Time series analysis plays an important role in hydrologic forecasting,while the key to this analysis is to establish a proper model.This paper presents a time series neural network model with back propagation procedure for hydrologic forecasting.Free from the disadvantages of previous models,the model can be parallel to operate information flexibly and rapidly.It excels in the ability of nonlinear mapping and can learn and adjust by itself,which gives the model a possibility to describe the complex nonlinear hydrologic process.By using directly a training process based on a set of previous data, the model can forecast the time series of stream flow.Moreover,two practical examples were used to test the performance of the time series neural network model.Results confirm that the model is efficient and feasible. 展开更多

We analyze for the first time the rules of breaking in an X-palindrome between human and chimpanzee. Results indicate that although the overall changes that occurred in the human X-palindrome are fewer than in the chimpanzee, mutations occurring between the left arm and right arm were nearly equivalent both in human and chimpanzee when compared with orangutan, which implies evolutionary synchronization. However, there are many more A/T→G/C changes than G/C→A/T in a single arm, which would lead to an increasing trend in GC content and suggest that the composition is not at equilibrium. In addition, it is remarkable to find that there are much more asymmetrical nucleotide changes between the two arms of the human palindrome than that of the chimpanzee palindrome, and these mutations are prone to occur between bases with similar chemical structures. The symmetry seems higher in the chimpanzee palindrome than in the human X-palindrome. 展开更多

The geophysical mechanism behind astronomical time-latitude residuals (ATLR) are discussed. The photoelectric astrolabe at Yunnan Observatory (YO) observed apparent synchronous anomalous ATLR before the Wenchuan M8.0 earthquake (EQ) in May 12, 2008 and the Lushan M7.0 EQ n April 20, 2013. We compared the ATLR from the YO photoelectric astrolabe and EQ data since 1976. Anomalous ATLR was observed before several strong EQs in the Yunnan Province. We believe the photoelectric astrolabe can be used to predict strong EQs and the anomalous ATLR are a potential EQ precursor. 展开更多

A whole year analysis of riverine dissolved organic carbon (DOC) concentrations in the Xijiang River (XJR), South China, showed that the mean riverine DOC concentration (1.24 mg L-1) in the XJR was notably lower than the averaged value (5.75 mg L-1) of the global riverine DOC concentration in several major rivers. There is an inconspicuous monthly fluctuation of the DOC signal in the XJR, but on a semi-yearly time scale, however, the riverine DOC concentration had significant difference between hydrological seasons. The DOC level during the flood season (1.18 mg L-1) was less than that during the non-flood season (1.40 mg L-1). Owing to the concomitance of the flushing and dilution effects of the runoff during the high-water period, the variation of riverine DOC concentration with discharge in the XJR differed from that reported in many other major rivers. The DOC export flux above the city of Wuzhou was about 0.62× 106 g C km-2 yr-1. The DOC transported during the "056" Massive Flood period comprised 30.35% of the annual total, while the discharge accounted for 36.32% of the total annual flow. The characteristics in riverine DOC concentration in the XJR were attributed to the combined effect of the geomorphologic, monsoon climatic and hydrological processes as well as land-use within the drainage basin. 展开更多

Purpose: The purpose of this review was to critically analyse the cun;ent evidence investigating the effect of an athlete's hydration status on physical performance. Methods: A literature search of multiple databases was used to identify studies that met the inclusion criteria for this review. The included studies were then critically appraised using the Downs and Black protocol. Results: Nine articles were found to meet the inclusion criteria, with an average score of 79% for methodological quality representative of a "high" standard of research. Conclusion: The evidence suggests that dehydration has a negative impact on physical performance for activities lasting more than 30 s in duration. However dehydration was found to have no significant impact on physical performance for activities lasting less than 15 s in duration. 展开更多

This essay is twofold: the first part focuses on the interpretation of the concept of Hell in Dante's Inferno and Italian culture as depicted in Last Judgment scenes such as Giotto's in the Arena Chapel of Padua; Signorelli's in the Orvieto Cathedral; and Michelangelo's in the Sistine Chapel in Rome. The second part deals with the drawing illustrations for the text of Dante's Divine Comedy composed by the Florentine painters Sandro Botticelli, Giovanni Stradano, and Federico Zuccaro. Here the emphasis is on Dante's Inferno, which comments upon Neoplatonic personalities, Florentine politics, and current popular art. Comparisons with some of Botticelli's, Stradano's, and Zuccaro's drawing illustrations indicate the assimilation of classical artistic concepts such as Horace's ut pictura poesis [as is painting so is poetry] as well as Plato'sfurorpoeticus [poetical inspiration] promoted in the writings of Marsilio Ficino, a Renaissance Neoplatonic philosopher. 展开更多

Since time and beyond, when humans first developed the understanding of staying in communities, a sense of affection and adoration grew towards fellow beings. The law of nature of the cycle of life gave rise to the belief in life after death and a sense of intimidation for the same, gave way to supernatural beliefs. Such beliefs gave rise to multifarious customary activities. A study to understand them on the basis of symbolism has paved the way for simplification of the complex rituals, and hence, perceive the prevalent socio-cultural aspects of those times. 展开更多

The current financial turmoil in the United States has been attributed to multiple reasons including healthcare expenditure.Health care spending has increased from 5.7 percent of the gross domestic product(GDP) in 1965 to 16 percent of the GDP in 2004.Healthcare is driven with a goal to provide best possible care available at that period of time.Guidelines are generally assumed to have the high level of certainty and security as conclusions generated by the conventional scientific method leading many clinicians to use guidelines as the final arbiters of care.To provide the standard of care,physicians follow guidelines,proposed by either groups of physicians or various medical societies or government organizations like National Comprehensive Cancer Network.This has lead to multiple tests for the patient and has not survived the test of time.This independence leads to lacunae in the standardization of guidelines,hence flooding of literature with multiple guidelines and confusion to patients and physicians and eventually overtreatment,inefficiency,and patient inconvenience.There is an urgent need to restrict articles with Guidelines and develop some strategy like have an intermediate stage of pre-guidelines and after 5-10 years of trials,a systematic launch of the Guidelines.There can be better ways than this for putting together guidelines as has been suggested by multiple authors and researchers. 展开更多

