Published: November 2024

Abstract
Purpose
Revisional bariatric surgery (RBS) has flourished during the last decades in many countries, due to suboptimal weight loss or long-term complications of primary bariatric surgery. Restrictive procedures, and in particular sleeve gastrectomy (SG), although widely performed as primary bariatric surgery, seems particularly prone to need surgical revision for the above-mentioned reasons during long-term follow-up. The aim of this systematic review was to compare the long-term (5-year) safety and efficacy between Roux-en-Y gastric bypass (RYGB) and single anastomosis duodeno-ileal bypass (SADI) after ‘failed’ SG.

Methods
A systematic review was performed from 2007 to September 2024. Articles were included if SADI or RYGB were performed as RBS after ‘failed SG’ with follow-up at least 5 years. Pooled analysis was performed to summarize the data.

Results
Among the seven studies eligible and included in this review, the SADI procedure showed comparable results to RYGB in terms of weight loss, nutritional deficiencies, and resolution of comorbidities during the long-term follow-up. However, RYGB proved superior in terms of remission of reflux disease and other functional problems after SG.

Conclusions
The present review found that SADI seems to be a promising and suitable method for suboptimal weight loss after SG, with comparable or even better results to RYGB after 5-year follow-up.
A comparison of formulations and non-linear solvers for computational modelling of semiconductor devices
Authors: Pérez-Escudero Sergi , Codony David , Arias Irene , Fernández-Méndez Sonia 
Published: November 2024

AbstractThe drift-diffusion formulation, modelling semiconductor materials in terms of carrier densities and electric potential, is considered together with an alternative formulation in terms of dimensionless logarithmic quantities. Stability of both formulations in presence of sharp variations with a Galerkin Finite Element discretisation is assessed in two realistic problems: a p-n junction and an n-MOSFET device. The robustness with respect to the initial guess and the computational efficiency of the Newton-Raphson and Gummel non-linear solvers are also compared.

Abstract
Background
Isotonic fluids are becoming the standard for hydration and maintenance fluid therapy, but there is no consensus on the optional choice among the different types of isotonic solution.

Methods
This study is a single-center, non-randomized controlled trial at Kobe University Hospital, Japan, between April 2021 and March 2023. The study included pediatric patients aged 1–19 years who underwent kidney biopsies. From April 2021 to March 2022, 0.9% sodium chloride (saline) was administered, and from April 2022 to March 2023, balanced crystalloids were used. The primary outcome was the occurrence of hyponatremia (< 137 mEq/L) after a kidney biopsy. Secondary outcomes included other electrolyte balances, blood gas parameters, creatinine-based estimated glomerular filtration rate (Cr-eGFR), and arginine vasopressin concentrations (UMIN Clinical Trial Registry: UMIN 000044330).

Results
Of 61 patients enrolled, 2 were excluded, leaving 34 in the saline group and 25 in the balanced crystalloid group. No hyponatremia occurred, and serum sodium concentrations were similar between both groups (138.7 vs. 138.9 mEq/L, P = 0.08). The saline group showed a greater increase in serum chloride (+ 1.7 vs. + 0.2, P < 0.01) and a greater decrease in HCO3− concentrations (− 0.6 vs. + 0.9, P < 0.01). There were minimal changes in pH (− 0.01 vs. − 0.01, P = 0.99) and Cr-eGFR (− 1.5 vs. + 1.1 mL/min/1.73 m2, P = 0.96) in both groups.

Conclusions
During pediatric kidney biopsy, both saline and balanced crystalloids were effective in preventing hyponatremia. Although saline infusion results in higher serum chloride concentrations and lower blood HCO3− concentrations than balanced crystalloids infusion, the clinical significance was minimal.

