Published: April 2024

Abstract. This article presents an enhanced emission module for the PALM model system, which collects discrete emission sources from different emission sectors and assigns them dynamically to the prognostic equations for specific pollutant species as volumetric source terms. Bidirectional lookup between each source location and cell index are maintained through using a hash key approach, while allowing all emission source modules to be conceived, developed and operated in a homogeneous and mutually independent manner. An additional generic emission mode has also been implemented to allow the use of external emission data in simulation runs. Results from benchmark runs indicate a high level of performance and scalability. Subsequently, a module for modelling parametrized emissions from domestic heating is implemented under this framework, using the approach of building energy usage and temperature deficit as a generalized form of heating degree days. An model run has been executed under idealized conditions by considering solely dispersion of PM10 from domestic heating sources. The results demonstrate a strong overall dependence on the strength and clustering of individual sources, diurnal variation in domestic heat usage, as well as the temperature deficit between the ambient and the user-defined target temperature. Vertical transport contributes additionally to a rapid attenuation of daytime PM10. Although urban topology plays a minor role on the pollutant concentrations at ground level, it has a relevant contribution to the vertical pollutant distribution.
Application of machine learning to forecast agricultural drought impacts for large scale sub-seasonal drought monitoring in Brazil

Published: April 2024

Abstract. Drought events have increased in frequency and severity in recent years, and result in significant economic losses. Although the Brazilian semi-arid northeast has been historically associated with the impacts of drought, drought is of national concern, from 2011–2019, drought events were recorded in all Brazilian territories. Droughts can have major consequences for agricultural production, which is of particular concern given the importance of soybeans for socio-economic development. Due to its regional heterogeneity, it is important to develop accurate drought forecast and assessment tools for Brazil. We explore machine learning as a method to forecast the vegetation health index (VHI), for large scale monthly drought monitoring across agricultural land in Brazil. Furthermore, we also determine spatio-temporal drivers of VHI across the wide variation in climates, as well as evaluate machine learning performance for ENSO variation, forecasting of the onset of drought impact, and how the trade off between spatial variation and sample size affects model performance. We show that machine learning methods such as gradient boosting methods are able to more easily forecast vegetation health in the north and north east Brazil than south Brazil, and perform better during La Niña events than El Niño events. Drought impacts which reduce VHI below the commonly used 40 % threshold can be forecast across Brazil with similar model performance. SPEI is shown to be a useful indicator of drought impact, with 3 month accumulation periods preferred over 1 and 2 months. Results aim to inform future developments in operational drought monitoring at the National Center for Monitoring and Early Warning of Natural Disasters in Brazil (CEMADEN). Future work should build upon methods discussed here to improve drought forecasts for agricultural drought response and adaptation.
A satellite view of the exceptionally warm summer of 2022 over Europe

Published: April 2024

Abstract. Summer heatwaves are becoming increasingly dangerous over Europe, and their close monitoring is essential for human activities. Typically, they are monitored using the 2 m temperature from meteorological weather stations or reanalysis datasets. In this study, the 2022 extremely warm summer over Europe is analysed using satellite land surface temperature (LST), specifically the LSA SAF (Land Surface Analysis Satellite Application Facility) all-sky LST product (available from 2004 onwards). Since climate applications of LST are still poorly explored, heatwave diagnostics derived from satellite observations are compared with those derived using ERA5/ERA5-Land reanalysis data. Results highlight the exceptionality of 2022 in different metrics such as the mean LST anomaly, area under extreme heat conditions, number of hot days and heatwave magnitude index. In all metrics, 2022 ranked first when compared with the remaining years. Compared to 2018 (next in all rankings), 2022 exceeded its LST anomaly by 0.7 °C and each pixel had on average 7 more hot days. Satellite LST complements reanalysis diagnostics, as higher LST anomalies occur over areas under severe drought, indicating a higher control and amplification of the heatwave by surface processes and vegetation stress. These cross-cutting diagnostics increase the confidence across satellite data records and reanalyses, fostering their usage in climate applications.

