The accuracy of monsoon seasonal predictions significantly impacts the lives of billions who depend on or are affected by monsoons, as it is essential for the water cycle, food security, ecology, disaster prevention, and the economy of monsoon regions. Given the extensive literature on Asian monsoon climate prediction, we limit our focus to reviewing the seasonal prediction and predictability of the Asian Summer Monsoon (ASM). However, much of this review is also relevant to monsoon predictions in other seasons and regions. Over the past two decades, considerable progress has been made in the seasonal forecasting of the ASM, driven by an enhanced understanding of the sources of predictability and the dynamics of seasonal variability, along with advanced development in sophisticated models and technologies. This review centers on advances in understanding the physical foundation for monsoon climate prediction (section 2), significant findings and insights into the primary and regional sources of predictability arising from feedback processes among various climate components (sections 3 and 4), the effects of global warming and external forcings on predictability (section 5), developments in seasonal prediction models and techniques (section 6), the challenges and limitations of monsoon climate prediction (section 7), and emerging research trends with suggestions for future directions (section 8). We hope this review will stimulate creative activities to enhance monsoon climate prediction.展开更多

文摘The Asian Houbara(Chlamydotis macqueenii),a vulnerable species,is under significant threat from habitat degradation and anthropogenic pressures in Pakistan's arid landscapes.This study addresses the urgent need for conservation by identifying critical habitats,analyzing the influence of environmental and human factors on species distribution,and projecting future habitat shifts under climate change scenarios.Using the Max Ent model,which achieves a robust predictive accuracy(AUC=0.854),we mapped current and future habitat suitability under Shared Socioeconomic Pathways(SSP126,SSP370,SSP585)for the years 2040 and 2070.Presently,the suitable habitat extends over 217,082 km^(2),with 52,751 km^(2) classified as highly suitable.Key environmental drivers,identified via the Jackknife test,revealed that annual mean temperature(Bio1)and slope play a dominant role in determining habitat suitability.Projections show significant habitat degradation;however,under SSP585,highly suitable areas are expected to expand by up to 24.92%by 2070.Despite this increase,vast areas remain unsuitable,posing serious risks to population sustainability.Moreover,only 2115 km^(2) of highly suitable habitat currently falls within protected zones,highlighting a critical conservation shortfall.These findings highlight the imperative for immediate,targeted conservation efforts to secure the species'future in Pakistan's desert ecosystems.
文摘BACKGROUND Cardiac arrest is a critical condition characterized by abrupt cessation of cardiac function,resulting in reduced oxygen delivery to vital organs and rapid progression to death if not timely treated.Despite advances in medical science and resuscitation techniques,cardiac arrest remains a significant burden globally,with survival rates remaining low.Comprehensive research on cardiac arrest,particularly comparisons between in-hospital cardiac arrest(IHCA)and out-of-hospital cardiac arrest(OHCA),is limited.AIM To compare the survival rates,return of spontaneous circulation(ROSC),survival to discharge,and neurological outcomes after IHCA and OHCA in Arab Asian countries.METHODS We systematically searched PubMed,Medline,EMBASE and Google Scholar(2000-2024)using keywords(“IHCA”,“OHCA”,“cardiac arrest”,“Middle East”,“Arab”,“Asian”)in titles/abstracts.The inclusion criterion was observational studies on adults(≥18 years)in Arab Asian countries reporting relevant outcomes.The exclusion criteria were narrative reviews,non-Arab Asian studies,non-English publications,inaccessible full texts,pediatric-only populations,and studies lacking outcome data.RESULTS In total,44 observational studies from nine Arab Asian countries comprising 32535 participants were included.This review highlights the substantial variability in cardiac arrest outcomes in Asian countries.OHCA mortality rates were alarmingly high in several nations,with Kuwait(99%),Bahrain(98.8%),and Qatar(97.6%)reporting the highest figures.In contrast,the Kingdom of Saudi Arabia(KSA)had a markedly lower OHCA mortality rate(8.2%).The rates of ROSC also varied,with Qatar achieving the highest(34.4%)and Kuwait the lowest(3.3%).Survival to hospital discharge ranged from 1.2%in Bahrain to 18.7%in Kuwait,with Qatar also reporting favorable rates(17.5%).For IHCA,mortality was 73.6%in the United Arab Emirates(UAE)and 72.8%in KSA,whereas Lebanon and Iraq reported higher rates of 94.6%and 88%,respectively.ROSC rates were the highest in Lebanon(55.9%)and the UAE(51.3%).Neurological outcome reporting has been inconsistent,although Qatar reported a high rate(68.6%)for OHCA survivors.Comparative data showed generally better survival and neurological outcomes with IHCA than with OHCA.CONCLUSION This systematic review underscores the clear disparity in survival outcomes between IHCA and OHCA in Arab Asian countries,with IHCA demonstrating superior outcomes.Despite progress in some countries,outcomes remain suboptimal compared with international standards.Future multicenter studies with standardized methodologies are required to generate high-quality evidence and provide region-specific interventions for cardiac arrest management.

