Future meteorological drought conditions in southwestern Iran based on the NEX-GDDP climate dataset

Investigation of the climate change effects on drought is required to develop management strategies for minimizing adverse social and economic impacts.Therefore,studying the future meteorological drought conditions at a local scale is vital.In this study,we assessed the efficiency of seven downscaled Global Climate Models(GCMs)provided by the NASA Earth Exchange Global Daily Downscaled Projections(NEX-GDDP),and investigated the impacts of climate change on future meteorological drought using Standard Precipitation Index(SPI)in the Karoun River Basin(KRB)of southwestern Iran under two Representative Concentration Pathway(RCP)emission scenarios,i.e.,RCP4.5 and RCP8.5.The results demonstrated that SPI estimated based on the Meteorological Research Institute Coupled Global Climate Model version 3(MRI-CGCM3)is consistent with the one estimated by synoptic stations during the historical period(1990-2005).The root mean square error(RMSE)value is less than 0.75 in 77%of the synoptic stations.GCMs have high uncertainty in most synoptic stations except those located in the plain.Using the average of a few GCMs to improve performance and reduce uncertainty is suggested by the results.The results revealed that with the areas affected by wetness decreasing in the KRB,drought frequency in the North KRB is likely to increase at the end of the 21st century under RCP4.5 and RCP8.5 scenarios.At the seasonal scale,the decreasing trend for SPI in spring,summer,and winter shows a drought tendency in this region.The climate-induced drought hazard can have vast consequences,especially in agriculture and rural livelihoods.Accordingly,an increasing trend in drought during the growing seasons under RCP scenarios is vital for water managers and farmers to adopt strategies to reduce the damages.The results of this study are of great value for formulating sustainable water resources management plans affected by climate change.

Epigenetic patterns in a complete human genome

The completion of a telomere-to-telomere human reference genome,T2T-CHM13,has resolved complex regions of the genome,including repetitive and homologous regions.Here,we present a high-resolution epigenetic study of previously unresolved sequences,representing entire acrocentric chromosome short arms,gene family expansions,and a diverse collection of repeat classes.This resource precisely maps CpG methylation(32.28 million CpGs),DNA accessibility,and short-read datasets(166,058 previously unresolved chromatin immunoprecipitation sequencing peaks)to provide evidence of activity across previously unidentified or corrected genes and reveals clinically relevant paralog-specific regulation.Probing CpG methylation across human centromeres from six diverse individuals generated an estimate of variability in kinetochore localization.This analysis provides a framework with which to investigate the most elusive regions of the human genome,granting insights into epigenetic regulation.

PIKFYVE inhibition mitigates disease in models of diverse forms of ALS

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that results from many diverse genetic causes.Although therapeutics specifically targeting known causal mutations may rescue individual types of ALS, these approaches cannottreat most cases since they have unknown genetic etiology. Thus, there is a pressing need for therapeutic strategies that rescuemultiple forms of ALS. Here, we show that pharmacological inhibition of PIKFYVE kinase activates an unconventional proteinclearance mechanism involving exocytosis of aggregation-prone proteins. Reducing PIKFYVE activity ameliorates ALSpathology and extends survival of animal models and patient-derived motor neurons representing diverse forms of ALS includingC9ORF72, TARDBP, FUS, and sporadic. These findings highlight a potential approach for mitigating ALS pathogenesis that doesnot require stimulating macroautophagy or the ubiquitin-proteosome system.

Matching Consequences and Causes in Crisis Public Relations

This exploratory study examines the phenomenon of consequence cause matching,which is based on the representativeness heuristic,from cognitive psychology,upon crisis management and public relations.A 2(Large Scale Crisis vs.Small Scale Crisis)×2(Large Scale Cause vs.Small Scale Cause)mixed factorial design experiment was conducted based upon a hypothetical crisis scenario.This study found initial evidence that consequence cause matching is a phenomenon that can impact the process of attribution for a crisis.It highlights a potential new area of theoretical growth for the situational crisis communication theory.

Spatial Domain Technique for Visible Watermarking

A new technique for embedding visible watermarks into a digital image isdescribed in this paper, which uses statistical properties of each pixel and its immediatesurrounding pixels in the host image, and also the statistical properties of the host image and thatof the image to be embedded (watermark), as the pixels in the host image are replaced one by one bythe pixels in the watermark image. The aim is to establish a relationship between pixels in theimages that will make the embedded watermark robust and semitransparent, and to minimize errorscaused by watermark addition and subtraction. Also, the original image can be completelyreconstructed from the watermarked images.

