text: Single-molecule conductance studies have traditionally focused on creating
highly conducting molecular wires. However, progress in nanoscale electronics
demands insulators just as it needs conductors. Here we describe the single-molecule
length-dependent conductance properties of the classic silicon dioxide insulator.
We synthesize molecular wires consisting of Si–O repeat units and measure their
conductance through the scanning tunneling microscope-based break-junction method.
These molecules yield conductance lower than alkanes of the same length and the
largest length-dependent conductance decay of any molecular systems measured to
date. We calculate single-molecule junction transmission and the complex band
structure of the infinite 1D material for siloxane, in comparison with silane
and alkane, and show that the large conductance decay is intrinsic to the nature
of the Si–O bond. This work highlights the potential for siloxanes to function
as molecular insulators in electronics.

text: How heteroatomic substitutions affect electron transport through π-conjugated
hydrocarbons has been the subject of some debate. In this paper we investigate
the effect of heteroatomic linkers in a molecular junction on the electron-transmission
spectrum, focusing on the occurrence of quantum interference (QI) close to the
Fermi level, where conductivity can be significantly suppressed. We find that
the substitution or addition of heteroatoms to a carbon skeleton at the contact
positions does not change the main feature of QI due to the underlying carbon
skeleton. QI in the overall system thus remains a robust feature. This empirical
observation leads us to derive, in two mathematical ways, that these findings
can be generalized. We note that addition or substitution of a carbon atom by
a heteroatom at the contact positions will increase or decrease the number of
electrons in the π-system, which will lead to a change in the alignment of the
molecular orbitals of the isolated system relative to the electrode Fermi level.
Both Hückel and density functional theory calculations on model systems probe
the effect of this Fermi level change and confirm qualitatively the implications
of the underlying mathematical proofs.

text: Quantum interference effects, whether constructive or destructive, are key
to predicting and understanding the electrical conductance of single molecules.
Here, through theory and experiment, we investigate a family of benzene-like molecules
that exhibit both constructive and destructive interference effects arising due
to more than one contact between the molecule and each electrode. In particular,
we demonstrate that the π-system of meta-coupled benzene can exhibit constructive
interference and its para-coupled analog can exhibit destructive interference,
and vice versa, depending on the specific through-space interactions. As a peculiarity,
this allows a meta-coupled benzene molecule to exhibit higher conductance than
a para-coupled benzene. Our results provide design principles for molecular electronic
components with high sensitivity to through-space interactions and demonstrate
that increasing the number of contacts between the molecule and electrodes can
both increase and decrease the conductance.

