Published: November 2024

AbstractSitus viscerum inversus totalis (SIT) is a rare congenital anomaly. Deceased donors with this condition are often declined because of the technical issues in both the organ’s procurement and its transplant. Only eight cases of deceased donor organs with SIT were reported to be used for liver transplantation (LT). We herein present a case of LT using a graft from an SIT donor: a modified retroversus piggyback technique was used. A 15 year-old female was referred to our institution as a potential donor. An SIT condition was discovered during standard donor evaluation together with the presence of a complex triple arterial pedicle. Procurement operative time was 125 min, from skin incision to cross-clamp. Liver extraction occurred 32 min after cold flush. The recipient was a 56 year-old male affected by recurrent hepatocellular carcinoma (HCC) on hepatitis C related liver cirrhosis. Position and orientation trials of the graft were made and it was decided to implant it with the retroversus technique. Direct duct-to-duct biliary reconstruction was achieved. The postoperative course was uneventful. To our knowledge, this is the first implant with retroversus technique combined to direct biliary reconstruction and the first repetition of that technique. Cases like this highlight how technical complexity can be overcome leading to successful management of difficult scenarios in a safe manner.

Abstract
Nanosized materials are increasingly being recognized as inherent components in the development of energy storage devices and other state-of-the-art dielectric applications. In this work, nickel oxide (NiO), cobalt oxide (Co3O4) and NiO–Co3O4 nanocomposites in different compositions (10%, 20%, 30% and 40%) were successfully synthesized through hydrothermal method, optimizing concentrations of the precursors, and X-ray diffraction confirmed single-phase polycrystalline NiO and Co3O4. SEM images showed that distinct morphologies for each material and FTIR spectra reveal Ni–O and Co–O. UV–visible analysis shows a plasmon peak at 307 nm for NiO and excition absorption at 282 nm for Co3O4. NiO–Co3O4 nanocomposites displayed band gaps ranging from 2.37 eV to 2.67 eV. Dielectric properties showed a decrease in εʹ with frequency, attributed to Maxwell–Wagner and hopping models. AC conductivity increased with frequency due to Co3O4 content and oxygen vacancies. The study suggests potential applications in supercapacitors, spintronics, high-frequency devices and ultra-high dielectric materials.
Welche Rolle spielen kognitive Belastung und Motivation beim feedbackgestützten Lernen?
Authors: Boegel Svenja , Ropohl Mathias 
Published: November 2024

