Let K be an irreducible and reversible Markov kernel on a finite set X. We construct a metric W on the set of probability measures on X and show that with respect to this metric, the law of the continuous time Markov chain evolves as the gradient flow of the entropy. This result is a discrete counterpart of the Wasserstein gradient flow interpretation of the heat flow in Rn by Jordan, Kinderlehrer and Otto (1998). The metric W is similar to, but different from, the L2-Wasserstein metric, and is defined via a discrete variant of the Benamou–Brenier formula.

text: A (diatomic) shape resonance is a metastable state of a pair of colliding
atoms quasi-bound by the centrifugal barrier imposed by the angular momentum involved
in the collision. The temporary trapping of the atoms' scattering wavefunction
corresponds to an enhanced atom pair density at low interatomic separations. This
leads to larger overlap of the wavefunctions involved in a molecule formation
process such as photoassociation, rendering the process more efficient. However,
for an ensemble of atoms, the atom pair density will only be enhanced if the energy
of the resonance comes close to the temperature of the atomic ensemble. Herein
we explore the possibility of controlling the energy of a shape resonance by shifting
it toward the temperature of atoms confined in a trap. The shifts are imparted
by the interaction of non-resonant light with the anisotropic polarizability of
the atom pair, which affects both the centrifugal barrier and the pair's rotational
and vibrational levels. We find that at laser intensities of up to 5×109 W/cm2
the pair density is increased by one order of magnitude for 87Rb atoms at 100μK
and by two orders of magnitude for 88Sr atoms at 20μK.

text: We show that dressing polar molecules with a far-off-resonant optical field
leads to new types of intermolecular potentials, which undergo a crossover from
the inverse power to oscillating behavior depending on the intermolecular distance,
and whose parameters can be tuned by varying the laser intensity and wavelength.
We present analytic expressions for the potential energy surfaces, thereby providing
direct access to the parameters of an optical field required to design intermolecular
interactions experimentally.

text: By invoking supersymmetry, we found a condition under which the Stark-effect
problem for a polar and polarizable molecule subject to nonresonant electric fields
becomes exactly solvable for the family of stretched states. The analytic expressions
for the wave function and eigenenergy and other expectation values allow one to
readily reverse-engineer the problem of finding the values of the interaction
parameters required for creating quantum states with preordained characteristics.
The method also allows the construction of families of isospectral potentials,
realizable with combined fields.

text: We made use of supersymmetric (SUSY) quantum mechanics to find the condition
under which the Stark effect problem for a polar and polarizable closed-shell
diatomic molecule subjected to collinear electrostatic and nonresonant radiative
fields becomes exactly solvable. The condition Δω = ω2/4(m+1)2 connects values
of the dimensionless parameters ω and Δω that characterize the strengths of the
permanent and induced dipole interactions of the molecule with the respective
fields. The exact solutions are obtained for the \J̃ = m, m; ω, Δω) family of
'stretched' states. The field-free and strong-field limits of the combined-fields
problem were found to exhibit supersymmetry and shape invariance, which is indeed
the reason why they are analytically solvable. By making use of the analytic form
of the \J̃ = m,m; ω, Δω) wavefunctions, we obtained simple formulae for the expectation
values of the space-fixed electric dipole moment, the alignment cosine and the
angular momentum squared, and derived a 'sum rule' that combines the above expectation
values into a formula for the eigenenergy. The analytic expressions for the characteristics
of the strongly oriented and aligned states provide direct access to the values
of the interaction parameters required for creating such states in the laboratory.

text: The binding of polarons, or its absence, is an old and subtle topic. After
defining the model we state some recent theorems of ours. First, the transition
from many-body collapse to the existence of a thermodynamic limit for N polarons
occurs precisely at U = 2α, where U is the electronic Coulomb repulsion and α
is the polaron coupling constant. Second, if U is large enough, there is no multi-polaron
binding of any kind. We also discuss the Pekar-Tomasevich approximation to the
ground state energy, which is valid for large α. Finally, we derive exact results,
not reported before, about the one-dimensional toy model introduced by E. P. Gross.

