The Antarctic Ice Sheet（AIS） has been losing ice mass and contributing to global sea level rise（GSLR）. Given its mass that is enough to cause ～58 m of GSLR, accurate estimation of mass balance trend is critical for AIS mass loss monitoring and sea level rise forecasting. Here, we present an improved approach to reconciled solutions of mass balance in AIS and its regions from multiple contributing solutions using the input-out, altimetric, and gravimetric methods. In comparison to previous methods, such as IMBIE 2018, this approach utilizes an adaptive data aggregation window to handle the heterogeneity of the contributing solutions, including the number of solutions, temporal distributions, uncertainties, and estimation techniques. We improved the regression-based method by using a two-step procedure that establishes ensembled solutions within each method（input-output, altimetry, or gravimetry） and then estimates the method-independent reconciled solutions. For the first time, 16contributing solutions from 8 Chinese institutions are used to estimate the reconciled mass balance of AIS and its regions from1996 to 2021. Our results show that AIS has lost a total ice mass of ～3213±253 Gt during the period, an equivalent of～8.9±0.7 mm of GSLR. There is a sustained mass loss acceleration since 2006, from 88.1±3.6 Gt yr-1during 1996–2005 to 130.7±8.4 Gt yr-1during 2006–2013 and further to 157.0±9.0 Gt yr-1during 2014–2021. The mass loss signal in the West Antarctica and Antarctic Peninsula is dominant and clearly presented in the reconciled estimation and contributing solutions, regardless of estimation methods used and fluctuation of surface mass balance. Uncertainty and challenges remain in mass balance estimation in East Antarctica. This reconciled estimation approach can be extended and applied for improved mass balance estimation in the Greenland Ice Sheet and mountain glacier regions.

Layerwise third-order shear deformation theory with transverse shear stress continuity for piezolaminated plates

引用

CHINESE JOURNAL OF AERONAUTICS 2024年第9期37卷 490-505页

作者： Gao, Yingshan Zhang, Shunqi Hu, Wei Ma, songyun Markert, Bernd Shanghai Univ Sch Mech Engn & Automat Shanghai 200444 Peoples R China Shanghai Univ Key Lab Silicate Cultural Rel Conservat Minist Educ Shanghai 200444 Peoples R China Rhein Westfal TH Aachen Inst Gen Mech D-52062 Aachen Germany

Regarding laminated structures, an electromechanically coupled Finite Element (FE) model based on Layerwise Third-Order Shear Deformation (LW-TOSD) theory is proposed for static and dynamic analysis. LW-TOSD ensures the continuity of in-plane displacements and transverse shear stresses. The current LW-TOSD can be applied to arbitrary multi-layer laminated structures with only seven Degrees of Freedom (DOFs) for each element node and eliminates the use of the shear correction factors. Moreover, a shear penalty stiffness matrix is constructed to satisfy artificial constraints to optimize the structural shear strain. A dynamic finite element model is obtained based on LW-TOSD using the Hamilton's principle. First, the accuracy of the current model is validated by comparing with literature and ABAQUS results. Then, this study carries out numerical investigations of piezolaminated structures for different width-to-thickness ratios, length-to-width ratios, penalty stiffness matrix, boundary conditions, electric fields and dynamics.

The in-depth transmission and reception process of the factors influencing review helpfulness from the signaling timeline perspective

中国科学技术大学学报 2024年

Many existing studies have considered the factors influencing review helpfulness, mainly focusing on reviewer impact, review informativeness, and managerial response, based on signaling theory. However, previous studies have simply regarded these factors as independent signals, thus ignoring their in-depth transmission and reception *** conclusions about the impact of reviewers on review helpfulness are also inconsistent due to the inaccurate measurement of variables. To fill the above gaps, we followed the signaling timeline theoretical framework used in signaling theory and employed a bootstrapping analysis to examine how reviewer impact, review informativeness, and hotel managerial responses interact to influence review helpfulness. In this study, we used a unique dataset that included official labels from one leading online travel agency. The results show that reviewer impact may affect review helpfulness sequentially through review informativeness and hotel managerial response. Furthermore, by using official labels, both reviewer expertise and reviewer experience significantly affect review helpfulness. Finally, we discuss the theoretical and practical implications of these findings.

目的探讨以急变期为首发的慢性粒细胞白血病（CML）患者的临床和实验室特征。方法分析2015年1月至2016年11月郑州大学附属洛阳中心医院收治的3例以急变期为首发的CML患者的临床和实验室特征及诊疗经过，患者首发症状均类似急性白血病。结果3例患者主要表现均为脾大、外周血白细胞计数明显升高、骨髓中原始细胞大量增殖、骨髓中期相细胞费城染色体阳性（Ph＋），荧光原位杂交分析分叶粒细胞可检测到bcr-abl1融合信号，bcr-abl1融合基因p210阳性，缺乏典型的CML慢性期病史。结论以急变期为首发的CML患者由于骨髓中存在大量原始细胞，且临床表现类似于急性白血病，从而在初诊时易被误诊为Ph＋急性白血病，临床表现、遗传学及基因组学有助于鉴别诊断。
