text: Guidelines to predict trends in the electrical conductance of molecules have
been developed for the π-system of conjugated systems. Little is known, however,
about the conductance of the underlying σ-systems because the π-system usually
dominates the transport. Here we study a family of bipyridine-based molecules
using STM-break junction experiments and density functional theory transport calculations.
We use different lengths and substitution patterns to probe the role of both the
σ-system and the π-system in controlling conductance. By exploiting the destructive
interference feature found in the π-system of the meta-coupled six-membered aromatic
rings, we show that the conductance of the σ-system of a meta-coupled molecule
can be probed directly and can even exceed that of its para-coupled analog. These
results add to the understanding of the conductance through the chemically hidden
σ-electrons.

text: The development of molecular components functioning as switches, rectifiers
or amplifiers is a great challenge in molecular electronics. A desirable property
of such components is functional robustness, meaning that the intrinsic functionality
of components must be preserved regardless of the strategy used to integrate them
into the final assemblies. Here, this issue is investigated for molecular diodes
based on N-phenylbenzamide (NPBA) backbones. The transport properties of molecular
junctions derived from NPBA are characterized while varying the nature of the
functional groups interfacing the backbone and the gold electrodes required for
break-junction measurements. Combining experimental and theoretical methods, it
is shown that at low bias (<0.85 V) transport is determined by the same frontier
molecular orbital originating from the NPBA core, regardless of the anchoring
group employed. The magnitude of rectification, however, is strongly dependent
on the strength of the electronic coupling at the gold–NPBA interface and on the
spatial distribution of the local density of states of the dominant transport
channel of the molecular junction.

text: A highly conducting electronic contact between a strained disilane and Au
is demonstrated through scanning tunneling microscope-based single-molecule measurements.
Conformationally locked cis diastereomers of bis(sulfide)-anchor-equipped 1,2-disilaacenaphthenes
readily form high-conducting junctions in which the two sulfide anchors bind in
a bipodal fashion to one gold electrode, providing enough stability for a stable
electrical contact between the Si–Si σ bond and the other electrode.

text: 'While the single-molecule conductance properties of π-conjugated and σ-conjugated
systems have been well-studied, little is known regarding the conductance properties
of mixed σ–π backbone wires and the factors that control their transport properties.
Here we utilize a scanning tunneling microscope-based break-junction technique
to study a series of molecular wires with π–σ–π backbone structures, where the
π-moiety is an electrode-binding thioanisole ring and the σ-moiety is a triatomic
α–β–α chain composed of C, Si, or Ge atoms. We find that the sequence and composition
of group 14 atoms in the α–β–α chain dictates whether electronic communication
between the aryl rings is enhanced or suppressed. Placing heavy atoms at the α-position
decreases conductance, whereas placing them at the β-position increases conductance:
for example, the C–Ge–C sequence is over 20 times more conductive than the Ge–C–Ge
sequence. Density functional theory calculations reveal that these conductance
trends arise from periodic trends (i.e., atomic size, polarizability, and electronegativity)
that differ from C to Si to Ge. The periodic trends that control molecular conductance
here are the same ones that give rise to the α and β silicon effects from physical
organic chemistry. These findings outline a new molecular design concept for tuning
conductance in single-molecule electrical devices.'

text: 'Charge transport phenomena in single-molecule junctions are often dominated
by tunneling, with a transmission function dictating the probability that electrons
or holes tunnel through the junction. Here, we present a new and simple technique
for measuring the transmission functions of molecular junctions in the coherent
tunneling limit, over an energy range of 1.5 eV around the Fermi energy. We create
molecular junctions in an ionic environment with electrodes having different exposed
areas, which results in the formation of electric double layers of dissimilar
density on the two electrodes. This allows us to electrostatically shift the molecular
resonance relative to the junction Fermi levels in a manner that depends on the
sign of the applied bias, enabling us to map out the junction’s transmission function
and determine the dominant orbital for charge transport in the molecular junction.
We demonstrate this technique using two groups of molecules: one group having
molecular resonance energies relatively far from EF and one group having molecular
resonance energies within the accessible bias window. Our results compare well
with previous electrochemical gating data and with transmission functions computed
from first principles. Furthermore, with the second group of molecules, we are
able to examine the behavior of a molecular junction as a resonance shifts into
the bias window. This work provides a new, experimentally simple route for exploring
the fundamentals of charge transport at the nanoscale.'

