text: We consider a local Cahn–Hilliard‐type model for tumor growth as well as a
nonlocal model where, compared to the local system, the Laplacian in the equation
for the chemical potential is replaced by a nonlocal operator. The latter is defined
as a convolution integral with suitable kernels parametrized by a small parameter.
For sufficiently smooth bounded domains in three dimensions, we prove convergence
of weak solutions of the nonlocal model toward strong solutions of the local model
together with convergence rates with respect to the small parameter. The proof
is done via a Gronwall‐type argument and a convergence result with rates for the
nonlocal integral operator toward the Laplacian due to Abels and Hurm.

text: 'We present the Red Unknowns: Bright Infrared Extragalactic Survey (RUBIES)
providing JWST/NIRSpec spectroscopy of red sources selected across ∼150 arcmin2
from public JWST/NIRCam imaging in the UDS and EGS fields. The novel observing
strategy of RUBIES offers a well-quantified selection function. The survey has
been optimised to reach high (>70%) spectroscopic completeness for bright and
red (F150W−F444W>2) sources that are very rare. To place these rare sources in
context, we simultaneously observed a reference sample of the 23 using only the G395M
disperser. The RUBIES data reveal a highly diverse population of red sources that
span a broad redshift range (zspec∼1−9), with photometric redshift scatter and
an outlier fraction that are three times higher than for similarly bright sources
that are less red. This diversity is not apparent from the photometric spectral
energy distributions (SEDs). Only spectroscopy reveals that the SEDs encompass
a mixture of galaxies with dust-obscured star formation, extreme line emission,
a lack of star formation indicating early quenching, and luminous active galactic
nuclei. As a first demonstration of our broader selection function we compared
the stellar masses and rest-frame U−V colours of the red sources and our reference
sample. We find that the red sources are typically more massive (M*∼1010−11.5 M⊙)
across all redshifts. However, we also find that the most massive systems span
a wide range in U−V colour. We describe our data reduction procedure and data
quality, and we publicly release the reduced RUBIES data and vetted spectroscopic
redshifts of the first half of the survey through the DAWN JWST Archive.'

text: 'We consider a family of totally asymmetric simple exclusion processes (TASEPs),
consisting of particles on a lattice that require binding by a “token” in various
physical configurations to advance over the lattice. Using a combination of theory
and simulations, we address the following questions: (i) How does token binding
kinetics affect the current-density relation on the lattice? (ii) How does this
current-density relation depend on the scarcity of tokens? (iii) How do tokens
propagate the effects of the locally imposed disorder (such as a slow site) over
the entire lattice? (iv) How does a shared pool of tokens couple concurrent TASEPs
running on multiple lattices? and (v) How do our results translate to TASEPs with
open boundaries that exchange particles with the reservoir? Since real particle
motion (including in biological systems that inspired the standard TASEP model,
e.g., protein synthesis or movement of molecular motors) is often catalyzed, regulated,
actuated, or otherwise mediated, the token-driven TASEP dynamics analyzed in this
paper should allow for a better understanding of real systems and enable a closer
match between TASEP theory and experimental observations.'

text: Confinement is a prominent phenomenon in condensed matter and high-energy
physics that has recently become the focus of quantum-simulation experiments of
lattice gauge theories (LGTs). As such, a theoretical understanding of the effect
of confinement on LGT dynamics is not only of fundamental importance, but can
lend itself to upcoming experiments. Here, we show how confinement in a Z2 LGT
can be locally avoided by proximity to a resonance between the fermion mass and
the electric field strength. Furthermore, we show that this local deconfinement
can become global for certain initial conditions, where information transport
occurs over the entire chain. In addition, we show how this can lead to strong
quantum many-body scarring starting in different initial states. Our findings
provide deeper insights into the nature of confinement in Z2 LGTs and can be tested
on current and near-term quantum devices.

