The interplay between blockchain and big data analytics for enhancing supply chain value creation in micro, small, and medium enterprises
Authors: Jabbar Abdul , Akhtar Pervaiz , Ali Syed Imran 
Published: December 2024

AbstractThis study explores the interplay between blockchain-based smart contracts and big data analytics for the supply chain value creation of micro, small, and medium enterprises (MSMEs). We implement our Ethereum Virtual Machine (EVM) procedure with the ganache blockchain, and addresses generated by the Metamask wallet. Each supply chain player in the blockchain is assigned a wallet address to observe the hashes created when data is added to the blockchain. Our findings unfold that supply chain value creation emphasises traceability, transparency, security, and profit maximisation interlocked with how effectively companies utilise big data collected through blockchain-based smart contracts. This subsequentially assists managers in using data types and a variety of analytics, spanning from descriptive, diagnostic, predictive, and prescriptive to cognitive analytics. This synergy between the blockchain and the types of analytics provides opportunities to identify new interactions and directions for future research.

Abstract
This paper provides insights into the radioactivity levels in soils and marine sediments from selected monitoring sites in Singapore. The environmental samples were measured for naturally occurring (e.g., 40K, 238U, 235U, 234U and 232Th) and anthropogenic (e.g., 90Sr, 137Cs, 239Pu and 240Pu) radionuclides. Additionally, the 137Cs activity in surface seawater was analysed. In soil, the decay series of 232Th and 238U are the highest contributors to the total radioactivity, while in sediments, 40K is the main contributor to the total radioactivity. The massic activities of anthropogenic radionuclides in soil (90Sr: 0.24–0.34 Bq kg−1; 137Cs: < 0.3–0.65 Bq kg−1; 239+240Pu: 0.002–0.057 Bq kg−1) and sediment (90Sr: 0.15–0.17 Bq kg−1; 137Cs: < 0.46–0.54 Bq kg−1; 239+240Pu: 0.239–0.294 Bq kg−1), and the activity concentration of 137Cs in seawater (137Cs: 1.1 mBq kg−1), are low and comparable to the values reported for the region. The Pu isotope data demonstrates that the main source of anthropogenic radionuclides in soil (240Pu/239Pu atom ratios: 0.17–0.19) is the global fallout from nuclear weapons testings (NWTs); in sediments (240Pu/239Pu atom ratios: 0.24–0.26), contributions from the Pacific Proving Grounds (PPG) have also been identified. This study also highlights significant differences in radioactivity levels in soils between the northern and central regions of Singapore, which are attributed to soil disturbances in the northern region as a result of intensive anthropogenic activities carried out in the 1980s.
The power of empirical evidence: assessing changes in public opinion on constitutional emergency provisions
Authors: Iwasaki Masaki 
Published: December 2024

Abstract
The Japanese government is attempting to put emergency clauses in the Constitution. Although the overwhelming majority of legal scholars and practitioners vehemently oppose the initiative, public opinion polls indicate a close divide between opponents and supporters. This division may partly stem from the difficulty the public faces in reaching a conclusive decision through abstract legal arguments. Recently, an empirical study analyzing emergency clauses in various countries showed that such clauses tend to increase government violations of human rights and the death toll during disasters. Our survey experiment investigates how presenting such empirical evidence—which corroborates opponents’ legal arguments—as a treatment affects public support for the potential Japanese emergency clauses. We find that the treatment shifts the ratio of opposition to support from roughly 1:1 to 2.6:1. In the placebo group, the proportions of opposition, neutrality, and support are 28.8%, 43.2%, and 28.0%, compared to 47.7%, 33.6%, and 18.7% in the treatment group. Additionally, initial supporters of the clauses shift more toward opposition after the intervention than do opponents or neutrals. These results suggest that should a referendum be held, making the public aware of the empirical analysis could markedly influence the outcome.
Self-Adjointness, Dynamics of Solutions and Conserved Currents of a Multi-Dimensional Nonlinear Fifth-Order Generalized ZK Equation with Dual Power-Laws in an Electron–Positron–Ion Magnetoplasma with Various Life Applications
Authors: Adeyemo Oke Davies 
Published: December 2024