Published: April 2024

Abstract. While thermochronological studies have constrained the landscape evolution of several of the crustal blocks of West and East Antarctica, the tectono-thermal evolution of the Ellsworth Mountains remains relatively poorly constrained. These mountains are among the crustal blocks that comprise West Antarctica and exhibit an exceptionally well-preserved Palaeozoic sedimentary sequence. Despite the seminal contribution of Fitzgerald and Stump (1991), who suggested an Early Cretaceous uplift event for the Ellsworth Mountains, further thermochronological studies are required to improve the current understanding of the landscape evolution of this mountain chain. We present new zircon (U–Th) / He (ZHe) ages, which provide insights into the landscape evolution of the Ellsworth Mountains. The ZHe ages collected from near the base and the top of the sequence suggest that these rocks underwent burial reheating after deposition. A cooling event is recorded during the Jurassic–Early Cretaceous, which we interpret as representing exhumation in response to rock uplift of the Ellsworth Mountains. Moreover, our results show that while ZHe ages at the base of the sequence are fully reset, towards the top ZHe ages are partially reset. Uplift and exhumation of the Ellsworth Mountains during the Jurassic–Early Cretaceous was contemporaneous with the rotation and translation of this crustal block with respect to East Antarctica and possibly the Antarctic Peninsula. Furthermore, this period is characterized by widespread extension associated with the disassembly and breakup of Gondwana, with the Ellsworth Mountains playing a key role in the opening of the far southern Atlantic. Based on these results, we suggest that uplift of the Ellsworth Mountains during the disassembly of Gondwana provides additional evidence for major rearrangement of the crustal blocks between the South American, African, Australian and Antarctic plates. Finally, uplift of the Ellsworth Mountains commenced during the Jurassic, which predates the Early Cretaceous uplift of the Transantarctic Mountains. We suggest that the rift-related exhumation of the Ellsworth Mountains occurred throughout two events: (i) a Jurassic uplift associated with the disassembly of southwestern Gondwana and (ii) an Early Cretaceous uplift related with the separation between Antarctica and Australia, which is also recorded in the Transantarctic Mountains.
Towards the systematic reconnaissance of seismic signals from glaciers and ice sheets – Part 1: Event detection for cryoseismology
Authors: Latto Rebecca B. , Turner Ross J. , Reading Anya M. , Winberry J. Paul
Published: April 2024

Abstract. Cryoseismology is a powerful toolset for progressing the understanding of the structure and dynamics of glaciers and ice sheets. It can enable the detection of hidden processes such as brittle fracture, basal sliding, transient hydrological processes, and calving. Addressing the challenge of detecting signals from many different processes, we present a novel approach for the semi-automated detection of events and event-like noise, which is well-suited for use as Part 1 of a workflow where unsupervised machine learning will be used as Part 2 (Latto et al., 2024) to facilitate the main reconnaissance of diverse detected event types. Implemented in the open-source and widely used ObsPy Python package, the multi-STA/LTA algorithm constructs a hybrid characteristic function from a set of short-term average (sta)–long-term average (lta) pairs (refer to Sect. 2 in the main text for an explanation of how uppercase and lowercase STA/sta and LTA/lta abbreviations are differentiated). We apply the algorithm to data from a seismic array deployed on the Whillans Ice Stream (WIS) in West Antarctica (austral summer 2010–2011) to form a “catch-all” catalogue of events and event-like noise. The new algorithm compares favorably with standard approaches, yielding a diversity of seismic events, including all previously identified stick-slip events (Pratt et al., 2014), teleseisms, and other noise-type signals. In terms of a catalogue overview, we investigate a partial association of seismicity with the tidal cycle and a slight association with ice temperature changes of the Antarctic summer. The new algorithm and workflow will assist in the comparison of different glacier environments using seismology, the identification of process change over time, and the targeting of possible subsequent high-resolution studies.

