Abstract
To investigate the effects of biological fertilizers and phosphorus on the effects of reduced irrigation in medicinal plant lavender, a split-split plot experiment based on randomized complete block design (RCBD) with three replications was conducted during two cropping years of 2018/2019 and 2019/2020 at The Research Station, Islamic Azad University of Tabriz. The studied treatments in this research included irrigation levels (irrigation after 60, 90, and 120 mm of class A evaporation pan) as the main factor, four levels of seed inoculations (inoculation with Thiobacillus, inoculation with Pseudomonas, combined inoculation (Thiobacillus + Pseudomonas) and control (non-inoculation) as a sub-factor and the amount of phosphorus chemical fertilizer (0 and 50 kg/ha) was as a sub-sub-factor. The experiment assessed several traits, including dry weights of flowers, the quantity of cell membrane leakage, leaf relative water content, soluble sugars content, proline content, superoxide dismutase, catalase, and peroxidase activities. This two-year experiment measured the following traits: Wet weight of the flower, quantity of cell membrane leakage, leaf relative water content, proline, superoxide dismutase, catalase, and peroxidase activities. The wet weight of flowers increased compared to the control during the first year of the investigation due to all irrigation levels, phosphorus application, and inoculation with integrated biological fertilizers. Results showed that in the first year of measuring, all irrigation levels, phosphorus application, and integrated biological fertilizer inoculation increased the wet weight of the flower compared to the control. The greatest amount of proline, catalase, peroxidase, and superoxide dismutase enzymes was obtained at 60 ml of evaporation with a consumption of 50 kg of phosphorus per hectare and applying Thiobacillus + Pseudomonas. This study also showed that the interactions between irrigation levels, phosphorus fertilizer, and biological fertilizer on the characteristics of cell membrane leakage rate and leaf-relative water content were not significant. The results of the second-year experiment showed that the highest amount of catalase, superoxide dismutase, and peroxidase was obtained as a result of the irrigation combination after 120 mm of evaporation pan and the application of Thiobacillus + Pseudomonas and phosphorus fertilizers and proline content (5.48 mg/g wet weight) were determined by irrigation treatment after evaporation of 120 mm and without application of bacteria and phosphorus fertilizers. It appears that plant growth-promoting bacteria and phosphorus increased the yield of lavender flowers by reducing the negative effects of drought stress.

Abstract
Aging is associated with a decline in stem cell functionality and number across the organism. In this study, we aimed to further unravel Muscle Stem Cells (MuSCs) aging by assessing how systemic factors influence MuSC fate decisions through long-term epigenetic landscape remodelling. As aging is intricately linked to a pro-inflammatory shift, we studied the epigenetic effects of inflammatory signals in MuSCs and measured decreased H4K20me1 levels. This loss disrupts MuSC quiescence, largely through epigenetic silencing of Notch target genes. In the setting of inflammatory signals or aging, the lack of Kmt5a and the subsequent absence of de novoH4K20me1 culminate in cell death by ferroptosis. Aged MuSCs manifest abnormal iron metabolism and reduced Gpx4 levels, resulting in the accumulation of intracellular iron, increased reactive oxygen species, genomic instability, and lipid peroxidation. We showed that ferroptosis is the predominant mode of cell death in aged MuSCs, with remarkably high levels of lipid peroxidation; a phenomenon we also observed in aged hematopoietic stem cells. Implementing preventative strategies to inhibit systemic inflammation prevented aged MuSC ferroptosis, preserving their numbers and regenerative capabilities. This intervention significantly enhanced aged muscle regeneration and strength recovery and extended both lifespan and healthspan in mice. This study delineates a previously underappreciated fate trajectory for stem cell aging, and offers meaningful insights into the treatment of age-related disorders.

