text: Auxin is a multifunctional hormone essential for plant development and pattern
formation. A nuclear auxin-signaling system controlling auxin-induced gene expression
is well established, but cytoplasmic auxin signaling, as in its coordination of
cell polarization, is unexplored. We found a cytoplasmic auxin-signaling mechanism
that modulates the interdigitated growth of Arabidopsis leaf epidermal pavement
cells (PCs), which develop interdigitated lobes and indentations to form a puzzle-piece
shape in a two-dimensional plane. PC interdigitation is compromised in leaves
deficient in either auxin biosynthesis or its export mediated by PINFORMED 1 localized
at the lobe tip. Auxin coordinately activates two Rho GTPases, ROP2 and ROP6,
which promote the formation of complementary lobes and indentations, respectively.
Activation of these ROPs by auxin occurs within 30 s and depends on AUXIN-BINDING
PROTEIN 1. These findings reveal Rho GTPase-based auxin-signaling mechanisms,
which modulate the spatial coordination of cell expansion across a field of cells.

text: Rapid advances in the field of plant biology, especially in plant cell biology,
have created the need for methods that allow the localization of proteins in situ
at subcellular resolution. Although in many cases recombinant proteins with fluorescent
proteins can fulfill this task, antibody-based immunological detection of proteins
is a complementary technique, which avoids the risk of inducing side effects by
a fusion protein, such as misexpression, mistargeting, altered stability, or toxicity.
Moreover, recombinant protein techniques are applicable only to a rather limited
set of model plants. The immunolocalization protocols presented here can be used
to display protein localization patterns in different tissues of various plant
species. This chapter describes a whole mount immunolocalization protocol, which
has been extensively used in Arabidopsis roots and some above-ground tissues,
and that also works in other species. Additionally, for bulky or hard tissue types,
a variation of this protocol for paraffin-embedded sections is given.

text: Plant development is exceptionally flexible as manifested by its potential
for organogenesis and regeneration, which are processes involving rearrangements
of tissue polarities. Fundamental questions concern how individual cells can polarize
in a coordinated manner to integrate into the multicellular context. In canalization
models, the signaling molecule auxin acts as a polarizing cue, and feedback on
the intercellular auxin flow is key for synchronized polarity rearrangements.
We provide a novel mechanistic framework for canalization, based on up-to-date
experimental data and minimal, biologically plausible assumptions. Our model combines
the intracellular auxin signaling for expression of PINFORMED (PIN) auxin transporters
and the theoretical postulation of extracellular auxin signaling for modulation
of PIN subcellular dynamics. Computer simulations faithfully and robustly recapitulated
the experimentally observed patterns of tissue polarity and asymmetric auxin distribution
during formation and regeneration of vascular systems and during the competitive
regulation of shoot branching by apical dominance. Additionally, our model generated
new predictions that could be experimentally validated, highlighting a mechanistically
conceivable explanation for the PIN polarization and canalization of the auxin
flow in plants.

text: Auxin is an essential plant-specific regulator of patterning processes that
also controls directional growth of roots and shoots. In response to gravity stimulation,
the PIN3 auxin transporter polarizes to the bottomside of gravity-sensing root
cells, presumably redirecting the auxin flux toward the lower side of the root
and triggering gravitropic bending. By combining live-cell imaging techniques
with pharmacological and genetic approaches, we demonstrate that PIN3 polarization
does not require secretion of de novo synthesized proteins or protein degradation,
but instead involves rapid, transient stimulation of PIN endocytosis, presumably
via a clathrin-dependent pathway. Moreover, gravity-induced PIN3 polarization
requires the activity of the guanine nucleotide exchange factors for ARF GTPases
(ARF-GEF) GNOM-dependent polar-targeting path-ways and might involve endosome-based
PIN3 translocation from one cell side to another. Our data suggest that gravity
perception acts at several instances of PIN3 trafficking, ultimately leading to
the polarization of PIN3, which presumably aligns auxin fluxes with gravity vector
and mediates downstream root gravitropic response.

