text: We fabricate and characterize a microscale silicon opto-electromechanical
system whose mechanical motion is coupled capacitively to an electrical circuit
and optically via radiation pressure to a photonic crystal cavity. To achieve
large electromechanical interaction strength, we implement an inverse shadow mask
fabrication scheme which obtains capacitor gaps as small as 30 nm while maintaining
a silicon surface quality necessary for minimizing optical loss. Using the sensitive
optical read-out of the photonic crystal cavity, we characterize the linear and
nonlinear capacitive coupling to the fundamental ωm=2π = 63 MHz in-plane flexural
motion of the structure, showing that the large electromechanical coupling in
such devices may be suitable for realizing efficient microwave-to-optical signal
conversion.

text: Intellectual disability (ID) has an estimated prevalence of 2-3%. Due to its
extreme heterogeneity, the genetic basis of ID remains elusive in many cases.
Recently, whole exome sequencing (WES) studies revealed that a large proportion
of sporadic cases are caused by de novo gene variants. To identify further genes
involved in ID, we performed WES in 250 patients with unexplained ID and their
unaffected parents and included exomes of 51 previously sequenced child-parents
trios in the analysis. Exome analysis revealed de novo intragenic variants in
SET domain-containing 5 (SETD5) in two patients. One patient carried a nonsense
variant, and the other an 81 bp deletion located across a splice-donor site. Chromosomal
microarray diagnostics further identified four de novo non-recurrent microdeletions
encompassing SETD5. CRISPR/Cas9 mutation modelling of the two intragenic variants
demonstrated nonsense-mediated decay of the resulting transcripts, pointing to
a loss-of-function (LoF) and haploinsufficiency as the common disease-causing
mechanism of intragenic SETD5 sequence variants and SETD5-containing microdeletions.
In silico domain prediction of SETD5, a predicted SET domain-containing histone
methyltransferase (HMT), substantiated the presence of a SET domain and identified
a novel putative PHD domain, strengthening a functional link to well-known histone-modifying
ID genes. All six patients presented with ID and certain facial dysmorphisms,
suggesting that SETD5 sequence variants contribute substantially to the microdeletion
3p25.3 phenotype. The present report of two SETD5 LoF variants in 301 patients
demonstrates a prevalence of 0.7% and thus SETD5 variants as a relatively frequent
cause of ID.

text: Motivated by recent ideas of Harman (Unif. Distrib. Theory, 2010) we develop
a new concept of variation of multivariate functions on a compact Hausdorff space
with respect to a collection D of subsets. We prove a general version of the Koksma-Hlawka
theorem that holds for this notion of variation and discrepancy with respect to
D. As special cases, we obtain Koksma-Hlawka inequalities for classical notions,
such as extreme or isotropic discrepancy. For extreme discrepancy, our result
coincides with the usual Koksma-Hlawka theorem. We show that the space of functions
of bounded D-variation contains important discontinuous functions and is closed
under natural algebraic operations. Finally, we illustrate the results on concrete
integration problems from integral geometry and stereology.

text: We present a software platform for reconstructing and analyzing the growth
of a plant root system from a time-series of 3D voxelized shapes. It aligns the
shapes with each other, constructs a geometric graph representation together with
the function that records the time of growth, and organizes the branches into
a hierarchy that reflects the order of creation. The software includes the automatic
computation of structural and dynamic traits for each root in the system enabling
the quantification of growth on fine-scale. These are important advances in plant
phenotyping with applications to the study of genetic and environmental influences
on growth.

text: 'We investigate bidirectional femtosecond charge transfer dynamics using the
core–hole clock implementation of resonant photoemission spectroscopy from 4,4′-bipyridine
molecular layers on three different surfaces: Au(111), epitaxial graphene on Ni(111),
and graphene nanoribbons. We show that the lowest unoccupied molecular orbital
(LUMO) of the molecule drops partially below the Fermi level upon core–hole creation
in all systems, opening an additional decay channel for the core–hole, involving
electron donation from substrate to the molecule. Furthermore, using the core–hole
clock method, we find that the bidirectional charge transfer time between the
substrate and the molecule is fastest on Au(111), with a 2 fs time, then around
4 fs for epitaxial graphene and slowest with graphene nanoribbon surface, taking
around 10 fs. Finally, we provide evidence for fast phase decoherence of the core-excited
LUMO* electron through an interaction with the substrate providing the first observation
of such a fast bidirectional charge transfer across an organic/graphene interface.'

