text: This article refers to algorithms based on finite difference schemes for computing
mean and affine curvature evolutions of digital images, introduced by Alvarez
and Morel [L. Alvarez, J.M. Morel, “Formalization and computational aspects of
image analysis”, Acta Numerica, pp. 159, 1994]. We discuss consistency, stability
and convergence. Our analysis focuses on some possible choices of the parameters,
choices that generate multiple variants in the implementations. Meaningful visual
examples on how the algorithms actually work are provided.

text: "In the present paper we give a thorough analysis of two finite difference
schemes for the Mean Curvature Motion and its affine variant, the Affine Morphological
Scale Space, schemes introduced in the Image Processing framework. This analysis
brings in a series of parameters that allow us to compute an accurate discrete
evolution of curvature motions.\r\nThe choice of these parameters is based on
intrinsic geometric properties of the evolution equations for linear, radial and
elliptical functions. In the last part we present several examples, underlining
the main advantages of the algorithms (the removal of pixelization effects and
JPEG artifacts) as well as their major drawbacks (absence of contrast invariance
and grid dependence). A detailed explanatory report, the ANSI C implementations
and an on-line demo can be found at http://www.ipol.im/."

text: Iron is a ubiquitous impurity in metamict (radiation-damaged and partially
amorphized) materials such as titanite (CaSiTiO5). Using 57Fe Mössbauer spectroscopy
we find that iron in metamict titanite is partitioned between amorphous and crystalline
regions based on valence. Trivalent iron exists in the crystalline titanite matrix
whereas divalent iron exists almost exclusively in radiation-amorphized regions.
We find that the relative abundances of the oxidation states correlate with the
volume fraction of amorphous and crystalline regions. Our data also show that
oxidation of iron proceeds along with the recrystallization of the amorphized
regions. Recrystallization is confirmed to occur over the range 700 °C < T < 925 °C,
and no further structural changes are observed at higher temperatures. It is surprising
that our Mössbauer measurements show divalent iron to be surrounded by titanite
with a high degree of short-range structural order in the amorphized regions.
This observation is fundamentally different from other metamict materials such
as zircon (ZrSiO4), where amorphized regions show no short-range order.

text: Pb, Te, Ag and Se, when reacted in a 1:1:x:1 (x = 1.9, 2.0, 2.01) molar ratio,
form a two phase composite which consists of a phase which crystallizes in the
fcc cubic PbSe structure and a phase that crystallizes in the Ag2Te structure.
In this article, we demonstrate that by varying the Ag concentration, we can manipulate
which variant of the Ag2Te structure stabilizes at room temperature (monoclinic
α-Ag2Te or cubic β-Ag1.9Te) and can consequently manipulate the electrical and
thermal transport behavior of the composite and hence the thermoelectric performance.
Additionally, we show that Cu-doping results in an overall improvement in thermoelectric
performance. Our results suggest that formation of composites is a viable path
for achieving a phonon-glass-electron-crystal (PGEC) alloy.

text: 'Li-ion batteries have transformed portable electronics and will play a key
role in the electrification of transport. However, the highest energy storage
possible for Li-ion batteries is insufficient for the long-term needs of society,
for example, extended-range electric vehicles. To go beyond the horizon of Li-ion
batteries is a formidable challenge; there are few options. Here we consider two:
Li–air (O2) and Li–S. The energy that can be stored in Li–air (based on aqueous
or non-aqueous electrolytes) and Li–S cells is compared with Li-ion; the operation
of the cells is discussed, as are the significant hurdles that will have to be
overcome if such batteries are to succeed. Fundamental scientific advances in
understanding the reactions occurring in the cells as well as new materials are
key to overcoming these obstacles. The potential benefits of Li–air and Li–S justify
the continued research effort that will be needed.'

