AbstractThe quality of cervical spinal cord images can be improved by the use of tailored radiofrequency (RF) coil solutions for ultrahigh field imaging; however, very few commercial and research 7‐T RF coils currently exist for the spinal cord, and in particular, those with parallel transmission (pTx) capabilities. This work presents the design, testing, and validation of a pTx/Rx coil for the human neck and cervical/upper thoracic spinal cord. The pTx portion is composed of eight dipoles to ensure high homogeneity over this large region of the spinal cord. The Rx portion is made up of twenty semiadaptable overlapping loops to produce high signal‐to‐noise ratio (SNR) across the patient population. The coil housing is designed to facilitate patient positioning and comfort, while also being tight fitting to ensure high sensitivity. We demonstrate RF shimming capabilities to optimize B1+ uniformity, power efficiency, and/or specific absorption rate efficiency. B1+ homogeneity, SNR, and g‐factor were evaluated in adult volunteers and demonstrated excellent performance from the occipital lobe down to the T4‐T5 level. We compared the proposed coil with two state‐of‐the‐art head and head/neck coils, confirming its superiority in the cervical and upper thoracic regions of the spinal cord. This coil solution therefore provides a convincing platform for producing the high image quality necessary for clinical and research scanning of the upper spinal cord.

Distributed fusion robust filter for multisensor networked singular control system with uncertain variances and missing measurement
Authors: Zheng Jiayi , Ran Chenjian 
Published: July 2023

AbstractA distributed fusion time‐varying robust filtering algorithm for multisensor networked singular control system is studied in this paper, mainly aiming at the system with missing measurement and uncertain variances in practical application. First, the singular value decomposition (SVD) method and de‐randomization method are used to transform the singular control system into a standard system only with uncertain variances. Based on the new standard system, a minimax robust local Kalman filter is proposed by using the minimax robust estimation principle, which ensures that the actual filtering error variance has the corresponding minimum upper bound for all allowable uncertainties. Further, the robust local and distributed fusion filters for original singular control systems are proposed, and the actual and conservative filtering error variances are obtained. Their robustness is proved by Lyapunov equation method and nonnegative definite matrix decomposition method. A simulation example of two‐loop system verifies the effectiveness of the proposed results.

Published: July 2023

AbstractBackgroundAspergillus niger is generally considered safe and is widely used across a broad range of industries from food to pharmaceuticals. The metabolites of some Aspergillus species are effective in killing nematodes. The active ingredients that play a role are citric acid and oxalic acid.ResultsThe effective nematocidal metabolite in the fermentation broth of the A. niger Ym16 is a calcium oxalate coordination compound (C2H2O4•2(C2HO4)•C2O4•4(H2O)•2(Ca)). The mortality of fermentation broth and compound solution to second‐stage juveniles (J2s) of Meloidogyne incognita were 94% (8 h) and 95% (2 h), respectively. The hatching inhibition rates of fermentation broth and compound solution to eggs of M. incognita were 86% (24 h) and 87% (12 h), respectively. Furthermore, the Ym16 strain promoted plant growth.ConclusionStrain Ym16 and its metabolites should be the first choice for nematode control because it is an effective agent against soil nematodes. © 2023 Society of Chemical Industry.
Medicinal plant molecules against hepatitis C virus: Current status and future prospect
Authors: Mandal Anirban , Hazra Banasri 
Published: July 2023

AbstractHepatitis C virus (HCV), a global malady, causes acute and chronic hepatitis leading to permanent liver damage, hepatocellular carcinoma, and death. Modern anti‐HCV therapies are efficient, but mostly inaccessible for residents of underdeveloped regions. To innovate more effective treatments at affordable cost, medicinal plant‐based products need to be explored. The aim of this article is to review plant constituents in the light of putative anti‐HCV mechanisms of action, and discuss existing problems, challenges, and future directions for their potential application in therapeutic settings. One hundred sixty literatures were collected by using appropriate search strings via scientific search engines: Google Scholar, PubMed, ScienceDirect, and Scopus. Bibliography was prepared using Mendeley desktop software. We found a substantial number of plants that were reported to inhibit different stages of HCV life cycle. Traditional medicinal plants such as Phyllanthus amarus Schumach. and Thonn., Eclipta alba (L.) Hassk., and Acacia nilotica (L.) Delile exhibited strong anti‐HCV activities. Again, several phytochemicals such as epigallocatechin‐3‐gallate, honokilol, punicalagin, and quercetin have shown broad‐spectrum anti‐HCV effect. We have presented promising phytochemicals like silymarin, curcumin, glycyrrhizin, and camptothecin for nanoparticle‐based hepatocyte‐targeted drug delivery. Nevertheless, only a few animal studies have been performed to validate the anti‐HCV effect of these plant products. Again, insufficient clinical evaluation of the safety and effectiveness of herbal medications remain a problem. Selected plants products could be developed as novel therapeutics for HCV patients only after scrupulous evaluation of their safety and efficacy in a clinical set‐up.
A conceptual model for food industry views on the commercialisation of active and intelligent packaging
Authors: Young Erin , Mirosa Miranda , Bremer Phil 
Published: July 2023

