Positioning Ethics When Direct Patient Care is Prioritized: Experiences from Implementing Ethics Case Reflection Rounds in Childhood Cancer Care
Authors: Pergert Pernilla , Molewijk Bert , Bartholdson Cecilia 
Published: November 2024

AbstractCaring for children with cancer involves complex ethical challenges. Ethics Case Reflection (ECR) rounds can be offered to support teams to reflect on challenges and what should be done in patient care. A training course, for facilitators of ECR rounds, has been offered to healthcare professionals (HCPs) in childhood cancer care by a Nordic working group on ethics. During/after the course, the trainees implemented and facilitated ECR rounds in their clinical setting. The aim was to explore the trainees’ experiences of implementing ECR rounds in childhood cancer care. HCPs, who participated as trainees in the course, participated in 3 focus group interviews (n = 22) and 27 individual interviews (n = 17). Interview data were analysed concurrently with data collection following classic grounded theory. Positioning ethics is the core category in this study, used to resolve the main concern of doing ethics in a context where direct patient care is prioritized. Being able to take time for ethics reflections, not perceived as the key priority, was considered a luxury in the clinical setting. Strategies for positioning ethics include allying, promoting ethics reflection, scheduling ethics reflection, and identifying ethical dilemmas. These strategies can be more or less successful and vary in intensity. The prioritisation of direct patient care is not surprising, but polarisation between care and ethics needs to be questioned and ethics reflection need to be integrated in standard care. Ethical competence seems to be central in doing ethics and more knowledge on the promotion of ethical competence in practice and education is needed.

Published: November 2024

AbstractHeavy metals are among the problematic groups of contaminants. They are discharged from various industries. The wastewater disposed by heavy metals is causing major hazards to the environment. Different hydrogels based on Gelatin (gelt/AAm/EDTA) and nano- (Fe3O4/gelt/AAm/EDTA) were prepared by gamma radiation at 60 KGy and employed for heavy metals elimination. The structure and surface morphology of the manufactured hydrogels were confirmed with FTIR, X-ray, surface area, and SEM. The prepared hydrogels were characterized in terms of their gel content. The swelling properties were studied as a function of time. This research aims to investigate the adsorption properties of diverse hydrogels concerning heavy metal ions, specifically copper, cobalt, and nickel. The impact of key experimental factors, including initial metal concentration, temperature, time, and pH, was inspected via batch adsorption experiments utilizing atomic absorption spectroscopy. It was found that the adsorption of Cu+2‏, Co+2‏ and Ni+2‏ ions is pH-dependent, and the optimal pH for adsorption of Cu+2 is pH 4‏, Co+2 ‏is 5, and Ni+2‏ is 4. The highest metals removal was copper, nickel, and cobalt ions by nano (Fe3O4/gelt/AAm/EDTA) hydrogel with removal percent 98.5% for Cu+2, 96.8%for Ni+2, and 93.9%for Co+2.

Condensation in Zero-Range Processes with a Fast Rate
Authors: Jatuviriyapornchai Watthanan , Grosskinsky Stefan 
Published: November 2024

AbstractWe introduce a simple zero-range process with constant rates and one fast rate for a particular occupation number, which diverges with the system size. Surprisingly, this minor modification induces a condensation transition in the thermodynamic limit, where the structure of the condensed phase depends on the scaling of the fast rate. We study this transition and its dependence on system parameters in detail on a rigorous level using size-biased sampling. This approach generalizes to any particle system with stationary product measures, and the techniques used in this paper provide a foundation for a more systematic understanding of condensing models with a non-trivial condensed phase.
The Role of Baby-Friendly Designated Hospitals in Breastfeeding Initiation Across Racial/Ethnic Groups in Florida
Authors: Lebron Cynthia N. , Larson Michaela , Chavez Jennifer , Parra Alexa 
Published: November 2024

Abstract
Background
Baby-Friendly Hospitals (BFH) in the United States (U.S.) are associated with higher breastfeeding initiation rates. Breastfeeding is associated with a myriad of favorable health outcomes for both mother and child. However, few studies have examined the impact of breastfeeding support resources, like BFH, on breastfeeding initiation among minority groups. The objective of this study is to evaluate the association between birth at a BFH and the breastfeeding initiation in Florida.

