  text: Adaptation in the retina is thought to optimize the encoding of natural light
    signals into sequences of spikes sent to the brain. While adaptive changes in
    retinal processing to the variations of the mean luminance level and second-order
    stimulus statistics have been documented before, no such measurements have been
    performed when higher-order moments of the light distribution change. We therefore
    measured the ganglion cell responses in the tiger salamander retina to controlled
    changes in the second (contrast), third (skew) and fourth (kurtosis) moments of
    the light intensity distribution of spatially uniform temporally independent stimuli.
    The skew and kurtosis of the stimuli were chosen to cover the range observed in
    natural scenes. We quantified adaptation in ganglion cells by studying linear-nonlinear
    models that capture well the retinal encoding properties across all stimuli. We
    found that the encoding properties of retinal ganglion cells change only marginally
    when higher-order statistics change, compared to the changes observed in response
    to the variation in contrast. By analyzing optimal coding in LN-type models, we
    showed that neurons can maintain a high information rate without large dynamic
    adaptation to changes in skew or kurtosis. This is because, for uncorrelated stimuli,
    spatio-temporal summation within the receptive field averages away non-gaussian
    aspects of the light intensity distribution.

  text: 'Cu2ZnSnS4, based on abundant and environmental friendly elements and with
    a direct band gap of 1.5 eV, is a main candidate material for solar energy conversion
    through both photovoltaics and photocatalysis. We detail here the synthesis of
    quasi-spherical Cu 2ZnSnS4 nanoparticles with unprecedented narrow size distributions.
    We further detail their use as seeds to produce CZTS-Au and CZTS-Pt heterostructured
    nanoparticles. Such heterostructured nanoparticles are shown to have excellent
    photocatalytic properties toward degradation of Rhodamine B and hydrogen generation
    by water splitting. '

  text: "Bi2S3-xTex bulk nanocomposites with crystal domain sizes in the range from
    50 nm to 100 nm were obtained from the reaction of Bi2S3 nanorods with Te powder.
    The thermoelectric properties of the obtained nanocomposites were analysed in
    the temperature range from 0°C to 300°C. We observed how the thermoelectric properties
    of the material improved with the annealing temperature, being a spark plasma
    sintering process needed to maintain the material nanostructuration while maximising
    its electrical properties. Finally thermoelectric dimensionless figures of merit
    ZT up to 0.42 were obtained before any charge carrier concentration optimisation.

  text: 'Thermoelectricity is a key technology with the potential to improve the efficiency
    of energy conversion processes, which may strongly benefit from advances in the
    field of nanotechnology. Nanostructured materials are very appealing for thermoelectric
    applications, but the full development of their potential requires precise control
    of their properties at the nanoscale. Bottom-up assembly of nanoparticles provides
    access to a three-dimensional composition control at the nanoscale not attainable
    in any other technology. In particular, colloidal nanoheterostructures are especially
    interesting building blocks for the bottom-up production of functional nanomaterials.
    In the present work, we use PbTe@PbS core-shell nanoparticles as building blocks
    for the bottom-up production of PbTe-PbS nanocomposites. We used a ligand exchange
    strategy and a hot press process to promote the electrical conductivity of the
    nanocomposite and to increase its density. These two approaches allowed us to
    improve the performance of bottom-up assembled PbTe-PbS bulk nanostructured materials. '

  text: Herein, a colloidal synthetic route to produce highly monodisperse Cu2HgGeSe4
    (CHGSe) nanoparticles (NPs) is presented in detail. The high yield of the developed
    procedure allowed the production of CHGSe NPs at the gram scale. A thorough analysis
    of their structural and optical properties is shown. CHGSe NPs displayed poly-tetrahedral
    morphology and narrow size distributions with average size in the range of 10–40
    nm and size dispersions below 10 %. A 1.6 eV optical band gap was measured by
    mean of UV–Vis. By adjusting the cation ratio, an effective control of their electrical
    conductivity is achieved. The prepared NPs are used as building blocks for the
    production of CHGSe bulk nanostructured materials. The thermoelectric properties
    of CHGSe nanomaterials are studied in the temperature range from 300 to 730 K.
    CHGSe nanomaterials reached electrical conductivities up to 5 × 104 S m−1, Seebeck
    coefficients above 100 μV K−1, and thermal conductivities below 1.0 W m−1 K−1
    which translated into thermoelectric figures of merit up to 0.34 at 730 K.

