＂Heaven＂ and ＂Man＂ under the Reconstitution of the Confucianism -- from ＂Heaven and Man Being Related＂ to ＂Heaven and Man Being in One＂

Through analysis of the relationship between heaven and man and the development of the ideology in the developing process from the pre- Qin Confucianism, the cosmology Confucianism of the Han Dynasty to the formation of the Confucian School of idealist philosophy of the Song and Ming dynasties, this paper attempts to explore the Confucianism ideology from social structure, cultural integration and environmental change and so on, so as to points out that Confucianism does not collapse with the disintegration of the social structure; instead,it realizes self- reconstruction and renovation.

Petrographic and Geochemical Characteristics of the Pouni Palaeoproterozoic Formations North of the Léo Square Degree (Burkina Faso, West Africa)

The Pouni area is made up of basalts belonging to the Boromo belt, lamprophyres and granitoids. These geological formations are similar to geological formations of the same type in other regions of the Palaeoproterozoic domain of the Man/Leo shield. This study, which focused on the petrographic and geochemical characteristics of these geological formations, led to the following main conclusions: The lamprophyres are basic plutonic rocks that cut through other geological formations. The basalt belongs to the northern part of the Borormo belt and is thought to be a relic of overthickened oceanic plateaus. There are two groups of granitoid rocks. The granodiorite has a geochemical signature close to that of Archean TTGs and is metaluminous in character. It has a low potassium content. The minor element and rare earth element spectra indicate that it could be derived from partial melting of basic magmatic rocks. Biotite granites are peraluminous and highly potassic. Minor element contents and rare earth spectra indicate that they could be derived from partial melting of felsic materials. Geotectonic diagrams show that the granitoids identified in the Pouni zone were emplaced in an active tectonic context, similar to that of present-day subduction zones.

Petrographic and Geochemical Characteristics of the Granitoids in the South of Godé (North of the Square Degree of Léo-Burkina Faso, West Africa)

South of Godé, in the central-western region of Burkina Faso, granitoids of Paleoproterozoic age are similar to those of the Man/Leo shield. This study focused on the petrographic and geochemical characteristics of these granitoids, with the following results: 1) The tonalite that outcrops in the south-west of the study area belongs to the TTG group or first generation granitoids. They are most often ribboned at outcrop and have a geochemical signature close to that of Archean TTGs. Tonalite has a metaluminous character and the REE spectrum indicates that it may be derived from partial melting of basic magmatic rocks. 2) Biotite granites have no outcrop structure. They are weakly metaluminous to peraluminous and potassic to highly potassic. Their rare earth spectra indicate that they may be derived from the partial melting of TTG granitoids. 3) Geotectonic diagrams show that the granitoids studied to the south of Godé were emplaced in an active tectonic context similar to that of present-day subduction zones.

Fast solution to the free return orbit's reachable domain of the manned lunar mission by deep neural network

It is important to calculate the reachable domain(RD)of the manned lunar mission to evaluate whether a lunar landing site could be reached by the spacecraft. In this paper, the RD of free return orbits is quickly evaluated and calculated via the classification and regression neural networks. An efficient databasegeneration method is developed for obtaining eight types of free return orbits and then the RD is defined by the orbit’s inclination and right ascension of ascending node(RAAN) at the perilune. A classify neural network and a regression network are trained respectively. The former is built for classifying the type of the RD, and the latter is built for calculating the inclination and RAAN of the RD. The simulation results show that two neural networks are well trained. The classification model has an accuracy of more than 99% and the mean square error of the regression model is less than 0.01°on the test set. Moreover, a serial strategy is proposed to combine the two surrogate models and a recognition tool is built to evaluate whether a lunar site could be reached. The proposed deep learning method shows the superiority in computation efficiency compared with the traditional double two-body model.

The Violent Redemption Theme in A Good Man is Hard to Find

Flannery O’Connor is one of the representative figures of American Southern writers.Being recognized as the most outstanding writer of the American South after Faulkner,she has great influence in the literary world.Her works are always shrouded in a strange and grotesque atmosphere and full of death as well as religious metaphors.The protagonists are a series of American Southern freaks struggling with the crisis of spiritual belief.The protagonists of her novel A Good Man is Hard to Find are a hypocritical believer in the world of sinners and a lost man suffering in the midst of real sin,thus O’Connor uses the highest form of violence-death to bring ultimate redemption to them.In people’s conception,violence and redemption are often opposite to each other,but O’Connor uses bloody and violent plots to explore the theme of religious salvation,integrating and unifying the two contrary concepts to form her unique and profound violent redemption writing.

