text: "We construct a perfectly binding string commitment scheme whose security
is based on the learning parity with noise (LPN) assumption, or equivalently,
the hardness of decoding random linear codes. Our scheme not only allows for a
simple and efficient zero-knowledge proof of knowledge for committed values (essentially
a Σ-protocol), but also for such proofs showing any kind of relation amongst committed
values, i.e. proving that messages m_0,...,m_u, are such that m_0=C(m_1,...,m_u)
for any circuit C.\r\n\r\nTo get soundness which is exponentially small in a security
parameter t, and when the zero-knowledge property relies on the LPN problem with
secrets of length l, our 3 round protocol has communication complexity O(t|C|l
log(l)) and computational complexity of O(t|C|l) bit operations. The hidden constants
are small, and the computation consists mostly of computing inner products of
bit-vectors."
acknowledgement: "We are grateful to Petros Mol for helpful discussions on the reduction
for the hardness of the xLPN problem.\r\n"

text: |2-
Gradients of the plant hormone auxin, which depend on its active intercellular transport, are crucial for the maintenance of root meristematic activity. This directional transport is largely orchestrated by a complex interaction of specific influx and efflux carriers that mediate the auxin flow into and out of cells, respectively. Besides these transport proteins, plant-specific polyphenolic compounds knownasflavonols have beenshownto act as endogenous regulators of auxin transport. However, only limited information is available on how flavonol synthesis is developmentally regulated. Using reduction-of-function and overexpression approaches in parallel, we demonstrate that the WRKY23 transcription factor is needed for proper root growth and development by stimulating the local biosynthesis of flavonols. The expression of WRKY23 itself is controlled by auxin through the AUXIN RESPONSE FACTOR 7 (ARF7) and ARF19 transcriptional response pathway. Our results suggest a model in which WRKY23 is part of a transcriptional feedback loop of auxin on its own transport through local regulation of flavonol biosynthesis.

text: Growth and development are coordinated by an array of intercellular communications.
Known plant signaling molecules include phytohormones and hormone peptides. Although
both classes can be implicated in the same developmental processes, little is
known about the interplay between phytohormone action and peptide signaling within
the cellular microenvironment. We show that genes coding for small secretory peptides,
designated GOLVEN (GLV), modulate the distribution of the phytohormone auxin.
The deregulation of the GLV function impairs the formation of auxin gradients
and alters the reorientation of shoots and roots after a gravity stimulus. Specifically,
the GLV signal modulates the trafficking dynamics of the auxin efflux carrier
PIN-FORMED2 involved in root tropic responses and meristem organization. Our work
links the local action of secretory peptides with phytohormone transport. Root
growth factor (RGF) or GOLVEN (GLV) secreted peptides have previously been implicated
in meristem regulation. Whitford et al. now show that RGF/GLV peptides induce
rapid relocalization of the auxin efflux regulator PIN2, regulate auxin gradients,
and modulate auxin-dependent root responses to specific stimuli.

text: Cell polarization via asymmetrical distribution of structures or molecules
is essential for diverse cellular functions and development of organisms, but
how polarity is developmentally controlled has been poorly understood. In plants,
the asymmetrical distribution of the PIN-FORMED (PIN) proteins involved in the
cellular efflux of the quintessential phytohormone auxin plays a central role
in developmental patterning, morphogenesis, and differential growth. Recently
we showed that auxin promotes cell interdigitation by activating the Rho family
ROP GTPases in leaf epidermal pavement cells. Here we found that auxin activation
of the ROP2 signaling pathway regulates the asymmetric distribution of PIN1 by
inhibiting its endocytosis. ROP2 inhibits PIN1 endocytosis via the accumulation
of cortical actin microfilaments induced by the ROP2 effector protein RIC4. Our
findings suggest a link between the developmental auxin signal and polar PIN1
distribution via Rho-dependent cytoskeletal reorganization and reveal the conservation
of a design principle for cell polarization that is based on Rho GTPase-mediated
inhibition of endocytosis.

