text: We use scanning tunneling microscope break-junction (STM-BJ) measurements
to study the low-bias conductance and high-bias current–voltage (IV) characteristics
of a series of asymmetric para–meta connected diphenyl-oligoenes. From tight-binding
calculations, we determine that the quantum interference features inherent in
our molecular design result in a ‘through-bond’ coupling on the para-side, and
through-space coupling on the meta-side. We show that these molecular junctions
form single molecule diodes, and show that the rectification results from a difference
in the voltage dependence of the coupling strength on the through-bond and the
through-space side. The interplay between the applied voltage and the molecule–metal
coupling results from the asymmetric polarizability of the conducting orbital
under an external field.

text: 'We have measured the single-molecule conductance of a family of oligothiophenes
comprising 1–6 thiophene moieties terminated with methyl-sulfide linkers using
the scanning tunneling microscope-based break-junction technique. We find an anomalous
behavior: the peak of the conductance histogram distribution does not follow a
clear exponential decay with increasing number of thiophene units in the chain.
The electronic properties of the materials were characterized by optical spectroscopy
and electrochemistry to gain an understanding of the factors affecting the conductance
of these molecules. We postulate that different conformers in the junction are
a contributing factor to the anomalous trend in the observed conductance as a
function of molecule length.'

text: A direct measurement of the potential energy surface that characterizes individual
chemical bonds in complex materials has fundamental significance for many disciplines.
Here, we demonstrate that the energy profile for metallic single-atom contacts
and single-molecule junctions can be mapped by fitting ambient atomic force microscope
measurements carried out in the near-equilibrium regime to a physical, but simple,
functional form. We extract bond energies for junctions formed through metallic
bonds as well as metal–molecule link bonds from atomic force microscope data and
find that our results are in excellent quantitative agreement with density functional
theory based calculations for exemplary junction structures. Furthermore, measurements
from a large number of junctions can be collapsed to a single, universal force–extension
curve, thus revealing a surprising degree of similarity in the overall shape of
the potential surface that governs these chemical bonds. Compared to previous
studies under ambient conditions where analysis was confined to trends in rupture
force, our approach significantly expands the quantitative information extracted
from these measurements, particularly allowing analysis of the trends in bond
energy directly.

text: We have designed and synthesized five azulene derivatives containing gold-binding
groups at different points of connectivity within the azulene core to probe the
effects of quantum interference through single-molecule conductance measurements.
We compare conducting paths through the 5-membered ring, 7-membered ring, and
across the long axis of azulene. We find that changing the points of connectivity
in the azulene impacts the optical properties (as determined from UV–vis absorption
spectra) and the conductivity. Importantly, we show here that simple models cannot
be used to predict quantum interference characteristics of nonalternant hydrocarbons.
As an exemplary case, we show that azulene derivatives that are predicted to exhibit
destructive interference based on widely accepted atom-counting models show a
significant conductance at low biases. Although simple models to predict the low-bias
conductance do not hold with all azulene derivatives, we demonstrate that the
measured conductance trend for all molecules studied actually agrees with predictions
based on the more complete GW calculations for model systems.

text: Molecular electronics demands complex functional molecules with multiple pathways
connecting electrode leads. We report the synthesis and study of a set of molecules
based on a fluorene-like design in which atomic connectors are used to introduce
two pathways for conductance. This manuscript details the structural demands and
underlying rationale for developing high conductance in these complex molecular

text: We modulate the conductance of electrochemically inactive molecules in single-molecule
junctions using an electrolytic gate to controllably tune the energy level alignment
of the system. Molecular junctions that conduct through their highest occupied
molecular orbital show a decrease in conductance when applying a positive electrochemical
potential, and those that conduct though their lowest unoccupied molecular orbital
show the opposite trend. We fit the experimentally measured conductance data as
a function of gate voltage with a Lorentzian function and find the fitting parameters
to be in quantitative agreement with self-energy corrected density functional
theory calculations of transmission probability across single-molecule junctions.
This work shows that electrochemical gating can directly modulate the alignment
of the conducting orbital relative to the metal Fermi energy, thereby changing
the junction transport properties.

text: We measure conductance and thermopower of single Au–4,4′-bipyridine–Au junctions
in distinct low and high conductance binding geometries accessed by modulating
the electrode separation. We use these data to determine the electronic energy
level alignment and coupling strength for these junctions, which are known to
conduct through the lowest unoccupied molecular orbital (LUMO). Contrary to intuition,
we find that, in the high-conductance junction, the LUMO resonance energy is further
away from the Au Fermi energy than in the low-conductance junction. However, the
LUMO of the high-conducting junction is better coupled to the electrode. These
results are in good quantitative agreement with self-energy corrected zero-bias
density functional theory calculations. Our calculations show further that measurements
of conductance and thermopower in amine-terminated oligophenyl–Au junctions, where
conduction occurs through the highest occupied molecular orbitals, cannot be used
to extract electronic parameters as their transmission functions do not follow
a simple Lorentzian form.

