Energy system models require a large amount of technical and economic data,
the quality of which significantly influences the reliability of the results.
Some of the variables on the important data source ENTSO-E transparency
platform, such as transmission system operators' day-ahead load forecasts, are
known to be bia... | http://arxiv.org/abs/2302.11017v1 |
The prototypical delafossite metal PdCoO$_2$ has been the subject of intense
interest for hosting exotic transport properties. Using first-principles
transport calculations and theoretical modeling, we reveal that the high
electrical conductivity of PdCoO$_2$ at room temperature originates from the
contributions of bot... | http://arxiv.org/abs/2308.04327v1 |
Advances in Single-vehicle intelligence of automated driving have encountered
significant challenges because of limited capabilities in perception and
interaction with complex traffic environments. Cooperative Driving
Automation~(CDA) has been considered a pivotal solution to next-generation
automated driving and intel... | http://arxiv.org/abs/2301.07325v3 |
The long acquisition time has limited the accessibility of magnetic resonance
imaging (MRI) because it leads to patient discomfort and motion artifacts.
Although several MRI techniques have been proposed to reduce the acquisition
time, compressed sensing in magnetic resonance imaging (CS-MRI) enables fast
acquisition w... | http://arxiv.org/abs/2302.10309v1 |
Constrained Markov decision processes (CMDPs) model scenarios of sequential
decision making with multiple objectives that are increasingly important in
many applications. However, the model is often unknown and must be learned
online while still ensuring the constraint is met, or at least the violation is
bounded with ... | http://arxiv.org/abs/2301.11547v1 |
We propose machine learning algorithms to automatically detect and predict
clopidogrel treatment failure using longitudinal structured electronic health
records (EHR). By drawing analogies between natural language and structured
EHR, we introduce various machine learning algorithms used in natural language
processing (... | http://arxiv.org/abs/2310.08757v1 |
While quantum state tomography is notoriously hard, most states hold little
interest to practically-minded tomographers. Given that states and unitaries
appearing in Nature are of bounded gate complexity, it is natural to ask if
efficient learning becomes possible. In this work, we prove that to learn a
state generated... | http://arxiv.org/abs/2310.19882v1 |
In this paper, a new five-point targeted essentially non-oscillatory (TENO)
scheme with adaptive dissipation is proposed. With the standard TENO weighting
strategy, the cut-off parameter $C_T$ determines the nonlinear numerical
dissipation of the resultant TENO scheme. Moreover, according to the
dissipation-adaptive TE... | http://arxiv.org/abs/2303.10020v1 |
Ring-shaped superfluids with weak links provide a perfect environment for
studying persistent currents and dynamic stirring protocols. Here, we
investigate the effects of a weak-link system on dipolar supersolids. By
calculating the ground state energy at fixed angular momenta, we find that
metastable persistent curren... | http://arxiv.org/abs/2305.02972v1 |
Tuning into the bass notes of the large-scale structure requires careful
attention to geometrical effects arising from wide angles. The spherical
Fourier-Bessel (SFB) basis provides a harmonic-space coordinate system that
fully accounts for all wide-angle effects. To demonstrate the feasibility of
the SFB power spectru... | http://arxiv.org/abs/2310.17677v2 |
We develop a machine-learning method for coarse-graining condensed-phase
molecular systems using anisotropic particles. The method extends currently
available high-dimensional neural network potentials by addressing molecular
anisotropy. We demonstrate the flexibility of the method by parametrizing
single-site coarse-g... | http://arxiv.org/abs/2301.10881v1 |
The recent development of multimodal single-cell technology has made the
possibility of acquiring multiple omics data from individual cells, thereby
enabling a deeper understanding of cellular states and dynamics. Nevertheless,
the proliferation of multimodal single-cell data also introduces tremendous
challenges in mo... | http://arxiv.org/abs/2303.00233v3 |