Published: April 2024

Abstract. Given the high number and diversity of events in a typical cryoseismic dataset, in particular those recorded on ice sheet margins, it is desirable to use a semi-automated method of grouping similar events for reconnaissance and ongoing analysis. We present a workflow for employing semi-unsupervised cluster analysis to inform investigations of the processes occurring in glaciers and ice sheets. In this demonstration study, we make use of a seismic event catalogue previously compiled for the Whillans Ice Stream, for the 2010–2011 austral summer (outlined in Part 1, Latto et al., 2024). We address the challenges of seismic event analysis for a complex wave field by clustering similar seismic events into groups using characteristic temporal, spectral, and polarization attributes of seismic time series with the k-means++ algorithm. This provides the basis for a reconnaissance analysis of a seismic wave field that contains local events (from the ice stream) set in an ambient wave field that itself contains a diversity of signals (mostly from the Ross Ice Shelf). As one result, we find that two clusters include stick-slip events that diverge in terms of length and initiation locality (i.e., central sticky spot and/or the grounding line). We also identify a swarm of high-frequency signals on 16–17 January 2011 that are potentially associated with a surface melt event from the Ross Ice Shelf. Used together with the event detection presented in Part 1, the semi-automated workflow could readily be generalized to other locations and, as a possible benchmark procedure, could enable the monitoring of remote glaciers over time and comparisons between locations.
WCD Ideas: Teleconnections through weather rather than stationary waves
Authors: Spensberger Clemens
Published: April 2024

Abstract. Conventionally, teleconnections in the atmosphere are described by correlations between monthly mean fields. These correlations are supposedly caused by stationary Rossby waves. The main hypothesis explored in this idea is that teleconnections are instead established by chains of events on synoptic timescales, that is by weather. Instead I hypothesise that non-stationary Rossby waves play an important role in establishing teleconnections. If these hypotheses are correct, much of the vast literature on this topic misses an essential part of the atmospheric dynamics leading to teleconnections.

Does Environmental Court Lead to Local Green Growth? Evidence from 230 Cities in China
Authors: Xin Ge , Wang Feng
Published: April 2024

To tackle the multifaceted environmental challenges and bolster environmental law enforcement in China, environmental courts have proliferated across many cities since 2007. However, their actual effects on economic growth, a central concern for governments at all levels, have yet to be thoroughly investigated. Leveraging the panel data of 230 cities from 2007-2016 and taking the establishment of environment courts as a quasi-natural experiment, this paper uses the difference-in-differences (DID) approach to examine the effects of building environmental courts on green economic growth at the prefectural level. We find that first, the effect is positive and significant; second, on possible channel for the boosting effect of environment court is through increasing technological innovation; third, the effect of court on green growth is more significant after two to three years. These findings provide references for both scholars of environmental politics and practitioners of green development in local governments.
RITME EDITING DALAM KONVENSI GENRE DAN MOOD FILM: STUDI KASUS FILM KKN DI DESA PENARI DAN WANALATHI
Authors: Prama Saputra Ary
Published: April 2024

Untuk bisa mengetahui keberadaan ritme editing sebuah film sangatlah mudah. Kita cukup dengan sadar menyimak pergantian gambar yang terjadi akibat cutting. Selanjutnya kita akan menyimpulkan tentang irama serta tempo film sebagai cepat atau lambat dimana kemudian disebut sebagai pace, berdasarkan sebuah pola. Tapi apakah ritme dan pace film hanya terbentuk melalui apa yang disebutkan sebelumnya? Juga apakah ritme editing keberadaannya hanya untuk sekedar membuat irama tanpa arah dan fungsi? Jawabannya adalah tidak. Keberadaan ritme editing film tidak boleh seperti itu karena dia harus bersinergi dengan naratif filmya. Jadi jika naratif memiliki elemen yang ditata maka ritme editing filmnya juga harus mengusahakan tatanan dari faktor ritmenya mejadi bentuk yang tepat. Karena arahan bentuk ritme yang salah dari editing akan fatal dampaknya bagi film. Respon negatif bisa bermunculan mengenai film yang membosankan karena terasa lambat atau bikin pusing karena terlalu cepat ritmenya. Lalu bagaimana cara mengetahui bahwa ritme yang dibentuk melalui editing sudah tepat? Apalagi jika tatanan elemen naratif film mengarah ke genre tertentu yang pasti mengerucut jadi sebuah konvensi. Tentu cepat atau lambatnya film, baik di adegan tertentu juga keseluruhan film akan memperhatikan beberapa hal terlebih dahulu sebelum dibentuk. Tulisan ini berusaha mengetahui apakah faktor ritme film yang diolah dalam sebuah film memiliki bentuk yang tepat sehingga mendukung bertemunya konvensi dengan harapan atau mood yang ingin dimunculkan dari sebuah film. Cara yang dilakukan adalah mengurai perihal ritme editing yang terjadi dibatasan durasi yang sama dari dua film yang berbeda, yaitu film horor.