text: We report a systematic computational search of molecular frameworks for intrinsic
rectification of electron transport. The screening of molecular rectifiers includes
52 molecules and conformers spanning over 9 series of structural motifs. N-Phenylbenzamide
is found to be a promising framework with both suitable conductance and rectification
properties. A targeted screening performed on 30 additional derivatives and conformers
of N-phenylbenzamide yielded enhanced rectification based on asymmetric functionalization.
We demonstrate that electron-donating substituent groups that maintain an asymmetric
distribution of charge in the dominant transport channel (e.g., HOMO) enhance
rectification by raising the channel closer to the Fermi level. These findings
are particularly valuable for the design of molecular assemblies that could ensure
directionality of electron transport in a wide range of applications, from molecular
electronics to catalytic reactions.

text: While the electrical conductivity of bulk-scale group 14 materials such as
diamond carbon, silicon, and germanium is well understood, there is a gap in knowledge
regarding the conductivity of these materials at the nano and molecular scales.
Filling this gap is important because integrated circuits have shrunk so far that
their active regions, which rely so heavily on silicon and germanium, begin to
resemble ornate molecules rather than extended solids. Here we unveil a new approach
for synthesizing atomically discrete wires of germanium and present the first
conductance measurements of molecular germanium using a scanning tunneling microscope-based
break-junction (STM-BJ) technique. Our findings show that germanium and silicon
wires are nearly identical in conductivity at the molecular scale, and that both
are much more conductive than aliphatic carbon. We demonstrate that the strong
donor ability of C–Ge σ-bonds can be used to raise the energy of the anchor lone
pair and increase conductance. Furthermore, the oligogermane wires behave as conductance
switches that function through stereoelectronic logic. These devices can be trained
to operate with a higher switching factor by repeatedly compressing and elongating
the molecular junction.

text: Recent experiments have shown that transport properties of molecular-scale
devices can be reversibly altered by the surrounding solvent. Here, we use a combination
of first-principles calculations and experiment to explain this change in transport
properties through a shift in the local electrostatic potential at the junction
caused by nearby conducting and solvent molecules chemically bound to the electrodes.
This effect is found to alter the conductance of 4,4′-bipyridine-gold junctions
by more than 50%. Moreover, we develop a general electrostatic model that quantitatively
relates the conductance and dipoles associated with the bound solvent and conducting
molecules. Our work shows that solvent-induced effects can be used to control
charge and energy transport at molecular-scale interfaces.

text: Charge transport properties of metal–molecule interfaces depend strongly on
the character of molecule–electrode interactions. Although through-bond coupled
systems have attracted the most attention, through-space coupling is important
in molecular systems when, for example, through-bond coupling is suppressed due
to quantum interference effects. To date, a probe that clearly distinguishes these
two types of coupling has not yet been demonstrated. Here, we investigate the
origin of flicker noise in single molecule junctions and demonstrate how the character
of the molecule–electrode coupling influences the flicker noise behavior of single
molecule junctions. Importantly, we find that flicker noise shows a power law
dependence on conductance in all junctions studied with an exponent that can distinguish
through-space and through-bond coupling. Our results provide a new and powerful
tool for probing and understanding coupling at the metal-molecule interface.

text: We study the impact of electrode band structure on transport through single-molecule
junctions by measuring the conductance of pyridine-based molecules using Ag and
Au electrodes. Our experiments are carried out using the scanning tunneling microscope
based break-junction technique and are supported by density functional theory
based calculations. We find from both experiments and calculations that the coupling
of the dominant transport orbital to the metal is stronger for Au-based junctions
when compared with Ag-based junctions. We attribute this difference to relativistic
effects, which result in an enhanced density of d-states at the Fermi energy for
Au compared with Ag. We further show that the alignment of the conducting orbital
relative to the Fermi level does not follow the work function difference between
two metals and is different for conjugated and saturated systems. We thus demonstrate
that the details of the molecular level alignment and electronic coupling in metal–organic
interfaces do not follow simple rules but are rather the consequence of subtle
local interactions.