AbstractThis paper presents a conceptual model, identifying the factors that impact the supply chain commercialisation of active and intelligent packaging across various food product types. The model was derived from interviews conducted with marketing and technical personnel across various food exporters, packaging manufacturers, relevant government agents and industry bodies with global perspectives based in New Zealand. The conceptual model theorises the relationships among the macro, sector and business factors that characterise an organisation, the perceived benefits of commercialising active or intelligent packaging, and the perceived barriers preventing commercialisation. Interactions between commercialising active and intelligent packaging and needing to meet packaging sustainability objectives were also identified. Developers of active and intelligent packaging can utilise the findings of this research to prioritise and refine their innovations better to suit the industry's needs within a sustainability framework.

Published: July 2023

AbstractBackgroundSingle‐entry models (SEM) improve wait times for hip and knee replacement, but little is known whether prioritization implemented in SEM can help meet the benchmarks for consolation/surgery. This study aimed to determine the impact of prioritization on receiving consultation and surgery within the benchmarks.MethodsThis is a retrospective cohort study for which two administration databases were linked. Logistic regression was used to investigate the impact of prioritization on receiving consultations and surgery within the benchmarks of 90 and 182 days, respectively, adjusting for patients’ characteristics and preference for surgeon.Results1,967 patients were included in this study. The odds ratios of having consultation within 90 days for hip replacement patients in priorities 1 and 2 (high priority) were 57.24 (CI: 23.16–141.47) and 14.63 (CI: 6.44–33.25), respectively, compared with those in priority 3. For knee replacement, patients with higher priority were more likely to have consultation within 90 days. Although priority levels were not related to having surgery within 182 days for knee replacement, hip replacement patients with priority 1 (CI: 0.2–0.75) and 2 (CI: 0.16–0.54) were less likely to have surgery within 182 days, compared with those with priority 3.ConclusionPatients with high priority levels were more likely to have consultation within 90 days for hip and knee replacements. SEM may not help have surgery within 182 days. Prioritization has no impact on receiving surgery within 182 days for knee replacement, but hip replacement patients with high priority were less likely to have surgery within 182 days.

Published: July 2023

AbstractThis paper investigates the dynamical properties of the spin‐coupling ensemble, with a focus on the spin‐decoupling phenomenon. The nuclear spin in such systems is significantly impacted by the electron spin when the main magnetic field approaches the Fermi contact field of nuclear spin, leading to measurement inaccuracies. A comprehensive dynamics model of the electron‐nuclear spin coupling ensemble has been established and analyzed. It proposes that the primary magnetic field augmenting effectively disentangles the precession frequency of the two spin‐coupling species, thereby yielding a spin‐decoupled state. Such a state allows nuclear spin serves as a high sensitive element for magnetic field measurements, while electron spin serves as a probe to acquire the precession of nuclear spin. With proposed method, a magnetic field resolution of 0.75 nT in a 12000 nT environment is achieved, indicating potential for magnetic field detection in geomagnetic environments. It further demonstrates measurements of electron spin Fermi contact interaction and polarization based on spin‐decoupling and in situ nuclear spin precession, results indicate measurement errors close to 1%. These results demonstrate the effectiveness of our approach in improving the accuracy and sensitivity of magnetic field measurements in spin‐coupled systems such as co‐magnetometers, nuclear magnetic resonance gyroscopes, and nuclear magnetometers.
Towards low‐carbon sustainable development under Industry 4.0: The influence of industrial intelligence on China's carbon mitigation