text: 'We have measured the conductance of single-molecule junctions created with
three different molecular wires using the scanning tunneling microscope-based
break-junction technique. Each wire contains one of three different cyclic five-membered
rings: cyclopentadiene, furan, or thiophene. We find that the single-molecule
conductance of these three wires correlates negatively with the resonance energy
of the five-membered ring; the nonaromatic cyclopentadiene derivative has the
highest conductance, while the most aromatic of this series, thiophene, has the
lowest. Furthermore, we show for another wire structure that the conductance of
furan-based wires is consistently higher than for analogous thiophene systems,
indicating that the negative correlation between conductance and aromaticity is
robust. The best conductance would be for a quinoid structure that diminishes
aromaticity. The energy penalty for partly adopting the quinoid structure is less
with compounds having lower initial aromatic stabilization. An additional effect
may reflect the lower HOMOs of aromatic compounds.'

text: Molecular junctions formed using the scanning-tunneling-microscope–based break-junction
technique (STM-BJ) have provided unique insight into charge transport at the nanoscale.
In most prior work, the same metal, typically Au, Pt, or Ag, is used for both
tip and substrate. For such noble metal electrodes, the density of electronic
states is approximately constant within a narrow energy window relevant to charge
transport. Here, we form molecular junctions using the STM-BJ technique, with
an Au metal tip and a microfabricated graphite substrate, and measure the conductance
of a series of graphite/amine-terminated oligophenyl/Au molecular junctions. The
remarkable mechanical strength of graphite and the single-crystal properties of
our substrates allow measurements over few thousand junctions without any change
in the surface properties. We show that conductance decays exponentially with
molecular backbone length with a decay constant that is essentially the same as
that for measurements with two Au electrodes. More importantly, despite the inherent
symmetry of the oligophenylamines, we observe rectification in these junctions.
State-of-art ab initio conductance calculations are in good agreement with experiment,
and explain the rectification. We show that the highly energy-dependent graphite
density of states contributes variations in transmission that, when coupled with
an asymmetric voltage drop across the junction, leads to the observed rectification.
Together, our measurements and calculations show how functionality may emerge
from hybrid molecular-scale devices purposefully designed with different electrodes
beyond the so-called “wide band limit,” opening up the possibility of assembling
molecular junctions with dissimilar electrodes using layered 2D materials.

text: The generation of asymmetry, at both cellular and tissue level, is one of
the most essential capabilities of all eukaryotic organisms. It mediates basically
all multicellular development ranging from embryogenesis and de novo organ formation
till responses to various environmental stimuli. In plants, the awe-inspiring
number of such processes is regulated by phytohormone auxin and its directional,
cell-to-cell transport. The mediators of this transport, PIN auxin transporters,
are asymmetrically localized at the plasma membrane, and this polar localization
determines the directionality of intercellular auxin flow. Thus, auxin transport
contributes crucially to the generation of local auxin gradients or maxima, which
instruct given cell to change its developmental program. Here, we introduce and
discuss the molecular components and cellular mechanisms regulating the generation
and maintenance of cellular PIN polarity, as the general hallmarks of cell polarity
in plants.

text: Watermarking techniques for vector graphics dislocate vertices in order to
embed imperceptible, yet detectable, statistical features into the input data.
The embedding process may result in a change of the topology of the input data,
e.g., by introducing self-intersections, which is undesirable or even disastrous
for many applications. In this paper we present a watermarking framework for two-dimensional
vector graphics that employs conventional watermarking techniques but still provides
the guarantee that the topology of the input data is preserved. The geometric
part of this framework computes so-called maximum perturbation regions (MPR) of
vertices. We propose two efficient algorithms to compute MPRs based on Voronoi
diagrams and constrained triangulations. Furthermore, we present two algorithms
to conditionally correct the watermarked data in order to increase the watermark
embedding capacity and still guarantee topological correctness. While we focus
on the watermarking of input formed by straight-line segments, one of our approaches
can also be extended to circular arcs. We conclude the paper by demonstrating
and analyzing the applicability of our framework in conjunction with two well-known
watermarking techniques.

text: "We present an optical setup with focus-tunable lenses to dynamically control
the waist and focus position of a laser beam, in which we transport a trapped
ultracold cloud of 87Rb over a distance of \r\n. The scheme allows us to shift
the focus position at constant waist, providing uniform trapping conditions over
the full transport length. The fraction of atoms that are transported over the
entire distance comes near to unity, while the heating of the cloud is in the
range of a few microkelvin. We characterize the position stability of the focus
and show that residual drift rates in focus position can be compensated for by
counteracting with the tunable lenses. Beyond being a compact and robust scheme
to transport ultracold atoms, the reported control of laser beams makes dynamic
tailoring of trapping potentials possible. As an example, we steer the size of
the atomic cloud by changing the waist size of the dipole beam."

