text: Nuclear pore complexes (NPCs) form gateways that control molecular exchange
between the nucleus and the cytoplasm. They impose a diffusion barrier to macromolecules
and enable the selective transport of nuclear transport receptors with bound cargo.
The underlying mechanisms that establish these permeability properties remain
to be fully elucidated but require unstructured nuclear pore proteins rich in
Phe-Gly (FG)-repeat domains of different types, such as FxFG and GLFG. While physical
modeling and in vitro approaches have provided a framework for explaining how
the FG network contributes to the barrier and transport properties of the NPC,
it remains unknown whether the number and/or the spatial positioning of different
FG-domains along a cylindrical, ∼40 nm diameter transport channel contributes
to their collective properties and function. To begin to answer these questions,
we have used DNA origami to build a cylinder that mimics the dimensions of the
central transport channel and can house a specified number of FG-domains at specific
positions with easily tunable design parameters, such as grafting density and
topology. We find the overall morphology of the FG-domain assemblies to be dependent
on their chemical composition, determined by the type and density of FG-repeat,
and on their architectural confinement provided by the DNA cylinder, largely consistent
with here presented molecular dynamics simulations based on a coarse-grained polymer
model. In addition, high-speed atomic force microscopy reveals local and reversible
FG-domain condensation that transiently occludes the lumen of the DNA central
channel mimics, suggestive of how the NPC might establish its permeability properties.

text: "Owing to their wide tunability, multiple internal degrees of freedom, and
low disorder, graphene heterostructures are emerging as a promising experimental
platform for fractional quantum Hall (FQH) studies. Here, we report FQH thermal
activation gap measurements in dual graphite-gated monolayer graphene devices
fabricated in an edgeless Corbino geometry. In devices with substrate-induced
sublattice splitting, we find a tunable crossover between single- and multicomponent
FQH states in the zero energy Landau level. Activation gaps in the single-component
regime show excellent agreement with numerical calculations using a single broadening
parameter \r\nΓ≈7.2K. In the first excited Landau level, in contrast, FQH gaps
are strongly influenced by Landau level mixing, and we observe an unexpected valley-ordered
state at integer filling ν=−4."

text: 'The superconducting state of matter enables one to observe quantum effects
on the macroscopic scale and hosts many fascinating phenomena. Topological defects
of the superconducting order parameter, such as vortices and fluxoid states in
multiply connected structures, are often the key ingredients of these phenomena.
This dissertation describes a new mode of magnetic force microscopy (Φ0-MFM) for
investigating vortex and fluxoid sates in mesoscopic superconducting (SC) structures.
The technique relies on the magneto-mechanical coupling of a MFM cantilever to
the motion of fluxons. The novelty of the technique is that a magnetic particle
attached to the cantilever is used not only to sense the state of a SC structure,
but also as a primary source of the inhomogeneous magnetic field which induces
that state. Φ0-MFM enables us to map the transitions between tip-induced states
during a scan: at the positions of the tip, where the two lowest energy states
become degenerate, small oscillations of the tip drive the transitions between
these states, which causes a significant shift in the resonant frequency and dissipation
of the cantilever. For narrow-wall aluminum rings, the mapped fluxoid transitions
form concentric contours on a scan. We show that the changes in the cantilever
resonant frequency and dissipation are well-described by a stochastic resonance
(SR) of cantilever-driven thermally activated phase slips (TAPS). The SR model
allows us to experimentally determine the rate of TAPS and compare it to the Langer-Ambegaokar-McCumber-Halperin
(LAMH) theory for TAPS in 1D superconducting structures. Further, we use the SR
model to qualitatively study the effects of a locally applied magnetic field on
the phase slip rate in rings containing constrictions. The states with multiple
vortices or winding numbers could be useful for the development of novel superconducting
devices, or the study of vortex interactions and interference effects. Using Φ0-MFM
allows us to induce, probe and control fluxoid states in thin wall structures
comprised of multiple loops. We show that Φ0-MFM images of the fluxoid transitions
allow us to identify the underlying states and to investigate their energetics
and dynamics even in complicated structures.'

