text: At least 5% of questions submitted to search engines ask about cause-effect
relationships in some way. To support the development of tailored approaches that
can answer such questions, we construct Webis-CausalQA-22, a benchmark corpus
of 1.1 million causal questions with answers. We distinguish different types of
causal questions using a novel typology derived from a data-driven, manual analysis
of questions from ten large question answering (QA) datasets. Using high-precision
lexical rules, we extract causal questions of each type from these datasets to
create our corpus. As an initial baseline, the state-of-the-art QA model UnifiedQA
achieves a ROUGE-L F1 score of 0.48 on our new benchmark.

text: "Electronic structure calculations have been instrumental in providing many\r\nimportant
insights into a range of physical and chemical properties of various\r\nmolecular
and solid-state systems. Their importance to various fields,\r\nincluding materials
science, chemical sciences, computational chemistry and\r\ndevice physics, is
underscored by the large fraction of available public\r\nsupercomputing resources
devoted to these calculations. As we enter the\r\nexascale era, exciting new opportunities
to increase simulation numbers, sizes,\r\nand accuracies present themselves. In
order to realize these promises, the\r\ncommunity of electronic structure software
developers will however first have\r\nto tackle a number of challenges pertaining
to the efficient use of new\r\narchitectures that will rely heavily on massive
parallelism and hardware\r\naccelerators. This roadmap provides a broad overview
of the state-of-the-art in\r\nelectronic structure calculations and of the various
new directions being\r\npursued by the community. It covers 14 electronic structure
codes, presenting\r\ntheir current status, their development priorities over the
next five years,\r\nand their plans towards tackling the challenges and leveraging
the\r\nopportunities presented by the advent of exascale computing."

text: "The CP2K program package, which can be considered as the swiss army knife
of\r\natomistic simulations, is presented with a special emphasis on ab-initio\r\nmolecular
dynamics using the second-generation Car-Parrinello method. After\r\noutlining
current and near-term development efforts with regards to massively\r\nparallel
low-scaling post-Hartree-Fock and eigenvalue solvers, novel approaches\r\non how
we plan to take full advantage of future low-precision hardware\r\narchitectures
are introduced. Our focus here is on combining our submatrix\r\nmethod with the
approximate computing paradigm to address the immanent exascale\r\nera."

text: A parallel hybrid quantum-classical algorithm for the solution of the quantum-chemical
ground-state energy problem on gate-based quantum computers is presented. This
approach is based on the reduced density-matrix functional theory (RDMFT) formulation
of the electronic structure problem. For that purpose, the density-matrix functional
of the full system is decomposed into an indirectly coupled sum of density-matrix
functionals for all its subsystems using the adaptive cluster approximation to
RDMFT. The approximations involved in the decomposition and the adaptive cluster
approximation itself can be systematically converged to the exact result. The
solutions for the density-matrix functionals of the effective subsystems involves
a constrained minimization over many-particle states that are approximated by
parametrized trial states on the quantum computer similarly to the variational
quantum eigensolver. The independence of the density-matrix functionals of the
effective subsystems introduces a new level of parallelization and allows for
the computational treatment of much larger molecules on a quantum computer with
a given qubit count. In addition, for the proposed algorithm techniques are presented
to reduce the qubit count, the number of quantum programs, as well as its depth.
The evaluation of a density-matrix functional as the essential part of our approach
is demonstrated for Hubbard-like systems on IBM quantum computers based on superconducting
transmon qubits.

text: "Electronic structure calculations have been instrumental in providing many\r\nimportant
insights into a range of physical and chemical properties of various\r\nmolecular
and solid-state systems. Their importance to various fields,\r\nincluding materials
science, chemical sciences, computational chemistry and\r\ndevice physics, is
underscored by the large fraction of available public\r\nsupercomputing resources
devoted to these calculations. As we enter the\r\nexascale era, exciting new opportunities
to increase simulation numbers, sizes,\r\nand accuracies present themselves. In
order to realize these promises, the\r\ncommunity of electronic structure software
developers will however first have\r\nto tackle a number of challenges pertaining
to the efficient use of new\r\narchitectures that will rely heavily on massive
parallelism and hardware\r\naccelerators. This roadmap provides a broad overview
of the state-of-the-art in\r\nelectronic structure calculations and of the various
new directions being\r\npursued by the community. It covers 14 electronic structure
codes, presenting\r\ntheir current status, their development priorities over the
next five years,\r\nand their plans towards tackling the challenges and leveraging
the\r\nopportunities presented by the advent of exascale computing."

