AbstractSodium‐ion batteries are a promising substitute for lithium batteries due to the abundant resources and low cost of sodium. Herein, honeycomb‐shaped MoSe2/reduced graphene oxide (rGO) composite materials are synthesized from graphene oxide (GO) and MoSe2 through a one‐step solvothermal process. Experiments show that the 3D honeycomb structure provides excellent electrolyte penetration while alleviating the volume change during electrochemical cycling. An anode prepared with MoSe2/rGO composites exhibits significantly improved sodium‐ion storage properties, where a large reversible capacity of 215 mAh g−1 is obtained after 2700 cycles at the current density of 30.0 A g−1 or after 5900 cycles at 8.0 A g−1. When such an anode is paired with Na3V2(PO4)3 to form a full cell, a reversible specific capacity of 107.5 mAh g−1 can be retained after 1000 cycles at the current of 1.0 A g−1. Transmission electron microscopy, X‐ray photoelectron spectroscopy and in situ X‐ray diffraction (XRD) characterization reveal the reversible storage reaction of Na ions in the MoSe2/rGO composites. The significantly enhanced sodium storage capacity is attributed to the unique honeycomb microstructure and the use of ether‐based electrolytes. This study illustrates that combining rGO with ether‐based electrolytes has tremendous potential in constructing high‐performance sodium‐ion batteries.
Phase‐Stabilized Crystal Etching to Unlock An Oxygen‐Vacancy‐Rich Potassium Vanadate For Ultra‐Fast Zn Storage

Published: September 2023

AbstractDespite holding the advantages of high theoretical capacity and low cost, the practical application of layered‐structured potassium vanadates in zinc ion batteries (ZIBs) has been staggered by the sluggish ion diffusion, low intrinsic electronic conductivity, and unstable crystal structure. Herein, for the first time, a phase stabilized crystal etching strategy is proposed to innovate an oxygen‐vacancy‐rich K0.486V2O5 nanorod composite (Ov‐KVO@rGO) as a high‐performance ZIB cathode. The in situ ascorbic acid assisted crystal etching process introduces abundant oxygen‐vacancies into the K0.486V2O5 lattices, not only elaborately expanding the lattice spacing for faster ion diffusion and more active sites due to the weakened interlayer electrostatic interaction, but also enhancing the electronic conductivity by accumulating electrons around the vacancies, which is also evidenced by density functional theory calculations. Meanwhile, the encapsulating rGO layer ably stabilizes the K0.486V2O5 crystal phase otherwise is hard to endure subject to such a harsh chemical etching. As a result, the optimized Ov‐KVO@rGO electrode delivers record‐high rate capabilities with 462 and 272.39 mAh g−1 at 0.2 and 10 A g−1, respectively, outperforming all previously reported potassium vanadate cathodes and most other vanadium‐based materials. This work highlights a significant advancement of layer‐structured vanadium based‐materials towards practical application in ZIBs.
Telegraph to Tether: Challenges in the Global Payments System and the Struggle between Private and Public Interests
Authors: Schenk Catherine R. 
Published: September 2023

Abstract
Cross-border payments systems are fundamental to the smooth operation of the global economy, but they have attracted relatively little public or academic interest. To support trade and commerce, the system needs to be fast, efficient, inclusive and transparent but these characteristics are challenged by long transaction chains, fragmentation and complexity, legacy technology and high compliance costs. The geopolitical importance was highlighted by the exclusion of Russia from Society for Worldwide Interbank Financial Telecommunications (SWIFT) in 2022. This chapter examines the changing technology and the origins of two key institutions (SWIFT and Clearing House Interbank Payments System in New York, or CHIPS) with special focus on the private ownership of this public good. It draws on new archive evidence from central banks, commercial banks and multilateral institutions to offer fresh insights into how the global payments system has evolved.
The ABJM Amplituhedron
Authors: He Song , Huang Yu-tin , Kuo Chia-Kai 
Published: September 2023

