text: 'ACAP-type ARF GTPase activating proteins (ARF-GAPs) regulate multiple cellular
processes, including endocytosis, secretion, phagocytosis, cell adhesion and cell
migration. However, the regulation of ACAP functions by other cellular proteins
is poorly understood. We have reported previously that a plant ACAP, VAN3, plays
a pivotal role in plant venation continuity. Here, we report on newly identified
VAN3 regulators: the CVP2 (cotyledon vascular pattern 2) 5 PTase, which is considered
to degrade IP3 and also to produce PtdIns(4)P from PtdIns(4,5)P2; and a PH domain-containing
protein, VAB (VAN3 binding protein). Combinational mutations of both CVP2 and
its closest homologue CVL1 (CVP2 like 1) phenocopied the strong allele of van3
mutants, showing severe vascular continuity. The phenotype of double mutants between
van3, cvp2 and vab suggested that VAN3, CVP2 and VAB function in vascular pattern
formation in the same pathway. Localization analysis revealed that both CVP2 and
VAB colocalize with VAN3 in the trans- Golgi network (TGN), supporting their functions
in the same pathway. The subcellular localization of VAN3 was dependent on its
PH domain, and mislocalization of VAN3 was induced in cvp2 or vab mutants. These
results suggest that CVP2 and VAB cooperatively regulate the subcellular localization
of VAN3 through the interaction between its PH domain and phosphoinositides and/or
inositol phosphates. In addition, PtdIns(4)P, to which VAN3 binds preferentially,
enhanced the ARF-GAP activity of VAN3, whereas IP3 inhibited it. These results
suggest the existence of PtdIns(4)P and/or IP3-dependent subcellular targeting
and regulation of VAN3 ACAP activity that governs plant vascular tissue continuity.'

text: Local hormone maxima are essential for the development of multicellular structures
and organs. For example, steroid hormones accumulate in specific cell types of
the animal fetus to induce sexual differentiation and concentration peaks of the
plant hormone auxin direct organ initiation and mediate tissue patterning. Here
we provide an example of a regulated local hormone minimum required during organogenesis.
Our results demonstrate that formation of a local auxin minimum is necessary for
specification of the valve margin separation layer where Arabidopsis fruit opening
takes place. Consequently, ectopic production of auxin, specifically in valve
margin cells, leads to a complete loss of proper cell fate determination. The
valve margin identity factor INDEHISCENT (IND) is responsible for forming the
auxin minimum by coordinating auxin efflux in separation-layer cells. We propose
that the simplicity of formation and maintenance make local hormone minima particularly
well suited to specify a small number of cells such as the stripes at the valve
margins.

text: The differential distribution of the plant signaling molecule auxin is required
for many aspects of plant development. Local auxin maxima and gradients arise
as a result of local auxin metabolism and, predominantly, from directional cell-to-cell
transport. In this primer, we discuss how the coordinated activity of several
auxin influx and efflux systems, which transport auxin across the plasma membrane,
mediates directional auxin flow. This activity crucially contributes to the correct
setting of developmental cues in embryogenesis, organogenesis, vascular tissue
formation and directional growth in response to environmental stimuli.

text: The plant signalling molecule auxin provides positional informa-tion in a
variety of developmental processes by means of its differential distribution (gradients)
within plant tissues. Thus, cellular auxin levels often determine the developmental
output of auxin signalling. Conceptually, transmembrane transport and metabolic
processes regulate the steady-state levels of auxin in any given cell2,3. In particular,
PIN auxin-efflux-carrier-mediated, directional transport between cells is crucial
for generating auxin gradients2,4,5. Here we show that Arabidopsis thaliana PIN5,
an atypical member of the PIN gene family, encodes a functional auxin transporter
that is required for auxin-mediated develop-ment. PIN5 does not have a direct
role in cell-to-cell transport but regulates intracellular auxin homeostasis and
metabolism. PIN5 localizes, unlike other characterized plasma membrane PIN proteins,
to endoplasmic reticulum (ER), presumably medi-ating auxin flow from the cytosol
to the lumen of the ER. The ER localization of other PIN5-like transporters (including
the moss PIN) indicates that the diversification of PIN protein functions in mediating
auxin homeostasis at the ER, and cell-to-cell auxin transport at the plasma membrane,
represent an ancient event during the evolution of land plants.

