Synthesizing SMOS Zero-Baselines with Aquarius Brightness Temperature Simulator [PDF]
, 2012 SMOS [1] and Aquarius [2] are ESA and NASA missions, respectively, to make L-band measurements from the Low Earth Orbit. SMOS makes passive measurements whereas Aquarius measures both passive and active. SMOS was launched in November 2009 and Aquarius in

People and Nature, EarlyView.Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey

An evaluation of SMOS L-band vegetation optical depth (L-VOD) data sets: high sensitivity of L-VOD to above-ground biomass in Africa [PDF]
Biogeosciences, 2018 The vegetation optical depth (VOD) measured at microwave frequencies is related to the vegetation water content and provides information complementary to visible/infrared vegetation indices.

Phytochemical Analysis, EarlyView.ABSTRACT Primary brain tumors are life‐threatening diseases. Glioblastoma is the most aggressive type with a poor prognosis. Medulloblastoma is the most common pediatric brain tumor. While surgical treatments often result in recurrences owing to the complex nature of the tumor microenvironment, conventional treatments lower the quality of life of ...

, 2011 We derive an SMO-like algorithm for the optimization problem arising from the Second Order Cone Programming formulation of support vector machines (SVMs) for classification. Due to the square root term in the objective of the form, we cannot easily compute the location of the extrema using Newton‘s formula.

Validation of SMOS sea ice thickness retrieval in the northern Baltic Sea [PDF]
, 2015 The Soil Moisture and Ocean Salinity (SMOS) mission observes brightness temperatures at a low microwave frequency of 1.4 GHz (L-band) with a daily coverage of the polar regions.

Quarterly Journal of the Royal Meteorological Society, EarlyView.We document for the first time how the assimilation of CS2SMOS observations improves the model representation of Arctic sea‐ice thickness (SIT) and its variability: biases are reduced (top row), while excessive variability in the Beaufort Sea and lack of variability in the ice pack are both corrected (bottom row).

Sliding Mode Control in Aerospace Applications: A Survey
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Organic Agriculture Movement at a Crossroad - a Comparative Study of Denmark and Japan [PDF]
, 2006 Along with apparent institutionalisation of organic agriculture that took place in the last couple of decades, the role of organic agriculture organisations as a social movement actor has increasingly being put into question.