Abstract
In this paper, we take a major step towards the construction and applications of an all-loop, all-multiplicity amplituhedron for three-dimensional planar $$ \mathcal{N} $$
N
= 6 Chern-Simons matter theory, or the ABJM amplituhedron. We show that by simply changing the overall sign of the positive region of the original amplituhedron for four-dimensional planar $$ \mathcal{N} $$
N
= 4 super-Yang-Mills (sYM) and performing a symplectic reduction, only three-dimensional kinematics in the middle sector of even-multiplicity survive. The resulting form of the geometry, combined with its parity images, gives the full loop integrand. This simple modification geometrically enforces the vanishing of odd-multiplicity cuts, and manifests the correct soft cuts as well as two-particle unitarity cuts. Furthermore, the so-called “bipartite structures” of four-point all-loop negative geometries also directly generalize to all multiplicities. We introduce a novel approach for triangulating loop amplituhedra based on the kinematics of the tree region, resulting in local integrands tailored to “prescriptive unitarity”. This construction sheds fascinating new light on the interplay between loop and tree amplituhedra for both ABJM and $$ \mathcal{N} $$
N
= 4 sYM: the loop geometry demands that the tree region must be dissected into chambers, defined by the simultaneous positivity of maximal cuts. The loop geometry is then the “fibration” of the tree region. Using the new construction, we give explicit results of one-loop integrands up to ten points and two-loop integrands up to eight points by computing the canonical form of ABJM loop amplituhedron.
Pole-skipping as order parameter to probe a quantum critical point
Authors: Abbasi Navid , Landsteiner Karl 
Published: September 2023

Abstract
The holographic system described by Einstein-Maxwell-Chern-Simons dynamics in the bulk of AdS exhibits a chiral magnetic effect and a quantum critical point. Through numerical calculations, we find that the butterfly velocity can serve as a new identifier for the quantum critical point in this system. We show that the critical point is the point at which the butterfly velocity is equal to the speed of light in the direction of the magnetic field, while in the opposite direction the butterfly propagation vanishes. Furthermore, by studying the pole-skipping points of the response function of the operator dual to the tensor part of the metric perturbation in the bulk, we discover a set of order parameters that distinguish the two states of the system near the quantum critical point. Each of these order parameters is the sum of the absolute values of the real parts of momentum at all pole-skipping points associated with a particular frequency. This quantity vanishes in the disordered state while taking a positive value in the ordered state. In addition, our results confirm the idea that the chiral magnetic effect can manifest macroscopically through quantum chaos.
Anwendung des Vorsorgeprinzips nach Artikel 7 der Verordnung (EG) Nr. 178/2002: Allgemeine Grundsätze und Bewertung von Cannabidiol in Lebensmitteln

ZusammenfassungDas Vorsorgeprinzip ist in der Rechtsprechung und Gesetzgebung der Europäischen Union (EU) fest verankert. Im Lebensmittelrecht wurde das Vorsorgeprinzip in Art. 7 der Lebensmittel-Basisverordnung (EG) Nr. 178/2002 (BasisVO) etabliert. Dennoch findet das Vorsorgeprinzip sowohl in der Überwachungspraxis als auch in der nationalen Rechtsprechung nicht die angemessene Beachtung. Neben der historischen Entwicklung und der Anwendung in der nationalen und europäischen Rechtsprechung werden in diesem Beitrag die Möglichkeiten und Grenzen der Anwendung des Vorsorgeprinzips nach Art. 7 BasisVO am Beispiel von cannabidiolhaltigen (CBD) Produkten beleuchtet. Im Ergebnis wird festgestellt, dass die Behörden im Sinne des Vorsorgeprinzips aufgrund eines wahrscheinlichen Gesundheitsrisikos prioritäre Schutzmaßnahmen ergreifen können, die über die ohnehin erforderlichen Maßnahmen der Novel Food-Verordnung hinausgehen.
Serum concentration of dickkopf-related protein 1 (DKK1) in psoriatic arthritis in the context of bone remodelling
Authors: Biedroń Grzegorz , Czepiel Marcin , Siedlar Maciej , Korkosz Mariusz 
Published: September 2023