text: The phytohormone auxin plays a major role in embryonic and postembryonic plant
development. The temporal and spatial distribution of auxin largely depends on
the subcellular polar localization of members of the PIN-FORMED (PIN) auxin efflux
carrier family. The Ser/Thr protein kinase PINOID (PID) catalyzes PIN phosphorylation
and crucially contributes to the regulation of apical-basal PIN polarity. The
GTP exchange factor on ADP-ribosylation factors (ARF-GEF), GNOM preferentially
mediates PIN recycling at the basal side of the cell. Interference with GNOM activity
leads to dynamic PIN transcytosis between different sides of the cell. Our genetic,
pharmacological, and cell biological approaches illustrate that PID and GNOM influence
PIN polarity and plant development in an antagonistic manner and that the PID-dependent
PIN phosphorylation results in GNOM-independent polar PIN targeting. The data
suggest that PID and the protein phosphatase 2A not only regulate the static PIN
polarity, but also act antagonistically on the rate of GNOM-dependent polar PIN
transcytosis. We propose a model that includes PID-dependent PIN phosphorylation
at the plasma membrane and the subsequent sorting of PIN proteins to a GNOM-independent
pathway for polarity alterations during developmental processes, such as lateral
root formation and leaf vasculature development.

text: The PIN-FORMED (PIN) proteins are secondary transporters acting in the efflux
of the plant signal molecule auxin from cells. They are asymmetrically localized
within cells and their polarity determines the directionality of intercellular
auxin flow. PIN genes are found exclusively in the genomes of multicellular plants
and play an important role in regulating asymmetric auxin distribution in multiple
developmental processes, including embryogenesis, organogenesis, tissue differentiation
and tropic responses. All PIN proteins have a similar structure with amino- and
carboxy-terminal hydrophobic, membrane-spanning domains separated by a central
hydrophilic domain. The structure of the hydrophobic domains is well conserved.
The hydrophilic domain is more divergent and it determines eight groups within
the protein family. The activity of PIN proteins is regulated at multiple levels,
including transcription, protein stability, subcellular localization and transport
activity. Different endogenous and environmental signals can modulate PIN activity
and thus modulate auxin-distribution-dependent development. A large group of PIN
proteins, including the most ancient members known from mosses, localize to the
endoplasmic reticulum and they regulate the subcellular compartmentalization of
auxin and thus auxin metabolism. Further work is needed to establish the physiological
importance of this unexpected mode of auxin homeostasis regulation. Furthermore,
the evolution of PIN-based transport, PIN protein structure and more detailed
biochemical characterization of the transport function are important topics for
further studies.

text: 'We investigate the transferability of an enhanced temperature-index melt
model that was developed and tested on Haut Glacier d’Arolla, Switzerland, in
the 2001 season. The model’s empirical parameters (temperature factor, TF, and
shortwave radiation factor, SRF) are recalibrated for: (1) other locations on
Haut Glacier d’Arolla; (2) subperiods of distinct meteorological conditions; (3)
different years on Haut Glacier d’Arolla; and (4) other glaciers in different
years. The model parameters are optimized against simulations of an energy-balance
model validated against ablation observations. Results are compared with those
obtained with the original parameters. The model works very well when applied
to other sites, seasons and glaciers, with the exception of overcast conditions.
Differences are due to underestimation of high melt rates. The parameter values
are associated with the prevailing energy-balance conditions, showing that high
SRF are obtained on clear-sky days, whereas higher TF are typical of locations
where glacier winds prevail and turbulent fluxes are high. We also provide a range
of parameters clearly associated with the site’s location and its meteorological
characteristics that could help to assign parameter values to sites where few
data are available.'