text: Endocytosis is crucial for various cellular functions and development of multicellular
organisms. In mammals and yeast, ADP-ribosylation factor (ARF) GTPases, key components
of vesicle formation, and their regulators ARF-guanine nucleotide exchange factors
(GEFs) and ARF-GTPase-activating protein (GAPs) mediate endocytosis. A similar
role has not been established in plants,mainly because of the lack of the canonical
ARF and ARF-GEF components that are involved in endocytosis in other eukaryotes.
In this study, we revealed a regulatory mechanism of endocytosis in plants based
on ARF GTPase activity.Weidentified that ARF-GEFGNOMand ARF-GAP VASCULAR NETWORK
DEFECTIVE 3 (VAN3), both of which are involved in polar auxin transport-dependent
morphogenesis, localize at the plasma membranes as well as in intracellular structures.
Variable angle epifluorescence microscopy revealed that GNOM and VAN3 localize
to partially overlapping discrete foci at the plasmamembranes that are regularly
associated with the endocytic vesicle coat clathrin. Genetic studies revealed
that GNOM and VAN3 activities are required for endocytosis and internalization
of plasma membrane proteins, including PIN-FORMED auxin transporters. These findings
identified ARF GTPase-based regulatory mechanisms for endocytosis in plants. GNOMand
VAN3 previously were proposed to function solely at the recycling endosomes and
trans-Golgi networks, respectively. Therefore our findings uncovered an additional
cellular function of these prominent developmental regulators.

text: The four microsporangia of the flowering plant anther develop from archesporial
cells in the L2 of the primordium. Within each microsporangium, developing microsporocytes
are surrounded by concentric monolayers of tapetal, middle layer and endothecial
cells. How this intricate array of tissues, each containing relatively few cells,
is established in an organ possessing no formal meristems is poorly understood.
We describe here the pivotal role of the LRR receptor kinase EXCESS MICROSPOROCYTES
1 (EMS1) in forming the monolayer of tapetal nurse cells in Arabidopsis. Unusually
for plants, tapetal cells are specified very early in development, and are subsequently
stimulated to proliferate by a receptor-like kinase (RLK) complex that includes
EMS1. Mutations in members of this EMS1 signalling complex and its putative ligand
result in male-sterile plants in which tapetal initials fail to proliferate. Surprisingly,
these cells continue to develop, isolated at the locular periphery. Mutant and
wild-type microsporangia expand at similar rates and the ‘tapetal’ space at the
periphery of mutant locules becomes occupied by microsporocytes. However, induction
of late expression of EMS1 in the few tapetal initials in ems1 plants results
in their proliferation to generate a functional tapetum, and this proliferation
suppresses microsporocyte number. Our experiments also show that integrity of
the tapetal monolayer is crucial for the maintenance of the polarity of divisions
within it. This unexpected autonomy of the tapetal ‘lineage’ is discussed in the
context of tissue development in complex plant organs, where constancy in size,
shape and cell number is crucial.

text: Key steps in the evolution of the angiosperm anther include the patterning
of the concentrically organized microsporangium and the incorporation of four
such microsporangia into a leaf-like structure. Mutant studies in the model plant
Arabidopsis thaliana are leading to an increasingly accurate picture of (i) the
cell lineages culminating in the different cell types present in the microsporangium
(the microsporocytes, the tapetum, and the middle and endothecial layers), and
(ii) some of the genes responsible for specifying their fates. However, the processes
that confer polarity on the developing anther and position the microsporangia
within it remain unclear. Certainly, data from a range of experimental strategies
suggest that hormones play a central role in establishing polarity and the patterning
of the anther initial, and may be responsible for locating the microsporangia.
But the fact that microsporangia were originally positioned externally suggests
that their development is likely to be autonomous, perhaps with the reproductive
cells generating signals controlling the growth and division of the investing
anther epidermis. These possibilities are discussed in the context of the expression
of genes which initiate and maintain male and female reproductive development,
and in the perspective of our current views of anther evolution.