The Significance of Constructing TCM Psychosomatic Medicine from the Holistic View of the Unity of Nature and Man

With the development of medical technology, the problem of fragmentation of medical research has become increasingly prominent, and a series of iatrogenic diseases, drug-induced diseases and drug toxicity and side effects have resulted in an increase in the number of diseases. In the face of these problems, the medical concept has been re-examined and re-thought. The concept of the holistic view of the unity of nature and man in traditional Chinese medicine has certain enlightenment for dealing with the problems in the current medical development. Based on the holistic view of the unity of nature and man, the overall connection between human’s heart and body and nature is explained, and the further construction of TCM psychosomatic medicine is conducive to guiding the diagnosis and treatment of clinical diseases, and providing new enlightenment for the current medical concept thinking and clinical disease research.

Study on the Overload and Dwell-Fatigue Property of Titanium Alloy in Manned Deep Submersible

With the rapid development of ocean technology, the deep-sea manned submersible is regarded as a high-tech equipment for the exploration and exploitation of ocean resources. The safety of manned cabin has a decisive effect on the whole system. Ti-6 Al-4 V with the superior strength-to-weight ratio and corrosion resistance has been used for the manned cabin. The manned cabin experiences loading spectrum with different maximum stresses and different dwell time during their service life. The load sequence effects on dwell fatigue crack growth behavior of Ti-6 Al-4 V under different dwell time are investigated experimentally in this paper. The experimental results show that the crack tip plastic zone is enlarged by the dwell time and the overload retardation zone increases with dwell time under the same overload rate. A dwell fatigue crack growth model is proposed by modifying the crack tip plastic zone under the loading history with combinations of the single overload and dwell time factors are included in the modified model. Based on the experimental data, the overload retardation zone and the crack growth rates of Ti-6 Al-4 V are predicted by the modified model. A reasonable model for the load sequence effect on the dwell fatigue crack growth rates of Ti-6 Al-4 V is verified.

A Comparison of the Views of Heavenly Principles and Human Desire and the Theory of Personality Structure

This paper makes a comparative study of the theory of heavenly principles and human desires in the Neo-Confucianism of the Song and Ming Dynasties and the theory of personality structure in psychoanalytic theory.From the perspective of the construction of the subject,in the debate between the heavenly principle and the human desire,the person is built into the moral subject.The id,ego,and super-ego in the psychoanalytic theory constitute the unconscious structural subject.In the framework of these two theories,the“maintain the heavenly principles and eradicate human desires”and“the heavenly principles exist in desire”in the theory of heavenly principles and human desires express the unity of opposites between heavenly principles and human desire.The core of personality structure theory is the relationship of obedience and control among the id,ego,and super-ego.As far as the value orientation is concerned,the debate between the heavenly principle and the human desire provides a theoretical basis for the moral practice of Confucianism of“aim at absolute perfection”,while the free will of the id in the unconscious subject is the most essential ethical aspect of psychoanalysis.

Between the Heaven and Human Beings: On the Idea of the Heaven and the Transformation of Poetry in the Mid-Tang Dynasty

The relationship between the Heaven and human beings is a central issue in the transformation of Confucianism in the Mid-Tang Dynasty.The discourses on the Heaven by Han Yu,Liu Zongyuan,and Liu Yuxi helped to promote the transformation and greatly influenced the transformation in literature.The differences in the poetry among the three authors may also be interpreted from the perspective of their perceptions of the Heaven—Han Yu’s discourse on the Heaven focused on the enemy-relationship between the Heaven and human beings,so his poems always showed tension and loss.Liu Zongyuan was interested in the alienation between the heaven and human beings,so his poems were more rational and placid than Han Yu’s.However,Liu Yuxi’s discourse on the Heaven paid attention to the positive influence of the Heaven on human beings,and most of his poems were filled with reason.The changes in the relationship between the Heaven and human beings lead to the broadened themes,innovated vocabulary,diversified styles,and varied fresh imageries.Likewise,the relationship between the Heaven and human beings established in the Song Dynasty led accordingly to a new type of literature different from the Tang literature.

Urban Spectacle and Spectatorship in Edgar Allan Poe's "The Man of the Crowd"?

