Characteristics of the Function of Ice Force on Vertical Cylindrical Piles

A lot of tests on ice forces on vertical cylindrical piles are conducted in the ice basin of ice laboratory in Tianjin University to identify the characteristics of ice forces on fixed platforms in the Bohai Gulf. A function of ice forces is simplified on basis of test data, and the characteristics of the ice forces including the amplitude of the force and the breaking frequency of the ice sheet is detailed by use of the Fast-Fourier-Transform method, The results show that the ice breaking frequency presents a linear relationship with the ratio of ice moving velocity to ice thickness at low velocities. At high velocities, the frequency remains constant with the increase of the ratio of ice moving velocity to ice thickness. These conclusions are compared those published in literature.

The Centenary of the CPC: Leading the Times by Grasping the Laws and Trends of Historical Development

Discussions on grasping the laws and trends of historical development take a fundamental theoretical position in the scientific system of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era.Xi Jinping’s important statements have systematically answered such questions as what type of laws and trends of historical development should be followed,how did the Party follow the laws and trends of historical development in its centennial history,and how should the laws and trends of historical development be followed in a new era.The birth of the Communist Party of China(CPC),the victory of China’s War of Resistance against Japanese Aggression,the founding of the People’s Republic of China,and the unveiling of a new era for reform and opening up and socialism with Chinese characteristics are all the results of grasping the laws and trends of historical development.Over the past century,the Party has followed the laws and trends of historical development and continuously advanced the sinicization of Marxism on the basis of adhering to the unification between truth and values.In pursuit of“putting people first,”the Party has courageously been reforming itself and made relentless progress in the great endeavor of Party building.History shows that a keen appreciation of the laws and trends of historical development is an important sign of political maturity for a proletarian party.Only by applying Marxism according to current times and conditions will we keep abreast with the laws and trends of historical development.We should establish a broader concept of history and identify the laws and trends of historical development from the interactions and linkages between China and the rest of the world.We must recognize and promote the outstanding role of great leaders in steering the country in line with the laws and trends of historical development.

Comparison of brain functions between healthy participants and methamphetamine users with various addiction histories:Data analysis based on EEG and fNIRS

The electroencephalogram(EEG)rhythm and functional near-infrared spectroscopy(fNIRS)activation levels have not been compared between a healthy control group(HCG)and methamphetamine user group(MUG)with different addiction histories.This study used 64-electrode EEG and fNIRS to conduct an experiment that analyzed the resting and craving states.The EEG and fNIRS data of 56 participants were collected,including 14 healthy participants,14 methamphetamine users with an addiction history of 0.5–5 years,14 users with an addiction history of 5–10 years,and 14 users with an addiction history of 10–15 years.Isolated effective coherence(iCoh)within the brain network was used to process the EEG data.Statistical analysis was performed to compare differences in iCoh among the delta,theta,alpha,beta,and gamma bands and explore oxyhemoglobin activation levels in the ventrolateral prefrontal cortex,dorsolateral prefrontal cortex,orbitofrontal cortex,and frontopolar prefrontal cortex(FPC)of the control group.Finally,the Kmeans,Gaussian mixed model(GMM),linear discriminant analysis(LDA),support vector machine(SVM),Bayes,and convolutional neural networks(CNN)algorithms were used to classify methamphetamine users based on drug and neutral images.A 3-class accuracy was achieved.Changes in EEG and fNIRS activation levels of HCG and MUG with varied addiction histories were demonstrated.

A retrospective view on the history of natural sciences in XX-XXI

The presented paper is dedicated to a new ret-rospective view on the history of natural sci-ences in XX-XXI cc, partially including the sci-ence philosophy (mainly, the problems of the scientific realism, i.e. the correspondence of science to reality) and also a novel scheme for different classes of sciences with different ob-jects and paradigms. There are analyzed the chosen “great” and “grand” problems of phys-ics (including the comprehension of quantum mechanics, with a recently elaborated new chapter, connected with time as a quantum obs- ervable and time analysis of quantum processes) and also of natural sciences as a whole. The particular attention is paid to the interpretation questions and slightly to the aspects, inevitably connected with the world- views of the res- earchers (which do often constitute a part of the interpretation questions).

