text: Electronic factors in molecules such as quantum interference and cross-conjugation
can lead to dramatic modulation and suppression of conductance in single-molecule
junctions. Probing such effects at the single-molecule level requires simultaneous
measurements of independent junction properties, as conductance alone cannot provide
conclusive evidence of junction formation for molecules with low conductivity.
Here, we compare the mechanics of the conducting para-terminated 4,4′-di(methylthio)stilbene
and moderately conducting 1,2-bis(4-(methylthio)phenyl)ethane to that of insulating
meta-terminated 3,3′-di(methylthio)stilbene single-molecule junctions. We simultaneously
measure force and conductance across single-molecule junctions and use force signatures
to obtain independent evidence of junction formation and rupture in the meta-linked
cross-conjugated molecule even when no clear low-bias conductance is measured.
By separately quantifying conductance and mechanics, we identify the formation
of atypical 3,3′-di(methylthio)stilbene molecular junctions that are mechanically
stable but electronically decoupled. While theoretical studies have envisaged
many plausible systems where quantum interference might be observed, our experiments
provide the first direct quantitative study of the interplay between contact mechanics
and the distinctively quantum mechanical nature of electronic transport in single-molecule
junctions.

text: We use a modified conducting atomic force microscope to simultaneously probe
the conductance of a single-molecule junction and the force required to rupture
the junction formed by alkanes terminated with four different chemical link groups
which vary in binding strength and mechanism to the gold electrodes. Molecular
junctions with amine, methylsulfide, and diphenylphosphine terminated molecules
show clear conductance signatures and rupture at a force that is significantly
smaller than the measured 1.4 nN force required to rupture the single-atomic gold
contact. In contrast, measurements with a thiol terminated alkane which can bind
covalently to the gold electrode show conductance and force features unlike those
of the other molecules studied. Specifically, the strong Au–S bond can cause structural
rearrangements in the electrodes, which are accompanied by substantial conductance
changes. Despite the strong Au–S bond and the evidence for disruption of the Au
structure, the experiments show that on average these junctions also rupture at
a smaller force than that measured for pristine single-atom gold contacts.

text: Van der Waals (vdW) interaction, and its subtle interplay with chemically
specific interactions and surface roughness at metal/organic interfaces, is critical
to the understanding of structure–function relations in diverse areas, including
catalysis, molecular electronics and self-assembly1,2,3. However, vdW interactions
remain challenging to characterize directly at the fundamental, single-molecule
level both in experiments and in first principles calculations with accurate treatment
of the non-local, London dispersion interactions. In particular, for metal/organic
interfaces, efforts so far have largely focused on model systems consisting of
adsorbed molecules on flat metallic surfaces with minimal specific chemical interaction4,5,6,7,8,9.
Here we show, through measurements of single-molecule mechanics, that pyridine
derivatives10,11 can bind to nanostructured Au electrodes through an additional
binding mechanism beyond the chemically specific N–Au donor–acceptor bond. Using
density functional theory simulations we show that vdW interactions between the
pyridine ring and Au electrodes can play a key role in the junction mechanics.
These measurements thus provide a quantitative characterization of vdW interactions
at metal/organic interfaces at the single-molecule level.

text: Owing to thermal fluctuations, two-dimensional (2D) systems cannot undergo
a conventional phase transition associated with the breaking of a continuous symmetry1.
Nevertheless they may exhibit a phase transition to a state with quasi-long-range
order via the Berezinskii–Kosterlitz–Thouless (BKT) mechanism2. A paradigm example
is the 2D Bose fluid, such as a liquid helium film3, which cannot condense at
non-zero temperature although it becomes superfluid above a critical phase space
density. The quasi-long-range coherence and the microscopic nature of the BKT
transition were recently explored with ultracold atomic gases4,5,6. However, a
direct observation of superfluidity in terms of frictionless flow is still missing
for these systems. Here we probe the superfluidity of a 2D trapped Bose gas using
a moving obstacle formed by a micrometre-sized laser beam. We find a dramatic
variation of the response of the fluid, depending on its degree of degeneracy
at the obstacle location.