  text: 'We report on the photocatalytic hydrogen evolution under full-arc light irradiation
    of CuIn1-xGaxS2 wurtzite nanocrystals in the presence of SO3 2- and S2- as sacrificial
    reagents. We analyzed the hydrogen generation rate as a function of the Ga content
    and associated it with the energy band positions. For photocatalytic water splitting,
    the CuInS2 bandgap is slightly too low to efficiently overcome the reaction over-potential.
    The presence of Ga shifts up the CuInS2 conduction band edge providing a larger
    driving force for photogenerated carriers to activate the water splitting reduction
    reaction. The larger the Ga content, the more energetically favorable the electron
    injection, and thus a more efficient use of the photogenerated carriers is reached.
    However, the band gap increase associated with the Ga incorporation reduces the
    concentration of photogenerated carriers available for water splitting, and consequently
    a lower hydrogen conversion rate is obtained for very high Ga contents. The optimum
    Ga concentration was experimentally found at CuIn0.3Ga0.7S2. '

  text: Cu2ZnSnS4, based on abundant and environmental friendly elements and with
    a direct band gap of 1.5 eV, is a main candidate material for solar energy conversion
    through both photovoltaics and photocatalysis. We detail here the synthesis of
    quasi-spherical Cu 2ZnSnS4 nanoparticles with unprecedented narrow size distributions.
    We further detail their use as seeds to produce CZTS-Au and CZTS-Pt heterostructured
    nanoparticles. Such heterostructured nanoparticles are shown to have excellent
    photocatalytic properties toward degradation of Rhodamine B and hydrogen generation
    by water splitting.

  text: 'Near-resonant Raman scattering measurements of zinc sulfide nanoparticles
    and thin films have been made and correlated to grain and particle size, respectively,
    using a 325 nm wavelength excitation source. The area ratios between the first,
    second, and third order peaks of ZnS identified as the T 2(LO) mode decrease with
    increasing ZnS grain size. This is an effect attributed to changes in the bandgap
    energy from quantum confinement due to the varying grain size between the films/particles,
    as noted by a shift in the room temperature photoluminescence emission corresponding
    to the free exciton emission energy. While Raman scattering spectroscopy is typically
    limited to identification of phases and their crystalline properties, it is possible
    to attain more than such straightforward information by calibrating the spectral
    features to variations between sets of samples. These results open the possibility
    of making a quantitative grain size estimation in ZnS thin films and nanostructures,
    as well as in other material systems where ZnS may be expected as a secondary
    phase, such as Cu2ZnSnS4. Additionally, more commonly used excitation wavelengths
    for Raman scattering, such as 514 and 532 nm, are shown to be of limited use in
    characterizing ZnS thin films due to the extremely low Raman scattering efficiency
    of ZnS in films with sub-micron thicknesses. '

  text: Monodispersed Pt3Sn nanoparticles were prepared through a mild thermal synthesis
    in the presence of surfactants. The performance of Pt3Sn for the electrooxidation
    of ethanol and adsorbed carbon monoxide (COad) in acid medium was studied by a
    combination of electrochemical and insitu spectroscopic methods, namely, infrared
    reflection absorption spectroscopy and differential electrochemical mass spectrometry
    (DEMS), and the results were compared to those obtained with the use of Pt black.
    The formation of the Pt3Sn solid solution promoted the oxidation of COad at less-positive
    potentials than those required for Pt black. Also, the electrooxidation of ethanol,
    especially at lower potentials, was more favorable with Pt3Sn, as deduced from
    the higher faradaic currents recorded during the ethanol oxidation reaction (EOR).
    However, the distribution of products as deduced by DEMS analysis suggested that
    the formation of C1 products, CO2 inclusive, is less significant on Pt3Sn than
    on Pt. In fact, the higher faradaic current recorded with the former catalyst
    can be attributed to the greater amounts of acetaldehyde and acetic acid formed.
    After the EOR, the surface of both Pt and Pt3Sn remained covered by ethanol adsorbates.
    Whereas C2 fragments were the main adsorbates at the surface of Pt3Sn after the
    EOR, both C1 and C2 species remained adsorbed at Pt black.

  text: An appropriate way of realizing property nanoengineering in complex quaternary
    chalcogenide nanocrystals is presented for Cu2Cd xSnSey(CCTSe) polypods. The pivotal
    role of the polarity in determining morphology, growth, and the polytypic branching
    mechanism is demonstrated. Polarity is considered to be responsible for the formation
    of an initial seed that takes the form of a tetrahedron with four cation-polar
    facets. Size and shape confinement of the intermediate pentatetrahedral seed is
    also attributed to polarity, as their external facets are anion-polar. The final
    polypod extensions also branch out as a result of a cation-polarity-driven mechanism.
    Aberration-corrected scanning transmission electron microscopy is used to identify
    stannite cation ordering, while ab initio studies are used to show the influence
    of cation ordering/distortion, stoichiometry, and polytypic structural change
    on the electronic band structure.

  text: We introduce algorithms for the computation of homology, cohomology, and related
    operations on cubical cell complexes, using the technique based on a chain contraction
    from the original chain complex to a reduced one that represents its homology.
    This work is based on previous results for simplicial complexes, and uses Serre’s
    diagonalization for cubical cells. An implementation in C++ of the introduced
    algorithms is available at http://www.pawelpilarczyk.com/chaincon/ together with
    some examples. The paper is self-contained as much as possible, and is written
    at a very elementary level, so that basic knowledge of algebraic topology should
    be sufficient to follow it.