text: The phytohormone auxin acts as a prominent signal, providing, by its local
accumulation or depletion in selected cells, a spatial and temporal reference
for changes in the developmental program. The distribution of auxin depends on
both auxin metabolism (biosynthesis, conjugation and degradation) and cellular
auxin transport. We identified in silico a novel putative auxin transport facilitator
family, called PIN-LIKES (PILS). Here we illustrate that PILS proteins are required
for auxin-dependent regulation of plant growth by determining the cellular sensitivity
to auxin. PILS proteins regulate intracellular auxin accumulation at the endoplasmic
reticulum and thus auxin availability for nuclear auxin signalling. PILS activity
affects the level of endogenous auxin indole-3-acetic acid (IAA), presumably via
intracellular accumulation and metabolism. Our findings reveal that the transport
machinery to compartmentalize auxin within the cell is of an unexpected molecular
complexity and demonstrate this compartmentalization to be functionally important
for a number of developmental processes.

text: Receptor-mediated endocytosis is an integral part of signal transduction as
it mediates signal attenuation and provides spatial and temporal dimensions to
signaling events. One of the best-studied leucine-rich repeat receptor-like kinases
in plants, BRASSINOSTEROID INSENSITIVE 1 (BRI1), perceives its ligand, the brassinosteroid
(BR) hormone, at the cell surface and is constitutively endocytosed. However,
the importance of endocytosis for BR signaling remains unclear. Here we developed
a bioactive, fluorescent BR analog, Alexa Fluor 647-castasterone (AFCS), and visualized
the endocytosis of BRI1-AFCS complexes in living Arabidopsis thaliana cells. Impairment
of endocytosis dependent on clathrin and the guanine nucleotide exchange factor
for ARF GTPases (ARF-GEF) GNOM enhanced BR signaling by retaining active BRI1-ligand
complexes at the plasma membrane. Increasing the trans-Golgi network/early endosome
pool of BRI1-BR complexes did not affect BR signaling. Our findings provide what
is to our knowledge the first visualization of receptor-ligand complexes in plants
and reveal clathrin-and ARF-GEF-dependent endocytic regulation of BR signaling
from the plasma membrane.

text: 'The directional transport of the phytohormone auxin depends on the phosphorylation
status and polar localization of PIN-FORMED (PIN) auxin efflux proteins. While
PINIOD (PID) kinase is directly involved in the phosphorylation of PIN proteins,
the phosphatase holoenzyme complexes that dephosphorylate PIN proteins remain
elusive. Here, we demonstrate that mutations simultaneously disrupting the function
of Arabidopsis thaliana FyPP1 (for Phytochrome-associated serine/threonine protein
phosphatase1) and FyPP3, two homologous genes encoding the catalytic subunits
of protein phosphatase6 (PP6), cause elevated accumulation of phosphorylated PIN
proteins, correlating with a basal-to-apical shift in subcellular PIN localization.
The changes in PIN polarity result in increased root basipetal auxin transport
and severe defects, including shorter roots, fewer lateral roots, defective columella
cells, root meristem collapse, abnormal cotyledons (small, cup-shaped, or fused
cotyledons), and altered leaf venation. Our molecular, biochemical, and genetic
data support the notion that FyPP1/3, SAL (for SAPS DOMAIN-LIKE), and PP2AA proteins
(RCN1 [for ROOTS CURL IN NAPHTHYLPHTHALAMIC ACID1] or PP2AA1, PP2AA2, and PP2AA3)
physically interact to form a novel PP6-type heterotrimeric holoenzyme complex.
We also show that FyPP1/3, SAL, and PP2AA interact with a subset of PIN proteins
and that for SAL the strength of the interaction depends on the PIN phosphorylation
status. Thus, an Arabidopsis PP6-type phosphatase holoenzyme acts antagonistically
with PID to direct auxin transport polarity and plant development by directly
regulating PIN phosphorylation. '

