AbstractLi‐ion transport and phase transition of solid electrolytes are critical and fundamental issues governing the rate and cycling performances of solid‐state batteries. In this work, in‐operando high‐pressure nuclear magnetic resonance (NMR) spectroscopy for the solid‐state battery is developed and applied, in combination with 6Li‐tracer NMR and high‐resolution NMR spectroscopy, to investigate the Li10GeP2S12 electrolyte under true‐to‐life operation conditions. The results reveal that the Li10GeP2S12 phase may become more disordered and a large amount of conductive metastable β‐Li3PS4 as the glassy matrix in the electrolyte transforms into less conductive phases, mainly γ‐Li3PS4, when high current densities (e.g., ≥0.5 mA cm−2) are applied to the electrolyte. The overall Li‐transport also varies and shows a tendency of boundary phases and Li10GeP2S12 synergistic dominant conduction at high currents. Accordingly, a mechanism of structural change induced by stress variation due to the drastic morphological change during Li‐In alloying at high currents, and the local Li+ diffusion coefficient discrepancy is proposed. These new findings of Li‐ion transport and boundary phase transition in Li10GeP2S12 solid electrolyte under high‐pressure and high current density are first reported and will help provide previously lacking insights into the relationship of structure and performance of Li10GeP2S12.

AbstractIntegrating a graphene transparent electrode (TE) matrix with driving circuits is essential for the practical use of graphene in optoelectronics such as active‐matrix organic light‐emitting diode (OLED) display, however it is disabled by the transport of carriers between graphene pixels after deposition of a semiconductor functional layer caused by the atomic thickness of graphene. Here, the carrier transport regulation of a graphene TE matrix by using an insulating polyethyleneimine (PEIE) layer is reported. The PEIE forms an ultrathin uniform film (≤10 nm) to fill the gap of the graphene matrix, blocking horizontal electron transport between graphene pixels. Meanwhile, it can reduce the work function of graphene, improving the vertical electron injection through electron tunneling. This enables the fabrication of inverted OLED pixels with record high current and power efficiencies of 90.7 cd A−1 and 89.1 lm W−1, respectively. By integrating these inverted OLED pixels with a carbon nanotube‐based thin‐film transistor (CNT‐TFT)‐driven circuit, an inch‐size flexible active‐matrix OLED display is demonstrated, in which all OLED pixels are independently controlled by CNT‐TFTs. This research paves a way for the application of graphene‐like atomically thin TE pixels in flexible optoelectronics such as displays, smart wearables, and free‐form surface lighting.

Published: June 2023

AbstractThis study establishes and validates a series of three dimentional (3D) DNA origami frameworks (DOFs) carrying imaging probes to evaluate their pharmacokinetics and real‐time bio‐distribution in mice. Three typical DOFs with distinguished structural properties are subjected to mice intravenous injection to systematically investigate their in vivo behaviors. Tracing the radioisotope zirconium‐89 (89Zr) trapped at the inner space of the frameworks, positron emission tomography (PET) imaging is employed to record the real‐time bio‐distribution of the structures and acquire their pharmacokinetic parameters in the major metabolic organs. The 3D DOFs show different behavior compared to previous structures, with lower kidney accumulation and higher liver retention. Modifications to the structures, such as exposed ssDNA or polyethylene glycol (PEG) moieties, impact their behavior, but are structure‐dependent. The 43 nm icosahedra framework among the DOFs perform the best in liver targeting, with the ssDNA extensions enhancing this tendency. The modification of triantennary N‐acetylgalactosamine (GalNAc), further improves its uptake in liver cells, especially in hepatocytes over other cell types, discovered by flow cytometry analysis.

Published: June 2023

AbstractVanadyl phosphate (VOPO4·2H2O) has been regarded as one of the most promising cathode materials for aqueous Zn‐ion batteries due to its distinct layered structure. However, VOPO4·2H2O has not yet demonstrated the exceptional Zn ion storage performance owing to the structural deterioration during repeated charging/discharging process and poor intrinsic conductivity. In this work, 2D sodium vanadyl phosphate (NaVOPO4·0.83H2O, denoted as NaVOP) is designed as a cathode material for Zn‐ion batteries, in which sodium ions are preinserted into the interlayer, replacing part of water. Benefiting from the in situ surface oxidization, improved electronic conductivity, and increased hydrophobicity, the NaVOP electrode exhibits a high discharge capacity of 187 mAh g−1 at 0.1 A g−1 after activation, excellent rate capability and enhanced cycling performance with 85% capacity retention after 1500 cycles at 1 A g−1. The energy storage mechanism of the NaVOP nanoflakes based on the rapid Zn2+ and H+ intercalation pseudocapacitance are investigated via multiple ex situ characterizations.
Effects of individual strategies for resource access on collaboratively maintained irrigation infrastructure
Authors: Stern Jordan L. , Siddiqi Afreen , Grogan Paul T. 
Published: June 2023