  text: Invasive alien parasites and pathogens are a growing threat to biodiversity
    worldwide, which can contribute to the extinction of endemic species. On the Galápagos
    Islands, the invasive parasitic fly Philornis downsi poses a major threat to the
    endemic avifauna. Here, we investigated the influence of this parasite on the
    breeding success of two Darwin's finch species, the warbler finch (Certhidea olivacea)
    and the sympatric small tree finch (Camarhynchus parvulus), on Santa Cruz Island
    in 2010 and 2012. While the population of the small tree finch appeared to be
    stable, the warbler finch has experienced a dramatic decline in population size
    on Santa Cruz Island since 1997. We aimed to identify whether warbler finches
    are particularly vulnerable during different stages of the breeding cycle. Contrary
    to our prediction, breeding success was lower in the small tree finch than in
    the warbler finch. In both species P. downsi had a strong negative impact on breeding
    success and our data suggest that heavy rain events also lowered the fledging
    success. On the one hand parents might be less efficient in compensating their
    chicks' energy loss due to parasitism as they might be less efficient in foraging
    on days of heavy rain. On the other hand, intense rainfalls might lead to increased
    humidity and more rapid cooling of the nests. In the case of the warbler finch
    we found that the control of invasive plant species with herbicides had a significant
    additive negative impact on the breeding success. It is very likely that the availability
    of insects (i.e. food abundance) is lower in such controlled areas, as herbicide
    usage led to the removal of the entire understory. Predation seems to be a minor
    factor in brood loss.

  text: 'First cycle games (FCG) are played on a finite graph by two players who push
    a token along the edges until a vertex is repeated, and a simple cycle is formed.
    The winner is determined by some fixed property Y of the sequence of labels of
    the edges (or nodes) forming this cycle. These games are traditionally of interest
    because of their connection with infinite-duration games such as parity and mean-payoff
    games. We study the memory requirements for winning strategies of FCGs and certain
    associated infinite duration games. We exhibit a simple FCG that is not memoryless
    determined (this corrects a mistake in Memoryless determinacy of parity and mean
    payoff games: a simple proof by Bj⋯orklund, Sandberg, Vorobyov (2004) that claims
    that FCGs for which Y is closed under cyclic permutations are memoryless determined).
    We show that θ (n)! memory (where n is the number of nodes in the graph), which
    is always sufficient, may be necessary to win some FCGs. On the other hand, we
    identify easy to check conditions on Y (i.e., Y is closed under cyclic permutations,
    and both Y and its complement are closed under concatenation) that are sufficient
    to ensure that the corresponding FCGs and their associated infinite duration games
    are memoryless determined. We demonstrate that many games considered in the literature,
    such as mean-payoff, parity, energy, etc., satisfy these conditions. On the complexity
    side, we show (for efficiently computable Y) that while solving FCGs is in PSPACE,
    solving some families of FCGs is PSPACE-hard. '

  text: Energy games belong to a class of turn-based two-player infinite-duration
    games played on a weighted directed graph. It is one of the rare and intriguing
    combinatorial problems that lie in NP∩co-NP, but are not known to be in P. The
    existence of polynomial-time algorithms has been a major open problem for decades
    and apart from pseudopolynomial algorithms there is no algorithm that solves any
    non-trivial subclass in polynomial time. In this paper, we give several results
    based on the weight structures of the graph. First, we identify a notion of penalty
    and present a polynomial-time algorithm when the penalty is large. Our algorithm
    is the first polynomial-time algorithm on a large class of weighted graphs. It
    includes several worst-case instances on which previous algorithms, such as value
    iteration and random facet algorithms, require at least sub-exponential time.
    Our main technique is developing the first non-trivial approximation algorithm
    and showing how to convert it to an exact algorithm. Moreover, we show that in
    a practical case in verification where weights are clustered around a constant
    number of values, the energy game problem can be solved in polynomial time. We
    also show that the problem is still as hard as in general when the clique-width
    is bounded or the graph is strongly ergodic, suggesting that restricting the graph
    structure does not necessarily help.

  text: Transgenerational effects are broader than only parental relationships. Despite
    mounting evidence that multigenerational effects alter phenotypic and life-history
    traits, our understanding of how they combine to determine fitness is not well
    developed because of the added complexity necessary to study them. Here, we derive
    a quantitative genetic model of adaptation to an extraordinary new environment
    by an additive genetic component, phenotypic plasticity, maternal and grandmaternal
    effects. We show how, at equilibrium, negative maternal and negative grandmaternal
    effects maximize expected population mean fitness. We define negative transgenerational
    effects as those that have a negative effect on trait expression in the subsequent
    generation, that is, they slow, or potentially reverse, the expected evolutionary
    dynamic. When maternal effects are positive, negative grandmaternal effects are
    preferred. As expected under Mendelian inheritance, the grandmaternal effects
    have a lower impact on fitness than the maternal effects, but this dual inheritance
    model predicts a more complex relationship between maternal and grandmaternal
    effects to constrain phenotypic variance and so maximize expected population mean
    fitness in the offspring.
