Dynamic Pulverization of Rock Under Triaxial Static-Stress and High-Rate Shearing
Authors: Liu Kai , Hu Wanrui , Zhao Jian 
Published: March 2024

AbstractA long-term opening problem in geophysics and engineering is the generation mechanism of rock pulverization (e.g., fault gouge) within the shear zone when subjected to triaxial stress environment and dynamic loads. A novel triaxial Hopkinson bar is developed to apply quasi-static triaxial confinement and dynamic loads onto the testing rocks and to measure the energy release from the shearing zone. The results elucidate shear strain-rate threshold (i.e., over 125 s−1) for granite at the triaxial prestress of (10, 10, 10) MPa is required for fine fragments/gouge generation. The effects of shear and normal pre-stresses on dynamic shear strength and surface energy for rock pulverization are investigated, which will help explain fine fragments formed during the high-rate loading events. It is suggested that, except for the quasi-static cumulative slip attrition and multiple dynamic events, rock pulverization or fault gouge could be generated at relatively shallow depths (low geo-stress) in a single dynamic earthquake processes.
It’s only a mirage: Tahar Djaout’s critique of logocentrism in L’Invention du désert
Authors: Aoudjit Abdelkader 
Published: March 2024

AbstractSet in Algeria, France, and the Arabian Peninsula in the early twelfth and the late twentieth centuries, L’Invention du désert is about an author who reexamines his life and his craft while writing a history of the Almoravid dynasty that ruled Andalusia and a large portion of the Maghreb from 1056 to 1152 CE. Accordingly, the novel is made of two basic narrative strands. The first focuses on the private musings and reminiscences of the narrator, moving forwards and backwards in space and time and going all the way to his childhood. The second narrative strand recounts the life, rise to power, and downfall of Mohamed ibn Toumert, the religious scholar and zealot whose followers brought down the Almoravids and founded the Almohad dynasty that lasted from 1152 to 1269 CE. The two major story-lines that constitute the novel are brought together by the narrator’s reflection on history and archiving for the purpose of problematizing the way Algerian history is conceived and used to address two major social and political concerns confronting Algerians: religious fundamentalism and national identity. The purpose of this article is to examine how Djaout uses the desert both as a topography and a metaphor to challenge the logocentrism of religious fundamentalism and narrow and essentialist definitions of Algerianess. The paper at the same time shows how the understanding and critique of historical logocentrism that are advanced in L’Invention du désert parallel Jacques Derrida’s philosophy put forward in Of Grammatology (Derrida in Of grammatology, Johns Hopkins University Press, Baltimore, 1976) and other early works. Because the manuscripts, critical of Islam as practiced under Almoravid rule, Ibn Toumert carries with him function as archives, the paper also engages with some of the themes Derrida developed later in Archive Fever: A Freudian Impression (Derrida in Archive fever: a Freudian impression, University of Chicago Press, Chicago, 1996).

AbstractIntervertebral disc degeneration (IVDD) is an aging disease that results in a low quality of life and heavy socioeconomic burden. The mitochondrial unfolded protein response (UPRmt) take part in various aging-related diseases. Our research intents to explore the role and underlying mechanism of UPRmt in IVDD. Nucleus pulposus (NP) cells were exposed to IL-1β and nicotinamide riboside (NR) served as UPRmt inducer to treat NP cells. Detection of ATP, NAD + and NADH were used to determine the function of mitochondria. MRI, Safranin O-fast green and Immunohistochemical examination were used to determine the degree of IVDD in vivo. In this study, we discovered that UPRmt was increased markedly in the NP cells of human IVDD tissues than in healthy controls. In vitro, UPRmt and mitophagy levels were promoted in NP cells treated with IL-1β. Upregulation of UPRmt by NR and Atf5 overexpression inhibited NP cell apoptosis and further improved mitophagy. Silencing of Pink1 reversed the protective effects of NR and inhibited mitophagy induced by the UPRmt. In vivo, NR might attenuate the degree of IDD by activating the UPRmt in rats. In summary, the UPRmt was involved in IVDD by regulating Pink1-induced mitophagy. Mitophagy induced by the UPRmt might be a latent treated target for IVDD.
Graphical Abstract
• UPRmt was upregulated in the NP cells of degenerative intervertebral disc.
• UPRmt regulated by Atf5 could activate mitophagy to protect NP cells from apoptosis.
• Nicotinamide riboside as UPRmt inducer reduced NP cells apoptosis, thereby delaying the process of IVDD.
Women marching for solidarity: 5 years of Aurat March in the Islamic Republic of Pakistan
Authors: Kelso Erin 
Published: March 2024

