Envy-Free Division of Multilayered Cakes
Authors: Igarashi Ayumi , Meunier Frédéric 
Published: September 2024

Dividing a multilayered cake under nonoverlapping constraints captures several scenarios (e.g., allocating multiple facilities over time where each agent can utilize at most one facility simultaneously). We establish the existence of an envy-free multidivision that is nonoverlapping and contiguous within each layer when the number of agents is a prime power, solving partially an open question by Hosseini et al. [Hosseini H, Igarashi A, Searns A (2020) Fair division of time: Multi-layered cake cutting. Proc. 29th Internat. Joint Conf. Artificial Intelligence (IJCAI), 182–188; Hosseini H, Igarashi A, Searns A (2020) Fair division of time: Multi-layered cake cutting. Preprint, submitted April 28, http://arxiv.org/abs/2004.13397 ]. Our approach follows an idea proposed by Jojić et al. [Jojić D, Panina G, Živaljević R (2021) Splitting necklaces, with constraints. SIAM J. Discrete Math. 35(2):1268–1286] for envy-free divisions, relying on a general fixed-point theorem. We further design a fully polynomial-time approximation scheme for the two-layer, three-agent case, with monotone preferences. All results are actually established for divisions among groups of almost the same size. In the one-layer, three-group case, our algorithm is able to deal with any predetermined sizes, still with monotone preferences. For three groups, this provides an algorithmic version of a recent theorem by Segal-Halevi and Suksompong [Segal-Halevi E, Suksompong W (2021) How to cut a cake fairly: A generalization to groups.

Published: September 2024

AbstractEndothelin‐1 (ET‐1) and its receptors are linked to increases in sensitivity of the chemoreceptors to hypoxic stress and the development of hypertension in preclinical models. We hypothesized ET receptor antagonism would lower resting blood pressure (BP) as well as the acute BP response to chemoreflex stress. Twenty‐four men (31 ± 5 years, 26 ± 3 kg/m2) completed two study visits (control, bosentan). On each visit, BP was assessed under three conditions: (1) normoxia (FiO2 0.21), (2) chemoreflex excitation via hypoxia (FiO2 0.05–0.21), (3) chemoreflex inhibition via hyperoxia (FiO2 1.00). Bosentan increased plasma ET‐1 (0.94 ± 0.90 to 1.27 ± 0.62 pg/mL, p = 0.004), supporting receptor blockade. Resting diastolic (73 ± 5 to 69 ± 7 mmHg, p = 0.007) and mean (93 ± 7 to 88 ± 7 mmHg, p = 0.005) BP were reduced following bosentan compared to control with no change in systolic BP (p = 0.507). The mean BP response to both acute hypoxia (−0.48 ± 0.38 to −0.25 ± 0.31 mmHg/%, p = 0.004) and hyperoxia (area under the curve −93 ± 108 to −27 ± 66 AU, p = 0.018) were attenuated following bosentan. Acute ET receptor inhibition attenuates the rise in BP during chemoreflex excitation as well as the fall in BP during chemoreflex inhibition in healthy young men. These data support a role for ET‐1 in control of resting BP, possibly through a chemoreceptor‐mediated mechanism.

Published: September 2024

AbstractPrevious studies report contradicting age‐related neurovascular coupling (NVC). Few studies assess postural effects, but less investigate relationships between age and NVC within different postures. Therefore, this study investigated the effect of age on NVC in different postures with varying cognitive stimuli. Beat‐to‐beat blood pressure, heart rate and end‐tidal carbon dioxide were assessed alongside middle and posterior cerebral artery velocities (MCAv and PCAv, respectively) using transcranial Doppler ultrasonography in 78 participants (31 young‐, 23 middle‐ and 24 older‐aged) with visuospatial (VST) and attention tasks (AT) in various postures at two timepoints (T2 and T3). Between‐group significance testing utilized one‐way analysis‐of‐variance (ANOVA) (Tukey post‐hoc). Mixed three‐way/one‐way ANOVAs explored task, posture, and age interactions. Significant effects of posture on NVC were driven by a 3.8% increase from seated to supine. For AT, mean supine %MCAv increase was greatest in younger (5.44%) versus middle (0.12%) and older‐age (0.09%) at T3 (p = 0.005). For VST, mean supine %PCAv increase was greatest at T2 and T3 in middle (10.99%/10.12%) and older‐age (17.36%/17.26%) versus younger (9.44%/8.89%) (p = 0.004/p = 0.002). We identified significant age‐related NVC effects with VST‐induced hyperactivation. This may reflect age‐related compensatory processes in supine. Further work is required, using complex stimuli while standing/walking, examining NVC, aging and falls.
Forecasting gasification sustainability through enhanced K-nearest neighbour models for hydrogen and nitrogen amount
Authors: Du Feng 
Published: September 2024

