Clinically Relevant Bleeding in Individuals With Cancer: Insights From a Nationwide Cohort Study

American Journal of Hematology, EarlyView.
ABSTRACT Cancer care is often complicated by coagulopathy leading to thrombosis and bleeding. While venous thromboembolism (VTE) has been extensively studied, bleeding remains an underestimated threat. To address this knowledge gap, we leveraged the Epic Cosmos database to determine the impact of cancer‐associated clinically relevant bleeding (CRB) in ...

Commutation Failure Predictive Control Based on Fast AC Voltage Measurement in LCC-HVDC

IEEE Access, 2023
To inhibit commutation failure (CF), in this paper, the influence factors of CF were analyzed, and considering different fault types and different valves, the mathematical expression of extinction angle was deduced.

Sleep‐trackers in the wild: A faceted taxonomy for information and interaction design

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Consumer‐grade sleep‐tracking technologies (CSTs) have brought sleep into everyday data practices, reframing it from a clinical concern into a site of personal optimization and reflection. Yet existing taxonomies of sleep‐tracking often medicalize users and overlook the complexity of sleep‐tracking technologies. This paper presents SleepTax, a

A pipeline crisis or a sustainability crisis? Local and national succession planning for headteachers in England

British Educational Research Journal, EarlyView.
Abstract Recruiting and retaining school leaders is a challenge in many systems worldwide. Previous research has identified three distinct ways in which succession planning can be conceptualised and approached: a ‘pipeline’ approach seeks to match supply and demand for the posts that need filling; a ‘pool’ strategy involves proactively identifying and ...

Commutation Failure Prevention for HVDC Improvement in algorithm for commutation failure prevention in LCC HVDC

, 2016
Line commutated HVDC systems are widely used due to their high power ratings. However, one of the disadvantages of such HVDC systems is the high risk of commutation failures when AC disturbances arise.

Addressing racialised awarding gap in higher education: Insights from personal tutors

British Educational Research Journal, EarlyView.
Abstract Situated within a wider cross‐institutional research project, this article provides an in‐depth case study of one higher education (HE) institution, focusing on how personal tutors make sense of racialised degree awarding disparities for both undergraduate and postgraduate students, how they perceive their responsibilities, the challenges and ...

What Do We Know About Scope 3 Emissions in Small‐ and Medium‐Sized Enterprises? Mapping Current Knowledge and Advancing a Theory–Practice‐Oriented Framework

Business Strategy and the Environment, EarlyView.
ABSTRACT Although SMEs comprise over 90% of firms globally, research on their engagement with Scope 3 (value‐chain) greenhouse gas emissions remains limited. This PRISMA‐guided systematic review synthesises 49 SME‐relevant studies to develop a theory‐informed, practice‐oriented framework for more credible and sustained Scope 3 engagement.

Landscape of Research on Accounting Scope 3 Emissions: A Review of Methodologies and Data

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Scope 3 emissions have been proposed as a critical metric for evaluating corporate carbon footprint, identifying emission sources, and developing mitigation solutions. Yet, widespread corporate reporting of Scope 3 emissions remains limited, highlighting a critical gap in both research and practice.