text: Single-molecule conductance measurements have focused primarily on organic
molecular systems. Here, we carry out scanning tunneling microscope-based break-junction
measurements on a series of metal chalcogenide Co6Se8 clusters capped with conducting
ligands of varying lengths. We compare these measurements with those of individual
free ligands and find that the conductance of these clusters and the free ligands
have different decay constants with increasing ligand length. We also show, through
measurements in two different solvents, 1-bromonaphthalene and 1,2,4-trichlorobenzene,
that the conductance decay of the clusters depends on the solvent environment.
We discuss several mechanisms to explain our observations.

text: "Over the past 10 years, there has been tremendous progress in the measurement,
modeling and understanding of structure–function relationships in single molecule
junctions. Numerous research groups have addressed significant scientific questions,
directed both to conductance phenomena at the single molecule level and to the
fundamental chemistry that controls junction functionality. Many different functionalities
have been demonstrated, including single-molecule diodes, optically and mechanically
activated switches, and, significantly, physical phenomena with no classical analogues,
such as those based on quantum interference effects. Experimental techniques for
reliable and reproducible single molecule junction formation and characterization
have led to this progress. In particular, the scanning tunneling microscope based
break-junction (STM-BJ) technique has enabled rapid, sequential measurement of
large numbers of nanoscale junctions allowing a statistical analysis to readily
distinguish reproducible characteristics. Harnessing fundamental link chemistry
has provided the necessary chemical control over junction formation, enabling
measurements that revealed clear relationships between molecular structure and
conductance characteristics. Such link groups (amines, methylsuflides, pyridines,
etc.) maintain a stable lone pair configuration that selectively bonds to specific,
undercoordinated transition metal atoms available following rupture of a metal
point contact in the STM-BJ experiments. This basic chemical principle rationalizes
the observation of highly reproducible conductance signatures. Subsequently, the
method has been extended to probe a variety of physical phenomena ranging from
basic I–V characteristics to more complex properties such as thermopower and electrochemical
response. By adapting the technique to a conducting cantilever atomic force microscope
(AFM-BJ), simultaneous measurement of the mechanical characteristics of nanoscale
junctions as they are pulled apart has given complementary information such as
the stiffness and rupture force of the molecule-metal link bond. Overall, while
the BJ technique does not produce a single molecule circuit for practical applications,
it has proved remarkably versatile for fundamental studies. Measured data and
analysis have been combined with atomic-scale theory and calculations, typically
performed for representative junction structures, to provide fundamental physical
understanding of structure–function relationships.\r\n\r\nThis Account integrates
across an extensive series of our specific nanoscale junction studies which were
carried out with the STM- and AFM-BJ techniques and supported by theoretical analysis
and density functional theory based calculations, with emphasis on the physical
characteristics of the measurement process and the rich data sets that emerge.
Several examples illustrate the impact of measured trends based on the most probable
values for key characteristics (obtained from ensembles of order 1000–10 000 individual
junctions) to build a solid picture of conductance phenomena as well as attributes
of the link bond chemistry. The key forward-looking question posed here is the
extent to which the full data sets represented by the individual trajectories
can be analyzed to address structure–function questions at the level of individual
junctions. Initial progress toward physical modeling of conductance of individual
junctions indicates trends consistent with physical junction structures. Analysis
of junction mechanics reveals a scaling procedure that collapses existing data
onto a universal force–extension curve. This research directed to understanding
the distribution of structures and physical characteristics addresses fundamental
questions concerning the interplay between chemical control and stochastically
driven diversity."

text: 'The field of single-molecule electronics harnesses expertise from engineering,
physics and chemistry to realize circuit elements at the limit of miniaturization;
it is a subfield of nanoelectronics in which the electronic components are single
molecules. In this Review, we survey the field from a chemical perspective and
discuss the structure–property relationships of the three components that form
a single-molecule junction: the anchor, the electrode and the molecular bridge.
The spatial orientation and electronic coupling between each component profoundly
affect the conductance properties and functions of the single-molecule device.
We describe the design principles of the anchor group, the influence of the electronic
configuration of the electrode and the effect of manipulating the structure of
the molecular backbone and of its substituent groups. We discuss single-molecule
conductance switches as well as the phenomenon of quantum interference and then
trace their fundamental roots back to chemical principles.'

text: We examine structure–function relationships in a series of N-phenylbenzamide
(NPBA) derivatives by using computational modeling to identify molecular structures
that exhibit both rectification and good conductance together with experimental
studies of bias-dependent single molecule conductance and rectification behavior
using the scanning tunneling microscopy break-junction technique. From a large
number of computationally screened molecular diode structures, we have identified
NPBA as a promising candidate, relative to the other structures that were screened.
We demonstrate experimentally that conductance and rectification are both enhanced
by functionalization of the NPBA 4-carboxamido-aniline moiety with electron donating
methoxy groups, and are strongly correlated with the energy of the conducting
frontier orbital relative to the Fermi level of the gold leads used in break-junction
experiments.