text: PIN-FORMED (PIN) protein-mediated auxin polar transport is critically important
for development, pattern formation, and morphogenesis in plants. Auxin has been
implicated in the regulation of polar auxin transport by inhibiting PIN endocytosis
[1, 2], but how auxin regulates this process is poorly understood. Our genetic
screen identified the Arabidopsis SPIKE1 (SPK1) gene whose loss-of-function mutations
increased lateral root density and retarded gravitropic responses, as do pin2
knockout mutations [3]. SPK1 belongs to the conserved DHR2-Dock family of Rho
guanine nucleotide exchange factors [4-6]. The spk1 mutations induced PIN2 internalization
that was not suppressed by auxin, as did the loss-of-function mutations for Rho-like
GTPase from Plants 6 (ROP6)-GTPase or its effector RIC1. Furthermore, SPK1 was
required for auxin induction of ROP6 activation. Our results have established
a Rho GTPase-based auxin signaling pathway that maintains PIN2 polar distribution
to the plasma membrane via inhibition of its internalization in Arabidopsis roots.
Our findings provide new insights into signaling mechanisms that underlie the
regulation of the dynamic trafficking of PINs required for long-distance auxin
transport and that link auxin signaling to PIN-mediated pattern formation and
morphogenesis.

text: The dynamic spatial and temporal distribution of the crucial plant signaling
molecule auxin is achieved by feedback coordination of auxin signaling and intercellular
auxin transport pathways [1, 2]. Developmental roles of auxin have been attributed
predominantly to its effect on transcription; however, an alternative pathway
involving AUXIN BINDING PROTEIN1 (ABP1) has been proposed to regulate clathrin-mediated
endocytosis in roots and Rho-like GTPase (ROP)-dependent pavement cell interdigitation
in leaves [3, 4]. In this study, we show that ROP6 and its downstream effector
RIC1 regulate clathrin association with the plasma membrane for clathrin-mediated
endocytosis, as well as for its feedback regulation by auxin. Genetic analysis
revealed that ROP6/RIC1 acts downstream of ABP1 to regulate endocytosis. This
signaling circuit is also involved in the feedback regulation of PIN-FORMED 1
(PIN1) and PIN2 auxin transporters activity (via its constitutive endocytosis)
and corresponding auxin transport-mediated processes, including root gravitropism
and leave vascular tissue patterning. Our findings suggest that the signaling
module auxin-ABP1-ROP6/RIC1-clathrin-PIN1/PIN2 is a shared component of the feedback
regulation of auxin transport during both root and aerial development.

text: A cell membrane can be considered a liquid-phase plane in which lipids and
proteins theoretically are free to diffuse. Numerous reports,however, describe
retarded diffusion ofmembrane proteins in animal cells. This anomalous diffusion
results from a combination of structuring factors including protein-protein interactions,
cytoskeleton corralling, and lipid organization into microdomains. In plant cells,
plasma-membrane (PM) proteins have been described as relatively immobile, but
the control mechanisms that structure the PM have not been studied. Here, we use
fluorescence recovery after photobleaching to estimate mobility of a set of minimal
PM proteins. These proteins consist only of a PM-anchoring domain fused to a fluorescent
protein, but their mobilities remained limited, as is the case for many full-length
proteins. Neither the cytoskeleton nor membrane microdomain structure was involved
in constraining the diffusion of these proteins. The cell wall, however, was shown
to have a crucial role in immobilizing PM proteins. In addition, by single-molecule
fluorescence imaging we confirmed that the pattern of cellulose deposition in
the cell wall affects the trajectory and speed ofPMprotein diffusion. Regulation
ofPMprotein dynamics by the plant cell wall can be interpreted as a mechanism
for regulating protein interactions in processes such as trafficking and signal
transduction.