text: 'We resolve several longstanding problems concerning the stability and the
absence of multi-particle binding for N≥2 polarons. Fröhlich''s 1937 polaron model
describes non-relativistic particles interacting with a scalar quantized field
with coupling √α, and with each other by Coulomb repulsion of strength U. We prove
the following: (i) While there is a known thermodynamic instability for U<2α,
stability of matter does hold for U>2α, that is, the ground state energy per
particle has a finite limit as N→∞. (ii) There is no binding of any kind if U
exceeds a critical value that depends on α but not on N. The same results are
shown to hold for the Pekar-Tomasevich model.'

text: The change in energy of an ideal Fermi gas when a local one-body potential
is inserted into the system, or when the density is changed locally, are important
quantities in condensed matter physics. We show that they can be rigorously bounded
from below by a universal constant times the value given by the semiclassical
approximation.

text: Within a multicellular tissue cells may coordinately form a singular or multiple
polar axes, but it is unclear whether a common mechanism governs different types
of polar axis formation. The phosphorylation status of PIN proteins, which is
directly affected by the PINOID (PID) protein kinase and the PP2A protein phosphatase,
is known to regulate the apical-basal polarity of PIN localization in bipolar
cells of roots and shoot apices. Here, we provide evidence that the phosphorylation
status-mediated PIN polarity switch is widely used to modulate cellular processes
in Arabidopsis including multipolar pavement cells (PC) with interdigitated lobes
and indentations. The degree of PC interdigitation was greatly reduced either
when the FYPP1 gene, which encodes a PP2A called phytochrome-associated serine/threonine
protein phosphatase, was knocked out or when the PID gene was overexpressed (35S:PID).
These genetic modifications caused PIN1 localization to switch from lobe to indentation
regions. The PP2A and PID mediated switching of PIN1 localization is strikingly
similar to their regulation of the apical-basal polarity switch of PIN proteins
in other cells. Our findings suggest a common mechanism for the regulation of
PIN1 polarity formation, a fundamental cellular process that is crucial for pattern
formation both at the tissue/organ and cellular levels.

Rapid research progress in genotyping techniques have allowed large genome-wide association studies. Existing methods often focus on determining associations between single loci and a specic phenotype. However, a particular phenotype is usually the result of complex relationships between multiple loci and the environment. In this paper, we describe a two-stage method for detecting epistasis by combining the traditionally used single-locus search with a search for multiway interactions. Our method is based on an extended version of Fisher's exact test. To
perform this test, a Markov chain is constructed on the space of multidimensional contingency tables using the elements of a Markov basis as moves. We test our method on simulated data and compare it to a two-stage logistic regression method and to a fully Bayesian method, showing that we are able to detect the interacting loci when other methods fail to do so. Finally, we apply our method to a genome-wide data set consisting of 685 dogs and identify epistasis associated with canine hair length for four pairs of single nucleotide polymorphisms (SNPs).

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.

text: In multicellular organisms, morphogenesis relies on a strict coordination
in time and space of cell proliferation and differentiation. In contrast to animals,
plant development displays continuous organ formation and adaptive growth responses
during their lifespan relying on a tight coordination of cell proliferation. How
developmental signals interact with the plant cell-cycle machinery is largely
unknown. Here, we characterize plant A2-type cyclins, a small gene family of mitotic
cyclins, and show how they contribute to the fine-tuning of local proliferation
during plant development. Moreover, the timely repression of CYCA2;3 expression
in newly formed guard cells is shown to require the stomatal transcription factors
FOUR LIPS/MYB124 and MYB88, providing a direct link between developmental programming
and cell-cycle exit in plants. Thus, transcriptional downregulation of CYCA2s
represents a critical mechanism to coordinate proliferation during plant development.

