Spatiotemporal Evolution of Ecological Quality in Alpine Freshwater Lake Nature Reserves in the Past 20 Years

The Caohai Nature Reserve is one of the three major plateau freshwater lakes in China.Since the 1950s,human activities such as land reclamation and population relocation have greatly damaged Caohai.A rapid evaluation of the spatiotemporal evolution trend of the ecological quality of the Caohai Nature Reserve is significant for the maintenance and construction of the ecosystem in this area.The research is based on the Google Earth Engine(GEE)remote sensing cloud computing platform.Landsat TM/OLI images from May to October in five time periods:2000-2002,2004-2006,2009-2011,2014-2016,and 2019-2021 were obtained to reconstruct the optimal cloud image set by averaging the images in each time period.By constructing four ecological indicators:Greenness(NDVI),Wetness(Wet),Hotness(LST),and Dryness(NDBSI),and using Principal Component Analysis(PCA)method to obtain the Remote Sensing Ecological Index(RSEI)for the corresponding years,the spatiotemporal variation of ecological quality in the Caohai Nature Reserve over 20 years was analyzed.The results indicate:①the mean value of RSEI increased from 0.460 in 2000-2002 to 0.772 in 2019-2021,a 67.83%increase,indicating a significant improvement in the ecological quality of the reserve over the 20 years;②from the perspective of functional zoning of the Caohai Nature Reserve,the ecological quality of the core area showed a degrading trend,while the ecological quality of the buffer zone and experimental zone significantly improved;③with the implementation of ecological restoration projects,the ecological quality of the reserve gradually recovered and improved from 2014 to 2021.The trend of RSEI value changes is well correlated with human interventions,indicating that the PCA-based RSEI model can be effectively used for ecological quality assessment in lake areas.

“Eternal Motion” as a “Form of Movement of a Special Nature” and the Main Condition for the Creation of the Universe

The article hypothesizes that DE and DM (UCM) are a “Form of Motion of a Special Nature”, where “Form of Motion” means “Eternal Motion” as the power of dynamics of different levels and varying degrees of self-sufficiency, and by “Special Nature”, gravitational and two other properties of matter, “tied” to the “Eternal Movement” and completely dependent on it. Carriers of key properties of a “Special Nature” have been established: “0”-DE particles and “3”-DM particles (UDM). The unity of their inherent “motionally-gravitational” properties and the peculiarity of the relationship between “motion” and “gravity” are revealed: the higher the intensity of “Eternal Motion”, the stronger the gravitational properties of matter are manifested (and vice versa). The relationship of “time” with the “vibration frequency” and the “mass” of photons with the “degree of bonding and deformation properties of the field” is shown. The maximum level of gravity has been determined, which allows Nature to successfully create the Universe: such a landmark is the proximity to the property of the Primary Source—the “pure graviton” of the OSP space, the most powerful “motionally-gravitational” particle of the Universe. The reasons for the emergence of such an identity of the gravitational properties of particles with the indicators of a “pure graviton” are established: for “0”-DE particles, this is the acquisition of the function of “freedom of movement”;for “3”-DM particles (UDM), the creation of a special structure—a “double field” (“Main” and “Small”). The presence in the “double field” of specific “tools” for the creation of the worlds of the Universe—gravitational “waves” gives rise to impulses (shocks) of varying intensity and shape. A list of functions performed by “waves” in the “Main” and “Small” fields has been compiled. The specific conditions for the formation of “UDM Streams”, their transformation into a “Vortex” and, under the influence of a powerful Initial Impulse (push), sending them to the “place” of the creation of galaxies, are shown. It is suggested that there is a “Cycle of Matter in Nature” in the closed structure of our Universe due to the “work” of “waves” and the functioning of special “factories” in the form of exotic space objects—Black holes.