Abstract
Electron–positron–ion plasmas emerge in active galactic nuclei, the primordial Universe, peripheries of neutron stars, and surroundings of black holes. Thus, this article showcases the analytical examination of a multi-dimensional fifth-order generalized Zakharov–Kuznetsov model with dual power-law nonlinearities in an electron–positron–ion magnetoplasma. This interesting electron–positron–ion plasma model, with enough nonlinear mathematics and astrophysics/cosmology considerations, is observed to possess various copious real-world scenarios, especially in cosmic plasmas. In essence, a thorough investigation of the model is carried out with a view to see the application of its results in various science and engineering disciplines. Abundant soliton solutions to the models are to be generated, and various wave structures of interest are to be simulated numerically. In the wake of the robust Lie group theory, a comprehensive Lie group analysis of this equation with power-law nonlinearities is further performed. This consequently leads to the emergence of diverse invariants and solutions associated with the model. In addition, the equation is reduced to diverse ordinary differential equations using its point symmetries, and consequently, diverse closed-form solutions of interest are achieved for some particular cases of n. These outcomes are obtained in the form of complex and non-complex dark solitons, topological solitons, as well as various algebraic solutions with arbitrary functions. Moreover, by utilizing the power series method, one derives some series solutions of the understudy models for some specific cases of some of the consequential difficult nonlinear ordinary differential equations. A deep understanding of the found solutions is aided by simulating some of the solutions. Consequently, various soliton collisions ensued, thus giving rise to diverse structures of psychedelic bump waves, parabolic waves, concentric wave shapes with strata, as well as other wave forms of interest which are discussed. The real-world applications of the various achieved wave dynamics are presented in detail to bring the pertinence of the research results home. Thereafter, strict self-adjointness as well as formal Lagrangian formulation, leading to various conservation laws via Ibragimov’s theorem, are entrenched. Consequently, conservation of energy, momentum, and angular momentum is achieved, which has a very wide spectrum of pertinence and significance, especially in the fields of physics and mathematics.

AbstractThe Messel Pit is a Konservat-Lagerstätte in Germany, representing the deposits of a latest early to earliest middle Eocene maar lake, and one of the first palaeontological sites to be included on the list of UNESCO World Heritage Sites. One aspect of Messel that makes it so extraordinary is that its sediments are rich in different fossilised organisms – microfossils, plants, fungi, invertebrate animals and vertebrates – that are rarely preserved together. We present an updated list of all taxa, named or not, that have been documented at Messel, comprising 1409 taxa, which represent a smaller but inexactly known number of biological species. The taxonomic list of Labandeira and Dunne (2014) contains serious deficiencies and should not be used uncritically. Furthermore, we compiled specimen lists of all Messel amphibians, reptiles and mammals known to us. In all, our analyses incorporate data from 32 public collections and some 20 private collections. We apply modern biodiversity-theoretic techniques to ascertain how species richness tracks sampling, to estimate what is the minimum asymptotic species richness, and to project how long it will take to sample a given proportion of that minimum richness. Plant and insect diversity is currently less well investigated than vertebrate diversity. Completeness of sampling in aquatic and semiaquatic, followed by volant, vertebrates is higher than in terrestrial vertebrates. Current excavation rates are one-half to two-thirds lower than in the recent past, leading to much higher estimates of the future excavation effort required to sample species richness more completely, should these rates be maintained. Species richness at Messel, which represents a lake within a paratropical forest near the end of the Early Eocene Climate Optimum, was generally higher than in comparable parts of Central Europe today but lower than in present-day Neotropical biotopes. There is no evidence that the Eocene Messel ecosystem was a “tropical rainforest.”
Rewilding’s social–ecological aims: Integrating coexistence into a rewilding continuum
Authors: Hawkins Sally , Carver Steve , Convery Ian 
Published: December 2024

