3D modeling of geological and geotechnical soil characterization using the MASW method: a case study in Southern Ijaw LGA, Bayelsa State, Nigeria
Authors: Macquen Bello Akpoku , OBorie Ebiegberi , Eteh Desmond Rowland 
Published: November 2024

AbstractThe Multichannel Analysis of Surface Waves (MASW) method is pivotal for non-invasive subsurface shear-wave velocity profiling, essential in geotechnical and seismic investigations. This study aims to model 3D geological and geotechnical soil properties in Southern Ijaw LGA, Bayelsa State, Nigeria, using MASW. Data collection involved a 12-channel ABEM Terraloc Mark 6 geophone system across nine survey points, complemented by nine boreholes and two Standard Penetration Tests (SPT). The results revealed a shallow water table at 0.30 m and stratified soil layers ranging from soft clay to dense sands. SPT N-values increased from 2 at the surface to 34 in deeper layers, reflecting significant soil densification and strength enhancement with depth. Shear-wave velocities (Vs) ranged from 207.11 m/s at 0.87 m to 502.88 m/s at 12.9 m, while compressional-wave velocities (Vp) ranged from 388.71 m/s to 948.98 m/s. Poisson’s ratio was consistent at 0.3, indicating uniform properties across depths. Elastic moduli, including shear modulus (µ), Young’s modulus (E), and bulk modulus (K), increased with depth, indicating greater subsurface material stiffness. The 3D geological model delineated distinct layers: soft clay (0–3.61 m), silty clay (3.61–5.19 m), fine sand (5.19–6.55 m), medium sand (6.55–7.83 m), and medium to coarse sand (7.83–12.90 m). These layers exhibited specific engineering properties, with ultimate and allowable bearing capacities ranging from 154.38 to 543.71 kPa and 51.46 to 181.24 kPa, respectively. MASW-derived N-values showed a strong correlation with traditional SPT N-values (R2 = 0.9401) and shear wave velocities and SPT N-values (R2 = 0.961), confirming MASW's effectiveness for geotechnical characterization. This enhances the precision of 3D soil models and supports more informed engineering decisions. The findings significantly advance the understanding of soil properties, particularly in the Niger Delta.
The Art of Disruption: Decolonial Potentiality in Fatou Cissé’s La ville en mouv’ment
Authors: Swanson Amy 
Published: November 2024

AbstractAfrican contemporary choreographers increasingly delink from Eurocentric performance conventions and work toward establishing local conditions of production and consumption by performing in public spaces. Although the labor undertaken to shift power asymmetries does not always result in structural changes, their art may be considered decolonial creative expression. Based on ethnographic research at the third and fourth editions (2022 and 2023) of Fatou Cissé’s street performance festival, La ville en mouv’ment (The City in Movement), in Dakar, Senegal, the author argues that decolonial potentiality extends beyond the precarious economic conditions to encapsulate the artists’ return to public space and futurist aesthetics.
Is Communications-Company Ownership of Video Content a Threat to Competition?
Authors: Crandall Robert W. 
Published: November 2024

Abstract
For the past decade, U.S. communications policymakers have been debating the need for net-neutrality regulation of “dominant” communications carrier platforms. One of the reasons advanced for regulating these carriers derives from a fear that carriers could reduce competition in the production and distribution of video media through their ownership of media companies, but is there any evidence supporting the notion that vertically integrated communications companies have successfully used such a strategy? This paper provides evidence from the financial markets that carrier integration into video production has not redounded to the benefit of these companies’ stockholders. In fact, this integration appears to reduce the value that investors place on such carriers, a result that suggests that the difficulties in managing a large, vertically integrated media and communications company more than offset any benefits (if any) that may derive from anticompetitive behavior induced by vertical integration.
Towards anarchist abolitionist futures for violence prevention: Beyond ‘counterterrorism’
Authors: Dixit Priya 
Published: November 2024

