text: Brains are thought to engage in predictive learning - learning to predict
upcoming stimuli - to construct an internal model of their environment. This is
especially notable for spatial navigation, as first described by Tolman’s latent
learning tasks. However, predictive learning has also been observed in sensory
cortex, in settings unrelated to spatial navigation. Apart from normative frameworks
such as active inference or efficient coding, what could be the utility of learning
to predict the patterns of occurrence of correlated stimuli? Here we show that
prediction, and thereby the construction of an internal model of sequential stimuli,
can bootstrap the learning process of a working memory task in a recurrent neural
network. We implemented predictive learning alongside working memory match-tasks,
and networks emerged to solve the prediction task first by encoding information
across time to predict upcoming stimuli, and then eavesdropped on this solution
to solve the matching task. Eavesdropping was most beneficial when neural resources
were limited. Hence, predictive learning acts as a general neural mechanism to
learn to store sensory information that can later be essential for working memory
tasks.

text: Ustilago maydis is a biotrophic phytopathogenic fungus that causes corn smut
disease. As a well-established model system, U. maydis is genetically fully accessible
with large omics datasets available and subject to various biological questions
ranging from DNA-repair, RNA-transport, and protein secretion to disease biology.
For many genetic approaches, tight control of transgene regulation is important.
Here we established an optimised version of the Tetracycline-ON (TetON) system
for U. maydis. We demonstrate the Tetracycline concentration-dependent expression
of fluorescent protein transgenes and the system’s suitability for the induced
expression of the toxic protein BCL2 Associated X-1 (Bax1). The Golden Gate compatible
vector system contains a native minimal promoter from the mating factor a-1 encoding
gene, mfa with ten copies of the tet-regulated operator (tetO) and a codon optimised
Tet-repressor (tetR*) which is translationally fused to the native transcriptional
corepressor Mql1 (UMAG_05501). The metabolism-independent transcriptional regulator
system is functional both, in liquid culture as well as on solid media in the
presence of the inducer and can become a useful tool for toxin-antitoxin studies,
identification of antifungal proteins, and to study functions of toxic gene products
in Ustilago maydis.

text: Addressing fairness concerns about machine learning models is a crucial step
towards their long-term adoption in real-world automated systems. Many approaches
for training fair models from data have been developed and an implicit assumption
about such algorithms is that they are able to recover a fair model, despite potential
historical biases in the data. In this work we show a number of impossibility
results that indicate that there is no learning algorithm that can recover a fair
model when a proportion of the dataset is subject to arbitrary manipulations.
Specifically, we prove that there are situations in which an adversary can force
any learner to return a biased classifier, with or without degrading accuracy,
and that the strength of this bias increases for learning problems with underrepresented
protected groups in the data. Our results emphasize on the importance of studying
further data corruption models of various strength and of establishing stricter
data collection practices for fairness-aware learning.

text: The self-assembly of inorganic nanoparticles (NPs) into ordered structures
(superlattices) has led to a wide range of nanomaterials with unique optical,
magnetic, electronic, and catalytic properties. Various interactions have been
employed to direct the crystallization of NPs, including van der Waals forces,
hydrogen bonding, as well as electric and magnetic dipolar interactions. Among
them, Coulombic interactions—ubiquitous in nature and the main driving force behind
the formation of many minerals, such as fluorite or rock salt—have remained largely
underexplored, owing to the rapid charge exchange between NPs bearing high densities
of opposite charges (superionic NPs). Here, we worked with superionic NPs under
conditions (room temperature, concentrated salt solutions) that preserved their
native surface charge density. We demonstrate that under these conditions, the
Coulombic interactions between superionic NPs are reminiscent of short-range intermolecular
interactions. Our methodology was used to assemble oppositely charged NPs into
high-quality superlattices exhibiting Catalan shapes. Depending on their size
ratio, the NPs assembled into either rhombic dodecahedra or triakis tetrahedra
with structures mimicking those of the ionic solids CsCl and Th3P4, respectively.
We envision that the methodology described here can be applied to a wide range
of charged NPs of various sizes, shapes, and compositions, thus facilitating the
discovery of new nanomaterials.

