大陸地區課程發展機制的結構層次與關係The Structural Hierarchy and Relations of the Curriculum Development Mechanism in Chinese Mainland

open access: yesJournal of Curriculum Studies, 2011
中央集權機制、地方分權機制與學校自主機制是課程發展機制的三種基本型 態。在大陸地區,儘管在管理體制上基礎教育主要由地方負責,但在課程發展方面 卻是典型的中央集權機制,實行的是統一的國家課程發展策略,並且通過自上而下 的行政推動來實施。 大陸地區在統一的國家課程框架下,課程發展機制呈現出明顯的層次性結構特 徵,不同層次間存在著主導、輔助、強化、補償、監督及調適等多重作用和複雜關 係,共同影響著課程發展機制系統的運行走向和功能效應。 由於統一的國家課程難以適應不同地區、學校和學生的差異性,所以國家課程 ...

On time hierarchies

open access: yesProceedings of the ninth annual ACM symposium on Theory of computing - STOC '77, 1977
AbstractFor fixed k ⩾ 2 we tighten the time hierarchy for k-tape Turing machines. Also for fixed k ⩾ 2 we exhibit infinite hierarchies of languages recognizable by k-tape machines with machines with increasing amount of time on the same amount of space.

Association Between Sleep Disturbance and Subsequent Pain Interference in Patients With Early Rheumatoid Arthritis

open access: yesArthritis Care &Research, EarlyView.
Objective This study investigated whether sleep disturbance can predict the extent to which pain interferes with daily functioning in patients with early rheumatoid arthritis (RA). Methods Data were from adults with early RA (joint symptoms ≤12 months) enrolled in the Canadian Early Arthritis Cohort between 2016 and 2023.

Whole‐Blood RNA Sequencing Profiling of Patients With Rheumatoid Arthritis Treated With Tofacitinib

open access: yesACR Open Rheumatology, EarlyView.
Objective Patients with rheumatoid arthritis (RA) often fail to respond to therapies, including JAK inhibitors (JAKi), and treatment allocation is made via a trial‐and‐error strategy. A comprehensive analysis of responses to JAKi, including tofacitinib, by RNA sequencing (RNAseq) would allow the discovery of transcriptomic markers with a two‐fold ...

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Interspecific variation of calls in clownfishes: degree of similarity in closely related species

open access: yesBMC Evolutionary Biology, 2011
Background Clownfishes are colorful coral reef fishes living in groups in association with sea anemones throughout the Indo-Pacific Ocean. Within their small societies, size hierarchy determines which fish have access to reproduction.

Performance Triggered Adaptive Model Reduction for Soil Moisture Estimation in Precision Irrigation

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
ABSTRACT Accurate soil moisture information is essential for precise irrigation to enhance water use efficiency. Estimating soil moisture based on limited soil moisture sensors is especially critical for obtaining comprehensive soil moisture information when dealing with large‐scale agricultural fields.

Hyperoxia Induced Alteration of Chromatin Structure in Human Bone Marrow Derived Primary Mesenchymal Stromal Cells

open access: yesAdvanced Biology, EarlyView.
Chromatin, which organizes DNA, changes its structure to adapt to stress like high oxygen levels (hyperoxia), which can damage cells. Researchers developed a technique to observe these changes and found variability in how different parts of chromatin remodel.