text: We discuss the inclusion of the subsurface heat-conduction flux into the calculation
of the energy balance and ablation at the glacier–atmosphere interface. Data from
automatic weather stations are used to force an energy-balance model at several
locations on alpine glaciers and at one site in the dry Andes of central Chile.
The heat-conduction flux is computed using a two-layer scheme, assuming that 36%
of the net shortwave radiation is absorbed by the surface layer and that the rest
penetrates into the snowpack. We compare simulations conducted with and without
subsurface heat flux. Results show that assuming a surface temperature of zero
degrees leads to a larger overestimation of melt at the sites in the accumulation
area (10.4–13.3%) than in the ablation area (0.5–2.8%), due to lower air temperatures
and the presence of snow. The difference between simulations with and without
heat conduction is also high at the beginning and end of the ablation season (up
to 29% for the first 15 days of the season), when air temperatures are lower and
snow covers the glacier surface, while they are of little importance during periods
of sustained melt at all the locations investigated.

text: 'The nervous system of seeing animals derives information about optic flow
in two subsequent steps. First, local motion vectors are calculated from moving
retinal images, and second, the spatial distribution of these vectors is analyzed
on the dendrites of large downstream neurons. In dipteran flies, this second step
relies on a set of motion-sensitive lobula plate tangential cells (LPTCs), which
have been studied in great detail in large fly species. Yet, studies on neurons
that convey information to LPTCs and neuroanatomical investigations that enable
a mechanistic understanding of the underlying dendritic computations in LPTCs
are rare. We investigated the subcellular distribution of nicotinic acetylcholine
receptors (nAChRs) on two sets of LPTCs: vertical system (VS) and horizontal system
(HS) cells in Drosophila melanogaster. In this paper, we describe that both cell
types express Dα7-type nAChR subunits specifically on higher order dendritic branches,
similar to the expression of gamma aminobutyric acid (GABA) receptors. These findings
support a model in which directional selectivity of LPTCs is achieved by the dendritic
integration of excitatory, cholinergic, and inhibitory GABA-ergic input from local
motion detectors with opposite preferred direction. Nonetheless, whole-cell recordings
in mutant flies without Dα7 nAChRs revealed that direction selectivity of VS and
HS cells is largely retained. In addition, mutant LPTCs were responsive to acetylcholine
and remaining nAChR receptors were labeled by α-bungarotoxin. These results in
LPTCs with genetically manipulated excitatory input synapses suggest a robust
cellular implementation of dendritic processing that warrants direction selectivity.
The underlying mechanism that ensures appropriate nAChR-mediated synaptic currents
and the functional implications of separate sets or heteromultimeric nAChRs can
now be addressed in this system.'

text: 'This paper introduces a data-driven representation and modeling technique
for simulating non-linear heterogeneous soft tissue. It simplifies the construction
of convincing deformable models by avoiding complex selection and tuning of physical
material parameters, yet retaining the richness of non-linear heterogeneous behavior.
We acquire a set of example deformations of a real object, and represent each
of them as a spatially varying stress-strain relationship in a finite-element
model. We then model the material by non-linear interpolation of these stress-strain
relationships in strain-space. Our method relies on a simple-to-build capture
system and an efficient run-time simulation algorithm based on incremental loading,
making it suitable for interactive computer graphics applications. We present
the results of our approach for several non-linear materials and biological soft
tissue, with accurate agreement of our model to the measured data. '

text: The crystal structure of d(CACACG)·d(CGTGTG) was solved to a resolution of
2.05 Å in space group P21. The duplex assumes the left-handed Z-DNA structure.
The presence of two A·T base pairs in the hexamer does not greatly affect the
conformation. The most significant changes compared with the regular structure
of Z-DNA are in the values of twist in the central portion of the helix. This
variation, as well as others in the values of roll, inclination etc., follow the
pattern observed previously in the structure of d(CGCACG)·d(CGTGCG).

