Leopards at large: population density, habitat utilisation and spatio-temporal overlap of leopards (Panthera pardus) with competitors and prey in the Rajaji Tiger Reserve, northern India
Authors: Yadav Shashank , Mohan Manu , Sharma Aditi , Sonker Sanatan , Krishnamurthy Ramesh 
Published: June 2024

Context In the vicinity of the western Rajaji Tiger Reserve, a significant rise in conflicts between humans and leopards has occurred. These conflicts have resulted in a substantial number of human deaths, with 60% attacks resulting in deaths over a 4-year period. Aims This study aims to examine any potential connection among the non-breeding tigers, leopards, prey, humans and the increased occurrence of conflicts. Methods To address this objective, we conducted an analysis to evaluate the density of leopards, as well as their spatial and temporal behaviour with respect to tigers, prey and humans through on-site habitat use, circular statistics, diel-overlap as well spatial niche breadth and spatial-niche overlap. Key results Our findings showed one of the highest leopard-density estimates (excluding cubs) (mean ± s.e.) of 23.7 ± 4.8 per 100 km2. When examining on-site habitat use by leopards, we found three variables that had a negative influence, namely, human presence, slope, and the presence of tigers. The presence of a large prey (sambar) had a positive influence. Leopards, exhibiting the highest spatial-niche breadth, demonstrated a small overlap with both tigers and humans, while displaying a significant diel overlap with sambar. The niche overlap was notably high with sambar, but very low with humans and tigers. Conclusions Although tigers locally created a zone of spatial and temporal avoidance, at the population level the leopards experienced a surge in numbers in response to the reduced tiger numbers, indicated by their high density. This could be a cause of high leopard movement into nearby human settlements. This unique scenario could have contributed to conflict. Implications Understanding the coexistence among different species and the impact of transient animals is crucial to develop effective management strategies to mitigate conflict. This approach would facilitate and ensure the long-term survival of diverse large carnivores in the tropical forests of southern Asia through sustained support for conservation from local communities.
Representation of migrant accents in media discourse
Authors: Dumlao Remart Padua , Willoughby Louisa 
Published: June 2024

AbstractThis study looks at how migrants’ accents are portrayed, labelled, and constructed in media discourse, investigating media coverage of migrants’ accents in the Australian press from 2007 to 2017, a period highlighted by changes in Australian citizenship policies and public discourse. While language has been extensively discussed in policy discourse, there has been a notable dearth of research on the coexistence of dialects and accents within official languages as portrayed in media platforms. Using a corpus-assisted critical discourse analysis of 2,657,016 words from Australian newspaper articles, the study applies raciolinguistic ideologies to show how the press justifies and legitimizes migrant accent-related issues. The results suggest that speakers of Inner Circle English variants are positioned differently from non-white/Outer and Expanding Circle speakers. Speakers of the Inner Circle were far more likely than other speakers to have their accents described as ‘broad’ or ‘thick’, and they were more likely to have the national variation they spoke specifically named. Others, in contrast, regularly described racialized speakers as simply having a ‘foreign’ accent, and many of them frequently claimed trying to ‘change’ their accent or ‘fake’ an Australian accent in an effort to gain access to employment and broader social acceptance. These results emphasize the subtle and not-so-subtle ways that non-white migrant speakers are positioned as incompetent speakers and demonstrate how raciolinguistic ideologies, linguistic racism, and accent laboring concerns are widespread in Australian society. These findings highlight the significance of corpus approaches for studying language related issues and provide insight into accent biases produced by the media in Australian society.
The invitation game

Published: June 2024

Abstract
This paper analyses Danish Tinder chats that in the very first message after ‘matching’ immediately launch the
prospect of meeting. A collection of 41 threads is analyzed using Goffman’s (1967, 1974) concepts of face and interactional framing, outlining
methods participants use to open a chat after having matched and addressing the interest and purpose they have approached in the
other party. Methods include, in particular, inferences that can be made based on the type of activity or setting suggested for a
future meeting, indirectness and ambiguity related to how the social actions are designed, and the conversational cues used such
as emojis and enthusiasm markers. The analysis also shows how participants work out and negotiate whether they have a common
interest in meeting, in particular, how they exploit and deal with ambiguities used extensively as a mechanism for flirting. The
analysis further suggests that practices adhere to gender-stereotypes showing how participants may handle and orient to a norm
that women should not agree to meet with a stranger early on in a chat correspondence.
Light quarkonium and charmonium mass shifts in an unquenched quark model*
Authors: Chen 陈 Xiaoyun 晓云 , Tan 谭 Yue 悦 
Published: June 2024

