Abstract

Objective
We evaluated the effect of a 381-mm minimum length limit (MLL) on saugeye (female Walleye Sander vitreus × male Sauger S. canadensis) population and fishery characteristics implemented in Ohio reservoirs in 2011.

Methods
Using a before-after–control-impact study design (n = 6 control populations and n = 11 impact populations that received the MLL), we compared total CPUE, age-2+ CPUE, proportional stock density-harvestable (381-mm), and length at age 2 (to index growth) determined from standardized gill-net surveys and saugeye angler effort, catch rate, harvest rate, length of saugeye at harvest, yield, and satisfaction obtained from standardized creel surveys.

Result
We found evidence that the 381-mm MLL led to an increase in age-2+ CPUE but had no effect on other saugeye population metrics. In the regulation reservoirs, harvest rates declined following MLL implementation. Total length of harvested saugeye did not increase significantly in response to the MLL, and combined with decreased harvest rates, yield was suppressed in the regulation reservoirs relative to the control reservoirs. However, over 90% of anglers reported that they were satisfied with the MLL during creel surveys.

Conclusion
Despite marginal influence on saugeye populations and failure to increase yield, anglers supported the MLL. Our results suggest that the effects of harvest regulations may be marginal, and managers should consider the nuances of angler satisfaction in regulation decisions.

AbstractThe textile industries are looking forward to sustainable textile products. The bio‐based products are very important for protecting the environment, reducing carbon emissions, eliminating chemical pollution, and preserving the resources. These products provide economic advantages and strengthen communities with customer expectations for environmentally friendly items. In addition, sustainable practices encourage innovation and contribute to a healthier and adaptable environment, making them an essential textile product. Here the natural flax fiber plays a vital role due to its eco‐friendly behavior. Cotton‐flax blended yarns are manufacturing for perfect use of natural fibers and getting the better quality yarn than single product yarn. Here in this work it was trying to find out the perfect blending ratio by using Design‐Expert software. Because different blended ratio contain different characteristics. So it was trying to find out a perfect blending solution from the thirteen different ratios by using Design‐Expert software. This software analyses the blended ratios through statistical analysis. This study focuses on the unevenness (U%), imperfection index (IPI), hairiness (H%), tenacity (cN/tex) and elongation at break of the blended yarn. During the analysis the actual and predicted values were checked and it shows good significance, the correlation and regression analysis highlight the results of the samples summary. The findings of the study have great impact on the quality of cotton‐flax blended yarn, which impact on the quality of textile products. This work not only helps to understand cotton‐flax blending using Design‐Expert software, but it also highlights the possibility of using the perfect blended ratio by giving a solution.Highlights

AbstractNa metal batteries are regarded as an encouraging route for energy‐dense and low‐cost battery systems. However, the unstable and irreversible Na plating/stripping, caused by the uncontrolled dendritic Na growth, prevents their practical applications. Herein, a two‐dimensional sp2‐carbon‐linked covalent organic framework (cyano‐sp2c‐COF) is adopted as seeding/hosting coating layer for a highly stable interface with long cycling life, large capacity, and high Na utilization. Benefit from the features of a fully π‐conjugated structure and well‐defined cyano groups, cyano‐sp2c‐COF with superior sodiophilicity and small interface resistance can reduce the nucleation barrier, enable Na ion flux uniformity, and enhance interface stability. Ultimately, the system achieves a low nucleation overpotential of only 10 mV, a remarkable average Coulombic efficiency of 99.7% maintained over 500 cycles in half cells, and exceptional interfacial durability of 8500 h with a high accumulated capacity of 8.5 Ah cm−2 in symmetric cells. Furthermore, the symmetric cells also present a steady cycling, even increasing the depth of discharge up to 90%. As proof, full cells demonstrate a long lifespan enduring 2700 cycles with tiny capacity decay, providing valuable insights into the long‐life Na batteries.

