Summary: The study of the C-13(alpha,n)O-16 reaction in the astrophysical s process, particularly in the energy window of the Gamow peak, is crucial but challenging due to the high uncertainties in cross section measurements. A new deep-underground measurement has significantly reduced uncertainties and provided data directly relevant to the s-process, impacting the understanding of nucleosynthesis in stellar models.

Summary: China Jinping Underground Laboratory (CJPL) is ideal for studying solar, geo-, and supernova neutrinos, and precise measurement of cosmic-ray background is crucial for neutrino experiments. A study using a 1-ton prototype detector at CJPL detected high-energy muon events, providing a convenient estimation for the muon flux of an underground experiment. The study compared muon fluxes at different laboratory locations and found that flux at locations under mountains is generally larger than at those down mine shafts.

Summary: This paper describes a system and experimental procedure using integrating passive detectors, such as TLDs, to measure ultra-low-level ambient dose equivalent rate values at the SNOLAB facility in Canada. The long exposure time of these detectors allows for better sensitivity in measuring ultra-low activity levels. The study concludes that TLDs provide reliable results in measuring the ultra-low-level environmental radiation background.

Summary: By capping the hydroxyl groups of a-cellulose through benzylation, the measurement error caused by hygroscopicity can be minimized. The O-18/O-16 ratio of a-cellulose increases with the degree of benzyl substitution. It is recommended to establish a moisture adsorption-degree of substitution equation for accurate correction of a-cellulose d(18)O measurement.

Summary: In this work, the influence of hydrogen on GS80A steel was studied through mechanical tests and fracture surface observations. The results showed a significant reduction in ductility, ultimate tensile strength, yield strength, and fatigue life due to hydrogen. For the first time, a neural network model and a typical gray theory were used to reproduce the S-N curve based on experimental fatigue life with and without the presence of hydrogen, and reasonable agreement was found between the two models. The H-affected P-S-N curves were obtained using the Bootstrap method, indicating that the fatigue life obtained under the same conditions converged to a Weibull distribution.

Summary: As a destructive plant pathogen, Phytophthora infestans secretes specific proteins called RxLR effectors that facilitate infection. One of these effectors, PiAvr3b, causes a specific immune response and also suppresses the general immune response. The molecular basis of these dual activities has been unknown, but this study found that specific amino acids in PiAvr3b were responsible for both activities. The localization of PiAv3b within the cell also plays a role in its ability to stimulate or suppress immune responses.

Summary: The recently developed defective 19-electron half-Heusler compounds with intrinsic vacancies and low lattice thermal conductivity have inferior thermoelectric performance compared to the conventional 18-electron ones. However, by achieving selective scatterings of phonons and electrons through lanthanide contraction as well as alloying with Ta, a peak zT exceeding unity is obtained in Nb0.83CoSb, enlarging the category of high-performance thermoelectric materials.

Summary: With the global prevalence of methamphetamine (METH), methamphetamine-associated cardiomyopathy (MAC) has become widespread, particularly among young people, leading to heart failure. The mechanism underlying MAC development remains unclear. In this study, an animal model exhibiting cardiac injury consistent with MAC was evaluated and found to display cardiac hypertrophy, fibrosis remodeling, and systolic dysfunction. The expression of cellular senescence markers (p16 and p21) and senescence-associated secretory phenotype (SASP) was significantly increased. Further analysis revealed that the key molecule GATA4 was upregulated in response to METH exposure. Knockdown of GATA4 expression in H9C2 cells attenuated METH-induced cardiomyocyte senescence. Therefore, METH induces cardiomyopathy through cellular senescence mediated by the GATA4/NF-kappa B/SASP axis, which presents a potential target for MAC treatment.

Summary: Hypertension associated with hyperhomocysteinemia (HHcy) is responsible for 75% of hypertension cases in China. The study aimed to investigate the molecular mechanism of HHcy-induced arterial injury in hypertension. Experimental results showed that oxidative stress and inflammation pathways are involved in the arterial injury, with inflammation playing a leading role through the Akt1/NF-kappa B p65/IL-6 signaling pathway.