text: Status epilepticus (SE), seizures lasting beyond five minutes, is a medical
emergency commonly treated with benzodiazepines which enhance GABAA receptor (GABAAR)
conductance. Despite widespread use, benzodiazepines fail in over one-third of
patients, potentially due to seizure-induced disruption of neuronal chloride (Cl−)
homeostasis. Understanding these changes at a network level is crucial for improving
clinical translation. Here, we address this using a large-scale spiking neural
network model incorporating Cl− dynamics, informed by clinical EEG and experimental
slice recordings. Our simulations confirm that the GABAAR reversal potential (EGABA)
dictates the pro- or anti-seizure effect of GABAAR conductance modulation, with
high EGABA rendering benzodiazepines ineffective or excitatory. We show SE-like
activity and EGABA depend non-linearly on Cl− extrusion efficacy and GABAAR conductance.
Critically, cell-type specific manipulations reveal that pyramidal cell, not interneuron,
Cl− extrusion predominantly determines the severity of SE activity and the response
to simulated benzodiazepines. Leveraging these mechanistic insights, we develop
a predictive framework mapping network states to Cl− extrusion capacity and GABAergic
load, yielding a proposed decision-making strategy to guide therapeutic interventions
based on initial treatment response. This work identifies pyramidal cell Cl− handling
as a key therapeutic target and demonstrates the utility of biophysically detailed
network models for optimising SE treatment protocols.

text: Super-resolution microscopy often entails long acquisition times of minutes
to hours. Since drifts during the acquisition adversely affect data quality, active
sample stabilization is commonly used for some of these techniques to reach their
full potential. Although drifts in the lateral plane can often be corrected after
acquisition, this is not always possible or may come with drawbacks. Therefore,
it is appealing to stabilize sample position in three dimensions (3D) during acquisition.
Various schemes for active sample stabilization have been demonstrated previously,
with some reaching sub-nanometer stability in 3D. Here, we present a scheme for
active drift correction that delivers the nanometer-scale 3D stability demanded
by state-of-the-art super-resolution techniques and is straightforward to implement
compared to previous schemes capable of reaching this level of stabilization precision.
Using a refined algorithm that can handle various types of reference structure,
without sparse signal peaks being mandatory, we stabilized sample position to
∼1 nm in 3D using objective lenses both with high and low numerical aperture.
Our implementation requires only the addition of a simple widefield imaging path
and we provide an open-source control software with graphical user interface to
facilitate easy adoption of the module. Finally, we demonstrate how this has the
potential to enhance data collection for diffraction-limited and super-resolution
imaging techniques using single-molecule localization microscopy and cryo-confocal
imaging as showcases.

text: "Motivation: Boolean networks are popular dynamical models of cellular processes
in systems biology. Their attractors model phenotypes that arise from the interplay
of key regulatory subcircuits. A succession diagram (SD) describes this interplay
in a discrete analog of Waddington’s epigenetic attractor landscape that allows
for fast identification of attractors and attractor control strategies. Efficient
computational tools for studying SDs are essential for the understanding of Boolean
attractor landscapes and connecting them to their biological functions.\r\nResults:
We present a new approach to SD construction for asynchronously updated Boolean
networks, implemented in the biologist’s Boolean attractor landscape mapper, biobalm.
We compare biobalm to similar tools and find a substantial performance increase
in SD construction, attractor identification, and attractor control. We perform
the most comprehensive comparative analysis to date of the SD structure in experimentally-validated
Boolean models of cell processes and random ensembles. We find that random models
(including critical Kauffman networks) have relatively small SDs, indicating simple
decision structures. In contrast, nonrandom models from the literature are enriched
in extremely large SDs, indicating an abundance of decision points and suggesting
the presence of complex Waddington landscapes in nature.\r\nAvailability and implementation:
The tool biobalm is available online at https://github.com/jcrozum/biobalm. Further
data, scripts for testing, analysis, and figure generation are available online
at https://github.com/jcrozum/biobalm-analysis and in the reproducibility artefact

text: Stars stripped of their hydrogen-rich envelopes through binary interaction
are thought to be responsible for both hydrogen-poor supernovae and the hard ionizing
radiation observed in low-Z galaxies. A population of these stars was recently
observed for the first time, but their prevalence remains unknown. In preparation
for such measurements, we estimate the mass distribution of hot, stripped stars
using a population synthesis code that interpolates over detailed single and binary
stellar evolution tracks. We predict that for a constant star formation rate of
1 M⊙/yr and regardless of metallicity, a scalable model population contains ∼30
000 stripped stars with mass Mstrip > 1 M⊙ and ∼4000 stripped stars that are sufficiently
massive to explode (Mstrip > 2.6 M⊙). Below Mstrip = 5 M⊙, the distribution is
metallicity-independent and can be described by a power law with the exponent
α ∼ −2. At higher masses and lower metallicity (Z ≲ 0.002), the mass distribution
exhibits a drop. This originates from the prediction, frequently seen in evolutionary
models, that massive low-metallicity stars do not expand substantially until central
helium burning or later and therefore cannot form long-lived stripped stars. With
weaker line-driven winds at low metallicity, this suggests that neither binary
interaction nor wind mass loss can efficiently strip massive stars at low metallicity.
As a result, a “helium-star desert” emerges around Mstrip = 15 M⊙ at Z = 0.002,
covering an increasingly large mass range with decreasing metallicity. We note
that these high-mass stars are those that potentially boost a galaxy’s He+-ionizing
radiation and that participate in the formation of merging black holes. This “helium-star
desert” therefore merits further study.

