Overlapping minds and the hedonic calculus
Authors: Roelofs Luke , Sebo Jeff 
Published: May 2024

AbstractIt may soon be possible for neurotechnology to connect two subjects' brains such that they share a single token mental state, such as a feeling of pleasure or displeasure. How will our moral frameworks have to adapt to accommodate this prospect? And if this sort of mental-state-sharing might already obtain in some cases, how should this possibility impact our moral thinking? This question turns out to be extremely challenging, because different examples generate different intuitions: If two subjects share very few mental states, then it seems that we should count the value of those states twice, but if they share very many mental states, then it seems that we should count the value of those statesonce. We suggest that these conflicting intuitions can be reconciled if the mental states that matter for welfare have a holistic character, in a way that is independently plausible. We close by drawing tentative conclusions about how we ought to think about the moral significance of shared mental states.
Efficiency in electricity distribution in Sweden and the effects of small-scale generation, electric vehicles and dynamic tariffs
Authors: Lundgren Tommy , Vesterberg Mattias 
Published: May 2024

AbstractWe measure the cost of technical inefficiency for local electricity distribution firms in Sweden using Stochastic Frontier Analysis, and explore how small-scale generation, the number of electric vehicles and the introduction of dynamic pricing schemes affects the transient inefficiency and efficiency scores. Our results show little to no effect of these environmental variables on the cost of technical inefficiency of electricity distribution grids in Sweden.
Efficiency analysis using SBM and PLS-SEM: insights from the Italian judicial system
Authors: Mazzocchi Paolo , Quintano Claudio , Rocca Antonella 
Published: May 2024

AbstractRecent governmental concerns regarding the persistent long duration of judicial proceedings have drawn attention to efficiency issues in this sector. This paper provides insights into the Italian scenario, investigating potential relationships between Italian judicial efficiency and several latent constructs identified as relatively more significant than others. For this purpose, a two-step procedure was used, considering data envelopment analysis (DEA), precisely the slacks-based measure (SBM), and partial least squares structural equation modeling (PLS-SEM). Beyond ranking courts according to their technical efficiency, findings reveal that judicial efficiency has significant relationships with performance, quality and context features. At the same time, results do not show evidence to support a relationship with proceeding features. What emerges from the work is that the analysis of heterogeneity seems to offer relevant evaluation leverage, and significant differences appear among Italian courts. These insights and the model provided would represent a useful analysis tool for specific policy assessments, supporting the evaluation of regulatory measures and structural reforms relevant to judicial administration.
Competitive effects of implicit auction on interconnectors: evidence from Japan
Authors: Sugimoto Kota 
Published: May 2024

AbstractInterconnectors play a crucial role in electric power systems. They contribute to balancing demand and supply in real-time, guaranteeing efficient dispatch in wide geographic regions, and increasing competition by creating large markets. However, interconnector capacity is a scarce resource because vertically integrated utilities were required to have generating capacity enough to supply most customers within their operating region under a regulated monopoly. Hence, identifying the efficient allocation method is essential, particularly after recent electricity market restructuring. This study evaluates the competitive effect of the implicit auction on the interconnector transmission capacity. The implicit auction allocates all the interconnector capacity simultaneously with electric energy in the day-ahead market. This method prevents market participants from strategically withholding the physical interconnector capacity ex ante to exercise market power, as allowed under the first come, first served rule. This study empirically shows how the capacity was withheld from the day-ahead market under the first come, first served rule using detailed reservation data. Next, I show that the implicit auction increases interconnector capacity available at the day-ahead market and trade volume. I use machine-learning methods, such as random forest and deep neural networks, to predict the counterfactual market outcomes without implicit auction. I find that the gain from trade under the implicit auction is more than US$55 million per year in Japan, which is more than 100 times the implementation cost of the implicit auction.
DICEguard: enhancing DICE security for IoT devices with periodic memory forensics
Authors: Yamak Yusuf , Tosun Suleyman , Aydos Murat 
Published: May 2024

