Facies-related reservoir heterogeneity of grain-supported limestones: insight from the Early Cretaceous Yamama Formation, southern Iraq
Authors: Mohammed Abbas , Velledits Felicitász 
Published: December 2024

AbstractSedimentological investigation of 150 m drill cores and well log analyses, including gamma-ray, resistivity, sonic, neutron, density logs, were conducted to constrain the impact of depositional facies on reservoir quality distribution in limestone succession of the Yamama Formation (Early Cretaceous), Nasiriya Oilfield, southern Iraq. Understanding the factors controlling reservoir heterogeneity in carbonate reservoirs is crucial for developing geological and reservoir models. Nine microfacies were identified: peloidal oncoidal grainstones-rudstones, skeletal cortoids packstones, skeletal dasyclads wackestones, pelletal packstones-grainstones, cortoidal peloidal grainstones, ooidal peloidal grainstones, skeletal grainstones, bioturbated dolomitic wackestones, and spiculitic skeletal mudstones-wackestones. The formation was deposited in open-marine shallow-water carbonate ramp, ranging from the intertidal to outer-ramp during the Berriasian-Valanginian. The depositional ramp was characterized by grainstones shoal barriers in the distal inner-ramp. Sea level fluctuations significantly influenced the vertical facies and reservoir quality distribution. The grain-supported, distal inner-ramp shoal facies formed the reservoir units, while the mud-supported, middle-outer-ramp facies are impervious units. Diagenetic processes, including dissolution of skeletal allochems, physical and chemical compaction, dolomitization, and cementation, have variably affected reservoir quality. Dissolution enhanced porosity by creating vuggs, while compaction and cementation often reduced porosity. Nevertheless, early diagenetic circumgranular calcite and small amount of scattered equant and syntaxial calcite overgrowths helped protecting the grain-supported limestones from physical compaction and thus preserved interparticle pores (≤ 22%) at depth (>3100 m). Conversely, equant calcite cement, which occurs in substantial amounts, has reduced porosity by filling the interparticle and moldic pores. Reservoir heterogeneity of the formation is attributed to depositional facies, which control the texture of the sediments, and to various types of diagenetic alterations.

An Investigation of Aberdeen Football Club’s Proposed Relocation from Pittodrie Stadium to the Town of Westhill
Authors: Bain Richie , James Kieran 
Published: November 2024

AbstractThe aim of this article is to investigate the impact of Aberdeen Football Club’s proposed relocation from Pittodrie Stadium to the environs of Westhill, almost seven miles west of the city-centre, and to assess the probability of acceptance amongst stakeholders of the football club. At the present time, writing in November 2024, it appears that the club has abandoned this plan. Instead, there is talk of a new stadium on the seafront not far from Pittodrie. However, the issues and stakeholder relationships revealed through this case remain worthy of extensive study for what they reveal about the intersection between the corporate world, the community organizations, and the hardcore supporter bases; and how each works according to a different logic and rhythm as they vie for power and ascendency. During the fieldwork, conducted in 2018-20, the opinions of shoppers in both Aberdeen and Westhill were canvassed, alongside the views of supporters from one of the popular Aberdeen FC supporters’ clubs.
The Role of Granulocyte Colony Stimulating Factor in Mitigating the Risk of Recurrent Miscarriages: A Comprehensive Review and Meta-Analysis
Authors: Zhang Biyun , Xu Jianying , Wei Xiangcai , Zhong Xingming 
Published: December 2024

AbstractGranulocyte colony-stimulating factor (G-CSF), a pivotal hematopoietic cytokine, has been noted for its potential to bolster embryo implantation and augment endometrial receptivity. The present meta-analysis endeavors to evaluate the therapeutic efficacy of G-CSF in mitigating the incidence of recurrent miscarriages, thereby enriching the clinical evidence supporting its use in treatment protocols. Our exhaustive literature search, concluded on August 25, 2024, spanned across various databases including PubMed, Medline, Cochrane Library, Web of Science, ClinicalTrials, China National Knowledge Infrastructure (CNKI), Weipu, and Wanfang, to identify and analyze randomized controlled trials (RCTs) that assessed the impact of G-CSF on recurrent miscarriage. Our review incorporated 7 RCTs. The application of G-CSF was linked to a marked reduction in the rate of miscarriage [RR = 0.48, 95% CI (0.27, 0.86), P = 0.01]. Subgroup analysis indicated that the intra-uterine infusion of G-CSF was notably effective in diminishing the miscarriage rate (RR = 0.35, 95% CI (0.18, 0.68), P = 0.002), while subcutaneous administration did not exhibit a significant impact (RR = 0.55, 95% CI (0.26, 1.20), P = 0.13). Moreover, the administration of G-CSF during the ovulatory phase was identified as particularly efficacious in reducing the miscarriage rate (RR = 0.33, 95% CI (0.18, 0.63), P < 0.001). Intrauterine administration of G-CSF, particularly during the ovulatory phase, is associated with a significant decrease in miscarriage risk and an enhancement in the likelihood of a successful pregnancy outcome in patients with a history of recurrent miscarriages. These findings highlight G-CSF’s promise as a valuable therapeutic intervention in this medical scenario.