AbstractThis paper presents results from a grounded theory study of rewilding aims, addressing calls for broad scale studies of rewilding to contribute to the development of guidelines. The grounded theory draws from a broad set of data sourced from rewilding organizations, case studies, and research. Expressions from the data relating to rewilding aims and outcomes were coded. The results demonstrate the intentions for rewilding to affect systemic, ecological, and socio-cultural change. Outcomes to support rewilding aims are also identified. The aims and outcomes are presented under these headings in a social–ecological framework which offers a shared vision for rewilding. The significance of this research is that it demonstrates rewilding’s multi-disciplinarity and engagement with systemic or transformative change. It addresses a perceived paradox between rewilding intervention and non-human autonomy, demonstrating that rewilding is not necessarily about removing human influence but affecting coexistence through more-than-human collaboration. A revised rewilding continuum integrating coexistence is proposed.

Abstract
Background
Studies on renal vein thrombosis have been conducted as case reports or case series. The renal outcomes and mortality risk of renal vein thrombosis have not been fully established. We aimed to investigate the clinical characteristics, treatment modalities, and predictors of renal outcomes and mortality in patients with renal vein thrombosis in a large multicenter cohort.

Methods
We retrospectively assessed 182 patients with renal vein thrombosis diagnosed between January 2011 and May 2023 using either Doppler ultrasonography or computed tomography venography. The main outcomes analyzed were all-cause mortality, and worsening kidney function.

Results
We evaluated 182 patients comprising 76 males (41.8%) and 106 females (58.2%). Nephrotic syndrome was the most common cause (51.6%) followed by malignancy (33%) and post-trauma or surgery (11%). Kidney function worsened in 126 patients (69.2%). Acute kidney injury (AKI) was identified in 72 patients (39.6%), whereas 54 patients (29.7%) developed chronic kidney disease (CKD). Multivariate logistic regression showed that declining kidney function was reliably predicted by nephrotic syndrome (Odds ratio (OR): 6.41, P = 0.004), serum albumin (OR: 0.31, P = 0.003), and diabetes mellitus (OR: 14.04, P < 0.001). Eighty-two patients (45.1%) died while being monitored. Sepsis accounted for the majority of deaths (25.3%). Bilateral renal vein thrombosis (Hazard Ratio (HR): 5.61, P < 0.001), malignancy (HR: 6.15, P = 0.004), serum albumin (HR: 0.12, P < 0.001), hemoglobin (Hb) level (HR: 0.102, P < 0.001) and diabetes mellitus (HR: 2.42, P = 0.007) were all reliable predictors of all-cause mortality using multivariate Cox regression.

Conclusion
Renal vein thrombosis is associated with a higher risk of mortality and worsening kidney function. It is essential to promptly identify high risk patients and start early treatment to prevent unfavorable outcomes.

Classification of Automotive Aluminum Scrap into Cast and Wrought Alloys via Particle Size Analysis
Authors: Shankar Shrivatsav , Söderhjelm Carl , Apelian Diran 
Published: December 2024

AbstractThe Aluminum (Al) industry is currently faced with the challenge of significantly reducing the environmental impact of Al production. Secondary Al or Al produced from Al scrap offers a beneficial pathway to lowering the production carbon footprint and energy consumption while transitioning to a circular economy business model. However, mixing of Al scrap streams and introduction of impurity elements at end of life lead to “downcycling” of Al alloys. Downcycling of Al alloys has been the norm in the automotive recycling industry. Automotive Al scrap from auto shredders dubbed “Twitch,” is an amalgamation of different Al alloys, cast as well as wrought alloys. Twitch is traditionally downcycled to low-value Al alloys due to the complexities in separating the Twitch into various alloy families as well as difficulties in blending and producing high-value Al alloys from scrap. This paper provides a framework and an approach that uses size gating, mass, and image analysis to separate the wrought and cast alloys within the Twitch feedstock and provides a simpler and a cost-effective means of separation of the scrap stream.

