Published: July 2023

Abstract
Background
Exploring the relationship between individual work immersion and perceived stress is critical for effective psychological interventions and human resource management for clinical nurses as well as for alleviating nursing staff shortages, especially after experiencing a major public health event. In order to further dissect the influencing factors of perceived stress among nursing staff, our study introduces the concepts of perfectionism and social connectedness, which aim to analyse the specific pathways that influence perceived stress in terms of an individual's intrinsic and external characteristics. Therefore, this study will provide relevant recommendations for the development of stress management measures for nursing staff.
Methods
This was a cross-sectional survey. 993 clinical registered nurses were included from four hospitals in Guangzhou through a convenience sampling method. Clinical nurses' work immersion, perceived stress, perfectionism, and social connectedness were investigated using questionnaires with good reliability and validity. Relationships between variables were studied by t-test, analysis of variance, Pearson's correlation analysis, latent profile analysis, and moderated mediation analysis.
Results
This study was based on latent profile analysis. The results showed that (1) general influences on nurses' perceived stress included only child, labor relationship, labor allowance, and family support; (2) nurses' work immersion's contained four subgroups: low (12.6%), medium-low (39.8%), medium-high (39.9%), and highest (7.7%); (3) perfectionism played a mediating role between the association of work immersion and perceived stress, in which negative perfectionism has a masking effect; (4) social connectedness plays a moderating role in the mediation model of perceived stress.
Conclusions
Work immersion, perfectionism, and social connectedness have an important impact on clinical nurses' perceived stress. Nursing managers or leaders should pay attention to the variability of individual work immersion status, adopt reasonable stress management strategies, accurately identify positive perfectionist groups and mobilize intergroup intimacy, and safeguard the quality of daily nursing care in order to reduce nursing turnover and alleviate the problem of staff shortage.

Abstract
With the continuous improvement of signal noise reduction performance requirements, in view of the noise existing in the electromagnetic radiation signal acquisition process, the wavelet threshold function of traditional denoising methods has problems such as non-progressiveness and discontinuity at the threshold value. In order to achieve better signal noise reduction effect, this paper proposes a collection based on improved wavelet threshold (IWT) function and improved complete ensemble empirical mode decomposition with adaptive noise (ICEEMDAN) combined denoising algorithm. Firstly, the algorithm is used to decompose the noisy signal, and calculate the intrinsic mode function (IMF) and correlation coefficient of each order to distinguish the noise from the correlated signal. Then, the IMF component dominated by the signal is reconstructed to complete the denoising. Simulations and experiments show that the algorithm can effectively remove the noise in the charge sensing signal, and its signal-to-noise ratio (SNR) is improved by 2.4062 compared with six similar algorithms such as the improved threshold function, CEEMD algorithm, and the root mean square error (RMSE) is reduced by 0.0866, and its noise-to-noise ratio(Rnn) is reduced by 3.103 compared with four algorithms such as the improved threshold function, the improved threshold function combined with the ensemble empirical mode decomposition (EEMD), and has a good noise reduction performance, and the research results provide a new method for capturing real signals. Decomposition (EEMD) combined with denoising and other four algorithms is reduced by 3.103, which has better noise reduction performance. The research results provide a new method for collecting real signals, This indicates the feasibility of the joint denoising algorithm.

Abstract

The effect of microwave (MW) radiations on wool and silk dyeing with extract of Arjun bark (Terminalia Arjuna) powder has been investigated. The wool and, silk & dye powder were irradiated to MW treatment for up to 5 minutes. Dyeing was performed using un-irradiated and irradiated wool and silk with irradiated and un-irradiated dye powder extracts. SEM and FTIR analyses were performed to observe morphological and chemical changes in the fabric's surface before and after irradiation. Different dyeing parameters have been optimized using a central composite design through response surface methodology. Pre- and post-mordanting was done using 0.5-2.5g/100mL of sustainable chemicals and mordants. All dyed fabrics were subjected to color analysis using a Spectra Flash spectrophotometer (SF600). ISO standard methods were employed for colorfastness to light, washing, and rubbing. It has been found that 45mL of acidic extract of 3pH when employed at 75°C for 45 min after microwave treatment up to 2 min., the dyed silk fabric has furnished high yield after finishing. For wool, 35mL of methanolic extract of 5pH when employed at 45°C for 55 min after MW treatment up to 1 min. The dyed wool fabric has furnished a high yield after finishing. Before and after the dyeing of silk and wool, the Selected chemical and bio-mordants have developed colorfast shades.

