Maximum water stress is decoupled from climate, traits, and growth in a xeric oak. [PDF]

New Phytol
We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

Beyond species means - the intraspecific contribution to global wood density variation. [PDF]

New Phytol
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Identification of Nonlinear Systems Using Radial Basis Function Neural Network [PDF]

, 2014
This paper uses the radial basis function neural network (RBFNN) for system identification of nonlinear systems. Five nonlinear systems are used to examine the activity of RBFNN in system modeling of nonlinear systems; the five nonlinear systems are ...

Radial-Artery or Saphenous-Vein Grafts in Coronary-Artery Bypass Surgery [PDF]

, 2018
BACKGROUND: The use of radial-artery grafts for coronary-artery bypass grafting (CABG) may result in better postoperative outcomes than the use of saphenous-vein grafts.

Orthogonal least squares algorithm for training multi-output radial basis function networks [PDF]

, 1991
A constructive learning algorithm for multioutput radial basis function networks is presented. Unlike most network learning algorithms, which require a fixed network structure, this algorithm automatically determines an adequate radial basis function ...

Use of Long Radial Sheaths for Radial Artery Spasm in Neurointerventions

, 2021
One of the challenges of the radial approach is radial artery spasm. Because of the smaller caliber, the guide catheters can cause significant spasm that can complicate the procedure or even preclude it.