text: In an n×n array filled with symbols, a transversal is a collection of entries
with distinct rows, columns and symbols. In this note we show that if no symbol
appears more than βn times, the array contains a transversal of size (1−β/4−o(1))n
. In particular, if the array is filled with n symbols, each appearing n times
(an equi- n square), we get transversals of size (3/4−o(1))n. Moreover, our
proof gives a deterministic algorithm with polynomial running time, that finds
these transversals.

text: Eigenstates of quantum many-body systems are often used to define phases of
matter in and out of equilibrium; however, experimentally accessing highly excited
eigenstates is a challenging task, calling for alternative strategies to dynamically
probe nonequilibrium phases. In this work, we characterize the dynamical properties
of a disordered spin chain, focusing on the spin-glass regime. Using tensor-network
simulations, we observe oscillatory behavior of local expectation values and bipartite
entanglement entropy. We explain these oscillations deep in the many-body localized
spin-glass regime via a simple theoretical model. From perturbation theory, we
predict the timescales up to which our analytical description is valid and confirm
it with numerical simulations. Finally, we study the correlation length dynamics,
which, after a long-time plateau, resume growing in line with renormalization
group (RG) expectations. Our work suggests that RG predictions can be quantitatively
tested against numerical simulations and experiments, potentially enabling microscopic
descriptions of dynamical phases in large systems.

text: The snow and glaciers of the Peruvian Andes provide vital water supplies in
a region facing water scarcity and substantial glacier change. However, there
remains a lack of understanding of snow processes and quantification of the contribution
of melt to runoff. Here we apply a distributed glacio-hydrological model over
the Rio Santa basin to disentangle the role of the cryosphere in the Andean water
cycle. Only at the highest elevations (>5000 m a.s.l.) is the snow cover continuous;
at lower elevations, the snowpack is thin and ephemeral, with rapid cycles of
snowfall and melt. Due to the large catchment area affected by ephemeral snow,
its contribution to catchment inputs is substantial (23% and 38% in the wet and
dry season, respectively). Ice melt is crucial in the mid-dry season (up to 44%
of inputs). Our results improve estimates of water fluxes and call for further
process-based modelling across the Andes.

text: "We report the discovery of two new magnetic cataclysmic variables with brown
dwarf companions and long orbital periods (P_{\\rm orb}=95\\pm1 and 104\\pm2 min).
This discovery increases the sample of candidate magnetic period bouncers with
confirmed sub-stellar donors from four to six. We also find their X-ray luminosity
from archival XMM–Newton observations to be in the range L_{\\rm X}\\approx10^{28}-10^{29}
\\mathrm{erg\\,s^{-1}} in the 0.25–10 keV band. This low luminosity is comparable
with the other candidates, and at least an order of magnitude lower than the X-ray
luminosities typically measured in cataclysmic variables. The X-ray fluxes imply
mass transfer rates that are much lower than predicted by evolutionary models,
even if some of the discrepancy is due to the accretion energy being emitted in
other bands, such as via cyclotron emission at infrared wavelengths. Although
it is possible that some or all of these systems formed directly as binaries containing
a brown dwarf, it is likely that the donor used to be a low-mass star and that
the systems followed the evolutionary track for cataclysmic variables, evolving
past the period bounce. The donor in long period systems is expected to be a low-mass,
cold brown dwarf. This hypothesis is supported by near-infrared photometric observations
that constrain the donors in the two systems to be brown dwarfs cooler than \r\n1100 K
(spectral types T5 or later), most likely losing mass via Roche Lobe overflow
or winds. The serendipitous discovery of two magnetic period bouncers in the small
footprint of the XMM–Newton catalogue implies a large space density of these type
of systems, possibly compatible with the prediction of 40–70 per cent of magnetic
cataclysmic variables to be period bouncers."

