Published: May 2023

AbstractWith the rapid development of advanced materials and manufacturing technologies, flow sensors have made significant progress in the field of mechanical engineering, which could cater to the development trend of the Internet of Things (IoT) and the ongoing Fourth Industrial Revolution. However, traditional power supply modes such as lithium batteries require regular recharging or replacement, which greatly causes too much inconvenience and maintenance consumption, and may also pose potential risks to the marine environment. The triboelectric nanogenerators (TENGs), based on the coupling effect of contact electrification and electrostatic induction, have been demonstrated to convert mechanical movements of the fluid into electrical signals with various features such as flexibility, conformability, and user‐friendliness. This review systematically summarizes for the first time the fundamental working mechanism, rational structural design, and analysis of practical application scenarios of triboelectric flow sensor as an emerging technology for flow monitoring of the Industrial IoT. According to the different fluid objects monitored, the latest representative achievements of triboelectric flow sensors can be divided into gas flow sensors, liquid flow sensors, and two‐phase flow sensors. Finally, the current challenges and future development directions of triboelectric flow sensors are examined, which can promote the further development of the field of the flow sensors.

AbstractDeveloping radical‐induced afterglow emission under ambient conditions is challenging since newly formed radical species are susceptible to air and water. In this work, long afterglow materials (up to 4 s) are realized by doping a series of N,N’‐diaryl‐5,10‐dihydrophenazine (DPP)derivatives into rigid cycloaliphatic epoxy resins (CER). The afterglow is found to result from the interaction between the matrix and the excited states of the dopants through the generation of radical species under continuous UV excitation, which can be regulated by the peripheral functional groups of the N‐phenyl substituents. Density functional theory (DFT) calculations predict that the introduction of electron‐withdrawing groups hinders the afterglow emission, which may be related to the reducing reduction potential and inefficient spin‐orbit coupling (SOC) coefficients. The afterglow emission of the radical‐based systems demonstrates a bright opportunity for information encryption, anti‐counterfeiting, and photolithography.

Published: May 2023

AbstractAs the demand for lithium‐ion batteries (LIBs) continuously grows, the necessity to improve their efficiency/performance also grows. For this reason, optimization of the individual production steps is critical. Calendering is a crucial production step whereby electrode coatings are compacted to targeted densities. This process affects the porosity, adhesion, thickness, wettability, and charge transport properties of the electrodes, as well as the homogeneity of the coatings. Optimal calendered electrodes improve volumetric energy density, cyclic stability, and rate capability of the cells and also enhance the structural stability of the active material, which affects electrode safety and polarization. This article outlines the fundamental processes and mechanisms, as well as how modeling, simulation, and tomography can be used to optimize these processes. Additionally, the influence of calendering on a wide range of anode and cathode active materials is discussed. This review serves to give a deeper understanding into the calendering process‐structure‐performance relationships, and how they can be optimized to improve the performance of LIBs.
Advances in Searching for Galactic Axions with a Dielectric Haloscope (MADMAX)
Authors: Gardikiotis Antonios ,   MADMAX Collaboration
Published: May 2023

AbstractAxions are hypothetical particles that could explain the observed dark matter density and, simultaneously, could naturally resolve the strong charge parity (CP) problem in quantum chromodynamics (QCD). Recent theoretical works indicate that axions are expected to have masses in the range of , a range that presently still evades experimental detection. An experimental design is presented to search for QCD axions in this mass range via the magnetized disk and mirror axion experiment (MADMAX). MADMAX will be composed of multiple movable dielectric disks and a stable mirror that are placed inside a strong magnetic field to utilize the axion‐induced coherent electromagnetic wave emissions from each disk surface. In this paper, new R&D milestones achieved will be reported, that is, the updated magnet quench protection system, a closed booster dielectric haloscope system tested in the MORPURGO magnet at (European Organization for Nuclear Research) CERN using a full experimental data acquisition chain. These new main novel accomplishments investigate the feasibility of the experiment.
A Perioperative Specialty Elective to Address the Perioperative Nursing Shortage: Student Perspectives and Outcomes
Authors: Reuter Jessica , Spalla King Tara 
Published: May 2023