ZusammenfassungSchüler:innen zeigen Schwierigkeiten bei der Planung von naturwissenschaftlichen Experimenten unter Anwendung der Variablenkontrollstrategie (VKS). Individuelles Feedback kann Schüler:innen bei der Anwendung der VKS unterstützen. Damit Feedback lernwirksam eingesetzt werden kann, ist Wissen über die gestalterische und inhaltliche Aufbereitung und deren Einfluss auf die Wirkung notwendig. Im Rahmen von Meta-Analysen und Interventionsstudien wurden Merkmale – sowohl gestalterische wie auch inhaltliche – analysiert und ihre Wirkung auf Wissen und Kompetenzen beim Anwenden der VKS belegt. Ob bestimmte Feedbackmerkmale dabei auch Einfluss auf die kognitive Belastung, Motivation und wahrgenommene Kompetenzunterstützung nehmen und so die Wirkung zusätzlich fördern können, gilt als offen. Vor diesem Hintergrund ist das Ziel der im vorliegenden Beitrag vorgestellten experimentellen Untersuchung gestalterische und inhaltliche Feedbackmerkmale sowie den Einfluss von Feedback auf die kognitive Belastung, Motivation und wahrgenommene Kompetenzunterstützung von Schüler:innen zu untersuchen. Hierzu wurden in drei Untersuchungsgruppen je eine andere Feedbackform – sachliches, motivierendes oder graphisches Feedback – im Chemieunterricht an Gymnasien (N = 98) eingesetzt. Die Ergebnisse zeigen, dass sich anhand der erhobenen Daten die untersuchten Feedbackmerkmale hypothesenkonform in gestalterische und inhaltliche Merkmale kategorisieren lassen, welche die formalen Kriterien sowie die Art der rückgemeldeten Informationen des Feedbacks widerspiegeln. Zu den gestalterischen Merkmalen zählen beispielsweise der Umfang von Feedback und ein klarer Bezug zur bearbeiteten Aufgabe. Das Rückmelden von Informationen zum Lernziel, Lernstand und den nächsten Lernschritten kann den inhaltlichen Merkmalen zugeordnet werden. Die genannten gestalterischen und inhaltlichen Merkmale haben einen signifikanten Einfluss auf die kognitive Belastung, die Motivation und die Kompetenzunterstützung von Schüler:innen beim Planen von Experimenten unter Anwendung der VKS. Jedoch führt der jeweilige gestalterische Schwerpunkt der drei Feedbackformen nicht zu wahrnehmbar unterschiedlichen Formen, da das Feedback selbst keinen Einfluss auf kognitive Belastung, Motivation und wahrgenommene Kompetenzunterstützung von Schüler:innen nimmt. Anhand der untersuchten Merkmale kann zukünftig Feedback generiert werden, das Schüler:innen noch besser hilft in Experimenten die VKS anzuwenden.
Phrasal frequency and literacy as predictors of individual differences in on-line processing and comprehension of English complex NP subject-verb agreement
Authors: Patterson Kinga , Street James A. , Myachykov Andriy 
Published: November 2024

AbstractWe present experimental evidence suggesting that frequency and literacy predict online processing and comprehension of subject-verb agreement constructions by adult native speakers of English. We measured participants’ eye fixations, reaction times, and response accuracy in a forced-choice task using audio-visual eye-tracking paradigm. Participants completed a battery of tasks, inc. the Literacy Rating Scale (Tarone et al., Literacy and Second Language Oracy-Oxford Applied Linguistics, Oxford University Press, 2013), Agreement Judgement Task (e.g., Veenstra et al., Frontiers in Psychology 5:783, 2014). The AJT involved matching an auditorily presented subject phrase to one of two images of easily distinguishable colours presented on a computer screen (e.g., stars, circles). Participants heard 42 test sentences, counterbalanced across the three types: Type 1 (e.g., ‘The stars with the circles are blue’), Type 2 (e.g., ‘The star with the circles is blue’) and Type 3 (e.g., ‘The star with the circles are blue’*. Type 1 and Type 2 constructions are considerably more frequent in writing than in speech (Miller et al., Spontaneous spoken language: Syntax and discourse, Oxford University Press on Demand, 1998) with Type 2 producing more attraction errors (Bock et al., Cognitive Psychology 43:83–128, 2001; Becker, L., & Dąbrowska, E. (2020). Does experience with written language influence grammaticality intuitions? UK Cognitive Linguistics Conference: University of Birmingham [conference presentation].). Data were analysed with linear mixed effects models and generalised additive models. Results show lower literacy participants took longer to process sentential cues and made more attraction errors. These findings support usage-based research showing frequency and experience effects on online comprehension of canonical and non-canonical constructions (Farmer, T. A., Misyak, J. B., & Christiansen, M. H. (2012). Individual differences in sentence processing. In Cambridge handbook of psycholinguistics (pp. 353-364)., Street, Language Sciences 59:192–203, 2017), detection and production of agreement attraction errors (Becker, L., & Dąbrowska, E. (2020). Does experience with written language influence grammaticality intuitions? UK Cognitive Linguistics Conference: University of Birmingham [conference presentation].) and demonstrate how linguistic and attentional processes interact (Tomlin and Myachykov, Attention and salience, Handbook of Cognitive Linguistics, 2015). They also complement corpus-based studies by providing evidence that native speakers are sensitive to observed distributions (Miller et al., Spontaneous spoken language: Syntax and discourse, Oxford University Press on Demand, 1998).
An Analysis of the Food and Drug Administration Manufacturer and User Facility Device Experience Database for MAGnetic Expansion Control Spinal Rods
Authors: Filan Jack , Bowey Andrew , Joyce Thomas 
Published: November 2024