Abstract

In this study, we adopted tree ring climatology to understand the differences in the response of the radial growth of two typical tree species to extreme climate indices in the Greater Khingan Mountains region, Northeast China. In particular, we collected 231 samples of Dahurian larch (Larix gmelinii) and Mongolian pine (Pinus sylvestris var. mongolica) from four sampling points in the in the Genhe region of the Greater Khingan Range Mountains to establish a standardized chronology of Dahurian larch and evaluate extreme climate indices and their trends. Pearson correlation analysis was employed to analyze the growth response of Dahurian larch and Mongolian pine pine to extreme climatic factors at each sampling point, and the similarities and differences in the radial growth characteristics of each tree species and their response to climatic factors before and after a sudden change in temperature were investigated. The results revealed that after the sudden change in climate, the radial growth of larch and Mongolian pine pine exhibited the same upward trend that was more significant at high altitudes, while the radial growth of Mongolian pine pine had a more obvious upward trend at low altitudes. Correlation analysis with climate elements demonstrated that in May of the current year, the radial growth of high-elevation Dahurian larch was significantly positively correlated (p < 0.05)with the minimum temperature minima, while the radial growth of larch was significantly positively correlated with temperature, and the minimum temperature minima, maximum temperature minima and number of warm night days were significantly positively correlated with the number of cold day days. Following the sudden change in temperature, in May of that year, the radial growth of low elevation larch exhibited a significant positive correlation with temperature, a significant positive correlation with the maximum temperature minima and number of warm night days, and a significant negative correlation with the number of cold day days. Moreover, the radial growth of Mongolian pine showed a significant positive correlation with the number of warm night days and minimum temperature minima. After the abrupt climate change, the radial growth of trees in the low elevation areas of Greater Khingan Range were all inhibited by the high temperature in summer, while with the continuous increase of global temperature, the drought stress induced by the high temperature was the main factor inhibiting the growth of high-elevation larch. This study demonstrates that under global warming, the Greater Khingan Range area is becoming increasingly unsuitable for the growth of larch, the distribution area of the natural forest of Mongolian pine may expand, and the distribution area of natural larch forests may decline.

Abstract

Accurate assessment of solar cell conversion efficiency relies heavily on the precise determination of unobserved parameters within photovoltaic (PV) cell models. To address this need, we present a novel approach named MOLNMGWO in this paper. This method aims to streamline the process of identifying latent parameters in PV models. MOLNMGWO ingeniously combines the Nelder-Mead simplex method with a mutated opposition-based learning mechanism derived from the gray wolf optimizer (GWO).Gaussian-Cauchy mutation in mutated opposition-based learning mechanism provides the ability to jump out of the local optimum. The opposition-based learning ensures that the local exploitation ability of the algorithm guarantees that it always obtains a better solution. In addition, the introduced Nelder-Mead simplex method also enhances its capability for local search and convergence precision. Evaluating the efficacy of MOLNMGWO involved a comprehensive comparison with various cutting-edge algorithms using the CEC2014 function set. The findings underscore the remarkable superiority of MOLNMGWO over these diverse algorithms. Subsequently, the application of MOLNMGWO to discern enigmatic PV parameters in the context of the single-diode model (SDM), double-diode model (DDM), and three-diode model (TDM) was pursued under consistent temperature and illumination circumstances.The MOLNMGWO can identify these parameters accurately and reliably. Finally, MOLNMGWO was used to identify the three commercial PV module parameters under diverse temperature and light conditions, and satisfactory results were obtained. All the above three experimental results show that MOLNMGWO has excellent competitiveness and that MOLNMGWO can accurately and efficiently identify photovoltaic parameters even in harsh environments. Overall, the MOLNMGWO is a novel, reliable and effective method to overcome the problem of the estimation of parameters for solar cell PV models.

