Robust age estimates of red giant stars are now possible thanks to the
precise inference of their mass based on asteroseismic constraints. However,
there are cases where such age estimates can be highly precise yet very
inaccurate. An example is giants that have undergone mass loss or mass transfer
events that have sig... | http://arxiv.org/abs/2301.08761v1 |
So far, a number of wave energy converters (WEC) have been proposed to
increase efficiency and economic feasibility. Particularly, tubular WEC with
permanent magnets and coil winding packs is mostly used to convert the wave
energy. Due to the demand for high magnetic flux density in WEC, research has
been conducted on ... | http://arxiv.org/abs/2306.12946v1 |
We report results from the TESS photometric data and new high-resolution
spectra of the Algol system X Tri showing short-period pulsations. From the
echelle spectra, the radial velocities of the eclipsing pair were measured, and
the rotational rate and effective temperature of the primary star were obtained
to be $v_1$... | http://arxiv.org/abs/2302.11760v1 |
Deep learning prediction of electromagnetic software calculation results has
been a widely discussed issue in recent years. But the prediction accuracy was
still one of the challenges to be solved. In this work, we proposed that the
ResNets-10 model was used for predicting plasmonic metasurface S11 parameters.
The two-... | http://arxiv.org/abs/2308.04450v1 |
The ability to derive useful information by asking clarifying questions (ACQ)
is an important element of real life collaboration on reasoning tasks, such as
question answering (QA). Existing natural language ACQ challenges, however,
evaluate generations based on word overlap rather than the value of the
information its... | http://arxiv.org/abs/2310.11571v2 |
Concolic testing is a scalable solution for automated generation of directed
tests for validation of hardware designs. Unfortunately, concolic testing also
fails to cover complex corner cases such as hard-to-activate branches. In this
paper, we propose an incremental concolic testing technique to cover
hard-to-activate... | http://arxiv.org/abs/2302.12241v1 |
A set of orthogonal multipartite quantum states are called
(distinguishability-based) genuinely nonlocal if they are locally
indistinguishable across any bipartition of the subsystems. In this work, we
consider the problem of constructing small genuinely nonlocal sets consisting
of generalized GHZ states in multipartit... | http://arxiv.org/abs/2308.07171v3 |
We present a novel method for simulating the noisy behaviour of quantum
computers, which allows to efficiently incorporate environmental effects in the
driven evolution implementing the gates acting on the qubits. We show how to
modify the noiseless gate executed by the computer to include any Markovian
noise, hence re... | http://arxiv.org/abs/2301.04173v3 |
It is well known that inertia-free shearing flows of a viscoelastic fluid
with curved streamlines, such as the torsional flow between a rotating cone and
plate, or the flow in a Taylor-Couette geometry, can become unstable to a
three-dimensional time-dependent instability at conditions exceeding a critical
Weissenberg ... | http://arxiv.org/abs/2310.12050v2 |
Detecting lane markings in road scenes poses a challenge due to their
intricate nature, which is susceptible to unfavorable conditions. While lane
markings have strong shape priors, their visibility is easily compromised by
lighting conditions, occlusions by other vehicles or pedestrians, and fading of
colors over time... | http://arxiv.org/abs/2308.08242v4 |
We have studied a superbounce scenario in a set up of Brans-Dicke (BD)
theory. The BD parameter is considered to be time dependent and is assumed to
evolve with the Brans-Dicke scalar field. In the superbounce scenario, the
model bounces at an epoch corresponding to a Big Crunch provided the ekpyrotic
phase continues u... | http://arxiv.org/abs/2303.12168v1 |
Data-driven time-dependent magnetofrictional modelling (TMFM) of active
region magnetic fields has been proven to be a useful tool to study the corona.
The input to the model is the photospheric electric field that is inverted from
a time series of the photospheric magnetic field. Constraining the complete
electric fie... | http://arxiv.org/abs/2305.16080v1 |
Online experiments such as Randomised Controlled Trials (RCTs) or A/B-tests
are the bread and butter of modern platforms on the web. They are conducted
continuously to allow platforms to estimate the causal effect of replacing
system variant "A" with variant "B", on some metric of interest. These variants
can differ in... | http://arxiv.org/abs/2304.10900v1 |