AbstractBuilt infrastructure for water and energy supply, transportation, and other such services underpins human well‐being and socioeconomic development. A fundamental understanding of how infrastructure design and user strategies interact can guide important design decisions as well as policy formulation for ensuring long‐term infrastructure viability in conjunction with improved individual user benefits. In this work, an agent based model (ABM) is developed to study this issue for the specific case of irrigation canals. Cooperatively maintained irrigation canals serve essential roles in sustaining agriculture‐based economies in many regions. Canal system design can strongly affect benefits derived by distributed users, regional agricultural output, and the long‐term viability of the shared infrastructure itself. Here, an ABM is used to investigate how an option to use an independent water source interacts with canal design to affect canal maintenance cooperation and farmer income. The independent water source is stylized as a well that provides access to groundwater and represents a strategically robust design option; a design option that reduces the implementer's utility vulnerability to unfavorable actions by other actors. Research in other systems has demonstrated that strategically robust designs can improve both implementer utility and the probability of collaboration. The results of this research, in contrast, demonstrate that the option of individual resource access, the strategically robust design option, as represented by a well, reduces cooperative maintenance in most cases. However, wells also improve farmer income, especially for downstream farmers that are most affected by water theft.
Synergistic use of ultra‐high‐performance fiber‐reinforced concrete (UHPFRC) and carbon fiber‐reinforced polymer (CFRP) for improving the impact resistance of concrete‐filled steel tubes
Authors: Saini Dikshant , Shafei Behrouz 
Published: June 2023

SummaryConcrete‐filled steel tubes (CFSTs) have received growing attention, owing to their rapid construction, reduced labor requirement, and reasonable material cost. While in service, the CFSTs can be subjected to unexpected impact loads, originating from vehicle and vessel collision, as well as water‐ and wind‐borne debris impact. Such extreme loading events often cause a partial or complete failure of conventional CFSTs, risking the safety and performance of the entire structural systems that rely on them. To address this issue, the current study explores how two advanced composite materials, including ultra‐high‐performance fiber‐reinforced concrete (UHPFRC) and carbon fiber‐reinforced polymer (CFRP), can be utilized to provide superior mechanical properties and minimize the vulnerability of CFSTs to impact loads. The composite materials under consideration are appropriate for both new and existing structures, in which normal‐strength concrete can be replaced with UHPFRC, while CFRP sheets can further strengthen the CFSTs. For obtaining in‐depth insights, a computational framework validated with the experimental tests was developed in the current study. Using a set of representative impact scenarios, various response measures, such as internal forces and deflections, as well as the energy absorbed by the CFSTs, were recorded during impact simulations. The investigations were then further extended to capture the influence of the main design parameters related to concrete, CFRP, and steel tube. From the conducted investigations, an energy absorption index was introduced, as a measure to evaluate the performance of CFSTs under impact loads.
Chromoelectric field correlator for quarkonium transport in the strongly coupled $$ \mathcal{N} $$ = 4 Yang-Mills plasma from AdS/CFT
Authors: Nijs Govert , Scheihing-Hitschfeld Bruno , Yao Xiaojun 
Published: June 2023

Abstract
Previous studies have shown that a gauge-invariant correlation function of two chromoelectric fields connected by a straight timelike adjoint Wilson line encodes crucial information about quark-gluon plasma (QGP) that determines the dynamics of small-sized quarkonium in the medium. Motivated by the successes of holographic calculations to describe strongly coupled QGP, we calculate the analog gauge-invariant correlation function in strongly coupled $$ \mathcal{N} $$
N
= 4 supersymmetric Yang-Mills theory at finite temperature by using the AdS/CFT correspondence. Our results indicate that the transition processes between bound and unbound quarkonium states are suppressed in strongly coupled plasmas, and moreover, the leading contributions to these transition processes vanish in both the quantum Brownian motion and quantum optical limits of open quantum system approaches to quarkonia.
Phases of theories with fermions in AdS
Authors: Kakkar Astha , Sarkar Swarnendu 
Published: June 2023

Abstract
We study the phases of Yukawa theories at weak coupling and the Gross-Neveu models in AdS spaces at zero and finite temperature. Following the method used in [15], we first compute the one-loop partition functions, using the generalized eigenfunctions of the Dirac and Laplace operators on Euclidean AdS in the Poincaré coordinates. These functions satisfy desired periodicities under thermal identification. The method replicates results for partition functions known in the literature. We then study the phases of these field theories with fermions as regions in the corresponding parameter spaces at zero temperature. The phases and the corresponding phase boundaries are further identified as a function of the mass-squared of the scalar field and temperature for the Yukawa theories. While for the Gross-Neveu models, the changes in the phases as a function of the fermionic mass and the coupling constant at finite temperature are discussed. The Gross-Neveu-Yukawa model is studied for AdS4. We also note certain deviations from phases of these theories in flat space.
Stepped partially acoustic dark matter, large scale structure, and the Hubble tension