AbstractIn this paper, I argue that the Aurat March (Urdu: Woman March) in Pakistan has developed from a one-off event to a social movement that operates according to a populist logic as articulated by Ernesto Laclau (2018). I demonstrate how a diverse array of women’s demands is linked by a chain of equivalence to create solidarity between disparate communities of women. Here, all protestors define themselves in opposition to a common enemy, the patriarchy, allowing for a wide array of marginalized ethnic, religious and gender identities to be subsumed under the Aurat March banner. The sloganmera jism meri marzi(Urdu: my body, my choice) acts as a signifier that becomes increasingly empty, allowing a variety of demands to be projected upon it. I analyze conservative discourses around the Aurat March to demonstrate how right-wing detractors attempt to fill the empty signifier with morally charged content that disrupts the solidaric bonds holding together the Aurat March coalition. Finally, I explain how Aurat March organizers attempt to restore the openness of their signifier and the solidarity at the heart of their movement.
Estimation and usefulness of measurement uncertainty from sampling at different spatial scales: microns to kilometres
Authors: Ramsey Michael H. 
Published: March 2024

AbstractUncertainty of measurement values (MU) is crucial to their reliable geochemical interpretation. MU can be estimated using the Duplicate Method, which requires the taking of a small proportion of duplicated samples, and can be applied at any spatial scale. The distance between the duplicated samples is selected to reflect the effect of analyte heterogeneity on the measurement result (i.e. estimated concentration) within each sampling target, at the particular scale of investigation. Three published case studies, at different spatial scales, are used to explain how the Duplicate Method can be applied to estimate MU. They also illustrate how MU can be used to improve geochemical interpretation and validate measurement procedures (that include sampling) by judging their fitness for purpose. At the kilometre scale, measurements from the GEMAS survey of agricultural soils across Europe are used to estimate their MU for the first time. The MU for 53 elements range from an uncertainty factor of 1.01 to over 10. The MU contributes more that 20% to the total variance for 8 of the 53 elements, showing that the measurement procedure was not fit for purpose in those cases. At the micron scale, measurements of oxygen isotopes in candidate quartz reference materials had MU that was dominated by its sampling component, caused by sometimes unacceptable heterogeneity. A third case study of Pb in soils at 12 UK sites showed that the Duplicate Method can also be used to quantify the heterogeneity (as factor 1.03 to 2.4), and that it can indicate different possible sources of an element.
X-ray Insights into Fluid Flow During Rock Failures: Nonlinear Modeling of Fluid Flow Through Fractures with Varied Roughness

Published: March 2024

AbstractFluid flow and evolution mechanisms in fractured rocks are fundamental tasks in engineering fields such as geohazards prediction, geothermal resource exploitation, oil and gas exploitation, and geological sequestration of carbon dioxide. This study employed an enhanced X-ray imaging digital radiography to investigate nonlinear flow model of fluid through different roughness fractures. The X-ray images of fluid flow during rock failure were analyzed using a multi-threshold segmentation method applied to the X-ray absorption dose. The result show that a proposed nonlinear flow equation considers the joint roughness coefficient and the uniaxial compressive strength of the jointed rock, enabling a better understanding of the nonlinear flow behavior in fractured rock masses. This modeling approach has important theoretical and practical implications. By accounting for key factors influencing fluid flow behavior, it can help guide monitoring efforts to support early warning of fractured rock mass instability. Additionally, a more mechanistic understanding of flow processes may inform strategies to prevent engineering geological hazards.

AbstractFor a stratified groupG, we construct a class of Lie groups endowed with a left-invariant distribution locally diffeomorphic to the flat distribution ofG. Vice versa, we show that all Lie groups with a left-invariant distribution that is locally diffeomorphic to the flat distribution ofGbelong to the class we constructed, if the Lie algebra ofGhas finite Tanaka prolongation.

Published: March 2024

AbstractDue to the increase in the growth of data in this era of the digital world and limited resources, there is a need for more efficient data compression techniques for storing and transmitting data. Data compression can significantly reduce the amount of storage space and transmission time to store and transmit given data. More specifically, text compression has got more attention for effectively managing and processing data due to the increased use of the internet, digital devices, data transfer, etc. Over the years, various algorithms have been used for text compression such as Huffman coding, Lempel-Ziv-Welch (LZW) coding, arithmetic coding, etc. However, these methods have a limited compression ratio specifically for data storage applications where a considerable amount of data must be compressed to use storage resources efficiently. They consider individual characters to compress data. It can be more advantageous to consider words or sequences of words rather than individual characters to get a better compression ratio. Compressing individual characters results in a sizeable compressed representation due to their less repetition and structure in the data. In this paper, we proposed the ArthNgram model, in which the N-gram language model coupled with arithmetic coding is used to compress data more efficiently for data storage applications. The performance of the proposed model is evaluated based on compression ratio and compression speed. Results show that the proposed model performs better than traditional techniques.
Corneal biomechanics and diagnostics: a review﻿
Authors: Komninou Maria Angeliki , Seiler Theo G. , Enzmann Volker 
Published: March 2024

