信息技术在医院病案统计中的应用

伴随着我国综合实力的不断提升,信息技术获得了突飞猛进的发展,如今,医疗改革如火如荼地进行,医院的信息管理工作同以往相比较也实现了极大的发展。病案统计工作是指相关工作人员对医院中患者的信息进行全面统计,若是这项工作完成得足够出色,会给医院后续的信息查询工作带来诸多方便和快捷,也能够在某种程度上使医院管理效率和质量实现一定幅度的提升。因此,将信息技术和医院的病案工管理工作进行密切结合,就成为病案管理人员应当重点思考的问题。病案统计工作是医院管理工作中的一个重点环节,病案统计结果能够为医院整体绩效带来十分深远的影响。因此,投入更多时间和精力来提高对这项工作的重视,显得十分关键和重要。文章对信息技术在医院病案统计中的应用展开了分析。     

Stock price prediction based on LSTM and LightGBM hybrid model

Finding an accurate, stable and effective model to predict the rise and fall of stocks has become a task increasingly favored by scholars. This paper proposes a long short-term memory (LSTM) network based on Pearson's correlation coefficient and a Bayesian-optimized LightGBM hybrid model, named as LSTM-BO-LightGBM, to solve the problem of stock price fluctuation prediction. The multilayer bidirectional LSTM-BO-LightGBM prediction model is compared with the LSTM-BO-XGBoost hybrid model, the LSTM-LightGBM hybrid model, the LSTM-XGBoost hybrid model, the single LSTM network model and the RNN network model. The prediction result of the LSTM-BO-LightGBM model for the "ES?=?F" stock is an RMSE value of 596.04, MAE value of 15.24, accuracy value of 0.639 and f1_score value of 0.799, which are improved compared with the prediction results of the other five models. At the same time, when applying the model to "YM?=?F", "CL?=?F", "^TNX", "^N225", "NQ?=?F", "AAPL", "GC?=?F", "JPY?=?X" and "SI?=?F", all of the nine stocks showed good forecasting performance. The results demonstrate that the multilayer bidirectional LSTM-BO-LightGBM model proposed in this paper has better approximation ability and generalization ability in the stock fluctuation forecast than previous models and can well fit the stock fluctuation.

陕西汉阴县黄龙金矿成矿物质来源及成矿模式探讨

陕西省汉阴县黄龙金矿位于陕西石泉-旬阳金矿带整装勘查区中部,是区内重点调查的典型矿床之一,本次工作通过对黄龙金矿不同地质体的氢氧同位素、硫同位素、石英包裹体均一温度及稀土元素等方面的研究,以及成矿物理化学条件的分析,结合矿体地质特征,认为黄龙金矿床成矿物质是多源的,主要来源有3个方面:(1)中-下志留统梅子垭岩组;(2)煌斑岩脉;(3)早期剥离断层。通过对该矿床成矿物质来源及区内构造变形特征分析,建立了黄龙金矿岩浆热液叠加改造型金成矿模式图。为区内寻找同类型金矿床提供新的思路。     

Quantitation of ochratoxin a in cereals and feedstuff using sequential injection analysis with luminescence detection

Ochratoxin A is one of the most important mycotoxins due to its global incidence and toxicity. Therefore, many countries have adopted regulations or guidelines to limit exposure and protect human and animal health. In this paper, we have developed two different flow-through optosensors using sequential injection analysis, and compared them in terms of analytical parameters. One of them used fluorescence detection, whereas the other one used terbium-sensitized luminescence detection. In both cases, an appropriate solid support was placed inside the flow-cell to retain the analyte and increase the selectivity and sensitivity of the system.The extraction of ochratoxin A from cereals and animal feedstuff was performed with a modified QuEChERS method. The obtained detection limit made it possible to fulfill the Commission of the European Communities Recommendation guidance values for this contaminant in feed. Recovery experiments were carried out in cereals and several feed samples at different fortification levels. Recoveries in the 86–112% range were obtained, therefore demonstrating the applicability of the proposed analytical method for quality control analyses.     

A new polyanion with Dawson-like constitution: [H2SeW18O60]6 −

A new tungstoselenite, [H₂SeW₁₈O₆₀]^6 −, was isolated under acidic medium conditions (pH = 1.7)with the monoprotonated ethylamine as cation. It represents the first example of Se-containing polyoxometalate with unusual Dawson-like construction and has fully been characterized both in solid state and in solution. The high-resolution ESI-MS confirmed that the polyanion at least contains two protons and its proton number can be up to six in solution.