text: 'Daily streamflow from stations close to five Swiss glaciers is analyzed for
trends with the Mann-Kendall test. We consider a common period of record (1974–2004)
and longer periods based on data availability. The trend statistical significance
is tested on annual and seasonal bases. We also examine changes in precipitation,
temperature, and snow cover characteristics. Highly glacierized basins show statistically
significant positive trends in annual streamflow caused by increasing streamflow
in spring and summer. Trends are more numerous and stronger at lower and mid than
at the upper quantiles. The basin characterized by lower glacier coverage, conversely,
does not exhibit consistently statistically significant trends. Changes in precipitation
are not sufficient to explain the observed streamflow trends. Air temperature
sees an increase in mean, minimum, and maximum values at all sites. Variations
in the seasonal snow accumulation and ablation process are evident. Solid precipitation
is decreasing at all sites and trends may be due to a shift from snowfall into
rainfall. Mean snow depth is also decreasing, and its duration is getting shorter
because of a decrease in solid precipitation and enhanced melting. Trend magnitude
attenuates with longer time series. Contrasting trends are detected for different
subperiods in the last 70 years: statistically significant negative trends are
observed in the periods 1944–1974 and 1954–1984 for Aletschgletscher, in contrast
with the results for the common period. These trends are explained by different
rates of ice volume changes, and the sign of trends is clearly related to phases
of positive or negative glacier mass balance.'

text: 'Motion vision is a major function of all visual systems, yet the underlying
neural mechanisms and circuits are still elusive. In the lamina, the first optic
neuropile of Drosophila melanogaster, photoreceptor signals split into five parallel
pathways, L1-L5. Here we examine how these pathways contribute to visual motion
detection by combining genetic block and reconstitution of neural activity in
different lamina cell types with whole-cell recordings from downstream motion-sensitive
neurons. We find reduced responses to moving gratings if L1 or L2 is blocked;
however, reconstitution of photoreceptor input to only L1 or L2 results in wild-type
responses. Thus, the first experiment indicates the necessity of both pathways,
whereas the second indicates sufficiency of each single pathway. This contradiction
can be explained by electrical coupling between L1 and L2, allowing for activation
of both pathways even when only one of them receives photoreceptor input. A fundamental
difference between the L1 pathway and the L2 pathway is uncovered when blocking
L1 or L2 output while presenting moving edges of positive (ON) or negative (OFF)
contrast polarity: blocking L1 eliminates the response to moving ON edges, whereas
blocking L2 eliminates the response to moving OFF edges. Thus, similar to the
segregation of photoreceptor signals in ON and OFF bipolar cell pathways in the
vertebrate retina, photoreceptor signals segregate into ON-L1 and OFF-L2 channels
in the lamina of Drosophila.'

text: Motion vision is essential for navigating through the environment. Due to
its genetic amenability, the fruit fly Drosophila has been serving for a lengthy
period as a model organism for studying optomotor behavior as elicited by large-field
horizontal motion. However, the neurons underlying the control of this behavior
have not been studied in Drosophila so far. Here we report the first whole cell
recordings from three cells of the horizontal system (HSN, HSE, and HSS) in the
lobula plate of Drosophila. All three HS cells are tuned to large-field horizontal
motion in a direction-selective way; they become excited by front-to-back motion
and inhibited by back-to-front motion in the ipsilateral field of view. The response
properties of HS cells such as contrast and velocity dependence are in accordance
with the correlation-type model of motion detection. Neurobiotin injection suggests
extensive coupling among ipsilateral HS cells and additional coupling to tangential
cells that have their dendrites in the contralateral hemisphere of the brain.
This connectivity scheme accounts for the complex layout of their receptive fields
and explains their sensitivity both to ipsilateral and to contralateral motion.
Thus the main response properties of Drosophila HS cells are strikingly similar
to the responses of their counterparts in the blowfly Calliphora, although we
found substantial differences with respect to their dendritic structure and connectivity.
This long-awaited functional characterization of HS cells in Drosophila provides
the basis for the future dissection of optomotor behavior and the underlying neural
circuitry by combining genetics, physiology, and behavior.