ABSTRACTTo help solve the perioperative nursing shortage, it is imperative that health care leaders understand why students choose or do not choose to pursue a career in perioperative nursing. In May 2021, we published the results of a specialty elective course evaluation from a leadership and perioperative services personnel perspective; in the current article, we examine the same program from the students’ perspective. We distributed survey links to undergraduate nursing students to evaluate their perioperative knowledge before and after completing the course. Students reported large gains in knowledge, critical thinking, teamwork, and confidence at course completion, but the posttest mean number of students with an interest in pursuing perioperative nursing was lower than the pretest mean. This realization is perceived as a positive outcome of the perioperative elective course because it may lead to a decrease in turnover among newly hired perioperative nurses.
Optimal portfolio with relative performance and partial information: A mean‐field game approach
Authors: Zhang Panpan , Huang Pengyan 
Published: May 2023

AbstractWe use a mean‐field game (MFG) formulation to investigate a family of portfolio management problems with relative performance in a partially observable financial market. The stock price process is characterized by a factor model and investors can only observe past stock price data. All investors share a common investment period and have constant absolute risk aversion (CARA) utility functions. We construct explicit linear feedback equilibria for both a finite population game and a corresponding MFG. Filtering theory and dynamic programming method are involved to solve two kinds of optimization problems with partial information. Our results show that the limiting strategy for
‐agent game can be derived as equilibrium of suitable MFG in a partially observable financial market.

Published: May 2023

AbstractMore than half of licensed therapeutic recombinant proteins (r‐proteins) are manufactured using constitutively‐expressing, stably‐transfected Chinese hamster ovary (CHO) clones. While constitutive CHO expression systems have proven their efficacy for the manufacturing of monoclonal antibodies, many next‐generation therapeutics such as cytokines and bispecific antibodies as well as biological targets such as ectodomains of transmembrane receptors remain intrinsically challenging to produce. Herein, we exploited a cumate‐inducible CHO platform allowing reduced expression of various classes of r‐proteins during selection of stable pools. Following stable pool generation, fed‐batch productions showed that pools generated without cumate (OFF‐pools) were significantly more productive than pools selected in the presence of cumate (ON‐pools) for 8 out of the 10 r‐proteins tested, including cytokines, G‐protein coupled receptors (GPCRs), the HVEM membrane receptor ectodomain, the multifunctional protein High Mobility Group protein B1 (HMGB1), as well as monoclonal and bispecific T‐cell engager antibodies. We showed that OFF‐pools contain a significantly larger proportion of cells producing high levels of r‐proteins and that these cells tend to proliferate faster when expression is turned off, suggesting that r‐protein overexpression imposes a metabolic burden on the cells. Cell viability was lower and pool recovery was delayed during selection of ON‐pools (mimicking constitutive expression), suggesting that high producers were likely lost or overgrown by faster‐growing, low‐producing cells. We also observed a correlation between the expression levels of the GPCRs with Binding immunoglobulin Protein, an endoplasmic reticulum (ER) stress marker. Taken together, these data suggest that using an inducible system to minimize r‐protein expression during stable CHO pool selection reduces cellular stresses, including ER stress and metabolic burden, leading to pools with greater frequency of high‐expressing cells, resulting in improved volumetric productivity.

Published: May 2023

AbstractSkin wounds, such as burns, diabetic foot ulcers, pressure sores, and wounds formed after laser or surgical treatment, comprise a very high proportion of dermatological disorders. Wounds are treated in a variety of ways; however, some wounds are greatly resistant, resulting in delayed healing and an urgent need to introduce new alternatives. Our previous studies have shown that cold atmospheric plasma (CAP) has antibacterial activity and promotes cell proliferation, differentiation, and migration in vitro. To further advance the role of CAP in wound healing, we evaluated the safety and efficacy of CAP in vitro by irradiation of common refractory bacteria on the skin, irradiation of normal skin of rats and observing reactions, treatment of scald wounds in rats, and treating clinically common acute wounds. Our findings revealed that CAP can eliminate refractory skin bacteria in vitro; CAP positively affected wound healing in a rat scalding wound model; and direct CAP irradiation of low intensity and short duration did not lead to skin erythema or edema. CAP promises to be a new, economical, and safe means of wound treatment.