Published: December 2024

AbstractThis paper examines the spatial distribution of chemical startups in the Visegrad Countries (Czech Republic, Slovakia, Poland, and Hungary), highlighting their potential to drive technological innovation by creating new products or services under conditions of high uncertainty. The study focuses on the proximity of these startups to medical or chemical universities and those with biotechnological research fields to better understand their geographical patterns and potential knowledge spillovers. Data were drawn from Crunchbase, a comprehensive startup database, resulting in a final sample of approximately 333 operational chemical, pharmaceutical, or biotechnological startups. Companies were identified using keyword-based searches, while startup locations and distances to the nearest medical universities were recorded. Statistical methods were applied to assess spatial patterns. Results indicate that these startups are frequently located in cities with biotechnological, chemical, or medical universities. Our findings highlight different types of startup activities and levels of financial support across the Visegrad countries, emphasising the role of chemical startups in fostering technological advancement and sustainable development.
A comparative study on Arc- and vacuum induction-melting for Ti16.6Zr16.6Hf16.6Co10Ni20Cu20 high entropy shape memory Alloy Production

AbstractArc-melting (AM) as a primary method for casting high entropy alloys (HEAs) ensures rapid alloy screening with minimal material input, high cost-effectiveness, and high cooling rates. However, the limitations of AM on a laboratory scale, particularly its constrained sample size and the necessity for remelting steps to ensure homogeneity, hampers thorough mechanical and functional testing of bulk materials. Therefore, this study features a comparative analysis between AM and vacuum induction-melting (VIM) techniques for High Entropy Shape Memory Alloys (HE-SMAs) production, focusing on the senary alloy Ti16.6Zr16.6Hf16.6Co10Ni20Cu20, known for its potential functional applications and high sensitivity to material inhomogeneity. The alloy’s composition, including high-melting point elements like Hf, Ti and Zr, makes it a well-suited candidate for assessing the capabilities of VIM in producing homogeneous bulk materials. The employment of binary pre-alloys in both AM and VIM processes reduced the necessity for remelting steps and ensured better initial quality for subsequent heat treatments. A homogenization treatment at 900 °C for 100 h of an AM-produced senary alloy showed only slight improvements compared to the same alloy produced via VIM, largely due to the slow diffusion of the larger Hf and Zr atoms from the dendrites into the solid solution. This suggests that VIM can achieve comparable levels of homogenization in substantially less time than required for AM-treated samples. The findings finally indicate that by using VIM, when combined with binary pre-alloys, one achieves more homogeneous alloys with reduced heat-treatment time, making it a viable method for HE-SMA production.
Survival of the flattest in the quasispecies model
Authors: Berger Maxime , Cerf Raphaël 
Published: December 2024

Abstract
Viruses present an amazing genetic variability. An ensemble of infecting viruses, also called a viral quasispecies, is a cloud of mutants centered around a specific genotype. The simplest model of evolution, whose equilibrium state is described by the quasispecies equation, is the Moran–Kingman model. For the sharp-peak landscape, we perform several exact computations and derive several exact formulas. We also obtain an exact formula for the quasispecies distribution, involving a series and the mean fitness. A very simple formula for the mean Hamming distance is derived, which is exact and does not require a specific asymptotic expansion (such as sending the length of the macromolecules to

$\infty$

or the mutation probability to 0). With the help of these formulas, we present an original proof for the well-known phenomenon of the error threshold. We recover the limiting quasispecies distribution in the long-chain regime. We try also to extend these formulas to a general fitness landscape. We obtain an equation involving the covariance of the fitness and the Hamming class number in the quasispecies distribution. Going beyond the sharp-peak landscape, we consider fitness landscapes having finitely many peaks and a plateau-type landscape. Finally, within this framework, we prove rigorously the possible occurrence of the survival of the flattest, a phenomenon which was previously discovered by Wilke et al. (Nature 412, 2001) and which has been investigated in several works (see e.g. Codoñer et al. (PLOS Pathogens2, 2006), Franklin et al. (Artificial Life25, 2019), Sardanyés et al. (J. Theoret. Biol.250, 2008), and Tejero et al. (BMC Evolutionary Biol.11, 2011)).