text: Confining molecules within well-defined nanosized spaces can profoundly alter
their physicochemical characteristics. For example, the controlled aggregation
of chromophores into discrete oligomers has been shown to tune their optical properties
whereas encapsulation of reactive species within molecular hosts can increase
their stability. The resazurin/resorufin pair has been widely used for detecting
redox processes in biological settings; yet, how tight confinement affects the
properties of these two dyes remains to be explored. Here, we show that a flexible
PdII6L4 coordination
cage can efficiently encapsulate both resorufin and resazurin in the form of dimers,
dramatically modulating their optical properties. Furthermore, binding within
the cage significantly decreases the reduction rate of resazurin to resorufin,
and the rate of the subsequent reduction of resorufin to dihydroresorufin. During
our studies, we also found that upon dilution, the PdII6L4
cage disassembles to afford PdII2L2
species, which lacks the ability to form inclusion complexes – a process that
can be reversed upon the addition of the strongly binding resorufin/resazurin
guests. We expect that the herein disclosed ability of a water-soluble cage to
reversibly modulate the optical and chemical properties of a molecular redox probe
will expand the versatility of synthetic fluorescent probes in biologically relevant
environments.

text: Molecular confinement effects can profoundly alter the physicochemical properties
of the confined species. A plethora of organic molecules were encapsulated within
the cavities of supramolecular hosts, and the impact of the cavity size and polarity
was widely investigated. However, the extent to which the properties of the confined
guests can be affected by the symmetry of the cage─which dictates the shape of
the cavity─remains to be understood. Here we show that cage symmetry has a dramatic
effect on the equilibrium between two isomers of the encapsulated spiropyran guests.
Working with two Pd-based coordination cages featuring similarly sized but differently
shaped hydrophobic cavities, we found a highly selective stabilization of the
isomer whose shape matches that of the cavity of the cage. A Td-symmetric cage
stabilized the spiropyrans’ colorless form and rendered them photochemically inert.
In contrast, a D2h-symmetric cage favored the colored isomer, while maintaining
reversible photoswitching between the two states of the encapsulated spiropyrans.
We also show that the switching kinetics strongly depend on the substitution pattern
on the spiropyran scaffold. This finding was used to fabricate a time-sensitive
information storage medium with tunable lifetimes of the encoded messages.

text: Confinement within molecular cages can dramatically modify the physicochemical
properties of the encapsulated guest molecules, but such host-guest complexes
have mainly been studied in a static context. Combining confinement effects with
fast guest exchange kinetics could pave the way toward stimuli-responsive supramolecular
systems—and ultimately materials—whose desired properties could be tailored “on
demand” rapidly and reversibly. Here, we demonstrate rapid guest exchange between
inclusion complexes of an open-window coordination cage that can simultaneously
accommodate two guest molecules. Working with two types of guests, anthracene
derivatives and BODIPY dyes, we show that the former can substantially modify
the optical properties of the latter upon noncovalent heterodimer formation. We
also studied the light-induced covalent dimerization of encapsulated anthracenes
and found large effects of confinement on reaction rates. By coupling the photodimerization
with the rapid guest exchange, we developed a new way to modulate fluorescence
using external irradiation.

text: Optoelectronic effects differentiating absorption of right and left circularly
polarized photons in thin films of chiral materials are typically prohibitively
small for their direct photocurrent observation. Chiral metasurfaces increase
the electronic sensitivity to circular polarization, but their out-of-plane architecture
entails manufacturing and performance trade-offs. Here, we show that nanoporous
thin films of chiral nanoparticles enable high sensitivity to circular polarization
due to light-induced polarization-dependent ion accumulation at nanoparticle interfaces.
Self-assembled multilayers of gold nanoparticles modified with L-phenylalanine
generate a photocurrent under right-handed circularly polarized light as high
as 2.41 times higher than under left-handed circularly polarized light. The strong
plasmonic coupling between the multiple nanoparticles producing planar chiroplasmonic
modes facilitates the ejection of electrons, whose entrapment at the membrane–electrolyte
interface is promoted by a thick layer of enantiopure phenylalanine. Demonstrated
detection of light ellipticity with equal sensitivity at all incident angles mimics
phenomenological aspects of polarization vision in marine animals. The simplicity
of self-assembly and sensitivity of polarization detection found in optoionic
membranes opens the door to a family of miniaturized fluidic devices for chiral
photonics.