text: The computer vision and pattern recognition communities have recently witnessed
a surge in feature-based methods for numerous applications including object recognition
and image retrieval. Similar concepts and analogous approaches are penetrating
the world of 3D shape analysis in a variety of areas including non-rigid shape
retrieval and matching. In this chapter, we present both mature concepts and the
state-of-the-art of feature-based approaches in 3D shape analysis. In particular,
approaches to the detection of interest points and the generation of local shape
descriptors are discussed. A wide range of methods is covered including those
based on curvature, those based on difference-of-Gaussian scale space, and those
that employ recent advances in heat kernel methods.

text: Similarity and correspondence are two fundamental archetype problems in shape
analysis, encountered in numerous application in computer vision and pattern recognition.
Many methods for shape similarity and correspondence boil down to the minimum-distortion
correspondence problem, in which two shapes are endowed with certain structure,
and one attempts to find the matching with smallest structure distortion between
them. Defining structures invariant to some class of shape transformations results
in an invariant minimum-distortion correspondence or similarity. In this paper,
we model shapes using local and global structures, formulate the invariant correspondence
problem as binary graph labeling, and show how different choice of structure results
in invariance under various classes of deformations.

text: Finding a match between partially available deformable shapes is a challenging
problem with numerous applications. The problem is usually approached by computing
local descriptors on a pair of shapes and then establishing a point-wise correspondence
between the two. In this paper, we introduce an alternative correspondence-less
approach to matching fragments to an entire shape undergoing a non-rigid deformation.
We use diffusion geometric 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 meshes. Experiments
demonstrating the success of the proposed method are presented.

text: In this paper, we explore the use of the diffusion geometry framework for
the fusion of geometric and photometric information in local heat kernel signature
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: 'Analysis of intrinsic symmetries of non-rigid and articulated shapes is an
important problem in pattern recognition with numerous applications ranging from
medicine to computational aesthetics. Considering articulated planar shapes as
closed curves, we show how to represent their extrinsic and intrinsic symmetries
as self-similarities of local descriptor sequences, which in turn have simple
interpretation in the frequency domain. The problem of symmetry detection and
analysis thus boils down to analysis of descriptor sequence patterns. For that
purpose, we show two efficient computational methods: one based on Fourier analysis,
and another on dynamic programming.'

text: In classical signal processing, it is common to analyze and process signals
in the frequency domain, by representing the signal in the Fourier basis, and
filtering it by applying a transfer function on the Fourier coefficients. In some
applications, it is possible to design an optimal filter. A classical example
is the Wiener filter that achieves a minimum mean squared error estimate for signal
denoising. Here, we adopt similar concepts to construct optimal diffusion geometric
shape descriptors. The analogy of Fourier basis are the eigenfunctions of the
Laplace-Beltrami operator, in which many geometric constructions such as diffusion
metrics, can be represented. By designing a filter of the Laplace-Beltrami eigenvalues,
it is theoretically possible to achieve invariance to different shape transformations,
like scaling. Given a set of shape classes with different transformations, we
learn the optimal filter by minimizing the ratio between knowingly similar and
knowingly dissimilar diffusion distances it induces. The output of the proposed
framework is a filter that is optimally tuned to handle transformations that characterize
the training set.

text: Understanding of articulated shape motion plays an important role in many
applications in the mechanical engineering, movie industry, graphics, and vision
communities. In this paper, we study motion-based segmentation of articulated
3D shapes into rigid parts. We pose the problem as finding a group-valued map
between the shapes describing the motion, forcing it to favor piecewise rigid
motions. Our computation follows the spirit of the Ambrosio-Tortorelli scheme
for Mumford-Shah segmentation, with a diffusion component suited for the group
nature of the motion model. Experimental results demonstrate the effectiveness
of the proposed method in non-rigid motion segmentation.

text: Multi-part shape matching is an important class of problems, arising in many
fields such as computational archaeology, biology, geometry processing, computer
graphics and vision. In this paper, we address the problem of simultaneous matching
and segmentation of multiple shapes. We assume to be given a reference shape and
multiple parts partially matching the reference. Each of these parts can have
additional clutter, have overlap with other parts, or there might be missing parts.
We show experimental results of efficient and accurate assembly of fractured synthetic
and real objects.

text: "We present a novel method for estimation of articulated motion in depth scans.
The method is based on a framework for regularization of vector- and matrix- valued
functions on parametric surfaces.\r\n\r\nWe extend augmented-Lagrangian total
variation regularization to smooth rigid motion cues on the scanned 3D surface
obtained from a range scanner. We demonstrate the resulting smoothed motion maps
to be a powerful tool in articulated scene understanding, providing a basis for
rigid parts segmentation, with little prior assumptions on the scene, despite
the noisy depth measurements that often appear in commodity depth scanners."