text: 'In this report we present our system for the Detection and Classification
of Acoustic Scenes and Events (DCASE) 2022 Challenge Task 4: Sound Event Detection
in Domestic Environments 1 . As in previous editions of the Challenge, we use
forward-backward convolutional recurrent neural networks (FBCRNNs) [1, 2] for
weakly labeled and semi-supervised sound event detection (SED) and eventually
generate strong pseudo labels for weakly labeled and unlabeled data. Then, (tag-conditioned)
bidirectional CRNNs (Bi-CRNNs) [1, 2] are trained in a strongly supervised manner
as our final SED models. In each of the training stages we use multiple iterations
of self-training. Compared to previous editions, we improved our system performance
by 1) some tweaks regarding data augmentation, pseudo labeling and inference 2)
using weakly labeled AudioSet data [3] for pretraining larger networks and 3)
augmenting the DESED data [4] with strongly labeled AudioSet data [5] for finetuning
of the networks. Source code is publicly available at https://github.com/fgnt/pb_sed.'

text: In this publication a novel method for far-field prediction from magnetic
Huygens box data based on the boundary element method (BEM) is presented. Two
examples are considered for the validation of this method. The first example represents
an electric dipole so that the obtained calculations can be compared to an analytical
solution. As a second example, a printed circuit board is considered and the calculated
far-field is compared to a fullwave simulation. In both cases, the calculations
for different field integral equations are under comparison, and the results indicate
that the presented method performs very well with a combined field integral equation,
for the specified problem, when only magnetic Huygens box data is given.

text: "Impressive progress in neural network-based single-channel speech source\r\nseparation
has been made in recent years. But those improvements have been\r\nmostly reported
on anechoic data, a situation that is hardly met in practice.\r\nTaking the SepFormer
as a starting point, which achieves state-of-the-art\r\nperformance on anechoic
mixtures, we gradually modify it to optimize its\r\nperformance on reverberant
mixtures. Although this leads to a word error rate\r\nimprovement by 7 percentage
points compared to the standard SepFormer\r\nimplementation, the system ends up
with only marginally better performance than\r\na PIT-BLSTM separation system,
that is optimized with rather straightforward\r\nmeans. This is surprising and
at the same time sobering, challenging the\r\npractical usefulness of many improvements
reported in recent years for monaural\r\nsource separation on nonreverberant data."

abstract:
- lang: eng
text: 'Hole polarons and defect-bound exciton polarons in lithium niobate are investigated
by means of density-functional theory, where the localization of the holes is
achieved by applying the +U approach to the oxygen 2p orbitals. We find three
principal configurations of hole polarons: (i) self-trapped holes localized at
displaced regular oxygen atoms and (ii) two other configurations bound to a lithium
vacancy either at a threefold coordinated oxygen atom above or at a two-fold coordinated
oxygen atom below the defect. The latter is the most stable and is in excellent
quantitative agreement with measured g factors from electron paramagnetic resonance.
Due to the absence of mid-gap states, none of these hole polarons can explain
the broad optical absorption centered between 2.5 and 2.8 eV that is observed
in transient absorption spectroscopy, but such states appear if a free electron
polaron is trapped at the same lithium vacancy as the bound hole polaron, resulting
in an exciton polaron. The dielectric function calculated by solving the Bethe–Salpeter
equation indeed yields an optical peak at 2.6 eV in agreement with the two-photon
experiments. The coexistence of hole and exciton polarons, which are simultaneously
created in optical excitations, thus satisfactorily explains the reported experimental
data.'
