Investigating the December 2023 warm-to-cold weather whiplash in China using a novel flash-cold metric
Authors: Chen Huayu , Jiang Jilan , Liu Yimin 
Published: December 2024

Abstract
In mid-December 2023, China experienced an unprecedented cold wave that marked a critical stage in a negative temperature-related weather whiplash event (WWE), which was characterized by a rapid shift from extreme warmth to extreme cold. The traditional metric—temperature variance—is insufficient to reflect the temporal evolution of this WWE. Therefore, we introduce a novel metric termed ‘flash-cold’ to identify the sharp and significant decrease in surface air temperature. This new metric not only effectively captures recent WWEs trend in line with variance-based metric but also allows daily tracking of temperature shifts. Using the flash-cold metric, we delineate the evolution of the WWE case in China into four phases: first warm spell, first flash-cold, second warm spell, and second flash-cold (corresponding to the unprecedented cold wave). A recently proposed Lagrangian temperature budget analysis highlights the crucial role of high-latitude blocking circulation in both flash-cold phases through cold advection. The first flash-cold phase was triggered by backward cold air masses driven by upstream systems associated with Okhotsk blocking, while the second flash-cold phase developed when the trough downstream of Ural blocking moved eastward and rotated counterclockwise. In contrast, subtropical systems moderated the decreasing temperature during the first flash-cold through diabatic processes but had minimal impact on the second flash-cold, helping to explain why the second flash-cold was more intense. From a multiscale interaction perspective, the development of these blocking circulations was facilitated by a background of exceptionally weak meridional gradient of potential vorticity, the smallest recorded since 1979.
Using agent-based modelling to simulate the emission reduction potential of CCUS technologies in China under alternative policy packages

Abstract
Carbon capture, utilisation, and storage (CCUS) technologies are essential for achieving the 1.5 °C target. Predicting the emission reduction potential of CCUS technology is particularly important for countries to pursue carbon neutrality. However, the existing literature assessing the potential lacks consideration of the structural changes in industrial product demand and the trade-offs companies face between CCUS and traditional emission reduction technologies. This study used agent-based modelling (ABM) to simulate the emission reduction potential of CCUS in China’s thermal power, steel, cement, and chemical industries from 2022 to 2060 under scenarios of different carbon prices, subsidies, and technology progress rates. The possible biases of the traditional prediction model were corrected incorporating the structural changes in industrial product demand and the marginal abatement cost curves of traditional emission reduction technologies for the four major industries into the ABM model. The simulation results indicate that under each of the ten possible scenarios, China’s CCUS technologies will reach 100% penetration in the four mentioned industries by 2060, with the emission reduction potential fluctuating between 2222 and 1568 Mt of CO2 (corresponding to 40% and 10% share of thermal power, respectively). The difference comes in the scaled-up threshold time point and the growth trend. Sensitivity analyses show that the carbon price affects changes in the emission reduction potential of CCUS technologies the most, while the impact of subsidies, rates of technological progress and oil prices were not significant. The stepped carbon price policy can effectively regulate and promote the expansion of CCUS emission reduction potential, which is worth considering for policymakers.

Abstract
We study the dependence of recurrence coefficients in the three-term recurrence relation for orthogonal polynomials with a certain deformation of the q-Laguerre weight on the degree parameter n. We show that this dependence is described by a discrete Painlevé equation on the family of

This case study is a good illustration of the effectiveness of a recently proposed geometric identification scheme for discrete Painlevé equations.
On the maximally symmetric vacua of generic Lovelock gravities*
Authors: Devecioğlu Deniz Olgu , Lindström Ulf G , Sarıoğlu Özgür 
Published: December 2024

Abstract
We survey elementary features of Lovelock gravity and its maximally symmetric vacuum solutions. The latter is solely determined by the real roots of a dimension-dependent polynomial. We also recover the static spherically symmetric (black hole) solutions of Lovelock gravity using Palais’ symmetric criticality principle. We show how to linearize the generic field equations of Lovelock models about a given maximally symmetric vacuum, which turns out to factorize into the product of yet another dimension-dependent polynomial and the linearized Einstein tensor about the relevant background. We also describe how to compute conserved charges using linearized field equations along with the relevant background Killing isometries. We further describe and discuss the special vacua which are defined by the simultaneous vanishing of the aforementioned polynomials.