文摘East Asian continental tectonics challenges the plate tectonics paradigm with its diffuse intraplate deformation,magmatism,and earthquakes.Despite extensive studies,fundamental questions persist.This review examines ten critical questions of East Asian tectonics,including the thickness of the continental lithosphere,the origin of the North–South Gravity Lineament,and the northern extent of the Indian plate beneath the Tibetan Plateau.Additional questions address the Tibetan Plateau's lateral growth,the Tianshan mountain building,the mantle flow in response to the Indo-Asian collision,and the formation of the Shanxi Rift.The review also explores the subduction along the eastern margins of the East Asian Continent and the origins of the Changbaishan volcanic field,the destruction of the North China Craton,and the development of the Mesozoic Large Granitic Province in South China.Originally presented at the DEEP2024 workshop to stimulate discussion of how SinoProbe-II research initiatives could advance our understanding of Asian tectonics,this review provides context for each question,summarizes current knowledge,and identifies promising research directions.

文摘Acral melanoma,the most common melanoma subtype in East Asia,is associated with a poor prognosis.This study aims to comprehensively analyze the genomic characteristics of acral melanoma in East Asians.We conduct whole-genome sequencing of 55 acral melanoma tumors and perform data mining with relevant clinical data.Our findings reveal a unique mutational profile in East Asian acral melanoma,characterized by fewer point mutations and structural variations,a higher prevalence of NRAS mutations,and a lower frequency of BRAF mutations compared to patients of European descent.Notably,we identify previously underestimated ultraviolet radiation signatures and their significant association with BRAF and NRAS mutations.Structural rearrangement signatures indicate distinct mutational processes in BRAF-driven versus NRAS-driven tumors.We also find that homologous recombination deficiency with MAPK pathway mutations correlated with poor prognosis.The structural variations and amplifications in EP300,TERT,RAC1,and LZTR1 point to potential therapeutic targets tailored to East Asian populations.The high prevalence of whole-genome duplication events in BRAF/NRAS-mutated tumors suggests a synergistic carcinogenic effect that warrants further investigation.In summary,our study provides important insights into the genetic underpinnings of acral melanoma in East Asians,creating opportunities for targeted therapies.
文摘Bees play a crucial role in the global food chain,pollinating over 75% of food and producing valuable products such as bee pollen,propolis,and royal jelly.However,theAsian hornet poses a serious threat to bee populations by preying on them and disrupting agricultural ecosystems.To address this issue,this study developed a modified YOLOv7tiny(You Only Look Once)model for efficient hornet detection.The model incorporated space-to-depth(SPD)and squeeze-and-excitation(SE)attention mechanisms and involved detailed annotation of the hornet’s head and full body,significantly enhancing the detection of small objects.The Taguchi method was also used to optimize the training parameters,resulting in optimal performance.Data for this study were collected from the Roboflow platformusing a 640×640 resolution dataset.The YOLOv7tinymodel was trained on this dataset.After optimizing the training parameters using the Taguchi method,significant improvements were observed in accuracy,precision,recall,F1 score,andmean average precision(mAP)for hornet detection.Without the hornet head label,incorporating the SPD attentionmechanism resulted in a peakmAP of 98.7%,representing an 8.58%increase over the original YOLOv7tiny.By including the hornet head label and applying the SPD attention mechanism and Soft-CIOU loss function,themAP was further enhanced to 97.3%,a 7.04% increase over the original YOLOv7tiny.Furthermore,the Soft-CIOU Loss function contributed to additional performance enhancements during the validation phase.

文摘This study investigated the quasi-biweekly oscillation(QBWO)of the South Asian high(SAH)center in midsummer and its possible impact on rainfall in the middle and lower reaches of the Yangtze River Basin(MLYRB),using ERA5 reanalysis data and CPC(Climate Prediction Center)Global Unified Precipitation data from 1979-2023.First,associated with the phase evolution of the QBWO of the SAH center zonally,a general systematic westward propagation of a wave train pattern along the northern margin of the SAH can be identified.Second,energy analysis indicates that this wave train pattern gains energy from the basic flow through both barotropic and baroclinic energy conversion.Compared with barotropic energy conversion,baroclinic energy conversion plays the more important role in the growth,maintenance,and propagation of the wave train pattern associated with the QBWO of the SAH center.Third,the QBWO of the SAH center leads the variation in rainfall in the MLYRB by approximately four days,and might modulate the precipitation in the MLYRB by affecting the coupling of upper-and lower-level circulation anomalies over the MLYRB.The findings of this study suggest that the QBWO of the SAH center could act as potential source of predictability of intraseasonal variation in precipitation in the MLYRB.
