Small, EarlyView.A one‐step in situ fabrication produces Pt‐segregated nanoparticles encapsulated in porous carbon shells. This design drastically reduces Pt content while maintaining high oxygen reduction reaction activity and long‐term durability. The catalyst meets DOE targets even at ultralow Pt loading, presenting a practical pathway toward cost‐effective, high ...

The Journal of Physiology, EarlyView.Abstract figure legend Left atrial myocytes have TAT‐associated faster Ca2+ release but are more prone to maladaptation at higher frequencies due to weaker peripheral SR Ca2+ uptake and smaller trigger Ca2+ current. Abstract Changes in heart rate affect Ca2+ signalling and contractility in ventricular muscle, but the effects on atrial Ca2+ signalling ...

On the nonuniform Berry--Esseen bound [PDF]
, 2013 Due to the effort of a number of authors, the value c_u of the absolute constant factor in the uniform Berry--Esseen (BE) bound for sums of independent random variables has been gradually reduced to 0.4748 in the iid case and 0.5600 in the general case ...

New beam hardened data correction and its application to artifact reduction in CT images
Medical Physics, Volume 53, Issue 2, February 2026.Abstract Background Beam hardening is an unavoidable phenomenon in polychromatic CT systems, where lower‐energy photons are preferentially absorbed as x‐rays pass through materials such as tissue, bone, and metal. This energy‐dependent attenuation, which conflicts with the monochromatic assumption in filtered back‐projection (FBP), produces artifacts ...
