Chinese Stock Market Efficiency of Capital Allocation Function
Using the efficiency of capital allocation function to characterize the stock market system efficiency.Using panel data analysis method,from a regional perspective empirical analysisto implement the stock market during the capital allocation function efficiency issue approval system for China.The results show: the efficiency of resource allocation of China stock market is lower,and stock market system is inefficient.Point:Chinese stock market institutional change should transform from government-led to market-oriented and increase penalties for violations to cultivate rational and mature investors in order to achieve the stock market system function better,enhance system efficiency
You Can Generate It Again: Data-to-text Generation with Verification and Correction Prompting
Despite significant advancements in existing models, generating text
descriptions from structured data input, known as data-to-text generation,
remains a challenging task. In this paper, we propose a novel approach that
goes beyond traditional one-shot generation methods by introducing a multi-step
process consisting of generation, verification, and correction stages. Our
approach, VCP(Verification and Correction Prompting), begins with the model
generating an initial output. We then proceed to verify the correctness of
different aspects of the generated text. The observations from the verification
step are converted into a specialized error-indication prompt, which instructs
the model to regenerate the output while considering the identified errors. To
enhance the model's correction ability, we have developed a carefully designed
training procedure. This procedure enables the model to incorporate feedback
from the error-indication prompt, resulting in improved output generation.
Through experimental results, we demonstrate that our approach effectively
reduces slot error rates while maintaining the overall quality of the generated

Superconductivity and local-moment magnetism in Eu(FeCo)As
We report the measurements of resistivity and magnetization under magnetic
fields parallel and perpendicular to the basal plane, respectively, on a
cobalt-doped Eu(FeCo)As single crystal. We
observed a resistivity drop at 21 K, which shifts toward lower
temperatures under external fields, suggesting a superconducting transition.
The upper critical fields near show large anisotropy, in contrast with
those of other '122' FeAs-based superconductors. Low-field magnetic
susceptibility data also show evidence of superconductivity below 21 K. Instead
of expected zero-resistance below , however, a resistivity reentrance
appears at 17 K under zero field, coincident with the magnetic ordering of
Eu moments. Based on the temperature and field dependences of
anisotropic magnetization, a helical magnetic structure for the Eu spins
is proposed. External magnetic fields easily changes the helimagnetism into a
ferromagnetism with fully polarized Eu spins, accompanying by
disappearance of the resistivity reentrance. Therefore, superconductivity
coexists with ferromagnetic state of Eu spins under relatively low
magnetic field. The magnetic and superconducting phase diagrams are finally
summarized for both and .Comment: 8 pages, 10 figure
