Ferrimagnetic materials driven by spin-orbit torque (SOT) exhibit a distinctive characteristic of multistate magnetization switching and enable versatile applications. However, the underlying mechanism governing multistate magnetization switching in ferrimagnetic materials remains unelucidated. Here, by studying SOT-induced magnetization switching in Co/Gd ferrimagnetic multilayers with perpendicular magnetic anisotropy (PMA), we demonstrate that the multistate magnetization switching behavior is observed not only in [Co/Gd] but also in [Co/Gd]/CoFeB stacks and size-shrinking dot devices.

A new venture idea is the prerequisite for discovering or building an entrepreneurial opportunity and also the foundation for undergraduates to start a new venture. Based on social cognitive theory, this paper explores the roles of entrepreneurial education, proactive personality, and creative self-efficacy in the formation of undergraduates' new venture ideas. Using a sample of 650 undergraduates in China, we find that entrepreneurial education and proactive personality are both positively related to new venture idea formation, and proactive personalities also moderate the relationship between entrepreneurial education and new venture ideas.

Maintaining human body temperature in both high and low-temperature environments is fundamental to human survival, necessitating high-performance thermal insulation materials to prevent heat exchange with the external environment. Currently, most fibrous thermal insulation materials are characterized by large weight, suboptimal thermal insulation, and inferior mechanical and waterproof performance, thereby limiting their effectiveness in providing thermal protection for the human body. In this study, lightweight, waterproof, mechanically robust, and thermal insulating polyamide-imide (PAI) grooved micro/nanofibrous aerogels were efficiently and directly assembled by electrospinning.

Infections of multidrug-resistant pathogens including Pseudomonas aeruginosa, cause a high risk of mortality in immunocompromised patients and underscore the need for novel natural antibacterial drugs. In this study, common phytochemicals prevalent in fruits and vegetables have been demonstrated for their ability to inhibit quorum sensing (QS) in Pseudomonas aeruginosa PAO1 (PA). Ten compounds were screened virtually by molecular docking, among which, daidzein dimethyl ether originally from Albizzia lebbeck showed the most significant inhibitory effect on the formation of biofilm and the accumulation of virulence factors, including elastase, pyocyanin and rhamnolipid in PA.

Background: The Ki-67 expression level, which represents the proliferation status of cells, serves as a prognostic marker for hepatocellular carcinoma (HCC); however, the immunochemistry method currently used to evaluate Ki-67 is invasive and is not suitable for patients who have lost the chance for surgery, such as those with advanced tumors or those with other serious organic diseases. This study aimed to investigate the value of quantitative dual-energy computed tomography (DECT) parameters in predicting the expression level of Ki-67 in HCC.

Methods: This study analyzed the data of 123 consecutive patients with HCC who underwent both Ki-67 immunohistochemistry analysis and two-phase contrast-enhanced DECT imaging.

Article Synopsis
  • Engineering the microenvironment around single atom sites (SA) provides a chance to enhance their catalytic effectiveness, specifically through the design of cobalt SA with modified coordination shells.
  • The cobalt atom's first shell is altered by creating a vacancy (Co-N-V configuration), while phosphorus doping in the second shell helps regulate the local environment, leading to improved charge density and catalytic activity.
  • The innovative carbon substrate (BCF) supports fast kinetics and ensures the Co-N-V/P@BCF catalyst's robust performance in Zn-air batteries, offering enhanced reliability and application potential.

Phosphatidyl ethanolamine-binding protein (PEBP) plays important roles in plant growth and development. However, few studies have investigated the PEBP gene family in pecan (Carya illinoinensis), particularly the function of the PEBP-like subfamily. In this study, we identified 12 PEBP genes from the pecan genome and classified them into four subfamilies: MFT-like, FT-like, TFL1-like and PEBP-like.

Background: Fetal structural anomalies are detected by ultrasound in approximately 3 % of pregnancies. Numerous genetic diagnostic strategies have been widely applied to identify the genetic causes of prenatal abnormalities. We aimed to assess the value of simultaneous copy number variation sequencing (CNV-seq) and whole exome sequencing (WES) in diagnosing fetuses with structural anomalies.

The phase-sensitive optical time domain reflectometry scheme has attracted great research interest in distributed acoustic sensing (DAS) but suffers from a trade-off between the dynamic range and signal frequency. In this paper, an optical path difference (OPD) demodulation method is applied to an interferometer array composed of an ultra-weak fiber Bragg grating (UWFBG) array and an imbalanced Michelson interferometer to solve this problem. As far as we know, this is the first time that OPD demodulation has been applied to DAS.