Scan of the endogenous retrovirus sequences across the swine genome and survey of their copy number variation and sequence diversity among various Chinese and Western pig breeds

In pig-to-human xenotransplantation,the transmission risk of porcine endogenous retroviruses(PERVs)is of great concern.However,the distribution of PERVs in pig genomes,their genetic variation among Eurasian pigs,and their evolutionary history remain unclear.We scanned PERVs in the current pig reference genome(assembly Build 11.1),and identified 36 long complete or near-complete PERVs(lc PERVs)and 23 short incomplete PERVs(si PERVs).Besides three known PERVs(PERV-A,-B,and-C),four novel types(PERV-JX1,-JX2,-JX3,and-JX4)were detected in this study.According to evolutionary analyses,the newly discovered PERVs were more ancient,and PERV-Bs probably experienced a bottleneck~0.5 million years ago(Ma).By analyzing63 high-quality porcine whole-genome resequencing data,we found that the PERV copy numbers in Chinese pigs were lower(32.0±4.0)than in Western pigs(49.1±6.5).Additionally,the PERV sequence diversity was lower in Chinese pigs than in Western pigs.Regarding the lc PERV copy numbers,PERV-A and-JX2 in Western pigs were higher than in Chinese pigs.Notably,Bama Xiang(BMX)pigs had the lowest PERV copy number(27.8±5.1),and a BMX individual had no PERV-C and the lowest PERV copy number(23),suggesting that BMX pigs were more suitable for screening and/or modification as xenograft donors.Furthermore,we identified 451 PERV transposon insertion polymorphisms(TIPs),of which 86 were shared by all 10 Chinese and Western pig breeds.Our findings provide systematic insights into the genomic distribution,variation,evolution,and possible biological function of PERVs.

Montezuma's revenge-the sequel: The one-hundred year anniversary of the first description of “post-infectious” irritable bowel syndrome

One-hundred years have passed since the original description of the commonly described phenomenon of persistent abdominal symptoms being triggered by an acute enteric infection. This first account was generated out of astute observations by Sir Arthur Hurst in World War I. Additional descriptions followed from military and non-military practitioners adding the evidence which has transitioned this recognized condition from association to causation. While mechanistic understanding is an area of active pursuit, this historical accounting of a centuries progress highlights important advances and contributions of military medicine and scientists to advances benefiting global populations.

Natural history of sensory nerve recovery after cutaneous nerve injury following foot and ankle surgery

Cutaneous nerve injury is the most common complication following foot and ankle surgery. However, clinical studies including long-term follow-up data after cutaneous nerve injury of the foot and ankle are lacking. In the current retrospective study, we analyzed the clinical data of 279 patients who underwent foot and ankle surgery. Subjects who suffered from apparent paresthesia in the cutaneous sensory nerve area after surgery were included in the study. Pa- tients received oral vitamin B^2 and methylcobalamin. We examined final follow-up data of 17 patients, including seven with sural nerve injury, five with superficial peroneal nerve injury, and five with plantar medial cutaneous nerve injury. We assessed nerve sensory function using the Medical Research Council Scale. Follow-up immediately, at 6 weeks, 3, 6 and 9 months, and 1 year after surgery demonstrated that sensory function was gradually restored in most patients within 6 months. However, recovery was slow at 9 months. There was no significant difference in sensory function between 9 months and 1 year after surgery. Painful neuromas occurred in four patients at 9 months to 1 year. The results demonstrated that the recovery of sensory func- tion in patients with various cutaneous nerve injuries after foot and ankle surgery required at least 6 months.

Enhanced history matching process by incorporation of saturation logs as model selection criteria

This paper proposes a methodology for an alternative history matching process enhanced by the incorporation of a simplified binary interpretation of reservoir saturation logs(RST) as objective function. Incorporating fluids saturation logs during the history matching phase unlocks the possibility to adjust or select models that better represent the near wellbore waterfront movement, which is particularly important for uncertainty mitigation during future well interference assessments in water driven reservoirs. For the purposes of this study, a semi-synthetic open-source reservoir model was used as base case to evaluate the proposed methodology. The reservoir model represents a water driven, highly heterogenous sandstone reservoir from Namorado field in Brazil. To effectively compare the proposed methodology against the conventional methods, a commercial reservoir simulator was used in combination with a state-of-the-art benchmarking workflow based on the Big LoopTMapproach. A well-known group of binary metrics were evaluated to be used as the objective function, and the Matthew correlation coefficient(MCC) has been proved to offer the best results when using binary data from water saturation logs. History matching results obtained with the proposed methodology allowed the selection of a more reliable group of reservoir models,especially for cases with high heterogeneity. The methodology also offers additional information and understanding of sweep behaviour behind the well casing at specific production zones, thus revealing full model potential to define new wells and reservoir development opportunities.