Abstract
The unquenched quark model for the light quarkonium and charmonium states is explored in this study. The quark-pair creation operator in the

model, which combines the two-quark and four-quark components, is modified by considering the effects of the created quark pair's energy. Furthermore, the separation between the created quark pair and valence quark pair is modified. All the wave functions, including those for the mesons and the relative motion between two mesons, are obtained by solving the corresponding Schrödinger equation using the Gaussian expansion method. The aim of this study is to find a new set of parameters that can accurately describe the mass spectrum of low-lying light quarkonium and charmonium states. Moreover, certain exotic states, such as

, can be described well in the unquenched quark model.
A simple light path modifying device to reduce scattering in front-face fluorescence spectra
Authors: Peters Frank B , Rapp Andreas O 
Published: June 2024

Abstract
This technical note presents a device to diminish scattering signal in front-face fluorescence spectra while obtaining fluorescence signal. The beam path in a commercial fluorescence spectrometer was modified by two deflecting mirrors, leading reflections away from the sensor. This light path modifying (LPM) device was tested with two fluid and three solid substances, where the scattering-to-fluorescence ratio improved by a factor of 1.7 to 7.6. The spectra obtained with the LPM were much clearer, and distortion of the fluorescence peaks was avoided. Scans of quinine sulphate complied well with reference spectra.
Merging automatic differentiation and the adjoint method for photonic inverse design
Authors: Luce Alexander , Alaee Rasoul , Knorr Fabian , Marquardt Florian 
Published: June 2024

Abstract
Optimizing the shapes and topology of physical devices is crucial for both scientific and technological advancements, given their wide-ranging implications across numerous industries and research areas. Innovations in shape and topology optimization have been observed across a wide range of fields, notably structural mechanics, fluid mechanics, and more recently, photonics. Gradient-based inverse design techniques have been particularly successful for photonic and optical problems, resulting in integrated, miniaturized hardware that has set new standards in device performance. To calculate the gradients, there are typically two approaches: namely, either by implementing specialized solvers using automatic differentiation (AD) or by deriving analytical solutions for gradient calculation and adjoint sources by hand. In this work, we propose a middle ground and present a hybrid approach that leverages and enables the benefits of AD for handling gradient derivation while using existing, proven but black-box photonic solvers for numerical solutions. Utilizing the adjoint method, we make existing numerical solvers differentiable and seamlessly integrate them into an AD framework. Further, this enables users to integrate the optimization environment seamlessly with other autodifferentiable components such as machine learning, geometry generation, or intricate post-processing which could lead to better photonic design workflows. We illustrate the approach through two distinct photonic optimization problems: optimizing the Purcell factor of a magnetic dipole in the vicinity of an optical nanocavity and enhancing the light extraction efficiency of a µLED.
On the prediction of the turbulent flow behind cylinder arrays via echo state networks
Authors: Ghazijahani M Sharifi , Cierpka C 
Published: June 2024

Abstract
This study aims at the prediction of the turbulent flow behind cylinder arrays by the application of Echo State Networks (ESN). Three different arrangements of arrays of seven cylinders are chosen for the current study. These represent different flow regimes: single bluff body flow, transient flow, and co-shedding flow. This allows the investigation of turbulent flows that fundamentally originate from wake flows yet exhibit highly diverse dynamics. The data is reduced by Proper Orthogonal Decomposition (POD) which is optimal in terms of kinetic energy. The Time Coefficients of the POD Modes (TCPM) are predicted by the ESN. The network architecture is optimized with respect to its three main hyperparameters, Input Scaling (INS), Spectral Radius (SR), and Leaking Rate (LR), in order to produce the best predictions in terms of Weighted Prediction Score (WPS), a metric leveling statistic and deterministic prediction. In general, the ESN is capable of imitating the complex dynamics of turbulent flows even for longer periods of several vortex shedding cycles. Furthermore, the mutual interdependencies of the TCPM are well preserved. However, optimal hyperparameters depend strongly on the flow characteristics. Generally, as flow dynamics become faster and more intermittent, larger LR and INS values result in better predictions, whereas less clear trends for SR are observable.
Kicking the can down the road: understanding the effects of delaying the deployment of stratospheric aerosol injection