text: 'The electrolyte is one of the greatest challenges facing the development
of the non‐aqueous Li–O2 battery. Although ether‐based electrolytes do from Li2O2
on the first discharge, it is shown by various techniques that they also decompose
and that decomposition increases while Li2O2 decreases on cycling (see picture).
Thus, these electrolytes are not suitable. '

text: The nonaqueous rechargeable lithium–O2 battery containing an alkyl carbonate
electrolyte discharges by formation of C3H6(OCO2Li)2, Li2CO3, HCO2Li, CH3CO2Li,
CO2, and H2O at the cathode, due to electrolyte decomposition. Charging involves
oxidation of C3H6(OCO2Li)2, Li2CO3, HCO2Li, CH3CO2Li accompanied by CO2 and H2O
evolution. Mechanisms are proposed for the reactions on discharge and charge.
The different pathways for discharge and charge are consistent with the widely
observed voltage gap in Li–O2 cells. Oxidation of C3H6(OCO2Li)2 involves terminal
carbonate groups leaving behind the OC3H6O moiety that reacts to form a thick
gel on the Li anode. Li2CO3, HCO2Li, CH3CO2Li, and C3H6(OCO2Li)2 accumulate in
the cathode on cycling correlating with capacity fading and cell failure. The
latter is compounded by continuous consumption of the electrolyte on each discharge.

text: Lithium-metal oxides with a high formal Li2O content, such as Li5FeO4 (5Li2O•Fe2O3)
and a Li2MnO3•LiFeO2 composite ({Li2O•MnO2}•{Li2O•Fe2O3}) have been explored as
electrocatalysts for primary and rechargeable Li-O2 cells. Activation occurs predominantly
by Li2O removal, either electrochemically or chemically by acid-treatment. Superior
electrochemical behavior is obtained if activation occurs by acid-treatment; Li2MnO3•LiFeO2
catalysts provide 2516 mAh/g (carbon) corresponding to 931 mAh/g (electrocatalyst
+ carbon) during the initial discharge. The reaction is reasonably reversible
during the early cycles. The approach has implications for designing electrocatalysts
that participate through electrochemical Li2O extraction/reformation reactions,
offering exceptionally high capacities.

text: Segmentation is the process of partitioning digital images into meaningful
regions. The analysis of biological high content images often requires segmentation
as a first step. We propose ilastik as an easy-to-use tool which allows the user
without expertise in image processing to perform segmentation and classification
in a unified way. ilastik learns from labels provided by the user through a convenient
mouse interface. Based on these labels, ilastik infers a problem specific segmentation.
A random forest classifier is used in the learning step, in which each pixel's
neighborhood is characterized by a set of generic (nonlinear) features. ilastik
supports up to three spatial plus one spectral dimension and makes use of all
dimensions in the feature calculation. ilastik provides realtime feedback that
enables the user to interactively refine the segmentation result and hence further
fine-tune the classifier. An uncertainty measure guides the user to ambiguous
regions in the images. Real time performance is achieved by multi-threading which
fully exploits the capabilities of modern multi-core machines. Once a classifier
has been trained on a set of representative images, it can be exported and used
to automatically process a very large number of images (e.g. using the CellProfiler
pipeline). ilastik is an open source project and released under the BSD license
at www.ilastik.org.

text: PIN-FORMED (PIN)-dependent auxin transport is essential for plant development
and its modulation in response to the environment or endogenous signals. A NON-PHOTOTROPIC
HYPOCOTYL 3 (NPH3)-like protein, MACCHI-BOU 4 (MAB4), has been shown to control
PIN1 localization during organ formation, but its contribution is limited. The
Arabidopsis genome contains four genes, MAB4/ENP/NPY1-LIKE1 (MEL1), MEL2, MEL3
and MEL4, highly homologous to MAB4. Genetic analysis disclosed functional redundancy
between MAB4 and MEL genes in regulation of not only organ formation but also
of root gravitropism, revealing that NPH3 family proteins have a wider range of
functions than previously suspected. Multiple mutants showed severe reduction
in PIN abundance and PIN polar localization, leading to defective expression of
an auxin responsive marker DR5rev::GFP. Pharmacological analyses and fluorescence
recovery after photo-bleaching experiments showed that mel mutations increase
PIN2 internalization from the plasma membrane, but affect neither intracellular
PIN2 trafficking nor PIN2 lateral diffusion at the plasma membrane. Notably, all
MAB4 subfamily proteins show polar localization at the cell periphery in plants.
The MAB4 polarity was almost identical to PIN polarity. Our results suggest that
the MAB4 subfamily proteins specifically retain PIN proteins in a polarized manner
at the plasma membrane, thus controlling directional auxin transport and plant
development.