Measuring Regional Competitiveness: New Insights Based on the RCI
Authors: Maza Adolfo , Hierro Maria
Published: April 2024

The design of a comprehensive measure of regional competitiveness has attracted much attention, with the Regional Competitiveness Index (RCI) as a benchmark. We contribute from two different perspectives. On the one hand, we test the robustness of the RCI results by modifying the dimensionality reduction technique. On the other hand, we explore the importance of two factors in the analysis of regional competitiveness: geographical distance to potential competitors (by correcting the index with the introduction of several distance measures) and technological specialization (by making a prior selection of the regions that are expected to compete mostly either in high-tech sectors or in medium- or low-tech sectors, and recalculating the index accordingly). The results show that the RCI indicator is robust to the variable reduction methods employed. Moreover, including geographical distance substantially modifies the degree of competitiveness of many regions, which we believe cannot be neglected since competition tends to be fiercer the shorter the distance between the regions involved. Finally, if regions are categorized into two groups based on their technology level, some changes in RCI rankings are very noticeable.

To evaluate the in vitro and in vivo pharmacological efficacy of the plant Chlorophytum borivilianum in diabetes and hyperlipidemia and to confine and describe the synthetic constituents from the roots that are in charge of the action. The present study was carried out to investigate the ethno-medical use of Chlorophytum borivilianum root methanolic extract as a potential anti-diabetic and antihyperlipidemic agent in STZ-induced diabetic rats. Extract was tested for in vitro and in vivo biological activities. Soxhlet extraction was carried out using methanol as a solvent, and TLC and column chromatography were used for fractionation. Liquid Chromatography and Mass Spectroscopic study confirmed the structures of isolated compounds. Chlorophytum borivilianum root methanolic extract showed the presence of phytoconstituents as Dihydrocapsaicin, Reserpine, Deserpidine, Biliverdin-IX-α, and Cassiamin C having a therapeutic effect. Dihydrocapsaicin was identified at RT 7.572 and the Chlorophytum borivilianum root chloroform methanolic extract fraction noticeably depleted increased blood glucose levels and had positive effects on altered lipid profile after administering a dose of 150 mg/kg orally compared with oral hypoglycemic drug metformin. All the results are dose-dependent. Active chloroform-methanol fraction from methanol extract showed the presence of anti-diabetic compound, Dihydrocapsaicin. The chloroform-methanol fraction from the methanolic extract of Chlorophytum borivilianum root can inhibit the parameters linked to diabetes and hyperlipidemia.

In modern manufacturing, due to the narrow format, short size, and complex surface structure of small-sized workpieces, automatic detection of surface defects, dimensions, etc. on small-sized workpieces faces difficulties, making it difficult to meet the requirements of fully automated production lines. Especially, there is no good solution to the problem of high-precision automatic measurement of geometric features of circles and arcs on small-sized workpieces. This article takes the engine end cover circular hole thermal component as the research object, builds a hardware platform for image acquisition of small-sized workpieces based on machine vision, proposes an online size measurement method for small-sized circular holes, and realizes the measurement of the position size and aperture size of small-sized product shell workpieces. In order to achieve the above methods, this article builds a visual detection hardware system and describes a detailed machine vision hardware selection scheme. Then, the images collected by the system are preprocessed, including image denoising, image correction, and image feature extraction. Then, for the processed images, an improved Hough transform fitting method is used to obtain the online size of features. In order to visualize the results, the detection system and software are designed according to the actual application scenario. The overall scheme of this article is efficient and reasonable, and the detection result error is within a reasonable range.