text: Here we examine the impact of ring conformation on the charge transport characteristics
of cyclic pentasilane structures bound to gold electrodes in single molecule junctions.
We investigate the conductance properties of alkylated cyclopentasilane cis and
trans stereoisomers substituted in the 1,3-position with methylthiomethyl electrode
binding groups using both the scanning tunneling microscope-based break junction
technique and density functional theory based ab initio calculations. In contrast
with the linear ones, these cyclic silanes yield lower conductance values; calculations
reveal that the constrained dihedral geometries occurring within the ring are
suboptimal for σ-orbital delocalization, and therefore, conductance. Theoretical
calculations reproduce the measured conductance trends for both cis and trans
isomers and find several distinct conformations that are likely to form stable
molecular junctions at room temperature. Due to the weakened σ-conjugation in
the molecule, through-space interactions are found to contribute significantly
to the conductance. This manuscript details the vast conformational flexibility
in cyclopentasilanes and the tremendous impact it has on controlling conductance.

text: Charge transfer rates at metal/organic interfaces affect the efficiencies
of devices for organic based electronics and photovoltaics. A quantitative study
of electron transfer rates, which take place on the femtosecond timescale, is
often difficult, especially since in most systems the molecular adsorption geometry
is unknown. Here, we use X-ray resonant photoemission spectroscopy to measure
ultrafast charge transfer rates across pyridine/Au(111) interfaces while also
controlling the molecular orientation on the metal. We demonstrate that a bi-directional
charge transfer across the molecule/metal interface is enabled upon creation of
a core-exciton on the molecule with a rate that has a strong dependence on the
molecular adsorption angle. Through density functional theory calculations, we
show that the alignment of molecular levels relative to the metal Fermi level
is dramatically altered when a core-hole is created on the molecule, allowing
the lowest unoccupied molecular orbital to fall partially below the metal Fermi
level. We also calculate charge transfer rates as a function of molecular adsorption
geometry and find a trend that agrees with the experiment. These findings thus
give insight into the charge transfer dynamics of a photo-excited molecule on
a metal surface.

text: We present a novel sparse modeling approach to non-rigid shape matching using
only the ability to detect repeatable regions. As the input to our algorithm,
we are given only two sets of regions in two shapes; no descriptors are provided
so the correspondence between the regions is not know, nor do we know how many
regions correspond in the two shapes. We show that even with such scarce information,
it is possible to establish very accurate correspondence between the shapes by
using methods from the field of sparse modeling, being this, the first non-trivial
use of sparse models in shape correspondence. We formulate the problem of permuted
sparse coding, in which we solve simultaneously for an unknown permutation ordering
the regions on two shapes and for an unknown correspondence in functional representation.
We also propose a robust variant capable of handling incomplete matches. Numerically,
the problem is solved efficiently by alternating the solution of a linear assignment
and a sparse coding problem. The proposed methods are evaluated qualitatively
and quantitatively on standard benchmarks containing both synthetic and scanned
objects.

text: 'Relational models for contingency tables are generalizations of log-linear
models, allowing effects associated with arbitrary subsets of cells in the table,
and not necessarily containing the overall effect, that is, a common parameter
in every cell. Similarly to log-linear models, relational models can be extended
to non-negative distributions, but the extension requires more complex methods.
An extended relational model is defined as an algebraic variety, and it turns
out to be the closure of the original model with respect to the Bregman divergence.
In the extended relational model, the MLE of the cell parameters always exists
and is unique, but some of its properties may be different from those of the MLE
under log-linear models. The MLE can be computed using a generalized iterative
scaling procedure based on Bregman projections. '

text: 3D models of humans are commonly used within computer graphics and vision,
and so the ability to distinguish between body shapes is an important shape retrieval
problem. We extend our recent paper which provided a benchmark for testing non-rigid
3D shape retrieval algorithms on 3D human models. This benchmark provided a far
stricter challenge than previous shape benchmarks. We have added 145 new models
for use as a separate training set, in order to standardise the training data
used and provide a fairer comparison. We have also included experiments with the
FAUST dataset of human scans. All participants of the previous benchmark study
have taken part in the new tests reported here, many providing updated results
using the new data. In addition, further participants have also taken part, and
we provide extra analysis of the retrieval results. A total of 25 different shape
retrieval methods are compared.