Published: July 2023

AbstractGlobal climate change is becoming an increasingly serious issue. China, the largest carbon emitter, has a long way towards its sustainable development goals (SDGs) and take on its carbon reduction responsibility, especially in the industrial sector. In this vein, industrial intelligence, a key driver in the “Industry 4.0 era”, offers an opportunity in this carbon reduction campaign. This paper seeks to examine the influences of industrial intelligence on carbon emissions, their heterogeneous characteristics and transmission mechanisms, and the moderating role of human capital. Therefore, we properly probed theoretical aspects, and then we used China's provincial data from 2006 to 2019 and a number of tests, namely the fixed effect model, the two‐stage test, and the moderating effect model, to test the relevant assumptions. We first unfolded that industrial intelligence can significantly mitigate carbon emissions. Specifically, the heterogeneous analysis found that carbon reduction efforts are more pronounced in China's central and western regions and resource‐based regions. We further highlight the mechanism identification, which reveals that industrial structure upgrading and technological innovation are the main channels for industrial intelligence to abate CO2 emissions. Importantly, we pinpoint the role of human capital, which positively moderates the relationship between industrial intelligence and carbon emissions and can well amplify the industrial structure effect of industrial intelligence. These results are conducive to accurately assessing the environmental benefits of industrial intelligence and providing policy enlightenment for China to alleviate carbon emissions, and they will also offer a reference for other developing countries to learn from.

Published: July 2023

AbstractMolybdenum carbides are promising low‐cost electrocatalysts for electrolyzers, fuel cells, and batteries. However, synthesis of ultrafine, phase‐pure carbide nanoparticles (diameter < 5 nm) with large surface areas remains challenging due to uncontrollable agglomeration that occurs during traditional high temperature syntheses. This work presents a scalable, physical approach to synthesize molybdenum carbide nanoparticles at room temperature by ion implantation. By tuning the implantation conditions, various molybdenum carbide phases, stoichiometries, and nanoparticle sizes can be accessed. For instance, molybdenum ion implantation into glassy carbon at 30 keV energy and to a fluence of 9 × 1016 at cm−2 yields a surface η‐Mo3C2 with a particle diameter of (10 ± 1) nm. Molybdenum implantation into glassy carbon at 60 keV to a fluence of 6 × 1016 at cm−2 yields a buried layer of ultrafine γ’‐MoC/η‐MoC nanoparticles. Carbon ion implantation at 20 keV into a molybdenum thin film produces a 40 nm thick layer primarily composed of β‐Mo2C. The formation of nanoparticles in each molybdenum carbide phase is explained based on the Mo‐C phase diagram and Monte‐Carlo simulations of ion‐solid interactions invoking the thermal spike model. The approaches presented are widely applicable for synthesis of other transition metal carbide nanoparticles as well.
The last horned armadillos: phylogeny and decline of Peltephilidae (Xenarthra, Cingulata)

Published: July 2023

AbstractPeltephilidae (Xenarthra, Cingulata) is an ancient lineage of medium–large‐sized ‘armadillos’ from South America, characterized by chisel‐shaped molariforms, a U‐shaped dental arcade, and cephalic osteoderms modified into hornlike structures. Although the biochron of the group extends from the early Eocene to the Late Miocene, the most abundant and complete records come from the Early Miocene of Patagonia. Remains from the Late Miocene are very scarce, and the last records of the group are from the Chasicoan Stage (Tortonian). The only taxon known from this interval is Epipeltephilus kanti from the Arroyo Chasicó Formation (9.23 ± 0.09 Ma; Buenos Aires Province, Argentina), a species previously represented only by a few isolated osteoderms. Here we report new remains assigned to E. kanti from the Late Miocene of Loma de Las Tapias Formation (c. 9.0–7.8 Ma; San Juan Province, Argentina), including a hemimandible and several fixed and mobile osteoderms. These new specimens constitute the youngest record of Peltephilidae. The inclusion of E. kanti within Epipeltephilus and the monophyly of the genera Peltephilus and Epipeltephilus are corroborated for the first time through a cladistic analysis. The decline and eventual disappearance of this ‘armadillo’ group in the Late Miocene is chronologically coincident with the replacement of subtropical/tropical environments by more open and arid ones and with the proliferation of other large armadillos such as Vetelia, Macrochorobates, and Macroeuphractus.

Published: July 2023

ZusammenfassungDie Protokollbücher der Kabinettskanzlei werden als Ausgangspunkt verwendet, um einen ethnographisch inspirierten Blick auf die Regierungstätigkeit von Kaiser Franz Joseph zu richten. Der Wirklichkeitsbezug des Monarchen war durch schriftliche Vorträge bestimmt, die bis zum Schreibtisch des Kaisers mehrere Instanzen durchliefen. Ein Sachverhalt wurde beim Weg durch die Instanzen mehrfach  übersetzt  und transformiert. In diesem Beitrag interessiere ich mich für den kritischen Umgang des Kaisers und seiner Kanzlei mit diesen komplex strukturierten Texten, die den Ausgangspunkt für eine Entscheidungstätigkeit bildeten.

