text: Experimental evidence for the scaling of the finite amplitude of perturbation
theory required to promote transition in Poiseuille flow was found. The exponent
is -1 and was uncovered using considerable care in the design and execution of
the experiment. Interestingly, this exponent was also found in experiments on
transition in boundary layers.

text: Plant growth is marked by its adaptability to continuous changes in environment.
A regulated, differential distribution of auxin underlies many adaptation processes
including organogenesis, meristem patterning and tropisms. In executing its multiple
roles, auxin displays some characteristics of both a hormone and a morphogen.
Studies on auxin transport, as well as tracing the intracellular movement of its
molecular components, have suggested a possible scenario to explain how growth
plasticity is conferred at the cellular and molecular level. The plant perceives
stimuli and changes the subcellular position of auxin-transport components accordingly.
These changes modulate auxin fluxes, and the newly established auxin distribution
triggers the corresponding developmental response.

text: Plants have many polarized cell types, but relatively little is known about
the mechanisms that establish polarity. The orc mutant was identified originally
by defects in root patterning, and positional cloning revealed that the affected
gene encodes STEROL METHYLTRANSFERASE1, which is required for the appropriate
synthesis and composition of major membrane sterols. smt1orc mutants displayed
several conspicuous cell polarity defects. Columella root cap cells revealed perturbed
polar positioning of different organelles, and in the smt1orc root epidermis,
polar initiation of root hairs was more randomized. Polar auxin transport and
expression of the auxin reporter DR5-β-glucuronidase were aberrant in smt1orc.
Patterning defects in smt1orc resembled those observed in mutants of the PIN gene
family of putative auxin efflux transporters. Consistently, the membrane localization
of the PIN1 and PIN3 proteins was disturbed in smt1orc, whereas polar positioning
of the influx carrier AUX1 appeared normal. Our results suggest that balanced
sterol composition is a major requirement for cell polarity and auxin efflux in
Arabidopsis.

text: Plant biology is currently experiencing a growing demand for easy and reliable
mRNA and protein localisation techniques. Here, we present novel whole mount in
situ hybridisation and immunolocalisation protocols, suitable to localise mRNAs
and proteins in Arabidopsis seedlings. We demonstrate that these methods can be
used in different organs of Arabidopsis seedlings as well as in other plant species.
In order to achieve better reproducibility and higher throughput, we modified
these protocols for automation to be performed by a liquid handling robot. In
addition, we show that other procedures such as reporter enzyme assays and tissue
clearing can be similarly automated. We present examples of application of our
protocols including mRNA localisation and proteins and epitope tag (co)localisations
which demonstrate that these methods provide reliable and versatile tools for
expression, localisation and anatomical studies in plants.

text: The regular arrangement of leaves around a plant's stem, called phyllotaxis,
has for centuries attracted the attention of philosophers, mathematicians and
natural scientists; however, to date, studies of phyllotaxis have been largely
theoretical. Leaves and flowers are formed from the shoot apical meristem, triggered
by the plant hormone auxin. Auxin is transported through plant tissues by specific
cellular influx and efflux carrier proteins. Here we show that proteins involved
in auxin transport regulate phyllotaxis. Our data indicate that auxin is transported
upwards into the meristem through the epidermis and the outermost meristem cell
layer. Existing leaf primordia act as sinks, redistributing auxin and creating
its heterogeneous distribution in the meristem. Auxin accumulation occurs only
at certain minimal distances from existing primordia, defining the position of
future primordia. This model for phyllotaxis accounts for its reiterative nature,
as well as its regularity and stability.

