Nano-scale Reinforcements and Properties of Al-Si-Cu Alloy Processed by High-Pressure Torsion

To improve the comprehensive mechanical properties of Al-Si-Cu alloy,it was treated by a high-pressure torsion process,and the effect of the deformation degree on the microstructure and properties of the Al-Si-Cu alloy was studied.The results show that the reinforcements(β-Si andθ-CuAl_(2)phases)of the Al-Si-Cu alloy are dispersed in theα-Al matrix phase with finer phase size after the treatment.The processed samples exhibit grain sizes in the submicron or even nanometer range,which effectively improves the mechanical properties of the material.The hardness and strength of the deformed alloy are both significantly raised to 268 HV and 390.04 MPa by 10 turns HPT process,and the fracture morphology shows that the material gradually transits from brittle to plastic before and after deformation.The elements interdiffusion at the interface between the phases has also been effectively enhanced.In addition,it is found that the severe plastic deformation at room temperature induces a ternary eutectic reaction,resulting in the formation of ternary Al+Si+CuAl_(2)eutectic.

The Exorbitant Privilege of US Treasuries and China's Choices in the New Era

After the decoupling of the US dollar from gold in 1971,US Treasuries replaced gold as the value benchmark of the international monetary system and acquired an exorbitant privilege.Subsequently,the total amount of US debt exhibited an exponential expansion trend,unbound by any substantial constraints.The so-called debt ceiling is a partisan game rather than a rigid fiscal constraint on the United States.As long as there are no fundamental changes in the global monetary system,the international credit of US Treasuries will stay stable,and their trend of infinite expansion will be sustained.Massive quantitative easing policies have failed to significantly shake this stability,and the notion of global investors offloading US Treasuries is more an illusion than a fact.The exorbitant privilege of US Treasuries grants its federal government the“freedom to borrow,”shielding the American financial sector from due penalties during global financial crises and securing excessive returns in global capital cycles.In the old days when running“twin surpluses”on capital and current accounts,China kept the value of Renminbi low to support its export manufacturing sector along the southeast coast.As a result,China accumulated huge foreign exchange reserves,mainly US Treasuries.Nowadays,this practice is no longer necessary,yielding low returns and posing significant security risks.

New Developments in the Trumpification of the US Republican Party

The prominent performance of former US President Donald J.Trump in the 2024 presidential election cycle ref lects the ongoing developments of the Trumpification of the Republican Party(GOP).Since Trump left office,the Trumpification of the GOP has continued.In terms of ideological shaping,Trumpification is ref lected in the fact that the political stance of the GOP is dominated by Trump.In terms of personal influence,Trumpification is manifested by the overall acceptance of GOP elites and voters toward Trump's presidential candidacy,notwithstanding a decrease in their satisfaction with him.The recent developments in Trumpification are intricately linked to Trump's influence on the GOP's political ecology,such as the formation of a new GOP coalition and the reshaping of GOP elite composition.Additionally,these developments are also inf luenced by specific political factors,including the unique circumstances of the 2020 presidential election that led to Tr ump's“quasi-incumbent”status and the economic and immigration issues in the 2024 election that favor Trump.The role Trump plays in the 2024 election and its outcome will be critical in determining whether the inf luence of Trumpification,especially Trump himself,will persist or undergo changes.

Study on sex differences and potential clinical value of threedimensional computerized tomography pelvimetry in rectal cancer patients

BACKGROUND Laparoscopic rectal cancer radical surgery is a complex procedure affected by various factors.However,the existing literature lacks standardized parameters for the pelvic region and soft tissues,which hampers the establishment of consistent conclusions.AIM To comprehensively assess 16 pelvic and 7 soft tissue parameters through computerized tomography(CT)-based three-dimensional(3D)reconstruction,providing a strong theoretical basis to address challenges in laparoscopic rectal cancer radical surgery.METHODS We analyzed data from 218 patients who underwent radical laparoscopic surgery for rectal cancer,and utilized CT data for 3D pelvic reconstruction.Specific anatomical points were carefully marked and measured using advanced 3D modeling software.To analyze the pelvic and soft tissue parameters,we emp-loyed statistical methods including paired sample t-tests,Wilcoxon rank-sum tests,and correlation analysis.RESULTS The investigation highlighted significant sex disparities in 14 pelvic bone parameters and 3 soft tissue parameters.Males demonstrated larger measurements in pelvic depth and overall curvature,smaller measurements in pelvic width,a larger mesorectal fat area,and a larger anterior-posterior abdominal diameter.By contrast,females exhibited wider pelvises,shallower depth,smaller overall curvature,and an increased amount of subcutaneous fat tissue.However,there were no significant sex differences observed in certain parameters such as sacral curvature height,superior pubococcygeal diameter,rectal area,visceral fat area,waist circumference,and transverse abdominal diameter.CONCLUSION The reconstruction of 3D CT data enabled accurate pelvic measurements,revealing significant sex differences in both pelvic and soft tissue parameters.This study design offer potential in predicting surgical difficulties and creating personalized surgical plans for male rectal cancer patients with a potentially“difficult pelvis”,ultimately improving surgical outcomes.Further research and utilization of these parameters could lead to enhanced surgical methods and patient care in laparoscopic rectal cancer radical surgery.