text: Subcellular trafficking is required for a multitude of functions in eukaryotic
cells. It involves regulation of cargo sorting, vesicle formation, trafficking
and fusion processes at multiple levels. Adaptor protein (AP) complexes are key
regulators of cargo sorting into vesicles in yeast and mammals but their existence
and function in plants have not been demonstrated. Here we report the identification
of the protein-affected trafficking 4 (pat4) mutant defective in the putative
δ subunit of the AP-3 complex. pat4 and pat2, a mutant isolated from the same
GFP imaging-based forward genetic screen that lacks a functional putative AP-3
β, as well as dominant negative AP-3 μ transgenic lines display undistinguishable
phenotypes characterized by largely normal morphology and development, but strong
intracellular accumulation of membrane proteins in aberrant vacuolar structures.
All mutants are defective in morphology and function of lytic and protein storage
vacuoles (PSVs) but show normal sorting of reserve proteins to PSVs. Immunoprecipitation
experiments and genetic studies revealed tight functional and physical associations
of putative AP-3 β and AP-3 δ subunits. Furthermore, both proteins are closely
linked with putative AP-3 μ and σ subunits and several components of the clathrin
and dynamin machineries. Taken together, these results demonstrate that AP complexes,
similar to those in other eukaryotes, exist in plants, and that AP-3 plays a specific
role in the regulation of biogenesis and function of vacuoles in plant cells.

text: The unintentional scattering of light between neighboring surfaces in complex
projection environments increases the brightness and decreases the contrast, disrupting
the appearance of the desired imagery. To achieve satisfactory projection results,
the inverse problem of global illumination must be solved to cancel this secondary
scattering. In this paper, we propose a global illumination cancellation method
that minimizes the perceptual difference between the desired imagery and the actual
total illumination in the resulting physical environment. Using Gauss-Newton and
active set methods, we design a fast solver for the bound constrained nonlinear
least squares problem raised by the perceptual error metrics. Our solver is further
accelerated with a CUDA implementation and multi-resolution method to achieve
1–2 fps for problems with approximately 3000 variables. We demonstrate the global
illumination cancellation algorithm with our multi-projector system. Results show
that our method preserves the color fidelity of the desired imagery significantly
better than previous methods.

text: 'Chemokines organize immune cell trafficking by inducing either directed (tactic)
or random (kinetic) migration and by activating integrins in order to support
surface adhesion (haptic). Beyond that the same chemokines can establish clearly
defined functional areas in secondary lymphoid organs. Until now it is unclear
how chemokines can fulfill such diverse functions. One decisive prerequisite to
explain these capacities is to know how chemokines are presented in tissue. In
theory chemokines could occur either soluble or immobilized, and could be distributed
either homogenously or as a concentration gradient. To dissect if and how the
presenting mode of chemokines influences immune cells, I tested the response of
dendritic cells (DCs) to differentially displayed chemokines. DCs are antigen
presenting cells that reside in the periphery and migrate into draining lymph
nodes (LNs) once exposed to inflammatory stimuli to activate naïve T cells. DCs
are guided to and within the LN by the chemokine receptor CCR7, which has two
ligands, the chemokines CCL19 and CCL21. Both CCR7 ligands are expressed by fibroblastic
reticular cells in the LN, but differ in their ability to bind to heparan sulfate
residues. CCL21 has a highly charged C-terminal extension, which mediates binding
to anionic surfaces, whereas CCL19 is lacking such residues and likely distributes
as a soluble molecule. This study shows that surface-bound CCL21 causes random,
haptokinetic DC motility, which is confined to the chemokine coated area by insideout
activation of β2 integrins that mediate cell binding to the surface. CCL19 on
the other hand forms concentration gradients which trigger directional, chemotactic
movement, but no surface adhesion. In addition DCs can actively manipulate this
system by recruiting and activating serine proteases on their surfaces, which
create - by proteolytically removing the adhesive C-terminus - a solubilized variant
of CCL21 that functionally resembles CCL19. By generating a CCL21 concentration
gradient DCs establish a positive feedback loop to recruit further DCs from the
periphery to the CCL21 coated region. In addition DCs can sense chemotactic gradients
as well as immobilized haptokinetic fields at the same time and integrate these
signals. The result is chemotactically biased haptokinesis - directional migration
confined to a chemokine coated track or area - which could explain the dynamic
but spatially tightly controlled swarming leukocyte locomotion patterns that have
been observed in lymphatic organs by intravital microscopists. The finding that
DCs can approach soluble cues in a non-adhesive manner while they attach to surfaces
coated with immobilized cues raises the question how these cells transmit intracellular
forces to the environment, especially in the non-adherent migration mode. In order
to migrate, cells have to generate and transmit force to the extracellular substrate.
Force transmission is the prerequisite to procure an expansion of the leading
edge and a forward motion of the whole cell body. In the current conceptions actin
polymerization at the leading edge is coupled to extracellular ligands via the
integrin family of transmembrane receptors, which allows the transmission of intracellular
force. Against the paradigm of force transmission during migration, leukocytes,
like DCs, are able to migrate in threedimensional environments without using integrin
transmembrane receptors (Lämmermann et al., 2008). This reflects the biological
function of leukocytes, as they can invade almost all tissues, whereby their migration
has to be independent from the extracellular environment. How the cells can achieve
this is unclear. For this study I examined DC migration in a defined threedimensional
environment and highlighted actin-dynamics with the probe Lifeact-GFP. The result
was that chemotactic DCs can switch between integrin-dependent and integrin- independent
locomotion and can thereby adapt to the adhesive properties of their environment.
If the cells are able to couple their actin cytoskeleton to the substrate, actin
polymerization is entirely converted into protrusion. Without coupling the actin
cortex undergoes slippage and retrograde actin flow can be observed. But retrograde
actin flow can be completely compensated by higher actin polymerization rate keeping
the migration velocity and the shape of the cells unaltered. Mesenchymal cells
like fibroblast cannot balance the loss of adhesive interaction, cannot protrude
into open space and, therefore, strictly depend on integrinmediated force coupling.
This leukocyte specific phenomenon of “adaptive force transmission” endows these
cells with the unique ability to transit and invade almost every type of tissue. '