Abstract
In this paper, the Bernoulli sub-equation function method is used to construct new exact travelling wave solutions of two important physical models, (2+1)-dimensional hyperbolic non-linear Schrödinger (HNLS) equation and (2+1)-dimensional Heisenberg ferromagnetic spin chain (HFSC) equation. These solutions helpful to see the behavior of the physical phenomena of these models and they are expressible in exponential functions and tanh functions. The infinitesimal generators and the symmetry group have been investigated using the Lie symmetry method. In addition, by using multiplier approaches, the conservation laws are constructed for these models. Graphical simulation of some solutions in the form of two-dimensional and three-dimensional are plotted.

Published: July 2023

Abstract
Aluminum 7075-T6 alloy has been widely employed in aviation, transport, and automobile applications due to its remarkable properties, while a lot of residual stresses can be generated in the machined surface and subsurface during the machining process. The machining parameters have significant effects on the formation of residual stress, it’s important to predict the residual stress distribution with the cutting parameters and optimize the machining parameters to acquire the desirable residual profiles. Although many efforts of current studies have been paid to the prediction of residual stress profiles in different materials and machining processes, however, few works focused on residual stress in-depth profiles in the machining of 7075-T6 aluminum alloy, and the optimization of cutting parameters for required residual stress profile has also rarely been reported as well. Therefore, this study proposed an integrated prediction model, which combines exponential decay cosine function (EDC), particle swarm optimization (PSO), and back propagation neural network (BP), to predict the in-depth residual stress profile of the machined surface in milling of 7075-T6 aluminum alloy. Furthermore, according to the predicted residual stress profile, the key features for describing the residual stress profile include the surface residual stress (SRS), maximum compressive residual stress (MCRS), depth of maximum compressive residual stress (DMCS), and depth of residual stress (DRS), were identified and analyzed. And a multiple objectives optimization was conducted based on the predicted residual stress profile features, where Kriging-based models were employed to establish the relationships between machining parameters and each objective (SRS, MCRS, and MRR i.e. material removal rate). Finally, a two-stage optimization strategy integrating NSGA-III, MOPSO, and TOPSIS algorithms, was used to address the multi-objective optimization model to obtain the expected residual stress profile and MRR. This work can provide some practical guidance for industrial production in machining 7075-T6 aluminum alloy.

Abstract
Oligonychus afrasiaticus (McGregor) (Acari: Tetranychidae) is a major pest causing substantial economic losses to date palm fruit in southern Tunisia and Algeria, where climatic conditions are very favorable to its development. As part of a study into sustainable management strategies for O. afrasiaticus, two essential oils extracted from Lantana Camara and Ruta chalepensis were tested as adulticides against female O. afrasiaticus mites. For this purpose, an analysis of the chemical composition of these two oils was carried out using the GC-MS method in conjunction with laboratory experiments against fertilised O. afrasiaticus females. The EO of L. camara was mainly composed of caryophyllene (24.33%), Humulene (26.65%) and Muurolene (14.22%). The EO of R. chalepensis was mainly composed of 2-Undecanone (50.52%), 2-Nonanone (11.27%) and 2-Octanol, acetate (9.17%). The acaricidal activity of the EOs against O. afrasiaticus was assessed by contact with females. The LC 50 after 72 h of treatment was 3.198 µL/mL and 8.312 µL/mL for L. Camara and R. chalepensis, respectively. According to the LT 50, the acute toxicity of the EOs to O. afrasiaticus, from high to low, was the Essential Oils L. camara and R. chalepensis at the concentration of 200 µl/ml. In conclusion, the Essential Oils of L. Camara and R. chalepensis have a better acaricidal effect and a high application value for the biological control of O. afrasiaticus, which provides a basis for the development of botanical acaricides.
Estimating the Expected Time to Enter and Leave a Common Target Area in Robotic Swarms
Authors: Passos Yuri Tavares , Marcolino Leandro Soriano 
Published: July 2023