Methods
A retrospective exploratory analysis of BFH and birth certificate data (n=3,321,022 ) from 2004-2022 from Florida was conducted. A logistic regression model was fit to examine the main and interaction effects of race/ethnicity and birth at a BFH on breastfeeding initiation. Time was included as a sequential variable to adjust for temporal effects. Covariates known to impact breastfeeding initiation rates, including maternal education and prenatal care utilization, were included in multivariate analyses.

Results
Of births at a BFH, 89% of mothers initiated breastfeeding. Comparatively, of the births at a non-BFH, 84% of mothers initiated breastfeeding. Giving birth at a BFH increased the odds of breastfeeding initiation by at least 42% (OR = 1.42, CI: 1.38-1.45, p <0.001, Hispanic White mothers) in unadjusted models and 10% (OR = 1.10, CI: 1.03-1.17, p = 0.004, other non-Hispanic mothers) in adjusted models. However, BFH may have differential effects by maternal race and ethnicity. In the multivariate model adjusting for relevant covariates, non-Hispanic Black mothers who gave birth at a BFH were 27% less likely to initiate breastfeeding compared to mothers that gave birth at a non-BFH (OR = 0.73, CI: 0.61- 0.88, p < 0.001; interaction term for BFH*maternal race/ethnicity). Similar trends were observed for Hispanic Black, Hispanic White, and other non-Hispanic mothers.

Conclusions
Giving birth at a BFH is associated with greater odds of breastfeeding initiation. However, when considering the race and ethnicity of mothers, these odds significantly decline, indicating a need to further explore the barriers that may preclude non-Hispanic Black and Hispanic moms from receiving the same benefits of BFH.
Understanding with Toy Surrogate Models in Machine Learning
Authors: Páez Andrés 
Published: November 2024

AbstractIn the natural and social sciences, it is common to use toy models—extremely simple and highly idealized representations—to understand complex phenomena. Some of the simple surrogate models used to understand opaque machine learning (ML) models, such as rule lists and sparse decision trees, bear some resemblance to scientific toy models. They allow non-experts to understand how an opaque ML model works globally via a much simpler model that highlights the most relevant features of the input space and their effect on the output. The obvious difference is that the common target of a toy and a full-scale model in the sciences is some phenomenon in the world, while the target of a surrogate model is another model. This essential difference makes toy surrogate models (TSMs) a new object of study for theories of understanding, one that is not easily accommodated under current analyses. This paper provides an account of what it means to understand an opaque ML model globally with the aid of such simple models.
Artificial Intelligence, Discrimination, Fairness, and Other Moral Concerns
Authors: Segev Re’em 
Published: November 2024

AbstractShould the input data of artificial intelligence (AI) systems include factors such as race or sex when these factors may be indicative of morally significant facts? More importantly, is it wrong to rely on the output of AI tools whose input includes factors such as race or sex? And is it wrong to rely on the output of AI systems when it is correlated with factors such as race or sex (whether or not its input includes such factors)? The answers to these questions are controversial. In this paper, I argue for the following claims. First, since factors such as race or sex are not morally significant in themselves, including such factors in the input data, or relying on output that includes such factors or is correlated with them, is neither objectionable (for example, unfair) nor commendable in itself. Second, sometimes (but not always) there are derivative reasons against such actions due to the relationship between factors such as race or sex and facts that are morally significant (ultimately) in themselves. Finally, even if there are such derivative reasons, they are not necessarily decisive since there are sometimes also countervailing reasons. Accordingly, the moral status of the above actions is contingent.

AbstractThe aim of this paper is to present a methodology for implementing the high-energy orbits which is still an open problem for nonlinear energy harvesters. To achieve it, this paper presents a new design of system with a flag configuration which potential function is shaped with the use of elastic elements. We have identified the lift force in FEM for wide spectrum of air velocities and used it as excitation in dimensionless mathematical model. On this basis we have conducted simulations of energy harvesting effectiveness. In the second part of the work, we focused on identifying the coexisting solutions. Due to the existence of high-energy orbits and low-energy orbits, we conducted simulations to investigate the possibility of changing the orbit. We used the Impulse Excitation Diagram here, but supplemented it with multi-colored probability distribution maps illustrating the possibility of achieving a stable orbit at given numerical values of the impulse amplitude and duration for various values of air flow velocity. The use of probability distribution maps allow to select the optimal impulse characteristics from the point of view of the energy necessary for its initiation.

Abstract
Purpose
Risk stratification for incidence of major adverse cardiovascular events (MACE) in patients with dialysis-dependent end-stage renal disease (dd-ESRD) is challenging. Moreover, the usefulness of coronary CT angiography (CCTA) is often limited because of high calcification. This study aimed to investigate the prognostic value of comprehensive cardiac CT in patients with dd-ESRD for predicting MACE.