text: "Context. The blue supergiant (BSG) domain contains a large variety of stars
whose past and future evolutionary paths are still highly uncertain. Since binary
interaction plays a crucial role in the fate of massive stars, investigating the
multiplicity among BSGs helps shed light on the fate of such objects.\r\nAims.
We aim to estimate the binary fraction of a large sample of BSGs in the Small
Magellanic Cloud (SMC) within the Binarity at LOw Metallicity (BLOeM) survey.
In total, we selected 262 targets with spectral types B0-B3 and luminosity classes
I-II.\r\n\r\nMethods. This work is based on spectroscopic data collected by the
FLAMES instrument, mounted on the Very Large Telescope, which gathered nine epochs
over three months. Our spectroscopic analysis for each target includes the individual
and peak-to-peak radial velocity measurements, an investigation of the line profile
variability, and a periodogram analysis to search for possible short- and long-period
binaries.\r\n\r\nResults. By applying a 20 km s−1 threshold on the peak-to-peak
radial velocities above which we would consider the star to be binary, the resulting
observed spectroscopic binary fraction for our BSG sample is 23 ± 3%. An independent
analysis of line profile variability reveals 11 (plus 5 candidates) double-lined
spectroscopic binaries and 32 (plus 41 candidates) single-lined spectroscopic
binaries. Based on these results, we estimated the overall observed binary fraction
in this sample to be 34 ± 3%, which is close to the computed intrinsic binary
fraction of 40 ± 4%. In addition, we derived reliable orbital periods for 41 spectroscopic
binaries and potential binary candidates, among which there are 17 eclipsing binaries,
including 20 SB1 and SB2 systems with periods of less than 10 days. We reported
a significant drop in the binary fraction of BSGs with spectral types later than
B2 and effective temperatures less than 18 kK, which could indicate the end of
the main sequence phase in this temperature regime. We found no metallicity dependence
in the binary fraction of BSGs, compared to existing spectroscopic surveys of
the Galaxy and Large Magellanic Cloud."

text: Given the uncertain evolutionary status of blue supergiant stars, their multiplicity
properties hold vital clues to better understand their origin and evolution. As
part of The Binarity at LOw Metallicity (BLOeM) campaign in the Small Magellanic
Cloud, we present a multi-epoch spectroscopic survey of 128 supergiant stars of
spectral type B5–F5, which roughly correspond to initial masses in the 6–30 M⊙
range. The observed binary fraction for the B5–9 supergiants is 25 ± 6% (10 ±
4%) and 5 ± 2% (0%) for the A–F stars, which were found using a radial-velocity
(RV) variability threshold of 5 km s−1 (10 km s−1) as a criterion for binarity.
Accounting for observational biases, we find an intrinsic multiplicity fraction
of less than 18% for the B5–9 stars and 8−7+9% for the AF stars, for the orbital
periods up to 103.5 days and mass ratios (q) in the 0.1 < q < 1 range. The large
stellar radii of these supergiant stars prevent short orbital periods, but we
demonstrate that this effect alone cannot explain our results. We assessed the
spectra and RV time series of the detected binary systems and find that only a
small fraction display convincing solutions. We conclude that the multiplicity
fractions are compromised by intrinsic stellar variability, such that the true
multiplicity fraction may be significantly smaller. Our main conclusions from
comparing the multiplicity properties of the B5–9- and AF-type supergiants to
that of their less evolved counterparts is that such stars cannot be explained
by a direct evolution from the main sequence. Furthermore, by comparing their
multiplicity properties to red supergiant stars, we conclude that the AF supergiant
stars are neither progenitors nor descendants of red supergiants.

text: 'Social dilemmas are collective-action problems where individual interests
are at odds with group interests. Such dilemmas occur frequently at all scales
of human interactions. When dealing with collective-action problems, people often
act reciprocally. They adjust their behavior to match the previous behavior of
the recipient. The literature distinguishes two kinds of reciprocity. According
to direct reciprocity, individuals react to their immediate experiences with the
recipient. They are more likely to cooperate if the recipient previously cooperated
with them. According to indirect reciprocity, individuals react to the recipient’s
general behavior, irrespectively of whether or not they benefited directly. In
practice, the two kinds of reciprocity are often intertwined; people typically
base their decisions on both direct experiences and indirect observations. Yet
only recently have researchers begun to explore how the two kinds of reciprocity
interact. So far, this research only addresses a single type of social dilemma,
the donation game, where the effects of individual behaviors are independent.
Instead, here we allow for all pairwise social dilemmas. By applying novel techniques
to generalize the theory of zero-determinant strategies, we establish an important
proof of principle: In all social dilemmas, socially optimal outcomes can be sustained
as an equilibrium, using either direct or indirect reciprocity, or arbitrary mixtures
thereof. These results neither require games to be repeated infinitely often,
nor that individual opinions are synchronized. In this way, we considerably generalize
the scope of models of reciprocity, and we build further bridges between the literatures
on direct and indirect reciprocity.'