Axis formation occurs in plants, as in animals, during early embryogenesis. However, the underlying mechanism is not known. Here we show that the first manifestation of the apical-basal axis in plants, the asymmetric division of the zygote, produces a basal cell that transports and an apical cell that responds to the signalling molecule auxin. This apical-basal auxin activity gradient triggers the specification of apical embryo structures and is actively maintained by a novel component of auxin efflux, PIN7, which is located apically in the basal cell. Later, the developmentally regulated reversal of PIN7 and onset of PIN1 polar localization reorganize the auxin gradient for specification of the basal root pole. An analysis of pin quadruple mutants identifies PIN-dependent transport as an essential part of the mechanism for embryo axis formation. Our results indicate how the establishment of cell polarity, polar auxin efflux and local auxin response result in apical-basal axis formation of the embryo, and thus determine the axiality of the adult plant.

Plants, compared to animals, exhibit an amazing adaptability and plasticity in their development. This is largely dependent on the ability of plants to form new organs, such as lateral roots, leaves, and flowers during postembryonic development. Organ primordia develop from founder cell populations into organs by coordinated cell division and differentiation. Here, we show that organ formation in Arabidopsis involves dynamic gradients of the signaling molecule auxin with maxima at the primordia tips. These gradients are mediated by cellular efflux requiring asymmetrically localized PIN proteins, which represent a functionally redundant network for auxin distribution in both aerial and underground organs. PIN1 polar localization undergoes a dynamic rearrangement, which correlates with establishment of auxin gradients and primordium development. Our results suggest that PIN-dependent, local auxin gradients represent a common module for formation of all plant organs, regardless of their mature morphology or developmental origin.

text: Significant advances have been made during the past few years in our understanding
of how the spinal monosynaptic reflex develops. Transcription factors in the Neurogenin,
Runt, ETS, and LIM families control sequential steps of the specification of various
subtypes of dorsal root ganglia sensory neurons. The initiation of muscle spindle
differentiation requires neuregulin 1, derived from Ia afferent sensory neurons,
and signaling through ErbB receptors in intrafusal muscle fibers. Several retrograde
signals from the periphery are important for the establishment of late connectivity
in the reflex circuit. Finally, neurotrophin 3 released from muscle spindles regulates
the strength of sensory-motor connections within the spinal cord postnatally.

text: Tripartite G-protein-coupled receptors (GPCRs) represent one of the largest
groups of signal transducers, transmitting signals from hormones, neuropeptides,
odorants, food and light. Ligand-bound receptors catalyse GDP/GTP exchange on
the G-protein α-subunit (Gα), leading to α-GTP separation from the βγ subunits
and pathway activation. Activating mutations in the receptors or G proteins underlie
many human diseases, including some cancers, dwarfism and premature puberty. Regulators
of G-protein signalling (RGS proteins) are known to modulate the level and duration
of ligand-induced signalling by accelerating the intrinsic GTPase activity of
the Gα subunit, and thus reformation of the inactive GDP-bound Gα. Here we find
that even in the absence of receptor, mutation of the RGS family member Sst2 (refs
6-9) permits spontaneous activation of the G-protein-coupled mating pathway in
Saccharomyces cerevisiae at levels normally seen only in the presence of ligand.
Our work demonstrates the occurence of spontaneous tripartite G-protein signalling
in vivo and identifies a requirement for RGS proteins in preventing such receptor-independent
activation.

text: Biosynthesis of most peptide hormones and neuropeptides requires proteolytic
excision of the active peptide from inactive proprotein precursors, an activity
carried out by subtilisin-like proprotein convertases (SPCs) in constitutive or
regulated secretory pathways. The Drosophila amontillado (amon) gene encodes a
homolog of the mammalian PC2 protein, an SPC that functions in the regulated secretory
pathway in neuroendocrine tissues. We have identified amon mutants by isolating
ethylmethanesulfonate (EMS)-induced lethal and visible mutations that define two
complementation groups in the amon interval at 97D1 of the third chromosome. DNA
sequencing identified the amon complementation group and the DNA sequence change
for each of the nine amon alleles isolated. amon mutants display partial embryonic
lethality, are defective in larval growth, and arrest during the first to second
instar larval molt. Mutant larvae can be rescued by heat-shock-induced expression
of the amon protein. Rescued larvae arrest at the subsequent larval molt, suggesting
that amon is also required for the second to third instar larval molt. Our data
indicate that the amon proprotein convertase is required during embryogenesis
and larval development in Drosophila and support the hypothesis that AMON acts
to proteolytically process peptide hormones that regulate hatching, larval growth,
and larval ecdysis.