text: Auxin is a key coordinative signal required for many aspects of plant development
and its levels are controlled by auxin metabolism and intercellular auxin transport.
Here we find that a member of PIN auxin transporter family, PIN8 is expressed
in male gametophyte of Arabidopsis thaliana and has a crucial role in pollen development
and functionality. Ectopic expression in sporophytic tissues establishes a role
of PIN8 in regulating auxin homoeostasis and metabolism. PIN8 co-localizes with
PIN5 to the endoplasmic reticulum (ER) where it acts as an auxin transporter.
Genetic analyses reveal an antagonistic action of PIN5 and PIN8 in the regulation
of intracellular auxin homoeostasis and gametophyte as well as sporophyte development.
Our results reveal a role of the auxin transport in male gametophyte development
in which the distinct actions of ER-localized PIN transporters regulate cellular
auxin homoeostasis and maintain the auxin levels optimal for pollen development
and pollen tube growth.

text: 'We consider the offset-deconstruction problem: Given a polygonal shape Q
with n vertices, can it be expressed, up to a tolerance ε in Hausdorff distance,
as the Minkowski sum of another polygonal shape P with a disk of fixed radius?
If it does, we also seek a preferably simple-looking solution P; then, P''s offset
constitutes an accurate, vertex-reduced, and smoothened approximation of Q. We
give an O(nlogn)-time exact decision algorithm that handles any polygonal shape,
assuming the real-RAM model of computation. A variant of the algorithm, which
we have implemented using the cgal library, is based on rational arithmetic and
answers the same deconstruction problem up to an uncertainty parameter δ its running
time additionally depends on δ. If the input shape is found to be approximable,
this algorithm also computes an approximate solution for the problem. It also
allows us to solve parameter-optimization problems induced by the offset-deconstruction
problem. For convex shapes, the complexity of the exact decision algorithm drops
to O(n), which is also the time required to compute a solution P with at most
one more vertex than a vertex-minimal one.'

text: We consider the problem of minimizing a function represented as a sum of submodular
terms. We assume each term allows an efficient computation of exchange capacities.
This holds, for example, for terms depending on a small number of variables, or
for certain cardinality-dependent terms. A naive application of submodular minimization
algorithms would not exploit the existence of specialized exchange capacity subroutines
for individual terms. To overcome this, we cast the problem as a submodular flow
(SF) problem in an auxiliary graph in such a way that applying most existing SF
algorithms would rely only on these subroutines. We then explore in more detail
Iwata's capacity scaling approach for submodular flows (Iwata 1997 [19]). In particular,
we show how to improve its complexity in the case when the function contains cardinality-dependent
terms.

text: We present a method for recovering a temporally coherent, deforming triangle
mesh with arbitrarily changing topology from an incoherent sequence of static
closed surfaces. We solve this problem using the surface geometry alone, without
any prior information like surface templates or velocity fields. Our system combines
a proven strategy for triangle mesh improvement, a robust multi-resolution non-rigid
registration routine, and a reliable technique for changing surface mesh topology.
We also introduce a novel topological constraint enforcement algorithm to ensure
that the output and input always have similar topology. We apply our technique
to a series of diverse input data from video reconstructions, physics simulations,
and artistic morphs. The structured output of our algorithm allows us to efficiently
track information like colors and displacement maps, recover velocity information,
and solve PDEs on the mesh as a post process.

text: "We present an approach for artist-directed animation of liquids using multiple
levels of control over the simulation, ranging from the overall tracking of desired
shapes to highly detailed secondary effects such as dripping streams, separating
sheets of fluid, surface waves and ripples. The first portion of our technique
is a volume preserving morph that allows the animator to produce a plausible fluid-like
motion from a sparse set of control meshes. By rasterizing the resulting control
meshes onto the simulation grid, the mesh velocities act as boundary conditions
during the projection step of the fluid simulation. We can then blend this motion
together with uncontrolled fluid velocities to achieve a more relaxed control
over the fluid that captures natural inertial effects. Our method can produce
highly detailed liquid surfaces with control over sub-grid details by using a
mesh-based surface tracker on top of a coarse grid-based fluid simulation. We
can create ripples and waves on the fluid surface attracting the surface mesh
to the control mesh with spring-like forces and also by running a wave simulation
over the surface mesh. Our video results demonstrate how our control scheme can
be used to create animated characters and shapes that are made of water.\r\n"

