text: 'Holdase chaperones are essential in the mitochondrial membrane-protein biogenesis
as they stabilize preproteins and keep them in an import-competent state as they
travel through the aqueous cytosol and intermembrane space. The small TIM chaperones
of the mitochondrial intermembrane space function within a fine balance of client
promiscuity and high affinity binding, while being also able to release their
client proteins without significant energy barrier to the downstream insertases/translocases.
The tendency of the preproteins to aggregate and the dynamic nature of the preprotein—chaperone
complexes makes the preparation of these complexes challenging. Here we present
two optimized methods for complex formation of highly hydrophobic precursor proteins
and chaperones: a pull-down approach and an in-vitro translation strategy. In
the former, attaching the client protein to an affinity resin keeps the individual
client protein copies apart from each other and decreases the client self-aggregation
probability, thereby favouring complex formation. In the latter approach, a purified
chaperone, added to the cell-free protein synthesis, captures the nascent precursor
protein. The choice of method will depend on the desired client-chaperone complex
amount, or the need for specific labeling scheme.'

text: New generations of ultracold-atom experiments are continually raising the
demand for efficient solutions to optimal control problems. Here, we apply Bayesian
optimization to improve a state-preparation protocol recently implemented in an
ultracold-atom system to realize a two-particle fractional quantum Hall state.
Compared to manual ramp design, we demonstrate the superior performance of our
optimization approach in a numerical simulation – resulting in a protocol that
is 10x faster at the same fidelity, even when taking into account experimentally
realistic levels of disorder in the system. We extensively analyze and discuss
questions of robustness and the relationship between numerical simulation and
experimental realization, and how to make the best use of the surrogate model
trained during optimization. We find that numerical simulation can be expected
to substantially reduce the number of experiments that need to be performed with
even the most basic transfer learning techniques. The proposed protocol and workflow
will pave the way toward the realization of more complex many-body quantum states
in experiments.

text: Protein Data Bank (PDB) files list the relative spatial location of atoms
in a protein structure as the final output of the process of fitting and refining
to experimentally determined electron density measurements. Where experimental
evidence exists for multiple conformations, atoms are modelled in alternate locations.
Programs reading PDB files commonly ignore these alternate conformations by default
leaving users oblivious to the presence of alternate conformations in the structures
they analyze. This has led to underappreciation of their prevalence, under characterisation
of their features and limited the accessibility to this high-resolution data representing
structural ensembles. We have trawled PDB files to extract structural features
of residues with alternately located atoms. The output includes the distance between
alternate conformations and identifies the location of these segments within the
protein chain and in proximity of all other atoms within a defined radius. This
dataset should be of use in efforts to predict multiple structures from a single
sequence and support studies investigating protein flexibility and the association
with protein function.

text: 'Non-linear dynamical systems describe numerous real-world phenomena, ranging
from the weather, to financial markets and disease progression. Individual systems
may share substantial common information, for example patients’ anatomy. Lately,
deep-learning has emerged as a leading method for data-driven modeling of non-linear
dynamical systems. Yet, despite recent breakthroughs, prior works largely ignored
the existence of shared information between different systems. However, such cases
are quite common, for example, in medicine: we may wish to have a patient-specific
model for some disease, but the data collected from a single patient is usually
too small to train a deep-learning model. Hence, we must properly utilize data
gathered from other patients. Here, we explicitly consider such cases by jointly
modeling multiple systems. We show that the current single-system models consistently
fail when trying to learn simultaneously from multiple systems. We suggest a framework
for jointly approximating the Koopman operators of multiple systems, while intrinsically
exploiting common information. We demonstrate how we can adapt to a new system
using order-of-magnitude less new data and show the superiority of our model over
competing methods, in terms of both forecasting ability and statistical fidelity,
across chaotic, cardiac, and climate systems.'

compared to conventional methodologies. More precisely, we demonstrate improvements
in image quality and resolution, while reducing sensitivity to the number of recorded
frames, the mutual orthogonality of different probe modes, overlap between neighboring
probe beams and the cutoff frequency of the ptychographic microscope – properties
that are generally of paramount importance for ptychographic reconstruction algorithms.

text: In the context of in vitro fertilization (IVF), selecting embryos for transfer
is critical in determining pregnancy outcomes, with implantation as the essential
first milestone for a successful pregnancy. This study introduces the Bonna algorithm,
an advanced deep-learning framework engineered to predict embryo implantation
probabilities. The algorithm employs a sophisticated integration of machine-learning
techniques, utilizing MobileNetV2 for pixel and context embedding, a custom Pix2Pix
model for precise segmentation, and a Vision Transformer for additional depth
in embedding. MobileNetV2 was chosen for its robust feature extraction capabilities,
focusing on textures and edges. The custom Pix2Pix model is adapted for precise
segmentation of significant biological features such as the zona pellucida and
blastocyst cavity. The Vision Transformer adds a global perspective, capturing
complex patterns not apparent in local image segments. Tested on a dataset of
images of human blastocysts collected from Ukraine, Israel, and Spain, the Bonna
algorithm was rigorously validated through 10-fold cross-validation to ensure
its robustness and reliability. It demonstrates superior performance with a mean
area under the receiver operating characteristic curve (AUC) of 0.754, significantly
outperforming existing models. The study not only advances predictive accuracy
in embryo selection but also highlights the algorithm’s clinical applicability
due to reliable confidence reporting.

