text: Cells in a developing embryo have no direct way of "measuring" their
physical position. Through a variety of processes, however, the expression levels
of multiple genes come to be correlated with position, and these expression levels
thus form a code for "positional information." We show how to measure
this information, in bits, using the gap genes in the Drosophila embryo as an
example. Individual genes carry nearly two bits of information, twice as much
as expected if the expression patterns consisted only of on/off domains separated
by sharp boundaries. Taken together, four gap genes carry enough information to
define a cell's location with an error bar of ~1% along the anterior-posterior
axis of the embryo. This precision is nearly enough for each cell to have a unique
identity, which is the maximum information the system can use, and is nearly constant
along the length of the embryo. We argue that this constancy is a signature of
optimality in the transmission of information from primary morphogen inputs to
the output of the gap gene network.

text: We report a procedure to prepare highly monodisperse copper telluride nanocubes,
nanoplates, and nanorods. The procedure is based on the reaction of a copper salt
with trioctylphosphine telluride in the presence of lithium bis(trimethylsilyl)amide
and oleylamine. CuTe nanocrystals display a strong near-infrared optical absorption
associated with localized surface plasmon resonances. We exploit this plasmon
resonance for the design of surface-enhanced Raman scattering sensors for unconventional
optical probes. Furthermore, we also report here our preliminary analysis of the
use of CuTe nanocrystals as cytotoxic and photothermal agents.

text: 'We consider Markov decision processes (MDPs) with Büchi (liveness) objectives.
We consider the problem of computing the set of almost-sure winning states from
where the objective can be ensured with probability 1. Our contributions are as
follows: First, we present the first subquadratic symbolic algorithm to compute
the almost-sure winning set for MDPs with Büchi objectives; our algorithm takes
O(n · √ m) symbolic steps as compared to the previous known algorithm that takes
O(n 2) symbolic steps, where n is the number of states and m is the number of
edges of the MDP. In practice MDPs have constant out-degree, and then our symbolic
algorithm takes O(n · √ n) symbolic steps, as compared to the previous known O(n
2) symbolic steps algorithm. Second, we present a new algorithm, namely win-lose
algorithm, with the following two properties: (a) the algorithm iteratively computes
subsets of the almost-sure winning set and its complement, as compared to all
previous algorithms that discover the almost-sure winning set upon termination;
and (b) requires O(n · √ K) symbolic steps, where K is the maximal number of edges
of strongly connected components (scc''s) of the MDP. The win-lose algorithm requires
symbolic computation of scc''s. Third, we improve the algorithm for symbolic scc
computation; the previous known algorithm takes linear symbolic steps, and our
new algorithm improves the constants associated with the linear number of steps.
In the worst case the previous known algorithm takes 5×n symbolic steps, whereas
our new algorithm takes 4×n symbolic steps.'

text: The bottom-up assembly of nanocrystals provides access to a three-dimensional
composition control at the nanoscale not attainable by any other technology. In
particular, colloidal nanoheterostructures, with intrinsic multiphase organization,
are especially appealing building blocks for the bottom-up production of nanocomposites.
In the present work, we use PbTe-PbS as the model material system and thermoelectricity
as the paradigmatic application to investigate the potential of the bottom-up
assembly of core-shell nanoparticles to produce functional nanocomposites. With
this goal in mind, a rapid, high-yield and scalable colloidal synthetic route
to prepare grams of PbTe@PbS core-shell nanoparticles with unprecedented narrow
size distributions and exceptional composition control is detailed. PbTe@PbS nanoparticles
were used as building blocks for the bottom-up production of PbTe-PbS nanocomposites
with tuned composition. In such PbTe-PbS nanocomposites, synergistic nanocrystal
doping effects result in up to 10-fold higher electrical conductivities than in
pure PbTe and PbS nanomaterials. At the same time, the acoustic impedance mismatch
between PbTe and PbS phases and a partial phase alloying provide PbTe-PbS nanocomposites
with strongly reduced thermal conductivities. As a result, record thermoelectric
figures of merit (ZT) of ∼1.1 were obtained from undoped PbTe and PbS phases at
710 K. These high ZT values prove the potential of the proposed processes to produce
efficient functional nanomaterials with programmable properties. © 2013 American

text: 'A multistrategy approach to overcome the main challenges of nanoparticle-based
solution-processed Cu2ZnSnSe4 thin film solar cells is presented. We developed
an efficient ligand exchange strategy, using an antimony salt, to displace organic
ligands from the surface of Cu 2ZnSnS4 nanoparticles. An automated pulsed spray-deposition
system was used to deposit the nanoparticles into homogeneous and crack-free films
with controlled thickness. After annealing the film in a Se-rich atmosphere, carbon-free
and crystalline Cu2ZnSnSe4 absorber layers were obtained. Not only was crystallization
promoted by the complete removal of organics, but also Sb itself played a critical
role. The Sb-assisted crystal growth is associated with the formation of a Sb-based
compound at the grain boundaries, which locally reduces the melting point, thus
promoting the film diffusion-limited crystallization. '

text: We report a procedure to prepare highly monodisperse copper telluride nanocubes,
nanoplates, and nanorods. The procedure is based on the reaction of a copper salt
with trioctylphosphine telluride in the presence of lithium bis(trimethylsilyl)amide
and oleylamine. CuTe nanocrystals display a strong near-infrared optical absorption
associated with localized surface plasmon resonances. We exploit this plasmon
resonance for the design of surface-enhanced Raman scattering sensors for unconventional
optical probes. Furthermore, we also report here our preliminary analysis of the
use of CuTe nanocrystals as cytotoxic and photothermal agents.

text: The compositional versatility of I2–II–IV–VI4 tetrahedrally-coordinated compounds
allows for accommodating their functional properties to numerous technological
applications. Among them, Cu2ZnSnSe4 is an emerging photovoltaic material and
Cu2CdSnSe4 displays excellent thermoelectric properties. The third compound of
this family, Cu2HgSnSe4, remains relatively unexplored. Herein, a synthetic route
to produce Cu2HgSnSe4 nanoparticles with narrow size distribution and controlled
composition is presented. Cu2HgSnSe4 nanoparticles were subsequently used as building
blocks to produce bulk nanocrystalline materials, whose thermoelectric properties
were analyzed. A very preliminary adjustment of the material composition yielded
Seebeck coefficients up to 160 μV K−1, electrical conductivities close to 104
S m−1 and thermal conductivities down to 0.5 W m−1 K−1.

text: Understanding the relative importance of heterosis and outbreeding depression
over multiple generations is a key question in evolutionary biology and is essential
for identifying appropriate genetic sources for population and ecosystem restoration.
Here we use 2455 experimental crosses between 12 population pairs of the rare
perennial plant Rutidosis leptorrhynchoides (Asteraceae) to investigate the multi-generational
(F1, F2, F3) fitness outcomes of inter-population hybridization. We detected no
evidence of outbreeding depression, with inter-population hybrids and backcrosses
showing either similar fitness or significant heterosis for fitness components
across the three generations. Variation in heterosis among population pairs was
best explained by characteristics of the foreign source or home population, and
was greatest when the source population was large, with high genetic diversity
and low inbreeding, and the home population was small and inbred. Our results
indicate that the primary consideration for maximizing progeny fitness following
population augmentation or restoration is the use of seed from large, genetically
diverse populations.