Abstract
We demonstrated a method to improve the output performance of a Ti:sapphire laser in the long-wavelength low-gain region with an efficient stimulated Raman scattering process. By shifting the wavelength of the high-gain-band Ti:sapphire laser to the long-wavelength low-gain region, high-performance Stokes operation was achieved in the original long-wavelength low-gain region of the Ti:sapphire laser. With the fundamental wavelength tuning from 870 to 930 nm, first-order Stokes output exceeding 2.5 W was obtained at 930–1000 nm, which was significantly higher than that directly generated by the Ti:sapphire laser, accompanied by better beam quality, shorter pulse duration and narrower linewidth. Under the pump power of 42.1 W, a maximum first-order Stokes power of 3.24 W was obtained at 960 nm, with a conversion efficiency of 7.7%. Furthermore, self-mode-locked modulations of first- and second-order Stokes generation were observed in Ti:sapphire intracavity solid Raman lasers for the first time.
Becoming Better: When and Why Positive Status Change Induces Prosocial Behavior Versus Self-Interested Behavior
Authors: Zhang Zhe , Yueqiao Qiao , Jia Ming , Ju Boyuan , Wang Xingquan 
Published: December 2024

AbstractPrior research on status has focused primarily on the cognitive perspective, exploring the effects of status and offering a limited understanding of the impact of positive status change and its emotional mechanisms. This study draws upon the two-facet model of pride to examine how positive status change influences the behaviors of new status holders. Specifically, we propose that when status differentiation is low, positive status change enhances new status holders' prosocial behavior through their authentic pride, while in cases of high status differentiation, it increases their self-interested behavior through their hubristic pride. To test our hypotheses, we conducted a series of studies, including a laboratory experiment, a scenario experiment, and a time-lagged multilevel and multisource field study. Our multilevel analyses of the data provided strong support for our hypotheses. Our findings shed light on when and why positive status change triggers different behaviors among new status holders, offering important insights into the emotional mechanisms that underlie the effects of status change.

AbstractBackgroundSevere fatigue and cognitive complaints are frequently reported after SARS-CoV-2 infection and may be accompanied by depressive symptoms and/or limitations in physical functioning. The long-term sequelae of COVID-19 may be influenced by biomedical, psychological, and social factors, the interplay of which is largely understudied over time. We aimed to investigate how the interplay of these factors contribute to the persistence of symptoms after COVID-19.MethodsRECoVERED, a prospective cohort study in Amsterdam, the Netherlands, enrolled participants aged⩾16 years after SARS-CoV-2 diagnosis. We used a structural network analysis to assess relationships between biomedical (initial COVID-19 severity, inflammation markers), psychological (illness perceptions, coping, resilience), and social factors (loneliness, negative life events) and persistent symptoms 24 months after initial disease (severe fatigue, difficulty concentrating, depressive symptoms and limitations in physical functioning). Causal discovery, an explorative data-driven approach testing all possible associations and retaining the most likely model, was performed.ResultsData from 235/303 participants (77.6%) who completed the month 24 study visit were analysed. The structural model revealed associations between the putative factors and outcomes. The outcomes clustered together with severe fatigue as its central point. Loneliness, fear avoidance in response to symptoms, and illness perceptions were directly linked to the outcomes. Biological (inflammatory markers) and clinical (severity of initial illness) variables were connected to the outcomes only via psychological or social variables.ConclusionsOur findings support a model where biomedical, psychological, and social factors contribute to the development of long-term sequelae of SARS-CoV-2 infection.
Identification of mobile resistome in soils exposed to different impacts in Fildes Peninsula, King George Island
Authors: Giménez Matías , Azziz Gastón , Batista Silvia 
Published: December 2024