text: The Benjamin–Ono equation is shown to be well-posed, both on the line and
on the circle, in the Sobolev spaces H^s for s > -1/2. The proof rests on a new
gauge transformation and benefits from our introduction of a modified Lax pair
representation of the full hierarchy. As we will show, these developments yield
important additional dividends beyond well-posedness, including (i) the unification
of the diverse approaches to polynomial conservation laws; (ii) a generalization
of Gérard’s explicit formula to the full hierarchy; and (iii) new virial-type
identities covering all equations in the hierarchy.

text: 'We prove that the cubic nonlinear Schrödinger equation (both focusing and
defocusing) is globally well-posed in H^s(R) for any regularity s > −1/2. Well-posedness
has long been known for s ≥ 0, see [55], but not previously for any s < 0. The
scaling-critical value s = −1/2 is necessarily excluded here, since instantaneous
norm inflation is known to occur [11, 40, 48]. We also prove (in a parallel fashion)
well-posedness of the real- and complex-valued modified Korteweg–de Vries equations
in H^s(R) for any s > −1/2. The best regularity achieved previously was s ≥ 1/4
(see [15, 24, 33, 39]). To overcome the failure of uniform continuity of the data-to-solution
map, we employ the method of commuting flows introduced in [37]. In stark contrast
with our arguments in [37], an essential ingredient in this paper is the demonstration
of a local smoothing effect for both equations. Despite the nonperturbative nature
of the well-posedness, the gain of derivatives matches that of the underlying
linear equation. To compensate for the local nature of the smoothing estimates,
we also demonstrate tightness of orbits. The proofs of both local smoothing and
tightness rely on our discovery of a new one-parameter family of coercive microscopic
conservation laws that remain meaningful at this low regularity. '

text: Frontal ablation is responsible for a large fraction of the mass loss from
tidewater glaciers. The main contributors to frontal ablation are iceberg calving
and submarine melting, with calving often being the largest. However, submarine
melting, in addition to its direct contribution to mass loss, also promotes calving
through the changes induced in the stress field at the glacier terminus, so both
processes should be jointly analysed. Among the factors influencing submarine
melting, the formation of a buoyant plume due to the emergence of fresh subglacial
water at the glacier grounding line plays a key role. In this study we used Elmer/Ice
to develop a 3D glacier dynamics model including calving and subglacial hydrology
coupled with a line plume model to calculate the calving front position at every
time step. We applied this model to the Hansbreen–Hansbukta glacier–fjord system
in southern Spitsbergen, Svalbard, where a large set of data are available for
both the glacier and the fjord from September 2008 to March 2011. We found that
our 3D model reproduced the expected seasonal cycle of advance–retreat. Besides,
the modelled front positions were in good agreement with the observed front positions
at the central part of the calving front, with longitudinal differences, on average,
below 15 m for the period from December 2009 to March 2011. But there were regions
of the front, especially the eastern margin, that presented major differences.

text: "A Proof of Exponentiation (PoE) allows a prover to efficiently convince a
verifier that \U0001D466 = \U0001D465\r\n\U0001D452\r\nin some group of unknown
order. PoEs\r\nare the basis for practical constructions of Verifiable Delay Functions
(VDFs), which, in turn, are important for various higher-level\r\nprotocols in
distributed computing. In applications such as distributed consensus, many PoEs
are generated regularly, motivating\r\nprotocols for secure aggregation of batches
of statements into a\r\nfew statements to improve the efficiency for both parties.
Rotem\r\n(TCC 2021) recently presented two such generic batch PoEs.\r\nIn this
work, we introduce two batch PoEs that outperform\r\nboth proposals of Rotem and
we evaluate their practicality. First,\r\nwe show that the two batch PoEs of Rotem
can be combined to\r\nimprove the overall efficiency by at least a factor of two.
Second, we\r\nrevisit the work of Bellare, Garay, and Rabin (EUROCRYPT 1998)\r\non
batch verification of digital signatures and show that, under the\r\nlow order
assumption, their bucket test can be securely adapted to\r\nthe setting of groups
of unknown order. The resulting batch PoE\r\nquickly outperforms the state of
the art in the expected number of\r\ngroup multiplications with the growing number
of instances, and it\r\ndecreases the cost of batching by an order of magnitude
already for\r\nhundreds of thousands of instances. Importantly, it is the first
batch\r\nPoE that significantly decreases both the proof size and complexity\r\nof
verification. Our experimental evaluations show that even a nonoptimized implementation
achieves such improvements, which\r\nwould match the demands of real-life systems
requiring large-scale\r\nPoE processing.\r\nFinally, even though our proof techniques
are conceptually similar to Rotem, we give an improved analysis of the application
of the\r\nlow order assumption towards secure batching of PoE instances,\r\nresulting
in a tight reduction, which is important when setting the\r\nsecurity parameter
in practice."