The Alienation of Nature in Emily Dickinson’s Poems through the Prism of Taoism

In the poems created by the renowned American poet Emily Dickinson,those related to nature constitute a considerable proportion.However,Dickinson’s attitude toward nature is,in fact,contradictory.On the one hand,Dickinson perceives nature as gentle and kind,akin to a mother.Nature is regarded as“heaven”and embodies harmony.On the other hand,nature possesses its own operational principles and harbors inherent cruelty.According to Dickinson,humans should refrain from excessive interference in the natural order.This article attempts to analyze the similarities in attitude towards nature between Dickinson’s poetry and Taoist philosophy.

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.

Development and validation of an online calculator to predict the pathological nature of colorectal tumors

BACKGROUND No single endoscopic feature can reliably predict the pathological nature of colorectal tumors(CRTs).AIM To establish and validate a simple online calculator to predict the pathological nature of CRTs based on white-light endoscopy.METHODS This was a single-center study.During the identification stage,530 consecutive patients with CRTs were enrolled from January 2015 to December 2021 as the derivation group.Logistic regression analysis was performed.A novel online calculator to predict the pathological nature of CRTs based on white-light images was established and verified internally.During the validation stage,two series of 110 images obtained using white-light endoscopy were distributed to 10 endoscopists[five highly experienced endoscopists and five less experienced endoscopists(LEEs)]for external validation before and after systematic training.RESULTS A total of 750 patients were included,with an average age of 63.6±10.4 years.Early colorectal cancer(ECRC)was detected in 351(46.8%)patients.Tumor size,left semicolon site,rectal site,acanthosis,depression and an uneven surface were independent risk factors for ECRC.The C-index of the ECRC calculator prediction model was 0.906(P=0.225,Hosmer-Lemeshow test).For the LEEs,significant improvement was made in the sensitivity,specificity and accuracy(57.6%vs 75.5%;72.3%vs 82.4%;64.2%vs 80.2%;P<0.05),respectively,after training with the ECRC online calculator prediction model.CONCLUSION A novel online calculator including tumor size,location,acanthosis,depression,and uneven surface can accurately predict the pathological nature of ECRC.

Beyond Morality:Han Fei’s Unconventional Insights Into Human Nature

Han Fei presented a thought-provoking perspective on human nature and its implications for governance.Departing from traditional moral doctrines,Han Fei’s“non-moralistic”philosophy posited that human nature is inherently self-interested and driven by personal gain.In this paper,we explore Han Fei’s keen insights into human nature and its practical application in political governance.His emphasis on aligning political strategies with human inclinations,rather than relying solely on moral preaching,highlights the complexity and pragmatism of his approach.However,we also examine the limitations of his philosophy,particularly in disregarding individual differences and idealism.By striking a balance between political expediency and moral considerations,Han Fei’s ideas continue to resonate with contemporary discussions on governance and human behavior.This study calls for a reflective and cautious assessment of the implications of Han Fei’s“non-moralistic”thought in today’s society.

Human Rights Connotations and Its Legal Protection in the Harmonious Coexistence between Humans and Nature

Promoting the unity of human nature and sociality in practice is a fundamental path dependence for achieving people's well-rounded development.Within the context of harmonious coexistence between humans and nature,the practice of the unity of human nature and sociality is allowed to be truly implemented,and people's well-rounded development moves from possibility to reality.Strengthening the protection of human rights for people's well-rounded development in the harmonious coexistence between humans and nature not only requires the expansion of the connotations of environmental rights from“the right to a healthy environment”to“the right to a beautiful environment”,but also necessitates the formation of a collaborative framework between environmental rights and development rights.For legal responses to the expansion of the connotations of environmental rights,it is necessary to implement such expansions in environmental legislation,enhance the underlying principles,and make progress in the development of systematic environmental legislation simultaneously.Regarding the legal promotion of the synergy between environmental rights and development rights,it is essential to follow the guidance of the“Two Mountains Theory,”take the coordinated functions of environmental and traditional legal departments as the basis,and build a legal mechanism for the realization of the value of ecological products and services.