Edgar Allan Poe’s short story “The Man of the Crowd” delineates metropolitan visual experiences that relate to urban scenery and people. The anonymous first-person narrator, preoccupied with the social and psychological correlations between the city and wandering crowd, interprets his perception of the crowd as an inexhaustible spectacle. As the narrator experiences different phases of spectatorship, he ultimately realizes the inscrutability and impenetrability of the city through his observation of the old man of the crowd. This paper suggests that the narrator’s failure in seeing and reading the old man of the crowd renders an uncanny effect of urban spectatorship.

Joint waveform selection and power allocation algorithm in manned/unmanned aerial vehicle hybrid swarm based on chance-constraint programming

In this paper, we propose a joint waveform selection and power allocation(JWSPA) strategy based on chance-constraint programming(CCP) for manned/unmanned aerial vehicle hybrid swarm(M/UAVHS) tracking a single target. Accordingly,the low probability of intercept(LPI) performance of system can be improved by collaboratively optimizing transmit power and waveform. For target radar cross section(RCS) prediction, we design a random RCS prediction model based on electromagnetic simulation(ES) of target. For waveform selection, we build a waveform library to adaptively manage the frequency modulation slope and pulse width of radar waveform. For power allocation,the CCP is employed to balance tracking accuracy and power resource. The Bayesian Cramér-Rao lower bound(BCRLB) is adopted as a criterion to measure target tracking accuracy. The hybrid intelli gent algorithms, in which the stochastic simulation is integrated into the genetic algorithm(GA), are used to solve the stochastic optimization problem. Simulation results demonstrate that the proposed JWSPA strategy can save more transmit power than the traditional fixed waveform scheme under the same target tracking accuracy.

Metallic Reserves of Submarine Manganese Nodules to be Estimated and Harnessed Prudently: Evidence from China's Jiaolong Manned Submersible

Since the discovery of oceanic manganese nodules during the expedition of the British ocean-going ship Challenger from 1872 to 1876, research and development for seabed manganese nodules have never ceased owing to the huge economic inducements. Manganese nodules are the black or dark brown, spherical or massive Mn-bearing ores, deposits of which are found on the sea bottom. The nodules are a mixture of silicate and insoluble potassium permanganates （also with sub-Ti, Fe and Na permanganates） that contain more than 30 kinds of metallic elements, among which those of greatest economic interest are Mn （27-30%）, Ni（1.25-1.5%）, Cu（1- 1.4%）, Co（0.2- 0.25 %）, Fe, Si, and AI, with minor amounts of Ca, Na, K, Ti, B, H and O.

Using MAN and Coastal AERONET Measurements to Assess the Suitability of MODIS C6.1 Aerosol Optical Depth for Monitoring Changes from Increased Arctic Shipping

Collocated data of the moderate resolution imaging spectroradiometer (MO-DIS) Collection 6.1 aerosol optical depths (AOD) at 3 km × 3 km north of 59.9°N over ocean were assessed at 550 nm by aerosol robotic network (AERONET) data from coastal sites and marine aerosol network (MAN) data from vessels during June to October 2006 to 2018. Typically, MODIS AOD was higher at low and lower at high values than the AERONET AOD. Discrepancies were largest for sites where the Earth’s surface around the site is very heterogeneous (Canadian Archipelago, coast of Greenland). Due to the higher likelihood for sea-ice, MAN and MODIS AOD differed stronger west of Greenland and over the Beaufort Sea than at location in the Greenland and Norwegian Seas and Atlantic. MODIS AOD well captured the inter-seasonal variability found in the AERONET AOD data (R = 0.933). At all sites, MO-DIS and AERONET AOD agreement improved as time progressed in the shipping season, hinting at errors in sea-ice vs. open water classification. Overall 75.3% of the MODIS AOD data fell within the limits of the error envelops of the AERONET/MAN AOD data with MAN ranging between 87.5% and 100%. Changes in both MODIS and AERONET mean AOD between two periods of same length (2006-2011, 2013-2018) were explainable by changes in emissions for all sites.

Redefining Masculinity:A Comparative Study of Olive Schreiner’s The Story of an African Farmand Allan Grant’s The Woman Who Did

Illuminated by the idea that like women,Victorian men often felt the need to transgress or redefine the gender roles society assigned to them,I compared two distinguished New Women fictions The Story of an African Farm written by the pioneer New Woman Olive Schreiner,and The Women Who Did authored by Allen Grant to see how male characters embrace new models of masculinity.With a feminist perspective and a close textual reading approach,I intend to argue that the efforts male characters paid in redefining gender roles in embracing womanhood as free,fearless,and independent,accompanying them with love,understanding,and support have concerns for the integrity of both woman and men,and will lead to a healthy and beautiful human life.