Abstract
Coordination algorithms are required to minimise congestion when every robot in a robotic swarm has a common target area to visit. Some of these algorithms use artificial potential fields to enable path planning to become distributed and local. An efficiency measure for comparing them is the time to complete a task in relation to the number of individuals in the swarm. In order to compare distinct solutions as the swarm grows, experiments with different numbers of robots must be simulated to form a plot of the function of the task completion time versus the number of robots or other parameters. Nevertheless, plotting it for many robots through simulation is time-consuming. Additionally, the inference of a global swarm behaviour as the task completion time from the local individual robot motion controller based on potential fields and other dynamical variables is intractable and requires experimental analysis. Based on that, we present equations for estimating the expected task completion time of state-of-the-art algorithms, robots using only attractive and repulsive force fields and mixed teams for the common target area problem in robotic swarms with not only the number of robots as input but also environment- and algorithm-related global variables, such as the size of the common target area and the working area, average speed and average distance between the robots. This paper is a fundamental first step to start a discussion on how better approximations can be achieved and which mathematical theories about local-to-global analysis are better suited to this problem.
Microplastics in the Atmosphere: A Global Perspective

Published: July 2023

Abstract
Microplastic particles have been detected in various parts of the atmosphere. Earlier studies have attributed their primary source to the oceans. However, recent laboratory studies suggest that ocean emission fluxes are considerably lower than previously assumed, and specifically that they are lower than the sources related to transportation on land. Here, we perform model simulations of the atmospheric transport and deposition of microplastic particles at the global scale based on bottom-up reduced ocean emissions. We conclude that approximately 124 kilotons of microplastics are suspended in the atmosphere globally, and that 19 million tons/year are deposited on the Earth's surface with only 3 million tons/year being deposited to the oceans. The highest human exposure risk to microplastics is found in densely populated regions. The Arctic and Antarctica are significant receptor regions for microplastic particles with a diameter smaller than 1.5 µm that are transported over long distances.

Abstract

Background:Fibroblast activation protein-α (FAPα) is a marker of activated fibroblasts that can be selectively targeted by an inhibitor (FAPI) and visualised by PET/CT imaging. We evaluated whether the measurement of FAPα in bronchoalveolar lavage fluids (BALF) and the uptake of FAPI by PET/CT could be used as biomarkers of fibrogenesis.Methods:The dynamics of lung uptake of18F-labeled FAPI ([18F]FAPI-74) was assessed in the bleomycin mouse model at various time points and using different concentrations of bleomycin by PET/CT. FAPα was measured in BALFs from these bleomycin-treated and control mice. FAPα levels were also assessed in BALFs from controls and patients with idiopathic pulmonary fibrosis (IPF).Results:Bleomycin-treated mice presented a significantly higher uptake of [18F]FAPI-74 during lung fibrinogenesis (days 10 and 16 after instillation) compared to control mice. No significant difference was observed at initial inflammatory phase (3 days) and when fibrosis was already established (28 days). [18F]FAPI-74 tracer was unable to show a dose-response to bleomycin treatment. On the other hand, BALF FAPα levels were steeply higher in bleomycin-treated mice at day 10 and a significant dose-response effect was observed. Moreover, FAPa levels were strongly correlated with lung fibrosis as measured by the modified Aschroft histological analysis, hydroxyproline and the percentage of weight loss. Importantly, higher levels of FAPα were observed in IPF patients where the disease was progressing as compared to stable patients and controls. Moreover, patients with FAPα BALF levels higher than 192.5 pg/mL presented a higher risk of progression, transplantation or death compared to patients with lower levels.Conclusions:Our preclinical data highlight a specific increase of [18F]FAPI-74 lung uptake during the fibrotic phase of the bleomycin murine model. The measurement of FAPα in BALF appears to be a promising marker of the fibrotic activity in preclinical models of lung fibrosis and in IPF patients. Further studies are required to confirm the role of FAP in BALF as biomarker of IPF activity and assess the relationship between FAPα levels in BALF and [18F]FAPI-74 uptake on PET/CT in patients with fibrotic lung disease.