Abstract
This study pioneers a method for forecasting hydrogen and nitrogen quantities in gasification processes, which is crucial for transforming carbon-based materials into valuable gases with minimal environmental impact. It addresses the pressing need for precise and economical solutions in gasification by streamlining estimation procedures across various operational conditions. Anchored in historical data, the K-nearest neighbour’s (KNN) model forms the core of this method, adeptly capturing intricate relationships between input variables and gas production results. What sets this research apart is the integration of advanced optimization techniques, Beluga whale optimization (BWO), and Northern Goshawk Optimization (NGO), further refining the accuracy of the KNN model’s predictions. This work signifies a substantial stride in optimizing gasification processes, offering a pathway towards more efficient and sustainable conversion of carbon-based materials, showcasing the potential of data-driven sustainability in this domain, and ultimately diminishing the environmental impact of these operations. Results highlight the outstanding predictive performance of the KNNG model, achieving an impressive R
2 value of 0.995 and 0.994 during training. Notably, both the KNNG and KNBW models outperformed the basic KNN model in forecasting gasification outputs, underscoring the reliability and effectiveness of these optimized models in predicting these processes.
Flows of geometric structures
Authors: Fadel Daniel , Loubeau Eric , Moreno Andrés J. , Sá Earp Henrique N.

Abstract
We develop an abstract theory of flows of geometric 𝐻-structures, i.e., flows of tensor fields defining 𝐻-reductions of the frame bundle, for a closed and connected subgroup

H

H\subset\mathrm{SO}(n)

, on any connected and oriented 𝑛-manifold with sufficient topology to admit such structures.
The first part of the article sets up a unifying theoretical framework for deformations of 𝐻-structures, by way of the natural infinitesimal action of

GL

\mathrm{GL}(n,\mathbb{R})

on tensors combined with various bundle decompositions induced by 𝐻-structures.
We compute evolution equations for the intrinsic torsion under general flows of 𝐻-structures and, as applications, we obtain general Bianchi-type identities for 𝐻-structures, and, for closed manifolds, a general first variation formula for the

L

L^{2}

-Dirichlet energy functional ℰ on the space of 𝐻-structures.
We then specialise the theory to the negative gradient flow of ℰ over isometric 𝐻-structures, i.e., their harmonic flow.
The core result is an almost-monotonocity formula along the flow for a scale-invariant localised energy, similar to the classical formulas by Chen–Struwe [M. Struwe, On the evolution of harmonic maps in higher dimensions, J. Differential Geom.
28 (1988), 3, 485–502; Y. M. Chen and M. Struwe, Existence and partial regularity results for the heat flow for harmonic maps, Math. Z.
201 (1989), 1, 83–103] for the harmonic map heat flow.
This yields an 𝜀-regularity theorem and an energy gap result for harmonic structures, as well as long-time existence for the flow under small initial energy, relative to the

-norm of initial torsion, in the spirit of Chen–Ding [Y. M. Chen and W. Y. Ding, Blow-up and global existence for heat flows of harmonic maps, Invent. Math.
99 (1990), 3, 567–578].
Moreover, below a certain energy level, the absence of a torsion-free isometric 𝐻-structure in the initial homotopy class imposes the formation of finite-time singularities.
These seemingly contrasting statements are illustrated by examples on flat 𝑛-tori, so long as the set

Published: September 2024

Abstract
In the present paper we investigate three-dimensional dynamical mixed boundary-transmission problems for
composed body consisting of two adjacent anisotropic elastic components having a common interface surface.
The two contacting elastic components are subject to different mathematical models: Green–Lindsay’s model of
generalized thermo-electro-magneto-elasticity in one
component and Green–Lindsay’s model of generalized thermo-elasticity in the other one.
We assume that the composed elastic structure under consideration contains an
interfacial crack.
We prove the uniqueness and existence theorems in appropriate function spaces.