AbstractTwo new glycerolipids, syngaculipids A and B (1 and 2), one first naturally occurring metabolite (8), together with five known compounds (3–7) were isolated from the AcOEt fraction of Syngnathus acus L. (Hai‐Long). Their structures were elucidated by comprehensive spectral analyses involving UV, IR, MS, 1D and 2D NMR spectra and ECD calculations. All the isolated compounds were evaluated for their cytotoxicity against A549 and HCT‐116 cell lines. Compound 8 exhibited moderate cytotoxicity with IC50 values of 34.5 and 38.9 μM on the A549 and HCT‐116 cell lines, respectively.

One year after completion of adjuvant radiotherapy, the patient remains disease‐free.
OQ‐IICA: Optimal QoS‐aware intra‐inter cluster data aggregation technique for IoT‐assisted WSNs using hybrid optimization techniques
Authors: Monica Satyavathi D. , Sudhir A. Ch. 
Published: May 2023

SummaryThe wireless sensor network (WSN) contains sensor nodes for understanding, communicating, and storing battery capacity data. Data collection can be defined as the process that base stations use to eliminate unwanted transmissions and provide mixed information. This improves energy efficiency and extends the life of low‐energy WSNs enabled by IoT (IoT‐WSNs). In this article, we propose an optimal QoS‐aware intra‐inter cluster data aggregation technique for WSNs using hybrid optimization techniques (OQ‐IICA). First, we introduce a modified bowerbird optimization (MBO) algorithm for balanced clustering which improves energy efficiency. Second, we develop a multi‐objective seagull optimization‐based decision‐making (MSO‐DM) algorithm to estimate the CH of clusters in the network. Next, we introduce a teacher‐inspired cappuccino search algorithm to ensure the quality of data transfer between nodes by learning through internal and cluster routing. Finally, the proposed OQ‐IICA algorithm compares the latest technologies in ICA, Leach, and Leach‐C power consumption, latency, throughput, latency, number of live nodes, routing, and grid length.
Homoleptic Alkynylpyridinium Au(I) Complexes as Organometallic ‘D‐π‐A’ Chromophores

Published: May 2023

AbstractA series of terminal acetylenes bearing methylpyridinium acceptor group attached to the alkynyl unit with different π‐conjugated aromatic linker have been synthetized. These alkynylpyridinium salts are efficient ‘push‐pull’ chromophores demonstrating bright UV‐vis fluorescence with quantum yields up to 70 %. The homoleptic bis‐alkynyl Au(I) complexes based on these alkynylpyridinium ligands demonstrate complicated photophysical behavior including dual emission in solution. The variation of the linker allows one to tune the intrasystem charge transfer and thus to change the electronic and photophysical properties of the organogold ‘D‐π‐A’ system. This study demonstrates that absolute and relative intensities of the bands in emission spectra and their energies are responsive to solvent system and anion nature even in case of weakly coordinative anions. TDDFT calculations show that the transitions related to emission of the complex cations are strongly associated with the hybrid MLCT/ILCT charge transfer, thus demonstrating that the complex molecule acts as a unified ‘D‐π‐A’ system.

Published: May 2023

AbstractCo‐occurring carnivore species that are phylogenetically related or of similar size, morphology, and ecological needs often reduce competition by partitioning shared resources through temporal, spatial, and dietary niche segregation via behavioral adaptations. Caracals (Caracal caracal) and jungle cats (Felis chaus) co‐occur in portions of their geographical ranges and are expected to display resource segregation in these ranges. We compiled scat, stomach content, and prey remains found data from published and unpublished sources to summarize information on the diets of caracals and jungle cats across their geographical ranges during 1842–2021. We obtained 63 sources from 26 countries in Europe, Asia, and Africa, in which caracal diet included 151 species while jungle cat diet included 61 species. We found that caracals and jungle cats did not exhibit dietary niche partitioning and had greater dietary similarities in areas of range overlap. We also found that caracals consumed more diverse prey species including prey with greater average body mass compared to jungle cats. Our results suggest that greater prey diversity in areas of range overlap, caracal predation on wide range of prey, and opportunistic feeding behavior that facilitates consumption of more diverse prey species compared to jungle cats, may facilitate co‐occurrence between these two felid species.

