Statistical, data-driven methods are considered good alternatives to process-based models for the sub-national monitoring of cereal crop yields, since they can flexibly handle large datasets and can be calibrated simultaneously to different areas.

Comparison of Highbush Blueberry (Vaccinium corymbosum L.) under Ridge and Pot Production
Due to the specific requirements for low soil pH, new production methods are being introduced for highbush blueberry (Vaccinium corymbosum L.). Planting in pots has gained popularity in recent years due to the easier control of the substrate pH.

On a conjecture of Ridge [PDF]
Summary: The conjecture of Ridge on the numerical range of a shift of periodic weights is resolved in the affirmative, i.e., if the weights are nonzero, the numerical range of the corresponding shift is an open disc centered at the origin. The radius of the disc can be expressed as the Perron root of a nonnegative irreducible symmetric matrix.

Grafts for Ridge Preservation [PDF]
Alveolar ridge bone resorption is a biologic phenomenon that occurs following tooth extraction and cannot be prevented. This paper reviews the vertical and horizontal ridge dimensional changes that are associated with tooth extraction. It also provides an overview of the advantages of ridge preservation as well as grafting materials.

Interchannel EEG synchronization, as well as its violation, is an important diagnostic sign of a number of diseases. In particular, during an epileptic seizure, such synchronization occurs starting from some pairs of channels up to many pairs in a ...

AbstractLet X be an n by p matrix, and define RX(λ)=X(X′X+λPX′)-X′, which is called a ridge operator, where λ is a nonnegative constant (called the ridge parameter), and PX′=X′(XX′)-X. Various properties of RX(λ) were discussed, including additive decompositions of this matrix similar to those of PX≡RX(0)=X(X′X)-X′, the orthogonal projector onto the ...

Bose enhancement and the ridge
We point out that Bose enhancement in a hadronic wave function generically leads to correlations between produced particles. We show explicitly, by calculating the projectile density matrix in the Color Glass Condensate approach to high-energy hadronic collisions, that the Bose enhancement of gluons in the projectile leads to azimuthal collimation of ...

Energy and system dependence of high-$p_T$ triggered two-particle near-side correlations [PDF]
Previous studies have indicated that the near-side peak of high-$p_T$ triggered correlations can be decomposed into two parts, the \textit{Jet} and the \textit{Ridge}.

Fluctuations in initial energy density distributions in A + A collisions [PDF]
The analysis of particle correlations as a function of relative pseudo-rapidity and azimuthal angle exhibit novel ridge-like structures that were discovered at RHIC in A + A collisions.
