This paper examines three key factors that influence investor expectations: company announcements, market seasonality and environment, and social and corporate governance (ESG). It shows that these factors individually and jointly have a significant impact on investor behavior and market dynamics. Corporate announcements serve as an important source of information that directly influences investor behavior and expectations, while market seasonality demonstrates cyclical patterns in investor expectations. Meanwhile, ESG investments reflect investors’ concerns about corporate performance in environmental protection, social responsibility, and governance. While research on these factors has been more extensive, further research is needed to combine these factors with other market dynamics and to quantify their impact on long-term investment decisions and market trends. This study aims to provide a comprehensive understanding of the diverse factors that influence investor expectations by analyzing these factors in an integrated manner. This not only provides insights for investors and market analysts, but also provides important information for policymakers in guiding the market and formulating policies.

Typical weak signal search experiments rely on resonant effects, where the resonance frequency is scanned over a broad range, resulting in significant time consumption. In this study, we demonstrate an accelerated strategy that surpasses the typical resonance-bandwidth limited scan step without compromising sensitivity. We apply this method to an alkali-noble-gas spin system, achieving an approximately 30-fold increase in scanning step size. Additionally, we obtain an ultrahigh sensitivity of 1.29 fT ⋅ Hz−1/2 at around 5 Hz, corresponding to an energy resolution of approximately 1.8 × 10−23eV ⋅ Hz−1/2, which is among the highest quantum energy resolutions reported. Furthermore, we use this sensor to search for axion-like particles, setting stringent constraints on axion-like particles (ALPs) in the 4.5–15.5 Hz Compton-frequency range coupling to neutrons and protons, improving on previous limits by several-fold. This accelerated strategy has potential applications in other resonant search experiments. Weak signal detection, as in the case for the search of Dark Matter, relies on the resonant effect, when many frequencies are scanner in search of the signal, but this is very time consuming. The authors present a magnetometry method that combines high sensitivity and a wider parameter space coverage adopting an artificially enlarged resonance width, increasing the scanning efficiency.

To facilitate the on‐demand release of hydrophilic antibiotics for accelerated repair of infected wounds, a self‐powered wound dressing incorporating a "Lock‐ON/OFF" electric field (EF)‐driven drug release mechanism combined with electrical stimulation (ES) therapy is presented. When subjected to mechanical stress, the drug exhibits controlled, slow‐release behavior, achieving a remarkable cumulative release rate of 88.57%—89 times higher than the non‐mechanical stress group. Conversely, in the absence of mechanical stress, the drug remains unreleased, maintaining a 0% cumulative release rate in a fully closed state. The dressing utilizes its piezoelectric effect to establish an electric field, enabling precise control of hydrophilic drug release by regulating the electrostatic balance between the drug carrier and the drug. Moreover, the piezoelectric field acts as an exogenous electric field, remodeling the endogenous electric field of the wound, and accelerating wound closure. Combining EF‐driven drug release with ES result in a 1.26 fold improvement in wound healing compared to ES alone. This study addresses precision therapy limitations in fully automated diagnosis and treatment, paving the way for advancements in remote diagnosis, wireless therapy, and on‐demand precision medicine.

The increasing use of fluoroquinolone antibiotics, which are found in various environmental media, is a constant threat to ecological safety and human health. In this paper, SrFeO3@MoS2 heterogeneous catalyst was prepared to activate peroxymonosulfate (PMS) for the degradation of levofloxacin (LVO). The characteristics of SrFeO3@MoS2 samples were studied and the optimum conditions for the removal of LVO by SrFeO3@MoS2/PMS system were investigated. The removal of LVO by the SrFeO3@MoS2-0.3/PMS system could reach 96.06% within 20 min of reaction. The effect of inorganic anions (SO42−, Cl−, NO3− and H2PO4−) commonly found in actual water bodies on catalytic reaction was explored. The reusability investigation revealed that the catalyst could still remove 88.06% of LVO within 20 min after four cycles. Moreover, SO4•−, •OH and 1O2 were identified by Electron Paramagnetic Resonance (EPR) tests and scavenger experiments, where the SO4•− and •OH were dominant reactive species. Combining with the XPS characterisation, the activation mechanism of SrFeO3@MoS2-0.3/PMS was proposed, and the oxygen vacancies and transition metals on the sample surface were active sites of PMS activation. Furthermore, the possible degradation pathways of LVO were well-established based on the detected intermediates. [ABSTRACT FROM AUTHOR]