Published: June 2023

Abstract
We propose a new interacting dark sector model, Stepped Partially Acoustic Dark Matter (SPartAcous), that can simultaneously address the two most important tensions in current cosmological data, the H0 and S8 problems. As in the Partially Acoustic Dark Matter (PAcDM) scenario, this model features a subcomponent of dark matter that interacts with dark radiation at high temperatures, suppressing the growth of structure at small scales and thereby addressing the S8 problem. However, in the SPartAcous model, the dark radiation includes a component with a light mass that becomes non-relativistic close to the time of matter-radiation equality. As this light component annihilates away, the remaining dark radiation heats up and its interactions with dark matter decouple. The heating up of the dark sector results in a step-like increase in the relative energy density in dark radiation, significantly reducing the H0 tension, while the decoupling of dark matter and dark radiation ensures that the power spectrum at larger scales is identical to ΛCDM.

Published: June 2023

ZusammenfassungDie SARS-CoV-2-Pandemie führte zu vielen Infektionen mit dem Virus und Erkrankungen an Coronavirus-Krankheit-2019 (COVID-19). Als Konsequenz davon war ein enormer Anstieg gemeldeter und anerkannter Berufskrankheiten (BK) und Arbeitsunfälle (AU) bei den Berufsgenossenschaften (BG) und Unfallkassen als Träger der Deutschen Gesetzlichen Unfallversicherung zu verzeichnen. Die Publikation hat das Ziel, die Unterschiede von BK oder AU aufzuzeigen und die aktuellen Daten zum BK-Geschehen aufzuarbeiten. Dabei wird auf Definitionen von BK und AU, die Unterschiede in den Voraussetzungen für eine Anerkennung im Sinne einer BK oder eines AU eingegangen. Des Weiteren werden die Leistungsansprüche dargestellt. Zuletzt werden statistischen Kennzahlen der BK nach Nr. 3101 und den AU dargestellt.Ergebnisse (Eckpunkte):– AU und BK sind nach § 7 SGB VII Versicherungsfälle der gesetzlichen Unfallversicherung.– In der Chirurgie wird wie spezifisch im übrigen Gesundheitswesen die Relevanz der SARS-CoV-2-Infektion mit ihrer Post-COVID beim Personal für die arbeitsmedizinische Vorsorge und als anzuerkennender Fall der gesetzlichen Unfallversicherung (BK oder AU) deutlich.– Maßgeblich für die Anerkennung sind die Dauer und die Intensität des Kontaktes (örtliche Nähe) – die SARS-CoV-2-Arbeitsschutzregel vom 20.08.2020 sieht hier im Wesentlichen eine Kontaktdauer von mindestens 15 min bei einer räumlichen Entfernung von weniger als 1,5–2 m vor (weitere Aspekte: intensiverer kürzerer Kontakt, Anzahl der nachweislich infizierten Personen im engeren Tätigkeitsumfeld bzw. der üblichen Personenkontakte, räumliche Situation, Arbeitsweg, besondere Konstellationen).– Für die detaillierte Darstellung des Settings Chirurgie können keine Fallzahlen eruiert werden. – Bei der Begutachtung von COVID-19-Folgen bzw. „Post-COVID“ als BK bestehen noch immense Probleme und Herausforderungen, da zahlreiche Unsicherheitsfaktoren wie z. B. unzureichend gesichertes Wissen zum weiteren Langzeitverlauf über die Jahre oder das breit gefächerte Symptomspektrum die ärztliche Beurteilung der Folgen dieser Erkrankung erschweren.Schlussfolgerung: Die SARS-CoV-2-Pandemie stellt sich als eine besondere Herausforderung der Chirurgie mit fachspezifisch immanent intensiverem Patientenkontakt bzw. des gesamten Gesundheitswesens dar, die durchaus langanhaltende Veränderungen verursachte und deren adäquate gesundheitsbetreuerische wie auch versicherungsrechtliche Aufarbeitung der (fallspezifischen) Konsequenzen noch beträchtliche Anstrengungen und Ressourcen erfordern dürfte.