text: Hitting and batting tasks, such as tennis forehands, ping-pong strokes, or
baseball batting, depend on predictions where the ball can be intercepted and
how it can properly be returned to the opponent. These predictions get more accurate
over time, hence the behaviors need to be continuously modified. As a result,
movement templates with a learned global shape need to be adapted during the execution
so that the racket reaches a target position and velocity that will return the
ball over to the other side of the net or court. It requires altering learned
movements to hit a varying target with the necessary velocity at a specific instant
in time. Such a task cannot be incorporated straightforwardly in most movement
representations suitable for learning. For example, the standard formulation of
the dynamical system based motor primitives (introduced by Ijspeert et al (2002b))
does not satisfy this property despite their flexibility which has allowed learning
tasks ranging from locomotion to kendama. In order to fulfill this requirement,
we reformulate the Ijspeert framework to incorporate the possibility of specifying
a desired hitting point and a desired hitting velocity while maintaining all advantages
of the original formulation.We show that the proposed movement template formulation
works well in two scenarios, i.e., for hitting a ball on a string with a table
tennis racket at a specified velocity and for returning balls launched by a ball
gun successfully over the net using forehand movements.

text: Traditional models of bendable surfaces are based on the exact or approximate
invariance to deformations that do not tear or stretch the shape, leaving intact
an intrinsic geometry associated with it. These geometries are typically defined
using either the shortest path length (geodesic distance), or properties of heat
diffusion (diffusion distance) on the surface. Both measures are implicitly derived
from the metric induced by the ambient Euclidean space. In this paper, we depart
from this restrictive assumption by observing that a different choice of the metric
results in a richer set of geometric invariants. We apply equi-affine geometry
for analyzing arbitrary shapes with positive Gaussian curvature. The potential
of the proposed framework is explored in a range of applications such as shape
matching and retrieval, symmetry detection, and computation of Voroni tessellation.
We show that in some shape analysis tasks, equi-affine-invariant intrinsic geometries
often outperform their Euclidean-based counterparts. We further explore the potential
of this metric in facial anthropometry of newborns. We show that intrinsic properties
of this homogeneous group are better captured using the equi-affine metric.

text: 'Traditionally, NMF algorithms consist of two separate stages: a training
stage, in which a generative model is learned; and a testing stage in which the
pre-learned model is used in a high level task such as enhancement, separation,
or classification. As an alternative, we propose a task-supervised NMF method
for the adaptation of the basis spectra learned in the first stage to enhance
the performance on the specific task used in the second stage. We cast this problem
as a bilevel optimization program that can be efficiently solved via stochastic
gradient descent. The proposed approach is general enough to handle sparsity priors
of the activations, and allow non-Euclidean data terms such as β-divergences.
The framework is evaluated on single-channel speech enhancement tasks.'

text: Informative and discriminative feature descriptors play a fundamental role
in deformable shape analysis. For example, they have been successfully employed
in correspondence, registration, and retrieval tasks. In recent years, significant
attention has been devoted to descriptors obtained from the spectral decomposition
of the Laplace-Beltrami operator associated with the shape. Notable examples in
this family are the heat kernel signature (HKS) and the recently introduced wave
kernel signature (WKS). The Laplacian-based descriptors achieve state-of-the-art
performance in numerous shape analysis tasks; they are computationally efficient,
isometry-invariant by construction, and can gracefully cope with a variety of
transformations. In this paper, we formulate a generic family of parametric spectral
descriptors. We argue that to be optimized for a specific task, the descriptor
should take into account the statistics of the corpus of shapes to which it is
applied (the "signal") and those of the class of transformations to which it is
made insensitive (the "noise"). While such statistics are hard to model axiomatically,
they can be learned from examples. Following the spirit of the Wiener filter in
signal processing, we show a learning scheme for the construction of optimized
spectral descriptors and relate it to Mahalanobis metric learning. The superiority
of the proposed approach in generating correspondences is demonstrated on synthetic
and scanned human figures. We also show that the learned descriptors are robust
enough to be learned on synthetic data and transferred successfully to scanned
shapes.

text: We introduce an efficient computational framework for hashing data belonging
to multiple modalities into a single representation space where they become mutually
comparable. The proposed approach is based on a novel coupled siamese neural network
architecture and allows unified treatment of intra- and inter-modality similarity
learning. Unlike existing cross-modality similarity learning approaches, our hashing
functions are not limited to binarized linear projections and can assume arbitrarily
complex forms. We show experimentally that our method significantly outperforms
state-of-the-art hashing approaches on multimedia retrieval tasks.