Abstract
Purpose
Corneal biomechanics is an emerging field and the interest into physical and biological interrelations in the anterior part of the eye has significantly increased during the past years. There are many factors that determine corneal biomechanics such as hormonal fluctuations, hydration and environmental factors. Other factors that can affect the corneas are the age, the intraocular pressure and the central corneal thickness. The purpose of this review is to evaluate the factors affecting corneal biomechanics and the recent advancements in non-destructive, in vivo measurement techniques for early detection and improved management of corneal diseases.

Methods
Until recently, corneal biomechanics could not be directly assessed in humans and were instead inferred from geometrical cornea analysis and ex vivo biomechanical testing. The current research has made strides in studying and creating non-destructive and contactless techniques to measure the biomechanical properties of the cornea in vivo.

Results
Research has indicated that altered corneal biomechanics contribute to diseases such as keratoconus and glaucoma. The identification of pathological corneas through the new measurement techniques is imperative for preventing postoperative complications.

Conclusions
Identification of pathological corneas is crucial for the prevention of postoperative complications. Therefore, a better understanding of corneal biomechanics will lead to earlier diagnosis of ectatic disorders, improve current refractive surgeries and allow for a better postoperative treatment.

Published: March 2024

AbstractPheromone communication is widespread among animals. Since it is often involved in mate choice, pheromone production is often tightly controlled. Although male sex pheromones (MSPs) and anti-aphrodisiacs have been studied in some Heliconius butterfly species, little is known about the factors affecting their production and release in these long-lived butterflies. Here, we investigate the effect of post-eclosion age on chemical blends from pheromone-emitting tissues in Heliconius atthis and Heliconius charithonia, exhibiting respectively free-mating and pupal-mating strategies that are hypothesised to differently affect the timing of their pheromone emissions. We focus on two different tissues: the wing androconia, responsible for MSPs used in courtship, and the genital tip, the production site for anti-aphrodisiac pheromones that affect post-mating behaviour. Gas chromatography-mass spectrometric analysis of tissue extracts from virgin males and females of both species from day 0 to 8 post-eclosion demonstrates the following. Some ubiquitous fatty acid precursors are already detectable at day 0. The complexity of the chemical blends increases with age regardless of tissue or sex. No obvious difference in the time course of blend production was evident between the two species, but female tissues in H. charithonia were more affected by age than in H. atthis. We suggest that compounds unique to male androconia and genitals and whose amount increases with age are potential candidates for future investigation into their roles as pheromones. While this analysis revealed some of the complexity in Heliconius chemical ecology, the effects of other factors, such as the time of day, remain unknown.

AbstractWe aimed to create a theoretical framework to understand how neighborhood gentrification may impact urban health and health equity, taking into account perspectives and evidence from multiple disciplines. In addition to reviewing the literature and harnessing our own experience and expertise, we elicited input from researchers, activists and professionals from multiple fields using an eDelphi process, determined the agreements and disagreements between respondents on the causes, consequences, and health impacts of gentrification. Respondents agreed that neighborhood gentrification has important implications for mental health and on many of the causes and consequences of gentrification but reached less agreement on the pathways by which gentrification may affect health and the specific health outcomes that may be affected. Finally, we generated an evidence-informed conceptual framework taking into account the input from the eDelphi process. Here we present this conceptual framework for understanding the relationship between gentrification and health and discuss a future research agenda for this emerging theme in public health research.

AbstractThe use of Cellular Automata (CA) in combination with Learning Automata (LA) has demonstrated effectiveness in handling hard-to-be-solved problems. Due to their capacity to learn and adapt, as well as their inherent parallelism, they can expedite the problem-solving process for a range of problems, such as challenging logic puzzles. One such puzzle is Sudoku, which poses a combinatorial optimization challenge of great difficulty and complexity. In this study, a Sudoku puzzle was represented as an Irregular Learning Cellular Automaton (ILCA), using a reward and penalty algorithm to resolve it. Simulations for an amount of 400 puzzles were performed, while the results demonstrate that the proposed algorithm operates effectively, highlighting the concurrent and learning capabilities of the ILCA structure. Furthermore, two different performance enhancement methods are investigated, namely learning rates method and selective probability reset rule, which are able to increase the initial performance by $$26.8\%$$

Remimazolam Attenuates LPS-Derived Cognitive Dysfunction via Subdiaphragmatic Vagus Nerve Target α7nAChR-Mediated Nrf2/HO-1 Signal Pathway
Authors: Zhou Zhan , Yang Ying , Wei Yi , Xie Yubo 
Published: March 2024