AbstractAntimicrobial resistance is one of the most important global health issues identified in recent decades. Different approaches have been used to establish the presence and abundance of antimicrobial resistance genes (ARGEs) in the environment. In this study, we analysed soil samples from Fildes Peninsula (King George Island, Maritime Antarctica) exposed to human and bird impacts. The objective of the work was to identify ARGEs in the samples and to evaluate whether these genes were located in plasmids using two different strategies. A metagenomic analysis was employed to identify ARGEs according to the CARD database and to determine whether they were associated with plasmidic sequences. The analysis showed that the site exposed to high anthropogenic activity had a higher number of ARGEs compared to other sites. A large percentage of those ARGEs (19.4%) was located in plasmidic contigs. We also assessed replicon mobilization using microbial communities from these soil samples as donors through an exogenous plasmid isolation method. In this case, we could recover plasmids with ARGEs in a Tcr transconjugant clone. Although they could not be fully assembled, we could detect broad host range IncP1 and IncQ plasmid sequences. Our results indicate that sewage-impacted soils could be hotspots for the spread of ARGEs into the Antarctic environment.

Published: December 2024

Abstract
To meet the specific education needs of ethics committee members (primarily full-time healthcare professionals), the Regional Ethics Department of Kaiser Permanente Northern California (KPNCAL) and Washington State University’s Elson Floyd School of Medicine have partnered to create a one-academic year Medical Ethics Certificate Program. The mission-driven nature of the KPNCAL-WSU’s Certificate Program was designed to be a low-cost, high-quality option for busy full-time practitioners who may not otherwise opt to pursue additional education.
This article discusses the specific competency-focused methodologies and pedagogies adopted, as well as how the Certificate Program made permanent changes in response to the global pandemic. This article also discusses in detail one of the Program’s signature features, its Practicum—an extensive simulated clinical ethics consultation placing students in the role of ethics consultant, facilitating a conflict between family members played by paid professional actors. This article concludes with survey data responses from Program alumni gathered as part of a quality study.

Published: December 2024

AbstractBackground:Early recognition of cardiac involvement and prediction of disease prognosis are essential for the management of inflammatory diseases such as multisystem inflammatory syndrome. This study aimed to investigate the role of Pentraxin-3 levels in identifying cardiac involvement and evaluating disease severity in patients with multisystem inflammatory syndrome.Methods:The study included 56 multisystem inflammatory syndrome patients and 26 healthy children as a control group. The multisystem inflammatory syndrome group was divided into those with cardiac involvement (n = 34) and those without (n = 22), as well as those with clinically mild-moderate (n = 30) and severe (n = 26) multisystem inflammatory syndrome. Blood samples for measurement of Pentraxin-3 levels were obtained from all patients before treatment and from the healthy controls.Results:In the patient group, the mean age was 8.2 ± 4 years (range: 2–17 years), and the male-to-female ratio was 1.8. In the control group, these values were 9.5 ± 3.7 years (range: 2–16 years) and 1.9, respectively (p > 0.05). Plasma Pentraxin-3 levels were significantly higher in multisystem inflammatory syndrome patients compared to controls (7.1 ± 5 ng/mL vs. 2.9 ± 2.1 ng/mL, p = 0.001). Patients with cardiac involvement had a significantly higher median Pentraxin-3 level than those without (5.8 ng/mL vs. 4.1 ng/mL, p = 0.004). Severe disease was also associated with a higher median Pentraxin-3 level compared to mild-moderate disease (6.1 ng/mL vs. 4.4 ng/mL, p = 0.001). Pentraxin-3 level was negatively correlated with left ventricular ejection fraction and positively correlated with B-type natriuretic peptide, troponin.Conclusion:Elevated Pentraxin-3 levels in multisystem inflammatory syndrome patients may help predict the clinical course of the disease and cardiac involvement. However, larger-scale prospective studies are needed to further elucidate this.
Variability in River Width Reveals Climatic Influence on Channel Geometry

Published: November 2024

AbstractDuring a flood, the geometry of a river channel constrains the flows of water and sediment, however, over many floods, bankfull channel geometry evolves to reflect the longer‐term fluxes of water and sediment supplied by the catchment. Physics‐based models predict the average relationship between bankfull geometry and discharge to within an order of magnitude, however, observed variability about the prediction remains unaccounted for. We used high‐resolution topography to extract continuous measurements of bankfull width from 67 sites spanning the continental United States, yielding a reach‐scale probabilistic description of river width for each site. Within an individual reach, bankfull river width is well‐described by a lognormal distribution. Rivers that spend a greater proportion of time above bankfull are wider for the same bankfull discharge, revealing an unrecognized pathway through which climatic or engineered changes in flow frequency could alter river geometry and therefore impact aquatic habitat and flooding risk.
