Quantifying Model Selection Uncertainty in Structural Analysis: Methodology and Application

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT With increasing focus on complex engineering systems under rare events, computational models are critical for predictions due to the scarcity or absence of data. However, selecting an appropriate model can be challenging. Using a single model without available test calibration could result in significant bias in performance predictions. A case

Full scale pumping tests on SCC: application of the modified Hattori-Izumi theory [PDF]

, 2009
Studying the flow of fresh concrete is influenced by time dependency of the rheological properties of the concrete. This time dependency can be divided into two parts : the non-reversible part, being loss of workability and the reversible part, called ...

Technology Development Outsourcing: When to Join Forces With a Rival?

Journal of Operations Management, EarlyView.
ABSTRACT Knowing the challenges of collaborating with a competitor in developing new technologies, firms sometimes still choose a competitor instead of a noncompeting technology provider. To explore why, this study adopts an inter‐organizational trust view to explain the formation of a technology development outsourcing relationship.

Fritz Scheffer Under National Socialism: Assessing His Political Involvement

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Aims This article examines the role of soil scientist Fritz Scheffer (1899–1979) under National Socialism and offers a critical assessment of his scientific, institutional, and political positioning between 1933 and 1945. It asks how Scheffer shaped his career within the tension between disciplinary specialization, political expectations, and ...

Measuring Organizational Resilience in a Resource‐Constrained Environment: An Empirical Study of Micro‐and‐Small‐Service‐Enterprises (MSSEs) in Nigeria

Strategic Change, EarlyView.
ABSTRACT There is growing evidence that a preponderance of resilience indicators discussed in management scholarship is often developed with limited consideration of the context in which micro‐and‐small‐service enterprises (MSSEs) operate. Given their strategic relevance to developing economies, it thus becomes necessary to understand the meaning of ...

Early Dapagliflozin and Melatonin Treatment Ameliorated LV Fibrosis via Suppressing TGF‐β1/Smads and Activating Nrf2‐ARE Signaling in MI Rodent

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study tested whether combined dapagliflozin (DAPA) and melatonin (Mel) therapy was superior to merely one for ameliorating the left ventricular (LV) fibrosis/remodeling and improving LV ejection fraction (LVEF) in rats after acute myocardial infarction (AMI). In vitro study demonstrated that DAPA treatment significantly suppressed the TGF‐