text: "This Account provides an overview of our recent efforts to uncover the fundamental
charge transport properties of Si–Si and Ge–Ge single bonds and introduce useful
functions into group 14 molecular wires. We utilize the tools of chemical synthesis
and a scanning tunneling microscopy-based break-junction technique to study the
mechanism of charge transport in these molecular systems. We evaluated the fundamental
ability of silicon, germanium, and carbon molecular wires to transport charge
by comparing conductances within families of well-defined structures, the members
of which differ only in the number of Si (or Ge or C) atoms in the wire. For each
family, this procedure yielded a length-dependent conductance decay parameter,
β. Comparison of the different β values demonstrates that Si–Si and Ge–Ge σ bonds
are more conductive than the analogous C–C σ bonds. These molecular trends mirror
what is seen in the bulk.\r\n\r\nThe conductance decay of Si and Ge-based wires
is similar in magnitude to those from π-based molecular wires such as paraphenylenes
However, the chemistry of the linkers that attach the molecular wires to the electrodes
has a large influence on the resulting β value. For example, Si- and Ge-based
wires of many different lengths connected with a methyl–thiomethyl linker give
β values of 0.36–0.39 Å–1, whereas Si- and Ge-based wires connected with aryl–thiomethyl
groups give drastically different β values for short and long wires. This observation
inspired us to study molecular wires that are composed of both π- and σ-orbitals.
The sequence and composition of group 14 atoms in the σ chain modulates the electronic
coupling between the π end-groups and dictates the molecular conductance. The
conductance behavior originates from the coupling between the subunits, which
can be understood by considering periodic trends such as bond length, polarizability,
and bond polarity.\r\n\r\nWe found that the same periodic trends determine the
electric field-induced breakdown properties of individual Si–Si, Ge–Ge, Si–O,
Si–C, and C–C bonds. Building from these studies, we have prepared a system that
has two different, alternative conductance pathways. In this wire, we can intentionally
break a labile, strained silicon–silicon bond and thereby shunt the current through
the secondary conduction pathway. This type of in situ bond-rupture provides a
new tool to study single molecule reactions that are induced by electric fields.
Moreover, these studies provide guidance for designing dielectric materials as
well as molecular devices that require stability under high voltage bias.\r\n\r\nThe
fundamental studies on the structure/function relationships of the molecular wires
have guided the design of new functional systems based on the Si- and Ge-based
wires. For example, we exploited the principle of strain-induced Lewis acidity
from reaction chemistry to design a single molecule switch that can be controllably
switched between two conductive states by varying the distance between the tip
and substrate electrodes. We found that the strain intrinsic to the disilaacenaphthene
scaffold also creates two state conductance switching. Finally, we demonstrate
the first example of a stereoelectronic conductance switch, and we demonstrate
that the switching relies crucially on the electronic delocalization in Si–Si
and Ge–Ge wire backbones. These studies illustrate the untapped potential in using
Si- and Ge-based wires to design and control charge transport at the nanoscale
and to allow quantum mechanics to be used as a tool to design ultraminiaturized
switches."

text: The electronic, mechanical, and thermoelectric properties of molecular scale
devices have fascinated scientists across several disciplines in natural sciences
and engineering. The interest is partially technological, driven by the fast miniaturization
of integrated circuits that now have reached characteristic features at the nanometer
scale. Equally important, a very strong incentive also exists to elucidate the
fundamental aspects of structure-function relations for nanoscale devices, which
utilize molecular building blocks as functional units. Thus motivated, a rich
research field has established itself, broadly termed “Molecular Electronics,”
that hosts a plethora of activities devoted to this goal in chemistry, physics,
and electrical engineering. This Special Topic on Frontiers of Molecular Scale
Electronics captures recent theoretical and experimental advances in the field.

text: We perform temperature dependent conductance measurements on sub-nanometer
sized single molecules bound to gold electrodes using a scanning tunneling microscope-based
break junction technique in Ultra-High Vacuum (UHV). We find a threefold increase
in the conductance of amine-terminated conjugated molecules when the temperature
increases from 4 K to 300 K in UHV. Furthermore, the conductance measured at 300
K in UHV is consistent with solution-based measurements under ambient conditions
where the transport mechanism corresponds to off-resonant electron tunneling across
the molecule. Our measurements indicate that at 300 K, conductance is largely
independent of pressure or solvent around the junction. In addition, our data
unambiguously show that temperature can affect the tunneling conductance of single
molecule-metal junctions. We show that the structure of the metal electrodes that
form in these junctions varies systematically with temperature, and hypothesize
that this changing structure of the interface alters electron tunneling probability
and propose a mechanism to explain our findings.

text: We investigate light-induced conductance enhancement in single-molecule junctions
via photon-assisted transport and hot-electron transport. Using 4,4′-bipyridine
bound to Au electrodes as a prototypical single-molecule junction, we report a
20–40% enhancement in conductance under illumination with 980 nm wavelength radiation.
We probe the effects of subtle changes in the transmission function on light-enhanced
current and show that discrete variations in the binding geometry result in a
10% change in enhancement. Importantly, we prove theoretically that the steady-state
behavior of photon-assisted transport and hot-electron transport is identical
but that hot-electron transport is the dominant mechanism for optically induced
conductance enhancement in single-molecule junctions when the wavelength used
is absorbed by the electrodes and the hot-electron relaxation time is long. We
confirm this experimentally by performing polarization-dependent conductance measurements
of illuminated 4,4′-bipyridine junctions. Finally, we perform lock-in type measurements
of optical current and conclude that currents due to laser-induced thermal expansion
mask optical currents. This work provides a robust experimental framework for
studying mechanisms of light-enhanced transport in single-molecule junctions and
offers tools for tuning the performance of organic optoelectronic devices by analyzing
detailed transport properties of the molecules involved.

