Genetic diversity of the msp-1,msp-2,and glurp genes of Plasmodium falciparum isolates along the Thai-Myanmar borders

Objective:To study the genetic diversity at the msp—1,msp—2,and glurp genes of Plasmodium falciparum(P.falciparum) isolates from 3 endemic areas in Thailand:Tak.Kanchanaburi and Ranong provinces.Methods:A total of 144 P.falciparum isolates collected prior to Irealmenl during January.2012 to June,2013 were genotyped.DNA was extracted:allele frequency and diversity of msp-1.msp-2,and glurp genes were investigated by nested polymerase chain reaction.Results:P.falciparum isolates in this study had high rate of multiple genotypes infection(96.5%)with an overall mean multiplicity of infection of 3.21.The distribution of allelic families of msp-1was significantly different among isolales from Tak.kanchanahnri.and Ranong but not for the msp-2.K1 and MAD20 were the predominant allelic families at the msp-1 gene,whereas alleles belonging to 3D7 were more frequent at the msp-2 gene.The glurp gene had the least diverse alleles.Population structure of P.falciparum isolates from Tak and Ranong was quite similar as revealed by the presence of similar proportions of MAD20 and K1 alleles at msp-1 loci.3D7 and FC27 alleles at msp-2 loci as well as comparable mean MOI.Isolates from Kanchanaburi had different structures;the most prevalent alleles were K1 and RO33.Conclusions:The present study shows that P.falciparum isolates from Tak and Ranong provinces had similar allelic pattern of msp—1 and msp—2 and diversity but different from Kanchanaburi isolates.These allelic variant profiles are valuable baseline data for future epidemiological study of malaria transmission and for continued monitoring of polymorphisms associated with antimalarial drug resistance in these areas.

Control Effect of Slow-release, Long-acting and Multi-functional New Pesticides on Sugarcane Borders and Woolly Aphids

In order to select the long-acting,low toxic,low-risk and multi-functional new pesticides for the control of sugarcane borders and woolly aphids and precise and efficient application technology,the control effect of 10% monosultap · thiamethoxam granular formulation and 1% Bt · clothianidin granular formulation on sugarcane borders and woolly aphids were studied.The results showed that 10% monosultap·thiamethoxam GR and 1% Bt·clothianidin GR had good control effects on sugarcane borders and woolly aphids.They were ideal slow-release,long-acting,low toxic and multi-functional new pesticides used to control sugarcane borders and woolly aphids.They could be used alternately with other pesticides to delay the emergence and development of pest resistance to pesticides.The best dosage of the two pesticides in the field was 45 kg/hm^2.They could be mixed with fertilizer( 1200-1800 kg/hm^2),scattered in sugarcane ditches or at the base of sugarcane plants,and covered with soil or film from January to July.The control effect on dead heart seedlings damaged by borers could be up to above 79.2%,and the control effect on sugarcane woolly aphids could reach more than 98.8%.In comparison with the control group,the actual yield and sugar content of sugarcane increased by above 41 555 kg/hm^2 and 6.5% respectively.The application of slow-release,long-acting,strong systemic and multi-functional new agents with fertilizer around roots is convenient,precise and efficient,labor-saving,time-saving and environmentally friendly,and is worthy of being widely applied in sugarcane areas.

How Waterways, Glacial Melt Waters, and Earthquakes Re-aligned Ancient Rivers and Changed Illinois Borders

The borders of Illinois were established when Illinois became a state in 1818. The western border was delineated using the Mississippi River, and the Ohio River was used as the southern border. The eastern border was formed by the Ohio and Wabash Rivers plus the line along latitude 42030＇30＇＇ connecting the Wabash River to Lake Michigan. As initially proposed, the northern border of Illinois would have been 82 km （51 mi） to the south of the current longitude line of 87~31 ＇. This 2,160,000 ha （5,440,000 ac） addition to Illinois resulted in the territory having the required minimum of 40,000 people to qualify as a state. The northern border was moved to allow the linkage of the Great Lakes shipping route to the Illinois and Mississippi River navigation channels. Illinois thus gained a valuable shoreline on Lake Michigan and a location for a shipping port hub which became Chicago. Initially the transfer of goods between these waterways required a portage, but later a shipping canal was created to link the waterways. During the Civil War, Union forces used the connected waterway systems as a northern supply route to avoid the contested Ohio River.

Crossing Borders: Negotiation of Dual Cultural Identity of Chinese American in Pangs of Love

David Wong Louie demonstrates the emotional pangs between the immigrant parent Mrs. Pang and her Americanized children in Pangs of Love. Through examining the source of the pangs, this paper argues that characters'pangs mainly stem from confrontations between their different cultural identities. Focusing on the way of dealing with conflicts of cultural identities in contemporary Chinese American families, this paper illuminates that Chinese Americans need to cross cultural borders and negotiate cultural identity between Chinese and American cultures under the circumstance of globalization.

Cardiology without borders

Cardiovascular disease takes place in a border-free world. The challenge at the American College of Cardiology (ACC) and anywhere else in the world is to hold patient care above the artificial barriers raised by geopolitical issues. Fundamentally, the goal of ACC members or of any cardiology societies in the world is to provide excellent patient care. Cardiovascular disease is essentially the same throughout the world. Where there are minor variations among individuals, as clinicians we find priceless opportunity to learn. Expanding- rather contracting -our experience base helps us as individuals to realize our best potential as practitioners.

