Based on a quasi-natural experiment that mandates a subset of listed firms to issue standalone corporate social responsibility(CSR)reports,we examine whether mandatory CSR disclosure improves analysts’information *** focus on two properties of analysts’earnings forecasts:forecast error and forecast *** find that the mandatory issuance of standalone CSR reports is related to less forecast error and less dispersed forecasts,and the effect varies with the firm-level information environment and provincelevel *** tests show that the improvement in forecast properties is mainly driven by CSR reports that i)are of high quality and ii)contain more long-term-oriented information than other CSR *** findings provide evidence that mandatory CSR disclosure plays an important informational role for financial analysts.

Quantum gates are crucial for quantum computation and quantum information processing. However, their effectiveness is often hindered by systematic errors and decoherence. Therefore, achieving resilient quantum gates to these factors is of great significance. We present a method to construct nonadiabatic holonomic single-and two-qubit gates in a Rydberg ground-state-blockade regime. Our approach utilizes a far-off-resonant technique for the single-qubit gate and a modified Rydberg antiblockade for the two-qubit gate. The reduction of the population of single-and two-excitation Rydberg states and the nonadiabatic holonomic process during the construction of the gates ensure robustness to decoherence and systematic errors, respectively. Numerical results demonstrate the fidelity and robustness of our scheme. The proposed scheme holds promise for future applications in quantum computation and quantum information processing tasks.

The power plant of planning construction Shawan hydropower station was planned in the toe area of the right bank *** scale cracks with maximum length over 20 m and downward displacement over 1.0 m occurred in the Quaternary accumulation of the middle part of the slope during excavating site for the power plant,and as a result the excavation has to be stopped.A monitor net was placed on the slope and the monitor result indicated that a slide mass has been *** with topography analysis,geological investigation i.e.,borehole exploration,geophysical investigation,it can be concluded that the slope where the power plant located is an overlooked giant ancient landslide during pre-stage investigation for site of hydropower plant,and the landslide is partially *** results indicated that the deformation of the slide is not even,the displacement of the head area is mainly vertical component,and the displacement of the toe area is mainly horizontal *** slide was induced by lots of drainage from No.2 access tunnel,the successive rainfall would accelerate the deformation, and the excavation of new provincial highway in toe area had a crucial effect on local deformation. The slide mass had experienced rainstorm seasons and it did not present severe deformation,thus the slide mass could be stable if drainage system including surface and underground is *** risk of blocking up Muli River is *** conclusions presented above have been verified in practice.

本文通过结合3D打印技术与软刻蚀技术制备了一种新型的微流道细胞培养系统(MPCCS)。该微流道培养体系具有可预先设计的细胞培养腔,用于细胞组织块培养。通过降解实验及数值模拟表明,微流道培养体系可以实现以下要功能:①调控营养物质的流动,减轻施加在细胞和支架上的剪切应力;②在降解过程中,保持支架的原始形态;③在支架降解时提供机械支撑。通过对于微流道系统内部的数值模拟,进一步表明流体在微流道灌注细胞培养系统(MPCCS)内部具有均匀的速度分布,可以为细胞培养提供均匀的营养供给。