text: 'We present an algorithm to identify individual neural spikes observed on
high-density multi-electrode arrays (MEAs). Our method can distinguish large numbers
of distinct neural units, even when spikes overlap, and accounts for intrinsic
variability of spikes from each unit. As MEAs grow larger, it is important to
find spike-identification methods that are scalable, that is, the computational
cost of spike fitting should scale well with the number of units observed. Our
algorithm accomplishes this goal, and is fast, because it exploits the spatial
locality of each unit and the basic biophysics of extracellular signal propagation.
Human interaction plays a key role in our method; but effort is minimized and
streamlined via a graphical interface. We illustrate our method on data from guinea
pig retinal ganglion cells and document its performance on simulated data consisting
of spikes added to experimentally measured background noise. We present several
tests demonstrating that the algorithm is highly accurate: it exhibits low error
rates on fits to synthetic data, low refractory violation rates, good receptive
field coverage, and consistency across users.'

abstract:
- lang: eng
text: 'The zonula adherens (ZA) of epithelial cells is a site of cell-cell adhesion
where cellular forces are exerted and resisted. Increasing evidence indicates
that E-cadherin adhesion molecules at the ZA serve to sense force applied on the
junctions and coordinate cytoskeletal responses to those forces. Efforts to understand
the role that cadherins play in mechanotransduction have been limited by the lack
of assays to measure the impact of forces on the ZA. In this study we used 4D
imaging of GFP-tagged E-cadherin to analyse the movement of the ZA. Junctions
in confluent epithelial monolayers displayed prominent movements oriented orthogonal
(perpendicular) to the ZA itself. Two components were identified in these movements:
a relatively slow unidirectional (translational) component that could be readily
fitted by least-squares regression analysis, upon which were superimposed more
rapid oscillatory movements. Myosin IIB was a dominant factor responsible for
driving the unilateral translational movements. In contrast, frequency spectrum
analysis revealed that depletion of Myosin IIA increased the power of the oscillatory
movements. This implies that Myosin IIA may serve to dampen oscillatory movements
of the ZA. This extends our recent analysis of Myosin II at the ZA to demonstrate
that Myosin IIA and Myosin IIB make distinct contributions to junctional movement
at the ZA.'
