RETRACTED: Factor Analysis for Financial Performance Evaluation of Listed Chinese Medicine Companies
(2022-01-01)
Wang, Jin
Coastal city enterprises are directly related to people's health and are considered to be a sunrise industry that does not fall, while the 14th Five-Year Plan proposes to vigorously develop coastal city enterprises. In this paper, the financial data of 20 coastal city enterprises in 2019 were selected as samples, and an index system reflecting the characteristics of coastal city enterprises was constructed and analyzed by factor analysis to obtain objective enterprise performance scores and rankings. The results show that the Chinese medicine industry has large disparities at different levels but relatively small disparities in the overall ranking. The highest overall score is Yunnan Baiyao, the highest profitability and shareholder return score is Jichuan Pharmaceutical, Ealing Pharmaceutical has the strongest solvency, Baiyunshan is the best at corporate asset inventory management, Yunnan Baiyao has the greatest asset expansion, and the Zhongheng Group has the best quality of accounts receivable. It is recommended that Chinese medicine companies should take into account their own situation, strengthen their core competitive ability, and improve their corporate performance.

The purpose of this review is to reveal the lipid and protein contents in black soldier fly larvae (BSFL) for the sustainable production of protein and energy sources. It has been observed from studies in the literature that the larval lipid and protein contents vary with the rearing conditions as well as the downstream processing employed. The homogenous, heterogenous and microbial-treated substrates via fermentation are used to rear BSFL and are compared in this review for the simultaneous production of larval protein and biodiesel. Moreover, the best moisture content and the aeration rate of larval feeding substrates are also reported in this review to enhance the growth of BSFL. As the downstream process after harvesting starts with larval inactivation, various related methods have also been reviewed in relation to its impact on the quality/quantity of larval protein and lipids. Subsequently, the other downstream processes, namely, extraction and transesterification to biodiesel, are finally epitomized from the literature to provide a comprehensive review for the production of unconventional protein and lipid sources from BSFL feedstock. Incontrovertibly, the review accentuates the great potential use of BSFL biomass as a green source of protein and lipids for energy production in the form of biodiesel. The traditional protein and energy sources, preponderantly fishmeal, are unsustainable naturally, pressingly calling for immediate substitutions to cater for the rising demands. Accordingly, this review stresses the benefits of using BSFL biomass in detailing its production from upstream all the way to downstream processes which are green and economical at the same time.

Retraction:All-optical switches based-on GaAs/AlAs quantum dots vertical cavities

In this paper, we present an all-optical switch based on self-assembled GaAs/AlAs quantum dots (QDs) within a vertical cavity. Two essential aspects of this novel device have been investigated, which includes the QD/cavity nonlinearity with appropriately designed mirrors and the intersubband carrier dynamics inside QDs. Verticalreflection- type switches have been investigated with an asymmetric cavity that consists of 12 periods of GaAs/Al0.8Ga0.2As for the front mirror and 25 periods for the back mirror. The thicknesses of the GaAs and AlGaAs layers are chosen to be 89 and 102 nm, respectively. To give a dot-in-a-well (DWELL) structure, 65nm dimension of Si was deposited within an 20nm AlAs QW. All-optical switching via the QD excited states has been achieved with a time constant down to 750 fs, wavelength tunability over 29.5 nm. These results demonstrate that QDs within a vertical cavity have great advantages to realize low-power consumption polarization-insensitive micrometer-sized switching devices for the future optical communication and signal processing systems. © 2010 Published by Elsevier Ltd.

This paper presents the automatic optical power and extinction ratio control of 4.25Gbps optical transceiver to optimize optical transmitting eye diagrams over operating temperature range. Optical eye diagrams are adjusted an optical power and extinction ratio over temperature following to quadratic equation and linear equation respectively which are calculated from the fitting curves of optical power and extinction ratio acquisition as the optical eye diagrams are optimized. The optimized eye diagrams are considered by zero hit mask margin test compliant with Fibre Channel standards. © 2008 IEEE.