Abstract
China is the largest producer of jujubes in the world, with the Xinjiang region accounting for about 50 % of the total production. However, local jujube processing still relies on traditional methods, leading to reduced industrial efficiency. Research shows that jujube polysaccharides possess various biological properties, such as antioxidant, anti-tumor, and anti-inflammatory activities. Enhancing the extraction of jujube polysaccharides to boost their food, medicinal, and economic value has become an important development direction of the jujube industry. This paper reviews the current research on the active functions of grey jujube polysaccharides, extraction technologies, and recent advancements in their production and application. It systematically introduces both traditional and emerging extraction technologies and summarizes the current state of production and application of grey jujube polysaccharides. The aim is to provide references for other researchers interested in jujube polysaccharides and to extend the value chain of the grey jujube industry.
L’exception saxonne: le curieux cas d’Ariohan dans le Cycle de
Guiron le Courtois
Authors: Conti Inès 
Published: September 2024

Résumé
Réputé pour sa tonalité tant belliqueuse qu’épique, le Roman de Meliadus, premier volet du Cycle de Guiron le Courtois, se solde sur une invasion saxonne et le conflit armé qui en découle. Héros éponyme du texte, le roi Méliadus de Léonois, père de Tristan, fait partie des forces arthuriennes au combat et luttera dans un duel final contre Ariohan, prince des Saxons à leur tête. Ariohan se révèle un personnage non seulement individualisé, émergeant de la masse saxonne que connaissent habituellement les romans arthuriens en prose, mais également courtois, valeureux, digne d’un statut arthurien que d’autres personnages extérieurs au royaume de Logres ne connaissent que rarement. Cet article étudie l’élaboration de ce personnage au fil du Meliadus ainsi que son intertextualité arthurienne.
The Linguistic Provenance of the Hebrew King Arthur (1279) Reassessed
Authors: Jacobowitz-Efron Leon 
Published: September 2024

Abstract
Based on its inclusion of non-Hebrew Italian loanwords and the sole surviving manuscript copy being Italian, the current consensus among scholars is that an Italian Jew authored Melekh Artus (1279), the only extant medieval Hebrew translation of Arthurian material. The following study destabilizes this consensus opinion demonstrating why these loanwords are a precarious tool when ascertaining this text’s linguistic provenance. Not only are most of the said loanwords not necessarily Italian, but, using Italian copies of the French biblical commentator Rashi, this study establishes that Jewish Italian scribes sometimes Italianized Old French loanwords they encountered in their Hebrew sources. Thus, the few loanwords that are Italianisms do not prove Italian authorship but merely that the sole surviving copy was produced by an Italian-Jewish scribe adhering to the scribal conventions of his times.
L’
annominatio
en question dans quelques textes arthuriens en vers (xiie
-xiiie
siècles): généralités et applications à l’étude des rimes
Authors: James-Raoul Danièle 
Published: September 2024

Résumé
L’annominatio est une figure de rhétorique qui met en jeu la forme sonore, voire graphique, d’un mot en lien avec un ou d’autres mots selon de multiples modalités: elle est fondamentalement une figure de diction mais, dans la mesure où la répétition en est un élément constitutif essentiel, elle tient aussi d’une figure de construction. À l’époque médiévale, l’annominatio conditionne l’esthétique littéraire en général, l’écriture des vers en particulier, leur récitation ou leur lecture; elle n’est évidemment pas spécifique de la littérature arthurienne, mais la coloration et le dynamisme qu’elle apporte à ces textes permet d’entrer dans le style de leurs auteurs, de particulariser leur plume, voire, sur certains points, de l’identifier. Elle fait entendre le caractère très sonore de la langue française de cette époque. Comme toute figure de style, elle a un rôle argumentatif (elle insiste, souligne, établit des liens implicites et symboliques entre ce qui, a priori, semble ne pas en avoir, elle aide à la mémorisation) et un rôle ornemental (elle est plaisante, elle induit la variation ou la surprise, conduit le rythme, elle creuse des sillons sonores, graphiques et sémantiques dans la platitude du texte). Dans la succession de mètres courts comme les octosyllabes à rimes suivies, elle possède une importance particulière, parce qu’elle investit par prédilection la rime, en exemplifie les possibles réalisations et c’est sur ce sujet que je concentrerai mon attention dans la seconde partie de cette étude. S’intéresser à l’annominatio aux xii
e et xiii
e siècles dans quelques textes jalonnant la littérature arthurienne, c’est attirer l’attention sur l’histoire littéraire, l’esthétique et les considérations grammairiennes sur le langage telles qu’on peut les trouver dans les arts poétiques, autant que sur l’art de la versification dans nos romans, trop souvent laissé pour compte.
A Schema for Artorius: History, John Heath-Stubbs, and the Last Modernist Epic
Authors: Wise Dennis Wilson 
Published: September 2024