Published: May 2023

AbstractNoninvasive genetic sampling greatly facilitates studies on the genetics, ecology, and conservation of threatened species. Species identification is often a prerequisite for noninvasive sampling‐based biological studies. Due to the low quantity and quality of genomic DNA from noninvasive samples, high‐performance short‐target PCR primers are necessary for DNA barcoding applications. The order Carnivora is characterized by an elusive habit and threatened status. In this study, we developed three pairs of short‐target primers for identifying Carnivora species. The COI279 primer pair was suitable for samples with better DNA quality. The COI157a and COI157b primer pairs performed well for noninvasive samples and reduced the interference of nuclear mitochondrial pseudogenes (numts). COI157a could effectively identify samples from Felidae, Canidae, Viverridae, and Hyaenidae, while COI157b could be applied to samples from Ursidae, Ailuridae, Mustelidae, Procyonidae, and Herpestidae. These short‐target primers will facilitate noninvasive biological studies and efforts to conserve Carnivora species.
Evaluating impacts of non‐native submerged aquatic vegetation on native nekton

Published: May 2023

AbstractThe introduction and spread of non‐native species restructure native ecosystems and can be particularly impactful when invaders are ecosystem engineers or habitat‐forming species. In coastal, estuarine, and marine systems, submerged aquatic vegetation (SAV), like macroalgae and seagrasses, form key habitats for nekton, serving as nurseries, foraging grounds, and reproduction sites. If non‐native ecosystem engineers can provide sufficient structure and/or resources, they may exert a neutral or positive effect on organisms occupying higher trophic positions. As such, we hypothesized that nekton response to non‐native SAV species may be neutral or positive. We performed a quantitative meta‐analysis to quantify impacts of non‐native SAV on native crabs, fishes, and shrimps. We extracted data from 35 studies and evaluated 11 response metrics related to facilitation (e.g., habitat use and foraging), restricting our analysis to studies that compared at least one of these metrics in nekton from co‐occurring native and non‐native SAV habitats in marine, coastal, or estuarine systems. We found that nekton abundance, species richness, and biomass were the most assessed metrics of nekton performance. Our pooled data revealed differential results among response metrics, with nekton growth and reproduction enhanced in non‐native habitats and species richness enhanced in a native setting. The mean effect sizes for all other nekton response metrics, including abundance, had 95% CIs that overlapped zero, indicating no difference in response between native and non‐native SAV. For many endpoints, limited sample sizes prevented robust inferences, but they also highlighted areas where more research is needed in future studies. Non‐native species have the potential to restructure the systems they invade. Our results lend support to the relative trophic position hypothesis, indicating that non‐native habitat formers may facilitate native organisms in higher trophic levels. We identify research gaps that may guide future studies and allow for a more comprehensive understanding of responses to non‐native ecosystem engineers.
A scoping review of recent advances in the application of comet assay to Allium cepa roots
Authors: Alias Carlotta , Zerbini Ilaria , Feretti Donatella 
Published: May 2023

AbstractThe comet assay is a sensitive method for the evaluation of DNA damages and DNA repair capacity at single‐cell level. Allium cepa is a well‐established plant model for toxicological studies. The aim of this scoping review was to investigate the recent application of the comet assay in Allium cepa root cells to assess the genotoxicity. To explore the literature a search was performed selecting articles published between January 2015 and February 2023 from Web of Science, PubMed, and Scopus databases using the combined search terms “Comet assay” and “Allium cepa”. All the original articles that applied the comet assay to Allium cepa root cells were included. Of the 334 records initially found, 79 articles were identified as meeting the inclusion criteria. Some studies reported results for two or more toxicants. In these cases, the data for each toxicant were treated separately. Thus, the number of analyzed toxicants (such as chemicals, new materials, and environmental matrices) was higher than the number of selected papers and reached 90. The current use of the Allium‐comet assay seems to be directed towards two types of approach: the direct study of the genotoxicity of compounds, mainly biocides (20% of analyzed compounds) and nano‐ and microparticles (17%), and assessing a treatment's ability to reduce or eliminate genotoxicity of known genotoxicants (19%). Although the genotoxicity identified by the Allium‐comet assay is only one piece of a larger puzzle, this method could be considered a useful tool for screening the genotoxic potential of compounds released into the environment.