Materials and methods
This retrospective analysis included 92 patients with dd-ESRD who underwent comprehensive cardiac CT. Obstructive coronary artery disease (CAD) was defined by CCTA with > 50% stenosis. Global myocardial blood flow (MBF) and summed stress score (SSS) were obtained through dynamic CTP. Cox regression analysis was used to assess correlation with MACE. Kaplan–Meier curves were used to estimate cumulative event rates, and the global Chi-square test was used to assess the incremental value of dynamic CTP over CCTA.

Results
During a median follow-up of 2.3 years, 43 patients experienced MACE. Univariate analysis revealed that presence of obstructive CAD, higher SSS, and lower global MBF were significantly associated with increased risk of MACE. In multivariable analysis, lower global MBF and presence of obstructive CAD were independently associated with MACE (p = 0.02, and p = 0.04, respectively). CCTA and dynamic CTP combination had incremental value over CCTA alone for predicting MACE, respectively (global Chi-square score, 19.3 and 11.7, respectively).

Conclusion
Presence of obstructive CAD on CCTA and lower global MBF on dynamic CTP are independently associated with increased risk of MACE in patients with dd-ESRD. The addition of dynamic CTP to CCTA may improve risk stratification in this population.

Evaluation of landing procedures for a high-altitude platform with skid-type landing gear based on pilot-in-the-loop simulations
Authors: Hasan Yasim J. 
Published: November 2024

AbstractIn the context of the project HAP, the German Aerospace Center (DLR) is currently developing a solar-powered high-altitude platform. The underlying vehicle is a fixed-wing aircraft that is supposed to be stationed in the stratosphere for 30 days. Due to, among others, low achievable rates of descent, the use of skids as landing gear and its high susceptibility to wind, landing this aircraft is a very challenging task. Hence, it requires a landing procedure specifically tailored to the aircraft’s particularities. Furthermore, this procedure needs to be easy to follow by pilots especially in adverse atmospheric conditions. This paper deals with a pilot-in-the-loop simulation campaign conducted to assess a landing procedure developed for the high-altitude platform in earlier works. Within this campaign, the pilots are supposed to land the aircraft following this developed procedure in atmospheric turbulence conditions. In addition, they also land the aircraft following a second procedure, which is based on a conventional landing. In doing so, the altitude at which a flare is performed and/or the propellers are shut down is varied. Finally, the novel procedure’s overall feasibility from a piloting point of view and its potential to reduce the risks during landing are assessed. The results show that the procedure proves to reduce the risk of inadvertent ground contact of the aircraft payload compartment, which is associated with serious damage to aircraft structure and payload. However, since the novel procedure is challenging for the pilots, some improvements to the procedure are proposed.
Mini-open periacetabular cementoplasty for periacetabular bone metastasis: a report of two cases

Published: November 2024

AbstractBone metastasis in the periacetabular region usually causes severe pain and functional disability. Some surgical procedures, such as the Harrington surgery and percutaneous cementoplasty, have been reported as treatment options for periacetabular bone metastases with limited efficacy. The former is highly invasive, while the latter may not allow the injection of a sufficient amount of cement. Here we report two surgical cases using a new modified surgical method (mini-open periacetabular cementoplasty: MO-PAC) consisting of tumor curettage and cementoplasty through a small incision.

AbstractWe report the case of a 39-year-old man who presented with a history of generalized fatigue, nausea, subjective fever with rigors, and renal dysfunction after receiving infliximab (IFX) therapy for Crohn’s disease. A renal biopsy revealed acute tubulointerstitial nephritis (ATIN). After other causes of acute kidney injury were excluded, steroid therapy was initiated, his fever subsided, and kidney function improved. From this case report, infliximab could be a rare cause of elevated kidney function and that it should be not considered a completely safe treatment or disregarded as potential cause of ATIN.
Teleoperation in robot-assisted MIS with adaptive RCM via admittance control
Authors: Nasiri Ehsan , Sowrirajan Srikarran , Wang Long 
Published: November 2024