Published: December 2024

Abstract
Jiangxi Province, characterized by abundant forest resources and complex topography, is highly susceptible to forest fires. This study integrated multiple factors, including topography, climate, vegetation, and human activities, and employed machine learning models, specifically random forest (RF), support vector machine (SVM), and back-propagation neural network (BPNN), to predict forest fire occurrence in Jiangxi. Using Moderate Resolution Imaging Spectroradiometer L3 fire-point data from 2001–2020, we analyzed the spatiotemporal distribution of forest fires and applied the weight of evidence (WoE) method to evaluate the correlation between forest fires and environmental factors. WoE was employed to select negative samples, which were compared with those obtained using traditional random sampling methods. The optimal model was then utilized to generate seasonal spatial distribution maps of forest fire risk throughout Jiangxi Province. The results showed that over the past two decades, the frequency of forest fires generally decreased. RF demonstrated a significant advantage over SVM and BPNN in predicting forest fires. Vegetation coverage was the most influential factor. In addition, the models trained with WoE-selected negative samples exhibited enhanced accuracy, with area under the curve values increasing from 0.946 to 0.995 for RF, 0.8344 to 0.925 for SVM, and 0.832 to 0.850 for BPNN, compared to those trained with randomly sampled negative data. Finally, forest fires were most frequent during winter, particularly in Ganzhou, Fuzhou, and Ji'an. High-risk fire zones were more dispersed in spring, whereas autumn fires were primarily concentrated in Ganzhou, and fire activity was relatively low during summer. The seasonal forest fire risk maps generated in this study offer valuable insights for guiding forest fire management in the Jiangxi Province and similar regions, providing critical practical significance for informed decision-making.

Published: December 2024

Abstract
In this work, two crop soils were characterized: Querétaro (Bajío) and the State of Mexico (Edomex). Both states are part of the Sierra Madre Occidental, where temperate and subhumid climates are experienced. The surface soils are predominantly Leptosols in the Bajio and Andosols-Feozems in the Edomex. The dynamic mobility of water and fertilizers is associated with humic substances, mineralogical phases, metal dispersion, pore type, pore volume, and thermal behavior4

. Both agricultural soils exhibited high porosity and surfaces with co-dispersion of Al3+/Si4+ and Ti4+/Fe2+,3+ ions and mixed mineralogical phases such as montmorillonite, anorthite, quartz, magnetite, goethite, hematite, and kaolinite. On the one hand, the C/N values for the Bajio-crop and Edomex-crop soils showed values of 15 and 11, respectively. On the other hand, the Bajio-crop and Edomex-crop soils showed C/O values of 0.38 and 0.42, respectively, indicating the accumulation of organic carbon and the presence of various humic substances. Finally, the Bajio-crop soil presented a higher surface area, pore diameter, and pore volume than the Edomex-crop soil, which is associated with high adsorption and nutrient retention. On the contrary, the Edomex-crop soil presented greater thermal resistance than the Bajio-crop soil, which is associated with a better capacity for heat dissipation during irrigation processes or fertilizer application.
The Arrival of the Commercial Institutional Logic
Authors: Sytch Maxim 
Published: December 2024

Abstract
This chapter begins to uncover the motivations behind supplier-induced demand, locating them at the intersection of structure and agency, stemming from the shift in institutional logics in professional services. Institutional logics delineate the practices, norms, and cognitive perspectives ingrained within our work environments, shaping our perceptions of the work itself. Since the 1980s, professional services have undergone a profound transformation from an advisory institutional logic to a commercial one. These changes have permeated virtually every aspect of professional services, giving rise to sophisticated managerial structures and previously counter normative practices, such as external ownership, marketing one’s services, linking partnership status to partners’ ongoing productivity, recruiting rainmakers from rival firms, and embracing market-oriented principles in pursuit of growth and profitability. This shift in institutional logics has laid a powerful foundation for how professionals began to see their roles and work.
The Deuteragonist Self
Authors: Anooshahr Ali 
Published: December 2024

Abstract
This chapter shows how Jawhar negated the conditions of slavery by writing and constructing narrative “selves” for himself and the emperor. While the emperor was the protagonist, Jawhar was the secondary character or “deuterogonist” who accompanied the master, told his story, but also inserted himself in the chronicle of events as a capable and dutiful companion. Jawhar was able to do this in part thanks to his exposure of Shattari Sufism at the imperial court, to his exposure to Chishti hagiography in Delhi, and to his experience of writing reports to the emperor about his service as an administrator later in life.
Hospitality and Exile
Authors: Anooshahr Ali 
Published: December 2024