text: Premature aging disorders provide an opportunity to study the mechanisms that
drive aging. In Hutchinson-Gilford progeria syndrome (HGPS), a mutant form of
the nuclear scaffold protein lamin A distorts nuclei and sequesters nuclear proteins.
We sought to investigate protein homeostasis in this disease. Here, we report
a widespread increase in protein turnover in HGPS-derived cells compared to normal
cells. We determine that global protein synthesis is elevated as a consequence
of activated nucleoli and enhanced ribosome biogenesis in HGPS-derived fibroblasts.
Depleting normal lamin A or inducing mutant lamin A expression are each sufficient
to drive nucleolar expansion. We further show that nucleolar size correlates with
donor age in primary fibroblasts derived from healthy individuals and that ribosomal
RNA production increases with age, indicating that nucleolar size and activity
can serve as aging biomarkers. While limiting ribosome biogenesis extends lifespan
in several systems, we show that increased ribosome biogenesis and activity are
a hallmark of premature aging.

text: Solid‐state NMR spectroscopy can provide insight into protein structure and
dynamics at the atomic level without inherent protein size limitations. However,
a major hurdle to studying large proteins by solid‐state NMR spectroscopy is related
to spectral complexity and resonance overlap, which increase with molecular weight
and severely hamper the assignment process. Here the use of two sets of experiments
is shown to expand the tool kit of 1H‐detected assignment approaches, which correlate
a given amide pair either to the two adjacent CO–CA pairs (4D hCOCANH/hCOCAcoNH),
or to the amide 1H of the neighboring residue (3D HcocaNH/HcacoNH, which can be
extended to 5D). The experiments are based on efficient coherence transfers between
backbone atoms using INEPT transfers between carbons and cross‐polarization for
heteronuclear transfers. The utility of these experiments is exemplified with
application to assemblies of deuterated, fully amide‐protonated proteins from
approximately 20 to 60 kDa monomer, at magic‐angle spinning (MAS) frequencies
from approximately 40 to 55 kHz. These experiments will also be applicable to
protonated proteins at higher MAS frequencies. The resonance assignment of a domain
within the 50.4 kDa bacteriophage T5 tube protein pb6 is reported, and this is
compared to NMR assignments of the isolated domain in solution. This comparison
reveals contacts of this domain to the core of the polymeric tail tube assembly.

text: 'Solid-state NMR spectroscopy can provide site-resolved information about
protein dynamics over many time scales. Here we combine protein deuteration, fast
magic-angle spinning (~45–60 kHz) and proton detection to study dynamics of ubiquitin
in microcrystals, and in particular a mutant in a region that undergoes microsecond
motions in a β-turn region in the wild-type protein. We use 15N R1ρ relaxation
measurements as a function of the radio-frequency (RF) field strength, i.e. relaxation
dispersion, to probe how the G53A mutation alters these dynamics. We report a
population-inversion of conformational states: the conformation that in the wild-type
protein is populated only sparsely becomes the predominant state. We furthermore
explore the potential to use amide-1H R1ρ relaxation to obtain insight into dynamics.
We show that while quantitative interpretation of 1H relaxation remains beyond
reach under the experimental conditions, due to coherent contributions to decay,
one may extract qualitative information about flexibility.'

text: We present an improved fast mixing device based on the rapid mixing of two
solutions inside the NMR probe, as originally proposed by Hore and coworkers (J.
Am. Chem. Soc. 125 (2003) 12484–12492). Such a device is important for off-equilibrium
studies of molecular kinetics by multidimensional real-time NMR spectrsocopy.
The novelty of this device is that it allows removing the injector from the NMR
detection volume after mixing, and thus provides good magnetic field homogeneity
independently of the initial sample volume placed in the NMR probe. The apparatus
is simple to build, inexpensive, and can be used without any hardware modification
on any type of liquid-state NMR spectrometer. We demonstrate the performance of
our fast mixing device in terms of improved magnetic field homogeneity, and show
an application to the study of protein folding and the structural characterization
of transiently populated folding intermediates.