text: Molecular electronics aims to miniaturize electronic devices by using subnanometre-scale
active components1,2,3. A single-molecule diode, a circuit element that directs
current flow4, was first proposed more than 40 years ago5 and consisted of an
asymmetric molecule comprising a donor–bridge–acceptor architecture to mimic a
semiconductor p–n junction. Several single-molecule diodes have since been realized
in junctions featuring asymmetric molecular backbones6,7,8, molecule–electrode
linkers9 or electrode materials10. Despite these advances, molecular diodes have
had limited potential for applications due to their low conductance, low rectification
ratios, extreme sensitivity to the junction structure and high operating voltages7,8,9,11,12.
Here, we demonstrate a powerful approach to induce current rectification in symmetric
single-molecule junctions using two electrodes of the same metal, but breaking
symmetry by exposing considerably different electrode areas to an ionic solution.
This allows us to control the junction's electrostatic environment in an asymmetric
fashion by simply changing the bias polarity. With this method, we reliably and
reproducibly achieve rectification ratios in excess of 200 at voltages as low
as 370 mV using a symmetric oligomer of thiophene-1,1-dioxide13,14. By taking
advantage of the changes in the junction environment induced by the presence of
an ionic solution, this method provides a general route for tuning nonlinear nanoscale
device phenomena, which could potentially be applied in systems beyond single-molecule
junctions.

text: Here we study the stability and rupture of molecular junctions under high
voltage bias at the single molecule/single bond level using the scanning tunneling
microscope-based break-junction technique. We synthesize carbon-, silicon-, and
germanium-based molecular wires terminated by aurophilic linker groups and study
how the molecular backbone and linker group affect the probability of voltage-induced
junction rupture. First, we find that junctions formed with covalent S–Au bonds
are robust under high voltage and their rupture does not demonstrate bias dependence
within our bias range. In contrast, junctions formed through donor–acceptor bonds
rupture more frequently, and their rupture probability demonstrates a strong bias
dependence. Moreover, we find that the junction rupture probability increases
significantly above ∼1 V in junctions formed from methylthiol-terminated disilanes
and digermanes, indicating a voltage-induced rupture of individual Si–Si and Ge–Ge
bonds. Finally, we compare the rupture probabilities of the thiol-terminated silane
derivatives containing Si–Si, Si–C, and Si–O bonds and find that Si–C backbones
have higher probabilities of sustaining the highest voltage. These results establish
a new method for studying electric field breakdown phenomena at the single molecule
level.

text: A new intersection between reaction chemistry and electronic circuitry is
emerging from the ultraminiaturization of electronic devices. Over decades chemists
have developed a nuanced understanding of stereoelectronics to establish how the
electronic properties of molecules relate to their conformation; the recent advent
of single-molecule break-junction techniques provides the means to alter this
conformation with a level of control previously unimagined. Here we unite these
ideas by demonstrating the first single-molecule switch that operates through
a stereoelectronic effect. We demonstrate this behaviour in permethyloligosilanes
with methylthiomethyl electrode linkers. The strong σ conjugation in the oligosilane
backbone couples the stereoelectronic properties of the sulfur–methylene σ bonds
that terminate the molecule. Theoretical calculations support the existence of
three distinct dihedral conformations that differ drastically in their electronic
character. We can shift between these three species by simply lengthening or compressing
the molecular junction, and, in doing so, we can switch conductance digitally
between two states.