Geographical Factor as a Basis for Research of State BordersmAn Example of Georgia

The work deals with analysis of geographical factor as one of the main factor determining the historical change of a border on the example of Georgia. The research was conducted in two main directions： the evaluation of historical transformations of state borders of Georgia throughout of XIX-XX centuries and identification the leading geographical factors. Special emphasis has been made on geographical and cartometric analysis of modern state border of Georgia. In order to identify the historical transformations of state border that have used different methods as well as GIS-technologies, the research is based on the historical, cartographical and statistical data. On the base of a lot of cartographic sources, it is concluded that the borderline in modem topographic maps is often plotted by ignoring the international practice related to plotting the state borders across the physical-geographical objects. This is why the geographical factor seems important in the historical transformations of the state border creating similarly a negative perspective in the future. The main results of research are： （1） classification of geographical factors causing the transformations of the state borders; （2） Evaluation of sensitivity of state border; and （3） creation of DB of the state border of Georgia, allowing continuing the studies in the future.

CHINA demonstrated its resolve to expand its opening-up to the world when China’s Ministry of Commerce and the Shandong Provincial People’s Government jointly held the first Qingdao Multinationals Summit on October 19.During the summit,the report Multinationals in China:40 Years of Investment was released.According to the report,from 1978 to 2018,China’s actual use of foreign direct investment(FDI)amounted to US$2.1 trillion,making the country one of the Opportunities created by the Chinese market and multinationals go beyond borders to benefit the world world’s largest destinations for FDI.In 2018 alone,China absorbed a total of US$134.97 billion of FDI,ranking second in the world.This huge amount of foreign investment represents the world’s confidence in China’s economy and presents the world a historic opportunity to share the achievements brought about by China’s development.

The Dialectic of Borders and Multiculturalism in Naomi Nye＇s Habibi

This paper investigates how the Arab-American writer Naomi Nye addresses the dialectic between borders and multiculturalism in her award-winning young adult novel Habibi （1997）. Critiquing the essentialist view that presumes fixed boundaries for a culture, Nye promotes the alternative view that assumes individuals＇ power of defining and redefining their cultural identities in a multicultural society. The author argues that Nye＇s position is that borders/boundaries and geographical demarcations are flimsy, arbitrary and create divisions, animosities and hatred between people and nations whereas multiculturalism engenders feelings of reconciliation, friendship, and understanding. Though borders and boundaries can be divisive, cultural variety and hybridity can be inclusive. To counteract the argument of borders/boundaries, Nye posits the argument of multiculturalism. In this paper, the author intends to examine the assumptions of the physical and the cultural borders rhetoric in comparison with the multicultural approach narrative. It is the dialectic of these two opposing forces that shapes the events and the final outcome of the action and events of this novel

Border Sensitive Knowledge Distillation for Rice Panicle Detection in UAV Images

Research on panicle detection is one of the most important aspects of paddy phenotypic analysis.A phenotyping method that uses unmanned aerial vehicles can be an excellent alternative to field-based methods.Nevertheless,it entails many other challenges,including different illuminations,panicle sizes,shape distortions,partial occlusions,and complex backgrounds.Object detection algorithms are directly affected by these factors.This work proposes a model for detecting panicles called Border Sensitive Knowledge Distillation(BSKD).It is designed to prioritize the preservation of knowledge in border areas through the use of feature distillation.Our feature-based knowledge distillation method allows us to compress the model without sacrificing its effectiveness.An imitation mask is used to distinguish panicle-related foreground features from irrelevant background features.A significant improvement in Unmanned Aerial Vehicle(UAV)images is achieved when students imitate the teacher’s features.On the UAV rice imagery dataset,the proposed BSKD model shows superior performance with 76.3%mAP,88.3%precision,90.1%recall and 92.6%F1 score.

Specialization or Diversification:Which is More Conducive to Foreign Trade Resilience?Evidence from China-Russia Border Regions in Northeast China

Under the background of complex international situation,how to build the special geo-economic space of China-Russia bor-der lies in strengthening their foreign trade resilience against external shocks.Based on empirical evidence from ten prefecture-level China-Russia border regions in Northeast China,this paper analyzed the spatiotemporal evolution of foreign trade resilience under different shocks.Furthermore,through the Panel Regression model,the mechanism of the industrial structure on the foreign trade resilience in contraction period and expansion period was discussed.The results showed that:1)from 2004 to 2021,foreign trade in China-Russia border regions experienced five phases.The overall foreign trade resilience was higher than expected,showing a rising volatility trend,but there was significant spatial heterogeneity in the ability of cities to cope with shocks.2)Highly specialized clusters were mainly concentrated in Yichun,Heihe and Da Hinggan Ling Prefecture,while Mudanjiang and Yanbian performed better in related and unrelated diversification.3)In different stages of economic system evolution,the response mode,degree and result of border foreign trade resilience to regional industrial structure showed obvious stage characteristics.During the contraction period,related diversification was more conducive to improving the resistance through risk spillovers.During the expansion period,specialization played a more significant role in improving regional resilience through self-reinforcing effect.These results are beneficial for expanding the resilience theory,ensuring border economic security and optimizing border industrial investment layout.
