Two questions in the research of animal personality—whether there is a correlation between a personality trait and individual reproductive success,and what is the genetic basis underlying a personality trait—remain *** addressed these two questions in three shrub-nesting birds,the Azure-winged Magpie(Cyanopica cyanus,AM),White-collared Blackbird(Turdus albocinctus,WB),and Brown-cheeked Laughingthrush(Trochalopteron henrici,BL).The personality type of an individual was first identified according to its response to a territorial ***,we compared the fleeing distance,breeding parameters,and differential expressed genes(DEGs) in the brain transcriptome between bold and shy *** the three species,bold breeders exhibited more aggressiveness towards an intruder of their territory than did shy *** reproductive success of bold breeders was significantly higher than that of shy breeders in AM but not in WB and *** three species shared one DEG,crabp1,which was up-regulated in bold relative to in shy *** regulating the expression of corticotropin-releasing hormone,higher crabp1 gene expression can decrease cellular response to retinoic ***,bold individuals are insensitive to external stresses and able to exhibit more aggressiveness to intruders than their shier *** is beneficial to bold individuals in AM but not in WB and BL because the former could evoke neighbors to make the same response of defending against intruders but the latter could *** a personality trait may have the same genetic basis across species,its correlation with reproductive success depends largely on the life history style of a species.

National Science Review 2024年第7期11卷 69-70页

作者： Lingeswaran Arunagiri feng gao Department of Physics Chemistry and Biology(IFM) Link?ping University

The maximum theoretical power conversion efficiency(PCE) for single-junction solar cells based on the Shockley-Queisser(S-Q) model is 33.7% for an optimal bandgap(Eg) of 1.34 eV under 1-sun illumination [1]. Multijunction(tandem) solar cells present a realistic option for overcoming the S-Q limit and achieving efficiency of >40%due to decreased thermalization loss in tandem configuration [2].

Bayesian partial pooling to reduce uncertainty in overcoring rock stress estimation

The state of in situ stress is a crucial parameter in subsurface engineering,especially for critical projects like nuclear waste *** one of the two ISRM suggested methods,the overcoring(OC)method is widely used to estimate the full stress tensors in rocks by independent regression analysis of the data from each OC ***,such customary independent analysis of individual OC tests,known as no pooling,is liable to yield unreliable test-specific stress estimates due to various uncertainty sources involved in the OC *** address this problem,a practical and no-cost solution is considered by incorporating into OC data analysis additional information implied within adjacent OC tests,which are usually available in OC measurement ***,this paper presents a Bayesian partial pooling(hierarchical)model for combined analysis of adjacent OC *** performed five case studies using OC test data made at a nuclear waste repository research site of *** results demonstrate that partial pooling of adjacent OC tests indeed allows borrowing of information across adjacent tests,and yields improved stress tensor estimates with reduced uncertainties simultaneously for all individual tests than they are independently analysed as no pooling,particularly for those unreliable no pooling stress estimates.A further model comparison shows that the partial pooling model also gives better predictive performance,and thus confirms that the information borrowed across adjacent OC tests is relevant and effective.