Published: April 2024

AbstractLow‐strain cyclic olefin monomers, including five‐membered, six‐membered, eight‐membered, and macrocyclic rings, have been recently exploited for the synthesis of depolymerizable polyolefins via ring‐opening metathesis polymerization (ROMP). Such polyolefins can undergo ring‐closing metathesis depolymerization (RCMD) to regenerate their original monomers. Nevertheless, the depolymerization behavior of polyolefins prepared by ROMP of seven‐membered cyclic olefins, an important class of low‐strain rings, still remains unexplored. In this study, we demonstrate the chemical recycling of polyheptenamers to cycloheptene under standard RCMD conditions. Highly efficient depolymerization of polyheptenamer was enabled by Grubbs' second‐generation catalyst in toluene. It was observed that the monomer yields increased when the depolymerization temperature increased and the starting polymer concentration was reduced. A near‐quantitative monomer regeneration (>96%) was achieved within 1 h under dilute conditions (20 mM of olefins) at 60°C. Moreover, polyheptenamer exhibited a decomposition temperature above 430°C, highlighting its potential as a new class of thermally stable and chemically recyclable polymer materials.
Structural studies of a serum amyloid A octamer that is primed to scaffold lipid nanodiscs
Authors: Nady Asal , Reichheld Sean E. , Sharpe Simon 
Published: April 2024

AbstractSerum amyloid A (SAA) is a highly conserved acute‐phase protein that plays roles in activating multiple pro‐inflammatory pathways during the acute inflammatory response and is commonly used as a biomarker of inflammation. It has been linked to beneficial roles in tissue repair through improved clearance of lipids and cholesterol from sites of damage. In patients with chronic inflammatory diseases, elevated levels of SAA may contribute to increased severity of the underlying condition. The majority of circulating SAA is bound to lipoproteins, primarily high‐density lipoprotein (HDL). Interaction with HDL not only stabilizes SAA but also alters its functional properties, likely through altered accessibility of protein–protein interaction sites on SAA. While high‐resolution structures for lipid‐free, or apo‐, forms of SAA have been reported, their relationship with the HDL‐bound form of the protein, and with other possible mechanisms of SAA binding to lipids, has not been established. Here, we have used multiple biophysical techniques, including SAXS, TEM, SEC‐MALS, native gel electrophoresis, glutaraldehyde crosslinking, and trypsin digestion to characterize the lipid‐free and lipid‐bound forms of SAA. The SAXS and TEM data show the presence of soluble octamers of SAA with structural similarity to the ring‐like structures reported for lipid‐free ApoA‐I. These SAA octamers represent a previously uncharacterized structure for lipid‐free SAA and are capable of scaffolding lipid nanodiscs with similar morphology to those formed by ApoA‐I. The SAA–lipid nanodiscs contain four SAA molecules and have similar exterior dimensions as the lipid‐free SAA octamer, suggesting that relatively few conformational rearrangements may be required to allow SAA interactions with lipid‐containing particles such as HDL. This study suggests a new model for SAA–lipid interactions and provides new insight into how SAA might stabilize protein‐lipid nanodiscs or even replace ApoA‐I as a scaffold for HDL particles during inflammation.
House prices and fertility: Can the Dutch housing crisis explain the post‐2010 fertility decline?
Authors: van Wijk Daniël 
Published: April 2024

AbstractFertility has declined in many rich societies after 2010. However, the factors that explain this fertility decline remain poorly understood. In particular, little is known about how changes on the housing market contributed to the fertility decline. This study examines the links between house prices and fertility in the Netherlands, a country where house prices have risen dramatically in the past decade. Regional (NUTS 3) data for the period 1995–2022 are analysed using within‐between models. The results for the within‐effect of house prices show that after 2010, fertility decreased (more) in regions where house prices increased (more), suggesting that the housing crisis in the Netherlands can explain a substantial part of the post‐2010 fertility decline. Before 2010, however, increases in regional house prices were associated with small increases in fertility, showing that the direction of the within‐effect of house prices depends on the time period that is studied. Finally, differences in house prices between regions are not consistently associated with fertility.
Serious neurological adverse events in immunocompetent children and adolescents caused by viral reactivation in the years following varicella vaccination