A highlight model for the target signal in the bistatic system is proposed based on the calculation results of the acoustic field, which means that the target can be equivalent to several highlights according to certain characteristics of the target when calculating the scattering acoustic field. The parameters of the highlight model were given based on the calculation results. Two sets of experiments on the highlight model of the bistatic system were conducted with a fixed transmitter and a target, one being the receiver rotating around the target, and the other being the target rotating around itself at different receiver angles. The comparison of multi angle pseudo color images through experiments and theoretical simulations shows that the scattering highlight model can describe the scattering characteristics of the target to a certain extent. Only geometric highlights were simulated in this article, and it can be foreseen that bistatic system highlight model of scattering waves can be accurately described with a full understanding of the target.

Geospatial knowledge in massive academic papers can provide knowledge services such as location-based research hotspot analysis, spatio-temporal data aggregation, research results recommendation, etc. However, geospatial knowledge often exists implicitly in literature resources in unstructured form, which is difficult to be directly accessed and mined and utilized for rapid production of massive thematic maps. In this paper, we take the geospatial knowledge of the area studied as an example and introduce its extraction method in detail. An integrated feature template matching and random forest classification algorithm is proposed for accurately identifying research areas from the abstract texts of academic papers and producing thematic maps. Firstly, the precise recognition of geographical names is achieved step by step based on BiLSTM-CRF algorithm and improved heuristic disambiguation method; then, the area studied is extracted by the designed integrated feature recognition template of area studied using random forest classification algorithm, and a fast thematic map is designed for the knowledge of area studied, topic and literature. The experimental results show that the area studied recognition accuracy can reach 97%, the F-value is 96%, and the recall rate reaches 96%, achieving high accuracy and high efficiency of area studied extraction in text. Based on the geospatial knowledge, the thematic map can achieve the effect of fast map formation and accurate expression.

The Position of Revelation in the Clamp of Deism and Shirk
Authors: İpek Mikail
Published: April 2024

Deists do not accept the idea of God's intervention in the world, but they argue that reason has infinite authority. Those who adopt the idea of deism adopt the idea that God did not intervene in the world after the first creation. Since revelation, religion, and prophethood are regarded as God's intervention in the world, prophethood in particular is considered impossible in terms of its possibility and necessity. It is known that there is an Indian belief group called Berāhime, which adopts ideas in the same vein as the idea of deism. The followers of this belief objected to the idea of prophethood from a rational point of view. According to them, if there was such a thing as prophethood, God would have created this idea in the minds. In addition, according to the Berāhime, reason and revelation are in contradiction, and worship is absurd and meaningless. On the other hand, there is no aspect of the concept of the miracle that looks at the truth. When we look at the specific characteristics of these two schools, it is understood that both of them are fed from the same source. The human model that these and similar schools of thought want to build desires a lifestyle that has nothing to do with worship and in which God does not control and question them. This lifestyle undoubtedly brings to mind the pre-Islamic "Jahiliyya Period" understanding of shirk. Because the polytheists also believed in the existence of Allah and recognized Him as a holy and supreme Creator. The fact that a community that believes in Allah rejects or objects to institutions such as prophets and revelation is important in terms of the subject under consideration. The polytheists, while believing in God, wished that God would not interfere with them, especially in matters such as worship. This shows that the polytheists adopted a deistic lifestyle whether they realized it or not. In our opinion, there is a parallelism between the idea of Deism and the idea of shirk. The dangers of the idea of Deism, which attracts the attention of some people today, reveal the importance of the subject. The aim of this study is to show that Deism and Berāhimah serve similar purposes and ultimately encourage people to live a largely worldly life of shirk.
golpe de abril de 1964 e porque as datas importam

Published: April 2024

Problematizando sobre a relevância política das datas históricas, este artigo retoma o dilema sobre qual é o exato dia do golpe de Estado de 1964: 31 de março ou 1° de abril? Defende que apesar do movimento militar golpista ter se iniciado na manhã do dia 31 de março, foi apenas no dia 1° de abril que o êxito do golpe se confirmou. Até o dia 1°, havia condições de resistência que, por vários motivos, foram desperdiçadas pelo governo federal e seus apoiadores.