text: High-harmonic spectroscopy driven by circularly polarized laser pulses and
their counterrotating second harmonic is a new branch of attosecond science which
currently lacks quantitative interpretations. We extend this technique to the
midinfrared regime and record detailed high-harmonic spectra of several rare-gas
atoms. These results are compared with the solution of the Schrödinger equation
in three dimensions and calculations based on the strong-field approximation that
incorporate accurate scattering-wave recombination matrix elements. A quantum-orbit
analysis of these results provides a transparent interpretation of the measured
intensity ratios of symmetry-allowed neighboring harmonics in terms of (i) a set
of propensity rules related to the angular momentum of the atomic orbitals, (ii)
atom-specific matrix elements related to their electronic structure, and (iii)
the interference of the emissions associated with electrons in orbitals corotating
or counterrotating with the laser fields. These results provide the foundation
for a quantitative understanding of bicircular high-harmonic spectroscopy.

text: Strong-field photoelectron holography and laser-induced electron diffraction
(LIED) are two powerful emerging methods for probing the ultrafast dynamics of
molecules. However, both of them have remained restricted to static systems and
to nuclear dynamics induced by strong-field ionization. Here we extend these promising
methods to image purely electronic valence-shell dynamics in molecules using photoelectron
holography. In the same experiment, we use LIED and photoelectron holography simultaneously,
to observe coupled electronic-rotational dynamics taking place on similar timescales.
These results offer perspectives for imaging ultrafast dynamics of molecules on
femtosecond to attosecond timescales.

text: We present a theoretical formalism for the calculation of attosecond delays
in molecular photoionization. It is shown how delays relevant to one-photon-ionization,
also known as Eisenbud-Wigner-Smith delays, can be obtained from the complex dipole
matrix elements provided by molecular quantum scattering theory. These results
are used to derive formulae for the delays measured by two-photon attosecond interferometry
based on an attosecond pulse train and a dressing femtosecond infrared pulse.
These effective delays are first expressed in the molecular frame where maximal
information about the molecular photoionization dynamics is available. The effects
of averaging over the emission direction of the electron and the molecular orientation
are introduced analytically. We illustrate this general formalism for the case
of two polyatomic molecules. N2O serves as an example of a polar linear molecule
characterized by complex photoionization dynamics resulting from the presence
of molecular shape resonances. H2O illustrates the case of a non-linear molecule
with comparably simple photoionization dynamics resulting from a flat continuum.
Our theory establishes the foundation for interpreting measurements of the photoionization
dynamics of all molecules by attosecond metrology.

text: High-harmonic spectroscopy driven by circularly polarized laser pulses and
their counterrotating second harmonic is a new branch of attosecond science which
currently lacks quantitative interpretations. We extend this technique to the
midinfrared regime and record detailed high-harmonic spectra of several rare-gas
atoms. These results are compared with the solution of the Schrödinger equation
in three dimensions and calculations based on the strong-field approximation that
incorporate accurate scattering-wave recombination matrix elements. A quantum-orbit
analysis of these results provides a transparent interpretation of the measured
intensity ratios of symmetry-allowed neighboring harmonics in terms of (i) a set
of propensity rules related to the angular momentum of the atomic orbitals, (ii)
atom-specific matrix elements related to their electronic structure, and (iii)
the interference of the emissions associated with electrons in orbitals corotating
or counterrotating with the laser fields. These results provide the foundation
for a quantitative understanding of bicircular high-harmonic spectroscopy.

text: 'Cellular membranes exhibit a large variety of shapes, strongly coupled to
their function. Many biological processes involve dynamic reshaping of membranes,
usually mediated by proteins. This interaction works both ways: while proteins
influence the membrane shape, the membrane shape affects the interactions between
the proteins. To study these membrane-mediated interactions on closed and anisotropically
curved membranes, we use colloids adhered to ellipsoidal membrane vesicles as
a model system. We find that two particles on a closed system always attract each
other, and tend to align with the direction of largest curvature. Multiple particles
form arcs, or, at large enough numbers, a complete ring surrounding the vesicle
in its equatorial plane. The resulting vesicle shape resembles a snowman. Our
results indicate that these physical interactions on membranes with anisotropic
shapes can be exploited by cells to drive macromolecules to preferred regions
of cellular or intracellular membranes, and utilized to initiate dynamic processes
such as cell division. The same principle could be used to find the midplane of
an artificial vesicle, as a first step towards dividing it into two equal parts.'