Published: March 2024

Abstract
This study used a hydrothermal (autoclave) method to successfully prepare iron oxide nanoparticles (Fe2O3-NPs) by combining (Fe2NO3) salt with chitosan extract. In the antibacterial process, the IO-NPs are crucial in getting rid of germs and creating a healthy environment. IO-NPs were investigated using XRD spectra ,FE-SEM, UV-visible and, PL. According to the XRD results, Fe2O3 NPs have a face center cubic (FCC) structure and a crystal size of 10 to 25 nm. The diffraction peaks for Fe2O3 NPs can be assigned with good crystal quality. Furthermore, the FE-SEM results showed that the Fe2O3-NPs had grain size of 66 to 88 nm. The energy band gap, according to UV-visible spectra, is 4.2 eV. The inhibition of zones, which were 20 to 26 mm for gram-positive bacteria (Staphylococcus aureus), was used to determine the antibacterial qualities of Fe2O3-NPs.

Abstract

White-tailed deer (Odocoileus virginianus) have emerged as a potential reservoir host for SARS-CoV-2 given their susceptibility to infection and demonstrated high rates of seroprevalence across the United States. As SARS-CoV-2 circulates within free-ranging white-tailed deer populations, there is the risk of transmission to other wildlife species and even back to the human population. The goal of this study was to determine the susceptibility, shedding, and immune response of North American elk (Cervus elaphus canadensis) to experimental infection with SARS-CoV-2, to determine if another wide-ranging cervid species could potentially serve as a reservoir host for the virus. Here we demonstrate that while North American elk do not develop clinical signs of disease, they do develop a neutralizing antibody response to infection, suggesting the virus is capable of replicating in this mammalian host. Additionally, we demonstrate SARS-CoV-2 RNA presence in the medial retropharyngeal lymph nodes of infected elk three weeks after experimental infection. Consistent with previous observations in humans, these data may highlight a mechanism of viral persistence for SARS-CoV-2 in elk.

Abstract

The distribution and diversity of insects are crucial conservation issues. The order Trichoptera comprises numerous endangered species, but the rarity of some makes it challenging to determine their conservation priority. Research in Slovakia in recent decades has focused mainly on limnological studies, resulting in more frequent data on caddisfly larvae. Our research focused mainly on adult caddisflies, resulting in more reliable and accurate identification of many species that cannot be identified in the larval stage. We combined several entomological methods, including sweeping, Malaise traps, and UV light attraction, to increase the likelihood of catching rare species. The text lists and discusses the discoveries of caddisfly species that are particularly important for faunistics or biodiversity in Slovakia, as well as in the Central European context. Enoicyla reichenbachii (Kolenati, 1848), Limnephilus incisus Curtis, 1834, Ptilocolepus granulatus (Pictet, 1834) and Oecetis testacea (Curtis, 1834) were recorded for the first time in Slovakia. The rare species Hagenella clathrata (Kolenati, 1848) and Adicella balcanica Botosaneanu and Novák, 1965, previously found in Slovakia, were also recorded. Additionally, a new locality of Adicella syriaca Ulmer, 1907 indicates a further northward shift of this Mediterranean species. We further discussed the faunistically important records of Beraeamyia hrabei Mayer, 1937, Allotrichia pallicornis (Eaton, 1873), Ceraclea riparia (Albarda, 1874), Grammotaulius nitidus (Müller, 1764) and Limnephilus fuscicornis Rambur, 1842 from Slovakia. The conservation status of each species is proposed and discussed based on our faunistic records, in accordance with the forthcoming update of the Slovak Red Book.
Stability from subspace rotations and traveling waves

Published: March 2024

Abstract

Cortical activity shows stability, including the ability to recover from disruptions. We analyzed spiking from the prefrontal cortex (PFC) of monkeys performing working memory tasks with mid-memory-delay distractions. Perturbation of cortex by events (a gaze shift or visual inputs) caused rotational dynamics in subspace that could return spiking to patterns similar to those before the perturbation. In fact, after a distraction, rotations were fuller when the task was correctly performed vs when errors were made. We found a direct correspondence between state-space rotations and traveling waves rotating across the surface of the PFC. This suggests a role for subspace rotations in cortical stability and a correspondence between subspace trajectories and traveling waves.