text: We show that the optical properties of indigo carmine can be modulated by
encapsulation within a coordination cage. Depending on the host/guest molar ratio,
the cage can predominantly encapsulate either one or two dye molecules. The 1 : 1
complex is fluorescent, unique for an indigo dye in an aqueous solution. We have
also found that binding two dye molecules stabilizes a previously unknown conformation
of the cage.

text: 'Supramolecular self-assembly in biological systems holds promise to convert
and amplify disease-specific signals to physical or mechanical signals that can
direct cell fate. However, it remains challenging to design physiologically stable
self-assembling systems that demonstrate tunable and predictable behavior. Here,
the use of zwitterionic tetrapeptide modalities to direct nanoparticle assembly
under physiological conditions is reported. The self-assembly of gold nanoparticles
can be activated by enzymatic unveiling of surface-bound zwitterionic tetrapeptides
through matrix metalloprotease-9 (MMP-9), which is overexpressed by cancer cells.
This robust nanoparticle assembly is achieved by multivalent, self-complementary
interactions of the zwitterionic tetrapeptides. In cancer cells that overexpress
MMP-9, the nanoparticle assembly process occurs near the cell membrane and causes
size-induced selection of cellular uptake mechanism, resulting in diminished cell
growth. The enzyme responsiveness, and therefore, indirectly, the uptake route
of the system can be programmed by customizing the peptide sequence: a simple
inversion of the two amino acids at the cleavage site completely inactivates the
enzyme responsiveness, self-assembly, and consequently changes the endocytic pathway.
This robust self-complementary, zwitterionic peptide design demonstrates the use
of enzyme-activated electrostatic side-chain patterns as powerful and customizable
peptide modalities to program nanoparticle self-assembly and alter cellular response
in biological context.'

text: Rotation is typically assumed to induce strictly symmetric rotational splitting
into the rotational multiplets of pure p- and g-modes. However, for evolved stars
exhibiting mixed modes, avoided crossings between different multiplet components
are known to yield asymmetric rotational splitting, in particular for near-degenerate
mixed-mode pairs, where notional pure p-modes are fortuitously in resonance with
pure g-modes. These near-degeneracy effects have been described in subgiants,
but their consequences for the characterization of internal rotation in red giants
have not previously been investigated in detail, in part owing to theoretical
intractability. We employ new developments in the analytic theory of mixed-mode
coupling to study these near-resonance phenomena. In the vicinity of the most
p-dominated mixed modes, the near-degenerate intrinsic asymmetry from pure rotational
splitting increases dramatically over the course of stellar evolution, and it
depends strongly on the mode-mixing fraction ζ. We also find that a linear treatment
of rotation remains viable for describing the underlying p- and g-modes, even
when it does not for the resulting mixed modes undergoing these avoided crossings.
We explore observational consequences for potential measurements of asymmetric
mixed-mode splitting, which has been proposed as a magnetic-field diagnostic.
Finally, we propose improved measurement techniques for rotational characterization,
exploiting the linearity of rotational effects on the underlying p/g-modes, while
still accounting for these mixed-mode coupling effects.

