text: Electrical and thermal transport properties of C60 molecules are investigated
with density-functional-theory based calculations. These calculations suggest
that the optimum contact geometry for an electrode terminated with a single-Au
atom is through binding to one or two C-atoms of C60 with a tendency to promote
the sp2-hybridization into an sp3-type one. Transport in these junctions is
primarily through an unoccupied molecular orbital that is partly hybridized with
the Au, which results in splitting the degeneracy of the lowest unoccupied molecular
orbital triplet. The transmission through these junctions, however, cannot be
modeled by a single Lorentzian resonance, as our results show evidence of quantum
interference between an occupied and an unoccupied orbital. The interference results
in a suppression of conductance around the Fermi energy. Our numerical findings
are readily analyzed analytically within a simple two-level model.

text: Here we demonstrate for the first time that strained silanes couple directly
to gold electrodes in break-junction conductance measurements. We find that strained
silicon molecular wires terminated by alkyl sulfide aurophiles behave effectively
as single-molecule parallel circuits with competing sulfur-to-sulfur (low G) and
sulfur-to-silacycle (high G) pathways. We can switch off the high conducting sulfur-to-silacycle
pathway by altering the environment of the electrode surface to disable the Au–silacycle
coupling. Additionally, we can switch between conductive pathways in a single
molecular junction by modulating the tip–substrate electrode distance. This study
provides a new molecular design to control electronics in silicon-based single
molecule wires.

text: We demonstrate a new method of achieving rectification in single molecule
devices using the high-bias properties of gold–carbon bonds. Our design for molecular
rectifiers uses a symmetric, conjugated molecular backbone with a single methylsulfide
group linking one end to a gold electrode and a covalent gold–carbon bond at the
other end. The gold–carbon bond results in a hybrid gold-molecule “gateway” state
pinned close to the Fermi level of one electrode. Through nonequilibrium transport
calculations, we show that the energy of this state shifts drastically with applied
bias, resulting in rectification at surprisingly low voltages. We use this concept
to design and synthesize a family of diodes and demonstrate through single-molecule
current–voltage measurements that the rectification ratio can be predictably and
efficiently tuned. This result constitutes the first experimental demonstration
of a rationally tunable system of single-molecule rectifiers. More generally,
the results demonstrate that the high-bias properties of “gateway” states can
be used to provide additional functionality to molecular electronic systems.

text: Charge transfer through noncovalent interactions is crucial to a variety of
chemical phenomena. These interactions are often weak and nonspecific and can
coexist, making it difficult to isolate the transfer efficiency of one type of
bond versus another. Here, we show how core-hole clock spectroscopy can be used
to measure charge transfer through noncovalent interactions. We study the model
system 1,4-benzenediamine molecules bound on an Au surface through an Au–N donor–acceptor
bond as these are known to provide a pathway for electronic conduction in molecular
devices. We study different phases of the molecule/Au system and map charge delocalization
times from carbon and nitrogen sites on the molecule. We show that charge delocalization
across Au–N donor–acceptor bond occurs in less than 500 as. Furthermore, the Au–N
bond also enhances delocalization times from neighboring carbon sites, demonstrating
that fast charge transfer across a metal–organic interface does not require a
covalently bonded system.

text: We have measured the single-molecule conductance of a family of bithiophene
derivatives terminated with methyl sulfide gold-binding linkers using a scanning
tunneling microscope based break-junction technique. We find a broad distribution
in the single-molecule conductance of bithiophene compared with that of a methyl
sulfide terminated biphenyl. Using a combination of experiments and calculations,
we show that this increased breadth in the conductance distribution is explained
by the difference in 5-fold symmetry of thiophene rings as compared to the 6-fold
symmetry of benzene rings. The reduced symmetry of thiophene rings results in
a restriction on the torsion angle space available to these molecules when bound
between two metal electrodes in a junction, causing each molecular junction to
sample a different set of conformers in the conductance measurements. In contrast,
the rotations of biphenyl are essentially unimpeded by junction binding, allowing
each molecular junction to sample similar conformers. This work demonstrates that
the conductance of bithiophene displays a strong dependence on the conformational
fluctuations accessible within a given junction configuration, and that the symmetry
of such small molecules can significantly influence their conductance behaviors.