text: Single-molecule electronic devices provide researchers with an unprecedented
ability to relate novel physical phenomena to molecular chemical structures. Typically,
conjugated aromatic molecular backbones are relied upon to create electronic devices,
where the aromaticity of the building blocks is used to enhance conductivity.
We capitalize on the classical physical organic chemistry concept of Hückel antiaromaticity
by demonstrating a single-molecule switch that exhibits low conductance in the
neutral state and, upon electrochemical oxidation, reversibly switches to an antiaromatic
high-conducting structure. We form single-molecule devices using the scanning
tunneling microscope–based break-junction technique and observe an on/off ratio
of ~70 for a thiophenylidene derivative that switches to an antiaromatic state
with 6-4-6-π electrons. Through supporting nuclear magnetic resonance measurements,
we show that the doubly oxidized core has antiaromatic character and we use density
functional theory calculations to rationalize the origin of the high-conductance
state for the oxidized single-molecule junction. Together, our work demonstrates
how the concept of antiaromaticity can be exploited to create single-molecule
devices that are highly conducting.

text: Whilst most studies in single-molecule electronics involve components first
synthesized ex situ, there is also great potential in exploiting chemical transformations
to prepare devices in situ. Here, as a first step towards this goal, we conduct
reversible reactions on monolayers to make and break covalent bonds between alkanes
of different lengths, then measure the conductance of these molecules connected
between electrodes using the scanning tunneling microscopy-based break junction
(STM-BJ) method. In doing so, we develop the critical methodology required for
assembling and disassembling surface-bound single-molecule circuits. We identify
effective reaction conditions for surface-bound reagents, and importantly demonstrate
that the electronic characteristics of wires created in situ agree with those
created ex situ. Finally, we show that the STM-BJ technique is unique in its ability
to definitively probe surface reaction yields both on a local (∼50 nm2) and pseudo-global
(≥10 mm2) level. This investigation thus highlights a route to the construction
and integration of more complex, and ultimately functional, surface-based single-molecule
circuitry, as well as advancing a methodology that facilitates studies beyond
the reach of traditional ex situ synthetic approaches.

text: Thiophene-1,1-dioxide (TDO) oligomers have fascinating electronic properties.
We previously used thermopower measurements to show that a change in charge carrier
from hole to electron occurs with increasing length of TDO oligomers when single-molecule
junctions are formed between gold electrodes. In this article, we show for the
first time that the dominant conducting orbitals for thiophene/TDO oligomers of
fixed length can be tuned by altering the strength of the electron acceptors incorporated
into the backbone. We use the scanning tunneling microscope break-junction (STM-BJ)
technique and apply a recently developed method to determine the dominant transport
channel in single-molecule junctions formed with these systems. Through these
measurements, we find that increasing the electron affinity of thiophene derivatives,
within a family of pentamers, changes the polarity of the charge carriers systematically
from holes to electrons, with some systems even showing mid-gap transport characteristics.

text: Higgs and Goldstone modes are collective excitations of the amplitude and
phase of an order parameter that is related to the breaking of a continuous symmetry.
We directly studied these modes in a supersolid quantum gas created by coupling
a Bose-Einstein condensate to two optical cavities, whose field amplitudes form
the real and imaginary parts of a U(1)-symmetric order parameter. Monitoring the
cavity fields in real time allowed us to observe the dynamics of the associated
Higgs and Goldstone modes and revealed their amplitude and phase nature. We used
a spectroscopic method to measure their frequencies, and we gave a tunable mass
to the Goldstone mode by exploring the crossover between continuous and discrete
symmetry. Our experiments link spectroscopic measurements to the theoretical concept
of Higgs and Goldstone modes.