Abstract
Jawhar provides the most detailed account of Emperor Humayun’s sojourn in Iran in the 1540s. His interpretive framework of his and the emperor’s sojourn in Iran was deeply informed by the pre-modern notions of hospitality and exile. Hospitality was a contractual obligation between lineages not entire people or states. The host needed to remember that his fortunes might be reversed, and that he might expect the guest to return the favor in the future. Mutual obligations were sacred. However, the early sixteenth century was also witnessing the rise of centralized early modern states, and the “reason of state” was competing with the rites of hospitality at this time.
Developing an artificial diet for rearing Ganaspis brasiliensis (Hymenoptera: Figitidae) on spotted-wing drosophila
Authors: Aly Marwa F K , Burrack Hannah J , Isaacs Rufus 
Published: December 2024

Abstract
Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a global invasive pest attacking soft-skinned fruit. The specialist larval parasitoid wasp, Ganaspis brasiliensis (Ihering), was recently approved in Europe and the United States for classical biological control releases against D. suzukii. Rearing methods are essential for supporting innundative releases but current methods using fresh fruit are costly and susceptible to variation in host quality. To develop an artificial rearing system, we first compared the performance and development of D. suzukii and G. brasiliensis on fresh raspberries and blueberries and then on various artificial diet shapes and volumes. Drosophila suzukii had 1–2 days shorter development times in raspberry than blueberry, whereas Ganaspis adult development time was similar in both fruit and averaged 25 days. Parasitism rates by G. brasiliensis were significantly higher in blueberry than raspberry in both small and large resource patches. We found that D. suzukii preferred to lay eggs in full sphere diet shapes than in flat diet circles or semisphere diet, and in the first trial with wasps parasitism was only found on D. suzukii larvae in the full sphere shape of raspberry diet. Comparison of parasitism on full sphere raspberry and blueberry diets found higher parasitism in raspberry compared to blueberry diet. Our results indicate potential for further improvement of artificial rearing systems for G. brasiliensis to allow more cost-effective and reliable rearing for biological control programs.
Resilience in Environmental History Discourse
Authors: Mordechai Lee , Haldon John 
Published: December 2024

Abstract
Resilience is a boundary object, holding different meanings for the different groups of scholars who share its use. Here we survey its application in historical research, especially premodern environmental history, and trace how the term entered historical discourse from ecology. A shift in recent decades expanded the term initially toward contemporary social science and subsequently the study of the past. This has resulted in a fuzzy conceptualization of the term within historical discourse. Yet the concept has nevertheless proven important in challenging catastrophist approaches to the societal impacts of environmental stressors (e.g., the fall of the Roman Empire). We demonstrate that today’s discussion continues an earlier twentieth-century debate between an environmentally determinist view and one that emphasizes the role of human factors in the course of history. We conclude that despite the issues accompanying the use of the term and the application of formal resilience theory, both remain valuable, especially in intradisciplinary discourse, primarily as a paradigm through which more nuanced arguments can be framed. We conclude by suggesting the value of more critical work with the term in the future to take advantage of its roots in ecology and the social sciences to promote such a nuanced synthesis.
Kenyan Nubians and the Myth of Nubian Resilience
Authors: Wilks Tammy 
Published: December 2024

Abstract
Often defined and examined as a human characteristic enacted under duress, resilience receives little attention as to how, why, and for whom it is valued. By exploring resilience as a colonial myth or discursive device, this article investigates how racialized ideas of the late nineteenth century informed the way colonial actors in present-day Kenya and East Africa classified and regulated communities according to who counted as “resilient.” It traces the particular myth of Nubian resilience to illustrate how the idea of Nubian soldiers’ exceptionalism among African troops informed, authorized, and at times undermined the colonial project in Kenya as well as the political realities of Nubian soldiers. Drawing on the colonial archive, oral history of the Kenyan Nubian Council of Elders, and ethnography, this article outlines how multiple and often competing versions of the myth of Nubian resilience co-existed throughout the history of Kenya, and concludes with an analysis of how the myth of Nubian resilience is remembered in postcolonial Kenya.
Recognition as Resilience
Authors: Renoir Megan , Covert Shelly 
Published: December 2024