AbstractPsoriatic arthritis (PsA) is a chronic inflammatory disease, characterised by the pathological occurrence of two opposite phenomena—osteoresorption and osteogenesis. Dickkopf-related protein 1 (DKK1) which inhibits the Wingless protein (Wnt) signalling pathway has been shown to be a master regulator of bone remodeling in inflammatory rheumatic diseases. However, the exact relationship between DKK1 serum level and bone remodelling is not clear. The goal of this study is to review state-of-the-art knowledge on the association of serum DKK1 with a bone remodelling in PsA. The MEDLINE-PubMed, EMBASE, Scopus, Web of Science and DOAJ databases were searched for appropriate papers. The English terms: ‘DKK1’, ‘Dickkopf-1’ ‘Dickkopf related protein 1’, ‘psoriatic arthritis’ and ‘PsA’ were used for search purposes. Eight original articles and two reviews were identified up to August 2023. In four out of 8 discussed studies DKK1 serum level was higher in PsA patients than in healthy controls [Dalbeth, p < 0.01; Diani, p < 0.001; Chung, p < 0.01; Abd el Hamid, p < 0.001)], it was comparable in another (Daousiss, p = 0.430) and was lower in two (Fassio2017, p < 0.05; Fassio2019, p < 0.05). In one study, the comparative groups included patients with axial spondyloarthritis, where DKK1 serum levels were lower in PsA groups [Jadon, peripheral PsA, p = 0.01]. The true relative serum concentration of DKK1 in PsA, as well as its influence on osteogenesis and osteoresorption, is still equivocal. Further studies on this matter with consistent and stringent methodology are warranted.
Does controlled ovarian hyperstimulation in women with a history of borderline tumor influence recurrence rate?
Authors: Gao Han , Wei Wei , Li Yibing , Wei Heng , Wang Ning 
Published: September 2023

Abstract
Purpose
To determine the recurrence rate in the women with controlled ovarian hyperstimulation after a history of borderline ovarian tumors (BOT).

Methods
This was a retrospective analysis of 275 patients with BOT undergoing surgery for fertility preservation in our hospital between 2001 and 2017. Cases were divided into an assisted reproductive technology (ART) treatment group (n = 15) and a non-ART treatment group (n = 260). We compared the recurrence rate, survival rate and pregnancy outcomes between these two groups.

Results
The ART group had a higher recurrence rate (33.33% vs. 10.80%, P = 0.023). Survival analysis indicated that the recurrence time in patients undergoing ART was significantly shorter (P = 0.026). A low pregnancy rate before diagnosis, and high intraoperative blood loss, were associated with postoperative ART treatment (P < 0.05). Multivariate analysis showed that ART treatment and bilateral lesions both significantly increased the risk of recurrence (P < 0.05). The pathological type of recurrent tumors was often the same as the initial tumor.

Conclusion
The postoperative use of ART in patients with BOT significantly increased the recurrence rate, but does not significantly affect the overall survival rate of patients. Therefore, ART in such patients should be individualized, and close follow-up is necessary after ART.