text: We introduce a strategy based on Kustin-Miller unprojection that allows us
to construct many hundreds of Gorenstein codimension 4 ideals with 9 × 16 resolutions
(that is, nine equations and sixteen first syzygies). Our two basic games are
called Tom and Jerry; the main application is the biregular construction of most
of the anticanonically polarised Mori Fano 3-folds of Altinok's thesis. There
are 115 cases whose numerical data (in effect, the Hilbert series) allow a Type
I projection. In every case, at least one Tom and one Jerry construction works,
providing at least two deformation families of quasismooth Fano 3-folds having
the same numerics but different topology. © 2012 Copyright Foundation Compositio

text: Voltage-activated Ca(2+) channels (VACCs) mediate Ca(2+) influx to trigger
action potential-evoked neurotransmitter release, but the mechanism by which Ca(2+)
regulates spontaneous transmission is unclear. We found that VACCs are the major
physiological triggers for spontaneous release at mouse neocortical inhibitory
synapses. Moreover, despite the absence of a synchronizing action potential, we
found that spontaneous fusion of a GABA-containing vesicle required the activation
of multiple tightly coupled VACCs of variable type.

text: 'Since Darwin''s pioneering research on plant reproductive biology (e.g. Darwin
1877), understanding the mechanisms maintaining the diverse sexual strategies
of plants has remained an important challenge for evolutionary biologists. In
some species, populations are sexually polymorphic and contain two or more mating
morphs (sex phenotypes). Differences in morphology or phenology among the morphs
influence patterns of non-random mating. In these populations, negative frequency-dependent
selection arising from disassortative (intermorph) mating is usually required
for the evolutionary maintenance of sexual polymorphism, but few studies have
demonstrated the required patterns of non-random mating. In the current issue
of Molecular Ecology, Shang (2012) make an important contribution to our understanding
of how disassortative mating influences sex phenotype ratios in Acer pictum subsp.
mono (painted maple), a heterodichogamous, deciduous tree of eastern China. They
monitored sex expression in 97 adults and used paternity analysis of open-pollinated
seed to examine disassortative mating among three sex phenotypes. Using a deterministic
''pollen transfer'' model, Shang et al. present convincing evidence that differences
in the degree of disassortative mating in progeny arrays of the sex phenotypes
can explain their uneven frequencies in the adult population. This study provides
a useful example of how the deployment of genetic markers, demographic monitoring
and modelling can be integrated to investigate the maintenance of sexual diversity
in plants. '

text: We introduce the idea of using an explicit triangle mesh to track the air/fluid
interface in a smoothed particle hydrodynamics (SPH) simulator. Once an initial
surface mesh is created, this mesh is carried forward in time using nearby particle
velocities to advect the mesh vertices. The mesh connectivity remains mostly unchanged
across time-steps; it is only modified locally for topology change events or for
the improvement of triangle quality. In order to ensure that the surface mesh
does not diverge from the underlying particle simulation, we periodically project
the mesh surface onto an implicit surface defined by the physics simulation. The
mesh surface gives us several advantages over previous SPH surface tracking techniques.
We demonstrate a new method for surface tension calculations that clearly outperforms
the state of the art in SPH surface tension for computer graphics. We also demonstrate
a method for tracking detailed surface information (like colors) that is less
susceptible to numerical diffusion than competing techniques. Finally, our temporally-coherent
surface mesh allows us to simulate high-resolution surface wave dynamics without
being limited by the particle resolution of the SPH simulation.