Construction of a nomogram model to predict technical difficulty in performing laparoscopic sphincter-preserving radical resection for rectal cancer

BACKGROUND Colorectal surgeons are well aware that performing surgery for rectal cancer becomes more challenging in obese patients with narrow and deep pelvic cavities.Therefore,it is essential for colorectal surgeons to have a comprehensive understanding of pelvic structure prior to surgery and anticipate potential surgical difficulties.AIM To evaluate predictive parameters for technical challenges encountered during laparoscopic radical sphincter-preserving surgery for rectal cancer.METHODS We retrospectively gathered data from 162 consecutive patients who underwent laparoscopic radical sphincterpreserving surgery for rectal cancer.Three-dimensional reconstruction of pelvic bone and soft tissue parameters was conducted using computed tomography(CT)scans.Operative difficulty was categorized as either high or low,and multivariate logistic regression analysis was employed to identify predictors of operative difficulty,ultimately creating a nomogram.RESULTS Out of 162 patients,21(13.0%)were classified in the high surgical difficulty group,while 141(87.0%)were in the low surgical difficulty group.Multivariate logistic regression analysis showed that the surgical approach using laparoscopic intersphincteric dissection,intraoperative preventive ostomy,and the sacrococcygeal distance were independent risk factors for highly difficult laparoscopic radical sphincter-sparing surgery for rectal cancer(P<0.05).Conversely,the anterior-posterior diameter of pelvic inlet/sacrococcygeal distance was identified as a protective factor(P<0.05).A nomogram was subsequently constructed,demonstrating good predictive accuracy(C-index=0.834).CONCLUSION The surgical approach,intraoperative preventive ostomy,the sacrococcygeal distance,and the anterior-posterior diameter of pelvic inlet/sacrococcygeal distance could help to predict the difficulty of laparoscopic radical sphincter-preserving surgery.

Deformation characteristics of granitic rocks in Erguna ductile shear zone,NE China

The Erguna ductile shear zone is situated in the Erguna Massif,which has been exposed along the eastern bank of the Erguna River in northeastern China.The authors present comprehensive study results on the macro-and micro-structures,finite strain and kinematic vorticity,quartz electron backscatter diffraction(EBSD)fabrics,and geochronology of granitic rocks in the Erguna ductile shear zone.The deformed granitic rocks have experienced significant SE-trending dextral strike-slip shearing.Finite strain and kinematic vorticity in all deformed granitic rocks indicate that the deformation is characterized by simple sheardominated general shearing with S-L tectonites.Mineral deformation behaviors and quartz C-axis textures demonstrate that the deformed granitic rocks developed under greenschist to amphibolite facies conditions at deformation temperatures ranging from 450 to 550℃.New LA-ICP-MS zircon U-Pb ages indicate that these granitic rocks were formed in Early Triassic(~248.6 Ma)and Early Cretaceous(~136.7 Ma).All the evidence indicates that this deformation may have occurred in Early Cretaceous and was related to the compression resulting from the final closure of the Mongol-Okhotsk Ocean.

Reexamining Positivity of Thinking in Waiting for Godot Through Camus’s Absurdism

Absurdity originated from French existentialism,and Martin Esslin,in categorizing Waiting for Godot as a theater of the absurd,ignores the positive aspects of Camus’s absurdism and regards that as an existential tragedy of mankind.However,the author Samuel Beckett himself did not approve of such a definition,believing that Esslin’s definition of theater of the absurd was too judgmental and pessimistic.Through the imagery of boots,ropes,hats and baggage in Waiting for Godot,Beckett reveals the rootlessness,constraint and agony of the minds of people born into absurdity in the early 20th century.The luck of Lucky is Beckett’s use of irony:people who have lost the ability to think for themselves escape the absurdity and dystopia of life and descend to slaves.Gogo and Didi,who are waiting and expecting,and thinking in the midst of absurdity,represent“Godot”,the symbol of hope.Their endurance in waiting,akin to Camus’s Sisyphus,underscores a form of existential defiance that challenges the notion of absolute pessimism in absurdist literature.