Abstract
Background
MAGnetic Expansion Control (MAGEC) rods can prevent repeated lengthening operations for scoliosis patients. However, there have been several Field Safety Notices issued, including a worldwide product recall due to actuator endcap separation. We aimed to review adverse events reported to the Food and Drug Administration (FDA) regarding MAGEC rods, focusing on MAGEC X.

Methods
Reports submitted to the Manufacturer and User Facility Device Experience database in relation to MAGEC devices were accessed and analysed using R Statistical Software. Exclusion criteria included duplicate and literature review reports (n = 54). Free-text data were analysed using inductive content analysis.

Results
1016 adverse events were reported to 11/30/2023. 99.0% (1006) were submitted by the manufacturer. Reports primarily arose from the UK (465, 45.8%) or US (421, 41.4%). From free-text data the most frequent adverse events were distraction mechanism failure (573), device wear (272), and actuator seal damage (180). Rod fracture (n = 48) was not significantly associated with rod diameter (≤ 5.0 mm or > 5.0 mm), p = 0.736. 234 reports referenced MAGEC X devices; actuator endcap separation was identified in 41.9% (99). Other events include failure of distraction (63), surface damage (31), and rod fracture (15). On 06/30/2020 MAGEC X2 received FDA approval. Twenty reports reference devices manufactured after this date, seven describe distraction mechanism failure; notably there are no reports of endcap separation.

Conclusion
These data represent the largest series of adverse events reported for MAGEC rods, including significant new data regarding MAGEC X. As well as endcap separation, failure of distraction, surface damage, and rod fracture were reported.

AbstractSalt bladders, specialized structures on the surface of quinoa leaves, secrete Na+ to mitigate the effects of the plant from abiotic stresses, particularly salt exposure. Understanding the development of these structures is crucial for elucidating quinoa’s salt tolerance mechanisms. In this study, we employed transmission electron microscopy to detail cellular differentiation across the developmental stages of quinoa salt bladders. To further explore the developmental trajectory and underlying molecular mechanisms, we conducted single-cell RNA sequencing on quinoa protoplasts derived from young leaves. This allowed us to construct a cellular atlas, identifying 13 distinct cell clusters. Through pseudotime analysis, we mapped the developmental pathways of salt bladders and identified regulatory factors involved in cell fate decisions. GO and KEGG enrichment analyses, as well as experimental results, revealed the impacts of salt stress and the deprivation of sulfur and nitrogen on the development of quinoa salt bladders. Analysis of the transcription factor interaction network in pre-stalk cells (pre-SC), stalk cells (SC), and epidermal bladder cells (EBCs) indicated that TCP5, YAB5, NAC078, SCL8, GT-3B, and T1P17.40 play crucial roles in EBC development. Based on our findings, we developed an informative model elucidating salt bladder formation. This study provides a vital resource for mapping quinoa leaf cells and contributes to our understanding of its salt tolerance mechanisms.
Flattening behaviour of weft-knitted spacer fabrics
Authors: Le Coz Ulysse , Ringenbach Pierre , Sakuma Atsushi , Yu Annie 
Published: November 2024

