AIM: The accurate mapping of forest carbon stocks is essential for understanding the global carbon cycle, for assessing emissions from deforestation, and for rational land-use planning. Remote sensing (RS) is currently the key tool for this purpose, but RS...

The role of nano-perovskite in the negligible thorium release in seawater from Greek bauxite residue (red mud).

Scientific reports

Gamaletsos PN, Godelitsas A, Kasama T, Kuzmin A, Lagos M, Mertzimekis TJ, Göttlicher J, Steininger R, Xanthos S, Pontikes Y, Angelopoulos GN, Zarkadas C, Komelkov A, Tzamos E, Filippidis A.

We present new data about the chemical and structural characteristics of bauxite residue (BR) from Greek Al industry, using a combination of microscopic, analytical, and spectroscopic techniques. SEM-EDS indicated a homogeneous dominant "Al-Fe-Ca-Ti-Si-Na-Cr matrix", appearing at the microscale. The...

Mobile genetic elements

McCullers TJ, Steiniger M.

Mob Genet Elements. 2017 Apr 19;7(3):1-18. doi: 10.1080/2159256X.2017.1318201. eCollection 2017.

Transposable elements (TEs) are mobile genetic elements that can mobilize within host genomes. As TEs comprise more than 40% of the human genome and are linked to numerous diseases, understanding their mechanisms of mobilization and regulation is important.

Rigorously modeling self-stabilizing fault-tolerant circuits: An ultra-robust clocking scheme for systems-on-chip.

We present the first implementation of a distributed clock generation scheme for Systems-on-Chip that recovers from an unbounded number of arbitrary transient faults despite a large number of arbitrary permanent faults. We devise self-stabilizing hardware building blocks and a...

While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few 'hyperdominant' species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing more carbon...

Discrimination between discrete and continuum scattering from the sub-seafloor.

The Journal of the Acoustical Society of America

Holland CW, Steininger G, Dosso SE.
PMID: 26328684
J Acoust Soc Am. 2015 Aug;138(2):663-73. doi: 10.1121/1.4923451.

There is growing evidence that seabed scattering is often dominated by heterogeneities within the sediment volume as opposed to seafloor roughness. From a theoretical viewpoint, sediment volume heterogeneities can be described either by a fluctuation continuum or by discrete...

Estimating seabed scattering mechanisms via Bayesian model selection.

The Journal of the Acoustical Society of America

Steininger G, Dosso SE, Holland CW, Dettmer J.
PMID: 25324059
J Acoust Soc Am. 2014 Oct;136(4):1552-62. doi: 10.1121/1.4892752.

A quantitative inversion procedure is developed and applied to determine the dominant scattering mechanism (surface roughness and/or volume scattering) from seabed scattering-strength data. The classification system is based on trans-dimensional Bayesian inversion with the deviance information criterion used to...