Published: June 2024

Abstract
Climate change is a prevalent threat, and it is unlikely that current mitigation efforts will be enough to avoid unwanted impacts. One potential option to reduce climate change impacts is the use of stratospheric aerosol injection (SAI). Even if SAI is ultimately deployed, it might be initiated only after some temperature target is exceeded. The consequences of such a delay are assessed herein. This study compares two cases, with the same target global mean temperature of ∼1.5° C above preindustrial, but start dates of 2035 or a ‘delayed’ start in 2045. We make use of simulations in the Community Earth System Model version 2 with the Whole Atmosphere Coupled Chemistry Model version 6 (CESM2-WACCM6), using SAI under the SSP2-4.5 emissions pathway. We find that delaying the start of deployment (relative to the target temperature) necessitates lower net radiative forcing (−30%) and thus larger sulfur dioxide injection rates (+20%), even after surface temperatures converge, to compensate for the extra energy absorbed by the Earth system. Southern hemisphere ozone is higher from 2035 to 2050 in the delayed start scenario, but converges to the same value later in the century. However, many of the surface climate differences between the 2035 and 2045 start simulations appear to be small during the 10–25 years following the delayed SAI start, although longer simulations would be needed to assess any longer-term impacts in this model. In addition, irreversibilities and tipping points that might be triggered during the period of increased warming may not be adequately represented in the model but could change this conclusion in the real world.
Human-induced climate change has decreased wheat production in northern Kazakhstan
Authors: Romanovska Paula , Undorf Sabine , Schauberger Bernhard , Duisenbekova Aigerim , Gornott Christoph 
Published: June 2024

Abstract
Northern Kazakhstan is a major wheat exporter, contributing to food security in Central Asia and beyond. However, wheat yields fluctuate and low-producing years occur frequently. It is currently unclear to what extent human-induced climate change contributes to this. The most severe low-producing year in this century was in 2010, which had severe consequences for the food security of wheat-importing countries. Here, we present a climate impact attribution study that quantifies the impact of human-induced climate change on the average wheat production and associated economic revenues in northern Kazakhstan in the 21st century and on the likelihood of a low-production year like 2010. The study uses bias-adjusted counterfactual and factual climate model data from two large ensembles of latest-generation climate models as input to a statistical subnational yield model. We consider the climate data and the yield model as fit for purpose as first, the factual climate simulations represent the observations, second, the out-of-sample validation of the yield model performs reasonably well with a mean R
2 of 0.54, and third, the results are robust under the performed sensitivity tests. Human-induced climate change has had a critical impact on wheat production, specifically through increases in daily-minimum temperatures and extreme heat. This has resulted in a decrease in yields during 2000–2019 by approximately 6.2%–8.2% (uncertainty range of two climate models) and an increased likelihood of the 2010 low-production event by 1.5–4.7 times (10th to 90th percentile uncertainty range covering both climate models). During 2000–2019, human-induced climate change caused economic losses estimated at between 96 and 180 million USD per year (10th to 90th percentile uncertainty range covering both climate models). These results highlight the necessity for ambitious global mitigation efforts and measures to adapt wheat production to increasing temperatures, ensuring regional and global food security.

Authors: Humphrey Hannah N , Sibley Pauline , Walker Eleanor T , Keller Deborah S , Pata Francesco , Vimalachandran Dale , Daniels Ian R , McDermott Frank D 
Published: June 2024

Abstract

Background
Diverticulosis is a normal anatomical variant of the colon present in more than 70% of the westernized population over the age of 80. Approximately 3% will develop diverticulitis in their lifetime. Many patients present emergently, suffer high morbidity rates and require substantial healthcare resources. Diverticulosis is the most common finding at colonoscopy and has the potential for causing a significant morbidity rate and burden on healthcare. There is a need to better understand the aetiology and pathogenesis of diverticular disease. Research suggests a genetic susceptibility of 40–50% in the formation of diverticular disease. The aim of this review is to present the hypothesized functional effects of the identified gene loci and environmental factors.

Methods
A systematic literature review was performed using PubMed, MEDLINE and Embase. Medical subject headings terms used were: ‘diverticular disease, diverticulosis, diverticulitis, genomics, genetics and epigenetics’. A review of grey literature identified environmental factors.

Results
Of 995 articles identified, 59 articles met the inclusion criteria. Age, obesity and smoking are strongly associated environmental risk factors. Intrinsic factors of the colonic wall are associated with the presence of diverticula. Genetic pathways of interest and environmental risk factors were identified. The COLQ, FAM155A, PHGR1, ARHGAP15, S100A10, and TNFSF15 genes are the strongest candidates for further research.

Conclusion
There is increasing evidence to support the role of genomics in the spectrum of diverticular disease. Genomic, epigenetic and omic research with demographic context will help improve the understanding and management of this complex disease.

Abstract

Aims
Abdominal aortic aneurysm (AAA) represents a life-threatening condition characterized by medial layer degeneration of the abdominal aorta. Nevertheless, knowledge regarding changes in regulators associated with aortic status remains incomplete. A thorough understanding of cell types and signalling pathways involved in the development and progression of AAAs is essential for the development of medical therapy.