Published: April 2024

AbstractSerious adverse events following vaccination include medical complications that require hospitalisation. The live varicella vaccine that was approved by the Food and Drug Administration in the United States in 1995 has an excellent safety record. Since the vaccine is a live virus, adverse events are more common in immunocompromised children who are vaccinated inadvertently. This review includes only serious adverse events in children considered to be immunocompetent. The serious adverse event called varicella vaccine meningitis was first reported in a hospitalised immunocompetent child in 2008. When we carried out a literature search, we found 15 cases of immunocompetent children and adolescents with varicella vaccine meningitis; the median age was 11 years. Eight of the children had received two varicella vaccinations. Most of the children also had a concomitant herpes zoster rash, although three did not. The children lived in the United States, Greece, Germany, Switzerland, and Japan. During our literature search, we found five additional cases of serious neurological events in immunocompetent children; these included 4 cases of progressive herpes zoster and one case of acute retinitis. Pulses of enteral corticosteroids as well as a lack of herpes simplex virus antibody may be risk factors for reactivation in immunocompetent children. All 20 children with adverse events were treated with acyclovir and recovered; 19 were hospitalised and one child was managed as an outpatient. Even though the number of neurological adverse events remains exceedingly low following varicella vaccination, we recommend documentation of those caused by the vaccine virus.

Published: April 2024

AbstractThis work introduces an innovative robust partial state feedback controller designed for robotic manipulators actuated by brushless DC motors. The proposed controller/observer structure relies solely on actuator current and robot joint position measurements, while effectively compensating for dynamic uncertainties in both the electrical (actuator dynamics) and mechanical (robot's dynamical terms) subsystems. Specifically, a model–based robust observer, eliminating the need of joint velocity measurements, is combined with a backstepping‐type controller design. As opposed to the previous model based observers that depend on the actual model parameters, the proposed observer structure utilizes the best guest estimates of the system parameters supported with a robust compensation term. This approach eliminates the need for precise knowledge of system parameters of the observer design which is a significant improvement over most of the previous results. This approach ensures the semi‐global, uniformly ultimately bounded joint tracking error signal. The overall stability of the closed‐loop system is affirmed through Lyapunov‐based arguments. Experimental studies conducted on an in‐house‐built two‐link robotic manipulator, actuated by brushless DC motors, are presented to demonstrate the effectiveness and feasibility of the proposed method.
Long‐term continuous maize: Impacts on the soil microbiome and implications for residue management

Published: April 2024

AbstractContinuous maize (Zea mays L.) (CM) cropping has been proposed to increase soil organic carbon stocks through greater residue return to soils. These residues, however, can contribute to a yield decrease known as the continuous maize yield penalty (CMYP). The objectives of this research were to (1) evaluate the efficacy of residue management practices to mitigate the CMYP when compared to a maize–soybean [Glycine max (L.) Merr.] (MS) rotation and (2) determine effects of long‐term rotation or residue sizing on soil microbial communities and carbon‐cycling enzyme activities. Two long‐term sites (17 and 19 years) with replicated blocks of CM and MS rotation were used. The yield response to management was similar at both sites, with an average CMYP of 2570 kg ha−1 with no residue management, while chopping the residue along with broadcast ammonium sulfate (AMS) reduced the CMYP by 728 kg ha−1 (28.3%). The CMYP was further reduced when a microbial blend was applied with AMS to the sized residues, reducing the CMYP by a total of 1303 kg ha−1 (50.7%). Soil bacterial communities differed by site but were unchanged by crop rotation or residue sizing. Soil fungal assemblage, particularly arbuscular mycorrhizal fungi, was influenced by rotation and site. Sizing of residues resulted in higher soil cellobiohydrolase activity for CM, but not for MS. These findings indicate that the CMYP was not directly associated with the soil bacterial community, and that management to mitigate the CMYP may be aided by elevated levels of fungal diversity under CM.

Published: April 2024

AbstractAtomically dispersed Co‐N4‐based catalysts have been recently emerging as one of the most promising candidates for facilitating CO2 reduction reaction (CO2RR). The local electronic environment of Co‐N4 sites in these catalysts is considered to play a critical role in adjusting the catalytic performance, the effort of which however is not yet clearly verified. Herein, a series of cobalt phthalocyanines with different peripheral substituents including unsubstituted phthalocyanine Co(II) (CoPc), 2,9,16,23‐tetramethoxyphthalocyaninato Co(II) (CoPc‐4OCH3), and 2,9,16,23‐tetranitrophthalocyaninato Co(II) (CoPc‐4NO2) are supported onto the surface of the multi‐walled carbon nanotubes (CNTs), affording CoPc@CNTs, CoPc‐4OCH3@CNTs, and CoPc‐4NO2@CNTs. X‐ray photoelectron spectroscopy and X‐ray absorption near‐edge structure measurements disclose the influence of the peripheral substituents on the local electronic structure of Co atoms in these three catalysts. Electrochemical tests indicate the higher CO2RR performance of CoPc‐4OCH3@CNTs compared to CoPc@CNTs and CoPc‐4NO2@CNTs as exemplified by the higher Faraday efficiency of CO, larger part current densities, and better stability displayed by CoPc‐4OCH3@CNTs at the applied voltage range from −0.6 to −1.0 V versus RHE in both H‐cell and flow cell. These results highlight the effect of the electron‐donating ‐OCH3 substituent on the enhanced catalytic activity of CoPc‐4OCH3@CNTs, which will help develop Co‐N4‐based catalysts with promising catalytic performance toward CO2RR.