AbstractThe number of Internet-of-Things (IoT) devices has been increasing rapidly every year. Most of these devices have access to important personal data such as health, daily activities, location, and finance. However, these devices have security problems since they have limited processing power and memory to implement complex security measures. Therefore, they possess weak authentication mechanisms and a lack of encryption. Additionally, there are no widely accepted standards for IoT security. Device Identifier Composition Engine (DICE) was proposed as a standard that enables adding a security layer to low-cost microcontrollers with minimal silicon overhead. However, previous studies show that DICE-based attestation is vulnerable to some remote attacks. In this study, we present a novel method called DICEguard to address the security problems of DICE. One of the key innovations of DICEguard is its incorporation of periodic memory forensics (PMF) technique, leveraging a hardware-based hash engine to detect and mitigate potential security breaches resulting from firmware vulnerabilities. DICEguard enhances the overall resilience of IoT devices against attacks by swiftly detecting alterations indicative of malicious activity through periodic calculation and comparison of firmware digests. Furthermore, DICEguard introduces a one-time programmable (OTP) memory component to safeguard critical security parameters, such as public keys used for signature verification, against tampering by adversaries. This ensures the integrity of essential security measures even in the face of sophisticated attacks. We implemented the enhanced DICE architecture using the open-source RISC-V platform Ibex and the mbedTLS library for cryptographic operations. We performed the hash operations required by DICE in a hardware-based manner on a commercial Field Programmable Gate Array (FPGA) platform rather than firmware, which is more vulnerable to attacks. Our test results show that with negligible area overhead to a standard microcontroller system, the proposed method can detect the simulated attacks.

Published: May 2024

AbstractMathematical models may aid researchers in describing biological processes, like growth, in animals. This study aimed to collect the body weight data of 18 Boer goat castrates and 20 Boer goat does, from birth until maturity, to model growth and determine growth trends. This is a novel investigation as sufficient information on an age-weight database for these two Boer goat sexes from birth to maturity, is lacking. Using age-weight data, four nonlinear models, namely the Brody, Gompertz, Logistic and Von Bertalanffy growth models, were plotted and evaluated. The model parameters of each growth model were compared for differences between the two sexes. The statistical effectiveness of fit was determined for each model using AIC and RMSE, with R2 also being considered. All models except the Brody model, predicted significantly heavier mature weights for castrates. The Brody model was deemed unfit to describe Boer goat growth as the function severely over-predict weights from birth until maturity for both sexes. The Von Bertalanffy (R2 = 91.3) and Gompertz functions (R2 = 91.3) showed the best fit for Boer goat castrates, while the Gompertz model (R2 = 95.1) showed the best fit for Boer goat does. The Gompertz function is the preferred model to depict Boer goat growth overall, as it accurately characterized growth of both sexes. According to the Gompertz model the age at which the inflection point of the growth curve was reached, did not differ significantly between castrates and does (141.80 days versus 136.31 days). There was also no significant difference in maturation rate between the two sexes.

Abstract
Background
This study aimed to investigate the role of uric acid (UA) in diabetic nephropathy (DN) from epidemiological and genetic perspectives.

Methods
We used data from the 2007–2016 National Health and Nutrition Examination Survey to evaluate the relationship between UA and DN risk using weighted multivariate-adjusted logistic regression. Subsequently, a two-sample Mendelian randomization study was conducted using genome-wide association study summary statistics. The main inverse variance weighting (IVW) method and supplementary MR method were used to verify the causal relationship between UA and DN, and sensitivity analysis was conducted to confirm the credibility of the results.

Results
Our observational study enrolled 4363 participants with diabetes mellitus from NHANES, among them, 2682 (61.4%) participants were identified as DN. The multivariate logistic regression model showed that compared with those without hyperuricemia, the DN risk of the hyperuricemia population was significantly increased (P < 0.05). The MR results suggest a direct causal effect of hyperuricemia on DN (IVW odds ratio (OR): 1.37 (95% confidence interval 1.07–1.76); P = 0.01), which is consistent with findings from other MR methods.