Abstract
In recent years, conventional chemistry techniques have faced significant challenges due to their inherent limitations, struggling to cope with the increasing complexity of and volume of data generated in contemporary research endeavors. Computational methodologies represent robust tools in the field of chemistry, offering the capacity to harness potent machine learning (ML) models to yield insightful analytical outcomes. This review examines the integration of machine learning into natural product chemistry from 2015 to 2023, highlighting its potential to overcome the inherent limitations of traditional chemical techniques. We present a structured approach that matches specific natural product challenges—such as component determination, concentration prediction, and classification—with suitable ML models, including regression, classification, and dimension reduction methods. Our objective is to illustrate how ML pipelines, from data preprocessing to model evaluation, enhance both qualitative and quantitative analyses, providing a comprehensive framework, with the potential catalyze a transformation in the field of natural product analysis.
Bragg scattering of surface-gravity waves by an ice shelf with rolling surface morphology
Authors: Konovalov Yuri V. 
Published: December 2024

Abstract
The propagation of elastic-flexural–gravity waves through an ice shelf is modeled using full three-dimensional elastic models that are coupled with a treatment of under-shelf sea-water flux: (i) finite-difference model (Model 1), (ii) finite-volume model (Model 2) and (iii) depth-integrated finite-difference model (Model 3). The sea-water flow under the ice shelf is described by a wave equation involving the pressure (the sea-water flow is treated as a “potential flow”). Numerical experiments were undertaken for an ice shelf with ‘rolling’ surface morphology, which implies a periodic structure of the ice shelf. The propagation of ocean waves through an ice shelf with rolling surface morphology is accompanied by Bragg scattering (also called Floquet band insulation). The numerical experiments reveal that band gaps resulting from this scattering occur in the dispersion spectra in frequency bands that are consistent with the Bragg’s law. Band gaps render the medium opaque to wave, that is, essentially, the abatement of the incident ocean wave by ice shelf with rolling surface morphology is observed in the models. This abatement explains the ability of preserving of ice shelves like the Ward Hunt Ice Shelf, Ellesmere Island, Canadian Arctic, from the possible resonant-like destroying impact of ocean swell.
From Biblical Semantics to Theology: Divine and Human כעס and קנאה
Authors: Seri-Levi Ariel 
Published: December 2024

AbstractScholarship assumes no significant differences among various “terms for anger” in the Hebrew Bible, but it does assume an essential difference between human and divine anger. This article challenges these preconceptions by presenting a novel semantic analysis of כעס, considered a “term for anger.” It shows that in Classical Biblical Hebrew, כעס does not denote anger but rather sorrow or insult associated with קנאה, “jealousy.” This analysis leads to a new, deeper, and more precise understanding of the phrase “to cause כעס to Yhwh” and of its meaning in biblical literature and theology in general and in Deuteronomistic writings in particular.
From The Creators of Knowledge to the Specialists of Spirit: Anti-Clericalism in Iran’s Modernist Intellectual Discourse (1925–1941)
Authors: Zarrinnal Navid 
Published: December 2024

AbstractIn the early twentieth century, the Iranian Reza Shah state (1925–1941), in conjunction with the emerging group of state-trained scholars, called the status of ulama as knowledge producers into question. Existing scholarship has primarily examined the impact of state modernization on the Muslim clergy and their responses to modernization but has paid lesser attention to the passive role of the ulama or their representation in modernist intellectual and literary discourses. I examine two major Persian sources of the period to argue that intellectual representation of the ulama, in both polemics and academic critique, aided the state in its attempt to push the ulama from the center of intellectual and social life to the margins of ritual purity. Among my primary sources is a previously unexamined academic thesis authored by Qasim Tuysirkani in 1938.
Antoni Słonimski's UNESCO: On the Uses of International Organizations in Cold War Poland
Authors: Kunakhovich Kyrill 
Published: December 2024

