Abstract:
It is important to understand reflective properties of snow, for
example for remote sensing applications and for modelling of energy
balances in snow packs. We developed a method to calculate the
reflectance of real snow: First, we tomographed snow samples to
acquire snow structure images (6 x 2 mm). Second, we calculated the
sample reflectance by modelling the radiative transfer, using a
beam tracing model. This model calculates the biconical
reflectance (BR) derived from an arbitrary number of incident beams.
The incident beams represent a diffuse light source. We applied
our method to four different snow samples: Fresh snow, metamorphosed
snow, depth hoar, and wet snow. The results show that (i) the
calculated and measured reflectances agree well and (ii) the model
produces different biconical reflectances for different snow
types. The ratio of the structure to the wavelength is large. We
estimated that the size parameter is larger than 50 in all cases we
analysed. Specific surface area of the snow samples explains most
of the difference in radiance, but not the different biconical
reflectance distributions. The presented method overcomes
the limitations of common radiative transfer models which use
idealised grain shapes such as spheres, plates, needles and
hexagonal particles. With this method we could improve
our understanding for changes in biconical reflectance
distribution associated with changes in specific surface area.

Title:
"Bacterial biosensors for measuring availability of environmental pollutants"

Abstract: Traditionally,
pollution risk assessment is based on the measurement of a pollutant’s
total concentration in a sample. The toxicity of a given pollutant in
environment, however, is tightly linked to its bioavailability, which
may differ significantly from the former. Physico-chemical and
biological parameters thus strongly influence the pollutant’s fate in
terms of leaching, sequestration and biodegradation. Bacterial
biosensors, which are micro-organisms genetically engineered for
environmental sensing, offer an interesting alternative to monitoring
approaches based on conventional chemical analyses. They can sense, per
definition, what is bioavailable, thereby providing useful information
for risk assessment. At the present time, a wide variety of
environmental pollutants can be targeted by biosensors. Although many
of them are still confined to the lab, several bacterial biosensors
already proved their utility in field assay, with detection limits
comparable to chemical analysis. This review proposes an overview of
the existing bacterial biosensors, with a specific focus on the concept
of bioavailability.

"Neuromorphic VLSI models of selective attention: from single chip sensors to multi-chip systems"

Abstract: Biological organisms perform
complex selective attention operations continuously and effortlessly.
These operations allow them to quickly determine the motor actions to
take, in response to combinations of external stimuli and internal
states; or to pay attention to subsets of sensory inputs, suppressing
non salient ones; or to plan complex action sequences, serially
choosing elementary behaviors among different alternatives. One of
the main computational primitives used by nature to perform these
selection operations is implemented by Winner-Take-All (WTA) networks.
These networks are formed by arrays of coupled computational elements
that selectively amplify the strongest input signals, while suppressing
the remaining ones. Neuromorphic circuits are an optimal medium for
constructing WTA networks and for implementing efficient hardware
models of selective attention systems. In this paper we present an
overview of selective attention systems based on neuromorphic WTA
circuits ranging from single-chip vision sensors for selecting and
tracking the position of salient features, to a multi-chip system that
implements a saliency-map based model of selective attention.