Abstract
Resilience has been conceptualized within international development as the ability to “return to a state of equilibrium” after exogenous shocks. For many Indigenous communities, however, there is no equilibrium to which to return. This article explores how the federally unrecognized Nevada City Rancheria Nisenan Tribe (NCRNT) has developed a creative strategy of resilience beyond a return to “equilibrium” in the face of their almost complete erasure by genocide and the illegal termination of their sovereign rights by US state and federal government agencies. The NCRNT’s experience reveals how activities underlying Indigenous resilience include a need for historical redress and reconciliation, thereby creating a “new normal” that is reflective of Native history as well as the ongoing social, political, and economic realities of existing within a settler state. This article bridges history and development studies, revealing how both disciplines must learn from Indigenous groups seeking restorative justice. It further employs oral histories, artwork, and documentation from the newly created NCRN Tribal archive, and so is presented as an interactive digital article.
Urbanization and environmental variation drive phenological changes in the spotted lanternfly, Lycorma delicatula (Hemiptera: Fulgoridae)
Authors: Owen Hannah L , Meng Fang , Winchell Kristin M 
Published: December 2024

Abstract
The spotted lanternfly (Lycorma delicatula) invaded the USA in 2014. The population has grown into the millions and spread across multiple states, primarily in the north-east but extending into the midwest. We analysed nearly 20 000 records of spotted lanternflies from the citizen-science platform iNaturalist across all reported locations in the USA to explore spatiotemporal patterns of activity and abundance as the invasion progresses. Observations on iNaturalist are consistent with reports of rapid exponential growth in the early years of the invasion. However, in the oldest parts of the invasive range, abundance exhibits logarithmic growth suggestive of reaching carrying capacity in these regions. Since 2015, observed activity has shifted earlier each year and life-cycle stages have lengthened concurrent with a general northern expansion. Activity patterns were correlated with urbanization generally, and earlier activity was associated with higher temperatures in both urban and non-urban locations. Together, these findings suggest that urbanization, and the urban heat island in particular, could facilitate invasion into colder climates and beyond predictions based on current occupancy. Understanding how life-cycle timing is shifting as the invasion progresses, in addition to the environmental factors shaping these changes, underscores the importance of integrating evolutionary ecology into invasion forecasts.

Published: December 2024

Abstract
Multienergy cardiovascular CT imaging can be defined as data acquisition at 2 (dual-energy) or multiple X-ray energies. Multienergy cardiovascular CT imaging provides additional qualitative and quantitative information such as material maps or virtual monoenergetic images, which are supposed to further improve the quality and diagnostic yield of CT. Recently introduced photon-counting detector CT scanners further address some of the challenges and limitations of previous, conventional CT machines, hereby enhancing and extending the applications of CT for cardiovascular imaging. This review summarizes the technical principles of multienergy cardiovascular CT imaging and addresses the optimization of image quality and discusses the various dual-energy-based applications for coronary, valvular, and myocardial imaging. New developments in regard to k-edge imaging and new contrast media for multienergy cardiovascular CT imaging are being also discussed.

Abstract

Background
There are differences in oesophageal cancer care across Sweden. According to national guidelines, all patients should be offered equal care, planned and administrated by regional multidisciplinary team meetings. The aim of the study was to investigate differences between regional multidisciplinary team meetings in Sweden regarding clinical staging and treatment recommendations for oesophageal cancer patients.

Methods
All six Swedish regional multidisciplinary teams were each invited to retrospectively include ten consecutive oesophageal cancer cases. After anonymization, radiological investigations were presented, along with the original case-specific medical history, anew at the participating regional multidisciplinary team meetings. Estimation of clinical tumour node metastasis (TNM) classification and treatment recommendation (curative, palliative or best supportive care) were compared between multidisciplinary team meetings as well as with original assessments.

Results
Five multidisciplinary teams participated and contributed a total of 50 cases presented to each multidisciplinary team. In estimations of cT-stage, the multidisciplinary teams were in total agreement in only eight of 50 cases (16%). For cN-stage, total agreement was seen in 17 of 50 cases (34%) and for cM-stage there was agreement in 34 cases (68%). For cT-stage, the overall summarized κ value was 0.57. For N-stage and M-stage the κ values were 0.66 and 0.78 respectively. Differences in appraisal were not associated with usage of positron emission tomography-computed tomography. In 15 of 50 cases (30%) the multidisciplinary teams disagreed on curative or palliative treatment.

Conclusion
The study shows differences in assessment of clinical TNM classification and treatment recommendations made at regional multidisciplinary team meetings. Increased interrater agreement on clinical TNM classification and management plans are essential to achieve more equal care for oesophageal cancer patients in Sweden.