text: 'Let (E, H, μ) be an abstract Wiener space and let DV : = V D, where D denotes
the Malliavin derivative and V is a closed and densely defined operator from H
into another Hilbert space under(H, {combining low line}). Given a bounded operator
B on under(H, {combining low line}), coercive on the range over(R (V), -), we
consider the operators A : = V* B V in H and under(A, {combining low line}) :
= V V* B in under(H, {combining low line}), as well as the realisations of the
operators L : = DV* B DV and under(L, {combining low line}) : = DV DV* B in Lp
(E, μ) and Lp (E, μ ; under(H, {combining low line})) respectively, where 1 <
p < ∞. Our main result asserts that the following four assertions are equivalent:
(1)D (sqrt(L)) = D (DV) with {norm of matrix} sqrt(L) f {norm of matrix}p {minus
tilde} {norm of matrix} DV f {norm of matrix}p for f ∈ D (sqrt(L));(2)under(L,
{combining low line}) admits a bounded H∞-functional calculus on over(R (DV),
-);(3)D (sqrt(A)) = D (V) with {norm of matrix} sqrt(A) h {norm of matrix} {minus
tilde} {norm of matrix} V h {norm of matrix} for h ∈ D (sqrt(A));(4)under(A, {combining
low line}) admits a bounded H∞-functional calculus on over(R (V), -). Moreover,
if these conditions are satisfied, then D (L) = D (DV2) ∩ D (DA). The equivalence
(1)-(4) is a non-symmetric generalisation of the classical Meyer inequalities
of Malliavin calculus (where under(H, {combining low line}) = H, V = I, B = frac(1,
2) I). A one-sided version of (1)-(4), giving Lp-boundedness of the Riesz transform
DV / sqrt(L) in terms of a square function estimate, is also obtained. As an application
let -A generate an analytic C0-contraction semigroup on a Hilbert space H and
let -L be the Lp-realisation of the generator of its second quantisation. Our
results imply that two-sided bounds for the Riesz transform of L are equivalent
with the Kato square root property for A. The boundedness of the Riesz transform
is used to obtain an Lp-domain characterisation for the operator L.'

text: The local atomic structure of PbTiO3, BaTiO3, and KNbO3 perovskite-type crystals
and K x Na1 − x NbO3 solid solutions in different phases is investigated using
the angular dependence of the pre-edge structure of the Ti and Nb K X-ray absorption
spectra and the EXAFS data. In noncubic phases, a considerable deviation of the
local structure from the structure determined from diffraction data is observed
only for the tetragonal phase of the BaTiO3 crystal. It is revealed that, in the
cubic phase of niobates, the niobium atoms are characterized by significant displacements
from the centrosymmetric positions along the threefold axes, so that they are
close in the magnitude and the direction to the displacements in the low-temperatures
rhombohedral phases.

text: Relying on the quantization rule of Raab and Friedrich [Phys. Rev. A (2009)
in press], we derive simple and accurate formulae for the number of rotational
states supported by a weakly bound vibrational level of a diatomic molecular ion.
We also provide analytic estimates of the rotational constants of any such levels
up to threshold for dissociation and obtain a criterion for determining whether
a given weakly bound vibrational level is rotationless. The results depend solely
on the long-range part of the molecular potential.