text: 'We characterize massive stars (M > 8 M⊙) in the nearby (D ∼ 0.8 Mpc) extremely
metal-poor (Z ∼ 5% Z⊙) galaxy Leo A using Hubble Space Telescope ultraviolet (UV),
optical, and near-infrared (NIR) imaging along with Keck/Low-Resolution Imaging
Spectrograph and MMT/Binospec optical spectroscopy for 18 main-sequence OB stars.
We find that: (a) 12 of our 18 stars show emission lines, despite not being associated
with an H ii region, suggestive of stellar activity (e.g., mass loss, accretion,
binary star interaction), which is consistent with previous predictions of enhanced
activity at low metallicity; (b) six are Be stars, which are the first to be spectroscopically
studied at such low metallicity—these Be stars have unusual panchromatic SEDs;
(c) for stars well fit by the TLUSTY nonlocal thermodynamic equilibrium models,
the photometric and spectroscopic values of $\mathrm{log}({T}_{\mathrm{eff}})$
and $\mathrm{log}(g)$ agree to within ∼0.01 dex and ∼0.18 dex, respectively, indicating
that near-UV/optical/NIR imaging can be used to reliably characterize massive
(M ∼ 8–30 M⊙) main-sequence star properties relative to optical spectroscopy;
(d) the properties of the most-massive stars in H II regions are consistent with
constraints from previous nebular emission line studies; and (e) 13 stars with
M > 8M⊙ are >40 pc from a known star cluster or H II region. Our sample comprises
∼50% of all known massive stars at Z ≲ 10% Z⊙with derived stellar parameters,
high-quality optical spectra, and panchromatic photometry.'

text: Magnetic fields can drastically change predictions of evolutionary models
of massive stars via mass-loss quenching, magnetic braking, and efficient angular
momentum transport, which we aim to quantify in this work. We use the MESA software
instrument to compute an extensive main-sequence grid of stellar structure and
evolution models, as well as isochrones, accounting for the effects attributed
to a surface fossil magnetic field. The grid is densely populated in initial mass
(3–60 M⊙), surface equatorial magnetic field strength (0–50 kG), and metallicity
(representative of the Solar neighbourhood and the Magellanic Clouds). We use
two magnetic braking and two chemical mixing schemes and compare the model predictions
for slowly rotating, nitrogen-enriched (‘Group 2’) stars with observations in
the Large Magellanic Cloud. We quantify a range of initial field strengths that
allow for producing Group 2 stars and find that typical values (up to a few kG)
lead to solutions. Between the subgrids, we find notable departures in surface
abundances and evolutionary paths. In our magnetic models, chemical mixing is
always less efficient compared to non-magnetic models due to the rapid spin-down.
We identify that quasi-chemically homogeneous main sequence evolution by efficient
mixing could be prevented by fossil magnetic fields. We recommend comparing this
grid of evolutionary models with spectropolarimetric and spectroscopic observations
with the goals of (i) revisiting the derived stellar parameters of known magnetic
stars, and (ii) observationally constraining the uncertain magnetic braking and
chemical mixing schemes.

text: The prediction and realization of topological insulators have sparked great
interest in experimental approaches to the classification of materials1,2,3. The
phase transition between non-trivial and trivial topological states is important,
not only for basic materials science but also for next-generation technology,
such as dissipation-free electronics4. It is therefore crucial to develop advanced
probes that are suitable for a wide range of samples and environments. Here we
demonstrate that circularly polarized laser-field-driven high-harmonic generation
is distinctly sensitive to the non-trivial and trivial topological phases in the
prototypical three-dimensional topological insulator bismuth selenide5. The phase
transition is chemically initiated by reducing the spin–orbit interaction strength
through the substitution of bismuth with indium atoms6,7. We find strikingly different
high-harmonic responses of trivial and non-trivial topological surface states
that manifest themselves as a conversion efficiency and elliptical dichroism that
depend both on the driving laser ellipticity and the crystal orientation. The
origins of the anomalous high-harmonic response are corroborated by calculations
using the semiconductor optical Bloch equations with pairs of surface and bulk
bands. As a purely optical approach, this method offers sensitivity to the electronic
structure of the material, including its nonlinear response, and is compatible
with a wide range of samples and sample environments.