Published: September 2023

AbstractTo determine the early factors associated with continuous positive airway pressure (CPAP) failure in moderate-to-late preterm infants (32 + 0/7 to 36 + 6/7 weeks’ gestation) from the NEOBS cohort study. The NEOBS study was a multi-center, prospective, observational study in 46 neonatal intensive care units in France, which included preterm and late preterm infants with early neonatal respiratory distress. This analysis included a subset of the NEOBS population who had respiratory distress and required ventilatory support with CPAP within the first 24 h of life. CPAP failure was defined as the need for tracheal intubation within 72 h of CPAP initiation. Maternal and neonatal clinical parameters in the delivery room and clinical data at 3 h of life were analyzed. CPAP failure occurred in 45/375 infants (12%), and compared with infants with CPAP success, they were mostly singletons (82.2% vs. 62.1%; p < 0.01), had a lower Apgar score at 10 min of life (9.1 ± 1.3 vs. 9.6 ± 0.8; p = 0.02), and required a higher fraction of inspired oxygen (FiO2; 34.4 ± 15.9% vs. 22.8 ± 4.1%; p < 0.0001) and a higher FiO2*positive end-expiratory pressure (PEEP) (1.8 ± 0.9 vs. 1.1 ± 0.3; p < 0.0001) at 3 h. FiO2 value of 0.23 (R2 = 0.73) and FiO2*PEEP of 1.50 (R2 = 0.75) best predicted CPAP failure. The risk of respiratory distress and early CPAP failure decreased 0.7 times per 1-week increase in gestational age and increased 1.7 times with every one-point decrease in Apgar score at 10 min and 19 times with FiO2*PEEP > 1.50 (vs. ≤ 1.50) at 3 h (R2 of the overall model = 0.83). Conclusion: In moderate-to-late preterm infants, the combination of singleton pregnancy, lower Apgar score at 10 min, and FiO2*PEEP > 1.50 at 3 h can predict early CPAP failure with increased accuracy.

What is Known:

•Respiratory distress syndrome (RSD) represents an unmet medical need in moderate-to-late preterm births and is commonly treated with continuous positive airway pressure (CPAP) to reduce mortality and the need for additional ventilatory support.

• Optimal management of RSD is yet to be established, with several studies suggesting that identification of predictive factors for CPAP failure can aid in the prompt treatment of infants likely to experience this failure.

What is New:

•Secondary analysis of the observational NEOBS study indicated that oxygen requirements during CPAP therapy, especially the product of fraction of inspired oxygen (FiO2) and positive end-expiratory pressure (PEEP), are important factors associated with early CPAP failure in moderate-to-late term preterm infants.

•The combination of a singleton pregnancy, low Apgar score at 10 minutes, and high FiO2*PEEP at 3 hours can predict early CPAP failure with increased accuracy, highlighting important areas for future research into the prevention of CPAP failure.

Published: September 2023

AbstractThe risk of dysphagia and/or aspiration is determined using screening tests, such as the repeated saliva swallowing test and modified water swallowing test, which evaluate cued swallowing. However, humans masticate and swallow foods with various consistencies, forms, and amounts, without conscious awareness. Therefore, this study aimed to examine the difference in the behavior of masticatory and swallowing muscles during spontaneous versus cued swallowing through a series of mastication and swallowing processes by evaluating surface electromyogram (sEMG) signals. The effect of the consistency and amount of food on the behavior of these muscles was also investigated. The sEMG recordings of the masseter muscles and anterior belly of the digastric muscle for 12 subjects, and genioglossus muscle for 5 subjects were obtained. The genioglossus activity was recorded using custom-made ball electrodes. The test foods were cookies and tofu, in amounts of 2 g and 4 g. The normalized muscle activity (integrated EMG), duration of the muscle activity, initial activation timepoint of each muscle, and total duration of swallowing were compared among four conditions. The activity of each muscle was significantly higher during the swallowing of cookies than tofu, for 4 g vs 2 g, and for cued versus spontaneous swallowing. The duration of each muscle activity, initial activation timepoint, and total duration of swallowing were significantly longer for cookies versus tofu, for 4 g vs 2 g, and for spontaneous versus cued swallowing. These results suggest that the behavior of the masticatory and swallowing muscles is affected by cued swallowing and by the consistency and amount of food.

Published: September 2023

Abstract
Background
Fibroblast growth factor 23 (FGF23) is a bone-derived hormone that plays a central role in chronic kidney disease-mineral bone disorder and is associated with CKD progression and cardiovascular morbidity. Factors related to CKD-associated anemia, including iron deficiency, can increase FGF23 production. This study aimed to assess whether anemia and/or iron deficiency are associated with increased circulating concentrations of FGF23 in the large, well-characterized Chronic Kidney Disease in Children (CKiD) study cohort.

Methods
Hemoglobin concentrations, iron parameters, C-terminal (total) FGF23, intact FGF23, and relevant covariables were measured in cross-sectional analysis of CKiD study subjects.