Application of stochastic storm transposition for hydrologic modeling in the mountainous western US
Authors: Lawler Seth , Deshotel Matthew , Dietrich Alyssa Hendricks , Zhang Lan , Karlovits Gregory , Ferreira Celso 
Published: November 2024

Abstract
Recent studies have shown that stochastic storm transposition (SST) is an effective method for flood frequency analysis in small to medium sized watersheds. The effectiveness of this method has not been evaluated in larger watersheds in mountainous regions where snowmelt is the primary driver for peak flow events. In the western United States, several watersheds fall in an area where NOAA Atlas-14 precipitation frequency estimates do not exist. This data sparsity limits the available methods for developing flood frequency estimates. In this research, we present a case study for exploring the use of SST in the high desert of Wyoming, with challenges of scale, regulation, and snowmelt. Building on existing methods, a framework for performing SST in cold mountain regions is proposed, including incorporation of snowmelt functions, normalization fields in high altitude locations, and techniques for hydrologic model adjustment to account for epistemic uncertainty due to regulation. Results show that the foundational processes in the SST framework provide a valuable alternative for peak flow analysis in locations where frequency-based precipitation is not available.

Macroeconomic performance of European Union's small open economies during the COVID-19 pandemic
Authors: Szomolanyi Karol , Lukacik Martin , Lukacikova Adriana 
Published: November 2024

AbstractThis paper explains the business cycle characteristics in the small open European Union Countries during the COVID-19 pandemic. The panel cyclical components of GDP and its components, labour, and average product of labour were computed. The study adopts a real business cycle model with importable, exportable, and tradeable products to explain the cyclical characteristics of small and big EU countries. According to the results, the business cycle characteristics of the big EU countries during the pandemic correspond to the findings from the papers worldwide. The primary shock was a decrease in the labour supply. An increase in the adjustment capital costs explains the unusual consumption volatility. Results related to the small EU countries differ from those of the big countries and those obtained in other studies. The primary source of macroeconomic changes during the pandemic was changes in the terms of trade. Changes in the labour supply were also significant. The higher capital adjustment costs explain the consumption volatility, and the higher debt service costs explain the investment volatility.
Regional variation in the utilization of nursing home care in Germany
Authors: Herr Annika , Lückemann Maximilian , Saric-Babin Amela 
Published: November 2024

AbstractApproximately 32 percent of individuals aged over 64 years old, with care needs, are residing in nursing homes in Germany. However, this percentage exhibits significant regional disparities, ranging from under 15 percent in certain counties to over 50 percent in others. The purpose of this study is to elucidate the underlying factors explaining this regional variation in nursing home utilization. We employed comprehensive administrative data encompassing the entire elderly care-dependent population and all nursing homes. Our analytical approach involves the use of linear regression models at the county level, accounting for an extensive array of control variables and fixed effects. Additionally, we analyzed regional dependencies by applying spatial lag models. In summary, our model successfully predicts up to 73 percent of the observed regional variation in nursing home utilization. Key factors include care needs, the presence of informal care support and the supply of professional care. Spatial dependencies can be detected but exhibit a minor influence on these variations controlling for care needs. Noteworthy, enabling factors, such as a region’s wealth or rurality, have a very limited impact in a country with a generous social insurance system that covers care for those with limited financial resources.

Abstract

Purpose
Early detection and quantitative evaluation of liver steatosis are crucial. Therefore, this study investigated a method for classifying ultrasound images to fatty liver grades based on echo-envelope statistics (ES) and convolutional neural network (CNN) analyses.

Methods
Three fatty liver grades, i.e., normal, mild, and moderate-to-severe, were defined using the thresholds of the magnetic resonance imaging-derived proton density fat fraction (MRI-PDFF). There were 10 cases of each grade, totaling 30 cases. To visualize the texture information affected by the deposition of fat droplets within the liver, the maps of first- and fourth-order moments and the heat maps formed from both moments were employed as parametric images derived from the ES. Several dozen to hundreds of regions of interest (ROIs) were extracted from the liver region in each parametric image. A total of 7680 ROIs were utilized for the transfer learning of a pretrained VGG-16 and classified using the transfer-learned VGG-16.

Results
The classification accuracies of the ROIs in all types of the parametric images were approximately 46%. The fatty liver grade for each case was determined by hard voting on the classified ROIs within the case. In the case of the fourth-order moment maps, the classification accuracy of the cases through hard voting mostly increased to approximately 63%.