Conclusion
The evidence from observational studies indicates a positive correlation between HUA and the onset of DN. And the causal effects of HUA on DN were supported by the MR analysis.
Physically based vs. data-driven models for streamflow and reservoir volume prediction at a data-scarce semi-arid basin
Authors: Özdoğan-Sarıkoç Gülhan , Dadaser-Celik Filiz 
Published: May 2024

AbstractPhysically based or data-driven models can be used for understanding basinwide hydrological processes and creating predictions for future conditions. Physically based models use physical laws and principles to represent hydrological processes. In contrast, data-driven models focus on input–output relationships. Although both approaches have found applications in hydrology, studies that compare these approaches are still limited for data-scarce, semi-arid basins with altered hydrological regimes. This study aims to compare the performances of a physically based model (Soil and Water Assessment Tool (SWAT)) and a data-driven model (Nonlinear AutoRegressive eXogenous model (NARX)) for reservoir volume and streamflow prediction in a data-scarce semi-arid region. The study was conducted in the Tersakan Basin, a semi-arid agricultural basin in Türkiye, where the basin hydrology was significantly altered due to reservoirs (Ladik and Yedikir Reservoir) constructed for irrigation purposes. The models were calibrated and validated for streamflow and reservoir volumes. The results show that (1) NARX performed better in the prediction of water volumes of Ladik and Yedikir Reservoirs and streamflow at the basin outlet than SWAT (2). The SWAT and NARX models both provided the best performance when predicting water volumes at the Ladik reservoir. Both models provided the second best performance during the prediction of water volumes at the Yedikir reservoir. The model performances were the lowest for prediction of streamflow at the basin outlet (3). Comparison of physically based and data-driven models is challenging due to their different characteristics and input data requirements. In this study, the data-driven model provided higher performance than the physically based model. However, input data used for establishing the physically based model had several uncertainties, which may be responsible for the lower performance. Data-driven models can provide alternatives to physically-based models under data-scarce conditions.

Published: May 2024

AbstractEntoloma is one of the largest genera of Agaricales in terms of species diversity and is widespread throughout the world. In the present study, four new species, namely Entoloma brunneofibrillosum, E. humidiphilum, E. ochraceodiscum, and E. colchicum, are introduced as new to science. These species are described based on specimens collected in Cyprus, Georgia, Hungary, Italy, Russia, Spain, and Türkiye, including morphological characteristics and phylogenetic analyses of the nuclear ribosomal DNA internal transcribed spacer (ITS) sequences. Entoloma brunneofibrillosum is recognized by its brown to dark brown pileus with conspicuous dark, radial fibrils, a pale brown stipe with glistening fibrils, and usually fusiform to broadly clavate cheilocystidia. It belongs to the /Undulatosporum clade. Entoloma humidiphilum (subg. Alboleptonia) is close to E. niveum from New Zealand but differs by a completely pruinose or minutely squamulose pileus surface, narrowly cylindrical to cylindrical pileipellis elements with a deep median constriction, and by occurring in riparian habitats. Entoloma ochraceodiscum is characterized by funnel-shaped basidiomata with a deeply depressed yellowish-brown pileus and belongs to the section Griseorubida. Entoloma colchicum (subg. Nolanea) is similar to E. ortonii but differs by its distinctive radially fibrillose or velutinous pileus and the absence of odour. The new species are presented with photographs, line drawings, and comparisons with similar taxa.

Studying efficacy of particular design elements in online teacher professional development courses: The case of systematizing videos for enhancing teachers’ pedagogical content knowledge
Authors: Wischgoll Anke , Prediger Susanne 
Published: May 2024

AbstractWhile design principles for effective teacher professional development (PD) courses have been empirically identified in comprehensive studies, they have not yet been well disentangled with respect to the contribution of specific design elements. This particularly applies for digital online PD courses and for teachers with different prior knowledge. In this paper, we investigate two design elements for the systematizing phase (videos vs. discussions) of a synchronous online PD session with regard to their differential effectiveness for teachers’ professional growth in pedagogical content knowledge (PCK) and their emotional and motivational reactions to the PD. In our focused randomized controlled trial, 102 mathematics teachers (with heterogeneous PCK) participated in 2‑hour online PD sessions on specifying, noticing, and enhancing students’ understanding of multiplication with various PD inquiry activities. In the systematization phase, teachers were randomly assigned to two treatment conditions: the video group watched a systematizing video (i.e., a video that summarizes the PCK elaborated during the session) and the discussion group had small-group discussions about individual summaries. In both groups, teachers’ reports about emotional and motivational reactions to the PD revealed similarly high values, and their PCK improved significantly from pre-test to post-test. Analyses of variance with repeated measures revealed significant differences between the treatment conditions for teachers with low prior PCK: Teachers with low prior PCK who watched the systematizing video developed their PCK significantly more than those who discussed in small groups. In this way, the study contributes to disentangling the differential effects of design elements in online PD courses for teachers with heterogeneous prior knowledge.