In megacities, the phenomenon of the highrise buildings which add fashion elements into the body and facades seems as big sculptures. Architect composed their work by applying the cross-pollination of design method. They adopted the various elements to enrich their building's facade in order to look different. On the other hand, the traditional architecture expressed the tribe civilization by placing their proud artifacts into the building's facade. The purpose of this study is to find a new theory of architecture during their process of becoming of the architecture's form. The study applied a phenomenological investigation method of several highrise building's facade at Jakarta and several districts of Singapore, Brisbane and Melbourne. The study result is a new theory named "the fashion-architecture" is a building composed by adopting the cross-pollination of design method. To enrich the building's facade, architect adopted anything including the fashion's design elements: accessories, millineries, and cosmetics also reflected by the traditional architecture. Their fashion-architecture works are reflecting the tribe civilization into a contemporary architecture design. 展开更多

Shared Memory (SM) switches are widely used for its high throughput, low delay and efficient use of memory. This paper compares the performance of two prominent switching schemes of SM packet switches: Cell-Based Switching (CBS) and Packet-Based Switching (PBS).Theoretical analysis is carried out to draw qualitative conclusion on the memory requirement,throughput and packet delay of the two schemes. Furthermore, simulations are carried out to get quantitative results of the performance comparison under various system load, traffic patterns,and memory sizes. Simulation results show that PBS has the advantage of shorter time delay while CBS has lower memory requirement and outperforms in throughput when the memory size is limited. The comparison can be used for tradeoff between performance and complexity in switch design. 展开更多

This paper, that has been introduced at the annual meeting of the Renaissance Society of America (Washington, March 22, 2012), is a little part of a wider research about migration and movements of people between Western and Eastern Europe (and vice versa) that, started one year ago, is still in progress. Despite a common thought that had considered, still in 15th century, Hungarians as unculturished and violent people, the town of Ferrara, ruled by the Estes, had welcomed many of them during the 15-16th centuries. They were, above all, and as the sources testify, literati and students. This paper tries to show and analyze the cultural reasons and the background that have determined Hungarians' presence in Ferrara during the Renaissance, with the consciousness that if many sources have been studied, many others must be 展开更多

Under global climate change, drought has become one of the most serious natural hazards, affecting the ecological environment and human life. Drought can be categorized as meteorological, agricultural, hydrological or socio-economic drought. Among the different categories of drought, hydrological drought, especially streamflow drought, has been given more attention by local governments, researchers and the public in recent years. Identifying the occurrence of streamflow drought and issuing early warning can provide timely information for effective water resources management. In this study, streamflow drought is detected by using the Standardized Runoff Index, whereas meteorological drought is detected by the Standardized Precipitation Index. Comparative analyses of frequency, magnitude, onset and duration are conducted to identify the impact of meteorological drought on streamflow drought. This study focuses on the Jinghe River Basin in Northwest China, mainly providing the following findings. 1) Eleven meteorological droughts and six streamflow droughts were indicated during 1970 and 1990 after pooling using Inter-event time and volume Criterion method. 2) Streamflow drought in the Jinghe River Basin lagged meteorological drought for about 127 days. 3) The frequency of streamflow drought in Jinghe River Basin was less than meteorological drought. However, the average duration of streamflow drought is longer. 4) The magnitude of streamflow drought is greater than meteorological drought. These results not only play an important theoretical role in understanding relationships between different drought categories, but also have practical implications for streamflow drought mitigation and regional water resources management. 展开更多

The voice of calling for humanistic concern is always from uncountable doctor-patient conflicts, from which we often hear a doctor is killed or injured for disputes. Prejudice has been rooted in mind that all doctors and nurses are interest-centered and cold-blooded. To some extent, it's true that patterned questions with a poker face are always more than gentle words with warm smile. Nurses are the ones who keep patients company for the longest time. Therefore, caring matters more for them. The explicit concept of "caring" will be introduced and we will attach great importance to how nurses can achieve caring. From the following aspects:the practices of loving kindness, the instillation of faith and hope, sensitivity to indicators of disease, improvem ent of healing environment, communication arts etc, you will understand why nurse is the symbol of angel. We can begin with caring about people around us. Our duty is not only to deal the ill but to warm the chill. 展开更多

There is the question--can we hope that humanism and erudition can redevelop nowadays? In the long history of humanistic inheritance, from ancient times till the end of the 18th century, there was obvious decadence of essential humanistic points. As the historial period, humanism means revival of classical culture, and as a specific culturological phenomenon, it means erudite education created by Hellens and developed by Romans, who recovered "humanitas" as global education. Italy was the first who helped humanists to contemplate on classical culture; and in post-medieval age, Italian humanists achieved a supreme measure of humanism through their "humanistic studies." We will try to point out good achievements of humanism erudite education in European culture in later epochs. Humanism leads man to turn over to world--after medieval stricture--and it becomes self-conscious revolution, what we can see in Latin literature till the 18th century. Rise of individualism, development of libraries and humanistic academies give chance to latin tradition in European literature as universal discipline, including erudite education in international corpus (Ragusa also). High-intellectual and latinized elites with humanistic state of mind develop complex spiritual inteligency with science requests in later epochs too. We will try to explain in which degree humanism, with its synthetic point of view, influences on later corpus of European literary themes and how great its actuallity is nowdays. 展开更多
