PD-L1在卵巢高级别浆液性癌预后中的价值

open access: yesZhongguo shiyan zhenduanxue, 2020
为了进一步了解PD-L1和CD8在卵巢癌中的表达情况以及评价其对预后的预测价值,我们建立了近10年来在我院完成初次肿瘤细胞减灭术治疗的卵巢高级别浆液性癌患者的临床病例资料库,进行回顾性分析及随访调查,研究影响卵巢高级别浆液性癌患者预后的相关临床及病理因素。同时制作卵巢高级别浆液性癌患者的病理组织芯片,通过免疫组织化学染色评价相关蛋白在卵巢癌病灶中的定位及表达水平情况,研究PD-L1和CD8在卵巢高级别浆液性癌中是否存在表达差异,同时分析蛋白表达强度与预后是否存在相关性,从而进一步验证PD ...

Profiling EFL Students’ Motivation and Anxiety in Collaborative Learning: Associations With Teachers’ Support, Self‐Regulated Learning, and Achievement

open access: yesInternational Journal of Applied Linguistics, Volume 36, Issue 2, Page 979-994, May 2026.
ABSTRACT Previous research has established the relationships between motivation, anxiety, teachers’ support, and self‐regulated learning (SRL) in English‐as‐a‐foreign‐language (EFL) learning. Most of the studies, however, have taken a variable‐centered approach in addressing the variable correlations, while learners’ characteristics and variable links ...

基于特征参量优选与多算法联合的局部放电模式识别方法

open access: yesGaoya dianqi, 2018
电力设备中,不同类型的放电因放电功率、能量的差异对设备绝缘的损害能力存在差异,即对绝缘的危害程度不同,确定局部放电类型是放电危险度评估的基础。文中对典型缺陷条件下的局部放电谱图提取了基本参量及统计参量等多种特征指纹;为了降低识别参量的维度,定义了特征向量可分性评估准则,并使用浮动前向搜索算法选取了可分性最优的9组特征参量;分别使用主成分分析、线性可分性分析、核主成分分析及通用可分性分析4种方法将特征向量降为2维,结果表明,使用通用可分性分析降维后特征参量可分性最优。之后,提出了多算法联合的模式识别分类器,

New Approach to Supporting Stakeholders in English Medium Instruction through a Global Online Community

open access: yesInternational Journal of Applied Linguistics, Volume 36, Issue 2, Page 1606-1614, May 2026.
ABSTRACT With the internationalisation of higher education, English medium instruction (EMI) has become increasingly common in non‐English‐speaking contexts. However, research highlights a range of challenges in EMI implementation, including insufficient collaboration between content and language teachers, limited professional development opportunities

Attainment Pairing Effects on Cognitive Conflict in Technology‐enhanced EFL Cooperative Tasks

open access: yesInternational Journal of Applied Linguistics, Volume 36, Issue 2, Page 1594-1605, May 2026.
ABSTRACT This study examines how attainment pairing (high‐high versus high‐low versus low‐low attainment) impacts English as a Foreign Language (EFL) learner engagement during technology‐enhanced cooperative writing tasks. Seventy‐eight Chinese university learners formed 39 dyads (13 pairs per group) via Tencent Meeting.

Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners

open access: yesInternational Journal of Applied Linguistics, Volume 36, Issue 2, Page 1807-1820, May 2026.
ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.

恶性肿瘤患者血清和尿中假尿苷检测的意义 附视频

open access: yesZhongguo shiyan zhenduanxue, 1997
为探讨血清和尿中假尿苷(ψ)对恶性肿瘤的诊断价值,用高效液相色谱法测定了50例正常人、68例鼻咽癌、42例原发性肝癌、41例肺癌、24例急性白血病和相应部位良性疾病患者血清和尿中ψ的含量。正常人的血清和尿中ψ水平分别为3.08±0.49nmol/ml、21.6±2.9nmol/μmol肌酐。鼻咽癌、原发性肝癌、肺癌、急性白血病患者血清ψ分别为4.32±1.40、6.74±3.44、5.10±1.92、6.00±2.01nmol/ml,尿ψ分别为28.6±6.2、36.9±11.7、31.9±8.3、35.

Narrative formatting, chronotopic orderings, and moralization in ex‐gay stories

open access: yesJournal of Linguistic Anthropology, Volume 36, Issue 1, May 2026.
Abstract Formatted stories rely on spatiotemporal cues to evoke recognizability through linearity, which prescribes a particular template for meaning‐making. This article examines stories narrated by ex‐gay members of a Christian organization in Singapore and considers how chronotopes within the stories are ordered to regiment ways of feeling for ...

Non‐Members in a Tight Spot: How Norway Navigated Autonomy in EU Pandemic Management

open access: yesReview of Policy Research, Volume 43, Issue 3, May 2026.
ABSTRACT This study offers new insights into how closely integrated non‐member states navigate tensions between autonomy and dependence when urgent policy responses are required within complex supranational frameworks. It does so by exploring how these non‐members exercise their “wriggle room”—a tailored sub‐category of the broader concept of autonomy ...