Results
In 493 pediatric patients with CKD (median [interquartile range] age 13 [9, 16] years), the median estimated glomerular filtration rate was 48 [35, 61] ml/min/1.73 m2, and 103 patients (21%) were anemic. Anemic subjects had higher total FGF23 concentrations than non-anemic subjects (204 [124, 390] vs. 109 [77, 168] RU/ml, p < 0.001). In multivariable linear regression modeling, anemia was independently associated with higher total FGF23, after adjustment for demographic, kidney-related, mineral metabolism, and inflammatory covariables (standardized β (95% confidence interval) 0.10 (0.04, 0.17), p = 0.002). In the subset of subjects with available iron parameters (n = 191), iron deficiency was not associated with significantly higher total FGF23 concentrations. In the subgroup that had measurements of both total and intact FGF23 (n = 185), in fully adjusted models, anemia was significantly associated with higher total FGF23 (standardized β (95% CI) 0.16 (0.04, 0.27), p = 0.008) but not intact FGF23 (standardized β (95% CI) 0.02 (−0.12, 0.15), p = 0.81).

Conclusions
In this cohort of pediatric patients with CKD, anemia was associated with increased total FGF23 levels but was not independently associated with elevated intact FGF23, suggesting possible effects on both FGF23 production and cleavage. Further studies are warranted to investigate non-mineral factors affecting FGF23 production and metabolism in CKD.

Assessing the alerting capabilities of the Earthquake Network early warning system in Haiti with Monte Carlo simulations
Authors: Finazzi Francesco , Massoda Tchoussi Frank Yannick 
Published: September 2023

AbstractSmartphone-based earthquake early warning systems implemented by citizen science initiatives are characterised by significant variability in their smartphone network geometry. This has a direct impact on the earthquake detection capability and system performance. Here, a Monte Carlo-based simulation framework is implemented to infer relevant earthquake detection quantities such as detection distance from the epicentre, detection delay, and warning time for people exposed to high ground shaking levels. The framework is applied to Haiti, which has experienced deadly earthquakes in recent decades, and to the Earthquake Network citizen science initiative, which is popular in the country. It is found that warning times of up to 12 s for people exposed to intensities between 7.5 and 8.5 on the modified Mercalli scale are possible starting from a relatively low involvement of citizens in the initiative (i.e., from 1 Haitian in 10,000).
Better-than-$$\frac{4}{3}$$-approximations for leaf-to-leaf tree and connectivity augmentation

Published: September 2023

AbstractThe Connectivity Augmentation Problem (CAP) together with a well-known special case thereof known as the Tree Augmentation Problem (TAP) are among the most basic Network Design problems. There has been a surge of interest recently to find approximation algorithms with guarantees below 2 for both TAP and CAP, culminating in the currently best approximation factor for both problems of 1.393 through quite sophisticated techniques. We present a new and arguably simple matching-based method for the well-known special case of leaf-to-leaf instances. Combining our work with prior techniques, we readily obtain a $$(4/3+\varepsilon )$$

Modeling Long-Term Facilitation of Respiration During Interval Exercise in Humans
Authors: Yamashiro Stanley M. , Kato Takahide , Matsumoto Takaaki 
Published: September 2023

AbstractLong-term facilitation (LTF) of respiration has been mainly initiated by intermittent hypoxia and resultant chemoreceptor stimulation in humans. Comparable levels of chemoreceptor stimulation can occur in combined exercise and carbon dioxide (CO2) inhalation and lead to LTF. This possibility was supported by data collected during combined interval exercise and 3% inhaled CO2 in seven normal subjects. These data were further analyzed based on the dynamics involved using mathematical models in this study. Previously estimated peripheral chemoreceptor sensitivity during light exercise (40 W) with air or 3% inhaled CO2 approximately doubled resting sensitivity. Ventilation after a delay increased by 17.0 ± 2.48 L/min (p < 0.001) during recovery following 45% maximal oxygen uptake ($$V_{{{\text{O}}_{2} \max }}$$