Abstract
Recent critical scholarship on terrorism has centred on matters of race, class, and gender regarding how counterterrorism policies are connected to multiple systems of hierarchical power relations. This article builds upon this scholarship and looks towards the future. It engages with understandings of emancipatory futures in critical scholarship on terrorism while drawing upon abolitionist and anarchist political thought to expand understandings of such futures. Anarchist and abolitionist thinking are useful for considering futures beyond the ‘global war on terror’ (GWOT) because of their anti-state and anti-domination orientations and focus on building alternatives to prevent and manage violence apart from contemporary ‘counterterrorism’. After providing an outline of anarchist and abolitionist thought, the article connects these to contemporary examples drawn from the United States and Nepal. In doing so, it theorises and imagines futures for preventing violence and building public security that are linkedto anarchist and abolitionist understandings of violence and the state. In contrast to ‘power politics’ which centres on the state, an anarchist abolitionist approach explores how safety and security can be reimagined and remadein the absence of a state.
Implementing culturally appropriate recovery approaches in mental health services: perspectives from the Irish Traveller community
Authors: Villani J. , Kuosmanen T. , McDonagh M. , Barry M.M. 
Published: November 2024

Abstract

Objectives:
This study explores the perspectives of Irish Travellers, an ethnic minority group in Ireland, on the service improvements needed to implement culturally appropriate recovery approaches in mental health services.

Methods:
A community-based participatory research approach was employed. Seventeen Traveller peer researchers conducted thirteen qualitative participatory workshops and five individual interviews across Ireland. Eighty-seven adult members of the Traveller community (83% female, mean age = 33, 56.3% not in education or employment) were recruited through convenience sampling. Participatory thematic analysis was employed.

Results:
Travellers’ ideas about improvements in mental healthcare involve practitioners in creating a trusting environment, increasing representation of Travellers within mental healthcare staff and working in partnership with Traveller service users to co-produce strategies that are owned by the community. Study participants emphasised the importance of Traveller cultural awareness, strengthening trauma-informed care, and embedding an ethos of cultural humility within mainstream services. The findings indicate the need for increased collaboration between mental health service providers and non-mental health agencies, and a reorientation of care towards empowering Traveller service users to achieve their social aspirations and building a positive self-identity.

Conclusions:
This study demonstrates that implementing a recovery approach for Travellers requires a reorientation of services, in line with Travellers’ definition of culturally appropriate mental healthcare. This study calls for an expanded mandate for mental health services beyond individual care and towards intersectoral action in addressing the social determinants of Travellers’ mental health. This will help to shape an equitable and inclusive healthcare setting that promotes Travellers’ mental health and recovery.
Infrastructures of Repair
Authors: Arteaga Rachel 
Published: November 2024

Abstract
The future of public humanities will be determined by the infrastructural investments that support its continued development. These include, in the context of the United States, increased federal funding for the National Endowment for the Humanities; a serious re-engagement in the material support of new humanities scholarly production by private foundations; and a focused effort by humanities organizations to cultivate philanthropic donors. This manifesto argues that the humanities are the rightful inheritance of every person, regardless of background or position. If we are to take seriously both the resource needs of humanities research—which demand that funds be allocated for highly trained scholars to read, interpret, authenticate, preserve, and circulate primary source material—and the idea that no one has a higher claim than anyone else to these sources and processes and the insights they yield—which demands that individuals outside of the academy explicitly experience them selves as equal participants in the humanities—then our approach to both research infrastructure and public engagement must radically shift to emphasize repair. Repair, here, is the interpersonal, intellectual, strategic, repetitious, time-intensive work of ensuring that every individual can claim this rightful cultural inheritance. It is the work of creating the conditions for encounters between individuals and the vastness of history, culture, and difference. The future of public humanities must be in the creation of replicable models for these encounters, in the knowledge that in every instance, the work of the humanities is and must be unreproducible.