New Chronological Evidence for Indosinian Diagenetic Mineralization in Eastern Xinjiang, NW China

There have been conflicting ideas about the Indosinian mineralization in E. Xinjiang, a subject that has attracted many geologists' attention over a long period. Isotopic dating shows that the Shiyingtan gold deposit located on the southern margin of the Turpan-Hami basin has a quartz fluid inclusion Rb-Sr isochron age of 237±9 Ma (95% conf.); the Shuangfengshan gold deposit on the southern margin of the Junggar orogenic belt has a quartz fluid inclusion Rb-Sr isochron age of 226 ±21 Ma (95% conf.); the Weiya vanadium-titanium magnetite in the E. Tianshan mountains has a mineral-whole rock Sm-Nd isochron age of 220 ±30 Ma (95% conf.); the Jinwozi and Jinwozi 210 gold deposits in the E. Tianshan mountains have quartz fluid inclusion Rb-Sr isochron ages of 228±22 Ma (95% conf.) and 230±6 Ma (95% conf.), respectively; and the Xiaobaishitouquan scheelite deposit in the E. Tianshan mountains has a quartz fluid inclusion Rb-Sr isochron age of 248±7 Ma (95% conf.). The metallogenetic ages mentioned above prove the existence of Indosinian mineralization in E. Xinjiang, and the metallogenetic event might have been related to Triassic intraplate magmatic evolution, intra-continent subduction, strike-slip shoving and ductile shearing in the studied area, representing another mineralization peak after the Late Paleozoic.

GGE biplot analysis of yield stability and test location representativeness in proso millet (Panicum miliaceum L.) genotypes

The experiments were conducted for three consecutive years across 14 locations using 9 non-waxy proso millet genotypes and 16 locations using 7 waxy proso millet genotypes in China. The objectives of this study were to analyze yield stability and adaptability of proso millets and to evaluate the discrimination and representativeness of locations by analysis of vari- ance （ANOVA） and genotype and genotype by environment interaction （GGE） biplot methods. Grain yields of proso millet genotypes were significantly influenced by environment （E）, genotype （G） and their interaction （GxE） （P〈0.1%）. GxE inter- action effect was six times higher than G effect in non-waxy group and seven times in waxy group. N04-339 in non-waxy and Neimi 6 （NM6） in waxy showed higher grain yields and stability compared with other genotypes. Also, Neimi 9 （NM9, a non-waxy cultivar） and 90322-2-33 （a waxy cultivar） showed higher adaptability in 7 and in 11 locations, respectively. For non-waxy, Dalat, Inner Mongolia （E2） and Wuzhai, Shanxi （E5） were the best sites among all the locations for maximizing the variance among candidate cultivars, and Yanchi, Ningxia （El0） had the best representativeness. Wuzhai, Shanxi （e9） and Yanchi, Ningxia （e14） were the best representative locations, and Baicheng, Jilin （e2） was better discriminating location than others for waxy genotypes. Based on our results, El0 and e14 have enhanced efficiency and accuracy for non-waxy genotypes and waxy genotypes selection, respectively in national regional test of proso millet varieties.

An Analysis of Historical and Future Temperature Fluctuations over China Based on CMIP5 Simulations

The trends and fluctuations of observed and CMIP5-simulated yearly mean surface air temperature over China were analyzed.In general,the historical simulations replicate the observed increase of temperature,but the multi-model ensemble （MME） mean does not accurately reproduce the drastic interannual fluctuations.The correlation coefficient of the MME mean with the observations over all runs and all models was 0.77,which was larger than the largest value （0.65） from any single model ensemble.The results showed that winter temperatures are increasing at a higher rate than summer temperatures,and that winter temperatures exhibit stronger interannual variations.It was also found that the models underestimate the differences between winter and summer rates.The ensemble empirical mode decomposition technique was used to obtain six intrinsic mode functions （IMFs） for the modeled temperature and observations.The periods of the first two IMFs of the MME mean were 3.2 and 7.2,which represented the cycle of 2-7-yr oscillations.The periods of the third and fourth IMFs were 14.7 and 35.2,which reflected a multi-decadal oscillation of climate change.The corresponding periods of the first four IMFs were 2.69,7.24,16.15 and 52.5 in the observed data.The models overestimate the period of low frequency oscillation of temperature,but underestimate the period of high frequency variation.The warming rates from different representative concentration pathways （RCPs） were calculated,and the results showed that the temperature will increase by approximately 0.9℃,2.4℃,3.2℃ and 6.1℃ in the next century under the RCP2.6,RCP4.5,RCP6.0 and RCP8.5 scenarios,respectively.
