Zhongshan Daxue xuebao. Yixue kexue ban, 1996 肝ＣＴ延迟增强扫描的机理与肝组织的泌碘、聚碘功能有关。自１９８５年至１９９４年，作者对１２０例肝占位性病变的患者进行了ＣＴ延迟增强扫描，根据病变延迟增强扫描的特征，将之分为泌碘性病变与非泌碘性病变两种类型：肝癌、转移瘤、血管瘤、囊肿属非泌碘功能占位病变；肝腺瘤样增生结节、肝局灶性结节状增生属泌碘功能占位病变；并讨论上述病变延迟增强征象。机理及临床意义。

Conservation Biology, EarlyView.Abstract Robust estimates of the magnitude of protected species bycatch are essential for effective fisheries management and marine conservation. Existing bycatch estimation methods typically struggle to accurately and precisely estimate the bycatch of rare species as a result of the statistical assumptions necessary to overcome infrequent encounters ...

, 1994 本文提出了一个新的材料延性动态损伤模型;模型中不但包括了率效应;同时还考虑了惯性效应、孔洞表面能变化和材料硬化对孔洞演化的影响．此外;在模型中同时考虑了体应力和偏应力对孔洞演化的作用．从孔洞演化方程直接得到了孔洞增长和压缩应力临界表达式;Ｃａｒｒｏｌｌ和Ｈｏｌｔ的结果作为该表达式的一个特例而得出．模型的数值分析得出以下结论：①延性孔洞的动态增长对率效应十分敏感;应变率越高;孔洞增长越快；②惯性效应在高加载率条件下对孔洞增长有明显的影响;具体表现为对孔洞增长的阻碍作用．除此之外 ...

Running With Scissors? Integrating GPT Models Into Public Policy Research
Policy Studies Journal, EarlyView.ABSTRACT The integration of large language models (LLMs) into public policy research presents both exciting opportunities and methodological challenges. This research note explores how OpenAI's GPT can be used to semi‐automate the annotation of legislative testimony within the Advocacy Coalition Framework, focusing on emotion‐belief dyads.

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Wide‐bandgap perovskite solar cells (WBG PSCs) have attracted significant attention as the top cell in tandem perovskite solar cells. However, the complexity of the composition leads to challenges such as defect formation and phase separation during the crystallization process, which impose significant constraints on the power conversion ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT A thermomechanical strategy based on rolling‐annealing cyclic (RAC) was developed to regulate defect architecture and precipitation behavior in a (FeCoCrNi)94Al3Ti3 high‐entropy alloy. Intermediate annealing during rolling enables progressive grain refinement and introduces a high density of twins, stacking faults, and dislocations, forming a ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT The exceptional ductility of face‐centered cubic high/medium‐entropy alloys (H/MEAs) is counterbalanced by intrinsically restrained yield strength, fundamentally compromising their application in structural and functional materials. Here, a novel carbon (C)‐driven precipitation strategy is introduced to promote discontinuous precipitation (DP)

GHK‐Cu Delays Aging Through the Repair of Mitochondrial Dysfunction
Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Althugh glycyl‐L‐histidyl‐L‐lysine copper (GHK‐Cu) shows antiaging potential, its precise molecular mechanisms remain unclear. Using Caenorhabditis elegans (C. elegans) as an in vivo aging model, we observed that GHK‐Cu extended organismal lifespan and improved stress resilience.
