Abstract. Black carbon (BC) exerts potential effects on climate, especially in the Tibetan Plateau (TP), where the cryosphere and environment are very sensitive to climate change. The TP saw a record-breaking aerosol pollution event during the period from 20 April to 10 May 2016. This paper investigates the meteorological causes of the severe aerosol pollution event, the transboundary transport flux of BC, the aerosol–meteorology feedback, and its effect on the transboundary transport flux of BC during the severe aerosol pollution event using observational and reanalysis datasets as well as simulation based on a coupled meteorology and aerosol/chemistry model, Weather Research and Forecasting model coupled with Chemistry (WRF-Chem). By analyzing weather maps derived from the reanalysis dataset, it is found that the plateau vortex and southerly winds were key factors that contributed to the severe aerosol pollution event. Subsequently, due to the good performance of the WRF-Chem model for the spatiotemporal characteristics of meteorological conditions and aerosols, the transboundary transport flux of BC during the pollution event was investigated. The results show that the vertically integrated cross-Himalayan transport flux of BC decreases from west to east, with the largest transport flux of 20.8 mg m−2 s−1 occurring at the deepest mountain valley in southwestern TP. Results from simulations with and without aerosol–meteorology feedback show that aerosols induce significant changes in meteorological conditions in the southern TP and the Indo-Gangetic Plain (IGP), with the atmospheric stratification being more stable and the planetary boundary layer height decreasing in both regions, and the 10 m wind speed increasing in the southern TP but decreasing in the IGP. Changes in meteorological conditions in turn lead to a decrease in the surface BC concentration in the southern TP of up to 0.16 µg m−3 (50 %) and an increase in the surface BC concentration in the IGP of up to 2.2 µg m−3 (75 %). In addition, it is found that the aerosol–meteorology feedback decreases the vertically integrated transboundary transport flux of BC from the central and western Himalayas towards the TP. This study not only provides crucial policy implications for mitigating glacier melt caused by aerosols over the TP but is also of great significance for the protection of the ecological environment of the TP.

Abstract. Leaf area index (LAI) and fraction of photosynthetically active radiation (FPAR) are critical biophysical parameters for the characterization of terrestrial ecosystems. Long-term global LAI/FPAR products, such as the moderate resolution imaging spectroradiometer (MODIS) and the Visible Infrared Imaging Radiometer Suite (VIIRS), provide the fundamental dataset for accessing vegetation dynamics and studying climate change. However, existing global LAI/FPAR products suffer from several limitations, including spatial–temporal inconsistencies and accuracy issues. Considering these limitations, this study develops a sensor-independent (SI) LAI/FPAR climate data record (CDR) based on Terra-MODIS/Aqua-MODIS/VIIRS LAI/FPAR standard products. The SI LAI/FPAR CDR covers the period from 2000 to 2022, at spatial resolutions of 500 m/5 km/0.05∘, 8 d/bimonthly temporal frequencies and available in sinusoidal and WGS1984 projections. The methodology includes (i) comprehensive analyses of sensor-specific quality assessment variables to select high-quality retrievals, (ii) application of the spatial–temporal tensor (ST-tensor) completion model to extrapolate LAI and FPAR beyond areas with high-quality retrievals, (iii) generation of SI LAI/FPAR CDR in various projections and various spatial and temporal resolutions, and (iv) evaluation of the CDR by direct comparisons with ground data and indirectly through reproducing results of LAI/FPAR trends documented in the literature. This paper provides a comprehensive analysis of each step involved in the generation of the SI LAI/FPAR CDR, as well as evaluation of the ST-tensor completion model. Comparisons of SI LAI (FPAR) CDR with ground truth data suggest an RMSE of 0.84 LAI (0.15 FPAR) units with R2 of 0.72 (0.79), which outperform the standard Terra/Aqua/VIIRS LAI (FPAR) products. The SI LAI/FPAR CDR is characterized by a low time series stability (TSS) value, suggesting a more stable and less noisy dataset than sensor-dependent counterparts. Furthermore, the mean absolute error (MAE) of the CDR is also lower, suggesting that SI LAI/FPAR CDR is comparable in accuracy to high-quality retrievals. LAI/FPAR trend analyses based on the SI LAI/FPAR CDR agree with previous studies, which indirectly provides enhanced capabilities to utilize this CDR for studying vegetation dynamics and climate change. Overall, the integration of multiple satellite data sources and the use of advanced gap filling modeling techniques improve the accuracy of the SI LAI/FPAR CDR, ensuring the reliability of long-term vegetation studies, global carbon cycle modeling, and land policy development for informed decision-making and sustainable environmental management. The SI LAI/FPAR CDR is open access and available under a Creative Commons Attribution 4.0 License at https://doi.org/10.5281/zenodo.8076540 (Pu et al., 2023a).