Published: April 2024

AbstractThe leverage of satellite resources to establish a communication network offers a wide range of benefits, including the capability to support news gathering, broadcasting, and aeronautical and maritime tracking. The unique aspects of the satellite‐linked terrestrial network provide high‐speed services, dependable and consistent network quality, and comprehensive geographic coverage of remote regions. Unfortunately, these structural features also render the network vulnerable to unauthorized intrusion, potentially leading to significant disruptions. Consequently, the implementation of authentication measures presents an appealing solution for enhancing the overall service quality of this network. Recently, Kumar et al. presented an authentication and key agreement scheme for satellite communications. Strikingly, their scheme proves inadequate in safeguarding against several malicious attacks and reveals certain design weaknesses. In this article, we present a reliable and secure authentication protocol that takes advantage of the complexities inherent in the elliptic curve discrete logarithm problem. We assess the protocol's effectiveness against various types of attacks using formal proof, Burrows–Abadi–Needham logic, informal descriptive proof analysis, and the verification tool SCYTHER. Furthermore, we compare the computational, communication, and storage overhead of our proposed protocol to an existing one, demonstrating its efficiency and superiority.

Published: April 2024

AbstractLung cancer is a common malignancy characterized by ferroptosis, an iron‐dependent form of cell death caused by excessive lipid peroxidation. The disruption of the ubiquitination system plays a crucial role in tumor development and spread. In recent years, there has been increasing interest in utilizing ferroptosis for lung cancer treatment; however, the precise mechanism of how ubiquitination modulates ferroptosis remains unclear. We used databases to analyze STUB1 expression patterns in lung cancer tissues compared to normal tissues and performed immunohistochemistry. The functional role of STUB1 was investigated through gain‐of‐function and loss‐of‐function experiments both in vitro and in vivo. Malondialdehyde levels, Fe2+ content, and cell viability assays were employed to evaluate ferroptosis status. Downstream targets of STUB1 were identified through screening and validated using immunoprecipitation and ubiquitination assays. Our findings demonstrate that STUB1 is downregulated in lung cancer cells and functions as an inhibitor of their growth and metastasis both in vitro and in vivo while promoting ferroptosis. Mechanistically, STUB1 induces ferroptosis through E3 ligase‐dependent degradation of the ferroptosis suppressor HSPB1. Furthermore, our study elucidated the specific types and sites of modification on HSPB1 mediated by STUB1. This research establishes STUB1 as a tumor suppressor influencing proliferation of lung cancer cells as well as the epithelial‐mesenchymal transition process associated with it. Importantly, our work highlights the role of STUB1 in ubiquitination‐mediated degradation of HSPB1, providing insights for potential treatments for lung cancer.

AbstractNano‐sized polymer systems are often used as carriers for drugs and contrast agents to increase circulation time and solubility and to reduce possible side effects. These nanomedicines usually accumulate in tumor tissue due to the enhanced permeability and retention (EPR) effect. However, a targeting group may be attached to the polymer carrier in addition to the active substance to further increase tumor accumulation and specificity. In this study, the oligopeptide sequence RGD was chosen to target αvβ3 integrins overexpressed in the tumor vasculature and on some tumor cells. A set of polymer conjugates bearing a fluorescent dye and RGD peptide of different structures (linear, cyclic, branched) was prepared for use in tumor diagnosis, with a potential future application in navigated surgery. The accumulation of the most promising candidate, a targeted fluorescent nanoprobe, increased by 35% in glioblastoma tumors compared to the non‐targeted control, which accumulated only due to the EPR effect. However, the administration of a polymer‐bound modified cilengitide as an antiangiogenic treatment did not show a beneficial effect in the suppression of angiogenesis.