text: To develop advanced materials for electronic devices, it is of utmost importance
to design organic building blocks with tunable functionality and to study their
properties at the molecular level. For organic electronic and photovoltaic applications,
the ability to vary the nature of charge carriers and so create either electron
donors or acceptors is critical. Here we demonstrate that charge carriers in single-molecule
junctions can be tuned within a family of molecules that contain electron-deficient
thiophene-1,1-dioxide (TDO) building blocks. Oligomers of TDO were designed to
increase electron affinity and maintain delocalized frontier orbitals while significantly
decreasing the transport gap. Through thermopower measurements we show that the
dominant charge carriers change from holes to electrons as the number of TDO units
is increased. This results in a unique system in which the charge carrier depends
on the backbone length, and provides a new means to tune p- and n-type transport
in organic materials.

text: Noncoding variants in the human MIR137 gene locus increase schizophrenia risk
with genome-wide significance. However, the functional consequence of these risk
alleles is unknown. Here we examined induced human neurons harboring the minor
alleles of four disease-associated single nucleotide polymorphisms in MIR137.
We observed increased MIR137 levels compared to those in major allele–carrying
cells. microRNA-137 gain of function caused downregulation of the presynaptic
target genes complexin-1 (Cplx1), Nsf and synaptotagmin-1 (Syt1), leading to impaired
vesicle release. In vivo, miR-137 gain of function resulted in changes in synaptic
vesicle pool distribution, impaired induction of mossy fiber long-term potentiation
and deficits in hippocampus-dependent learning and memory. By sequestering endogenous
miR-137, we were able to ameliorate the synaptic phenotypes. Moreover, reinstatement
of Syt1 expression partially restored synaptic plasticity, demonstrating the importance
of Syt1 as a miR-137 target. Our data provide new insight into the mechanism by
which miR-137 dysregulation can impair synaptic plasticity in the hippocampus.

text: Repeated stress has been suggested to underlie learning and memory deficits
via the basolateral amygdala (BLA) and the hippocampus; however, the functional
contribution of BLA inputs to the hippocampus and their molecular repercussions
are not well understood. Here we show that repeated stress is accompanied by generation
of the Cdk5 (cyclin-dependent kinase 5)-activator p25, up-regulation and phosphorylation
of glucocorticoid receptors, increased HDAC2 expression, and reduced expression
of memoryrelated genes in the hippocampus. A combination of optogenetic and pharmacosynthetic
approaches shows that BLA activation is both necessary and sufficient for stress-associated
molecular changes and memory impairments. Furthermore, we show that this effect
relies on direct glutamatergic projections from the BLA to the dorsal hippocampus.
Finally, we show that p25 generation is necessary for the stress-induced memory
dysfunction. Taken together, our data provide a neural circuit model for stress-induced
hippocampal memory deficits through BLA activity-dependent p25 generation.

text: It is known that in classical fluids turbulence typically occurs at high Reynolds
numbers. But can turbulence occur at low Reynolds numbers? Here we investigate
the transition to turbulence in the classic Taylor-Couette system in which the
rotating fluids are manufactured ferrofluids with magnetized nanoparticles embedded
in liquid carriers. We find that, in the presence of a magnetic field transverse
to the symmetry axis of the system, turbulence can occur at Reynolds numbers that
are at least one order of magnitude smaller than those in conventional fluids.
This is established by extensive computational ferrohydrodynamics through a detailed
investigation of transitions in the flow structure, and characterization of behaviors
of physical quantities such as the energy, the wave number, and the angular momentum
through the bifurcations. A finding is that, as the magnetic field is increased,
onset of turbulence can be determined accurately and reliably. Our results imply
that experimental investigation of turbulence may be feasible by using ferrofluids.
Our study of transition to and evolution of turbulence in the Taylor-Couette ferrofluidic
flow system provides insights into the challenging problem of turbulence control.

text: 'We consider the problem of deciding whether the persistent homology group
of a simplicial pair (K,L) can be realized as the homology H∗(X) of some complex
X with L ⊂ X ⊂ K. We show that this problem is NP-complete even if K is embedded
in double-struck R3. As a consequence, we show that it is NP-hard to simplify
level and sublevel sets of scalar functions on double-struck S3 within a given
tolerance constraint. This problem has relevance to the visualization of medical
images by isosurfaces. We also show an implication to the theory of well groups
of scalar functions: not every well group can be realized by some level set, and
deciding whether a well group can be realized is NP-hard.'