text: 'The inertia bound and ratio bound (also known as the Cvetković bound and
Hoffman bound) are two fundamental inequalities in spectral graph theory, giving
upper bounds on the independence number a(G) of a graph G in terms of spectral
information about a weighted adjacency matrix of G. For both inequalities, given
a graph G, one needs to make a judicious choice of weighted adjacency matrix to
obtain as strong a bound as possible. While there is a well‐established theory
surrounding the ratio bound, the inertia bound is much more mysterious, and its
limits are rather unclear. In fact, only recently did Sinkovic find the first
example of a graph for which the inertia bound is not tight (for any weighted
adjacency matrix), answering a longstanding question of Godsil. We show that the
inertia bound can be extremely far from tight, and in fact can significantly underperform
the ratio bound: for example, one of our results is that for infinitely many n,
there is an n‐vertex graph for which even the unweighted ratio bound can prove
a(G)<4n^3/4, but the inertia bound is always at least n/4. In particular, these
results address questions of Rooney, Sinkovic, and Wocjan–Elphick–Abiad.'

text: "Burr and Erd˝os in 1975 conjectured, and Chv´atal, R¨odl, Szemer´edi and\r\nTrotter
later proved, that the Ramsey number of any bounded degree\r\ngraph is linear
in the number of vertices. In this paper, we disprove\r\nthe natural directed
analogue of the Burr–Erd˝os conjecture, answering a\r\nquestion of Buci´c, Letzter,
and Sudakov. If H is an acyclic digraph, the\r\noriented Ramsey number of H, denoted
−→r1(H), is the least N such that\r\nevery tournament on N vertices contains a
copy of H. We show that for\r\nany Δ ≥ 2 and any sufficiently large n, there exists
an acyclic digraph H\r\nwith n vertices and maximum degree Δ such that\r\n−→r1(H)
≥ nΩ(Δ2/3/ log5/3 Δ).\r\nThis proves that −→r1(H) is not always linear in the
number of vertices for\r\nbounded-degree H. On the other hand, we show that −→r1(H)
is nearly linear\r\nin the number of vertices for typical bounded-degree acyclic
digraphs H,\r\nand obtain linear or nearly linear bounds for several natural families
of\r\nbounded-degree acyclic digraphs.\r\nFor multiple colors, we prove a quasi-polynomial
upper bound −→rk(H)=\r\n2(log n)Ok(1) for all bounded-degree acyclic digraphs
H on n vertices, where −→rk(H) is the least N such that every k-edge-colored tournament
on N\r\nvertices contains a monochromatic copy of H. For k ≥ 2 and n ≥ 4, we\r\nexhibit
an acyclic digraph H with n vertices and maximum degree 3 such\r\nthat −→rk(H)
≥ nΩ(log n/ log log n), showing that these Ramsey numbers can\r\ngrow faster than
any polynomial in the number of vertices."

text: Given a graph , its Ramsey number is the minimum so that every two‐coloring
of contains a monochromatic copy of . It was conjectured by Conlon, Fox, and
Sudakov that if one deletes a single vertex from , the Ramsey number can change
by at most a constant factor. We disprove this conjecture, exhibiting an infinite
family of graphs such that deleting a single vertex from each decreases the Ramsey
number by a super‐constant factor. One consequence of this result is the following.
There exists a family of graphs so that in any Ramsey coloring for (i.e., a
coloring of a clique on vertices with no monochromatic copy of ), one of the
color classes has density .

text: The curvature of elongated microscopic building blocks plays a crucial role
on their self-assembly into orientationally ordered phases. While rod-like molecules
form a handful of liquid crystal (LC) phases, curved or banana-shaped molecules
show more than fifty phases, with fascinating physical properties, such as chirality
or polarity. Despite the fundamental and technological importance of these so-called
‘banana-shaped liquid crystals’, little is known about their microscopic details
at the single-molecule level. Curved colloidal liquid crystals—liquid crystals
formed by curved colloidal rods—are excellent model systems to optically resolve
the structure and dynamics of curved building blocks within these condensed phases.
Recent advances in the synthesis of curved rod-like particles have unlocked the
potential for studying—at the single-particle level—the intimate relationship
between shape and phase symmetry, and even confirmed the stability of elusive
LC phases. Further developments in this nascent field promise exciting findings,
such as the first observation of the colloidal twist-bend nematic phase or the
fabrication of functional materials with curvature-dependent properties. In this
Report on Progress, we will highlight recent advances in the synthesis and assembly
of curved colloidal liquid crystals and discuss the upcoming challenges and opportunities
of this field.
