Assessing soil water repellency of a sandy field with visible near infrared spectroscopy
(Scopus, 2015)
Soil water repellency (WR) is a widespread phenomenon caused by aggregated organic matter (OM) and layers of hydrophobic organic
substances coating the surface of soil particles. These substances have a very low surface ...

Crioconservación de especies leñosas
(Instituto Tecnológico de Costa Rica, 2015)
La crioconservación (almacenamiento a ultra bajas temperaturas, nitrógeno líquido, NL, -196ºC) fue evaluada en tres especies leñosas de interés comercial: pilón (Hyeronima alchorneoides), especie de gran valor por su rápido ...
A WDM-Compatible 4 × 32-Gb/s CMOS-driven electro-absorption modulator array
(OSA - The Optical Society, 2015)
A four-channel electro-absorption-modulator array, driven by 32-nm CMOS drivers providing 2-V peak-to-peak output swing, operates with BER < 10-12 at a data rate of 4 × 32 Gb/s and dissipates 170 mW of power.
Application of block matrix theory to obtain the inverse transform of the vector-valued DFT
(Hikari Ltd., 2015)
We study the vector-valued discrete Fourier transform (vector-valued DFT) and its inverse transform, the vector-valued DFT inversion, through its block matrix representation. These transforms are defined for N- periodic ...