text: The rapid development of 3D acquisition technology has brought with itself
the need to perform standard signal processing operations such as filters on 3D
data. It has been shown that the eigenfunctions of the Laplace-Beltrami operator
(manifold harmonics) of a surface play the role of the Fourier basis in the Euclidean
space; it is thus possible to formulate signal analysis and synthesis in the manifold
harmonics basis. In particular, geometry filtering can be carried out in the manifold
harmonics domain by decomposing the embedding coordinates of the shape in this
basis. However, since the basis functions depend on the shape itself, such filtering
is valid only for weak (near all-pass) filters, and produces severe artifacts
otherwise. In this paper, we analyze this problem and propose the fractional filtering
approach, wherein we apply iteratively weak fractional powers of the filter, followed
by the update of the basis functions. Experimental results show that such a process
produces more plausible and meaningful results.

text: We introduce an (equi-)affine invariant geometric structure by which surfaces
that go through squeeze and shear transformations can still be properly analyzed.
The definition of an affine invariant metric enables us to evaluate a new form
of geodesic distances and to construct an invariant Laplacian from which local
and global diffusion geometry is constructed. Applications of the proposed framework
demonstrate its power in generalizing and enriching the existing set of tools
for shape analysis.

text: Region feature detectors and descriptors have become a successful and popular
alternative to point descriptors in image analysis due to their high robustness
and repeatability, leading to a significant interest in the shape analysis community
in finding analogous approaches in the 3D world. Recent works have successfully
extended the maximally stable extremal region (MSER) detection algorithm to surfaces.
In many applications, however, a volumetric shape model is more appropriate, and
modeling shape deformations as approximate isometries of the volume of an object,
rather than its boundary, better captures natural behavior of non-rigid deformations.
In this paper, we formulate a diffusion-geometric framework for volumetric stable
component detection and description in deformable shapes. An evaluation of our
method on the SHREC'11 feature detection benchmark and SCAPE human body scans
shows 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 work, we present intrinsic shape context (ISC) descriptors for 3D
shapes. We generalize to surfaces the polar sampling of the image domain used
in shape contexts: for this purpose, we chart the surface by shooting geodesic
outwards from the point being analyzed; `angle'' is treated as tantamount to geodesic
shooting direction, and radius as geodesic distance. To deal with orientation
ambiguity, we exploit properties of the Fourier transform. Our charting method
is intrinsic, i.e., invariant to isometric shape transformations. The resulting
descriptor is a meta-descriptor that can be applied to any photometric or geometric
property field defined on the shape, in particular, we can leverage recent developments
in intrinsic shape analysis and construct ISC based on state-of-the-art dense
shape descriptors such as heat kernel signatures. Our experiments demonstrate
a notable improvement in shape matching on standard benchmarks.'

text: We consider the problem of minimum distortion intrinsic correspondence between
deformable shapes, many useful formulations of which give rise to the NP-hard
quadratic assignment problem (QAP). Previous attempts to use the spectral relaxation
have had limited success due to the lack of sparsity of the obtained “fuzzy” solution.
In this paper, we adopt the recently introduced alternative L 1 relaxation of
the QAP based on the principles of game theory. We relate it to the Gromov and
Lipschitz metrics between metric spaces and demonstrate on state-of-the-art benchmarks
that the proposed approach is capable of finding very accurate sparse correspondences
between deformable shapes.

text: SIFT-like local feature descriptors are ubiquitously employed in computer
vision applications such as content-based retrieval, video analysis, copy detection,
object recognition, photo tourism, and 3D reconstruction. Feature descriptors
can be designed to be invariant to certain classes of photometric and geometric
transformations, in particular, affine and intensity scale transformations. However,
real transformations that an image can undergo can only be approximately modeled
in this way, and thus most descriptors are only approximately invariant in practice.
Second, descriptors are usually high dimensional (e.g., SIFT is represented as
a 128--dimensional vector). In large-scale retrieval and matching problems, this
can pose challenges in storing and retrieving descriptor data. We map the descriptor
vectors into the Hamming space in which the Hamming metric is used to compare
the resulting representations. This way, we reduce the size of the descriptors
by representing them as short binary strings and learn descriptor invariance from
examples. We show extensive experimental validation, demonstrating the advantage
of the proposed approach.