Conductive polyacrylic acid/polyaniline/SiO2 (PAA/PANI/SiO2) nanocomposite hydrogels as electrolytes for a high‐performance flexible supercapacitor were prepared by combining in situ radical polymerization of anionic monomer acrylic acid, in situ sol–gel reaction of vinyltriethoxysilane (VTES), and oxidative polymerization of conductive monomer aniline (ANI). In the nanocomposite hydrogel, vinyl‐SiO2 nanoparticles served as analogous covalent crosslinkers, while the reversible noncovalent interactions (such as hydrogen bonds, electrostatic interactions, and chain entanglements) between the PAA/SiO2 and PANI networks acted as physical crosslinkers. The interconnected PANI and PAA/SiO2 networks thus constructed an interpenetrating three‐dimensional network that improved the movement of electrons and ions while also enhancing the mechanical properties of the hydrogel. At a volume ratio of ANI to VTES of 50:200, the compressive strength and conductivity of PAA/PANI/SiO2 hydrogels were as high as 1505 kPa and 4.42 S/m, respectively. Moreover, the flexible supercapacitors based on the nanocomposite hydrogel electrolyte exhibited high specific capacitance (574.7 F/g), energy density (19.6 Wh/kg), and power density (1.4 kW/kg) at a current density of 0.05 A/g. Meanwhile, these supercapacitors exhibit exceptional flexibility and mechanical stability, and can be repeatedly bent without degrading performance. This nanocomposite hydrogel has considerable potential for use in other flexible energy devices and electronics due to its excellent mechanical and electrochemical properties. Highlights: Conductive nanocomposite hydrogel have good conductivity and mechanical properties.Conductive hydrogels are used as electrolytes for flexible supercapacitors.Vinyl‐SiO2 served as analogous covalent crosslinkers for the hydrogel.Noncovalent bonds between PAA/SiO2 and PANI acted as physical crosslinkers.Interconnected PANI and PAA/SiO2 networks formed an interpenetrating network.

Phosphorus (P) availability in soil is often limited, posing a challenge for sustainable agricultural production. Phosphate solubilizing microorganisms (PSMs) have emerged as a promising biological approach to enhance soil P availability while minimize negative environmental impacts. Exploring the impact of PSMs on increasing soil available P is crucial for optimizing the utilization of insoluble P in soil and promoting sustainable agricultural practices. In this article, we provide a comprehensive review on the dynamics of soil available P, including its input, loss and transformation processes. Additionally, we draw a conclusion about how PSMs increase the availability of P in soil, including solubilizing inorganic P (Pi) and organic P (Po) by secreting substances such as protons, organic acids, inorganic acids, exopolysaccharides, hydrogen sulfide, siderophores and phosphatases. Notably, the factors influencing the P solubilizing activity of PSMs in soil are thoroughly discussed. Moreover, practical applications of PSMs for increasing soil P availability are summarized. Future research should focus on exploring novel PSM isolates, conducting long-term field experiments to assess the effects and potential risk of PSMs under diverse conditions, and investigating synergistic approaches with other P activators or beneficial microorganisms. This review will advance our understanding of PSMs and their practical application, enabling their widespread adoption in agricultural systems. [ABSTRACT FROM AUTHOR]