text: We compare the conductance of a series of amine-terminated oligophenyl and
alkane molecular junctions formed with Ag and Au electrodes using the scanning
tunneling microscope based break-junction technique. For these molecules that
conduct through the highest occupied molecular orbital, junctions formed with
Au electrodes are more conductive than those formed with Ag electrodes, consistent
with the lower work function for Ag. The measured conductance decays exponentially
with molecular backbone length with a decay constant that is essentially the same
for Ag and Au electrodes. However, the formation and evolution of molecular junctions
upon elongation are very different for these two metals. Specifically, junctions
formed with Ag electrodes sustain significantly longer elongation when compared
with Au due to a difference in the initial gap opened up when the metal point-contact
is broken. Using this observation and density functional theory calculations of
junction structure and conductance we explain the trends observed in the single
molecule junction conductance. Our work thus opens a new path to the conductance
measurements of a single molecule junction in Ag electrodes.

text: We report the simultaneous measurement of conductance and thermopower of highly
conducting single-molecule junctions using a scanning tunneling microscope-based
break-junction setup. We start with molecular backbones (alkanes and oligophenyls)
terminated with trimethyltin end groups that cleave off in situ to create junctions
where terminal carbons are covalently bonded to the Au electrodes. We apply a
thermal gradient across these junctions and measure their conductance and thermopower.
Because of the electronic properties of the highly conducting Au–C links, the
thermoelectric properties and power factor are very high. Our results show that
the molecular thermopower increases nonlinearly with the molecular length while
conductance decreases exponentially with increasing molecular length. Density
functional theory calculations show that a gateway state representing the Au–C
covalent bond plays a key role in the conductance. With this as input, we analyze
a series of simplified models and show that a tight-binding model that explicitly
includes the gateway states and the molecular backbone states accurately captures
the experimentally measured conductance and thermopower trends.

text: We measure simultaneously force and conductance of Ag metal point-contacts
under ambient conditions at room temperature. We observe the formation of contacts
with a conductance close to 1 G0, the quantum of conductance, which can be attributed
to a single-atom contact, similar to those formed by Au. We also find two additional
conductance features at ∼0.4 G0 and ∼1.3 G0, which have been previously ascribed
to contacts with oxygen contaminations. Here, using a conductance cross-correlation
technique, we distinguish three different atomic-scale structural motifs and analyze
their rupture forces and stiffness. Our results allow us to assign the ∼0.4 G0
conductance feature to an Ag–O–Ag contact and the ∼1.3 G0 feature to an Ag–Ag
single-atom contact with an oxygen atom in parallel. Utilizing complementary information
from force and conductance, we thus demonstrate the correlation of conductance
with the structural evolution at the atomic scale.

text: The idea of using individual molecules as active electronic components provided
the impetus to develop a variety of experimental platforms to probe their electronic
transport properties. Among these, single-molecule junctions in a metal–molecule–metal
motif have contributed significantly to our fundamental understanding of the principles
required to realize molecular-scale electronic components from resistive wires
to reversible switches. The success of these techniques and the growing interest
of other disciplines in single-molecule-level characterization are prompting new
approaches to investigate metal–molecule–metal junctions with multiple probes.
Going beyond electronic transport characterization, these new studies are highlighting
both the fundamental and applied aspects of mechanical, optical and thermoelectric
properties at the atomic and molecular scales. Furthermore, experimental demonstrations
of quantum interference and manipulation of electronic and nuclear spins in single-molecule
circuits are heralding new device concepts with no classical analogues. In this
Review, we present the emerging methods being used to interrogate multiple properties
in single molecule-based devices, detail how these measurements have advanced
our understanding of the structure–function relationships in molecular junctions,
and discuss the potential for future research and applications.