text: Understanding the chirality of molecular reaction pathways is essential for
a broad range of fundamental and applied sciences. However, the current ability
to probe chirality on the time scale of primary processes underlying chemical
reactions remains very limited. Here, we demonstrate time-resolved photoelectron
circular dichroism (TRPECD) with ultrashort circularly polarized vacuum-ultraviolet
(VUV) pulses from a tabletop source. We demonstrate the capabilities of VUV-TRPECD
by resolving the chirality changes in time during the photodissociation of atomic
iodine from two chiral molecules. We identify several general key features of
TRPECD, which include the ability to probe dynamical chirality along the complete
photochemical reaction path, the sensitivity to the local chirality of the evolving
scattering potential, and the influence of electron scattering off dissociating
photofragments. Our results are interpreted by comparison with high-level ab-initio
calculations of transient PECDs from molecular photoionization calculations. Our
experimental and theoretical techniques define a general approach to femtochirality.

text: Photoionization is a process taking place on attosecond time scales. How its
properties evolve from isolated particles to the condensed phase is an open question
of both fundamental and practical relevance. Here, we review recent work that
has advanced the study of photoionization dynamics from atoms to molecules, clusters
and the liquid phase. The first measurements of molecular photoionization delays
have revealed the attosecond dynamics of electron emission from a molecular shape
resonance and their sensitivity to the molecular potential. Using electron-ion
coincidence spectroscopy these measurements have been extended from isolated molecules
to clusters. A continuous increase of the delays with the water-cluster size has
been observed up to a size of 4-5 molecules, followed by a saturation towards
larger clusters. Comparison with calculations has revealed a correlation of the
time delay with the spatial extension of the created electron hole. Using cylindrical
liquid-microjet techniques, these measurements have also been extended to liquid
water, revealing a delay relative to isolated water molecules that was very similar
to the largest water clusters studied. Detailed modeling based on Monte-Carlo
simulations confirmed that these delays are dominated by the contributions of
the first two solvation shells, which agrees with the results of the cluster measurements.
These combined results open the perspective of experimentally characterizing the
delocalization of electronic wave functions in complex systems and studying their
evolution on attosecond time scales.

text: "Ultrafast lasers are an increasingly important tool to control and stabilize
emergent phases in quantum materials. Among a variety of possible excitation protocols,
a particularly intriguing route is the direct light engineering of microscopic
electronic parameters, such as the electron hopping and the local Coulomb repulsion
(Hubbard \r\nU). In this work, we use time-resolved x-ray absorption spectroscopy
to demonstrate the light-induced renormalization of the Hubbard U in a cuprate
superconductor, La1.905Ba0.095CuO4. We show that intense femtosecond laser pulses
induce a substantial redshift of the upper Hubbard band while leaving the Zhang-Rice
singlet energy unaffected. By comparing the experimental data to time-dependent
spectra of single- and three-band Hubbard models, we assign this effect to an
approximately 140-meV reduction of the on-site Coulomb repulsion on the copper
sites. Our demonstration of a dynamical Hubbard U renormalization in a copper
oxide paves the way to a novel strategy for the manipulation of superconductivity
and magnetism as well as to the realization of other long-range-ordered phases
in light-driven quantum materials."

text: ' We propose a stochastic conditional gradient method (CGM) for minimizing
convex finite-sum objectives formed as a sum of smooth and non-smooth terms. Existing
CGM variants for this template either suffer from slow convergence rates, or require
carefully increasing the batch size over the course of the algorithm’s execution,
which leads to computing full gradients. In contrast, the proposed method, equipped
with a stochastic average gradient (SAG) estimator, requires only one sample per
iteration. Nevertheless, it guarantees fast convergence rates on par with more
sophisticated variance reduction techniques. In applications we put special emphasis
on problems with a large number of separable constraints. Such problems are prevalent
among semidefinite programming (SDP) formulations arising in machine learning
and theoretical computer science. We provide numerical experiments on matrix completion,
unsupervised clustering, and sparsest-cut SDPs. '