“The world of today is torn asunder by a great dispute,” the Polish author Czesław Miłosz wrote in 1951. On one side lay the east, “under the domination of Moscow,” and on the other the west, encompassing the rest of the globe. “Trampled down by History—that elephant,” Poles found themselves sequestered in the east. Unless, like Miłosz, they had somehow “escaped” to the west, they were doomed to live “behind the iron curtain” in a “hermetically sealed . . . Eastern world.” Thanks partly to Miłosz's influence, this Cold War vision of a bifurcated world has thoroughly shaped scholarship on postwar Poland and the rest of eastern Europe. In recent years, however, it has been increasingly contested. Historians no longer speak of “parting” or “raising” the Iron Curtain but rather see this boundary as “nylon,” “airy,” and “porous.” They have uncovered an array of east-west ties as well as linkages along a different axis, north to south. These works belie the old idea of a “hermetically sealed . . . Eastern world” and also restore agency to its inhabitants. No longer “trampled down by history,” Poles now appear as “global citizens” who could “be part of the larger world and transcend the Cold War divide.” And yet one key way of transcending this divide still remains largely overlooked. While scholars explore points of contact between blocs in a “world . . . torn asunder,” they have been less attentive to the institutions that bound that world together: international organizations.
Who Won in 1989? Approaching the Canon of Czech Art History from a Feminist Perspective
Authors: Placáková Marianna 
Published: December 2024

AbstractDrawing on the classic question of feminist art history, this article asks how and by whom the contemporary canon of Czech art history was constructed, and when the exclusion of women artists of the 1980s generation from it took place. It shows that the 1960s generation of women artists emerged from the disruption of the traditional gender order in the Stalinist era. In contrast, the generation of women artists who entered the art scene in the 1980s was disadvantaged by the declining power of art institutional structures and the growing importance of informal networks for career success in late socialism. Their lack of social capital, combined with the re-emergence of macho culture in the 1980s art scene, the persistence of traditional gender roles in the home, and the loss of more substantial state support for artistic production after 1989, led to their “invisible” role in the post-1989 art world.
Constraints on the Observability of Energetic Neutral Atoms From the Magnetosphere‐Atmosphere Interactions at Callisto and Europa
Authors: Haynes C. Michael , Tippens Tyler , Simon Sven , Liuzzo Lucas 
Published: December 2024

AbstractWe investigate the emission of energetic neutral atoms (ENAs) from the magnetosphere‐atmosphere interactions at Europa and Callisto that may be observed by an ENA imaging instrument. To do so, we combine the draped electromagnetic fields from the AIKEF hybrid model with a tracing tool for the energetic magnetospheric parent ions. Using a realistic viewing geometry, synthetic ENA images are generated for multiple detector positions and orientations with respect to the magnetospheric field. At both moons, we investigate the ENA emission morphology at different distances to the center of Jupiter's plasma sheet. By generating ENA images for uniform electromagnetic fields as a baseline, we also constrain the influence of field line draping and induction signals on the observable ENA emission signatures. Our major findings are: (a) In uniform fields, regions of elevated ENA flux in the images populate segments of a ring around each moon's disc. (b) The radial and angular extensions of these segments decrease with growing magnetospheric field strength. (c) The angle between the detector's boresight vector and the ambient field determines the regions of the images populated with elevated ENA flux. (d) Non‐uniformities in the fields are discernible in the ENA images only when Europa and Callisto are located near the center of Jupiter's plasma sheet. Even in this case, the visibility of such features is restricted to certain viewing geometries. (e) Anisotropies in the moons' atmospheric density profiles produce gradients in the observable ENA emissions. This facilitates a global characterization of these neutral envelopes through ENA imaging.
