The article discusses the application of RPA (Robotic Process Automation) technology in financial management and demonstrates its remarkable effectiveness in improving efficiency and reducing costs. The article establishes an automated accounting method for enterprise finance using RPA technology through statistical analysis, classification processing, and feature extraction of enterprise financial data. The consistency check method is used to verify the fit and reasonableness of the method. Practically applied to the financial accounting process of Enterprise A, the method dramatically reduces the time for reconciling bonds and funds from 60 minutes to 2 seconds, significantly improving the accounting efficiency. In addition, the method ensured that the accuracy of statement filling reached 100% and reduced the labor cost of enterprise accounting from 17.58 million yuan to 6.88 million yuan, a reduction of 2.56 times. The article emphasizes that the established financial accounting method increases the enterprise’s profitability and lays a solid foundation for the development of financial accounting automation.

“…DLAs are promising candidates for realizing future compact and low-cost particle accelerators due to their high energy gain per unit length, which is second only to that of laser-plasma accelerators. [18][19][20][21][22][23][24] In addition, DLAs have the advantage of easy integration of cascade acceleration. [25][26][27] The design of effective micro/nano dielectric structures to generate accelerating fields driven by input lasers is a critical research topic for DLAs.…”

Dielectric laser accelerator (DLA) is a promising technology for achieving high gradient acceleration in a compact design. Its advantages include ease of cascading and energy gain per unit distance that can exceed that of conventional accelerators by two orders of magnitude. This paper establishes rules for efficient particle acceleration using dielectric structures based on basic equations, proposes a design principle for DLA structures with clear physical images, and verifies the accuracy of the corresponding energy gain formula. DLA structures with different specifications, materials, and geometric shapes are constructed, and the achievable acceleration gradient is calculated. Our results demonstrate that effective acceleration can be achieved when the electric field sensed by particles in the acceleration cavity has zero frequency, which provides a powerful method for designing such devices. Furthermore, we demonstrate that the simplified formula for calculating energy gain presented in this paper can accurately determine the energy gain of particles during the design of dielectric accelerator acceleration structures.

“…For example, a class of Raman-type instabilities may be stabilized in a leaky density channel [18,19] and good stable laser transmission with high quality in inhomogeneous plasmas can be achieved in a hollow channel [20][21][22][23][24][25]. In addition, recent work on the development of q-Gaussian, super-Gaussian and quadruple Gaussian lasers [26][27][28][29][30][31][32] may inspire investigation of laser guiding in non-parabolic channels. In experiments, various channel structures can be achieved by controlling some of the experimental parameters [4,7,[33][34][35].…”

By containing ponderomotive self-channeling, the propagation behavior of an intense laser beam and the physical conditions are obtained theoretically in a radial power-law plasma channel. It is found that ponderomotive self-channeling results in the emergence of a solitary wave and catastrophic focusing, which apparently decreases the region for stable propagation in a parameter space of laser power and the ratio of the initial laser spot radius to the channel radius (RLC). Direct numerical simulation confirms the theory of constant propagation, periodic defocusing and focusing oscillations in the parameter space, and reveals a radial instability which prevents the formation of bright and dark solitary waves. The corresponding unstable critical curve is added in the parameter space numerically and the induced unstable region above the unstable critical curve covers that of catastrophic focusing, which shrinks the stable region for laser beams. For the expected constant propagation, the results reveal the need for a low RLC. Further study illustrates that the channel power-law exponent has an obvious effect on the final stable region and laser propagation, for example increasing this exponent can enlarge the stable region significantly, which is beneficial for guiding of the laser and increases the lowest RLC for constant propagation. Our results also show that the initial laser amplitude has an apparent influence on the propagation behavior.