text: This paper describes a passive stereo system for capturing the 3D geometry
of a face in a single-shot under standard light sources. The system is low-cost
and easy to deploy. Results are submillimeter accurate and commensurate with those
from state-ofthe-art systems based on active lighting, and the models meet the
quality requirements of a demanding domain like the movie industry. Recovered
models are shown for captures from both high-end cameras in a studio setting and
from a consumer binocular-stereo camera, demonstrating scalability across a spectrum
of camera deployments, and showing the potential for 3D face modeling to move
beyond the professional arena and into the emerging consumer market in stereoscopic
photography. Our primary technical contribution is a modification of standard
stereo refinement methods to capture pore-scale geometry, using a qualitative
approach that produces visually realistic results. The second technical contribution
is a calibration method suited to face capture systems. The systemic contribution
includes multiple demonstrations of system robustness and quality. These include
capture in a studio setup, capture off a consumer binocular-stereo camera, scanning
of faces of varying gender and ethnicity and age, capture of highly-transient
facial expression, and scanning a physical mask to provide ground-truth validation.

text: Point-based graphics has gained much attention as an alternative to polygon-based
approaches because of its simplicity and flexibility. However, current point-based
techniques do not provide a sufficient rendering quality for translucent materials
such as human skin. In this paper, we propose a point-based framework with subsurface
scattering of light, which is important to create the soft and semi-translucent
appearance of human skin. To accurately simulate subsurface scattering in multilayered
materials, we present splat-based diffusion to apply a linear combination of several
Gaussian basis functions to each splat in object space. Compared to existing point-based
approaches, our method offers a significantly improved visual quality in rendering
human faces and provides a similar visual quality to polygon-based rendering using
the texture space diffusion technique. We demonstrate the effectiveness of our
approach in rendering scanned faces realistically.

text: This paper introduces a data-driven process for designing and fabricating
materials with desired deformation behavior. Our process starts with measuring
deformation properties of base materials. For each base material we acquire a
set of example deformations, and we represent the material as a non-linear stress-strain
relationship in a finite-element model. We have validated our material measurement
process by comparing simulations of arbitrary stacks of base materials with measured
deformations of fabricated material stacks. After material measurement, our process
continues with designing stacked layers of base materials. We introduce an optimization
process that finds the best combination of stacked layers that meets a user's
criteria specified by example deformations. Our algorithm employs a number of
strategies to prune poor solutions from the combinatorial search space. We demonstrate
the complete process by designing and fabricating objects with complex heterogeneous
materials using modern multi-material 3D printers.

text: We develop a theory of Malliavin calculus for Banach space-valued random variables.
Using radonifying operators instead of symmetric tensor products we extend the
Wiener-Itô isometry to Banach spaces. In the white noise case we obtain two sided
Lp-estimates for multiple stochastic integrals in arbitrary Banach spaces. It
is shown that the Malliavin derivative is bounded on vector-valued Wiener-Itô
chaoses. Our main tools are decoupling inequalities for vector-valued random variables.
In the opposite direction we use Meyer's inequalities to give a new proof of a
decoupling result for Gaussian chaoses in UMD Banach spaces.

text: We develop an analytic model of vector correlations in rotationally inelastic
atom-diatom collisions and test it against the much examined Ar-NO (X2Π) system.
Based on the Fraunhofer scattering of matter waves, the model furnishes complex
scattering amplitudes needed to evaluate the polarization moments characterizing
the quantum stereodynamics. The analytic polarization moments are found to be
in an excellent agreement with experimental results and with close-coupling calculations
available at thermal energies. The model reveals that the stereodynamics is governed
by diffraction from the repulsive core of the Ar-NO potential, which can be characterized
by a single Legendre moment.