text: Motion-based segmentation is an important tool for the analysis of articulated
shapes. As such, it plays an important role in mechanical engineering, computer
graphics, and computer vision. In this chapter, we study motion-based segmentation
of 3D articulated shapes. We formulate motion-based surface segmentation as a
piecewise-smooth regularization problem for the transformations between several
poses. Using Lie-group representation for the transformation at each surface point,
we obtain a simple regularized fitting problem. An Ambrosio-Tortorelli scheme
of a generalized Mumford-Shah model gives us the segmentation functional without
assuming prior knowledge on the number of parts or even the articulated nature
of the object. Experiments on several standard datasets compare the results of
the proposed method to state-of-the-art algorithms.

text: Feature-based analysis is becoming a very popular approach for geometric shape
analysis. Following the success of this approach in image analysis, there is a
growing interest in finding analogous methods in the 3D world. Maximally stable
component detection is a low computation cost and high repeatability method for
feature detection in images.In this study, a diffusion-geometry based framework
for stable component detection is presented, which can be used for geometric feature
detection in deformable shapes.The vast majority of studies of deformable 3D shapes
models them as the two-dimensional boundary of the volume of the shape. Recent
works have shown that a volumetric shape model is advantageous in numerous ways
as it better captures the natural behavior of non-rigid deformations. We show
that our framework easily adapts to this volumetric approach, and even demonstrates
superior performance.A quantitative evaluation of our methods on the SHREC’10
and SHREC’11 feature detection benchmarks as well as qualitative tests on the
SCAPE dataset show its potential as a source of high-quality features. Examples
demonstrating the drawbacks of surface stable components and the advantage of
their volumetric counterparts are also presented.

text: In this paper we present a framework for real time enhancement of speech signals.
Our method leverages a new process-centric approach for sparse and parsimonious
models, where the representation pursuit is obtained applying a deterministic
function or process rather than solving an optimization problem. We first propose
a rank-regularized robust version of non-negative matrix factorization (NMF) for
modeling time-frequency representations of speech signals in which the spectral
frames are decomposed as sparse linear combinations of atoms of a low-rank dictionary.
Then, a parametric family of pursuit processes is derived from the iteration of
the proximal descent method for solving this model. We present several experiments
showing successful results and the potential of the proposed framework. Incorporating
discriminative learning makes the proposed method significantly outperform exact
NMF algorithms, with fixed latency and at a fraction of it's computational complexity.

text: A method for removing impulse noise from audio signals by fusing multiple
copies of the same recording is introduced in this paper. The proposed algorithm
exploits the fact that while in general multiple copies of a given recording are
available, all sharing the same master, most degradations in audio signals are
record-dependent. Our method first seeks for the optimal non-rigid alignment of
the signals that is robust to the presence of sparse outliers with arbitrary magnitude.
Unlike previous approaches, we simultaneously find the optimal alignment of the
signals and impulsive degradation. This is obtained via continuous dynamic time
warping computed solving an Eikonal equation. We propose to use our approach in
the derivative domain, reconstructing the signal by solving an inverse problem
that resembles the Poisson image editing technique. The proposed framework is
here illustrated and tested in the restoration of old gramophone recordings showing
promising results; however, it can be used in other applications where different
copies of the signal of interest are available and the degradations are copy-dependent.

text: Dynamic Time Warping (DTW), is a simple but efficient technique for matching
sequences with rigid deformation. Therefore, it is frequently used for matching
shapes in general, and shapes of handwritten words in Document Image Analysis
tasks. As DTW is computationally expensive, efficient algorithms for fast computation
are crucial. Retrieving images from large scale datasets using DTW, suffers from
the constraint of linear searching of all sample in the datasets. Fast approximation
algorithms for image retrieval are mostly based on normed spaces where the triangle
inequality holds, which is unfortunately not the case with the DTW metric. In
this paper we present a novel approach for fast search of handwritten words within
large datasets of shapes. The presented approach is based on the Boost-Map [1]
algorithm, for embedding the feature space with the DTW measurement to an euclidean
space and use the Local Sensitivity Hashing algorithm (LSH) to rank the k-nearest
neighbors of a query image. The algorithm, first, processes and embeds objects
of the large data sets to a normed space. Fast approximation of k-nearest neighbors
using LSH on the embedding space, generates the top kranked samples which are
examined using the real DTW distance to give final accurate results. We demonstrate
our method on a database of 45; 800 images of word-parts extracted from the IFN/ENIT
database [11] and images collected from 51 different writers. Our method achieves
a speedup of 4 orders of magnitude over the exact method, at the cost of only
a 2:2% reduction in accuracy.