text: Geodesic active contours and graph cuts are two standard image segmentation
techniques. We introduce a new segmentation method combining some of their benefits.
Our main intuition is that any cut on a graph embedded in some continuous space
can be interpreted as a contour (in 2D) or a surface (in 3D). We show how to build
a grid graph and set its edge weights so that the cost of cuts is arbitrarily
close to the length (area) of the corresponding contours (surfaces) for any anisotropic
Riemannian metric. There are two interesting consequences of this technical result.
First, graph cut algorithms can be used to find globally minimum geodesic contours
(minimal surfaces in 3D) under arbitrary Riemannian metric for a given set of
boundary conditions. Second, we show how to minimize metrication artifacts in
existing graph-cut based methods in vision. Theoretically speaking, our work provides
an interesting link between several branches of mathematics -differential geometry,
integral geometry, and combinatorial optimization. The main technical problem
is solved using Cauchy-Crofton formula from integral geometry.

text: 'Reconstructing a 3-D scene from more than one camera is a classical problem
in computer vision. One of the major sources of difficulty is the fact that not
all scene elements are visible from all cameras. In the last few years, two promising
approaches have been developed 11,12 that formulate the scene reconstruction problem
in terms of energy minimization, and minimize the energy using graph cuts. These
energy minimization approaches treat the input images symmetrically, handle visibility
constraints correctly, and allow spatial smoothness to be enforced. However, these
algorithm propose different problem formulations, and handle a limited class of
smoothness terms. One algorithm 11 uses a problem formulation that is restricted
to two-camera stereo, and imposes smoothness between a pair of cameras. The other
algorithm 12 can handle an arbitrary number of cameras, but imposes smoothness
only with respect to a single camera. In this paper we give a more general energy
minimization formulation for the problem, which allows a larger class of spatial
smoothness constraints. We show that our formulation includes both of the previous
approaches as special cases, as well as permitting new energy functions. Experimental
results on real data with ground truth are also included. '

text: We address visual correspondence problems without assuming that scene points
have similar intensities in different views. This situation is common, usually
due to non-lambertian scenes or to differences between cameras. We use maximization
of mutual information, a powerful technique for registering images that requires
no a priori model of the relationship between scene intensities in different views.
However, it has proven difficult to use mutual information to compute dense visual
correspondence. Comparing fixed-size windows via mutual information suffers from
the well-known problems of fixed windows, namely poor performance at discontinuities
and in low-texture regions. In this paper, we show how to compute visual correspondence
using mutual information without suffering from these problems. Using 'a simple
approximation, mutual information can be incorporated into the standard energy
minimization framework used in early vision. The energy can then be efficiently
minimized using graph cuts, which preserve discontinuities and handle low-texture
regions. The resulting algorithm combines the accurate disparity maps that come
from graph cuts with the tolerance for intensity changes that comes from mutual
information.

text: We show that the fixed alphabet shortest common supersequence (SCS) and the
fixed alphabet longest common subsequence (LCS) problems parameterized in the
number of strings are W[1]-hard. Unless W[1]=FPT, this rules out the existence
of algorithms with time complexity of O(f(k)nα) for those problems. Here n is
the size of the problem instance, α is constant, k is the number of strings and
f is any function of k. The fixed alphabet version of the LCS problem is of particular
interest considering the importance of sequence comparison (e.g. multiple sequence
alignment) in the fixed length alphabet world of DNA and protein sequences.

