299 (28.9%) BC women died during the completion of the follow-up and 785 (17.5%) did so during the first five years after BC diagnosis, resulting in a five-year survival rate of 82.5%. The death rate was higher in women with T2DM (43.8% died during whole period and 26.0% during the first five years) when compared with women without T2DM (27.5% and 16.7%, respectively). Accordingly, all-cause mortality was higher in women with T2DM (aHR: 1.22; 95% CI 1.03–1.44), especially if T2DM was diagnosed before BC (aHR:1.24; 95% CI 1.03–1.50) and in women with BC diagnosed before 50 years (aHR: 2.38; 95% CI 1.04–5.48).

Conclusions
T2DM was associated with higher all-cause mortality among Spanish women with BC, particularly when the T2DM diagnosis was prior to the BC.

AbstractSome of the major discoveries of the recent Cassini-Huygens mission have put Titan and Enceladus firmly on the Solar System map. The mission has revolutionised our view of Solar System satellites, arguably matching their scientific importance with that of their host planet. While Cassini-Huygens has made big surprises in revealing Titan’s organically rich environment and Enceladus’ cryovolcanism, the mission’s success naturally leads us to further probe these findings. We advocate the acknowledgement of Titan and Enceladus science as highly relevant to ESA’s long-term roadmap, as logical follow-on to Cassini-Huygens. In this White Paper, we will outline important science questions regarding these satellites and identify the science themes we recommend ESA cover during the Voyage 2050 planning cycle. Addressing these science themes would make major advancements to the present knowledge we have about the Solar System, its formation, evolution, and likelihood that other habitable environments exist outside the Earth’s biosphere.
Need satisfaction and achievement goals of university faculty: an international study of their interplay and relevance

Published: December 2021

AbstractPrevious research has successfully used basic psychological need satisfaction and achievement goal approaches for describing the motivations of university faculty for teaching and for explaining differences in faculty experiences, success, and learning. However, the interplay between these motivational constructs has been largely ignored, with only faculty from specific educational contexts being studied—neglecting those from other higher education systems and institution types that potentially differ in the configurations, levels, and effects of their motivations. As combining both approaches and examining multiple educational contexts is essential for a comprehensive theoretical understanding of faculty motivation and generalizable results, we conducted an international study including 1410 university faculty members from German, Indian, and US-American teaching and research universities. Aside from need satisfaction and achievement goals, we measured their positive affect, teaching quality, and professional learning. Results demonstrated measurement invariance of basic need and achievement goal scales regarding language, higher education context, and institution type. We found small differences in motivations between the three higher education contexts and negligible differences between institution types. Task, learning, and relational goals were positively and work avoidance goals were negatively linked to the outcome variables. Need satisfaction sensibly explained differences in pursuit of these goals, and—directly and indirectly through the goals—also the outcome variables. Taken together, these results provide international evidence for the importance of faculty motivation for teaching and illuminate how need satisfaction is relevant for goal pursuit, while both motivation approaches uniquely matter for faculty experiences, success, and learning.

AbstractIn this paper, we propose a mosquito population suppression model which is composed of two sub-models switching each other. We assume that the releases of sterile mosquitoes are periodic and impulsive, only sexually active sterile mosquitoes play a role in the mosquito population suppression process, and the survival probability is density-dependent. For the release waiting period T and the release amount c, we find three thresholds denoted by $$T^*$$

Published: December 2021

AbstractRecent observations from Parker Solar Probe have revealed that the solar wind has a highly variable structure. How this complex behaviour is formed in the solar corona is not yet known, since it requires omnipresent fluctuations, which constantly emit material to feed the wind. In this article we analyse 14 upflow regions in the solar corona to find potential sources for plasma flow. The upflow regions are derived from spectroscopic data from the EUV Imaging Spectrometer (EIS) on board Hinode determining their Doppler velocity and defining regions which have blueshifts stronger than $-6~\mbox{km}\,\mbox{s}^{-1}$

. To identify the sources of these blueshift data from the Atmospheric Imaging Assembly (AIA) and the Helioseismic and Magnetic Imager (HMI), on board the Solar Dynamics Observatory (SDO), and the X-ray Telescope (XRT), on board Hinode, are used. The analysis reveals that only 5 out of 14 upflows are associated with frequent transients, like obvious jets or bright points. In contrast to that, seven events are associated with small-scale features, which show a large variety of dynamics. Some resemble small bright points, while others show an eruptive nature, all of which are faint and only live for a few minutes; we cannot rule out that several of these sources may be fainter and, hence, less obvious jets. Since the complex structure of the solar wind is known, this suggests that new sources have to be considered or better methods used to analyse the known sources. This work shows that small and frequent features, which were previously neglected, can cause strong upflows in the solar corona. These results emphasise the importance of the first observations from the Extreme-Ultraviolet Imager (EUI) on board Solar Orbiter, which revealed complex small-scale coronal structures.
Evaluation of historical CMIP6 model simulations and future projections of temperature over the Pan-Third Pole region
Authors: Fan Xuewei , Duan Qingyun , Shen Chenwei , Wu Yi , Xing Chang 
Published: December 2021