text: Endocytosis is a crucial mechanism by which eukaryotic cells internalize extracellular
and plasma membrane material, and it is required for a multitude of cellular and
developmental processes in unicellular and multicellular organisms. In animals
and yeast, the best characterized pathway for endocytosis depends on the function
of the vesicle coat protein clathrin. Clathrinmediated endocytosis has recently
been demonstrated also in plant cells, but its physiological and developmental
roles remain unclear. Here, we assessed the roles of the clathrin-mediated mechanism
of endocytosis in plants by genetic means. We interfered with clathrin heavy chain
(CHC) function through mutants and dominant-negative approaches in Arabidopsis
thaliana and established tools to manipulate clathrin function in a cell type-specific
manner. The chc2 single mutants and dominant-negative CHC1 (HUB) transgenic lines
were defective in bulk endocytosis as well as in internalization of prominent
plasma membrane proteins. Interference with clathrin-mediated endocytosis led
to defects in constitutive endocytic recycling of PIN auxin transporters and their
polar distribution in embryos and roots. Consistent with this, these lines had
altered auxin distribution patterns and associated auxin transport-related phenotypes,
such as aberrant embryo patterning, imperfect cotyledon specification, agravitropic
growth, and impaired lateral root organogenesis. Together, these data demonstrate
a fundamental role for clathrin function in cell polarity, growth, patterning,
and organogenesis in plants.

text: 'Background: Whereas the majority of animals develop toward a predetermined
body plan, plants show iterative growth and continually produce new organs and
structures from actively dividing meristems. This raises an intriguing question:
How are these newly developed organs patterned? In Arabidopsis embryos, radial
symmetry is broken by the bisymmetric specification of the cotyledons in the apical
domain. Subsequently, this bisymmetry is propagated to the root promeristem. Results:
Here we present a mutually inhibitory feedback loop between auxin and cytokinin
that sets distinct boundaries of hormonal output. Cytokinins promote the bisymmetric
distribution of the PIN-FORMED (PIN) auxin efflux proteins, which channel auxin
toward a central domain. High auxin promotes transcription of the cytokinin signaling
inhibitor AHP6, which closes the interaction loop. This bisymmetric auxin response
domain specifies the differentiation of protoxylem in a bisymmetric pattern. In
embryonic roots, cytokinin is required to translate a bisymmetric auxin response
in the cotyledons to a bisymmetric vascular pattern in the root promeristem. Conclusions:
Our results present an interactive feedback loop between hormonal signaling and
transport by which small biases in hormonal input are propagated into distinct
signaling domains to specify the vascular pattern in the root meristem. It is
an intriguing possibility that such a mechanism could transform radial patterns
and allow continuous vascular connections between other newly emerging organs.'

text: The phytohormone auxin is an important determinant of plant development. Directional
auxin flow within tissues depends on polar localization of PIN auxin transporters.
To explore regulation of PIN-mediated auxin transport, we screened for suppressors
of PIN1 overexpression (supo) and identified an inositol polyphosphate 1-phosphatase
mutant (supo1), with elevated inositol trisphosphate (InsP 3) and cytosolic Ca
2+ levels. Pharmacological and genetic increases in InsP 3 or Ca 2+ levels also
suppressed the PIN1 gain-of-function phenotypes and caused defects in basal PIN
localization, auxin transport and auxin-mediated development. In contrast, the
reductions in InsP 3 levels and Ca 2+ signaling antagonized the effects of the
supo1 mutation and disrupted preferentially apical PIN localization. InsP 3 and
Ca 2+ are evolutionarily conserved second messengers involved in various cellular
functions, particularly stress responses. Our findings implicate them as modifiers
of cell polarity and polar auxin transport, and highlight a potential integration
point through which Ca 2+ signaling-related stimuli could influence auxin-mediated
development.

text: The polarized transport of the phytohormone auxin [1], which is crucial for
the regulation of different stages of plant development [2, 3], depends on the
asymmetric plasma membrane distribution of the PIN-FORMED (PIN) auxin efflux carriers
[4, 5]. The PIN polar localization results from clathrin-mediated endocytosis
(CME) from the plasma membrane and subsequent polar recycling [6]. The Arabidopsis
genome encodes two groups of dynamin-related proteins (DRPs) that show homology
to mammalian dynamin - a protein required for fission of endocytic vesicles during
CME [7, 8]. Here we show by coimmunoprecipitation (coIP), bimolecular fluorescence
complementation (BiFC), and Förster resonance energy transfer (FRET) that members
of the DRP1 group closely associate with PIN proteins at the cell plate. Localization
and phenotypic analysis of novel drp1 mutants revealed a requirement for DRP1
function in correct PIN distribution and in auxin-mediated development. We propose
that rapid and specific internalization of PIN proteins mediated by the DRP1 proteins
and the associated CME machinery from the cell plate membranes during cytokinesis
is an important mechanism for proper polar PIN positioning in interphase cells.

