First, in reporting their physical and emotional struggles with cancer as the most difficult time of their lives, participants described feeling alone as they navigated treatment side effects and continued fear of cancer.

The migrant and seasonal farmworker toiling in the fields and orchards of the United States of America surmounts innumerable problems daily. Some of these problems pertain to the overall health of the farmworker in addition to the various occupational hazards that he or she faces. This research paper focuses on Tuberculosis infection—both latent and active—in the migrant farmworkers in the United States with a special focus on the US-Mexico border. Using the Socio-Ecological Model as a theoretical framework, the TB health issues faced by this group are studied. The various determinants of health at every level of the Socio-Ecological Model are cogitated upon and culturally appropriate interventions are suggested. This research paper corroborates the fact that health issues facing mobile communities like migrant farmworkers require a synergistic approach by various stakeholders spanning the length and breadth of the Americas. 展开更多

Introduction: Studying the use of psychoactive substances in completed suicide is essential in order to understand its role in the suicide generating stimuli. The most commonly reported substances are alcohol and opioids. Method: This is a retrospective study of completed suicide database of the Forensics Medical office in the city of Mexicali from 1999 to 2005. This is the capital of the Mexican state of Baja California in the US-Mexico border region. Results: Out of 288 suicides, 260 were men, and the most frequent drug found on autopsy was methamphetamine (p < 0.001). The modal victim was a young male (20 - 39 years old), employed in blue-collar jobs, lived in an urban area, found in their homes, and died by hanging. Discussion: Although no causal effect can be drawn, our study results suggest that methamphetamine use may be a risk factor for suicide in this sample. 展开更多

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. 展开更多

Objectives:To describe and compare the incidence,stage at diagnosis,and survival for genitourinary cancers in the border regions and in Hispanic-Americans.Materials and methods:A population-based search was performed using the Surveillance,Epidemiology,and End Results Program 18 database and the Texas Cancer Registry from 2000 to 2017.Cox regression models were performed with adjusted for age,gender,race,cancer type,cancer stage,insurance status,and cause of death were used to compare cancer-specific survival.Results:A total of 63,236 kidney and renal pelvis,38,398 bladder,170,640 prostate,24,313 testicular cancer cases were identified.Cancer-specific survivalwas found to beimproved in Hispanic-Americans in kidney and renal pelvis(hazard ratio[HR],0.903,95%confidence interval[CI],0.856-0.952,p=0.0001),and bladder cancers(HR,0.817,95%CI,0.743-0.898,p<0.001),despite a more advanced stage at diagnosis in Hispanics with bladder cancer(p<0.0074).Testicular cancer has a survival disadvantage for individuals living in the border region(HR,1.315,95%CI,1.124-1.539,p=0.0006).Conclusions:Disparities exist between Hispanic-Americans and Non-Hispanic White and also between individuals living in the border counties when compared to other regions.This is most significant in individuals with testicular cancer residing in the border region who demonstrate worse overall survival. 展开更多

In-depth research was conducted on the types,seasonal patterns,spatial levels,overwintering,summering,drought resistance,and disease and pest resistance of ornamental grasses in the road flower borders of Hefei,Anhui Province.Through field investigations,a total of 36 ornamental grasses were identified,with Liliaceae having the most species and the Lamiaceae the least.The results show that there are more warm season ornamental grasses,of 23 species;Acorus gramineus and Melinis minutiflora have poor overwintering ability;Arrhenatherum elatius,Festuca glauca,and Stipa tenuissima have poor summer tolerance;most ornamental grasses have strong drought resistance and resistance to pests and diseases.The comprehensive investigation shows that ornamental grasses have good application prospects and adaptability in the road flower borders in Hefei city. 展开更多

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. 展开更多

An analytic hierarchy process(AHP)was employed to establish a landscape value evaluation model for 20 common species of perennial flowers in the flower border of Hefei City.With the overarching objective of determining the application value of the flower border,10 evaluation factors were identified and subsequently classified into 3 distinct grades.Grade I(L>2.5)was defined as perennial flower resources with the highest development and utilization value,including only one species of Salvia farinacea.Grade II(2.0≤L≤2.5)was defined as perennial flower varieties suitable for most areas,encompassing 9 species of plants,such asTaraxacummongolicum.Grade III(L<2.0)was defined as perennial flower varieties with low application value,encompassing 10 species of plants,such asRuellia brittoniana,but lacking the value of further popularization and application.Consequently,the proportion of their application in the flower border should be reduced.The evaluation results can serve as a theoretical foundation for the implementation of perennial flowers in urban flower borders. 展开更多