EXTENDING CONGRUENCES FOR OVERPARTITIONS WITH
$\ell $
-REGULAR NONOVERLINED PARTS
Authors: SELLERS JAMES A. 
Published: November 2024

Abstract
Recently, Alanazi et al. [‘Refining overpartitions by properties of nonoverlined parts’, Contrib. Discrete Math.17(2) (2022), 96–111] considered overpartitions wherein the nonoverlined parts must be

$\ell $

-regular, that is, the nonoverlined parts cannot be divisible by the integer

$\ell $

. In the process, they proved a general parity result for the corresponding enumerating functions. They also proved some specific congruences for the case

$\ell =3$

. In this paper we use elementary generating function manipulations to significantly extend this set of known congruences for these functions.
A comparative meta-analysis of structural magnetic resonance imaging studies and gene expression profiles revealing the similarities and differences between late life depression and mild cognitive impairment

Published: November 2024

AbstractBackgroundLate-life depression (LLD) predisposes individuals to cognitive decline, often leading to misdiagnoses as mild cognitive impairment (MCI). Voxel-based morphometry (VBM) can distinguish the profiles of these disorders according to gray matter (GM) volumes. We integrated findings from previous VBM studies for comparative analysis and extended the research into molecular profiles to facilitate inspection and intervention.MethodsWe comprehensively searched PubMed and Web of Science for VBM studies that compared LLD and MCI cases with matched healthy controls (HCs) from inception to 31st December 2023. We included 13 studies on LLD (414 LLDs, 350 HCs) and 50 on MCI (1878 MCIs, 2046 HCs). Seed-based d Mapping with Permutation of Subject Images (SDM-PSI) was used for voxel-based meta-analysis to assess GM atrophy, spatially correlated with neuropsychological profiles. We then used multimodal and linear-model analysis to assess the similarities and differences in GM volumetric changing patterns. Partial least squares (PLS) regression and gene enrichment were employed for transcription-neuroimaging associations.ResultsGM volumes in the left hippocampus and right parahippocampal gyrus are more affected in MCI, along with memory impairment. MCI was spatially correlated with a more extensive reduction in the levels of neurotransmitters and a severe downregulation of genes related to cellular potassium ion transport and metal ion transmembrane transporter activity.ConclusionCompared to LLD, MCI exhibited more GM atrophy in the hippocampus and parahippocampal gyrus and lower gene expression of ion transmembrane transport. Our findings provided imaging-transcriptomic-genetic integrative profiles for differential diagnosis and precise intervention between LLD and MCI.
Unexpected Transient Dynamics of Meandering Rivers With Unsteady Flows
Authors: Bassani Francesca , Bertagni Matteo B. , Ridolfi Luca , Camporeale Carlo 
Published: November 2024

AbstractRiver meandering dynamics are here explored in light of unsteady water flows. While mathematical models have usually focused on constant discharges—a reasonable and widely adopted approach for long‐term considerations—we show that varying flows strongly affect the short‐term planimetric evolution of meanders, before the cutoff occurrence. In particular, flow variability slows down the meanders' dynamics while does not significantly influence the wavelength selection. We support our arguments with numerical simulations and theoretical (linear and nonlinear) analyses, showing that an interplay between out‐of‐phase river geometry and flow is responsible for the meander‐dynamics slowdown. Our results suggest that accounting for flow variability is critical in assessing yearly to decadal meander dynamics with important implications for river engineering and management strategies.
Considering severity in the design of reproductive genetic carrier screening programs: screening for severe conditions

Published: November 2024

Abstract
Reproductive genetic carrier screening (RGCS) provides information about people’s chance of having children with certain genetic conditions, to inform reproductive decision making. RGCS at population scale requires a robust and streamlined program that is purposively designed and formally implemented to ensure equity and consistency. There are many considerations in selecting conditions, genes and variants for inclusion in RGCS, with severity of the genetic condition a key criterion. However, the concept of severity is complex and often underspecified in available guidelines. Severity is often determined in relation to other contextual features and can be experienced differently by individuals who all have the same condition. While some genetic conditions are unambiguously considered severe, there are many factors that contribute to how severe a condition is perceived to be (and by whom), and perspectives will vary. In this paper, we analyse why severity is an important criterion when selecting conditions, genes or variants to be included in RGCS. We suggest that screening programs should be oriented more towards variants and genes associated with severe conditions. We discuss the importance of taking a practical approach to gene selection in a carrier screening program when presenting the offer at population scale.
Causal inference concepts can guide research into the effects of climate on infectious diseases

Published: November 2024

Abstract
A pressing question resulting from global warming is how climate change will affect infectious diseases. Answering this question requires research into the effects of weather on the population dynamics of transmission and infection; elucidating these effects, however, has proved difficult due to the challenges of assessing causality from the predominantly observational data available in epidemiological research. Here we show how concepts from causal inference—the sub-field of statistics aiming at inferring causality from data—can guide that research. Through a series of case studies, we illustrate how such concepts can help assess study design and strategically choose a study’s location, evaluate and reduce the risk of bias, and interpret the multifaceted effects of meteorological variables on transmission. More broadly, we argue that interdisciplinary approaches based on explicit causal frameworks are crucial for reliably estimating the effect of weather and accurately predicting the consequences of climate change.