Abstract
This study evaluated the effects of dietary supplementation with citral on growth performance and intestinal parameters, and specific activity of the digestive enzymes of the Brazilian sardine Sardinella brasiliensis. The experiment was structured with two hundred and forty juvenile S. brasiliensis that were randomly distributed in a recirculating aquaculture system (RAS) composed of 12 circular tanks of 150 L (n = 20 per tank). A diet without citral addition (control) and three diets containing different levels of citral inclusion (0.5, 1.0 and 2.0 mL kg feed–1) were used in the fish feeding management during 20 days. After the period of dietary supplementation, the growth performance indexes of the fish were verified. Portions of the stomach and midgut were collected for analysis of digestive enzymes, as well as portions of the midgut for histological analysis. A significant positive relationship was found between citral supplementation and fish survival. In the specific activity of digestive enzymes, dietary citral supplementation at 2.0 mL kg feed–1 increased lipase and amylase activity. Citral supplementation positively influenced the number of villi and intestinal crypt depth. Furthermore, the inclusion of citral at 0.5 mL kg feed–1 increased the intestine diameter of the fish. However, the specific growth rate, weight gain and feed conversion were impaired with inclusions of citral at 0.5 and 1.0 mL kg feed–1. The results of the experiment suggest that the addition of citral as an additive in the diet of S. brasiliensis improved the survival of fish reared in RAS.

Abstract
Chemotherapy can cause severe pain for patients, but there are currently no satisfactory methods of pain relief. Enhancing the efficacy of chemotherapy to reduce the side effects of high-dose chemotherapeutic drugs remains a major challenge. Moreover, the treatment of chemotherapy-induced peripheral neuropathic pain (CIPNP) is separate from chemotherapy in the clinical setting, causing inconvenience to cancer patients. In view of the many obstacles mentioned above, we developed a strategy to incorporate local anesthetic (LA) into a cisplatin-loaded PF127 hydrogel for painless potentiated chemotherapy. We found that multiple administrations of cisplatin-loaded PF127 hydrogels (PFC) evoked severe CIPNP, which correlated with increased pEKR-positive neurons in the dorsal root ganglion (DRG). However, incorporating ropivacaine into the PFC relieved PFC-induced CIPNP for more than ten hours and decreased the number of pEKR-positive neurons in the DRG. Moreover, incorporating ropivacaine into the PFC for chemotherapy is found to upregulate major histocompatibility complex class I (MHC-I) expression in tumor cells and promote the infiltration of cytotoxic T lymphocytes (CD8+ T cells) in tumors, thereby potentiating chemotherapy efficacy. This study proposes that LA can be used as an immunemodulator to enhance the effectiveness of chemotherapy, providing new ideas for painless cancer treatment.

Abstract
Immune checkpoint inhibitors (ICI) invigorate immune cell functions and are effective against many cancer types. However, the potential of ICI may be limited in situations where immune cell fitness is impaired. Here, we show that the efficacy of αPD-L1-based cancer immunotherapies is compromised by the accumulation of senescent cells in mice previously exposed to sublethal irradiation or injected with doxorubicin. Similarly, we observed that the efficacy of the combination of a αCTLA-4 antibody with radiotherapy is diminished in previously irradiated mice. In both models, resistance to immunotherapy was associated with a decrease in the accumulation and activation of CD8 T cells within tumors. Elimination of senescent cells by the injection of the senolytic drug ABT263, weeks before treatments, restored immune homeostasis within the tumor micro-environment (TME) and increased mice survival in both models. Using single-cell transcriptomic analysis, we observed that the injection of ABT263 reverses the exacerbated immunosuppressive profile of myeloid cells in the TME of previously irradiated mice. These myeloid cells, when purified from established tumors, were responsible for impaired CD8 T cell proliferation in vitro. Our study shows that cancer therapies, by inducing senescence, favor the formation of an immunosuppressive TME, which can alter the efficacy of ICI. The use of senolytic drugs before ICI may constitute an interesting pharmacological approach to improve the effectiveness of cancer immunotherapies.