AbstractWeft-knitted spacer fabrics are thick 3D knitted structures prized for their cushioning properties which have gathered increasing attention in the last decade. The thickness of a spacer fabric is one of its most influential parameters and strongly impacts its cushioning properties, wearability, thermal insulation or permeability. However, the fabric's natural undulation and high deformability make its thickness measurement uneasy. The current standard measurement methods require to measure the fabric thickness after compressing it until a fixed threshold stress value is reached to flatten it. The diversity of these threshold values is confusing, and each of them is unsuitable to variety of fabric rigidity. In this article, a standard for thickness evaluation was proposed and used to measure the thickness of 20 samples knitted with 5 independent parameters. The measured thickness was compared to the thickness measured at a threshold value of 1 kPa and to a theoretical thickness. The proposed measurement standard was proved reproducible and efficient for all fabrics when the threshold measures showed large errors on the softer and stiffer samples. The flattening stress of the fabrics ranged from 86 to 5262 Pa and could not be approximated by a single standard value. The theoretical thickness was more accurate, predicting the thickness with an average error of 3.8%.
COMET: monitoring mitochondrial shock in anesthesiology and intensive care medicine
Authors: Yang Yan , Zhang Wei , Ma Zhengliang , Gu Xiaoping 
Published: November 2024

AbstractMitochondria, as the cellular end-users of oxygen and responsible for approximately 98% of total body oxygen consumption, play a significant role in the development of organ dysfunction during shock. Therefore, integrating information on mitochondrial oxygen homeostasis with macroscopic observations of macrocirculation and microcirculation is crucial for monitoring critically ill patients or those undergoing high-risk surgery. However, current clinical practice still lack reliable surrogate parameters for assessing mitochondrial function. The Cellular Oxygen METabolism (COMET) monitor, utilizing the protoporphyrin IX triplet state lifetime technique (PpIX-TSLT), represents the first clinical device capable of non-invasive, in vivo measurement of mitochondrial oxygen pressure and oxidative phosphorylation. Recent research suggests that implementing this real-time bedside monitoring will provide additional insights into microcirculatory dynamics and enhance patient management. This review will comprehensively detail the rationale, methodologies, evolution, and clinical applications of the technique, aiming at improving the understanding of mitochondrial pathology in daily clinical practice and facilitating the development of targeted therapeutic strategies.

Authors: Plattfaut Ralf , Rehse Jana-Rebecca , Jans Caspar , Schulte Matthias , van Wendel de Joode Joost 
Published: November 2024

AbstractRobotic Process Automation is an established technology in organizations. In the last years, it has also received considerable attention in scholarly research with publications, special issues, and academic conferences dedicated to the topic. Given that Robotic Process Automation has now moved beyond the initial hype, we can ask what research should focus on in the future. To address this question, we conducted a panel discussion to discuss its current state and future development. This panel, which took place at the Robotic Process Automation forum at the Business Process Management Conference 2023, included experts from academia and industry, covering strategy consultants, implementers, and tool providers. In this report, we present insights from the panel discussions. We especially focus on three future research directions on Robotic Process Automation that emerged from the panel.
African Studies Keyword: Organic
Authors: Rahier Nick , Devos Emelien 
Published: November 2024

AbstractThe concept of the organic serves as a keyword capturing emerging practices and epistemologies through which Africans navigate increasingly toxic lifeworlds. Noting a growing preoccupation with this term, the authors unpack its meaning based on their ethnographic fieldwork concerning two East African idioms: kienyeji and kiasili. What it means to be(come) organic is tied to older notions such as life flow, tradition, and the natural. Tracing how this concept engages with central themes in Africanist debates, the authors demonstrate that an Africanist theorizing about it foregrounds critical claims about the vitality of bodies and the viability of environments.
Cybersecurity Framework for Synthetic Data in Training Medical AI
Authors: Greser Jarosław 
Published: November 2024

AbstractThe development of medical artificial intelligence is dependent on the availability of vast quantities of data, a considerable proportion of which is medical data containing sensitive information pertaining to the health and well-being of patients. The use of such data is subject to extensive legal regulation and is further hindered by financial and organisational constraints, which can result in limitations on accessibility. One potential solution to this problem is the use of synthetic data. This article examines the potential for their use in light of cybersecurity requirements derived from horizontal and sectoral EU legislation. The outcome of this analysis is that EU legislation does not contain specific regulations on the use of synthetic data. Consequently, it cannot be concluded that there is any prohibition on their use. Moreover, while the Medical Device Regulation (MDR) contains some general requirements for cybersecurity, these are further specified by the provisions of the AI Act. It is important to note, however, that the AI Act will not apply to Class I medical devices, which are subject only to the MDR. Furthermore, only indirect obligations within the scope under consideration can be derived from the horizontal regulations, which will apply in a limited number of cases.
Maximal operators along flat curves with one variable vector field
Authors: Kim Joonil , Oh Jeongtae 
Published: November 2024