Methods and results
We harvested specimens of the abdominal aorta with different pathological features in Angiotensin II (AngII)-infused ApoE−/− mice, conducted scRNA-seq, and identified a unique population of interferon-inducible monocytes/macrophages (IFNICs), which were amply found in the AAAs. Gene set variation analysis revealed that activation of the cytosolic DNA sensing cGAS-STING and JAK-STAT pathways promoted the secretion of type I interferons in monocytes/macrophages and differentiated them into IFNICs. We generated myeloid cell-specific deletion of Sting1 (Lyz2-Cre+/−; Sting1flox/flox) mice and performed bone marrow transplantation and found that myeloid cell-specific deletion of Sting1 or Ifnar1 significantly reduced the incidence of AAA, aortic rupture rate, and diameter of the abdominal aorta. Mechanistically, the activated pyroptosis- and inflammation-related signalling pathways, regulated by IRF7 in IFNICs, play critical roles in the developing AAAs.

Conclusion
IFNICs are a unique monocyte/macrophage subset implicated in the development of AAAs and aortic rupture.
A Comparative Study of Organizational Grief Support and Burnout Among Nursing Home Staff
Authors: Hawes Frances M , Wang Shuangshuang 
Published: June 2024

Abstract

Background and Objectives
The purpose of this study was to examine the relationship between dimensions of grief support (recognition of the relationship, acknowledgement of the loss, and inclusion of the griever) and aspects of burnout (emotional exhaustion, depersonalization, and personal accomplishment) among nursing home staff.

Research Design and Methods
Data were collected from 553 nursing home workers from 37 nursing home facilities in 5 states during fall of 2022. Responses to the Maslach Burnout Inventory and Grief Support Health Care Scale were analyzed for this study.

Results
The study found that recognizing the relationship with deceased patients led to a decrease in exhaustion and depersonalization among workers while simultaneously enhancing their sense of personal accomplishment. Including the griever in the support process lowered all burnout subscales for nursing home staff. Acknowledging the loss was associated with higher levels of personal accomplishment. Registered nurses, nurse practitioners, and physicians experienced higher levels of exhaustion and depersonalization compared to other nursing home staff. Behavioral health workers had the highest personal accomplishment, whereas direct support workers reported the lowest.

Discussion and Implications
These findings have important implications for improving the well-being of nursing home staff, emphasizing the importance of organizational grief support, and tailored interventions to address burnout among different healthcare provider roles in nursing homes.

Abstract
In recent years, potential therapeutic applications of several different cannabinoids, such as Δ9-tetrahydrocannabinol (Δ9-THC), its isomer Δ8-THC and Δ9-tetrahydrocannabivarin (Δ9-THCV), have been investigated. Nevertheless, to establish dose–effect relationship and to gain knowledge of their pharmacokinetics and metabolism, sensitive and specific analytical assays are needed to measure these compounds in patients. For this reason, we developed and validated an online extraction high-performance liquid/liquid chromatography–tandem mass spectrometry (LC/LC–MS-MS) method for the simultaneous quantification of 13 cannabinoids and metabolites including the Δ8 and Δ9 isomers of THC, THCV and those of their major metabolites in human plasma. Plasma was fortified with cannabinoids at varying concentrations within the working range of the respective compound and 200 µL was extracted using a simple one-step protein precipitation procedure. The extracts were analyzed using online trapping LC/LC–atmospheric pressure chemical ionization–MS-MS running in the positive multiple reaction monitoring mode. The lower limit of quantification ranged from 0.5 to 2.5 ng/mL, and the upper limit of quantification was 400 ng/mL for all analytes. Inter-day analytical accuracy and imprecision ranged from 82.9% to 109% and 4.3% to 20.3% (coefficient of variance), respectively. Of 534 plasma samples following controlled oral administration of Δ8-THCV, 236 were positive for Δ8-THCV (median; interquartile ranges: 3.5 ng/mL; 1.8–11.9 ng/mL), 383 for the major metabolite (−)-11-nor-9-carboxy-Δ8-tetrahydrocannabivarin (Δ8-THCV-COOH) (95.4 ng/mL; 20.7–328 ng/mL), 260 for (−)-11-nor-9-carboxy-Δ9-tetrahydrocannabivarin (Δ9-THCV-COOH) (5.8 ng/mL; 2.5–16.1 ng/mL), 157 for (−)-11-hydroxy-Δ8-tetrahydrocannabivarin (11-OH-Δ8-THCV) (1.7 ng/mL; 1.0–3.7 ng/mL), 49 for Δ8-THC-COOH (1.7 ng/mL; 1.4–2.3 ng/mL) and 42 for Δ9-THCV (1.3 ng/mL; 0.8–1.6 ng/mL). We developed and validated the first LC/LC–MS-MS assay for the specific quantification of Δ8-THC, Δ9-THC and THCV isomers and their respective metabolites in human plasma. Δ8-THCV-COOH, 11-hydroxy-Δ8-THCV and Δ9-THCV-COOH were the major Δ8-THCV metabolites in human plasma after oral administration of 98.6% pure Δ8-THCV.
