Summary: In the semiarid steppe of Erguna, Inner Mongolia, increasing nitrogen input can significantly enhance ecosystem C exchange, but only when soil moisture exceeds a certain threshold. In addition to considering the interactions of water, temperature, and nitrogen, their synergistic effects also need to be taken into account. During the growing seasons, the number of days with soil moisture content higher than 15% accounted for only about one third.

Summary: The availability of nitrogen (N) has been found to influence the mineralization of soil organic carbon (C), but its effect on the decomposition of native soil organic C induced by labile C input (i.e., priming effect) remains unclear. This study investigated the impact of N supply rates on the magnitude and direction of the priming effect, and how this interacted with soil layers differing in organic C content. The results showed that N addition increased the priming effect up to a certain level, and this effect was greater in the surface layer of topsoil compared to the subsurface layer. These findings highlight the susceptibility of soil organic C to loss through N-enhanced priming.

Summary: Land-use/land-cover change has significant impacts on ecosystem services. The Grain-for-Green Programme in China aims to improve ecosystem services. The study in the Jinghe River basin shows decreases in farmland and degraded grassland, and an increase in forestland. Water yield, sediment control, and carbon storage have improved. Grassland restoration areas have better water yield than forestland restoration areas, but the sediment export is difficult to judge. Grasses are better vegetation for the Grain-for-Green Programme in the Loess Plateau. Trade-offs between water yield and sediment control should be considered.

Summary: Soils play a crucial role in ecosystem functioning and service provisioning. Plant diversity has positive effects on soil organic matter, but most studies have focused on topsoil and long-term studies are limited. This study investigated the impacts of plant diversity on soil carbon and nitrogen concentrations and stocks, and found that higher plant diversity increased carbon and nitrogen storage, particularly in the topsoil. The effects of plant diversity on soil organic matter became stronger over time and extended to subsoil layers.

Summary: The study found that irrigation in New Zealand significantly reduced soil carbon and nitrogen stocks, with greater losses observed at greater durations of irrigation and lower aridity levels. The impact of irrigation on soil C and N was negatively related to aridity, with increasingly significant carbon losses observed at sites with higher precipitation levels. The results suggest that a new equilibrium may be reached with lower carbon stocks in irrigated grasslands compared to unirrigated grasslands.

Summary: The restoration of degraded lands and minimizing land degradation are important tasks in global environmental land management schemes. Soil organic carbon (SOC) is a key indicator of soil productivity and influences soil ecosystem services. Detecting changes in SOC stock within a short timeframe presents a challenge for land managers. This study aimed to identify early indicators of changes in SOC stock and their drivers by synthesizing global data on the impacts of land use change on SOC fractions and soil structural properties. The conversion of arable lands to forests and grasslands resulted in a significant increase in SOC fractions and soil structural stability. The study also found that certain SOC fractions, particularly particulate organic C and organic carbon stored in small macroaggregates, were strongly correlated with total SOC and can serve as suitable indicators of short-term changes in SOC stock. Further field studies are needed to validate the findings of this study and assess the applicability of SOC metrics under different land use change scenarios.

Summary: (In + Nb)-doped Cex(In0.5+Nb0.5)1-xO2 (with x = 0, 0.005, 0.05, and 0.1) ceramics were prepared using a conventional solid-state method. The dielectric properties of the ceramics were studied at temperatures ranging from 3 to 475 K and frequencies ranging from 102 to 106 Hz. All doped samples exhibited a colossal permittivity behavior, with the sample at x = 0.005 showing the best frequency stability. Two thermally activated relaxations contributed to the colossal permittivity behavior: a low-temperature polaron relaxation (R1) caused by electron hopping between Ce3+ and Ce4+ ions, and a high-temperature dipole relaxation (R2) caused by the oxygen-vacancy-dopant defect pair.

Summary: Through a literature review, it was found that nitrogen input stimulates plant primary productivity but inconsistently affects microbial activities and soil carbon sequestration. Nitrogen fixation increases and nitrogen leaching decreases under elevated CO2 and temperature or along ecosystem succession, resulting in improved soil nitrogen availability and supporting plant growth and ecosystem carbon sequestration. Ecosystem models that fail to simulate these dynamic adjustments cannot accurately predict carbon-nitrogen coupling and ecosystem carbon sequestration.

Summary: This design proposes two different load disturbance observers, the traditional Luenberger observer and novel internal model control (IMC) observer, to address the problem of load disturbance and lack of load thrust observation in permanent magnet synchronous linear motor (PMSLM) control system. The IMC observer uses proportional and integral form to observe the load disturbance, effectively improving identification convergence speed and compensation control effect. Through the comparison and verification, it is concluded that the control strategy accurately tracks the load disturbance, simplifies the system structure, and enhances the anti-disturbance capability and dynamic response capability of the PMSLM.

Summary: Anti-PD-1 therapy shows effective outcomes in both liver cancer patients and non-liver cancer patients infected with HBV. Through a retrospective multicenter study, it is found that HBV+ non-liver cancer patients have better responses to anti-PD-1 therapy compared to HBV- non-liver cancer patients. Additionally, in HBV+ ESCC patients, the cytotoxicity score of T cells and MHC score of B cells significantly increase after anti-PD-1 therapy. CX3CR1(high) T-EFF, a subset of CD8(+) T-EFF, is also associated with better clinical outcomes in HBV+ ESCC patients.

Summary: In this paper, an error modeling method is proposed to accurately evaluate and improve the accuracy of parallel manipulators based on accuracy indices. The established error models reflect the effect of motion/force transmission and constraint characteristics on error transmission. The correctness of the models is demonstrated through error modeling cases of 6-PUS and 3PRS parallel manipulators. Local and global accuracy indices are proposed based on the error model, and utilized for dimensional optimization of a 5-DoF parallel machine tool named DiaRoM, resulting in higher simulation accuracy.

Summary: Carbon-use efficiency (CUE) has been widely used as a constant value in earth system models, but its response to warming was unclear due to the lack of manipulative experiments. In a 7-year warming experiment, we found that both plant-level (CUEp) and ecosystem-level (CUEe) CUE varied significantly under warming. The effects of warming on CUEp were correlated with soil water content, while the effects on CUEe were correlated with soil temperature changes. Our findings have important implications for reducing modeling uncertainties and predicting C-climate feedbacks.

Summary: The study introduces a rigid-flexible coupling error modeling method to address the kinematic calibration hindered by gravitational deformation in large-sized seven-degrees-of-freedom hybrid spray-painting robots. The method combines the finite element method and stiffness matrix method to assess the spatial gravitational deformation and establishes a rigid-flexible coupling error identification model. By simplifying the parameters using the nonlinear least-square regularization method, an error compensation method is proposed. The kinematic calibration test results show significant reduction in position errors and improved error convergence speed, demonstrating the feasibility and effectiveness of the method. The proposed method is instrumental in accurate kinematic calibration of large-sized seven-degrees-of-freedom hybrid robots.

Summary: Unsound management practices and climate change have led to grassland degradation in Tibetan grasslands, providing habitats for rodent activities. Rodent bioturbation has depth-dependent impacts on soil organic carbon contents, with a significant decrease in topsoil and a significant increase in the deeper soil layer. Other soil layers show nonsignificant changes. These depth-dependent responses are associated with rodent tunnel burrowing, foraging, excrement deposition, and mixing of soil layers.