Abstract – The phenomenon that is used as the object of research is the implementation of the special autonomy policy in Papua Province on increasing the Human Development Index (IPM) in Papua Province. The research objectives are (1) to analyze the implementation of the special autonomy policy in increasing HDI; (2) Analyze the obstacles to the implementation of the special autonomy policy in increasing the HDI; (3) Formulate a strategy for implementing special autonomy policies in increasing the HDI. Utilizing a qualitative approach, this study gathered data from four informants identified via the snowball technique, with additional information obtained from literature and direct observation. The collected data was then analyzed descriptively, refined through observer triangulation. This study explores the implementation of the special autonomy policy in Papua Province and its less than optimal impact on the Human Development Index (HDI). Key impediments include policy limitations in meeting stakeholders' interests, the types and extent of benefits conferred, change rate, decision-making, execution, and resource commitment. Further challenges arise from a weak anticipation of stakeholders' strengths, interests, strategies, institutional characteristics, compliance, and responsiveness. Given these constraints, current implementation has not effectively improved Papua's HDI as suggested by persistently low index scores. Obstacles to the implementation of the special autonomy policy in Papua Province on increasing HDI include structural constraints, cultural constraints and conditional constraints. The Special Autonomy ASOCA Strategy Model is a strategic approach derived from examining the special autonomy policy's impact on Papua Province's HDI

Published: January 2024

Acute ischemic stroke (AIS) is associated with high mortality, disability and economic expenses. Despite significant progress in the treatment of AIS using endovascular methods, it is not always possible to obtain good results. In the current literature, a small number of studies are devoted to predicting outcomes in patients with AIS who received various types of treatment.This prospective cohort study included 460 patients who underwent thrombolytic therapy, thromboextraction, combination of thromboextraction with stenting or thrombolytic therapy.The relationship between clinical and functional results at the early stages after intervention was assessed with potential predictors, among which the ultrasonic characteristics of extra- and intracranial arteries were analyzed.Complete or partial reperfusion was obtained in 61,7 % of the examined patients. A higher efficiency of endovascular methods compared to thrombolytic therapy was noted (99,5 % vs 33,5 % respectively). The baseline NIHSS and Rankin scores did not show a high predictive valuey for early outcomes, that caused the necessary for searching instrumental predictors. Patients with significant stenosis of the internal carotid artery or vertebral artery had significantly worse clinical and functional outcomes, including the mRS scale. The proportion of poor early outcomes in patients with significant stenosis was significantly lower in the endovascular treatment groups compared to the thrombolytic therapy group. Multiple regression analysis showed that the outcome of AIS is influenced by the level of cerebral arterial involvement as well as lesion size with a threshold value of more than 2 cm.

Reading Courtesy Texts in Late Medieval England: The Audience of Lydgate’s Stans puer ad mensam
Authors: Johnston Michael 
Published: January 2024

ABSTRACT
This article examines the reception of John Lydgate’s courtesy text Stans puer ad mensam, which survives in twenty-three manuscripts. Scholars of courtesy texts have tended to focus on the type of audience constructed by the text itself, but this article examines what the manuscript evidence tells us about actual readers. The manuscripts show that Lydgate’s poem appeared in numerous sorts of codicological environments, indicating that a broad range of reading environments was receptive to it. Based on close archival research, this article also surveys the provenance evidence, which shows that Lydgate’s attested readers belonged to the lower end of the late medieval English elite—primarily middling landowners and middling merchants. Such an audience maps nicely onto Stans puer’s scripting of behaviors for social advancement.
“Nobody Cain’t Die”: An Appalachian Analogue to the Old Man in Chaucer’s Pardoner’s Tale
Authors: Gulley Alison 
Published: January 2024

ABSTRACT
This article proposes a heretofore unidentified analogue to the old man in Chaucer’s Pardoner’s Tale. A similar figure appears as an old woman in the traditional Appalachian Jack Tale known as “Soldier Jack.” Dating to the fifteenth century in England, Jack Tales arrived in the United States sometime before 1800 and in Appalachia shortly thereafter. In “Soldier Jack,” Jack captures and keeps Death in a sack until he encounters an old woman who tells him that, because of his actions, no one has been able to die. In Chaucer’s tale, the old man, as a figure who cannot die, provides a similar warning about the folly of trying to control death.
Christ as Charioteer: An Expanded Image in Early Armenian Literature
Authors: Terian Abraham 
Published: January 2024

