“Kunstlehre” and Applied Phenomenology  [PDF]
Wen-Sheng Wang
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.32048
Abstract: This article attempts to clarify the ambiguity or double sense of “Kunstlehre” by Husserl and Gadamer, and emphasizes “Kunstlehre” as pure science that originated in Aristotle’s evaluation of theoría, and as fine art, or as the nature or quasi-nature of “as if”, according to Kant’s idea. Aristotle’s concept of phrónesis will be also regarded as a kind of natural “as if”, and considered as “Kunstlehre”. Gadamer’s philosophical hermeneutics makes a high level or deep theoretical reflection on the “Kunst” of understanding. He founds his hermeneutics under phrónesis, which will be discussed in detail. Regarding the application of “Kunstlehre” to a practical research, this article shows a contribution by Hersch, and explains how phrónesis is actualized in a case study by him. In the end, “Kunstslehre” will be pointed out as a process of exercise with time whereby Sensus communis functions as a principle (arché) of Gadamer’s hermeneutics, and makes the process of the formation of phrónesis possible

Abstract: We use the Monte Carlo method to study the two types of devices used in the technique of single electron spectroscopy and get the C-V curve and I-V curve of them. The results compare well to approximate analytical expressions. Furthermore, with great prospects, we may take into account such effects as cotunneling and coupling between quantum dots through the combination of Monte Carlo method and other numerical methods.
CLeFAPS: Fast Flexible Alignment of Protein Structures Based on Conformational Letters
Sheng Wang
Quantitative Biology , 2009,
Abstract: CLeFAPS, a fast and flexible pairwise structural alignment algorithm based on a rigid-body framework, namely CLePAPS, is proposed. Instead of allowing twists (or bends), the flexible in CLeFAPS means: (a) flexibilization of the algorithm's parameters through self-adapting with the input structures' size, (b) flexibilization of adding the aligned fragment pairs (AFPs) into an one-to-multi correspondence set instead of checking their position conflict, (c) flexible fragment may be found through an elongation procedure rooted in a vector-based score instead of a distance-based score. We perform a comparison between CLeFAPS and other popular algorithms including rigid-body and flexible on a closely-related protein benchmark (HOMSTRAD) and a distantly-related protein benchmark (SABmark) while the latter is also for the discrimination test, the result shows that CLeFAPS is competitive with or even outperforms other algorithms while the running time is only 1/150 to 1/50 of them.
Hydropathy Conformational Letter and its Substitution Matrix HP-CLESUM: an Application to Protein Structural Alignment
Sheng Wang
Quantitative Biology , 2010,
Abstract: Motivation: Protein sequence world is discrete as 20 amino acids (AA) while its structure world is continuous, though can be discretized into structural alphabets (SA). In order to reveal the relationship between sequence and structure, it is interesting to consider both AA and SA in a joint space. However, such space has too many parameters, so the reduction of AA is necessary to bring down the parameter numbers. Result: We've developed a simple but effective approach called entropic clustering based on selecting the best mutual information between a given reduction of AAs and SAs. The optimized reduction of AA into two groups leads to hydrophobic and hydrophilic. Combined with our SA, namely conformational letter (CL) of 17 alphabets, we get a joint alphabet called hydropathy conformational letter (hp-CL). A joint substitution matrix with (17*2)*(17*2) indices is derived from FSSP. Moreover, we check the three coding systems, say AA, CL and hp-CL against a large database consisting proteins from family to fold, with their performance on the TopK accuracy of both similar fragment pair (SFP) and the neighbor of aligned fragment pair (AFP). The TopK selection is according to the score calculated by the coding system's substitution matrix. Finally, embedding hp-CL in a pairwise alignment algorithm, say CLeFAPS, to replace the original CL, will get an improvement on the HOMSTRAD benchmark.
Impacts of oasis on the atmospheric hydrological cycle over the nearby desert  [PDF]
Qiang Zhang, Yuhe Nan, Sheng Wang
Natural Science (NS) , 2010, DOI: 10.4236/ns.2010.27084
Abstract: Using the data of “A field experiment on landatmosphere interaction over arid region in Northwest China” carried out in Dunhuang of Gansu Province from May to June 2000; Characteristics of the atmospheric humidity over desert and Gobi near oasis in the Northwest China Arid Region are analyzed. According to the difference of the characteristics in different wind directions, the impacts of oasis on atmospheric hydrological cycle over desert and Gobi near it are revealed. The relation of atmosphere inverse humidity and negative water vapor flux to wind direction and atmospheric stability is studied. It shows that distribution of the atmosphere inverse humidity is inconsistent with that of the negative water vapor flux; sometimes 1-hour-average value demonstrates the characteristic of counter-gradient transfer. And the diurnal variation of distribution of the counter-gradient transfer and the effect of atmospheric stability on the counter-gradient transfer are also given.
Spousal concordance in academic achievements and IQ: A principal component analysis  [PDF]
Yue Pan, Ke-Sheng Wang
Open Journal of Psychiatry (OJPsych) , 2011, DOI: 10.4236/ojpsych.2011.12003
Abstract: Assortative mating, the tendency for mate selection to occur on the basis of similar traits plays an essential role in understanding the genetic variation on academic achievements and intelligence (IQ), it is also an important mechanism explaining spousal concordance. We used a subset of The Collaborative Study on the Genetics of Alcoholism sample to study the mating patterns in 84 pairs of spouses from Caucasian families with their academic achievements (reading, spelling, arithmetic, vocabulary and comprehension) and IQ (verbal IQ, performance IQ and full scale IQ). Simple correlation analysis showed that 6 of these 8 traits revealed evidence of spousal correlation (P < 0.05). The first principal component (PC1) of husbands explains 73.61% for the variation in the eight variables, which has high loadings from reading, spelling, arithmetic, verbal IQ and full scale IQ while PC1 of wives explains 72.86% for the variation in the eight variables, which has high loadings from reading, spelling, verbal IQ and full scale IQ. There was highly significant positive correlation between spouses by PC1 (P < 0.0001). The new variable PC1 may be important in spousal concordance and mate selection in society and act upon achievements and intelligence levels.
Wireless Bioradar Sensor Networks for Speech Detection and Communication  [PDF]

Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.55B008
Abstract: Wireless multimedia sensor networks (WMSN) are emerging to serve for the collection of acoustic and image information. In the WMSN, the microphone is usually employed to function as sensor nodes for the acquisition of acoustic data. However, those microphone sensors are needed to be placed close with sound source and cannot detect sound signal through certain obstacles. To overcome the shortcomings of microphone sensor, we develop a new type of bioradar sensor to achieve non-contact speech detection and investigate theoretically the mechanism of bioradar for speech detection. Results show that the system can successfully detect speech at some distance and even through non-metallic objects with certain thickness. In addition, in order to suppress the noise and improve the quality of the detected speech, we use spectral subtraction and Wiener filtering algorithm respectively to enhance the bioradar speech and evaluate the performance of the two methods using spectrogram.

Sheng Ma, Xiongbin Wang, Huachuan Hu
Journal of Applied Mathematics and Physics (JAMP) , 2017, DOI: 10.4236/jamp.2017.510163
Abstract: In recent years, since airspace restrictions and the volume of passenger traffic are increasing, the rate of flight delay is rising rapidly and the contradiction about it is outstanding. Flight delay event not only holds up passengers’ time, but also makes the airlines suffer a lot. So a scientific and reasonable guidance is necessary to reduce the delay effect. This paper firstly establishes a method to assess the degree of airport delays and get all factors which caused the flight delays quantification, and ultimately we offer a proposal to deal with the flow factor, which is the principal reason for flight delays.

Journal of Water Resource and Protection (JWARP) , 2015, DOI: 10.4236/jwarp.2015.711068
Abstract: We focused on the need for the phosphorus removal in water plant process. As for surface water plant, the enhancement of phosphorus removal in purification process can raise the biological stability of effluent potable water. This study conducted the effect of two water treatment processes for phosphorus removal, including the PAC + AAL (the treatment process using poly aluminum chloride and activated aluminum oxide) and PFS + AAL (the treatment process using poly ferric sulfate and activated aluminum oxide). The aim is to use the adsorption capacity of activated aluminum oxide to increase the removal of phosphorus in filtration process. The result showed that the two processes both can remove the phosphorus concentration to reach below 10 μg/L, and the PAC + AAL is the better process.

Abstract: Winter wheat is the main food crop in China. Gansu Province is a traditional winter wheat growing area, and its planting range is limited by the thermal conditions of winter. The average temperature in Gansu Province increased by 0.28°C per decade, higher than the China’s and global average, and the warming in winter was more obvious. Therefore, it is necessary to study the climate suitability and vulnerability of winter wheat planting in Gansu. In this paper, the maximum entropy model Maxent and Arcgis software are used to select six major climatic factors including annual total radiation, annual precipitation, the warmest monthly average temperature, the coldest monthly average temperature, annual average temperature, and annual extreme minimum temperature, which construct winter wheat planting distribution-climate relationship model that studies the climate suitability and vulnerability of winter wheat during the period 1961-2015. Studies have shown that the average cold weather and annual extreme minimum temperature are the most important climatic factors affecting winter wheat in Gansu, which can reflect the low temperature conditions that winter wheat can tolerate. However, the main winter wheat planting areas in Gansu Province are distributed in arid and semi-arid rain-fed agriculture areas. Precipitation and total annual radiation are also very important constraints. At the same time, climate change has little effect on winter wheat in Gansu Province, and the area of suitable area fluctuates slightly. It shows moderate adaptation in each evaluation period.
