This paper focuses on word difficulty prediction and classification on the basis of capturing a year's word game data. Although Wordle was all the rage, recent tracking data shows that the Wordle popularity appears to be declining gradually, and the number of players has a downward trend. To promote the healthy development of Wordle and assist game developers in adjusting their game strategies in time, this paper establishes a word difficulty prediction model. Before Wordle difficulty prediction model is established, we preprocessed the data, rasterizing the area to be studied. In phase I, we introduced a PSO-LSTM prediction model and performed specific training, achieving an accuracy rate of over 85%. After coding the letters in "EERIE", we successfully obtained the percentage of word "EERIE" on March 1,2023 will appear. The second phase uses hierarchical clustering analysis to subcategorize words by difficulty. The difficulty of words is then divided into five levels based on the folded graph of clustering coefficients derived from the elbow rule. Finally, this paper presents a model accuracy test and suggests the idea that this model can predict the data of serial relationship within the existence time and can be extended to the evaluation and weighted ranking under the influence of other factors.
A kind of minimum mean square error linear equalizer (MMSE-BLE) algorithm is presented for the solution on channel capacity of single-carrier code division multiple accesses (SC-CDMA) system, this algorithm received data symbol vector multiplied by covariance matrix by using Wiener estimator, and gets the decorrelation of multiple access interference (MAI), inter-symbol interference (ISI) and noise. MMSE-BLE algorithm calculates the channel capacity with MMSE criterion algorithm, so that it can analyze the multi-user uplink channel capacity of space-time coding SC-CDMA system under the multipath conditions effectively. The simulation results show that the number of user, path, transmitting and receiving antennas, multipath diversity gain, etc. All of them have an impact on the capacity of multi-user system, it seems that multiple antennas should be used for reception to get single-path diversity gain in frequency selective channels.
In spite of the impressive progress in the investigation of hepatic encephalopathy (HE), the complex mechanisms underlying the onset and deterioration of HE are still not fully understood. Currently, none of the existing theories provide conclusive explanations on the symptoms that link liver dysfunction to nervous system disorders and clinical manifestations. This paper summarized the diagnostic and therapeutic approaches used for HE in modern medicine and traditional Chinese medicine and provided future perspective in HE therapies from the viewpoint of holistic and personalized Chinese medicine.
In order to treat the data of sample plot in forestry scientific research effectively, the treatment system of experiment sample plot of experiment stand (ESSSTS1.0) was exploited using Visual FoxPro6.0(Chinese Version) as developing tool.In the system, forms and controls are used, with database.The system is easy to operate with freindly interface. The system include building sample plot database,logging in,editing,modifying,statistics and analyzing,comprehensive sample calculate and result output.The system can be used in comprehensive sample calculate and diameter size statistics and the sample plot site evaluation.
With the change of life style, more and more people are eating out, and the dietary content is high in calories, fat and sugar, resulting in the increasing number of obesity in children, adolescents and adults, and the prevalence of chronic diseases continues to grow. Therefore, preventive health care has become the focus of health policy in the 21st century. The pursuit of health must start from the daily diet. This paper proposes an intelligent recipe recommendation model based on integer planning, which customize personalized balanced diet according to the limitations of food type and meal cost and other restrictions.
ABSTRACT. Pyrotheca hydropsycheae n. sp. is described from caddis fly larvae, Hydropsyche siltalai Döhler, 1963. All stages were found in oenocytes and fat body cells. Meronts were uni‐ or binucleate with simple surface membranes. The sporogonic stages were recognized ultrastructurally by the separation of an envelope, the sporophorous vesicle, from their surfaces. Mature sporogonial plasmodia were tetranucleate and gave rise by longitudinal fission to four uninucleate elongate sporoblasts with polar nuclei. Spores were lageniform with an inflated posterior end, containing the polar tube coils and the nucleus, and a narrow anterior section comprising two‐thirds of the length, containing the polaroplast and straight part of the polar tube. The polaroplast consisted of an anterior region of loosely packed membranes arranged as partitions at angles to one another and a posterior region of increasingly closely packed parallel membranes. The spore wall consisted of an electron‐dense exospore with a fuzzy coat and a thin electron‐lucent endospore. All four spores derived from a sporont faced in the same direction in the sporophorous vesicle. Spores measured 8.7 μm long and extruded polar filaments were about 20 μm.
The study of species population change is one of the most classic topics in biology. In this paper, we consider not only intra-race competition but also competition between two species. It is assumed that the resources in the environment are finite in this paper. Improved on the Logistic Population Growth Model from Malthusian model, we built the Competitive Hunter Model for trout and bass referring to the Lotka-Volterra Model. In this paper, we presented the assumptions of the model and analyzed the equilibrium points of the model in numerical analysis and the typical trajectories in phase planes in graphical analysis.