AbstractThe influence of anatomical parameters on urinary continence (UC) after Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) remains uncharted. Our objective was to evaluate their association with UC at 3, 6 and 12 months post-operatively. Data from patients who underwent RS-RARP were prospectively collected. Continence was defined as no pad use. Anatomic variables were measured on preoperative magnetic resonance imaging (MRI). Regression analyses were performed to identify predictors of UC at each time point. We included 158 patients with a median age of 60 years, most of whom had a localized tumor (≤ cT2). On multivariate analyses, at 3 months post-surgery, urinary incontinence (UI) rises with age, odds ratio (OR) 1.07 [95% confidence interval (CI) 1.004−1.142] and with prostate volume (PV), OR 1.029 (95% CI 1.006−1.052); it reduces with longer membranous urethral length (MUL), OR 0.875 (95% CI 0.780−0.983) and with higher membranous urethral volume (MUV), OR 0.299 (95% CI 0.121−0.737). At 6 months, UI rises with PV, OR 1.033 (95% CI 1.011−1.056) and decreases with MUV, OR 0.1504 (95% CI 0.050−0.444). Significantly, at 12 months post-surgery, the only predictor of UI is MUL, OR 0.830 (95% CI 0.706−0.975), establishing a threshold associated with a risk of UI of 5% (MUL > 15 mm) in opposition to a risk of 25% (MUL < 10 mm). This single institutional study requires external validation. To our knowledge, this is the first prospective cohort study supporting MUL as the single independent predictor of UC at 12 months post-surgery. By establishing MUL thresholds, we enable precise patient counseling.

Published: May 2024

AbstractDue to increasing demands regarding higher manufacturing accuracy and the machining of high-strength materials, the stiffness and load-carrying capacity of main spindles must be enhanced. One approach is to replace the conventionally used angular contact ball bearings, so called spindle bearings, with tapered roller bearings of the same size, which have a higher stiffness and load carrying capacity due to their larger rolling contact. In case the speed requirement is below a speed parameter $$n\cdot d_{m}=0.9\times 10^{6}$$

mm/min, the poorer speed parameter of tapered roller bearings can be compensated by a sufficiently high lubrication quantity. However, the stiffness increase by using this bearing type in main spindles has not yet been quantified in field tests. Therefore, the aim of this paper is to demonstrate the stiffness advantage of a spindle with an elastically arranged tapered roller bearing compared to a conventional spindle with angular contact ball bearings by machining tests. First, the radial load displacement characteristic of the newly developed tapered roller bearing spindle is tested in advance on an isolated test rig. In machine cutting tests, full slots are milled in an aluminum block. During the tests, the axial and radial displacements of the spindle shaft relative to the housing are measured and evaluated in radial and axial direction. These tests are repeated and compared with the conventional spindle. By varying the process parameters such as cutting depth, feed rate or rotational speed, the increased stiffness of the tapered roller bearing spindle compared to the conventional spindle is illustrated based on the measured displacements. Moreover, frequency response measurements at different speeds underpin the improved damping of the tapered roller bearing spindle. Assuming that the speed requirements are not too high and the tapered roller bearing is sufficiently lubricated, the use of this type of bearing can significantly increase the stiffness and thus the manufacturing precision in the long term for main spindles.
Understanding the onto-semiotic approach in mathematics education through the lens of the cultural historical activity theory
Authors: Godino Juan D. , Batanero Carmen , Burgos María , Wilhelmi Miguel. R. 
Published: May 2024

AbstractResearch in mathematics education can be understood as a system of activities addressing the basic and applied problems related to teaching and learning of mathematics. Such a system includes the activities of foundation, planning, implementation, evaluation of mathematics instruction, and teacher professional development, which are supported by different theories. This diversity of theories raises interest in their comparison, coordination, and possible integration. The paper aims to present a case of application of the Cultural Historical Activity Theory (CHAT), in its 3rd and 4th generation versions, to analyze the emergence of the Onto-semiotic Approach to mathematical knowledge and instruction as a theoretical framework that addresses the study of the five partial activities mentioned above. This use of the CHAT can be useful in studies on theory articulation by focusing not only on the subjects, the object, and the instruments but also on the community context, the ecological-normative environment in which these activities take place, and the dilemmas or contradictions between theories.
