Cilostazol in patients with heart failure and preserved ejection fraction—The CLIP‐HFpEF trial

ESC Heart Failure, Volume 12, Issue 2, Page 1437-1446, April 2025.
• Cilostazol is an oral PDE‐3 inhibitor that may have advantageous effects in heart failure with preserved ejection fraction (HFpEF). • Cilostazol significantly improved short‐term heart failure‐related health status scores (KCCQ‐12) and NT‐proBNP levels when compared to placebo.

MCMs: enabling GaAs?

III-Vs Review, 1997
AbstractThe multi-chip module (MCM) is another one of those enabling technologies that has its champions and its critics. But it looks likely that MCMs are presenting a serious challenge to the traditional ASIC design route. Designers are using MCMs which combine the best available devices—silicon and GaAs—at their initial design iteration stages ...

Impact of Uncertain Parameters on Navier–Stokes Equations With Heat Transfer via Polynomial Chaos Expansion

International Journal for Numerical Methods in Fluids, EarlyView.
This study investigates the impact of uncertain parameters on Navier–Stokes equations coupled with heat transfer using the Intrusive Polynomial Chaos Method (IPCM). Sensitivity equations are formulated for key input parameters, such as viscosity and thermal diffusivity, and solved numerically using the Finite Element‐Volume method.

Influence of microwave energy on temperature field distribution and properties evolution characteristics of cement mortar containing magnetite

Journal of Traffic and Transportation Engineering (English ed. Online)
To improve the microwave absorption ability of cement mortar, this study focused on the preparation of magnetite cement mortar (MCM) with magnetite as the main absorbing material. The electromagnetic (EM) parameters of MCM were measured and the microwave

Influence of functional silanes on hydrophobicity of MCM-41 synthesized from rice husk

Science and Technology of Advanced Materials, 2007
Mesoporous molecular sieve MCM-41 was synthesized from rice husk and rice husk ash, called RH-MCM-41 and RHA-MCM-41. The sol–gel mixtures were prepared with molar composition of 1.0 SiO2: 1.1 NaOH: 0.13 CTAB: 0.12 H2O.