AbstractThis paper presents the development and assessment of a teleoperation framework for robot-assisted minimally invasive surgery (MIS). The framework leverages our novel integration of a previously developed adaptive remote center of motion (RCM) using admittance control. This framework operates within a redundancy resolution method specifically designed for the RCM constraint. We introduce a compact, low-cost, and modular custom-designed instrument module (IM) that ensures integration with the manipulator, featuring a force/torque sensor, a surgical instrument, and an actuation unit for driving the surgical instrument. The paper details the complete teleoperation framework, including the telemanipulation trajectory mapping, kinematic modelling, control strategy, and the integrated admittance controller. Finally, the system’s capability to perform various surgical tasks was demonstrated, including passing a thread through the rings, picking and placing objects, and trajectory tracking.
Noether’s theorems and conservation laws in magnetohydrodynamics and Chew–Goldberger–Low plasmas

Published: November 2024

AbstractThe ideal magnetohydrodynamic (MHD) equations and the ideal Chew–Goldberger–Low (CGL) plasma equations are studied using Lagrangian field theory methods. Action principles for the equations are developed and used to obtain conservation laws using Noether’s theorems. The Galilean group admitted by the equations leads to (i) energy, (ii) momentum, (iii) center of mass, and (iv) angular momentum conservation laws corresponding to the time translation, space translation, Galilean boosts, and rotational symmetries, respectively. The cross-helicity conservation law is a consequence of a fluid relabeling symmetry, and is local or non-local depending on whether the entropy gradient ($$\nabla S$$

∇
S

) is perpendicular to the magnetic field induction $$\textbf{B}$$
B
or otherwise. The point Lie symmetries of the MHD and CGL equations consist of Galilean transformations and scalings. Noether’s second theorem is used to derive a wave action conservation equation for a linear non-WKBJ Alfvén waves model for stellar winds. Recent symmetry group investigation of the Lagrangian MHD equations in two space dimensions are discussed.
Can large language models be sensitive to culture suicide risk assessment?
Authors: Levkovich Inbar , Shinan-Altman S. , Elyoseph Zohar 
Published: November 2024

AbstractSuicide remains a pressing global public health issue. Previous studies have shown the promise of Generative Intelligent (GenAI) Large Language Models (LLMs) in assessing suicide risk in relation to professionals. But the considerations and risk factors that the models use to assess the risk remain as a black box. This study investigates if ChatGPT-3.5 and ChatGPT-4 integrate cultural factors in assessing suicide risks (probability of suicidal ideation, potential for suicide attempt, likelihood of severe suicide attempt, and risk of mortality from a suicidal act) by vignette methodology. The vignettes examined were of individuals from Greece and South Korea, representing countries with low and high suicide rates, respectively. The contribution of this research is to examine risk assessment from an international perspective, as large language models are expected to provide culturally-tailored responses. However, there is a concern regarding cultural biases and racism, making this study crucial. In the evaluation conducted via ChatGPT-4, only the risks associated with a severe suicide attempt and potential mortality from a suicidal act were rated higher for the South Korean characters than for their Greek counterparts. Furthermore, only within the ChatGPT-4 framework was male gender identified as a significant risk factor, leading to a heightened risk evaluation across all variables. ChatGPT models exhibit significant sensitivity to cultural nuances. ChatGPT-4, in particular, offers increased sensitivity and reduced bias, highlighting the importance of gender differences in suicide risk assessment. The findings suggest that, while ChatGPT-4 demonstrates an improved ability to account for cultural and gender-related factors in suicide risk assessment, there remain areas for enhancement, particularly in ensuring comprehensive and unbiased risk evaluations across diverse populations. These results underscore the potential of GenAI models to aid culturally sensitive mental health assessments, yet they also emphasize the need for ongoing refinement to mitigate inherent biases and enhance their clinical utility.
Single-party regime, cooptation, and strategic social spending in developing countries
Authors: Zheng Li 
Published: November 2024

AbstractHow regime types affect the provision of social spending in the context of developing countries? This article provides a novel political-economic approach, arguing that single-party regimes are more likely to spend on pensions than other types of autocratic states to co-opt the large number of critical members although the regime type does not affect the general welfare spending across autocratic states. The theory emphasizes the effect of institutional and power structure heterogeneity across autocracies in shaping the incentives and strategies that the ruling elites co-opt and respond to the demands of the ruling coalition across different autocratic regimes. Using panel, ordinary least squares (OLS) regression with lagged dependent variable along with several empirical strategies, it finds the evidence supporting this argument with a new dataset from 1990 to 2012. The study provides new insights on how autocratic institutions especially the party utilize strategic social policies to resolve the elite-level dictator dilemma for regime survival that are absent in other autocratic types.