text: "Context. Rapidly rotating classical OBe stars have been proposed as the products
of binary interactions, and the fraction of Be stars with compact companions implies
that at least some are. However, to constrain the interaction physics spinning
up the OBe stars, a large sample of homogeneously analyzed OBe stars with well-determined
binary characteristics and orbital parameters are required.\r\n\r\nAims. We investigated
the multiplicity properties of a sample of 18 Oe, 62 Be, and two Of?p stars observed
within the BLOeM survey in the Small Magellanic Cloud. We analyzed the first nine
epochs of spectroscopic observations obtained over approximately three months
in 2023.\r\n\r\nMethods. Radial velocities (RVs) of all stars were measured using
cross-correlation based on different sets of absorption and emission lines. Applying
commonly used binarity criteria, we classified objects as binaries, binary candidates,
and apparently single (RV stable) objects. We further inspected the spectra for
double-lined spectroscopic binaries and cross-matched with catalogs of X-ray sources
and photometric binaries.\r\n\r\nResults. We classify 14 OBe stars as binaries,
and an additional 11 as binary candidates. The two Of?p stars are apparently single.
We find two more objects that are most likely currently interacting binaries.
Without those, the observed binary fraction for the remaining OBe sample of 78
stars is fobs+candOBe = 0.18 ± 0.04 (fobs+candOBe = 0.32±0.05 including candidates).
This binary fraction is less than half of that measured for OB stars in BLOeM.
Combined with the lower fraction of SB2s, this suggests that OBe stars do indeed
have fundamentally different present-day binary properties than OB stars. We find
no evidence for OBe binaries with massive compact companions, in contrast to expectations
from binary population synthesis.\r\n\r\nConclusions. Our results support the
binary scenario as an important formation channel for OBe stars, as post-interaction
binaries may have been disrupted or the stripped companions of OBe stars are harder
to detect. Further observations are required to characterize the detected binaries,
their orbital parameters, and the nature of their companions."

text: "Context. The recently launched James Webb Space Telescope (JWST) is opening
new observing windows on the distant Universe. Among JWST’s instruments, the Mid
Infrared Instrument (MIRI) offers the unique capability of imaging observations
at wavelengths of λ > 5 μm. This enables unique access to the rest frame near-infrared
(NIR, λ ≥ 1 μm) emission from galaxies at redshifts of z > 4 and the visual (λ ≳ 5000
Å) rest frame for z > 9. We report here on the guaranteed time observations (GTO),
from the MIRI European Consortium, of the Hubble Ultra Deep Field (HUDF), forming
the MIRI Deep Imaging Survey (MIDIS), consisting of an on source integration time
of ∼41 hours in the MIRI/F560W (5.6 μm) filter. The F560W filter was selected
since it would produce the deepest data in terms of AB magnitudes in a given time.
To our knowledge, this constitutes the longest single filter exposure obtained
with JWST of an extragalactic field as of yet.\r\nAims. The HUDF is one of the
most observed extragalactic fields, with extensive multi-wavelength coverage,
where (before JWST) galaxies up to z ∼ 7 have been confirmed, and at z > 10 suggested,
from HST photometry. We aim to characterise the galaxy population in HUDF at 5.6
μm, enabling studies such as: the rest frame NIR morphologies for galaxies at
z ≲ 4.6, probing mature stellar populations and emission lines in z > 6 sources,
intrinsically red and dusty galaxies, and active galactic nuclei (AGNs) and their
host galaxies at intermediate redshifts.\r\n\r\nMethods. We reduced the MIRI data
using the official JWST pipeline, augmented by in-house custom scripts. We measured
the noise characteristics of the resulting image. Galaxy photometry was obtained,
and photometric redshifts were estimated for sources with available multi-wavelength
photometry (and compared to spectroscopic redshifts when available).\r\n\r\nResults.
Over the deepest part of our image, the 5σ point source limit is 28.65 mag AB
(12.6 nJy), ∼0.35 mag better than predicted by the JWST exposure time calculator.
We find ∼2500 sources, the overwhelming majority of which are distant galaxies,
but we note that spurious sources likely remain at faint magnitudes due to imperfect
cosmic ray rejection in the JWST pipeline. More than 500 galaxies with available
spectroscopic redshifts, up to z ≈ 11, have been identified, the majority of which
are at z < 6. More than 1000 galaxies have reliable photometric redshift estimates,
of which ∼25 are at 6 < z < 12. The point spread function in the F560W filter
has a full width at half maximum (FWHM) of ≈0.2″ (corresponding to 1.4 kpc at
z = 4), allowing the NIR rest frame morphologies and stellar mass distributions
to be resolved for z < 4.5. Moreover, > 100 objects with very red NIRCam vs MIRI
(3.6–5.6 μm > 1 mag) colours have been found, suggestive of dusty or old stellar
populations at high redshifts.\r\n\r\nConclusions. We conclude that MIDIS surpasses
preflight expectations and that deep MIRI imaging has great potential to characterise
the galaxy population from cosmic noon to dawn."