text: 'The concept of a supersolid state combines the crystallization of a many-body
system with dissipationless flow of the atoms from which it is built. This quantum
phase requires the breaking of two continuous symmetries: the phase invariance
of a superfluid and the continuous translational invariance to form the crystal1,2.
Despite having been proposed for helium almost 50 years ago3,4, experimental verification
of supersolidity remains elusive5,6. A variant with only discrete translational
symmetry breaking on a preimposed lattice structure—the ‘lattice supersolid’7—has
been realized, based on self-organization of a Bose–Einstein condensate8,9. However,
lattice supersolids do not feature the continuous ground-state degeneracy that
characterizes the supersolid state as originally proposed. Here we report the
realization of a supersolid with continuous translational symmetry breaking along
one direction in a quantum gas. The continuous symmetry that is broken emerges
from two discrete spatial symmetries by symmetrically coupling a Bose–Einstein
condensate to the modes of two optical cavities. We establish the phase coherence
of the supersolid and find a high ground-state degeneracy by measuring the crystal
position over many realizations through the light fields that leak from the cavities.
These light fields are also used to monitor the position fluctuations in real
time. Our concept provides a route to creating and studying glassy many-body systems
with controllably lifted ground-state degeneracies, such as supersolids in the
presence of disorder.'

text: We introduce a new framework for learning dense correspondence between deformable
3D shapes. Existing learning based approaches model shape correspondence as a
labelling problem, where each point of a query shape receives a label identifying
a point on some reference domain; the correspondence is then constructed a posteriori
by composing the label predictions of two input shapes. We propose a paradigm
shift and design a structured prediction model in the space of functional maps,
linear operators that provide a compact representation of the correspondence.
We model the learning process via a deep residual network which takes dense descriptor
fields defined on two shapes as input, and outputs a soft map between the two
given objects. The resulting correspondence is shown to be accurate on several
challenging benchmarks comprising multiple categories, synthetic models, real
scans with acquisition artifacts, topological noise, and partiality.

text: Many algorithms for the computation of correspondences between deformable
shapes rely on some variant of nearest neighbor matching in a descriptor space.
Such are, for example, various point-wise correspondence recovery algorithms used
as a post-processing stage in the functional correspondence framework. Such frequently
used techniques implicitly make restrictive assumptions (e.g., nearisometry) on
the considered shapes and in practice suffer from lack of accuracy and result
in poor surjectivity. We propose an alternative recovery technique capable of
guaranteeing a bijective correspondence and producing significantly higher accuracy
and smoothness. Unlike other methods our approach does not depend on the assumption
that the analyzed shapes are isometric. We derive the proposed method from the
statistical framework of kernel density estimation and demonstrate its performance
on several challenging deformable 3D shape matching datasets.

text: The increasing demand for high image quality in mobile devices brings forth
the need for better computational enhancement techniques, and image denoising
in particular. To this end, we propose a new fully convolutional deep neural network
architecture which is simple yet powerful and achieves state-of-the-art performance
for additive Gaussian noise removal. Furthermore, we claim that the personal photo-collections
can usually be categorized into a small set of semantic classes. However simple,
this observation has not been exploited in image denoising until now. We show
that a significant boost in performance of up to 0.4dB PSNR can be achieved by
making our network class-aware, namely, by fine-tuning it for images belonging
to a specific semantic class. Relying on the hugely successful existing image
classifiers, this research advocates for using a class-aware approach in all image
enhancement tasks.

text: Multidimensional Scaling (MDS) is one of the most popular methods for dimensionality
reduction and visualization of high dimensional data. Apart from these tasks,
it also found applications in the field of geometry processing for the analysis
and reconstruction of non-rigid shapes. In this regard, MDS can be thought of
as a shape from metric algorithm, consisting of finding a configuration of points
in the Euclidean space that realize, as isometrically as possible, some given
distance structure. In the present work we cast the least squares variant of MDS
(LS-MDS) in the spectral domain. This uncovers a multiresolution property of distance
scaling which speeds up the optimization by a significant amount, while producing
comparable, and sometimes even better, embeddings.

