Anti-Interference All-Optical Logic Computing Based on a 2D Polarization-Sensitive Photodiode.

Optical logic operation is promising for ultrafast information processing and optical computing due to the high computation speed and low power consumption. However, conventional optical logic devices require either a complex structure and circuit design or a constant voltage supply, which impedes the development of high-density integrated circuits. Here, all-optical logic devices are designed using a self-powered polarization-sensitive photodiode of the GeSe homojunction, which is attributed to an anisotropic band structure and built-in electric field.

Room temperature phosphorescent wood hydrogel.

Room temperature phosphorescent (RTP) hydrogels exhibit great potential but show poor mechanical performance (Tensile strengthen <1 MPa) and non-tunable RTP performance, hindering their practical applications. Here, we develop wood hydrogel (W-hydrogel) by the in situ polymerization of acrylamide in the presence of delignified wood. As a result of the molecular interactions between the components of delignified wood and polyacrylamide, the W-hydrogel exhibit a tensile strengthen of 38.

Proteomic analysis of mouse liver lesions at all three stages of Echinococcus granulosus infection.

Echinococcus granulosus, a zoonotic parasite, can severely damage host health or even lead to host death. In humans, early diagnosis of E. granulosus infection is difficult because the initial stages of the infection tend to be asymptomatic, this delays treatment and worsens prognosis in most patients.

Intelligent DNA Nanosystem for Broad-Spectrum Oncological Typing and Therapy.

The occurrence of multiple primary cancers in individual patients underscores the need for diagnostic and therapeutic techniques with augmented cancer-targeting selectivity and broad-spectrum antitumor effects. To address this, we develop a quadruple-input-triggered R-ND-ND logic gated oncological nanosystem (OAA). This system employs four cancer-related markers (EpCAM, MUC1, APE1, and miR-21) to generate three distinct fluorescence signals, enabling precise differentiation of various cancer cell lines (MCF-7, HepG2, and HeLa) from normal cells (MCF-10A).

To investigate the function of the gene in the pentostatin and vidarabine (Ara-A) biosynthetic gene cluster in NRRL 3238, PenF was recombinantly expressed and characterized. Enzymatic characterization of the enzyme demonstrated that PenF exhibited metal-dependent nucleoside 5'-monophosphatase activity, showing a substrate preference for arabinose nucleoside 5'-monophosphate over 2'-deoxyribonucleoside 5'-monophosphate and ribonucleoside 5'-monophosphate. Metal ions such as Mg and Mn significantly enhanced enzyme activity, whereas Zn, Cu, and Ca inhibited it.

School Connectedness and Academic Burnout in Middle School Students: A Multiple Serial Mediation Model.

Higher levels of school connectedness are associated with better study habits, but their relationship with academic burnout and the underlying mechanisms have not been revealed. We used a questionnaire to investigate the relationship between school connectedness and academic burnout and the mediating mechanisms of burnout in a sample of 394 Chinese middle school students, controlling for class, gender, and grade level. The results revealed that (1) school connectedness, autonomous motivation to learn, and core self-evaluations were significantly negatively related to academic burnout; and that (2) academic self-handicapping, core self-evaluations, and autonomous motivation to learn individually mediated the effects of school connectedness on academic burnout and mediated the effects of multiple factors.

Construction and Validation of Academic Support Scale in Middle School (ASSMS).

Research on social support in China has been relatively comprehensive as psychological development cannot be separated from the social environment. Family, teachers, and friends are the main sources of social support for middle school students. If we can fully utilize the academic support provided by families, teachers, and classmates in daily life, improve students' personal efficacy, stimulate their learning motivation and desire, and provide corresponding emotional, resource, behavioral, and willingness support for middle school students, it will help them better enhance their learning adaptability, increase their investment in learning, and then improve their learning consciousness, ultimately promoting the enhancement of academic achievement and the development of their abilities.