Abstract
Electrocatalytic water splitting is a promising approach for clean hydrogen production, but the process is hindered by the sluggish kinetics of the anodic oxygen evolution reaction (OER) owing to the spin-dependent electron transfer process. Efforts to control spin through chirality and magnetization have shown potential in enhancing OER performance. Here we harnessed the potential of topological chiral semimetals (RhSi, RhSn and RhBiS) and their spin-polarized Fermi surfaces to promote the spin-dependent electron transfer in the OER, addressing the traditional volcano-plot limitations. We show that OER activities follow the trend RhSi < RhSn < RhBiS, corresponding to the increasing extent of spin–orbit coupling (SOC). The chiral single crystals outperform achiral counterparts (RhTe2, RhTe and RuO2) in alkaline electrolyte, with RhBiS exhibiting a specific activity two orders of magnitude higher than RuO2. Our work reveals the pivotal roles of chirality and SOC in spin-dependent catalysis, facilitating the design of ultra-efficient chiral catalysts.

AbstractÅngstrom and attosecond are the fundamental spatiotemporal scales for electron dynamics in various materials. Although attosecond pulses with wavelengths comparable to the atomic scales are expected to be a key tool in advancing attosecond science, producing high-power hard X-ray attosecond pulses at ångstrom wavelengths remains a formidable challenge. Here, we report the generation of terawatt-scale attosecond hard X-ray pulses using a free-electron laser in a special operation mode. We achieved 9 keV single-spike X-ray pulses with a mean pulse energy of around 180 μJ, exceeding previous reports by more than an order of magnitude, and an estimated average pulse duration of 200 as at full-width at half-maximum. Exploiting the unique capability of the European XFEL, which can deliver ten pulse trains per second with each containing hundreds of pulses at megahertz repetition rates, this study demonstrates the generation of attosecond X-ray pulses at a 2.25 MHz repetition rate. These intense high-repetition-rate attosecond X-ray pulses present transformative prospects for structural and electronic damage-free X-ray measurements and attosecond time-resolved X-ray methodologies, heralding a new era in ultrafast X-ray science.

AbstractIn the present paper, we introduce a high-resolution spatiotemporal point cloud time series, acquired using a LiDAR sensor mounted 30 metres above ground on a flux observation tower monitoring a boreal forest. The dataset comprises a 18-month long (April 2020 - September 2021) time series with an average interval of 3.5 days between observations. The data acquisition, transfer, and storage systems established at Hyytiälä (Finland) are named the LiDAR Phenology station (LiPhe). The dataset consists of 103 time points of LiDAR point clouds covering a total of 458 individual trees, comprising three distinct Boreal species. Additional reference information includes the respective location, the species, and the initial height (at the first time point) of each individual tree. The processing scripts are included to outline the workflow used to generate the individual tree point clouds (LiPheKit). The presented dataset offers a comprehensive insight into inter- and intra-species variations of the individual trees regarding their growth strategies, phenological dynamics, and other functioning processes over two growth seasons.
Tuning load redistribution and damage near heterogeneous interfaces

Published: November 2024

AbstractWe investigate interface failure of model materials representing architected thin films in contact with heterogeneous substrates. We find that, while systems with statistically isotropic distributions of impurities derive their fracture strength from the ability to develop rough detachment fronts, materials with hierarchical microstructures confine failure near a prescribed surface, where crack growth is arrested and crack surface correlations are suppressed. We develop a theory of network Green’s functions for the systems at hand, and we find that the ability of hierarchical microstructures to control failure mode and locations comes at no performance cost in terms of peak stress and specific work of failure and derives from the quenched local anistotropy of the elastic interaction kernel.