Unexpectedly facile dearomative intramolecular (4+3) cycloadditions of thiophenes with epoxy enolsilanes, providing sulfur‐bridged cycloadducts, are reported. A total of fifteen thiophene substrates have been found to undergo (4+3) cycloaddition smoothly to produce endo and exo (4+3) adducts in yields of up to 83 % with moderate to good diastereoselectivity. Complete conservation of enantiomeric purity was observed when the optically enriched epoxide was used. The desulfurizing transformations of the sulfur‐bridged skeleton of the cycloadducts provide functionalized 6,7‐fused bicyclic frameworks consisting of 1,3‐cycloheptadiene subunits. Density functional theory calculations reveal the origins of the facile dearomatization of thiophenes in these (4+3) cycloadditions. [ABSTRACT FROM AUTHOR]

The use of nanocatalytic particles for the removal of refractory organics from wastewater is a rapidly growing area of environmental purification. However, little has been done to investigate the effects of nanoparticles on soil-plant systems with antibiotic contamination. This work assessed the effect of molybdenum disulfide (MoS 2 ) on the soil-Phragmites communis system containing levofloxacin (LVX). The results showed that the addition of MoS 2 had restoration potential for stressed plant. The MoS 2 with catalytic activity promoted the transformation of LVX in rhizosphere soils. The transformation pathways of LVX in the different exposure groups were proposed. The continuous output of radicals in the high MoS 2 dosage group facilitated the transformation of LVX to small molecule compounds, which were eventually mineralized. Moreover, the electron-density-difference analysis revealed the easier flow of electrons from the MoS 2 surface towards the LVX molecules. This finding provides theoretical support for the application of nanocatalytic particles in ecological environments., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Triclocarban (TCC), an emerging contaminant in water environments, its effects on freshwater biofilms remain insufficiently understood. This study investigates the effects of TCC exposure (at concentrations of 10 μg L -1 and 10 mg L -1 ) on mature freshwater biofilms. TCC was found to inhibit biofilm activity as evidenced by changes in surface morphology and the ratio of live/dead cells. Moreover, both concentrations of TCC were observed to modify the structure of the biofilm community. Metabolomics analysis revealed an overlap in the toxicity mechanisms and detoxification strategies triggered by various concentrations of TCC in biofilms. However, the higher toxicity induced by 10 mg L -1 TCC resulted from the downregulation of proline betaine, disrupting the homeostasis of cellular osmotic pressure regulation in biofilms. Notably, lipid and lipid-like molecules showed high sensitivity to different concentrations of TCC, indicating their potential as biomarkers for TCC exposure. Annotation of the differential metabolites by KEGG revealed that alterations in amino acid and carbon metabolism constituted the primary response mechanisms of biofilms to TCC. Moreover, the biofilm demonstrated enhanced nucleic acid metabolism, which bolstered resistance against TCC stress and heightened tolerance. Furthermore, elevated TCC concentrations prompted more robust detoxification processes for self-defense. Overall, short-term exposure to TCC induced acute toxicity in biofilms, yet they managed to regulate their community structure and metabolic levels to uphold oxidative homeostasis and activity. This research contributes to a deeper comprehension of TCC risk assessment and policy control in aquatic environments., Competing Interests: Declaration of Competing Interest ☒ The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Gastrointestinal cancers account for approximately one-third of the total global cancer incidence and mortality with a poor prognosis. It is one of the leading causes of cancer-related deaths worldwide. Most of these diseases lack effective treatment, occurring as a result of inappropriate models to develop safe and potent therapies. As a novel preclinical model, tumor patient-derived organoids (PDOs), can be established from patients' tumor tissue and cultured in the laboratory in 3D architectures. This 3D model can not only highly simulate and preserve key biological characteristics of the source tumor tissue in vitro but also reproduce the in vivo tumor microenvironment through co-culture. Our review provided an overview of the different in vitro models in current tumor research, the derivation of cells in PDO models, and the application of PDO model technology in gastrointestinal cancers, particularly the applications in combination with CRISPR/Cas9 gene editing technology, tumor microenvironment simulation, drug screening, drug development, and personalized medicine. It also elucidates the ethical status quo of organoid research and the current challenges encountered in clinical research, and offers a forward-looking assessment of the potential paths for clinical organoid research advancement., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Yan, He, Zhu, Ye, Chen, Zhu, Zhan and Ma.)