ZusammenfassungDer Text diskutiert die Frage des Protokolls als Frage nach Praxisformen des Beobachtens und konzentriert sich dabei nicht allein auf Entscheider, deren Entscheidungen der protokollarischen Ordnung bedürfen, sondern auf das kommunikative Substrat der Protokolle, auf Mündlichkeit, Geselligkeit, Informalität. Besondere Relevanz haben diese informalen Organisationsvarianten in Anstaltsorganisationen, wie sie vor allem in professionalisierten Kontexten zu finden sind. Eine Anschlussüberlegung, die auch als Ausblick auf ein Forschungsinteresse zu verstehen ist, widmet sich dem Übergreifen dieser Anstaltsform auf Alltagssozialität; das Protokollarische wird hier zu einer ekstatischen Mitschrift, praktiziert in unpersönlicher Attitüde.
Shift Symmetries and AdS/CFT
Authors: Blauvelt Erin , Engelbrecht Laura , Hinterbichler Kurt 
Published: July 2023

Abstract
Massive fields on anti-de Sitter (AdS) space enjoy galileon-like shift symmetries at particular values of their masses. We explore how these shift symmetries are realized through the boundary conformal field theory (CFT), at the level of the 2-point functions. In the alternate quantization scheme in which the dual conformal field gets the smaller ∆− conformal dimension, the shift symmetry is realized as a gauge symmetry in the dual CFT, so that only shift invariant operators are true conformal primary fields. In the standard quantization scheme the shift symmetry acts on the source, leading to Ward identities that take the form of integral constraints.
A layerwise monitoring methodology based on blue laser line profilometer for Material Extrusion processes

Published: July 2023

AbstractMaterial Extrusion (MEX) is an Additive Manufacturing technology widely used for the fabrication of polymeric, metallic and composite parts with clear advantages. In the last decades, the growing interest of such industries like aerospace, medical, automotive and R&D has driven technological improvements of MEX to make the technology more reliable and repeatable. Although, defects and geometric dimensional inaccuracies are still known to affect the process, limiting the applicability of MEX for the realization of functional parts. Recently, in-process monitoring methods have been implemented for a rapid detection of defects and process anomalies, activating, eventually, the control of the process. In this work, an innovative layerwise monitoring methodology based on a high-resolution blue laser line profilometer applied to a MEX process, was proposed. By analyzing the point clouds of each layer, with proper quality indexes, it was possible to compute the layer height deviation and to evaluate the surface quality in terms of occurrence of defects. In particular, the quality indexes presented in this work were representative of the layer height accuracy, the occurrence and distribution of defects on the layer surface and the stability of the process (respectively the so-called indexes were ADLH, RAD and the slope s). Different process conditions were generated by varying the raster angle and the sample location on the building platform.
Submerged arc welding process: a numerical investigation of temperatures, displacements, and residual stresses in ASTM A516-Gr70 corner joined samples
Authors: Conte Romina , Izquierdo David Rodríguez , Francesco Gagliardi 
Published: July 2023

AbstractArc welding processes represent an important category of fusion welding techniques. They are characterised by the use of an electric arc to create heat to melt and join metals. Submerged arc welding belongs to this process category. Its peculiarities are mainly related to the employment of a continuously fed electrode and of a powdered flux to cover the arc providing electrical conduction between electrode and metals to be connected and, at the same time, generating protective gas and slag shields. Current ($$I$$
I
), voltage ($$V$$
V
), and welding speed ($$v$$
v
) are the main process variables, properly set, to guarantee the specific heat (SH) required to achieve sound weld beads. In this research, finite element models were built looking at the macrographs extracted by experimental tests performed in two steps in order to obtain the real area of each pass and setting different welding conditions. Different combinations of $$I$$
I
, $$V$$
V
, and $$v$$
v
were proposed providing, however, a fixed SH to the welding zone according to the required industrial standards. Specifically, tests were executed increasing the ratio V to v (for a constant $$I$$
I
) and the ratio $$I$$
I
to $$v$$
v
(for a constant $$V$$
V
) and with a different combination of $$V$$
V
and $$I$$
I
maintaining constant their product (for a constant $$v$$
v
). The influence of the investigated variables’ combination on the weld pool in terms of depth and width was discussed. Finally, the validated numerical models were employed to highlight precisely residual stresses and displacements trend on cross-sectioned weld beads connecting the shown tendencies to the investigated process conditions.