Envelope Functions of Time Histories in Seismic Safety Evaluation and Scenario Earthquakes

It has been a period of time since the concept of scenario earthquake was proposed, but this concept has rarely been used in seismic safety evaluation in China since then. Meanwhile, because of the uncertainties of magnitudes-distances pairs, there is large arbitrariness while determining the envelope function of time histories in seismic hazard analysis. In this paper, we describe a method to control the envelope functions of the time histories by introducing the most-likely combinations of magnitude and distance of the scenario earthquakes based on a probabilistic method, revise the software of the ellipse model for seismic hazard analysis, and give a computation example.

Century-Long History and Basic Experience of the CPC in Leading China’s Rural Development

Over the past century,the Communist Party of China(CPC)has led hundreds of millions of farmers through five stages(rural revolution,rural construction,rural reform,rural transformation and rural revitalization)to forge a road of rural development with Chinese characteristics.In the course of constant exploration and innovation,the CPC has always adhered to its original aspiration and founding mission of seeking happiness for the farmers,taken liberating and developing the productive forces as the central principle,regarded coordinating urban and rural development as the action guideline,and set“achieving common prosperity”as the target direction,and accumulated valuable historical experiences in three aspects:Firstly,the CPC has emphasized the vital role and pioneering spirit of farmers,effectively mobilizing and organizing the broad participation of rural masses.Secondly,it has committed to the collective ownership of rural land and managed the relationship between farmers and land.Lastly,the CPC has remained focused on the interests of farmers,continuously advancing reform and innovation in accordance with the changing times.

Sexual function history taking in medicine

＂Precedent＂ in the Narrative of Chinese Legal History

The traditional way of describing the history of Chinese law, i.e., fitting Chinese historical materials into the basic framework of the Western conceptual system needs to be thoroughly reconsidered. ＂Precedent＂ or ＂NJfftJ＂ （panli）, which has attracted academic attention both in China and abroad, can serve as an example in this regard. The concept ＇~N] fit],＂ which may have originated from Japanese kanji in the nineteenth century, was used to translate its Western counterpart. A review of the historical and modern practice of the Western European countries of England and France shows that precedent has always played an important role in achieving consensus in the legal community and guiding future rulings by means of case law. This function, which has something in common with the relevant portions of ancient Chinese legal institutions, can serve as a foundation for constructing a universal theoretical system. At the same time, the relevant Chinese institutions had specific institutional contexts and functions. By combining universal and specific functional analysis, ＂two-way functionalism＂ may be able to avoid the Western-centric approach and futile conceptual discrimination and turn towards the exploration and elucidation of functional issues, so as to eventually establish a new framework for the narrative of Chinese legal history.

一级学科视域下中共党史党建学理论的建设

作为一级学科,中共党史党建学要有源自并属于本学科的理论,中共党史党建学理论是必设的二级学科。搭建中共党史党建学理论自主的整体性框架,主要包括基本结构层面和功能运行层面。前者针对的是内部组成要素,涉及本体论、认识论和方法论;后者则针对研究过程中的边界与操作,从学理上将中共党史党建学理论研究同史学理论研究、政治学理论研究等相邻学科理论区分开来。作为独立的学科,中共党史党建学理论既不要理论依附、理论移植,也不要理论泛化,而是基于理论与实践通过有机联动、相互支撑、共同发展等手段而最终定型。中共党史党建学理论,不仅能够促进学科建设,更有利于服务中国共产党的治国理政。

Witness to History

A MILITARY band and 21-gun salute. That＇s the kind of fanfare nations use to announce a valued relationship with another nation. But when it comes to political parties, they prefer to make friends in a quieter way. Though the Communist Party of China （CPC）, one of the largest parties in the world with extensive relations with like- minded organizations around the world, turns 95 on July 1, there are few personal anecdotes on its exchanges with other parties.