Conclusions
The formation of parametric images derived from the ES and the CNN classification of the parametric images were proposed for the quantitative diagnosis of liver steatosis. In more than 60% of the cases, the fatty liver grade could be estimated solely using ultrasound images.
Discontinuous Galerkin schemes for Stokes flow with Tresca boundary condition: iterative a posteriori error analysis
Authors: Djoko J.K. , Sayah T. 
Published: November 2024

AbstractIn two dimensions, we propose and analyse an iterative a posteriori error indicator for the discontinuous Galerkin finite element approximations of the Stokes equations under boundary conditions of friction type. Two sources of error are identified here, namely; the discretisation error and the linearization error. Under a smallness assumption on data, we prove that the devised error estimator is reliable. Balancing these two errors is crucial to design an adaptive strategy for mesh refinement. We illustrate the theory with some representative numerical examples.
Aggregating bipolar opinions through bipolar assumption-based argumentation
Authors: Dickie Charles , Lauren Stefan , Belardinelli Francesco , Rago Antonio , Toni Francesca 
Published: November 2024

AbstractWe introduce a novel method to aggregate bipolar argumentation frameworks expressing opinions of different parties in debates. We use Bipolar Assumption-based Argumentation (ABA) as an all-encompassing formalism for bipolar argumentation under different semantics. By leveraging on recent results on judgement aggregation in social choice theory, we prove several preservation results for relevant properties of bipolar ABA using quota and oligarchic rules. Specifically, we prove (positive and negative) results about the preservation of conflict-free, closed, admissible, preferred, complete, set-stable, well-founded and ideal extensions in bipolar ABA, as well as the preservation of acceptability, acyclicity and coherence for individual assumptions. Finally, we illustrate our methodology and results in the context of a case study on opinion aggregation for the treatment of long COVID patients.

Direct loss-based seismic retrofit of reinforced concrete frames
Authors: Rubini Giorgio , Calvi Gian Michele , Gentile Roberto 
Published: November 2024

Abstract
In earthquake-prone areas, structures not compliant with modern design codes significantly contribute to seismic risk. Therefore, risk mitigation strategies (e.g., seismic retrofit) should be employed to reduce the expected economic and human losses. This paper introduces a procedure for the design of retrofit solutions for reinforced concrete (RC) frame buildings to achieve - rather than be bounded by - a desired target level of earthquake-induced loss for a given site-specific seismic hazard profile. The presented methodology is “direct” because the designer and/or client can set a loss target in the first step of the procedure and no design iterations are virtually required. Direct loss-based seismic retrofit (DLBR) relies on a simplified loss assessment methodology enabled by a surrogate probabilistic seismic demand model. This defines the probability distribution of seismic deformation demand of single degree of freedom (SDoF) systems conditioned on different shaking intensity levels. The proposed design methodology enables designers to account for risk/loss-based considerations from the conceptual/preliminary design phase, thus facilitating the choice among different retrofit solutions. Starting from two under-designed case-study buildings, four illustrative applications of the procedure are provided. They involve considering different economic expected annual loss targets and different retrofit solutions involving the addition of RC walls and RC column jacketing. Benchmark loss estimates are calculated using non-linear time-history analyses of refined, multi-degree-of-freedom models showing satisfactory results: the simplified loss estimate introduces an overestimation maximum equal to 15.4% among the four illustrative applications.
Refashioning Second-Hand Clothes Consumption Through Pleasure, Pain, Seduction and Conversion: A Virtue Ethics Perspective
Authors: Auxtova Kristina , Schreven Stephanie , Wishart Lucy J. 
Published: November 2024

Abstract
The fashion industry needs to become more circular, given the unsustainable levels of waste it produces. Our research empirically explores and theoretically develops how adopting a virtue ethics approach can encourage and support second-hand clothing consumption as a form of reuse and a way of practicing sustainability. Based on ethnographic interviews with consumers who shop in UK charity shops, our grounded theory study focuses on how consumers experience second-hand clothing consumption as constitutive of sources of (in)action that encourage or inhibit virtuous, sustainable behaviour. We find that pleasure and/or shame or guilt (pain) are key to enabling virtuous moral decision-making towards reuse and sustainability. We furthermore argue that seduction and conversion, hand in hand with pleasure, act as levers supporting such moral decision-making, mitigating aversions and wayward desires that obstruct good moral intentions to consume second-hand clothing. By engaging empirically with moral decision-making, our research theoretically advances scholarship on virtue ethics and second-hand clothing consumption, whilst contributing to an ethically informed vision of the circular economy. We conclude with implications for charity retail practices in support of circularity and sustainability informed by a virtue ethics perspective, as well as suggestions for future research.
Learning and fine-tuning a generic value-selection heuristic inside a constraint programming solver