text: With increasingly sophisticated Diffusion Weighted MRI acquisition methods
and modeling techniques, very large sets of streamlines (fibers) are presently
generated per imaged brain. These reconstructions of white matter architecture,
which are important for human brain research and pre-surgical planning, require
a large amount of storage and are often unwieldy and difficult to manipulate and
analyze. This work proposes a novel continuous parsimonious framework in which
signals are sparsely represented in a dictionary with continuous atoms. The significant
innovation in our new methodology is the ability to train such continuous dictionaries,
unlike previous approaches that either used pre-fixed continuous transforms or
training with finite atoms. This leads to an innovative fiber representation method,
which uses Continuous Dictionary Learning to sparsely code each fiber with high
accuracy. This method is tested on numerous tractograms produced from the Human
Connectome Project data and achieves state-of-the-art performances in compression
ratio and reconstruction error.

text: We present ASIST, a technique for transforming point clouds by replacing objects
with their semantically equivalent counterparts. Transformations of this kind
have applications in virtual reality, repair of fused scans, and robotics. ASIST
is based on a unified formulation of semantic labeling and object replacement;
both result from minimizing a single objective. We present numerical tools for
the efficient solution of this optimization problem. The method is experimentally
assessed on new datasets of both synthetic and real point clouds, and is additionally
compared to two recent works on object replacement on data from the corresponding
papers.

text: The sliding clamp, PCNA, plays a central role in DNA replication and repair.
In the moving replication fork, PCNA is present at the leading strand and at each
of the Okazaki fragments that are formed on the lagging strand. PCNA enhances
the processivity of the replicative polymerases and provides a landing platform
for other proteins and enzymes. The loading of the clamp onto DNA is performed
by the Replication Factor C (RFC) complex, whereas its unloading can be carried
out by an RFC-like complex containing Elg1. Mutations in ELG1 lead to DNA damage
sensitivity and genome instability. To characterize the role of Elg1 in maintaining
genomic integrity, we used homology modeling to generate a number of site-specific
mutations in ELG1 that exhibit different PCNA unloading capabilities. We show
that the sensitivity to DNA damaging agents and hyper-recombination of these alleles
correlate with their ability to unload PCNA from the chromatin. Our results indicate
that retention of modified and unmodified PCNA on the chromatin causes genomic
instability. We also show, using purified proteins, that the Elg1 complex inhibits
DNA synthesis by unloading SUMOylated PCNA from the DNA. Additionally, we find
that mutations in ELG1 suppress the sensitivity of rad5Δ mutants to DNA damage
by allowing trans-lesion synthesis to take place. Taken together, the data indicate
that the Elg1–RLC complex plays an important role in the maintenance of genomic
stability by unloading PCNA from the chromatin.

text: Recent studies validated the feasibility of estimating heart rate from human
faces in RGB video. However, test subjects are often recorded under controlled
conditions, as illumination variations significantly affect the RGB-based heart
rate estimation accuracy. Intel newly-announced low-cost RealSense 3D (RGBD) camera
is becoming ubiquitous in laptops and mobile devices starting this year, opening
the door to new and more robust computer vision. RealSense cameras produce RGB
images with extra depth information inferred from a latent near-infrared (NIR)
channel. In this paper, we experimentally demonstrate, for the first time, that
heart rate can be reliably estimated from RealSense near-infrared images. This
enables illumination invariant heart rate estimation, extending the heart rate
from video feasibility to low-light applications, such as night driving. With
the (coming) ubiquitous presence of RealSense devices, the proposed method not
only utilizes its near-infrared channel, designed originally to be hidden from
consumers; but also exploits the associated depth information for improved robustness
to head pose.