AbstractWe study a maximal average along a family of curves $\{(t,m(x_1)\gamma(t)):t\in [-r,r]\}$, where $\gamma|_{[0,\infty)}$ is a convex function and m is a measurable function. Under the assumption of the doubling property of $\gamma'$ and $1\leqslant m(x_1)\leqslant 2$, we prove the $L^p(\mathbb{R}^2)$ boundedness of the maximal average. As a corollary, we obtain the pointwise convergence of the average in r > 0 without any size assumption for a measurable m.
Denying the Obvious: Why Do Nominally Covert Actions Avoid Escalation?
Authors: Bloch Chase , McManus Roseanne W. 
Published: November 2024

AbstractIn 2014, Russia denied that its military was assisting separatists in eastern Ukraine, despite overwhelming evidence. Why do countries bother to deny hostile actions like this even when they are obvious? Scholars have argued that making hostile actions covert can reduce pressure on the target state to escalate. Yet it is not clear whether this claim applies when evidence of responsibility for the action is publicly available. We use three survey experiments to test whether denying responsibility for an action in the presence of contradictory evidence truly dampens demand for escalation among the public in the target state. We also test three causal mechanisms that might explain this: a rationalist reputation mechanism, a psychological mechanism, and an uncertainty mechanism. We do find a de-escalatory effect of noncredible denials. The effect is mediated through all three proposed causal mechanisms, but uncertainty and reputational concern have the most consistent effect.
The Moral Economy of the Ugandan Crowd in 1945
Authors: Hanson Holly 
Published: November 2024

AbstractIn 1945, actions which have been understood as strikes against wartime inflation occurred across colonized Africa: this essay identifies a deeper motivation in the events which happened in the Uganda Protectorate in early 1945. An understanding that people had a moral responsibility to act, and leaders had a moral responsibility to see them, to listen, and to respond led from a mobilization of workers on town streets, to efforts to see wrongful deaths acknowledged, to gatherings in the courtyard of the Buganda king in which he was almost overthrown. In each of the three stages of the protest, Ugandans of different ethnicities asserted an ethic of mutual obligation which acknowledged no boundary between the political and the economic, spoke to authority with an expectation that they would be heard, and drew on enduring knowledge of politics as well as a range of new ideas to solve the problems they confronted.
(Re)writing commentaries: Alexander on Metaphysics V 2 and Simplicius on Physics II 3
Authors: Kotwick Mirjam E. 
Published: November 2024

AbstractThis article presents and analyses new evidence for how Simplicius made use of Alexander of Aphrodisias for his commentary on Aristotle’s Physics. Alexander’s commentary on the Physics is lost to us (except for scholia on Physics IV–VIII), but, as argued in section II of this article, we have a slightly abridged version of Alexander’s commentary on Physics II 3 in the form of his commentary on Metaphysics V 2 (Aristotle’s Physics II 3 and Metaph. V 2 are more or less identical). This allows a comparison of Alexander’s and Simplicius’ commentaries on the same Aristotelian text. In section III, it is shown that Simplicius relies much more extensively on Alexander than his explicit references indicate. In section IV, it is shown that (a) when Simplicius refers to Alexander disapprovingly, he reports reliably what Alexander said, but that (b) when Simplicius refers to Alexander approvingly and as an authority in support of his own view, he provides a tendentious interpretation of Alexander’s argument. My results help to evaluate Simplicius’ reliability as a witness to the many works of ancient philosophy for which he is our only source.
