Policy Studies Journal, EarlyView.ABSTRACT This study examines the evolution of climate change discourse in the United States Congress from 1987 to 2017, employing natural language processing (NLP) techniques to analyze floor speeches. Using a la carte (ALC) word embeddings, we investigate how Democratic and Republican members of Congress frame climate change, focusing on denialist ...

Poverty &Public Policy, Volume 18, Issue 2, June 2026.ABSTRACT Cash transfers have become an increasingly important social protection tool in development and humanitarian contexts. In developing countries, cash transfers can be used to build economic resilience. This study examines the effects of unconditional cash transfers on asset accumulation among low‐income households in rural Northern Uganda. Using

Scale Estimates of Local Government Debt Based on “Public-pool” Translatable KMV models [PDF]
, 2016 2015年可被称为地方政府债务规模管理改革“元年”：中央政府对地方政府债务管理从规模和结构上采取了“开源节流，有堵有疏”的改革，开始正式对地方债实行限额管理；同时，中央政府也对转移支付制度进行完善和改革。这一系列改革措施都是围绕地方债管理的核心框架——控制债务规模，平衡债务结构建立的。如何根据目前政策及形势，对地方政府债务规模进行测算分析，确认地方政府发债上限，是目前的当务之急和重中之重，具有重要的理论意义和现实意义。 本文的思路与结构如下：首先给出地方政府债务规模的相关基本概念、特征及分类 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.

Zhongshan Daxue xuebao. Yixue kexue ban, 1987 本文报告自1964～1981年经外科治疗的女性单侧乳腺癌1656例,随访1—18年(中位11年),有128例发生骨转移,骨转移率为7.7％。骨转移的主要部位为脊柱(46.6％),肩胛带(15.1％),骨盆带(10.9％),显示乳腺癌的骨转移与肋间——脊椎静脉系统密切相关。本组术后发生骨转移的中位时间为22个月,发现骨转移后的中位生存时间为7个月。影响乳腺癌术后骨转移的主要因素为乳腺癌的病理组织学类型及区域淋巴结转移情况。作者认为预访和减少乳腺癌骨转移率的切实可行的措施是早期发现、早期诊断、早期治疗 ...

增强CT淋巴结形态联合错配修复蛋白表达检测对结直肠癌区域淋巴结转移的评估作用
Zhongguo shiyan zhenduanxue, 2023 目的 分析增强电子计算机断层扫描(CT)淋巴结形态联合错配修复蛋白(MMR)表达检测对结直肠癌区域淋巴结转移的评估作用。方法 选取2019年8月-2021年8月收治的结直肠癌患者89例，均采取手术治疗，术前行增强CT扫描及病理穿刺检测病灶组织MMR表达情况。以术中结果为标准，评价增强CT淋巴结形态联合MMR表达检测对直肠癌区域淋巴结转移的评估价值。结果 淋巴结转移患者高分化和pT3-4期百分率与淋巴结未转移患者比较，差异有统计学意义 ...

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Piezocatalytic technology utilizes mechanical strain or stress‐induced piezoelectric phenomena to produce robust internal electric fields, markedly improving the separation efficiency of e−‐h+ pairs. This method has emerged as a focal point in catalysis by removing reliance on conventional light or electrical energy via its mechanical‐to ...

The effects of axon guidance factor Slit3 on metastasis of human fibrosarcoma [PDF]
, 2015 我们通过在纤维肉瘤细胞HT1080过表达Slit3基因，分析Slit3对肿瘤细胞侵袭转移作用.Transwell侵袭实验中，Slit3过表达后抑制HT1080的迁移侵袭，在裸鼠皮下成瘤实验中，肿瘤体积明显变小、重量明显降低，Slit3过表达后抑制HT1080肿瘤细胞的侵袭转移。此外肿瘤切片HE染色后发现GFP组有病灶点，而slit3过表达则少见，这个结果说明，Slit3显著抑制HT1080细胞转移。slit3过表达后MMP2,MMP9的表达明显降低，而MMP3，MMP13表达量上调 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The stability of aqueous Zn2+ batteries is severely hindered by parasitic reactions at the Zn anode/electrolyte interface. Herein, itaconic acid (IA) is introduced as an effective electrolyte additive to achieve a highly stable zinc anode. Remarkably, IA concurrently modulates both the zinc anode/electrolyte interfacial structure and the Zn2 ...