text: 'Luby and Rackoff showed how to construct a (super-)pseudo-random permutation
{0,1}2n→ {0,1}2n from some number r of pseudo-random functions {0,1}n → {0,1}n.
Their construction, motivated by DES, consists of a cascade of r Feistel permutations.
A Feistel permutation 1for a pseudo-random function f is defined as (L, R) → (R,L
⊕ f (R)), where L and R are the left and right part of the input and ⊕ denotes
bitwise XOR or, in this paper, any other group operation on {0,1}n. The only non-trivial
step of the security proof consists of proving that the cascade of r Feistel permutations
with independent uniform random functions {0,1}n → {0,1}n, denoted Ψ2nr is indistinguishable
from a uniform random permutation {0,1}2n → {0,1}2n by any computationally unbounded
adaptive distinguisher making at most O(2cn) combined chosen plaintext/ciphertext
queries for any c < α, where a is a security parameter. Luby and Rackoff proved
α = 1/2 for r = 4. A natural problem, proposed by Pieprzyk is to improve on α
for larger r. The best known result, α = 3/4 for r = 6, is due to Patarin. In
this paper we prove a = 1 -O(1/r), i.e., the trivial upper bound α = 1 can be
approached. The proof uses some new techniques that can be of independent interest. '

text: Neurons can produce action potentials with high temporal precision(1). A fundamental
issue is whether, and how, this capability is used in information processing.
According to the `cell assembly' hypothesis, transient synchrony of anatomically
distributed groups of neurons underlies processing of both external sensory input
and internal cognitive mechanisms(2-4). Accordingly, neuron populations should
be arranged into groups whose synchrony exceeds that predicted by common modulation
by sensory input. Here we find that the spike times of hippocampal pyramidal cells
can be predicted more accurately by using the spike times of simultaneously recorded
neurons in addition to the animals location in space. This improvement remained
when the spatial prediction was refined with a spatially dependent theta phase
modulation(5-8). The time window in which spike times are best predicted from
simultaneous peer activity is 10-30 ms, suggesting that cell assemblies are synchronized
at this timescale. Because this temporal window matches the membrane time constant
of pyramidal neurons(9), the period of the hippocampal gamma oscillation(10) and
the time window for synaptic plasticity(11), we propose that cooperative activity
at this timescale is optimal for information transmission and storage in cortical
circuits.

text: Gamma frequency oscillations (30-100 Hz) have been suggested to underlie various
cognitive and motor functions. Here, we examine the generation of gamma oscillation
currents in the hippocampus, using two-dimensional, 96-site silicon probes. Two
gamma generators were identified, one in the dentate gyrus and another in the
CA3-CA1 regions. The coupling strength between the two oscillators varied during
both theta and nontheta states. Both pyramidal cells and interneurons were phase-locked
to gamma waves. Anatomical connectivity, rather than physical distance, determined
the coupling strength of the oscillating neurons. CA3 pyramidal neurons discharged
CA3 and CA1 interneurons at latencies indicative of monosynaptic connections.
Intrahippocampal gamma oscillation emerges in the CA3 recurrent system, which
entrains the CA1 region via its interneurons.

text: Parallel recording of neuronal activity in the behaving animal is a prerequisite
for our understanding of neuronal representation and storage of information. Here
we describe the development of micro-machined silicon microelectrode arrays for
unit and local field recordings. The two-dimensional probes with 96 or 64 recording
sites provided high-density recording of unit and field activity with minimal
tissue displacement or damage. The on-chip active circuit eliminated movement
and other artifacts and greatly reduced the weight of the headgear. The precise
geometry of the recording tips allowed for the estimation of the spatial location
of the recorded neurons and for high-resolution estimation of extracellular current
source density. Action potentials could be simultaneously recorded from the soma
and dendrites of the same neurons. Silicon technology is a promising approach
for high-density, high-resolution sampling of neuronal activity in both basic
research and prosthetic devices.