On the Possible Cometary Nature of the Uchur Cosmic Body(Fall 3.08.1993)

An expeditionary study of the area of the alleged impact event that occurred on 3.08.1993 in the area of the Lower Konkuli River(southeast of the Aldan Highlands,Lurikan Range,Russia)was carried out.According to the materials of remote sensing,the places of collision with the earth of a cosmic body are determined.In the area of the impact of the shock wave on the Earth’s surface,peat samples were selected,the micro probe analysis of which showed the pres­ence of a cosmogenic substance in concentrations 6-8 times higher than the background.Silicate and magnetite micro spheres,native iron,moissanite,and carbon micro tubes coated with a film consisting of pure nickel were found.Of particular interest were the findings of specific Ni film micro structures that allow us to make an assumption about the cometary nature of the Uchur cosmic body.Most researchers associate the observed flights of fireballs with the sub­sequent fall of meteorites.Researchers are trying to find the massive body of the fallen space body.However,often,even after many years of searching,a massive cosmic body cannot be found.This happened when studying the site of the fall of the Tunguska cosmic body.In this case,it remains to be assumed that the cosmic body contained micro­scopic dust particles.The structure and composition of such particles can only be studied using microscopic research methods.When studying the Uchur cosmic body,the authors concluded that it could be of a cometary nature due to the findings of specific particles-thin films of pure nickel on the surface of plant remains of terrestrial origin.This hy­pothesis arose from the recent discovery of atomic nickel vapors in comets.

Contribution and Modern Public Debt:On the Nature of Patriotic Public Debt in the Late Qing Dynasty and the Early Republic of China

There are different opinions about the first modern domestic debt in China.The theorists judge whether a certain public debt has modernity according to whether it has modern public debt form,ignoring the inconsistency between form and content,institutional provisions and actual implementation.The modern nature of public debt must have both the form and content of modern public debt.Based on the analysis of the issuing background,system design,collection and repayment of patriotic bonds in the late Qing Dynasty and the early Republic of China,it is considered that the part of patriotic bonds subscribed by the Qing royal family is still the nature of donation and return,while the part subscribed by ordinary businessmen and people in the early Republic of China has a modern nature.The dual nature of patriotic bonds is closely related to the social background when the bonds are issued.

Eternal Nature: Spiritual Haven——The Function of Nature in Rip Van Winkle

Rip Van Winkle is one of the most enduring stories of Washington Irving. It is a fantasy tale about a man who somehow "stepped outside of the mainstream of life" (Chang Yao-xin, 1991: 62). Rip Van Winkle lived in a village near the Hudson River north of New York City. He was a simple, good-natured man; he was, moreover, a kind neighbor and an obedient hen-pecked husband. Yet Rip was lazy and this kept him in constant trouble with his wife. His two favorite past-times were sitting in front of the inn, chatting with his friends, and wandering through the mountains with his dog, Wolf. On one of these trips he met a strange dwarf who invited him to join him and other strange-looking dwarfs in a drinking party and a game called nine-pins, in a remote valley. Rip drank too much of beverage and fell asleep. When he woke up, he found that during just one night, twenty years had vanished and strangers were everywhere. His scolding wife had died, and his son, every bit his counterpart in appearance and personality had grown up to replace him. At last he was reunited with a married daughter and began to live a life the same as before.

The Man Who Organized Nature: The Life of Linnaeus by Gunnar Broberg

GunnarBroberg(1942–2022),a professor of history ideas and sciences at the Lund University in Sweden,has assembled and summarized virtually all of the contemporary documents relating to the life of Carl Linnaeus(1707–1778).This is therefore a fact-laden and definitive personal biography of the founder of our systems of plant and animal taxonomy.Linnaeus’childhood included much time in nature that forever provided him an experience background for the huge amount of plant and animal species he would encounter.In his early days,his country was in an era of poverty where“hordes of starving,homeless people drifted along the roads in the years when the harvest failed.”Linnaeus himself“...could lie awake all night as he lacked the money for evening meals when he was a student.”He inserted paper into his shoes to cover the holes on which he walked.

On Reserves of Hippophae rhamnoides L. Fruit on the Territory of the Zarafshan National Nature Park of Uzbekistan