Abstract
Although John Heath-Stubbs’s long modernist epic Artorius is largely unknown, this ambitious text combines a cyclical vision of history with a linear one on its way to understanding Great Britain’s loss of imperial status. If this point has generally been missed, the complexity of Heath-Stubbs’s multiple symbolic superstructures partly accounts for the text’s unfortunate reception. Accordingly, I present an explanatory schema for Artorius in line with what other modernist texts – most famously Joyce’s Ulysses – have benefitted from. Besides unpacking the symbolic superstructures used by Heath-Stubbs, I also address how the poet, who lived in Egypt during the 1956 Suez crisis, uses them to answer a British nation that can no longer identify as a global power.
Selpercatinib prior to radioactive iodine for pediatric papillary thyroid carcinoma

Published: September 2024

Abstract

Objectives
We introduced selpercatinib prior to radioactive iodine therapy prior to radioactive iodine therapy (RAI) for pediatric papillary thyroid cancer (PTC) to enhance the tumorical effects of RAI.

Case presentation
PTC has an excellent prognosis but is commonly associated with local and distant metastases. Successful complete response to the current standard of care, thyroidectomy with lymph node resection and RAI, is achieved in only a small minority of cases with metastases. The direct effect of tyrosine kinase inhibitors (TKIs) on tumor regression has been confirmed in several randomized controlled studies, while the increased RAI uptake has been reported in small case series, but typically TKIs are currently reserved third-line. Selpercatinib is a TKI that specifically has a durable effect in RET-fusion positive malignancies. We describe a 10-year-old Hispanic girl with metastatic PTC treated with total thyroidectomy and extensive lymph node resection. Evaluation for relevant genetic drivers of the malignancy revealed a strong overexpression of the RET tyrosine kinase domain indicative of a RET gene fusion. Selpercatinib 120 mg twice daily given orally was initiated prior to the initial dose of RAI to achieve further tumor regression by a direct cytostatic effect and then secondarily enhancement of RAI uptake. Minimal side effects occurred, specifically intermittent mild skin rashes that resolved. Resolution of distal lung metastases was noted on CT imaging. RAI was then administered 9 months afterward, with ultimately achievement of a low thyroglobulin level 1.0 ng/mL 11 months after RAI.

Conclusions
In conclusion, selpercatinib given prior to the initial dose of adjunctive RAI for RET-fusion positive PTC is a well-tolerated intervention that further reduces tumor burden and potentially enhances the tumorcidal effects of RAI.
Influence of post heat treatment on tribological and microstructural properties of plasma wire arc additive manufactured maraging steels
Authors: Kaya Esad , Ulutan Mustafa , Çakır Ersin , Buytoz Soner 
Published: September 2024

Abstract
Metallic alloys are increasingly being produced using wired arc additive manufacturing (WAAM). In this study, 18Ni300 defect-free maraging steels were produced using the WAAM technique. A traditional solution treatment, direct aging, and cryogenic heat treatment processes were applied to the WAAM produced maraging steels. The influence of conventional and novel cryogenic heat treatments on microstructural, mechanical, and tribological properties were examined. The microstructure of the as-built materials obtained by WAAM thermal cycling has mainly been homogenized through the solution, direct-aging, and cryogenic heat treatments. As a result, homogeneously distributed precipitate phases were obtained and the hardness increased by 30 % with a combination different post heat treatments. The cryogenic heat treatment improved the martensitic transformation and facilitated the formation of various Fe–Ni–Mo–Ti-containing intermetallic precipitates. Similarly, because of the different heat treatments, the wear resistance improved by a factor of 2–5.5 relative to the as-built material. Adding the cryogenic heat treatment to the traditional heat treatment procedure improves wear resistance by a factor of 1.2–2.9.