text: The use of Laplacian eigenbases has been shown to be fruitful in many computer
graphics applications. Today, state-of-the-art approaches to shape analysis, synthesis,
and correspondence rely on these natural harmonic bases that allow using classical
tools from harmonic analysis on manifolds. However, many applications involving
multiple shapes are obstacled by the fact that Laplacian eigenbases computed independently
on different shapes are often incompatible with each other. In this paper, we
propose the construction of common approximate eigenbases for multiple shapes
using approximate joint diagonalization algorithms, taking as input a set of corresponding
functions (e.g. indicator functions of stable regions) on the two shapes. We illustrate
the benefits of the proposed approach on tasks from shape editing, pose transfer,
correspondence, and similarity.

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 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: "\r\n\r\nElg1 and Srs2 are two proteins involved in maintaining genome stability
in yeast. After DNA damage, the homotrimeric clamp PCNA, which provides stability
and processivity to DNA polymerases and serves as a docking platform for DNA repair
enzymes, undergoes modification by the ubiquitin-like molecule SUMO. PCNA SUMOylation
helps recruit Srs2 and Elg1 to the replication fork. In the absence of Elg1, both
SUMOylated PCNA and Srs2 accumulate at the chromatin fraction, indicating that
Elg1 is required for removing SUMOylated PCNA and Srs2 from DNA. Despite this
interaction, which suggests that the two proteins work together, double mutants
elg1Δ srs2Δ have severely impaired growth as haploids and exhibit synergistic
sensitivity to DNA damage and a synergistic increase in gene conversion. In addition,
diploid elg1Δ srs2Δ double mutants are dead, which implies that an essential function
in the cell requires at least one of the two gene products for survival. To gain
information about this essential function, we have carried out a high copy number
suppressor screen to search for genes that, when overexpressed, suppress the synthetic
lethality between elg1Δ and srs2Δ. We report the identification of 36 such genes,
which are enriched for functions related to DNA- and chromatin-binding, chromatin
packaging and modification, and mRNA export from the nucleus."

text: In this paper, we explore the use of the diffusion geometry framework for
the fusion of geometric and photometric information in local and global shape
descriptors. Our construction is based on the definition of a diffusion process
on the shape manifold embedded into a high-dimensional space where the embedding
coordinates represent the photometric information. Experimental results show that
such data fusion is useful in coping with different challenges of shape analysis
where pure geometric and pure photometric methods fail.

text: Partial similarity of shapes is a challenging problem arising in many important
applications in computer vision, shape analysis, and graphics, e.g. when one has
to deal with partial information and acquisition artifacts. The problem is especially
hard when the underlying shapes are non-rigid and are given up to a deformation.
Partial matching is usually approached by computing local descriptors on a pair
of shapes and then establishing a point-wise non-bijective correspondence between
the two, taking into account possibly different parts. In this paper, we introduce
an alternative correspondence-less approach to matching fragments to an entire
shape undergoing a non-rigid deformation. We use region-wise local descriptors
and optimize over the integration domains on which the integral descriptors of
the two parts match. The problem is regularized using the Mumford-Shah functional.
We show an efficient discretization based on the Ambrosio-Tortorelli approximation
generalized to triangular point clouds and meshes, and present experiments demonstrating
the success of the proposed method.

text: We consider the Gross–Pitaevskii equation on R^4 and the cubic-quintic nonlinear
Schrödinger equation (NLS) on R^3 with non-vanishing boundary conditions at spatial
infinity. By viewing these equations as perturbations to the energy-critical NLS,
we prove that they are globally well-posed in their energy spaces. In particular,
we prove unconditional uniqueness in the energy spaces for these equations.