AbstractBackgroundThe aim of this study was to analyze the impact of an abdominal wall surgery unit on postoperative complications (within 90 days postoperatively), hernia recurrence and chronic postoperative inguinal pain after elective recurrent inguinal hernia repair.MethodsWe conducted a retrospective cohort study of all adult patients who underwent elective recurrent inguinal hernia repair between January 2010 and October 2021. Short‐ and long‐term outcomes were compared between the group of patients operated on in the abdominal wall surgery unit and the group of patients operated on by other units not specialized in abdominal wall surgery. A logistic regression model was performed for hernia recurrence.ResultsA total of 250 patients underwent elective surgery for recurrent inguinal hernia during the study period. The patients in the abdominal wall surgery group were younger (P ≤ 0.001) and had fewer comorbidities (P ≤ 0.001). There were no differences between the groups in terms of complications. The patients in the abdominal wall surgery group presented fewer recurrences (15% vs. 3%; P = 0.001). Surgery performed by the abdominal wall surgery unit was related to fewer recurrences in the multivariate analysis (HR = 0.123; 95% CI = 0.21–0.725; P = 0.021).ConclusionsSpecialization in abdominal wall surgery seems to have a positive impact in terms of recurrence in recurrent inguinal hernia repair. The influence of comorbidities or type of surgery (i.e., outpatient surgery) require further study.

AbstractNanocomposites comprising (V2O5)x. (Mn0.4Fe2.6O4)(2−x), where x = [0.2, 0.4, 0.6, 0.8, and 1], were successfully synthesized by milling each single phase of V2O5 and Mn0.4Fe2.6O4 nanostructured samples. We studied the structure and morphology of the prepared samples through X-ray diffraction and scanning electron microscopy. UV–Vis. spectrum analysis was used to study the optical characteristics. As an attempt to improve the optical and nonlinear optical properties of the PVDF blend, the prepared nanocomposites were used as nanofillers for the poly (vinylidene fluoride) (PVDF) polymer. Optical and nonlinear optical properties of the PVDF polymer were tuned using (V2O5)x. (Mn0.4Fe2.6O4)(2−x), where x = [0.2, 0.4, 0.6, 0.8, and 1] nanocomposite. The obtained results showed a tunable spectrum, absorption, refractive index, and dielectric constant at wavelengths ranging from 200 to 800 nm. However, the results showed that the (V2O5)0.6. (Mn0.4Fe2.6O4)1.4, sample was the best for obtaining the lowest transmittance percentage and bandgap energy. The nonlinear optical properties and Kerr effect (quadratic electro-optic effect) showed a significant response, which can be tuned in the range from 200 to 1200 nm of wavelength using the investigated samples. Finally, incorporating (V2O5)x. (Mn0.4Fe2.6O4)(2−x), where x = [0.2, 0.4, 0.6, 0.8, and 1], nanoparticles in the PVDF polymer improved the hydrophilic behavior of the PVDF films. This study suggests a promising nanocomposite material for tunable optoelectronics and useful polymer membranes.

Abstract
Objective
To examine whether incorrect AI results impact radiologist performance, and if so, whether human factors can be optimized to reduce error.

Methods
Multi-reader design, 6 radiologists interpreted 90 identical chest radiographs (follow-up CT needed: yes/no) on four occasions (09/20–01/22). No AI result was provided for session 1. Sham AI results were provided for sessions 2–4, and AI for 12 cases were manipulated to be incorrect (8 false positives (FP), 4 false negatives (FN)) (0.87 ROC-AUC). In the Delete AI (No Box) condition, radiologists were told AI results would not be saved for the evaluation. In Keep AI (No Box) and Keep AI (Box), radiologists were told results would be saved. In Keep AI (Box), the ostensible AI program visually outlined the region of suspicion. AI results were constant between conditions.

Results
Relative to the No AI condition (FN = 2.7%, FP = 51.4%), FN and FPs were higher in the Keep AI (No Box) (FN = 33.0%, FP = 86.0%), Delete AI (No Box) (FN = 26.7%, FP = 80.5%), and Keep AI (Box) (FN = to 20.7%, FP = 80.5%) conditions (all ps < 0.05). FNs were higher in the Keep AI (No Box) condition (33.0%) than in the Keep AI (Box) condition (20.7%) (p = 0.04). FPs were higher in the Keep AI (No Box) (86.0%) condition than in the Delete AI (No Box) condition (80.5%) (p = 0.03).

Conclusion
Incorrect AI causes radiologists to make incorrect follow-up decisions when they were correct without AI. This effect is mitigated when radiologists believe AI will be deleted from the patient’s file or a box is provided around the region of interest.

Clinical relevance statement
When AI is wrong, radiologists make more errors than they would have without AI. Based on human factors psychology, our manuscript provides evidence for two AI implementation strategies that reduce the deleterious effects of incorrect AI.

Key Points
• When AI provided incorrect results, false negative and false positive rates among the radiologists increased.
• False positives decreased when AI results were deleted, versus kept, in the patient’s record.
• False negatives and false positives decreased when AI visually outlined the region of suspicion.