text: 'Following upon our recent work on vector correlations in the Ar-NO collisions
[Lemeshko and Friedrich, Phys. Chem. Chem. Phys. 12, 1038 (2010)], we compare
model results with close-coupling calculations for a range of channels and collision
energies for the He-NO system. The striking agreement between the model and exact
polarization moments indicates that the stereodynamics of rotationally inelastic
atom-molecule collisions at thermal energies is governed by diffraction of matter
waves from a two-dimensional repulsive core of the atom-molecule potential. Furthermore,
the model polarization moments characterizing the He-NO, He- O2, He-OH, and He-CaH
stereodynamics are found to coalesce into a single, distinctive pattern, which
can serve as a "fingerprint" to identify diffraction-driven stereodynamics
in future work. '

text: We evaluate the shifts imparted to vibrational and rotational levels of a
linear molecule by a nonresonant laser field at intensities of up to 10 12 W/cm2.
Both types of shift are found to be either positive or negative, depending on
the initial rotational state acted upon by the field. An adiabatic field-molecule
interaction imparts a rotational energy shift which is negative and exceeds the
concomitant positive vibrational shift by a few orders of magnitude. The rovibrational
states are thus pushed downward in such a field. A nonresonant pulsed laser field
that interacts nonadiabatically with the molecule is found to impart rotational
and vibrational shifts of the same order of magnitude. The nonadiabatic energy
transfer occurs most readily at a pulse duration which amounts to about a tenth
of the molecule's rotational period and vanishes when the sudden regime is attained
for shorter pulses. We applied our treatment to the much-studied 87Rb2 molecule
in the last bound vibrational levels of its lowest singlet and triplet electronic
states. Our calculations indicate that 15 and 1.5 ns laser pulses of an intensity
in excess of 5 × 109 W/cm2 are capable of dissociating the molecule due to the
vibrational shift. Lesser shifts can be used to fine-tune the rovibrational levels
and thereby affect collisional resonances by the nonresonant light. The energy
shifts due to laser intensities of 109 W/cm2 may be discernible spectroscopically,
with a 10 MHz resolution.

text: We present an analytic model of the refractive index for matter waves propagating
through atomic or molecular gases. The model, which combines the Wentzel-Kramers-Brillouin
(WKB) treatment of the long-range attraction with the Fraunhofer model treatment
of the short-range repulsion, furnishes a refractive index in compelling agreement
with recent experiments of Jacquey [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.98.240405
98, 240405 (2007)] on Li atom matter waves passing through dilute noble gases.
We show that the diffractive contribution, which arises from scattering by a two-dimensional
"hard core" of the potential, is essential for obtaining a correct imaginary
part of the refractive index.

text: The immobilization of molecular switches onto inorganic supports has recently
become a hot topic as it can give rise to novel hybrid materials in which the
properties of the two components are mutually enhanced. Even more attractive is
the concept of “transferring” the switchable characteristics of single layers
of organic molecules onto the underlying inorganic components, rendering them
responsive to external stimuli as well. Of the various molecular switches studied,
azobenzene (AB) has arguably attracted most attention due to its simple molecular
structure, and because its “trigger” (light) is a noninvasive one, it can be delivered
instantaneously, and into a precise location. In order to fully realize its potential,
however, it is necessary to immobilize AB onto solid supports. It is the goal
of this manuscript to comprehensively yet concisely review such hybrid systems
which comprise AB forming well-defined self-assembled monolayers (SAMs) on planar
and curved (colloidal and nanoporous) inorganic surfaces. I discuss methods to
immobilize AB derivatives onto surfaces, strategies to ensure efficient AB isomerization,
ways to monitor the switching process, properties of these switchable hybrid materials,
and, last but not least, their emerging applications.