text: "Spatiotemporal activation of RhoA and actomyosin contraction underpins cellular
adhesion and division. Loss of cell–cell adhesion and chromosomal instability
are cardinal events that drive tumour progression. Here, we show that p120-catenin
(p120) not only controls cell–cell adhesion, but also acts as a critical regulator
of cytokinesis. We find that p120 regulates actomyosin contractility through concomitant
binding to RhoA and the centralspindlin component MKLP1, independent of cadherin
association. In anaphase, p120 is enriched at the cleavage furrow where it binds
MKLP1 to spatially control RhoA GTPase cycling. Binding of p120 to MKLP1 during
cytokinesis depends on the N-terminal coiled-coil domain of p120 isoform 1A. Importantly,
clinical data show that loss of p120 expression is a common event in breast cancer
that strongly correlates with multinucleation and adverse patient survival. In
summary, our study identifies p120 loss as a driver event of chromosomal instability
in cancer.\r\n"

text: Azobenzenealkanethiols in self-assembled monolayers (SAMs) on Au(111) exhibit
reversible trans–cis photoisomerization when diluted with alkanethiol spacers.
Using these mixed SAMs, we show switching of the linear optical and second-harmonic
response. The effective switching of these surface optical properties relies on
a reasonably large cross section and a high photoisomerization yield as well as
a long lifetime of the metastable cis isomer. We quantified the switching process
by X-ray absorption spectroscopy. The cross sections for the trans–cis and cis–trans
photoisomerization with 365 and 455 nm light, respectively, are 1 order of magnitude
smaller than in solution. In vacuum, the 365 nm photostationary state comprises
50–74% of the molecules in the cis form, limited by their rapid thermal isomerization
back to the trans state. In contrast, the 455 nm photostationary state contains
nearly 100% trans-azobenzene. We determined time constants for the thermal cis–trans
isomerization of only a few minutes in vacuum and in a dry nitrogen atmosphere
but of more than 1 day in ambient air. Our results suggest that adventitious water
adsorbed on the surface of the SAM stabilizes the polar cis configuration of azobenzene
under ambient conditions. The back reaction rate constants differing by 2 orders
of magnitude underline the huge influence of the environment and, accordingly,
its importance when comparing various experiments.

text: Come on in, the water's fine! Non-photoresponsive nanoparticles can be reversibly
assembled using light by placing them in an aqueous solution of a photoacid.
Upon exposure to visible light, the photoacid reduces the pH of the solution,
which induces attractive interactions between the nanoparticles. In the dark,
the resulting nanoparticle aggregates spontaneously disassemble. The process can
be repeated many times.

text: Au25 nanoclusters functionalized with a spiropyran molecular switch are synthesized
via a ligand-exchange reaction at low temperature. The resulting nanoclusters
are characterized by optical and NMR spectroscopies as well as by mass spectrometry.
Spiropyran bound to nanoclusters isomerizes in a reversible fashion when exposed
to UV and visible light, and its properties are similar to those of free spiropyran
molecules in solution. The reversible photoisomerization entails the modulation
of fluorescence as well as the light-controlled self-assembly of nanoclusters.

text: We report measurements of energy-dependent attosecond photoionization delays
between the two outer-most valence shells of N2O and H2O. The combination of single-shot
signal referencing with the use of different metal foils to filter the attosecond
pulse train enables us to extract delays from congested spectra. Remarkably large
delays up to 160 as are observed in N2O, whereas the delays in H2O are all smaller
than 50 as in the photon-energy range of 20-40 eV. These results are interpreted
by developing a theory of molecular photoionization delays. The long delays measured
in N2O are shown to reflect the population of molecular shape resonances that
trap the photoelectron for a duration of up to ∼110 as. The unstructured continua
of H2O result in much smaller delays at the same photon energies. Our experimental
and theoretical methods make the study of molecular attosecond photoionization
dynamics accessible.

text: We introduce bicircular high-harmonic spectroscopy as a new method to probe
dynamical symmetries of atoms and molecules and their evolution in time. Our approach
is based on combining a circularly polarized femtosecond fundamental field of
frequency ω with its counterrotating second harmonic 2ω. We demonstrate the ability
of bicircular high-harmonic spectroscopy to characterize the orbital angular momentum
symmetry of atomic orbitals. We further show that breaking the threefold rotational
symmetry of the generating medium-at the level of either the ensemble or that
of a single molecule-results in the emission of the otherwise parity-forbidden
frequencies 3qω (q∈N), which provide a background-free probe of dynamical molecular
symmetries.