text: The phytohormone auxin is vital to plant growth and development. A unique
property of auxin among all other plant hormones is its cell-to-cell polar transport
that requires activity of polarly localized PIN-FORMED (PIN) auxin efflux transporters.
Despite the substantial molecular insight into the cellular PIN polarization,
the mechanistic understanding for developmentally and environmentally regulated
PIN polarization is scarce. The long-standing belief that auxin modulates its
own transport by means of a positive feedback mechanism has inspired both experimentalists
and theoreticians for more than two decades. Recently, theoretical models for
auxin-dependent patterning in plants include the feedback between auxin transport
and the PIN protein localization. These computer models aid to assess the complexity
of plant development by testing and predicting plausible scenarios for various
developmental processes that occur in planta. Although the majority of these models
rely on purely heuristic principles, the most recent mechanistic models tentatively
integrate biologically testable components into known cellular processes that
underlie the PIN polarity regulation. The existing and emerging computational
approaches to describe PIN polarization are presented and discussed in the light
of recent experimental data on the PIN polar targeting.

Plants take up iron from the soil using the IRON-REGULATED TRANSPORTER 1 (IRT1) high-affinity iron transporter at the root surface. Sophisticated regulatory mechanisms allow plants to tightly control the levels of IRT1, ensuring optimal absorption of essential but toxic iron. Here, we demonstrate that overexpression of Arabidopsis thaliana IRT1 leads to constitutive IRT1 protein accumulation, metal overload, and oxidative stress. IRT1 is unexpectedly found in trans-Golgi network/early endosomes of root hair cells, and its levels and localization are unaffected by iron nutrition. Using pharmacological approaches, we show that IRT1 cycles to the plasma membrane to perform iron and metal uptake at the cell surface and is sent to the vacuole for proper turnover. We also prove that IRT1 is monoubiquitinated on several cytosol-exposed residues in vivo and that mutation of two putative monoubiquitination target residues in IRT1 triggers stabilization at the plasma membrane and leads to extreme lethality. Together, these data suggest a model in which monoubiquitin-dependent internalization/sorting and turnover keep the plasma membrane pool of IRT1 low to ensure proper iron uptake and to prevent metal toxicity. More generally, our work demonstrates the existence of monoubiquitin-dependent trafficking to lytic vacuoles in plants and points to proteasome-independent turnover of plasma membrane proteins.

text: Summary Gravitropism aligns plant growth with gravity. It involves gravity
perception and the asymmetric distribution of the phytohormone auxin. Here we
provide insights into the mechanism for hypocotyl gravitropic growth. We show
that the Arabidopsis thaliana PIN3 auxin transporter is required for the asymmetric
auxin distribution for the gravitropic response. Gravistimulation polarizes PIN3
to the bottom side of hypocotyl endodermal cells, which correlates with an increased
auxin response at the lower hypocotyl side. Both PIN3 polarization and hypocotyl
bending require the activity of the trafficking regulator GNOM and the protein
kinase PINOID. Our data suggest that gravity-induced PIN3 polarization diverts
the auxin flow to mediate the asymmetric distribution of auxin for gravitropic
shoot bending.

text: Root system architecture depends on lateral root (LR) initiation that takes
place in a relatively narrow developmental window (DW). Here, we analyzed the
role of auxin gradients established along the parent root in defining this DW
for LR initiation. Correlations between auxin distribution and response, and spatiotemporal
control of LR initiation were analyzed in Arabidopsis thaliana and tomato (Solanum
lycopersicum). In both Arabidopsis and tomato roots, a well defined zone, where
auxin content and response are minimal, demarcates the position of a DW for founder
cell specification and LR initiation. We show that in the zone of auxin minimum
pericycle cells have highest probability to become founder cells and that auxin
perception via the TIR1/AFB pathway, and polar auxin transport, are essential
for the establishment of this zone. Altogether, this study reveals that the same
morphogen-like molecule, auxin, can act simultaneously as a morphogenetic trigger
of LR founder cell identity and as a gradient-dependent signal defining positioning
of the founder cell specification. This auxin minimum zone might represent an
important control mechanism ensuring the LR initiation steadiness and the acropetal
LR initiation pattern. © 2011 The Authors. New Phytologist © 2011 New Phytologist
