Governing by Ambiguity: Sociotechnical Imaginaries of Platforms in China
Policy &Internet, Volume 18, Issue 2, June 2026.ABSTRACT Besides clear policy directives, the unresolved and open‐ended elements in policy communication also create discursive politics. This article argues that ambiguity in policy communication reflects the state's exercise of power within a fractured sociocultural landscape.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Titanium (Ti)–steel composite joints are prone to the formation of compounds such as TiC, TiFe, and TiFe2 during solid‐phase bonding. This phenomenon leads to premature failure and significantly reduces the bonding quality of the joints. However, the fracture behavior of the joint influenced by these compounds, particularly on the initiation ...

Dizhen xuebao川滇地块是世界上构造活动与地震活动最活跃的地区之一，区内强震多集中于地块边界断裂上，而地块内部断裂的活动性及发震潜力尚未得到足够的关注。在川滇地块内部凉山州地区进行断层普查时发现一条明显的岩性分界线，将其命名为踩马水断裂。该断裂为川滇地块内部的一条NE向断裂，全长约80 km，目前其最新活动时代、运动性质、地震危险性和区域构造作用等研究仍处于空白状态。本研究综合运用遥感解译、野外调查、无人机测绘、探槽开挖和第四纪测年等多种方法，对踩马水断裂进行系统性的研究，明确了其几何展布特征 ...

Dizhen xuebao, 2019 通过建立三维数值模型，对隐伏正断层在均匀错动和倾斜错动方式下土体的破裂过程进行研究。利用应力罗德参数和等效塑性应变分别对断层错动过程中上覆土体的应力状态和破坏形式进行分析，并提出土体破裂的判别方法。通过对数值模拟结果的分析得到以下结论：① 在断层错动过程中，下盘一侧受断层错动影响的上覆土体的应力状态经压剪→纯剪→拉剪逐渐变化，而上盘一侧上覆土体的应力状态变化较为复杂，经压剪→纯剪→拉剪→纯剪→压剪重复变化；② 在断层均匀错动过程中，断层下盘一侧土体的破裂率先出现在地表拉剪区内，随错动量的增大 ...

ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis
Veterinary Dermatology, Volume 37, Issue 3, Page 365-374, June 2026.ABSTRACT Background Ichthyosis fetalis (IF), also known as harlequin ichthyosis, is a rare and often fatal autosomal recessive congenital skin disorder. It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears.

Dizhen xuebao, 2019 对鲜水河断裂带重磁异常进行向上延拓，通过计算观测面高度异常与延拓后异常之间的相关系数得出最佳向上延拓高度，该延拓高度所对应的延拓结果即为研究区构造背景产生的异常值。向上延拓结果显示布格重力异常值沿鲜水河断裂带自北西向南东逐渐增大，反映出下地壳底边界沿该方向呈升高趋势，可能由青藏高原地壳软弱物质 “东向逃逸” 所致。化极后ΔT磁异常延拓结果表明鲜水河断裂带南东段的康定—石棉以东为强磁性刚性基底。以鲜水河断裂带为分界的不同地块之间基底岩石及地层物性的不同是断裂带南北磁性差异的主导原因 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The inherent brittleness of hardmetals stems from the rigid covalent bond in the ceramic matrix and the sharp ceramic/metal interface, which restricts the nucleation and motion of dislocations. In this study, a novel strategy is proposed to activate significant dislocation behaviors in the WC matrix by employing a non‐equiatomic CoNiFeCr ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT This study demonstrates a new strategy for modifying the boron content to address stress‐relief cracking (SRC) in the 7CrMoVTiB10.10 alloy. First, coarse‐grained heat‐affected zone (CGHAZ) specimens with different boron contents were prepared via simulated welding thermal cycles.