The Drought of Amazonia in 2023-2024

The Amazon basin has experienced an extreme drought that started in the austral summer of 2022-23 and extends into 2024. This drought started earlier than other previous droughts. Although some rain fell during the austral summer, totals remained below average. Higher temperatures during austral winter and spring 2023, which affected most of Central South America, then aggravated drought conditions. This coincided with an intense El Niño and abnormally warm tropical North Atlantic Ocean temperatures since mid-2023. Decreased rainfall across the Amazon basin, negative anomalies in evapotranspiration (derived from latent heat) and soil moisture indicators, as well as increased temperatures during the dry-to-wet transition season, September-October-November (SON) 2023, combined to delay the onset of the wet season in the hydrological year 2023-24 by nearly two months and caused it to be uncharacteristically weak. SON 2023 registered a precipitation deficit of the order of 50 to 100 mm/month, and temperatures +3˚C higher than usual in Amazonia, leading to reduced evapotranspiration and soil moisture indicators. These processes, in turn, determined an exceptionally late onset and a lengthening of the dry season, affecting the 2023-2024 hydrological year. These changes were aggravated by a heat wave from June to December 2023. Drought-heat compound events and their consequences are the most critical natural threats to society. River levels reached record lows, or dried up completely, affecting Amazonian ecosystems. Increased risk of wildfires is another concern exacerbated by these conditions.

Research on English Translation of Chinese Literary Terms from the Perspective of International Communication: Interpretation and Standardization

Literary terms are the crystallization of Chinese ideology and wisdom. Translation and communication function as an important link in the construction of the discourse system with Chinese characteristics. Standardized translation of literary terms is an important way to help the world understand China and promote international communication of Chinese culture, which is conducive to the inheritance and interpretation of fine traditional Chinese culture. From the perspective of the "going global" strategy of Chinese culture in the new era, and the existing asymmetry of English translation of Chinese literary terms in international cultural communication, we analyzed the divergence, variation and imposed interpretation of the translations of Chinese literary terms and put forward some suggestions for their standardization. We believe that the translation of Chinese literary terms should adhere to the principle of "localization" in cultural communication and focus on the transmission of Chinese cultural connotation to correct the imposed interpretations of Chinese literature in the West. Standardizing the translations of literary terms will facilitate the communication of "Chinese knowledge" to the world. The paper is expected to provide reference for research on construction and enhancement of discourse system for global communication with Chinese characteristics.

History of the PRC’s Participation in International Human Rights Affairs and Its Contribution to the Cause of International Human Rights

The history of the participation of People’s republic of china in international human rights affairs can be mainly divided into two phases since its founding 70 years ago,and it can be further divided into four stages with typical events after the launch of reform and opening-up.Since the adoption and implementation of the reform and opening-up policy in the late 1970 s china has witnessed the active participation and fruitful achievements of china in bilateral and multilateral human rights cooperation and communication,as well as making important contributions to the international human rights cause.

The Relationship Between Anti-terrorism and Human Rights Protection: Perspective of International Politics

This article briefly outlines how anti-terrorism struggles became linked and their relationship thereafter with human rights issues in international political life. With equal relevance and value to human development, anti-terrorism efforts and human rights protection are themselves not mutually exclusive or contradictory. Their conflict in everyday life has sometimes resulted from the fact that they are both manipulated in the service of certain political ends. What's more, there has never been p erfect human rights protection in the world so far, which often makes human rights problems an easy charge against almost every government. No anti-terrorist activities in either the US or Europe have been really constrained by the idea of human rights no matter how beautiful their rhetoric has been. Now both human rights and anti-terrorism have been made into a tool of diplomacy and international politics. With the war in Afghanistan over, the United States is enhancing its human rights diplomacy together with its anti-terrorism diplomacy. Truly efficient, comprehensive international cooperation on anti-terrorism is still far away.

The Main Characteristics of China’s International Human Rights Cooperation and Exchanges from 2010 to 2020

An Analysis of Gender Binarism in McCullers’The Heart Is a Lonely Hunter

This paper provides an analysis of gender binarism in Carson McCullers’novel,The Heart Is a Lonely Hunter,situated within the socio-cultural milieu of Southern America.It examines the depiction of persisting challenges posed by binary gender paradigms and the portrayal of potential emancipation within the narrative.The analysis focuses on two central characters,interpreting them as contrasting cases.One character represents the paradox inherent in the rebellious endeavors,highlighting how these actions,influenced by Phallocentrism and a broader framework of hierarchical structures,might inadvertently reinforce gender binarism.The other character exemplifies a triumphant departure from the binary gender paradigm through striving to attain a state of equilibrium marked by the harmonious coexistence of gender differences.Through this analysis,the paper reveals the author’s dual perspectives in her exploration of gender binarism using these two distinct protagonists.At last,it employs the traditional Chinese philosophical concept of“harmony in diversity”in conjunction with feminist and gender theories to elucidate the encouraged path toward emancipation from gender binarism within McCullers’narrative.

The Writing of Body in The House of Mirth

Historical studies on the character of Lily Bart in Edith Wharton’s The House of Mirth have predominantly revolved around psychology,sociology,and aesthetics,yet neglecting the significance and role of the body within the narrative.Using Brooks’s concept of body writing,this paper focuses on exploring Lily’s body in three dimensions:the body of vision(self-objectification);the body of privacy(moral dilemma);and the body of modernity(overdose symbolizing the clash of science and humanity).Scrutinizing and analyzing the body writing in The House of Mirth reveal the feminist undercurrents of Lily’s character and highlight the broader and significant role of body writing in literary works.