text: The Ca2+-release-activated Ca2+ (CRAC) channel Orai1 is activated by interaction
with the Ca2+ sensor Stromal Interaction Molecule 1 (STIM1). Owing to the lack
of structurally resolved Orai1/STIM1 complexes, the impact of their coupling on
individual Orai1 transmembrane domain (TM) movements is unclear. This study investigates
STIM1-independent and STIM1-dependent Orai1-TM dynamics using photocrosslinking
unnatural amino acids (UAAs) at each individual TM position. We primarily identify
CRAC-channel-like currents directly after UAA incorporation or additional UV-light
irradiation at TM3 sites that interface with non-pore-lining TMs. Using UAAs combined
with conventional site-directed mutagenesis and molecular dynamics simulations,
we discover that pore opening involves a widening of interfaces formed by TM3
with non-pore-lining TMs. Orai1 mutants with a UAA in TM3 exhibit weaker STIM1-induced
activation after UV exposure, possibly caused by a restricted widening of non-pore-lining
TM interfaces. We demonstrate that photocrosslinking UAAs are excellent tools
for improving our understanding of key determinants and ion channel dynamics modulating
pore opening.

text: Prussian blue (PB) and Prussian blue analogues (PBAs) are a class of porous
materials composed of transition metal cations, cyanide ligands, and alkali metal
cations. Their ability to intercalate and deintercalate ions within their framework
pores, coupled with the adaptability of their crystal structure to electrochemical
changes, underpins their success in battery applications. PBAs with Fe or Co as
the active site exhibit high redox potentials (vs SHE) and have been extensively
explored as cathode materials, with well-documented chemistry, crystal structures,
and electrochemical properties. In contrast, PBAs with Cr or Mn as the active
site display lower redox potentials and remain significantly underexplored as
anode materials. This gap has led to fewer reported compounds and a less comprehensive
understanding of their structural and electrochemical behavior, leaving the field
relatively opaque. In this perspective, we comprehensively analyze the challenges
involved in producing and employing PBAs with low redox potentials as active battery
materials. Conversely, we propose numerous horizons and ask fundamental questions
that should pave the way for future research to advance the field.

text: 'Binding precedents (súmulas vinculantes) constitute a juridical instrument
unique to the Brazilian legal system and whose objectives include the protection
of the Federal Supreme Court against repetitive demands. Studies of the effectiveness
of these instruments in decreasing the Court’s exposure to similar cases, however,
indicate that they tend to fail in such a direction, with some of the binding
precedents seemingly creating new demands. We empirically assess the legal impact
of five binding precedents, 11, 14, 17, 26, and 37, at the highest Court level
through their effects on the legal subjects they address. This analysis is only
possible through the comparison of the Court’s ruling about the precedents’ themes
before they are created, which means that these decisions should be detected through
techniques of Similar Case Retrieval, which we tackle from the angle of Case Classification.
The contributions of this article are therefore twofold: on the mathematical side,
we compare the use of different methods of Natural Language Processing — TF-IDF,
LSTM, Longformer, and regex — for Case Classification, whereas on the legal side,
we contrast the inefficiency of these binding precedents with a set of hypotheses
that may justify their repeated usage. We observe that the TF-IDF models performed
slightly better than LSTM and Longformer when compared through common metrics;
however, the deep learning models were able to detect certain important legal
events that TF-IDF missed. On the legal side, we argue that the reasons for binding
precedents to fail in responding to repetitive demand are heterogeneous and case-dependent,
making it impossible to single out a specific cause. We identify five main hypotheses,
which are found in different combinations in each of the precedents studied.'