text: The L 1 norm has been tremendously popular in signal and image processing
in the past two decades due to its sparsity-promoting properties. More recently,
its generalization to non-Euclidean domains has been found useful in shape analysis
applications. For example, in conjunction with the minimization of the Dirichlet
energy, it was shown to produce a compactly supported quasi-harmonic orthonormal
basis, dubbed as compressed manifold modes [14]. The continuous L 1 norm on the
manifold is often replaced by the vector ℓ 1 norm applied to sampled functions.
We show that such an approach is incorrect in the sense that it does not consistently
discretize the continuous norm and warn against its sensitivity to the specific
sampling. We propose two alternative discretizations resulting in an iteratively-reweighed
ℓ 2 norm. We demonstrate the proposed strategy on the compressed modes problem,
which reduces to a sequence of simple eigendecomposition problems not requiring
non-convex optimization on Stiefel manifolds and producing more stable and accurate
results.

text: We present a method to approximate pairwise distance on a graph, having an
amortized sub-linear complexity in its size. The proposed method follows the so
called heat method due to Crane et al. The only additional input are the values
of the eigenfunctions of the graph Laplacian at a subset of the vertices. Using
these values we estimate a random walk from the source points, and normalize the
result into a unit gradient function. The eigenfunctions are then used to synthesize
distance values abiding by these constraints at desired locations. We show that
this method works in practice on different types of inputs ranging from triangular
meshes to general graphs. We also demonstrate that the resulting approximate distance
is accurate enough to be used as the input to a recent method for intrinsic shape
correspondence computation.

text: The pursuit of smaller pixel sizes at ever increasing resolution in digital
image sensors is mainly driven by the stringent price and form-factor requirements
of sensors and optics in the cellular phone market. Recently, Eric Fossum proposed
a novel concept of an image sensor with dense sub-diffraction limit one-bit pixels
(jots), which can be considered a digital emulation of silver halide photographic
film. This idea has been recently embodied as the EPFL Gigavision camera. A major
bottleneck in the design of such sensors is the image reconstruction process,
producing a continuous high dynamic range image from oversampled binary measurements.
The extreme quantization of the Poisson statistics is incompatible with the assumptions
of most standard image processing and enhancement frameworks. The recently proposed
maximum-likelihood (ML) approach addresses this difficulty, but suffers from image
artefacts and has impractically high computational complexity. In this work, we
study a variant of a sensor with binary threshold pixels and propose a reconstruction
algorithm combining an ML data fitting term with a sparse synthesis prior. We
also show an efficient hardware-friendly real-time approximation of this inverse
operator. Promising results are shown on synthetic data as well as on HDR data
emulated using multiple exposures of a regular CMOS sensor.

text: Three important properties of a classification machinery are i) the system
preserves the core information of the input data; ii) the training examples convey
information about unseen data; and iii) the system is able to treat differently
points from different classes. In this paper, we show that these fundamental properties
are satisfied by the architecture of deep neural networks. We formally prove that
these networks with random Gaussian weights perform a distance-preserving embedding
of the data, with a special treatment for in-class and out-of-class data. Similar
points at the input of the network are likely to have a similar output. The theoretical
analysis of deep networks here presented exploits tools used in the compressed
sensing and dictionary learning literature, thereby making a formal connection
between these important topics. The derived results allow drawing conclusions
on the metric learning properties of the network and their relation to its structure,
as well as providing bounds on the required size of the training set such that
the training examples would represent faithfully the unseen data. The results
are validated with state-of-the-art trained networks.

text: Shape correspondence is a fundamental problem in computer graphics and vision,
with applications in various problems including animation, texture mapping, robotic
vision, medical imaging, archaeology and many more. In settings where the shapes
are allowed to undergo non-rigid deformations and only partial views are available,
the problem becomes very challenging. To this end, we present a non-rigid multi-part
shape matching algorithm. We assume to be given a reference shape and its multiple
parts undergoing a non-rigid deformation. Each of these query parts can be additionally
contaminated by clutter, may overlap with other parts, and there might be missing
parts or redundant ones. Our method simultaneously solves for the segmentation
of the reference model, and for a dense correspondence to (subsets of) the parts.
Experimental results on synthetic as well as real scans demonstrate the effectiveness
of our method in dealing with this challenging matching scenario.

text: Sparse models in dictionary learning have been successfully applied in a wide
variety of machine learning and computer vision problems, and as a result have
recently attracted increased research interest. Another interesting related problem
based on linear equality constraints, namely the sparse null space (SNS) problem,
first appeared in 1986 and has since inspired results on sparse basis pursuit.
In this paper, we investigate the relation between the SNS problem and the analysis
dictionary learning (ADL) problem, and show that the SNS problem plays a central
role, and may be utilized to solve dictionary learning problems. Moreover, we
propose an efficient algorithm of sparse null space basis pursuit (SNS-BP) and
extend it to a solution of ADL. Experimental results on numerical synthetic data
and real-world data are further presented to validate the performance of our method.