ABSTRACT
Beginning with the perception of God as warrior in the Hebrew Bible, the article explores the image of God as charioteer in a spectrum of theophanic texts, both biblical and parabiblical, underlying Jewish apocalyptic traditions translated into Christian beliefs surrounding the Cross as means of heavenly ascent. Equating the Cross with the tetramorphic chariot-throne of God in Ezekiel’s visions, an interpretive tradition mediated primarily through Syriac Christianity and rooted in the Christology of the New Testament, Armenian interpreters expanded the tradition. A close reading of early Armenian texts conveying the reception and transmission of the imagery of Christ as charioteer shows an expansion to a point of reordering the chariot’s heavenly ascent to earthly descent, a divine visitation to the land of Armenia, thus driving the tradition to a sort of realized eschatology.
Geographical Reality or Literary Fantasy: The Tainaron nekuomanteion as a Natural Deathscape
Authors: Gordon Joel Aaron 
Published: January 2024

ABSTRACT
This article redefines the dualism of nekuomanteia’s real and imagined topographies via a novel analysis of the tertium quid that is “natural deathscapes.” This framework is applied to the case study of the nekuomanteion at Tainaron. Comparison between the literary descriptions and the archaeological record reveals numerous anomalies within this landscape’s presentation, including an imaginary grove, spring, and impossible localizations. While traditional analyses explain away such matters as the result of poetic license or tradition, this approach cannot account for all identifiable inconsistencies. Thus, the site’s identification as a natural deathscape, a place associated with death / the dead and imbued with multifaceted sociocultural meanings, serves as a tertium quid that coalesces the site’s real and imagined topographies into a holistic landscape. Within this paradigm of spatial syncretism, particular attention is paid to the interaction of sociocultural functions inherent within the processes of landscape creation and eschatological reflection.
The Jeweled Castle of the Dragon
Authors: Ogden Daniel 
Published: January 2024

ABSTRACT
Five analog narratives—from Apuleius’s Metamorphoses (“Cupid and Psyche,” second century AD), Philostratus’s Apollonius (ca. AD 220), Callimachus and Chrysorrhoe (early fourteenth century AD), Konrad’s Saga (fourteenth century AD) and The Theodore Tiron Miracle Story (fourteenth century AD)—prove to be underpinned by an ideal story type along the following lines. A dragon lives in a golden, jeweled castle, almost impossible of access. It is surrounded by and infested by lesser serpents. Within it he has a special raised platform, and he is served in it by automatic air-powered trays, tables, and vessels. He conceives a desire for a human girl, steals her and keeps her captive. The castle is penetrated by her lover-to-be, who kills the dragon and saves her, whereupon the marvelous castle melts away. The theme of erotic desire travels with the story type. Further support is provided for the long-held suspicion that the Cupid and Psyche tale builds upon a preexisting traditional dragon narrative.

Introduction and objectiveOne of the main precursory lesions for pancreatic carcinoma is pancreatic cystic neoplasm. Differentiation between the various types of cysts is a clinical challenge. The microbiome colonizing the pancreatic cyst fluid is mostly unknown. The aim of the study was microbiological assessment of pancreatic cysts compared with biochemical parameters and histopathological results.Material and methods30 patients with pancreatic cysts undergoing surgery in 2022-2023 at the Department of General and Transplant Surgery, Medical University of Lodz, were enrolled in the study. Preoperative biochemical levels of blood parameters were analysed. Bacterial culture results were taken from the nasal vestibule, the skin of the groin, as well as from cyst fluid and bile (in case of cholecystectomy) and histopathological reports were analysed.ResultsMean age was 58.77±13.56 years. 10 patients (33.3%) had malignant lesions. Nine patients (30%) had positive cultures from cyst fluid. 6 of them had malignant conditions. <i>Enterobacter cloacae, Enterococcus faecium Staphylococcus spp.</i> were found. In the malignant group, patients were statistically significantly older (68.40±5.70 y vs. 53.95±13.86
y, p=0.004), tumour diameters were smaller (4.00±2.00 cm vs. 8.50±5.77 cm, p=0.003) and CA 19-9 level were higher (100.22±186.46 ng/ml vs. 12.35±16.08 ng/ml, p=0.045) than in a benign group.ConclusionsThe occurrence of specific types of bacteria in patients with malignant pancreatic cysts appears to be of significant clinical importance. Further studies are needed.