Published: November 2024

Abstract
Constraint programming is known for being an efficient approach to solving combinatorial problems. Important design choices in a solver are the branching heuristics, designed to lead the search to the best solutions in a minimum amount of time. However, developing these heuristics is a time-consuming process that requires problem-specific expertise. This observation has motivated many efforts to use machine learning to automatically learn efficient heuristics without expert intervention. Although several generic variable-selection heuristics are available in the literature, the options for value-selection heuristics are more scarce. We propose to tackle this issue by introducing a generic learning procedure that can be used to obtain a value-selection heuristic inside a constraint programming solver. This has been achieved thanks to the combination of a deep Q-learning algorithm, a tailored reward signal, and a heterogeneous graph neural network. Experiments on graph coloring, maximum independent set, maximum cut, and minimum vertex cover problems show that this framework competes with the well-known impact-based and activity-based search heuristics and can find solutions close to optimality without requiring a large number of backtracks. Additionally, we observe that fine-tuning a model with a different problem class can accelerate the learning process.
Intertwined precarities: how can vulnerability create a labor relationship?
Authors: Vigvári András , Németh Krisztina 
Published: November 2024

AbstractThrough a micro-case study of labor relation within a small Hungarian horticulture enterprise, our study reveals what precarity means and what experiences it entails for a small-farmer employer and his workers. Drawing on theoretical works that emphasize relationality and the multifaceted character of precarity, we can delineate the different constellations of vulnerabilities, dependency, and autonomy in different social positions. Precarity covers a wide range of social situations and experiences. In contrast to previous research, which emphasize the challenges that the heterogeneity of precarious situations pose for class formation, we highlight the ways the experience of precarity may become the basis of solidarity. Instead of scrutinizing only the employee’s precarity, which is common in research, we focus on its relationality. Our micro-case study examines the ways precarity interlinks the employer and the employee despite their different social positions and the potential conflict of interest between them. Our analysis shows that the intertwined (shared but differently experienced) precarity can create a labor relation, which is based on the recognition of each party’s vulnerabilities and mutual dependence between employer and employee. Both parties provide each other with some stability and describe this labor relation with the notion of “family,” which demonstrates the possibilities and the limits of this form of solidarity. Yet, the vulnerabilities of both parties also expose the fragility of this labor relation.
When Moral Pleasure Conflicts with Moral Sorrow
Authors: Rawat Drishtti 
Published: November 2024

AbstractIn this paper, I discuss two of Aristotle’s major requirements for the virtuous person. First, the virtuous person takes pleasure in virtuous activity. Second, the virtuous person experiences the appropriate affective states in the appropriate situations. However, in some situations, the appropriate affective state is sorrow. In such situations, it appears that the virtuous person is expected to experience two conflicting emotions, namely, moral pleasure and moral sorrow. This conflict raises the deeper concern that the virtuous person has conflicting values and leads critics to reject Aristotle’s requirement of moral pleasure. I argue that critics need not take such measures because the conflict in the virtuous person’s values is merely apparent. I do this by first considering potential solutions, including an appeal to a de dicto interpretation of moral pleasure, and discussing how they prove unsatisfactory. Then, I recommend a desire-based understanding of moral pleasure and analyse the values underlying it. Through this analysis, I reveal that the virtuous person’s moral pleasure and moral sorrow indicate the same kind of value to the same objects of concern. And, because the virtuous person’s moral sorrow indicates the same value for virtuous activity, I conclude that it is necessary for a person to be able to experience moral pleasure and to be considered a virtuous person in the first place.