AbstractSepsis-induced neuroinflammation is significantly associated with sepsis-related brain dysfunction. Remimazolam is a novel ultra-short-acting benzodiazepine anesthetic with multiple organ protective effects. However, it is unknown whether remimazolam can ameliorate LPS-induced brain impairment. In this study, Lipopolysaccharide (5 mg/kg, LPS) severely impaired Sprague-Dawley rats spatial learning ability, memory, and cognitive function. However, remimazolam treatment showed a protective effect on LPS-induced cognitive dysfunction. Remimazolam partly reversed LPS-induced splenomegaly, decreased serum cytokine expression, suppressed hippocampal M1 microglial activation, and mitigated oxidative stress injury and neuroinflammation. Electroacupuncture (EA) or PNU282987 treatment improved LPS-induced cognitive dysfunction and also significantly inhibited neuroinflammation and systemic inflammation. However, MLA, ML385, or subdiaphragmatic vagus nerve (SDV) treatment abolished the protective effects of remimazolam. Further mechanistic studies showed that remimazolam induces protective effects by activating subdiaphragmatic vagus nerve target α7nAChR-mediated Nrf2/HO-1 signaling pathway. These results demonstrate that remimazolam can up-regulate α7nAChR, Cyto-Nrf2, HO-1, and cognitive-related (CREB, BDNF, PSD95) protein expressions, suppress M1 microglia, ameliorate neuroinflammation or systemic inflammation, and reverse cognitive dysfunction. Therefore, this study provides insight into a new therapeutic target for the treatment of sepsis-induced cerebral dysfunction.

Disaster risk management, climate change adaptation and the role of spatial and urban planning: evidence from European case studies
Authors: Farinós-Dasí Joaquín , Pinazo-Dallenbach Pablo , Peiró Sánchez-Manjavacas Enrique , Rodríguez-Bernal Diana Catalina 
Published: March 2024

AbstractThis paper advances knowledge and understanding of the relationships between risk management, climate change adaptation and spatial planning as good territorial governance practices. The aim is to present evidence on how risks and their management are progressively being integrated into national planning systems in order to reduce territorial vulnerability and costs related to natural events in the European context. This paper is based on the ESPON-TITAN project which focuses mainly on flood events that occurred in Rotterdam, Prague, the Po river basin, Pori, Andalucia, Nouvelle-Aquitaine, Dresden and the Alpine region. The paper reviews the literature and planning instruments applied in the selected case studies, as well as interviews with key stakeholders and decision makers. The results confirm the hypothesis that traditional disaster management is evolving towards Disaster Risk Management, clearly recognizing that Climate Change modifies and increases threats. Data on the consequences of natural disasters support the desirability of a proactive rather than a reactive approach, highlighting the crucial role of planning. The resulting governance is more "functional" than "territorial", leaving room for further advances and innovations such as territorial and multi-risk perspective, partnerships and civil society participation, and soft versus traditional hard or engineering solutions.
Testing the predictive ability of a karst subsidence susceptibility map made thirty years ago in the central Ebro Basin (Zaragoza, Spain)
Authors: Gracia-Abadías Javier , Simón José L. , Soriano M. Asunción , Salvador Tomás 
Published: March 2024

AbstractKarst subsidence has caused damage in numerous buildings and infrastructures in the surroundings of Zaragoza city since the early 1970s, when rapid urbanization of the area begun. A detailed survey carried out in 1991 allowed recognizing and mapping damages in an industrial district, and elaborating a susceptibility or spatial hazard map based on (i) the observed presence of active alluvial dolines, and (ii) spatial distribution of factors controlling their development, according to a hazard model based on both spatial analysis and laboratory experimental simulation. The predictive ability of such spatial hazard map is now tested, thirty years later, by a new detailed field survey carried out in 2021 covering almost the same area. The results allow mapping of the total present-day damage and, using GIS tools, also a residual map of areas newly damaged since 1991. After comparing those maps with the hazard zonation proposed in 1991, we conclude that: (i) the predictive ability of the latter is good in overall; (ii) the areas of highest subsidence hazard have a probability in the range of 19–38% of suffering damage over a 30-year period, while this probability systematically decreases up to about 7% for the lowest hazard areas; (iii) the average rate of occurrence of new damage within the overall study zone has remained quite uniform around 0.5% in area per year. Incorporating such calculations of temporal probability of occurrence associated to each hazard category allows the original susceptibility map to approach a hazard s.s. map, providing annual probabilities of occurrence between ~ 0.6 to 1.3% and ~ 0.3% for the distinct hazard zones.