Published: March 2024

Abstract

Based on the research of sweep and reverse angle deformation laws of the elbow and hand wing sections during the flight of large birds, a multi-section variable-sweep wing structure adapted to large-size UAVs is proposed in this paper. The feasibility of the centroid self-trim compensation morphing process by using collaborative deformation of inner and outer sections is ex-plored. Firstly, a calculation and evaluation method of the driving moment required for morphing based on the vortex lattice method is established. Then, five preselection models with different span ratios of the inner and outer sections of the multi-section variable sweep-wing UAV are constructed. Finally, from the aspects of static stability margin, changes in aerodynamic characteristics, and performance requirements of the drivers during the collaborative morphing process, the influence of multi-parameters on the comprehensive performance of the multi-section morphing wing is analyzed, and the reasonable design range of the span ratio of the inner and outer wing sections of the research object is given. The results show that the multi-section morphing wing proposed in this paper has a significant advantage in solving the problems of drastic changes in aerodynamic, dynamic, and operational characteristics caused by large-size wing morphing. The maximum output power requirement of the drivers in the symmetrical self-trim compensation morphing process can be reduced by increasing the ratio of the inner wing section to the preselected model, and the efficiency of the driver can be improved. The preselection model of the multi-section variable swept-wing UAV with optimal driving moment performance is determined by the comprehensive analysis results, and the corresponding span ratio of the inner and outer wing sections in the morphing sections is about 64.03% and 35.97%, respectively.

Published: March 2024

Abstract

This study aimed to synthesize a high-value product, silicon carbide (SiC) whickers, using carbon black from recycled tires and waste silicon dioxide obtained from the photovoltaic industry via mechanical and thermal activation (IMTA) technology. Diverse whisker morphologies, including needle-like, nanowire-like, bamboo-like, and bead-like structures, were obtained. Furthermore, the effects of the synthesis parameters, such as the ball milling time, carbon‒silicon molar ratio, pyrolysis temperature, and pyrolysis time, on the quality of the SiC whiskers were investigated. The results showed that the carbon‒silicon ratio had the greatest impact on whisker formation, followed by the pyrolysis temperature, pyrolysis time, and ball-milling time. The purity of the synthesized silicon carbide whiskers was observed in the range of 42.63%-54.84%. Both the pyrolysis temperature and time improved the properties of the SiC. Additionally, the strength, hardness, abrasion resistance of the rubber and wear-resistant paint could be improved by adding less than 4% synthesized SiC whiskers, as confirmed via commercial product testing. The excellent performance of the synthesized SiC whiskers and the competitive market advantage of improving the product quality at a low economic cost were confirmed in this study.
Comparative Analysis of Dexmedetomidine, Midazolam, and Propofol Impact on Epilepsy- Related Mortality in the ICU: Insights from the MIMIC-IV Database
Authors: Li Xun , Yue Wei 
Published: March 2024

Abstract

Background
Dexmedetomidine (Dex), midazolam, and propofol are three distinct sedatives characterized by varying pharmacological properties. Previous literature has indicated the positive impact of each of these sedatives on ICU patients. This study aimed to assess the impact of Dex, midazolam, and propofol on the survival of PWE.
Methods
Retrospective data were obtained from the Medical Information Mart for Intensive Care (MIMIC)-IV database (version 2.0). PWE were categorized into Dex, midazolam, and propofol groups based on intravenously administered sedatives. PWE without standard drug therapy were included in the control group. Comparative analyses were performed on the data among the groups.
Results
Kaplan-Meier curves demonstrated a significant improvement in survival rates for the Dex group compared to the control group (p = 0.025). Analysis of Variance (ANOVA) revealed no significant differences in survival rates among the Dex, midazolam, and propofol groups (F = 1.949, p = 0.143). The nomogram indicated that compared to midazolam and propofol groups, Dex was more effective in improving the survival rate of PWE.
Conclusion
Dex might appear to outperform midazolam and propofol in improving the survival rate in nomogram.