text: We investigate the effects of a magnetic field on the dynamics of rotationally
inelastic collisions of open-shell molecules (Σ2, Σ3, and Π2) with closed-shell
atoms. Our treatment makes use of the Fraunhofer model of matter wave scattering
and its recent extension to collisions in electric [M. Lemeshko and B. Friedrich,
J. Chem. Phys. 129, 024301 (2008)] and radiative fields [M. Lemeshko and B. Friedrich,
Int. J. Mass. Spec. 280, 19 (2009)]. A magnetic field aligns the molecule in the
space-fixed frame and thereby alters the effective shape of the diffraction target.
This significantly affects the differential and integral scattering cross sections.
We exemplify our treatment by evaluating the magnetic-field-dependent scattering
characteristics of the He-CaH (XΣ+2), He-O2 (XΣ–3), and He-OH (XΠΩ2) systems at
thermal collision energies. Since the cross sections can be obtained for different
orientations of the magnetic field with respect to the relative velocity vector,
the model also offers predictions about the frontal-versus-lateral steric asymmetry
of the collisions. The steric asymmetry is found to be almost negligible for the
He-OH system, weak for the He-CaH collisions, and strong for the He-O2. While
odd ΔM transitions dominate the He-OH [J=3/2,f→J′,e/f] integral cross sections
in a magnetic field parallel to the relative velocity vector, even ΔM transitions
prevail in the case of the He-CaH (X2Σ+) and He-O2 (XΣ−3) collision systems. For
the latter system, the magnetic field opens inelastic channels that are closed
in the absence of the field. These involve the transitions N=1,J=0→N′, J′ with
J′=N′.

text: We examine the effects of a linearly polarized nonresonant radiative field
on the dynamics of rotationally inelastic Na+ + N2 collisions at eV collision
energies. Our treatment is based on the Fraunhofer model of matter wave scattering
and its recent extension to collisions in electric fields [M. Lemeshko, B. Friedrich,
J. Chem. Phys. 129 (2008) 024301]. The nonresonant radiative field changes the
effective shape of the target molecule by aligning it in the space-fixed frame.
This markedly alters the differential and integral scattering cross-sections.
As the cross-sections can be evaluated for a polarization of the radiative field
collinear or perpendicular to the relative velocity vector, the model also offers
predictions about steric asymmetry of the collisions.

text: Numerical modelling of the deformation of a polymer using the finite elements
method in axisymetrical mode was performed using the LsDyna® software to describe
the filling of micro-cavities during the forming process of the material using
the hot embossing. These simulations firstly allow verifying whether the chosen
forming process conditions promote or not an optimized filling of the superficial
cavities in order to achieve precise replicas which best reproduce the superficial
topography of the mould. The simulations were carried out to evaluate the filling
of the cavities taking into account the mechanical behaviour of the selected polymer
into the model. Moreover, these models were developed to verify the effect of
the distribution of the mould cavities on their filling. The influence of the
mobility of non deformable rigid plates on the filling of the cavities represents
an auxiliary variable. In the approach presented, the compression plates are assumed
to be parallel and non deformable, whereas the polymer disk follows a rubbery
behaviour around a temperature equal to 140°C. Globally the modelling results
are satisfactory for they are rather close to the experimental observations conducted.
In summary, the effect of the normal stress as also the distribution of micro-cavities
at the mould surface seem to prevail in the case of the forming process by hot
embossing.

text: "This paper describes observations and metrological analyses made to compare
the replication quality of polymeric replicas obtained by filling micro-cavities
using both hot embossing and micro-injection moulding processes. The experiments
are performed with polypropylene (PP) at a constant melt temperature and a constant
mould temperature, whereas hot embossing tests are carried out with the same polymer
at temperatures close to the softening one.\r\nThe results concerning the micro-cavities
filling provide information on the reliability about the possibilities of replication
topographical surface geometries. The data obtained by scanning mechanical microscopy
(SMM) are used to determine the comparative filling ratio values."

text: 'By making use of the quantization rule of Raab and Friedrich [Phys. Rev.
A 78, 022707 (2008)], we derive simple and accurate formulae for the number of
rotational states supported by a weakly bound vibrational level of a diatomic
molecule and the rotational constants of any such levels up to the threshold,
and provide a criterion for determining whether a given weakly bound vibrational
level is rotationless. The results depend solely on the long-range part of the
molecular potential and are applicable to halo molecules. '