AbstractThe Pan-Third Pole (PTP) region, which encompasses the Eurasian highlands and their surroundings, has experienced unprecedented, accelerated warming during the past decades. This study evaluates the performance of historical simulation runs of the Coupled Model Intercomparison Project (CMIP6) in capturing spatial patterns and temporal variations observed over the PTP region for mean and extreme temperatures. In addition, projected changes in temperatures under four Shared Socioeconomic Pathway (SSP) scenarios (SSP1‐2.6, SSP2‐4.5, SSP3-7.0, and SSP5‐8.5) are also reported. Four indices were used to characterize changes in temperature extremes: the annual maximum value of daily maximum temperature (TXx), the annual minimum value of daily minimum temperature (TNn), and indices for the percentage of warm days (TX90p) and warm nights (TN90p). Results indicate that most CMIP6 models generally capture the characteristics of the observed mean and extreme temperatures over the PTP region, but there still are slight cold biases in the Tibetan Plateau. Future changes of mean and extreme temperatures demonstrate that a strong increase will occur for the entire PTP region during the twenty-first century under all four SSP scenarios. Between 2015 and 2099, ensemble area-averaged annual mean temperatures are projected to increase by 1.24 °C/100 year, 3.28 °C/100 year, 5.57 °C/100 year, and 7.40 °C/100 year for the SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5 scenarios, respectively. For TXx and TNn, the most intense warming is projected in Central Asia. The greatest number of projected TX90p and TN90p will occur in the Southeast Asia and Tibetan Plateau, respectively.
Learning about the nature of science through the critical and reflective reading of news on the COVID-19 pandemic
Authors: García-Carmona Antonio 
Published: December 2021

AbstractThe global COVID-19 pandemic caused by the SARS-CoV-2 virus has led to a plethora of information published in the media. Conceived as a socioscientific issue of great relevance currently, this article highlight the educational potential of some media news about the pandemic to reflect and learn about the nature of science (NOS). To this end, a theoretical foundation is first presented regarding the reading of science news published in the media as an educational resource to learn about NOS. Secondly, a proposal is presented on how this might be addressed in the science classroom. The proposal is illustrated by four news items, intentionally selected as examples, which have been published in the Spanish digital press. The aspects of NOS that are discussed in the context of the news items selected are: tentativeness of scientific knowledge, role of error in scientific research, role of debate in the development of science, importance of models and modelling in scientific research, and ethics in science.
Automated SEM/EDS Analysis for Assessment of Trace Cross-Contamination in 316L Stainless Steel Powders
Authors: Balart MarÍa J. , Hao Xinjiang , Davis Claire L. 
Published: December 2021

Abstract
Following observations of microcracking in two, out of three, Additive manufactured (AM) 316L steel samples, an investigation was undertaken to ascertain the root cause. Welding diagrams, taking into account composition and process parameters, could not generally account for the experimental observations of non-cracked versus cracked AM 316L samples. EBSD phase maps in all three AM samples exhibited a fully austenitic microstructure not only in the bulk sample but also near-surface. Analysis of microcracked regions in the AM samples showed the presence of local enrichment of Ni, Cu and P. Automated SEM/EDS analysis on feedstock powder samples prepared for cross-section examination revealed a fine, foreign particulate contaminant, expected to arise from NiCrCuP alloy cross-contamination during atomization, to be completely embedded in a 316L powder particle. This type of contamination would not have been revealed on examination of powder mounted onto a SEM stub, a common approach to assess powder quality. Based on this analysis, it is recommended to consider including automated SEM/EDS analysis on powder cross-sections in any standardization protocol for quality control of powders, to increase the chances of detection and identification of fine cross-contaminants. It is also recommended that atomization of NiCrCuP alloy should no longer precede atomization of 316L alloy.

Published: December 2021

AbstractOxide-containing films were made by reactively sputtering a high-entropy alloy target of CrFeCoNiCu. We report on a wide range of changes to the electrical properties made by different heat treatments in oxidizing and reducing atmospheres, respectively. We combine temperature-dependent Hall effect measurements down to 10 K to study the transport mechanisms and correlate that with structural measurements by x-ray diffraction and scanning electron microscopy. The measured/effective resistivity could be varied between 1.3 × 10−4 Ω cm and 1.2 × 10−3 Ω cm by post-deposition processing. The temperature coefficient of resistivity could be varied between − 1.2 × 10−3 K−1 through 0 and to + 0.7 × 10−3 K−1. The key to the variation is controlling the morphology and topology of the film. The conduction of charge carriers is dominated by the relative contribution of weak localization and alloy scattering by varying the degree of disorder in the metallic high-entropy alloy and its topology.
